Thereafter, by the same operation as described above, a plurality of fuel pellets 2 are intermittently moved in the direction of arrow A on the intermittent transfer conveyor 4 at predetermined intervals, and a predetermined number (in this embodiment, 5 fuel pellets) are moved on the intermittent transfer conveyor 4. When several fuel pellets 2 are lined up, the adsorber 40 descends, adsorbs each fuel pellet 2 on the intermittent transfer conveyor 4 at the same time, rises, moves in the direction of arrow B in FIG. A predetermined number of fuel pellets 2 are placed on the inspection table 3, and their adsorption is released, and the adsorber 40 rises and further moves in the direction of arrow C in FIG. 1 to wait on the intermittent transfer conveyor 4.

While the adsorber 40 transfers a predetermined number of fuel pellets 2 from the intermittent transfer conveyor 4 onto the end surface inspection table 3,
A predetermined number of fuel pellets 2 are conveyed from the carry-in conveyor 1 onto the intermittent transfer conveyor 4 in the same manner as described above.

At this time, the movable table 26 is in a state where the recess 33 is located approximately below the fuel pellet 2 placed on the end face inspection table 3, as shown in FIG. When placed, the cylinder mechanism 37 is extended and moves the movable table 26 up via the intermediate rod 31 and the parallel links 27, 28, 29, and 30 as shown in FIG. Then, each fuel pellet 2 on the end face inspection table 3 fits into the recess 33 and is lifted from the upper plate 19 of the end face inspection table 3.
In this state, the cylinder mechanism 39 continues to contract as shown in FIG. 5, and the sliding plate 23 moves a predetermined distance toward the rolling table 61 via the hanging protrusion 38 and stops, and then as shown in FIG. cylinder mechanism 37
is contracted and the intermediate rod 31, parallel link 27,
The moving table 26 is lowered via 28, 29, and 30.
As a result, the fuel pellets 2 placed on the moving table 26 are placed on the upper plate 19 of the end face inspection table 3.
Thereafter, the cylinder mechanism 39 is extended to return the sliding plate 23 and the moving table 26 to their original positions shown in FIG. 3.

After repeating the above operation and placing a predetermined number of fuel pellets 2 (in this example, 25 in 5 rows and 5 columns) on the end surface inspection table 3, the above operation is repeated once more and the end surface inspection table 3 is placed on the end surface inspection table 3 as shown in FIG. The rightmost upright fuel pellets 2 are shown in Figures 5, 6, and 10.
As shown in FIG. 11, it is placed on the cylinder support surface 48 of the cylinder holder 45, and the sliding plate 23 and moving table 26 are returned to their original positions.

Then, the rotational drive mechanism is actuated to rotate each roller 44 in the direction of the arrow shown in FIG. 11, and rotate each cylindrical body holder 45 by 90 degrees in the direction of the arrow shown in FIG.
As a result, the fuel pellet 2 on the cylindrical body holder 45 changes its posture from a standing state to a lying state. The fuel pellet 2 in this lying state rolls on the slope 52 and the slope plate 54 and rides on the recess 66 of the feeding piece 65 as shown in FIG.

When the fuel pellets 2 are placed on the recess 66, the motor 69 is activated and the worm 67 and worm wheel 6 are activated.
4. The feeding piece 65 rotates via the shaft 63 in the direction of the arrow shown in FIG. 12, lifts up the fuel pellet 2, and pushes out the fuel pellet 2 to the right in the figure while rotating. This extruded fuel pellet 2 continues to rotate and reaches the top of the feeding piece 65 at the 13th position.
As shown in Figure 14, cross over and proceed slightly. Then, the motor 69 rotates in the reverse direction, the feed piece 65 rotates slightly in the direction opposite to the direction of the arrow shown in FIG. Move over. The feeding piece 65 repeats this operation to sequentially feed each fuel pellet 2 on the recess 66 onto the inclined plate 70.

The fuel pellets 2 delivered onto the inclined plate 70 roll on this inclined plate 70 and change the cylindrical body attitude change mechanism 7.
The patient transfers onto the cylindrical support surface 47 of No. 1 in a lying state.
Then, the roller 44 at the bottom of the cylindrical body attitude changing mechanism 71 rotates, and the cylindrical body holder 45 rotates 90 degrees, causing the fuel pellet 2 to stand up and be supported by the cylindrical body support surface 48.

Then, from above the cylindrical body holder 45, the adsorber 4 is
0 descends, and this suction device 40 is moved to the columnar body holder 4.
It adsorbs each fuel pellet 2 on the end face inspection table 72, rises, moves a predetermined distance in the direction of arrow B in FIG.
is placed thereon, released from its suction, ascends, and returns above the cylindrical body attitude changing mechanism 71 to wait.

