Figure 3 or Figure 4 shows the calculation step (S1) of the method for forming a three-dimensional laminate on the fabric according to the present invention, the shape of the modeling (1) shown in Figure 3 is a cube to facilitate understanding Although illustrated and illustrated, it may be a polyhedron, a cylinder, a sphere, or the like having a three-dimensional shape, and there is no limitation on the shape.

In operation S1, the input modeling (1) data is divided into a plurality of vertical layer data (2) having a predetermined width (2L) as shown in FIG. 3.

In addition, the width 2L of the vertical layer data is preset according to the width of the resin extruded and laminated by the nozzle.

For example, when the maximum width of the resin that can be extruded through the nozzle is 1 mm, the width 2L of the vertical layer data is preset to 1 mm.

The modeling (1) data input as described above is divided into a plurality of vertical layer data (2) by a predetermined width (2L), and then divided into a plurality of horizontal layer data (31 to 36) as shown in FIG. Will proceed.

Accordingly, each vertical layer data 2 is composed of a plurality of horizontal layer data 31 to 36, such as 31A to 36A and 31B to 36B, and height 31H of the plurality of horizontal layer data 31 to 36. 36H) may be different depending on the height setting value for each position of the preset horizontal layer data.

For example, the height 31H of the horizontal layer data 31 located at the bottom may be preset to be 10 μm, and the height 32H to 36H of the other horizontal layer data may be preset to be 1 mm.

In addition, the divided plurality of horizontal layer data 31 to 36 may be designated as a plurality of sections 21 to 24 at predetermined vertical intervals from the lower side according to the laminated material (adhesive, first resin, and second resin).

For example, among the input modeling data, the first section used for laminating the adhesive, the second section used for laminating the first resin, the third section used for laminating the third resin, and the fourth resin may be used. It is specified by dividing into a fourth section used for stacking, and the setting of the section and the setting of the material are set when the modeling data is input.

In addition, the plurality of horizontal layer data 31 to 36 are designated as the plurality of sections 21 to 24 at predetermined vertical intervals from the lower side according to the stacking material (adhesive, first resin, and second resin).

With the designation of the plurality of sections 21 to 24 specified as described above, the calculation step S1 is completed, and an adhesive spraying step S2 and a first layer laminating step of laminating an adhesive and a plurality of layers on top of the fabric ( S11) is as follows.

Figure 5 shows the adhesive spraying step (S2) of the method for forming a three-dimensional laminate on the fabric according to the present invention, the adhesive spraying step (S2) is supplied and transported to the top of the stopped fabric (5) The adhesive is sprayed onto the fabric 5 at a predetermined width 2L in a shape corresponding to the divided modeling data of the first section located at the bottom of the horizontal layer data divided through the operation step S1.

In addition, the adhesive nozzle portion (described in more detail below) is transferred in the X-axis direction, and the first row 31A is laminated in the longitudinal direction on the top of the fabric 5.

When the first row 31A of the adhesive is laminated, the fabric 5 is repeatedly stacked in a manner of transferring the fabric 5 by a length corresponding to a predetermined width 2L in the Y-axis direction and laminating the second row 31B. The adhesive layer 10 is formed by spraying the adhesive onto the fabric 5 in a shape corresponding to the first section of the divided modeling data.

6 illustrates a first layer lamination step S11 of a method for forming a three-dimensional laminate on a fabric according to the present invention, wherein the first layer lamination step S11 is supplied and conveyed to the fabric 5. When the operation is stopped, the first resin melted in a shape corresponding to the modeling data of the second section of the horizontal layer data divided through the operation step S1 on the adhesive layer 10 formed through the adhesive spraying step S2. Is laminated in a predetermined shape to form the first layer 11.

In addition, while transferring the first layer nozzle unit (described in more detail below) in the X-axis direction, the

first rows

32A and 33A are stacked in the longitudinal direction on the adhesive layer 10.

For example, as shown in the drawing, when the

first columns

32A and 33A are divided into two horizontal layer data, the

first columns

32A and 33A are stacked along a stacking path as shown in FIG. 4.

When the

first rows

32A and 33A of the first layer 11 are stacked, the fabric 5 is transferred by a length corresponding to a predetermined width 2L in the Y-axis direction and the second rows are stacked. The first layer 11 is formed by stacking the first resin in a shape corresponding to the second section of the divided modeling data by repeatedly stacking the layers.

As described above, the fabric is stacked vertically from the

first rows

32A and 33A of the first layer and then stacked in the second row (32B and 33B) and the third row (not shown and 32C and 33C). The error of the stacking position caused by the elasticity generated at the time of transfer of (5) can be greatly reduced.

For example, according to the conventional laminating method of laminating the first layer consisting of three columns and two horizontal layer data horizontally and then laminating the next layer as described above, the first layer 32A from the lower first column 32A 2 rows (not shown, 32B), 3rd row (not shown, 32C), and then stacked again in the first row (33A) to the second row (33B), the third row (not shown, 33C) Lamination in order.

That is, in the conventional horizontal lamination method, as the number of horizontal layer data increases, the number of transfers of the fabric 5 increases more, and the more frequent the transfer of the fabric 5, the more poor the stacking due to an error due to the elasticity of the fabric. It happens frequently.

On the other hand, the method and apparatus for forming a three-dimensional laminate on the fabric according to the present invention is to reduce the transfer of the fabric (5) to a minimum to obtain the effect of preventing the failure due to the elasticity of the fabric (5).

In addition, when there is a third section and a fourth section, and the like, the second resin is formed on the first layer 11 through the second layer stacking step S21 in the same manner as the first layer stacking step S11 described above. To form a second layer 22 by laminating the third layer by laminating a third resin on top of the second layer 12 through the third layer lamination step S31. Iteratively performed for to complete the formation of the shape of the same shape as the input modeling data as shown in Figure 7 on the top of the fabric (5).
