Overview

This document provides technical instructions and specifications for a screw blowing pipe system integrated with a vibratory bowl feeder, primarily used in automotive electronics, home appliances, instrumentation, and IC electronics manufacturing.

1. Screw Blowing Pipe Specifications

• Reserved turning space dimensions are indicated but partially obscured.
• Length-to-diameter (L/D) ratios for the pipe range between approximately 1.25 and 2.0, with specific limits provided for different configurations.
• Diameter constraints for the pipe are specified but partially unclear.

2. Vibratory Bowl Feeder Features

• Application fields include automotive electronics, home appliances, instrumentation, and IC electronics.
• Feeding speed can reach up to several hundred pieces per minute, enhancing production efficiency.
• Equipped with a standard material shortage sensor that provides early warnings to prevent feeding interruptions and ensure continuous production.
• Low screw jamming rate, especially for spring flat washer screws, with rates below approximately 0.1% per minute.
• Low noise operation with sound levels under 70 dB, improving the workshop environment.
• Use of integrally molded special polymer trays that offer strong wear resistance, reduce friction and noise.

3. Product Configuration and Nomenclature

• Configurations include Medium (M) and Standard (S).
• Product codes follow a structured algebra indicating screw type (S for screw, H for hexagon head), module type (VB for vibratory bowl), blow screw tube length, product category (FD for screw feeder), capacity, number of channels (C1 for single, C2 for dual), and base support (F).

4. Technical Parameters

• Power source: Voltage and frequency ranges are specified (e.g., DC 24V, guest supply voltage 220V/50Hz).
• Rated power consumption and air consumption values are provided but partially obscured.
• Inlet pipe diameter and noise levels (measured at over 1 meter distance) are given as reference values.
• Additional features include I/O lines, power cords, and blow screw tube lengths.

5. Product System Components and Interfaces

• Includes silo interface, flip down button, lower/up reset, RS232 and USB power connectors.
• Screw divider and duplex magnetic transparent top cover for easy monitoring.
• Shortage sensor and power switch box integrated.
• LCD lattice display and reserved opening space above the upper cover with specified opening directions.

6. Product Advantages

• High efficiency and uninterrupted feeding process ensured by sensors and stable equipment design.
• Low noise and low screw jamming rates improve production environment and reliability.
• Wear-resistant polymer trays reduce maintenance and operational noise.

7. Application Scope and Suitable Screw Types

• Suitable for standard and combination screws with specified maximum diameters and lengths.
• Supports various screw types including standard screws and hexagon head screws.
