Overview

Here is a full drum accumulation conveyor. The gravity rollers are pitched to allow 450 lb drums to flow freely. When a fork truck removes four full drums, a photo eye recognizes the vacancy and signals the drum escapement to release another group of four drums, (two from each lane), where they are cradled by the padded drum stops.

The third drum in line is held back by the air operated drum escapement which uses a set of steel pins in front and behind the drum. When the front pins lower to release a drum, the back pins raise up between the rollers behind it, holding back the second and remaining drums in accumulation. When a photo eye recognizes two full drums in each lane, the escapement is locked in place to hold back the line. This holding back reduces the line pressure, which allows the fork truck no resistance when lifting up four drums.

Description of Operation

Full drum accumulation conveyors can be built in single, double, or triple lane widths. This roller system was designed to handle 450 lb steel, fiber or poly drums.

  • Full drums are conveyed onto one of the lines of accumulation
  • When two drums are at the end of any lane, that lane activates an escapement
  • The escapement holds back all the remaining drums until the first two are removed
  • The fork truck will remove two drums from each of the twin lanes, (four drums total)
  • Once removed, a signal is sent for the escapement to release two more drums
  •  A photo eye sees the second drum and shuts down the escapement
  • The fork truck again removes four drums and the cycle repeats
