Claim 3
Dependent Claim
51 words
A labelling device as claimed in claim 1 including second guide means for effecting reciprocal movement of said arm member with respect to said main body member during movement of said head between said first and second positions to move said head radially into and out of said label storage station.
Claim 4
Dependent Claim
79 words
A labelling device as claimed in claim 2 wherein said first guide means includes a cam track means extending about said central axis and a cam follower means mounted on said head, said cam track means including a node disposed in advance of said label storage station and said cam follower means including a trailing cam follower arm projecting from said head for engaging said node as said head approaches, passes through and withdraws from said label storage station.
Claim 5
Dependent Claim
69 words
A labelling device as claimed in claim 3 wherein said second guide means includes a second cam track extending about said central axis and a second cam follower mounted on said arm member, said second cam track having a node radially aligned with said label storage station for guiding said second cam follower towards said label storage station during movement of said head between said first and second positions.
Claim 6
Dependent Claim
82 words
A labelling device as claimed in claim 1 wherein said means for securing a label to said outer surface of said head includes first and second suction passage means, said first suction passage means opening at said outer surface of said head adjacent trailing edge thereof and said second suction passage means opening at said outer surface of said head adjacent said leading edge thereof, and means for independently connecting said first and second suction passage means to a source of vacuum.
Claim 7
Dependent Claim
47 words
A labelling device as claimed in claim 1 wherein a plurality of arm members are slidably mounted on said main body member at circumferentially spaced intervals whereby a plurality of labels are transferred in response to each rotation of said main body member about said central axis.
Claim 8
Dependent Claim
43 words
A labelling device as claimed in claim 1 wherein said outer surface of said head has an arc of curvature generated from said central axis of a radius equal to the distance from said outer surface of said head to said central axis.
Claim 9
Dependent Claim
76 words
A labelling device as claimed in claim 7 wherein said glue applicator station includes roller applicator means mounted for rotation about an axis parallel to said central axis, said roller having an applicator surface disposed substantially tangentially with respect to the path of travel of said head through said glue applicator station whereby said roller is rotatably driven by engagement with said head as it passes through said applicator station to apply glue to said label.
Claim 10
Dependent Claim
283 words
A transfer device for withdrawing and transferring an item from a dispenser station containing a plurality of items to a receiving station comprising, (a) a frame, (b) rotor means mounted on said frame for rotation about a first axis, (c) at least one arm member mounted on said rotor means and projecting radially from said first axis, (d) a head pivotably mounted on each arm for movement about a secondary axis parallel to said first axis, said head having an outwardly directed transfer surface having a leading edge disposed in the direction of rotation thereof about said first axis and a trailing edge disposed in the opposite direction, said secondary axis being radially movable relative to said first axis in response to movement of said head between an extended position and a retracted position as said head moves past said dispenser station, (e) first guide means for causing said head to pivot about said secondary axis to angularly incline said head to a first position as it approaches said dispenser station in which the trailing edge is disposed radially outwardly of the leading edge whereby the trailing edge is the first portion of the head to engage the leading item at the dispenser station, said head being mounted to pivot about said secondary axis during its traverse through said dispenser station such that said outer surface is rocked about said secondary axis to bring said leading edge into engagement with the item to be transferred from said dispenser station, (f) means for securing an item to said outer surface of said head as it moves through said dispenser station to transfer the item by means of said head to said item receiving station.
Claim 11
Dependent Claim
283 words
A transfer device for withdrawing and transferring an item from a dispenser station containing a plurality of items to a receiving station comprising, (a) a frame, (b) rotor means mounted on said frame for rotation about a first axis, (c) at least one arm member mounted on said rotor means and projecting radially from said first axis, (d) a head pivotably mounted on each arm for movement about a secondary axis parallel to said first axis, said head having an outwardly directed transfer surface having a leading edge disposed in the direction of rotation thereof about said first axis and a trailing edge disposed in the opposite direction, said secondary axis being radially movable relative to said first axis in response to movement of said head between an extended position and a retracted position as said head moves past said dispenser station, (e) first guide means for causing said head to pivot about said secondary axis to angularly incline said head to a first position as it approaches said dispenser station in which the trailing edge is disposed radially outwardly of the leading edge whereby the trailing edge is the first portion of the head to engage the leading item at the dispenser station, said head being mounted to pivot about said secondary axis during its traverse through said dispenser station such that said outer surface is rocked about said secondary axis to bring said leading edge into engagement with the item to be transferred from said dispenser station, (f) means for securing an item to said outer surface of said head as it moves through said dispenser station to transfer the item by means of said head to said item receiving station.
