[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for automatically inserting a belt sleeve. More specifically, the present invention relates to a vulcanized or unvulcanized cylindrical belt sleeve which is opened to a shaft of a processing apparatus such as a cutter apparatus. The present invention relates to a belt sleeve automatic insertion device and a belt sleeve automatic insertion device capable of automatically and accurately inserting and installing the belt sleeve in a state where the center of the opening of the belt sleeve coincides with the center of the shaft.

[0002]

2. Description of the Related Art In a conventional method for manufacturing a low-edge V-belt, a cloth with rubber is wound around a mold by 1 to 3 plies, and then an unvulcanized rubber sheet in which short fibers are mixed in the width direction is wound. A cord made of fiber or aramid fiber was used as a core wire, and then spun in a spiral form. Further, the same unvulcanized rubber sheet as described above was wound around to complete the molding, and a jacket was inserted into the sheet and vulcanized. The operator inserts the belt sleeve removed from the mold into the shaft of a cutter device covered with a rubber sleeve made of a rubber sheet, expands the rubber sleeve and fixes the belt sleeve on the shaft, and the trapezoidal cross section is formed by the cutter. Was cut into a ring-shaped V-belt. In such work, a device for automatically inserting and installing the belt sleeve into the shaft of the processing device has been desired.

On the other hand, conventionally, there has been proposed a device for attaching a V-belt to a pulley of a measuring device in order to measure a ring-shaped V-belt obtained by cutting a belt sleeve. For example,
As disclosed in JP-B-61-34574, after a plurality of V-belts are installed in a belt holding section, a support is rotated, and the belt alone automatically fed from the belt holding section is used as a belt holding section. And the belt alone is slid with the inclined belt insertion guide to
It is designed to fit into a pulley.

Further, Japanese Patent Publication No. 2-48777 discloses that
After installing the V-belt on the belt holding unit, automatically rotating the support column and moving the belt holding unit to just below the belt pushing unit, the belt holding unit is raised, and the belt group is sequentially moved in parallel, It describes that a belt carrier can pinch and fix a single belt located in the front row of the belt group and move it to a position directly above a pulley, and drop the belt at this position to fit the belt into the pulley.

[0005]

However, the conventional apparatus is an apparatus which can automatically fit the belt alone into the pulley, and cannot be applied to the belt sleeve.
For this reason, there has been a strong demand for the development of a device that can automatically insert and install a belt sleeve on a shaft of a processing device. Further, in the belt sleeve automatic insertion device described in Japanese Patent Application No. 8-219265, the center of the opening of the belt sleeve and the center of the shaft must be aligned because the shaft supporting the belt sleeve is two shafts. There was no. However, with the downsizing of the processing equipment, the number of processing equipments with one axis is increasing, and in order to use a mandrel whose diameter is almost the same as the diameter of the belt sleeve, the center of the opening of the belt sleeve and the axis The belt sleeve could not be inserted smoothly into the shaft unless it was aligned with the center. The present invention has been made to solve such a problem, and the center of the shaft of the processing apparatus coincides with the center of the belt sleeve in an opened state, and the center of the processing apparatus is conveyed and automatically transferred to the processing apparatus axis. It is an object of the present invention to provide an apparatus and a method for automatically inserting a belt sleeve to be inserted and installed.

Further, as the toothed pulley 8, a pulley having a tooth shape of S8M type and having 20 teeth was used. And
When this belt sleeve is raised and the limit switch is lowered, the limit switch contacts the top end of the belt sleeve,
Continue until detection.

When the limit switch 3 detects the uppermost end of the belt sleeve and stops lifting the belt sleeve, the rodless cylinder 15 is operated, and the push plate 16 pushes the belt sleeve 2 deep into the shaft 11 of the processing device 14. insert. At this time, the center of the belt sleeve and the center of the shaft 11 of the processing device 14 surely coincide with each other.

When the processing device 17 is a cutter device, the shaft 11 is a single shaft, and a cylindrical mandrel 22 made of a rubber sheet covers the periphery of the shaft 11. Then, the air cylinder 24 is actuated to push the expand mandrel 20 with the tail stop 25 and the rotation center 18, and the expand mandrel 20 and the rubber sleeve 22 are pressed.
Inflate. Then, after the belt sleeve 2 is fixed, the shaft 11 is rotated to cut the belt sleeve 2 into a belt having a trapezoidal cross section or an annular belt having a predetermined width.
