Description

Technical Field

[0001] This application relates to the technical field of conveying equipment, and in particular to an RGV track-type automatic guidance device. Background Technology

[0002] In the field of automated production and logistics, with the expansion of production scale and the continuous improvement of efficiency requirements, the demand for efficient and precise diversion and transportation of materials between different conveyor lines is growing. Traditional diversion and transportation methods often have many limitations. For example, some equipment has a complex structure and a large footprint, making it difficult to adapt to compact production layouts; or it is insufficient in terms of positioning accuracy and automation, which can easily lead to errors in the docking of multiple output conveyor lines, affecting the continuity of the entire production and transportation process.

[0003] In terms of drive and positioning control, traditional equipment typically uses relatively expensive devices such as laser displacement sensors to achieve the positioning and deceleration control of the trolley, which undoubtedly increases the manufacturing cost and subsequent maintenance cost of the equipment. At the same time, the roller drive method of some equipment is relatively simple and cannot be flexibly adjusted according to actual production needs, which also limits the applicability and versatility of the equipment under different working conditions to a certain extent.

[0004] Furthermore, the production environment is complex and changeable, and material conveying is easily affected by external factors, posing challenges to both equipment stability and adaptability to materials. For example, some equipment is prone to chain sagging and pallet misalignment under heavy loads, which in turn affects the accuracy and efficiency of material transfer.

[0005] RGV (Automated Guided Vehicle) is a promising piece of equipment in automated conveying systems, offering new ideas and solutions for addressing the aforementioned traditional diversion transportation problems. It demonstrates unique advantages in improving the flexibility and accuracy of material handling while reducing equipment costs, making it significant for enhancing the automation level and operational efficiency of the entire production logistics system. Utility Model Content

[0006] The purpose of this application is to provide an RGV track-type automatic guidance device to improve the automation level and operational efficiency of the entire production logistics system.

[0007] This application provides an RGV track-type automatic guiding device for realizing pallet diversion and transportation. The RGV track-type automatic guiding device includes an RGV track and an RGV vehicle body. The RGV track is set between the feeding device and at least two discharging devices. A limit structure is provided on the RGV track. The RGV vehicle body moves on the RGV track to transfer the raw materials input by the feeding device and carried by the pallet to any of the discharging devices.

[0008] The RGV vehicle body consists of a frame, a control system installed inside the frame, a transmission structure installed on the top of the frame, and a sensing structure installed on the side wall of the frame. The control system is used to drive the RGV vehicle body to move along the RGV track in a first direction. The transmission structure is used to transmit raw materials in a second direction, which is perpendicular to the first direction. The sensing structure is used to realize the positioning of the RGV vehicle body.

[0009] Furthermore, the conveying structure consists of multiple sets of rollers, and the roller surfaces are provided with anti-slip textures to enhance the friction between the rollers and the pallet.

[0010] Furthermore, the control system includes a geared motor, which drives a chain to control the rotation of multiple sets of rollers.

[0011] Furthermore, the control system includes three asynchronous motors and a main shaft. The two ends of the main shaft are connected to the two side walls of the frame respectively. The three asynchronous motors drive the main shaft to rotate, the main shaft drives the rollers to rotate, and further drives the follower wheels to rotate, so that the RGV body moves along the first direction. The three asynchronous motors control the RGV body to stop moving through motor brakes.

[0012] Furthermore, the sensing structure includes four sensors, which are installed at the four corners of the frame to receive the output signals from the signal transmitter on the discharge equipment, thereby enabling the deceleration and positioning of the RGV vehicle.

[0013] Furthermore, the RGV track includes a first ground rail and a second ground rail extending along a first direction. The first ground rail and the second ground rail are spaced apart along a second direction. Both ends of the first ground rail and both ends of the second ground rail are provided with track limiting structures to limit the movement distance of the RGV vehicle body on the first ground rail and the second ground rail.

[0014] Furthermore, the RGV track further includes multiple adjustment mounting plates, fixed plates, and pressure plates. The adjustment mounting plates and fixed plates are set at the bottom of the first ground rail or the second ground rail. One end of the pressure plate is fixed to the side wall of the first ground rail or the second ground rail, and the other end of the pressure plate is fixed to the side of the fixed plate away from the adjustment mounting plates. The adjustment mounting plates and fixed plates can be adjusted and fixed by mounting rods.

