Technical Field

The invention relates to a method for supplying bobbins (H ü ls) to one side of a double-sided textile machine, in particular a spinning machine, having a plurality of workstations arranged in the longitudinal direction of the textile machine, and a second and a third transport device, wherein the textile machine corresponds to a first transport device which is located after the workstations in the longitudinal direction of the textile machine, the second and third transport devices being arranged along the workstations on opposite sides of the textile machine.

The invention also relates to a device for supplying bobbins to one side of a double-sided textile machine, in particular a spinning machine, having a plurality of workstations arranged in the longitudinal direction of the textile machine, and a second and a third transport device, wherein the textile machine corresponds to a first transport device which is located after the workstations in the longitudinal direction of the textile machine, the second and third transport devices being arranged along the workstations on opposite sides of the textile machine.

Background

Textile machines that produce or process yarns (e.g., spinning or winding machines) typically wind the produced or processed yarn on a carrier (e.g., an empty tube composed of plastic or cardboard). Modern textile machines generally have a plurality of stations which operate at least partially independently of one another, wherein each of these stations requires the periodic replacement of a fully wound reel with an empty tube. As is known, the stations are arranged side by side on both sides of the textile machine.

For example, an automatic conveying system is known from DE 4344058a1, which is arranged above the textile machine and is composed primarily of endless conveying members which circulate. Receptacles for empty tubes and cross-wound spool carrying elements (kreuzdustentwinement) are provided on this endless conveying member.

A problem with known transport systems is that the potential independence of the individual stations causes empty tubes of different nature to be required at different locations on the textile machine. Here, it is known practice to provide empty tubes with one or several cartridge magazines. Furthermore, the number of individual stations is sometimes so large that the transfer system must work quickly and efficiently to avoid unnecessary downtime of the stations.

Disclosure of Invention

In view of the above, the object of the present invention is to propose a method and a device whereby both can efficiently transfer bobbins from one or several bobbin magazines to respective stations on different sides of a textile machine.

To achieve the above and other related objects, the present invention provides a method of providing bobbins for one side of a double-sided textile machine, in particular a spinning machine, having a plurality of stations arranged in a longitudinal direction of the textile machine and second and third transfer devices, wherein the textile machine corresponds to a first transfer device located after the stations in the longitudinal direction of the textile machine, the second and third transfer devices being arranged along the stations on opposite sides of the textile machine, bobbins located on the first transfer device being selectively assigned to the second or third transfer device by an assignment device.

The method of the present invention may deliver the bobbin tube by the dispensing device establishing the shortest connection between the origin and the target point. The target point is the station where a particular bobbin is required. The different transport means may operate partly independently of each other. This allows the operating speed of the individual conveying means or distribution means to be adjusted according to the urgency and the energy requirement. The first transfer device is preferably automatically supplied with bobbins.

The transfer means and the distribution means can be activated only when needed for energy saving purposes. Alternatively, it is also possible to run the conveyor continuously and/or to move the dispensing device to the neutral initial position after each dispensing operation.

The transfer device can be constructed as a conveyor belt, in which the bobbins are transferred, for example, lying on their back. In this process, the bobbins are advantageously guided by side walls on both sides of the conveyor belt, in order to prevent the bobbins from falling off. The dispensing device can be constructed, for example, as an adapter (Weiche) or as an adjustable guide element.

Of course, it is also possible to provide a conveying device with, for example, a receptacle for an empty pipe.

Particularly advantageous for the process are: the bobbins are supplied to the first transfer device from at least one bobbin magazine arranged on at least one side of the first transfer device, preferably several bobbin magazines arranged on both sides of the first transfer device. In the case of the bobbin magazines known per se, a large number of bobbins can be stored, so that manual intervention by an operator is only occasionally required.

It is possible to stock bobbins of different shapes which are reliably delivered to the desired position by the dispensing device during the method. In the case of two bobbin magazines, only one type of bobbin can be stored in each bobbin magazine, but it is also possible to store different types of bobbins in each bobbin magazine. In this case, the following is advantageous: the nature and/or orientation of the bobbin is detected during the transfer, for example with a scanner or camera, in order to ensure that the correct bobbin is supplied to the station, in particular in the correct orientation.

It is further advantageous that: rotating the bobbin prior to dispensing to the second or third transfer device. The bobbin may need to arrive at the destination in a particular orientation according to the instructions of the station. By rotating the bobbin tubes as appropriate before dispensing, only one central device for rotating the bobbin tubes needs to be provided, which can reduce the costs of the respective conveying system.

The bobbin may already be rotated when being supplied to the first transfer device. Furthermore, the bobbin may be rotated during the assignment to the second or third transfer device. In particular, this rotation may be triggered by the detection of the nature and/or orientation of the bobbin tube as described above.

