Automated Lid System
- Installs gaskets and verifies gasket installation
- Installs spout and tint plug style closures, leak tests and push tests the installed closure
- Installs screw caps and level checks or leak tests the installed screw cap
- Installs vent plugs and leak tests the installed vent plug
In addition to the functions listed above, the automatic lid system’s infeed station can be built to include a de-nesting station, that receives stacked lids and separates each lid from the stack.
With all this in mind, we designed the automated lid system to be portable and to have a small foot print. We manufactured the machine from aluminum plates and made the machine movable with lockable casters. Further, to accommodate all the available functions, we made the program modular. Therefore, the user can enable and disable each station of the machine as required from the Siemens HMI.
The gaskets are partially placed on the lid by the operator before they enter the machine. From there, the lid enters the gasket installation station, where the rubber gasket is accurately inserted by means of an insertion wheel.
The flame treating station can be enabled or disabled according the type of lid being processed.
The gasket detection station confirms that the gasket is properly installed. It is able to detect double, missing, or folded-over gaskets. In the event a lid fails the gasket detection test, the succeeding stations will no longer process that lid.
The lid orientation station orients the cover.
Fitments are oriented and fed by means of a vibratory bowl feeder and small conveyor. A shuttle, or pick and place mechanism, places the fitments onto the bottom press and the top locator re-centres the cover. When a fitment is in the press and the lid is centred, the top press pushes down the cover and the fitment is pressed in from the bottom.
The leak testing station is where the lid is pressure tested for proper fitment installation. If a lid fails the leak test, it will not be stacked, but continue on to the reject bin.
The lid stacker stacks the lids to an adjustable number. Lids with installed spouts can be stacked 120 degrees offset to achieve a balanced stack. Upon completion, the stack is transferred to the stack accumulation table.

Lid In-feed Conveyors
Conveyors to move product from the mold or waiting stacks into the lid machine.
The stacks are conveyed up to the de-nesting station, where the lids are separated and then feed into the indexing conveyor of the lid automation.
