産業上の利用分野
この発明は、空気圧配管可動チューブ及びこれを保持す

のである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a reel unit comprising a movable pneumatic piping tube and a member for holding the tube.
従来の技術
従来のこの種の空気圧配管可動チューブは第３図のよう
に、一端が固定側支持板６に他端が可動側支持板７に支
持されている。2. Description of the Related Art As shown in FIG. 3, a conventional pneumatic piping movable tube of this type has one end supported by a fixed support plate 6 and the other end supported by a movable support plate 7.
すなわち、チューブ６がカール形状をしており、この部
分の伸縮を利用し、前記可動側支持板７をガイド杆８に
沿って移動させることによりチューブ６を可動させてい
た。That is, the tube 6 has a curled shape, and the tube 6 is moved by moving the movable support plate 7 along the guide rod 8 by utilizing the expansion and contraction of this portion.

ーブの可動範囲、すなわちストローク長はカール巻本数
による制限を受けるという問題があった。Problems to be Solved by the Invention However, with such a structure, there is a problem in that when moving over a long stroke, the rate of expansion and contraction is large, and when it contracts, the curled part sag and comes into contact with the movable part of the machine. Another problem is that the movable range of the tube, ie, the stroke length, is limited by the number of curls.

る。Means for Solving the Problems And in order to solve the above problems, the technical means of the present invention is to provide a drum for winding the tube with an air pressure supply port, and a drum for winding the tube, which has an air pressure passage hole, and for the rotation of the drum. It is characterized by having a shaft that serves as an axis, and a spring that biases the drum in the direction of winding the tube onto the drum.

できる。In other words, when moving the tube, instead of using the expansion and contraction of the curled shape of the tube as in the conventional method, the system uses the drum's unwinding and winding, so there is no limit to the stroke length depending on the number of curled tubes. Furthermore, it is possible to prevent the adverse effects caused by sagging during long streaks.
実施例
以下、本発明の一実施例を添付図面にもとづいて説明す
る。Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.
第１図において、１はチューブ巻取りドラムでこの固定
シャフト２とは回転運動を行なえるよう組込まれている
。In FIG. 1, reference numeral 1 denotes a tube winding drum, which is incorporated into a fixed shaft 2 for rotational movement.

ｏに接続されている。前記空気供給口１ｏには、シャフ
ト２に形成された空気圧通路１１が連通して、前記チュ
ーブ４に圧縮空気が送られるようになっている。Further, 3 is a coil spring, one end of which is attached to the tube winding drum 1, and the other end of which is attached to the fixed shaft 2. By this coil spring 3, the drum 1
is biased in the direction to wind up the tube 4. 4 is a tube, which is wound around the tube winding drum 1, and the base end is an air supply port 1 formed in the tube winding drum 1.
connected to o. A pneumatic passage 11 formed in the shaft 2 communicates with the air supply port 1o, so that compressed air is sent to the tube 4.
以上のような構成における作用の説明をする。The operation of the above configuration will be explained.
まず巻取シチューブ４が下方に引張られると巻取シテユ
ープ４に追従してチューブ巻取りドラム１が回転する。First, when the winding tube 4 is pulled downward, the tube winding drum 1 rotates following the winding tube 4.
それにともないチューブ巻取りドラム１に取付けられて
いるコイルバネ３が巻き締められ、コイルバネ３に巻き
方向の力が蓄えられる。Accordingly, the coil spring 3 attached to the tube winding drum 1 is wound tight, and force in the winding direction is stored in the coil spring 3.
チューブ４を巻取るときにはコイルバネ３の蓄えている
反力でチューブ巻取りドラム１が逆回転を行ないチュー
ブ４をチューブ巻取りドラム１に自動的に巻付けること
ができる。When winding up the tube 4, the tube winding drum 1 rotates in reverse by the reaction force stored in the coil spring 3, so that the tube 4 can be automatically wound around the tube winding drum 1.
発明の効果
本発明は、チューブの可動ストロークを従来例に比較し
て格段に増すことができ、従来例のようなチューブのた
るみによる弊害が生ずることを防止できる。Effects of the Invention According to the present invention, the movable stroke of the tube can be significantly increased compared to the conventional example, and it is possible to prevent the disadvantages caused by the slack of the tube as in the conventional example.
