BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for correcting meandering of a belt-shaped material from a supply cart and an apparatus therefor, and more particularly, when the liner meanders when winding or unwinding the belt-shaped material. From a supply cart that can automatically detect the meandering by a meandering correction device provided on the winding drive unit side or the unwinding drive unit side and automatically correct it by a meandering correction mechanism provided on the supply cart. The present invention relates to a method for correcting meandering of a band-shaped material and a device therefor.

2. Description of the Related Art Conventionally, when a strip-shaped material such as a rubber sheet is wound on a member winding cell provided on a supply carriage or is unwound to a molding machine side, a liner cell installed on the supply carriage is used. A method of unwinding the liner or winding the liner into a liner cell is used. By the way, since the starter and the end of the liner provided on the supply cart are fixed to the member winding cell and the liner cell, there is no major meandering factor in unwinding and winding, but the unwinding of the liner And when the winding is repeated, there is a problem that the meandering gradually grows and the winding of the liner collapses, so that the winding and unwinding of the strip-shaped material on the supply carriage cannot be performed smoothly. .

[0003]

Therefore, conventionally, there has been proposed a device provided with a centering mechanism of a liner, a meandering correction device or the like on a guide flange or the like on the device side near the stop position of the supply cart. However, there is a problem that the device becomes complicated and large in size, and further, the liner needs to be hung around the centering mechanism and the meandering correction device of the device one by one, which requires a lot of labor and time. .

The present invention has been devised in view of the above-mentioned conventional problems. By making it possible to automatically correct the meandering of the liner on the supply carriage, the apparatus does not become complicated. Another object of the present invention is to provide a meandering correction method and device for a belt-shaped material feeding carriage that can be made lighter and more compact, and that can improve workability.

[0005]

In order to achieve the above object, the present invention has a member take-up cell and a liner cell installed in parallel on a supply cart, and the member take-up cell and the liner cell are provided between the member take-up cell and the liner cell. On the supply cart, the meandering correction roll of the liner is installed in parallel with the member winding cell and the liner cell, and on the winding driving device side or the unwinding driving device side, an edge sensor that detects the widthwise edge of the liner, The gist of the present invention is to install an elevating means for elevating and lowering the end portion of the meandering correction roll based on the signal from the edge sensor.

Further, the meandering correction roll is supported via an elastic member so as to be kept in parallel at all times, and the meandering correction roll is connected to an elevating means via an arm mechanism.

[0007]

The present invention is constructed as described above, and when the band-shaped material is wound on or unwound from the member winding cell installed on the supply carriage, the liner is unwound or liner cell is unwound from the liner cell. When winding, the edge sensor installed on the winding or unwinding drive side detects the meandering state of the liner, and based on the signal from this edge sensor, it is installed in parallel between the member winding cell and the liner cell. The liner meandering can be made compact and lightweight by lifting and lowering one of the end portions of the meandering correction roll through the elevating means to correct the liner meandering. The state can be automatically detected and the meandering correction can be automatically performed, and the workability can be improved.
