Definitions

  • the invention relates to a device for producing bossed split stones from rectangular concrete blanks.
  • the concrete blanks from which such split stones are made consist of highly compressed concrete, preferably filled with free-flowing natural stone material. These blanks are first split in a central plane and gap or fracture surfaces arise that have unevenness. While these bumps in the central area of the split surface are desirable, on the one hand as a slip protection for paving or made of ornamental greens, these bumps along the edges of the split surfaces are not desirable because the split stones with their split surface outwards in the association then have steps along their edges . All four edges of each gap surface are therefore chiselled to a uniform height. This process is called bossing.
  • the object of the invention is to design a device of the type mentioned in such a way that, with simple device and operating effort, embossed split stones can be produced uniformly in one pass.
  • the invention is characterized by claim 1.
  • Each of the two bossers is designed such that it bosses the two gap surface edges which are laterally opposite one another in the conveyor row. Since there is a right-angled change of direction between the two bossers, all four edges are bossed after passing through the second bosser.
  • the finished embossed split stones are packed in stacks, generally on pallets.
  • the weight of many stones weighs on the lowest stones. It is desirable not to burden the embossed surfaces with this weight. This is taken into account by further training which is the subject of claim 2.
  • the split stones are then accepted and packaged with a vertical split surface. The split surfaces can therefore not be loaded by the stone load lying above them and, moreover, this also ensures that the split stones with cast, smooth surfaces stand on one another, which is advantageous for the stability of the stack.
  • the splitter can be designed to split horizontally or vertically. It is preferably designed to split horizontally. Then the two split stones split from a concrete blank lie on top of each other, namely the lower one with the split surface up and the upper one with the split surface down. If the split stones with the same orientation, namely with the split surface up, are to enter the bosser, one of the two split stones of one blank must be turned into the orientation of the other. This is particularly easy to do with the horizontal splitting plane. This takes advantage of a training that is the subject of claims 4 and 5.
  • the split stones In order to achieve a straight edge at a predetermined height when bossing, the split stones must be reproducibly and precisely guided along the chisels. This is hindered if the split stones move undesirably when bossing, possibly under the influence of the chisel that oscillates on the edges.
  • a heavy mass of the individual rollers which is approximately 0.3 to 3 times, preferably 2 times, the weight of a split stone is sufficient for the desired effect.
  • a feed conveyor 1 is arranged downstream of a splitter conveyor 3 equipped with a splitter 2 at right angles.
  • a separator conveyor 95 with a separator 23 is arranged downstream of this splitter conveyor 3 the separator 23 is followed by a bossing conveyor 6 equipped with a first bosser 4.
  • a second bossing conveyor 7 is arranged at right angles to this bossing conveyor 6 and is equipped with a second bossing conveyor 8.
  • a removal conveyor 11, which is equipped with a tipper 10 is arranged downstream of the second bossing conveyor 7.
  • a packing table 12 equipped with a packing conveyor 58 is connected at right angles to the removal conveyor 11.
  • the conveying surfaces of all conveyors are arranged horizontally in a common plane and meet without gaps.
  • the conveying surface of the feed conveyor 1 is formed by the rear surfaces 32 of a plurality of endlessly rotating V-belts 33 to 37 facing away from the wedge surfaces 30, 31 (FIG. 4).
  • the conveying surface of the splitter conveyor 3 is a sliding surface.
  • the singling conveyor 95 consists of a conveyor belt, which serves as a buffer after the singling device 23.
  • the bossing conveyor 6 consists of a conveyor belt upstream of the conveyor, which is followed by a sliding surface which extends over the area of the conveyor 4. This sliding surface is followed by a conveyor belt.
  • the bossing conveyor 7 consists of a sliding surface which extends over the area of the bossing device 8 and which is followed by a conveyor belt following the bossing device 8, which extends into the area of the tipper 10.
  • the removal conveyor 11 consists of a sliding surface
  • the packing conveyor 58 consists of a sliding surface.
  • the feed stamp 88 is assigned to the sliding surface of the feed conveyor 1.
  • the feed ram 45 is assigned to the sliding surfaces of the feed conveyor 1 and the splitting conveyor 3.
  • the feed ram 47 is assigned to the sliding surface of the bossing conveyor 7.
  • the feed stamp 142 shown in FIG. 9 is the sliding surface of the Removal conveyor 11 assigned and the feed stamp 14 is assigned to the sliding surface of the pack conveyor 58. The feed rams and the conveyor belts are driven so that the blanks or split stones are fed in the direction of arrow 89.
  • the feed conveyor 1 is operated from a stock of concrete blanks, not shown, via a gripper 38, which can be a robot or an operator.
  • the blanks (FIG. 3A) or stones are indicated by small squares in FIG. 1 and it can be seen that on the feed conveyor 1 the concrete blanks 50 are conveyed in groups of four blanks in a row in a row. The foremost group of four is pushed by the feed ram 45 on the splitter conveyor 3 in the direction of arrow 41 and forms there with other groups a series of individual blanks, which come in groups between the knives 51, 52 of the splitter 2 in advance by pushing each other forward.
