Definitions

• the invention relates to a device and a method for aligning sheets arranged one above the other in a layer according to the preamble of claims 1, 8 or 10.
• Devices are used, for example, but by no means exclusively, to align printed sheets one above the other with sufficient accuracy on at least one edge, so that the stack can then be trimmed at the edges.
• some printed products for example value notes provided with registration numbers, it is necessary after the sheets have been printed that the sequence of the sheets is maintained in the layer forming a stack.
• DE-PS 12 32 986 discloses a stacking device for folded sheet layers.
• the scaled sheet layers are guided and turned around a cylinder by means of a belt transport system. Then the sheet layers are aligned with the stops and stacked.
• EP 0 173 959 A1 shows a sheet processing machine to which sheets are fed from an underside of a first stack. After processing, the unscaled sheets are transported to a tray by means of a belt system and placed on top of a second stack with a suction conveyor.
• a device which is designed in the manner of a vibrating table.
• a support table is provided, lateral stops being arranged on at least two adjacent sides of the support table, which stops can come to rest on the side edges of the sheets.
• the sheet is placed on the support table and this is then inclined so far in the direction of the two stops that the side edges of the sheet come to bear on the stops due to the force of gravity.
• the vibrating table is then vibrated in order to loosen up the position of the sheets and to enable an alignment movement of the individual sheets relative to one another.
• the invention has for its object to provide a device and a method for aligning sheets arranged one above the other in a layer.
• a sheet feeder is provided in the device, which takes the sheets deposited on the support plate individually and conveys them further to form a shingled stream of shingled material.
• shingled stream of shingles the leading edge of each arch lies below the immediately preceding arch.
• a turning device is provided in the device, with which the stream of flakes is turned. The result of the reversal of the shingled stream is that each sheet is freely accessible in the area of its leading edge.
• a conveyor is then behind the turning device for the actual alignment of the individual sheets provided with which the sheets are conveyed individually to the leading edge stop of the support table.
• the desired alignment of the sheets is achieved and at the same time a new layer of sheets is formed, all of which are in contact with the leading edge stop. Since the sheets rest on the newly formed layer during the alignment movement at the leading edge stop, the alignment movement is not impeded by the weight of the other sheets. At the same time, however, the order of the sheets is preserved, unlike, for example, when stacking. After all of the sheets in the original position had run through completely, a new layer of sheets with an aligned leading edge was then formed on the support table, the original top sheet being in the new position at the bottom.
• Figure 1 shows a device for aligning sheets in a perspective view from above.
• FIG. 2 shows the device according to FIG. 1 in an enlarged detail in a perspective view from above;
• FIG. 3 shows a turning device for use in a device according to FIG. 1 in a perspective view from below.
• a known sheet feeder 02 can be used to form a device 01.
• the sheet feeder 02 there is a support plate, shown concealed in FIG. 1, on which a layer of sheets 04 arranged one above the other, for example sheets printed with value notes and registration numbers, can be placed.
• a movable suction unit 03 By using a movable suction unit 03, the sheets 04 are removed individually from the position in a known manner and conveyed further in the direction of a turning device 06 to form a shingled stream of shingled material, in which the sheets 04 with their leading edge lie below the previous sheet 04.
• a side drawing mark 07 is provided, on which the right side edge of the individual sheets 04 of the shingled stream are laterally aligned.
• the conveying speed of the suction belts 08 in the sheet feeder 02 is higher than the conveying speed of the suction belts 09 in the turning device 06, so that, as a result, the conveying speed of the scale flow after aligning the sheets 04 on the side drawing mark 07 is reduced. As a result, the overlap between the individual sheets 04 in the shingled stream is increased and the shingled stream is thus conveyed more slowly, so that the material flow with the sheets 04 already aligned laterally becomes quieter.
• Control commands for the device 01 can be entered on a control panel 11 and various operating states can be displayed.
• the sheets 04 are drawn in between the suction belts 09 and circumferential guide belts 12 and turned through 150 ° - 210 ° and in the direction of a roller 13, e.g. B. a suction roller 13 further promoted.
• the suction roller 13 rotates in the direction of the movement arrow 14, so that the sheets 04 of the shingled stream that is shingled at the inlet are turned in such a way that the sheets 04 are freely accessible at the outlet of the turning device 06 in the area of their front edge, whereas the rear edge of each sheet 04 is below the subsequent arc 04 in the stream of shingles.
• a support table 16 is arranged behind the outlet of the turning device 06, at the rear end of which a front edge stop shown in FIG. 2 is provided.
• a suction body unit 17 serving as a conveyor 17 two rotationally driven suction body 18, z. B. a suction roller 18, the individual sheets 04 of the shingled stream can be sucked one after the other in the region of their front edge and conveyed against the front edge stop shown in a concealed manner.
• Continuous operation of the device 01 forms on the support table 16 a new layer of sheets 04 arranged one above the other, the front edge and the side edge of which are each aligned.
• the height of the new layer can be measured with a sensor (not shown) and the absorbent unit 17 can be adjusted vertically depending on this measured value.
• the suction rolls 18 are always at the level of the top of the new layer with their circumference and thus do not press on the top sheet 04 to be aligned in each case.
• the device 01 can be operated as follows, for example:
• the device 01 is switched off for a certain time, so that the sheet travel is interrupted.
• the sheets 04 combined in a shingled stream are then conveyed by the turning device 06 to the support table 16 and stacked there to form a new layer.
• the respective position is conveyed further from the support table 16 in the direction of a downstream device (not shown), which serves, for example, to trim the edges of the sheets 04.
• the leading end of the sheet removed from the first stack points in the direction of transport, i. H. the leading end of the sheet is also leading in relation to the direction of transport for the discard pile.
• a camera system 21 can be provided in the device 01, with which the registration numbers of the individual sheets 04 can be observed.
• the turning device 06 is shown with the rotating guide bands 12 and the suction roller 13 in a perspective view from below. It can be seen that the guide belts 12 are guided along the suction boxes 22 at the outlet of the turning device 06 and thus function in the manner of suction belts 12 at the outlet of the turning device 06. This ensures that the sheet 04 is sucked in at the outlet of the turning device 06 and its position is secured in this way.
