Description

Technical Field

[0001] The present invention relates to the technical field of sock knitting machines. More specifically, it relates to a sock conveyor for an integrated knitting, sewing, and turning sock knitting machine, and also relates to an integrated knitting, sewing, and turning sock knitting machine. Background Art

[0002] Currently, the more advanced sock knitting machines on the market usually adopt an integrated structure of sock knitting, sock turning, and sock sewing, and can be assembled jointly with equipment to form an automated production of socks. First, the sock knitting device weaves raw materials into a tubular sock tube; then, through the picking component on the sock knitting machine, the sock tube knitted by the sock knitting machine is transferred to the sock turning device, and the sock tube is sucked into the sock turning cylinder by negative pressure. The sock turning lifting cylinder extends from the inside of the sock turning cylinder to turn the sock tube; then the sock sewing component sews and processes the sock to obtain a complete sock.

[0003] This type of sock knitting machine can generally be applied to the production of shorter socks. However, for long socks, especially those exceeding the picking stroke of the picking component (generally 50 cm), there are relatively large problems. When the long sock is transferred from the sock knitting device to the sock turning device, the end of the long sock cannot be completely removed from the sock knitting device, and it is very difficult to smoothly feed it into the sock turning device, resulting in the inability of the sock knitting machine to continue production and affecting production efficiency.

[0004] In the prior art, the Chinese invention patent application with the publication number CN110144672A discloses a sock sewing machine, including an upper component, a lower component, a sewing component, and a picking component. The upper component and the lower component are respectively arranged at the upper and lower ends of the sewing component, and the picking component is arranged at the side of the sewing component. The lower component includes a sock suction cylinder and a sock turning lifting cylinder sleeved inside the sock suction cylinder; the sock turning lifting cylinder is connected to a negative pressure air source and can extend in the vertical axial direction towards the upper component; a lower component moving device for driving the lower component to reciprocate in an inclined direction is arranged outside the sock suction cylinder. This solution can increase the distance between the sock suction cylinder and the picking component by setting the sock suction cylinder as a movable structure and enabling it to reciprocate within the stroke in the inclined direction, so as to improve the applicability to long socks. However, the stroke distance of the sock suction cylinder is limited, and it is still not applicable to socks exceeding a certain length, and the above problems cannot be avoided; moreover, its structure is complex, and it is necessary to significantly change the structure of the traditional integrated sock knitting machine, making it difficult to be applied to the technical improvement of the traditional integrated sock knitting machine.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Invention

Detailed implementation manners

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1

[0039] This embodiment discloses a reciprocating sock conveyor for a hosiery machine, as Figure 1 shown. The sock conveyor 5 is installed on an integrated knitting, sewing, turning and knitting sock machine to cooperate with the production work of the sock machine;

[0040] The integrated knitting, sewing, turning and knitting sock machine includes components such as a hosiery machine 1, a sock sewing machine 2, and a picking component 3. Other structures of the sock machine will not be elaborated here. The picking component 3 can reciprocate between the hosiery machine 1 and the sock sewing machine 2, pick up one end of the sock in the cylinder assembly 101 of the sock sewing machine 2, and transfer it to the sewing tooth disc 202 of the sock sewing machine 2. The sock after being picked up forms a sock feeding path 4 between the cylinder assembly 101 of the hosiery machine 1 and the sewing tooth disc 202 of the sock sewing machine 2. The two ends of the sock can be supported at the position of the sock feeding path 4 to form a nearly straight path.

[0041] The sock conveyor 5 is installed between the sock knitting machine 1 and the sock sewing machine 2, corresponding to one side of the sock feeding path 4. Specifically, it includes a moving component 9, a clamping component 7, and a driving component 8 supported by a bracket 6, and is integrally installed on the frame of the sock machine. Among them, the clamping component 7 is driven by the moving component 9 and can move between a position close to and a position far from the sock feeding path 4. When in the close position, the components of the clamping component 7 are relatively close to the sock feeding path 4, and the clamping component 7 can clamp the socks in the sock feeding path 4.

