Definitions
- the invention is based on a device for controlling the movement of a tool along the edge of glass panes, in particular insulating glass panes, with a horizontal conveyor, on which the glass panes are supported by a support device, which defines a pane running plane with its front, which provides the support. are supported with one or more optical sensors which scan the glass panes and with a drive motor for displacing the tool parallel to the plane of the pan transverse to the conveying direction of the horizontal conveyor (1).
- Such a device is known from DE-C-28 16 437.
- a nozzle for sealing the edge joint of insulating glass panes is controlled by a light barrier which is moved along with the sealing nozzle and indicates when the nozzle reaches a corner of the insulating glass pane.
- the light barrier then controls the drive of the nozzle so that the nozzle on the corner of the insulating glass pane is pivoted by 90 ° and then moves along the subsequent section of the edge of the insulating glass pane.
- This type of control is good for rectangular insulating glass panes, but is less suitable for controlling the movement of a Stuff along the edge of individual glass panes or insulating glass panes, which have a shape deviating from the rectangular shape - so-called model panes.
- a numerically controlled drive for the movement of the tool and to store selected shapes of model panes in a data memory and each time a glass pane with a stored one Shape is to be processed, the characteristic data of the shape is read out by a computer and the tool is controlled accordingly.
- the disadvantage here is that glass panes, the shape of which is not saved, cannot be processed automatically, but must be processed by hand.
- Another disadvantage is that the numerical control of the tool has to be communicated in some way when a model pane is to be processed and what shape it has, for example by first detecting the glass panes in terms of shape and size and by attaching one machine-readable data carrier can be coded, which is read in the processing device by a reading device which is connected to the computer which controls the movement of the tool (EP-A-0 252 066), or by a detailed, computer-aided production planning from the beginning for an entire production cycle, the dimensions of those to be processed
- the present invention has for its object to provide a device for controlling the movement of a tool along the edge of glass panes, with which both rectangular glass panes and arbitrarily designed model panes as they come, ie in any order, without a detailed Production planning and can be processed automatically without attaching machine-readable data carriers.
- the invention is based on the fact that the glass panes, preferably standing upright, are conveyed on a horizontal conveyor which is, for example, a conveyor belt or a roller conveyor or horizontally moving supports which support the glass panes. In principle, the glass panes can also be conveyed horizontally.
- the support device can be, for example, an air cushion wall, the front of which defines the disc running plane, or a height-adjustable horizontal line of support rollers (DE-C-30 38 425) which holds the glass discs standing on a horizontal conveyor support near its upper edge, or around a field of support rollers or support rollers, which define the disc running plane with their common front tangential plane, or also one or more conveyor belts or suction conveyor belts driven synchronously with the horizontal conveyor (EP-A-0 222 349), which can also form the horizontal conveyor.
- a height-adjustable horizontal line of support rollers DE-C-30 38 425) which holds the glass discs standing on a horizontal conveyor support near its upper edge, or around a field of support rollers or support rollers, which define the disc running plane with their common front tangential plane, or also one or more conveyor belts or suction conveyor belts driven synchronously with the horizontal conveyor (EP-A-0 222 349), which can also form the horizontal conveyor.
- a drive motor is provided for displacing the tool parallel to the plane of the disk running transversely (in particular at a right angle) to the conveying direction of the horizontal conveyor, which can be, for example, an electric stepping motor.
- one or more electronic line cameras are provided according to the invention, which have an image field made up of one or more lines and are directed against the plane of the pane so that the scanning line (s) of the respective line camera, which is projected onto the pane running plane or onto the glass pane located in the pane running plane, extends or extend at right angles to the conveying direction of the horizontal conveyor.
- the line camera thus sees the extent of the glass pane at right angles to the conveying direction where a scanning line sweeps over the respective glass pane. Since the glass pane is moved transversely to the scanning line by the horizontal conveyor, the respective line camera sees, for example, the height of the glass plate as a function of its length in the course of the conveying movement. In order to determine the shape of the respective glass pane, only the slip-free movement of the glass pane on the horizontal conveyor therefore needs to be recorded in addition to the height supplied by the respective line camera.
- a displacement sensor synchronized with the horizontal conveyor is additionally provided, which permits measurement of the conveying path.
- the encoder can be an incremental rotary encoder, for example, which sits on a shaft which is driven synchronously with the horizontal conveyor and which, in proportion to its movement increments, transmits electrical pulses to an evaluation computer, which also transmits the output signals of the line cameras be fed.
