Description

Den foreliggende oppfinnelse vedrører prinsipp og utforming av et energisparende spjeld til anbringelse i • sugerøret ved pneumatiske transportanlegg. The present invention relates to the principle and design of an energy-saving damper for placement in • the suction pipe of pneumatic transport systems.

Spjeld anvendes i nesten alle pneumatiske transportanlegg til avsperring av den enkelte sugestuss, når denne ikke er i bruk. Spjeldet er manuelt betjent og omstilles normalt kun når maskinen omstilles. Det vil være forbundet med stort besvær å omstille spjeldene under drift. Dampers are used in almost all pneumatic transport systems to shut off the individual suction nozzle when it is not in use. The damper is manually operated and is normally only adjusted when the machine is adjusted. It will be associated with great difficulty to readjust the dampers during operation.

Det energisparende spjelds prinsipp og utforming er ifølge oppfinnelsenkarakterisert vedat det anbringes sentralt i avsugningen fra den enkelte maskin- at det ikke lukker sugerøret helt, da røret ved total lukning, vil klappe sammen, og at det er automatisk styrt av emnene, umiddelbart før.disse passerer inn i maskinen. The principle and design of the energy-saving damper is, according to the invention, characterized by the fact that it is placed centrally in the suction from the individual machine - that it does not close the suction pipe completely, as the pipe will collapse when it is completely closed, and that it is automatically controlled by the workpieces, immediately before these passes into the machine.

Energisparespjeldet betjenes av luftsylindre som styres gjennom en styringsenhet. Ved maskinens inngangsside anbringes en styrekontakt som påvirkes av de innløpende emner. Blir kontakten ikke påvirket innenfor små innstillbare tids-intervaller, vil automatikken lukke energisparespjeldet. Så snart styrekontakten igjen påvirkes av et emne/vil automatikken åpne spjeldet momentant. The energy-saving damper is operated by air cylinders which are controlled through a control unit. At the machine's entrance side, a control contact is placed which is affected by the incoming workpieces. If the contact is not affected within small adjustable time intervals, the automatic system will close the energy-saving damper. As soon as the control contact is again affected by an object, the automatic system will open the damper momentarily.

Ved anvendelse av dette prinsipp oppnås at luftmengden gjennom transportanlegget nedsettes betydelig - selv under korte stillstandsperioder. Da luften i arbeidslokalet som regel er oppvarmet, vil det kunne spares varme. Utover dette vil reduksjonen av luftmengden gjennom transportanleggets suger, nedsette kraftforbruket på sugemotoren. Endelig vil den nedsatte luftmengde gi en kapasitetsforøkning på eventuelt filteranlegg. By applying this principle, it is achieved that the amount of air through the transport system is significantly reduced - even during short standstill periods. As the air in the workplace is usually heated, it will be possible to save heat. In addition to this, the reduction of the amount of air through the transport system's suction will reduce the power consumption of the suction motor. Finally, the reduced amount of air will increase the capacity of any filter system.

Den beste- og billigste utførelsesform for et energisparespjeld er ifølge oppfinnelsen anvendelsen av et knivspjeld, idet dette i praksis har vist seg å være det mest driftssikre, og samtidig det spjeld som har en god selvrensende effekt. Energisparespjeldet kan dog ifølge oppfinnelsens prinsipp ut-formes både som skyve-, vippe- og dreiespjeld. According to the invention, the best and cheapest embodiment of an energy-saving damper is the use of a blade damper, as this has in practice been shown to be the most reliable, and at the same time the damper which has a good self-cleaning effect. However, according to the principle of the invention, the energy-saving damper can be designed both as a sliding, tilting and rotary damper.

De karakteristiske trekk ved oppfinnelsen vil for-øvrig fremgå av de etterfølgende krav samt av den etterfølgende beskrivelse méd henvisning til et i tegningen vist'-utførelses--eksempel, hvor The characteristic features of the invention will also be apparent from the subsequent claims as well as from the subsequent description with reference to an embodiment shown in the drawing, where

fig. 1 viser et knivspjeld med komponentene trukket ut fra hverandre, og fig. 1 shows a blade damper with the components pulled apart, and

fig. 2 viser prinsippet for knivspjeldet i åpen og i lukket utførelse. fig. 2 shows the principle of the blade damper in open and closed design.

Knivspjeldet består, som vist i fig. 1^av eri:spjeld-plate A, som skyves inn mellom tilkoplingsstussene B og C. Spalten, hvori sp jeldplaten. skal gli, dannes mellom B og C ved hjelp av skinnene D, som samtidig danner sidestyring for spjeldplaten. I holderne G anbringes luftsylindrene E og endene av stempelstengene fastgjøres i hullene i den opp-bukkede kant på spjeldplaten.. t Styreenheten F er skjematisk vist og bygges opp av nødvendige standardkomponenter, som kan utføre oppfinnelsens prinsipielle funksjoner. The blade damper consists, as shown in fig. 1^of eri:slider plate A, which is pushed in between the connecting pieces B and C. The gap, in which the damper plate. should slide, is formed between B and C by means of the rails D, which at the same time form lateral guidance for the damper plate. The air cylinders E are placed in the holders G and the ends of the piston rods are fixed in the holes in the bent-up edge of the damper plate.

Prinsippskissen fig. 2 viser knivspjeldet i lukket utførelse A og åpen utførelse B. i The principle sketch fig. 2 shows the blade damper in closed design A and open design B. i

I den viste utførelsesform er energispareprinsippet anvendt på et skyvespjeld, men det er intet til hinder for å anvende andre former spjeld for å utøve oppfinnelsens prinsipp. In the embodiment shown, the energy-saving principle is applied to a sliding damper, but there is nothing to prevent using other forms of damper to implement the principle of the invention.

Energisparespjeldet vil utelukkende finne anvendelse innenfor trebearbeidende industri, hvor pneumatiske transportanlegg suger bort spon og støv fra den enkelte trebearbeidings-maskin. The energy-saving damper will exclusively find use within the woodworking industry, where pneumatic transport systems suck away shavings and dust from the individual woodworking machine.

På den enkelte bearbeidingsmaskin kan det være montert flere verktøy. Hvert av disse krever en avsugningsstuss med tilhørende rør, som samles sammen med rørene fra de øvrige verktøyer, i et sentralrør. Sentralrøret forbindes med suge-siden på en sentrifugalventilator og utblåsningssiden forbindes med et filteranlegg eller en syklon. Several tools can be mounted on the individual processing machine. Each of these requires a suction nozzle with associated pipes, which are collected together with the pipes from the other tools in a central pipe. The central pipe is connected to the suction side of a centrifugal ventilator and the discharge side is connected to a filter system or a cyclone.

Under de i dag eksisterende driftsforhold, vil avsugningen være konstant åpen, selv om utnyttelsen av bearbeid-ningsmaskinen for eksempel kun er 40% fordelt over hele arbeidsperioden. Under the operating conditions existing today, the extraction will be constantly open, even if the utilization of the processing machine, for example, is only 40% distributed over the entire working period.

Ved å anbringe et energisparespjeld i sentralrøret vil luftmengden gjennom anlegget i de resterende 60% av drifts- tiden bli redusert med 75% og. el.kraftforbruket med 50%. By placing an energy-saving damper in the central pipe, the amount of air through the system in the remaining 60% of the operating time will be reduced by 75% and. electricity consumption by 50%.
