    Method of manufacture for corner shells and apparatus therefor
    INTRODUCTION DESCRIPTION
    BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a method and apparatus for making bricks or clinkers, in particular stone shells and shingles, which are formed of a basic ceramic material, typically clay, and burnt. The invention also relates to an application thereof for the production of brain shells.
    To make the interior or exterior facades of a house look like a facade that is bricked with whole bricks, it is common to coat the facade with tile shells. In order not to disturb the appearance of the wall at the facade corners, angular shells with dimensions corresponding to the width and length of the stone to be imitated are usually used.
    To produce an angular shell one can cut a smaller rectangle out of an already burnt brick, leaving the angular shell behind. However, this is a relatively time-consuming manufacturing process. In a known method, therefore, a strand is formed by means of an extruder, the later angular shells being connected to a support stone by means of bridges. This shaped string is cut into individual shaped bodies and burned. By breaking the bridges between the angle shell and the carrier after firing, the angle shell is released from the carrier. Alternatively, an angular shell of the support is cut by means of a cutting thread immediately during the pressing process. In this method, however, the angular shell for stabilization during firing lies on the carrier with its entire surface and is removed with little force from the carrier after firing. In these three cases, the carrier remains as waste material.
    In order to avoid such waste, the European patent application EP0982108 discloses a method in which, by means of an extruder, an angled shape string is pressed which corresponds in cross section to the later angular shell. This mold strand is subjected to a surface treatment and separated into individual shaped bodies which are then placed so that they rest on the angled edge and burned.
    DK 2018 70184 A1
    For particularly soft base materials of clay such as those used for soft-coated bricks and especially water-coated bricks, this method is not suitable because the shaped bodies for angular shells are easily deformed upon handling.
    Furthermore, in German patent application DE102010004108 such a method is considered a disadvantage in that the nozzle of the extruder has to be adapted to the specific manufacture of stone shells and the brick brick. To remedy this, a method is described by which, before drying, a blank must be separated from a brick slab by punching. In order to keep the wave shells stable during the firing process, several angle shells are stacked on an angled metal carrier.
    Although this latter method per se seh 7 provides an improvement over the prior art, it nevertheless has shortcomings in certain areas. For example, the surface of the angular shell is easily damaged by the stacking, especially when soft types of clay are used which are used for the characteristic water-coated bricks, where an uneven surface which is individual for each stone is desired.
    Therefore, there is a general need to improve manufacturing processes, especially for water-fired bricks.
    DESCRIPTION OF THE INVENTION
    It is therefore an object of the invention to provide an improved method and apparatus for making bricks, in particular stone shells and angular shells, for example for water-stained stone shells or water-stained corner shells. The following describes a method and apparatus for making angular bodies, in particular angular clay, formed and burnt from a ceramic base material.
    In the following, the term "brick" is generally used, see 7, whether the shaped bodies described may also be hard-burnt clinkers. Since the difference mainly depends on the firing temperature, which is not essential to the process described herein, the term bricks also includes clinker.
    DK 2018 70184 A1
    Briefly, the invention of a ceramic base material in matrices makes angular bodies paired with corresponding saddles and arranged on a conveyor such that the molded shaped body sits on the saddle for drying. For example, the matrices are interchangeable parts of a die wheel which takes up the base material and places it on a conveyor through openings in the matrices. This matrix principle is also well suited for the manufacture of block bricks which are block-shaped. Details and embodiments are explained in greater detail below.
    In the method, a first base material for a single shaped body is pressed through a first shape whose cross section corresponds to that of the shaped body. A second base material, typically from the same source as for the first base material, is pressed through a second mold to a saddle adapted to the shaped body for support. The cross-section of the other shape corresponds to the cross-section of the saddle. Advantageously, the resulting shaped body and the resulting saddle are received on a conveyor. Upon joining, the shaped body to support and maintain its shape stability is placed on the saddle and then dried along with the saddle. After drying, the shaped body is removed from the saddle and burned without a saddle. With trout, the saddle that is not braked is reused in the manufacturing process of a new shaped body so that the base material of the saddle is not wasted.
    In a practical embodiment, the shaped body and saddle are manufactured simultaneously. Advantageously, the shaped body and saddle are automatically joined in pairs.
    For example, to minimize transport paths, the first and second forms lie at a distance, especially a small distance, adjacent to each other with approximately the same configuration as the final combination of the angular body and saddle during drying. Thus, the shaped body can be supplied to the saddle in a simple manner and placed thereon.
    For example, the angular body and saddle are pressed from top to bottom through the first and second molds, thereby being laid down on the conveyor.
