Abstract
The invention relates to a storage and parameter transfer combined pressing method; and after pressing equipment is stopped for a long time, the equipment automatically adopts a set of pressing parameters with slow pressing speed and long exhaust time to press so as to guarantee the blank yield after the reduction of powder water content. Once powder with abnormal water content is used up, when the powder with normal water content is adopted to press, the equipment can use back the set of parameters with normal speed for pressing. Meanwhile, when the equipment normally operates, operators can modify a batch of exploratory parameter combinations; and the batch of exploratory parameters dose not influence the formal parameter combination used by the equipment before being transmitted. After the batch of exploratory parameters are modified, the operators once use the whole batch of exploratory parameters for covering the used parameters for pressing through a controller, and back up the original formal parameter combination.
Description
Technical field
The present invention relates to a kind of by the drawing method, particularly a kind of drawing method for pressed powder machine that store and call parameters combines.
Background technology
In the production of general ceramic wall and floor bricks, break down shutdown or production line stop be inevitable.Between down period, it is moisture content that the powder stayed in feed bin, filler device holds labile most.Because environment temperature is high, after moisture evaporation, the moisture content of powder reduces, and also causes powder to be difficult to bonding when being pressed.Therefore in the process of again suppressing after equipment is shut down for a long time, the base substrate that the powder that moisture content changes suppresses, its yield rate is extremely low.Because of high cost, the powder that moisture content changes usually does not return powder workshop and carries out proportioning.Therefore to the powder that these moisture content change, its processing method is mainly by pressing process, and pressing speed reduced, the methods such as evacuation time growth solve.The object that evacuation time increases is the air in powder is discharged more fully, avoids making powder be bonded into base substrate between downtrodden powder due to trapped air.Slowing down pressing speed, is then allow powder after moisture content changes, and the adhesive power of powder can be set up at a slow speed equably, thus improves the yield rate of base substrate.But once the powder that moisture content changes runs out, then need not re-use the mode suppressing and increase evacuation time slowly and carry out.Because moisture content is normal, originally formal parameter can be used back.
Therefore be necessary to provide a kind of method to operator, the method is after press device is shut down for a long time, and equipment adopts one group of pressing speed slow automatically, and the pressing parameter that evacuation time is long is suppressed, to ensure that powder moisture content reduces the yield rate of rear base substrate.And once after the powder of moisture content exception runs out, when adopting the normal powder pressing of moisture content, equipment should be able to go back to and use that group parameter of normal speed to suppress.
In addition, base substrate is very harsh to the requirement of productivity ratio, requires that the time of each production link may be short.For example in compacting link, if the production action that 200ms can complete, 210ms must not be allowed to complete.Therefore after powder pressing stable molding, operating personnel are all boosted productivity by the mode consuming time attempting constantly shortening each production action.
In all compacting actions, exhaust event and compacting action are most holding times, are also have the action link shortening potentiality most simultaneously.Operator affects the parameter of evacuation time and press time by changing, shorten exhaust used time and compacting used time.But because the yield rate of base substrate is very responsive with compacting action to exhaust event, when evacuation time and press time are significantly shortened, although compacting frequency gets a promotion, the yield rate of product also there will be downslide.Therefore operator usually all can only on impact exhaust, the press time parameter make little step-length amendment after, observe these parameters and whether negative effect is existed to the yield rate of base substrate, as no, then adopt these parameters to suppress, or shorten the exhaust used time further to pursue higher productivity ratio.
This mode of operation brings very big inconvenience to operator, because impact exhaust, the press time controls by multiple parameters combination, more often, whether operator must have feasibility to the whole parameters combination parameters combination set by could judging of modifying.Thus, require that operator completes the amendment of multiple parameter at short notice, with observing effect.The large more options of this act of revision are carried out between do action.For example, how suppressing frequency is 10 times/min, and namely press device 6s completes and once suppresses circulation.So operator will to the amendment that exhaust or pressing parameter are combined in 6s.Or stopped by equipment, after changing needing the carrying out of revising parameter, starting device again, the parameter after allowing equipment use change is suppressed.As amended parameter does not make base substrate yield rate and productivity ratio reach the effect of expectation, then need again to shut down amendment parameter, till debugging out suitable parameter.
