Description

Mould container part for the manufacture of bricks slips, mould container pressing device and method for application thereof
The invention relates to a mould container part for the manufacture of brick slips, a mould container pressing device provided with such a mould container part, and to a method for applying a mould container pressing device with such a mould container part.
When brick slips are arranged on a wall, this wall will acquire the visual appearance of a wall erected from bricks. Brick slips are therefore applied for the purpose of embellishing flat walls.
Because the construction of buildings from concrete, wood or other constructions is on the increase, and these are often insulated with polystyrene or PUR panels, after which brick slips of traditional appearance are then adhered thereto, the demand for brick slips is increasing. Insulating walls provided with brick slips are also often placed in renovation projects.
Brick slips are conventionally manufactured by sawing a fired brick into strips. This method has several drawbacks. A large quantity of waste material is thus created during sawing, and the sawing results in noise and dust emission. In addition, the saws and the sawing machines are subject to wear. Another regular occurrence is that a brick wholly or partially breaks during the sawing and becomes unusable. The whole brick, including all the waste material, has undergone a complete drying and firing process, and this costs time and energy. The energy consumed in respect of the waste material is wasted. Finally, this conventional sawing method is labour- intensive.
Because of the increased demand for brick slips, there is a need for an improved method for the manufacture of brick slips.
DE-A1 -3400380 discloses a moulding container pressing device with a mould conveyor, the mould containers of which are formed from two halves which are attached to each other for pivoting around a pivot axis and which fold open for the purpose of releasing the green bricks when the mould conveyor runs over a sprocket.
NL-A2-6913272 discloses a method for manufacturing moulded bricks, wherein the green bricks are cut into pieces, each the size of a brick, in their mould containers prior to drying.
EP-A1-2085199 in the name of applicant shows a mould container part wherein a plate is arrangeable against a side wall of the mould container in order to influence the size of the green brick to be formed in the mould container.
An object of the present invention is to provide a mould container pressing device and method for application thereof wherein the stated drawbacks do not occur, or at least do so to lesser extent.
Said object is achieved according to the invention with the mould container part for manufacturing brick slips, comprising one or more mould containers for forming therein a green brick from clay for the brick manufacturing industry, the mould container part comprising at least two slip moulding parts which are movable relative to each other and which are movable between a filling position, in which the green bricks are mouldable, and a release position in which the slip moulding parts arc removed from one another, and wherein two cross-sectional openings arc arranged in the side walls of the mould containers. Because the slip moulding parts are removed from each other in the release position, the green brick parts received therein during operation are separated from each other and releasable.
Although it would suffice for brick slips with the thickness of a half -brick to arrange a single cross-sectional opening in the middle of the green brick, brick slips normally have narrower dimensions. In order to double the production capacity for such brick slips a second cross-sectional opening is arranged in the side walls of the mould containers. In addition to increasing the production capacity, this has the further advantage that the mould container is sufficiently wide to enhance repeated and complete filling of the mould container with clay.
With the mould container part according to the invention it is possible to use filling means of a traditional mould container pressing device for conventional bricks. The green brick formed by these filling means is after all only brought to the desired thickness of the brick slips by dividing the green brick after the moulding. By using conventional filling means tested and reliable techniques can on the one hand be used. Direct pressing of a green brick with the small thickness of a brick slip causes problems, such as the difficulty of filling the mould container. By applying conventional filling means a brick slip will on the other hand be obtained which exactly corresponds visually to a standard brick formed with such filling means. A wall covered with such brick slips cannot therefore be distinguished visually from a wall erected from bricks.
Because each green brick can provide two bricks slips at a time, the production capacity which such a mould container part can provide is moreover doubled compared to a conventional mould container pressing device.
A further important advantage is that the mould container part provides green brick parts in the size of a brick slip, whereby only the net product need be subjected to a drying and firing process. Because these green brick parts are much thinner than a green brick for a conventional brick, it will moreover be possible for this drying and firing process to proceed more quickly and consume less energy.
