Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale and wherein like reference numerals in the various drawings refer to like elements.

1 is a perspective view showing a schematic overall structure of a fabric cutting apparatus of the present invention.

1, the fabric cutting apparatus of the present invention is located at the front end of a work panel 100 on which a cut target composed of a fabric is seated, A roller unit 200 composed of rollers 210 for rotating the roller unit 200 and a roller unit 210 for rotating the roller unit 200 to be discharged, A rotary grip 321 which is rotatable with respect to the stationary rod 310 in a state of being engaged with the rotary grip 321 so as to be able to move in the direction of the cutting object, A width cutting means 322 composed of a rotating housing 322 including a space and a circular blade 323 coupled to rotate in the inner space to cut the width of a cutting object; 200) of the rocker 340 And a moving line 411 extending in the width direction and spaced upward from the operation panel 100. The moving line 411 extends in the width direction of the operation panel 100, A length cutting unit 400 including a moving rail 410 including a rail 412 mounted on the rail 412 and a circular blade 323 coupled to the rail 412 to cut the length of the cutting object, A vise 600 for applying pressure to one side of the operation panel 100 so that the cutting target is not distorted and a controller 500 for controlling the driving of the width cutting unit 300, the length cutting unit 400 and the vise 600 ).

1, the direction in which the cutting target is initially put is referred to as a front end of the working panel 100, a direction in which the cutting target is discharged is referred to as a working panel 100, And a direction perpendicular to the longitudinal direction is referred to as a width direction (or horizontal direction). The direction in which the cutting object is inserted is referred to as a longitudinal direction (or vertical direction), and the direction perpendicular to the longitudinal direction is referred to as a width direction

First, the work panel 100 is the foundation of the fabric cutting apparatus, and the cutting target is placed on the upper surface of the work panel 100 and cut. Accordingly, the roller unit 200, the width cutting unit 300, the length cutting unit 400, and the vise 600 are positioned with respect to the operation panel 100, and the cutting target is put into the operation panel 100 Cut to the required size. In this case, since the roller unit 200, the width cutting unit 300, the length cutting unit 400, the vise 600 and the like are formed at a suitable height or position in the operation panel 100, The fabric cutting device can be formed.

The work panel 100 may also be constructed by adding related configurations to act as a kind of conveyor belt because the cut target inserted through the rollers 210 has a width cutter 300 and a length cutter 400 To be discharged from the fabric cutting device even after the cutter is cut to a certain width and length while passing through the conveyor belt.

1, the operation panel 100 is divided into specific areas according to its configuration. In the front area, there are a seating area for waiting for the cutting object to be fed into the roller unit 200, 200), a width cutting area where the width cutting unit 300 is positioned and cutting the cutting target with a predetermined width, a blade unit 600 in which the vise 600 is positioned or a roller unit A fixed region in which a fixed seating line 110 for fixing the circular blade 323 of the width cutting unit 300 is formed and a fixed region where the length cutting unit 400 is positioned, And a second roller region in which a roller unit 200 for discharging a cut target to be cut from the fabric cutting device is located. Of course, this is an example, and it is needless to say that a portion other than the width cutting area, the length cutting area, and the first roller area may be selectively added or removed.

Next, the roller 210 is positioned at the front end or the rear end of the operation panel 100, and allows the object to be cut toward the operation panel 100 or the object to be cut is ejected from the operation panel 100. The roller 210 closely contacts the upper or lower side of the cutting target and pushes the cutting target through the rotation to provide a moving force to be fed toward the working panel 100 or to be discharged from the working panel 100. The shape of the roller 210 is generally formed in a cylindrical shape corresponding to the width of the object to be cut. However, in order to reduce the manufacturing cost, a method of forming the roller 210 may be applied. In addition, The roller 210 may be used in combination with the two rollers 210 to prevent the rollers 210 from being cut. Also, the roller 210 can be positioned at the rear end of the work panel 100, which means the discharge direction. In this case, the cut target cut to a certain width and length is discharged from the fabric cutting device to the outside And the like.

The width cutting unit 300 cuts the cutting target moved through the roller unit 200, which is the rear of the roller 210 that feeds the cutting target, and cuts the cutting target put in through the roller 210 in the vertical direction will be. That is, the fixing bar 310 is formed in the 'n' shape extending from the side of the operation panel 100 and extending in the width direction of the operation panel 100 at a position spaced apart from the operation panel 100 And a pivoting grip 321 that is pivotable with respect to the pivot rod 310 in a state of being engaged with the pivot rod 310 is engaged. That is, the turning grip 321 is rotatable forward and backward with respect to the fixing rod 310, and the turning grip 321 may be moved along the fixing rod 310. In addition, it is needless to say that a rail, a pulley, or the like may be further attached to the mounting bar 310 so as to be automatically moved along the mounting bar 310.

