The terms used in this specification will be briefly described, and the present invention will be described in detail.

The terms used in the present invention have been selected from general terms that are currently widely used as much as possible while considering the functions in the present invention, but these may vary depending on the intention of a person skilled in the art or precedent, the emergence of new technologies, and the like. Therefore, the term used in the present invention should be defined based on the meaning of the term and the overall content of the present invention, not simply the name of the term.

Advantages and features of the present invention, and methods for achieving them, will become clear with reference to the embodiments described below in detail in conjunction with the accompanying drawings.

Referring to FIG. 1, the entire process of a sewing factory that produces products such as clothes is performed by wearing a first fabric, storing a second fabric, performing a third grinding operation if necessary, and performing a fourth cutting operation. After that, the fifth numbering operation is performed. At this time, the numbering operation is an operation necessary for manufacturing a finished product by marking a number or mark necessary for each cut fabric, that is, a piece of fabric. Thereafter, a plurality of fabric pieces are manufactured as one finished product through the sixth sewing machine operation. Thereafter, the seventh inspection operation is performed, the eighth packaging operation is performed, and the ninth product is released. In the prior art, as the fifth numbering operation was performed manually, there was a problem in that the error rate due to mistakes was high and the time required for the operation was very long. Therefore, in the present invention, the numbering operation is performed at the same time as the third grinding operation is performed, so that the finished fabric can be transferred to the cutting machine in a numbered state, and in this process, the numbering information file and the cutting cam (CAM) ) file, etc., so that important origin settings can be easily performed.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

Referring to FIGS. 2 and 3, in the system for setting the origin of a spreading machine according to a preferred embodiment of the present invention, a work table 300 on which a fabric is placed and provided on the top of the work table 300, It includes a pruning machine 200 that performs work, and the pruning machine 200 includes a rail part 265 provided in the transverse direction of the fabric placed on the work table 300, and the rail part 265 It includes a first adjusting unit 261 provided to be transportable along the first adjusting unit 261 and a second adjusting unit 262 provided to be transportable along the longitudinal direction of the first adjusting unit 261. The adjusting unit 261 is transferred so that the edges of the fabric coincide with each other, and the distance from the edge of the work table 300 to the edge of the fabric is measured, and the second adjusting unit 262 adjusts the unused area of the fabric. It is transferred to coincide with the boundary point, so that the distance from the edge of the fabric to the boundary point of the unused area of the fabric is measured, so that the edge of the damaged fabric that cannot be used for manufacturing clothes is prevented from being used for manufacturing clothes do.

The distance in the width direction of the fabric used in clothing manufacturing is formed in various ways, and it is essential to measure the distance in the width direction of the fabric to perform cutting, numbering, and cutting according to the distance in the width direction (transverse direction) of the fabric. However, since the edge portion of the normal fabric is damaged or has a hole, it cannot be used for manufacturing clothes or the like. That is, the unused area of the fabric means a portion that cannot be utilized for manufacturing clothing. In other words, when the cutting operation is performed after the straightening, if the edge portion of the fabric is used to manufacture clothes, there is a problem in that defective products are produced. Therefore, as the cutting operation origin P2 to be described later is formed at a point spaced inward from the edge of the fabric, that is, the boundary point of the unused area, the unused area constituting the edge of the fabric is not included in the numbering work and cutting work. is to do

In addition, the origin setting system of the grinding machine of the present invention further includes a control device 100 in which a dedicated input program for grinding and cutting is installed and generating plan information for grinding and cutting, 1 The distance measured through the adjusting unit 261 and the distance measured through the second adjusting unit 262 are input to the controller 500 to be described later, respectively, so that the cutting machine 200 has the starting point of the cutting operation of the fabric ( P2) is set.

First, the control device 100 is provided. The control device 100 is for generating plan information of grinding and cutting operations using the grinding machine 200 and managing information of grinding and cutting operations actually performed through the grinding machine 200 . For example, the control device 100 may be a PC, etc., and a manager inputs grinding work plan information through a dedicated input program installed in the control device 100, and then sends the grinding work plan information to the grinding machine 200. By transmitting, the shearing operation is performed based on the shearing operation plan information in the shearing machine 200, and after the shearing is completed, the shearing operation plan information is generated so that the stretched fabric is cut and generated through the shearing machine 400 By sewing the finished pieces, clothes, etc. can be manufactured.

