Abstract: A counter ejector has: a ledge that moves toward an inner side of a hopper to receive boxes S in the hopper when the boxes accumulated in the hopper reach the predetermined number; a press bar that is disposed so as to move vertically relative to the ledge, and presses the batch on the elevator by moving vertically downward relative to the ledge; and a relative movement servo motor that moves the press bar vertically relative to the ledge. The press bar is driven by the relative movement servo motor to vertically move relative to the ledge.

Abstract: A nonconforming product removing unit is disposed between a folding unit and a counter ejector of a box making machine, and includes a sort-out unit that conveys a corrugated board box whose joint is judged to be good by a judging unit to the counter ejector, and on the other hand discharges a corrugated board box whose joint is judged to be bad by the judging unit. Accordingly, only the conforming corrugated board box can be conveyed to the counter ejector. Therefore, the nonconforming board box can be removed easily, without requiring complicated work of taking out the nonconforming corrugated board box from among corrugated board boxes sorted into a predetermined number of batches by the counter ejector, and re-sorting only the conforming corrugated board boxes into a predetermined number of batches.

Abstract: A sheet-fed duplex printing press includes a front-surface printing unit having a first impression cylinder that can carry cut paper by rotating while holding the cut paper a first blanket cylinder that contacts the first impression cylinder and can transfer heatset ink onto a front surface of the cut paper, and a first ink jet head that can supply the heatset ink to the first blanket cylinder, and a rear-surface printing unit having a second impression cylinder that can carry the cut paper by rotating while holding the cut paper, a second blanket cylinder that contacts the second impression cylinder and can transfer heatset ink onto a rear surface of the cut paper, and a second ink jet head that can supply the heatset ink to the second blanket cylinder, in which the first impression cylinder and the second impression cylinder directly contact each other.

Abstract: In a driving device for a plate-shaped body feeding kicker, a durability of a slide section is improved and mixing of paper powder onto a slide surface can be prevented by supporting a rear end of a screw shaft for moving the kicker by use of a block encompassed by a guide cylinder. In more particular, a front end of a screw shaft for reciprocating a kicker is supported by a slider similarly to the driving device in the prior art, but the rear end of the screw shaft is supported by slidably encompassing a slide piece mounted to the screw shaft by means of a guide cylinder. Especially, the slide piece is held within the guide cylinder as immersed in oil.
