Automatic Four Head Pick And Place Type Screw Capping Machine
Next-Generation Rotary Capping Technology
The Harsiddh Automatic Four Head Pick and Place Screw Capping Machine (HBCS-120PP) is a market-leading solution designed for high-precision PET and glass bottle sealing. Unlike standard capping units, the “Pick and Place” mechanism ensures the cap is gripped firmly before being seated on the bottle, virtually eliminating cross-threading. It is a highly flexible workhorse, capable of handling round, square, and uniquely shaped containers with minimal format parts.
Reliable Operational Workflow
The machine delivers a synchronized, high-speed automated cycle for flawless sealing.
Sequence of Operation:
- In-feed & Indexing: Bottles are indexed into the rotary turret via a synchronized star wheel system protected by safety clutches.
- Pick & Place Cycle: The first CAM assembly picks the oriented cap from the chute; the second CAM perfectly places it onto the bottle neck.
- Precision Torquing: The magnetic hysteresis heads descend to apply pre-set torque, ensuring a hermetic seal.
- Automatic Monitoring: Sensors verify “No Bottle – No Cap” logic, while the orientation unit maintains a steady cap supply.
- Discharge: Successfully capped bottles are moved to the outfeed conveyor, with the system providing a qualified capping ratio of ≥99.8%.

Frequently Asked Questions
What is the production capacity of this Four Head model?
The Four Head rotary configuration is designed for medium-to-high speed production lines. Depending on the bottle diameter and cap type, this machine can achieve a consistent output of 70 to 100 bottles per minute. It is the ideal solution for manufacturers looking for higher precision than a linear capper but who do not require the massive volume of an 8-head system.
Can the machine handle specialty caps like CRC or Pump caps?
Yes. One of the primary reasons to choose a Pick and Place machine is its versatility. It is exceptionally well-suited for Child Resistant Closures (CRC), flip-top caps, and even trigger pumps. Because the head physically grips the cap, it can handle complex cap geometries that are difficult for standard machines to orient and seat correctly.
How does the machine ensure consistent torque for every bottle?
To ensure product safety and prevent leaks, each of the four capping heads is equipped with an Adjustable Magnetic Hysteresis Torque mechanism. This allows the operator to set a specific torque limit. Once the cap is tightened to the exact specification, the head "slips" to prevent over-tightening, ensuring every bottle is sealed with identical tension without damaging the plastic threads.
What are the key construction and safety features of the machine?
As a cGMP-compliant model, the machine is built for durability and sterile environments:
Materials: Main frame and all covers are made of SS 304, with all contact parts in stainless steel or food-grade engineering plastics.
Safety Enclosure: A full acrylic safety cabinet with interlock switches that immediately stop the machine if the doors are opened.
Smart Sensors: Includes "No Bottle – No Cap" and "Chute Full" sensors to prevent component wastage and ensure a smooth, automated workflow.