  • the knife 51 is brought into oscillation by an assigned drive unit 53 with a horizontal splitting plane, while the knife 52 is rigidly directed against it in a support unit 54 on the same horizontal splitting plane.
  • the knives split the blanks in this group in the horizontal central plane.
  • Each blank now forms a pair of two split stones (Figure 3B).
  • This split stone pair 55 still reaches the separator 23 under the feed effect of the feed stamp 45.
  • the separator conveyor 95 is operated in a clocked manner.
  • the separator 23 includes a sliding surface 195, a feed ram 60, a stationary lock 57 and a spring-loaded return device 196.
  • the sliding surface 195 is arranged next to the separating conveyor 95.
  • the retractor 196 grasps the split stones at the top when the feed stamp 60 is advanced and tilts them when the feed stamp 60 returns, on the sliding surface 195, the split stones tilting over the lock 57 and rotating by 180 degrees, so that the split surfaces of all split stones now point upwards . ( Figure 3C)
  • the singling conveyor 95 carries out a conveying cycle and removes the group of split stones previously located below.
  • the feed punch 60 pushes the tilted split stones onto the singling conveyor 95 in the row of the split stones already there and the singling conveyor 95 carries out a new feed cycle and also promotes this split stone group.
  • the feed stamp 60 now withdraws and there is room for the next group of split stone pairs.
  • split stones 70 which are individually lined up one behind the other and which are arranged with their split surface 71, 67 facing upwards (FIG. 3D). These stones pass on the bossing conveyor 6 into the effective area of the bosser 4, which extends from both sides to the respective side Longitudinal edges of the split surface acts on these split stones and bosses them. Above 1 to 5 mm (millimeters) of height is removed from above along the relevant edges, on a horizontal level that is uniform for all stones.
  • the row of split stones is aligned by side, endless, umlau fender belts 68, 69, which extend through the bosser and support the split stones there during the bossing process and slide them over the sliding surface of the bossing conveyor.
  • the split stones then reach the tipper 10, in which they are all tilted transversely to the conveying direction by an angle of 90 degrees, so that the split surfaces point to the right in relation to the viewing direction of the viewer from FIG. 1 (FIG. 3F).
  • the five foremost split stones are gripped by the stamp 14 and pushed onto a pallet (not shown) or another packing material on the packing table 12.
  • the packing table 12 is adjustable in height. If the first layer of the split stones is formed on the packing table 12, then this is lowered by a stone height and the next stones are pushed onto the already formed stone layer to the second stone layer, then the packing table is lowered again and so on.
  • the split stones which are stacked in several layers, are tied into bundles.
  • the splitter 2 and the bossers 4 and 8 can be set up to different dimensions of the cuboid concrete blanks.
  • the feed stamps 45 and 60 are also on their group sizes or to a different length of the knives 51, 52 can be set up or adjusted.
  • These devices and adjustments can be remotely controlled via a control unit 80 with a control unit 81 for the feed rams, an adjustment unit 82 for the two bossers 4 and 8 and an adjustment unit 83 for the splitter 2.
  • the arrows 84 indicate corresponding control lines, while the handles 85 serve for setting and operation.
  • sensors for the split stones are attached, for example the sensor 73 for the feed stamp 14, which activates the feed stamp 14 when a row of split stones is available in the effective range of the feed stamp 14.
  • the knives 51, 52 of the splitter 2 are made in several parts.
  • several chisels stand side by side and with their cutting edges form the continuous cutting edge of a knife.
  • the individual chisels resiliently support each other on balls which are guided in a zigzag-shaped channel, so that the chisels can yield to one another to a small extent.
  • Both knives can be adjusted to adapt to the stone width. However, it is also sufficient to make only one knife adjustable. In such a case, however, the subordinate bosser must be made adjustable on the same side to adapt to the stone width, so that the newly set bosser stays in line with the splitter.
  • the split stones as can be seen for split stone 106 from FIG. 7, point upwards with their rough, uneven split surface 123 and extend with them two opposite side edges 109, 110, which are to be bossed, in the conveying direction according to arrow 102.
  • the cutting edges 111, 112 of two chisels 113, 114 are set on a straight horizontal line just below these edges 109 and 110 and the corresponding edges of the other split stones.
  • the chisels 113, 114 are arranged on opposite sides of the split stones 104 to 108 and are mirror-symmetrical with respect to each other and at the same height, relative to the conveying direction according to arrow 102, to the mirror-symmetry plane indicated by the dash-dotted line 115.
  • the chisels are driven in an oscillating manner along their axes 116, 117 according to double arrow 118, 119 by drive units 120, 121, which are only indicated in FIG. 7.
  • the axes along which these chisels act extend at an acute angle 122, 124 upwards.
  • two massive rollers 125, 126 are arranged opposite each other mirror-symmetrically to the mirror-symmetry plane 115, which are rotatably mounted in bearings 129 to 132 fixed to the housing about roller axes 127, 128.
