Description

Technical Field

[0001] The invention belongs to the technical field, and in particular relates to an integrated device for automatic arrangement and detection of knitting needles. Background Art

[0002] The quality of knitting needles directly determines the grade of fabrics. However, during the production process, knitting needles are easily damaged due to their high-frequency movement characteristics. If they are not replaced in time, a large number of fabric defects will be generated. Therefore, knitting needle detection is very important. However, in the actual knitting needle production process, knitting needle detection still uses a lot of manual labor, workers have long working hours, high intensity, and low finishing efficiency.

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

[0004] Based on this, in order to more efficiently detect and sort knitting needles, the Chinese patent publication number is: CN217528310U, which discloses a defective knitting needle detection and sorting device. Specifically, a plurality of knitting needle limit grooves are arranged on the surface of the conveyor belt, and one end of the conveyor belt is connected to the output shaft of the stepper motor; the conveyor belt is fixed on the support frame, and an infrared detector is fixed on the upper end of the support frame. A sorting bin is fixed at the bottom of the conveyor belt, and a missing needle device is fixed at the bottom of the limit groove. The missing needle device is fixedly connected to the control device on one side of the conveyor belt through a connecting rod. There are multiple limit grooves along the transverse direction of the conveyor belt, and the width and length of each limit groove are the same as the size of the knitting needle to be detected. A drive rack is arranged on the side of the conveyor belt away from the limit groove. The drive rack is a long strip type, and the conveyor belt is fixed outside the rack. The above structure realizes sorting according to the size of the knitting needles.

[0005] However, the technical solutions disclosed in the above patents and the prior art are unable to accurately sort a large number of mixed knitting needles including defective knitting needles, qualified knitting needles and knitting needles of different types and models.

[0050] The present invention has the following beneficial effects:

[0051] 1. During the working process, a large number of knitting needles that have been sorted and tested are loaded into the needle sorting module, and the needle sorting module unloads the knitting needles in the correct posture into the needle feeding module and sends them to the needle detection module for detection. The needle detection module cooperates with the needle collection module to realize classification and collection according to the conditions of the knitting needles, such as defective and non-defective knitting needles. In this way, the technical defect that it is difficult to accurately sort out defective knitting needles from a large number of mixed knitting needles is solved.

[0052] 2. During the working process, when the knitting needle enters the dividing surface, the rack moves under the push of the double-axis cylinder, driving the gear to rotate. Because the dividing surface fixedly connected by the gear rotates, the knitting needle placed on the dividing surface rotates and falls onto the transmission screw below.

[0053] The advantages of this method are: the gear, rack and double-axis cylinder structure are cleverly used to flip the knitting needles for unloading, so that the vertical posture of the needles remains unchanged after unloading.

[0054] 3. During the working process, driven by the reduction motor, the transmission screws on both sides rotate synchronously, and the knitting needles on a pair of screws are pushed by the thread grooves of the transmission screws. In this process, the thread grooves are cleverly opened on the transmission screws to support and push the knitting needles, and the thread structure of the thread grooves is used to push and transport the knitting needles. The advantage of this transportation method is that the posture of the knitting needles can be kept unchanged during transportation, in a vertical posture, which is convenient for the subsequent detection module to accurately detect.

[0055] 4. To realize the working process, first the rotating table rotates until the feeding structure on the needle feeding frame faces the transmission screw (the knitting needles are mounted on the screw thread grooves of a pair of transmission screws and are transmitted to the feeding structure close to the needle feeding frame), and then the lifting screw structure drives the rotating table to rise until the limit slot structure corresponds to the height of the knitting needles to be fed, and then the knitting needles are fed. After the feeding is completed, the feeding structure is rotated to the other side to prepare for the needle detection module to detect, and the material can be continued to be unloaded and transmitted after the detection. In this process, the feeding structure on the needle feeding frame is cleverly improved, so that the knitting needles for feeding can maintain a vertical limit posture for feeding and unloading. At the same time, after the feeding process is completed, the idle feeding structure can continue to rotate to feed, so as to increase the feeding efficiency.

