Technical Field

The invention relates to a device for lens treatment, in particular for spectacle lens treatment, in particular according to the preamble of claim 1, in particular to a device for lens treatment, in particular according to the preamble of claim 19 or 20, in particular to a device for lens treatment, in particular for spectacle lens treatment, a measuring device for measuring a lens, in particular to a method for lens treatment, in particular for spectacle lens treatment, according to the preamble of claim 30 or 31.

Background

A generic device and a generic method are known from DE 4127094 a 1. This document discloses a processing station for edge processing of lenses, which processing station has a handling device in the form of a gripping arm, three edge processing means and at least two sensors for measuring and/or aligning the lens to be processed. The handling device takes the lens to be treated from the storage container and then transports it first to the device for aligning the lens and then to the edge treatment device. This process is repeated until all edge processing devices are loaded. When the edge processing is completed, the completed lens is removed from the edge processing apparatus and then placed back in the library. The disadvantage here is that the processing time of the lens is relatively long from the measurement of the lens to the completion of the edge processing.

WO 2001/070460 a1 discloses an apparatus and a method for measuring and edging lenses, wherein the lenses to be edged are distributed to two processing units, each comprising a measuring device and an edging device.

US 2007/0264915 a1 describes a device for edge processing of an ophthalmic lens, wherein a measuring device coupled with a loading table and the edge processing device for the ophthalmic lens are linked by means of a loading arm.

One workpiece spindle holds one lens during processing in the fine processing zone while the other workpiece spindle holds a second lens in the coarse processing zone. After the treatment in the finishing zone, the spindle arrangement is rotated, in particular by 180 °, so that the workpiece spindle located in the finishing zone is pivoted into the rough treatment zone and the lens located in the rough treatment zone is pivoted into the finishing zone. This is advantageous for high throughput.

Preferably, when machining the lens in the finishing zone, the lens is loaded into a workpiece spindle located in the roughing zone, unloaded from the workpiece spindle located in the roughing zone, and/or machined in the roughing zone. This is advantageous for high throughput.

It is further preferred that the transport device removes the finished machined lens from the workpiece spindle in the rough treatment zone and then transfers the lens to be machined onto the workpiece spindle, in particular during the treatment of the lens in the fine treatment zone. This is advantageous for high throughput.

Preferably, the transport device takes over the finished processed lens from the workpiece spindle by means of the second gripper or suction cup, wherein the second gripper or suction cup is then rotated away and the lens to be processed is transferred onto the workpiece spindle by means of the first gripper or suction cup, while the orientation of the lens is maintained.

The device according to the invention or the method according to the invention is particularly advantageous if lenses with a treatment time above the average level enter the apparatus according to the invention, for example because their measurement and/or their treatment are above the average level due to special circumstances such as, for example, extraordinary optical properties with respect to the measurement, for example, many and/or complicated treatment steps due to a complicated required edge shape. With the device according to the invention or the method according to the invention, such a lens can be fed into its measurement and processing, for example, at a moment in which the waiting time of the lens to be processed subsequently can be minimized.

In other words: a lens to be treated with a shorter treatment time may "overtake" another lens to be treated with a longer treatment time, in particular by means of a suitable control of at least one handling device or apparatus and/or at least one transport device. Such a lens can thus be avoided from determining the operating speed of the entire device.

Due to the decoupling of the measurements and processing, and the possibility of freely selecting the order in which the lenses are fed into their measurements and processing, time consuming measurements and/or processing of one lens can be performed without unduly delaying the measurements and/or processing of subsequent lenses.

The device according to the invention and the method according to the invention are particularly suitable for edge treatment of spectacle lenses.

In the sense of the present invention, the treatment of the edge of the lens is in particular a treatment of the edge of the lens (exclusively) to adapt the lens to the spectacle frame. In particular, the edge treatment (exclusively) changes the geometry of the edge or adapts it to the spectacle frame.

The treatment device according to the invention preferably has a rough treatment zone and a fine treatment zone. Particularly preferably, the rough treatment zone is arranged in a loading area of the treatment device. The treatment device according to the invention allows the simultaneous and/or time-overlapping edging of two lenses, i.e. the rough treatment of the first lens and the fine treatment of the second lens. This can save a lot of time in the edge processing of the lens.

Advantageous further embodiments result from the dependent claims.

Advantageously, at least two processing devices and/or at least two measuring devices are provided. The greater the number of processing devices and measuring devices selected, the greater the number of lenses that can be processed per hour. In practice, a combination of two measuring devices and two to four processing devices has proven to be particularly suitable.

It is proposed to provide the same measuring means and/or the same processing means so that each lens can be measured and/or processed using the same procedure. However, depending on the individual case, it may also be advantageous to provide measuring devices and/or processing devices of different designs to carry out different measuring or processing procedures.

The at least one measuring device can advantageously be designed for contactless measurement by means of a deflection method, transmission radiation and/or luminescence radiation. Thus, lenses with different optical properties can be measured as fast as possible. Of course, the at least one measuring device can also be equipped in a manner known per se, for example with a probe for tactile measurement.

In particular, the handling device or handling apparatus preferably has a first handling unit for transferring the lenses from the at least one transport container to the at least one measuring device and/or from the at least one transport device to the at least one transport container, and preferably a second handling unit for transferring the lenses from the at least one measuring device to the at least one transport device. In this way, in particular, a separation of the at least one measuring device from the two or more processing devices can be achieved in an at least particularly simple manner, i.e. the processing devices are freely selected after the measurement of the lens to be processed.

Advantageously, the at least one holding device forms a buffer zone for the lens to be processed and/or its transport box. This measure enables a free choice of the treatment sequence of the lenses to be treated in a particularly simple manner. In particular, the buffer device may have at least two, preferably at least three conveyor belts, which are expediently arranged parallel to one another. In the latter, the central belt is used for circulating transport boxes, each of which can be guided from the outer conveyor belt onto the central belt and then back onto the outer conveyor belt.

Advantageously, the device according to the invention has at least one measuring region for at least one measuring device and at least one processing region for at least one processing device. Thus, the measurement region(s) and the processing region(s) can be spatially separated from each other in a simple manner.

The receiving area or the receiving device can advantageously be arranged in the measuring area to ensure easy transport of the lens into at least one measuring device arranged spatially adjacent.

Advantageously, the at least one transport device extends over the at least one measurement region and the at least one treatment region to bridge a spatial separation between the at least one measurement region and the at least one treatment region.

The at least one measuring region and the at least one treatment region can also be separated from one another by a separating wall. In this case, the at least one conveying device can advantageously pass through at least one opening provided in the partition wall.

Preferably, the method according to the invention is designed such that the respective measuring device and/or the respective processing device can be selected according to the measuring and/or processing capacity of the respective lens to be processed and/or according to the available capacity on the measuring device and/or the processing device. In particular, it is possible to choose whether one or more measuring devices or one or more processing devices are selected and/or whether the same or different measuring devices or the same and/or different processing devices are used to carry out the method according to the invention. This allows for rapid and flexible measurement and handling of the lens. The dead time of the at least one measuring device or the at least one processing device may be minimized. Lenses with a higher than average measurement and/or treatment time may be selected for measurement and treatment, so that the waiting time of subsequent lenses with e.g. shorter measurement and/or treatment times may be minimized or even avoided altogether.

An advantageous further development of the method according to the invention is that at least two lenses can be measured and/or processed simultaneously. It is particularly preferred to treat at least four lenses simultaneously, since the treatment of the lenses usually takes longer than the measurement of the lenses.

The treatment device according to the invention preferably has two workpiece spindles, in particular each workpiece spindle is arranged in a spindle housing, preferably wherein the two spindle housings are designed to be pivoted relative to one another such that they can be alternately pivoted into a rough treatment zone and a fine treatment zone of the device according to the invention. The lens to be processed can thus be fed to the different processing steps in a particularly simple manner with different, freely selectable tools.

