Pail Sizers

Pail sizer units are highly effective at improving molding cycle time.  Martin Automated Systems manufactures pail sizers for both square and round pails. The pail sizers are water-cooled, and the expanding jaws are machined from hard anodized aluminum or optional heat treated stainless tool steel and use Turcite bearings.

Operation Summary

• Pails are conveyed up to two pin stops, positioning the pail directly under the expanding mandrel,
• The pail is then pushed up onto the expanding mandrel
• Two additional pin stops are actuated, preventing upstream pails from entering the system,
• After the pre-set expansion hold time, the core is collapsed and the pail is lowered to the conveyor,
• The pin-stops under the expanding mandrel retract allowing the pail to exit.  Then the hold back pin-stops retract, which allows the next upstream pail to be processed. 
• While the hold back stop is retracted a second hold back stop is extended, thus preventing other upstream pails from entering.

Features

• The expanding mandrel is manufactured from hard anodized aluminum or optional heat-treated mould steel (Stavax)
• Water cooled
• The core is expanded by means of a wedge, driven by an 8” diameter air cylinder.
• The amount of expansion is controlled by an adjustable barrel style stop
• Timing parameters of the machine are settable by means of a small HMI
• A Siemens PLC is used to control the unit
• Guarding to be compliant with OSHA
