Stopper Bowl Feeder

Product Specifications

Technical details and manufacturing context for Stopper Bowl Feeder

Definition

The Stopper Bowl Feeder is a component used in stoppering stations within the pharmaceutical and packaging industries. Its primary function is to automatically orient, align, and feed stoppers (plugs, caps, or closures) from bulk storage into the correct position for insertion into containers. The feeder ensures a consistent presentation of stoppers at the required rate, which is critical for maintaining the efficiency and reliability of the stoppering process.

The feeder operates on the principle of vibratory conveyance. Stoppers are loaded in bulk into a vibrating bowl. Controlled vibrations cause the stoppers to travel along a spiral track. Tooling on the track, such as wiper blades, grooves, or air jets, rejects incorrectly oriented stoppers back into the bowl, while correctly oriented stoppers are guided to an exit track that delivers them sequentially to the pick-and-place or insertion mechanism of the stoppering station.

Key specifications include a feed rate of 60–120 pieces per minute, a bowl diameter of 300–800 mm, and a bowl capacity of 5–20 liters. Orientation accuracy is ±0.5 mm. The feeder operates on 220–240 V AC (single phase, 50/60 Hz) with a power consumption of 0.2–0.5 kW. It is designed for an operating temperature range of 0–40 °C and relative humidity up to 85% (non-condensing). The ingress protection rating is IP54 per IEC 60529. Contact parts are made of AISI 304 stainless steel (per ASTM A240) for corrosion resistance and cleanability. The weight ranges from 50–150 kg, and the footprint varies from 600×600×800 mm to 1000×1000×1200 mm (L×W×H).

These values are reference ranges and must be verified for the specific model and application. Always confirm model-specific parameters and compliance with applicable standards with the legal manufacturer or supplier before procurement or use.

Working Principle

Stoppers are loaded in bulk into a vibrating bowl. Controlled vibrations cause the stoppers to travel along a spiral track. Tooling on the track (e.g., wiper blades, grooves, air jets) rejects incorrectly oriented stoppers back into the bowl, while correctly oriented stoppers are guided to an exit track that delivers them sequentially to the pick-and-place or insertion mechanism of the stoppering station.

Frequently Asked Questions

What is the typical feed rate of a Stopper Bowl Feeder?

The reference feed rate range is 60–120 pieces per minute, depending on stopper size and bowl diameter. The actual rate for a specific model must be confirmed with the manufacturer.

What materials are used for contact parts?

Contact parts are typically made of AISI 304 stainless steel, which provides corrosion resistance and cleanability. Other materials like polyurethane or rubber may be used for liners or dampers. Verify material specifications for your application.

What is the ingress protection rating?

The reference ingress protection rating is IP54 per IEC 60529, suitable for typical pharmaceutical environments. Confirm the rating for the specific model.

How does the feeder ensure correct stopper orientation?

The feeder uses a vibrating bowl and spiral track with tooling such as wiper blades, grooves, or air jets to reject incorrectly oriented stoppers. Correctly oriented stoppers are guided to the exit track. Orientation accuracy is ±0.5 mm as a reference.