If the two spindle housings are arranged offset from one another, the "flying circle" is reduced in an advantageous manner, i.e. the radius remains free for the movement of the two housings.

Detailed Description

Fig. 1 to 5 show various embodiments of the device according to the invention, in which identical or equivalent parts are given the same reference numerals.

Fig. 1 shows an example of the basic structure of a first embodiment of an apparatus 1 for lens treatment according to the invention. In an exemplary embodiment, the apparatus 1 according to the present invention is used for measuring and chip-removing edge machining a lens to be treated, in particular in such a way that a finished edge machined lens, in particular a finished edge machined lens comprised in a spectacle frame (not shown), is obtained according to specified production data and/or frame data.

The device 1 according to the invention preferably has a housing 10 which is preferably substantially divided into a measurement region 10a and a treatment region 10 b.

The housing 10 is particularly useful for safety in operation, for example, with respect to breakage of a tool or spindle, acoustic protection and protection against debris.

It can be designed in one or several pieces, in particular divided into a housing part for the measuring region 10a and a housing part (not shown) for the processing region 10 b. Accordingly, the device 1 according to the invention can be constructed on a single base frame or on a multi-part base frame, in particular a base frame part for the measuring region 10a and a base frame part (not shown) for the processing region 10 b.

In the measuring area 10a at least one measuring device 40, 110 is provided for measuring and/or aligning the lens to be treated, while in the treatment area 10b at least one treatment device 50 is arranged for edging the lens, in particular by chip removing edging.

Preferably, the measurement area 10a and the treatment area 10b of the device 1 according to the invention are separated from each other by a separating wall 11. The partition wall 11 is intended to at least minimize contamination of the measuring area 10a with debris waste generated during the lens debris-removing machining process.

Preferably, at least one conveying device 30a, 30b passes through a respective opening 11a, 11b in the partition wall 11. The openings 11a, 11b are preferably provided with doors (not shown) which expose the openings 11a, 11b before the passage of the lenses conveyed by the conveying means 30a, 30b and close the openings 11a, 11b again after the passage.

The at least one conveying device 30a, 30b serves to convey the lenses to be treated away from the at least one measuring device 40, 110, i.e. from the measuring area 10a, to the at least one processing device 50, and to convey finished treated lenses from the at least one processing device 50 back to the measuring area 10a of the apparatus 1 according to the invention.

Preferably, an outer conveyor belt 12 is arranged adjacent to the measuring area 10a on the housing 10 for feeding the lens to be processed to the apparatus 1 according to the invention or for transporting the finished edge-processed lens away from the apparatus 1 according to the invention.

The lenses are preferably housed in a shipping container 13.

The outer conveyor belt 12 may preferably form part of a larger and/or more complex conveyor system, in particular a linear or endless conveyor system, for conveying the lens blanks and the partially and fully processed lenses to and from various processing devices (not shown). However, instead of the outer conveyor belt 12, other transport means for the lenses are also conceivable.

Further, it is preferable to arrange an operation unit 14a attached to the rotating arm 14 on the housing 10. The operating unit 14a preferably has a display device, in particular for displaying control menus and/or processing states of the lenses, and an input device, in particular preferably for centrally inputting control commands and/or display requests. By means of the operating unit 14a, the at least one conveying device 30, the at least one measuring device 40, 110 and the at least one processing device 50 can be monitored by an operator and/or controlled by means of data input. Furthermore, the treatment status of the lens can be monitored.

The swivel arm 14 is used to swivel the operating unit 14a in any direction to either side of the housing 10 of the device 1 according to the invention. Depending on the position of the operating unit 14a relative to the housing 10 or relative to the at least one measuring device 40 and/or the at least one processing device 50, the operating unit 14a can be designed to display different display and/or control menus, for example for the at least one measuring device 40 and/or the at least one processing device 50.

Of course, the operation of the device 1 according to the invention can also be realized by means of differently constructed or designed operating means, in particular by means of wireless operating means such as tablet computers, laptop computers or the like, which can also preferably display different display menus and/or control menus, for example for the at least one measuring means 40 and/or the at least one processing means 50, depending on their position relative to the housing 10 or the at least one measuring means 40 and/or the at least one processing means 50.

The switchgear cabinet 15 houses, in a manner known per se, the components necessary for the power supply, operation and control of the apparatus 1 according to the invention.

Fig. 2 shows a plan view of a second embodiment of a device 1' according to the invention. The housing 10 and the separating wall 11 between the measuring region 10a and the process region 10b are shown only for reasons of clarity.

The outer conveyor belt 12 is used to convey the transport boxes 13 of the lenses 16a, 160 to be processed for transport to the apparatus 1 'according to the invention and the transport boxes 13 with the finished processed lenses 16b for transport from the apparatus 1' according to the invention.

The transport box 13 is provided with a data carrier 13a, for example a bar code, an RFID chip or the like. The data carriers 13a may themselves contain production data and/or frame data assigned to their lenses 16a, 160 to be processed. However, the data carriers 13a may also contain only identification data, for example a serial number or the like, assigned to their mirror 16a, 160, for example. In this case, the production data and the frame data are stored, for example, in a control unit or a control center (see below) and linked to the corresponding identification data assigned to them.

The conveyor belt 12 is preferably operatively connected with two buffer zones 17a, 17b arranged in the measuring zone 10a of the apparatus according to the invention, said buffer zones forming a buffer zone 17. The buffer belts 17a, 17b may be designed as roller conveyors or conveyor belts, for example, and in an exemplary embodiment, provide space for a maximum of eight transport boxes 13.

The buffer belt 17a preferably transports the transport box 13 away from the transport belt 12 and into the measurement region 10a in the direction of the arrow E, while the buffer belt 17b transports the transport box 13 out of the measurement region 10a in the direction of the transport belt 12 in the direction of the arrow R.

The transport box 13 is pushed from the conveyor belt 12 onto a buffer belt 17a in a manner known per se, for example by means of a pusher 12 a. The transport box 13 is also advanced on the buffer strips 17a, 17b in a manner known per se, for example by means of a stop device 18 (see fig. 6a, 6 b).

The stop means 18 can also be designed, for example, as a pusher which can be moved transversely to the conveying direction of the conveying box 13 (i.e. transversely to the arrow E or R) in a manner known per se.

At the transition between the conveyor belt 12 and the buffer belt 17a, there is preferably provided a reading device 19, for example a laser scanner (see fig. 6a, 6b), which reads out production data and/or frame data stored on the data carrier 13a for the lenses 16a, 160 to be processed located therein and transmits these data to the control system of the apparatus 1' according to the invention.

It is also possible to provide pushers on the end (not shown) of the buffer belt 17a in order to push the transport boxes 13 from the buffer belt 17a onto the buffer belt 17b transversely to the transport direction of the transport boxes 13, i.e. transversely to the arrow E or R, in a manner known per se.

The buffer 17 or buffer strips 17a, 17b preferably serve as buffer storage for the transport containers 13.

This is particularly useful because the lenses 16a, 160 to be processed do not have to be fed to their measurement and processing in the same order in which they reach the buffer zone 17 a. Instead, the lenses 16a, 160 arriving later to be treated can be measured and treated first, while the lenses 16a, 160 arriving earlier to be treated are conveyed further in their transport boxes 13 along arrows E and/or R until they are selected for measurement and treatment by the control system of the apparatus 1' according to the invention. Thus, it can be said that a lens 16a, 160 arriving later can "overrun" a lens 16a, 160 already in the buffer zone 17 with respect to the order in which it is measured and processed. This has the advantage that, for example, the measurement and treatment of the lenses 16a, 160 is only performed when the lenses 16a, 160 having a measurement and/or treatment time above the average level (e.g. measuring and/or treating complex lenses) slow down the entire process of lens measurement and lens treatment in the apparatus 1' according to the invention to the minimum possible extent.

