Description

[0001] This invention application is a divisional application of a logistics sorting assembly line, and the original application document was filed on 2021-08-24, with application number CN202110976802.6 and invention titled "A Logistics Sorting Assembly Line". Technical Field

[0002] This invention relates to the field of logistics sorting technology, specifically to a sorting cart for a logistics sorting assembly line. Background Technology

[0003] With the rapid development of e-commerce, people enjoy the convenience of online shopping and also want to receive their carefully selected items as quickly as possible. This poses a challenge to logistics and delivery. Because the size of warehouses, the number of orders, and the types of goods vary from distribution center to distribution center, sorting methods also differ. However, the commonly used sorting method is generally division of labor, with manual sorting being the earliest form of express delivery sorting, mainly relying on human visual inspection and handling. But with the development of e-commerce, the volume of orders has increased rapidly, the delivery area has expanded, and labor costs have become increasingly high, efficiency has decreased, and demands for error rates, management efficiency, and user experience have changed. Manual sorting alone will inevitably be insufficient to complete the sorting task and may even hinder delivery efficiency and service quality. To respond to market demand, various sorting equipment has emerged and been put into use. However, in the sorting of oversized packages such as large, overweight, and irregularly shaped items that cannot be handled by sorting machines, especially in the less-than-truckload (LTL) logistics industry, manual sorting still plays an important role.

[0004] As order volume increases, manual sorting cannot keep up with demand. Moreover, the high labor requirements and long hours of sorting can lead to fatigue, reduce sorting efficiency, and increase the risk of errors. Furthermore, manual sorting is inconvenient during classification and loading, and can easily cause the accumulation of items. Therefore, we propose a sorting cart for a logistics sorting assembly line. Summary of the Invention

[0031] 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 a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are not applicable.

[0032] All embodiments are within the scope of protection of this invention.

[0033] Please see Figure 1 , Figure 2 and Figure 3 The diagram shows a sorting trolley for a logistics sorting line, comprising a base frame 1, a U-shaped frame 2, an outer rail 3, and an inner rail 7. The U-shaped frames 2 are fixedly connected at equal intervals on both sides of the top of the base frame 1. The outer rail 3 is provided above the base frame 1. The inner walls of the opposite sides of the U-shaped frames 2 are fixedly connected to the outer rail 3. The inner rails 7 are symmetrically arranged inside the outer rail 3. The inner walls of the U-shaped frames 2 away from the outer rail 3 are fixedly connected to the corresponding side of the inner rail 7. A transport mechanism 5 is installed above the base frame 1, and drive mechanisms 8 are installed on both sides of the base frame 1.

[0034] Driven by the drive mechanism 8, the rotating wheel 57 of the transport mechanism 5 transports items via gears, facilitating the sorting process for workers on both sides of the base frame 1 and accelerating sorting speed and efficiency. The storage bin 51 on the transport mechanism 5 can rotate, allowing items to fall into the corresponding storage box 4 during sorting, facilitating centralized classification and storage of sorted items and making logistics sorting more convenient and simple. The drive mechanism 8 allows the motor 86 to drive the connecting plate 56 and the rotating wheel 57 to rotate around the outer rail 3 and inner rail 7 via gears, transporting the storage bin 51. Simultaneously, the support wheel 54 travels along the upper and lower sides of the inner rail 7, and the receiving wheel 512 travels along the inner wall of the outer rail 3. With the support of the inner rail 7 and the guidance of the outer rail 3, the transport is stable, preventing items from shaking and slipping, and providing effective support for transporting and sorting heavier items.

[0035] Please see Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The transport mechanism 5 includes a storage bin 51, a support plate 52, an L-shaped piece 55, a connecting piece 56, a rotating wheel 57, a lower pad 58, a connecting shell 513, a U-shaped rod 514, a connecting plate 515, a rotating rod 516, and a C-shaped shell 519. Connecting pieces 56 are symmetrically arranged at equal intervals between the outer rail 3 and the inner rail 7. L-shaped pieces 55 and lower pads 58 are symmetrically arranged at equal intervals between the outer rail 3 and the inner rail 7. The bottom sides of the L-shaped pieces 55 are rotatably connected to the corresponding connecting pieces 56 via pins. The top sides of the lower pads 58 are rotatably connected to the corresponding connecting pieces 56 via pins. Rotating wheels 57 are symmetrically arranged between adjacent connecting pieces 56 above the base frame 1. The rotating wheels 57 are rotatably connected to the corresponding connecting pieces 56 via pins on both sides. C-shaped shells 519 are symmetrically arranged between the outer rail 3 and the inner rail 7. Each C-shaped shell 519 is fixedly connected to a corresponding L-shaped piece 55. A connecting shell 513 is fixedly connected to one side of the top of each C-shaped shell 519. A connecting plate 515 is symmetrically fixedly connected to the top of each connecting shell 513. A U-shaped rod 514 is fitted onto the top of each connecting plate 515. A storage hopper 51 is provided above each C-shaped shell 519. A support plate 52 is fixedly connected to the bottom of each storage hopper 51. The U-shaped rod 514 is fixedly connected to the bottom of the corresponding support plate 52. A rotating rod 516 is provided at the bottom of the support plate 52. Both ends of the rotating rod 516 pass through the adjacent U-shaped rod 514 and the connecting plate 515 in sequence and are rotatably connected to the inner walls of both sides of the corresponding support plate 52 through bearings. The rotating rod 516 is fixedly connected to the corresponding connecting plate 515 and is rotatably connected to the corresponding U-shaped rod 514 through bearings.

