Abstract:
In a sheet processing method for sheets of paper or cardboard, a sheet for processing is, in the processing station, firstly brought to a standstill and then set down, whereas the processed sheet is, in the output station, set down from a moving state. A punching or stamping machine has an input station, a processing station and an output station arranged one behind the other in a sheet transport path, and a sheet gripping device which is designed to set down a sheet for processing in the processing station when the sheet gripping device has come to a standstill in a second reversal position, and to set down a processed sheet in the output station as the sheet gripping device approaches the second reversal position.
Abstract:
In an apparatus for overturning sheets and/or panels, a bearing structure carries a loading plane, and roto-translation means vertically translate the loading plane and rotate the same with respect to an axis. A grab device carried by the loading plane serves to transfer a sheet and/or panel from a supply station, when stopped upstream of the apparatus, on an operating surface. A command and control unit in alternatively activating and de-activating the roto-translation means, the stabilization and transfer and the grab device, defines for the loading plane a collection position, an overturning position and an unloading position of a sheet and/or panel to be overturned by the supply station placed upstream of the apparatus, over an unloading station downstream of the apparatus.
Abstract:
A system may include a robotic arm and a Bernoulli cup assembly powered by a vacuum source and coupled to the robotic arm. The Bernoulli cup assembly may lift a document, and the robotic arm may move the Bernoulli cup assembly with the lifted document to a document scanner for imaging the document. The system may further include an input bin, a base supported by a platform and disposed over an imaging surface of the document scanner, and an output bin. A method may include lifting a document from an input bin via suction pressure using a Bernoulli cup assembly, robotically moving the Bernoulli cup assembly with the lifted document to a document scanner, and scanning the document. The method may further include robotically moving the Bernoulli cup assembly with the lifted document away from the document scanner, and de-activating the suction pressure to release the document.
Abstract:
An apparatus is provided for receiving and positioning veneers fed by a conveyor belt. The apparatus includes grippers controlled to be independently movable, for gripping the veneers, and detection means for detecting the location and/or position of the veneers on a conveyor belt. At least one gripper is disposed on both sides of the feeding direction center line of the veneer. The grippers are arranged to reciprocate at least in the feeding direction of the veneers, to grip each successive veneer on its leading edge side, and to align the leading edge side of the veneer to correspond to the position of the veneer in the veneer assembly, in response to information provided by the detection means.

Abstract:
A device for positioning a plate element (7a, 7b, 7c) in an infeed station (2) of a machine for treating the element (1), fitted with a conveyor (8, 9), gripping the element (7a, 7b, 7c) which is found in a predetermined intermediate position, and carrying the element (7a, 7b, 7c) in a rated running into successive processing stations (3, 4, 6). The device includes a holding device (18) for temporarily holding the element (7a, 7b, 7c), the holding device moving longitudinally alternatively (A) from an upstream position to a downstream position, and vice-versa, to pick up the element (7a, 7b, 7c) in a rear position and bring it to the intermediate position, and to return empty. A motor (23) moves the holding device (18) longitudinally, from the upstream position to the downstream position, and vice-versa, as a function of the rated running. A detector (27) detects a rear longitudinal position in which the element (7a, 7b, 7c) is found, and emits a position signal. The motor (23) is able to move (A, Aa, Ab, Ac) the holding device (18) from the upstream position to various downstream positions, as a function of the signal emitted by the detection device (27), so as to bring the element (7a, 7b, 7c) from the rear position to the intermediate position.

A conveyor system for transporting a printing plate in a platemaking system includes: a carriage riding on a track and one or more low friction substantially horizontal planar support surfaces provided as a high wear laminate, positioned above the carriage and the track, for supporting the printing plate on the non-emulsion side without the use of rollers, belts, bearings or air cushioning. The carriage includes one or more engagement mechanisms for engaging a bottom, non-emulsion side of the printing plate, and the track includes an air cylinder. The engagement mechanisms can be, for example, suctions cups which engage the plate by a vacuum, suction cups which engage the plate by pressure and adhesion, other adhesive devices, or a mechanical gripper for gripping the plate. The track or linear actuating system is preferably an air cylinder. Alternatively the linear actuating system could include a belt and pulleys, a chain and gears, or a threaded lead screw.
