Description

Technical Field

[0001] The utility model relates to the technical field of logistics automatic sorting equipment, in particular to an express sorting system. Background Art

[0002] A sorting machine is a new type of logistics sorting equipment that can realize automatic and rapid sorting of goods, and is widely used in industries such as express delivery, e-commerce, and clothing.

[0003] Based on the sorting machine, currently, a multi-level sorting mechanism is generally used to distribute goods from the sorting center to the hands of salespersons. Specifically, the multi-level sorting mechanism is carried out in the following manner: the sorting center is responsible for initially classifying and processing items according to regions or routes, and packing or loading them onto corresponding transportation tools to be transported to the regional sorting center; the regional sorting centers are usually located in larger cities or logistics hubs, and they receive the goods from the sorting center and sort and classify them again according to different areas to better meet the delivery needs of the target areas; the distribution centers are usually located within each area, receive the goods from the regional sorting centers, and are responsible for delivering the items to the corresponding salespersons or deliverymen according to their respective scope of responsibilities.

[0004] Reducing the number of levels in the original sorting mechanism can further reduce the sorting cost and improve the sorting efficiency. The reduction of the number of levels in the sorting mechanism will cause the number of sorting categories at each level to increase geometrically, that is, the number of sorting compartments will increase geometrically. Currently, cross-belt sorting machines are generally used in sorting centers for sorting goods. With the increase in the volume of goods sorted and the increase in the number of sorting categories of goods, a larger cross-belt sorting machine is inevitably required. A larger cross-belt sorting machine will lead to an increased risk of failure, a sharp increase in equipment maintenance costs, an increase in the floor area of the sorting workshop, and due to the increase in the number of sorting compartments, the sorting speed of the cross-belt sorting machine will slow down, reducing the sorting efficiency. Moreover, once the cross-belt sorting machine fails, the entire sorting work in the sorting center will stop.

[0005] Therefore, there is an urgent need for an improved express sorting system that can sort more categories of goods, has high sorting efficiency, and occupies a small area. Summary of the Utility Model

[0038] It should be noted that the orientation nouns such as "up", "down", "front", "back", "left", and "right" mentioned in this article are based on Figure 1is used as a reference. A "compartment" is a compartment for storing and sorting items and is the endmost part of the sorting system for sorting.

[0039] Embodiment 1

[0040] As Figure 1 and Figure 2 shown, this embodiment provides an express sorting system, which includes a primary sorting device, a conveying channel 2, and a plurality of linear secondary sorting devices; each secondary sorting device extends in the left - right direction, and the plurality of secondary sorting devices are arranged in sequence in the front - back direction. Each secondary sorting device has at least one secondary sorting layer, and a plurality of sorting outlets with unique corresponding secondary sorting layers are provided on the primary sorting device; the express sorting system can switch between a first mode and a second mode. When the express sorting system is in the first mode, the sorting outlet is connected to its corresponding secondary sorting layer through the conveying channel 2. When the express sorting system is in the second mode, adjacent secondary sorting layers in the horizontal direction are connected through the conveying channel 2 to form a serpentine conveying path.

[0041] The express sorting system arranged as above can, according to sorting requirements, select the first mode or the second mode to sort the goods by changing the connection object of the conveying channel 2, making the sorting work more flexible and reducing the operating cost.

[0042] Specifically, when the express sorting system is in the first mode, the sorting outlet is connected to its corresponding secondary sorting layer through the conveying channel 2. As Figure 1 shown, first, the primary sorting device roughly sorts the goods and conveys them to the secondary sorting device, and then the secondary sorting device finely sorts the goods. The parallel - arranged secondary sorting devices have a small floor area and a large number of sorting compartments, meeting the current demand for an increasing number of sorting categories of goods. At the same time, the sorting categories of the primary sorting device can be reduced, and medium - sized or small - sized primary sorting devices can be selected, reducing the floor area of the workshop and the cost. Moreover, the risk of failure of the primary sorting device is reduced. When the primary sorting device fails, the secondary sorting device can still operate normally for sorting. And because the sorting categories of the primary sorting device are reduced, the sorting speed of the primary sorting device can be faster, thus improving the sorting efficiency. Therefore, the express sorting system in the first mode is suitable for situations with obvious high sorting peaks, especially suitable for the inbound link in logistics sorting.

