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

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.

22, when the tape Tm is supplied to the body LI (or RO), the front roller 381 is rotated to feed 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 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 transfer device operates so that the body is transferred to a small sewing pitch of about 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 sewing pitch (equal amount) or the amount of feeding twice the sewing pitch of the small width. Since the actual tape feed amount varies depending on the characteristics (hardness, elongation, slipperiness) of the tape to be used, the setting transfer amount by the motor M1 can be changed by the display device 6 .

Thereafter, the body (LI (or RO)) is fed at a normal sewing pitch and the tape Tm is sewn together.

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 length of the long tape T (for example, the tape Tm having a normal width) loaded on the tape rack 4 is limited to the start end of another tape T They are used by being bonded together by adhesion or the like. Since these overlapping portions are not suitable for sewing, it is usually necessary to cut 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 through the bracket 306, and detects the tape T at the tape delivery end 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. .

By this detection, the tape Tm is cut by the operation of the scalpel 301 in front of the tape joint TG conveyed by the rear roller 382, and the tape joint TG , The scalpel 301 is operated to cut the tape Tm.

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.

In the case of removing the tape joint TG, as shown in Fig. 27, the operator peels and removes the fed tape edge TG after cutting.

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

The tape joint TG after cutting has three states shown in Figs. 38 (a) to 38 (c) according to the cut position (dimension) thereof.

38A shows a case where the tape seam TG is located under the tape sensor 305 and the tape sensor 305 is detected when the operator removes the tape seam TG at this time Tape)? OFF (tape)? ON (no tape = movable block 33 surface).

38 (b) shows a case where the tape sensor 305 is located behind the tape joint TG. When the operator removes the tape joint TG, the detection of the tape sensor 305 is switched from OFF (tape) to ON (No tape = movable block 33 surface).

38 (c) shows a case in which the tape sensor 305 is positioned in front of the tape joint TG. When the operator removes the tape joint TG, the detection of the tape sensor 305 is switched from OFF (tape) to ON Gold tape)? OFF (tape)? ON (no tape = movable block 33 surface).

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

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

39, 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), and stores input information from the operation panel of the display device 6 or the barcode 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).

In the general flow chart (Fig. 28) with tape sewing, first, power is turned on (step S1) and the tape supply device 3 is initialized (step S2).

30 is a flowchart of initialization (step S2) of the tape supply device 3, in which the origin of the movable tape guide 35 is searched (step S201), and the movable tape guide 35 is set (Step S202). Subsequently, the tape supply device 3 is moved to the standby position (step S203), the front roller 381 is lowered, the rear roller 382 is raised (step S204), and the cutter (Step S205), and the process is terminated.

In the general flow chart of Fig. 28, following the initialization of the tape supply device 3 (step S2), waiting for depression of an unillustrated preparation key displayed on the initial screen of the display screen of the display device 6 Step S3). When the ready key is pressed, the upper pusher 12 and the lower plate 11 are moved to the work setting position (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, the presence or absence of the bar code reading by the bar code reader 7 is determined (step S7). If there is the bar code reading (YES in step S7), the shoe size and tape width are acquired based on the bar code S8). If there is a tape width change (YES in step S9), the width correction value is set to 0 (step S10). Then, a PL corresponding to the tape width The LED lamp 48 is turned on, and the other PLs are turned off (step S11). If it is determined in step S9 that there is no change in the tape width (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 barcode reading (NO in step S7), it is determined whether or not a width correction value is input (step S13). If there is input of a width correction value (YES in step S13) The correction value is updated (step S13), 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, in the display screen shown in Fig. 3 of the display device 6 of Fig. 1, the sewing pattern is moved corresponding to the width correction value (-0.5 mm in the illustrated example) by the operator's setting on the touch panel , And further enlarges or reduces the sewing pattern.

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

Fig. 29 is a general flow chart continued from Fig. 28. In step S15, it is determined whether or not the start switch 20 is ON. If the start switch 20 is ON (YES in step S15) (Step S16). When the start switch 20 is OFF (NO in step S15), the process returns to step S7.

The tape check subroutine (step S16) is executed as shown in the flowchart of Fig. 32, 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 start of sewing, it is necessary to manually set the tape Tm to the tape supply path of the tape supply device 3 with the leading end of the tape Tm being in contact with the scalpel 301 by manual operation of the operator. In the process of 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 in the upstream portion 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 by the presence / absence of the supply tape (NO in step S1602), the process proceeds to step S1604 and the process is terminated.

