Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a lead wire storage device used when manufacturing electric wires / cables (hereinafter referred to as cables).

[Conventional technology and its problems]

When manufacturing a cable, for example, when extruding a jacket on a collective core wire of a communication cable, a lead wire is used for piloting the assembled stranded wire for take-up through an extruder, a cooling tank, or the like. This lead wire is
Depending on the size of the cable to be manufactured, several types are prepared, which are wound on a drum and stored in a corner of the factory.

However, since the number of lead wires is large, the diameter of the drum and the length of the core also become large, which requires a large storage space. Also, when multiple lead wires are wound around a single drum, other lead wires also rotate at the same time when the lead wire is pulled out and wound up, so there is a problem that the rewinding action acts and the winding collapses. It lacked smoothness.

The present invention pays attention to the fact that there is an elongated space on the side surface of various machines in the extrusion molding process and the like, and provides a lead wire accommodation device which can be accommodated in the elongated space and in which lead wires can be easily taken in and out. With the goal.

[Means for Solving the Problems]

In order to achieve the above object, in the present invention, vertical rotation shafts are provided in the middle of both ends of a rectangular frame-shaped frame, and a sprocket is interposed between the upper and lower ends of these rotation shafts. Chains are hung each other, and a plurality of horizontal floor plates are provided on both sides of the cradle along the chains, and support rods are provided between one end of the upper and lower ends of the chain and the other end of the return path. The supporting rod is provided with arms with hooks extending from the rods to the upper surfaces of the floor plates facing each other, and a drive machine for reversing the rotating shaft in the forward and reverse directions is provided on the gantry.

[Action]

In the lead wire storage device according to the present invention configured as described above, when the rotating shaft is rotated in the forward and reverse directions, the chain runs along the floor plate, and the supporting rods located in opposite directions of the floor plate are attached to the floor plates on both sides of the chain. Move in opposite directions along.

Therefore, when one end of the gantry is used as the storage port and the lead wire is connected to the support rod on the outward path via the hook and the chain is run, the lead wire is pulled up and stored on the floor plate as the hook moves. On the other hand, the support rod on the return path reaches the one end side by its action. If a lead wire is connected to this support rod via a hook and the chain is run in the opposite direction, the lead wire is pulled up and stored on the floor plate in the same manner as described above. By repeating the above operation, the required number of lead wires are stored in parallel on each floor plate on both sides of the chain.

〔Example〕

As shown in the figure, vertical rotation shafts 2 and 2'are provided in the middle of both ends of a rectangular frame-shaped frame 1, and sprockets 3 are respectively provided on the upper and lower ends of the rotation shafts 2 and 2 '. It is provided. Chains 4 and 4 are respectively stretched between the upper and lower sprockets 3 at both ends, and support rods 5a and 5b are respectively provided between the upper and lower chains 4 and 4 one end of the outward path (left end in FIG. 1) and the other end of the return path. When the rotating shaft 2 is normally rotated by the drive machine M, the chain 4 travels in the direction of the arrow, and the supporting rods 5a and 5b move to the opposite ends as they run, and the chain line predetermined in FIG. Stop at position. This stop is performed by various means such as detection by a limit switch and control of the rotation speed of the driving machine M. On the other hand, when the rotating shaft 2 is rotated in the reverse direction, the chain 4 runs in the direction opposite to the arrow, and the supporting rods 5a and 5b move to the opposite ends and stop as in the above.

On both sides of the frame 1 along the chain 4, a plurality of horizontal floor boards 6a ..., 6b ... Are provided. The number of steps of the floor plates 6a and 6b is appropriately set according to the vertical space. On the upper surface of each floor plate 6a, 6b, the support rod 5a,
Arms 8a and 8b with hooks 7a and 7b are extended from 5b, and when the lead wire a is connected to the hook 7a of the arm 8a and the rotation shaft 2 is rotated forward and the chain 4 is run,
The lead wire a is pulled up and stored on the floor plate 6a on one side as the hook 7a moves. On the other hand, the returning support rod 5b reaches the opposite side by its action. If the lead wire a is connected to the arm 8b of the support rod 5b through the hook 6b and the rotating shaft 2 is reversed to cause the chain 4 to travel in the opposite direction, the lead wire a is not changed to the other one. It is pulled up and stored on the floor plate 6b at the end. By repeating the above operation, the required number of lead wires a are accommodated in the floor boards 6a and 6b on both sides in a parallel straight line state.

A plurality of hooks 7a, 7b may be provided at required intervals in the length direction of the arms 8a, 8b, and may be movable in the length direction.

Further, it is preferable to provide a guide or a holder for the chain 4 on the gantry 1 to prevent the chain 4 from hanging down and ensure stable traveling. Further, as shown in FIG. 3, each floor plate 6 on the storage port side of the lead wire a is formed.
By providing the rollers 9 facing the edges of a and 6b, the lead wire a can be smoothly guided to the floor boards 6a and 6b.

[Effect of device]

Since the present invention is configured as described above, the entire device can be made elongated, can be placed on the side of the machine which was a conventional dead space, and the lead wire can be stored linearly. Therefore, it can be put in and taken out smoothly.