[0043] When the express sorting system is in the second mode, adjacent secondary sorting layers in the horizontal direction are connected through the conveying channel 2 to form a serpentine conveying path. As Figure 2As shown, the number of sorting bays is large, meeting the current demand for an increasing number of parcel sorting categories. Only by turning on the secondary sorting device, the operating cost is low. However, compared with the first mode, the sorting speed is reduced and the parcel sorting volume is decreased. Therefore, the express sorting system in the second mode is suitable for situations with stable and low sorting peaks, especially suitable for the outbound link in logistics sorting.

[0044] The inbound link refers to parcels coming from other places, which are uniformly sorted at the logistics sorting center and then sent to the next-level network / area for delivery. In this link, a large number of goods will arrive simultaneously, and there are often obvious sorting peaks in the inbound link. The outbound link refers to sending the collected parcels to the next destination or a larger transfer center to send out the parcels. In this link, the sorting peak is relatively low and stable.

[0045] Specifically, in this embodiment, the primary sorting device is the cross-belt sorter 1, and the secondary sorting device is the linear sorter 3. Further, in this embodiment, the cross-belt sorter 1 has a primary sorting layer, and the linear sorter 3 has a secondary sorting layer.

[0046] Among them, the cross-belt sorter 1 is located at one end side of all the linear sorters 3 (i.e., the left or right side of the linear sorter 3), and the cross-belt sorter 1 is provided with a plurality of sorting outlets corresponding to the linear sorters 3 one by one near the straight section of the linear sorter 3.

[0047] It should be noted that when the express sorting system is in the first mode, a certain number of linear sorters 3 can be selected according to the sorting requirements and connected to the sorting outlets through the transfer channel 2; when the express sorting system is in the second mode, a certain number of linear sorters 3 can be selected according to the sorting requirements, and adjacent linear sorters 3 are connected through the transfer channel 2 to form a serpentine conveying path.

[0048] Preferably, in this embodiment, the plurality of linear sorters 3 are arranged in parallel with each other.

[0049] Preferably, as Figure 1 shown, the cross-belt sorter 1 is also provided with bays 11. In the express sorting system provided in this embodiment, the cross-belt sorter 1 performs multi-task sorting on parcels, decomposes the parcels into single tasks and conveys them to the linear sorter 3, and the linear sorter 3 performs single-task sorting; in the actual sorting process, there are often some single tasks with a large sorting volume and some single tasks with a small sorting volume. The single tasks with a large sorting volume can make full use of the working efficiency of the linear sorter 3, and the single tasks with a small sorting volume will cause efficiency redundancy and resource waste of the linear sorter 3. By setting the bays 11 on the cross-belt sorter 1, the single tasks with a small sorting volume can be directly executed, avoiding using the linear sorter 3 to execute the single tasks with a small sorting volume, making the sorting work more flexible and reducing the operating cost.

[0050] Specifically, a feeding table 13 is also provided on the cross belt sorter 1 .

[0051] Preferably, if Figure 1 and Figure 2 As shown, the linear sorting machine 3 has a cargo input port 31, a sorting port and a cargo output port 32. The cargo input port 31 is used to transport cargo to the linear sorting machine 3, the sorting port is used to sort the cargo on the linear sorting machine 3 into the grid port, and the cargo output port 32 is used to transport unsorted cargo outside the linear sorting machine 3; cargo identification devices are provided at the cargo input port 31 and the cargo output port 32 of the linear sorting machine 3. The cargo input port 31 and the cargo output port 32 of the linear sorting machine 3 are generally located at the left and right ends of the linear sorting machine 3. The cargo input port 31 refers to a position near the cargo input port 31, including a position of the conveying channel 2 close to the cargo input port 31, and the cargo output port 32 refers to a position near the cargo output port 32, including a position of the conveying channel 2 close to the cargo output port 32. In this way, the express sorting system is in the first mode, and the transmission channel 2 connects the corresponding sorting outlets and the cargo input ports 31 of the linear sorting machines 3; the express sorting system is in the second mode, and the transmission channel 2 connects the cargo output port 32 of the first linear sorting machine 3 and the cargo input port 31 of the second linear sorting machine 3, and the first linear sorting machine 3 and the second linear sorting machine 3 are arranged adjacent to each other; no matter whether the express sorting system is in the first mode or the second mode, the cargo identification device can identify the cargo input and cargo output of the linear sorting machine 3, which is conducive to ensuring the stable operation of the express sorting system.

