It is arranged on the row of the product tray 7 with a space portion without the pellets 8 that has been removed and removed. In the fuel manufacturing facility, the number of the grooves 7a for accommodating the pellets 8 provided in all the product dishes 7 and the length of the grooves 7a are made the same, and the quantity of the pellets 8 accommodated is made constant. It is considered that it is desirable for operation to count the number of pellets 8 to be handled by counting. However, in the conventional apparatus, the pellets 8 determined to be defective in the inspection stage and removed from the inspection table 1 are not refilled in the row, so that even if the number of the product trays 7 is counted, There is a problem that it is not possible to grasp the number of pellets. For this purpose, each groove 7a of the product dish 7
It is necessary to provide a device that counts the number of pellets 8 contained in each row for each row, or a special device for replenishing the pellets 8 that have been removed. Inevitably, there are problems in terms of equipment arrangement such as becoming expensive and economical problems.

容易となる。It should be noted that even during the operation of accommodating six pellets 8 in the above-mentioned product dish 7, the inspection table 1 holds the pellets 8.
Are performed in the same cycle, and are sequentially sent to the temporary placement position of the collection table 11. However, during the six cycles in which six pieces are moved to the temporary storage position, the collection table 11
Since the three rows of pellets 8 at the upper standby position can be processed in three cycles of operation, the operation is not congested. Therefore, the relationship between the number of the grooves 1a of the inspection table 1 and the number of the pellets 8 temporarily placed on the collection table 11 is set so as not to cause congestion as described above. At this time, the predetermined number of the pellets 8 temporarily placed on the collection table 11 is as follows:
If the number is set to be a divisor of the number accommodated in one groove 7a of the product tray 7, the operation control of the device for collecting the pellets 8 becomes easy.

に行うことができる。As described above, the present invention provides an inspection table on which a plurality of pellets are placed for inspecting the plurality of pellets,
Arrange a collection stand to temporarily place the pellets after inspection between the product tray on the tray receiving table that contains the pellets after inspection,
The pellets sent to the temporary placement position on the collection table by the inspection pusher are moved by the collection pusher to the product tray by the number of rows that have reached the predetermined number, and then sent to the product tray by the alignment pusher one row at a time. A predetermined number of pellets are sequentially and regularly fed into a row of product dishes. Therefore, the number of pellets stored in the product dish is always constant, and the number of pellets can be grasped by counting the number of product dishes. It is possible to easily control the number of pellets without preparing a special device for performing the operation.
