Description

Apparatus and method for the artificial aging of stones

The invention relates to a device for the artificial aging of stones according to the preamble of claim 1. The invention also relates to a method for the artificial aging of stones according to the preamble of claim 20.

Walls, especially for landscape architecture are preferably prepared from natural or artificial stones, which are provided on the visible side with an irregular surface relief structure and / or rounded edges, as are formed, for example, by manually hewing Na ^¬ tursteinen.

Also known is the use of split stones, preferably made of concrete. A splitter to this situation, be led to ^¬ where the rough stones are cut in half, preferably from the stone production originating raw stones. The resulting split stones are often referred to as split rocks. Due to the division process on the side at which they were broken, these split stones have an irregular relief surface structure. From DE 22 06 732 a method and apparatus for splitting artificial stone blanks is known. Furthermore, from DE 33 32 041 AI and DE 33 47 077 AI devices for producing embossed splits known. Frequently, the split bricks, whether they are made of concrete or split natural stones, are required to have no sharp edges. Regardless, often a further treatment of the broken structure is desired. From the general state of the art, devices for aging stones are known. Reference is made, for example, to EP 1 699 609 B1. In addition, a large number of other methods for aging stones are known from the general state of the art.

On aging of stones, especially if this is to split stones, there is the problem that the work surface of the stone, that is not usually forms the later visible side of the stone, after leaving the Pro ^¬ production the top of the stone , In the so-called gap ^¬ stones, this follows from the fact that they are usually formed from a rough stone or block in that said block is split into two halves. Such cleavage methods are known from the general state of the art z. B. from DE 22 06 732 well known.

By splitting the ingot into two split stones, it follows that the gap surfaces of the resulting stones are laterally arranged and aligned with each other.

To edit the resulting by the column surface or to generally stones whose surface to be machined is aligned since ^¬ Lich, edit, two different ^¬ coherent methods are known. One way is to employ Al ^¬ esterification process, the ER is a side processing of the stones by means of corresponding processing tools possible. However, such methods are expensive and not efficient. This is z. B. known to attach to a ro ^¬ tierenden roller chain racket, which beat on the side surface of the stone. Added in cleft stones is that the stones with the aligned fractured surfaces must first from each other spatially so far separated that the processing tools can attack all over ^¬. The second way to continue processing ^¬ or aging of lateral surfaces of stones is to this by means of appropriate gripping tools to annul ^¬ and thus settle in that the surface to be processed forms the top side of the stone.

The lifting and repositioning of stones has the disadvantage that this is expensive, prone to failure and time-consuming. On the other hand, however, this allows the use of effek ^¬ tive and known aging processes, which act on the surface of stones. From the general state of the art, a variety of aging processes are known which act on the surface of the stones. A particularly suitable process results from EP 1 699 609 B1.

It must be at the stones which are ^¬ be working on a side surface which extends by 90 ° ge ^¬ tends in the erected or laid condition of the stone against the top side of the stone, not necessarily have to be split blocks. It may also be beneficial for other bricks where a side surface later forms the visible surface when it is aged. Again, the problem is that the laterally aligned side of the stone, which later forms the visible side of the stone, not with the Top of the stone coincides and therefore can not be aged as ef ^¬ fektiv, as is possible with the top of the stone.

The present invention has for its object to provide an apparatus and a method for aging stones, in particular split stones, which makes it possible to age stones quickly, inexpensively, effectively and reliably.

This object is achieved with respect to the Vorrich ^¬ tion by claim 1. This object is achieved according to Inventive ^¬ respect to the method by claim 20th

Because the inventive device for künstli ^¬ chen aging of stones, in particular concrete stones, tile clinkers, and natural stones comprises a support to which the stones are such placeable that too machining ^¬ tend side surface of the stone based laterally aligned on an upper surface of the stone is and runs substantially plane-parallel to a stop surface, the stones can, without the need for repositioning or turning is necessary to be processed in the situation in which they regularly leave the Pro ^¬ production. Furthermore, the stones are regularly packed in this location, delivered and then installed or relocated on the site. The retention of the La ^¬ ge or the orientation is particularly important in so-called split bricks, in which the gap surface forms the later visible side of the stone. This is usually aligned since ^¬ Lich. Such stones are, especially when it comes to concrete blocks by a splitting knife so cleaved that the cleavage surfaces of the resulting stones are arranged laterally and aligned. Until ^¬ long it was necessary when an effective aging process for aging stones, the gap should be selected to establish the gap ^¬ stones, so that the gap area forms the top side of the stone. After the aging process, the stones then had to be ^tipped back into their original position, since the stones are regularly installed in this orientation, in particular because walls are typically created with such stones. The Vorrich ^¬ tion according to the invention now avoids the complex process of double tilting of the stones.

This is made possible by the fact that a Vibrationseinrich ^¬ device is provided to set the pad on which the stones rest in such a way that due to the movement of the pad on the pad on ^¬ lying stone in the direction of the stop surface and moves away from this and the machined side surface of the stone thereby abuts against the stop surface, that the stop surface acts on the side surface of the stone aging.

By a suitable size of vibration, a ge ^¬ wünschter aging process can be achieved without have that other dimension took ^¬ necessary. By the vibration of an unre ^¬ lar movement of the stones is obtained with respect to the stop surface, so that a desired irregular aging ^¬ image is formed on the side surfaces of the stones. This is a decisive advantage of the device according to the invention, since aged stones are not artificially processed but natuer aged ^¬ Lich look.