As a result, subsequent lenses 16a, 160 can be transported to the idle measuring device 40, 110 and/or the idle processing device 50, and thus be fed to their measurement and processing, after a "waiting time" which is as short as possible. At the same time, "dead time" (i.e. waiting time without lens treatment) on the at least one measuring device 40, 110 and the at least one processing device 50 is reduced as much as possible and is completely avoided in the best case.

To support the damping effect, it is also conceivable to provide a third conveyor belt (not shown) between the two damping belts 17a, 17b, which third conveyor belt is arranged running parallel to the damping belts 17a, 17b and whose principle is known, for example, from WO 2013/131656a 2. Such a third conveyor belt makes it possible to push the transport box 13, preferably from the buffer belt 17b onto the third conveyor belt, preferably by means of a pusher (not shown) known per se, if the lenses 16a, 160 accommodated in the transport box 13 are not yet intended for measurement or processing. In this case, a third conveyor belt (e.g., buffer belt 17a) will transport the transport box 13 in the direction of arrow E. As a result, the transport box 13 will then circulate on the third conveyor belt and the buffer belt 17 b. Of course, such circulation of the transport box 13 on the third transport belt and the buffer belt 17a is conceivable. In this case, the third transport belt will transport the transport box 13 in the direction of arrow R.

In the measuring region 10a, two measuring devices 40, 110 are provided in the exemplary embodiment, which are preferably identical in construction. Each of the measuring devices 40, 110 can measure the lens 16a, 160 to be processed, in particular so that the measured lens 16a to be processed can be transferred in a manner known per se onto the at least one processing device 50 in the correct spatial orientation, thereby obtaining finished edge-processed lenses 16b corresponding to their respective production data and/or frame data.

In the exemplary embodiment, two measuring devices 40, 110 are connected to two conveying devices 30a, 30 b. The transfer of the lenses 16a, 160 to be treated from their transport boxes 13 to the freely selectable measuring device 40, 110, from the measuring device 40 to the freely selectable transport device 30a, 30b and the transfer of the finished edge-treated lenses 16b from the transport device 30a, 30b back to their transport boxes 13 is carried out via a handling device or apparatus 20, as shown in fig. 6a, 6b and 12 (see below).

The transport means 30a, 30b preferably transport the measured and aligned lens 16a to be processed from the measurement area 10a to the processing area 10b of the apparatus 1' according to the invention while maintaining its spatial orientation.

As can also be seen from the exemplary embodiment according to fig. 1, the conveying means 30a, 30b preferably pass through openings 11a, 11b in the separating wall 11 between the measurement region 10a and the treatment region 10 b. The separating wall 11 is intended to at least minimize contamination of the measuring area 10a by chip debris generated during machining of the chip removing edge of the lens 16 a. For this purpose, the openings 11a, 11b through which the transport devices 30a, 30b pass are preferably provided with doors (not shown) which expose the openings 11a, 11b before the lenses 16a, 16b conveyed by the transport devices 30a, 30b pass and close them again after passing.

In the exemplary embodiment, two preferably identically constructed processing devices 50 are arranged in the processing region 10b, which processing devices 50 are connected to the conveying devices 30a, 30 b.

In the exemplary embodiment, they are edge processing devices 50 that are divided into a rough processing region 51 and a fine processing region 52, respectively.

First, an initial chip removing edge machining operation is performed on the lens 16a to be processed in a rough treatment zone 51 in which the desired contour of the lens 16a is approximately produced.

The lens 16a pre-machined in this manner is then preferably transferred to a finishing zone 52 where the desired contour is completed. The now finished edge-machined lens 16b is then preferably transferred again to the transport means 30a, 30b, transported back to the measuring area 10a of the apparatus 1' according to the invention and placed again in the associated transport box 13.

In order to remove the debris waste generated during the machining of the edge of the lens 16a, a suction opening 69 can be provided in the bottom of the treatment zone 10b, for example, in a manner known per se connected to a suction system having a duct for conveying the debris waste.

Advantageously, the conveying means 30a, 30b and the treatment means 50 are attached to a supporting frame that spans the treatment area 10b (not shown), in order to reduce as much as possible their pollution and to make it possible to suck up the scrap waste without difficulty. The bottom of the treatment zone 10b can then also be designed, for example, in the form of a trough 68, in particular in order to simplify the collection of debris waste in the region of the suction opening 69. If necessary, such a suction process can then also be designed to take place discontinuously and thus in an energy-saving manner and with less noise interference.

Preferably, two lenses 16a can be processed simultaneously in each processing device 50, wherein each lens 16a is located in the rough processing zone 51 in each case and each lens 16a is located in the fine processing zone 52 in each case. Preferably, therefore, in this exemplary embodiment of the device 1' according to the invention, two lenses 16a can be measured and four lenses 16a can be edged simultaneously and/or in a time-overlapping manner.

Preferably, the housing 10 encloses the measuring device 40, 110, the conveying device 30a, 30b, the processing device 20, the processing device 50 and/or the buffer zone 17, in particular laterally and/or completely.

Fig. 3 shows a plan view of a third embodiment of the device 1 "according to the invention. The device 1 "substantially corresponds to the device 1' according to fig. 2 and has substantially the same components. Therefore, the same reference numerals have been used in this respect, and reference is made in this respect to the description above with respect to fig. 2.

The essential difference between the device 1' according to the invention as shown in fig. 2 and the device 1 ″ according to the invention as shown in fig. 3 is that the measuring means 40, 110 are not arranged next to one another but are arranged staggered with respect to one another. The conveying devices 30a, 30b are therefore arranged parallel to one another and each connect a measuring device 40, 110 to a processing device 50.

The transfer of the lenses 16a, 160 to be treated from their transport boxes 13 to the freely selectable measuring device 40, 110, from the measuring device 40, 110 to the freely selectable transport device 30a, 30b and the transfer of the finished treated lenses 16b from the respective transport device 30a, 30b back to their transport boxes 13 takes place via a handling device or handling apparatus 20, as shown in fig. 6a, 6b and 11 (see below).

Fig. 4 shows a top view of a fourth embodiment of a device 1 "' according to the invention.

The device 1 "'substantially corresponds to the device 1' according to fig. 2 and has substantially identical components. Therefore, the same reference numerals have been used in this respect, and reference is made in this respect to the description above with respect to fig. 2.

The essential difference between the apparatus 1 'according to the invention as shown in fig. 2 and the apparatus 1 "' according to the invention as shown in fig. 4 is that several measuring devices 40, 110, in the exemplary embodiment two measuring devices, are provided, to which a measuring station 42 is assigned for receiving the lens 16a, 160 to be processed. The transport devices 30a, 30b are arranged parallel to one another and connect the measuring table 42 to a processing device 50 in each case. The lens 16a, 160 to be processed is removed from its transport box 13, placed on the measuring table 42 for measurement and fed to the respective measuring device 40, 110 by means of the rotation of the measuring table 42. After the measurement, the measured lens 16a still to be processed is transferred to the transport device 30a, 30b while maintaining its orientation; instead, the finished processed lenses 16b are transported back to the measuring area 10a by the transport devices 30a, 30b and transferred to the transport boxes 13 assigned to them.

The transfer of the lenses 16a to be processed from their transport boxes 13 to the measuring station 42, from the measuring station 42 to the freely selectable transport devices 30a, 30b and the transfer of the finished processed lenses 16b from the respective transport devices 30a, 30b back to their transport boxes 13 is carried out by means of a handling device or handling apparatus 20, as exemplarily shown in fig. 6a, 6b and 11 (see below).

Fig. 5 shows a top view of a fifth embodiment of a device 1 "" according to the invention. The device 1 "" is substantially identical to the device 1' shown in fig. 2 and has substantially identical components. Therefore, the same reference numerals are used in this respect, and reference is made in this respect to the above description of fig. 2.

The essential difference between the device 1' according to the invention as shown in fig. 2 and the device 1 "" according to the invention as shown in fig. 5 is that the measuring means 40, 110 and the processing means 50 are arranged by turning 90 °. This allows the housing 10 "" to have a shortened design, as shown by means of dashed lines.

