FLAT KNITTING MACHINE STRUCTURE WITH ADJUSTABLE GAP BETWEEN TWO KNOCK-OVER BITS

Description

FIELD OF THE INVENTION

[0001] The present invention relates to a flat knitting machine structure, and in particular to a flat knitting machine structure which can adjust the size of a gap through knock-over bits.

BACKGROUND OF THE INVENTION

[0002] The existing knitting of three-dimensional fabric with adjustable thickness is generally realized by a warp knitting machine, as disclosed in patents of CN 102704180A, CN 102978823A and CN 105220347A. Further prior art documents to be mentioned are: EP 1 340 847 A1; EP 0 533 414 A1 and EP 1 247 887 A1.

[0003] Thus, a flat knitting machine structure with an adjustable gap between two knock-over bits is known, the structure comprising: two needle beds comprising a plurality of needles, wherein each of the plurality of needles defines a needle extending line and comprises a butt which is positioned on the needle extending line; and two cam systems, respectively disposed to face one of the needle beds, wherein each of the cam systems comprises a needle cam to provide the butts being placed and guide each of the plurality of needles to make a knitting stroke towards the gap.

[0004] However, the problem that the existing flat knitting machine cannot knit the foregoing mentioned fabric results from the flat knitting machine comprising fixed knock-over bits to define a gap therebetween, which is causing that the flat knitting machine can only knit the fabric with a single thickness.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The details and technical contents of the present invention will be described below with reference to drawings.

[0015] Referring to Figs. 1, 2, 3, 4, 5, 6, 7, 8 and 9, the present invention provides a flat knitting machine structure 100 which is able to change the size of a gap 10 in accordance with knitting requirements during knitting process, so as to change the thickness of a three-dimensional fabric 90 (also called spacer fabric) in the knitting process. The flat knitting machine structure 100 includes two needle beds 11 and 12 and two cam systems 13(14) which are respectively disposed to face one of the needle beds 11(12). The two needle beds 11 and 12 mean a front needle bed and a rear needle bed in the current industry, wherein the two needle beds 11 and 12 are disposed in an inclined angle to correspond to each other. The two needle beds 11 and 12 are disposed at interval to form a space therebetween. Each of the needle beds 11(12) comprises a plurality of needles 15 and a plurality of knock-over bits 16 which are respectively disposed to correspond to each of the plurality of needles 15. The plurality of knock-over bits 16 of the present invention are not sinkers. Although the plurality of knock-over bits 16 are designed to be adjustable, however the plurality of knock-over bits 16 do not move when one of the plurality of corresponding needles 15 moves. Moreover, the gap 10 of the present invention is defined by the plurality of knock-over bits 16 of the two needle beds 11 and 12 that face each other. The distance of the gap 10 is equal to the space 101 (as shown in the figure) between two knock-over bits 16 which are facing each other. Referring to Figs. 3, 4, 5 and 6, each of the plurality of needles 15 comprises a butt 151. Each of the plurality of knock-over bits 16 comprises a control butt 161 disposed at a same side as each of the butts 151. Further, each of the plurality of knock-over bits 16 is respectively overlapped on one of the plurality of corresponding needles 15, and the butt 151 is disposed at one side of the needle 15 opposing to a needle bed base 17. The control butt 161 is disposed at one side of the plurality of knock-over bits 16 opposing to the needle bed base 17. Referring to Fig. 6, each of the plurality of needles 15 may define a needle extending line 152. The butt 151 on the needle 15 is positioned on the needle extending line 152. The control butts 161 corresponding to the needle 15 on one of the plurality of knock-over bits 16 is also positioned on the needle extending line 152. Furthermore, in order to ensure that the control butt 161 and the butt 151 are positioned on the same needle extending line 152, the length of each of the plurality of knock-over bits 16 is shorter than the total length of the plurality of needles 15.

[0016] Referring to Fig. 4 and Fig. 6, in an embodiment, each of the plurality of knock-over bits 16 comprises an extending section 162 provided with the control butt 161, a bending section 163 connected with the extending section 162, and a loop hanging section 164 connected with the bending section 163 as well as paralleled to a front edge of one needle 15. Further, the extending section 162 is overlapped above the needle 15. The bending section 163 allows the loop hanging section 164 and the extending section 162 are positioned on different extending lines, and allows the loop hanging section 164 to parallel with the needle 15 and hang a loop when the needle 15 moves. Moreover, each of the plurality of knock-over bits 16 also comprises a wire mounting hole for loosening loop 165 located on the loop hanging section 164, and at least one wire mounting hole for limiting position 166 located on the extending section 162. Referring to Figs. 5 and 6, in an embodiment, the plurality of knock-over bits 16 are implemented with two different thicknesses on the loop hanging section 164. Further, the thickness of the loop hanging section 164 of the knock-over bits 16 is able to be implemented with thicknesses smaller than the thickness of other parts of the knock-over bits 16, as shown in Fig. 6. Referring to Fig. 2 and Fig. 4, each of the needle beds 11 comprises a plurality of chutes 171 respectively formed on the needle bed base 17. Each of the plurality of knock-over bits 16 comprises a bottom 167 positioned at the loop hanging section 164 and disposed into the chute 171.

[0017] Referring to Figs. 2, 7 and 8, in another aspect, each of the cam systems 13(14) is respectively disposed to face one of needle beds 11(12). Each of the cam systems 13(14) comprises a needle cam 131 to provide the butts 151 being placed, and a knock-over bit cam 132 provides the control butts 161 being placed. The needle cam 131 and the knock-over bit cam 132 may be formed by at least one cam unit. The needle cam 131 comprises a convex and a valley which are continuous so that the butts 151 disposed therein make a knitting stroke towards the gap 10 when each of the cam systems 13(14) is operated. Moreover, in an embodiment, the knock-over bit cam 132 comprises a first guide section 134, a straight section 135 connected with the first guide section 134, and a second guide section 136 connected with the straight section 135. The first guide section 134 and the second guide section 136 are respectively tapered towards the straight section 135, and the size of the straight section 135 is constant. Further, the first guide section 134 and the second guide section 136 are designed to be tapered in order to actually guide the control butts 161 after the knock-over bit cam 132 moves. Furthermore, each of the knock-over bit cams 132 is respectively disposed at one side of each of the cam system 13(14) where faces the gap 10.

[0018] Based on the foregoing mentioned, the knock-over bit cam 132 of the present invention determines the position of each of the plurality of knock-over bits 16, so as to change the size of the gap 10. Unlike the needle cam 131, the knock-over bit cam 132 does not have the convex and the valley obviously. Most of guiding portions in the knock-over bit cam 132, which guides each of the plurality of knock-over bits 16, are straight. However, in the present invention, the knock-over bit cam 132 is controlled to define a displacement stroke 133. In the displacement stroke 133, the knock-over bit cam 132 makes one-dimensional motion relative to a cam base 137 and simultaneously drives each of the plurality of knock-over bits 16 to displace, so as to change the position of each of the plurality of knock-over bits 16. Thus, the size of the gap 10 is changed, and the foregoing-mentioned displacement of the knock-over bit cam 132 is shown in Fig. 2 and Fig. 3.

[0019] Based on this, each of the knock-over bit cams 132 of the present invention is also connected with a motion mechanism. The motion mechanism drives each of the knock-over bit cams 132 to make the displacement stroke 133 according to an accepted control signal. The generation of the control signal is set based on a programming. Thus, in the knitting process of the three-dimensional fabric 90, the thickness of the three-dimensional fabric 90 is changed, and the three-dimensional fabric 90 is even allowed to generate a structure with concave and convex outside the plane.
