Description

Technical Field

[0001] This utility model relates to the field of logistics sorting technology, and in particular to a picking workstation and picking system. Background Technology

[0002] In related technologies, robotic picking systems adopt a "goods-to-person" approach, where operators wait at the picking station for carts to bring boxes and other items to the workstation before picking them. However, existing picking workstations lack space for monitors or keyboards. These items are typically mounted on brackets directly in front of the picker, obstructing the movement of empty boxes from the carts and making them difficult to access. Furthermore, the current structure of picking workstations is often poorly designed, hindering improvements in picking efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a picking workstation and picking system that provides space for picking items, facilitates the loading and unloading of empty boxes from the trolley, and improves picking efficiency.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] Picking workstations include:

[0006] A workbench, which forms a trolley passage, has a picking surface, and a picking opening that penetrates the picking surface and is connected to the trolley passage.

[0007] A position detection device is installed in the trolley channel and located below the picking table. The position detection device is used to detect the position of the material box when the trolley lifts the material box to the picking port.

[0008] A barcode scanning mechanism is installed in the trolley channel and located below the picking table. The barcode scanning mechanism and the position detection device are distributed along the height direction of the worktable. The barcode scanning mechanism is used to scan the box code on the box when the position detection device detects that the box has arrived at the picking port.

[0032] like Figures 1 to 3As shown, this utility model embodiment provides a picking workstation 100, including a workbench, a position detection element 20, and a barcode scanning mechanism 30. The workbench has a trolley passage 101 and a horizontally arranged picking table surface 11. A picking port 111 is provided on the picking table surface 11, which is connected to the trolley passage 101. The position detection element 20 and the barcode scanning mechanism 30 are both arranged in the trolley passage 101 and located below the picking table surface 11, and are distributed along the height direction of the workbench. The position detection element 20 is used to detect the position of the material box 300 when the trolley 200 lifts the material box 300 to the picking port 111. The barcode scanning mechanism 30 is used to scan the box code on the material box 300 when the position detection element 20 detects that the material box 300 has arrived at the picking port 111. When the trolley 200 receives a picking task, it will carry the tin box 300 along the set path to the target position in the trolley channel 101, that is, the position directly opposite the picking port 111. Then the trolley 200 will lift the tin box 300 to the picking port 111. At this time, the position detection unit 20 will detect that the trolley 200 has lifted the tin box 300 to the position of the picking port 111. Then the barcode scanning mechanism 30 will scan the box code on the tin box 300 and compare it with the picking task issued by the system. If the comparison is successful, the picking personnel can pick the materials in the tin box 300 through the picking port 111. By setting up the picking table 11, space can be provided for the items to be picked; by setting up the trolley passage 101 and opening the picking port 111 on the picking table 11 that is connected to the trolley passage 101, it is convenient for picking personnel to pick items and to take and put empty material boxes 300 from the trolley 200; by arranging the barcode scanning mechanism 30 and the position detection component 20 along the height of the workbench, the picking personnel can first receive the prompt that the material box 300 has been lifted into place, and then receive the scanning result of the barcode scanning mechanism 30. This allows the picking personnel to start preparing for picking after receiving the prompt that the trolley 200 has arrived at the picking position, and can start picking immediately after receiving the scanning result, thus improving picking efficiency.

[0033] In this embodiment, the position detection element 20 is located below the scanning mechanism 30, and the detection direction of the position detection element 20 is inclined upward, that is, the detection direction of the position detection element 20 is distributed at an angle to the horizontal plane. This arrangement allows for more flexible placement of the position detection element 20 along the height of the worktable, eliminating the need for the position detection element 20 to be directly aligned with the position of the hopper 300 after it has been lifted into position, thus providing sufficient installation space for the scanning mechanism 30 (which must be directly aligned with the position of the hopper 300 after it has been lifted into position). In other embodiments, the detection direction of the position detection element 20 can also be parallel to the horizontal direction. In this case, the position detection element 20 can be located either above or below the scanning mechanism 30, but it is necessary to ensure that both the position detection element 20 and the scanning mechanism 30 are directly aligned with the position of the hopper 300 after it has been lifted into position.

[0034] In this embodiment, the position detection element 20 is a diffuse reflection sensor or a photoelectric sensor. The structure and working principle of diffuse reflection sensors and photoelectric sensors are existing technologies and will not be described in detail here.

[0035] The specific structure of the scanning mechanism 30 is existing technology and will not be described in detail here.

[0036] In this embodiment, the workbench includes a lower frame 12, a front partition, and a rear partition 15. A picking table 11 is mounted on the lower frame 12, which provides support for the picking table 11. The front partition is located on the side of the lower frame 12 closest to where the picking personnel stand, and the rear partition 15 is located on the side of the lower frame 12 furthest from where the picking personnel stand. A cart passage 101 is formed between the front and rear partitions. The front partition isolates the picking personnel's standing area from the cart passage 101 to prevent the picking personnel's legs from entering the cart passage 101 and causing safety hazards, thus ensuring the safety of the picking personnel. The rear partition 15 isolates the cart passage 101 from the robot area, preventing other carts 200 from accidentally entering the cart passage 101 and colliding with the carts 200 already in the cart passage 101.

