Operation
Robust construction with stainless steel contact parts and food grade
feeder belts gives smooth, fast and reliable sack conveying and closing
prior to sealing by stitcher or heat sealer.
A sack is placed on a spout clamp, either manually, or by any Pacepacker
Sackplacer, a pair of fingers then either stretch or reform the gussets
of the bag.
A pair of motorised Grip Arms then move around the bag and as it drops
from the clamp, they close on the bag, holding it in its formed state.
These arms then motor toward the sealer, releasing the bag into a twin
belt feeder. Even very unstable products can be accommodated with ease
as the bag top is held at all times prior to sealing, hence TBC – Total
Bag Control.
Control System
The stand-alone TBC control system utilises the latest PLC technology.
When used with a Pacepacker Sackplacer, the TBC PLC system becomes a
slave to the Sackplacers Master PLC. All motor drives are Inverter
controlled for perfect speed matching.
Packing Speeds
Packing speeds depend on many factors such as weigher speed, filling
time, conveyor speed etc. Typical speed for the TBC is 720 sacks per
hour or 12 bags per minute. However speeds in access of 900 bags per
hour or 15 bags per minute are possible.
Weigher Requirements
Works with almost any fully automatic net or gross weigher or volumetric
filler.
Sack Specification
Most commercial quality paper, plastic, WPP and laminated sacks are
acceptable, providing they are in good condition. Hessian sacks can be
used if they can be placed on the clamp.
Electrical Requirements
Standard: 415V, 50/60 Hertz 3 Phase + neutral, 10 Amp Supply.
Alternatives can be accommodated.
Air Requirements
Cool, clean, dry air at 6 bar (90 PSI) at 27Litres (0.5 CuFt) per cycle.
I.e. 6 cfm at 12 sacks per minute. Diameter 20mm (3/4”) supply pipe
minimum.
Shipping Specification
Depends on conveyor length and options fitted.
