Definitions

  • the present invention relates to the control of a machine for working the edges of a sheet of glass carried by a rotating support plate, a machine whose working tool is movable in the direction of the axis of rotation of the support plate and is subject to remain in contact with the edges of the glass sheet to be worked.
  • a machine of this type for grinding the edges of glass sheets is described for example in document DE-OS 1 928 162.
  • the grinding tool is guided by a roller which is associated with it and which s 'presses a template having a shape corresponding to the shape of the glass sheet to be ground, said template being placed parallel to the glass sheet and rotating at the same time as it.
  • the object of the invention is to provide a machine for processing the edges of glass sheets, in particular a grinding machine which does not have these constraints, in particular a machine which does not require a template or a new control program when the glass model to work changes.
  • the machine to position the working tool relative to the glass sheet, unlike the known art, no template, no preset program specific to each glass sheet is necessary.
  • the machine itself explores the outline of the glass sheet and establishes itself, after its exploration, a program for controlling the working tool.
  • the path or location information is supplied to a memory only for a portion of the periphery of the glass sheet and extracted from the memory when necessary.
  • the information is collected by a movable feeler in the direction of the axis of rotation of the glass support plate which is located in front of the working tool, that is to say which explores the areas to be worked before the work tool, and offset by a given angle ( ⁇ , ⁇ ) (alpba, beta) relative to it.
  • the signals corresponding to the position values of the points of the edge of the glass sheet are entered into a shift register and after crossing the register after a tenps corresponding to the tenps that the support plate puts to turn the angle ( ⁇ , ⁇ ) (alpha, beta) which separates the contact points on the edge of the glass from the feeler member and the working tool, are used to control a motor which positions the working tool.
  • the memory temporarily always only contains the path information corresponding to the path section located between the feeler member and the working tool.
  • the invention makes it possible not only to grind successively and in any order of the glass sheets of any shape, but also to remove all the constraining apertures of precise positioning of the glass sheets. This considerably increases the possibilities of using the grinding machine and eliminates the stops which for the previous machines were necessary at each change of program or template.
  • the invention is mainly used mainly for the control of a grinding machine acting on the edges of a glass sheet, but it can also be applied to the control of another machine acting on the edges of any object or even on the surface of said object object, the areas of the surface being identified with respect to the edges.
  • certain glazing units have the periphery of their surface covered with an electrically conductive strip, or with a decorative strip, machines controlled according to the method of the invention may advantageously be used for depositing such strips.
  • the working tool in particular a grinding member, and a feeler member can be mounted offset by an angle ⁇ (alpha) relative to each other, each on a carriage can be moved linearly radially with respect to the axis of rotation of the glass support plate, and the carriage carrying the feeler member can be provided with a path indicator delivering an electrical signal representative of the path identified, said signal having entered the shift register of a memory, then after a delay corresponding to the time of rotation of the angle ⁇ (alpha) by the support plate, directed on an amplifier then on the regulation system of the drive mechanism of the carriage carrying the working tool.
  • the working tool is carried by an oscillating arm and moves on a circular path
  • the feeler member is carried by a swing arm scond offset by an angle ⁇ (beta)
  • the information of path noted by the feeler member are entered into a memory from which they are extracted after a certain time lag to control the positioning motor of the arm carrying the working tool.
  • a constant torque motor acting by means of a shaft on the carriage carrying the feeler member ensures constant pressure of the feeler member in the event that it can be moved linearly, this engine also being loaded to advance the feeler roller from a rest position in the working position and from the working position to the rest position.
  • a constant torque dicer is also mounted on the pivot axis of the swinging arm and ensures constant pressure of the feeler member as well as the advancement of this feeler member towards the sheet of glass to be worked.
  • the working tool is also advantageous for the working tool to be pressed against the edge of the glass sheet by means of a constant torque motor with a constant or adjustable force.
  • the pressure can be changed during a grinding operation using this constant torque motor, for example when passing around sharp corners.
  • a tachometer generator is connected to the shaft of the tool positioning motor, and the signals it emits at the same time as the signals from the path indicator which determine the position of the tool, are transmitted to an operating unit whose output signal is used to regulate the speed of the drive motor in rotation of the support plate.
  • the invention is illustrated in the form of a machine for grinding the edges of glass sheets, although it can also be applied to other machines.
  • the glass sheet 1 to be ground is mounted on a rotating support plate 2, for example with a suction cup. This is moved slowly in rotation by a drive motor 3 during grinding.
  • the grinding tool 6 is mounted on a carriage 7.
  • the carriage 7 moves radially relative to the axis of the turntable 2 on rails 8 not shown in Figure 1.
  • a feeler roller 11 also mounted on a carriage 12 can be moved radially relative to the axis of the turntable 2 is offset by an angle ⁇ (alpha) relative to the direction of movement of the grinding tool 6 in the opposite direction to that of the rotation of the turntable 2.

  • the engine 16 is a constant torque motor which maintains a constant pressure of the feeler roller 11 against the glass sheet. By the action of this motor 16, the carriage 12 can also be moved away from the plate 2 during the rest periods.
  • a tachometer generator 13 is coupled to the screw 14 or to the motor 16 for controlling the speed of change of position of the feeler roller 11.
  • the signals from the tachometer generator 13 are used to regulate the pressure of the grinding tool 6 on the glass and are therefore supplied to the measurement triggering device 95.
  • the feeler roller 11 is rotated by a motor 15.
  • the position of the carriage 12 carrying the feeler roller 11 is indicated by the path indicator 18.
  • the path indicator 18 has the form of a sliding contact forming a cursor which moves along a resistor 19 and which takes an electric voltage corresponding to the position of the sensor roller. This voltage is brought via line 20 to the analog-digital converter 21 in which a corresponding digital value is formed which is then entered in memory in the shift register 22.

  • the positioning of the grinding tool 6 is ensured by a motor 28 fixed to the frame of the machine, which acts by means of the screw 29 on the carriage 7 carrying the grinding tool 6.
  • This motor 28 is put in action by the regulating amplifier 31 via line 30.
  • the carriage 7 carrying the grinding tool 6 is also provided with a path indicator 34 which has the form of a sliding contact forming a cursor which moves along the resistor 35.

  • the path indicator 34 has yet another function. It in fact governs, in conjunction with a tachometer generator 38 coupled to the motor shaft 28, the rotation speed of the motor 3 driving the turntable 2. The purpose of this adjustment of the speed of rotation of the turntable is to maintain constant the effective grinding speed. When changing the position of the grinding tool 6, the movement of the grinding head is superimposed on the rotational movement of the glass sheet 1, which leads to an undesirable increase or decrease in the effect grinding.
  • the grinding pressure exerted by the grinding tool 6 on the edge of the glass sheet is measured in the form of the two pressure components using two dynamometric capsules 47 and 48.
  • the grinding 6, including the grinding wheel drive motor is mounted on a mounting plate 49 which, for its part, is mechanically connected to the carriage 7 by means of the torque capsules 47 and 48.
  • the force component measured by the dynamometric capsule 47 depends on the position of the edge of the glass sheet and can take both a positive and a negative value since this position of the edge of the glass sheet relative to the grinding wheel can vary continuously.