[0056] 5. The knitting needle sorting device disclosed in the present invention realizes the classification of disordered knitting needles with an automatic degree, and effectively solves the technical defect that defective knitting needles cannot be removed and sorted from a large number of disordered knitting needles. The above-mentioned method automates the sorting operation, greatly improving the sorting efficiency and reducing the labor intensity of manual sorting. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] Example 1

[0072] like Figure 1-9 As shown, an integrated device for automatic sorting and detection of knitting needles includes a needle sorting module 1, a needle feeding module 2 is provided at the discharge end of the needle sorting module 1, and a needle detection module 3 is provided at the discharge end of the needle feeding module 2. At the same time, the integrated device for automatic sorting and detection of knitting needles also includes a needle collection module 4, and after detection by the needle detection module 3, the knitting needles are classified and collected by the needle collection module 4. During the working process, a large number of knitting needles 1-15 that have been sorted and detected are loaded into the needle sorting module 1, and the knitting needles are unloaded into the needle feeding module 2 in the correct posture through the needle sorting module 1 and fed to the needle detection module 3 for detection. The needle detection module 3 cooperates with the needle collection module 4 to realize the classification and collection of knitting needles 1-15 according to their conditions, such as defective and non-defective knitting needles. In this way, the technical defect that it is difficult to accurately sort out defective knitting needles from a large number of mixed knitting needles is solved.

[0073] Example 2

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

[0075] The needle arrangement module 1 includes a needle arrangement device frame 1-1 (with a foot 1-19 installed at the bottom), and a needle arrangement vibration unloading mechanism is installed on the top of the needle arrangement device frame 1-1. Specifically, the needle arrangement vibration unloading mechanism includes a curved vibration disk 1-14 installed at the top of the needle arrangement device frame 1-1; a vibration motor 1-16 is installed at the bottom of the curved vibration disk 1-14, and a vibration disk base is fixedly installed on the top of the needle arrangement device frame 1-1, and the vibration motor 1-16 is installed at the top of the vibration disk base.

[0076] At the same time, a straight vibration plate 1-17 is fixedly installed at the discharge end of the curved vibration disk 1-14; a vibration tray 1-18 is fixedly connected to the bottom of the straight vibration plate 1-17, and the vibration tray 1-18 is fixedly connected to the top position of the knitting needle sorting device frame 1-1; a plurality of guide grooves for guiding knitting needles 1-15 are opened on the straight vibration plate 1-17.

[0077] During the working process, a large number of knitting needles 1-15 are placed in the curved vibration disk 1-14. Under the vibration of the curved vibration disk 1-14, the knitting needles gradually move to the vicinity of the material guide groove of the straight vibration plate 1-17, and with the assistance of vibration, the knitting needles correct their posture and move along the material guide groove of the straight vibration plate 1-17 to feed the material. In this process, because the knitting needles are limited by the material guide groove, the knitting needles maintain a precise posture to feed the material.

[0078] Example 3

[0079] like Figure 1-9 As shown, based on the structure of Example 2, in order to discharge the knitting needles discharged from the guide slot on the straight vibration plate 1-17, a knitting needle guide mechanism is provided at the discharge end of the above-mentioned needle arrangement vibration discharge mechanism. Specifically, the knitting needle guide mechanism includes a facet groove 1-20, and the facet groove 1-20 includes a plurality of facet sections that cooperate with the guide slot, that is, the knitting needles discharged from the guide slot enter each facet section.

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

[0081] At the same time, the knitting needle guide mechanism also includes a double-axis cylinder 1-101, and a double-axis precision sliding cylinder table 1-10 is fixedly installed on the piston rod of the double-axis cylinder 1-101;

[0082] The top of the dual-axis precision sliding cylinder platform 1-10 is fixedly connected to a rack 1-11; specifically, the top of the dual-axis precision sliding cylinder platform 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 knitting needle guide mechanism also includes a gear seat 1-13, on which are rotatably connected a plurality of gears 1-12 meshing on the rack 1-11, and on which are fixedly connected a connecting shaft, which is fixedly connected to the dividing surface portion (specifically on the cylindrical portion 1-201).

[0084] During the working process, when the knitting needle 1-15 enters the dividing surface, at this time, under the push of the double-axis cylinder 1-101, the rack 1-11 moves, driving the gear 1-12 to rotate. Since the gear 1-12 is fixedly connected to the dividing surface, the dividing surface rotates. Therefore, the rotation of the dividing surface will turn the knitting needle 1-15 placed on the dividing surface down and fall onto the transmission screw 1-8 described below.

