Abstract

Tidsstyring av arbeidsprosedyren for en kontinuerlig oppvaskmaskin betyr en energibesparelse takket være en deling av prosedyren i behandlingsdeler som kun varer så lenge som vaskegodset behandles. Behandingsdelen styres av tldsur forsynt med styrekretser og O-stillings-kretser for justering av operasjonstiden, eliminering. av forstyrrelser bevirket av avbrudd, O-stilling ved innmatning av vaskegodset etc.Time management of the work procedure for a continuous dishwasher means an energy saving thanks to a division of the procedure into processing parts that only last as long as the laundry is processed. The treatment part is controlled by tldsur equipped with control circuits and O-position circuits for adjustment of the operation time, elimination. of disturbances caused by interruptions, O position when feeding the laundry etc.

Description

Kontinuerlig oppvaskmaskin Continuous dishwasher

Den foreliggende oppfinnelse vedrører et tidsstyringssystem for arbeidsprosessen til en kontinuerlig oppvaskmaskin -Jed hjelp av hvilket en vesentlig energibesparelse kan oppnås. The present invention relates to a time management system for the work process of a continuous dishwasher -Jed with the help of which a significant energy saving can be achieved.

(Oppvaskmaskiner av tunneltypen har en transportør som fører "\jaskegodset gjennom et flertall soner- i maskinens langscående retning. Det er tidligere kjent å anvende anordninger ved tiransportøren for å starte og/eller stoppe maskinens drift ^ed tidspunkter hvor godset settes inn i eller tas ut av maskinen.

maskinen, hvilket betyr energitap. Ved hjelp av en mer nøy-aktig styring av arbeidsprosessen er det mulig å eliminere silike ulemper ved maskinen. the machine, which means energy loss. With the help of a more precise control of the work process, it is possible to eliminate such disadvantages of the machine.

Vied oppfinnelsen løses problemet med å drive maskinen i vel-definerte intervaller uten påvirkning av forstyrrelser :. form av f.eks. åpning av dører, en stopp av transportøren eI tc. Ved en innmatning " av godset vil et avfølingsorgan yiedmaskinens innmatningsende starte et elektronisk tidsur éom kun teller tiden når maskinen opererer og settes til 0 lå snart en annen godsladning kommer inn i innføringsenden., Hvis ikke noe mere gods vil komme, stoppes maskinen etter den forutbestemte tidsperiode.

When the goods are fed in, a sensing device at the machine's feed end will start an electronic timer that only counts the time when the machine is operating and is set to 0 as soon as another load of goods enters the feed end. If no more goods will arrive, the machine is stopped after the predetermined period of time. In reality, several of the zones in the machine are controlled in a period of time by means of their own timer, which reduces energy use to precisely the zone where presence

I en kontinuerlig oppvaskmaskin finnes en transportør 10 for å transportere vaskegods på stativer stort sett horisontalt gjfjennom maskinen. Ved innføringsenden begynner en forvask-sone 11 som har en tank 12 i bunnen og et sirkulasjonssystem! o1y3e. rEskt udadvslvøæp sk1e 4 efør rets ilbvoeriteb. rDaegn t ni edstee nne sonseonn en er gvjeansknoem midhdveill-ket In a continuous dishwasher, there is a conveyor 10 for transporting laundry on racks mostly horizontally across the machine. At the feed end begins a pre-wash zone 11 which has a tank 12 at the bottom and a circulation system! o1y3e. rEskt udavslvøæp sk1e 4 efor rets ilbvoeriteb. rDaegn t ni edstee nne sonseonn en is Gvjeansknoem midhdveill-ket

vaskesonen 15 som har en separat tank 16 og et sirkulasjonssystem 17. Det neste trinnet er ettervaskingssonen 18 med en tank 19 som har et avløp 20 for overskuddsvæske som føres til forvasksonen. Tanken 19 er en samletank for rensevæske fra ayslutningssonen 21 som er sluttrengjøringen. Sprøytings-systemet 22 i denne sonen mates direkte via en oppvarmer 23 direkte fra vannledningsnettet og rengjør så godset med rent varmt vann. Dette er anvendbart for en tre-tanksmaskinutfør-else. Dette kan også utføres som en to-tanksutførelse, hvilket betyr at vaskemiddel-vaskesonen og ettervasksonen sljås sammen. Etterat et stativ har forlatt sluttrensingen, føres det hensiktsmessig til en valsetransportør hvor vaskegodjset er selvtørkende. the washing zone 15 which has a separate tank 16 and a circulation system 17. The next step is the post-washing zone 18 with a tank 19 which has a drain 20 for excess liquid which is led to the pre-washing zone. The tank 19 is a collection tank for cleaning liquid from the ice exclusion zone 21 which is the final cleaning. The spraying system 22 in this zone is fed directly via a heater 23 directly from the water mains and then cleans the goods with clean hot water. This is applicable for a three-tank machine version. This can also be carried out as a two-tank design, which means that the detergent-washing zone and the after-washing zone are combined. After a rack has left the final cleaning, it is conveniently taken to a roller conveyor where the laundry is self-drying.

