    Title: Method for treating stones in order to give the stones an outdated appearance
    The invention relates to a method and a device for treating stones in order to give the stones an outdated appearance. This way of working with stones will hereinafter simply be regarded as the aging of stones.
    For the purpose of aging stones, it is customary to use a rotating tube and to place a package of stones in that rotating tube. In this way it is achieved that the stones are subjected to a so-called drum treatment, whereby pieces of the corners and edges of the stones jump off due to interaction of the stones and scratches occur on the flat sides of stones. At the end of a drumming operation, the stones are taken from the tube and stacked manually or with the help of a sorting system to form a package.
    The known method for aging stones has a number of disadvantages. First, the method is cumbersome and labor-intensive. This is related to the fact that an already formed package of stones, which is stacked on top of one another. layers of stones has been assembled, falls apart in the drum tube, after which it is again necessary to sort the stones and stack them into a package. Secondly, the method involves a heavy burden on the operating personnel due to the noise produced during the drum process, the formation of large amounts of dust, and the efforts in sorting and stacking the stones when they are ready. . Even when sorting and stacking the stones is done mechanically, manual assistance from the operating staff is required. Thirdly, it is not possible to drum stones of a relatively large size. A lot of breakage occurs, and a lot of waste is also formed. In addition, manually stacking relatively large stones is a very heavy and dangerous job.
    Despite the disadvantages, the drumming process is nevertheless applied in practice, because it has an important advantage that it can be achieved with this that an appearance of the stones can be obtained that is generally perceived as beautiful by the consumer. A natural aging image is obtained with drumming, as a result of which the appearance of used natural stone is actually approximated. That makes stones that are outdated through a drum process commercially interesting.
    As explained in the foregoing, traditional drumming is an inefficient method of production. This fact, combined with increasing price pressure, causes manufacturers to look for a solution where it is possible to age bricks in the production line, that is, a solution where the bricks can be moved from a previous station to an aging station and further on. without interfering with the mutual configuration of the bricks in such a way that repositioning of the bricks is necessary. The bricks are preferably subjected to a aging treatment when they are located between the drying chambers and the stacking machines. At that stage, the bricks are positioned in a single layer on a production board. Since the layers of stones are only stacked into packages after aging, this only takes place once in the production line.
    Aging methods have already been developed that are suitable for use in the production line as indicated above. A major disadvantage of this, however, is that the aging image that is obtained differs considerably from the traditional drum image. This is often caused by the absence of drum scratches on the surfaces of the stones, and because each stone looks similar (rehearsal).
    It is an object of the invention to provide a method for aging bricks, which is suitable for giving the bricks a naturally aged appearance, and that within the cycle time of a bricks producing machine, wherein it is not necessary to remove the bricks from the bricks. production line and rearrange after aging. The object of the invention is achieved by a method in which the bricks are placed in a device comprising a carrier with impact elements attached thereto, wherein the bricks and the carrier with the iris impact elements are moved back and forth with respect to each other and simultaneously are rotated relative to each other, and the impact elements are brought into contact with the stones.
    The use of impact elements that are brought into contact with the stones is known per se, for example from US 2006/0288658. According to the method known from this publication, use is made of a device comprising a carrier with impact elements attached thereto, wherein the impact elements can perform a swinging movement with respect to their fixing locations on the carrier. The device used further comprises a table for supporting the stones to be aged, and means for causing the table to vibrate. The table is arranged at a suitable distance below the impact elements so that when stones are passed over the table there may be contact between the impact elements and the stones. It is achieved through the vibrations of the table that the stones start to move, and as a result the impact elements start to move in such a way that the stones and the impact elements touch each other alternately and move away from each other again. Every time the stones and the impact elements touch each other, the surface of the stones, in particular an upper surface, an upper edge or a corner on the upper side of the stones, is damaged or a piece of the stones is knocked out so that an obsolete one appearance of the stones.
