    DESCRIPTION
    Multi-wire frame for cutting blocks of stone material into plates.
    Field of the Invention
    The present invention relates to a multi-wire frame for cutting blocks of stone material into plates.
    In particular, the present invention relates to a frame for cutting blocks of stone material, such as granite, marble or the like. Reference will now be made to granite and marble, although such reference should not be construed as limiting the scope of protection of the present invention.
    State of the art
    The frames according to the prior art comprise a frame structure with two or four columns, which support the pulleys on which the cutting threads are arranged. The cutting threads are generally diamond threads.
    A first type of frame, called a two-column frame, comprises two columns that are normally connected at the top by means of a horizontal reinforcement beam on which respective pulley-bearing carriages slide vertically. The two cars are normally connected at the top by means of a connecting beam. One or more sets of pulleys, or one or more pulleys of multiple throats, on which the diamond threads are wound, are provided on the carriages.
    At least one of the rollers of multiple throats is a driving roller, while the rest of rollers of multiple throats are receivers.
    For a simpler reference and without a limiting meaning, from now on a reference will be made to a roller with multiple throats, this being also understood in the sense of a set of pulleys.

    In the prior art different arrangements of rollers of multiple throats and thread tensioning devices are known.
    Description of the invention
    In a first configuration, a roller with a large diameter, with threads arranged inside the respective throats, is mounted on each carriage, while the tensioning devices for each cutting wire are mounted on the connecting beam.
    In a second configuration, two rollers, with a smaller size diameter compared to the previous roller, are arranged vertically one above the other. The tensioning devices for the cutting threads are mounted on each carriage between the rollers.
    In a second type of frame, called a four-column frame, there are at least four columns arranged in the vertices of a rectangular base and normally connected at the top by two longitudinal beams that are connected to each other by two reinforcing crossbars. A car travels along each column. Two longitudinal elements, which are arranged parallel to each other, and two cross members that are arranged perpendicular to the longitudinal elements normally connect the carriages in pairs.
    The arrangement of the rollers is similar to that of the two-column racks, except for the fact that the rollers do not protrude from the frame, but are contained inside.
    The operation of the frame (either a two-column or four-column frame) is very simple: the operation of the multi-throated roller causes the movement of the cutting threads that are lowered over the block to be cut as a result of the Simultaneous downward movement of the cars along the columns.
    As is known, both the two-column and four-column frames are subjected to considerable effort, mainly the stress due to the tensioning of the cutting threads. In fact, each thread is properly tensioned with a force of
    5
    10
    fifteen
    twenty
    25

    35
    significant intensity, of the order of 250 kg. Considering for example a frame with forty threads, the overall tensioning force transmitted to the two columns is equal to approximately 20,000 kg, specifically a decidedly high value. In fact, due to the reaction, the forces applied to the columns are opposite to those applied to the diamond threads and are also directed towards each other, so that the columns tend to flex towards each other.
    Also, considering the two-column multi-wire frame, in which the pulleys are mounted protruding from the columns, the overall force by weight acting on the load bearing structure, mainly due to the weight of the mobile structure, tends to cause the frame turns to the side where the block is to be cut.
    In fact, considering the high weights involved and the large lever arm, and taking into account, as mentioned above, that there could be forty or even more cutting wires, the tipping moment is considerable.
    These loads subject the machine structure to a significant effort and therefore must be adequately compensated.
    Therefore, a tie rod is often provided for each column, placed on the side opposite to the block to be cut (and therefore on the side opposite the multi-groove rollers) fixed at one end to the ground and at the end opposite the top of the column, to counteract the overturning moment.
    In addition, the frame is subjected to an additional effort in the sense of the threads that is less than the force resulting from its tension. In fact, during the actual cutting operation, friction is generated between the wires and the block to be cut. Therefore, during the cutting, the diamond threads subject the rollers of multiple throats to an effort in the opposite direction to the direction of movement of the threads on the block to be cut, so that one of the two carriages is seen subjected to an effort by a force directed towards the outside of the frame, while the other car is subjected to an effort by a force that pushes it inwards.
    Obviously, in the racks of four columns there is no risk of overturning, although the machine is more complex and therefore more expensive and in any case the other loads

