15, the pressing lever 302 presses the tape T from above by the leaf spring in a state in which the scalpel 301 is operated. Thus, the tape T is prevented from being displaced when the tape supply device 3 moves back and forth. When the tape T is set on the tape supply device 3, the tape T before the replacement is lifted by lifting the press lever 302 by hand, and the tape T to be used is inserted to remove the tape end Against the side surface of the scalpel 301, and the lever 302 is returned and fixed.

That is, the press lever 302 is supported by the transfer arm 307 and moves up and down together with the scalpel 301 to press the tape T on the tape supply path.

44, a tape feeding path formed on the upper surface of the movable block 33 is provided with a slit-shaped tape retracting hole (not shown) adjacent to the downstream side of the tape feeding direction with respect to the abutting position of the scalpel 301, (33a) is formed. A guide plate 308 for guiding the tape T to the tape retracting hole 33a is formed on the plane on the downstream side of the tape 301 in the tape feeding direction.

The tape retracting hole 33a is provided in the first extension control (see Fig. 44) to be described later (see Fig. 44) for advancing the tape Tm after the tape Tm is cut It is retirement space.

44, the guide plate 308 is suspended from the scalpel 301 in an obliquely downward direction, and the distal end of the guide plate 308 is positioned at the entrance of the tape retracting hole 33a in a state in which the scalpel 301 is lowered So that when the rear end of the tape Tm moving backward comes into contact with the tape Tm, the tape Tm is guided to the tape retracting hole 33a side.

16 and 17, the tape feeding mechanism 38 is provided with a roller switching mechanism 330 for swinging the holder 383 to switch the front roller 381 and the rear roller 382 .

The roller changing mechanism 330 is constituted by a connecting lever 332 and a cylinder unit (roller switching cylinder) 335 and the like.

And a latching pin 398 is engaged with a downward extension portion 397 formed on the rear bracket 396 attached to the side surface of the holder 383. The engaging pin 398 is inserted into the elongated hole 333 formed at the front end of the connecting lever 332. [ The connecting lever 332 is rotatably supported by a second supporting shaft 331 whose middle portion is fixed to the side surface of the movable block 33. [

At the rear end of the connecting lever 332, a cylinder unit 335 having an upwardly directed piston rod 336 is disposed. The cylinder unit 335 is fixed to the side surface of the movable block 33. The rear side of the connecting lever 332 is connected to the upper end of the piston rod 336 through a connecting piece 334.

That is, the roller switching mechanism 330 swings the holder 383 as a fulcrum between the two rollers, so that only one of the two rollers is selectively pressed against the tape.

The roller switching mechanism 330 includes a connecting lever 332 having one end connected to the holder 383, a second supporting shaft 331 for rotatably supporting the connecting lever 332, And a cylinder unit 335 connected to the rear end of the lever 332.

18, when the cylinder unit 335 is operated to lower the piston rod 336 from the state in which the rear roller 382 is lowered on the tape supply path to transfer the tape (Fig. 17) Clockwise about the second support shaft 331 at the intermediate portion. The rear bracket 396 moves upward through the elongated hole 333 and the engaging pin 398 so that the holder 383 integrated with the bracket 396 moves from the center support shaft 385 to the point It oscillates counterclockwise. As a result, the rear roller 382 is lifted from the tape supply path, and the front roller 381 is lowered onto the tape supply path to transfer the tape.

The sewing operation of the tape Tm with respect to the body (LI (or RO)) by the tape stitching and attaching apparatus is started (started) as shown in Figs. 21, 22 and 23.

21, a needle 22 is placed on the body LI (or RO) at the start of sewing in the sewing start state immediately before the tape Tm is fed to the body LI (or RO) The upper and lower threads are knotted by forming a needle sweat in the body LI (or RO) by a needle thread NT and a lower thread supplied from a bobbin to the needle 22 at least three times or more.

Thereafter, when the supply of the tape Tm is started on the body LI (or RO), as shown in Fig. 22, the front roller 381 is rotated to bring the tape Tm down to the needle 22 And is against the upper thread NT which is connected to the needle 22 and the body LI (or RO). Tm1 is a tape stitched in the last time.

23, the body LI (or RO) is moved along the tape feeding direction by the XY transfer device and the front roller 381 is rotated to transfer the tape to the body LI Or RO) on the tape Tm by passing the needle 22 more than once through the upper and lower yarns to seal the tape Tm and the body LI (or RO).

At this time, the XY feeding device is operated so that the body is fed to a small sewing pitch of 1 mm (for example, 0.7 mm to 1.3 mm) smaller than a normal sewing pitch (for example, 2 mm to 2.5 mm) The motor M1 is operated so that the amount of feed is equal to the amount of the small-sized sewing pitch or the amount of feeding twice the small-sized sewing pitch. Since the actual tape feed amount changes depending on the characteristics (hardness, stretchability, slipperiness) of the tape to be used, the setting transfer amount by the motor M1 can be changed by setting on the display device 6 .

That is, when the tape is stitched on the body of the shoe, the stitches of at least three needles are formed on the body at the start of sewing, and then the sewing start position of the tape is supplied to the lower side of the needle, After a needle stitch of two or more stitches is formed with a small sewing pitch smaller than the sewing pitch, the tape is stitched on the body at the normal sewing pitch.

The movement of the body is also carried out by an X-Y transfer device which moves the body pawl supporting the body along the horizontal-plane.

In order to form needle stitches of two or more stitches with a small sewing pitch, it is preferable to feed the stitches at least a length of at least a small sewing pitch (for example, within a range of a small-width sewing pitch to a small-width sewing pitch twice) When the tape feed amount is released in the sewing pitch feed direction (feeding and feeding), the tape is stitched correctly when attaching the tape sewing.

Further, the sewing pitch transfer direction is a direction in which the tape is fed in the tape feeding direction (tape feeding direction) of the tape feeding device 3, because the sewing pitch transfer direction forms the needle stitch along the longitudinal direction Path) in the X-axis direction.

A method for sewing and attaching a tape to a body of a shoe as described above is a device for sewing and attaching a tape to a body of a shoe comprising a table on which a body is set and a body pawl for supporting the body, A tape feeding device for feeding the tape to the body, and a sewing machine for sewing the tape on the body based on the sewing pattern. Further, the present invention can be applied to a tape sewing apparatus having a center presser through which a needle passes.

Thereafter, the body (LI (or RO)) is fed with a normal sewing pitch and the tape Tm is stitched.

As described above, at the start of sewing, the needle 22 is pulled to form a needle stitch of two or more stitches on the tape Tm on the body (LI (or RO)) with a small sewing pitch of about 1 mm smaller than the normal sewing pitch The center presser 23 is lowered so that the center presser 23 is lowered to a height corresponding to the thickness of the body as shown in Fig. (Tm). Whereby the tape Tm is reliably held on the body LI (or RO).

Thereafter, when sewing the tape Tm at a normal sewing pitch, the height of the center presser foot 23 is returned to the normal height, that is, the height corresponding to the body thickness + the tape thickness.

The tape T having a long length (for example, a tape Tm having a normal width) loaded on the tape rack 4 has a limitation on the length and therefore the end is overlapped with the start end of the other tape T, . Since these overlapping portions are not suitable for sewing, it is usually necessary to excise them before sewing. In the present embodiment, a gold reflective tape is attached to a tape joint (tape joint TG).