    With the method according to the invention, the relative movement of the stones and the impact elements is totally different than with the method known from US 2006/0288658. Namely, in the method according to the invention, the stones and the carrier with the impact elements are moved back and forth relative to each other and simultaneously rotated relative to each other. Surprisingly, it has been found that in this way a natural aging image is obtained, which comes across as authentic and is therefore highly desired by the consumer. The rotational movement in particular appears to be the reason for this, because it achieves that an impact direction on the stones is not along a straight line, so that the stones are hit from all possible angles and repetition of the appearance of the stones is prevented. It is thereby achieved that the stones are always beaten apart, so that edges and corners of the stones remain easily accessible and can therefore be hit more easily by the impact elements. For the sake of completeness, it is noted that assuming that a supporting surface of the stones extends in the horizontal direction, the reciprocating movement takes place in the horizontal plane, and also the rotational movement in the horizontal plane is carried out around a vertical rotation. -as.
    In addition to the advantage of the very good result of the aging process, the method according to the invention has the advantage that it offers the possibility of treating the stones while they are in the production line. In particular, it is possible that a single layer of bricks, which is located on a production board and which as such comes out of the drying chambers, is placed in the device comprising the carrier with the impact elements attached thereto, whereby the bricks can remain on the board. The aging process then takes place by moving the production board with the layer of stones and the carrier with the impact elements back and forth with respect to each other and simultaneously rotating it. The shelf with the obsolete stones can then be moved further, for example to a stacking machine where different layers of stones are stacked on top of each other.
    With great advantage, prior to bringing the impact elements and the stones into contact with each other, barriers are provided around the stones, preferably leaving a limited amount of free space between the barriers and the stones. For example, a closed frame can be applied, which is placed around the total set of stones, with play in the frame, on the basis of which a limited amount of movement of the stones in the frame is possible. As a result, on the one hand, the 'aging process' according to the invention can take place unhindered, while on the other hand it is ensured that the mutual configuration of the stones is retained. This means that it is not necessary to re-sort and position the stones afterwards. At most, the stones should be pushed against each other, for example by exerting pressure forces on two adjacent sides of the layer of stone.
    In a practical application of the method according to the invention, the combined relative movement of the bricks and the carrier with the impact elements is obtained by driving only the carrier with the impact elements to execute both the reciprocating movement and the rotational movement. feed. The plank on which the stones are placed can then remain in a fixed place. In this way, handling the stones in the production line is the easiest.
    The impact elements are preferably allowed to perform a swinging movement with respect to their attachment points on the carrier. The impact elements can for instance be blocks or spheres which are suspended from the carrier by means of a chain or the like. Such a construction leaves much freedom for movement of the impact elements, and contributes to the desired random character of the impacts of the impact elements on the stones.
    As can be deduced from the foregoing description of the method according to the invention, the device used herein comprises a space suitable for receiving the stones, a carrier with impact elements attached thereto, and drive means for effecting a relative movement of stones when they are included in the device and the carrier with the impact elements, wherein the drive means are adapted to move the stones and the carrier with the impact elements relative to each other and simultaneously rotate relative to each other .
    It has already been noted that it is advantageous if the combined relative movement of the stones and the carrier with the impact elements is realized by driving only the carrier with the impact elements to perform both the reciprocating movement and the rotational movement. . In particular, the device according to the invention can comprise a frame for supporting the carrier with the impact elements, wherein the carrier with the impact elements is arranged both linearly displaceable and rotatable relative to the frame, and wherein the drive means are arranged around the carrier to move back and forth with the impact elements and rotate at the same time.
    Preferably, the support with the impact elements is in vertical. movable in the vertical direction, so that it is possible both to temporarily create sufficient space under the impact elements for receiving a new quantity of bricks, and to bring the impact elements to a vertical position with respect to the bricks suitable for the aging process to be carried out.
    There are various possibilities to increase the extent to which the impacts of the impact elements on the stones have different effects. The device can for instance comprise impact elements of different nature, wherein properties of the impact elements such as material, shape, dimensions and weight can be different. It is also possible that the impact elements are positioned irregularly distributed over the carrier and / or that a level of the impact elements is different from a level of the support for a number of impact elements.