    DK 2018 70184 A1
    In a further practical embodiment, the conveyor turns the shaped body and saddle in an automatic course through a right angle and positions them so that the molded body and the saddle are assembled before, after or during the rotation and the shaped body is thus mounted on the saddle. The saddle typically has upper surfaces which, for support, correspond to the underside of the angular body.
    For example, the conveyor comprises a conveyor belt with which the combination of the shaped body and saddle is fed into a production section arranged for drying.
    An example of the device comprises a die wheel rotating about a vertical axis containing at least one but typically several dies. The die comprises a frame attached to the die wheel with a vertical through opening whose cross section corresponds to the shaped body.
    Normally, but not necessarily, these matrices are similar to ensure a fast and efficient production process. For such a die wheel, the dies are advantageously interchangeable. For example, the dies are screwed in to the die wheel and can be removed again not only to replace them after wear but also to allow various die forms to be inserted into the die wheel as dies. Thereby, it is not necessary to replace the entire die wheel, which minimizes the amount of work and downtime of the production plant.
    In particular, the device comprises a first and a second set of interchangeable matrices, each comprising at least one matrix, but typically, however, several matrices in which the vertical through openings in the first and second sets of matrices are different.
    For example, two sets of matrices are used for different types of block-shaped bricks, where the difference in type on the bricks is size and / or shape. For example, some block-shaped bricks are longer than others.
    Thus, the first set of matrices is inserted into the die wheel for that manufacture. The piston of the piston press is adjusted to the matrices. For a changed product
    DK 2018 70184 A1 tion removes the first set of matrices from the die wheel and the second set of matrices is inserted into the die wheel and the piston is adjusted to the second set of matrices.
    Using the matrices allows quick and easy switching from the manufacture of block-shaped bricks to stone shells or single shells.
    While the die wheel rotates during manufacture, the base material from a base material container is laid down on the die wheel and pressed into the molds.
    Advantageously, for transferring the shaped body from the opening to an underlying conveyor, the device comprises a piston press having at least one piston for pressing through the opening. The shaped bodies are pressed out of the die with a corresponding piston press to be carried away from the die wheel on a conveyor.
    For example, if matrices are used for block-shaped brick brick or stone shells, a number of parallel slots are provided side by side in the matrix.
    For the concrete example of the angular body and saddle, the through-opening, for example, consists of at least one first shape and at a distance therefrom adjacent to the second shape, the first shape having a cross-section which substantially corresponds to the cross-section of the finished angular body, and wherein the second shape has a cross-section which substantially corresponds to the cross-section of the saddle adapted to the shaped body.
    Advantageously, the first and second forms are provided as pairs which lie side by side in a die. For example, the distance between the first and second forms is less than the thickness of the shaped body at the position supported by the saddle so as to keep the distance to receive the shaped body on the saddle short.
    The method and apparatus are particularly suitable for making corner shells, but are also generally useful for making other angular bodies that tend to twist during drying, for example T-shaped bodies. The die wheel is also useful for making simple shaped bodies, such as block-shaped bricks
    DK 2018 70184 A1 bricks and clinker, especially made of clay. Also for the preparation of other ceramic bodies before firing, the die wheel can be used advantageously.
    BRIEF BI SK RI VE i, SEE THE FIGURES
    In the following, a preferred embodiment of the invention will be explained with reference to the figures. In these shows
    FIG. 1 is a photograph as an example of a device for making water-stained bricks;
    FIG. 2 is a photograph as another example of a device for making water-stained bricks;
    FIG. 3 is a drawing of an alternate mold wheel:
    FIG. 4 shows a sketch of a device for making angular shells, FIG. 5 is a sketch of a die for an angle shell.
    DETAILED DESCRIPTION
    The one shown in FIG. 1, a die wheel 2 comprises a plurality of dies 3. Each die 3 has a plurality of die openings 4 through which a ceramic base material, typically clay, is pressed. In addition, this base material from a base material container 5 is loaded into portions on the die wheel 2 and filled into the die openings 4 and then finally pressed through the die openings 4 with a piston press 8. In the illustrated example of FIG. 1, bricks 6 are formed and set high on a conveyor belt 7 for further processing, especially for drying and subsequent burning.
    The same principle in FIG. However, you are also suitable for making stone shells where the die openings 4 thereto are narrower, for example in a custom die wheel 2 or in inserts inserted into the die openings 4.
