Eedle on the sewing-machine rotating shuttle that prior art document 1 is put down in writing bears in the mechanism, according to the eedle thickness of using, adjustment screw is tightened or loosens with manual operation.Adjustment screw and make it twist too tightly, regulate eedle bear portion and fixedly eedle bear the interval of portion can be very narrow, the spur interference (collision) of the eedle of decline and rotation can cause that eedle is bent or breakage etc.
In general, adopt the occasion of rotating shuttle, the shuttle axle is connected by the coupling component that is arranged on the positive back side of rotating shuttle with lower shaft.The eedle receiving plate is screwed on screw from the back side of outer shuttle.At the back side of eedle receiving plate (side of coupling component) adjustment screw is housed.Therefore exist coupling component to hinder the problem of the adjusting work of adjustment screw sometimes.
Summary of the invention
Even the object of the present invention is to provide a kind of eedle to be replaced with the different occasion of thickness, also can regulate the rotating shuttle device in the gap between eedle and the spur easily with use.
Rotating shuttle device of the present invention is arranged on the downside of Sewing machines needle plate, it comprises that outer shuttle has spur and the rotatably mounted interior shuttle of described outer shuttle with the rotation of lower shaft one of moving up and down synchronously with eedle, it is characterized in that: have eedle bear member be set to described outer shuttle and described in the other member of shuttle, it is to make described eedle guiding the stipulated time of described spur before being about to interlace with described eedle and the gap of regulating described eedle and described spur at least that described eedle bears member.And outside described shuttle or with described outside be provided with the position adjustments fixed mechanism on the member of shuttle one rotation, described position adjustments fixed mechanism makes described eedle be installed in the axis direction of described lower shaft with bearing the member adjustable position.
Constitute according to this,, also can regulate eedle and bear the position of member along the axis direction of lower shaft by the position adjustments fixed mechanism even operating personnel are replaced with the different occasion of thickness with the eedle that uses.
It is to make the eedle guiding stipulated time of spur before being about to interlace with eedle and the gap of adjusting eedle and spur, therefore easy eedle and the spur gap regulated at least that eedle bears member.
To also can be the coupling component that is connected described lower shaft and described outer shuttle with the member of outer shuttle one rotation.Constitute according to this, needn't prepare to be used for the parts that fixed mechanism is regulated in the installation site again.
Bear at eedle that the formation tabular eedle relative with described eedle bears portion on the member, bear the end height of portion about eedle, the end that preferably forms near spur is higher than from spur end far away.
When arriving eedle from the end that the eedle of a spur side far away bears portion and falling, eedle is positioned at roughly minimum point.Therefore eedle bear the high more eedle of height of portion and contact portion that eedle bears portion big more.Along with eedle and eedle bear the increase of the contact portion of portion, the heat that friction is produced also increases thereupon, and then might cause the distortion of eedle.
Though bear the height of portion by reducing eedle, can the contact portion that makes eedle bear portion and eedle reduces.But on the other hand, because eedle rises in the close spur end that eedle bears portion, the height that makes pin bear portion reduces, and can't carry out the guiding of eedle.Therefore raising of close the spur end height by bearing portion at eedle just guides eedle reliably.
Also can be such structure, promptly, the end that eedle bears the close spur of portion roughly is positioned at described spur place on the axis direction of lower shaft, be positioned on the axis direction of end at described lower shaft of portion than described spur also near described shuttle one side and bear from described spur eedle far away.
According to this formation, at the axis direction of lower shaft, eedle little by little is directed along the end of bearing the close spur of portion from spur end far away to eedle of bearing portion from eedle and becomes the height roughly the same ideal position of upper thread (spur catch) with spur.
Eedle can bear at eedle and eedle and hold sufficient gap between the portion, and then eedle more easily is directed along the eedle portion of bearing when near the state the end of bearing portion from spur eedle far away.
Baffle plate has incision hole, and described baffle plate is arranged on the rear side of outer shuttle and is somebody's turn to do outer shuttle one, and the portion of also eedle can being born inserts logical to incision hole from rear side.Constitute according to this, can realize that eedle bears the miniaturization of member.