According to a preferred embodiment, the slip moulding parts face toward each other in the filling position and form walls of the mould container, wherein the at least two slip moulding parts movable relative to each other are pivotable relative to each other between the situation in which they face toward each other in the filling position and in which they form walls of the mould container and the release position in which the slip moulding parts comprise a substantially lying orientation. A mould container of conventional dimensions, i.e. similar to a green brick for a traditional brick, is thus formed in the filling position. The walls of the traditional brick will form the walls of the green brick part, and thereby the visual side of the final brick slip. The substantially lying orientation is defined in the lying part of the conveyor of the mould container pressing device. The cutting plane of the green brick part is directed upward here and is suitable in this substantially lying orientation for receiving thereon a drying plate on which the green brick parts can finally be discharged and transported to the drying process and subjected thereto. The visual side of the final brick slip is oriented downward and received in the respective slip moulding part.
The hinges are placed such that the slip moulding parts are pressed toward each other under the influence of the pressure during the pressing, thereby preventing the possibility of the mould container opening under the influence of the pressure.
A structurally elegant cross-sectional opening is obtained when according to yet another preferred embodiment a first of the two cross-sectional openings is formed in the side walls of the mould container in that the two slip moulding parts of the mould container part movable relative to each other are arranged on two adjacent conveyor parts of a circulating conveyor, and wherein the separation between these conveyor parts forms a first cross-sectional opening in the mould containers.
According to a further preferred embodiment of the mould container part, one or more slip moulding parts provide at least two protruding parts extending inside a mould container. By providing the slip moulding parts with protruding parts the shape of the green brick part to be moulded in the respective slip moulding part can be modified. The green brick part will after all be a negative impression of the space enclosed by the slip moulding part.
Green brick parts with at least two protruding parts and a recess therebetween provide advantages such as enabling simple and reproducible arrangement on prefab constructions, wherein the protruding parts can for instance be pushed under prearranged hook parts or arranged in other manner. By placing the protruding parts of adjacent brick slips abutting each other a desired spacing can also be obtained for the later arrangement of pointing between adjacent brick slips.
According to a further preferred embodiment, the at least two parts protruding inside the mould container are arranged some distance from each other against the same wall of the mould container. The projecting parts to be formed on the green brick part are hereby interrupted by recesses. These recesses simplify the arrangement of a projecting part of a brick slip under a hook part on a prefab construction because the hook parts can be guided in through the recesses between the projecting parts. A projecting part can then be brought into engagement with a prefab hook part with a small sliding of the brick slip. Such a prefab construction does not form part of this application. According to a further preferred embodiment, the protruding parts comprise a longitudinal strip arranged in longitudinal direction of the slip moulding part and/or a transverse strip arranged in transverse direction of the slip moulding part, wherein one or more further protruding parts are provided on the longitudinal strip and/or on the transverse strip. These one or more further protruding parts provide the projecting parts which arc to be formed on the green brick part and which are interrupted by recesses.
The invention further relates to a mould container pressing device for manufacturing brick slips for the brick manufacturing industry, comprising a circulating conveyor comprising a number of mould container parts, wherein each mould container part comprises one or more mould containers for forming a green brick from clay therein, wherein a cutting member is provided with which the green brick formed in the mould container is divisible into green brick parts, and wherein the mould container part is a mould container part according to the invention. The cutting member cuts through the green brick formed in the mould containers at a predetermined distance from the side walls of the mould container formed by the slip moulding parts. This predetermined distance corresponds to the thickness of the green brick part which will eventually form the brick slip following drying and firing.
According to a preferred embodiment of the mould container pressing device, the cutting member comprises a substantially flexible endless member. Such a flexible endless member can for instance be a cord which can cut through the still wet clay. Such a cord is considerably less expensive than the saws according to the prior art brick slip production techniques which are susceptible to wear.
When according to yet another preferred embodiment a middle moulding part is provided between the slip moulding parts, a green brick with the size of conventional brick can be manufactured, from which can then be cut narrow green brick parts for the brick slips. The green brick to be moulded initially by the mould container pressing device can be shaped into a brick size via a proven and optimized process, after which thin slips can be taken therefrom. An important further advantage is that the appearance of the visual side is identical to that of a conventional brick.
A part of the clay can already be removed and recycled early in the manufacturing process when according to yet another preferred embodiment a discharge member is provided with which clay present in the middle moulding part can be dischar ged. Only the net product need hereby be subjected to a drying and firing process. Because these green brick parts are much thinner than the green brick of which they formed the side walls, it will moreover be possible for the drying and firing process for the green brick parts to proceed more quickly and consume less energy.
