The illustrated embodiment will be described below. A is a fiberscope formed by inserting an optical fiber bundle 2 into a protective tube 1 and rotatably fitting a cannula 3 to its protruding tip side; b is a fiberscope that supports this fiberscope a and extends it in its length direction; It is a reciprocating drive mechanism that reciprocates. This reciprocating drive mechanism b has a guide rail 4 at the top.
The tip of the piston rod 7 of a pneumatic or hydraulic cylinder 6 installed vertically on the machine stand 5 is connected to an arm 8 whose base end is fitted to the guide rail 4 so as to be movable up and down. The fiberscope a is supported and suspended from the cylinder 6, and the fiberscope a can be reciprocated up and down by the operation of the cylinder 6. The fiberscope a has a protective tube 1 held between a mounting piece 9 at the tip of an arm 8 and a holding plate 10, and a connecting tube rotatably fitted to the lower end step 11 of the protective tube 1. A connecting tube 13 fixed to the upper end of the mantle 3 is screwed into the lower end opening of the mantle 3, and the mantle 3 is inserted into the hole 1 of the receiving plate 14 extending from the machine base 5.
5 is inserted. Reference numeral c denotes a prism which is provided to open and close with respect to the condensing surface at the tip of the objective of the fiberscope a.
It is rotatably supported by a spring 18 and is normally biased by a spring 18 to take an open position (solid line in FIG. 1, dashed line in FIG. 2). Reference numeral 19 denotes an annular prism opening/closing seat fitted in the sleeve 3 so as to be vertically slidable, and this seat 19 and the tip of the support frame 16 are connected by a connecting rod 20. Note that, as described above, when the prism c is in the open position due to the bias of the spring 18, the seat 19 is
It is in such a relationship that it comes into contact with a catch seat 21 which is fixedly attached (Fig. 1). d is a prism rotation drive mechanism that rotates the sleeve 3 around the optical fiber bundle 2 in order to rotate the prism c around the objective tip of the fiberscope a. This prism rotation drive mechanism d includes a gear 2 attached to the output shaft of a prism rotation motor 22 with a reduction gear mounted on a presser plate 10 at the tip of an arm 8.
3 and a gear 24 attached to the connecting tube 12 are connected by a chain 25, and the prism c can be horizontally rotated together with the sleeve 3 by the operation of the motor 22. Inspection of the inner surface of a can using this inspection apparatus having such a configuration is performed as follows. At the final stage of a series of automatic recycling processing steps or automatic new can manufacturing steps, the drum e is transported by a required transport device f, and the entrance/exit 27 of the top plate 26 is aligned with the objective tip of the fiberscope a of this inspection device. It will automatically stop when Upon this stop, the fiberscope a is lowered by the reciprocating drive mechanism b, and the objective tip enters the drum can e through the entrance/exit port 27, and as a first step, at the upper position h inside the can, the light converging surface is placed in front of the drum can e, i.e. The reflected light from the inner surface of the lower half of the can, including the bottom surface of the can, is directly condensed, and an image of the inside of the can is transmitted by focusing on the cross section of the fiber bundle 2, and the output image is transmitted to the base end of the eyepiece of the fiberscope a. Observe. In the second step, the fiberscope a is further lowered, the prism opening/closing seat 19 comes into contact with the periphery of the hole 15 in the base plate 14, and the fiberscope a is lowered a little further until the objective tip reaches the lower position l inside the can. When the prism c rotates against the biasing force of the spring 18, it changes from the open position (dashed line in Figure 2) to the closed position (solid line in the same figure), and the light converging surface at the tip of the objective is placed behind it, that is, on the top plate. The reflected light from the inner surface of the upper half of the can, including the inner surface of 26, is collected through prism c, and as described above,
An in-can image formed on a cross section of the optical fiber bundle 2 is transmitted, and the output image is observed at the base end of the eyepiece. In this case, the viewing angle of the prism c can be made wider by rotating the prism c via the sleeve 3 by the prism rotation drive mechanism d. The above observation at the proximal end of the eyepiece is actually
A television or video camera is connected to the base end, and images inside the can are projected on the television screen. When rust or foreign matter is detected in the drum can e by observation, the drum can is manually or automatically selectively transported to another transport device. Note that the fiberscope a is pulled out by raising the fiberscope a by the reciprocating drive mechanism b. When it is separated, the force of the spring 18 automatically rotates it back to the original open position. Therefore, by adjusting the height of this receiving plate 14, the height at which the prism c opens and closes can be arbitrarily adjusted.

The can inner surface inspection apparatus of the present invention has the following effects. By extending and retracting the piston rod of the pneumatic or hydraulic cylinder, the fiberscope, together with the prism at its lower end, can be automatically inserted and removed through the opening provided in the top of the can. The fiberscope is inserted into the can through the entrance/exit with the prism at the tip of the objective in the open position, and the reflected light from the front (image inside the can) is directly focused on the focusing surface. In addition, by placing the prism in the closed position at the required insertion depth and horizontally rotating it via the cannula using the prism rotation motor, the reflected light (image inside the can) from the opposite direction can be indirectly directed to the light converging surface. While converging the light to can be observed through the eyepiece proximal end of the fiberscope. The support frame of the prism is biased by a spring and rotatably supported at the lower end of the cannula, and is connected via a connecting rod to a prism opening/closing seat fitted around the outer circumference of the cannula. Therefore, by bringing this prism opening/closing seat into contact with, for example, a receiving plate installed at an arbitrary height on the outside of the can, and releasing the contact, the prism can be opened and closed by moving the top and bottom of the fiberscope. This can be done automatically at any height according to the movement.
