Definitions

  • AAC blocks are poured into molds and after reaching them the green stability.
  • the still plastic one (green) aerated concrete block which is about 6 - 7.5 m long, a width of about 2m and a height of about 65 - 75 cm has, is brought to a cutting machine and there by means of tensioned steel wires cut lengthways and crossways, so that cuboid porous concrete blocks, blocks or plates are created. These are then placed in an autoclave steam pressure hardened.
  • cutting the still plastic AAC block is about 3 - 12 cm at the top thick layer separated, which are removed before hardening got to.
  • this waste layer is a layer at an uneven height when driving the aerated concrete mass arises.
  • aerated concrete blocks are also made according to the DE-C-958 639 tilted 90 ° after demoulding, so that it then stand on their long narrow side and in this position can be cut more precisely.
  • After cutting the aerated concrete block is then placed in the autoclave preferably again by 90 ° to its largest broadside tilted (see DE-A-21 08 300).
  • a known device for removing the pruning the top of plastic aerated concrete blocks or the like Waste layer (DE-B 1 683 837) has one of above the block lowerable suction box on the has numerous perforations on its underside. Below these openings is a cover device provided in the form of a flexible film that is jalousie-like can be pulled over part of the openings to cover these. In this way, the device for Lifting off different sized waste layers can be used.
  • the previously known device is expensive to manufacture and in operation. Since she works with vacuum and at Aspiration of the waste layer of dust and aerated concrete particles get into the suction air, are filters for dusting them Air necessary, which must be cleaned regularly.
  • the invention has for its object a device to remove the when cutting plastic aerated concrete blocks, especially upright aerated concrete blocks or the like to create the resulting upper waste layer, which is inexpensive to manufacture, low operating costs caused and also has a long life.
  • the invention is therefore based on the idea of the waste layer by means of a variety of nails made by two opposite sides diagonally from top to bottom be stabbed into the waste layer and then by means of the support frame can be lifted synchronously, purely mechanically, i.e. without suction air, to capture and up from that lift off the remaining aerated concrete block. Since no one here Dust and aerated concrete particles are contaminated, any air filter and its maintenance can be omitted.
  • the device itself consists of relatively simple ones mechanical components and only requires a proportionate low drive power, making them inexpensive is manufacturable and only minor in operation Operating costs caused.
  • the nails once they are in the waste layer are stabbed by the weight of the same and the weight of the moving parts of the device in "Gripping position" held so that when suddenly interrupted the energy supply, e.g. in the event of a power failure, the layer of waste caught by the nails cannot fall.
  • the device according to the invention is part of a Cutting machine to cut one on its long one Narrow side of standing aerated concrete block.
  • the Device is above the in this cutting machine long upper narrow side of the cellular concrete block and has one in a frame, not shown lifting and lowering crossbar 1, which is parallel to long narrow side of the cellular concrete block extends.
  • Below the traverse 1 are on this several pairs P of Support frame 2, 2 'arranged.
  • the mounting rails are in mutual distance a from each other according to the type of Tines of a rake are arranged, facing each other facing longitudinal sides 2a, 2'a of each pair of frames P overhang.
  • the Support rails 3 of the first support frame 2 in the gaps between the support rails 3 'of the second support frame 2' one and vice versa.
  • This C-profile is from the front each mounting rail 3, 3 'forth one example an aluminum alloy existing nail bar 4 can be inserted.
  • the Nails 5 of the first support frame 2 are in one acute angle ⁇ of about 25-35 °, preferably 30 °, inclined with respect to the longitudinal median plane M. All nails 5, which are assigned to the first support frame 2 parallel to each other and are at the same angle ⁇ inclined with respect to the longitudinal median plane.
  • the first supporting frame 2 is in direction B, which is parallel to the longitudinal direction of the nails 5 runs relative to the crossbar 1 slidable.
  • the nails 5 'of the second support frame 2' are arranged in the same way in nail strips, which are inserted into the mounting rails 3 ', all nails associated with the second support frame 2 ' are arranged parallel to each other, but in one acute angle ⁇ 1, which is opposite to the acute angle ⁇ is inclined with respect to the longitudinal median plane M.
