Abstract

PURPOSE:To enable feeding of cable without stopping the rotation of drum even when the projected length of cable 2 is long, by guiding the start-of-winding of cable to be projected through rotation of drum by means of a rotary member fixed on the shaft and a coupling member extending therefrom. CONSTITUTION:Upon feeding of cable 2 through the pull-out port 3 of drum 1, said drum 1 will rotate in the arrow direction A around the shaft 4 inserted through the center of said drum 1. As the drum 1 rotates, the start-of-winding 2a of cable 2 will project gradually in the arrow direction B then guided by a ring (rotary member) 5 provided rotatably on the shaft 4 projecting from the flange 1a of drum 1 and a string (coupling member) extending from said string 5 and pulled toward the center. Consequently, even if the projected length of cable 2 is long, the start-of-winding 2a will never jut considerably from the outercircumference of the flange 1a or buckle resulting in feed-out of cable 2 without stopping the rotation of drum 1.

関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for feeding out electrical cables, optical cables, etc. wound around a drum for laying or supplying to the next process.

〔従来技術〕[Prior art]

ドラムに巻かれたケーブルを繰出すと、ドラムの回転に
よる反力等によって、ドラムの鍔を通して外部に引出さ
れているケーブルの巻始め端が、さらに外部に突き出し
てくるという現象が起る。When a cable wound around a drum is unwound, a reaction force caused by the rotation of the drum causes a phenomenon in which the winding start end of the cable, which is led out through the drum's flange, protrudes further to the outside.

このケーブルの巻始め端の突き出し現象は、特に長尺（
例えば５００ｍ以上）のケーブルにおいて顕著である。This protrusion phenomenon at the beginning of winding of cables is particularly important for long cables (
For example, this is noticeable in cables with a length of 500 m or more.

突き出してくるケーブルの巻始め端をフリーにしておく

当って損傷を受ける。If the winding start end of the protruding cable is left free, if the protruding length becomes long, the winding start end will hit the floor etc. and be damaged.

止を図っていた。しかし、ケーブルの繰出しを途中で停
止することは、ケーブル布設あるいは製造の面で大きな
支障を来たすという問題がある。For this reason, conventionally, a string is tied to the winding start end of the cable, and the string is fixed to the drum flange before the cable is let out. There is a problem with the cable buckling. Conventionally, the protrusion length was monitored from time to time, and when it reached its limit, the cable was stopped from being fed out and the string at the beginning of the fifth turn was re-secured to prevent buckling. However, there is a problem in that stopping the feeding of the cable midway causes a major hindrance in terms of cable installation or manufacturing.

It is in.

This system is characterized in that the winding start end of the cable, which is drawn out through the drum's flange, is connected to the rotating member by a connecting member, and then the cable is fed out.

可能である。1 and 2 show an embodiment of the cable payout method of the present invention. Reference numeral 1 is a drum, and 2 is a cable wound around the drum. The winding start 112a of the cable 2 is the drum 1
It is drawn out to the outside through a drawer opening 3 formed in the collar 1a. A shaft 4 is inserted through the center of the drum 1, and the cable winding start end 2801 of the shaft 4! A ring 5 is loosely fitted into the outside part of the collar 1a of I. ring 5
is rotatable about axis 4. This ring 5 has
The tip of a string 6 tied to the cable winding start end 2a is connected. The length of this string 6 is shorter than the radius of the drum's collar 1a. Both ends of the shaft 4 are supported by a support base 1, and the drum 1 is rotatable around this shaft 4.

剛性の比較的大きいケーブルに適する。When the cable 2 is let out from the drum 1 in this state, the drum 1 rotates in the direction of the arrow. As the rotations overlap, the winding start end 2a of the cable gradually protrudes in the direction of arrow B, but since the winding start end 2a is pulled to the center by the string 6, the protruding cable winding start end 2a has its rigidity. It curves as shown by the dotted line in response to the bending, and will not buckle when it hits the floor. The method of this example is
Suitable for cables with relatively high rigidity.

用いることもできる。In the above embodiment, a ring is used as the rotating member that loosely fits on the shaft, but a hook-shaped member may be used instead. Further, although a string is used as a connecting member for connecting the starting end of the cable winding to the rotating member, a metal wire, a rod, or the like may be used instead.

また回転部材と連結部材は一体ものであってもよい。Further, the rotating member and the connecting member may be integrated.

This embodiment differs from the previous embodiment in that a stable 8 is attached to the outer surface of the drum collar 1a to guide the protruding cable winding start end 2a, and the string 6 passes through this stable 8 to the ring 5. It means that it is connected to. In this embodiment, the force necessary to rotate the ring 5 is used to guide the cable winding start end. That is, when the cable 2 is let out and the drum 1 rotates in the direction of arrow A, the ring 5 is also pulled by the string 6 and rotates in the same direction.

Therefore, when the cable winding start end 2a protrudes, the string 6 winds around the outer circumference of the ring 5 without loosening, so that the protruding winding start end 2a is guided along the stable 8. Become. The method of this embodiment is suitable for cables with relatively low rigidity.

上記実施例では、ケーブル巻始め端のガイド部材として

。As explained above, according to the present invention, the starting end of the cable winding that protrudes as the drum rotates is guided by the rotating member attached to the shaft and the connecting member extending from the rotating member, so even if the protruding length becomes long, This prevents the winding start end from protruding beyond the outer periphery of the collar or from buckling. Therefore, there is an advantage that the cable can be fed out without stopping the rotation of the drum midway.
