Description

Technical Field

[0001] The present application relates to the technical field of technical equipment, and in particular to a multi-layer material storage automatic sorting line. Background Art

[0002] Material sorting is the process of classifying, centralizing and arranging items according to order requirements. Sorters classify items according to type, specification, quantity, etc. based on order information, and then place them in designated cargo spaces or shipping areas for subsequent distribution or storage. Material sorting is an important part of material operations, which can improve material efficiency and accuracy, reduce errors and losses. With the development of automation and intelligent technology, many logistics companies have begun to adopt automated sorting equipment and technologies, such as automatic sorting systems, robot sorting, etc., to improve sorting efficiency and accuracy and reduce labor costs.

[0003] In the prior art, material sorting lines that use automation technology perform sorting mechanically, thereby achieving fast and efficient automatic sorting of materials. Setting up multi-layer sorting lines can not only improve space utilization, but also accommodate more packages, thereby improving sorting efficiency.

[0004] However, considering the huge size of the equipment and the large number of them, although the multi-layer design can make full use of the vertical space, in some cases, due to the limitations of cargo size and weight, the sorting lines at different levels may not be fully utilized, resulting in low space utilization. Therefore, a logistics warehousing sorting line that can be stacked in multiple layers is needed. Summary of the invention

[0005] In view of the shortcomings of the existing technology, the purpose of this application is to provide a multi-layer material storage automatic sorting line to solve the problem of insufficient equipment space utilization.

[0006] The above-mentioned purpose of the present application is achieved through the following technical solutions: a multi-layer material storage automatic sorting line, including a material storage structure, a material transportation structure and a material sorting and collecting structure, the material sorting and collecting structure includes a chassis and a plurality of sorting boxes, the chassis is provided with a sorting conveyor belt for sorting and transporting goods, the sorting conveyor belt is divided into an upper sorting line and a lower sorting line, a connecting frame is provided in the middle of the upper sorting line and the lower sorting line for fixed connection, and the sorting boxes are evenly distributed on both sides of the sorting conveyor belt.

[0007] By adopting the above technical solution, the chassis in the multi-layer sorting structure is provided with a connecting frame, so that the upper and lower sorting lines are fixed together to form an upper and lower stack. While the upper sorting line is sorting large shelves, the lower sorting line is also sorting small items at the same time, which improves space utilization and sorting efficiency.

[0008] Furthermore, the material storage structure includes a storage room and a lifting platform, the material transportation structure includes a diverter conveyor belt, the diverter conveyor belt includes a first conveyor belt and a second conveyor belt, a diverter rack is arranged in the middle of the second conveyor belt, the first conveyor belt is placed under the diverter rack, the first conveyor belt is connected to the lower sorting line, and the second conveyor belt is connected to the upper sorting line.

[0009] By adopting the above technical solution, when the goods are transferred from the lifting platform to the diversion conveyor belt, as the conveyor belt starts, the goods are conveyed to the diversion rack by the second conveyor belt, and the small goods will enter the first conveyor belt from under the diversion rack, and then be transferred to the lower sorting layer with the first conveyor belt for sorting, while the large goods will continue to be transferred to the upper sorting line on the second conveyor belt for sorting.

[0010] Furthermore, a conveyor belt motor is arranged on the second conveyor belt driving shaft and is fixedly connected to the second conveyor belt, and a synchronous belt is arranged on the second conveyor belt driving shaft and the first conveyor belt driving shaft sleeve.

[0011] By adopting the above technical solution, the conveyor belt motor drives the second conveyor belt, and at the same time the synchronous belt drives the first conveyor belt together to transport the goods.

[0012] Furthermore, two diverter rods are arranged on the diverter rack, and the diverter rods are in an eight-shaped shape, with the narrow end being arranged close to the conveyor belt motor.

[0013] By adopting the above technical solution, when the goods in the warehouse are transmitted along the second conveyor belt, the small goods will continue to fall into the first conveyor belt as the distance between the diverter rods increases, while the large goods will continue to be transmitted forward along the conveyor belt, thereby achieving the purpose of diversion.

[0014] Furthermore, one end of the two diverter rods away from the second conveyor belt driving shaft is slidably connected to the diverter rack and an elastic rope is arranged between the two diverter rods. The other end of the diverter rod is rotationally connected to the diverter rack, and both ends of the elastic rope are respectively fixedly connected to the two diverter rods.

[0015] By adopting the above solution, when encountering cargo of moderate size, the cargo may get stuck in the middle of the diverter rod. The setting of the elastic rope will increase the distance between the diverter rods as the cargo is squeezed, causing the cargo to fall into the first conveyor belt and the material transportation structure to get stuck.

[0016] Furthermore, the sorting conveyor belt is ring-shaped.

[0017] By adopting the above technical solution, when there are more and more parcels, if some parcels do not enter the sorting box along the sorting line, they can be transmitted again on the sorting conveyor belt for one circle to complete the sorting work again, thereby reducing errors during sorting.