- the evaluation computer thus has full information about the extension of the glass panes in two dimensions, namely in the conveying direction and transversely to the conveying direction, and thus has all the information necessary for the movement of a tool along the edge to control the glass panes.
- the shape of the glass panes is not subject to any restrictions. Both rectangular and arbitrarily controlled model disks can be machined automatically without the sequence in which they are fed to the machining tool having to be determined beforehand.
- the type of processing tool is not important; it can be a nozzle with which the edge joint of an insulating glass pane is sealed, it can be a grinding tool with which a coating is removed along the edge of a glass pane, it can also be a tool with which a prefabricated, plastic spacer in the form of a strand on a Glass pane is applied along its edge.
- the respective line camera is preferably at an angle different from 90 ° to the conveying direction against the
- Disc running plane directed or perpendicular to the conveying direction, but at an angle different from 90 ° to the disc running plane.
- This makes it possible to provide a light source directed against the pane running plane on the same side of the pane running plane as the line camera, and in such an arrangement that the glass panes reflect a substantial part of the light emanating from the light source to the line camera, so that the line camera clearly recognizes the glass pane can.
- a blackened surface is preferably provided on the side of the pane running plane facing away from the light source, which swallows light that has passed through the glass pane, but does not reflect it to the line scan camera.
- a single line scan camera is sufficient to determine the shape of the glass panes.
- the lens of the line scan camera has a predetermined opening angle, and in this opening angle, the size of the pane, namely the extent of the glass panes across the conveying direction must fit.
- the evaluation computer can determine the shape of the glass panes from the combination of the signals from the line scan cameras in a manner corresponding to the output signal of an individual line scan camera.
- Direction of conveyance slidably arranged parallel to the disc running plane and additionally provides a displacement sensor synchronized with the stepper motor, the output of which is also connected to the evaluation computer.
- a line scan camera can proceed transversely to the conveying direction starting from a position in which an edge, in particular the lower edge of a glass sheet standing on a horizontal conveyor, lies in the field of view of the line scan camera be adjusted until the opposite edge of the glass pane appears in the field of view of the line scan camera.
- the evaluation computer then only has to add the measurement number obtained from the output signal of the line camera to the measurement number which is obtained in accordance with the position of the stepping motor from the output signal of the displacement sensor coupled to it. In this way, a second line camera can be saved.
- the line camas are preferably arranged behind the support device and observe the glass panels through a recess in the support device. Behind the support device, they can be better protected against environmental influences and the glass panes remain freely accessible for controls and handling.
- the tool may be displaceable only transversely, preferably at right angles, to the conveying direction of the horizontal conveyor.
- a rotary drive is required - as disclosed in DE-C-28 16 437 - to rotate or pivot the tool an axis perpendicular to the disc running plane; in this case, the evaluation computer is expediently also connected to the rotary drive on the output side and controls the rotary movement of the Tool, such as the rotation of a nozzle when it has reached a corner of an insulating glass pane.
- the evaluation computer preferably transmits not only a control signal to the drive motor which moves the tool transversely to the conveying direction of the horizontal conveyor, but also to the rotary drive of the tool a further signal which indicates the inclination or inclination of the glass pane in relation to the conveying direction .
- This signal can be obtained by differentiating the signal obtained with the aid of the line camera, which contains the dimension of the glass pane measured transversely to the conveying direction, according to the conveying path, which is represented by the output signal of the displacement sensor synchronized with the horizontal conveyor.
- the signal transmitted to the rotary drive is therefore mathematically the first derivative of the signal which is transmitted to the drive motor which shifts the tool transversely to the conveying direction.
- the arrangement of the line scan cameras in relation to the tool can be selected so that the tool is controlled on-line.
- the evaluation computer is preferably equipped with a memory for temporarily storing the observed dimensions of the glass panes, from which the data for the control of the tool are called up with a time delay. It is a major advantage of this measure that the stored data for controlling different tools, which are used one after the other to carry out different processing operations on glass panels, for example grinding and coating, can be called up repeatedly from the memory. Another advantage of this measure is that it allows the measurement resolution to be increased.
- Such a multi-cell line scan camera can differ from a single line Distinguish line scan cameras, for example, in that they contain a multi-cell CCD (CCD array) instead of a single-line CCD as a light-sensitive receiver.
- the image signals recorded in the lines of such a multi-cell charge-coupled receiver can be successively buffered and evaluated, for example in such a way that if the signals of one line are buffered and the signals that have already been buffered on another line are evaluated, those originating from a third line and already evaluated signals are used to control the tool. In this way, the resolving power can be increased in proportion to the number of lines of the line scan cameras.
