Description

Technical Field

[0001] This utility model relates to the field of catering equipment technology, specifically to a plate binding device for a unit member canteen. Background Technology

[0002] In catering establishments with on-demand meal payment systems, such as company canteens, users need to bind their trays and themselves upon entering the food collection area. This involves associating the user's identity information with a unique identifier on the tray to assign a tray to each user. Currently, most binding devices on the market require users to manually pick up their trays and place them at a designated location on the binding device, then scan both the user's identification medium (such as a dynamic QR code on a smartphone screen, NFC-enabled phone, RFID employee card, biometric identification, etc.) and the identifier on the tray (such as a QR code, barcode, RFID chip ID, etc.) before binding in the background. This operation mode is cumbersome and provides a poor user experience. During peak hours, it can easily cause queues and congestion at the entrance, affecting traffic efficiency. If the tray is placed too far from the scanning device, efficiency will be further reduced. In addition, since different users need to touch the trays on the public tray rack and place them on the public scanning platform, the risk of contact transmission of bacteria or viruses is increased. This is the main problem that needs to be solved. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a plate binding device for unit member canteens, so as to solve the problems of cumbersome steps, low efficiency, poor user experience and high hygiene risk of current conventional binding devices.

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A tray binding device for a unit member canteen; it includes a stand; an operating table is provided at the top of the stand; a human-machine interface screen for recognizing user information is provided at the top of the operating table; it also includes a tray feeder for transporting trays to the stand position; the tail end of the tray feeder extends into the middle of the stand and is positioned opposite the bottom end face of the operating table; an identifier for detecting individual markings on the trays is installed on the bottom side of the operating table.

[0006] Preferably, a cantilevered discharge plate is provided on the front side of the upright; the installation height of the discharge plate does not exceed the height of the tail end of the plate feeder, and the discharge plate is arranged adjacent to the tail end of the plate feeder.

[0007] Furthermore, the discharge plate is a zigzag plate structure, with its higher side connected to the upright and its lower side extending horizontally outward; a reinforcing rod is also provided between the discharge plate and the upright; baffles are provided on the left and right sides of the discharge plate to restrict the movement of the plates along the width direction of the discharge plate.

[0008] Preferably, the human-machine interface screen is installed at an angle of 10 to 20 degrees on the operating table; one or more of the following are integrated on the human-machine interface screen: a face recognition camera, a QR code recognition camera, or an RFID reader.

[0009] Preferably, the tray feeder is a tray conveyor mechanism; a sensor is also installed on the stand to detect whether a tray is placed at the tail end of the tray feeder; the sensor is connected to a control terminal that can control the operation of the tray feeder via a wire; the identifier and the human-machine interface screen are both connected to the control terminal via signal.

[0010] Preferably, the identifier includes one or more of the following: a QR code recognition camera or an RFID reader, and a QR code sticker or RFID chip that can be recognized by the QR code recognition camera or RFID reader is correspondingly set on the plate.

[0011] The beneficial effects of this utility model are reflected in the following aspects:

[0012] 1. Full-process automation improves efficiency and user experience;

[0013] Users only need to complete identity authentication (face scan / card swipe / code scan) through the human-computer interaction screen, and the plate feeder will automatically deliver the plate to the recognition position, saving users the steps of manually taking and placing the plate, effectively shortening the binding process from the traditional method and greatly reducing queuing congestion during peak hours.

[0014] 2. Zero-contact operation reduces hygiene risks;

[0015] Users do not need to touch the public food trays and scanning platform at all. The food trays are transported directly to the identification station under the relatively enclosed operating table via conveyor belt, blocking the contact transmission path and meeting the needs of upgraded catering hygiene.

[0016] 3. Precise positioning ensures a high success rate for recognition;

[0017] The end of the plate feeder is precisely aligned with the position of the reader, and the sensor monitors the plate's position in real time to ensure that the plate marking is always in the reader's optimal scanning area, avoiding recognition failures caused by human placement errors.

[0018] 4. Ergonomically optimized for convenient and stable operation;

[0019] The tilted human-machine interface screen allows users to operate directly; the cantilevered discharge plate with side baffles supports the trays delivered by the conveyor belt and guides users to easily pick them up, preventing slippage or deviation.

[0020] 5. Highly compatible and widely applicable;

[0021] It supports multimodal identity authentication such as face recognition, RFID card, and mobile phone QR code. The reader can be flexibly equipped with a QR code camera or RFID reading module to adapt to different plate marking schemes and meet the renovation needs of various unit canteens.