The position adjustments fixed mechanism also can have bindiny mechanism, and described bindiny mechanism can fix and remove and be fixed on eedle and bear fixed part and the coupling component that forms on the member.Constitute according to this, remove at eedle by bindiny mechanism and bear the fixing of the fixed part that forms on the member and coupling component, and can adjust the position of bearing member with respect to the eedle of coupling component.Afterwards, can eedle be born member in adjusted position by bindiny mechanism and be fixed on coupling component.
In the position adjustments fixed mechanism, can on described coupling component, be provided with guide surface, thus, removed by bindiny mechanism between fixed part and the coupling component fixedly the time, this guide surface can be with respect to coupling component on the axis direction of lower shaft, promptly be parallel on the direction of coupling component and guiding fixed part.According to this formation, operating personnel can be after removing fixing between fixed part and the coupling component by bindiny mechanism, fixed part is moved along the guide surface (abreast) of coupling component, thereby can regulate fixed part in the position on the axis direction of lower shaft.
Fixed part is meant along the meaning that the axis direction of lower shaft moves abreast, for example, makes fixed part keep moving, or make and hold the gap between fixed part and the coupling component and move with contacting of coupling component.Bindiny mechanism constitutes like this,, is provided with slotted hole on the either party of fixed part and coupling component that is, utilizes thread mechanism via described slotted hole a described side and described the opposing party to be fixed together.According to this formation, bindiny mechanism can have simple formation.
The occasion of using the different eedles of thickness to make, as long as operating personnel loosen screw, just can with fixed part to the slotted hole direction, be that the axis direction of lower shaft carries out position adjustments simply.Because, can improve the operation of tightening or loosen operation of screw with the formation of screw-driving to the screw hole of coupling component.
Also can on coupling component, form incised notch portion, the part that described incised notch portion is removed for the axis direction along described lower shaft, and in incised notch portion, form guide surface.Constitute according to this, do not need other member to be set, and can carry out tightening of screw easily and loosen operation from the side of connecting elements for forming guide surface.
Eedle bear member also passable be that spur guides eedle in the specified time limit before being about to interlace with eedle, and guide eedle in the specified time limit after just interlacing.Constitute according to this, catch the front and back of upper thread, can prevent the vibration of eedle and carry out the seizure of upper thread more reliably at spur.

The shuttle axle 15 that outer shuttle 11 has outer shuttle body 14 and connects outer shuttle body 14.Coupling component 5 will transmit shuttle axle 15 with the revolving force of the synchronous lower shaft 4 that rotates of main shaft (not shown).Outer shuttle 11 and coupling component 5 are rotated integratedly.By transmitting revolving force to shuttle axle 15, making outer shuttle 11 is that the axle center is rotated with shuttle axle 15 synchronously with moving up and down of eedle 3, and its direction of rotation is, (that is, the direction rear is seen in the past, wherein from the front, the left side of Fig. 1 is the place ahead, and the downside of Fig. 3 is the place ahead) be rotated in a clockwise direction.Form spur 11a outside on the shuttle body 14 towards clockwise direction of rotation.
Rotation by lower shaft 4 after vertical rotating shuttle 10 transmits revolving forces, at interior shuttle 12 and shuttle sleeve under the state in spline, the synchronously rotation that moves up and down of outer shuttle 11 and eedle 3, its direction of rotation is for seeing the clockwise direction rotation from the front.By the rotation of outer shuttle 11, spur 11a catches from the extended upper thread of pin hole 3a (not shown) of the eedle 3 that passes processing cloth, and around interior shuttle 12, carry out around.Interweave from the eedle extended upper thread of 3 pin hole 3a with from the extended bottom line of bottom line shuttle (not shown).Strain the upper thread ring by thread take-up tension lever (not shown) then, thereby form stitching.
As shown in Figure 2, wire loop baffle plate 13 is the board members that surround the roughly semi-circular shape of lower shaft 4, and by hold-down screw 19 (example of screw member) rear side of shuttle 11 outside coupling component 5 one sides (rear side) are fixed on.As shown in Figure 1, be formed with the eedle that eedle 3 is entered between the rear surface of shuttle 11 and the wire loop baffle plate 13 outside and enter gap S.As shown in Figure 2, on wire loop baffle plate 13, be formed with the incision hole 13a of Rack.During before being about to arrive lowest point, just interlacing the rotation of the outer shuttle 11 after (distance the shortest) between the two with spur 11a to eedle 3 since eedle 3, the leading section of incision hole 13a and eedle 3 relative to.
