Automatic winding machine

The invention relates to an automatic winding machine for large-volume unwinding bobbins, which the winding units of the Winder fed by means of a transport device and guided past the winding stations by one Loading trolleys are handled.

Machines of this type have the purpose of producing large-volume pay-off spools, such as cross-wound bobbins from OE spinning machines, dye bobbins or the like, for their further processing rewind. The delivery of the individual winding units with pay-off bobbins is also to be automated in order to relieve the operating personnel and the downtimes during the loading process shorten.

With the DOS 2 050 OJ59 is a method and an apparatus become known, the application of which allows the loading of automatic winding machines of the type in which a multitude of winding spindles passed a fixed preparation, loading and knotting device will. The procedure described in the listed DOS

309883/0691

- 2 - O8O9

and the device used to carry out the method are, however, not applicable to automatic winding machines in which the winding units are arranged in a stationary manner. Furthermore, with DOS '2 019 570 a device for loading spindles on textile machines has become known, in which empty tubes are withdrawn by means of grippers and large-volume bobbins are removed from a supply arranged above the machine and placed on the spindles. However, this device is especially suitable for feeding spindles on two-for-one twisting machines and continuously supplies one spindle after the other in the manner of known doffer types. Such a device is not suitable for automatic winding machines, since the individual winding units • of such machines work completely independently of one another and their pay-off devices require new pay-off bobbins at different times.

The invention is based on the task of loading drainage devices with large-volume drainage bobbins on automatic winding machines using a * longitudinally movable loading trolley. This object is achieved according to the invention in that the loading trolley has both a conveying device

- 3 - "" 0809

device for transferring the pay-off bobbins to the pay-off devices of the winding units as well as a preparation device known per se in order to be incomplete expired reels for immediate continuation to prepare for the process. It is there according to a further inventive feature of advantage if the conveying device has a receiving member, eg a sliding trough for the immediate transfer of the pay-off bobbins from the transport device having.

The loading trolley is able to drive past a large number of winding units and provides the connecting link between the run-off bobbins passed by the transport device above the winding units and the take-up reels with reel holders provided sequential devices of an automatic winding machine. Every time the sequential device a not yet fully expired reel spool or an empty "sleeve from the unwound position has conveyed to the ejection position, a signal is emitted set, which causes the loading carriage to stop when passing the winding unit in question and to take action. Since the removal and evacuation

animals still wound sleeves because of the large diameter differences to be overcome difficulties prepares and is also uneconomical, it is desirable to have a not fully expired reel so long to leave in the drainage device, to knot again and continue to unwind until it has run empty is.

To feed such a residual bobbin into the winding process again, the preparation device can act on the one located in the unwinding device of the winding station Be formed payoff coil. It is particularly advantageous if the loading trolley with a the winding condition of the one in the ejection position Discharge device located discharge coil is provided determining residual button. Using the remainder, sets the loading trolley thus determines whether it is in the ejection position there is an empty tube or a spool that has not yet been fully unwound. Has the residual button found that the sleeve is still wound, this sleeve is pivoted into the ready position and then sought out the broken thread end and set it at the winding station. The loading trolley can do this with the beginning of the thread in the ready position

be provided with the suction nozzle located in the discharge coil. Furthermore it is
It is advantageous if the loading trolley is provided with a thread lifter that provides the beginning of the thread of the pay-off bobbin for the thread connection process between the pay-off bobbin and the take-up bobbin. After what has been said above, it becomes clear that a pay-off bobbin is always within a winding unit and not within the
mobile loading trolley for the unwinding process
is prepared and that the complex elements of the preparation device are not at every winding station,
but only have to be present once on the loading trolley.

If the residual button has now determined that the signal that caused the loading trolley to stop is on an empty pay-off bobbin can be traced back, the tensioning elements of the bobbin holder become the pay-off device loosened and the empty sleeve removed. This is done in an advantageous manner in that the loading carriage with one the bobbin holder of the drain device for the purpose of removing an empty tube actuating pressure lever is provided.

