Pop-Up Transfer
The pop-up transfer is a device used to move material on or off of a conveyor line. It transfers loads quickly while minimizing interruption of material flow. It reduces the amount of floor space required because it resides within the conveyor frame. Pop-up transfers can be used in various types of conveyors including belt, roller and chain conveyor as well as sorters. There are several types available to handle different types of loads from pallets to individual totes or cartons.
Product Type
  • Transfer device.
Product Components
  • Photo-eye sensing device.

Integration Options
Technology Overview
  • Benefits
    • Eliminates curves.
    • More efficient use of space.
    • Change conveying direction – either left or right from main line.
    • Ability to maintain or change load orientation depending on application requirements.
    • Gentle load handling.
Operations
  • Load passes photo eye signaling solenoid that the load is in position above transfer device.
  • Solenoid releases a volume of compressed air to cylinder or air spring, which raises transfer and load above conveying surface.
  • An optional pneumatic stop can be used to ensure proper positioning of load.
  • Transfer device moves load off conveying surface, in direction of device orientation (usually right angle) and on to secondary conveyor line.
  • Transfer device drops below conveying surface and load proceeds along secondary conveyor line.
Applications
  • Low capacity and low speed conveyor lines with few transfers.
  • Larger distance between transfers.
