Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and in particular to an NC sorting module and its control method. Background Technology

[0002] In logistics, e-commerce, food processing, and other fields, automated sorting equipment is a core infrastructure for improving cargo handling efficiency. Among them, NC sorting equipment, with its precise program control capabilities, can automatically classify goods of different specifications and weights. The modular belt transport component, as the core execution unit of the NC sorting equipment, undertakes the important functions of cargo transportation, positioning transmission, and assisting the sorting mechanism in completing cargo turning and diversion.

[0003] In existing modular belt conveyor and sorting equipment, traditional NC modules have shortcomings when sorting goods of different sizes. On the one hand, some equipment's sorting components lack a targeted size adaptation mechanism. Regardless of the size of the goods, related contact wheels and other components are pushed into contact with the modular belt via telescopic parts. This causes unnecessary contact wheels to rub against the modular belt, resulting in unnecessary friction loss and affecting the service life of both the modular belt and the contact wheels. Therefore, it is necessary to design an NC sorting module and its control method.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] This invention provides an NC sorting module and its control method to solve the problem that when traditional NC modules sort goods of different sizes, the lack of a size adaptation mechanism often causes unnecessary friction between the contact wheel and the module belt, resulting in reduced lifespan.

[0006] The present invention adopts the following technical solution: an NC sorting module. It includes a transport mechanism, which includes a support frame with rollers at both ends. Multiple sets of spaced-apart sprockets are fixedly sleeved on the rollers, and a module belt is connected and engaged between the sprockets on the two sets of rollers. The NC sorting mechanism is disposed below the module belt and includes a mounting panel disposed between the two end supports. The mounting panel has multiple sets of contact portions suitable for contacting the module belt and generating friction.

[0007] Furthermore, the contact part includes an eccentric rod disposed at the lower end of the mounting panel. One end of the eccentric rod is fixed with a drive shaft, and the other end of the eccentric rod has a shaped groove. A connector is inserted into the shaped groove. One end of the connector has a shaped end that is adapted to the shaped groove. A movable sleeve is sleeved on the connector. The movable sleeve is embedded in the mounting panel. The surface of the movable sleeve has symmetrically arranged pins. The mounting panel has a through groove adapted to the movable sleeve.

[0008] Furthermore, multiple sets of contact parts are symmetrically distributed along the center line of the mounting panel. The left contact part is defined as the first contact part, and the right contact part is the second contact part. The first contact part has multiple sets of drive shafts at one end that are movably connected to a linkage frame, and the second contact part also has multiple sets of drive shafts at one end that are movably connected to a linkage frame.

[0009] Furthermore, the linkage frame is provided with a first sorting part, which includes a waist-shaped plate fixed on the linkage frame. The waist-shaped plate has a waist groove, and a rotating wheel is provided in the waist groove. The rotating wheel has a central shaft, and a turning rod is provided at one end of the central shaft. A drive shaft is fixed at the eccentric position of the turning rod. An auxiliary plate is supported and fixed on the mounting panel by a support rod. A motor is fixed on the auxiliary plate. A gearbox is provided at one end of the motor. The gearbox has an output shaft connected to the drive shaft. A telescopic component is provided between the two sets of brackets.

[0010] Furthermore, a set of contact parts is divided into three groups based on multiple sets of contact wheels. The contact parts formed by the three sets of contact wheels are defined as contact part one, contact part two, and contact part three in sequence. The contact parts are similar in structure to the contact parts. Each set of contact parts one, two, and three has multiple sets of drive shafts, one end of which is movably connected to a linkage crank arm. The linkage crank arm is provided with a motion part, which is similar in structure to the first sorting part, and is used to drive the movement of each set of contact parts.

[0011] Furthermore, the feeding end of the transport mechanism is equipped with a detection component, which includes a support frame rod connected and fixed between two sets of brackets, a detection part installed on the support frame rod, the detection part adopting a mature industrial vision inspection device in the prior art, and a controller on the bracket.

[0012] Furthermore, the conveying steps include: starting the transport mechanism, driving the motor to rotate the rollers and sprockets via the coupling, driving the module belt to run; placing the goods on the module belt and conveying them to the diversion mechanism;

[0013] Diversion Steps: When goods arrive at the diversion mechanism, the symmetrical inclined pulleys on the support plate guide the goods to both sides of the transport mechanism; the support rollers lift the module belt to prevent sagging and ensure smooth transport.