As already mentioned, the conveying device on the loading trolley can be used to transfer the pay-off bobbins Have a receiving member on the winding units, which is designed as a sliding trough. A particularly advantageous one Handling of the pay-off bobbins is achieved according to the invention in that the sliding trough is horizontal and is arranged vertically displaceable. Since the loading trolley and the transport device are both in can move in the same direction and in opposite directions, it must be ensured that the loading carriage in the If necessary, always finds a new pay-off bobbin. This can be achieved with particular advantage by that the loading trolley with a presence of the transport device to be delivered Take-off coil detecting light barrier is provided. The transport device can be known per se Registration means for the presence of a reel be provided. Instead of a light barrier, mechanical sensing devices can of course also be used be used.

Since the expiry time of large volume coils is correspondingly long, the time for the individual activities of the However, the loading trolley is very short in relation to this a loading trolley can have a larger number

309883/0691

can be assigned by winding units. With automatic Winding machines with fixed winding units are common 50 winding units combined into one machine. The loading trolley is at the long run times therefore quite capable of, several such machines to operate with, for example, a total of 100 to 200 or even more winding units. It is advantageous to when the path of the loading carriage along the winding machines is created so that after a Passing all machines a predetermined starting point is reached.

In the event that the winding unit is swiveling the discharge device is triggered before the loading trolley or an operator has brought a pay-off reel into the ready position, the drainage device can be provided with a locking device that controls the pivoting process blocked for a long time until the loading trolley or the Operator by laying the beginning of the thread ready the lock is released.

An embodiment of the invention is shown in the drawing and is described in more detail below.

In FIG. 1, a side wall 1 of an automatic winding machine can be seen with the fastening tube 2 on which a number of winding units 3 are screwed. A traveling knot 5 is arranged on the support tube 4 such that it can be moved back and forth in a known manner. The side wall 1 has a support frame 6 which carries a transport device 7 which is designed as a circular or chain conveyor and can also be designed for several machines. the

Guides 47 in the transport device 7 are with the raceways 8 of a known blow-off device 9 and the busbars 10 for the still to be described and loading trolleys shown in FIGS. 2, 3 and 4 70 with the support frame 6 to form a unit assembled. The pay-off bobbins 11 are placed on hooks 12 which extend along the guides 47 move the winder. Such an arrangement enables observation and any necessary interventions on the take-up bobbin 14 and on the tube magazine 13 not with special needs. The drain device 16 arranged near the floor corresponds to one already in the patent application P 21 18-443.0 proposed device and shows a pay-off reel 11 'in the suitable drain position and another pay-off reel 11 "in the ready shaft position. The pay-off position is indicated by 17, the standby position is marked with, 22. Before attaching a pay-off reel 11 "through the loading trolley 70, the bobbin holder 20 from the drain position 17 has the one shown in dash-dotted lines Eject position 24 taken. The bobbin holder 20 with an empty tube 25 is in this position brought when a pay-off reel 11 ″ moves out of the ready position 22 during a change process

Is pivoted into the drain position 17. In the ejection position 24, an empty tube 25 can be removed particularly easily, since it slips down when the clamping elements of the bobbin holder 20 are released. Such a bobbin holder can be designed in the manner of the embodiment proposed in patent application P 22 25 555 * 6. In such an embodiment, the clamping elements are released by pressing in the direction of the arrow 26 on the pin 27. The drainage device shown in Figure 1 differs from the already mentioned device proposed only in that the boom is designed with two arms. Each bobbin holder 20 can therefore assume the drain position 17 and two other positions, namely the eject position 24 and the standby position 22, the eject position 24 also being assumed when a not yet completely expired reel II ^{1 is changed} from the drain position 17 to the standby position 22 .

