Description

Technical Field

[0001] This invention relates to the field of sewing machines, and more particularly to a sewing machine with a sock-feeding and turning-around function. Background Technology

[0002] Toe-sewing machines are one of the main production equipment in hosiery companies. They are used to process hosiery blanks that have open ends and sew the toe closed.

[0003] When the existing machine is sewing the head, the operator lifts the sock blank, pinches the toe end of the sock blank, and inserts it into the gap of the guide rail of the sewing machine. Then the sewing machine moves the sock blank along the guide rail, and the sewing machine head on it sews the head of the sock blank. In this way, the sock blank with the head sewn is formed into a sock prototype. Finally, the sock prototype leaves the sewing machine along the guide rail and falls into the collection box below.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: During the process of feeding the sock blank onto the guide rail of the sewing machine, the part of the sock blank held by the operator cannot be too long, which increases the difficulty of manual operation. At the same time, the sewing efficiency depends entirely on the operator's feeding speed, which reduces the sewing efficiency to some extent. Furthermore, the sock prototype after sewing needs to be transferred to the next process for manual turning, which requires the use of certain equipment, thus greatly increasing the production cost. Summary of the Invention

[0005] To address the issues of low efficiency in sewing toes and the need for turning the socks inside out after sewing, this invention provides a sewing machine with a material feeding and sock-turning function.

[0006] The sewing machine with a sock-feeding and turning function provided by the present invention adopts the following technical solution:

[0007] A sewing machine with a sock-feeding and turning function includes a sewing machine body; the sewing machine body includes a worktable; a sewing machine head is provided on the upper surface of the worktable; a guide rail is provided on the worktable; the guide rail includes a pair of sock toe clips; it includes a sock blank conveying mechanism, a sock toe clamping mechanism, and a sock-turning mechanism; the sock blank conveying mechanism includes a sock blank conveyor belt; the sock blank conveyor belt includes a sock blank transport belt; the sock blank transport belt is located directly below the pair of sock toe clips; the conveying direction of the sock blank transport belt is parallel to the length direction of the pair of sock toe clips and the conveying speed is the same as the sewing speed of the sewing machine body; a plurality of evenly distributed sock blank holders are provided on the outer surface of the sock blank transport belt; the sock blank holder includes a through-through cylindrical sock blank tube and the sock blank tube is used to hold sock blanks with openings at both ends; the sock-turning mechanism includes a sock drive belt and a lifting drive assembly; the sock blank conveying mechanism includes a sock transmission ... The sub-transmission belt includes a sock conveyor belt; the sock conveyor belt is located directly below the sock blank conveyor belt; the sock conveyor belt and the sock blank conveyor belt have opposite conveying directions and the same conveying speed; a plurality of evenly distributed sock-turning seats are provided on the outer surface of the sock conveyor belt; the number of sock-turning seats and sock blank sleeve seats are equal and correspond one-to-one; the sock-turning seat includes a sock-turning sleeve post; the lifting drive assembly is used to drive the sock-turning sleeve post vertically away from or towards the sock conveyor belt; the sock-turning sleeve post is used to insert into the sock blank cylinder on the corresponding side and so that the sock is sleeved on the sock-turning sleeve post; the sock toe clamping mechanism includes a sock toe clamping assembly; the sock toe clamping assembly is located on the feeding side of the sewing machine body and directly above the sock blank conveying mechanism; the sock toe clamping assembly is used to clamp the upper end of the sock blank sleeved on the sock blank cylinder.

[0008] By adopting the above technical solution, the operator places a sock blank onto the sock blank cylinder. Then, as the sock blank is conveyed to the feed side of the sewing machine body, the sock toe clamping mechanism clamps the upper end of the sock blank and moves synchronously with the sock blank conveyor belt. The toe of the sock blank is then inserted between a pair of sock toe clamps. Next, the sock toe clamping assembly releases the sock blank. Then, the sock blank moves towards the discharge side under the combined action of the sewing machine body and the sock blank conveyor belt. During this process, the sewing machine head sews the sock toe into a basic sock shape. Finally, the sock detaches from the pair of sock toe clamps. As the sock blank conveyor belt continues to transport the socks until they are directly aligned with the sock-turning post, the sock blank conveyor belt and the sock blank conveyor belt travel in opposite directions at the same speed. During this process, the sock-turning post, driven by the lifting drive assembly, gradually inserts into the sock blank cylinder and then detaches from it. Simultaneously, the socks are gradually placed on the sock-turning post to complete the turning process and exit the sock blank cylinder. Finally, the socks can be manually pulled out. This eliminates the need for manual feeding and subsequent sock turning, significantly improving sock production efficiency.

