    PROCEDURE AND DEVICE FOR THE TREATMENT OF FLAT GLASS UNITS IN A GLASS PROCESSING INSTALLATION
    The invention relates to a method and a device for the treatment of flat glass units in a glass processing facility. Particularly the invention relates to a method and a device, which are used in an installation for cutting flat coated glass of any type, such as flat glass or safety glass sheets.
    Glass processing facilities, which, for example, feature flat glass processing machines for cutting flat glass for the construction industry generally produce individual glass units, which are further processed later for windows, doors, facades , or other purposes. Often these individual glass units, for different reasons, for example for protection against solar radiation are provided with a coating. If such a glass unit is further processed, this coating must be removed in the marginal area of the respective glass unit, and specifically in a process arranged upstream of the cut. This usually happens with the help of a pickling device, as known for example by the document EP 517176 A1. The abrasive tool is used as pickling tool, for example. Accordingly, a process for the treatment of flat glass units in a glass processing installation is known in which the flat glass units have at least one glass surface provided with a coating, in which the coating in pickling areas which can be determined previously is removed by means of a pickling device, so that at least one pickling contour is configured along a boundary between coated and pickled glass surface.
    If the pickling zone (strip) is on the edge of an individual glass unit, then only a pickling contour is presented. In general, however, there are two stripping contours facing each other, because the elimination of the coating preferably takes place in the glass blank before it is cut into individual sheets. In this case, along the division contour provided for the subsequent cutting operation on both sides of the cutting lines that are to be generated the coating must be removed. By pickling arranged upstream of the cut is guaranteed, between

    other things, also the adhesion of adhesives that may be necessary for fabrication. In both cases it is necessary to check the quality of the contour or the stripping contours. Also, depending on an additional treatment of the flat glass units, it may be convenient to detect in an exact, qualitative and / or quantitative way the existing pickling contours to check and evaluate for example the quality of the identification contours. If necessary, defective contours can be treated later. The pickling contour detection can be useful in relation to many types of treatment of flat glass units, such as for placement operations, cutting and / or separation operations.
    Thus, for example, it should be considered that for a cutting process the glass or partial or transverse gross pieces to be cut are usually placed by means of mobile clamps, clamping suction cups, stop taps or the like as it is going to cut. In this regard, the actual position of the aforementioned devices is usually detected by an electronic measurement system, also called a transducer, in the same device or installation. For this reason, however, it is only attempted to achieve a sheet measurement as accurate as possible, which also ultimately leads to the assumption that the cut is made in the center of the pickling contours. In practice, however, it is demonstrated that, by mechanical tolerances, wear, or the like, only compliance with the given tolerances (normally <1mm) between the cutting edge and the pickled contour or contours can be guaranteed with difficulty.
    The objective of the present invention is to improve a process for the treatment of flat glass units so that the aforementioned drawbacks of the state of the art are overcome and an efficient operating device can be realized for carrying out the procedure in a processing installation of glass. The present invention will be suitable in particular to detect qualitatively and / or quantitatively exact stripping contours to test and evaluate, for example, the quality of detection contours. Furthermore, in relation to cutting processes, the optimal placement of previously stripped units will be made possible by direct identification of the pickling contour (s) so that the cut to be made runs as accurately as possible in the center between two stripping contours facing each other.
    The objective is solved by a procedure with the characteristics of the

