Definitions

  • the present invention pertains to a method for detecting the displacement of a coating pattern and a method for correcting said displacement, in which the coating delay inherent in the spray gun or the deviation of an actual coating pattern from a supposedly ideal coating pattern are detected when applying a coating material such as an adhesive or a coating agent by spraying it from a spray gun onto workpieces being moved by a conveyer or the like, then the deviation is corrected automatically.
  • a coating material such as an adhesive or a coating agent
  • FIG. 1 represents a conveyer device, said conveyer device 1 advancing in the direction of the arrow by the application of a driving source which is not illustrated.
  • 2 is a workpiece being moved by the foregoing conveyer device 1 , and said workpieces 2 are continuously supplied at given intervals.
  • 3 is a spray gun for spraying an adhesive 5 which is pressure fed from an adhesive feed device 4 , toward the workpiece 2 . Said spray gun 3 will be described in detail later, but an air-driven spray gun is used as an actual example.
  • the electromagnetic valve 6 is an electromagnetic valve [ solenoid valve? -- Tr. Ed. ], said electromagnetic valve 6 turning on and off the supply of air 8 from an air supply 7 for driving the spray gun 3 , and thus controlling the operation of the spray gun 3 .
  • 9 is a speed sensor for detecting the speed of the conveyer 1 , then the signal detected by said speed sensor 9 is input and processed in a control device 10 and monitored by a speed meter incorporated in the control device 10 .
  • the work sensor 11 is a work sensor that detects the presence of the workpiece 2 .
  • Said work sensor 11 senses the leading end of the moving workpiece 2 , transmits a signal, then stops transmitting the signal at the point when the workpiece 2 is detected.
  • the work sensor 11 is installed at a position up-stream by a set distance " a " from the location of the center of the nozzle of the spray gun 3 , because of structural limitations at the installation site [ presumably the limitation is the installation space that is available -- Tr. Ed. ]. That is, the distance " a " is the distance between the work sensor 11 and the spray gun 3 .
  • the structure and action of the aforementioned spray gun 3 are as follows (with reference to Figure 4): If the electromagnetic valve 6 is turned on and air 8 is supplied from the air supply 7 to the spray gun 3 , the piston 12 of the spray gun 3 is pushed up against the force of a spring 13 , a needle 14 which is directly connected to the piston 12 is also pushed up, the needle valve mechanism is opened, and the adhesive 5 gushes out of the nozzle of the spray gun 3 onto the workpiece 2 , and is thus applied to the workpiece 2 . 16 indicates the adhesive applied to the workpiece 2 .
  • the piston 12 is pushed down by the restoring force of the spring 13 , the needle valve mechanism is closed, and spraying of the adhesive 5 ends.
  • the restoring force of the spring 13 can be adjusted by the distance that screw 15 is screwed in or out.
  • air-driven spray gun is described in this example, however, not only air-driven spray guns but also electromagnetic direct-acting spray guns can be used. It is also true, however, that electromagnetic direct-acting spray guns are disadvantageous from the standpoint of the space they take up, since a large electromagnetic coil is needed to provide a given driving force when handling a fluid of high viscosity and at high pressure such as an adhesive. In contrast to this, air-driven spray guns can be designed to be small and compact, which is advantageous when handling fluids of high viscosity and at high pressure.
  • the speed v of the conveyer 1 is first set with reference to the preceding process and subsequent process, which are not illustrated. This speed v is input to the control device 10 artificially or as a relevant indication signal from the preceding or subsequent process device.
  • the non-illustrated driving device for the conveyer 1 is then adjusted to operate at speed v based on the speed v indication signal from the control device 10 .
  • the speed v of the conveyer 1 is monitored by the speed meter in the control device 10 as a signal from the speed sensor 9 .
  • the adhesive coating location of the workpiece 2 is determined. Specifically, a coating start position A that is a certain distance b away from the leading end of the workpiece 2 , and a distance " c " over which the adhesive is to be applied to the workpiece 2 are determined.
  • These location values are then input by calculating the time it takes for the coating start position A to advance to a location directly under the spray gun 3 after the leading end of the workpiece has been detected by the work sensor 11 , i.e., time T1 during which the coating start position A advances by the distance " a " from the nozzle center position of the spray gun 3 to the work sensor 11 , and time T2 (corresponding to distance " c ") during which the spray gun 3 is kept open and the adhesive is applied, i.e., the values T1 and T2 are input artificially into the control device 10 .
  • the coating work begins. If the leading end of the workpiece 2 is detected (i.e., a trigger signal is generated) by the work sensor 11 , the control device 10 transmits an "open" signal to the electromagnetic valve 6 after time lapse T1 after the leading end of the workpiece 2 has been detected, which opens the electromagnetic valve 6 .
  • the air 8 for driving the spray gun 3 is then supplied to the spray gun 3 ; the piston 12 of the spray gun 3 is pushed up against the force of the spring 13 ; the needle 14 directly connected to the piston 12 is also pushed up and the needle valve mechanism is opened; and the adhesive 5 gushes out of the nozzle of the spray gun 3 onto the workpiece 2 and is thus applied to the workpiece 2 .
