A rope winding device was used which consisted of a spinning roll attached to the rope winding device.

[0003] In this device, first, the rotating arm is rotated around the rotating shaft to bring it close to the mold on which the unvulcanized rubberized canvas is mounted, and then the rope is manually pulled out by a certain length. The rope was then manually wound around the mold once or twice, and then the tip of the rope was fixed to a stop provided at one end of the mold. Thereafter, the tip of the rope away from the mold surface was cut with scissors, and spinning was performed while rotating the mold. At this time, the rotating arm continuously moves in parallel from one end of the mold to the other end. Once the spinning was completed, the rope was cut with scissors, the tip of the rope was fixed to a stop provided at the other end of the mold, and the moving platform with the rotating arm was returned to its original starting position.

0004

[Problems to be Solved by the Invention] However, in the conventional rope winding device, the tip of the pulled-out rope is placed on the mold surface, the rope is wound around the mold, and the tip is locked in the mold stopper. After that, the work of cutting this rope and the work of cutting the rope after spinning were all done by workers. For this reason, the rope winding work is largely dependent on the experience and skill of the worker, resulting in unstable productivity, and there has been a strong desire to automate this work.

[0005] The present invention takes these problems into consideration, and provides a method for automatically installing a rope in a cylindrical body, spinning the rope, and cutting the rope after spinning, without depending on the experience or skill level of the operator. The purpose of the present invention is to provide an automatic rope winding device that can perform the following functions.

[0006]

0010

[Operation] In the automatic rope winding device according to the present invention, the rotary arm is rotated in a direction approaching the cylindrical body to position the touch pulley close to the surface of the cylindrical body, and then the pickup arm is connected to the rotary arm. After turning in the same direction, the push roll located outside the outer peripheral surface of the touch pulley is brought into pressure contact with the cylindrical body surface to grip the end of the rope, and in this state, the clamp of the pickup arm is released and the end of the rope is can be automatically placed on the cylindrical surface. Subsequently, the rope is wound around the cylindrical body approximately once, and after the tip end thereof is locked in the clip portion of the cylindrical body, spinning is started. At this time, the push roll and pickup arm are located away from the cylinder, and only the touch pulley is close to the cylinder.

When spinning is completed, the touch pulley is moved away from the cylindrical body and the pick-up arm is swung close to the cylindrical body, but at this time the rope is gripped by the clamp attached to it, and The rope wrapped around the cylindrical body is cut by the operation of the cutter section. This allows the rope to be cut automatically and this end to be placed in the starting position.

Furthermore, the rope can be easily introduced into the gap between the holding plate of the clamp part and the fixed support, and the rope can be gripped by the holding plate and the fixed support, and at the same time, the blade of the cutter part can be moved. The rope can be cut reliably. In addition, when the end of the rope is bent at the clamp part, even when it is installed in the cylindrical body, it faces toward the outside of the cylindrical body, so that it will not be caught during spinning.

It is designed to rotate outside the outer circumferential surface of No. 2. This is to press down the rope 23 engaged with the touch pulley 22 on the surface of the cylindrical body 2. The toothed portions provided on this surface press against the cylindrical body 2 to prevent the rope 23 from coming off at the beginning of winding. Moreover, when the rope 23 on the surface of the cylindrical body 2 is wrapped around the cylindrical body 2 two to three times while being pressed by the push roll 24 just before the completion of spinning, the rope 23 is prevented from loosening.

On the other hand, the pickup arm 30 is fitted into a rotating shaft 31 provided above the rotating arm 20, and can be rotated by the operation of a cylinder 32. That is, the end of the pickup arm 30 connected to the connecting member 33 at a predetermined angle is connected to a cylinder 32 rotatably attached to the rotating arm 20 at one end.

The pickup arm 30 is the rotating arm 20
Since it is sufficient to rotate the pickup arm 30 independently from the rotation arm 20, there is no need to fit the pickup arm 30 into the rotation shaft 31 provided on the rotation arm 20 as described above.

