The 100A of bevel tool mechanism, 100B all are positioned at the below of sewing machine table 11, and the large presser feet 21 that is formed by large presser feet feed mechanism 20,21 pass through on the path, be configured to than the more close cloth direction of feed of central cutter 51 front side, by being pierced through filler rod cloth B and the main cloth M that is sent here by large presser foot device 20 from the below by the pair of horns cutting knife, thereby form the roughly joint-cutting of V word shape on the position at the two ends of the joint-cutting S of linearity.
Each bevel tool 100A of mechanism, 100B are set up in parallel along cloth direction of feed F, and the bevel tool 100A of mechanism is configured in the rear of the bevel tool 100B of mechanism.That is, the bevel tool 100A of mechanism can form in the rear end side of straight line joint-cutting S a pair of oblique joint-cutting, and another bevel tool 100B of mechanism can form in the front ends side of straight line joint-cutting S a pair of oblique joint-cutting.And only the bevel tool 100B of mechanism range site travel motor 90 (with reference to Figure 10), can install with respect to sewing machine table 11 along cloth direction of feed F running fix ground.Below, in the situation that two bevel tool mechanisms are described respectively, sometimes the bevel tool 100A of mechanism is called " fixation side ", the bevel tool 100B of mechanism is called " mobile side ".In addition, can be also the bevel tool 100A of mechanism, 100B the two all move on the cloth direction of feed.
In addition, the 100A of bevel tool mechanism and the bevel tool 100B of mechanism, form the roughly the same structure of Mirror Symmetry as benchmark owing to adopting mutually take Y-Z plane, so only cutting on the cross cutter mechanism 100B is elaborated, each structure to the bevel tool 100A of mechanism that becomes Mirror Symmetry structure, mark identical label, description thereof is omitted.
The 100B of bevel tool mechanism has: four bevel tools 101,102,103,104; Unit main body 105, its a pair of axis of guide 14 by the pole shape of the lower face side that is disposed at workbench 11 supports; Transposition section 106, it is block tectosome, in the recess 105a on the rear side surface that is formed at unit main body 105, can be supported movably along Y direction, keep simultaneously each bevel tool 101～104; As the travel mechanism of transposition section 120 of bevel tool selection mechanism, it carries out running fix along Y direction to transposition section 106; And reciprocating mechanism 130, it utilizes the co-operating with travel mechanism of transposition section 120, selects bevel tool and it is moved up and down.
Unit main body 105 is the frame shape, and is supported with the state that inserts a pair of axis of guide 14 in an end of Y direction.In addition, form recess 105a on a side of the rear side that becomes unit main body 105, in the inboard of this recess 105a configuration transposition section 106.And, the support that is fixed of the unit main body 105 of the 100A of bevel tool mechanism, and the unit main body 105 of the bevel tool 100B of mechanism via not shown belt feed mechanism or ball screw framework, can be located on the optional position of X-direction by the driving of cell moving motor 90.In addition, also can use linear motor as cell moving motor 90.
In transposition section 106, fixed installation from the side of its Y direction along Y direction two of extended up and down support bar, be arranged at inserting in the hole of unit main body 105 sides by these support bars are inserted, thus realize transposition section 106 with respect to unit main body 105 along Y direction supported state movably.
Upper surface in transposition section 106 arranges four bevel tool erecting beds 107,108,109,110, and each erecting bed 107～110 keeps respectively bevel tool 101～104.These erecting beds 107～110, by unclamping not shown fastening bolt, can carry out the angular adjustment around Z axis (with reference to Fig. 9 (A)) of each bevel tool 101～104, and can by manual operations regulate point of a knife towards angle of inclination (with reference to Fig. 9 (B)).Each bevel tool 101～104 determines by the angular adjustment around Z axis the angle of inclination that oblique joint-cutting forms with respect to straight line joint-cutting S, by regulate point of a knife towards the angle of inclination, the shearing length of the oblique joint-cutting of decision.
