Description
Technical Field
[0001] This utility model relates to the technical field of cargo sorting, specifically to a flat-push 3D circular sorting device. Background Technology
[0002] Automated cargo sorting systems are a highly efficient solution in the field of modern logistics warehousing. Compared with the traditional planar sorting mode, they have a series of significant advantages: they make full use of the vertical space of the warehouse through multi-layer racking structure and dense storage strategy; they have ultra-high processing efficiency and sorting speed, and multi-layer sorting workstations and multiple elevators can work at the same time to achieve true parallel processing.
[0003] Chinese patent application CN202411088067.5, entitled "Three-dimensional sorting loop system and method," discloses a three-dimensional sorting loop system and method. The lifting unit is equipped with a pulley assembly that slides in contact with a circular track. Adjacent lifting units are connected by a linkage assembly, forming a loop. Although the lifting unit can drive adjacent lifting units to slide on the circular track via the linkage assembly, the connecting assembly cannot be bent. Therefore, when passing through a curved track, the length of the broken line shape formed by the linkage assembly and pulley assembly deviates significantly from the actual length of the curved track. This results in poor stability and smooth sliding when the lifting unit slides through the curved track, and is prone to producing abnormal noise. Therefore, a flat-push 3D loop sorting device needs to be designed. Utility Model Content

[0006] Each annular track is slidably connected with an annular chain. The annular connection includes several chain links that are hinged in sequence. At the hinge point of two adjacent chain links, a first pulley is fitted to slide in contact with the outer wall of the annular track. Multiple chain links are arranged between two adjacent sets of lifting units. The lifting unit includes a first mounting frame whose upper and lower ends are fixedly connected to the corresponding chain links. An annular magnetic drive unit is mounted on the frame. The lower end of the first mounting frame is fitted with a fifth pulley that slides in contact with the upper surface of the annular track below.

[0010] The pulley assembly includes several third pulleys spaced vertically and slidingly contacting the two side walls opposite to the chute, and at least one fourth pulley slidingly contacting the middle side wall of the chute.
[0011] Preferably, the horizontal conveying mechanism includes a second mounting frame fixedly connected to the lifting frame, a horizontal electric roller mounted on the second mounting frame, a driven roller arranged parallel to the electric roller on the second mounting frame, and a conveyor belt sleeved on the outside of the electric roller and the driven roller.
[0012] Preferably, the annular magnetic drive unit includes several secondary plates that are one-to-one mounted on several lifting units and a linear motor mounted on the frame and matched with the several secondary plates.

[0015] Preferably, the outer surface of the conveyor belt is provided with at least one limiting strip, and the second mounting frame includes baffles located on both sides of the conveyor belt.
[0016] According to the above technical solution, the beneficial effects of the 3D circular sorting equipment provided by this utility model in use are as follows:
[0017] Firstly, the ring chain is slidably connected to the ring track. The ring chain is flexible, which allows each first pulley to fit against the outer wall of the ring track.

