Description

Technical Field

[0001] This invention relates to the field of cargo transfer vehicle technology, and in particular to a cargo transfer vehicle based on an intelligent warehousing system and its usage method. Background Technology

[0002] In material warehousing, transfer vehicles are often needed to quickly transfer materials. Existing warehouse transfer vehicles usually consist of a walking mechanism and a transfer platform. They are simple in structure, convenient and practical, and easy to transfer goods. With the development of intelligent technology, by installing robotic arms on the vehicle's moving platform and equipping them with a recognition system, goods can be automatically gripped and placed on the transfer vehicle, effectively improving work efficiency and saving the labor intensity of workers.

[0003] When transferring goods, transfer vehicles generally need to move and transport the picked-up and placed goods to another workshop warehouse. When driving outdoors in the factory area, the goods in the storage box of the transfer vehicle are generally not covered due to the influence of the weather, and are wetted by rain and snow, causing damage to the goods. To address this problem, we propose a goods transfer vehicle based on an intelligent warehousing system and its usage method. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that goods in the storage boxes of existing transfer vehicles generally lack covering and are damaged by rain and snow. The invention proposes a cargo transfer vehicle based on an intelligent warehousing system and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cargo transfer vehicle based on an intelligent warehousing system includes a vehicle body, a placement box mounted on the top of the vehicle body, a mounting base fixed to one side of the placement box on the top of the vehicle body, a retrieval component fixedly mounted on the mounting base, a movable protective cloth positioned above the placement box, airbags disposed on the inner wall surface of the placement box, and a rotating cylinder mounted on the top surface of the protective cloth, the rotating cylinder being in contact with the surface of the protective cloth. When the protective cloth moves to the left, it covers and protects the bottom of the placement box, while simultaneously inflating the airbags to elastically limit the cargo filled in the placement box. When the protective cloth moves to the right, it drives the rotating cylinder to rotate synchronously, tensioning and limiting the protective cloth.

[0007] Preferably, a movable plate is fixedly connected to one end of the protective cloth, and slides are installed at both ends of the movable plate. The slides are slidably connected to a slide rail, which is fixedly installed on the top surface of the placement box. A fixed plate is fixedly connected to the bottom surface of the movable plate.

[0008] Preferably, a drive unit is fixedly connected to one side of the fixed plate, a first side plate is fixedly connected to one end of the drive unit, the first side plate is fixedly installed on the top surface of the vehicle body, an inclined plate is fixedly connected to one side of the first side plate, and the drive unit is embedded in the inclined plate.

[0009] Preferably, one end of the protective cloth is provided with a storage tube, and a spiral spring is provided inside the storage tube. One end of the spiral spring is fixedly connected to the protective cloth, and the protective cloth slides through the storage tube. One end of the storage tube is fixedly connected to a second side plate, and the bottom of the second side plate is fixedly connected to the vehicle body.

[0010] Preferably, a first connecting cylinder is fixedly connected to one side of the fixed plate on the drive unit, a first piston is slidably connected inside the first connecting cylinder, a first sliding rod is fixedly connected to one side of the first piston, the end of the first sliding rod is fixedly connected to the first side plate, and a first air chamber is formed inside the first sliding rod and the first piston.

[0011] Preferably, one end of the first slide rod is fixedly connected to an air supply pipe, and the end of the air supply pipe passes through the first side plate and the placement box and is connected to the airbag.

[0012] Preferably, a second connecting cylinder is fixedly connected to one side of the fixed plate on the other side of the drive unit, and an air inlet is fixedly connected to one end of the second connecting cylinder, with a one-way valve provided on the air inlet.

[0013] Preferably, a second piston is slidably connected inside the second connecting cylinder, a second slide rod is fixedly connected to one side of the second piston, the end of the second slide rod is fixedly connected to the first side plate, a valve is provided inside the second piston, a second air chamber is opened inside the second piston and the second air chamber, and a conveying pipe is fixedly connected to one end of the second slide rod.

[0014] Preferably, the end of the conveying pipe passes through the first side plate and is fitted with a hollow shaft via a rotary joint. The hollow shaft is rotatably connected to the second side plate via a bearing, and the end of the hollow shaft is fixedly connected to the rotating cylinder.

[0015] A method for using a cargo transfer vehicle based on an intelligent warehousing system mainly includes the following steps:

[0016] Step A: Move the vehicle body to the cargo placement area in advance. When picking up the cargo, the robotic arm automatically picks up the cargo in the placement area and places it inside the placement box to realize automated loading and unloading of cargo. The protective cloth set on the placement box will move the protective cloth through the drive component after the cargo is placed inside the placement box to cover the top of the placement box.

[0017] Step B: When the protective cloth covers the top of the placement box, it drives the air to be compressed and delivered to the airbag, causing the airbag to inflate. When the protective cloth is removed from the placement box, some of the collected gas is delivered to the rotating cylinder, and the gas is sprayed out through the rotating cylinder, thereby cleaning and accelerating the flow of water stains remaining on the top surface of the protective cloth.

