As described in detail, the roller switching mechanism 330 has a coupling rod 332 that is coupled to the holder 383 at one end side, a second shaft 331 that rotatably supports the coupling rod 332, and a rear end of the coupling rod 332. The cylinder unit 335 is connected to each other.

When the rear roller 382 is retracted to the belt supply path to convey the belt body (FIG. 17), as shown in FIG. 18, if the cylinder unit 335 is operated, the cylinder unit 335 is operated. When the piston rod 336 is lowered, the coupling rod 832 swings clockwise with the second support shaft 331 at the intermediate portion as a fulcrum. Thereby, the rear side bracket 396 is moved upward by the long hole 333 and the fastening pin 398, and the holder 383 integrated with the bracket 396 swings counterclockwise with the center support shaft 385 as a fulcrum. Thereby, the front roller 382 is lowered by the belt supply path, and the front roller 381 is lowered to the belt supply path to convey the belt body.

The sewing operation of the tape Tm of the slit L1 (or RO) by the tape sewing device is started as shown in Figs. 21, 22, and 23.

In the initial sewing state in which the tape Lm (or RO) is supplied to the tape Tm, as shown in Fig. 21, at the time of starting the sewing, the needle 22 is passed through at least three times on the slit LI (or RO). By inserting the upper thread NT of the needle 22 and the lower thread supplied by the hook, the stitches are formed on the slit L1 (or RO) to make the upper and lower lines nodule.

Thereafter, when the supply of the tape Tm is started on the sewn piece LI (or RO), as shown in FIG. 22, the front roller 381 is rotated to supply the tape Tm to the needle 22, and to abut against the needle 22 and the slit. The upper line NT connected to the slice L1 (or RO). Among them, Tm1 is the belt body that was previously sewn.

Thereafter, as shown in FIG. 23, the slit L1 (or RO) is moved in the belt supply direction by the XY feeding device, and the front roller 381 is rotated to transport the belt body, thereby allowing the needle 22 to pass through twice or more. On the strip Tm on the slit LI (or RO), the strip Tm is sewn to the slit LI (or RO) by the upper and lower lines.

At this time, the XY feed device is operated by conveying the slits at a small width sewing pitch of 1 mm (for example, 0.7 mm to 1.3 mm) which is smaller than the usual sewing pitch (for example, 2 mm to 2.5 mm), and Belt feed at this time The amount of the motor M1 is operated so as to be a feed amount equal to a small-width sewing pitch equal to or equal to a double feed of a small-width sewing pitch. Since the actual belt feed amount varies depending on the characteristics (hardness, stretchability, and smoothness) of the belt body to be used, the setting amount for the motor M1 can be changed by the display device 6.

Thereafter, the slit piece LI (or RO) is conveyed at a usual sewing pitch and the tape body Tm is sewn.

As described above, at the start of sewing, when the needle 22 is inserted into a small width sewing pitch of 1 mm before and after the usual sewing pitch, two stitches or more are formed on the tape Tm on the slit LI (or RO). In the case of the stitches, as shown in Fig. 24, the intermediate presser foot 23 is lowered to lower the intermediate presser foot 23 to a thickness corresponding to the thickness of the slit, and the tape Tm is pressed against the slit L1 (or RO). Thereby, the tape Tm is surely held on the slit LI (or RO).

Thereafter, when the tape Tm is sewn at a normal sewing pitch, the height of the intermediate presser 23 is restored to a normal height, that is, a height corresponding to the thickness of the slit + the thickness of the tape.

The elongated strip T (for example, a generally wide strip Tm) loaded on the belt frame 4 has a limited length, so that the end is overlapped with the beginning of the other strip T, and is used by subsequent joining. This repeating portion is not suitable for sewing, so it is usually necessary to perform the cutting before sewing. In the present embodiment, the gold reflective tape body is adhered to the tape joint portion (belt joint) TG.

