Description

Technical Field

[0001] This utility model applies to the field of material handling and provides a positioning mechanism for rail-guided handling equipment. Background Technology

[0002] Rail-guided material handling equipment refers to material handling devices that run on tracks, typically used for transporting goods in factories, warehouses, ports, and other similar locations. Its main function is to automate the transport of materials and products by moving along predetermined tracks, thereby improving production efficiency and reducing manual handling costs.

[0003] Rail-guided transport equipment typically consists of a vehicle body, tracks, a drive unit, a transmission system, and a positioning device. The vehicle body is the main body of the equipment, the drive unit provides power through a motor or other power source, and the tracks serve as the path for the equipment's movement. To ensure the equipment moves accurately along the tracks, a positioning and fixing system is usually required. This system generally includes sensors, encoders, and positioning modules, used to monitor the equipment's position in real time and make corrections and adjustments as needed, thereby ensuring the equipment runs smoothly along the predetermined path.

[0004] However, current positioning mechanisms for rail-guided transport equipment still have many shortcomings in practical applications. First, traditional positioning methods often rely on ground markings or coded tracks, which are susceptible to problems such as marking wear and environmental changes, resulting in low positioning accuracy. Second, existing positioning mechanisms are generally unable to adapt to complex environmental changes, such as slight track curvature or positional shifts, which affects the equipment's operational stability and positioning accuracy. Furthermore, existing positioning systems often rely on a single positioning method, lacking sufficient redundancy and intelligent design, making the equipment prone to malfunctions or positioning errors when encountering abnormal conditions. Utility Model Content

[0005] To address the aforementioned deficiencies, the present invention aims to provide a positioning mechanism for a rail-guided transport device, thereby solving the problems mentioned in the background art. The device includes a cabinet and a track installed beside the cabinet. The cabinet has a multi-layered platform structure for carrying goods, and each layer of the platform structure is equipped with a cabinet label frame. The track is equipped with a bottom plate label frame corresponding to the position of the cabinet. A lifting railcar for transporting goods is installed on the track, and the lifting railcar is equipped with a lifting plate for lifting and lowering, and clamping equipment for loading and unloading goods is installed on the lifting plate.

[0006] The bottom of the lifting railcar and the side of the lifting plate are respectively equipped with a first detector and a second detector, which are used to detect the identification labels on the cabinet label frame and the bottom plate label frame, respectively.

[0007] Furthermore, the cabinet includes four uprights for support, and support beams are provided on adjacent uprights. The support beams and uprights together form a multi-layer frame structure. Each layer is fixedly connected to a support plate for carrying goods. A front panel is fixedly connected to the side of the support plate near the track. The cabinet label frame is installed on the front panel.

[0008] Furthermore, it also includes a base plate located at the bottom, to which both the cabinet and the rails are fixedly connected.

[0009] Furthermore, a cabinet label frame is fixedly connected to the front panel, which is used to attach or clip identification labels; a bottom plate label frame is provided on the bottom plate at the corresponding position of the track.

[0010] Furthermore, both the cabinet label frame and the bottom plate label frame are equipped with identification tags containing the current location information of the shelf.

[0011] Furthermore, both the first and second detectors are barcode scanning devices, and the identification label is a barcode.

[0012] Furthermore, a first signal transmitter is fixedly connected to the front panel, and a second signal transmitter is fixedly connected to the bottom plate.

[0013] Furthermore, both the first and second signal transmitters are infrared signal transmitters.

[0014] This invention not only significantly improves the operating efficiency and positioning accuracy of the rail-guided handling and sorting system, but also reduces the long-term operating costs of the system due to its simple structure and convenient maintenance, providing strong technical support for modern intelligent warehousing and logistics.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0023] Example 1

[0024] See Figure 1-3 The purpose of this utility model is to provide a positioning mechanism for a rail-guided handling device, including a cabinet 1 and a track 3 installed beside the cabinet 1; specifically, both the cabinet 1 and the track 3 are fixedly connected to the bottom plate 01. The cabinet 1 includes four uprights 11 for support, and adjacent uprights 11 are provided with support beams. The support beams and uprights together form a multi-layer frame structure, and each layer is fixedly connected with a support plate 12 for carrying goods. A front panel 13 is fixedly connected to the side of the support plate 12 closest to the track.

[0025] A cabinet label frame 14 is fixedly connected to the front panel 13, and the cabinet label frame 14 is used to affix or clamp identification labels. Simultaneously, a base plate label frame 31 is provided on the base plate 01 at the corresponding position on the track 3. The base plate label frame 31 corresponds to each loading position of the cabinet 1. A lifting railcar 2 for transporting goods is provided on the track 3. The lifting railcar 2 is equipped with a lifting plate 21 for lifting, and a clamping device 22 for loading and unloading goods is installed on the lifting plate 21. In one embodiment, the clamping device 22 can use a robotic arm to clamp the goods. The function of the lifting railcar 2 is to run on the track 2; specifically, it can be driven by a motor to travel on the track 2 (since the railcar traveling on the track and the robotic arm clamping the goods are existing technologies, they will not be described in detail here).

[0026] The bottom of the lifting railcar 2 and the side of the lifting plate 21 are respectively equipped with a first detector 231 and a second detector 232, which are used to detect the identification labels on the cabinet label frame 14 and the bottom plate label frame 31, respectively.

