Abstract
Abstract The device for charging on and discharging from cheese frames (20) yarn cheeses (21) is characterized in that it comprises a pair of arms (51, 52) provided at the lower end with gripping means and vertically movable together with possibility to be swinged therebetween and a center guide rod arranged between the arms and having at its lower end gripping means. The pair of arms are fixed on a carriage provided with means for swinging the arms and capable of vertically moving in opposed directions so as to shift the gripping arms from a lifted position to a lowered position and viceversa . In the lower position the arms grip the cheeses by means of their gripping means and lift them so as to be inserted in the center guide rod where are retained by the gripping means thereof. The swinging of the gripping arms has the function to position them accurately in the void spaces existing between adjacent cheese stacks so that they enter the void spaces in order to pick-up or lay down the cheese stack.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
196 words
1) Device for charging on and discharging from cheese frames yarn cheeses, having the cheese frame formed of a plate having a central post and a number of columns supporting the cheeses, characterized in that the device comprises a pair of arms provided on the lower end with gripping means and vertically movable together with the possibility of being swinged to each other and a fixed center guide rod located between said pair of arms and having at its lower end gripping means, so that said center guide rod can be placed on the extension of the cheese frame column intended to be charged or discharged and so act as a guide for the cheeses which are lifted by the gripping means of the arms engaging the cheese for lifting or lowering it, whereas said gripping means of said center guide rod are intended to lock the cheese already threaded thereon, thereby preventing the cheese to fall down when said arms are again moved for gripping a next cheese, the device being further provided with means for moving it vertically and horizontally in order to position it above the column intended to be charged and discharged.
Claim 2
Dependent Claim
196 words
