[0002] At present, roller-type automated guided vehicles (AGVs) are widely used in factory production to improve transportation efficiency. However, during the process of transporting materials by an automated guided vehicle, the materials are prone to fall off the AGV, especially under conditions such as acceleration and deceleration, or turning, or when the material surface is smooth or columnar, the material is prone to move on the AGV and then fall off the end of the roller conveyor line of the AGV. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] To this end, a first aspect of the utility model provides a blocking device.

[0005] The second aspect of the utility model also provides an automatic guided transport vehicle.

[0006] In view of this, the first aspect of the utility model proposes a blocking device for an automatic guided transport vehicle, the automatic guided transport vehicle includes a roller conveyor line, and the blocking device is located at at least one of the two ends of the roller conveyor line along the transmission direction of the roller conveyor line, the blocking device includes: a base, located at the bottom of the roller conveyor line; a drive assembly, connected to the base, and located at the bottom of the roller conveyor line; a baffle, connected to the drive assembly, and the drive assembly is used to drive the baffle to rotate between a first position and a second position; when the baffle is in the first position, the baffle is located at the bottom of the roller conveyor line; when the baffle is in the second position, at least a portion of the baffle protrudes from the working surface of the roller conveyor line, and is used to block the material on the roller conveyor line.

[0007] The utility model provides a blocking device for an automatic guided transport vehicle, which includes a roller conveyor line. Along the transmission direction of the roller conveyor line, the blocking device is arranged at at least one of the two ends of the roller conveyor line to block the material at at least one of the two ends of the roller conveyor line. The blocking device includes a base, a drive assembly and a baffle. The base and the drive assembly are both arranged at the bottom of the roller conveyor line to avoid affecting the loading and unloading process of the roller conveyor line. The drive assembly is arranged on the base, and the baffle is connected to the drive assembly. The drive assembly can drive the baffle to rotate between a first position and a second position: when the baffle is at the first position, the baffle is at the bottom of the roller conveyor line to avoid affecting the loading and unloading process; when the baffle is at the second position, at least a part of the baffle protrudes from the working surface of the roller conveyor line, which is used to block the material on the roller conveyor line, so as to prevent the automatic guided transport vehicle from causing the material to fall from the roller conveyor line due to acceleration or turning. At the same time, the drive assembly is used to drive the baffle to rotate between the first position and the second position, so that when the blocking device is rotated back to the first position, it is located at the bottom of the roller conveyor line, with a small size, simple structure, and cost savings, thereby avoiding occupying the space of the automatic guided transport vehicle.

[0008] The blocking device provided by the utility model may also have the following additional technical features:

[0009] In some possible designs, the driving assembly includes: a driving member, which is arranged on the base; and a rotating shaft, one end of which is connected to the driving member and the other end of which is connected to the baffle.

[0010] In this design, the driving assembly includes a driving member and a rotating shaft. The driving member is arranged on a base. The rotating shaft is connected to the driving member and the baffle. The driving member drives the baffle to rotate between a first position and a second position via the rotating shaft, so that when the baffle is in the first position, the space occupied by the blocking device as a whole is reduced, and when the baffle is in the second position, the material is blocked.

[0011] In some possible designs, the blocking device further includes: a position detection component, corresponding to the baffle or the rotating shaft, and used to detect the position of the baffle.

[0012] In this design, the blocking device also includes a position detection component, which corresponds to the baffle or the rotating shaft. The rotating shaft and the baffle can rotate simultaneously under the action of the driving member. Therefore, when the position detection component corresponds to the baffle or the rotating shaft, the position of the baffle can be determined to ensure that the baffle is rotated into place.

[0013] In some possible designs, the position detection component includes: a detection member, which is arranged on the rotating shaft; a sensor, which is arranged on the base. When the baffle is in the first position, the sensor and the detection member are arranged opposite to each other, and when the baffle is in the second position, the sensor and the detection member are arranged offset.

[0014] In this design, the position detection component includes a detection member and a sensor. The detection member is arranged on the rotating shaft, and the sensor is arranged on the base. The driving member drives the baffle to rotate through the rotating shaft, that is, the rotation angle of the rotating shaft is the same as the rotation angle of the baffle. Therefore, the detection member is arranged on the rotating shaft, and the position of the baffle can be detected. Among them, when the baffle is in the first position, the sensor and the detection member are arranged relative to each other, and the sensor detects a signal, thereby determining that the baffle is in the first position. When the baffle is in the second position, the sensor and the detection member are misaligned, and the sensor cannot detect a signal.

