Definitions

  • the invention relates to a device for straight pushing a stack with a bumper pointing in the stacking direction, at the end pointing in the stacking direction, a bumper plate is arranged, and with a displaceable in the pushing direction, connected to carry out the pushing movement with drive means in which to adjust the position of the Bumper plate relative to the bracket, the bumper for format adjustment is slidably mounted in the stacking direction and its position is adjustable.
  • Such a device is known from DE-GM 75 13 266.
  • plates attached to straight bumpers are pushed towards and then moved away again for straight butting.
  • This back and forth movement is transmitted by a cam drive to a bearing bush that is displaceable relative to the machine side frame.
  • a positionable linear bumper designed as a spindle, is adjustably mounted in its position.
  • the straight bumper is moved in its position with respect to the bearing bush.
  • such a straight bumper In order to enable format adjustment over a larger area, such a straight bumper must be designed as long as possible.
  • the invention is based on the problem of creating a device for straight butting a stack according to the preamble of the main claim, with which a secure format adjustment over a wide format adjustment range is possible in a space-saving manner.
  • this problem is solved by an embodiment of such a device according to the characterizing features of claim 1.
  • a small sheet format with a large length of the straight bumper can be processed.
  • processing with a short length of the straight bumper is possible.
  • the straight bumper does not represent an additional safety risk for people, additional, space-consuming and obstructing cladding can be omitted.
  • An embodiment according to the features of claim 2 represents a particularly simple preferred embodiment, in which a functionally reliable stack alignment over a large format adjustment range can be carried out with little effort is possible. Stable storage can be maintained across the entire format range.
  • the training according to the features of claim 3 enables a particularly advantageous and safe format adjustment.
  • the inventive design according to the features of claim 4 represents a particularly simple space-saving design of a device for pushing a stack straight.
  • the straight bumper With a common drive means, the straight bumper can be adjusted in its position for holding and its length can be changed.
  • the inventive device according to the features of claim 5 allows a simple design of the means for changing the length of the straight bumper. Since the means for changing the length participate in the straight butt movement in such a device, they can be in permanent operative connection with the straight bumper without additional, expensive, extensive coupling elements.
  • FIGS. 1 to 6 The invention is explained in more detail below using an exemplary embodiment, as shown in FIGS. 1 to 6.
  • Fig. 1 shows a last printing unit 2 downstream in the sheet conveying direction 1 of a sheetfed offset printing press, in which the paper sheets placed on a delivery stack 3 are secured by means of brackets 40 attached to racks arranged in the side walls 5 in the stacking direction, with straight bumper plates 4 articulated thereon in its lateral side Position.
  • the profiled rack 15 is slidably mounted in a hollow shaft 14.
  • the hollow shaft 14 is provided in its lower region with a longitudinal groove 39 formed parallel to its axis, the two ends of which are formed as stop surfaces 18 and 19.
  • the hollow shaft 14 is rotatably axially displaceable in a bearing bush 6 fastened in the side wall 5 and also axially displaceably, rotatably mounted hollow shaft 7.
  • the two hollow shafts 7 and 14 and the rack 15 are arranged concentrically.
  • the hollow shaft 14 is profiled on its outer circumference and in a bushing 16 fastened in the hollow shaft 7 with the outer profile of the hollow shaft 14 Correspondingly designed inner profile rotatably mounted axially.
  • a bearing block 23 is fastened on the end region of the hollow shaft 7 pointing from the side wall 5 to the stack side.
  • an adjusting shaft 25 is rotatably and axially fixed beneath the rack 15.
  • a gearwheel 24 is attached to the adjusting shaft 25 and meshes with the rack 25 through a longitudinal groove of the hollow shaft 7 and through the longitudinal groove 37.
  • the adjusting shaft 25 is aligned perpendicular to the axis of the rack 15 and rotatably, axially fixed at its end opposite the gear 24 in a bearing bush 29.
  • the bearing bush 29 is mounted in a slot 28, which is designed as a sliding bearing, on a holding projection 27, which is fastened to the side wall 5, so that it can be displaced in a rotationally fixed manner parallel to the rack axis.
  • a handwheel 26 is fastened on the adjusting shaft 25.
  • the adjusting shaft 25 can be locked in a set rotational position with respect to the bearing bush 29 by means of a locking screw 30.
  • a driving plate 8 is fastened on the end of the hollow shaft 7 that points away from the delivery stack 3 through the side wall 5.
  • a driving roller 9 is rotatably mounted radially to the hollow shaft 7.
  • a compression spring 10 is mounted concentrically with the hollow shaft 7 between the drive plate 8 and the bearing bush 6.
  • the roller 9 is in constant contact with the compression spring 10 with an axial cam segment disc 11 driven by the printing press drive in a known manner about a pivot pin 12 of a lever 13 in a reciprocating movement.
  • the locking screw 30 is first loosened, then the handwheel 26 and thus the gearwheel 24 are rotated, as a result of which the toothed rack 15 is displaced in its axial position. If the sheet format is reduced, the rack 15 is shifted in its position towards the sheet stack with entrainment of the hollow shaft 14 until the stop 18 of the hollow shaft 14 strikes the end face of the guide bush 16. When the gear wheel 24 is rotated further, the gear rack 15 is now displaced with respect to the hollow shaft 14 in the direction of the stack until the end region 20 of the gear rack 15 reaches the meshing region of the gear wheel 24.
  • the gear wheel is rotated in the opposite direction, whereby the rack 15 is first pushed away from the sheet stack, taking the hollow shaft 14 with it, until the stop 19 of the hollow shaft 14 strikes a stop, not shown, on the facing end face of the hollow shaft 7 outside the area of influence of the gear wheel 24.
  • the gear wheel 24 is rotated further, the toothed rack 15 is displaced away from the sheet stack with respect to the hollow shaft 14 until the straight arc joint holder 40 strikes the end face of the hollow shaft 14.
  • the handwheel 25 is locked again using the clamping screw 30. For this phase-wise entrainment of the hollow shaft 14, lower frictional forces act between the hollow shaft 14 and the hollow shaft 7 than between the hollow shaft 14 and the rack 15.
  • the slot 28 is designed so that a sliding movement of the bearing bush 29 relative to the Bracket 27 over the entire intended stroke range of the straight butt plate 4 is made possible.
  • a pneumatic cylinder 32 with a piston rod 33 radially aligned with the hollow shaft 7 can be fastened to a holding projection 31 on the outside of the side wall 5 on the outside of the side wall 5.
  • a lever 35 on a bearing pin 34 is on the piston rod 33 pivoted.
  • the lever 35 is double-armed and is pivotally mounted with its one arm about a pivot pin 36, which is fastened in the retaining projection 31.
  • the other arm of the lever 35 is formed with a right-angled stop 37 which corresponds to a right-angled stop surface 38, consisting of a stop surface which faces away from the side wall 5 and a circumferential surface.
  • a hollow shaft-shaped pin 41 can have its end face on the end face pointing away from the side wall 5 the drive plate 8 are pressed mechanically, electrically or pneumatically and push them out of the area of influence of the curve segment.
