ABSTRACT:
They consist of an adjustable mechanism to feed the cardboard sheets with which boxes are formed and of a lifting device of the laps that said cardboard sheets have.
The purpose of the adjustable mechanism for the feeding of the sheets is to adjust the position of the vacuum suction pads for the feeding of the cardboard sheets, whatever the dimensions thereof are, without the need to stop the assembly machine. For this reason, the groups of suction pads have their supports resting on two split contrary thread spindles, in such a way that with a single manual control and connecting both spindles by chain transmission displacement thereof is obtained all along the guide bars, thus establishing the work position of said suction pads.
The purpose of the lap lifting device is to automatically effect the lifting of the laps to the predetermined angular position. For this reaon it comprises a strip, tiltable by the action of pneumatic cylinders, which through their action of a shaft, to which the arms of the strip are joined, push the laps to their predetermined position. It comprises a means of approximation or separation in accordance with the format or dimensions of the laps.
