The CPU 90a controls the operations of the sprocket 21, the fiber sensor 37, the actuator 30, the air cushion cylinder 40, and the printer 80. The CPU 90b controls the operation of the load cell 33, the laser sensor 50, the microphone 60, the front weighing sensor 70a, and the rear weighing sensor 70b. The display unit 92a is configured to be able to display the operating states of the sprocket 21, the fiber sensor 37, the actuator 30, the air cushion cylinder 40, and the printer 80. The display unit 92 b is configured to be able to display the results measured by the load cell 33, the laser sensor 50, the microphone 60, and the weighing sensor 70. The input units 93a and 93b are configured to be able to input various control conditions. In the present embodiment, graphic analog controllers RJ-800 manufactured by Keyence Corporation are used as the first controller 9a and the second controller 9b, respectively.

  Next, a method for evaluating the quality of the aerosol container 10 using the quality evaluation apparatus 1 having the above configuration will be described. The quality evaluation of the aerosol container 10 is performed via the load cell 33, the laser sensor 50, the weighing sensor 70, and the microphone 60.

  First, quality evaluation via the load cell 33 will be described. FIG. 13 is a flowchart showing the control of the first controller 9a. First, when the switch is turned on, the first controller 9a operates the sprocket 21 by rotating a drive motor (not shown) (step S301). When the sprocket 21 is actuated, the chain 22 rotates, and the bucket holder 23 moves in the transport direction A along with this.

  When the plurality of bucket holders 23 are moved, they are disposed below the air cushion cylinder 40. In the first evaluation area 501, the first bucket holder 23a is located below the air cushion cylinder 40, and in the second evaluation area 502, the second bucket holder 23b is located below the air cushion cylinder 40. Further, the bucket 100 and the aerosol container 10 are disposed below the measurement actuator 30a. Further, when the fiber sensor 37 detects the movement of the bucket holder 23, the sprocket 21 stops.

  Next, the first controller 9a operates the air cushion cylinder 40 (step S302). When the air cushion cylinder 40 is actuated, the piston rod 41 protrudes downward as shown in FIG. 14, and presses the slide guide 234 of the bucket holder 23 located below the air cushion cylinder 40. When the slide guide 234 is pressed, the pair of opening / closing plates 231 and 231 open to the left and right, and the bucket 100 held by the bucket holder 23 is released. When the bucket 100 is released, it is placed on the support member 42.

  Next, the first controller 9a operates the actuator 30 (step S303). When the actuator 30 is operated, the piston rod 32 protrudes downward. When the piston rod 32 protrudes, the load cell 33 presses the bottom of the aerosol container 10 in the measurement actuator 30a. When the aerosol container 10 is pressed, the stem 12 is pressed against the stem contact portion 107. When the stem 12 is pressed by pressing the aerosol container 10, the contents of the aerosol container 10 are filled in the metering tank 14.

  Further, when the aerosol container 10 is pressed, the pressing force is measured by the load cell 33, and the second controller 9b evaluates the quality of the aerosol container 10 based on the measurement result.

  FIG. 15 is a flowchart showing the control of the second controller 9b. First, the second controller 9b receives the measurement result of the pressing force from the load cell 33 (step S3041). Next, the second controller 9b displays the measurement result on the display unit 92 (step S3042). Subsequently, the second controller 9b determines whether the aerosol container 10 is a non-defective product or a defective product based on the measurement result (step S3043).

  FIG. 16 is a graph showing an example of the measurement result of the pressing force. This graph shows the relationship between time and pressing force, the horizontal axis shows the time since the actuator 30 started to operate, and the vertical axis shows the pressing force measured by the load cell 33. .

  The determination as to whether the aerosol container 10 is a good product or a defective product can be made, for example, as follows. First, as shown in FIG. 16, an allowable maximum pressing force and an allowable return time are set in advance. The return time is a time from when the pressing force acting on the aerosol container 10 starts to decrease due to the piston rod 32 being pulled into the actuator 30 until the pressing force finally stops acting on the aerosol container 10. If the maximum pressing force and the return time in the measurement result are both within the range of the allowable maximum pressing force and the allowable return time, it is determined that the aerosol container 10 is a non-defective product, and at least one is an allowable value. If it is out of the range, it is determined that the product is defective.

