DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a fabric cutting apparatus and a fabric cutting method according to the present invention will be described in detail with reference to the accompanying drawings. However, it should be understood that the present invention is not limited to the disclosed embodiments, but may be implemented in various forms, and the present embodiments are not intended to be exhaustive or to limit the scope of the invention to those skilled in the art. It is provided to let you know completely. The shape and the like of the elements in the drawings may be exaggerated for clarity, and the same reference numerals denote the same elements in the drawings.

FIG. 2 is a perspective view showing a fabric cutting apparatus according to the present embodiment, and FIG. 3 is a sectional view cut along the line III-III 'shown in FIG. 2 according to the present embodiment.

2 and 3, the fabric cutting apparatus 100 according to the present embodiment includes a support 110, a compression unit 120, a transfer unit 130, a cutting unit 140, a sealing unit 150, And a link portion 160 (see Fig. 4).

First, a plurality of stacked fabric 10 (hereinafter, referred to as a fabric) and a cover 30 are sequentially placed on the support 110. At this time, the cover 30 disposed on the upper side of the fabric 10 may be made of a transparent resin such as vinyl or the like having a larger area than the fabric 10.

The support 110 may include a plate 111 and a plurality of frames 113. The plate 111 allows the fabric 10 and the cover 30 to be supported flat. The plurality of frames 113 are disposed below the plate 111 to support the plate 111. [

The cover 10 is supported on the plate 111 and the cover 30 having a larger area than the fabric 10 is seated on the fabric 10 so that the upper surface of the plate 111 and the upper surface of the cover 30 A predetermined space defined by the fabric 10 is formed between the lower surface and the lower surface. Here, the compression unit 120 exhausts the space between the plate 111 and the cover 30 so that the fabric 10 is compressed.

The compression section 120 includes a vacuum pump 121 and a control valve 123.

The vacuum pump 121 is connected to a plurality of exhaust holes 111a formed in the plate 111. The vacuum pump 121 exhausts the space formed between the plate 111 and the cover 30 through the exhaust hole 111a so that the raw material 10 and the cover 30 are brought into close contact with each other on the plate 111. [ At this time, the raw fabric 10 is compressed between the plate 111 and the cover 30 by the pressing force of the cover 30 which is closely attached to the plate 111. And the control valve 123 may be disposed between the exhaust hole 111a and the vacuum pump 121. [ The control valve 123 controls the exhaust force applied between the plate 111 and the cover 30 from the vacuum pump.

The transfer unit 130 transfers the cutting unit 140 and the sealing unit 150 from the upper side of the plate 111 in a plane. The transfer unit 130 includes first and second linear actuators 131 and 133.

The first linear actuator 131 may be disposed outside the plate 111. The first linear actuator 131 transfers the second linear actuator 133 connected to the upper side in the x-axis direction. The second linear actuator 133 transfers the cutting portion 140 connected to one side in the y-axis direction. Here, the first and second linear actuators 131 and 133 may be implemented by a combination of a rack and pinion, a combination of a linear guide and a linear motor, and a hydraulic / pneumatic cylinder.

On the other hand, the cutting unit 140 is supported by the second linear actuator 133 so as to be rotatable in a plane direction with respect to the plate 111. The sealing portion 150 is connected to one side of the cutting portion 140 (see FIG. 4). Thus, the sealing portion 150 can be transported together with the cutting portion 140. Here, since the cutting unit 140 can be understood by a known technique, a detailed description thereof will be omitted. Hereinafter, the sealing unit 150 will be described in detail.

FIG. 4 is a perspective view showing a connection structure between the cutting part and the sealing part according to the present embodiment, and FIG. 5 is a sectional view taken along the line V-V 'shown in FIG.

4 and 5, the cutting part 140 and the sealing part 150 according to the present embodiment are connected by the link part 160. [

The link portion 160 may include first and second links 161 and 163 and a link pin 165.

The first link 161 is provided at the rear of the cutting unit 140 with respect to the feeding direction of the cutting unit 140. The second link 163 is provided at the top of the sealing portion 150 facing the rear of the cutting portion 140. The first and second links 161 and 163 are coupled by the link pins 165 so that the sealing portion 150 is transported together with the cutting portion 140 at the rear of the cutting portion 140, As shown in Fig.

The sealing portion 150 may include a main body 151, a reel 152, a guide roller 153, a pressure roller 154, a pressure roller support 155, and a feed cutter 156.