A rotary housing 322 extending from one side of the rotary grip 321 and including an inner space partially opened in a direction toward the object to be cut and a rotary housing 322 coupled to rotate in the inner space to cut the width of the object to be cut The blade 323 is included. That is, the pivoting housing 322 has a circular blade 323 in its inner space and a pivoting grip 321 on its one side. The pivoting unit 322 is referred to as a width cutting means 320. In order to cut the object to be cut without cutting the circular blade 323 in the inner space, a rotation shaft which can be rotated while receiving the circular blade 323 is provided in the inner space of the rotation housing 322 and a motor And a power unit is included. In this case, it is needless to say that various motors such as a step motor and a servo motor can be applied as needed. The circular blade 323 is placed on the upper surface of the cutting target since the cutting target must be cut and the circular blade 323 The inner space of the rotation housing 322 must be partially opened in the direction in which the cutting object is positioned, and therefore, it is preferable that the opened direction is directed to the paper surface.

In addition, since the circular blade 323 can be cut only in the direction in which the saw blade is thin and the saw blade rotates, the circular blade 323 can be cut in a direction in which the cutting target is cut The circular blade 323 may be positioned so that the direction of rotation of the saw blade is the same direction as the longitudinal direction through which the object to be cut is inserted through the roller 210. [ Likewise, the circular blade 323 located in the next length cutting section 400 cuts the length of the cutting target, which must be cut in the width direction. In this case, the circular blade 323 may also be configured to be positioned so as to face the width direction which is a direction perpendicular to the direction in which the rotation direction of the saw blade is inserted through the roller 210. [

The circular blade 323 of the width cutting unit 300 is used to cut the width of the cutting target and the direction of rotation of the circular blade 323 is set to the direction of the roller 210, So as to be positioned in the same longitudinal direction as the direction in which the cutting target is inserted. Thereafter, as an operation for controlling the width for cutting, the manager moves the rotating housing 322 coupled to the fixing rod 310 along the fixing rod 310 via the turning grip 321 to cut the cutting target And a separate locker 340 is further provided so that the designated width is not changed after the width is specified.

The locker 340 is a locking device for applying a kind of frictional force. For example, the locker 340 is closely attached in a form of wrapping the fixing rod 310 like an Omega-shaped clamp to form a lock so as not to move through frictional force. And a clamp having an omega shape attached thereto for fixing the position thereof after the rotation grip 321 is moved or pivoted is hermetically attached to the fixing rod 310 and is tightened so as to be locked so as to prevent the rotation grip 321 ) Is no longer moving and it helps to hold the position.

When the roller unit 200 is driven after fixing the position of the rotation grip 321, the cut target inserted through the roller unit 200 is cut in the longitudinal direction (vertical direction) passing through the width cutting unit 300, Width.

Next, the length cutting unit 400 is positioned at one of a front end and a rear end of the width cutting unit 300, and is formed along the width direction of the operation panel 100 and is provided with a moving rail And a circular blade 323 connected to the moving housing 413 so as to be rotated by the rotational force of the motor and cutting the length of the cutting target, And a length cutting means (420).

The length cutting unit 400 is different from the width cutting unit 300 in that the circular blade 323 is rotated in the width direction (horizontal direction) to cut the length of the cutting target, And a rail provided on the movement line 411 extending along the width direction so as to reciprocate along the width direction of the operation panel 100. [ (412) is used as the movable rail (410).

The moving rail 410 is constructed using a known rail 412 configuration and forms a moving line 411 along the position and direction in which the circular blade 323 is to be moved and a rail 412 ). The moving rail 410 is similar to the fixing rod 310 of the preceding width cutting unit 300 except that a locking slot or an insertion space is further formed and a circular blade 323 is inserted into the locking slot or the recessed space And the included moving housing is coupled to the moving rail 410 and reciprocates in the width direction along the rail 412. However, the movable rail 410 may be configured to include a known rack-pinion structure, a pulley-chain structure, a motor for providing power, and the like so that the movable housing can be automatically reciprocated. More specifically, It is omitted.

