Description

  The present invention relates to a pelletized dry ice filling device capable of filling a pellet or the like that is filled with pelletized dry ice by a co-op or the like and filled with the optimum pelletized dry ice.

  Conventionally, as a method of filling pellet-shaped dry ice in a delivery container, manual charging by a hand scoop or a method of transferring the pellet-shaped dry ice into the container by using a conveyor or the like is used.

However, the volumetric type such as manual feeding and conveyor has a drawback that it is difficult to supply the filling amount accurately and continuously at a high speed.
Also, when throwing into a container transported by a conveyor, the container is stopped by a stopper, and the machine is automatically started and stopped frequently, increasing the load on the machine and causing failure. There is a disadvantage that work time is lost due to frequent automatic start / stop.
