Description
Vynález sa týká spísobu a zariadenia na kontrolu kvality výrobkov s otvorom pri vstrekovaní, hlavně kontrolu spoja, ktorý sa vytvoří na opačnéj straně od směru toku taveniny, pri spčsobe vstrekovania, pri ktorom jě směr toku taveniny nerovnobežný s osou otvoru.BACKGROUND OF THE INVENTION The present invention relates to a method and apparatus for controlling the quality of articles having an injection opening, in particular to control a joint that is formed on the opposite side of the melt flow direction in an injection method in which the melt flow direction is not parallel to the hole axis.
Doteraz medzi najpoužívanejšie spdsoby kontroly kvality výstreku s otvorom patria skúšky vizuálně a laboratorně. Vizuélna kontrola výstreku, ktorá následuje po otvorení formy a Vybraní výstreku,je sice operatívna, ale z hradiska posúdenia kvality výrobku velmi orientačná, hlavně u výrobkov s predpísanými fyzikélno-mečhanickými vlastnosťami, pričom na samotné vizúélne posúdenie vplýva 1’udský faktor a samotné posúdenie je zaťažené jeho chybou. Tiež vizuálna kontrola vyžaduje přítomnost obsluhy a tým ekonomicky znevýhodňuje případný plnoautomatický chod zariadenia.To date, the most commonly used methods of controlling the quality of a spray with an orifice include the visual and laboratory tests. The visual inspection of the spray, which follows the opening of the mold and the removal of the spray, is operative, but is very indicative of the quality assessment of the product, especially for products with prescribed physico-methanoic properties. burdened by his error. Also, visual inspection requires the presence of the operator and thus economically disadvantages the possible fully automatic operation of the device.
Ďalšie skúšky kvality výstreku sú laboratórneho charakteru. Existuje celý súbor laboratórnych skúšok od menej přesných až po najpresnejšie, ktoré dávajú dokonalý obraz o kvalitě výstreku. Tieto laboratorně skúšky, ktoré sa nedajú úplné vylúčiť i při spósobe kontroly kvality podTa vynálezu, majú veTkú nevýhodu v ich časovej náročnosti. Od zhotovenia výrobku po vykonanie a vyhodnotenie skúšok uplynie značné časové obdobie napr. niekoTko dní, čo ačže zapříčinit počas tohto obdobia výrobu zmatkov a tým vel’ké ekonomické straty vo výrobě.Other spray quality tests are of a laboratory nature. There is a whole set of laboratory tests from less accurate to the most accurate, which give a perfect picture of the quality of the spray. These laboratory tests, which cannot be completely eliminated even with the method of quality control according to the invention, have a great disadvantage in their time-consuming nature. A significant period of time elapses from the production of the product to the execution and evaluation of the tests, e.g. several days, although this will cause confusion during this period and thus great economic losses in production.
Uvedené nedostatky odstraňuje spdsob a zariadenie na kontrolu kvality výrobkov s otvorom, při vstrekovaní, s osou otvoru nerovnobežnou so smerom toku taveniny, ktorý sa vyznačuje tým, že v okolí miesta opatovného spojenia rozděleného toku taveniny sa snímá teplota taveniny a/alebo tlak taveniny, hodnoty ktorých sa privádzajú do vyhodnocovacíeho zariadenia, pričom slúžia ako vstupné informacie pre matematický model, popísaný jedno- až viacparametrovou funkciou a vyhodnocovacie zariadenie po vyhodnotení vstupných informácií vyšle signál o kvalitě výrobku.The above-mentioned deficiencies are eliminated by a method and apparatus for controlling the quality of products having an orifice, on injection, with an orifice axis not parallel to the direction of the melt flow, characterized in that the melt temperature and / or melt pressure They are used as input information for the mathematical model described by one- to multi-parameter function and after evaluation of input information the evaluation device sends a product quality signal.
Zariadenie na kontrolu kvality výrobkov podía tohto vynálezu je riešené tak, že snímač teploty taveniny je súčasťou tlaSnáho kolika, ktorý je prevodníkom tlaku taveniny na snímač sily, pričom elektrický výstup snímača teploty taveniny je s vyhodnocovacím zariadením spojený pomooou vodičov, ktorá sú vedené otvorom v tlačnom kolíku.The product quality control device according to the invention is designed such that the melt temperature sensor is part of a pressure pin which is a converter of the melt pressure to the force sensor, wherein the electrical output of the melt temperature sensor is connected to the evaluation device by means of conductors. pin.
