  The present invention relates to a marking device, a cutting machine, and a marking method, and in particular, after performing perforation for perforation, the inner surface of the perforation hole is colored with a marking material, so that the sewing position, dart position, and pocket of the fabric can be obtained. The present invention relates to a marking device, a cutting machine, and a marking method for marking a position or the like.

In general, in the manufacturing process of clothing, bedding, vehicle interior, ship interior, train interior, furniture cover, etc., when cutting fabric, it is a mark for processing parts cut after cutting In order to do so, markings are made at predetermined positions (for example, sewing positions, dart positions, pocket positions, etc.).
As a method of applying marking, a method of performing perforation is known. The perforation is a method in which a sewing position or the like of a fabric is perforated and a mark such as a sewing position is formed by the formed hole.
However, with the perforation method, for example, when a large number of holes are formed in the fabric body, such as lace fabric, the perforated position becomes difficult to see after cutting.
For this reason, various methods for coloring a marking position with a marking material are known (see, for example, Patent Document 1 and Patent Document 2).

Japanese Examined Patent Publication No. 59-053362 (pages 4 to 6, FIGS. 4 to 8)

JP 05-195421 A (page 4, FIGS. 3 to 4)

As shown in FIG. 12, the marking device described in Patent Document 1 includes a liquid transport pipe 118 and a punch 126 connected to a fluid reservoir. When the piercing tool 126 is pierced into the superposed body of the object to be cut, the liquid stored in the liquid reservoir 116 flows down in the liquid transport 118 and flows into the piercing tool 126. The liquid that has flowed into the piercing tool 126 flows out from the opening formed at the lower end of the piercing tool 126, and marks the superposed body of the object to be cut.
The marking device for the material to be cut in the cutting machine described in Patent Document 2 colors the material to be cut simultaneously when the perforating needle 132 punches the material to be cut. As shown in FIG. 13, the ink 145 that has flowed out of the liquid tank 146 passes through the liquid passage and the liquid passage, and flows into the liquid supply passage formed in the perforating needle 132. When the perforating needle 132 pierces the material to be cut, the ink 145 that has flowed into the liquid supply passage flows out from the outflow hole formed in the lower end portion of the perforating needle 132 and marks the material to be cut.

However, according to the devices described in Patent Document 1 and Patent Document 2, since the ink is injected from above into the vertically installed punching tool and colored simultaneously with the drilling, it is difficult to control the coloring process. was there.
In other words, since the punching device also serves as a coloring device, the coloring process is easily affected by vibration during punching, and there is a problem that a large amount of ink comes out due to vibration and spreads on the fabric. In addition, since the ink is injected into the punch from above, the ink flow is also affected by gravity, so it is difficult to adjust the ink discharge amount. Some of them may have problems such as ink not adhering.
Furthermore, since the ink is injected into the punch from above, the viscosity of the ink is selected so that it can be stably supplied to the punch and discharged stably under the conditions of vibration and gravity. It was necessary to select and adjust the ink physical properties.
Furthermore, the ink ejection port needs to have a structure that is not easily affected by such vibration and gravity and does not clog, and the development and maintenance of the ink ejection port of the punching tool has been troublesome.

The present invention has been made in view of the above circumstances, and its object is to provide a marking device, a cutting machine, and a marking method that are less susceptible to the effects of gravity, vibration, and the like, and that can be stably marked on a material to be cut. There is to do.
Another object of the present invention is to provide a marking device, a cutting machine, and a marking method in which the configuration of the entire apparatus is simplified and the maintainability is improved.