At this time, the podium and cutting operation plan information generated by the control device 100 can be transmitted to the pruning machine 200, that is, the controller 500 to be described later, through a wired or wireless communication network, and can be stored in a storage device such as a USB. can be transmitted by Here, the communication network includes not only closed networks such as LAN (Local Area Network) and WAN (Wide Area Network) and open networks such as the Internet, but also CDMA (Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), It may be a concept collectively referring to networks such as Global System for Mobile Communications (GSM), Long Term Evolution (LTE), Evolved Packet Core (EPC), and next-generation networks and computing networks to be implemented in the future.

In addition, the shearing work plan information includes a fabric style, a fabric roll number (Roll No.), a fabric distance (QTY), a spreading length, and a fabric fabric for a corresponding fabric fabric. It includes the number of spreaders (No. Spreading Length), the number of clothes per sheet of spread (No. Garment), and the preset operation division of spreading machine (Speading Setting).

The style of the fabric means a number given to the fabric style according to the difference in the pattern of the fabric, and the roll number means the management number of the fabric roll preset to manage the fabric roll, and the fabric fabric The distance of (QTY) means the total distance of the fabric wound on the roll, and the distance of the edge means the distance for one piece of fabric when the roll is unwound using a straightening machine.

In addition, the number of edges indicates how many layers of edges are formed when the woven fabric wound on the roll is stretched, which is determined by (distance of fabric) ÷ (distance of edges).

In addition, the number of clothes per platform means the number of clothes that can be made with one platform.

Depending on the material, there are various types of fabrics, such as soft fabrics, hard fabrics, fabrics with spandex, non-woven fabrics, thick fabrics, and thin fabrics. Therefore, it is necessary to set the operation pattern of the grinding machine, which corresponds to the speeding setting of the grinding machine. This may be different for each grinding machine.

Next, the pruning machine 200 is provided. The grinding machine 200 receives the grinding work plan information generated by the control device 100 through the controller 500 to be described later, executes grinding, and plans the grinding work for the actually executed grinding work. It functions to transmit information to the control device 100.

For example, since the control device 100 managed by a manager is usually located in an office and the grinding machine 200 driven by a worker is located at a work site, the control device 100 and the grinding machine 200 is located in a remote location, and the storage device serves to connect the control device 100 and the grinding machine 200.

Here, the shearing work plan information includes the number of actually worked plying (Woked Layer), fabric usage, fabric left over, and the number of clothes through plying (Total Garment) for the corresponding fabric roll. ), step work time of the stepping machine, step full work time including waiting time, etc. The number of layers actually worked (Worked Layer) means the number of layers in which the corresponding fabric roll is actually executed, and the fabric usage (Fabric Usage) means the amount (distance) used for the spreading of the corresponding fabric roll, Fabric Left Over means the remaining amount of fabric (distance) after stretching, and Total Garment means the number of garments to be generated after cutting according to the spreading machine. The step work time means the pure step work time for the corresponding textile roll, and the step full work time means the entire step work time for the corresponding textile roll, including waiting time. means time.

At this time, the grinding machine 200 may include its own grinding machine control interface (touch screen) like a conventional grinding machine, and the grinding operation plan information may be input by an operator to perform grinding.

In addition, the spreading machine 200 includes a fabric holder on which the fabric is placed, a fabric supply roller unit provided in a roller type to supply the fabric, and a cutting unit 210 to cut the fabric. It is movably installed on the working table 300 and performs grinding work, and detailed description of the same parts as the conventional grinding machine will be omitted.

Meanwhile, referring to FIG. 3 , the rail part 265 is provided along the longitudinal direction of the spreading machine 200 on the front surface of the spreading machine 200 . Here, the longitudinal direction of the stretching machine 200 means a direction perpendicular to the direction in which the fabric is stretched, that is, a direction in which the fabric is cut by the cutting unit 210 .

