DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for laminating sheet-like materials, and more particularly, to a laminating sheet for laminating a sheet-like material conveyed on a laminating conveyor. TECHNICAL FIELD The present invention relates to a method and an apparatus for bonding a sheet-like material capable of accurately detecting the width of a sheet-like material and improving the bonding accuracy.

[0002]

2. Description of the Related Art Conventionally, as a method of bonding a sheet material such as a rubber sheet, for example, a method in a calendering step or a method in which the material is once wound up in a roll with a liner and then unwound again. is there. The latter method of unwinding is performed by using an unwinding roll for a sheet-like material Wa (for example, a carcass as a tire constituent material) conveyed on the laminating conveyor 1 as shown in FIG. 2, the sheet material W is unwound together with the liner R, and the sheet material W is directly transferred to and adhered to the sheet material Wa to be bonded via the press roll 3.

[0003]

However, the above-mentioned method of unwinding and unwinding is not suitable for unwinding the sheet-like material W at the time of unwinding.
The width change is likely to occur due to uneven contact between the liner and the liner R,
In order to avoid this, a method of transferring each liner R is adopted. However, the only way to adjust the bonding position and to improve the bonding accuracy is to detect and control using a detection device 4 such as an edge position control (EPC) in a state where the bonding is performed on the liner R. There is a problem that the responsiveness of the position adjustment control and the reliability of the bonding accuracy are lacking.

In FIG. 7, reference numeral 5 denotes a carcass guide roll, and reference numeral 6 denotes a liner winding roll. The present invention has been devised in view of such a conventional problem. By detecting the width of the laminated sheet material after the liner is removed, the width detection accuracy is improved, and the laminated sheet shape is improved. Since the detection of the width of the material and the lamination position can be close, the response of the control is good and the lamination accuracy can be improved. It is an object of the present invention to provide a method for bonding sheet-like materials and an apparatus therefor which can be used as an inexpensive system device with no machine difference because the positions are the same.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a transfer conveyor slidable on a laminating conveyor for transporting a sheet-like material to be laminated in a direction perpendicular to the conveying direction of the laminating conveyor. Is installed, and an unwinding roll and a liner winding roll of the laminated sheet material are installed on the transfer conveyor, and the width of the laminated sheet material is detected at the sheet material laminating position in front of the transfer conveyor. And a driving means for adjusting the position of the transfer conveyor in the width direction is connected via a control device.

[0006]

According to the present invention, the laminated sheet material is unwound together with the liner from an unwinding roll onto a transfer conveyor, and the liner is peeled off from the laminated sheet material. The transfer material is conveyed to a bonding position by a transfer conveyor, the width of the bonded sheet material is detected by a width detection sensor immediately before bonding, and the transfer conveyor is moved in the width direction based on a width detection signal from the width detection sensor. After being moved to control the position of the laminated sheet material in the width direction, the laminated sheet material is laminated on the surface of the laminated sheet material conveyed on the laminating conveyor. The width of the laminated sheet material to be laminated to the laminated sheet material conveyed on the laminating conveyor can be accurately detected to improve lamination accuracy. Than it is.

Reference numeral 31 denotes a pressing roll for pressing the bonded sheet material W onto the transfer conveyor 11 for bonding. The bonded sheet material W and the liner R unwound from the unwinding roll 12a are pressed. At the time of passing through the roll 31, the laminated sheet-like material W moves along the transfer direction of the transfer conveyor 11, and the liner R is wound around the liner winding roll 12b.

Unwound from the winding device 24a and the laminated sheet material W
In the case of bonding, the bonded sheet material W is unwound onto the transfer conveyor 11 together with the liner R from the unwinding roll 12a.

Then, the laminated sheet material W and the liner R unwound from the unwinding roll 12a are peeled off when passing through the holding roll 31, and the laminated sheet material W
Is transported along the transport direction of the transfer conveyor 11, and the liner R is wound up by a liner winding roll 12b. After the liner R is peeled off from the laminated sheet material W in this manner, the laminated sheet material W is transported to the laminating position P by the transfer conveyor 11, and is centered by the centering mechanism 35, and then laminated. Immediately before joining, both side edges of the laminated sheet material W are detected by the optical detector by the width detection sensor 13 and the center of the width of the laminated sheet material W is obtained by the arithmetic unit of the control device.

According to the present invention, since the width of only the laminated sheet material after the liner is removed is detected and laminated, the width detection accuracy is improved, and the laminated sheet is improved. Since the detection of the width of the sheet material and the bonding position are close, the response of the position control is good, and even if a plurality of unwinding devices for the bonded sheet material W are arranged, the bonding position is the same. In addition, it is possible to provide an inexpensive system device with no machine difference, and since there is no meandering of the liner winding, the liner can be wound accurately.
