Description

TECHNICAL FIELD

[0001] The application belongs to the technical field, and particularly relates to a knitting needle automatic arrangement and detection integrated device. BACKGROUND

[0002] The quality of knitting needles directly determines the grade of fabrics. However, in the production process, the knitting needles are easily damaged due to their high-frequency motion characteristics, and if they are not replaced in time, a large number of fabric defects will be caused, so the detection of the knitting needles is very important. However, in the actual production process of the knitting needles, a large amount of manual labor is still used for the detection of the knitting needles, and the workers have to work for a long time, with high intensity and low arrangement efficiency.

[0003] Specifically, since the knitting needles are small in size and light in texture, it is difficult to sort out the deformed and defective knitting needles from a large number of knitting needles in the manual sorting process. At the same time, for some knitting needles, the defects are not obvious, so the error rate is relatively high in the manual sorting process, that is, it is easy to regard the knitting needles with defects such as insufficient deformation as qualified knitting needles, and then install them in the equipment to cause a large number of defective knitted fabric products in the knitting process.

[0004] In order to more efficiently detect and sort the knitting needles, a kind of knitting needle defective product detection and sorting device is disclosed in Chinese patent No. CN217528310U. Specifically, a plurality of knitting needle limiting grooves are arranged on the surface of the conveying belt, and the conveying belt is connected with the output shaft of the stepping motor at one end. The conveying belt is fixed on the support frame, the infrared detector is fixed on the upper end of the support frame, the sorting bin is fixed on the bottom of the conveying belt, the needle leakage device is fixed on the bottom of the limiting groove, and the needle leakage device is fixedly connected with the control device on one side of the conveying belt through the connecting rod. The limiting grooves are arranged in the transverse direction of the conveying belt, the width and length of each limiting groove are the same as the size of the knitting needle to be detected, the driving rack is arranged on the side of the conveying belt away from the limiting groove, the driving rack is in a long strip shape, and the conveying belt is fixed outside the rack. The above structure realizes the sorting according to the size of the knitting needle.

[0005] However, the above-mentioned patent and the prior art cannot realize the accurate sorting of a large number of mixed knitting needles including defective knitting needles, qualified knitting needles, and different types and different models of knitting needles. SUMMARY

[0049] Preferably, a plurality of accommodation grooves are arranged on the needle collecting box.

[0050] The present application has the following advantages:

[0051] 1. During the working process, a large number of knitting needles are sorted and inspected and then fed into the needle sorting module. The needle sorting module then feeds the knitting needles into the needle feeding module according to the correct posture. The needle feeding module then passes through the needle detection module for inspection. The needle detection module, together with the needle collection module, classifies and collects the knitting needles according to their condition, such as defective and non-defective needles. This method solves the technical problem of accurately sorting out defective knitting needles when there are a large number of knitting needles mixed together.

[0052] 2. During the operation, when the knitting needle enters the dividing section, the rack moves under the push of the dual-axis cylinder, driving the gear to rotate. Because the dividing section is fixedly connected to the gear, the rotation of the dividing section will cause the knitting needle placed on the dividing section to fall down and onto the transmission screw below.

[0053] The advantage of this method is that it cleverly utilizes gears, racks, and dual-axis cylinders to flip the knitting needles during feeding, ensuring that the needles remain in a vertical position after feeding.

[0054] 3. During operation, driven by the geared motor, the two transmission screws rotate synchronously. The knitting needles, fed onto the screws, are propelled by the threaded grooves on the transmission screws. In this process, the cleverly designed threaded grooves on the transmission screws serve two purposes: firstly, to support and push the knitting needles, and secondly, to utilize the threaded structure of the grooves to propel and transport them. This transport method also has the advantage of maintaining the knitting needles' posture vertically during transport, facilitating accurate detection by subsequent inspection modules.

[0055] 4. The working process begins with the rotary table rotating until the feeding structure on the needle feeder faces the transmission screws (the knitting needles are mounted on the threaded grooves of a pair of transmission screws and transmitted to the feeding structure near the needle feeder). Then, the lifting screw structure drives the rotary table to rise until the height of the limiting slot structure corresponds to the height of the feeding needles, and the needles are fed. After feeding, the feeding structure is rotated to the other side to prepare for needle detection by the needle detection module. After detection, feeding can continue. This process cleverly improves the feeding structure on the needle feeder, ensuring that the feeding needles maintain a vertical limiting posture during feeding and unloading. Simultaneously, after feeding is completed, the idle feeding structure can be rotated to continue feeding, increasing feeding efficiency.