According to the marking device according to claim 1, in the marking device in which a mark is applied in advance to a position to be processed after cutting the material to be cut before being cut, the marking device is cut. A support base on which a support surface on which the material to be cut is placed is formed is formed on the upper surface, a punching means for making a hole in the material to be cut placed on the support surface, and the punching means on the support base On the above, perforation means moving means for moving to the position, coloring means for coloring the inside of the hole, which is a long body that is formed at least thinner than the hole and whose side is threaded, and the long body The long body is provided with an absorbent body which is installed at a certain interval from and is impregnated with the coloring material and can exude, and pressing means for pressing the absorbent body against a side surface of the long body. On at least part of the surface of A coloring material supplying means for attaching the colorant, the colored means on said support base rotates, the coloring means moving means for moving the position of the elongated body, an axis length direction of the long continuous material A rotation driving means for controlling the marking device, and a control means for driving and controlling the marking device. The control means moves the punching means to the position by the punching means moving means. A hole is formed by the perforating means, the elongated body is rotated by the rotation driving means, and the absorber is pressed against the side surface of the elongated body by the pressing means. After supplying the coloring material, the coloring means moving means moves the elongated body of the coloring means to the position, and controls the inside of the hole at the position to be colored by the elongated body, Long body When supplying the coloring material, the absorber is pressed against the side surface of the elongated body by the pressing means, so that the absorber is formed in a spiral shape formed on the side surface of the elongated body. A protrusion is transferred to form a spiral groove, and the absorber rises in the length direction while closely contacting the elongated body along the spiral protrusion on the side surface of the elongated body and simultaneously absorbs the absorption The problem is solved by oozing the coloring material from the body and supplying the coloring material to the side surface of the elongated body .

Thus, since the perforating means and the coloring means are provided separately, the coloring process by the coloring means can be easily controlled.
In other words, in the conventional marking device in which ink is filled in the punch that is the punching means and colored simultaneously with the punching, the punching means that vibrates greatly and the coloring means are combined. Leakage of the material to be cut due to leakage, or conversely, ink was not sufficiently adhered to prevent the material to be cut from getting dirty.However, in the marking device of the present invention, the punching means and the coloring means are used. Since it is a separate body, the coloring process is less affected by vibration during drilling, and the coloring process can be easily controlled.

Further, the coloring means is formed of a long body that is formed at least narrower than the hole, and includes a coloring material supply means for adhering the coloring material to at least a part of the surface of the long body, the coloring material supply means Comprises an absorber that is installed at a certain distance from the elongated body and impregnated with the coloring material, and a pressing means that presses the absorber against a side surface of the elongated body, and the pressing means includes the The colorant is configured to be supplied to the side surface of the long body by pressing an absorber against the side surface of the long body.
Unlike the system in which a colorant discharge port is provided below the colorant storage tank and the colorant is directly applied to the material to be cut from the colorant storage tank, the colorant is uniformly stabilized throughout the coloring means. Can be supplied. As a result, it is possible to stably color the marking position of the material to be cut without spots.

Furthermore, the long body is provided with a rotation driving means for rotating the long body about the length direction of the long body, the side of the long body is threaded, and the rotation driving means rotates the long body. At the same time, the pressing means presses the absorber against the side surface of the elongated body, so that the absorber moves in the length direction while closely contacting the elongated body, and the side surface of the elongated body is moved to the side surface. When the colorant is supplied, the absorber engaged with the elongated body moves in the length direction of the elongated body simply by rotating the elongated body. There is no need to provide a separate driving device, and the configuration of the device can be simplified. When the configuration of the apparatus is simplified, the number of parts is reduced, which is preferable because maintenance becomes easy.
In addition, since the side surfaces of the long body are threaded, the colorant holding ability is higher than that of a flat surface, which is preferable.

In addition, the marking device further includes a punch lifting / lowering driving unit that moves the punch up and down, and a drill lifting / lowering driving unit that moves the marking drill up and down, and the drilling unit includes a substantially cylindrical punch, The elongate body constituting the coloring means is formed of a marking drill formed to be narrower than the punch and having a side face threaded, and the rotation driving means is configured to simultaneously rotate the punch and the marking drill. In the state where the rotation driving means rotates the punch and the marking drill, the control means lowers the leading end of the punch to at least the lower end of the material to be cut, and the cutting material is lowered. And at least a part of the surface of the marking drill by the coloring means. After depositing the timber, the drill elevating drive means is configured to control so as to adhere the colorant to the marking drill inside the hole of the object to be cut material down to within said bore Since the material to be cut can be perforated with the punch rotated, it is preferable that the material to be cut can be reliably perforated. In addition, since marking can be performed while the marking drill is rotated, uneven coloring of the coloring material can be prevented, and uniform marking can be performed, which is preferable.

