Definitions

  • the present invention relates to a machine for cutting/ separating flat pieces of ceramic and the like, such as tiles, and other pieces used for flooring, glazed tiling and surfacings in general during construction.
  • the machine is of the type which comprises a sliding support which carries a tool for cutting or marking the flat ceramic piece, said cutting tool marking the piece with a groove, and further comprises a mechanism for separating said piece into two parts along said groove, said mechanism including a pair of feet which act against each of said parts which are to be separated and against a protruding element located below the piece in the region of the groove.
  • EP-A-0 387 142 discloses a machine for cutting and separating ceramic tiles comprising a sliding guide, a cutting assembly which can move along said guide provided with a cutting tool for marking the tile with a groove and a tile breaking member being integral with the cutting aseembly.
  • Said breaking member comprises a pair of legs being able to act on the tile surface for separating it in two parts and helped by a protruding element in the base of the machine and placed below the tile. The breaking member is operated by the same lever used for the cutting tool.
  • EP-A-0 255 460 is a machine which comprises a flat frame for supporting the piece to be cut, terminal support elements with two parallel fixed bars on wich a head slides, said head bearing a scoring tool being actuated upon lever operation, which also acts the breaking member in turn.
  • Said lever has a forward free end forming a protruding element which projects through an opening centered with the scoring axis.
  • the use of two independent elements, (cutter and breaker) means the piece must first be removed from the first element to be subjected to the operation of the second one.
  • the known devices especially as far as the manual type is concerned, are difficult to use with thicker ceramic pieces and are of no use with harder materials, such as stoneware or the like.
  • the static devices have the drawback that they too are designed for use in practice only with ceramic pieces of certain predetermined thicknesses and not with hard materials (stoneware and the like), which must still be cut either manually, with a disc part-off machine or with other devices which are more complicated to use and not always reasonably priced.
  • Said levers which are joined at their lower end by a spring, are actuated by a common cam which acts on the respective lower ends and which is controlled by a manual actuating lever.
  • the cutting tool is mounted on a cylindrical shaft joined to the sliding support.
  • the shaft is fixed to the support by the force exerted by the end of the actuating lever which is screwed to the support.
  • the tool handle has a cylindrical shape and is therefore liable to rotate about its axis of symmetry, and thus the tool can become incorrectly positioned.
  • known machines are provided with a device for positioning the piece to be cut.
  • positioning devices which comprise a fixed stop rule located at one end of the machine, an element which can be moved linearly along the length of a guide and a rotating element connected to the linearly movable element.
  • it is the fixed rule itself which guides the linearly movable element, the free end of said element forming an arc at the end of which the rotating element can pivot.
  • the rotating element has a stop plane which can be arranged in any angular position relative to the axis of symmetry of the machine and move along said machine by means of the linearly movable element.
  • the piece can be cut at any angle and with the piece at any position on the machine.
  • the piece is only supported in one plane (the stop plane of the rotating element) and its position cannot be guaranteed, since the piece may move when the operations of cutting and separation are carried out.
  • the machine for cutting/separating flat pieces of ceramic and the like which forms the object of the invention is of the type which comprises a sliding support bearing a tool for cutting or marking the flat ceramic piece; said cutting tool marking the piece with a groove; and further comprises a mechanism for separating said piece into two parts along said groove; said mechanism including a pair of feet which act against each of said parts which are to be separated and against a protruding element located below the piece in the region of the groove, and said separating mechanism forms an integral part of the same sliding support which bears the cutting or marking tool and is actuated by the same lever which is used for actuating said tool.
  • the sliding support comprises means for positioning the separating mechanism, said means enabling the separation feet to be arranged at two extreme positions, a high position above the cutting or marking tool, and a low position below said tool.
  • An object of the present invention is to provide means for positioning the separating mechanism which comprise a lever which includes a pair of arms which pivot on the sliding support, each one provided with a grooved cam in which slides a spigot which forms an integral part of each of said feet, said spigot being guided such that its movement is substantially vertical, the extreme positions, high and low, of the feet corresponding to the extreme positions of said spigots in the grooved cams.