The adjustment example of each bevel tool 101～104 of observing from the top here, is described based on Fig. 8 (B).Two bevel tools 101,102 on right side are used to form the oblique joint-cutting that is formed at the right side with respect to straight line joint-cutting S, all tilt towards the place ahead and to the direction of keeping right, but bevel tool 102 so that the elongated mode of the shearing length of oblique joint-cutting tilt.In addition, being adjusted into width h1 and the h2 of oblique joint-cutting on Y direction that is formed by each bevel tool 101,102 equates.
Two bevel tools 103,104 in left side are used to form the oblique joint-cutting that is formed at the left side with respect to straight line joint-cutting S, and it all tilts towards the place ahead and to the direction that keeps left, but bevel tool 104 so that the elongated mode of the shearing length of oblique joint-cutting tilt.In addition, with each bevel tool 101,102 situation in the same manner, be adjusted into width h1 and the h2 of oblique joint-cutting on Y direction that is formed by each bevel tool 103,104 and equate.That is, bevel tool 101,103 is equivalent to " chopped cutter ", and bevel tool 102,104 is equivalent to " long cutting knife ".
In addition, each erecting bed 107～110 has sliding axle along Z-direction (omitting diagram) at its downside, utilizes the slip of this axle, can be up or down supported by transposition section 106.And in the bottom of this each sliding axle, forming the engaging protrusion of forwards protruding is shears 107a～110a.These shearss 107a～110a more forwards protrudes than the front surface of transposition section 106, and reciprocating mechanism 130 described later moves up and down each bevel tool 101～104 via these shearss 107a～110a.
Travel mechanism of transposition section 120 has: as the transposition section motor 121 of positioning motor, it is fixedly mounted on the top of unit main body 105; Thread spindle 122, it is by transposition section motor 121 rotary actuations; And moving body 123, it is connected with this thread spindle 122 via ball-screw.
Thread spindle 122 rotatably is supported on the upper surface of unit main body 105 with the state along Y direction, and the one end links via the output shaft of shaft coupling and transposition section motor 121.
Moving body 123 is kept from the Y direction one extended arm 106b in end by transposition section 106.Thus, if thread spindle 122 utilizes transposition section motor 121 to be driven in rotation, moving body 123 bears locomotivity due to the effect of ball screw framework on the length direction (Y direction) of thread spindle 122, and the Y direction of carrying out transposition section 106 moves.
The Y direction of the transposition section 106 that is undertaken by travel mechanism of described transposition section 120 moves, use when the pair of horns cutting knife of selecting to be moved up and down by reciprocating mechanism 130 from each bevel tool 101～104 described later, simultaneously use to the forming the position of position on Y direction and regulate of the oblique joint-cutting that formed by the bevel tool of selecting the time.
Reciprocating mechanism 130 has: the 1st cylinder 131, and it rises bevel tool, thereby forms oblique joint-cutting on the right side of straight line joint-cutting S; The 2nd cylinder 132, it rises bevel tool, thereby forms oblique joint-cutting in the left side of straight line joint-cutting S; As the cylinder bracket 133,134 of engaging part, it is arranged on each cylinder 131,132 output shaft, selectively engages with aforementioned shears 107a～110a.
Each cylinder 131,132 is arranged on unit main body 105 in its direction of action mode parallel with Z-direction.
Each cylinder bracket 133,134 is only to make the axial mid portion path of cylinder and the drum type parts that form, makes its center line under the state of Z-direction, is arranged on each cylinder 131,132 output shaft.And, with each cylinder 131,132 and each cylinder bracket 133,134 be disposed on unit main body 105, so that when transposition section 106 moves along Y direction, the leading section of each shears 107a～110a by each cylinder bracket 133,134 by between the position of path.
