MACHINE AND METHOD FOR ASSEMBLING BOXES

摘要

The invention relates to a machine for assembling boxes of the type that comprise four independent parts, namely: two head walls, two side walls and a base provided with peripheral flanges that engage with grooves provided in the lower portion of the side walls and head walls. In addition, the ends are provided with end tongues that are inserted into notches provided close to the ends of the sides. The machine includes a central assembly station (1) comprising a base ring (10) inside which a stationary forming die (11) is disposed. The base of the box (2) to be formed is positioned on the lower face of the die, such that, while the base is held in position, horizontal push devices are activated which move the head walls (4) and the side walls (3) towards the base (5) which is locked in position against the lower face of the stationary forming die (11).

主权项

1. Machine for assembling boxes, the boxes being of the type that comprise five independent parts made of a rigid material: two side walls, two head walls and a base provided with peripheral flanges that engage with grooves provided in the lower portion of the side walls and head walls, the head walls being provided with end tongues that are inserted into notches provided close to the ends of the side walls; the machine integrating a central assembly station of the boxes which comprises:
four feeders of the side walls and head walls facing each other two by two; moving means that move the side walls and head walls from the feeders to the lateral edges of the base in the final step of assembly of the box,characterized in that the central assembly station (1) also comprises:
a base ring (10) inside which a stationary forming die (11) is arranged, where on its lower face the base (5) of the box (2) to be formed is placed by means of a lifting device (12) with vertical mobility in both directions, which moves the base (5) upwards from a lower position to an upper position against the stationary forming die (11) in a first performance, the peripheral flanges (6) protruding from the base (5) with respect to the perimeter of the stationary forming die (11).