29, it is determined whether or not the tape check is OK (step S17). If the tape check is OK (YES in step S17), the AB sensor (body sensor 17) (Step S18). When the tape check is NG (NO in step S17), "no material" is displayed on the display device 6 and the process returns to step S7.

When the tape (joint) sensor 303 checks that the material (tape) has been set (step S18), the indication "no material" on the display device 6 disappears.

It is determined whether or not only one of the left and right body sensors 17 is ON (step S1801) in the flowchart of the AB sensor check (step S18) shown in FIG. 32. If only one of the right and left body sensors 17 is ON (YES in step S1801), the state of the left and right body sensors 17 is obtained (step S1802). That is, whether the left side or the right side is ON is acquired.

38A, when the left side body sensor 17a is ON, the left outer body LO and the right inner body RI are set in the sub-table 1, and in the step S1802, When the right body sensor 17b is ON, the left inner body LI and the right outer body RO are set on the sub-table 1.

Then, 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 at step S1801 (NO at step S1801), it is determined to be NG (step S1804), and the display device 6 is displayed with " And terminates the processing.

When the material (body) is set so that only one of the left and right body sensors 17 is turned ON, the indication of " wait for work setting " on the display device 6 disappears.

29, it is determined whether or not the AB sensor check is OK (step S19). If the AB sensor check is OK (YES in step S19), the IO sensor (Step S20). If the AB sensor check is NG (NO in step S19), the process returns to step S7.

It is possible to change the state of the body sensor 17 (17a, 17b) of the shoe size (left and right) to the check position of either one of the left and right body sensors 18 (Obtaining 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. 37, 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 pusher 12 are moved to the check position of either one of the body sensors 18a, 18b with the body sandwiched therebetween (step S23), and the left and right body sensors 18 are checked (step S24) .

It is determined whether all the left and right body sensors 18 are all ON in the flowchart of the IO sensor check (step S24) shown in FIG. 34 (step S2401) IO detection is performed by either one of the left and right body sensors 18 obtained by the check of 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 The body sensor 18a on the left side is turned off and the left outer body LO having a lower height (narrower width) below the radiating bone is set on the sub-table 1, The body sensor 17a on the left side is turned on and the body sensor 18a on the left side is turned on and the right inner body RI which is a side with a high height (wider width) below the radiating bone is set on the sub table 1.

In step S2402, the body sensor 17b on the right side is turned on in step S1802 of the AB sensor check (step S18) of Fig. 32, and the right outer body RO The right outer body RO is set on the subsidiary table 1 and the lower right body sensor 18b is OFF and the lower part of the lower part of the radioulomb is of a lower width The body sensor 17b on the right side is turned on and the body sensor 18b on the right side is turned on and the left inner body LI having a high height .

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

If all of the left and right body sensors 18 are ON in step S2401 (YES in step S2401), it is determined to be NG (step S2405) and "display setting error" is displayed on the display device 6 The processing is terminated.

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

(Step S2601), it is judged whether or not it is a tape supply command (step S2602), and it is judged whether or not it is a tape supply command in the flowchart of sewing (step S26) (Tape Seam TG) is present (step S2604). If it is a tape supply command (YES in step S2602), the tape joint sensor (tape joint sensor) 303 is checked (step S2603).

In step S2602, if it is not the tape supply command (NO in step S2602), the processing is terminated.

If the joint flag is not ON (NO in step S2605), it is determined whether or not the joint flag is ON (step S2605). If the joint flag is not ON (NO in step S2605) (Step S2606), the rear roller 382 is lowered (step S2607), and the predetermined tape length (minute) determined in step S2403 of the IO sensor check (step S24) (Step S2608).

Then, the cutter (the knife 301) is lowered (step S2609), the tape T is cut to a predetermined length, and the front roller 381 is lowered (step S2610).

Subsequently, in order to nodulate the thread on the body, only a plurality of needles (for example, three needles or more) are sewn on the body (step S2611), the tape T is transported by the front roller 381, T) against the nodule part of the body and the thread (step S2612). The transported tape is transported to below the needle, and it is a position where sewing with the body is possible. The tape T at this position is regarded as a tape sewing start scheduled position.

Thus, in the sewing initial state, the cutter (the knife 301) is lowered and the front roller 381 is lowered, and the operator supplies the tape T of a predetermined length.

Next, a plurality of needles are sewn at a small sewing pitch (about 1 mm, for example, 0.7 mm to 1.3 mm) while releasing the tape T in a feeding direction at a predetermined sewing pitch so as to connect the tape to the body (step S2613) . In addition, since the sewing pitch transfer direction forms the needle stitch along the longitudinal direction (X-axis direction) when the linear tape is sewn on the body of the shoe, the tape feeding direction of the tape Which is a supply path).

