    DEVICE FOR APPLYING FORM STONES IN A CERTAIN POSITIONING PATTERN ON A PALLET
    The invention relates to a device for applying shaping bricks to a particular positioning pattern on a pallet or other supporting means according to the preamble of claim 1.
    Forming bricks, for example form bricks from concrete, are used in a known manner for paving roads, streets, terrains, etc. The molding stones which in particular have a square shape, but can also have other shapes, are usually placed in a certain positioning pattern on a surface, that is to say a flat bed of sand or pebble. Known positional patterns are series relationships, diagonal relationships, patterns of a herringbone or patterns in which the longitudinal center lines of adjacent form stones are at right angles to each other.
    In order not to have to manually position molding bricks of this type in a difficult manner by hand, molding bricks positioning devices, also referred to as positioning tongs, are known. Such positioning tongs grasp an entire layer of shaping bricks from the shaping bricks usually supplied on pallets, transport the gripped layer of shaping bricks to the intended positioning location and deposit the shaping bricks there directly against each other on the surface. By using such positioning tongs, the positioning of the molding stones can be considerably accelerated and facilitated. A condition for the use of such positioning tongs, however, is that the shaping bricks to be grasped by the positioning tongs are arranged on the pallet, that is to say, directly adjacent to each other in a certain direction and arrangement.
    Used molding stones that are not supplied by the manufacturer, but are removed from existing roads, streets, etc., are usually disorganized in containers or stacks. If such shaping bricks are to be used again and positioned by means of positioning tongs, it is thus necessary to arrange the shaping bricks layerwise and in the same or similar manner, as is the case with new shaping bricks supplied on pallets from the manufacturer.
    In order not to have to perform this manually, a device according to the preamble of claim 1 for the formation of molding stones in a particular positioning pattern on a straightening table has already been developed in EP-0 256 1769 A1. Such devices include an insertion holder into which the molding stones can be inserted. From the insertion holder, the shaping bricks come on conveyor belts to an area for inspection in order to subsequently deposit them in a predetermined position and direction in series on a straightening table by means of a depositing device. From there, the deposited series of shaping bricks is moved further on the laying table by means of a sliding device, until the individual shaping bricks abut against a stop profile. In this moving operation, the shaping stones are brought into the desired positioning pattern, in particular a herringbone pattern. Following series of shaping bricks are moved by the moving device against the last of the shaping bricks located on the straightening table. The stop profile is thereby moved stepwise in the direction of displacement relative to the straightening table.
    EP-1,600,556A2 discloses a device in which the shaping stones are deposited as series on a straightening table in the form of a conveyor belt which moves under a wedge-shaped stop profile. The molding stones carried by the conveyor belt are thereby pressed against the stop profile and are aligned correspondingly with the circumference of the stop surface. After each set of molded bricks, the stop profile is moved back step by step to a certain degree.
    A further device for arranging molding stones in the pattern of a herringbone is disclosed in WO-03 / 104566A1. Here, wedge-shaped stop profiles are also used for aligning the molding stones.
    It is an object of the invention to provide a device of the above-mentioned type which is assembled as simply as possible and which enables a high power and an accurate close fitting of the molding stones within the layer of molding stones.
    This object is achieved according to the invention by a device with the features of claim 1. Advantageous embodiments of the invention are formulated in the subclaims.
    In the device according to the invention, the aligning table, together with the stop device attached to the aligning table, is displaceable relative to the depositing device in the direction of the displacement of the molding bricks, and by pressing a following series of molding bricks against a series of shaping bricks already in the end position shifted in the direction of displacement.
    For the invention it is thus characteristic that the series of shaping stones deposited on the straightening table are displaced on the straightening table, wherein the respective following series of shaping stones is pressed against the series of shaping stones which are already present in their end position on the straightening table. As a result, the individual sets of molding stones are placed close to each other within the layer of molding stones. Furthermore, the compressive force by means of which the series of shaping bricks are pushed against each other is also used to move the aligning table over a certain distance in the direction of moving the shaping bricks. This distance corresponds in particular to the width of shaping bricks, measured in the direction of displacement. As a result, the displacement device must always travel the same distance for each series of shaping stones, irrespective of how many sets of shaping stones are already located within a layer of shaping stones in their end position. The device can therefore be designed in a simple manner. Furthermore, the distance of the displacement can be optimized, which makes high power possible. A relatively simple construction of the device is made possible when the displacement device comprises an element carrier of the displacement extending transversely to the direction of displacement, to which the displacement elements are attached. By moving the element carrier from moving, all moving elements are thereby simultaneously shifted together.
