Description

Technical Field

[0001] This invention relates to the field of logistics sorting equipment technology, and in particular to a narrow-strip sorting machine for sorting irregularly shaped items and its intelligent control method. Background Technology

[0002] In the field of logistics sorting, narrow belt sorters are widely used in the sorting of goods in industries such as express delivery and e-commerce due to their compact structure and high sorting efficiency. Existing narrow belt sorters are mainly designed for regular standard parts such as cubes and cuboids. Their core relies on parallel narrow conveyor belts to achieve longitudinal transport and lateral sorting of goods, meeting the sorting needs of conventional standard parts.

[0003] However, in actual logistics scenarios, there are a large number of irregularly shaped parts such as round barrels, irregular furniture parts, and irregularly shaped pipes. Due to their irregular shape and tendency to shift their center of gravity, these irregularly shaped parts are prone to rolling, shifting, and jamming when transported on existing narrow-belt sorting machines, resulting in high sorting error rates and frequent equipment failures. To solve the sorting problem of irregularly shaped parts, some manufacturers have optimized the process by adding fixed guards and adjusting the narrow belt spacing. However, fixed guards can only adapt to irregularly shaped parts of specific sizes, have poor versatility, and are prone to friction and collision with the surface of irregularly shaped parts, causing damage to the goods. Adjusting the narrow belt spacing can reduce the risk of jamming, but it cannot solve the core problem of rolling and shifting of irregularly shaped parts, still requiring a lot of manual assistance in positioning, which seriously affects sorting efficiency.

[0004] Meanwhile, the positioning and limiting structures of existing narrow-strip sorting machines are mostly fixed, unable to adaptively adjust the limiting range according to the actual contour of irregularly shaped parts. Furthermore, the fixed limiting height results in insufficient limiting stability for irregularly shaped parts that are tall or have a high center of gravity, making them prone to tipping over during sorting and turning. In addition, the control methods of existing sorting machines lack targeted logic for irregularly shaped part recognition and adaptive limiting, making it difficult to achieve fully automated control of the entire process from detection, positioning, limiting to sorting of irregularly shaped parts, further limiting their application in irregularly shaped part sorting scenarios.

[0005] Therefore, there is an urgent need for a narrow-band sorting machine that can adapt to the contours of irregularly shaped parts, provide stable positioning, ensure accurate sorting, and achieve intelligent control throughout the entire process, in order to solve the problems of low sorting efficiency, poor stability, and insufficient versatility of existing technologies for sorting irregularly shaped parts.

[0006] Therefore, the existing technology of logistics sorting equipment needs further improvement. Summary of the Invention

[0007] The purpose of this invention is to provide a narrow-band sorting machine for sorting irregularly shaped parts and its intelligent control method, so as to realize adaptive contour limiting, stable conveying and accurate sorting of irregularly shaped parts, improve the automation and reliability of sorting irregularly shaped parts, and reduce the cost of manual intervention.

[0008] To achieve the above objectives, the present invention adopts the following solution: A narrow strip sorting machine for sorting irregularly shaped parts includes a material input channel and a sorting channel connected to the material input channel. Multiple narrow strip sorting components are evenly distributed longitudinally on the sorting channel, and a linear array positioning shaft assembly is arranged between two adjacent narrow strip sorting components. The linear array positioning axis assembly includes multiple elastic telescopic positioning axes evenly distributed in the lateral direction; an extended range telescopic positioning axis is provided inside the elastic telescopic positioning axis; a synchronous contraction inclined top structure is provided between the sorting narrow strip assembly and the multiple elastic telescopic positioning axes; an extended range drive structure is provided between the elastic telescopic positioning axis and the extended range telescopic positioning axis; and a height correction inclined guide structure is provided between the sorting channel and the extended range telescopic positioning axis.

[0009] Furthermore, the sorting channel includes a base, on which a longitudinal conveying device is arranged in the longitudinal direction; a plurality of sorting narrow strip components are arranged laterally, and the plurality of sorting narrow strip components are evenly distributed along the longitudinal direction of the longitudinal conveying device.

