Definitions

  • the present invention relates to a device for adjusting the height of building blocks and the like as defined in the preamble of claim 1.
  • Document FR-A-2 440 258 describes and represents such a device which can, in certain cases, have the drawback of requiring a particular adaptation of the press cycles for the production of the blocks, by the fact that the blocks must be move discontinuously through this device.
  • the present invention aims to provide a device of the above type which can easily adapt to all known presses for the manufacture of building blocks.
  • the leveling cylinder is mounted on a chassis movable in height with respect to the blocks to be adjusted, between a high position, in which the cylinder is in an inactive state, and a low position.
  • the cylinder can accomplish the aforementioned flattening, the spacing or guide members being fixed relative to this frame and cooperating with the upper face of a plate or board carrying said blocks when the cylinder is in its low position, the distance separating the leveling cylinder from the part of the spacer or guide member intended to cooperate with the plate or board carrying the blocks to be adjusted being, in this low position, substantially equal to the total height predetermined blocks.
  • the spacing and guide members comprise wheels or rollers mounted at a fixed distance relative to the leveling cylinder and moving on the upper surface of the plate or board carrying the blocks to be adjusted, when the above-mentioned element is in its low position.
  • the invention relates essentially to the manufacture of concrete blocks and especially of light concrete blocks, for example based on expanded clay, having at least one hollow passing right through the blocks over the entire height and which can be assembled dry. so as to form downward channels into which a binder, in particular concrete, can be poured.
  • a quantity of material is deposited on the upper faces of the blocks, which can harden and become fixed on the latter, preferably a product based on cement and in particular pure cement, of a height which is greater than the difference between a predetermined height. or prescribed and the actual height of the block in question, and to flatten, at least partially, this material on said faces before hardening thereof until the total height of said block corresponds substantially to the predetermined or prescribed height, this total height being formed by the sum of the actual height of said block and that of this amount of flattened material.
  • This material is deposited on the blocks as soon as they leave the press, that is to say before they are dry, so that this material can harden and become fixed to said blocks, at least partially under the effect of the humidity in the blocks themselves.
  • blocks are formed in a mold, by means of a static press, the height of which is lower, for example by 1 to 2 mm, than this predetermined height.
  • a quantity for example in the form of a heap of the above-mentioned material, in particular powdery cement, the height of which is greater than the difference in height between the predetermined height and the actual height of the block in question.
  • this quantity of material is flattened, in particular by means of a roller or cylinder, until the total height of said blocks, formed by the sum of its actual height and that of the quantity of material , corresponds substantially to the predetermined height.
  • the blocks thus adjusted in height are subjected to drying and hardening.
  • the blocks move in a substantially continuous manner at the outlet of the press and preferably as well during the deposition of the piles of material on the upper surface of the blocks as during the flattening of these piles.
  • These blocks are in particular formed in the static press on platens, called boards, which, at the exit of the press, move on a conveyor formed of two parallel endless chains animated by a continuous movement.
  • the device according to the invention has the advantage that it does not slow down the production of blocks in the static press, the operations of deposition of the material on the blocks and the flattening operation of this material preferably being carried out without interrupting the advancement of the plates carrying the blocks which come out of the press.
  • the aforementioned flattening is advantageously achieved by means of a cylinder which rolls, without sliding, above the blocks, at the aforementioned predetermined height.
  • the appended figure schematically shows a particular embodiment of a device making it possible to apply the method described above.
  • This device essentially comprises a metering device 1 for depositing on the upper faces of blocks 2 a quantity of a material in the form of cones 3 and an equalizing device 4 for flattening these cones on the blocks so as to give the blocks a total height. substantially corresponding to the aforementioned predetermined or prescribed height.
  • This device is mounted at the outlet of a static press, not shown, for the manufacture of concrete blocks.
  • the metering device 1 and the equalizing device 4 are mounted in series on the same rigid frame 5 so as to form a one-piece assembly.
  • the metering device comprises a hopper 6 with an inclined bottom 7 distilled to contain the powdery product, in particular the cement, to be deposited on the blocks.
  • This hopper has at its lowest part a series of holes 8 each cooperating with a separate closure member 9 for adjusting the amount of product passing through each of these holes.
  • This metering device 1 is preceded by a cylindrical brush 10 suspended from the frame 5 at a height adjustable by screw rods 11.
  • the equalizing device 4 comprises a leveling element above a space 12 in which the blocks 2 can be brought to flatten the cones 3, deposited on the blocks by the hopper 6 of the dosing device 1.
