DA 80 – Packaging machine for small bags from 500 g to 5 kg
for high production rates
DA 80 packaging machines:
a wide range of solutions for small bags filling.
High performance and minimal maintenance are guaranteed by the fully mechanical operation achieved with cams, by the absence of vacuum pumps, and by the minimization of pneumatic components.
The front paneling, equipped with sliding doors, provides wide accessibility for maintenance, an expanded visual for surveillance, and a high level of safety in compliance with the standards.
The packaging process is linear and occurs in 14 consecutive stations where the bags, two by two, are:
- retrieved from the magazines;
- opened and filled;
- vibrated;
- closed.

TYPES OF CLOSURE
The filling system produces perfectly squared flat-bottomed, self-standing bags with fin and flat-top (brick) closure.
FIN
Welded
Stitched
Glued
FLAT-TOP (BRICK)
APPLICATIONS
The range of options and equipments available meets the most varied applications and needs:
- dosing or weighing;
- electronic weight checking with automatic feedback to the dosing system, rejection of the out-of-tolerance bag and weight logging;
- closure using glue, stitching or welding;
- labelling;
- bundling and heat-shrinking;
- online process monitoring and telephone support.
GENERAL CHARACTERISTICS
FRAME
The frame is constructed of tubular profiles; a sturdy "framework" within which the electrical and pneumatic cables run.
Thanks to the design carried out with computer simulation, a perfect balance between weight and rigidity has been achieved.
Dust collection areas are minimized yet accessible, in accordance with sanitation regulations.
MAIN DRIVE UNIT
- With large-diameter mechanical cams to ensure low rpm and therefore total absence of vibration and wear;
- Grease lubrication.
Cam assembly is performed on a bench to ensure perfect mechanical assembly.
The 4 assemblies that house all the kinematic mechanisms (cams and levers) are easily removable from the machine frame, facilitating maintenance when and where required.
BAG MAGAZINES (2 IN PARALLEL)
- quick and easy to adjust;
- convenient to refill;
- 450 bags capacity per magazine*;
- empty magazine alarm;
- can be refilled without having to stop the machine.
* In the DA 80/5 version there is only one bag magazine with a capacity of 400 bags.
BAG PICK-UP
The bags are picked up with the aid of extractor hoods (1) (total absence of filters, vacuum pumps, and suction cups) and opened with mechanical grippers (2) that hold them under the filling area.
The "bag presence" sensor stops filling if the bag is incorrectly presented.

VIBRATION TABLE
The bags rest on a large vibrating table (2300 mm long).
The vibration amplitude and frequency can be adjusted to meet different needs.
HOT-MELT GLUE CLOSURE
The filled and vibrated bags are conveyed, step-by-step, in a straight line through the glue closing station, where the following actions are performed in sequence:
- bag mouth forming (3) (4);
- trimming of the top edge (5);
- double folding of the edge (5);
- application of hot-melt glue by a rotary disc distributor (6) (7);
- as an alternative, for special requirements and applications, a spray module for hot-melt glue application is installed (8);
- pressing of the top (in the case of flat-top closure) to create a compact, properly squared bag.
Rotary disc gluer (standard version)
Spray gluer (optional version)
WELDED CLOSURE
As an alternative to glue closure, welding can be used (on bags in weldable material).
The welder, with heated bars controlled by thermostat or with on-off operation, is pneumatically operated.
Welding temperature and time are fully adjustable parameters.
ELECTRICAL PANEL
The electrical panel is integrated on board the machine, completely wired and widely accessible.
The packaging speed is controlled by a frequency changer (inverter), while the operational control is provided by a PLC.
Alarm messages and cyclical maintenance alerts will be shown on a display.
The standard degree of protection is IP 54.
CONTROL BOARD
The control panel is assembled within reach of the operator.
The push-button control board is structured to ensure user-friendly operation of the packaging line.
An operator interface is also provided to allow access to the machine settings and alarm messages.
ACCESSORIES - DOSING
VERTICAL SCREW DOSER FOR POWDERS

Estimated size change time:
3.5 hours approx.
DA 80 SIZE CHANGE
3.5 h approx.
SIFTER (FOR FLOUR SAFETY)
This machine guarantees perfect product separation by means of the centrifugal motion of the machine and its internal drum.
The drum can be either in stainless steel or nylon depending on the required granulometry and flow rate, and the various models can be equipped with paddles or shakers.
