Definitions

  • the present invention concerns a method and device for distressing, in particular visually ageing stones.
  • This known technique is disadvantageous in that the stones leave the drum in a disordered manner.
  • the further transport of the stones can take place either in an disordered manner, for example in container bags, or an ordered manner, for example stacked on pallets.
  • container bags are disadvantageous in that they are expensive and difficult to handle.
  • the invention aims a method and a device for distressing stones based on an entirely different concept than the distressing by means of a drum, and which offer the advantage that among others the above-mentioned disadvantages can be excluded.
  • the invention aims a method which can be realized with a relatively small device, as opposed to the relatively large drums which have been used until now for distressing stones.
  • Another aim of the invention consists in offering a method for distressing stones which makes it possible to distress concrete stones relatively soon after their production.
  • the concrete stones must have hardened very well, which implies that these concrete stones must harden first for 7 to 14 days, which requires a large storing space for the intermediate storing in case of large productions.
  • the invention concerns a method for distressing stones, in particular the visual distressing of stones, whereby the stones are provided between two or several elements in between which they are beaten.
  • the method is carried out such that the stones are entirely prevented from turning on their sides or from rotating between the two above-mentioned elements, such that the position of the stones cannot change during the manipulation and such that stones which are supplied in an orderly manner also leave the device in an orderly manner.
  • the stones are preferably provided such between the two elements that their smallest dimension extends according to the direction perpendicular to the above-mentioned elements.
  • the stones are beaten back and forth between the two elements by subjecting one or both of these elements to a vibratory movement.
  • the elements are kept at a mutual distance from one another during their movement, in particular during the vibratory movement, which is always smaller than twice the thickness of the stones provided in between.
  • the stones in case several stones are manipulated simultaneously, cannot shift and/or roll over one another, so that they remain ordered in at least one plane.
  • the stones are handled in groups, whereby the simultaneously handled stones are situated next to one another in one layer, for example in an amount which coincides with a pallet layer.
  • These stones are hereby preferably also guided and/or supported sideways, so that they do not only remain arranged in one plane, but also remain lying next to one another in an orderly manner during the distressing process. A separate sorting handling at the end of the distressing process is thus excluded.
  • elements are used of which one or both of the sides directed to one another are provided with profilings, such as thickenings, to promote that pieces are beaten off the stones, whereby the stones are preferably placed such opposite these profilings that said profilings are situated on one or several of the angles of the stones.
  • profilings such as thickenings
  • the device according to the invention consists of two elements in between which the stones are beaten back and forth.
  • these elements consist of mainly flat elements, in particular plates, in between which the stones can be provided, can be pushed through respectively, whereby at least one of these elements is provided with driving means, such that one or both of these elements are moved such that the stones provided between these elements are beaten back and forth between the elements.
  • the method according to the invention mainly consists in that the stones 1 to be distressed are provided in a suitable device 2 between two elements 3-4, in between which they are beaten, in this case beaten back and forth, by making one or both of the elements 3-4 carry out a certain movement, in particular a vibratory movement.
  • a certain movement in particular a vibratory movement.
  • the elements 3 and 4 preferably consist of flat elements, in particular plates, which extend parallel or almost parallel in relation to one another.
  • the stones 1 can be handled one by one or in groups. In the latter case, the stones 1 are preferably handled per layer 5 formed of stones 1 laid next to one another.
  • the method is preferably carried out as a feed-through process, by which is meant that the stones 1 are pushed between the elements 3-4 on one end 6, and are removed from between the elements 3-4 on the other end, in this case the opposite end 7, after they have been processed.
  • the feed-through can be carried out continuously or in steps.
  • the movement of the stones 1 can be realized according to several possibilities, a number of which are represented in figures 2 to 4.
  • one element in this case the element 4, is held still while the other element 3 is moved back and forth, in this case up and down, in relation to the fixed element 4.
  • the stones 1 provided between the elements 3 and 4 are thrown up and down between the elements 3 and 4 due to the vibration, so that pieces will break off the stones 3 and 4 due to the forces of impact exerted on the stones 1.
  • both elements 3-4 are moved back and forth, in particular up and down, preferably with a vibratory movement.
  • the elements 3 and 4 are moved in relation to one another according to opposite movements, in other words, the elements 3 and 4 are intermittently moved away from one another and back to one another.
  • the elements 3 and 4 are kept at a constant distance from one another, and they are moved simultaneously, so that the stones 1 are swung up and down between these elements 3-4, so that the aimed effect is also obtained.
  • measures are preferably taken which restrict the lateral tilting of the stones 1 between the elements 3-4 and/or prevent the stones 1 from shifting or rolling over one another.
  • the distance D between the elements 3-4 always has to be smaller than twice the thickness D1 of the stones 1 provided in between.