[0015] In some possible designs, the sensor includes any of the following: a proximity sensor, a slot sensor, a reflective sensor.

[0016] In this design, the sensor includes any one of a proximity sensor, a slot sensor, and a reflective sensor.

[0017] In some possible designs, the blocking device further includes: at least two bearing seats disposed on the base, the rotating shaft is rotatably disposed on the at least two bearing seats, and the sensor is disposed between the at least two bearing seats.

[0018] In this design, the blocking device further includes at least two bearing seats, which are arranged on the base and used to support the rotating shaft, and the rotating shaft can rotate relative to the at least two bearing seats, thereby driving the baffle to rotate between the first position and the second position. The sensor is arranged between the at least two bearing seats to detect the position of the baffle.

[0019] In some possible designs, the blocking device further includes: a first limit block, which is disposed on the base. When the baffle is located at the first position, the first limit block is located at the bottom of the baffle, and the baffle cooperates with the first limit block in a limiting manner.

[0020] In this design, the blocking device also includes a first limit block, which is arranged on the base and located at the bottom of the baffle. When the baffle is in the first position, the first limit block supports the baffle at the bottom of the baffle to limit the baffle, avoid the baffle from rotating beyond the limit, and prevent accidents.

[0021] In some possible designs, the blocking device further includes: a second limit block, which is arranged on the base and located at the bottom of the baffle, and the first limit block and the second limit block are located on opposite sides of the rotation axis of the baffle.

[0022] In this design, the blocking device also includes a second limit block, which is arranged on the base and located at the bottom of the baffle. The first limit block and the second limit block are located on opposite sides of the rotation axis of the baffle, so that the second limit block can prevent the baffle from rotating more than 180° to avoid damage to other components.

[0023] In some possible designs, the rotation axis of the baffle is arranged along the transmission direction; the baffle is in a strip shape, and the extension direction of the baffle is perpendicular to the rotation axis direction of the baffle.

[0024] In this design, the rotation axis of the baffle is arranged along the transmission direction of the roller conveyor line, so that the baffle can block the material at the end of the roller conveyor line to prevent the material from falling from the roller conveyor line.

[0025] In some possible designs, the baffle located at the first position is perpendicular to the baffle located at the second position.

[0026] In this design, the baffle at the first position is perpendicular to the baffle at the second position, that is, the baffle rotates 90° from the first position to the second position, and correspondingly, the baffle rotates 90° from the second position to the first position to the first position, which can not only reduce the overall volume of the blocking device when the baffle rotates to the bottom of the roller transmission line, but also ensure the blocking height of the material when the baffle is in the second position to ensure the blocking effect.

[0027] According to the second aspect of the utility model, an automatic guided transport vehicle is also proposed, comprising: a roller conveyor line; and a blocking device as proposed in any one of the first aspects, wherein the blocking device is located at at least one of the two ends of the roller conveyor line along the transmission direction of the roller conveyor line.

[0028] The automatic guided transport vehicle provided in the second aspect of the utility model comprises the blocking device proposed in any of the above technical solutions, and therefore has all the beneficial effects of the blocking device.

[0029] In some possible designs, the automatic guided transport vehicle also includes: a main body, a roller conveyor line and a blocking device arranged on the main body, the roller conveyor line is arranged in at least two layers, and a blocking device is correspondingly provided at at least one end of any layer of roller conveyor line along the transmission direction.

[0030] In this design, the automatic guided transport vehicle also includes a body, a roller conveyor line and a blocking device are arranged on the body, and the body can move, thereby driving the material on the roller conveyor line to move, thereby realizing the automatic guided transport function. Among them, the roller conveyor line is arranged in at least two layers, which increases the material conveying volume, improves the conveying efficiency, and also reduces the horizontal occupation of the space. A blocking device is arranged at least at one end of the conveying direction of any layer of roller conveyor line. On the one hand, the blocking device can block the material at at least one end of any roller conveyor line to prevent the automatic guided transport vehicle from falling from any end of the conveying direction during the movement; on the other hand, since the roller conveyor line is arranged in at least two layers, the space in the stacking direction of at least two layers of roller conveyor lines is small, and the baffle in the blocking device can rotate between the first position and the second position, so that the blocking device is only rotated to the second position when it is necessary to block the material, and when it is not necessary to block the material, it is rotated to the bottom of the roller conveyor line, thereby reducing the occupation of the roller conveyor line space.

