Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a method and apparatus for stuffing cotton into rag dolls.

[Conventional technology]

Cotton for rag dolls is generally made by compressing and hardening chemical fiber cotton and selling it as solid cotton in the form of squares weighing about 150 kg. Conventionally, this solid chemical fiber cotton was broken down by hand, made into fine pieces, and then sprayed. This was stuffed into rag dolls using compressed air using a container.

[Problem that the invention seeks to solve]

If you completely unravel the solid chemical fiber by hand, the volume will become thicker.
Rag dolls can be made with a small amount of cotton, although it will be compressed somewhat during stuffing with compressed air. However, the manufactured dolls lose their elasticity and shrink in a short period of time.

[Means for solving problems]

The present invention has been made by focusing on such conventional problems, and after breaking down the solid chemical fiber cotton into fine pieces, it is formed into beads to increase the volume, and even a small amount of cotton can have sufficient elasticity. The object is to solve the above-mentioned problems by stuffing stuffed toy dolls with cotton that is strong and does not shrink easily.

The method according to the present invention breaks down solid chemical fiber cotton into fine pieces,
The deconstructed synthetic cotton is rotated at high speed in a rotating chamber, and the friction between the synthetic cotton fibers caused by the high speed rotation forms it into beads, and the beads of synthetic cotton are stuffed into a stuffed toy doll using compressed air.

The apparatus implementing the method of the present invention has a supply drum rotatably disposed in a supply chamber for synthetic fiber cotton, which is equipped with claws for breaking solid chemical fiber cotton into fine pieces, and a high-speed rotation chamber is connected to the supply chamber. The high speed rotation chamber is rotatably equipped with a high speed rotation drum having claws for forming synthetic cotton into beads, and a discharge chamber having an injector is connected to the discharge port of the high speed rotation chamber.
