Definitions

  • the mould container and/or movable bottom can be damaged by wear or when the movement of the bottom has a deviation or when hard portions in the clay become wedged between the peripheral edge of the bottom and the walls.
  • a further drawback of the known device is that when it is necessary to change brick form or brick size, the combination of mould container part and movable bottoms have to be changed.
  • Manufacture of a green brick of for instance larger dimensions requires the use of mould containers with larger mould cavities and accordingly larger movable bottoms. This is particularly a factor for relatively small differences in brick size because of shrinkage differences depending on the composition of the raw material used. All mould containers, including all movable bottoms, must also be changed in such cases, which is labour-intensive and moreover reduces the efficiency of the device as a result of the relatively long change-over time.
  • the present invention relates to a device for manufacturing green bricks from clay for the brick manufacturing industry comprising a circulating chain conveyor carrying mould containers combined to form mould container parts, means for arranging clay in the mould containers, one or more bottoms movable between the upright walls of the mould containers, one or more ejectors coupled to the movable bottoms for releasing the green bricks from the mould containers by displacing the bottoms, and means for discharging green bricks released from the mould according to the preamble of claim 1 containers.
  • the invention also relates to a mould container part suitable for manufacturing such green bricks and a method wherein such a mould container is used
  • Such a device is for instance known from the European patent 0 680 812 of applicant.
  • the known device is highly suitable for production of large numbers of green bricks for the brick manufacturing industry, wherein the green bricks are pressed out of the mould containers in efficient and certain manner by means of the movable bottoms.
  • BR-A-9 201 837 discloses a method for manufacturing green bricks from clay for the brick manufacturing industry, wherein clay is arranged in a deformable state in mould containers, after which it is transported. One or more green bricks of clay are released from one or more mould containers by displacing one or more bottoms movable between upright walls of the container.
  • the form and dimensions of the movable bottoms correspond in the known device of European patent 0 680 812 to those of the mould cavities in the mould containers.
  • a drawback here is that the peripheral edge of a movable bottom is subject to wear as a result of frequent sliding along the upright walls of the associated mould container. Furthermore, because the clearance between the movable bottom and the upright walls of the mould container is minimal, the mould container and/or movable bottom can be damaged by wear or when the movement of the bottom has a deviation or when hard portions in the clay become wedged between the peripheral edge of the bottom and the walls.
  • a further drawback of the known device is that when it is necessary to change brick form or brick size, the combination of mould container part and movable bottoms have to be changed.
  • Manufacture of a green brick of for instance larger dimensions requires the use of mould containers with larger mould cavities and accordingly larger movable bottoms. This is particularly a factor for relatively small differences in brick size because of shrinkage differences depending on the composition of the raw material used. All mould containers, including all movable bottoms, must also be changed in such cases, which is labour-intensive and moreover reduces the efficiency of the device as a result of the relatively long change-over time.
  • a mould container part for manufacturing green bricks from deformable clay for the brick manufacturing industry comprising:
  • a device for manufacturing green bricks from clay for the brick manufacturing industry comprising:
  • a pressing device for plate-like green bricks is described per se in the German document DE 19 27 560 U .
  • the document shows a mould with a movable bottom, wherein an intermediate space is provided between the edges of the movable bottom and the edges of the mould.
  • the pressing device is however a device for manufacturing green bricks of cured material such as concrete. The cured material is not deformable.
  • a mould container for manufacturing a concrete test piece is also known.
  • the mould container is provided with a bottom with a fixed part and a movable part.
  • the movable bottom part has dimensions such that an intermediate space is present between the area defined by the walls of the mould container and the peripheral edge of the movable bottom part. In its starting position the movable bottom part lies flush with the fixed bottom part.
  • the movable bottom part is used to press the concrete test piece out of the mould container when is it completely cured.
  • This document therefore also relates to manufacture of green bricks of cured concrete.
  • the manufacture of green bricks from deformable clay by first arranging the clay in mould containers of a circulating conveyor and subsequently removing the mould containers is not known herefrom.
  • said intermediate space preferably amounts to between 0.3 cm and 3 cm, and still more preferably to between 0.5 cm and 1.5 cm. At these values of the intermediate space it is possible to prevent the peripheral edge of the movable bottom coming into contact with the upright walls of the mould container, while the green brick of relatively soft clay, i.e. of relatively easily deformable clay, can nevertheless be removed in correct manner from the mould container.
  • the clay applied in the brick manufacturing industry with the described device and method for manufacturing green bricks from clay is relatively easily deformable.
  • the deformable clay has in such a case a deformability such that the remaining height measured in a plunger device according to the Pfefferkorn measuring method, as will be set forth below, amounts to about 9 mm or more.
