1. A discrete grooving system (10) that allows channel grooving on the glass, which reduces production costs by reducing the number of disks and allows channel grooving at desired length and depth in the desired area of the glass, characterized by comprising: a DOP screen (11) which enables the grooving on the glass via a PLC software and where the channel dimensions are entered, an encoder (12) which determines the speed and calculates the path taken by the glass per unit time to measure the channel, a channel engine (15) that allows the discrete channel to be opened by moving upward and downward on the glass, a pneumatic valve (14) that allows a channel engine (15) to be moved upward and downward, wherein the channels are opened on the glass in desired dimensions by operating the channel engine (15), by means of the encoder (12) which takes the machine speed information, make the channel measurement and consequently open the desired channel via the upward and downward movement of the channel engine (15) actuated by the pneumatic valve (14), a switch (13) which allows the incoming glass to be detected by the channel engine (15), a PLC software that manages the activation of the pneumatic valve (14) with the data of the switch (13) and encoder (12), and the process of opening the channels in the desired size and length by moving the channel engine (15) upward and downward.

Description

Technical Field The invention relates to a discrete channel grooving system developed to open a channel in the required dimensions in the glass industry. The invention particularly relates to the discrete channel grooving system, which reduces costs by using fewer discs and allows channel engraving at the desired length and depth in the desired area of the glass. Prior Art The glass is a basic material of use that humanity cannot give up and pass. Since ancient times, glass has been used both in constructions and ornaments. In present, it still has a wide area of use from the simplest tools to communication and space technologies. After formatting, the glass produced may not have the qualities to be used. Therefore, with the use of methods such as cutting, tempering, grinding, grooving, bevelling, acid, sandblasting etc. and the applied processes, the glass is made suitable for the area to be used. The image obtained by engraving on the glass surfaces is called grooving. In the areas of interior decoration and furniture, flat and shaped channel applications can be made on the surfaces of glass and mirror. By giving an aesthetic appearance from the edges of the glass in channel applications, glass mirrors are provided with functionality. In the areas of interior decoration and furniture, flat and shaped channel applications can be made on the surfaces of glass and mirror. The shaping of the surface of the glass is engraved at different depths along a straight line and is called flat grooving. Channel blocks (discs) are fixed in the flat grooving process. The engraving process is carried out by moving the glass along a straight line through the fixed channel blocks. Shaped channel grooving is done in CNC machines. In this type of grooving, the glass to be processed is fixed while the channel blocks are in free motion. This process is performed on the surface near the edges of the glass. Channel grooving materials are channel blocks (disc) and seals. To groove a channel, the depth and width of the channel are important. While the depth and width of the channel are created by the channel blocks, the seals perform the polishing process. The channel block makes the engraving on the glass. The depth and width of the channel on the glass is formed by the channel blocks. Far the width and depth of the channel that can be opened at a time, only one piece of channel block and one seal is enough. The wider or deeper channels are made via using two channel blocks. One of these blocks should be rough and the other should be thin. The rough block gives the depth and the thin block gives form. Today, two types of machines are used in the channel grooving operations as flat channel machines and CNC machines. In flat channel machines, the surface of the glass is carved in various depths and widths along a straight line to give the shape. Flat printing machines include one plotter stone, two diamond stone (channel block) and two seals. In the CNC machines, grooving in desired patterns is performed on the surface of the glass. The desired shape can be processed automatically in CNC machines on glass surfaces of various thickness and types through the computer programs. CN106670654A discloses a glass surface grinder that replaces traditional mechanical engraving heads with a laser emitting head, enabling high-precision engraving on glass surfaces without frequent tool replacement. The device comprises a table, three stepper motors, and two conveyor systems arranged perpendicularly to each other to move the laser beam longitudinally and laterally via drive wheels, belts, and rollers on guide rails. A beam structure supports the laser generator, fiber-optic cable, and laser head, allowing full-plane movement of the laser for engraving operations. CN205498449U discloses a numerical control (NC) glass groove machine system that integrates traditional sandblasting-type glass engraving with modern computer-based CNC technology. The system combines a PC with a DMC1000 multi-axis motion control card to create an open-architecture digital control platform for glass engraving. The structure includes a bearing base, Y-direction motor, Z-axis mounting rod, Z-direction slide, pneumatic control valve, X-direction motion bracket, X- and Y-axis motors, and a pneumatic engraving nozzle. The motors are controlled through the DMC1000 motion control card, while pneumatic operations are managed via a digital I/O card. PLC software and screen-operated flat channel grooving machines in use today enable opening of the uninterrupted and continuous flat channels along the edges of the glass. In the said method, the motor opening the channel at the desired depth along the glass has a negative effect on spindle and engine life. On the other hand, the necessity of single and continuous operation of the channel in the current method causes the demand of theconsumer to not be met. As a result, the need tor a discrete channel grooving system that resolves the
