Description

winding machine

The invention relates to a winding machine for winding a plurality of continuously running threads into bobbins according to the preamble of claim 1.

In the production of freshly spun threads, such winding machines are used in spinning systems, each of which winds up one thread with a plurality of winding positions next to one another to form a bobbin. The coils are formed on sleeves, which are placed one behind the other on a cantilevered rotatably mounted winding spindle. The winding machines can have up to ten or more winding positions next to one another, so that up to ten or more bobbins are attached and held one behind the other on a winding spindle. After the coils have reached a maximum diameter, the coils are changed. For this purpose, the bobbins are pushed off the bobbin spindle by a push-off device and taken over by a bobbin transport device. Such a winding machine is known for example from EP 0 888 243 B1.

The fully wound bobbins are removed and removed by manually operated or automated bobbin transport trolleys. For example, EP 0 757 658 B1 describes the automated removal and removal of fully wound coils. Here, a higher-level central control is provided, by means of which the processes on the bobbin transport carriage and on the winding machine can be controlled. However, such concepts are only suitable for large automated systems.

In contrast, the picking up and removal of the finished wound coils by manually operated coil transport car is widespread. Such a coil transport carriage is, for example, from DE 100 08 036 AI known. For removal and removal, the manually guided bobbin wagon is brought into an aligned position with the take-up mandrel to the winding spindle of the winding machine. The push-off device is then activated on the winding machine, so that the completely wound bobbins are pushed from the winding spindle onto the receiving diameter of the bobbin transport carriage. The bobbin transport carriage is held by the operator. After the finished wound bobbins are pushed onto the mandrel of the bobbin transport carriage, the bobbin transport carriage is guided to an unloading station.

The holding mandrel attached to the bobbin transport carriage for receiving the fully wound bobbins must therefore have a length corresponding to the bobbin spindle. In cases where 10 or more bobbins are wound side by side on a bobbin, the bobbins have lengths of 1,200 mm, 1,500 mm or> 1,500 mm. In order to take up the fully wound bobbins, the mandrels of the bobbin transport carriages must have the appropriate lengths. This poses the problem for an operator, on the one hand, of guiding the bobbin transport carriage and, on the other hand, of operating the winding machine to activate the push-off device.

It is therefore an object of the invention to carry out a winding machine of the generic type with improved operability for manual clearing and removal of the finished wound bobbins.

The object is achieved by a winding machine with the features of claim 1 and by a winding machine with the features of claim 9.

Advantageous developments of the invention are defined by the features and combinations of features of the dependent subclaims. The invention is characterized in that an operator who a

- Spool transport carriage leads into a take-up position for taking-up fully wound coils, immediately and without delay. can activate the push-off process. For this purpose, the operator can remain in their respective stopping position remote from the winding machine. According to the invention, the activation of the push-off device can be triggered by a remote-controlled switching means. There is no need to press a button on a control panel of the winding machine. The particular advantage of the invention is further that, even when the finished wound bobbins are manually cleared away and transported away, a rapid bobbin change is achieved.

To increase flexibility, the push-off device can be activated either via the switching means or via a control panel to operate the machine. This can also advantageously be used to carry out partially automated processes in which the bobbin transport wagons are positioned by automated guide systems and in which the machine is operated by an operator.

To enable the full packages in pure manual guidance of the coils trolley fast ^'and low-latency and pushing Aufiiehme, this can make the switch means in different versions. In a first particularly advantageous embodiment according to the

Development of the invention according to claim 3, the switching means by a

Switch transmitter and a switch receiver are formed, which are wirelessly connected to each other. The switch transmitter is preferably attached to the bobbin transport carriage and can be operated by the operator. The switch receiver, which is attached to the winding machine, receives the signals of the switch transmitter emitted by infrared, radio or ultrasound. The one from that

Switching signals received by switching receivers can then be forwarded directly to a control unit for activating the push-off device. However, it is also possible to design the switch transmitter as a mobile unit which is carried directly by an operator.