    The one shown in FIG. 2 shows a slightly modified mode of operation, in which the bricks 6, after pressing through, are laid with their large surface on an intermediate conveyor 7 'but then turned by means of a flip-flop 9 from a supine position to a longitudinal position. In addition, the bricks are taken with a fork, which goes under them
    DK 2018 70184 A1 single bricks 6 on the large flat side and under a long side. The opposite, ultimately upward, long side is not affected, which is also important to give the water-colored brick the typical look that resembles a handmade production. The further transport on the conveyor belt 7 for drying and firing is similar to FIG. 1.
    The devices of FIG. 1 and 2 comprise die openings 4 extending in their longitudinal opening to the outer edge of the die wheel 2. In the example shown, this is advantageous since the conveyor belt 7 thus moves approximately tangentially to the die wheel 2. However, it is not absolutely necessary and the die 3 orientation must then be adapted to the course of the conveyor belt 7 or other means of transport. For example, FIG. 3, a die wheel 2 with dies 3, in which the longitudinal direction of the die openings 4 is provided approximately tangentially.
    Since the matrices 3 of the die wheel 2 of FIG. 3 is provided with interchangeable die inserts 10, the direction of the die openings 4 can be changed to adapt them to the production conditions. The die inserts 10 thus provide the die wheel 2 not only with greater flexibility in adapting to production conditions but also with a view to ongoing production, for example alternating brick brick production and scaling stone production. Thus, the entire die wheel 2 does not need to be replaced but only the die inserts 10 or die 3 as the production process changes. It should be noted that the replacement of the die inserts 10 or the dies 3 is easier and much faster than the replacement of an entire die wheel 2.
    The individual die inserts 10 may also be combined into a replaceable die 3 so that the entire die 3 forms a unit with die openings 4 in a die frame 12, typically rectangular frame. One such example is shown in FIG. 4th
    FIG. 4 shows a plan view and below a side view of a die 10 provided with screw fasteners 11 on opposite sides for mounting in the die wheel 2. The die 10 has a die frame 12 with several rectangular die openings 4, for example for straight stone shells or for whole block-shaped bricks. or clinker.
    DK 2018 70184 A1
    FIG. 5 shows an alternative die 3 comprising a die frame 12 having a triangular opening 13 and an L-shaped opening 14 only a short distance from the two short sides of the triangular opening 13. These two openings 13, 14 are filled in production with the base material. which is then pressed out of the respective openings 13, 14 with appropriate pistons from the piston press, for example down onto an underlying conveyor belt, as shown in the examples in FIG. 1 and FIG. 2nd
    FIG. 6 shows an example of a die wheel 2 into which such die 3 is inserted. Generally, several of such matrices are provided in such a die wheel 2. As the die wheel 2 rotates, the die 3 becomes filled with base material as it passes under the base material container 5, the excess base material is removed and after reaching the position of the die 3 shown in the figure. the corresponding base material triangle from the triangular aperture 13 and the still soft base material angular shell from the L-shaped aperture 14 deposited on a downwardly extending intermediate conveyor 7 'before being passed to a conveyor belt 7 as illustrated and explained in a conveyor belt 7 connection with the principle of FIG. 2nd
    Due to transhipment at turning 9, the L-shaped angular shell is automatically deposited on the base material triangle such that the triangle supports the angular shell as a saddle during further transport and drying. After drying, the angular shell is removed from the triangle and burned, while the triangle is not burned but reused in the process.
    It has been found that angular shells in this way are hardly deformed during drying, which is otherwise easily done by drying. It is believed that the exchange of moisture between the triangle and the angle shell exerts a positive effect on angular stability, and any angular change is ultimately less than when, for example, a corresponding metal support is used.
    Further advantages are obtained through the triangles by largely avoiding the handling of the very soft base material by water-coated bricks. For example, a transhipment of angular shells as shown in the above EP0982108 by the soft water-colored bricks is practically impossible without deformation.
    DK 2018 70184 A1
    Another advantage of basic material triangles is that as many triangles are made and available as angular shells, thereby providing a great deal of flexibility in sizing the production capacity with necessary saddles. With the method, at least in terms of the required number of saddles, no bottle5 throat arises due to possible under-sizing. Here, it should be recalled, as already mentioned above, that stacking multiple angular shells on a saddle is disadvantageous as the surfaces are damaged. Even in the case of surface staining before drying, stacking is not suitable for angular shells.
    The shape of the saddle as a triangle is chosen as an illustrative example. However, the saddle may take other forms as long as it supports and supports the shaped body. The angular body is not necessarily L-shaped, but may also have other shapes, for example T-shaped. Important in this context is largely to prevent deformation.
