Definitions

  • the present invention relates to a device for separating stacked Plates.
  • the invention relates in particular coated and uncoated chipboard, OSB, MDF and others Fiberboard, gypsum boards, mineral boards and more generally wood boards, Plastic, metal and materials composed thereof.
  • the invention is based on the technical problem of a device and a method specify a simple, reliable and efficient separation of Allow plates from a stack.
  • the invention is directed to a device for removing plates from a stack comprising: an alignment device for laterally aligning plates in the stack and a transport device for removing aligned plates from an upper side of the stack, characterized in that the alignment device is adapted thereto to align stacked overhead of the plates in one direction, and a method for removing plates from a stack with such a device and the method steps of: laterally aligning plates in the stack and removing aligned plates from an upper side of the stack, characterized in that the plates are located in the stack at the top in one direction be aligned offset from each other.
  • the basic idea of the invention is a number of in the stack overhead Align plates against the prior art not exactly superimposed, So with vertical side edges of the stack, but offset from each other.
  • the plates can be offset in one, but also in two directions which lie in the plane of the flatness of the plates. It turned out that this procedure leads, in contrast to the prior art, that the overlapping plates in the upper part of the stack no longer take the same positions in relation to the plane of their flatness, themselves However, with this form of alignment can achieve significant benefits.
  • the plates insofar as they are sensible and necessary for losing weight, even in the staggered arrangement to align properly, and with respect to the different upper layers different.
  • the alignment is particularly useful, to avoid unnecessarily long creeping paths of the transport device or a reliable gripping or suction of the plates by the transport device to guarantee.
  • the staggered arrangement offers much improved possibilities the per se known blowing of side edges of the upper plates in the stack before losing weight.
  • the latter is not a necessary feature of the invention but merely an advantage in the context of an optional embodiment.
  • the offset alignment can generally be achieved by an abutment against an abutment body getting produced.
  • the alignment device is with a contact body equipped, one according to the desired offset orientation having sloping contact surface.
  • the plant body is guided by the alignment device moved up to the upper plates in the stack so that the sloping contact surface with the desired side edges of the plates in contact comes and shifts the plates so that they eventually pass through each attachment arranged offset at the oblique contact surface in the desired manner are.
  • the contact body is substantially horizontal and translatory process.
  • At least the contact surface is preferably made of elastic Plastic to prevent damage when contacting the edges. The Hardness of the plastic may be due to the forces occurring in the alignment, the desired alignment accuracy and the resilience of the edges adjusted become.
  • a pneumatic element which may be supported by one or a plurality of stabilization bearings can.
  • a second body be provided, which with each of the detected by the first plant body Edges opposite edges of the plates should cooperate and one Having second sloping contact surface.
  • the two contact surfaces of the plant body are essentially parallel to each other.
  • the immovable second contact body a contact surface, the one on the corresponding side surface of the Stack corresponds to overhanging staggered alignment of the edges of the plates.
  • this system body also has a vertical stop surface the plates in the stack that are not covered by the staggered orientation be retained in the staggered alignment movement.
  • the plates can be used one at a time sucked and preferably pulled away laterally, which is already known is.
  • the plates can be used one at a time sucked and preferably pulled away laterally, which is already known is.
  • the plates can also be pushed away by slides.
  • the slide with suction according to the above explanations be combined. But you can also without suction plates of push away the stack, which is also already known.
  • the operating stroke of the aligner can be smaller be as the power stroke of the transport device for separating the plates.
  • an inflator is also used to separate from each other Separate the plates to support.
  • the blowing device preferably blows against the front edges of the plates in relation to the direction of removal. These Edges are preferably offset by the corresponding alignment Stack side surface overhanging aligned, as the embodiment shows. By this overhanging arrangement is the separation effect of the already known Blowing particularly efficient.
  • the transport device for separating the plates can, for example, additionally to the mentioned sliders or suction means a pair of rollers or Belt, wherein the plates inserted between the rollers and / or belt and can be transported through a transport gap.
  • the roller / belt pair ensures further transport, for example a roller conveyor or a similar conveyor track.
  • the figure shows a schematic side view of a device according to the invention.
  • first contact body 2 Left above the stack is a first contact body 2 with an oblique contact surface 3 shown.
  • This plant body 2 is shown in the by the above Arrow symbolized way horizontally displaceable in the drawing plane. This takes place by a non-illustrated and conventional drive unit with a central pneumatic cylinder and two horizontally arranged next to it Linear bearings.