In a particularly advantageous development of the invention, the switch transmitter can be alternately combined with a plurality of switch receivers to activate a plurality of separate push-off devices. Usually there are several winding machines in a row next to each other. For the removal and removal of the fully wound bobbins, the bobbin transport carriage must be guided alternately to the individual winding machines by an operator. By means of coded switching signals or shielded from neighboring winding machines, the respective switching signal can be fed to the switching receiver assigned to the winding machine with a switching transmitter, without involving neighboring switching receivers. However, there is also the possibility of forming the switching means by a switching button which is arranged in the region of the free end of the winding spindle and which can be actuated in a simple manner by the operator.

A particularly advantageous development of the invention is given in that the switching means is formed by a proximity sensor which interacts with the coil transport carriage. This eliminates the need for manual operation to activate the push-off device by the operator. As soon as the operator has brought the coil transport carriage into the take-up position, the proximity sensor is activated by the coil transport carriage. The push-off process on the winding machine is triggered. Here, the proximity sensor can be designed without contact.

However, the formation of the proximity sensor as a is particularly advantageous

Contact switch, which can be actuated by the coil transport carriage in a recording position. So that the deportation process only after one mechanical coupling between the bobbin transport carriage and the winding machine.

The invention according to claim 9 is characterized in that the bobbin transport carriage is automatically held to accommodate the bobbins, so that the operator only has to position the bobbin transport carriage. In this case, the push-off device can be activated by the operator on the control panel of the winding machine. It is particularly advantageous here if the bobbin transport carriage can be locked in the take-up position by a releasable holding device, such as can be formed, for example, by a self-releasing catch in the machine frame of the winding machine.

In order not to have to interrupt the winding process during the removal of the bobbins, the spindle carrier is preferably formed by a bobbin turret on which a second cantilevered bobbin spindle is held. By rotating the winding turret, the winding spindles can alternately be guided into a removal position for the removal of the completely wound bobbins. During the removal of the completely wound bobbins, the winding process is continued on the second winding spindle located in an operating area.

The invention is explained in more detail below with the aid of a few exemplary embodiments with reference to the accompanying drawings.

They represent:

Fig. 3 schematically shows a view of a further embodiment of the winding machine according to the invention

Fig. 4 is a schematic view of another embodiment of the winding machine according to the invention. Fig. 5 schematically shows a section of a further embodiment of a winding machine according to the invention

In Fig. 1, a first embodiment of the winding machine according to the invention is shown schematically.

The winding machine 1 has a machine frame 3. A spindle carrier 4 in the form of a turret is rotatably mounted in the machine frame 3. The spindle carrier 4 is coupled to a turret drive 15. On the spindle carrier 4, two winding spindles 5 and 6 are rotatably supported and offset by 180 ° to one another. The winding spindle 5 is driven by a spindle drive 14 and the winding spindle 6 by a spindle drive 16. On the winding spindle 5, the bobbins 7.1 are wound on bobbins 8, which are attached and clamped on the winding spindle 5. For this purpose, a thread 11 runs in each winding point via a top thread guide 12 to a traversing device 10. The traversing device 10 is arranged on a frame part of the machine frame 3 which projects parallel to the winding spindles 5 and 6. In the thread running direction behind the traversing device 10, the threads 11 run onto a rotatably mounted pressure roller 9 and are each deposited on the spool surface of the spool 7.1 by means of the pressure roller 9. For this purpose, the pressure roller 9 is partially wrapped around by the threads 11. The pressure roller 9 lies on the spool surface of the spools 7.1 with a certain contact pressure. During the winding, the spindle drive 14 of the winding spindle 5 is regulated in such a way that the peripheral speed of the bobbins 7.1 remains constant.

The second winding spindle 6 is held on the spindle carrier 4 in a lower removal position. Completely wound bobbins 7.2 are held on the bobbin spindle 6 and are ready for removal by a bobbin transport carriage 2.

