Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
The temporary holding rail 2 is inclined and inclined downward in the forward direction. The temporary staying track 2 is not provided with a driving motor, and the carrier naturally slides forwards and downwards depending on the self gravity.
On the temporary holding track 2, a distribution assembly 4 is provided, as shown in fig. 2, 3 and 4. In fig. 2, 3, and 4, the conveyance direction of the carrier is a direction from left to right in the drawing. The temporary holding track 2 is provided with a mounting plate 41, an upper blocking piece 44 and a lower blocking piece 43 are arranged above and below the mounting plate, and the two blocking pieces are driven by a lifting drive 45 to lift relative to the temporary holding track 2. The lifting drive 45 may use a solenoid valve and an air cylinder as in the prior art.
As shown in fig. 2 and 3, two or more vehicles close to each other, i.e., a front vehicle a and a rear vehicle B in fig. 3, are transported on the temporary holding track 2. As shown in fig. 3 and 4, the upper and lower blocking pieces are arranged in a staggered manner, and the lower blocking piece 43 is positioned further forward, i.e., in the right direction in the drawing. The carrier a is stopped by the lower stop plate 43 and cannot move forward continuously, and the lower stop plate 43 is provided with a stop surface 431 which is abutted against the carrier a.
As shown in fig. 2, the mounting plate 41 is rotatably connected to a paddle 42 including a hinge portion 421 and a sensing portion 422. A sensor, i.e., a magnetically sensitive switch 46, is also mounted on the mounting plate 41. When the carrier a slides to a designated position and is blocked by the lower blocking piece 43, the shifting piece 42 is shifted to rotate, the rotation of the sensing part 422 is sensed by the magnetic sensing switch 46, and after a designated time preset by the system, the system sends a descending instruction aiming at the lifting drive 45. Setting a suitable designated time here has two roles, one for controlling a suitable clearance time; the second action is that the carrier slides on the temporary holding track 2 due to the self-weight relationship, and a certain degree of swing exists, which affects the stability. The preset time can give the carrier stable time, and the controllability of the system is improved.
As shown in fig. 3 and 4, the lower barrier rib 43 and the upper barrier rib 44 are lowered at this time. The front of the vehicle A is not blocked by the lower blocking piece 43 and smoothly slides forwards. The carrier B at the rear is stopped by the upper stopper 44 so that it cannot advance. In addition, the upper barrier 44 includes a separation inclined pillar 441, which is designed to be obliquely separated and has an increased thickness in a direction from bottom to top, i.e., in a left-right direction in fig. 4. This allows the distance between the carriers a and B to be further increased when the upper barrier 44 is lowered.
Since the carrier A moves forward smoothly, the shifting piece 42 is not shifted any more, the shifting piece 42 resets due to self weight and does not sense the magnetic induction switch 46 any more, the action is captured by the system, and the control system controls the lifting drive 45 to ascend and reset.
During the resetting process, the front carrier a is pushed forward by the lower blocking piece 43. Specifically, as shown in fig. 4, a front pushing inclined surface 432 is provided at a front end surface of the lower blocking piece 43, and is inclined to extend forward gradually when being laid down from top to bottom. This causes the forward inclined surface 432 to push the front carrier a forward during the raising of the lower blocking piece 43, further increasing the distance between the two carriers.
Then the carrier B is stopped by the lower stop piece 43, and the above steps are repeated, so that a plurality of carriers which may be adhered to each other originally are separated and allocated one by one, and are sequentially conveyed on the track.
In addition, as shown in fig. 1, a full-load sensing device 5, which may be two photoelectric sensors arranged in tandem, is further disposed on the temporary stay track 2. When the time that the carrier passes through the two photoelectric sensors is within the preset time, it indicates that the situation on the temporary holding track 2 is normal and congestion does not exist, but if the time that the carrier passes through the two photoelectric sensors exceeds the preset time value, it indicates that congestion exists, the control system stops starting the operation of the track 1, and the phenomenon that the carrier on the temporary holding track 2 is derailed and dropped due to a plurality of carriers is avoided.
The carrier enters the transmission rail 3 after passing through the temporary holding rail 2, and the transmission rail 3 is also provided with a driving part such as a motor and the like to provide power. The conveying track 3 is further provided with a trigger sensor 31, the trigger sensor 31 can be a proximity sensor, and when a carrier is captured to pass through, whether the transportation of the conveying track 3 is suspended can be determined, so that the conveying track 3 can be matched with other tracks to avoid the carrier.
