Fig. 3 is a block diagram of a breaking device of the glass-cutting apparatus o f Fig. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENTS GLASS CUTTING APPARATUS 10
Referring now to the drawings, and more particularly to Fig. 1, a glass-cutting apparatus in accordance with an embodiment is generally shown at 10. The apparatus 10 has a support table 11 and a breakage unit 12.
The support table 11 is provided to support glass panels such as glass panel A, while the glass panel A is submitted to a step of breaking. The breakage unit 12 emits a break wave for instance by producing an impact force that will cause the glass panel A to break at a score defined in the glass panel A. SUPPORT TABLE 11
The support table 11 typically holds the glass panel in a horizontal orientation, although other orientations are considered as well. In one embodiment, the glass panel A is clamped to the support table 11. The clamping is typically done by suction cups or like vacuum systems (e.g., holes in the planar surface of the table connected to a vacuum chamber) , or by mechanical clamps that hold the glass panel. In these cases, a temporary structural bond is established between the glass panel A and the support table 11, and this structural bond may be used subsequently to transmit a force or a break wave to the glass panel A. In another embodiment, the support table 11 is an air table (i.e., air conveying table) as commonly used to convey glass panels. Accordingly, with the use of an air conveyor, the glass panel A floats on the support table 11. In such a case, the break wave is transmitted in the form of a wave of appropriate frequency (e.g., a sound wave) . In an embodiment, the air table is used in combination with a vibrating breaking device (e.g., cams acting against the support table 11) . In this embodiment, the air between the table 11 and the glass panel A transmits the vibrations of the table 11 to the glass panel A so as to cause the breakage of the glass panel A at the score. It is also considered to have the floating glass panel A vibrate against the table 11. The support table 11 may be provided with conveying means, such as actuated rollers and the like, to displace the glass panels onto the table 11 and away therefrom. BREAKAGE UNIT 12
The breakage unit 12 is provided in association with the support table 11. The breakage unit 12 performs the score in the glass panel A, and emits a break wave of selected magnitude (e.g., frequency and amplitude) to break the glass panel A in a desired manner.
The breakage unit 12 has a breakage condition identifier 20 that determines a suitable impact force or frequency and amplitude for a break wave in view of the specifications of the glass panel A. The break wave will be produced by a breaking device 21 that is part of the breakage unit 12. Moreover, the breakage unit 12 optionally has the function of performing the score in the glass panel A, by way of a selection of scoring tools 22. The impact force/frequency and amplitude of the break wave, and the size of the score are selected as a function of the thickness of the glass panel A. The impact force/frequency and amplitude of the break wave and the size of the score (as a function of the scoring tool 22) must be selected to limit the breakage of the glass to the score in the glass panel A, while avoiding further breakage of the glass panel A.
The breaking device 21 may take various forms. In one embodiment illustrated in Fig. 3, the device 21 is a mechanical device that will transmit a force to the support table 11 in such a way that the force results in a break wave sustained by the glass panel A. More specifically, the device 21 has a pneumatic cylinder 21A whose output end will hit the support table 11. A control valve 21B controls the air pressure sent to the cylinder 2 IA so as to control the force of impact of the cylinder 21A against the support table 11. By way of example, the control valve 21B is a solenoid valve that is connected to and commanded by the breakage condition identifier 20. Alternatives to the pneumatic cylinder 2 IA are considered, such as hydraulic cylinders, an electrically-powered linear actuator, and any other mechanical means that will impact the table 11. In one embodiment, a hammering device is used in combination with resilient forces (e.g., springs, bungees) to impact the support table 11.
In another embodiment, the breaking device 21 produces a sound wave at the resonance frequency of the glass panel, to induce vibration in the glass panel. The sound intensity at the resonance frequency is selected so as to cause the breakage of the glass panel at the score. As an example, it is considered to increase the sound intensity at the resonance frequency until the glass panel breaks at the score. It is pointed out that the increase of the sound intensity is controlled to limit the breakage to the score.
In one embodiment, the identification of the panel data is entered by user/operator B, in the form of a thickness of the glass panel A, with optionally a scoring pattern to be effected by the breakage unit 12. The identifier 20 is a processing unit that converts the panel data to an emission command sent to the breaking device 21. The emission command will be in relation to the desired frequency (e.g., resonance frequency) and amplitude of the break wave, as determined by the breakage condition identifier 20; As an example, the breakage condition identifier 20 involves a database 2OA having wave/glass relation data, relating glass panel data to a suitable impact force, frequency (e.g., resonance frequency) and/or sound intensity increase pattern. Moreover, the wave/glass relation data of the database 2OA includes data relating to the score size required as a function of the thickness of the glass panel A. Therefore, the appropriate scoring tool 22 is selected through the breakage condition identifier 20. In another embodiment, the device 21 is an electromechanical or acoustic device that will emit a wave with the correct amplitude and frequency (e.g., resonance frequency) . This configuration is well suited for use with an air table.
Although not illustrated, it is considered to equip the breakage unit 12 with sensors that determine the thickness of the glass panel A. Such sensors provide panel data to the breakage condition identifier 20, which then commands the breaking device 21 and scoring tool 22, as described previously.
METHOD FOR CUTTING GLASS PANELS
Referring to Fig. 2, a method for cutting glass panels is generally illustrated at 30. In Step 31, a score is defined in the glass panel. The score represents a desired peripheral shape of the glass panel. The depth and angle of the score
(i.e., the score size) is a function of the thickness of the glass panel, amongst other factors, and the appropriate scoring tool 22 is specifically selected.
In Step 32, the scored glass panel is positioned on the support table 11. It is pointed out that the step 31 of scoring the glass panel may be performed on the support table, whereby the sequence of steps 31 and 32 may be inverted. According to the source of break wave, the glass panel may be clamped to the support table 11.
In Step 33, the impact force/frequency and amplitude of a break wave required to break the glass at the score is determined. The values of impact force/frequency and amplitude are calculated or obtained as a function of the thickness of the glass panel and the relation between the support table and the glass panel, amongst other factors. Alternatively, a calibration of the breakage unit 12 may be performed to gather the afore-mentioned data. In Step 34, the break wave is emitted at the selected force or frequency and amplitude (e.g., resonance frequency) , and the scored glass panel is exposed to the break wave, resulting in the breakage of the glass panel at the score.
In Step 35, the glass panel having the desired peripheral shape is obtained.
