Description

本発明は、導電路（電線又はケーブル）を巻回するドラムに関する。 The present invention relates to a drum for winding a conductive path (electric wire or cable).

従来、導電路（電線又はケーブル）を搬送するために導電路を巻回するドラムの技術としては、例えば、特許文献１に開示されているような技術が知られている。 Conventionally, for example, a technique disclosed in Patent Document 1 is known as a drum technique for winding a conductive path in order to convey the conductive path (electric wire or cable).

特許文献１の図３に図示するように、ドラム（特許文献１においては「ケーブルドラム」という）の鍔部には、抜き孔（「巻始口」とも呼ばれる）が形成されている。 As shown in FIG. 3 of Patent Document 1, a punched hole (also referred to as “winding opening”) is formed in a flange portion of the drum (referred to as “cable drum” in Patent Document 1).

特開２００１−３５４３６２号公報JP 2001-354362 A

従来技術では、例えば、図５及び図６に図示するドラム１００ように、鍔部１０１の巻始口１０２に丸棒状の飛び出し防止部１０３が複数（図５及び図６においては２本）設けられているものと、図７に図示するドラム２００のように、鍔部２０１の巻始口２０２に図５及び図６に図示するような飛び出し防止部が設けられていないものとがあった。 In the prior art, for example, a plurality of round bar-shaped pop-out preventing portions 103 (two in FIG. 5 and FIG. 6) are provided at the winding start port 102 of the flange portion 101 as in the drum 100 illustrated in FIGS. In some cases, like the drum 200 shown in FIG. 7, the winding start port 202 of the flange 201 is not provided with a pop-out preventing part as shown in FIGS.

図５及び図６に図示するドラム１００は、細物の導電路（例えば、細物電線、ケーブル）を巻回するために用いられている。図５に図示するように、飛び出し防止部１０３は、細物の導電路をドラム１００に巻回した状態において、上記導電路が巻始口１０２から飛び出すのを防止するため、巻始口１０２における鍔部１０１の周方向に沿った一対の縁部１０４、１０５を繋ぐように設けられている。飛び出し防止部１０３は、この軸方向の一端が一方の縁部１０４に溶接されるとともに、軸方向の他端が縁部１０５に溶接されることにより、鍔部１０１と一体となるように設けられている。 The drum 100 shown in FIGS. 5 and 6 is used for winding a thin conductive path (for example, a thin wire, cable). As shown in FIG. 5, the pop-out prevention unit 103 prevents the conductive path from jumping out from the winding start opening 102 when the thin conductive path is wound around the drum 100. It is provided so that a pair of edge parts 104 and 105 along the circumferential direction of the collar part 101 may be connected. The pop-out preventing portion 103 is provided so as to be integrated with the flange portion 101 by welding one end in the axial direction to one edge portion 104 and welding the other end in the axial direction to the edge portion 105. ing.

図７に図示するドラム２００は、太物の導電路（例えば、太物のケーブル）を巻回するために用いられている。ドラム２００は、太物の導電路を巻回した状態において、上記導電路が巻始口２０２から飛び出す虞がないため、図５及び図６に図示するような飛び出し防止部が設けられていない。 The drum 200 illustrated in FIG. 7 is used for winding a thick conductive path (for example, a thick cable). The drum 200 is not provided with a pop-out preventing portion as shown in FIGS. 5 and 6 because there is no possibility that the conductive path will jump out of the winding start port 202 in a state where a thick conductive path is wound.

ところで、従来技術では、飛び出し防止部が設けられていないドラム２００を用いた場合、つぎのような問題点があった。すなわち、ドラム２００に、例えば、細物の導電路を巻回した後、必要な分を引き出しては切断し、また、巻き戻す作業を繰り返すことや、その後、ドラム２００を転がして搬送することで、緩んだ上記導電路が巻始口から出てくる現象が生じる。このように巻始口から出てきた導電路を無理に引き出すと導電路が損傷し不具合が生じる虞があるという問題点があった。 By the way, in the prior art, when the drum 200 not provided with the pop-out prevention unit is used, there are the following problems. That is, for example, after winding a thin conductive path around the drum 200, a necessary portion is pulled out and cut, and the rewinding operation is repeated. Thereafter, the drum 200 is rolled and conveyed. A phenomenon occurs in which the loose conductive path comes out of the winding start. As described above, forcibly pulling out the conductive path coming out from the winding start port causes a problem that the conductive path is damaged and a malfunction may occur.

