Definitions
- the invention relates to an application system for a pasty mass, in particular for an adhesive or a sealant, with an application device for producing a directed in a Massestrahlraum mass jet of pasty mass applicator and with an optical monitoring device for monitoring the Massestrahlraum.
- Such application systems are used to apply pasty masses, such as adhesives or sealants, on workpieces.
- application systems are widely used with robots in the automotive industry.
- the application device is moved by means of the robot, for example along an adhesive seam to be applied, and the mass jet emerging from the application nozzle is directed onto the workpiece.
- there is no monitoring of the order so that the workpieces must be subsequently subjected to a quality control. It is possible that job errors are detected late, if a large number of workpieces has already been processed incorrectly.
- the invention is based on the idea of monitoring a deflection of the mass beam from the desired nominal mass beam direction and promptly indicating to the user that from two different spatial directions, which respectively deviate from the desired mass beam direction, one light beam is directed to the mass beam and observed becomes. If the mass beam is undesirably deflected to the side out of the desired mass beam direction, then the point of impact of at least one of the two light beams moves on the mass beam, which in turn can be observed and evaluated.
- the application device and the monitoring device are fixedly connected to one another and jointly movable by means of a mechanical drive device, for example by means of a robot.
- a monitoring of the mass beam can then take place continuously during the entire order process.
- the monitoring device is mounted stationary, while only the application device is movable by means of a mechanical drive device.
- the applicator device can be readjusted before continuing with the order.
- the feeding of the application device to the monitoring device can, for example, always be carried out between the machining of two workpieces by the application device moving into a stationary station containing the monitoring device.
- the inventive principle presupposes that the transmission directions of the light beams are arranged transversely to one another and in each case transversely to the mass beam. The highest accuracy is obtained when the two transmission directions are substantially perpendicular to each other and each aligned substantially perpendicular to the mass direction of rotation.
- the first light receiver is designed to observe an impact point of the first light beam on the mass beam
- the second light receiver is designed to observe an impact point of the second light beam on the mass beam.
- the transmitting and receiving devices it is possible for the transmitting and receiving devices to each be designed to measure an angle between the respective light beam and a line running through its impact point on the mass beam and a defined measuring point in or on the associated light receiver. The observation of the mass beam then takes place according to the triangulation principle, according to which at least one of the measured angles changes when the mass beam is deflected out of its desired mass-beam direction.
- the light emitter in each case transmit pulsed light, in particular pulsed laser light, to the respective impingement point on the mass beam and that the transmitting and receiving devices are respectively designed for measuring the propagation time of the pulsed light.
- the transit time of the light from the light transmitter to the point of impact on the mass beam and from there to the respective light receiver is measured.
- the light transit time is in linear dependence on the distance of the impingement of the light emitter and the light receiver, so that a deflection of the mass beam from the desired mass beam direction in the change of the light propagation time of at least one of the transmitting and receiving devices affects.
- the transmitting and receiving devices each have a light barrier and are designed for the measurement of a light beam interruption by the mass beam.
- the first and the second light beam can be designed so that they have a width at the mass beam in each spatial direction which is at most as large as the extent of the mass beam in this spatial direction.
- the light barriers can then be positioned, similar to a crosshair, so that the mass beam always interrupts them when it runs in the desired mass beam direction. As soon as the light receiver of one of the light barriers detects light, this is a sign that the mass beam has been deflected out of its desired mass beam direction.
- the first and the second light beam each have a width in at least one spatial direction, which is greater than the extent of the mass beam in this spatial direction, and that the associated light receiver for the reception of light over the entire width of the relevant Light beam is formed. This makes it possible not only to obtain the binary information "deflected / not deflected", but also to measure the degree of a possible deflection of the mass beam.
- FIG. 1 a, b, c an application system according to a first embodiment in a side view and in two perspective views;
- the application system 10 according to the first exemplary embodiment illustrated in FIGS. 1 a, b, c has an application device 12, which is equipped with an application nozzle 14.
- the application nozzle 14 is used to apply a mass jet 16 of a pasty adhesive or sealant to a workpiece.
