Description

[Detailed description of the invention] This invention is capable of smoothly winding each divided belt that is molded and vulcanized using roto-curing, cut into multiple strips, and sent out by a winding shaft driven by the same drive device. It is an object of the present invention to provide a belt winding device for roto curing, which can be constructed at low cost without providing individual drive devices for each belt on each winding shaft.

An embodiment of this invention shown in the drawings will be described.

A indicates rotary curing, and a is a heating roll that is internally heated.

Two pressing rolls b having a diameter smaller than the heating roll a are arranged so as to be in contact with the heating roll a at an interval equal to a quarter of the circumference of the heating roll a.

The folding roll C is arranged at a position corresponding to the apex of an isosceles triangle whose base is a line connecting the centers of the two pressure rolls b.

An annular steel band d passes from the periphery of the heating roll a, passes between the heating roll a and the pressure roll b, emerges from the outer periphery of the pressure roll b, and is wrapped around the turning roll C.

The unvulcanized wide belt 12 enters between the steel band d and the heating roll a from one pressure roll b, where it is pressed against the heating roll a by the steel band d and is pressure-vulcanized. When the belts 1~ are sent out and go around the outer periphery of the other pressure roll b, they are separated from the surface of the pressure roll b by two small rolls e, and cut vertically into multiple strips by a cutter f between the small rolls e. and divided bells) 12 a , 12 b , 12 C.

The 10th stand 1 that rotatably supports two horizontally parallel rolls 2 and 3 at an interval is Roto Cure A.
is located close to the rear of the

A 20th stand 4 is provided L from the 10th stand 1 and further away from the rotocure A and in front of the bells H2a, 12b, and 12C in the direction of movement.

The 20th roll stand 4 directly supports a fixed bar 6 shown in FIG. 3, and the roll group 5 is rotatably fitted between fixed collars 7 provided near both ends of the fixed bar 6.

The roll group 5 consists of a plurality of rolls 9 and a disk 8, all of which are rotatably mounted on a fixed bar 6.

The disc 8 has divided belts 12 a , 12 b , 1
The belts are arranged at intervals such that they can receive one belt at a time, and are bent so as to separate these belts from each other and regulate their respective passages.

20th - These divided bells next to Le Stand 4, that is, the farthest from Roto Cure A) 12 a, 12
Two winding shafts 10 are provided for winding up the windings B and 12C separately, and the winding shafts 10 are driven simultaneously by the same drive device 11.

By the way, the divided belts 12 a , 12 b , 12 C sent out from Roto Cure A are attached to the winding shaft 10 .
As the bells progress toward the end, they cool and contract in the length, width, and thickness directions, and the thickness differs depending on the part. If the belts are wound simultaneously on the take-up shaft 10, the belts are forcibly fed out from the rotocure A by the steel band d, so that the belts may be wound in a loose state or may be wound tightly, resulting in uniform winding. However, in this proposal, each belt is separated by a roll 9 and a disk 8 installed in the 20th stand 4 in front of the winding shaft, and interference between the belts and belts caused by rubbing against each other is eliminated, and the passage is As a result, belt slack mainly occurs between the 10th stand 1 and the 20th stand 4, and the tension caused by the belt's own weight due to this slack causes the tension between the 20th stand and the winding shaft to increase. The tension is kept approximately constant, and the belt can be wound with uniform strength on each winding shaft that is rotated at the same speed by the same drive device.

The tension due to this self-weight is applied to the first roll stand and the second roll stand.
It can be set within an appropriate range depending on the distance from the zero stand.

Therefore, the roto-cure belt winding device can be constructed easily and inexpensively without requiring a drive device or a guide roller for each winding shaft.

In the embodiment shown in the figure, the winding shaft 10 is two shafts, but the winding shaft 10 is one shaft and the bells l-12a, 12b,
The results were better when 12C was wound at the same time.
