Now, make the action of X-Y feed arrangement, to make spacing (such as according to common, 2mm ~ 2.5mm) compare little about 1mm (such as, 0.7mm ~ 1.3mm) little width make spacing and carry main cloth, further, make motor M1 action, become to make the strap amount of feeding now and stitching spacing equivalent or and the amount of feeding of 2 times of stitching spacing between the amount of feeding.In order to make the strap amount of feeding of this reality change along with the characteristic (hardness, flexible, smoothness) of the strap used, making the setting amount of feeding of motor M1 can carry out setting in display unit 6 and changing.

Namely, when making strap on the main cloth of shoes, main cloth is formed and makes after beginning is at least more than or equal to the stitching of 3 pins, the beginning precalculated position of making of strap is supplied to below suture needle, to on the strap on main cloth, to make little width little compared with spacing make after spacing forms the stitching being more than or equal to 2 pins with common, on main cloth, make strap with above-mentioned common spacing of making.

In addition, the movement of main cloth is undertaken by X-Y feed arrangement, that is, this X-Y feed arrangement makes the planar movement of main cloth press section along level of the main cloth of support.

In addition, if when making spacing with little width and carrying out the stitching being more than or equal to 2 pins, at every turn to make the Length Quantity of spacing corresponding (such as with being at least more than or equal to little width, preferably be more than or equal to little width make in scope that spacing ~ little width makes 2 times of spacing carry), the strap amount of feeding is extracted out along making spacing direction of feed, then makes strap exactly when strap is made.

In addition, when making the strap of linearity on the main cloth of shoes, because (X-direction) forms stitching along its length, so make strap direction of feed (strap feed path) the i.e. X-direction formation of spacing direction of feed along strap feedway 3.

In addition, method of making strap on the main cloth of shoes as noted above, can be applied in strap apparatus for sewing, and this strap apparatus for sewing is the device making strap on the main cloth of shoes, has: workbench, and it is for arranging main cloth; X-Y feed arrangement, it makes the main cloth pressing of the main cloth of support along a planar movement of level; Strap feedway, strap supplies by it on main cloth; And Sewing machines, it is based on tailoring pattern, on main cloth, make strap.In addition, can also be applied in the strap apparatus for sewing with the middle presser feet that suture needle runs through.

Then, carry main cloth LI(or RO with common spacing of making), and strap Tm is made.

As noted above, when making beginning, suture needle 22 is run through, to make spacing with the common little width making about 1mm little compared with spacing, at main cloth LI(or RO) on strap Tm on formed when being more than or equal to the stitching of 2 pins, as shown in figure 24, be equivalent to the mode of the height of main fabric thickness amount to make middle presser feet 23 drop to, middle presser feet 23 is declined, to main cloth LI(or RO) upper pressing strap Tm.Thus, at main cloth LI(or RO) on reliably keep strap Tm.

Then, with common make spacing make strap Tm time, make the height of middle presser feet 23 get back to common height, that is, with the height that main fabric thickness+strap amount of thickness is suitable.

Be placed on the strap Tm of the rectangular strap T(such as bandpass on strap stand 4), because length exists restriction, so make end overlapping with the top of other straps T, connect use by bonding grade.Because this lap is not suitable for making, so usually must excise before making.In the present embodiment, strap seam (strap seam) TG is pasted with the golden zone of reflections.

As shown in figure 25, strap seam sensor 303 is arranged on the upper surface of moveable block 33 via bracket 304, utilizes photoelectric tube to arrange side at strap and detects strap 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 photoelectric tube to send side at strap and detects strap T.

If strap seam TG arrives the strap feed path on strap feedway 3, then as shown in figure 25, above-mentioned strap seam sensor 303 detects the light that the gold ribbon by strap seam TG reflects.

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

That is, strap seam sensor 303 is relative to 2 conveying rollers 381,382, is configured in the transport direction upstream side of rectangular strap, detects the seam of strap.

