Abstract
Abstract A feeder mechanism for a labelling machine to transfer gum from a gumming apparatus to labels at a label supply location, and then to convey the labels to a transfer means. The mechanism includes a feeder member which carries at least one label receiving element mounted on the feeder member by means of a pivot shaft. The feeder member is rotatably driven about an axis and bodily driven in a circular path about a central axis, the feeder member axis being eccentric to said central axis. The pivot shaft is parallel to the rotary axis of its associated feeder member, whereby the movement of the pivot shaft perpendicular to its axial direction describes a looped hypotrochoid. The orientation of each label receiving element about the axis of its pivot shaft is controlled in dependence on the orientation of the feeder member about its rotary axis.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
247 words
A feeder mechanism for a labelling machine which transfers gum from a gumming arrangement to labels at a label supply location and conveys labels from the label supply location to transfer means, the mechanism including a feeder member which carries at least one label receiving element, which is mounted on the feeder member by means of a pivot shaft, the feeder member being drivable about a rotary axis of the feeder member and bodily around a circular path about a central axis, the pivot axis of said pivot shaft being parallel to the rotary axis of the feeder member, whereby the pivot axis of said pivot shaft moves in a direction perpendicular to said pivot axis axial direction and describes a looped hypotrochoid, means being provided to control the orientation of said label receiving element about the axis of said pivot shaft in dependence on the orientation of the feeder member about the feeder member rotary axis, said orientation control means comprising: a cam plate for controlling the orientation of said label receiving element, said cam plate being mounted to undergo bodily movement around the circular path about said central axis with the feeder member and arranged non-rotatable relatively to the rotary axis of said feeder member, a cam follower on the pivot shaft of said label receiving element, said cam follower engaging said cam plate, whereby rotation of the feeder member about its rotary axis relative to the cam plate causes said pivot shaft to rock.
Claim 2
Dependent Claim
247 words
A feeder mechanism for a labelling machine which transfers gum from a gumming arrangement to labels at a label supply location and conveys labels from the label supply location to transfer means, the mechanism including a feeder member which carries at least one label receiving element, which is mounted on the feeder member by means of a pivot shaft, the feeder member being drivable about a rotary axis of the feeder member and bodily around a circular path about a central axis, the pivot axis of said pivot shaft being parallel to the rotary axis of the feeder member, whereby the pivot axis of said pivot shaft moves in a direction perpendicular to said pivot axis axial direction and describes a looped hypotrochoid, means being provided to control the orientation of said label receiving element about the axis of said pivot shaft in dependence on the orientation of the feeder member about the feeder member rotary axis, said orientation control means comprising: a cam plate for controlling the orientation of said label receiving element, said cam plate being mounted to undergo bodily movement around the circular path about said central axis with the feeder member and arranged non-rotatable relatively to the rotary axis of said feeder member, a cam follower on the pivot shaft of said label receiving element, said cam follower engaging said cam plate, whereby rotation of the feeder member about its rotary axis relative to the cam plate causes said pivot shaft to rock.
Claim 3
Dependent Claim
57 words
A feeder mechanism as claimed in claim 1, in which said label receiving surface is carried on the free end of a respective first radial arm rigid with the respective pivot shaft, and the cam follower is carried on a second radial arm rigid with the respective pivot shaft and engages a groove in the cam plate.
Claim 4
Dependent Claim
239 words
A feeder mechanism as claimed in claim 1, in which, to afford said feeder member rotary and bodily movement, said feeder member is mounted for free rotation on an eccentric portion of a rotary drive shaft and is provided with a pinion secured thereto, the rotary axis of said pinion being coaxial with said eccentric portion and said pinion meshing with a fixed internally toothed annulus mounted coaxial with the axis of the drive shaft, said cam plate being rotationally freely mounted on the eccentric portion of said drive shaft and including a pinion secured thereto and coaxial with said eccentric portion, said cam plate pinion engaging a first gear wheel which is coaxial with and rigidly connected to a second gear wheel by means of a gear shaft, the gear shaft being mounted for rotation about its axis in a radial extension of the drive shaft, the rotary axis of the gear shaft being parallel to and spaced from the rotary axis of the drive shaft, the second gear wheel meshing with a toothed ring coaxial with and fixed relatively to the annulus, the gearing ratio between the toothed ring and the second gear wheel being equal to that between the pinion of the cam plate and the first gear wheel, whereby, when the drive shaft rotates, the cam plate moves bodily with the feeder member, but maintains its orientation about the eccentric portion relatively to the annulus.
Claim 5
Dependent Claim
38 words
A feeder mechanism as claimed in claim 3, in which the drive shaft is provided with a counterweight to balance the masses of the radial extension, of the first and second gear wheels and of the gear shaft.
Claim 6
Dependent Claim
63 words
A feeder mechanism as claimed in claim 4, in which the counterweight includes an arm which extends between the pinion on the feeder member and the annulus, said counter weight arm carrying a circular cover which has a circular hole which slidingly engages a further circular cover fixed to and coaxial with the feeder member and through which said pivot shaft rotatably extends.