Surprisingly, the inventor has found that the solution according to the invention results in rapid and effective aging of the sides of the stones intended for aging.

The strength of the movement of the stones is due to the vibration as well as the number of stones and their weight. The accidental striking of the aging side surfaces of the stop surfaces creates an appearance that corresponds to that of a naturally aged stone.

It is advantageous if the stone is a split stone and the side surface to be aged is the gap surface of the stone.

It is advantageous if the stones receive a horizontally acting component of motion substantially, particularly preferably exclusively, by the vibration ^device . Advantageous it is if the vibration device produces a movement such that the stone is substantially perpendicular to the surface of the stone to aging side ^¬ be moved. As a result, the vibration energy can be converted into a striking energy between the aging side surface of the stone and the stop surface particularly well.

It is advantageous if the pad is moved in a horizontal plane, preferably substantially transversely or at right angles to the passage direction / conveying direction of the stones back and forth or vibrates accordingly. Preferably provided that the feed of the stones through the aging area or on or with the pad in a horizontal plane takes place.

In an advantageous embodiment of the invention can be provided that the vibration device generates such a vibration that the vibratory movement of the stone composed of a primary and a secondary component of movement, the stone moves due to the primary component of movement perpendicular to the aging side surface of the stone , while the secondary BEWE ^¬ supply the stone component, based on the support, is moved upward.

Due to the two components of motion of the stone is obtained on the one hand the necessary impact energy (primary Bewegungskom ^¬ component) so that the side surface of the at Aging sti ^¬ nes abuts against the stop surface. On the other hand by the secondary component of movement, through which the stone from the base moved up and repelled and falls back due to gravity, achieved been an improvement ^¬ tion of the aging image, since the collision between the to aging side wall and the stop surface beliebi ^¬ ger becomes.

It may be advantageous if the pad moves so be ^¬ that the stones, based on the pad 1, are also pushed up.

It is advantageous if the primary movement component generated by the vibration device at least twice, preferably at least three times as large as the sekundä ^¬ re movement component. Characterized in that the Vibrationseinrich ^¬ tung the stone, at least twice as high, preferably three times as much moved in the direction of the primary component of movement, a high impact energy is achieved, that is, a large proportion of the vibration energy is converted into an impact ^¬ movement, while a significantly smaller Part of the vibration energy is used to lift the stone upwards.

It is advantageous if the vibration device is arranged so that a vibration is generated, which acts at an angle of 90 degrees to a direction of passage of the stones through the aging area. That is, the vibrating means generates, based on the stone, no, at least no we ^¬ sentliche vibration movement in the direction of passage to the front or to the rear, but only a movement in a plane which is at an angle of 90 degrees to the direction of passage of the stones. The direction of movement within this plane preferably results from the primary and the secondary components of motion or is composed by them.

It is advantageous if the vibration device is arranged parallel to a passage direction of the stones through the aging area laterally on the base. By an arrangement of the vibration means to the side of the substrate the desired vibratory motion may be particularly advantageous ^¬ adhesive applied to the stone.

It is advantageous if the vibration device is slightly inclined relative to the base or the vibration table, is arranged. The vibration device may have a conventional structure. It is particularly advantageous if the vibration device is a vibration pair or a vibrator pair or the vibration device has at least one pair of vibrators or vibrators.

It is advantageous if the vibrating means comprises at least one pair or a vibration Rüttlerpaar, which is designed such that a force acting in the passage Rich ^¬ processing component of movement of each vibrator of the vibrating pair mutually compensated.

Due to the design, it may happen that individual vibrators, for example due to the arrangement of the eccentric mass, also exert a force or a vibration input on the lower ^layer , which acts in the direction of passage. By a suitable arrangement of two vibrators or two vibrators which are adapted to one another, these Be ^¬ wegungskomponente can be compensated or eliminated, however, so that overall no BEWE ^¬ supply component acts acting in the direction of passage on the stones. This can be achieved particularly easily with two vibrators or vibrators whose eccentric masses are correspondingly offset.

It is advantageous if the vibration ^{device is} arranged horizontally next to or below the surface of the base, wherein the vibration ^device is inclined at an angle of 45 to 90 degrees, preferably 60 to 80 degrees, with respect to the plane of the base. This arrangement makes it particularly easy to achieve that the vibration device vibrates the base and thus the stones arranged thereon in the desired manner. Insofar as the vibration device is arranged in a plane which ^encloses an angle of 90 degrees to the plane which ^clamps the base (wherein in each case an axis of the "plane" of the vibration device or of the base runs in the direction of passage), it becomes particularly simple ensures that the vibration device only generates a vibration, which causes the stones to move substantially perpendicular to the stone surface of the stone to be aged. This corresponds to the above-described primary movement ^component . A secondary loading ^¬ wegungskomponente is not, at least not significantly in this case, respectively. However, inasmuch as the angle between the "plane" of the vibrator to the plane of the substrate, starting from 90 degrees, is reduced, for example to a value of 80 to 60 degrees or to a value between 85 and 45 degrees, is in a simple manner in addition to the primary component of movement the vorste ^¬ hend already described secondary movement component he testifies ^¬ .

All features shown in the description can be combined with each other, regardless of how the stones vibrate.

