Abstract
Abstract A packaging machine for loading trays with delicate articles such as cakes or tarts comprises a first conveyor for conveying a stream of the articles to be loaded, a plate pivotally mounted at the end of a first conveyor to receive articles from the first conveyor, a stop above the plate to locate on the plate an article fed by the first conveyor, a pusher mounted above the plate and on the same side of the stop as the first conveyor, a second conveyor beneath the plate for conveying the tray to be loaded and a mechanism for moving the plate the stop and the pusher. In use the packaging machine is arranged so that articles from the first conveyor move in turn under the pusher and on to the plate where they are located by the stop, the plate is then tipped, the stop moved away from the article and the pusher moved downwards and away from the first conveyor to push the article on the plate down the plate past the stop and off the plate into a tray on the second conveyor. The plate, the stop andthe pusher are subsequently returned to their initial positions to enable the plate to receive a further article from the first conveyor. The machine is usually arranged to accommodate more than one lane of articles on the plate with one article from each lane located on the plate against the stop.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
212 words
A packaging machine for loading trays with articles comprising, a first conveyor means for conveying a stream of articles to be loaded, a plate for receiving articles from said first conveyor, means pivotally mounting said plate at the end of said first conveyor means, a stop to locate on said plate articles from said first conveyor means, means mounting said stop above said plate, a pusher to push articles present on said plate, means mounting said pusher above said plate and on the same side of said stop as said first conveyor means, a second conveyor means beneath said plate for conveying trays to be loaded, and a mechanism coupled to said plate, said stop and said pusher whereby actuation of said mechanism causes said plate to be tipped, said stop to be moved away from said article and said pusher to be moved downwards and away from said first conveyor means to push said article present on said plate down said plate past said stop and off said plate into said tray on said second conveyor means, further actuation of said mechanism causing subsequent return of said plate, said stop and said pusher to their initial positions to enable said plate to receive a further article from said first conveyor means.
Claim 2
Dependent Claim
212 words
A packaging machine for loading trays with articles comprising, a first conveyor means for conveying a stream of articles to be loaded, a plate for receiving articles from said first conveyor, means pivotally mounting said plate at the end of said first conveyor means, a stop to locate on said plate articles from said first conveyor means, means mounting said stop above said plate, a pusher to push articles present on said plate, means mounting said pusher above said plate and on the same side of said stop as said first conveyor means, a second conveyor means beneath said plate for conveying trays to be loaded, and a mechanism coupled to said plate, said stop and said pusher whereby actuation of said mechanism causes said plate to be tipped, said stop to be moved away from said article and said pusher to be moved downwards and away from said first conveyor means to push said article present on said plate down said plate past said stop and off said plate into said tray on said second conveyor means, further actuation of said mechanism causing subsequent return of said plate, said stop and said pusher to their initial positions to enable said plate to receive a further article from said first conveyor means.
Claim 3
Dependent Claim
66 words
The packaging machine of claim 1, wherein said plate includes stop means arranged so that when said plate is tipped said stop means face said first conveyor means and move into the path of said articles moving from said first conveyor means on to said plate whereby said stop means prevents said further article from moving on to said plate and returns to its initial position.
Claim 4
Dependent Claim
22 words
The packaging machine of claim 1, wherein said second conveyor means includes drive means capable of moving said second conveyor means continuously.
Claim 5
Dependent Claim
42 words
The packaging machine of claim 1, wherein said first conveyor means is adapted to convey more than one lane of said articles on to said plate with one article from each of said lanes being located on said plate by said stop.
Claim 6
Dependent Claim
45 words
The packaging machine of claim 3, wherein said mechanism for moving said plate, said stop and said pusher is driven from said drive and said second conveyor means whereby said actuation of said mechanism is maintained in synchronism with movement of said second conveyor means.
Claim 7
Dependent Claim
29 words
The packaging machine of claim 1 including override control means coupled to said mechanism to prevent said mechanism operating when a tray is absent from said second conveyor means.
Claim 8
Dependent Claim
29 words
The packaging machine of claim 1, including override control means coupled to said mechanism to prevent said mechanism operating when an article is absent from said first conveyor means.
Claim 9
Dependent Claim
79 words
A packaging apparatus comprising at least two machines in accordance with claim 1, arranged generally side by side, and translational means for moving said trays transversely from a first of said machines to a second of said machines, said mechanisms of said machines being operative whereby each of said trays receives a first layer of articles from said first machine and, after being moved transversely by said translational means, receives a second layer of articles from said second machine.
Claim 10
Dependent Claim
95 words
A packaging apparatus comprising at least two machines in accordance with claim 1, arranged generally side by side, and translational means for moving said trays transversely from a first of said machines to a second of said machines, said mechanisms of said machines being operative, whereby alternate ones of said trays receive a layer of articles from said first machine and, after said trays have been moved transversely by said translational means, the intervening ones of said trays, which are empty on leaving said first machine, receive a layer of articles from said second machine.
