Description

Technical Field

[0001] The present invention relates to a fabric picking device, and more particularly to a non-needle-aligning fabric picking device. Background Art

[0002] For the picking of fabrics, especially for the picking of socks on an integrated sock knitting machine, it is a key core step in sock manufacturing. The existing picking of fabric socks on an integrated sock knitting machine is completed by the cooperation of picking needles and knitting needles for needle alignment. The core structure of the picking needle and the knitting needle is the needle groove. The cooperation between the picking needle and the knitting needle is completed through the needle groove. In terms of appearance, the knitting needle and the picking needle must penetrate the coil holes on the same coil, which leads to great manufacturing difficulty and installation difficulty for the knitting needle and the picking needle. Especially when knitting socks with different needle counts, after the needle cylinder is replaced, the matching picking needle plate needs to be replaced synchronously, resulting in technical problems such as long replacement time and high accessory cost.

[0003] The existing Chinese invention patent application number: 201920619854.6, patent name: A transfer needle for transferring fabrics, discloses a transfer needle for transferring fabrics, including: a transfer needle body; a transfer part, the transfer part extends downward from the head of the transfer needle body offsetting the axis of the transfer needle body, and the transfer part is arc-shaped. Although this kind of patent does not have a needle groove structure, it still adopts the technical solution of smoothly transferring the fabric coil to the transfer needle by the cooperation of the transfer needle and the knitting needle, and it does not have a technical hint or solution for non-needle alignment cooperation. How to reduce the manufacturing difficulty and technical requirements of the picking needle and increase the efficiency of sock picking is the research object of those skilled in the art. Summary of the Invention

[0004] The present invention provides a non-needle-aligning fabric picking device without needle groove cooperation between the picking needle and the knitting needle.

[0005] A non-needle-aligning fabric picking device includes picking needles and knitting needles installed on a knitting machine, where the knitting machine mainly refers to a sock knitting machine. The knitting needles cooperate with the first loops on the fabric. The first loops can be any loops on the fabric, preferably the last loops on the fabric. The picking needles cooperate with the second loops on the fabric. The first loops and the second loops are loops at two different positions. Since this device uses the picking needles and the knitting needles to respectively and correspondingly insert different loops on the fabric or the toe of the sock, avoiding the needle groove needle-aligning structure in the traditional structure, the picking efficiency of the sock or the fabric is greatly improved. This non-needle-aligning fabric picking device solves the problem that in the traditional sock knitting machine, due to the need to knit socks with different needle counts, it is necessary to correspondingly replace the needle cylinders with different needle counts. When the needle cylinder is replaced, the fabric picking device, transfer needles, etc. corresponding to the needle cylinder in the prior art all need to be replaced accordingly. However, in the present invention, only the same non-needle-aligning fabric picking device is needed when knitting socks with different needle counts and corresponding needle cylinders with different needle counts, greatly reducing the accessory manufacturing cost and the accessory replacement time.

[0006] The picking needles include a first needle tip and a second needle tip. The first needle tip and the second needle tip jointly cooperate with a loop hole on the fabric, or the first needle tip and the second needle tip respectively cooperate with a loop hole on the fabric. The picking needles adopt a two-needle-tip structure to jointly cooperate with a loop hole or respectively cooperate with a loop hole to achieve the technical effect of double-needle-tip hole locking, preventing problems such as missed stitches and loop dropout caused by the loosening of the loop hole.

[0007] The picking needles are of a single-needle-tip structure and are arranged in sequence. One picking needle tip cooperates with the first loop hole on the second loop, and the other picking needle tip cooperates with the second loop hole on the second loop. This technical solution adopts picking needles with single needle tips arranged in sequence, with one needle tip cooperating with the first loop hole and the other needle tip cooperating with the second loop hole. Here, the first loop hole and the second loop hole are two adjacent main loop holes and sub-loop holes, so that the two loops form a loop combination to prevent problems such as missed stitches and loop dropout.

[0008] The first needle tip and the second needle tip have different extending lengths. The first needle tip cooperates with the third loop hole on the second loop; the second needle tip cooperates with the fourth loop hole on the third loop. The picking needles with this structure adopt a two-needle-tip structure, with the front and back respectively cooperating with a loop hole to achieve the technical effect of front and back double-needle-tip hole locking, further preventing problems such as missed stitches and loop dropout caused by the loosening of the loop hole.

