Definitions

  • the invention relates to a device for the artificial aging of stones, in particular of concrete blocks, brick clinkers and natural stones according to the preamble of claim 1.
  • the present invention also relates to a method for the artificial aging of stones according to the preamble of claim 34.
  • a generic device for aging is from the DE 20 2004 020 206.9 known.
  • Stones such as covering elements, facade elements, sand-lime bricks, concrete blocks, brick or brick clinker, natural stones and the like, are often subjected to a post-treatment, regardless of their material properties, thereby losing their artificial appearance.
  • sorting systems are known for sorting the stones, which align the stones accordingly and arrange them in a pallet.
  • Such sorting systems cause high acquisition and operating costs and also have a corresponding space requirement.
  • the stones are arranged in one or two layers, preferably in their production position, between two elements, preferably plates.
  • the lower plate, on which the concrete blocks rest, is in operative connection with a vibration device.
  • the vibration device causes the stones to move so that they move back and forth between the plates.
  • the stones hit each other as well as on the upper and the lower plate, whereby the edges are broken at the top and bottom.
  • the top and bottom of the stones are struck by the respective associated plates.
  • the vertical side edges of the concrete blocks and the side surfaces are broken or struck by the adjoining concrete blocks.
  • edge break is the worse, the larger the aging stone. This results from the fact that the stop angle becomes flatter the larger the stone placed between the plates. The flat stop angle results in an unfavorable breakage of the edges.
  • the DE 20 2004 020 206.9 a device for the artificial aging of stones is known, in which the stones - preferably in their production position - are placed on a base, so that the surfaces to be machined and the adjacent edges of the stones are exposed. Subsequently, by means of a magnet freely movable striking bodies (made of metal) are applied to the surface to be machined. By means of a vibration device, the base on which the stones rest, vibrated. Thus, the stones and the impactors are brought to each other in such a way that the impactors act on the surfaces and the exposed edges of the stones.
  • the metallic impactors are again lifted off the surface of the stones by the magnet - as it approaches the stones.
  • the stone layer can be removed and a new stone layer fed.
  • the disadvantage is that the magnet to be used causes high costs.
  • Another disadvantage is that by storing and resuming the impactor by the magnet corresponding non-productive times arise that lead to longer cycle times.
  • DE-A1-100 39 463 discloses an apparatus and method for stone artificial aging according to the preamble of claims 1 and 34, respectively.
  • the present invention is therefore based on the object to improve the known from the generic document device for the artificial aging of stones, in particular to develop a device and a method which allows a particularly cost-effective and rapid aging of stones.
  • the solution according to the invention allows several variants of the storage or the removal of the impactor from the surfaces of the stones and thus several ways to dispense with a previously necessary magnet.
  • the mounting device, on which the impactors are movably mounted can perform a lifting movement, so as to be able to lift the impactor from the surface of the stones or to supply this.
  • the lifting of the impactors of an aged layer of stones and the reassignment of the impactors to a new aging stone can be done quickly in this way, so that short cycle times can be met.
  • the non-productive times are significantly reduced compared to the prior art.
  • a particular advantage of the solution according to the invention is that it can completely dispense with lifting and reassembly of the impactor.
  • the movable attachment or suspension of the impactors namely, the device according to the invention with a conveyor, for example in the form of a push rod or a conveyor train, which effetschiebt the aging stones continuously or continuously or discontinuously below the movably mounted impactors. Under a continuous aging is also an interval to understand in which the stones with short interruptions of z. B. 5 seconds are pushed below the impactor.
  • the impactors - stimulated in the usual way by the vibrations introduced - thereby act aging on the stones.
  • the defined range can be selected, for example, as a function of the number of impactors, the number of stones and the passage speed.
  • the impactors are arranged on a holding device arranged transversely to the feed direction both in the feed direction and transversely to uneven or irregular, so that regularities in the aging of the stones are avoided.
  • the impactors are arranged in several rows transversely to the feed direction of the stones such that the rows of impactors each span the stones conveyed through.
  • the aging effect can be varied by the number of rows of impactors, below which the stones must pass under beating action of the impactor.
  • the strength of the aging is determined by the throughput speed, as well as the vibrations introduced.