Tento spčsob kontroly kvality výrobkov je výhodné použit na kontrolu fyzikálno-mechanlckých vlastností, pretože existuje pře každý tvarovo rčzny druh výrobku a rčzny druh materiálu mlnimálna hodnota tlaku a teploty taveniny, pri ktorej má výrobok v mieste spojenia rozdělených tokov určité minimálně požadované fyzikálno-mechanické vlastnosti.This method of quality control of products is advantageously used to control the physico-mechanical properties, since there is a minimum pressure and melt temperature value for each shape and material type at which the product has some minimally required physico-mechanical properties at the junction of the split streams. .
Výhodou spísobu kontroly kvality výrobkov podía vynálezu je hlavně okamžitá informácia o kvalitě výrobku. Tým sa zaručí kvalitně výroba i pri automatickou cykle bez přítomnosti obsluhy, odstráni sa výroba zmátkov, čím sa zvýčl produktivita a hospodárnosti výroby.The advantage of the product quality control method according to the invention is mainly immediate information about product quality. This ensures high-quality production even in an automatic operator-free cycle, eliminating confusion, increasing productivity and economy of production.
fiallie výhody a význaky spčsobu kontroly kvality výrobkov podía vynálezu sú zahrnuté v nasledujúcom popise příkladného prevedenia, ktoré je schematicky znázorněné na priloženom výkrese.Further advantages and features of the method of quality control of products according to the invention are included in the following description of an exemplary embodiment, which is schematically shown in the attached drawing.
V miesta opětovného spojenia rozděleného toku taveniny je umiestnený tlačný kolík £, ktorý jedným koncom zasahuje do dutiny formy 8 a slúži ako převodník tlaku taveniny na silu, ktorú prenáéa na snímač 2 sily, ktorého elektrický výstup je spojený s vyhodnocovacím zarladením J. Na konci tlačného kolíka £, ktorý zasahuje do dutiny formy 8,je umiestnený snímač £ teploty taveniny. Spojenie měrného miesta snímača £ teploty taveniny s vyhodnocovacím zarladením J je vykonané vodičmi £, ktoré prechédzajd v/taním v ose tlačného kolíka £.At the point of reconnection of the split melt flow, a pressure pin 6 is provided, which extends into one of the cavities of the mold 8 at one end and serves as a transducer of the melt pressure to the force transmitted to the force sensor 2. A pin 6 which extends into the mold cavity 8 is provided with a melt temperature sensor 6. The connection of the measurement point of the melt temperature sensor 6 to the evaluation device J is carried out by conductors 6 which pass in / out in the axis of the push pin 6.
Pri plnění formy £ taveninou, ktoré vstupuje vtokom £ do dutiny formy 8, sa prúd taveniny rozdělí na dva toky, ktoré obtekajú třň £. Na odvrátenej straně od vtoku £ príde k opatovnému spojeniu rozdělených tokov. V mieste spojenia rozdělených tokov vzniká spoj, ktorého kvalita v značnej miere určuje vlastnosti^výrobku. Kontrola kvality spoja sa vykoná tak, že v mieste spojenia je umiestnený snímač £ teploty taveniny a tlačný kolík £ snímača tlaku taveniny, ktoré zaznamenajú hodnotu teploty a tlaku taveniny v okamihu spojenia tokov.When the mold 6 is filled with melt, which enters the inlet 6 into the mold cavity 8, the melt stream is divided into two streams which bypass the mandrel. On the far side from the inlet 6, the split streams will be joined again. At the point of joining the split streams, a joint is formed whose quality largely determines the properties of the product. The quality control of the joint is carried out by placing a melt temperature sensor 6 and a melt pressure sensor pin 6 at the connection point, which record the temperature and melt pressure values at the time of the flow connection.
Počiatočná hodnota teploty a tlaku taveniny sa přivede do vyhodnocovacíeho zariadenia J, kde slúži ako vstupný údaj pre vyhodnotenie kvality podía predom stanoveného matematického modelu, ktorý je popísaný v najjednoduchéom případe jednoparametrovou funkciou, to je napr. tlaku alebo teploty taveniny, připadne vlacparametrovou funkciou, ako tlaku a teploty taveniny, rýchlosti vstrekovania, teploty formy a pod. Podía zložitosti matematického modelu je použité 1 vyhodnocovacíe zariadenie J, to je napr. jednoduché elektronické zariadenie až mikroprocesor. Po vyhodnotení vstupných údajov vyhodnocovacíe zariadenie £ vyšle informáciu o kvalitě vytvořeného spoja ako i kvalitě výrobku.The initial value of the temperature and melt pressure is fed to an evaluation device J, where it serves as an input for the quality evaluation according to a predetermined mathematical model, which is described in the simplest case by a single parameter function, e.g. melt pressure or temperature, optionally by a function of the parameters such as melt pressure and temperature, injection rate, mold temperature and the like. According to the complexity of the mathematical model, 1 evaluation device J is used, e.g. simple electronic device to microprocessor. After evaluating the input data, the evaluation device 6 sends information on the quality of the formed joint as well as the quality of the product.
