(54) Indretning til støvsugning af et baneformet materiale.(54) Device for vacuum cleaning a web-shaped material.

Opfindelsen angår en indretning til støvsugning af et baneformet materiale, eksempelvis til en for berøring sart papirbane, ved samtidig blæsning og sugning af luft mod henholdsvis fra materialebanens overflade. Ved industriel behandling af baneformet materiale, eksempelvis ved arkudskærings- og omrulningsmaskiner til papirbaner, frembyder støvdannelse på materialeoverfladen et problem. Produktets kvalitet for-BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a device for vacuuming a web-shaped material, for example to a paper-sensitive web for simultaneous blowing and suction of air towards the surface of the material web, respectively. In industrial processing of web-shaped material, for example by sheet-cutting and rolling machines for paper webs, dust formation on the material surface presents a problem. The quality of the product

retninger. Der har været gennemført forsøg med indretninger til støvsugning af den kontinuert løbende materialebane, men hidtil kendte ind-^ retninger har vist sig at være vanskelige for ikke at sige umulige at ^ bruge ved berøring med sarte, eksempelvis bestrøgne materialebaner, ef tersom disse let på ukontrollabel måde kan suges ind mod afsugningsmund- 2 Π4235 stykket og andre fremspringende dele.directions. Experiments have been conducted with devices for vacuuming the continuous running web, but previously known devices have proved to be difficult not to say impossible to use when touching delicate, e.g. coated webs, if lightly uncontrollable way can be sucked in against the suction mouth piece 2 fr4235 and other projecting parts.

Opfindelsen, som angår en indretning til støvsugning og samtidig fiksering af materialebanen i en for opnåelse af den bedste støvsugningseffekt og mindste risiko for berøring optimal afstand, er ejendommelig ved, at mindst én, tværs over materialebanen forløbende række blæseåbninger, fortrinsvis af øjenlågtypen, er udformet i eller tæt ved et parallelt med, og op til materialebanens overflade beliggende fikseringsplan, hvilke blæseåbninger står i forbindelse med et tilførselsorgan for blæseluft og er udformet på en sådan måde, at de blæser luftstrømme mellem materialebanen og fikseringsplanet i det væsentlige parallelt med materialebanens bevægelsesretning, og at mindst én sugespalte, der står i forbindelse med et organ til bortsugning af luft, er udformet parallelt med rækken eller rækkerne af blæseåbninger. Eftersom den for effektivisering af støvsugningen påblæste luft bringes til at strømme mellem det baneformede materiale og en fikseringsflade, inden luften suges bort gennem sugespalten eller spalterne opnås samtidig med en god støvsugning en effektiv fiksering af det baneformede materiale i en til sugeeffekten afpasset afstand uden risiko for berøring og forstyrrelse af den eventuelt belagte materialeoverflade.The invention, which relates to a device for vacuuming and simultaneously fixing the material web in order to obtain the best vacuuming effect and minimum risk of contact optimum distance, is characterized in that at least one blower opening, preferably of the eyelid type, is arranged across the material web. in or close to a fixing plane parallel to and up to the surface of the material web, which blow openings communicate with a blower air supply means and are designed to blow air flows between the material web and the fixing plane substantially parallel to the direction of movement of the material web, and that at least one suction slot communicating with a means for extracting air is formed parallel to the row or rows of blow openings. Since the air inflated for efficiency of the vacuum suction is caused to flow between the web-shaped material and a fixing surface, before the air is sucked away through the suction gap (s), an efficient fixation of the web-shaped material at a distance adapted to the suction effect is achieved, without the risk of touching and interfering with any coated material surface.

En hensigtsmæssig udførelsesform for indretningen ifølge opfindelsen er ejendommelig ved, at blæseåbninger er udformet således, at . de blæser luftstrømme både i samme retning og i modsat retning som materialebanens bevægelsesretning, og at der er udformet sugespalter foran og bagved rækken eller rækkerne af blæseåbninger set i materialebanens bevægelsesretning. Herved kan fikseringsevnen yderligere sikres.A convenient embodiment of the device according to the invention is characterized in that blow openings are designed so that. they blow air flows both in the same direction and in the opposite direction as the direction of movement of the material web, and that suction slots are formed in front and behind the row or rows of blow openings seen in the direction of movement of the material web. In this way, the fixing ability can be further assured.

Ved en ændret udførelsesform for indretningen ifølge opfindelsen er blæseåbningerne placeret i mindst tre parallelle rækker, og blæseåbningerne i de yderste rækker er udformet således, at de blæser luftstrømme i det væsentlige parallelt med materialebanens bevægelsesretning med henblik på fiksering af materialebanen, medens blæseåbningerne i de øvrige rækker er udformet således, at de blæser luftstrømme ud i andre retninger end førstnævnte luftstrømme for at opnå en forbedring af støvsugningseffekten.In a modified embodiment of the device according to the invention, the blow openings are arranged in at least three parallel rows and the blow openings in the outer rows are designed to blow air flows substantially parallel to the direction of movement of the material web for fixing the material web, while the blow openings in the other rows are designed so as to blow out airflows in directions other than the former airflows to achieve an improvement in the vacuum cleaning effect.

For at opnå en bedre indsugning af støvet i sugespalterne er fikseringsplanet ved en fordelagtig udførelsesform for indretningen ifølge opfindelsen udformet med en affasning, der fortrinsvis danner en vinkel på omkring 15° med materialebanens plan, ved de mod sugespalterne vendende kanter. Herved slipper luftstrømmen nemlig lettere materialebanens overflade og afbøjes ned i sugespalten.In order to obtain a better suction of the dust in the suction gaps, the fixing plane is, in an advantageous embodiment of the device according to the invention, formed with a bevel, which preferably forms an angle of about 15 ° with the plane of the material web, at the edges facing the suction gaps. As a result, the air flow releases the lighter material web surface and deflects into the suction slot.

