    BRICK MOULDING APPARATUS The present invention relates to a brick moulding apparatus for moulding bricks, where the brick moulding apparatus comprises a material container placed above a brick moulding table which is connected with a drive motor for rotation of the moulding table about an center axis and which moulding table is provided with at least one form cavity with form sides and a back plate which also constitute a form side, where the form cavity and the back plate is arranged for displacement in relation to each other, between a position being aligned with the form cavity and a position not aligned with the form cavity which thereby has an open bottom, wherein the brick moulding apparatus further comprises a stamping system arranged for pressing out the brick from the form cavity when the back plate is in the position not aligned with the form cavity.
    The present invention also relates to a method for moulding bricks using the brick moulding apparatus, computer program product comprising software code portions configured for, when run in the memory of a computer, executing the method.
    Prior art There are various kinds of bricks, produced in various kinds of ways and arranged for various kinds of reasons and purposes.
    Bricks were originally formed by laying clay in wooden forms. The bricks were then turned out and dried, before they were burned in ovens. To get the bricks out of the forms they were either flooded with water given the bricks a smooth surface, or the clay was rolled in sand before it was laid in the form, giving the bricks a sandy and rough surface. As the bricks produced in this way were made by hand they are called hand-moulded bricks.
    > DK 2019 70488 A1 Bricks are now made mechanically by means of brick moulding apparatus comprising brick moulding tables. These bricks are so-called soft-moulded bricks which are the bricks closest in form and shape to the original hand-moulded bricks.
    Alternatively are bricks made by means of extrusion, where plastic deformable material is pressed against a template and extruded in certain length with the required perforations in terms of form and number of holes to an outer form of a bricks length x width. After the extrusion, the length of plastic deformable material is then cut with wire strings in slices of a bricks height. These bricks are so-called machine-moulded bricks In terms of the visual appearance of the bricks there are also various options for processing the surfaces e.g. by using brushes or structure cylinders.
    When using the brick moulding apparatus as explained above it has shown that the bricks forms are totally regular when the brick is moulded. It is believed that this is due to the fact that the moulding table is continuously rotating also when the stamping system presses out the brick. Especially when angular shells are formed this causes a specific problem as the two part of an angular shell would not have a completely perpendicular orientation to each other. However, also rectangular bricks have a misalignment as the bricks could have different sizes and not be truly rectangular stones.
    It is believed that the problem with form stability and the problem with stones are partly due to the continuously rotation where one could say the bricks are formed "on the fly”.
    There have been a number of attempt to have the bricks formed with more regular forms.
    2 DK 2019 70488 A1 Object of the invention One object of the present invention is to obtain bricks where the form stability is increased.
    Another object of the invention is to obtain a method which is suitable for use in a brick moulding apparatus arranged according to the prior art principle. Description of the invention According to a first aspect of the invention, the above object is achieved with a brick moulding apparatus for moulding bricks of the type mentioned in the introduction and being peculiar in that the brick moulding apparatus further comprises stepping means arranged for stepwise angular rotation of the stamping system about the center axis of the brick moulding table, and interlocking means for interlocking the moulding table and the stamping system ensuring a mutual fixed position between the moulding table and the stamping system while pressing out the brick from the form cavity and that the moulding table and the stamping system while pressing out the brick from the form cavity is not rotating whereby the apparatus works according to a "stop-and-go”- principle.
    Surprisingly it has been found that a form stability is obtained in the bricks when it is ensured that a mutual fixed position is established between the moulding table and the stamping system while pressing out the brick and simultaneously ensuring that the moulding table and the stamping system is not rotating while pressing out the brick.
    One could say that the old system using “on the fly”-principle has been changed into an apparatus working according to a "stop-and-go”-principle.
    It has been found that the bricks produced with the moulding table arranged in a non-rotating condition during the activation of the stamping system for pressing
    1 DK 2019 70488 A1 out the brick make it possible to form bricks which are form stable. Especially, it has shown that angular shells are formed which has a perfectly perpendicular orientation of the two parts of the angular shell.
    It has also shown that a traditional brick could be obtained with truly rectangular form. The stepping means is arranged for stepwise angular rotation of the brick moulding table about the center axis of the brick moulding table. This makes it possible for a brick moulding table being a turntable to be able to rotate continuously 360 degrees in e.g. clockwise direction, where there from receiving the material to the ejection of the final formed brick in one option is 180 degrees between filling the form to ejection of the brick. From receiving the material to the ejection of the final formed brick could in another option be less than 180 degrees and from receiving the material to the ejection of the final formed brick could in yet another option be more than 180 degrees. Also 120 or 60 degrees are possible between the filling and the ejection. The brick moulding table at each stepwise angular rotation of the brick moulding table may comprise the same form cavity. This makes it possible to use all possible steps at the brick moulding table for the same process, the same kind of brick, hence shorter angular rotations of the brick moulding table between operations is possible. A further option, instead of using 180 degrees of the rotation of the brick moulding table, is to use a larger angular part e.g. 270 degrees. The conveyer belt below the brick moulding table onto which the bricks are ejected at obviously have to be placed below the point of ejection.