Therefore be necessary to provide a kind of method to operator, the method is when equipment normally runs, and operator can modify to the parameters combination of a collection of exploration, and this batch of exploratory parameter be not by formal parameters combination that the equipment that do not affect before transmitting is using.After this batch of exploratory parameter modification, former formal parameters combination by controller will exploratory parameter be disposable is by the gross covered to suppressing in parameter, and backs up by operator.After the compacting circulation that exploratory parameters combination controls for several times, operator judges whether exploratory parameter has positive effect to productivity ratio and yield rate, determines whether use exploratory parameters combination to suppress as formal parameter thus.

In order to understand better and implement, describe the present invention in detail below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is the workflow diagram of controller of the present invention.
Detailed description of the invention
Refer to Fig. 1, it is the workflow diagram of controller of the present invention.The storage of a kind of parameters combination of the present invention and call method, receive the time signal of timer to control the work of press device by controller; Meanwhile, by memory, input parameter stored and shown by display.Be the workflow diagram of controller of the present invention below:
S1: when equipment adopts formal parameter to suppress, the ruuning situation of controller to equipment judges; If run into shutdown situation, perform step S15; If not, then step S2 is performed.
S2: this controller determines whether to explore parameters combination compacting pattern; If not, then undo; If so, then step S3 is performed.
S3: whether this controller judges to explore parameters combination complete; If all exploration parameters are all by complete setting, then perform step S4; If it is imperfect to explore parameters combination, then perform step S5; Exploration parameters combination is stored in database by controller, in order to calling in the future.
S4: exploration parameters combination is stored to database; And perform step S6.
S5: control display prompts operator and carry out exploration optimum configurations, and perform step S3.
S6: formal parameters combination is stored in database, more complete parameters distribution will be set to provisional parameter combination, and perform step S7.
In this step, the combination of this provisional parameter is the combination with action parameter and life parameters framework.Not transmitted and not covering provisional parameter combination, be stored in database by formal parameters combination, storing formal parameters combination is that controller can call former formal parameter fast in database in order at the end of provisional parameter combination life.
S7: judge whether to use provisional parameter combination to suppress; In this way, step S8 is performed; As no, then redirect S14.
This step is except playing inquiry effect, and also playing provisional parameter arranging period does not affect the effect that formal parameters combination carries out suppressing.
S8: control appliance uses provisional parameter combination to carry out automatic cycle compacting, and performs step S9;
S9: controller judges whether to receive the instruction stopping using provisional parameter to combine compacting; If so, then step S14 is performed; If do not receive termination to suppress instruction temporarily, perform step S10.
The object of this step be allow operator can stop at any time use provisional parameter combination, and make controller can go back to fast use formal parameters combination carry out equipment compacting.
S10: judge whether the current provisional parameter combination used belongs to exploration parameters combination.If do not belonged to exploration parameters combination, perform step S11; If belong to exploration parameters combination, then perform step 12.
S11: the life calling the provisional parameter combination in memory limits number of times, and judges the life cycle of provisional parameter, if it is 0 that the life of provisional parameter limits number of times, then performs step S14; If it is not 0 that the life of provisional parameter limits number of times, then this life is limited number of times and reduce once, and perform step S8.
The life parameters that the life cycle of the provisional parameter in this step is combined by provisional parameter determines, the automatic cycle compacting that the action parameter often completing a provisional parameter combination carries out, provisional parameter is labeled and used 1 time.When the life parameters of provisional parameter is decremented to 0, the life of provisional parameter terminates.
S12: judge whether to receive the confirmation and explore the feasible signal of parameters combination; In this way, then step S13 is performed; As no, then perform step S11.
This step can allow the pressing result of exploratory parameter in operator's complete observation life parameters number of times, can be directly just also formal parameter exploration Parameter Switch before life parameters does not exhaust.
S13: provisional parameter is covered to formal parameters combination, and performs step S14.
S14: controller reads formal parameters combination from database, stops using provisional parameter to combine and suppresses and use formal parameters combination to suppress, method ends.
S15: when equipment downtime being detected, controls timer and starts timing; When equipment is activated into automatic cycle compacting again, downtime, timer stopped timing, redirect S16.
