Abstract
Abstract A pick-out device for a labelling machine comprises at least one pick-out blade rotatable about a first axis in one direction and connected to a crankshaft or other eccentric means that is rotatable about a second parallel axis in the opposite direction or in the same direction and is capable of imparting to the pickout blade not only this rotational movement about the second axis but also radial movement outwardly or inwardly with respect to the first axis, so as to enable the pick-out blade to pick a label out of a label stack, means to guide the pick-out blade radially and means to apply gum to the pick-out blade.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
120 words
A pick-out device for a labelling machine comprising a pick-out blade rotatable about a first axis in one direction, a crankshaft rotatable about a second parallel axis, removed from said first axis, in the opposite direction or in the same direction with respect to the rotation of said first axis and connected to said pick-out blade and capable of imparting to said pick-out blade not only rotational movement about said second axis but also radial movement outwardly or inwardly with respect to said first axis, means to guide said pick-out blade radially and means to apply gum to said pick-out blade, whereby said blade picks out the foremost label of a stack of labels without rolling over said foremost label.
Claim 2
Dependent Claim
120 words
A pick-out device for a labelling machine comprising a pick-out blade rotatable about a first axis in one direction, a crankshaft rotatable about a second parallel axis, removed from said first axis, in the opposite direction or in the same direction with respect to the rotation of said first axis and connected to said pick-out blade and capable of imparting to said pick-out blade not only rotational movement about said second axis but also radial movement outwardly or inwardly with respect to said first axis, means to guide said pick-out blade radially and means to apply gum to said pick-out blade, whereby said blade picks out the foremost label of a stack of labels without rolling over said foremost label.
Claim 3
Dependent Claim
20 words
A pick-out device as claimed in claim 1 wherein said crankshaft is rotated by a cam and gear quadrant arrangement.
Claim 4
Dependent Claim
20 words
A pick-out device as claimed in claim 2 wherein said crankshaft carries a spur gear in mesh with said quadrant.
Claim 5
Dependent Claim
30 words
A pick-out device as claimed in claim 1 comprising a plate rotatable about said first axis and a plurality of said pick-out blades and their crankshafts located on said plate.
Claim 6
Dependent Claim
23 words
A pick-out device as claimed in claim 1 further comprising a central drive shaft to a carrier plate, said plate supporting said crankshaft.
Claim 7
Dependent Claim
31 words
A pick-out device as claimed in Claim 5 wherein a main bearing of said crankshaft is displaced from the centre of rotation of said carrier along a radius of said carrier.
Claim 8
Dependent Claim
27 words
A pick-out device as claimed in claim 5 wherein said crankshafts are supported at each end by two spaced carrier plates fixed to a central drive shaft.
Claim 9
Dependent Claim
19 words
A pick-out device as claimed in claim 5 comprising six pick-out blades spaced 60* apart around said first axis.
Claim 10
Dependent Claim
145 words
A pick-out device for a labelling machine comprising a pickout blade rotatable about a first axis in one direction, a crankshaft rotatable about a second parallel axis, removed from said first axis in the opposite direction or in the same direction and connected to said pick-out blade and capable of imparting to said pick-out blade not only rotational movement about said second axis but also radial movement outwardly or inwardly with respect to said first axis, means to guide said pick-out blade radially and means to apply gum to said pick-out blade; whereby said blade picks out the foremost label of a stack of labels without rolling over said foremost label, wherein a pick-out blade carrier carries said pick-out blade and an end of said carrier remote from said blade is slotted to receive a central drive shaft which is coincident with said first axis.
Claim 11
Dependent Claim
145 words
A pick-out device for a labelling machine comprising a pickout blade rotatable about a first axis in one direction, a crankshaft rotatable about a second parallel axis, removed from said first axis in the opposite direction or in the same direction and connected to said pick-out blade and capable of imparting to said pick-out blade not only rotational movement about said second axis but also radial movement outwardly or inwardly with respect to said first axis, means to guide said pick-out blade radially and means to apply gum to said pick-out blade; whereby said blade picks out the foremost label of a stack of labels without rolling over said foremost label, wherein a pick-out blade carrier carries said pick-out blade and an end of said carrier remote from said blade is slotted to receive a central drive shaft which is coincident with said first axis.