[0010] Furthermore, the sorting narrow belt assembly includes a connecting frame for connecting a longitudinal conveyor, the connecting frame having two rollers, a narrow conveyor belt connecting the two rollers, and a forward and reverse drive motor for connecting the end of one of the rollers.

[0011] Furthermore, the linear array positioning axis assembly also includes a connecting plate disposed between two adjacent sorting narrow strip assemblies, and a plurality of elastic telescopic positioning axes are evenly distributed on the connecting plate in the lateral direction; The elastic telescopic positioning shaft includes a vertical outer shaft cylinder disposed at the bottom of the connecting plate, and a vertical telescopic positioning shaft is movably disposed inside the vertical outer shaft cylinder. A spring structure for maintaining the vertical telescopic positioning shaft by pressing upward is disposed between the vertical outer shaft cylinder and the vertical telescopic positioning shaft.

[0012] Furthermore, the range-extending telescopic positioning shaft includes a hollow portion disposed in the middle of the vertical telescopic positioning shaft, and the vertical range-extending positioning shaft is movably disposed within the hollow portion.

[0013] Furthermore, the synchronous retractable inclined top structure includes a transverse electric track along the connecting frame, a transverse reset slider is movably disposed on the transverse electric track, a reset drive plate is disposed on the transverse reset slider, a plurality of drive triangular slots are evenly distributed on the reset drive plate in the transverse direction, and a drive longitudinal shaft is disposed at the lower end of the vertical telescopic positioning shaft, the drive longitudinal shaft is movably installed in a corresponding drive triangular slot.

[0014] Furthermore, the range-extending drive structure includes a longitudinal slide rail disposed at the lower end of the vertical telescopic positioning shaft, a longitudinal slider movably disposed within the longitudinal slide rail, a first hinge seat disposed at the lower end of the vertical range-extending positioning shaft, a second hinge seat disposed on the longitudinal slider, and a connecting rod hinged between the first hinge seat and the second hinge seat.

[0015] Furthermore, the height correction inclined guide structure includes a side plate disposed on one side of the vertical outer shaft cylinder, the side plate being provided with an inclined slot, and a correction drive crossbar being disposed in the middle of the connecting rod, the correction drive crossbar being movably installed in the inclined slot.

[0016] Furthermore, the drive triangular slot includes an upper inclined surface for pushing down the drive longitudinal shaft and a lower surface for providing clearance space for the drive longitudinal shaft in its lowest position; The slanted groove is inclined from the outer side of the lower end to the inner side of the upper end.

[0017] An intelligent control method includes the following steps: Step S1, Initialization Control: Control the sorting narrow belt assembly to maintain a uniform longitudinal conveying state, control the synchronous shrinking inclined top structure to be in a locked state, drive multiple elastic telescopic positioning shafts and internal extended telescopic positioning shafts to shrink and reset, so that the top of the elastic telescopic positioning shafts is flush with the upper surface of the narrow conveyor belt of the sorting narrow belt assembly. Step S2, Irregular part detection and unlocking: The visual recognition module and weight detection module at the input end of the sorting channel identify whether the items entering the sorting channel are irregular parts. If they are determined to be irregular parts, an unlocking signal is output to the synchronous shrinking inclined top structure to release the synchronous shrinking inclined top structure from locking the elastic telescopic positioning shaft. Step S3, Elastic Positioning and Extended Range Limiting: The elastic telescopic positioning shaft is pushed upward under the elastic force of the spring structure. The elastic telescopic positioning shaft covered by the lower surface of the irregular part is kept in a contracted state under pressure, while the uncovered elastic telescopic positioning shaft is pushed upward and restricts the outer surface of the irregular part, forming a limiting contour to prevent lateral displacement and rolling during the conveying of irregular items. During the upward pushing process of the synchronous elastic telescopic positioning shaft, the linkage extended range drive structure and the height correction inclined guide structure cooperate to drive the extended range telescopic positioning shaft to push upward relative to the elastic telescopic positioning shaft, strengthening the limiting effect of the irregular part and preventing the irregular part from being deviated or rolled during conveying. Step S4, Sorting Positioning and Reset Trigger: The position of the irregular part is collected in real time by the positioning sensor on the sorting channel. When the irregular part is detected to have reached the preset sorting target point, a shrink reset signal and a sorting trigger signal are output. Step S5, Synchronous contraction and sorting execution: Receive the contraction reset signal, control the synchronous contraction inclined top structure to start, drive all elastic telescopic positioning shafts and extended telescopic positioning shafts to synchronously contract below the upper surface of the narrow conveyor belt, and release the restriction on the irregular parts; Receive the sorting trigger signal, according to the preset sorting target position, control the forward and reverse drive motors of the corresponding sorting narrow belt assembly to start in a directional manner, drive the narrow conveyor belt to move laterally, and move the irregular parts laterally to the target sorting position; Step S6, Sorting Reset: After detecting that the irregularly shaped item has detached from the sorting narrow belt assembly, control the forward and reverse drive motor of the sorting narrow belt assembly to stop and reset to the longitudinal conveying state, and simultaneously control the synchronous shrinking inclined top structure to reset to the locked state, waiting for the next item to be sorted.