[0015] Furthermore, a limiting structure is provided at the bottom of the frame, with the limiting structure located at the four corners of the bottom of the frame, to prevent the moving structure of the frame from disengaging from the first ground rail or the second ground rail.

[0016] Furthermore, the RGV track further includes a drag chain guide groove disposed between the first ground rail and the second ground rail, and a drag chain mounting plate is disposed on the outer wall of the side plate of the frame. The drag chain mounting plate is used to install and fix the drag chain. The RGV body moves along the first ground rail and the second ground rail, and the drag chain moves in a restricted manner within the drag chain guide groove.

[0017] Furthermore, the RGV track-type automatic guidance device further includes a travel limit plate, which is disposed between the first ground rail and the second ground rail and is located away from the drag chain guide groove. A travel switch fixing plate is disposed on the outer wall of another frame side plate. The travel switch is fixedly disposed on the frame side plate through the travel switch fixing plate. The travel switch is used in conjunction with the travel limit plate to determine the travel start point of the RGV vehicle body.

[0018] Unlike existing technologies, the RGV track-type automatic guidance device of this application is installed between the feeding and discharging equipment and can connect to two or more discharging equipment. This enables flexible distribution of pallets between different conveyor lines, accurately allocating pallets from the feeding conveyor line to multiple discharging conveyor lines according to production processes and logistics needs. This significantly improves the flexibility and diversity of material handling, meeting the personalized material requirements of different workstations on complex production lines. It avoids problems such as material congestion or insufficient supply caused by traditional single conveying paths, optimizing the overall production logistics distribution efficiency and making the production process smoother and more efficient. This helps improve overall production efficiency and reduce production waiting time costs. Simultaneously, the RGV body is equipped with a corresponding control system, transmission structure, and sensing structure, enabling precise deceleration and positioning of the RGV body, improving the automation level and operational efficiency of the entire production logistics system.

[0033] like Figure 1 As shown, the RGV track-type automatic guide device 1 of this application is used to realize pallet diversion transportation. The RGV track-type automatic guide device 1 includes an RGV track 10 and an RGV vehicle body 20. The RGV track 10 is disposed between the feeding device and at least two discharging devices. A limit structure 211 is provided on the RGV track 10. The RGV vehicle body 20 moves on the RGV track 10 to transfer the raw materials input by the feeding device and carried by the pallet to any of the discharging devices.

[0034] The RGV vehicle body 20 consists of a frame 21, a control system 22 disposed within the frame 21, a transmission structure 23 disposed on the top of the frame 21, and a sensing structure 24 disposed on the side wall of the frame 21. The control system 22 drives the RGV vehicle body 20 to move along the RGV track 10 in a first direction. The transmission structure 23 is used to transmit raw materials in a second direction, which is perpendicular to the first direction. The sensing structure 24 is used to position the RGV vehicle body 20. Optionally, in this embodiment, the weight of the raw materials carried by the pallet can be about 1.5 tons. The RGV track-type automatic guiding device 1 can realize the rapid transfer and diversion of heavy materials, greatly improving the flexibility and diversity of material transportation.

[0035] The feeding device and the discharging device are located on both sides of the RGV track 10, and the feeding device and the discharging device have the same transmission direction, that is, the transmission direction is the second direction. The number of discharging devices can be set according to actual needs.

[0036] Furthermore, the RGV track 10 includes a first ground rail 11 and a second ground rail 12 extending along a first direction. The first ground rail 11 and the second ground rail 12 are spaced apart along a second direction. Track limiting structures 13 are provided at both ends of the first ground rail 11 and both ends of the second ground rail 12 to limit the movement distance of the RGV vehicle body 20 on the first ground rail 11 and the second ground rail 12.

[0037] Furthermore, the RGV track 10 further includes multiple adjusting mounting plates 14, fixing plates 15, and pressure plates 16. The adjusting mounting plates 14 and fixing plates 15 are disposed at the bottom of the first ground rail 11 or the second ground rail 12. One end of the pressure plate 16 is fixed to the side wall of the first ground rail 11 or the second ground rail 12, and the other end of the pressure plate 16 is fixed to the side of the fixing plate 15 away from the adjusting mounting plates 14. The adjusting mounting plates 14 and fixing plates 15 can be adjusted and fixed by mounting rods.