According to yet another preferred embodiment, the discharge member comprises gripping members and/or suction means. An undesired displacement of the slip moulding parts from the filling position to the release position, and vice versa, is prevented according to a further preferred embodiment in that holding means are provided which are configured to hold the slip moulding parts fixedly in the filling position and/or release position.
According to yet another preferred embodiment, the holding means comprise at least one spring which is connected to the slip moulding parts and which is configured to force the at least one slip moulding part connected to the at least one spring into the filling position and/or into the release position, and wherein one or more position reversal actuators are provided which are configured to move the slip moulding parts counter to the spring bias from the filling position to the release position, and vice versa. The position reversal actuator can for instance comprise a plunger or a cam guide.
The invention further relates to a method for manufacturing brick slips from clay for the brick manufacturing industry with a mould container pressing device, comprising the steps of:
- driving a circulating conveyor comprising a number of mould container parts, wherein each mould container part comprises one or more mould containers for moulding a green brick therein;
- advancing the conveyor under filling means, wherein green bricks are formed by filling the one or more mould containers with clay;
- cutting through one or more green bricks formed in the mould containers with a cutting member;
- displacing the cutting member through two cross-sectional openings arranged in the side walls of the mould containers; and
- moving slip moulding parts from a filling position to a release position, wherein the slip moulding parts face toward each other in the filling position and form walls of one or more mould containers in which one or more green bricks are mouldable, and wherein in the release position the slip moulding parts are removed from each other such that the green brick parts received therein are separated and releasable.
The cutting member can for instance comprise two above described cords which cut through the still wet clay of the green brick. In order to shorten the cutting time, the green bricks are preferably cut through simultaneously on two cutting planes by simultaneously displacing a first chord through a first cross-sectional opening and a second cord through a second cross- sectional opening.
According to a preferred embodiment of the method, the step of cutting through one or more green bricks formed in the mould containers with a cutting member comprises of cutting through these green bricks in longitudinal direction.
According to a further preferred embodiment of the method, moving the slip moulding parts from the filling position to the release position comprises of pivoting the slip moulding parts and green brick par ts formed therein to a substantially lying orientation.
According to yet another preferred embodiment of the method, a middle moulding part is provided between the slip moulding parts and the method further comprises the step of discharging clay present in the middle moulding part with a discharge member. The discharged clay can be recycled and moreover need not be subjected to a drying and firing process.
According to yet another preferred embodiment of the method, a mould container part and/or a mould container pressing device according to the invention are applied.

The mould container pressing device 1 shown in figure 1 comprises a circulating conveyor 24 assembled from a plurality of conveyor parts 26. Provided on the conveyor parts are rollers 28 which engage in chain wheels (not shown) whereby conveyor 24 is drivable. Arranged on conveyor parts 26 of conveyor 24 are mould container parts 2 which will be elucidated in more detail below.
The different production steps will now be briefly elucidated with reference to figure 1 , after which the steps relevant to the present invention will be discussed in more detail with reference to the following figures. Arranged above conveyor 24 is a filling device with which clay is arranged in the mould container parts 2 thereunder. Each mould container part 2 has in the shown embodiment four mould containers 4 in which one green brick at a time is mouldable.
Once the clay has been arranged in mould containers 4 of mould container parts 2, surplus clay is cut away with a first cutting member 52 so that a green brick 32 is created which on the upper side lies substantially flush with the upper side of mould container part 2. In the shown embodiment cutting member 52 comprises a cord 56 which runs over two rollers 54 and is tensioned directly above mould container part 2 and cuts thereover.
Once the surplus clay has been removed from green bricks 32, this clay waste 58 is picked up with a first discharge conveyor 60 and set down onto a second discharge conveyor 61 . The clay waste 58 is carried away by second discharge conveyor 61 and preferably reused.
Once green bricks 32 have been moulded in mould containers 4 of mould container part 2, they are divided according to the invention. Although this will be elucidated in detail with reference to figures 6 and 7, it is noted here that a second cutting member 62 comprises rollers 64 over which runs a cord 66. This cord 66 is displaceable in height direction with second cutting member 62, and as a result of this height displacement the green brick 32 is divided into two green brick parts 34 and surplus clay 72 present between these green brick parts 34.
This surplus clay is subsequently discharged as clay waste 72 in a further step by a discharge member 68, which for instance comprises gripping members and/or suction means 70, and preferably reused.