    acting on the structure (tensioning of the threads, weight of the mobile part of the structure, etc.) are still present.
    In order to oppose or counteract these forces, it is necessary that the cars are properly supported and guided along the columns.
    In addition, the frame must also be sufficiently rigid so that it does not deform excessively to facilitate the cutting operation and make a precise cut.
    Therefore, the most important characteristics are the structure of the car and the columns as well as the ways in which the car is supported and guided along the columns, since the forces involved are transmitted from the mobile part to the fixed part precisely through the cars that move along the columns.
    The prior art cars are complex structures, very resistant and very rigid, often equipped with a large number of wheels that move along the columns. They are mainly of the closed type around or covering the corresponding column to be able to withstand the high loads acting on them, which subject the frame to an effort in several directions, as mentioned above.
    In addition, they should also be able to limit the deformations to which the frame is subjected.
    Instead, the columns can have various configurations and are designed with a given profile along which the carriage guide wheels move vertically.
    The columns also have to be very resistant and rigid to be able to resist the efforts acting on them and limit any deformation as much as possible. The columns usually have a complex structure along which several guide rails are formed for the numerous carriage guide wheels.

    A possible column and carriage configuration will be described below according to the prior art for a two-column multi-wire frame.
    The column consists of a double T profile (for example IPE or HE), specifically with a central core that has two perpendicular wings fixed to its two ends. The upper part of the car comprises: four wheels that move along the inner part of the wings and another four wheels that move along the front end of the wings. Considering that this provision is repeated twice at different heights, the result is that each car has sixteen wheels and therefore the corresponding two-column multi-wire frame has up to thirty-two wheels.
    As mentioned above, all these wheels are necessary in order to guide the car along the columns, but in particular to oppose the efforts that act on the frame during the cutting operation.
    For example, the wheels that run along the inside of the wings of the profile are particularly opposed to the tipping moment generated by the weight of the moving structure since it presents a displacement with respect to the median plane that passes through the two columns.
    Instead, the guide wheels that run along the front ends counteract the reactive thrust resulting from the tensioning force applied to the diamond wires.
    According to the technique, some solutions are known that try to reduce the forces that act between the cars and the columns.
    In particular, in the case of two-column frames, a solution is known in which an arc structure is mounted to connect the protruding ends of the multi-groove rollers of the first carriage to the protruding ends of the multi-groove rollers of the second car. The arched structure is fixed on the beam that connects the two cars and therefore is mounted to protrude from said cars. Observing its configuration it can be understood that it can counteract, together with the connecting beam, the reactive force due to the tensioning of the cutting wires.

    Although the prior art is widely used and appreciated, it is not without its drawbacks.
    For example, it should be noted that in particular the system for guiding cars is quite complicated. In fact, it is necessary to provide a carriage structure that at least partially surrounds the column. The car must be provided with surrounding impellers or a large number of wheels and therefore a large number of components, resulting in its manufacture, assembly and maintenance or repair in the event of a malfunction being decidedly expensive and complicated.
    The columns also have a somewhat elaborate structure since they must have a suitable shape to allow the multiple impellers or wheels of the carriage to move along guide surfaces of varying direction with respect to each other.
    The objective of the present invention is therefore to overcome these drawbacks.
    A first purpose of the present invention is to provide a frame that presents simpler cars and columns resulting in lower manufacturing costs.
    A second purpose of the present invention is to provide a frame provided with cars having a simpler structure that can be easily accessed during maintenance or repair, with a more reasonable and simple lifting system.
    In addition, the purpose of the present invention is to provide a machine that is strong enough to withstand the forces acting on it and rigid enough to keep the cutting parameters as constant as possible during movement along the columns.
    The objective and tasks are achieved with a frame according to claim 1.
    In particular, the idea is to provide a multi-wire frame for cutting blocks of stone material, comprising: a first column and a second column that are connected at the top by a reinforcing crossbar, and first and second carriages that They are designed to slide over the first column and second column, respectively. The frame also comprises at least one

    multiple throats roller on each car, which is designed for coupling by means of cutting threads that extend between the first column and the second column, and a connecting beam between the first car and the second car. An arc structure is also provided on which the protruding ends of the rollers are mounted. Guiding means are also provided on the columns for sliding displacement of the carriages. The multi-wire frame is characterized in that it comprises laterally on each column a rail that is arranged in the vertical direction and provides guiding surfaces for the carriage guiding means.

