Abstract
Abstract An apparatus for scoring a sheet of glass wherein the tool carriage moves along a fixed gantry located over the glass. The glass is moved into scoring position using initially a primary and then a secondary power means for the work moving conveyor.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
264 words
Device for scoring a sheet of glass to be cut up into volumes of a desired format, comprising a fixed gantry disposed transversely between an upstream conveyor and a downstream conveyor having endless belts which are driven by at least one drum operated by a driving device, a carriage which can move from one end to the other of the fixed gantry and is provided with a tool carrier adapted to lower the tool on to the sheet of glass with a view to scoring the latter during the translation movement of the carriage on the gantry and to raise the tool again when the latter has arrived at the end of its travel, a retractable stop capable of registering the front edge of the sheet of glass when the said edge has arrived at the scoring line, and of stopping the advance of the conveyors with a view to immobilizing the sheet of glass during the scoring operation, characterized in that it also comprises a means for unlocking the driving device for the conveyors and the drum or drums driving the belts, at the moment when the front edge of the sheet of glass arrives at the scoring line, and a means for positioning the sheet of glass, the said means acting upon the belts and causing them to advance, together with the sheet of glass which they are carrying, by a predetermined length in such a way that the sheet of glass is positioned, in relation to the tool, precisely at the place at which the subsequent scoring is to be effected.
Claim 2
Dependent Claim
264 words
Device for scoring a sheet of glass to be cut up into volumes of a desired format, comprising a fixed gantry disposed transversely between an upstream conveyor and a downstream conveyor having endless belts which are driven by at least one drum operated by a driving device, a carriage which can move from one end to the other of the fixed gantry and is provided with a tool carrier adapted to lower the tool on to the sheet of glass with a view to scoring the latter during the translation movement of the carriage on the gantry and to raise the tool again when the latter has arrived at the end of its travel, a retractable stop capable of registering the front edge of the sheet of glass when the said edge has arrived at the scoring line, and of stopping the advance of the conveyors with a view to immobilizing the sheet of glass during the scoring operation, characterized in that it also comprises a means for unlocking the driving device for the conveyors and the drum or drums driving the belts, at the moment when the front edge of the sheet of glass arrives at the scoring line, and a means for positioning the sheet of glass, the said means acting upon the belts and causing them to advance, together with the sheet of glass which they are carrying, by a predetermined length in such a way that the sheet of glass is positioned, in relation to the tool, precisely at the place at which the subsequent scoring is to be effected.
Claim 3
Dependent Claim
96 words
Device according to claim 1, characterized in that the means for unlocking the driving device for the conveyors and the drum or drums driving the belts, comprises a clutch which is itself controlled by the retractable stop for the purpose of disengaging the clutch when this stop is retracted after making contact with the front edge of the sheet of glass, in such a way that the belts are then disengaged from the conveyor drive and are coupled to the latter again when the rear edge of the sheet of glass has passed the scoring line.
Claim 4
Dependent Claim
35 words
Device according to claim 1, characterized in that the downstream conveyor is connected mechanically to the upstream conveyor in such a way that the belts of the two conveyors have the same speed of advance.
Claim 5
Dependent Claim
103 words
Device according to claim 1, characterized in that the means for positioning the sheet of glass comprises gripping members which are capable of bearing against the lower face of the bottom courses of the belts and are mounted on a transverse girder which can move parallel to itself in the direction of advance of the belts and is controlled by a device which is capable of displacing it by a distance corresponding to the length previously determined for the advance of the sheet of glass, either from its front edge which is located on the scoring line, or from the last scoring effected.
Claim 6
Dependent Claim
14 words
Device according to claim 4, characterized in that the gripping members are pneumatic cups.
Claim 7
Dependent Claim
118 words
Device according to claim 4, characterized in that the member capable of displacing the mobile girder is constituted by a set of jacks comprising a series of axially aligned jacks, in which series the piston rod of one jack is rigidly integral with the cylinder end of the following jack, these jacks being operated at full stroke and the stroke of one jack being normally different from that of the other jacks in such a way that, by choosing a specific combination of jacks to be actuated simultaneously, the effective travel of the set of jacks corresponds exactly to the desired displacement of the belts and thus to the length of advance sought for the sheet of glass.
