Definitions

  • the invention relates to a device for separating sheets of plastic, cardboard or the like stacked in a magazine with at least one movable suction device and for transporting the separated sheets to a work station, the sheets in the stack lying essentially horizontally by holders at the lower edge of the magazine are supported and in between the lowest sheet is exposed and is accessible to the vacuum cleaner, a rotatably driven shaft being arranged along at least one of the two lower edges of the magazine as a holder.
  • a separating device of the type mentioned is known from DE-A-24 36 354.
  • a group of approximately 3 to 6 sheets, which are located in the lower region of the magazine, are continuously bent upward in a convex manner. The lowest sheet in each case is removed by rolling it off the stack or by partially rolling the sheet onto one of the successively engaging pairs of take-off cylinders with the inclusion of suction air. In the course of further, fully continuous movements, the sheet is passed on to a central takeover cylinder.
  • the known device is complex, complicated and allows the sheets to be separated only by comparatively strong bending of the sheets, in particular when the bottom sheet from the transport roller onto the removal cylinder pairs and then even onto the central take-over cylinder, each encompassing the curved surfaces partly in opposite directions , is led and guided.
  • the invention is therefore based on the object to provide a separating device of the type described in more detail above, with which the sheets of plastic, cardboard or the like can be reliably separated with simpler means and can preferably be reproducibly brought into engagement with the mentioned suction device in a precise position .
  • the object is achieved in that the shaft is driven in an oscillating manner so that the bottom sheet is brought into a downwardly bent position, the cross section of the shaft is excluded in the region of the length of the sheet to form a shoulder, which The depth of the shoulder is equal to the thickness of the sheet to be separated and that a sucker is arranged to move and retract from below against the sheet approximately in the middle between the edges of the magazine.
  • the bottom sheet falls into the aforementioned shoulder-shaped recess of the at least one shaft and is gripped even at a corrugated sheet edge laterally from the shoulder at numerous points in such a way that with certainty only the bottom sheet when turning the shoulder in the direction of the opposite holder is gripped and subjected to a bending movement due to the shortening of the distance to the opposite holder.
  • the shoulder has a small edge which, prior to engagement with the sheet edge, lies in the direction of the stack height, that is to say is essentially arranged vertically, and a support surface at an angle of approximately 90 ° to which the sheet edge comes to rest.
  • both mutually opposite holders are also designed as partially recessed shafts, which are driven to rotate in opposite directions synchronously with one another.
  • the rotation of the shafts about their longitudinal axes is advantageously oscillating, the arc of the oscillation needing to be only in a range between 10 and 40 °, and in practice it has even been found that a rotation over an angular range of between 20 ° and 30 ° brings good results. This enables the device to separate a large number of sheets per unit of time.
  • the shaft has an approximately semicircular recess in cross section next to the shoulder.
  • a normal wave is round and its outer surface is imagined as a cylinder jacket.
  • the shaft extends under the magazine edge over the entire length of the magazine and beyond its side walls thus certainly longer than the longitudinal edge of the sheet to be separated.
  • the shoulder mentioned can extend beyond the length of the sheet edge and possibly even beyond the corresponding magazine length.
  • the recess which is semicircular in cross section is only provided over the length of the leaf edge, if only for reasons of stability, for exact shaft movements.
  • the shaft In the area of the sheet to be separated, the shaft is flattened, so that a space is created between the waves, which is in any case wider than the smallest distance between two opposite shafts with a circular cross-section without the recess according to the invention.
  • an enlarged space has advantages for the movement of machine elements, as will be described in the following, which could not be moved in a comparably good manner without this enlarged space.
  • the suction cup is translationally movable by means of a first drive, and the first drive is fastened to a second drive for carrying out a rotary movement.
  • the suction cup can be moved in a straight line so that it can be moved from below through the opening of the Magazine can be moved between the opposite holders to the lower surface of the bottom sheet.
  • the first drive can then move the sheet sucked by vacuum in a straight line in the opposite direction to the advancing movement of the suction device downward from the stack. Since this first drive is now attached to a second rotary drive, the suction device can additionally perform a rotary movement together with the attached and separated sheet and transport the separated sheet to another location, e.g. a place where the isolated sheet is removed and subjected to further treatments.
  • the sheets to be separated are rectangular and sometimes have a greater length than width, so that it is expedient to provide correspondingly long shafts as a holder arn magazine below and, accordingly, to arrange several suction cups in a row one behind the other so that the elongated sheet over its entire length can be recorded and held in several places.