    In the case of bonding of form bricks where the form bricks must be arranged within a layer of form bricks in different directions, for example with patterns of a herringbone, it is advantageous if the moving elements can be displaced transversely to the direction of movement of the form bricks such that they the deposited molding stones can optionally be brought into contact in the region of one half of the molding stones or in the region of the other half of the molding stones. In particular, it is possible in this way to direct the molding bricks in a certain series of molding bricks at an angle of + 45 ° with respect to the direction of movement, while the molding bricks of the following series of molding bricks are angled at -45 ° relative to the direction of movement. direction of movement.
    According to an advantageous embodiment, the moving elements each comprise two wedge-shaped moving surfaces. Each time according to which of the two moving surfaces comes into contact with the added molding stone, the molding stone is rotated in one direction or the other.
    The aligning table is advantageously coupled to a drive of the table which can be brought into a free floating position upon contact of a following series of shaping bricks with a series of shaping bricks located in the end position. Such a drive of the table can thus be used on the one hand to return the straightening table to its initial position when a completed layer of shaping bricks has to be removed from the straightening table, while the drive of the table on the other hand in the opposite direction, i.e., in the opposite direction. the direction of moving the shaping bricks produces no driving force and is only used to limit the distance of moving the aligning table to a predetermined amount.
    Advantageously, the stop elements arranged in the straightening table can be moved via a pivoting or moving mechanism between a stop position in which they limit the movement of the shaping stones on the straightening table and a releasing position in which they are positioned above or below those arranged on the straightening table. form blocks. With the aid of such a pivoting or displacing mechanism, the stop elements can be brought in a simple manner into a position in which they do not hinder the return of the straightening table to its original position after the completion of a layer of shaping bricks.
    Advantageously, a fixing device of the layers of shaping bricks is provided for fixing the finished layer of shaping bricks arranged on the aligning table, wherein the aligning table can be moved relative to the fixed layer of shaping bricks in an original position, in which the aligning table is located next to this layer of shaping bricks, so that the completed layer of shaping bricks can be placed on a pallet or other supporting means positioned below it. In particular, the fixing device of the layers of shaping bricks may comprise a transverse support to be fixed to a frame of the table with abutment elements, against which the finished layer of shaping bricks can be moved by means of the moving device in order to move the layer of shaping bricks between the fixing device of the layers of shaping bricks and the moving device. Such a fixing device of the layers of shaping bricks ensures that the finished layer of shaping bricks is held together, while the target table is pulled away beneath the finished layer of shaping bricks in order to subsequently deposit this layer of shaping bricks on, for example, a pallet located below.
    The invention is further illustrated by way of example with reference to the drawings. Here: Figure 1 shows an image obliquely from above of the part of the device according to the invention which is important according to the present invention, some parts of which are schematically shown or omitted for simplification; figure 2 shows a top view of the device of figure 1, with a slightly longer part of the transport device and a pallet, and figures 3-9 show an image obliquely from above of the device according to the invention when applying molding bricks in a pattern of a herringbone on a target table in different stages of the process.
    Figures 1 and 2 show a device for arranging molding stones 1 in a certain positioning pattern, in the present case in a pattern of a herringbone, on a pallet 2 or another, in particular transportable, support means.
    As can be seen in particular in Figure 2, the device comprises a conveying device 3 for serially conveying the molding bricks 1 to an output 4 of a conveying device. In the present case the conveyor device 3 is a conveyor belt with side parts 3a, 3b of the conveyor belt which are arranged at an angle of 90 ° and upwardly apart with respect to each other, as in Figure 2 on the basis of the part of the conveyor belt shown to the right is indicated. The square shaping bricks 1 are thus supplied with their longitudinal sides downwards or upwards, respectively, to the conveyor belt. The position of the angle of the further parts of the conveyor belt is changed in the direction of the exit 4 of the conveyor in an increasing manner such that the shaping stones 1 are arranged in a horizontal plane in the area of the exit 4 of the conveyor. that is, the two large surfaces of the molding bricks 1 lie in horizontal planes.
