Definitions

  • the invention relates to a sheet leading edge separator with several double suction cups arranged side by side for cyclical conveying von Bogen, the double suction cups by a cam coupling gear driven movements on a closed path in the conveying direction run the bow and back while doing the double suction in one movement cycle comprising two work cycles by one work cycle successively moves into the area of the leading edge of a stack of sheets to acquire an arch with a four-bar link of the cam coupling gear, the two approximately horizontally running gear members has one end through a double suction cup Suction pads are connected together and their other ends by one of a first cam mechanism essentially horizontal movably drivable coupling are connected to one another, one the horizontally extending transmission members continue from a second Cam gear is drivable substantially vertically.
  • a sheet leading edge separator of the type mentioned is from the
  • the first cam mechanism consists of a swing parallelogram hinged to the paddock, one of which Swing arm is pivotally driven by a cam.
  • This structure has the disadvantage that a large number of components, in particular on swingarms and bearings is required, which requires a lot of space, are expensive and prone to failure.
  • the object of the invention is therefore a sheet leading edge separator to create the type mentioned at the simple, inexpensive Set up a straight vertical lifting of the arches with simultaneous Tilting the suction surfaces of the double suction cup lifting the bow allows.
  • the double suction device In addition to the small and therefore less prone to failure of the number of components when the double suction device is lifted in a straight line, its sheet is removed from the sheet stack lifting suction surface tilted so that it at its in the conveying direction front side is raised more than on the opposite side Page.
  • the suction surface thus extends in its inclination approximately according to the inclination of the one hanging freely on the sheet stack Arc area, causing accidental release of the arc from the suction surface.
  • the cam disc of the first cam mechanism can be in the middle range act on the rocker along its length.
  • a roller can be freely rotatably mounted on the rocker arm radially circumferential surface on the radially circumferential contour of the Cam of the first cam mechanism is in contact.
  • the second cam mechanism can be a substantially vertically extending one have second coupling, which is driven by a rotatable cam of the second cam mechanism can be driven approximately vertically.
  • the second coupling is preferably at one end with one the gear links of the quadrilateral joint and articulated on their other End of the cam disc of the second cam mechanism approximately vertically movably actable.
  • the second coupling second roller can be freely rotatably mounted with its radially rotating Shell surface on the radial circumferential contour of the cam disc second cam mechanism is in plant.
  • roller rocker near the cam of the second Cam gear articulated to the second coupling.
  • Another vertical guide can also be that the second Couple with one end to one of the gear links of the four-bar linkage articulated and at its second end by a double-armed Swing arm is approximately vertically movable, the double-armed Rocker is freely pivotable about a second fixed pivot axis, with the free end of their one swing arm at the second end of the second coupling articulated and one at the free end of their second Swing arm with freely rotatable second roller on the radially rotating one Contour of the cam disc of the second cam mechanism in the system is.
  • a particularly low-component construction and a particularly small installation space is achieved when the cams of the first and the second Cam gear on a common rotatably drivable drive shaft are arranged rotatably.
  • the front edge separators shown consist of at least two units spaced side by side, like one of them is shown in Figure 1 and Figure 3.
  • These units each have a double suction device 1 and 1 ', one has upper suction surface 25 and a lower suction surface 26.
  • the double suction cup 1 is fixedly arranged on a suction coupling 9, at a distance from the two gear members 7, 8 which extend approximately horizontally to one another are articulated, the ends of which also face away from the suction coupling 9 are hingedly connected to one another by a first coupling 10, so that a quadrangle 6 is formed.
  • the first coupling 10 is fixed in one piece with a substantially vertical extending rocker 11 of great length connected to its the first coupling 10 opposite end about a fixed pivot axis 12 is pivotally mounted.
  • a roller 14 can be freely rotated approximately in the central region of the rocker 11 stored, the radial circumferential surface 15 on the radial circumferential contour 16 of a cam 13 of a first cam mechanism is in plant.
  • cam 13 Through the drive shaft, which can be rotated in one work cycle 24 arranged cam 13 are the rocker 11 and with it the Quadrilateral 6 and the double suction cup 1 essentially horizontal movably drivable.
  • FIG. 1 In the embodiment of Figure 1 is approximately in the central region lower transmission link 8 articulated a second coupling 17, which is in extends substantially vertically downwards and at its the transmission link opposite end carries a freely rotatably mounted second roller 19.
  • This roller 19 is with its radially circumferential surface 20 on the radial circumferential contour 21 of a cam 18 of a second Cam gear in system, the second cam 18 next to the first cam 13 also arranged on the drive shaft 24 in a rotationally fixed manner is and the second coupling 17 and with it the four-bar linkage 6 and drives the double suction cup 1 essentially vertically movable.
  • one end is one Roller rocker 23 hinged to the second coupling 17, the other End of the rocker arm 23 about a second fixed pivot axis 22 free is pivotally mounted.
  • a second coupling 17 articulated which extends substantially vertically downwards.
  • the double-arm swing arm 28 On her second The end 17 of a double-armed rocker 28 is approximately vertical movably acted upon, the double-arm swing arm 28 um a second fixed pivot axis 22 is freely pivotable.
  • the free The end of its one swing arm 29 is the double-arm swing arm 28 articulated at the second end of the second coupling 17 and via one at the free end of their second swing arm 30 freely rotatably mounted second Roller 19 'on the radially circumferential contour 21 of the cam 18 of the second cam mechanism in the system.
  • the first cams 13 and second cams 18 of the two juxtaposed units of the same structure as in FIG. 1 or shown in Figure 3, are arranged offset by 180 ° to each other. This leads to a movement cycle involving two work cycles of the sheet leading edge separator the double suction cup 1 first with its lower suction surface 26 the top sheet 2 in the area the stack leading edge 4 of a sheet stack 5 is detected and at least largely lifts vertically.
  • the square 6 is the Double suction cup 1 tilted so that its lower suction surface 26 from its to Surface of the sheet stack 5 parallel position in a conveying direction 3rd is pivoted higher in the front than in the rear.
  • the double suction device 1 moves over the front area of the sheet stack 5 upwards, so that the double suction cup 1 'is then under the sheet 2 raised by the double suction device 1 over the sheet stack 5 move and can capture another sheet 2 "'.
  • the double suction device 1 ' carries out the inputs for the double suction device 1 described lifting movement, while the double suction device 1 the input described movement of the double suction device 9 'is carried out.
