Definitions

  • the invention relates to a sheet feeder according to the preamble of the claim.
  • a not sufficiently precise system of the type described can result, in particular, in sheet feeders with a non-stop device, namely in that a residual sheet stack that is already in the sheet feeder and largely processed has a main sheet stack that is initially completely independent of it and newly introduced into the sheet feeder a whole stack is combined.
  • a sheet feeder is known for example from the document DE 26 37 086 B1.
  • a remaining sheet stack rests temporarily on supporting bars oriented in the processing direction, which are supported by at least two crossbeams arranged transversely thereto and carried by a lifting device and are pulled against the processing direction in order to combine the remaining sheet stack with a main stack placed against the supporting bars from below.
  • a stack stop is provided, which can be set against the remaining sheet stack. This stack stop can be fixed in a position once set and thus provides support for a remaining sheet stack against its displacement against the processing direction.
  • a device is known by means of which an upper region of a first stack side surface of a stack of sheets arranged in a sheet feeder can be aligned with a stop assigned to this stack side surface.
  • a stop assigned to this stack side surface.
  • the stack side surfaces mentioned are those which, even in the case of a sheet feeder equipped with a non-stop device, are usually not coated with components thereof, namely stack side surfaces pointing in directions transverse to the processing direction.
  • the invention has for its object to design a generic sheet feeder so that disruptions to the operation of a sheet processing machine can be avoided, insofar as this Faults are caused by the fact that a stack of sheets in the feeder of such a machine is not sufficiently close to the front stops customary in such feeders. This object is achieved with a device specified in the claim.
  • a sheet feeder according to the invention also proves to be advantageous insofar as only relatively low requirements are placed on the pre-stacking of sheet stacks and trouble-free operation in the aforementioned sense is guaranteed even without manual straightening work by an operator.
  • a stack space of the sheet feeder is shown only schematically by the reproduction of a remaining sheet stack 1 and a main sheet stack 2 with dash-dotted lines in a phase of the union in which the remaining sheet stack 1 with its lowermost sheet on horizontally arranged lattice bars 3 one designated 4 overall Sliding device sits and the main sheet stack 2 is placed with its uppermost sheet from below against the bars 3, which are here in the dash-dotted, compared to the drawn with full lines in the longitudinal direction of the bars 3 shifted position.
  • the free ends of the lattice bars 3 projecting beyond the first side surface of the stack arrangement facing the machine are supported in a known manner by means of an auxiliary cross member 5 which can be seen in cross section in FIG. 1.
  • the main stack 2 is seated on a stack support plate 6 with its lowermost arch.
  • a sheet stack sitting on such a stack support plate is lifted during the printing by known lifting mechanisms to the same extent as the height of the sheet stack decreases until it finally becomes a remaining sheet stack.
  • the remaining sheet stack 1 with its lowermost sheet before being combined with the main stack 2, also initially sits on one in FIG. 1 with 6 designated stack support plate until after removal of the remaining sheet stack 1 by means of the bars 3 in a known manner with lowering by means of the lifting mechanisms mentioned.
  • This stack support plate 6 is provided on its horizontally oriented upper side with mutually parallel grooves 7.
  • a group of the parallel bars 3 is combined to form a rake 8.
  • the cross sections of the bars 3 and the grooves 7 are coordinated so that the bars 3 can be inserted in the longitudinal direction in the grooves 7 so that the remaining sheet stack 1 is underpinned by the bars 3 in a phase of union.
  • a side part is formed with a guide rail 9 and an end leg of a frame 12 is formed with the stop rail 10.
  • the frame 12 which is detached from the displacement device 4 in FIG. 3 and shown in a position corresponding to the position in FIG. 2, is furthermore attached to a front end located on the left in FIG. 3 by means of a first cross strut and to an in FIG Fig. 3 right rear end of the guide rail 9 stiffened.
  • a respective guide rail 9 is composed of an upper guide rod 15 and a lower guide rod 16.
  • the respective upper guide rod 15 serves as a straight guide for the rake 8, which is detached from the displacement device 4 in FIG. 7 and is shown in a position corresponding to the position in FIG. 2.
  • This rake 8 is formed from a bridge 17 in which the bars 3, as can be seen most clearly in FIG. 8, are clamped at one of their ends.
  • the bridge 17 extends transversely to the longitudinal direction of the bars 3 and has bridge bearings in the form of straight guide profiles 18 which encompass a respective upper guide rod 15 of one of the guide rails 9.
