Description

Technical Field

[0001] The invention relates to the field of flat knitting machines, and in particular to a multifunctional electromagnetic needle selection method. Background Art

[0002] Computer glove knitting machine is a kind of flat knitting machine, and its basic structure is: front and rear needle beds are arranged between the left and right bases, movable knitting needles are arranged in the needle grooves of the needle beds, and cam bottom plates are arranged on the split front and rear heads, and the cam bottom plates move left and right with the random heads; because various cams are arranged on the cam bottom plates, the needles are selected, started and cleared through the interaction of the needle butts of the cams and knitting needles (combination needles), so as to complete various knitting functions.

[0003] The selection of knitting needles is carried out through a needle selection mechanism. The needle selection mechanism commonly used in existing glove machines is a needle selection roller, as shown in CN106521790A. By arranging a needle selection pin in the groove of the needle selection roller, the surface of the needle selection roller forms three contact surfaces of different heights corresponding to the high position (corresponding to normal knitting, also called full-mesh knitting), the middle position (corresponding to tuck knitting), and the low position (also called zero position, non-knitting position) commonly used in glove knitting. The needle selection bird piece interacts with the contact surfaces to achieve three-position knitting.

[0004] However, in this type of needle selection structure, once the needle selection pin is set on the needle selection drum, if the knitting style of the gloves needs to be changed, the machine needs to be stopped to remove the needle selection pin and then reinstall the needle selection pin according to the style.

[0005] There is also a method, such as that mentioned in CN207121685U, which adopts an electromagnetic needle selector to select needles. Paragraph 0058 of its specification discloses that "the needle selection head body 941 can swing left and right through the selection function of the coil 943 to meet the need of needle selection." However, this method can only select "knit or not knit", which is used to knit gloves that do not have complex styles, and it cannot select the three power positions of high, medium and low at the same time.

[0006] Therefore, the inventor conducted further research and developed a multifunctional electromagnetic needle selection method, which resulted in the present invention. Summary of the invention

[0007] The object of the present invention is to provide a multifunctional electromagnetic needle selection method, while achieving the flexibility and diversity of glove knitting.

[0008] In order to achieve the above object, the technical solution of the present invention is as follows:

[0009] A multifunctional electromagnetic needle selection method, which drives the needle selection bird piece to swing through a driving member and cooperates with the movement of the needle selector to realize the three-position knitting state of the knitting needle, and includes the following actions:

[0010] Select the high-position knitting action, lift several knitting stitches that need to participate in the high-position knitting to the high-position state through the needle selector bird piece, and the corresponding needle selector piece butt starts to work to support the needle selector bird piece, so that the needle butt of the corresponding knitting stitch is in the high-position state;

[0011] Select the action of mid-position knitting, lift several knitting stitches that need to participate in mid-position knitting to the mid-position state through the needle selection bird piece, select the corresponding needle device and start working to support the needle selection bird piece, so that the needle butt of the corresponding knitting stitch is in the mid-position state;

[0012] Select the zero position action, and the needle selector corresponding to the knitting stitches that do not participate in knitting will not work;

[0013] In the above action, the side of the needle selector piece adjacent to the butt of the needle selector piece includes three different positions, and all of them can contact with the butt of the needle selector piece, corresponding to the three states of the butt of the knitting stitch respectively.

[0014] In this concept, the needle selector, the needle selector, and the knitting needle (the lowest part of the knitting needle) are one-to-one corresponding and arranged horizontally on the needle bed; the needle selector is linked with the knitting needle, and the butt of the knitting needle can protrude from the needle bed, which is a common technical means in this field. The needle selector drives its butt to swing only between two positions. Therefore, if the three positions are to be selected, it is necessary to control the different positions of the needle selector to match the heel of the needle selector, so that the change in the relative position between the heel of the needle selector and the needle selector corresponds to the three positions when the gloves are knitted, thereby realizing the switching of the butt of the knitting needle in the high position, the middle position, and the low position; the needle selector and the knitting needle are set one-to-one, and the heel of the needle selector can also be controlled to move its position separately. Therefore, the above scheme can ensure the selection of high, middle, and low positions, and can also change the knitting style of the gloves without stopping the machine.

[0015] Furthermore, when the needle selection bird plate is driven by the same driving member, the needle selection bird plate is first driven to make the needle butt of the knitting stitch reach a high position, and the corresponding needle selector plate butt works to keep the needle butt in a high position; then the needle selection bird plate is driven to make the needle butt of the knitting stitch reach a middle position, and the corresponding needle selector plate butt works to keep the needle butt in a middle position.

[0016] Furthermore, when the needle selection bird piece is driven by different driving members, the butts of the knitting stitches that need to participate in high-position knitting are pushed to the high-position state, and the butts of the knitting stitches that need to participate in middle-position knitting are pushed to the middle-position state.

[0017] Furthermore, the side adjacent to the needle selector bird plate and the butt of the needle selector includes three different positions. The three different positions on the side of the needle selector bird plate are respectively a low-order position, a middle-order position, and a high-order position. When the needle selector bird plate is driven to make the butt of the knitting stitch reach the middle position, the needle selector works, and the butt of the needle selector is restricted by the high-order position of the needle selector bird plate and can only stay in the middle-order position.

[0018] Furthermore, the needle selector bird piece is driven to move or swing by the driving member, so that the needle selector plate heel contacts the low-order position, the middle-order position and the high-order position on the needle selector bird piece.

[0019] Furthermore, the drive of the needle selection bird piece by the drive member includes rotation drive, swing drive or linear drive.

