In Fig. 5, the screw 24 of setting tool 8 to be pulled down, the installation portion 13 of the annex 10 by Fig. 4 clips under the state at two ends of setting tool 8, and screw 15,16 (Fig. 4) is tightened.Thus, as shown in Figure 6, annex 10 is fixed on the setting tool 8.Below, the method for sewing that uses annex 10 is described.
Fig. 7 A represents two cloth 53 are clipped in state between pressing element 5 and the feeding tooth 52.The height that leaves supporting surface 50 of pressing element 5 is height h1.The state of this figure is that pressing element 5 is descended from the upper end position of height h, begins to be connected to the state of the position maintenance pressing element 5 on the cloth 53 at pressing element 5.
Thereby under the state of Fig. 7 A, pressing element 5 is maintained on the position that does not compress cloth 53.That is, even from the state of Fig. 7 A cloth 53 of dismantling, pressing element 5 is also kept height h1.Below, with reference to Fig. 8, Fig. 9, the process till the state that becomes Fig. 7 A is described.
Fig. 8 is the knee control lift lever 6 under the state of presentation graphs 7A and the front view of annex 10.If the power F that the backing plate 7 with knee control lift lever 6 one is applied is increased, then knee control lift lever 6 is the center with the center 40a of axle 40, rotates to arrow a direction.
Knee control lift lever 6 expression knee control lift levers 6 shown in the dotted line of Fig. 8 rotate to the state of the end.Under this state, the pressing element 5 shown in the dotted line of Fig. 7 A is such, and pressing element 5 rises to the position of height h.Cloth 53 can be placed on the supporting surface 50 under this state.
If the state from the knee control lift lever 6 shown in the dotted line will loosen the power F that backing plate 7 applies, then knee control lift lever 6 moves towards original position to rotating with arrow a opposite direction.The reaction force that should mobile be spring 47 (Fig. 2) brings.Along with this moves, the pressing element of being represented by the dotted line of Fig. 7 A 5 descends to supporting surface 50 sides.
The position of the knee control lift lever 6 shown in the solid line of Fig. 8 is that the height of the pressing element 5 of Fig. 7 A is the position of height h1.The strong F of effect on backing plate 7, knee control lift lever 6 is remained on the position of representing with solid line temporarily.As mentioned above, the height h1 of Fig. 7 A is that pressing element 5 begins to be connected to the position on the cloth 53.
In order to keep knee control lift lever 6 temporarily, situation about need finely tune is arranged so that it is in this position.In the case, Yi Bian for example can on one side the dislocation of cloth 53 front and back be finely tuned.The power F of applying just can use two hands to carry out as long as knee is connected on the backing plate 7 in such fine setting.In addition, use Figure 14 to describe in the back to fine setting being become be easy to method.
In Fig. 8, the central shaft of line 55 expression axles 18.The central shaft of the axle 18 of the initial position of line 54 expression knee control lift levers 6.In the example of this figure, line 54 is the lines with brace table 3 quadratures.Under the state of Fig. 8, axle 18 central shaft is compared the position that is indexed to line 55 from line 54 with the initial position of knee control lift lever 6, and axle 18 has compared angle θ 1 with initial position.Altogether, between the front end of abutting part 19 and plate 22, form gap s.
If remove power F from this state, then in Fig. 7 A, pressing element 5 will further descend from the position of height h1 by the reaction force of spring 47 (Fig. 2), compresses cloth 53.
In the present embodiment, by possessing annex 10,, also shown in Fig. 7 A, can keep pressing element 5 to be in the state of the position of height h1 even power F is removed.For this point, below describe with reference to Fig. 8, Fig. 9.
In Fig. 8, axle 18 is screwed in the hole 21 of support portion 14.Therefore, by making knob 20 rotation, can regulate movable part 12 from the support portion 14 overhang d.In Fig. 8, overhang d is d1.If from this state knob 20 is continued to making overhang d become big direction rotation, then gap s disappears, and the front end of abutting part 19 is connected on the plate 22.
Fig. 9 is the front view that the front end of expression abutting part 19 is connected to the state on the plate 22.14 overhang d is changed to the d2 bigger than the d1 of Fig. 8 to movable part 12 from the support portion, and gap s disappears.In the case, axle 18 is mobile along the central shaft (line 55 of Fig. 8) of axle 18 from the state of Fig. 8, so the angle θ 1 of Fig. 8 is also kept in Fig. 9.
And then because the front end of abutting part 19 is connected on the plate 22, so the leeway that does not have annex 10 to move, even the power F that will be applied on the backing plate 7 removes, axle 18 has also been kept the state of angle θ 1.In the case, also keep the height h1 of Fig. 7 A for pressing element 5, pressing element 5 is also kept the state that does not compress cloth 53.
On the other hand, in Sewing machines in the past, under the situation that begins to make, the reaction force that becomes by spring 47 (Fig. 2) will be raised to the state that cloth 53 is in the position of height h1 towards the pressing element 5 of supporting surface 50 sides.Under this state, pressing element 5 is compressing cloth 53.In the case, the cloth of the downside of supporting surface 50 sides is fed the tooth feeding, but the cloth of the upside of pressing element 5 sides is compressed by pressing element 5.Therefore, while the inclined to one side phenomenon of seam that cloth up and down misplaces and is fed takes place easily.
