Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and further to a streamlined quality inspection and bagging device and method for tubular products. Background Technology

[0002] After production, tubular products such as capped tubes require multiple quality inspections, mainly including: inspection of the outer diameter, length, adhesive layer thickness, and surface condition (such as dents, damage, pinholes, and bubbles) of the capped end face; tail defects such as cracks and damage; and defects in the total length and shape of the sides. Due to the large number of inspection items, traditional manual inspection methods involve repetitive operations such as tube picking, stacking, head inspection, tail inspection, end face inspection, defective product sorting, weighing, and bagging. This is time-consuming, labor-intensive, inefficient, and prone to missed inspections or misjudgments due to fatigue. Furthermore, the individual weight variations of capped tubes and similar tubular products necessitate periodic counting and weighing to ensure accurate bagging, further increasing the complexity and labor intensity of manual operations.

[0003] Therefore, there is an urgent need for a streamlined quality inspection and bagging device and method for tubular products to solve the above problems. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention aims to provide a streamlined quality inspection and bagging device and method for tubular products, which realizes the function of rapid, continuous, and automatic batch quality inspection of tubular products. It has the effects of automatic feeding and streamlined quality inspection and bagging, and can also have a certain universal quality inspection effect for plastic tubes with incomplete standard shapes. It can better replace manual inspection and free up relevant quality inspection labor.

[0005] To achieve the above objectives, the present invention provides a streamlined quality inspection and bagging device for tubular products, comprising: The feeding mechanism is used to output tubular products in a single row. The feeding mechanism includes a storage tank, a linear vibrator, a centrifugal disc, and a differential feeding mechanism. The differential feeding mechanism is equipped with a polyurethane wheel with adjustable clamping force to output tubular products one by one. A differential conveying mechanism is located behind the feeding mechanism. The conveying speed of the differential conveying mechanism is higher than that of the differential distributing mechanism. It is used to accelerate the extraction of tubular products and form uniform intervals. A reversing mechanism, located after the differential conveying mechanism, is used to uniformly adjust the tubular products so that the head faces forward. An inspection and conveying mechanism is used to receive and convey tubular products that have completed reversal. The inspection and conveying mechanism includes a V-groove synchronous belt, multiple optical inspection components and an air-blowing rejection component. The optical inspection components include at least a vision sensor for detecting the side dimensions and shape, tail defects and head end dimensions and surface defects of the product. The air-blowing rejection component is used to reject defective products based on the inspection results. The material sorting and bagging mechanism is located at the end of the detection and conveying mechanism and is used to count and bag the tubular products that have passed the inspection.

[0006] In some embodiments, the feeding mechanism further includes: A material level sensor is installed at the centrifugal disc to automatically control the start and stop of the linear vibrator according to the material level height. The centrifugal disc is a double-layer centrifugal disc driven by dual motors, and the rotation speed of its inner and outer layers can be visually and independently adjusted.

[0007] In some embodiments, the differential conveying mechanism further includes: A roller assembly, comprising rollers and a flattening rod, is used to limit and press down tubular products during the conveying process to prevent the products from detaching from the conveying platform.

[0008] In some embodiments, the reversing mechanism includes: Hook rod, used to hook the tail of tubular products to achieve rotational reversal; The horizontal conveyor assembly is used to prevent tubular products from being hooked by the hook rod when reversing direction by using a micro-squeezing contact method. The magnetic reset assembly includes a neodymium iron boron ring magnet and a damper. Through the attraction and repulsion between the magnetic poles, combined with the damping force provided by the damper, the hook rod is reset when it is hit by the head, and rotates to the next station when it hooks the tail, thereby achieving a uniform forward-facing orientation for all products.

[0009] In some embodiments, the horizontal conveying assembly includes: slide rail; A slider is disposed on the slide rail; A drive motor, connected to the slider, is used to drive the slider to reciprocate along the axial direction of the slide rail; Two synchronous belt assemblies arranged at relative intervals, with their synchronous belts driven by synchronous pulleys driven by servo motors to rotate cyclically, achieve clamping and conveying of tubular products through the synchronous operation of the two synchronous belts; At least one of the timing belt components is fixedly mounted on the slider, so that the clamping distance between the two timing belt components can be visually adjusted and fixed by moving the slider, in order to adapt to tubular products of different diameters and achieve micro-extrusion contact.