  In FIG. 16, a solid line A indicates a graph when a good aerosol container 10 is pressed. Moreover, the dotted line B and the dotted line C have shown the graph when pressing the defective aerosol container 10. FIG. As shown by the solid line A, in the non-defective aerosol container 10, when the actuator 30 is operated, the pressing force of the aerosol container 10 increases as time passes, and reaches the maximum pressing force. Thereafter, when the piston rod 32 is pulled into the actuator 30, the pressing force of the aerosol container 10 decreases, and finally the pressing force does not act. The maximum pressing force and the return time of the solid line A are within the range of the allowable maximum pressing force and the allowable return time. As indicated by the dotted line B, in the defective aerosol container 10, the pressing force of the aerosol container 10 continues to increase and may be outside the range of the maximum pressing force. This is a case where the stem 12 of the aerosol container 10 is abnormal and the aerosol container 10 cannot be pressed smoothly. In addition, as indicated by the dotted line C, in the defective aerosol container 10, the pressing force of the aerosol container 10 is rapidly decreased, and the return time may be out of the allowable return time range. This is a case where the stem 12 of the aerosol container 10 is not smoothly returned to its original state due to being caught.

  The second controller 9b determines whether or not the aerosol container 10 is a non-defective product, and then stores the determination result in the memory 91 (step S3044). Specifically, the distinction as to whether the aerosol container 10 is a non-defective product and the number of the bucket holder 23 that holds the aerosol container 10 are stored as a set in the memory 91.

  The piston rod 32 protrudes and presses the aerosol container 10 and is then drawn into the actuator 30 again. Thereby, the press of the aerosol container 10 and the stem 12 is released, and the stem 12 returns to the original state.

  Thereafter, as shown in FIG. 13, the first controller 9a operates the air cushion cylinder 40 again (step S305). As a result, the piston rod 41 is pulled into the air cushion cylinder 40, the pressure of the slide guide 234 is released, and the bucket holder 23 holds the bucket 100 again.

  In this way, quality evaluation is performed via the load cell 33.

  Next, weighing in the first weighing sensor 70a will be described. Here, a part of the description of the same steps as those described above will be omitted. First, in step S301 described above, when the first controller 9a rotates the sprocket 21 and the bucket holder 23 moves in the transport direction A, the bucket holder 23 is disposed below the air cushion cylinder 40. Further, the bucket 100 and the aerosol container 10 are disposed above the first weighing sensor 70a. The aerosol container 10 conveyed to the area of the first weighing sensor 70a has already been subjected to quality evaluation by the load cell 33.

  Next, in step S302 described above, when the piston rod 41 protrudes downward by operating the air cushion cylinder 40 by the first controller 9a, the slide guide 234 of the bucket holder 23 is pressed, and the pair of opening / closing plates 231 is pressed. 231 opens to the left and right. And if the bucket 100 currently hold | maintained at the bucket holder 23 is released, this bucket 100 will be mounted on the 1st measurement sensor 70a.

  At this time, the weight of the bucket 100 holding the aerosol container 10 is measured by the first weighing sensor 70a, and the second controller 9b processes the measurement result. The second controller 9b receives the measurement result from the first weighing sensor 70a and displays it on the display unit 92. Further, the second controller 9 b stores the measurement result in the memory 91.

  Thereafter, in step S305 described above, the first controller 9a operates the air cushion cylinder 40, whereby the bucket holder 23 holds the bucket 100 again.

  In this way, the weighing by the first weighing sensor 70a is performed.

  Next, quality evaluation through the laser sensor 50 will be described. Here, a part of the description of the same steps as those described above will be omitted.

  First, when the bucket holder 23 is conveyed in step S301 described above, the bucket holder 23 is disposed below the air cushion cylinder 40. Further, the bucket 100 and the aerosol container 10 are disposed below the pressing actuator 30b. The aerosol container 10 conveyed below the pressing actuator 30b for quality evaluation via the laser sensor 50 has already been subjected to quality evaluation via the load cell 33 and measurement using the first measurement sensor 70a. Is.

  Next, when the bucket 100 is released from the bucket holder 23 in step S302 described above, the bucket 100 is placed on the support member 42.

  Subsequently, when the actuator 30 is operated in step S303 described above, the aerosol pressing body 36 presses the bottom of the aerosol container 10 in the pressing actuator 30b. By pressing the aerosol container 10, the stem 12 is pressed by the stem contact portion 107, and the contents of the aerosol container 10 are ejected from the stem 12. The ejected contents pass through the nozzle portion 106 of the bucket 100 and are ejected to the outside, and pass through the laser region of the laser sensor 50. The laser sensor 50 measures the state of the ejected contents.

