[0012] The present invention also provides a circular tilting sorting device, including a support guide rail, the tilting sorting units, a motor assembly, a pack unloader, and a mechanical reset unit. The support guide rail is circular, and multiple tilting sorting units are placed end-to-end on the upper side of the support guide rail via a first connector and a second connector. The motor assembly is arranged at intervals along the support guide rail and is located below it, for driving the push plate and the tilting sorting units forward.

[0035] This invention discloses a tilting sorting unit, including a frame 11, a tray 12, a vertical plate 13, and a tilting assembly. The tray 12 is made of food-grade PP material and is mounted above the frame 11 via the vertical plate 13. The tilting assembly connects both the vertical plate 13 and the tray 12, allowing the tray 12 to be adjusted between three working positions—horizontal, lateral, and tilting—under external force interference. The tilting sorting unit 1 travels on an external guide rail via rollers mounted on the frame 11. The overall structure is as follows (see reference). Figures 1 to 4 :

[0036] The first connecting frame 111 and the second connecting frame 112 are respectively fixed to the head and tail ends of the frame 11 by bolts. The first connecting frame 111 extends from the head of the frame 11 and a first connecting member 113 is fixed at the front end. The second connecting frame 112 is perpendicular to the frame 11 and has a second connecting member 114 that can be hinged to the first connecting member 113 in its middle. In this embodiment, the first connecting member 113 is a fisheye connector and the second connecting member 114 is a pin that can pass through the fisheye connector. The pin is arranged vertically to realize the connection of multiple tilting sorting units 1 end to end.

[0037] A thrust plate 15 is bolted to the lower part of the frame 11, and the thrust plate 15 is arranged vertically along the length of the frame 11. A second connecting frame 112 connected to the frame 11 has wheels 115 mounted symmetrically at both ends on its side facing the rear end of the frame 11. The rotation axis of the wheels 115 is set perpendicular to the vertical plane where the thrust plate 15 is located, meaning the rotation direction of the wheels 115 is spatially parallel to the arrangement direction of the thrust plate 15, ensuring that the rolling trajectory of the wheels 115 is consistent with the guiding direction of the thrust plate 15. Simultaneously, two limiting wheels 116 are fixedly installed at the bottom of the second connecting frame 112. These two limiting wheels 116 are symmetrically distributed with the middle of the second connecting frame 112 as the center of symmetry, and from the installation position, the limiting wheels 116 are closer to the middle area of ​​the second connecting frame 112 than the wheels 115, forming a compact wheel arrangement. The rotation axis of the limiting wheel 116 is set to be perpendicular to the horizontal plane. This arrangement makes the limiting wheel 116, the thrust plate 15, and the traveling wheel 115 spatially perpendicular, and the force direction and movement trajectory of the three are coordinated with each other.

[0038] Based on the specific installation positions, distribution patterns, and axial directions of the aforementioned traveling wheels 115 and limiting wheels 116, the traveling wheels 115 are ultimately positioned on both sides above the tail end of the thrust plate 15, and the limiting wheels 116 are positioned on both sides slightly above the tail end of the thrust plate 15. The traveling wheels 115 maintain close contact with the top plane of the external guide rail to achieve support and travel functions, while the limiting wheels 116 are in close contact with the inner surface of the external guide rail to provide limiting and guiding functions, ensuring the stable movement of the tilting sorting unit 1 along the external guide rail. A schematic diagram of the cooperation between the tilting sorting unit 1 and the external guide rail can be found in the schematic diagram of the cooperation between the sorting unit 1 and the bearing guide rail 2 in the annular tilting sorting equipment. Figure 6 .

[0039] By connecting the end-to-end of the frame 11 of the tilting sorting unit 1 and optimizing the installation position of the rollers, the sorting unit 1 ultimately achieves the function of stable movement along the external guide rail with only two traveling wheels 115 and two limiting wheels 116. Compared with the traditional design of the prior art, which requires the independent installation of traveling wheels 115 and limiting wheels 116 at the front and rear ends respectively, the present invention significantly reduces the number of roller consumables used, and eliminates the redundant installation structure of independent wheel sets at both ends, making the mechanical structure of the entire sorting unit 1 more streamlined and compact, which not only reduces material costs, but also reduces the structural space occupied.

