Rise through and be implemented as described below：As shown in fig. 6, tab 40a is to the direction (hereinafter referred to as contacting direction) contacted with contact site 41a
X is swung, and in the state of tab 40a is contacted with contact site 41a, oscillating structural member 40 lifts the other end of connecting rod 41.By the way
Once, as shown in figure 5, being fitted together to regulating bolt 51 on adjusting nut 52, so that pressing spring is pressed in the lower end pressing of regulating bolt 51
53.Rod 54 is compressed using the pressing of its elastic force by pressing spring 53, the lower end for compressing rod 54 presses the upper surface of guiding piece 45.Thus,
As shown in fig. 6, when tab 40a is swung to direction (hereinafter referred to as departure direction) Y left from contact site 41a, making
It will not also be left with piece 40a from contact site 41a.That is, contact site 41a follows tab 40a, and therefore, tab 40a
It is maintained with contact site 41a contact condition.The power for compressing the pressing guiding piece 45 of rod 54 can be by loosening adjusting nut 52, turning
Regulating bolt 51 is moved to adjust.To sum up, using adjoint the swing of upper feeding upper and lower axle 39, tab 40a to contact direction X's
Swing, the other end of connecting rod 41 is lifted, so that guiding piece 45 rises.In addition, by the pendulum with upper feeding upper and lower axle 39
Dynamic, tab 40a makes compression rod 54 press guiding piece 45 on the basis of departure direction Y swing, thus guiding piece 45 with
The other end of connecting rod 41 declines together.As described above, with oscillating structural member 40 the company under swing and swing effect
The other end of bar 41 is moved up and down, and upper feeding platform 4 moves up and down by guiding piece 45.Utilize above-mentioned front and rear drive mechanism 6
The synthesis moved up and down for the upper feeding platform 4 that the movable and upper lower drive mechanism 7 of the upper feeding platform 4 of progress is carried out, it is enterprising
Elliptic motion is carried out in the vertical plane along cloth conveying direction F to platform 4 and the upper feeding tooth 5 for being installed on upper feeding platform 4.
Symbol 63 shown in Fig. 4 is guiding elements 63, and frame 8 is fixed on using bolt 64.Guiding elements 63 is to guiding piece
45 move up and down is guided.Symbol 61 and symbol 62 are upper feeding platform guiding piece (right side) 61 and upper feeding platform guiding piece (left side)
62, the movable of upper feeding platform 4 and moving up and down is guided.Draw in upper feeding platform guiding piece (right side) 61 and upper feeding platform
The preceding surface of guiding element (left side) 62 is provided with groove, is fitted together to have in the cell and cuts oil ring 65, the insertion of upper feeding platform 4, which is embedded in, cuts oil ring 65
In.Moreover, cut oil ring guiding piece 66 is fixed on upper feeding platform guiding piece (right side) 61 using bolt 67,68.
Then, upper feeding platform hoisting mechanism 70 is illustrated.Fig. 7 is the major part section view for representing upper feeding platform hoisting mechanism 70
Figure.As shown in fig. 7, being fixed with the base portion of lifting arm 72 in the shaft end of cylinder axle 71.It should be noted that cylinder axle 71 and lifting arm 72
It can also be integrally formed.Lifting arm 72 extends from its base portion to front and is formed with arm 72a, and arm 72a runs through from rear
Upper feeding platform room 3 and be configured in upper feeding platform room 3.It is fitted together to have in arm 72a and cuts oil ring 73, upper feeding platform room 3 is closed.
Arm 72a front-end configuration is that can engage with the guiding groove 45a upper surfaces of guiding piece 45.In addition, from the base portion of lifting arm 72 to
Top extends and is formed with bar portion 72b, as shown in fig. 7, bar portion 72b is acted on by spring 74, so that lifting arm 72 and cylinder axle
71 are exerted a force clockwise together, are blocked by stop part 75.Bar portion 72b front-end configuration be frame 8 external energy with
It is fixed on the claw 77a engagings of the claw bar 77 of one end of action axle 76.The other end for acting axle 76 extends to the end through frame 8
The inside in portion 2, is configured to rotate.Inside on head 2, the base portion of crank 78 is fixed with the other end of action axle 76.It is bent
The linking part of handle 78 links with one end of connecting rod 79, and the linking part of claw bar 80 is linked with the other end of connecting rod 79.In claw bar 80
Claw 80a is formed with, claw 80a is configured in the vicinity of the slit 82 of the formation of cylinder 81.Cylinder 81 is supported on frame 8, in cylinder
Helical spring 83 is configured with body 81 and rod 84 is compressed.The front end of rod 84 is compressed to the outside prominent of frame 8, as shown in figure 1, sharp
Pressing table 85 is pressed with the elastic force of helical spring 83.Compressing member (not shown) is installed in the front end of pressing table 85.Compressing rod
Midway inside 84 head 2 is formed with holding section 84a.Holding section 84a rearward extends from rod 84 is compressed through slit 82, matches somebody with somebody
It is placed in the claw 80a of claw bar 80 top.The power for compressing the pressing pressing table 85 of rod 84 can be by loosening adjusting nut 86, rotating and adjust
Bolt 87 is saved to adjust.
As shown in figure 1, frame 8 of the upper feeding platform hoisting mechanism 70 outside head 2 possesses action bars 88.Action bars 88
Free end is formed extended at both sides upward from cardinal extremity.Pin 88a is formed with the cardinal extremity of action bars 88, pin 88a is configured through frame 8
In in head 2.As shown in fig. 7, being fixed with the base portion of claw bar 80 in pin 88a.By the way that the free end of action bars 88 is rearward pressed
Under, so that the rotating counterclockwise in Fig. 7 centered on pin 88a of claw bar 80, claw 80a and the holding section 84a cards for compressing rod 84
Close and lift compression rod 84, release the pressing to pressing table 85.In addition, by claw bar 80 centered on pin 88a it is inverse in Fig. 7
Hour hands are rotated, so that connecting rod 79, crank 78 and action axle 76 are swung, claw bar 77 is centered on acting axle 76 in Fig. 7
Rotate clockwise.Moreover, being engaged by the claw 77a of claw bar 77 with the bar portion 72b front ends of lifting arm 72 and lifting arm 72 is with cylinder
Rotating counterclockwise in Fig. 6 centered on axle 71, so that the arm 72a front ends of lifting arm 72 and the guiding groove 45a of guiding piece 45
Upper surface engages and lifts guiding piece 45 and upper feeding platform 4.Therefore, using the rotating operation of action bars 88, release to pressing table
85 pressing and upper feeding tooth 5 is set to increase.For example, lifting upper feeding platform 4 using upper feeding platform hoisting mechanism 70 in operator
In the case of, only upper feeding platform 4, guiding piece 45 and the connecting rod 41 interlocked using upper lower drive mechanism 7, therefore, operator is not
Need larger power and upper feeding platform 4 can be lifted.
The present invention is not limited to embodiments illustrated above, as long as those skilled in the art, can not depart from the present invention
Various changes are added in the range of purport to previous embodiment and are implemented, the present invention is also comprising such change mode.
