Description

Technical Field

[0001] The present invention relates to an RFID automatic picking cart capable of inspecting ordered products in real time, and particularly belongs to the technical field of picking.

Background Art

[0002] An RFID automatic picking cart is a conveyance tool installed with an RFID reader and used when a picking worker performs a picking operation in a warehouse. The picking worker takes out the corresponding products from the warehouse based on a picking list and puts them into the RFID automatic picking cart, and then transports all the products on the picking list to the location of the next process.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The current RFID automatic picking cart is only used as a conveyance tool for products and can only input the information of the taken-out products by the installed RFID reader. In other words, since it has no function of checking products, it can only passively input product information, and the picking worker can only manually check based on the picking list. When a mistake occurs, in order to verify whether the products in the RFID automatic picking cart match the products in the picking list, it has to rely on the subsequent provided verification procedures. Usually, in some large-scale warehouse centers, the types of stored products are very numerous. For example, in a clothing warehouse center, the colors, sizes, and types of clothing are different. Therefore, when relying only on manual verification, the error rate is high. Moreover, when the picking worker leaves during the picking process or the picking worker is replaced midway, the probability of mistakes is even higher.

[0004] The above is the risk of error that only exists in picking the goods for one order. When the picker uses one RFID automatic picking cart to pick the goods for multiple orders together, the error probability becomes even higher. There are not only the problems of mispicking the goods, but also the problem of separating the goods between orders. These problems are directly related to a series of problems such as the reduction of picking efficiency and the reduction of the order processing efficiency of the logistics sensor.

Means for Solving the Problem

[0005] In order to solve the problems of the prior art, the present invention provides an RFID automatic picking cart that can inspect the ordered goods in real time, without relying on the manual inspection of the ordered goods, and only the picker is the operator.

[0006] An RFID automatic picking cart that can inspect the ordered goods in real time, the RFID automatic picking cart is composed of a picking processor 11, an RFID reader and a corresponding RFID scanning area 12, and a printer 13. The RFID reader is used to read the RFID tag information of the goods placed in the RFID scanning area 12. The RFID reader and the printer 13 are connected to the picking processor 11 via a wireless LAN or a data transfer cable. The picking processor 11 stores in advance the storage location information of all the goods in the warehouse center, generates a corresponding distribution instruction based on the distribution task of the imported order, and inspects whether the ordered goods are correct based on the goods information read by the RFID reader.

[0007] Alternatively, the RFID automatic picking cart 1 has S (S≧1) container placement positions, and each container placement position is connected to the picking processor 11 via a signal line, and a display mark 16 is provided to notify the picker of the corresponding container placement position according to the distribution instruction.

[0008] Alternatively, the picking processor 11 is characterized in that it is also provided with a display unit.

[0009] Alternatively, the picking processor 11 is also provided with earphones and a voice dialogue system. The picking worker realizes information interaction with the picking processor 11 through the earphones and the voice dialogue system.

[0010] Alternatively, the RFID automatic picking cart 1 is also provided with a weighing sensor and / or a camera connected to the picking processor 11 via a wireless LAN or a data transfer cable. When it is provided with a weighing sensor, weighing sensors are respectively provided under S container placement positions. The picking processor 11 determines whether the picking worker has correctly put the goods based on the weight change of the corresponding container placement position. The weighing sensor transmits the weight sensed in real time via the data transfer cable to the picking processor 11. When it is provided with a camera, the camera is provided at a place where it can simultaneously photograph the S container placement positions above the RFID automatic picking cart according to the actual scenario, and determines whether the picking worker has correctly put the goods based on the AI image recognition result.

[0011] Alternatively, the RFID automatic picking cart 1 further includes a replaceable rechargeable battery 14 for supplying power to the picking processor 11, the RFID reader, the printer 13, the display mark 16, the weighing sensor and / or the camera.

[0012] Alternatively, the RFID automatic picking cart 1 further includes a frame body 15 provided with a single-stage or multi-stage structure according to the requirements of the actual application scenario.

[0013] Alternatively, the display mark 16 is a display lamp or an electronic bulletin board. When the RFID automatic picking cart performs allocation for a plurality of orders, the electronic bulletin board displays different marks so that the picking worker can distinguish each order.

