Definitions

  • the invention relates to a combined cutting-fletting process using abrasive tools for glassware or crystalware and a device implementing the process.
  • Cutting with the aid of abrasive tools of glassware or crystalware generally aims to detach from the article itself the mass of glass or crystal, hereinafter called cap, which served to hold the article during its shaping phase by hot plastic deformation.
  • Flattering with glass tools or glassware using abrasive tools is the operation which follows that of cutting. It generally aims to complete the article edge generated by the cutting operation.
  • Cutting using glassware or crystalware articles using abrasive tools is conventionally carried out using an abrasive disc whose axis of rotation is situated in a substantially vertical plane.
  • the article being positioned so that the expected cutting plane merges with the plane of symmetry of the abrasive disc, the article is generally placed on its base on a substantially horizontal plane, the upper part of the mass of glass or crystal constituting the article to be cut constituting the part defined above as being the cap, the lower part of the mass of glass or crystal constituting the article to be cut constituting the article proper.
  • Cutting using glassware or crystalware articles using abrasive tools is also conventionally carried out using an abrasive disc whose axis of rotation is situated in a substantially horizontal plane.
  • the article being positioned so that the expected cutting plane merges with the plane of symmetry of the abrasive disc, the article is generally held by a device so that its base is located in a substantially vertical plane.
  • Cutting with the aid of abrasive tools of glassware or crystalware is also conventionally carried out using two abrasive discs working substantially at the same time and penetrating into the article to be cut following identical displacements.
  • the axis of rotation of the abrasive discs is generally located in a substantially vertical plane; the article is generally placed on its base on a plane substantially horizontal, the upper part of the mass of glass or crystal constituting the section to be cut constituting the part defined above as being the cap, the lower part of the mass of glass or crystal constituting the article to be cut constituting the article itself.
  • the sequence of operations is identical.
  • the disc (s) rotating at high speed slowly approach the stationary article and penetrate into this article of an adequate depth, i.e. if the article is full sufficiently close to the center or if the article is hollow enough for the rim of the abrasive disc to open into the central hollow; penetration is then considered complete.
  • the article is slowly rotated so that as this rotation occurs, the abrasive disc cuts a groove in the mass of glass or crystal which ultimately results in the detachment of the cap from the useful part of the article. Slow rotation of the article may already have started while the abrasive disc is still penetrating the article.
  • the trajectory of the disc during penetration into the article can be substantially radial, which corresponds for a given article to the most displacement weak abrasive disc; on the other hand, a single disc performing the cutting, the article will have to rotate about 360 ° to be completely cut.
  • the cap being cut is located above the cutting disc, which requires to be maintained manually or by a any device this cap in place during and especially towards the end of cutting.
  • the weight of the cap is applied to the section of glass or crystal still connecting the cap to the useful part of the article being cut, requesting this section following a bending force. This stress can cause the abrupt and premature detachment of the cap by fragile rupture of the glass or crystal section still connecting it to the useful part of the article.
  • This rupture can induce a significant chipping or more generally a mechanical deterioration of the edge or the bottom of the article generated by the cutting disc; the cap which has just detached from the useful part of the article may cause deterioration of the cutting discs and / or be thrown by them in an uncontrolled manner and dangerous for the operator.
  • the mixture constituted by the cutting liquid charged with glass or crystal dust trickles onto the useful part of the article.
  • the loaded cutting liquid accumulates in the hollow until possibly filling it completely and the article must either be emptied before 'remove from the machine, i.e. remove it from the machine filled with cutting fluid.
  • the shape of the article its surface must be thoroughly cleaned of glass dust which remains attached to it. This cleaning operation generally takes a long time; it is tedious to carry out manually; its automation is not simple considering the various forms of the articles.
  • the weight of the cap which is not maintained or inadequately maintained is applied during cutting on the glass section or crystal still connecting the cap to the useful part of the article, urging it according to a force composed of bending and shearing.
  • This stress can cause, as in the previous case, the brutal and premature detachment of the cap by fragile rupture of the section of glass or crystal still connecting it to the useful part of the article.
  • This rupture can induce, as in the previous case, a chipping significant or more generally mechanical deterioration of the edge or bottom of the article generated by the cutting disc; the cap which has just detached from the useful part of the article can also cause deterioration of the cutting discs.
  • the actual cutting can be carried out fairly quickly due to the presence of two discs working simultaneously.
  • the cap which has just detached from the useful part of the article rests on the two cutting discs; it can cause damage to the cutting discs and / or be thrown by them in an uncontrolled and dangerous way for the operator.
  • Edge or bottom flattering of glassware or crystalware items is conventionally carried out using an abrasive cup wheel whose axis of rotation is perpendicular or substantially perpendicular to the plane of the edge or bottom of the item generated by cutting.
  • the article being in slow rotation, the grinding wheel is applied on the bottom or on the edge of the article with a controlled effort; in the case where the grinding wheel has to machine a complete base, its abrasive rim will necessarily pass through the center of rotation of the article; in the case where a more or less thick wall of a hollow article is to be machined, the grinding wheel will be positioned so that its rim is sequent to this wall in two very distinct locations and if possible in two substantially opposite locations.
  • the machining of glass or crystal by the cup wheel continues at constant effort until the wheel sinking into the material, it comes to rest on a set mechanical stop to remove an optimal thickness of material.
  • the cutting and flailing operations are carried out on workstations or on different machines.
  • the article, loaded on its base, is substantially vertical, the part referred to above as the cap constituting the upper part of the mass of glass or crystal constituting the article to be cut; the axes of the cutting disc and of the grinding wheels are also substantially vertical.
  • the various operations taking place on successive stations, only the station on which the operation requiring the most time takes place is used permanently.
  • Document CH-A-446098 also discloses a machine for grinding glass edges, which comprises grinding discs, the only movement of which is rotary. These discs are flexible and slightly bent when they come into contact with the edge of the glass, when the latter is moved downwards.

  • This device is characterized in that two abrasive discs, mounted on the tool-holding units and whose axes are substantially vertical, carry out cutting by penetrating substantially simultaneously into the article in places and in substantially opposite directions of approach, in that cutting-off and flattering are carried out on the same work station by tools, cutting-off disc and flounder wheel, mounted on the same spindle, in that a mechanism mounted on the lower cross member on an axis parallel to the spindle and comprising the main motor and transmission elements allows the tool spindle to be placed in the high position or in the low position relative to the article, in that the adjustment of the position of the tool spindle in the position low, is achieved by a mechanism comprising first drive and transmission elements acting on the upper part of the drive and transmission elements main axis along the axis, and in that the adjustment of the distance traveled by the tool spindle passing from the low position to the high position is achieved by a mechanism comprising second motor and transmission elements acting along the axis by leaning on the lower crossbar.
  • the cap is located below the cutting disc and that its weight urges the two equivalent sections of glass or crystal still connecting during cutting the cap to the useful part of the article only in traction; it follows that this cap detaches in a balanced manner from the useful part of the article and falls by gravity without risk of damaging either the edge of the article generated by cutting or the abrasive disc. glass or crystal dust does not drip onto the article itself.
