Description

Technical Field

[0001] This application relates to the field of AGV (Automated Guided Vehicle) technology, and more specifically, to a material storage parking unit. Background Technology

[0002] AGVs (Automated Guided Vehicles or Mobile Logistics Vehicles) are widely used in warehousing and logistics as automated transportation equipment. AGVs typically consist of a lurking robot and a material cart carried by the robot. After the lurking robot moves the material cart to its designated parking space, a lifting mechanism inside the parking space lifts the cart, separating it from the lurking robot. This allows the cart's wheels to leave the ground and the lurking robot to move smoothly out of the parking space. To ensure the cart can be smoothly driven in and out of the parking space by the lurking robot, guide rails are usually installed on the cart, and guide wheels are installed at the parking space. The guide rails and guide wheels work together to guide the cart's movement. However, when the lifting mechanism lifts the cart into the parking space, the guide rails and guide wheels often separate and derail, making it difficult for them to guide the cart when it leaves the parking space. Utility Model Content

[0003] The purpose of this application is to provide a material storage parking unit in response to at least one of the technical problems mentioned in the background art.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] This application provides a material storage parking unit, including a material cart and two parking components. The two parking components are symmetrically arranged in a first direction. The material cart includes a car body and an even number of roller guide components mounted on the car body. In the first direction, each roller guide component is symmetrically distributed on both sides of the car body. Each parking component includes a guide plate whose length direction is parallel to a second direction. The guide plate is arranged perpendicular to the horizontal plane, and the top edge of the guide plate is located above the roller guide components. The first direction and the second direction are perpendicular to each other and both are parallel to the horizontal plane. A material storage parking area is formed between the two guide plates. The roller guide components are used to roll in cooperation with the guide plates when the material cart moves relative to the parking component in the second direction.

[0006] Optionally, the guide plate includes a plate body portion and a guide plate portion arranged in the second direction. The guide plate portion is inclined relative to the second direction. The guide plate portion includes a connecting end fixed to the plate body portion and a free end disposed away from the plate body portion. The guide plate portion extends from the connecting end to the free end in a direction away from the material storage parking area.

[0007] The beneficial effect of this technical solution is that the guide plate parts of the two guide plates together form a structure similar to a horn. When the lurking robot carries the material cart to the material storage area, if the moving direction of the material cart does not accurately point to the material storage area, the roller guide component on the material cart will first contact the guide plate part and move between the two plate parts under the guidance of the guide plate part, and then gradually move to the material storage area. By setting the guide plate part, the material cart can be moved to the material storage area more accurately.

[0008] Optionally, the material cart includes four wheels and four roller guide assemblies, with each wheel evenly distributed on the bottom of the cart body and each roller guide assembly positioned close to each wheel in a corresponding manner.

[0009] The beneficial effect of this technical solution is that it makes the roller guide components more evenly distributed on both sides of the vehicle body, so that when the material car is in the material car parking area, the guide plates on both sides can evenly and evenly limit the two sides of the material car, making it less likely for the material car to shake when entering and leaving the material car parking area.

[0010] Optionally, the roller guide assembly includes two guide wheels.

[0011] The beneficial effects of this technical solution are that both guide wheels can be used to contact the guide plate, thereby improving the stability and reliability of guiding and limiting the material cart through the roller guide assembly and the storage position assembly.

[0012] Optionally, the two guide wheels in the roller guide assembly are arranged in the second direction, and the guide wheel located closer to the front of the vehicle in the first direction is closer to the inner side of the vehicle body.

[0013] The beneficial effect of this technical solution is that the common tangent of the outer sides of the two guide wheels in the roller guide assembly is inclined relative to the second direction, which is equivalent to the common tangent formed on both sides of the vehicle body forming an arrow-shaped structure, making it easier for the roller guide assembly on both sides of the vehicle body to enter between the two guide plates, and further improving the accuracy of guiding the material car into the material car parking area.

[0014] Optionally, the roller guide assembly is located below the vehicle body, and the vehicle body and the guide wheel partially overlap in the vertical direction.

[0015] The beneficial effect of this technical solution is that, under the premise that the guide wheels can partially extend out of the vehicle body to roll and cooperate with the guide plate, the degree of increase in the overall width of the material cart caused by adding guide wheels is reduced, thereby reducing the adverse effects on the flexible movement of the material cart carried by the lurking robot.