It is advantageous if the pad vibrates so that the stones are repelled at an angle of 1 to 45 degrees, preferably 10 to 30 degrees, from the surface of the pad and set in motion so that the stones move laterally towards and away from the stop surface.

In a structural embodiment of the invention can be provided that the pad has side walls which are formed as abutment surfaces. Thus, the surface of the stone to aging side on the side wall of the Un ^¬ terlage may strike. It is possible that one or both mutually parallel side walls of the lower ^¬ position are formed as stop surfaces. If both Be ^¬ tenwände are formed as stop faces two stones can be placed side by side in such a ^¬ the way that their side surfaces to aging are each aligned with a side wall of the pad on the pad.

It is advantageous if several rows of stones next to each other and substantially parallel to each other running on the pad are placed.

In an embodiment in which two such rows of stones are used, it can be provided that the side surfaces of the stones to be aged are respectively aligned with the adjacent side wall, which in this case can form the abutment surface. This effectively allows two rows of stones to age side by side.

In principle, it is conceivable in all embodiments to carry out the aging process either continuously or stepwise or intermittently. Continuously, in this case, be ^¬ suggest that the stones or rows of stones continuously through an aging area, by the stop surfaces is formed, be promoted. Alternatively, it is also possible to move the stones or rows of stones stepwise or intermittently through the aging area.

Various methods known from the general state of the art can be used for the continuous or stepwise conveyance of the stones through the aging area. Thus, for example, be provided that the pad has a conveyor belt or is provided with it, placed on the stones and through which the stones are conveyed through the aging area. However, it is also possible for the stones with the help ei ^¬ nes punch or other conveyor durchzufordern through the aging area or to push forward on the pad.

The backing can preferably be designed as a machining table forming ^¬. The pad may also be a vibrating table or any other pad for the stones.

It is advantageous if in all embodiments, the stop surfaces are selected such that for each aging side surface of an applied stone on the pad egg ^¬ ne stop surface is provided or the stop surfaces are chosen such that strike each aging side surface against a stop surface can. At this stop ^¬ surfaces may preferably be partitions or Be ^¬ tenwände the device. The partitions and Be ^¬ tenwände can be connected to the pad, but this is not mandatory. According to the invention, it can also be provided in a structural design that the side surfaces of two stone rows to be aged are aligned with one another and the aging side surfaces of the stones move towards and away from each other due to the vibration, so that the respective opposite side surfaces of two stones strike one another and form stop surfaces for each other. With this configuration, it is particularly easy to form the stop surfaces. Expensive constructive measures to form stop surfaces are therefore not necessary. In addition, no problems arise ^¬ wear.

In this embodiment, the solution of the invention can be reduced by particularly simple in that two rows of blocks are next to one another and parallel to one another on a base, so that the machining to ^¬ Tenden side surfaces opposed to each other. By the vibration device, the pad can then be set in motion such that due to the movement of the pad resting on the pad two stone rows move towards and away from each other, so that the side surfaces of the stone to be machined to each other, ie to the working side surfaces, suggest that the machined side surfaces of the stones mutually aging. All you have to do is make sure that the stones can not leave the surface due to the vibration. This is easily realized by appropriate side walls. In principle, more than two rows of stones can be aged in this way. This can be particularly useful if, as may be the case in special applications, two opposite side surfaces of the stone are to be aged. There are also known split blocks, which have two opposite side surfaces ge ^¬ gap faces. Thus, for example, with three rows of stones, the middle row of stones can strike between the two outer rows of stones, ie between their side surfaces to be aged.

Alternatively or additionally, it can also be provided in a structural embodiment that an intermediate wall is formed between each pair of stone rows, which forms or has the stop surface for the side surfaces to be aged of one or both rows of stones. It lends itself to when the partition wall for both rows of stones forms the contact surface and the aging side surfaces are therefore aligned respectively corresponding to the intermediate wall. Alternatively, or in addition thereto may also be ^pre-¬ see that the side walls are also formed as contact surfaces. Thus, it is possible, for example, that any number of rows of stones is conveyed by the device according to the invention, wherein the rows of stones are each ^¬ subdivision divided by partitions into channels and the outermost rows of stones are bounded by side walls, which may be formed as abutment surfaces. If appropriate, this solution can also be combined with the fact that individual intermediate walls are dispensed with and there, if necessary, the side surfaces to be machined abut against corresponding side surfaces of another row of stones to be machined. The abutment surface for the product to aging side surface of a stone may be designed as desired, and preferably abra- sive elements and / or peaks and / or Vorprünge and / or welding points and / or an irregular structure aufwei ^¬ sen. It is also conceivable to provide the abutment surface with exchangeable abrasive elements and / or tips and / or projections, so that the structure and the strength of the aging of the side surfaces of the stones can be changed by an exchange of these elements. Furthermore, can be achieved by replacing or retooling the stop surface adaptation to different stone heights and / or types of stones.

It may also be advantageous if the Anschlagflä ^¬ che, especially in an embodiment as an intermediate wall or as a side wall can be easily removed from the pad or generally from the device and replaced.

In a constructive development of the invention, additional stop members may be provided which are stationarily positioned and / or can be positioned in a controlled manner, so that, in particular, recesses and / or chamfers

and / or phases of the side surfaces of the stones to be worked on it due to the vibration movement.