As shown in Fig. 25, the tape joint sensor 303 is provided on the upper surface of the movable block 33 via the bracket 304, and detects the tape joint TG on the tape setting side by the optical tube.

As shown in Fig. 26, the tape sensor 305 is provided on the upper surface of the movable block 33 via the bracket 306, and detects the tape T at the tape delivery side by the optical tube.

When the tape joint portion TG reaches the tape feed path on the tape feeder 3, the tape joint sensor 303 detects the light reflected from the gold tape of the tape joint TG as shown in Fig. .

With this detection, the scalpel 301 is operated in front of the tape seam TG sent by the rear roller 382 to cut the tape Tm, and again the tape seam TG, the scalpel 301 is operated and the tape Tm is cut.

That is, the tape joint sensor 303 is disposed on the upstream side in the feeding direction of the long tape with respect to the two rollers 381 and 382, and detects the joint of the tape.

The tape joint TG after cutting is delivered by the front roller 381, and the delivery of the tape is detected by the tape sensor 305 by the optical tube as shown in Fig.

That is, the tape sensor 305 is disposed on the downstream side of the two rollers 381 and 382 in the tape feeding direction, and detects the presence or absence of the tape.

When removing the tape joint TG, as shown in Fig. 27, the operator peels and removes the dispensed tape joint TG after the cutting operation.

Here, the tip of the movable block 33 on which the tape is placed is a surface which is reflected by the plating process.

The tape joint TG after cutting has three states shown in Figs. 41 (A) to 41 (C) according to the cut position (dimension) thereof.

When the tape joint TG is located exactly under the tape sensor 305, as shown in FIG. 42A, if the tape joint TG is removed by the operator, the detection of the tape sensor 305 is ON (gold tape) OFF (tape)? ON (no tape = movable block 33 surface).

When the tape sensor 305 is located behind the tape joint TG and the operator removes the tape joint TG as shown in Fig. 41B, the tape sensor 305 is detected as OFF (tape) → ON (no tape = moving block 33 surface).

41 (C), if the operator removes the tape joint TG, the tape sensor 305 is detected as OFF (tape) when the tape sensor 305 is positioned in front of the tape joint TG, → ON (gold tape) → OFF (tape) → ON (no tape = moving block 33 surface).

In any case, when the tape joint TG is removed, the tape sensor 305 is switched from OFF to ON.

In the tape stitching and attaching apparatus, the distance from the scalpel 301 of the tape feeding device 3 to the distal ends of the tape guides 34 and 35 is constant. In normal sewing, the tape Tm is stitched The tape Tm can not be made longer than the distance from the scalpel 301 to the distal end of the tape guides 34 and 35 because the tape Tm is cut to a predetermined tape length before starting to attach.

Thus, when the tape length tl scheduled to be sewn is longer than the distance from the scalpel 301 to the distal end of the tape guides 34 and 35, either the first or second extension control is selectively executed.

44, the tape Tm is released beyond the tip end of the tape guides 34, 35 to perform pre-cutting of the tape Tm at the proper position, and then the body is subjected to sewing Control.

That is, the tape feeding device 3 is retracted to the standby position in advance and the rear roller 382 is lowered (Fig. 44 (A)) before feeding the tape by the tape length tl scheduled to be sewn (B). This conveyance is performed by integrating the operation amount from the start of rotation of the rear roller 382 and monitoring the accumulated amount.

44 (C)), the front roller 381 is lowered (Fig. 44 (D)), and the tape Tm after the cutting is moved in the opposite direction (Fig. 44 (E)). The amount of feed in the opposite direction is a distance obtained by subtracting the distance cl from the scalpel 301 to the distal end of the tape guides 34 and 35 at the tape length tl. Thereby, the tip end portion of the tape Tm can be made to coincide with the tip end portions of the tape guides 34, 35.

The tape Tm is conveyed in the opposite direction so that its rear end is in contact with the guide plate 308 provided on the scalpel 301 and guided into the tape retracting hole 33a.

The maximum value of the tape length tl is determined by the distance cl from the scalpel 301 to the distal end of the tape guides 34 and 35 and the distance between the tape guides 34 and 35 in a state in which the tape feeding device 3 is in the standby position. 35 to the needle 22 from the tip of the needle. This is because, when the tape Tm is fed forward when cutting the tape Tm, there is a fear that the tape Tm interferes with the needle 22.

The second extension control shown in Fig. 45 starts sewing on the body while feeding the tape Tm without carrying out the preliminary cutting of the tape Tm so that the proper cutting position of the tape Tm is applied to the scalpel 301 And then carries out cutting.

45 (A)), the rear roller 382 is lowered while the tape feeding device 3 is placed at the feeding position (the position closest to the needle 22) To the leading end of the tape guides 34 and 35 (Fig. 45 (B)). Thereafter, the sewing is performed while the tape Tm is fed at a sewing speed without cutting the tape Tm (Fig. 45 (C) and Fig. 45 (D)).

45 (E)). When the cutting position for achieving the sewing scheduled tape length tl reaches the cutting position of the scalpel 301, the feeding is temporarily stopped and the cutting is performed by the descent of the scalpel 301 , And thereafter, the remaining sewing is performed in the same manner as in normal sewing.

The cutting of the tape may be performed by detecting that the integrated value of the transfer amount from the start of transfer of the tape Tm is equal to the tape length tl and the tip end of the tape Tm is inserted into the tip end portion of the tape guides 34, It is also possible to detect that the integrated value of the feed amount from the state in which the tape is aligned with the tape length tl has become the distance obtained by subtracting the distance cl from the tape length tl.

The feeding after the leading end of the tape Tm is aligned with the leading end of the tape guides 34 and 35 is not limited to the rear roller 382 and may be performed by the front roller 381. [

The first extension control and the second extension control allow the sewing machine control terminal 8 to select and set which one to execute in advance.

The tape feeding device 3 carries out an operation control for switching the width of the tape feeding path by widening or narrowing the tape feeding path according to the operation of the apparatus for attaching the tape Tm.

Concretely, the control box 5 (control means) controls the operation of the width correcting mechanism (width correcting device) to move the movable tape guide 34 relative to the fixed tape guide 34 The width of the tape supply path is switched by moving the tape 35 in parallel.

For example, in the tape stitching and bonding apparatus, immediately before the tape is released from the tip end portions of the tape guides 34 and 35, or just before the tape is stitched on the body (until the tape strikes the nodal portion of the body and the thread) The movable tape guide 35 is moved to a position (standby position) at which the width of the tape supply path becomes wider than the tape width (for example, about 2 needles) in which the tape is stitched to the body. By making the width of the tape supply path wider than the tape width so as not to apply friction to the tape as much as possible, the tape fed toward the body by the tape feeding device 3 is clogged in the middle of the tape feeding path, Or the like can be reduced.

If the tape is clogged in the middle of the tape feed path, there is a problem that the tape can not be supplied to the body. In addition, if the tape temporarily stops in the middle of the tape feed path, the tape is fed from the predetermined position This causes a problem and a problem that the tape can not be cut to a predetermined length.

Particularly, in the case of a soft tape having no rigidity, when the tape is fed out by the front roller 381 and the rear roller 382, the edge of the tape is tilted with the fixed tape guide 34 and the movable tape guide 35 The tape is liable to bend and the tape may be clogged.

Thus, by making the width of the tape supply path wider than the tape width, friction between the fixed tape guide 34 and the movable tape guide 35 and the tape can be suppressed, and the tape can be smoothly fed. The width of the tape supply path may be set to be, for example, 1 to 3 mm wider than the tape width, and such arrangement may be set as the stand-by position of the movable tape guide 35.