The main body 151 forms an outer shape of the sealing part 150 and the second link 163 is coupled to the top of the main body 151. A sealing member 50 provided in a roll shape is disposed inside the main body 151. The sealing member 50 is wound on a reel 152 disposed inside the main body 151. The sealing member 50 may be drawn out to the outside of the main body 151 through the outlet 151a opened downward of the main body 151 and supplied to the open area.

Here, the sealing member 50 may be a film or a tape coated with a pressure-sensitive adhesive on one side. It can be adsorbed on the open area by the evacuation force of the vacuum pump 121 which exhausts the space between the plate 111 and the cover 30 when the sealing member 50 is provided with a film. Further, when the sealing member 50 is provided with a tape, it can be more firmly adsorbed on the open area based on the evacuation force of the vacuum pump 121 and the adhesive force of the pressure-sensitive adhesive.

On the other hand, the guide roller 153 is disposed on the main body 151 to guide the drawing of the sealing member 50. That is, the guide roller 153 can be disposed adjacent to the outlet 151a. The guide roller 153 guides the sealing member 50 from the reel 152 to the open area. The guide roller 153 prevents the drawn-out sealing member 50 from coming into contact with the main body 151, thereby preventing the sealing member 50 from being damaged by friction.

On the other hand, the pressure roller 154 is supported by the pressure roller support base 155 below the main body 151. The pressure roller 154 presses the sealing member 50 drawn out to the lower side of the main body 151. Here, the pressure roller support table 155 supporting the pressure roller 154 can slide and expand and contract when the pressure roller 154 presses the sealing member 50.

The pressure roller support base 155 may include a buoyant portion 155a, a movable portion 155b, and an elastic body 155c.

The boot portion 155a is provided on the lower surface of the main body 151. [ The buoyant portion 155a has a space in which an upper end of the movable portion 155b is inserted and can be moved up and down. A support step is provided at the lower end of the floating part 155a to prevent the upper end of the movable part 155b from being separated from the floating part 155a. The upper end of the movable portion 155b is inserted and supported within the movable portion 155a. Thus, the movable portion 155b can be moved up and down toward the inner space of the braking portion 155a, and the pressing roller 154 supported on the lower side can be moved up and down. The elastic body 155c is disposed around the movable portion 155b between the blowing portion 155a and the pressure roller 154. [ The elastic body 155c generates a repulsive force between the blowing portion 155a and the pressure roller 154. [

Accordingly, the movable portion 155b can be lifted by the stress provided from the pressure roller 154, or can be lowered by repulsive force provided from the elastic body 155c.

Therefore, when the pressure roller 154 presses the sealing member 50, the pressure roller support 155 can lift the pressure along the curvature formed in the open area and buffer the stress applied from the pressure roller 154 to the open area .

On the other hand, the feed cutter 156 may include a cutter feed portion 156a and a cutter 156b.

The cutter feed portion 156a is provided on the lower side of the main body 151. [ The cutter feed portion 156a may be provided with a feed / pneumatic cylinder or a drive motor. The cutter transferring part 156a reciprocates the cutter 156b connected to one side between the guide roller 153 and the pressure roller 154 or moves the cutter 156b between the guide roller 153 and the pressure roller 154 . The sealing member 50 stretched between the pressing roller 154 and the guide roller 153 pressing the sealing member 50 in the open area can be cut and separated by the cutter 156b.

Thus, the sealing portion 150 closes the opening area of the cover 30 formed at the rear end of the cutting portion 140 at a position where the cutting portion 140 passes, in real time. Thus, the sealing portion 150 has an advantage that precise cutting of the fabric 10 is possible by preventing the fabric 10 from expanding and flowing through the open region.

Hereinafter, a method of cutting a fabric according to the present embodiment will be described in detail with reference to the accompanying drawings. In the following description, the detailed description of the components of the fabric cutting apparatus described above will be omitted, and the components not described in detail in the following description will be understood with reference to the above description.

FIG. 6 is a flowchart showing a method of cutting a fabric according to the present embodiment, and FIGS. 7 to 10 are process drawings showing a method of cutting a fabric according to the present embodiment.