    Detailed description of a form (s) of realization of the invention
    Figure 1 shows an example of a possible embodiment of a multi-wire frame for cutting blocks of stone material, indicated by reference number 12.
    The multi-wire frame 12 according to the present invention comprises: a first column 14 and a second column 16 which are connected at the top by means of a reinforcing cross member 18.
    As can be clearly seen in Figure 2, according to a possible embodiment of the present invention, to counteract the tipping moment, two braces 47, 49 are used, which are attached at one end to the ground and which are fixed by the other. end to the top of the two columns 14, 16.
    Advantageously, the two braces 47, 49 that connect the columns 14, 16 to the ground to counteract the tipping moment may not be rigidly fixed at their ends (one on the ground and the other at the end of the respective column), but which are articulated in an adequate manner, thus making the structure isostatic and thereby reducing the stresses and deformations that act on them.

    Each column is provided with a carriage: a first carriage 20 for column 14 and a second carriage 22 for column 16, which are designed to slide on columns 14, 16. The vertical movement of carriages 20, 22 can occur from in a manner known per se, for example by means of an endless thread / screw, recirculating or sliding bearing coupling. Advantageously, hydraulic oil compensation cylinders can be provided for each car in order to counteract the weight of the moving structure so that efforts are reduced.
    According to a possible embodiment of the present invention, shown in Figure 10, the vertical movement of the carriages 20, 22 can be carried out by means of hydraulic oil cylinders 23 in a manner known per se.
    The first carriage 20 and the second carriage 22 can be connected to each other by means of a connecting beam 24. The connecting beam 24 guarantees a rigid and synchronized movement of the first carriage 20 and the second carriage 22 during the cutting operation.
    According to a possible embodiment of the present invention, the carriage 20 is provided with at least two rollers with multiple throats 26, 28 that are designed to engage cutting threads that extend between the first column 14 and the second column 16, while similarly the second carriage 22 is provided with at least two rollers with multiple threads 30, 32 that are designed to engage cutting threads that extend between the two columns 14, 16.
    The rollers 26, 28, 30, 32 are provided on the carriages 20, 22 so that they can rotate about their axis of rotation A (shown in the example of Figure 3).
    As can be clearly seen in Figures 1 and 3, the rollers of multiple throats 26, 28 and 30, 32 have smaller dimensions and are arranged vertically one above the other. Tensioning devices 34, 36 (which can be seen in Figure 1) for the cutting threads are mounted on each carriage 20, 22 between the two rollers 26, 28 and 30, 32, respectively.
    In an alternative configuration (not shown in the attached figures), a single roller of multiple throats with a large diameter, which has threads arranged inside the respective throats, is mounted on each carriage 20, 22, while
    5

