摘要:
A labelling machine for labelling a stack of elements is intended for the automated placement of a label located between elements forming part of the stack, and includes a support structure; printing means configured for printing a label to be placed on a stack of elements; a head supported on the support structure, the head being provided with printing means, the head being movable and adjustable at least in height through guiding means and motorized means; and separation means intended for separating two elements superimposed on one another forming part of the stack, such that they vertically separate an element to be handled, generating a free space between the two elements intended for the arrangement of the label.

A method and apparatus for automated aerating and handling a sub stack of a stack of rectangular paper sheets where the sub stack is gripped near or at opposed corners of a common edge of the sub stack by means of two robotic grippers (A, B) having two opposed gripping fingers (A1, A2, B1, B2), lifting and rotating the corners in mutually opposite first directions such that the work stack achieves an upwards concave form, gripping the corners by the robotic grippers (A, B), and rotating the grippers in second directions opposite to the first directions such that the upper sheet of the sub stack has a curvature smaller than the bottom sheet of the sub stack, preferably a substantially plane form.

A ream is selected and separated from a stack of sheets by a separating member which is inserted inside the stack at an insertion region defined by images acquired by an optical device, such as a television camera, moved vertically to scan a given scanning region of the stack. The optical device and the separating member are oriented with respect to each other such that the insertion region lies in the scanning region.

A method of picking up stacks (3) of blanks by means of a gripping device (1) having a gripper (13, 14, 15) hinged to a frame (11) and equipped with a first gripping member (15) having a free end (P); and actuating means (30, 41; 24, 25) for opening and closing the gripper (13, 14, 15); the method providing for pressing the free end (P) on a support (F) on which a stack (3) for pickup rests, and feeding the free end (P) along the support (F) and beneath the stack (3) while pressing the free end (P) against the support (F).

A reloading device for stacks of sheets of paper or plastic has at least one receptacle for receiving a stack and at least one support onto which the stack is placed. At least one peeling device is arranged at a bottom end of the at least one receptacle, wherein the peeling device is configured to move transversely to the stack and, when moving transversely to the stack, to peel in a peeling step at least one sheet from a bottom end of the stack. The peeling device is preferably a peeling blade.

A system for transferring flat bodies, wherein an actuating unit transfers the flat bodies in a given direction from a pickup station to an unloading station; a carriage being movable horizontally between the pickup and unloading stations; a pickup member being supported by the first carriage to load blocks of stacked flat bodies at the pickup station; the pickup member having a stop member crosswise to the given direction, and acting as a locator for a block in the given direction; and the actuating unit having a retaining device facing the stop member to limit displacement of the flat bodies on the pickup member during transfer between the pickup and unloading stations.
摘要:
An apparatus and method of preparing bundles for binding, where the method is carried out at a high processing frequency and the device is of a compact construction, where bundles of sheets are raised from the upper end of a supply stack of a punching device in a continuous manner by means of an engagement tool and the respective bundle is displaced by a pusher, with the result that its opposite border region projects into a punching device and is processed there. Lifting edges of two rotating disc segments then engage beneath the opposite border of the bundle, the border being retained by the pusher, and raise the border until the region adjoining it is clamped between partially cylindrical clamping surfaces of the disc segments, the clamping surfaces adjoining the lifting edge, and a likewise rotating clamping roller, and the bundle is fed, counter to the displacement direction, to a transportation device, where the bundles are clamped between two pairs of transporting belts and are transported to an end stack. The bundles are turned at the same time they are transported. The bundles follow one after the other at a distance which is smaller than the width of a bundle, with the result that they overlap in an imbricated manner.

The device (1) for picking up, moving and depositing a pile (9) of carton blanks comprises an element (3) suitable for moving according to three Cartesian axes, and to cause to rotate on itself, according to a vertical axis (7), a clamping element (2) which comprises three movable plates (11-13) cooperating with a pressing element (14).
摘要:
Stacks which are about to be subdivided by a sword-like tool at a dividing station are monitored by a spring-biased mechanical sensor which causes the generation of signals serving to change the position of the stack at the dividing station with reference to the tool and/or vice versa if the monitored height deviates from an anticipated height so that the tool divides the stack into piles of desired height. The sensor monitors the stacks ahead of the dividing station.
摘要:
A device for removing a desired number of plates from a stack of plates such as a stack of punched plates for making stators for electric motors. The stack is held in compression and a knife member is brought into contact with the side of a certain plate in the stack thus locating a desired number of plates between the knife and one end of the stack. Clamping means are provided adjacent the knife member to engage the stack such that when the compressive force holding the entire stack is removed, the portion of the stack between the clamping means and the one stack end is held in compression by the clamping means. In this manner, the desired number of plates are held stationary relative to the knife member and thus do not move relative to the knife member when the compressive force is removed. After separation of the other portion of the stack, the knife member and clamping means are disengaged from the portion of the stack containing the desired number of plates and a stack containing the desired number of plates is removed from the device.