In addition, it is preferable that the marking device is provided in a cutting machine that cuts a material to be cut into a desired shape with a cutter because marking and cutting can be performed at a time.
In addition, the material to be cut is placed on the support surface of the support base, and the post-cutting material is cut by the punching means moving means on the support base. a punch moving step of moving the punch in position, with a hole in the position of the object to be cut material down until the lower end of the object to be cut material the tip of the punch, threaded spiral on the sides by the rotary drive means the formed marked drill is rotated by Rukoto pressing the absorber colorant is impregnated on the sides of the marking drill pressing means, the absorbent body to the marking drill side threaded spiral formed of The protrusion is transferred to form a spiral groove, and along the spiral protrusion on the side surface of the marking drill, the protrusion is closely contacted with the marking drill in the longitudinal direction. When the absorber is increased and at the same time step piercing and adhesion said colorant bleeds out from the absorber to attach the colored material on the sides of the marking drill, the marking drill, on said support base, moved to the position And a coloring step of coloring the inside of the hole of the material to be cut by lowering the marking drill at the position and smoothly marking the material to be cut It is possible to carry out the marking process and the cutting process on a large number of objects to be cut in a short time, which is preferable.

According to the present invention, since the coloring means and the coloring material supply means are configured separately, the coloring material can be attached to the outside of the coloring means. Therefore, since the viscosity range of the coloring material which can be used becomes wide, the room for selection of a coloring material spreads according to the kind of cutting material, cost, etc.
In addition, since a coloring material is attached to the outside of the coloring means and marking is performed with the attached coloring material, extra coloring material does not adhere to the material to be cut. Therefore, it is possible to prevent marking bleeding, colorant leakage, etc. due to excessive outflow of the coloring material, which is a problem of the conventional marking device that causes the marking material to flow out from the inside of the coloring means through the coloring material outflow hole. It becomes possible.

Further, since the coloring material can be attached to the outside of the coloring means, and the excess coloring material does not adhere to the material to be cut, the coloring material attached to the material to be cut is dried in a short time.
Therefore, it is possible to prevent the color from being transferred to another place at the time of pickup after the end of cutting.

Furthermore, since the coloring material can be attached to the outside of the coloring means, the coloring material is solidified and colored inside the coloring means, which is a problem of the conventional marking device that causes the marking material to flow down inside the coloring means. It is possible to prevent the coloring material outflow hole from being clogged with the material.
Therefore, it is possible to avoid problems such as marking unevenness caused by solidification of the coloring material inside the coloring means and clogging at the coloring material outflow hole.

Further, in the conventional marking device that causes the coloring material inside the coloring means to flow down, a coloring material tank for storing the coloring material, a coloring material flow path, a control device such as an adjustment valve for controlling the coloring material outflow, and a driving device. Therefore, the number of parts is large and the control becomes complicated.
However, in the marking device of the present invention, since the coloring material is attached to the outside of the coloring means, the number of parts can be reduced as compared with the conventional marking device, and a complicated control system is not required. .
Therefore, the manufacturing cost of the marking device can be reduced, and maintenance is easy.

The drill cylinder 21 is fixed on the fixed plate 25 so that the piston rod 21a protrudes to the lower part of the fixed plate 25. The lower end of the piston rod 21 a is screwed to the drill lifting plate 26.
The drill elevating plate 26 is formed as a rectangular plate, and has a hole 26a for fixing the drill holder 30f. The drill lifting plate 26 moves up and down with the vertical movement of the piston rod 21a, and plays a role of transmitting the vertical movement to the marking drill 30a.
As shown in FIGS. 2 and 3, the punch cylinder 22 and the drill cylinder 21 are arranged on the fixed plate 25 in a state where the straight line connecting the centers of the cross sections is substantially perpendicular to the guide rail 5. It is arranged on the guide rail 5 side of the fixed plate 25.

The drill pulley 30b is for rotating the marking drill 30a, and a known timing pulley is used. The drill pulley 30b is installed on the upper surface of the fixed plate 25, and the timing belt 11 is wound around the side surface.
A ball spline holder 30i made of a hollow cylindrical body is fixed to the shaft hole of the drill pulley 30b, and a ball spline 30h is fixed inside the ball spline holder 30i.
The ball spline shaft 30e is fixed to the drill pulley 30b via a ball spline 30h and a ball spline holder 30i at a position slightly below the center in the length direction. A drill holder 30f is provided around the ball spline shaft 30e at a position below the drill pulley 30b.

