TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap appearance inspection device used for beverage bottle cans and the like, which has a top wall and a cylindrical skirt wall hanging down from the periphery of the top wall, particularly a cap that requires inspection of an outer surface such as an aluminum cap. .
[0002]
[Prior art]
Conventionally, a cap having a top wall and a cylindrical skirt wall hanging down from the periphery of the top wall as shown in FIG. 8 has been widely used. The cap 100 includes a main body 101 and a sealing gasket 102 attached to the inner top surface of the main body. In the inspection of the cap, it is preferable to inspect the top surface 103, the outer surface 104, the inner top surface 105, and the inner surface 106, such as printing performed on these surfaces and sealing packing provided on the inner top surface 105. A method has been used in which an image of the displacement and dirt is captured by a camera and processed by a computer to determine the difference between a good product and a defective product.
[0003]
As the appearance inspection of the cap, for example, an apparatus as shown in FIG. 9 is used. In this apparatus 200, first, a camera 230 is provided above a first conveyer 210 which conveys the cap 100 while suctioning and fixing the inner surface side thereof. The image of the outer top surface 103 is taken in, and a difference from a good product is determined to detect a defective product. Then, after that, the first conveyor 210 is provided in a direction opposite to the first conveyor 210, and the second conveyor 220 that conveys the cap 100 fixed to the lower side of the conveyor 220 by sucking the top surface 103 side of the cap. While moving 100 as shown by the arrow 72, the camera 240 provided below the second conveyor 220 is used to capture the images of the inner surfaces 105 and 106 of the cap, and to judge pass / fail as described above. I do.
[0004]
However, the above-described apparatus has a problem that the inspection in the direction parallel to the conveyor surface, that is, the inspection of the side surface 104 of the cap cannot be performed. In particular, in recent years, the outer surface 104, such as an aluminum cap, on which printing has been performed has often been used, so that the necessity of inspecting the side surface has increased.
[0005]
For this reason, using a rotating turret as disclosed in JP-A-59-182124 (Patent Document 1) and JP-A-9-240833 (Patent Document 2), using an apparatus shown in FIG. Inspection of the outer surface (top surface and side surface) and the inner surface (inner top surface and inner surface) of the cap are performed.
[0006]
The apparatus 300 intermittently controls the rotation of a rotating turret 310 having a plurality of notches 312 in a direction indicated by an arrow 74 and performs a predetermined inspection at the determined position. That is, as shown in FIG. 10, when the cap 100 is introduced into the notch 312, first, the top surface 103 of the cap is inspected by the top surface inspection camera 320. When the turret rotates and moves to the next position, the cap fitted in the notch is rotated by itself as indicated by an arrow 75, and the entire periphery of the side surface 104 is inspected by the side inspection camera 330.
[0007]
Then, in order to inspect the inner surface sides 105 and 106 of the cap, the cap 100 is once ejected from the turret as shown by the arrow 77, moved along the transport guide, turned upside down as shown by the arrow 78, and again. The rotating turret 310 is introduced. Thereafter, the inner surfaces 105 and 106 of the cap are inspected by the inner surface inspection camera 340 in the same manner as described above.

[0009]
[Problems to be solved by the invention]
However, in the above-described apparatus, it is necessary to discharge the cap 100 to the outside of the rotating turret 310 whose rotation is controlled by intermittent feeding in order to invert the cap 100, so that the index management of the cap cannot be performed. There is. Therefore, when inspecting the cap with a plurality of cameras, the top surface inspection camera 320 or the side inspection camera 330 found out before the cap was ejected out of the rotating turret 310 for reversal and index management could not be performed. The defective product 10x is removed from the turret 310 as shown by the arrow 76, and then the defective product 100x found by the inner surface inspection camera 340 after being introduced into the rotating turret again is removed independently (arrow 80). Control device is required.

Accordingly, two mechanisms for removing defective products are provided at two locations, and two mechanisms for introducing the cap 100 in synchronization with the rotating turret 310 are required, which has been a problem in the manufacturing cost of the apparatus.
[0012]
Furthermore, when the inspection is performed, there is a problem in that the caps pass through the inside of the transport guide and damage the outer surfaces 103 and 104 of the caps determined to be non-defective by the inspection performed before the reversal. Further, there may be a case where the cap is clogged in the transport guide, and the inspection is interrupted.
[0013]
Therefore, the technical problem to be solved by the present invention is to be able to inspect the top surface, side surface and inner surface of the cap with an inexpensive and simple configuration, and to solve the problem of scratches and clogging during the inspection. It is an object of the present invention to provide an appearance inspection device for a cap which can be used.