[0014] Inspection steps: When the goods arrive at the inspection component at the feeding end of the transportation mechanism, the industrial camera in the inspection department takes an image of the goods with the assistance of a ring LED light source, and sends it to the industrial-grade PLC controller via a high-speed interface; the controller extracts the contour features through image recognition, calculates the width of the goods through size conversion, and compares it with the preset small, medium and large size thresholds to determine the size category of the goods;

[0015] Triggering steps: Based on the size category of the goods, the corresponding touch parts are triggered: small size triggers touch part one, medium size triggers touch part one and touch part two in coordination, and large size triggers touch part one, touch part two and touch part three to work synchronously, so that the corresponding contact wheel contacts the module belt;

[0016] Sorting steps: The contact wheel and the module belt generate lateral friction due to the difference in direction and speed, causing the goods to deviate; after sorting, the goods slide towards the guide ramp and slide down the ramp, and the separator separates the goods on different paths, thus completing the sorting.

[0017] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0018] An NC sorting module and its control method are disclosed. By setting multiple sets of contact parts and coordinating with a targeted size adaptation structure, the lack of a size adaptation mechanism in sorting components of traditional equipment is solved. The contact parts of its NC sorting mechanism can selectively contact the module belt according to the size of the goods, avoiding unnecessary friction between the contact wheels and the module belt, reducing friction loss, and effectively extending the service life of the module belt and contact wheels. Simultaneously, the support rollers of the transport mechanism prevent the module belt from sagging due to the weight of the goods, ensuring smooth conveying; the diversion mechanism guides the goods to both sides, optimizing the distribution of goods; and the guide ramps achieve orderly conveying of sorted goods.

[0036] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0037] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example 1

[0038] Reference Figures 1 to 2 As shown, this embodiment of the invention provides an NC sorting module and its control method, including a transport mechanism 1. The transport mechanism 1 includes two sets of supports 11, which are supported and fixed by support legs 12. Rollers (not shown in the figure) are arranged on the two sets of supports 11 near both ends by bearings. A drive motor 14 is fixed on the side of the support 11. The drive motor 14 is fixedly connected to one end of the roller shaft by a coupling. Multiple sets of spaced sprockets 13 are fixedly sleeved on the roller shaft. A module belt (not shown in the figure) is connected and meshed between the sprockets 13 on the two sets of roller shafts. The module belt is used to transport goods. The sprockets 13 and the module belt cooperate with each other. When the roller shaft rotates, the sprockets 13 drive the module belt to rotate, thereby realizing the transport of goods on the module belt.

[0039] A support roller 16 is fixed between the two sets of brackets 11 to support the module belt. The support roller 16 is located below the module belt and plays the role of lifting the module belt. Multiple sets of NC sorting mechanisms 3 are arranged between the two sets of brackets 11 and are arranged at intervals to sort goods. The multiple sets of NC sorting mechanisms 3 are arranged in an orderly manner between the two sets of brackets 11 and can sort the goods transported to the corresponding area.

[0040] Meanwhile, on the two sets of supports 11, on the side that is far apart from each other, there are inclined guide plates 17 that are set downwards. The guide plates 17 are used to receive the goods after they have been sorted by the diversion mechanism 2. The guide plates 17 are inclined downwards, so that the sorted goods can slide down the slope. In addition, there are multiple sets of equally spaced partition plates 18 fixed on the guide plates 17. The partition plates 18 divide the receiving surface of the guide plates 17 into multiple channels, which can separate and guide the goods on different paths.

[0041] Continue to refer to Figures 1 to 2 As shown, a diversion mechanism 2 is provided between the two sets of supports 11. The diversion mechanism 2 is installed at the corresponding position between the two sets of supports 11 as a guiding structure in the initial stage of cargo transportation. The diversion mechanism 2 includes a support plate 21 fixed between the two sets of supports 11, and inclined pulleys 22 are symmetrically arranged on the support plate 21 along the center line. The inclined pulleys 22 symmetrically arranged along the center line face to both sides. When the cargo passes through this point, it will be guided by the symmetrical inclined pulleys 22 facing to both sides and gradually move towards the two sides of the transportation mechanism 1 to prepare the position for subsequent sorting and other operations.