The movable housing 413 has a shape of 'n', and a recessed portion (not shown) corresponding to the movable rail 410 is formed at the recessed portion of the movable housing 413, 410, the locking protrusion is engaged with the movable rail 410 and moves. At this time, the pulleys are provided on both sides of the moving rail 410, and pulleys for providing a driving force for moving the pulleys in the width direction by a chain or the like are applied. Alternatively, the moving rail 410 can be moved in the width direction Method and the like can be utilized. That is, the movable housing 413 corresponds to the pulley type or the sliding type of the movable rail 410 and receives the driving force from the pulley type or the sliding type of the movable rail 410. The movable housing 413 is provided with a length cutting means 420, which is a combination of the movable housing 413 and the circular blade 323 In the width direction of the movable rail 410.

That is, the cut target inserted through the roller unit 200 is cut in the width direction passing through the length cutting unit 400. Therefore, in order to facilitate the movement of the cutting target inside the fabric cutting apparatus, it is preferable to discharge the cut through the length cutting unit 400 after passing through the cutting unit 300. However, in the above description, If the fabric cutting device is constructed to have the same structure or to allow the cut target to be sufficiently moved, there is no serious problem even if the length cutting unit 400 is positioned ahead of the width cutting unit 300.

Next, the vise 600 is positioned on at least one side of the operation panel 100, and pressure is applied so that the cutting target is not twisted, and the vise 600 is fixed in a state of being put in the cutting process. The vice 600 may have a variety of configurations, such as a pair of vice 600, a single vice 600, or three or more vice 600. In the case of using at least two vices 600, it is possible to fix the position where the cutting target is put by pressing the bar 600 in the opposite direction by facing each other, Or by applying a force from the top surface toward the bottom surface. Such a vice 600 can be formed in various forms, which will be described in more detail in the following sections.

The controller 500 controls the driving of the width cutting unit 300, the length cutting unit 400 and the vise 600 and may be included in the fabric cutting apparatus or may be formed as an external control box or the like. This will also be explained in more detail in the following sensor configuration.

A cutting target composed of a fabric is cut in the longitudinal direction and in the longitudinal direction by a basic structure of the working panel 100, the roller 210, the width cutting unit 300, the length cutting unit 400, the vise 600, It is possible to form a fabric cutting apparatus capable of cutting in the width direction.

2 is an enlarged perspective view of the width cutting unit 300 in the fabric cutting apparatus of the present invention.

2, the locker 340 of the width cutting unit 300 is configured to surround the lock bar 310 so that the turning grip 321 is fixed to the lock bar 310, A locking hook 342 extending from both ends of the fixing clamp 341 and having an engaging groove formed at a central portion thereof and a fixing hook 342 extending from both ends of the fixing clamp 341, And a fastener 343 which passes through the locking hooks 342 in a fully retracted state.

The fixing clamp 341 is formed by rounding the mounting bar 310 so that the turning grip 321 is fixed to the mounting bar 310. The locker 340 is strongly fixed by locking the fastener 341 through the fastener 343 which passes through the lock hook 342 in a state in which the fastening clamp 341 is pulled in close contact with the lock bar 310 will be.

At least one penetrating groove is formed on the surface of the turning grip 321. At least one insertion groove is formed in the locker 340 at a position corresponding to the coupling groove, And a fastener 343 which penetrates and joins both the insertion groove and the coupling groove. That is, if the above-described configuration describes how the locker 340 is fixed around the mounting rod 310, this configuration describes how the rotation grip 321 and the locker 340 are fixed. In addition, if both of the above-described configurations are utilized, the position can be fixed through the joining structure of the front joining groove and the locking hook 342 after the turning grip 321 is moved left and right in the fixing bar 310, After the turning grip 321 is pivoted up and down in the fixing rod 310, the angle of rotation can be fixed through the coupling structure of the coupling groove and the insertion groove.

In addition, in the case where the width cutting unit 300 is rotated to the bottom surface at the maximum, when the turning housing 322 is rotated by the upper surface of the cutting target to cut the cutting target, the phenomenon of further tilting due to gravity The work panel 100 further includes a fixed seating line 110 positioned at the rear end of the width cutting unit 300 and extending in the width direction in a manner corresponding to the fixing bar 310, The rotation housing 322 further includes a fixing bar 324 that is mounted on the upper surface of the fixed seating line 110 in a state in which the width cutting means 320 is rotated by the upper surface of the object to be cut in order to cut the object to be cut .

That is, when the fixed seating line 110, which is the same as or similar to the fixed bar 310, is located at the rear end of the width cutting unit 300 and the turning housing 322 is lowered to the maximum to cut the cutting target, The fixing bar 324 extending from the rotation housing 322 is seated on the line 110 to prevent tilting due to gravity.