[0018] Compared with the prior art, the present invention provides a cargo transfer vehicle based on an intelligent warehousing system, which has the following beneficial effects:

[0019] 1. This cargo transfer vehicle based on an intelligent warehousing system uses a protective cloth installed on the placement box. When goods are placed inside the placement box, the protective cloth is moved by a drive component to cover the top of the placement box, thereby protecting the placed goods and preventing damage to the transfer vehicle from rain and snow during handling and transportation, thus improving the quality of cargo transfer and transportation.

[0020] 2. This cargo transfer vehicle based on an intelligent warehousing system, when the protective cloth covers the top of the placement box, drives air compression and delivers it to the airbag, causing the airbag to inflate, thereby protecting the goods placed in the placement box and preventing the vehicle from colliding with the inner wall of the placement box during the journey, which would cause damage to the goods.

[0021] 3. This cargo transfer vehicle based on an intelligent warehousing system, when the protective cloth is removed from the placement box, transports some of the collected gas to the rotating drum, and sprays the gas through the rotating drum to clean and guide the water stains remaining on the top surface of the protective cloth, making it easier to store and organize.

[0022] The parts of this device not described herein are the same as or can be implemented using existing technologies. This invention, through the protective cloth, can cover and protect the bottom of the placement box, thus sealing the goods inside the placement box and providing excellent protection. This prevents the goods from being affected by rain and snow during outdoor transportation. At the same time, when covered, the airbag can inflate and provide elastic protection to the inner walls of the placement box, preventing the goods from shaking and colliding during transportation, reducing the occurrence of damage during transportation, and making it convenient and quick to use.

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "multiple" means two or more.

[0034] In the description of this specification, the terms "one embodiment," "some implementations," "specific embodiment," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0035] Reference Figures 1-8 A cargo transfer vehicle based on an intelligent warehousing system includes a vehicle body 1, a placement box 2 mounted on the top of the vehicle body 1, a mounting base 3 fixed on one side of the placement box 2 on the top of the vehicle body 1, a retrieval component 31 fixedly mounted on the mounting base 3, a movable protective cloth 4 positioned above the placement box 2, an airbag 66 positioned on the inner wall surface of the placement box 2, and a rotating cylinder 79 mounted on the top surface of the protective cloth 4, with the rotating cylinder 79 in contact with the surface of the protective cloth 4. When the protective cloth 4 moves to the left, it covers and protects the bottom of the placement box 2, while simultaneously inflating the airbag 66 to elastically limit the cargo filled in the placement box 2. When the protective cloth 4 moves to the right, it drives the rotating cylinder 79 to rotate synchronously, thus tensioning and limiting the protective cloth 4.

[0036] In use, the vehicle body 1 is pre-moved to the cargo placement area. The retrieval component 31 includes a robotic arm and a robotic hand, and is equipped with a scanning control system. When retrieving goods, the robotic hand automatically picks up the goods from the placement area and places them inside the placement box 2, achieving automated loading and unloading. This is existing technology and will not be elaborated further. Considering that the storage area for goods in existing warehouse transfer vehicles is not covered, and the transfer of goods between warehouses within the factory area requires traversing outdoor areas, some special goods are easily affected by rain, snow, or sun exposure during outdoor transport, causing damage. Therefore, in designing this solution, a protective cloth 4 is installed on the placement box 2. After the goods are placed inside the placement box 2, the protective cloth 4 is moved by a drive mechanism, allowing the goods to be placed inside the placement box 2. It covers the top of the placement box 2 to protect the placed goods and prevent damage from rain and snow during transportation, thus improving the quality of goods transportation. When the protective cloth 4 covers the top of the placement box 2, it compresses the air and delivers it to the airbag 66, causing the airbag 66 to inflate and protect the goods placed in the placement box 2, preventing the vehicle from colliding with the inner wall of the placement box 2 during driving and causing damage to the goods. When the protective cloth 4 is removed from the placement box 2, some of the collected gas is delivered to the rotating cylinder 79, and the gas is sprayed out through the rotating cylinder 79 to clean the water stains remaining on the top surface of the protective cloth 4 and accelerate the drainage, making it easier to store and organize. At the same time, the rotating cylinder 79 can limit the protective cloth 4 in the covered state, making the protective cloth 4 more flat when covered.

[0037] In a preferred embodiment, refer to Figure 3 , Figure 4 and Figure 8 One end of the protective cloth 4 is fixedly connected to a movable plate 41. Both ends of the movable plate 41 are equipped with slide seats 42. The slide seats 42 are slidably connected to the slide rail 44. The slide rail 44 is fixedly installed on the top surface of the placement box 2. The bottom surface of the movable plate 41 is fixedly connected to a fixed plate 43. One side of the fixed plate 43 is fixedly connected to a drive unit 441. One end of the drive unit 441 is fixedly connected to a first side plate 45. The first side plate 45 is fixedly installed on the top surface of the vehicle body 1. One side of the first side plate 45 is fixedly connected to a slope plate 46. The drive unit 441 is embedded in the slope plate 46.