[0042] like Figures 3-5As shown, the NC sorting mechanism 3 includes a mounting panel 31 disposed between two sets of supports 11, and two sets of symmetrically arranged contact portions are provided on the mounting panel 31. Each contact portion includes an eccentric rod 33 disposed at the lower end of the mounting panel 31. The eccentric rod 33 has a right-angle structure, and a drive shaft 34 is fixed to one end of the eccentric rod 33. A groove 331 is formed on the surface of the other end of the eccentric rod 33, and a connector 317 is inserted into the groove 331. The connector 317 has a T-shaped cross-section, and one end of the connector 317 has a shaped end 319 adapted to the groove 331. A movable sleeve 320 is sleeved on the connector 317, and the movable sleeve 320 is embedded in the mounting panel 31. The movable sleeve 320 has symmetrically arranged pins on its surface. A through groove (not shown in the figure) adapted to the movable sleeve 320 is opened on the mounting panel 31. A waist block 318 is integrally provided on the connector 317. A fixing frame 37 is fixedly connected to the connector 317. The bottom surface of the fixing frame 37 has a waist groove adapted to the waist block 318 (not shown in the figure). Two sets of contact wheels 38 are movably arranged on the connector 317. The contact wheels 38 are suitable for contacting the module belt to perform sorting operations on the goods. The contact wheels 38 can move flexibly. At the same time, a rotating shaft 32 is fixed at the center of the waist groove on the bottom surface of the fixing frame 37. One end of the rotating shaft 32 is fixedly inserted into one end of the connector 317.

[0043] In practical applications, the contact wheel 38 is often made of wear-resistant rubber or engineering plastic. When in contact with the module belt, it ensures sufficient friction to drive its own rotation while reducing wear on the module belt. It should be noted that multiple sets of contact points are symmetrically distributed along the centerline of the mounting panel 31, and... Figure 3 From a perspective, the multiple sets of contact portions on the left are defined as the first contact portion, and the contact portion on the right is defined as the second contact portion. The first contact portion has multiple sets of drive shafts 34, one end of which is movably connected to the linkage frame 35. At the same time, the second contact portion also has multiple sets of drive shafts 34, one end of which is movably connected to the linkage frame 35.

[0044] A first sorting section is provided on the linkage frame 35. The first sorting section includes a waist-shaped plate 310 fixed on the linkage frame 35, and the waist-shaped plate 310 has a waist groove 311. A rotating wheel 312 is provided in the waist groove 311. The rotating wheel 312 has a central shaft, and one end of the central shaft has a turning rod 313. A drive shaft 314 is fixed at the eccentric position of the turning rod 313. Meanwhile, an auxiliary plate 39 is supported and fixed on the mounting panel 31 by a support rod 36. A motor 316 is fixed on the auxiliary plate 39. A gearbox 315 is provided at one end of the motor 316. The gearbox 315 has an output shaft connected to the drive shaft 314. The gearbox 315 transmits the power of the motor 316 to the drive shaft 314 through internal gear meshing.

[0045] Furthermore, a telescopic component is provided between the two sets of brackets 11 to drive the NC sorting mechanism 3 to move upward so that the contact wheel 38 contacts the module belt to generate friction. This telescopic component can be a cylinder. In practical applications, the cylinder is powered by compressed air, has a fast response speed, and can control the upward movement distance of the NC sorting mechanism 3 so that the contact wheel 38 and the module belt reach a suitable contact pressure to ensure the friction sorting effect.

[0046] Working principle: First, the transport mechanism 1 is started, and the external power source drives the roller shaft to rotate. The sprocket 13 on the roller shaft rotates accordingly, which in turn drives the module belt to operate. The goods are placed on the module belt and begin to be transported. In the initial stage of goods transport, the goods pass through the diversion mechanism 2. The inclined pulleys 22 on the support plate 21 of the diversion mechanism 2, which are symmetrical along the center line and facing both sides, guide the goods to the two sides of the transport mechanism 1, making the distribution of goods more reasonable. At the same time, the support roller 16 supports the module belt to prevent the module belt from sagging excessively due to the weight of the goods, ensuring the stability of the goods transport process.

