Definitions

  • the invention relates to an accumulator for stacking sheets of paper, plastic, cardboard and the like according to the preamble of claim 1.
  • Accumulators combine sheets into stacks.
  • An example is bank statements that need to be stacked in a particular order.
  • the sheet provided with the address must be in the stack at the highest point so that it is visible in the envelope window during the subsequent insertion.
  • the sheets must be stacked or stacked.
  • the invention has for its object to form the generic accumulator so that easily with him in a simple manner a stacking and under stacking of the sheets is possible.
  • the sheets to be stacked are assigned via the feeding device to the recessed tray on which the stacking takes place.
  • the first fed sheet forms the bottom sheet in the stack.
  • the adjusting element is moved from the rest position to the operating position. Since the adjustment is located at the transition from the feeder to the lowered arranged tray, by the adjusting element, the feeder extended. This extension of the feeder is used to stack the supplied sheets with each other. This is possible by the fact that the rear end of the sheet or the stacking part already formed in the feed direction is raised by the adjustment so far that the subsequent sheet can get below the raised end of the sheet.
  • the accumulator is provided with a pocket, with which the stack formed from the sheets can be folded.
  • the sheets are transported so far in the tray until they rest against the stop of the bag. In this way, all the sheets in the stack are accurately positioned.
  • the folding operation takes place with a folding device connected downstream of the bag.
  • the accumulator has a support 1, on which the sheets 2 to be stacked are fed in a known manner.
  • the sheets 2 fall from the support 1 to a tray 3, on which they are transported with transport rollers 4, 5 in the direction of a pocket 6.
  • the transport rollers 4, 5 are advantageously suction rollers which are rotatable about mutually parallel horizontal axes 7, 8 in opposite directions to each other.
  • the suction rollers 4, 5 have in the lateral surface suction openings 9, 10, via which the sheets 3 to be stacked on the tray 3 are transported by application of negative pressure.
  • the tray 3 is interrupted in the region of the lower suction rollers 5, so that the suction force of the lower rollers 5 can act on the sheets 2.
  • the tray 3 is located at a distance from at least one guide plate 11 with respect to which the support 1 facing the end 12 is curved upward and at a distance from the support 1 is opposite.
  • the tray 3 and the guide plate 11 form a guide channel 27 for the sheets 2.
  • the free end 12 of the guide plate 11 extends, seen in the transport direction of the sheets 2, beyond the support 1 addition. Since it, with respect to the feeding direction of the sheets 2 on the support 1, convexly curved, the sheets are reliably guided in the transition from the support 1 to the tray 3 under the guide plate 11 in the guide channel 27.
  • the guide plate 11 is interrupted in the region of the upper transport rollers 5, so that the sheets 2 can be reliably detected.
  • the transport roller 13 Downstream of the two transport rollers 4, 5 is at least one upper transport roller 13, which is rotatably driven about an axis 14 lying parallel to the axis 7.
  • the jacket of the transport roller 13 is provided with a flat wall section 15. In the in Fig. 1 illustrated starting position, the transport roller 13 is positioned so that this flat wall portion 15 is parallel to the top of the stack formed from the sheets 2 on the tray 3.
  • the transport roller 13 is located in the region between the end of the guide plate 11 and the pocket 6, the upper boundary wall 16 is widened. This ensures that the sheets 2 can be reliably inserted into the pocket 6.
  • rollers 17, 18 which can be driven in opposite directions to one another and which contact one another and around one another parallel horizontal axes 19, 20 are rotatable.
  • the axis of rotation 19 of the roller 17 is located with the axis of rotation 14 of the transport roller 13 in a common vertical plane.
  • the axis of rotation 20 of the roller 18 is located in the region below the pocket 6, the lower wall 21 is tangentially brought to the mantle of the roller 18.
  • Fig. 2 shows, located in the area between the support 1 and the free end 12 of the guide plate 11 at least one adjusting element 22, which consists of a sunk rest position in the in Fig. 2 shown use position can be adjusted in the vertical direction.
  • the adjusting element 22 may be a roller, a ball and the like.
  • a plurality of rollers, balls and the like are provided as adjusting elements 22 transversely to the plane of the drawing. They are mounted in at least one carrier (not shown), which is mounted either in the vertical direction so as to be adjustable or pivotable in the vertical direction.
  • the adjusting element 22 is arranged so that the inserted into the pocket 6 and rests with its front in the transport direction edge on a stop 23 of the pocket 6 sheet 2 rests with its rear end on the adjusting element 22. It has a height such that the rear edge 24 of the bottom 2 engaging in the pocket 6 lies in the region above the feed plane of the next sheet 2. As a result, the in Fig. 2 still located on the pad 1 sheet 2 passes with its front edge 25 under the rear end of the engaging in the pocket 6 sheet 2. In this way, the coming of the edition 1 sheets are successively pushed under the stacking part 3 located on the tray.
  • the sheets 2 are fed after their separation in an upstream (not shown) feeder on the support 1.
  • the transport device provided in the support 1 conveys the sheets 2 until they reach the area of the transport rollers 4 or 5. Then the transport of the sheet 2 is taken over by this transport roller. Is the adjusting element 22 in the recessed position of rest ( Fig. 1 ), then take the upper transport rollers 4, the transport of the sheets 2 in the pocket 6.
  • the sheets 2 are fed in a short distance one after the other and stacked on the tray 3.
  • the short distance successively supplied sheets 2 are transported on the tray 3 so far through the upper transport roller 4 until they rest with its front edge 25 on the stop 23 of the pocket 6.
  • the transport roller 13 takes her in Fig.
  • the lower transport roller 5 is not driven.
  • the adjusting element 22 is moved from the rest position into the position of use Fig. 2 raised so that the individual sheets are not stacked, but stacked with each other.
  • the lower transport roller 5 takes over the transport of the respective lower sheet 2.
  • the upper transport roller 4 can be stopped in this case.
  • the sheets 2 are in turn promoted so far into the pocket 6 until they rest with their front edge 25 on the stop 23 of the pocket 6.
  • the transport roller 13 is rotatably driven counterclockwise, which in turn bulged the stack in the region between the transport roller 13 and the pocket 6 V-shaped down and from the oppositely rotating rollers 17 and 18th is detected.
  • These two rollers 17, 18 are driven so that the V-shaped bent part of the stack in the nip 26 is pulled down, so that the stack is folded when passing between the two rollers 17, 18.
  • the adjusting element 22 is advantageously freely rotatable, so that the sheets 2 can be properly stacked with each other on the tray 3.
  • the adjusting element 22 forms an extension of the support 1, with which the rearward in the transport direction of the sheet 2 in the tray 3 is raised so far that the following of the edition 1 sheet 2 under the bent-up end of the sheet 3 on the tray arrives.
  • the transport rollers 4, 5 a very simple switching between over- and under-stacking is possible. If the sheets 2 stacked on the tray 3, then the top sheet 2 of the stack is transported by means of the upper transport roller 4. When Unterstapeln the bottom sheet 2 is the lower Transport role 5 recorded and transported to the bag 6. Since the transport rollers 4, 5 are advantageously suction rollers, the respective uppermost or lowermost sheet 2 can be reliably transported without the remaining, already stacked sheets in the stack are also transported. This ensures that the sheets 2 can be stacked reliably evenly in the stack.
