Abstract

An apparatus is disclosed for applying tags with attached elastic anchor bands onto the tops of objects such as bottles in a high speed packaging application. The apparatus includes an infeed assembly for feeding a web, a conveyor assembly that receives a web and conveys it along a path in an upstream direction, a rotating selector wheel, a placement assembly, a pair of rotating jaw assembles, a vacuum cup of the selector wheel, and stretched elastic bands over the tops of respective bottles being conveyed along a path below the placing assembly. The elastic bands then snap onto the tops of their respective bottles to secure the tags to the bottles.

First claim

What is claimed is:

1. An apparatus comprising:
a rotatable hub;
an array of elongated members attached at one end to the rotatable hub, each elongated member having a cam follower projecting therefrom;
a rotatable wheel disposed adjacent the rotatable hub and being axially offset with respect thereto; and
an array of slots formed in the rotatable wheel and having distal ends adjacent the periphery of the wheel that are spaced further apart than opposite proximal ends of the slots;
the cam follower of each elongated member extending slidably into a respective one of the slots;
rotation of the hub and the wheel rotating the elongated members and moving the cam followers of each elongated member between proximal and distal ends of respective slots of the rotatable wheel to cause the elongated members to spread apart and bunch together as the elongated members are rotated by the hub.

2. The apparatus of claim 1 wherein the elongated members comprise a plurality of jaw assemblies that are positionable between a closed position and an open position.

3. The apparatus of claim 2 , wherein the cam follower is a first cam follower projecting from a first side of a respective jaw assembly of the plurality of jaw assemblies, each of the jaw assemblies further comprise a second cam follower extending from a second side of the jaw assemblies, the second side being opposite the first side.

4. The apparatus of claim 3 , further comprising a cam disc located adjacent to the plurality of jaw assemblies and having a cam track formed therein, the second cam follower of a respective jaw assembly is moveable in the cam track to open and close the jaw assemblies as they rotate about the hub.

5. The apparatus of claim 4 , wherein each jaw assembly further comprises a third cam follower extending from the second side of the jaw assemblies, the cam track of the cam disc is a first cam track for receiving the second cam follower, the cam disc comprises a second cam track for receiving the third cam follower.

6. The apparatus of claim 5 , further comprising at least one pin on each jaw assembly having an extended position and a retracted position, the third cam follower is moveable in the second cam track to position the at least one pin between the retracted position and the extended position as the jaw assemblies rotate about the hub.