[0047] Next, when the goods are transported to the area where the NC sorting mechanism 3 is located, the telescopic part (cylinder) is activated, driving the NC sorting mechanism 3 to move upward, so that the contact wheel 38 on the fixed frame 37 contacts the module belt. At this time, the motor 316 starts, and its power is transmitted and converted through the gearbox 315, and then transmitted to the drive shaft 314 through the output shaft. The drive shaft 314 drives the deflector rod 313 to rotate, which in turn causes the rotating wheel 312 to move in the waist groove 311 of the waist plate 310. Through the linkage frame 35, the drive shaft 34 of the first contact part and the second contact part moves. The drive shaft 34 drives the eccentric rod 33 to rotate, and the rotation of the eccentric rod 33 causes the rotating shaft 32 to rotate, which finally makes the contact wheel 38 on the fixed frame 37 rotate.

[0048] In practical applications, the modular belt continuously transports goods. When the contact wheel 38 rotates, it generates friction with the modular belt, and the rotation direction and speed of the contact wheel 38 differ from those of the modular belt. When the goods reach the contact wheel 38 along with the modular belt, the contact wheel 38 applies a lateral frictional force to the goods, changing the movement state of the goods along the modular belt and causing the goods to deviate in the direction guided by the contact wheel 38. Thus, the contact friction is used to sort the goods and guide them to different directions. Example 2

[0049] In practical applications, the module belt portion that does not contact the goods during sorting of goods of different sizes will experience frictional wear with the upward-moving contact wheel 38. This embodiment solves this problem and improves sorting accuracy through two major innovations: contact portion segmentation and independent drive, and intelligent detection adaptation. Figures 6-7 As shown, to solve this loss problem, this embodiment innovatively adjusts the connection and driving method of the contact parts. Unlike the first embodiment, this embodiment abandons the design of multiple sets of contact wheels 38 linked together in the first embodiment. Instead, it divides a set of contact parts into three groups of contact parts according to the number of contact wheels 38, which are defined as contact part one 71, contact part two 72, and contact part three 73 (similar in structure to the original contact parts). One end of the multiple sets of drive shafts 34 of each group of contact parts is movably connected to the linkage arm 74. The linkage arm 74 allows each part of the contact part to receive power and move independently. The linkage arm 74 is also provided with a moving part similar in structure to the first sorting part, which is used to drive each group of contact parts to operate. At the same time, a telescopic rod with the same number of contact parts is set between the two sets of brackets 11, which can drive the corresponding contact parts to move upward, so that the contact wheel 38 and the module belt reach the appropriate contact pressure and avoid ineffective friction.

[0050] like Figure 2 As shown, in order to detect the width of goods at the initial stage of goods transportation in order to provide data support for subsequent sorting processes, a detection component 6 is provided at the feeding end of the transportation mechanism 1. The detection component 6 includes a support frame rod 61 connected and fixed between two sets of brackets 11, and a detection part 62 provided on the support frame rod 61. The detection part 62 adopts mature industrial vision inspection equipment in the prior art, specifically an industrial camera. When the goods are transported to the bottom of the detection component 6 with the module belt, the industrial camera can take multiple pictures of the goods in a short time.

[0051] The detection unit 62 sends the captured cargo image information to the controller set on the bracket 11 via a high-speed data transmission interface. The controller is usually an industrial-grade PLC. The industrial-grade PLC runs an image recognition algorithm to intelligently analyze the cargo image, extract the contour features of the cargo, and then accurately calculate the width of the cargo through pixel calibration and size conversion. The detection result is compared with a preset cargo width threshold. If the detected width exceeds or falls below the threshold, the corresponding action of the subsequent sorting mechanism can be triggered in time. For example, when the cargo width is suitable for small-sized cargo, the motion unit is triggered to drive the contact wheel 38 of the contact unit to move upward to perform the sorting action.

