[0078] Optionally, the docking sensor 19 is disposed on the mounting frame 17 .

[0079] like Figure 5 As shown, according to an embodiment of the utility model, an automatic guided transport vehicle 2 is also proposed, comprising: a roller conveyor line 20; and a blocking device 1 as proposed in any of the above items, wherein along the transmission direction of the roller conveyor line 20, the blocking device 1 is located at least one of the two ends of the roller conveyor line 20.

[0080] The automatic guided transport vehicle 2 provided by the utility model comprises the blocking device 1 proposed in any of the above embodiments, and therefore has all the beneficial effects of the blocking device 1.

[0081] In a specific application, along the transmission direction of the roller conveyor line 20, the blocking device 1 is arranged at both ends of the roller conveyor line 20, so that the materials can be blocked at both ends of the roller conveyor line 20 to prevent the materials from falling during the movement.

[0082] It is understandable that the automatic guided transport vehicle 2 also includes a driving device, which is used to drive the rollers 24 of the roller conveyor line 20 to rotate, thereby realizing the loading and unloading of materials.

[0083] like Figure 5 As shown, according to some embodiments of the present application, optionally, the automatic guided transport vehicle 2 also includes: a main body 22, a roller conveyor line 20 and a blocking device 1 are arranged on the main body 22, the roller conveyor line 20 is arranged in at least two rows, any row of roller conveyor lines 20 includes a plurality of rollers 24 arranged along the transmission direction, and at least two rows of roller conveyor lines 20 are distributed along the rotation axis of the rollers 24; at least one of the two ends of any row of roller conveyor lines 20 along the transmission direction is correspondingly provided with a blocking device 1.

[0084] In this embodiment, the automatic guided transport vehicle 2 also includes a body 22, a roller conveyor line 20 and a blocking device 1 are arranged on the body 22, and the body 22 can move, thereby driving the movement of the material on the roller conveyor line 20 to realize the automatic guided transport function. Among them, the roller conveyor line 20 is arranged in at least two rows, which increases the material conveying volume and improves the conveying efficiency, while also reducing the vertical occupation of the space. Any row of roller conveyor lines 20 includes a plurality of rollers 24, and the movement of the material is realized when the rollers 24 rotate, thereby realizing automatic loading and unloading. At least two rows of roller conveyor lines 20 are distributed along the rotation axis of the rollers 24, and a blocking device 1 is provided at least at one end of the conveying direction of any row of roller conveyor lines 20. The blocking device 1 can block the material at at least at one end of any roller conveyor line 20 to prevent the material from falling from either end of the conveying direction during the movement of the automatic guided transport vehicle 2.

[0085] Optionally, blocking devices 1 are provided at both ends of any row of roller conveyor lines 20 along the transmission direction.

[0086] like Figure 5 As shown, according to some embodiments of the present application, optionally, along the rotation axis direction of the roller 24 , the blocking device 1 is arranged corresponding to the middle part of the roller 24 .

[0087] In this embodiment, the blocking device 1 is arranged at the middle of the roller 24 along the rotation axis of the roller 24 , thereby improving the blocking effect on the material and reducing the space occupied by the roller conveyor line 20 .

[0088] like Figure 5 and Figure 7 As shown, according to some embodiments of the present application, optionally, the automatic guided transport vehicle 2 also includes: the main body 22 is provided with a through hole 220, and the docking sensor 19 of the blocking device 1 is arranged corresponding to the through hole 220; the automatic guided transport vehicle 2 also includes: a control device 26, which is connected to the docking sensor 19 and the driving unit 11, and is used to control the operation of the driving unit 11 according to the docking sensor 19; when the docking sensor 19 detects that the docking is completed and the material is loaded, after the loading is completed, the control device 26 controls the baffle 12 to extend out of the working surface of the roller conveyor line 20 through the driving unit 11; when the docking sensor 19 detects that the docking is completed and the material is unloaded, before the material is unloaded, the control device 26 controls the baffle 12 to retract to the bottom of the roller conveyor line 20 through the driving unit 11.

[0089] In this embodiment, the docking sensor 19 is arranged corresponding to the through hole 220 on the main body 22, and the docking with the docking body is achieved through the through hole 220. The automatic guided transport vehicle 2 also includes a control device 26, which is connected to the docking sensor 19 and the drive unit 11, and then controls the baffle 12 to extend or retract after the docking sensor 19 detects that the docking between the automatic guided transport vehicle 2 and the docking body is completed. Among them, the drive unit 11 is connected to the control device 26. After the loading is completed, the control device 26 controls the drive unit 11 to operate so that the baffle 12 extends out of the working surface of the roller conveyor line 20 to block the material on the roller conveyor line 20 and prevent the material from falling. In the case of unloading, the control device 26 controls the movement of the drive unit 11 so that the baffle 12 retracts to the bottom of the roller conveyor line 20, thereby avoiding affecting the unloading process.

