A holding piece 5b for holding the chopsticks P when stopped at the uppermost end of the inclined conveyor is provided, and a scraping and holding member 5 is provided.

Reference numeral 6 denotes a feed shooter provided on the exit side of the inclined conveyor 3 for transferring chopsticks P of rod-shaped articles dropped from the inclined conveyor 3 to a single item receiving portion 8 of a rotary single item feeding device 7.

The chopsticks P received by the single item receiving portion 8 are dropped onto the opening / closing hopper 10 through the second auxiliary shooter 9 as the rotary single item feeding device 7 rotates. Open and close hopper 1
The opening and closing of 0 is controlled in an interlocking or intermittent manner with a supplied device, for example, an automatic packaging device for bento.

Note that S4 is a sensor for detecting whether chopsticks P are present on the discharge side of the inclined conveyor 3, and the detection of this sensor S4 allows the inclined conveyor 3 to advance and the feeding of the inclined conveyor 3. Even if the rod-shaped article P is not transferred to all the crosspieces, it can be filled. Further, S5 is a sensor for detecting whether or not there are chopsticks in the single item receiving portion 8, and when there is no chopstick P in the single item receiving portion 8, the highest chopstick P of the inclined conveyor 3 is sent out and filled.

With the above construction, when the worker puts the rod-shaped articles, that is, the chopsticks P, into the hopper 1 and activates them, the hopper 11 is turned over and the inclined conveyor 3 via the auxiliary shooter 2. When chopsticks P are supplied to the auxiliary shooter 2 and an appropriate amount is supplied onto the auxiliary shooter 2, the sensor S1 detects and returns to the original position.

Then, the chopsticks P supplied onto the inclined conveyor via the auxiliary shooter 2 are picked up by the feed bar 4 and conveyed toward the discharge side, and when the chopsticks P are superposed and conveyed, It is scraped off by the scraping piece 5a.

Then, the chopsticks P discharged from the inclined conveyor 3 fall on the feed shooter 6 and the rotary single-piece feeding device 7

Will be ejected and will fall. However, in that case, only one of the two chopsticks P dropped to the feed shooter 6 is fed by the rotary single-piece feeding device 7, but the other one falls from the feed shooter 6.

When the sensor S5 detects that the chopstick P is in the single item receiving portion 8, the rotary single item feeding device 7 rotates 1/4, and stops when the chopstick P is not in the single item receiving portion 8, while detecting the other. The inclined conveyor 3 is driven in synchronization with the signal to feed the chopsticks P and drop them on the shooter 6.

Therefore, according to the present invention, the chopsticks can be automatically sent out one by one and can be accurately supplied to the subsequent device. Conventionally, the chopsticks, which were previously supplied by the operator to the automatic packaging device, are chopsticks. The supply work will be much easier. Furthermore, since the hopper 1 is detachable in the apparatus of the embodiment, when changing the chopsticks in different packaging bags or changing the supply of chopsticks to a fork or spoon, replace the hopper with another fork or spoon. By doing so, it is possible to respond immediately.