[0052] Working Principle: After the goods enter the module belt of the transport mechanism 1 and begin to be conveyed, they first pass through the area where the detection component 6 is located. At this time, the detection unit 62 on the support frame 61 is activated, and the industrial camera takes multiple high-speed photos of the moving goods under uniform illumination provided by the ring LED light source, capturing clear images of the goods' outline. This image information is sent to the industrial-grade PLC controller in real time through a high-speed data transmission interface. The controller runs an image recognition algorithm to quickly extract the edge features of the goods, and then accurately calculates the width data of the goods based on the preset pixel-to-actual-size conversion ratio. This data is then compared with the system's preset small, medium, and large size thresholds to determine the size category of the goods, providing an accurate basis for subsequent sorting operations.

[0053] Based on the dimensions of the goods determined by the controller, the system triggers the corresponding touch parts accordingly: for small goods, the controller instructs the telescopic rod corresponding to touch part 71 to activate, pushing touch part 71 upward. Simultaneously, the moving part on the linkage arm 74, following a similar drive logic to the first sorting part, drives the drive shaft 34, eccentric rod 33, and rotating shaft 32 in tandem, causing the contact wheel 38 of touch part 71 to rotate and contact the module belt, generating appropriate friction. Meanwhile, touch parts 72 and 73 remain stationary, and their contact wheels 38 do not contact the module belt, avoiding unnecessary frictional wear. Similarly, medium-sized goods trigger the coordinated action of touch parts 71 and 72, while large goods trigger all three touch parts to work simultaneously, ensuring that the number of contact wheels 38 matches the width of the goods.

[0054] During the contact process between the contact wheel 38 and the module belt, the rotating contact wheel 38, due to the difference in direction or speed between itself and the module belt, applies lateral friction to the goods, forcing the goods to change their linear trajectory along the module belt and deviate in the specified direction. As the module belt continues to convey, the sorted goods gradually leave the area of ​​the NC sorting mechanism 3 and slide towards the guide ramp 17 on the side of the support 11. As they slide down the inclined surface, the separator 18 separates the goods on different paths to prevent mutual interference, ultimately completing the entire sorting process.

[0055] Example 3: The control method for the NC sorting module, in conjunction with the above embodiments of the present invention, is carried out according to the following steps:

[0056] Step 1: Transportation agency initiation and initial cargo delivery

[0057] When the transport mechanism 1 is started, the drive motor 14 rotates, which drives the roller shaft to rotate through the coupling. The sprocket 13 on the roller shaft rotates accordingly, which in turn drives the module belt to start running. The goods are placed on the module belt and transported with the module belt towards the diversion mechanism 2.

[0058] Step Two: Cargo Diversion and Guidance

[0059] When the goods are transported to the diversion mechanism 2, the inclined pulleys 22, which are symmetrical along the center line and facing both sides on the support plate 21, guide the goods to the two sides of the transport mechanism 1, making the distribution of goods more reasonable. At the same time, the support rollers 16 lift the module belt to prevent it from sagging excessively due to the weight of the goods, thus ensuring the smoothness of the transport.

[0060] Step 3: Cargo Dimension Inspection

[0061] As the goods continue to be transported, when they pass the detection component 6 at the inlet of the transport mechanism 1, the industrial camera in the detection unit 62, aided by a ring LED light source, takes multiple photos of the goods to capture their outline images. The image information is sent to the industrial-grade PLC controller via a high-speed data transmission interface. The controller runs an image recognition algorithm to extract the outline features of the goods, calculates the width of the goods through pixel calibration and size conversion, and compares it with preset small, medium, and large size thresholds to determine the size category of the goods.

[0062] Step 4: Triggering the action of the sorting mechanism

[0063] Based on the dimensions of the goods determined by the controller, the corresponding touch (or contact) part is triggered to perform an action:

[0064] If the goods are small, the telescopic rod corresponding to the contact part 71 (or the corresponding contact part) is activated, pushing the contact part 71 to move upward. This causes the moving part on the crank arm 74 to work, driving the drive shaft 34, eccentric rod 33 and rotating shaft 32 to rotate and make the contact wheel 38 of the contact part 71 rotate and contact the module belt.

[0065] If the goods are of medium size, the contact part 1 71 and contact part 2 72 (or the corresponding contact part) will cooperate to operate;

[0066] For large-sized goods, the first contact part 71, the second contact part 72, and the third contact part 73 (or all contact parts) are triggered to work simultaneously to ensure that the number of contact wheels 38 matches the width of the goods.

