The operation of the product inspection apparatus A thus configured will be described. First, when the product 2 is supplied to the alignment supply unit 5 and the product inspection device A is started, the suction unit 15 operates under the control of the control unit, and then the product 2 sequentially aligned in the supply port 5a of the alignment supply unit 5 Is sucked by the force from the suction port 1b opened in the holding groove 1a, and the product 2 supplied from the supply port 5a is sucked into the holding groove 1a as it is,
The first surface 2a and the second surface 2b of the product 2 shown in FIG. 2 are fitted in the holding groove 1a, and the product 2 is held in the holding groove 1a. In this way, the product 2 is sequentially supplied from the supply port 5a of the alignment supply unit 5 toward the holding groove 1a of the rotating body 1. FIG.
Is an enlarged view of the supply port 5a, as shown in FIG.
The supply port 5a is provided with a groove 5b.
By the operation described above, the products 2 are sequentially aligned in the grooves 5b. The method of aligning the products 2 of the aligning supply unit 5 will not be described in detail here. In the first embodiment, the cross section of the groove 5b of the supply port 5a is V-shaped, and the width thereof is such that the products 2 are arranged in one line. By forming the groove 5b of the supply port 5a in a V-shape in this way, it becomes easy to orderly arrange the products 2 as shown in FIG. 3, and the product 2 placed on the groove 5b of the supply port 5a is The product 2 and the holding groove 1a can be easily fitted by being slid toward the holding groove 1a having the shape of the U-shaped groove.

Here, as shown in FIG. 2, a sensor 4 is provided so that a product 2 moving on a line 10 connecting the supply port 5a and the holding groove 1a can be searched. By providing the sensor 4 in this way, the product 2 can be inserted into the holding groove 1a from the supply port 5a.
Is supplied, the control unit detects this, and notifies the control unit that the product 2 has been supplied from the supply port 5a. Then, the control unit sends a signal to the motor 7 and the first camera 3a and the second camera 3b. The first camera 3a and the second camera 3b notified from the control unit that the product 2 has been supplied, the product 2 has the holding groove 1a.
Before fitting, the outer surface of the product 2 is imaged. In particular,
The first camera 3a captures an image of the first surface 2a of the product 2 shown in FIG. 2, and the second camera 3b captures an image of the second surface 2b. The captured video is input to the inspection unit. In the first embodiment, the first camera 2a and the second camera 3b are used to image the first surface 2a and the second surface 2b of the product 2, but other than this, although not specifically shown, for example, It is also conceivable to take an image of the first surface 2a and the second surface 2b of the product 2 together with one camera from directly above.

Next, when the control unit notifies that the product 2 has been supplied from the supply port 5a, the motor 7 is driven to rotate the rotating body 1 by a predetermined amount. Specifically, by rotating the rotating body 1 so that the holding groove 1a on the line 10 moves by one, the product 2 is not newly held,
That is, the motor 7 rotates the rotating body 1 so that the empty holding groove 1a is on the line 10. When the empty holding groove 1a that does not hold the product 2 comes on the line 10, the above-described product supply operation is performed. By repeating this operation, the product 2 is sequentially sucked from the supply port 5a into the holding groove 1a, and in the process, the appearance of the first surface 2a and the second surface 2b of the product 2 is continuously imaged. Further, the rotating body 1 may rotate continuously or may rotate intermittently.

To briefly explain an example of this product collection method, when the holding groove 1a holding the product 2 determined to be acceptable by the control unit reaches the acceptable area G, Here, compressed air is injected toward the holding groove 1a by using a pressurizing device (not shown), and the passed product 2 is blown off from the holding groove 1a, and this is blown off from the non-defective product collection unit 1
No. 6 is considered. For the product 2 which failed, the holding groove 1 for holding the product 2
The product which failed to emit compressed air even when it reached the acceptance area G, and at the same time devised the way of providing the suction path 1c connected to the suction port 1b as shown in FIGS. When the product 2 reaches the reject area B, the product 2 is naturally dropped and collected by the defective product collection unit 17. FIG. 5 is a cross-sectional view taken along the line SS in FIG. As an example of a method of providing the suction path 1c connected to the suction port 1b, it is conceivable that a suction disk 20 as shown in FIG. Although the suction disk 20 is in close contact with the rotating body 1, the suction disk 20 itself remains fixed and does not rotate. The suction groove 1d is provided on the side that is in close contact with the rotating body 1, as shown in the drawing. That is, the suction groove 1d is not provided in the portion of the rotating body 1 that is in close contact with the reject area B. Then, one end of the suction groove 1d is connected to the suction path 1c. With this configuration, when the holding groove 1a reaches the lowermost end, one end of the suction path 1c provided in the rotating body 1 overlaps the suction groove 1d, and suction is started from the suction port 1b through the suction path 1c. When the rotation continues, the holding groove 1a eventually reaches the rejected area B, but the suction port 1b of the holding groove 1a reaching this portion.
Since there is no suction groove 1d connected to the suction path 1c leading to the above, the holding groove 1a reaching this portion cannot suction the product 2. That is, since the suction force is lost in a state where the opening of the holding groove 1a faces downward, the product 2 held so far falls naturally and is collected by the defective product collecting part 17.
