[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there can be a central component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0033] The following specific embodiments are used to describe in detail the technical solution of the utility model and how the technical solution of the present application solves the above technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0034] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] Figure 1 Schematic diagram of the application scenario of the safety fence in the embodiment of the present application, such as Figure 1 As shown, the application scenario includes: a platform 10, a ground 20, a container 30, a loading and unloading robot 40, a telescopic roller line 50, and a safety fence 60. The container 30 (which can also be a transport vehicle, such as a truck, a train, etc.) is parked on the ground 20 adjacent to the platform 10, and the loading and unloading robot 40 operates on the platform to continuously transport the materials on the telescopic roller line 50 to the container 30 (the same applies to the unloading scenario, which will not be expanded here). Since there are people coming and going on the platform, it is easy for someone to accidentally break into the working space of the loading and unloading robot 40, thereby causing a safety accident. Therefore, a safety fence 60 is set to isolate the working area of ​​the loading and unloading robot 40.

[0036] Figure 2 This is a schematic diagram of an application scenario of the embodiment of the present application during loading and unloading operations, such as Figure 2 As shown, the safety fence 60 is U-shaped as a whole, with one open side docking with the container 30, one end of the loading and unloading robot 40 is connected to one side of the telescopic roller line 50, and the other side of the telescopic roller line 50 passes through the channel of the safety fence 60 and extends to the outside of the safety fence 60. It should be noted that Figure 2 The scene on the other side of the telescopic roller line 50 is not shown. Generally speaking, another robot can place the materials on the transport vehicle or pallet on the telescopic roller line 50, and then the telescopic roller line 50 transports them to the inside of the safety fence 60 to reach the operating range of the loading and unloading robot 40.

[0037] It should be noted that the present embodiment does not limit the type of the loading and unloading robot 40 , which may be a single-arm robot or a dual-arm robot.

[0038] For example, Figure 3 This is a schematic diagram of the layout of the safety fence in the embodiment of the present application. Figure 4 This is a top view of the safety fence used in the embodiment of the present application. Figure 3 , Figure 4 As shown, the loading and unloading robot 40 is a dual-arm robot, and the two mechanical arms can alternately grab or place materials from the telescopic roller line 50. Furthermore, the loading and unloading robot 40 can enter the container 30 to perform loading or unloading operations. At this time, one end of the telescopic roller line 50 connected thereto also extends to the container 30 along with the loading and unloading robot 40.

[0039] Figure 5 This is a three-dimensional view of the safety fence in the embodiment of the present application, such as Figure 5 As shown, it includes: a plurality of columns 61 and a fence 63, wherein the fence 63 is arranged between two adjacent columns 61, and a roller 65 is arranged at the lower end of each column 61, and the interior of the U-shaped fence separated by the columns 61 and the fence 63 constitutes a safe space for loading and unloading operations, wherein: one side of the opening of the U-shaped fence faces the edge of the platform docking side for docking transport vehicles, and the other side opposite to the opening of the U-shaped fence is provided with a passage for convenient loading and unloading of materials; one side of the loading and unloading robot is connected to one end of the transmission mechanism, and the other end of the transmission mechanism extends to the outside of the U-shaped fence through the passage.

[0040] It should be noted that the present embodiment does not limit the type of the transmission mechanism, and the transmission mechanism may be any transport mechanism with a telescopic function, such as a telescopic belt conveyor and / or a telescopic roller line.

[0041] Exemplarily, the passage is located between two columns 61, and the crossbeam 62 at the top of the passage and the fence at the bottom of the crossbeam 62 are detachable structures. When in a separated state, the U-shaped fence is split into two L-shaped structures.

[0042] For example, Figure 6 This is a front view of the safety fence in the embodiment of the present application, as shown in FIG. Figure 6 As shown, the seine located below the crossbeam 62 includes a first top seine 67 and a second top seine 68, and the first top seine 67 and the second top seine 68 are separable structures.

[0043] Figure 7 Schematic diagram of the structure after the safety fence is disassembled in the embodiment of the present application. Figure 7 As shown, in an optional embodiment, in the L-shaped structure, two adjacent fences at the turning point are connected to the pillars by hinges, so that the two adjacent fences can be freely adjusted between a folded state and an unfolded state.

[0044] In this embodiment, two adjacent fences are connected by hinges, which can facilitate the storage of the fences and reduce the space they occupy.

[0045] Figure 8 This is a side view of the safety fence in the embodiment of the present application, as shown in FIG. Figure 8 As shown, a safety gate 66 is also provided on at least one side of the U-shaped fence, and the fence at the safety gate 66 can be moved by a slide rail located at the top of two columns.

[0046] In an optional embodiment, it also includes: an application entry button, which is installed on a column corresponding to the safety door and is used to open and / or close the safety door.

[0047] Exemplarily, when the safety door 66 is opened, the loading and unloading robot located inside the U-shaped fence stops working.

[0048] For example, because the loading and unloading robot sometimes operates in the passage, in the actual environment, it is always possible to temporarily cross the working space of the loading and unloading vehicle. In order to ensure the safety of personnel, a "request entry button" is specially set to control the safety door 66. Assuming that a person forcibly breaks into the safety door, the loading and unloading robot is immediately forced to shut down, and the robot arm remains in the stopped state. During the loading and unloading operation, if an abnormality occurs, the safety door of the fence opens, and at the same time triggers the robot to enter the emergency stop state, so as to allow personnel to enter the working space to check and handle the equipment, materials, and environment.

[0049] Fig. 9 This is a partial enlarged view of the safety fence in the embodiment of the present application, such as Fig. 9 As shown, a brake 64 for braking a roller is also provided at the lower end of the column 61 .

[0050] In an optional embodiment, the power cord of the loading and unloading robot is routed from the bottom end of the transmission mechanism and is connected to the power supply outside the U-shaped fence after passing through an automatic reel.

[0051] In this embodiment, since the loading and unloading robot is always in an active state, its power cord will also be dragged along. If the power cord cannot be tidied, it is easy to be entangled by the active robotic arm or roller, causing an accident. Therefore, the power cord is arranged by an automatic reel to ensure operation safety.

[0052] In this embodiment, a safety fence composed of multiple columns and fences is provided. The fence is provided between two adjacent columns, and a roller is provided at the lower end of each column. The U-shaped fence separated by the columns and the fences constitutes a safe space for loading and unloading operations, wherein: one side of the opening of the U-shaped fence faces the side edge of the platform for docking with transport vehicles, and the other side opposite to the opening of the U-shaped fence is provided with a passage for loading and unloading materials; one side of the loading and unloading robot is connected to one end of the transmission mechanism, and the other end of the transmission mechanism extends to the outside of the U-shaped fence through the passage. In this way, the safety of the robot during loading and unloading operations can be ensured, and accidents caused by people accidentally entering the robot can be prevented. At the same time, the robot can be flexibly arranged according to the on-site environment. When the robot completes the loading and unloading operations, it can be quickly evacuated, which is convenient to use.

[0053] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the embodiments can be referred to each other. The above description of the disclosed embodiments enables professionals and technicians in this field to implement or use the utility model.
