As a result, the front side holding member 13 and the rear side are moved. The carton C is transported on the transport surface 3 while maintaining the molding state by the holding member 14.
The carton C in the molded state is then subjected to required work at each work position such as the flap closing process set at a required position on the conveying surface 3 and the article storing process in the carton C.
When the carton C reaches the downstream end of the transport surface 3, the mover 12 provided with the front side holding member 13 and the rear side holding member 14 that holds the carton C is transported along the circulation path 11. It moves below the surface 3 and the mover 12 reaches the downstream end of the non-linear motor control section A2.
The control means recognizes the position of the movable element 12 by an encoder or a position sensor provided on the belt conveyor 17, and the engaging member 16 is detached from the movable element 12 to move to the linear motor control section A1. In order to form the carton C before the proper molding, it waits below the conveying surface 3.

According to the above embodiment, the linear motor control section A1 and the non-linear motor control section A2 are set in the circulation passage 11 in the molding / conveying means 6 for molding and transporting the carton C. It is not necessary to provide the electromagnet 15 in the control section A2, and the carton transport device 1 can be manufactured at low cost.
On the other hand, in the non-linear motor control section A2, the mover 12 engages with the engaging member 16 and moves while maintaining a predetermined interval. The position can be controlled.
In particular, in the carton transport device 11 in the present embodiment, the positions of the front side holding member 13 and the rear side holding member 14 are individually controlled in the linear motor control section A1, so that the carton C is changed from the state before molding to the molding state. In the non-linear motor control section A2, the front-side holding member 13 and the rear-side holding member 14 held at a predetermined interval can convey the molded carton C while maintaining the molding state. It has become.
That is, the front-side holding member 13 and the rear-side holding member 14 can be used as they are for molding and transporting the carton C, and the configuration of the carton transport device 1 can be simplified.
