If dropping on cloth band feed path, from making rear conveying roller 382, the state (Figure 17) carried by cloth band, make piston-cylinder unit 335 action as shown in figure 18, piston rod 336 is declined, then union lever 332 is taking the 2nd support axle 331 in centre portion as fulcrum clockwise oscillation. Thus, via long hole 333 and engagement pin 398, the bracket 396 of rear side is moved upward, makes the support 383 integrated with bracket 396 taking the support axle 385 of central authorities as fulcrum counter-clockwise swing. Thus, become following state, that is, rear conveying roller 382 rises from cloth band feed path, and meanwhile, front conveying roller 381 drops on cloth band feed path, is carried by cloth band.

The sewing action of the cloth band Tm for main cloth LI (or RO) of this cloth band apparatus for sewing, starts as shown in Figure 21, Figure 22, Figure 23.

Under being supplied the sewing beginning state before cloth band Tm to main cloth LI (or RO), as shown in figure 21, when sewing beginning, main cloth LI (or RO) makes seam pin 22 run through and is at least more than or equal to 3 times, utilize reach the standard grade NT and the rolling off the production line from still supply that are inserted into seam pin 22, at main cloth LI (or RO) upper formation line mark, make knotting of rolling off the production line.

Then, when starting to main cloth LI (or RO) upper supply cloth band Tm, as shown in figure 22, front conveying roller 381 is rotated, cloth band Tm is supplied to below seam pin 22, with seam pin 22 with the NT that reaches the standard grade being connected on main cloth LI (or RO) to connecing. In addition, Tm1 be front once stitch into cloth band.

Then, as shown in figure 23, utilize X-Y feeding device that main cloth LI (or RO) is moved along the cloth band direction of the supply, and, by making front conveying roller 381 rotate and carry cloth band, thus on cloth band Tm on main cloth LI (or RO), seam pin 22 is run through and is more than or equal to 2 times, utilization is rolled off the production line cloth band Tm and main cloth LI (or RO) is sewed up.

Now, make X-Y feeding device action, with according to common sewing spacing (such as, 2mm��2.5mm) compare little about 1mm (such as, 0.7mm��1.3mm) little width sewing spacing carry main cloth, further, make electric motor M1 action so that the cloth band amount of feed now becomes and little width sewing spacing equivalent or and the amount of feed of little width sewing 2 times of spacing between the amount of feed. In order to make the cloth band amount of feed of this reality change along with the characteristic (hardness, flexible, slickness) of the cloth band used so that the setting amount of feed of electric motor M1 can carry out setting in display unit 6 and change.

Then, carry main cloth LI (or RO) with common sewing spacing, and cloth band Tm is sewed.

As noted above, when sewing beginning, seam pin 22 is run through, with the little width of about 1mm little compared with common sewing spacing sewing spacing, when cloth band Tm on main cloth LI (or RO) is formed the line mark being more than or equal to 2 pins, as shown in figure 24, be equivalent to the height of main fabric thickness amount to make middle presser feet 23 drop in the way of, middle presser feet 23 is declined, to main cloth LI (or RO) upper pressing cloth band Tm. Thus, main cloth LI (or RO) reliably keeps cloth band Tm.

Then, when with common sewing spacing sewing fabric band Tm, make the height of middle presser feet 23 return to common height, that is, with the height that main fabric thickness+cloth band amount of thickness is suitable.

The strip cloth band T (the cloth band Tm of such as bandpass) being placed on cloth band stand 4, owing to length exists restriction, institute so that end is overlapping with the top of other cloth band T, by the connection use such as bonding. Owing to this overlap part is not suitable for sewing, so usually must excise before sewing. In the present embodiment, cloth band seam (cloth band seam) TG is pasted with golden reflection band.

As shown in figure 25, cloth band seam sensor 303 is arranged on the upper surface of moveable block 33 via bracket 304, utilizes phototube to arrange side at cloth band and is detected by cloth band seam TG.

As shown in figure 26, cloth belt sensor 305 is arranged on the upper surface of moveable block 33 via bracket 306, utilizes phototube to send side end at cloth band and is detected by cloth band T.

If cloth band seam TG arrives the cloth band feed path on cloth band feedway 3, then as shown in figure 25, the light reflected by the golden band of cloth band seam TG is detected by above-mentioned cloth band seam sensor 303.

By this detection, in the front side of the cloth band seam TG carried by rear conveying roller 382, making cutting knife 301 action, cut off cloth band Tm, after utilization, the rear side of the cloth band seam TG that conveying roller 382 is carried, makes cutting knife 301 action again, cuts off cloth band Tm.

That is, cloth band seam sensor 303 is relative to 2 conveying rollers 381,382, is configured in the transport direction upstream side of the cloth band of strip, the seam of cloth band is detected.

Cloth band seam TG after cut-out is sent by front conveying roller 381, as shown in figure 26, by utilizing the cloth belt sensor 305 of phototube sending of cloth band to be detected.

That is, cloth belt sensor 305 is configured in the downstream side of the transport direction of cloth band relative to 2 conveying rollers 381,382, detects with or without cloth band.

