[0035] The stopping device of the embodiment of the present application is used to stop an object 60 transported by a conveyor line (not shown). The conveyor line transports the object 60 along a first direction D1. Figure 1 In the illustrated blocking device, only a portion of the object 60 is shown, and the object 60 cooperates with the blocking device through the shown portion.

[0036] In one application scenario, the object 60 includes a pallet and a diesel engine (finished product or semi-finished product) disposed in the pallet. The conveyor line conveys the diesel engine to a predetermined station, and the stopping device stops the pallet and the diesel engine therein. At the predetermined station, after the diesel engine is subjected to a predetermined treatment, the conveyor line can continue to convey the diesel engine along the first direction D1 or in the reverse direction of the first direction D1.

[0037] The blocking device includes a frame 10 and a base assembly 20, an adjustment assembly 30 and a blocking assembly 40 respectively arranged on the frame 10. The blocking assembly 40 is arranged on the base assembly 20 and is used to block the object 60. The base assembly 20 is movably arranged on the frame 10 along the first direction D1, and the adjustment assembly 30 is used to adjust the position of the base assembly 20 in the first direction D1, thereby adjusting the position of the blocking assembly 40 in the first direction D1, and further adjusting the stop position of the object 60 in the first direction D1.

[0038] See also Figures 4 to 6 . Figure 4 yes Figure 1 A schematic three-dimensional structure diagram of the stopping component 40 and the anti-retraction component 50 in the stopping device is shown. Figure 5 yes Figure 1 A first side view of the stopping assembly 40 and the anti-retraction assembly 50 in the stopping device is shown. Figure 6 yes Figure 1 A second side view of the stopping assembly 40 and the anti-retraction assembly 50 in the stopping device is shown.

[0039] In some embodiments, the stopping assembly 40 includes a stopping member 410 , a first driving member 420 , an anti-retraction member 510 and a second driving member 520 .

[0040] The blocking member 410 is arranged corresponding to the conveying path of the conveying line, and has a first blocking state and a first releasing state. Figure 1 The blocking member 410 in the blocking device is in a first blocking state. In the first blocking state, the blocking member 410 can block the object 60 from moving along the first direction D1. In the first release state, the blocking member 410 allows the object 60 to move along the first direction D1.

[0041] The first driving member 420 is used to apply a force to the blocking member 410 so that the blocking member 410 is selectively in the first blocking state or the first releasing state.

[0042] The anti-return member 510 is arranged corresponding to the conveying path of the conveying line, and has a second blocking state and a second releasing state. Figure 1 The anti-return member 510 in the blocking device is in the second blocking state. In the second blocking state, the anti-return member 510 can block the reverse movement of the object 60 along the first direction D1. In the second release state, the anti-return member 510 can allow the object 60 to move in the reverse direction of the first direction D1. The anti-return member 510 is configured to switch from the second blocking state to the second release state driven by the object 60 during the movement of the object 60 along the first direction D1 to avoid the object 60, and can be reset to the second blocking state after avoiding the object 60.

[0043] The second driving member 520 is used to drive the anti-retraction member 510 to switch from the second blocking state to the second releasing state.

[0044] During the process of the conveyor conveying the object 60 along the first direction D1, the object 60 drives the anti-return member 510 to move, so that the anti-return member 510 switches from the second blocking state to the second release state to avoid the object 60. After avoiding the object 60, the anti-return member 510 resets to the second blocking state, so that the object 60 cannot move in the opposite direction of the first direction D1. The stop member 410 in the first blocking state can block the object 60 from moving in the first direction D1. Thus, the blocking body device can stop the object 60 conveyed by the conveyor line and prevent the object 60 from moving backward. After stopping the object 60, the stop member 410 can be switched to the first release state by the first driving member 420, so that the conveyor continues to convey the object 60 along the first direction D1, or the anti-return member 510 can be switched to the second release state by the second driving member 520, so that the conveyor conveys the object 60 in the opposite direction of the first direction D1.

[0045] In order to switch between the second blocking state and the second releasing state, the anti-return member 510 may adopt the following structure.

