Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a fan, and more particularly to a method for manufacturing a fan in which a coated paper laminated on the front and back of a bamboo bone is sandwiched between elastic plates and attached. is there.

[0002]

[Prior Art and its Problems] A plurality of support rods (11) constituting the fan part (20) of the fan are welded or bonded by superposing the covering paper (2) from the front and back and sandwiching them. However, at this time, since the tips of these bones are scattered, they are likely to be damaged during the production process, and it is difficult to make the pitch between the supporting rods constant in the finished state in which the coated paper is stuck on the supporting rods.

Therefore, in the conventional case, in the case of a bone made of synthetic resin, the tips of the bones are connected to each other to keep the distance between the tips of the supporting rods constant (see Japanese Patent Publication No. 58-48164). ) In addition, since the tips of bamboo rods cannot be connected to each other, unlike the ones made of synthetic resin, by attaching thin paper to the rods before the covering paper is attached, it is possible to support them during the production process. In Japanese Patent Application No. 62-81901, a method of protecting the rods and maintaining a constant gap between them is proposed.

In the above method, the problem that the supporting rods are separated from each other has been solved even in the case of a bamboo supporting rod. However, in order to stick thin paper on the supporting rod, one thin paper is manually attached. Glue each one. On the other hand, from thin paper to coated paper (2)
For example, in the welding method, the lower mold and the upper mold that are in a heated state are attached to each other by a predetermined method of the fan part (20) of the fan covered with the covering paper (2) having the welding layer. This is so-called mechanical attachment, in which the area is pressed from the front and back in a pressed state. Further, after cutting the peripheral portion of the coated paper (2) into a predetermined shape, the coated paper (2) is cut.
As shown in FIG. 6, the cover piece (5) is attached from the front and back sides of the fan to cover the both ends of the strip (51) around the periphery of (2). Is hand-painted again.

As described above, in the conventional method of manufacturing this kind of fan, the hand-pasting work cannot be continuously performed, so that the workability in the manufacturing process is poor. In particular, bamboo fan paper is often required to have the above-mentioned cover piece (5) on both ends of the arc-shaped lower edge (21) of the cover paper (2), and even if the work of winding the fan is not performed, the cover piece Only the attachment work must be done by hand.

In this case, since it is only necessary for the covering piece (5) to be present externally, it is necessary to attach the covering piece to the both ends of the lower edge of the covering paper (2) in order to omit the manual attaching work of this covering piece. It is possible to print in advance. However, with this, each time the design of the coated paper (2) is changed, the shape of the coated piece (5) must be printed on both ends of the lower edge and on both sides, which is troublesome and the printing cost is separate. There is a problem that it becomes necessary and the cost increases.

[0007]

[Technical Problem] The present invention is directed to such a fan unit for fan.
The covering paper (2) is coated and adhered to a predetermined area of the supporting rod (11) group constituting the (20), and the covering piece (5) is formed on both sides of the lower end edge (21) of the covering paper (2). ) Is provided, the problem is to improve the workability in the fan manufacturing process and to suppress the production cost.

[0008]

[Technical Means] The technical means of the present invention for solving the above-mentioned problem is to describe a "coated paper (2) corresponding to the application area of the coated piece (5)".
A notch (50) is formed at both ends of the lower end edge (21) of the fan to substantially match the folded shape of the covering piece (5), and the supporting rod (11) group is covered by the fan part (20) of the fan. While sticking the thin paper (3) in the paper welding area, after sticking the thin paper (3), stick the cover pieces (5) folded in two so that both ends of the lower edge are sandwiched from the front and back. , And then cover the coated paper (2) with the fan (2
It was made to cover and adhere to the predetermined area of 0). "

[0009]

The above technical means operates as follows. In the cover paper sticking area of the support rod (11) which constitutes the fan part (20) of the fan,
After attaching the thin paper (3) by hand,
At both ends of the lower edge of (3), cover pieces folded in two
Put (5) by hand so that it is sandwiched from the front and back. This completes the manual pasting work.

Next, the coated paper (2) is attached to a predetermined area of the fan portion (20) by mechanical attachment. The bottom edge of this coated paper (2)
In advance on both ends corresponding to the sticking area of the covering piece (5) of (21),
Since the notch (50) which substantially corresponds to the shape of the covering piece (5) is formed, the covering piece (5) adhered from the notch (50) by the previous manual attaching step is exposed.

[0011]

[Effect] After finishing all the manual pasting work, the coated paper (2)
Since it can be performed after the machine attaching step, the efficiency of the fan manufacturing process is improved and the productivity is improved. Simply make notches (50) at the bottom edges of both sides of the coated paper (2).
Since it is possible to manufacture a round fan in which (5) appears, there is no problem even if the design of the coated paper (2) is changed, and the production cost does not rise.