Strap seam TG after cut-out is sent by front conveying roller 381, as shown in figure 26, detects by utilizing the sending of cloth belt sensor 305 pairs of straps of photoelectric tube.

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

When being removed by strap seam TG, as shown in figure 27, the strap seam TG after operating personnel takes out with finger the cut-out that is sent and being removed.

Here, the front end loading the moveable block 33 of strap T is the surface being undertaken by electroplating processes reflecting.

Strap seam TG after cut-out produces this three state of Figure 38 (a) ~ Figure 38 (c) along with the difference of its off-position (size).

Figure 38 (a) is the situation that strap seam TG is just in time positioned at below cloth belt sensor 305, now, if operating personnel removes strap seam TG, then the detection of cloth belt sensor 305 switches to, connect (gold ribbon) → disconnect (strap) → connect on (without strap=moveable block 33 surface).

Figure 38 (b) is the situation that cloth belt sensor 305 is positioned at strap seam TG rear, and now, if operating personnel removes strap seam TG, then the detection of cloth belt sensor 305 switches to, and disconnects (strap) → connects on (without strap=moveable block 33 surface).

Figure 38 (c) is the situation that cloth belt sensor 305 is positioned at strap seam TG front, now, if operating personnel removes strap seam TG, then the detection of cloth belt sensor 305 switches to, and disconnects (strap) → connects (gold ribbon) → disconnect (strap) → connect on (without strap=moveable block 33 surface).

In arbitrary situation, if remove strap seam TG, then cloth belt sensor 305 all produces the switching of disconnection → connection.

In addition, after utilizing strap seam sensor 303 to check out to be provided with material (strap) this situation (step S18), the display of " without the material " in this display unit 6 is cancelled.

Check in the flow chart of (step S18) at the AB sensor shown in Figure 32, to whether only left and right main cloth sensor 17 in 1 connection judge (step S1801), when only left and right main cloth sensor 17 in 1 connect (step S1801, be), obtain the state (step S1802) of the main cloth sensor 17 of left and right.That is, obtain left and right which connect this information.

Namely, in step S1802, as shown in figure 37, if the main cloth sensor 17a in left side connects, on auxiliary table 1, be then provided with left-external side main cloth LO or the main cloth RI of Right Inboard, in addition, if the main cloth sensor 17b on right side connects, then on auxiliary table 1, left inside side main cloth LI or the main cloth RO in right outside side is provided with.

Then, after the process of step S1802, as normal (step S1803), end process.

In addition, in step S1801,1 in the main cloth sensor 17 not being only left and right, when connecting (step S1801, no), as exception (step S1804), shows " wait workpiece setting ", and to end process in display unit 6.

In addition, material (main cloth) is being set, and after only making 1 interior connection of the main cloth sensor 17 of left and right, is cancelling the display of " the wait workpiece setting " in this display unit 6.

In Figure 29, check after (step S18) continue AB sensor, AB sensor is checked whether and normally judges (step S19), (step S19 in the normal situation of AB sensor inspection, be), carry out the position computing (step S20) of IO sensor (main cloth sensor 18), (the step S19 when AB sensor inspection exception, no), again return the process of step S7.

In the flow chart of the IO sensing station computing (step S20) shown in Figure 33, main cloth sensor 17(17a, 17b according to about shoe size) state, obtain the pattern number for the inspection position movement of any one in main cloth sensor 18 to the left and right or coordinate (obtaining the positional information of any one in the main cloth sensor 18 of left and right) (step S2001), end process.

Namely, if the main cloth sensor 17a in left side connects, then the main cloth sensor 18a in left side is selected as IO sensor, and obtain it and check position, if the main cloth sensor 17b on right side connects, then the main cloth sensor 18b on right side is selected as IO sensor, and obtain its inspection position.As shown in figure 37, in the present embodiment, configured symmetrically by the main cloth sensor 17,18 of left and right, the inspection position of left and right main cloth sensor 18 separately becomes the distance of longitudinal direction D.