[0020] Rotational drive refers to driving by means of a cam or the like; swing drive can refer to the method disclosed in the prior patent CN201045161Y; linear drive refers to pushing the needle selection bird piece when the driving member performs linear motion.

[0021] Furthermore, the driving member is a rotating member, and the outer ring of the rotating member is provided with two protrusions of different heights.

[0022] Three driving positions are formed by two protrusions and the outer ring edge of the rotating part itself, so that the needle selection bird piece can be switched between the three positions conveniently.

[0023] Furthermore, when the rotating part rotates, the contact point between the needle selector bird plate and the rotating part switches between the protrusion and the outer ring of the rotating part, and the auxiliary needle selector plate heel switches between the low-order position, the middle-order position and the high-order position of the needle selector bird plate.

[0024] Furthermore, the contact portion between the needle selector bird piece and the needle selector plate butt is a step-type structure, and the steps constitute the low-order position, the middle-order position and the high-order position of the needle selector bird piece.

[0025] Furthermore, the needle selector bird piece is provided with an axial hole, and the axial hole is used to pass the rotating shaft; the needle selector and the driving member are respectively located on both sides of the axial hole.

[0026] After adopting the above scheme, the present invention has the following advantages compared with the prior art:

[0027] The invention takes into account the advantages of the two needle selection schemes of the existing glove machine and avoids their disadvantages, that is, it ensures flexible knitting while having a multi-position knitting method. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Needle selection bird piece 1, contact part 11, rotating shaft 12,

[0035] Needle selector 2, needle selector butt 21, needle butt (of knitting stitches) 3,

[0036] Rotating member 4, protrusions (41, 42). DETAILED DESCRIPTION

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] In this embodiment, the contact portion 11 between the needle selector 1 and the needle selector 2 is a stepped structure, the driving member is a circular rotating member, and the driving member and the needle selector are located on both sides of the rotating shaft. Figure 1-3 As shown, it shows the states of the glove machine needle selection structure at zero position, high position and middle position respectively. The knitting needle (which is composed of different needle segments, also called combined needles, in this embodiment, mainly looks at the needle butt position of the knitting stitch of the lowest segment) is arranged in the needle groove, and its lower segment is linked with the needle selection bird piece 1. When the needle selection bird piece 1 swings with its rotating shaft 12 as the axis, the needle butt of the lower segment either protrudes from the needle groove or is retracted into the needle groove. Among them, both tuck knitting (middle position) and normal knitting (high position) require the needle butt to protrude from the needle groove:

[0039] Among them, when in zero position, the needle selector plate heel 21 of the needle selector 2 is at the lowest point of the step-type structure of the needle selector plate 1 (refer to Figure 5 ), at this time, the contact point between the needle selection bird piece 1 and the rotating member 4 is also at the lowest level (reference Figure 4 ), the knitting needle butt 3 is in the zero position on the needle bed, which means that this knitting needle does not participate in knitting and will not interact with the triangle on the triangle bottom plate.

[0040] When the knitting needle at a certain position in the needle groove is required to participate in normal knitting, the highest protrusion 41 of the rotating member 4 moves the needle selector bird plate 1 through the rotation of the rotating member 4, and the needle selector plate heel 21 swings to support the needle selector bird plate 1 at the high-order position of the contact part 11, such as Figure 2 As shown, at this time, the needle butt 3 of the knitting needle completely protrudes from the needle groove, and can run along the normal knitting track formed by the triangular bottom plate to perform normal knitting work.

[0041] When the knitting needle at a certain position in the needle groove is required to participate in the tuck knitting, the second highest protrusion 42 of the rotating member 4 also rotates to move the needle selector bird 1, and the needle selector plate heel 21 swings. At this time, since the needle selector plate heel is blocked by the high-order position of the contact part 11, it can only stay in the middle-order position of the needle selector bird 1 on the contact part 11, such as Figure 3 As shown, at this time, the needle butt 3 half protrudes from the needle groove, and can run along the tuck knitting track formed by the triangular bottom plate to perform tuck knitting work.

[0042] Taking a knitting needle as an example, the various working states are as follows:

[0043] If it is determined that the desired style does not require the needle in this knitting row to participate in the knitting work, the needle selector butt will not move, so that the needle butt is in the zero position, that is, Figure 1 state.

[0044] If the knitting needle of this knitting row needs to participate in normal knitting (full mesh), the rotating part rotates, and the heel of the needle selector swings, so that the needle butt is in a high position, that is, Figure 2 state.

[0045] If the knitting needle of this knitting row needs to participate in the tuck knitting, the rotating part rotates, and the heel of the needle selector swings, so that the needle butt is in the middle position, that is, Figure 2 state.

[0046] If taking a row of knitting needles as an example, within one rotation cycle of the rotating part, the above method can be used to first select the high-position knitting needle from the zero position (that is, the corresponding needle selector works to make the knitting needle butt at a high position), and then select the middle-position knitting needle from the zero position. When the middle-position knitting needle is selected for the second time, its needle selector butt will be blocked by the high-order position of the needle selector piece, so it will stay in the middle-order position of the needle selector piece, thus forming a middle-position knitting needle.

[0047] The needle selection bird piece will be reset, which is a common technical means in this field and will not be described in detail here.

[0048] The above is only a specific embodiment of the present invention. The active or passive movement of the needle selector bird piece and the change of the working position of the needle selector are all within the inventive concept of this case. At the same time, all words such as "up, down, left, right, middle" involved in the present invention are for reference only and are not absolutely limited. Any non-substantial changes made using the present invention shall be deemed as an infringement of the protection scope of the present invention.