Namely, if transposition section 106 moves along Y direction, because each shears 107a～110a puts in order by between each cylinder bracket 133,134 minor diameter part by this, so the transposition section motor 121 by controlling travel mechanism of transposition section 120 is so that become between the minor diameter part that the shears of the bevel tool of action object stops at cylinder bracket 133 and 134, thereby the shears of regulation is engaged with cylinder bracket, can utilize the 1st or the 2nd cylinder 131,132 driving, make the bevel tool of regulation carry out lifting action.
In addition, transposition sensor 111 (with reference to the Figure 10) of section that have optical profile type at the lower surface of unit main body 105, it detects transposition section 106 and is in following three positions: the shears 107a of (1) bevel tool 101 is positioned at the position that engage with cylinder bracket 133, and the shears 109a of while bevel tool 103 is positioned at the situation of the position that engages with cylinder bracket 134; (2) the shears 108a of bevel tool 102 is positioned at the situation of the position that engages with cylinder bracket 133; And the shears 110a of (3) bevel tool 104 is positioned at the situation of the position that engages with cylinder bracket 134, utilizes described sensor to detect and carries out the positioning control of transposition section 106.And, the state of above-mentioned (1)～(3) is called the state that each bevel tool 101～104 is positioned at operating position.
In addition, due to each cylinder bracket 133,134 scopes that overlap with each shears 107a～110a, as shown in Fig. 8 (C), has certain width on Y direction, even so that each shears 107a～110a moves in Y direction with respect to each cylinder 133,134 is a certain amount of, also can keep fastening state.And, can in the scope that can keep this fastening state, each bevel tool 101～104 be moved on Y direction, carry out the position adjustments of off-position.
(control system of fillet sewing machine)
In Figure 10, what fillet sewing machine 10 was described comprises action control unit 80 in interior control system.

In addition, action control unit 80 is respectively via driver 45a, 23a, 57a, 90a, 70a, is connected to become machine spindle motor 45, presser foot motor 23, cutting knife motor 57, the cell moving motor 90 of its control object and switches the operating state of cutting knife motor and the electromagnetic valve 70 of the cylinder 65 of driving condition.
In addition, action control unit 80 is via driver, connects to drive respectively make the cylinder that holder 30 moves up and down and make large presser feet 21,21 carry out the electromagnetic valve (omitting diagram) of the cylinder of lifting.In addition, the 1st and the 2nd cylinder 131,132 electromagnetic valve 135,136 and above-mentioned transposition section sensor 111 that in the same manner, via driver 121a, 135a, 136a, input circuit 111a, connect transposition section motor 121, carry out the bevel tool lifting.
In addition, action control unit 80 connects the not shown cutter driving air cylinder driven that is used for driving the cutting knife that carries out the suture cut-out and switches solenoid 43 with electromagnetic valve 89 and aforementioned pin via driver 89a, 43a.
In addition, bevel tool mechanism arranges two, but in Figure 10, about the structure of bevel tool mechanism, only illustrates this internal structure of the bevel tool 100B of mechanism, to another bevel tool 100A of mechanism, omits its internal structure and illustrates.
Action control unit 80 has: CPU81, and it carries out various processing and control; ROM82, its write to the various settings of fillet sewing machine 10 carry out input processing setting input program 82a, carry out the first cutting-off controlling program 82b and the second cutting-off controlling program 82c and the center joint-cutting formation control program 82d of the Sewing machines action control in filler rod; As the RAM83 of working region, it is store various kinds of data in the processing of CPU81; And EEPROM71, it records stitch data and various setting data.
(setting input program)
when carrying out filler rod, input by showing that input block 85 is set in advance: the left and right straight line stitching TL on cloth direction of feed F, the leading section position PFL of TR, PFR and rearward end position PRL, PRR (with reference to Fig. 2), with two straight line stitching TL, the end position XS of straight line joint-cutting S on X-direction that is formed by center joint-cutting 51 that the end of TR is corresponding, to be carried out the selection that the forms setting of angle joint-cutting by the first cutting-off controlling described later or the second cutting-off controlling, in each pin by large presser feet 21, the 21 cloth B that produce, the amount of feeding of M is set, these data are stored in EEPROM71.
