Rotary Monoblock Machine (RMM)
Product Overview
The Rotary Monoblock Machine (RMM) is a compact rotary monoblock platform integrating multiple packaging functions such as liquid filling and capping within a single unit. Deployed across a wide range of industries worldwide, the RMM delivers decades of dependable operation with straightforward operation and simplified maintenance.
Filling Principle
The RMM is fitted with a standard chain-elevated conveyor. Vials can be fed onto this conveyor manually, via a turntable or bulk feeder. A bulk feeder is strongly recommended for plastic vial applications. A presence sensor is mounted at the conveyor in-feed section.
Vials travel along the in-feed conveyor and transfer into the main starwheel, which indexes and locates containers for every processing station. While held by the starwheel, vials advance sequentially through integrated stations: filling, ball placement, plugging, cap placement and cap torquing. After completing all operations, vials exit the starwheel and move toward the conveyor discharge.
Conveyor length can be customized to match your factory layout and downstream machinery. A backup jam sensor is installed at the discharge end to guarantee smooth vial handling.
The RMM adopts positive displacement filling technology. Standard pump stroke is 50 mm with a maximum pump volume of 120 ml. Adjustable fill range covers 10% to 100% of pump capacity. Properly matched pistons and filling nozzles achieve volumetric accuracy of ±0.5%. Depending on machine configuration, double or triple dosing options are available to boost throughput or handle foamy liquids.
Plugging / Brush Placement
Plugs or brushes are supplied by an isolated vibratory bowl feeder mounted at the rear of the machine. Components travel along a short guide track to the pickup position. At this station, a pickup rod pushes the plug or brush upward from below and seats it into the spring-loaded collet of the plugging turret. The collet securely grips the part until it is inserted into the vial.