The following describes and bear member as eedle and be arranged on the eedle receiving plate 20 of outer shuttle 11.
As shown in Figure 4, eedle receiving plate 20 sees that from the side (in Fig. 4, the left side is the place ahead) is step-like board member, is formed with the fixed part 20a along fore-and-aft direction on the right part of eedle receiving plate 20.Be formed with eedle and bear the 20c of portion on the upper end, the place ahead of eedle receiving plate 20, the left and right sides width that eedle bears the 20c of portion is narrower than the incision hole 13a of wire loop baffle plate 13 a little.The meaning that eedle bears the left and right directions of the 20c of portion is meant along the direction of the direction of rotation of outer shuttle 11.On fixed part 20a, be formed with the slotted hole 20b that extends along fore-and-aft direction.
As Fig. 2, shown in 4, eedle bears the roughly curved shape in end of the 20c of portion, and for the height that eedle bears the 20c of portion, is lower than the end of close spur 11a from spur 11a end far away.The meaning of end that eedle bears the close spur 11a of the 20c of portion is meant among eedle bears the described left and right end portions of the 20c of portion, the end of the upstream portion of the direction of rotation of shuttle 11 outside, because the spur 11a of outer shuttle 11 is when lower shaft rotates, arrive the end of this upstream portion earlier, so the end of this upstream portion is become the end of close spur 11a.Otherwise, the meaning of bearing the end of the 20c of portion from spur 11a eedle far away is meant among eedle bears the described left and right end portions of the 20c of portion, the end of the downstream portion of the direction of rotation of shuttle 11 outside, because the spur 11a of outer shuttle 11 is when lower shaft rotates, with upstream portion the end compare the end in this downstream of later arrival, so the end of this downstream portion is become from spur 11a end far away.Move to the specified time limit of the position (with reference to Fig. 6) after just interlacing from lowest point (with reference to Fig. 5) rising (with reference to Fig. 2) (for spur is about to interlace specified time limit before with eedle at eedle 3 with spur 11a, and the stipulated time after just having interlaced) in, the leading section (bottom) of eedle receiving plate 20 guiding eedles 3.Under state shown in Figure 5 (eedle 3 is at the state of lowest point), are about 50 degree corresponding to the anglec of rotation scope of the outer shuttle 11 that interlaces up to spur 11a and eedle 3.
Eedle receiving plate 20 favours the plane with the shuttle orthogonal of lower shaft 4.Shown in Fig. 3,4, on the axis direction of lower shaft 4, eedle bears being positioned at than more close shuttle 12 1 sides of spur 11a (front side) from spur 11a end far away of the 20c of portion, is positioned at the position roughly the same with spur 11a and pin bears the end of close spur 11a of the 20c of portion.As shown in Figure 1, 2, eedle bears the 20c of portion under the state of the incision hole 13a that passes wire loop baffle plate 13 from rear side, is positioned at eedle and enters gap S.Here the pin end of close spur 11a of bearing the 20c of portion is positioned at the position roughly the same with spur 11a, its meaning refers to, the end of close spur 11a that pin bears the 20c of portion can be positioned at than spur 11a a little near shuttle 12 1 sides (front side), and the end of close spur 11a that pin bears the 20c of portion also can be positioned at close a little lower shaft 4 one sides (rear side) than spur 11a.
The following describes position adjustments fixed mechanism 22.Can regulate eedle receiving plate 20 by position adjustments fixed mechanism 22 and enter among the S of gap position on the fore-and-aft direction (axis direction of lower shaft 4), and can be installed on the coupling component 5 regulating eedle receiving plate 20 at eedle.
