Abstract

Dispositivo di sollevamento di una tavola girevole, con una tavola girevole (12) provvista di un piano a comando girevole (14), sul quale piano è montato un dispositivo di sollevamento che sorregge una slitta (30), spostabile in su ed in giù in direzione verticale in un'incastellatura di guida (28), dove sulla slitta è previsto un perno di trascinamento sporgente in senso rettangolare rispetto alla direzione di sollevamento, la cui estremità libera ingrana in una scanalatura di comando (42) ricavata nella superficie tangenziale di un rullo cilindrico verticale (32) a comando girevole. Il perno di trascinamento è alloggiato rigido in un supporto, il quale a sua volta è alloggiato spostabile di un tratto delimitato in direzione verticale nella slitta (30), dove il supporto è precaricato in una posizione teorica intermedia sulla slitta (30) tramite elementi a molla, dalla quale posizione è spostabile con aumento del precarico a molle alla presenza di un ostacolo alla slitta (30) durante la sua corsa di sollevamento od il suo arresto contro battute nella posizione finale corsa nella zona preselezionata tramite il tratto di spostamento delimitato. Sulla slitta (30) e sul supporto perno sono previsti elementi in interazione di un dispositivo elettrico di manovra, il quale durante uno spostamento relativo rispetto al supporto viene commutato dallo stato di comando esistente nella posizione teorica intermedia, disinnestando così il comando elettromotorico (36) del rullo cilindrico (32).Lifting device of a rotating table, with a rotating table (12) provided with a rotating control table (14), on which a lifting device is mounted which supports a slide (30), which can be moved up and down in vertical direction in a guide frame (28), where on the slide there is a driving pin protruding in a rectangular direction with respect to the lifting direction, the free end of which engages in a control groove (42) obtained in the tangential surface of a vertical cylindrical roller (32) with rotating control. The driving pin is rigidly housed in a support, which in turn is housed displaceable by a section delimited in a vertical direction in the slide (30), where the support is preloaded in an intermediate theoretical position on the slide (30) by means of spring, from which position it can be moved with an increase in the spring preload in the presence of an obstacle to the slide (30) during its lifting stroke or its stop against stops in the final stroke position in the preselected area through the delimited movement section. On the slide (30) and on the pivot support there are elements in interaction of an electric maneuvering device, which during a relative movement with respect to the support is switched from the existing control state to the intermediate theoretical position, thus disengaging the electromotor control (36) of the cylindrical roller (32).
