High-speed roller feeder machines come in a plethora of specifications, boasting 39 standard options to cater to diverse needs. Among these, popular models include RF-105, RF-138, RF-1310, RF-3010, and more. However, for tailored requirements concerning material width and feed pitch, specialized machine models can be meticulously customized. Making the right choice amidst this array of options demands a thorough understanding of pertinent factors. Here’s an exhaustive breakdown to aid you in selecting the ideal high-speed roller feeder machine:

I. Understanding Roller Feeder Machine Specifications:

Delve into the parameter table of roller feeder machines to grasp crucial distinctions. The nomenclature RF denotes single-sided feeding, optimized for coil materials with a thickness exceeding 0.1mm. On the other hand, RFS indicates double-sided feeding, comprising two feeding mechanisms—one for feeding and the other for pulling. This configuration suits materials with a thickness of 0.1mm or below, or for handling short-length materials. The numerical values appended to these designations, such as 105 or 1310, denote the feeding width, corresponding to dimensions like 100mm or 130mm. Additionally, the trailing digit(s) signify the feeding length, also referred to as the feed pitch, of the roller feeder machine.

II. Key Considerations in Roller Feeder Machine Selection:

  1. Punch Press Specifications:
    • Evaluate the brand, model, and tonnage of the punch press to ensure compatibility.
    • Determine the direction of the punch press output shaft, classifying it as left, right, or front-facing, depending on its orientation relative to the observer. For traditional mechanical punch presses equipped with flywheels on both sides, the distance from the output shaft to the brake disc should exceed 50mm. If uncertain, furnish several actual photos of the punch press for accurate assessment.
  2. Material Characteristics:
    • Ascertain the width, thickness, and type of material intended for processing.
  3. Feed Pitch and Precision Requirements:
    • Define the desired length of each feed and the precision standards to be met.
  4. Feed Rate Optimization:
    • The feed rate per minute, especially in high-speed operations, is intricately linked to the feed pitch.
  5. Die and Worktable Specifications:
    • Consider the die height and presence of guide pins, along with the height, width, and thickness of the punch press worktable. Additionally, assess the diameter, length, and height of the punch press output shaft relative to the worktable surface for calculating the connecting rod length.

III. Exploring Special Accessories for Roller Feeder Machines:

  1. Feed Distance Fine Adjustment Device:
    • Tailored for RF-1310 models or punch presses exceeding 65T, this device facilitates precise adjustments in feed pitch within a small range (within 0.1mm), thereby optimizing operational efficiency.
  2. PU Wheels Installation:
    • Incorporating PU wheels sourced from Germany proves beneficial, especially for handling sensitive soft materials. These wheels ensure that no pressure marks or scratches mar the material surface during stamping operations.
  3. Pneumatic Relaxation Mechanism:
    • While the standard relaxation method for roller feeder machines involves mechanical rod-type mechanisms, installations incompatible with this structure can opt for pneumatic relaxation. This alternative employs cylinders and solenoid valves to achieve relaxation efficiently.

In conclusion, selecting the right high-speed roller feeder machine necessitates a meticulous evaluation of various parameters and considerations. By adhering to the guidelines outlined herein, you can make an informed decision that aligns with your operational requirements and optimizes productivity.