[0030] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0031] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.
[0032] like Figure 1-7 As shown, a 3D circular sorting equipment includes: a frame 1, a pair of circular tracks 2 arranged vertically on the frame 1, and several sets of lifting units 3 arranged around the circular tracks 2 at intervals. Each set of lifting units 3 is equipped with a horizontal conveying mechanism 4 on its moving end.
[0033] Each annular track 2 is slidably connected with an annular chain. The annular connection includes several chain links 5 that are hinged in sequence. At the hinge point of two adjacent chain links 5, a first pulley 6 is fitted to slide in contact with the outer wall of the annular track 2. Multiple chain links 5 are arranged between two adjacent sets of lifting units 3. The lifting unit 3 includes a first mounting frame 7 whose upper and lower ends are fixedly connected to the corresponding chain links 5. An annular magnetic drive unit is mounted on the frame 1. The lower end of the first mounting frame 7 is fitted with a fifth pulley 8 that slides in contact with the upper surface of the annular track 2 located below.
[0034] In the above technical solution, the circular track 2 is divided into a pair of straight tracks and a curved track for connecting the pair of straight tracks;
[0035] The ring magnetic drive unit will drive several sets of lifting units 3 to slide around the ring track 2. When the lifting unit 3 slides to the curved track, the goods will be transported to the horizontal conveying mechanism 4, and the lifting unit 3 will continue to slide. When the lifting unit 3 slides to the straight track, the moving end of the lifting unit 3 will drive the horizontal conveying mechanism 4 to move up and down to adjust the height. Then the horizontal conveying mechanism 4 will start to send the goods into the corresponding cargo frame.
[0036] The ring chain is slidably connected to the ring track 2. The ring chain is flexible and can make each first pulley 6 fit against the outer wall of the ring track 2, so as to pass smoothly through the curved track. The ring chain has good smoothness and stability when sliding.
[0037] The ring magnetic drive unit can increase the speed of several sets of lifting units 3 when they make ring movements, thereby improving the efficiency of goods sorting.
[0038] In a preferred embodiment of the present invention, the first mounting bracket 7 is equipped with a second pulley 9 that slides in contact with the inner sidewall of the annular track 2.
[0039] In the above technical solution, the second pulley 9 contacts the inner wall of the ring track 2, which can further improve the stability of the lifting unit 3 when sliding. The second pulley 9 and the corresponding two first pulleys 6 clamp the ring track 2, improving the stability and smoothness of the lifting unit 3 when sliding.
[0040] In a preferred embodiment of the present invention, the lifting unit 3 further includes a lifting frame 10 that is vertically slidably connected to the first mounting frame 7 via a pulley block, a first motor 11 mounted on the upper or lower end of the first mounting frame 7, a pair of synchronous pulleys 12 respectively mounted on the output shaft of the first motor 11 and the end of the first mounting frame 7 away from the first motor 11, and a synchronous belt 13 sleeved on the pair of synchronous pulleys 12, wherein the lifting frame 10 and the synchronous belt 13 are fixedly connected at corresponding positions.
[0041] In the above technical solution, the first motor 11 drives the corresponding synchronous pulley 12 to rotate, thereby driving the lifting frame 10 to move vertically through the synchronous belt 13. The moving speed of the lifting frame 10 is faster than that of the traditional screw slide table.
[0042] The lifting frame 10 is slidably connected to the first mounting frame 7 via a pulley block, which not only reduces the initial equipment cost but also the replacement cost when maintaining and replacing the pulley block later.
[0043] In a preferred embodiment of the present invention, the number of pulley sets is one pair, and the pair of pulley sets are respectively located on both sides of the first mounting frame 7. Vertical grooves 14 are provided on the opposite sides of the first mounting frame 7.
[0044] The pulley assembly includes several third pulleys 15 that are spaced vertically and slide in contact with the side walls opposite to the slide groove 14, and at least one fourth pulley 16 that slides in contact with the middle side wall of the slide groove 14.
[0045] In the above technical solution, the third pulley 15 and the fourth pulley 16 can contact the three side walls of the slide 14, which can restrict the horizontal movement of the lifting frame 10, making the lifting frame 10 slide more smoothly, and the cost of replacing the pulley group later is low.
[0046] In a preferred embodiment of this utility model, the horizontal conveying mechanism 4 is fixedly connected to the second mounting frame 17, the horizontal electric roller 18 is mounted on the second mounting frame 17, the driven roller 19 is arranged parallel to the electric roller 18 on the second mounting frame 17, and the conveyor belt 20 is sleeved on the outside of the electric roller 18 and the driven roller 19.
[0047] In the above technical solution, when picking up goods, the electric roller 18 rotates, causing the upper surface of the conveyor belt 20 to move closer to the lifting frame 10; when unloading, the electric roller 18 rotates in the opposite direction, causing the upper surface of the conveyor belt 20 to move away from the lifting frame 10.
[0048] In a preferred embodiment of the present invention, the annular magnetic drive unit includes a plurality of secondary plates 21 that are one-to-one mounted on a plurality of lifting units 3 and a linear motor 22 mounted on the frame 1 and matched with the plurality of secondary plates 21.
[0049] In the above technical solution, the linear motor 22 driving the secondary plate 21 to move is the existing technology, and its working principle will not be described in this article. The linear motor 22 can drive the corresponding secondary plate 21 to slide along the linear slide rail, thereby driving the ring chain to slide on the ring track 2, driving several sets of lifting units to move simultaneously.
[0050] In a preferred embodiment of this utility model, the annular track 2 is equipped with a shell covering the annular chain.
[0051] In a preferred embodiment of the present invention, the chain link 5 includes strip-shaped connecting pieces arranged vertically. Two adjacent chain links 5 are connected by a hinge bolt and a mounting nut. The hinge bolt passes through the end of the strip-shaped connecting piece. Two strip-shaped connecting pieces in a set of chain links 5 are located outside two strip-shaped connecting pieces in adjacent chain links 5. The first pulley 6 is sleeved on the hinge bolt and located in the middle of a pair of strip-shaped connecting pieces in the chain link 5.
[0052] In a preferred embodiment of the present invention, at least one limiting protrusion 23 is provided on the outer surface of the conveyor belt 20, and the second mounting frame 17 includes baffles located on both sides of the conveyor belt 20.
[0053] In the above technical solution, after the goods are picked up, a pair of limiting protrusions 23 and two baffles can prevent the goods from falling; and the limiting protrusions 23 are conducive to pushing the goods to move, and can provide assistance when picking up and unloading goods.
[0054] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0055] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0056] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