In split bricks so-called splitting knives in Y-shape are known. As a result of this, the gap stone does not receive a uniform planar surface on the gap surface but has a chamfer or a recess or a phase at the edges, ie in the transition region to an adjacent side surface. For aging, this return jump additional fixed po ^¬ sitionierte or controlled positionable may be provided (for example, extendable and retractable) stop members. It is z. B. conceivable that such stones positioned at a designated position on the pad and on ^¬ closing a suitably suitable stop member is positioned on the recess or bevel, for example, in this from above or from below (from the pad) extended or fed becomes. By Vibra ^¬ tion movement then the return beats corresponding against the stop member, so that this area is aged. Furthermore, it is also conceivable that extend from the sides or intermediate walls corresponding stop members when the stone has reached a correspondingly suitable position. The stop members can also be stationary. In this case, for example, arise by a feed ^¬ movement of the stones, that the tapered surface or the recess / Phase of the side surface on the stationä ^¬ ren projection abuts. Optionally, this may also be designed in the manner of an obstacle parking, so that the additional stop member abuts the return, forcing the entire stone to a slight change in direction when it is transported further in the feed direction.

Basically, it is to be combined, of course, possible fixed stop members and extendable or controlled suppliable to ^¬ impact members or resilient or spring-loaded stop members to each other. The use of controlled in the aging path or the vibration path of the stones einbring ^¬ ble stop members may be particularly suitable to ange- sloping surfaces or recesses / phases of the stones to age, which are considered in the feed direction at the back of the stones.

It may be advantageous if, as an alternative or in addition to other stop members, additional stop members are provided, which are positioned by means of an elastic or flexible element such that bevels and / or recesses and / or phases and / or bulges or projections of the processed Side surfaces of it, due to the vibration of the substrate, strike and / or a channel 10, which is provided for conveying the stones, is narrowed by the stop members so that the stones are pressed against the stop members, the stop members due to the elastic or Dodge flexible element when the stone is further promoted in the direction of passage through the aging area.

The stop members may be designed, for example, in the manner of a scale or a shingle, which are preferably aligned ^¬ before such that their designed by a variety of scales or shingles surface is aligned against the passage direction, so that the stones on this particularly good or strong attacks. The stop member may preferably be attached to a side wall or egg ^¬ ner intermediate wall, for example vertically extending ^¬ be introduced. The elastic or flexible element can be any spring or a rubber or an elastomer, for example in block form. The elastic or flexible element may preferably be designed in such a way that, when the stone passes by, the stop element is pushed, must evade and this also due to the elastic ^¬ or flexible elements.

An advantage of this embodiment, it is compared to a rigid or controlled training of stop members that provided with the elastic or flexible element stop is not fixed, but flexible, but nevertheless a control is not necessary.

In one embodiment of the invention can be provided that the device has one or more such stop ^{Glienicke ¬} .

The stop members may be designed such that only the corners of the stones strike against them. Advantageous, it may be when the stop member protrudes so far into a feeding path of the stone that is so far narrowed to existing By ^¬ promotion channel, that the at ^¬ impact member and the side surface to be machined processed or at least unwanted projections or bulges the side surface to be edited.

The stop member can be combined with all other features of the device according to the invention and of the method according to the invention.

In one embodiment of the invention can be provided that the abutment surfaces vibrate. In one possible embodiment, the vibration of the abutment surfaces can take place in that the abutment surfaces (eg side or intermediate walls) are firmly connected to the substrate. It However, it is also conceivable to decouple the abutment surfaces of the pad and to let them perform an independent vibration ^¬ movement, for example, in and against the feed direction of the stones or up and down or a mixture thereof. The stop surfaces can also perform a movement in the direction of the stones and away from them. Such embodiments may be advantageous for modifying or influencing the aging ^pattern .

In a further constructive embodiment it can be provided that below the pad a substantially pa ^¬ rallel to the longitudinal axis of the stop surface or parallel to the feed direction of the stones extending axis of rotation is ange ^¬ arranged, which rotatably supports the pad. The Unterla ^¬ ge can thus rotate during vibration with a kreisbo ^¬ genförmigen movement around the axis of rotation back and forth. The movement can be effected preferably within a small win ^¬ kelber eich (z. B. <45 °, preferably <20 °). Such a mounting of the base ensures that the stones move a little more irregularly, whereby the aging pattern of the side surfaces to be aged can be improved.

In order to generate the vibration movement acting perpendicular to the stone surface to be aged, a multitude of possibilities are suggested from the general state of the art. For example, this corresponding eccentric or ^¬ same can be used, which preferably shaking pad or scroll horizontally. In the embodiment in the below the pad one parallel to the feed direction is provided extending axis of rotation, which supports the pad, can also be provided that the Vibrationsbewe ^¬ tion is initiated directly over the axis of rotation.

In the method according to the invention for the artificial aging of bricks, in particular of concrete blocks, brick clinkers and natural stones, it is provided that the bricks pass through an aging area which has a base on which the bricks are applied with an underside such that an upper side of the brick faces upwards is aligned ^¬ tet. A forward surface of the stone in the direction of passage thereby forms a front side and a surface of the stone which lies behind in the direction of passage ^¬ a back side. At least one of - based on the passage direction and the top surface of the stone - laterally aligned side faces of the stone is aligned with egg ^¬ ner stop surface substantially coplanar. In the inventive method it is provided that the stones are set by a movement of the pad in such a way in motion, that the stones to move toward the stop ^¬ surface to and away from the side, and wherein the movement of the underlay is selected in such a that the thus proposes at least one page to be processed surface on the stop face on ^¬ that the stop face acts aging on the side surface.

