Description

Technical Field

[0001] This invention relates to the field of rail delivery technology, specifically to a rail delivery robot. Background Technology

[0002] Among the most common food delivery robots on the market today, most are designed to meet the needs of fun and entertainment, and their actual food delivery capabilities are far from meeting the requirements, especially the food delivery needs of high-traffic areas such as canteens, restaurants, and hotels.

[0003] Existing food delivery robots, such as the "intelligent food delivery robot" disclosed in patent authorization number CN103340514A, include a moving device, a lifting device, a food delivery device, and a recycling device. The food delivery device is installed on the moving device, and a recycling device is fixed to one side of the food delivery device. This food delivery robot can adjust the position of the tray, ensuring that it can adapt to the needs of tables of different heights, significantly improving its compatibility with tables of different sizes, and has a wide range of applications; that is, it completes food delivery needs through a single food cart-type robot.

[0004] In the aforementioned application, when food is delivered using a single food cart-type robot, the robot can only reach different dining locations, with each delivery following a different trajectory. This results in excessively long delivery times, making it inconvenient for high-traffic areas and prone to delays. Furthermore, it cannot accurately place the trays onto the customer's table. Therefore, we provide a track-based delivery robot. Summary of the Invention

[0005] The purpose of this invention is to provide a track delivery robot.

[0006] The technical problem solved by this invention is:

[0007] (1) When delivering food by a single food cart robot, the robot can only reach different dining locations for dining. The delivery location trajectory is different each time, and the delivery time is too long each time. It is inconvenient to deliver food to places with high traffic, which can easily lead to untimely delivery.

[0008] (2) At the same time, the current food delivery robots cannot accurately and reliably deliver the food trays to the customer's table.

[0009] The present invention can be achieved through the following technical solution: a track delivery robot, including an installation track, a guide rail on the installation track, a vehicle body slidably installed on the guide rail, a moving component on the vehicle body that drives it to move along the length direction of the guide rail, a fixed platform above the vehicle body, a linear lifting component on the vehicle body that drives the fixed platform to move up and down, a sliding plate slidably installed on the fixed platform, and a double-layer driving component on the fixed platform that drives the sliding plate to slide horizontally.

[0010] A further technical improvement of the present invention is that: the double-layer drive component includes a first moving mechanism and a second moving mechanism, a slide table is horizontally slidably connected to the fixed platform, a slide disk is horizontally slidably connected to the slide table, the first moving mechanism is installed on the fixed platform and drives the fixed platform to slide horizontally to both sides of the guide rail, and the second moving mechanism is installed on the slide disk and drives the slide disk to slide horizontally to both sides of the guide rail.

[0011] A further technical improvement of the present invention is that: the first moving mechanism includes two drive shafts and a drive rack, the drive rack is arranged on the slide table along the sliding direction of the slide table, the two drive shafts are rotatably connected to the fixed table, each drive shaft is provided with a drive gear that meshes with the drive rack, the fixed table is provided with a rotating motor, and the output shaft of the rotating motor is connected to one of the drive shafts, and the two drive shafts are connected by a synchronous pulley and a synchronous belt.

[0012] A further technical improvement of the present invention is that: the second moving mechanism includes a transmission motor, a transmission rack and a transmission gear. The transmission motor is mounted on the slide, the transmission gear is mounted on the output shaft of the transmission motor, the transmission rack is mounted on the slide, and the transmission rack is arranged along the sliding direction of the slide. The transmission gear meshes with the transmission rack for transmission. An auxiliary moving part is provided on the slide, and the auxiliary moving part is arranged opposite to the transmission motor.

[0013] A further technical improvement of the present invention is that: the auxiliary moving part includes a drive shaft, which is rotatably mounted on a slide. The slide is also provided with a drive gear that meshes with the drive rack. The drive shaft is connected to the output shaft of the drive motor through a drive wheel and a drive belt.

[0014] A further technical improvement of the present invention is that: a fixed block is provided on one side of the slide, a movable block is slidably installed on the side of the slide away from the fixed block, a fixed motor is provided on the side of the slide near the movable block, a fixed screw is rotatably connected to the slide, and the fixed screw is arranged along the line connecting the fixed block and the movable block. The fixed screw is connected to the output shaft of the fixed motor through gear transmission, and the movable block is provided with an end plate nut that is threadedly connected to the fixed screw.

[0015] A further technical improvement of the present invention is that a fixing groove is provided on the side of the moving block and the fixed block that are close to each other.

[0016] A further technical improvement of the present invention is that: the linear lifting component includes a cross telescopic bracket, the cross telescopic bracket is vertically mounted on the vehicle body, the telescopic end of the cross telescopic bracket is connected to a fixed platform, and the vehicle body is provided with an electric drive component for driving the cross telescopic bracket to extend and retract.

[0017] A further technical improvement of the present invention is that: the moving part includes two travel shafts, which are rotatably connected to the bottom of the vehicle body. Each travel shaft is provided with a number of travel wheels, and the travel wheels are located on a guide rail. The vehicle body is provided with a travel motor that drives the two travel shafts to rotate in the same direction.

