Description

Cutting machine for vertical blind}

The present invention relates to a cutting machine for cutting the fabric, more specifically, it is possible to clean the cutting of the cut edges using ultrasonic waves, and is carried out by a single device from the fabric itself to the production of the production process reduction and production efficiency It relates to a cutting machine for cutting vertical blender fabric.

In general, fabrics made of natural fibers or synthetic fibers are manufactured to have a constant width and length when manufactured by a fiber company. The fabric is generally used by the consumer to cut to suit the purpose. In particular, vertical blenders, which are recently used for curtains, have a width of about 90 mm. In order to cut a certain fabric, conventionally, a person artificially performs the scissors through the scissors. As described above, the cutting work performed by the manual scissors is not only reduced in precision but also lowered in work efficiency, thereby increasing production cost. And the quality of the product is lowered.

Therefore, a cutting machine that automatically cuts the fabric to solve this problem is currently on the market. This cutting machine has a lot of problems, although the fabric is automatically cut to improve the precision and production efficiency of the product compared to the manual work.

First, there is a problem that can not perform any process from the fabric itself to the production of the product by the cutting machine itself, the degradation of product production efficiency and the accuracy of the product falls. In other words, in the case of a vertical blender, the width of the final product is about 90 mm, while the supplied fabric is usually 1 m or more in width. However, there is only one or two cutting parts of a vertically used vertical blender fabric cutting machine. Therefore, the fabric itself can not be made directly from the cutting machine to the required product, it is necessary to cut the fabric in advance to have a separate operation to have a width that can be produced in the cutting machine.

To describe this in more detail, for example, when the width of the fabric itself is 2m and the cutting parts are two, the fabric having a width of 2m is cut to a width of about 270mm in advance, and the cut fabric is injected into the cutting machine. Three vertical blender fabrics with a width of 90 mm will be manufactured. Therefore, the inconvenience of having to go through the operation of cutting the fabric to a certain size in advance, as well as the efficiency of the product production is degraded due to the failure during the cutting of the fabric.

In addition, in the conventional cutting machine, the product produced is not clean because the edge of the cut fabric for the blender is not easily cleaned, there is a problem that a separate finishing process should be made to prevent this.

That is, as shown in Figure 1, usually the fabric (1) is fine fibers are woven vertically and woven. When such fibers are cut by a cutting machine, the horizontal and vertical fiber yarns 1a constituting the fibers are exposed as they are, and as time passes, the fiber yarns 1a are untwisted and dirty. Therefore, in order to prevent the loosening of the fiber yarn (1a) of the edge portion must be a separate finishing treatment, which is performed by a separate process has a problem of lowering the work efficiency and rise in production cost.

Accordingly, the present invention has been made to solve the above problems, an object of the present invention is to provide a vertical cutting machine for cutting the vertical blender to produce a vertical blind by the cutting machine itself without a separate fabric cutting operation.

In addition, another object of the present invention is to provide a cutting machine for cutting the vertical blender fabric to improve the productivity and the work efficiency because the finishing treatment is performed at the same time as the cutting in the cutting machine is not finished.

In addition, the ironing portion is made to vary in temperature (0 ℃-230 ℃) according to the fabric weaving form and coating degree, the cutting fabric separation portion is divided by a plurality of ribs on the outer surface on the same axis separated into a plurality of cut It is preferable to be composed of a separator and a plurality of collection rolls for collecting each cutting fabric separated by the separator separately.

Therefore, the cutting and finishing processing of the fabric is made at the same time by the ultrasonic wave generating unit and the fabric cutting unit, and also has a number of advantages can be produced directly from the fabric itself without a separate fabric cutting work.

In addition, there is another advantage that does not require a separate ironing process by the ironing unit.

Next, with reference to the drawings showing a preferred embodiment of a vertical cutting machine for cutting the vertical blender according to the present invention having the technical configuration as described above will be described in more detail.

Figure 2 shows a schematic configuration of a fabric cutting machine according to the present invention, Figure 3 is a schematic side view showing the main components inside. As shown, the fabric cutting machine 10 according to the present invention, the fabric axis 20, the ultrasonic fabrication unit 30, the fabric cutting unit 40, the ironing unit 50 and the cutting fabric is largely wound fabric It consists of a separation unit 60. And, one side of the front of the main body is provided with various function buttons (12). The user operates the cutting machine by operating the function button 12.

