Definitions

  • the invention relates to a device for stacking sheets, especially sheets of paper or cardboard transported by a stream feeder, onto pallets, with a stacking platform that can be raised or lowered on which the stacks are formed, and with at least one separating plate that guides the longitudinal edge of a sheet during the stacking, that is suspended on a holder attached to the machine frame and with a vibrator as a shaking element.
  • German patent application DE 29 42 855 A1 discloses a stacking device for a printing machine that has vibrating means, each with a linear vibrator, arranged at the vertical sides of the paper stack. Each vibrator is elastically suspended by means of a holding plate, a rubber block and a holding brace on a stationary frame part of the stacking device. Its armature shaft is connected to the vibrating plate.
  • German patent DE 42 21 660 C2 Another stacking device with vibrating means is described in German patent DE 42 21 660 C2.
  • a stop plate consisting of two parts is vibrated, whose front part is attached to the back part via elastic rubber damping elements.
  • the vibrating means is attached to the front part as well as to the back part of the stop plate.
  • the invention is based on the objective of improving the vibrating effect of the separating plates in a device of the generic type.
  • This objective is achieved in that, on the holder attached to the machine frame, there is a holding plate attached via rubber elements so as to be vibration-uncoupled and on which the separating plate and a vibrator are rigidly suspended.
  • This construction has the advantage that, during the vibration, the vibrator itself can only rest on the stack so that the entire vibration energy is transmitted to the stack. This greatly increases the effect of the vibrator.
  • Another advantage is that the vibrator does not impart vibrations to any other parts of the stacking device. Thus, the rest of the suspension of the separating plate is less stressed.
  • the separating plate is detachably attached to the holding plate. Consequently, it can be replaced without disassembling the vibrator.
  • the embodiment of the holder according to Claim 3 as a holding plate that can be raised and lowered makes it possible to raise the separating plate with the vibrator into an inactive position above the stack when it is not needed.
  • an ejection roll and a separating shoe are attached to the holding plate so that all of the stack-forming elements that act on a longitudinal edge of the sheet can be raised and lowered with one single shared lifting drive.
  • FIG. 1 is a schematic representation of the side view of a stacking device.
  • FIG. 2 is an enlarged representation of the side view of the stack-forming elements acting on the longitudinal edges of the sheet.
  • FIG. 3 is a view of the stack-forming elements opposite from the sheet-travel direction.
  • FIG. 4 is a schematic view of the suspension of a separating plate with the appertaining vibrator.
  • the stacking device shown in the figures serves to stack sheets 1 of paper or cardboard that are continuously fed by a stream feeder and that were produced with a crosscutting machine.
  • the sheets 1 are fed to the stacking station by a feed mechanism 2 that is configured as a conveyor belt and that is arranged at a fixed vertical position above the ground at a height above the maximum stack height.
  • the stacks 3 are formed on pallets 4 that lie on a stacking platform 5 .
  • the stacking platform 5 is suspended in the frame of the stacking device so that it can be raised up to the area of the feeding level of the sheets 1 and lowered to the floor area.
  • the frame of the device comprises two inlet-side posts 6 and two outlet-side posts 7 that are arranged outside of the working width on the two longitudinal sides of the machine and that are connected to each other at their upper ends by longitudinal beams 8 and transverse beams.
  • the posts 6 , 7 define the limits of the stacking station.
  • the crosscutting machine additionally cuts the web of paper or cardboard—from which the sheets 1 are made—into individual webs by making an appropriate number of longitudinal cuts before the crosscutting operation.
  • the device comprises a stop plate 9 extending crosswise over the working width of the device, whereby the leading edges of the sheets are aligned against said stop.
  • the stop plate 9 In order to adjust the position of the stop plate 9 in the longitudinal direction for different paper lengths, it is suspended so as to be longitudinally slidable at the rear of the stacking station.
  • ejection rolls 10 Downstream from the feed mechanism 2 , crosswise over the working width, there are ejection rolls 10 arranged at a distance from each other, by means of which the sheets 1 are transferred to the stacking station. In the sheet-travel direction, immediately downstream from the ejection rolls 10 , there are separating shoes 11 by means of which the longitudinal edges of two adjacent sheets 1 are bent upwards. The curvature of a sheet 1 along its longitudinal edges leads to so-called cupping, which stabilizes the sheet 1 and, at the same time, brings about a reliable separation of two adjacent sheets 1 .
  • each separating shoe 11 Downstream from each separating shoe 11 , there is a separating plate 12 that extends upright and in the sheet-travel direction.
  • the separating plates 12 have the function of laterally guiding and aligning the sheets 1 in order to place them with precisely aligned edges on the stack. Therefore, said separating plates are arranged in the stacking station between two stacks 3 and on the two outer longitudinal edges of the outer stack 3 .
  • the separating plates 12 are each suspended on a holder attached to the machine frame and connected to a pneumatic or electric motor vibrator 13 that serves as the shaking drive, by means of which they are vibrated at a frequency of several Hertz.
  • the suspension of a separating plate 12 with a vibrator 13 is shown in greater detail in FIGS. 2 and 3 and is depicted schematically in FIG. 4 :
  • a separating plate 12 is suspended together with the ejection rolls 10 and the separating shoe 11 on a holding plate 14 that serves as a holder and that is attached to the end of two guide rails 15 .
  • the guide rails 15 are attached to a carriage 16 that is mounted on a crossbar so as to slide crosswise.
  • a piston-cylinder unit 17 likewise attached to the carriage 16 and to the holding plate 14 makes it possible to raise the holding plate 14 with the elements attached thereto out of their working position into an inactive position above the stack 3 .
  • the shared suspension of the ejection roll 10 , of the separating plate 12 and of the separating shoes 11 has the advantage that these elements can be adjusted crosswise by one single shared traversing drive and they can be raised and lowered by a shared lifting drive (piston-cylinder unit 17 ).
  • the holding plate 14 there is a second holding plate 18 that is arranged in the front in FIG. 2 and to the left of the holding plate 14 in FIG. 3 .
  • the second holding plate 18 is attached to the holding plate 14 exclusively by means of rubber elements 19 that have a damping effect so that the two holding plates 14 , 18 are vibration-uncoupled from each other.
  • rubber elements 19 preference is given to the use of so-called metal-rubber elements that are rubber-elastic and that have a damping effect.
  • the separating plate 12 and the vibrator 13 are attached so as to be suspended rigidly.
  • the vibrator 13 Due to the vibration-uncoupled attachment of the second holding plate 18 to the first holding plate 14 that serves as a holder, the vibrator 13 cannot cause the first holding plate 14 to vibrate.
  • the ejection rolls 10 are attached via a bearing bracket 20 to this non-vibrating holding plate 14 .
  • the separating shoe 11 is connected to the vibrating holding plate 18 , so that it is made to vibrate together with the separating plate 12 .
  • the vibration of the separating shoes 11 causes the sheets 1 to slide more easily downwards onto the stack 3 .