As shown in Fig. 25, the belt seam sensor 303 is disposed on the upper surface of the movable block 33 through the holder 304, and the belt seam TG is detected on the belt housing side by the phototube.

As shown in Fig. 26, the strip sensor 305 is disposed on the upper surface of the movable block 33 via the holder 306, and the strip T is detected at the strip end side by the phototube.

When the belt seam portion TG reaches the belt supply path on the belt supply device 3, as shown in Fig. 25, the belt seam sensor 303 detects the light reflected by the belt joint TG in the gold belt body.

By this detection, the cutter 301 is operated to cut the belt body Tm before the belt seam TG conveyed by the rear roller 382, and again after the belt joint TG conveyed by the rear roller 382 On the side, the cutter 301 is operated to cut the belt body Tm.

In other words, the belt seam sensor 303 is disposed on the upstream side in the feeding direction of the elongated belt body with respect to the two rollers 381 and 382 to detect the seam of the belt body.

The cut tape joint TG is fed out by the front roller 381, and as shown in Fig. 26, the tape body sensor 305 obtained by the phototube is used to detect the tape feed.

In other words, the belt sensor 305 is disposed on the downstream side of the belt feeding direction with respect to the two rollers 381 and 382 to detect the presence or absence of the belt.

When the belt seam TG is removed, as shown in FIG. 27, the operator removes the cut belt seam TG that has been fed by the finger and removes it.

Here, the front end of the movable block 33 placed on the tape body T is a surface that is reflected by a plating process.

According to the cutting position (size) of the tape joint TG after cutting, three states of Figs. 38(a) to 38(c) occur.

Figure 38 (a) The strap seam TG is located just below the belt sensor 305 In this case, if the operator removes the belt seam TG, the detection of the belt sensor 305 is switched to ON (gold belt body) → OFF (belt body) → ON (no belt body = movable block 33 surface) ).

38(b) When the strap body sensor 305 is located behind the belt seam TG, if the operator removes the belt seam TG, the detection of the belt sensor 305 is switched to OFF (belt) → ON (No belt = surface of movable block 33).

38(c) In the case where the strap body sensor 305 is located before the belt seam TG, if the operator removes the belt seam TG, the detection of the belt sensor 305 is switched to OFF (belt) → ON (Gold belt body) → OFF (band body) → ON (no belt body = surface of movable block 33).

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

The control circuit in the above-described tape sewing device is realized by the configuration of the block diagram shown in FIG.

In FIG. 39, at least a ROM, a RAM, and a CPU are disposed inside the control box 5, and are connected to the sewing machine 2, the belt supply device 3, the belt rack 4, and the display device through an I/O circuit (not shown). 6. Bar code reader 7.

The ROM is a non-volatile memory device, and has a plurality of sewing patterns, and has various devices for controlling the sewing machine 2 to perform a sewing operation for sewing a predetermined sewing pattern, and various devices for controlling the belt sewing device. Control program or preset data such as a sewing program with a predetermined sewing action.

The RAM is a memorable erase memory means for memorizing input information from the operation panel of the display device 6 or the bar code reader 7, or selected by the ROM. The program or material being read.

The CPU constitutes a control unit that executes various programs stored in the RAM or the ROM.

Next, the control of the belt sewn device by the above configuration will be described in accordance with the flowchart subsequent to FIG.

Among them, the following control is processed by the aforementioned control unit (CPU).

In the general flowchart (Fig. 28) in which the belt is sewn, first, the power source is turned on (step S1), and the belt supply device 3 is initialized (step S2).

Fig. 30 is a flowchart showing the initialization of the tape supply device 3 (step S2), searching for the origin of the movable belt guide 35 (step S201), and the movable belt guide 35 (belt width + width) The correction value is moved (step S202). Next, the belt 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 cutter 301 is lowered (step S205), and the processing is terminated.