In the case of a simple seat, the pivoting housing 322 is effective in reducing the influence of gravity, but if the rotating blade rotates radially, there is a possibility that its position is gradually moved due to the occurrence of vibration. A plurality of air holes 111 are formed in the upper surface of the fixed seating line 110 so as to be threaded in the inner peripheral surface of the fixed seating line 110. At the upper surface of the fixing bar 324, And the width cutting means 320 further includes a lever 326 which penetrates through the hole 311 and the coupling hole 325 and joins the hole 325. The coupling hole 325 is formed in the inner peripheral surface of the through hole, . In other words, a plurality of air holes 111 are also formed in the fixed seating line 110. In this case, it is most preferable that the air hole 111 is punched in accordance with the width of the generally used cutting object. The lever 326 is similar to a kind of fastener 343 except that the lever 326 is not only for penetrating and engaging but also for adjusting the protruding length after engaging through the lever 326, There is also an effect that the line 110 can be seated or mounted at various heights. In addition, a scale line capable of serving as a holder for recognizing the actual length can be further formed on the fixed seating line 110, so that the width of the current width cutting means 320 can be confirmed by the actual value Of course.

The pivoting housing 322 is further provided with a through extension 327 through which the inner surface of the pivoting housing 322 is extended from the opposite side of the open space of the inner space of the pivoting housing 322 . The penetration extending portion 327 can serve as a kind of handle. By pulling the penetration extending portion 327, it is possible to forcibly control the width cutting means 320 to rotate up and down in the fixing rod 310 . As another example, cooling water may be contained in the penetration extension portion 327 to cool the heat generated by the long driving of the rotary blade. However, as a most preferred embodiment, the proximity alarm device 330 may be included in the perforated portion of the penetrating extension 327. [ The proximity alarm device 330 includes a gyroscope 331 for generating the rotation position information, a human body detection sensor 332 for sensing the proximity of the human body to generate human body detection information, and an alarm means 333 for generating an alarm sound, And an alarm unit including a sensor, which is a kind of a warning light having a sensor.

In addition, the controller 500 includes a slope determining unit 511 for determining whether the rotation housing 322 rotates by comparing the rotation position information with the predetermined reference rotation position information, and a tilt determining unit 511 for determining whether the tilt determining unit 511 rotates A proximity determination unit 512 for determining whether the human body is in proximity to the body of the rotation housing 322 by receiving the human body detection information and a proximity determination unit 512 for controlling the alarm unit to generate an alarm And an alarm generating unit 513.

The gyroscope 331 is a sensor for sensing the inclination of a point at which the gyroscope 331 is currently located. The human body sensor 332 detects the temperature, moisture, And senses the proximity of the human body when it is recognized as a human body. The alarm means 333 means a voice guidance means such as a light emitting means such as an LED or a speaker, and generates a notice that can be recognized by a user or an administrator located in the vicinity. The shape of the proximity alarm device 330 is similar to a kind of a screw, and includes a portion that is inserted into the through-hole extension portion 327 and a portion that protrudes to the outside and generates a sensing and an alarm.

  The controller 500 includes a tilt determining unit 511 for comparing the tilt position information and the predetermined reference tilt position information to determine whether the tilt rotation housing 322 rotates, A proximity judging unit 512 for judging whether the human body of the rotation housing 322 is in proximity to the human body by receiving the detection information and an alarm for controlling the alarm unit to generate an alarm And an alarm module 510 composed of a generator 513. That is, it can be compared with the reference rotation position information through the rotation position information to know the position of the rotation housing 322, so that it can be determined whether or not the rotation is possible. Here, the reference rotation position information is a reference for determining whether the rotation housing 322 is rotated. For example, if the maximum rotation position where the cutting target can be cut is stored and is referred to as reference rotation position information, When the rotation position information is larger than the reference rotation position information when compared with the rotation position information, it can be confirmed that the unconditioned cutting target is no longer cut.

The human body detection information can thereby know whether there is a user approaching the rotation housing 322 or not. Therefore, the human body detection information is additionally received only after the tilt determination unit 511 determines whether or not the tilt is determined, and it is determined whether the human body is in proximity to the tilt housing 322. [ Thereafter, the alarm generating unit 513 controls the alarm unit to generate an alarm when it is determined that the human body of the rotation housing 322 is in proximity.

