Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
111 words
A banding apparatus comprising: a source of endless bands, gripping means comprising a base member having a central axis, a plurality of fingers mounted about and extending generally parallel to said axis and movable radially inward toward said axis and radially outward from said central axis for simultaneously gripping and expanding a band to encircle an article, first means for moving said fingers radially inwardly toward said axis for receiving a band, second means for moving said fingers radially outwardly for gripping said band, and transport means for transporting said gripping means from a position at said source of endless bands to a position of encircling an article with said band.
Claim 2
Dependent Claim
111 words
A banding apparatus comprising: a source of endless bands, gripping means comprising a base member having a central axis, a plurality of fingers mounted about and extending generally parallel to said axis and movable radially inward toward said axis and radially outward from said central axis for simultaneously gripping and expanding a band to encircle an article, first means for moving said fingers radially inwardly toward said axis for receiving a band, second means for moving said fingers radially outwardly for gripping said band, and transport means for transporting said gripping means from a position at said source of endless bands to a position of encircling an article with said band.
Claim 3
Dependent Claim
17 words
The banding apparatus of claim 1 wherein said first means for moving said fingers comprises cam means.
Claim 4
Dependent Claim
35 words
The banding apparatus of claim 2 wherein said cam means comprises a rotatable cam rotatable about said central axis for camming said fingers toward said axis, and a fixed cam for actuating said rotatable cam.
Claim 5
Dependent Claim
56 words
The banding apparatus of claim 3 including a plurality of said gripping means mounted on and carried by an endless chain, conveyor means adjacent said chain for conveying articles to a position for receiving a band so that said gripping means pick up bands from said source and places said bands on articles on said conveyor.
Claim 6
Dependent Claim
22 words
The banding apparatus of claim 4 wherein said endless chain is disposed above said conveyor, and articles on said conveyor are bottles.
Claim 7
Dependent Claim
19 words
The banding apparatus of claim 4 including band ejecting means for forcing bands from said fingers onto said articles.
Claim 8
Dependent Claim
41 words
The banding apparatus of claim 6 wherein said band ejecting means comprises a plunger extending along said central axis and having means for engaging a band on said fingers, and cam means for engaging and forcing said plunger along said axis.
Claim 9
Dependent Claim
57 words
The banding apparatus of claim 3 wherein said transport means includes a pair of spaced apart sprockets mounted for rotation about generally horizontal axes, an endless chain mounted on said sprockets and carrying said gripping means from said position for receiving a band from said source and to said position of encircling an article with said band.
Claim 10
Dependent Claim
34 words
The banding apparatus of claim 8 wherein said gripping is fixed in its relationship with respect to said endless chain and is positioned so that said fingers extend radially outward from said endless chain.
Claim 11
Dependent Claim
69 words
The banding apparatus of claim 8 wherein said source of endless bands comprises a band dispensing means positioned above one of said sprockets and said fixed cam means is positioned adjacent said one sprocket for camming said fingers radially inwardly toward said axis to the innermost position of said fingers at said band dispenses, said fingers being substantially vertically oriented at said band dispenser for receiving a band therefrom.
Claim 12
Dependent Claim
52 words
The banding apparatus of claim 10 including band ejection means comprising a plunger extending along said central axis and having means for engaging a band on said fingers, and cam means for engaging and forcing said plunger along said axis for engaging and forcing a band off the ends of said fingers.
Claim 13
Dependent Claim
61 words
The banding apparatus of claim 11 comprising a plurality of said gripping means mounted on said endless chain, and conveyor means disposed below said endless chain for conveying articles to a position for receiving a band so that said gripping means positions a band on said articles on said conveyor when said fingers are oriented in a generally vertically downward direction.
