Definitions

  • the present invention relates to a device for unstacking a pallet loaded with a stack of paper sheets, with which the stack is successively removed from the stack.
  • the object of the present invention is therefore to create a device with which the de-stacking of paper stacks on pallets can be carried out mechanically and with little physical effort.
  • the machine must be designed so that it can be operated fully automatically in a simple manner using the usual microprocessor technology.
  • the device has a stationary stand 1, consisting of four vertical struts 2 and further horizontal cross struts 3 connecting them.
  • Spindles which are not visible in the drawing are rotatably mounted in the vertical struts 2 and can simultaneously be driven by a motor (not shown).
  • the spindles are connected to one another by gears arranged in the cross struts 3 with end-angle gears.
  • a lift 4 is mounted on the spindles, the one rotating Spindles are raised or lowered.
  • the lift 4 is provided with supports 5, which are preferably assigned a drivable conveyor belt and which serve to receive a pallet 7 loaded with a paper stack 6.
  • the length of the stroke of the lift 4 is equal to the length of the vertical displacement path of the pallet 7.
  • the removal of partial stacks 6 serves a removal belt 8 which reaches up to close to the vertical displacement path of the pallet 7.
  • the conveyor belt 8 is a telescopic belt. The position of its start can therefore be set close to the stack 6 regardless of the stack format.
  • a first carriage 9 is mounted on a horizontal rail 13 so as to be displaceable in the direction of the conveyor belt 8, which carries a stop 10 which can be adjusted vertically between a working and rest position using a linear motor 14.
  • This interacts with a sensor 11, which is displaceable along a vertical measuring scale 12.
  • the sensor 11, which can also be moved horizontally between a working and rest position, engages over the edge of the pallet protruding from the stack 6 in its working position and is carried along by the pallet 7 along the measuring scale 12 when the elevator 4 is raised. In the rest position, the sensor 11 is outside the vertical displacement path of the pallet 7.
  • the stack height H must be determined precisely before the de-stacking begins.
  • the sensor 11 is brought into the working position and the lift 4 is raised from its lowest position, until the stack 6 abuts the stop 10, which is also in the working position.
  • the sensor 11 is carried along the measuring scale 12 and signals the height H of the stack 6 when the lift comes to a standstill by means of optical or electrical signals.
  • the number of partial stacks 6 'to be removed can now be calculated with the height H' and removal can be carried out automatically or manually.
  • the stop 10 and the sensor 11 are no longer required for the process of removing the partial stack 6 and moved into their rest position.
  • the carriage 9 is driven forward and backward by a motor (not shown) attached to it.
  • a bracket 15 Fixed to the carriage 9 is a bracket 15 which carries a separating tongue 16.
  • This separating tongue 16 is at the level of the conveyor plane 8 'of the conveyor belt 8 or slightly above.
  • the console 15 with its leading flank 23 and the separating tongue 16 form an ejector, which pushes the uppermost partial stack 6 'onto the removal belt 8 when the carriage 9 advances, the separating tongue 16 forming the lower limit of the ejector or partial stack 6' .
  • two horizontal guide rods 17 are attached to the stand 1, on which a second carriage 19, which can be driven with a band cylinder 18, is slidably mounted to and fro.
  • This second carriage 19 carries two wedge-shaped hold-down devices 20 which are spaced apart from one another and which are seen on the left and right in the direction of movement the separating tongue 16.
  • Both hold-down devices 20 can be tilted obliquely downwards from their horizontal or slightly upward position on a horizontal axis 21 on the second carriage 19 with their wedge cutting edge facing the stack 6. Their position is determined by a cylinder piston unit 22.
  • the lift 4 is first raised until the stack 6 projects beyond the level of the separating tongue 16 by the height H '.
  • the first carriage 9 is moved against the conveyor belt 8 until the separating tongue 16 is in the stack 6 and spreads it between two sheets of paper.
  • the separating tongue 16 penetrates so far into the stack 6 until the leading edge 23 of the bracket 15 bears against the part stack 6 'to be separated (FIG. 3).
  • the second carriage 19 is moved against the conveyor belt 8 and the hold-down devices 20 are pushed into the gap produced by the separating tongue 16 (FIG. 4). 4, the hold-down device 20 has reached the position shown in FIG. They remain in this tilted position during the subsequent work step and press on the top paper sheet of the remaining stack 6. They exert a restraining force on it.