  • two so-called first drives spaced apart over the length of the sheet to be separated, although a first drive could also be provided for each suction cup.
  • a translationally movable pressure plate is attached to the first drive, on which the suction pad can be moved in a straight line by a third drive in the same direction as the pressure plate.
  • the above-mentioned machine element is thus a pressure plate in this embodiment, which is namely arranged on the side facing the sheet to be separated and against which this sheet can be placed if the single suction cup or the plurality of suction cups is translational / linear via the third drive mentioned withdrawn relative to the Andrudkplatte.
  • the pressure plate preferably has openings into which the suction cup (s) can be drawn, with the result that the surface of the pressure plate is flush, smooth or flat and the sheet to be separated can be applied accordingly.
  • the third drive mentioned will therefore be conveniently arranged on the back of the pressure plate, which is turned away from the magazine, so that the respective suction cup can be retracted into the outer contour of the pressure plate (with the aid of the third drive), and then the pressure plate with all of it Suckers and their third drives can be rotated by the second drive to remove the separated sheet.
  • the rotationally coordinated rotary movements of the one or two shafts on the magazine edge on the one hand and the transport shaft of the second drive on the other hand are carried out via pneumatically, hydraulically or mechanically controlled levers.
  • At least one wall of the magazine for centering the stacked sheets is arranged to be displaceable perpendicular to the wall plane.
  • one wall of the magazine is pressed gently via an air cylinder in the direction of the opposite, stationary magazine wall, thereby centering the stack of sheets to be separated, with the advantage that the position of each sheet to be separated is always the same and can be reproduced very precisely. This allows you to attach every single sheet to the suction cup in an exact position. This brings considerable advantages for further precise placement of the sheet at subsequent work places.
  • the magazine generally designated 1
  • the magazine is to be thought of as rectangular in plan view and has two longitudinal walls 2, 2 'and two transverse walls 3, 3', each wall consisting of two parallel wall parts, which, however, are not described in more detail here.
  • the walls 2, 2 ', 3, 3' are vertical (perpendicular), so that they can be loaded from above with plastic sheets 6 produced by a cutting device 4 from a web 5.
  • the bottom sheet 6 falls to the lower edges 7 of the magazine 1, below which two shafts 8 are arranged parallel to each other.
  • the axis of rotation 9 of the shafts 8 lies almost in the extension of the inner surface of the walls 2, 2 ', only slightly shifted outside the opening 10, as can be seen more clearly from FIG.
  • the opening 10 extends from the inner lower edge of the edge 7 of the one longitudinal wall 2 to the opposite lower left edge of the right edge 7 of the right longitudinal wall 2 'and is rectangular in plan view in the direction of the arrow 11 (FIG. 2).
  • the respective shaft 8 touches the lower edge 7 of the side wall 2, 2 'of the magazine 1, which results in contact points X (FIG. 3) and also on the opposite side (without designation); in practice small contact areas because the leaves are not 100% rigid and straight. On the contrary, they have to be resiliently flexible, because otherwise the separating device described here would not work.
  • the two shafts 8 are, so to speak, the oats on the lower edge 7 of the magazine 1, on which the sheets 6 are supported.
  • Each suction cup 13 is attached to the outer end 14 of the piston rod 15 of a so-called third drive 16, so that there are as many third drives 16 as suction cups 13.
  • These third drives 16 are fastened to a pressure plate 17, which extends over almost the entire length ( L) and extends transversely to almost the entire width of the sheets 6.
  • This pressure plate 17 thus holds the third drive 16 in each case and enables a relative movement of the suction cups 13 in the direction of the double arrow 18 in a straight line upwards and for retraction vertically downwards.
  • the pressure plate 17 in turn is attached to the outer ends of further piston rods 19 of a so-called first drive 20, which is attached in the form of an air cylinder 20 to a transport shaft 21 which is supported in two bearings 22 as shown in FIG. 2.
  • the axis of rotation of the transport shaft 21 is designated 23.
  • the rotary movement of the transport shaft 21 takes place via a controlled lever 24; the rotation of the respective shaft 8 via a lever 25.
  • the drives of the levers 24 and 25 are not shown.
