Fig. 3 is the stereogram from the being seen holder part in top.In addition, in Fig. 3, to have taken off the state of guard shield, represent Sewing machines framework 110.
As shown in Figure 3, in arm 114, along the bearing of trend machine spindle (with reference to Fig. 3) 130 of arm 114, by axle, supported.On machine spindle 130 end 131 (with reference to Fig. 5) outstanding to the outside of arm 114, gear 150 is set.Machine spindle 130, in arm 114, is arranged on the link such as not shown driving mechanism, cloth presser 134 of the needle bar 132 of head 118 with driving.In addition, machine spindle 130 is via the not shown lower shaft driving mechanism being arranged in uprights 116, the not shown lower shaft of drive arrangements in support portion.By the driving of this lower shaft, not shown looper etc. roll off the production line let-off gear(stand) and along the length direction of support portion send not shown each portions such as feed mechanism of dress material and the driving of needle bar 132 (with reference to Fig. 1) driven in linkage.
At the sweep of arm 114, along the bearing of trend of arm 114, fixed drive motors 140.The rotating shaft of this drive motors 140 and machine spindle 130 are configured on same axis, and link in same axle center via being arranged on to the gear 150 of the end 131 (with reference to Fig. 5) of the outer outstanding machine spindle 130 of arm 114.
By the driving of this drive motors 140, machine spindle 130 rotations, arm-outtake type sewing machine 10 drives.
In addition, machine spindle 130 is via driving belt transmission device 250, link with the power transmission shaft 170 by support 120 axles supportings, described driving belt transmission device 250 by the gear 150 of end 131 (with reference to Fig. 5), be arranged on the travelling gear 180 on power transmission shaft 170 and the endless belt 160 that is hung on described gear 150 and travelling gear 180 forms.
Well-known one-way clutch is between gear 150 and main shaft 130, particularly, gear 150 consists of the band one-way clutch gear with one-way clutch portion, and directionally during the direction of rotation (hereinafter referred to as being rotated in the forward) of the assembled so that machine spindle 130 driving at the drive motors 140 by when running, machine spindle 130 is for gear 150 idle running, and described in when being rotated in the forward of described gear, machine spindle and described gear rotate integratedly.
With one-way clutch gear, be gear 150 and travelling gear 180 and be hung on gear 150 and the endless belt of travelling gear 180 160 formation driving belt transmission devices 250.Driving belt transmission device 250, via gear 150, endless belt 160 and travelling gear 180, passes to machine spindle 130 by being rotated in the forward of power transmission shaft 170.
That is to say, gear 150 is that being rotated in the forward of power transmission shaft 170 being produced by hand rotating pulley 190 passed to machine spindle 130, and being rotated in the forward of machine spindle 130 is not passed to the gear of endless belt 160.
That is to say, when the driving by drive motors 140 is rotated in the forward the rotating shaft of drive motors 140, being rotated in the forward for gear 150 idle running of being reeled by endless belt 160 of drive motors 140, only passes to the machine spindle 130 with rotating shaft combination on same axle of drive motors 140 by the rotation of drive motors 140.
Make the shape of support 120 for extending obliquely upward from the bottom 121 being fixed on board, the leading section 122 extending is upward fixed on the base station side of head 118 in arm 114.That is to say, support 120 is the position in the contrary direction of the bending direction with head 118 from arm 114, in the mode of extending downwards, arm 114 is fixed on board and (omits diagram).
As shown in Figure 3, parallel with machine spindle 130 here by the power transmission shaft 170 of these support 120 axle supportings, be configured to extend on the width of support 120.
The both ends of power transmission shaft 170 are configured to from the two sides of support 120 in the face of outside.Hand rotating pulley 190 has been fixed in an end 174 (with reference to Fig. 4) at power transmission shaft 170, and at the fixing travelling gear 180 that has been hung endless belt 160 in the other end 172 of power transmission shaft 170.