The following facilitates further automation of the method: the control device operates the distribution device according to the instructions of the work stations. Wherein the stations can be instructed early before the last reel is full, so that the cartridge arrives at the respective station on time.

The command is advantageously in turn sent from the control device of the workstation itself to the control device of the dispensing device. The commands of the individual workstations can be managed, for example, by a central control unit of the textile machine, or the central control unit can determine the sequence of these commands.

The invention relates to a device for supplying bobbins to one side of a double-sided textile machine, in particular a spinning machine, having a plurality of workstations arranged in the longitudinal direction of the textile machine, comprising a first transport device which is located downstream of the workstations in the longitudinal direction of the textile machine. The device also has a second and a third conveyor arranged along stations on opposite sides of the textile machine. For the device, the invention proposes: the first transfer device corresponds to a dispensing device that selectively dispenses spools to the second transfer device or the third transfer device.

The device according to the invention makes it possible to supply the workstations with bobbins in an efficient manner, since the bobbins do not have to travel any additional distance. At the same time, the device is of a relatively simple construction and is therefore inexpensive. The dispensing device can dispense bobbins of different nature supplied to the first transfer device to both sides of the machine. The respective bobbin is then transported by the second or third conveyor to the station where a change is required.

The transfer means and the dispensing means may take many different embodiments. Decisive is the ability of the dispensing device to selectively dispense a bobbin from the first transfer device to the second or third transfer device. For this purpose, the dispensing device can move the bobbin, for example, perpendicularly to the direction of movement of the conveying device.

The dispensing device may be an integral part of the first conveying device. Furthermore, it may be advantageous to drive and control the conveying means and the dispensing means individually and as appropriate. For example, the transfer device and the dispensing device may each have their own motor. Of course, it is also possible to drive all or individual components, for example pneumatically or hydraulically.

The distribution device can be constructed, for example, as an adjustable guide element, a rotatable platform, a gripper arm, a transfer slide, a compressed air fan, a slide or an additional transfer device which can have two orthogonal directions of movement.

The device is advantageously arranged on the top side of the textile machine. This does not damage the components of the textile machine that make or process the yarn. Furthermore, the ceiling height of the industrial building in which the respective textile machine is operated is usually sufficiently large.

In addition to the above-described embodiments of the dispensing device, the following are also particularly advantageous: the dispensing device is an adapter. The adapter is a channel changing component which is tested for a long time in the material conveying technology. There are many different adaptor embodiments that comply with the dispensing device instructions. For example, the dispensing device may be constructed as a sliding adapter, a rotary adapter or a drag adapter.

Furthermore, advantageous to the device of the invention are: the distribution device is disposed between the first and second conveyors and the third conveyor. In this way, the dispensing device is able to optimally perform the function of dispensing the bobbin to the second or third transfer device.

The distribution device can also be arranged at least partially beside one or several conveying devices or in a plane overlapping the conveying devices. As described below, the following may also be advantageous: the dispensing device is at least partially disposed above the second conveyor and the third conveyor. In some embodiments, the following are advantageous: the distribution device establishes a connection of the end region of the first transport device with the end regions of the second and third transport devices, or a connection of the end region of the first transport device with the end regions of the second and third transport devices can be established by means of the distribution device.

Another advantageous development of the invention is: the first conveyor, the second conveyor, and/or the third conveyor are conveyor belts. Conveyor belts are another long experienced material handling tool. The conveyor belt is reliable and low maintenance. The bobbins may be conveyed, for example, lying flat on a conveyor belt. The conveyor belt may also have receptacles for bobbins or other single holders. The conveyor belt or belts may advantageously be operated at variable speeds. The conveyor belt or belts may also have side walls that prevent the bobbins from falling. The conveyor belt or belts may be driven individually, may have independent controllers as appropriate and may operate continuously or only when required. The conveyor belt or belts may also be controlled by a controller common to the dispensing device. Furthermore, the conveyor belt can also be a component of the distribution device.

It is advantageous that: the first conveyor is at least partially disposed above the second conveyor and the third conveyor. By means of the height difference between the first, second and third conveyors in such an arrangement, the distribution device can advantageously make use of gravity. In this way, the bobbin tube, for example, only has to fall in the correct direction from the first conveyor and land on the second or third conveyor. The bobbin tube can be guided here, for example, by one or several slides or inclined planes.

In order to be able to automatically supply bobbins to the first transport device in an efficient manner, the following are advantageous: the first transport device corresponds at least on one side, preferably on both sides, to at least one bobbin magazine for supplying bobbins to the first transport device. The stocking of bobbins in the magazine also has the advantage of requiring less manual intervention, which offers the potential to reduce the running costs of the textile machine.

The first conveying device can also correspond only or further to the cartridge magazine on the end side of the textile machine.

