Description

Technical Field

[0001] This utility model relates to the technical field of warehousing and logistics, and more specifically to a cargo handling system. Background Technology

[0002] Currently, logistics warehousing utilizes inclined conveyor systems to store goods. Picking mechanisms retrieve orders from these systems, and replenishment mechanisms replenish the stock. This is commonly seen in vending machines and pharmaceutical vending machines. Inclined conveyor systems are unidirectional; goods can only enter from one end and exit from the other. Therefore, to facilitate picking by the mechanism, the same SKU (Stock Keeping Unit) is typically stored within the same inclined conveyor. When the inventory is less than the predetermined quantity, the replenishment mechanism needs to add stock from one side of the shelf into the inclined conveyor. This limits the application scope and efficiency of the picking mechanism, and also affects the storage density of goods on the shelves. Utility Model Content

[0003] To overcome the aforementioned technical deficiencies, this utility model provides a cargo handling system, comprising:

[0004] The shelf is provided with multiple inclined aisles arranged at intervals to store goods. Each inclined aisle has an entrance and an exit, with the entrance being higher than the exit.

[0005] A picking mechanism, movably arranged along the length of the shelf relative to one side of the shelf and adjacent to the exit, retrieves goods from the exit of the target inclined aisle;

[0006] An order conveying device is used to transport goods from the picking mechanism to a packing machine for packing;

[0007] A return conveyor for transporting goods from the picking mechanism to the return mechanism; and

[0008] A return mechanism, movably arranged along the length of the shelf relative to the other side of the shelf and adjacent to the entrance, is used to feed goods from the return conveyor through its entrance into a predetermined inclined aisle.

[0046] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] like Figure 1As shown, the cargo handling system 100 according to an embodiment of the present invention includes a shelf 101 with multiple inclined aisles 1011, a picking mechanism 102, a return mechanism 103, an order conveying device 104, and a return conveying device 105. The multiple inclined aisles 1011 are arranged vertically and horizontally at intervals on the shelf 101. Each inclined aisle 1011 has an inlet and an outlet, with the inlet positioned higher than the outlet. Goods are stored on the inclined aisles 1011. When goods are retrieved, they slide out of the inclined aisles 1011 by gravity. The picking mechanism 102 is used to retrieve goods from the inclined aisles 1011 of the shelf 101, deliver ordered goods to the order conveying device 104, and deliver returned goods to the return conveying device 105. The order conveying device 104 is used to transport ordered goods... The goods are sent to the packing machine 107 for packing and shipping. The return conveyor 105 is used to send the return goods on the target inclined aisle of the target shelf to the return mechanism 103. The return mechanism 103 sends the return goods back to the predetermined inclined aisle of the predetermined shelf. Here, the target inclined aisle and the predetermined inclined aisle can be the same aisle or two different aisles, and can be located on the same shelf or on different shelves. The goods include at least one of the ordered goods and the return goods. Ordered goods refer to the goods corresponding to the order information. Return goods refer to other goods besides the ordered goods, including any return goods transferred within the shelf and between different shelves, such as goods that need to be returned to the shelf for rearrangement in the case of picking, inventory, sorting, and abnormal goods. The order conveyor 104 and the return conveyor 105 can be configured as a conveyor line.

[0048] In some embodiments, such as Figure 1 and 2 As shown, the picking mechanism 102 includes a transfer warehouse 1021, a storage warehouse, and a traveling device 1024. The traveling device 1024 is movable along the side of the rack 100 adjacent to the exit of the inclined aisle 1011. The transfer warehouse 1021 is liftable relative to the traveling device 1024 to receive goods from the exit of the target inclined aisle 1011. The transfer warehouse 1021 is located between the inclined aisle 1011 and the storage warehouse. The transfer warehouse 1021 is selectively connected to the storage warehouse via lifting. There can be one or more storage warehouses. In the case of a single storage warehouse, the warehouse selectively delivers goods to the order conveyor 104 and the return conveyor line 105. In the case of multiple warehouses, the transfer warehouse 1021 is movable to selectively connect with one of the multiple warehouses, including a first warehouse 1022 and a second warehouse 1023. The first warehouse 1022 is used to receive returned goods for returning them to the shelves, and the second warehouse 1023 is used to receive order goods for delivering them to the order conveyor 104. The first warehouse 1022 and the second warehouse 1023 can be arranged vertically or vertically, or they can be arranged in a fixed position.

