Automatic forming, filling and sealing machines

Bagging machines

FFS 600 - 1200 with bottom-up filling system

The machines with bottom-up system for forming, filling and sealing plastic bags represent a cost-effective alternative in the area of FFS technology. The design of this series was kept simple and is characterised by minimal servicing effort. Due to their compact design, the machines only require minimal space. On the other hand the maximum capacity is 1,200 bags/hour. During this process the bags for the filling range from 10 to 50 kg are manufactured for tubular film with or without side pleats.

Applications

The machine is eminently suitable for bagging granular products such as plastic, sugar, fertiliser or caustic soda. The optimal bag form is achieved by compacting. Additional corner welding is available as an option.

Basic configuration

Roller unwinding system Each basic model with manual bag length and width regulation includes a supporting frame with four legs, the machine trim panels with four large doors and safety switches, the bag making station with roller holder and brake motor, the cutting unit and the bag base welding unit, a filling station with filling pipe and aspiration connection, a bag opening unit, a vacuum pump with filter and a safety guard in the welding zone. A sealing station with fan for weld seam cooling and a discharge conveyor round off the equipment on the basic model.

Additional configuration

Following additional equipment is available:
A unit for microperforation to vent the bag after filling, photocell marking detection, a steel frame with railings for weigher installation, rollers made of stainless steel as well as a pneumatic lifting unit for the reel of film. A discharge conveyor for the filled bags, a motorised 90° roller conveyor as well as corner welding round off the range.

Function description

Function 1: Unwinding the tubular film

Even if there are irregularities in the reel of film, a motor-driven rubber roller ensures optimal film tension.

Function 2: Bag base welding and bag length registration

After the pulse welding device has welded the bag base, the film is unwound until the previously selected length is reached. The cut is made after the unwinding process. The length is determined as standard using a pulse signal, optionally photocells are available for marked films.

Function 3: Filling and compacting

The empty bag is opened by suction cups and a fan. Dust is kept down in the welding zone by patented, pneumatically operated protective plates. During the filling process the bag is continuously supported from below by a vibrating grating that at the same time ensures optimal compaction of the product in the bag.

Function 4: Sealing

In the last work step, the pulse welding device seals the top edge of the bag. To remove as much air as possible from the bag, it is carefully stretched at the top edge by retaining clamps before it is sealed. Then the top seam is air-cooled and the filled bag is fed to the discharge roller conveyor.