[0038] Furthermore, a limiting structure 211 is provided at the bottom of the frame 21. The limiting structure 211 is located at the four corners of the bottom of the frame 21 to prevent the frame 21 from swinging back and forth and to restrict the movement of the frame 21 from disengaging from the first ground rail 11 or the second ground rail 12.

[0039] Furthermore, the RGV track 10 further includes a drag chain guide groove 17 disposed between the first ground rail 11 and the second ground rail 12. A drag chain mounting plate (not shown) is disposed on the outer wall of the side plate of the frame 21. The drag chain mounting plate is used to install and fix the drag chain. The RGV body 20 moves along the first ground rail 11 and the second ground rail 12, and the drag chain moves in a restricted manner within the drag chain guide groove 17.

[0040] Furthermore, the RGV track-type automatic guidance device 1 further includes a travel limit plate 25, which is disposed between the first ground rail 11 and the second ground rail 12 and is located away from the drag chain guide groove 17. A travel switch fixing plate 212 is provided on the outer wall of the side plate of the other frame 21. The travel switch 213 is fixedly disposed on the side plate of the frame 21 through the travel switch fixing plate 212. The travel switch 213 is used in conjunction with the travel limit plate 25 to determine the travel start point of the RGV body 20.

[0041] Furthermore, the control system 22 includes a geared motor 221, which drives a chain to control the rotation of multiple sets of rollers 231.

[0042] Furthermore, the control system 22 includes a three-phase asynchronous motor 222 and a main shaft 223. The two ends of the main shaft 223 are respectively connected to the two side walls of the frame 21. The three-phase asynchronous motor drives the main shaft 223 to rotate, and the main shaft 223 drives the roller to rotate, which in turn drives the follower wheel to rotate, so that the RGV body 20 moves along the first direction. The three-phase asynchronous motor 222 controls the RGV body 20 to stop moving through the motor brake.

[0043] The main shaft 223 can be a two-section structure, with the two sections of rotating shaft connected by a rotating bearing, which then transmits the rotation.

[0044] Furthermore, the conveying structure 23 consists of multiple sets of rollers 231, the surface of which is provided with anti-slip texture to enhance the friction between the rollers 231 and the pallet. This embodiment, by enhancing the friction between the rollers 231 and the pallet, can prevent the pallet from slipping during conveying, ensuring the stability of material transport.

[0045] Furthermore, the sensing structure 24 includes four sensors 241, which are installed at the four apex corners of the frame 21 to receive the output signals from the signal transmitter on the discharge equipment, thereby achieving deceleration and positioning of the RGV body 20.

[0046] In this embodiment, the sensor 241 is a lower-cost sensor / sensor that replaces the traditional laser displacement sensor, which can reduce equipment costs. The sensor 241 is installed at the four top corners of the frame 21. According to the driving direction and position of the frame 21, the four sensors 241 sense the corresponding equipment lines to realize the deceleration and positioning of the RGV body 20.

[0047] Optionally, the sensing structure 24 in this embodiment may also include a position sensor for sensing the conveying of materials, specifically sensing the transmission from the feeding device to the RGV body 20 and from the RGV body 20 to the discharging device.

[0048] The RGV track-type automatic guide device 1 of this application is installed between the feeding equipment and the discharging equipment, and can be connected to two or more discharging equipment. It realizes the flexible diversion of pallets between different conveyor lines. According to the production process and logistics needs, it can accurately allocate pallets on the feeding conveyor line to multiple discharging conveyor lines, which greatly improves the flexibility and diversity of material transportation, meets the personalized material needs of different workstations on complex production lines, avoids the problems of material congestion or insufficient supply caused by traditional single conveying paths, optimizes the distribution efficiency of the entire production logistics, makes the production process smoother and more efficient, and helps to improve overall production efficiency and reduce production waiting time costs.

[0049] Furthermore, the RGV body 20 is equipped with a corresponding control system 22, transmission structure 23, and sensing structure 24, enabling precise deceleration and positioning of the RGV body 20, thereby improving the automation level and operational efficiency of the entire production logistics system. At the same time, using a lower-cost sensor 241 instead of a conventional laser displacement sensor further reduces equipment costs.

[0050] Therefore, the RGV track-type automatic guidance device 1 of this application exhibits unique advantages in improving the flexibility and accuracy of material conveying and reducing equipment costs, and is of great significance for improving the automation level and operating efficiency of the entire production logistics system.