The movement of the pad is preferably carried out vibrating or oscillating at high frequency.

The pad is preferably moved in a horizontal plane. The pad will preferably be substantially transverse or moved perpendicular to the feed direction of the stones or to the longitudinal axis of the pad.

The advantages of the method according to the invention will become apparent from the comments on the advantages of the device according to the invention analog. It is advantageous in the erfindungsge ^¬ MAESSEN method when two stones are placed on the pad so that their aging stone surfaces are aufei ^¬ aligned and move the aging side surfaces of the stones toward each other and away from each other by the movement of the pad and strike each other in such a way that the aligned side surfaces are aged and the stones each form a stop surface for each other.

An advantage of the inventive method it is when at least a first and a second row of stones ne ^¬ by side are placed on the pad, so that the aligned aging side faces of the first row of stones to be aged side surfaces of the second row of stones are and move through the vibration to age ^¬ the side surfaces of the stones toward each other and away from each other, the stone rows each form stop surfaces for each other.

In the inventive method may further be provided that a side wall of the base, which limits the movement of the stones seitli ^¬ che, ^¬ be formed as a stop surface, against which the side surfaces of the stones hit under aging action. This solution also makes it possible to operate the method particularly effectively, since the Function of the side wall and the function of the stop surface can be realized in one part.

It is advantageous when the movement of the support essentially moves the sti ^¬ ne perpendicular and perpendicular to the stone surface to aging. This can be particularly effective to use the vibrato ^¬ onsenergie. ^Of course, it is not excluded that the stone also has a different component of movement during the vibration. This can be the case in particular if the method according to the invention (or the device according to the invention) is designed as a continuous system in which the stones are conveyed continuously through the aging region. In this case, in addition to the movement component caused by the vibrating device or the vibrating aggregate, the stone has a component of movement in the advancing direction of the stones, which preferably acts at 90 ° to the movement component of the vibrating device. Both movement components act essentially in a horizontal plane, ie in a plane which runs parallel to the support surface of the pad for the stones.

In the method according to the invention, the use of additional stop members can also be provided in a structural design, which can be introduced into the aging area and against which the side surfaces to be aged strike. The additional stop members can thereby be designed in such a way as has already been where he ^¬ inventive device described. An advantage of the method according to the invention is when the stone is a split stone and the side surface to be aged is the gap surface of the stone.

In principle, all features that have been described for the device according to the invention can also be used in the method according to the invention. Conversely, all features which have been described with regard to the method according to the invention can also be used in the device according to the invention.

It is advantageous, when inserted in the orientation / position, in which they were produced in a slitting line within an overall production process, the produced ^¬ stones, in particular concrete stones. In the cleavage plant, the stones are then split into two or more parts, so that after splitting the concrete block, the cleavage surfaces of the resulting cleavage stones are opposite each other or aligned with each other. Subsequently, the split stones are introduced while maintaining their position / orientation in the device according to the invention or it is the he ^¬ inventive method performed so that the Spaltflä ^¬ Chen the split stones are aged. After passing through the aging process, the stones can be together mensortiert ^¬ back layer by layer, without tilting of the stones is necessary.

Advantageous further developments and embodiments of the invention will become apparent from the further dependent claims.

The stones used in the embodiment are so-called Spaltstei ^¬ ne, which are preferably formed of concrete. The dung OF INVENTION ^¬ contemporary device is not limited thereto, but rather all of the features described below can regardless of whether they have a cleaved surface or not, also be used in any other stones, especially when natural sto ^¬ NEN clinker and brick.

As can be seen from the figures, the device according to the invention has a base 1. On the pad 1 stones 2 can be applied with a bottom 2a such that a top 2b of the stone 2 is oriented upward. In the exemplary embodiment, a front surface of the stone 2 lying in the direction of passage represents the front side 2c and a rear surface of the stone 2 a rear side 2d. The passage direction of the bricks 2 through the device or aging region 3 in the exemplary embodiment is represented by the right ^¬ tion arrows A shown.

In the exemplary embodiment it is provided that the upper ^¬ side 2b of the block 2 is at the top when the stone is installed or relocated later. The later visible surface ver ^¬ runs preferably 90 ° offset from the top 2b.

Based on the passage direction (arrow A) and the Obersei ^¬ te 2b have the stones 2 laterally aligned Seitenflä- Chen 2e, which are aligned substantially plane-parallel to a stop surface 4.

In the exemplary embodiment, both examples are shown in which only one side surface 2e of the stone 2 is aged (see, for example, Figure 2, Figure 5, Figure 6, Figure 8 and Figure 9), as well as an example in which both side surfaces 2e of the stone 2 are aged (see Figure 3).

All features that are described in the embodiment with respect to ei ^¬ ner of the two embodiments can also be used in the other embodiment.

After the bricks 2 are formed in the exemplary embodiment as split bricks, the side surface 2e to be aged is the slit surface of the split slab 2. In the exemplary embodiment, this is the later visible surface. Insofar as a gap stone 2 should have two gap surfaces 2e, it can be provided that corresponding stop surfaces 4 are formed, so that both gap surfaces 2e can be aged.