[0042] The driving component 8 can be linked with the clamping component 7 and drive the clamping component 7 to move, forming ways such as moving and pulling, winding, roller conveying, etc., to pull the clamped socks out of the sock knitting machine 1, so that the socks can hang in the direction of the sock suction cylinder 201, facilitating the sock suction cylinder 201 to smoothly suck in the socks. When the clamping component 7 is in a position far from the sock feeding path 4, the clamping component 7 can move away from the vicinity of the sock feeding path 4 to avoid interference in the actions between mechanisms and allow the picking component 3 to move.

[0043] As Figure 2 、 3 shown, the clamping component 7 includes a clamping seat 71, a clamping piece 72, and a power component 75. Among them, the clamping seat 71 serves as the basic support of the clamping component 7 and is installed on the moving component 9; the clamping piece 72 is installed on the clamping seat 71 and can perform a clamping action under the drive of the power component 75, and the clamping piece 72 can adopt various forms. For example, a clamping block connected by means of hinging or sliding, or a structure such as an eccentric wheel structure that can achieve a clamping action.

[0044] In order for the socks to enter and exit the clamping piece 72, the clamping piece 72 is supported at one end, and the other end forms an openable and closable clamping mouth 73; in the state where the clamping mouth 73 is open, the socks at the sock feeding path 4 can enter the clamping piece 72 from the clamping mouth 73, and after the clamping mouth 73 is closed, the clamping piece 72 can clamp the socks. During the process of transporting the socks, adopting a clamping structure can improve the stability of sock transportation.

[0045] As Figure 4 shown, the clamping piece 72 includes a clamping piece one 721 and a clamping piece two 722, both of which are horizontal rods. One end of the clamping piece one 721 is installed on the clamping seat 71 for support, and one end of the clamping piece two 722 is installed on the movable block 74 and is connected to the clamping seat 71 through the movable block 74 to achieve an indirect connection with the clamping seat 71; and the movable block 74 can reciprocate on the clamping seat 71 and has a certain movement stroke relative to the clamping piece one 721, so as to form an openable and closable clamping mouth 73 between the clamping piece one 721 and the clamping piece two 722, capable of clamping the socks.

[0046] The movable block 74 is in an inverted L shape. The second clamping member 722 is installed on the horizontal end 741 of the movable block 74. A sliding groove 711 is formed in the clamping seat 71. The vertical end 742 of the movable block 74 is slidably connected to the sliding groove 711. A cover plate 712 is covered at the opening of the sliding groove 711 for limiting. A sliding connection structure is formed between the movable block 74 and the clamping seat 71, and reciprocating sliding is realized by driving of a power member 75. The power member 75 includes a first cylinder 751 and a first elastic member 752. The fixed end of the first cylinder 751 is installed on the clamping seat 71, and the output end is connected to the movable block 74, which can drive the movable block 74 to slide away from the first clamping member 721 during operation. The first elastic member 752 can be a tension spring, with both ends respectively connected to the lower side of the clamping seat 71 and the horizontal end 741 of the movable block 74, and is hooked through a notch 771 on the horizontal end 741, and elastically acts on the movable block 74, which can elastically drive the movable block 74 to approach the first clamping member 721 within the moving stroke of the second clamping member 722. The power member 75 can also adopt a structure with bidirectional active expansion and contraction, and the first elastic member 752 can be cancelled.

[0047] When the first cylinder 751 works, the internal pressure in the first cylinder 751 increases, overcoming the elastic force of the first elastic member 752, pushing the movable block 74 to slide upward, and the second clamping member 722 moves away from the first clamping member 721, and the clamping opening 73 opens; after the first cylinder 751 is depressurized, the internal pressure in the first cylinder 751 decreases, and the movable block 74 descends under the action of the first elastic member 752 and its own weight, and the second clamping member 722 approaches the first clamping member 721, and the clamping opening 73 closes.

[0048] As Figure 4 shown, the driving assembly 8 can drive the clamping member 72 in a rotational conveying manner. One ends of the first clamping member 721 and the second clamping member 722 are respectively rotatably connected to the clamping seat 71 and the movable block 74, and are supported by bearings 811 to maintain smooth rotation, and the other ends are suspended ends 724.

