Description

Technical Field

[0001] The invention relates to the technical field of sock machine manufacturing, and in particular to a sock transfer device with a turning function. Background Art

[0002] At present, for fully automatic sock manufacturing, the sock machine generally needs to have the functions of weaving, transferring, sewing, and turning socks from sock tube to sock;

[0003] Patent application number 200980108882.0 discloses a method and device for closing a tubular knitted object at its axial end at the end of the production cycle of a tubular knitted object on a circular knitting machine for socks, etc. During the transfer operation, the transfer needle needs to move upward from under the needle tongue close to the needle. Such a structure makes it difficult for the main transfer needle to move corresponding to the needle when the number of needles on the needle cylinder is large.

[0004] The patent with application number 202311042803.9 discloses a sock transfer device with the function of pushing, picking up and pressing, which includes a main transfer arm device and a secondary transfer arm device. When working, the flipping motor flips the flipping semicircular gear disk assembly to the position below the fixed semicircular gear disk assembly. At this time, the needle tip of the right main transfer needle is aligned and enters into the left main transfer needle on the fixed semicircular gear disk assembly, and then the coil of the other half of the sock on the right main transfer needle is pushed onto the left main transfer needle. However, with this flipping method, if the distance between the left main transfer needle and the right main transfer needle is close after flipping, although it is convenient for the transfer of the sock coil, the needle tips of the left main transfer needle and the right main transfer needle are prone to contact during the flipping process, which will reduce the service life of the transfer needle. If the distance between the left main transfer needle and the right main transfer needle is far after flipping, it will be unfavorable for the transfer of the sock coil. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a sock transfer device with a flipping function to solve the problem of the existing sock transfer device that the needle tips of the left main transfer needle and the right main transfer needle are prone to contact during the flipping process, which will reduce the service life of the transfer needle and cause poor sock coil transfer effect.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A sock transfer device with a flipping function, comprising a main transfer device, the main transfer device comprising a fixed bracket, a top sock barrel, a transfer cylinder base, a main drive assembly, a mounting base, a fixed semicircular toothed disc assembly and a flip semicircular toothed disc assembly, and an auxiliary drive assembly is arranged on the top sock barrel;

[0008] The fixed semicircular toothed disc assembly comprises a circular toothed disc arranged at the bottom end of the mounting base, a plurality of first needle grooves are opened on the left semicircle of the circular toothed disc, a left main transfer needle is installed inside the first needle groove through an elastic ring, and an oblique hole is opened on the right semicircle of the circular toothed disc;

[0010] The left main transfer needle is longer than the right main transfer needle. When the auxiliary drive assembly is extended, the left main transfer needle and the right main transfer needle form a standard circle. When the auxiliary drive assembly is contracted, the elastic ring causes the right main transfer needle and the left main transfer needle to be misaligned.

[0011] Preferably, the main drive assembly includes a first cylinder, a cylinder cover and an air joint mounted on a fixed bracket, the output end of the first cylinder is fixedly connected to a transfer cylinder base, and the lower surface of the transfer cylinder base is fixedly connected to a vertical rod corresponding to the push rod.

[0012] Preferably, the auxiliary drive assembly includes a second cylinder fixedly connected to the transfer cylinder base, and the output end of the second cylinder is fixedly connected to a long rod, the long rod passes through a circular gear disk and is fixedly connected to an arc-shaped needle withdrawal disk, the long rod is slidably connected to the circular gear disk, and the arc-shaped needle withdrawal disk is used to make multiple left main transfer needles rotate around one end close to the mounting base.

[0013] Preferably, a plurality of second needle grooves are formed on the outer surface of the arc-shaped needle withdrawal disk, and the left main transfer needle is located inside the second needle groove.

[0014] Preferably, an annular groove is formed on the outer surface of the circular toothed disc, and the elastic ring is made of rubber and is located inside the annular groove.

[0015] Preferably, the inner bottom ends of the left main transfer needle and the right main transfer needle are both provided with oblique grooves, and the top end of the left main transfer needle is provided with two positioning grooves.

[0016] Preferably, it also includes an auxiliary transfer device, which includes an auxiliary transfer needle disk, a mounting base, an inner steel ring, a transfer needle driving eyebrow, a guide rail mounting disk, a guide rail disk and multiple auxiliary transfer needles. The multiple auxiliary transfer needles are installed on the mounting base through the auxiliary transfer needle disk and the inner steel ring.

The bottom end of the guide assembly passes through the arc guide hole and the guide rail mounting disk and is fixedly connected to the transfer needle driving eyebrow. The transfer needle driving eyebrow is cooperatively connected with multiple auxiliary transfer needles. When the guide rail disk rotates, the guide assembly and the transfer needle driving eyebrow shrink inward and drive multiple auxiliary transfer needles to move out and retract needles.

[0017] Preferably, the auxiliary transfer needle is a thin sheet structure, comprising a needle guide portion and a loop undocking transfer portion of different thicknesses, a protrusion is provided on the side of the loop undocking transfer portion away from the needle guide portion, a through groove is provided on the outer side of the protrusion, and the thickness of the needle guide portion is less than the thickness of the loop undocking transfer portion.

