Definitions
- the invention relates to a apparatus for cutting stones, such as marbles, granites or the like, and particularly for cutting thin slabs or slices from thicker slabs, which comprises at least one cutting device having at least one endless flexible diamond impregnated tool.
- the invention also relates to a method for making laminate panels having at least one substrate layer and at least one covering layer joined together, the covering layer consisting of a thin slab or slice made of a stony material.
- the need to cut thin slabs or slices having a very small thickness from thicker slabs made of a valuable rock material, such as marble, arises from the need to reduce the amount and weight of such material in coverings and particularly from the need of covering support panels made of materials that combine stiffness properties to extra-lightness properties.
- These panels are typically used for external and/or internal wall covering of architectural structures of any type. When the panel is installed, the valuable material is exposed outside and the achieved aesthetic effect is identical to the one that might be obtained by using thicker stone slabs. All this is achieved at a considerably lower cost, and with a much easier installation, the covered panels being lighter and much easier to handle.
- the cut obtained thereby is limited in height, whereby processing widths are restricted due to the structural limits of prior art apparatuses.
- the width of the resulting slices is always considerably smaller than the width of the slab obtained by cutting the block.
- slabs are typically further sliced to obtain a useful width as allowed by the cutting width of the disks.
- prior art laminate covering panels have insufficient sizes or, when they are of the desired size, they are covered with smaller slices attached in adjacent positions.
- the resulting exterior appearance is obviously not the same as obtained by using slices having substantially the same size as those of the slab cut from the block and an additional processing step is anyway required.
- the wire guiding and supporting system only allows to cut slabs of the order of a few centimeters' thickness with an acceptable accuracy, but does not allow to perform cuts like those required to obtain extra thin slices.
- the vertical cutting direction is also not optimal, particularly with reference to the structural brittleness of the resulting slices.
- the means for feeding the slab in the cutting direction may consist of a movable bogie, running on rails, or of a roller track, but preferably consist of a conveyor belt having an essentially horizontal supporting surface. This belt is driven in such a manner as to feed the slab in the cutting progression direction, at a speed adapted to the cutting speed.
- the cutting device may include an endless, i.e. closed-loop diamond belt, which is driven in such a manner as to run in its longitudinal direction around two return pulleys, at least one being a driving pulley. Said belt is guided transversely and pressed in operating contact with the stone at the cutting line by a guiding and pressing horizontal blade. As is better explained below, said belt has a strong and durable construction and is also relatively cost-effective, though performing accurate cutting operations even ad high speeds, and thereby ensuring a high productivity.
- an endless, i.e. closed-loop diamond belt which is driven in such a manner as to run in its longitudinal direction around two return pulleys, at least one being a driving pulley. Said belt is guided transversely and pressed in operating contact with the stone at the cutting line by a guiding and pressing horizontal blade.
- said belt has a strong and durable construction and is also relatively cost-effective, though performing accurate cutting operations even ad high speeds, and thereby ensuring a high productivity.
- the blade may be substantially coplanar to the common horizontal plane of rotation of the return pulleys, which are arranged so that their axes of rotation are vertical. Its shape may be symmetrical with respect to its greater center axis, which is coincident with the line joining the centers of rotation of the pulleys.
- the blade may have two opposite longitudinal edges for slidably guiding the cutting diamond belt, the one turned toward the slab to be sliced and the other turned in the opposite direction.
- the blade has one single guiding and pressing edge turned toward the slab, corresponding to the active portion of the belt, whereas, in the other portion, the belt is guided in an intrinsically less accurate manner, e.g. on rollers or small pulleys.
- the blade is larger, at its center portion, and in the cutting direction, than the diameter of the return pulleys, whereas at the ends turned toward the pulleys it is substantially as large as the diameter of the pulleys. Thanks to this arrangement, the blade extends for a great portion of the cutting surface inside the slab and ensures an accurate and constant coplanarity of the two guided branches of the belt. This is particularly important to the purpose of cutting accuracy and in relation to the very small thickness of the slice to be obtained.
- the flexible endless diamond impregnated tool used in the inventive apparatus may be made in any manner fit for the purpose and may substantially comprise a flexible support closed-loop body, e.g. made of rubber or plastic.
- the tool has a flexible core, which may consist of one or more wires, typically twisted metal wires, but may also consist of an appropriate plastic material, embedded in the flexible material of the body.
- This body may include a succession of spaced metal segments, embedded therein and fixed to the body and/or the core, and having diamond impregnated surfaces which are conformed in such a manner as to project at least slightly out of the body of the belt, at least on its operating front surface, turned toward the slab to be cut.
- the shape, profile, arrangement of the diamond impregnated segments and the way they are fastened to the flexible support body may be selected in any manner, i.e. the best adapted to specific needs.
- the diamond tool assembly itself i.e. its flexible body supporting the diamond impregnated segments, may have any cross sectional profile.
- the body of the diamond belt may have, on its outer side, a substantially flat surface wherefrom the spaced diamond impregnated segments slightly project in the longitudinal direction of the belt, and are inserted in holes passing through the rigid segments, on the longitudinal wire/s of the core and partly embedded in the body.
- the diamond impregnated surface of each rigid segment may consist, for instance, of a corresponding sintered diamond impregnated element attached to the body of the rigid segment.
- the width of the segments may be slightly greater than the width of the body, so as to slightly project on one or both sides of the body, thereby forming a portion of the sharp edge of the respective longitudinal edge/s of the belt.
- the diamond belt may have, on its operating front surface, in coincidence with the intervals between the metal segments, transverse grooves, preferably joined at their ends to side grooves formed in the sides of the belt and extending on at least a portion of the belt height, to facilitate the flow of the cooling fluid and material removed from the stone in the cutting operation.