In the exemplary embodiment, the movement of the base 1 is generated by using a vibrating motor or a vibration ^¬ device 5. In Figures 1, 2, 3, 8, 9, 10, 11, 12 and 13, the movement of the pad 1 is symbolized only by the double arrow B. FIG. 5 shows a possible embodiment of the vibration device 5, in which the use of an eccentric is provided. A similar representation is also provided according to FIG. Alternatively, a vibrating motor can be used or a ne other suitable device by which it is possible to set the pad 1 in such a way that - due to the movement of the pad 1 - the lying on the Un ^¬ terlage 1 2 stones in the direction of the stop surface 4 to and from move this away, so that the gap surfaces 2e of the stones 2 so abut against the Anschlagflä ^¬ chen 4 that the abutment surfaces 4 act on the gap surfaces 2e of the stones 2 aging.

The substrate 1 is moved so that the rest ^¬ the split blocks 2 move substantially perpendicular to the at al ^¬ ternden gap surface 2e of the stone. 2 In the exemplary embodiment it is in the direction of movement as ^¬ at about a movement transverse to the direction (direction of arrow A). Both the passage direction and the movement that can be generated by the vibration device 5 lie in a horizontal plane (preferably at right angles to one another). Heretofore, the embodiment shown in Figure 6 differs slightly, since there the vibrator 5 or a similar device generating a movement due to the rotation axis 6 and the rotary shaft, via which the base 1 is rotatably mounted a circular-arc Be ^¬ movement of the support 1 and thus the overlying stones 2 generated. Although the pad 1 and the stones thus move substantially transversely to the direction of passage of the stones, but thereby perform a slight circular arc-shaped movement or a radial movement (see double arrow B of Figure 6). The embodiment shown in Figure 6 may have the advantage that the generated thereby on the stones 2 BEWE ^¬ supply is somewhat chaotic and random characterized as a purely horizontal movement. Due to the slight arc track or the radial component of the stone 2 can easily tilt, causing the stone 2 abuts more irregularly on the associated plant surface 4.

The base 1 is in such a way be ^¬ moved in the embodiments that the resting on the support 1 gap ^¬ stones 2 in a substantially horizontal plane transversely to the direction reciprocate and thereby to abut against the stop surfaces. 4 In the embodiment according to FIG. 5, the "horizontal plane" is inclined by an angle of +/- 10 °. This should generally fall within the scope of the invention under the term horizontal plane, regardless of how the deviation is generated.

The pad 1 moves in the embodiment for this purpose within a horizontal plane back and forth, ^{vorzugswei ¬} se transverse or perpendicular to the feed direction of the stones. 2

Figures 1, 2, 3, 6, 8 and 9 show embodiments of the device according to the invention, in which the side walls 7, which are parallel to the feed direction of the stones 2 (passage ^¬ direction according to arrow A), simultaneously form the An ^¬ impact surface 4. The side walls 7 and the abutment surface 4 shown in Fi gur ^¬ 1 is provided with abrasive elements ^¬ Ele. 8 This results in a particularly good aging effect or a better aging effect than if it is a flat surface. Figure 4 shows - for all embodiments - possible variants of abrasive elements 8, with which the stop surface 4 can be provided. In question come here abrasive elements 8 in one any configuration and / or tips and / or projections and / or welds and / or an irregular Struk ^¬ ture. It can also be provided that the stop surface 4 is provided with interchangeable elements 8, which protrude accordingly in the direction of the gap surface 2e from the plane of the stop surface 4. This has the advantage that in the event of wear not the entire stop surface 4, but only the corresponding abrasive elements 8 must be replaced. Moreover, can be easily dealt with different ^¬ Liche block heights, different rock materials, or by the user to the desired aging image by replacing the corresponding abrasive elements. 8

Figure 1 shows to illustrate the device according to the invention only a common large channel through which the stones to be aged 2 can be performed.

FIG. 2 shows a variant of FIG. 1, in which it is provided that different channels 10 are formed by intermediate ^walls 9, each of which is suitable for carrying out a row of stones. The intermediate walls 9 can serve on one or both sides as stop surfaces 4 or be designed accordingly. In Figure 2, different variants are shown, which can be combined with each other. It is provided that both side walls 7 are formed as stop surfaces 4, while only one of the intermediate walls 9 is formed on one side as a stop surface 4. FIG. 3 shows a further variant of the device according to the invention. In this case, analogous to FIG. 2, two intermediate walls 9 are again provided, which, however, in this embodiment are designed as stop surfaces 4 on both sides. Further, the side walls 7 are constructed as stop faces on ^¬. 4 In Figure 3, ei ^¬ ne series of gap stones 2 (each having two cleavage planes 2e to aging) is exemplified which are ge ^¬ pushed by a pin 10.

Figure 5 differs from the embodiments according to Figures 1 to 3 characterized in that the side walls 7 are not formed as a stop ^¬ surfaces 4. The stop surfaces 4 are formed in the example illustrated in Figure 5 embodiment in that in each case two bricks 2 and two Steinrei ^¬ hen 2e are opposed with their joint surfaces, so that - due to the transverse movement, which is generated by the vibration ^¬ device 5 - The gap surfaces 2e of two opposing stones 2 or rows of stones abut each other. In this case, the stop surfaces 4 are thus formed by the respective opposite gap surfaces 2e of the stones 2 themselves.