[0012]

Embodiments of the present invention described above will now be described in detail with reference to the drawings. As shown in FIG. 1, the fan of the embodiment of the present invention is a bamboo handle (13) and a large number of supporting rods (11) continuous with the handle (13).
The fan part of the fan
The so-called laminated paper having a thermoplastic synthetic resin layer (welding layer) on the inner surface is used as the coated paper (2) for covering both sides of the predetermined area of (20). Further, as the thin paper (3), a thin paper or a resin film that is transparent and transparent is used.

In order to manufacture the fan of this embodiment, first, like the conventional one, a large number of supporting rods (11) are formed in the upper area of the bamboo cut into the width of the handle (13). Split, the supporting rod
In the vicinity of the upper end of the handle (13), which is the base end of (11), bamboo sticks are penetrated left and right and curved upward in a substantially U shape to form a substrate (14). Within the substantially U-shaped substrate (14), the supporting rod is provided.
Spread the (11) so that the distance between them is substantially constant, and by the thread (15) connected to both ends of the substrate (14) so that the distance is maintained, the supporting rod ( 11) Connect the predetermined positions of the group in an arc shape. (See FIG. 1) As a result, the supporting rods (11) are temporarily fixed so as to be maintained at a constant interval, and in this state, as shown by the two-dot chain line in FIG. Glue the thin paper (3) from the front side to the upper side of the thread (15) in 11). As shown in the figure, the lower edge (31) of the thin paper (3) is set in an arc shape along the arrangement area of the thread (15), and the other peripheral edge is supported by the supporting rod.
It should be approximately the same as the stretch area of (11).

Then, a substantially semicircular covering piece prepared separately
(5) is folded in half and the bottom edge of the arc (3
Attach it by sandwiching both ends of 1). As a result, as shown in the figure, the substantially triangular covering piece (5) appears on the front and back of the fan. Up to here is the manual pasting work.

Next, the coated paper (2) is welded to the sticking area of the thin paper (3) by mechanical sticking. This coated paper (2) has an arcuate lower end portion (21) which substantially coincides with the lower end edge (31).
Laminate a sheet of laminated paper so that the surface on which the predetermined pattern is printed in the pattern outline (23) is on the outside and the surface on which the thermoplastic resin layer is formed is on the inside, and weld it on both sides. As a whole, it has a flat tubular shape. As shown in FIG. 2, at the lower side of the flat tubular body, at both ends of the lower edge (21) corresponding to the arrangement position of the covering piece (5), The punching is made slightly smaller than the size of the half-folded covering piece (5) to form a substantially triangular notch (50).

The space between the welded portions (22) (22) on both sides of the flat tubular body is made substantially equal to that between both sides of the supporting rod (11) group. From the open top of this coated paper (2),
Insert (13) and set it so that the bottom edge (21) of the coated paper (2) slightly covers the bottom edge (31) of the thin paper (3). At this time, the space between the welded parts (22) (22) is supported.
(11) Since it substantially coincides with that on both sides of the group, it is temporarily fixed in this set state. As a result, the covering piece (5) attached from above the thin paper (3) from the cutout (50) of the covering paper (2).
Is exposed and the thin paper (3) is covered with the coated paper (2).
The thermoplastic synthetic resin layer on the inner surface of the sheet will contact.

Then, the coated paper (2) is placed in a predetermined area of the fan portion (20).
As in the case of the conventional method for welding the coated paper (2), the fan covered with is placed on the lower mold (41) in the heated state as shown in FIG. ), The upper mold (42) facing it is pushed down. Since the cushion materials (40) (40) made of silicone rubber are disposed on the facing surfaces of the lower mold (41) and the upper mold (42), as shown in FIG. 4, the coated paper (2) Presses the thin paper (3) and the supporting rod (11) in a state of being pressed from the front and back.

At this time, as shown in the same figure, by the action of the cushioning materials (40) (40), each coated paper (2) becomes like the cross-sectional shape of the fan portion (20) and the coated paper The thermoplastic synthetic resin layer on the inner surface of (2) is welded by the cushion material (40) (40) having the transfer heat from the lower mold (41) and the upper mold (42),
The coated paper (2) will be welded to a predetermined area of the fan part (20) of the fan.

After that, as shown by the chain double-dashed line in FIG. 5, the peripheral edge portion of the coated paper (2) excluding the lower end edge (21) is extended from the front end portion of the substrate (14) to obtain a punching line (C). ), The paper fan (2) has a cutout (50) at the lower end on both sides to complete the fan, which reveals the cover piece (5) in appearance. At this time, depending on the degree of sticking of the covering piece, the edge portion of the covering piece (5) may also be cut at the same time.To avoid this, fold the covering piece (5) in the two-fold state. Part of the substrate (14)
It suffices to sandwich the covering piece (5) so deep that it reaches the tip of the.

In this embodiment, the cotton bones are made of bamboo, but it goes without saying that those made of synthetic resin can be similarly produced. In addition, the coated paper (2) is provided with an adhesive layer on the back surface, and the coated paper (2) is formed by pressure-bonding machine attachment.
(2) may be attached to the front and back of the bone.