    Only a final part of the transport device 3 is shown in Figure 2. At the other end, not shown, the conveying device 3 is filled with shaping bricks 1 such that the shaping bricks 1 lie one after the other, i.e. serially, on the conveying apparatus 3. The filling can for instance take place under a collecting container in which the shaping stones 1 are arranged in an orderly manner in order to be supplied to the transport device 3 by means of a removal device similar to a scraping over the bottom.
    Further, in the area of the parts of the conveyor device 3 (not shown) additional processing stations (not shown) are provided for aligning, measuring and possibly sorting non-usable shaping bricks 1.
    The entire device shown in Figures 1 and 2 including the entire conveyor device 3, the collecting container for shaping bricks and additional processing stations can be mounted on a truck or trailer in order to form a movable installation that can be brought to different construction sites. However, the construction as a fixed device is also possible.
    Connected to the output 4 of the transport device is a depositing device 6 arranged in line with respect to the transport device 3, which is shown only diagrammatically in the figures. In the exemplary embodiment shown, the depositing device 6 comprises five pairs of retaining jaws 7 which are arranged linearly behind each other at a certain mutual distance. The pairs of retaining jaws 7 each comprise two parallel, spaced apart retaining jaws 7a, 7b. In the exemplary embodiment shown, the retaining jaws 7a, 7b consist of short conveyor belts whose deflection rollers are rotatable about substantially vertical axes. The length of these short belt conveyors corresponds to approximately the length of the molding bricks 1. Furthermore, the holding jaws 7a, 7b and short conveyor belts of a pair of tongs similar to the tongs can be opened and closed and spaced apart such that the molding bricks 1 can come between the holding jaws 7a, 7b, the holding jaws 7a, 7b abutting against the opposite side surfaces of the molding bricks 1 with a certain prestress.
    In the exemplary embodiment shown, five pairs of retaining jaws 7 are arranged one behind the other and at a predetermined distance, the drives of which can be controlled independently of each other. These five pairs of retaining jaws 7 operate in such a way that a series of shaping bricks 1 is fixed in a predetermined position and can then be delivered together on a straightening table 8. In the embodiment shown, this series of shaping stones 1 consists of four shaping stones 1. The number of pairs of retaining jaws 7 is one greater than the number of shaping stones 1 in a series. However, the distance between the individual pairs of retaining jaws 7 is considerably smaller than the length of a molding block 1, so that the molding blocks 1 can be transported from a pair of retaining jaws 7 to the next pair of retaining jaws 7 when the short conveyor belts are switched on.
    When filling the empty depositing device 6, all pairs of retaining jaws 7 are initially switched on, i.e. the short conveyor belts rotate in the conveying direction. If a first molding brick 1 comes from the transport device 3 to the exit 4 of the transport device and from there into the depositing device 6, the pair of retaining jaws 7 furthest to the right initially grips here, which is the fifth pair of retaining jaws 7 here. is indicated, the mold brick 1 and transports it to the following pairs of retaining jaws 7, until the first mold brick 1 is in a predetermined position between the first pair of retaining jaws 7, which in Figure 2 is furthest to the left. In this position, the drive of the two short belt conveyors switches off the first pair of retaining jaws 7, while the heat transfer belts from the second to the fifth pairs of retaining jaws 7 move further. The next molding brick 1, which comes in the area of the depositing device 6, is further transported to the second pair of retaining jaws 7. The short conveyor belts of the second pair of retaining jaws are switched off when the second molding brick 1 is in the predetermined position between the retaining jaws 7a 7b of the second pair of retaining jaws 7, while the third to fifth pairs of retaining jaws move further, and so on. In this way, four form bricks 1 are sequentially fixed in a straight series at a predetermined distance from each other and in a predetermined relative position with respect to the underlying straightening table 8 between the first to the fourth pairs of retaining jaws 7, as shown in figure 2. The fixed series of forming stones is initially still at a certain distance above the straightening table 8 at the same height as the exit 4 of the transport device.
    The straightening table 8 comprises a flat rectangular plate of in particular steel. The aligning table 8 serves to move the individual sets of shaping bricks 1, which are deposited on the aligning table by the depositing device, by means of a moving device 9 and thereby to align in a desired manner in order to form a layer of shaping bricks with a specific positioning pattern. as shown in Figure 7.