[0049] In some embodiments, such as Figure 1As shown, the cargo handling system 100 also includes a packing machine 107 and a temporary storage station 106. The temporary storage station 106 is located downstream of the order conveying device 104, between the packing machine 107 and the order conveying device 104, and is used to store order goods waiting to be packed. The temporary storage station 106 has multiple inclined storage positions 1061 arranged vertically, with its entrance higher than its exit. Liftable inlet devices 1062 and outlet devices 1063 are arranged on both sides of the temporary storage station 106. The liftable inlet device 1062 is arranged on the entrance side of the temporary storage station 106 and is used to send the order goods conveyed by the order conveying device 104 into the entrance of the storage position 1061. The liftable outlet device 1063 is arranged on the exit side of the storage position 1061 and is used to receive the order goods from the exit of the storage position 1061 and send them into the packing machine 107. The packing machine 107 packs the order goods, and then the packed order goods are shipped out through logistics. Alternatively, the temporary storage station 106 can be omitted, and the order conveying device 104 can directly deliver the order goods to the packing machine 107 for packing. Optionally, the liftable inlet mechanism 1062 can be a liftable diverter, and the liftable outlet device 1063 can be a liftable conveyor belt.

[0050] In some embodiments, such as Figure 2 and 3 As shown, the cargo handling system includes a first image acquisition device 1026, which uses image recognition technology to identify information about goods entering the temporary storage warehouse 1021 to determine whether the goods are order goods. After the goods are identified as order goods, the transfer warehouse 1021 moves to the second warehouse 1023 and allocates the order goods to the second warehouse 1023. After the goods are identified as return goods, the transfer warehouse 1021 moves to the first warehouse 1022 and allocates the return goods to the first warehouse 1022. Both the first warehouse 1022 and the second warehouse 1023 have openable and closable baffles 1025 to allow and prevent goods from leaving. The first image acquisition device 1026 can be located near the temporary storage warehouse 1021 or in other locations, as long as it can identify information about goods entering the temporary storage warehouse 1021.

[0051] In some embodiments, the first warehouse 1022 and the second warehouse 1023 are arranged to simultaneously dock with the return conveyor 105 and the order conveyor 104, respectively, so as to transfer the corresponding goods to the corresponding conveyor and complete the transfer of order goods and return goods at the same time.

[0052] In some embodiments, the cargo handling system 100 has an order mode and a return mode, and is capable of executing the order mode and the return mode respectively.

[0053] The order process includes the following steps:

[0054] Based on order information and cargo storage information, the transfer warehouse 1021 is instructed to move to the target inclined conveyor 1011 of the shelf to retrieve and receive cargo from the exit of the inclined conveyor 1011.

[0055] The first image acquisition device 1026 uses image recognition technology to identify whether the goods are the goods in the order;

[0056] If so, instruct transfer warehouse 1021 to allocate the order goods to the second warehouse 1023;

[0057] If not, instruct transfer warehouse 1021 to allocate the goods to first warehouse 1022.

[0058] The order process includes the following steps:

[0059] According to the return instruction and cargo storage information, the picking mechanism 1021 is instructed to move to the target inclined cargo channel 1011 and take out the returned cargo, send the cargo to the first warehouse 1022, and then send the cargo to the return mechanism 103 through the return conveyor 105.

[0060] Instruct the return mechanism 103 to deliver these goods to the designated inclined cargo channel 1011;

[0061] In the return flow mode, the cargo handling system 100 transfers the return cargo in the target inclined aisle 1011 sequentially through the transfer warehouse 1021, the warehouse, the return conveyor 105, and the return mechanism 103 to the predetermined inclined aisle 1011. This realizes the redistribution of the cargo in the target inclined aisle 1011 to the predetermined inclined aisle. During the return flow mode, no cargo is sent to the order conveyor line 104. The transfer of cargo is carried out within the same shelf and between different shelves. The cargo is not sent out of the shelf, thus completing the rearrangement of the cargo on the shelf.