[0018] A further technical improvement of the present invention is that guide wheels are provided on both sides of the vehicle body, and the guide wheels are located on both sides of the guide rail.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present invention drives two driving shafts and several driving wheels to rotate by a driving motor, thereby driving the entire vehicle body, its components and the plate to move along the guide rail, thereby moving the plate to the corresponding position on the installation track, which is convenient for people on both sides of the installation track to eat. The movement trajectory is the same each time, which makes it easy for the robot to locate the food delivery position, improving the food delivery efficiency and the robot's recycling efficiency.

[0021] (2) By rotating the motor, synchronous pulley and synchronous belt, the two drive shafts and drive gears are driven to rotate, so that the drive rack meshes with the drive gear and drives the slide to slide horizontally. Then, the drive motor drives the drive gear to rotate, thereby driving the slide and the plate on it to move horizontally along the length of the drive rack, so that the plate can smoothly leave the fixed table and reach above the person's dining position. Then, the electric drive component drives the cross telescopic bracket to extend and retract, driving the fixed table, slide and plate to move up and down, so that the plate can be accurately moved to the table at the corresponding height, realizing the precise delivery of the plate and improving the delivery effect.

[0022] (3) By driving the fixed screw to rotate through the output shaft of the fixed motor, the moving block and the end plate nut are moved closer or further away from the fixed block to fix the plate and improve the stability of the plate during transport, or to release the plate from the fixed position to facilitate the taking of the plate after the transport is completed.

[0023] (4) The guide wheels on both sides of the guide rail are used to lock the position of the two sides of the vehicle body, so that the vehicle body moves along the guide rail and guides the vehicle body; at the same time, the guide wheels on both sides of the guide rail prevent the two sides of the vehicle body from shaking, thereby improving the stability of the vehicle body and the plate during transportation and preventing the food on the plate from falling off.

[0032] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0033] Please see Figures 1-6 As shown, this invention proposes a track-based delivery robot, comprising an installation track 1, a guide rail 2 on the installation track 1, a vehicle body 3 slidably mounted on the guide rail 2, a moving component on the vehicle body 3 for driving it to move along the length of the guide rail 2, a fixed platform 4 above the vehicle body 3, a linear lifting component on the vehicle body 3 for driving the fixed platform 4 to move up and down, a sliding plate 5 slidably mounted on the fixed platform 4, and a double-layer driving component on the fixed platform 4 for driving the sliding plate 5 to slide horizontally; the dining positions for personnel are located on both sides of the installation track 1, and the trays are placed on the fixed platform 4. The system moves the vehicle body 3, its components, and the plate along the guide rail 2 via a moving component, allowing them to reach the designated dining position for the person. Then, a double-layer drive mechanism moves the fixed platform 4 and the plate horizontally, moving the plate to the person's dining position. A linear lifting mechanism then moves the fixed platform 4, the sliding plate 5, and the plate vertically, accurately placing the plate on the table at the appropriate height for precise delivery. After the plate delivery is complete, the vehicle body 3 can be moved and retracted via the guide rail 2, improving retrieval efficiency.

[0034] The double-layer drive unit includes a first moving mechanism 6 and a second moving mechanism 7. A slide table 8 is horizontally slidably connected to the fixed platform 4, and a slide disk 5 is horizontally slidably connected to the slide table 8. The first moving mechanism 6 is installed on the fixed platform 4 and drives the fixed platform 4 to slide horizontally to both sides of the guide rail 2. The second moving mechanism 7 is installed on the slide disk 5 and drives the slide disk 5 to slide horizontally to both sides of the guide rail 2.

[0035] The first moving mechanism 6 includes two drive shafts 601 and a drive rack 602. The drive rack 602 is mounted on the slide table 8 along the sliding direction of the slide table 8. The two drive shafts 601 are rotatably connected to the fixed platform 4. Each drive shaft 601 is equipped with a drive gear 603 that meshes with the drive rack 602. The fixed platform 4 is equipped with a rotary motor, and the output shaft of the rotary motor is connected to one of the drive shafts 601. The two drive shafts 601 are connected by a synchronous pulley 604 and a synchronous belt. The rotary motor, synchronous pulley 604, and synchronous belt drive the two drive shafts 601 to rotate, which in turn drives the drive gears 603 to rotate, causing the drive rack 602 to mesh with the drive gears 603, and thus the slide table 8 on the drive rack 602 slides horizontally.

[0036] The second moving mechanism 7 includes a drive motor 701, a drive rack 702, and a drive gear 703. The drive motor 701 is mounted on the slide plate 5, the drive gear 703 is mounted on the output shaft of the drive motor 701, and the drive rack 702 is mounted on the slide table 8, with the drive rack 702 arranged along the sliding direction of the slide plate 5. The drive gear 703 meshes with the drive rack 702 for transmission. An auxiliary moving component is provided on the slide plate 5, and the auxiliary moving component is arranged opposite to the drive motor 701. The drive motor 701 drives the drive gear 703 to rotate, thereby causing the slide plate 5 and the plate on it to move horizontally along the length direction of the drive rack 702, so that the plate can smoothly leave the fixed table 4 and reach the dining position of the person.

