Definitions

  • the present invention relates to a machine for manufacturing molded products, in particular concrete, of the type comprising a molding assembly mounted to pivot around a horizontal axis, this assembly comprising at least one mold and a counterweight; means for pivoting the molding assembly between a horizontal loading position in which the mold is turned upwards and a horizontal unloading position in which the mold is turned down; means for holding, during the pivoting of the molding assembly, a mold release plate against the product contained in the mold; and means for receiving the release plate with the product molded thereon, these means being located under the molding assembly when the latter is in its unloading position.
  • the patent FR-A-579 442 describes a machine of this type in which the products are stacked at their exit from the mold of the molding assembly.
  • this machine has a complex structure which makes it expensive both for purchase and for maintenance.
  • the presence of the stacking device if it allows it to satisfy manufacturers manufacturing products in large series, forces those who limit themselves to multipurpose manufacturing and short series to make excessively high investments for a machine that is used below its possibilities.
  • the present invention proposes to remedy these drawbacks and, to do this, it relates to a machine of the aforementioned type which is essentially characterized in that the receiving means are provided for lowering and depositing the release plate on the anterior section an evacuation route, on the path of ejection means which can be moved alternately along said front section under the control of the counterweight to which they are connected by a mechanical junction, the ejection means being downstream of the front section of the evacuation route when the molding assembly is in its loading position and upstream of said anterior section when the molding assembly is in its unloading position.
  • This machine has a space-saving structure and can be installed in an already existing manufacturing workshop. Its movements are also continuous and linked, which allows high production rates. It is also suitable for versatile manufacturing and small series, the molds it uses can be installed quickly and with a limited number of settings. Finally, its purchase and maintenance cost is low, so that small and medium-sized enterprises can acquire it without significantly disrupting their financial situation.
  • the evacuation path is formed by horizontal beams extending perpendicular to the pivot axis of the molding assembly, these beams carrying rollers on their upper face and delimiting between them a space large enough to allow passage to the counterweight during the pivoting of the molding assembly.
  • the receiving means consist of two horizontal knives carried by vertical supports passing between the side members of the anterior section of the evacuation route, these knives delimiting between them a sufficiently large space to allow passage to the counterweight during the pivoting of the molding assembly and being vertically movable, when it is in its unloading position, from a high position in which they are in contact with the release plate to a low position in which they are at a lower height to that of the rollers of the anterior section of the escape route.
  • the ejection means are constituted by two tabs provided at the rear end of two arms movable parallel to the evacuation route and delimiting between them a space large enough to allow passage to the counterweight during the pivoting of the assembly molding, the two tabs having a height greater than that of the rollers of the anterior section of the evacuation route.
  • the machine which can be seen in the drawings is designed for the production of reinforced or unreinforced concrete molded products and is more particularly intended for the manufacture of elements for fences such as posts and plates. It comprises a frame consisting essentially of vertical uprights 1 a, 1 b, 1 c arranged in two rows pa rallying and facing two by two.
  • the uprights 1b are situated substantially at equal distance from the uprights 1a and 1c and are provided at their upper part with bearings (not shown) on which the ends of a horizontal shaft 2 are connected, connected in a manner known in itself to the output shaft of an electric or other motor intended to rotate it alternately 180 ° in each direction.
  • the shaft 2 is fixed along one of the side faces of a molding assembly 3 and allows it to pivot between a loading position (visible in Figure 1) in which it rests on the uprights 1a and an unloading position (visible in Figures 3 and 4) in which it is completely turned over and rests on the uprights 1c.
  • the molding assembly comprises a mold 4 fixed on a vibrating plate 5 carrying a vibrator 6 on its underside, this plate resting on a chassis 7 by means of silent-blocks 8.
  • the molding assembly When the molding assembly is in its loading position, it extends horizontally and rests on the uprights 1a which are connected at their upper part by crosspieces not visible in the drawings for the clarity thereof. Its mold 4 is then turned upwards and is located below a concrete hopper 10 provided with a retractable hatch 11 closing off its outlet 12.
  • the molding assembly When the molding assembly is in its unloading position, it still extends horizontally but is supported on the uprights 1 by means of two other ears 13 projecting from the longitudinal faces of its vibrating plate 5. In this case, its mold is turned downwards and overhangs the anterior section of an evacuation route 14 which will be described below.
  • the molding assembly On its lateral face which is bordered by the shaft 2, the molding assembly carries a support 15 at the free end of which is fixed an elongate counterweight 16. This is perpendicular to the support 15 which is itself perpendicular to the aforementioned lateral face of the molding assembly.
