Technical Field

The invention relates to a method for feeding sleeves to a winding station of a textile machine, wherein the sleeves are arranged in a rotatably mounted frame and are fed to a transport device which transports the sleeves to the winding station. The invention also relates to a device for feeding sleeves to a winding station of a textile machine, comprising at least one frame arranged rotatably about at least one vertical axis and a conveyor device associated with each machine side. The invention also relates to a textile machine with a plurality of winding stations.

Background

Modern textile machines for preparing or rewinding yarns generally have a large number of winding stations for winding the yarn, which can operate independently of one another. It is known to wind yarns onto sleeves made of, for example, cardboard. During operation, each winding station is equipped with a corresponding sleeve, so that it must be taken from time to pay attention to the feeding of certain sleeves having a certain orientation to the winding station. Furthermore, the workstations or winding stations of modern textile machines are generally juxtaposed in long rows along the two long sides of the textile machine. The above-mentioned supply of the sleeves to the winding stations is difficult to handle manually due to the large number of stations, so that it is necessary to feed the sleeves automatically to the winding stations of the textile machine.

For this purpose, for example, DE 3536818 a1 proposes a method and an apparatus for carrying out the method, in which casing strings made of nested conical casings are held on a rotary table, and the individual casings are subsequently brought into a horizontal conveying position and conveyed via a conveying device and a conveyor belt to a spooling station.

The disadvantage here is that the method can only be applied to tapered sleeves, which must first be brought into the transfer position, and that no solution is described for efficiently supplying the winder stations on the respective machine side of the textile machine.

Disclosure of Invention

In view of the above, it is an object of the present invention to propose a method and an apparatus which improve the prior art in these respects.

The solution of the invention to achieve the above object consists in a method, an apparatus and a textile machine having the features described in the independent claims.

In the method according to the invention for feeding sleeves to a winding station of a textile machine, the sleeves are arranged with a substantially horizontal longitudinal axis in a sleeve magazine of a rotatably mounted frame. The sleeves are selectively assigned to the machine side of the textile machine by means of a rotating frame.

Due to the substantially horizontal position of the longitudinal axis of the casing, the method can also be applied to casing shapes that are not absolutely conical and may not be in a nested form. For example, the sleeve may have a cylindrical shape. There is no need to provide any additional mechanism or mechanism to bring the sleeve from a vertical position to a horizontal position. Furthermore, an efficient supply to the respective machine side of the textile machine can be ensured by the rotating frame.

The textile machine may in particular be a spinning machine or a winder, wherein the spinning machine is able to work in particular according to a rotor jet spinning process or a ring spinning process. In principle, it is conceivable for the individual work stations of the textile machine to comprise a spinning station and a winding station, wherein the spinning stations can generally also be operated according to different spinning processes.

In the method according to the invention, the casing can be stacked, for example, loosely one above the other in a plurality of casing magazines and stored in this way. However, it is also conceivable to move the cannula in the cannula magazine by means of a corresponding cannula transport mechanism and to perform the filling preferably continuously. In each cannula magazine, different types of cannula can be held, for example cannulas made of different materials or in different shapes. The cannulas in the cannula cartridge are for example arranged in the same horizontal orientation. In particular, two transfer devices can be provided, via which the sleeves are passed to two conveying devices, for example conveyor belts, from which the sleeves are conveyed further to the respective winding stations. In particular, the transfer device and the transport device are each assigned to the machine side of the textile machine.

Advantageously, the rotation of the frame is actuated upon request of the winding station. For example, a spooling station requiring a casing reports the demand to a control system which has, inter alia, information about the casing stored in the casing magazine, for example its nature and/or orientation. The control system selects a sleeve magazine with matching sleeves and causes the frame to rotate to move the sleeve magazine to the machine side transfer device of the requesting winder station.

The rotation of the frame can be caused by a drive, in particular an electric motor, wherein the drive is in turn controlled, in particular by a control system. The control system may be the control system described hereinbefore and/or an independent or central control system of the textile machine.

It is also advantageous for the method to detect the orientation and/or the properties of the bushing before the attachment to the machine side. As previously mentioned, it is important for each winding station to obtain a qualitative and/or oriented bushing according to the requirements. In this regard, the detection may serve as a basis for rotating the frame and releasing the corresponding machine-side casing. For example, when filling a cannula cartridge, a corresponding check may be performed. It is also conceivable, however, to carry out the detection of the winding station as required. To this end, the frame or cannula cartridge advantageously has sensors configured to detect the properties and/or orientation of the cannula.