[0067] Step 5: Goods Sorting and Guiding

[0068] Friction is generated when the contact wheel 38 contacts the module belt. Because the rotation direction and speed of the contact wheel 38 are different from those of the module belt, a lateral friction force is applied to the goods, causing the goods to deflect in the specified direction. After sorting, the goods slide towards the downward-sloping guide plate 17 on the side of the support 11 and slide down the slope. The separator plate 18 separates the goods on different paths, completing the sorting process. Example 4

[0069] In actual use, according to the above embodiment 1, for goods of different sizes, the contact wheels 38 of both sets of second sorting sections 4 need to be pushed to contact the module belt through the telescopic component. Only the contact wheel 38 adapted to the width of the goods needs to be moved upwards, but this results in frictional loss between the module belt, which is not in contact with the goods, and the contact wheel 38. For example... Figures 8-12 As shown, this embodiment differs from Embodiment 1 in that it no longer includes a first sorting section, and the multiple contact sections are divided into three groups of equal quantity; Figure 11 From a perspective, a second sorting section 4 is provided on the three sets of contact parts. The second sorting section 4 includes a connecting frame 41 that is movably connected to one end of multiple sets of active shafts 34 on the three sets of contact parts. The connecting frame 41 is composed of multiple sets of interlaced rods, which can divide the multiple sets of active shafts 34 into three wholes, laying a structural foundation for subsequent synchronous movement.

[0070] Furthermore, a waist-shaped plate 42 is fixed on the connecting frame 41. The waist-shaped plate 42 has a waist groove, and a rotating wheel 43 is movably arranged in the waist groove. The rotating wheel 43 has a central shaft, and a turning rod 44 is fixed at one end of the central shaft. A drive shaft 45 is fixed at the eccentric position of the turning rod 44. At the same time, a support frame 415 is fixed on the mounting panel 31. The drive shaft 45 is movably arranged through the support frame 415, and the support frame 415 provides support and guidance for the drive shaft 45. Wear-resistant bushings are provided at the mating point between the support frame 415 and the drive shaft 45 to reduce wear caused by long-term movement.

[0071] Furthermore, two sets of moving parts are provided on the mounting panel 31 near both sides to accommodate goods of different sizes and to accommodate the movement of a specified number of contact wheels 38. Each moving part includes a right-angle plate 47 fixed on the mounting panel 31 near both ends, and an arched frame 48 is slidably provided on the vertical end of the right-angle plate 47. The connection between the arched frame 48 and the vertical end of the right-angle plate 47 can be understood as follows: sliders are fixed on both end faces of the arched frame 48, and guide rails adapted to the sliding of the sliders are fixed on the right-angle plate 47 to ensure the straightness of the arched frame 48 when it slides up and down.

[0072] A cylinder 49 is fixed on the arch frame 48. The telescopic end of the cylinder 49 passes through the arch frame 48 and is fixed with a push plate 411. A guide rod (not shown in the figure) is fixed on the side of the push plate 411 away from the cylinder 49. The bottom surface of the guide rod is in contact with the horizontal end of the right angle plate 47. At the same time, two sets of guide rods 417 are fixed on the side of the push plate 411 near the cylinder 49. The guide rods 417 are movably connected through the arch frame 48. The guide rods 417 guide the movement of the push plate 411 and prevent the push plate 411 from deflecting under the push of the cylinder 49.

[0073] like Figure 6 As shown, stroke section one 412, stroke section two 413, and stroke section three 414 are fixedly fixed at equal intervals on the side of push plate 411. Stroke section one 412 consists of three sets of racks arranged vertically at equal intervals. Stroke section two 413 consists of two sets of racks arranged vertically at equal intervals. The two sets of racks in stroke section two 413 are symmetrically arranged with the two lower sets of racks in stroke section one 412. Stroke section three 414 consists of one set of racks. The racks in stroke section three 414 are on the same straight line as the lowermost set of racks in stroke section one 412. Meanwhile, a gear 46 suitable for meshing with the racks of the stroke section is fixedly sleeved on drive shaft two 45.

