DESCRIPTION:

BRIEF SUMMARY
The present invention relates to a wire coiling arrangement intended preferably for use in a wrapping wire removing arrangement and being of the kind which includes a rotatable wire coiling mandrel incorporating a wire receiving slot which extends at least substantially axially rearwards from a forward end of the mandrel and which has a mouth part or entrance which faces towards the forward end of the mandrel, and further includes a coil ejection arrangement which can be moved relative to the mandrel between a withdrawn, wire coiling position and a forwardly located coil ejection position, for pushing a coil of wire wound on the mandrel axially therefrom.
One object of the present invention is to provide a novel wire coiling arrangement of this kind which is of simplified construction and which is a structural improvement on known wire coiling arrangements.
To this end it is proposed in accordance with the invention that the coil ejecting arrangement is movable along the mandrel and, to facilitate introduction of a wire into the wire receiving slot, that the ejection arrangement carries a wire guide device which in one positional setting of the coil ejection arrangement forms a widened continuation of the mouth part of the slot in a direction away from the forward end of the mandrel. Because the mandrel can be made immovable in the direction of its longitudinal axis, this arrangement is extremely reliable in operation and simple in construction.
Further characteristic features of the invention and advantages afforded thereby will be apparent from the depending claims and from the following description of the invention, which is made with reference to an exemplifying embodiment of the invention relating to the removal of metallic wrapping wires from bales of paper pulp while the bales rest on a conveyor path, and also with reference to accompanying drawings, in which
FIG. 1 is a schematic side view of a plant for removing wrapping wires from bales while the bales rest on a conveyor path,
FIG. 2 is a view of the plant shown in FIG. 1, from above;
FIG. 3 is a perspective view of a wrapping wire removal arrangement used in the plant illustrated in FIGS. 1 and 2 and incorporating a wire coiling arrangement according to the invention;
FIGS. 4-6 are views from above of a wire coiling arrangement similar to that illustrated in FIG. 3, showing the arrangement located in a wire receiving position, a wire coiling position and a coil ejecting position respectively; and
FIG. 7 is an end view of the coiling mandrel seen from the front.
In FIGS. 1 and 2 the reference numeral identifies a first roller path 1 which carries a bale 2 of paper pulp, around which there is wrapped two pairs of mutually parallel steel wires 3, the wires 3 of one pair extending at right angles to the wires 3 of the other pair. The bale 2 is placed on the first roller path 1 in position A, as shown with the bale drawn in full lines in the Figure, and in position B, as shown with the bale drawn in chain lines, this latter bale partially overlapping the bale shown in full lines. The arrangement also includes a turntable 4, on which a bale 2 is placed in position C, and a second roller path 5, which carries a bale 2 placed in position D, in accordance with the full line figure which shows the bale 2, and in position E, in accordance with the figure drawn in chain lines, this latter figure partially overlapping the figure drawn in full lines.
The roller paths 1, 5 are illustrated schematically in the drawings and comprise mutually parallel, driven rollers, the upper surfaces of which rollers lie in one and the same plane and the common transport direction of which is arrowed in FIGS. 1 and 2 of the drawings. The turntable 4 is also illustrated schematically in the drawings and comprises an upper part which is rotatable about a vertical axis and which is provided with driving roller means, not shown in the drawings, by means of which the bale 2 can be moved in two mutually perpendicular directions. The bale 2 is driven in one of said directions when mo
