When the height of the inspected can 1 measured as described above is normal, the X-ray generator 11 shown in FIG.
When the X-ray X RAY is emitted from the device, the canned state of the inspected can 1 is inspected. Since the winding state inspection method at this time is the same as the above-described conventional winding state inspection method, the details thereof will be omitted. At this time, the winding state is inspected in the winding portion 2 of the can 1 to be inspected.
This is the part in contact with the fixed roller 15. As described above, in the can winding state inspection device of the present embodiment, the winding can is clamped for the inspected can 1 held at the inspection position by the fixed roller 15, the first movable roller 24 1 and the second movable roller 24 2 . In order to perform the condition inspection, when inspecting the winding state of the inspected can, which is smaller than the inspected can 1 and shown by the one-dot chain line in FIG. Also in the case of inspecting the winding state of the inspected can, the winding portion for performing the winding state inspection can be the winding portion of the portion in contact with the fixed roller 15, so that the X-ray generator 11 Also, there is no need to change the position of the X-ray camera 12. Therefore, there is an advantage that cans of any size can be accommodated without changing the positions of the X-ray generator 11 and the X-ray camera 12.

When the canned state of the inspected can 1 inspected as described above is normal, the quality of the canned state cannot be judged at only one place. When you inspect three places every 120 °,
The fixed roller motor 28 shown in FIG. 2 rotates the fixed roller 15 through the belt 27 by a predetermined number of rotations, whereby the inspected can 1 is rotated by 120 °, and then the above-described operation is performed. Repeated. At this time, since the inspected can 1 is held in the inspection position by the fixed roller 15, the first movable roller 24 1 and the second movable roller 24 2 , the state in which the inspected can 1 is held in the inspection position Can be rotated by 120 °.

After measuring the height of the can at the position of the winding portion where the winding state inspection is performed, the winding state inspection by X-ray can be continuously performed without moving the can to another place. In addition, it is possible to continuously measure the height of several cans and inspect the winding condition without moving the can from the inspection position, which simplifies the mechanism of the entire can inspecting device. The inspection work can be simplified by shortening the measurement time.
