切断片を送出し。(Prior Art) As a ply supply device for a tire molding machine for primary forming radial tires, it is known that a belt conveyor is provided in front of the top of the molding drum of the tire molding machine in the direction of the cutting line. . Conventionally, when performing the above primary forming, a long carcass ply raw fabric consisting of a large number of cords in the width direction and a rubber layer covering these cords is prepared in advance, and this carcass ply raw fabric is transferred to the belt conveyor. At the top, cut the molding drum to a length slightly longer than one circumference, and then move the belt conveyor together with its support frame so that the delivery side end of the belt conveyor near the molding drum is attached to the top of the molding drum. Then, the belt conveyor is rotated to send out the cut pieces of the carcass ply.

成していた。The tip is guided to the top of the molding drum and fixed, and the molding drum is further rotated to wrap the cut pieces of carcass ply on its surface. After one rotation of the molding drum, the rotation is stopped and the cut pieces are wrapped around the top of the molding drum. For winding, the end of the winding was stacked on the end and pressed, thereby bonding and connecting both ends to form an endless carcass ply.

過不足が一層大きくなるという問題があった。(Problems to be Solved by the Invention) However, since the above-mentioned carcass ply raw material has a large number of cords in the width direction, distortion due to internal stress is generated to a greater extent than in a belt-like body made only of rubber. Cutting tends to cause expansion and contraction, and in the past, much of the work was done manually by workers, so there was a large variation in the cut length of the material, and there was also a synchronization failure when the cut pieces of the carcass ply were transferred from the conveyor to the forming drum. This tends to occur, and as a result, there have been problems such as excess or deficiency in the overlap of the joined portions of the cut pieces, deviation of the overlap from left to right, or inclination. In addition, the carcass ply material is cut to a predetermined length on a conveyor,
The cut pieces are then wrapped around a molding drum, so a rubber sheet is pasted on the molding drum as a liner to help the ply adhere.If the rubber sheet has uneven thickness or unevenness, However, there was a problem in that the excess or deficiency of the above-mentioned overlapping allowance became even larger.

のないプライ供給装置を提供するものである。In this invention, the carcass ply is always mechanically restrained to prevent free shrinkage or shrinkage of the carcass ply, and the winding of the carcass ply is performed by minimizing the excess or deficiency of overlap between the ends and the end of the winding. To provide a ply supply device that does not shift laterally or tilt.

表面にカーカスプライ原反を巻付ける。In synchronization with this, the two slide tables mentioned above are advanced toward the drum side, and the tip of the ply, which is attracted to the vacuum pad of the slide table on the conveyor side, is conveyed to the top of the forming drum. The ply is crimped onto the top of the forming drum, then the conveyor-side vacuum pad releases the adsorption of the ply tip, the vacuum pads on both the drum side and the conveyor side are switched to the upper position, and the forming drum is rotated to place the carcass on its surface. Wrap the ply material.

て成形用ドラムの表面に凹凸が生じていたり。(Effects of the Invention) This invention has two sliding tables arranged one behind the other, and a vacuum pad attached to the sliding table on the conveyor side to suck and hold the tip of the carcass ply material (the winding start end). The molding drum is conveyed to the top of the molding drum while rotating, and then the conveyor-side slide table is moved back and the carcass ply material is cut between the drum-side slide table and the conveyor-side slide table. The rear end (end of winding) of the carcass ply cut piece connected to the forming drum is sucked and held on the vacuum pad on the drum side sliding table, and carried to the top of the forming drum while rotating the forming drum again, and 5 turns are attached. The starting end is overlapped with the ending end of the roll and crimped. After wrapping most of the length required for winding the carcass ply material around the forming drum, Since it is designed to be cut to length, a liner made of rubber sheet is pasted on the surface of the molding drum in advance, resulting in unevenness on the surface of the molding drum.

でき。Even if the circumference of the forming drum is large (or even if it varies), the carcass ply material can be cut accurately to the required length.Also, while the carcass ply material is being conveyed on a conveyor, The leading end of the carcass ply is suctioned by a vacuum pad and conveyed toward the top of the forming drum, and the rear end of the cut carcass ply piece after being cut is suctioned and held by a vacuum pad while being conveyed while rotating the forming drum. Since the above-mentioned cut pieces are wrapped, by synchronizing the feed speed of the vacuum pad with the speed of the conveyor and the speed of the belt forming drum, fluctuations in the tension on the carcass ply material and its cut pieces are eliminated and uneven expansion and contraction is achieved. This eliminates the problem of winding, making it possible to align the overlap between the end and the end of the winding evenly, and prevent the overlapping from shifting or tilting.In addition, the front and back of the cut part of the carcass ply material is suctioned with a vacuum pad, Since the drum side of the cutting section is suctioned and held until the winding is completed, and the opposite conveyor side is held by suction until the next winding, deformation, shrinkage, etc. after cutting the carcass ply material are prevented. If the entire ply supply conveyor is formed so as to be close to the forming drum, the length of the carcass ply material that is wound around the forming drum before cutting the carcass ply material is set to be long. It is possible.
そのためカーカスプライ原反の切断長さを一層正確にす
ることができる。Therefore, the cutting length of the carcass ply material can be made more accurate.
