Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for manufacturing hair color, and more specifically, a main body made of a rod-shaped member having shape retention and plastic deformability is heated with a cold perm liquid. with or without
After wrapping hair around this main body, the rod-shaped member was plastically deformed with fingers, the hair was kept wrapped, and after a sufficient period of time, the plastic deformation was returned to its original state with fingers. The present invention also relates to a method and apparatus for producing a type of hair color in which curling of hair can be achieved by removing the hair from a rod-like member.

[Conventional technology]

As this type of hair color, for example,
The one disclosed in Japanese Patent No. 25503 is known. As shown in Fig. 1, this hair curler is made by inserting a wire 1 covered with a sheath 2 into the central hollow part of a rod-shaped foamed polyethylene 3 with a circular cross section. It is manufactured by fitting the end cap 4.

[Problem that the invention seeks to solve]

In such a conventional example, in addition to the wire and foamed polyethylene covering layer, which are the members that perform the functions required as a hair curler, a sheath and an end cap are required, so there are many parts. There was a problem in that the manufacturing cost was high. Therefore, the present invention has developed a manufacturing method that can quickly manufacture a hair curler with sufficient safety during use at low cost using only the minimum number of components necessary to perform the necessary functions as a hair curler. The aim is to provide equipment.

[Summary of means for solving the problems] In the present invention, the functions necessary for this type of hair curler are achieved by a shape-retaining plastic member and a flexible coating layer covering it. Focusing on this, the following points were the basic design philosophy for manufacturing: 1.) Creating an arch curler from only a shape-retaining plastic deformable member and a flexible coating layer; ii) A shape-retaining material. Each end of the plastically deformable member should be completely covered with a flexible covering layer so as not to damage the scalp during use; Even when used, it should not protrude to the outside, and even if it should protrude, it should not damage the scalp, etc.: iv) A flexible coating with a structure that prevents both from slipping when hair is wrapped around the hair color. To be applied to a layer.

In order to achieve these basic design conditions, the present invention has developed a method and an apparatus for carrying out the method as outlined below.

First, as a shape-retaining and plastically deformable member, for example, copper wire is used. After cutting the copper wire to an appropriate length, the copper wire is deformed into a ring-like or hook-like shape with both ends parallel to each other. , prepare a large number of these in advance.

On the other hand, a long strip of foamed synthetic resin with a rectangular cross section, for example foamed polyethylene, is prepared, and the copper wire coated with neorene adhesive, for example, is glued onto this long foamed synthetic resin at regular intervals. be done. Next, a foamed synthetic resin of the same size is bonded by heat fusion to the side of the foamed synthetic resin to which the copper wires have been bonded at regular intervals. In this way, a long piece of foamed synthetic resin with built-in copper wires at regular intervals has a nearly square cross section.
Next, by continuously cutting off the even corners of this long object diagonally, a long object with a hexagonal cross section is obtained. A hair curler is manufactured by cutting the hair at intervals.

〔Example〕

Next, each process of the present invention and the apparatus used therein will be explained based on examples.

1) Preparation of materials As shown in Fig. 3, a copper wire 5 of a certain length with a ring-shaped part or hook-shaped part 6 formed on the same plane at both ends, and a length of foamed synthetic resin with a rectangular cross section. A large number of items will be prepared.

it) Adhesion of copper wire to a long piece of foamed synthetic resin In order to attach the above copper wire to a foamed synthetic resin with a rectangular cross section, it is necessary to first apply adhesive to the copper wire, and the copper wire must be Since the adhesive must be applied horizontally and correctly to the center of the foamed synthetic resin, the following equipment is used. ff14
5 and 6, support stands 8 are fixed to the upper surface of the flat plate 7 at appropriate intervals so that their upper surfaces are parallel to each other. Supports 9 and 10111 are respectively fixed to the upper part of the support base 8 in a direction orthogonal to the longitudinal direction of the flat plate 7, while a pair of side plates 12.
13 are fixed respectively.

The upper part of the support 8.9.10 has a tip 15 provided with a substantially V-shaped cut part 14 with an open top, as shown in FIG. When placed on the V-shaped cut portion 14 of the body, the copper wire is maintained horizontally and is held so as not to shift laterally. The outer two supports 8.10 of the three supports 8.9.10 have a spacing between their outer sides that is approximately equal to the spacing between the necks of the ring-like or hook-like parts 6 of the copper wire. as a result of which longitudinal movement of the copper wire is also prevented when it is placed on these supports. Although the intermediate support 10 is not essential, it is advantageous to have one or five or more intermediate supports 10 to prevent misalignment. The support band is placed so that when the copper wire is actually placed on the support, the copper wire rotates and the ring-shaped part or hook-shaped part of the copper wire does not rotate and become vertical. A horizontal plate 16 or horizontal line is provided on which a ring-shaped or hook-shaped part of the copper wire is horizontally placed.

Several pairs of such supports and horizontal surfaces are prepared in the longitudinal direction on the support frame, and the figure shows an example in which two pairs are prepared.