[0052] Further preferably, the cargo identification device is a visual camera, a grayscale meter or a multi-surface scanning device. Specifically, in this embodiment, the cargo identification device is a five-surface scanning device or a six-surface scanning device.

[0053] Specifically, Figure 1 and Figure 2 As shown, in this embodiment, the cargo input port 31 of the linear sorting machine 3 is located at a first end portion of the linear sorting machine 3 , and the cargo output port 32 of the linear sorting machine 3 is located at a second end portion of the linear sorting machine 3 .

[0054] Preferably, the conveying channel 2 includes a belt conveyor line and a driving unit, and the driving unit is connected to the belt conveyor line. The conveying channel 2 configured in this way is self-driven, and the goods are transported stably, and can supply packages from the cross belt sorter 1 at a lower position to the linear sorter 3 at a higher position.

[0055] When the cross-belt sorter 1 is at a higher position and the linear sorter 3 is at a lower position, the conveying channel 2 can be a connecting plate without drive, and the goods on the cross-belt sorter 1 can slide freely onto the linear sorter 3 under the action of gravity.

[0056] Preferably, a turning unit and a centering unit for centering the goods on the conveying channel are sequentially arranged on the conveying channel 2 along the conveying direction; when the express sorting system is in the second mode, the turning unit is located at the turning of the conveying channel and is used to change the conveying direction of the goods on the conveying channel. By setting the turning unit, the conveying channel 2 can be used to connect adjacent linear sorting machines 3. Through the centering unit, the situation that the lower package of the cross-belt sorting machine 1 is left-biased or right-biased can be repaired, so that the upper package on the linear sorting machine 3 is centered. Specifically, the turning unit can be a swing-wheel steering mechanism, and the centering unit can be a swing-wheel centering mechanism. The present invention does not limit the specific types of the turning unit and the centering unit. Any mechanical structure capable of realizing the turning function can be used as the turning unit, and any mechanical structure capable of realizing the centering function can be used as the centering unit.

[0057] More preferably, the conveying channel has a first channel portion and a second channel portion connected in sequence along the conveying direction. The centering unit is located at the connection of the first channel portion and the second channel portion, and baffles are arranged on one or both sides of the first channel portion. In this way, it is possible to prevent the goods from falling out of the conveying channel 2.

[0058] Preferably, the conveying channel 2 can be switched between a first shape and a second shape. When the conveying channel 2 is in the first shape, it is used to connect the corresponding sorting outlet and the goods input port 31 of the linear sorting machine 3. When the conveying channel 2 is in the second shape, it is used to connect the goods output port 32 of the first linear sorting machine 3 and the goods input port 31 of the second linear sorting machine 3, and the first linear sorting machine 3 and the second linear sorting machine 3 are arranged adjacent to each other.

[0059] More preferably, the first shape is an inclined line shape, and the second shape is an inverted U shape. In this way, the inclined-line-shaped conveying channel 2 facilitates the transmission of goods between the cross-belt sorting machine 1 and the linear sorting machine 3, and the inverted-U-shaped conveying channel 2 facilitates the transmission of goods between adjacent linear sorting machines 3.

[0060] Of course, in this embodiment, it is only a preference to set the primary sorting device as the cross-belt sorting machine 1 and the secondary sorting device as the linear sorting machine 3. It can be imagined that the primary sorting device can also be a linear sorting machine, a narrow-belt sorting machine or a swing-wheel sorting machine, and the secondary sorting device can also be a narrow-belt sorting machine, a swing-wheel sorting machine or a slider sorting machine.

[0061] It should be noted that the express sorting system provided in this embodiment can be used separately with the cross-belt sorter 1 or the linear sorter 3 according to requirements. Specifically, when the cross-belt sorter 1 is turned on for separate use, the sorting outlet can be disabled for operation, or the sorting outlet can be configured as a grid for operation; when the linear sorter 3 is turned on for separate use, the sorting outlet can be disabled, and each linear sorter 3 can work independently, or the sorting outlet can be turned on, and multiple linear sorters 3 can work together.