[0022] 6. The structure is robust and reliable, with low maintenance costs and a low failure rate, thereby reducing operating costs. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0027] Example:

[0028] Reference Figure 1 This embodiment provides a tray binding device for a unit member canteen; it includes a stand 1; an operating table 2 is provided on the top of the stand 1; a human-machine interface screen 3 for recognizing user information is provided on the top of the operating table 2; it also includes a tray feeder 4 for transporting trays to the stand position; the tail end of the tray feeder 4 extends into the middle of the stand and is positioned opposite to the bottom end face of the operating table 2; an identifier 5 for detecting independent markings on the trays is installed on the bottom side of the operating table 2.

[0029] A cantilevered discharge plate 9 is provided on the front side of the upright frame 1; the installation height of the discharge plate 9 does not exceed the height of the tail end of the plate feeder 4, and the discharge plate 9 is arranged adjacent to the tail end of the plate feeder 4.

[0030] The discharge plate 9 is a zigzag plate structure, with its higher side connected to the upright frame 1 and its lower side extending horizontally outward. A reinforcing rod 6 is also provided between the discharge plate 9 and the upright frame 1. Baffles are provided on the left and right sides of the discharge plate 9 to limit the movement of the plates along the width of the discharge plate 9. A buffer layer is provided on the inner wall of the baffle to prevent the plates from being damaged by collision. Anti-slip texture is provided on the surface of the discharge plate.

[0031] The human-machine interface screen 3 is mounted at an angle of 10-20° on the operating table 2. The screen integrates one or more of the following: a face recognition camera, a QR code recognition camera, or an RFID reader. In this embodiment, the screen is an Android-based tablet computer. The screen integrates face recognition, QR code recognition, and RFID reader modules, enabling rapid identification of the user. After successful authentication, a dynamic prompt icon guides the user to wait for their plate, which is then fed out from the dispensing plate by a plate feeder.

[0032] The tray feeder 4 is a tray conveyor mechanism. A sensor 8 is also installed on the support frame 1 to detect whether a tray is placed at the tail end of the tray feeder 4. The sensor 8 is connected to a control terminal 7 that controls the operation of the tray feeder 4 via a wire. The identifier 5 and the human-machine interface screen 3 are both connected to the control terminal 7. In this embodiment, the control terminal is a background computer based on the Windows system. The sensor 8 is an infrared sensor, positioned on the support frame at the same height as the tray on the tray feeder. When the infrared sensor detects that a tray is in place, it sends a signal to the control terminal. At this time, the identifier 5 can identify the information of the tray. After the user completes the verification on the human-machine interface screen, the tray can be bound to the user. The tray feeder is an LS500T type tray conveyor with a conveyor belt structure manufactured by Shanghai Shensui Automation Equipment Co., Ltd.

[0033] The identifier 5 includes one or more devices, such as a QR code recognition camera or an RFID reader. A QR code sticker or RFID chip, capable of being recognized by the camera or reader, is correspondingly placed on the plate. In this embodiment, a supplementary light is also provided at the identifier 5. The plate adopts the plate structure disclosed in the patent titled "A Novel Tray" (application number 2021231338895), with a QR code sticker and RFID chip placed in the center. The RFID reading unit of the identifier and the QR code camera are arranged side-by-side, and the control terminal can automatically switch to activate the corresponding recognition mode.

[0034] The following steps can be referred to when using the utility model device in this embodiment;

[0035] The tray feeder 4 pre-stores a tray queue, with the first tray stopping at the limit stop at the end of the conveyor belt. Sensor 8 continuously monitors the tray's position. The user completes facial recognition, card swiping, or QR code scanning via the human-machine interface screen 3, and the control terminal 7 verifies the validity of the user's permissions. Simultaneously with the human-machine interaction, the control terminal 7 starts the tray feeder 4 to deliver the tray to the identification station directly below the operating table 2. The limit stop mechanism at the end of the conveyor belt and sensor 8 work together to lock the tray's position, ensuring that the marked area aligns with the identifier 5. The identifier 5 immediately scans the QR code or RFID chip after the tray arrives, and the data is uploaded to the control terminal 7 in real time. After the user's identity is confirmed, the control terminal 7 associates the user ID with the tray ID and uploads it to the backend system. The human-machine interface screen 3 displays that the binding is successful. The user directly takes the tray from the horizontal section of the discharge plate 9, and the action of taking the tray triggers the sensor 8 to deactivate. The conveyor belt automatically replenishes the next tray to the standby position, and the equipment returns to its initial state to await the next operation.
