得るという実用的に効果がある。(Effect of the invention) As described above, according to the invention, there is provided a pair of left and right feed bars that can move up and down and back and forth relative to a series of press molding dies, and a pair of left and right feed bars that are installed with a predetermined interval between the feed bars. In a press conveying device for a transfer press, which is equipped with a large number of cross bars configured to convey press work, each of the cross bars is rotatably pivoted at predetermined intervals in the direction in which the cross bars extend. A plurality of supported pinion members and a work suction means configured to be engaged with each of the pinion members from both directions perpendicular to the workpiece feeding direction so as to be movable in opposite directions and capable of suctioning the press work. A common rack arm is connected to one end of the rack arm, and is connected to one end of the rack arm, and is connected to one end of the rack arm, and is connected to one end of the rack arm, and is connected to one end of the rack arm, and is connected to one end of the rack arm, and is connected to one end of the rack arm, and is connected to one end of the rack arm, and is connected to one end of the rack arm, and is connected to one end of the rack arm, and is connected to one end of the rack arm, and is connected to one end of the rack arm, and is connected to one end of the rack arm, and is connected to one end of the rack arm, and is connected to one end of the rack arm, and is connected to one end of the rack arm. A cylinder is provided for advancing and retracting the rack arm in the direction of protruding during transportation and retracting during work press forming, and a pinion member that is rotated by the forward and backward movement of the rack arm accompanying the operation of the cylinder allows the work suction means to be attached to the end. The rack member is made to protrude when transporting the workpiece, and is retracted during workpiece press forming, so the position of the workpiece suction means during workpiece press forming is much closer to the crossbar than during workpiece transport. Even if the installation space between molds becomes narrower, the press equipment and suction means will not inadvertently interfere with each other, and the space between adjacent molds can be made as narrow as possible, reducing the space occupied by the equipment. This has the practical effect of reducing the size of the area.

いう効果もある。 Furthermore, since each means (i.e., a pinion member, a rack arm, and a cylinder) constituting a mechanism for operating rack members equipped with workpiece adsorption means in opposite directions, is arranged on the crossbar, This greatly contributes to making the entire device more compact, and since one pinion member can simultaneously move two rack members in opposite directions, it also has the effect of simplifying the structure and reducing weight.