[0018] Furthermore, baffles are provided on both sides of the upper sorting line.

[0019] By adopting the above technical solution, as the upper sorting line runs, there will be more and more parcels, and there may be a problem that the parcels will be separated from the upper sorting line. The setting of the baffle will block the parcels on the upper sorting line to prevent them from entering the lower sorting line and causing the parcels to go wrong.

[0020] Furthermore, the baffle and the sorting conveyor belt are plugged into each other.

[0021] By adopting the above technical solution, when the sorting line stops sorting, it is convenient to overhaul and maintain the equipment.

[0022] Furthermore, the sorting boxes distributed on the upper sorting line and the lower sorting line are staggered.

[0023] By adopting the above technical solution, after the sorting work is completed, the sorting boxes on the upper sorting line are dropped. Considering that the goods on the upper layer are all large goods, the small goods in the sorting boxes of the lower sorting line will not be crushed.

[0024] Furthermore, the sorting conveyor belt is provided with anti-sliding blocks, and the anti-sliding blocks are evenly distributed on the sorting conveyor belt.

[0025] By adopting the above technical solution, since the sorting conveyor belt is ring-shaped, when the sorting conveyor belt conveys the goods to the ring-shaped position, it may be displaced due to inertia. The setting of the anti-sliding block will prevent the displacement of the goods passing through the ring-shaped position, thereby ensuring that the possibility of displacement of the goods is greatly reduced during the entire sorting process.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The upper sorting line and the lower sorting line are superimposed together through multiple connecting frames. The upper and lower sorting lines are used to sort different types of goods, which improves the original space utilization and improves the sorting efficiency.

[0028] 2. The setting of the diverter rack. When different goods are placed on the second conveyor belt from the storage room, as the conveyor belt is transported to the diverter rack, the small goods will enter the first conveyor belt from under the diverter rod and then reach the lower sorting line, while the large goods will continue to move forward with the conveyor belt and reach the upper sorting line for sorting, thus realizing the diversion of goods. The setting of the diverter rod. When the goods are transported to the diverter rack with the second conveyor belt, after the goods are stuck, the elastic rope will be gradually lengthened by gravity, so that the goods will fall onto the first conveyor belt, thereby ensuring diversion during logistics transportation and ensuring the normal operation of the structure.

[0029] 3. Baffles are set at both ends of the upper sorting line. As the sorting work is carried out, the number of parcels will increase. The baffles will block the parcels in the upper sorting line to prevent the parcels in the upper sorting line from being thrown into the lower sorting line as the sorting conveyor belt rotates, which will cause sorting errors.

[0030] 4. Anti-slip blocks are evenly arranged on the sorting conveyor belt. When the goods enter the upper sorting line along the second conveyor belt, since the sorting conveyor belt is annular, as the sorting conveyor belt rotates, when the goods reach the arc position, the goods may be displaced due to inertia, which will cause sorting errors. When the anti-slip block is set, the displacement of the goods on the sorting conveyor belt will be reduced, thereby reducing sorting errors. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The present application is further described in detail below in conjunction with the accompanying drawings.

[0038] Example, see Figure 1 , Figure 2 , Figure 3 , a multi-layer material storage automatic sorting line includes a material storage structure, a material transportation structure, and a material sorting and collecting structure. The material sorting structure includes a sorting conveyor belt 502 and a plurality of sorting boxes 4. The sorting conveyor belt 502 is divided into an upper sorting line and a lower sorting line. A connecting frame 5 is provided between the upper sorting line and the lower sorting line and the two sorting lines are fixedly connected together to form an upper and lower stack. The logistics transportation structure includes a first conveyor belt 201 and a second conveyor belt 202. A conveyor belt motor 2 is provided on the driving shaft of the second conveyor belt 202 and is fixedly connected to the second conveyor belt 202. A synchronous belt 3 is provided on the driving shaft of the second conveyor belt 202 and the first conveyor belt 201. The second conveyor belt 202 is connected to the upper sorting line in the direction of the delivery end, and the first conveyor belt 201 is connected to the lower sorting line in the direction of the delivery end. A diverter rack 301 is arranged between the conveyor belt 202 and the upper sorting line, and the other end of the first conveyor belt 201 is provided below the diverter rack 301. The material storage structure includes a storage room 1 and a lifting platform 102. When sorting goods, the goods in the storage room 1 are moved to the second conveyor belt 202 along the lifting platform 101, and the conveyor belt motor 2 drives the second conveyor belt 202. Different goods are conveyed to the end of the second conveyor belt 202 and arrive at the diverter rack 301. Small goods will enter the first conveyor belt 201 and enter the lower sorting line, while large goods will enter the upper sorting line for sorting. An automatic sorting device is laid on the sorting line. The upper and lower sorting lines respectively sort different types of goods, which will improve the space utilization rate of the sorting line while ensuring the sorting efficiency.