  Next, a method for measuring the state of the contents of the aerosol container 10 ejected by the laser sensor 50 will be described. FIG. 17 is a top view of the laser sensor 50. When the content 18 in the aerosol container 10 is ejected in a state where the laser projected from the light projecting device 51 is received by the light receiving device 52, the content 18 passes through the laser region 55 as time passes. I will do it. In the process in which the content 18 passes through the laser region 55, the region (area) where the content 18 exists is detected by the laser sensor 50 at regular time intervals. For example, in the laser region 55 at time T1, when the contents 18 exist in the region (area) X1, the laser sensor 50 detects this area X1. Thereafter, at times T2, T3,..., The areas X2, X3,. Thus, the ejection state of the content 18 is measured by detecting the area (area) where the content 18 exists at each time.

  When the laser sensor 50 measures the ejection state, the second controller 9b evaluates the quality of the aerosol container 10 based on the measurement result. First, the second controller 9b receives the measurement result from the laser sensor 50 in step S3041 described above, and displays the measurement result on the display unit 92 in step S3042. In step S3043, the second controller 9b determines whether the aerosol container 10 is a good product or a defective product based on the measurement result.

  FIG. 18 is a graph showing an example of the measurement result of the ejection state. This graph shows the relationship between time and area, the horizontal axis shows the time since the actuator 30 started to operate, and the vertical axis shows the area where the contents of the aerosol container 10 are present in the laser region. Is shown.

  The determination as to whether the aerosol container 10 is a good product or a defective product can be made, for example, as follows. First, as shown in FIG. 18, an allowable maximum area, an allowable ejection time, and an allowable leakage value are set in advance. The ejection time is the time during which the contents of the aerosol container 10 are ejected. The leakage value is a slight leakage after the contents are ejected. If the maximum area, the ejection time, and the leakage value in the measurement results are all within the allowable maximum area, the allowable ejection time, and the allowable leakage value, it is determined that the aerosol container 10 is a non-defective product. On the other hand, if at least one of the above values is outside the allowable value range, it is determined that the aerosol container 10 is a defective product.

  In FIG. 18, a solid line A shows a graph when a good aerosol container 10 is pressed. Moreover, the dotted line B and the dotted line C have shown the graph when pressing the defective aerosol container 10. FIG. As shown by the solid line A, in the good aerosol container 10, the region (area) where the contents are present in the laser region increases with the passage of time, and reaches the maximum area. Thereafter, since the contents existing in the laser region are decreased, the area is decreased and finally the content is not present in the laser region. The maximum area and ejection time of the solid line A are within the allowable maximum area and allowable ejection time. On the other hand, as indicated by the dotted line B, in the defective aerosol container 10, the region (area) where the contents are present does not decrease, and the ejection time may be outside the allowable ejection time range. This is a case where the stem 12 of the aerosol container 10 has an abnormality and the contents continue to be ejected without being released while the stem 12 is pressed. Further, as indicated by the dotted line C, in the defective aerosol container 10, the contents may not be ejected, or the contents may leak and the leakage value may be outside the allowable leakage value range. This is also the case when there is an abnormality in the stem 12.

  After determining whether or not the aerosol container 10 is a non-defective product, the second controller 9b stores the determination result in the memory 91 in step S3044 described above. Specifically, the distinction as to whether the aerosol container 10 is a non-defective product and the number of the bucket holder 23 that holds the aerosol container 10 are stored as a set in the memory 91.

  The piston rod 32 of the actuator 30 protrudes and presses the aerosol container 10 and then is drawn into the actuator 30 again. Thereby, the press of the aerosol container 10 and the stem 12 is released, and the stem 12 returns to the original state.

  Thereafter, in step S305, the first controller 9a operates the air cushion cylinder 40 again, whereby the bucket holder 23 holds the bucket 100.

  In this way, quality evaluation through the laser sensor 50 is performed.

  Next, quality evaluation through the microphone 60 will be described. Here, a part of the description of the same steps as those described above will be omitted.

  First, when the bucket holder 23 is conveyed in step S301 described above, the bucket holder 23 is disposed below the air cushion cylinder 40. Further, the bucket 100 and the aerosol container 10 are disposed below the pressing actuator 30b. The aerosol container 10 conveyed below the pressing actuator 30b for quality evaluation via the microphone 60 is subjected to quality evaluation via the load cell 33, measurement by the first measurement sensor 70a, and via the laser sensor 50. The quality evaluation has already been performed.

  Next, when the bucket 100 is released from the bucket holder 23 in step S302 described above, the bucket 100 is placed on the support member 42.

  Subsequently, when the actuator 30 is operated in step S303 described above, the aerosol pressing body 36 presses the bottom of the aerosol container 10 in the pressing actuator 30b. By pressing the aerosol container 10, the stem 12 is pressed by the stem contact portion 107, and the contents of the aerosol container 10 are ejected from the stem 12. When the contents are ejected, the ejection sound is measured by the microphone 60.