[0090] Optionally, the control device 26 is also connected to the driving device of the roller conveyor line 20, and can control the automatic guided transport vehicle 2 to stop after the docking sensor 19 detects that the automatic guided transport vehicle 2 is aligned with the docking body, and then control the roller conveyor line 20 to load and unload materials.

[0091] In a specific application, the present application proposes a blocking mechanism (e.g., blocking device 1) for a roller AGV, which rises from the bottom to the top and is used in scenarios where the left and right dimensions are restricted. Blocking mechanisms are added to both the front and rear ends of the roller conveyor line 20; the blocking mechanism is linked to the conveyor line through the docking sensor 19 and has a logical relationship; the blocking mechanism has its own detection limit sensor (e.g., position detection member 13) to prevent exceeding the limit.

[0092] The present application provides a blocking mechanism for a roller 24-type AGV for loading and unloading materials on both sides to solve the risk of materials slipping out of the roller conveyor line 20 in the above-mentioned background technology. The risk of material damage and delay in automated production during operation is greatly reduced, and fully automatic safe transportation and handling are realized, thereby improving efficiency.

[0093] To achieve the above-mentioned purpose, the present application provides the following solution: a blocking mechanism for a double-sided loading and unloading roller 24-type AGV, comprising an AGV body 22, which includes a docking sensor 19; a roller conveyor line 20, which includes a position detection reflective sensor; and a blocking module, which includes an extreme limit sensor (such as a position detection component 13).

[0094] Specifically, all components are installed on the base plate (such as the mounting plate 10), and the main blocking plate (such as the baffle 12) is installed on the guide rail 18, and the guide rail 18 is used to slide up and down, and the guide rail 18 is installed on the mounting frame 17. The blocking plate slides up and down, and the action is realized by the electric push rod 112. The blocking plate and the electric push rod 112 are fixedly connected by a connecting member (such as the third connecting plate 16) and a connecting screw. The electric push rod 112 is fixed to the base plate. The proximity sensor (such as the position detection member 13) that detects whether it is in place is fixedly connected to the base plate through a connecting member (the first connecting plate 14) and a connecting member (such as the second connecting plate 15).

[0095] When the third connecting plate 16 is fixed to the electric push rod 112, the connection part of the third connecting plate 16 is a waist-shaped hole, so that when the blocking plate is hit, it will deform and displace, and will not generate radial force on the electric push rod 112 to cause damage to it.

[0096] The proximity sensor is fixedly connected to the first connecting plate 14 and the second connecting plate 15. The connecting parts of the first connecting plate 14 and the second connecting plate 15 are waist-shaped holes, so that the front and back, up and down positions of the proximity sensor can be adjusted. Real-time adjustment can be performed during installation and debugging to prevent the proximity sensor from failing to sense the position.

[0097] By adopting the above scheme, the specific implementation method is as follows:

[0098] In normal state, the blocking plate is located below the roller conveyor line 20 and does not interfere with the upper and lower materials. The roller 24 type AGV navigates to the docking point, docks with the conveyor line through the docking sensor 19, and sends information to dock the materials.

[0099] Furthermore, the blocking plate is usually in the lowest state. When the roller 24-type AGV and the conveyor line (such as the docking body) are aligned, the docking sensor 19 sends information and prepares to carry out the loading process.

[0100] Further, the material loading process is carried out, and the roller 24 of the AGV starts to run. It stops running when the material is directly above the AGV. Then the blocking mechanism starts to work. The electric push rod 112 drives the blocking plate to run through the slider, and stops running after the proximity sensor (such as the first sensor 130) above detects a signal. At this time, the blocking plate is already in the extended mode, and the material will not slide off the roller 24 line due to acceleration, deceleration, turning, etc.

[0101] The unloading process is similar. The roller 24-type AGV carries the material and transports it to the unloading point. The docking sensor 19 is aligned with the sensor of the conveyor line and then stops. At this time, the blocking plate is in the extended state. Then the unloading process is carried out. The electric push rod 112 drives the blocking plate, which runs through the slider and stops running after the proximity sensor below (such as the second sensor 132) detects a signal. At this time, the blocking plate is already in the retracted mode.

[0102] The double-sided loading and unloading roller AGV has added a blocking mechanism to prevent the material from slipping out of the roller conveyor line 20 during loading and unloading and driving, thus solving this risk once and for all. The blocking mechanism works completely automatically and is controlled by the sensor's detection working logic to achieve fully automatic seamless connection and improve production efficiency. The in-place detection mode of the blocking mechanism may be replaced with other types of sensors, or other methods may be used to detect whether the lifting is in place. The up and down movement of the blocking plate may be driven by other methods, such as a lead screw.

[0103] The blocking mechanism proposed in this application prevents the phenomenon of materials sliding out of the double-sided loading and unloading roller AGV; it relies on circuit sensor control logic to automatically determine take-off and landing, thereby achieving fully automatic operation.
