An apparatus for supplying a stack of carton blanks from a pallet to the magazine of a carton-packing machine in which the carton blanks are arranged vertically adjacent to each other, in particular for the tobacco industry, comprises an unloading carriage which is pivotable about a horizontal axis from a substantially vertical position into a substantially horizontal position and has an unloading fork which is movable along the unloading carriage and the prongs of which in the vertical position of the unloading carriage and thus in the horizontal position of the unloading fork can be inserted beneath the stack into the gaps between the boards at the upper side of the pallet. A drive displaces the unloading carriage and thus the prongs in the direction of the gaps between the boards at the upper side of the pallet; a retaining device provided on the unloading carriage holds, in the substantially horizontal position of said unloading carriage, the stack of carton blanks in the vertical position; a conveyor for the transfer of the individual blanks from the unloading carriage to the magazine is integrated into the unloading carriage.

A device for lifting at least one material stack from a support, in particular a stack of blanks from an intermediate support or bottom support in the tobacco industry, comprises the following features: a gripper is guided freely movable in all directions by an industrial robot; the gripper comprises at least one clamping element which is displaceable in the vertical direction and adapted to be placed on the or each stack, at least one elastically deformable finger insertable between the stack and the intermediate or bottom support as well as sensors for detecting the distance between the gripper and the stack; a control circuit including at least one logic unit evaluates and processes the output signals of the sensors and controls the movement of the gripper from a predetermined starting position into the lifting position, the clamping of a stack between a finger and a clamping element, and the subsequent lifting and the carrying away of the or each stack.

Device for lifting at least one material stack

Device for continuous feeding of a ribbon shaped material to a processing machine, complete with a swingable bobbin-carrier, mounted on bearings to a base frame, with at least 2 spindles for the reception of each bobbin.
