Abstract

PURPOSE:To obtain a product having good quality and to make better the feeding of a semi-finished product, by juxtaposing at least one oblique pivotal shaft and plural horizontal pivotal shafts which rotate respectively at even speed in the same direction, and by setting in a line an obliquely moving ring and a fixed ring at each horizontal pivotal shafts. CONSTITUTION:Each pivotal shafts 3, 4 are connected to the preceeding pivotal shafts 3, 4 with a flexible wire 12, so the rotational force is transmitted. When a supporting plate 6 for controlling is appropriately pivoted and fixed by operating a screw 13, the oblique pivotal shaft 3 is in a descending state at required angle and the pitch width of the product is set. Thereafter, while a strip stock for flexible pipe in uncured state is led-in to the oblique pivotal shaft 3 and horizontal pivotal shaft 4 and pivoted, the pivotal shaft 3, 4 wind up this successively and continuously to form a semi-finished product and feed it to the nose direction. At this time, the obliquely moving ring 10 of the horizontal pivotal shaft 4 guides this obliquely towards the feeding direction, and a fixed ring 9 gives to the semi-finished product a rotational force which fills up the shortage of carrying force of the oblique pivotal shaft 3.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a winding material for a flexible tube strip material in a flexible tube manufacturing apparatus.

Conventional technology As a winding material which is a main component of an apparatus for manufacturing a flexible tube by continuously winding up an uncured strip material fed out from an injection port, for example, a winding material having a structure described in Japanese Patent Publication No. 46-25275 is used. There are things.

This known device is constructed by arranging a plurality of rotary shafts in parallel on the circumferential side of a rotary drive shaft installed horizontally on a support base.

Problems to be Solved by the Invention In addition to feeding the semi-finished product, the rotating shafts arranged side by side in an inclined manner require that the diameter of the virtual circle formed by the rotating shafts be gradually reduced toward the tip.

The longer the rotating shaft is, the better the quality of the product can be obtained, but if there is a difference in the diameter of the virtual circle on the proximal end side and the virtual circle on the distal end side, the product may be unsuitable for use as a commercial product. Therefore, the length of the rotating shaft has its own limitations.

Means for Solving the Problems The present invention was devised for the purpose of eliminating the above-mentioned drawbacks of the conventional art.In order to achieve this purpose, a support rod is provided protruding from the support stand, and a support rod is provided on the support rod. Between the support plate and the support stand, at least one inclined rotation shaft and a horizontal rotation shaft are arranged in parallel, which rotate in the same direction at a constant speed, and each horizontal rotation shaft has an appropriate swingable shaft. It is constructed by arranging several tilting rings and fixed rings arranged at appropriate positions between the tilting rings.

Operation: The strip material is continuously wound up into a semi-finished flexible tube by the fixing rings on the tilting rotation axis and the horizontal rotation axis, and the strip material is rolled up by the tilting rings on the tilt rotation axis and the horizontal rotation axis. The products are sent one after another to a cooling tank, which is the final process.

Embodiment The drawings show an embodiment of a winding material for a flexible tube strip material in a flexible tube manufacturing apparatus according to the present invention, and 1 is a machine frame (not shown).
a support stand to be fixed to; 2 a support rod protruding from the support stand; 3;
is the tilt rotation axis, 4 is the horizontal rotation axis.
and the horizontal rotation shaft 4 are arranged on the same circumference with the support rod 2 as the center, each base end is supported by the support base 1 via a bearing (not shown), and the tip end is connected to the horizontal rotation shaft. 4, on the support plate 5 fixed to the support rod 2, and on the adjustment support plate 6, which is adjacent to the support plate 5 on the tilt rotation shaft 3 and rotatably attached to the support rod 2. Each rotation axis 3, 4 is supported respectively.
are rotated at a constant speed in the same direction by drive shafts 7 connected to each other.

9 is a fixing ring fixed in place on the horizontal rotation shaft 2;
Between the fixed rings 90, swingable tilting rings 10 are arranged in a row along the horizontal rotation axis 2.

In the embodiment, a plurality of sets each consisting of an assembly of the tilting rotation shaft 3 and the horizontal rotation shaft 4 are arranged in a stepwise manner along the support rod 2, and the tilting shafts of the next and subsequent stages are The bases of the rotation shaft 3 and the horizontal rotation shaft 4 are supported by the support substrate 11, and each rotation shaft 3° 4 in the next stage is connected to each corresponding rotation shaft 3, 4 in the previous stage by a flexible wire 12 for rotation. power is transmitted.

Further, the adjustment support plate 6 is fixed to the support rod 2 by tightening the base portion with a screw 13, and is used to adjust the inclination angle of the tilt rotation shaft 3.

When the adjusting support plate 6 is rotated and fixed by operating the screw 13, the tilting rotation shaft 3 is tilted at a desired angle to set the pitch width of the product. When the uncured strip material is fed into the inclined rotation shaft 3 and the horizontal rotation shaft 4 and rotated, the rotation shafts 3 and 4 sequentially and continuously wind it up and form a semi-finished product. At this time, the tilting ring 10 of the horizontal rotating shaft 4 tilts in the feeding direction to guide it, and the fixed ring 9 reduces the rotational force by half to compensate for the lack of conveying force of the tilting rotating shaft 3. It is given to the product.

In addition, in the embodiment, the assemblies of the tilting rotation shaft 3 and the horizontal rotation shaft 4 are arranged in stages as a set, but the first stage assembly in the embodiment is simply set to an appropriate length. It may be of.

Further, a plurality of tilting rotation shafts 3 may be used without departing from the essence of the present invention.

Effects of the Invention Since the present invention has the above-mentioned configuration, the winding shaft of the strip material can be lengthened as desired, and therefore, a high-quality product can be obtained, and the tilting ring etc. can be used for semi-finished products. Since it contacts the inner surface in spots, there is no feeding resistance of the semi-finished product, and the cooling effect can be enhanced even when cooling with air.
