Abstract

A machine (1000) for forming a blank assembly having a blank and a retaining web coupled to the blank includes a deck (1250) coupled to a frame (1002), and a blank transfer assembly (1200) coupled to the frame. The blank transfer assembly is configured to position the blank on the deck. The machine also includes a web transfer assembly (1700) coupled to the frame. The web transfer assembly includes a pick-up assembly (1730) moveable between a first end and a second end of the web transfer assembly. The pick-up assembly is configured to pick up the web proximate the first end and deposit the web proximate the second end in an at least partially overlying relationship with the blank positioned on the deck. A first compression member (1750) is configured to compress a coupling region of the web against the blank on the deck to form the blank assembly.

First claim

What is claimed is:

1. A machine for forming a container having a retaining web coupled to an interior of the container, said machine comprising:
a deck coupled to a frame;
a blank transfer assembly associated with said frame, said blank transfer assembly configured to extract a blank from a magazine, transfer the blank in a blank transfer direction X, and position the blank on said deck;
a web transfer assembly associated with said frame and extending from a first end to a second end in a horizontal direction Y perpendicular to the blank transfer direction X, said web transfer assembly comprising a pick-up assembly moveable between said first end and said second end in the horizontal direction Y, said pick-up assembly configured to transfer the web from proximate said first end and deposit the web proximate said second end in an at least partially overlying relationship with the blank positioned on said deck;
a mandrel wrapping section comprising a mandrel mounted to said frame, said mandrel having an external shape complementary to an internal shape of at least a portion of the container, said mandrel wrapping section configured to wrap at least a portion of the blank assembly around the mandrel to at least partially form the container; and
a forwarding assembly downstream of said blank transfer assembly in the blank transfer direction X, said forwarding assembly configured to transfer the blank assembly along said deck in the blank transfer direction X toward said mandrel wrapping section while said web transfer assembly moves from said second end back to said first end.

2. The machine in accordance with claim 1 , wherein said mandrel wrapping section further comprises:
a lateral presser arm movably coupled to said frame, said lateral presser arm positionable generally proximate a first side of said mandrel, said lateral presser arm configured to wrap a first portion of the blank assembly about said mandrel; and
a folding arm movably coupled to said frame, said folding arm positionable at least generally proximate a second side of the mandrel, said folding arm configured to wrap a second portion of the blank assembly about said mandrel.

3. The machine in accordance with claim 1 , wherein said web transfer assembly comprises a gantry operable for bi-directional translation between said first end and said second end of said web transfer assembly, said pick-up assembly being coupled to said gantry.

4. The machine in accordance with claim 3 , wherein said web transfer assembly further comprises a lift arm coupled to said gantry and operable for translation with respect to said gantry bi-directionally in a vertical Z direction, said lift arm extending from a first end to an opposite second end, said lift arm moveable between an extended position, wherein said first end of said lift arm is proximate to said gantry, and a retracted position, wherein said second end of said lift arm is proximate to said gantry, said second end of said lift arm being coupled to said pick-up assembly.

5. The machine in accordance with claim 4 , wherein said web transfer assembly further comprises a first servomechanism coupled proximate said first end of said web transfer assembly and a second servomechanism coupled proximate said second end of said web transfer assembly, each of said first and second servomechanisms operable for bi-directional rotation and coupled to a belt that extends from a first end to a second end, each of said belt first end and said belt second end being coupled to said lift arm proximate said lift arm second end, said belt being looped in a circuit from proximate said lift arm second end, around said second servomechanism, around said lift arm first end, around said first servomechanism, and back to proximate said lift arm second end, such that said lift arm is carried by said belt.

6. The machine in accordance with claim 1 , further comprising a first compression member configured to compress a coupling region of the web against the blank on said deck to form the blank assembly.

7. The machine in accordance with claim 6 , wherein said first compression member is coupled to said pick-up assembly, and wherein said machine further comprises a second compression member coupled to said frame, said second compression member being positioned to provide a compression surface against which said first compression member is operable to compress the coupling region of the web and the blank.

8. The machine in accordance with claim 7 , wherein said second compression member is operably coupled to at least one actuator operable to move said second compression member between a first position, in which said second compression member is positioned proximate the blank to provide the compression surface, and a second position, in which said second compression member is positioned out of a path travelled by the forwarding assembly configured to transfer the blank assembly along said deck.

9. The machine in accordance with claim 1 , wherein said mandrel wrapping section is configured to wrap at least a portion of the blank assembly around the mandrel such that a coupling region of the web is compressed against the blank to securely bond the coupling region of the web to the blank.

10. The machine in accordance with claim 1 , further comprising a web adhesive applicator associated with said frame, said web adhesive applicator being operable to apply an adhesive material to at least a portion of the coupling region of the web as said pick-up assembly carries the web between said first end and said second end of said web transfer assembly.

11. The machine in accordance with claim 1 , wherein the blank comprises a plurality of side panels, a plurality of bottom panels, and a fold line extending between the plurality of side panels and the plurality of bottom panels, the web transfer assembly configured to position the web on the blank such that a free edge of the web is proximate to the fold line and extends in a direction substantially parallel to the fold line, the web overlying at least a portion of at least four side panels of the plurality of side panels.