[0010] In some embodiments, the detection and conveying mechanism further includes: An air-blowing and material-guiding assembly is located at the connection transition between the reversing mechanism and the detection and conveying mechanism. It assists and guides the tubular product smoothly from the reversing mechanism into the V-groove synchronous belt through directional airflow. The inlet tube positioning assembly includes an inlet tube guide sleeve assembly and a tube alignment plate; the inlet tube guide sleeve assembly and the tube alignment plate are arranged sequentially along the conveying direction, and both are provided with an upward convex structure; during the conveying process, the tail of the tubular product first contacts and is limited by the upward convex structure of the inlet tube guide sleeve assembly, and the head then contacts and is limited by the upward convex structure of the tube alignment plate. Through the sequential bidirectional limitation of the head and tail, the tubular product is accurately positioned before inspection.

[0011] In some embodiments, the detection and conveying mechanism further includes: The conveyor belt position sensing component includes a through-beam sensor, which generates a corresponding position pulse signal by detecting the periodic changes in the concave and convex structure of the V-groove synchronous belt during operation, thereby achieving precise real-time positioning of each carrying station on the V-groove synchronous belt.

[0012] In some embodiments, the optical detection component includes: The upper optical inspection component has a lens position and angle that can be adjusted with multiple degrees of freedom to acquire side images of tubular products in order to detect the outer diameter of the head, the outer diameter of the tail, the total length of the product, and shape defects. The tail optical inspection component has a lens position and angle that can be adjusted with multiple degrees of freedom to acquire images of the tail end face of tubular products in order to detect the inner and outer diameters, cracks and damage defects of the tail. The end-effector optical inspection component has a lens position and angle that can be adjusted with multiple degrees of freedom and is equipped with a strong light source to acquire images of the product head end face. By analyzing abnormal light transmission areas in the image caused by insufficient glue thickness, it can detect defects such as outer diameter, perforation, damage, pores and insufficient glue thickness on the head end face.

[0013] In some embodiments, the dispensing and bagging mechanism includes: The lead screw module is used to drive the actuator to move and position in multiple positions; The material distribution hopper is connected to the power output end of the lead screw module. The top of the material distribution hopper has a cut-out structure to form multiple independent receiving compartments. The receiving space of each compartment is larger than the discharge port cross-section of the detection and conveying mechanism. A bag-feeding rod is installed below the dispensing hopper to pre-feed packaging bags, receive qualified products falling from the dispensing hopper compartment, and complete automatic bagging.

[0014] In some embodiments, another method of the present invention using the tubular product automated quality inspection and bagging apparatus as described in any one of the above embodiments includes the following steps: The tubular products are output in a single row through the feeding mechanism, and the products are separated into individual strands by the polyurethane wheel with adjustable clamping force in the differential feeding mechanism. A differential conveying mechanism with a conveying speed higher than the differential material distribution mechanism accelerates the extraction of single tubular products and forms uniform intervals. The reversing mechanism is used to uniformly adjust the tubular products so that the head faces forward. The tubular products that have completed the reversal are conveyed by the inspection and conveying mechanism with V-groove synchronous belt. Multiple optical inspection components are used to visually inspect the side dimensions and shape, tail defects and head end face dimensions and surface defects of the products. Based on the inspection results, the defective products are rejected by the air blowing rejection component. At the end of the inspection and conveying mechanism, the tubular products that have passed the inspection are counted, and then automatically bagged and packaged by the material sorting and bagging mechanism.

[0015] Compared with the prior art, the tubular product automated quality inspection and bagging device and method provided by the present invention have the following advantages: This invention can stably, continuously, and efficiently complete the quality inspection and packaging of tubular products such as capped tubes, effectively solving the problems of low efficiency, high labor intensity, and poor consistency of traditional manual inspection methods. The close connection and coordinated operation between the various mechanisms not only improve the accuracy of quality inspection, but also have good product size adaptability. While reducing labor costs, it improves the automation level of the production line and the overall quality control capability. Attached Figure Description

Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0022] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] In one embodiment, refer to the appendix to the specification. Figure 1 The present invention provides a streamlined quality inspection and bagging device for tubular products, comprising: a feeding mechanism 2 for outputting tubular products in single rows, the feeding mechanism 2 including a storage tank 21, a linear vibrator 22, a centrifugal disc 23, and a differential speed dispensing mechanism 24, the differential speed dispensing mechanism 24 being equipped with an adjustable pressure polyurethane wheel 242 to output tubular products one by one; a differential speed conveying mechanism 3, located behind the feeding mechanism 2, the conveying speed of the differential speed conveying mechanism 3 being higher than that of the differential speed dispensing mechanism 24, for accelerating the extraction of tubular products and forming uniform intervals; and a reversing mechanism 4, located after the differential speed conveying mechanism 3. The device is used to uniformly adjust tubular products so that the head faces forward; the inspection and conveying mechanism 5 is used to receive and convey the tubular products that have completed the reversal. The inspection and conveying mechanism 5 includes a V-groove synchronous belt 51, multiple optical inspection components and an air-blowing rejection component 55. The optical inspection components include at least a vision sensor for detecting the side dimensions and shape of the product, tail defects and head end dimensions and surface defects. The air-blowing rejection component 55 is used to reject defective products according to the inspection results; the material sorting and bagging mechanism 6 is set at the end of the inspection and conveying mechanism 5 and is used to count and bag the tubular products that have passed the inspection.

[0025] In this embodiment, the quality inspection and packaging of tubular products such as capped tubes can be completed stably, continuously and efficiently, effectively solving the problems of low efficiency, high labor intensity and poor consistency of traditional manual inspection methods; the close connection and coordinated operation between the various mechanisms not only improve the accuracy of quality inspection, but also have good product size adaptability, reducing labor costs while improving the automation level of the production line and the overall quality control capability.

[0026] In one embodiment, refer to the appendix to the specification. Figure 1 The support frame 1 serves as the overall installation platform for the device. It is equipped with casters at the bottom for easy movement and can also be fitted with lifting feet for leveling. A ladder 11 is provided on the side of the support frame 1 for convenient material storage.

[0027] Reference manual attached Figure 2 The material storage tank 21 of the feeding mechanism 2 is large enough to allow for a relatively long feeding time (more than 2 hours) with a single filling. The tubular products in the storage tank 21 are conveyed to the centrifugal disc 23 via the linear vibrator 22, where the centrifugal disc 23 automatically feeds the products. The centrifugal disc 23 is a double-layer centrifugal disc driven by dual motors, and the rotation speed of its inner and outer layers can be visually and independently adjusted. The inner layer speed can be adjusted to be faster for centrifugal rotation and straightening of the material, while the outer layer speed can be adjusted to be slower for single-piece discharge. A material level sensor is also installed at the centrifugal disc 23 to automatically control the start and stop of the linear vibrator based on the material level. When the material level is high, the linear vibrator 22 stops feeding, and when the material level is low, the linear vibrator 22 starts feeding.

[0028] Reference manual attached Figure 3 The differential feeding mechanism 24 includes two differential feeding motors 241, two polyurethane wheels 242, a mounting adjustment plate 243, and two differential feeding bearings 244. The two differential feeding bearings 244 are spaced apart on the mounting adjustment plate 243. The drive shafts of the two differential feeding motors 241 pass through the corresponding differential feeding bearings 244 and are connected to the corresponding polyurethane wheels 242. The clamping degree of the polyurethane wheels 242 can be adjusted to accommodate the separation and feeding of capped tube products with varying outer diameters or irregular shapes. The differential feeding motors 241 rotate automatically, separating the capped tube products one by one. Because the capped tube products have different sizes, the smaller end may insert into the larger end, causing two or more products to be connected in series and discharged simultaneously. Therefore, the polyurethane wheels 242 of this differential feeding mechanism 24 can make just the right contact with a single product, preventing multiple products from being discharged simultaneously. Combined with the faster differential conveying mechanism 3 behind it, the effect of feeding products one by one can be achieved.

[0029] Reference manual attached Figure 4 , Figure 5The differential conveying mechanism 3 includes a conveyor belt 31 with an adjustable conveying speed. Its conveying speed is set faster than the differential material separating mechanism 24, allowing the separated products to be drawn out one by one. Since the conveyed products are tubular, baffle structures can be installed on both sides of the upper part of the conveyor belt 31 to prevent the tubular products from rolling off the conveyor belt.

