Bag. 1257 - 4 -

The wire winding machine according to the invention is used for automatic Winding up of wires, in particular steel wires for the production of steel cord. The rewinder is particularly used for winding up the wires after the upstream drawing machine. The wire winding machine is thereby automates that the full bobbin is automatically removed from the winding position when a predetermined length of wire is reached a movable carrier is moved into an unloading position, the wire between the winding position and the unloading position the bobbin is cut off. There is now the problem that the cut wire end due to its internal stresses deformed so that the last wire layers loosen and / or that the end of the wire protrudes from the coil circumference and / or an undesired space along the length of the coil nimps and / or digs into the inside of the coil. It is therefore advantageous to fix the end of the wire, which is done by gluing or sticking an adhesive strip can be done. It can be paper strips, foil strips and the like.

A particular problem is that the end of the wire must not be cut before it is fixed on the circumference. On the other hand, the wire cut must not take place earlier than the wire on the empty spool, which in the meantime has moved into the winding position, has been applied, - so that a new spool can be formed. Hence the The invention has the object of designing the gluing device so that the gluing process during the movement of the wire spool between the winding position and unloading position can take place. The solution is achieved in that the gluing device is pivotable Has adhesive head and is mounted such that the adhesive head in the path of the spool between the winding position and Unloading position protrudes and due to the movement of the coil in the unloading position in a position tangential to the coil circumference

is pivoted. During this pivoting movement, the delivery of the adhesive strip and the gluing process are triggered. The gluing process therefore does not interrupt the conveyance of the bobbin from the winding position to the unloading position. The wire cut can take place immediately after the gluing process, if - as further proposed - the cutting device in the path of the coil is arranged between the winding position and gluing device.

In a preferred embodiment of the invention, the wire winding machine provided with a standard labeling gun. Such labeling guns are used for labeling, in particular for the pricing of goods. These are hand-held pistol-like devices. They have a labeling head with handle on and a handle referred to in this application as a trigger, which in the labeling head against the Can be pivoted by force of a spring and against the handle. When moving the hand, the handle is pressed together and trigger or triggered by pivoting the trigger relative to the labeling head, the labeling process by the Labeling head is pressed against the goods to be labeled.

Such a labeling gun is according to the invention with their trigger firmly connected to the wire winding machine, in such a way that the coil with its coil circumference on the way between the winding position and the unloading position moves secantially in front of the labeling head and this up to one of the spool circumference Tangential position is pivoted in such a way that the labeling process is triggered by the relative pivoting movement between the trigger and the pivot head is triggered.

Since such a labeling gun is only a limited one Width, the wire winding machine is further designed so that its traversing device at a predetermined Position can be stopped. This ensures that

the end of the wire reaches the area of the labeling device in any case.

An embodiment of the invention is described below. The drawing continuously shows a reel change process with the function of the adhesive head according to the invention. Fig. 6 shows the schematic view of the wire winding machine with the functional elements according to the invention.

In FIGS. 1 and 6, wire 1 is wound onto the almost full flange spool 2. The flange coil 2 is in the quills 3 and 4 rotatably mounted and is driven by motor 5. Through the traversing device 9, the wire is on the spool with the direction of the arrow 10 moved back and forth.

When a predetermined amount of wire has been wound up, the traversing device is 9 is stopped in the middle area of the spool length (dashed line) and the winding process is interrupted. the Quill 3 can now be extended axially. As a result, the Sj_> ule 2 is released from its holder and falls on the Mandrels 6, 7 of the receiving device 8. This state is shown in FIG. The receiving device 8 can now in The direction of arrow 11 can be moved until the circumference of the bobbin comes into contact with the adhesive head 12 in a secant manner. Please refer 3. The adhesive head 12 can be pivoted about a pivot axis 13 which is parallel to the reel axis. With the glue head 12, an adhesive strip 14 is fed in pieces. The adhesive tape 14 can be printed in a suitable manner by printing unit 15 will. The adhesive head 12 is located on the normal plane to the reel on which the traversing device 9 has been stopped (dashed line).

As the carrying device 8 continues to travel, the adhesive head - as shown in FIG. 4 - is pivoted away from the path of the spool and triggered the gluing process. Simultaneously

an empty reel 16 with a further support device 18 is placed in the area of the quills 3 or 4 to prepare a new one Winding process driven with direction of movement 17.

If the carrying device 8 with the full bobbin 2 is now in the direction of the arrow 11 continues, it leaves the pivoting range of the adhesive head 12, which pivots back into its starting position. See FIG. 5. The wire end is now fixed on the circumference of the spool 2 in its central area. It is therefore done now the screw cut. A wire cutter 19 is provided for this purpose Anvil 20 is provided. The wire cutter 19 is - as FIG. 6 shows - pneumatically operated by a cylinder-piston unit 21 and moved back into its starting position by a spring 22. Before the wire cut, the wire was taken from the meanwhile caught in the winding position between the mandrels 3 and 4 driven empty bobbin 16, so that after cutting the wire a new swinging process can begin. The full bobbin 2 is now through ejector 2 3 - a cylinder-piston unit are used - pushed from the mandrels 6, 7 of the support device 8 onto an unloading chute 24 (Fig. 5).

A labeling gun is preferably used as the swiveling adhesive head 12 used. Such a labeling gun is used in particular for the labeling of goods by many companies, e.g. by the Esselte Meto GmbH, Hirschhorn offered. Such labeling guns have a head 26 with a handle 27 rigidly attached to it and a pivotable one relative to the handle Print 28 on. By pressing the handle and trigger together, an adhesive strip 14 is conveyed into an adhesive head 12 and simultaneously labeled by printer 15.
