本考案は医療用に使用される留置針、その他合
成樹脂製異径管を連続的に、効率良く製造する装
置に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an apparatus for continuously and efficiently manufacturing indwelling needles and other synthetic resin tubes of different diameters used for medical purposes.
（従来技術及びその問題点）
従来から薬液、体液等を人体に注入し、あるい
は注出するに際し、留置針が使用されていること
はよく知られている。(Prior Art and its Problems) It is well known that indwelling needles have been used for injecting or dispensing medicinal fluids, body fluids, etc. into the human body.
この留置針を製造する方法としては、たとえば
第７図に示すように、合成樹脂管３０の両端部に
支持部材２９，２９を装着し、合成樹脂管３０の
中央部を加熱しながら支持部材２９，２９を互い
に反対方向に移動させ、合成樹脂管３０を引き伸
ばし、その後中央部を切断するような方法がある
（実公昭54−21577号参照）。 As a method of manufacturing this indwelling needle, for example, as shown in FIG. , 29 in opposite directions to stretch the synthetic resin pipe 30, and then cut the central portion (see Utility Model Publication No. 54-21577).
しかしながら、このような方法では、１回の工
程で最大２個の製品しか製造できないという問題
がある。 However, this method has a problem in that only a maximum of two products can be manufactured in one process.
このため、たとえば実開昭57−138624号で提案
されているごとく、上記した方法を連続して行な
う装置も知られている。この装置は、搬送途中で
素材管を加熱するとともに、素材管の両端に固定
した金具の一方は固定杆に支持させ、他方は移動
杆に支持させることにより、移動杆を円筒カムを
利用して移動させ、前記素材管を引き伸ばすよう
にしたものである。 For this reason, there is also known an apparatus that continuously performs the above-mentioned method, as proposed in, for example, Japanese Utility Model Application No. 57-138624. This device heats the material tube during conveyance, supports one of the metal fittings fixed to both ends of the material tube on a fixed rod, and supports the other on a movable rod, and uses a cylindrical cam to control the moving rod. The tube is moved to stretch the material tube.
しかしながら、このような装置では素材管の一

厚、形状等にバラツキが生じやすいという問題が
ある。 However, in such a device, one end of the material tube is fixed and the other end is pulled, so there is a risk that the wall thickness, shape, etc. may become uneven. In addition, in order to manufacture tubes with different shapes and wall thicknesses, it is necessary to replace the rotor that supports the fixed rod and the movable rod, which is troublesome. Since it is constant, there is a problem in that over- or under-heating occurs, and when it is stretched in the next stretching step, variations in thickness, shape, etc. tend to occur.
一方、上記各方法で製造された製品は、支持部

ず、この分生産能率が落ち、コスト高となる。 On the other hand, in the products manufactured by each of the above methods, the attachment ends 31, 31 of the support members 29, 29 are formed into the same diameter cylindrical shape. When the tapered part 33 is attached, there is a problem that it does not come into complete contact with the tapered part 33. For this reason, it is generally necessary to insert a tapered mold into the end portion 31, heat it, and rework it to fit the tapered portion 33 of the connector, which reduces production efficiency and increases costs.
本考案は、以上の問題点を解決するために提案