[0037] The auxiliary moving component includes a drive shaft 704, which is rotatably mounted on the slide 5. The slide 5 is also equipped with a drive gear 703 that meshes with the drive rack 702. The drive shaft 704 is connected to the output shaft of the drive motor 701 via a transmission wheel and a transmission belt. When the drive motor 701 drives the drive gear 703 to rotate, the transmission wheel and the transmission belt drive the drive shaft 704 and the drive gear 703 to rotate, thus assisting in the horizontal movement of the slide 5 and the plate on it along the length of the drive rack 702, improving the stability of the slide 5 during sliding.

[0038] A fixed block 9 is provided on one side of the slide plate 5, and a movable block 10 is slidably installed on the side of the slide plate 5 away from the fixed block 9. A fixed motor 11 is provided on the side of the slide plate 5 near the movable block 10. A fixed screw 13 is rotatably connected to the slide plate 5, and the fixed screw 13 is set along the line connecting the fixed block 9 and the movable block 10. The fixed screw 13 and the output shaft of the fixed motor 11 are connected by a fixed gear 12. An end plate nut 14 is provided on the movable block 10 and is threadedly connected to the fixed screw 13. The tray is placed between the fixed block 9 and the movable block 10. The fixed motor 11 drives the fixed screw 13 to rotate, which in turn moves the movable block 10 and the end plate nut 14 toward the fixed block 9, thus fixing the tray in place and improving the stability of the tray during transport. When the tray is transported to the corresponding position, the output shaft of the fixed motor 11 drives the fixed screw 13 to rotate, which in turn moves the movable block 10 and the end plate nut 14 away from the fixed block 9, thus releasing the tray from the fixed block 9 and allowing it to fall accurately onto the person's dining position.

[0039] Both the movable block 10 and the fixed block 9 have fixing grooves 15 on their adjacent sides. The fixing grooves 15 facilitate the fixing of both sides of the plate, improving the plate's fixing efficiency.

[0040] The linear lifting mechanism includes a cross-telescopic bracket 16, which is vertically mounted on the vehicle body 3. The telescopic end of the cross-telescopic bracket 16 is connected to the fixed platform 4. The vehicle body 3 is equipped with an electric drive unit that drives the cross-telescopic bracket 16 to extend and retract. The electric drive unit drives the cross-telescopic bracket 16 to extend and retract, thereby causing the fixed platform 4, the sliding plate 5, and the plate to move up and down, so that the plate can be accurately moved to the table at the corresponding height.

[0041] The moving component includes two travel axles 17, which are rotatably connected to the bottom of the vehicle body 3. Each travel axle 17 is equipped with several travel wheels 18, all of which are located on the guide rail 2. The vehicle body 3 is equipped with a travel motor that drives the two travel axles 17 to rotate in the same direction. The travel motor drives the two travel axles 17 and the several travel wheels 18 to rotate, thereby moving the entire vehicle body 3, its components, and the plate, thus moving the plate to the corresponding position on the mounting rail 1.

[0042] Guide wheels 19 are provided on both sides of the vehicle body 3, and the guide wheels 19 are located on both sides of the guide rail 2. The guide wheels 19 on both sides of the guide rail 2 lock the positions of the vehicle body 3, allowing the vehicle body 3 to move along the guide rail 2 and guide the vehicle body 3; at the same time, the guide wheels 19 on both sides of the guide rail 2 prevent the vehicle body 3 from swaying, thereby improving the stability of the vehicle body 3 and the tray during transportation and preventing the food on the tray from falling off.

[0043] In use, the plate is placed between the fixed block 9 and the movable block 10. The fixed motor 11 drives the fixed screw 13 to rotate, thereby moving the movable block 10 and the end plate nut 14 towards the fixed block 9, thus fixing the plate in place. The travel motor drives two travel shafts 17 and several travel wheels 18 to rotate, moving the entire vehicle body 3, its components, and the plate, thus moving the plate to the corresponding position on the mounting track 1. The rotating motor, synchronous pulley 604, and synchronous belt drive two drive shafts 601 and drive gear 603 to rotate, causing the drive rack 602 to mesh with the drive gear 603, and driving the slide table 8 to move... After horizontal sliding, the drive motor 701 drives the drive gear 703 to rotate, thereby causing the sliding plate 5 and the plate on it to move horizontally along the length of the drive rack 702, so that the plate can smoothly leave the fixed platform 4 and reach above the person's dining position. Then, the electric drive unit drives the cross telescopic bracket 16 to extend and retract, causing the fixed platform 4, sliding plate 5 and plate to move up and down, so that the plate can be accurately moved to the table at the corresponding height. The output shaft of the fixed motor 11 drives the fixed screw 13 to rotate, thereby causing the moving block 10 and the end plate nut 14 to move away from the fixed block 9, so as to release the plate and allow the plate to fall accurately to the person's dining position, completing the plate delivery process.
