The motion track of cloth conveying teeth 33 is described with reference to Fig. 5～Figure 11.State when Fig. 5, Fig. 7, Fig. 8, Figure 10 represent to observe cloth conveying teeth 33 and needle plate 15 from left side.Main shaft 14(is with reference to Fig. 1) and upper and lower conveying axis 27(with reference to Fig. 3) under synchronous state, rotate keeping, thereby make cloth pushing table 34(with reference to Fig. 3) move up and down.At shank 7(with reference to Fig. 2) up and down once during in, cloth conveying teeth 33(is with reference to Fig. 3) up and down once.The output shaft 24 of work feed motor 23 often turns to position, the other end from an end position of slewing area, and the horizontal reciprocating swing of cloth pushing table 34 once.Work feed motor 23 synchronously drives with main motor 30.As the curve 301(dotted line of Fig. 6) as shown in, the anglec of rotation of the output shaft 24 of work feed motor 23 (hereinafter referred to as work feed shaft angle) correspondingly changes with the anglec of rotation (hereinafter referred to as upper shaft angle) of the output shaft of main motor 30.CPU44 controls main motor 30 and work feed motor 23, makes shaft angle and work feed shaft angle meet the relation of curve 301.Work feed shaft angle changes in the scope of-30 °～30 °.When work feed shaft angle is 0 °, work feed motor 23 is the state shown in Fig. 3.While changing in upper shaft angle is accumulated at the scope of 0 °～720 °, work feed shaft angle is round trip between-30 °～30 °.That is,, when the output shaft of main motor 30 (omitting diagram) revolves while taking two turns, the output shaft 24 of work feed motor 23 comes and goes and rotates (swing) once.Output shaft 24 come and go rotate once during in, cloth conveying teeth 33 is carried cloth twice.When the output shaft of main motor 30 revolves while turning around, eedle 8 is once made.The angle at the two ends of slewing area-30 of output shaft 24 °～30 ° can change pro rata with cloth feed amount.As shown in Figure 5, cloth conveying teeth 33 moves along the elliptoid motion track 205 under side-looking state according to the order of state 203,202,201,204.When the corresponding relation of upper shaft angle and work feed shaft angle is that curve 301(is with reference to Fig. 6) on some 301A, 301B, 301C, 301D each point shown in be related to time, the position of cloth conveying teeth 33 lays respectively at motion track 205(with reference to Fig. 5) on position 301A, 301B, 301C, 301D.When CPU44 controls corresponding relation that main motor 30 and work feed motor 23 make upper shaft angle and work feed shaft angle and is changed to a some 301B from a 301A, cloth conveying teeth 33 moves towards the place ahead at the downside of needle plate 15.Cloth conveying teeth 33 for example,, owing to being positioned at the downside (state 201,204,203) of needle plate 15, does not therefore contact with cloth.Therefore, cloth conveying teeth 33 does not have work feed.When CPU44 controls corresponding relation that main motor 30 and work feed motor 23 make upper shaft angle and the work feed shaft angle point 301B from curve 301 and is changed to a some 301C, move towards the rear at the upside of needle plate 15 on the top of cloth conveying teeth 33.The top of cloth conveying teeth 33 for example,, owing to being positioned at the upside (state 202) of needle plate 15, therefore contacts with the cloth on needle plate 15.Therefore, cloth conveying teeth 33 work feed rearward.Equally, when CPU44 controls corresponding relation that main motor 30 and work feed motor 23 make upper shaft angle and work feed shaft angle and is changed to a some 301D from a 301C, cloth conveying teeth 33 moves towards the place ahead at the downside of needle plate 15.When CPU44 controls corresponding relation that main motor 30 and work feed motor 23 make upper shaft angle and work feed shaft angle and is changed to a some 301A from a 301D, move towards the rear at the upside of needle plate 15 on the top of cloth conveying teeth 33.Therefore, cloth conveying teeth 33 work feed rearward.Eedle 8 cloth conveying teeth 33 be arranged in needle plate 15 below during in thrust cloth, on cloth, form stitch.
Operator changes cloth conveying teeth 33, needle plate 15, eedle 8 according to the kind (thickness, material etc.) of cloth to be made sometimes.Specifically, when making thicker cloth, compare when making thinner cloth, operator will use the cloth conveying teeth 33 that concavo-convex height is larger.Operator, when making thinner cloth, uses cloth conveying teeth 331(that short transverse size is less with reference to Fig. 5).Operator, when making thicker cloth, uses the larger-size cloth conveying teeth 332(of short transverse with reference to Fig. 7, Fig. 8).When making thicker cloth, operator can increase presser feet 17(conventionally with reference to Fig. 2) by the pressure of compress.Operator uses the different needle plate 15 of thickness (hereinafter referred to as thickness of slab) of plate according to pressure.Operator, when making thinner cloth, uses needle plate 151(that thickness of slab is less with reference to Fig. 5).Operator, when making thicker cloth, uses needle plate 152(that thickness of slab is larger with reference to Fig. 7, Fig. 8).