In the tape stitching and attaching apparatus, the movable tape guide 35 is moved from the standby position at a predetermined timing relating to the tape stitching, and the tape feeding path is switched so that the width of the tape feeding path becomes the tape width. By doing so, the posture of the tape fed to the body is stabilized, and the direction of the tape sewn on the body is not shifted.

Here, as the timing for moving the movable tape guide 35 to a position where the width of the tape supply path becomes the tape width by controlling the operation of the width correcting mechanism (width correcting device), the control box 5 , And the following three timings (timings A, B, and C).

Timing A: The timing at which the body and the thread are knotted by sewing only the body at the position where the tape is to be sewn in the state in which the leading end position of the tape is unfolded to the tip of the tape guide (see FIG.

Timing B: The timing at which the tape comes back to the nodal area between the body and the yarn by sewing only the body at the scheduled start position of the tape (see Fig. 22).

Timing C: Timing at which at least one needle stitch is formed (see Fig. 23) for sewing the tape to the body after sewing only the body at the scheduled start position of the tape and returning the tape to the nodal portion of the thread.

Further, the following control is performed by the control unit built in the control box 5. [

The above-described control circuit in the tape stitching and bonding apparatus is achieved by the configuration of the block diagram shown in Fig.

64, at least a ROM, a RAM, and a CPU are disposed in the control box 5 and the sewing machine 2, the tape feeding device 3, the tape rack 4, the display device 6, O circuit not shown in Fig.

The ROM is a non-volatile storage means for storing a plurality of sewing patterns and controlling various devices of the sewing machine 2 to perform a sewing operation of a predetermined sewing pattern, A control program such as a sewing-attached program for performing a predetermined tape sewing attachment operation by controlling the apparatus, default data, and the like.

The RAM is a storage means capable of writing and erasing (erasing) input information from the operation panel of the display device 6 or the bar code reader 7 and a program or data selected and read from the ROM.

The CPU constitutes a control unit for executing various programs stored in the RAM or ROM.

Next, the control of the tape stitching and attaching apparatus according to the above configuration will be described with reference to the flow chart of Fig. Further, the following control is performed by the control unit (CPU).

28, a power supply is turned on (step S1) and a subroutine for initializing the tape supply apparatus 3 (step S2) is executed.

30, the origin of the movable tape guide 35 is searched (step S201), and the movable tape guide 35 is moved to the tape width + width correction value (step S202). Subsequently, the tape supply device 3 is moved to the standby position (step S203), the front roller 381 is lowered and the rear roller 382 is raised (step S204), and the scalpel 301 is lowered S205), and the process is terminated.

28, a preparation key (not shown) displayed on the initial screen of the display screen of the sewing machine control terminal 8 is pressed (ON) following the initialization (step S2) of the tape supply device 3, (Step S3). When the ready key is pressed, the upper pusher 12 and the lower plate 11 are moved to the work setting position (the initial position shown in FIG. 5) (step S4). Subsequently, the upper pusher 12 is raised (step S5) and the positioning pin (reference pin 16) is raised (step S6).

Next, it is determined whether or not the bar code is read by the bar code reader 7 (step S7). If the bar code is read (YES in step S7), the shoe size and tape width are acquired based on the bar code Step S8). If there is a change in the width of the tape (YES in step S9), the width correction value is set to 0 (step S10), and PL (pilot) corresponding to the tape width is determined The LED lamp 48, which is a lamp, is turned on, and the other PLs are turned off (step S11). In step S9, if there is no change in width of the tape (NO in step S9), the process proceeds to step S11.

Subsequently, the movable tape guide 35 is moved to the tape width + width correction value (step S12), and the process returns to step S7.

If there is no bar code read (NO in step S7), it is determined whether or not the width correction value is input (step S13). If there is input of the width correction value (YES in step S13) Width correction value (step S14), and the process proceeds to step S12. If the width correction value is not input (NO in step S13), the process proceeds to step S15 in FIG.

Here, in step S14, the width correction value is updated, the sewing pattern is moved, and the sewing pattern is enlarged or reduced. That is, on the display screen shown in Fig. 3 of the sewing machine control terminal 8 of Fig. 1, the sewing pattern is shifted in accordance with the width correction value (-0.5 mm in the illustrated example) And further enlarges or reduces the sewing pattern.

Therefore, the display screen of the sewing machine controlling terminal 8 also serves as setting means for temporarily increasing or decreasing the tape width with respect to the set value.

It is determined whether or not the start switch 20 is ON in step S15 and the tape check subroutine is performed when the start switch 20 is ON in step S16. Is OFF, the process returns to the process of step S7.

The tape check subroutine (step S16) is executed as shown in the flowchart of Fig. 31, and it is judged whether or not the rack tape sensor 47 corresponding to the tape width is ON and the other tape sensors 47 for rack are OFF (Step S1601). When the rack tape sensor 47 corresponding to the tape width is turned ON and the other tape sensors 47 for rack are OFF (YES in step S1601), the presence or absence of the supply tape is detected (Step S1602). That is, at the beginning of sewing, it is necessary to set the leading end of the tape Tm to be in contact with the scalpel 301 in the tape supply path of the tape supply device 3 by the manual operation of the operator. In the processing for detecting the presence or absence of the supply tape, the tape seam sensor 303 provided on the tape supply path is used to determine whether or not the tape Tm is set on the upstream side of the tape supply path.

If it is determined that there is a tape by the presence or absence of the supply tape (YES in step S1602), the processing is ended (step S1603) and the processing is terminated.

If it is determined in step S1601 that the rack tape sensor 47 corresponding to the tape width is ON and the other tape sensors 47 for rack are not OFF (NO in step S1601), the process proceeds to step S1604, , And the processing is terminated.

If it is determined in step S1602 that there is no tape due to detection of the presence or absence of the supply tape (NO in step S1602), it is determined to be NG (step S1604), and the process is terminated.

29, after the tape check subroutine (step S16), whether or not the tape check is OK is determined (step S17). When the tape check is OK (YES in step S17) ) (Step S18). When the tape check is NG (NO in step S17), "no material" is displayed on the sewing machine control terminal 8, and the process returns to step S15. Further, when the tape (joint) sensor 303 checks that the material (tape) has been set (step S18), the indication "no material" on the sewing machine control terminal 8 disappears.

The AB sensor check subroutine (step S18) is executed in the flowchart shown in Fig. 32, and it is judged whether or not only one of the right and left body sensors 17 is ON (step S1801), and only one of the right and left body sensors 17 If it is ON (YES in step S1801), the status of the left and right body sensors 17 is obtained (step S1802). That is, information on which one of the left and right is ON is acquired.

40B, when the left side body sensor 17a is ON (the shielded state), the left outer body LO and the right inner body RI When the right side body sensor 17b is ON, the left inner body LI and the right outer body RO are set on the table 1. In addition,

After the process of step S1802, the process is made OK (step S1803), and the process is terminated.

If only one of the left and right body sensors 17 is not ON in step S1801 (NO in step S1801), it is determined to be NG (step S1804), and "Waiting for work setting" is sent to the sewing machine control terminal 8 And the processing is terminated. Further, when the material (body) is set and only one of the right and left body sensors 17 is turned ON, the indication of " wait for work setting " on the sewing machine control terminal 8 disappears.