    fifteen

    25
    30
    35
    The tensioning devices for each cutting wire are mounted on the connecting beam and therefore in a higher position.
    Tensioning devices 34, 36 will not be described further since they are known to the person skilled in the art.
    According to a possible embodiment of the present invention, an arc structure 38 (or support structure) supporting the rollers 26, 28 and 30, 32 extends from the two carriages 20, 22 and from the connecting beam 24.
    As can be clearly seen in Figure 2, the arched structure may be formed by a central cross member 40 that is fixed protruding on the connecting beam 24 and by two arms 42 and 44 extending downwardly from the ends 46, 48 of the central crosspiece 40 and on which the protruding ends of the multi-groove rollers 26, 28 and 30, 32 are connected.
    According to a possible embodiment of the present invention, each roller 26, 28 and 30, 32 is keyed on an associated tree (not shown), the ends of which are engaged with the carriage 20, 22 and the arched structure 38. Advantageously the ends of the trees that are mounted on the ends of the arms 42, 44 of the arch structure 38 can be provided with damping elements or "silent blocks." The function of the silent blocks is to dampen the vibrations due to the action cutting
    Advantageously, as shown in FIG. 3, a first roller 28 may be inserted between the lower part of the first carriage 20 and the lower free end of the respective arm 42 of the arched structure 38, and a second roller 30 may be inserted between the upper part of the carriage 20 and the upper part of the arm 42 of the arch structure 38. The arrangement described above is advantageously repeated also for the second carriage 22.
    According to a possible embodiment of the present invention, the tensioning devices 34, 36 for the cutting threads are fixed between the two rollers 26, 28 and 30, 32.
    Due to the arc structure 38, when the cutting wires are tensioned, approximately half of the reaction forces generated by the tensioning of the wires are transmitted
    5
    10
    fifteen
    twenty
    25
    30
    35
    on the arched structure 38 and about half are transmitted on the two cars 20, 22.
    More precisely: a first pair of forces directed towards each other is applied at the points where the tensioning devices are connected to the two arms 42, 44 of the arched structure 38, and a pair of forces also directed towards each other. another is applied at the points where the tensioning devices are attached to the two carriages 20, 22. The arc structure 38 is opposed to the first pair of forces, while the second pair of forces tends to move the two carriages 20, 22 towards one another mainly opposes the connecting beam 24 which therefore acts as a brace.
    As a result, the frame, due to the arched structure 38, is released from the considerable efforts acting on it, thus also allowing the structure of the columns 14, 16 and the carriages 20, 22 to be simplified.
    With reference to the embodiment shown in Figure 6, which shows a cross section through a column 14, 16, it can be seen that the cross section can have a box-like shape.
    A rail 50 providing guiding surfaces 502, 504, 506 for guiding means 56 for carriages 20 is mounted on column 20. These guiding surfaces 502, 504, 506 are visible in Figures 4 and 6. Of Similarly, a rail 52 is mounted on the column 22, said rail providing guiding surfaces 522, 524, 526 for guiding means 58 for carriage 22. These guiding surfaces 522, 524, 526 are visible in the figures. 1 and 7.
    Advantageously, the rail (50, 52) can be a prismatic profile applied to or formed as a piece on a side face of the associated column.
    For reasons of convenience, reference will be made to a prismatic profile.
    Advantageously, the prismatic profile 50, 52 has a rectangular cross section, with one side that is fixed to the respective column 14, 16, and with the other sides forming the guiding surfaces 502, 504, 506 and 522, 524, 526.