[0040] Meanwhile, the present invention innovatively integrates the traveling wheel 115 and the limiting wheel 116 on the same connecting frame to form a modular wheel assembly structure. When the rollers are worn or malfunction and need to be repaired or replaced, there is no need to disassemble the wheel sets at the front and rear ends separately. The entire connecting frame can be disassembled and assembled simultaneously, which significantly shortens the maintenance time, greatly improves the efficiency of equipment maintenance and component replacement, and further enhances the overall operational reliability and ease of use of the tilting sorting unit 1.

[0041] Upright plates 13 are fixed to the upper sides of both ends of the frame 11, with the two upright plates 13 arranged opposite each other. The tilting assembly includes a rotating frame 141, a pressure plate 142, a positioning rod 143, and a positioning clamping plate 144. The two ends of the positioning rod 143 are respectively fixed to the two upright plates 13, and are arranged horizontally along the length of the frame 11, that is, the positioning rod 143 is horizontally fixed between the two upright plates 13. The rotating frame 141 is fixed to the bottom of the pallet 12, and an elastic damper 145 is provided through the rotating frame 141. The elastic damper 145 can be a hydraulic buffer to buffer the tilting impact of the pallet 12 and the rotating frame 141 under external force interference. The rotating frame 141 has two pairs of opposite sides, one pair of opposite sides is hinged to the upright plate 13, and the other pair of opposite sides is hinged to the pressure plate 142 below. Specifically:

[0042] The front and rear sides of the rotating frame 141 are each connected to a corresponding bearing seat mounted on the upright plate 13 via a coaxial rotating shaft 146, ensuring that the rotating frame 141 can rotate flexibly around the rotating shaft 146. The rotating shaft 146 is installed directly above the frame 11, and its axis is strictly parallel to the length direction of the frame 11, forming a stable mechanical support structure. Thanks to this rotating shaft 146, the tray 12 fixed on the rotating frame 141 can rotate back and forth in both directions relative to the vertical plane where the frame 11 is located, with the rotating shaft 146 as the center.

[0043] The pressure plate 142 is located below the rotating frame 141 and above the positioning rod 143. Its overall structure is H-shaped, including power plates on the left and right sides and a positioning plate 142c in the middle. The left and right sides of the rotating frame 141 are connected to the power plates on the left and right sides of the pressure plate 142 via a rotating shaft, which is also located near the rear of both. A positioning plate 144 is fixed to the positioning plate 142c in the middle of the pressure plate 142. The positioning plate 144 has a slot below it that matches the upper contour of the positioning rod 143, and the slot has an arc-shaped design on both sides. A compression spring 147 is provided between the rotating frame 141 and the pressure plate 142. The two ends of the compression spring 147 abut against the lower surface of the rotating frame 141 and the upper surface of the positioning plate 142c, respectively. Without external interference, the compression spring 147 applies pressure to the pressure plate 142, causing the positioning plate 144 and the positioning rod 143 to contact, restricting the rotation of the tray 12 and thus positioning the tray 12.

[0044] The power plate includes a first inclined plane 142a and a second inclined plane 142b. The angle of inclination of the first inclined plane 142a to the horizontal plane is greater than that of the second inclined plane 142b to the horizontal plane. The first inclined plane 142a is located on the front side of the pressure plate 142. The overall structure of the power plate has a trend of descending from high to low and then down again. During the stable movement of the tilting sorting unit 1 along the external track, if it encounters an external obstacle, the pressure plate 142 will act as the first contact point to contact the external force, and will cause the positioning plate 144 to disengage from the positioning rod 143 to achieve disengagement. For a schematic diagram of the situation where the pressure plate 142 is subjected to interference external force, please refer to the schematic diagram of the cooperation between the sorting unit 1 and the unloading device 4 in the annular tilting sorting equipment. Figure 9 At the same time, the force exerted on the pressure plate 142 is effectively transmitted through the compression spring 147 connected to it, and accurately transmitted to the rotating frame 141, which in turn drives the rotating frame 141 to drive the pallet 12 carrying the material on it to rotate smoothly around the rotating axis 146, thus completing the obstacle avoidance or material sorting action.

[0045] It is worth noting that during the entire force transmission and flipping process, the first inclined plane 142a will preferentially contact the interfering external force. Through the guiding and buffering effect of the inclined plane, the external force is gradually decomposed and slowly transmitted to the compression spring 147. This not only effectively buffers the instantaneous impact force and avoids damage to the parts due to rigid collision, but also guides the pallet 12 to complete the flipping action smoothly and gradually, ensuring the stability and continuity of the sorting process.

