Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 189 words
A transferring and stacking device for a cigarette pack cellowrap machine having conveying means for delivering packs one after another to be cellowrapped and a step by step rotatably driven star wheel with a plurality of radial pockets receiving successive cigarette packs each with an associated cellophane sheet, comprising: means for retaining a plurality of cigarette packs one above the other in a stack, first and second transferring means continuously reciprocating each in phase opposition to the other and having a transverse component of displacement during reciprocation causing each transferring means to pass through the path of movement of the packs during the forward operating strokes and to prevent interference with the path of movement of the packs during the return strokes, said first transferring means removing cigarette packs one after another from said conveying means and delivering each such pack to the bottom of the stack held by said retaining means causing the uppermost pack of the stack to rise, said second transferring means removing the uppermost pack from the stack and delivering such packs each with a sheet of cellophane to successive pockets of said star wheel.
Claim 2
Dependent Claim 189 words
A transferring and stacking device for a cigarette pack cellowrap machine having conveying means for delivering packs one after another to be cellowrapped and a step by step rotatably driven star wheel with a plurality of radial pockets receiving successive cigarette packs each with an associated cellophane sheet, comprising: means for retaining a plurality of cigarette packs one above the other in a stack, first and second transferring means continuously reciprocating each in phase opposition to the other and having a transverse component of displacement during reciprocation causing each transferring means to pass through the path of movement of the packs during the forward operating strokes and to prevent interference with the path of movement of the packs during the return strokes, said first transferring means removing cigarette packs one after another from said conveying means and delivering each such pack to the bottom of the stack held by said retaining means causing the uppermost pack of the stack to rise, said second transferring means removing the uppermost pack from the stack and delivering such packs each with a sheet of cellophane to successive pockets of said star wheel.
Claim 3
Dependent Claim 101 words
The stacking and transferring device in accordance with claim 1, and said first transferring means comprising: a pair of stacking mechanisms operating in parallel timed relationship and symmetrically opposite from opposite sides of the stack in relation to the feed belt, said stacking mechanisms being provided with respective engaging means operating opposite to each other in pairs, with a displacement component in the direction of the stack and a displacement component transverse thereto, and the transverse component causing said respective engaging means to move along a path not interfering with said belt substantially during the complete return stroke of said means.
Claim 4
Dependent Claim 113 words
The stacking and transferring device in accordance with claim 2, and each of said stacking mechanisms being substantially an articulated parallelogram mechanism comprising: two equal crank disks rotatably driven around superimposed axes, a connecting rod coupling said crank disks to each other and carrying one of said engaging means, each of said engaging means being a fork maintained in the horizontal while being moved vertically by said respective connecting rod, and the horizontal displacement component bringing said fork to engage and transfer a pack from said belt to the bottom of the stack during the forward operating stroke and moving said fork along a non-interfering path with said belt during the return stroke.
Claim 5
Dependent Claim 103 words
The stacking and transferring device in accordance with claim 3, and said second means comprising: a pair of transferring elements, substantially operating in the horizontal, in correlation of functional parallelism with opposed symmetry in relation to the transfer path towards the wheel pocket, each of said elements being a pair of parallel-axis rotatable cranks and of a connecting rod coupling said cranks together, and each connecting rod having a plunger engaging and moving the uppermost pack of the stack along a path to said star wheel during the forward operating and laterally along a non-interfering path with the stack during each return stroke.
