Section.
Specifically, feeder assembly is set to the top of workbench 12, upper layer cloth 02 and lower layer mix feeding 04 are placed in work
Make on platform 12, and feeder assembly can be rotated relative to workbench 12；Wherein, feeder assembly can be used upper layer cloth 02 and lower layer
Cloth 04 is pressed on table 12, and realizes upper layer cloth 02 under in such a way that feeder assembly is rotated relative to workbench 12
The feeding of layer cloth 04 can also stir upper layer cloth 02 and lower layer mix feeding 04 using shifting block 11, to realize upper layer cloth 02
With the feeding of lower layer mix feeding 04.
During the work time, feeder assembly can directly push down upper layer cloth 02 and lower layer mix feeding 04, when feeder assembly is opposite
When workbench 12 rotates, so that upper layer cloth 02 and lower layer mix feeding 04 are synchronized with feeder assembly movement namely upper layer cloth 02
It is moved with lower layer mix feeding 04 relative to workbench 12.
Friction component is set to the lower section of feeder assembly, it is clear that upper layer cloth 02 and lower layer mix feeding 04 should be arranged in friction component
Motion profile on, when upper layer cloth 02 and lower layer mix feeding 04 move to the position of friction component, friction component is to lower layer's cloth
Material 04 provides frictional force, and frictional force can be movable relatively lower layer mix feeding 04 relative to upper layer cloth 02, to adjust upper layer cloth
The positional relationship of material 02 and lower layer mix feeding 04 realizes alignment.
For feeder assembly, such as Figure of description 1 and attached drawing 2, power part 1 may be configured as rotating electric machine, and it is dynamic to provide rotation
Power, driving lever 9 are connected with power part 1, and driving lever 9 is located at the top of workbench 12, and driving lever 9 is parallel with workbench 12；Specifically, it dials
The first end of bar 9 can connection gear, the mode that the prior art can be used between gear and power part 1 realizes transmission；Piston cylinder 10
Set on driving lever 9, to provide downward pressure, column cap 8 connects piston cylinder 10, to move downward to push down 02 He of upper layer cloth
Lower layer mix feeding 04.Wherein, the center of circle of gear may be provided at eedle namely feeder assembly can be realized by way of pressure holding
The feeding of layer cloth 02 and lower layer mix feeding 04.
When realizing the feeding of upper layer cloth 02 and lower layer mix feeding 04 by the way of stirring for feeder assembly, driving lever 9 is also
It can be equipped with shifting block 11, shifting block 11 extends towards the direction of workbench 12, namely extends downward, to stir upper layer cloth
02, such as Figure of description 1 and attached drawing 2.More specifically, the first end of above-mentioned driving lever 9 may be defined as round end, driving lever 9 it is another
One end may be defined as elongated end, and column cap 8 and piston cylinder 10 are set to elongated end, and shifting block 11 is set between round end and elongated end.
In the motion process of feeder assembly, power part 1 drives driving lever 9 to rotate by the center of circle of eedle first, and driving lever 9 is equipped with
Column cap 8 and shifting block 11, the mountable friction pad 81 of column cap 8 provide frictional force to the upper surface to upper layer cloth 02.It was sewing
Cheng Zhong, when shifting block 11 drives upper layer cloth 02 and 04 synchronous rotary of lower layer mix feeding to certain position, the column cap 8 is in piston cylinder
Under the action of 10, upper layer cloth 02 and lower layer mix feeding 04 are pushed.That is, driving upper layer cloth 02 and lower layer mix feeding using shifting block 11
04 moves synchronously to predeterminated position, after upper layer cloth 02 and lower layer mix feeding 04 are moved synchronously to predeterminated position, friction component pair
Lower layer mix feeding 04 provides frictional force, under the action of frictional force, so that generating between upper layer cloth 02 and lower layer mix feeding 04 opposite
Movement, to realize alignment.