Med henblik på yderligere at lette nævnte afbøjning kan suge- 3 144235 spalterne ved de sider, der har størst afstand fra fikseringsplanet, være udstyret med en væg, der kan hæves og sænkes.In order to further facilitate said deflection, the suction slots at the sides which are most distant from the fixation plane may be provided with a wall which can be raised and lowered.

I det følgende forklares opfindelsen nærmere i tilslutning til tegningen, der viser udførelsesformer for en støvsugeindretning ifølge opfindelsen, og hvor fig. 1 viser et længdesnit gennem en del af det baneformede materiale samt et snit I-I gennem den i fig. 2 viste, kombinerede blæse- og sugekasse, der foroven er udformet med blæseåbninger og sugespalter ifølge opfindelsen, og fig. 2 et snit II-II gennem den i fig. 1 viste, kombinerede blæse- og sugekasse.In the following, the invention will be explained in greater detail with reference to the drawing, which shows embodiments of a vacuum cleaner device according to the invention, and in which fig. 1 is a longitudinal section through a portion of the web-shaped material and a section I-I through the section of FIG. 2, the blower and suction box shown above are formed with blower openings and suction slots according to the invention, and fig. 2 shows a section II-II through the embodiment of FIG. 1, combined blower and suction box.

Tegningen viser et baneformet materiale 1, som skal støvsuges, medens det transporteres i den med pilen la angivne retning. I et parallelt med og op til materialebanen lfs overflade beliggende fikseringsplan 2 er udformet tre, tværs over materialebanen forløbende rakker af blæseåtrrin-ger 3. Blæseåbningerne 3a i de yderste rækker er udformet således, at de blæser luftstrømme mellem materialebarien og fikseringsplanet i det væsentlige parallelt med materialebanens bevægelsesretning med henblik på fiksering af banen. I den midterste række er blæseåbningerne 3b udformet på en sådan måde, at de blæser luftstrømme i retninger, der skærer materialebanen i en større vinkel, end det er tilfældet for de førstnævnte luftstrømme, med henblik på indtrængning i og løsrivelse af støv fra materialebanens yderlag, hvorved støvsugeeffekten bliver forbedret. Åbningerne 3b i midterrækken er vendt således, at de skiftevis blæser luftstrømme ud i samme retning og i modsat retning som materialebanens bevægelsesretning. Blæseåbningerne står gennem en blæse-kasse 4 i forbindelse med et tilførselsorgan for blæseluft, der ikke er vist på tegningen. På begge sider af fikseringsplanet, set i banens bevægelsesretning, er der udformet sugespalter 5 på en sådan måde, at de kan bortsuge støv sammen med den tidligere påblæste luft. Sugespalterne står i forbindelse med en sugekasse 6 med et organ til bortsugning af luft, der ikke er vist på tegningen. Ved dets mod sugespalterne 5 vendende kanter er fikseringsplanet 2 udformet med skråflader 2a, der danner en vinkel af størrelsesordenen 15° med planet, og som understøtter luftens og støvets afbøjning ned i sugespalterne. Sugespalternes ydervægge 7 kan i den viste udførelsesform hæves og sænkes for ved varierende luftmængder og skiftende materialetyper at gøre det muligt at gennemføre en enkel indstilling til en sådan afstand fra materialebanen, at dels den påblæste luft ikke strømmer forbi sugespalterne og ved dens transport af støv forårsager en ny påføring af støv 4 144235 på materialebanen,samt dels sikrer, at materialebanen under dens bevægelse ikke skraber mod de omtalte vægge og derved får yderlaget beskadiget. Dette er specielt vigtigt, hvis banens mod støvsugeindretningen vendende overflade er belagt med en eller anden endnu ikke tørret bestrygningssubstans.The drawing shows a web-shaped material 1 to be vacuumed while being transported in the direction indicated by the arrow 1a. In a fixing plane 2 located parallel to and up to the surface of the material web lf, three racks of blowing steps 3 are arranged transverse to the material web. The blowing openings 3a in the outer rows are designed to blow air flows between the material bar and the fixing plane substantially parallel. with the direction of movement of the material web in order to fix the web. In the middle row, the blow openings 3b are formed in such a way that they blow air streams in directions that intersect the material web at a greater angle than is the case for the first mentioned air streams, for penetration and release of dust from the outer web of the material web. thereby improving the vacuum cleaning effect. The openings 3b in the middle row are turned so that they alternately blow out air flows in the same direction and in the opposite direction as the direction of movement of the material web. The blow openings pass through a blow box 4 in connection with a blowing air supply means not shown in the drawing. On both sides of the fixation plane, seen in the direction of movement of the web, suction slots 5 are formed in such a way that they can absorb dust together with the previously inflated air. The suction slots are connected to a suction box 6 with a means for extracting air not shown in the drawing. At its edges facing the suction slots 5, the fixing plane 2 is formed with inclined faces 2a which form an angle of the order of 15 ° with the plane and which support the deflection of the air and the dust down into the suction slots. In the illustrated embodiment, the outer walls 7 of the suction gaps can be raised and lowered to allow for a simple adjustment to such a distance from the material path as varying air volumes and changing material types, that partly the blown air does not flow past the suction gaps and cause its dust to be transported. a new application of dust 4 144235 to the material web, and partly ensures that the material web during its movement does not scrape against the walls mentioned and thereby damage the outer layer. This is especially important if the surface of the web facing the vacuum cleaner is coated with some yet-dried coating substance.