Also, the first control unit 261 is provided to be linearly transportable along the rail unit 265 . For example, at least a part of the first adjusting part 261 is provided in a form passing through the rail part 265 and is formed to have a 'c'-shaped cross section. In addition, it is linearly transferred along the rail part 265 in conjunction with a first lever 263 to be described later. At this time, in the combination of the first control unit 261, the rail unit 265, and the first lever 263 to be described later, the first control unit 261 operates according to the rotation of the first lever 263 to be described later. As long as it can be linearly transported along the outer circumferential surface of the rail unit 265, it can be formed in any shape, and for example, it can be coupled through a rack and pinion gear. Here, the first control unit 261 serves to align the end line (edge) of the fabric through the EPC sensor like a conventional pruning machine.

In addition, the second adjusting part 262 is provided to be linearly transportable along the longitudinal direction of the first adjusting part 261 . For example, the first adjusting part 261 is a guide rail formed along the longitudinal direction of the first adjusting part 261 parallel to the rail part 265 on one side of the outer circumferential surface of the first adjusting part 261. includes Here, at least a part of the second control unit 262 is provided in a form penetrating the guide rail, and is formed to have a rectangular cross section. In addition, it is linearly transferred along the guide rail in conjunction with a second lever 264 to be described later. Similarly, in the combination of the second control unit 262, the guide rail, and the second lever 264 to be described later, the second control unit 262 operates on the guide rail according to the rotation of the second lever 264 to be described later. It can be formed in any shape as long as it can be linearly transferred along the outer circumferential surface, and can be coupled through, for example, a rack and pinion gear.

In addition, the pruning machine 200 includes a reference frame 266 provided at an end of the second control unit 262 and a laser unit 267 provided at a lower portion of the reference frame 266 and emitting a laser downward. ) is further included.

In addition, the pruning machine 200 includes a first lever 263 that allows the first adjusting unit 261 to linearly feed when rotated, and a second lever 263 that allows the second adjusting unit 262 to linearly feed when rotated. A lever 264 is further included, and at one side of the rail part 265, a scale for measuring the distance from the edge of the worktable 300 to the edge of the fabric is formed, and the first control unit ( 261), a scale for measuring the distance from the edge of the fabric to the boundary point of the unused area of the fabric is formed. For example, the scale is a scale formed on a ruler for measuring a distance, and is formed along the longitudinal direction of the rail part 265 and the first adjusting part 261 .

That is, the laser unit 267 emits a laser in a direction toward the fabric that is extended on the top of the work table 300, and more accurate measurement is possible based on the laser emitted through the laser unit 267. There is an advantage to that. Thereafter, the operator sets the length of the fabric in the width direction by inputting the distance measured through the first adjusting unit 261 into the controller 100. In addition, when the operator inputs the distance measured by the second adjusting unit 262 to the control device 100, the control device 100 determines the distance measured through the first adjusting unit 261 and the control device 100. By adding the distances measured through the second control unit 262, the original point P2 for cutting of the fabric is set.

For example, referring to FIGS. 4 and 5, the first adjusting unit 261 and the second adjusting unit 262 are provided in a state aligned adjacent to one end of the spreading machine 200 in normal times. , As the first lever 263 and the second lever 264 are rotated by the operator, they are linearly transferred along the longitudinal direction of the grinding machine 200. At this time, when the first lever 263 rotates, the first control unit 261, the second control unit 262, the reference frame 266, and the laser unit 267 are linearly transported, and the second lever When 264 rotates, the second control unit 262, the reference frame 266, and the laser unit 267 are linearly transported.

Here, the operator rotates the first lever 263 in one direction to transfer the first control unit 261 to the other end, while the laser emitted from the laser unit 267 is directed to the top of the work table 300. Make sure that it matches the side end (edge) of the fabric that has been pruned. That is, the operator rotates the first lever 263 in one direction until the laser emitted from the laser unit 267 coincides with the edge of the fabric.