Fillet sewing machine 10 has mark lamp (not shown), its become the main cloth M that makes object and filler rod cloth B operation is set the time, the assigned position of irradiation workbench, as one man arrange by the irradiation position of making starting position or end position and described mark lamp with main cloth M and filler rod cloth B, can begin to make from the precalculated position to these clothes.
In above-mentioned fillet sewing machine 10, be arranged on correct assigned position as prerequisite to become the main cloth M and the filler rod cloth B that make object, carry out the action control of cloth feeding.Namely, as long as main cloth M and filler rod cloth B are arranged on assigned position, just can know when with carry out to a certain degree large presser feet 21,21 mobile the time, predefined " leading section position PFL, PFR and rearward end position PRL, the PRR of left and right straight line stitching TL, TR on cloth direction of feed F " whether be positioned at each suture needle 41,41 under the position, thus, to main cloth M and the filler rod cloth B that is sent here by large presser feet 21,21, calculate the control of the timing of making beginning and sewing finishing of each straight line stitching TL, TR.
Therefore, if CPU81 is according to setting input program 82a, from showing leading section position PFL, PFR and rearward end position PRL, the PRR of left and right straight line stitching TL, TR on input block 85 input cloth direction of feed F, carry out its value is stored in processing in EEPROM71.
In addition, CPU81 is according to setting input program 82a, leading section position PFL, PFR and rearward end position PRL, PRR according to left and right straight line stitching TL, TR on cloth direction of feed F, PFL is subtracted PFR and calculates anterior end position deviation CF, PRL is subtracted PRR and calculates rearward end position deviation CR, be stored in EEPROM71.
In addition, if CPU81 determines the anterior end position FE of straight line joint-cutting S and the information of rear end position RE (with reference to Fig. 1, Fig. 2) according to setting input program 82a from showing input block 85 inputs, its value is stored in EEPROM71.Figure 11 means at the make decision key diagram of example of anterior end position FE of straight line joint-cutting S of the situation of carrying out filler rod shown in Figure 2.
as noted above, due to the angular adjustment around Z axis of carrying out each bevel tool 101～104 (with reference to Fig. 9 (A)), with utilize manual operation regulate point of a knife towards angle of inclination (with reference to Fig. 9 (B)), so action control unit 80 is in order to determine and straight line stitching TL, the end position of straight line joint-cutting S on cloth direction of feed (X-direction) that the end position of TR is corresponding, need to adjust each bevel tool 101～104 around the angular adjustment of Z axis and point of a knife towards the angle of inclination, utilize simultaneously the information that the anterior end position FE of straight line joint-cutting S (also record and narrate and be leading section position FE) or rearward end position RE (also record and narrate and be rearward end position RE) are determined in input program 82a input of setting.
for example, the situation of filler rod is carried out in existence with the first cutting-off controlling, namely, oblique joint-cutting (VFL and VFR) for the left and right sides across straight line joint-cutting S shown in Figure 2, utilization is two cutting knifes 101 and 103 of chopped cutter, an end that makes each oblique joint-cutting when making each other shearing length (CLS) equal is consistent with the end of corresponding respectively straight line stitching, form oblique joint-cutting under this configuration, in the case, in fact the operator is forming straight line stitching TL, in the time of TR, for each bevel tool 101, 103, equally adjust around the angular adjustment of Z axis and point of a knife towards angle of inclination (θ 1), when the joint-cutting of the angle of formation expectation, with the length X S of oblique joint-cutting VFR on the cloth direction of feed, input information as the anterior end position FE that determines straight line joint-cutting S.Then, action control unit 80 is according to setting input program 82a, the length X S in EEPROM71 on this cloth direction of feed of storage.Although diagram is omitted, for the rearward end RE of straight line joint-cutting, also in the same manner with the length on the cloth direction of feed of oblique joint-cutting VRL, as the input information of determining rear end end position RE.In the case, EEPROM71 works as memory cell, and it is stored by the length X S of shearing length on the cloth direction of feed that is the bevel tool 101 of chopped cutter or the oblique joint-cutting that bevel tool 103 forms.