[0085] The advantages of this method are: the gear 1-12, the rack 1-11, and the double-axis cylinder 1-101 structure are cleverly used to turn over the knitting needles for unloading, so that the vertical posture of the needles remains unchanged after unloading.

[0086] Specifically, the needle arrangement module 1 also includes a screw feeding mechanism that cooperates with the needle guide mechanism; the needle arrangement vibration feeding mechanism corrects the posture of the needle and then enters the needle guide mechanism, and the needle guide mechanism flips over and feeds the needle to the screw feeding mechanism; the screw feeding mechanism includes a pair of transmission screws 1-8 arranged side by side, and the knitting needles 1-15 for feeding are supported between the threaded grooves on the transmission screw 1-8, and the knitting needles are pushed to the needle feeding module 2 through the transmission screw 1-8.

[0087] Specifically, the screw feeding mechanism also includes a transmission screw rack, on which a screw bearing seat 1-7 rotatably connected to the transmission screw 1-8 is fixedly mounted. At the same time, the end of the transmission screw 1-8 is fixedly connected to a pulley 1-6 that drives the transmission screw 1-8 to rotate.

[0088] The screw feeding mechanism also includes a reduction motor 1-3 (the reduction motor 1-3 is installed on the reduction motor fixing plate 1-2), and a large pulley 1-4 is installed on the output shaft of the reduction motor 1-3. The large pulley 1-4 and the pulley 1-6 are driven by a V-belt 1-5 arranged in a V shape.

[0089] During the working process, under the drive of the reduction motor 1-3, the transmission screws 1-8 on both sides rotate synchronously, and the knitting needles on a pair of transmission screws 1-8 are pushed by the thread grooves of the transmission screws 1-8 to push the knitting needles.

[0090] In this process, the thread groove on the transmission screw 1-8 is cleverly used to support and push the knitting needles, and the thread structure of the thread groove is used to push and transport the knitting needles. The advantage of this transportation method is that the posture of the knitting needles can be kept unchanged during transportation, in a vertical posture, which is convenient for the subsequent detection module to accurately detect.

[0091] Example 4

[0092] like Figure 1-9As shown, based on the structure of Example 1, the needle feeding module 2 of this embodiment includes a needle feeding frame 2-1, and the needle feeding frame 2-1 (the needle feeding frame 2-1 includes a rectangular frame plate main body 2-101 and four protruding protrusions) is provided with four feeding structures (one feeding structure is provided on each protrusion) distributed in a rectangular shape and cooperating with the screw feeding mechanism.

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

[0094] Specifically, an arc-shaped protrusion that matches the shape of the knitting needle is integrally formed on the knitting needle limiting plate 2-102, and an arc-shaped groove structure is formed at the bottom. Correspondingly, a pad that matches the shape of the arc-shaped groove is fixedly connected to the top of the needle feeding frame 2-1, so that the spatial structure shape between the pad and the arc-shaped groove structure matches the shape of the knitting needle, that is, a limiting slot 2-1021 structure is formed, which is convenient for limiting the knitting needle by using the limiting slot 2-1021 after loading while keeping the knitting needle in a vertical state.

[0095] At the same time, a rotating structure is installed at the bottom of the needle feeding frame 2-1, and the needle feeding module 2 also includes a lifting screw structure that pushes the needle feeding frame 2-1 to rise and fall.

[0096] Specifically, the rotating structure includes a rotating table 2-2 (the rotating table 2-2 is a freely rotatable turntable, and its structural principle is to drive the turntable part of the rotating table 2-2 to rotate by a motor). That is, the needle feeding frame 2-1 is fixedly installed on the turntable part of the rotating table 2-2, so that the orientation of the feeding structure can be switched by rotating the rotating table 2-2.

[0097] At the same time, a lifting screw structure is installed at the bottom of the rotating platform 2-2; the lifting screw structure includes a two-phase hybrid stepper motor 2-6, and a ball screw 2-3 for driving the rotating platform 2-2 to move up and down is installed on the output shaft of the two-phase hybrid stepper motor 2-6 (the motor output shaft is installed on the ball screw 2-3 through a coupling 2-4); the two-phase hybrid stepper motor 2-6 is installed with a motor seat 2-5. Specifically, under the drive of the two-phase hybrid stepper motor 2-6, the lifting and lowering of the rotating platform 2-2 is realized.