上記問題点に対応するために、飛び出し防止部１０３が設けられたドラム１００を用いることが考えられる。しかしながら、ドラム１００では、太物の導電路に用いる場合や、電気試験のため巻始口１０２から導電路を出しておきたい場合、飛び出し防止部１０３が邪魔であるため使用することができないとう問題点があった。 In order to cope with the above problem, it is conceivable to use the drum 100 provided with the pop-out prevention unit 103. However, when the drum 100 is used for a thick conductive path or when it is desired to leave a conductive path from the winding start port 102 for an electrical test, the pop-out prevention unit 103 is in the way and cannot be used. There was a point.

さらに、上記２つの問題点に対応するために、従来では、２種類の構造のドラム１００、２００を所有する必要があったことから、ドラムの製造コストや管理コストが嵩んでしまうという問題点があった。 Furthermore, in order to cope with the above two problems, it has been necessary to own the drums 100 and 200 having two types of structures in the past, which increases the manufacturing cost and management cost of the drums. there were.

つぎに、ドラム１に細物の導電路を巻回したときの作用について説明する。
ドラム１に、細物の導電路（例えば、細物電線、ケーブル）を巻回する場合は、あらかじめ、飛び出し防止部材２１を巻始口１３に取り付けた状態にする。上記取り付けた状態にしておくことにより、飛び出し防止部材２１（軸部２４）に、上記導電路が当接し、巻始口１３からの導電路の飛び出しが防止される。 Next, the operation when a thin conductive path is wound around the drum 1 will be described.
When winding a thin conductive path (for example, a thin wire, cable) around the drum 1, the pop-out preventing member 21 is attached to the winding start port 13 in advance. By being in the attached state, the conductive path comes into contact with the pop-out preventing member 21 (shaft portion 24), and the conductive path is prevented from jumping out from the winding start port 13.

また、飛び出し防止部材２１における軸部２４の外周面が平面状に形成されているため、飛び出し防止部材２１（軸部２４）に、上記導電路が当接しても導電路が損傷する虞がない。 Further, since the outer peripheral surface of the shaft portion 24 in the pop-out preventing member 21 is formed in a flat shape, there is no possibility that the conductive path is damaged even if the conductive path contacts the pop-out preventing member 21 (shaft portion 24). .

つぎに、ドラム１に太物の導電路を巻回したときの作用について説明する。
ドラム１に、太物の導電路（例えば、太物のケーブル）を巻回する場合は、あらかじめ、飛び出し防止部材２１を巻始口１３から取り外した状態にする。上記取り外した状態にしておくことにより、図７に図示する従来の飛び出し防止部が設けられていないドラム２００と同様に使用することができる。 Next, the operation when a thick conductive path is wound around the drum 1 will be described.
When winding a thick conductive path (for example, a thick cable) around the drum 1, the pop-out prevention member 21 is removed from the winding start port 13 in advance. By leaving it in the removed state, it can be used in the same manner as the drum 200 that is not provided with the conventional pop-out prevention unit shown in FIG.

つぎに、ドラム１に導電路を巻回した後、電気試験を行うときの作用について説明する。
電気試験を行う場合は、まず、飛び出し防止部材２１を巻始口１３から取り外した状態でドラム１に導電路を巻回する。電気試験後、導電路の端末部を切断した後に飛び出し防止部材２１を巻始口１３に取り付けた状態にする。上記取り付けた状態にすることにより、上記導電路が細物電線、ケーブルだった場合であっても、飛び出し防止部材２１（軸部２４）に、導電路が当接し、巻始口１３からの導電路の飛び出しを防止することができる。このように、電気試験後、導電路の端末部を切断した後に飛び出し防止部材２１を上記取り付けた状態にすることにより、従来では対応できなかった、電気試験のため巻始口から導電路を出しておきたいような場合にも対応することができる。 Next, after the conductive path is wound around the drum 1, the operation when an electrical test is performed will be described.
When conducting an electrical test, first, a conductive path is wound around the drum 1 with the pop-out preventing member 21 removed from the winding start port 13. After the electrical test, the jumping prevention member 21 is attached to the winding start port 13 after cutting the end portion of the conductive path. Even if the conductive path is a thin wire or cable, the conductive path comes into contact with the pop-out prevention member 21 (shaft portion 24) and the conductive path from the winding start port 13 is maintained. Jumping out of the road can be prevented. In this way, after the electrical test, by cutting the terminal portion of the conductive path, the pop-out prevention member 21 is put in the above-described state, so that the conductive path is taken out from the start of the winding for the electrical test, which could not be handled conventionally. It is possible to cope with cases that you want to keep.
