Definitions

  • the invention relates to a device and a method for processing shaped stones.
  • Machines for processing stones in particular for processing shaped stones made from cement or concrete, are known from the prior art.
  • the aim of the processing is to give the stones a quarry-like structure on at least one of their surfaces and to break the edges delimiting this surface.
  • Shaped stones in the sense of the present text generally have a cuboid structure, although a cube is of course also included in the term “cuboid structure”.
  • shaped stones are made in the shape of a parallelepiped, in the shape of a truncated pyramid or in the shape of a wedge. All of these characteristics have in common that the surfaces of the bodies are delimited by straight edges.
  • the “surface of a stone” and the “surface of a shaped stone” are understood to mean a surface delimited by straight edges, which is usually designed as a rectangle or square, but which in itself has a largely arbitrary shape can have.
  • Known machines for processing shaped stones always have a large number of tools that act like a hammer and are driven by, for example, a vibration drive for striking processing of the stones.
  • the stones are processed in the course of a relative movement between the stone to be processed and the processing machine, whereby the stone is moved relative to the stationary processing machine.
  • a processing machine with a rotating transport element which is designed as a wheel- or spoke-wheel-like element.
  • This wheel- or spoke-wheel-like element is arranged above the stone surface to be processed and rotates about an axis perpendicular to the plane driven all around the top of the stone layer.
  • Chains are held hanging on the transport element as processing elements, which strike against the surface of the stones or against the edges of the stones when the transport element rotates.
  • the transport element is moved over the stone layer.
  • the WO 02/096610 A1 describes a processing machine in which several drum-like elements driven around horizontal axes are provided in the transport direction of a conveyor belt on which the stones to be processed are moved one after the other through the processing machine. These drum-like elements are located above the path of movement of the stones to be processed and carry chains that strike against the surface of the stones to be processed or against the edges of the stones.
  • a processing machine for processing several stones arranged on a support and forming a stone layer in the area of the top of the stones.
  • the processing machine has at least one processing unit with at least one transport element that can be driven in a rotating manner.
  • a large number of processing tools for processing the stones are arranged on the rotating transport element.
  • the transport element is designed in the form of a chain which forms a self-contained loop which is arranged in a plane parallel or substantially parallel to the plane of the top side of the stone layer. The loop extends over the entire width of the stone layer in the axial direction of the loop.
  • the stones In addition to producing a quarry stone-like structure and breaking the edges, it is often also desirable for the stones to have a "bulgy" shape on at least one of their surfaces, i.e. that the stone surface in the area of an upper and a lower edge relative to the one in the middle between them The area lying on the edges recedes to the rear.
  • the edges of the stones should be rounded or slightly broken in a visually appealing way.
  • the invention is based on the object of providing a processing device for processing shaped stones, with the help of which a particularly visually appealing stone surface can be created and at the same time the stone can be given a bulbous shape.
  • the present invention relates to a processing device for processing shaped stones, wherein the processing device has at least one drive unit and at least one elongated shaft having an axis of rotation.
  • the shaft is designed in such a way that it can be set in a rotational movement about its axis of rotation by the drive unit.
  • At least three annular support elements that are firmly connected to the shaft are arranged on the shaft, with a first terminal support element being arranged on the shaft adjacent to the end of the shaft adjacent to the drive unit, and a second terminal support element being arranged adjacent to the end of the shaft facing away from the drive unit the shaft is arranged, and at least a third support element is arranged between the first end support element and the second end support element on the shaft.
  • At least two first processing tools are elastically attached to the first end support element, at least two second processing tools are elastically attached to the second end support element, and at least two third processing tools are elastically attached to the third support element.
  • Each of the processing tools has a processing head at its end spaced from the support element for interaction with a surface of the shaped stones to be processed.
  • Each of the machining tools also has a tool axis that is oriented radially outwards from the respective support element.
  • the first processing tools attached to the first end support element have a first extension in the direction of their respective tool axis
  • the second processing tools attached to the second end support element have a second extension in the direction of their respective tool axis
  • the third ones arranged on the at least one third support element Machining tools have an extension in the direction of their respective tool axis.
  • the first extent of the first processing tools is greater than the extent of the third processing tools and the second extent of the second processing tools are greater than the extent of the third processing tools.