In the general flowchart of FIG. 28, the tape supply device 3 is initialized (step S2), and waits for pressing of a preparation key (not shown) displayed on the initial screen of the display screen of the display device 6 (step S3). When the preparation key is pressed, the upper presser foot 12 and the lower plate 11 are moved to the workpiece placement position (the initial position shown in Fig. 5) (step S4). Next, the upper presser foot 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 read by the bar code reader 7 is read (step S7), and if there is a bar code reading (YES in step S7), the shoe size and the tape width are obtained based on the bar code (step S8). ). Next, it is determined whether there is a belt width change (step S9), and if there is a belt width change (step S9) YES), the wide correction value is set to 0 (step S10), and the LED lamp 48, which is a PL (indicator) corresponding to the width of the tape, is turned on, and the other PL is turned off (step S11). However, if there is no change in the width of the belt in step S9 (NO in step S9), the process proceeds to step S11.

Next, the movable belt body guide 35 is moved (the belt width + the width correction value) (step S12), and the process returns to the step S7 again.

Further, in step S7, if there is no bar code reading (NO in step S7), it is determined whether or not the wide correction value is input (step S13), and if there is a wide correction value input (YES in step S13), the wide area is updated. The value is corrected (step S13), and the process proceeds to step S12. However, if there is no wide-width correction value input in step S13 (NO in step S13), the process proceeds to step S15 in Fig. 29 .

Here, in step S14, the wide-width correction value is updated, and the sewing is moved, and the sewing pattern is additionally enlarged or reduced. That is, in the display screen shown in FIG. 3 of the display device 6 of FIG. 1, corresponding to the wide correction value (-0.5 mm in the illustrated example) obtained by the operator setting the touch panel. , move the sewing pattern, and even enlarge or reduce the sewing pattern.

Therefore, the display screen of the display device 6 also serves as a setting means for temporarily increasing or decreasing the width of the tape relative to the set value.

29 is a general flowchart of FIG. 28, in which it is determined in step S15 whether or not the start SW (start switch) 20 is ON, and if the start switch 20 is ON (YES in step S15), the inspection of the belt is performed (step S16). When the start switch 20 is OFF (NO in step S15), the process returns to step S7 again.

The belt inspection subroutine (step S16) is executed as shown in the flow chart shown in FIG. 32, and determines whether the belt belt sensor corresponding to the belt width is used. When the 47 is ON, the other belt body sensor 47 is OFF (step S1601), and if the belt belt sensor 47 corresponding to the belt width is ON, the other frame is When the tape sensor 47 is OFF (YES in step S1601), the presence or absence of the supply tape is detected (step S1602). In other words, the sewing start is performed by the manual work of the operator, and the belt supply path of the belt supply device 3 is placed in a state where the front end portion of the belt Tm is pressed against the cutter 301. In the process of detecting the presence or absence of the supply belt body, it is determined whether or not the belt body Tm is disposed in the upstream portion of the belt supply path by the belt joint sensor 303 provided on the belt supply path.

Next, when it is determined that there is a tape by detecting the presence or absence of the supply tape (YES in step S1602), it is set to OK (step S1603), and the processing is terminated.

In the case where the rack belt sensor 47 corresponding to the strip width is ON and the other rack belt sensor 47 is not OFF in step S1601 (NO in step S1601) It is set to NG (step S1604) and the processing is ended.

In addition, when it is determined that there is no tape by detecting the presence or absence of the supply tape in step S1602 (NO in step S1602), NG is set (step S1604), and the process is terminated.

In Fig. 29, the tape inspection is continued (step S16), it is judged whether or not the tape inspection is OK (step S17), and if the tape inspection is OK (YES in step S17), the AB sensor (sewing sensor) is performed. In the inspection of 17) (step S18), when the belt inspection NG (NO in step S17), the display device 6 displays "no material" and returns to the processing of step S7 again.

Wherein, the belt seam sensor 303 detects that the material is placed (belt) In the case of the body (step S18), the display of "no material" on the display device 6 disappears.

