  • Publication number: 20110173803
    Abstract: A self-piercing rivet setting machine comprises a C-shaped arm and a receiver section disposed at one end of the C-shaped arm to receive a self-piercing rivet fed from a feeder. The receiver section has a rivet-reach detection sensor to detect the presence or absence of a self-piercing rivet in a driving chamber therein. If the rivet-reach detection sensor detects the absence of any self-piercing rivet in the driving chamber, the sensor outputs a signal to prevent a punch from being driven.

  • Patent number: 7861498
    Abstract: When the articles dropping from above are received inside a hopper, at least a bottom portion of the hopper is allowed to move downwardly with the bottom portion of the hopper being closed. Therefore, the collision speed between the articles and the bottom portion of the hopper is reduced. In addition, by opening the bottom portion of the hopper while moving the bottom portion downwardly, the downward initial speed is added to the articles to be discharged.
