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.

Counter ejector and carton former

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.