  • the first carriage 9 is moved further against the removal belt 8 until the flank 23 of the ejector 15, 16, 23 reaches the beginning of the removal belt.
  • the ejector 15, 16, 23 pushes the partial stack 6 'lying on the separating tongue 16' in front of it onto the discharge belt 8.
  • the separating tongue 16 is provided with blown air openings. Through this, blown air is pressed into the wedge-shaped gap during the entire separation process, so that an air cushion forms in the parting plane between the part stack 6 'to be separated and the rest stack, which facilitates the lateral pushing away of the part stack 6'.
  • the conveyor belt 8 has a surface with a pronounced friction structure. As soon as during the pushing away of the partial stack 6 to be separated, the preceding lower edge of which strikes the removal belt 8, it is grasped with friction and removed from the remaining stack, thereby supporting the pushing action of the ejector 15, 16, 23.
  • the bracket 15 is mounted on the carriage 9 so as to be vertically displaceable by means of a guide 24 and is held in its lower position shown in the drawing by a pneumatic spring 25.
  • the stop 10 is brought down by the linear motor 14 into its working position.
  • the carriage 9 is moved so far against the conveyor belt 8 that the cutting edge of the separating tongue 16 lies over the projecting edge of the pallet 7.
  • the lift 4 is raised until the last partial stack 6 'at the stop 10 and the separating tongue 16 is present at the edge of the pallet.
  • the stop 10 is raised to the rest position (dash-dotted) and the lift 4 by a few Raised millimeters further.
  • the separating tongue 16 is also lifted and the pneumatic spring 25 is compressed, which thereby presses the separating tongue onto the edge of the pallet.
  • the carriage 9 is moved against the conveyor belt 8 and the last partial stack 6 'pushed onto it by means of the ejector 15, 16, 23.
  • the force exerted by the pneumatic spring 25 on the separating tongue 16 ensures that the separating tongue 16 slides under the bottom sheet of the last partial stack 6 'or between these and the pallet 7.
  • the lift 4 is lowered again and the empty pallet 7 is exchanged for a loaded one, whereupon the workflow described is repeated.
  • the separating tongue 16 can be reliably brought over the projecting edge of the pallet, but after ejecting the second-last sub-stack 6', a sensor 42 fastened to a carriage 42 before moving the separating tongue 16 forward 43 brought into contact with the facing side surface of the last partial stack 6 '.
  • the carriage 42 can be moved on the rail 13. So that when the ejector 15, 16, 23 is pushed forward, the preceding end of the separating tongue 16 can be stopped exactly above the projecting edge of the pallet, an upward-facing photoelectric transmitter 44 and receiver is attached to the front end of the sensor, which generates a stop signal as soon as the separating tongue 16 cuts its light barrier. Then the carriage 42 with the sensor 43 in the Starting position moved back and the lift 4 raised until the protruding edge of the pallet 7 abuts the separating tongue 16 and lifts it by a few millimeters.
  • the console 15 here consists of two parallel, spaced plates 15 ', 15 ⁇ , which are connected at the top by a plate 45 firmly connected to the guide 24 and at the front by a plate 46 forming the flank 23. Between the plates 15 'and 15 ⁇ extend two firmly connected guide rods 49 and 50, on each of which a bearing bush 51, 52 is axially displaceable. A support plate 53 is fixedly connected to the bearing bushes and is displaceable. A support plate 54 is attached to this, on which a pneumatic cylinder 56 hangs pivotably about an axis 55.
  • An axis 57 also passes through the support plate 53, to which an angle lever 58 is articulated.
  • the other end of the angle lever 58 is pivotally connected to the end of the piston rod of the cylinder 56 by a pivot pin 59.
  • the separating tongue 16 is firmly screwed to the angle lever 58.
  • the cylinder 53 is pressurized with compressed air in such a way that it holds the separating tongue 16 in a horizontal, unstable, lightweight position.
  • Adjusting screws 61 are screwed into two lateral ribs 60 which are firmly connected to the carrier plate 53. These limit a tilting of the preceding end of the separating tongue 16 downward, whereas the stop surface 62 limits an upward tilting of the separating tongue 16.
