Next, the operation of the embodiment will be described.

When inspecting the bottle B, for example, a 1.8 liter bottle for sake, the handle 52 of the interval adjusting means 50 is operated according to the diameter of the bottle B to position the movable stages 36 and 37. Is adjusted so that the bin B can be held by the attachments 41, 42 of the side gripping chain conveyor 40.

First, the bin B to be inspected is transferred to the first conveyor 1
When sequentially supplied in the state of being erected from 1, the in-feed screw 38 arranges the supplied bins B at a predetermined pitch p, and the guide attachment 42 of the second side grip chain conveyor 44 contacts the bin B and grips it. It is conveyed to the roof inspection position P1. At the top inspection position P1, the presence or absence of a defect in the top of the bottle B is detected by the mouth top inspection camera 23.

Next, the bin B has a guide attachment 42 of the second side gripping chain conveyor 44 and a top inspection position P.
After being moved by being sandwiched by the guide plate 75 provided on the movable stage 36 of No. 1, it comes into contact with the guide attachment 41 of the first side holding chain conveyor 43, and the attachment 41 and the guide attachment 42 of the second side holding chain conveyor 44 It is gripped and transferred to the bottle bottom inspection position P2, where it is illuminated from the bottle bottom by the illuminating device 24, and the bottle bottom inspection camera 25 detects whether or not foreign matter is attached to the inner bottom of the bottle. . In this bottle bottom inspection, the bin B is gripped by the guide attachments 41 and 42 of the side gripping chain conveyor 40, and the lighting device 24.
In addition to being floated from above, the neck guide 35 is hung so that the centering is surely performed and the bottle bottom can be accurately inspected.

After the inspection, the bin B is re-mounted on the second conveyor 12 and conveyed to both inspection positions P1 and P2.
Then, the bin B that has been determined to be defective is rejected by the reject lever means 81.
Then, it is paid out to the turntable 80.

The payout by the reject lever means 81 can be easily separated from the non-defective bins B because the bins B are conveyed side by side at a predetermined pitch p.

When inspecting different kinds of bins B, the handle 52 of the interval adjusting means 50 described above is operated to hold the bins B by the attachments 41 and 42 of the side grip chain conveyor 40. With adjustment
This can be easily done by adjusting the height of the cameras 23 and 25.