  When the microphone 60 measures the ejection sound, the second controller 9b evaluates the quality of the aerosol container 10 based on the measurement result. First, the second controller 9b receives the measurement result from the microphone 60 in step S3041 described above, and displays the measurement result on the display unit 92 in step S3042. In step S3043, the second controller 9b determines whether the aerosol container 10 is a good product or a defective product based on the measurement result.

  FIG. 19 is a graph showing an example of the measurement result of the ejection sound. This graph shows the relationship between time and the ejection volume, the horizontal axis shows the time since the actuator 30 started to operate, and the vertical axis shows the volume of the ejection sound collected by the microphone 60. Show.

  The determination as to whether the aerosol container 10 is a good product or a defective product can be made, for example, as follows. First, as shown in FIG. 19, an allowable maximum ejection volume and an allowable ejection time are set in advance. If the maximum ejection volume and the ejection time in the measurement result are both within the allowable maximum ejection volume and the allowable ejection time, it is determined that the aerosol container 10 is a non-defective product. On the other hand, if at least one of the above values is outside the allowable range, it is determined that the aerosol container 10 is a defective product.

  In FIG. 19, a solid line A shows a graph of the ejection volume of a good aerosol container 10. Moreover, the dotted line B and the dotted line C have shown the graph of the ejection volume of the defective aerosol container 10. FIG. As shown by the solid line A, in the good aerosol container 10, the ejection volume increases with time and reaches the maximum ejection volume. After that, the volume of eruption decreases. The maximum ejection volume and ejection time indicated by the solid line A are within the range of the allowable maximum ejection volume and the allowable ejection time. On the other hand, as indicated by the dotted line B, in the defective aerosol container 10, the ejection volume does not decrease, and the ejection time may be outside the allowable ejection time range. This is a case where the stem 12 of the aerosol container 10 has an abnormality and the contents continue to be ejected without being released while the stem 12 is pressed. Further, as indicated by a dotted line C, in the defective aerosol container 10, the maximum ejection volume may be outside the range of the allowable maximum ejection volume. This is a case where the contents are not ejected smoothly.

  After determining whether or not the aerosol container 10 is a non-defective product, the second controller 9b stores the determination result in the memory 91 in step S3044 described above. Specifically, the distinction as to whether the aerosol container 10 is a non-defective product and the number of the bucket holder 23 that holds the aerosol container 10 are stored as a set in the memory 91.

  The piston rod 32 of the actuator 30 protrudes and presses the aerosol container 10 and then is drawn into the actuator 30 again. Thereby, the press of the aerosol container 10 and the stem 12 is released, and the stem 12 returns to the original state.

  Thereafter, in step S305, the first controller 9a operates the air cushion cylinder 40 again, whereby the bucket holder 23 holds the bucket 100.

  In this way, quality evaluation through the microphone 60 is performed.

  Next, weighing by the second weighing sensor 70b will be described. Here, a part of the description of the same steps as those described above will be omitted. First, in step S301 described above, when the first controller 9a rotates the sprocket 21 and the bucket holder 23 moves in the transport direction A, the bucket holder 23 is disposed below the air cushion cylinder 40. Further, the bucket 100 and the aerosol container 10 are disposed above the second weighing sensor 70b. The aerosol container 10 transported to the area of the second weighing sensor 70b is subjected to quality evaluation via the load cell 33, weighing by the first weighing sensor 70a, quality evaluation via the laser sensor 50, and quality via the microphone 60. Evaluation has already been performed.

  Next, in step S302 described above, when the first controller 9a operates the air cushion cylinder 40 and the piston rod 41 protrudes downward, the slide guide 234 of the bucket holder 23 is pressed, and the pair of opening / closing plates 231 is pressed. 231 opens to the left and right. And if the bucket 100 currently hold | maintained at the bucket holder 23 is released, this bucket 100 will be mounted on the 2nd measurement sensor 70b.