[0031] In some possible designs, any layer of roller conveyor line includes a plurality of rollers arranged along the transmission direction, and the blocking device is arranged corresponding to the middle of the roller along the rotation axis direction of the roller.

[0032] In this design, any layer of roller conveyor line includes multiple rollers arranged along the transmission direction, and the rollers rotate to realize the movement of materials. Along the rotation axis direction of the rollers, the blocking device is set corresponding to the middle of the rollers, which improves the blocking effect on the materials and reduces the space occupied by the roller conveyor line.

DETAILED DESCRIPTION

[0042] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0044] Refer to the following Figures 1 to 5 The blocking device 1 and the automatic guided transport vehicle 2 proposed according to some embodiments of the present utility model are described.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, according to one embodiment of the utility model, the utility model proposes a blocking device 1, which is used for an automatic guided transport vehicle 2. The automatic guided transport vehicle 2 includes a roller conveyor line 20. 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. The blocking device 1 includes: a base 10, a drive assembly 11 and a baffle 12.

[0046] Specifically, the base 10 is located at the bottom of the roller conveyor line 20; the drive assembly 11 is connected to the base 10 and is located at the bottom of the roller conveyor line 20; the baffle 12 is connected to the drive assembly 11, and the drive assembly 11 is used to drive the baffle 12 to rotate between a first position and a second position; when the baffle 12 is located at the first position, the baffle 12 is located at the bottom of the roller conveyor line 20; when the baffle 12 is located at the second position, at least a portion of the baffle 12 protrudes from the working surface of the roller conveyor line 20, and is used to block the material on the roller conveyor line 20.

[0047] The blocking device 1 provided by the utility model is used for an automatic guided transport vehicle 2, which includes a roller conveyor line 20. Along the transmission direction of the roller conveyor line 20, the blocking device 1 is arranged at least one of the two ends of the roller conveyor line 20 to block materials at at least one of the two ends of the roller conveyor line 20. The blocking device 1 includes a base 10, a drive assembly 11 and a baffle 12. The base 10 and the drive assembly 11 are both arranged at the bottom of the roller conveyor line 20 to avoid affecting the loading and unloading process of the roller conveyor line 20. The driving assembly 11 is arranged on the base 10, and the baffle 12 is connected to the driving assembly 11. The driving assembly 11 can drive the baffle 12 to rotate between the first position and the second position: when the baffle 12 is in the first position, the baffle 12 is located at the bottom of the roller conveyor line 20 to avoid affecting the loading and unloading process; when the baffle 12 is in the second position, at least a part of the baffle 12 protrudes from the working surface of the roller conveyor line 20, and is used to block the materials on the roller conveyor line 20 to prevent the automatic guided transport vehicle 2 from falling from the roller conveyor line 20 due to acceleration or turning. At the same time, the driving assembly 11 is used to drive the baffle 12 to rotate between the first position and the second position, so that the blocking device 1 is located at the bottom of the roller conveyor line 20 when it rotates back to the first position, which has a small size, a simple structure, and saves costs, thereby avoiding occupying the space of the automatic guided transport vehicle 2.

[0048] Optionally, the baffle 12 rotates from the first position to the second position by an angle greater than or equal to 80° and less than or equal to 100°.

[0049] Optionally, when the baffle 12 is in the first position, the baffle 12 is arranged in the horizontal direction, and when the baffle 12 is in the second position, the baffle 12 is arranged in the vertical direction.

[0050] Specifically, the baffle 12 rotates from the first position to the second position by an angle of 90°.

[0051] It is understandable that the working surface of the roller conveyor line 20 is capable of carrying and conveying materials.

[0052] like Figure 1 and Figure 2 As shown, according to some embodiments of the present application, optionally, the driving assembly 11 includes: a driving member 110, which is disposed on the base 10; a rotating shaft 112, one end of the rotating shaft 112 is connected to the driving member 110, and the other end is connected to the baffle 12.