    Stepping means provides various options like e.g. mechanical stepping means or electrical stepping means.
    på DK 2019 70488 A1 According to a further aspect the brick moulding apparatus is peculiar in that the stepping means comprises mechanical stepping means. Mechanical stepping means is a technical simple solution.
    According to a further aspect the brick moulding apparatus is peculiar in that the mechanical stepping means comprises a circular ratchet and a cooperating displaceable tooth, which may be displaced between a position in engagement with the circular ratchet and a position without engagement.
    A circular ratchet and a cooperating displaceable tooth is an especially simple technical solution. With this solution it is possible to interlock the stamping system and the moulding table. Hereby only one motor, namely the motor used for rotating the moulding table need to be controlled and stopped while pressing out the bricks.
    However, the mechanical solution requires the movement of a heavy weight in form of the stamping system and other associated equipment arranged obn the same frame as the stamping system.
    Therefore it is also preferred to use electrical stepping means.
    According to a further aspect the brick moulding apparatus is peculiar in that the stepping means comprises electrical stepping means.
    The electrical stepping means makes it possible to eliminate the use of the heavy mechanical interlocking system.
    According to a further aspect the brick moulding apparatus is peculiar in that the electrical stepping means comprises a first controller connected with a first step motor for rotating the stamping system about the center axis and a second controller connected with a second step motor for rotating the brick molding p DK 2019 70488 A1 table, which second step motor is the drive motor for rotation of the moulding table about the center axis of the moulding table.
    By using step motors it is possible with the first and second controller to control the correct mutual position of the stamping system and the moulding table. Hereby it is possible to position the stamping system correctly in relation to a form cavity while pressing out the brick. When using step motors it is possible to effect the stop-and-go principle in a very efficient way. The formation of bricks may be associated with specific adaptation of the bricks, e.g. by providing holes in the bricks or by forming the bricks as shells, which are called brick slips.
    According to a further aspect the brick moulding apparatus is peculiar in that the brick moulding apparatus further comprises a brick punching system arranged for punching holes in bricks and that said brick punching system is arranged in fixed relation with the stamping system and for rotation together with said stamping system about the center axis. When the brick punching system is arranged in fixed relation with the stamping system it is possible to rotate the stamping system and the punching system with only one drive motor. Moreover, the mutual angular position between the two systems could correspond to the angular movement for a stepping. Hereby the stepping movement may bring a form cavity from a position below the punching system to a position below the stamping system. According to a further aspect the brick moulding apparatus is peculiar in that the brick punching system comprises a punching die which is arranged for acting towards the back plate, where the punching die comprises punching means
    , DK 2019 70488 A1 which is arranged for punching at least one hole in a brick and where the back plate comprises at least one hole which is complementary to the punching die. With this solution the brick will be maintained in the form cavity while material from at least one hole is removed through the back plate. According to a further aspect the brick moulding apparatus is peculiar in that the stamping system and the brick punching system is arranged with a mutual angular position which corresponds to a possible step for the stepwise angular rotation of the stamping system about the center axis.
    When the angular position between the stamping system and the punching system corresponds to a possible step the stepwise angular rotation becomes especially simple to control.
    According to a further aspect the brick moulding apparatus is peculiar in that the stamping system comprises an actuator which is connected with at least one pressing plate for pressing out the brick from the form cavity.
    The stamping system preferably have a pressing plate having a form corresponding to the form of the form cavity whereby it is possible to press out the brick from the form cavity with a uniform pressure distributed over the surface of the brick.
    Holes are defined as being either a bottom hole — a hole which one cannot look through - or a through hole — a hole which one can look through.
    With at least one hole there are a large variety of options available, whether that is three, four, eight or another number of holes.
    8 DK 2019 70488 A1 Bricks are defined as being either a brick or a brick slip. Bricks are known to be found in many different sorts and sizes, for example: 228 x 108 x 54 mm (length x width x height). Similarly are brick slips known to be found in many different sorts and sizes, for example: 228 x 25 x 54 mm (length x width x height).
    Bricks are further defined as being made of plastic deformable material e.g. a clay-water mixture. Form sides are defining the form of the cavity and hence the form of the brick which at this stage is constituted by plastic deformable material. This makes it possible to arrange a brick moulding table complete with a punching system at a brick moulding apparatus.