The transfer of the lenses 16a, 160 to be treated from their transport boxes 13 to the freely selectable measuring devices 40, 110, from the measuring devices 40, 110 to the freely selectable transport devices 30a, 30b and the transfer of the finished treated lenses 16b from the respective transport devices 30a, 30b back to their transport boxes 13 is carried out via a handling device or handling apparatus 20, as is exemplarily shown in fig. 6a, 6b and 11 (see below).

Fig. 2 to 5 thus show, by way of example, the construction principle by which the device 1, 1', 1 "', 1" ", according to the invention, is characterized. The construction principle includes the arrangement of at least one measuring device 40, 110 with at least one processing device 50 and their connection by means of at least one conveying device 30a, 30 b.

As a result, in an exemplary embodiment, the lens to be processed 16a, 160 is measured and edged according to defined production data and/or frame data to obtain a finished processed lens 16b, which can then be inserted into the spectacle frame.

The number of measuring devices 40, 110 and processing devices 50 to be combined may be selected as desired, for example, based on the selection of the design and/or operating mode of the respective measuring device 40, 110 and processing device 50, the measurement or processing speed of each lens 16a, 160, and the like.

The measuring means 40, 110 and the processing means 50 may be arranged or oriented in any way with respect to each other with respect to the device 1, 1', 1 "', 1" ", for example depending on their size and/or structure.

The design and number of the conveying devices 30a, 30b can then be selected as a function of the number and, if necessary, also of the arrangement of the measuring devices 40, 110 and the processing device 50 in the respective apparatus 1, 1', 1 "', 1" ".

In the exemplary embodiment according to fig. 2 to 5, two measuring devices 40, 110 and two processing devices 50 with a rough processing zone 51 and a fine processing zone 52, respectively, are selected. However, this choice may be changed, altered and/or expanded as desired.

Furthermore, the camera 122 or the camera objective 123 preferably has a filter device (not shown) for absorbing and/or deflecting excitation radiation emitted by the laser diode 141 (see below).

The opening 124 in the holder 121 and the recess 114 in the holding table provide a free measuring path for the camera objective 123 in the vertical direction, defining a vertically extending measuring axis M'.

The gripping device 134 is used to grip and center the lens 160. By means of a rack-and-pinion transmission, the holding plate 131 and thus the clamping device 134 can be moved vertically along the guide rail 133b in the direction of the z' -axis.

In an exemplary embodiment, the gripping element 135 may be pneumatically moved. Thus, in this exemplary embodiment, a pneumatic cylinder drive 136 for moving the clamping element 135 is provided below the holding plate 131.

The storage station 137 is preferably arranged below the clamping device 134.

Preferably, the first radiation source 140 is further arranged on the top side 113 of the holding plate 111. In the exemplary embodiment, the first radiation source 140 includes two groups 140a, 140b of four laser diodes 141. In the exemplary embodiment, the laser diodes 141 of each group 140a, 140b are arranged parallel to each other, with two rows of laser diodes of each group, and at an angle of 15 ° with respect to the z 'axis or with respect to the measurement axis M'.

Computer Generated Holograms (CGH) may also be used. In an exemplary embodiment, the laser diodes 141 are further arranged offset from each other. As a result, the linear rays emitted by the laser diodes 141 are also offset or spaced from each other perpendicular to their direction of propagation.

In an exemplary embodiment, the distance between the linear rays is about 10 mm.

The laser diodes 141a of the two groups 140a, 140b are again arranged at right angles to each other. The laser diodes 141 are connected by a line 142 to a power supply device (not shown) so that they can be switched independently of each other and in any combination.

Preferably, a receiving plate 151 for receiving the second radiation source 150 is arranged below the driving unit 116 for the rack and pinion gear. In an exemplary embodiment, a TFT-based liquid crystal flat panel display is provided as the second radiation source 150. The second radiation source 150 is preferably arranged above the clamping device 134 and in a plane oriented perpendicular to the z '-axis or the measuring axis M'.

As described above, the measurement device 110 may also be comprised of two parts, each part having the camera 122, the first radiation source 140, and the second radiation source 150. Then, as exemplarily shown in fig. 10, a clamping and centering arrangement 144 may be provided.

The arrangement 144 has a total of two pairs 145, in each case two clamping devices 134 as described above with clamping elements 135. In each case, the clamping device 134 of each pair 145 is assigned to a part of the measuring device 110 with the camera 122, the first radiation source 140 and/or the second radiation source 150.

The clamping devices 134 of the pair 145 and/or of the pair 145 are preferably arranged in a common, in particular horizontal, plane. It is also evident from fig. 12, where four clamping devices 134 are shown on the right side of the figure.

The gripping devices 134 of each pair 145 are preferably mounted on a turning device 146 so as to be turned 180 deg. in the direction of arrow D.

In other words, each of the pairs 145 of clamping devices 134 is rotatable about a preferably vertical axis, in particular by 180 °, particularly preferably such that the pairs 134 exchange their positions during the rotation by 180 °. Preferably, the rotating means 146 form an axis of rotation of the pair 145. The turning device 146 is preferably arranged below the clamping device 134 and/or between both clamping devices 134 of the pair 145.

As mentioned above, the gripping devices 134 of each pair 145 are also preferably associated with a respective storage station 137. Preferably, each storage station 137 is designed to be height-adjustable and/or arranged or arrangeable by means of an adjusting device 147 such that it is in a loading position according to fig. 8 (right half of fig. 10) relative to its assigned clamping device 134 or in a measuring position according to fig. 9 (left half of fig. 10) relative to its assigned clamping device 134.

The second clamping devices 134, which are arranged in the image background in fig. 10, are preferably positioned relative to their assigned elements, i.e. the camera 122, the first radiation source 140 and/or the second radiation source 150, in such a way that measurements (described in more detail below) can be made.

In the position according to the right half of fig. 10, the lens 160 to be measured can be loaded or unloaded on the front gripping device 134, while the lens (not shown) is held and measured in the rear gripping device 134, as described below.

In the position according to the left half of fig. 10, the lens 160 to be measured can be held in the front clamping device 134, while the finished measured lens 160 can be held in the rear clamping device 134 (not shown), so that the pair 145 can be turned 180 °. Then, the lens 160 to be measured may be measured as described below, and the completed measured lens 160 may be unloaded as described below.

In the following, an example of a measurement method is described (see fig. 8, 9 and 11):

at the beginning of the process, the clamping device 134 of the device 110 according to the invention is preferably in its loading position (see fig. 8, fig. 10, right). In this loading position, the storage table 137 is preferably arranged directly below the clamping device 134.

First, in a method step 201, the device 110 is loaded (see WO 2016/095939a1) with the optically active element to be measured, in an exemplary embodiment a lens 160, possibly provided with a coating 160', for example for an eyeglass lens, in a manner known per se by placing the optically active element to be measured on a storage table 137. Here, the mirror 160 is preferably oriented in such a way that its bottom side 162, which in the exemplary embodiment is concave, is oriented towards the camera objective 123, and its top side 161, which in the exemplary embodiment is convex, is oriented towards the second radiation source 150.

Furthermore, in method step 202, the clamping element 135 is first actuated, so that the lens 160 is centered along its circumference with respect to the clamping element 135 within the clamping device 134.

Subsequently, in a method step 202, the gripping element 135 of the gripping device 134 is actuated such that the lens 160 is gripped by means of the gripping element 135 while substantially maintaining the centering of the lens 160.

In method step 203, the clamping device 134 is first moved in the z '-axial direction to such an extent that the storage table 137 can be rotated out of the measuring region of the camera objective 123 of the camera 122 so as not to interfere with the measuring axis M' of the camera objective 123.

Finally, in method step 203, the clamping device 134 together with the lens 160 clamped therein is moved further upward along the z' -axis towards the second radiation source 150 by means of a rack-and-pinion transmission.