    As is particularly shown in Figure 1, the straightening table 8 is movably supported on the edge side on two parallel guide rails 11 which form part of the frame of the table. Only horizontal frame elements 12 of this frame of the table are shown. The window elements 12 and the guide rails 11 extend at a right angle with respect to the longitudinal direction of the depositing device 6. The aligning table 8 can thus be moved in a horizontal plane transversely to the depositing device 6, wherein it extends below the depositing device 6. Between the window elements 12 there is a free space 13 that is wider than the length of the depositing device 6 and therefore wider than the length of a series of shaping bricks.
    The straightening table 8 can be moved by means of a drive device (not shown in more detail), in particular by means of one or a plurality of hydraulic cylinders, into a pushed back starting position which is shown in figures 1 and 2. The drive device is on the one hand on the straightening table 8 and on the other hand attached to the table frame. In this pushed back starting position, the front end 14 of the straightening table 8 is relatively close and below the front series of the holding jaws 7b. The rear end 15 of the straightening table 8, on the other hand, protrudes a larger part rearward beyond the rear series of retaining jaws 7a.
    In the front end region of the straightening table 8, a stop device 16 is mounted which is moved together with the straightening table 8. This stop device 16 comprises a tubular carrier 17 of the stop element which extends over the entire width of the straightening table 8. The carrier 17 of the stop element is pivotable at the end on the side by means of pivoting levers 18 about pivot axes 19 on bearing plates 20 of the aligning table 8. The pivoting axes 19 run horizontally and parallel to the depositing device 6, that is, transversely to the direction 21 of moving the aligning table 8.
    Along the stop element carrier 17 a plurality, in the illustrated exemplary embodiment of six, stop elements 22 are fixed at a predetermined distance from each other. The stop elements 22 comprise a triangular plate which is located in a horizontal plane and in a predetermined distance above the table plate 23 of the straightening table 8. The attachment of the stop elements 22 to the stop element carrier 17 takes place by means of vertical ribs extending from the relevant stop element 22 up to the stop element carrier 17.
    By means of pivoting cylinders 24 on both sides, of which only the piston rod is shown in Figure 1, the stop element carriers 17 and thus the stop elements 22 can be positioned between the lowered position shown in Figure 1, in which the stop elements 22 are situated at a distance from the table plate 23. which corresponds to approximately half the height of a brick of the molding bricks 1, and an elevated position is pivoted in which the stop elements 22 are located at a distance above the layer of molding bricks 10 directed at the target table 8.
    The shape of the stop elements 22 depends on the positioning pattern in which the shape stones 1 are to be arranged on the straightening table 8. In the exemplary embodiment shown, the stop elements 22 in the plan view of Figure 2 are triangular or wedge-shaped, with the points towards the lower end 15 of the Targeting table 8 are oriented. Both sides of the triangle are formed by stop surfaces 22a, 22b that form a right angle to each other. The stop surface 22a forms an angle of -45 ° with respect to the direction 21 of the displacement, while the stop surface 22b forms an angle of + 45 ° with respect to the direction of the displacement 21. As will be explained in more detail below, the shaping bricks 1 of a first series of shaping bricks deposited on the aligning table 8 by the depositing device 6 are displaced with respect to the stop elements 22, as shown in Fig. 2 on the basis of a first shaping brick that the displaced first shape brick 1 is shown with broken lines. In this displaced position, the displaced forming stones 1 of the first series of forming stones with a side surface abut against the abutment surface 22a, while these abut against the abutment surface 22b of the adjacent abutment element 22 with a head surface. The shaping bricks 1 of the first series of shaping bricks are therefore in the embodiment shown at an angle of -45 ° with respect to the direction 21 of the displacement. The shaping bricks 1 of a second series of shaping bricks, which consists of the following four shaping bricks 1, on the other hand, as explained later, are directed by the moving device 9 at an angle of + 45 ° to the direction of the moving 21 and with a side surface is laid on the abutment surface 22b, while a head surface abuts on the rear side surface of the molding stones 1 of the first series of molding stones.
    The shape of the stop elements 22 depends on the positioning pattern and may vary accordingly. In the case of a series relationship, the individual stop elements 22 can also be replaced by a continuous stop, which can for instance take the form of the stop element carrier 17.