  • the stones 1 are preferably provided such between the elements 3-4 that their smallest distance extends in a direction perpendicular to the sides of the above-mentioned elements 3-4 which are directed to one another.
  • the device 2 for realizing the above-mentioned method may actually consist of two elements 3-4, in particular plates, in between which the stones 1 can be beaten back and forth.
  • FIGS 5 and 6 schematically represent a variant of this embodiment 2.
  • the element 4 is hereby provided with profilings 8 on the bottom side, in particular thickenings, to promote that pieces are beaten off the stones 1.
  • profilings 8 may consist of material thickenings.
  • the stones 1 and the profilings 8 are situated opposite one another, such that the profilings 8 are situated opposite one or several of the angles of the stones 1.
  • the device 2 may be equipped with guides 9-10 which offer a lateral guidance and/or support to the stones 1.
  • these guides 9-10 consist of struts which are fixed to the element 3.
  • the guides 9 and 10 make sure that the stones 1 cannot leave the device 2 sideways and also that they remain in an orderly position. When profilings 8 are used, these guides 9-10 also make sure that the stones 1 remain positioned correctly in relation to these profilings 8.
  • the far ends 6 and 7 can be equipped with supports which keep the stones 1 more or less in place. These can be removable supports 11 and 12 which are situated in the places indicated in figure 6 in the position in which they are provided.
  • Figure 7 schematically represents a variant of the device 2 in which the elements 3-4 are erected with a fall, which offers the advantage that the supplied stones 1 automatically vibrate through the device 2 from the one end 6 to the other end 7.
  • the element 3 hereby consists of a table which vibrates up and down.
  • the up and down movement is obtained by means of eccentric mechanisms 13 which are driven by means of a motor 14 and which consist of bearings 15 or such which are eccentrically fixed on shafts 16 which are driven in turn by the motor 14 via transmissions 17, whereby supporting arms 18 are provided on these bearings 15 onto which the table is fixed by means of hinge points 19.
  • the table is prevented from tilting down by means of a hinged joint 20 with a support 21.
  • the element 4 consists of a fixed plate which is attached to supports 22.
  • the eccentricity E is preferably selected such that it is smaller than half the thickness D1 of the stones 1. Moreover, the largest possible distance D between the elements 3 and 4 should preferably be smaller than twice the thickness D1, but the smallest distance D should be larger than D1.
  • the device 2 can be realized such that a number of parameters of the movements of one or both of the elements 3-4 can be adjusted and/or set.
  • the vibration speed can for example be adjusted by controlling the motor 14 either with or without a speed regulator 23.
  • the above-mentioned elements 3-4 can form a whole.
  • the device 2 may for example consist of a tube with a rectangular section through which the stones 1 are pushed, while this tube is moved to and fro with a vibrating movement, diagonally to its longitudinal direction.
  • the two above-mentioned elements 3-4 are formed of the two opposite walls of the tube respectively.
  • This tube may hereby be made such that the stones 1 can only be pushed through it one after the other, or it can also be made such that several stones 1 can be simultaneously pushed through it one next to the other.
  • the invention is particularly suitable and advantageous when used for distressing concrete stones. However, it is clear that it can also be used for other stones, such as for example bricks or natural stones.
  • the method will be preferably integrated in the production process or added to it at the end.
  • the stones 1, in this case the concrete stones, are formed in a first stage 25 by making concrete vibrate in a mould 26 by means of a suitable device 27 which is known as such and as a consequence is only represented schematically.
  • a suitable device 27 which is known as such and as a consequence is only represented schematically.
  • Several stones 1 are hereby simultaneously formed next to one another, preferably in a number which coincides with the number of stones 1 that is required to form a layer on a pallet.
  • the formed stones 1 are hardened in a natural or artificial manner. To this end, they are stored layer by layer, for example in a space 28 provided to this end. To this end, the stones 1 coming from the device 27 can be stacked on pallets 30 in this space 28 by means of an automatic transport device 29.
  • the concrete stones Once the concrete stones have sufficiently hardened, they are collected from the space 28 by means of the transport device 29 and they are carried to a device 2 according to the invention via a conveyor belt 31, after which they are exposed to a distress process as they are fed through said device 2.
  • the stones 1 remain neatly arranged, so that they can finally be taken up by means of a stacker 32 with a clamping system 33 and so that several layers can be piled one on top of the other so as to form a pallet 34 with a number of concrete stones stacked on it.
  • the distressing method according to the invention does not require the stones 1 to be completely hardened, which is indeed necessary when the stones 1 are distressed by means of a drum.
  • the stones 1, in the case of concrete stones, are preferably distressed even before they are five days old.
  • this period can be significantly reduced.
  • the stones 1 do not need to be stored any longer in the space 28 than is required now to harden and trade them.
