Description

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

BACKGROUND TECHNOLOGY For example, Japanese Patent Publication No. 1973-1982 is used as a winding material which is a main component of a device for manufacturing flexible tubes by continuously winding up an uncured strip material sent out from an injection port.
There is a structure described in Publication No. 25275.

This known device is constructed by arranging a plurality of rotary shafts in parallel in an inclined manner around the circumference of a rotary shaft moving shaft installed horizontally on a support base.

Problems to be Solved by the Invention In addition to feeding the semi-finished product, it is necessary for the rotating shafts arranged in parallel in an inclined manner to gradually reduce the diameter of the virtual circle formed by the rotating shafts toward the distal end.

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 conventional drawbacks, and in order to achieve this purpose, a first support rod is provided protruding from the support base, and the first support rod is Between a first support plate provided at the tip of the rod and the support base, a plurality of rotating shafts that mutually rotate at a constant speed in the same direction are tilted on a circumference centered on the first support rod. a second support rod is provided on the first support plate in a protruding manner on an extension line of the first support rod; a second support plate provided at the tip of the second support rod and the first support plate; A horizontal rotation axis of one inclined rotation axis that interlocks with the rotation axis is arranged in parallel between the rotation axis, and each horizontal rotation axis has an appropriate number of swingable tilting rings and a corresponding one. It is constructed by arranging fixed rings arranged at appropriate positions between tilting rings.

Function The strip-shaped material is wound up one after another by the rotating shaft to form a semi-finished flexible tube, and the strip-shaped material is sent to the tilting ring part of the inclined rotating shaft and the horizontal rotating shaft. The tilting ring tilts in the feeding direction and guides the strip material in the feeding direction while urging the feeding of the strip material to the cooling tank, which is the final process of the product.

Embodiment 1 Embodiment 1 FIGS. 1 to 4 show a first embodiment of the present 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 rotation shaft 4 side, and the tip of a screw 7 screwed into the flange 6. It is fixed to the first support rod 2 by being pressed against the first support rod 2.

The illustrations 8, 8, 8 indicate the five rotating shafts 4, 4,
A horizontal rotation shaft corresponding to the four rotation shafts 4, 4, 4 and connected to the rotation shafts 4, 4, 4, 4 through the first support plate 5; 9 is a horizontal rotation shaft of the rotation shaft; The remaining one is also a tilting rotation shaft connected via the first support plate 5.

The horizontal rotation shaft 8 has an appropriate number of swingable tilting rings 10, 10, . . . and the tilting rings 10, 10, 10.
Fixing rings 11, 11, placed at appropriate locations between...
are arranged in a row, and the tip is supported by a second support plate 12 fixed to the tip of the second support rod 3.

13 in the figure is an adjustment piece, and the adjustment piece 13 is a base 13a.
is rotatably engaged with the second support rod 3, and is fixed to the second support rod 3 by press-contacting the screw 14 screwed into the base 13a to the second support rod 3. The tip of the tilting rotation shaft 9 is attached to the tip of the arm-shaped protrusion from the base 13a to support 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. The width is set and then
When the uncured inner strip material a of the flexible tube is fed into the rotating shaft 4 and rotated, the rotating shaft 4 sequentially and continuously winds it up to form a semi-finished product, and also tilts it. Therefore, when the semi-finished product is sent in the selected direction and the reinforcing thread S is fed into the semi-finished product that has been sent near the base of the horizontal rotation shaft 8 and the tilted rotation shaft 9, the tilted rotation shaft 9 Semi-finished products are sent out following the moving shaft 4. At this time, the tilting ring 10 of the horizontal rotation shaft 8 tilts in the feeding direction to guide it, and the fixed ring 11 applies rotational force to the tilt rotation shaft 9 to compensate for the lack of conveyance force of only one of the semi-finished products. Furthermore, reinforcing thread S
The uncured outer strip material a' is sent in to cover the outer strip material a', and the semi-finished product and the outer strip material a' are completely integrated by heat fusion. The flexible tube is wound up one after another.

Second embodiment FIG. 5 shows a second embodiment.

In this second embodiment, a third support rod 3' is connected to the tip of the second support rod 3 of the first embodiment, and a horizontal rotation axis is provided on the circumferential side of the third support rod 3'. 8 etc. (The same members as in the first embodiment are indicated by the same reference numerals in the drawings.

This second embodiment is used depending on the molding pitch or diameter of the product.

Of course, the horizontal rotation shaft 8 and the like may be arranged in multiple stages as in the second embodiment.

In each of the embodiments, the support rods 2, 3, and 3' are integral, but a plurality of support rods may be provided in series.

Reference numeral 15 in the figure shows the drive shaft of the rotating shaft 4, and 16 shows a flexible wire that transfers the rotational force of the rotating shaft 4 to the horizontal rotating shaft 8.
and is transmitted to the tilt rotation shaft 9.

Furthermore, each rotating shaft 4, 4,... is connected to the first support rod 2.
Although they are arranged on the same circumference with the center at the center and have the same diameter, it is sufficient if they have different diameters and have the same circumferential speed.

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