As shown in Figs. 6 to 10, in the method of cutting a fabric according to the present embodiment, a plurality of fabric 10 and a cover 30 stacked on a plate 111 are seated (see Fig. 7). First, a plurality of fabrics 10 are seated on the plate 111 (S100). At this time, a predetermined pattern determined in the design process may be formed on the fabric 10. Thereafter, the cover 30 is disposed on the upper side of the fabric 10 (S200). The cover 30 may be made of transparent resin such as vinyl or the like having a wider area than the fabric 10. Thus, a predetermined pattern formed on the fabric 10 can be projected onto the cover 30. [

Thereafter, the cutting portion 140 and the sealing portion 150 are transferred to the upper side of one side of the raw fabric 10 where the initial cutting is started. At this time, the first linear actuator 131 feeds the cutting unit 140 in the x-axis direction, and the second linear actuator 133 feeds the cutting unit in the y-axis direction so that the cutting unit 140 moves from the upper side . One end of the sealing member 50 housed inside the sealing part 150 may be in a state of being drawn out from the sealing part 150 and disposed adjacent to the cover 30.

When the cutting part 140 and the sealing part 150 are transferred to the upper side of the raw material 30 where the cutting is started, the control valve 123 is opened and a vacuum pump 121 Exhausts the space between the plate 111 and the cover 30 through the exhaust holes 111a. The cloth 10 disposed between the plate 111 and the cover 30 is compressed between the plate 111 and the cover 30 by the urging force of the cover 30 closely attached to the plate 111 S300, Fig. 8). At this time, the control valve 123 is opened and closed, and the exhaust force applied between the plate 111 and the cover 30 can be controlled.

Thereafter, when the fabric 10 is compressed, the cutting unit 140 and the sealing unit 150 are transported together by the transport unit 130, and cutting and sealing can be performed in real time (see FIG. 9). At this time, the cutting portion 140 and the sealing portion 150 may be transported along a pattern formed on the fabric 10, or may be transported in a predetermined direction, and may perform cutting and sealing.

First, the cutting unit 140 is transferred and a cutting process is performed on the fabric 10 (S400). Thus, an open area is formed on the cover 30. [ The sealing part 150 to be transported along the rear of the cutting part 140 is freely rotated with respect to the cutting part 140 by the link part 160 and the opening part of the cover 30 formed by the cutting part 140 The region is sealed (S500). Here, one end of the sealing member 50 drawn out from the sealing portion 140 and disposed adjacent to the cover 30 can be adsorbed by the exhausting force of the vacuum pump 121 applied to the open region .

Thereafter, the sealing member 50 is drawn out from the sealing part 150 by the feeding of the cutting part 140 and the sealing part 150, and the open area formed in the place where the cutting part 140 passes is closed. At this time, the sealing member may be drawn out from the sealing portion 150 by a drive motor (not shown), or may be taken out along with the transfer of the sealing portion 150 in a state where one region of the sealing member is adsorbed to the open region.

And the pressure roller 154 is conveyed on the upper side of the open area and presses the sealing member 50. At this time, the pressure roller support base 155 is stretched along the curvature of the open area to prevent the cover 30 from flowing due to the stress applied from the pressure roller 154 to the cover 30. Thus, the fabric 10 is prevented from being scattered by the stress applied to the cover 30. [

Thereafter, when cutting of the fabric 10 is completed, the cutting unit 140 stops feeding and finishes cutting. At this time, the vacuum pump 121 may be in a stopped state in the space between the plate 111 and the cover 30. The cutter 156b is then conveyed by the cutter conveying portion 156a between the guide roller 153 and the pressure roller 154 and cuts the tensioned sealing member between the guide roller 153 and the pressure roller 154 (S600, 10). The cutting process for the cloth 10 can be completed.

Although the cutting unit 140 and the sealing unit 150 are separately provided and transported together in the present embodiment, the cutting unit 140 and the sealing unit 150 may be integrally formed. In addition, although the present embodiment describes that a plurality of stacked fabric 10 are disposed on the lower side of the cover 30, the cover 30 is provided in the form of a sealing member as shown in FIG. 1, The cloth 10 can be compressed while being accommodated inside the cover 30. [

Although the cutting portion 140 and the sealing portion 150 are simultaneously operated in the present embodiment, the cutting portion 140 and the sealing portion 150 may be individually driven have.

Therefore, in the fabric cutting apparatus and the fabric cutting method, the open area formed on the cover in the fabric cutting process is sealed in real time, and precise cutting can be performed on the fabric, thereby improving the quality of the fabric. In addition, the fabric cutting apparatus and the fabric cutting method have the effect of improving the productivity for fabric processing as a plurality of stacked fabrics are cut without being scattered.

One embodiment of the invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention as long as they are obvious to those skilled in the art.
