Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet material conveying method and apparatus, and more particularly, to a sheet material such as a steel carcass as a tire constituent material, which is cut to a constant length and conveyed to the next step. The present invention relates to a method of conveying a sheet-shaped material and a device therefor.

[0002]

2. Description of the Related Art Conventionally, when a sheet-shaped material such as a steel carcass as a tire constituent material is conveyed, it is cut into a predetermined length by a cutting device in a carrying-in step, and the cut sheet-shaped material is orthogonal to the carrying-in direction. A method is used in which the sheet is conveyed in the direction of the following and is joined by a joining device in the next step.

For example, as shown in FIG. 4, a sheet-shaped material W such as a steel carcass is carried in from a carrying-in direction X onto a carrying-in table 1 installed in a direction orthogonal to the carrying-in direction, and cutting (not shown) at a cutting position S is carried out. The sheet-shaped material Wa cut to a fixed length by the device is sucked and conveyed by the suction / conveyance device 2.
Thus, the upper surface of the sheet-shaped material Wa is suction-held and conveyed to the position of the joining device 3 which is the next step.

As another conventional example, as shown in FIG. 5, a loading table 1a having a cutting device (not shown) for cutting the sheet material W in the loading direction X to a fixed length is installed. , A plurality of narrow belts installed in a direction orthogonal to the loading direction X of the sheet material W via the suction / conveying device 2 are transferred onto a narrow belt conveyor 4 arranged at predetermined intervals. The narrow belt conveyor 4 conveys the belt to the position of the joining device 3 in the next step.

That is, according to the conventional method for conveying the sheet-shaped material W, when the sheet-shaped material W is cut, the cutting angle is about 9 when the sheet-shaped material Wa is conveyed to the joining device 3 in the next step.
In the case of 0 ° to 40 °, it may be difficult to feed the sheet material Wa with a general belt conveyor due to the rigidity of the sheet material Wa, that is, the rigidity with respect to the traveling direction of the sheet material Wa. A narrow belt conveyor in which the above are arranged at a predetermined interval, and a transfer device equipped with a suction means are used.

[0006]

However, in the narrow belt conveyor as described above, it is difficult to directly carry the sheet-shaped material, which has been cut into the standard length, onto the narrow belt conveyor, so that another transfer is eventually performed. There is a problem that a device is required, the device is complicated, and a large space is required. Further, in the case of the conventional suction / conveyance device, since the upper surface of the sheet-shaped material is sucked and lifted, a trouble may be caused by a suction error or the like. There is a problem that it is impossible to carry out the work, and efficient work cannot be carried out due to the interference of operations.

The present invention was devised in view of the above-mentioned conventional problems, and it is possible to directly carry a sheet material that has been cut to a fixed length onto a narrow belt conveyor, and it is possible to simply and save space. It is an object of the present invention to provide a sheet material transport method and apparatus capable of performing efficient transport work.

[0008]

In order to achieve the above object, the present invention provides a plurality of narrow belts at predetermined intervals in a direction orthogonal to the sheet material carrying-in direction through a sheet material cutting device. A narrow belt conveyor arranged with a space between the narrow belt is installed, and a material receiving device and a material adsorbing means capable of moving up and down are installed below the narrow belts, and the narrow belt conveyor, the material receiving device and the material adsorbing means are installed. The gist of the present invention is to provide a transfer device for moving the cutting device in a direction away from the cutting position.

[0009]

The present invention is constructed as described above, and the material receiving device installed between the narrow belts of the narrow belt conveyor is elevated to a position slightly higher than the upper surface of each narrow belt. After the sheet material is ready to be loaded, the sheet material is loaded onto the narrow belt conveyor and the material receiving device for a predetermined length from the loading direction orthogonal to the narrow belt conveyor, and the sheet material is loaded. After the completion, the material suction means installed below each narrow belt of the narrow belt conveyor is lifted to suck and hold the lower surface of the sheet-shaped material that has been carried in, near the side edge of the narrow belt conveyor. The sheet material is cut to a standard length by the cutting device installed in
After the completion of cutting, the material receiving device holding the sheet material and the material adsorbing means are slightly moved in the direction in which the sheet material separates from the cutting blade of the cutting device, and then the material receiving apparatus and the material adsorbing means are narrow belt conveyor. After descending from the upper surface of, the fixed-width cut sheet-like material is transferred onto the narrow belt conveyor, and then the fixed-length cut sheet-like material is successively carried out to the next step by the narrow belt conveyor, In addition, there is no interference of operation, space can be saved, and efficient transfer work can be performed.
