Further, the position sensor is arranged on the flushing valve door switch of texturing slot.
Further, the flushing valve door switch of the signal receiving/transmission device and texturing slot connects.
Further, the control processor is also associated with wireless communication device.
Further, the liquid lifetime monitoring apparatus is that a texturing slot corresponds to an individual liquid service life monitoring dress
It sets.
Further, the signal receiving/transmission device is that a texturing slot corresponds to an individual signal receiving/transmission device.
In conclusion by adopting the above-described technical solution, the utility model has the beneficial effects that：
1, in the utility model, system can realize that equipment full automation changes liquid, reduce manual labor's intensity, improve equipment
The degree of automation keep equipment more advanced and hommization；
2, in the utility model, changing liquid automatically is automatically brought into operation realization, and speed is faster than manual operation, improves the production time, together
When also can effectively avoid the error rate that manual operation changes liquid；
3, in the utility model, realize that the automatic decision to the groove body that conflicts replaces artificial observation to judge that groove body changes before liquid
If having detected, slot conflict can enter conflict and wait for, and wait for being initiated as soon changing liquid automatically after the completion of the groove body to conflict therewith changes liquid,
It avoids multiple groove bodies from being carried out at the same time to change liquid and cause a party to a conflict face that can prevent to think that the operation that error in judgement is brought is primary completely, separately
On the one hand manpower is also saved.
3, in the utility model, it only need to increase related device and component in original texturing slot, original etching device not be transformed,
Equipment cost will not be increased.

Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
A kind of texturing slot changing liquid automatically system, as shown in Figure 1, including liquid lifetime monitoring apparatus, audible-visual annunciator, groove body
Conflict discriminating gear, control processor and display, the lifetime monitoring apparatus, the audible-visual annunciator, the groove body conflict
Discriminating gear, the display are connect with the control processor respectively, the liquid lifetime monitoring apparatus, the groove body conflict
Discriminating gear and the control processor are also connect with texturing slot respectively；
The liquid lifetime monitoring apparatus includes position sensor, the clock monitor chip that is connect with position sensor and with
The PLC of clock monitor chip connection；
Groove body conflict discriminating gear includes signal receiving/transmission device and the PLC that is connect with signal receiving/transmission device.
The position sensor is arranged on the flushing valve door switch of texturing slot.
The flushing valve door switch of the signal receiving/transmission device and texturing slot connects.
The control processor is also associated with wireless communication device.
The liquid lifetime monitoring apparatus is that a texturing slot corresponds to an individual liquid lifetime monitoring apparatus.
The signal receiving/transmission device is that a texturing slot corresponds to an individual signal receiving/transmission device.
Texturing slot itself is an existing automation equipment produced, but does not have the function of changing liquid automatically,
The utility model increases component and is connected with each module of corresponding texturing slot, completes changing liquid automatically.
Liquid lifetime monitoring apparatus is connect with texturing slot, and position sensor detects the flushing valve door state of texturing slot, making herbs into wool
Slot, which once completely changes liquid, to be terminated, and flushing valve door opens primary closing once, and clock monitor chip receives position sensor twice
Signal when start to the timing of liquid service life, according to the working condition of a whole set of etching device, judge liquid service life, Ke Nengwei
800min, the PLC being connect with clock monitor chip handle clock signal, when the timing of some clock monitor chip
When reaching 800min, output signal gives the PLC of clock monitor chip connection, and the PLC being connect with clock monitor chip sends out this
The texturing slot liquid liquid service life expires signal, transmits a signal to control processor, control processor to this texturing slot carry out from
Dynamic shielding, this step are worked normally in order to not influence other groove bodies.Control processor gives audible-visual annunciator output alarm signal,
Audible-visual annunciator is alarmed, and prompt personnel differentiate signal, control groove body conflict discriminating gear note that being simultaneously emitted by groove body and changing liquid conflict
It carries out groove body and changes liquid conflict judgement.Because etching device, which is multiple texturing slots, shares a fluid infusion bucket, the slot of fluid infusion bucket is shared not
It can be carried out at the same time and change liquid, so groove body, which changes before liquid starts, will be made whether that groove body changes liquid conflict judgement.
Groove body conflict the discriminating gear course of work be：Signal receiving/transmission device connection texturing slot changes liquid switch, detects texturing slot
Liquid on off state is changed, and sends out and receive signal.When a texturing slot is when carrying out changing liquid, changes liquid switch and open, the electricity of unlatching
Signal simultaneous transmission gives the signal receiving/transmission device being attached thereto, device to send out wireless signal to other making herbs into wool groove bodies, other making herbs into wool
The signal receiving/transmission device of groove body connection, which receives wireless signal and is transferred to the PLC being connect with signal receiving/transmission device and conflict, to be sentenced
Disconnected, the PLC being connect with signal receiving/transmission device will differentiate signal transmission to control processor.If changed there are one groove body
Liquid, while thering is other groove bodies liquid service life to expire and change liquid, control processor then judges to conflict, control processor control
Groove body enters the stand-by period, and carrying out next groove body drain again after conflict groove body is completed to match liquid changes liquid, if judging Lothrus apterus
Control processor control liquid service life overdue texturing slot carries out drain and changes the work that surges, control processor automatically after a few seconds
This process is easily completed by existing software program module.After the completion of texturing slot matches liquid, control processor control sound-light alarm is set
Preparation goes out acousto-optic hint, and expression changes liquid completion and can proceed with normal work.Signal receiving/transmission device circuit diagram is as shown in Figure 2.
The display being connect with controller can coordinate operation system of software worked to texturing slot changing liquid automatically service system
Cheng Jinhang is shown, can also carry out artificial operation and control.
Wireless communication device can be increased to connect with control processor, the working condition of texturing slot changing liquid automatically system is sent out
External wireless communication equipment is given, staff can coordinate the operating system in external wireless communication equipment automatic to texturing slot
The working condition for changing liquid system is monitored and carries out remote operation.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