[0056] 5. The needle sorting device disclosed in this invention achieves automated sorting and classification of disordered needles, effectively solving the technical defect of being unable to remove defective needles from a large number of disordered needles. This automated sorting method greatly improves sorting efficiency while reducing the labor intensity of manual sorting. Attached Figure Description

[0071] Example 1

[0072] like Figures 1-9 As shown, an integrated device for automatic knitting needle sorting and inspection includes a needle sorting module 1, a needle feeding module 2 at the outlet end of the needle sorting module 1, and a needle detection module 3 at the outlet end of the needle feeding module 2. The device also includes a needle collection module 4. After inspection by the needle detection module 3, the needles are sorted and collected by the needle collection module 4. During operation, a large number of knitting needles 1-15 are fed into the needle sorting module 1, which then feeds them into the needle feeding module 2 according to their correct posture. The needles are then inspected by the needle detection module 3. The needle detection module 3, in conjunction with the needle collection module 4, sorts and collects the knitting needles 1-15 according to their condition, i.e., defective and undefective. This method solves the technical problem of accurately sorting out defective knitting needles from a large number of mixed knitting needles.

[0073] Example 2

[0074] like Figures 1-9 As shown, this embodiment discloses the specific structure of the needle-fixing module 1 based on the structure of embodiment 1.

[0075] The needle-arranging module 1 includes a needle-arranging device frame 1-1 (with feet 1-19 mounted on the bottom), and a needle-arranging vibration feeding mechanism is mounted on the top of the needle-arranging device frame 1-1. Specifically, the needle-arranging vibration feeding mechanism includes a curved vibratory plate 1-14 mounted on the top of the needle-arranging device frame 1-1; a vibration motor 1-16 is mounted on the bottom of the curved vibratory plate 1-14; a vibratory plate base is fixedly mounted on the top of the needle-arranging device frame 1-1; and the vibration motor 1-16 is mounted on the top of the vibratory plate base.

[0076] Meanwhile, a straight vibrating plate 1-17 is fixedly installed at the discharge end of the curved vibrating plate 1-14; a vibrating tray 1-18 is fixedly connected to the bottom of the straight vibrating plate 1-17, and the vibrating tray 1-18 is fixedly connected to the top of the knitting needle finishing device frame 1-1; a number of guide grooves for guiding knitting needles 1-15 are opened on the straight vibrating plate 1-17.

[0077] During the operation, a large number of knitting needles 1-15 are placed into the curved vibrating plate 1-14. Under the vibration of the curved vibrating plate 1-14, the knitting needles gradually move to the vibrating plate 1-17 and, with the assistance of vibration, the knitting needles correct their posture and move along the guide groove of the straight vibrating plate 1-17 to feed the material. During this process, the knitting needles are limited by the guide groove, so the knitting needles maintain a precise posture for feeding the material.

[0078] Example 3

[0079] like Figures 1-9 As shown, in this embodiment, based on the structure of embodiment 2, a needle guiding mechanism is provided at the discharge end of the needle vibrating feeding mechanism to feed the knitting needles from the guide groove on the straight vibrating plate 1-17. Specifically, the needle guiding mechanism includes a faceted groove 1-20, which includes several faceted sections that cooperate with the guide groove, that is, the knitting needles from the guide groove enter each faceted section.

[0080] The specific shape of the dividing section is as follows: the dividing section includes a cylindrical part 1-201 fixedly connected to the connecting shaft, and the cylindrical part 1-201 is integrally formed with an L-shaped part 1-202. After the knitting material is fed from the guide groove, it falls into the groove formed by the L-shaped part and the cylindrical part.

[0081] Meanwhile, the needle guiding mechanism also includes a dual-axis cylinder 1-101, on which a dual-axis precision slide cylinder platform 1-10 is fixedly installed;

[0082] The top of the dual-axis precision spool stage 1-10 is fixedly connected to a rack 1-11; specifically, the top of the dual-axis precision spool stage 1-10 is fixedly connected to a rack seat 1-9, and the top of the rack seat 1-9 is fixedly connected to the rack 1-11.

[0083] Correspondingly, the needle guide mechanism also includes a gear seat 1-13, on which a plurality of gears 1-12 meshing with a rack 1-11 are rotatably connected. A connecting shaft is fixedly connected to the gears 1-12, and the connecting shaft is fixedly connected to the dividing section (specifically on the cylindrical part 1-201).

[0084] In the working process, when the knitting needles 1-15 enter into the split part, at this time, under the pushing of the double-shaft type cylinder 1-101, the rack 1-11 moves to drive the gear 1-12 to rotate, and since the gear 1-12 is fixedly connected to the split part, the rotation of the split part causes the split part to rotate, so that the split part rotates to flip down the knitting needles 1-15 placed on the split part to fall onto the transmission screw 1-8 described below.

[0085] The advantage of this mode is that the gear 1-12, the rack 1-11 and the double-shaft type cylinder 1-101 structure are ingeniously utilized to realize the flipping of the discharged knitting needles and the maintaining of the vertical posture of the knitting needles after the discharge.

[0086] Specifically, the needle straightening module 1 further comprises a screw feeding mechanism cooperating with the knitting needle guiding mechanism; the knitting needles are corrected in posture by the needle straightening and vibrating discharge mechanism and then enter into the knitting needle guiding mechanism, and the knitting needles are discharged to the screw feeding mechanism after being flipped by the knitting needle guiding mechanism; the screw feeding mechanism comprises a pair of transmission screws 1-8 arranged side by side, the discharged knitting needles 1-15 are supported between the thread grooves of the transmission screws 1-8, and the knitting needles are pushed to the needle feeding module 2 by the transmission screws 1-8.