Certainly, no matter feeder assembly is by the way of pressure holding or the mode stirred realizes upper layer cloth 02 and lower layer mix feeding
04 feeding, feeder assembly can be provided with column cap 8 and driving lever 9 simultaneously, to be selected a good opportunity selection according to different operating conditions, as specification is attached
Shown in Fig. 1 and attached drawing 2.
For the specific set-up mode of friction component, as shown in Figure of description 1, friction plate 13 may be configured as, rub
Piece 13 is set to workbench 12, on the motion profile of upper layer cloth 02 and lower layer mix feeding 04.
In conjunction with Figure of description 3 and attached drawing 4, the stress relationship of this paper detailed analysis upper layer cloth 02 and lower layer mix feeding 04.
For processing collar, collar includes upper layer cloth 02 and lower layer mix feeding 04, and cloth 02 is stained with liner 01, lower layer's cloth at the middle and upper levels
The viscous lining of material 04, and the rilateral seam of upper layer cloth 02 and lower layer mix feeding 04 is combined that (one of long side is not sewn to one
It rises).
During the motion, column cap 8 provides directed force F straight down to upper layer cloth 02, and the bottom of column cap 8, which is equipped with, rubs
Scrubbing pad 81；When column cap 8, which is pressing against upper layer cloth 02 and lower layer mix feeding 04, to be moved on smooth workbench 12, due to upper layer cloth
The frictional force between frictional force and upper layer cloth 02 and lower layer mix feeding 04 between 02 and friction pad 81 is all larger than lower layer mix feeding
Frictional force between 04 and workbench 12, therefore upper layer cloth 02 and lower layer mix feeding 04 move synchronously, and the opposite changing of the relative positions does not occur.?
I.e., it is possible to regard workbench 12 and column cap 8 as with the mobile (V in such as Figure of description 3 of opposite speed1And V2), it is being moved through
Cheng Zhong, column cap 8 is motionless always with respect to upper layer cloth 02, and this requires the frictional force that upper layer cloth 02 is subject to be consistently less than lower layer's cloth
Friction sum suffered by material 04.
When upper layer cloth 02 and 04 synchronizing moving of lower layer mix feeding are to the position of friction plate 13, due to lower layer mix feeding 04 by
The frictional force that friction plate 13 provides, so that the force of sliding friction between lower layer mix feeding 04 and friction plate 13 is greater than liner 01 and lower layer
Maximum static friction force between cloth 04, and produce relative sliding namely lower layer mix feeding 04 relative to upper layer cloth 02 occur phase
To displacement.Due to relatively far away from, and being led due to the variation of frictional damping coefficient at some the off-seam line 03 of lower layer mix feeding 04
Cause lower layer mix feeding 04 that relative displacement occurs relative to upper layer cloth 02, such that lower layer mix feeding 04 is relative to upper layer cloth 02
Certain hysteresis quality occurs in movement speed, so that lower layer mix feeding 04 be made to be partially toward down relative to the leakage of upper layer cloth 02
The direction on the unstitched one side of layer cloth 04 is mobile, namely mobile towards the left side in Figure of description 3.
As shown in Figure of description 4, when lower layer mix feeding 04 is synchronous with upper layer cloth 02 in smooth the upper surface of workbench 12
When mobile, lower layer mix feeding 04 is by the frictional force F from workbench 121With upper layer cloth 02 to the frictional force F of lower layer mix feeding 044
Effect, due to lower layer mix feeding 04 with upper layer cloth 02 synchronous and uniform motion, at this time F1=F4.When column cap 8 is to upper layer cloth 02
The directed force F provided straight down is constant, when mobile column cap 8 passes through friction plate 13, that is, can produce extra frictional force F2, when
F2And F1Resultant force be more than F4When, lower layer mix feeding 04 starts opposite upper layer cloth 02 and slides, and sliding time passes through friction by column cap 8
The time of piece 13 determines.Assuming that frictional force F2It always exists, until upper layer cloth 02 and lower layer mix feeding 04 since splicing position is made
With upper layer cloth 02 generates directed force F to lower layer mix feeding 043, work as F3+F4=F1+F2When, can be realized lower layer mix feeding 04 relatively on
The automatic adjusument of layer cloth 02；That is the mistake that reaches a dynamic equilibrium under the action of above-mentioned various external force of lower layer mix feeding 04
Journey.