For example, there may be a person who is close to the rotation housing 322 through the human body sensor 332 by designating the maximum rotation state as the maximum rotation state, The proximity distance is assumed to be 5 m or less. Assuming that the reference of human body proximity information is 7m, it is necessary to generate an alarm because the proximity distance is less than 5m. In this case, the alarm generating unit 513 controls whether or not an alarm is generated so that an alarm such as light shining or sound is generated in the alarm unit.

3 is a perspective view showing the vise 600 in the fabric cutting apparatus of the present invention.

The vise 600 includes a step motor 611 and a cylinder 612 reciprocally moved up and down by a driving force of the step motor 611. The vise 600 is reciprocated vertically in the cylinder 612, A piston 613 and a wheel portion 610 mounted on an end portion of the pushing piston 613 and including a wheel 614 rotated in contact with a cutting object.

The vise 600 is mounted on one side of the work panel 100, and more specifically, extends in a direction orthogonal to the upper surface of the cutting target or in a direction orthogonal to the side surface, and the piston reciprocates in the vertical or horizontal direction . However, in the drawings, the piston is configured to reciprocate in the vertical direction, and therefore, the description will be made with reference to the embodiment.

Specifically, the outer surface of the vise 600 is divided into a stepping motor 611 and a pushing piston 613 connected to each other via a cylinder 612. [ The step motor 611 provides a driving force for moving the cylinder 612 in the vertical direction, that is, up and down. The step motor 611 may be of any one of a pneumatic type and a hydraulic type in addition to the electric type.

The cylinder 612 performs up-and-down reciprocating motion by the driving force of the step motor 611 and is connected to the pushing piston 613. [ The cylinder 612 has a structure corresponding to a rectangular parallelepiped extending in the vertical direction and has a vertically opened state. Specifically, the cylinder 612 can reciprocate the pushing piston 613 in the opening direction.

The cylinder 612 may be attached to the operation panel 100 through adhesive means or a separate fixing means through one of the four sides of the cylinder 612. However, It is preferable that the opened face of the cylinder 612 is attached to the operation panel 100 or another fixing means in a state that one side of the cylinder 612 is open. At this time, it is of course possible to form a plurality of fastening holes at predetermined intervals by forming separate bent portions at both ends of the opening face, and to fasten the fastening holes through fasteners 343 such as bolts.

A pushing piston 613 is provided in the inner space of the cylinder 612 and reciprocates vertically along the inner wall of the cylinder 612 by the driving force of the stepping motor 611 so that the friction with the inner wall of the cylinder 612 A separate friction ring may be further provided on the pushing piston 613. [ That is, the driving force of the stepping motor 611 is transmitted to the pushing piston 613 to move the pushing piston 613 up and down. Even if the cutting target is thin, The surface may be convex or concave, and may be distorted during the cutting process. If cutting is done without applying force to the cutting target, there is a high probability that the width and length will come out at various times. Accordingly, the pushing piston 613 can be moved downward to contact the upper surface of the cutting target, and the pushing piston 613 pushes the upper surface of the cutting target, and the pressing action is such that the circular blade 323 It can be continued during the cutting process to prevent the cutting object from being repelled or unnecessary flow during the cutting process.

In addition, the vise 600 of the present invention is capable of including a wheel 614 at the end of the pushing piston 613. The wheel 610 is formed by forming a wheel 614 at the end of the pushing piston 613. The wheel 614 is brought into contact with the object to be cut so that even when the object to be cut is continuously inserted, It can prevent repulsion or unnecessary flow. The wheel 614 may rotate about an axis as a generally thought wheel, but as shown in FIG. 3, a round spherical wheel is fixed to the fixing portion such that it is used as a spice container or a water container, It can be formed so as to be able to proceed in any direction while rotating.

4 is a perspective view showing an embodiment of the wheel 610 in the fabric cutting apparatus of the present invention.

The wheel portion 610 according to Fig. 4 (a) includes a connecting portion 615, a wheel shaft 616, and a wheel 614 as another embodiment.

The connecting part 615 is a bar-shaped structure vertically extending at an end (lower end) of the pushing piston 613 and the wheel shaft 616 is extended vertically and horizontally at the end of the connecting part 615 Respectively. The wheel 614 is rotatably mounted to the end of the wheel shaft 616 via bearings and other configurations (such as bushes and snap rings), and may be constructed with one wheel shaft 616, It is more preferable that they are provided at both ends of the wheel shafts 616 so that they can be dispersed naturally and stably, resulting in two.