[0049] The driving assembly 8 includes a rotary driver. The rotary driver has an output end that can actively rotate. The main body of the rotary driver is installed on the clamping seat 71. The output end of the rotary driver is transmitted to the first clamping member 721 through a gear set, so as to drive the first clamping member 721 to rotate. The rotary driver can specifically adopt a driving motor 81 or a pneumatic rotary tool and other tools that can rotate and drive.

[0050] When clamping, the sides of the first clamping member 721 and the second clamping member 722 that approach each other clamp the sock. The rotary drive operates, and the first clamping member 721 rotates. Through friction, the sock can be conveyed, so that the end of the sock is moved out from the middle of the sock knitting machine 1. By adopting the rotary conveying method, the conveying length of the sock is not limited by the spatial position, which can better adapt to the production of socks of different lengths, and occupies less space of the sock machine, which is beneficial to actual production and use. Anti-slip patterns can be processed on the outer peripheries of the first clamping member 721 and the second clamping member 722 to increase the friction force and avoid slipping.

[0051] Taking the drive motor as an example, the drive motor 81 can also be installed on the movable block 74, and its output end is connected to the second clamping member 722 for transmission to realize the rotary conveying of the sock. Or, the drive motor 81 can also drive the first clamping member 721 and the second clamping member 722 to rotate simultaneously. Linkage can be achieved through a belt or other means, and the rotation directions of the first clamping member 721 and the second clamping member 722 are kept opposite, which can also drive the clamping member 72 to rotate. When the first clamping member 721 and the second clamping member 722 both rotate simultaneously, the rotational speed needs to be adjusted adaptively to keep the conveying speeds on both sides of the sock consistent.

[0052] Since the first clamping member 721 and the second clamping member 722 need to convey the sock during rotation and are driven by friction; mutually adapted clamping portions 723 are respectively arranged on the first clamping member 721 and the second clamping member 722, and the clamping portions 723 are all in the shape of a rotating body.

[0053] After the first clamping member 721 and the second clamping member 722 approach each other, the clamping portions 723 on the first clamping member 721 and the second clamping member 722 can approach each other to stably clamp the sock. Moreover, the clamping portions 723 are all in the shape of a rotating body. During rotation, the outer peripheral contour can be kept stable, and the first clamping member 721 and the second clamping member 722 always maintain the clamping state, so that the sock can be stably conveyed.

[0054] For example, the middle main body positions of the first clamping member 721 and the second clamping member 722 can adopt a cylindrical structure, which is the clamping portion 723. Or, the clamping portions 723 of the first clamping member 721 and the second clamping member 722 can also adopt a structure of bead-shaped protrusions, which can also realize clamping and conveying. Or, the clamping portions 723 on the first clamping member 721 and the second clamping member 722 can also adopt a gear-shaped meshing structure, or a structure with one being cylindrical and the other being spherical bead-shaped protrusions can all realize the actions of clamping and rotary conveying.

[0055] In order to facilitate the sock to enter the clamping opening 73, the suspended ends 724 of the first clamping member 721 and the second clamping member 722 can be set in a conical or ball head shape, so that the sock can enter the clamping opening 73 more smoothly.

[0056] To avoid slippage between the first clamping member 721 and the second clamping member 722 and the sock to be clamped, anti-slip patterns can be formed at the clamping portions 723 of the first clamping member 721 and the second clamping member 722. By means of the anti-slip patterns, the friction with the sock is increased to maintain a stable conveying effect. The anti-slip patterns are surface concavo-convex structures. For example, the anti-slip patterns can be rough surfaces formed by grinding or extrusion; or, the anti-slip patterns can also be convex teeth and depressions machined on the first clamping member 721 and the second clamping member 722.

[0057] Anti-slip layers can also be formed on the outer peripheries of the first clamping member 721 and the second clamping member 722 to replace the anti-slip patterns; the anti-slip layers can be anti-slip sleeves supported by rubber materials or anti-slip coatings formed by coating with polymer materials, both of which can achieve the anti-slip effect.