In the flowchart of the AB sensor inspection (step S18) shown in FIG. 32, it is determined whether only one of the left and right blade sensors 17 is ON (step S1801), and if the left and right slit sensors are used When only one of the 17 is ON (YES in step S1801), the state of the left and right slit sensor 17 is acquired (step S1802). That is, which of the left and right is ON? .

That is, in step S1802, as shown in FIG. 38A, if the left slit sensor 17a is ON, the left outer slit LO or the right inner slit RI is placed on the auxiliary platform 1, and further, if right When the square slit sensor 17b is ON, the left inner slit LI or the right outer slit RO is placed on the auxiliary platform 1.

Next, after the process of step S1802, it is set to OK (step S1803), and the process is terminated.

In the case where only one of the left and right slit sensor 17 is not ON (NO in step S1801), NG is set in step S1801 (step S1804), and "waiting to place the workpiece" is displayed on the display device 6. And the end of the process.

Here, if the material (sewing) is placed and only one of the left and right slit sensors 17 is set to ON, the display of "waiting for the workpiece" on the display device 6 disappears.

In FIG. 29, the AB sensor check is continued (step S18), it is judged whether the AB sensor check is OK (step S19), and if the AB sensor checks OK (YES of step S19), the IO sensor is performed. (Position sensor 18) Position calculation (step S20), if the AB sensor checks NG (NO in step S19), the process returns to step S7 again.

In the flowchart of the IO sensor position calculation (step S20) shown in FIG. 33, the slits for the left and right sides are obtained from the state of the shoe size/left and right slit sensor 17 (17a, 17b). The pattern No. of the inspection position of any of the devices 18 or the coordinates (the position information of any of the left and right slit sensor 18) is obtained (step S2001), and the processing is terminated.

That is, if the left slit sensor 17a is ON, the left slit sensor 18a is selected as the IO sensor, and the inspection position is obtained, if the right slit sensor 17b is ON. The slit sensor 18b on the right side is selected as an IO sensor, and the inspection position is obtained. As shown in Fig. 37, in the present embodiment, the left and right blade sensors 17, 18 are symmetrically arranged, and the inspection positions of the left and right blade sensors 18 are the distances in the longitudinal direction D.

In FIG. 29, the IO sensor position calculation is continued (step S20), the upper presser foot 12 is lowered (step S21), the reference pin 16 is lowered (step S22), and the lower plate 11 and the upper presser foot 12 are placed together with the clip. The slit sheets therebetween are moved together to the inspection positions of the left and right slit sensor 18s (18a, 18b) (step S23), and the left and right slit sensors 18 are inspected (step S24).

In the flowchart of the IO sensor inspection (step S24) shown in FIG. 34, it is determined whether or not the left and right blade sensors 18 are all ON (step S2401), and if not all of them are ON (NO of step S2401), The left and right blade sensors 18 obtained by the AB sensor inspection (inspection of the slit sensor 17) perform IO detection (step S2402).

That is, in step S2402, in the step S1802 of the AB sensor inspection (step S18) of Fig. 32, if the left slit sensor 17a is ON and the left outer slit LO is placed on the auxiliary platform 1, Or right inner slit RI, left The slit sensor 18a is OFF, and the left outer slit LO having a lower height (wide width) under the ankle is placed on the auxiliary platform 1, and the left slit sensor 17a is ON, left The slit sensor 18a is ON, and the right side slit RI having a higher height (wide width) under the ankle is placed on the auxiliary platform 1.

Further, in step S2402, in the step S1802 of the AB sensor inspection (step S18) of FIG. 32, if the right slit sensor 17b is ON and the left inner slit LI is placed on the auxiliary platform 1, In the right outer side slit RO, the right side slit sensor 18b is OFF, and the auxiliary platform 1 is provided with a lower right (wide width) right outer side slit RO under the ankle, and in addition, the right side slit piece The sensor 17b is ON, the right slit sensor 18b is ON, and the auxiliary platform 1 is provided with a left inner slit LI of a higher height (wide width) under the ankle.