  • a shaft is understood to be an elongated, cylindrical and rotating machine element that is used to transmit rotary movements and torques.
  • the processing tools are rotated about an axis.
  • the arrangement and movement of the processing tools has the advantage that the axis of rotation and thus also the direction of movement in which the processing tools act on the surface of the shaped blocks can be changed as desired.
  • the shaped stones are processed on at least one of their surfaces and on the edges delimiting this surface using the processing tools.
  • the processing tools are moved in a rubbing or scraping manner over the surface and edges of the shaped stone, in such a way that all the processed edges are arbitrarily broken by the processing tools and arbitrarily formed processing structures result on the surface.
  • the appearance of these processing structures can be changed by changing the angle between the axis of rotation of the shaft and the direction in which the shaped blocks are moved past the processing device. For example, if the axis of rotation of the shaft is perpendicular to the transport direction, the rotating processing tools act on the surface of the shaped blocks in a direction parallel to the transport direction. This allows a strip-like processing pattern to be created on the surface of the shaped bricks. However, if such a pattern is not desired, but an arbitrarily designed processing structure is preferred, the shaft of the processing device is always parallel to the surface of the shaped blocks to be processed, but is usually oriented obliquely to the transport direction of the shaped blocks.
  • the first processing tools attached to the first end support element have a first extension in the direction of their respective tool axis
  • the second processing tools attached to the second end support element have a second extension in the direction of their respective tool axis
  • those on the at least a third The third processing tools arranged on the support element point in the direction of their respective tool axis expansion.
  • the first extent of the first machining tools is greater than the extent of the third machining tools and the second extent of the second machining tools is greater than the extent of the third machining tools.
  • the first and second machining tools arranged in the region of the ends of the shaft protrude further away from the shaft than the third machining tools arranged in the central region of the shaft.
  • the longer processing tools arranged in the area of the ends of the shaft come into more intensive contact with the shaped stone compared to the processing tools arranged in the central area of the shaft.
  • This more intensive contact causes more intensive processing and thus an increased amount of material breaking out of the molded stone.
  • the processing tools attached to the end support elements are located in the area of the upper and lower edges delimiting the surface to be processed. The area of the edges is therefore processed more intensively than the central area of the shaped stone, which means that the desired bulbous shape of the stones is easily achieved in a high quality.
  • shaped stones can be processed in such a way that they have a visually appealing stone surface that is similar to a natural stone and at the same time have a bulbous shape.
  • two processing tools attached to one of the support elements are arranged in alignment with one another on the respective support element and the two processing tools each have a common tool axis.
  • the aligned arrangement means that the forces that occur when the processing tools act on the stone surface are distributed and dissipated most favorably.
  • Common shaped stones have a maximum height of 40 cm.
  • the entire surface of such a shaped block can be processed in the vertical direction by 11 support elements arranged one above the other in the vertical direction, i.e. a first end support element, a second end support element and 9 third support elements.
  • a single processing tool or a single support element preferably has an extension in the vertical direction of around 4 cm.
  • the design of the processing device according to the invention allows it to be carried out easily Adaptation to shaped stones of different dimensions. For example, if shaped stones with a height of 20 cm are to be processed, only 6 support elements with processing tools attached to them are attached to the shaft.
  • the bulbous shape of the stones achieved with the aid of the processing device according to the invention can be further improved if the third processing tools arranged on the various third support elements have a different extent in the direction of their respective tool axis.
  • the first extent of the first machining tools is greater than the extent of all third machining tools and the second extent of the second machining tools is greater than the extent of all third machining tools, the third ones arranged on the various third support elements
  • machining tools can have a different extent in the direction of their respective tool axis.
  • the third machining tools can have a greater extent in the direction of their tool axis, the closer or more adjacent the third support element carrying them is arranged to the first end support element or to the second end support element.
  • the third processing tools arranged on the two third support elements adjacent to the first end support element or the second end support element have a greater extent than those arranged on the middle between these two third support elements third support element.
  • the bulbous shape of the processed stones is further improved because the centrally arranged support element carries the shortest third processing tools.
  • the two support elements arranged subsequently in the direction of the ends of the shaft carry processing tools that are shorter than the first and second processing tools, but longer than the third processing tools arranged on the central support element.