The coil holders 20 are connected in an articulated manner to the arms 19 via the coil arms 49 in the pivot points 21. Thread guide members 23 are also pivotably mounted in the pivot points 21. The thread guide members 2j5 and the

309883/0691

- 11 - ■ 0809

Spool holders 20 can be pivoted relative to one another, while the booms 19 by their pitch, thus 180 ° to be rotated about the shaft 18. This is necessary so that the parts are always the cheapest Position to the surrounding machine parts and take the pay-off bobbin 11 'its optimal position to the thread brake 51 can take. The relative movement of a Coil arm 49 is made by the movement of the rotatable cam lever 28 mounted in boom 19, which via the toothed segment 29 and the intermediate gear, 30 with the coil arm 49 is in operative connection. The pivoting the bobbin arm 49 is controlled by the fixed cams 33 and 35, between which the roller 34 of the cam lever 28 is guided and in this way the law of motion of the cam disks and 35 transfers to the spool arm 49. The thread guide organ 23 takes an angle during the major part of the rotary movement of the boom 19 about the shaft 18 from about 90 ° to the boom 19, namely below Effect of a spiral spring, which cannot be seen here, shortly before the pay-off reel 11 'reaches its position shown assumes, the lever 52 connected to the thread guide member 23 runs against the bolt 53 · As a result the thread guide member 23 is pivoted so that it is the

309 8 83/0691

■ - 12 - 0809

assumes optimal position to the thread brake 51 and at the same time reaches the required distance from the supply reel, so that a cheaper yarn balloon can be formed. * As stated above, the bobbin holder 20 assumes when changing to the standby position 22, first the dash-dotted line ejection position 24 a. Although this position is favorable for removing the empty sleeve 25, it is not, however, for attaching a new reel spool. In order to enable such an attachment, the bobbin holder 20 is therefore pivoted into the ready position 22 and thereby aligned horizontally.

In the eject position 2k , the roller J> k of the cam lever 28 rests against the inner cam disk 55. Next to the cam 33 is the lever 5k, which engages the roller J4. The lever 54 can be rotated via the push rod 55 by pivoting the lever 50 in such a way that it lifts the roller y \. As a result, the bobbin holder 20 is pivoted so that it is aligned horizontally. The pin 27, which is connected to the bobbin holder 20, is now held in place by the pawl 56. When a new pay-off reel 11 ″ is attached and a change process takes place, the pin 27 slides with its angled one

309883/069 1

- 13 - 0809

End of the guide 57 along, the spool arm 49 is pivoted back again until the roller rests on the cam 33.

In the absence of a thread in the thread brake 5I, the traveling knot 5 is caused to move to the relevant winding station and to start the changing process for the pay-off reel 11 *. The cam 58 in the traveling knot starts up and pivots the cam lever 59 counterclockwise. This becomes the push rod pressed down and the angle lever 38 rotated counterclockwise. By means of this pivoting movement the pivot bracket 40, another rod 41 and a ratchet lever 42 are actuated via the rod 39, the latter holding the lock washer 43 for rotation releases until the next rest area.

When pivoting the pivot bracket 40, the pin 60 fixedly connected to this grips the pawl 61 and rotates this counterclockwise. The nose of the pawl 61 thus releases the control lever 62. The control lever 62 can rotate clockwise due to the action of an undetectable torsion spring. Through this Movement, the shift rod 63 is shifted to the right.

309883/0691

Now the end of the switching rod 63 protrudes somewhat from the contour of the side wall 1, as a result of which the loading trolley 70 driving past receives the signal to be active at this winding station. With the pivoting movement of the control lever 62, however, also due to the operative connection of the rod 64, a locking lever.65 is rotated clockwise so far that the nose of the locking lever 65 slides over the contour of the pivoting bracket 4o. This blocks the clockwise movement of the swivel bracket. A renewed request of the traveling knot 5 does not lead to the initiation of the change process, since the locking lever 65 blocks the movement of the pivoting bracket 40 and the movement of the cam lever 59 can be absorbed by the compression spring 66. Finally, the pivoting movement of the control lever 62 via the operative connection of a rod 67 has also brought the angle lever 68 into contact with the valve disk 69, which is acted upon by a suction air flow. If the beginning of the thread 15 of a pay-off bobbin 11 ″ is placed ready in the ready position 22 by the loading trolley 70 or by the supervisor at the valve plate 69 by pivoting the valve plate 69 and passing the beginning of the thread I5 to an air stream, the angle lever 68 is also rotated counterclockwise at the same time.