In addition, when the laser emitted from the laser unit 267 interferes with the edge of the fabric, the distance from the edge of the work table 300 to the first adjusting unit 261, that is, the first adjusting unit 261 The position of or the center position of the laser part 267 is confirmed through a scale formed on the rail part 265 and inputted to the control device 100. In other words, the transfer distance of the first adjusting unit 261, that is, the distance measured through the first adjusting unit 261 is input to the control device 100, and the control device 100 determines the corresponding point. It is to set the width direction length of the fabric as a standard. At this time, the first adjusting part 261 may be provided at both ends of the rail part 265, respectively. That is, when precise measurement is required, the control device 100 subtracts the distance measured through the first control unit 261 from the length of the rail unit 265 in the longitudinal direction of the fabric in the width direction. that can be set to At this time, the operator may input the distances measured through the first adjusting unit 261 and the second adjusting unit 262 to the control device 100 and the controller 500 to be described later, respectively.

Here, referring to (b) of FIG. 4, the fabric is usually aligned through a conventional EPC sensor, but the edge of the fabric actually stretched by the stretching machine 200 is wrinkled and does not form a straight line. and includes unused areas unsuitable for clothing manufacturing due to damage. In other words, if the edge of the fabric is used as the starting point for cutting, the wrinkled or damaged edge of the fabric is used in clothing production, resulting in defective products. For reference, in the conventional EPC sensor, for example, three pairs of proximity sensors are provided in a row to emit light when recognizing a fabric being transported between the three pairs of proximity sensors, and a worker grasps the movement path of the fabric through light. And, the first lever 263 is transferred so that the fabric is aligned, and since it is applied to a general grinding machine, a detailed description will be omitted.

Therefore, the operator rotates the second lever 264 in one direction according to the actual width of the stretched fabric and the state of the edge of the fabric so that the laser emitted from the laser unit 267 is spaced inward from the edge of the fabric. to be located at the point. That is, the laser unit 267 is located in the inner portion excluding the unused area near the edge of the fabric. In addition, the operator checks the distance from the edge of the fabric to the second adjusting unit 262, that is, the center position of the laser unit 267, through the scale formed on the first adjusting unit 261, and controls the input to the device 100. In other words, the transfer distance of the second adjusting unit 262, that is, the distance measured by the second adjusting unit 262 is input to the control device 100, and the control device 100 controls the first The point corresponding to the sum of the value measured and input through the control unit 261 and the value measured and input through the second control unit 262 is set as the cutting work origin P2 of the fabric.

Here, referring to FIG. 6, the control device 100 includes a monitor 101 on which a dedicated input program for the podium and cutting work is displayed, and virtual fabric and cutting are displayed on the screen of the monitor 101. The work origin (P2) is displayed. At this time, the cutting operation origin P2 is used as a reference point to generate numbering information and cam information (cutting information) forming a movement path of a tool, which will be described later.

That is, referring to FIG. 6 , the far end point P1 indicates an edge of the fabric, and the virtual fabric is displayed based on the far end point P1 formed on one side or both sides of the fabric. In addition, the cutting work origin (P2) is formed from the fabric end point (P1) to the inside of the fabric, and the cutting work range (R) is formed based on the cutting work origin (P2) formed on one side or both sides of the fabric. Determined, the operator generates numbering information and cam information for cutting within the cutting work range (R).

Here, a servomotor (not shown) for rotating the first lever 263 and the second lever 264 is provided, and a controller 500 to be described later may be formed to control the servomotor. Also, a proximity sensor (not shown) may be provided below the reference frame 266 to detect a far end. That is, when the controller 500, which will be described later, transmits a far-end detection signal from the proximity sensor while rotating the first lever 263 in one direction, the rotation of the first lever 263 is stopped, and the first lever ( 263), the far-end end point P1 is automatically generated as the position of the first adjusting unit 261 is calculated and transmitted to the control device 100 through the number of revolutions and the rotation angle. In addition, after the far-end end point P1 is generated, the controller 500, which will be described later, rotates the second lever 264 by a preset number of revolutions so that the second control unit 262 moves by a preset distance. The position of the second adjusting unit 262 is calculated and transmitted to the control device 100 so that the cutting work origin P2 is automatically generated. At this time, the operator can check whether the second control unit 262 is transported to an appropriate position through the laser unit 267, and generates numbering information or cam information using the control device 100 provided in the remote area. A manager can check whether the single work origin P2 is formed at an appropriate position through the monitor 101 .