The exemplary embodiment has a total of 5 winding positions next to one another, so that a total of five completely wound coils 7.2 are held on the winding spindle 6, or five new coils 7.1 are wound simultaneously on the winding spindle 5. The number of winding stations is exemplary. Such winding machines can have eight, ten, twelve or even more winding positions, so that eight, ten, twelve or even more bobbins are held simultaneously on a winding spindle. In the lower area of the machine frame 3, a push-off device 17 is arranged, by means of which the full bobbins 7.2 can be pushed off the bobbin spindle 6. Such a push-off device is known from EP 0 888 243 B1, so that express reference is made here to the content of this document.

The push-off device 17 has an essentially tubular cylinder

20 on. The cylinder 20 extends essentially parallel to the winding spindle 6 in the lower region of the machine frame 3. The cylinder 20 can be acted upon with a pressure medium, for this purpose the cylinder 20 is equipped with a control valve

21 connected, which is coupled via a compressed air line 22 to a compressed air source, not shown here. The control valve 21 is connected via lines to both ends of the cylinder 20, so that a pressure medium can optionally be introduced into the cylinder 20. A carrier 19 is arranged on the circumference of the cylinder 20 and is connected via magnetic forces to a magnetic piston (not shown here) which is guided inside the cylinder 20. On a slide 18 is arranged on the carrier 19 and has a fork-shaped opening (not shown here) at its free end, which engages around the winding spindle 6 at the bearing end. The control valve 21 is controlled via a control unit 23. The control device 23 is connected in a first signal line 25.1 to an operating panel 13. The control panel 13 is arranged on an operating side of the winding machine, from which the bobbin 7.2 is replaced by empty tubes after full winding. For this purpose, the control panel 13 is attached to the free end of the projecting frame part of the machine frame 3.

Via a second signal line 25.2, the control device 23 is connected to a remote-controlled switching means, which in this exemplary embodiment is formed by a switching receiver 24 held on the machine frame 3 and a switching transmitter 26. The switch transmitter 26 is arranged on the coil transport carriage 2.

The bobbin transport carriage 2 has a holding mandrel 32. The holding mandrel 32 is fastened to a frame 27 in a projecting manner. The frame 27 is designed on the underside with a plurality of wheels 28. At the fixed end of the receiving dome 32, a push rod 29 is attached to the frame 27. The push rod 29 is used for the manual movement of the bobbin transport carriage 2. At the fixed end of the holding mandrel 32, a pusher 30 is movably attached to the periphery of the holding mandrel 32. The pusher 30 has a handle 31. The slider 30 can be manually pushed back and forth on the holding mandrel 32 via the handle 31 in order to push off full bobbins held on the holding mandrel 32.

On the push rod 29, the switch transmitter 26 is held at the free end and can be operated by the operator guiding the bobbin transport carriage 2. In order to clear the full bobbins 7.2 held on the winding spindle 6, the bobbin transport carriage 2 is first manually guided into a pick-up position immediately in front of the winding machine 1. In the receiving position, the holding mandrel 32 of the bobbin transport carriage 2 is held in alignment at a short distance from the winding spindle 6 of the winding machine 1. After the bobbin transport carriage 2 has assumed the pick-up position, a switching pulse is triggered by the operator via the switching transmitter 26 and is led to the control unit 23 via the switching receiver 24. Thereupon, the control valve 21 of the push-off device 17 is activated via the control device 23 such that the slide 18 with the carrier 19 is moved from a rest position in the direction of the free end of the winding spindle 6. In this case, the full bobbins 7.2 held on the winding spindle 6 on the winding bobbins 8 are shifted so that the full bobbins 7.2 reach the mandrel 32 of the bobbin transport carriage 2. This situation is shown in Fig. 2. The bobbin transport carriage 2 is held in the pick-up position by the operator. The slide 18 of the push-off device 17 has already reached the free end of the winding spindle 6, so that all the full bobbins 7.2 are pushed onto the holding mandrel 32. The full bobbins 7.2 can now be removed with the bobbin transport carriage 2. The slide 18 of the pusher 17 is returned to its rest position and the now empty winding spindle 2 is equipped with new winding tubes.