[0014] Alternatively, the RFID automatic picking cart uses a multi-wheel structure including a three-wheel structure, a four-wheel structure, and a structure of three main wheels + two auxiliary wheels. In the structure of three main wheels + two auxiliary wheels, two main wheels and two auxiliary wheels are respectively located at the four corners of the bottom of the RFID automatic picking cart, with the main wheels in the front and the two auxiliary wheels in the rear, and the other main wheel is located between the two auxiliary wheels.

[0015] Alternatively, the RFID automatic picking cart is configured to include a robotic arm and a driving device. The picking processor 11 is equipped with an automatic navigation function. The robotic arm and the driving device are connected to the picking processor 11 via signal lines. The RFID automatic picking cart automatically completes allocation under the drive of the driving device based on navigation information.

Advantages of the Invention

[0016] The present invention provides an RFID automatic picking cart capable of inspecting ordered products in real time. The RFID automatic picking cart is composed of a picking processor, an RFID reader and a corresponding RFID scanning area, a printer, an earphone, and a plurality of container placement positions. A display mark is provided at each container placement position. The picking processor can pre-store the storage location information of all products in the warehouse center. After importing the distribution task information of the order into the picking processor, the picking processor generates a corresponding distribution instruction based on the distribution task so that the picking worker can complete the distribution according to the distribution instruction. During the distribution process, the picking processor ensures, as much as possible, the accuracy of the product pickup and input positions through the distribution instruction and the display mark, verifies the product information read by the RFID reader with the content of the issued instruction, realizes re-verification of the product pickup, and can also be provided with a weighing sensor and / or a camera to re-verify the input position of the product through weight detection or AI image recognition.

Embodiments for Carrying out the Invention

[0019] Hereinafter, to make the objectives, technical means, and advantages of the present invention clearer, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0020] (First Embodiment) This embodiment provides an RFID automatic picking cart capable of inspecting ordered products in real time. As shown in FIG. 1, the RFID automatic picking cart includes a picking processor 11, an RFID reader and a corresponding RFID scanning area 12 (the RFID reader is not shown in FIG. 1), a printer 13, and a display mark 16. The picking processor 11 includes a display unit, and the display unit can be an independent display unit connected to the picking processor 11 via a wireless LAN, a data transfer cable, or Bluetooth (registered trademark), or may be integrally formed with the picking processor 11. By controlling the reading distance of the RFID reader with an improved RFID antenna, only the products placed within the RFID scanning area 12 can be read without misreading the products on the product shelves, and multiple products can also be scanned simultaneously. The RFID reader and the printer 13 can be connected to the picking processor 11 via a wireless LAN or a data transfer cable. The display mark 16 is connected to the picking processor 11 via a signal line.

[0021] In actual applications, the picking processor 11 can be a mobile handheld terminal such as a tablet, or a stationary computer provided on the RFID automatic picking cart. An input keyboard and a display can be provided according to actual needs, and the display unit can also be a movable interactive display unit.

[0022] The RFID automatic picking cart 1 is also equipped with a voice dialogue system and earphones. The picking worker can conduct simple voice dialogue with the picking processor 11 through the earphones. The earphones can be wired earphones, Bluetooth (registered trademark) earphones or other wireless earphones according to the actual scenario. The picking processor 11 generates corresponding distribution instructions based on the distribution tasks of the imported orders and prompts the picking worker to perform corresponding operations through the earphones.

[0023] The RFID automatic picking cart 1 further includes a frame body 15 provided in a one-stage or multi-stage structure according to the requirements of the actual application scenario. In FIG. 1, as an example, it is provided in a two-stage structure, has S container placement positions, and display marks 16 are provided at each container placement position. The display mark 16 can be a display lamp or an electronic bulletin board, and notifies the picking worker of the corresponding product input position according to the distribution instructions issued by the picking processor 11.

[0024] The RFID automatic picking cart 1 is further configured to include a replaceable rechargeable battery 14 for supplying power to the picking processor 11, the RFID reader, the printer 13, the display mark 16, etc.