As a result, the distances measured by the first adjusting unit 261 and the second adjusting unit 262 are input to the control device 100, so that the far end point P1 and the origin of the cutting operation ( P2) is easily generated, and the podium and cutting work plan information including the generated cutting origin P2 is transmitted to the controller 500 to be described later, and the origin of the actual fabric and the monitor 101 on the screen. Make the origin point coincide. In addition, by forming the cutting operation origin P2 inside the edge of the fabric according to the area of damage to the edge of the fabric, there is an advantage in preventing the damaged edge of the fabric from being used in clothing manufacturing.

On the other hand, the pruning machine 200 includes a head unit 220 provided on one side of the pruning machine 200 and performing printing according to the numbering information generated by the control device 100. That is, the head unit 220 is formed like a print head including a display means such as ink therein, and serves to print a mark 10 on the fabric according to the numbering information. At this time, the display 10 may be formed in any form as long as it can deliver information to the worker, such as figures, numbers, and letters.

In more detail, referring to FIG. 7 , the pruning machine 200 includes the fabric holder on which the fabric is placed, the fabric supply roller unit provided in a roller type to supply the fabric, and the cutting unit for cutting the fabric ( 210), a frame that supports the fabric holder and the fabric supply roller unit and guides the fabric to be transferred to the upper surface of the work table 300, and is movably installed on the work table 300. 250), a frame part 240 rotatably provided on one side of the spreading machine body 250 with respect to the spreading machine body 250, and a form penetrating at least a part of the frame part 240. A shaft portion 230 provided at an end of the frame portion 240 is included.

In addition, the frame part 240 includes a plurality of position display parts 241 arranged in parallel with the shaft part 230 between the frame part 240 and the shaft part 230 . At this time, the position display unit 241 serves to guide the installation position of the head unit 220, and if it can guide the installation position of the head unit 220, such as a circular groove, hole, scale, etc. It can be formed in any shape.

In addition, the head portion 220 includes a clamping portion 221 for fixing the head portion 220 to the shaft portion 230, and a direction from the clamping portion 221 toward the position display portion 241. It includes a protruding portion 222 formed to protrude into.

That is, the head portion 220 is installed on the shaft portion 230 by the clamping portion 221, and the operator matches the position display portion 241 and the protruding portion 222 to the head portion ( 220) can be easily installed at the required location. In addition, the position display unit 241 further includes an LED unit (not shown) that emits light under the control of a controller 500 to be described later. The LED unit serves to emit light so that the user can easily adjust the position of the head unit 220 . For example, the controller 500, which will be described below, emits light from the LED portion on the position display portion 241 corresponding to a point where the head portion 220 needs to be installed based on the cutting work origin P2 and numbering information. control as much as possible

And, the head part 220 further includes a sensor part 223 provided on one side of the head part 220 to sense the position and speed of the head part 220 . That is, the sensor unit 223 serves to sense the position information of the head unit 220 and the conveyed speed information and transmits them to the control device 100 . Therefore, there is an advantage in that it can be checked in real time whether the display 10 is accurately printed through the sensor unit 223 . At this time, the sensor unit 223 may be provided on one side of a plurality of wheels (not shown) provided at the lower part of the grinding machine body 250 so that the grinding machine body 250 can be transported. In addition, a drive motor (not shown) may be provided inside the grinder body 250 to provide a driving force so that the grinder body 250 can be transported, and the plurality of wheels are driven by the drive motor. Power is received so that the grinder body 250 can be transported.

And, the frame part 240 is rotatably installed on the pruning machine body 250 . For example, the frame part 240 may be hinged to a shaft (not shown) provided on one side of the grinder body 250, and the shaft is provided on one side of the grinder body 250 It can be rotated by the motor 251. That is, while the shaft is rotated by the motor 251, the frame part 240 can be rotated, and if the frame part 240 can be rotated, it can be formed in any shape.

