Definitions

  • This invention relates to the manufacture of bricks, and more particularly to the formation of the frog in the larger face of bricks.
  • Bricks are conventionally manufactured by (a) pressing the raw clay into the required shape in individual moulds, or (b) extruding a column or slug of raw clay, which is subsequently wirecut into individual bricks.
  • Frogs can be formed in pressed bricks simultaneously with the initial pressing step, or at a subsequent repressing step. Extruded bicks cannot be provided with frogs during the extrusion process, however the slug can be extruded with holes extending throughout its length.
  • the slug is wirecut, bricks are produced with holes extending from bed-face to bed-face, such holes providing a similar keying action for the mortar as does a frog.
  • Pressed brick manufacture requires a large number of individual moulds, thus requiring expensive handling machinery * to obtain a desirable rate of production. It is the object of this invention to provide an apparatus for manufacturing bricks by the extrusion process and subsequently forming a frog in one bed-face of each extruded brick.
  • a method of manufacturing bricks comprising the steps of:- a) extruding a column of raw clay having at least a cross-section corresponding to the desired brick cross-section; b) conveying the column to a frog-forming station; and c) cutting a frog(s) out of at least one side of the column at a position corresponding to any face of each individual brick cut from, or to be cut from, the column.
  • the column is longitudinally cut into a plurality of slugs, and transversely cut to form a column of individually cut raw bricks.
  • apparatus for manufacturing bricks comprising means to extrude a column of at least one slug of raw clay of a desired brick cross-section, means to convey the column to a frog-forming station, means at the frog-forming station to form a frog in at least one side of the column at a position corresponding to any face of each individual brick cut from, or to be cut from, the column.
  • the frog-forming station comprises one or a plurality of frog cutters equal to a brick, or a number of bricks in the column.
  • the frog cutters each comprise rotating blades, which are arranged to gouge out a depression in the face of the brick.
  • the frog cutter may be mounted vertically or horizontally.
  • Figure 1 is a perspective view of one embodiment of the invention
  • Figure 2 is a cross-sectional view of part of the embodiment of Figure 1 .
  • Figure 3 is a perspective amalgam of a practical arrangement of the apparatus of this invention.
  • Figure 1 shows a column 10 of extruded clay intended to be formed into bricks.
  • Column 10 is cut longitudinally for example by a wire cutter (not shown) into four slugs 12 as the column 10 emerges from the extruder (not shown) .
  • Slugs 12 are then cut transversely at equal intervals to form individual bricks 11.
  • Slugs 12 are then moved by a conveyor (not shown) from the extruder to a frog-forming station 13 as shown in Figure 1.
  • Station B comprises two banks of frog-cutters 14,
  • Cutters 14- are arranged in two banks of two tiers, each cutter being fixed to a rotatable shaft 15.
  • Shafts 15 are rotatably carried by a carriage 16.
  • Carriage 16 is movable towards and away from column 10 along rails 24.
  • each cutter 14 comprises from blades 17 fixed to core 18 for example by bolts 19.
  • Core 18 is in turn fixed to shaft 15.
  • shafts 15 are rotatably interconnected by gear arrangement 20.
  • Lower shaft 15 carries a pulley 15a driven by drive means 21 via a belt 22. Rotation of the lower shaft 15 in the direction shown will cause the upper shaft, by means of gears 20, to rotate in the same direction with the same speed.
  • both shafts 15 can be provided at the same end with a pulley 15a, each driven by a drive belt from a double pulley mounted on the shaft of drive means 21.
  • Column 10 of individually cut bricks 11 is transported to frog-cutting station 13 by a conveyor (not shown) .
  • the conveyor is indexed to move column 10 in increments equal to the length of two bricks 11, corresponding to the number of banks of cutters 14.
  • Four banks of cutters will require movement of column 10 in increments of four brick lengths, and so on. Selection of the number of banks of cutters will depend on a number of factors such as the capacity of the extruder, and the capacity of the brick handling equipment downstream of the frog-cutting station 13.
  • drive means 21 is activated to rotate the cutters, and carriage 16 is gradually moved towards the column 10.
  • blades 17 engage each raw brick 12, they gouge out a depression or frog 23 in brick 12.
  • frogs are formed simultaneously in eight bricks, four on the side of the column 10 shown in Figure 1, and four on the other side. Obviously, four banks of two tiers of
  • cutters will enable simultaneous cutting of frogs 23 in 16 bricks.
  • Depth of the frog 23 is determined by the distance moved by carriage 16 towards column 10. On completion of the rog-cutting, carriage 16 is moved away from column 10, and column 10 is moved by the conveyor a further distance of 2 brick lengths.
  • FIG. 3 shows a practical arrangement of the apparatus of this invention.
  • the apparatus comprises two carriages 36 having wheels 41 so they are movable on rails 40 (only one of which is shown, the other rail being at the far end of the carriages) .
  • Each carriage has a gear rack 42 which engages with a pinion 43. Rotation of pinion 43 will simultaneously move both carriages 36 towards or away from each other, depending on the direction of rotation of pinion 43.
  • Each carriage 36 carries a plurality of rotatable frog-cutters 34; a total of forty-eight cutters arranged in four rows of twelve cutters, two rows on each carriaage.
  • Conveyor belt 44 carries the raw slug from the extruder to the frog-cutting station. Suitable control systems are provided to control starting and stopping of conveyor 44, movement of carriages 36 and operation of cutters 34.

Abstract

Procédé et appareillage pour fabriquer des briques en extrudant une colonne d'argile brute dont au moins une section transversale correspond à une section transversale désirée de la brique. La colonne extrudée est conduite à une station de formation d'incurvations comportant une pluralité de lames (34) rotatives servant à former les incurvations. Les lames rotatives sont montées sur des chariots (36) de chaque côté de la colonne d'argile. Les chariots sont avancés vers la colonne d'argile jusqu'à ce que les lames rotatives forment simultanément des incurvations d'une profondeur désirée dans une pluralité de briques coupées, ou qui seront coupées, dans la colonne d'argile brute.