[0018] In summary, the advantages of this invention over the prior art are: This invention addresses the shortcomings of existing logistics sorting equipment. Through its structural design, it offers the following advantages: The array of elastic telescopic positioning shafts adaptively adjusts the ejection state according to the actual bottom contour of the irregularly shaped part. The uncovered positioning shafts form a limiting contour that conforms to the outer surface of the irregularly shaped part, restricting its movement from all sides and completely solving the problems of rolling and offset. It eliminates the need for specialized limiting structures designed for specific irregularly shaped parts, making it highly versatile and adaptable to sorting various irregularly shaped parts. The elastic telescopic positioning shafts are nested with extended-range telescopic positioning shafts. Through the linkage of the extended-range drive structure and the height-correcting inclined guide structure, extended ejection is achieved, increasing the limiting height. This is particularly suitable for irregularly shaped parts with a high center of gravity and greater height, preventing them from tipping over during conveying and sorting. The limiting stability is significantly improved compared to existing fixed-height structures. The synchronous retraction inclined top structure, through the cooperation of the drive triangular slot and the drive longitudinal axis, can realize the synchronous retraction and reset of all elastic telescopic positioning axes and extended telescopic positioning axes. The lower plane can provide clearance for positioning axes covered by irregular parts, avoiding collision interference and ensuring that the limit structure can be quickly removed during sorting without affecting the lateral movement of irregular parts, thus improving sorting smoothness. The intelligent control method realizes full automation of irregular part detection, adaptive limit, precise positioning, sorting execution and reset, without the need for manual positioning and intervention, which greatly reduces labor costs and reduces sorting errors caused by manual operation, thereby improving the sorting efficiency and accuracy of irregular parts.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-12 The present invention provides a narrow strip sorting machine for sorting irregularly shaped parts, including a logistics input channel 1 and a sorting channel 2 connected to the logistics input channel 1. Multiple sorting narrow strip components 3 are evenly distributed longitudinally on the sorting channel 2, and a linear array positioning shaft component 40 is arranged between two adjacent sorting narrow strip components 3. The linear array positioning axis assembly 40 includes multiple elastic telescopic positioning axes 5 evenly distributed in the transverse direction; each elastic telescopic positioning axis 5 has a range-extending telescopic positioning axis 6 disposed within it; a synchronous contraction inclined top structure 4 is disposed between the sorting narrow strip assembly 3 and the multiple elastic telescopic positioning axes 5; a range-extending drive structure 7 is disposed between the elastic telescopic positioning axes 5 and the range-extending telescopic positioning axes 6; and a height-correcting inclined guide structure 8 is disposed between the sorting channel 2 and the range-extending telescopic positioning axes 6. Under normal conditions, the multiple elastic telescopic positioning axes 5 maintain a contracted state flush with the upper surface of the sorting narrow strip assembly 3 under the drive of the synchronous contraction inclined top structure 4. When an irregularly shaped product is placed in, the lower surface of the irregularly shaped product covers the upper end of the corresponding elastic telescopic positioning axis 5. At this time, the synchronous contraction inclined top structure 4 is unlocked, and the multiple elastic telescopic positioning axes 5 naturally rise under the action of elastic force, covering the upper end of the product. The elastic telescopic positioning shaft 5 at the bottom of the irregular product cannot be pushed up. The elastic telescopic positioning shaft 5 that is not covered at the bottom of the irregular product is pushed up and used to limit the outer surface of the irregular product, forming a limiting contour to prevent the irregular item from shifting or rolling during the conveying process. At the same time, the elastic telescopic positioning shaft 5 during the upward process will drive the internal extended telescopic positioning shaft 6 to follow and push up synchronously. The extended telescopic positioning shaft 6 will be pushed up by the cooperation of the height correction inclined guide structure 8 and the extended drive structure 7, so that the extended telescopic positioning shaft 6 pushes up a higher distance relative to the elastic telescopic positioning shaft 5. When the irregular product reaches the sorting target point, the synchronous contraction inclined top structure 4 will be activated to retract and reset the multiple elastic telescopic positioning shafts 5 and extended telescopic positioning shafts 6 to below the upper surface of the sorting narrow belt assembly 3, and the sorting narrow belt assembly 3 will be activated to perform lateral conveying to move the irregular item to the target sorting position. Under normal conditions, the synchronous contraction inclined top structure 4 drives the elastic telescopic positioning shaft 5 to contract, making its top end flush with the upper surface of the sorting narrow belt assembly 3. After the irregularly shaped product is placed in, its lower surface covers the corresponding elastic telescopic positioning shaft 5, the synchronous contraction inclined top structure 4 unlocks, and the uncovered elastic telescopic positioning shaft 5 is pushed up under the action of elastic force, forming a limiting contour on the outer surface of the irregularly shaped product to prevent deviation and rolling. When the elastic telescopic positioning shaft 5 is pushed up, it drives the extended telescopic positioning shaft 6 to move synchronously. Through the cooperation of the height correction inclined guide structure 8 and the extended drive structure 7, the extended telescopic positioning shaft 6 is pushed out relative to the elastic telescopic positioning shaft 5, which strengthens the limiting. After the irregularly shaped product reaches the sorting target point, the synchronous contraction inclined top structure 4 drives both to contract to the bottom of the sorting narrow belt assembly 3, and the sorting narrow belt assembly 3 moves laterally to transport the irregularly shaped product to the target position.