  • two air cylinders 20 are arranged, so that the pressure plate 17 is securely and reliably held in two places. Separated from the movement of the suction cups 13 with respect to the pressure plate 17, as represented by the double arrow 18, the pressure plate 17 itself can also be moved relative to the transport shaft 21 in the direction of the double arrow 26 via the so-called first drive 20 (air cylinder).
  • the stroke of the translational up and down movement 26 of the pressure plate 17 is greater than the stroke of the straight up and down movement of the suction cups 13 according to the double arrow 18.
  • the rotary movement of the transport shaft 21 in the direction of the curved double arrow 27 in FIG. 1 causes the suction cups 13 to move from the position shown in solid lines in FIG. 1 to the position shown in broken lines, in which the suction cup is denoted by 13 '.
  • a heated plate 28 is shown with a plurality of vacuum openings 29, the vacuum openings on the right surface being thought to be arranged. This heated plate 28 can be moved up and down vertically in the direction of the double arrow 30.
  • the sheets 6 to be separated in the stack 12 are centered by moving the right rear side wall 3 'of the magazine 1 with the aid of an air cylinder 31, which allows the side wall 3' to be displaced in the direction of the double arrow 33 via a piston rod 32.
  • the respective shaft 8 is supported in bearings 34.
  • FIGS. 3 and 4 In FIG. 3, at the bottom left you can see the right end of the pressure plate 17, which has broken off to the left, as well as the isolated sheet 6 above it and the stack 12 in the magazine 1. Under its edge 7 is the shaft 8, the diameter D of which is shown in FIG.
  • the cross section of the shaft 8 shown in FIG. 3 is provided with a recess forming a shoulder 35.
  • Its depth t is as thick as the sheet 6 to be separated.
  • the radially arranged plane 36 of the shoulder therefore represents a very short area, i.e. it corresponds to the height t.
  • This plane appears in the view in FIG. 4 as line 36.
  • the right edge 37 of sheet 6 bears against this shortly before and at the latest after the start of rotation of shaft 8. For clarification, this right edge 37 of the sheet 6, which appears as a line, is shown lying at a somewhat exaggerated distance from the edge 36 in FIG.
  • the shaft 8 at the radial distance from the shoulder 35 is also provided with a semicircular recess 40, which can be seen in FIG. 3 as a partial circular surface, while FIG. 4 shows the empty space 40.
  • This - in cross section - semicircular recess 40 extends only over the length L of the respective blade 6, does not extend over the circular end region d of the shaft 8.
  • the purpose of this semicircular recess 40 is to create a space under the opening 40, as shown in Figure 1. Because of this space, the pressure plate 17 is supposed to be close up can be moved to the bottom sheet 6, so that the excavation path of the suction device 13 from the surface of the pressure plate 17 according to the double arrow 18 can only be very short (small stroke).
  • the space according to the illustration in FIG. 1, in particular on the left side is intended to enable the rotary movement of the pressure plate 17 with the sheet 6 fastened via the suction cups 13 according to arrow 27 to the bottom left.
  • the suction device 13 is pivoted via the second drive 21, 24 with the pressure plate 17 withdrawn into the upper right position shown in solid lines in FIG. Thereafter, the first drive 19, 20 is actuated until the pressure plate 17 has moved upward from the position shown with solid lines to the extent that the piston rod 19 can be seen, which can only be seen in FIG. 1 in the position shown in broken lines as 19 '. Then the respective third drive 15, 16 is actuated so that the suction cups 13 can move up in the direction of arrow 18 up to the underside of the sheet 6 bent by the shafts 8.
  • suction cups 13 grip the underside of the sheet 6, vacuum is applied, and the sheet 6 can be pulled out of engagement by the shoulders 35 of the two shafts 8 by pulling back the piston rod 15 by means of an air cylinder 16 and can be applied downward against the pressure plate 17.
  • the first drive is switched on again, the piston rods 19 pull the pressure plate radially back, reducing the turning radius.
  • the second drive is then switched on by rotating the transport shaft 21 in the direction of the curved arrow 27 (FIG. 1) downward by about 90 ° so that the pressure plate assumes the dashed position. In this one can see the pressure plate 17 'with the sheet 6' held by the suction cups 13 '.
  • the first drive has meanwhile been switched on, so that the piston rod 19 'is moved radially outward, so that the blade 6' comes into contact with the surface of the heated plate 28.
  • the vacuum can now be applied via the nozzle openings 29 while the suction devices 13 'are being ventilated.