309883/0691

- 15 - * o8O9

So that the control lever 62 pivots again so far counterclockwise that the pawl 6l the control lever 62 can hold on. By rotating the control lever 62, the locking lever 65 is also in its starting position has been pivoted so that a new change process can now take place on the drain device 16. on this way it is ensured that the traveling knot 5 only initiates a further change process when the beginning of the thread I5 of a waiting bobbin 11 ″ on the valve disk, which is held ready in the ready position 22 69 has been laid out. On the other hand, the signal for the request of the loading carriage 70 is reset again when the thread start 15 provided by the supervisor became.

From Figure 2 it can be seen how the loading carriage 70 can drive past the winding units j5. The loading trolley 70 B has two guide rollers 71 on the support rail 72 which is fastened to the side wall 1. The slide rail 73 is fastened to the busbar 10, along which the loading trolley 70 is guided by two further guide rollers "Jk . The loading trolley 70 consists of various elements which have the following functions

meet: The switch wing 44 is against when starting the protruding end of the shift rod 65 so far, pivoted that the with the switch wing 44 connected switching disk 75 actuates the switch 76. The locking lever 77 can be pivoted clockwise in this way due to the operative connection with the pull magnet 78 be that the tip of the locking lever 77 engages in a notch of the guide rail 73, whereby the loading carriage 70 positioned to the respective winding station 3 will. The remainder of the probe 79 describes an arc of a circle around its fulcrum 80, which is the outer diameter the sleeve 25 is tangent. The pressure magnet 81 swivels the remainder button 79 · Can the armature 82 of the Print magnet 81 perform its full stroke, the tab 85 attached to the same actuates the Switch 84. This is the signal that the sleeve 25 is unwound and must be changed. If, on the other hand, the pressure magnet 81 has not been able to perform its full stroke because the residual button 79 of a thread lap was held on the tube 25, so the switch 84 is not actuated. The pressure lever 85 settles when it is counterclockwise is pivoted onto the pin 27 of the bobbin holder 20. With further swiveling of the pressure lever

309883/0691

- 17 - Ο8θ9

the pin 27 is then displaced axially and the clamping effect of the bobbin holder 20 is canceled. The sleeve 25 can now slip off the bobbin holder 20. The pressure lever 85 is actuated via a rod 86 which is connected to the cam lever 87 in an articulated manner. The cam lever 87 is controlled by the cam disc 89 via the cam roller 88 , which in turn is attached to a shaft 90.

On this shaft 90 all control cams are attached which are necessary to control the reel change. This control group will be referred to as Automatic B in the following. The control of those elements that are necessary for pivoting the bobbin holder into the standby position 22 and for finding and preparing the beginning of the thread 15 is carried out by an automatic A .. This subdivision is necessary so that two different control programs can run, depending on whether one empty tube 25 a new pay-off bobbin 11 is provided or whether in a not completely expired pay-off bobbin brought into the eject position 2Ά only the bobbin holder 20 is pivoted and only the beginning of the thread 15 has to be laid ready again.

309883/0691

The loading trolley 70 is provided with a conveyor which consists essentially of an elevator 91. The elevator 91 has the task of a pay-off reel 11 from hook 12 of the transport device 7 to remove and lower to the level of the horizontally standing bobbin holder 20, in which the Drain bobbin 11 can be pushed.

As can be seen in Figure 3, through two pieces of chain 92 about the idler wheels 93 and 9 ^ · on in each case one run of the chain pieces 92 is attached to the console 95, which in turn supports a per se known telescopic guide 96, as is for example used in office furniture in order to be able to pull out drawers as far as possible. A receiving member is connected to the telescopic guide 96 and consists of a sliding trough 100 which receives a pay-off reel 11. The limit switches 97, 98 and 99 are controlled by the cam 95 ^! operated as soon as it passes it. In Figures 2 and 3, the elevator 9I is shown in the position which, when switched off by the limit switch 98, guarantees a predetermined height for the sliding trough 100 and which allows it to be moved to the left without a