[0039] In order to sort the goods of different sizes separately, in this example, a diverter rack 301 is set at the end of the second conveyor belt, and two diverter rods 302 are set in the middle of the diverter rack 301. The diverter rods 302 are gradually opened from the second conveyor belt to the upper sorting layer. When the large goods are conveyed to the position of the diverter rack 301 by the second conveyor belt, they will be directly conveyed to the upper sorting line, while when the small goods are conveyed to the diverter rack 301 by the second conveyor belt, they will enter the lower sorting line as they are conveyed, thereby achieving the purpose of diverting the goods according to size.

[0040] In order to prevent a portion of the cargo from getting stuck on the diversion rack 301 when encountering a cargo that is neither too big nor too small, in this embodiment, Figure 4One end of the diverter rod 302 away from the driving shaft of the second conveyor belt 202 is a sliding connection diverter rack 301, and is connected by an elastic rope 303, and the other end is a sliding connection. When the goods are stuck between the two diverter rods 302, the elastic rope 303 will be stretched due to gravity, so that the stuck goods will fall onto the first conveyor belt 201, thereby achieving the purpose of preventing the goods from getting stuck in the diverter rack 301.

[0041] In order to prevent the goods from the upper sorting line from falling into the lower sorting line during the sorting process, in this embodiment, Figure 1 Baffles 401 are provided at both ends of the upper sorting line. As the sorting line performs sorting, the number of large items on the upper layer will increase. When the items are transmitted along the sorting conveyor belt 502 and accidentally reach the edge of the sorting line, the baffles 401 will block the items, thereby ensuring that they will not fall from the upper sorting line to the lower sorting line.

[0042] Since the sorting conveyor belt 502 is annular, in order to prevent the goods from being displaced due to inertia when reaching the arc position, thereby causing errors during sorting, in this embodiment, reference is made to Figure 1 , Figure 5 , anti-sliding blocks 503 are provided on the sorting conveyor belt 502 and are evenly distributed on the sorting conveyor belt 502. When the goods rotate along with the sorting conveyor belt 502 and reach the arc position, the anti-sliding blocks 503 will increase the friction between the goods and the bottom, so as to reduce the displacement of the goods.

[0043] In a specific implementation manner, the sorting conveyor belt 502 is stacked up and down to build a second layer of space in the original one layer, which increases the number of equipment and improves the utilization rate of space, and also improves efficiency. A lifting platform 102 is arranged on one side of the storage room 1. After the lifting platform 102 brings the goods to the second conveyor belt 202, as the conveyor belt motor is started, the rotating shaft of the second conveyor belt 202 and the driving shaft of the first conveyor belt 201 are connected through the synchronous belt 3. The conveyor belt motor 22 drives the second conveyor belt 202 and also drives the first conveyor belt 201. The middle of the second conveyor belt 202 A diverter rack 301 is provided. When the goods arrive at the diverter rack 301, the diverter rod 302 on the diverter rack 301 gradually expands from the output end of the second conveyor belt 202 to the other end. After the small goods are conveyed to the diverter rack 301, they will fall into the first conveyor belt 201, and then enter the second conveyor belt 202 along the first conveyor belt 201, while the large goods will enter the upper sorting line along the diverter rack 301, thereby realizing the diversion of goods of different sizes. The upper and lower sorting lines sort two different sizes of goods, thereby improving space utilization and improving sorting efficiency.

[0044] Since the sizes of the goods are different, the size of the goods may just be stuck on the diverter rod 302 on the diverter rack 301. Therefore, the end of the diverter rod 302 away from the driving axis of the second conveyor belt 202 is a sliding connection, and the other end is a rotating connection. An elastic rope 303 is set at one end of the sliding connection to connect the diverter rod 302 together. When the goods are conveyed to the diverter rack 301 along the second conveyor belt 202, after the goods are stuck, the elastic rope 303 will be gradually stretched by gravity, so that the goods will fall onto the first conveyor belt 201, thereby ensuring the normal operation of the logistics transportation structure.

[0045] The anti-slip blocks 503 are evenly arranged on the sorting conveyor belt 502. Since the sorting conveyor belt 502 is annular, when the goods rotate to the arc position with the sorting conveyor belt 502, they may be displaced due to inertia, thereby causing sorting errors. The anti-slip blocks 503 are arranged so that when the goods reach the arc position with the rotation of the sorting conveyor belt 502, the friction between the goods and the bottom is increased, thereby reducing the possibility of displacement.

[0046] Since the sorting conveyor belt is annular, anti-slip blocks 503 are provided on the sorting conveyor belt 502 and are evenly distributed on the sorting conveyor belt 502. When the goods rotate with the sorting conveyor belt 502 and reach the arc position, the anti-slip blocks 503 will increase the friction between the goods and the bottom, thereby reducing the displacement of the goods.

[0047] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