  • Another characteristic of the invention is that the element protruding from the separating mechanism located below the piece is a rib provided along the length of the machine.
  • said rib is arranged between two surfaces which act as a support base for the flat piece of ceramic and which are deformed by the action of the feet of the separating mechanism such that the rib protrudes.
  • said rib can be fixed, thereby maintaining a high rigidity.
  • the machine of the invention comprises a stop rule which slides in a direction which is transverse to the movement of the sliding support and which rotates about a pivot point.
  • This rule enables the piece to be arranged at any location on the machine support and in any angular position.
  • the machine further comprises a pair of cylindrical bars along which the sliding support is guided, and a second pair of bars whose resisting moment to bending is greater than that of said cylindrical bars, said second bars being arranged below the cylindrical bars and embedded in the sliding support such that they can withstand the reaction of said support when the feet act on the piece, after the cylindrical guide bars have been slightly deformed.
  • the cylindrical bars carry out the function of guiding the sliding support but have a reduced resistance to bending. These second bars prevent the cylindrical bars from being deformed due to the strong forces produced when the piece is separated into two parts.
  • the machine which forms the object of the present invention is characterized in that the cutting tool is mounted on a shaft which comprises means for positioning the shaft relative to the sliding support.
  • the means for positioning the cutting tool shaft relative to the sliding support comprise at least one projection on the sliding support and at least one recess in said shaft, said projection and said recess being mutually coupled.
  • the projection or projections are formed on a bushing of hard material mounted on the sliding support.
  • the positioning device is characterized in that it comprises a fixed sector, graduated in angles, relative to which moves the rotating element, said rotating element comprising the guide along which moves the linear movable element, said linearly movable element being graduated along its length.
  • the linearly movable element is a graduated rule provided at its free end with a stop element which presents, on one side of the rule, a tail which is substantially perpendicular to said rule and, on the other side of the rule, an extension which presents a plane which is substantially perpendicular to the rule and remote from its free end, and a plane which forms a certain angle relative to the rule.
  • the pieces can thus be supported on two planes even when they are arranged at an angle to the axis of symmetry of the machine, thereby making it easier to ensure that they are correctly positioned during the operations of cutting and separation.
  • the device of the invention comprises means for fixing the position of the linearly movable element and means for fixing the position of the rotating element.
  • figure 1 is a side elevation view, in partial section, of the machine of the invention
  • figure 2 is plan view, also in partial section, of the same machine as figure 1
  • figure 3 shows a detail of the sliding support with the separation feet in the high position
  • figure 4 shows a detail of the sliding support with the separation feet in the low position
  • figure 5 shows a detail, in cross section, of the separation feet and the rib located below the piece

  • figure 7 is a plan view of a detail of the central part of the sliding support, showing one embodiment of the means for positioning the tool shaft on the sliding support
  • figures 8,9 and 10 show further embodiments of said positioning means
  • figure 11 is a detail of the positioning device with the rotating element in its rest position
  • figure 12 shows the same device as figure 11 with the rotating element away from its rest position
  • figure 13 shows the same device as figures 11 and 12 with the linearly movable element arranged especially for the positioning of pieces which have large dimensions.
  • the separation feet 4,5 form an integral part of the sliding support 1 which carries the cutting or marking tool 2 and are actuated by the same lever 6 which is used to actuate said tool.
  • Each of these arms 8,9 is provided with a grooved cam 10 in which slides a spigot 11 which forms an integral part of each of said feet 4,5.
  • This spigot 11 is guided by means of a block 12 in guides 13,14 such that its movement is appreciably vertical, the extreme positions, high and low, of the feet 4,5 corresponding to the extreme positions of said spigots 11 in the grooved cams 10.
  • a rib 15 can be seen arranged along the length of the machine.
  • Said rib 15 is arranged between two plates 16,17 which act as a support base for the flat piece of ceramic 3 and which are deformed by the action of the feet 4,5 such that the rib 15 protrudes and comes into contact with the piece 3 in order to carry out the operation of separating said piece.
  • Figures 1 and 2 show a stop rule 18 joined to a graduated rule 19 which can slide in the direction of the arrows A.