Thereafter, the rear roller 382 is lowered (step S2615), and the sewing is continued. The tape T is joined by the body and the thread, and the amount required for the sewing pitch is pulled out as the body is moved by the feed (upper pusher 12, lower plate 11). Thereafter, the process returns to step S2601.

If it is determined in step S2604 that there is a tape seam TG (YES in step S2604), the joint flag is turned ON (step S2616), and the length to the seam is set to C (from the tape seam sensor 303 to the scaler 301 ) Is fixed) (step S2617).

If the length C to the tape joint TG is not longer than the tape length (NO in step S2618), it is determined whether or not the length C to the tape joint TG is greater than the tape length (step S2618) A joint error is displayed on the display screen of the apparatus 6 (step S2619), and the tape including the tape seam TG is discharged as shown in Fig. 26 (step S2620).

Next, as shown in Fig. 27, whether or not the discharged tape is removed is detected as the state of the tape sensor 305 (step S2621). When the tape is removed (YES in step S2621) (Step S2622), and waits for the start SW (start switch) 20 to be pressed (step S2623). Thereafter, the joint flag is turned OFF (step S2624), and the process returns to the process of step S2606.

Whether or not the discharged tape in step S2621 has been removed is determined as the switching state of the detection of the tape sensor 305. [ As shown in Figs. 38A to 38C, when the tape is removed in any case, the detection of the tape sensor 305 is in a state of "OFF to ON", and by detecting the switching state, it is judged that the discharged tape is removed There is a number.

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

If it is determined in step S2618 that the length C to the tape joint TG is longer than the required tape length (YES in step S2618), the length to the tape joint TG is set to the tape joint TG (Step S2625), and returns to the process of step 2606. [0199]

Thus, the tape joint TG is detected by the tape joint sensor 303 on the upstream side of the tape feed path, and the tape is supplied without waste, compared with the required tape length.

29, the upper pusher 12 is raised (step S27), and then the tape feeding device 3 is moved to the work setting position (step S28) (Step S29).

The body sensor 17 which has been turned ON is acquired from the state of the AB sensor, that is, the state of the left and right body sensors 17 (step S2801), in the flowchart of the sewing water recovery standby (step S28) , Waits for the body sensor 17 to be turned OFF (step S2802), and ends the processing.

Thereafter, the process returns to step S6.

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 the control means rotates the two rollers 381 and 382 to move the scalpel 301 up and down.

Then, after the tape joint sensor 303 detects the joint of the tape, the control means 5 cuts the tape having an arbitrary length including the tape joint into the scalpel 301, A tape having an arbitrary length including the cut tape joint is fed to the downstream side by the front roller 381 disposed on the downstream side in the direction.

The tape itself is formed of a material that does not reflect light such as leather or cloth, and the jointed portion (TG) of the tape and the movable block 33 subjected to the plating process as a supply path for supplying the tape is made of plastic (TG) is attached to (adhered to) or stitched on a tape. The tape sensor 305 is a reflection type sensor that is disposed so as to face a supply path and detects a reflective material.

The control means (5) detects that a tape having an arbitrary length including the cut tape joint has been removed from the supply path by a change in the detection signal of the tape sensor.

That is, when the tape is removed, the detection of the tape sensor 305 becomes the state of "OFF → ON", and by detecting the switching state, it can be judged that the discharged tape is removed. In addition, a roller switching mechanism 330 selectively presses only one of the two rollers selectively against the tape. The control means 5 controls the roller switching mechanism 330 to transfer the tape to the downstream side.

As described above, according to the tape stitching apparatus of the embodiment, since the two rollers 381 and 382 are driven by one motor, the tape T can be fed, so that the stretching of the tape T is minimized . Since the two rollers 381 and 382 are not directly connected by a belt, the scalpel 301 can be disposed between the two rollers 381 and 382, and the tape T can be easily discharged have.

It is also possible to reliably discriminate whether or not the tape joint portion that has been cut off after removal of the tape joint portion that has been cut off by the finger after the tape joint portion is cut out by the roller toward the tip end side of the tape delivery device can be reliably determined by the change in the detection signal of the tape sensor.

(Modified example)

The present invention is not limited to the above-described embodiments.

In the above embodiments, the tape jointed with the gold tape is used, but the tape joint may be connected with a silver tape or another 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.

The present application is based on Japanese Patent Application (Patent Application No. 2011-220076) filed on October 4, 2011, which is incorporated by reference in its entirety. Also, all references cited here are taken as a whole.
