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

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).

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 limit on the length, ), And they are used by joining 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 (stuck) 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 splice TG reaches the tape feed path on the tape feeder 3, as shown in Fig. 25, the tape splice sensor 303 is reflected by the gold tape of the tape splice TG And detects light.

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 positioned exactly under the tape sensor 305 and at this time when the operator removes the tape seam TG, the detection of the tape sensor 305 is ON ) → 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.

41, at least a ROM, a RAM and a CPU are disposed inside 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).

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 the 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), 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 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 again.

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 there is no input of the width correction value in step S13 (NO in step S13), the flow advances 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 following 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 beginning of sewing, it is necessary to set the leading end of the tape Tm to the tape feeding path of the tape feeding device 3 by the manual operation of the operator so as to be in contact with the scalpel 301. In the process of detecting the presence or absence of the supply tape, the tape joint 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 by the presence / absence of the supply tape that there is a tape (YES in step S1602), the processing is ended (step S1603) and the process 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 the presence or absence of the supply tape (NO in step S1602), the process goes to NG (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.

37, when the left body sensor 17a is ON, the left outer body LO and the right inner body RI are set on 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.

In step S1801, if only one of the left and right body sensors 17 is not ON (NO in step S1801), it is determined to be NG (step S1804), and "Waiting for work setting" is displayed on the display device 6 The processing is terminated.

Further, when the material (body) is set and only one of the left and right body sensors 17 is turned ON, the indication of " Waiting 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 the 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, the left and right body sensors 17, 18 are symmetrically arranged in this embodiment, and the check positions of the left and right body sensors 18 are distances in the vertical direction D, respectively.

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 positions of either one of the body sensors 18, 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 so that the right inner body RI which is a side with a high height (wide 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 sensors 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), and is made OK (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 the tape supply command (YES in step S2602), the tape joint sensor 303 is checked (step S2603) to determine whether or not there is a tape joint TG (step S2604).

The sewing pattern selected in S2403 includes a tape supply command, a sewing end command, a tape supply command, a correction section start command, a correction section end command, and the like.

As shown in Fig. 40 (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 S2602 that there is no tape supply command (NO in step S2602), 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 one needle is sewed with the width correction value added to the amount of movement of the sewing data (step S2631). Subsequently, the flow returns to S2601.

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 it is the end of the correction section (YES in step S2632), the next one needle is sewed by adding and subtracting the width correction value from the movement amount of the sewing data (step S2633). Subsequently, the flow returns to S2601.

If the correction termination instruction is issued in S2632 (NO in step S2632), the process is terminated.

Details of steps S2631 and S2633 will be described with reference to Figs. 40 (a) and 40 (b).

40 (a) shows a sewing pattern when the width correction value of the tape is zero, and Fig. 40 (b) shows a sewing pattern in the case where 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 each needle dropping point 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 drop 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 correction section start command and the correction section end command, In response 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.

If the joint flag is not ON (NO in step S2605), it is judged whether or not the joint flag is ON (step S2606). If the joint flag is not ON (NO in step S2605) (Step S2606), the rear roller 382 is lowered (Step S2607), and the tape T is fed by the predetermined tape length 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, only the body is sewed with a plurality of needles (for example, three needles or more) (step S2611), the tape T is then transported by the front roller 381, and the tape T ) Against the nodule portion 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 worker feeds the tape T of a predetermined length by the fall of the cutter (the knife 301) and the fall of the front roller 381. [

Then, in order to connect the tape to the body, several needles are sewed at a small sewing pitch (about 1 mm, for example, 0.7 mm to 1.3 mm) while releasing the tape T (step S2613).

Thereafter, the rear roller 382 is lowered (step S2615), and then the sewing is continued. The tape T is joined by the body and the thread, and as the body is moved by the feeding (the upper pusher 12 and the lower plate 11), an amount necessary for the needle sweat pitch is pulled out. 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 301): fixed) (step S2617).

If it is determined that the length C to the tape joint TG is greater than the tape length (step S2618) and the length C to the tape joint TG is not longer than the tape length (NO in step S2618) (Step S2619), and a tape including the tape joint TG is ejected 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 step 2606 again.

Whether or not the tape discharged in step S2621 has been removed is determined as the switching state of the detection of the tape sensor 305. [ 38 (a) to 38 (c), when the tape is removed in any case, the detection of the tape sensor 305 is in the "OFF → ON" state, and by detecting the switching state, Can be judged to have been removed.

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 again.

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, following the sewing (step S26), the upper pusher 12 is raised (step S27), and the sewing water recovery standby processing is performed (step S28).

29, the tape feeding device 3 is moved to the work setting position (step S28), and the sewing water recovery waiting process (step S29) is performed.

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

Fig. 36 is a flowchart of waiting for sewing (step S28). 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) (Step S2802). If the body sensor 17 has been turned off, it is determined whether the body sensor 17 has been turned off (step S2802). When the body sensor 17 is turned off (YES in step S2802), the reference pin is raised (S2803). Then, the process is terminated. Thereafter, the process returns to step S6.