The lower end of the ball spline shaft 30e is located slightly below the upper end of the drill holder 30f, and a support portion 30d is continuous below the ball spline shaft 30e. The lower end of the ball spline shaft 30e and the upper end of the support portion 30d are circumferentially fixed to the drill holder 30f.
The drill holder 30f is penetrated by the hole 26a of the drill raising / lowering plate 26 via the bearing.
At the upper end of the drill holder 30f, a ring-shaped fixing member 30g is provided at a position above the drill lifting plate 26, and a marking drill 30a is provided with a bearing interposed therebetween.

Thus, the marking drill 30a is fixed through the hollow portions of the ball spline 30h and the drill holder 30f. The ball spline 30h is fixed to the drill pulley 30b, and the drill holder 30f is disposed on the drill lifting plate 26.
Thus, the marking drill 30a is configured to be able to transmit the rotational force from the drill pulley 30b and the vertical movement from the punch lifting plate 27, and the inner surface of the hole drilled by the punch device 29 can be colored with ink. It becomes possible.

The pressing member 31 is a member for fixing the fabric 10 so that it does not move when marking.
The presser member 31 includes a ball spline bearing 31c, a shaft 31b, a presser foot 31a, and a spring 31d as main components.
The ball spline bearing 31 c is a known ball spline bearing, and is fixed through the drill lifting plate 26.

The shaft 31b is a known ball spline shaft, and the ball spline bearing 31c is positioned on the outer periphery of the upper end in a normal state.
When a force is applied to push down the ball spline bearing 31c along the shaft 31b, the ball spline bearing 31c is configured to be slidable downward along the shaft 31b by a ball provided on the inner wall.
A presser foot 31a is fixed to the lower end of the shaft 31b.
The presser foot 31a is for fixing the fabric 10, and is formed of a rectangular plate, and a through hole 31e is formed at a position through which the drill portion 30c passes.
A spring 31d is wound around the shaft 31b.
The spring 31d is formed of a known coil spring, and urges the ball spline bearing 31c upward to keep the distance between the presser foot 31a and the ball spline bearing 31c constant, and the drill lifting plate 26 is lowered. When pressing, it plays a role of pressing the presser foot 31a against the fabric 10.

Next, operation mechanisms of the punch device 29, the ink supply device 28, and the drill device 30 will be described.
The rotation mechanism of the punch 29c and the marking drill 30a is as follows.
As shown in FIG. 3, a motor pulley 23b, a punch pulley 29b, and a drill pulley 30b are disposed on the upper surface of the fixed plate 25, and a timing belt 11 is engaged with the motor pulley 23b, the punch pulley 29b, and the drill pulley 30b.
The punch pulley 29b and the drill pulley 30b are configured such that when the motor pulley 23b performs a rotational motion by the operation of the motor 23, the rotational motion is transmitted by the timing belt 11 and can be rotated.
The punch 29a can rotate in conjunction with the rotation of the punch pulley 29b, and the marking drill 30a can rotate in conjunction with the rotation of the drill pulley 30b. Thus, the punch 29a and the marking drill 30a can be rotated by the rotation of the motor 23.

Based on FIG. 4, the operation | movement of the raising / lowering motion of the punch apparatus 29 is demonstrated. The raising / lowering motion of the punch device 29 is performed in a state where the punch 29c is rotated.
Compressed air is introduced into an upper port (not shown) of the punch cylinder 22 and the piston of the punch cylinder 22 moves forward. As a result, the piston rod 22a extends downward, and a force in the U direction is applied to the punch lifting plate 27. The plate 27 is lowered. By this force, the punch blade 29c is lowered to the position of the punch 29U.
At this time, the punch blade 29c, the ball spline shaft 29d, the bush collar 29l, the slide bush 29k, and the fixing member 29g are lowered together with the punch holder 29f, but the center shaft 29e is fixed to the punch support plate 41d. Does not descend.
In this way, the tip of the punch blade 29c, which was substantially at the same height as the tip of the center shaft 29e when not in operation, descends below the center shaft 29e.

