Embodiment
Judge the alert area of super large forging press tool according to gross data, as shown in Figure 1, three erection columns 1,2,3 are erected at respectively to the same side of metal forming machinery, three erection column 1,2,3 positioned opposite triangular in shape form triangle warning region.
As shown in Figure 2,3, two rows are installed on erection column 1, three photoelectric sensor switches of every row, one row is 4A, 5A, 6A, another row is 4B, 5B, 6B.
Two rows are installed on erection column 2, three photoelectric sensor switches of every row, one row is 7A, 8A, 9A, another row is 7B, 8B, 9B.
Two rows are installed on erection column 3, three photoelectric sensor switches of every row, one row is 10A, 11A, 12A, another row is 10B, 11B, 12B.
Install behind the position of three erection columns 1,2,3, adjust respectively the relative position of nine couples of photoelectric sensor switch 4A and 7B, 5A and 8B, 6A and 9B, 7A and 10B, 8A and 11B, 9A and 12B, 10A and 4B, 1 1A and 5B, 12A and 6B, make every pair of coupling separately, altogether form nine pairs of optoelectronic switches (4A and 7B, 5A and 8B, 6A and 9B, 7A and 10B, 8A and 11B, 9A and 12B, 10A and 4B, 1 1A and 5B, 12A and 6B) with this.Nine couples of optoelectronic switch corresponding nine relay: 4A relay K A1s corresponding to 7B of startup that control respectively, 5A relay K A2 corresponding to 8B, 6A relay K A3 corresponding to 9B, 7A relay K A4 corresponding to 10B, 8A relay K A5 corresponding to 11B, 9A relay K A6 corresponding to 12B, 10A relay K A7 corresponding to 4B, 1 1A relay K A8 corresponding to 5B, 12A relay K A9 corresponding to 6B.
As shown in Figure 4, alarm buzzer L1 and relay K A2, relay K A3 are connected on to a DC electrical source E1 above, and it is upper that relay K A1 is connected in parallel on to relay K A3, forms the first warning circuit with this.
As shown in Figure 5, alarm buzzer L2 and relay K A5, relay K A6 are connected on to a DC electrical source E2 above, and it is upper that relay K A4 is connected in parallel on to relay K A6, forms the second warning circuit with this.
