Description

[0001]
[Industrial application fields]
The present invention relates to a method for manufacturing a school bag, a student bag, and other appropriate bags with a cover.
[0002]
[Prior art]
Conventionally, a cover-equipped scissors first cuts the material that composes the scissors body so that it is separated separately according to the shape of each constituent part such as the housing part, the back part, the cover part, etc. It was manufactured by sewing and joining together many separated materials.
[0003]
However, in such a manufacturing method, there are many processes that require complicated manual work for cutting and sewing. In particular, there were many places where the materials were connected to the opening where the objects were taken in and out, and it took time to form them. Therefore, it is difficult to save labor and mechanization, and the cost is high.
[0004]
Further, the overlaid ridge manufactured by this conventional manufacturing method is made of a large amount of material and has many sewn portions, so it is heavy and has low strength. In particular, since the cover portion is frequently bent or pulled during opening and closing, the sewn portion between the back portion and the cover portion is easily damaged, and often cannot be used for a long period of time.
[0005]
[Problems to be solved by the invention]
Therefore, the present invention has few processes that require complicated manual work, and particularly requires less labor to form the opening portion, is easy to save labor and mechanization, is low in cost, and lightweight. Thus, it is an object of the present invention to provide a method for manufacturing a covered rivet that is excellent in strength and can manufacture a covered fold that can withstand long-term use.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the present invention takes the following technical means.
[0007]
In the manufacturing method of the cover-equipped bag according to the present invention, one flat material constituting the bag storage portion, the back portion, and the cover portion is recessed so as to form a storage space by embossing, and further recessed. The outer end of the housing portion is cut in accordance with the opening shape of the bag, and the boundary between the housing portion and the back portion, and the back portion and the covering portion is bent and formed.
[0008]
While cutting the outer end of a storage part according to the opening shape of a collar, you may cut the outer periphery of a raw material into a required shape.
[0009]
Moreover, you may attach an accessory suitably to the raw material of the cut state.
[0010]
[Action]
As a result of employing the above-described means, the present invention has the following effects.
[0011]
In the method for manufacturing the overlaid scissors according to the present invention, each component of the scissors main body is continuously formed on a single material by embossing, so that there are fewer portions that need to be cut or sewn. In particular, the opening shape can be easily formed by cutting the opening portion.
[0012]
【Example】
The configuration of the present invention will be described below with reference to the drawings showing the embodiments.
[0013]
In the manufacturing method of the cover-equipped bag according to the present invention, one flat material constituting the bag storage portion, the back portion, and the cover portion is recessed so as to form a storage space by embossing, and further recessed. The outer end of the housing portion is cut in accordance with the opening shape of the bag, and the boundary between the housing portion and the back portion, and the back portion and the covering portion is bent and formed.
[0014]
What was shown in FIG. 1 is the raw material 1 used for the manufacturing method of the overlaid bag of this invention. This material 1 has a flat rectangular plate shape, and at least a portion that can be recessed by a stamping process, which will be described later, uses a relatively hard vinyl chloride or urethane material in order to maintain the shape. desirable. It should be noted that a hard material and a soft material may be superposed so that at least one side of the ridge is softened.
[0015]
First, the material 1 is depressed by embossing so that an accommodation space is formed in the finished bag in the embossing step. In the embossing process of this embodiment, since the bag to be manufactured is a school bag, as shown in FIG. 2, the accommodating portion 2, the back portion 3, the covering portion 4, and the opening / closing portion 5 along the longitudinal direction of the material 1. The folding part 6 is formed at each component part of the cocoon body and the boundary between the component parts.
[0016]
Each component part of the bag main body can be continuously formed on one material 1 in this way, so that labor saving and mechanization are easy, and the material 1 has a portion that is wasted except for the outer peripheral portion. The material 1 can be used effectively.
[0017]
Next, the material 1 that has undergone the embossing process is cut along the dotted line shown in FIG. 2 in the next cutting process. FIG. 3 is a view showing the cut portion, and the outer end 7 of the recessed portion 2 of the material 1 is cut so as to correspond to the completed opening shape of the bag, and the opening portion 8 is formed in the storage portion 2. It is formed.
[0018]
In this cutting process, since it is not necessary to separate each component part of the bag main body separately, the number of cutting parts is small, and only the outer peripheral part of the material 1 may be cut. Labor saving and mechanization are easy because it is only necessary to cut straight lines except for the end 7. Moreover, the wasteful amount of waste material 1 that cannot be used and the amount of waste generated are extremely small, and the removal work is easy.
[0019]
Further, the material 1 that has undergone the cutting process is bent at the folding portion 6 to be formed into the basic shape of the heel body in the next bending process. Then, by sewing the necessary portion of the material 1 having the basic shape, the heel as shown in FIG. 4 is completed. In this embodiment, the periphery of each component is sewed so that the periphery of each component is folded inward and the periphery of the housing 2 and the back 3 is sewn.
[0020]
In this embodiment, appropriate accessories such as the back strap 9, the storage portion 10, the cushion material 11, and the opening / closing latch 12 are attached to the cut material 1 before proceeding to the bending process. Since the cut material 1 is not yet completely three-dimensional, it is easier to attach the accessory than the material 1 after it is made into a three-dimensional basic shape by a bending process, and its mechanization is also Easy.
[0021]
As described above, in the method for manufacturing a cover-attached bag according to the present invention, since there are very few parts that need to be cut or sewn, there are not many complicated manual processes, and labor saving and mechanization are easy. In particular, it is only necessary to sew the peripheral edge portions on both sides of the accommodating portion 2 and the back portion 3 with respect to the opening portion 8, and it does not require much labor.
[0022]
Further, the overlaid ridge manufactured by the manufacturing method of the present invention is formed by bending a single material 1 in which each component is continuously formed, and the material 1 of each component is Since there are few overlapping parts and parts to be sewn, the amount of the material 1 used can be reduced, the weight can be reduced, and the strength is excellent.
[0023]
In addition to the above-described school bag, the method for manufacturing a bag with a cover according to the present invention can manufacture a student bag and other appropriate bags with a cover.
[0024]
【The invention's effect】
The manufacturing method of the overlaid scissors according to the present invention has the above-described configuration, and each constituent part of the scissors main body is continuously formed on one material by embossing, and cutting or sewing is performed. Since the number of necessary parts is small, there are few processes that require complicated manual work, and it is easy to save labor and mechanization, especially at low cost because it does not take time to form openings. In addition, it is possible to produce a covered ridge that is lightweight, excellent in strength, and can withstand long-term use.