- the mass beam 16 is shown extending in a vertical mass beam direction 18.
- the application system 10 also has a monitoring device 20, which has a first and a second transmitting and receiving device 22,24.
- the first transmitting and receiving device 22 has a first light transmitter 26 and a first light receiver 28.
- the first light transmitter 26 transmits a first light beam 30 in a direction perpendicular to the mass beam direction 18 first transmission direction 32 in the direction of the mass beam 16.
- the second transmitting and receiving device 24 has a second light transmitter 34 and a second light receiver 36.
- Light emitter 34 transmits a second light beam 38 in a second transmission direction 14 onto the mass beam 16, which is oriented both substantially perpendicular to the mass radiation direction 18 and to the first transmission direction 32.
- the two light transmitters 26, 34 are of identical construction, so that the two light beams 30, 38 correspond in their intensity and shape.
- the two light receivers 28, 36 observe the points of impact 42a, 42b of the associated light beams 30 and 38 on the mass beam 16 and respectively measure an angle CM, C (2, which is enclosed by the respective light beam 30, 38 and a line 44, which passes through the respective point of impact 42a, 42b and a defined measuring point 46 on or in the associated light receiver 28, 36.
- the mass beam 16 is shown in the drawing at least one of the angles CM, C (2, and an evaluation of the monitoring device 20 detects a deviation of the mass-beam direction of the setpoint is changed by perpendicular, downwardly extending Massestrahlraum 18 by unwanted external influences or an error in the application system 10 in another direction
- the monitoring device 20 thus operates according to the triangulation principle, and its light transmitters 26, 34 are preferably lasers.
- the application system 10 ' according to the second exemplary embodiment (FIGS. 2 a, b, c) has essentially the same structure as the application system 10 according to the first embodiment, so that identical components are provided with the same reference numerals. However, it does not work according to the triangulation principle, but measures the transit time of the light, which is present here as pulsed laser light. The transit time of the two light beams 30, 38 from the respective light transmitter 26, 34 to the respective impingement point 42 a, 42 b and back to the light receiver (not shown) is measured. If the mass beam 16 is deflected out of the direction of mass beam direction 18 shown in the drawing, which extends vertically downwards, this is reflected in a change in at least one of the transit times measured by one of the two transmitting and receiving devices 22, 24.
- the application system 10 "according to the third exemplary embodiment (FIGS. 3 a, b, c) also makes use of essential principles of the first exemplary embodiments, so that the same components are provided with the same reference numerals here as in the first exemplary embodiments
- the transmitting and receiving devices 22,24 each have a beam photoelectric sensor 48,50 the first light transmitter 26 and the first light receiver 28, while a second beam light barrier 50 has the second light emitter 34 and the second light receiver 36.
- the two light beams 30,38 are again perpendicular to each other and perpendicular to the mass beam 16 aligned and focused on this and offset each other by a small height difference, so that they form a crosshair in plan view and in the illustrated in the drawing vertically downward direction of mass beam 18 both of the mass beam 16th to be interrupted.
- Their cross section is in each case smaller than the cross section of the mass beam 16, so that at a sufficiently large deflection of the mass beam 16 from the shown in the drawing, vertically downwardly pointing mass beam direction 18 at least the interruption of one of the light beams 30,38 is canceled, so that the associated Light receiver 28,36 receives light and transmits this signal to the evaluation.
- the application device 12 and the monitoring device 20 are each firmly connected to each other.
- the orientation of the transmission directions 32, 40 in the exemplary embodiments shown is perpendicular to one another and not perpendicular to the mass-radiation direction 18.
- the transmission directions 32, 40 may rather include different acute angles with one another and with the mass-radiation direction 18.
- the invention relates to an application system 10,10 ', 10 "for a pasty mass, in particular for an adhesive or a sealant, with an application nozzle 14 for generating a directed in a mass beam direction 18 mass beam 16 of the pasty mass Having an application device 12 and with an optical monitoring device 20 for monitoring the Massestrahlraum 18th
