Definitions

  • the present invention relates to a grinding head particularly for chamfering-profiling machines for glass plate elements.
  • grinders for machining and chamfering the edges of glass plates and the like are already present on the market; said grinders are substantially constituted by a table which supports the glass plate being machined and has an arm on which a mandrel or grinder support head can move along its axial direction so as to adjust the depth of the stroke. Said heads can furthermore rotate about an axis which is substantially tangent to the edge being machined, so as to adjust the angle or inclination of the chamfering being machined and can furthermore rotate about an axis which is substantially perpendicular to the extension of the edge being machined, in order to vary the inclination of the grinder portion which operates on the edge.
  • Manually actuated kinematic systems are currently used to axially move the grinder and allow to move said grinder to preset positions defined by manually adjustable tappets which engage an auxiliary shaft having a rack-like portion which meshes with a gear which in turn meshes with a rack-­like portion defined on the grinder supporting sleeve.
  • Said tappets must be adjusted in each instance so as to define the required working position or positions.
  • the aim of the invention is indeed to eliminate the previously described disadvantages by providing a grinder head particularly for chamfering-profiling machines for glass plate elements which can perform the translatory positioning of the grinder in a substantially automatic manner without requiring manual actuations and manual preset of the various stroke limit elements which were constituted by the tappets in the known art.
  • a particular object of the invention is to provide a grinding head which allows to preset, in a very rapid and simple manner, the various preselected adjustment positions, and furthermore allows to rapidly vary said positions.
  • Another object of the present invention is to provide a grinding head with control means which prevent incorrect actuations and in particular do not allow the axial movement of the grinder if the sleeve which supports the grinder has not been released.
  • Another object of the present invention is to provide a grinding head which by virtue of its peculiar implementation features is capable of giving the greatest assurances of reliability and safety in use.
  • Not least object of the present invention is to provide a grinding head which can be easily obtained starting from elements and materials commonly commercially available and is furthermore advantageous from a merely economical point of view.
  • the chamfering-­profiling machine for glass plate elements comprises essentially a base indicated at 1, of a per se known kind, which defines a star-shaped table 2 with suckers for locking the plate being machined; an arm 3 extends from said base and supports a grinding head, generally indicated by the reference numeral 4, which in a per se known manner has means which allow to vary its inclination about an axis which is substantially tangent to the edge of the plate being machined and means for inclining said head about an axis which is substantially perpendicular to the edge of the plate being machined, in particular a glass pane.
  • Said inclination adjustment means are of a known kind and are not described herein in detail, since they are not related to the present invention.
  • the grinding head 4 has a supporting frame, generally indicated by the reference numeral 10, which defines a cylindrical body 11 which extends towards the work area where the edge of the glass pane is located.
  • a sleeve 12 is accommodated inside the cylindrical body 11 and can slide axially therein; said sleeve internally rotatably supports the actuation shaft 13 of a grinder 14 which may be of any kind according to the machinings to be performed.
  • the shaft 13 is supported by the sleeve 12 through bearings, generally indicated at 15, and a labyrinth-like portion 15a also of a known kind which prevents the infiltration of dust.
  • the shaft 13 engages with a pulley 16 so that it can slide axially but rotates rigidly therewith; a belt 17 engages said pulley and draws its motion from a driving pulley 18 actuated by motor means constituted by the motor 19.
  • Means are provided for the axial translatory motion of the grinder towards and away from the work area; said means comprises a kinematic coupling including a gear 20 of the worm-screw type which is keyed on a control shaft 21 which extends parallel and to the side of the sleeve 12.
  • Said gear 20 couples with a rack-like portion 22 which is correspondingly defined on the sleeve 12, which has a longitudinal groove 12a engaged by a protruding tab 11a rigid with the cylindrical body 11 so that the sleeve 12 is prevented from rotating and the rotation of the gear 20 causes an axial translatory motion of the sleeve 12.
  • Motorized positioning means are provided on the shaft 21 and comprise a direct-current motor 30 with which an angular position control encoder 31 is associated.
  • the motor 30 is controlled by an electronic control and adjustment unit indicated at 40, which displays the position of the grinder and allows a plurality of preselectable work positions to be stored according to the various requirements.
  • Sleeve locking means act on the sleeve 12 and include, as is more clearly illustrated in figures 3 and 4, a pair of mutually opposite shaped jaws 41 and 42 which respectively have a shaped portion 41a and 42a which engages with the sleeve and an abutment portion 41b and 42b which abuts against the fixed structure.
  • One of said jaws, and in particular the first jaw 41, has a threaded hole 43 engaged by the threaded stem 44 of a rod 45 which passes through the other jaw 42 and has a widened head 46 which exerts the locking pushing action for the jaw 42.
  • the widened head 46 engages, by means of a key-like coupling or the like, with the tang 47 of a rotating piston 48 which has a cam 49 which interacts with the contact 50 of an enabling microswitch 51 which enables the operation of the motor 30 only after the locking means of the sleeve 12 have been released.
  • the rotating piston 48 may be actuated by an own motor means, also controlled through unit 40 so as to cause releasing of the locking means and the actuation of motor 30.
  • the user can store a series of preset positions which he can recall in each instance during machining, and he can modify them in any case according to his requirements.
  • the invention achieves the proposed aim and objects, and in particular the fact is stressed that the particular mechanical actuation adopted for the translatory motion of the sleeve 12 allows to automate the selection of the various positions, storing a plurality of positions which can be recalled in each instance during machining.
  • All the steps of axial translation of the grinder may furthermore be performed in an extremely rapid and automatic manner without requiring the operator's manual intervention, as instead occurs in the solutions of the known art which adopted tappets for the various positionings.
  • Another important aspect of the invention resides in that the use of locking means which control and prevent the operation of the motor 30 if the sleeve 12 has not been released, allows to always have great assurances of safety during the various work steps.