Hand rotating pulley 190, in support 120, is configured on the side 124 of uprights 116 sides, and is exposed to outside.Hand rotating pulley 190 and power transmission shaft 170 rotate integratedly.
As shown in Figure 4, in arm-outtake type sewing machine 10, in order to prevent the rotation of hand rotating pulley 190, be provided with the moment appendix 200 of opponent's rotating pulley 190 additional moments.In addition, Fig. 4 represents to take off from hand rotating pulley the state of moment appendix.
By one-way clutch portion, be assembled into being rotated in the forward for gear 150 idle running of machine spindle 130, but in when Sewing machines High Rotation Speed etc. due to the Micro-friction of machine spindle 130 and gear 150, gear 150 rotations, prevent from via driving belt transmission device 250, the pulley 190 that is arranged on power transmission shaft 170 being rotated, moment appendix 200 prevents this situation.
Here, using force application part is that helical spring 202 is as moment appendix 200.
Centre at hand rotating pulley 190, be formed on the screw hole that surface has the depressed part 192 of concavity, helical spring 202 under the state between the flange 194a of screw 194 and the bottom surface of depressed part 192 by screwing screw 194, hand rotating pulley 190 is fixed on an end 174 of the power transmission shaft 170 that inserts this screw hole.That is to say, hand rotating pulley 190 screws an end 174 that is fixed on power transmission shaft 170 via helical spring 202 and by screw 194, thereby flange 194a presses helical spring 202, and the helical spring 202 being pressed is pressed depressed part 192.Thus, hand rotating pulley 190 becomes following state, and, by helical spring 202, this hand rotating pulley 190 is pressed to the side 124 of support 120.Therefore, hand rotating pulley 190 is by additional moment, and this moment prevents the rotation that the revolving force of the machine spindle 130 that the Micro-friction due to machine spindle 130 and gear 150 transmits causes.Moment when in addition, this is pressed is less than the moment that user rotates hand rotating pulley 190.In addition, adopted and used helical spring 202 as the structure of moment appendix 200, but be not limited to this.As long as by opponent's rotating pulley 190 additional moments, the rotation always of the hand rotating pulley 190 while preventing Sewing machines running, can adopt any structure to form moment appendix 200.
Then, use Fig. 5 that the action of the arm-outtake type sewing machine of present embodiment is described.
In Fig. 5, with arrow D1, be illustrated in the rotation of the travelling gear 180 when hand rotating pulley 190 is rotated in the forward, with arrow D2, represent the now rotation of endless belt 160, with arrow D3, represent with one-way clutch gear to be the rotation of gear 150.In addition, Fig. 5 be in order conveniently to unload drive motors from the being seen arm-outtake type sewing machine 10 of bearing of trend side of arm 114, and be from the being seen figure of side 126 side of side 124 opposition sides of the face with sewer's side in support 120.
Here, as mentioned above, in arm-outtake type sewing machine 10 is that gear 150 is directionally assembled into the end 131 of machine spindle 130 and the rotating shaft of drive motors 140 with one-way clutch gear, dallies with the direction of rotation of the machine spindle 130 when Sewing machines turns round (following for being rotated in the forward) time.In addition, in addition, use moment appendix 200 (helical spring 202 shown in Fig. 4) opponent's rotating pulley 190 more additional moments in advance.Thus, when Sewing machines turns round, when machine spindle 130 dallies for gear 150, even because the Micro-friction of machine spindle and gear makes swing pinion 150 rotations, hand rotating pulley 190 does not rotate yet.Thus, even when unidirectional clutch type gear is the idle running of gear 150, hand rotating pulley 190 does not rotate yet.
Thus, can drive arm-outtake type sewing machine 10 and can not make hand rotating pulley 190 rotation, and can make operation and need not take notice of that hand-screw turns pulley 190.
On the other hand, when operator rotating pulley 190, during along 190 rotation of arrow D1 direction hand rotating pulley, power transmission shaft is also along D1 direction rotation.In company with this rotation, endless belt 160 moves along arrow D2 direction, in company with this, moves, and the rotation of arrow D3 direction is delivered to gear 150.
