Its unique characteristic when compared to the water jet cutting machines existing in the market is the possibility of operating in an automated production line, with glass pieces feed, automatic shoulder milling and referencing. This format meets the demands of the glass market with high productivity and production standardization. The purpose of the water jet cutting machine for plate glass cutting is to drill holes and make cutouts in an automatic way, on or in plate glass with several lengths, widths and thicknesses, specially by means of positioning tools and machining (hole and/or cuts) functional movements, configured for the functionalities of the cutting head (4), input conveyor belts (2.1) and output conveyor belts (5.1), specially by the positioning and synchronized functional movements during the drilling or cutting of a specific piece.

Description

  • This request for an invention patent is oriented to the industrial sector and refers to a water jet cutting machine used in plate glass cutting, with the horizontal cut being made with high pressure focused water combined with abrasive elements in order to make holes and cutouts on plate glass. Its unique characteristic when compared to the water jet cutting machines existing in the market is the possibility of operating in an automated production line, with glass pieces feed, automatic shoulder milling and referencing. This format meets the demands of the glass market with high productivity and production standardization.
  • By means of a fluid ultra-high pressure abrasive jet. Abrasive particles are aspired and directed from a pressurized source against the plate glass. Currently, the market offers several configuration of machines for plate glass cutting and reaming, both for machines equipped with milling cutter and for water jet combined with abrasive elements. Although they are pretty practical, such machines always depend on ancillary equipment to convey the glass and place it under the cutting head for the plate glass cutting or reaming. And the cutting head always operates in three axis (X, Y and Z) while the plate remains static during cutting.
  • In relation to the state of the art, document US4703591 describes a system for simple highspeed cuttings in raw glass with different thicknesses. For the initial penetration into the glass, the pressurized source is kept in the first level of pressure in which the grass is initially cut through without any unduly fractures or chips in the cutting point and the abrasive fluid flow can be advanced throughout the desired path in relation to the glass at a first speed.
  • Although it performs the task according to its specifications, the ultra-high pressure water jet does not have any automated means to grab and place the plate glass under the cutting head; it demands the aid of, at least, four people to place the glass on the cutting table. The aspect of the piece may be compromised due to scratches resulting from this process. Another gap of the equipment is about the cutting head, which operates in three axis (X, Y and Z). It may lead to imprecision if the head is not perfect calibrated or if the piece involuntarily moves during the process.
  • This invention patent aims at offering the market a new technology capable of cutting or reaming glass pieces in a more precise, automated and safe way, with no damage to the pieces, specially scratches caused by other techniques. This objective came from the lack of automated water jets with abrasives and from the gaps detected in the current state of art.
  • The description that follows below aims at highlighting the proposal, based on its principle, without any limitations to the diagram or component models, and referring to the following images:
    • Figure 1, schematic drawing representing the water jet cutting machine for plate glass cutting (front view);
    • Figure 2, view in perspective of the machine, detailing its main mechanic and electronic components;
  • According to figures 1 and 2, the water jet cutting machine for plate glass cutting (1) is composed of an input table (2) with input conveyor belts (2.1) placed along its longitudinal path and moved along axle X, photoelectric sensors (2.2) (detail B) and shoulder milling rule (2.3) with its sensor (2.4) (detail C); computerized system (3) for data storage in the supervisory: pieces measures, its cutouts and positions; cutting head (4) (detail A and D) with focusing nozzle (4.1) horizontally moving along axle Y and vertically moving along axle Z, and, finally, an output table (5) equipped with output conveyor belts (5.1) placed lengthwise in the equipment.
  • The operation of the water jet cutting machine for plate glass cutting (1) starts in the input table (2) which, by means of the input conveyor belts (2.1), receives the plate glass from previous processing, moves it and ends the task with the automatic shoulder milling of the piece on the milling rule (2.3) and the removal by means of photoelectric sensors (2.2). In this initial stage, the operator checks the piece bar code generated from the design developed with a dedicated CAD software. The machine stores piece measures, its cutouts and positions in the supervisory. Still, in respect to the input conveyor belts (2.1), the piece to be drilled or shoulder milled is moved to the machine loading area, where the second sensor (2.4) makes the belts retrieve and move the piece to the axle referencing mechanism responsible for finding the piece's origin point. The machine now starts the cutting process, moving the piece on the input conveyor belts (2.1) along axle X, while the main cutting head (4) performs the cutting movements along axle Y, bringing close or pulling back the focusing nozzle (4.1) along axle Z, with a combination of these axis and the interpolation of movements in an efficient and coordinated way, via PLC, as predefined by the CAD software scheme.
  • The cut is made due to the high pressure of a pumping intensifier system in an external unit integrated to the machine, which sends to the focusing nozzle a water jet with abrasive elements that cuts the plate glass. After the machine cuts all defined designs, the piece is moved by the input conveyor belts (2.1) to the output conveyor belts (5.1), which belong to the output table (5) that can be connected to other machine in the processing of the plate glass.
  • The purpose of the water jet cutting machine for plate glass cutting is to drill holes and make cutouts in an automatic way, on or in plate glass with several lengths, widths and thicknesses, specially by means of positioning tools and machining functional movements (hole and/or cuts), configured for the functionalities of the cutting head (4), input conveyor belts (2.1) and output conveyor belts (5.1), specially by the positioning and synchronized functional movements during the drilling or cutting of a specific piece.
  • The water jet cutting machine for plate glass cutting performs the horizontal with high pressure water combined with abrasive elements in order to make holes and cutouts on plate glass. Its unique characteristic when compared to the water jet cutting machines existing in the market is the possibility of operating in an automated production line, with glass pieces feed, automatic shoulder milling and referencing, which demonstrates high productivity and production standardization.