[0058] The moving assembly 9 includes a lateral movement mechanism 91 and a lifting mechanism 92. Among them, the lateral movement mechanism 91 can drive lateral movement, and the lifting mechanism 92 can drive lifting in the up-and-down direction. The lifting mechanism 92 and the lateral movement mechanism 91 cooperate with each other, so as to drive the clamping member 72 to move in two dimensions, namely, laterally and vertically.

[0059] The lateral movement mechanism 91 can be installed on the bracket first, and then the lifting mechanism 92 can be installed on the lateral movement mechanism 91, so that the lifting mechanism 92 can drive the clamping member 72 to lift in the vertical direction, and the lateral movement mechanism 91 can drive the lifting mechanism 92 and the clamping member 72 to move laterally together. Or the installation positions of the two can also be adjusted. The lateral movement mechanism 91 can drive the clamping assembly 7 to move in the lateral direction, and the lifting mechanism 92 can drive the lateral movement mechanism 91 and the clamping assembly 7 to lift in the vertical direction together.

[0060] Specifically, the lateral movement mechanism 91 includes a lateral movement support member 911, a lateral movement member 912, a first guide sliding member 913 and a second cylinder 914; the lateral movement support member 911 is fixedly connected to the bracket 6 to form an integral structure. The first guide sliding member 913 is installed on the lateral movement support member 911 in a horizontal direction and is substantially perpendicular to the sock feeding path 4. The lateral movement member 912 is slidably connected to the lateral movement support member 911 through the first guide sliding member 913 and can achieve reciprocating sliding; the second cylinder 914 is installed on the lateral movement support member 911, and its driving end is connected to the lateral movement member 912 and can drive and push the lateral movement member 912.

[0061] The second cylinder 914 can adopt a double-directional telescopic mechanism, so as to directly drive the lateral movement member 912 to reciprocate; or, the second cylinder 914 only adopts a pneumatic pushing structure and cooperates with a second elastic member 915 for action. The second elastic member 915 can be a tension spring, and its two ends are respectively connected between the lateral movement support member 911 and the lateral movement member 912. Through elasticity, the output end of the second cylinder 914 can be driven to return to form reciprocating drive.

[0062] The lifting mechanism 92 includes a lifting support 921, a lifting member 922, a second guiding and sliding member 923, and a third cylinder 924; the lifting support 921 is fixedly installed on the transverse moving member 912, so as to realize the linkage with the transverse moving mechanism 91. The second guiding and sliding member 923 is installed vertically on the lifting support 921. The lifting member 922 is slidably connected to the lifting support 921 through the second guiding and sliding member 923, and can realize reciprocating lifting and sliding; the third cylinder 924 is installed on the lifting support 921, and its driving end is connected to the lifting member 922, and the lifting member 922 can be driven up and down by the cylinder. During the working process of the third cylinder 924, the cylinder is pressurized, and the driving end rising can drive the lifting member 922 to move upward. When the cylinder is depressurized, the driving end automatically descends and retracts under the action of itself and the clamping assembly 7, so as to realize the two-way lifting action.

[0063] When the lifting mechanism 92 drives the clamping member 72 to move to the uppermost end, the transverse moving mechanism 91 drives the lifting mechanism 92 and the clamping member 72 to move to the foremost end. At this time, the clamping assembly 7 is in a position close to the sock feeding path 4, and the clamping opening 73 of the clamping member 72 is at the sock feeding path 4, and the sock enters the clamping opening 73, and the clamping member 72 can clamp the sock. When the lifting mechanism 92 drives the clamping member 72 to move to the lowermost end, the transverse moving mechanism 91 drives the lifting mechanism 92 and the clamping member 72 to move to the rearmost end. At this time, the clamping assembly 7 is in a position away from the sock feeding path 4, and the clamping assembly 7 leaves between the sock knitting machine 1 and the sock sewing machine 2, so as to avoid interfering with the picking-up assembly 3 and other components of the sock machine.

[0064] This embodiment also discloses an integrated sock knitting, sewing, turning and knitting machine, which includes a sock knitting machine 1, a sock sewing machine 2, a picking-up assembly 3 and the above-mentioned sock conveyor 5; the sock conveyor 5 is installed between the sock knitting machine 1 and the sock sewing machine 2, corresponding to one side of the sock feeding path 4, and can cooperate with the picking-up assembly 3 to pull the clamped sock out of the sock knitting machine 1, so that the sock can hang in the direction of the sock sucking cylinder 201, so that the sock sucking cylinder 201 can smoothly suck the sock.