The clamping device 134 of the device 110 according to the invention is now in a defined measuring position (see fig. 9, fig. 10 left). The measuring position can be kept constant irrespective of the nature of the optically active element to be measured, thereby contributing to standardizing the method according to the invention.

The three measurement methods can be performed sequentially or simultaneously (see fig. 10):

determining the spatial position of the bottom side 162 of the lens 160

i. In a method step 204, each laser diode of the two groups 140a, 140b of laser diodes 141 emits a line-shaped radiation, in the exemplary embodiment the excitation radiation has a wavelength of 405nm or 450 nm. These defined wavelengths can be filtered out of the radiation emitted by the laser diode 141, for example by means of a filter, not shown.

Since the laser diodes 141 are arranged perpendicularly with respect to the propagation direction of each other, the line-shaped rays emitted by the laser diodes 141 have an interval of about 10 mm. As a result, in the exemplary embodiment, the line-shaped rays emitted by all eight laser diodes are incident on the material of the mirror 160 and/or its coating 160' in the form of two sets of four lines arranged at right angles to each other. The fluorescent radiation of the lens 160 and/or the material of its coating 160' of wavelengths greater than 405nm or 450nm excited by the linear rays arranged in this way is emitted in two groups, each group having four lines arranged at right angles to each other and spaced apart from each other (i.e. in the form of a grid or lattice pattern).

in the exemplary embodiment, two sets of four line rays arranged at right angles to each other are incident on the bottom side 162 of the lens 160, the bottom side 162 of the lens 160 being concave in the exemplary embodiment. Thus, the fluorescent radiation emitted by the lens 160 and/or the material of its coating 160' forms a grid or grid pattern of two by four fluorescent lines, the wavelength of which in exemplary embodiments is greater than 405nm or 450 nm. In an exemplary embodiment, this fluorescent radiation is captured by the camera objective 123 in method step 205 and detected by the CCD sensor of the camera 122. The fluorescence radiation can be detected particularly reliably and with low interference if the camera 122 or the camera objective 123 has a filter for absorbing or deflecting the excitation radiation emitted by the laser diode 141. The resulting measurement data is fed to the evaluation unit 170.

The measurement data are evaluated by means of triangulation (fringe projection as 3D measurement method) which is known per se. In this way, the spatial position of the bottom side 162 of the lens 160, which in the exemplary embodiment is concave, is determined in a manner known per se. For asymmetric lenses (e.g., free form lenses), the measurements are unambiguous. For a symmetric lens (e.g. a spherical lens), data on its edge profile (see below) is still needed to determine its position in space.

v. by performing the above method using a flat glass as the measurement object, the device 110 according to the invention can be calibrated.

Determining parameters of a lens 160

i. In a method step 206, a second radiation source 150 (in the exemplary embodiment a TFT-based LCD screen) emits radiation in a defined pattern (e.g., a stripe pattern) in the direction of a top side 161 of the mirror plate 160, which top side 161 of the mirror plate 160 is convex in the exemplary embodiment. The radiation passes through the lens 160, wherein the defined pattern is modified according to the parameters of the lens 160, in particular its profile, its edge profile, any markings (e.g. laser engraving) and/or any multifocal zone (e.g. bifocal or trifocal zone) of the lens 160. In a method step 207, the generated transmitted radiation is captured by the camera objective 123 of the camera 122 and, in an exemplary embodiment, detected in the form of a measurement signal by means of a CCD sensor of the camera 122. The measurement data resulting from the transmission measurement is fed to an evaluation unit 170 and evaluated.

The device 110 according to the invention can be calibrated by performing the above method using a flat glass as the object of measurement.

Determining the refractive power of the lens 160

i. In a method step 208, the second radiation source 150 (in the exemplary embodiment a TFT-based LCD screen) emits radiation in the form of defined pixels in the direction of a top side 161 of the mirror plate 160, which top side 161 of the mirror plate 160 is convex in the exemplary embodiment. The radiation passes through the optic 160 where it is deflected according to the optical characteristics of the optic 160. In an exemplary embodiment, in method step 209, the generated transmitted radiation is captured by the camera objective 123 of the camera 122 and detected in the form of a measurement point by means of the CCD sensor of the camera 122.

For evaluating the measurement points, a ray tracing method known per se (i.e. a ray-emission based algorithm for tracing the determined measurement points back to their source, i.e. the defined pixels) is used in the exemplary embodiment. By means of a ray tracing method, the resulting measurement points detected by the CCD sensor of the camera 122 are associated with pixels arranged on the second radiation source 150 (i.e. the source points of the rays detected in the form of measurement points). In order to assign the measurement points captured by the CCD sensor to the pixels defined in the second radiation source 150, the second radiation source 150 is correspondingly coded in a manner known per se. The measurement data resulting from the transmission measurement and the ray tracing method are fed to an evaluation unit 170. In this measuring method, it is advantageous if the defined pattern of rays emitted by the second radiation source 150 is selected in such a way that: so that a sufficient signal separation, i.e. a sufficient resolution of the measurement signals, can be achieved on the CCD sensor, so that in the best case each measurement signal can then be evaluated.

Evaluation of the measurement data gives the refractive power of the lens 160.

The device 110 according to the invention can be calibrated by performing the above-described procedure using a flat glass as the object of measurement.

The linking of these measurement data allows a two-dimensional assessment (so-called "diopter map") of the refractive power of the lens 160 to be determined in method step 210. This allows, among other things, the prisms incorporated into the lens 160 to be distinguished by order and prism imperfections. This applies both to prism errors that occur during the shaping process of the bottom side 162 of the lens 160 and to prism errors that are detected due to incorrect positioning of the lens 160 in the device 110.

The above described methods for determining the spatial position of the lens 160 (item 1) and for determining its parameters (item 2) can also be performed in a deflection method. For this purpose, radiation emitted by a radiation source, the lens 160 of which is opaque, is used. The radiation source is positioned such that the mirror 160 reflects radiation emitted by the radiation source in the direction of the measurement axis M', i.e. in the direction of the camera objective 123, so that the resulting reflected radiation can be captured by the camera objective 123 and detected by the CCD sensor of the camera 122. The resulting measurement data are then evaluated in a manner known per se.

Fig. 12 and 13 show in plan view exemplary embodiments of a conveying device 30a, 30b, which preferably cooperates with a control device or control device 20 in the measurement region 10a and/or with two processing devices 50 in the processing region 10b of the device 1, 1', 1 "', 1" ".

In the exemplary embodiment, the conveying means 30a, 30b are designed as linear conveyors 31a, 31b and are preferably attached to a not shown support frame of the device 1, 1', 1 "', 1" ", according to the invention.

In the exemplary embodiment, each linear conveyor 31a, 31b has, in a manner known per se, a guide rail 32a, 32b for guiding a carriage 33. In the exemplary embodiment, the carriage 33 is arranged on pneumatically driven rails 32a, 32b so as to be movable in the direction of arrow S (conveyor 30a) or in the direction of arrow T (conveyor 30 b). However, the carriage 33 may also be electrically driven.

The rigid holder 34 with the first gripper or suction cup 34a and/or the holder 35 with the second gripper or suction cup 35a can be pivoted about a pivot axis D, preferably arranged on the carriage 33.

A first gripper or suction cup 34a is preferably used to receive the lens 16a that has been measured and aligned for edging, while a second gripper or suction cup 35a is preferably used to receive the finished edged lens 16 b.

The first gripper or suction cup 34a is therefore preferably designed in a manner known per se such that it can receive a lens 16a, which lens 16a has already been measured and aligned in its respective alignment for edge processing and which alignment is maintained during transport of the lens 16a to the processing device 50.

Instead, the second gripper or suction cup 35a can have a simple design so that it can receive the finished edged lens 16b in any orientation.