In Figure 29, carry out IO sensing station computing (step S20), then presser feet 12 is made to decline (step S21), reference pins 16 is made to decline (step S22), make together with lower plate 11 and upper presser feet 12 and folder main cloth between which, any one main cloth sensor 18(18a, 18b to the left and right) inspection position move (step S23), and carry out the inspection (step S24) of main cloth sensor 18 of left and right.

Check in the flow chart of (step S24) at the IO sensor shown in Figure 34, whether to, the main cloth sensor 18 of left and right is all connected and is judged (step S2401), if not all connecting (step S2401, no), then utilize and check at AB sensor the some main cloth sensors 18 in left and right obtained in (inspection of main cloth sensor 17), carry out IO detection (step S2402).

Namely, in step S2402, check that the main cloth sensor 17a in left side in the step S1802 of (step S18) connects at the AB sensor of Figure 32, and when being provided with left-external side main cloth LO or the main cloth RI of Right Inboard on auxiliary table 1, when the main cloth sensor 18a in left side disconnects, the main cloth LO of left-external side of the height below ankle lower (width is narrower) is arranged on auxiliary table 1, in addition, connect at the main cloth sensor 17a in left side, when the main cloth sensor 18a in left side connects, the main cloth RI of Right Inboard of the height below ankle higher (wider width) is arranged on auxiliary table 1.

In addition, in step S2402, check that the main cloth sensor 17b on right side in the step S1802 of assisting workflows (step S18) connects at the AB sensor of Figure 32, and when auxiliary table 1 is provided with left inside side main cloth LI or the main cloth RO in right outside side, when the main cloth sensor 18b on right side disconnects, the main cloth RO in right outside side of (width is narrower) 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, according to the state of 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 normal situation of IO sensor inspection, be), carry out making (step S26) based on the tailoring pattern selected.

Making in the flow chart of (step S26) shown in Figure 35, till next " strap supply order " or " sewing finishing order ", usually make (step S2601), to being whether that strap supply instruction judges (step S2602), (the step S2602 when strap supply instruction, be), strap seam sensor (strap connecting sensor) 303 being checked (step S2603), judging (step S2604) whether there is strap seam (cloth belt lacing) TG.

In addition, in the tailoring pattern selected in S2403, enrolled strap supply order, sewing finishing order, strap have supplied instruction, the finish command etc. between initiation command, correction zone between correction zone.

In addition, as shown in Figure 40 (a), between correction zone, initiation command enrolls for (g-1) pin, and between correction zone, the finish command enrolls for (h) pin.

Then, in step S2602, if do not have strap to supply instruction (step S2602, no), then to whether being that between correction zone, initiation command judges (step S2630).If initiation command (step S2630, yes) between correction zone, then to additional width corrected value in the amount of movement of stitch data, next pin is made (step S2631).Then S2601 is returned.

In addition, in S2630, if not initiation command (step S2630, no) between correction zone, then to whether being that between correction zone, the finish command judges (step S2632).If the finish command (step S2632, yes) between correction zone, then from the amount of movement of stitch data, deduct width calibration value, next pin is made (step S2633).Then S2601 is returned.

In addition, if be the finish command between correction zone (step S2632, no) in S2632, then end process.

With reference to Figure 40 (a) and Figure 40 (b), step S2631 and step S2633 is described in detail.

The tailoring pattern that Figure 40 (a) is the width calibration value of strap when being 0, Figure 40 (b) operates movable strap guide portion 35 operating personnel, tailoring pattern when cloth bandwidth is increased.They are all by needle falling point e → f → (g-1) → g → h → (h+1) → i.If the spacing between each needle falling point is set to 2mm, then the interval between (g-1) and g, between h and (h+1), be spaced apart 2mm.

Such as, if make cloth bandwidth increase 0.5mm, then at needle falling point (g-1) place of the last pin of needle falling point g at Y direction front side, only make the composition additional width corrected value 0.5mm of Y direction, determine new needle falling point g coordinate (old g coordinate (x, y) → new g coordinate (x, y+0.5)).This means, if initiation command between correction zone, then in the amount of movement of stitch data, add and subtract width calibration value and next pin is made.