When the punch blade 29c is lowered to the lower end of the fabric 10, a hole is made in the fabric 10, and the punch blade 29c is in a state in which a circular perforated object formed by drilling is fitted.
When compressed air is introduced into a lower port (not shown) of the punch cylinder 22 in a state where the punch device 29 is lowered, the piston moves backward so that the piston rod 22a of the punch cylinder 22 is pulled upward. With this movement, the punch raising / lowering plate 27 rises and the punch blade 29c rises.
At this time, since the tip of the punch blade 29c returns to substantially the same height as the tip of the center shaft 29e, the drilled object fitted in the hollow portion of the punch blade 29c is pushed downward by the lower end of the center shaft 29e.

Based on FIGS. 5 and 6, the operation of the ink supply device 28 in the up and down / slide motion will be described. The ink supply device 28 moves up and down and slides while the marking drill 30a is rotated.
When compressed air is introduced into the marker cylinder 32 and the piston rod 32a extends, the slide base 28d connected to the piston rod 32a via the frame 32d moves in the W direction along the horizontal rail 28b together with the horizontal guide 28c. .
Since the ink reservoir 28a is connected to the slide base 28d, when the slide base 28d moves in the W direction, the ink reservoir 28a also moves in the W direction and reaches the position 28W. At this time, the felt 28n of the ink reservoir 28a is pressed against the drill portion 30c.

Then, the ink filled in the ink reservoir 28a oozes out of the felt 28n due to the pressure.
Further, when the ink reservoir 28a is pressed against the drill portion 30c, the spiral mold of the drill portion 30c is attached to the felt 28n, and the spiral groove is transferred to the felt 28n.

Since the drill portion 30c is rotating, when the screw-like groove is formed in the felt 28n, the felt 28n can function as a female screw, and the ink reservoir 28a is formed along the drill portion 30c. Start climbing.
In this manner, the felt 28n moves upward along the drill portion 30c while being pressed against the drill portion 30c, whereby ink is attached to the portion of the surface of the drill portion 30c through which the felt 28n has passed.

When the ink reservoir 28a rises and reaches the position of 28V, the sensor detection member 28j that has risen together is detected by the sensor 28i.
When the sensor detection member 28j is detected by the sensor 28i, the port for introducing compressed air to the marker cylinder 32 is changed, and the piston rod 32a is returned to the original state. The force in the W direction on the slide base 28d disappears and the slide base 28d returns to the original position, so that the ink reservoir 28a returns to the original position.

Based on FIG. 5, the operation of the drill device 30 and the presser member 31 will be described. The lifting / lowering motion of the drill device 30 is performed with the marking drill 30a rotated.
When compressed air is introduced into an upper port (not shown) of the drill cylinder 21 and the piston of the drill cylinder 21 moves forward, the piston rod 21a extends downward, and a force in the T direction is applied to the drill lifting plate 26, and the drill moves up and down. The plate 26 is lowered.
With this force, the marking drill 30a is lowered together with the drill holder 30f to the position of the marking drill 30T together with the fixing member 30g.

At this time, the holding member 31 fixed to the drill lifting plate 26 is also lowered as the drill lifting plate 26 is lowered. The presser foot 31a is lowered to the position of the presser foot 31T.
When the presser foot 31a comes into contact with the fabric 10 at the position of the presser foot 31T, the presser foot 31a and the shaft 31b cannot be lowered any more, and the force that the shaft 31b tends to rise upward with respect to the ball spline bearing 31c. work. Since the shaft 31b and the ball spline shaft 31b are slidable by a ball, the shaft 31b moves upward with respect to the ball spline bearing 31c, and the tip of the shaft 31b is moved from the tip of the ball spline bearing 31c. Protruding.
As a result, the ball spline bearing 31c descends as the drill lift plate 26 descends while the presser foot 31a is positioned on the presser foot 31T on the fabric 10, so that the distance between the presser foot 31a and the ball spline bearing 31c is as shown in FIG. The spring 31d contracts to the range of S. When in this state, the spring 31 d plays a role of pressing the fabric 10.
At this time, the lowered marking drill 30T is in a state of penetrating a hole formed in the presser foot 31a.

When compressed air is introduced into a lower port (not shown) of the drill cylinder 21 in a state where the drill device 30 and the pressing member 31 are lowered, the piston moves backward so that the piston rod 21a of the drill cylinder 21 is pulled upward.
Along with this movement, the drill lifting plate 26 rises, and the drill portion 30c rises together with the drill holder 30f.

