Abstract

The already finished cross-wound bobbins contained in the buffer magazines (10 to 17) of the cross-wound bobbin production units (2 to 9) are automatically transferred in successive batches to a circular conveyor (48) by means of bobbin transferrers (61 to 68). The number of cross-wound bobbins belonging to each batch and delivered to the circular conveyor (48) is counted and recorded automatically. This is carried out by means of a programmable data-processing device (59) in conjunction with sensors (77 to 86). The path of the counted and recorded cross-wound bobbins belonging to a specific batch and located in the circular conveyor (48) is followed automatically as far as the reception point (34), and the cross-wound bobbins are then kept ready in an orderly manner at the reception point (34) for further use. <IMAGE>

Method and device for the orderly dispensing of manufactured cross-wound bobbins \

The invention relates to a method and a device for the orderly dispensing of different batches. processing package manufacturing units a Aggregate group continuously-manufactured and in the individual Buffer magazines assigned to cheese-making units collected packages to an acceptance point.

Package manufacturing units can, for example, as Winding machines be designed. That wrap existing coils to form cross-wound bobbins. But you can too as sub-assemblies of spinning machines, in particular open-end spinning machines, be trained.

It is customary to use the cheeses produced by the individual winding devices of a cheese manufacturing unit either by hand or by an automatic package changer to store in a buffer magazine, the is assigned to the cheese manufacturing unit. This Buffer magazine can be designed, for example, as a conveyor belt that normally stands still and only for the purpose of clearing is set in motion.

If there are several package manufacturing units.,. for example, a special acceptance point is provided for the cross-wound bobbins produced, which is located next to a group of units, for example. Difficulties arise when _s · -. On each cheese production units of

Aggregate group different lots are processed. The lots can easily be mixed up at the place of acceptance. especially when there are only slight externally noticeable differences between the parts. It can then easily happen that at the place of acceptance, for example, the cross-wound bobbins produced in containers or Cardboard boxes are packed, mix-ups occur, which are not necessarily noticed immediately. To avoid these difficulties, one can try to be consistent to remove one lot after the other from the corresponding units and transport them to the place of acceptance. Only when the batch is packed does the next batch take its turn and so on. But here it is also inevitable that waiting times occur. As long as one batch has not been accepted and packaged, no other batch can taken from the buffer magazine of another cheese manufacturing unit will. If such a buffer magazine is full, the cheese manufacturing unit must be switched off will.

The invention is based on the object to create the conditions that even if different Batches from the individual package manufacturing units of an aggregate group are continuously produced, an orderly, rapid decrease in the amount collected in the buffer magazines Cross-winding takes place without the risk of mixing up lots.

This object is achieved according to the invention by the characterizing features of claim 1.

According to a further embodiment of the invention, the respective batch is successively distinguishable from one another Transfer partial portions to the circular conveyor. In this case, for example, the number of coils can be one Part portions always be the same. The sensor then only needed to recognize the beginning of the portion and more he would have to recognize again whether a transport position is occupied or not.

It is advantageous to transfer from the package production unit during the transfer of the bobbin to the circular conveyor coming cheeses are locked to the buffer magazine. Filling the buffer magazine and the Clearance of the magazine are separated in time so that one activity cannot disturb the other. In addition, the overview of the content of the Buffer memory will not be lost. ·

According to a further embodiment of the invention, the Transfer of from the package manufacturing unit originating cross-wound bobbins interrupted as soon as a Part of the portion of the batch is in the buffer store and is resumed as soon as the portion of the batch has been transferred to the circular conveyor. If this is done, then it is never there is more than one partial portion in the buffer tank. The handover to the circular conveyor can in this case done by simply clearing the space.

has a total of five hundred hooks, which are in equal parts treatment distances are attached to the chain 50. Addresses 1 to 500 are assigned to the hooks, as shown in FIG. 3 shows. The chain 50 is pulled evenly and the attachment and removal of the bobbins on the hooks and off the hook happens on the fly. The two sensors 85 and 86 are able to recognize address 1, because the hook having the address shown in FIG. 3 has two reflecting disks 162 and 163, while all other hooks only have a reflective washer. Of the Sensor 86 is set to reflecting disk 162 and sensor 85 is set to reflecting disk 163. If both sensors 85 and 86 respond, the hook with address 1 is in front of these sensors. Until The next complete revolution of the circular conveyor 48, the sensor 85 is now inactive, while the sensor 86 continues counts on.

In the data processing device 59 are previously the Distances of the bobbin transfer devices 61 to 68, measured in hook pitches, entered by the sensors 85 and 86 been. In addition, the data processing device 59 the distances between the unloading devices 117 to 125, also measured in hook pitches, input from sensors 85 and 86.

According to FIG. 1, the coil transfer device 61 is in the process of to continuously transfer cheeses from the buffer magazine 10 to the circular conveyor 48. Fig. 1 shows that the Spool transfer device 61 has just transferred the fourteenth cheese of the first batch to the circular conveyor 48.