29, it is determined whether or not the AB sensor check is OK (step S19), and when the AB sensor check is OK (YES in step S19), the AB sensor check subroutine (step S18) The position calculating subroutine of the IO sensor (body sensor 18) is executed (step S20). If the AB sensor check is NG (NO in step S19), the process returns to step S7.

The IO sensor position calculation subroutine (step S20) is executed in the flowchart shown in Fig. 33, and the IO sensor position calculation subroutine (step S20) is executed on the basis of the shoe size, the left and right body sensors 17 (17a, 17b) (Obtains positional information of either one of the left and right body sensors 18) (step S2001), and ends the processing.

That is, when the left side body sensor 17a is ON, the left side body sensor 18a is selected as the IO sensor and the check position is obtained. When the right side body sensor 17b is ON, Is selected as the IO sensor and the check position is obtained. 40, the left and right body sensors 17 and 18 are arranged symmetrically in this embodiment, and the check positions of the left and right body sensors 18 are distances in the vertical direction D.

29, the upper pusher 12 is lowered (step S21), the reference pin 16 is lowered (step S22), and the lower plate 11 and the upper side The pusher 12 is moved to the check position of either one of the body sensors 18a and 18b with the body sandwiched therebetween at step S23 and the IO sensor check subroutine of the left and right body sensors 18 (Step S24).

The IO sensor check subroutine (step S24) is executed by the flowchart shown in Fig. It is determined whether all of the left and right body sensors 18 are ON (step S2401). If all of the left and right body sensors 18 are not ON (NO at step S2401), either one of the right and left body sensors 18 (obtained by checking the body sensor 17) (Step S2402).

That is, in step S2402, the left body sensor 17a is turned ON and the left outer body LO or the right inner body RI is set on the table 1 in step S1802 of the AB sensor check of Fig. 32 The left outside body LO is set on the table 1 and the left side body sensor 18a is OFF and the lower portion of the radioulomb is lower in height The right body RI is set on the table 1, which is a side with a high height (wide) below the radiating bone, and the body sensor 18a on the left is ON.

In step S2402, the body sensor 17b on the right side is turned on in step S1802 of the AB sensor check (step S18) in Fig. 32, and the right outer body RO on the left inner body LI or the table 1, The right body sensor 18b is turned off and the right outer body RO having a lower height (narrow width) below the radiating bone is set on the table 1 and the right outer body RO is set on the right side The body sensor 17b of the right side body is turned on and the right side body sensor 18b is turned on and the left inner body LI is set on the table 1,

After the processing in step S2402, the tape length is determined from the state of the left and right body sensors 18, the shoe size, the state of the body sensor 17 on the left and right, and the optimum sewing pattern among the plurality of sewing patterns is selected (Step S2403), and the processing is ended (step S2404).

If all of the left and right body sensors 18 are ON in step S2401 (YES in step S2401), it is determined as NG (step S2405), and the " work setting error " is displayed on the sewing machine control terminal 8 And terminates the processing.

29, it is determined whether or not the IO sensor check is OK (step S25) following the IO sensor check subroutine (step S24). If the IO sensor check is OK (YES in step S25), the sewing subroutine (Step S26).

35 and 36 are flowcharts of the sewing subroutine (step S26). First, the rear roller 382 of the tape feeding mechanism 38 is lowered (step S2601).

If the sewing of the tape Tm is already performed, sewing is performed until the "supply end command" or "sewing end command" is read (step S2602).

If the sewing is terminated by the " supply end command " or the " sewing end command ", the movable tape guide 35 is slightly wider than the tape width + (Step S2603). This position is set as the stand-by position of the movable tape guide 35.

Next, it is determined whether or not the first supply command is newly read (step S2604).

The sewing pattern selected in S2403 includes a supply end instruction, a sewing end instruction, first and second supply instructions, a correction interval start instruction, a correction interval end instruction, and the like.

The first supply command is a command to send a tape from the cutting position of the scalpel 301 to the tip of the tape guides 24 and 25 on the tape supply path. This is a command to resume the transfer of the tape.

As shown in Fig. 43 (A), the correction section start command is included in (g-1) needle sweat and the correction section end command is included in (h) needle sweat.

If it is determined in step S2604 that there is no first supply command (NO in step S2604), it is determined whether it is a correction section start command (step S2630). If the correction section start command is received (YES in step S2630), the next needle is sewed by adding the width correction value to the movement amount of the sewing data (step S2631). Subsequently, the flow returns to step S2603.

If it is not the correction section start instruction (NO in step S2630), it is determined in step S2630 whether the instruction is the correction section end instruction (step S2632). If the correction termination instruction is issued (YES in step S2632), the next one needle is subtracted from the movement amount of the sewing data and sewed (step S2633). Subsequently, the flow returns to step S2603.

If it is not the correction section end instruction in step S2632 (NO in step S2632), the process is terminated.

Details of steps S2631 and S2633 will be described with reference to Figs. 43 (A) and 43 (B).

Fig. 43 (A) shows a sewing pattern when the width correction value of the tape is 0, and Fig. 43 (B) shows a sewing pattern when the operator operates the movable tape guide 35 to increase the tape width. All pass through the dropping point e → f → (g-1) → g → h → (h + 1) → i. If the pitch between the dropping points of the respective needles is 2 mm, the interval between (g-1) and g, h and (h + 1) is 2 mm.

For example, when the tape width of 0.5 mm is increased to the front side in the Y-axis direction, only the component in the Y-axis direction is added with the width correction value of 0.5 mm to the needle fall point g-1 before one needle of the needle drop point g, The new needle drop point (g) coordinate is determined (old g coordinate (x, y) → new g coordinate (x, y + 0.5)). If this is a correction section start command, it means that the next one needle is sewed by adding or subtracting the width correction value to the movement amount of the sewing data.

Further, when the tape width of 0.5 mm is increased to the front side in the Y-axis direction, the width correction value 0.5 mm is reduced to the needle drop point (h + 1) next to the needle drop point h and the pitch distance between h and h + mm. If this is a correction section end instruction, it means that the next one needle is sewed by adding or subtracting the width correction value to the amount of movement of the sewing data.

As a result, the control means (control box 5) divides a plurality of needle drop points (g to h) on the movable tape guide side by intervals according to the above-mentioned correction section start command and correction section end command, Corresponding to the amount of movement of the guide, a plurality of needle drop points designated in the section are moved in parallel to create a sewing pattern.

In step S2604 of Fig. 35, when the first supply command is read, a subroutine of the tape remaining amount check processing is executed (step S2605).

In the remaining tape checking subroutine shown in Fig. 37, at the time of tape remaining amount check processing, it is determined whether or not the joint flag set when the tape seam TG performed in the tape transport processing described later is detected (Step S2701). If the joint flag is not ON (NO in step S2701), the tape remaining amount checking process is terminated. If the joint flag is ON (YES in step S2701), the current value of the " length to the joint " (distance from the current position of the joint to the scalpel 301) (Step S2702).

If the length to the joint is larger (YES in step S2702), a value obtained by subtracting the length of the tape to be sewn from the current value of the length to the joint is calculated as the current value of the new " length to the joint " (Step S2703).