Here, referring to FIG. 8 , when cutting the fabric while the cutting unit 210 is transported in the transverse direction of the fabric, the frame unit 240 rotates in a direction away from the fabric to be cut. Then, when the cutting of the cutting part 210 is completed, the frame part 240 is rotated to the original position so that the printing can be performed with the end of the head part 220 in contact with the upper part of the fabric. At this time, the cutting unit 210 may be reciprocally linearly moved by a transfer motor 252 provided on one side of the shearing machine body 250, and the cutting unit 210 is moved along the surface of the shearing machine body 250. It can be formed in any shape as long as it can be reciprocated and linearly moved in the width direction.

Referring to FIGS. 9 to 13, the spreading machine 200 formed in this configuration is first, while the spreading machine 200 is transported along the work table 300, the fabric is moved along the work table 300. to settle into For example, the pruning machine 200 located on the right side of the work table 300 is transported to the left along the work table 300 so that the fabric is seated on the work table 300. Then, as shown in FIGS. 10 and 11 , the cutting unit 210 cuts the fabric while being transported in the transverse direction of the fabric. For example, the fabric is cut while the cutting unit 210 located at the lower side relative to the fabric is transported upward. At this time, the frame unit 240 maintains a state of being rotated in a direction away from the fabric until the cutting unit 210 completes the cutting operation of the fabric, and returns to its original position when the cutting operation is completed. Thereafter, as shown in FIGS. 12 and 13, the head unit 220 prints the mark 10 on the fabric according to the numbering information while the spreading machine 200 is returned to its original position along the work table 300. For example, the surface of the fabric on which the head part 220 is cut while the pruning machine 200 located on the left side of the work table 300 is transferred to the right side along the work table 300 and returned to its original position. To print the mark (10) on.

As a result, the shearing machine 200 is transported in one direction while holding the front end of the fabric, and cuts the fabric in the transverse direction in a state in which the fabric is unfolded, and then releases the grip of the front end of the fabric returns to the original position, and allows the head part 220 to perform a numbering operation on the surface of the fabric.

Hereinafter, a method for setting the origin of a fabric according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 14, a generating step (S100) of generating grinding work plan information using a dedicated input program for grinding work, and after the generating step (S100), the grinding work plan information is transferred to the grinding machine (200).

That is, the control device 100 receives the measured values of the first control unit 261, the second control unit 262, and the sensor unit 223 and outputs them on the screen, so that the manager can control the far-end end point ( P1), the cutting origin (P2), and the current position of the head unit 220 can be easily grasped. For example, 6 to 10 heads 220 are displayed on the screen. At this time, the expected movement trajectory of the head unit 220 is displayed according to the installation position of the head unit 220 . That is, referring to FIG. 17, when the control device 100 receives the measurement value of the sensor unit 223 in a state in which a CAD file containing a cutting plan for the fabric is output in the dedicated input program, As shown in FIG. 18 , the expected movement trajectory of each head unit 220 is displayed. In other words, when the operator adjusts the position and spacing of the head part 220 and installs it, the sensor part 223 transmits the location information of the head part 220 to the control device 100, The controller 100 automatically adjusts an expected movement trajectory of the head unit 220 on the screen as the position of the head unit 220 is controlled.

In this state, the manager sets the point where the mark 10 on the fabric is to be printed. At this time, the position, color, shape, etc. of the display 10 can be set together. Thereafter, when the setting for the display 10 is completed as shown in FIG. 19 , the manager generates the numbering information through the control device 100 . That is, the numbering information includes information such as coordinates (position), color, and shape of the display 10 . Thereafter, the numbering information is transmitted to the pruning machine 200 so that the pruning machine 200 performs a grinding work according to the grinding work plan information.

Therefore, the setting step (S130) includes the point setting step (S131) of setting the point where the display 10 is required, and after the point setting step (S131), the information on the point where the display 10 is required, It includes a step of generating numbering information (S132) so that the display 10 is coordinated.