I den hensikt å styre arbeidsprosedyren i maskinen, anvendes; et elektronisk tidsur ifølge koblingsdiagrammet i fig. 2. Tiidsuret har i prinsippet følgende arbeidsmåte: En bryter 24 ved maskinens inngang danner en kontakt når deri påvirkes av et stativ som settes inn i maskinen og mater etj startsignal på en ledning 25 til inngangen hos en invertjerer 26 (en Schmitt trigger) som leder det inverterte og i en virkelig pulsform omdannede signal til en teller 27 som i dette eksempel er en standard modul MC 14541 ifølge vanlig TTL-teknikk. Egenskapene ved denne teller er viktige vec at tellehastigheten (pulsfrekvensen) styres utenfra ved hjelp av en justerbar styrekrets 28 og at telleren ved avbrudd i styringen stopper ved et oppnådd tall og fortsetter derfra ved fornyet starting etter avbruddet. Utgangen 29 fra tejlle::- en mater et signal under den tid tellingen forløper inntjil ejt forutbestemt tall,og signalet opphører da. Under telllingen forsterkes signalet ved hjelp av en transistor 30 som mater 'ein styrestrøm til et relé 31 som styrer en relékontakt 32 In order to control the working procedure in the machine, are used; an electronic time clock according to the connection diagram in fig. 2. In principle, the timer has the following working method: A switch 24 at the input of the machine forms a contact when it is acted upon by a stand which is inserted into the machine and feeds etj a start signal on a wire 25 to the input of an inverter 26 (a Schmitt trigger) which leads the inverted and in a real pulse form converted signal to a counter 27 which in this example is a standard module MC 14541 according to usual TTL technology. The properties of this counter are important in that the counting speed (pulse frequency) is controlled from the outside by means of an adjustable control circuit 28 and that the counter, in the event of an interruption in the control, stops at a reached number and continues from there when restarted after the interruption. The output 29 from tejlle::- en feeds a signal during the time the count proceeds until a predetermined number, and the signal then ceases. During the counting, the signal is amplified using a transistor 30 which feeds a control current to a relay 31 which controls a relay contact 32

spm bevirker transportørens start og innkobler drivkretsjene (<j>ikke vist) for de første sonene 11, 15 og eventuelt 18 hos oppvaskmaskinen. Ettersom pulsfrekvensen er justerbar (her v,ed hjelp av et potensiometer 33 i styrekretsen) , kan peri-oden for drift av maskinen synkroniseres med transporthajstic - heten for stativet, slik at driften opphører i det øyebl|ikk spm stativet forlater den siste sonen for den del av prosedyren som styres av tidsuret. spm causes the conveyor to start and switches on the drive circuits (<j>not shown) for the first zones 11, 15 and possibly 18 of the dishwasher. As the pulse frequency is adjustable (here with the help of a potentiometer 33 in the control circuit), the period of operation of the machine can be synchronized with the transport speed of the stand, so that operation ceases at the moment when the stand leaves the last zone for the part of the procedure controlled by the timer.

Virkningen av denne kortslutning vil være ajt telleren■stopper på det tall den hadde nådd og releet slip-per slik at drivkretsen brytes og godset stoppes.

Under avbruddet blir ingen del avi I prosedyren utelukket ettersom stativet og sprøytingssystlem-et står stille inntil driften gjenopptas. contacts are closed, a 0 signal is obtained at the inverter output 35 to which a number of diodes 36 are connected. These diodes will then short-circuit the control signals to the transistor and the counter. The effect of this short circuit will be that the counter stops at the number it had reached and the relay releases so that the drive circuit is broken and the goods are stopped. When the safety contact is opened again, the control signal is re-established, such that the counter continues counting from the number obtained and the procedure continues. During the interruption, no part of the avi I procedure is excluded as the stand and the spraying system are stationary until operation is resumed.

Thus, a different program will start every time a rack is inserted regardless of the fact that there are, or are not, racks already in the machine.

Energibesparelsen som nevnt innledningsvis fremkommer v^ åThe energy saving as mentioned at the beginning appears v^ å

i delingen av prosedyren i flere soner, hvorved sprøytingsisys--ternet i den respektive sonen arbeider kun når vaskegodsejt behandles i sonen. Ettersom energitapene inneholder frigjitt fuktighet og varme ledet til en ventilasjonsanordning plassert på maskinen, reduseres disse tap når flere soner i in the division of the procedure into several zones, whereby the spraying system in the respective zone only works when the laundry is processed in the zone. As the energy losses contain released moisture and heat led to a ventilation device located on the machine, these losses are reduced when several zones in

maskinen anvendes kun i korte intervaller. En annen fordel ved denne deling av prosedyren fremkommer ved et lavere lydnivå takket være det faktum at lydkildene er færre. the machine is only used in short intervals. Another advantage of this division of the procedure results in a lower sound level thanks to the fact that the sound sources are fewer.
