The linear bodies 1 are wound around a pair of bars 7 standing on a pallet 6 located below the swing base 4 in a bundle of a predetermined shape. Here, the elliptical bundle refers to a state in which the linear body 1 is wound around the pair of bars 7 in an elliptical shape (FIG. 5), and the 8-shaped bundle refers to the pair of bars 7 with the linear body 1 being 8. It refers to the state of being wound into a letter shape (Fig. 6). When the linear body is wound on the bar by a predetermined amount, the operation of the drive source is stopped, the pallet is taken out of the rack, a new pallet is transferred to the rack, and the linear body is continuously wound on the bar for the first time. , At that stage, cut the pallet and the linear body connected to the pallet. Thereafter, the same operation is performed so that the linear body is continuously wound around the bar of the pallet in a bundle of a predetermined shape. Then take out the linear body wound in a bundle from the bar,
It is bundled with tape.

Since the present invention has the above-mentioned structure, its operation will be described below.

When the two drive sources are operated simultaneously after adjusting the link by adjusting the linear body into an elliptical or 8-shaped bundle, the swing base 4 swings along a predetermined locus. Since the supply nozzle 2 is loosely fitted in the opening portion of the base, the nozzle also rotates in unison with the swing base to draw a predetermined trajectory.
The linear body is wound up in a bundle of a predetermined shape on a pair of bars standing on a pallet located below the swing base. As the winding progresses, the linear body is uniformly and evenly wound around the bar by operating the drive source to move the supply plate up and down. When the specified amount of linear material is wound up, the drive source is stopped, and the pallet with the linear material fully wound is removed from the rack by the pallet feeder and a new pallet is transferred to the rack and the same operation is performed. Thus, the linear body is continuously wound up.

Since a large number of supply nozzles are vertically provided in parallel on the supply plate, a linear body is formed by placing a pallet on which a pair of bars corresponding to the number of the supply nozzles are erected on a stand. It is possible to wind up multiple bundles sequentially and simultaneously. Also, of course, when winding a linear body into a bundle of circles, triangles, or quadrangles, adjust the links accordingly to change the direction of rotation of the crankshaft, and make a pallet with one, three, or four bars erected. Need to use.

In the present embodiment, the method of winding the linear body into an elliptic, figure-eight bundle has been described. For example, adjustment of the link mechanism when switching from the figure-eight bundle to the elliptical bundle. To explain, as described above, FIG.

Activating / stopping each drive source, measuring the winding amount of the linear body, operating the pallet feeder,
Although neither cutting of the linear bodies nor adjustment of the link mechanism is shown in the figure, it is managed by a computer, so it is possible to wind the linear bodies into a bundle of a predetermined shape continuously and at high speed. is there.

[0017]

In the winding apparatus for a linear body according to the present invention, the swing base draws a predetermined locus by adjusting the position of the link with respect to the disc and changing the rotation direction of the crankshaft, so that the supply nozzle When the linear body is sent out from the swing base, the linear body is regularly and continuously wound in a pair of bars standing on a pallet located below the swing base, for example, in an elliptic or figure-eight bundle. In addition, if a large number of supply nozzles and pallet bars are installed, a large number of linear bodies can be wound at the same time, so that the productivity of the winding work of the linear bodies is further improved. The linear body is not limited to the leg wire of the electric detonator, of course, and the winding device according to the present invention can be applied to any linear body that is not a very thin or thick wire. Since the mechanism is simple and easy to operate, its application field is very wide and its effect on the industrial world is remarkable.