[0016] Optionally, the roller guide assembly further includes a roller mounting base, which includes a vertically arranged connecting plate and a horizontally arranged mounting plate. The connecting plate is fixedly connected to the mounting plate, and the top end of the connecting plate is detachably fixed to the vehicle body. The guide wheel is mounted on the mounting plate.

[0017] The beneficial effects of this technical solution are as follows: compared with directly mounting the guide wheels to the vehicle body, indirectly connecting the vehicle body and the guide wheels through the roller mounting base allows for targeted replacement of roller guide components with appropriate structures according to the material storage location structure, thereby improving the adaptability of the material vehicle.

[0018] Optionally, the connecting plate is detachably connected to the mounting plate.

[0019] The advantage of this technical solution is that it facilitates the replacement and repair of damaged guide wheels or mounting plates.

[0020] Optionally, the storage unit also includes a plurality of lifting cylinders mounted on the ground, each of the lifting cylinders being disposed between the two roller guide assemblies in the first direction.

[0021] The beneficial effect of this technical solution is that the roller guide components on both sides of the vehicle body are located outside each lifting cylinder, which avoids the lifting cylinders from obstructing the material car's entry and exit from the parking space.

[0022] Optionally, the lifting cylinders in the same storage unit are arranged in the second direction.

[0023] The technical solution provided in this application can achieve at least one of the following beneficial effects:

[0024] The material storage unit provided in this application, when in use, uses a stealth robot to carry a material cart in and out of the storage space in a second direction. During the process of entering and exiting the storage space, the roller guide components located on both sides of the cart body roll in cooperation with the corresponding guide plates to guide the movement direction of the material cart. Since the guide plates are larger in the vertical direction than the guide rails used in the prior art, and the top edge of the guide plate is located above the roller guide components, the roller guide components can move a larger range in the vertical direction without separating from the guide plates. This makes it less likely for the roller guide components to separate from the guide plates when the material cart moves in the vertical direction under the drive of the lifting component, thus achieving the purpose of obtaining high-precision guidance and positioning when the material cart enters and exits the storage space.

[0025] The additional technical features and advantages of this application will become more apparent from the following description or from practical application. Attached Figure Description

[0041] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] like Figures 1 to 6 As shown, this application provides a material storage unit, including a material cart 01 and two storage components 02. The two storage components 02 are symmetrically arranged in a first direction. The material cart 01 includes a cart body 03 and an even number of roller guide components 04 installed on the cart body 03. In the first direction, each roller guide component 04 is symmetrically distributed on both sides of the cart body 03. The storage component 02 includes a guide plate 11 whose length direction is parallel to a second direction. The guide plate 11 is arranged perpendicular to the horizontal plane. The top edge of the guide plate 11 is located above the roller guide components 04. The first direction and the second direction are perpendicular to each other and both the first direction and the second direction are parallel to the horizontal plane. A material storage area is formed between the two guide plates 11. The roller guide components 04 are used to roll with the guide plate 11 when the material cart 01 moves relative to the storage component 02 in the second direction.

[0045] Understandably, the direction in which the lurking robot carries material cart 01 into and out of the storage location of material cart 01 is parallel to the second direction.

[0046] The material storage unit provided in this application, during use, involves a stealth robot 100 carrying a material cart 01 to and from the storage location in a second direction. During this process, roller guide assemblies 04 located on both sides of the cart body 03 engage with corresponding guide plates 11 to guide the movement of the material cart 01. Because the guide plates 11 are larger in the vertical direction than the guide rails used in existing technologies, and their top edges are positioned above the roller guide assemblies 04, the roller guide assemblies 04 can move a greater range vertically without separating from the guide plates 11. This makes it less likely for the roller guide assemblies 04 to separate from the guide plates 11 when the material cart 01 moves vertically under the influence of the lifting mechanism, achieving high-precision guidance and positioning for both the material cart 01 entering and exiting the storage location. Figure 6 As shown, optionally, the guide plate 11 includes a plate body portion 12 and a guide plate portion 13 arranged in the second direction. The guide plate portion 13 is inclined relative to the second direction. The guide plate portion 13 includes a connecting end fixed to the plate body portion 12 and a free end disposed away from the plate body portion 12. The guide plate portion 13 extends from the connecting end to the free end in a direction away from the material storage parking area. That is, the guide plate portions 13 of the two guide plates 11 together form a structure similar to a trumpet. When the lurking robot 100 carries the material cart 01 to the material storage parking area, if the moving direction of the material cart 01 is not accurately pointing to the material storage parking area, the roller guide assembly 04 on the material cart 01 will first contact the guide plate portion 13 and move between the two plate body portions 12 under the guidance of the guide plate portion 13, and then gradually move to the material storage parking area. By setting the guide plate portion 13, the material cart 01 can move to the material storage parking area more accurately. In this embodiment, the guide plate portion 13 can be replaced by a guide rail fixedly connected to the guide plate 11.