When cloth band seam TG is removed, as shown in figure 27, operation personnel take out, with finger, the cut-out that is sent after cloth band seam TG and removed.

Here, the front end of the moveable block 33 of mounting cloth band T is the surface being undertaken by electroplating processes reflecting.

Cloth band seam TG after cut-out cuts off the difference of position (size) along with it and produces this three state of Figure 38 (a) to Figure 38 (c).

Figure 38 (a) is that cloth band seam TG is just positioned at the situation below cloth belt sensor 305, now, if operation personnel remove cloth band seam TG, then the detection of cloth belt sensor 305 switches to, and connects (gold band) �� disconnection (cloth band) �� connect (without cloth band=moveable block 33 surface).

Figure 38 (b) is the situation that cloth belt sensor 305 is positioned at cloth band seam TG rear, now, if operation personnel remove cloth band seam TG, then the detection of cloth belt sensor 305 switches to, and disconnects (cloth band) �� connection (without cloth band=moveable block 33 surface).

Figure 38 (c) is the situation that cloth belt sensor 305 is positioned at cloth band seam TG front, now, if operation personnel remove cloth band seam TG, then the detection of cloth belt sensor 305 switches to, and disconnects (cloth band) �� connection (gold band) �� disconnection (cloth band) �� connect (surperficial without cloth band=moveable block 33).

In arbitrary situation, if removing cloth band seam TG, then cloth belt sensor 305 all produces the switching of disconnection �� connection.

In addition, in step S2402, in the step S1802 of AB sensor inspection assisting workflows (step S18) of Figure 32, the main cloth sensor 17b on right side connects, and when being provided with left inside side main cloth LI or the main cloth RO in right outside side at auxiliary table 1, when main cloth sensor 18b on right side disconnects, the main cloth RO in right outside side of (narrower width) that the height below ankle is lower is arranged on auxiliary table 1, in addition, connect at the main cloth sensor 17b on right side, when the main cloth sensor 18b on right side connects, the main cloth LI in left inside side of the height below ankle higher (wider width) is arranged on auxiliary table 1.

Then, after the process of step S2402, state according to the main cloth sensor 17 about the state shoe size of the main cloth sensor 18 of left and right, determine cloth strip length, and in multiple tailoring pattern, select best tailoring pattern (step S2403), as normal (step S2404), end process.

In addition, in step S2401, when the main cloth sensor 18 of left and right is all connected (step S2401, yes), as exception (step S2405), display unit 6 shows " workpiece setting is abnormal ", and end process.

In Figure 29, check after (step S24) continue IO sensor, IO sensor is checked whether and normally judges (step S25), (step S25 in the IO normal situation of sensor inspection, it is), carry out sewing (step S26) based on the tailoring pattern selected.

In the schema of the sewing (step S26) shown in Figure 35, till next " the supply order of cloth band " or " sewing finishing order ", carry out usually sewing (step S2601), to being whether that the supply instruction of cloth band judges (step S2602), (the step S2602 when cloth band supplies instruction, it is), cloth band seam sensor (cloth belt lacing sensor) 303 being checked (step S2603), judging (step S2604) whether there is cloth band seam (cloth belt lacing) TG.

In addition, in step S2602, if not being cloth band supply instruction (step S2602, no), then end process.

In step S2604, (step S2604 when cloth band seam (cloth belt lacing) TG, no), butt seam marks whether to carry out judging (step S2605) for connecting, if splice marks is not connect (step S2605, no), cutter (cutting knife 301) is then made to rise (step S2606), rear conveying roller 382 is declined (step S2607), to check cloth strip length amount conveying cloth band T (step S2608) of the regulation determined in the step S2403 of (step S24) at the IO sensor of Figure 34.

Then, make cutter (cutting knife 301) decline (step S2609), cloth band T is cut off with specified length, makes front conveying roller 381 decline (step S2610).

Then, in order to make main cloth and suture knotting, and on main cloth, only sew a few pin (such as, it is more than or equal to 3 pins) after (step S2611), before utilizing, conveying roller 381 carries cloth band T, makes the knotting part of cloth band T and main cloth and suture to connecing (step S2612). The cloth band of conveying is transported to below seam pin, is the position that can carry out with main cloth sewing. The cloth band T of this position is set to the sewing of cloth band and starts predetermined position.

As noted above, under sewing original state, cutter (cutting knife 301) is declined, and front conveying roller 381 is declined, operation personnel supply the cloth band T of specified length.

Then, in order to make cloth band and the knotting of main cloth, and cloth band T is extracted out to transport direction with the sewing spacing specified, sew spacing (about 1mm, such as, 0.7mm��1.3mm) with little width simultaneously and sew a few pin (step S2613). In addition, for sewing spacing feeding direction, in order to when sewing the cloth band of straight line shape on the main cloth of shoes, (X-axis direction) forms line mark along its length, and is formed as cloth band feeding direction (cloth band feed path) the i.e. X-axis direction of cloth band feedway 3.

Then, after making conveying roller 382 decline (step S2615) afterwards continue sewing. Cloth band T and main cloth are combined by suture, by utilizing feeding (upper presser feet 12, lower plate 11) to make main cloth move, thus constantly pull out the amount needed for line mark spacing. Then, again return the process of step S2601.

