Definitions

  • the present invention relates to a machine for the continuous manufacture of flat elements obtained by compression of a pluvérulent mixture, machine of the type in which the pulverulent mixture is brought into molds arranged on an endless conveyor belt of which they are integral , said machine comprising a means for compressing the mixture placed in each mold cooperating with a counter-pressing means arranged on the other side of the mold.
  • Machines of this type are already known. They find an application for example for the manufacture of tiles, facing tiles for the building or other substantially flat elements.
  • the patent FR 2565155 describes an endless belt machine comprising molds fixed on a conveyor belt, which are presented successively at a compression station which is constituted by a press comprising two plates, one fixed the other mobile , actuated by a hydraulic cylinder with adjustable stroke.
  • US Pat. No. 1,469,819 describes a machine of the type of the previous one, in which molds are made to pass under rollers with a horizontal axis, all identical and whose axes are all in the same plane. However, there is no real compression in this machine, it is rather a forming of elements which then dry quickly.
  • this result is obtained with a machine for the continuous manufacture of flat elements obtained by compression of a pulverulent mixture, machine of the type in which the pulverulent mixture is brought into molds placed on a conveyor belt without end of which they are integral, said machine comprising a means for compressing the mixture placed in each mold cooperating with a counter-pressing means arranged on the other side of the mold, characterized in that the compression means consists of a set of pairs of successive rollers with horizontal axis, said rollers respectively forming an upper compression assembly and a lower abutment assembly relative to the path of the molds, the rollers forming the upper compression assembly being progressively offset from each other in the direction of movement molds to achieve progressive compression by rolling.
  • the machine according to the invention essentially comprises: - an endless conveyor belt (1) supporting molds (2); - a powder hopper (3); - a compression assembly (4); - Preferably a system (5) for demolding and taking up the molded parts.
  • the endless belt (1) is driven in a continuous movement between a control drum (6) and a tail drum (7).
  • the conveyor belt causes the molds to appear successively at each station of the machine.
  • the filling station the molds of course arrive empty.
  • the control can be carried out visually by the operator.
  • pulverulent material for example a mixture of sand, cement and various additives, coming from a peripheral kneading unit, not shown, by a conveyor (8) to the hopper.
  • the material is placed by a rotary distributor (9) and cut by an adjustable shell (10).
  • the shell contains a paddle shaft (11) which evacuates the surplus material and returns them to the hopper.
  • the molds therefore appear at the outlet of the hopper and of the shell with a certain height of material, of adjustable and desired thickness, point (12).
  • the molds then arrive at the compression assembly (4) consisting of a set of upper (13) and lower (14) rollers with horizontal axes, arranged in pairs.
  • rollers (14) are all identical to each other. Their axes are all located in the same plane parallel to the plane of the conveyor belt and therefore mold bottoms.
  • the upper rollers can be: - either identical and in this case their horizontal axis is gradually shifted downward to the vertical so as to decrease the free space between the tangency edges of a lower and upper roller of the same pair; - either different, with an equivalent function, the horizontal axes then remaining in the same plane.
  • FIG. 3 there is shown a pair of rollers (13,14) and a mold (2).
  • the mold (2) is caused to move in translation by the conveyor belt (1). It is positioned between the two rollers (13) and (14), which has the effect of slightly compressing the material contained in the mold.
  • the progressive adjustment of the compression from one pair of rollers to the next takes place by means of shims (15) arranged under the bearings (16) of the upper rollers (13).
  • rollers are rotated in opposite directions one relative to each other, as shown by the arrows in Figure 1.
  • the lower rollers (14) have fixed bearings (17).
  • each mold The six sides of each mold are determined as follows: - mold base including the external shape to be reproduced, - the two lateral sides parallel to the direction of travel consist of two fixed slides (18,19), - the back of each mold consists of a knife (20), see Figure 1, - the front of each mold consists of the knife (20 ′) of the previous mold, - the upper surface is formed by the upper compression rollers.
  • the element thus compressed which leaves the rollers (13,14) to the desired thickness and with the compression desired, is demolded at the level of the control drum (6) around which the conveyor belt is wound, molds loaded.
  • the compressed parts are then taken up by their smooth face by a second endless conveyor belt (21) moving at the same rate as the belt (1) comprising demoulding plates (22) which fit onto the molds of the belt ( 1) to take the pieces automatically continuously.
  • the device according to the invention finds a very wide application to multiple products.
  • the product obtained is very compact, the incompressibility threshold being easily reached.
  • This device is also less expensive both in terms of the design of the machine, its maintenance, its operation and therefore the products obtained.
  • the original feeding and cutting device at the level of the hopper can be very finely adjusted.
  • the invention finds a particularly interesting application in the field of products for the building and the house.
