Bag Placers & Heat sealing TBC

RMGroup have a range of bag placers and TBC units to further automate manual bagging systems.

Bag placers enables automation of semi-automatic filling and weighing systems for customers who have small production runs and have to frequently switch filling processes.

Polar Bag Placer

Principle of operation

Bags are placed on a belt which are fed into the bag placing unit. A sack is lifted from the pile by vacuum suction cups on an arm. Then, a chain on track transfers the bag towards a second set of arms with suction cups which pick up the bag from the open mouth. The bag is now ready for the paddle arms to pick the bag up and place on the bag clamp.

Packing Speeds
Packing speeds are very much dependant on varying factors such as product type, speed of weighing system, in-feed speed and bag type. Typical speed for the Polar is 600 sacks per hour or 10 bags per minute.

Sack Specification
The polar bag placer is suitable for plastic sacks (minimum of 120 micron) or paper bags. It is imperative that sacks are dry and free from static. Minimum sack size – 200mm x 350mm
Maximum sack size – 600mm x 1,000mm

Heat Sealing Total Bag Control

Designed by RMGroup all new total bag control complete with impulse sealing bars eliminate the requirement of a continuous heat sealer. Our system combines a standard total bag control unit and heat sealer in one. Its robust construction with stainless steel contact parts and feeder belts gives smooth, fast and reliable sack conveying and closing system.

Principle of operation

A sack is placed on a spout clamp, by the polar bag placer. A pair of fingers then either stretch or the gussets of the bag. The pair of motorised heat sealing arms then move around the bag and as it drops from the clamp, they close on the bag, holding it in its formed state. The bag is then conveyed towards the bag flattener whilst being sealed.

Sack Specification
The heat sealing total bag control is suitable for plastic sacks only.

Standard Total Bag Control

A sack is placed on a spout clamp, either manually, or by any 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.