On the other hand, if the current value of the length to the joint is less than or equal to the length of the tape to be sewn (NO in step S2702), a "joint error" is displayed on the sewing machine control terminal 8 (step S2704) (Step S2705). That is, the tape Tm is fed by the rear roller 382 until the joint TG passes the scalpel 301, the tape Tm is cut from the rear of the joint TG, and the front roller 381 And the joint TG portion of the cut tape Tm is discharged from the front end portion of the tape supply device 3. [

The joint TG of the tape Tm discharged by the operator is removed from the tape feeder 3 (step S2707) and waits until the joint error releasing button provided on the sewing machine control terminal 8 is pressed Step S2707).

When the joint error canceling button is pressed, the "joint error" display of the sewing machine control terminal 8 is canceled. When the start switch provided on the sewing machine control terminal 8 for instructing sewing is pressed (step S2708), the joint flag is turned off (step S2709), and the tape feeding process is terminated.

Then, as shown in Fig. 35, when the remaining tape amount checking process is completed, the scalpel 301 is raised (step S2606).

Then, it is judged whether or not the length of the tape Tm to be sewn is a length exceeding the tape long or short threshold value (step S2607). The tape front-end threshold value is an upper limit value of a mechanical tape length that can be cut by the tape feeding device 3, specifically, the same value as the length from the scalpel 301 to the leading end of the tape guides 34 and 35. If the length of the tape Tm is equal to or larger than the tape leading end threshold value (NO in step S2607), the process proceeds to the first or second extension control, which will be described later.

If the length of the tape Tm is less than or equal to the tape leading end threshold value (YES in step S2607), normal sewing control is performed. That is, the rear roller 382 is lowered (step S2608), and a subroutine of the tape feeding control for feeding the tape by the predetermined tape length determined in the step S2403 of the IO sensor check (step S24) in Fig. 34 is executed Step S2609).

The tape feeding control shown in Fig. 38 is an iterative process for performing joint detection while feeding the tape Tm in units of minute lengths.

First, the tape joint sensor 303 detects the tape joint TG (step S2731). When the tape joint TG is not detected (NO in step S2731), the process proceeds to step S2734.

In addition, when the tape joint TG is detected (YES in step S2731), the length to the joint is calculated by [tape joint sensor-inter-screw distance] - [feed remaining amount (residual amount) S2732). Further, the [remaining amount of conveyance] is a value reduced by the transfer from the length of the tape to be sewn to the repeated small-length unit in the tape conveyance control. At the same time, the joint flag is set to ON (step S2733). Then, the process proceeds to step S2734.

In step S2734, the tape Tm is transported in units of micro-lengths. In this way, the [remaining amount of conveyance] is updated to a value obtained by subtracting a minute length (minute) from the current remaining amount of conveyance.

Then, in step S2735, when the newly obtained [transfer remaining amount] becomes 0 (YES in step S2735), that is, when the transfer is performed for the length of the tape to be sewn, this tape transfer control is terminated. If the remaining amount of conveyance is not yet zero (NO in step S2735), the process returns to step S2731 to repeat the tape conveyance control from the beginning.

35, when the feeding of the tape length is completed by the tape feeding control, the scalpel 301 is lowered (step S2610), the tape Tm is cut to a predetermined tape feeding length, and the front roller 381) (step S2611).

Subsequently, the tape feeding device 3 is moved to the feeding position on the needle 22 side (step S2612), and the tip of the tape Tm cut to the tape length is aligned with the tip of the tape guides 34 and 35 (Step S2613). This alignment is performed by the tape sensor 305 by means of a point where the distance from the tape sensor 305 of the tape supply device 3 to the tip of the tape guides 34 and 35 is already known, And after stopping the front roller after the already known distance (minute) has been conveyed.

36, when the tip end position of the tape Tm is aligned with the tip end of the tape guides 34 and 35, only a plurality of needles (for example, three or more needles) Sewing is performed (forming a needle sweat) (step S2614).

Then, it is determined whether or not the second supply command has been read (step S2615). When the second supply command has not been read (NO in step S2615), the process returns to step S2614 to continue sewing only the body.

When the second supply command is read (YES in step S2615), whether the setting of the timing for switching the width of the tape supply path to the tape width by moving the movable tape guide 35 from the standby position is the above-mentioned timing A (Step S2616). If the setting in the control box 5 is timing A (YES in step S2616), the process proceeds to step S2617. If the setting is not timing A (NO in step S2616) Skip to step S2618.

When the set timing is " Timing A ", the movable tape guide 35 is moved from the standby position after the thread is knotted to the body, and the width of the tape supply path is switched to the tape width (step S2617).

Then, the tape Tm is conveyed to bring the tape Tm to the nodule portion of the thread of the body (the conveyed tape Tm is conveyed to below the needle, ) Will be referred to as a tape sewing start scheduled position) (step S2618).

Next, it is judged whether or not the setting of the timing for switching the width of the tape supply path to be the tape width is the above-mentioned timing B (step S2619) by moving the movable tape guide 35 from the standby position, (YES in step S2619), the process proceeds to step S2620. If the setting is not timing B (NO in step S2619), the process skips step S2620 and proceeds to step S2621.

That is, when the set timing is " Timing B ", the movable tape guide 35 is moved from the stand-by position after the thread is knotted to the body, and the width of the tape supply path is switched to be the tape width (step S2620) .

Next, in step S2621, the center presser 23 is set to be lowered to the height of the body thickness, and then the body is moved to the XY transfer device while releasing the tape Tm to nodulate the tape Tm with the body (For example, a needle stitch of 2 or more needles is formed and the tape Tm is stitched on the body) with a small sewing pitch (about 1 mm, for example, 0.7 mm to 1.3 mm).

When forming a needle stitch of two or more stitches with a small sewing pitch, the tape Tm is unwound in the sewing pitch feeding direction by a front roller at least by a length equal to or longer than the minimum sewing pitch (for example, It is preferable to carry it in the range of 2 times).

Next, it is judged whether or not the setting of the timing for switching the width of the tape supply path to be the tape width is the above-mentioned timing C (step S2622) by moving the movable tape guide 35 from the standby position, (YES in step S2622), the process proceeds to step S2623. If the setting is not the timing C (NO in step S2622), the process skips step S2623 and proceeds to step S2624.

That is, when the set timing is " Timing C ", the movable tape guide 35 is moved from the standby position after the tape Tm is sewn, for example, The tape width is switched (step S2623).

Next, it is determined whether or not the current sewing with tape sewing is based on the second extension control (step S2624). In the above determination, the case based on the second extension control will be described later.

If the sewing with the current tape sewing is not based on the second extension control (NO in step S2624), that is, based on the normal sewing or first extension control, the process returns to step S2601, The sewing machine 382 is lowered and then sewing is continued. At this time, the center presser foot 23 is raised to return to a normal height (body thickness + tape thickness). The tape is joined by the body and the thread, and as the body is moved by the X-Y transfer device, the amount required for the needle stitch pitch is drawn.

Then, the sewing of the current tape is completed by reading a " supply end command " indicating the end of sewing on one tape or a " sewing end command "

If the " supply end command " has been read, the first supply command is read again in step S2604, and the next tape is sewn. When the " sewing end command " is read, steps S2605 to S2607 Then the sewing is finished.

As described above, when it is determined in step S2607 that the length of the tape Tm is equal to or greater than the tape short length threshold (NO in step S2607), the first or second extension control is executed.

First, when the length of the tape Tm is equal to or larger than the tape leading end threshold value, it is determined whether or not the execution of the second extension control is set in advance (step S2625).

When the first extension control is set (NO in step S2625), the tape feeder 3 is moved backward to the standby position (step S2626), and the process advances to step S2608 to move the rear roller 382 (Fig. 44 (A)).