    claim 1.
    Therefore, a procedure is proposed for the treatment of flat glass units in a glass processing installation in which, by means of a sensor system, the at least one pickling contour is detected. For this purpose, preferably as a sensor system, an optical sensor means is used, in particular a contrast, reflection and / or image sensor, the particular sensor means being able to be configured as a camera.
    The invention also facilitates a glass processing installation, which applies the procedure for the treatment of flat glass units, presenting the installation, or a device installed therein, a sensor system according to the invention, which detects the minus a pickling contour. Preferably this happens in a process arranged upstream of the cut, that is, for a preparation for the cutting of the flat glass units. The installation according to the invention can be used for any type of flat coated glass, eg for a flat glass coated on one or two sides, safety glass and the like. Particularly the invention is suitable for the preparation and control of an optimal cutting operation in the pickled areas respectively of the (partial) blank.
    Additional advantageous configurations of the invention also result from the dependent claims.
    Therefore, the procedure is used for the placement of flat glass units for a cut made in the installation of flat glass units, the position and / or the course of at least one pickling contour being detected by the sensor system , to control, depending on the above, the placement of flat glass units during cutting. In this context the coating is removed in the pickling areas so that they extend respectively along a cutting line that can be determined previously, controlling the cutting of the flat glass units so that the cutting line, in particular in the center, runs between two stripping contours facing each other respectively.
    The sensor system can be mounted, for example, on a part of the installation located above the flat glass units, in particular on a carriage of a cutting tool. The sensor system can also be used "only" for an examination of

    automated quality of pickling areas that can be determined previously from flat glass units. Alternatively or in addition to the optical sensor means, the sensor system may also have capacitive and / or resistive sensor means. It can also be advantageous when, in order to detect the pickling contour, the flat glass units are illuminated and / or examined in the light by means of a lighting device.
    The method according to the invention serves in particular to detect flat glass units in a glass processing installation and uses at least one sensor system to accurately detect the at least one pickling contour, using as a sensor system a optical sensor means, in particular a contrast, reflection and / or image sensor, and / or the particular sensor means being configured as a camera or as a laser with a detector unit.
    Additionally, the process may be designed so that the coating in the pickling zone is removed by means of a pickling device to configure the at least one pickling contour. Therefore, the method can be used to detect by means of the sensor system the at least one pickling contour for a preparation of an additional process step, in particular for an additional process step, comprising a placement operation, a test operation cutting and / or separation operation.
    The procedure can be used for the placement of a tool and / or flat glass units for a treatment carried out of the flat glass units in the installation by means of a glass treatment device, detected by the sensor system the position and / or the course of the at least one pickling contour, to control, depending on the above, the placement of the flat glass units and / or the tool before or during the treatment, and / or for monitor the result later, in particular when the treatment comprises a cutting or separation process.
    For the preparation of the treatment of the flat glass units the coating in the pickling areas can be removed so that they extend respectively along a treatment line that can be determined previously, in particular the cutting line, by controlling the treatment of flat glass units using the sensor system so that the treatment line runs a defined distance

    with respect to the stripping contour, in particular in the center, between two stripping contours facing each other respectively or at a defined distance from at least one stripping contour.
    The sensor system can be mounted in a part of the installation located totally or partially above and / or below the flat glass units, in particular on a machine body or in a glass treatment device, in particular on a car of a treatment tool. Also, the sensor system for identifying at least one pickling contour can be mounted independently and not connected to a machine body. By means of the sensor system the at least one pickling contour can be detected reliably for a quality examination of the pickling areas that can be determined previously from the flat glass units. Also by the sensor system the quality of the pickling can be detected qualitatively and / or quantitatively in the pickling zone of the flat glass unit. As a sensor system, eg capacitive, resistive and / or inductive sensor means can be used.
    In addition to detecting and / or measuring the at least one pickling contour, the flat glass units can be illuminated and / or examined in the backlight by means of at least one lighting device.
    The sensor system can also be used to represent or further process information on the pickling zone and / or the pickling contour, the additional processing being carried out in particular automatically, partially automatically or manually and presenting a controller or regulator character.
    The invention also relates to a glass processing installation for the treatment of flat glass units, which have at least one glass surface provided with a coating, in which at least one pickling zone with at least one contour is configured. of pickling, presenting the installation itself, or a device installed directly on it or away from it, a sensor system, which detects the at least one pickling contour. Preferably the sensor system may have an optical sensor means, in particular a contrast, reflection and / or image sensor, the particular sensor means being configured as a camera or as a laser with a detector unit.

