ABSTRACT:
A multiple automatic packing machine packs a material by continuously and repeatedly slitting a wide sheet-like packing material into a predetermined number of packing films fed from a take-up roll, seal-molding each of the packing films into a bag-like configuration by a vertical sealer and a lateral sealer, filling the material to be packed into each of the packing films, withdrawing each of the packing films by lowering the lateral sealer a portion equal to the length of the bag to be formed, raising the lowered lateral sealer back to a location before the lateral sealing by laterally opening the lateral sealer, and cutting a center line portion of the lateral seal of each of the packing films. The machine includes a performance controller for the multiple automatic packing machine, the controller having a program input for setting the number of rotation of a motor for upwardly/downwardly driving the lateral sealer and the timings of operation of the filling device and a cutter driving device for each size of a product to be sealed, a key input for selecting a size number of the product to be sealed, and a control unit for controlling the number of rotations of the upwardly/downwardly driving motor and the timings of operation of the filling device and the cutter driving device, in accordance with a program for a size number selected by the key input.
