DESCRIPTION:

BRIEF SUMMARY
This invention relates to a machine for forming cartons or crates and more particularly to a machine for forming cartons or crates from cardboard and particularly corrugated cardboard. The machine is preferably adapted to package goods, in the form of containers of milk or other liquid, into the crates during the carton forming process.
The crate formed by the machine of the invention has particular utility as a crate for transporting plastic milk bottles or cardboard milk containers but of course it may be used for other purposes.
Conventional crates, that is open top containers for transporting goods, in one form, are moulded of plastics material and consequently are relatively expensive to manufacture. The initial cost of manufacture is presumably offset by the fact that the crates are reusable but experience in the dairy industry, where such crates are used to transport milk containers, has shown that the ongoing costs of collecting, handling and washing the plastic crates as well as replacing crates which are lost, damaged or stolen, far outweigh the advantages of a reusable crate. Thus plastic milk crates are a very expensive component in the overall cost of transporting and storing milk or milk products.
The present applicants have addressed the problem of this high cost and have invented a disposable cardboard crate essentially for use in transporting and storing milk containers in the form of plastic bottles or cardboard cartons. The disposable cardboard crate is described in detail in applicants' earlier Australian patent application No. PH 8507 entitled "Improved Carton and Blank therefor.TM. and filed on 14th October, 1986.
In providing a disposable cardboard crate applicants were faced with the problem of providing a crate which can be readily formed and packaged, and which has the inherent stacking strength necessary for stacking a large number of packaged crates one on top of the other. To this end the crate described in applicants' aforementioned earlier application has inwardly extending horizontal ledges towards the top edge of the opposite ends of the crate and extending over the width of the crate. The ledges are provided as part of a triangular box structure or girder which contributes substantially to the rigidity of the carton or crate and the ledges provide a supporting structure for enabling a number of like crates to be stacked one on top of the other.
It will be evident to those skilled in the art that automatic formation and packaging of the aforementioned crate presents formidable problems. The problems are caused by the complexity of the crate caused by the box structure or girder and the fact that product, in the form of milk bottles or containers, cannot be packaged in the crate after formation thereof using an automatic "place packer.TM. machine because of interference with the box structure or girder. The latter problem occurs unless of course the crate is made larger than is necessary to contain the bottles or containers, which is undesirable because of inefficient space utilization and excessive movement of the containers within the crate.
It will be further evident that the conventional apparatus used in the dairy industry which requires a first machine to handle and wash the plastic crates and a second machine in the form of a `place packer` to package the goods therein is very expensive to initially purchase and install and is also expensive to maintain.
Accordingly, it is an object of this invention to provide an improved machine for forming crates from cardboard or like material, which machine also avoids or reduces one or more of the aforementioned problems.
The invention provides a machine for forming blanks of cardboard or like material into containers around goods to be packaged therein and including a first operating stage where a stack of said blanks are stored and sequentially fed to a forming stage, and a forming stage where said goods are loaded onto a said blank which is then formed into a said container around said goods, characterized in that, said conta
