Description

• Vials stopping unit at the dosing station, composed of a sectioned star wheel equipped with an electro-mechanical stopping device.
  
• Vials moving unit composed of a conveyor belt and a picking up feeding screw for bunging operations. Dosing unit, composed of a support where stainless steel rotary piston syringes are placed.
  
• Bungs feeding unit, composed of a vibrating feeding bowl, a vibrating feeding chute and a separating star-wheel.
  
• Easily replaceable change parts with minimum setting time to accept different sizes of vials.
• All controls through Programmable Logic, Controller or optionally through electrical interlocks.

Operation
Vials coming from the infeed turntable, are carried by the conveyor belt towards the dosing unit. A sensor, placed at the machine inlet, controls its charge stopping the machine in case of low quantity of vials. Vials entering the dosing unit are stopped downstream by an alveolate star-wheel which guarantees the perfect alignment of each vial with the relevant filling needle. Vials exiting the filling station are conveyed towards the capping unit. A sensor, controls the right position of each vial to verify an eventual upset of the feeding screw due to the machine immediately. Bungs are charged in to a feeding bowl, placed above the bunging unitand by means of vibrating bowl, they reach the feeding star wheel which seperates and place them near the capping disc. Each suction pin on the capping disk will pick up thr bung by vacuum holding it during the rotation of the disc and until it is set vertically so as to plig the bung into each vial. The bunged vial will be transferred by the feeding screw towards the pressing unit where a wheel will press the bung completely onto the vial in order to guarantee it's perfect closure.
