Abstract

Device for moving plate-like objects 4, which device comprises a body 1 and suction cups 3 located in the body, which cups with a negative pressure applied to them adhere to the object 4. The device comprises blower units 2 located in connection with the suction cups 3, which units through the blowing action that they exert during lifting prevent a vacuum from forming between superimposed objects and thereby prevent a plurality of superimposed objects 4 being lifted in the same lifting operation. <IMAGE>

LAITTEISTO LEVYMÄISTEN KAPPALEIDEN SIIRTÄMISEKSIAPPARATUS FOR TRANSFERRING PLATES

Tämän keksinnön kohteena on patenttivaatimuksen 1 johdanto-osan mukainen laitteisto levymäisten kappaleiden siirtämi-5 seksi.The present invention relates to an apparatus according to the preamble of claim 1 for transferring plate-like bodies.

Epäkohtana nykyisissä levyjen siirtoon tarkoitetuissa, imukupeilla varustetuissa siirtolaitteistoissa on se, että nostettaessa huokoisia levyjä, esimerkiksi raakalastulevypa-10 loja, päällekkäisten levyjen kautta kulkee läpi-imu, jonka seurauksena levyjen väliin syntyy tyhjiö. Tällöin nostettaessa päällimmäistä levyä pinosta sen mukana nousee useampia levyjä.A disadvantage of current transfer devices with suction cups for transferring plates is that when porous plates, for example slabs of green chipboard, are lifted, suction passes through the overlapping plates, as a result of which a vacuum is created between the plates. In this case, when the uppermost plate is lifted from the stack, several plates rise with it.

15 Tämän keksinnön tarkoituksena on poistaa tunnetun tekniikan epäkohdat ja saada aikaan esimerkiksi raakalastulevypalojen siirtämiseen soveltuva laitteisto. Keksinnön mukaisessa laitteistossa on imukuppien yhteyteen sovitettu puhallus oheisten patenttivaatimusten mukaisesti.The object of the present invention is to eliminate the drawbacks of the prior art and to provide, for example, an apparatus suitable for transferring pieces of raw chipboard. The apparatus according to the invention has a blow arranged in connection with the suction cups in accordance with the appended claims.

2020

Keksinnön mukainen laitteisto soveltuu mm. vanerointipuris-timille, joissa käytetään useita eri levypaksuuksia ja vaihtelevia levykokoja. Laitteisto kumoaa läpi-imun, ja levyjen väliin menevä ilma estää tyhjiön syntymisen niiden 25 väliin. Näin estetään useamman levyn nouseminen samanaikaisesti.The apparatus according to the invention is suitable e.g. for plywood presses using several different plate thicknesses and different plate sizes. The equipment cancels the suction through, and the air passing between the plates prevents the creation of a vacuum between them. This prevents multiple discs from rising at the same time.

Seuraavassa keksintöä selostetaan yksityiskohtaisemmin esimerkin avulla viittaamalla oheiseen piirustukseen, joka 30 esittää keksinnön mukaista siirtolaitteistoa.In the following, the invention will be described in more detail by way of example with reference to the accompanying drawing, which shows a transfer apparatus according to the invention.

Laitteistoon kuuluu runko 1 sekä sen alaosaan kiinnitetyt imukupit 3, jotka tarttuvat levyihin 4, ja joiden avulla lastulevyt 4 voidaan nostaa levypinosta ja siirtää muualle 35 sinänsä tunnetun siirtokoneiston avulla, jota ei ole tässä esitetty.The apparatus comprises a frame 1 and suction cups 3 attached to its lower part, which engage the plates 4 and by means of which the chipboards 4 can be lifted from the plate stack and moved elsewhere by means of a transfer mechanism known per se, not shown here.

2 95^5b2 95 ^ 5b

Kunkin imukupin 3 ympärille on runkoon kiinnitetty puhallus-kuppi 2. Puhalluskupin 2 pinta-ala on suurempi kuin imukupin 3, joka näin jää puhalluskupin sisään. Puhalluskupin 2 aikaansaama puhallus kumoaa edellä kuvatun läpi-imun, ja 5 levyjen 4 väliin puhallettava ilma estää tyhjiön syntymisen levyjen 4 väliin.A blowing cup 2 is attached to the body around each suction cup 3. The area of the blowing cup 2 is larger than that of the suction cup 3, which thus remains inside the blowing cup. The blow produced by the blow cup 2 cancels the suction described above, and the air blown between the plates 4 prevents the creation of a vacuum between the plates 4.

Imukupin 3 yläosaan on sijoitettu tiiviste 5, joka tiivistää imukupin 3 yläreunan siten, että imuun tarvittava alipaine 10 ja puhalluskupissa 2 oleva, puhallukseen tarvittava ylipaine pysyvät erillään toisistaan. Imua kuvataan imukuppiin 3 kulkevilla nuolilla ja puhallusta puhalluskupista 2 lähtevillä nuolilla. Puhallusta kuvaavista nuolista nähdään, että puhallus ulottuu myös päällekkäisten levyjen 4 väliin ja 15 estää näin useamman levyn nousemisen päällimmäistä levyä 4 nostettaessa.A seal 5 is placed in the upper part of the suction cup 3, which seals the upper edge of the suction cup 3 so that the vacuum 10 required for suction and the overpressure required for blowing in the blow cup 2 remain separate from each other. Suction is illustrated by arrows leading to the suction cup 3 and blowing by arrows leaving the blowing cup 2. It can be seen from the arrows describing the blowing that the blowing also extends between the overlapping plates 4 and thus prevents several plates from rising when the uppermost plate 4 is lifted.

Alipaine saadaan aikaan alipainelaitteella (ei esitetty), joka imee ilmaa imukupista rungon 1 läpi kulkevan putken 6 20 kautta. Ylipaine taas ohjataan ylipainelaitteesta (ei esitetty) puhalluskuppiin toisen putken 7 ja kupin läpiviennin 8 kautta. Mikäli alipainelaitteena käytetään ejektoria, voidaan ylipaine saada saman ejektorin painepuolelta.The vacuum is provided by a vacuum device (not shown) which sucks air from the suction cup through a pipe 6 20 passing through the body 1. The overpressure, on the other hand, is directed from the overpressure device (not shown) to the blow cup through the second pipe 7 and the cup bushing 8. If an ejector is used as the vacuum device, the overpressure can be obtained from the pressure side of the same ejector.

-...25 Imu- ja puhalluskuppien 2, 3 pinta-alat sovitetaan kunkin sovellutuksen mukaan, samoin kuin ali- ja ylipaineen suuruudet ja niiden päälläoloajat siten, että haluttu lopputulos saavutetaan. Alipaineen tulee kuitenkin kytkeytyä ennen ylipainetta, ja ylipaineen tulee olla kytkeytyneenä niin 30 kauan, kunnes siirtolaitteisto on nostanut levyn 4 irti levypinosta (kuormasta).-... 25 The areas of the suction and blow cups 2, 3 are adapted to each application, as well as the magnitudes of underpressure and overpressure and their on-time so that the desired result is achieved. However, the negative pressure must be switched on before the overpressure, and the overpressure must be switched on until the transfer device has lifted the plate 4 off the plate stack (load).

Alan ammattimiehelle on selvää, että keksinnön eri sovellu-tusmuodot eivät rajoitu yksinomaan edellä kuvattuun esimerk-35 kiin, vaan ne voivat vaihdella jäljempänä esitettävien patenttivaatimusten puitteissa.It will be clear to a person skilled in the art that the various embodiments of the invention are not limited exclusively to the example described above, but may vary within the scope of the claims set out below.