It is also advantageous that the sleeve is released by a release mechanism and moved from the frame to the transfer device via a transfer device. This process is particularly followed by the rotation of the frame. In this way, the sleeves can be distributed individually to the winding station, for example, as required. To this end, the cannula is preferably further delivered by the delivery device as described above after it has passed the transfer device. The release mechanism may for example be a flap, in particular at the lower end of the cannula cartridge, from which the cannula is delivered under the influence of gravity when the release mechanism is activated. To this end, the release mechanism may have a drive and be controlled by a control system. The cannula may be passed passively or actively through the transfer device. For example, the transfer device may include an inclined plane on which the cannula rolls to the delivery device. However, it is also conceivable for the transfer device to be designed, for example, as a pivotable transfer disk or as a movable gripper.

According to the invention, a device for feeding sleeves to a winding station of a textile machine is also proposed, which comprises at least one frame arranged so as to be rotatable about at least one vertical axis and a conveyor device associated with each machine side. The apparatus is characterized in that a plurality of cannula magazines are arranged on the outer circumference of the frame, which are configured to accommodate cannulas with a longitudinal axis arranged substantially horizontally. The apparatus is particularly suitable for performing the above method. Accordingly, the apparatus also relates to the advantages already described with respect to the above-described method. The device is thus also capable of holding a non-tapered sleeve and efficiently feeding the sleeve to the winding stations on the respective machine side of the textile machine. The conveying device can be designed in particular as a conveyor belt.

In an advantageous development of the device, the floor of the frame has the shape of a regular polygon. The vertical axis of the frame is preferably located at the center of the polygon. The shape has a defined number of edges, on which in particular the cannula cartridge can advantageously be arranged. Conceivable shapes include, for example, pentagons, hexagons, heptagons and octagons. In this case, it is conceivable to allow only a stepwise rotation of the frame, wherein the rotation step corresponds to the central angle of the two adjacent angles of the polygon. Multiple vertical axes, for example two, may also be provided. In this case, the sides of the polygon are, for example, elliptically arranged relative to one another.

It is advantageous for the apparatus that the cartridge has an opening at its lower end for dispensing the cannula. Gravity may be used to dispense the cannula with the opening at the lower end. This eliminates the need for additional means for transporting the cannula. The opening for the dispensing cannula may be arranged in a side or bottom surface of the cannula cartridge. If these openings are arranged in the side face, they are preferably located on the side of the cannula cartridge facing away from the vertical axis or the axis of rotation of the frame. The opening size preferably substantially corresponds to the cannula size or a two-dimensional projection of the cannula size.

It is further advantageous that the cannula magazine has an opening at its upper end for receiving a cannula. This also enables gravity to be used to receive or fill the cannula. The opening for receiving the cannula is preferably located in the top side of the cannula cartridge. The filling can be carried out manually or automatically, wherein a cannula cassette and/or a device for refilling the cannula magazine can be arranged above the cannula magazine.

The size of the opening for receiving the cannula also preferably substantially corresponds to the cannula size or the two-dimensional projection of the cannula size.

It is also advantageous if the cannula magazines each have a cannula-conveying mechanism. The cannula transport mechanism facilitates controlled movement of the cannula within the cannula cartridge and can improve the throughput of the cannula through the cannula cartridge. The jacket transport mechanism can be configured, for example, as an endless conveyor belt with a separate jacket holder, similar to a bucket elevator.

It is also advantageous if at least one opening for the dispensing sleeve is provided with at least one limiting element. The opening for the dispensing sleeve is preferably closed by at least one restriction element. This ensures that the sleeves leave the sleeve magazine only when needed and in particular one by one. The limiting element can be configured, for example, as a separate flap, for example at each cannula cartridge. It is also conceivable that the limiting element is a wall surrounding the frame. The essential function of the restriction element is to prevent the cannula from leaving the cannula cartridge uncontrolled. Thus, the restriction element need not necessarily have a continuous surface; separate pins or grids are also envisaged.

It is advantageous for dispensing the separate sleeve that the at least one restriction element has at least one release mechanism. As already mentioned, the release mechanism can be configured, for example, as a flap mechanism which releases the passage of the respective sleeve, in particular in the direction of the corresponding transport device, as required.

It is also advantageous if the apparatus has a transfer device between the frame and the conveying device. The transfer device is able to ensure that the cannula is transferred from the cannula cartridge to the delivery device in a controlled manner. The transfer device may be a passive device, e.g. in the form of an inclined plane or ramp, or an active device, e.g. in the form of a pivotable transfer disc or a gripper.