[0046] In some embodiments, the base assembly 20 includes a first mounting seat 210. The anti-recoil member 510 is rotatably disposed on the first mounting seat 210 around a first rotation axis L1. The first rotation axis L1 is disposed parallel to the first direction D1. The anti-recoil member 510 has an inclined surface 511, which is located outside the first rotation axis L1 and is inclined relative to the first rotation axis L1. The inclined surface 511 is used to abut against the object 60 to form a transmission matching structure, thereby converting the linear motion of the object 60 along the first direction D1 into the reverse rotational motion of the anti-recoil member 510 around the second direction D2.

[0047] Please also read Figure 7 . Figure 7 yes Figure 1 The three-dimensional structural schematic diagram of the stopping device is shown in the state where the anti-retraction member 510 and the first mounting seat 210 are in abutment with each other.

[0048] The anti-retraction member 510 has a contact portion 513. The contact portion 513 and the inclined surface 511 are located at two opposite sides of the first rotation axis L1.

[0049] The center of gravity of the anti-return member 510 is located outside the first rotation axis L1, so that the anti-return member 510 can rotate around the first rotation axis L1 along the second direction D2 to the second blocking state under the action of its own gravity, and the anti-return member 510 can overcome its own gravity and rotate around the first rotation axis L1 in the opposite direction along the second direction D2 to the second release state when the object 60 moves along the first direction D1. In the second blocking state, the anti-return member 510 abuts against the first mounting seat 210 through the abutting portion 513.

[0050] When the anti-retraction member 510 is rotatably connected to the first mounting seat 210, the second driving member 520 may adopt the following structure.

[0051] The anti-retraction member 510 has a force-bearing portion 512 located outside the first rotation axis L1. Specifically, the force-bearing portion 512 is a roller.

[0052] The second driving member 520 includes a driving cylinder and a pushing member 523. The driving cylinder includes a first cylinder body 521 and a first piston rod 522. The pushing member 523 is arranged on the first piston rod 522. The pushing member 523 has a pushing plane 5231 perpendicular to the axial direction of the first piston rod 522. The area of ​​the pushing plane 5231 is larger than the area of ​​the cross section of the first piston rod 522. The pushing member 523 pushes against the force-bearing portion 512 through the pushing plane 5231. The second driving member 520 is used to push against the force-bearing portion 512 to drive the anti-retraction member 510 to rotate around the first rotation axis L1 along the second direction D2 to the second release state.

[0053] The working process of the anti-retraction member 510 is as follows:

[0054] When the object 60 moves along the first direction D1, it contacts the inclined surface 511 and drives the anti-return member 510 to rotate around the first rotation axis L1 along the second direction D2 to the second release state, so that the anti-return member 510 avoids the object 60. After the object 60 passes through the anti-return member 510, the object 60 is separated from the inclined surface 511, and the force of the object 60 on the anti-return member 510 is eliminated. Under the action of its own gravity, the anti-return member 510 moves in the opposite direction of the second direction D2 around the first rotation axis L1 until the abutting portion 513 of the anti-return member 510 abuts against the first mounting seat 210. At this time, the anti-return member 510 is in the second blocking state and is located on one side of the object 60 in the first direction D1, and can block the object 60 from moving in the opposite direction of the first direction D1. When the conveyor line needs to continue to convey the object 60 in the opposite direction of the first direction D1, the second driving member 520 is actuated so that the pushing member 523 pushes the force-bearing portion 512 of the anti-pushing member through the pushing plane 5231, so that the anti-return member 510 switches to the second release state.

[0055] In addition to the above-mentioned structure, the anti-retraction member 510 may also adopt other alternative structures.

[0056] In some other embodiments, the anti-return member 510 is slidably matched with the first mounting seat 210 in the vertical direction. When the object 60 moves along the first direction D1, the object 60 is driven to overcome gravity and rise to the second release state. The anti-return member 510 can descend to the second blocking state under the action of its own gravity.

[0057] In some other embodiments, an elastic member may also be provided to apply elastic force to the anti-return member 510, so as to replace gravity with elastic force, so that the anti-return member 510 can be switched from the second blocking state to the second release state under the action of an external force, and reset to the second blocking state after the external force is eliminated. In the case where the anti-return member 510 is rotatably connected to the first mounting seat 210, the elastic member may be a torsion spring, which applies torque to the anti-return member 510. Under the action of the torque, the anti-return member 510 is always in the second blocking state. Driven by the object 60, the anti-return member 510 overcomes the torque and switches to the second release state. After the external force applied by the object 60 to the anti-return member 510 is eliminated, the torque drives the anti-return member 510 to reset to the second blocking state.