  • the remaining height amounts in practice to less than 17 mm, since at higher values the clay has too little deformability.
  • the device or the mould container part is provided on one or more upright walls of a mould container with a fixed bottom part in order to at least partially fill the intermediate space.
  • a fixed bottom part and a movable bottom part wherein the fixed bottom part is provided on one or more of the upright walls of the mould container.
  • the fixed bottom part and the movable bottom are preferably situated practically at the same height, so that the clay in the mould container acquires a substantially smooth exterior.
  • the mould containers can be used to manufacture difference brick shapes and/or brick sizes with the same movable bottoms. If for instance after manufacture of a series of bricks a series of larger bricks must be manufactured, only the mould containers need exchanging for mould containers with a larger mould cavity and a wider fixed bottom part, while the movable bottoms can remain fitted.
  • a deformation can in some cases occur in similar manner as mentioned above.
  • the position of the deformation on the green brick differs however from the position of the deformation which can occur when the above stated known device is applied.
  • the deformation is situated some distance from the edges of the brick, which is perceived in most cases as less intrusive. The chance of rejection of the finally formed green brick is hereby relatively small.
  • a further preferred embodiment comprises a first fixed bottom part attached to a first wall and a second fixed bottom part which is attached to a second wall and which is less wide than the first bottom part.
  • the eventual choice of width of the fixed bottom parts depends on the form and dimensions, for instance the length-width ratio, of the green bricks to be manufactured.
  • the fixed bottom part is embodied to provide an open connection between the spaces on either side of the movable bottom. This has the purpose of reducing underpressure in the mould cavities during the ejecting movement of the movable bottoms. Underpressure can after all impede knock-out of the green bricks.
  • the movable bottom has dimensions such that the intermediate space is provided all around the movable bottom.
  • the fixed bottom part is preferably also arranged all around.
  • the fixed bottom part is provided with a chamfered side.
  • the chamfered side functions as positioning edge so as to facilitate assembly of the mould container parts.
  • a mould container part is coupled releasably to a chain part connectable to the chain conveyor.
  • the chain which is formed by the different, successively coupled chain parts, remains mounted on the conveyor.
  • the device 1 for manufacturing green bricks for the brick manufacturing industry comprises a chain conveyor 2. Placed on the chain conveyor is a large number of mould containers combined into units in the form of mould container parts 3.
  • the mould container parts 3 are coupled to each other and provided with rollers 15 rotatable over girders 14 ( figure 2 ) and thus together form the chain of chain conveyor 2.
  • the chain is driven by one of the chain wheels 13 or by both chain wheels 13 (wherein for the sake of clarity only the right-hand chain wheel is shown in figure 1 ).
  • the direction of transport of the chain conveyor is to the left (in figure 1 ) in the shown embodiment.
  • a conveyor rotating to the right is of course equally possible.
  • a reservoir 4 for clay which is kept in continuous movement by an agitator 5 which is driven by the electric motor 6.
  • Clay is supplied to reservoir 4 by a circulating conveyor 7.
  • the clay is carried out of reservoir 4 into the mould container and then pressed down by pressing device 8 which is pivotable about a shaft 9.
  • the excess clay is also trimmed using means which are not drawn.
  • the device 1 comprises a further conveyor 10 with which take-off plates 11 can be supplied. Conveyor 10 also ensures that a take-off plate 11 is placed on top of each passing mould container part 3. Take-off plates 11 remain pressed against the respective mould container parts 3 by a holding mechanism 12 when they pass over the left-hand chain wheel (not drawn). After turning over of the mould container part 3, the green bricks V still lie on plates 11. A knock-out mechanism to be further described presses the green bricks V out of the mould containers per mould container part. The green bricks V herein remain lying on plates 11 after they have been released from the mould containers.
  • a mould container part 3 consists of a mould container 16 which is provided with a row of mould cavities (in figures 1 , 2 and 3 respectively sixteen, fifteen and fifteen mould cavities ). Mould container 16 is mounted on bridge-like support elements 50,51 provided on the top side of a support plate 27. According to the first embodiment ( figures 2 and 3 ), support plate 27 is releasably mounted and according to another embodiment ( figures 6 and 7 ) is welded to or formed integrally with a chain part 17.
  • a chain part 17 consists of two support elements 22 which are provided with ears 18,19,20 and between which connecting elements 21 are arranged. Ears 18,19,20 function here as links of chain conveyor 2.
  • support plate 27 and chain part 17 are coupled to each other by providing support plate 27 with protrusions 25 and 25' which can engage on respective support elements 22 and additional support elements 26 of chain part 17. Using nut-bolt connection 23 and openings 33 the mould container part 3 and chain part 17 can then be fixed to each other.
