The Model 595ML Vertical Sortation Unit is made up of three moving belt conveyors mounted within a support frame. The conveyors can pitch up and down to change the conveyor route through the VSU. This enables it to split the baggage flow from one conveyor line into two separate conveyor lines. The switching action is precise and fast enough to reliably remove a single bag from a continuous stream of bags.

It can also be used in reverse to combine the baggage flow from two separate conveyor lines into one.
The Vertical Sortation Unit has been designed to handle a wide range of products and will operate without disrupting the baggage flow. As the VSU does not exert any external force on the bag as it is being diverted the risk of damage to that bag is minimised.

Two different variants of VSU are available:

Model 595ML (long) where the shallow conveyor angles throughout the VSU allow bags to be tracked on both the upper and lower conveyor routes
And.
Model 595MS (short) where bag ‘tracking’ is only possible through the upper conveyor route.

Typical applications:

• Separating an individual bag from a stream of bags.

• Dividing a stream of bags from one conveyor line onto two separate conveyor lines.

• Merging two conveyor lines into one.

Working examples include:

• Diverting a single ‘suspect’ bag within a screening system.

• Sorting bags to different make-up carousels.

• Load sharing bags between different x-ray screening machines.

• Re-routing the flow of bags in a fall back scenario.

Model 595ML Vertical Sortation Unit Specifications

General Description

Vertical Sortation Unit – Conveyor Construction
The Conveyor modules are constructed from fabricated, press formed, 2.5mm painted mild steel. They comprise of a formed bedplate bolted between two flanged side frames. The bedplate is reinforced by stiffeners across the width of the conveyor. The modules are mounted on appropriate supports to provide a rigid structure. Conveyor modules are either, dispatched fully assembled or in flat pack form, dependent on type or requirements from our works.
The head and tail pulleys are of a fully welded construction, machine turned for concentricity. All pulleys are mounted between external bearings which can be suitably adjusted to align the pulleys and provide easy access for routine maintenance. Snubber Rollers with less than 45o of belt wrap are fitted with internal "sealed for life" bearings. Typical pulley diameters are:

Head / Tail and Central Drive Pulley                         100mm O/D             40mm Bearing Dia
Snubber Roller                                                          76mm O/D               30mm Internal Bearing

Drive is imparted to the head/tail pulleys via shaft mounted helical geared motors. The geared motors are supplied with integral brakes for rapid stop/start functionality.

Vertical Sortation Unit – Main Drive
The pivoting motion is imparted to the conveyors via “connecting rods and rocker arms”. The connecting rods are positioned close to vertical and are fixed to the conveyor bed sections and rocker arms with “sealed for life” rose type bearings. The rocker arm shaft is supported at both ends by plummer block bearings and is connected to the main drive motor via a crank arm which is fixed to the helical bevel geared motor output shaft using a shrink disc adaptor.

The movement and positioning of the pivoting conveyors is controlled by a cam attached to the geared motor output shaft and proximity censors.

The Model 595MS Vertical Sortation Unit is made up of two moving and one fixed belt conveyors mounted within a support frame. The conveyors can pitch up and down to change the conveyor route through the VSU. This enables it to split the baggage flow from one conveyor line into two separate conveyor lines. The switching action is precise and fast enough to reliably remove a single bag from a continuous stream of bags.
