F.lli Sacchi Linea insacco e pallettizzazione “Smart

The plant comprises the following components:
 Platform with a vibrated base for the bin support; this platform is protected by perimeter railings and is accessed via a ship-type ladder;
 Empty bag magazine; the supply of empty bags is performed manually by the operator. The exact position of the bags is secured by adjustable side guides; a sensor located under the stack of bags signals when the pile is depleted;
 On the structure of the empty bag magazine, pneumatic cylinders are installed for gripping the bag, opening its mouth, and inserting it onto the product dosing spout. The bags are handled by a series of suction cups. The pneumatic control panel QP1 is also mounted on the supporting structure of the magazine;
 The dosing spout is supported by 3 load cells; at the outlet, a bucket-type gate valve driven by two pneumatic cylinders is installed. Next to it, two additional cylinders with hooks at the ends are used for tensioning the bag mouth.
 The bag is clamped along its longer side by two jaws that hold it after filling and guide it to the sewing machine. Movement is achieved by geared motor units and wheels sliding on chrome-plated rods. At this stage, the bag rests on a motorized conveyor belt for transfer; this belt is also raised via a pneumatic cylinder so that the bag rests gently upon filling completion; the height of this belt can be adjusted manually using a handwheel acting on four jacks, to adapt the belt height to the bag type.
 Once inserted into the sewing machine, the bag is stitched and the thread cut; still resting on the conveyor, the bag reaches the overturning station—there, it is held by two jaws, rotated 90°, and finally released so as to be parallel to the conveyor.
 The next belt features, in its initial part, a series of square rollers for bag straightening, followed by a conveyor belt for forward movement;
 Lastly, there is the roller conveyor where the bag is picked up by the robot; this conveyor is stopped by a photocell when the bag reaches the end of the roller line;

 The robot gripper is of the comb type and is equipped with a translation cylinder to discharge the bag and two cylinders operating a plate to lock the bag during handling prior to discharge.
 Two boxes containing the solenoid valves and vacuum units are installed on the plant;
 An electrical control panel manages the entire plant; the operator panel and weighing module are installed on it;
 The robot is managed by its own control panel with a dedicated operator interface;
