Fast acting belt plough

Application

The Fast Acting Belt Plough has two main functions within a baggage handling system: Sortation and Route Diverting.

Sortation — The Fast Acting Belt Plough can be used for outsorting single bags from a stream of bags. In this mode, the action is similar to that of a pusher with the blade arm moving in and out, completing one full cycle for each bag diverted. Typical examples of Fast Acting Belt Ploughs being used for sorting are in the outsorting of bags on screening lines, diverting bags

to make-up carousels or laterals, as part of sortation systems or to send individual bags to manual coding lines.

Route Diverting — Alternatively, the belt plough can be used to divert a whole stream of bags off-line. In this instance the plough arm will remain in the divert position for a duration of time, until all bags for divert have cleared. This mode will usually be used for fallback conditions or to divert streams of bags during route selection within a baggage handling system.

Application Benefits

  • Absorbs shock loading to drive when plough diverts baggage
  • Ensures smooth cycle action of diverter arm during high cyclic periods
  • Up to 1500 sorts per hour
  • Reduces shock loads in plough structure by use of T.D.C.  mechanics
  • Eliminates risk of plough arm over-run
  • Eliminates trap points
  • Reduces maintenance requirements
  • Eliminates trap point for bag straps etc. between plough arm and conveyor belt
  • Accommodates variations such as bed width, belt height, drive components etc.
  • Use of standard PLC technology enables clients handling / screening schemes to be complemented

Description

The Model 656A Fast Acting Belt Plough has been designed to handle and sort a wide range of products, with minimum impact to the bag during the plough divert operation. The unit has been designed to be used in conjunction with the Logan Teleflex range of Model 570 Belt and Queue conveyors and with Model 688 Horizontal Claim Conveyors.
The Model 656A Belt Plough is of modular design enabling the unit to be supplied to suit the customers specific needs. These include variations in conveyor width, mounting method and various types of outfeed e.g.  sort chute, gravity roller, petty wheel chute, powered belt conveyor etc.

General Construction

The motorised belt plough can be an independently floor mounted unit adjacent to the line conveyor for maximum stability, alternatively it can be fixed direct to the conveyor frame.

The arm of the plough is of steel box section construction with a slider bed surface over which the plough belt runs. The diverter belt runs between vertically orientated drive and end pulleys. Belt tensioning is achieved by adjusting the end pulley.

The drive and end pulleys are fitted with grease packed precision bearings. The drive pulley is mounted on an extended drive shaft, which is driven by a geared motor, through a V belt drive arrangement.

The drive for the diverting motion is an integral geared motor mounted to the underside of the support frame. The motor is a 0.75 kW T.E.F.C., 1440 rpm. In certain applications the divert action may be controlled through AC Inverter.

A machined drive flange is fixed to the output shaft of the gearbox, which in turn is connected through a link bar mechanism to the main pivoting shaft of the plough arm. In this way the rotary action of the drive gearbox is transferred into the linear motion of the plough arm. The drive flange completes 3600 of travel for one full plough cycle.

A proximity type electrical sensor will detect when the plough arm has reached the out position. When diverting multiple bags, this will be used to stop the plough in the out position. A second sensor will also indicate when the arm has returned to the home position, causing the arm to stop.