As shown in Figure 2, the part on right side is formed with the 5a of incised notch portion a little in the upper end of coupling component 5, and the 5a of this incised notch portion is for along rectangular the part that forms of incised notch of the axis direction (fore-and-aft direction) of lower shaft 4.The fixed part 20a of eedle receiving plate 20 is extending upward in front and back along the longitudinal wall of the 5a of incised notch portion, and is configured as vertical posture on above-below direction.Be fixed on the longitudinal wall of the 5a of incised notch portion by hold-down screw (example of screw member) 23 screw threads that will pass slotted hole 20b, can regulate eedle receiving plate 20 position with respect to coupling component 5 on fore-and-aft direction, and eedle receiving plate 20 can be installed on the coupling component 5.Here, the fixed part 20a that forms on the eedle receiving plate 20 and coupling component 5 can be fixed together and can remove this and be fixedly coupled mechanism and comprise: the screwed hole 25 of the slotted hole 20b of fixed part 20a, hold-down screw 23 and coupling component 5.The incised notch angle that forms the incised notch 5a of portion is not limited to the right angle.On the 5a of incised notch portion, be formed with the guide surface that guides described fixed part 20a along the axis direction of described lower shaft 4, just to guide described fixed part 20a with respect to described coupling component 5 parallel modes.Hold-down screw 23 and screwed hole 25 constitute thread mechanism.
The following describes the effect of vertical rotating shuttle 10 with said structure.
Operating personnel earlier according to making as the thickness of the processing cloth of object and the eedle 3 that kind is selected suitable thickness, and were installed in shank 2 with eedle 3 before beginning to make.Then, the handwheel (not shown) of operating personnel's manual operation Sewing machines makes eedle 3 move the state (with reference to Fig. 6) after eedle 3 just interlaces with spur 11a downwards.Under this state, operating personnel's tool using unclamps hold-down screw 23, regulate the position of eedle receiving plate 20 then, so that the gap between eedle 3 and the spur 11a becomes specified gap (promptly, according to eedle 3 thicknesses of using, make eedle bear the leading section of the 20c of portion) from spur 11a guiding eedle 3 in one side direction rear, end far away.At last, after the position adjustments of finishing eedle receiving plate 20, tighten hold-down screw 23.
After the position of regulating eedle receiving plate 20, eedle bears being positioned at than more close shuttle 12 1 sides of spur 11a (front side) from spur 11a end far away of the 20c of portion on fore-and-aft direction (axis direction of lower shaft 4).The end of close spur 11a that pin bears the 20c of portion is positioned at roughly identical with spur 11a position on fore-and-aft direction (axis direction of lower shaft 4).
After the front and back position of regulating eedle receiving plate 20, operating personnel will process cloth and be placed on the needle plate 1, begin to make.Afterwards, each link of making, the eedle of eedle receiving plate 20 bears the 20c of portion during specified time limit (that is, rising to the time of the position (with reference to Fig. 6) after just having met with spur 11a from eedle 3 from lowest point (with reference to Fig. 5))) in the leading section of eedle 3 is rearward guided.Thereby avoid the interference of eedle 3 and spur 11a.
As described above, according to present embodiment, even under operating personnel change the outfit the occasion of the different eedle 3 of fineness degree, also can regulate the position of eedle receiving plate 20 on the axis direction of lower shaft 4 by position adjustments fixed mechanism 22.And then, by making eedle receiving plate 20 vectoring aircraft pin 3 rearward in the specified time limit before spur 11a and eedle 3 are about to interlace at least, can easily regulate the gap between eedle 3 and the spur 11a.
The integrally formed fixed part 20a that is used to install this eedle receiving plate 20 on eedle receiving plate 20, and on fixed part 20a, form the slotted hole 20b that extends along the axis direction of lower shaft 4.
According to position adjustments fixed mechanism 22, can eedle receiving plate 20 be fixed on the coupling component 5 that lower shaft 4 and outer shuttle 11 are linked together in the mode that can regulate relative position by passing the hold-down screw 23 of fixed part 20a and slotted hole 20b.Thereby can simplify the formation of position adjustments fixed mechanism 22.
Even,, just can regulate the position of eedle receiving plate 20 simply along the direction (being the axis direction of lower shaft 4) of slotted hole 20b as long as operating personnel unclamp hold-down screw 23 using the different eedle 3 of thickness to make under the occasion.And then, because only adopted, can improve fixing eedle receiving plate 20 and remove this fixing operability by hold-down screw 23 being tightened in the formation on the coupling component 5.
