The vertical transmission mechanism can adopt various structural designs, such as a screw rod and nut transmission mechanism, a gear and rack transmission mechanism, a synchronous belt pulley transmission mechanism and the like, and the following crank swing transmission structure is preferably selected in the embodiment.
The motor shaft of the motor reducer 21 is sleeved on the near end of the crank 22, and the rotary locking end cover 24 is tightly pressed on the outer end of the motor shaft and locked by the shaft end locking screw 25. Therefore, when the motor shaft of the motor reducer 21 rotates, the near end of the crank 22 can be driven to rotate 360 degrees in a fixed-axis mode, and the far end of the crank 22 is connected with a group of rod end joint bearing assemblies 3;

The first rod end joint bearing 31 and the second rod end joint bearing 32 realize a flexible hinged connection mode of two ends between the crank 22 and the guide rail sliding block assembly 4, in the process that the motor speed reducer 21 drives the near end of the crank 22 to rotate along the circumference, the far end of the crank 22 flexibly and unimpededly transmits a swing driving force, and the first rod end joint bearing 31 and the second rod end joint bearing 32 of the rod end joint bearing assembly 3 ensure that the swing motion of the crank 22 along the circumferential direction is converted into vertical linear driving aiming at the guide rail sliding block assembly 4, so that the two ends of the crank swing transmission mechanism cannot be blocked.
The guide rail sliding block assembly 4 comprises a group of guide rails 41 fixedly connected with a guide rail fixing plate 12 through guide rail fixing screws 47, and a sliding block connecting plate 43 connected with a baffle 6 through a baffle connecting bolt 9, the sliding block 42 is fixedly connected with the sliding block connecting plate 43 through a sliding block fixing screw 46, the fixedly connected sliding block 42 is slidably nested in the guide rails 41, a driven rotating shaft 44 is fixedly arranged on the sliding block connecting plate 43, and the driven rotating shaft 44 is connected with the second rod end joint bearing 32 in a penetrating and sleeving manner and is locked at the shaft end by adopting a rotary connecting screw 8.
Furthermore, a limit induction sheet 45 is mounted on the slider connecting plate 43 through a limit fixing screw 48, correspondingly, a proximity switch 5 is mounted on the guide rail fixing plate 12, and the proximity switch 5 is used for inducing the initial position of the limit induction sheet 45, so that the limit effect on the vertical lifting stroke of the slider connecting plate 43 (finally, on the baffle 6) is achieved.
According to the work principle of the crank and the slide block, when the motor shaft drives the crank 22 to swing and rotate along the circumference, the slide block 42 drives the baffle 6 to move along the guide rail 41 in a reciprocating manner. When the crank 22 drives the slider connecting plate 43 to move to the far end of the motor shaft, the baffle 6 is lifted above the conveying plane of the roller conveying line 102, so that a block for the bin 103 is formed; when the crank 22 moves the slider connecting plate 43 to the proximal end of the motor shaft, the stop 6 descends below the transport plane of the roller conveyor line 102, and the bin 103 is no longer obstructed and can continue to be transported forward to the gripping area where the palletizing robot 101 is located.
By applying the electric bin stopping mechanism provided by the embodiment, the following electric bin stopping method is realized simultaneously in the application:
the whole electric stop mechanism of the material box is embedded below the conveying plane of the conveying line in a preset mode, the motor driving assembly 2 drives the baffle 6 to vertically lift along the guide rail sliding block assembly 4 through the vertical transmission mechanism, and when the baffle 6 is lifted above the conveying plane, the material box 103 is stopped from being conveyed forwards continuously; conversely, when the baffle 6 is lowered vertically below the conveying plane, the bin 103 is released and continues to be conveyed forward.
Further, the motor driving assembly 2 drives the baffle 6 to reciprocate vertically, according to the operation state of the stacking manipulator 101 for grabbing the bin 103, when the PLC of the roller conveying line 102 judges that the bin 103 in the grabbing area is full through photoelectric logic or visual equipment, the PLC sends a control instruction to the motor reducer 21 of the motor driving assembly 2, the motor reducer 21 is started, and at the moment, the baffle 6 rises to enter a stopping state to stop the bin 103 in the grabbing area from continuing to advance. The example of the stacker robot 101 grasping the bin in the figure is 3 at a time.
When the photoelectric or visual equipment detects that the material box 103 is grabbed and removed again, the PLC sends a control command to the motor speed reducer 21, the motor speed reducer 21 is started again, the baffle 6 descends reversely to enter a retraction state, and the material box 103 can move forward continuously without being blocked.
A motor shaft of the motor reducer 21 is sleeved on the near end of the crank 22, the first rod end joint bearing 31 is sleeved on the far end of the crank 22, the first rod end joint bearing 31 is connected with the second rod end joint bearing 32 through the adjusting nut 33, and the second rod end joint bearing 32 is in transmission connection with the sliding block connecting plate 43;
during the process that the motor reducer 21 drives the proximal end of the crank 22 to rotate along the circumference, the distal end of the crank 22 drives the baffle 6 to lift along the vertical direction through the rod end joint bearing assembly 3, namely, the rotation of the crank 22 in the circumferential direction is converted into the linear movement of the baffle 6.
Further, when the baffle 6 vertically goes up and down, the proximity switch 5 senses the moving position of the limit sensing sheet 45, so that the detection of the lifting stroke direction and distance of the baffle 6 is formed, and the limit of the baffle 6 relative to the vertical height of the conveying plane is controlled.
The bin electric stopping method comprises the following two control stages:
1) Stopping stage
The motor reducer 21 drives the near end of the crank 22 to rotate along the circumference, the slide block 42 drives the baffle 6 to ascend along the guide rail 41 until the slide block connecting plate 43 is positioned at the far end of the motor shaft, at the moment, the baffle 6 ascends vertically and moves to the conveying plane of the roller conveying line 102, and the baffle 6 stops the feed box 103 from continuously conveying forwards;
2) Retraction phase
The motor reducer 21 drives the near end of the crank 22 to rotate along the circumference, when the crank 22 drives the slide block connecting plate 43 to move to the near end of the motor shaft, the baffle 6 descends along the vertical direction to be lower than the conveying plane of the roller conveying line 102, and the feed box 103 is not obstructed any more and can continue to convey forwards.