[0046] The tilting sorting unit 1 also includes a protective component specifically designed to ensure the safety of equipment operation and the stability of pallet 12 during tilting. This protective component consists of three core parts: a protective plate 161, a protective plate bracket 162, and shock absorbers 163. The protective plate 161 has a hollow structure and is made of transparent PC material. Its inner side is securely fixed to the upper side of the upright plate 13 via a matching protective plate bracket 162. Two shock absorbers 163 are fixedly mounted on the inner wall of the protective plate bracket 162, and their installation positions are strictly symmetrical about the vertical axis of the hinge between the pallet 12 and the upright plate 13. Through the limiting effect of the shock absorbers 163, the pallet 12 can be stably confined within the tilting working position range preset by the shock absorbers 163 on both sides, avoiding excessive offset or shaking during the tilting process of the pallet 12, and ensuring the accuracy and stability of the sorting operation.

[0047] This invention also provides a circular tilting tray sorting device, see reference. Figure 5 The ring-shaped tilting sorting equipment includes the aforementioned tilting sorting unit 1 as its core component, supplemented by other triggering components, to achieve material sorting. Based on this, the ring-shaped tilting sorting equipment also includes a bearing guide rail 2, a tilting sorting unit 1, a motor assembly 3, a package unloader 4, and a mechanical reset unit 5.

[0048] The support guide rail 2 is circular. Multiple tilting sorting units 1 are connected end-to-end on the upper side of the support guide rail 2 via a first connector 113 and a second connector 114. The traveling wheels 115 are in contact with the top plane of the support guide rail 2, while the limiting wheels 116 are in contact with the inner surface of the support guide rail 2. Motor assemblies 3 are spaced along the support guide rail 2 and located below it. The spacing can be flexibly adjusted according to requirements. The motor assemblies 3 are used to drive the push plate 15 and the tilting sorting units 1 forward. (See reference...) Figure 6 The motor assembly 3 adopts a contactless linear motor, which has a central channel extending along the axis inside. Guide wheels are provided on both sides of the inlet and outlet of the central channel. Under the action of electromagnetic thrust and guide wheels, the thrust plate 15 moves in a straight line along the central channel.

[0049] The guide rail 2 is equipped with a lower unloader 4 and a mechanical reset unit 5 on both sides. The lower unloader 4 is used to provide external force to cause the pallet 12 to flip, and the mechanical reset unit 5 is used to provide external force to cause the pallet 12 to reset.

[0050] See Figures 7 to 9 The unloader 4 includes a mounting bracket 41, a top rod 42, and a driver 43. The mounting bracket 41 is fixed to the side of the bearing guide rail 2. The top rod 42 is connected to the mounting bracket 41 via a bearing, with a top roller 44 at one end and the other end connected to the power output end of the driver 43. The driver 43 is mounted on the mounting bracket 41 and can be a motor, electromagnet, or cylinder. Its power output end is connected to the top rod 42 via a connecting rod 45. The connection between the connecting rod 45 and the top rod 42 is close to the bearing, which is located between the top roller 43 and the connecting rod 45. Therefore, the driver 43 can drive the top rod 42 to swing. The driver 43 is also equipped with a shock absorber 46 to improve stability. Driven by the driver 43, the top rod 42 can be raised or hidden: when the top rod 42 is raised, its top roller 44 can lift the pressure plate 142 of the moving tilting sorting unit 1 to complete the tilting sorting action; when the top rod 42 is hidden, its top roller 44 is hidden under the pressure plate 142 and will not change the working state of the tilting sorting unit 1.

[0051] To prevent the sorting unit 1 from jamming due to foreign objects entering it while the sorting equipment is in operation, thus preventing it from completing the flipping action, and the system still determining that the sorting unit 1 needs to execute the flipping command according to the preset program, thereby causing hard mechanical wear to the jammed sorting unit 1 during the execution of the unloading action by the unloader 4, this invention adds an active protection mechanism to the unloader 4. This active protection mechanism is embodied in a specially designed triangular notch 47 in the middle of the top rod 42 of the unloader 4. The opening direction of the triangular notch 47 is towards the front end of the flipping sorting unit 1 as it travels along the guide rail. When the above-mentioned abnormal situation occurs where the sorting unit 1 jams and the system issues a flipping command, the top rod 42 of the unloader 4 will trigger the structure at the triangular notch 47 to break due to the jamming resistance of the sorting unit 1. The drive force transmission to the sorting unit 1 is actively cut off by the self-break of the top rod 42, thereby effectively protecting the jammed flipping sorting unit 1 and avoiding further mechanical damage to it. From the perspective of maintenance cost and efficiency, the maintenance cost and required labor time of a single unloading device 4 are far lower than the maintenance cost and downtime of a sorting unit 1, which can significantly reduce the overall maintenance loss of the equipment.