  At this time, the presser member 31 also moves up as the drill lift plate 26 moves up. When the drill raising / lowering plate 26 is raised, the spring 31d that has contracted has a force to return to the natural length, so that the presser foot 31a and the ball spline 31c return to the state of the solid line in FIG.

(Operation of marking unit 7)
Next, the operation of the marking unit 7 having the above configuration will be described.
FIG. 7 is a main process diagram illustrating a process flow of the marking unit 7 according to the embodiment of the present invention, and FIGS. 8 to 11 are flowcharts illustrating control of the marking unit 7.
The processing in FIGS. 7 to 11 is controlled by a CPU (not shown) built in the control device 9.

The process of the marking unit 7 in FIG. 7 starts when a start command button (not shown) set in the operation device 8 is operated. In the marking preparation processing step of step 1, the marking unit 7 is moved to a position where the fabric 10 is punched.
Thereafter, the punching process in step 2 and the ink adhering process in step 3 are performed in parallel. In the punching process of step 2, the marking position of the fabric 10 is punched. In addition, in the ink adhering process of step 3, ink is adhering to the drill portion 30c.
Then, the coloring process of the process 4 is implemented. In Step 4, a marking material is attached to the inner wall of the hole drilled in the fabric 10 in Step 2. When the coloring process of the process 4 is completed, when the next marking position is set, the process returns to the process 1 and the above processes 1 to 4 are repeated. If the next marking position is not set, the process ends.

Based on FIG. 8 thru | or FIG. 11, the process of each process of FIG. 7 is demonstrated. The processing of the flowcharts of FIGS. 8 to 11 is controlled by the CPU of the control device 9.
FIG. 8 shows processing of the marking preparation processing step of step 1 in FIG.
When a start command button (not shown) set in the operation device 8 is operated, the process of FIG. 8 starts.
First, the first record of the marking position data table designated in advance by the operating device 8 is read (step S101).

This marking position data table is a table in which data indicating where marking is performed on the fabric 10 placed on the fabric support base 2 is stored.
The data in the marking position data table is input in advance by the user by a method such as converting the cutting design drawing into a data format suitable for the marking device of the present embodiment.
In the marking position data table, the position data of one mark is one record. Items in the marking position data table include an X coordinate (position in the longitudinal direction of the fabric support base 2 in FIG. 1) and a Y coordinate (position in a direction perpendicular to the longitudinal direction).
Further, one table includes a record of mark positions to be marked by one marking process.
Next, the marking unit 7 is moved to the marking position specified by the X coordinate and Y coordinate of the read record (step S102).

Next, it is determined whether or not the marking unit 7 has reached the marking position (step S103).
When it is determined that the marking unit 7 has not reached the marking position (step S103: NO), it is determined whether or not a predetermined time, for example, 4 seconds has elapsed (step S104). If it is determined that the predetermined time has elapsed (step S104: Yes), a buzzer is sounded to issue an error warning and the motor 23 is turned off (step S105), and the process is terminated.
Stopping the motor 23 stops the rotation of the drill part 30c and the punch blade 29c.

  In step S104, it is determined whether or not the predetermined time has elapsed. For example, if 4 seconds have elapsed since the start of movement, but the marking unit 7 does not reach the marking position, the marking unit 7 is Since there is a high possibility that an abnormality has occurred, an error warning is issued and the process is terminated.

When it is determined that the marking unit 7 has reached the marking position (step S103: Yes), the movement of the marking unit 7 is stopped (step S106). Whether the marking unit 7 has reached the marking position is determined by comparing the coordinates of the current position of the marking unit 7 with the coordinate data of the read record. Thereafter, the motor 23 is driven (step S107).
When the motor 23 is driven, the motor pulley 23b connected to the output shaft 23a of the motor 23 rotates, and the punch pulley 29b and the drill pulley 30b are also driven via the timing belt 11 and rotate in the same direction as the motor pulley 23b. As a result, the punch 29a and the marking drill 30a rotate. Thereafter, the process ends.

FIG. 9 shows the punching process in step 2 of FIG.
The flowchart of FIG. 9 starts when it is detected that the motor is driven in step S107 of FIG.
First, compressed air is introduced into an upper port (not shown) of the punch cylinder 22 to advance the piston of the punch cylinder 22 (step S201). As a result, the piston rod 22a is lowered and the punch blade 29c connected to the punch lifting plate 27 is lowered. The punch blade 29c is lowered by the pressure of the cylinder 22 while rotating, so that the fabric 10 can be punched.

