TS-TR100 Intralogistics Belt Curves

Gramac Quartz Belt Curves: designed to smoothly change the travel direction of products within high speed handling systems.

Gramac Quartz is the division of Amber Industries Ltd which has specialised for over 30 years in the manufacture of Belt Curves for many different applications and combinations of load duty, arc and width formats. Its TS-TR100 range of belt curves have been purposely designed for incorporation into the most demanding a handling environments.

Standard TS-TR100 Product Design Features

Friction Drive for Maximum Operating Life / Minimum Maintenance and Noise: All Gramac Quartz Belt Curves use the ‘Friction Drive’ method whereby friction between the belt and a drive pulley provides the motive force for the belt. This method has three clear advantages over the positive mechanical drive method. They are:

  • The tensile stresses in the belt are more evenly distributed across the width of the belt thus extending the life of the belt and avoiding stress concentrations causing tears
  • Noise levels are kept to a minimum because of the absence moving metal parts such as chains and transmission belts/chains. The maximum running noise level for any Gramac
  • Quartz Belt is 65 dbA at 1000mm, i.e. they are very quiet items of equipment
  • Maintenance routines are minimal and no lubrication is required throughout the operating life of the bend unlike with positive mechanical drives where chains have to be regularly lubricated

Minimal and Easy Maintenance: Gramac Quartz Belt Curves are designed to minimise and simplify maintenance operations without the use of any special tools. The heaviest item on a belt curves is normally the geared motor unit which can weigh up to 35Kg depending on size. Belt and pulley replacement is usually carried out from the inside radius of the bend but can be done from the top if there is insufficient space. All periodic inspection and maintenance routines are explained in detail in the O & M manual issued with every belt curves.

Newly introduced design features of the TS-TR100 Belt Curves are:

  • Split top section which reduces the manual handling risk and the time consumed replacing the belt. Less physical exertion is required to open the frame so that one person can change a belt
  • Quick release under guards
  • Incorporation of 150mm wide viewing window to allow condition of belt guide bearing to be observed

In summary Gramac Quartz friction drive Belt Curves offer highly reliable low cost of ownership over time.

TS-TR100 Design Features

Robust Construction:

The Gramac Quartz Belt ’s robust design consists of a rigid frame fabricated from steel section and plate rolled and formed to give the desired angle and radius. A stiffened 3mm thick steel slider bed is mounted within the frame to support the belt.

TS-TR100 Robust Construction

Tapered End Pulleys:

Supported at each end of the curved frame by ‘life greased’ ball bearing units fixed to it are tapered conical pulleys manufactured in high density polypropylene on a steel shaft. These two pulleys can be adjusted in the horizontal plane by tensioning devices to provide the correct amount of tension in the belt. Each pulley is removable independently from the side of the belt curves.

Maximum Power Transmission:

The drive pulley is lagged with a non-slip, highly wear resilient and heat resistant material which positively grips the underside of the belt. The taper of the pulley allows it to engage with the belt across its full width thus ensuring maximum power transmission from a suitably sized geared motor unit fitted to the shaft of the drive pulley.

Drive Type:

Shaft mounted motor gearboxes from multiple suppliers can be accommodated. Gramac Quartz standard supply is from the SEW Eurodrive range (IP54, IE2 compliant). Other types of drive unit can be readily fitted including the latest high efficiency units, e.g. SEW Movigear and Siemens Simogear.

Drive Position:

The preferred position for the drive unit is horizontally mounted on the outer radius at the discharge end of the belt curves. On some larger radius curves it is possible to vertically mount the geared motor on the inner radius.

Travel Direction & Speed:

Travel direction of the belt can be clockwise or anti-clockwise at speeds of up to 150M/min as measured at the centre line. Variable speed drives can be supplied on request.

Belt Type:

All belt curves are fitted with endless belts with only the minimum number of vulcanised spliced joints. The belt fabric used is two ply non mono polyester backed, black PVC top (smooth or gripface surface as required), low friction, low noise, flame retardant to ISO 340.

Sidewalls:

Removable sheet steel sidewalls can be fabricated to a max height of 450mm above the top of belt and a distance between of 900mm. They can be supplied with brackets and slots for mounting photo sensors (PEC’s) etc. for controlling material flow. Sidewalls can have a powder coated finish in a selected colour or a BZP finish.

Supports:

Can be ‘H’ type floor supports made from RHS, outriggers for low level positions, side mounted brackets for suspending from above using threaded rods or special supports can be designed to suit specific situations. Floor supports can be fitted with either anti-vibration footpads with +/- 50mm adjustment or with locking wheels/castors if required to be mobile.

Finish & Colour:

Belt curves can be powder coated in any standard RAL colour.

Fully Guarded:

All Belt Curves are supplied with safety guards fitted to eliminate trap points and prevent inadvertent access to moving parts such as the pulley ends and roller guide bearings. These guards are designed to be lightweight for easy removal for maintenance. Removable sheet steel underside guarding is provided as standard.