and, length X S on this cloth direction of feed for example uses in the following cases, namely, in the situation that carry out as shown in figure 11 carry out filler rod with the first cutting-off controlling, CPU81 is by the joint-cutting formation control program 82d of implementation center, with the definite anterior end position as straight line joint-cutting S of position FE, this position FE, from two straight line stitching TL, in TR relatively the end PFR of an extended side straight line stitching TR begin, non-extension side to straight line stitching TR, position after deflection length X S (shearing length that is formed by chopped cutter is in the length on the cloth direction of feed).
in addition, length X S on this cloth direction of feed for example uses in the following cases, namely, in the situation that carry out as shown in figure 12 carry out filler rod with the second cutting-off controlling, CPU81 is by the joint-cutting formation control program 82d of implementation center, determine that position FE is as the anterior end position of straight line joint-cutting S, this position FE, from two straight line stitching TL, in TR not relatively the end of an extended side straight line stitching TL begin, non-extension side to straight line stitching TL, position after deflection length X S (shearing length that is formed by chopped cutter is in the length on the cloth direction of feed).
In the case, as Figure 11 and shown in Figure 12, make the anterior end position FE of straight line joint-cutting S, in the situation that relatively the end position PFR of extended stitching determines uniquely as benchmark in two straight line stitching TL, the TR, owing to becoming respectively these two different values of XS and XL in the first cutting-off controlling and the second cutting-off controlling, XL changes along with the tilt angle theta 2 of long cutting knife simultaneously, so the operator when determining the end position FE of straight line joint-cutting S, needs very numerous and diverse input operation.
but, carry out above-mentioned center joint-cutting formation control program 82d by CPU81, with can be only based on the length X S of shearing length on the cloth direction of feed of chopped cutter, determine the mode of the anterior end position FE of straight line joint-cutting S, corresponding with selecteed cutting-off controlling program and automatically change the reference position, determine the anterior end position FE of straight line joint-cutting S, so the operator only inputs the length X S of shearing length on the cloth direction of feed that is formed by chopped cutter, just can set the anterior end position FE of straight line joint-cutting S, when switching the first and second cutting-off controllings or when readjusting the tilt angle theta 2 of long cutting knife, can reduce further input and determine the working load of information (XL) etc. of the anterior end position FE of straight line joint-cutting S.
In addition, Figure 11 and Figure 12 are in the situation that determine the key diagram of the anterior end position FE of straight line joint-cutting S, but for the rearward end position RE of straight line joint-cutting S, also can in the same manner, only determine with the length of shearing length on the cloth direction of feed that is formed by corresponding chopped cutter by input.
In addition, " by the first cutting-off controlling carries out or the selection that the second cutting-off controlling carries out is set ", be for which the setting of selecting to carry out the first cutting-off controlling program 82b and the second cutting-off controlling program 82c when forming the angle joint-cutting, undertaken by the operation that shows input block 85 by the operator.
" amount of feeding by large presser feet 21,21 cloth B, M in each pin is set " is so-called cloth feed speed.That is, by controlling large presser feet feed mechanism 20, make with the speed that moves up and down of suture needle and synchronize and move with the regulation amount of feeding in each pin, thereby can make with constant space.In addition, in other straight line joint-cutting S or the formation control of angle joint-cutting, due to so that large presser feet 21 is moved as prerequisite determines action regularly with the regulation amount of feeding, so must preset the amount of movement in each pin.And, when the action control of filler rod, with reference to the amount of movement in each pin that is stored in EEPROM71, according to the elapsed time from the action beginning, judge cloth M, B are positioned at which position (position on the cloth direction of feed), carry out exercises and control.
