Definitions

  • the invention relates to a device for manufacturing bricks from clay, with means for carrying clay from a supply holder into mould containers, means for covering the clay with sand, means for filling up the mould containers, means for transporting and turning over mould containers and means for releasing the brick from a mould container.
  • the phenomenon can herein occur that portions of clay adhere fixedly to the side walls.
  • the invention has for its object to provide an improvement for this drawback. This is achieved according to the invention in that the means for releasing a brick are formed by porous openings in the walls of the mould container and means for generating air pressure on the outer walls of the mould container.
  • the mould container is manufactured from a sinter plastic material.
  • a sinter plastic material to this end use can be made of the commercially available material Fitroplast®.
  • the desired air pressure can be obtained by placing the mould container into a space connectable to an air pressure line.
  • the invention is elucidated with reference to an embodiment.
  • Fig. 1 shows schematically the manner of moulding a brick using mould containers.
  • Fig. 2 shows in perspective view an elucidation of the method of release according to the invention.
  • an endless conveyor 2 which carries a number of mould containers, for instance 3.
  • the mould containers are filled by the throwing device 4 with a block of clay 5 covered with sand.
  • Sand-covering takes place using the sand-covering device 6.
  • the clay comes from a supply holder 7 from which pieces of clay are discharged at the outlet 8 thereof using the discharge means 9.
  • a topping-up member 11 Placed at another outlet 10 of supply holder 7 is a topping-up member 11 which tops up the mould containers.
  • a carrying plate 13 is placed on the mould container. After the turning point 14 of conveyor 2 the mould container is released and the brick falls with the carrying plate onto a discharge conveyor 15.
  • mould containers are used (fig. 2) of porous material, for instance sinter plastic material.
  • a suitable material is Fitroplast®.