  • a force acts on the free end of the separating tongue from above or below, it can, against dodge the equilibrium force generated by the cylinder 56 up or down until it comes to rest either with the adjusting screws 61 or with the stop 62.
  • a force deflecting the separating tongue 16 occurs when the foremost point of the separating tongue 16 hits a sheet of paper and not between two sheets of paper during the advance for unstacking.
  • the separating tongue 16 which is held in an unstable equilibrium position, attempts to move up or down, its deflection movement being limited by the upper or lower bow. As a result, it can slide between the hit sheet on the one hand and the adjacent sheet on the other hand, without injuring the hit sheet.
  • an electric motor 63 is attached, which drives an eccentric pin 65 via a gear 64, which moves a push rod 66 which extends through a slot opening 67 to and fro.
  • the other end of the push rod 66 is articulated on an axle 68 which is fixedly connected to the support plate 53.
  • the carrier plate 53 With the engine 118 running, the carrier plate 53 is moved back and forth on the guide rods 49, 50 by the crank mechanism described. It carries out a lateral oscillating movement, the frequency of which can be set via the speed of the motor 63.
  • the eccentric radius of the eccentric pin 65 and the length of the push rod 66 are adjustable for adjusting the size of the stroke.
  • the console 15, 16, 23 is moved to unstack the stack 6, so that the separating tongue 16 penetrates into the stack 6, the separating tongue 16 is laterally moved back and forth during this advance (at least during the period between the first contact of the separating tongue 16 with the stack 6 and its insertion between two sheets of paper). If (as described) the separating tongue 16 hits a sheet of paper, the lateral oscillating movement favors a deflection of the preceding end against the equilibrium force of the cylinder 56, which promotes the penetration between two sheets and eliminates the risk of injury to the sheet of paper hit.
  • the separating tongue 16 In plan view it is in the shape of a scoop and is attached to the bracket 15 or the angle lever 113 with its stem-shaped end. The bottom is essentially flat. In the rear area, the upper side forms a plane 26 parallel to the underside and, starting from the edges 27, 28, has surfaces 31, 32 sloping both towards the sides 29 and towards the preceding edges 30.
  • the front part of the separating tongue 16 is tapered in a wedge shape in the direction of movement on the one hand and on the other hand transversely thereto.
  • the surfaces of the separating tongue 16 are polished throughout and their leading edges 30 are rounded, the radius of curvature being 0.15 to 0.45 millimeters, preferably 0.3 millimeters.
  • the underside of the separating tongue 16 is provided with a groove 33 which is rectangular in cross section and which intersects the surface 32 at the edge 34.
  • a sword 35 is inserted into this groove 33, the underside of which is essentially coplanar with the flat underside of the separating tongue 16.
  • the sword 35 towers over the leading edges 30 and tapers in the vertical and horizontal directions in a wedge shape.
  • the wedge angle ⁇ is 30 ° to 60 °, preferably 45 ° to 55 °.
  • the wedge angle is less than 15 °, preferably 5 ° to 10 °.
  • the wedge-shaped taper extends up to a line 36 (FIGS. 8 and 9).
  • the sword 35 is uniformly thick and rounded in plan view.
  • the width of the sword (seen in plan view) is at most 50 millimeters, preferably 30 millimeters.
  • the thickness of the flat part 37 of the sword 35 from the line 36 to the sword end is 0.2 to 0.8 millimeters, preferably 0.35 millimeters, these edges also being rounded.
  • the visible surfaces of the sword 35 are polished like the other surfaces of the separating tongue 16.
  • the preceding edges 30 of the separating tongue 16 are slightly swept backwards.
  • the angle enclosed by the edges 30 is 60 ° to 150 ° and is preferably around 120 °.
  • the separating tongue 16 is provided with blown air channels 38, which can be connected to the operational compressed air network via the connections 39 and flexible hoses (not shown).
  • the blown air channels 38 are connected to numerous blown air openings 40 in the surface of the separating tongue 16.
  • the sword 35 is provided with a groove-shaped channel 41 (which can also be omitted), which is connected to the blown air channels 38.
  • the channel 41 comes to the surface at the edge 34 and thus opens upwards.
  • the blown air channels 38 are each supplied with blown air during the advance of the separating tongue 16, thereby forming an air cushion during their penetration into a stack 6 between the separated layers of paper, which facilitates the lateral pushing away of the partial stack 6 '.