At this time, referring to FIG. 16, the system for setting the origin of the grinding machine of the present invention is provided on one side of the grinding machine 200, receives and stores the grinding and cutting work plan information, and the grinding machine 200 It further includes a controller 500 for controlling. That is, the controller 500 receives and stores the numbering information, and controls the head unit 220 according to the numbering information. In other words, the controller 500 controls the head unit 220 so that the head unit 220 can perform a printing operation based on the podium and cutting operation plan information transmitted via USB or the like. is to perform That is, the controller 500 inputs the numbering information to the information processing unit (CPU) of the head unit 220 so that the head unit 220 can print the display 10 . At this time, the controller 500 may transmit and receive information through wired or wireless communication.

In more detail, the controller 500 is provided on the left side of the pruning machine 200, receives the origin of the cutting operation of the fabric generated through the control device 100 such as a PC, and proceeds from the origin at a set interval. The LED unit located at the corresponding point emits light. That is, after the actual origin set by the operator matches the origin on the screen generated through the control device 100, the podium and cutting work plan information including the origin information generated through the control device 100 stored in the controller 500. Thereafter, the controller 500 controls the LED unit provided at a position corresponding to the numbering information based on the origin so that the operator can check the location where the head unit 220 is to be installed. Thereafter, the operator places the head unit 220 in a proper position, and then allows a numbering operation to be performed.

That is, in the transmitting step (S200), the piling work plan information and the cutting work plan information are transmitted to the pruning machine 200 through wireless or wired communication or to the pruning machine 200 through the storage device. It is a step. At this time, the sheeting operation plan information may be delivered to the shearer 400 as well as the shearing machine 200 .

Next, in the spreading step (S300), when the first adjusting unit 261 is transported in the direction of the fabric by the operator and the edge of the fabric coincides with the first adjusting unit 261, the work table ( 300) and the first measuring step (S310) in which the distance from the edge to the first adjusting unit 261 is measured, and after the first measuring step (S310), the fabric is held in a state where the tip of the fabric is held. By transporting in one direction, the unfolding step (S320) of unfolding the fabric, and the cutting step (S330) of cutting the fabric in the transverse direction after the unfolding step (S320), and the second control unit by the operator 262 is transferred to the inside of the fabric to set the origin, and a second measuring step (S340) in which the distance from the edge of the fabric to the second adjusting unit 262 is measured, and the second measuring step After (S340), a numbering step (S350) of performing a numbering operation on the surface of the fabric is included. Thereafter, a product is created through the cutting step (S400) of cutting the pruned fabric and the sewing step (S500) of cutting the cut fabric.

More specifically, in the first measuring step (S310), the far end point P1 is formed by a worker. That is, the operator operates the stretching machine body 250 so that one sheet of fabric is spread on the upper part of the work table 300, but while the one fabric is being stretched, the length of the fabric in the width direction is adjusted to the length of the fabric. 1. Position the adjusting part 261 at the edge of the fabric. Thereafter, the operator measures the distance from the edge of the work table 300 to the first adjusting unit 261 and inputs the distance to the control device 100 .

Next, in the unfolding step (S320), the length of the worktable 300 according to the pruning work plan information is determined by placing the one piece of fabric, which has been pruned in the first measuring step (S310), on the top of the worktable 300. It is extended by a predetermined length in the direction (longitudinal direction).

Next, in the transverse cutting step (S330), the finished fabric is cut in the transverse direction by the cutting unit 210.

Next, in the second measurement step (S340), the cutting work origin (P2) is formed. That is, the operator transfers the second control unit 262 in the inner direction of the fabric through the second lever 264 so that the second control unit 262 coincides with the boundary point of the unused area of the fabric Then, the distance from the edge of the fabric to the boundary point of the unused area of the fabric is measured and inputted to the control device 100 .

Here, the control device 100 adds the distance measured by the worker through the first adjusting unit 261 and the distance measured through the second adjusting unit 262 to determine the origin of the cutting operation of the fabric. let it be set

That is, referring to (b) of FIG. 6 , when the control device 100 receives the distance measured through the first adjusting unit 261, it is formed on the interface screen 110 of the monitor 101. The virtual fabric 50 is shown so that the edge of the virtual fabric 50 is located at a point vertically spaced apart by the input distance from one end of the virtual worktable 300 to be. At this time, the far end point P1 may also be shown.

