Multi Head Vial Capping Machine

The N.K industries have multitudinal range of multi head vial capping machines. Models like NKCS 150, NKCS-250, NKCS-350 and NKCS-450 are the different types of multi head capping machines provided by the N.K industries. Having a production rate of 120 to 400 vials per minute, they can seal 4, 6, 8 and even 12 heads at a time.

Multi Head Vial Capping Machine

Salient Features:

  • Total cGMP model.
  • Parts coming in contact with the vial / aluminum cap /exposed to the atmosphere are made out of stainless steel.
  • Single motor synchronizes conveyor, star wheels and platform turret and speed can be varied by the % speed pot on operating panel.
  • A Special clutch device is incorporated on the in feed worm and Star wheel system for stoppage of machine in the event, vial is over turned or over diameter.
  • A photo sensing device stops machine automatically in the event, there is no aluminum cap in delivery chute.
  • “No Stopper on Vial, Machine Stops System”, eliminates chances of sealing of vial without rubber stopper on sealing machine.
  • Spring loaded free spinning sealing rollers eliminates any damage to aluminum caps and also allows greater flexibility of variation in the container neck diameter.
  • Sealing Pressure can be varied to suit different gauges and sizes of aluminum caps.
  • Imported Gear Motor for Main drive.
  • A.C. Frequency drives for Main drive.
  • Digital Counter for counting number of sealed vials.
  • “No Seal in Chute, Machine Stops System”
  • “No Stopper on Vial before Sealing, Machine Stops System”.

Step by Step Machine working:

  • Load the Sufficient caps in Vibratory Bowl. The Vials are received from in feed of conveyor and moved to feed worm assy. through the slat conveyor. Feed worm will create space between two vials, before it is moved in in-feed star wheel.
  • Vibratory bowl feeds the cap into the cap chute continuously. If there is no sufficient caps in chute, NO-CAP sensor (Fiber optic Sensor) will give signal to control panel & Machine will Stop.
  • Now, at In feed star vial index further, take a cap from chute and transfer to Six station Main turret wheel. Six Head capping head & Turret rotate clockwise, move down the cam operated capping head one by one with cap die, hold the vial with cap, rotate further and sealing chuck will make a thread on cap & seal it properly.
  • After completion of cap sealing procedure at sixth station, capping head moves up and release the sealed vial. Now at out feed star plate, neat and cleaned capped vials will index further and transfer to discharge end of conveyor.
  • Finally, vial moves to the other on-line connected machine through the conveyor. Totalizer (Counter) will give information of Total No. of capped/sealed vials.
