Abstract
A method for generating decks of sheet elements (18) comprises the steps of positioning a set of numerous sheet elements (18) onto a transport surface of a transport device (30) to partly overlap in transport direction (T). The set of overlapping sheet elements (18) is moved against a stop member (44). The stop member (44) is moved in the transport direction (T) with a lower velocity than a velocity of the transport surface. By maintaining displacement of sheet elements (18) which are not yet contacting stop member (44) all sheet elements are shifted towards stop member (44) to define a deck. The method is carried out by a corresponding device.
Claims11
A method for generating a deck of sheet elements, the method comprising:
- positioning a set of numerous sheet elements onto a transport surface of a transport device one after another such that the sheet elements are partly overlapping with adjacent sheet elements,
- wherein the transport device has a transport direction, and wherein a last sheet element of the set with respect to the transport direction is positioned to be a lowermost sheet element of the set, and other sheet elements being positioned so that a rear end of the sheet element lies onto a front end of the sheet element being adjacent in counter transport direction, so as to form a row of overlapping sheet elements,
- moving the row of overlapping sheet elements in the transport direction, and
- moving the overlapping sheet elements against a stop member, which is firstly contacted by an uppermost sheet element, until the lowermost sheet element is completely shifted underneath an adjacent sheet element, and wherein the stop member is moved in the transport direction with a lower velocity than a velocity of the transport surface.
A stacking device for generating a deck of sheet elements, the stacking device comprising:
- a first stacking station having a transport device comprising at least one endless belt defining an upper transport surface onto which sheet elements are deposited,
- the endless belt being able to move the sheet elements in a transport direction, and
- a stop member configured to move in the transport direction and being located adjacent to the transport surface, the stop member being arranged to be contacted by sheet elements deposited onto the transport surface, wherein the endless belt is configured to be driven faster than the stop member,
- wherein several transport sub devices for sheet elements are arranged parallel to each other, in particular wherein a stop member is arranged between adjacent transport sub devices, and
- wherein the stacking device comprises at least one slider movable crosswise to the transport direction to shift adjacent decks towards and above each other and to form a common deck.
A stacking device for generating a deck of sheet elements, the stacking device comprising:
- a first stacking station having a transport device comprising at least one endless belt defining an upper transport surface onto which sheet elements are deposited,
- the endless belt being able to move the sheet elements in a transport direction, and
- a stop member configured to move in the transport direction and being located adjacent to the transport surface, the stop member being arranged to be contacted by sheet elements deposited onto the transport surface, wherein the endless belt is configured to be driven faster than the stop member,
- wherein the stacking device comprises an inlet station arranged before a stacking station and a decelerating element for contacting the upper surfaces of sheet elements in order to arrange a row of overlapping sheet elements which is transported to the stacking station.
