Specific embodiment
Below in conjunction with Figure of description and specific embodiment, the invention will be further described.
As shown in Figure 1, the emergency stop device of the products storage circulation system of the present embodiment, including more than one emergency stop switch 1, respectively
The normally-closed contact all the way of emergency stop switch 1 is sequentially connected in series in the wire loop of rear whole safety relay 2 of connecting, for needing
After promptly pressing emergency stop switch 1 when emergency stop, the normally-closed contact of emergency stop switch 1 disconnects and cuts off the wire loop of safety relay 2
To disconnect the electrical source of power of products storage circulation system, the contact all the way of each emergency stop switch 1 accesses to Centralized Controller 3, for disconnected
Fault-signal is sent to Centralized Controller 3 while opening the electrical source of power of products storage circulation system and carries out fault location or/and event
Barrier display.Wherein in electrical source of power main circuit, electrical source of power main circuit is also in series with and collects the contact series of safety relay 2
Connected breaker/the contactor 6 of middle controller 3, Centralized Controller 3 can be realized by control breaker/contactor 6 to power electric
The on-off in source.The two contacts of emergency stop switch 1 are respectively connected to concentrate control by the emergency stop device of products storage circulation system of the invention
In the wire loop of device 3 and safety relay 2 processed, dual emergency stop control is carried out, the security reliability of sudden-stop function is improved, thus
Improve logistics system security reliability；And structure is simple, easy to operate and at low cost.
In the present embodiment, each emergency stop switch 1 be specifically installed on the operation bench of products storage circulation system and with each operation bench one
One is corresponding.The normally-closed contact all the way of each emergency stop switch 1 is connected in parallel to Centralized Controller 3, and Centralized Controller 3 is connected with display device 4,
It is shown for the state to emergency stop switch 1.Wherein display device 4 is HMI or host computer.Centralized Controller 3 has logic