[0027] Therefore, this utility model is applicable to rail-guided handling and sorting systems, where the handling and sorting equipment moves on rail-guided racks, and the handling and sorting equipment is attached to... Figure 1 The lifting railcar 2, the cabinet label frame 14 and the bottom plate label frame 31 are identified by graphic labels that contain the current position information of the shelf; the first detector 231 and the second detector 232 can identify the graphic labels when passing by the identification labels, thereby controlling the operation and start / stop of the equipment.

[0028] Specifically, the lifting railcar 2 communicates with an external terminal in real time. After detecting the identification tag, the first detector 231 and the second detector 232 can send signals to the terminal. The terminal analyzes the tag and sends a positioning signal, and controls the start and stop of the handling and sorting equipment based on the positioning signal and the current position information.

[0029] In other words, the first detector 231 can accurately determine the position information of the handling and sorting equipment on the track and whether it is in place; the second detector 232 can accurately determine whether the lifting position of the lifting plate 21 is in place.

[0030] Optionally, the first detector 231 and the second detector 232 can be barcode scanning devices to identify the label as a barcode. In this case, the process of using the device is to scan the barcode to obtain the graphic identifier. At this time, the barcode scanning device obtains real-time image data of the barcode area and can know the location of the barcode and information such as the goods kept on the shelf.

[0031] Example 2

[0032] Based on Embodiment 1, the difference from Embodiment 1 is that a first signal transmitter 15 is fixedly connected to the front panel 13, and a second signal transmitter 32 is fixedly connected to the bottom plate 01; the first signal transmitter 15 and the second signal transmitter 32 can be infrared signal transmitters.

[0033] The second signal transmitter 32 corresponds to each loading position of the vertical cabinet 1. A lifting railcar 2 for transporting goods is installed on the rail 3. The lifting railcar 2 is equipped with a lifting plate 21 that can be used for lifting. The lifting plate 21 is equipped with clamping equipment 22 for loading and unloading goods.

[0034] The bottom of the lifting railcar 2 and the side of the lifting plate 21 are respectively equipped with a first detector 231 and a second detector 232, which are used to receive infrared signals emitted by the first signal transmitter 15 and the second signal transmitter 32. The first signal transmitter 15 and the second signal transmitter 32 can emit infrared light of different frequencies. After receiving the signals, the first detector 231 and the second detector 232 can determine the location of their own equipment and thus accurately reach the target location.

[0035] In Embodiment 1 above, the first detector 231 and the second detector 232 are barcode scanning devices capable of recognizing barcode labels. It is understood that the scanning device captures and decodes the barcode image to obtain the corresponding information. Suitable devices include fixed industrial-grade QR code readers, such as Cognex's DataMan370 series. After successful scanning, the external terminal receives the location information sent by the reader and compares it with the target location. When a match is successful, the terminal immediately sends deceleration or stop commands to the trolley drive motor and lifting motor, thereby achieving precise positioning.

[0036] In Embodiment 2 above, the infrared transmitter can use a high-power infrared emitting diode such as the Vishay TSAL6100; the infrared receiver can use a photoelectric sensor from the Sick WL4-3P323 or Omron E3S-X3 series; the infrared receiver and the infrared emitting diode together form a switching signal; after the switching signal is detected, it is directly sent to the control system. The external terminal does not need to decode complex data; detecting the signal immediately triggers a stop or halting of the lifting action. This makes the system simpler and more reliable.

[0037] In summary, during actual use, the lifting railcar 2 runs along the track 3 under the drive of a motor. When it needs to stop at a specific loading layer of the vertical container 1, the first detector 231 at the bottom of the car body continuously detects and scans the bottom plate label frame 31 at the bottom of the track (or receives a specific frequency infrared signal emitted by the second signal transmitter 32). Once an identification tag or signal matching the target position is identified, the first detector 231 transmits the information to the external terminal in real time. The terminal then controls the lifting railcar 2 to decelerate and stop precisely, completing the initial horizontal positioning. Immediately afterwards, the lifting plate 21 begins to drive the clamping device 22 to move vertically. During this process, the second detector 232 installed on the side of the lifting plate 21 simultaneously scans the vertical container label frame 14 located on the front panel 13 (or receives an infrared signal emitted by the first signal transmitter 15). When an identification tag or signal corresponding to the target loading position is detected, feedback is sent to the terminal that the lifting plate 21 has accurately reached its position. Ultimately, the terminal integrates the positioning signals from both horizontal and vertical dimensions and sends instructions to the clamping equipment 22, which then performs precise cargo grabbing or storage operations, thereby achieving fully automated control of the entire process from operation and alignment to loading and unloading.

[0038] Therefore, the device can form an efficient and reliable two-dimensional positioning network through the horizontal positioning system consisting of the first detector 231 and the base plate label frame 31 (or the second signal transmitter 32), and the vertical positioning subsystem consisting of the second detector 232 and the cabinet label frame 14 (or the first signal transmitter 15). This greatly improves the positioning accuracy and reliability of the lifting railcar 2 and the lifting plate 21, and effectively avoids the risk of misalignment or collision caused by single-point detection failure.

[0039] Meanwhile, the device is compatible with both graphic identification and infrared signal detection methods, giving the system greater environmental adaptability and configuration flexibility, and enabling the selection of the most suitable solution according to different scenario requirements.

[0040] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