  • the starting point is: In the central area of the stone towards its opposite edges, more and more material is broken out of the shaped stone, which leads to a more sculptural design of the stone and an improved bulbous shape.
  • the lengths of the third processing tools can be coordinated with one another as desired over a wide range. It is also conceivable to process the stone asymmetrically with respect to the central area of the stone, so that the curvature of the stone recedes more steeply towards one edge of the stone than towards the opposite edge. For larger stone surfaces, wave patterns could even be created if alternating longer and shorter third processing tools are provided. Further variants that are technically easy to implement are obvious to the person skilled in the art.
  • 4, 6, 8 or 10 or at least 4 or at least 6 or at least 8 processing tools are attached to each of the first, second and third support elements.
  • An increasing number of processing tools per support element is associated with increased energy expenditure for stone processing per time, but the surface of the shaped stones can be processed in a shorter processing time. An increased throughput of stones is therefore achieved.
  • third support elements are arranged on the shaft 8, with processing tools being attached to each of the first, second and third support elements 4. Test runs have shown that this combination of 8 support elements and 4 processing tools per support element has ideal properties in terms of speed and quality of surface processing.
  • the first, second and third processing tools have an elastic element at their end facing the respective support element.
  • an elastic element can consist, for example, of a vibration metal buffer. Due to the elastic properties of this element, the processing tool can be moved slightly out of its orientation along the tool axis when it acts on the surface of the shaped stone to be processed. When they come into contact with the shaped stone surface, the processing heads of the processing tools move along the shaped stone surface in a chiseling, scraping and rubbing manner, with elastic deformation of their elastic elements. In this way, the desired processing structures are achieved in high quality. Different appearances of the processed stone surface can also be achieved by using differently designed processing heads.
  • the elastic elements offer the option of adjusting the elastic deformation of the processing tools and thus the intensity of the processing in order to achieve the desired processing structure by appropriately placing the processing device relative to the transport device. Because the shaft when processing the shaped stones is arranged parallel to the surface of the shaped stones to be processed, the closer the processing device is placed to the transport device, the more intensive the processing tools come into contact with the shaped stone surface.
  • At least 3 third support elements are arranged on the shaft between the first end support element and the second end support element.
  • the first, second and third support elements are connected to the shaft in such a way that the intersection points of the tool axes with the shell of a straight circular cylinder, the cylinder axis of which coincides with the axis of rotation of the shaft, lie on one or more common helical lines.
  • a helix also known as a helix or helix, is a curve in 3-dimensional space that is created by a combination of rotation and translation along the axis of rotation.
  • Screw lines play an important role in depicting spiral staircases, threads and twist drills. Screw lines can be created using a tightly stretched thread between two points on a cylinder jacket. It is the shortest connection between two points on a cylinder surface.
  • the annular support elements are connected to the shaft in such a way that the intersection points of the tool axes with the shell of a straight circular cylinder, the cylinder axis of which coincides with the axis of rotation of the shaft, lie on one or more common helical lines.
  • the first, second and third annular support elements are preferably connected to the shaft in such a way that the intersection points of the tool axes with the shell of a straight circular cylinder, the cylinder axis of which coincides with the axis of rotation of the shaft, lie on one or more common helical lines.
  • This has the advantage that several processing tools do not come into contact with the surface of the shaped stone to be processed at exactly the same time. Since relatively large forces are transmitted to the shaped stones by the processing tools, a row of processing tools arranged linearly one above the other would cause the entire processing device, including the drive unit, to vibrate, which would cause significantly increased material fatigue. This is prevented by the helical arrangement of the machining tools around the shaft.
  • the first extent of the first machining tools and the second extent of the second machining tools are the same size. This makes it possible to process two opposite edges of a shaped stone in the same way. Since the material removal on both edges is essentially equally pronounced, a stone surface is created that is symmetrical relative to a horizontal plane. In this case, the bulbous shape of the stone runs forward from both opposite edges with approximately the same curvature.
  • the opposite edges are machined to different degrees.
  • a shaped stone surface can be formed in which one edge, for example, jumps forward relatively sharply at an angle of approximately 90°, while the opposite edge merges into the vertical stone surface, for example in a soft, slightly curved bend.
