  According to the fourth aspect of the present invention, before starting the operation of the kneading extruder and the device for removing the cured product in the worm, an operation check test using a test piece of a simulated color corresponding to the cured product color was performed, and the cured product was detected. Check whether the controller outputs an abnormal signal to be output in the case, and output an interlock release signal that enables the kneading extruder to operate only when an abnormal signal is output by the operation check. Thus, since the operation of the kneading extruder cannot be started unless an abnormal signal is output, in addition to the effects of the first to third inventions, in the manufacturing process of the worm using the kneading extruder, Detection and removal of the cured product can be reliably performed by the removal device for the cured product in the worm.

  According to the fifth aspect of the present invention, the simulated color member corresponding to the cured product color is disposed in the non-inspection region in the field of view of the imaging device, and continuously or intermittently during operation of the removal device for the cured product in the worm. In addition to the effects of the first to fourth inventions, in addition to the effects of the first to fourth inventions, detection of a hardened material caused by the imaging device Defects can always be monitored during operation of the removal device for the cured product in the worm.

  Hereinafter, the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing a schematic configuration of an apparatus for removing a cured product in a worm according to an embodiment of the present invention. FIG. 2 is a perspective view of a part of the worm-cured cured product removing device shown in FIG. 1 as viewed from the front upper side, and FIG. FIG. 4 is a diagram showing a monitor screen of the control device during operation of the removal device for the cured product in the worm.

  The removal device 1 for the cured product in the worm according to the present embodiment shown in FIGS. 1 to 3 is a foreign material that is kneaded by a kneader in the kneading extruder 60 in the previous step and is a foreign matter present in the worm 30 discharged to the outside. It is for removing the thing 31, and is provided with the conveyance conveyor 2 into which the worm 30 discharged from the kneading extruder 60 is introduced upstream.

  The transport conveyor 2 transports the worm 30 introduced on the upstream side horizontally at a constant speed in the left direction in FIG. 1, and drops the worm 30 reaching the downstream end portion downward. As shown in FIGS. 2 and 3, a chute 12 is disposed on the downstream side of the transport conveyor 2, and the worm 30 that has reached the downstream end of the transport conveyor 2 falls in the chute 12 and falls into the chute 12. It is taken out from below and supplied to the subsequent process.

  As shown in FIGS. 1 to 3, two imaging devices 3 a and 3 b are arranged side by side in the transverse direction of the transport conveyor 2 at the upper downstream side of the transport conveyor 2. CCD cameras are used as the imaging devices 3a and 3b, and the imaging devices 3a and 3b are arranged at a predetermined distance from the conveyor 2 in order to prevent lens fogging due to the volatile solvent from the worm 30. In consideration of the accuracy of the minimum detected object, it is disposed at an upper position separated from the conveyor 2 by about 80 cm.

  The two imaging devices 3a and 3b are arranged side by side in the transverse direction of the transport conveyor 2, so that the captured images can be obtained with the entire inspection areas 51a and 51b shown in FIG. I try to get it. Although not shown, the inspection areas 51a and 51b by the imaging devices 3a and 3b are illuminated with light from a light source so that a good captured image can be obtained.

  As shown in FIGS. 2 and 3, the periphery of the transport conveyor 2 is covered with a long box-like cover body 10 that prevents scattering of dust, volatile solvents, and the like, and is placed on the chute 12 from the upstream side of the transport conveyor 2. The transport route leading up to is shielded from the outside. On the other hand, the cover body 10 is provided with an opening 11 that opens to the outside only in the vicinity of the inspection areas 51 a and 51 b by the imaging devices 3 a and 3 b, and is disposed above the cover body 10 through the opening 11. The worm 30 on the conveyor 2 can be imaged by the imaging devices 3a and 3b.

  On one side of the transport conveyor 2 at the position of the opening 11 of the cover body 10, a blower 20 that blows air in the transverse direction of the transport conveyor 2 is disposed. In addition, an air discharge device 21 that discharges air from the blower 20 is disposed on the other side of the conveyor 2 so as to face the blower 20. The air discharge device 21 includes an air discharge port 22 that is an inlet of air from the blower device 20 and an air discharge pipe 23 that communicates with the air discharge port 22, and dust rising from the conveyor 2 can also be collected together with air. It is like that.