In this exemplary embodiment, the axes x, y and z mentioned below are oriented orthogonally to each other, preferably the x and y axes are horizontal and the z axis is vertical (see also fig. 6a, 6 b).

Fig. 13 to 14b show an exemplary embodiment of a processing device 50 according to the present invention, which is preferably suitable for a device 1, 1', 1 "', 1" ", and/or for carrying out a method according to the present invention. In the exemplary embodiment, two processing devices 50 according to the present invention having the same structure are provided.

In the exemplary embodiment, the two processing devices 50 are attached to a support frame (not shown), in particular at a distance from the trough 68 or the suction opening 69, in order to ensure an undisturbed discharge of the debris waste.

Each processing device 50 preferably has a rough processing area 51 and a fine processing area 52 so that both lenses 16a can be edged simultaneously and/or overlapping in time.

Preferably, the treatment device 50 is designed for simultaneously treating the lenses in a rough treatment zone 51 and a fine treatment zone 52.

In this exemplary embodiment, the rough treatment zone 51 also serves as a loading area for the lens 16a to be treated or as an unloading area for the finished edge-treated lens 16 b.

Preferably, two workpiece spindles or integral spindle housings 53 are provided in each processing device 50.

In this exemplary embodiment, the two workpiece spindles or the one-piece spindle housing 53 are arranged such that they can be rotated by 180 ° about the rotation axis Tr in this exemplary embodiment.

Preferably, the workpiece spindle 53 or the one-piece spindle housing 53 is arranged on the rotating device 54, in particular offset from one another.

Thus, each workpiece spindle or integral spindle housing 53 is arranged to be transferable from the rough treatment zone 51 to the fine treatment zone 52 and back.

The preferred offset arrangement of the two workpiece spindles or the integrated spindle housing 53 has the effect of minimizing the radius defined by the 180 ° rotation ("flight circle").

In other words, the processing device 50 has a spindle device with two workpiece spindles 53, which are formed in particular by an integrated spindle housing 53. The workpiece spindle or integral spindle housing 53, respectively, is preferably configured to hold the lens during processing operations. The spindle arrangement preferably rotates together with the workpiece spindle 53, so that the workpiece spindle 53 can be moved from the rough treatment zone 51 to the fine treatment zone 52 and from there to the rough treatment zone.

Preferably, the workpiece spindles or integral spindle housings 53 are arranged at a fixed distance from each other.

In order to exchange the workpiece spindle 53 between the rough treatment zone 51 and the fine treatment zone 52, the spindle arrangement with the workpiece spindle or the integrated spindle housing 53 can preferably be rotated about an in particular vertical axis of rotation and/or by means of a rotation device 54, in particular by 180 °.

Each workpiece spindle or one-piece spindle housing 53 preferably has the form of a workpiece spindle, in particular two semi-spindles, namely an upper semi-spindle 55 and a lower semi-spindle 56. In the exemplary embodiment, the two semi-spindles 55, 56 are designed to be drivable in the same direction of rotation by means of an electric motor via a synchronous shaft having two belts (not shown) operatively connected to the synchronous shaft in a manner known per se. However, the two semi-spindles 55, 56 can also be driven in the same rotational direction, for example by means of associated electric motors (not shown), respectively.

This defines a vertical axis of rotation C. Preferably, the lower semi-spindle 56 is designed to be vertically movable in the direction of the axis z, in contrast to the upper semi-spindle 55, so that the lens 16a to be treated can be held in a clamped manner on both of its surfaces (not shown) between the upper semi-spindle 55 and the lower semi-spindle 56. In this case, the adhesive force transmitted by the upper semi-spindle 55 and the lower semi-spindle 56 acts on both surfaces of the lens 16a to be machined in each case.

In this embodiment, each semi-spindle 55, 56 further comprises adhesive elements (not shown) such that the surface of the lens 16a to be treated is clamped between the adhesive elements.

The adhesive element is preferably made of a resilient plastic material that is adapted to the respective surface contour of the lens 16 a. In this case, the semi-spindles 55, 56 as provided in the exemplary embodiment are advantageously designed to be rotatable in the same direction about the axis of rotation C and to be drivable individually. In this way, the torque transmitted by the motor is increased, so that a particularly safe entrainment of the lens 16a to be processed is achieved during the edging process.

In the exemplary embodiment, the rough-treatment zone 51 also preferably has only one tool spindle or tool spindle device 57 for accommodating only one tool 58, respectively, which tool 58 is used for chip-removing edge machining of the lens 16a to be treated, in particular of the lens 16a to be treated held by the associated semi-spindles 55, 56, respectively.

In the exemplary embodiment, tool spindle device 57 is held on x-bracket 59a and/or z-bracket 59b in such a way that it can be moved along the vertical z-axis and/or the horizontal x-axis. This allows the tool 58 to be advanced in the x-direction and/or z-direction towards the lens 16a to be treated.

Thus, in this exemplary embodiment, the tool spindle arrangement 57 preferably has no axis of rotation. Of course, additional axes of movement, including axes of rotation, may be provided to feed the tool 58.

In an exemplary embodiment, the tool 58 may be designed with a relatively small length dimension to minimize handling errors and risk of damage to the tool 58, for example, due to natural vibration or bending of the tool 58.

A measuring device 60 with a measuring probe 61 known per se is preferably also arranged in the rough treatment zone 51. The measuring device 60 is preferably held together with the tool spindle device 57 on the x-carrier 59a and/or on the z-carrier 59b so that it can also be moved in the x-direction and/or z-direction as described above for the tool spindle device, so that the feed of the measuring probe 61 to the lens 16a can thus take place.

The measurement device 60 is used to measure the near-edge machined lens 16a prior to transfer to the finishing area 52 of the processing device 50.

Specifically, the spatial positions of the upper and lower surfaces of the edge area of the lens 16a subjected to the approximate edge processing remaining after the rough processing are determined.

Here, the probe 61 is moved over the surface between the obtained contour of the approximated-edge processed lens 16a and the calculated contour of the desired finished processed lens 16 b. On this basis, specific production data for the finishing of the near-edge machined lens 16a can be determined.

Subsequently, they are transferred to the finishing zone 52 and the final finishing is transferred to the finished treated lens 16 b. In this manner, the most accurate finishing can be performed on the finished treated lens 16 b.

The finishing zone 52 preferably has several (in the exemplary embodiment, five) different tools 62 for chip removing machining of the lens 16a to be treated.

Each tool 62 is fixedly mounted on a tool spindle 63 and is preferably provided for a single defined processing task. However, a cluster tool may also exist, which may be provided for two or more processing tasks.

The tool 62 is preferably selected in such a way that all lens edge types can be manufactured (in particular for glasses with full-rim, half-rim and/or rimless glasses). In particular, different tools 62 are provided for different processing tasks.

The tool spindle 63 is accommodated in the holding device 64 in any order. Preferably, the tool spindles 63 are received in such a way that they can be easily replaced and/or received, so that their order can be changed.

The holding device 64 is preferably accommodated in the x-bracket 65a so as to be pivotable about a horizontally extending axis, thereby defining a pivot axis B. The x-carriage 65a is in turn designed to be movable along the x-axis. Preferably, the x-carriage 65a is in turn held on a y-carriage 65b, which y-carriage 65b is designed to be movable along a y-axis extending at right angles to the x-axis.

Finally, the y-bracket 65b is preferably held on a z-bracket 66, which z-bracket 66 is designed to be movable along a z-axis perpendicular to the plane formed by the x-axis and the y-axis.

As a result, the tool spindle 63 and its tool 62 are preferably movable in all three spatial directions x, y, z and additionally about the pivot axis B and are therefore designed to be feedable onto the respective lens 16a to be processed held by the associated semi-spindles 55, 56.

The tools 62 can be selected independently of one another for the finishing of the lens 16a to be processed and fed by means of a linear movement in the y direction respectively to the lens 16a held in the associated one-piece spindle housing 53 which has been roughly machined and then brought into engagement with the lens 16a by means of a pivoting movement about the pivot axis B. This enables full edging of the lens 16a to be processed, producing a finished edged lens 16b of full size and/or having a variety of edge shapes.

