Abstract

The device for sorting of flat rings, especially of cover rings of rolling bearings, is intended for sorting according to orientation of the rings whose front surface is unevenly recessed. The device is formed by a guide board (1), whose front surface is equipped with a longitudinal supporting bar (7), feeding trough equipped with a feeder, and by a shifting continuous belt (2), while the third carrying wheel (4), which is equipped with at least one pushing-away arm (6), is connected with the inside circumference of the shifting continuous belt (2) between the driving wheel (3) and driven wheel (2). The pushing-away arm (6) is synchronized with the carrying wheel (4) in such a way that the pushing-away arm (6) is in advance in comparison with the carrying wheel (4) by the distance that measures to the radius of the flat ring. The flat rings that fall from the inlet trough on the longitudinal supporting bar (7) are shifted by the shifting continuous belt (2) along the longitudinal supporting bar (7), where sorting of the rings according to their orientation occurs by the effect of the pushing-away arm (6).<IMAGE>

Description

Vynález sa týká zariadenia na triedenie plochých krúžkov s roznym axiálnym medzikruhovým vybráním na ich čelách podlá orientácie Jedného čela, najma krycích krúžkov valivých ložisk.The invention relates to a device for sorting flat rings with different axial annular recesses on their faces according to the orientation of one face, in particular the cover rings of rolling bearings.

Z literatúry sú známe triediace a orientovacie zariadenia, ktoré triedia alebo orientuje súčlastky podlá skosenia alebo zaoblenia hrany na vonkajšej plocha. Súčiastky, u ktorých toto skosenie alebo zaoblenie chýba, alebo je na oboch stranách rovnaké, nedajú sa pomocou týchto zariadeni triedit. Známe je tiež zariadenie na triedenie plochých krúžkov s radiálně von otočenou súosou rotačnou plochou, no Jeho použitie je značné obmedzené tvarom axiálneho přesilu a je schopné triedit len určitý - konkrétny tvar krúžkov. Na ' prevažnú vačšinu krycích krúžkov je zariadenie nevhodné a triedenie sa musi robit ručně s velmi nizkou produktivitou.Sorting and orientation devices are known in the literature to classify or orient the components by beveling or rounding the edge to the outer surface. Components lacking or being the same on both sides of the chamfer or rounding cannot be sorted by these devices. Also known is a device for sorting flat rings with a radially outwardly rotated coaxial rotating surface, but its use is greatly limited by the shape of the axial overpower and is able to sort only a certain - specific shape of the rings. For most cover rings, the device is unsuitable and sorting has to be done manually with very low productivity.

Uvedené nedostatky odstraňuje zariadenie na triedenie plochých krúžkov s roznymi axiálnymi medzikruhovými vybraniami na ich čelách, najma krycích krúžkov gulkových ložisk, ktoré pozostáva z vodiacej došky, opatrenej na prednej straně pozdlžnou podpěrnou lištou, prívodným žlabom s dávkovačom a z presúvacieho pásu, opatřeného unášacimi palcami. Caho podstata spočívá v tom, že nekonečný presúvacl pás, určený na presúvanie plochých krúžkov, je umiestnený na zadnej straně vodiacej došky a medzi hnacie a hnané koleso (napr. retazové) je vnútorný obvod nekonečného presúvacieho pásu napojené tretie unášacie koleso opatřené najmenej jedným odtláčasim ramenom, ktoré je s unášacím kolesom a nekonečným pásem synchronizované tak, že odtláčacie rameno je před unášacim palcom v předstihu o vzdialenost rovnú poloměru plochého krúžku.These drawbacks are eliminated by a device for sorting flat rings with different axial annular recesses on their faces, in particular ball bearing cover rings, which consists of a guide that is provided with a longitudinal support strip on the front, a dispenser trough with a transfer belt provided with a carrier. The principle is that the endless transfer belt for moving the flat rings is located on the back of the guide thatch and between the drive and driven wheel (e.g., the chain) is an inner circumference of the endless transfer belt connected to a third carrier wheel with at least one trailing arm which is synchronized with the drive wheel and the endless belt so that the push arm is in front of the drive thumb in advance by a distance equal to the radius of the flat ring.

Podstata je ňalej v tom,,že vo vodiacej doske, súbežne s presúvacim pásom a odtláčacim ramenom, sú vytvořené dve pozdížne štrbiny a pracovná poloha vodiacej došky,‘Určená jej čelnou rovinou, je od vertikálnej roviny odkloněná o uhol 30° až 45°, ako aj v tom, že přesah odtláčacieho ramena nad čelnú pracovnú rovinu vodiacej došky je vačši ako híbka menšieho axiálneho vybrania plochého krúžku a súčasne menši alebo rovný híbke vačšieho axiálneho vybrania plochého krúžku.The point is further that two longitudinal slots are formed in the guide plate parallel to the transfer belt and the push arm, and the working position of the guide that is determined by its front plane is inclined by an angle of 30 ° to 45 ° from the vertical. and in that the extension of the push arm above the front working plane of the thatch is more than the depth of the smaller axial recess of the flat ring and at the same time less than or equal to the depth of the larger axial recess of the flat ring.
