Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope winding and cutting device, and in the case of molding a power transmission belt, for example, there is a spinning step of winding a rope which is the core wire of the belt around a cylindrical body such as a mold. The present invention relates to a device capable of automatically winding a rope around a cylindrical body and cutting the rope in a step, and fixing the cut rope end to the cylindrical body.

[0002]

2. Description of the Related Art In a spinning process, which is one of the processes for forming a conventional power transmission belt, a rotating arm that rotates in a direction close to a rotatably mounted mold and that moves in the axial direction of the mold is used. , A rope winding device consisting of a spinning roll attached to this was used.

In this apparatus, first, a rotary arm is pivoted about a rotary shaft to bring it close to a mold having unvulcanized rubber cloth attached thereto, and then the rope is manually pulled out by a certain length. Then, this was manually wound around the mold for one to two turns, and then the rope tip portion was fixed to a stopper provided at one end of the mold. Then, the tip of the rope separated 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. When the spinning was completed, the rope was cut with scissors, the tip of the rope was fixed to a stopper provided at the other end of the mold, and then the movable table with the rotating arm was returned to the original starting position.

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, the tip is locked to the mold stopper, and then the work is cut. And, the work of cutting the rope after spinning was all done by workers. Therefore, in many cases, the rope winding operation depends on the experience and skill of the operator, so that the productivity is not stable, and automation of this has been strongly desired.
In response to this request, the applicant of the present invention is Japanese Patent Publication No. 6-9.
An automatic winding device disclosed in Japanese Patent No. 2133 was proposed.

[0005]

However, in this device, after the spinning is completed, the pickup arm having the cutter at the tip thereof is swung to cut the rope located between the touch pulley and the cylindrical body (drum). Therefore, the end of the rope floats from the cylindrical body, and the portion apart from the surface of the cylindrical body hangs in a tail shape, which hinders the winding work of the sheet made of rubber or canvas in the next step. In addition, particularly in the specification with low tackiness of the rope, the rope is unwound when the spun cylindrical body is conveyed, which requires a worker to stop the rope. The present invention has been made in view of the above problems, and an object of the present invention is to provide a rope winding and cutting device that can finish spinning without the need for an operator to stop the rope after spinning is completed.

[0006]

That is, according to the present invention, while the rope installation device is translated along the axial direction of the rotatable cylinder, the rope is spun on the rotating cylinder,
In the rope winding / cutting device for cutting the rope after that, the rope installation device is such that the rope installation device is capable of turning in the direction of the cylindrical body about the axis, and moves together with the turning arm to engage with the rope. The rope winding and cutting device includes a rotatable touch pulley, a brake member that abuts on the touch pulley to clamp the rope, and a heating cutting member that can rotate independently of the rotating arm.

Further, the present invention includes the case where the heating cutting member can move to the surface of the cylindrical body around which the rope is wound, and the case where the guide pulley together with the touch pulley is mounted on the rotating arm.

[0008]

In the rope winding / cutting device according to the present invention, when the spinning is completed, the brake member is actuated to stop the rotation of the touch pulley to clamp the rope between the touch pulley and the brake member, and then the heating cutting member is rotated. Then, the surface of the cylindrical body near the top is brought into contact, and the rope is cut by heating. The rope end cut by heating and melting can be attached to a rubber sheet or canvas wrapped around a cylindrical body. Since the end portion of the rope does not hang down without being separated from the surface of the cylindrical body, the next step of wrapping the sheet made of rubber or canvas can be smoothly performed.