This construction according to the invention allows the edge treatment of the lens 16a with different tools 62, wherein according to the invention preferably no time-consuming tool exchange takes place, but the tools 62 required in each case are fed to the lens 16a to be treated by means of a linear displacement and a subsequent pivoting movement of the holding device 64.

Since the tool spindles 63 and thus the tools 62 are advantageously arranged in as large a spatial proximity as possible to each other (i.e. without interfering with each other when the tools 62 are fed to the lenses 16a to be processed, respectively), the feed path of the tools 62 is short, so that the feed movement itself can also be performed very quickly.

In order to save more time, the tool 62 may be activated, i.e. the tool 62 is set in a rotational movement, before the previous edge processing step has been completed, i.e. before the tool 62 is advanced to the lens 16a to be processed.

In this exemplary embodiment, the device 1, 1', 1 "', 1" ", according to the invention, has an integrated control system, in particular for all controllable components of the device 1, 1', 1"', 1 "", according to the invention, in particular for the buffer system 17, the handling device or the handling device 20, the at least one conveying device 30, the at least one measuring device 40 and/or the at least one processing device 50.

Exemplary embodiments of the method according to the present invention can be implemented with the exemplary device according to the present invention just described and preferably with the following method steps.

Preferably, the transport box 13 is transported by means of the conveyor belt 12 into the region of the device 1, 1', 1 "', 1" ", according to the invention.

Each transport box 13 contains at least one, preferably two, to-be-processed lenses 16a, 16b assigned thereto, wherein each transport box is preferably provided, for example, with identification data or production data and/or frame data 13a of the to-be-processed lens assigned thereto.

In principle, however, the lenses 16a, 16b and/or the transport boxes 13 can also be transported in other ways to the apparatus 1, 1', 1 "', 1" ", and away from the apparatus 1, 1', 1"', 1 "".

In the region of the buffer strip 17a, the transport boxes 13 are preferably pushed one by one from the conveyor belt onto the buffer strip 17a by means of the pusher 12 a.

Subsequently, each transport box 13 preferably first passes through a reading device 19, which reading device 19 reads out the identification data or production data and/or frame data 19 and passes them to the control system of the apparatus 1, 1', 1 "', 1" ".

Each transport bin 13 on the buffer belt 17a is further transported into the measuring area 10a of the apparatus 1, 1', 1 "', 1" ", according to the invention, preferably controlled by a stopping device 18, which stopping device 18 in a manner known per se allows each transport bin 13 to be further transported segment by segment according to the control of the apparatus 1, 1', 1"', 1 "".

When the transport bin 13 reaches the end of the buffer strip 17a, it can be pushed, for example, in a manner known per se by means of a pusher onto a buffer strip 17b extending parallel to the buffer strip 17 a.

Each transport bin 13 on the buffer belt 17b is preferably further transported out of the measuring area 10a of the device 1, 1', 1 "', 1" ", according to the invention, controlled by a stopping device 18, which is provided with a locking device in a manner known per se and which allows each transport bin 13 to be further transported section by section according to the control of the device 1, 1', 1"', 1 "".

During such section-by-section transport of the transport box 13, the lenses 16a to be treated assigned to them are removed from the transport box 13, in particular by means of a handling device or handling apparatus 20, and are fed to further treatment in the apparatus 1, 1', 1 "', 1" ", according to the invention.

The finished edge-treated lenses 16b are returned to the transport boxes 13 assigned to them and placed therein, in particular by means of a handling device or handling apparatus 20.

At the latest when the transport bin 13 reaches the end of the buffer belt 17b in the area of the conveyor belt 12, the finished edged lenses 16b assigned to it are loaded into the transport bin 13 and pushed back onto the conveyor belt 12 and/or, according to the invention, transported out of the area of the apparatus 1, 1', 1 "', 1" ", by means of the underlying transport bin 13.

Here, it is preferably not necessary to remove the lenses 16a to be processed in the order in which the transport boxes 13 arrive on the buffer zone 17 a.

The control system of the apparatus 1, 1', 1 "', 1" ", according to the invention preferably calculates the sequence in which the lenses 16a to be processed are to be removed from their transport boxes 13, so that the lenses 16a to be processed are removed from their respective transport boxes 13 depending on the use of the at least one measuring device 40 and/or the at least one processing device 50. This means that the measurement or alignment and edge processing of the lens 16a to be processed can be carried out at an optimum speed, in particular without waiting times, for example caused by preceding lenses 16a having long measurement and/or processing times.

Therefore, preferably, both the lens 16a to be processed and the finished edge-treated lens 16b can be removed from or placed in their transport boxes 13, irrespective of the position of the transport box 13 assigned to them on the buffer belts 17a, 17 b. At the latest when the transport box 13 reaches the end of the buffer belt 17b in the region of the conveyor belt 12, the finished edge-treated lens 16b assigned to it must be loaded into it again.

As mentioned above, by means of a third conveyor belt (not shown) the transport box can be additionally circulated to optimize the buffering effect of the buffer belts 17a, 17 b.

After the lens 16a to be processed has been removed from its transport box 13, it is transported by the handling unit 20a to the then available measuring system 40 or the respective measuring device 40. The lens 16a is placed with its convex surface facing upwards on a storage table assigned to the respective lens holder 41, so that the lens 16a can be fixed and transferred to the measuring device 40 by means of the clamping means of the lens holder 41 in a manner known per se, as described for example in WO 2016/095939a 1.

The lens 16a to be machined is measured in a manner known per se.

Subsequently, the measured lens 16a is picked up on the convex surface of the measured lens 16a, preferably at the calculated shading point, by the handling unit 20b and released from the clamping device of the lens holder 41.

The lens 16a to be treated is then aligned in a manner known per se, for example as described in WO 2016/095939a 1.

Now, the control system preferably determines to which of the transport devices 30a, 30b the lens 16a being measured and preferably aligned is transferred, in particular while maintaining its alignment. This preferably depends on which processing device 50 assigned to the respective conveying device 30a, 30b can be reloaded at this time.

Thus, the aligned lens 16a is transferred from the handling unit 20b to the suction cup/gripper 34a of the selected transport device while maintaining its orientation, which suction cup/gripper 34a now preferably grips the lens 16a at the concave surface of the lens 16 a.

Preferably, but not necessarily simultaneously, the handling unit 20a picks up the finished processed lens 16b, held by the suction cups/grippers 35a on its concave surface, from the suction cups/grippers 35a of the selected conveyor 30a, 30b, removes the lens 16b from the suction cups/grippers 35a, and places it in the delivery box 13 assigned to it.

The carriage 33 of the selected transport device 30a, 30b now moves out of the measuring region 10a of the apparatus 1, 1', 1 "', 1" ", according to the invention, along the guide 32a, 32b into its processing region 10b, preferably through the opening 11a, 11b through the partition wall 11. In the process, the doors associated with the respective openings 11a, 11b are preferably opened so that the brackets 33 can pass through the openings 11a, 11 b.

The openings 11a, 11b are then closed again, preferably by means of the door assigned to it.

When the carriage 33 is at the height of the processing device 50 in the rough treatment zone 51, the processed lens 16b is preferably transferred from the workpiece spindle or integral spindle housing 53 to the transport device 30a, 30 b.

In particular, for this purpose, the suction cup/gripper 35a moves under the upper semi-spindle 55 of the workpiece spindle or one-piece spindle housing 53 and takes over the processed finished lens 16b held on the upper semi-spindle 55 at its concave surface. The pivotable holder 35 is then folded in the direction of rotation D so that the suction cup/gripper 34a can be moved under the upper spindle half 35 of the workpiece spindle or the one-piece spindle housing 53. The lens 16a to be processed is picked up by the upper semi-spindle 55 while maintaining alignment and then released from the suction cup/gripper 34 a.