In the present embodiment, as mentioned above, the gap between pressing element 5 and the cloth 53 can be eliminated and the position of pressing element 5 is remained to pressing element 5 in advance not compressing on the position of cloth 53 or the position that thrust is suppressed enough for a short time.If begin to make under this state, then when making, the cloth of the upside of pressing element 5 sides moves the dislocation of the cloth about also preventing by manual adjustments easily with the cloth one of the downside of supporting surface 50 sides easily.
That is, according to the method for sewing of relevant present embodiment, comparing Yi Bian by pressing element 5 cloth 53 is compressed the method for sewing of making in the past with stronger thrust with one side, is favourable for preventing to stitch partially.
More than, the situation that two cloth are sewed up is illustrated, below the situation that 3 cloth are sewed up is described.Under the state of Fig. 7 A, have after two cloth are sewed up, cloth to be turned back, the situation with 3 cloth are sewed up describes this example.
The state of Fig. 7 A is the state that pressing element 5 does not compress cloth 53 as mentioned above.If making the cloth 53 of the downside of pressing element 5 from this state is 3, then pressing element 5 lifts, and by the reaction force of spring 47 (Fig. 2), pressing element 5 compresses cloth 53.
In order to make pressing element 5 not compress cloth 53, also can illustrate like that as using Fig. 8, Fig. 9, with cloth be under two the situation the adjusting order equally, regulate again movable part 12 from the support portion 14 overhang d.
On the other hand, the Sewing machines 1 about present embodiment is equipped with the annex 30 (Fig. 1) that separates with annex 10.By using this annex 30, the height setting that appends the pressing element 5 under the situation of sutural lamina number becomes easy.
Figure 10 is the stereogram of annex 30.Figure 11 represents the side view of annex 30.Annex 30 possesses hand 31 and is the arm 32 of one.Hand 31 is formed with gap 31a (Figure 11), the small pieces 54 of cloth can be clamped among the 31a of gap.These small pieces 54 are identical with the cloth of making object.
In Figure 11, gripper shoe 32 is fixed on the back side of brace table 3 (Fig. 1) by screw 34.Arm 32 and binding parts 35 are fixing by screw 36, link parts 35 and are rotatably installed on the gripper shoe 33 by bolt 37.Thus, in Figure 10, arm 32 can be middle mind-set arrow k direction rotation with bolt 37.By this rotation, the small pieces 54 that are clipped in the hand 31 can be transported to plate 22 sides.
In addition, Figure 10, annex 30 shown in Figure 11 are examples, as long as can make the small pieces 54 that remain on the hand move to the front position of movable part 12, also can be other mechanisms.
Below, the using method of annex 30 is described.As mentioned above, shown in Fig. 7 A, the height that leaves supporting surface 50 at pressing element 5 is under the state of height h1, and as shown in Figure 9, the angle of inclination of the axle 18 of annex 10 is θ 1.
If be connected to state on the plate 22 from the such abutting part 19 of Fig. 9, make knee control lift lever 6 to the rotation of arrow a direction, then between abutting part 19 and plate 22, form the gap.Under the state that has formed this gap, make arm 32 rotation of the annex 30 of Figure 10, can be transported in the gap of downside of plate 22 being clipped in cloth 54 on the hand 31.
Figure 12 represents to make arm 32 rotations and will be clipped in the figure of state that small pieces 54 in the hand 31 are transported to the position of plate 22.Under the state of this figure, will the power of knee control lift lever 6 rotations be removed, the front end of abutting part 19 is connected on the cloth.
Figure 13 represents near the front view of the annex 10 under the state of Figure 12.Between abutting part 19 and plate 22, clip small pieces 54.Thereby, sandwiching Fig. 9 before with small pieces 54 and compare, annex 10 and knee control lift lever 6 are middle mind-set arrow a direction rotation with the center 40a of axle 40.
That is, the tilt angle theta 1 of Fig. 9 is changed to the angle θ 2 bigger than angle θ 1 in Figure 13.Thereby the height of the pressing element 5 among Fig. 7 A has uprised corresponding to the amount of height of the differential seat angle of angle θ 2 and angle θ 1, has been the amount of thickness of small pieces 54.
Fig. 7 B is the height of expression pressing element 5 is changed to the state of h2 from height h1 a side view.The position of the pressing element 5 of this figure is the position of abutting part 19 when being connected on the small pieces 54 as shown in Figure 13.The height of pressing element 5 is height h1 in Fig. 7 A, with respect to this, in Fig. 7 B, it has been added clearance t and has become height h2.Clearance t is corresponding to the thickness of small pieces 54.
In Figure 13,, in Fig. 7 B, pressing element 5 can be raised to the upper end position of the height h of Fig. 7 B by making knee control lift lever 6 to the position that the dotted line that rotates to the end is rotated, moved to arrow a direction.Under this state, 3 overlapping cloth 53 can be placed on the supporting surface 50.Then, in Figure 13, if the power that will apply backing plate 7 is removed, then knee control lift lever 6 is got back to the position of representing with solid line of Figure 13.Thereby the height of pressing element 5 is got back to the position of the height h2 of Fig. 7 B once more.
Fig. 7 C is the side view that the downside that is illustrated in pressing element 5 has been placed the state of 3 cloth 53.The state of this figure is not the state that cloth 53 lifts pressing element 5, but 3 cloth are placed on the highly state of the downside of the locational pressing element 5 of h2 that is held in.Thereby the state of Fig. 7 C is cloth 53 not to be applied the state of thrust of pressing element 5 or the state that thrust is suppressed enough for a short time.Thereby, then same if under the state of Fig. 7 C, begin to make with the situation that two cloth are made, help preventing that seam is partially.