  • the axes of rotation 127, 128 extend perpendicular to the axes 116 and 117, respectively, of the chisel located on the same side, and are therefore inclined by the amount of the acute angle 124 with respect to the vertical.
  • the peripheral surfaces 133, 134 which come into contact with the side surfaces of the split stones, are beveled with respect to the axis of rotation in the form of a truncated cone in accordance with the inclination of the axis of rotation of the associated roller.
  • the split stones are guided in the interest of exact guidance between the runs 140 to 143 of the endless belts 86, 87 arranged in pairs, which are designed as V-belts. These belts 86, 87 are driven at the conveying speed of the bossing conveyor 6 in the conveying direction according to arrow 102 and the drawn runs rest on both sides of the split stones and are optionally supported on the back by slide rails, not shown, in order to form a good guide for the split stones.
  • rollers 125, 126 In order to use the available space below the chisel for the desired high mass of the rollers 125, 126, they extend with their axial height to at least the upper run 140, 143 and have a recess 144, 145 for this circumference.
  • the side surfaces 135, 136 are not always exact and so that the rollers can carry out corresponding compensatory movements, they are movably mounted in the direction of the double arrows 118, 119 or perpendicular to the side surfaces 135, 136 and in the opposite direction.
  • Return springs 146 to 149 act on the bearings of the rollers and press the rollers 125, 126 against the associated side surfaces 135, 136.
  • the chisels 113 and 114 can be adjusted in height to different heights of the side edges 109, 110 and in terms of the angle of attack according to the acute angle 124.
  • rollers 125, 126 adjustable in height in order to always adjust the rollers at different heights of the chisel so that their circumferential surfaces 133, 134 extend right up to the edges 109, 110 to be bossed. If, due to a further lowering of the rollers, the recesses 144, 145 no longer offer sufficient space for the strand 140, 143, then this strand is removed in the region of the rollers and, if appropriate, also the strand 141, 142. This is not necessary for the entire route to dispense with the pressure tapes, you then insert two pressure tapes on each side in the conveying direction one after the other, which leave a corresponding recess for the roll between them.
  • the chisels are preferably flexible in the direction of the double arrows 118, 119 against a restoring force element (not shown) so that they can adapt to any unevenness and small tolerance differences in the stone width.
  • the split stones reach the tipper 10 on a conveyor belt 15 of the bossing conveyor 7. At the end of this conveyor belt, the split stones fall with a simultaneous rotation by approximately 90 degrees onto a catch plate 92, which is arranged at the free end of a catch arm 94 movably mounted about the axis 93 .
  • the catch arm 94 is equipped with a counterweight 97 and is relieved in its swiveled-up position, in which the catch plate 92 is in the position shown in broken lines in FIG. Loaded by a split stone, the catch arm 94 gives way against the force of its counterweight 97 to the position shown in the solid line in FIG. 9 with the catch plate 92 approximately at the level of the sliding surface of the removal conveyor 11.
  • the split stone is then in alignment with the feed stamp 42, which is the series of Split stones in the direction of the arrow 89 stone by stone.
  • the Catch arm 94 serves to dampen the falling of the split stones from the conveyor belt 15 onto the take-off conveyor 11.
  • a finished embossed split stone is now described with reference to FIGS. 10 to 13, which reaches the removal conveyor 11.
  • the split stone described is a paving stone according to the selected dimensions. Other dimensions are also possible; accordingly, such split stones are designed or usable as facing stones, masonry stones, facing stones and the like.
  • 201 is a paving stone made of high-density concrete, which has the basic shape of a cuboid.
  • the concrete is filled with free-flowing natural stone material.
  • the dimensions for the surface length according to double arrow 202, the surface width according to double arrow 203 and the depth according to double arrow 204 result from the table below, in which further dimensions are also given.
  • the side surfaces 205, 206, 207, 208 and the bottom surface 209 are smooth, flat surfaces which have been formed by molding on smooth, flat surfaces and which are perpendicular to one another.
  • the surface 210 is a fracture surface which was created by splitting the paving stone 201 from an approximately twice as large concrete blank and was then bossed, that is to say finely chiselled, along the edges 221, 222, 223, 224.
  • the highest points of the roughness 228 of the surface 210 are only a few millimeters according to the double arrow 214 above a central plane 215 which extends plane-parallel to the bottom surface 209.
  • the lowest points of the roughness 228, for example the invisible and only Points 216 and 217 shown in dashed lines are a few millimeters according to double arrow 218 below the central plane 215.
  • the roughness 228 extends between the upper limit 225 and the lower limit 226 over a depth indicated by the double arrow 229.
  • the bossing along the edges 221, 222, 223, 224 takes place on a common bossing plane 230, which extends plane-parallel to the central plane 215 approximately at the height of the lower limit 226, which coincides with this in the drawing.
  • the bossing creates straight edges along the four edges, which merge into the roughness 228 with an increasing slope 227, 232, 233, 234.
