である。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a skeleton for a round fan, and more particularly to a method for producing a skeleton in a fan in which a large number of radially extending branch bones are coated with coated paper.

るようになった。2. Description of the Related Art Fans are seasonal commodities, and therefore, they must be mass-produced at certain times. Therefore,
Traditionally, there has been a call for streamlining production. Therefore, recently, as disclosed in Japanese Patent Publication No. 58-20605, a method has been adopted in which a coated paper is attached to a synthetic resin bone by heat welding.

うちわが完成する。In this method, the coated paper to be attached to the clavicle group of bones is a so-called laminated paper, and the synthetic resin layers on the back surface of the coated paper are heated in a state of being opposed to each other through the clavicle group.・ Wear under pressure. As a result, the synthetic resin layers of the front and back cover papers located between the clavicle groups are melt-bonded to each other, and the cover papers are attached to the front and back surfaces of the clavicle group. Trimming this coated paper sticking part to a predetermined shape and finishing processing such as curling,
The fan is completed.

にも他のごみとの特性の相違から問題がある。According to this fan manufacturing method, the work of sticking the coated paper is greatly improved as compared with the pasting method of pasting glue manually. On the other hand, the round fan produced in large quantities as described above is often used as it is and then discarded as it is. In fact, many of them can withstand practical use. However, the round fan produced by the above method has the entire bone made of a thermoplastic synthetic resin such as polypropylene, and the synthetic resin layer formed on the back surface of the coated paper is the same. There is also a possibility of being. Also, when treated as garbage, there is a problem due to the difference in characteristics from other garbage.

湯流れが悪いからである。Therefore, in order to solve such inconvenience, it is considered to use a biodegradable polymer as a constituent material of a bone body having a large number of branch bones. For example, it is a biodegradable polymer mainly composed of starch obtained from corn or potato. However, when the conventional bone body is injection-molded with the biodegradable polymer as it is, the time required to form the bone body is significantly increased,
As a result, the productivity of the fan is reduced. This is because the flow of molten metal during injection molding of the biodegradable polymer is worse than that of conventional thermoplastic synthetic resins.

(13) A method for manufacturing a skeleton for a fan in which groups are radially extended ”
In the above, it is an object to make it possible to shorten the time required for molding the bone body of a fan made of a biodegradable polymer.

(11) is extended and is integrally connected by a connecting piece (14) at the tip of these branch bones (13) and (13) groups, the cross section of each branch bone from the tip to the frame (1
1) The flat shape of each branch bone (13) is set to be relatively large while gradually flattening and widening from the joint with the joint, and this bone body is manufactured by injection molding with a biodegradable polymer. I did that. ”

素材の流動性が促進されたものとなっている。The above technical means operates as follows. At the time of injection molding of the bone body, the material is injected into the molding space in the mold from the part corresponding to the handle (2) or the handle mounting part in the molding die, and further, this handle (2) or the handle mounting part. Part to frame (1
1) → Flows to the branch bone (13) or the connecting piece (14). By the way, the ribs (13) (1) where the flow of the molten material is most remarkable during molding
In group 3), each carcass (13) is set larger than the carcass (13) of a normal skeleton, and the carcass (13) gradually becomes flat and wide from the distal end to the proximal end. Therefore, the fluidity of the material in this part is promoted.

Even when the bone body is injection-molded, the molding time does not become long. Also, each branch bone (13) is generally larger than the branch bone (13) of a normal skeleton, but since the cross section is configured to be flat and wide, when a coated paper is attached to form a fan, At the time of use, the degree of flexure of this branch bone (13) is also sufficient.

Since the bone body can be molded by the biodegradable polymer, the bone body is biodegraded when it is discarded in an unusable state. Therefore, it is possible to eliminate the inconvenience of being left in the natural world as artificially generated waste. That is,
It becomes recyclable.

In addition, productivity is improved. When the coated paper is attached and used as a fan, the degree of flexure of the branch bones (13) is sufficient, so that the fan action of the coated paper attachment area in use is sufficient and the usability is good.
