Within an substitute embodiment, the coil upender comprises a dealing with robot made and situated to grab (i.e. directly from the shuttle) single moves situated using the axis thereof around horizontal and swivel these people to drive them to some placement with all the axis thereof roughly straight.
Further advantageous embodiments and possible additional characteristics of the coil upender according to the invention are indicated hereunder with reference to some non-limiting embodiments and in the appended claims.
According to a specific aspect, the invention also relates to a robot for handling rolls of web material, particularly although not exclusively for use in a coil upender of the above type, comprising an articulated arm, movable according to a plurality of numerically controlled axes and supporting a suction head. According to a possible embodiment, the suction head has a surface for gripping the rolls substantially flat in shape and approximately semi-circular. Advantageously, the suction power head can have suction locations that may be triggered selectively like a function of the diameter in the roll to become dealt with.
The suction areas are formed of substantially semi-annular portions, in fluid connection with a suction duct, according to a preferred embodiment of the invention. Also supplied are choice participants to selectively hook up stated considerably semi-annular portions to the suction power duct. The assortment members are able to make up a control device.
Within a further more embodiment, the top of your robot may have a plurality of personal-shutting valves, associated with a suction duct and located with all the suction power aspect towards gripping surface of the suction mind of your robot. The personal-closing valves could be built with individual close-away from participants which close the valve when there is no area of any roll to get interested by way of stated brain facing it.
In the especially favored embodiment in the innovation, a sensing unit to initialize suction power once the head is in closeness to some roll is associated to mentioned brain.