309883/0691

- 19 - 'Ο8θ9

by the transport device 7 passed the payoff coil 11 is triggered. The sliding movement is carried out by the push rod 101 which can be seen in FIG. When the elevator 91 is raised, the eyelet 102 attached to the sliding trough 100 is over the The bent part of the push rod 101 is pushed and a connection is thus established. The push rod is from cam lever 101 'via cam roller I05 controlled by the cam 104 104 is fastened on the shaft 90 and forms part of the automatic mechanism B. One which is known per se Light barrier I05 then gives a signal when a pay-off reel 11 is exactly above the extended sliding trough 100 stands. So that this signal can arise, * the hooks 12 of the transport device 7 are on their ends tiltable reflection plates I06, which the light emitted by the light barrier 105 only then throw it back when a drain spool 11 is attached. When the signal is received, the sliding trough can 100 are run up until the limit switch 97 is switched. Now the reel is 11 taken from the sliding trough 100 and can then by a longitudinal movement of the Push rod 101 can be pulled off hook 12. Of the

309883/0691

- 20 - O8O9

The elevator 91 now moves the sliding trough 100 down until the switch 99 is actuated. the Sliding trough 100 now holds the pay-off reel 11 so that its center point coincides with the longitudinal axis of the reel holder 20 in agreement. When the sliding trough 100 is lowered, the eyelet 102 is over the hook the push rod 107 pushed. By means of the push rod 107 is due to the action of the cam 108, the cam roller 109 and the cam lever, the sliding trough 100 moved to the left and the The pay-off reel 11 is placed on the reel holder 20. The previously proposed bobbin holder 20 is also designed in such a way that a pay-off bobbin can be opened by means of central pressure on the bobbin holder can be pushed open without the clamping having to be released. If a pay-off spool is completely open, the clamping becomes effective again and the sliding trough 100 can be withdrawn by means of the push rod 107 without taking back the pay-off spool.

Before attaching a pay-off bobbin 11, the bobbin holder 20 can be brought into the horizontal position. As previously described, this is done by panning

309883/0691

- 21 - O8O9

of the lever 50 counterclockwise. The spherical end of the push rod 111 engages in the dome of the lever 50 for this purpose Moving the push rod 111 to the left is done by the action of the cam 112 on the Cam roller HJ and the cam lever 114. The cam disk. 112 is attached to the shaft 115 and belongs to the automatic system A. In FIG. 4, the division is shown of all cams on the two automatics A and B can be seen particularly clearly.

The beginning of the thread 15 of a prepared pay-off bobbin 11 is searched for in that the pay-off bobbin 11 "is set in rotation and a suction nozzle 11β is so close to the circumference of the discharge spool 11" pushes until the suction air flow has caught the thread end. In Figure 5 it can be seen that the suction nozzle 116 advantageously with a drive roller 117, the drive motor 118 and the Intermediate gear 119 can be combined to form a preparation device 48. The suction nozzle 116 can be pivoted about its axis 120 down until the drive roller 117 on the circumference of a Run-off coil 11 "is applied.

309883/0691

- 22 - 0809

In Figure 4 it can be seen that with the suction nozzle axis 120 a .Hebel 121 is connected. Via the rod 122, the cam lever 123 and the cam roller 124, the cam 125 can lower and raise the suction nozzle 116. The cam 125 is attached to the shaft 115 and belongs to automatic A.

It can be seen from FIGS. 2 and 4 that the necessary suction air is generated by a fan 1J2 which is driven by the motor 133 via the drive belt 1 ^ \ . Dust and thread residues are caught in the filter box 135. At a suitable point between the suction nozzle opening 116 ¹ and the suction nozzle axis, the suction nozzle U6 is provided with a light barrier known per se, not shown here, which gives a signal when the sucked thread is unwound enough and sucked in. As soon as this state is reached, the drive movement for the pay-off reel can be switched off. The thread start of a pay-off bobbin 11 ″, which is detected by the suction nozzle 116, is pulled by the thread lifter 126 to the valve plate 69. As can be seen in FIG.

