Description

Conveying device Technical Field The present invention relates to a conveying device. Background Conventionally, there is a technique for suppressing meandering of a long member in a conveying device for conveying the long member. For example, in patent document 1, in order to suppress meandering, the shape and the material of a support member provided in a peeling roller are studied. Patent document 1 Japanese patent application laid-open No. 2017-206344 Disclosure of Invention However, it is difficult to completely eliminate occurrence of hunting. The present invention can be implemented in the following manner. (1) According to one aspect of the present invention, there is provided a conveying apparatus that conveys a long-sized member of a long size in a conveying direction. The conveying device includes a movable clamp that conveys the long member by moving in the conveying direction while sandwiching the long member, a1 st sensor that is disposed upstream of the movable clamp in the conveying direction and detects a widthwise displacement of the long member, a cutting blade that is disposed downstream of the movable clamp in the conveying direction, and a control unit that performs 1 st control of determining a meandering section in which the displacement occurs in the long member using the 1 st sensor and causing the cutting blade to cut the long member at a downstream end of a meandering range including the meandering section and an upstream end of the meandering range, respectively. According to this aspect, the hunting region including the hunting region is cut off, whereby the hunting region can be cut off. By not using the cut-out meandering segment in the product, product defects caused by the meandering segment can be prevented. (2) The above-described conveying device may further include a2 nd sensor that is disposed upstream of the movable clamp in the conveying direction and detects the adhesive tape included in the long member, and a fixed clamp that is disposed between the movable clamp and the cutting blade and fixes the long member at least while the cutting blade cuts the long member, wherein the control unit is configured to control the long member to be conveyed to a position where the adhesive tape does not overlap with a1 st clamping position of the movable clamp and to convey the long member to a position where the adhesive tape does not overlap with a2 nd clamping position of the fixed clamp when the 2 nd sensor detects the adhesive tape. If the adhesive tape is held by the movable jig, the adhesive substance may adhere to the movable jig, and the quality of the long member may be degraded. The same applies to the fixing jig. Therefore, according to this aspect, the adhesive tape can be prevented from being held by the movable jig and the fixed jig. Therefore, degradation of the quality of the long-sized member can be prevented. (3) In the above-described aspect of the conveying apparatus, the control unit may perform the 1 st control when the adhesive tape is positioned on the downstream side of the meandering section and the distance between the adhesive tape and the meandering section is equal to or longer than a predetermined 1 st reference length, perform a3 rd control of conveying the long member so that the downstream end of the adhesive tape moves to the 2 nd position on the upstream side of the meandering section in the conveying direction in the 1 st control, and perform a3 rd control of cutting the long member so that the downstream end of the adhesive tape moves to the 1 st position on the upstream side of the meandering section in the conveying direction in the 2 nd control, and perform a3 rd control of cutting the long member so that the downstream end of the adhesive tape moves to the 2 nd position on the upstream side of the meandering section in the conveying direction in the 3 nd control in the conveying direction in the downstream end of the meandering section in the 3 nd control in the conveying direction in the downstream side of the meandering section in the conveying direction in the cutting section. According to this aspect, by performing the cutting of the long members at the upstream end and the downstream end of the meandering section, respectively, in the 1 st control, the length of the discarded long members can be suppressed. Therefore, the manufacturing cost can be reduced. Further, by setting the 1 st reference length to the product length, when the product member cannot be cut, the 4 th control is performed to continuously discard the adhesive tape and the meandering section, whereby the cutting step at the downstream end of the meandering section can be omitted, and the control can be simplified. (4) In the above-described aspect of the conveying device, the control unit may perform the 1 st control in which the cutting blade is caused to perform cutting of the long member at the downstream end of the winding section and the upstream end of the w