[0098] During the working process, the rotating table 2-2 first rotates until the feeding structure on the needle feeding frame 2-1 faces the transmission screw 1-8 (the knitting needles are carried on the screw thread grooves of a pair of transmission screws 1-8 and are transmitted to the feeding structure near the needle feeding frame 2-1), and then the lifting screw structure drives the rotating table 2-2 to rise to the limit notch 2-1021 structure corresponding to the height of the knitting needles to be fed, and then the knitting needles are fed. During the working process, in order to increase the transmission stability of the transmission screw 1-8, a screw bearing frame 2-7 is installed near the position of the transmission screw 1-8 near the needle feeding frame 2-1.

[0099] After the loading is completed, the loading structure is rotated to the other side to prepare for detection by the needle detection module 3, and the unloading and transmission can continue after the detection.

[0100] In this process, the feeding structure on the needle feeding frame 2-1 is cleverly improved so that the knitting needles can maintain a vertical limited position for loading and unloading. At the same time, after the loading is completed, the idle feeding structure can continue to rotate to increase the feeding efficiency.

[0101] Subsequently, the loaded knitting needles are loaded onto the needle feeding rack 2-1 and quickly inspected. After the inspection is completed, the knitting needles are unloaded and the loaded loading structure is rotated to this position for further inspection. This method greatly improves the knitting needle loading efficiency.

[0102] The needle feeding module 2 further comprises a needle feeding ladder 2-10 cooperating with the screw feeding mechanism; a needle feeding ladder frame 2-11 is installed at the bottom of the needle feeding ladder 2-10, and a needle feeding ladder frame bottom plate 2-12 is fixedly connected to the bottom of the needle feeding ladder frame.

[0103] Among them, the needle feeding ladder 2-10 is a conventional transmission ladder disclosed in the prior art, and its main structure includes a chain plate machine and a ladder frame installed on the chain plate machine. The knitting needles are fed into the ladder frame for lifting and transmission.

[0104] Example 5

[0105] like Figure 1-9 As shown, based on the structure of the fourth embodiment, in order to detect the knitting needles, the needle detection module 3 includes a first detection unit and a second detection unit spaced apart on both sides, and the knitting needles are detected through the needle detection module 3.

[0106] Specifically, the first detection unit includes a first camera frame 3-2 arranged at the feeding position of the needle feeding ladder 2-10 (a baffle 3-1 is installed at the bottom of the first camera frame 3-2, and the baffle 3-1 is fixed at the top position of the bottom plate 2-12 of the needle feeding ladder frame, and a working surface is formed by the baffle 3-1), and a first camera 3-3 is installed on the first camera frame 3-2; the first lens 3-6 on the first camera 3-3 detects the knitting needles. Similarly, the second detection unit includes a second camera frame 3-4 arranged at the discharging position of the needle feeding ladder 2-10, and a second camera 3-5 is installed on the second camera frame 3-4, and the second lens 3-7 of the second camera 3-5 performs detection (the second camera 3-5 is arranged at the feeding end position of the belt conveyor mechanism). The above-mentioned detection method is used to realize rapid identification of defective knitting needles, and defective knitting needles and qualified knitting needles are classified and collected by cooperating with the needle collection module 4 described below.

[0107] Example 6

[0109] At the same time, the needle collection module frame 4-15 is fixedly connected with the suspension plates 4-2 spaced apart on the front and rear sides, and the transmission belt 4-1 is located between the suspension plates 4-2 and is flush with the suspension plates 4-2, so as to facilitate the needle to be pushed and slid from the transmission belt 4-1 to the suspension plates 4-2 and finally fall into the needle collection box.

[0110] Specifically, the needle collection module 4 also includes a plurality of pushing structures for pushing the knitting needles from the belt conveyor mechanism to the lower row, and the needle collection module 4 also includes a needle collection box cooperating with the pushing structure, and the pushing structure pushes the knitting needles into the needle collection box in a classified manner.