First, the distal axis 20 will be described. The distal end shaft 20 is installed on one side of the lower part of the main body of the cutting machine, it is made of a structure that is separated and coupled. Therefore, the fabric shaft 20 is wound around the fabric to be cut to have a certain width (usually about 2m) and length. Then, two conveying rolls 22 and one conveying roll 24 are provided at the lower portion of the distal shaft 20, which are unfolded by applying a constant tension to the dispensing material supplied through the distal shaft 20. It is to be able to supply to. Therefore, the fabric supplied from the distal shaft 20 crosses the lower roll 22 and passes through the upper roll 24 to be flattened, so that the ultrasonic generator 30 and the fabric cutting unit 40 will be described later. It passes through.

Next, the ultrasonic generator 30 will be described. 3 and 4, the ultrasonic generator 30 is an apparatus for generating ultrasonic waves by the power supplied. The ultrasonic generator 30 is provided in a plurality of side by side on the upper side of the cutting machine, in this embodiment has a structure that is installed 21. In addition, the distance between each of the ultrasonic generators 30 maintains the distance as much as the width of the blender to be cut, and in this embodiment, maintains a distance of about 90 mm which is most commonly used as the width of the blender. Do it. Therefore, the fabric passing through the upper surface 32 of the ultrasonic generator 30 is cut into 20 fabrics having a width of 90 mm.

In addition, a worm gear 34 is formed at one side of each of the ultrasonic generators 30, and a rotation shaft 36 having a worm gear 34 and a gear 36a to be tasted is installed. Therefore, as the rotary shaft 36 is rotated by the power of the motor, the ultrasonic generator 30 can rotate horizontally in accordance with the rotation of the gear 36a of the rotary shaft 36 and the worm gear 34 to be tasted. do. The reason for allowing the ultrasonic generator 30 to rotate horizontally as described above is to prevent wear of the upper surface 32 of the ultrasonic generator 30. That is, during operation, ultrasonic waves are generated through the upper surface 32 of the ultrasonic generator 30, and the blade member 42 of the distal cutting unit 40, which will be described later, is the upper surface 32 of the ultrasonic generator 30. Because it is in contact with the blade 42 is not rotated because only the same part because it is in contact with only a specific part is easily worn to prevent this.

Next, the fabric cutting unit 40 will be described. As shown in Figure 4 and 5, the far-end cutting portion 40 is located on the upper portion of each of the ultrasonic generator 30 described above, it is made of a circular shape. A blade member 42 is formed at the center portion of the distal cutting portion 40, and a sawtooth-shaped crimping member 44 is formed at both sides of the blade member 42. And, the far-end cutting portion 40 is to be rotated in the vertical direction by the power transmitted. That is, the shaft 46 extends through the side central portion of each distal cutting machine, and the chain 46a is connected to the shaft 47. The chain 46a is connected to a separate rotation shaft 48 so that the power transmitted as the rotation shaft 48 is rotated allows each distal cutting portion 40 to be rotated in the vertical direction by the chain 46a. .

In addition, the fabric supplied by the distal axis 20 between the upper surface 32 of the ultrasonic wave generation unit 30 and the surface of the distal cutting unit 40 passes through the cutting. As shown in FIG. 4, the ultrasonic generator 30 is rotated horizontally in the left and right directions on the drawing, and the fabric cutter 40 is vertically rotated so that the supplied fabric is supplied with the blade member 42. It is cut by the ultrasonic waves, and moved to the rear side. In addition, as described above, since the ultrasonic generator 30 is rotated horizontally and evenly contacted with the blade member 42 of the fabric cutting portion 40 it is possible to prevent wear of any particular site.

On the other hand, the fabric cutting unit 40 according to the present invention is to be fused and fused at the same time so that each fiber yarn located at the edge of the fabric to be cut is not released. Hereinafter, this structure will be described with reference to FIG. 6. As shown, the fabric cutting portion 40 according to the present invention is provided with a blade member 42 in the center portion and a pressing member 44 made of a sawtooth shape on both sides. The blade member 42 is symmetrically inclined to both sides at the vertex of the end, and the inclination angle α is about 5 ° to 15 ° based on the horizontal plane. The reason for maintaining a gentle inclination angle as described above is that the side surface 42a is in contact with the edge of the cutting fabric so that the edge portion is fused by ultrasonic waves. That is, the fabric usually maintains a thickness of about 1mm to 2mm. While the sharp end of the blade member 42 cuts the fabric, the fabric is compressed, and the edge portion of the blade member 42 is in contact with both sides 42a of the blade member 42. Therefore, the edge of the cut out fabric by the ultrasonic wave generated from the side 42a of the blade member 42 and the ultrasonic generator 30 can be fused.

On the other hand, both sides of the blade member 42 is provided with a toothed pressing member 44. Therefore, while the edge portion is fused at the same time as the cutting by the blade member 42, the embossing operation is made on both sides of the cutting fabric by the pressing member 44. That is, the pressing member 44 presses the fabric, and the area where the sawtooth pressing member 44 is contacted by the ultrasonic wave applied by the ultrasonic generator 30 is embossed to make the edge of the cutting fabric It can be more and more protected. Therefore, after cutting fabric work, both edges of the produced blender is more clean finish, and does not need to add a separate finishing treatment.