[0018] Preferably, the number of the auxiliary transfer needle driving eyebrows is five, and the five auxiliary transfer needle driving eyebrows are interconnected to form a ring. A guide groove is provided on the lower surface of the auxiliary transfer needle driving eyebrow, and the protrusion is located inside the guide groove.

[0019] Preferably, the guide assembly includes an arc-shaped fixing plate, two mounting screws and two guide columns. A plurality of guide straight holes are opened on the guide rail mounting plate. The guide columns are fixedly connected to the transfer needle driving eyebrows and are located inside the arc-shaped guide holes and the guide straight holes. The mounting screws are fixedly connected to the guide columns.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] In the above scheme, when in use, the auxiliary transfer needle is extended, and the second cylinder is extended to drive the long rod and the arc-shaped needle withdrawal disk to move downward. The arc-shaped needle withdrawal disk can make the left main transfer needle slightly rotate around the needle seat during the movement. The left main transfer needle expands the elastic ring after rotation. At this time, the needle tips of the left main transfer needle and the right main transfer needle form a standard circle. Then the external driving device moves the main transfer device and the auxiliary transfer device downward, and under the guiding action of the auxiliary transfer needle, the sock machine needle is accurately guided into the left main transfer needle and the right main transfer needle.

[0022] The needle tip of the left main transfer needle is slightly contracted inwardly by the contraction force of the elastic ring. At this time, the semicircular diameters of the needle tips of the multiple left main transfer needles are smaller than the semicircular diameters of the needle tips of the multiple right main transfer needles. Then, the flipping motor is used to flip the flipping semicircular gear disk assembly to the position of the fixed semicircular gear disk assembly. At this time, the needle tip of the right main transfer needle on the flipping semicircular gear disk assembly is located outside the left main transfer needle on the fixed semicircular gear disk assembly. Then, the short needle withdrawal disk moves to push the other half of the coil of the sock on the right main transfer needle onto the left main transfer needle. Finally, the flipping semicircular gear disk assembly is reset by the reset spring to complete the transfer of the sock needle loop. Since the semicircular diameter of the needle tip of the left main transfer needle can be adjusted, the needle tip radius of the left main transfer needle is contracted before flipping. During the flipping process, the needle tips of the right main transfer needle and the left main transfer needle will not rub against each other. At the same time, the needle tips are better fitted after flipping, thereby improving the coil transfer effect of the sock. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The left main transfer needle 604 is longer than the right main transfer needle 706. When the auxiliary drive assembly 8 is extended, the left main transfer needle 604 and the right main transfer needle 706 form a standard circle. When the auxiliary drive assembly 8 is contracted, the elastic ring 603 causes the right main transfer needle 706 and the left main transfer needle 604 to be misaligned.

The first cylinder 401 can be a two-stage or three-stage cylinder to better turn the sock coil over.

[0051] like Figure 4 and Figure 5 As shown, in this embodiment, the auxiliary drive assembly 8 includes a second cylinder 801 fixedly connected to the transfer cylinder base 3, and the output end of the second cylinder 801 is fixedly connected to a long rod 802, the long rod 802 passes through the circular toothed disk 601 and is fixedly connected to an arc-shaped needle withdrawal disk 803, the long rod 802 is slidably connected to the circular toothed disk 601, the arc-shaped needle withdrawal disk 803 is used to make a plurality of left main transfer needles 604 rotate around one end close to the mounting base 5, and a plurality of second needle grooves are provided on the outer surface of the arc-shaped needle withdrawal disk 803, and the left main transfer needle 604 is located inside the second needle groove.

[0052] After the sock turning work is completed, the second cylinder 801 contracts to drive the long rod 802 and the arc-shaped needle withdrawal disk 803 to move upward. During the movement of the arc-shaped needle withdrawal disk 803, the contraction force of the elastic ring 603 causes the needle tip of the left main transfer needle 604 to slightly contract inward. At this time, the semicircular diameter of the needle tips of the multiple left main transfer needles 604 is smaller than the semicircular diameter of the needle tips of the multiple right main transfer needles 706.

[0053] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, an annular groove 606 is provided on the outer surface of the circular toothed disk 601 , and the elastic ring 603 is made of rubber and is located inside the annular groove 606 , so that the elastic ring 603 can better change the semicircular diameter of the needle tip of the left main transfer needle 604 .

A plurality of arc guide holes 17 are provided on the guide rail disk 15. A guide assembly 18 is provided inside two adjacent arc guide holes 17. The bottom end of the guide assembly 18 passes through the arc guide hole 17 and the guide rail mounting disk 14 and is fixedly connected to the transfer needle driving eyebrow 13. The transfer needle driving eyebrow 13 is cooperatively connected with the plurality of auxiliary transfer needles 16. When the guide rail disk 15 rotates, the guide assembly 18 and the transfer needle driving eyebrow 13 are retracted inwardly and drive the plurality of auxiliary transfer needles 16 to move the needles out and retract the needles.