    . . The invention will be further elucidated with reference to the description below. Reference will be made herein to the drawing, in which like reference numerals indicate like or similar parts, and in which: figure 1 shows diagrammatically a perspective view of an embodiment of the device according to the invention, and of a board with a layer of stones thereon attached to the device to be fed, shows a board with a layer of bricks that is received in the device, and a board with a layer of bricks that has been moved further from the device after a treatment of the bricks in the device; Figure 2 shows diagrammatically a front view of the device and a shelf with a layer of stones included therein; figure 3 schematically shows a side view of the device and a shelf with a layer of stones included therein; and figure 4 schematically shows a top view of the device and a shelf with a layer of stones included therein.
    The figures schematically show an embodiment of the device 1 according to the invention, which is particularly adapted to be used for treating stones 2 in order to give the stones 2 an outdated appearance. In figure 1 a direction is indicated by means of an arrow in which stones 2 are supplied to the device 1.
    . The device 1 according to the invention comprises a frame 3, in which a shaking grate 4 is arranged movably in the horizontal direction. In the example shown, the shaking grate 4 is slidable over rollers 5 located on the frame 3. Below the shaking grate 4 there is a space 6 in which the stones 2, which are located on a shelf 7 in the example shown, can be received. In this space 6 there is also a rotatably arranged table 8 which serves to support and rotate the board 7 with the stones 2.
    A length and width of the shaking grate 4 is chosen to be larger than a diameter of a layer of bricks 2 to be treated. The shaking grate 4 is preferably height-adjustable.
    For the purpose of driving the shaking grate 4 and the table 8 during operation of the device 1, the device 1 comprises any suitable drive means 9. The drive means 9 comprise, for example, motors suspended in the frame 3, and suitable transmissions between an output shaft of the motors and the shaking grate 4 and the table 8 respectively. It is advantageous if the speed and the stroke of the reciprocating movement of the shaking grate 4 are adjustable or continuously variable, and if also the direction and speed of the rotation movement of the table 8 can be varied.
    Suspended elements 10 are suspended from the shaking grate 4, which serve to strike the bricks 2 to be aged and thus cause the required damage, and which are positioned distributed over the entire shaking grate 4. For the sake of clarity, only one single row of impact elements 10 is shown in each of the figures. The impact elements 10 can have different shapes, dimensions and weights, and can be made of different materials. Examples of suitable materials are steel, plastic and natural stone. Due to the differences, it is achieved that an impact of the impact elements 10 is arbitrary, whereby repetition in the appearance of the stones 2 is prevented. The individual impact elements 10 can be positioned at a different mutual distance, and can also be suspended at a different vertical distance relative to the stones 2 to be treated. There may possibly be a possibility to adjust the positioning of the impact elements 10, if desired, in order to adjust them optimally to the shape and dimensions of the stones 2 to be treated.
    In a preferred embodiment of the device 1 according to the invention (not shown), the shaking grate 4 is arranged in its entirety so as to be slidable and rotatable, wherein there is no need for provision for moving the board 7 with the bricks 2. In such a situation it is easier to have the aging treatment take place in the production line, wherein the board 7 with stones 2 can for instance be moved on a conveyor belt, which can then simply run under the device 1. In any case it is achieved on the basis of the rotational movement that a direction of the impact of the impact elements 10 on the stones 2 is never in a straight line, so that the stones 2 can be hit from all possible angles and repetition in the appearance of the stones 2 can be prevented. It is further achieved that the stones 2 are always beaten apart during the aging treatment. There is always room between the stones 2, so that the edges and corners of the stones 2 can be easily touched.
    All kinds of movements of the impact elements 10 can be effected with the shaking grate 4. Thus, during operation of the device 1, the impact elements 10 can make a striking movement, a dragging movement, or combinations of these movements. Instead of the shaking grate 4 as shown, other carriers 4 can also be used for the impact elements 10. For example, it is possible to use a round tube or a conveyor belt, where there may be a single direction of rotation. The carrier 4 as a whole can also be arranged so as to be movable both in vertical and in horizontal direction,
    Figure 4 shows a frame 11 for enclosing the layer of stones 2 with play. In each direction, a dimension of the frame 11 is greater than the sum of the dimensions of the individual stones 2 which are in a row in the relevant direction plus the sum of the spaces between the individual stones 2. Incidentally, these spaces arise during production of the stones 2 in that a form with partitions is used, which is later removed. Spaces then remain at the place of the partitions between the stones 2.
