Abstract

Apparatus and methods for forming multiple different types of containers are disclosed. The apparatus (100) includes a number of magazines (1, 3), each magazine storing a different type of container blank (2, 4). There are further insert magazines (9, 10, 11, 12), each storing a different type of container insert suitable for use with at least one of the container types. The apparatus further includes a forming station (6) that selects a blank of one container type, forms the container from the blank, and, if required, inserts one of the container inserts. The apparatus is flexible as it may switch from manufacture of a first type of container to a second type of container without requiring physical modification, or any significant delay.

Figure 2: Is a plan view of the container assembly machine of Figure 1, with part of the punch actuating mechanism removed for clarity.

Figure 3: Is a front elevation of the container assembly machine of Figure 1.

Figure 4: Is an end elevation of the container assembly machine of Figure 1. 30O621578_1.DOC MH504835/1 Figure 5: Shows diagrammatically two possible options for a container tray of one possible embodiment of the invention and four possible side wall insert options.

Description of Preferred Embodiments Referring first to Figures 1 to 4, a container assembly machine according to one preferred embodiment of the present invention is generally referenced 100.

A first container blank magazine 1 for storing blanks 2 for a first type of cardboard container is provided on a first side 200 of the machine 100, and a second container blank magazine 3 for storing blanks 4 for a second type of cardboard container is provided on an opposite side 300 of the machine 100.

A conveyor means, in this case a chain conveyor 5, transports a required blank 2 or 4 from the respective magazine 1, 3 to a forming station, generally referenced 6.

The forming station 6 includes a punch 7 or forming plunger, and gluing apparatus, which form and glue the selected blank into a finished container 8.

The machine 100 is provided with four insert magazines 9, 10, 11, 12 for storing inserts (not shown). The inserts are preferably reinforcement panels for the walls of the container.

Each insert magazine 9,10,11, 12 may be provided with a different type of insert, but in a preferred embodiment pairs of magazines on opposite sides of the machine may be provided with substantially identical inserts, as is described further below.

If the type of container being assembled requires one or more inserts, then the appropriate magazine(s) 9, 10, 11, 12 moves forward to present an appropriate insert to the punch 7, and then retracts to a parked position. Magazines of this type are known to the art, particularly in the field of kiwifruit packing containers.

In a preferred embodiment the first container magazine 1 stores blanks 2 suitable for containers of a first type having a first height, and a first pair of insert magazines 9, 10, 300431760J arranged on opposite sides of the machine 100, contain suitable inserts for the first type of container.

The second container magazine 3 contains blanks 4 for a second type of container 5 having a second, lower, height, but substantially identical width and length dimension as the first type of container. A second pair of insert magazines 11, 12 are arranged substantially directly above said first pair of magazines 9, 10.

If the container is to be provided with one or more inserts from one or more of the 10 magazines 9-12, then the punch 7 varies its width so that the total width of the punch 7 and any inserts it is carrying is appropriate for forming the particular type of container to be formed. In a preferred embodiment the width of the punch 7 and any inserts it is carrying is substantially constant. In this way the width and length of the containers formed by the apparatus may be substantially identical regardless of the number of inserts which the 15 container has been provided with. The inserts are preferably glued or laminated to the side walls of the container as is known to the art.

Referring next to Figure 5, two possible container tray shapes 10a, 10b are shown along with four possible insert shapes 11 a-d.

One insert 11a may be a flat corrugated sheet board which will simply provide an increased vertical side wall strength of the container. A further option is for the insert 11 b having returns 12 at each end which will be secured along the end wall of the tray 10a or 10b ^ to increase side wall and corner strength.

A further alternative is insert 11c which is shown creased so as to form a triangulated corner post 13 and return which secured to the end wall of the tray will further increase the strength in the corners of the container and provide the container with improved rigidity and stackability.

A further option 11d is provided by horizontally folded sheet board which may incorporate a sliding lug feature 14 which will further increase the side wall load strength of the resultant container and the lugs 14 will provide for improved stackability with similar containers.

Typically the components 11 a-d may be of any suitable paper grammage which may be varied independently of the paper grammage used for the trays 10a, 10b as can the 300431760_1 MH504835/1 respective flute directions, and depending on the load strength required of the finished container in any particular application.

In this embodiment the container trays 10a, 10b have substantially identical dimensions, but different comer constructions. In a preferred embodiment the machine uses only substantially flat inserts 10a, with no returns running along the end wall of the tray. As is described above, the insert magazines may be provided with inserts of similar design but varying height.

No physical modification of the machine is required in the transition between manufacturing different types of container. If a different blank is required, then the blank is automatically taken from the appropriate magazine. If different insert is required, then the correct magazine moves forward to present the blank to the punch. The operator does not need to manually change any physical characteristic of the machine.

In another embodiment (not shown) a container forming machine may be provided with additional container blank magazines and/or additional insert magazines. Preferably the magazine(s) may be positioned in substantially vertical columns on either side of the machine so that the footprint of the machine is minimized.

Those skilled in the art will appreciate that the present invention provides a container forming machine which provides additional flexibility over those of the prior art. The machine may switch from manufacture of a first type of container to a second type of container without requiring any physical modification, or any significant delay.

This may allow, for example, a small run of an unusual type of container to be assembled automatically on the same machine as normally produces large volumes of a more common type of container.

In other embodiments the container assembly machine may automatically change the type of container being produced, including whether the container includes one or more inserts or not, depending on the characteristics of the particular product that specific container is intended to accommodate. In a preferred embodiment the container forming machine may be used in a meat packing plant and may produce an appropriate size and/or type of container for a particular piece of meat. 300431760_1 MH504835/1 Where in the foregoing description, reference has been made to specific components or integers of the invention having known equivalents then such equivalents are herein incorporated as if individually set forth.

Although this invention has been described by way of example and with reference to possible embodiments thereof, it is to be understood that modifications or improvements may be made thereto without departing from the scope of the invention as defined in the appended claims. 300431760J MH504835/1