  As shown in FIG. 2, an air curtain 24 is provided between the transport conveyor 2 and the imaging devices 3 a and 3 b arranged above the conveyor 2 by air blowing from the air blower 20 toward the air discharge port 22 of the air discharge device 21. It is formed. Thereby, dust and volatile solvent rising from the conveyor 2 that conveys the worm 30 are shielded from above by the air curtain 24, so that the dust and volatile solvent may come into contact with the lenses of the imaging devices 3a and 3b. Absent. Accordingly, detection defects of the cured product 31 due to lens contamination, lens fogging, and the like due to dust or volatile solvent rising from the conveyor 2 coming into contact with the lenses of the imaging devices 3a and 3b are reliably prevented.

  As shown in FIG. 1, image signals from the imaging devices 3a and 3b are transmitted to a control device 4 having an image processing function. The control device 4 is composed of a computer having a storage device (not shown), an arithmetic processing device, an input device, and the like. The storage device includes a program for image processing and the color and curing of the worm 30 according to the worm product number. Data of the color of the product 31, and other programs necessary for controlling the conveyor 2, the cured product removing device 6, the kneader board 45, and the like are stored. In addition, the control device 4 includes a monitor 5 that displays images taken by the imaging devices 3a and 3b as shown in FIG. 4 and a controller that can adjust the imaging devices 3a and 3b.

  Images captured by the two imaging devices 3a and 3b are subjected to image processing by the control device 4, and when a cured product 31 in the worm 30 is detected as an image processing result, the control device 4 uses the result as an abnormal signal. Output.

  The image processing by the control device 4 is performed from the imaging devices 3a and 3b by using the color of the white worm 30 and the color of the yellow cured product 31 in the worm of the product number read and set in advance as reference data. This is performed by performing an analysis process with an arithmetic unit in comparison with the captured image data. As such an image processing method, a generally known method such as extraction of a threshold value of the shape outline of the cured product 31 based on color data can be applied.

  As a result of the image processing, when the control device 4 detects the cured product 31, the control device 40 transmits a drive signal to the cured product removing device 6 shown in FIGS. As shown in FIG. 3, the cured product removing device 6 includes a cured product tray 7 that can slide back and forth by a cylinder mechanism to the drop position of the worm 30 in the chute 12 disposed on the downstream side of the conveyor 2. Yes.

  The cured product tray 7 has a SUS square dish shape, and is disposed obliquely so that the taken-out cured product 31 does not spill into the chute 12 so that the front end is slightly upward with respect to the rear end. It is installed.

  The cured product tray 7 is normally located outside the chute 12, but when the control device 4 detects the cured product 31, the cylinder mechanism is driven based on the drive signal transmitted from the control device 4, It slides forward into the chute 12 from an opening 12a provided on the rear side surface of the chute 12 shown in FIG.

  The hardened material tray 7 starts to slide forward at a predetermined timing after the hardened material 31 that has entered the inspection areas 51a and 51b of the imaging devices 3a and 3b on the conveyor 2 is detected by the image processing of the control device 4. Then, after receiving the cured product 31 falling from the downstream end of the transport conveyor 2 while being located in the chute 12, it immediately slides back to a fixed position outside the chute 12 and returns.

  As described above, when the worm 30 conveyed on the conveyor 2 is monitored by the imaging devices 3a and 3b for the presence or absence of the cured product 31, and when the cured product 31 is detected by the image processing by the control device 4, the cured product is detected. By removing the cured product 31 from the worm 30 by the removing device 6, the cured product 31 in the worm 30 can be reliably and quickly removed with high accuracy, and the quality of the product can be stabilized.

  In the present embodiment, as described above, the storage device of the control device 4 stores the data of the color of the worm 30 and the color of the cured product 31 corresponding to the product number of the worm 30, and the product number of the worm 30 to be manufactured is stored. By performing setting input from an input device such as an input key or a mouse, the color data of the worm 30 and the color of the cured product 31 stored in the storage device are read out, and image processing is performed based on the data. I have to.

  The worm 30 typically has a white color, and the cured product 31 typically has a yellow color. However, the color varies depending on the product number, and the imaging device is used during image processing. If the reference data of the color of the worm 30 and the color of the cured product 31 compared with the captured image data 3a and 3b are always the same, the detection accuracy of the cured product 31 by image processing has a certain limit.

  On the other hand, in the present embodiment, by inputting the setting of the product number of the worm 30 to be manufactured, the color data of the worm 30 and the color of the cured product 31 of the product number are read from the storage device, and image processing is performed with reference to the data. Therefore, by performing appropriate image processing according to each product number, the cured product 31 in the worm 30 of each product number can be reliably removed with high accuracy, and the quality of the product of each product number Can be stabilized.

