A valley that stops the cylinder is formed in the middle of the side slope,
Moreover, when the number of feed rollers is n, the rolling distance of the cylindrical body from the valley to the valley of two adjacent feed rollers is set to (n-1) / n times the circumference of the cylindrical body. Each feed roller rolls over the notch feed part from the valley part of the feed roller to a steady position where the fed cylinder is stopped at the valley part, and the notch feed part and the column body transfer direction. An intermittent reciprocating rotation mechanism that swings in the same direction so as to take a tilted position that locks the cylindrical body with the outer peripheral surface of the adjacent feed roller is provided, and each feed roller moves from the tilted position to the steady position. The columnar body locked at the inclined position is moved to the trough of the adjacent feed roller when returning to.

The side part facing toward shifts by 1/4 of the circumference. Then, all the side surfaces of the pellets 17 that have entered the valleys 16 of the fourth row feed rollers are inspected here. Finally, as shown in Fig. 5 (h), a pellet 17 with the entire circumference being inspected
Are sent from the fourth row feed roller 2 onto the discharge plate 12 and hit the stop plate 12a to stand still. The pellets 17 on the discharge plate 12 are detected by the photodetector 13, and the adsorption device 19 descends according to the detection signal, adsorbs the pellets 17 ... . The adsorber 19 discharges the pellets immediately after the pellets 17 are transferred to the next process.
12 Return to the top and wait for the next pellet delivery.

Rolls to the adjacent feed roller 2 from valley 16 to valley 16
Since it rotates 3/4 turn and remains stationary, the side surfaces facing upward in the valleys 16 of the pellets 17 deviate by 1/4 of the circumference, and all the side surfaces are inspected by the feed roller 2 in the fourth row. Will be. Further, since the side face portion adjacent to the side face portion of the pellet 17 which faces upward in a certain feed roller 2 always faces upward in the next feed roller 2, these side face portions are substantially partially overlapped and the appearance Eliminate oversight in inspection. Further, since the pellets 17 remain stationary in each valley 16 of the feed roller 2 for a certain period of time, the visual inspection can be reliably performed and the fatigue of the inspector's eyes can be greatly reduced. Also, the pellet 17
The loading and unloading of… can be done automatically and continuously by the adsorbers 18 and 19, and the pellets 17… can be sent automatically, so the inspection can be done in a flowable manner, and the inspection time can be shortened and the inspection can be shortened. Standardization of work and labor saving can be achieved.

利点もある。EFFECTS OF THE INVENTION The cylindrical rotary feed device of the present invention includes:
A mountain shape whose central portion projects in the radial direction to form the top,
A notched feed portion is formed for rolling the cylindrical body, and a valley portion for stopping the cylindrical body is formed in the middle of the slope from the top of the notched feed portion on the side opposite to the cylindrical body transfer direction, and the number of feed rollers is n. Then, the rolling distance of the cylinder from the valley to the valley of two adjacent feed rollers is (n)
-1) / n times, and each feed roller rolls over the notch feed part from the valley position of the feed roller and the steady position where the transported columnar body is stopped at the valley part. An intermittent reciprocating rotation mechanism is provided that swings in the same direction so as to obtain an inclined position for locking the cylinder between the notch feed portion and the outer peripheral surface of the feed roller adjacent in the cylinder transfer direction, When each feed roller returns from the tilted position to the steady position, the columnar body locked at the tilted position moves to the valley of the adjacent feed roller. Therefore, each feed roller has an intermittent reciprocating rotation mechanism. By rotating in one direction by means of a roller, the cylindrical body placed in the valley of one feed roller is rolled and stopped at the outer peripheral surface of the next feed roller, and then the intermittent reciprocating rotation mechanism described above. Rotate each feed roller in the opposite direction by By moving one feed roller to the valley of the next feed roller, the cylinder can be inspected with the notched feed portion of the feed roller stationary, and therefore the visual inspection from above can be performed reliably and completely. It can be done over the peripheral surface, and the fatigue of the inspector's eyes can be greatly reduced. In addition, the cylinder can be moved (rolled) smoothly, impacts etc. are not applied to the cylinder, and dust adhering to the cylinder etc. Since it can be easily dropped from between the feed rollers and removed, and the cylindrical body can be automatically transferred, standardization of inspection work and labor saving can be achieved. Moreover, the change of the observation area due to the intermittent transfer of the cylindrical body is controlled by the intermittent reciprocating rotation mechanism (driving means).
Since it can be carried out by using only n feeding rollers, there is also an advantage that the configuration is relatively simple and the cost is low.

A plurality of feed rollers for rotatively moving a columnar body are arranged in parallel so as to be rotatable at equal intervals, and a plurality of columnar bodies having substantially the same diameter are rotatably moved on the feed roller. In the cylindrical body rotary feed device configured to perform an appearance inspection of each columnar body, each of the feed rollers has a mountain-shaped notched feed portion in which a central portion thereof protrudes in a radial direction to form a top. Is formed, and a valley portion for stopping the columnar body is formed in the middle of the slope on the side opposite to the columnar body transfer direction from the top of the notch feed section, and when the number of feed rollers is n, adjacent two
The rolling distance of the cylinder from the valley to the valley of the book feed roller is set to (n-1) / n times the circumferential length of the cylinder, and the feed roller moves the cylinder to be transferred. The cylindrical body is engaged between the steady position where it is stopped in the valley portion and the notch feeding portion by rolling over the notch feeding portion from the valley portion of the feeding roller and the outer peripheral surface of the feeding roller adjacent to the columnar body transport direction. There is an intermittent reciprocating rotation mechanism that swings in the same direction so that the inclined position to stop and the inclined position can be taken, and when each feed roller returns from the inclined position to the steady position, the columnar body locked to the inclined position is adjacent. The cylindrical rotary feed device is characterized in that the feed roller is moved to the valley portion of the feed roller.
