Definitions

  • the invention generally relates to a press for molding concrete products, such as concrete blocks or the like, which in particular comprises an improved device for feeding concrete for molding these products.
  • Such presses for molding concrete products are well known in the prior art, and they generally comprise a vibrating table, a mold movable selectively in height by means of jacks, to be placed on the vibrating table and to be filled with concrete, a tamper, compacting the concrete in the mold and allowing the release of the products by lifting the mold, and a concrete feed device comprising a hopper associated with a filling drawer driven back and forth under the hopper for filling the mold.
  • This filling drawer used in the prior art poses a number of problems and is inconvenient to use. Indeed, the slide movement control cylinders are subjected to hydraulic reactions called water hammer during the use of the drawer, and the hydraulic control circuits suffer from it and see their life reduced. There are also sealing problems on the periphery of the drawer, relatively rapid wear of the drawer and the upper face of the mold, transmission of mechanical shocks producing significant noise, an obligation to frequently clean this filling drawer. It is also necessary, when changing the mold and using a mold of different height, to adjust the height position of the drawer correspondingly.
  • the object of the present invention is to avoid all these drawbacks, and for this it proposes a press for molding concrete products, comprising a vibrating table, a mold intended to be placed on the vibrating table and to be filled with concrete, a means for supplying concrete, such as a hopper, and means provided between this hopper and the mold for filling the latter with a predetermined quantity of concrete, characterized in that the means for filling the mold comprise a belt conveyor endless, disposed under the hopper and comprising means for driving the belt in a predetermined direction, and means for moving the conveyor as a whole in reciprocating rectilinear motion to pass the front end of the conveyor over the mold and bring it back to an initial position.
  • the conveyor is arranged at a fixed height in the press.
  • this press also comprises means for recycling the excess concrete after scraping from above the upper edge of the mold, and from the endless belt.
  • these recycling means comprise a chute for receiving concrete scrapings, and means, such as a worm, for bringing the scrapes collected in the chute towards the endless belt of the conveyor, in an area located immediately before the concrete feed hopper, so that the recycled concrete deposited on the strip is covered by the concrete coming from the feed hopper during the next mold filling cycle.
  • the vibrating conveyor corridor has two lateral guide walls and has a decreasing width in the direction of movement of the concrete scrapings, width which is maximum at its end adjacent to the mold and minimum at its end adjacent to the conveyor belt.
  • the conveyor belt is constituted by a first endless belt on which the concrete scrapings freely fall at the exit of the vibrating conveyor corridor, and by a second endless strip which then overlaps the first endless strip to trap the concrete scrapings during their transport to the endless strip of the mold filling conveyor located at a higher level of the press than the vibrating conveyor corridor.
  • the press which has been shown very diagrammatically in FIG. 1, comprises in known manner a vibrating table 10, which supports a wooden board 11 or any suitable material intended to receive the molded concrete product.
  • a mold 12 In the molding position, a mold 12 is lowered, by means of hydraulic jacks not shown, onto the board 11. At its upper part, the mold 12 comprises a flange 13 having the shape shown in the drawings.
  • a tamper 14 movable in vertical reciprocating rectilinear movement by means of hydraulic cylinders 15.
  • the tamper 14 In the mold filling position, the tamper 14 is raised above the mold, and also above the means for filling the concrete mold, which will be described in the following.
  • the concrete press feed means include a hopper 16, fixedly mounted on the chassis and intended to contain a certain amount of concrete.
  • the conveyor 17 With the hopper 16, there is provided a conveyor 17 with an endless belt 18.
  • the conveyor 17 essentially comprises a frame 19, carrying at its rear end a driving roller 20 for moving the endless belt, and at its front end a roller 21 mounted mad on which the strip 18 passes. It is understood that the rollers 20 and 21 make it possible to advance the upper strand of the endless strip 18 in the direction indicated by the arrow 22.
  • the chassis 19 of the conveyor 17 also includes, for example on its rear lower part, a rack 23 fixedly mounted on the chassis, and with which meshes a motor pinion 24 driven by any suitable means not shown.
  • the pinion system 24 - rack 23 makes it possible to move the conveyor 17 as a whole in reciprocating rectilinear movement in the two directions indicated by the arrows 25.
  • the conveyor In the position shown in solid lines in Figure 1, the conveyor is in its rear position, while in the position shown in dotted lines, it is in its most advanced position, an intermediate position being shown in phantom line.
  • the frame 19 of the conveyor 17 also supports two lateral guide walls 26 which extend longitudinally relative to the frame on either side of the upper strand of the endless belt 18 and which serve to delimit the width of the layer of concrete deposited by the hopper 16 on the upper part of the endless belt 18.
