Description

  This application for an invention patent is directed to the industry sector and involves flat glass cutting, with a horizontal cut made by high pressure, focused water, combined with an abrasive element to create holes and cutouts in the glass sheet. See the water jet cutting machine used in. Its unique feature when compared to water jet cutting machines that exist on the market is the possibility of operation in automated production lines with glass piece feeding, automatic face milling and referencing. This format meets the demands of the glass market with high productivity and production standardization.

  Using a fluid ultra-high pressure abrasive jet, abrasive particles are directed from a pressurized source onto the glass sheet. Currently, the market offers several machine configurations for sheet glass cutting and reaming, both for the machine on which the milling machine is mounted and for the water jet combined with the polishing element. Although they are very practical, such machines always rely on ancillary equipment for transporting the glass and place it below the cutting head for sheet glass cutting or reaming. And the cutting head always operates in three axes (X, Y and Z), while the plate remains stationary during cutting.

  In connection with the state of the art, document U.S. Pat. No. 4,703,591 describes a system for simple high-speed cutting in glass materials having different thicknesses. Due to the initial penetration into the glass, the pressurized source is maintained at a first level of pressure where the glass is initially cut without any excessive crushing or chipping and the polishing fluid flow is At one speed, it can be advanced against the glass through the entire desired path.

  Although it performs its work according to its specifications, the ultra-high pressure water jet does not have any automated means of grabbing the sheet glass and placing it under the cutting head, which is used to place the glass on a cutting table. Requires the assistance of at least four people. Piece embodiments can be scratched due to scratches resulting from this process. Another gap in the installation is for the cutting head, which operates in three axes (X, Y and Z). This can lead to inaccuracies if the head is not fully calibrated, or if the particles move involuntarily during operation.

  The present patent introduces a new technology that allows cutting or reaming glass pieces in a more accurate, automated and safe manner without damage to the glass pieces, especially scratches caused by other techniques. It is intended to be presented to This goal came from the lack of automated water jets with abrasives and the gaps detected in the current state of the art.

  The description that follows, based on its principles, aims to emphasize the proposal without any limitation on the figures or component models, and makes reference to the accompanying images.

  According to FIGS. 1 and 2, a waterjet cutting machine (1) for cutting sheet glass comprises an input conveyor belt (2.1) arranged along its longitudinal path and moved along an axis X; A loading table (2) with a face milling ruler (2.3) having a sensor (2.2) (Details B) and its sensors (2.4) (Details C), and data (supervisory) A computerized system (3) for storing the chip measurement results, its notch and position) and a focusing nozzle (4. moving horizontally along the axis Y and vertically along the axis Z). 1) a cutting head (4) (details A and D), and finally a discharge table (5) on which a discharge conveyor belt (5.1), which is arranged lengthwise in the installation, is mounted. You.

  The waterjet cutting machine (1) for cutting sheet glass starts at the input table (2), which receives the sheet glass from the previous process using the input conveyor belt (2.1) and moves it to move the cutting ruler (2). .3) The work is completed by the automatic end-face shaving of the small piece and the removal using the photoelectric sensor (2.2). In this first step, the operator checks the barcode of the small pieces generated from the design developed by the dedicated CAD software. The machine stores the small piece measurement result, the notch and the position thereof in the monitoring device. Furthermore, for the input conveyor belt (2.1), the pieces to be punched or edged are moved to the loading area of the machine, where the second sensor (2.4) performs the belt removal. The small piece is moved to an axis reference mechanism which is in charge of finding the point where the small piece is generated. The machine now starts the cutting process and moves the pieces on the input conveyor belt (2.1) along the axis X, while the main cutting head (4) moves as defined by the CAD software scheme, Performing a cutting movement along axis Y by interpolating the movement in an efficient and coordinated manner via PLC and combining their axes, and focusing nozzle (4.1) along axis Z Approach or pull back.

  The cutting takes place due to the high pressure of the pump intensifier system in an external unit integrated with the machine, which sends a water jet with an abrasive element for cutting the glass sheet to a focusing element. After the machine has made all defined design cuts, the pieces are moved by the input conveyor belt (2.1) to the output conveyor belt (5.1), which is connected to other machines in the sheet glass process. Belonging to the discharge table (5) that can be performed.

  The purpose of the water jet cutting machine for sheet glass cutting is positioning tools and machining, which are configured especially for the functions of cutting head (4), input conveyor belt (2.1) and output conveyor belt (5.1). (Hole and / or cutting) functional movement, in particular on or in sheet glass with several lengths, widths and thicknesses, by means of positioning and synchronized functional movement during drilling or cutting of a particular piece. Inside is to make a cutout by drilling holes in an automatic way.

  Sheet glass cutting water jet cutting machines perform horizontal cutting with high pressure water combined with a polishing element to create holes and cutouts in the sheet glass. Its unique feature when compared to the water jet cutting machines that exist on the market is the possibility of operation on automated production lines with glass slab feeding, automatic face milling and referencing, implementing high productivity and production standardization. is there.