[0065] Embodiment Two

[0066] This embodiment discloses a reciprocating sock conveyor of a sock knitting machine. On the basis of Embodiment One, refer to Figure 5 、 6 for description; compared with Embodiment One, the structure of the clamping assembly 7 is redesigned, and the clamping member one 721 and the clamping member two 722 can also be opened and closed by means of rotational connection.

[0067] Such as Figure 5As shown, in the clamping assembly 7, the middle section of the movable block 74 is rotatably connected to the clamping seat 71, and the axis of the rotating shaft is parallel to both the first clamping member 721 and the second clamping member 722. One end of the second clamping frame is installed on the movable block 74, so that the second clamping member 722 always remains parallel to the first clamping member 721 during the rotation of the movable block 74.

[0068] Specifically, the movable block 74 can also be in an inverted L shape. The second clamping member 722 is installed on the upper horizontal end 741, and the middle position of the lower vertical end 742 is rotatably connected to the clamping seat 71. The second clamping member 722 on the horizontal end 741 is located above the first clamping member 721 and can perform opening and closing actions relative to the first clamping member 721.

[0069] The structure of the power member 75 is adaptively installed according to the shape of the movable block 74. The output end of the first cylinder 751 in the power member 75 can be telescopically extended horizontally and abuts against the horizontal end 741. The mutually pressing structure can transmit power and can also adapt to the changes after the swinging of the movable block 74, with better adaptability. The first elastic member 752 can still be a tension spring, which acts elastically on the movable block 74 to drive the elastic recovery of the movable block 74. The shape of the movable block 74 can be adaptively bent according to the position of the spring to avoid interference.

[0070] As Figure 6 shown, another rotating structure can also be adopted between the first clamping member 721 and the second clamping member 722 of the clamping assembly 7. In this embodiment, the movable block 74 is rotatably connected to the clamping seat 71, and the axis of the rotating shaft is in a horizontal state and perpendicular to both the first clamping member 721 and the second clamping member 722. During the rotation of the movable block 74, the first clamping member 721 and the second clamping member 722 form an opening and closing state of a scissor mouth, and the formed clamping mouth 73 forms a flared mouth with an enlarged outer end, so that the clamping mouth 73 can more easily align with the socks at the sock feeding path 4.

[0071] Specifically, movable frames 743 are fixedly connected to both sides of the movable block 74. The middle section of the movable frame 743 is rotatably connected to the clamping seat 71 through a rotating shaft. The upper end of the movable frame 743 fixes the movable block 74 and connects the first elastic member 752; the lower end is pressed and driven by the output end of the first cylinder 751 to drive the swinging of the movable block 74 to realize the reciprocating movement of the second clamping member 722.

[0072] Embodiment 3

[0073] This embodiment discloses a reciprocating sock conveyor of a sock knitting machine. On the basis of Embodiment 1 or 2, with reference to Figure 7 、 8 for description; compared with the above, the structure of the driving assembly 8 is redesigned, and the socks can be conveyed in a reciprocating movement manner to replace the rotary conveying manner.

[0074] The clamping assembly 7 is driven by the driving assembly 8 and can reciprocate between a starting position and an ending position, where the starting position is located on the sock feeding path; and the distance between the ending position and the cylinder assembly is greater than the distance between the starting position and the cylinder assembly 101. During operation, the open clamping assembly 7 is first located at the starting position and can clamp the sock at the sock feeding path 4; then it moves towards the ending position. Since the ending position is farther away from the cylinder assembly 101, it can pull the sock outwards from the cylinder assembly 101; then the clamping assembly 7 opens and moves back to the starting position, repeating continuously until the sock is pulled out of the cylinder assembly 101.