In Fig. 3, another embodiment of the winding machine according to the invention is shown schematically. The exemplary embodiment is essentially identical to the previous exemplary embodiments according to FIG. 1, so that reference is made to the preceding description at this point and only the differences are explained below.

In the exemplary embodiment shown in FIG. 3, the remote-controlled switching means for activating the push-off device 17 is in the winding machine

1 formed by a switch button 33. The switch button 33 is at the free end a linkage 34 formed above the winding machine 1. The linkage 34 is designed such that the free end of the linkage 34 arrives in the handling area of an operator who holds a bobbin transport carriage 2 in an accommodating position. The switch button 33 is connected to the control unit 23 via the signal line 25.2.

In order to activate the push-off device 17 for pushing the full bobbins 7.2 off the bobbin tube 6 after the bobbin transport carriage 2 has been positioned, the switch button 33 is actuated by the operator. Via the signal line 25.2, the control unit 23 receives a control pulse for actuating the control valve 21, so that the slide 18 is guided from its rest position to push the full coils 7.2 off.

4 shows a further exemplary embodiment of the winding machine according to the invention, in this case the structure and function of the winding machine and the bobbin transport carriage 2 provided for receiving the full bobbins are identical to the exemplary embodiment according to FIG. 1, so that reference is made to the preceding description and only the differences are shown below.

A stop 40 is formed on the machine frame 3 of the winding machine 1, against which a front abutting edge 42 of the bobbin transport carriage bears in the pick-up position. The stop 40 is preceded by a ramp 43 in the machine frame 3, on which a holding device 38 is formed. The holding device 38 has a catch 39 which interacts with a recess 41 on the underside of the abutting edge 42. Thus, the bobbin transport carriage 2 is fixed in the receiving position. It is not necessary for an operator to hold onto it. A proximity sensor 36 is arranged in the area of the stop 40. The proximity sensor 36 is connected to the control unit 23 via the signal line 25.2. In this embodiment, the operable switching means is not actuated by the operator as previously, but is triggered directly by the bobbin transport carriage 2. As soon as the operator has guided the bobbin transport carriage 2 into the take-up position in front of the winding machine 1, in which the abutting edge 42 lies against the stop 40 of the winding machine 1 in the front region of the bobbin transport carriage 2, the proximity sensor 36 is activated by the front abutting edge 42 of the bobbin transport carriage 2. Thereupon a switching signal is given to the control unit 23 via the signal line 25.2, which leads to the activation of the push-off device 17 and thus to the pushing off of the full coils 7.2.

5 shows a further exemplary embodiment of a winding machine in a sectional view. The detail view represents a cross section of the connection between the winding machine 1 and the bobbin transport carriage 2. The rest of the structure is identical to the previous exemplary embodiment, so that no further explanations are given here.

Compared to the exemplary embodiment shown above, the remote-controllable switching means is implemented by a contact switch 37. The contact switch 37 is integrated directly in the stop surface of the stop 40. As a result, the contact switch 37 can be actuated directly by the abutting edge 42 of the bobbin transport carriage 2. The contact switch 37 is connected via the signal line 25.2 to the control device 23, not shown here.

To fix the coil transport carriage 2 in the receiving position, a holding device 38 is in the form of a. Lock 39 in the machine frame 3 educated. The structure and function are identical to the previous embodiment.

The structure and design of the exemplary embodiments according to FIGS. 1 to 4 are exemplary. Both the winding machine and the bobbin transport carriage can be replaced by similar designs. It is irrelevant here whether the winding machine has only one winding spindle for winding the threads or several winding spindles for winding the threads. The invention thus extends to similar concepts in which an activation of a push-off device for dispensing full coils is triggered by a manually remote-controlled switching means.