    The displacement of the series of shaping stones deposited on the straightening table 8 takes place by means of the moving device 9. The moving device 9 comprises a carrier-like carrier 25 which extends above the straightening table 8 over the entire width and by means of end pieces 26 on both sides in the direction 21 of the displacement is movably guided on the window elements 12. The moving device 9 can herein be moved independently of the straightening table 8 and thus relative to it. The displacement of the displacing device 9 takes place via a drive device which in the embodiment shown comprises two hydraulic cylinders 27 which are arranged in the area of the window elements 12. As shown in Figure 1, the hydraulic cylinders 27 are supported with their front end on support feet 28 which are arranged at the front end of the window elements 12. At the other end, the relatively long hydraulic cylinders 27 are attached to the end pieces 26 of the moving device 9 by means of the piston rod thereof. By means of the hydraulic cylinders 27, the displacing device 9 can thus be moved relative to the aligning table 8 in order to displace a set of molded bricks deposited on the aligning table and thereby direct it in the desired direction.
    For this purpose, the moving device 9 comprises a carrier 29 of the moving element to which a predetermined number of moving elements 30, in the exemplary embodiment five, are attached. The carrier 29 of the moving elements, together with the moving elements 30, is movably guided in the transverse direction, i.e. in the direction of the arrow 31, to the carrier 25. This transverse displacement takes place via a moving drive which in the embodiment shown is designed as a hydraulic cylinder 32. The hydraulic cylinder 32 is supported at one end on an end piece 26, while the opposite end of its piston rod is attached to the carrier 29 of the moving element. Because of this being displaceable transversely, the position of the displacing elements 30 can be varied transversely with respect to the direction 21 of the displacement in a predetermined extent.
    The moving elements 30 again comprise triangular or wedge-shaped plates in top view, the point of which is directed forwards, i.e. in the direction of the front end 14 of the straightening table 8 or in the direction of the stop elements 22, respectively. Furthermore, each moving element 30 comprises moving surfaces 30a, 30b arranged at right angles to each other. The moving elements 30 are arranged at a distance above the table plate 23 which corresponds to approximately half the height of the molding stones 1. Furthermore, the moving device 9 is constructed so low that it can move underneath the depositing device 6 when it is located in the the raised position shown in figure 1, in which the shaping stones 1 are received by the transport device 3.
    The position of the moving elements 30 transversely with respect to the aligning table 8 is adjusted such that the points of the moving elements 30 or on the left or the right half of the molding bricks 1 engage, whereby the molding bricks in predetermined directions be pivoted, as explained below.
    It is further noted in Figures 1 and 2 that a fixed fixing device 33 of the layers of molding stones is provided in the front end region of the window elements 12. This fixing device 33 of the layers of shaping bricks serves to clamp a finished layer of shaping bricks 10 placed on the aligning table together with the moving device 9 and thereby fixes it in order to subsequently be able to pull away the aligning table 8 backwards under the completed layer of shaping bricks 10 without that the closely adjacent relationship of molding bricks 1 comes loose.
    The fixing device 33 of the layers of shaping bricks comprises a transverse support 34 which can be hung on both ends in holding plates 35 and can be fixed, which are fixed to the frame elements 12. The holding plates 35 are in each case directed at the top edge to a series of locking recesses 36 in which the cross beams 34 can be hung. As a result, the longitudinal position of the fixing device 33 of the layers of shaping bricks can be varied on the window elements 12 in a simple manner.
    The fixing device 33 of the layers of shaping bricks furthermore comprises five abutment elements 37 which are mounted side by side on the transverse support 34. The abutment elements 37 are again triangular or wedge-shaped, the points facing the depositing device 6. Each abutment element 37 has two abutment surfaces 37a, 37b arranged at right angles to one another in the same manner as the abutment elements 22 of the abutment device 16. The abutment elements 37 lie in a horizontal plane and are arranged in height such that they come to lie close to the abutment elements 22 when the abutment device 16 together with the aligning table 8 has been moved further forward enough and the abutment elements 22 are still located in the lowered position. The position of the abutment elements 37 transversely with respect to the aligning table 8 is precisely the same as that of the abutment elements 22. If the aligning table 8 is in its most forward position, the abutment elements 37 come accurately below the abutment elements 22 and take the order from supporting over layers of shaping bricks 10 completed for the two first series, so that the stop element carrier 14 together with the stop elements 22 can be pivoted up without compromising the firm combination of the bricks. This pivoting up of the stop elements 22 is necessary in order to be able to move the aligning table 8 together with the stop device 16 back to the original position shown in Figs. 8 and 2 after the layer of shaping bricks 10 without the stop elements 22 taking along the layer of shaping bricks 10 .
