DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

The invention relates to a wire-removing machine for bales, especially for pulp bales, consisting of a positioning device for the bales, a cutting device for severing the tying wires tensioned round the bales, in the region of at least one vertical bale side face, a gripper device, by means of which the tying wires, after these have been severed, can be lifted off from the bale, and a winding device which grasps all the lifted-off wires in the lifted-off portion by means of a common fork-shaped longitudinally displaceable winding spindle and winds them to form reels.
A wire-removing machine of the type mentioned is known from German Offenlegungsschrift 3,707,966. With this known apparatus, wires can be removed from bales reliably and automatically.
The object on which the invention is based is, in the known wire-removing machine, to improve the operation of winding the severed tying wires.


SUMMARY OF THE INVENTION

This object is achieved, according to the invention, in that there is a row of guide fingers which are arranged in a comb-like manner and which, after the severed tying wires have been lifted off, are arranged in the region between the winding spindle and the bale, the tying wires running through between the guide fingers during the winding operation.
This measure guarantees that any tying wire to be wound, irrespective of the position which it assumes, is guided reliably and in an oriented manner during the winding operation, so that narrow compact rolls form on the winding spindle. Faults occurring during the winding operation are prevented as a result of the presence of the guide fingers.
Preferably, the guide fingers sit on a common supporting rod, by means of which the guide fingers are maintained in their operating position.
The supporting rod can be arranged with downwardly pointing guide fingers, the lower ends of the guide fingers being located above that position of the gripper device in which lifting strips of the latter come to bear on the bale face for the purpose of grasping the tying wires. When the tying wires are in their lifted-off position and the winding operation is to be initiated, the tying wires are respectively located between two guide fingers, so that the tying wires running onto the winding device are guided reliably. At the same time, the tying wires run through underneath the supporting rod.
Appropriately, the supporting rod is mounted resiliently rotatably together with the guide fingers, so that the row of guide fingers can be displaced out of position in an elastically resilient manner, for example in the event of a collision with the gripper device.
So that the tying wires can be wound up to form compact rolls, there is preferably a press-down device which can be laid against the winding spindle during the winding operation. With a roll increasing in size, the press-down device is lifted off somewhat from the winding spindle.
So that the press-down device can be actuated in a convenient way, it can sit on a pivotably mounted stirrup, by means of which the press-down device can be pivoted into its operating position during the winding operation.
The press-down device can have a continuous strip which is provided, for example, with a rounding on the side facing the winding spindle. During the winding operation, the press-down strip first bears against the surface of the winding spindle and then against the accumulating wire roll.
Alternatively, the press-down device can also be provided with a continuous roller on the side facing the winding spindle.
To guarantee that even the short wire ends run forward reliably in the direction of the winding spindle and cannot lie askew, there are preferably on the press-down device guide pins which are arranged in a comb-like manner and which, during the winding operation, engage into the region between the winding spindle and the gripper device. These guide fingers perform, for the guidance of the short wire ends, approximately the same function as the guide fingers for the long wire ends provid