Next, after the process of step S2402, the state of the left and right blade sensors 18/shoe size/the state of the left and right blade sensors 17 is determined, and the length of the tape is determined, and the optimum among the plurality of stitch patterns is selected. The sewing pattern (step S2403) is set to OK (step S2404), and the processing is ended.

In the case where the left and right blade sensors 18 are all turned ON (YES in step S2401), NG is set (step S2405), and the "workpiece placement abnormality" is displayed on the display device 6, and the processing is terminated.

In FIG. 29, the IO sensor check is continued (step S24), it is judged whether the IO sensor check is OK (step S25), and if the IO sensor checks OK (YES of step S25), it is selected according to The pattern is sewn to perform sewing (step S26).

In the flowchart of the sewing (step S26) shown in FIG. 35, the usual sewing is performed to the next "belt supply command" or "sewing end command". (Step S2601), it is determined whether or not the tape supply command is issued (step S2602), and if the tape supply command is issued (YES in step S2602), the tape seam sensor (belt joint sensor) 303 is inspected ( In step S2603), it is determined whether or not there is a belt seam (belt joint) TG (step S2604).

However, in step S2602, if the supply instruction is not the tape supply (NO in step S2602), the processing is terminated.

In step S2604, if there is no body seam (belt joint) TG (NO in step S2604), it is determined whether or not the seam flag is ON (step S2605), and if it is not the seam flag ON (NO of step S2605) The cutter 301 is raised (step S2606), and the rear roller 382 is lowered (step S2607) to determine the predetermined belt body in step S2403 of the IO sensor inspection (step S24) of FIG. The tape body T is conveyed to the length (step S2608).

Next, the cutter 301 is lowered (step S2609), the tape body T is cut into a predetermined length, and the front roller 381 is lowered (step S2610).

Next, in order to make the slit and the wire nodule, only the number of stitches (for example, three or more stitches) is sewn on the slit (step S2611), the front roller 381 transports the tape T, and the tape T is abutted against the nodule of the slit and the thread. Part (step S2612). The belt system being conveyed is sent to the needle under the position where it can be sewn to the seam. The tape T at this position is set to a predetermined position at which the tape body starts to be sewn.

As described above, in the initial state of sewing, the cutter 301 is lowered, and the front roller 381 is lowered, and the operator is supplied with the tape T of a predetermined length.

Next, in order to make the band and the slit piece nodule, the tape body T is continuously fed in a direction in which the tape sewing is fed in a predetermined sewing pitch, and the slit is slit at a small width. The number of stitches is sewn at a pitch (1 mm front and rear, for example, 0.7 mm to 1.3 mm) (step S2613). In the sewing pitch feeding direction, when the stitches of the shoe are sewn with a linear belt body, since the stitches are formed along the longitudinal direction (X-axis direction), the belt body formed in the belt supply device 3 is inserted. The direction (the belt supply path) is the X-axis direction.

Thereafter, the rear roller 382 is lowered (step S2615) and sewing is continued. The tape T is combined by the slit and the wire, and the slit is moved by the feeding (the upper presser 12 and the lower plate 11), whereby the amount required for the stitch pitch is pulled out. Then, it returns to the process of step S2601 again.

Further, if there is a body seam TG in step S2604 (YES in step S2604), the seam flag (joint flag) is turned ON (step S2616), and the length until the seam is set to C. (The length from the belt seam sensor 303 to the cutter 301 is fixed) (step S2617).

Next, it is determined whether the length C to the tape seam TG is > the tape length (step S2618), and if not the length C to the tape body joint TG > the tape length (NO in step S2618), on the display device 6 The display screen displays a seam error (joint error) (step S2619), and as shown in Fig. 26, the belt body including the belt seam TG is discharged (step S2620).