  Further, in the present embodiment, as shown in FIG. 1, the control device 4 is provided with a monitor 5 for displaying images taken by the imaging devices 3a and 3b. The monitor 5 has a display screen as shown in FIG. The imaging screen 50a of the imaging device 3a and the imaging screen 50b of the imaging device 3b are displayed. In the imaging screens 50a and 50b, inspection areas 51a and 51b in the visual field of the imaging devices 3a and 3b are displayed, respectively, and non-inspection areas 52a and 52b outside the inspection areas 51a and 51b in the visual field are displayed. Yes.

  In the non-inspection regions 52a and 52b, members 53a and 53b having simulated colors corresponding to the color of the cured product 31 are always disposed, and are continuously or intermittently operated during the operation of the in-worm cured product removing device 1. Further, the control device 4 performs image processing of the captured images of the non-inspection areas 52a and 52b by the imaging devices 3a and 3b, and outputs the detection results of the members 53a and 53b having the simulated colors.

  When the control device 4 normally detects the simulated color members 53a and 53b as a result of the image processing, the control device 4 continues the operation of the in-warm cured product removing device 1 as it is. On the other hand, when the control device 4 does not detect the simulated color members 53a and 53b as a result of the image processing, the control device 4 notifies the abnormality by sounding a buzzer or lighting an inspection display.

  This abnormality is considered to be caused mainly by malfunctions in the imaging devices 3a and 3b, lens contamination and lens fogging caused by contact with dust and volatile solvents, etc. on the lens. If it continues, possibility that the detection defect of the hardened | cured material 31 which is the same color as the members 53a and 53b of a simulation color will arise becomes high.

  Therefore, when an abnormality is informed by the buzzer sounding or the lighting of the inspection display, the controller 4 performs the necessary operation for dealing with the cause of the abnormality such as the adjustment of the imaging devices 3a and 3b, and as a result, the control device 4 When the simulated color members 53a and 53b are normally detected, the operation of the in-warm cured product removing device 1 is continued as it is. Alternatively, the operation of the kneading extruder 60 and the in-warm cured product removing apparatus 1 is stopped, and the operation is restarted after performing a required operation for eliminating the abnormality.

  In this manner, the members 53a and 53b having simulated colors corresponding to the color of the cured product 31 are disposed in the non-inspection areas 52a and 52b in the field of view of the imaging devices 3a and 3b, and the non-inspection areas 52a by the imaging devices 3a and 3b are disposed. , 52b is subjected to image processing and the detection result of the simulated color is output, so that the detection failure of the cured product 31 caused by the imaging devices 3a, 3b is detected during the operation of the removal device 1 for the cured product in the worm. Can always be monitored.

  Moreover, in this embodiment, the interlock mechanism for performing the detection of the hardened | cured material 31 by the removal apparatus 1 of the hardened | cured material in a worm reliably is provided. This interlock mechanism utilizes the test piece 40 of FIG. 5 having a simulated color corresponding to the color of the cured product 31, and before the start of the operation of the kneading extruder 60 and the cured product 1 in the worm, The test piece 40 is positioned in the inspection areas 51a and 51b on the transport conveyor 2 and imaged by the imaging devices 3a and 3b. Although FIG. 5 shows the case where the test piece 40 is positioned in the inspection area 51a of the imaging device 3a, the test piece 40 is similarly positioned in the inspection area 51b of the imaging device 3b and imaging is performed by the imaging device 3b. .

  Then, in a state where the test piece 40 is positioned in the inspection areas 51a and 51b, an operation check is performed to determine whether or not to output an abnormal signal that is output when the control device 4 detects the cured product 31. When the control device 4 outputs an abnormal signal due to the operation confirmation, the control device 4 causes the kneader extruder 45 of FIG. 1 which is the control panel of the kneading extruder 60 to operate the kneading extruder 60. Send. When the kneader board 45 receives the interlock release signal, the kneading extruder 60 is brought into an operable state.

  On the other hand, when the control device 4 does not output an abnormal signal due to the operation confirmation, the control device 4 does not transmit an interlock release signal to the kneader board 45. In this case, the operation start is locked so that the kneading extruder 60 cannot be started even if the kneader board 45 is operated.

  When the control device 4 does not output an abnormal signal due to the operation check, the main factor is considered to be an adjustment failure of the imaging devices 3a and 3b. In this state, the operation of the removal device 1 of the cured product in the worm is temporarily performed. When started, there is a high possibility that defective detection of the cured product 31 having the same color as the test piece 40 will occur.