  • each mould container 16 is provided with a displaceable bottom 29 (direction of displacement P3, figure 3 ).
  • the movement of displaceable bottoms 29 is driven by ejectors 24.
  • These are under bias of spring 30 which centres the ejector such that a separate guiding is not necessary in chain part 17.
  • Ejectors 24 are operated by a per se known drive device (not shown) during release of the green bricks.
  • the movable bottom is provided on the underside with a number of pins 68 of predetermined height, while the top side of support plate 27 is likewise provided with corresponding pins 67 of predetermined height.
  • both pins 67,68 determines the extreme position to which the movable bottom 29 can be displaced downward.
  • the lower pins 67 are provided on a displaceable strip.
  • the strip is herein provided with pins 67 of different heights, so that the displacement of the strip and the stroke of movable bottom 29 can be adjusted.
  • FIG. 4 shows a cross-section through a mould container 16 according to a first embodiment of the invention.
  • Mould container 16 comprises a fixed bottom part, while a separate movable-bottom 29 is provided in the mould container for sliding up and downward between the upright walls of the mould container.
  • Mould container 16 consists of at least one left-hand upright wall 41, a right-hand upright wall 40, a rear wall 42 and a front wall 43.
  • the mould container 16 is constructed from a left-hand and right-hand upright wall 41 and a number of successively placed rear and front walls 42,43.
  • Mould container 16 is preferably manufactured from plastic of relatively low weight, while the other components are made largely of steel. Although the rectangular form of the mould container and mould cavities shown here is the most usual, other forms are also possible. Cheeks 56, 57 are screwed fixedly to either side of the mould container in the embodiment shown in figures 2 and 3 . Mould container 16 can be fixed using cheeks 56,57 to respective support elements 50,51 by respective bolts 49. The mould container can be replaced by another mould container by unscrewing bolts 49, placing another mould container on support elements 50,51 and once again tightening bolts 49. Ejectors 24 and the associated structural parts remain coupled to the chain conveyor during the change. Change-over is thus less time-consuming since uncoupling and recoupling to the chain conveyor can be dispensed with.
  • each mould container 16 Further provided in plate 27 at the position of each mould container 16 is an opening 28 through which the ejector 24 of movable bottom 29 is provided.
  • the movable bottom can be displaced up and downward by ejector 24.
  • ejectors 24 press the movable bottom 29 downward from a starting position (i.e. direction P 3 in figure 4 ) so that the clay present in mould container 16 is pressed onto take-off plates 11. The thus released green brick of clay is then discharged with a discharge conveyor 52 ( figure 1 ).
  • a fixed bottom part in the form of respective strips 44,45 is arranged against the inner side of walls 40,41 of mould container 16, this such that in the starting position the fixed bottom part 44,45 forms, together with movable bottom 28, a practically closed bottom:
  • the top side of bottom 29 is moreover flush with the top side of the fixed bottom parts 44,45 in order to ensure a flat side of the green brick. In this situation there is minimal intermediate space between the peripheral edge 53 of movable bottom 29 and the strips 44,45.
  • the form and dimensions of the finally produced green brick is determined by the form and dimensions of the mould cavity defined in the mould container.
  • the distance a between the upright walls 40 and 41 determines for instance the lengthwise dimension of the green brick.
  • mould containers are mounted which have a relatively great mutual distance a, while for the manufacture of relatively short green bricks, the mutual distance a between the upright walls 40,41 can be small.
  • the mutual distance between the upright walls 42 and 43 which defines the transverse dimension of the green bricks.
  • the thickness d of the strips 44,45 fixed against walls 40,41 depends on the distance a between these walls 40,41. At a relatively great mutual distance a for the manufacture of more elongate bricks, the thickness d of strips 44,45 will have to be greater to be able to continue to ensure a good connection of the strips to the movable bottom 29.
  • the intermediate space between the inner wall and the movable bottom is at least 3 mm in order to prevent contact between the peripheral edge of the movable bottom and the upright walls of the mould container.
  • the width b of the strip is in that case at least 3 mm. So as to enable the greatest possible variation of mould cavities at determined dimensions of a movable bottom, the strip width can be varied from the said minimum values to a maximum value which depends, among other things, on the composition of the clay, the form of the mould container and the knock-out speed. Too great a width can result in the green bricks not being pressed properly out of the mould cavities, or the surface of the green bricks being damaged during knock-out.