[0030] Reference manual attached Figure 6 The differential conveying mechanism 3 also includes a roller assembly 32, which comprises a roller mounting plate 321, a roller shaft 322, a roller 323, and a flattening rod 324. The roller mounting plate 321 is fixed to one side of the conveyor belt 31, the roller shaft 322 is mounted on the roller mounting plate 321, the roller 323 is mounted on the roller shaft 322, and the flattening rod 324 is located below the roller 323. The differential conveying mechanism 3 is located behind the reversing mechanism 4. The roller 232 and the flattening rod 324 can limit and press down the capped tube products that are rapidly reversing, preventing the products from being thrown off the conveyor belt 31.

[0031] Reference manual attached Figure 7 The reversing mechanism 4 includes: a reversing mounting frame 41, a reversing shaft 42, a hook rod 43, a damper 44, and a magnetic reset assembly 45. The reversing mounting frame 41 is fixedly mounted on the bracket 1. The reversing shaft 42 is rotatably mounted on the reversing mounting frame 41 via bearings. The hook rod 43 is mounted on one end of the reversing shaft 42 and is used to hook the tail of the tubular product to achieve rotational reversal. The damper 44 is mounted on the reversing mounting frame 41 and located on one side of the hook rod 43. The magnetic reset assembly 45 is mounted on the other end of the reversing shaft 42. The magnetic reset assembly 45 includes a neodymium iron boron ring magnet. Through the attraction and repulsion between the magnetic poles, combined with the damping force provided by the damper 44, the hook rod 43 is reset when it is hit by a head collision and rotates to the next station when it hooks the tail, thereby achieving a unified forward-facing direction for all products. The hook rod 43 can hook the tail of the capped tube for reversal, while the head of the capped tube will not be hooked, ensuring that all capped tubes are arranged with their heads facing forward. The magnetic strength of the magnetic reset component 45 can be adjusted by the distance between them, and the distribution angle of the annular magnets can also be adjusted. This allows the hook rod 43 to rotate 60 degrees every time it passes the head or tail of a capped tube. When the head hits, it swings slightly without rotating, then passes through the middle part where the magnetic poles repel each other, causing it to return to the 0-degree position where the magnetic poles attract each other. When the tail of the hook rod rotates past the middle part where the magnetic poles repel each other, it rotates again to the 60-degree position where the magnetic poles attract each other. The damper 44 can adjust the damping force, providing damping so that the hook rod 43 can quickly return to a calm state or a slightly swinging state. This cycle repeats, with the head hitting the tube, swinging slightly, returning to 0 degrees, and the tail of the hook rod rotating 60 degrees for reversal, thus creating a continuous rotation and reversal cycle.

[0032] Reference manual attached Figure 8The horizontal conveying assembly 46 is used to prevent tubular products from being pulled away by the hook rod 43 during reversal by using a micro-compression contact method. The horizontal conveying assembly 46 includes: a slide rail 461, a slider 462, a drive motor 463, and two synchronous belt assemblies 464. The slide rail 461 is mounted on the bracket 1 via a frame, and the slider 462 is disposed on the slide rail 461. The drive motor 463 is connected to the slider 462 and is used to drive the slider 462 to reciprocate along the axis of the slide rail 461. The two synchronous belt assemblies 464 are arranged relatively apart, and their synchronous belts 4643 are driven by the synchronous pulley 4642 driven by the servo motor 4641 to rotate cyclically. The synchronous operation of the synchronous belts on both sides achieves the clamping and conveying of the tubular products. At least one synchronous belt assembly 464 is fixedly mounted on the slider 462, so that the clamping distance between the two synchronous belt assemblies 464 can be visually adjusted and fixed by the movement of the slider 462 to accommodate tubular products of different diameters and achieve micro-compression contact.