[0052] See Figure 10 The mechanical reset unit 5 is a guide tube fixed on both sides of the bearing guide rail 2. The guide tube is arranged from low to high and then flat along the traveling direction of the flip-type sorting unit 1. With the arc design of the bottom of the positioning card plate 144, the flipped pallet 12 is gradually lifted from the bottom of the pallet 12 to the horizontal working position.

[0053] This invention provides a practical application embodiment of a circular tilting sorting device, which is divided into a package feeding area, a coding identification area, a sorting area, and a reset area along the circular structure of the bearing guide rail 2. See the schematic diagram for the partitioning diagram. Figure 5 In the package feeding area, packages are manually placed onto pallets 12. The coding and identification area is equipped with an intelligent coding reader 7, which is used to identify the barcodes on the packages and assign them to sorting slots 6. The sorting area is equipped with multiple unloading devices 4 and multiple sorting slots 6. Packages are dropped into the corresponding sorting slots 6 according to the information provided by the logistics system for flipping pallets 12. The reset area is equipped with a mechanical reset unit 5. Any pallet 12 passes through the package feeding area, coding and identification area, sorting area and reset area in sequence, and then returns to the package feeding area to enter the next sorting cycle.

[0054] After the logistics system obtains the barcode information on the surface of the package through the intelligent code reader 7, it quickly determines the target sorting slot 6 corresponding to the package by combining the system's preset sorting rules with the database. Subsequently, the system relies on the position signals collected in real time by the positioning sensors configured on the tilting sorting unit 1 to capture the real-time movement trajectory and location of the sorting unit 1, and realizes the coordination between the system and the equipment through signal interaction. When the system confirms that the pallet 12 carrying the package has accurately arrived at the preset workstation near the target sorting slot 6 and has completed its positioning, it will immediately send an action command to the corresponding unloading device 4 to drive the top rod 42 to work, which will drive the tilting sorting unit 1 to complete the tilting action, thereby realizing the sorting of the package.

[0055] Based on the operating mechanism of the tilting sorting unit 1 of the present invention, the carrying guide rail 2 supports multiple layout types. (See also...) Figure 11 The load-bearing guide rail 2 comprises multiple rail segments and columns, with the rails detachably fixed to the columns 23. Each rail segment is either a straight rail 21 or a curved rail 22. The radius of curvature of the curved rail can be selected from 1500mm, 2000mm, or 2500mm to adapt to different site widths, and the turning angle can be selected from 90° / 180°, i.e., a 1 / 4 curved rail or a 1 / 2 curved rail. A polyurethane guide strip can be installed on the inner side of the curved rail to reduce friction when the sorting unit 1 turns. Multiple rail segments are spliced ​​to form a complete load-bearing guide rail, with each segment connected by flanges and bolts.

[0056] Apart from Figure 5 The O-type load-bearing guide rail shown is as follows: Figures 12 to 14 As shown, this invention also provides various modular splicing methods, but the line layout is not limited to the L-shaped, U-shaped, or S-shaped layouts shown in the figure, and can be flexibly combined according to customer needs. Simultaneously, the motor assembly 3 can be arranged according to the actual splicing method of the track to avoid insufficient power. This design breaks through the layout limitations of traditional integrated circular guide rails. However, it should be noted that since the movement of the tilting sorting unit 1 is supported by the push plate 15, the motor assembly 3 must avoid curved tracks when arranging it on the load-bearing guide rail.

[0057] In summary, the circular tilting sorting equipment of the present invention is based on the core design concept of "modular splicing, contactless drive, and automatic reset". The components work together through the following logic: package feeding area → intelligent code recognition device (positioning sorting slots) → motor assembly (driving the tilting sorting unit) → carrying guide rail (conveying path) → unloading device (triggering tilting sorting) → mechanical reset unit (resetting) → package feeding area, forming a closed-loop sorting process. The tilting sorting unit is the core execution component, the carrying guide rail is the path foundation, and the unloading device and mechanical reset unit are the key action triggering components.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
