Abstract
A device for achieving the separation or extension of the scale of products in a conveyance in superposed copies in which means are provided that are capable of increasing the speed of the belts (12, 17) conveying the separated or extended scale relative to the speed of the upstream belt (11) of the device for the conveyance of the scale before the separation or extension.
Claims8
A device for obtaining a separation or extension of the scale of products (2), consisting of signatures, paper or paperboard sheets, folded boxes and the like, in a conveyance in copies that are superposed in a scale-like fashion, characterized in that it comprises:
- a movable carriage (3), said carriage preferably moving with the same speed as the scale-fashion conveyor (1);
- means (15), that can be adjusted according to the dimension of the products that are to be retained, for the retention of the scale;
- means for changing the speed of the belts (11, 12, and 17) of the conveyor;
- means for uncoupling the speed of belts (12, 17) of the conveyor without interfering with the speeds of the upstream and downstream belts of the scale-fashion conveyor.
A device as claimed in any of the preceding claims, characterized in that the speed of belts (12, 17) increases upon intervention of a friction clutch (30) that is on a shaft (31), said shaft being coupled with the pulleys (32) of belt (12) and with the pulleys (36) on a shaft (35) of belt (17).
A device as claimed in any of the preceding claims, characterized in that during the displacement of carriage (3) from the starting position to the final one, in which the products (2) arranged in a scale fashion are separated, the length of belts (11, 12, 17) remains unchanged.
A device as claimed in any of the preceding claims, characterized in that the carriage (3) is coupled to a brake-clutch or motor device that causes its motion.
A device as claimed in any of the preceding claims, characterized in that a ratcheting device allows the rotational speed of the transmission assembly driving the belts (12 and 17) to be uncoupled when the speed increase of the same occurs.
A device as claimed in any of the preceding claims, characterized in that during the stroke of carriage (3) there occurs a variation of the speed of belts (11).
A device as claimed in any of the preceding claims, characterized in that at the time of the separation of the scale the speed of belts (11) is reduced relative to the speed of belts (12 and 17).