  • These lateral guide walls 26 also carry at their end a squeegee 27, which is intended to scrape the lower surface of the tamper 14, to clean it, when the latter is in the high position shown in the drawing.
  • a register 28 is also provided above the conveyor belt 18, for example being fixed on the front side of the hopper 16, to adjust the thickness of the concrete layer deposited on the belt 18.
  • the quantity of concrete which will be poured by the endless belt 18 into the mold 12 is determined on the one hand in lateral dimension and in height by the side walls 26 and by the register 28, and in longitudinal dimension by the speed of movement of the endless belt 18 around the rollers 20 and 21, and by the speed of movement of the conveyor 17 driven by the motor pinion 24 meshing with the rack 23.
  • the press shown in FIG. 1 also comprises means for cleaning the endless belt 18, and means for scraping the upper part 13 of the mold 12.
  • the means for cleaning the endless belt 18 include a squeegee 30, provided under the front roller 21, mounted at the end of a lever 31 articulated at an intermediate point on the chassis 19 and provided for example with a counterweight at its end free.
  • the scraping means of the upper edge 13 of the mold 12 comprise a squeegee 32 supported by a frame or arms 33.
  • the frame 33 and the squeegee 32 are moved in horizontal rectilinear movement by means of a jack 34 carried by the chassis of the machine, and pivoting in a vertical plane by means of a lifting cylinder 35.
  • the squeegee 32 and the frame 33 have been shown in their extreme front position. They can be brought back from the mold by means of the jack 34.
  • the jack 35 makes it possible to raise the squeegee 34 in its advancing movement, and then descends to let it rest on the edge 13 of the mold, during its return movement on the side of the cylinder 34.
  • the lifting cylinder 35 also makes it possible to adjust the height position of the squeegee 32, to adapt it to the different heights of mold used.
  • Such a device further comprises a chute 36 for receiving the concrete scrapings brought back by the squeegee 32, and also concrete scrapings removed from the endless strip 18 by the scraper 30. These concrete scrapings are guided in the trough 36 by an inclined plane 37.
  • the chute 36 is associated with means for recycling concrete scrapings, which for example comprise an endless screw, housed in a tubular housing 38 disposed obliquely between the chute 36 and the conveyor 17.
  • the chute 36 communicates with the lower part of the tube 38 by a conduit 39, while the upper part of the tube 38 is provided with a discharge conduit 40 making it possible to deposit the concrete scrapings brought back to the top of the tube 38 by the screw without end on the endless belt 18, immediately before the location of the hopper 16.
  • the concrete scrapings collected and deposited on the endless belt 18 are covered with fresh concrete coming from the hopper 16, during the following cycle filling a mold.
  • This arrangement allows an intimate mixture of fresh concrete and concrete scrapings, which would not necessarily be obtained if the concrete scrapings were brought directly into the hopper 160
  • the recycling device 100 consists of a vibrating conveyor corridor 101 and a conveyor belt 102 with endless belts.
  • the vibrating conveyor corridor 101 is constituted by a plate 103 of elongated shape bordered laterally by two guide walls 104. On each of the lateral sides of this conveyor corridor 101 is provided a vibrating device 105 known per se.
  • the end 106 of the plate extends over a width corresponding at least to the width of the mold 12, while its other end 107 extends over a lesser width corresponding substantially to the width of the conveyor belt 102.
  • the two lateral guide walls 104 of the plate are inclined relative to the longitudinal axis of this plate and arranged symmetrically relative to this axis.
  • This conveyor passage 101 is mounted in the press at an intermediate level between the level where the vibrating table 10 is located and the level where the conveyor 17 is located, by being mounted in an inclined plane with its widest end 106 located at a lower level relative to the level of its other end 107. More precisely, the end 106 of the plate 103 must be located at a level below the level reached by the upper surface of the smallest mold 12 capable of being used, to be sure that the scraped concrete falls in all cases, by gravity, on the plate 103. This end 106 of the plate 103 is adjacent or near immediate of the side wall of the mold 12 perpendicular to the conveyor 17 and adjacent to the latter when it is in its rear position shown in FIG. 1.
  • This particular arrangement of the conveyor corridor 101 is mainly due to the presence of the conveyor 108 which ensures the transport of the boards 11 to the vibrating table 10, conveyor 108 which is mounted parallel to the conveyor 17. Under these conditions, the vibrating conveyor corridor 101 is mounted in the space delimited by the two conveyors 17 and 108.
  • the conveyor belt 102 consists of two endless belts 110, 111.
  • the endless belt 111 is wound between two end rollers respectively lower 112 and upper 113. With respect to the rear position of the conveyor 17 as shown in FIG. 1, the rollers 112 and 113 are situated respectively below and above the conveyor 17.