44 (B)), the tape 301 is lowered to cut the tape Tm (step S2610: Fig. 44 (C)), and the tape Tm is cut The roller 381 is lowered (step S2611: Fig. 44 (D)), and the tape feeding device 3 is moved forward to the feeding position (step S2612).

Further, the leading end of the tape Tm is fed so as to coincide with the leading end of the tape guides 34 and 35 (step S2613). At this time, in the case of the normal sewing, the tape is transported forward, but in the first extension control, the tape Tm is transported rearward (Fig. 44 (E)).

After that, sewing is performed in the same manner as in the case of the normal sewing through the processes of steps S2614 to S2624, S2601, and S2602.

If it is determined in step S2625 that the second extension control is selected (YES in step S2625), the process advances to step S2612 to move the tape feeding device 3 to the feeding position 45 (A)).

Further, the tape is fed until the leading end of the tape Tm coincides with the leading end of the tape guides 34 and 35 (step S2613: Fig. 45 (B)) to nodulate the body and the yarn (step S2614).

After reading the second supply command, the tape Tm is brought into contact with the nodule portion of the body and the thread (Fig. 45 (C)) while adjusting the width of the tape supply path to the tape width at any selected timing ), And the tape Tm is nodded with the body at a small width of the sewing pitch (steps S2615 to S2623: Fig. 45 (D)).

If the second extension control is selected, the process proceeds to step S2627 by the determination in step S2624. That is to say, the tape Tm is fed by the tape feeding device 3 at the same feed rate as the feeding pitch in the sewing machine 2, while sewing the tape Tm, and at the same time, When the integrated value of the feeding amount of the tape Tm reaches a value obtained by subtracting the "tape length t1" - "the distance (cl) from the scalpel to the leading end of the tape guide", sewing is stopped by the sewing machine 2. At the stop position, the scalpel 301 is lowered to cut the tape Tm (step S2628: Fig. 45 (E)). Thereby, the tape Tm is cut to the tape length tl.

Then, sewing is resumed by the sewing machine 2 (step S2629), and the sewing is performed in the same manner as in the case of the normal sewing through the processes of S2601 and S2602.

29, following the sewing routine (step S26), the upper pusher 12 is raised (step S27). Thereafter, the tape supply device 3 is moved to the workpiece setting position (step S28), and the sewed-goods recovery waiting processing subroutine (step S29) is executed.

The sewing water recovery waiting subroutine is executed in the flowchart shown in Fig. 39, and acquires the body sensor 17 that has been ON from the state of the AB sensor, that is, the state of the left and right body sensors 17 (step S2801 (Step S2802). When the body sensor 17 has been turned OFF (step S2802), it is determined whether the body sensor 17 has been turned OFF (step S2802). Then, the process is terminated. Thereafter, the process returns to step S6.

29, if the IO sensor check is not OK (NO in step S25), the sewing-object collecting waiting processing subroutine (step S29) is executed, and again in step S6 Return to processing.

In the above-described embodiments, there are descriptions of the following methods and apparatuses.

The tape sewing method of the present embodiment is a method of sewing a tape obliquely to the bodies (LO, LI, RI, RO) of a shoe,

Only the size of the shoe is read by the bar code to select the tape width,

The tape of the selected width is set on the tape supply device 3,

The distinction between the left and right and the inside / outside of the body set on the table is discriminated by the body sensors 17 and 18,

A tape length corresponding to the determined body, and a sewing pattern are selected,

The tape of the selected length is supplied to the body by the tape feeding device 3 and the tape is sewn on the body by the sewing machine based on the selected sewing pattern.

In the tape stitching method, a body is set at a reference position on a table,

After discriminating the left and right distinction of the body by the body sensor, the body is discriminated by moving to the discrimination position of the inner and outer distinction based on the preset size information.

Further, the reference position is determined by three reference pins 16 appearing and disappearing from the table. As shown in Figs. 9 and 10, by selecting the combination of two reference pins (16c and 16a, 16c and 16b). The tape can be sewn in a linear direction by the combination of the reference pins of the oblique reference.

In the tape sewing method, the sewing machine sequentially reads out the pattern for identifying the inside / outside of the body and the sewing pattern after the discrimination, and operates the body pusher for pressing the body in the X and Y directions.

In the tape sewing method, the sewing machine sequentially reads out the inner and outer discrimination pattern of the body and the sewing pattern after the discrimination, and operates the body pusher for pressing the body in the XY direction (X axis direction, Y axis direction) .

The apparatus for attaching a tape sewing machine according to the present embodiment is a device for sewing a tape obliquely to the body of a shoe,

A bar code reader for reading a bar code corresponding to only the size of the shoe,

A table on which the body is set,

A body sensor for discriminating left and right and inner and outer sides of a body set on a table, a tape length selected by reading with a barcode reader, a tape length corresponding to the body discriminated by the body sensor is set, A tape feeding device for feeding a tape of the tape to the body,

And a sewing machine for selecting a sewing pattern corresponding to the body discriminated by the body sensor and sewing the tape on the body based on the selected sewing pattern.

The above-described tape stitching and attaching apparatus may further include:

A reference pin installed at a body setting position of the table and inserted into a reference hole of the body,

And a body pawl which is moved to a discrimination position for distinguishing between inside and outside by pressing the body on the basis of preset size information.

The discrimination position is a position (position shown in Fig. 40 (B)) shifted by a distance D from the setting position shown in Fig. 40 (A) to the rear side in the Y- ), The inside and outside of the body can be judged by the body sensor 18.

In the above-described tape stitching and attaching apparatus, the sewing machine sequentially reads out the pattern for internal / external discrimination of the body and the sewing pattern after the discrimination, and operates the body puck in the X and Y directions.

The body setting method of the present embodiment is a method of obliquely setting the body of a shoe to be used in the method of attaching the tape sewing to the body as described above.

When setting the body obliquely on the table, insert a reference pin into the reference hole and position it.

The body setting device of the present embodiment is an apparatus for obliquely setting the body of a shoe used for crossing the body of the shoe used in the body setting method,

And a reference pin projecting from the table with respect to a reference hole common to right and left and inside and outside in a whole size formed on the body when the body is set obliquely on the table.

In the body setting device, the reference pin is drawn into the table when a predetermined load is applied.

The apparatus for attaching a tape sewing machine according to the present embodiment is an apparatus for sewing a tape obliquely to a body of a shoe used for the body setting method,

A body setting device,

A tape supply device for supplying the tape to the body,

And a sewing machine for sewing the tape on the body based on the sewing pattern.

In the apparatus for attaching a tape sewing machine, the reference pin is ascending and descending, and is drawn into the table at the start of sewing.

In the apparatus for attaching a tape sewing machine, the reference pin does not rise on the table unless the body is pulled out from the table even after sewing is finished.

The apparatus for attaching a tape sewing machine includes a body sensor for discriminating the presence or absence of a body on a table.

As described above, according to the embodiment, only the size of the shoe can be read with the bar code to select the tape width, and from the determination of the distinction between the left and right sides of the body, the tape length corresponding to the determined body, So that it can be automatically identified.

Therefore, the kinds of barcodes can be reduced, and the right and left and inner and outer bodies of the same size can be accommodated in one basket, so that the cost can be reduced, and a small lot can be produced.

