The band concatenated intermediate point of machine contactor KM coil.The first output point DO1 of PLC is from PLC controller for remotely collecting
The start signal of the sealing-tape machine contactor KM of middle control.
After the coil of the second intermediate relay KA2 is connected with the first normally opened contact KM-1 of sealing-tape machine contactor KM
It is connected between 220V power supply.
Both ends also the second normally opened touching of the first intermediate relay KA1 of parallel connection of start button SBA opened point by the machine
Point KA1-2, the second normally opened contact KA1-2 are the self-locking control points of the first intermediate relay KA1 coil.The time relay
The second normally opened contact KM-2 of the both ends of the opened point of KT sealing-tape machine contactor KM also in parallel, the second normally opened contact KM-2 is adhesive tape
The self-locking control point of coil of machine contactor KM.
See Fig. 2, the first normally opened contact KA1-1 of the first intermediate relay KA1 and sealing-tape machine scene indication bell HB connect company
It is connected between 220V power supply.The second of the first both ends normally opened contact KA1-1 of first intermediate relay KA1 PLC also in parallel is defeated
The second output point DO2 of point DO2, PLC is the indication bell signal for long-distance centralized control from PLC controller out.
By the machine/concentrate selection switch SA, machine side start button SBA, machine side stop button SBB to be mounted on sealing-tape machine
Machine side operation box in.
The QF2 in QF1 and Fig. 2 in Fig. 1 is 1P breaker used in conventional control circuit.
Fig. 3 is the main loop circuit figure of sealing-tape machine operation motor M, successively includes that circuit breaker Q F, sealing-tape machine connect by power end
The main contacts of tentaculum, current transformer TA and sealing-tape machine motor M, the secondary terminals of current transformer TA have accessed hot protective relay
In KH, the design of sealing-tape machine operation motor M main circuit is the design of conventional motor main circuit.
Circuit theory of the invention is as follows:
By SA selection machine when mode of operation, by machine/the on-site control position SA-1 contact closure for selecting switch SA is concentrated, this
When press by machine after start button SBA, the first relay KA1 coil is powered simultaneously self-locking, while time relay KT coil is powered,
Indication electric bell HB1-HB3 is powered at this time, and indication ringing tone is sounded.After the delay of predetermined time, the energization of time relay KT
Delayed contact closure, the energization of sealing-tape machine contactor KM coil is simultaneously self-locking, and sealing-tape machine will start.Second relay KA2 coil at this time
It is powered, the normally-closed contact of the second relay KA2 disconnects, the first relay KA1 coil losing electricity, and indication bell ring terminates.
When mode of operation in SA choice set, by machine/the centralized control position SA-2 contact closure for selecting switch SA is concentrated, this
When, actuation and the indication bell of sealing-tape machine contactor KM are remotely directly controlled by PLC, the first output point DO1 of PLC controls sealing-tape machine
The actuation of contactor KM, the alarm of the second output point DO2 control indication bell HB-HB3 of PLC, delay function of the PLC inside
Can, delays time to control is actuated for early warning and sealing-tape machine automatically.
In Fig. 1, the second relay KA2's is introduced for eliminating that may be present in circuit compete and venture problem.Such as
It is the auxiliary contact schematic diagram of electromagnetic contactor shown in Fig. 4, since there are actuating lengths, after contactor coil is powered, often
The disconnection of closed contact is always prior to the closure of normally opened contact, and there are a small time difference Δ t between the two.If normally closed auxiliary with KM
The normally-closed contact for helping contact replacement KA2, when the delayed contact of time relay KT is closed, sealing-tape machine contactor KM coil is powered,
The normally-closed contact of KM will be disconnected first at this time, and is used for self-locking normally opened contact and is not yet closed, and sealing-tape machine contactor KM is not yet reliable
It is self-locking, since the normally-closed contact disconnection of sealing-tape machine contactor KM will lead to time relay KT power loss, if KT selects electronic type
Between relay, the delayed contact of KT will disconnect in very short time (< 10ms), if this response time is less than Δ t, sealing-tape machine is connect
Power loss is led to the self-locking failure of sealing-tape machine contactor KM by tentaculum KM coil, and sealing-tape machine will be unable to normally start.It is added among second
After relay KA2, that is, it can avoid the competition and venture problem in circuit, guarantee that sealing-tape machine can reliably start.
Above embodiments are implemented under the premise of the technical scheme of the present invention, give detailed embodiment and tool
The operating process of body, but protection scope of the present invention is not limited to the above embodiments.Method therefor is such as without spy in above-described embodiment
Not mentionleting alone bright is conventional method.