    According to a possible embodiment of the present invention, the prismatic profiles 50, 52 are fixed respectively to the surfaces of the columns 14, 16 directed towards the inside of the frame (specifically the surfaces of the two columns facing each other). As will be evident below, the prismatic profiles, according to an alternative embodiment of the present invention, can also be fixed on the opposite surfaces of the two columns 14, 16, specifically the surfaces directed towards the outside of the frame.
    In both cases, the prismatic profile 50 therefore has an anterior guiding surface 506 and two lateral guiding surfaces 502, 504 along which the guiding means 56 of the carriage 20 move slidably along the columns 14. Similarly, the prismatic profile 52 therefore has an anterior guiding surface 526 and two lateral guiding surfaces 522, 524 along which the guiding means 58 of the carriage 22 slide slidably length of columns 16.
    For a simpler description, only the guiding means 56 of the first carriage 20 will be described, it being understood that the same characteristics are also present in the guiding means 58 of the second carriage 22.
    With reference to Figures 4 and 5, the guiding means 56 for a sliding movement of the carriage 20 along the column 14 comprise a first sliding unit 60 and a second sliding unit 62. The first unit 60 is connected to the carriage 20 in a lower position with respect to the second unit 62 and rests on a first lateral guidance surface 502 directed towards the rollers of multiple throats 26, 28. The second unit 62, connected to the carriage 20 in a superior position with respect to the First unit 60, rests on a second lateral guide surface 504 opposite the first lateral guide surface 502. The upper unit is on the side of the glutton opposite the cutting structure with the threads. In this way, the tipping torque produced by the weight of the structure is compensated by the two units 60, 62 that rest on the respective guiding surfaces.
    According to a possible embodiment of the present invention, shown in Figure 13, the lateral guide surfaces 502, 504 do not extend over the entire length of the profile, but only by a section thereof. In particular, the guiding surface 502 can extend from the base to a height corresponding to approximately the
    5
    10
    fifteen
    twenty
    25
    30
    35
    total height minus the distance between the two sliding units, while the guiding surface 504 can extend from the upper end to a height corresponding to the total height minus the distance between the two sliding units. The same processing principle can also be applied to the guiding surfaces 522, 526 of the guiding means 58.
    Advantageously, each sliding unit comprises one or more wheels that move along the respective guide surface.
    In particular, the sliding units can be advantageously formed as tilting units 60, 62 which are respectively provided with two wheels 601, 602 and 621,622 in each case and are pivotally mounted on the carriage 20.
    The first tilting unit 60 is connected to the carriage 20 in a lower position with respect to the second tilting unit 62 and has wheels 601, 602 that move along a first lateral guide surface 502 directed towards the rollers of multiple throats 26, 28. The second tilting unit 62, which is connected to the carriage 20 in an upper position with respect to the first tilting unit 60, has wheels 621, 622 that move along a second opposite lateral guide surface 504 to the first lateral guide surface 502.
    As can be clearly seen in the enlarged detail of Figure 5 and more particularly in Figure 8, in which the tilting unit 62 is shown, both tilting units can have a triangular shape in which the two wheels 621, 622 are provided in the vertices of a base and a hole 623 is provided in the opposite vertex, a pivot pin 624 mounted on the carriage (see Figure 5) being inserted inside said hole to allow rotation of the tilting unit with respect to the pivot pin shaft 624.
    Advantageously, the tilting units 60, 62 rotatably connected to the respective carriage 20, 22 allow the wheels 601, 602 and 621, 622 to better adhere to the prismatic profile 50, 52.
    The pivot pin 624 can be eccentric so that the hole 623 can move with respect to the rotation of the pivot pin 624 to allow adjustment of the
    5
    10
    fifteen
    twenty
    25
    30
    35
    position of the tilting units 60, 62 with respect to the prismatic profile 50, 52, so that the wheels 601, 602 and 621, 622 rest perfectly on the prismatic profiles 50, 52.
    The two sliding units or tilting units 60, 62 can counteract the tipping moment caused by the weight of the mounted mobile structure protruding from the two columns 14, 16.
    As can be seen from FIG. 5, the guiding means 56, 58 for sliding sliding of the carriages 20, 22 on the columns 14, 16 also comprise for each carriage 20, 22 end-guiding means 64, 66 that move along the leading guide surfaces 506, 526 that are directed opposite to the two carriages and therefore to the inside or outside of the frame (in the direction of extension of the threads between the carriages). Advantageously, in the embodiment shown, they are directed towards the inside of the frame 12.
    According to a possible embodiment of the present invention, the end guiding means 64, 66 can be two in number for each carriage 20, 22, being preferably arranged vertically displaced along the glues. Advantageously, each of the end guiding means may be arranged near each tilting unit 60, 62, as can be clearly seen in Figure 5 and Figure 13.
    Each of said end guiding means 64, 66 may comprise a single wheel 68, 70 that travels along the front guiding surface 506, 526.
    The end guiding means 64, 66 are designed to absorb the force acting in the direction of the threads. As already mentioned, the force is due to the actual cutting operation due to the friction generated between the wires and the block to be cut. During the cutting operation, the diamond threads subject the rollers of multiple throats 26, 28, 30, 32 to an effort in the opposite direction to the direction of sliding of the threads on the block to be cut. One of the two carriages 20 or 22 is subjected to an effort by a force directed towards the outside of the frame 12, while the other car is subjected to an effort by a force that pushes it inwards.