[0062] Embodiment 2

[0063] The main difference between this embodiment and Embodiment 1 is that:

[0064] Multiple linear sorters are located inside the ring of the cross-belt sorter. A plurality of sorting outlets corresponding to the linear sorters one by one are arranged on the straight section of the cross-belt sorter near one end of the linear sorter; the express sorting system can be switched between a first mode and a second mode. When the express sorting system is in the first mode, the corresponding sorting outlet and the linear sorter are connected through a conveyor channel. When the express sorting system is in the second mode, adjacent linear sorters are connected through a conveyor channel to form a serpentine conveying path.

[0065] Compared with Embodiment 1, the express sorting system configured in this way has a higher space utilization rate and a smaller floor area.

[0066] The rest that is the same as Embodiment 1 will not be elaborated here.

[0067] Embodiment 3

[0068] The main difference between this embodiment and Embodiment 1 is that:

[0069] As Figure 3 shown, the cargo input port 31 of the linear sorter 3 is located on the side of the first end of the linear sorter 3, and the cargo output port 32 of the linear sorter 3 is located on the side of the second end of the linear sorter 3.

[0070] The rest that is the same as Embodiment 1 will not be elaborated here.

[0071] Embodiment 4

[0072] The main difference between this embodiment and Embodiment 1 is that:

[0073] As Figure 4As shown in the figure, the linear sorting machine 3 (i.e., on a secondary sorting layer) has two parcel input ports 31, namely the first parcel input port 311 and the second parcel input port 312. The first parcel input port 311 is located at the end of the first end of the linear sorting machine 3, and the second parcel input port 312 is located at the side of the first end of the linear sorting machine 3. On the cross-belt sorting machine 1, there are a first sorting outlet corresponding one-to-one to the first parcel input port 311 and a second sorting outlet corresponding one-to-one to the second parcel input port 312. When the express sorting system is in the first mode, the transfer channel 2 connects the corresponding first sorting outlet and the first parcel input port 311, and connects the corresponding second sorting outlet and the second parcel input port 312.

[0074] In this way, the two sorting outlets on the cross-belt sorting machine 1 correspond to one linear sorting machine 3 (i.e., one secondary sorting layer), further improving the sorting efficiency of the express sorting system.

[0075] Optionally, the linear sorting machine 3 has multiple parcel input ports 31. On the cross-belt sorting machine 1, there are sorting outlets corresponding one-to-one to the parcel input ports 31, and the transfer channel 2 connects the corresponding sorting outlets and the parcel input port 311.

[0076] For the parts that are the same as those in Embodiment 1, they will not be elaborated here.

[0077] Embodiment 5

[0078] Compared with Embodiment 1, Embodiment 2, Embodiment 3 or Embodiment 4, the main difference in this embodiment is that:

[0079] The cross-belt sorting machine is a double-layer cross-belt sorting machine, including two primary sorting layers arranged in sequence from top to bottom. On at least one primary sorting layer, there are multiple sorting outlets with a uniquely corresponding linear sorting machine; the express sorting system can switch between the first mode and the second mode. When the express sorting system is in the first mode, the transfer channel connects the sorting outlet with its corresponding linear sorting machine. When the express sorting system is in the second mode, the transfer channel connects adjacent linear sorting machines to form a snake-shaped conveying path.

[0080] Compared with Embodiment 1, the express sorting system arranged in this way has higher sorting efficiency, higher space utilization rate, and smaller floor area.

[0081] Specifically, in this embodiment, on each primary sorting layer, there are multiple sorting outlets with a uniquely corresponding linear sorting machine.

[0082] Optionally, the cross-belt sorting machine is a multi-layer cross-belt sorting machine.

[0083] The same parts as those in Embodiment 1, Embodiment 2, Embodiment 3, or Embodiment 4 will not be described herein again.

[0085] Compared with Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, or Embodiment 5, the main difference of this embodiment lies in that:

[0086] The linear sorting machine includes at least two secondary sorting layers arranged in sequence from top to bottom, and a conveying channel connects the sorting outlet with its corresponding secondary sorting layer.

[0087] The same parts as those in Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, or Embodiment 5 will not be described herein again.