It is advantageous to ensure that the cannulas reach the region of the delivery devices in a controlled manner that the delivery devices are each provided with a cannula stop, which is arranged in particular opposite the respective transfer device. If the sleeves roll or slide on a transfer device in the form of an inclined plane, the sleeve stops serve to brake the sleeves so that they first rest on a transport device in the form of, for example, a conveyor belt. The sleeve stop can be configured, for example, as a rim or wall.

It is additionally advantageous if the device has at least one means for detecting the orientation and/or the properties of the cannula. As mentioned above, the winder stations of the textile machine may optionally have sleeves of different properties and/or orientations. Correspondingly advantageous for being able to feed the correct sleeve to the winding station is the measurement of the sleeve, for example by means of a sensor. The sensor may in particular be an optical sensor. In general, the means for detecting the cannula orientation and/or the cannula properties may for example be arranged within the cannula cartridge or as an integral part of the transfer device. It is also conceivable that the mechanism is an integral part of the device for refilling the casing magazine.

The frame is advantageously arranged centrally between the machine sides in order to ensure as efficient a supply as possible to the respective machine side. Furthermore, the length and width of the sleeve magazine correspond in particular substantially to the diameter of the floor and the height of the sleeves.

According to the invention, a textile machine with a plurality of winding stations is proposed, which is characterized in that it has a device according to the preceding description. Accordingly, the textile machine according to the invention is also suitable for carrying out the method according to the invention. This has the advantage that the winding stations of the textile machine can be supplied with sleeves efficiently and substantially automatically. As mentioned above, the textile machine may be a spinning machine or a winder, wherein the winder stations are preferably juxtaposed to each other along both longitudinal machine sides of the textile machine. The device can be arranged, for example, on the top side of the textile machine.

It is also conceivable for the textile machine to have a plurality of devices, for example at the respective front end of the textile machine. The driven element of the device may be connected to a central machine control system, wherein the element is controlled by the central machine control system.

Detailed Description

In the following detailed description, the same reference numerals are used in the different figures for identical and/or at least equivalent features. Individual features, their design and/or mode of operation are usually described in detail only when first mentioned. If individual features are not specified again, their design and/or mode of action correspond to the design and mode of action of the equivalent or comparable features already described.

Fig. 1 shows a textile machine 1 with a spooling station 3 arranged on two machine sides 2. On the top side 4 of the textile machine 1, a device 5 according to the invention for feeding a sleeve 6 to the winding station 3 is arranged. Centrally arranged between the machine sides 2 is a frame 8 (see fig. 2) which is rotatably mounted about a vertical axis 7. A plurality of cannula magazines 10 are in turn arranged on the outer periphery 9 of the frame 8, these cannula magazines 10 containing the cannulae 6 with their longitudinal axes 11 arranged substantially horizontally (see fig. 4). In this embodiment, the cannulas 6 are loosely stacked one on top of the other in the cannula magazine 10.

At the respective upper end 13 of the cannula magazine 10 (see fig. 4), the cannula 6 can be refilled through an opening 12 for receiving the cannula 6. At the lower end 14 (see fig. 4) of the cannula cartridge 10 there is an opening 15 for the dispensing cannula 6, which opening 15 is provided with a restriction element 16. In this case, the restriction element 16 is a flap which can be opened by a release mechanism 17 (see fig. 4) if the cannula 6 is to be dispensed from the cannula cartridge 10.

The device 5 also comprises two conveying devices 18, which are each assigned to the machine side 2. The conveyor 18 can be designed, for example, as a conveyor belt. Between the frame 8 and the conveyor 18, a transfer device 19 is arranged, which transfer device 19 is constructed in the present embodiment as an inclined plane on which the sleeves 6 can be rolled to the conveyor 18. In order to initially stop the sleeve 6 on the transfer device 18, the transfer device 18 is provided with sleeve stops 20, which sleeve stops 20 are each located opposite the transfer device 19.

By rotating the frame 8, some cannula magazines 10 can be moved to the transfer device 19, so that the lowermost cannula 6 in the respective cannula magazine 10 can be dispensed to the respective transfer device 18. This process can be triggered, for example, upon request of the winder station 3. The transport device 18 can transport the sleeves 6 further along the respective machine side 2 to the corresponding winding station 3.

The cannulas 6 may be individually retained in each cannula cartridge 10, for example, depending on their nature and/or orientation. On the other hand, it is also conceivable to hold the sleeves 6 without a specific order.

