Abstract
Abstract Apparatus for continuously feeding and controlling wraparound carrier for packaging a plurality of articles or containers is disclosed. The carriers are of the type having at least two draw-down and feed openings, one opening formed on each side thereof. Each carrier is initially partially wrapped about a plurality of containers. The carrier and container assemblies move along a guide track to the entrance of the carton draw-down (tightening) conveyor line of the present invention. The conveyor line comprises a pair of continuously moving timing chains having a plurality of draw-down lugs pivotally attached to and spaced apart along the chain. Each lug includes a tongue portion adapted for insertion through the openings to feed and to draw down the side walls, and also to control the positioning and movement of the containers. As the partially assembled carrier and containers enter between the moving chains, a cam follower portion of the lugs contact the camming rails, causing the lugs to sequentially pivot downwardly and into contact with the openings formed in the carrier. The carrier is moved along the conveyor line with the lugs engaging the containers through the carrier apertures for positive control. Downward pressure is applied by the lugs to the carrier, causing the carrier to be pulled down and tightened about the containers. The lugs are pivoted out of contact with the carrier as the carrier exits the conveyor line to complete the assembly process.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
129 words
Apparatus for applying a wraparound carrier to a plurality of containers or the like, said carrier being initially partially wrapped around said containers, said carrier including at least two opposed openings formed on opposite sides thereof, comprising: means for conveying said carrier and said containers; a plurality of lug means, pivotally attached to and spaced apart along said conveyor means, said lug means including tongue portions adapted for insertion into said openings formed in said carrier; and means for pivoting said lug means into contact with said carrier openings, whereby said carrier is tightened and secured about said containers by said pivoting lug means while being conveyed; said tongue portions of said lug means extending through said carrier openings sufficiently to separate and position said containers within said carrier.
Claim 2
Dependent Claim
129 words
Apparatus for applying a wraparound carrier to a plurality of containers or the like, said carrier being initially partially wrapped around said containers, said carrier including at least two opposed openings formed on opposite sides thereof, comprising: means for conveying said carrier and said containers; a plurality of lug means, pivotally attached to and spaced apart along said conveyor means, said lug means including tongue portions adapted for insertion into said openings formed in said carrier; and means for pivoting said lug means into contact with said carrier openings, whereby said carrier is tightened and secured about said containers by said pivoting lug means while being conveyed; said tongue portions of said lug means extending through said carrier openings sufficiently to separate and position said containers within said carrier.
Claim 3
Dependent Claim
27 words
The apparatus of claim 1 wherein said conveying means comprises a pair of movable members disposed on opposite sides of said carrier and mounting said lug means.
Claim 4
Dependent Claim
29 words
The apparatus of claim 1 wherein said tongue portion of said lug means includes vertical faces adapted to fit between and mate with said containers disposed in said carriers.
Claim 5
Dependent Claim
48 words
The apparatus of claim 1 wherein said pivoting means comprises a pair of camming rails disposed adjacent said conveyor means, said camming rails cooperating with said lug means to pivot said lug means downwardly when said lug means are carried past said camming rails by said conveyor means.
Claim 6
Dependent Claim
204 words
Apparatus for tightening and securing a wraparound carrier around a plurality of containers or the like, said carrier being initially partially wrapped about said containers to form a container carrier assembly, said carrier including means for securing said carrier together when tightened, said carrier further including at least two openings formed on opposite side walls thereof, said openings disposed substantially between said containers, comprising: means for guiding said partially wrapped container carrier assemblies; a pair of movable members arranged on opposite sides of said guide means for conveying said carrier and said containers; a plurality of lugs, pivotally attached to and spaced apart along said movable members, said lugs including a tongue portion adapted for insertion into said openings formed on said carrier, said tongue portion including vertical faces adapted to fit between said containers; and means for sequentially pivoting opposite pairs of said lugs downwardly into contact with said carrier openings to apply a steady downward pressure thereto, whereby said carrier is tightened and secured about said containers by said pivoting lugs while being conveyed, said tongue portions of said lugs extending through said carrier openings and said vertical tongue faces contacting said containers to control and position said containers within said carrier.
Claim 7
Dependent Claim
204 words
Apparatus for tightening and securing a wraparound carrier around a plurality of containers or the like, said carrier being initially partially wrapped about said containers to form a container carrier assembly, said carrier including means for securing said carrier together when tightened, said carrier further including at least two openings formed on opposite side walls thereof, said openings disposed substantially between said containers, comprising: means for guiding said partially wrapped container carrier assemblies; a pair of movable members arranged on opposite sides of said guide means for conveying said carrier and said containers; a plurality of lugs, pivotally attached to and spaced apart along said movable members, said lugs including a tongue portion adapted for insertion into said openings formed on said carrier, said tongue portion including vertical faces adapted to fit between said containers; and means for sequentially pivoting opposite pairs of said lugs downwardly into contact with said carrier openings to apply a steady downward pressure thereto, whereby said carrier is tightened and secured about said containers by said pivoting lugs while being conveyed, said tongue portions of said lugs extending through said carrier openings and said vertical tongue faces contacting said containers to control and position said containers within said carrier.
Claim 8
Dependent Claim
20 words
The apparatus of claim 5 wherein said pivoting means comprises a pair of linear cams, disposed adjacent said movable member.
Claim 9
Dependent Claim
31 words
The apparatus of claim 5 further including means for sequentially pivoting said lugs upwardly out of contact with said carrier apertures after said carrier is tightened and secured about said containers.
Claim 10
Dependent Claim
37 words
The apparatus of claim 7 wherein said lug pivoting means comprises compression springs disposed between said movable member and said lug for normally biasing said lugs in a vertical position with respect to said carrier side walls.
Claim 11
Dependent Claim
43 words
The apparatus of claim 5 wherein said guide means comprises a guide track disposed adjacent to and below said movable member for guiding a plurality of carrier and container assemblies into, through, and out of contact with said lugs on said movable member.
Claim 12
Dependent Claim
44 words
The apparatus of claim 9 further including pusher arms mounted to said movable member for spacing said plurality of carrier and container assemblies apart and accurately aligning said openings of said carriers with said pivoting lugs when said carrier enters between said movable belts.

The apparatus of claim 5 wherein each said movable member comprises a continuous chain.
Claim 14
Dependent Claim
29 words
The apparatus of claim 5 wherein the number of pairs of carrier draw-down lugs is one less than the number of containers disposed in a row in said carrier.
Claim 15