After each copper wire 5 is placed on such a support, an adhesive coating device as shown in FIG. 7 is used to apply adhesive to the upper surface of the copper wire 5. This uses a plunger to intermittently feed the connecting agent from the adhesive reservoir to the tip of the nozzle 20 through an adjustable throttle.
Since the brush 21 is provided around the tip of the nozzle 20, the brush 21 will be wetted with the adhesive. This adhesive-wetted brush 21 is then lowered by a cylinder 23 and, after contacting the copper wire 5, is moved longitudinally by a cylinder 22 to apply the adhesive onto the copper wire 5.

In order to ensure complete application, the brush 21 should be allowed to stroke the copper wire 5 on the return trip as well. After the coating operation is completed, the brush 21 is pulled upward by the cylinder 23. In actual work, in order to perform this application work efficiently, multiple rows of the flat plate 7 on which the copper wires 5 are placed are treated as one work unit, and an application brush 21 connected to the adhesive supply plunger is used.
is a number corresponding to the number of multiple rows of this support frame, or in some cases an integral multiple thereof depending on the number of copper wires placed in each row, at intervals, for example, on a slider that can be moved up and down and left and right. It is efficient to prepare adhesive application brush assemblies and process a large number of them at the same time.

In this case, the flat plate 7 has multiple rows as shown in FIG.
They are arranged in the form of an endless strip and moved endlessly using a suitable drive device. For example, the endless strip is stopped by a microswitch every time a plurality of rows are moved, and the endless strip is processed by an adhesive application brush assembly. In this case, the adhesive application brush assembly is simply pressed against the copper wire during operation, and the adhesive is applied to the copper wire by moving the support frame in the longitudinal direction. It may also be configured such that it is applied.

The flat plate 7 on which the copper wire coated with adhesive is placed is then dried to remove the solvent in a drying device 24. After this, the support frame advances to the next working area, where the foamed synthetic resin with a rectangular cross section is
The side plates 12 and 13 on the support base 8 are used as lateral position regulating gauges and are inserted by a roller device, thereby completing the adhesion between the copper wire and the foamed synthetic resin having a rectangular cross section. It is pulled out from between the side plates 12 and 13. In this bonding operation, the elongated member of the foamed synthetic resin may be supported upward, for example, and the two members may be bonded together by pressing against a support frame on which the copper wire coated with adhesive is placed.

i) Lamination process A long piece of foamed synthetic resin with copper wire bonded to it at regular intervals is guided into the inside of the laminator by a guide roll of the laminator. On the other hand, from the other roller of the laminator, a long piece of foamed synthetic resin to which the copper wire is not bonded is guided into the inside of the laminator, and the opposing surfaces of the two are heated, for example, by hot air means, and then brought into contact with each other. A large number of rollers apply pressure to the foamed synthetic resin until it cools down and becomes one body.

iv) Shaping process In this way, copper wires are built in at regular intervals, but externally the cross section doubles as a result of heat fusion.
A long piece of synthetic resin foam with a square cross section is guided to a first cutter 30 as shown in FIG. The cutter 32 sequentially cuts off the upper right corner.

In this way, the long piece of foamed synthetic resin whose upper side has a trapezoidal cross section is subjected to the same process on the lower side using a second cutter machine, resulting in a final hexagonal cross section. 11. The second cutter may have the same structure as the first cutter, and may process the foamed synthetic resin whose upper side has a trapezoidal cross section by inverting it. The long piece of foamed synthetic resin shaped into a hexagonal cross section in this way is cut at regular intervals in the length direction at a position where the end of the copper wire is not exposed, resulting in the final product. A hair curler as shown in is obtained.

Note that the above examples relate to methods and devices for manufacturing hair curlers with specific shapes and structures, but some or all of these manufacturing methods and devices can be applied to other hair curlers with similar shapes and structures. It can be used for manufacturing things. For example, ノ＼
It can be used for the production of household goods, cushioning materials, fillers, toys, etc., and in such cases, whether ring-shaped parts or hook-shaped parts are not formed at both ends of the shape-retaining plastically deformable member. Alternatively, the ends can be folded back or crushed flat before use.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to obtain a hair curler in which a shape-retaining plastic deformable member provided with ring-shaped parts or hook-shaped parts at both ends is firmly embedded in a foamed synthetic resin. , it is advantageous in terms of manufacturing costs as it requires fewer parts compared to conventional products, and the appearance is completely covered with foamed synthetic resin, so even when this hair curler is soaked in cold perm solution, it can be easily removed from the gaps. There is no waste caused by excess liquid dripping. In addition, the ring-shaped parts or hook-shaped parts arranged at both ends of the shape-retaining plastic deformable member, which is the core material, increase the stability of placement on the support frame during the bonding process during manufacturing. It significantly improves the adhesion between the copper wire and the foamed synthetic resin, and even if the foamed synthetic resin inner lining breaks during use due to rough handling,
It is very advantageous because it does not damage the scalp etc. due to its structure.
