Walthambury LogoSack Automation

Sack automation solutions from Morray Engineering and Walthambury reduce or eliminate the need to manually perform repetative tasks allowing for a more efficient deployment of labour.

Typically the combination of a Bagging Machine, Sack Placer, Sack Top Control System and either a fixed head stiching solution or heat sealer can allow a packing line to be run by a single operator.

Sack Top Control Systems

STC 8600 Sack Top Control System
STC 8600

The Morray STC8600 is offered for either net or gross weighing. The gross weighing option incorporates the trusted M425 weigher whereas the net weighing option requires the product to be weighed before being released into the bag. Both versions are fitted with a pneumatic bag clamp to hold the bag during the filling/ weighing process. Once the bag is filled it is lowered onto the conveyor where guide plates ensure that the top of the bag is held, formed and fully supported during the cycle from the bag clamp through the automatic infeed device. It is then delivered to the stitcher or heat sealer BEFORE being released.

STC 8900 High Speed Sack Top Control
STC 8600

The Morray STC8900 incorporates a pneumatic bag clamp to hold the bag during the filling process. Once the bag is filled it is lowered onto an Intralox conveyor, at the same time two spreader fingers descend with the sack and spread the sack top.

Two support arms then hold the sack top in the spread position and convey the filled sack foward to the stitcher or heat sealer before being released. The sack is supported at all times during this cycle to ensure a even, uniform seal every time.

Key Benefits

  • Up to 12 bags per minute depending on materialand bag type.

  • Ensures rapid, stable, upright transfer from the filling station to the sewing head or heat sealer for uniform, parallel, precision sealing every time.

  • Full pneumatic operation with PLC control for reliability.

  • Either L-R or R-L system directions available.

  • Can accommodate Newlong, Fischbein, Union Special and Reed Medway sewing heads or a heatsealer. All on either fixed height or adjustable mountings.

  • Adjustable guide boards for different bag specifications.

  • Operates with Intralox flat track conveyor.

  • Designed for use with a Morray WASP or WASP Lite sack placer, alternatively sacks can be manually placed.

  • Entire sack top control system mounted above the conveyor on one robust chassis leaving floor area clear.

  • Can be used with existing gross or net weighers.

  • Fitted with either a Newlong NP7A or DS9C head as standard.