  • the support 15 serves as a base for two parallel plates 17 on which the small branch of an L-shaped arm 18 is articulated, the articulation axis 19 of this branch being parallel to the shaft 2 and slightly higher than that last when the molding assembly is in its loading position.
  • the small branch of the arm 18 is articulated on the rod 20 of a jack 21 whose cylinder 22 is articulated in turn on a yoke fixed to the upper end of the counterweight.
  • the arm 18 can thus pivot around the axis 19 between an active position (shown in solid lines in FIG. 1) in which its large branch projects above the molding assembly , parallel to the mold 4, and an inactive position (shown in dashed lines in FIG. 1) in which its large branch is brought back above the support 15.
  • the large branch of the arm 18 carries on its face turned towards the molding assembly, studs 23 ending in rubber pads 24 intended to come to bear against a release plate 25 which is placement on the mold after pouring the concrete but before pivoting of the molding assembly towards its unloading position.
  • the evacuation path 14 is essentially constituted by four horizontal beams 26a, 26b, 26c, 26d carrying rollers 27 on their upper face. These beams, which are perpendicular to the shaft 2 and situated at the same height, are formed here by U-shaped profiles whose branches are turned towards the longitudinal axis of the track 14.
  • the machine comprises two horizontal knives 28 carried by vertical supports 29 slidably mounted in guide sleeves 30 fixed on the side members 26a and 26d.
  • the supports 29 are connected at their lower end by a connecting bar 31 which is articulated on a connecting rod 32 pivotally mounted about an axis 33 provided on one of the uprights 1c. They are also vertically movable under the control of a jack 34 coupled to the connecting rod 32. Under the action of this jack, they can thus move alternately between a high position (visible in Figures 1, 3 and 5) in which they are likely to come into contact with the plate 25 when the molding assembly 3 is in its unloading position, and a low position (visible in FIG. 4) in which they are at a height lower than that of rollers 27 .
  • the machine according to the invention also comprises ejection means 35 intended to push along the track 14 the plates 25 on which the molded products rest. These means can be moved parallel to the track 14, between an advanced position (visible in FIG. 1) in which they are downstream from the anterior section of the track 14 when the molding assembly 3 is in its loading position, and a retracted position (visible in Figures 3 and 4) in which they are upstream of said section when the molding assembly is in its unloading position.
  • the ejection means consist of two braced arms 36 forming a carriage provided with rolling rollers 37 cooperating with the wings of the side members 26b and 26c and a rear cleat 38 rising at above the rollers 27 of the track 14. These arms are each articulated on a bent connecting arm 39 itself articulated at the upper part of the counterweight 16. It is easily understood that the two connecting arms 39 allow the arms 36 to be alternately move along the front section of the track 14 during the pivoting of the molding assembly between its loading and unloading positions.
  • the hatch 11 of the concrete hopper is opened in order to pour into the mold 4 the quantity of concrete necessary for the production of a product to be produced.
  • This quantity can be determined automatically by means of a conventional dosing device.
  • the product to be manufactured must include a frame, this is of course placed in the mold before the hatch 11 opens.
  • the vibrator 6 is then actuated in order to distribute the concrete uniformly in the mold and to avoid the formation of internal defects in the molded product.
  • a timer can be provided to control the shutdown of the vibrator.
  • the actuator 21 is then actuated so that the arm 18 comes into its active position and firmly holds the plate 25 against the mold 4.
  • the motor which is engaged with the shaft 2 is now actuated so that the molding assembly 3 comes into its unloading position visible in FIG. 3.
  • the counterweight 16 comes between the uprights 1b and 1a while the ejection means move from their advanced position visible in FIG. 1 to their retracted position visible in FIG. 3.
  • the jack 21 is actuated in order to move the arm 18 away from the board 25 as well as the jack 34 to lower the knives 28.
  • the motor which is engaged with the shaft 2 is now actuated in the opposite direction, which allows the molding assembly to return to its loading position and the tabs 38 to push the plate 25 on which the molded product rests, slightly downstream of the uprights 1 tsp.
  • the ejection means 35 reach their advanced position before the counterweight 16 returns between the uprights 1b and 1c. The risks of the board 25 being struck by the counterweight are therefore completely avoided.
  • actuator 34 is actuated to return the knives 28 to their high position.
  • the machine is therefore ready to describe another operating cycle during which a new product can be produced.
