A device for feeding sheet products into a thick sheet feeding machine including an insertion gantry, a feed carriage sliding on rails. The device includes an insertion head configured as a gantry. The insertion head includes a crosspiece and support legs positioned on the rails and a system of suction cups located in the crosspiece through a forward movement mechanism allowing the system to move. The device includes an insertion module moving vertically on guides of the insertion gantry, a base for placing the sheets, and an alignment control device for aligning the sheets with respect to the insertion module. The sheets are suctioned by the suction cups, which are moved by the forward movement mechanism in the direction of the insertion gantry.

A device is provided for feeding sheets to a sheet-processing machine having at least one processing mechanism. A feeder head is provided for cyclically separating the sheets from a pile of such sheets and has transporting suckers for transporting the sheets to a belt table. The belt table has at least one revolving transport belt which is guided over at least two feed rollers. A first drive is assigned to at least one feed roller and a sheet flap, which is connected to a pivotally mounted shaft, is provided between the transporting suckers and the at least one transport belt. A second drive is assigned to the shaft, for pivoting that shaft. A sheet arrival sensor, which is arranged between the belt table and the processing mechanism, generates first signals representing the arrival of the sheets for a sequence of sheets. A clock generator generates second signals representing the angular position of the at least one processing mechanism, and has a controller, which controls the first drive as a function of the second signals and which controls the second drive as a function of the first and second signals.

A medium feeding device includes a storage unit that stores media in a form of a sheet, a delivery unit that is disposed downstream in a medium delivery direction relative to the media stored in the storage unit and that delivers the media individually, a transfer unit that is disposed above the storage unit and that adheres by suction to each of the media stored in the storage unit and transfers the media to the delivery unit, and a fluffing unit that is disposed beside the media stored in the storage unit in a direction intersecting the medium delivery direction. The fluffing unit fluffs an upper-side region of the media in a state of being separated, by blowing air toward a side of the media during a feeding job of the media and during a post-feeding period that is a predetermined period after completion of the feeding job. The medium feeding device further includes a suppression unit that suppresses movement of the media toward the delivery unit side during air blowing performed by the fluffing unit in the post-feeding period.

A method and apparatus are disclosed for removing one item of media at a time from an item of media container. The apparatus includes a movable element locatable in an abutting relationship with an elected item of media in a media container and disposed to vibrating against the elected item of media to permit the elected item of media to be subsequently be removed alone from the container.

Disclosed is a film feeding apparatus including a turntable including a driving member and a rotation bar having a central part shaft-coupled to a rotating shaft of the driving member to be driven to rotate around the rotating shaft and driven to rotate to repeatedly perform an operation in which the rotation bar rotates by a predetermined reference angle through the driving member and is then stopped for a predetermined reference time, a film tray that is installed in a predetermined first operation region to position one of opposite ends of the rotation bar on the film tray in a state in which the rotation bar is stopped for the reference time and on which a plurality of films are located in multiple layers, gripping units coupled to the opposite ends of the rotation bar, respectively, to transfer the films along a predetermined circular trajectory around the rotating shaft by the rotation bar and provided to grip the films, and a film ejection unit that is installed in a predetermined second operation region to position a remaining end opposite to the one end of the opposite ends of the rotation bar in the film ejection unit in the state in which the rotation bar is stopped for the reference time and provided to eject the films to an outside, wherein, in the state in which the rotation bar is stopped for the reference time, a griping unit positioned in the first operation region among the gripping units grips a film from the film tray, and a gripping unit positioned in the second operation region among the gripping units releases a film that is pre-gripped from the film tray and transfers the film to the film ejection unit.

The invention relates to a system for sorting veneer sheets. The system comprises: an assembly section; a reject section; a feeding section arranged between the assembly section and the reject section; at least one detection device configured to scan a top surface of a topmost veneer sheet of a stack of veneer sheets to provide a plurality of successive scan lines images; at least two parallel transfer devices; and a control system. The control system is configured to provide a surface scan image from the plurality of successive scan lines images, determine one or more properties of the veneer sheet based on the surface scan image, and to control the at least two transfer devices to: move from an avoidance position to a pick-up position determined based on the surface scan image; pick up the topmost veneer sheet of the stack of veneer sheets; and transfer the picked-up veneer sheet to the assembly section in response to detecting that each of the determined one or more properties of the veneer sheet meets a respective predetermined criterion, or otherwise transfer the picked-up veneer sheet to the reject section. The invention relates also to a method for sorting veneer sheets.