Thereafter, when the control device 100 receives the measured distance through the second adjusting unit 262, the control device 100 inputs the input from the edge of the virtual fabric 50 formed on the interface screen 110 of the monitor 101. The cutting work origin (P2) is shown at a point vertically spaced apart by the specified distance. That is, the cutting work origin P2 is displayed at a point vertically spaced apart from one end of the virtual worktable 300 by two input distance values. At this time, the operator may also input the distance measured through the first adjusting unit 261 and the second adjusting unit 262 to the controller 500 so that the origin of the grinding machine 200 is set.

Next, the podium and cutting work plan information including the cutting work origin (P2) information generated through the control device 100 is input to the controller 500, and in the numbering step (S350), the 1 The numbering operation for the fabric of the chapter is performed. That is, the numbering operation is performed on the one sheet of fabric while the stretching machine body 250 is transported in the opposite direction to the direction in which the one sheet of fabric is spread.

At this time, the cutting work origin (P2) is used as the origin of numbering information for printing the numbering information. For example, referring to FIG. 18, the controller 100 aligns the origin of the numbering information generated by the manager to match the origin of the cutting work P2, so that the location of the real origin of the fabric and the virtual fabric are aligned. It is to match the position of the numbering origin of

And, among the plurality of position display units 241, light is emitted from the position display unit 241 corresponding to the origin of the cutting operation P2. Therefore, the operator can check whether the location display unit 241 where the light is emitted coincides with the boundary point of the unused area of the fabric. In addition, different lights are emitted from the position display units 241 corresponding to the position of the head part 220 according to the numbering information, so that the operator installs the head part 220 at the corresponding point.

Thereafter, in the iterative spreading step (S360), spreading and numbering operations are performed on the remaining fabrics according to the set origin.

Thereafter, when the pruning and numbering operations for all fabrics are completed, the fabrics are fixed using pins, etc., and then transferred to the cutting machine 400, so that cutting operations can be performed based on the cutting origin point P2. .

As a result, the manager who creates the podium and cutting work information can prevent the edge of the damaged fabric from being used in clothing manufacturing by generating numbering information and cam information (cutting information) based on the cutting work origin (P2). There is an advantage to being In addition, there is an advantage in that different origins can be easily set according to the length of the fabric in the width direction. In other words, to ensure that the actual utilization origin of the fabric, which is determined by the operator according to the length in the width direction of the fabric and the edge condition of the fabric, the origin of numbering work and the origin of cutting work (pattern cutting work) can be accurately aligned in virtual and real world. is to do At this time, information communication may be performed between the control device 100 and the controller 500 through wired/wireless communication, and values may be input by an operator and a manager.

It can include an item that allows you to open a file, an item that allows you to close the software, an item that allows you to open a recent file, and so on. At this time, as for the items that allow the file to be saved, if the original file is a making file, the file can be saved during and after editing and a new numbering file can be created in DXF. This file is a DXF file containing print headlines and numbering points.

In addition, the second selection area 112 may include a display setting item, the head unit 220 setting item, a display rotation setting item, and a unit setting item. Here, the manager can select print heads step by step, and the first line display corresponds to the first print head. And, all printheads can be selected, and some printheads can be canceled as needed.

In addition, the third selection area 113 is an item for setting the size, and the fourth selection area 114 is an item for providing a method of using a dedicated input program for the pruning work.

In addition, the direction setting area 115 is an item allowing the manager to set the display direction, and the basic setting area 116 is an item allowing setting items to be checked and corrected.

In addition, the trajectory display area 117 is an item for displaying the trajectory to be transferred by the head portion 220, and the numbering display area 118 is set by the manager through clicks or the like to set the display 10, It is an item that allows the user to see the set display 10. And, FIG. 19 is an example showing how the numbering information is generated.

As a result, the system for setting the origin of the grinding machine and the method for setting the zero point of the present invention have the advantage of facilitating the formation of a cutting information file by forming a cutting origin, which is a reference point, during cutting after grinding. In addition, since the end point of the fabric and the origin of the cutting operation are set at the same time before the trimming operation, there is an advantage in that numbering is performed during the trimming operation and then the cutting operation can be performed.