The carriage 33 is now removed and the finished treated lens 16b is transported back to the measuring area 10a of the apparatus 1, 1', 1 "', 1" ", according to the invention, preferably again through the opening 11a, 11b in the separating wall 11 as described above.

The lower spindle half 56 of the integrated spindle housing 53 is moved upward so that the lens 16a to be processed is fixed in its predetermined orientation and edge processing can begin.

Preferably, simultaneously during these operations, the other lens 16a is held in a spindle housing 53 located in the finishing zone 52 of the edge-processing device 50 and finished. In this process, the tool spindle 63 may already be moved upwards before transferring the lens 16a to the finishing zone 52 in order to keep the processing time as short as possible. The finishing of the lens 16a to be treated generally takes longer than its roughing.

Conveniently, the number and/or design and/or sequence of tools 62 is chosen in such a way that the edge treatment of the lens 16a to be treated can be carried out in the most time-saving manner. Since the tools 62 have feed paths of different lengths along the y-axis, the respective sequences or arrangements in the holders 64 may result in an overall minimum travel path for the holders 64, which in turn may shorten processing time.

In the starting position of the carriage 33 in the measuring area 10a of the device 1, 1', 1 "', 1" ", according to the invention, the handling unit 20a grasps the finished processed lens 16b, which is held on the concave side by the suction cup/gripper 35a, from the suction cup/gripper 35a, removes the lens 16b from the suction cup/gripper 35a and places it in the transport bin 13 assigned to it. Immediately thereafter, another measured and aligned lens 16a to be processed is transferred to the suction cup/gripper 34a, which now grips the lens 16a on the concave side while maintaining its alignment.

As mentioned above, this further lens 16a is now transferred to the treatment area 10b of the apparatus 1, 1', 1 "', 1" ", according to the invention.

At the same time, the edge treatment of the lens 16b, which has been located in the finishing zone 52 of the treatment device 50 at the same time, has been completed.

By rotating the integrated spindle housing 53, the finished processed lens 16b is transferred to the rough processing area 51 of the processing apparatus 50, and the lens 16a which has been subjected to the finishing pretreatment as described above is transferred to the fine processing area 52.

While finishing the lens 16a is started, the finished processed lens 16b is waiting to be picked up by the carriage 33, as described above. The described cycle starts again.

Thus, all measuring devices 40, 110 can be equipped with the lens 160 to be measured or the lens 16a to be treated in any order.

Likewise, each conveyor 30a, 30b may be loaded with measured and aligned lenses 16a to be processed in any order.

On the basis of production data and/or frame data of the lenses 16a to be processed, which may have been read out by the reading device 19 and transmitted to the control system or storage of the apparatus 1, 1', 1 "', 1" ", the control system thus preferably calculates the order in which the lenses 16a are processed and the selection of the respective measuring device 40, 110 and the respective conveying device 30a, 30b and the respective processing device 50 for each individual lens 16a to be processed. The calculation is carried out in particular in such a way that an optimum time sequence of the measurement, transport and edge treatment of the individual lenses to be treated is achieved, in particular with a latency that is as short as possible.

The control system or monitoring device suitable for the method according to the invention is in particular able to manage the treatment status of the lens 16a to be treated.

The measurement and processing steps required for each lens 16a are preferably defined in a so-called processing plan.

If multiple measuring devices 40, 110 and/or multiple processing devices 50 are provided, it is preferred that each lens 16a is free to select the particular measuring device 40, 110 and/or processing device 50 to be used, i.e., independent of any other measuring device 40, 110 and/or processing device 50 currently in use.

In this way, the basic sequence "measure-rough-finish" for each lens 16a remains unchanged.

The actual processing conditions for each lens 16a are reflected in the processing state. The treatment status indicates, for example, a measurement or treatment that has been performed or is to be performed next, wherein particularly preferably is performed with reference to a respective treatment plan for each lens 16 a.

The control system or monitoring device suitable for the method according to the invention is also preferably adapted to manage for each lens 16a its individual measurement time in the measurement device 40, 110 and individual processing time in the processing device 50 and/or to determine the occupancy time for each measurement device 40, 110 and processing device 50, i.e. the time period during which the respective measurement device 40, 110 and the respective processing device 50 are blocked by the relevant lens 16 a.

Based on this, the control system or monitoring device can determine the order of measurement and processing of the lens 16 a. On the one hand, the determination is preferably such that the measuring means 40, 110 and the processing means 50 can be operated as free of dead time as possible. On the other hand, it is particularly preferred to determine the order of measurement and processing of the lenses 16a independently of the order in which their respective transport boxes are arranged on the buffer belts 17a, 17 b.

In particular, with such a control system or monitoring device, the handling device or handling arrangement 20 and the transport devices 30a, 30b can be operated in such a way that the two measuring devices 40, 110 are controlled independently of one another, loaded with the lens to be measured and unloaded from the measured lens, according to the above-described exemplary embodiment of the method of the invention.

In a comparable manner, the two processing devices 50 can be controlled independently of one another, loaded with lenses 16a to be processed or unloaded from lenses 16b which have already been edge-processed.

Thus, according to the invention, the measurement and the edging of the lens 16a to be treated can be carried out in such a way that the lens 16a to be treated can be optimally assigned to the measuring device 40 and the treatment device 50, respectively, in a simple and complex manner, so that the lens 16a to be treated can be measured and edged, respectively, with the least possible expenditure of time or loss of time.

For this purpose, the control system of the device according to the invention has available corresponding production data or frame data of the lens 16a to be processed. The handling device or handling apparatus 20 and/or the transport devices 30a, 30b can thus be controlled such that the lens 16a to be processed is optimally assigned to the free measuring device 40 and/or transport device 30a, 30b and/or processing device 50 in order to achieve a measurement and/or edge processing that is as time-saving as possible.

When the respective transport box 13 enters the machine, as described above, the lens data required for this purpose, for example processing data, processing plans, processing sequences, processing steps, optical data and/or geometric data, are stored in the control system or monitoring device by means of a storage medium and/or read out from the data carrier 13 a.

Thus, the recording of the respective treatment status of the individual lenses 16a, 16b located in the device according to the invention serves to control, coordinate and organize the sequence of the individual measurement and treatment processes in the individual measuring devices 40, 110 and the treatment device 50.

These process states may alternatively or additionally be transmitted to an external monitoring system or control center, stored and/or displayed to an operator. Thus, for example, for each individual lens 16a, 16b, the following may be recorded and stored: in which measuring device 40, 110 it is measured, and in which processing device 50 it is processed. Such data acquisition may be particularly useful for troubleshooting and/or error correction if the completed lens 16b does not correspond to the production data and/or frame data assigned thereto.

In a comparable manner, however, the respective operating states of the buffer 17, the control device or control apparatus 20, the measuring devices 40, 110, the conveying devices 30a, 30b and/or the processing device 50 can also be transmitted to such a monitoring system, stored and/or displayed to an operator. "on", "off", "ready", "waiting for lens", "processing lens", "ready to deliver lens", "number of movements", "number of lenses measured", "number of lenses processed", "down time", "required maintenance", "required tool change", "failure", etc. may be defined as an operational state, as required by the specific situation. In this way, in particular, the condition, use and effective operation of the device according to the invention can be checked particularly easily and, if necessary, measures can be taken appropriately, such as tool changes, repairs, optimization of the time sequence, etc.

Tables 1 and 2 below, in conjunction with fig. 15, show an exemplary time schedule of the process according to the invention in the apparatus according to the invention as a whole (table 1) and for each individual process (table 2). In each case, time is in seconds.

In particular, FIG. 15 represents a graphical representation or rendition of operations 1a-6g listed in Table 1. As an example, fig. 15 shows a process performed simultaneously in two stations, and the stations "station 1" and "station 2" designated in fig. 15 correspond to two processing apparatuses 50, in particular, processing apparatuses having the same structure.