Fig. 7 represents cloth conveying teeth 332 to be installed on cloth pushing table 34(with reference to Fig. 3) and situation when needle plate 152 is installed.Compare cloth conveying teeth 332 concavo-convex larger in short transverse (above-below direction) with cloth conveying teeth 331.The thickness of slab of needle plate 152 is greater than the thickness of slab of needle plate 151.When in state 202, to compare with cloth conveying teeth 331, the part that cloth conveying teeth 332 is projected into top from work feed perforation 192 is more.Therefore, when cloth conveying teeth 332 moves along the motion track identical with Fig. 5 205, cloth conveying teeth 332 likely in state 201,203 o'clock above work feed perforation 192 is projected into.Moving direction in cloth conveying teeth 332 its horizontal directions is to change in the front and back of state 201,203.When cloth conveying teeth 332 is before its moving direction is changed to rear from the place ahead just above work feed perforation 192 is projected into time, cloth conveying teeth 332 can be from rear work feed (hereinafter referred to as anti-work feed) forwards.When there is anti-work feed, likely can make stitch misplace and cause sewing quality variation.CPU44 drives main motor 30 and work feed motor 23 that cloth conveying teeth 332 is moved along the motion track 210 of Fig. 8.As the curve 302(solid line of Fig. 6) as shown in, work feed shaft angle between a 302L and some 302B, between some 302C and some 302E, between some 302F and some 302H, put 302I and put between 302K constant.In this period, output shaft 24 does not rotate.When the corresponding relation of upper shaft angle and work feed shaft angle is being related to shown in the some 302A～302L each point on curve 302, the position of cloth conveying teeth 332 lays respectively at motion track 210(with reference to Fig. 8) on 302A～position, position 302L.When CPU44 controls corresponding relation that main motor 30 and work feed motor 23 make upper shaft angle and work feed shaft angle and is changed to a some 302B from a 302A, cloth conveying teeth 332 moves downwards at the downside of needle plate 15.Because CPU44 does not make the output shaft 24 of work feed motor 23, do not rotate, therefore, cloth conveying teeth 332 does not move along fore-and-aft direction.When CPU44 controls corresponding relation that main motor 30 and work feed motor 23 make upper shaft angle and work feed shaft angle and is changed to a some 302C from a 302B, cloth conveying teeth 332 moves towards the place ahead at the downside of needle plate 15.Cloth conveying teeth 332, owing to being positioned at the downside of needle plate 15, does not therefore contact with cloth.Therefore, cloth conveying teeth 332 does not have work feed.When CPU44 controls main motor 30 and work feed motor 23 corresponding relation of upper shaft angle and work feed shaft angle is changed according to the order of a 302C, some 302D, some 302E, above the top of cloth conveying teeth 332 moves to from needle plate 15 belows.Because CPU44 does not make the output shaft 24 of work feed motor 23, do not rotate, so cloth conveying teeth 332 does not move along fore-and-aft direction.When CPU44 controls corresponding relation that main motor 30 and work feed motor 23 make upper shaft angle and work feed shaft angle and is changed to a some 302F from a 302E, move towards the rear at the upside of needle plate 15 on the top of cloth conveying teeth 332.Because cloth conveying teeth 332 is positioned at the upside of needle plate 15, so cloth conveying teeth 332 contacts with the cloth on needle plate 15.Therefore, cloth conveying teeth 332 work feed rearward.When CPU44 controls corresponding relation that main motor 30 and work feed motor 23 make upper shaft angle and work feed shaft angle and is changed to a some 302G from a 302F, cloth conveying teeth 33 moves downwards.Because CPU44 does not make the output shaft 24 of work feed motor 23, do not rotate, so cloth conveying teeth 33 does not move along fore-and-aft direction.CPU44 control corresponding relation that main motor 30 and work feed motor 23 make shaft angle and work feed shaft angle according to a 302G, 302H, 302I, 302J, 302K, 302L, 302A(with reference to Fig. 6) order variation.When cloth conveying teeth 33 according to curve 301(with reference to Fig. 6) shown in upper shaft angle and the corresponding relation of work feed shaft angle while moving, cloth conveying teeth 33 starts rearward action when laying respectively at position 301B, 301D, starts action forwards when laying respectively at position 301A, 301C.When cloth conveying teeth 33 according to curve 302(with reference to Fig. 6) shown in upper shaft angle and the corresponding relation of work feed shaft angle while moving, cloth conveying teeth 33 starts rearward action when laying respectively at position 302E, 302K, starts action forwards when laying respectively at position 302B, 302H.Upper shaft angle (putting the upper shaft angle at 301B, 301D, 301A, 301C place) when upper shaft angle when cloth conveying teeth 33 lays respectively at position 302E, 302K, 302B, 302H (the upper shaft angle at some 302E, 302K, 302B, 302H place) is greater than cloth conveying teeth 33 and lays respectively at position 301B, 301D, 301A, 301C.On curve 302, cloth conveying teeth 33 starts rearward or the time of the action in the place ahead is later than cloth conveying teeth 33 on curve 301 and starts rearward or the time of the action in the place ahead.Below, cloth conveying teeth 33 is started rearward or the time of the action in the place ahead is called the time started.When cloth conveying teeth 33 moves according to the corresponding