In addition, if make cloth bandwidth increase 0.5mm at Y direction front side, then at next needle falling point (h+1) place of needle falling point h, deduct width calibration value 0.5mm, the spacing spacing of h and (h+1) becomes 1.5mm.This means, if the finish command between correction zone, then in the amount of movement of stitch data, add and subtract width calibration value and next pin is made.

Its result, to utilize between this correction zone the finish command between initiation command and correction zone, carry out interval by multiple needle falling points (g to h) of control unit (control cabinet 5) to movable strap guide portion side to specify, corresponding with the amount of movement of movable strap guide portion, multiple needle falling points after having carried out interval appointment are moved in parallel, generates tailoring pattern.

In step S2604, (step S2604 when strap seam (cloth belt lacing) TG, no), abutment joint 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 the strap Length Quantity conveying strap T(step S2608 of the regulation determined in the step S2403 of (step S24) at the IO sensor of Figure 34).

Then, cutter (cutting knife 301) is declined (step S2609), strap T is cut off with specific length, makes front conveying roller 381 decline (step S2610).

Then, in order to make main cloth and suture knotting, and on main cloth, a few pin is only made (such as, be more than or equal to 3 pins) (step S2611), then, before utilizing, conveying roller 381 carries strap T, and strap T is abutted (step S2612) with the knotting part of main cloth and suture.The strap of conveying is transported to below suture needle, is to carry out the position made from main cloth.The strap T of this position is set to strap and makes beginning precalculated position.

As noted above, making under original state, cutter (cutting knife 301) is declined, and front conveying roller 381 is declined, operating personnel supplies the strap T of specific length.

Then, in order to make strap and main cloth tie a knot, and strap T being extracted out, simultaneously making spacing (about 1mm, such as, 0.7mm ~ 1.3mm) with little width and making a few pin (step S2613).

Then, after making, conveying roller 382 declines after (step S2615) and continues to make.Strap T and main cloth are combined by suture, by utilizing feeding (upper presser feet 12, lower plate 11) to make main cloth move, thus the amount constantly needed for pull-out stitching spacing.Then, the process of step S2601 is again returned.

In addition, in step S2604, (step S2604 when there is strap seam TG, be), splice marks (joint marker) is set to connection (step S2616), and it is fixing for the length till seam being set to C(from the length of strap seam sensor 303 to cutting knife 301) (step S2617).

Then, length C > cloth strip length to whether till strap seam TG judges (step S2618), if not length C > cloth strip length (the step S2618 till strap 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 strap comprising strap seam TG is discharged (step S2620).

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

In addition, whether the strap after the discharge of step S2621 is removed, and the switching state according to the detection of cloth belt sensor 305 differentiates.As shown in Figure 38 (a) ~ Figure 38 (c), in arbitrary situation, if strap is removed, then the detection of cloth belt sensor 305 becomes the state of " disconnect → connect ", by detecting this switching state, thus can be judged as that the strap 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 length C > cloth strip length (necessary cloth strip length) (the step S2618 till strap seam TG, be), then by the length till strap seam TG, be set to the length-Bu strip length (step S2625) till strap seam TG, again return the process of step 2606.

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

In Figure 29, after making (step S26), make presser feet 12 increase (step S27), carry out sewing object and reclaim the process (step S28) waited for.

In Figure 29, strap feedway 3 is moved (step S28) to workpiece setting position, carries out pending (step S29) such as sewing object recovery.

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.

Figure 36 is that sewing object reclaims the flow chart waiting for (step S28), according to the state of AB sensor, namely, the state of the main cloth sensor 17 of left and right, obtain the main cloth sensor 17(step S2801 after connection), and whether the main cloth sensor 17 after connecting is become to be off and judged (step S2802).When main cloth sensor 17 one-tenth is off (step S2802, yes), reference pins is made to rise (S2803).Then, end process.Then, the process of step S6 is again returned.
