摘要： A press apparatus that allows more flexible design for a punch than the conventional technique is provided.
A workpiece feeding apparatus 45 (a press apparatus) of the present disclosure includes two, namely, first and second biasing mechanism 151, 152 for applying upward biasing force to a knockout pin 53. At the moment of press work, by the first punch 51 and the knockout pin 53 holding a workpiece 90 therebetween and shifting downward to a die 60, the knockout pin 53 receives biasing force from the first and second biasing mechanisms 151, 152 to press the workpiece 90 from below, so as to prevent the workpiece 90 from bulging deformation. Immediately after the press work on the workpiece 90, the first breaking mechanism 153 breaks transmission of biasing force from the first biasing mechanism 151 to the knockout pin 53. While being less pushed by the knockout pin 53, the workpiece 90 shifts down to the discharge position.

摘要： There are disclosed a conveying apparatus and a conveying system in which a force is efficiently transmitted to an article so as to smoothly convey the article in an arbitrary direction. In each of feed portions (15) provided at a conveying apparatus (10, 11) of the invention, a twist gear (34) is mounted on a twist base (16), and is disposed below feed rollers (17), and therefore the degree of freedom of the configurations of the twist gear (34) and feed rollers (17) are higher as compared with a conventional construction in which a feed roller is provided within a twist gear. Therefore, a compact design of the twist gear (34) can be achieved, and also the feed portions (15) and (15) can be disposed closer to each other as compared with the conventional construction. And besides, a large-size design of the feed rollers (17) can be achieved, so that an area of contact of the feed rollers (17) with the article can be increased. As a result, the force can be efficiently transmitted to the article (90) from each of feed portions so as to smoothly convey the article in an arbitrary direction.