It is further advantageous that: the first transfer device corresponds to a rotating device for rotating the bobbin. This is advantageous mainly in the following cases: the bobbins must have a certain orientation at the station, which may not have been established while in the magazine. The rotating device may be an integral part of the first conveying device or the dispensing device. For example, the rotary adapter may perform the functions of both the dispensing device and the rotating device.

In order to determine the orientation of the bobbin, as previously mentioned, the following are advantageous: the device has means for determining the orientation and/or properties of the bobbin, such as a scanner or camera. This prevents the wrong tube or the tube with the wrong orientation from being transferred to the working position. The member may also be used to control the rotating means.

Furthermore, the following is advantageous: the distribution means corresponds to control means. The control device is responsible for controlling the dispensing device as needed and for the dispensing device to function accurately. As mentioned before, the control device may also be used to control one or several transport devices. The control means may for example be an integrated circuit or a computer. The controller may also be integrated in the drive of the dispensing device.

Particularly advantageous are: the control device is connected to a superordinate controller, in particular a station controller or a machine controller. Specifically, the control device may be connected to all the station controllers, and may be connected to the machine controller as appropriate. The machine controller may also assume the role of a control device. The control means may control the dispensing means and the transfer means as appropriate based on instructions from the stations and/or the sequence determined by the machine controller.

In a further advantageous development of the device, two first conveyors are provided, wherein one of the first conveyors corresponds to each side of the machine. This is advantageous, in particular, if a cartridge magazine is provided on each side of the machine, since then the bobbins can be transferred from a first transfer device to the dispensing device in each case. Each first transfer device may correspond to one cartridge magazine. Here, the dispensing device must be able to dispense the bobbins coming from the two first conveyors to the second or third conveyor. For this purpose, it may be advantageous to provide a multi-stage distribution device.

Detailed Description

In the following description of the figures, the same reference numerals are used for the same and/or at least similar features illustrated in different figures. The features and their technical solutions and/or operating principles are usually only explained in detail when first mentioned. If these features are not described in detail again, the technical solutions and/or the operating principles thereof are equivalent to those of the features with the same functions or names and described above.

As shown in fig. 1, textile machine 1 has a plurality of work stations 2, which are arranged side by side in longitudinal direction 3 on a side 4 of textile machine 1. The textile machine 1 can be a spinning machine or a winding machine, in which case the stations 2 make or rewind the yarn independently of each other, wherein the yarn is wound on a reel 5. In order to ensure a substantially uninterrupted working process, the reel 5 at the station 2 must be replaced periodically with a bobbin 6. For this purpose, the station 2 must be reliably supplied with bobbins 6. Textile machine 1 has on its top side 7 a device 8 for supplying bobbin 6 to workstation 2. From the bobbin magazine 9 the bobbins 6 are transferred by the first transfer device 10 to the dispensing device 11. The dispensing device 11 is used to selectively dispense the bobbins 6 to the second transfer device 12 or the third transfer device 13, from which the bobbins 6 are further transferred to the stations 2 on the different sides 4 of the textile machine 1.

The conveyors 10, 12, 13 are designed as conveyor belts, for example, on which the bobbins 6 are conveyed lying. The conveyors 10, 12, 13 can be driven in particular independently of one another. The transport devices 10, 12, 13 transport the bobbins 6 in the longitudinal direction 3 of the textile machine 1.

The distribution device 11 is constructed in the present embodiment as a pivotable conveyor belt which is preferably pivotable between two positions, which establish a connection between the first and second conveyor 10, 12 or between the first and third conveyor 10, 13, respectively. The dispensing device 11 can also be additionally pivoted into a third neutral position located between the above-mentioned positions. Thereby reducing the time required for pivoting the dispensing cartridge 6.

The dispensing device 11 corresponds to a control device 14, which controls the dispensing device 11. The control device 14 is connected to a machine controller 15 and/or to one or several position controllers 16. The control device 14 can operate the dispensing device 11 on the basis of the commands of the stations 2. The command is in particular provided by the station controller 16 of the station 2. If a conflict arises between the instructions of different stations 2, the control device 14 or the machine controller 15 can determine the order of the instructions. The command of the station 2 is advantageously given in time before the reel 5 is full, so that the station 2 causes as little downtime as possible.

The conveyors 10, 12, 13 may be controlled by a control device 14 or a machine controller 15. The control device 14 can be integrated, for example, in a drive of the dispensing device 11. The second conveyor 12 and the third conveyor 13 can likewise be used for removing the fully wound reels 5.

Fig. 2 shows an embodiment of the device 8 according to the invention, in which the bobbins 6 are transferred from the two bobbin magazines 9 by two first transfer devices 10 to a dispensing device 11, which is designed here as a rotary adapter 18. In this case, the dispensing device 11 can also be advantageously used to turn the bobbin 6 if it is desired to have the bobbin arrive at the station 2 in a specific orientation.