Next, it is determined by a proximity sensor (not shown) whether or not the punch blade 29c has reached the lower limit position (step S202).
The determination as to whether or not the lower limit position has been reached may be made by a touch sensor or an encoder that measures the moving distance, or by detecting that a predetermined descent time has passed with a timer or the like. good.
When it is determined that the punch position has not reached the lower limit position (step S202: No), it is determined whether a predetermined time, for example, 4 seconds has elapsed (step S203).
When it is determined that the predetermined time has not elapsed (step S203: No), the process returns to S202, and it is determined whether or not the punch blade 29c has reached the lower limit position (step S202). When it is determined that the predetermined time has elapsed (step S203: Yes), a buzzer is sounded to issue an error warning, and the motor 23 is turned off (step S204), and the process is terminated.
Stopping the motor 23 stops the rotation of the drill part 30c and the punch blade 29c.

  In step S204, it is determined whether or not the predetermined time has elapsed. For example, when 4 seconds have elapsed since the descent started but the punch blade 29c has not reached the lower limit, some abnormality has occurred. The processing is terminated because there is a high possibility of being present.

If it is determined that the punch blade 29c has reached the lower limit (step S202: Yes), compressed air is introduced into a lower port (not shown) of the punch cylinder 22 and the piston of the punch cylinder 22 is retracted (step S205). As a result, the piston rod 22a rises and the punch blade 29c connected to the punch lifting plate 27 rises.
Thereafter, the process ends.

FIG. 10 shows the process of the ink adhesion process in step 3 of FIG.
The flowchart of FIG. 10 starts when it is detected that the motor 23 is driven in step S107 of FIG.

First, compressed air is introduced into an outer port (not shown) of the marker cylinder 32 to advance the piston of the marker cylinder 32. (Step S301). As a result, the piston rod 32a extends in the direction of the drill portion 30c, and the ink reservoir 28a moves in the direction of the drill device 30. The felt 28n is pressed against the drill portion 30c.
When the drill portion 30c is pressed, the felt 28n has a screw shape and a female screw is formed.
Since the drill portion 30c is rotating, the ink reservoir 28a rises along the drill portion 30c by the action of the felt 28n whose surface is a female screw.
Next, it is determined whether or not the ink reservoir 28a has reached the upper limit (step S302). Whether the ink reservoir 28a has reached the upper limit is detected by the sensor 28i.
When it is determined that the ink reservoir 28a has not reached the upper limit (step S302: No), it is determined whether a predetermined time, for example, 4 seconds has elapsed (step S303).

If it is determined that the predetermined time has not elapsed (step S303: No), the process returns to step S302 to determine whether or not the ink reservoir 28a has reached the upper limit (step S302). If it is determined that the predetermined time has elapsed (step S303: Yes), a buzzer is sounded to issue an error warning and the motor 23 is turned off (step S304), and the process is terminated.
Stopping the motor 23 stops the rotation of the drill part 30c and the punch blade 29c.
In step S303, it is determined whether or not the predetermined time has elapsed. The ink reservoir 28a reaches the upper limit even though, for example, 4 seconds have elapsed since the ink reservoir 28a started moving toward the drill device 30. If not, it is highly likely that some abnormality has occurred, so an error warning is issued and the process is terminated.

  When it is determined that the ink reservoir 28a has reached the upper limit (step S302: Yes), compressed air is introduced into the inner port opposite to when the piston is advanced, and the piston of the marker cylinder 32 is retracted (step S305). ). Thereby, the piston rod 32a returns to the origin direction away from the drill part 30c. Since the ink reservoir 28a does not receive the urging force from the marker cylinder 32, the pressure contact with the drill portion 30c is released, and the ink reservoir 28a falls to the lower end that is the origin. Thereafter, the process ends.

FIG. 11 shows the process of the coloring process step of step 4 in FIG.
The flowchart of FIG. 11 starts by detecting that the piston of the punch cylinder 22 has been retracted in step S205 of FIG. 9, and detecting that the piston of the marker cylinder 21 has been retracted in step S305 of FIG.

