Title: Improvements to machines for lifting cardboard boxes
Inventor: JOSE BOIX JAEN
IPC: B31B50/06
Filed: 1992-04-28
Abstract: This is an adjustable mechanism intended for supplying cardboard panels (boards) with which the boxes are made, and a device for lifting the reverse of the said panels. The object of the adjustable mechanism for supplying the panels is to adjust the position of the discharge suction pads for the supply of cardboard panels, regardless of the dimensions of the latter, without having to stop the operation of the lifting machine. To this end, the groups of suction pads have their supports which rest on two divided spindles (arbors) of contrary screw thread, so that, with a single manual command and connecting the two spindles by chain transmission, a displacement is obtained right along guide bars, thus establishing the working position of the suction pads. The objective of the reverse-side lifting device is to automatically produce the lifting of the reverse side as far as the predetermined angular position. To this end, the device comprises a rule, tilting through the action of pneumatic cylinders, which, actuated on a shaft to which the arms of the rule are attached, push the reverse sides as far as their predetermined position. It comprises means for bringing together or separating in accordance with the format or the dimensions of the reverse sides.
