The specific embodiment
The related circuit of the utility model is integrated on 200 * 200 millimeters the wiring board, comprises compositions such as the normally-closed contact of normally opened contact, general-purpose relay of general-purpose relay, the time relay, general-purpose relay and contactor.In conjunction with Fig. 1 the utility model is described further:
After the long table of Speed frames meter fixed length arrives designated length and sends full yarn signal, the coil of first general-purpose relay (1) of described control circuit is connected, the normally opened contact closure of first general-purpose relay (1), negative power supply passes through five-way relay (5) from the normally opened contact of first general-purpose relay (1), the normally-closed contact of the 7th general-purpose relay (7) makes second general-purpose relay (2) coil adhesive, the normally opened contact closure of second general-purpose relay (2), because the normally opened contact of second general-purpose relay (2) is connected in parallel on the input terminal number 1 (13) of the input point 2 of Programmable Logic Controller, the normally-closed contact of 2 (14) and second general-purpose relay (2) is connected on the input terminal numbers 3 (16) of the input point 2 of optocoupler (15) and Programmable Logic Controller, at this moment negative power supply also can be from the normally opened contact of second general-purpose relay (2) by five-way with relay (5), the normally-closed contact of the 7th general-purpose relay (7) makes second general-purpose relay (2) coil adhesive.
Because the normally opened contact closure of first general-purpose relay (1) or second general-purpose relay (2) makes very first time relay (8) coil adhesive, the 3rd general relay (3) and second time relay (9) coil were connected in the time-delay of the normally opened contact of very first time relay (8) in 0.5 second, second time relay (9) coil the electric coil that makes second time relay (9) normally-closed contact time-delay disconnection in 1 second the 3rd general relay (3).
During the 3rd general relay (3) adhesive, number 1 (17) connection of the input terminal of the input point 1 of the Programmable Logic Controller of the normally opened contact control of the 3rd general relay (3), the super landing of Speed frames rail yarn is begun, another group normally opened contact of the 3rd general relay (3) is connected in parallel on the binding post numbers 1 (18), 2 (19) of line bank, the long table of meter is resetted, first general-purpose relay (1) coil losing electricity, the normally opened contact of first general-purpose relay (1) disconnects.
When the Speed frames rail rises, contactor (10) closure, four-way gets with relay (4) coil, for later five-way gets electric laying the first stone with relay, when outside rail secondary rising stop signal has input, the 6th general-purpose relay (6) closure, five-way gets with relay (5) coil, five-way disconnects with the normally-closed contact of relay (5), second general-purpose relay (2) coil disconnects, the normally opened contact of second general-purpose relay (2) disconnects simultaneously, and the whole process of doffing of Speed frames is all over and spinning once more.
Meet accident when working as Speed frames, the 7th general-purpose relay (7) will be worked, and the fuse (20) that cooperates electrode line to be provided with simultaneously can prevent current anomaly, and Speed frames are quit work.
By this control circuit, make the Speed frames error length of doffing be accurate to 1-2 rice, saved production cost.
