Zusammenfassung:The present invention relates to a box making machine including a box feeding part (10) consecutively feeding a plurality of corrugated cardboard boxes (1) folded in a flat shape and stood, in a state in which the boxes are in contact with each other on forward and backward positions, a separator (20) separating the corrugated cardboard boxes (1) fed from the box feeding part (10) one by one, and jaws (60) unfolding the corrugated cardboard boxes (1) separated by the separator (10), into a square container shape. The jaws (60) include: a support plate (70) having one end combined with a post (11) stood in front of the box feeding part (10) to be liftable such that the corrugated cardboard boxes (1) separated by the separator (20) are located on the front side thereof, and having a first combination pin (71) provided on the front side thereof to be inserted into troughs of the corrugated cardboard boxes (1); a rotary plate (80) having one end combined with the one end of the support plate (70) to be rotatable around a vertical rotation shaft (81) such that one side is opposed to the support plate (70); and a changeable plate (90) having one side combined with the one side of the rotary plate (80) to be selectively detachable, and having a second combination pin (92) provided on the other side to be inserted into the troughs of the corrugated cardboard boxes (1). Therefore, the present invention is capable of improving work convenience by enabling the changeable plate to be separated from the rotary plate through a simple system. 본 발명은 납작하게 접혀져서 직립된 복수의 골판지박스(1)를 전후로 밀착된 상태로 연속 공급하는 박스공급부(10)와, 이 박스공급부(10)에서 공급되는 골판지박스(1)를 하나씩 분리하는 세퍼레이터(20)와, 이 세퍼레이터(10)에서 분리된 골판지박스(1)를 사각통 형태로 펼치는 조우(60)를 포함하는 제함기에서, 상기 조우(60)는, 상기 세퍼레이터(20)에 의해 분리된 골판지박스(1)가 전면에 위치되도록 일측단이 상기 박스공급부(10)의 전방에서 직립된 포스트(11)에 승강가능하게 결합되며, 전면에는 골판지박스(1)의 골에 삽입되는 제1결합핀(71)이 구비된 지지플레이트(70); 일측단이 상기 지지플레이트(70)의 일측단에 수직회전축(81)을 중심으로 일면이 지지플레이트(70)와 마주보도록 회동가능하게 결합된 회동플레이트(80); 및 일면이 상기 회동플레이트(80)의 일면에 선택적으로 착탈가능하게 결합되며, 타면에는 골판지박스(1)의 골에 삽입되는 제2결합핀(92)이 구비된 가변플레이트(90);를 포함하는 것을 특징으로 하는 박스두께에 따라 가변가능한 제함기이다.