  • the Angle ⁇ 1 can be the same size as the angle ⁇ .
  • a Angle of 25-35 °, preferably 30 °, has surprisingly been found proven to be particularly advantageous since this the greatest holding forces in the relatively soft, plastic Aerated concrete can be achieved and the least risk there is a breakout of this aerated concrete.
  • the second Support frame 2 ' is in the longitudinal direction of its nails 5' in Movable in direction C relative to the crossbar 1.
  • the nails 5, 5 ' which advantageously have a length of about 200 mm and a diameter of 2.5 - 5 mm, preferably about 3 mm, are inclined from above Bores 7 of the nail strips 4 inserted so that their Tips are pointed down and their heads in a depression is located at the top of the nail bar.
  • the heads of the nails can touch each other support the inside of the mounting rail 3 and are thus kept safe. Should it break or bend of a nail, the associated nail bar can 4 slightly pulled out of the mounting rail 3 and the damaged nail can be replaced with a new one.
  • each mounting rail 3 has on its one End a spring clip 8 on the front opening the mounting rail 3 partially covered, and on their other End a stationary tab 9, which acts as a stop for the Nail bar is used.
  • each guide rod 10, 10 ' is a correspondingly inclined guide bush on the crossbar 1 11, 11 'provided in which the associated Guide rod 10, 10 'is displaceable.
  • a common servomotor 13 is provided on the traverse side, which is designed as a stepper motor.
  • the servomotor 13 drives via an angular gear 14 and several shaft pieces 15 an actuating gear 16 for each support frame 2 or 2 ' on.
  • the actuating gear 16 contains an angular gear driven spindle nut which is parallel to one the threaded rods 17 running the guide rods 10 or 10 ' surrounds.
  • Waste layers have different thicknesses.
  • FIG 2 is a waste layer with a dash-dotted line A indicated with the greatest expected thickness D.
  • the thickness of the waste layer is due to the sloping Side wall of the mold over the width of the waste layer increasingly in the embodiment shown.
  • the sheet metal plate 18 is essentially arranged horizontally, including a slight one here Understand inclination to the horizontal the angle of inclination relative to the horizontal the angle of inclination of the mold side walls with respect to the vertical corresponds.
  • a foam rubber plate 20 is provided at the bottom of the sheet metal plate 18 .
  • the plate 18 with the foam rubber plate 20 serves primarily to Support the aerated concrete block during cross cutting. The cross cutting is done by having several in one frame tensioned wires by moving the frame from bottom to bottom be moved up through the aerated concrete block.
  • the foam rubber sheet 20 needs no breakthroughs because it is used by the pointed nails 5, 5 'simply pierced. If the nails 5, 5 'when lifting the support frame 2, 2' upwards from the Foam rubber plate 20 are pulled out, then the Foam rubber plate 20 together with the sheet metal plate 18 as Scraper, any adhering to the nails 5, 5 ' Remains of aerated concrete. Since the stripped remains located on the underside of the foam rubber sheet 20, fall just down them.
  • the new device works as follows:
  • the plastic aerated concrete block standing on its long narrow side is first cut in by horizontal cutting wires Cut lengthwise, with one at the top Place an upper waste layer in place of the cutting wire is separated.
  • the traverse 1 is located on it arranged support frame 2, 2 'and the sheet metal plate 18 in their upper position so that the movement of the slitter is not hindered. After slitting has been completed the traverse 1 is lowered vertically, wherein the support frame 2, 2 'in that shown in Figure 1 Release position. Lowering the traverse 1 takes place until the foam rubber plate 20 on the upper Narrow side of the cellular concrete block is in contact. Then it happens the cross cutting from the bottom up until the cutting wires rest on the foam rubber sheet 20.
  • the still plastic one AAC mass of the waste layer is known as Fresh waste of the aerated concrete mass of another batch mixed in.
