Definitions

  • the present invention relates to a machine for manufacturing molded products, in particular concrete.
  • the present invention proposes to remedy these drawbacks and, to do this, it relates to a machine which is characterized in that it comprises on the same frame: a molding assembly comprising at least one mold; means for pivoting the molding assembly between a loading position in which the mold is turned upwards and an unloading position in which the mold is turned downwards; means for holding, during the pivoting of the molding assembly, a mold release plate against the product contained in the mold; an evacuation route, the front section of which is in the zone situated under the molding assembly when the latter is in the unloading position; means for lowering the demolding plate with the molded product and depositing it on the discharge path, these means coming into action when the molding assembly is in its unloading position; and, ejection means for pushing the plate along the evacuation path, these means being movable parallel to the evacuation path, between an advanced position in which they are downstream of the anterior section of the evacuation path evacuation when the molding assembly is in its loading position and a retracted position in which they are upstream of said anterior section when the molding assembly is
  • This machine has a space-saving structure and can therefore 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 businesses can acquire it without significantly disrupting their financial situation.
  • the molding assembly is pivotally mounted around an axis along one of its lateral faces. It thus suffices it to a li- b e limited space for movement between its positions of loading and unloading. It is also closely associated with the evacuation route, which makes it possible to produce the machine with a compact and space-saving structure.
  • the molding assembly extends horizontally when it is in its loading and unloading positions, which are located on either side of its pivot axis and offset by 180 ° relative to the other..
  • the filling of where the molds can thus be carried out automatically, for example from a hopper situated above the molding assembly when the latter is in the loading position. Similarly, demolding can be carried out at its turn automatically since the molding assembly is completely returned when it is in its unloading position.
  • the molding assembly comprises a counterweight mounted at the free end of a support fixed on its lateral face which is bordered by its pivot axis, this counterweight having an elongated body and extending perpendicular to said pivot axis.
  • the counterweight facilitates pivoting of the molding assembly and that it allows the use of means which, to control this pivoting, can be of low power. Energy consumption can therefore be reduced significantly.
  • the means for holding the release plate are moreover constituted by an arm articulated on the support of the counterweight, and by a jack for moving the arm between an active position in which it presses against the plate and an inactive position in which it is distant from the plate, the jack bearing on the counterweight.
  • the evacuation route it consists of longitudinal members supporting rollers, these longitudinal members extending perpendicular to the pivot axis of the molding assembly and providing between them a sufficiently wide interval to allow passage to the counterweight during pivoting of the molding assembly.
  • the means for lowering the demolding plate consist of two horizontal knives carried by vertically displaceable supports, these knives being situated in planes parallel to those of the longitudinal members of the evacuation route and being movable between a high position in which they are in contact with the plate when the molding assembly is in its unloading position and a low position in which they are at a height lower than that of the rollers.
  • the ejection means are constituted by two parallel arms which can be moved alternately along the anterior section of the evacuation route and carrying at their rear end a cleat rising above the rollers.
  • the tabs can come to bear against the upstream transverse side of the release plate in order to drive the latter along the track d 'evacuation.
  • the two arms are provided with rollers resting on guide rails parallel to the longitudinal members and providing between them a sufficiently wide interval.
  • these two arms being articulated each in the vicinity of their cleat on a link arm itself articulated on the counterweight.
  • the control of the ejection means which is here provided by means of the counterweight, is therefore always synchronized with the pivoting of the molding assembly.
  • the machine that can be seen in the drawings is designed for the production of molded reinforced concrete products or not 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 1a, 1b, 1c arranged in two parallel rows and facing two by two.
  • the uprights 1b are located substantially equidistant 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 in a manner known per se 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 the latter to pivot between a loading position (visible in FIG. 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 sake of 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 rests on the uprights 1c by means of two other lugs 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 side face of the molding assembly.
  • the support 15 serves as a base for two parallel plates 17 on which is articulated the small branch of an L-shaped arm 18, the axis of articulation tion 19 of this branch being parallel to the shaft 2 and slightly higher than the latter 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 rest against a demoulding plate 25 which is put in place on the mold after pouring the concrete but before the molding assembly pivots 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 beams 26b and 26c provide between them a central space large enough to allow passage to the counterweight 16 when the molding assembly pivots between its loading and unloading positions.
  • 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 the rollers 27.
  • the machine according to the invention also includes 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 dans.sa unloading position.
  • the ejection means consist of two braced arms 36 forming a carriage provided with rollers 37 cooperating with the wings of the side members 26b and 26c and a rear cleat 38 rising above the rollers 27 of the track 14. These arms are each articulated on a bent link arm 39 itself articulated at the upper part of the counterweight 16..We can easily imagine that the two link arms 39 allow the arms 36 to move alternately 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 reinforcement, 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 jack 21 is actuated so as to move the arm 18 from the board 25 as well as the jack 34 to lower the knives 28.
  • 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.
