Description
Technical field
The utility model relates to a kind of input circuit, the PLC input circuit of the dryer particularly during leather products hang airing.
Background technology
While existing extension skin dryer operating personnel carry out hanging skin, need other operating personnel to carry out switching manipulation at the operating area away from track, control the advance stopping etc. of chain.Waste time and energy, production efficiency is not high.
Utility model content
In order to overcome the shortcoming of prior art, the utility model provides hangs skin dryer PLC input circuit.
Technical solutions of the utility model are as follows:
Hang skin dryer PLC input circuit, comprise PLC chip, sensor input circuit, electrothermal relay input circuit, auxiliary reclay input circuit KA1, on-off circuit and power circuit, described sensor input circuit one end is connected with PLC chip, the other end connects power circuit, described electrothermal relay input circuit one end is connected with PLC chip, the other end connects power circuit, described auxiliary reclay input circuit KA1 one end is connected with PLC chip, the other end connects power circuit, described on-off circuit one end is connected with PLC chip, the other end connects power circuit, it is characterized in that: described sensor input circuit is used for receiving external signal, and by Signal transmissions to PLC chip, described electrothermal relay input circuit is used for motor in proterctive equipment or other power parts, described auxiliary reclay input circuit KA1 is used for the isolation of control circuit signal and transmission, described on-off circuit comprises chain advance switch and chain retreats switch, described chain advance switch S 7 paralleling switch S11, described chain retreats switch S 6 and S9 tandem tap S10.
Described switch S 10 and switch S 11 are installed concentratedly on foot-switch.
Described foot-switch is removable.
Described power circuit uses 24V voltage.
The utility model beneficial effect is: reduce by operating personnel, get, hang skin personnel and can arbitrarily control to hang skin frame stop position, improve production efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model circuit diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Consult Fig. 1.
Hang skin dryer PLC input circuit, comprise PLC chip, sensor input circuit FC1 to FC9, electrothermal relay input circuit QM1 to QM4, auxiliary reclay input circuit KA1, on-off circuit S1 to S9 and power circuit, described sensor input circuit FC1 to FC9 one end is connected with PLC chip, the other end connects power circuit, described electrothermal relay input circuit QM1 to QM4 one end is connected with PLC chip, the other end connects power circuit, described auxiliary reclay input circuit KA1 one end is connected with PLC chip, the other end connects power circuit, described on-off circuit S1 to S9 one end is connected with PLC chip, the other end connects power circuit, described sensor input circuit FC1 to FC9 is used for receiving external signal, and by Signal transmissions to PLC chip, described electrothermal relay input circuit QM1 to QM4 is used for motor in proterctive equipment or other power parts, described auxiliary reclay input circuit KA1 is used for the isolation of control circuit signal and transmission, described on-off circuit S1 to S9 comprises chain advance switch and chain retreats switch, described chain advance switch S 7 paralleling switch S11, described chain retreats switch S 6 and S9 tandem tap S10.
Described switch S 10 and switch S 11 are installed concentratedly on foot-switch.
Described foot-switch is removable.
Described power circuit uses 24V voltage, and in figure, 1 tunnel is high level 24V, and 2 tunnels are low level 0V.
Principle of work of the present utility model is: at chain advance switch S 7 paralleling switch S11, chain retreats switch S 6 and S9 tandem tap S10, and switch S 10 and S11 are installed concentratedly on a foot-switch, because pedal switch device is moveable connected mode for this reason, so when operating personnel is when manually hanging skin and needing frequent starting and stop machine, can start very easily and stop to hang skin machine, no longer need another employee to stand in operator's console side always and operate machines.Such saving personnel, and can the working time be saved.When not needing manually to hang skin, this pedal switch device being accepted, being placed on operator's console side, can not operation be hindered.
Above-mentioned drawings and Examples are only for illustration of the utility model, and any art those of ordinary skill to its suitable change done or modification, or is used other flower pattern instead and made this technical change, all should be considered as not departing from the utility model patent category.