[0025] When distributing for multiple orders, considering the possibility that goods may be mistakenly placed in containers corresponding to other orders, the RFID automatic picking cart 1 is also equipped with a weighing sensor and / or a camera. When including a weighing sensor, weighing sensors are respectively provided under the S container placement positions. The picking processor 11 determines whether the picking worker has correctly placed the goods based on the weight change of the corresponding container placement position. The weighing sensor transmits the weight sensed in real time via a data transfer cable to the picking processor 11. When including a camera, according to the actual scenario, the camera is provided at a place where it can simultaneously photograph the S container placement positions above the RFID automatic picking cart, and determines whether the picking worker has correctly placed the goods based on the AI image recognition result. The weighing sensor and / or the camera are not shown in FIG. 1.

[0026] The picking processor 11 pre-stores the storage location information of all goods in the warehouse center. Before distributing using the RFID automatic picking cart 1, it is necessary to import the distribution task information into the picking processor 11. The distribution task includes the goods information for multiple orders required for processing. The picking processor 11 generates the corresponding distribution instruction based on the distribution task, enabling the picking worker to complete the distribution according to the distribution instruction. Specifically, taking the RFID automatic picking cart 1 shown in FIG. 1 with six (S = 6) container placement positions and the distribution task also including six orders as an example, it will be described below.

[0027] After the picking worker enters their employee number ID and clicks "Start Distribution" on the interactive display unit, the picking processor 11 issues a distribution instruction, prompting the picking worker to take the corresponding specification containers for Orders 1 to 6 and place them at the corresponding container placement positions. For example, when there is a distribution instruction such as "Take a Type A container and place it at the first position in the upper row", the indicator light at the first position in the upper row of the RFID automatic picking cart lights up, instructing the picking worker to place the Type A container at this location.

[0028] During the distribution process, the picking processor 11 gives a distribution instruction to the picking worker, saying "Please drive to the P-th location on the product shelf in the first row", and after the picking worker arrives at the location, he / she can respond "Arrived" via the voice dialogue system. At this time, the picking processor 11 gives a distribution instruction "Please pick up 3 pieces of product B". The picking worker places 3 pieces of product B in the RFID scanning area 12 from the location. At this time, the RFID reader reads the product information, displays the result on the screen and announces the corresponding voice instruction. If the product information is incorrect, it will inform of specific mistakes such as insufficient quantity, excessive quantity or picking the wrong product. For example, if the picking worker only picks up 2 pieces, after the RFID reader reads the product information, the picking processor 11 will give an instruction "2 pieces of product B have been picked up, but please pick up 1 more piece" after verification. If the product information is correct, it will give a distribution instruction "Please place 3 pieces of product B3 at the first position in the upper layer" and the indicator light at the first position in the upper layer of the RFID automatic picking cart 1 will light up. If the picking worker does not place it at the corresponding position, the RFID automatic picking cart can also issue a notification. This function is realized by using a weighing sensor and / or a camera.

[0029] During the above distribution process, the picking processor ensures the accuracy of the picking and input position of the product by the picking worker through the distribution instruction and the display mark, collates the product information read by the RFID reader with the content of the issued instruction, realizes the re-verification of the product picking, and can re-verify the input position of the product by weight detection or AI image recognition. Therefore, the RFID automatic picking cart ensures the distribution accuracy to the maximum extent.

[0030] In addition, by installing the interactive display unit, the progress of distribution is displayed in real time, and there are corresponding voice instructions. Even if the picking worker leaves and returns during the distribution process, the distribution can be continued, and there is no need to take over the distribution status when replacing the picking worker, enabling seamless continuation of the distribution.

[0031] When the picking processor 11 detects that the container at a specific position is full (which can be determined based on the container specifications and the information of the goods placed in it), it notifies the picking worker with the message "The container is full. Do you need to print the case code?", and the picking worker can select "Print case code" through the interactive display unit or the voice dialogue system. The picking processor 11 issues a print command for the case code to the printer 13. The case code includes all the product information and corresponding order information in the container, and at the same time, it is noted on the case code which container of the corresponding order it is.

[0032] After the printing of the case code is completed, the picking processor 11 attaches the case code to the container at the corresponding position (informs the picking worker of the corresponding position through the display mark 16), and prompts the picking worker to store it at the nearest unpacking area 7 after packing and sealing. The unpacking area 7 can be installed at a location at one end of the aisle of the product shelf. In the unpacking area 7, there are also empty boxes (the packed and sealed containers and empty boxes may be placed on different pallets respectively) so that the picking worker can place the sealed container at this location and then take an empty box to continue the distribution.