The side walls 7 may optionally be provided in Figure 5 with a rubber lining or other elastic coating. This is also possible in other embodiments of the device according to the invention, when the side wall has no stop surface 4 in the sense of the invention or is provided with abrasive elements 8 accordingly. FIG. 6 again has an exemplary mixture with regard to the design of the stop surfaces. It is provided that a side wall 7 is formed as a stop surface 4 ^¬ , also have all three partitions 9 on ei ^¬ ner side, each aligned with a split surface 2e ei ^¬ nes stone 2 or a row of stones, a corresponding off ^¬ education as a stop surface 4 on.

In principle, all design variants of the stop surfaces 4 can be combined with each other as desired. Furthermore, the drive concept, as it is shown for example in Figures 5 and 6, be mounted in all the illustrated embodiments.

Figure 7 shows two split blocks 2 with a special ^¬ From coinage. Such split stones are as Y-split bricks be ^¬ draws. The split stones 2 shown in FIG. 7 have been created by splitting a stone into two parts by means of a so-called Y splitting knife. It is on the basis of the ^¬ Y-shape of the splitting blade has a bevel 11 is ^¬ forms, their aging makes special demands. In Figures 8 and 9 show two variants are in principle Darge ^¬ provides with which the bevels / phase / recesses 11 of the split blocks 2, as this provides Darge ^¬ in the figure 7, may be particularly advantageous aged.

For this purpose, FIG. 8 provides a kind of obstacle course, ie the side walls 7 of the underlay 1 shown in FIG. 8 have additional stop members 12 which are formed in the embodiment shown in FIG. 8 by bulges of the side walls 7, ie the side walls 7 Do not run completely parallel to the direction of flow (arrow A), but are bent so that the chamfers 11 can strike the kinks.

Basically, the embodiment illustrated in Figure 8 execution ^¬ form can also be designed with partitions which have a similar pattern, so that corresponding channels 10 are formed.

FIG. 9 shows an alternative to FIG. 8, which can also be used as a supplement. It is provided that the split bricks 2 are applied to the substrate 1 up to a defined position (in FIG. 8, three rows of two bricks 2 are shown, but the solution is not limited thereto). After reaching the intended position stop members 12 are extended from above, from below or from the side walls or partitions or positioned so that they rest against the chamfers 11 and adjoin it. As can be seen from FIG. 9, it can be achieved with a stop member 12 that it processes four chamfers 11 of four different stones 2. Preferably, the split stones 2 are thereby aged in the illustrated position until both the non-tapered sections of the split surface 2e and the bevel 11 of the split surface 2e in the desired manner by the transverse movement or the movement of the stones 2 in the direction of the stop surfaces 4 and the stop members 12 are aged in the desired manner. On closing ^¬ the stop members 12 can be removed again, retracted or otherwise removed, so that the split stones 2 in the direction of passage (arrow A) on- can be transported. The next layer of stones 2 can then be fed.

In one possible embodiment, the stones can also be placed on the base by a gripping tool. In this case, the stop members shown in Figure 9 may also be formed stationary.

Of course, the variants shown in Figure 8 and Figure 9 can be realized with the stop members 12 in all embodiments and are not limited to the illustrated embodiment.

The inventive device can be realized both with a continuous forward movement, continuously sideways shaken at or shaken or vibrated or spun (particularly Figure 6), and in a variant in which the stones 2 in a designated Po ^¬ sition inserted and held at this point, until by the Rüttelprozesses a desired aging he ^{¬ is} enough. In the embodiments, for each side surface 2 of each stone 2 a stop surface 4 vorgese ^¬ hen.

The stone surface is aged in the embodiments is, when the stone 2 installed or later transferred to 90 ° to the upper surface 2b of the stone offset ^¬ be directed.

In the following, further variants of the solution according to the invention will be described with reference to FIGS. 10 to 13. The following The features of the exemplary embodiments shown in FIGS. 10 to 13 can be combined with all the aforementioned exemplary embodiments, in particular also with the features of the general description. It does not matter in particular how the pad 1 itself is designed specifically, that is, whether the side walls 7 or the Zwi ^¬ rule walls 9 (insofar exist) on one or both sides have stop surfaces 4 and / or if more stop members 12 are present are. Furthermore, the manner of designing the vibration device 5 is not important.

Figure 10 shows an embodiment of the device according to the invention with a pad 1, which is designed according to Figure 6. However, the detailed design of the base 1 does not ^matter . In the following, FIG. 10 will be described only with regard to the relevant deviation, otherwise reference is hereby made to the already described embodiments. An embodiment of the vibration device 5 is provided with a vibration pair 50 which, as can be seen in FIG. 11, is composed of a first vibrator 50a and a second vibrator 50b. FIGS. 10 and 11 differ only in terms of the design of the side walls 7 and the intermediate walls 9. The principle of the arrangement of the vibration device 50 is identical in FIGS. 10 and 11.