Then, the cutting fabric passing through the ultrasonic generator 30 and the fabric cutting unit 40 passes through the ironing unit 50. As shown in FIG. 2, the ironing unit 50 is positioned behind the ultrasonic generator 30 and the fabric cutting unit 40 and is for ironing the cut fabric. The ironing part 50 is heated by a temperature-variable set point according to the fabric weaving form and coating degree by far infrared heater heating (0 ° C. to 230 ° C.) to remove the wrinkles by ironing the cut fabric.

At the rear of the ironing unit 50, a cutting fabric separation unit 60 for collecting the ironed cutting fabric is installed as a separate device. As illustrated in FIG. 7, the cutting fabric separation unit 60 may include a separator 62 separating a plurality of cut fabrics and a plurality of cutting fabrics separated by the separator 62. It consists of a collection roll 64 provided with two collection parts. The separator 62 has a plurality of outward ribs 62a formed on the same axis so that the ironed cutting fabric is wound on the outer surface of the separator 62 partitioned by the ribs 62a. Then, the cutting fabric wound on the separator 62 is wound by the collection roll 64, respectively, the user is to produce a vertical blender by using each of the individual collection roll (64).

That is, the individual collection rolls 64 are installed in a row on the same axis to rotate, and the cutting fabric is wound as the individual collection rolls 64 are rotated by the rotation of the rotating shaft. After being wound up, the rotating side is separated, and each separate collection roll is separated to form a fabric for a blender having a predetermined width.

Next will be described the overall operation of the vertical cutting machine for cutting the vertical blender according to the present invention configured as described above.

First, the material fabric is installed on the far end shaft 20. After the fabric shaft 20 is installed, the fabric is released and the fabric is placed between the upper surface and the lower surface of the fabric cutting portion 40 via the transfer rolls 22 and 24, and the finishing portion 50 is formed. To be connected to the cutting fabric separation unit 60 through. After the installation work of the fabric as described above, by operating the function operation button 12 located on the front of the main body to operate the cutting machine. That is, after the main power is turned on, the iron generator is turned on to operate the ultrasonic generator 30 in a state in which the appropriate temperature (0 ° C to 230 ° C) is maintained according to the state of the input fabric. .

In the above state, the fabric cutting unit 40 is operated to perform cutting of the fabric. The cutting operation of the fabric is performed according to the operation of the cutting machine, and the cut fabric is simultaneously ironed by the ironing part 50 while being transported, and the cut cutting fabric is separated from the cutting fabric separation unit 60 ( It passes through 62 and is wound on the collection roll 64. At this time, the fabric is cut to the size of the blender width while passing through the ultrasonic generator 30 and the fabric cut portion 40, at the same time the blade member 42 and the pressing member 44 of the fabric cut portion 40 The edge of the cutting fabric cut by) is fused and embossed at the same time, so no separate finishing of the edge is required. In addition, the cut cutting fabric is ironed through the ironing unit 50 and the ironing is carried out at the same time to be wound on each individual collection roll 64 so that no separate ironing operation and collection operation is required.

After the cutting work of the fabric is finished as described above, the user stops the power of the ultrasonic generator 30 and the fabric cutting unit 40 (off), and also the power of the ironing unit 50 (off). Then, the motor is stopped in the state in which the cutting fabric is wound around the collecting roll 64, and the uncut portion is removed at the distal end of the fabric. After separating the collection roll 64, a vertical blender is manufactured using the fabric for the blender wound on each collection roll 64.

As described above, according to the present invention, since the fabric itself is used without a separate fabric cutting operation, and a plurality of ultrasonic generators and fabric cutting portions are provided, the cutting fabric for the blender can be produced at the same time by cutting directly from the fabric, thereby improving productivity. There is an effect to be improved.

In addition, since the fusion and embossing of the edge of the cutting fabric is performed simultaneously with the cutting by the blade member and the pressing member of the ultrasonic generator and the fabric cutting portion, the finishing of the edge is not necessary, and the edge is long Another effect is that the fiber yarns do not loosen when used.

In addition, since the ironing is performed at the same time as the cutting operation of the fabric, the fabric work for the blender proceeds more smoothly, there is an advantage that can produce a clean cutting fabric.

On the other hand, since the collection operation of the cutting fabric for the blender in the fabric is made in one cutting machine, there is no need for a separate attachment device, and there is also an advantage of improving productivity and reducing manufacturing costs.
