[Detailed description of the device] [Industrial applications]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire rod feeding device, and more particularly, to a wire rod feeding device that allows anyone to easily replace a cable drum in a short time.

[Prior art]

Generally, a continuously manufactured wire rod is wound around a small cable drum of several kg or a large cable drum having several t, and processed in cable units. As for the wire rod wound around such a cable drum, a stranded wire or the like is manufactured using a plurality of wire rods taken out from a plurality of cable drums. To take out the wire from these cable drums, roll the cable drum or pass the shaft through the through hole provided in the center of the cable drum, lift the cable drum up and float it, and rotate it on the shaft to take out the wire rod. However, there are problems that the device cost is high, space is required, and work efficiency is poor. Therefore, conventionally, a wire rod feeding device as shown in FIG. 5 has been used. That is, the wire rod feeding device 10
Reference numeral 0 has a fitting member 101 that fits into a through hole 202 formed in the bobbin 201 of the cable drum 200. The fitting member 101 has a collar 1 as shown in FIG.
02 is provided, and this collar 102 has a rod 103
Is stuck. A rotating plate 104 formed in a disk shape is rotatably fitted to the rod body 103. The rotary plate 104 is provided in sliding contact with the flange 102, and the rotation speed of the rotary plate 104 is adjusted by the pressure contact force to the flange 102. That is, the tension of the wire rod is adjusted by adjusting the rotation speed of the rotating plate 104.
The tension of the wire is given so as not to impair the quality of the wire and the quality of the product obtained by using the wire. The tension of this wire has an appropriate value depending on the wire and the purpose of use. A rod-shaped arm 105 is fixed to the rotary plate 104. The arm 105 is bent in a dogleg shape, and a roller 106 is rotatably provided at the bent portion. A roller 107 is rotatably provided at the tip of the arm 105. A balancer 108 is provided at a position facing the arm 105 mounting side of the rotary plate 104. The balancer 108 has a structure in which the rotating plate 104 rotates but the rod body 103 rotates.
It is provided so as to rotate with good balance around. Further, on the upper surface of the rotating plate 104, a sliding member 109 is in contact with the rotating plate 104 and rotatably fitted to the rod body 103. An adjusting nut 110 is provided at the tip of the rod 103. Further, a spring 111 is provided between the sliding member 109 and the nut 110 which are fitted to the rod body 103. By turning the nut 110, the strength of the spring 111 is adjusted and the contact resistance between the rotary plate 104 and the collar 102 is changed. An arm 112 is erected on a floor surface (not shown) on which the cable drum 200 is placed. The arm 112 is bent at a substantially right angle, and a roller 113 is rotatably provided at the tip of the arm 112. With such a configuration, first, the fitting member 101 of the wire feeding device 100 is fitted into the through hole 202 of the cable drum 200 as shown in FIG. As a result, the wire rod feeding device 100 has the fitting member 101.
Bobbin 20 of cable drum 200 by collar 102 of
1 is placed on top. In this state, the wire rod 250 pulled out from the cable drum 200 is suspended by the roller 107, then by the roller 106, and then by the roller 113 and taken out. Now, when this wire rod 250 is pulled in the direction shown by arrow A in FIG. 5, as the wire rod 250 wound around the bobbin 201 of the cable drum 200 is unwound, the arm 105 is shown as shown by arrow A in FIG. Rotates around the rod 103. As described above, the conventional wire rod feeding device 100 is guided by the wire rod 250 by pulling the wire rod 250 and rotates along the peripheral edge of the collar 202 of the bobbin 201 of the cable drum 200. The reason why the arm 105 of the wire feeding device 100 is rotated along the peripheral edge of the collar 202 of the bobbin 201 of the cable drum 200 by pulling the wire 250 in this manner is to apply tension to the wire 250. This wire rod 250 is pulled to pull out the wire rod 1
The tension of the wire rod 250 when rotating the arm 105 of No. 00 is performed by changing the contact resistance between the rotary plate 104 and the flange 102 by changing the elastic force of the spring 111 by the nut 110.

[Problems to be solved by the device]

In such a conventional wire rod feeding device, all the wire rods 250 wound on one cable drum 200 are pulled out, and the empty bobbin 201 and the cable drum 200 wound on the wire rod are replaced. The fitting member 101 of the wire feeding device 100 is attached to the through hole 2 of the bobbin 201.
02, the empty bobbin 201 is removed, the cable drum 200 on which the wire is wound is placed at a predetermined position, and thereafter, the fitting member 101 of the wire material feeding device 100 drawn from the through hole 202 of the bobbin 201 is removed. It is fitted into the through hole 202 of the bobbin 201 of the cable drum 200 placed at a predetermined position. For this reason, if the bobbin becomes large, the wire rod feeding device 100 also becomes large in size, the weight increases, and it takes a considerable amount of labor to move the wire rod. In addition, when the number of twisted wires is increased, such as when a plurality of combined wire feeders are combined with a bobbin are used side by side, such as a twisted wire supply when a twisted wire is manufactured by using a plurality of wire rods 250, There is a problem that it takes time to replace the bobbin and the work efficiency is poor. The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a wire-rod-dispatching device capable of easily replacing a cable drum in a short time for anyone.