As is apparent from Figures 10 and 11, the Vibrati ^¬ onspaar 50 is arranged slightly obliquely. The Vibrationseinrich ^¬ device 50 runs parallel to a direction of passage A of the stones 2 and is located laterally on the substrate. 1 The vibration device 50 is at the level of the pad or possibly also slightly below the pad 1 angeord ^¬ net. The vibration device 50 is inclined at an angle of approximately 60 to 80 degrees relative to the plane of the surface, as ^¬ out shows that the vibration device 50 generates a primary and a secondary component of motion. The pri ^¬ mare motion component causes the stone moves perpendicular to the side surface 2e to aging of the stone 2, and thereby abuts against the stop members. 4 The second ^{component of} movement, which generates the Vibrationseinrich ^¬ device 50, causes the stone from the pad 1 is slightly raised or moves on this irregularly up and down. Due to the inclination of the vibration device by an angle of 60 to 80 degrees, wherein also an angle of 50 to 85 degrees or an angle of 45 to 90 degrees can be provided, it is achieved that the majority of the vibration ^¬ onsenergie in the primary component of motion is implemented while a relatively small part of the vibration energy is converted into the secondary component of motion and thus leads to a hopping or an up and down movement of the stone on the base 1. The resulting from the arrangement of the vibration device 50 total movement component, which is composed of the primary and the secondary component of motion, is shown in Figure 10 with the Dop ^¬ pelpfeil B.

Figures 10 and 11 show an embodiment of the vibration device 5 with only one pair of vibration 50. In principle, a plurality of pairs of vibration 50 may be provided. Furthermore, the embodiment illustrated in FIGS. 10 and 11 is not based on the pairwise arrangement of vibrato ren 50a, 50b limited, there may be other numbers of vibrators provided. However, the configuration shown in FIGS. 10 and 11 with a vibration pair 50 which has a first vibrator 50a and a second vibrator 50b has proven to be particularly suitable. The eccentric weights 52a, 52b of the vibrators 50a, 50b may advantageously be aligned to each other and coordinated so that no or no wesentli ^¬ surface acting in the direction of passage of the stones 2 Vibrationsbe ^¬ movement is exerted on the stones. 2

12 shows a specific embodiment of an on ^¬ impact member 13. The stop member 13 is elastically supported by an elastic or flexible member 14 and spring-biased so that the stop member can yield 13, if the stone is in the direction of passage A through the aging region 3 further is encouraged. In the exemplary embodiment, the elastic element is a compression spring. The stop member 13 is attached to a side wall 7, but this may also be an intermediate wall 9 or other suitable element.

As can be seen particularly clearly from Figure 12, the stop member 13 can, due to the compression spring 14 as in the pre ^¬ push distance of the stone 2 place that bevels and / or recesses phases to be processed and / or and / or bulges or protrusions of the Side surfaces 2e thereto, due to the vibration movement of the pad, anschla ^¬ gene. In the embodiment of Figure 12 is beyond (not necessarily) provided that the stop member 13, the channel 10, which is provided for conveying the stones, so narrowed that the stones 2 are already thereby pressed against the abutment ^¬ member 13. Thus insbeson ^¬ wider bulges or protrusions on the side surface to be processed can edit 2e particularly well.

In Figure 12, also a ^full-¬ staltung is optional and dashed lines shown, which can be selected when a stone is to be processed, which, as shown in Figure 3, has on both sides of a page to be processed surface 2e. The corresponding parts bear the same reference numeral and are provided with an apostrophe.

The embodiment illustrated in Figure 12 can be combined with any type of vibration, as it was shown in the present invention, and be combined with any ^¬ arbitrary design of the pad. 1 The same also applies to the subsequently driven exempla ^¬ illustrated with reference to Figure 13 of a further embodiment Anschlagele ^¬ ments 15 °.

The embodiment shown in Figure 13 from Figure 12 in that can be processed in a particularly suitable manner both in the travel direction (direction of arrow A) at the front lying phase or chamfer of the stone 2 and ei ^¬ ne lying behind phase or chamfer at failed ^¬ det. For this purpose, two stop members 15 are provided, between which an elastic or flexible element is arranged ^¬ 16, which defines the stop members 15 together menzieht ^¬. Instead of an elastic or flexible element 16, a suitable other device may be provided. In the exemplary embodiment, it is optionally provided that at least one of the two stop members 15 is guided via a linear guide 17, so that the two stop members 15 can perform an advantageous movement to pass a stone 2. When passing the stop members 15, the stone strikes against the facing abutment surfaces of the stop members 15 and thereby pushes the two stop members 15 apart or in the direction of the side wall 7, where the stop members 15 are optionally be ^¬ steers. Through the feed motion of the stone 2, the elastic or flexible element 16, which preferably is a tension spring in the off ^¬ operation example will ge ^¬ stretched, so far, until the stone could happen. 2 Subsequently ^¬ ßend draws the tension spring 16 the stop members 15 again defined as the fact that these are preferably positioned in the manner of a roof and forms an advantageous contact surface.

Now, if the stone 2 (as shown in Figure 13) at an angle of 90 degrees (double arrow B) is vibrated to the feed direction A, both the front chamfer and the rear chamfer of the stone 2 can strike. In the exemplary embodiment, the front chamfer of the stone 2 to the stop member 13 and the rear suggests to the facing ^¬ stop member 15 at.

In one embodiment of the invention can also be provided that the stop member 13 by two stop members 15, which are braced together by a tension spring 16, he ^¬ sets. Alternatively or in addition to the stop members 15 may also be provided a fixed or controlled stop. If it should be a fixed stop, it can be provided that the stone 2 is skewed by the conveying movement in the direction of passage A and the resulting impact on a stop member 13 within the channel 10, so that its rear end to a fixed stop 12 strikes.