[0009] Optionally, the sock toe clamping mechanism further includes a clamping support frame; the sock toe clamping assembly includes a horizontally arranged synchronous linkage electric cylinder fixed on the clamping support frame; the extension and retraction direction of the synchronous linkage electric cylinder is parallel to the conveying direction of the sock blank conveyor belt; a reciprocating moving seat is fixed on the piston rod of the synchronous linkage electric cylinder; a vertically extending and retracting vertical lifting electric cylinder is fixed on the reciprocating moving seat; a claw support plate is fixed at the lower end of the piston rod of the vertical lifting electric cylinder; a claw cylinder is fixed on the lower end surface of the claw support plate.

[0010] By adopting the above technical solution, the synchronous linkage electric cylinder starts and drives the reciprocating moving seat to move together with the sock blank conveyor belt. During this process, the vertical lifting electric cylinder drives the claw support plate to descend, and the claw cylinder starts to clamp the upper end of the sock blank until it enters between a pair of sock toe clamps. Then the claw cylinder releases the upper end of the sock blank, and then the synchronous linkage electric cylinder drives the reciprocating moving seat to return to its original position quickly. During this process, the vertical lifting electric cylinder also returns to its original position.

[0011] Optionally, the clamping support frame includes a vertically arranged vertical support part; a horizontal support part is formed at the upper end of the vertical support part; a synchronous linkage electric cylinder is fixed on the lower end surface of the horizontal support part; and a through-type inlet and outlet is formed on the vertical support part.

[0012] By adopting the above technical solution, the clamping support frame makes the synchronous linkage electric cylinder higher than the sock blank conveyor belt, and the existence of the inlet and outlet does not affect the subsequent sock blank feeding and sock unloading.

[0013] Optionally, the sock-turning seat further includes a sock-turning support plate fixed to the outer surface of the sock conveyor belt and a U-shaped sock-turning lifting frame with an opening away from the sock conveyor belt; the sock-turning sleeve column is vertically formed at the center of the horizontal part of the sock-turning lifting frame away from the sock conveyor belt; a pair of vertical guide columns are formed on the end face of the sock-turning support plate away from the sock conveyor belt; the horizontal part of the sock-turning lifting frame is vertically sleeved on the pair of vertical guide columns; a pair of cylindrical lifting drive guide columns are formed on the mutually distancing end faces of the pair of vertical parts of the sock-turning lifting frame; the lifting drive assembly includes a pair of columns respectively disposed on both sides of the sock conveyor belt. The guide plate is parallel to the conveying direction of the sock conveyor belt. A pair of lifting guide grooves are formed on the end face of the guide plate near the sock conveyor belt for the sliding of the lifting drive guide post. Each lifting guide groove includes a near portion, a far portion, and a pair of inclined connecting portions. The two ends of the far portion are respectively connected to the two ends of the near portion through the inclined connecting portions. The far portion is located on the upper side of the sock conveyor belt. When the lifting drive guide post is located within the near portion, the sock-turning lifting frame abuts against the sock-turning support plate. When the lifting drive guide post is located within the far portion, the sock-turning lifting frame is furthest from the sock-turning support plate.

[0014] By adopting the above technical solution, as the sock conveyor belt conveys the socks, the sock-turning support plate and the sock-turning lifting frame move together. The four lifting drive guide columns move along the lifting guide grooves on their respective sides. When the lifting drive guide column is located in the near part, the sock-turning lifting frame abuts against the sock-turning support plate; when the lifting drive guide column is located in the far part, the sock-turning lifting frame is furthest away from the sock-turning support plate. In this way, the lifting of the sock-turning lifting frame and the sock-turning column is completed without affecting the normal operation of the sock conveyor belt.

[0015] Optionally, the sock blank conveyor belt further includes four rectangularly distributed sock blank conveyor support feet; a sock blank conveyor roller is pivotally connected between the upper ends of a pair of sock blank conveyor support feet on the same side; the sock blank conveyor roller is perpendicular to the conveying direction of the sock blank conveyor belt; the sock blank conveyor belt is disposed between a pair of sock blank conveyor rollers; a sock blank conveyor motor is fixed on one of the sock blank conveyor support feet located on the discharge side of the sewing machine body; the output shaft of the sock blank conveyor motor is fixedly connected to the rotation center shaft of the sock blank conveyor roller on the corresponding side.