In addition, in step S2604, (step S2604 when there is cloth band seam TG, it is), it is set to splice marks (joint mark) connect (step S2616), the length till seam is set to C (be fixing from the length of cloth band seam sensor 303 to cutting knife 301) (step S2617).

Then, whether to, length C > cloth strip length till cloth band seam TG judges (step S2618), if not being length C > cloth strip length (the step S2618 till cloth band seam TG, no), in the display frame of display unit 6, then show seam mistake (joint mistake) (step S2619), as shown in figure 26, the cloth band comprising cloth band seam TG is discharged (step S2620).

Then, as shown in figure 27, state according to cloth belt sensor 305, whether the cloth band after detection discharge is removed (step S2621), (step S2621 in the removed situation of cloth band, it is), by the not shown seam false solution of display in the display frame of display unit 6 except (step S2622), wait the pressing (step S2623) of SW to be launched (beginning switch) 20. Then, it is set to splice marks disconnect (step S2624), again returns the process of step 2606.

In addition, whether the cloth band after the discharge of step S2621 is removed, and differentiates according to the switching state of the detection of cloth belt sensor 305. As shown in Figure 38 (a)��(c), in arbitrary situation, if cloth band is removed, then the detection of cloth belt sensor 305 becomes the state of " disconnect �� connect ", by this switching state is detected such that it is able to be judged as that the cloth band after discharging is removed.

In addition, in step S2605, if splice marks is for connecting (step S2605, yes), then enter the process of step S2618.

In addition, in step S2618, if the length C > cloth strip length till cloth band seam TG (necessary cloth strip length) (step S2618, it is), then by the length till cloth band seam TG, it is set to the length-Bu strip length (step S2625) till cloth band seam TG, again returns the process of step 2606.

As noted above, the detection of cloth band seam TG utilizes cloth band seam sensor 303 to carry out at the upstream side of cloth band feed path, compared with necessary cloth strip length, without waste ground supply cloth band.

In Figure 29, after sewing (step S26), presser feet 12 is made to increase (step S27), then, cloth band feedway 3 is moved (step S28) to workpiece setting position, carries out pending (step S29) such as sewing object recovery.

Reclaim in the sewing object shown in Figure 36 in the schema waiting (step S28), state according to AB sensor, namely, the state of the main cloth sensor 17 of left and right, obtain the main cloth sensor 17 (step S2801) connected, wait that the main cloth sensor 17 one-tenth connected is off (step S2802), end process.

Then, again return the process of step S6.

In addition, in Figure 29, the inspection of IO sensor is not (step S25, no) in normal situation in step s 25, enters step S29.

As noted above, as the controlling box 5 of control unit, make 2 conveying rollers 381,382 rotary actuation, cutting knife 301 is moved up and down.

Then, control unit 5 is after cloth band seam sensor 303 detects the seam of cloth band, above-mentioned cutting knife 301 is utilized to cut off the cloth band of any length comprising cloth band seam, then, utilize the front conveying roller 381 in the transport direction downstream side being configured in above-mentioned cloth band, the cloth band of any length comprising cloth band seam after cut-out is downstream sent side.

In addition, cloth band self is formed by the material of the not reflected light such as leather or cloth, as the seam TG of the moveable block 33 after the electroplating processes of the feed path of supply cloth band and cloth band, being formed by reflecting materials such as the plastic material reflected by light or coating materials, seam TG pastes or sews on cloth band. Cloth belt sensor 305 be configured to relative with feed path, and the reflection-type sensor that reflecting material is detected.

In addition, the cloth band of any length comprising cloth band seam after cutting off, according to the change of the detection signal of cloth belt sensor, is removed this situation from feed path and detects by above-mentioned control unit 5.

That is, if cloth band is removed, then the detection of cloth belt sensor 305 becomes the state of " disconnect �� connect ", by being detected by this switching state such that it is able to be judged as that the cloth band discharged is removed. In addition, having and only make a conveying roller switching mechanism 330 optionally crimped with cloth band in 2 conveying rollers, conveying roller switching mechanism 330 is controlled by control unit 5, by the downstream side conveying of cloth band.

Above, according to implementing the cloth band carrying device (cloth band delivering mechanism portion) 38 of mode and cloth band apparatus for sewing, 1 electric motor M1 is utilized to drive 2 conveying rollers 381,382, in 2 conveying rollers 381,382,1 conveying roller is only made optionally to crimp with cloth band, cloth band T is sent, and therefore, the stretching of cloth band T is less. In addition, owing to directly not utilizing travelling belt to link 2 conveying rollers 381,382, it is possible to configure cutting knife 301 between 2 conveying rollers 381,382, it is possible to easily carry out the discharge of cloth band T. In addition, as long as carrying 1 electric motor M1, it is possible to realize the miniaturization of cloth band carrying device 38.

In addition, owing to making pressing lever 302 move up and down together with cutting knife 301, pressing lever 302 presses cloth band T, it is possible to prevent from making cloth band T offset when the moving back and forth of cloth band feedway 3.