[0058] In order to realize the switching between the first blocking state and the first releasing state, the stopping member 410 specifically adopts the following structure.

[0059] In some embodiments, the base assembly 20 also includes a second mounting seat 220. The stop member 410 is rotatably disposed on the second mounting seat 220 around the second rotation axis L2. The center of gravity of the stop member 410 is located outside the second rotation axis L2, so that the stop member 410 can rotate around the second rotation axis L2 along the third direction D3 to a first release state under the action of its own gravity. The first driving member 420 is used to push the stop member 410 to drive the stop member 410 to rotate in the opposite direction around the second rotation axis L2 along the third direction D3 to a first blocking state. The manner in which the first driving member 420 drives the stop member 410 is similar to the manner in which the second driving member 520 drives the anti-retraction member 510, which will not be repeated here.

[0060] Further, in some embodiments, the stop assembly 40 further includes a limiter 430 and a third drive member 440. The limiter 430 is slidably engaged with the second mounting seat 220 along the fourth direction D4. The third drive member 440 is used to drive the limiter 430 to move along the fourth direction D4 or in the reverse direction thereof, so that the limiter 430 is selectively in the first predetermined position. When the stop member 410 is in the first blocking state and the limiter 430 is in the first predetermined position, the limiter 430 abuts against the stop member 410 to limit the stop member 410 from rotating around the second rotation axis L2 along the third direction D3.

[0061] The working process of the stop member 410 is as follows:

[0062] When the stopping member 410 is required to stop the object 60, the first driving member 420 is actuated to push the stopping member 410 to drive the stopping member 410 to rotate in the opposite direction of the third direction D3 around the second rotation axis L2 to the first blocking state. The third driving member 440 drives the limiting member 430 to move along the fourth direction D4, so that the limiting member 430 is in the first predetermined position.

[0063] When the stopping member 410 is required to release the object 60, the third driving member 440 drives the limiting member 430 to move in the opposite direction of the fourth direction D4, so that the limiting member 430 exits the first predetermined position. The first driving member 420 is actuated to cancel the force acting on the stopping member 410, so that the stopping member 410 rotates around the second rotation axis L2 along the third direction D3 to the first release state under the action of its own gravity.

[0065] In some embodiments, the base assembly 20 includes a first mounting seat 210, a second mounting seat 220, and a buffer member 230. The second mounting seat 220 can move relative to the first mounting seat 210 along the first direction D1 or in the opposite direction thereof. When the second mounting seat 220 is in the second predetermined position relative to the first mounting seat 210, it abuts against the first mounting seat 210 along the first direction D1. The buffer member 230 is configured to buffer the impact force of the first direction D1 on the second mounting seat 220. Among them, the anti-retraction member 510 is arranged on the first mounting seat 210, and the stop member 410 is arranged on the second mounting seat 220.

[0066] Specifically, the first mounting seat 210 includes a first mounting body 211 and a first limiting portion 212. The first mounting body 211 is slidably matched with the frame 10 along the first direction D1. The first limiting portion 212 is arranged on the first mounting body 211. The second mounting seat 220 includes a second mounting body 221 and a second limiting portion 222. The second mounting body 221 is slidably matched with the frame 10 in the first direction D1. The second limiting portion 222 is arranged on the second mounting body 221. The second limiting portion 222 and the first limiting portion 212 are spaced apart in the first direction D1, and the second limiting portion 222 is used to abut against the first limiting portion 212 along the first direction D1. The buffer 230 is a buffer cylinder, and the buffer cylinder includes a second cylinder body 231 and a second piston rod 232. The second piston rod 232 moves relative to the second cylinder body 231 in the first direction D1. The second cylinder body 231 is connected to the first mounting body 211, and the second piston rod 232 is connected to the second mounting body 221. In other embodiments, the second cylinder 231 may also be connected to the second installation body 221 , and the second piston rod 232 may be connected to the first installation body 211 . The anti-retraction member 510 is disposed on the first installation body 211 , and the stop member 410 is disposed on the second installation body 221 .

[0067] In this embodiment, the process of stopping the object 60 by the stopping component 40 is as follows:

[0068] The stopping member 410 is in a first stopping state, and the anti-retraction member 510 is in a second stopping state.

[0069] The conveyor conveys the object 60 along a first direction D1.