  Therefore, in this case, after performing necessary operations such as adjustment of the imaging devices 3a and 3b, the test piece 40 is again positioned in the inspection areas 51a and 51b on the transport conveyor 2 and imaged by the imaging devices 3a and 3b. To confirm the above operation. As a result, when the control device 4 outputs an abnormal signal, the control device 4 transmits an interlock release signal to the kneader board 45, and the kneader board 45 receives the interlock release signal. Is assumed to be operable.

  Thus, since the removal device 1 for the cured product in the worm of the present embodiment includes the interlock mechanism described above, the removal device for the cured product in the worm in the manufacturing process of the worm 30 using the kneading extruder 60. 1 can reliably detect and remove the cured product 31.

  The operation sequence of the device for removing a cured product in worm 1 of the present embodiment having the above configuration will be described below with reference to the flowchart of FIG.

  First, before starting the operation of the kneading extruder 60 and the cured product 1 in the worm, the operation of the cured product 1 in the worm is checked in order to release the interlock mechanism. The test piece 40 of FIG. 5 is positioned in the inspection areas 51a and 51b on the transport conveyor 2 and imaged by the imaging devices 3a and 3b, and an abnormal signal output when the control device 4 detects the cured product 31 is output. If the control device 4 detects the test piece 40 and outputs an abnormal signal as a result of confirming whether or not the operation has been performed, the control device 4 transmits an interlock release signal to the kneader board 45. Thereby, the kneading extruder 60 is brought into an operable state (S1).

  On the other hand, if the control device 4 does not output an abnormal signal, after performing necessary operations such as adjustment of the imaging devices 3a and 3b (S2), the operation returns to S1 and the operation check by the test piece 40 is performed again. .

  When the kneading extruder 60 is in an operable state, the operation of the kneading extruder 60 and the worm-cured cured product removing apparatus 1 is started, and the manufacture of the worm 30 is started (S3).

  After the operation is started, the control device 4 performs image processing on the images taken by the imaging devices 3a and 3b in the inspection areas 51a and 51b in FIG. (S4).

  As a result of the image processing, if the cured product 31 is not detected in the inspection areas 51a and 51b and the worm 30 is a non-defective product, the simulated color members 53a and 53b in the non-inspection areas 52a and 52b in FIG. The detection result is output (S5).

  On the other hand, when the cured product 31 is detected in the inspection areas 51a and 51b as a result of the image processing, the control device 4 transmits a drive signal to the cured product removing device 6, and the cured product removing device 6 is controlled by the control device. The cylinder mechanism is driven based on the drive signal transmitted from 4, and the cured product tray 7 slides forward into the chute 12 from the opening 12a on the rear side surface of the chute 12 shown in FIG. The cured product 31 falling from the end is received, and then immediately slides backward to return to a fixed position outside the chute 12 (S6). Thereafter, returning to S4, the monitoring of the cured product 31 in the worm 30 conveyed on the conveyor 2 is continued.

  In S5, when the control device 4 detects the members 53a and 53b having the simulated colors in the non-inspection areas 52a and 52b in FIG. 5, the process returns to S4 and the cured product 31 in the worm 30 conveyed on the conveyor 2 is returned. Continue monitoring.

  On the other hand, when the control device 4 does not detect the simulated color members 53a and 53b as a result of the image processing, the control device 4 notifies the abnormality by the buzzer sounding and the check display lighting (S7).

  In this case, after performing a necessary operation for dealing with the cause of the abnormality such as adjustment of the imaging devices 3a and 3b, the control device 4 confirms the detection of the members 53a and 53b of the simulated color again (S8). As a result, when the control device 4 detects the simulated color members 53a and 53b normally, the inspection display is turned off (S10), and the process returns to S4 and the cured product 31 in the worm 30 conveyed on the conveyor 2 is returned. Continue monitoring.

  On the other hand, when the control device 4 does not detect the simulated color members 53a and 53b, a necessary operation for coping with the cause of abnormality such as adjustment of the imaging devices 3a and 3b is performed (S9) and S8. Returning to step S4, the controller 4 confirms the detection of the members 53a and 53b of the simulated color.

  If the control device 4 does not detect the simulated color members 53a and 53b in S5 and the control device 4 notifies the abnormality by the buzzer sounding and the lighting of the inspection display in S7, the kneading extruder 60 and the in-warm hardening are performed. The operation of the object removal apparatus 1 may be stopped and the operation may be resumed after performing a required operation for eliminating the abnormality.

  Finally, when the production of the worm 30 is finished, the operations of the kneading extruder 60 and the worm-cured cured product removing apparatus 1 are stopped (S11).

  Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. For example, the control device 4 may be composed of an image processing computer having an image processing function of captured images by the imaging devices 3a and 3b and a separate computer that controls other external devices. .