[0009] The described pick-up needles are installed on the pick-up transfer device of a hosiery machine. The pick-up transfer device includes an upper pick-up transfer device and a lower pick-up transfer device. The upper pick-up transfer device includes a main transfer disc. The pick-up needles are installed in the needle slots of the main transfer disc, and the radial movement of the pick-up needles is controlled by an upper control device. The lower pick-up transfer device includes a secondary transfer disc. The secondary pick-up needles are installed in the needle slots of the secondary transfer disc, and the radial movement of the secondary pick-up needles is controlled by a lower control device. The upper control device and the lower control device can adopt control devices in the prior art to control the forward and backward movement of the pick-up needles. Due to the installation of the pick-up needles and the cooperation with the coil structure, this pick-up transfer device can adapt to the picking of socks with different needle counts and can also adapt to different needle count cylinders, avoiding the technical drawbacks of replacing the pick-up transfer device in the traditional technology when dealing with different cylinders.

[0010] The described pick-up needles are paired with secondary pick-up needles. The secondary pick-up needles include a third tip and a fourth tip. The third tip and the fourth tip jointly cooperate with a coil hole on the fabric, or the third tip and the fourth tip respectively cooperate with a coil hole on the fabric. The pick-up needles cooperate with the upper and lower two needles of the secondary pick-up needles to achieve the technical purpose of clamping and picking up the fabric or socks up and down.

[0011] The described secondary pick-up needles include two juxtaposed tips. The two tips respectively cooperate with the first coil hole on the second coil and the second coil hole on the second coil. Here, the first coil hole and the second coil hole are two adjacent main coil holes and secondary coil holes. In this way, the two coils form a coil combination to prevent problems such as missed stitches and loop dropout, and further achieve the technical purpose of the mutual cooperation performance of the pick-up needles to achieve up and down clamping and picking up.

[0012] The lengths of the protrusions of the described third tip and fourth tip are different. The third tip cooperates with the third coil hole on the second coil; the described fourth tip cooperates with the fourth coil hole on the third coil. Further achieve the technical purpose of the mutual cooperation performance of the third tip and the fourth tip to achieve up and down clamping and picking up.

[0013] The number of the described pick-up needles is between 1.1 and 3 times the number of knitting needles. When the pick-up needles cooperate with socks or fabrics knitted with different cylinder needle counts, the socks or fabrics can be picked up by a method with more coil hole numbers, achieving the technical purpose of preventing thread dropout and missed stitches.

[0014] The number of the described secondary pick-up needles is between 1.1 and 3 times the number of knitting needles. When matching the pick-up needles to pick up socks or fabrics knitted with different cylinder needle counts, the socks or fabrics can be picked up by a method with more coil hole numbers, achieving the technical purpose of preventing thread dropout and missed stitches.

[0015] The pick-up needles are coupled with a first pair of pick-up needles, which are connected to an elastic member. The elastic member is generally a spring, which facilitates the lower control device to generate a buffering force when pushing the first pair of pick-up needles. At the same time, the spring force generated during the process of picking up the fabric in conjunction with the pick-up needles achieves the technical purpose of continuous clamping and locking.

[0016] The first pair of pickup needles are divided into two types: one corresponding to the knitting needles and the other not corresponding to the knitting needles. The non-corresponding first pair of pickup needles pass over the knitting needles to support the fabric. The first pair of pickup needles corresponding to the knitting needles are used to peel the coils or fabric off the knitting needles, while the first pair of pickup needles not corresponding to the knitting needles have the technical purpose of supporting the coils or fabric to prevent the coils or fabric from falling off the pickup needles.

[0017] The pick-up needles comprise a first pick-up needle and a second pick-up needle, each independently controlled by an upper control device, while the first pick-up needle is controlled by another upper control device. The first and second pick-up needles work together to engage one or two stitch holes in the fabric. Driven by the two upper control devices, the first and second pick-up needles can adjust their relative positions, thereby achieving stretching and clamping performance for one or both stitch holes, further improving the pick-up needles' adaptability to socks and needle cylinders with varying needle counts.

[0018] The picking needle comprises two needle tips, and the distance between the two needle tips is equal to or greater than the distance between two adjacent coil holes on the fabric, so as to achieve locking performance for the two coil holes.

[0019] The present invention adopts a picking needle and a knitting needle to respectively plug into different coils on the fabric or the sock toe, avoiding the needle groove matching needle structure in the traditional structure, greatly improving the picking efficiency of the socks or fabrics, and at the same time, it can be achieved that when knitting socks with different needle numbers and corresponding needle cylinders with different needle numbers, only the same non-matching needle type fabric picking device is needed, which greatly reduces the manufacturing cost of accessories and the time of accessory replacement.

