One of SACMI divisions is specialized in production of machines for automatic tray forming dedicated especially for produce and bakery industry.
The tray forming cycle goes as follows: the suction cups pick up the blank from the horizontal magazine. The blank is then unloaded onto the guides and carried by the main chain, which is pushed from the rear, to a position underneath the hot-melt glue guns that apply the glue stitches indicated in the program. The blank is then transferred into the forming area and is perfectly centered where the cycle starts. The mold pushes the blank into the hopper. Strong pressure is then applied between the side flaps and the side of the tray being glued with the glue still hot during the forming piston’s stroke. The tray stops between the four spring stopping devices in order for the mold to come out easily. The top flaps are folded by four pneumatic cylinders (one for each corner to better follow the punching operation). Four side pressers fold and glue the flaps along the side of the box. During this operation, slight pressure is applied on the tray top flaps and the four pneumatic stopping devices at the bottom of the box to make sure the sizes and squaring are correct. The operating cycle is PLC-controlled, according to specific parameters previously set in the program with the color interface. Up to 80 sizes can be saved.