    The frame 11 applied during the aging treatment prevents the stones 2 from being knocked away. The frame 11 must be supplied from above or from a side and placed as soon as a layer of stones 2 has arrived under the shaking grate 4, and must recede once the aging treatment has ended.
    The frame 11 can be a fixed frame 11 per dimension of a specific layer of bricks 2, wherein for each type of layer an appropriate frame 11 can be chosen. However, it is also possible that the frame 11 is variably constructed, so that it can be adapted to different dimensions of the layers. The frame 11 can herein be formed by four beams which are adjustable relative to each other. Furthermore, the frame 11 can be designed with a grid that corresponds to the shape that is used during the production of the stones 2. The grid then serves to maintain the existing mutual distance of the stones 2 as they lie on the production board 7, so that the corners and edges of the stones 2 can be more easily hit by the impact elements 10.
    As has already been indicated in the foregoing, the stones 2 can be treated while they are lying on the production board 7, whereby the production board 7 with the stones 2 is passed under the device 1. In an existing situation, the device 1 can be placed over the transport line. It is also possible to treat the layer of bricks 2 when it is placed on a specially provided plate or specially provided feed-through means. In such a case, the device 1 is, for example, parallel to the existing line (by-pass). The stones 2 must then be taken from the production board 7 and be transferred to the plate or transit means. The stones 2 can be fed through per layer, or as a strand, the layers being pushed against each other. The possibility exists to design the plate or the feed-through means with a system for manipulating the location of the stones 2 in order to for example, to remove the corners and edges of the bricks 2 so that they can be more easily exposed to the impacts of the impact elements 10. This can then be adjustable per brick size.
    After an aging treatment of a quantity of bricks 2, dust and grit is removed from and between bricks 2 using suitable means such as an automatic roller broom, or a strong blower or vacuum cleaner. Subsequently, the layer of stones 2 is formed by joining two adjacent sides into a layer with flat sides, wherein the stones 2 abut each other, in order to be accommodated in a stack in this configuration. If the stones 2 do not lie on the production board 7, they must be transferred to the existing package label.
    In summary, the operation of the device 1 according to the invention is as follows. A layer of bricks 2 on a production board 7 is supplied from the drying chambers, via a bag lift, and arrives under the carrier 4 with impact elements .10. The frame 11 is placed on the production board 7 and encloses the stones 2 with play. The carrier 4 with impact elements 10 sinks vertically to a set height relative to the stones 2, whereafter a reciprocating movement and a rotational movement of the stones 2 and the carrier 4 with impact elements 10 is produced. The impact elements 10 strike on the stones 2, whereby pieces of the corners and edges are knocked off, and scratches are created on an upper surface of the stones 2. Especially as a result of. the rotational movement causes damage that resembles the natural aging that occurs with the conventional drumming of stones. Moreover, during the treatment, the stones 2 are constantly being moved back and forth within the frame 11, so that openings originally present between the stones 2 are retained, making it easier for the corners and edges of the stones 2 with the impact elements 10. To hit. If this effect did not occur, the stones 2 would come to lie against each other in one corner of the frame 11.
    After the processing has been completed, the frame 11 is lifted, and a next board 7 with bricks 2 is supplied. The board 7 with the treated stones 2 is pushed to a next station, where dust and grit are removed, and where the stones 2 are again formed into a layer with flat sides.
    It will be clear to a person skilled in the art that the scope of the invention is not limited to the examples discussed above, but that various variations and modifications thereof are possible without departing from the scope of the invention as defined in the appended claims.
    According to the invention, when treating stones 2 in order to give the stones 2 an outdated appearance, a device 1 comprising a carrier 4 with impact elements 10 attached thereto is used. The stones 2 and the carrier 4 with the impact elements 10 are moved back and forth with respect to each other and simultaneously rotated relative to each other, the impact elements 10 being brought into contact with the stones 2. This ensures that the impact elements 10 impact on the bricks 2, wherein, in particular as a result of the rotational movement, the nature of the impacts is random, so that a naturally aged appearance of the bricks 2 is obtained.