[0033] When the picking processor 11 detects that all pickups of the products for a certain order (assumed to be Order 1) are completed regardless of whether the last container is full (in the distribution plan, the container of the appropriate specification is usually determined based on the order size, but the container may not be exactly full), it notifies the picking worker with the message "The distribution of the order is completed. Please print the case code." The picking worker follows the notification to print the case code, affix the case code to the corresponding container, and store it at the nearest shipping yard 7 after packing and sealing.

[0034] After the picking worker arrives at the last picking unit of the distribution task and completes the distribution at the picking location, the picking processor 11 checks whether the ordered product is out of stock. If there is no out-of-stock situation, the picking processor 1 returns to the initial state until the picking worker clicks "Start Distribution" on the interactive display to enable a new distribution task.

[0035] During the distribution process, if a picking worker notices that the stock of a product required for an order is out of stock, the picking processor 11 transmits "stock replenishment required information" to the data processing center of the warehouse center through the picking processor 11. The stock replenishment information includes the number of out-of-stock items and the order information corresponding to the out-of-stock product. The data processing center immediately notifies the warehouse manager of the stock replenishment. After the warehouse manager completes the stock replenishment, the data processing center transmits stock replenishment completion information. After receiving the stock replenishment completion information, the data processing center changes the status of the above "stock replenishment required information" to the "completed" status. After transmitting the stock replenishment required information, the picking processor 11 continues to prompt the picking worker to pick up the remaining products included in the order. After all the distribution tasks for all orders in the distribution task are completed, the picking worker can click "distribution completed" on the interactive display unit. After the picking processor 11 receives the click information, it checks whether there is an order in an out-of-stock state. If so, it reads the status of the "stock replenishment required information" transmitted by the data processing center. If it is the "completed" status, the picking processor 11 goes to the corresponding location to complete the distribution of the out-of-stock product and subsequent operations such as case code printing and sealing, and prompts the picking worker to store it in the nearest sorting area 7. If the status of the "stock replenishment required information" is "pending processing", the picking processor 11 records the out-of-stock information, and then prompts the picking worker to place the container in the corresponding area (it is also possible to set an out-of-stock area near the sorting area 7) for the stock replenishment staff to process together, and at the same time uploads the out-of-stock information to the data processing center.

[0036] In addition to completing the above distribution task, the picking processor 11 immediately monitors the remaining battery level, the status of the printer paper, and the presence or absence of a failure of the indicator light. If an abnormality occurs, it displays the abnormality information on the interactive display unit.

[0037] When a picking worker picks using the RFID automatic picking cart 1, it only functions as the executor of actions such as picking up a product, placing a product, attaching a case code, pressing a button, packing a container, placing a container, and pushing the cart. Therefore, the RFID automatic picking cart 1 can also complete the execution of the above actions by installing a robotic arm. The picking processor 11 is equipped with an automatic navigation function. The RFID automatic picking cart 1 is equipped with a driving device and automatically completes distribution under the drive of the driving device according to the navigation information.

[0038] The RFID automatic picking cart 1 is provided with a general three-wheel structure or four-wheel structure according to the actual application scenario. In addition to the general three-wheel structure or four-wheel structure, a structure of 3 main wheels + 2 auxiliary wheels can also be used. As shown in FIG. 2, the 2 main wheels and the 2 auxiliary wheels are respectively located at the four bottom corners of the RFID automatic picking cart. The main wheels are in the front, the 2 auxiliary wheels are in the back, and the other main wheel is located between the 2 auxiliary wheels. The 2 main wheels in the front use fixed wheels, and the main wheel in the back can use a swivel wheel for the picking worker to easily change the direction of the RFID automatic picking cart 1. The 2 auxiliary wheels in the back play a role in supporting the cart, preventing the cart from tipping over and facilitating direction change.

[0039] Some steps in the embodiments of the present invention can be implemented by software, and the corresponding software program can be stored in a readable storage medium such as an optical disk or a hard disk.
