Abstract

PURPOSE:To lengthen the winding axis of a strip stock according to desire and obtain a product having good quality, by juxtaposing one obliquely rotational movement shaft and horizontally rotational movement shaft interlocking according to rotational movement shaft, and setting in a line an obliquely moving ring and a fixed ring at each horizontally rotational movement shaft. CONSTITUTION:The internal strip stock a of flexible pipe in the uncured condition is fed into a rotationally movement shaft 4 and rotationally meved, as a result, the rotationally movement shaft 4 successively and continuously winds this and molds a semi-finished product, then transfers it to the nose direction. When a reinforcing fiber S is fed into the semi-finished product forwarded in the neighborhood of the base of a horizontally rotational movement shaft 8 and an obliquely rotational movement shaft 9, the obliquely rotational movement shaft 9 feeds the semi-finished product in succession to the rotational movement shaft 4. Hence an obliquely moving ring 10 of the horizontally rotational movement shaft 8 guides this obliquely towards the feeding direction, and a fixed ring 11 gives to the semi-finished product a rotational force filling up the shortage of carrying force by only one obliquely rotational movement shaft 9. Additionally external strip stock a' in a uncured state is fed into as covering the reinforcing fiber S. Finally, by making fully integrated structure by heat weld of the semi-finished product and external strip stock a', a strong flexible pie where the wound reinforcing fiber S inhere is successively and continuously wound.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application 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 is something.

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. Between the first support plate provided at the tip of the rod and the support base, a plurality of rotating shafts that mutually rotate at the same speed in the same direction are arranged around the first support rod.
The first support plate has a second support rod protruding from the first support rod, and a second support plate provided at the tip of the second support rod. A tilted rotation shaft and a horizontal rotation shaft which are interlocked with each other and correspond to the rotation axis are arranged between the first support plate and each horizontal rotation shaft (an appropriate number of rotatable It is constructed by arranging a tilting ring and a fixed ring placed at an appropriate position between the tilting rings.

The strip-like material is wound one by one by the rotating shaft to form a semi-finished flexible tube, and the strip-like material is sent to the tilting ring part of the inclined rotating shaft and the horizontal rotating shaft. While urging the feeding of the strip material to the cooling tank, which is the final process, the tilting ring tilts in the feeding direction to guide the strip material in the feeding direction.

Example Example - Example 1 to 4 show a first embodiment of the invention.

1 is a support stand fixed to the machine frame (not shown), 2 is a first support rod protruding from the support stand 1, and 3 is an extension of the first support rod 2 and attached to the tip of the first support rod 2. This is the second support rod installed in series.

Reference numeral 4 denotes a rotation shaft, and the rotation shaft 4 is arranged obliquely on the same circumference centered on the first support rod 2, and its base end is supported on the support base 1 via a bearing (not shown). The tip is supported by a first support plate 5 provided at the tip of the first support rod 2.

The first support plate 5 is rotatably supported at the tip of the first support rod 2, and has a flange 6 on the back side, that is, on the side of the rotation shaft 4, and has a screw 7 screwed onto the flange 6 of B. It is fixed to the first support rod 2 by pressing the tip against the first support rod 2.

Illustration 8, 8, 8. are the five rotating shafts 4, 4° 4.4,
A horizontal rotation shaft corresponds to the four rotation shafts in 4 and is connected to the rotation shafts 4, 4, 4, 4 via the first support plate 5, and 9 is the remaining one of the rotation shafts. It is a tilting rotation shaft connected via the first support plate 5 similarly to the above.

The horizontal rotation shaft 8 has an appropriate number of swingable tilting rings 10, 1.
0. . . . and the tilting rings 10, 10° 10, . It is supported by a second support plate 12.

Reference numeral 13 in the figure denotes an adjustment piece, the adjustment piece 13 has a base 13a rotatably engaged with the second support rod 3, and a screw 14 screwed into the base 1.3a is pressed against the second support rod 3. By doing so, it is rotated to the second support rod 3, and the base 13
The tip of the above-mentioned tilting rotation shaft 9 is attached to the tip of the arm-shaped protrusion from a, and supports it.

When the screws 7 and 14 are operated to properly rotate and fix the first support plate 5 and adjustment piece 13, the rotation shaft 4 and the tilt rotation shaft 9 are tilted at a desired angle, and the pitch of the product is adjusted. After the width is set, the uncured circular strip material a of the flexible tube is fed into the rotating shaft 4 and rotated. When the reinforcing thread S is fed into the semi-finished product that has been formed and sent in the tip direction and sent near the base of the horizontal rotation axis 8 and the inclined rotation axis 9,
The inclined pivot shaft 9 feeds out the semi-finished product following the aforementioned pivot shaft 4. At this time, the tilting ring 10 of the horizontal rotating shaft 8 is tilted in the feeding direction to guide the semi-finished product, and the fixed ring 11 is rotating the tilting shaft 9. Furthermore, an uncured outer strip material a' is fed so as to cover the reinforcing yarn S, and the semi-finished product and the outer strip material a' are completely integrated by heat fusion, thereby reinforcing the reinforcing yarn S. The strong flexible tube contained within the tube is continuously wound one after another.