    One form is the minimum amount of forms however three or four forms are often used simultaneously at each process. With at least one hole is it possible to punch a mortar pocket into the brick, where a mortar pocket is a bottom hole, punched into a part of the brick to put mortar in during bricklaying. When punching the mortar pocket into the brick an equivalent amount of material is pressed through the hole in the back plate. The mortar pocket reduces the use of material for the brick, the weight of the brick and thereby the cost for transporting the brick. Furthermore, the time for drying and burning the brick is reduced.
    The back plate being complementary to the punching die means that the back plate comprises the equivalent number of holes as the punching die is arranged for punching and that the holes are arranged so that the material punched by the punching die is arranged for passing through the holes in the back plate.
    Among the options are bricks punched with 6 or 8 holes in two rows.
    o DK 2019 70488 A1 in another aspect, the present invention also relates to a brick moulding apparatus, where the brick moulding table al every other stepwise angular rotation of the brick moulding table comprises the same form cavity.
    This makes it possible to have two different processes arranged at one brick maulding table. An example is a three-step process having 120 degrees between its steps and another three-step process having 120 degrees between its steps, thus the moulding table would then have 60 degrees between different processing steps. An option is therefore to set up the brick moulding table for brick slipsijer.pan and for corner brick slips. in another aspect, the present invention also relates to a brick moulding apparatus, where the punching die further comprises a lid plate in order to close the form when the punching die acts against the back plate.
    This makes it possible to keep the brick material, e.g. clay, within the form of the brick when making a bottom hole as the material is not getting pressed out of the form in the opposite direction as the punching die is acting. By closing the form by a lid the material is only able io move in one direction and that is in the direction of the punching and out of the form through the holes in the back plats opposite the punching die. When a through hole is getting punched the pressure is not the same as when a bottom hole, e.g. a mortar pocket, is getting punched, however it keeps the material within the form when the punching die is withdrawn. in another aspect, the present invention also relates to a brick moulding apparatus, where the punching die comprises a pipe which is arranged for making a hole in a brick and a piston arranged within the pipe which is arranged for pressing the punched material out of the pipe.
    0 DK 2019 70488 A1 This makes it possible to punch a through hole without having to press all the excess material out at once, hence in a first step punching the pipe through the material and in a second step pressing the material out of the pipe. Thereby it is possible to produce a brick which is not convex on the surface and where visually the edges appear sharper.
    The punching process could be conducted in several steps or preferably in just one continuously movement.
    In another aspect, the present invention also relates to a brick moulding apparatus, where the punching die comprises means which is arranged for punching e.g. square, elongated or preferably circular holes in a brick.
    This makes it possible to punch various holes in a brick depending on the purpose of which the brick is produced. Variations are then plenty. Architects and other building designers use from time to time the largest surface of a brick - which is normally where the punches are — at the visible part of the brick.
    In another aspect, the present invention also relates to a brick moulding apparatus, where holes are20-30 mm, preferably 23-27 mm, further preferably mm in diameter.
    This makes it possible to punch various sizes of holes in a brick depending on the purpose of which the brick is produced. Variations are also plenty in this 25 regard, few holes with a larger diameter or many holes with smaller diameter.
    In another aspect, the present invention also relates to a brick moulding apparatus, where the punching die comprises means which is arranged for punching exactly three circular holes each of 25 mm in diameter in a brick.
    iy DK 2019 70488 A1 This makes it possible to produce a brick with the same strength as a solid brick, but a brick which reduces time for drying and time for burning, which further reduces weight and reduces about 8% of the material used in a solid brick. The excess material is then recycled and used to new bricks, hence there is a benefit regarding material costs, production cost as well as the working environment. In another aspect, the present invention also relates to a brick moulding apparatus, where the punching die comprises at least one spring arranged for spring-loading the punching die.
    This makes it possible to use springs for the purpose of returning at least part of the punching die to a normal unloaded position out of contact with the brick.
    In another aspect, the present invention also relates to a brick moulding apparatus, where the punching die is driven by an actuator.
    This makes it possible to use actuators, which is either electrical, pneumatically or hydraulically driven.
    In yet another aspect, the present invention also relates to a method for moulding bricks using the brick moulding apparatus, where the method comprises at least the following steps: Step 1: plastic deformable material is supplied to the brick moulding table from the material container above the brick moulding table, Step 2: at least one form cavity with form sides and a back plate which constitute a form side is filled with plastic deformable material constituting a brick, which method further comprises at least the following steps: Step 3: interlocking the rotation of the stamping system about the center axis of the brick moulding table, and the rotation of the moulding table in a mutual fixed position while pressing out the brick from the form cavity and maintaining the moulding table and the stamping system in a fixed angular position while
    12 DK 2019 70488 A1 pressing out the brick from the form cavity, thereby working according to a “stop- and-go”-principle.
    In a further step the brick is ejected.
    This makes it possible to produce a brick In yet another further aspect, the present invention also relates to a computer program product comprising software code portions configured for, when run in the memory of a computer, executing the method.
    This makes it possible to execute and run the method automatically.
