To provide a device for accumulating products such as machined components discharged continuously from an automatic machine such as an automatic lathe without scratching or striking them, and accumulating and collecting products, while washing off unnecessary oil or chips deposited on the products essentially for the next step.

Products 8a machined by an automatic machine and discharged continuously therefrom are received by a shooter 1, guided to the rotation center of a tray 2 rotating on a turntable, and discharged to the outside of the shooter from a shooter tip part 1a respectively in the outer peripheral direction, to thereby prevent collision with a product 8b to be discharged next time. The products can be washed simultaneously by supplying washing liquid in the tray 2 and a bucket 3 of a product accumulation tank.
