Claims
- 1. A labeling machine for applying labels to containers on a conveyor, the containers on the conveyor being a size that is selected from a plurality of container sizes in which one of the sizes in the plurality is defined as a mid-sized container, comprising a starwheel assembly having a hub and a starwheel member and means connecting said starwheel member to the hub such that said starwheel member can be rotatively adjusted relative to the hub, said starwheel member including peripheral cusps formed in the circumference of the starwheel member, said circumference establishing a diameter for said starwheel member and each of said cusps for receiving one of the containers therein, a table for supporting said starwheel assembly, a slot positioned in the table, a starwheel drive shaft having a vertical axis and extending upward through said slot and engaging the starwheel assembly for driving the starwheel assembly, a driving gear for engaging said starwheel drive shaft and driving said starwheel assembly, an alignment plate that is movable relative to said table and supporting and aligning said starwheel assembly with respect to said conveyor, and including a pivot member mounted to said table and supporting said alignment plate so that said alignment plate will pivot about the pivot member relative to said table wherein said pivot member is in alignment with said driving gear axis, wherein said starwheel drive shaft moves through said slot as the alignment plate pivots about the pivot member, and wherein the horizontal separation between the axis of the starwheel drive shaft and the driving gear axis remains the same as the alignment plate is pivoted to accommodate new container sizes, a clamp mechanism mounted on the surface for locking the alignment plate with starwheel assembly thereon in a predetermined position and a flange that is secured to the end of the starwheel drive shaft, an alignment pin mounted on the flange, a recess formed in the hub for receiving the alignment pin to assure repositioning of a starwheel assembly each time a starwheel assembly is replaced, and wherein said starwheel member is rotated relative to the hub to match starwheel timing to the labeling machine.
- 2. A labelling machine in accordance with claim 1, wherein said starwheel assembly is no more than five times the diameter of the mid-sized container that the machine is capable of labelling.
- 3. A labeling machine for applying labels to containers on a conveyor, the containers on the conveyor being a size that is selected from a plurality of container sizes in which one of the sizes in the plurality is defined as a mid-sized container comprising a starwheel assembly having a hub, first and second starwheel members and means connecting said starwheel members to the hub such that said starwheel members can be rotatively adjusted relative to the hub, said starwheel members including peripheral cusps formed in the circumference of the starwheel member, said circumference establishing a diameter for said starwheel members and each of said cusps for receiving one of the containers therein, a table for supporting said starwheel assembly, a slot positioned in the table, a starwheel drive shaft having a vertical axis and extending upward through said slot and engaging the starwheel assembly for driving the starwheel assembly, a driving gear for engaging said starwheel drive shaft and driving said starwheel assembly, an alignment plate that is movable relative to said table and supporting and aligning said starwheel assembly with respect to said conveyor, and including a pivot member mounted to said table and supporting said alignment plate so that said alignment plate will pivot about the pivot member relative to said table wherein said pivot member is in alignment with said driving gear axis, wherein said starwheel drive shaft moves through said slot as the alignment plate pivots about the pivot member, and wherein the horizontal separation between the axis of the starwheel drive shaft and the driving gear axis remains the same as the alignment plate is pivoted to accommodate new container sizes, a clamp mechanism mounted on the surface for locking the alignment plate with the starwheel assembly thereon in a predetermined position, and a flange that is secured to the end of the starwheel drive shaft, an alignment pin mounted on the flange, a recess formed in the hub for receiving the alignment pin to assure repositioning of a starwheel assembly each time a starwheel assembly is replaced, and wherein said starwheel members are rotated relative to the hub to match starwheel timing to the labeling machine.
- 4. A labelling machine according to claim 3, wherein said second starwheel member has at least one slot formed therein for adjusting the angular relation between said first and second starwheel members and said alignment means to match said starwheel members timing to the labelling machine and to establish an alignment and adjustment means that is integral with said coupled starwheel members.
