管の製造装置に関するものである。[Detailed description of the invention] This invention involves winding a semi-molten strip material in a spiral around the outer periphery of a rotating body while overlapping the side edges, and successively fusing the overlapping side edges. The present invention relates to a synthetic resin pipe manufacturing apparatus that continuously forms tubular bodies.

のである(例えば特開昭52−138571号公報)。 By the way, as shown in FIG. 1, this type of synthetic resin pipe manufacturing apparatus uses a cylindrical cage with one end fixed to the support A on the outer periphery of a support shaft B supported cantilevered on the support A. C is loosely fitted, and a large number of roller-shaped rotors D...D are fitted and held in an inclined posture at a constant angle with respect to the axis of the support shaft by this supporter, and the rotors are held by the magnetic attraction action. By rotating the spindle while adsorbing and rolling it on the outer peripheral surface of the spindle, each rotor can be driven simultaneously. A device is used in which a material F supplied from E onto a rotor D is spirally wound to form a tube G as shown on the left side of the figure (for example, in Japanese Patent Application Laid-Open No. 1986-52- 138571).

か高価につく弊害が生じるのである。 However, in this device, each rotor D...D is driven by the rotation of the support shaft B, and the rotational drive of the rotor is performed in a rolling state by magnetically adhering it to the outer peripheral surface of the support shaft. Therefore, regardless of whether the synthetic resin pipe to be manufactured has a relatively small diameter or is lightweight, if it has a large diameter, a strip of material is wound around the rotor and sent out to the end. A large constriction force is generated during molding and solidification, and the rotor is strongly pressed onto the support shaft, making it impossible to rotate smoothly. U.S. Patent No.
As disclosed in the specification of No. 3532580, if the rotor is supported by a separate bearing device while being spaced apart from the outer periphery of the spindle, the large squeezing force caused by the solidified tube will be applied to the rotor. Since the weight is applied to the bearing portion, each part is required to have strength, resulting in an unnecessarily large overall size, which not only increases weight but also increases costs.

造を容易ならしめるようにしたものである。 The present invention addresses these shortcomings in conventional devices, and uses a cylindrical holding member on the outer circumferential surface of the spindle to attach a large number of rotors at a constant twist angle and connect them in multiple rows. The rotor is forcibly driven at each position by the rotation of the support shaft, and the rotor is rotated in contact with the rotor without receiving the external pressure applied to the rotor in a constricted manner at the bearing part. The rotor is received on the axial surface and mechanically forced to rotate so that the rotation is not inhibited by external pressure from the molded tube, thereby facilitating the manufacture of large synthetic resin tubes.

なされている。 Hereinafter, an embodiment shown in the drawings will be described. In FIGS. 2 to 4, 1 is a support base, 2 is a support shaft supported in a cantilevered manner on the support base, and this support shaft 2 is connected to a pulley 3 at one end. A base shaft 5 which is rotated by appropriate power via a belt 4 wound around the base shaft 5.
It is formed by sequentially and alternately fitting a cylindrical body 2a and a gear 2b whose diameter is slightly larger than that of the cylindrical body at appropriate intervals so that they can rotate integrally, and a threaded portion 5a at the outer end of the base shaft has a threaded portion 5a at the outer end of the base shaft. A fixing nut 5b for integrating the support shaft 2 and base shaft 5 is screwed. Reference numeral 6 denotes a cylindrical holding member which is loosely fitted around the outer periphery of the support shaft 2 with a slight gap by having one end fixed to the support base 1 and the other end supported by a bearing 7 on a nut 5b. The surface has a plurality of slits 6a...6a in the longitudinal direction, and has a constant torsion angle θ with respect to the axis.
A short cylindrical rotor 8 with a concentric pinion 8a provided in each slit is rotatably loaded and held by synthetic resin bearing members 8b at both ends. and the rotor 8
By forming either one of the cylindrical bodies 2a and 2a with magnets, each rotor 8...8 is in a state where part of its circumference protrudes outward from the holding member 6 as shown in FIGS. 3 and 4 due to its attraction action. The pinions 8a are always in rolling contact with the outer surface of the cylinder 2a forming the support shaft 2, and each pinion 8a is meshed with the gear 2b. Reference numeral 9 denotes a material supply device disposed on the side of the end of the support base 1 of the holding member 6, from which a strip-shaped material 10 in a semi-molten state is delivered onto the rotor.

If one of a is used as a magnet, the rotor is attached to spindle 2.
In order to bring them into rolling contact with the outer circumferential surface of the spindle 2, each rotor 8 is connected to the outer circumferential surface of the spindle 2 with the opening edge 6a' of the slit 6a, as shown in FIG. 5, without forming them with magnets. The rotor may be brought into rolling contact with the outer circumferential surface of the support shaft by holding the rotor toward the support shaft.

である。 The device of the present invention having the above-mentioned configuration rotates the support shaft 2 connected to the base shaft 5, so that the cylindrical body 2 on the support shaft is rotated.
Each rotor 8...8 is held in the slit 6a of the holding member 6 in a state in which it is in rolling contact with the outer peripheral surface of the rotor 8.
The pinions 7a on the sides are engaged with the gear 2b, so that they are rotated all at once within the slit, and the slit has a constant torsion angle with respect to the axis of the support shaft 2. As a result, each rotor is tilted at a constant angle θ with respect to the coaxial core, and the material 10 fed onto the rotor from the supply device 9 is wound up in a spiral shape by the rotation of the rotor. In this case, since the material 10a has dimensions that overlap by a certain width, the material is wound up in a spiral and sequentially welded at the side edges,
As a result, from the end of the support shaft 2 on the side opposite to the support base,
It will be taken out continuously as . Since each of the rotors 8...8 is in rolling contact with the outer circumferential surface of the support shaft 2 by the magnetic force or by the opening edge 6a' of the slit 6a in the holding member, the weight of the formed tube P, especially the tube is reduced. The constriction force that accompanies cooling and solidification is absorbed by the rotor's rolling contact with the support shaft 2, making it possible to eliminate excessive loads from being applied to the holding member 6 that serves as a bearing, thereby making it possible to manufacture large-diameter pipes. It makes it possible. If a hard wire is fed out at the same time as the strip-shaped material is wound, and the wire is fed between the overlap portions at the side edges of the material, a waveform with a core material 10' embedded in a spiral shape as shown in FIG. 6 can be obtained. A tube P' is formed.

し得る効果を有するのである。 In this manner, when the synthetic resin pipe manufacturing apparatus according to the present invention is used, a cylindrical tube having one end fixed on the outer circumferential surface of the spindle rotatably supported as a cantilever and loosely fitted around the outer circumference of the spindle. With the holding member, a large number of rotors are arranged in plural rows with a certain twist angle in the longitudinal direction of the spindle, and the rotors are in rolling contact with the outer peripheral surface of the spindle, and the rotors are Since the pinion provided in a part is forcedly driven by meshing with the gear on the support shaft, the weight of the tube P that is spirally wound into a cylindrical shape on the rotor due to the rotation of each rotor. The constriction force that occurs when the hair is cooled and solidified is absorbed by the rolling contact between the rotor and the support shaft, which prevents excessive load from being applied to the rotor bearing, resulting in a lightweight structure. The conventional method is simplified, and each rotor is forcibly driven by meshing a part of the pinion with a gear on the support shaft, so that the rotor is rotated on the support shaft only by the attraction of magnetic force. This has the effect of eliminating structural defects.