[0036] When the storage hopper 51 is used for sorting, the rotating wheel 57 will rotate along the inner wall of the inner rail 7. According to the sorting requirements, when the items on the storage hopper 51 reach the corresponding storage box 4, the storage hopper 51 will be rotated, so that the U-shaped rod 514 of the support plate 52 will rotate around the rotating rod 516 as the axis, thereby flipping the storage hopper 51 and dropping the items into the corresponding storage box 4, thus sorting the items.

[0037] Please see Figure 4 , Figure 5 and Figure 6 The drive mechanism 8 includes a fixed frame 81, a partition plate 82, a driven shaft 83, a driven gear 84, a driving gear 85, a motor 86, and a driving shaft 87. The driven shaft 83 and the driving shaft 87 are respectively provided on both sides of the base frame 1. The fixed frames 81 are fixedly connected to both sides of the top of the base frame 1. The top ends of the driven shaft 83 and the driving shaft 87 are rotatably connected to the corresponding fixed frames 81 through bearings. The bottom ends of the driven shaft 83 and the driving shaft 87 are rotatably connected to the base frame 1 through bearings. The driving gear 85 is sleeved and fixedly fixed to the outside of the driving shaft 87. The driven gear 84 is sleeved and fixedly fixed to the outside of the driven shaft 83. The driving gear 85 and the driven gear 84 are connected in a transmission connection. The partition plates 82 are symmetrically sleeved and fixed to the outside of the driven shaft 83 and the driving shaft 87. The two ends of the inner rail 7 are respectively fixedly connected to the corresponding partition plates 82. The motor 86 is fixedly installed on one side of the bottom of the base frame 1. The output end of the motor 86 is fixedly connected to the corresponding end of the driving shaft 87.

[0038] During sorting, the motor 86 drives the drive shaft 87 to rotate. The drive gear 85 of the drive shaft 87 drives the C-shaped shell 519 to transport through the rotating wheel 57 between the gear teeth. In this way, multiple storage bins 51 are simultaneously driven to rotate and transport between the outer rail 3 and the inner rail 7 to sort the items on the storage bins 51.

[0039] Please see Figure 1 The base frame 1 is provided with storage boxes 4 at equal intervals on both sides, which makes it convenient to classify and store the sorted items.

[0040] Please see Figure 3 and Figure 7 The outer rail 3 is fixedly connected to a receiving rail 6 on the opposite side, so that the limiting wheel 510 can roll along the receiving rail 6 when the storage hopper 51 is conveying, making the conveying more stable.

[0041] Please see Figure 7 and Figure 8The top and bottom inner walls of the C-shaped shell 519 are fixedly connected to U-shaped shells 53. Each U-shaped shell 53 is equipped with a support wheel 54. The two sides of the support wheel 54 are respectively rotatably connected to the inner walls of the corresponding U-shaped shell 53 by pins, so that the support wheel 54 can move along the top and bottom of the inner rail 7, strengthen the support, and make the goods more stable during transportation.

[0042] Please see Figure 7 and Figure 9 Each of the C-shaped shells 519 has a receiving shell 511 fixedly connected to one side near the outer rail 3. Each receiving shell 511 has a receiving wheel 512 inside. Both sides of the receiving wheel 512 are rotatably connected to the inner walls of the corresponding receiving shell 511 by pins. The receiving wheel 512 can travel along the inner wall of the outer rail 3 during transport.

[0043] Please see Figure 7 and Figure 9 Each of the C-shaped shells 519 has a fixed shell 59 symmetrically fixedly connected to one side of the outer rail 3. Each fixed shell 59 is equipped with a limiting wheel 510 inside. The two sides of the limiting wheel 510 are rotatably connected to the inner walls of the corresponding fixed shell 59 through bearings, so that the limiting wheel 510 can roll along the receiving rail 6 when the storage hopper 51 is conveying, making the conveying more stable.

[0044] Please see Figure 9 Each of the C-shaped shells 519 has a fixed block 517 fixedly connected to its top, and each of the fixed blocks 517 has a soft pad 518 fixedly connected to its top to avoid hard contact and provide shock absorption protection.

[0045] Working Principle: During sorting, the motor 86 drives the drive shaft 87 to rotate. The drive gear 85 of the drive shaft 87 drives the C-shaped housing 519 for conveying through the rotating wheel 57 between the gear teeth. In this way, multiple storage hoppers 51 are simultaneously conveyed around the outer rail 3 and the inner rail 7 to sort the items on the storage hoppers 51. When the storage hoppers 51 are conveying and sorting, the rotating wheel 57 rotates along the inner wall of the inner rail 7. According to the sorting requirements, when the items on the storage hoppers 51 reach the corresponding storage boxes 4, the storage hoppers 51 are rotated, causing the U-shaped rod 514 of the support plate 52 to rotate around the rotating rod 516 as the axis, thereby flipping the storage hoppers 51 and dropping the items into the corresponding storage boxes 4, thus sorting the items. The rotating wheel 57 of the transport mechanism 5, driven by the drive mechanism 8, moves the items through the gears. The conveyor system facilitates streamlined sorting operations for workers on both sides of the base frame 1, accelerating sorting speed and efficiency. Furthermore, the storage bin 51 on the conveyor mechanism 5 can rotate, allowing items to fall into the corresponding storage box 4 during sorting. This facilitates centralized classification and storage of sorted items, making logistics more convenient and simpler. The drive mechanism 8 allows the motor 86 to drive the connecting plate 56 and the rotating wheel 57 to rotate around the outer rail 3 and inner rail 7 via gears, conveying the storage bin 51. Simultaneously, the support wheel 54 travels along the upper and lower sides of the inner rail 7, while the receiving wheel 512 travels along the inner wall of the outer rail 3. With the support of the inner rail 7 and the guidance of the outer rail 3, the conveying process is stable, preventing items from swaying and slipping, while also providing effective support, facilitating the transport and sorting of heavier items.