Now, the machine spindle 130 linking with gear 150 now will stop, and that is to say, for gear 150, counter-rotating.The action of this counter-rotating is by the one-way clutch of gear and machine spindle 130 links is pinned.Thus, only, when along arrow D1 direction rotation hand rotating pulley 190, hand rotating pulley 190 can link and its revolving force is passed to machine spindle 130 with machine spindle 130.
Like this, in the arm-outtake type sewing machine 10 of present embodiment, in interior machine spindle 130 rotations of arm 114, freely by axle, supported, the end of this machine spindle 130 is outstanding to the outside of arm 114, and is provided with gear 150 thereon.In addition, machine spindle 130 is driven rotatably by drive motors 140, at support 120 intermediate solid drive shafts 170 that arm 114 are fixed on board, by axle, supported, in an end 174 of described power transmission shaft 170, hand rotating pulley 190 is set and in its other end 172, travelling gear 180 is set.And then, on the gear 150 of end 131 of machine spindle 130 and the travelling gear 180 of the other end 172 of power transmission shaft 170, hang endless belt 160.Gear 150 links with machine spindle 130 via one-way clutch portion.By this structure, when machine spindle 130 is rotated in the forward, because described machine spindle 130 is for described gear 150 idle running, so being rotated in the forward of machine spindle 130 is not delivered to hand rotating pulley 190.On the other hand, while gear 150 being rotated in the forward by being rotated in the forward of hand rotating pulley 190, because machine spindle 130 and described gear 150 rotate integratedly, so being rotated in the forward of hand rotating pulley 190 is delivered to machine spindle 130 via driving belt transmission device 250.
Thus, during Sewing machines running, hand rotating pulley 190 does not rotate, so can avoid hair or finger to be involved in the danger of hand rotating pulley 190, guarantees security.That is to say, when Sewing machines turns round, can make operation securely and need not take notice of that hand-screw turns pulley 190.In addition, in said structure, during Sewing machines running, endless belt 160 is not rotated yet, so can extend the life-span of endless belt 160 own.
And then, without for covering the driving belt guard shield of endless belt 160 or for covering the pulley guide shield of hand rotating pulley 190, thereby can realize cost, decline.
In addition, from in the past different, via gear and the endless belt rotation of the machine spindle of self-driven motor in the future, passing in the mechanism of manual knob (hand rotating pulley), according to present embodiment, can only when operator rotating pulley 190, make hand rotating pulley 190 rotation, and the loaded down with trivial details operation being rotated when not needing to press manual knob etc.
In addition, in the present embodiment, one-way clutch portion has adopted the structure of the linking portion that is arranged on machine spindle 130 and gear 150, but the structure of rotating so long as hand rotating pulley 190 is not followed the rotation of machine spindle 130, be not limited to the structure of present embodiment, can carry out any setting.In other words, in arm-outtake type sewing machine, as long as adopt, there is the structure that the rotation of hand rotating pulley 190 is passed to the one-way clutch portion of machine spindle 130, can adopt any structure.In addition, also can, via one-way clutch portion, at least one party in gear 150 and travelling gear 180 be linked with machine spindle 130 or power transmission shaft 170.
Fig. 6 to Fig. 8 means the figure of variation of the arm-outtake type sewing machine of present embodiment, and it is illustrated respectively in the mechanism's part that is delivered to hand rotating pulley 190 in each arm-outtake type sewing machine from the power of machine spindle 130.
In addition, these have same basic structure from the corresponding arm-outtake type sewing machine 10 of an embodiment shown in arm-outtake type sewing machine 10A, 10B, 10C and the Fig. 1 shown in Fig. 6 to Fig. 8, to the additional same label of same structural element, and the description thereof will be omitted.