  • the roller 112 is situated slightly beyond the roller 20 of the conveyor 17, in a direction opposite to the direction 22 of movement of the conveyor 17, while the roller 113 is located between the roller 20 of the conveyor 17 and the hopper 16.
  • the endless belt 111 passes over an intermediate roller 114 situated slightly above the conveyor 17 to allow the belt 111 to bypass the conveyor 17 when the latter is in its rear position.
  • the endless belt 111 passes over a succession of intermediate rollers 115 arranged substantially in an arc of a circle.
  • the endless strip 110 is wound between two end rollers respectively lower 116 and upper 117.
  • the roller 116 is located below the end 107 of the vibrating conveyor passage 101, so that the strip 110 receives scrapings of falling concrete by this end 107 of the vibrating conveyor passage 101.
  • the roller 117 is located above the roller 113 of the endless belt 111, between the auxiliary roller 114 and the upper roller 113 associated with the belt. without end 111.
  • the belt without end 110 passes from roller 116 to roller 117 by resting on roller 112 and the intermediate rollers 115 of the endless belt 111. Then the endless belt 110 is brought back from roller 117 to roller 116 by means of two auxiliary rollers 118, 119.
  • the two endless belts 110 and 111 respectively exterior and interior, are in contact with one another on a common path delimited by the roller 112, the intermediate rollers es 115 and the roller 117.
  • the axes of all the aforementioned rollers are mutually parallel and perpendicular to the direction of movement of the conveyor 17.
  • the surface of the endless strip 110 intended to receive the concrete scrapings may have successive cells or compartments 120 to ensure better transport of the concrete scrapings.
  • the press described operates as follows: when the conveyor 17 is in the position shown in solid lines in the drawings, and a mold 12 is lowered onto the vibrating table 10 while being pressed on the board 11, the tamper 14 being in the raised position shown in FIG. 1, it suffices to control the drive of the endless belt 18 in the direction indicated by the arrow 22 and to control the movement of the conveyor 17, by means of the pinion 24 and the rack 23, to advancing it into its extreme front position shown in dotted lines in FIG. 1.
  • the drive of the endless belt 18 in the direction of arrow 22 causes the concrete to spill over the entire surface of the mold, during the movement of the conveyor 17, as shown diagrammatically in FIG. 1.
  • the filling of the mold can be carried out either during the forward movement and the return movement of the conveyor 17, or only during the forward movement of the conveyor 17
  • the speed of movement of the endless belt 18 can be constant, or continuously variable, if desired. It is understood that the speed of the endless belt 18 and the speed of movement of the conveyor 17 are adjusted so that, when the endless belt 18 is stopped, and therefore the pouring of the concrete into the mold 12 is stopped, this is filled with a slight surplus of concrete.
  • the squeegee 32 When the filling of the mold is finished, the squeegee 32 is moved forward, above the mold, but without being in contact with it, by the cylinder 34, then by means of the cylinder 35, the descent of the squeegee 32 is controlled on the edge 13 of the mold, and the squeegee is returned to its rear position by means of the cylinder 34.
  • the scraped concrete then falls into the chute 36 , with the concrete which has been scraped off on the endless strip 18 by the scraper 30, and it is recycled by being brought back onto the endless strip 18 in the aforementioned manner by means of the endless screw housed in the tube 38.
  • the tamper 14 is lowered onto the mold 12, on the one hand to put the concrete at a constant height in the mold 12, and on the other hand to allow the molded product to be removed from the mold when the mold 12 is raised.
  • the tamper 14 is finally raised and returned to its initial position shown, after which the board 11 carrying the molded product is removed and replaced by a new board 11.
  • the continuous recycling device according to the second embodiment operates as follows ( Figures 3, 4).
  • the squeegee 32 which cooperates with the upper edge 13 of the mold, brings back the scraped concrete by dropping it on the vibrating conveyor passage 101 near its end 106 adjacent to the mold 12.
  • the vibrators 105 subject the vibrating corridor 101 to appropriate vibrations so as to transport the concrete scrapings from the end 106 to the end 107 of the corridor, the concrete scrapings going up the inclined plane formed by the plate 103 of the conveyor corridor 101. Then, the scrapings freely fall onto the endless belt 110 of the conveyor belt 102.
  • the endless belt 111 is superimposed on the belt 110 to trap the concrete scrapings and allow their transport to a higher level of the press in order to bring them back onto the endless belt 18 of the conveyor 17.
  • the concrete scraped by the scraper 30 associated with the endless belt 18 of the conveyor 17 is also continuously recycled by the same path, these scrapings falling directly onto the vibrating conveyor corridor 101.
