Patent ID: 8668429

Claim:
Depalleting device ( 1 ) for unloading products ( 2 ) provided in a stack ( 3 ) comprising i) a mounting table ( 8 ), the mounting table being adjustable linearly in a guiding arrangement ( 10 ) via a feed drive ( 9 ) having a first drive motor ( 16 ), and the mounting table having a support frame ( 17 ), ii) a conveying device ( 4 ) arranged on the mounting table ( 8 ) and connected to a second drive motor ( 5 ), iii) a receiving conveying device ( 23 ) arranged at least at one of the front ends of the conveying device ( 4 ), the receiving conveying device ( 23 ) being mounted adjustably on the support frame ( 17 ) relative to the conveying device ( 4 ) and against the action of at least one support device ( 47 ) and having a conveying roller ( 24 ) for lifting at least one product ( 2 ) in the stack ( 3 ), the conveying roller ( 24 ) being connected to a third drive motor ( 27 ), and the third drive motor ( 27 ) being of the type of an electric speed-controlled motor, iv) a detecting means ( 52 ) for detecting either a support force ( 51 ) applied on the conveying roller ( 24 ) upon contact with the at least one product ( 2 ) to be depalleted or a driving torque of the third drive motor ( 27 ), the detecting means ( 52 ) being connected to a control ( 54 ) and v) the control ( 54 ) being connected to the third drive motor ( 27 ) and for controlling a driving speed of the third drive motor ( 27 ) for the conveying roller ( 24 ) either on the basis of the support force applied on the conveying roller ( 24 ) upon contact with the at least one product ( 2 ) to be depalleted or on the basis of the driving torque of the third drive motor ( 27 ).