[0062] Order information includes at least the buyer, product name, model, and quantity. Goods storage location information includes at least the location of each shelf, the location of each tilt aisle within each shelf, and the name, model, quantity, and location of each item stored in each tilt aisle. Return information includes at least the locations of the target tilt aisle and the intended tilt aisle. The purpose of return is to transfer returned goods from the target tilt aisle to the intended tilt aisle. Returned goods can be some or all of the goods in the target tilt aisle, and the intended tilt aisle can be any tilt aisle. Goods are identified based on order information, categorizing them as ordered goods and non-ordered goods. Non-ordered goods need to be transferred back to the shelf and are also considered returned goods. Based on the return information, it is determined which goods in the target tilt aisle are returned goods.

[0063] In some embodiments, the goods handling system 100 can execute order mode and return mode separately and simultaneously. When the goods handling system 100 executes order mode and return mode separately, the steps of order mode and return mode are executed separately; when the goods handling system 100 executes order mode and return mode simultaneously, the steps of order mode and return mode are executed in combination. The second warehouse 1023 collects ordered goods, and the first warehouse 1022 collects both non-order goods and returned goods. Both order mode and return mode require the first warehouse 1022. On the one hand, in order mode, ordered goods are sent to the order conveying device 104 through the second warehouse 1023 and then to the packing machine 107 for packing, and returned goods are returned to the shelf through the first warehouse 1022. On the other hand, in return mode, returned goods are redistributed within the shelf. This achieves parallel operation of multiple tasks and improves the efficiency of goods handling.

[0064] In some embodiments, such as Figure 4 As shown, multiple spaced shelves 101 can be set up, with an aisle formed between every two adjacent shelves 101. The inclined aisles 1011 in two adjacent shelves 101 are arranged symmetrically with respect to the aisle. Only one picking mechanism 102 or one return mechanism 103 is set up in each aisle. The picking mechanism 102 and the return mechanism 103 are arranged alternately in multiple aisles. In this way, two adjacent shelves 101 can share one picking mechanism 102 or one return mechanism 103. One picking mechanism 102 can retrieve goods from two adjacent shelves 101, and one return mechanism 103 can replenish goods to two adjacent shelves 101, which increases the effective storage space of the warehouse and improves the efficiency of goods handling.

[0065] In some embodiments, such as Figure 1 and 4 As shown, the return mechanism 103 includes a traveling device 1031, a picking device 1032, a second image acquisition device 1033, and a return inclined slide 1034 that is vertically mounted on the traveling device 1031. The traveling device 1031 can move along the side of the shelf 101 adjacent to the entrance of the inclined aisle 1011. The picking device 1032 is used to grab returned goods from the return conveyor 105, and the second image acquisition device 1033 identifies the information of the goods, and then puts the goods into the return inclined slide 1034. According to the replenishment information, the return inclined slide 1034 moves to the entrance of the predetermined inclined slide 1011, and puts the goods into the predetermined inclined slide 1011 through the entrance. Optionally, as Figure 5As shown, the outlet of the return inclined slide 1034 is provided with a liftable stop 1035 to allow and block goods from leaving; the picking device 1032 may include a suction cup for picking up goods and transferring them to the return inclined slide 1034; the return mechanism 103 may also include a temporary storage rack 1036 for temporarily storing goods to be placed into the return inclined slide 1033. Optionally, the picking device 1032 may be omitted, and goods on the return conveyor 105 may be picked up by other means, such as manually.

[0066] According to another aspect of the present invention, a cargo handling method based on the above-described cargo handling system is also provided, comprising:

[0067] Based on at least one of the order information and return information, as well as the cargo storage location information, the target inclined conveyor 1011 where the target cargo is located is determined. The picking mechanism 102 is instructed to move to the target inclined conveyor 1011, and the picking mechanism 102 retrieves the cargo from the exit of the target inclined conveyor 1011. The target cargo includes at least one of the ordered cargo and the returned cargo.

[0068] Instruct pickup unit 102 to perform at least one of the following:

[0069] The order goods are delivered to the order conveyor 104 for transport toward the packing machine 107;

[0070] The returned goods are sent to the return conveyor 105;

[0071] The return mechanism 103 is instructed to send the returned goods from the return conveyor 105 into the predetermined inclined conveyor 1011.