[0056] When in use, the auxiliary transfer needle 16 is extended, and then the guide plate 15 is driven to rotate under the drive of the auxiliary transfer needle stroke cylinder, through the arc guide hole 17 on the guide plate 15, and under the action of the guide assembly 18 cooperating with the guide straight hole 1804, combined with the transfer needle driving eyebrow 13 to move outward, so that the auxiliary transfer needle 16 is retracted and withdraws from the crossing position of the sock machine knitting needles.

[0057] like Fig. 9 and Fig.12 As shown, in the present embodiment, the auxiliary transfer needle 16 is a thin sheet structure, and the auxiliary transfer needle 16 includes a needle guide portion 1601 and a loop undocking transfer portion 1602 of different thicknesses. A protrusion 1603 is provided on the side of the loop undocking transfer portion 1602 away from the needle guide portion 1601, and a through groove 1604 is provided on the outer side of the protrusion 1603. The thickness of the needle guide portion 1601 is less than the thickness of the loop undocking transfer portion 1602. In this way, under the guiding needle action of the auxiliary transfer needle 16, the sock machine needle is accurately guided into the left main transfer needle 604 and the right main transfer needle 706.

[0058] like Fig. 9 , Fig.10 and Fig.11 As shown, in the present embodiment, the number of auxiliary transfer needle driving eyebrows 13 is five, and the five auxiliary transfer needle driving eyebrows 13 are interconnected to form a ring. A guide groove 1301 is provided on the lower surface of the auxiliary transfer needle driving eyebrow 13, and the protrusion 1603 is located inside the guide groove 1301. The auxiliary transfer needle driving eyebrow 13 can make the auxiliary transfer needle 16 better retract or extend through the guide groove 1301.

[0059] like Fig. 9 and Fig.10 As shown, in this embodiment, the guide assembly 18 includes an arc-shaped fixing plate 1801, two mounting screws 1802 and two guide columns 1803. A plurality of guide straight holes 1804 are provided on the guide rail mounting plate 14. The guide column 1803 is fixedly connected to the transfer needle driving eyebrow 13 and is located inside the arc-shaped guide hole 17 and the guide straight hole 1804. The mounting screw 1802 is fixedly connected to the guide column 1803.

[0060] The technical solution provided by the present invention is that the main transfer device 111 and the auxiliary transfer device 112 are connected to an external driving device, and the main transfer device 111 and the auxiliary transfer device 112 can be rotated and moved on the same axis of the needle cylinder assembly of the hosiery machine through the external driving device. The specific structure is not described in detail here. When in use, the auxiliary transfer needle 16 is extended, and the second cylinder 801 is extended to drive the long rod 802 and the arc-shaped needle withdrawal disk 803 to move downward. The arc-shaped needle withdrawal disk 803 can make the left main transfer needle 604 rotate slightly around the needle seat during the movement. The left main transfer needle 604 expands elastically after rotation. Circle 603, at this time, the needle tips of the left main transfer needle 604 and the right main transfer needle 706 form a standard circle, and then the external driving device moves the main transfer device 111 and the auxiliary transfer device 112 downward, and under the guiding needle action of the auxiliary transfer needle 16, the sock machine needle is accurately guided into the left main transfer needle 604 and the right main transfer needle 706, and then the guide plate 15 is driven to rotate by the auxiliary transfer needle stroke cylinder, through the arc guide hole 17 on the guide plate 15, and under the action of the guide assembly 18 cooperating with the guide straight hole 1804, combined with the transfer needle driving eyebrow 13 to move outward, so that the auxiliary transfer needle 1 6 contracts and withdraws from the crossed position of the knitting needles of the sock machine. Then, after the sock turning work is completed, the second cylinder 801 contracts to drive the long rod 802 and the arc-shaped needle withdrawal disk 803 to move upward. During the movement of the arc-shaped needle withdrawal disk 803, the contraction force of the elastic ring 603 causes the needle tip of the left main transfer needle 604 to slightly contract inward. At this time, the semicircular diameter of the needle tips of the multiple left main transfer needles 604 is smaller than the semicircular diameter of the needle tips of the multiple right main transfer needles 706. Then the turning motor turns the turning semicircular toothed disk assembly 7 to the position of the fixed semicircular toothed disk assembly 6. At this time, the needle tip of the right main transfer needle 706 on the turning semicircular toothed disk assembly 7 is located at Fix the outer side of the left main transfer needle 604 on the semicircular toothed disk assembly 6, then move the short needle withdrawal disk 705 to push the other half of the coil of the sock on the right main transfer needle 706 onto the left main transfer needle 604, and finally reset the semicircular toothed disk assembly 7 by the reset spring 702 to complete the transfer of the sock needle loop. Since the semicircular diameter of the needle tip of the left main transfer needle 604 can be adjusted, the needle tip radius of the left main transfer needle 604 is contracted before flipping. During the flipping process, the needle tips of the right main transfer needle 706 and the left main transfer needle 604 will not rub against each other. At the same time, the needle tips will fit better after flipping, thereby improving the needle loop transfer effect of the sock.