" the bevel tool 100B of mechanism when the angle joint-cutting forms is with respect to the amount of movement of the bevel tool 100A of mechanism " is the bevel tool 100A of mechanism when forming the angle joint-cutting on the end, front and back of straight line stitching TL, TR and the separating distance between the bevel tool 100B of mechanism.Namely, in the time of in the configuration that cloth M, B is transported to each bevel tool 100A of mechanism, 100B, driver element travel motor 90, make the bevel tool 100A of mechanism and the bevel tool 100B of mechanism become corresponding with the length of straight line stitching TL, TR and state that separate, thus, can form simultaneously the angle joint-cutting on the end, front and back of straight line stitching TL, TR.For example, can be set as the value consistent with the length of straight line joint-cutting S.
(the angle joint-cutting formation control of filler rod: the first cutting-off controlling)
The angle joint-cutting formation control of filler rod is undertaken by the first cutting-off controlling program 82b and the second cutting-off controlling program 82c that are stored in above-mentioned ROM82.That is, by carrying out said procedure 82b, 82c, CPU81 works as the first control module.
The first cutting-off controlling program 82b makes CPU81 carry out the program of the first cutting-off controlling, this first cutting-off controlling for make large presser feet feed mechanism 20 press motor 23 and the bevel tool 100A of mechanism, 100B form angle joint-cutting shown in Figure 2, for oblique joint-cutting VFL, the VFR (or VRL, VRR) across the left and right sides of straight line joint-cutting S, an end that makes each oblique joint-cutting VFL, VFR (or VRL, VRR) when each other shearing length equates is consistent with the end of corresponding straight line stitching TL, TR, formation angle joint-cutting under this configures.
on the other hand, the second cutting-off controlling program 82c is carried out the program of the second cutting-off controlling by CPU81, this second cutting-off controlling is pressed motor 23 and the bevel tool 100A of mechanism for what make large presser feet feed mechanism 20, 100B forms angle joint-cutting shown in Figure 3, for the oblique joint-cutting VFL across the left and right sides of straight line joint-cutting S, VFR (or VRL, VRR), when making mutual shearing length different, make each oblique joint-cutting VFL, VFR (or VRL, VRR) the straight line stitching TL that both ends are corresponding with difference, the end of TR is consistent with the end of straight line joint-cutting S, form the angle joint-cutting under this configuration.
Above-mentioned first and second cutting-off controlling program 82b, 82c which is carried out by being utilized by the operator to select to set as the demonstration input block 85 of selected cell, thereby CPU81 carry out according to selection.Below, describe respectively first and second cutting-off controlling in detail.
In the formation of angle joint-cutting, use the bevel tool 100B of mechanism in the formation of the angle of anterior end joint-cutting, form the middle use bevel tool 100A of mechanism at the angle of rearward end side joint-cutting.Here, describe as an example of the angle joint-cutting that forms the leading section side example.
In the first cutting-off controlling, use the bevel tool 101 and 103 of the bevel tool 100B of mechanism.Namely, CPU81 is after utilizing large presser feet feed mechanism 20 to make the leading section PFR angle of arrival cutter mechanism 100B of straight line stitching TR of cloth M, B, at first form oblique joint-cutting VFR by making bevel tool 101 increase, then, after utilizing the large presser feet feed mechanism 20 supply side position deviation CF of section amounts, make bevel tool 103 increase and form oblique joint-cutting VFL.
In addition, the bevel tool 100B of mechanism range site travel motor 90 is pre-configured on the position of separating with predetermined distance with respect to the bevel tool 100A of mechanism, and each bevel tool 100A of mechanism, 100B carry out cut-out simultaneously.
In the second cutting-off controlling, use the bevel tool 102 and 103 (more lean on the rear if the end position deviation setting is oblique joint-cutting VFR than VFL, use bevel tool 101 and 104) of the bevel tool 100B of mechanism.That is, CPU81 forms oblique joint-cutting VFR, VFL by making bevel tool 102 and 103 increase after utilizing large presser feet feed mechanism 20 to make the leading section PFR angle of arrival cutter mechanism 100B of straight line stitching TR of cloth M, B.That is, oblique joint-cutting VFR and VFL because the end position on the X-direction of straight line joint-cutting S side is consistent, do not form so do not follow feed motion during this period.