[0038] The drive unit 441 uses an electric push rod or other drive source instead of a drive. When in use, by starting the drive unit 441, the moving plate 41 can be moved, thereby causing the protective cloth 4 to be moved out from the inside of the storage tube 51 and then cover the top surface of the placement box 2 to cover and protect the goods inside the placement box 2. When the vehicle is driving in the environment outside the warehouse, it can effectively avoid the impact of rain, snow or sun exposure on the goods.

[0039] The slide block 42 slides on the surface of the slide rail 44, which can limit the movement of the slide rail 44 and improve the stability of the protective cloth 4 when it moves. Together with the rotating cylinder 79, the protective cloth 4 is horizontally attached to the top of the placement box 2 when it is covered.

[0040] In a preferred embodiment, refer to Figure 6 One end of the protective cloth 4 is provided with a storage tube 51. Inside the storage tube 51 is a spiral spring 52. One end of the spiral spring 52 is fixedly connected to the protective cloth 4. The protective cloth 4 slides through the storage tube 51. One end of the storage tube 51 is fixedly connected to a second side plate 53. The bottom of the second side plate 53 is fixedly connected to the vehicle body 1.

[0041] The storage tube 51 is convenient for storing the protective cloth 4. When the protective cloth 4 does not need to be covered, the protective cloth 4 is retracted into the storage tube 51 by the elastic pull of the spiral spring 52 inside the storage tube 51. It is convenient and quick to use and does not affect the subsequent loading and unloading of goods on the transfer vehicle.

[0042] In a preferred embodiment, refer to Figure 4 and Figure 6 The surface of the fixed plate 43 is fixedly connected to one side of the drive unit 441 with a first connecting cylinder 61. The first piston 62 is slidably connected inside the first connecting cylinder 61. A first slide rod 63 is fixedly connected to one side of the first piston 62. The end of the first slide rod 63 is fixedly connected to the first side plate 45. A first air chamber 64 is opened inside the first slide rod 63 and the first piston 62. An air supply pipe 65 is fixedly connected to one end of the first slide rod 63. The end of the air supply pipe 65 passes through the first side plate 45 and the placement box 2 and communicates with the airbag 66.

[0043] The first slide bar 63 and the first piston 62 are equipped with a first air chamber 64, which is connected to the inside of the first connecting cylinder 61. When the protective cloth 4 moves to the left, the first piston 62 squeezes the air inside the first connecting cylinder 61. The air passes through the first slide bar 63 and is then transported to the inside of the airbag 66, causing the airbag 66 to inflate. When the airbag 66 inflates, the surface in contact with the goods is raised in a grid pattern with equal spacing, which better fits the goods stacked inside and provides a good cushioning and protection effect, preventing the goods from colliding and shaking during transportation. At the same time, when the protective cloth 4 is removed, the gas inside the airbag 66 flows back, creating a gap between the goods in the box 2 and the side surface of the airbag 66, making it easier for the robot arm to pick up the goods later.

[0044] In a preferred embodiment, refer to Figure 2 , Figure 4 and Figure 5A second connecting cylinder 71 is fixedly connected to one side of the fixed plate 43 on the other side of the drive unit 441. An air inlet 72 is fixedly connected to one end of the second connecting cylinder 71. A one-way valve is provided on the air inlet 72. A second piston 73 is slidably connected inside the second connecting cylinder 71. A second slide rod 74 is fixedly connected to one side of the second piston 73. The end of the second slide rod 74 is fixedly connected to the first side plate 45. A valve 75 is provided inside the second piston 73. A second air chamber 76 is opened inside the second piston 73 and the second air chamber 76. A conveying pipe 77 is fixedly connected to one end of the second slide rod 74. A hollow shaft 78 is installed through the first side plate 45 via a rotary joint at the end of the conveying pipe 77. The hollow shaft 78 is rotatably connected to the second side plate 53 via a bearing. The end of the hollow shaft 78 is fixedly connected to the rotating cylinder 79.

[0045] When the protective cloth 4 moves to the right and is rolled up, the gas pre-collected in the second connecting cylinder 71 can be squeezed and transported to the rotating cylinder 79, and then sprayed out through multiple air jets 791 on the rotating cylinder 79, thereby cleaning the rainwater or snowflakes that fall on the top surface of the protective cloth 4 during rainy or snowy weather, making it easier to collect and organize the protective cloth 4. At the same time, the surface of the rotating cylinder 79 is in close contact with the top surface of the protective cloth 4, and the rotating cylinder 79 rotates synchronously when the protective cloth 4 is displaced, which limits the protective cloth 4 without affecting the stretching and contraction of the protective cloth 4. This makes the protective cloth 4 horizontal and flat in the covered state, and better fits the top of the placement box 2.

[0046] It should be noted that the air outlet of the jet nozzle 791 is located in the middle part of the protective cloth 4 and is set at an angle to both sides to prevent foreign objects from being blown into the interior of the placement box 2. The valve 75 is a one-way valve.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