Eedle bears the 20c of portion and roughly forms curve-like, and for the height at two ends that eedle bears the 20c of portion, be lower than the end of close spur 11a from spur 11a end far away, thereby make this eedle bear the leading section of the 20c of portion guiding eedle 3 by this structure.According to the rising of eedle 3, eedle bears the 20c of portion at least can be at the leading section that specified time limit guide eedle 3 of eedle 3 before being about to interlace with spur 11a.Thus, make spur 11a not be subjected to the interference that eedle bears the 20c of portion, thus the upper thread that spur 11a is stretched out from the pinprick 3a of eedle 3 on the hook reliably, and then can avoid bouncing pilotage takes place and form stitching neat and attractive in appearance successively.
On coupling component 5, form along the axis direction of lower shaft 4 and extend and rectangular the 5a of incised notch portion of incised notch, and on the 5a of incised notch portion, form guide surface.Thus, position adjustments fixed mechanism 22 can be fixed on the mode of eedle receiving plate 20 with adjustable position on the 5a of incised notch portion by hold-down screw 23.Thereby can easily carry out tightening or/and loosening operation of hold-down screw 23 from the side of coupling component 5.The meaning of adjustable position refers to it is that operating personnel can loosen hold-down screw 23, and the fixed part 20a that makes eedle receiving plate 20 thus becomes possible state along the axis direction of lower shaft 4 mobile.This is parallel to move can be to make fixed part keep moving with the contact condition of the 5a of incised notch portion of coupling component 5, or makes and maintain the gap between the 5a of incised notch portion of fixed part and coupling component 5 and move.
The wire loop baffle plate 13 that will have incision hole 13a is wholely set the rear side of shuttle 11 outside, and from rear side the eedle of eedle receiving plate 20 is born the 20c of portion and pass incision hole 13a, therefore can realize the miniaturization of eedle receiving plate 20.
The present invention is not limited to above-mentioned embodiment, can also do various changes in the category that claim contained.
For example, as the eedle of eedle receiving plate 20 bear the 20c of portion guiding eedle 3 during, also can for spur 11a and eedle 3 specified time limit before being about to interlace (corresponding to the anglec of rotation of outer shuttle 11, for spur 11a and eedle 3 interlace before about 10 degree during), and spur 11a and eedle 3 specified time limit after just having met (corresponding to the anglec of rotation of outer shuttle 11, for spur 11a and eedle 3 meet afterwards about 10 spend during).
In present embodiment, the starting position of specified time limit is the lowest point of eedle 3.Be positioned at and be about to arrive position before the minimum point but also can get eedle 3, perhaps eedle 3 is positioned at the position that just arrives after the minimum point.
The enterprising rower of either party of also can be at the fixed part 20a of eedle receiving plate 20 and being used for installing the coupling component 5 of this eedle receiving plate 20 shows scale, and indicates datum line on the opposing party in fixed part 20a and coupling component 5.Constitute according to this, can confirm the gap size between eedle 3 and the spur 11a easily, thereby can mix up the position relation between scale and the datum line easily corresponding to the eedle of in the middle of the different multiple eedle 3 of thickness, selecting for use 3.
Also the fixed part 20a of eedle receiving plate 20 can be installed on the outer shuttle 11.
Also can make eedle receiving plate 20 be formed on to overlook around the wire loop baffle plate 13 and see the shape that is crooked, and eedle receiving plate 20 moves into the outside of wire loop baffle plate 13 and is positioned at eedle and enters gap S from fixed part 20a with the U font.
Though comprise the screwed hole 25 of fixed part 20a, slotted hole 20b, hold-down screw 23 and coupling component 5 as the bindiny mechanism of present embodiment, also can remove this fixing formation as long as fixed part 20a and coupling component 5 are fixed together.
For example, can on coupling component 5, form slotted hole 20b, be provided with the bolt that passes slotted hole 20b at fixed part 20a.In this occasion, at the opposite side opposite, by nut screwing clamping also can be fixed on fixed part 20a on the coupling component on this bolt with a side of inserting bolt.