In addition, the bevel tool 100B of mechanism range site travel motor 90 is on the position of separating with predetermined distance with respect to the bevel tool 100A of mechanism in advance, and each bevel tool 100A of mechanism, 100B carry out cut-out simultaneously, and this point is identical with the first cutting-off controlling.
(the center joint-cutting formation control of filler rod)
The center joint-cutting formation control of filler rod utilizes the center joint-cutting formation control program 82d that is stored in ROM82 to carry out.That is, CPU81 works as the second control module by the joint-cutting formation control program 82d of implementation center.
Namely, CPU81 is by the joint-cutting formation control program 82d of implementation center, judge to select which in the first cutting-off controlling and the second cutting-off controlling in the joint-cutting formation control of angle after, carry out following control, that is, when selecting the first cutting-off controlling, determine the end position of straight line joint-cutting as benchmark take the end of extended straight line stitching, when selecting the second cutting-off controlling, determine the end position of straight line joint-cutting as benchmark take the end of not extended straight line stitching.
Here, so-called " extending ", a side straight line stitching (being straight line stitching TR in Fig. 2,3) for the leading section side represents relatively forwards to extend represents a side straight line stitching (being straight line stitching TL in Fig. 2,3) that relatively rearward extends for the rearward end side.Here, former end side is that example describes.
As Figure 11, shown in Figure 12, in the situation that the bevel tool 100B of mechanism uses respectively long and short two kind bevel tool and carries out the first cutting-off controlling and the second cutting-off controlling, the prerequisite length X S of shearing length on the cloth direction of feed that to be the shearing length that formed by bevel tool 102 (long cutting knife) form at the length X L on the cloth direction of feed with by bevel tool 103 (chopped cutter) is poor, consistent with end position deviation CF (CF=XL-XS).namely, in the second cutting-off controlling, from the end PFR (with reference to Fig. 2) of extended straight line stitching, position to from non-extension lateral deviation to the length X L of the shearing length that is formed by bevel tool 102 on the cloth direction of feed, end PFL (with reference to Fig. 2) beginning of the straight line stitching that never extends, position to from non-extension lateral deviation to the length X S of the shearing length that is formed by bevel tool 103 on the cloth direction of feed, all consistent with leading section position FE shown in Figure 12, in the situation that corresponding with the second cutting-off controlling and form the straight line joint-cutting, its leading section position FE can determine as benchmark with any in the end of the end of extended straight line stitching and not extended straight line stitching.
If in any situation of the first cutting-off controlling and the second cutting-off controlling, all the end PFR take extended straight line stitching determines the end position of straight line stitching as benchmark, selecting to switch in the situation (the perhaps situation opposite with it) of the second cutting-off controlling from the first cutting-off controlling, needing the distance from the end of straight line stitching to the end position of straight line joint-cutting is reset to length X L (or opposite) from length X S.
But, by the joint-cutting formation control program 82d of implementation center, CPU81 by when the first cutting-off controlling take the end PFR of extended straight line stitching TR as benchmark, when the second cutting-off controlling take the end PFL of not extended straight line stitching TL as benchmark, thereby in any situation, all can based on the length X S of the shearing length that is formed by bevel tool 103 on the cloth direction of feed, determine the end position of straight line joint-cutting.Thus, when switching the first and second cutting-off controllings, can reduce that again the range difference between the end PFL of the end PFR of straight line stitching TR and straight line stitching TL is set as the working load of length X L (or opposite) from length X S.And, the operator need to be corresponding with the setting value of end position deviation CF (or RF), adjust bevel tool 102 (or bevel tool 104) around the angular adjustment of Z axis and point of a knife towards angle of inclination (θ 2), but in the situation that present embodiment, do not need to input the length X L corresponding with the angle of inclination of changing (θ 2) and get final product, further reduce working load.
