Description
Industrivaskemaskin. Industrial washing machine.
Oppfinnelsen vedrører en vaskemaskin beregnet for industrielt bruk, idet den fortrinnsvis er tenkt anvendt for vasking av maskindeler e. 1. Anordningen ifølge oppfinnelsen kan imidlertid med fordel også gis en rekke andre anvendelser hvor deler skal renses eller behandles med spesielle væsker. Således kan vaskemaskinen ifølge oppfinnelsen også benyttes til avfetting, dekarbonisering, stripping, fosfatering, herdebad, etsing, rustbeskyttende bad m. v. Flere maskiner ifølge oppfinnelsen kan likeledes anordnes i serie, slik at industrielle gjenstander kan gjennomgå en trinnvis rense- og/eler behandlingsprosess. The invention relates to a washing machine intended for industrial use, as it is preferably intended to be used for washing machine parts e. 1. However, the device according to the invention can also be advantageously used in a number of other applications where parts are to be cleaned or treated with special liquids. Thus, the washing machine according to the invention can also be used for degreasing, decarbonisation, stripping, phosphating, hardening baths, etching, rust protection baths, etc. Several machines according to the invention can also be arranged in series, so that industrial objects can undergo a step-by-step cleaning and/or treatment process.
Industrivaskemaskinen ifølge oppfinnelsen er enkel og solid i sin konstruksjon og drives med trykkluft, hvilket vanligvis forekommer ved de fleste industrielle an-legg. Den omfatter en oventil åpen vaskevæskebeholder, i hvilken er opp- og ned-bevegelig anordnet en understøttelse for vaskegods, hvilken understøttelse beveges ved hjelp av en stempel-sylinderanordning der fortrinnsvis drives med trykkluft over en automatisk virkende omstillingsventil, for tilveiebringelse av nevnte pulserende bevegelse. The industrial washing machine according to the invention is simple and solid in its construction and is operated with compressed air, which usually occurs in most industrial plants. It comprises a top-vented washing liquid container, in which a support for washing goods is arranged up and down, which support is moved by means of a piston-cylinder device which is preferably operated with compressed air over an automatically acting switching valve, to provide said pulsating movement.
Maskinen ifølge oppfinnelsen kan med fordel også omfatte organ for automatisk styring av tilførsel av vaskegods som beveger seg langs en hensiktsmessig transportbane, slik at porsjoner av vaskegodset suksessivt underkastes behandling i vaskebeholderen og etter utført behandling igjen føres tilbake til transportbanen. I denne kan, om ønskes, inngå to eller flere maskiner ifølge oppfinnelsen hvis godset skal underkastes en trinnvis behandling. The machine according to the invention can advantageously also include a device for automatically controlling the supply of laundry which moves along an appropriate transport lane, so that portions of the laundry are successively subjected to treatment in the washing container and, after the treatment has been carried out, returned to the transport lane. This can, if desired, include two or more machines according to the invention if the goods are to be subjected to step-by-step processing.
Det kjennes fra tidligere industrivas-kemaskiner som omfatter regulerbare automatisk virkende ventilanordninger for trykkluft for bevegelse av vaskegods, slik at dette utsettes for en vertikalt oscille-rende bevegelse eller holdes oppløftet resp. nedsenket i en rensevæske. Videre er det kjent å anordne vaskegodspulver, der ved passende organ styres til. og. fra en industrivaskemaskin, f. eks. ved. rullebaner. It is known from earlier industrial washing machines which include adjustable, automatically acting valve devices for compressed air for movement of laundry, so that this is exposed to a vertically oscillating movement or is held up or immersed in a cleaning liquid. Furthermore, it is known to arrange laundry powder, which is controlled by a suitable organ. and. from an industrial washing machine, e.g. by. runways.
Nærmere bestemt angår oppfinnelsen en industrivaskemaskin omfattende en oventil åpen vaskevæskebeholder, i hvilken er anordnet en vertikalt bevegelig un-derstøttelse for vaskegods, hvilken under-støttelse er festet til den øvre ende av stempelstangen for en vertikalt anbragt stempelsylinderanordning, der drives med trykkmedium over en kontrollerbar automatisk virkende ventilinnretning (for valgfri bevegelse av nevnte understøttelse til oppløftet, nedsenket eller pulserende stilling). More specifically, the invention relates to an industrial washing machine comprising a top-vented washing liquid container, in which a vertically movable support for washing goods is arranged, which support is attached to the upper end of the piston rod for a vertically arranged piston cylinder device, which is operated with pressure medium over a controllable automatically acting valve device (for optional movement of said support to the raised, lowered or pulsating position).
Det nye og karakteristiske for industrivaskemaskinen ifølge oppfinnelsen er at sylinderen er forsynt med en rørforbin-delse, som setter rommet under stempelet i forbindelse med en omstyringssleid, hvis bevegelse styres av fjærarmer som er innstillbart festet på en vertikal spindel, der er forbundet med stempelstangens øvre ende, f. eks. med tverrarmen, idet nevnte omstyringssleid er således anordnet at rø-ret kan settes i forbindelse med en trykk-mediumkilde resp. i forbindelse med fri luft, hvorhos anordningen videre omfatter en manuelt innstillbar betjeningsarm for en flerveisventil for valgfri dirigering av trykkmedium til nevnte sleidventil. The new and characteristic feature of the industrial washing machine according to the invention is that the cylinder is provided with a pipe connection, which puts the space under the piston in connection with a reversing slide, the movement of which is controlled by spring arms which are adjustably attached to a vertical spindle, which is connected to the upper part of the piston rod end, e.g. with the cross arm, the said reversing slide being arranged in such a way that the pipe can be connected to a pressure medium source or in connection with free air, where the device further comprises a manually adjustable operating arm for a multi-way valve for optional routing of pressure medium to said slide valve.