[0033] Reference manual attached Figure 9 , Figure 11 The V-groove synchronous belt 51 is perpendicular to the conveyor belt 31. An air-blowing and material-guiding assembly 56 is installed at the connection between the V-groove synchronous belt 51 and the conveyor belt 31. This assembly uses directional airflow to assist and guide the tubular product smoothly from the conveyor belt 31 into the V-groove synchronous belt 51. The V-groove synchronous belt 51 can accommodate a certain range of pipe diameter changes and solve the clamping problem of deformed and non-rounded plastic pipe products. The inlet positioning assembly 57 includes an inlet guide sleeve assembly and a pipe alignment plate. The inlet guide sleeve assembly and the pipe alignment plate are arranged sequentially along the conveying direction, and both have an upwardly protruding structure. During the conveying process, the tail of the tubular product first contacts and is limited by the upwardly protruding structure of the inlet guide sleeve assembly, and its head subsequently contacts and is limited by the upwardly protruding structure of the pipe alignment plate. Through the sequential bidirectional limiting of the head and tail, precise positioning of the tubular product before inspection is achieved. The inlet guide sleeve assembly serves as a transitional inlet structure between the reversing conveying system and the inspection conveying system. After the capped pipe product enters this structure, it is carried out by the inspection conveying mechanism, thus repeating the cycle. The inspection and conveying mechanism 5 also includes a conveyor belt position sensing component, which includes a through-beam sensor. This sensor detects the periodic changes in the concave and convex structure of the V-groove synchronous belt 51 during operation, generating corresponding position pulse signals to locate the specific position of each V-groove. After one revolution, the position is reset to zero, allowing for station reuse. Defective products are removed via an air-blowing rejection component 55, moving them from the defective product unloading channel into the defective product unloading frame. A product sensing component is installed on the V-groove synchronous belt 51; only tubular products marked at this location are counted and inspected, preventing counting and inspection at empty stations. Furthermore, optical inspection mechanisms can be added to both sides of the inspection and conveying mechanism 5. This type of end-face + side-side inspection method is perfectly suited for the coverage inspection of capped tube products.

[0034] Reference manual attached Figure 10 The optical inspection components include: an upper optical inspection component 52, a tail optical inspection component 53, and an end optical inspection component 54. The upper optical inspection component 52 can adjust the lens back and forth, up and down, and rotate to inspect the outer diameter of the cap head (distance between the two straight lines on both sides of the head), the outer diameter of the tail (distance between the two straight lines on both sides of the tail), the total length of the cap tube, and non-standard shapes (non-standard head shape, no head, folds, and damage, etc.) of the cap tube. The tail optical inspection component 53 can adjust the lens back and forth, up and down, and rotate to inspect the inner and outer diameters of the tail of the cap tube (for relatively standard products with minor deformation), and cracks and damage at the tail. ⑤ The end optical inspection component 54 can adjust the lens back and forth, up and down, and rotate to inspect the outer diameter of the cap head of the cap tube product (it can detect products that are not perfectly round, and measure the approximate diameter by taking the average value of similar ellipses), perforation of the cap head end face, damage and air holes of the cap head end face, and light transmission caused by insufficient glue thickness of the cap head end face: it uses strong light to detect white area pixels to detect problems such as insufficient thickness exceeding the standard.

[0035] Reference manual attached Figure 9 The material dispensing and bagging mechanism 6 includes: a screw module 61, a dispensing hopper 62, bag-feeding rods 63, and a bag-supporting platform 64. The screw module 61 drives the actuators to move and position at multiple stations. The dispensing hopper 62 is connected to the power output end of the screw module 61. The top of the dispensing hopper 62 has a cut-out structure to form multiple independent receiving compartments. The receiving space of each compartment is larger than the discharge port cross-section of the detection and conveying mechanism 5. Multiple bag-feeding rods 63 are spaced apart below the dispensing hopper 62 for pre-feeding packaging bags, receiving qualified products falling from the compartments of the dispensing hopper, and completing automatic bagging. A movable bag-supporting platform 64 is provided below the bag-feeding rods 63 to support the packaging bags.

[0036] The tubular product automated quality inspection and bagging device also includes a control mechanism, which includes a touch screen and a PLC, servo controller, solenoid valve and vision inspection controller integrated inside the equipment, used to set parameters, control motion and monitor status of each actuator of the equipment.

[0037] The purpose of this automated quality inspection and bagging device for tubular products is to solve the problems of time-consuming, labor-intensive, and difficult manual inspection of capped tube products. This device can automatically feed and discharge materials, ensure unidirectional material flow, automatically detect and reject defective products, and perform bagging and packaging. It boasts the advantages of stable and reliable operation, achieving automation and streamlined product quality inspection, and solving a series of similar quality inspection and bagging problems for capped tube products.