Since the reference holes h of the body are common to the left and right and the inside and outside of the whole size and the body pawls 11 and 12 and the reference pin 16 are shared, the body pawls 11 and 12, It is not necessary to change the position of the pin 16, the cost can be reduced, and a sewing error can be prevented.

In addition, since the reference pin 16 does not rise onto the table 1 unless the body is pulled out from the table 1 even after the sewing is finished, the body can be easily removed after the sewing is finished.

The present invention is not limited to the above embodiments.

46, for example, three circular holes 14c, 14d, 14e for the reference pin and two long holes 14aa, 14bb are formed in the table 1 of the sewing machine 2 Do. The round hole 14c and the two long holes 14aa and 14bb are arranged in correspondence with the vertexes of relatively large triangles in the frame of the body pawl portion 11 and three circular holes 14c, 14d, and 14e are arranged so as to correspond to apexes of relatively small triangles in the frame of the body pawl portion 11. [

At this time, the movable plate 114 disposed below the table 1 is provided with round holes 114c, 114d, 114e corresponding to the round holes 14c, 14d, 14e of the table 1, The elongated holes 114aa and 114bb corresponding to the elongated holes 14aa and 14bb of the elongated holes 11a and 11a are formed (see FIG. 47).

47, the screw bar 115 to which the reference pin 16a is attached is fixed to the elongated hole 114aa of the movable plate 114 by a nut, and the reference pin 16b is assembled The attached screw rod 115 is fixed to the long hole 114bb of the movable plate 114 by the nut and the screw rod 115 to which the reference pin 16c is attached is inserted into the circular hole 114c by a nut.

In this state, when the driving rod of the cylinder unit 113 moves up and down, the reference pin 16 ascends and descends through the movable plate 114, and the reference pin 16a is inserted into the long hole 14aa The reference pin 16b comes out of the long hole 14bb of the table 1 and the reference pin 16c comes out of the circular hole 14c of the table 1 respectively.

When three reference pins 16a, 16b and 16c are attached in this arrangement, as in the case of positioning the body shown in Figs. 9 and 10, the edge of the body LI, LO, RI, The reference pins 16b and 16c or the reference pins 16a and 16c can be inserted into the two reference holes h formed at the positions where they are folded and closed at the time of adhering.

Particularly, the reference pin 16a is adjustable in its attaching position along the long hole 114aa, and the reference pin 16b is adjustable in its mounting position along the long hole 114bb, It is possible to switch the position where the protruding and retracting from the long holes 14aa and 14bb of the table 1 can be switched.

Thus, even when the positions of the reference holes h formed in the body are different for each kind of shoes and model, for example, the attachment positions of the reference pins 16a and 16b are adjusted according to the positions of the reference holes h of the body, It becomes possible to perform positioning of various bodies.

48 and 49, the screw bar 115 to which the reference pin 16a is attached is fixed to the round hole 114d of the movable plate 114 with a nut, and the reference pin 16b And the screw pin 115 to which the reference pin 16c is attached is fixed to the round hole 114e of the movable plate 114 by a nut The mounting position of the reference pin 16 can be changed so as to be fixed to the hole 114c with a nut. Here, the screw rod 115 to which the reference pin 16c is attached is designed to protrude longer toward the lower surface of the movable plate 114 so that the reference pin 16c is positioned lower than the other reference pins 16a and 16b And is attached to the round hole 114c.

In this state, when the driving rod of the cylinder unit 113 moves up and down, the reference pin 16 ascends and descends through the movable plate 114, and the reference pin 16a moves in the circular hole 14d , The reference pin 16b comes out from the round hole 14e of the table 1, respectively. On the other hand, the reference pin 16c is adjusted to a height that does not appear upward from the round hole 14c of the table 1.

When three reference pins 16a, 16b and 16c are attached in this arrangement, as shown in Fig. 50 and Fig. 51, the center of the body LI, LO, RI, The reference pins 16a and 16b can be inserted into the two reference holes h formed at the positions covered by the tape to be positioned.

In this manner, by allowing the attachment positions of the reference pins 16a, 16b, 16c to be changed, even if the positions of the reference holes h formed in the body are different for each type of shoes or for each model, 16b, and 16c can be adjusted according to the positions of the reference pins 16a, 16b, and 16c.

That is, since the size and shape of the body and the arrangement of the tape to be sewn on the body are different depending on the type and model of the shoe, the position where the reference hole h can be formed is limited, Various types of bodies can be positioned if the positions of the reference pins 16a, 16b, 16c can be changed even if the positions of the reference holes h are different.

In the above embodiment, when a plurality of tapes to be sewn on the body are sewn, all of the tapes are sewn together as a series of operations, but any tape may be selected and stitched.

For example, FIG. 52 shows an example of a data input screen as a display screen in the sewing machine control terminal 8. As shown in FIG. Fig. 53 shows an example of a sewing screen as a display screen in the sewing machine controlling terminal 8. As shown in Fig. Both the data input screen and the sewing screen are provided with a tape sewing selection key 8a.

When the tape sewing selection key 8a on the display screen is pressed, for example, a tape sewing selection screen as shown in Fig. 54 is displayed.

The tape sewing selection screen is provided with a sewing changeover key 8b corresponding to the number of lines of the tape to be sewn, a clear key 8c, an enter key 8d, and the like.

The tape sewing selection screen shown in Fig. 54 is for sewing three tapes to the body, and has three sewing change-over keys 8b. In the tape sewing selection screen, three tapes are selected as initial settings, and three sewing change-over keys 8b are displayed as "sewing". In addition, the number of the sewing change-over keys 8b varies depending on the number of lines of the tape to be sewn.

As shown in Fig. 54, in a state in which selection and setting for sewing all three tapes have been performed, the enter key 8d is pressed to return to the sewing screen and sewing is performed, as shown in Fig. 55, So that three tapes can be sewn on the body. The tape is supplied at the needle drop point t in Fig.

56, when the sewing change-over key 8b corresponding to the second tape is pressed, for example, as shown in Fig. 56, the sewing change-over key 8b (corresponding to the second tape) ) Is switched from "sewing" to "not sewing ". Also, every time the sewing change-over key 8b is pressed, the "sewing" display and the "not sewing" display are switched in order, and sewing / not sewing can be selected. In addition, by pressing the clear key 8c, it is possible to return to the initial setting in which selection for sewing all tapes is made.

56, in a state in which the first and third tapes are sewn and the selection and setting not to sew the second tape are performed, the enter key 8d is pressed to return to the sewing screen, As shown in Fig. 57, tapes are sequentially supplied, and two tapes can be stitched on the body. 57, the tape is fed at the needle dropping point t, and at the same time, after the first tape is sewn, the section from when the third tape is fed is empty.

Thereafter, the second tape can be stitched on the body by a device in which the second tape is sewn and the first and third tapes are not sewn.

As described above, it is possible to select and sew an arbitrary tape out of a plurality of tapes to be sewn on the body, so that a plurality of tapes can be shared by a plurality of sewing machines.

For example, the sewing of three tapes may be shared by three sewing machines, and the sewing machine may be used to enrich the variation of the shoe design by changing the color, pattern, thickness and material of the tape to be sewn by each sewing machine There is a number.

In the case where sewing of three tapes is performed as a series of operations as in the prior art, there is a problem in the sewing of any one of the tapes, and when sewing again, all the tapes are stitched, It is necessary to perform sewing to attach the tape to the sewing machine, which requires troublesome work.

On the other hand, if it is possible to select and sew an arbitrary tape, only the tape having a problem can be released, and the tape can be sewn again, so that the working efficiency can be improved.