[0047] like Figures 2 to 4 As shown, optionally, the material cart 01 includes four wheels 09 and four roller guide assemblies 04. Each wheel 09 is evenly distributed at the bottom of the vehicle body 03, and each roller guide assembly 04 is correspondingly positioned close to each wheel 09. This ensures that the roller guide assemblies 04 are evenly distributed on both sides of the vehicle body 03, allowing the guide plates 11 on both sides of the material cart 01 to provide even and balanced positioning when the material cart 01 is in the material storage parking area, preventing the material cart 01 from shaking when entering or exiting the parking area.

[0048] Optionally, the roller guide assembly 04 includes two guide wheels 06. Both guide wheels 06 can be used to contact the guide plate 11, thereby improving the stability and reliability of guiding and limiting the material cart 01 through the roller guide assembly 04 and the storage position assembly 02.

[0049] Optionally, the two guide wheels 06 in the roller guide assembly 04 are arranged in the second direction, and the guide wheel 06 located closer to the front of the vehicle in the first direction is closer to the inner side of the vehicle body 03. In this way, the common tangent line of the outer sides of the two guide wheels 06 in the roller guide assembly 04 is inclined relative to the second direction, which is equivalent to the common tangent lines formed on both sides of the vehicle body 03 forming an arrow-like structure. This makes it easier for the roller guide assemblies 04 on both sides of the vehicle body 03 to enter between the two guide plates 11, further improving the accuracy of guiding the material car 01 into the material storage parking area. Of course, the two guide wheels 06 in the roller guide assembly 04 are equidistant from the centerline of the vehicle body 03.

[0050] Optionally, the roller guide assembly 04 is located below the vehicle body 03, with the vehicle body 03 partially overlapping the guide wheel 06 in the vertical direction. This allows the guide wheel 06 to partially extend outward from the vehicle body 03 to roll in cooperation with the guide plate 11, reducing the overall increase in width of the material cart 01 caused by adding the guide wheel 06, thereby minimizing the adverse effects on the flexible movement of the material cart 01 carried by the stealth robot 100. Of course, the roller guide assembly 04 can also be installed entirely on the side of the vehicle body 03.

[0051] Optionally, the roller guide assembly 04 further includes a roller mounting base 05. The roller mounting base 05 includes a vertically arranged connecting plate 07 and a horizontally arranged mounting plate 08. The connecting plate 07 is fixedly connected to the mounting plate 08, and the top end of the connecting plate 07 is detachably fixed to the vehicle body 03. The guide wheel 06 is mounted on the mounting plate 08. Compared to directly mounting the guide wheel 06 to the vehicle body 03, indirectly connecting the vehicle body 03 and the guide wheel 06 through the roller mounting base 05 allows for targeted replacement of the roller guide assembly 04 with a corresponding structure according to the storage location structure of the material cart 01, thereby improving the adaptability of the material cart 01.

[0052] Optionally, the connecting plate 07 and the mounting plate 08 are detachably connected. This facilitates the replacement and repair of damaged guide wheels 06 or mounting plates 08. In this embodiment, both the connecting plate 07 and the mounting plate 08 are preferably T-shaped plates.

[0053] like Figure 5 As shown, optionally, the storage unit 02 also includes a plurality of lifting cylinders 10 installed on the ground, each of the lifting cylinders 10 being positioned between two of the roller guide assemblies 04 in the first direction. That is, the roller guide assemblies 04 on both sides of the vehicle body 03 are located outside each lifting cylinder 10, thus avoiding obstruction of the material cart 01 from entering and exiting the storage area by each lifting cylinder 10.

[0054] Optionally, the lifting cylinders 10 in the same storage unit 02 are arranged in the second direction. In this embodiment, preferably, the storage unit 02 includes 2 to 4 lifting cylinders 10.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