Fig. 2 shows a top view of a textile machine 1 with a device 5 according to an embodiment of the invention, which device 5 is similar to the device shown in fig. 1. Two conveyors 18 are arranged on the respective machine side 2. In this plan view, it can be seen particularly clearly that the bottom face 21 of the frame 8 has the shape of a regular polygon. In the present embodiment, the bottom surface 21 has an octagonal shape. The present embodiment differs from the embodiment shown in fig. 1 in that the opening 15 of the cartridge magazine 10 for the dispensing cartridge 6 is provided with a common limiting element 16. The limiting element 16 is designed as a circumferential wall and has two release mechanisms 17 in the region of the transfer device 19. The release mechanism 17 can be configured, for example, as a flap.

The height of the restriction element 16 preferably corresponds to the height of the opening 15 of the cannula cartridge 10 for the dispensing cannula 6. However, it is also conceivable for the height of the limiting element 16 to correspond to the height of the cannula cartridge 10. In this case, it is conceivable that the individual cannula cartridges 10 do not have their own walls on the sides of the restriction element 16. This saves material costs.

An embodiment of the apparatus 5 is shown in fig. 3, illustrating an alternative arrangement of the cannula cartridge 10 on the frame 8. As shown, the longitudinal axis 11 of the cannula 6 in the cannula cartridge 10 is radially outward from the vertical axis 7 or from the bottom surface 21 of the frame 8. By this arrangement, a greater number of cannula magazines 10 can be arranged on the frame 8 with similar space requirements. In this case, compared to the previous embodiments, an opening 15 for the dispensing cannula 6, a restriction element 16 and possibly a release mechanism 17 are preferably provided on the end face of the cannula cartridge 10. When dispensing the cannulas 6 from the cannula magazine 10, these cannulas 6 slide, for example, past the transfer means 19 in this case.

Fig. 4 shows an example of a single casing magazine 10 of the apparatus 5 according to the invention. The present figure is intended to illustrate the way in which the cannula 6 is arranged in the cannula cartridge 10 with a longitudinal axis 11 arranged substantially horizontally. The sleeves 6 are loosely stacked one above the other. At the upper end 13 of the cannula cartridge 10 an opening 12 is arranged for receiving the cannula 6. Also arranged in this area is a mechanism 22 for detecting the orientation and/or properties of the cannula. For example, the means 22 for detecting the cannula orientation and/or the cannula properties can be configured as a sensor, in particular as an optical sensor. The means 22 for detecting the cannula orientation and/or the cannula properties can of course also be arranged in other areas of the cannula cartridge 10 and/or the device 5.

At the lower end 14 of the cartridge 10 an opening 15 for dispensing the cartridge 6 is arranged. The limiting element 16, for example in the form of a pin, prevents the cannula 6 from leaving the cannula magazine 10.

These pins can be set down by a release mechanism 17, thereby releasing the dispensing opening 15, and preferably the single cannula 6 can be moved out of the cannula magazine 10. For this purpose, the underside of the cartridge 10 advantageously has a slope. The length and width of the cannula magazine 10 preferably substantially correspond to the horizontal two-dimensional projection of the dimensions of the cannula 6.

Fig. 5 likewise shows the cannula cartridge 10 of the device 5 according to the invention. In this example, the magazine 10 has a cannula-conveying mechanism 23 in the form of a bucket-chain endless belt. The endless belt has individual sleeve holders in which the sleeves 6 are arranged. It is contemplated that the opening 12 for receiving the cannula 6 may be provided at the lower end 14 of the cannula cartridge 10. With the cannula-conveying mechanism 23, the throughput of the cannula 6 can be increased. It is conceivable to continuously refill the cannula 6 into the cannula magazine 10. The cannula delivery mechanism 23 shown can of course be combined with the previously described embodiments.

Fig. 6 shows another example of a device 5 according to the invention. The construction of the device 5 is similar to that of fig. 2, the key difference being that the device 5 in this case has two frames 8, both frames 8 being rotatably mounted about a vertical axis 7. The cannula cartridge 10 is arranged on the outer circumference 9 of the frame 8, wherein the cannula cartridge 10 is not fixedly connected to the frame 8. In the present embodiment, the casing magazines 10 are transported along the restriction elements 16 of oval configuration by rotating the frame 8, so that the casing magazines 10 on the frame 8 are turned and transported to the respectively opposite machine side 2. It is envisaged that the cannula cartridge 10 is urged by rotation of the frame 8. On the other hand, the cartridge 10 can also be connected to an endless element, such as a conveyor belt or a conveyor chain. The advantage of this embodiment is that the number of cannula magazines 10 is increased and the capacity of the cannula 6 associated therewith is increased.

The invention is not limited to the embodiments shown in the drawings and described herein. Combinations of features shown and described in different embodiments are equally possible within the scope of the claims.