  • the device according to the invention can be easily integrated into the ongoing production process of stones, without this leading to a cycle time reduction.
  • the stones can pass through the generic device at the desired speed, wherein the desired aging effect is achieved by the number of rows of striking bodies.
  • the impactors of a row can each be arranged offset to a front or lower row of impactors, so that the surfaces of the stones can be processed uniformly.
  • a system-related (permanent) accumulation of attacks of stones within a certain range is reliably avoided by the staggered arrangement. It can also be provided in this regard that the distance between the rows is different.
  • the impactors are mounted such that the defined areas of the individual impactors together at least the entire surface - preferably the layers supplied in layers.
  • the stones are fed to the area in which they are aged in one piece and aged in one operation, i.
  • the stones are not transported until the aging is over.
  • discontinuous aging it is also possible to provide a plurality of aging stations, to which the stones are fed in succession, the stones, after they have passed through all the aging stations, being aged in the desired manner.
  • the stones are permanently transported in the feed direction, so not a location or unit of stones targeted the or the aging stations is fed, but it is a continuous process. This is also possible by an interval feeding the stones.
  • the vibration process does not have to be interrupted for this purpose.
  • the stones are thereby for a relatively short period of time, e.g. 5 seconds, left in its position (no feed) and then transported a bit further. In experiments, this has resulted in an advantageous aging image without a systemic accumulation.
  • the defined regions of the impact bodies overlap.
  • the predetermined by the movable mounting movement space, which have the impactor should preferably be chosen such that the impactor can not penetrate into the possibly between two stones forming gap. According to the invention it is provided that the impactor rest in the resting state, that is, when no vibrations act on the stones and the impactors rest on the stones.
  • the impactors are arranged at a distance above the stones.
  • the stones can thus be transported without scratching underneath the impactors.
  • a distance between the stones and the impactors is easily possible, especially in thicker stones, since they can be aged with a high amplitude and thus be pushed up accordingly.
  • a distance increases the aging of the stone edges and reduces the aging of the stone surface, which may be advantageous depending on the application or desired appearance.
  • the defined area within which the striking bodies can move on the surface of the stones corresponds to a movement or deflection thereof of 5 to 40 mm, preferably 10 mm, in all directions. Assuming that the impactors are spherical and have a diameter of 40 mm, this would give a circular defined area with a diameter of preferably 60 mm. The circumference or horizontal cross section of the impactors is stretched horizontally in all directions by 10 mm to image the defined area.
  • the holding device to which the striking bodies are fastened, is arranged above the stones.
  • the mounting device can represent a plane extending parallel to the surface of the stones or a pattern of holding elements, for example formed by a plurality of holder rows running transversely to the direction of passage of the stones.
  • the attachment of the impactor to the support members can be done via fasteners, which may be formed, for example, chains, ropes, rods or profile elements of different design.
  • the fastening members can be configured in many ways, preferably to ensure that the impactors can move as unrestricted as possible within the defined range, on the other hand, the impactor can perform the lifting movement without much loss of energy.
  • the impactors are each individually secured to the support members.
  • the means may for example be formed as elevations over which the underside of the stones are pushed due to the feed movement (resulting from the conveyor).
  • the elevations may preferably be formed in a ramp shape, so that the stone moves up the ramp at least with a partial area and then falls down again or moves it down again.
  • the elevations are arranged such that the stones are pushed with its underside off-center on the elevations, whereby each side of the stone (viewed in the direction of passage) is subjected to increased aging. It is envisaged that each stone on each side is raised at least once.
  • the elevations have rollers or are formed as rollers. The fact that the stones are raised anyway anyway by the vibration movement in this area, the friction between the increase and the underside of the stone is not high anyway.
  • the means for lifting the stones may also be formed as in the US 2002/0145224 A1 is described.
  • Advantageous embodiments and further developments emerge from the further subclaims. Below, two embodiments of the invention are shown in principle with reference to the drawing.
  • any stones for example covering elements, facade elements, sand-lime bricks, concrete blocks, bricks or brick clinker or natural stones are aged regardless of their material properties.