  • For one of the straight guide profiles 18, their connection to a respective upper guide rod 15 is shown in FIG. 9, the upper and lower guide rods 15 and 16 each being shown in broken lines.
  • the guide rails 9 and the bars 3 run parallel to each other, so that the rake 8 is slidably mounted in relation to the frame 12 in the longitudinal direction of the bars 3.
  • an automatic displacement of the rake 8 relative to the frame 12 is provided.
  • the tapes of which, as indicated by dash-dotted lines in FIG. 10 are connected to the bridge 17 of the rake 8.
  • Fig. 7 corresponding schematically shown and shown in dash-dotted lines connecting means for connecting the bands of the band cylinder 19 to the bridge 17 with 20.
  • the frame 12 is in turn slidably mounted in the longitudinal direction of the bars 3 and in the horizontal transverse to the longitudinal direction of the bars 3.
  • the displacement device 4 is equipped with a cross slide 21 for this purpose.
  • the cross slide 21 shown in FIG. 11 and displaced in a position corresponding to the position in FIG. 2 extends transversely to the bars 3 from a guide rail 9 on a first longitudinal side of the frame 12 to the opposite guide rail 9 on a second longitudinal side of the frame 12 and has the straight guide profiles 22 (FIGS. 9, 10) provided on the rake 8.
  • These straight guide profiles 22 encompass a respective lower guide rod 16 of a respective guide rail 9.
  • the frame 12 is thus opposite the cross slide 21 and the rake 8 slidable relative to the frame 12 in the longitudinal direction of the bars 3, the cross slide 21 in turn being equipped with further straight guide profiles 23 oriented transversely to the bars 3 (see FIGS. 12, 13), which will be discussed in more detail below.
  • automatic adjusting means in the form of a piston having a first cylinder 26 and a second cylinder 27 and acting between the cross slide 21 on the one hand and the frame 12 on the other hand are Cylinder arrangement provided.
  • the first cylinder 26 is flanged to a guide head 28 which is guided by means of a slideway 29 fastened to the cross slide 21 in the longitudinal direction of the lattice bars 3, while the piston rod of this first cylinder 26 is articulated to a bracket 30 fastened to the cross slide 21 (see FIG. 11, 13, 14).
  • the second cylinder 27 is articulated at one end to the guide head 28, while the end of the piston rod of the second cylinder 27 facing away from this end is connected in an articulated manner to a further bracket 31, which in turn is attached to the frame 12.
  • a positioning device in the form of a lifting device carrying the displacement device 4 is provided for setting the desired height positions of the stop rail 10, and is used at the same time to lower and raise the rake 8.
  • This lifting device has a horizontal truss arrangement 24 oriented transversely to the lattice bars 3.
  • a linear actuator 33 is fastened to the truss arrangement 24 and a push rod of the linear actuator 33 is articulated to a further bracket 34, which is fastened to the cross slide 21.
  • FIGS. 15, 16 and 17 each show one end of the crossbar arrangement 24 of the positioning device which can be seen in its entirety in FIG. 18.
  • This truss arrangement 24 is connected in a manner not shown in more detail to a lifting drive 36 (see FIGS. 1 and 18) via a traction means 35, such as a chain or a toothed belt, and can be moved vertically along a lifting frame 32.
  • a traction means 35 such as a chain or a toothed belt
  • the guideways 37 are designed as rectangular profile bars, the cross sections of which can be seen in dash-dot lines in FIG. 15.
  • a respective end of the truss arrangement 24 is provided with rollers 38 and 39 which roll on the guideways 37 and are arranged such that they fix the truss arrangement 24 transversely to the longitudinal direction of the guideways 37.
  • the lifting frame is of self-supporting construction and, as can be seen most clearly in FIG. 1, is set up outside the stacking space, which is shown schematically in FIG. 1 by the dash-dot representation of the remaining stack 1 and main stack 2.
  • This lifting frame 32 is composed of a first column 40, a second column 41 and a yoke 42 connecting the upper ends of these columns 40 and 41 and thus forms a two-legged portal (see FIG. 18).
  • a respective column 40 or 41 is formed by means of a hollow profile.
  • the traction means 35 provided for lifting and lowering the crossbar arrangement 24 are shown in the exemplary embodiment of toothed belts.
  • Deflection wheels 43 which are toothed in accordance with the toothed belt are mounted on the yoke 42 and are wrapped around by a respective toothed belt.
  • a first run of a respective toothed belt carries the cross-member arrangement 24 and a second run carries a counterweight 44, which is immersed in the hollow profile of a respective column 40 or 41.
