Abstract:
1. A unit for preparing groups of products in layers for palletizing comprising: a motor-driven pick up and release element for controlling the pick up and the release of groups of products from a first surface to a second surface, said second surface being positioned adjacent the first surface, said second surface being movable forwards and backwards along a first axis X; a supporting frame for the motor-driven pick up and release element positioned over the two surfaces; said motor-driven pick up and release element having (a) a first drive unit for controlling movement of the pick up and release element forwards and backwards along a second axis Y perpendicular to said first axis X, and (b) a second drive unit for controlling movement of the pick up and release element up and down along a third axis Z perpendicular to said first axis X and perpendicular to said second axis Y, said pick up and release element being rotatable via a drive unit about said third axis Z, said pick up and release element being movable only (a) along said second axis Y, (b) along said third axis Z, and (c) rotatably about said third axis Z; said second surface comprising a respective drive unit for controlling the movement of the second surface along said first axis X; a microprocessor logic unit for controlling and programming the movement of the pick up and release element and of the second surface, said motor-driven pick up and release element and said second surface being movable for forming individual layers of two or more groups of products on the second surface according to the size of a pallet; an interface unit inserted between the logic unit, the pick up and release element and the second surface, controlled by the logic unit, and designed to allow the axes of motion of the pick up and release element and the axis of motion of the second surface to be coordinated in such a way as to form the layer according to the logic unit layer programming parameters.