  • the vibration device 6, which may for example consist of several unbalance generators, transmits the vibratory motion to the pad 2 and acts from there on the stones 1 and the impactor 3.
  • the pad 2 can also represent the top of the vibration device 6, for example, a vibration table. However, the pad 2 may also represent a conveyor belt on which the stones 1 are placed. With regard to advantageous embodiments for this purpose and the initiation of the vibratory motion is on the DE 20 2004 020 206.9 directed.

  • FIGS. 5, 6 and 7 is one to the FIGS. 2 to 4 alternative embodiment of the fastening members 8 shown.
  • the fastening members 8 in this case have a profile through which an inner space 8a is formed, which is suitable, the (in Embodiment tubular or rod-shaped) support member 7 to be included so that the fastening member 8 is movable relative to the support member 7 such that arranged on the attachment member 8 or associated impactor 3 both a lifting movement and a movement within the defined area. 4 can perform.

This is due to the fact that in a conveyor 10, as this in Fig. 8 and Fig. 9 is shown, the thrust, the push rod 11 exerts on the stones 1, is getting larger the closer the stones 1 are arranged on the push rod 11. It may happen that the stones 1 are pushed together in such a way that the stones 1 in particular in the region of the push rod 11 less or no longer bounce. This effect is all the more visible, the smaller the stones are, because the rows of stones, on which a lower thrust pressure is exerted, so the rows of stones that are forward in the conveying direction, hop significantly higher or vibrate much stronger and thus struck their stone edges stronger become.

  • the support 18, in particular when it is formed of an elastic material the risk of breakage is reduced considerably, since the stones 1 no longer impinge on the base 2, which is usually formed of steel, but on an elastic material, preferably rubber.
  • Fig. 12 is a variation of the in 10 and FIG. 11 illustrated embodiment of the conveyor 10, which has substantially the same advantages.
  • the embodiment according to Fig. 12 also has a chain conveyor 10 and a push rod 11 and optionally a limiting rod 17, which analogous to the embodiments according to Fig. 8 and Fig. 9 respectively.
  • 10 and FIG. 11 are arranged.
  • the support 18 is designed as a circulating conveyor belt, which is preferably formed substantially of an elastic material, such as rubber.
  • the conveyor belt 18 extends in such a way that it is vibrated by the vibration device 6, whereby the resting stones 1 hop or vibrate.
  • the conveyor 10 is preferably arranged such that neither the chain strands nor the push rod 11 or the limiting rod 17 vibrate.
  • the conveyor belt 18 is connected to one or more limiting rods 17 or push rods 11.
  • the stones 1 due to their vibration (at low speed) move backwards relative to the conveyor belt 18. This rearward movement is limited by the push rod 11 accordingly.
  • the thrust pressure which the push rod 11 exerts on the stones 1 is so small that it does not disturb the vibration or the hopping movement of the stones 1.
  • the limiting rod 17 prevents the stones 1 can leave the intended area forward.
  • a chain conveyor 10 may in the embodiments according to the FIGS. 8 to 12
  • another conveyor which is preferably configured circumferentially, can be used.
  • Fig. 13 shows an embodiment of the push rod 11 and the limiting rod 17, which is particularly suitable for the aging of trapezoidal in cross-section or generally unstable in their position stones 1.
  • Such stones 1 may be, for example, split or split stones, which generally have an uneven or raised and recessed surface.
  • the inventor has found that regardless of the embodiment of the conveyor (in Fig. 13 not shown) and regardless of how the stones are transported through the aging area ( FIGS. 8 to 12 ) the aging result of stones 1, which rest unstable on the pad 2 can be improved by the push rod 11 and the limiting rod 17 are formed such that they support the stones 1.
  • both the push rod 11 and the limiting rod 17 an additional support member 11a and 17a.
  • a plurality of support elements may be provided or the push rod 11 and the limiting rod 17 as such have a shape which is suitable to support the stones 1 and to avoid their tilting.
  • the support elements 11a, 17a it is achieved that the surfaces 1a of the stones 1 form a horizontal plane as possible, so that the stone surfaces 1a can be advantageously aged by the impact body 3.