Drying plates 74 are then placed on the green brick parts 34 and, by further rotating the conveyor 24, carried to a position in which drying plates 74 are situated under mould container parts 2. In order to prevent the drying plates falling off, tensioning straps or chains are used which press drying plates 74 against mould container part 2 when they pass over a chain wheel (not shown).
When drying plates 74 are situated on the underside of mould container parts 2, they are gradually moved off mould container parts 2 and the green brick parts 34 formed by mould container pressing device 1 will come to lie on drying plates 74. Drying plates 74 with the green brick parts 74 present thereon are then discharged for further treatment. The green brick parts 34 are first placed in a drying chamber where they will be dried before being fired to a hard brick in a kiln.
Figure 2 shows two successive conveyor parts 26 of conveyor 24, wherein a mould container part 2 is located at the transition between these two conveyor parts 26. In the shown embodiment each mould container part 2 has four mould containers 4 and comprises at least two slip moulding parts 6 movable relative to each other and movable between a filling position (position has shown in figure 2), in which green bricks 32 are mouldable, and a release position (as shown in figure 8 and other figures) in which slip moulding parts 6 arc removed from each other and wherein the green brick parts 34 received therein are separated from each other and releasable.
In the orientation of slip moulding parts 6 shown in figures 2, 3 and 4 they face toward each other and form the walls 8 of mould containers 4. This orientation corresponds to the filling position in which green bricks 32 are mouldable in mould containers 4. In the shown embodiment the slip moulding parts 6 movable relative to each other are pivotable relative to each other in that they are each arranged on a pivot shaft 10. When slip moulding parts 6 each rotate about their own pivot shaft 10, they displace from the filling position shown in figures 2, 3 and 4 to a release position in which slip moulding parts 6 have a substantially lying orientation.
Tn order to ensure that slip moulding parts 6 remain in the desired filling position or release position, holding means 38 are provided which can retain these positions. The holding means comprise a cam member 40 which rotates around pivot shaft 10 and which is connected with a shaft 48 to a slide member 44. The slide member is slidable over a shaft 42 and is biased by a spring 46. The spring bias of spring 46 ensures that slip moulding parts 6 are held fixedly in the filling position or in the release position. By using position reversal actuators (not shown), for instance plungers which press cam members 40 aside, the spring bias of spring 46 can be temporarily overcome and slip moulding parts 6 can be urged from the filling position to the release position, and vice versa.
Shown in the view of figure 3 is how a mould container part 2 extends over two conveyor parts 26. Each mould container part 2 is formed from slip moulding parts 6 and a middle moulding part 12 located therebetween. Together the slip moulding parts 6 and the middle moulding part 12 enclose a mould container 4 which coiTesponds in dimensions to a mould container for for instance conventional bricks. Although there are variations in these dimensions, conventional bricks are characterized by the much greater thickness compared to a brick slip. There is a great deal of experience with filling of brick-size mould containers 4 and this proven technique allows highly reliable and good results. Owing to the combination of slip moulding parts 6 and middle moulding part 12 use can thus be made of this proven and fully developed technique, whereby a highly reliable and consistent filling of mould containers 4 is guaranteed.
Showing conveyor parts 26 in spaced-apart view in figure 4 indicates clearly how each mould container part 2 is divided over two conveyor parts 26. An advantage of this setup is that a natural separation is created between a middle moulding part 12 and a slip moulding part 6 through which green brick 32 can be divided, as will be further elucidated with reference to figures 6 and 7. Figure 5 shows the situation in which slip moulding parts 6 are moved from the filling position shown in figure 4 to the release position shown in figure 8. Figure 5 shows an intermediate position in which cam members 40 are operated by position reversal actuators (not shown) and a slide member 44 presses over shaft 42 of holding means 38 counter to the spring bias of spring 46.
For the sake of clarity figures 2-5 arc shown without green bricks 32 arranged therein.
Figures 6 and 7 show how a green brick 32 is divided into green brick parts 34 and possibly surplus clay material 72.
In figure 6 the clay protruding on the upper side of mould container part 2 has already been discharged using first cutting number 52 and discharge conveyors 60, 61. By then displacing a second cutting number 62 in height direction through mould container parts 2 the green brick 32 present therein is divided into green brick parts 34 and surplus clay 72 lying therebetween.
