Turning for Cylindrical Package Components
Precision turning operations for cylindrical package components require tight dimensional control, often within ±0.05mm tolerances, while maintaining surface finishes of Ra 0.8μm or better. These specifications must be achieved across varying material properties and geometries, from threaded closures to telescoping mechanisms, where even minor variations can affect sealing and rotation performance.
The fundamental challenge lies in balancing cutting parameters and tool geometry to achieve dimensional accuracy while maintaining production speeds that meet packaging industry throughput requirements.
This page brings together solutions from recent research—including optimized threading operations for refillable containers, precision turning for telescopic rod mechanisms, and surface finishing techniques for rotating closure systems. These and other approaches focus on achieving consistent quality in high-volume production environments while minimizing material waste and tooling costs.
1. Container with Tapered Subdivision Compartment and Selective Closure Mechanism for Portioning
JS SQUARE CO LTD, 2023
Container with a subdivision feature that allows accurate portioning of contents when discharging. The container has a main storage compartment and a subdivision compartment connected below it. The subdivision compartment tapers inward towards the bottom. When the container is upright, contents flow into the tapered subdivision section. When turned, the contents are discharged through an outlet in the subdivision compartment. This ensures a fixed amount is discharged each time. A closure at the connection between the main compartment and subdivision compartment closes off the connection when the container is upright to prevent spillage. When turned, it opens to connect the compartments.
2. Rotary Packaging System with Continuous Product Residue Removal via Rotating Discharge Tube
HAVER & BOECKER OHG, 2022
Fast and efficient emptying of rotary packaging systems like vertical form fill seal machines without stopping the operation. The system has a continuous emptying method where the machine keeps running while a specialized emptying device removes product residue from the silos. The device has a rotating discharge tube with openings near the filling spouts. It connects to a station and rotates with the machine to sweep out the leftover product. This allows complete or high-speed emptying without starting/stopping the system.
3. Brush-Based Sterile Packaging Orientation Device with Coordinated Pivoting and Rotating Mechanism
B, 2021
A device for orienting sterile packaging, like injection syringe tubs, to prepare them for cutting without using vacuum or pressure pumps. The device has a brush station with horizontally rotating brushes that contact the packaging edges to fold and tighten them. The brushes can pivot and rotate coordinately to grip both sides of the edge. This uniform tension improves folding/tightening. A control device coordinates brush motion. The brushes have rollers with flexible bristles to grip without drawing in the whole bag.
4. Automated Article Extraction and Orientation System with Vacuum Suction and Rotating Mechanism
HANWHA CORP, 2021
Automated system for extracting articles from a packaging box with an open top and arranging them in a specific direction for transportation. The system has conveyors to move the boxes, a fixation device to hold the box in place, a vacuum suction device to extract the articles, and a rotating device to reorient articles with different-sized ends. The system detects the article orientation and rotates them before loading onto a transport conveyor. This allows extracting articles from a box with open top, aligning them, and transporting multiple items in a consistent direction.
5. Toner Container with Integrated Cap and Rotatable Internal Protrusion for Clog Prevention
KYOCERA DOCUMENT SOLUTIONS CO LTD, 2019
A toner container for image forming apparatus like printers that reduces toner clogging in the cap and avoids increasing parts count compared to separate discharge fins. The container has an integrated cap that protrudes radially outward. A movable protrusion inside the container body rotates as the body turns. When the protrusion passes above the cap's discharge port, it helps loosen toner inside the cap. This prevents toner from packing in the cap's narrow neck. The container body rotates to transport toner while the cap stops. The protrusion's rotation path is outside the sealing member between cap and body.
6. Apparatus and Method for Overprint Removal from Cylindrical Metal Packaging Using Rotational Abrasion and Water Spray
CZACHOROWSKI BARTOSZ JAKUB, 2019
A method and apparatus for removing overprints from cylindrical metal packaging like beverage cans without damaging them. The method involves rotating the can at high speed while an abrasive element contacts the overprinted surface. Water is sprayed on the surface to assist removal. The can is held between a rotating holder and a stationary roller. The abrasive element rotates parallel to the can's axis.
