It is.

[Conventional technology]

Since disposable chopsticks are consumed in large quantities, it is desirable to mass produce them and provide them at low prices.

At present, there are bag-making machines that continuously manufacture paper bags 1, but there are two mechanical chopsticks inside this paper bag 1.
Since there is no chopstick bag filling machine that fills chopsticks one by one, the current situation is that a worker (inside job) fills each chopstick bag one by one into the paper bag 1, so there is a limit to mass production. The current situation is that disposable chopsticks are provided at such a high cost.

For this reason, one side of the opening of the paper bag is cut off diagonally to make it easier to stuff chopsticks into the bag.

The present invention solves this problem, and can simultaneously manufacture paper bags and automatically stuff disposable chopsticks into the paper bags.This invention has excellent workability and allows mass production of bag-packed chopsticks. However, it is a technical problem to provide an automatic chopstick bagging device in a disposable chopstick bag making machine that can be provided at low cost.
