A first movable member driving means for driving the first movable member between a proper forward position and a retracted position where the first movable member does not interfere with the guide cylinder and the pail pack; and (d) the first movable member. And a pair of plate-shaped portions opposed to each other at a predetermined interval in a direction parallel to the axis of the guide cylinder and provided in a direction parallel to the axis of the guide cylinder. A second movable member having V-grooves which are wider on the end surface of the first movable member toward the first movable member, and (e) bottom portions of V-grooves of both plate-like portions of the second movable member. Between the bottoms of the V-grooves of both plate-shaped portions of the first movable member Between an advanced position for restraining the serial positioned wire and its second movable member and a retracted position where it does not interfere with the guide tube and pail pack, and a second movable member drive means for driving the second movable member,
(f) A wire provided on one of the first movable member and the second movable member and restrained by the first movable member and the second movable member is provided between the two plate-like portions of the first movable member. And cutting means for cutting between the two plate-shaped portions of the second movable member.

With this configuration, for example, after the holding jig is mounted in the annular space of the pail pack by the holding jig automatic mounting device, the guide cylinder is placed in a state where the pail pack is mounted on the turntable. The wire located in the gap between the lower end of the pile pack and the upper end of the pail pack is cut by the automatic wire cutting device. That is, first, the wire from the guide tube is positioned at a predetermined position where the wire from the guide tube can contact the bottom of the V groove of the first movable member while the guide tube is slowly rotated around the axis of the guide tube by the wire positioning means. Is done. Next, by driving the first movable member and the second movable member in directions approaching each other by the first movable member driving means and the second movable member driving means, V-grooves of both plate-shaped portions of the first movable member are provided. The positioned wire is constrained between the bottom of the first movable member and the bottom of the V-groove of both plate-like portions of the second movable member. Then, in this state, the cutting means provided on one of the first movable member and the second movable member is used between the two plate-like portions of the first movable member and between the two plate-like portions of the second movable member. At which the wire is cut.

As a result, the following effects are obtained by the automatic wire cutting device in addition to the above effects obtained by the presser jig automatic mounting device. That is, conventionally,
The cutting of the wire from the guide tube after storing the wire in the pail pack is performed manually by an operator, and the cutting position of the wire is inevitable to vary around the axis of the pail pack. For example, when the installation space of the winding storage device is narrow, the workability of the wire cutting work by the operator may be deteriorated.
When the wire is cut before the holding jig is attached, an operator mistakenly pulls the wire relatively large from the inside of the pail pack at the time of cutting the wire, and the wire is pailed by the elastic return force due to the twist. There was a risk of jumping out of the pack. On the other hand, according to the automatic wire cutting device, the wire in the gap previously positioned around the axis of the guide cylinder is cut in a state where the wire is restrained between the first movable member and the second movable member. Is performed, the wire can be easily cut regardless of the installation space of the wire winding storage device, and even when the wire is cut before the holding jig is attached, the wire is pailed at the time of cutting. Jumping out of the pack can be suitably prevented.