[0037] In this embodiment, the lower frame 12 has a recessed opening on the side near where the picker stands, extending towards the trolley passage 101. The front partition includes a first front partition 13 and two second front partitions 14. The first front partition 13 is located at the bottom of the recess, and the two second front partitions 14 are respectively located on both sides of the recess. When performing picking operations, the picker can stand inside the recess, allowing them to be closer to the picking opening 111, facilitating the picking of goods in the bin 300 at the picking opening 111. In addition, the edges on both sides of the picking table 11 protrude from the recess to ensure that the picking table 11 has a large table surface area for placing other items.

[0038] In this embodiment, the workbench also includes an upper frame 16, a first protective plate 17, and two second protective plates 18. The upper frame 16 is disposed on the picking table surface 11. The first protective plate 17 and the two second protective plates 18 are both disposed on the upper frame 16. The first protective plate 17 is located on the side of the picking table surface 11 away from where the picking personnel stand. The two second protective plates 18 are respectively located on the two sides of the picking table surface 11 adjacent to where the picking personnel stand. The first protective plate 17 and the two second protective plates 18 surround the circumferential edge of the picking table surface 11. That is, the first protective plate 17 and the two second protective plates 18 surround the edges of the picking table surface 11 other than the standing picking personnel, to prevent the picking personnel from climbing over into the cart area and to protect the safety of the picking personnel. Furthermore, the first protective plate 17 and the second protective plate 18 are both made of transparent materials, such as acrylic, to facilitate the picking personnel's observation of the surrounding environment.

[0039] Furthermore, an illumination element 70 is provided on the upper frame 16. The illumination element 70 is located above the picking table 11 and can illuminate the picking table 11, which is more conducive to picking personnel.

[0040] The picking workstation 100 provided in this embodiment of the utility model also includes a prompting element 40, which is disposed on the picking table surface 11 and is communicatively connected to the position detection element 20 and / or the barcode scanning mechanism 30. When the position detection element 20 detects that the trolley 200 has arrived and / or the barcode scanning mechanism 30 scans the code and successfully compares it with the picking task issued by the system, the prompting element 40 issues a prompt to alert the picking personnel. Optionally, the prompting element 40 can be an indicator light. For example, when the position detection element 20 detects that the trolley 200 has arrived at the picking position and / or the barcode scanning mechanism 30 scans the code and successfully compares it with the picking task issued by the system, the indicator light displays, for example, green. When the position detection element 20 detects that the trolley 200 has not arrived at the picking position or although it detects that the trolley 200 has arrived at the picking position, but the comparison result of the barcode scanning mechanism 30 is unsuccessful, the indicator light displays, for example, red, so that the picking personnel can intuitively know whether to perform picking. Alternatively, the prompt 40 can also be a sound-emitting component, that is, to provide a prompt by emitting a sound.

[0041] The picking workstation 100 provided by this utility model also includes a display 51. The display 51 is mounted above the picking table surface 11 via a first adjusting bracket 61, which is configured to adjust the height and angle of the display 51. The display 51 is communicatively connected to the position detection element 20 and / or the barcode scanning mechanism 30, and can display the detection results of the position detection element 20 and / or the scanning results of the barcode scanning mechanism 30. By setting the first adjusting bracket 61, the position of the display 51 can be flexibly adjusted, improving the user experience, while preventing the display 51 from interfering with the picking and placing of the material box 300 from the picking port 111. The first adjusting bracket 61 can be a combined rocker arm, which is an existing structure and will not be described in detail here.

[0042] The picking workstation 100 provided by this utility model also includes a keyboard 52, which is mounted above the picking table surface 11 via a second adjusting bracket 62. The second adjusting bracket 62 is configured to adjust the height and angle of the keyboard 52. By setting the second adjusting bracket 62, the position of the keyboard 52 can be flexibly adjusted, improving the user experience, while preventing the keyboard 52 from interfering with the loading and unloading of the material box 300 from the picking port 111. The second adjusting bracket 62 can be a combined rocker arm, which is an existing structure and will not be described in detail here.

[0043] The picking workstation 100 provided by this utility model also includes a mouse 53 and / or a printer 80 and / or a handheld barcode scanner 90 placed on the picking table 11. Of course, other items can also be placed on the picking table 11, depending on the picking needs, and are not limited to this embodiment.

[0044] like Figure 4 As shown, this utility model embodiment also provides a picking system, including a trolley 200, a shelf 400 and the aforementioned picking workstation 100. The trolley 200 can travel along the trolley passage 101 to a position facing the picking port 111 and can lift the material box 300 to the picking port 111. The shelf 400 is located on the side of the picking personnel standing in the picking workstation 100 and is used to place the sorted materials.

[0045] The picking process of the picking system provided by this utility model is as follows:

[0046] After receiving the picking task, the trolley 200 carries the tote box 300 along the set path to the picking workstation 100 and enters the trolley passage 101;

[0047] After the trolley 200 reaches the position directly opposite the picking port 111, it lifts the material box 300 to the picking port 111.

[0048] Position detection 20 detected that the cart 200 had arrived at the picking position;

[0049] The barcode scanning mechanism 30 scans the box code on the material bin 300 and compares it with the picking task issued by the system;

[0050] After a successful comparison, indicator 40 will issue a notification to remind you that a picking task has been completed.

[0051] Pickers pick materials according to the picking task displayed on monitor 51 and place the picked materials into the target bins on shelf 400.

[0052] After completing the picking, the picker presses the confirmation button and reports the completion status.

[0053] The system issues a departure command to car 200.

[0054] In this embodiment, the confirmation button is located on the first front partition 13 or the second front partition 14 to facilitate operation by the picking personnel.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
