Abstract

The utility model relates to a system for detecting a performance of a clearance adjustment encoder of a calendar. The system comprises a programmable controller; one end of the programmable controller is connected with a computer; an X0 terminal and an X1 terminal or an X3 terminal and an X4 terminal of a counter of the programmable controller are connected with an A terminal and a B terminal of a clearance adjustment encoder. The clearance adjustment encoder, the computer and the programmable controller are connected. A clearance adjustment motor is rotated forwardly or backwardly by one circle or several circles manually; the high-speed counter carries out pulse counting; and corresponding data changing in the computer is observed and on-line detection is carried out. Therefore, detection of an inner-side clearance adjustment encoder and an outer-side clearance adjustment encoder can be carried out under the circumstances that the running of a standby calender is not influenced and the standby calender can meet the machine operating requirement well to maintain normal operation of the equipment, thereby ensuring production continuity and stability.

Description

The detection system of encoder performance is adjusted in a kind of calender gap

Technical field

The utility model relates to the solar energy photovoltaic glass production technical field, and particularly the detection system of encoder performance is adjusted in a kind of calender gap.

Background technology

The energy ultrawhite figured glass panel that photovoltaic cell component adopts is a kind of comparatively special electronics industry glass, because its sheet thickness needed differs, while therefore producing original sheet glass, glass metal under molten condition, after the top roll through calender and lower roll are rubbed and push, forms glass plate.And the glass plate of producing different-thickness need to be realized by the gap of adjusting between top roll and lower roll.Operating personnel utilize the encoder data of touch-screen, carry out the operation that motor is adjusted in gap, the encoder of gap adjustment can accurately and rapidly reflect the variation of data, in process of production the top roll of calender and the clearance distance between lower roll are shown, thereby reach the purpose of producing and adjusting sheet thickness, for what produce, normally provided continuously assurance.But, the calender of reaching the standard grade is because the glass metal self-temperature is very high, make calender ambient temperature on every side also very high, being easy to that encoder is adjusted in gap causes hyperthermia radiation to damage, and after its calender rolls off the production line and becomes standby calender, because there is no corresponding trace routine and device, can't be detected it, thereby potential faults can't be found and discover, if use there has been or has soon damaged the standby calender of (unstable properties during high temperature) encoder, change again the words of line, will produce certain impact to the thickness of adjusting glass plate, incured loss through delay the qualified time of product, bring a certain amount of loss to the continuous and stable production of factory.

Usually the way that detects standby calender gap adjustment encoder quality is, after the melting stove is tied by flashboard, the calender of reaching the standard grade descends machine, and standby calender is when machine, plug all joints, all motors to calender are detected, and comprise the motor that gap is adjusted, the variation of observed data.If at this moment once encoder damages, (gap adjustment motor can move, but position can't be found out on display unit), so just can't be within the set time, changed operation, because the temperature of glass metal has met the needs of producing, must change standby calender, not have operation to alternate coding time of device at all, can only manually be regulated with ruler etc.This often need to be larger at the scene of high temperature workload, on producing, of short duration impact is also arranged; And manually adjustment also has certain error, therefore, carrying out the detection of adjusting encoder performance in standby calender gap, the frequency occurred that lessens the hidden dangers and the continuity that guarantees production how easily, targetedly is a very significant problem.

Summary of the invention

In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of calender gap to adjust the detection system of encoder performance, can be in the situation that do not affect the running of standby calender its inboard and outer side clearance adjustment encoder detected, make standby calender better meet the condition of machine, service equipment runs well, and guarantees the stability of producing.

In order to achieve the above object, the technical solution adopted in the utility model is: the detection system of encoder performance is adjusted in a kind of calender gap, comprise programmable controller 6, programmable controller 6 one ends are connected with computer 5, and the counter X0 of programmable controller 6, X1 end or X3, X4 end are connected with A, the B end that encoder 1 is adjusted in gap.

Described programmable controller 6 is the FX-2NPLC of Mitsubishi, and counter used is 2 phase 2 high-speed counters.

Due to the utility model by gap being adjusted to the test that encoder does not affect the original system position, and use programmable controller and computer to be monitored, standby calender gap adjustment motor and encoder need not be removed, can utilize the program of data detection signal encoder to be carried out to the detection of data, do not affect the normal running operation of standby calender fully, guarantee that gap adjusts motor performance and detect use and the workload that reduces to greatest extent material under prerequisite accurately, and then detect more quickly the quality of encoder, make standby calender reach as early as possible the standard of using on the machine, reduce because encoder is adjusted in the guest machine gap and damage and can not normally go up machine, thereby incur loss through delay the hidden danger of automatically sheet thickness being adjusted, guarantee the in good condition of standby calender and the continuity of producing, stability.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further details.

Referring to Fig. 2, the detection system of encoder performance is adjusted in a kind of calender gap, comprise programmable controller 6, programmable controller 6 one ends are connected with computer 5, and the counter X0 of programmable controller 6, X1 end or X3, X4 end are connected with A, the B end that encoder 1 is adjusted in gap.Programmable controller 6 is the FX-2NPLC of Mitsubishi, and counter used is 2 phase 2 high-speed counters, can adjust encoders 1 to two gaps simultaneously and be detected.

Referring to accompanying drawing 1,2, operation principle of the present utility model is:

Gap being adjusted to the terminal of encoder 1 receives on the respective terminal of programmable controller 6, computer 5 is connected with the programmable controller 6 carefully connected the wire, manually motor 2 one circle or several circles are adjusted in the forward or reverse gap, high-speed counter carries out step-by-step counting, observe corresponding data variation in computer 5, if code-disc rotates a circle, show that data are 128, illustrate that encoder 1 data are adjusted in gap accurate, functional, without replacing; If countless certificates or show that data are inaccurate, differ too large, illustrate that this gap adjusts encoder 1 and damaged, need to change.

Referring to Fig. 3, be illustrated as the FX-2NPLC of Mitsubishi, its 2 mutually 2 high-speed counters be C251, C252, C253, C254, C236, when A, the B that adjusts encoder 1 when gap terminates at X0, X1, counter C251, C252, C254 are effective; When A, the B of gap adjustment encoder 1 terminate at X3, X4, counter C253, C236 are effective.X2 and X5 are unloaded.