[0070] The object 60 moving in the first direction D1 pushes against the stopper 410 and drives the second mounting seat 220 to move in the first direction D1 relative to the first mounting seat 210. In this process, the buffer 230 can play a buffering role. In addition, the object 60 drives the anti-return member 510 to switch from the second stop state to the second release state, so that the object 60 passes over the anti-return member 510.

[0071] After the second mounting seat 220 abuts against the first mounting seat 210 along the first direction D1 , the stopping member 410 stops the object 60 from moving in the first direction D1 , and the anti-return member 510 returns to the second stopping state to prevent the object 60 from moving in the opposite direction of the first direction D1 .

[0072] By providing the buffer member 230 , the stopping device can be suitable for objects 60 with large mass or objects 60 being transported at high speed.

[0073] In some embodiments, the adjustment assembly 30 includes a transmission member 310 and a fourth drive member 320. The transmission member 310 is rotatably disposed on the frame 10 with the first direction D1 as the axis direction. The fourth drive member 320 is used to drive the transmission member 310 to rotate. The first mounting seat 210 and the second mounting seat 220 are respectively slidably matched with the frame 10 in the first direction D1, the buffer member 230 is respectively connected to the first mounting seat 210 and the second mounting seat 220, and the transmission member 310 forms a spiral transmission match with the first mounting seat 210, so that the rotational motion of the transmission member 310 is converted into the linear motion of the first mounting seat 210.

[0074] Specifically, the transmission member 310 is a screw rod. The fourth driving member 320 is a motor.

[0075] When the position of the stop assembly 40 in the first direction D1 needs to be adjusted, the fourth driving member 320 is actuated to drive the transmission member 310 to rotate, so that the first mounting seat 210 moves along the first direction D1. Since the buffer member 230 is connected to the first mounting seat 210 and the second mounting seat 220 respectively, when the first mounting seat 210 moves in the first direction D1, the second mounting seat 220 is also driven to move in the first direction D1.

[0076] In other embodiments, the transmission member 310 may also be coupled with the second mounting seat 220 in a spiral transmission so that the rotational motion of the transmission member 310 is converted into the linear motion of the second mounting seat 220. Since the buffer member 230 is connected to the first mounting seat 210 and the second mounting seat 220 respectively, when the second mounting seat 220 moves in the first direction D1, it also drives the first mounting seat 210 to move in the first direction D1.

[0077] The above-mentioned embodiments of the stop device can be combined with each other. Figures 1 to 9 ,introduce Figure 1 The working process of the stop device shown:

[0078] The fourth driving member 320 is actuated to drive the transmission member 310 to rotate, so that the rotational motion of the transmission member 310 is converted into the linear motion of the first mounting seat 210 along the first direction D1, so that the first mounting seat 210 moves to the target position in the first direction D1. The first mounting seat 210 drives the second mounting seat 220 to move synchronously through the buffer member 230.

[0079] The first driving member 420 is actuated to drive the blocking member 410 to rotate around the second rotation axis L2 in the opposite direction of the third direction D3 to a first blocking state.

[0080] The third driving member 440 is actuated to drive the limiting member 430 to move along the fourth direction D4 to the first predetermined position.

[0081] When the object 60 moves in the first direction D1, it pushes the stopper 410 and drives the second mounting seat 220 to move in the first direction D1 until the second mounting seat 220 abuts against the first mounting seat 210 in the first direction D1. In this process, the buffer 230 buffers the impact force in the first direction D1 on the second mounting seat 220. In addition, in this process, the anti-return member 510 is driven by the object 60 to switch from the second blocking state to the second release state and then reset to the second blocking state.

[0082] If the object 60 continues to be transported along the first direction D1, the third driving member 440 is controlled to move so that the limit member 430 exits the first predetermined position, and the first driving member 420 is controlled to move so that the first driving member 420 cancels the force applied to the stopping member 410, so that the stopping member switches to the first release state under the action of its own gravity.

[0083] If the object 60 is transported in the reverse direction of the first direction D1 , the second driving member 520 is controlled to operate, so that the second driving member 520 drives the anti-return member 510 to switch from the second blocking state to the second releasing state.

[0084] In summary, the stopping device in the embodiment of the present application can, after stopping the object 60, enable the conveyor line to continue conveying the object 60 in a predetermined direction or in its reverse direction.

[0085] The introduction provided in the above steps is only used to help understand the method, structure and core idea of ​​the present application. For ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
