Sealing Machines: RHO II

Sealing of pre-fabricated, peelable membranes into cardboard bodies
up to 150 cans/minute

Technology:

• Pressure and heat are used to seal the pre-fabricated, deep-drawn membrane into the cardboard body.
  
• This makes for an hermetically tight and extremely reliable seal with peelable membranes.
  
• The pre-fabricated membrane and the cardboard body have to be made from sealable materials.
• Modular system with turret principle.
  
• More than 180° turret rotation is available for sealing.
  
• The cardboard bodies are carefully transported.
  
• The cardboard bodies are spaced by a driven dosing-star with its own monitoring unit and an infeed-worm to match the tool stations.
• The pre-fabricated membranes are fed into the machine by transport-belt or air conveyor.
  
• The membranes are reliably transferred to the sealing stations by mechanical guides.
  
• The membranes are synchronously positioned to the cardboard bodies.
• Each sealing tool is fitted with two (one inner and one outer) controlled heating systems.
  
• This reliably ensures the sealing temperatures remain constant during the production process.
• Quality check by video monitoring with pneumatic ejection of faulty cans.(Option)
• Central height adjustment by PLC for different can-heights.
• The sealing-tools are fitted with a quick-change system.
  
• Easy changeover to other can-sizes.
  
• The working stations are easily accessible for service.
  
• The machine is fitted with high-quality components, thus ensuring low maintenance.
• The switchbox is located on top of the machine, saving space.
• The flexible modular system can be adapted to different technological operations and output requirements. E.g., a module is added to apply a plastic cover to the sealed can end.
  
• Monitoring of the cover is included.
• The machine corresponds to all international safety regulations.
  
• The machine features transparent covers with locked doors.
  
• Height-adjustable covers at discharge according to the can height.
  
• PLC – control with service advice.
• In case non-circular bodies are processed, the cardboard bodies are calibrated in the first module and sealing is carried out in the second module.