[0053] In this embodiment, the driving assembly 11 includes a driving member 110 and a rotating shaft 112. The driving member 110 is arranged on the base 10. The rotating shaft 112 is connected to the driving member 110 and the baffle 12. The driving member 110 drives the baffle 12 to rotate between a first position and a second position through the rotating shaft 112, so as to reduce the space occupied by the blocking device 1 as a whole when the baffle 12 is in the first position, and achieve blocking of the material when the baffle 12 is in the second position.

[0054] Optionally, the driving member 110 includes any one of a motor and a motor-reducer integrated machine.

[0055] like Figure 4 As shown, according to some embodiments of the present application, optionally, the blocking device 1 further includes: a position detection component 13 corresponding to the baffle 12 or the rotating shaft 112 , and used to detect the position of the baffle 12 .

[0056] In this embodiment, the blocking device 1 also includes a position detection component 13, which corresponds to the baffle 12 or the rotating shaft 112. The rotating shaft 112 and the baffle 12 can rotate simultaneously under the action of the driving member 110. Therefore, when the position detection component 13 corresponds to the baffle 12 or the rotating shaft 112, the position of the baffle 12 can be determined to ensure that the baffle 12 is rotated into place.

[0057] like Figure 4 As shown, according to some embodiments of the present application, optionally, the position detection component 13 includes: a detection member 130, which is arranged on the rotating shaft 112; a sensor 132, which is arranged on the base 10, and when the baffle 12 is located in the first position, the sensor 132 and the detection member 130 are arranged opposite to each other, and when the baffle 12 is located in the second position, the sensor 132 and the detection member 130 are arranged in an offset manner.

[0058] In this embodiment, the position detection component 13 includes a detection member 130 and a sensor 132. The detection member 130 is arranged on the rotating shaft 112, and the sensor 132 is arranged on the base 10. The driving member 110 drives the baffle 12 to rotate through the rotating shaft 112, that is, the rotation angle of the rotating shaft 112 is the same as the rotation angle of the baffle 12. Therefore, the detection member 130 is arranged on the rotating shaft 112, and the position of the baffle 12 can be detected. Among them, when the baffle 12 is in the first position, the sensor 132 is arranged relative to the detection member 130, and the sensor 132 detects a signal, thereby determining that the baffle 12 is in the first position. When the baffle 12 is in the second position, the sensor 132 and the detection member 130 are misaligned, and the sensor 132 cannot detect a signal.

[0059] According to some embodiments of the present application, optionally, the sensor 132 includes any one of the following: a proximity sensor, a slot sensor, and a reflective sensor.

[0060] In this embodiment, the sensor 132 includes any one of a proximity sensor, a slot sensor, and a reflective sensor.

[0061] In a specific application, the sensor 132 is a proximity sensor, the detection member 130 is a detection pin, and the detection pin is fixed on the rotating shaft 112. When the baffle 12 is in the first position, the detection pin is facing the proximity sensor, and the proximity sensor detects a signal state. When the detection pin does not correspond to the proximity sensor, the proximity sensor cannot detect a signal.

[0062] Optionally, when the sensor 132 is a slot sensor, the detection member 130 is a metal member, and when the baffle 12 is in the first position, the metal member extends into the slot of the slot sensor, and the slot sensor detects a signal state. When the metal member is removed from the slot of the slot sensor, the slot sensor cannot detect a signal.

[0063] Optionally, when the sensor 132 is a reflective sensor, the detection element 130 is a reflective sheet. When the baffle 12 is in the first position, the reflective sheet reflects the light emitted by the reflective sensor to the reflective sensor, and the reflective sensor detects a signal. When the reflective sheet rotates with the rotating shaft 112, it cannot reflect the light, and the reflective sensor cannot detect any signal.

[0064] like Figure 1 As shown, according to some embodiments of the present application, optionally, the blocking device 1 also includes: at least two bearing seats 14, which are arranged on the base 10, the rotating shaft 112 is rotatably arranged on the at least two bearing seats 14, and the sensor 132 is arranged between the at least two bearing seats 14.

[0065] In this embodiment, the blocking device 1 further includes at least two bearing seats 14, which are disposed on the base 10 and are used to support the rotating shaft 112. The rotating shaft 112 can rotate relative to the at least two bearing seats 14, thereby driving the baffle 12 to rotate between the first position and the second position. The sensor 132 is disposed between the at least two bearing seats 14 to detect the position of the baffle 12.

