Bundling device

The invention relates to a device for bundling the wires of wire ties by individual, at different Positioning of the lying wire bundle by means of a piece of binding wire wrapping around the wire package Bundling. . . .

Known devices of this type are generally equipped with binding tongs, the tong arms of which the wire package grip around and pull the binding wire around the wire package and then twist it (German patent specification 1 277 7Jf), These designs can be used to advantage with small collar diameters and low collar heights. PUr great Collar dimensions, e.g. for collar heights of more than 600 mm these constructions are so heavy and extensive that manufacture, operation and maintenance are economical Make use questionable. It is the object of the present invention to limit the area of application mentioned above of automatic bundling devices and to create a device with which also large wire bundles can be bound.

It is then proposed that in a bundling device type mentioned at the beginning a binding wire guide on the upper: side of the wire package, · receiving the beginning of the supplied binding wire, on the inside, the underside and the outside of the wire package along movable guide head, as well as the beginning and the end of the binding

Provide wire piece taking over drill head. This ^{eliminates 1} - the binding tongs with their large space requirements and their heavy swivel and rotary drives. The control, guide and drive elements to be used instead can be implemented relatively easily and are easy to maintain. There is practically no space above the wire bundle, and very little space below and next to the wire bundle for the device itself and the bundling process. -

According to a further step of the present invention, the guide head with two is the beginning of the binding wire between them, rotatable about an axis perpendicularly penetrating the plane of movement of the guide head Provided with clamping plates. This design of the guide head ensures that the binding wire can be pulled around properly from the inner top corner of the wire package along the inside, the bottom and the outside to the outer upper corner, angled or without the binding wire being stronger than given by the shape of the wire package is kinked. The clamping plates adjust themselves automatically according to the direction of pull of the binding wire; that is hot *, the binding wire remains straight at all times, even at the point of exit from the clamping plates. A wire break by bending the binding wire one or more times therefore excluded.

For twisting the ends of the binding wire together the drill head is expedient in the direction of the binding point where the one around the wire package is guided Tie wire crossed over and along the bisector movable to the binding wire ends and on its front side provided with projecting claws, between which the binding wire is taken up. With that are the work steps

Looping around the wire package and twisting the binding wire are clearly assigned to separate puncture parts. Of the The drill head can only be used in you for Tightening and twisting of the binding wire can be formed in the most favorable manner.

It is also recommended to use a separating device for Cutting the piece of binding wire around the wire package to length provide, which cooperates with a clamping device, which the end in question of the cut Piece of binding wire immediately after cutting Holding spring pressure. The piece of binding wire is separated after the guide head has reached the upper end position reached before picking up the binding wire through the drill head. As a result, this will only be for the one in question Bundling required pieces of binding wire separated. The clamping device holds the end of the severed Binding wire until it is gripped by the claws of the drill head. The resilient clamping causes the end of the binding wire to be taken over by the drill head without further ado.

For the unimpeded looping of the wire package, the one above the top of the wire package is useful lying part of the binding wire guide divided lengthways and designed to open downwards. aside from that can this part of the binding wire feed laterally from the cross-sectional plane of the wire bundle in which the bundling takes place, be swiveled out.

The device according to the invention can be advantageous

Fig. 5 in partial section through the guide head and in 6 in partial section through the separating and clamping device for the binding wire.

The wire bundle to be bound lies on a binding table 1, the is interrupted in the area of the bundling device and also leaves the underside of the wire package 2 free here. On a Base plate J5 on the side under the wire bundle is a frame 4 arranged. In addition, a Hubzylin-.der is on the base plate 3 5 pivoted so that its movement in the Level in which the bundling is to take place.

The guided in the lifting cylinder 5 Habkolben 6 carries a PUhrungskopf 7> provided with two rotatable about its central axis, a circular clamping plates 8 is provided and 9 '(Figo 5) / the clamping plate 9 can be hydraulically against the clamping splitter 8 pivot around the binding wire 10 to clamp · A guide rod 11 holds the guide head 7 in the position in which the surfaces of the clamping plates 8 and 9 lie in the plane of movement of the guide head 7. To swivel the lifting cylinder 5, a swivel cylinder 12 is articulated on the frame 4. Furthermore, the frame 4 carries driver rollers / for the binding wire 10, a binding wire guide 14, a cutting and clamping device 15 and a twisting head 16. The front part 17 of the binding wire feed 14 can be unfold it downwards and swivel to the side.

The separating and clamping device 15 is with each other movable cutting knives 18 and simultaneously moving clamping jaws I9 provided, of which the lower is under spring pressure against the upper one (Fig. 6). A hydraulic drive 20 over-

carries its movement via tabs 21 onto the separating knives and clamping jaws and pivots the separating and clamping device 15 via a link 22 in the vertical direction.

The drill head 16 is provided with claws 23 on its end face 5 "'for receiving the binding wire ends. It is driven in rotation by a motor 24 and with another Move hydraulic cylinder 25 in the direction of the binding point.

The binding wire 10 fed by the driver rollers 13 via the binding wire guide 14 is picked up with its front end at the inner upper corner of the wire package 2 by the guide head 7 and clamped between the clerical disks 8 and 9. Then the front part 17 of the binding wire guide 1.4 opens and releases the binding wire 10 (FIG. 2). By actuating the lifting cylinder 5 and the swivel cylinder 12, the guide head 7 is moved downwards, outwards and then upwards again. The clamping plates 8 and 9 each adjust according to the direction of movement of the guide head 7, so that the exit direction of the binding wire 10 always corresponds to the direction of movement (Fig. 3 and 4) of the guide head 7 corresponds so that the binding wire 10 can be placed around the wire package 2 perfectly. Shortly before reaching the upper end position of the guide head J , the driver rollers 13 are stopped. In the last part of its movement, the guide head 7 thus sees the binding wire 10 firmly around the wire package 2 and presses it together. Then the separating and clamping device 15 is actuated, which cuts the length of the binding wire required for bundling and pulls it down into the position shown in broken lines in FIG. Then the