[0072] In some embodiments, the goods handling method includes the following steps in executing an order mode:

[0073] Based on the order information, the first image acquisition device 1026 of the pickup mechanism 102 can use image recognition technology to identify whether the goods retrieved from the exit are the ordered goods.

[0074] If so, the picking mechanism 102 is instructed to deliver the order goods to the second warehouse 1023, and then the order goods in the second warehouse 1023 are sent to the order conveying device 104. The order goods are then sent by the order conveying device 104 to the packing machine 107 for packing and shipping.

[0075] If not, instruct the picking mechanism 102 to deliver the returned goods to the first warehouse 1022, and then send the returned goods in the first warehouse 1022 to the return conveyor 105.

[0076] Based on order information, ordered goods are removed from the shelves, packaged, and shipped out, while other returned goods are sent back to the shelves, thus achieving a return process.

[0077] In some embodiments, under order mode, the return goods in the first warehouse 1022 and the order goods in the second warehouse 1023 are simultaneously transferred to the return conveyor 105 and the order conveyor 104, respectively, thereby improving the transfer efficiency of goods.

[0078] In some embodiments, such as Figure 1 As shown, the cargo handling method includes the following steps in implementing a return mode:

[0079] Based on the return information, the picking mechanism 102 is instructed to deliver the returned goods in the target inclined conveyor 1011 to the return conveyor 105; and

[0080] The return mechanism 103 delivers the returned goods from the return conveyor 105 to the predetermined inclined conveyor 1011.

[0081] This allows for the transfer and rearrangement of goods within the shelving system based on return information.

[0082] In some embodiments, the cargo handling method can simultaneously execute order processing mode and return flow mode steps, meaning that order processing mode and return flow mode steps can be mixed and executed. This enables multi-task processing simultaneously, improving cargo handling efficiency.

[0083] In some embodiments, the cargo handling method includes:

[0084] The picking mechanism 102 is instructed to retrieve the goods from the target inclined conveyor 1011;

[0085] Based on the order information, the information of each item entering the pickup facility 102 is identified one by one to determine whether the item is part of the order; and

[0086] Ordered goods are delivered to the second warehouse 1023 and order conveying device 104 of the picking mechanism 102, and returned goods are delivered to the first warehouse 1022 and return conveying device 105 of the picking mechanism 102.

[0087] This way, even if there are errors in the cargo storage location information or unexpected situations occur during the pickup process, the accuracy of the order can still be guaranteed and will not be affected by other errors.

[0088] In some embodiments, the cargo handling method includes:

[0089] Based on the specific cargo information recorded in the target inclined cargo channel, the picking mechanism 102 is instructed to continuously retrieve multiple non-target cargo items from the target inclined cargo channel 1011. These non-target cargo items are returned cargo items. These multiple non-target cargo items are then sent together to the first warehouse 1022. The target cargo item is then retrieved. This target cargo item is recorded as an order item in the cargo storage information. Image recognition technology is used to verify whether the target cargo item is an order item.

[0090] Thus, the target goods are allocated to the second warehouse 1023 and sent to the order conveying device 104, while the non-target goods in the first warehouse 1022 are sent to the return conveying device 105.

[0091] If not, the target goods are sent to the first warehouse 1022, all goods in the first warehouse 1022 are sent to the return conveyor 105, and the information of the remaining goods in the target inclined conveyor 1011 is updated and stored in the goods storage information.

[0092] This allows for continuous operation on non-target goods preceding the target goods based on pre-stored information about the goods' storage location, while only identifying and verifying the target goods. This maximizes retrieval efficiency. If the target goods are not part of the order, all retrieved goods are sent to the return conveyor 105 for re-placement in the shelf 101. Furthermore, the information of the remaining goods in the target inclined conveyor 1011 is re-recorded and updated to correct any errors in the pre-stored information.

[0093] According to another aspect of this utility model, such as Figure 6 As shown, this utility model provides a cargo handling apparatus 200, including: a memory 201 and a processor 202 coupled to the memory. The processor 202 is configured to instruct the cargo handling system to execute the aforementioned cargo handling method based on instructions stored in the memory 201. The memory 201 may include, for example, system memory, fixed non-volatile storage medium, etc. The system memory stores, for example, an operating system, application programs, a bootloader, and other programs.

[0094] The above description is only an exemplary embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