[0074] It should be noted that the stroke section 412 has a vertical distance between the rack near the uppermost end of the three sets of racks and the gear 46. At the same time, the number of teeth on the rack in the stroke section is just enough to make the contact wheel 38 rotate to match the specified sorting angle. Meanwhile, a vertically arranged cylinder 416 is fixed at the horizontal end of the right angle plate 47. A T-shaped block (not shown in the figure) is fixed at one end of the cylinder 416. At the same time, a T-shaped groove is opened at the bottom of the guide rod to accommodate the sliding of the T-shaped block. The cooperation between the T-shaped block and the T-shaped groove not only ensures the guiding of the guide rod sliding, but also transmits the power of the cylinder 416 to drive the arch frame 48 to move up and down.

[0075] In actual use, when the goods to be sorted are small, the first response cylinder 416 drives the arch frame 48 to move upward. At this time, the arch frame 48 simultaneously drives the stroke section 412, stroke section 413, and stroke section 414 to move upward. This makes the rack and gear 46 of the stroke section 412 near the top level on the same horizontal line. Then, the push plate 411 is moved by the first cylinder 49. At this time, only the rack and gear 46 of the stroke section 412 near the top mesh, thereby driving the contact wheel 38 of a set of contact parts to rotate to adapt to the contact module belt to generate friction. In practice, the friction force generated by the contact wheel 38 in contact with the module belt is moderate.

[0076] Similarly, when the goods to be sorted are of medium size, the first response cylinder 416 drives the arch frame 48 to move upward. At this time, the arch frame 48 simultaneously drives the stroke section 1 412, stroke section 2 413, and stroke section 3 414 to move upward. This makes the rack near the middle of stroke section 1 412 and the rack near the upper end of stroke section 2 413 keep on the same horizontal line as the uniform gear 46. Then, the push plate 411 is moved by the first cylinder 49. At this time, only the rack near the middle of stroke section 1 412 and the rack near the upper end of stroke section 2 413 mesh with the uniform gear 46, thereby driving the contact wheels 38 of the two sets of contact sections to rotate to adapt to the contact module belt to generate friction.

[0077] Similarly, when the goods to be sorted are large, the first response cylinder 416 drives the arch frame 48 to move upward. At this time, the arch frame 48 simultaneously drives the stroke section 412, stroke section 413, and stroke section 414 to move upward, so that the rack near the bottom of stroke section 412, the rack near the bottom of stroke section 413, and the rack of stroke section 414 are all on the same horizontal line as the gear 46. Then, the push plate 411 is moved by the first cylinder 49. At this time, the rack near the bottom of stroke section 412, the rack near the bottom of stroke section 413, and the rack of stroke section 414 mesh with the gear 46, thereby driving the contact wheels 38 of the three sets of contact sections to rotate, so as to adapt to the contact module belt to generate friction.

[0078] It should be noted that, similar to Embodiment 2 above, the detection component 6 is used to cooperate with the second sorting unit 4 to drive the contact wheels 38 of a specified number of contact parts to move upward according to the size of the goods to perform sorting operations.

[0079] like Figures 8-9As shown, unlike Embodiment 1 above, the connection between the rotating shaft 32 and the eccentric rod 33 is replaced by an upward moving component 5. That is, an upward moving component 5 is provided on the mounting panel 31. This upward moving component 5 is used to simultaneously rotate the three sets of contact parts and simultaneously perform an upward movement. The upward moving component 5 includes a fixed bushing 51 that passes through and is fixed on the mounting panel 31, and a push shaft 52 that movably passes through the center of the fixed bushing 51. The push shaft 52 passes through one end of the eccentric rod 33, and one end of the push shaft 52 has a pad 53. A torsion spring 54 is sleeved on the push shaft 52. One end is connected to the pad 53, and the other end is connected to the bottom surface of one end of the eccentric rod 33. At the same time, an installation ring 55 is fixedly sleeved on the bottom surface of the fixed frame 37 and the push shaft 52. A contact ball 56 is installed on the side of the installation ring 55. At the same time, a sloped arc block 57 that contacts the contact ball 56 is fixed on the upper surface of the mounting panel 31. Initially, the contact ball 56 is at the lower end of the sloped arc block 57. The contact ball 56 is made of wear-resistant hard alloy material. The surface of the sloped arc block 57 is polished to reduce the friction when the contact ball 56 slides, so that the movement of the upward component 5 is smoother.