In the above embodiment, the AB sensor check and the IO sensor check of the body placed in alignment with the reference pins 16 (16a, 16b, 16c) are performed to determine the body LO on the left outside, It is automatically determined which of the body LI, the right inner body RI and the right outer body RO. However, even if the operator inputs the type of the body by using the sewing machine control terminal 8 and selects the body Do.

For example, FIG. 58 shows an example of a data input screen as a display screen in the sewing machine control terminal 8. As shown in FIG. 59 shows an example of a sewing screen as a display screen in the sewing machine controlling terminal 8. As shown in Fig. Both the data input screen and the sewing screen are display screens of the sewing machine control terminal 8 in the manual mode in which an operator inputs and selects the type of the body to which the tape is stitched, A selection key 8f, an IN selection key 8g, and an OUT selection key 8h.

The automatic determination mode of the body of the sewing machine and the manual mode selected and input by the operator can be switched by a predetermined operation at the sewing machine control terminal 8. [

Here, the operator discriminates the type of the body and describes the index to be selected.

Since the sewing surface of the tape is the upper surface and each of the bodies LI, LO, RI and RO is placed on the table 1 of the sewing machine with the front end side (shoe front side) of the body facing the rear side in the Y- By visually confirming the shape of the body positioned and placed on the table 1, it is possible to distinguish whether the body is LI or RO and whether the body is LO or RI.

For example, if the body is placed in the direction shown in Fig. 9, by pushing the " A selection key 8e " in which the mark in the same direction as the body is displayed, the left inner body LI or the right outer body RO). Similarly, for example, if the body is placed in the direction shown in Fig. 10, by pressing the " B selection key 8f " in which the mark in the same direction as the body is displayed, The body (RI) is selected.

In addition, one of small projections and small cuts is formed at the edge of the body on the side of the sole. For example, a body having a small protrusion is an inner body, and a body having a small notch is an outer body. That is, by visually confirming whether the display formed on the body is a small projection or a small notch, it is possible to distinguish whether the body is LI or RI and whether the body is LO or RO.

For example, if a small protrusion is formed on the edge of the body placed on the table 1, by pressing the "IN selection key 8g" marked with the small protrusion mark, the left inner body LI or The right inner body (RI) is selected. Likewise, if a small notch is formed on the edge of the body placed on the table 1, by pushing the "OUT selection key 8h" marked with a small notch mark, the body LO The right outer body RO is selected.

60, the worker presses the "B selection key 8f" and the "IN selection key 8g" on the sewing screen of the sewing machine control terminal 8, for example, ).

Thus, the operator can visually confirm the shape (direction) of the body placed on the table 1 of the sewing machine and the marks (small projections, small notches) formed at the edges of the body, By pressing one of the A selection key 8e and the B selection key 8f and either the IN selection key 8g or the OUT selection key 8h, (LO), the left inner body (LI), the right inner body (RI), and the right outer body (RO) among the four types of bodies mounted on the body It can be easily selected.

Next, operation control relating to the manual mode in which the operator selects and selects the type of body will be described with reference to flowcharts shown in Figs. 61 and 62. Fig.

Figs. 61 and 62 are general flow charts for tape-stitching in the manual mode.

Here, steps S401 to S414 in the flowchart of Fig. 61 correspond to steps S1 to S14 in the flowchart of Fig. 28 described above, and are related to the same operation control, and thus the description thereof is omitted .

If there is no input of the width correction value in step S413 of FIG. 61 (NO in step S413), the flow advances to step S415 in FIG.

Fig. 62 is a general flowchart following Fig. 61. In step S415, it is judged whether or not "A selection key 8e" and "B selection key 8f" are pressed (step S415) B selection key 8e "is on, the AB selection state is updated to" A "(step S416), and when the" B selection key 8f "is on, the AB selection state is updated to" B " And returns to the process of step S407.

Quot; A selection key 8e " and " B selection key 8f " are not pressed (NO in step S415) (Step S418). When the " OUT selection key 8h " is on, the IO selection state is updated to " IN " The selected state is updated to " OUT " (step S418), and the process returns to step S407.

If the "IN selection key 8g" and the "OUT selection key 8h" are not pressed (NO in step S417), it is determined in step S419 whether or not the start switch (start switch) 20 is ON, (YES in step S419), the tape is checked (step S420). If the start switch 20 is OFF (NO in step S419), the process returns to step S407.

The tape check in step S420 is the same as steps S1601 to S1604 in the flowchart of Fig. 31, so that the description will be omitted.

62, it is determined whether or not the tape check is OK (step S421). If the tape check is OK (YES in step S421), the upper pusher 12 (Step S422), the reference pin 16 is lowered (step S423), and the IO selection state and the AB selection state are checked (step S424). If the tape check is NG (NO in step S421), "no material" is displayed on the sewing machine control terminal 8, and the process returns to step S407.

Fig. 63 is a flowchart of the IO / AB selection state check (step S424). The tape length and the sewing pattern are determined from the shoe size, IO selection state, AB selection state (step S501), and the processing is terminated.

62, it is judged whether or not the IO selection state and the AB selection state are properly established (step S425), and when the IO / AB selection state is OK (YES in step S425), sewing is performed (step S426).

The sewing in step S426 is the same as that in steps S2601 to S2633 in the flowcharts of Figs. 35 and 36, and therefore, the description will be omitted.

62, following the sewing (step S426), the upper pusher 12 is raised (step S427), the tape feeding device 3 is moved to the work setting position (step S428) The water recovery waiting process (step S429) is performed.

The sewed-goods recovery standby in step S429 is the same as steps S2801 to S2803 in the flow chart of Fig. 39, so that the description will be omitted.

Then, after the sewing water recovery waiting process (step S429), the process returns to step S406.

In the general flow chart of Fig. 62, when the IO / AB selection state is not OK in step S425 (NO in step S425), the process returns to step S406 again.

As described above, when the tape is stitched on the body by the present sewing machine, the operator can easily recognize the shape (direction) of the body placed on the table 1 of the sewing machine and the display (small projection, ), Selects a selection key on which a mark corresponding to the body identified by the eye is displayed, selects one of the A selection key 8e and the B selection key 8f, the IN selection key 8g, And the OUT selection key 8h are pressed, the body placed on the table 1 is lifted up to the left outer body LO, the left inner body LI, the right inner body < RTI ID = (RI) and the right outer body (RO) can be easily selected.

That is, when the type of the body can not be automatically determined by the AB sensor check and the IO sensor check, the operator performs the selection input by the manual operation as described above, It is possible to surely select a difficult body, either the left outer body LO, the left inner body LI, the right inner body RI, or the right outer body RO.

Specifically, in the case of a body of a size larger than a general standard, a body of a small size, or a body of a special model, there is a case where the type of the body can not be automatically determined at a sensor position already installed. At this time, by switching from the automatic discrimination mode to the manual mode and performing the selection input by the manual operation described above, the type of the body can be easily selected without difficulty, and the tape can be stitched to the body.

(Modified example)

In the above-described embodiment, the tape jointed with the gold tape is used, but the tape joint may be made of silver tape or other reflective tape.

It is needless to say that the type of sensor, the number of layouts and the number of uses, the configuration of the tape supply device, and the like are optional, and the detailed structure and the like can be appropriately changed.

As the positioning member, a positioning member having a shape (shape) may be provided instead of a pin-shaped positioning member.