  • a second contact body 4 drawn with a second inclined contact surface 5, which is stationary.
  • On the second inclined contact surface 5 closes below a further vertical contact surface on, which is parallel to the adjacent side surface of the stack 1.
  • the designated 6 arrow on this second plant body 5 symbolizes a blowing device 6, the air under pressure against at the second oblique contact surface 5 can align adjoining plate edges.
  • the second system body 4 with the contact surface 5 and the blowing device 6 are perpendicular along the plane of the drawing standing plate edges arranged side by side, which is not shown in detail is. Specifically, the plant body 4 is in two parts and are not on the smaller parts of the plate edges limited bodies 4 covered parts of the Plate edges large area detected by the blowing device 6.
  • Stack 1 Above the upper left corner of stack 1 and substantially centered above it Stack 1 are two aggregates drawn with suction units, numbered 7 and 8 are. They each have only symbolically represented carriage with pneumatic Actuators 9 and 10 and also have with 11 and 12th designated arms, at the end of each row 13 or two staggered rows 14 and 15 are mounted with suction units.
  • the pneumatic actuators 9 and 10 are not only movable in the horizontal direction of the drawing plane, but the arms 11 and 12 can also be perpendicular to the plane of the drawing Tilt axles.
  • a further arm 16 is also articulated to the end of a slider 17 is attached.
  • a pair of rollers 18, 19 is arranged, the between the rollers 18 and 19 on the lower edge of the top plate 20 of the stack 1 is aligned.
  • the upper roller 18 is also mounted vertically elastic. This is in the figure based on the gripped in the transport gap top plate 20 of To recognize stacks 1.
  • the device shown works with very thin plates (not shown here) as follows: After delivery of a new batch 1, the plates are first in it not precisely aligned, so that the stack 1 in the middle vertical side surfaces having. The uppermost plates, in this case the top six plates, of the stack 1 are moved into the detectable by the contact surface 3 area. By a horizontal movement of the plant body 2 (in the figure to the right) pushes the contact surface 3, the top six plates as shown in the figure to the right, this at its opposite end in contact with the second Contact surface 5 of the second contact body 4 come. It represents the vertical Contact surface of the second body 4 sure that by excessive adhesion between the plates not accidentally moved further, lower plates with become.
  • the suction device 7 engages with the suction units 13 the top plate and pulls it back a little, so in the figure to the left. Of the rear side edge of the uppermost in the sense of this movement Plate, so the right side edge in the figure, thereby a strip of the underlying Plate exposed. Then the suction device 8 moves the two Suction cups 14 and 15 to this edge of the top plate and sucks the top Plate in the figure to the left of the edge and the underlying plate in the figure right of the edge with the respective Sauger Horn 14 (for the top plate) and 15 (for the underlying plate). Both suction devices 7 and 8 can then bring the plates up to the pair of rollers 18, 19, so that their respective right Edge between the rollers 18 and 19 is used.
  • the pair of rollers 18 and 19 are not continuous across the adjacent edge of the plates is executed. Rather, it is two pairs of rollers distributed along this edge, between which the suction device 8 can be moved. Thereby the two uppermost plates between the pair of rollers 18, 19 are gripped, so that they can be pulled away laterally, for example, on a roller conveyor to get.
  • the symbolized by the arrow blowing device 6 blows continuously Air against the overhanging in the region of the second contact surface 5 edges the plates, making them easier to remove from underlying plates when removing can be separated.
  • the device shown in the figure for different plate types is usable, with the plates either sucked individually and laterally can be taken away or sucked in pairs and together as a couple can be transported away laterally or finally at heavier single Plates without suction individually or in the majority removed via a slide can be.
  • the pair of rollers 18, 19 is used. While the topmost layer or the top two layers of the stack 1 side are transported away, the stack 1 by the corresponding height upwards crazy, whereupon the plant body 2 and 4 with a new clock again for the staggered positioning worry. This positioning takes place after each acceptance process of plates.
  • the example illustrates the various advantages of the staggered arrangement the top plates of the stack 1. On the one hand, they are detached from each other, if the edges or surfaces of the plates should have previously glued together. Second, as in a conventional vertical orientation, a defined Plate position produced, so that the teat rows 13, 14, 15 attack accurate position can and in particular the slide 17 is no long creeper (to avoid a collision with the edge). Finally, the effect of the blowing device 6 due to the fouling in the adjacent area of the plate stack 1 improved.
