Further, go up assembly line 2 and set up a plurality of stations along its direction of transfer, every station all sets up the gyro wheel and blocks cylinder 21 and control the gyro wheel and block the station switch of cylinder 21 motion, the station switch sets up to foot-operated switch, and the station switch includes reset state and steps on the state, and in reset state, the gyro wheel blocks that cylinder 21 blocks that the piece offsets with the breach 41 of frock board 4, and in stepping on the state, the gyro wheel blocks that cylinder 21 blocks that the piece moves to breach 41 below.

On every station, the workman operates the station switch, and is pedal through trampling, and the gyro wheel blocks cylinder 21 downstream, can let pass frock board 4 on the current station, goes up assembly line 2 and lower assembly line 3 and all sets up to doubly fast chain assembly line, doubly fast chain assembly line is moving all the time, directly conveys next station after frock board 4 lets pass, and the frock board 4 of last station can be transported to on this station.

The upper production line 2 is provided with a candidate area triggering part 22, the sensing mechanism comprises a protection triggering part 142 and a lifting triggering part 143 which are sequentially arranged along the direction that the tooling plate 4 enters the lifting device 1, and the distance between the protection triggering part 142 and the lifting triggering part 143 is smaller than the length of the tooling plate 4 in the transmission direction;

the tooling plate 4 blocked by the roller blocking cylinder 21 closest to the lifting device 1 is the first station of the upper production line 2, a candidate area is arranged at the more upstream of the station, when the tooling plate 4 on the first station needs to be conveyed to the downstream, the tooling plate 4 in the candidate area moves to the first station under the driving of the double-speed chain, and a trigger 22 of the candidate area is used for ensuring that the candidate area always has a new tooling plate 4 to supplement the first station.

The candidate area triggering member 22 may be disposed under the tooling plate 4 of the first station to detect the presence or absence of the tooling plate 4 at the position, or may be disposed under the candidate area to detect the presence or absence of the tooling plate 4, in particular, in the present embodiment, as shown in fig. 5, the candidate area triggering member 22 is disposed under the candidate area, the operation logic is clearer and more accurate, the tooling plate 4 is always present in the candidate area, the tooling plate 4 is immediately adjacent to the tooling plate 4 of the first station, the lifting device 1 is in the lifted state at this time, the candidate area triggering member 22 is always in the triggered state, when the tooling plate 4 of the first station is transported away, the tooling plate 4 of the candidate area moves forward until the candidate area triggering member 22 is no longer triggered, which means that the state of the candidate area is empty at this time, the candidate area triggering member 22 is used to control the downward movement of the jacking cylinder 11, when the tooling plate 4 does not trigger the triggering member 22, the jacking cylinder 11 is switched from the lifting state to the falling state.

The conveying mechanism 12 is further provided with a protection trigger 142 and a lifting trigger 143 which are sequentially arranged along the direction that the tooling plate 4 enters the lifting device 1, when the lifting cylinder 11 drops the conveying mechanism 12, the conveying mechanism 12 can be started, the horizontal conveying belt 121 conveys the tooling plate 4 to the inside of the lifting device 1 all the time, when the tooling plate 4 is conveyed to the conveying mechanism 12 from the lower assembly line 3, the lifting cylinder 11 is static when the tooling plate 4 firstly triggers the protection trigger 142, the meaning is that the tooling plate 4 reaches the position, the lifting cylinder 11 is controlled not to move, the tooling plate 4 is prevented from not moving in place, the lifting cylinder 11 suddenly moves due to error touch or other reasons, the tooling plate 4 falls down, or the protection trigger 142 is equivalent to a switch, and the switch is triggered and closed by the entering tooling plate 4.

When the tooling plate 4 triggers the lifting trigger 143, the jacking cylinder 11 is switched from a falling state to a rising state; after the tooling plate 4 triggers the protection triggering part 142, the tooling plate continues to move into the lifting device 1 until the lifting triggering part 143 is triggered, at this moment, the conveying mechanism 12 can be controlled to stop conveying, the jacking cylinder 11 is opened, at this moment, the jacking cylinder 11 is switched to a rising state from a falling state, the tooling plate 4 is conveyed to the upper assembly line 2, namely, the protection triggering part 142 closes the jacking cylinder 11 firstly, the lifting triggering part 143 opens the jacking cylinder 11 again, and only when the two triggering parts are triggered, the upward movement of the jacking cylinder 11 is started.

After the upward movement reaches the lifting state, the motor 125 rotates reversely, the horizontal conveyor belt 121 conveys the tooling plate 4 to the outside of the lifting device 1 until the tooling plate is conveyed to the outer upper production line 2, a new tooling plate 4 triggers the candidate area triggering piece 22 again, so that the jacking cylinder 11 is static, namely, is always in the lifting state until the next candidate area triggering piece 22 stops triggering again, and when the tooling plate 4 does not trigger the candidate area triggering piece 22, the jacking cylinder 11 is switched from the lifting state to the falling state.

The length L of the tooling plate 4 in the transmission direction is set, one end of the upper assembly line 2 close to the lifting device 1, and the distance between the roller blocking cylinders 21 adjacent to the lifting device 1 is more than or equal to 2L and less than 3L, namely, only one tooling plate 4 is accommodated in the candidate area, so that the judgment logic of the trigger 22 of the candidate area can be clearer, and one tooling plate 4 is always kept in the candidate area.

And, in the conveying direction of the tooling plate 4, the distance between the roller-block cylinder 21 adjacent to the lifting device 1 and the candidate area triggering member 22 is larger than L, that is, the candidate area triggering member 22 is provided at the position of the candidate area, as described above, the control logic can be made clearer.

Further, the interruption trigger 141, the protection trigger 142, the lifting trigger 143, and the candidate area trigger 22 are all provided as travel switches, and the tooling plate 4 abuts against the travel switches, so that the travel switches can be rotated or pressed to trigger the operation thereof.

Of course, if the travel switch is set as an optoelectronic switch, the travel switch can be realized, but the cost of the travel switch is low, and the travel switch does not need to have more requirements on the control voltage and the design of a circuit structure like the optoelectronic switch, and the travel switch can be adopted to perfectly meet the use requirement.

Tooling plate 4 sets up to double-deck carousel formula tooling plate 4, and the sheet metal component is put at double-deck carousel formula tooling plate 4, conveniently rotates the position of arbitrary needs.
