Automated Lid System

The Automated Lid System can perform a variety of operations for different types of plastic lids, gaskets, spouts and various closures/fitments, depending on your requirements.  The automated lid system can perform the following installation and verification functions:
  • 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.

Gasket Installation

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.

Flame Treating

The flame treating station can be enabled or disabled according the type of lid being processed.

Gasket Detection

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.

Lid Orientation

The lid orientation station orients the cover.

Fitment Installation

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.

Leak Testing

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.

Lid Stacker

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.