309883/0691

O8O9

rod 128, the cam lever 129 and the cam roller lj5O the thread lifter 126 is controlled by the cam I3I. The cam disk Ij51 is with the shaft II5 tied together. The pivot point of the thread lifter 126 in the bearing block I27 is chosen so. that the arc of the circle that the Thread lifter when pivoting describes the surface of the valve disk 69 is tangent and the pin 56 on the same recorded. As a result, the valve plate 69 is pivoted and a suction opening for the thread is released and the angle lever 68 is also pivoted. On its way to the valve plate 69, the thread lifter 126 has the from The thread running from the pay-off bobbin 11 ″ to the suction nozzle opening 116 ′ is detected and as a loop to the valve disk 69 drawn. Since only a certain length of thread is sucked into the suction nozzle II6, the end of the thread is free, when the thread lifter 126 opens the valve disk 69, and can be easily sucked.

In FIG. 4 it can also be seen that an electromagnetic clutch I36 is attached to the shaft of the automatic system A and an electromagnetic clutch 157 is attached to the shaft 90 of the automatic system B. The sprockets I58 and 1J9 are firmly screwed to the two electromagnetic clutches I36 and I37 and are connected to one another via the drive chain J> 2

tied together. The drive chain j52 is driven by the gear motor l40. Automatic A or B can be switched on by means of the two electromagnetic clutches I36, IJJ, depending on the program sequence. The cam 141 on the shaft II5 actuates the switch 142, which switches off the automatic system A at certain times. The cams 145, ¹ ^ - 1 ^ 5, which actuate the switches 146, 147 and 148, are also attached to the shaft 90. The switch 146 switches off the automatic system B at certain times. The switch 147 switches on the elevator 91, and the switch 148 switches on the automatic system A. The gear motor 149 drives the elevator 9I via the chain wheels 3I and the chain 45. The gearbox I50 is used to drive the chassis of the loading trolley

If in ejection position 24 an empty sleeve 25 is on the bobbin holder 20 is, as can be seen from the movement diagram shown in Figure 9, the Sequence of movements on loading trolley 70 is as follows: As soon as the loading carriage 70 has reached the corresponding winding unit has reached the switching wing 44 is pivoted by approaching the switching rod 63 and the Switch 76 actuated. This will make the transmission I50

- 25 - 0809

switched off for the chassis and the gear motor l4o for the drive of the automatic systems A and B as well the motor I33 for the fan 1J52 is switched on. At the same time the pull magnet 78 receives voltage, so that the locking lever 77 can snap into a notch in the guide rail 73. With a slight delay also receives the pressure magnet 8l voltage, so that the remainder button is pivoted. Since the sleeve 25 on the bobbin holder 20 is empty, the pressure magnet 81 can perform its full stroke and actuates the switch 84. As a result the electromagnetic clutch Ij57 of the automatic B switched on and the shaft 90 starts up. Now will the pressure lever 85 is pivoted for releasing the clamping action of the bobbin holder 20, and the empty tube 25 falls onto a conveyor belt 46. At the same time, the push rod 101 has also moved the sliding trough 100 so far that that it is under the transport device 7. Next, the switch 146 switches the Automatic B switched off again. There is now a waiting time for automatic B until the light barrier 105 a signal is given which indicates that a pay-off spool 11 is exactly above the sliding trough 100 is located. With this signal, the elevator 91 is also switched on so that it goes up as high as possible

309883/0691

- 26 - O8O9

that the limit switch 97 can be operated. In addition, the automatic B has started again, so that now the push rod 101 can pull back the sliding trough 100 with the pay-off reel 11 located therein. At the same time, the pressure lever 85 is pivoted back. In the meantime switch 148 has been activated> so that the electromagnetic clutch 156 receives voltage and automatic A starts up. The push rod now presses against the lever 50 so that the bobbin arm pivoted and the bobbin holder 20 is brought into a horizontal position. After the push rod 101 the sliding trough 100 has completely withdrawn, the elevator 91 is switched on and the sliding trough lowered until it actuates the limit switch 98. In the meantime, the automatic system A is switched off by the switch 142 for a predetermined waiting time been. The lowered sliding trough 100 has been coupled to the push rod 107 and is of this moved against the bobbin holder 20. When the pay-off spool 11 is on the spool holder 20, the automatic A- is switched on again by the switch 148. The push rod 111 is withdrawn and at the same time the suction nozzle 116 is lowered. To these movements of the automatic system A is the return