When the longitudinal conveying device is in operation, it drives the sorting narrow strip components 3 connected thereto and the irregular products and standard parts carried above to achieve longitudinal uniform speed conveying, providing basic conveying power for subsequent sorting operations.

[0023] The sorting narrow belt assembly 3 of the present invention includes a connecting frame 301 for connecting a longitudinal conveying device. Two rollers 302 are provided on the connecting frame 301, and a narrow conveyor belt 303 is connected between the two rollers 302. A forward and reverse drive motor 304 for connecting the end of one of the rollers 302 is provided on the connecting frame 301. The connecting frame 301 of the sorting narrow belt assembly 3 fixedly supports the two rollers 302, and the narrow conveyor belt 303 is sleeved between the two rollers 302 to form a conveying surface. The forward and reverse drive motor 304 is connected to the end of one of the rollers 302. When the motor rotates forward or reverse, it drives the roller 302 to rotate, thereby driving the narrow conveyor belt 303 to move laterally, so as to realize the sorting of irregular products.

[0024] The linear array positioning shaft assembly 40 of the present invention further includes a connecting plate 4010 disposed between two adjacent sorting narrow strip assemblies 3, and a plurality of elastic telescopic positioning shafts 5 are evenly distributed on the connecting plate 4010 in the transverse direction; The elastic telescopic positioning shaft 5 includes a vertical outer shaft cylinder 501 disposed at the bottom of the connecting plate 4010. A vertical telescopic positioning shaft 502 is movably disposed inside the vertical outer shaft cylinder 501. A spring structure 503 for keeping the vertical telescopic positioning shaft 502 pressed upward is disposed between the vertical outer shaft cylinder 501 and the vertical telescopic positioning shaft 502. The connecting plate 4010 fixes multiple elastic telescopic positioning shafts 5 between adjacent sorting narrow belt assemblies 3. The vertical outer shaft cylinder 501 of the elastic telescopic positioning shaft 5 provides a sliding guide for the vertical telescopic positioning shaft 502. The spring structure 503 continuously applies upward pressure to the vertical telescopic positioning shaft 502, ensuring that after the synchronous contraction inclined top structure 4 is unlocked, the vertical telescopic positioning shaft 502 not covered by the irregular part can quickly rise to form a limit position.

