Definitions

  • This invention relates to a machine tool and in particular to a grinder for machining operations on sheets of glass and the like.
  • a first type of machine comprises the so-called rectilinear grinders in which the sheet being machined is kept in a substantially vertical position and moved forward, using a suitable transport system, on a train of cup grinding wheels, which vary in number according to the type of machine, having the axes of rotation also substantially vertical.
  • the grinding wheels machine one edge of the sheet at a time, for example polishing it, after which the sheet is rotated, usually manually, to progressively position all the edges on the grinding wheels for the respective machining operations.
  • Another type of reference machine is the bilateral machine in which the sheet, which is substantially horizontal, is moved forward along a corridor delimited at the sides by two series of cup grinding wheels having axes of rotation also substantially horizontal, which vary in number according to the type of machine, that machine two edges of the sheet at a time.
  • these machines comprise a conveyor of the sheets, kept substantially vertical, and a machining station with a vertical extension comprising at least one head and three axes on which the grinding wheels required by the machining are mounted in succession.
  • the sheet is moved forward, in a feed direction, to the machining station where each grinding wheel acts on the front edge of the sheet, considering the feed direction. Successive forward movements of the sheet and/or of the head allow the head to machine the upper edge, the rear edge and the lower edge of the sheet.
  • the vertical machines are also, as known, equipped with hole drilling tools which are able to operate on the two opposite faces of the sheet if two opposite heads are provided.
  • Such apparatus is provided for rotating and stropping a glass plate by 90 degrees by a rotary suction cup and for moving the rotary suction cup and the glass pplate linearly in every stop states, so that a straight edge at the lower end of the glass plate rotated and positioned in parallel with the linear movement direction can be ground by passing same through a grinding wheel.
  • an auxiliary suction cup for sucking and fixing the glass plate and moving linearly together with the glass plate is disposed at a position near the inner side, through which the grinding point of the grinding wheel passes.
  • the rectilinear grinders allow standard machining operations, for example polishing, on the side which passes above the grinding wheels and require the manual rotation of the sheet to operate on all the sides.
  • grinders are not able to make recesses, holes or slots, which are normally provided in the production of doors and the like for handles and hinges.
  • the bilateral machines are very bulky and require tipping of the sheets which are normally stored vertically.
  • the vertical grinding machines are, as mentioned, equipped with peripheral grinding wheels.
  • the polishing of the edges obtained with these grinding wheels is not appreciated in the more valuable products in which the better quality polishing obtained with the cup grinding wheels is preferred.
  • the productivity is limited due to the need to change the tools during the machining.
  • the rectilinear grinders do not allow the squaring and checking of the nominal dimensions of the sheets being processed.
  • the main technical purpose of this invention is to provide a machine tool designed in particular for the machining of sheets of glass and the like that is free of the above-mentioned drawbacks.
  • One aim of this invention is to provide a machine tool which is more versatile than rectilinear grinders and vertical machines.
  • the numeral 1 indicates a machine tool according to the present invention.
  • the machine tool 1 is preferably designed for machining sheets of glass 2 or the like having at least one edge 3.
  • sheet means a solid piece of material characterised by a thickness considerably less than the length or width.
  • the machine 1 comprises a frame 4 supporting the sheets 2; the frame 4, of substantially known type, is designed for supporting the sheet 2 in a substantially vertical position.
  • the frame 4 has a main direction of extension X which identifies, as explained below, a direction X of movement of the sheet 2.
  • the sheet 2 is moved on the frame 4 according to a feed direction V.
  • the frame 4 is equipped with a succession of rollers 5, extending in the direction X and positioned beneath the frame 4, on which the sheet 2 to be machined rests.
  • the frame 4 is equipped with wheels, not shown, having substantially vertical axes of rotation, which facilitate the translation of the sheets in the direction X.
  • the supporting surface of the sheet 2, defined by the above-mentioned frame 4 is, as is customary, inclined by 5° to a vertical lying plane.
  • rollers 5 are motor driven for feeding the sheet 2 along the direction of movement X and form means of moving the sheet 2.
  • the machine 1 comprises a machining station 6 at which predetermined machining of the sheet 2 is performed.
  • the machining station 6 is preferably located in an intermediate portion of the frame 4 in the direction X and the above-mentioned movement means allow the sheet to be taken and moved on the frame 4 along the direction X towards and away from the machining station 6.
  • the machine 1 comprises operator means for performing the machining operations at least on the edge 3 of the sheet 2, or substantially at it, in the machining station 6.
  • the operator means comprise a first train of tools 7, for example cup grinding wheels, and a second train of tools 8, for example peripheral grinding wheels.
  • the operator means are positioned beneath the frame 4 and the edge which is machined is the lower edge, observing for example Figure 5 , of the sheet 2.
  • the machine 1 only comprises the train of tools 7 or the train of tools 8.
  • first carriage to cup grinding wheels and for the second carriage to peripheral grinding wheels or ball-end milling cutters or the like.
  • the train 7 comprises one or more peripheral grinding wheels for example for rounding the corners of the sheet 2.

  • the train 7 comprises, schematically, one carriage 11 and a plurality of tools 12 on the carriage 11.
  • the numeral 12 denotes the pindles for actuating the corresponding tools, of substantially known type and therefore not described further.
  • the numeral 12a denotes the motors for actuating the spindles 12.
  • the train 8 comprises, schematically, one carriage 13 and a plurality of tools 14, preferably actuated by the heads 9, 10, on the carriage 13.

  • the pickup means of the station 6 are also indicated as rotary pickup means.
  • the machine tool 1 thanks to the pickup means in the machining station 6 rotatable about the rotary axis R, is able to rotate the sheet 2 being machined in such a way that the edge 3 to be machined can always be positioned below and can be machined using the tools 12, 14 on the carriages 11, 13.

  • the computerised unit 16 allows the interpolation of the movements of the sheet 2 and of the tools of the trains 7 and 8 both for verifying and recovering the expected shape and dimensions of the sheet and also for compensating the consumption of the tools or the dressing of the tools.

  • the sheet 2 can be moved forward as described above as far as the suction cup 15.
  • the suction cup 15 picks up the sheet 2 and thanks to the possibility of rotation about the axis of rotation R and the possibility of translating along the direction Y, suitably interpolated, by the unit 16, allows the machine 1 to perform machining operations also on edges for example curved.
  • the proposed solution is faster as tool changes are not necessary for polishing the edge; once the edge to be machined is positioned, if necessary by suitable rotations of the shaft, the train of grinding wheels, which carries all the grinding wheels necessary for the machining operations, performs the machining for each edge after the respective rotations.
  • the automatic rotation of the sheet not only increases productivity but also makes the machine safer than prior art solutions as the rotation of the sheet is not performed manually by an operator who would be in a danger zone.
  • the presence of the supporting system in combination with the rotary axis suitably controlled in combination with the tools allows performance of the machining operations also on sheets having edges which are not rectilinear, for example curved, that is, it renders the machine more versatile and not limited to machining operations on square or rectangular sheets.