[0080] Working Principle: First, after the goods enter the feeding end of the transport mechanism 1, the module belt starts and moves the goods along the conveying direction. At the same time, the detection component 6 at the feeding end starts synchronously. The industrial camera of the detection unit 62 takes multiple high-speed photos of the moving goods under uniform illumination provided by the ring LED light source. Even in scenarios with unstable ambient light, it can capture clear images of the goods' outline. This image information is sent to the industrial-grade PLC controller in real time through a high-speed data transmission interface. The controller runs an image recognition algorithm to extract the edge features of the goods, and then accurately calculates the width of the goods based on a preset pixel-to-actual-size conversion ratio. This width data is then compared with the preset small, medium, and large size thresholds in the system to quickly determine the size category of the goods, providing an accurate basis for triggering the subsequent sorting mechanism's actions.

[0081] Next, based on the dimensions of the goods determined by the controller, the moving part and the upward moving component 5 work together to drive the corresponding number of contact wheels 38 to move:

[0082] For small-sized goods: Cylinder 3 416 starts first, driving the arched frame 48 to move upward along the guide rail of the right-angle plate 47 until the rack near the uppermost end of the stroke section 412 is on the same horizontal line as the gear 46 on the drive shaft 2 45; then cylinder 1 49 starts, pushing the push plate 411 to move. At this time, only the rack of the stroke section 412 meshes with the gear 46. Through the linkage of the drive shaft 2 45, the turning rod 2 44, the rotating wheel 2 43 and other components, the active shaft 34 of a set of contact parts is driven to rotate; at the same time, the upward moving component 5 works synchronously, pushing the shaft 52 to cooperate in the fixed bushing 51. The torsion spring 54 provides the reset tension, and the contact ball 56 on the side of the mounting ring 55 slides along the slope arc block 57, driving the fixed frame 37 and the contact wheel 38 to move upward synchronously, so that the contact wheel 38 contacts the module belt and generates a moderate friction force, providing power for sorting small-sized goods.

[0083] For medium-sized goods: Cylinder 3 416 drives the arched frame 48 to move upward, so that the rack near the middle in stroke section 1 412 and the rack near the upper end in stroke section 2 413 are simultaneously aligned with gear 46; when cylinder 1 49 pushes the push plate 411, these two sets of racks mesh with gear 46 synchronously, and drive the drive shaft 34 of the two sets of contact parts to rotate through the transmission mechanism. The upward moving component 5 synchronously drives the two sets of contact wheels 38 to move upward and contact the module belt, generating a frictional force suitable for medium-sized goods.

[0084] For large-sized goods: Cylinder 3 416 drives the arched frame 48 to move up to the rack near the bottom of the first stroke section 412, the rack near the bottom of the second stroke section 413, and the rack of the third stroke section 414, all of which are aligned with the gear 46; after cylinder 1 49 pushes the push plate 411, the three sets of racks and gears 46 mesh simultaneously, driving the drive shaft 34 of the three sets of contact sections to rotate, and the upward moving component 5 drives the three sets of contact wheels 38 to move up synchronously and contact the module belt, forming a frictional force that meets the sorting requirements of large-sized goods.

[0085] During the contact process between the contact wheel 38 and the module belt, the contact wheel 38 will exert a lateral friction force on the goods due to the difference in rotation direction or speed between the contact wheel 38 and the module belt. This friction force breaks the linear motion of the goods along the module belt and guides the goods to deviate in the preset sorting direction, thereby realizing the path diversion of goods of different sizes.

[0086] Finally, the sorted goods are conveyed along the modular belt to the guide ramps 17 on both sides of the transport mechanism 1, and slide down the inclined surface naturally. Multiple sets of partitions 18 on the guide ramps 17 divide the receiving surface into independent channels, which physically separates the goods on different diversion paths, preventing the goods from colliding, stacking or shifting during the descent, and ensuring that each batch of goods can smoothly enter the subsequent transport stage along the designated channel, thus completing the closed-loop process of modular belt transport and NC sorting.
