This filling and packaging machine is designed to provide a continuous packaging cycle, volumetric dosing of bulk products (washing powder, bird feed, seeds, corn sticks) and their packaging in polymer single-layer or multilayer films (polypropylene, duplex, triplex).

The equipment consists of a vertical packaging machine and a volumetric dispenser with a belt or vibration feeder.

The equipment allows for dosing (packaging) of bulk products from 2 to 10 liters, and their packaging in large packages (bags, sacks).

Characteristics.

* Productivity depends on the dose volume, package length, and properties of the packaging material.

** To ensure the operation of the pneumatic drives of this packaging machine, a “compressor” is required (supplied separately).

Description of work.

The packaged product is poured through the neck of the storage bin onto the feeder*, with the help of which it is fed into the funnel of the tube of the sleeve-forming device. The packaging material with a sealed back seam and bottom is rolled up on the tube. At the same time, the bottom seam is clamped in the heating elements of the soldering unit.

* The feeder can be made in the form of a vibrating tray or a polyurethane conveyor belt (the belt is more suitable for fragile, hard-to-flow products; in other cases, a vibrating tray is used). The feeder is controlled by a control unit, which, by supplying power to an electric motor or an electromagnet, makes the conveyor belt rotate or creates vibrations in the vibrating tray, thereby moving the product from the hopper neck to the tube funnel.

Spilling through the funnel along the tube, the product fills the bottom of the package and the tube itself. Given the weight of the dose and the pressure created on the bottom seam, the heating elements remain compressed until the end of the dose delivery. This eliminates the pressure on the package seam and the possibility of its rupture.

Inside the tube there is a capacitive sensor that reacts to the filling of the tube. As soon as the product, filling the tube, approaches the set distance to the capacitive sensor, the latter sends a signal to the control unit.

The control unit stops the feeder (stops the power supply), unclamps the heating elements of the soldering unit and turns on the pulling of the packaging material. Given that the package is welded directly on the web of the packaging material, when it is pulled, the roll is unwound and the packaging material is rolled up, by means of a collar, into a sleeve around the tube. The pulling is done using an electric motor and belts to the length set by the operator.

After the end of the pull, the control unit again compresses the heating elements, fixing the packaging material, and presses the vertical welding element to the tube, starting the process of welding the seams. At the same time, the control unit activates the volumetric dispenser feeder, filling the package with products.

The soldering unit of the packaging machine uses the principle of constant heating and in one step simultaneously seals the top seam of the filled package, the bottom and side seams of the next package with the “Euroche” type of seam. At the same time, at the moment of welding, the filled package is separated by cutting the film with a mechanical serrated knife. The cut package falls on the floor, into a special container (box) or onto a discharge conveyor.

Peculiarities.

This packaging machine is ideal for packaging products that are convenient to sell in large packages (bags, sacks). Such products can be: washing powder, bird feed, seeds, corn sticks, animal fillers, sugar.

The machine is not suitable for packaging highly dusty products. It should be taken into account that due to the use of a volumetric dispenser, the model is not universal and has restrictions on changing the product being packaged.

It should be taken into account that the soldering unit of this packaging machine does not allow the use of polyethylene (PE) films for its operation.

The packaging machine requires floor placement and has restrictions on the width of the packaging film used and the height of the formed package, specified in the technical specifications.
