Abstract
A method for unloading from a supporting element a stack of blanks resting on an interlayer including one or more protrusions that delimit one or more channels. The method including positioning a robotic arm on which a handling member is mounted, including one or more prongs and a gripping element movable between a gripping position and a disengagement position; inserting each prong between the stack of blanks and the interlayer, so that each prong engages a respective channel; moving the gripping element until reaching the gripping position to clamp the stack of blanks between the gripping element and each prong; lifting the stack of blanks to unload the stack of blanks; and moving the stack of blanks in space.
Claims13
A method for unloading from a support element a stack of blanks resting on an interlayer, wherein said interlayer comprises one or more protrusions that superiorly define a supporting surface on which said stack of blanks rests and that delimit one or more channels arranged at a lower level than said supporting surface, said method comprising:
- positioning a robotic arm on which a handling member is mounted, wherein said handling member comprises one or more prongs and a gripping element movable between a gripping position and a disengagement position;
- with said gripping element in the disengagement position, inserting said one or more prongs between said stack of blanks and said interlayer, so that each of said one or more prongs engages a respective channel of said one or more channels;
- moving said gripping element towards said one or more prongs until reaching said gripping position to clamp said stack of blanks between said gripping element and said one or more prongs;
- with said stack of blanks clamped between said gripping element and said one or more prongs, lifting said stack of blanks via said handling member to unload said stack of blanks from said support element;
- and
- via said robotic arm, moving said stack of blanks clamped between said gripping element and said one or more prongs in space.
The method for feeding a stack of blanks to a packaging machine, comprising the method for unloading said stack of blanks from a support element according to any one of the preceding claims and, after said releasing said stack of blanks, feeding said stack of blanks to said packaging machine.