  • the first extent of the first processing tools and/or the second extent of the second processing tools is between 0.5 cm and 5 cm, preferably between 1 cm and 3 cm, larger than the extent of the third processing tools.
  • the longer processing tools attached to the end support elements come into more intensive contact with the shaped stone compared to the processing tools arranged in the central region of the shaft. This more intensive contact causes more intensive processing and thus an increased amount of material breaking out of the molded stone.
  • the entire processing device is always arranged in such a way that the third processing tools, i.e. the processing tools attached to the third support elements arranged between the end support elements, are also brought into contact with the stone surface. The entire surface of the shaped stone should be processed.
  • the present invention also includes a processing system for processing shaped stones, the processing system comprising at least one of the processing devices described above.
  • a transport device is provided for transporting the shaped blocks to be processed in a transport direction through a processing line.
  • the processing of the shaped stones with the aid of a processing device according to the invention takes place during a relative movement between the shaped stone to be processed and the processing device.
  • the transport device moves the shaped stone relative to the stationary processing device and processes it in the area of the processing line.
  • the processing device is arranged relative to the transport device in such a way that in the area of the processing section the processing tools with their processing heads come into operative connection with the surface of the shaped blocks to be processed.
  • the processing heads move with elastic deformation, for example of their elastic elements, chiseling, scraping and rubbing along the shaped stone surface and at the same time also capture all edges delimiting the respective shaped stone surface.
  • the transport device is preferably designed in such a way that the shaped blocks to be processed are arranged at least in the area of the processing section in such a way that the surface of the shaped blocks to be processed is oriented in a vertical or substantially vertical plane.
  • the processing device can be arranged so that its shaft also runs in a vertical direction. This makes installing the entire processing system the easiest.
  • At least two processing devices are provided, with at least one processing device being arranged in the horizontal direction on both sides of the processing line.
  • two opposing surfaces of the shaped blocks can be processed at the same time. Since the processed shaped stones are often used to build walls with only one layer of stone in the horizontal direction, it is often desirable for the shaped stones to have two opposing processed surfaces.

  • Processing system 10 shown has several processing devices 1.V1, 1.V2, 1.V3, 1.V4, 1.H1, 1.H2, 1.H3, with an equal number of processing devices on both sides of the processing path in the horizontal direction is arranged.
  • two opposing surfaces of the shaped blocks F can be processed at the same time. Since the processed shaped stones are often used to build walls with only one layer of stone in the horizontal direction, it is often desired for the shaped stones to have two opposing processed surfaces. This requirement can be efficiently met with the help of a processing system 10 with several processing devices 1.V1, 1.V2, 1.V3, 1.V4, 1.H1, 1.H2, 1.H3 arranged in the horizontal direction on both sides of the processing line .
  • the processing devices 1.V1, 1.V2, 1.V3, 1.V4, 1.H1, 1.H2, 1.H3 are attached to a schematically indicated frame.
  • the shafts of the processing devices 1.V1, 1.V2, 1.V3, 1.V4, 1.H1, 1.H2, 1.H3 are arranged so that the axis of rotation of the shaft runs parallel to the surface of the shaped blocks to be processed. From the Figure 5 It can be seen that the axes of rotation of the shafts of the processing devices 1.V1, 1.V2, 1.V3, 1.V4 enclose an angle ⁇ ⁇ 105° with the transport direction TR. Those arranged on the opposite side of the shaped blocks F Processing devices 1.H1, 1.H2, 1.H3 enclose an angle ⁇ ⁇ 75° with the transport direction TR (not shown). This orientation of the axes of rotation relative to the transport direction makes it possible to achieve particularly attractive surface structures. To set alternative angles between the shaft and the transport direction, the processing devices can be pivotally attached to the frame.
  • the shaped blocks F are arranged on the transport device T in such a way that their surfaces to be processed point vertically upwards. During processing, the shaped blocks F are secured against tipping over. Such protection against tipping over is particularly necessary when it comes to plate-shaped shaped stones that are transported upright through the processing line. For example, a height-adjustable guide can be provided as a safeguard, which prevents the shaped blocks from moving sideways or tipping over.
