Abstract

A machine for forming a container from a blank includes a mandrel mounted to a frame. The mandrel includes a first side, an opposite second side, and an external shape complementary to an internal shape of at least a portion of the container. The machine also includes a first presser arm, a folding arm, and a second presser arm each coupled to the frame. The first presser arm is positionable generally proximate the first side of the mandrel and is configured to wrap a first portion of the blank about the mandrel. The folding arm is positionable at least generally proximate the second side of the mandrel and is configured to wrap a second portion of the blank about the mandrel. The second presser arm is disposed generally proximate the first presser arm and is configured to wrap a third portion of the blank about the mandrel.

First claim

What is claimed is:

1. A machine for forming a container from a blank, wherein the blank includes a reinforcement panel, a first side panel, a first end panel, a second side panel, a second end panel, and a glue panel connected in series along a plurality of parallel fold lines, said machine comprising:
a mandrel coupled to a frame said mandrel having a first side, an opposite second side, and an external shape complementary to an internal shape of at least a portion of the container;
a first presser arm associated with the frame, said first presser arm positionable generally proximate said first side of said mandrel, said first presser arm configured to press a first portion of the blank including at least the second end panel against said first side of said mandrel;
a folding arm associated with the frame, said folding arm positionable at least generally proximate said second side of said mandrel, said folding arm configured to wrap a second portion of the blank including at least the first end panel and the first side panel about said mandrel;
a second presser arm associated with the frame, said second presser arm disposed generally proximate said first presser arm, said second presser arm configured to press a third portion of the blank including at least the reinforcement panel against said first side of said mandrel such that that the reinforcement panel comes substantially into face-to-face contact with the first side of the mandrel to overlay the second end panel for coupling the reinforcement panel to the second end panel; and
a reinforcement panel presser assembly associated with the frame, said reinforcement panel presser assembly configured to press the reinforcement panel and the second end panel together against said first side of said mandrel to couple the reinforcement panel and the second end panel together to form the container from the blank.

2. The machine in accordance with claim 1 , further comprising:
a first lift mechanism coupled to said first presser arm and associated with the frame;
a second lift mechanism coupled to said folding arm and associated with the frame; and
a suspension mechanism coupled to said second presser arm and associated with the frame.

3. The machine in accordance with claim 1 , wherein said first presser arm is operatively coupled to a first servomechanism, said folding arm is operatively coupled to a second servomechanism, and said second presser arm is operatively coupled to a third servomechanism, said machine further comprising a control system in communication with said first servomechanism, said second servomechanism, and said third servomechanism, said control system is configured to transmit a signal to each of said first, second, and third servomechanisms to independently control movement of said first presser arm, said folding arm, and said second presser arm to wrap at least the first, second, and third portions of the blank about said mandrel to form the container.

4. The machine in accordance with claim 3 , further comprising:
a first lift mechanism coupled to said first presser arm and associated with the frame;
a second lift mechanism coupled to said folding arm and associated with the frame; and
a suspension mechanism coupled to said second presser arm and associated with the frame, wherein said first lift mechanism is operatively coupled to a fourth servomechanism, said second lift mechanism is operatively coupled to a fifth servomechanism, and said suspension mechanism is operatively coupled to a sixth servomechanism, wherein said control system is in communication with said fourth servomechanism, said fifth servomechanism, and said sixth servomechanism, said control system is further configured to transmit a signal to each of said fourth, fifth, and sixth servomechanisms to independently control movement of said first lift mechanism, said second lift mechanism, and said suspension mechanism to wrap at least the first, second, and third portions of the blank about said mandrel to form the container.

5. The machine in accordance with claim 1 , further comprising:
a glue panel folder assembly associated with the frame, said glue panel folder assembly configured to rotate the glue panel into contact with a third side of said mandrel extending between said first side and second side of said mandrel; and
a glue panel presser assembly associated with the frame, said glue panel presser assembly configured to press the glue panel and a portion of the first side panel together against said third side of said mandrel to form a manufacturing joint of the container.

6. The machine in accordance with claim 5 , wherein said glue panel folder assembly is movable between a first position configured to provide sufficient clearance from said mandrel to avoid interference with a wrapping of at least one of the second end panel and the reinforcement panel about said mandrel, and a second position configured to position the glue panel against said mandrel.

7. The machine in accordance with claim 1 , wherein said reinforcement panel presser assembly is operatively coupled to an eighth servomechanism, said machine further comprising a control system in communication with said eighth servomechanism, said control system is configured to transmit a signal to said eighth servomechanism to hold the reinforcement panel and the second end panel together against said first side of said mandrel for a predetermined time period such that the reinforcement panel and the second end panel are bonded together.

8. The machine in accordance with claim 1 , wherein the blank is configured to form a shelf-ready shipper display container with a removable shipping cover, the removable shipping cover includes a portion of the second end panel above a cut line in the second end panel, a glue area is defined on the portion of the second end panel above the cut line, said reinforcement panel presser assembly is configured to press the reinforcement panel and the portion of the second end panel above the cut line together against said first side of said mandrel to couple the reinforcement panel and the second end panel together.

9. The machine in accordance with claim 1 , wherein said reinforcement panel presser assembly is configured to move from a first position to a second position along a direction normal to said first and second sides of said mandrel to press the reinforcement panel and the second end panel against said first side of said mandrel.

10. A method for forming a container from a blank using a machine, wherein the blank includes a reinforcement panel, a first side panel, a first end panel, a second side panel, a second end panel, and a glue panel connected in series along a plurality of parallel fold lines, and where the machine includes a mandrel, a first presser arm positionable generally proximate a first side of the mandrel, a folding arm positionable at least generally proximate a second side of the mandrel opposite the first side, and a second presser arm disposed generally proximate the first presser arm, said method comprising:
positioning the blank under the mandrel;
pressing a first portion of the blank including at least the second end panel against the first side of the mandrel using the first presser arm;
wrapping a second portion of the blank including at least the first end panel and the first side panel about the mandrel using the folding arm;
wrapping a third portion of the blank including at least the reinforcement panel about the mandrel to overlay the second end panel against the first side of the mandrel using the second presser arm such that the reinforcement panel comes substantially into face-to-face contact with the first side of the mandrel;
pressing the