According to the wheel unit 610, when the pushing piston 613 presses the cutting target, the wheel unit 610 performs a function of preventing the cutting target from being separated or wrinkled due to friction between the circular blade 323 and the cutting target. In other words, since the wheel 614 can contact the cutting object and rotate naturally, the blade 614 can be pressed against the cutting target and the cutting object can be prevented from being separated or wrinkled due to the friction of the circular blade 323.

 In this process, the connecting part 615 may be formed of a spring so that the vise 600 can press the cutting object more flexibly. Further, the surface of the wheel 614 is detachably attached to the surface of the cutting blade 614 in consideration of the material and roughness of the cutting object. It is possible to further laminate the friction pads 617 as much as possible. The friction pad 617 has a plurality of frictional protrusions protruding in an embossed structure. The frictional protrusions are made of an elastic material to assist in the resilient pressing function.

4 (b), one end of the wheel 610 is provided with an elongated clamp 618 which is rounded to have a space in which the object to be cut is seated, A support plate 619 for supporting the lower surface of the object to be cut and a wheel 614 mounted on the support plate 619 and rotatably mounted thereon.

The extension clamp 618 is rounded so as to have a space in which one side of the cutting target is seated, which is taken into consideration that the vise 600 is coupled to one side of the operation panel 100. That is, the extension clamp 618 is additionally extended laterally from one side of the wheel 610, which is a constitution of the conventional vise 600, and is round-machined so that one side of the cutting target is rounded by the extension clamp 618 As shown in Fig. The supporting plate 619 and the wheel 614 which are provided on the supporting plate 619 and are rotatably mounted are disposed at the end of the rounding process of the elongated clamp 618, . Since the lower surface of the object to be cut is supported by the lower surface of the object to be cut by using the conventional pushing piston 613 in the case of the support plate 619, The distortion of the object can be further prevented. The wheel 614 is brought into close contact with the lower surface of the object to be cut so as to facilitate movement while applying pressure. That is, the stationary clamp 341 is further formed, and it is possible to prevent separation or wrinkling of the object to be cut by applying pressure to the upper surface as well as the lower surface of the object to be cut. In addition, a spring structure may be further added to the stationary clamp 341 so as to press the object to be cut at the upper and lower portions together with the pushing piston 613 to form a reliable fixing structure. In some of the inner surfaces of the stationary clamp 341, It is needless to say that a slot corresponding to the side surface of the object may be additionally formed so that the object to be cut is inserted into the slot and moved.

In addition, the pressure sensing sensor 620 and the motion sensing sensor 630 can be mounted on any one of the wheels 614 to 616, and the control by the controller 500 can be added in association with the pressure sensing sensor 620 and the motion sensing sensor 630 .

Specifically, the motion detection sensor 630 detects an acceleration and a motion locus (mainly vibration or not) caused by the movement or repulsion of the wheel 614, and preferably includes an acceleration sensor and a gyroscope 331 together. That is, the motion detection sensor 630 is used for grasping the change of the motion of the wheel 614, and is numerically quantized so that the acceleration of the wheel 614, the frequency of the wheel 614, and the specific motion state of the wheel 614 can be grasped And generates motion information based on the motion information.

Next, the pressure sensing sensor 620 measures the pressure applied to the wheel 614 when the wheel 614 contacts the cutting object. The pressure sensing sensor 620 serves to generate numerical pressure information so that the pressure of the wheel 614 can be grasped .

The controller 500 includes a reference control setting module 520 for receiving the reference pressure information and the reference motion information value from the manager based on the pressure information and the motion information and generating the reference information based on the pressure information and the motion information, And a vise control module 530 for controlling the stepping motor 611 in a differential manner to adjust the vertical moving distance of the pushing piston 613 according to the comparison width.

The reference control setting module 520 generates reference information by specifying reference values of the pressure information and the motion information. The vise control module 530 compares the pressure information and the motion information values on the basis of the reference information, And controls the driving of the stepping motor 611 in accordance with the width of the width to control the upward and downward movement distance of the pushing piston 613.

Here, the reference information means a threshold value for pressure or motion. For example, if the pressure is set to the A value and the vibration is set to the B value, 600, i.e., the height of the pushing piston 613 can be controlled. Through such differential control, the fabric cutting device is naturally compatible according to the type of the cutting object, thereby providing a characteristic that a more stable cutting environment can be pursued.

As described above, the configuration and operation of the fabric cutting apparatus according to the present invention are described in the above description and drawings, but the description of the present invention is not limited to the above description and drawings. It is to be understood that various changes and modifications may be made without departing from the spirit and scope of the invention.