[0016] By adopting the above technical solution, the sock blank conveyor motor drives the sock blank conveyor roller on the corresponding side to rotate, and under the guidance of the other sock blank conveyor roller, the sock blank conveyor belt completes the conveying.

[0017] Optionally, the sock conveyor belt further includes four rectangularly distributed sock conveying support feet; a sock conveying roller is pivotally connected between the upper ends of a pair of sock conveying support feet on the same side; the sock conveying roller is perpendicular to the conveying direction of the sock conveyor belt; the sock conveyor belt is positioned between a pair of sock conveying rollers; a sock conveying motor is fixed on one of the sock conveying support feet on the feeding side of the sewing machine body; the output shaft of the sock conveying motor is fixedly connected to the rotation center shaft of the sock conveying roller on the corresponding side.

[0018] By adopting the above technical solution, the sock conveyor motor drives the sock conveyor roller on the corresponding side to rotate, and under the guidance of the other sock conveyor roller, the sock conveyor belt completes the conveying.

[0019] Optionally, the sock blank holder further includes a sock blank support fixed to the outer surface of the sock blank conveyor belt; the sock blank cylinder is vertically formed on the end face of the sock blank support away from the sock blank conveyor belt; an air inlet groove is formed on one end face of the sock blank support perpendicular to the outer surface of the sock blank conveyor belt and parallel to the conveying direction of the sock blank conveyor belt; an air outlet is formed on the end face of the sock blank support away from the sock blank conveyor belt; one end of the air outlet communicates with the air inlet groove, and the other end opens directly opposite the opening of the sock blank cylinder; a blowing mechanism is also provided on the feeding side of the sewing machine body; the blowing mechanism includes a blowing support, a following moving seat, and an air supply nozzle; a following drive assembly is provided on the blowing support; the following drive assembly is used to drive the following moving seat to reciprocate along the conveying direction of the sock blank conveyor belt; a connecting drive assembly is provided on the following moving seat; the connecting drive assembly is used to drive the air supply nozzle to insert into or disengage from the air inlet groove; the air supply nozzle is connected to an external air supply device.

[0020] By adopting the above technical solution, the following drive component drives the following moving seat to move synchronously with the sock blank conveyor belt. During this process, the connecting drive component drives the air supply nozzle to be inserted into the air inlet groove. The air supply device supplies air so that the airflow enters the sock blank cylinder through the air supply nozzle, air inlet groove and air outlet and is ejected from the opening of the sock blank cylinder away from the sock blank conveyor belt. This ejected gas ensures that the upper end of the sock blank sleeved on the sock blank cylinder is in a vertical state, which makes it convenient for the subsequent sock toe clamping component to clamp the upper end of the sock blank sleeved on the sock blank cylinder.

[0021] Optionally, a pair of reciprocating support plates are formed on the air-blowing support base; a pair of reciprocating guide posts are formed between the pair of reciprocating support plates and a reciprocating drive screw is pivotally connected thereto; the axial directions of the reciprocating drive screw and the reciprocating guide posts are parallel to the conveying direction of the sock blank conveyor belt; a reciprocating drive motor is fixed on the reciprocating support plate; the output shaft of the reciprocating drive motor is fixedly connected to the reciprocating drive screw; the lower end of the following moving seat is sleeved on the pair of reciprocating guide posts and screwed onto the reciprocating drive screw.

[0022] By adopting the above technical solution, the reciprocating drive motor drives the reciprocating drive screw to rotate, so that the follower moving seat, which is screwed to the reciprocating drive screw, moves along a pair of reciprocating guide posts. The forward or reverse rotation of the reciprocating drive motor can drive the follower moving seat to move back and forth.

[0023] Optionally, the connecting drive assembly includes a connecting drive electric cylinder fixed on the accompanying moving seat; the extension and retraction direction of the connecting drive electric cylinder is perpendicular to the conveying direction of the sock blank conveyor belt; an air nozzle support plate is fixed on the piston rod of the connecting drive electric cylinder; and the air supply nozzle is fixed on the end face of the air nozzle support plate away from the connecting drive electric cylinder.

[0024] By adopting the above technical solution, the connecting electric cylinder drives the air nozzle support plate to move closer to or away from the sock blank support seat, so that the air supply nozzle on the air nozzle support plate can be inserted into or removed from the air inlet groove.