  • the stop rule 18 can also be rotated about a pivot point 20.
  • the same figures 1 and 2 show a pair of cylindrical bars 21,22 which guide the sliding support 1 and a second pair of bars 23,24 (only one bar is visible in each figure) which are rectangular in cross section.
  • the bars 23,24 are here rectangular in cross section but they could have any section which provides a resisting moment to bending greater than that of the cylindrical bars 21,22.
  • a groove 25 In order to separate a ceramic piece 3 into two parts, a groove 25 must first be made in said piece as shown in section in figure 5. Said groove is made using the cutting or marking tool 2 which is actuated by the lever 6 as shown in figure 3.
  • lever 7 To do this the lever 7 must be in the position shown in figure 3 such that the feet 4,5 are in the high position.
  • the piece 3 is separated into two parts by means of the feet 4,5 as shown in figure 4.
  • lever 7 must be in the position shown in figure 4 such that the feet 4,5 are in the low position.
  • Figure 6 shows the machine for cutting/separating which forms the object of the patent.
  • said machine comprises a sliding support 1 bearing a tool 2 for cutting or marking the flat ceramic piece 3, said cutting tool 2 marking the piece with a groove 25, and further comprises a mechanism 4 for separating said piece 3 into two parts along said groove 25.
  • the projection 31 is formed on a bushing 33 of hard material mounted on the sliding support 1.
  • the projection 31 and the recess 32 are triangular in section.
  • the shaft 30 has a plane 34 to which is applied the end of the actuating lever 6, which is screwed to the sliding support 1.
  • Figure 9 shows a further embodiment of the means for positioning the shaft 30 in the bushing 33, where the mutually coupled projection 31 and the recess 32 are semicircular in section.
  • Figure 10 shows another embodiment with three projections 31.
  • positioning means could be of any other shape.
  • said means could be the reverse, i.e. a projection or a number of projections on the shaft and a recess or a number of recesses in the sliding support.
  • the positioning device 107 which forms an object of the invention, which comprises a fixed stop rule 108, an element 109 which can be moved linearly along a guide and rotating element 110 connected to said element 109.
  • the positioning device comprises a fixed sector 111, graduated in angles, relative to which moves the rotating element 110, said rotating element 110 comprising the guide 112 along which moves the linearly movable element 109, said linearly movable element 109 being graduated along its length.
  • the linearly movable element is a graduated rule 113 provided at its free end with a stop element which presents, on one side of the rule, a tail 114 which is substantially perpendicular to said rule 113 and, on the other side of the rule, an extension 115 which presents a plane 116 which is substantially perpendicular to the rule 113 and remote from the free end thereof, and a plane 117 which forms an angle of 45° relative to the rule.
  • the device further comprises a lever 118 for fixing the position of the graduated rule 113 and a lever 119 for fixing the position of the rotating element 110.
  • FIGS 11 to 13 show various applications of the positioning device of the invention.
  • the positioning device can be seen applied to a piece 120 which has small dimensions.
  • the piece 120 is supported on two planes, i.e. the plane formed by the fixed rule 108 and the plane 116 of the extension 115, thereby ensuring that the piece is correctly positioned during the operations of cutting and separation.
  • the graduated rule 113 makes it possible to know the position accurately.
  • the position can be fixed for carrying out repeated cuts.
  • Figure 12 shows the positioning device also applied to a piece 122 which has small dimensions and which is to be cut at a certain angle.
  • the piece is again supported on two planes, i.e. the plane formed by the rotating element 110 and the plane 116 of the extension 115, thereby ensuring that the piece is correctly positioned.
  • the graduated rule 113 enables to know the position accurately, but now there is also an angular displacement which can be measured using the graduated angular sector 111.
  • the position of the positioning device 107 can be fixed by means of the levers 118 and 119.
  • Figure 13 shows the positioning device further applied to a piece 123 which has large dimensions.
  • the piece 123 is supported on two planes, i.e. the plane formed by the fixed rule 108 and the plane 124 of the extension 114, thereby ensuring as in the previous cases that the piece is correctly positioned during the operations of cutting and separating.