At the tip of the pickup arm 30, a clamp section 35 for gripping the rope 23 and a cutter section 36 for cutting the rope 23 are arranged in parallel. 4 to 7 show this in detail,
According to this, in the clamp part 35 and the cutter part 36, the cylinder 3 is attached to the wall of the pickup arm 30.
7 and 38 are fixed with bolts or the like so that they stand upright. Each cylinder 37, 38 has a rod 39, 40.

A holding plate 41 made of rubber, synthetic resin, etc. with an uneven surface is installed on the rod 39 of the clamp section, while a thin plate-shaped blade 42 is installed on the rod 40 of the cutter section.
It is clamped and fixed by 3. Of course, the presser plate 41 and the cutter 42 are replaceable.

The clamp section 36 and cutter section 37 are located within a space formed by the pickup arm 30 and an L-shaped fixed support member 46 attached to the wall. A rope 23 is provided between the inner wall 47 of the fixed support member and the presser plate 41, and between the inner wall 47 and the cutter 42, respectively.
It has a gap 48 sufficient for entry. rope 23

The rope 23 is cut while being moved toward the inner wall 47 having a stepped surface.

FIG. 6 shows a state in which the clamp portion 35 is in operation, and the rope 23 is held between the holding plate 41 having the protruding portion 49 and the inner wall 47 having the stepped surface of the fixed support member 46. At this time, the rope 23 is bent. The tip of the rope 23 bent outward can be easily locked to the clip portion at the end of the cylindrical body 2, and spinning can be performed without cutting the rope. If the rope 23 is not bent, the end of the rope will fall in the spinning direction.
There is a possibility of spinning on this.

Next, the operation of the automatic rope winding device according to the present invention will be explained using FIG. 1 and FIGS. 8 to 10.

First, FIG. 1 shows the rope 23 before it is wound around the cylindrical body 2. The rope 23 is held by a clamp part 35 fixed to an upright pickup arm 30, and is engaged with the touch pulley 22 to be attached to the rope winding part. It has reached this point. Further, the rope installation device 4 is connected to the star which is the end of the cylindrical body 2.
It is located at the top position.

Next, as shown in FIG.
After rotating the touch pulley 22 to move it close to the surface of the cylinder 2, the pickup arm 30 is moved to position the end of the rope 23 close to the surface of the cylinder 2. Then, after pressing the rope 23 against the cylindrical body 2 while rotating the push roll 24, the cylinder of the clamp section 35 is operated to release the clamping of the rope 23, and only the pickup arm 30 is rotated to its original position. .

In this state, the cylindrical body 2 is rotated once to wrap the rope 23 around the cylindrical body 2, and then the end of the rope is locked to the clip portion at the end of the cylindrical body 2, and the push roll 2
Return 4 to its original position. At this time, since the tip of the rope 23 is bent by the clamp part 35,
It will not get caught up in the rope 23 during spinning. When this is completed, spinning is performed while rotating the cylindrical body 2 and simultaneously moving the movable table 6 in the axial direction of the cylindrical body.

When spinning is completed, the touch pulley 22 is returned to its original state, and at the same time, the pickup arm 30 is pushed down in a direction approaching the cylindrical body 2, and the clamp portion 35 is activated. That is, the fixed support member 46 and the presser plate 4
When the inclined rope 23 is interposed in the gap 48 provided between the clamp part and the clamp part, the cylinder 37 of the clamp section presses the presser plate 41 against the fixed support member 46, thereby clamping the rope 23 between them. At the same time, the cutter 42 is moved by the operation of the cylinder 38 of the cutter section to cut the rope 23. When the end of the rope is locked to the clip at the end of the cylindrical body 2, the pick-up arm 30 is rotated and stands upright.

In this case, the clamp section 35 and cutter section 36 must be positioned between the touch pulley 22 and the cylindrical body 2. This is the clamp part 35 and the rope 2
This is to make it easier to hold 3 and cut it with the cutter section 36. Therefore, it is necessary to sufficiently adjust the length of the pickup arm 30.

[0032] The movable base 6 is then returned to the initial original position to complete the winding of the rope.