The dispensing device 11 can establish a direct connection between the relevant first transfer device 10 and the second transfer device 12 or the third transfer device 13 of the opposite side 4 of the textile machine 1, by means of which connection the bobbin 6 can be transferred without interruption. When it is necessary to transfer a bobbin 6 from one of the two bobbin magazines 9 to a station 2 on the same side 4 of the textile machine 1, this bobbin 6 must be momentarily rested on the dispensing device 11, during which the dispensing device 11 is brought into the correct position. That is to say, in order to be able to rapidly dispense the bobbins 6, it may be preferable here to transfer them to the other side 4 of the textile machine 1. But the speed difference is usually negligible if it is necessary to rotate the bobbin 6. In the case where there is only one first transfer device 10, the rotary adapter 18 from the present embodiment can also be used.

Fig. 3 shows a further embodiment in which the bobbins 6 are transferred from the two bobbin magazines 9 by two first transfer devices 10 to the dispensing device 11. The dispensing device 11 is designed here as a two-way adapter 19. The advantage is that the dispensing device 11 in this case has a position in which there is a direct connection between the first transport device 10 and the second transport device 12 and the third transport device 13, respectively, on the same side 4 of the textile machine 1. In this way, it is possible to pass several bobbins 6 simultaneously through the dispensing device 11, if desired. When it is desired to transfer the bobbin 6 to the opposite side 4 of the textile machine 1, it is also only necessary to change the position of the dispensing device 11.

Fig. 4 shows a device 8 in which the bobbins 6 are transferred from the two rotating devices 17 to the dispensing device 11 by the two first transfer devices 10. The dispensing device 11 is constructed in this case as a transport slide 20. As with the rotary adapter 18, the dispensing device 11 can establish a connection between one of the first transfer devices 10 and the second transfer device 12 or the third transfer device 13 in two positions, respectively, which can be used to transfer the bobbins 6 without interruption. In this case, however, the direct connection is present between the first conveyor 10, the second conveyor 12 and the third conveyor 13 on the same side 4 of the textile machine 1. If it is desired to transfer the bobbin 6 to the opposite side 4 of the textile machine 1, the bobbin 6 has to stay on the dispensing device 11 for a certain time. One of the advantages of this embodiment is that the conveyors 10, 12, 13 do not have to be curved, thus saving manufacturing costs as appropriate.

Fig. 5 shows a device 8 in which the bobbin 6 is transferred to the dispensing device 11 by a rotating device 17 and a first transfer device 10. In this embodiment, the first conveyor 10 is arranged above the second conveyor 12 and the third conveyor 13 (see fig. 7). In this way, the distribution device 11 can make use of gravity. The dispensing device 11 has a transfer section 21 which can be tilted to one of the sides 4 of the textile machine 1 each time, wherein the bobbin 6 rolls or slides by means of a tilting plane 22 towards the second transfer device 12 or the third transfer device 13. In order to avoid the bobbins 6 falling, side walls 23 are provided in the region of the dispensing device 11 at the second conveyor 12 and the third conveyor 13. Of course, corresponding side walls 23 can be provided throughout the conveyors 10, 12, 13. In this case, curved conveyors 10, 12, 13 can also be dispensed with. Efficient allocation is also achieved with a minimum amount of motion. For example, if the bobbin 6 is moved to one of the sides 4 of the textile machine 1 by means of compressed air, the dispensing device 11 need not be moved at all.

Fig. 6 shows an embodiment of the device 8 according to the invention, in which the dispensing device 11 is formed by a chute 24 and an adjustable guide element 25. The first conveyor 10 is here also located above the second conveyor 12 and the third conveyor 13 (see fig. 7). The bobbin 6 slides towards the second conveyor 12 or the third conveyor 13 depending on the position of the guide element 25. Here too, side walls 23 are provided which brake the bobbin 6. This embodiment is of relatively simple construction, and the guide element 25 requires only a minimal movement to effect dispensing of the bobbin 6.

Fig. 7 shows a side view of a textile machine 1 with a device 8 according to the invention. As with the embodiment of fig. 5 and 6, the first conveyor 10 is located above the second conveyor 12 and the third conveyor 13 (not visible). As shown in fig. 5, the dispensing device 11 has a tiltable conveyor section 21. In the present embodiment, the bobbin 6 falls towards one of the sides 4 of the textile machine 1 on the basis of the movement of the tiltable conveying section 21, lands on the second conveying device 12 or the third conveying device 13, and is conveyed by the latter to the relevant station 2.

The invention is not limited to the above-described embodiments shown in the drawings. Modifications are also possible within the scope of the claims, for example by combining features appearing in different embodiments.