First, the marking unit 7 is moved to the marking position (step S401).
That is, since the punch 29a and the marking drill 30a are installed at different positions on the marking portion 7, it is necessary to move the marking portion 7 in order to color the marking punch 30a with the marking drill 30a. It is.
Next, it is determined whether or not the marking drill 30a has reached the marking position (step S402). When it is determined that the marking drill 30a has not reached the marking position (step S402: No), it is determined whether or not a predetermined time, for example, 4 seconds has elapsed (step S403).

When it is determined that the predetermined time has not elapsed (step S403: No), the process returns to step S402, and it is determined whether or not the marking drill 30a has reached the marking position (step S402). When it is determined that the predetermined time has elapsed (step S403: Yes), a buzzer is sounded to issue an error warning and the motor 23 is turned off (step S404), and the process is terminated.
Stopping the motor 23 stops the rotation of the drill part 30c and the punch blade 29c.
In step S403, it is determined whether or not the predetermined time has elapsed, for example, if the marking unit 7 has not reached the marking position even though 4 seconds have elapsed since the start of movement, the marking unit 7 Since there is a high possibility that some abnormality has occurred, an error warning is issued and the processing is terminated.

When it is determined that the marking drill 30a has reached the marking position (step S402: Yes), the movement of the marking unit 7 is stopped (step S405). In step S405, the marking unit 7 stops in a state where the drill unit 30c is positioned above the hole drilled in the punching process of step 2. The marking unit 7 has reached the marking position by collating the coordinates of the current position of the marking drill 30c with the coordinate data of the read record.
Next, compressed air is introduced into an upper port (not shown) of the drill cylinder 21, and the piston of the drill cylinder 21 is advanced (step S406). Thereby, the piston rod 21a descends and the drill portion 30c connected to the drill lifting plate 26 descends. The lowered drill portion 30c comes into contact with the inner surface of the hole drilled in the punching process, and the inner surface of the hole is colored.

Thereafter, it is determined by a proximity sensor (not shown) whether or not the drill unit 30c has reached the lower limit position (step S407).
The determination as to whether or not the lower limit position has been reached may be made by a touch sensor or an encoder that measures the moving distance, or by detecting that a predetermined descent time has passed with a timer or the like. good.
When it is determined that the drill unit 30c has not reached the lower limit position (step S407: No), it is determined whether a predetermined time, for example, 4 seconds has elapsed (step S408).

When it determines with predetermined time not having passed (step S408: No), it returns to S407 and it is determined whether the drill part 30c reached | attained the lower limit position (step S407). If it is determined that the predetermined time has elapsed (step S408: Yes), a buzzer is sounded to issue an error warning and the motor 23 is turned off (step S409), and the process is terminated.
Stopping the motor 23 stops the rotation of the drill part 30c and the punch blade 29c.
In step S408, it is determined whether or not the predetermined time has elapsed. For example, if 4 seconds have elapsed since the descent started but the drill unit 30c has not reached the lower limit, some abnormality has occurred. This is because the process is terminated.

When it is determined that the drill portion 30c has reached the lower limit position (step S407: Yes), compressed air is introduced into a lower port (not shown) of the drill cylinder 21 and the piston of the drill cylinder 21 is retracted (step S410).
That is, by retracting the piston of the drill linder 21, the piston rod 21a of the drill cylinder 21 is raised, and the drill portion 30c connected to the drill lifting plate 26 is raised.

Next, it is determined whether or not there is an unprocessed record that has not yet been read in the designated marking position data table (step S411).
If it is determined that there is an unprocessed record (step S411: Yes), the next record is read, and the process proceeds from A to A in FIG. 8 to step S102, where the X and Y coordinates of the read record are specified. The marking unit 7 is moved to the marking position (step S102).
If it is determined that there is no unprocessed record (step S411: No), the motor 23 is turned off (step S413). Stopping the motor 23 stops the rotation of the drill part 30c and the punch blade 29c. Thereafter, the process ends.
As described above, when there is an unprocessed record, Steps 1 to 4 are repeated until all marking positions are marked, and the process is terminated when all marking positions are marked.
When marking is completed, the cutting process of the fabric 10 is started. The cutting process is performed by a known method. By performing the marking process before the cutting process, it is possible to perform the marking process in a state where the cloth 10 is firmly fixed on the cloth support table 2 by using a vacuum pump (not shown).
