Method and device for the alignment and individual dispensing of spinning cops

The invention relates to a method for the alignment and individual delivery of spinning heads for further processing, which be presented in a tangled arrangement, and an apparatus for carrying out the method.

When further processing spinning cops, e.g. in a winding machine, it is necessary that the cops are individually and, if necessary, be introduced in a certain position. The spinning cops fall first, e.g. from one Spinning machine, disorganized in copy boxes. Depending on the type of machine for further processing the spinning cops it is necessary to bring this into a certain order, that of the feed device of the downstream Processing machine corresponds.

Systems are already known which are used to remove individual cops from randomly stored spinning cops can. In these known systems, the spinning cops are passed through various alignment stations until they which are suitable for loading the intended machine: -r take a nice position. However, the known solutions are very complex and take up a large amount of space.

These known systems also serve to sort the spinning cops according to certain criteria, so that, for example Towed threads, curtained bobbins, deformed ones

Cops and sleeves as well as telescopically nested cops can be determined.

It is known to use conveyor troughs for sorting cops and other parts. Here are the Workpieces or parts conveyed from a narrow inlet opening to an outlet opening of the same size, whereby at the outlet dosing can take place by excess workpieces falling back or being diverted, i.e. it takes place Although the workpieces or parts are conveyed and metered, there is no such thing as an automatic one Alignment and controlled separation of the parts in a specific sequence. (DE-OS 22 55 091 and 26 30 438)

This is where the invention comes in, which is based on the object to design a method of the type described at the outset and a device so that an alignment and individual delivery of the spinning cops in a simple, space-saving and cop-friendly manner with high operational reliability is achieved.

According to the invention, this object is achieved by " that the cops are brought from a loading entrance onto a first vibrating conveyor track on which they be prepared in the conveying direction and moved in at least one further vibrating conveyor track, with the transition of a cop from one conveyor track to the following conveyor track, the transport the subsequent cops caused by temporarily interrupting the conveying effect of the preceding conveyor track is, in such a way that a transport of successive, separated and aligned in the same direction Single cops to the end of the web is reached.

To carry out the method according to the invention According to the invention, a device used in which vibrating conveyor troughs in straight or angled Web are arranged one after the other, on the entry side of which sensors to detect the presence of a cop are attached. The invention achieves that the presented in a confused heap Spinning cops is first converted into a conveying flow of aligned cops that runs along the length of the web is diluted more and more until a kops sequence is reached in which a single delivery of the cops is possible.

The invention is illustrated in the drawing in an exemplary embodiment and described below. the Figure shows a device for aligning the individual delivery of randomly presented spinning cops, like them is required, for example, for the loading of winding units of a winding machine.

In the figure, a top container 2 is on the entry side of a first conveyor chute on a not shown Bearing arranged in an inclined position, in which the cops 3 are in a confused arrangement. The side wall on the entry side the head container 2 is removed and covered by a panel 4, which releases an adjustable opening, through which the spinning cops 3 arrive in a random manner on a first conveyor trough 1, the width of which is at least equal is the length of the head. The conveyor troughs can have different drives, e.g. by vibrating magnets, rotating unbalance, crank drives or the like. Essential is that the first conveyor trough 1 and the further conveyor troughs can be driven independently and accordingly their conveying capacity, i.e. the volume flow and their sub-

refraction as well as the vibration intensity can be set independently of the other conveyor troughs.

The first conveyor trough 1 has side walls 6, which the presented spinning cops 3 in the direction of a second Guide conveyor trough 7. As soon as the opening 5 is left, those sliding onto the first conveyor trough 1 will be Spinning cops 3 directed and against the second conveyor trough

7 moves. The second conveyor trough 7 takes over the incoming spinning cops 3, with one arranged on the inlet side Sensor 8 for detecting the presence of a cop, e.g. a light barrier is arranged. As soon as the feeler

8 detects the presence of a cop, the first conveyor trough 1 is turned off, so that the promotion of further Kopse in the direction of the second conveyor trough 7 is omitted. The sensor 8 is expedient by half a cop length from a separating gap 9 between the first and second conveyor trough 1, 7 is arranged away.

