摘要:
A method for supplying plate elements to a machine for processing the plate elements, from an initial pile of elements, the method includes: pushing a first batch of plate elements, from the top of the pile, downstream until the first batch comes at a storage capable of storing the first pushed batch, and simultaneously, displacing the storage downstream over a distance corresponding to the length of the first batch to separate the first batch from the pile; and thereafter transferring the elements of the first batch one after the other to the machine.

There is described a method for processing bundles (5) of securities, in particular banknote bundles, during production thereof, the method comprising the steps of (a) processing stacks of sheets (SS), each carrying an array of multiple security prints arranged in a matrix of rows and columns, into successive sets (2) of consecutive bundles (5) of securities arranged side-by-side, (b) forming at least one intermediate pile (8; 8*) of consecutive bundles (5) by placing the consecutive bundles (5) of a set (2) one on top of the other, and (c) successively ejecting bundles (5) one-by-one from a bottom of the said at least one intermediate pile (8; 8*) and conveying each ejected bundle (5) with a determined spacing from a preceding and/or following ejected bundle (5). There is also described a bundle processing system to carry out the above method.

A transfer system for transferring a stack (101) of flat elements to a processing device includes a delivery ramp (103) with a receiving surface (104) for receiving the stack (101), a first comb structure (121) having at least one first supporting platform (123) on which at least an edge portion (115) of the stack (101) is supportable, wherein the first comb structure (121) is mounted to the delivery ramp (103), and a second comb structure (122) having at least two second supporting platforms (124) on which at least the edge portion (115) of the stack (101) is supportable, wherein the second comb structure (122) is configured for supplying the stack (101) to the processing device. The first supporting platform (123) and the second supporting platforms (124) are arranged along a first direction (109), one after another, in an interleaved manner such that the edge portion (115) is supportable on the first supporting platform (123) and the second supporting platforms (124). The first comb structure (121) and the second comb structure (122) are movable along a lifting direction (110) with respect to each other such that the edge portion (115) of the stack (101) is supportable selectively by the first supporting platform (123) or by the second supporting platforms (124), wherein the two second supporting platforms (124) are spaced along the first direction (109) such that the first supporting platform (123) is movable along the lifting direction (110) through a space between the two second supporting platforms (124).

Method and apparatus for prefeeding corrugated boards to a box finishing machine wherein a stack of rectangular boards are moved to a first conveyor with the long dimension of the boards extending transverse to the direction of movement of said first conveyor. The stack is then rotated to place the long dimension of the boards in alignment with the direction of movement of said first conveyor, and then moving the rotated stack to a second conveyor for feeding to a box finishing machine with the long dimension of the boards in alignment with the direction or path of movement of the boards through the box finishing machine. The stack is transferred to the first conveyor from an elevator which contains a supply of boards larger than the stack. Three different types of apparatus are disclosed for rotating the stack. One is a plurality of conveyor belts whose speeds may be varied to rotate the boards. Another is a turntable with a set of belt conveyors and a set of rollers. The third is a vertical chute whose guides rotate the boards as they descend through the chute.

A squaring and aligning assembly for the transfer frame of a corrugated sheet stacking and feeding apparatus is mounted within a transverse guide member in the form of an elongated channel. Separate squaring shoes at each side of the machine are selectively moved along the channel. They can be connected in centered positions along opposite flights of a powered chain to center a block of sheets relative to the machine. One can be connected to a chain flight in an off-center position to align the block of sheets in an off-centered aligned condition. Either shoe can be clamped to the channel for edge alignment in response to movement of the remaining shoe.

A corrugated sheet stacking and feeding apparatus is provided in which stacks of sheets are fed to the unstacking apparatus and are raised to an elevated position in which blocks are progressively removed from the top of the stack and pushed and fed onto an inverting carriage that receives the blocks and pivots the blocks vertically upward and then to an inverted position over a feed conveyor. While the block of sheets are raised to a vertical orientation, alignment elements move inward along the lateral sides to align the lateral edges of the sheets with respect to each other and to laterally shift the block to align the block with a central feed axis. The block then is lowered onto the feed conveyor and moved forward through a shingling gate to feed the sheets progressively in a shingled fashion to a discharge end of the conveyor.

A method of separating at least one sheet metal element from the lower end of a stack (4) of apertured sheet metal elements, the separation comprising utilizing in motion phases two tool parts (1, 2), the method comprising:(a) a first motion phase, wherein sheet metal elements become sufficiently shifted by translation and/or rotation relative to one another at a separation plane of the stack that those elements do not inter-engage at their apertures; and(b) a second motion phase, wherein below the plane, the shifted sheet metal element(s) is(are) lowered from the plane, this lowering being such that in a third motion phase, those lowered element(s) will become completely separated from the rest of the stack by being further shifted sideways; wherein in the method:(i) sheet metal elements to be separated are gravitationally lowerable; and(ii) sheet metal element(s) remaining in the stack during the second motion phase is(are) held by support provided at the bottom surface of the remaining stack.

The present disclosure includes an apparatus for feeding a stack of sheet stock in blocks. The apparatus includes a backstop, a block pusher plate, and at least one sensor for determining a height differential between the stack at generally near a lead edge of the stack and the stack at generally near a trail edge of the stack. The apparatus automatically adjusts for warp in the sheet stock. The present disclosure further includes a method comprising obtaining a first measurement at generally near a lead edge side of the stack, obtaining a second measurement at generally near a trail edge side of the stack, comparing the first and second measurements, and pushing the portion of sheet stock from the stack with a block pusher plate when the second measurement is within a predetermined tolerance of the first measurement.

The feeding method concerns the transfer of panels (2) from the top of a vertical stack (17) to a loading table (4) on a panel saw machine. The panels (2) are pushed by mobile horizontal pushers (7) from the stack (17) until they arrive at an infeed device (8) which conveys the panels (2) to the loading table (4). The pushers (7) and the vertical stack (17) perform relative movements controlled by control means (70), so as to allow the pushers (7) to transfer from the stack (17) one or more panels (2), depending on the extent (h) of the relative translation. The infeed device (8) comprises at least two pairs of rollers, each pair comprising a motor-driven roller and an idler roller. The center distance of a pair of rollers may be adjusted by adjusting the idler roller.