- the guiding and pressing blade may have a minimized thickness, as allowed by the mechanical and functional requirements of the blade and the diamond belt, and particularly it may have a slightly smaller thickness than the operating cutting thickness of the diamond belt, so as to minimize the sliding friction of the blade in the cutting direction.
- the blade may have a thickness of 6 mm, whereas the belt may have an operating cutting thickness of 8 mm, to determine a cutting width of 9 mm.
- the guiding and pressing blade may include at least one gap and/or at least one piping system, to be formed, for instance by milling, and to be connected to a source, particularly a pump, of pressurized fluid, particularly water. These pipes communicate with a succession of outlet ports appropriately distributed on the bottom of the two V-shaped longitudinal slide edges.
- pressurized water is injected between the guiding and pressing blade and the diamond belt, to form an anti-grip water cushion between the blade and the belt and, with a strong lubricating action, to control the temperature whereat cinders are removed from the cutting slot.
- the minimum thickness of the slab to be sliced may be such that, once the cutting thickness or width is deducted therefrom, two thin rock slices are obtained. These slices may have a thickness substantially of the order of a few mm to about two centimeters, and particularly of 4 to 6 mm. In the typical case of an intermediate slicing of a 20 mm thick slab, two 5,5 mm thick slices may be obtained.
- the guiding and pressing blade and the diamond belt return pulleys may be supported in a cantilever fashion at the bottom of a substantially horizontal beam or beam structure.
- Said beam is in turn supported in a slidable manner on at least one pair of vertical posts, provided each at an opposite end of the beam.
- Said beam also carries the means for rotatably driving the driving pulley, particularly a motor reducer.
- One of the return pulleys may be fitted on a stationary support to the beam, whereas the support of the other return pulley, particularly the idle pulley, may be mounted so as to slide horizontally on the beam and transverse to the cutting direction by means of appropriate actuators, so as to vary its distance from the support of the opposite return pulley and to adjust the diamond belt tension.
- control means may consist of at least one motor which acts on a drive, e.g. a worm which causes the upward or downward displacement of the beam.
- this invention also relates to a method for making laminate panels having at least one substrate layer and at least one covering layer joined together, the covering layer consisting of a thin slab or slice made of a stony material.
- the substrate layer may be made of any suitable material, either solid or having lightening apertures, particularly of one or more honeycomb materials, with open or closed, or partly open or closed cells. These materials may include, for instance, high density polystyrene, wood, particle boards, metal or rigid plastic grids or any other high stiffness and low elasticity material.
- the above method advantageously allows to directly cut stony material from a block, this arrangement being nevertheless an extreme solution.
- the preferred arrangement especially for workpiece handling reasons, includes precutting of blocks into a certain number of slabs of a predetermined thickness, particularly about 20 mm, covering the latter on both faces with substrate panels, and making an intermediate cut to obtain two identical panels covered with one 5,5 mm thick stone slice. It shall be noted that, even though the preferred application of the apparatus is intended to obtain thin slices, the apparatus may be advantageously used to obtain slabs having any thickness.
- the advantages of this invention are self-evident from the above description and consist in providing an apparatus as described hereinbefore, which allows to obtain a cutting width substantially equal to the width of the precut slab obtained from the block, and to obtain, in a single processing step, stone slices and panels covered with said slices, having a sufficient width. Thanks to all the above characteristics, especially to the fact that the diamond belt is guided by a rigid guiding and pressing blade on a well-defined cutting plane, and also due to the considerable surface of said blade, in the inventive apparatus, the diamond belt is allowed to cut in the best conditions and a high cutting accuracy is achieved, in combination with low noise and high cutting speed. Moreover, the method of the invention advantageously allows to provide the thin slice, during cutting operations, with a valid support element which prevents it from breaking and allows the direct production of laminate panels.
- the beam structure 5 carries a preferably metal blade 7 at its bottom, which blade extends horizontally and is fastened by its side ends to the beam structure 5 by cantilever support means.
- This blade 7 is as thin as possible in so far as the mechanical and functional requirements of the blade 7 itself and of a closed-loop cutting diamond belt 8 allow, which blade 7 acts as a guiding and pressing member in contact with the slab 3 in a horizontal cutting plane.
- a hinge connecting element 7 is provided at each of the two opposite side edges of the blade 7, which element is integral with the blade 7 on one side and is fitted in a cantilever manner to an element of the beam structure 5.
- one of the two hinge elements 107 is provided with means for adjusting the tension of the blade 7, consisting of a motor-driven actuator 207 which acts on a sliding slab 307, the hinge 107 being fitted on the edge thereof turned toward the blade 7.
- Both guiding edges 407, 507 are slightly arched outwards, with reference to the greater center axis of the blade 7 so as to ensure a perfect adherence of the two opposite guided parts of the belt 8 to the edges 407, 507 of the blade 7.
- the center portion of the blade 7 is very wide in the cutting direction, anyway larger than the diameter of the return pulleys 9, 9', whereas the ends thereof turned toward the pulleys 9, 9' are substantially as large as the diameter of the pulleys.
- the rotating shaft 109 of the idle pulley 9 may be drawn away from or closer to the rotating shaft 109' of the motor-driven pulley, in the direction transverse to the cutting direction, in such a manner as to control the tension of the diamond belt 8.
- Cutting operations are performed by running the belt 8 lengthwise thanks to its motor-driven return pulley 9', whereas the beam structure 5 is displaced in such a manner as to carry the blade 7 to the desired height relative to the slab 3, which is out of the cutting area, in this step. Then, the slab 3 is fed in the cutting direction thanks to the conveyor belt 4 at a uniform speed, which is adapted to the cutting speed.