When each fuel pellet 2 is placed on the end face inspection table 72, the end face inspection table 72 picks up each of these fuel pellets 2.
are transferred on the end surface inspection table 72 in the direction of arrow B in FIG. Body posture change mechanism 4
3, the fuel pellets 2 are transferred to the cylindrical body support surface 48 of the cylindrical body posture changing mechanism 73 in an upright state. Then, the cylindrical body attitude changing mechanism 73 operates in the same manner as the cylindrical body attitude changing mechanism 43, and changes the attitude of the fuel pellet 2 to a lying state.
It is delivered onto the inclined plate 74.

The fuel pellets 2 delivered onto the inclined plate 74 roll on this inclined plate 74 and are transferred onto the carry-out conveyor 75, and are carried out by the carry-out conveyor 75 to a predetermined location.

In addition, each fuel pellet 2 is placed on the end face inspection table 3, 72.
While being transferred on the rolling table 61, both end faces are inspected visually or with an optical instrument, and while being transferred on the rolling table 61, its side surfaces are inspected visually or with an optical instrument.

The arrangement of 25 fuel pellets 2 in 5 rows and 5 columns on the end face inspection tables 3 and 72 and the rolling table 61 is because the number of fuel pellets 2 discharged from the grinder is 0.5 seconds/piece. The inspection time for each group in end face and side face inspection is 0.5 x 5 rows x 5 columns = 12.5 seconds>
This is because the practical minimum time of about 10 seconds can be satisfied.

According to this embodiment, the posture of the fuel pellet 2 can be automatically changed between the lying state and the standing state, and the fuel pellet 2 can be automatically rotated in the lying state, so that the inspection operator can inspect the end face. Inspection is extremely easy because all you have to do is look at the inspection tables 3 and 72 and the rolling table 61 and take out the defective products. This eliminates variations in inspection time among inspection workers, significantly shortening inspection time, and significantly reducing the labor of inspection workers. Further, since the fuel pellets 2 are in a lying position when being carried out, the fuel pellets 2 can be easily stored in a tray (not shown). In addition, an inspection worker finds a defective fuel pellet 2 through visual inspection, sends a signal indicating its position to an electric control device by remote control using a switch, etc., and removes the defective fuel pellet 2 by a robot or the like. You can also do that. Furthermore, by using a combination of a television camera device and an image processing device to inspect the end and side surfaces of the fuel pellet 2, the same surface of the same fuel pellet can be inspected twice, and in this case, the minute It is possible to cover defects caused by defects and improve the reliability of inspection, and in this case, even if a failure occurs, it is of course possible to allow the inspection operator to perform an alternative inspection. be.

In addition, in the above embodiment, FIG.
As shown in the inspection order in FIG. 16, the attitude of the fuel pellets 2 conveyed by the carry-in conveyor 1 was changed and both end faces and side surfaces thereof were inspected. However, the present invention is not limited to this; As shown in the figure, the attitude of the fuel pellet 2 may be changed to inspect both end faces and side surfaces.Also, as shown in the third inspection sequence in the figure, the piston rod of the cylinder mechanism (not shown) may be inspected. A push plate (not shown) is attached to the tip of the push plate, and this push plate pushes out the cylindrical body 2 on the carry-in conveyor 1 from one side of the column in a direction perpendicular to the axis of the column body 2. A rolling table 6 provided adjacent to the
The fuel pellet 2 may be transferred onto the rotary table 61 and inspected on the side surface thereof, and then the attitude of the fuel pellet 2 may be changed and both end surfaces thereof may be inspected.

Further, in each of the above embodiments, an example was explained in which the present invention was applied to the visual inspection of fuel pellets 2, but the present invention is not limited to this, and it goes without saying that the present invention can also be applied to the visual inspection of a cylindrical body. It is.

As explained above, according to the present invention, the traveling direction of a plurality of cylinders that are continuously sent in a row on the carry-in conveyor is changed every predetermined number, and those that are upright are placed in that position while lying down. The object is transferred while being rotated, the end face or side surface of the cylindrical body is inspected, and the posture of these cylindrical bodies is changed a predetermined number of times, and each time the posture is changed, a predetermined number of cylindrical bodies are rotated in an upright or lying position. Since the cylindrical body is transported in a predetermined direction and the uninspected end face or side surface of the cylindrical body is inspected, the inspection operator only needs to look at the end face inspection table and rolling table and take out the defective cylindrical body. It is extremely easy to inspect, and it is also possible to inspect three groups of cylindrical bodies at the same time, including two end face inspection tables and a rolling table. This eliminates variations in inspection time among inspection operators, and significantly shortens inspection time. Inspection efficiency can be greatly improved by significantly reducing the labor of inspection workers, and labor savings can be achieved by eliminating wasted labor involved in transporting trays, etc. Furthermore, remote control allows By incorporating an operating electric control device and a weight and dimension measuring mechanism, it is possible to conduct a fully automatic inspection of a cylindrical body.