It is found by the above analysis, the automatic adjusument of Yao Shixian lower layer mix feeding 04 need to only realize F3+F4=F1+F2?.
Wherein, F4Size can start from scratch, the work of maximum value and liner 01, upper layer cloth 02, the material of lower layer mix feeding 04 and column cap 8
It is related with position, and F2Size can be adjusted by the size and the pressure size of column cap 8 for adjusting friction plate 13, realization compare
It is easier to, and has passed through verification experimental verification.
By above-mentioned it is found that driving both upper layer cloth 02 and lower layer mix feeding 04 synchronous relative to workbench in feeder assembly
During 12 movements, when both upper layer cloth 02 and lower layer mix feeding 04 are moved synchronously to friction plate 13, lower layer mix feeding 04 exists
It is moved under the action of friction plate 13 relative to upper layer cloth 02, to realize the alignment of upper layer cloth 02 and lower layer mix feeding 04.Specifically
Ground, in conjunction with Figure of description 1 and attached drawing 2, column cap 8 is pushed down upper layer cloth 02 and lower layer mix feeding 04 and is transported on smooth workbench 12
It is dynamic；At this point, the horizontal force that column cap 8 is applied to upper layer cloth 02 is consistent to the reaction force of upper layer cloth 02 with lower layer mix feeding 04,
So that upper layer cloth 02 and lower layer mix feeding 04 are moved synchronously with driving lever 9.
Pass through friction plate 13 during the motion, friction plate 13 gives effect of the bottom surface of lower layer mix feeding 04 towards first direction
Power, so that lower layer mix feeding 04 is moved relative to upper layer cloth 02 towards first direction, i.e., lower layer mix feeding 04 and upper layer cloth 02 are sent out
Raw relative displacement；Again because lower layer mix feeding 04 and upper layer cloth 02 are stitched together on one side, when lower layer mix feeding 04 and upper layer cloth
When material 02 splices the left side of suture on the right of the two, suture has given the power of lower layer mix feeding 04 to the right, prevents lower layer mix feeding
04 continues to be moved to the left, and the adjusting of lower layer mix feeding 04 is realized, as shown in Figure of description 3.
For friction component, it may also include movement wiping board 5 and pressing plate 3, movement wiping board 5 is to support lower layer mix feeding 04 and upper
Layer cloth 02, movement wiping board 5 can be moved relative to workbench 12, can be to lower layer mix feeding in the motion process of movement wiping board 5
04 provides frictional force.Pressing plate 3 is set to the top of movement wiping board 5, wipes upper layer cloth 02 and lower layer mix feeding 04 are pressed on movement
Plate 5；When upper layer cloth 02 and lower layer mix feeding 04 move to the top of movement wiping board 5, pressing plate 3 is by upper layer cloth 02 and lower layer's cloth
Material 04 is pressed on movement wiping board 5, and movement wiping board 5 is moved relative to workbench 12, phase under the action of moving wiping board 5 of lower layer mix feeding 04
Upper layer cloth 02 is moved, to realize the alignment of upper layer cloth 02 and lower layer mix feeding 04.
The motion principle for moving wiping board 5 and pressing plate 3 is for example similar as above, and details are not described herein again herein.In short, upper layer cloth
Material 02 and lower layer mix feeding 04 are adjusted during being fed by feeder assembly without alignment, and workbench 12 is not provided with movement wiping board
5, but when upper layer cloth 02 and lower layer mix feeding 04 move to the position of movement wiping board 5, it is applied using pressing plate 3 to upper layer cloth 02
Add active force, and move wiping board 5 and moved relative to lower layer mix feeding 04, so that lower layer mix feeding 04 is carried out autokinesis wiping board 5
Frictional force, lower layer mix feeding 04 relative to upper layer cloth 02 move, realize upper layer cloth 02 and lower layer mix feeding 04 alignment, namely