  • spacers or guide members 13 are provided to maintain the leveling element, at a distance from the underside of the blocks corresponding substantially to the aforementioned predetermined height during the flattening of the material deposited on the blocks. .
  • This leveling element comprises, in the embodiment shown in the figure, three identical cylinders 14 whose axes extend in the same substantially horizontal plane. These cylinders are actuated around their axes, so that each point of their cylindrical surface generates a cycloidal curve relative to the blocks, that is to say rolls, without sliding on the material on the latter.
  • the equalizing device 4 also comprises a sliding frame 15 suspended, by means of screws 16 controlled by handwheels with handle 17, from a frame of the frame 5.
  • the cylinders 14 are in turn mounted in a chassis 19 which can undergo a downward and upward movement, as indicated by the arrows 20, relative to the frame 15, between an upper position, in which the cylinders are in a state inactive, and a low position, in which the cylinders can accomplish the abovementioned flattening operation.
  • the spacing or guide members 13 are fixed relative to the chassis 19 carrying the cylinders 14 and cooperate with the plate or the board 22 carrying the blocks 2 to be adjusted when the cylinders are in their low position, that is that is, near the top surface of the blocks. This is the position shown in the figure.
  • the spacing and guiding members comprise wheels or rollers 23 mounted on the lower end of a vertical section 24 welded to the chassis 19.
  • These wheels or rollers 23 are, in the figure, two in number per cylinder 14 and extend on either side of the vertical plane of symmetry passing through the axis of a cylinder.
  • Means are provided for adjusting the distance between the cylinders and the wheels or rollers.
  • these means consist of machined shims 25 which can be placed between the lower end of the profile 24 and bearings 26 fixed on the latter and carrying the rotation shaft of the wheels or rollers 23 .
  • Such means could, for example, be used to adapt the distance separating the cylinders 14, in their low position, from the boards 22 with which the rollers or wheels 23 cooperate in this position.
  • the wheels or rollers 23 rotate freely about their axis in the bearings 26, while the cylinders 14 are driven by means of a geared motor 27 controlled by an incorporated frequency converter. This drive takes place by means of toothed belts 28 moving around pinions 29 mounted on the rotation shaft of the different cylinders 14.
  • This drive is such that when the cylinders are in their low position, they can roll on the blocks 2 without sliding, that is to say so that each point of the cylindrical surface of the cylinders 14 generates a cycloidal curve.
  • This conveyor belt 30, preferably formed by two parallel endless chains, is moving in the direction of the arrow 31 in a continuous manner, first drives the blocks under the brush 10, which removes from the upper surface 32 of the blocks ba essential part of the burrs.
  • the blocks pass automatically and continuously below the openings 8 of the hopper 6 of the metering device 1 and cone-shaped cement blocks 3 are deposited at very precise locations on the upper surface 32 blocks.
  • the board 22 then passes, still in a substantially continuous manner, into the space 12 of the equalizing device 4.
  • the frame 19 carrying the cylinders 14 is subjected to a downward movement by means of the jacks 21 up to when the wheels or rollers 23 meet the board and roll freely on the latter, this descent being for example of the order of 0.5 to 1 cm.
  • a blowing device 34 is provided on the frame 5 at the entrance to the space 12 to sweep this raceway.
  • the mobile frame 15 carries not only the chassis 19 but also the hopper 6.
  • rollers for example squeegees, not shown, acting on the cylindrical surfaces of the rolls when the latter are in the high position, that is to say their position not active.
  • the spacing and guiding members could be replaced by a double conveyor belt between which are taken the longitudinal edges of the boards 22 at the time of their passage in the space 12 and in which the boards are kept at a constant distance from fixed supports against which the frame 19 can abut in its lowest position, so as to be located at the aforementioned predetermined distance allowing the height of the blocks to be adjusted 2. It would suffice, for example to provide a lower conveyor belt which makes it possible to apply the board against an upper conveyor belt moving in guide rails or else a raceway above the two longitudinal edges of the boards.
  • Yet another variant consists in using a leveling element fixed in height, but comprising rollers undergoing translation in the direction of movement of the blocks, however providing for means of transport separate from the conveyor 30, the latter moving in a manner substantially continuous, which can temporarily release the boards of this conveyor 30 to maintain them for a short period of time in a stationary position at a well-determined distance, corresponding to the aforementioned prescribed height, from the cylinders 14 at the moment when the latter flatten the cones 3.
  • a momentary stop could also be provided in the metering device.
  • the aforementioned adjustment method is not necessarily limited to hollow blocks intended to be filled with concrete or any other binder, but can be applied to any type of hollow block or not, which can preferably be placed dry on top of each other in a wall construction.