relation of the upper shaft angle shown in curve 301 and work feed shaft angle, cloth conveying teeth 33 is laying respectively at position 301A, 301C(with reference to Fig. 5) time finish rearward action, when laying respectively at position 301B, 301D, finish action forwards.When cloth conveying teeth 33 moves according to the corresponding relation of the upper shaft angle shown in curve 302 and work feed shaft angle, cloth conveying teeth 33 is laying respectively at position 302F, 302L(with reference to Fig. 8) time finish rearward action, when laying respectively at position 302C, 302I, finish action forwards.Upper shaft angle (putting the upper shaft angle at 301A, 301C, 301B, 301D place) when upper shaft angle when cloth conveying teeth 33 lays respectively at position 302F, 302L, 302C, 302I (the upper shaft angle at some 302F, 302L, 302C, 302I place) is less than cloth conveying teeth 33 and lays respectively at position 301A, 301C, 301B, 301D.On curve 302, cloth conveying teeth 33 finishes rearward or the time of the action in the place ahead finishes rearward or the time of the action in the place ahead early than cloth conveying teeth on curve 301 33.Below, cloth conveying teeth 33 is finished rearward or the time of the action in the place ahead is called the end time.With regard to the rotary speed of the output shaft of main motor 30, the rotary speed when rotary speed of output shaft during according to the corresponding relation rotation of the upper shaft angle shown in curve 301 and work feed shaft angle rotated with the corresponding relation of work feed shaft angle according to the upper shaft angle shown in curve 302 with output shaft equates.Therefore the time that, cloth conveying teeth 33 moves to state 203 from state 201 equated with the time that cloth conveying teeth 33 moves to state 208 from state 206.The time started of curve 302 is later than the time started of curve 301.The end time of curve 302 is early than the end time of curve 301.That is the traveling time of the cloth conveying teeth 33, driving according to curve 302 is shorter than the traveling time of the cloth conveying teeth 33 driving according to curve 301.Therefore, with regard to the translational speed of cloth conveying teeth 33, translational speed when translational speed when cloth conveying teeth 33 moves according to the corresponding relation of the upper shaft angle shown in curve 302 and work feed shaft angle moves according to the corresponding relation of the upper shaft angle shown in curve 301 and work feed shaft angle faster than cloth conveying teeth 33.That is, cloth conveying teeth 332 just arrives the end time before above being projected into from work feed perforation 192, after above work feed perforation 192 is projected into, just arrives the time started.Therefore, cloth conveying teeth 332 can be before moving direction is changed to rear from the place ahead above work feed perforation 192 be projected into.Therefore, Sewing machines 1 can suppress the generation of anti-work feed.
As shown in Figure 9, operator, when making thicker cloth, uses the eedle 8 using when the making thinner cloth thick longer eedle 81 of comparing sometimes.Eedle 81 is along with the driving of main motor 30 is moved up and down.Eedle 81 is due to thicker and long than eedle 8, therefore, from above towards below while declining, can earlier thrust in cloth 100 than eedle 8.If cloth conveying teeth 33 with motion track 205(with reference to Fig. 5) work feed 100, eedle 81 can just thrust in cloth 100 before the end time, likely can cause sewing quality variation.Eedle 81 likely can thrust under the state in cloth 100 and move and bend along fore-and-aft direction at eedle 81 because of cloth 100.When eedle 81 is crooked, the lower end of eedle 81 likely can contact with needle plate 15 and cause eedle 81 to be fractureed.Sewing machines 1 when using eedle 81, make cloth conveying teeth 33 along motion track 210(with reference to Fig. 8) mobilely carry out work feed 100.End time when cloth conveying teeth 33 moves along motion track 210 early than cloth conveying teeth 33 along motion track 205(with reference to Fig. 5) end time when mobile.Therefore, Sewing machines 1 can prevent that eedle 8 from just thrusting the situation in cloth 100 at cloth 100 before fore-and-aft direction mobile end, thereby can prevent sewing quality variation.Sewing machines 1 can prevent that eedle 8 from bending, fractureing.Sewing machines 1, when making thicker cloth, preferably suppresses the rising of sewing speed so that operator can easily adjust the position of cloth.When operator makes thicker cloth, CPU44 limits sewing speed by the rotary speed of main motor 30 is arranged to the upper limit.Therefore, can improve the convenience that operator makes operation.When making thinner cloth, CPU44 does not arrange the upper limit to the rotary speed of main motor 30.Therefore, operator can carry out at short notice and make operation.Motion track 205(is with reference to Fig. 5), 210(is with reference to Fig. 8) be the example of the motion track of cloth conveying teeth 33.CPU44 also can control main motor 30 and work feed motor 23 makes cloth conveying teeth 33 move along other motion tracks.For example CPU44 can control main motor 30 and work feed motor 23 makes cloth conveying teeth 33 move along the motion track 215 of Figure 10.When cloth conveying teeth 33 moves along motion track 215, the curve 303(chain-dotted line that the corresponding relation between upper shaft angle and work feed shaft angle is Figure 11) relation shown in the point on.Cloth conveying teeth 332 moves along motion track 215 according to the order of state 213,212,211,214.