As shown in the arm-outtake type sewing machine 10A of Fig. 6, also can adopt following structure, travelling gear 180A links with power transmission shaft 170 via one-way clutch portion 210, gear 150A with machine spindle 130 links not via one-way clutch.In addition, in Fig. 6, the rotating shaft of drive motors 140 and machine spindle 130 combination on same axle.
Now, by being rotated in the forward of machine spindle 130, via driving belt transmission device 250, travelling gear 180A is when being rotated in the forward, travelling gear 180A is for power transmission shaft 170 idle running, so being rotated in the forward of machine spindle 130 is not delivered to hand rotating pulley 190.On the other hand, while power transmission shaft 170 being rotated in the forward by hand rotating pulley 190, because travelling gear 180A and power transmission shaft 170 rotate integratedly, so being rotated in the forward of hand rotating pulley 190 is delivered to machine spindle 130 via driving belt transmission device 250.In arm-outtake type sewing machine 10A, hand rotating pulley 190 has additional moment and prevents the moment appendix 200 (with reference to Fig. 4) of the rotation of described hand rotating pulley.
In addition, in the arm-outtake type sewing machine 10A of Fig. 6, also can adopt following structure, hand rotating pulley 190 links via one-way clutch portion and power transmission shaft 170, gear 150A and travelling gear 180A and machine spindle 130 and power transmission shaft 170 links and not via one-way clutch.Particularly, at the well-known one-way clutch of the joint portion of hand rotating pulley 190 and power transmission shaft 170 240 configuration.Now, when power transmission shaft 170 being rotated in the forward due to being rotated in the forward of machine spindle 130, power transmission shaft 170 is for 190 idle running of hand rotating pulley, so being rotated in the forward of machine spindle 130 is not delivered to hand rotating pulley 190.On the other hand, when hand rotating pulley 190 is rotated in the forward, hand rotating pulley 190 and power transmission shaft 170 rotate integratedly, so hand-screw turns 190 be rotated in the forward via driving belt transmission device 250 and be delivered to machine spindle 130.
And then, as shown in the arm-outtake type sewing machine 10B of Fig. 7, also can adopt following structure, drive motors 140 is fixed on support 140, by this rotating shaft 144 be arranged on the same axle of power transmission shaft 170 on.Now, also can adopt following structure, travelling gear 180A links via one-way clutch portion and drive motors axle, or hand rotating pulley 190 links via one-way clutch portion and power transmission shaft 170.Particularly, travelling gear 180A is by being with one-way clutch gear to form.According to this structure, being rotated in the forward via driving belt drive unit of drive motors 140, is delivered to machine spindle 130, but is not delivered to hand rotating pulley 190.
In addition, as shown in the arm-outtake type sewing machine 10C of Fig. 8, also can be in the one-way clutch portion 179 that arranges of the power transmission shaft 170A by support 120 axle supportings, the rotation of the hand rotating pulley 190 while preventing Sewing machines running midway.
That is to say, in arm-outtake type sewing machine 10C, power transmission shaft 170A is divided into axle (position of an end side) 176 and another distolateral (position of the other end side) 178 that is configured in the end side on same axis in support 120.Between the axle 176 of these end side and the axle 178 of the other end side, set up one-way clutch portion 179.Now, being rotated in the forward via driving belt transmission device 250 of drive motors 140, when an end side 178 that makes to have installed travelling gear is rotated in the forward, the axle 178 of one end side is for axle 176 idle running of the other end side, so being rotated in the forward of machine spindle 130 is not delivered to hand rotating pulley 190.On the other hand, while making axle 178 rotation of the other end side by being rotated in the forward of hand rotating pulley 190, the axle 176 of one end side and the axle 178 of the other end side rotate integratedly, so being rotated in the forward of hand rotating pulley 190 is delivered to machine spindle 130 via driving belt transmission device 250.The rotation of the hand rotating pulley 190 in the time of thus, can preventing Sewing machines running.
Like this, according to each variation, be arm-outtake type sewing machine 10A, 10B, 10C, when driving, Sewing machines can carry out safely operation, and manual rotation machine spindle easily as required.