    Particularly the installation can have a control (eg a PC) and means to treat the flat glass units, the sensor system detecting the at least one pickling contour for the placement of the flat glass units or the tool of treatment before or after treatment, and detecting the sensor system the position and / or the course of at least one pickling contour. The control, depending on the above, can control and / or regulate the placement of the flat glass units, or indicate the placement of the treatment tool during the treatment of the flat glass units.
    The pickling device before the treatment can remove the coating in the pickling areas so that they extend respectively along a treatment line that can be determined previously, the control controlling the treatment of the flat glass units then so that the treatment line runs at a defined distance from the pickling contour, in particular in the center, between two pickling contours facing each other or at a defined distance from at least one pickling contour. In this case the sensor system may be mounted in a part of the installation located totally or partially above and / or below the flat glass units, in particular on a machine body or in a glass treatment device, in particular on a car of a treatment tool.
    In addition, a device is proposed that is created for said glass processing installation for the treatment of flat glass units, which have at least one glass surface provided with a coating, which has at least one pickling area, so that this it has at least one pickling contour along a boundary between coated and pickled glass surface, the device being installed at or very close to the installation and presenting a sensor system that detects the at least one pickling contour.
    The device can perform a computer-assisted detection of the at least one pickling contour or a quantitative and / or qualitative detection of the pickling zone with the aid of a data processing means, in particular with the help of a control installed for installation , which depending on the detection of the at least one pickling contour represents and / or controls and / or regulates a placement of the flat glass units or the treatment tool during the treatment in the installation and / or supports an assessment on the pickling area quality.

    The invention and the advantages resulting from it are described in detail below by means of realization examples and referring to the accompanying drawings that show the following:
    Fig. 1 schematically represents the structure of an installation for treatment, in particular for cutting flat coated glass, in which the procedure for detecting pickling contours is carried out, to optimally place the glass sheets they are going to cut themselves;
    Fig. 2 illustrates the detection carried out by means of an optical sensor system with two facing strips facing each other and a dependent placement thereof for the cutting of the glass sheets; Y
    Fig. 3 shows a schematic flow chart for the method according to the invention.
    Fig. 1 shows the structure of a glass processing facility 100, which is created to carry out the process according to the invention. Installation 100 has, among others, an area where the raw part or raw sheet is fed without cutting 200 of the installation (see arrow). For the blank, the clipping plane 210 is shown as an example for the flat glass units intended to be manufactured of which, by way of example, three units are provided with reference numbers 201, 202 and 203. Installation 100 It comprises, among others, a pickling device 110 and cutting device or cutting bridge 120 arranged in continuation in the process that can consecutively carry out the necessary cuts according to the cutting plan. Whenever after a cut there are still pieces together, that is to say sheets not yet completely separated, they speak of traverses. Said traverse is represented in Fig. 1 and is provided with the reference sign T.
    In Fig. 1 the situation in which a first cut (X cut) has already been made and in which the traverse T is now located for the second cut (cut Y) turned 90 degrees below is shown by way of example of the cutting bridge 120. From the traverse T the individual sheets will then be cut later, in this case initially the sheet 201. For the preparation of the cut in the installation, that is to say before the glass material is cut by below the cutting bridge 120, the blank glass 200 intended to be cut or the respective traverse is processed with the aid of pickling device 120, to remove from the glass along the predetermined cutting lines 211 in the cutting plane 210 the coating B by zones.