    Therefore, the only wheel of the carriage end guide means that is pushed outwardly is pressed against the front guide surfaces, while the only wheel of the carriage that is pushed inward tends to separate from the previous guide surface. and therefore not to perform its function correctly.
    To oppose this pair of forces, according to a particular embodiment of the present invention, the only wheels 68, 70 are mounted with a damping element 72 and a prestressing device 74 arranged in between, as shown in Figure 9 ( in which only the end guide means 66 are shown for a simpler illustration).
    Advantageously, in the case of wheels that tend to press against the anterior guide surface, a damping element made of very hard elastomeric material designed to resist compression can be used to undergo slight deformation, such as a cross-linked polyurethane. Instead, in the case of the opposite wheels, which tend to separate from the anterior guiding surface, a damping element made of soft elastomeric material, such as rubber, can be used so that by means of the prestressing device, it can be compressed . Thus, when the wheels of the end-guiding means tend to separate, the material, due to its elastic return movement, forces the wheels to always remain in contact with the surface.
    In addition, it will be noted that, unlike the guidance systems according to the prior art, the frame and in particular the cars according to the present invention are isostatic systems and are no longer hyperstatic systems. Consequently, stresses and deformations are significantly reduced.
    According to a possible embodiment of the present invention and as shown in Figures 11 and 12, the multi-wire frame comprises a safety device 80 that blocks the carriages 20, 22 along the columns 14, 16 in the case of a malfunction or breakdown of the devices that move the cars 20, 22.
    The safety device 80 advantageously comprises a set of teeth or a rack 82 along each of the two columns 14, 16 with which a ratchet 84 driven by a pneumatic cylinder 86 can be engaged against the action of a spring (not shown).

    In particular, the ratchet 88 is connected to the respective carriage 20, 22 rotatably at a point located between its ends 88, 90, in which:
    - a first end 90 is designed to engage with the rack 82, and
    - a second end 88 is connected with a rod 92 that is pushed down by a spring that is compressed and also articulates with the free end of the rod 87 of the pneumatic cylinder 86 which in turn is assembled in an articulated manner.
    In the resting position, shown in Figure 12, the spring is compressed and pushes the rod 92 and therefore the second end 88 of the ratchet 84 down and, consequently, causes the first end 90 to engage within the rack. 82, blocking carriage 14.
    In an operative position, the pneumatic cylinder 86 is operated so that the rod 87 leaves the cylinder, the second end 88 of the ratchet 84 is raised and its first end 90 is disengaged from the rack 82, thereby allowing the carriage to move 14.
    In an emergency, the power supply to the cylinders is interrupted so that the spring moves the ratchet back to the rest position, preventing any movement of the carriages.
    Therefore, the advantages of the present invention are apparent in comparison with the prior art.
    The frame according to the present invention is provided with carts and columns that are simpler and allow a reduction in manufacturing costs to be achieved.
    In addition, due to the simple construction design of the cars, the structure can be easily accessed during maintenance or repair.
    Obviously the above description of a form of realization that applies the innovative principles of the present invention is provided by way of example of these
    Innovative principles and therefore should not be considered as limiting the scope of the rights claimed herein.
    The person skilled in the art, to satisfy specific requirements, can make 5 modifications in the embodiments described above and / or replace parts described by equivalent parts, without thereby departing from the scope of the appended claims.
    For example, as will be obvious to the person skilled in the art in the light of the present description, it is possible to apply the solution described above also in the case of
    Four column racks. In particular, it is therefore possible to use the carriages and carriage guiding means described above also in the case of four-column racks, with similar benefits. In a manner similar to that described above for the solution of two columns, the lower tilting unit will run along a surface arranged towards the rollers, while the upper swinging unit will run along an opposite surface.
    Obviously it is also possible to provide a single roller with multiple throats for each car, with tensioning devices located on the connecting beam of the cars. 20 As already mentioned above, the sliding units can also each comprise a tilting unit system of a single wheel instead of one of two wheels. In addition, prismatic glues can be located on the external side of the columns, specifically on the surface of the columns directed towards the outside of the frame, with the consequent specular inversion of the guiding means (as for example the expert can easily imagine in the matter by figure 6).