In order to make second cutting number 62, which in the shown embodiment comprises a cord 66, displaceable in height direction through green brick 32 a first cross-sectional opening 18 and a second cross-sectional opening 20 are provided in mould container part 2. Tt is noted here that first cross-sectional opening 18 comprises the separation between two successive conveyor parts 26 of the circulating conveyor.
Cords 66 will cut through green bricks 32 better by having cords 66 of second cutting number 62 run over rollers 64 and driving them in circulating manner when cutting number 62 is displaced in height direction.
Once green bricks 32 have been divided into green brick parts 34, the surplus clay 72 present therebetween in the middle moulding parts 12 can be discharged using a discharge member 68 (figure 8). In the shown embodiment the discharge member 68 is provided with gripping members/suction means 70 which pick up the clay waste 72.
Because only the green brick parts 34 which will form the brick slips will be set down onto drying plates 74, only the net end product will be subjected to a complete driving and firing process. The surplus clay - which makes possible a reliable and consistent filling of mould containers 4 - can already be discharged directly after filling of mould containers 4 and if desired reused.
Figures 9-10, 11-12 and 13-14 form pairs of three alternatives slip moulding parts 16 for moulding green brick parts 34 provided with one or more protruding parts 16.
By providing slip moulding parts 6 with protruding parts 16 the form of the green brick part 134, 234, 334 to be formed in the respective slip moulding part 6 can be modified. The green brick part will after all be a negative impression of the space enclosed by slip moulding part 6.
Green brick parts 134, 234, 334 with protruding parts 116, 236, 336, 337 offer advantages such as enabling simple and reproducible arrangement on prefab constructions, wherein the protruding parts 116, 236, 336, 337 can instance be pushed or otherwise arranged under prearranged hook parts. By placing protruding parts 116, 236, 336, 337 of adjacent brick slips abutting each other a desired spacing can also be obtained for the pointing to be arranged later between adjacent brick slips.
In figure 9 a protruding part 16 in the form of a longitudinal strip 116 is provided on wall 8 of slip moulding part 6. A green brick part 134 formed in slip moulding part 6 of figure 9 will be without clay on its longitudinal sides 135 where longitudinal strip 116 was placed during moulding. As a result a protruding longitudinal edge 136 is created extending on longitudinal sides 135 of green brick part 134 (figure 10). Using this longitudinal edge 136 a brick slip manufactured from this green brick part 134 can be hooked easily under a hook part, which can be advantageous for prefab constructions. Such a brick slip is hereby particularly suitable for instance for prefab constructions wherein hook parts are provided on insulating plates or strip parts to be placed beforehand.
When protruding part 16 comprises a longitudinal strip 216 with further protruding parts 217 arranged thereon (figure 1 1 ), it will be possible to provide the corresponding green brick part 234 along its longitudinal sides 235 with short projecting parts 236 between which lie recesses 238. Recesses 238 between the projecting parts make it possible for a brick slip to be placed by guiding a hook part via recess 238, after which the brick slip is pushed sideways to some extent so that the hook part comes into engagement with a projecting part 236.
In figure 13 slip moulding part 6 also comprises in addition to a longitudinal strip 316 a transverse strip 317. A corresponding green brick part 334 is shown in figure 14 and comprises a longitudinal edge 336 extending along the longitudinal side 335 of green brick part 334, and a transverse edge 338 extending along the end surface 337 of green brick part 334. A transverse edge 337 on the end surface is particularly advantageous because adjacent brick slips are now placeable with their transverse edges against each other and can thus define a perfect pointing width.
Transverse edge 338 preferably extends half the distance of the desired pointing width from end surface 337 so that each brick slip contributes half the distance of the pointing width. It is of course also possible to envisage the brick slips being provided on only one end surface 337 with a transverse edge 338, which then extends roughly the whole distance of the desired pointing width from end surface 337, although this could have the drawback that the orientation of placing of adjacent brick slips is no longer free.
Although it shows a preferred embodiment of the invention, the above described embodiment is intended only to illustrate the present invention and not to limit the specification of the invention in any way. The skilled person will appreciate that measures of the different embodiments can be combined, such as for instance providing recesses 238 as according to figures 11 and 12 in a transverse edge 338 on an end surface 337 of a green brick part. When measures in the claims are followed by reference numerals, such reference numerals serve only to contribute toward the understanding of the claims, but are in no way limitative of the scope of protection. The described rights are defined by the following claims, within the scope of which many
modifications can be envisaged.