Next, as shown in FIG. 27, it is detected in the state of the tape sensor 305 whether or not the discharged tape has been removed (step S2621), and if the tape has been removed (YES in step S2621), the display device will be displayed. The seam error (not shown) displayed on the display screen of 6 is released (step S2622), and the pressing of the start SW (start switch) 20 is waited for (step S2623). Thereafter, the seam flag is set to OFF (step S2624), and the process returns to step S2606 again.

Here, whether or not the tape body discharged in step S2621 has been removed is determined in the detection switching state of the tape sensor 305. As shown in FIGS. 38(a) to (c), when the tape body is removed in any case, the detection system of the tape sensor 305 is in an "OFF→ON" state, and by detecting the switching state, it can be judged. The discharged tape has been removed.

Further, in step S2605, if the seam flag is ON (YES in step S2605), the process proceeds to step S2618.

In addition, in step S2618, if the length C to the tape seam TG is the tape length (the required tape length) (YES in step S2618), the length until the tape seam TG is set to the tape length. The length of the body seam TG - the length of the belt body (step S2625), returns to the process of step S2606 again.

As described above, the detection of the belt seam TG is performed on the upstream side of the belt supply path by the belt seam sensor 303, and the belt body is not wasted compared with the required belt length. .

In Fig. 29, the sewing is continued (step S26), the upper presser foot 12 is raised (step S27), and thereafter, the tape supply device 3 is moved to the workpiece setting position (step S28), and the sewing material recovery waiting process is performed (step S29). ).

In the flowchart of the sewing material recovery waiting (step S28) shown in Fig. 36, the stitch sensor that was originally ON is obtained from the state of the AB sensor, that is, the state of the left and right slit sensor 17 17 (step S2801), the sheet sensor 17 that has been turned ON is turned OFF (step S2802), and the processing is terminated.

After that, the process returns to the process of step S6 again.

Further, in Fig. 29, if the IO sensor check is not OK in step S25 (NO in step S25), the process proceeds to step S29.

As described above, the control box 5 as a control means rotationally drives the two rollers 381 and 382 to move the cutter 301 up and down.

Next, after the belt seam sensor 303 detects the seam of the belt body, the control means 5 cuts the belt body of any length including the belt seam by the cutter 301, and then arranges it in the foregoing The front roller 381 on the downstream side in the feeding direction of the belt conveys the cut belt of any length including the seam of the belt to the downstream side.

Further, the belt body itself is formed of a material such as leather or cloth that does not reflect light, and the movable portion 33 and the seam TG of the belt body which are plated as the supply path of the supply belt body are plastics that reflect light. A reflective material such as a material or a coating material is formed, and the joint TG is attached or sewn to the belt. The belt sensor 305 is configured to face the supply path and to detect the reflective sensor of the reflective material.

Next, the control means 5 detects that the cut strip of any length including the seam of the strip has been removed by the supply path by the change of the detection signal of the strip sensor.

That is, when the tape body is removed, the detection of the tape sensor 305 is in an "OFF→ON" state, and by detecting the switching state, it can be determined that the discharged tape has been removed. Further, a roller switching mechanism 330 that selectively presses only one of the two rollers to the belt body is provided, and the control means 5 controls the roller switching mechanism 330 to send the belt body to the downstream side.

As described above, the belt stitching device of the embodiment drives the two rollers 381 and 382 by one motor, and the tape body T is sent out. Therefore, the tape body T can be stretched less. In addition, since the two rollers 381 and 382 are not directly skinned Since the belts are coupled to each other, the cutter 301 can be disposed between the two rollers 381 and 382, and the discharge of the belt T can be easily performed.

In addition, after the cut seam portion of the belt body is sent out to the front end side of the belt feeding device by the roller, the change of the detection signal of the belt sensor can be used to positively determine whether The finger has removed the portion of the seam that was cut.