[0075] The driving assembly 8 includes a driving base 82, a driving block 85, a guiding member 83, and a driving mechanism 84. Among them, the driving base 82 is installed on the moving assembly 9 to form a basic support. The driving base 82 and the driving block 85 are guided and slid by the guiding member 83, so that the driving block 85 can reciprocate along the direction of the sock feeding path 4 and is driven by the driving mechanism 84 to pull the clamped sock towards the direction of the sock sewing machine 2 for sock conveying. Both the first clamping member 721 and the second clamping member 722 adopt fixed structures and are respectively installed on the clamping base 71 and the movable block 74, making the clamping of the sock more stable.

[0076] As Figure 7 shown, the driving assembly 8 can adopt a reciprocating sliding structure, and the guiding member 83 adopts a slide rail and is arranged along the direction of the sock feeding path 4. When the driving assembly 8 slides along the slide rail to the position at one end close to the cylinder assembly 101, it is at the starting position, as Figure 7 shown; when it slides along the slide rail to the position at one end close to the sewing tooth disc 202, it is at the ending position, as Figure 8 shown;

[0077] Specifically, the slide rail, the driving block 85, and the clamping base 71 are fixed to each other, and the driving base 82 is slidably adapted to the slide rail to form a sliding connection structure. The driving mechanism 84 adopts a telescopic member that can perform reciprocating linear motion, such as a cylinder. The fixed end of the driving mechanism 84 is installed on the driving base 82, and the output end is connected to the driving block 85 to drive the driving block 85 and the clamping assembly 7 to slide.

[0078] As Figure 9 shown, the driving base 82 and the driving block 85 can also adopt a rotational connection method, and the reciprocating movement of the driving block 85 and the clamping assembly 7 is realized through swinging. When the driving assembly 8 swings to the position on the side close to the cylinder assembly 101, it is at the starting position; when it swings to the position on the side close to the sewing tooth disc 202, it is at the ending position;

[0079] The guiding member 83 is a rotating shaft 86, and the driving mechanism 84 is a rotary driver. For example, a driving motor 81 can be adopted. The driving block 85 is rotatably connected to the driving seat 82 through the rotating shaft 86. The driving motor 81 can drive the driving block 85 to swing reciprocally. A clamping assembly 7 is installed at the upper end of the driving block 85. During the swinging process of the driving block 85, the clamping assembly 7 can move reciprocally along the general direction of the sock feeding path 4. When the driving block 85 moves towards the knitting machine 1, the clamping opening 73 of the clamping member 72 opens to allow the sock to enter. When moving towards the sewing machine 2, the clamping member 72 clamps the sock and can pull the sock out of the knitting machine 1.

[0080] Embodiment 4

[0081] This embodiment discloses a reciprocating sock conveyor for a knitting machine. On the basis of Embodiment 1, with reference to Figure 10 for description; compared with the above, the structure of the moving component 9 is redesigned, and the clamping component 7 can be moved by a swinging method to replace the sliding method.

[0082] As Figure 10 shown, the moving component 9 includes a swinging rod 97 and a swinging motor 98. The lower end of the swinging rod 97 is rotatably connected to the bracket 6, and the upper end is fixedly installed with a clamping seat 71 to support the clamping component 7. The swinging motor 98 is a servo motor, and the output end is connected to the swinging rod 97, which can drive the swinging rod 97 to swing reciprocally. During the swinging process, it can drive the clamping component 7 to move relative to the sock feeding path 4 between the knitting machine 1 and the sewing machine 2. When the upper end of the swinging rod 97 swings downward, the clamping component 7 can be moved to a position away from the sock feeding path 4. When the upper part of the swinging rod 97 swings upward to be almost vertical, the clamping component 7 can be moved to a position close to the sock feeding path 4, and the sock in the sock feeding path 4 falls into the clamping opening 73 of the clamping component 7, and the sock can be clamped and conveyed.

[0083] A stop block 99 can be fixedly installed on the bracket 6 corresponding to one side of the swinging rod 97, and an elastic member three 910 is installed between the stop block 99 and the swinging rod 97 to elastically limit the movement of the swinging rod 97 and prevent the swinging rod 97 from swinging and floating too much and causing collision.

[0084] According to the stroke that the clamping component 7 needs to move, multiple groups of moving components 9 can be set to cooperate in transmission, or the sliding method and the swinging method can be combined with each other to adapt to different sock machines.

[0085] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
