Abstract
Abstract A method and apparatus for accurately positioning a plurality of slotted boxes which are in a flat collapsed state, in a magazine of a box erector. The box erector handles and sets up the boxes into a position having an open top for subsequently receiving items therein while moving bottom closure flaps into a generally closed position. A laser unit is mounted adjacent a box supply loading magazine of the box erector and projects a beam of light against a box placed in the magazine. The magazine then is adjusted until the fixed light beam strikes a predetermined location on the box, preferably the end of a slot formed between adjacent major and minor flaps of the box. This light beam strike location correlates with a location at an unfold station of the erector which receives a bottom corner of the box. The accurate positioning of the box at the magazine ensures accurate movement and erection of the box by the remaining components of the erector as the box, and all subsequent boxes of the same size, are automatically moved through the erector.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
189 words
A method for handling and setting up slotted boxes in a magazine of a box erecting apparatus of the type in which a plurality of said boxes are maintained in the magazine in a generally flat collapsed state for subsequent removal and erection into an unfolded assembled position by the erecting apparatus, said method comprises the steps of: placing a collapsed box in the magazine adapted to hold a plurality of said collapsed boxes, said box having two pairs of bottom closure flaps with a slot being formed between each pair of adjacent flaps; projecting a fixed visible light beam onto the box in the magazine; adjusting the position of the box until the fixed light beam strikes the box at an end of one of the slots at a junction of a pair of said flaps, which end corresponds to a bottom corner of the box when said box is erected; and then placing a plurality of the collapsed boxes in the magazine in the same orientation as said collapsed box after said box has been adjusted, for subsequent removal and erection of said boxes by said apparatus.
Claim 2
Independent Claim
189 words
A method for handling and setting up slotted boxes in a magazine of a box erecting apparatus of the type in which a plurality of said boxes are maintained in the magazine in a generally flat collapsed state for subsequent removal and erection into an unfolded assembled position by the erecting apparatus, said method comprises the steps of: placing a collapsed box in the magazine adapted to hold a plurality of said collapsed boxes, said box having two pairs of bottom closure flaps with a slot being formed between each pair of adjacent flaps; projecting a fixed visible light beam onto the box in the magazine; adjusting the position of the box until the fixed light beam strikes the box at an end of one of the slots at a junction of a pair of said flaps, which end corresponds to a bottom corner of the box when said box is erected; and then placing a plurality of the collapsed boxes in the magazine in the same orientation as said collapsed box after said box has been adjusted, for subsequent removal and erection of said boxes by said apparatus.
Claim 3
Dependent Claim
38 words
The method as defined in claim 1 including the step of directing the beam of light toward said end of said one slot on a front surface of a collapsed box at a discharge end of the magazine.
Claim 4
Dependent Claim
38 words
The method as defined in claim 1 including the step of directing the beam of light toward said end of said one slot on a rear surface of a collapsed box at a discharge end of the magazine.
Claim 5
Dependent Claim
36 words
The method as defined in claim 1 including the steps of pulling a collapsed box from the magazine; and then moving said pulled box to an unfolded station, while said box remains in a collapsed state.
Claim 6
Dependent Claim
47 words
The method as defined in claim 4 including the steps of unfolding the collapsed box at the unfold station into an open state; then moving said open box to a flap closure station; and then moving the flaps into a folded state with respect to each other.
Claim 7
Dependent Claim
23 words
The method as defined in claim 1 in which the light beam is a beam of red light emitted by a laser unit.
Claim 8
Dependent Claim
44 words
The method as defined in claim 1 in which the step of adjusting the position of the box includes moving the magazine both vertically and horizontally until said fixed light beam strikes said box at the end of said one slot on said box.
Claim 9
Dependent Claim
138 words
In combination, a slotted box formed by sides, two of which sides have a first pair of opposed bottom flaps connected thereto and two other sides which have a second pair of opposed flaps connected thereto for closing a bottom of the box, said adjacent flaps being separated by slots; and an apparatus for handling and erecting said boxes; said apparatus including: a magazine for receiving said box in a flat collapsed condition; fixed light source means for directing a visible beam of light toward said box in the magazine; and means for vertically and horizontally adjusting the position of said magazine and box received therein until the visible beam of light strikes the box at an end of one of the slots, which end corresponds to a bottom corner of said box when erected in said apparatus.
Claim 10
Dependent Claim
138 words
In combination, a slotted box formed by sides, two of which sides have a first pair of opposed bottom flaps connected thereto and two other sides which have a second pair of opposed flaps connected thereto for closing a bottom of the box, said adjacent flaps being separated by slots; and an apparatus for handling and erecting said boxes; said apparatus including: a magazine for receiving said box in a flat collapsed condition; fixed light source means for directing a visible beam of light toward said box in the magazine; and means for vertically and horizontally adjusting the position of said magazine and box received therein until the visible beam of light strikes the box at an end of one of the slots, which end corresponds to a bottom corner of said box when erected in said apparatus.
Claim 11
Dependent Claim
41 words
The combination as defined in claim 8 including first picker means for pulling the collapsed box out of the magazine; and first carriage means for moving the first picker means and pulled box from adjacent the magazine to an unfold station.
Claim 12
Dependent Claim

The combination as defined in claim 9 including second picker means at the unfold station for moving the collapsed box into an unfolded open position in cooperation with the first picker means.
Claim 13
Dependent Claim
39 words
The combination as defined in claim 10 including closure means for folding the flaps into a folded position to close a bottom of the box; and second carriage means for moving the unfolded open box to said closure means.
Claim 14

Claim 15
Dependent Claim
52 words
The combination as defined in claim 12 in which the magazine has a discharge end and a supply end; and in which the laser unit is mounted beneath the magazine and between said supply and discharge ends whereby the beam of light is direct toward a rear surface of said collapsed box.
Claim 16
Dependent Claim
50 words
The combination as defined in claim 12 in which the magazine has a discharge end and a supply end; and in which the laser unit is mounted forward of the discharge end of the magazine whereby the beam of light is directed toward a front surface of a collapsed box.