  At this time, the weight of the bucket 100 holding the aerosol container 10 is measured by the second weighing sensor 70b, and the second controller 9b measures the measurement result of the first weighing sensor 70a and the measurement result of the second weighing sensor 70b. Based on the above, the quality of the aerosol container 10 is evaluated. Specifically, the amount of decrease in the contents of the aerosol container 10 is calculated based on the measurement results of the first measurement sensor 70a and the second measurement sensor 70b, and whether the aerosol container 10 is a non-defective product based on the calculation result. Determine if it is defective. For example, if the amount of decrease in content is within a preset allowable range, it is determined that the aerosol container 10 is a non-defective product. On the other hand, if the amount of decrease in content is outside the allowable range, it is determined that the content is ejected excessively or insufficiently and that the aerosol container 10 is defective. If the contents of the aerosol container 10 are appropriately ejected in the quality evaluation via the laser sensor 50 and the microphone 60, the amount of decrease in the contents falls within an appropriate range. The second controller 9b stores the determination result in the memory 91 after determining whether the aerosol container 10 is a non-defective product. Specifically, the distinction as to whether the aerosol container 10 is a non-defective product and the number of the bucket holder 23 that holds the aerosol container 10 are stored as a set in the memory 91.

  Thereafter, in step S305 described above, the first controller 9a operates the air cushion cylinder 40, whereby the bucket holder 23 holds the bucket 100 again.

  In this way, the weighing by the second weighing sensor 70b is performed.

  Next, the operation of the printer 80 will be described. First, when the bucket holder 23 is moved in the transport direction A by the above-described step S301, the bucket 100 and the aerosol container 10 are disposed below the printer 80. The aerosol container 10 transported to the area of the printer 80 has already been subjected to quality evaluation by the load cell 33, the laser sensor 50, the microphone 60, and the weighing sensor 70.

  Next, when the first controller 9 a operates the printer 80, the printer 80 performs printing on the aerosol container 10 as a good product or a defective product. Whether the aerosol container 10 is a non-defective product is determined based on information stored in the memory 91. This information is information stored in the memory 91 based on each quality evaluation described above. For example, if the aerosol container 10 is determined to be defective by any of the quality evaluation via the load cell 33, the laser sensor 50, the microphone 60, and the weighing sensor 70, the printer 80 is not installed in the aerosol container 10. Print good products. On the other hand, when each quality evaluation is a non-defective product, the non-defective product is printed.

  Then, the quality evaluation of the aerosol container 10 is sequentially performed by repeating each step described above.

  According to the quality evaluation apparatus and the quality evaluation method having such a configuration, the aerosol container 10 is pressed by the actuator 30, the pressing force is measured by the load cell 33, and the quality of the aerosol container 10 is evaluated based on the measurement result. Therefore, it is possible to evaluate the quality of the aerosol container quickly and accurately without relying on manual work as in the prior art.

  Moreover, since the state of the contents of the aerosol container 10 is measured by the laser sensor 50 and the quality of the aerosol container 10 is evaluated based on the measurement result, the quality can be evaluated more accurately.

  Moreover, since quality evaluation is performed based on the ejection sound measured by the microphone 60, the quality of the aerosol container 10 can be evaluated more accurately.

  Moreover, since the quality of the aerosol container 10 is evaluated based on the measurement result by the measurement sensor 70, more accurate quality evaluation can be performed.

  As mentioned above, although one Embodiment of this invention was described, the specific aspect of this invention is not limited to the said embodiment.

  For example, the aerosol container 10 is not limited to the above embodiment, and other known aerosol containers can be used.

  Further, the order of quality evaluation is not necessarily limited to the order described above. For example, quality evaluation via the microphone 60 may be performed before quality evaluation via the laser sensor 50.

  Moreover, not all of the above-described quality evaluations are necessarily required, and some of them can be omitted. For example, quality evaluation via the microphone 60 and the weighing sensor 70 can be omitted.

  Further, in this embodiment, the sprocket 21 is rotated and the bucket holder 23 is transported by the rotational drive of a drive motor (not shown). However, if the bucket holder 23 can be transported in the transport direction, this configuration is adopted. Not particularly limited. For example, the structure which conveys the bucket holder 23 using a cylinder member may be sufficient. This configuration includes a plurality of vertical cylinders in which the piston rod protrudes in the vertical direction and horizontal cylinders in which the piston rod protrudes in the horizontal direction. According to this configuration, first, the piston rod of the vertical cylinder protrudes vertically upward, so that the bucket holder 23 is moved in the vertical direction so that it can move in the horizontal direction. Next, in this state, when the piston rod of the horizontal cylinder protrudes in the horizontal direction, the bucket holder 23 is moved in the horizontal direction (conveying direction). Then, the bucket holder 23 is moved vertically downward by returning the piston rod of the vertical cylinder to the original state. In this way, the bucket holder 23 is sequentially transported in the transport direction.

  In this embodiment, the controller is divided into the first controller 9a and the second controller 9b. However, the controller is not necessarily divided as long as the operation of the quality evaluation apparatus 1 can be controlled.
