Definitions

  • the invention relates to an apparatus for manufacturing green bricks for the production of bricks, comprising a conveyor movable in stepwise manner for carrying mould containers separated into compartments by dividing walls, supply means for supplying pieces of clay to the mould containers, means for simultaneously forming groups of pieces of clay and simultaneously feeding a group to the supply means.
  • the apparatus according to the invention is further characterized in that the discharge point of the sub-groups is displaceable in the direction transversely of the transporting direction of the conveyor for the mould containers.
  • the operation of the different means and the conveyors is preferably synchronized such that after each displacement stroke of the conveyor for the mould containers the discharge point is displaced.
  • the discharge point is displaceable between two end positions, and between the end positions is displaced one step at a time over the distance between two compartments and, after performing the penultimate step, is displaced through a step which has the dimension of the width of one compartment in order to reach the end position.
  • the discharge points of the sub-groups are mutually shifted over a fixed distance.
  • the supply means consist of a plurality of conveyor belts connecting to each other in series, wherein for the different groups the last conveyor belt in a series has a length differing from the last in another group.
  • each group of conveyor belts is displaceable relative to the conveyor for mould containers together with the feed means for groups of pieces of clay on the series of conveyor belts.
  • the apparatus comprises a frame 1, inside which a conveyor 2 is displaceable in the direction of arrow P. Conveyor 2 is driven stepwise. As seen in lengthwise direction the conveyor carries a plurality of mould containers 3 sub-divided by dividing walls into compartments, in this embodiment 18.
  • the apparatus further comprises a plurality of, in this case two, series of nine sub-devices respectively 4, 5 placed one behind the other for forming pieces of clay.
  • a strand of clay is formed from a supply holder 6 and cut to length at the bottom, whereafter the formed strand piece falls onto a first conveyor belt 8 of a successive series of conveyor belts.
  • the series of conveyor belts 8, 9, 10, 11, 12, 13 connect to each other in a cascade, wherein the formed pieces of clay fall from the one conveyor belt onto the other and are herein covered with sand on all sides.
  • each of the sub-groups 14, 15, 16 a different length is chosen for each of the sub-groups 14, 15, 16.
  • a conveyor belt pair respectively 17, 18 and 19 for the purpose of accelerating the fall of a piece of clay such that it is carried with comparatively great force into one of the compartments of the mould containers 3.
  • the sub-groups 14, 15 and 16 are displaced in their entirety, i.e. the series of conveyor belts with the supply means 6, 7, in a direction transversely of the transporting direction of conveyor 2. In this manner the discharge point of the supply means is displaced over a part of the width of the conveyor. Due to the shifted character of the discharge point of the different sub-groups 14, 15 and 16 the whole width of the conveyor is thus covered.
  • Fig. 2a-2k show successively the manner of filling the compartments.
  • the discharge point between the end positions corresponding with mould container 1 and 6 for sub-group 14, respectively 7 and 12 for sub-group 15 and 13 and 18 for sub-group 16 is displaced two steps at a time, while at the end position one step is carried out.
  • a step is then taken by the conveyor (fig. 2b) such that thereafter compartments 5 and 6 of the following three mould containers are filled.
  • the same pattern applies for the other sub-groups 14 and 16.
  • the pattern according to fig. 3 finally results, wherein after a number of cycles a mould container is completely filled. All compartments of all mould containers are then filled on the conveyor. Attention is drawn to the fact that the progression of fig. 2a-2k applies only during initial operation of the apparatus.