1212

The sensor 77 has already counted the number of bobbins from the first transferred cheese and the Reported the run of the lot to the data processing device 59. The packages coming from the buffer magazine 10 the first batch should be transferred to the now empty intermediate magazine 35. The package manufacturing unit 3 has already delivered a first partial portion of the second batch to the intermediate magazine 36. The third package manufacturing unit 4 is still in the process of collecting the cross-wound bobbins from the third batch in its buffer store 12. The same is with those produced by the cross-winding unit 5 Cross-wound bobbins of the fourth batch are the case, which are later transferred to the now empty intermediate magazine 38 should be brought. The first portion of the fifth batch is also already in the intermediate magazine Also from the sixth and seventh batch that is currently being produced on the package production units 7 and 8 there are still no cross-wound bobbins in the associated intermediate magazines 40 and 41. The bobbin transfer device 68 of the cheese manufacturing unit 9 is at the moment ·, the last package of the eighth batch to be transferred to the circular conveyor 48.

So while the production of the eighth batch is finished, the handover of the packages for the first batch is taking place already started. All other bobbin transfer devices have been shut down to prevent transfer operation disturb.

1212

Based on this operating state, the orderly transfer is to be explained in greater detail with reference to FIG. 3. The last one, from the package manufacturing unit 9 The cross-wound bobbin 164 coming from the eighth lot is just being transferred to the hook with address 6. The handover action is detected by the sensor 84 and reported to the data processing device 59. The data processing device it is known that sensor 84 removes five hook pitches from sensors 85 and 86 is. The data processing device is also known to have sensors 85 and 86 three hook pitches from the first Intermediate magazine 35 of removal location 34 and thus ten hook pitches away from intermediate magazine 42 are. After the sensor 84 so the presence of the coil 164 on the hook with the address 6 and also the Lot of the bobbin has been determined, the sensor 86 only needs to continue counting in order to activate the data processing device 59 to arrange after a total of fifteen payment steps, an ejector pulse via the operative connection 126 to the control device 129 of the intermediate magazine 42, which is then sent via the operative connection 132 compressed air is applied to the compressed air cylinder 135 at the moment, in which the sensor 156 has the exact position of the hook carrying the cheese. At the same time, the control device acts 129 also the compressed air cylinder 138 via the operative connection 144 with compressed air, so that the slide 150 is brought up to the roller conveyor 153 to catch discarded package and to calm it down before further transport. The further transport in the intermediate magazine 42 can be done in that the flat conveyor starts up briefly and then stops again

1212

or by the fact that the flat conveyor continues to run slowly, because at its end the coils are continuously removed.

While the two coil transfer devices 61 and 68 are active, switches the programmable data processing device. 59 the control device 101 via the operative connection 93 of the bobbin changer 109 and the control device 108 of the Bobbin changer. 116 off. At the same time, the drive devices are via the operative connections 90 and 91, respectively 18 and 25, the buffer stores 10 and 17 are in operation, in order to transfer the collected cross-wound bobbins to the bobbin transfer devices 61 and 68 to feed. The drive devices 19 to 24 of the buffer store 11 to 16, on the other hand, are switched off so that they can continuously pick up cross-wound bobbins. the Control devices 102 to 107 of the bobbin changers 110 to 115 are switched on, so that the bobbin changers continuously finished bobbins from the cross-wound bobbin production units 3 to 8 can be transferred to their buffer memory 11 to 16.

Since the data processing device 59 also counts the number of cross-bobbins delivered to the buffer memory, if the content of each buffer memory is known to it and according to this content it can determine the order the 'coil transfer to the circular conveyor 48 control. the Package transfer depends entirely on the production speed of the package manufacturing units. For clearing, that always comes in an advantageous manner It is the turn of the buffer magazine that has collected the most packages.

9/12/1983

1212

In another mode of operation it is provided that the individual batches in .Teilportionen fixed number of bobbins getting produced. That. The buffer magazines are then cleared in the order of the package production units with the proviso that that cheese-making unit is overturned when clearing, whose buffer magazine does not yet contain the number of packages specified for the partial portion. That concern de package production unit is behind and it can be assumed that this residue will persist. By skipping over the Abräuroens once the cross-wound bobbin unit in question can compensate for the backlog for a certain period of time while the clearing operation then continues without any problems.

In a further operating mode it is provided that a plurality of cheese manufacturing units cross-wound bobbins produce a single batch. At the same time it is provided that two or more adjacent intermediate magazines are assigned to a lot. While one intermediate magazine is being filled, the other can or the other previously filled intermediate magazines can be emptied for further use of the reels. That Filling and emptying of the intermediate magazines takes place very smoothly in this way. In another operating mode is initially the number of cross-wound bobbins delivered to the buffer magazines by the bobbin changer unknown. After the bobbin changer has stopped the unknown number of packages present in the buffer magazine is now successively cleared away and it results a part of the game that varies in size from time to time. The total number of this type

and manner produced coils of a lot is only produced by one in the data processing device 59 addition made. All number results.se and intermediate results are displayed in the game notification device 127 and registered at the same time. Anytime can manual intervention in the operation.

Alternatively, there are also other ways of batch detection instead of observing the bobbins using sensors 77 to 84 possible. As on every package manufacturing unit a certain batch is produced, the number of those delivered to the circular conveyor 48 could be Bobbins, a certain lot also from counting

the work cycles of the associated coil transfer device can be derived. Such a counting method would have to be be checked by the sensor 86 because at idle cycles could occur during the bobbin transfer.

If several intermediate magazines are allocated to a certain batch, the coil can be transferred to the circular conveyor 48 basically from several package production units take place at the same time, provided these cross-wound bobbins of the respective coils Make a batch. The coil transfer device must be in the Be able to tell if a tick is already ticked or not.

The invention is not based on the illustrated and described embodiment and the modes of operation described limited.
