Patent number: 11278017Abstract: An automatic fishing system includes a plurality of fishing machines each of which has rotation drums capable of winding fishing lines and capable of rotating in a reeling direction and an unreeling direction, a drive motor for driving the rotation drums in the reeling direction and the unreeling direction, and an electromagnetic clutch for transmitting rotation of the drive motor to the rotation drums, a hooking detection means for always detecting hooking of fish at any one of the plurality of fishing machines, and a fishing machine control means for controlling operations of the plurality of fishing machines in accordance with detection result of the hooking detection means. The fishing machine control means controls the rotation drums of other fishing machines that hook no fish in the reeling direction so that hooks of the other fishing machines are wound up to a water surface or near the water surface.Type: GrantFiled: December 12, 2019Date of Patent: March 22, 2022Assignee: TOWA DENKI SEISAKUSYO CO., LTD.Inventors: Yuichi Hamade, Tomohiro Miki

Patent number: 10888077Abstract: 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.Type: GrantFiled: May 15, 2017Date of Patent: January 12, 2021Assignee: TOWA DENKI SEISAKUSHO CO., LTD.Inventors: Yuichi Hamade, Daigo Sawada, Tomohiro Miki, Eri Hamade

Patent number: 10813347Abstract: A fishing machine includes a rotary drum for winding a fishing line, capable of rotating in a reeling direction and in a unreeling direction, a drive motor for rotating the rotary drum in the reeling direction and in the unreeling direction, and an electromagnetic clutch for transmitting the rotation of the drive motor to the rotary drum. The electromagnetic clutch is capable of variably setting a transmitting torque of rotation, and the transmitting torque is set to a value for cancelling a mechanical load in the unreeling direction of the fishing machine.Type: GrantFiled: December 12, 2018Date of Patent: October 27, 2020Assignee: TOWA DENKI SEISAKUSYO CO., LTD.Inventors: Yuichi Hamade, Tomohiro Miki, Manabu Tamamori, Kohei Watanabe