  • the optimal width d of strips 44,45 depends on the differences in brick size which have to be processed by device 1. If for instance relatively small differences in the brick dimensions occur because of the shrinkage differences, which depend on the raw material used, for instance varying from 232 mm, 230 mm, 228 mm etc., the strips can be given quite a thin form. It has been found in practice that a strip width d of between 0.3 cm and 3 cm, or better still between 0.5 cm and 1.5 cm, produces satisfactory results.
  • one or more of the strips 44-45,47-48 are provided in a further preferred embodiment with an air gap 54. This provides an open connection between the space above movable bottom 29 and the space below movable bottom 29. The green brick being sucked fast against the walls of the mould containers or against the bottom is hereby avoided.
  • Figures 5A-5D show different preferred embodiments of the mould container with a fixed bottom part and a movable bottom.
  • Figure 5A shows the embodiment in which a strip 44,45,47,48 is arranged along the four walls 40-43 of the mould container, wherein the different strips all have the same width.
  • FIG 5B is shown an embodiment in which strips 44,45,47,48 are likewise arranged along the four upright walls 40-43, but in this embodiment the strips 44,45 along the end surface of the mould container are wider than the strips 47,48 along the longitudinal sides 47,48 of the mould container.
  • Figure 5C shows a further preferred embodiment in which strips are arranged only along front wall 41 and the left-hand side wall 42, while in figure 5D an embodiment is shown in which a strip is arranged only on front wall 41.
  • Which embodiment is preferred in a particular situation depends on the desired brick size.
  • the top side of the movable bottom and the underside of strip 44,45 are provided with respective chamfered edges 55 and 63 for simplifying placing of the mould containers on a chain part 17 provided with ejectors and movable bottoms 29.
  • Figures 6 and 7 show another preferred embodiment of the invention.
  • the support plate 27 is welded to chain part 17.
  • the exchangeable part of mould container part 3 is here the mould container 66.
  • the mould container is manufactured from lightweight material, such as plastic, and can be coupled simply and quickly using a rapid-action coupling 60 to support elements 50,51 of support plate 27.
  • Rapid-action coupling 60 comprises a number of pins 61 which protrude laterally from walls 40,41 and on which can engage hooks 62 arranged rotatably on support elements 50,51. In practice it is possible to suffice with three to six rapid-action couplings 60 per longitudinal side, i.e. a total of six to twelve rapid-action couplings 60.
  • the degree of deformability of the clay is important. If the clay is too soft an impression of the movable bottom will result in the green brick, which is of course undesirable. If the clay is too hard however, the mould containers are not completely filled, so that the green brick, particularly close to the edges thereof, acquires a rounded form. This is also undesirable.
  • the clay applied must therefore preferably have a deformability such that the remaining height measured in the method for determining the clay consistency, to be further described below, amounts to between 9 and 17 mm. The remaining height must be more than 9 mm so that the clay is not too soft, but must be less than 17 mm since otherwise the clay threatens to become too hard.
  • Pfefferkorn introduced a measuring method for providing a measure for clay consistency. This measuring method is generally applied in the European ceramics industry. The relation of the Pfefferkorn remaining height and the moisture content of a clay mass is found to be practically linear in a wide consistency range. The above mentioned recommended remaining heights are brought about by performing a measuring method using a measuring apparatus as shown for instance in figures 8A-8D .
  • the measuring apparatus 70 comprises a stand with base plate 71, a guide part with ratchet blocking under spring bias 72, a disc with vertical guide rod 73 (total falling weight 780 g, maximum drop height 100 mm) and a brass cylinder with a diameter of 33 mm and a height of 40 mm 74 with stamp 75 for removing the bar of clay for testing.
  • the measuring apparatus 70 In order to measure a quantity of clay, the measuring apparatus 70 must be disposed vertically with the guide rod in vibration-free manner.
  • the guide rod has thin oil applied thereto.
  • these elements are lightly oiled with a mixture consisting of 90% kerosine and 10% olein.
  • the clay for testing is kneaded and arranged in the brass cylinder while avoiding moisture loss, and levelled with a scraper knife. Using the stamp the bar of clay is then removed. The bar of clay for testing is now placed in the middle under the disc on the base plate, and the disc is then locked. After the drop of the disc the remaining height of the test piece is measured. An optimum manufacturing result can be achieved if the clay has a deformability corresponding to the remaining height of between 9 mm and 17 mm when measurement is carried out with the above described Pfefferkorn measuring method.
  • the clay is arranged by pouring it from above into mould containers of a circulating conveyor.
  • the movable bottoms push the clay out of the mould containers, since the time period between arranging of the clay in the mould containers and removal thereof is relatively short (typically less than a few minutes), the clay has almost the same deformability when it is released from the mould containers as when it is arranged therein. According to the invention the clay is therefore removed very quickly after forming, and therefore when it is still in plastic state.
