BOXFORMINGMECHANISM&METHOD
Background ofthe Invention
This invention relates to a mechanism and a method of erecting a box from a foldable sheet material, such as a paperboard blank.
The term "box" used herein is intended to include open ended sleeves and sleeves having one open end. Indeed, the invention is particularly useful for forming an insert that is a sleeve which has one open end to receive product which can then be received in some form of outer packaging.
Summary ofthe Invention
One aspect of the present invention provides a mechanism for erecting a box from a foldable sheet material, such as paperboard, which mechanism comprises a first conveyor for receiving and conveying successive box blanks in a first generally horizontal plane and a second conveyor for receiving partially erected box blanks from the first conveyor and for completing the box forming in a second generally horizontal plane displaced vertically from said first horizontal plane, and wherein the first conveyor includes an inclined run extending towards the second conveyor during which inclined run successive box blanks are partially erected by successive transverse folding means each of which cooperates with a box blank in the inclined run to fold the box blank so that it can be received and -further folded by further folding means provided by the second conveyor, drive means being provided so that the horizontal component of speed ofthe inclined run is synchronized with that ofthe second conveyor.

Another aspect of the invention provides a method of erecting a box from a foldable sheet material, such as paperboard, which method comprises delivering successive box blanks to a first conveyor and conveying said blanks in a generally horizontal plane to a second conveyor, causing the blanks in the first conveyor to move through an inclined run ofthe first conveyor and to be engaged by transverse folding means which cooperate with the inclined run to partially fold the box blanks therein, causing the partially folded box blanks to be delivered from the inclined run to said second conveyor displaced vertically from said first conveyor and completing the folding of the box blanks as they are received by the second conveyor, drive means being provided to cause a horizontal component of movement of conveying means of he inclined run and ofthe second conveyor to be synchronized.
Brief Description ofthe Drawings
A mechanism and method of erecting a box from a paperboard blank, embodying the invention, will now be described, by way of example only, with reference to the accompanying drawings, in which: -
Figure 1 is a perspective view of a mechanism according to the invention, as seen from above and to one side, and
Figure 2 is a schematic side view ofthe mechanism showing movement ofthe conveyors.
Detailed Description ofthe Preferred Embodiments
Referring to the drawings, the mechanism comprises three main modules; a first conveyor 10, a second conveyor 12 and an intermediate conveyor 14.
The first conveyor 10, which has a generally trapezoidal construction, comprises a pair of spaced endless conveyors 10a, 10b on which a series of spaced lugs 10c, lOd respectively is carried. The first conveyor has an upper working run 16 disposed in a generally horizontal plane, an inclined working run 18 and return runs 20 and 22 (Figure 2). The upper run 16 receives box blanks in flat form from a supply (not shown). In this particular embodiment, each box blank 'B' has a number of mutually foldable panels as follows: a base panel Bl, side wall panels B2, B3, a top panel B4 and end closure panels B5 and B6 respectively (Figure 1, upper run).
When a blank is received on the upper run it has panels Bl, B3 and B4 supported by a pair of fixed support rails 24, 26 disposed between conveyors 10a, 10b (Fig 1) whereas the end closure panels B5, B6 are supported by the spaced moving conveyors 10a, 10b and engaged by the conveyor lugs 10c, lOd.
In the inclined run the fixed support rails 24, 26 are progressively arcuate out of the plane containing the conveyors 10a, 10b in a direction towards conveyor 12. The second conveyor 12 has an endless series of upstanding lugs 28 which move from left to right, in a generally horizontal plane as seen in the drawings. Juxtaposed pairs of lugs, e.g., lugs 28a and 28b are adjustably spaced apart and provide a former into which partially erected box blanks from the inclined run 18 are inserted.
In order to effect positive transfer of partially erected box blanks from the inclined run 18 to the second conveyor 12, an intermediate transfer conveyor 14 is provided. The intermediate transfer conveyor comprises, an upright frame 30 which is disposed alongside the second conveyor adjacent the inclined run ofthe first conveyor 10. In construction, the intermediate transfer conveyor resembles an inverted open-faced arrowhead in which an endless conveyor 32 carries a series of flat plate transverse arms 34. The conveyor 32 and hence the transverse arms have a working run 32a, a retracting run 32b and a return run 32c and the transverse arms are sized so that at some point in the operation ofthe intermediate transfer conveyor, the transverse arms extend over the inclined run 18 and/or the second conveyor 12.
In operation of the mechanism as a whole, the first and second conveyors move in a clockwise motion whereas the intermediate transfer conveyor moves in an anti-clockwise direction so that the transverse arms interfere with the movement of box blanks. Each box blank is delivered to and conveyed by the lugs 10c, lOd ofthe upper run conveyors 10a, 10b into the inclined run 18 where it is first engaged by one ofthe transverse arms 34 at the upper end of the inclined run 18. The working run 32a of conveyor 14 is parallel to that of the inclined run 18 and moves at the same speed so that as the engaged transverse arm moves downwards and forwards the horizontal box blank is folded against the fixed supports 24, 26 into a generally L-shaped configuration. More specifically, each transverse arm 34 engages the base panel Bl and the end closure panels B6 of a blank. Thus, the upright limb of the L-shape comprises side panel B2 and top panel B4 whereas the horizontal limb of he L-shape comprises the remaining panels of the blank of which panels B3 (forwards) and B5 (sideways) extend beyond the engaging face ofthe transverse arm 34.
Whereas the rotational speeds of the conveyors 10 and 14 are matched so that successive transverse arms engage successive box blanks, the speeds of horizontal components of their inclined working runs 18 and 32a, respectively, are synchronized with the speed ofthe second conveyor 12.
In this way, each successive transverse arm is able to locate between successive juxtaposed pairs 28a, 28b of upright lugs ofthe second conveyor and in so doing the partially formed box blank is further folded as it is pushed downwardly into the space between the juxtaposed lugs to form a generally channel shape. Thus, base panel Bl overlies the conveyor 12, side wall panel B3 is disposed upright against the leading lug 28b and side wall panel B2 together with top panel B4 is disposed upright against the trailing lug 28a. During this folding operation, a fixed guide 36 located alongside conveyor 12 in the path of movement of end closure panels B5 causes those panels to be folded upwardly to close one end ofthe channel form ofthe box blank. At or about the completion of this folding sequence, the engaged transverse arm begins to retract from engagement between juxtaposed lugs 28a, 28b moving upwardly and forwardly in the retracting run 32b in which the horizontal component of speed of conveyor 30 is synchronized with that of conveyor 12.
In order to complete the folding operation to provide a fully formed insert, a rotatable folder (not shown) may be provided above conveyor 12 to knock down the top panel B4 ofthe blank to form a sleeve with one open end facing the intermediate transfer conveyor 14. Thereafter, successive inserts may be ejected from the mechanism by suitable means, for example, transversely reciprocal pushers (not shown) which may be cam guided in their operation, and the ejected inserts then filled with product for further processing.
