はるかに高速で搬送される。(Effects of the Invention) In the pitch conveyance device of the present invention, the movable body equipped with the conveyance jig is moved by the movable rack, the fixed rack, and the first pinion at a movement iit and speed twice that of the first pinion, and the first pinion The second pinion connected via the link member causes the reciprocating drive mechanism's stroke [1-up] to move with a large amount of movement and speed, so the movable body can be moved at a much larger stroke and speed than the reciprocating drive mechanism. Can be moved. In addition, since the initial position and stop position of the other end of the link member connected to the second pinion are set to move in the opposite direction with respect to the second pinion when starting up and when stopping, the first pinion The amount of movement near the time of start-up and stop is smaller than the stroke of the reciprocating drive mechanism, the speed of the first pinion is correspondingly lower, and the movable body is also moved at a lower speed. Therefore, although the conveyed article is conveyed at a low speed when rising and stopping, the conveyed article is conveyed at a much higher speed than the reciprocating drive mechanism as a whole.

The apparatus as a whole is compact, and even when the conveyance stroke is set to be large, the apparatus can be constructed compactly without particularly increasing the amount of movement of each of the above members.

送装置。(1) A pitch conveyance device that conveys conveyed articles in pitch along a conveyance path, which includes a movable body provided with a conveyance jig that is movable along the conveyance path and engages with the conveyed article; a movable rack fixedly installed on the body; a fixed rack opposite the movable rack and fixedly installed along the transport path; a first pinion meshed with the movable rack and the fixed rack; and the first pinion. The first
a movable base, a second pinion meshed only with the fixed rack, a second movable base that rotatably supports the second pinion and is movable along the transport path, and a second movable base. The other end of the link member includes a reciprocating drive mechanism that reciprocates the table at a constant stroke, and a link member whose one end is pivotally supported by the first movable table and whose other end is pivotally supported at an eccentric position of a second pinion. The initial position is set at a position where the displacement of the second movable base in the moving direction is in the opposite direction to the above-mentioned moving direction with respect to the second movable base while the second movable base moves a predetermined distance after the second movable base starts moving. Then, while the second movable base moves a predetermined distance just before stopping, the stop position is set at a position where the displacement of the second movable base in the moving direction is opposite to the moving direction with respect to the second movable base. A pitch conveying device characterized by:
