Description
454 085 z med tätningsytorna behöver inte fästas med några komplicerande fästorgan vid sugkoppens cylindriska vägg, utan det räcker om de två delarna häftar vid varandra genom friktion. Så fort undertryck uppstår i sugkoppen sugs den hylsformiga delen fast på sugkoppen, och det finns ingen risk för att tätningsytorna skall lossna eller förskjutas under lyftningen eftersom dessa är fast förenade med den hylsformiga delen. För att inte läckage skall kunna uppstå mellan den hylsformiga delen och sugkoppens väggar vid kraftigt undertryck är tätningen mellan dessa lämpligen utförd som en självverkande sådan, så att anliggningskraften mellan dessa ökar med växande undertryck. 454 085 z with the sealing surfaces does not need to be fastened with any complicated fastening means to the cylindrical wall of the suction cup, but it is sufficient if the two parts adhere to each other by friction. As soon as negative pressure arises in the suction cup, the sleeve-shaped part is sucked onto the suction cup, and there is no risk of the sealing surfaces coming loose or displaced during lifting as these are firmly connected to the sleeve-shaped part. In order to prevent leakage between the sleeve-shaped part and the walls of the suction cup during strong negative pressure, the seal between them is suitably designed as a self-acting one, so that the abutment force between them increases with increasing negative pressure.
En ytterligare fördel med fäst- och tätningsanordningen hos gripanordningen enligt uppfinningen är, att den hylsformiga delens undre parti kan utformas som_en mjukt fjädrande tätningsyta och dessutom kan utformas att omge sug- koppens cylindriska vägg invid sugöppningen som ett stötdämpande skyddsskikt.A further advantage of the fastening and sealing device of the gripping device according to the invention is that the lower part of the sleeve-shaped part can be designed as a softly resilient sealing surface and can also be designed to surround the cylindrical wall of the suction cup next to the suction opening as a shock-absorbing protective layer.
Uppfinningen är närmare tydliggjord i det följande under hänvisning till bifogade ritning, som visar två olika som exempel valda utföringsformer av anordningen enligt uppfinningen.The invention is further elucidated in the following with reference to the accompanying drawing, which shows two different exemplary embodiments of the device according to the invention.
Fig. l visar schematiskt en vertikalsektion genom en del av lyftanordningen enligt en första utföringsform av uppfinningen och fig. 2 visar samma sek- tion genom en andra utföringsform.Fig. 1 schematically shows a vertical section through a part of the lifting device according to a first embodiment of the invention and Fig. 2 shows the same section through a second embodiment.
I fig. l visas en lyftanordning medensugkopp l med uppifrån sett oval form.Fig. 1 shows a lifting device with suction cup 1 with an oval shape seen from above.
Sugkoppen har en oval ovansida 2 med en nedâtriktad, sidovägg 3, vars under- kant 4 är omvikt och bildar en sugöppning 5. Strax under ovansidan 2 är en inställbar bottenplåt 6 fastsatt, och ovanpå ovansidan 2 är en suganordning 7 med ett sughål 8 till sugkoppens inre fastsatt, liksom en lyftögla 9.The suction cup has an oval upper side 2 with a downwardly directed, side wall 3, the lower edge 4 of which is folded over and forms a suction opening 5. Just below the upper side 2 is an adjustable bottom plate 6 fixed, and on top of the upper side 2 a suction device 7 with a suction hole 8 for the inside of the suction cup attached, as well as a lifting eye 9.
Sugkoppen l är försedd med en lätt monteringsbar och lätt löstagbar tät- ningsanordning l0 bestående av en ringformig gummilist ll - här visad omon- terad - med samma ovala form som sidoväggen 3 och med en på gummilistens insida fast anbragt tätningslist l2 med en inåt mot sugöppningens 5 mitt riktad tätningsyta l3. Tätningslisten l2 består av mjukt fjädrande cell- gummimaterial.The suction cup 1 is provided with an easily mountable and easily detachable sealing device 10 consisting of an annular rubber strip 11 - shown here unmounted - with the same oval shape as the side wall 3 and with a sealing strip l2 fixed on the inside of the rubber strip with an inwardly facing suction opening. 5 center directed sealing surface l3. The sealing strip l2 consists of softly resilient cellular rubber material.
...M __... .__._._... 3 454 085 Den ovala gummilisten 11 är försedd med en axiell slits 14 så utformad, att gummilisten ll kan skjutas in på den ovala sidoväggen 3, varvid dennas undre del och den omvikta kanten 4 upptages av slitsen 14 med gummilistens utanför slitsen l4 belägna del 15 fjädrande anliggande mot väggens 3, 4 utsida.... M __... .__._._... 3 454 085 The oval rubber strip 11 is provided with an axial slot 14 so designed that the rubber strip 11 can be slid into the oval side wall 3, the lower part thereof and the folded edge 4 is received by the slot 14 with the rubber strip part 15 outside the slot 14 resiliently abutting against the outside of the wall 3, 4.
Listen ll är vidare försedd med en undre, koniskt utkragad del 16, vars undre kant 17 fungerar som en mjukt fjädrande, nedåtriktad tätningsyta.The strip 11 is further provided with a lower, conically cantilevered part 16, the lower edge 17 of which functions as a softly resilient, downwardly directed sealing surface.
De båda tätningsytornas 13, 17 funktion är densamma som den vid den i svenska patentansökningen 8301268-2 beskrivna lyftanordningen, d v s tät- ningsytan 17 skapar den första tätningen mot en icke visad säcks ovansida, varefter ett parti av säckens ovansida sugs upp utmed tätningsytan 13 till anliggning åtminstone partiellt mot bottenplâten 6. Den egentliga tät- ningen mellan säckens ovansida och tätningsanordningen 10 sker därvid vid tätningsytan 13.The function of the two sealing surfaces 13, 17 is the same as that of the lifting device described in Swedish patent application 8301268-2, i.e. the sealing surface 17 creates the first seal against the upper side of a bag (not shown), after which a portion of the upper side of the bag is sucked up along the sealing surface 13 to abutment at least partially against the bottom plate 6. The actual sealing between the top of the bag and the sealing device 10 then takes place at the sealing surface 13.
Fig. 2 visar ett modifierat utförande av listen ll, som här är betecknad Zl och upptill är försedd med utåtriktade lameller 22, så utformade, att när listen Zl trycks in mot väggens 3 insida i sugkoppen 1 lamellerna viks nedåt något till det i fig. 2 visade läget.Fig. 2 shows a modified embodiment of the strip 11, which is here denoted Z1 and is provided at the top with outwardly directed slats 22, designed so that when the strip Z1 is pressed against the inside of the wall 3 in the suction cup 1 the slats are folded down slightly to that in fig. 2 showed the situation.
Tätningslisten 12 måste i detta fall vara infattad i en U-profil 23 av stål för att listen 21 skall bibehålla sin ovala form vid undertryck hos sugkoppen 1, då lamellerna av undertrycket pressas mot väggens 3 insida, eller på annat sätt vara förstärkt mot förändring av den ovala formen.The sealing strip 12 must in this case be framed in a U-profile 23 of steel in order for the strip 21 to maintain its oval shape at negative pressure of the suction cup 1, when the lamellae of the negative pressure are pressed against the inside of the wall 3, or otherwise reinforced against change of the oval shape.
Väggen 3 kan i detta fall alternativt ha en koniskt utkragad underdel 4' i stället för en ombockad kant 4, vilket underlättar listens 21 inskjutning i den cylindriska väggen 3 och även tjänstgör som stöd för listen 21 i infört läge.The wall 3 can in this case alternatively have a conically cantilevered lower part 4 'instead of a bent edge 4, which facilitates the insertion of the strip 21 into the cylindrical wall 3 and also serves as a support for the strip 21 in the inserted position.
Konturen av en i sugkoppen insugen överdel av en säck är markerad med beteckningen 24. 454 085 4 Uppfinningen är självfallet inte begränsad till de visade utförings- formerna utan kan modifieras på åtskilliga sätt inom ramen för den i patentkraven definierade uppfinningen. Sålunda behöver inte nödvändigt- vis tätningsytorna l3 vara anordnade på vid listerna ll, Zl fast anbragta tätningslister 12, utan tätningsytorna kan vara utformade direkt på en del av listerna ll, Zl under förutsättning att erforderlig elasticitet hos tätningsytan kan åstadkommas.The contour of an upper part of a sack sucked into the suction cup is marked with the designation 24. 454 085 The invention is of course not limited to the embodiments shown but can be modified in several ways within the scope of the invention defined in the claims. Thus, the sealing surfaces 13 need not necessarily be arranged on sealing strips 12 fixedly attached to the strips 11, Z1, but the sealing surfaces can be formed directly on a part of the strips 11, Z1, provided that the required elasticity of the sealing surface can be achieved.