[0066] like Figure 2 As shown, according to some embodiments of the present application, optionally, the blocking device 1 also includes: a first limit block 15, which is provided on the base 10, and when the baffle 12 is in the first position, the first limit block 15 is located at the bottom of the baffle 12, and the baffle 12 and the first limit block 15 are limited and cooperated.

[0067] In this embodiment, the blocking device 1 also includes a first limit block 15, which is arranged on the base 10 and is located at the bottom of the baffle 12. When the baffle 12 is in the first position, the first limit block 15 supports the baffle 12 at the bottom of the baffle 12 to limit the baffle 12, avoid the baffle 12 from rotating beyond the limit, and prevent accidents.

[0068] It is understandable that when the baffle 12 is in the first position, the baffle 12 is limited by the support of the first limit block 15, and the drive component 11 does not need to output power to keep the baffle 12 in the first position, thereby reducing the energy consumption of the drive component 11.

[0069] like Figure 2 As shown, according to some embodiments of the present application, optionally, the blocking device 1 also includes: a second limit block 16, which is provided on the base 10 and located at the bottom of the baffle 12, and the first limit block 15 and the second limit block 16 are located on opposite sides of the rotation axis of the baffle 12.

[0070] In this embodiment, the blocking device 1 also includes a second limit block 16, which is arranged on the base 10 and located at the bottom of the baffle 12. The first limit block 15 and the second limit block 16 are located on opposite sides of the rotation axis of the baffle 12, so that the second limit block 16 can prevent the baffle 12 from rotating more than 180° to avoid damage to other components.

[0071] Optionally, a limiting groove is provided on the baffle 12. When the baffle 12 rotates to the position where the second limiting block 16 is located, the second limiting block 16 can be engaged with the limiting groove to prevent the baffle 12 from continuing to rotate.

[0072] According to some embodiments of the present application, optionally, the rotation axis of the baffle 12 is arranged along the transmission direction; the baffle 12 is strip-shaped, and the extension direction of the baffle 12 is perpendicular to the rotation axis direction of the baffle 12.

[0073] In this embodiment, the rotation axis of the baffle 12 is arranged along the transmission direction of the roller conveyor line 20 , so that the baffle 12 can block the material at the end of the roller conveyor line 20 to prevent the material from falling from the roller conveyor line 20 .

[0074] Optionally, the baffle 12 is in a strip shape.

[0075] Optionally, the extension direction of the baffle 12 is perpendicular to the rotation axis direction of the baffle 12 .

[0076] According to some embodiments of the present application, optionally, the baffle 12 located at the first position is perpendicular to the baffle 12 located at the second position.

[0077] In this embodiment, the baffle 12 at the first position is perpendicular to the baffle 12 at the second position, that is, the baffle 12 rotates 90° from the first position to the second position, and correspondingly, the baffle 12 rotates 90° from the second position to the first position to the first position, which can not only reduce the overall volume of the blocking device 1 when the baffle 12 rotates to the bottom of the roller 24 transmission line, but also ensure the blocking height of the material when the baffle 12 is in the second position to ensure the blocking effect.

[0078] 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.

[0079] 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.

[0080] In a specific application, the blocking device 1 is arranged at both ends of the roller conveyor line 20 along the transmission direction of the roller conveyor line 20, so that the material can be blocked at both ends of the roller conveyor line 20 to prevent the material from falling during the movement or loading and unloading process.

[0081] 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 layers, and a blocking device 1 is correspondingly provided at at least one end of any layer of the roller conveyor line 20 along the transmission direction.

[0082] In this embodiment, the automatic guided transport vehicle 2 further includes a body 22, on which the roller conveyor line 20 and the blocking device 1 are arranged, and the body 22 can move, thereby driving the material on the roller conveyor line 20 to move, thereby realizing the automatic guided transport function. Among them, the roller conveyor line 20 is arranged in at least two layers, which increases the material conveying volume, improves the conveying efficiency, and also reduces the horizontal occupation of the space. A blocking device 1 is provided at least at one end of any layer of roller conveyor line 20 in the conveying direction. On the one hand, the blocking device 1 can block the material at at least 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; on the other hand, since the roller conveyor line 20 is arranged in at least two layers, the space in the stacking direction of at least two layers of roller conveyor lines 20 is small, and the baffle 12 in the blocking device 1 can rotate between the first position and the second position, so that the blocking device 1 is only rotated to the second position when it is necessary to block the material, and rotated to the bottom of the roller conveyor line 20 when it is not necessary to block the material, thereby reducing the space occupied by the roller conveyor line 20.

