Abstract:
A sheet stacking device (10) for forming a stack of subsequent sheets, wherein in operation a sheet follows a transport path from a sheet supply to a receiving plane on which the stack of subsequent sheets is formed, the sheet stacking device comprising: a rotatably arranged flipping element (22, 23), comprising a slot (26, 27) at its circumferential edge for accepting at least a portion of a sheet to be stacked, configured such that, in a first rotation zone, the rotatably arranged flipping element is able to accept the sheet from the sheet supply into the slot and, in a second rotation zone, the sheet is conveyed out of the slot onto the top of the stack of subsequent sheets on the receiving plane; a closed-loop shaped friction element (28, 29) moveably arranged on the rotatably arranged flipping element, such that the closed-loop shaped friction element is controllable to move into one of a first radial position and a second radial position, such that in the first radial position, the closed-loop shaped friction element does not apply a frictional force to a sheet in the transport path and such that in the second radial position, the closed-loop shaped friction element does apply a frictional force to a sheet in the transport path.
Abstract:
A diverter device (10) for deflecting sanitary articles (A) from a flow of articles being fed along a path includes: • - an arch-shaped deflector element (12) that may be set straddling the aforesaid path of feed of the articles (A); • - a supporting structure (14) that supports the deflector element (12) with capacity for moving between an inactive position, in which the deflector element (12) does not interfere with said articles being fed (A), and an active position, in which the deflector element (12) interferes with the articles to deflect them from the flow; and • - an actuator mechanism (20, 24, 26, 34, 36) for producing movement of the deflector element (12) in a controlled way between the active position and the inactive position.
Abstract:
Die Erfindung betrifft ein Verfahren zur Regelung einer Rotationsgeschwindigkeit und/oder einer Drehwinkellage eines ersten lagegeregelten Antriebsmotors einer ersten Vorrichtung (v*) eines Falzapparats (01), wobei mittels eines Sensors (21) eine Lage einer Signatur (22) an einer Erfassungsposition erfasst wird und wobei ein erstes Signal von diesem Sensor an eine dem Falzapparat zugeordnete Maschinensteuerung gesendet wird und wobei zumindest eine, die Signatur zwischen der Erfassungsposition und der ersten Vorrichtung transportierende zweite Vorrichtung mittels eines zweiten lagegeregelten Antriebsmotors angetrieben wird und wobei der erste und der zweite lagegeregelte Antriebsmotor mit der Maschinensteuerung verbunden sind und wobei eine Drehwinkellage des ersten Antriebsmotors charakterisierende Lagesignale und eine Drehwinkellage des zweiten Antriebsmotors charakterisierende Lagesignale jeweils an die Maschinensteuerung gesendet werden, wobei eines dieser Lagesignale ein zweites Signal darstellt, das eine Drehwinkellage der ersten Vorrichtung charakterisiert und wobei die Maschinensteuerung auf Grund des ersten Signals und des zweiten Signals die Rotationsgeschwindigkeit und/oder die Drehwinkellage des ersten Antriebsmotors der ersten Vorrichtung regelt.

Abstract:
Sheet stacking device and method of stacking sheets, wherein a first pressing member (40) engages with an edge (38) of a new sheet (21) to be deposited on top of a previously deposited sheet (21) on a sheet receiving plane (14) and presses down said edge (38), while a second pressing member (42) maintains a pressure onto an edge (38) of the previously deposited sheet (21); then, the second pressing member (42) engages with said edge (38) of said new sheet (21) and presses down said edge (38) onto the previously deposited sheet (21) on the receiving plane (14), while the first pressing member (40) maintains a pressure onto said edge (38) of the new sheet (21). Thus, the sheets (21) may always be pressed down on the edge (38) by at least one of the first and second pressing members (40; 42).
Abstract:
At least two sheet conveyors are provided in such a way that several of these conveyors can rotate around the common axis, essentially independent of one another, and thus one of these sheet conveyors is ready to accept or detect the next sheet, if another of these sheet conveyors is still occupied with the transport or the placement of a preceding sheet and that a sensor is coupled mechanically with several of these sheet conveyors.
Abstract:
At least two coaxially rotatable sheet conveyors, operating together with one another, are provided, of which the first sheet conveyor, with a jacket surface serving as placement for the sheet, specifies essentially a curvature path for the sheet to be conveyed, and the second sheet conveyor has at least one gripping element to grip the accepted front edge of the sheet, in such a way that the front edge of the sheet can be gripped and conveyed between the gripping element and the jacket sheet.
Abstract:
The invention relates to a device for the transversal displacement of folded products, each nth folded product being laterally offset by a value (x) in the bucket wheel (01), before being distributed in the production direction (D). This allows, for example, every second subsequent folded product to be separated from the production stream.
Abstract:
An inspection and/or processing apparatus for sheets such as banknotes includes a stacker wheel arrangement in which, rather than continuously rotating the stacker wheel (20) and decelerating or accelerating the wheel to adjust the wheel speed in order to cause the grooves (22) to align with the entrance chute at the same time that sheets arrive at the wheel, the stacker wheel is rotated only between sheet arrivals, and only for the purpose of indexing the stacker wheel to a new position at which a sheet can enter the stacker wheel without jamming. Indexing of the stacker wheel follows a predetermined profile, and the stacker wheel held stationary at each predetermined aligned position until a respective individual sheet has entered the stacker wheel.