[0025] Optionally, the sock blank cylinder is a rectangular shell with openings at the top and bottom; the sock-turning column is a rectangular prism; the length direction of the horizontal cross-section of the sock blank cylinder and the sock-turning column is parallel to the conveying direction of the sock blank conveyor belt.

[0026] By adopting the above technical solution, the upper end of the sock blank, which is fitted onto the sock blank cylinder, is easily aligned with the same straight line when clamped by the sock toe clamping component, which facilitates subsequent entry into the gap between a pair of sock toe clamps and the seam.

[0027] In summary, the beneficial effects of the present invention are as follows:

[0028] 1. No manual feeding or subsequent sock turning is required, greatly improving sock production efficiency.

[0029] 2. Facilitates the subsequent clamping of the sock toe clamping assembly onto the upper end of the sock blank, which is fitted onto the sock blank cylinder. Attached Figure Description

[0056] During operation, the air blowing mechanism 40 uses a reciprocating drive motor to drive the reciprocating drive screw 42 to rotate forward or reverse, thereby causing the accompanying moving seat 43 to move back and forth along a pair of reciprocating guide posts 412. Initially, the accompanying moving seat 43 is at the leftmost position. When the sock blank holder 24 reaches the position of the accompanying moving seat 43 from left to right along with the sock blank conveyor belt 23, the accompanying moving seat 43 begins to move synchronously with the sock blank conveyor belt 23. During this process, the connected drive cylinder 45 drives the air nozzle support plate 451 to move forward, supplying air. The nozzle 46 is inserted into the air inlet groove 2410, and the external air supply device supplies air. The air supply nozzle 46 sprays out airflow, which travels along the air inlet groove 2410 and the air outlet 2411, and finally sprays out along the sock blank cylinder 242. In this way, the upper end of the sock blank sleeved on the sock blank cylinder 242 is in a vertical state under the action of airflow, which makes it convenient for the subsequent clamping cylinder 36 to clamp the upper end of the sock blank. Then the nozzle support plate 451 moves back to its original position, and finally the accompanying moving seat 43 moves to the left to its original position, waiting for the next sock blank sleeve 24 to enter.

[0057] The working principle of the sewing machine with a sock-feeding and turning function described in this application is as follows:

[0058] The operator places a sock blank onto the leftmost sock blank cylinder 242 at the inlet / outlet 310. As the sock blank is conveyed by the sock blank conveyor belt 23 to the left side of the sewing machine body 10, the synchronous linkage electric cylinder 32 drives the reciprocating moving seat 33 to move synchronously with the sock blank conveyor belt 23. During this process, the vertical lifting electric cylinder 34 lowers the claw support plate 35, and then the claw cylinder 36 clamps the upper end of the sock blank. The toe of the sock blank is then inserted between the gaps of a pair of sock toe clips 14. Next, the claw cylinder 36 releases the sock blank, and the synchronous linkage electric cylinder 32 drives the reciprocating moving seat 33 back to its original position. During this process, the vertical lifting electric cylinder 34 raises the claw support plate 35 back to its original position to await the entry of the next sock blank. Then, the sock blank moves to the right under the combined action of the sewing machine body 10 and the sock blank conveyor belt 23. During this process, the sewing machine head 13 sews the toe of the sock blank into a basic sock shape, and then the sock is removed. A pair of sock toe clips 14 continue to be conveyed along the sock blank conveyor belt 23 until the sock is located under the sock blank conveyor belt 23. At this time, the sock-turning column 543 of the sock conveyor belt 53 is facing the sock. Since the sock conveyor belt 53 and the sock blank conveyor belt 23 have opposite conveying directions and the same conveying speed, during the conveying process, the sock-turning lifting frame 542 will move away from or closer to the sock blank cylinder 242 under the cooperation of the four lifting drive guide columns 5421 and the two pairs of lifting guide grooves 550 of the pair of guide plates 55. The sock-turning column 543 on the sock-turning lifting frame 542 will gradually insert into the sock blank cylinder 242 and then gradually detach from the sock blank cylinder 242. During this process, the sock is gradually put on the sock-turning column 543 to complete the sock-turning and leave the sock blank cylinder 242. Finally, the operator can pull out the sock at the inlet / outlet 310. This eliminates the need for manual feeding and subsequent sock-turning, greatly improving the sock production efficiency.

[0059] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