[0045] See Figure 1-20 As shown, a non-needle-aligning fabric pick-up device includes a pick-up needle and a knitting needle 3 installed on a knitting machine. The knitting needle 3 cooperates with a first coil 101 on a fabric 90, and the pick-up needle cooperates with a second coil on the fabric. The first coil and the second coil are coils at two different positions. Four pick-up needles are non-exhaustively listed in the present invention, namely pick-up needle 7, pick-up needle 71, pick-up needle 72, and pick-up needle 73. Of course, pick-up needles with improved shapes based on the concept of the present invention are within the protection scope of the present invention. The pick-up needle 72 is a pick-up needle with one needle tip; the pick-up needle 73 is a pick-up needle with two horizontal needle tips; the pick-up needle 7 is a pick-up needle with front and rear needle tips, and the pick-up needle 71 is a pick-up needle with a needle hook. The specific functions of these pick-up needles are specifically shown in the following embodiments.

The coil 101 is the coil of the last round of a sock or fabric, and the coils inside are coil 102, coil 103, and coil 104 in sequence.

[0046] Example 1 As Figure 2 As shown, the pick-up needle 7 includes a first needle tip 701 and a second needle tip 702. The first needle tip 701 and the second needle tip 702 jointly cooperate with a coil hole on the fabric 90, or the first needle tip 701 and the second needle tip 702 respectively cooperate with a coil hole on the fabric 90. The pick-up needle includes two needle tips, and the distance between the two needle tips is equal to or greater than the distance between two adjacent coil holes on the fabric, that is, H1 is greater than H2, and the locking performance of the coil is achieved through different distances.

[0047] Example 2 As Figure 4The shown picking needle 72 includes a needle tip 705, and another picking needle 72 includes a needle tip 706. The needle tip 705 cooperates with a first coil hole 1021 on the second coil 102; the needle tip 706 cooperates with a second coil hole 1022 on the second coil 102, achieving the technical purpose of piercing and locking the coil under the same coil.

[0048] Embodiment 3 is as Figure 5 The shown picking needle 73 includes two needle tips. The two needle tips jointly pierce a coil hole on a coil to achieve the purpose of double-needle locking.

[0049] Embodiment 4 is as Figure 6 , as shown in Fig. 7, the first needle tip 701 and the second needle tip 702 extend by different lengths to form front and rear needle tips. The first needle tip 701 cooperates with a third coil hole 1023 on the second coil 102; the second needle tip 702 cooperates with a fourth coil hole 1031 on the third coil 103. By simultaneously piercing two different coil holes on two different coils with two needle tips, the purposes of double-needle piercing and locking are achieved.

The upper picking and transferring device 201 includes a main transfer disk 8. The picking needle 7 is installed in the needle groove of the main transfer disk 8. The radial movement of the picking needle 7 is controlled by an upper control device 9. The upper control device 9 can adopt an existing control device, mainly a front and rear driving device; the lower picking and transferring device 202 includes a sub-transfer disk 11. The sub-picking needle 10 is installed in the needle groove of the sub-transfer disk 11. The radial movement of the sub-picking needle 10 is controlled by a lower control device 12. The lower control device 12 can adopt an existing control device, mainly a front and rear driving device. The picking and transferring device 2 has the ability of up and down lifting.

[0051] Embodiment 6 is as Figure 7 , as shown in Figs. 8, 9, 10, and 12, as a structural preference, the picking needle is cooperated with a sub-picking needle 10. The sub-picking needle 10 includes a third needle tip 1055 and a fourth needle tip 1056. The third needle tip 1055 and the fourth needle tip 1056 jointly cooperate with a coil hole on the fabric 90, or the third needle tip 1055 and the fourth needle tip 1056 respectively cooperate with a coil hole on the fabric 90. As Figure 23The lengths of protrusion of the third needle tip 1055 and the fourth needle tip 1056 shown are different. The third needle tip 1055 cooperates with the third coil hole 1023 on the second coil 102; the fourth needle tip 1056 cooperates with the fourth coil hole 1031 on the third coil 103, so as to achieve the technical purpose that the picking needle 7 and the auxiliary picking needle 10 jointly pick up the fabric. The picking process of this embodiment is as follows: the transfer disk 8 moves downward, the picking needle 7 cooperates with one or two coil holes on the fabric 90, and then the sock cylinder 6 is pushed up to push up the sock or the fabric 90, and the sock or the fabric 90 is separated from the knitting needle 3. The auxiliary transfer disk 11 moves downward, and the auxiliary picking needle 10 cooperates with the picking needle 7 to lock the sock or the fabric 90 up and down to achieve the technical purpose of picking up the sock or the fabric 90. Alternatively, the sock or the fabric 90 on the picking needle 7 can be moved to the auxiliary picking needle 10 by the upper retaining ring device 13, and the auxiliary picking needle 10 picks up the sock or the fabric 90.