[0087] Specifically, the screw feeding mechanism further comprises a transmission screw rack, and a screw bearing seat 1-7 for rotatingly connecting the transmission screw 1-8 is fixedly installed on the transmission screw rack. Meanwhile, the end of the transmission screw 1-8 is fixedly connected with a belt wheel 1-6 for driving the transmission screw 1-8 to rotate.

[0088] The screw feeding mechanism further comprises a speed reducer motor 1-3 (the speed reducer motor 1-3 is installed on a speed reducer motor fixing plate 1-2), a large belt wheel 1-4 is installed on the output shaft of the speed reducer motor 1-3, and the large belt wheel 1-4 and the belt wheel 1-6 are driven by a V-shaped belt 1-5 arranged in a V shape.

[0089] In the working process, under the driving of the speed reducer motor 1-3, the two transmission screws 1-8 rotate synchronously, and the knitting needles discharged on the pair of transmission screws 1-8 are pushed by the thread grooves of the transmission screws 1-8.

[0090] In this process, the thread grooves on the transmission screws 1-8 are ingeniously utilized to support and push the knitting needles, and the thread structure of the thread grooves is utilized to push and transport the knitting needles. The advantage of this transportation mode is that the posture of the knitting needles can be maintained unchanged during the transportation, that is, the knitting needles are in the vertical posture, which facilitates the accurate detection of the subsequent detection module.

[0091] Embodiment 4

[0092] As Figures 1-9As shown, the embodiment is based on the structure of embodiment 1, and the needle feeding module 2 comprises a needle feeding frame 2-1. The needle feeding frame 2-1 (the needle feeding frame 2-1 comprises a rectangular frame plate body 2-101 and four convexly arranged convex parts) is provided with four feeding structures arranged in a rectangle and matched with the lead screw feeding mechanism (one feeding structure is arranged on each convex part).

[0093] Specifically, the feeding structure comprises a needle limiting plate 2-102, and a limiting slot 2-1021 for limiting the needle is formed between the bottom of the needle limiting plate 2-102 and the top of the needle feeding frame 2-1.

[0094] Specifically, the needle limiting plate 2-102 is integrally formed with an arc-shaped convex part matched with the shape of the needle, and the bottom forms an arc-shaped groove structure. Correspondingly, a pad matched with the shape of the arc-shaped groove is fixedly connected to the top of the needle feeding frame 2-1, so that the space structure between the pad and the arc-shaped groove structure is matched with the shape of the needle, that is, the limiting slot 2-1021 structure is formed, which facilitates the limiting of the needle by the limiting slot 2-1021 while keeping the needle in a vertical state after feeding.

[0095] Meanwhile, a rotating structure is installed at the bottom of the needle feeding frame 2-1, and the needle feeding module 2 further comprises a lifting lead screw structure for lifting the needle feeding frame 2-1.

[0096] Specifically, the rotating structure comprises a rotating table 2-2 (the rotating table 2-2 is a freely rotatable rotating table, and the structure principle is that the rotating table part on the rotating table 2-2 is driven to rotate by a motor). That is, the needle feeding frame 2-1 is fixedly installed on the rotating table part of the rotating table 2-2, so as to realize the rotation switching of the orientation of the feeding structure by the rotating table 2-2.

Specifically, under the driving of the two-phase hybrid stepping motor 2-6, the lifting of the rotating table 2-2 is realized.

[0098] The working process is as follows: first, the rotating table 2-2 is rotated to the feeding structure on the needle feeding frame 2-1 facing the transmission lead screw 1-8 (the needle is driven on the thread groove of a pair of transmission lead screws 1-8 to the feeding structure close to the needle feeding frame 2-1), then the lifting lead screw structure drives the rotating table 2-2 to rise to the height corresponding to the limiting slot 2-1021 structure and the fed needle, and then the needle is fed. In the working process, in order to increase the transmission stability of the transmission lead screw 1-8, a lead screw bearing frame 2-7 is installed near the position of the transmission lead screw 1-8 close to the needle feeding frame 2-1.

[0099] After the feeding is completed, the feeding structure is selected to rotate to the other side to prepare for detection by the needle detection module 3, and after detection, the feeding can continue to be transmitted.

[0100] In this process, the feeding structure on the needle feeding rack 2-1 is ingeniously improved, and the feeding needles can be fed vertically and positioned in a vertical position, and at the same time, after the feeding is completed, the idle feeding structure can be continuously rotated for feeding to increase the feeding efficiency.

[0101] Subsequently, the feeding needles that have completed feeding are fed to the needle feeding rack 2-1 for rapid detection, and after detection, the feeding is completed, and the feeding structure that has been fed is continuously rotated to the position for detection, so that the feeding efficiency of the needles is greatly improved.