The hollow portion 601 in the middle of the vertical telescopic positioning shaft 502 provides vertical sliding space for the vertical extended range positioning shaft 602, so that the vertical extended range positioning shaft 602 can move synchronously with the vertical telescopic positioning shaft 502. At the same time, it can move up and down relative to the vertical telescopic positioning shaft 502 under the action of the extended range drive structure 7, thereby realizing the extension of the limit height.

[0026] The synchronous retractable inclined top structure 4 of the present invention includes a transverse electric track 401 along the connecting frame 301. A transverse reset slider 402 is movably disposed on the transverse electric track 401. A reset drive plate 403 is disposed on the transverse reset slider 402.

The drive longitudinal shaft 405 is movably installed in a corresponding drive triangular slot 404. The transverse electric track 401 drives the transverse reset slider 402 and the reset drive plate 403 to move laterally. The drive triangular slots 404 on the reset drive plate 403 cooperate with the drive longitudinal shaft 405 at the lower end of the vertical telescopic positioning shaft 502. When the reset drive plate 403 moves laterally, the upper inclined surface 4041 of the drive triangular slot 404 pushes down on the drive longitudinal shaft 405, causing the vertical telescopic positioning shaft 502 to compress the spring structure 503 and retract synchronously, realizing multi-axis unified reset.

[0027] The extended range drive structure 7 of the present invention includes a longitudinal slide rail 701 disposed at the lower end of the vertical telescopic positioning shaft 602, a longitudinal slider 702 movably disposed within the longitudinal slide rail 701, a first hinge seat 703 disposed at the lower end of the vertical extended range positioning shaft 602, a second hinge seat 704 disposed on the longitudinal slider 702, and a connecting rod 705 hinged between the first hinge seat 703 and the second hinge seat 704. When the longitudinal slider 702 moves toward one side of the vertical extended range positioning shaft 602, it pushes the inner end of the connecting rod 705 upward, causing the... The first hinge seat 703 moves upward, enabling the vertical extension positioning shaft 602 to move upward; the longitudinal slider 702 can slide longitudinally along the longitudinal slide rail 701 at the lower end of the vertical telescopic positioning shaft 502; the two ends of the connecting rod 705 are respectively hinged to the vertical extension positioning shaft 602 and the longitudinal slider 702 through the first hinge seat 703 and the second hinge seat 704; when the longitudinal slider 702 moves toward the vertical extension positioning shaft 602, it pushes the inner end of the connecting rod 705 to swing upward, and drives the vertical extension positioning shaft 602 to move upward along the hollow part 601 through the first hinge seat 703, thereby achieving extension limit.

[0029] The driving triangular slot 404 of the present invention includes an upper inclined surface 4041 for pushing down the driving longitudinal shaft 405 and a lower surface 4042 for providing clearance space for the driving longitudinal shaft 405 at the lowest position. The lower surface 4042 is used to prevent the driving triangular slot 404 from colliding with the driving longitudinal shaft 405 at the lowest position when the driving triangular slot 404 moves left and right. The driving longitudinal shaft 405 at the lowest position is the area covered by the lower surface of the irregular product. The corresponding driving longitudinal shaft 405 remains stationary when the driving triangular slot 404 moves laterally. The inclined slot 802 is inclined from the lower outer side to the upper inner side; the upper inclined surface 4041 of the drive triangular slot 404 is used to push down the drive shaft 405 during horizontal movement, causing the vertical telescopic positioning shaft 502 to retract; the lower plane 4042 provides clearance for the drive shaft 405, which is at its lowest position and is covered by the irregular product, to avoid collision with the reset drive plate 403 during horizontal movement, ensuring that the positioning shaft in the area covered by the irregular part is stationary and not disturbed; the inclination angle of the inclined slot 802 guides the sliding of the correction drive crossbar 803, ensuring the stability of the extended range linkage.