This step, mainly in order to obtain shutdown duration, being shut down duration and being used for judging whether to belong to long-time shutdown in S16, judging whether the moisture content of powder changes with this.
S16: judge that whether shut down duration has exceeded permission standard downtime, if do not exceeded, performs step S14; If exceed, perform step S17.
In this step; permission standard downtime is the time parameter that the producer is arranged according to knowhow; the numerical value of parameter is relevant with powder moisture evaporation rate; operator rule of thumb determines that certain powder is after shutdown duration exceedes certain time limit; whether powder moisture content changes, and as changed, this time limit is set to standard downtime.
S17: judge whether to adopt slow pressure mode; If so, then step S18 is performed; If not, then adopt normal mode compacting powder, then perform step S14;
In this step, long-time pressing mode of shutting down rear equipment is selected to be preset by operator.Have slow pressure mode and normal pressing mode optional, slow pressure mode is that pressing speed is slow, the pressing mode that evacuation time is long, and the parameters combination of its correspondence is slow pressure parameters combination.The formal parameters combination that normal parameter combination uses before being and shutting down.This step object is, all very large owing to not being each powder its water-cut variation after long-time shutdown, if water-cut variation is little, then there is no need to reduce productivity ratio and adopts slow pressure mode to suppress, directly use normal pressurization mode.
S18: judge whether that use is dispatched from the factory recommendation combination parameter; If so, then step S6 is performed; If not, just suppress for self-defined combination parameter, perform step S19 simultaneously.
In this step, recommendation of dispatching from the factory combination parameter is the parameters combination that device fabrication business pre-enters before equipment dispatches from the factory, and custom parameter combination is the parameters combination that operator determines according to the condition of self experience, equipment characteristic and Workplace.The same with exploration parameters combination, recommendation of dispatching from the factory combination parameter and custom parameter combination also have action parameter and life parameters combination.The object of this step is to ensure inexperienced operator, can use recommendation parameters combination of dispatching from the factory.
S19: controller judges whether custom parameter combination is complete; If all custom parameters are all by complete setting, custom parameter combination is stored in database by controller, in order to calling in the future, and performs step S6; If this custom parameter is imperfect, then perform step S20.
S20: control display prompts operator and carry out exploration optimum configurations, and perform step 19.
Concrete, in above-mentioned steps, described exploration parameters combination refers to the experimental parameters combination that operator formulates for production technology, combined arrangement comprises two parts, a part is the action parameter controlling the actions such as exhaust, compacting, another part explores the spendable number of times of parameters combination, is called life parameters.After equipment adopts the action parameter of exploratory parameters combination to complete once compacting, the life parameters exploring parameters combination is reduced 1 time, and when life parameters is reduced to 0, the life exploring parameters combination terminates, and the formal parameter of equipment Automatically invoked is suppressed.The integrality of parameters combination refers to that exploring all parameters in parameters combination was all set up.
For example, the life of provisional parameter is set to total degree and is restricted to 10 times.So, when the number of times of provisional parameter is decremented to 0 for step-length from 10 with 1, the life of provisional parameter terminates.Provisional parameter life parameters is determined by exploring parameters combination or delaying pressure parameters combination, when being explored parameters combination and covering, provisional parameter combination life parameters equals the life parameters exploring parameters combination, when being covered by slow pressure parameters combination, then equals the life parameters of slow pressure parameters combination.Explore the life parameters of parameters combination, formulated according to the regulation of Workplace by operator, such as Workplace allows experiment percent defective high, then life parameters can be arranged larger, otherwise then smaller.The powder surplus that the life parameters of slow pressure parameters combination is changed according to moisture content by operator is determined, restriction number of times arranges larger by surplus material at most, and restriction number of times arranges smaller by surplus material at least.The object of this step is, no matter be explored parameters combination or the covering of slow pressure parameters combination, provisional parameter combination all can be subject to the restriction of life parameters, and at the end of life parameters, controller automatically proceeds to and uses formal parameters combination to suppress.
The present invention is not limited to above-mentioned embodiment, if do not depart from the spirit and scope of the present invention to various change of the present invention or distortion, if these are changed and distortion belongs within claim of the present invention and equivalent technologies scope, then the present invention is also intended to comprise these changes and distortion.