Because no cops are delivered from the first conveyor trough 1, the flow of cops 3 is diluted, in that only the cops lying on the second conveyor trough 7 continue to a third conveyor trough Io be transported. As can be seen from the figure, the second conveyor trough 7 has an angled path on. Such a design is not required for the function of the device shown in the figure, but is mainly used to adapt the device to the space available in the machine, the spinning cops be given individually. On the inlet side of the third conveyor trough 10, preferably about half a Cop length from the separation gap 11 between the second

and a second sensor 12 for determining the presence of a cop 3 is arranged on the third conveyor trough 7, 10. If the sensor 12 detects the presence of a cop 3, the signal generated by it interrupts the replenishment, further cops by shutting down the second conveyor trough 7. This causes a further dilution of the mass flow of cops. Since the third conveyor trough 10 is still in operation, the before second sensor 12 lying bobbins, which are already partially on the third conveyor trough 10, transported on by themselves, until they arrive at a stop 13 arranged at the end of the third conveyor trough 10.

On the third conveyor trough 10 is between the second sensor 12 and the exit side of the third conveyor trough a third sensor 14 is arranged, which turns off the third conveyor trough 10 at the time in which it determines that the Kops has reached the stop and is therefore in the correct position for further transport.

The cops that have reached the stop 13 are now completely aligned in their waiting position in front of a slide 15, and can now be accessed as required. In the figure, an elevator 16 is shown schematically, the picks up the single cops and brings them to the processing site. Between the third conveyor trough 10 and the Elevator 16 is an inclined floor plate 17 and between the floor plate 17 and the third conveyor trough 10 a Flap 18 arranged. A fourth sensor 19 is arranged at the transition from the floor panel 17 to the elevator 16, which triggers the release of the flap 18 and the actuation of the slide 15 in the absence of a cop, so that another cop is moved over the floor panel 17 to the elevator 16.

The replenishment of the cops 3 is thus controlled as follows: If the first sensor 8 does not detect any spinning cops / is running the first conveyor trough 1 until the sensor 8 detects the presence of a cop and the first conveyor trough 1 turns off. Since the second sensor 12 does not detect anything, the second conveyor trough 7 runs until the second sensor 12 detects the arrival of a cop.

If the fourth sensor 19 detects the absence of a cop, the flap 18 opens and the slide 15 comes into operation, after the end of its movement, which is monitored by a switch 23, the third conveyor chute 10 runs again until the bobbins waiting for the second sensor 12 are displayed on the third sensor 14, until after the cops have reached the waiting position at the stop 13 through the third sensor 14, the third conveyor trough 10 is stopped.

The aforementioned independence of the drives of the conveyor troughs 1, 7, 10 allows these conveyor troughs operate independently of each other. This makes it possible to identify certain operating situations that can arise on the path of movement of the cops, e.g. the formation of Bridges can be countered by increasing the conveying capacity at intervals when cops are being replenished is interrupted.

Some details can be provided on the device described, which increase the operational safety. From the figure it can be seen that the second and third conveyor troughs 7, 10 guide runners attached to the ground 20 may have, which are in the conveying direction

extend and facilitate the alignment of the cops.

Just as the first conveyor trough 1 is delimited by side walls 6, the second and third conveyor troughs 7, 10 are also limited by side walls 21, 22. The side walls 6, 21, 22 are not part of the conveyor troughs, i.e. they are fixed in place and do not vibrate with them. Likewise can the panel 4 be part of the device on which the top containers 2 are ajar after removal of the side wall.

The device described has shown an extremely high level of operational reliability. One achieves that usually only a single cop 3 is on the stop 13 and the third conveyor trough 10 only runs again when the slide 15 after the delivery of one or more cops to the floor panel 17 is back in the starting position is located. The mobility of the floor panel 17, which is inclined, also serves to increase operational reliability is so that a cop located thereon is moved against the elevator 16 with certainty. The height The functional reliability of the device described cannot be easily explained. The orientation of the Cops in the direction of movement occur because of the cop length or greater width of the first conveyor trough 1 Surprisingly quickly and, moreover, the individual spinning cops influence each other during alignment in a favorable manner. The volume flow is reduced by different conveying speeds on and through the conveyor troughs the controlled temporary stopping of the same.

At the cop output controlled by the flap 18, a trailing path scissors 24 can also be arranged, which then cuts off an existing trailing path when the head is at a certain distance from the cutting

place, e.g. in the head elevator 16.