    If the aligning table 8 is in the pushed back original position, the completed layer of forming stones 10 initially clamped between the moving device 9 and the fixing device 33 of the layers of shaping bricks can be placed through the free space 13 on the pallet 2 arranged closely below it . This placing takes place advantageously in that the moving device 9 is moved back to its original position, which causes the finished layer of shaping stones 10 to fall down on the pallet 2. Since the distance of the falling is a minimum here, for example only a half centimeter to 2 cm, the dense connection of the molding stones does not come loose.
    The method of operating the device according to the invention is further illustrated with reference to Figures 2-9.
    In Figure 2, which shows an original position, the straightening table 8 is in the rear position. The stop device 16 arranged at the front end 14 of the straightening table 8 is in the lowered position in which the stop elements 22 are arranged half a height of the stones above the table plate 23. Furthermore, the stop elements 22 are located close to the depositing device 6. The displacing device 9 is also in its rear position in which the displacing elements 30 are arranged close to and behind the depositing device 6. The pallet 2 arranged on a table for lifting not shown is located in the free space 13 in front of the straightening table 8, the abutment elements 37 of the fixing device 33 of the layers of shaping stones being located above the front end of the pallet 2.
    The depositing device 6 is in a swiveled up position at the same height as the exit 4 of the conveying device. Four shaping stones 1 are fixed in the first four pairs of retaining jaws 7. These four molding stones 1 form a first series of molding stones. The fifth pair of retaining jaws 7 remains unused with the first series of molding stones.
    Starting from this, the depositing device 6 together with the four forming stones 1 is initially lowered such that the four forming stones 1 come to lie on the straightening table 8 in a straight series. The pairs of retaining jaws 7 are then opened, whereby they are pivoted slightly apart. Subsequently, the empty depositing device 6 is pivoted upwards again in the original position in which it is located at a small distance above the deposited molding bricks 1. The depositing device 6 is then again ready for receiving a next series of molding bricks 1 and can conveyor device 3 can be filled correspondingly. In the second series of shaping stones, however, not the first to the fourth pairs of retaining jaws 7, but the second to the fifth pairs of retaining jaws 7 are used. As shown in Figures 2 and 3, after depositing the first series of shaping stones on the straightening table 8, the moving device 9 is moved forward in the direction 21 of the moving. As can be seen in Figure 2, the triangular displacing elements 30 are oriented relative to the deposited molding stones 1 such that the points of the displacing elements 30 in each case touch a deposited molding stone 1 in the left half of the molding stone when the displacing device 9 is moved forward. The shaping bricks 1 are thereby rotated counterclockwise and, as the moving elements 30 are moved further forward, directed such that a longitudinal side of each shaping stone abuts the surface 30b of the moving element, while the end surface of the shaping bricks 1 is at the surface 30a of the moving element of the right-hand moving element 30 abuts. The shaping bricks 1 are moved and rotated by the moving elements 30 in the manner shown by the arrow 38 and thereby directed at an angle of -45 ° with respect to the direction 21 of the moving. Moving the shaping bricks 1 on the straightening table 8 takes place so long that the shaping bricks 1 abut the abutment elements 22 of the stop device 16, as shown with broken lines on the first shaping bricks 1.
    Figure 3 shows the moving device 9 when placing the first series of shaping bricks on the stop elements 22. Shortly before the shaping bricks 1 of the first series of shaping stones are placed against the stop elements 22, the (not shown) hydraulic cylinder which serves only for the later moving the straightening table 8 back into its initial position, being released in a floating position. For placing the shaping bricks 1 against the stop elements 22, therefore, the entire straightening table 8 is moved slightly forward via the shaping bricks 1 by means of the moving device 9. However, the free displacement of the straightening table 8 is blocked again a short time later, with the hydraulic cylinder of the straightening table being switched from its floating position into a blocking position. This switching takes place when the straightening table 8 has traveled a distance which corresponds to the width of a shaping brick 1, viewed in the direction 21 of the displacement.