    In Fig. 3 the development of the method 10 is schematically represented, step 11 referring to pickling by areas of the glass blank or the partial blank, step 12 to the identification or detection of pickling contours, and step 13 to a controlled cut according to the above and the separation to give rise to the desired glass units.
    With reference to Figure 2, it is clarified that a strip stripping zone D is configured for straight cuts, this can be done, for example, by mechanical removal of the coating B from the glass surface. For this purpose, for example, a grinding machine (in the pickling device 110) that rectifies a strip of approximately 20 mm in width can be used. Therefore, in contour edges, stripping contours K and K en are configured respectively, which in this case are detected with the aid of an optical S sensor system. For example, in this case it is a camera, which is connected to a PC data processing unit and detects at least a partial area of the strip D. The sensor system S and the PC data processing unit form a device according to the invention 150, which can be installed in the installation or integrated into it. The data processing unit is preferably implemented by the existing computer for the control of the installation 100 (personal computer). This PC computer also controls in particular the placement of the glass material intended to be cut during the entire process.
    In order to identify or detect the stripping contours K and K 'shown by way of example in Fig. 2, at least one image is taken by means of the sensor system S and the image data is subjected on the PC computer for example to a contrast and / or reflection analysis. In the example shown as a sensor, a camera is used which, with the help of the PC computer, identifies the boundaries between the coated surfaces and the pickling area D to detect therefore position and course of the respective pickling contours K or K ‘. When it is going to be a straight line course, that is, straight cuts are going to be made in many cases it is enough to carry out the detection for example at a point, as shown in Fig. 2. As soon as with help the positions of the two stripping contours K or K 'have been detected from the camera S and the PC computer, the position of the desired cutting line M can be determined. In many cases, the central line is determined, but it can also be desired in terms of the process technique that the cutting line runs somewhat more displaced, that is, a certain lag is planned. If necessary, it may also be sufficient to detect only one of the two stripping contours K and, depending on the above, determine the position or course of the
    5
    10
    fifteen

    25
    30
    35
    cutting line. By means of the exact determination of the position of the contour or the stripping contours, the glass unit intended to be cut, in this case the traverse T, can be placed in a new position, or repositioned with the help of the devices described above, so that The cutting line is optimally positioned between both pickling contours.
    In the embodiment of the invention described in this case, a camera S is installed on the carriage of the cutting tool, which can move in the direction Y (see Fig. 1), so that it can move along the axis of the carriage, together with the cutting tool and therefore the pickling contour identification can be carried out in an arbitrary position. With respect to the current state of the art, the aforementioned invention offers the decisive advantage that the negative influences mentioned at the beginning on the accuracy of dimensions are almost irrelevant, since in the aforementioned invention the contour or contours of pickling (in) serves or they serve by themselves as a reference point for colocation.
    In individual application cases it may be convenient that the sensor or camera system does not take any still images at one point, but instead moves along the pickling area and therefore captures the entire course of the pickling contour to then determine a cutting line. This is necessary in particular in the case of curve-shaped cutting models, but it can also be convenient when the stripping contours have to run in a straight line but the contours in the border areas are frayed. In this context it is shown that the device 150 can also be used very well for the automatic quality pickling test. When the quality of the case is not enough then the process can be determined for the purpose of maintenance of the installation.
    By using the PC computer, a quantitative judgment on the quality of the pickling device can also be issued; for this, statistical data can be collected and evaluated. The identification and detection of pickling contours can be indicated in real time on a screen connected to the PC computer; also the evaluation of data can be visualized in that same place in a simple way for the user.
    The example shown by the figures refers in particular to the optimal preparation of a straight line cut in a traverse T between two stripping contours facing K and K ‘. Whenever one is at the beginning or end of a traverse, one will find
    only with a pickling contour and no cutting is necessary. However, the sensor system can be used to detect and check the position and course of a pickling contour compared to the leaf edge. You can also check the quality of the sheet edge or the edge of the sheet.
    5
    The camera described in this case is only an example for an optical sensor system. The sensor system may also have other optical sensor means that act as a contrast, reflection and / or image sensor. For this, if necessary, a laser with a detector unit can also be used. In most cases, however, it is absolutely enough to have a more cost-effective solution with a camera and PC.
    The tests have also shown that in most cases the lighting conditions existing in the installation are sufficient for a sufficient detection and determination of the cutting line. Whenever it is necessary to better illuminate the zones 15 detected by the sensor system or the camera, a device can be provided
    lighting that illuminates the units of flat glass and / or if necessary even examine them in the light.
    Depending on the application case, it may be advantageous to mount the sensor system on a mobile installation part, such as on the carriage of the cutting tool, or
    mount the sensor system statically on the machine body of the installation.
