DA 20 BIO – Packaging machine for small bags from 1 kg to 5 kg
for low production rates

FIN

DA 20 BIO ENCAPSULED, WITH DOSER AND STITCHING LINE

MAIN DRIVE UNIT

• mechanical cam type;
• grease-lubricated.

BAG MAGAZINE

• quick and easy to adjust, from the smallest to the biggest bag size;
• convenient to refill;
• 300/350 bags capacity;
• empty magazine alarm;
• can be refilled without having to stop the machine.

4-STATION CAROUSEL

• operated by mechanical cams;
• die-cast aluminum head, completely enclosed to guarantee hygiene and prevent dust from reaching the mechanisms (1);
• bag presence sensor (no bag - no filling);
• top edge of the bag supported by suction cups connected to the vacuum pump (2);
• dust extraction hoods (2);
• vibration table (2).

Bags rest on a vibrating table.
The vibration stroke can be adjusted to meet different needs.

STITCHED CLOSURE

After packaging, bags are evacuated from the carousel for closure by stitching.
The packaging machine is combined with the model LCS stitching system and is available in the following version:
• CR: seam with fold.

CONTROL BOARD

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.

ELECTRICAL PANEL

The electrical panel is integrated on board the machine, completely wired, and easily accessible.
The operational control is with PLC logic.
The standard degree of protection is IP 54.

VERTICAL SCREW DOSER FOR POWDERS

• container in AISI 304 stainless steel;
• motor-driven internal agitator;
• speed control system with encoder;
• speed control with frequency changer (inverter);
• pneumatically operated shut-off gates;
• dust extraction intake at discharge outlet;
• rapid change for the dosing screw (quick coupling).

WEIGHT CHECKING, FEEDBACK, AND OUT-OF-TOLERANCE BAG REJECTION

The application of the “weight checking” system provides continual monitoring of the weights obtained, plus:

• rejection of bags with weight outside the tolerance range;
• display of current weight;
• setting and recall of different sizes (up to 9);
• display of the last 20 weights checked for each doser;
• average weight calculation;
• display of counts of in tolerance, minor out of tolerance, and rejected major out-of-tolerance bags;
• feedback to the doser for automatic adjustment of weight in case of deviation.

The system comprises:

• weighing belt (on load cell);
• analogue digital hardware system;
• dedicated software program.

The system is installed at the line exit, immediately after the closing area.

METAL DETECTOR

Main constituent parts:

• motorized belt conveyor appropriately designed to prevent magnetic interference with the detector coil (conveyor at least 2250 mm long, in relation to the bag passage opening);
• detection system;
• digital electronic terminal installed on board the detector coil structure;
• standard bag passage opening 300 (h) x 700 (l) mm (larger or smaller sizes are available);
• Ethernet interface.

General characteristics:

• automatic self-calibration function cyclically programmable from a keyboard;
• scanning field adjustment;
• automatic compensation of the sensitivity level in relation to the percentage change in product humidity;
• event log displayable on the local control panel (or transferable via Ethernet) including:
  - current date
  - last reset date
  - total bags inspected
  - total bags rejected;
• protection class IP 69;
• MD detection system + terminal constructed in AISI 304 stainless steel;
• visual and acoustic alarm for out-of-tolerance bags;
• remote connection for bag rejector.

DATE / CODE STAMPING SYSTEM

For basic marking (date or code), an “ink pad” stamping system is available.

Inkjet date / code printing units are also available.

LABELLING UNIT

After closing, an adhesive label can be applied on the bag to guarantee its closure.

The equipment comprises:

• reel holder (label support);
• device which separates the label and rewinds the backing film;
• pneumatic label applicator.

SIZE CHANGE

Packaging machines can be used for multiple bag sizes. In this case, the machine will have to be equipped with the related size change accessories.

Size change procedures are simple mechanical operations which can be performed by unskilled workers trained for this task.

Estimated size change time:
1.5 hours approx.

SIFTER (FOR FLOUR SAFETY)

This machine guarantees a 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.