  • the control device 10 ceases actuation of the electromagnetic valve 6 and thus turns off the electromagnetic valve 6 , so that the air pressure which has kept the piston 12 up, is released, the piston 12 is pushed down by the restoring force of the spring 13 , the needle valve mechanism is closed, and coating with the adhesive is terminated.
  • Displacements of the coating pattern of this kind are inherent to the use of the spray gun. They are caused by factors such as the time it takes for the piston 12 to be pushed up against the force of the spring 13 after the driving air is supplied. In the case of an air-driven spray gun, the sliding resistance of the piston 12 and the needle 14 , the distance " h " from the nozzle tip to the workpiece, and the pressure of the coating fluid, tend to vary in a delicate and indirect manner due to the passage of time and/or friction. Accordingly, even a spray gun produced under the best quality control conditions cannot avoid this delay in the coating time, even though there are some differences from one individual product to another. A coating delay of this kind also occurs even if an electromagnetic direct-acting spray gun is used, although there are some differences in the delay value.
  • This shifting of the coating pattern causes the same delay times when seen in terms of time, but does not vary with respect to a change in [ the conveying ] speed.
  • the displacement of the coating pattern appears to be proportionately larger with respect to the speed as the production speed increases.
  • pattern displacements of the kind discussed above are the notable causes of lower quality in products that require coating quality of high precision. Clearly, then, improvements are sorely needed.
  • a trial coating run is carried out and the results are examined visually by the worker.
  • the distance of the delay from the ideal coating position to the actual coating position is measured and used to calculate the delay time, then time T1 and time T2 that have been set in the control device 10 are corrected manually by the worker.
  • Operations like this take a lot of time and labor, e.g., a tremendous amount of time used to be required when starting production of a new product, changing the coating pattern, or repairing or exchanging the spray gun.
  • visual examination can be difficult depending on the type of workpiece and/or the type of coating material, which make it difficult to make highly accurate corrections.
  • the present invention was developed in response to these problems, thus the goal of the present invention is to provide a method for detecting the coating delay inherent in the use of a spray gun and/or the displacement of an actual coating pattern from a supposedly ideal coating pattern, and also to provide a method for automatically correcting said displacement, when applying a coating material such as an adhesive or a coating agent by spraying it from a spray gun onto workpieces being moved by a conveyer or the like.
  • the present invention pertains to a method for detecting the displacement of the coating pattern, characterized in that the deviation value of the actual coating time from a set coating time value is determined by comparing the set coating time values to open and close the spray gun, which have been set in advance in a device for controlling the coating device, with the actual coating time information obtained from a sensor used to monitor the state of the spray coating procedure.
  • the present invention pertains to a method for correcting the displacement of the coating pattern, characterized in that the deviation value of the actual coating time from the set coating time value is determined by comparing the set coating time values to open and close the spray gun, which have been set in advance in a device for controlling the coating device, with the actual coating time information obtained from a sensor for monitoring the state of the spray coating procedure; and in that said controlling device is configured so as to output a spray signal to the spray gun by altering the set coating time value by the determined deviation.
  • the present invention pertains to a method for detecting the displacement of a coating pattern and a method for correcting said displacement as part of a method for spray coating moving workpieces with a coating material from a spray gun by the procedure mentioned earlier, and hence can provide a spray coating method of extremely high quality with no coating delay.
  • the set coating time value at a line speed v that has been set in a control device for a coating line based on the design value for a coating pattern, i.e., time ( T1 ) until the spray start signal is output to the spray gun after the workpiece is detected by the work sensor, and time ( T2 ) during which the spray gun is carrying out the spray coating process, are compared with the actual coating time information ( ts and t2 ) obtained from a sensor used to monitor the state of the coating spray process in accordance with the above-mentioned times, then the respective deviations are determined, whereby the displacement of the coating pattern can be detected. Moreover, the positional deviation value of the coating pattern is fed back to the set coating time value, then the set coating time value is shifted and modified by said deviation value, whereby the ideal coating pattern can always be obtained automatically.

  • Figure 2 is an explanatory perspective diagram which illustrates the principal components of the present invention, similar to those of Figure 1.

  • the work sensor 11 is installed at a position upstream by distance " a " from the location of the center of the nozzle of the spray gun 3 , because of structural limitations at the installation site. That is, the distance " a " is the distance between the work sensor 11 and the spray gun 3 .
  • the 21 is a sensor used to monitor the adhesive 16 being applied to the surface of the workpiece 2 .