- FIG. 1 shows the device in a horizontal section
- FIG. 2 shows the device in a front view
- Figure 3 shows the device in a rear view
- FIG. 4 shows a modification of the device shown in FIG. 3 with only one line camera, which is adjustable in height.
- the device has a row of synchronously driven rollers, which are attached to a frame (not shown).
- a wall extends as support device 2, which is carried by the same frame as the horizontal conveyor and is arranged inclined a little to the rear.
- the wall can be designed as an air cushion wall, which has bores from which air is blown out.
- the front side of the wall, over which the horizontal conveyor 1 protrudes, defines a disc running plane for glass panes 4, which are conveyed standing on the horizontal conveyor 1 and leaning against the wall 2 in the direction of arrow 5.
- a black plate 11 is provided, which swallows light passing through the glass pane 4 and at the same time prevents stray light from the front of the wall 2 through the slot 6 back through on the cameras 8 and 9 falls.
- the two cameras have overlapping fields of view 12 and 13, characterized by an opening angle o. They are used to scan the glass pane 4 line by line and are aligned for this purpose in such a way that the scanning line of the upper line camera 8 projected onto the pane running plane 3 or onto the glass plate 4 is aligned with that of the lower line camera 9.
- the distance between the line cameras 8 and 9 from one another and from the horizontal conveyor 1 is predetermined.
- An incremental rotary encoder 15 is attached to a driven shaft 14 of the horizontal conveyor 1, the output signals of which, like the output signals of the two cameras 8 and 9, are fed to an evaluation computer 16.
- the output of the computer is connected to the drive motor 17 of a tool 18, which is movable up and down on essentially vertical guide rods 19 which are parallel to the plane of the disk running and which are arranged behind a further slot 20 in wall 2, which is located at View in the conveying direction 5 is located at some distance behind the slot 6.
- the tool 18 reaches through the slot 20 in order to machine the glass pane 4 along its edge as soon as it reaches the area of action of the tool 18.
- the device works as follows: As soon as a glass pane 4 comes into the field of view 12, 13 of the two line cameras, the two line cameras record the height h of the glass plate, which in the example shown is a model plate, which differs from the rectangular shape in that its upper edge runs obliquely.
- the output signals from the cameras containing the height of the glass pane 4 are fed to the evaluation computer 16, which assigns the successively determined measured values of the height to the simultaneously transmitted measured values of the incremental rotary encoder 15, so that the evaluation computer has information as to the height h of the glass pane 4 changes depending on the feed 1 of the glass pane.
- the data that reflect this dependency are temporarily stored in a memory 21 of the evaluation computer 16 and used with a time delay to control the drive motor 17 of the tool 18.
- the time delay depends on the distance between the tool 18 and the position of the scanning line in the middle of the slot 6; this distance corresponds to a fixed number of up-counts from encoder 15. Instead of starting with a time delay, the delayed response of the
- Control of the drive motor 17 can therefore also be triggered by waiting for the predetermined number of counting pulses from the rotary encoder, which corresponds to the distance of the tool 18 from the position of the scanning lines; this procedure has the advantage that it allows the conveyor to stand still in the meantime.
- its drive motor can also be connected to an incrementally operating rotary encoder 22, the output signals of which are fed to a further input of the evaluation computer 16 for checking.
- the modified exemplary embodiment shown in FIG. 4 differs from the first exemplary embodiment only in that instead of two line cameras, only one line camera 8 is provided.
- the same and corresponding parts are designated in both exemplary embodiments with the same reference numerals.
- the camera provided alone can be moved up and down by a motor 31 on a guide rail 30 running at right angles to the conveying direction 5 and parallel to the wall 2.
- the drive shaft of the motor 31 is connected to an incrementally operating rotary encoder 32, the output signals of which are also fed to the computer 16.
- This modified device works as follows: In the starting position, the camera 8 is positioned so deep that its field of vision definitely captures the lower edge of a glass pane 4. The position of the lower edge is determined by the upper edge of the horizontal conveyor.
- the camera can remain in its predetermined position.
- the upper edge of the glass pane 4 approaches the upper edge of the field of view 12 up to a predetermined one while passing the slot 6
- the camera 8 is automatically moved upward a little, the path being measured by the rotary encoder 32, transmitted to the evaluation computer 16 and taken into account there in the formation of the measurement result. If the upper edge of the glass pane is already outside the court field 12 at the beginning, the camera is raised at the beginning so that the upper edge of the glass pane 4 lies in the field of view 12.
- the invention can be used to control processing operations on the edges of glass sheets, in particular in insulating glass production lines.
