Description

Manufacturing method of bamboo tatami

The invention relates to a method for manufacturing tatami, in particular to a method for manufacturing bamboo tatami.

"Stacked seats" are commonly known as "tatami". The tatami is mainly composed of stacked beds, stacked tables, bottom cloth materials, cloth edges and other parts. Traditionally, the manufacturing process of the stacked bed is mainly to purify, steam, fume, heat and dry the superior coconut bristle, wheat straw or straw, and then press it into the main shape with machinery and equipment, and now the stacked bed will also use EVA rubber foam material To manufacture. The stacked table is mostly woven from rush grass, or it can be made of bamboo. As for the cloth edge, it can be covered with the selected cloth surface and sewn.

However, when the material of the laminated surface is bamboo, the laminated bed (for example, made of EVA rubber foam material) is a flexible material, and the bamboo is a hard material. Therefore, when sewing the fabric, the bamboo It will easily break due to lack of support, and may even cause needle breakage. Therefore, it is necessary to seek a solution.

Therefore, the object of the present invention is to provide a method for manufacturing bamboo tatami.

Therefore, the manufacturing method of the bamboo tatami of the present invention includes the following steps: (a) providing a bamboo tatami body, a sewing machine including a needle that can move up and down, an edge band, and an edge device, wherein the The bamboo tatami body includes a bottom fabric, a stack of beds, and a bamboo sheet stacking table stacked from bottom to top; (b) The bamboo tatami body is turned over so that the bottom fabric becomes the uppermost layer, and the bamboo The sheet stacking table becomes the lowermost layer; and (c) The edge banding device is used to wrap the edge banding on one side of the bamboo tatami body to be sewn, and the side to be sewn is sewn by the sewing machine, During the downward movement of the sewing machine, the stitching belt, the bottom fabric, the stacked bed, the bamboo sheet stacking surface, and the wrapping belt are sequentially penetrated.

The effect of the present invention is that because the manufacturing method of the bamboo tatami of the present invention includes the step (b) of turning the bamboo tatami body upside down first, the cloth edge is sewn under the condition that the bottom fabric material is on and the bamboo sheet stacking surface is down. Therefore, there will be no problem that the bamboo sheet is easily broken due to lack of supporting force, and there will be no problem of broken needles.

1 to 3, an embodiment of the manufacturing method of the bamboo tatami of the present invention includes the following steps. First, as shown in step 61, a bamboo tatami body 10, a sewing machine 2, an edge band 3, an edge unit 4, and a carrying platform 5 are provided.

As shown in FIG. 2, in this embodiment, the bamboo tatami body 10 includes a bottom cloth 101 stacked from bottom to top, a stack of beds 102, and a bamboo stack table 103, wherein the stack of beds 102 The material may be, for example, ethylene/vinyl acetate copolymer (EVA) rubber foam material, but the invention is not limited thereto.

As shown in FIG. 3, in this embodiment, the sewing machine 2 includes a needle 21 for sewing the hemming tape 3 on the bamboo tatami body 10 and movable up and down, and a needle thread coil wound with a needle thread 22. A bobbin case, a bobbin coil placed in the bobbin case and wound with a bobbin thread, a motor, and a pressing plate 23 for pressing the bamboo tatami body 10, wherein, as shown in FIG. 3 due to the drawing angle, Therefore, the bobbin case, the lower coil, and the motor are not shown in the figure.

Next, as shown in step 62 of FIG. 1, the bamboo sheet tatami body 10 in FIG. 2 is turned over so that the bottom cloth 101 becomes the uppermost layer, and the bamboo sheet stacked table 103 becomes the lowermost layer, as shown in FIG. 3.

Next, as shown in step 63 and FIG. 3 of FIG. 1, the tatami body 10 is fed from the front to the back. In this embodiment, during the sewing process, the edge banding device 4 (commonly known as the bell mouth) is used to cover the edge band 3 on one side of the bamboo tatami body 10 to be sewn, and at the same time The sewing machine 2 is used to sew the side to be sewn so that the needle 21 of the sewing machine 2 sequentially passes through the edging belt 3, the bottom fabric 101, the stacked bed 102, the Bamboo sheet stacking table 103, and the edging band 3, wherein the motor provides the power required for the needle 21 to move up and down and the bobbin case to rotate, so that the upper and lower threads intersect to form the edging band 3, the bottom The stitches of the cloth 101, the stacked bed and the bamboo sheet are sewn together. After the stitches sew the edge band 3 and the bamboo tatami body 10 together to form a bamboo tatami 1 with a cloth edge 104, the bamboo tatami 1 continues to move backward and leans on the carrying platform 5 .

In more detail, in this embodiment, since the hemming device 4 is in the shape of a bell mouth, when the hemming tape 3 passes the hemming device 4 from front to back, the hemming tape 3 will be hemmed The device 4 is automatically bent into a "ㄈ" shape, that is, the edge band 3 after passing through the edge device 4 will have an upper horizontal portion 31 and a lower horizontal portion 32, and step 63 is mainly to make the needle 21 of the sewing machine 2 During the downward movement, it first penetrates the upper horizontal portion 31, then the bottom fabric 101, then the stacked bed 102, then the bamboo sheet stacking table 103, and finally the lower horizontal portion 32. Therefore, in the manufacturing method of the bamboo tatami of the present invention, since the bamboo tatami body 10 is first turned upside down, and then the selvage 104 is sewn, the cloth 101 on the bottom is on top and the bamboo sheet stacking table 103 is on the bottom In the case of, it will not cause the bamboo sheet stacking table 103 to break easily due to lack of support force, and there will be no problem of broken needles.

In summary, since the manufacturing method of the bamboo tatami of the present invention includes the step 62 of turning the bamboo tatami body 10 upside down first, the fabric edge is sewn when the bottom fabric 101 is on and the bamboo sheet stacking table 103 is down. 104, so it will not cause the bamboo sheet stacking table 103 to break easily due to lack of supporting force, and there will be no problem of broken needles, so it can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention, and the scope of implementation of the present invention cannot be limited by this, any simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still classified as Within the scope of the invention patent.