    As Figure 4 shows, the displacing device 9 is then moved back to the original position in the rear, in which the displacing elements 30 are located behind the next second series of forming stones. In this rear original position, the carrier 29 of the moving element is then moved together with the moving elements 30 in the transverse direction, i.e. in the direction of the arrow 39, with respect to the portal-like carrier 25, until the moving elements 30 of the second series of forming stones arranged in the depositing device 6 in a position in which the points of the moving elements 30 touch the right half of the forming stones 1 of the second series of forming stones when they are on the target table 8 and the moving device 9 is then moved forward again. The shaping bricks 1 of the second series of shaping bricks are thereby rotated clockwise by + 45 ° with respect to the direction 21 of the displacement and subsequently forwarded by the moving device 9 against the first series of shaping bricks and against the stop surfaces 22b of the stop elements 22 are pressed, as is shown in figure 5. In this pressing action, the hydraulic cylinder of the straightening table is again switched to a floating position for a short time, so that the straightening table 8 is pressed via the pressed forming blocks 1 by means of the moving device 1 is moved forward with a width of a molding brick. The hydraulic cylinder of the straightening table is then switched to the blocking position again.
    Figure 5 shows the moving device 9 when pressing the second series of shaping bricks through an angle of + 45 °. During this driving operation, the raised depositing device 6 can already be possessed by a third series of shaping bricks. Figure 5 shows the third series of shaping stones between the pairs of retaining jaws 7 not yet in their end position.
    As shown in Figure 6, the moving device 9 is moved back again to its original position after the second series of shaping bricks have been pressed. In the meantime, the depositing device 6 is again occupied with four molding bricks 1, the third series of bricks taking the same position as the first series of bricks shown in FIG. The carrier 29 of the moving element together with the moving elements 30 is moved to the left in the transverse direction in the direction of the arrow 40. The moving elements 30 thus occupy the same position with respect to the third series of shaping bricks as with respect to the first series of shaping bricks. When subsequently moving as an action by the moving device 9, the forming stones 1 of the third series of forming stones are therefore again oriented and displaced in the same manner as the first series of forming stones.
    The described operations are repeated so many times until a complete layer of shaping bricks 10 with the desired number of rows of shaping bricks is present on the aligning table 8. This situation is shown in Figure 7. Because every time when a series of shaping bricks is moved by the moving device 9 against the directed string of shaping bricks already in the end position, all shaping bricks 1 of the layer of shaping bricks 10 are always pressed close together again, so that a very close relationship is formed .
    It can further be seen in Figure 7 that by repeatedly moving the entire aligning table 8 forwards, the stop elements 22 of the stop device 16 attached to the aligning table 8 cover the fixed abutment elements 37 secured to the frame elements 12 when the displacing device 9 presses the last series of shaping bricks from the shaping bricks layer 10. The completed layer of shaping stones 10 is therefore finally supported by the abutment elements 37. The stop elements 22 attached to the straightening table 8 vary the function of supporting this and can be pivoted upwardly from the area of the layer of shaping stones 10. It can be seen in Figure 8 that the straightening table 8 is subsequently moved back into the original position after the moving device 9. The straightening table 8 is thereby pulled away underneath the completed layer of shaping bricks 10. Then the clamping between the moving device 9 and the fixing device 33 of the layers of shaping bricks is broken, whereby also the moving device 9 is moved back to its original rear position, as is 9, the finished layer of shaping bricks 10 falls through the free space 13 onto the pallet 2 arranged directly below, not shown in FIG. 9, maintaining the close relationship of shaping bricks. Subsequently, in the direction of lifting on which the pallet 2 is located, the pallet is lowered by a degree corresponding to the height of a layer of shaping bricks 10. The device is then again in the original position shown in Figure 2 and is for shaping of a second layer of shaping bricks 10 which, after completion, is deposited on the first layer of shaping bricks 10 already on the pallet.
    A multitude of variations is possible within the scope of the invention. The depositing device 6 may comprise, instead of short conveyor belts, transporting and holding devices by means of which a series of shaping bricks 1 are initially positioned one behind the other above the aligning table 8 and can subsequently be deposited thereon. Triangular moving elements 30, abutment elements 22 and abutment elements 37 are then effective when the shaping bricks 1 on the aligning table 8 are not only displaced but must also be turned, as is particularly the case with herringbone patterns. If the turning of the shaping bricks 1 is not necessary, then corresponding elements can also be used with abutment surfaces which are at right angles to the direction 21 of the displacement. Instead of hydraulic cylinders, other drives can also be used, for example mechanical, electrical or pneumatic drives.
