The protuberance of intermediate member rise cam 9 (seeing Fig. 5 and 10) control intermediate member 3 makes it change between use location and standby position.When middle parts rise cam 9 is in the use location, can between pile yarns and non-pile yarns, selects, and, only can select non-pile yarns at standby position.
As in Fig. 5 and Figure 12, most clearly expressing, an electromagnetism selecting arrangement is housed in the sedimentation film trap in the periphery of intermediate member 3.Rocking bar supporting base 4 has at least one protuberance 4a, the triangle track T4 control that this protuberance 4a is formed by first intermediate cam 10 and second intermediate cam 11.
Towards described rocking bar 5, magnetic is installed on sinker cover 17 is closed device 13a, 13b (seeing Fig. 5 and Fig. 7).According to the previous output signal of determining that pattern-information provides, these magnetic attracting devices 13a, 13b be magnetic attracting face 5a, the 5b of adhesive rocking bar 5 optionally according to controller.Best, before rocking bar 5 is near magnetic attracting device 13a, 13b, and only work as rocking bar 5 in magnetic attracting device 13a, 13b, make the rocking bar 5 that freely rotates with reference to the 14 (see figure 5) levellings of rocking bar compensation triangle.Preferably a kind of nonmagnetic substance is used as the compensation triangle, so that reduce the full magnetic force of permanent magnet.
When improving sinker 2, send a signal to magnetic attracting device 13b by controller.So that the magnetic attracting face 5b (the B-B sectional drawing of seeing Fig. 5 is Fig. 7) that adhesive is corresponding with the magnetic attracting device 13b of rocking bar 5.At this moment, the sinker top 2f top feeding knitting needle 1 of filling GY and the described sinker 2 of process is provided by described filling feedway 6a.
After described magnetic attracting face 5b passes through magnetic attracting device 13b, the inclined wedge-shaped end 5d of rocking bar 5 combines with the face that the is inclined upwardly 12a with trapezoid cross section of rocking bar 31 pin triangles 12, and rocking bar 5 is pushed the center (the C-C sectional drawing of seeing Fig. 5 is Fig. 7) of knitting machine to protecting bar supporting base 4 then.
Be pushed the rear end 3b release of the leading edge 4b of the rocking bar supporting base 4 that shows with intermediate member 3.The protuberance 3a of intermediate member 3 combines with the face that the is inclined upwardly 9a of intermediate member rise cam 9, and intermediate member 3 is released (the D-D sectional drawing of seeing Fig. 5 is Fig. 9) towards the center of knitting machine.
The leading edge 3C of the intermediate member 3 that is pushed out releases the rear end 2C of sinker 2.When middle parts 3 arrived the end face 9b of intermediate member rise cam 9, the pars intermedia that is pushed out 3 a raising sinker 2 were on the position that can constitute looped pile on the sinker nose 2b (the E-E sectional drawing of seeing Fig. 5 is Figure 10 A).At this moment, pile yarns PY is provided and feeds knitting needle 1 by described pile yarns feedway 6b through the sinker top of described sinker 2 2b top.The sedimentation and 2 that Figure 11 (the F-F sectional drawing of Fig. 5) expression is enhanced is just forming the state of a looped pile PL on sinker nose 2b.
At the end face 9b place of intermediate member rise cam 9, preferably make the tip of nose 2b of the sinker 2 that is pushed out in place like this so that move in the circumference use location alignment of knitting needle 0.3 millimeter or more than.Selected like this, will guarantee that hair figure is formed on tip with sinker nose 2b and separates on 0.3 millimeter or the above position.
Utilizing after rocking bar supporting base 4 releases the position that combines with intermediate member rise cam 9 with intermediate member 3, the protuberance 4a of rocking bar supporting base 4 combines with the inclined-plane 10b that dips down of first intermediate cam 10, therefore makes rocking bar supporting base 4 and rocking bar 5 turn back to the position of no pile yams line together.
In said structure, can omit intermediate member 3 and intermediate member control triangle.In this case, rocking bar rise cam 12 is released rocking bar 5 and rocking bar supporting base 4 together, and rocking bar supporting base 4 is directly released sinker 2.
When not improving sinker 2, send a signal by controller to magnetic attracting device 13a, so that the magnetic attracting face 5a (see figure 7) of adhesive and the corresponding rocking bar 5 of magnetic attracting device 13a.In Fig. 7, simple because technical reason knows which magnetic attracting face of expression (5a or 5b) is not by the adhesive of which magnetic attracting device (13a or 13b) institute.
By the rocking bar 5 of magnetic attracting device 13a adhesive process below acclivitous 12a of the rocking bar rise cam 12 that does not have combination with it, and rocking bar 5, rocking bar supporting base 4 and intermediate member 3 advance along circumference, do not move (seeing Fig. 8 B, 9B and 10B) along direction from the beginning to the end.Sinker 2 does not combine with intermediate member 3, only by sinker cam 7 and 8 controls.At this moment, even pile yarns PY is provided, will be knitting on the 2f of sinker top, thereby can not form looped pile.Filling GY and pile yarns PY pass through the sinker top 2f top of described sinker 2, feeding knitting needle 1 (the E-E sectional drawing of seeing Fig. 5 is Figure 10 B) together
As mentioned above, utilize device for controlling sinker of the present invention, carry out the selection of pile yarns or non-pile yarns, form the jacquard weave fleece that has pattern according to pattern signal by controller output.
In the electromagnetism selecting arrangement shown in Fig. 1-4, the N pole-face of permanent magnet is outside, and the S pole-face is inside.When the device for controlling sinker in circular knitter was used this device, the magnetic pole that the residual flux that produces in rocking bar is crossed every another feedway of conversion prevented.At this moment, be applied to positive voltage on the electromagnet of every another feedway and negative voltage by conversion (for example, by terminal improved cross connect for first and second electromagnet of every another feedway arranged in series), can have identical polarity orientation from the use or the stand-by control signal of control device for each feedway.
The mean value of the magnetic flux density measurement result of expression electromagnetism selecting arrangement of the present invention in table 1.
