Abstract: A pole-and-line fishing device includes a rotary drum, a drive motor, an electromagnetic clutch, an encoder for detecting direction and speed of rotation of the rotary drum, and a control unit for controlling the electromagnetic clutch. The drive motor can rotate the rotary drum in a forward winding direction until a load reaches a transmission torque, and when load exceeds the transmission torque, the drum can rotate in a reverse unwinding direction. In a reverse torque operation region, a winding torque is set to a preset Winding Force 2 Reference Rotation Speed relative to a Winding Force 1, and is changed based on a change of rotation speed of the drum. The ratio of winding torque increase/decrease is determined by a torque rising curve. The winding torque switches to Winding Force 3 to perform a constant torque operation when speed of the drum reaches Winding Force 3 Reference Rotation Speed.

Abstract: A chain for a vacuum conveyor, includes a plurality of links each having a flat front surface for placing a conveyance object and a back surface facing to a suction portion. A plurality of adsorption holes each having a large opening area on the front surface and a small opening area on the back surface is formed in the link.
