  • Patent number: 10569374
    Abstract: Provided is a production facility (1), including: a plurality of production units (10A to 10E) coupled to each other in a separable manner; a guide rail (2) extending in a unit coupling direction; and transfer means (3) capable of sequentially transferring, by moving along the guide rail (2), a workpiece from the production unit (10A) toward the production unit (10E). Each of the plurality of production units (10A to 10E) includes: a processing section (13) configured to execute predetermined processing; a control section (14) configured to electrically control an operation of the processing section (13); a rail member (20) constructing the guide rail (2); and a slide member (30) constructing the transfer means (3). Each of the plurality of production units (10A to 10E) further includes: a connector (15, 15) configured to electrically connect the control section (14) thereof and the control section (14) of the adjacent production unit (10).

  • Patent number: 9993901
    Abstract: A boot band for fixing a boot that is mounted to a constant velocity universal joint is clamped. The boot band and the constant velocity universal joint are aligned in phase with each other in a circumferential direction. An axial position of a clamping portion is thereafter aligned with an axial position of the boot band. Then, the boot band is clamped by the clamping portion.

  • Publication number: 20140115857
    Abstract: Provided are a clamping method and a clamping device that enable automatic mount and fixation of a boot to a constant velocity universal joint with a band. A boot band (11) for fixing a boot (10) that is mounted to a constant velocity universal joint (S) is clamped. The boot band (11) and the constant velocity universal joint (S) are aligned in phase with each other in a circumferential direction, and an axial position of a clamping portion (13) of clamping means (12) is thereafter aligned with an axial position of the boot band (11). Then, the boot band (11) is clamped by the clamping means (12).