If it is determined to be an irregular part, an unlocking signal is output to the synchronous shrinking inclined top structure 4 to release the synchronous shrinking inclined top structure 4 from the lock of the elastic telescopic positioning shaft 5. Step S3, Elastic Positioning and Extended Range Limiting: The elastic telescopic positioning shaft 5 is pushed upward under the elastic force of the spring structure 503. The elastic telescopic positioning shaft 5 covered by the lower surface of the irregular part is kept in a contracted state under pressure, while the uncovered elastic telescopic positioning shaft 5 is pushed upward and restricts the outer surface of the irregular part, forming a limiting contour to prevent lateral displacement and rolling during the conveying of irregular items. During the upward pushing process of the synchronous elastic telescopic positioning shaft 5, the linkage extended range drive structure 7 and the height correction inclined guide structure 8 cooperate to drive the extended range telescopic positioning shaft 6 to push upward relative to the elastic telescopic positioning shaft 5, thereby strengthening the limiting effect of the irregular part and preventing the irregular part from shifting or rolling during conveying. Step S4, Sorting Positioning and Reset Trigger: The position of the irregular part is collected in real time by the positioning sensor on the sorting channel 2.

The intelligent control method of the sortation machine for sorting narrow strips of special-shaped parts according to claim 9, characterized in that, The method comprises the following steps: Step S1, initialization control: control the sorting narrow belt assembly (3) to keep a uniform speed longitudinal conveying state, control the synchronous contraction inclined top structure (4) to be in a locked state, drive the plurality of elastic telescopic positioning shafts (5) and the internal range increasing telescopic positioning shaft (6) to be contracted and reset, and make the top end of the elastic telescopic positioning shaft (5) flush with the upper surface of the narrow conveying belt (303) of the sorting narrow belt assembly (3); Step S2, special-shaped part detection and unlocking: through the visual recognition module and the weight detection module at the input end of the sorting channel (2), whether the article entering the sorting channel (2) is a special-shaped part is identified, if it is determined that the article is a special-shaped part, an unlocking signal is output to the synchronous contraction inclined top structure (4), and the locking of the elastic telescopic positioning shaft (5) by the synchronous contraction inclined top structure (4) is released; Step S3, elastic positioning and range increasing limiting: the elastic telescopic positioning shaft (5) is pushed upward under the elastic force of the spring structure (503), the elastic telescopic positioning shaft (5) covered by the lower surface of the special-shaped part is kept in a contracted state under pressure, the elastic telescopic positioning shaft (5) not covered is pushed upward and limits the outer surface of the special-shaped part, forming a limiting contour to prevent the special-shaped article from moving sideways and rolling during conveying; during the upward pushing of the synchronous elastic telescopic positioning shaft (5), the range increasing drive structure (7) and the height correcting inclined guide structure (8) are cooperated to drive the range increasing telescopic positioning shaft (6) to be pushed upward relative to the elastic telescopic positioning shaft (5), thereby strengthening the limiting effect of the special-shaped part and preventing the special-shaped part from deviating and rolling during conveying; Step S4, sorting positioning and reset triggering: the conveying position of the special-shaped part is collected in real time through the positioning sensor on the sorting channel (2), when it is detected that the special-shaped part reaches a preset sorting target point, a contraction reset signal and a sorting triggering signal are output. Step S5, synchronous contraction and sorting execution: receiving the contraction reset signal, controlling the synchronous contraction inclined roof structure (4) to start, driving all the elastic telescopic positioning shafts (5) and the telescopic positioning shafts (6) to contract synchronously to below the upper surface of the narrow width conveying belt (303), and releasing the limiting of the special-shaped parts; receiving the sorting trigger signal, controlling the forward and reverse drive motor (304) of the corresponding sorting narrow belt assembly (3) to start in a direction according to the preset sorting target position, driving the narrow width conveying belt (303) to side shift, and side shifting the special-shaped parts to the target sorting position; Step S6, sorting reset: after detecting that the special-shaped parts are separated from the sorting narrow belt assembly (3), controlling the forward and reverse drive motor (304) of the sorting narrow belt assembly (3) to stop and reset to the longitudinal conveying state, synchronously controlling the synchronous contraction inclined roof structure (4) to reset to the locking state, and waiting for the next article sorting.