[0083] It can be understood that the roller conveyor line 20 is arranged in at least two layers along the vertical direction.

[0084] Optionally, blocking devices 1 are provided at both ends of any layer of roller conveyor line 20 along the transmission direction.

[0085] Optionally, any layer of roller conveyor lines 20 includes at least two rows of roller conveyor lines 20 .

[0086] like Figure 5 As shown, according to some embodiments of the present application, optionally, any layer of roller conveyor line 20 includes a plurality of rollers 24 arranged along the transmission direction, and along the rotation axis direction of the roller 24, the blocking device 1 is arranged corresponding to the middle of the roller 24.

[0087] In this embodiment, any layer of roller conveyor line 20 includes a plurality of rollers 24 arranged along the transmission direction, and the rollers 24 rotate to realize the movement of the material. Along the rotation axis direction of the roller 24, the blocking device 1 is arranged corresponding to the middle part of the roller 24, which improves the blocking effect on the material and reduces the space occupied by the roller conveyor line 20.

[0088] Optionally, the blocking device 1 proposed in the present application is used for an automated guided vehicle 2 (AGV) having a double-layer roller conveyor line 20. Because the double-layer roller AGV is docked with the conveyor line and its height is limited, the size of the blocking device 1 is limited. The blocking device 1 proposed in the present application has a simple structure and a reduced volume, thereby being able to block materials on the double-layer roller AGV.

[0089] In some specific applications, due to size limitations, it is not possible to block the left and right positions, and it is necessary to block from the top and bottom. The present application blocks from the middle, and only one set of blocking mechanism (such as blocking device 1) is required on one side, which is easy to install and saves costs.

[0090] This application is used in scenarios where the left and right dimensions are limited and the device is installed directly below.

[0091] Specifically, the present application proposes a blocking mechanism for a roller AGV, including an outermost blocking plate (such as a baffle 12), a rotating shaft 112 connected to the blocking plate, driven by an integrated motor reducer, a bearing seat 14 arranged at the axial end position of the rotating shaft 112, and a detection pin fixed to the rotating shaft 112 by a screw, and a proximity sensor is used to detect whether it is in place.

[0092] Specifically, the blocking plate is located at the end of the rotating shaft 112, and the motor reducer integrated machine is connected to the rotating shaft 112 through a coupling. The proximity sensor is located in the middle of the two bearing seats 14, and the limit blocks (such as the first limit block 15 and the second limit block 16) are located below the blocking plate. Figure 2 As shown, the limit blocks are located on both sides of the center of the rotating shaft 112 to prevent the blocking plate from rotating beyond the designed angle. The two bearing seats 14 are mounted on a fixed plate (such as a base 10), and the motor mounting plate of the motor reducer integrated machine is also fixed on the fixed plate.

[0093] In the normal state (for example, when the baffle 12 is in the first position), the baffle is in a laid-down state and parallel to the ground. At this time, the entire blocking mechanism is located below the roller line of the AGV (for example, the roller conveyor line 20), and does not affect the conveying of materials by the roller 24. In the normal state, the detection pin is also in a parallel position to the ground and is facing the proximity sensor. At this time, the proximity sensor is in a state of detecting a signal.

[0094] In the working state (for example, when the baffle 12 is in the second position), when the motor reducer integrated machine receives the signal, it rotates 90° clockwise to Figure 3 At this time, the blocking plate will extend out of the working surface of the roller 24 to block the materials on the roller line to prevent the materials from being thrown out due to acceleration, deceleration, turning and other working conditions of the AGV.

[0095] To prevent accidents, limit blocks are installed on both sides below the blocking plate to provide dead limits to prevent accidents from damaging other parts when the blocking plate rotates more than 180°.

[0096] The blocking mechanism for roller AGV proposed in the present application has a small structure, is suitable for places with small installation space, is easy to install, and only one set of blocking mechanism is needed each time to achieve the blocking purpose.

[0097] Optionally, the combined induction detection device of the proximity sensor and the detection pin can also be replaced by other types of sensors, such as slot sensors, reflection sensors, etc.