pulling the sliding trough 100 by the automatic system B is superimposed in time. If the push rod 111 has reached its end position, the automatic system A is switched off again for a waiting time by the switch 14-2. This switch-off pulse is used to switch on the drive motor 118 for the drive roller 117 on the suction nozzle 116. The attached pay-off bobbin 11 ″ now rotates and the beginning of the thread 15 is sucked in. In the meantime, the switch 1 ^ 7 has been actuated by the automatic system B, and the elevator 91 runs upwards again until the limit switch 97 is switched B makes the remainder of the full revolution and is then finally switched off by switch 146. When the suction nozzle 116 has sucked in the beginning of the thread far enough, a light barrier emits a signal, as already mentioned The rotary movement for the pay-off bobbin is switched off and the automatic system A starts up again. Next, the suction nozzle 116 is lifted off and the thread lifter. 126 swings past under the suction nozzle opening 116 ', grasps the sucked-in thread and pulls it as a loop to the valve plate 69. At the end During its pivoting stroke, the thread lifter 126 strikes the pin

of the valve disk 69 and opens the same. The thread is now completely pulled out of the suction nozzle 116 and is detected by the suction air flow on the valve plate 69 and sucked in. By pivoting the valve disk 69 the angle lever 68 is pivoted counterclockwise with the control lever 62 and the switch rod 63 withdrawn. The thread lifter 126 then also swivels back, and so does the automatic A is finally switched off. The fan I52 and the gear motor 140 are also switched off. In contrast, the gearbox I50 is switched on, so the loading carriage 70 can resume its passage past the individual winding units.

Located in the eject position. 24 on the bobbin holder " 20 a partially wound sleeve 25, so results The following sequence of movements follows: First of all, the processes are the same as for an empty tube 25 When the pressure magnet 81 receives voltage, it cannot completely pivot the remainder button 79, since the The tip of the residual feeler 79 hits the thread package. The switch 84 is thus not actuated either. This State is evaluated in the electrical circuit so that the electromagnetic clutch lj} 6 the

Automatic A receives voltage and the shaft 115 is engaged. The push rod 111 presses against the Lever 50 so that the spool arm 49 is pivoted and the coil holder 20 is in turn horizontal. The one shown in the movement diagram according to FIG. 5 now falls here first waiting time of automatic A, the push rod 111 is immediately withdrawn and the Suction nozzle 116 lowered. Then the movement processes on automatic A run as described above away. So when the suction nozzle 116 is lowered, is the automatic system A is switched off and the drive for the pay-off reel 11 is switched on. Is the thread wide If enough is sucked in, the signal of the aforementioned light barrier switches the drive of the pay-off reel off and automatic A on again. The suction nozzle then lifts and the thread lifter 126 pulls the thread to the valve disk 69. Now the switching rod 65 is withdrawn and the thread sucked in. If, the thread lifter 126 is swiveled back again, the automatic A, the fan 1J2 and the gear motor 14O switched off and the gearbox I50 for the undercarriage switched on again.

From the movement diagram it can be seen that for searching for a thread start and laying it ready

a swiveled in stand-by reel only two thirds of the time is required is necessary for changing an empty tube for a new, full pay-off spool. This advantage enables it is possible to serve a large number of winding units with a single loading carriage 70.

Of course, under certain operating conditions it can make sense to use the loading trolley in this way to switch that he only executes a program "changing empty tubes against full pay-off bobbins". Located In such a case, if a pay-off reel that has not yet fully expired is in the eject position, it would the loading carriage, when it has scanned this bobbin, continues to move without any additional action. A supervisor could then move the bobbin arm 49 with the pay-off bobbin, which is only partially wound Swivel up and lay the beginning of the thread 15 on the valve plate 69 ready.
