The filling and packaging machine, model AF-50-OM, is designed to ensure a continuous cycle of filling (volumetric method) of free-flowing products (seeds, nuts, buckwheat, rice, sugar) and packing them in polymer (polypropylene, duplex, triplex) soft packages (pillow, stand-up bag).
The equipment consists of a pneumatic-mechanical packaging machine and a volumetric cup dispenser.
The filling and packaging machine AF-50-OM is the most productive equipment for filling and packaging (among its peers), capable of effectively pulling various packaging films with a width of 130 to 500 mm.

* Productivity depends on the volume and properties of the product being dosed, the length of the packaging and the 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 hopper neck into a “cup” fixed to the drum and located under the neck. The drum has such an arrangement of “cups” that when one “cup” is under the neck, the opposite “cup” is above the tube of the sleeve-forming device. That is, the “cup” located under the hopper neck is filled with product and the “cup” located above the tube is emptied at the same time.
When receiving an impulse from the control unit microcontroller, the dispenser electric drive rotates the drum, shifting the filled “cup” from the hopper neck towards the tube and placing the next empty “cup” under the neck. Upon reaching the tube, the filled “cup” empties, pouring its contents into the tube, on which the packaging film with a sealed back seam and bottom (package blank) is rolled into a tube (sleeve). Spilling through the tube, the product fills the package.
After dispensing a dose of the product, the microcontroller activates the film feed mechanism. When pulling, the roll unwinds and the film is rolled up, through the collar, into the sleeve around the tube. Having pulled the film to the required distance (determined by the photo mark or the value of the parameter “СЧt. 1”), the microcontroller activates the soldering unit.
The soldering unit of the filling 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 “euro-roll” 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-off package falls on the floor, into a special container (box) or onto a discharge conveyor.
After the welded elements are disconnected, the microcontroller again sends a pulse to the dispenser electric drive to rotate the drum and pour the contents of the “cup” into a new package. Additionally, the microcontroller of the packaging machine monitors the moment the roll of packaging material ends and other emergency situations.
Peculiarities.
The filling and packaging machine is optimal for packaging products that have good flowability and are capable of uniformly and quickly filling free cavities, such as cereals, rice, seeds, grain, seeds, salt, sugar, tea, coffee beans. The model is not applicable for packaging dusty or hard-to-flow products (flour, raisins, corn sticks). It is also necessary to take into account that due to the use of a volumetric dispenser, this packaging equipment is not universal and has restrictions on the change of the packaged product.
The difference between this machine and similar AF-35-OM and AF-45-OM is the use of a pneumatic-mechanical packaging machine, which uses combined drives (the film is pulled by an electric motor and belts, and the compression and unclenching of the welded elements of the soldering unit is done with the help of pneumatic drives). This combination significantly increases the speed of the filling machine and allows the use of wider packaging films than on the AF-45-OM. At the same time, the presence of pneumatic drives requires the use of a compressor, and as a result increases the noise level of the filling machine, but the noise level does not reach that produced by the AF-35-OM.
The packaging machine requires floor placement and has limitations on the width of the film used and the height of the formed package, specified in the technical specifications.
A modification of the filling machine is the use of a volumetric dispenser with “cups” with hinged bottoms, which allows more accurate and efficient dosing of small fraction products. In addition, the use of “cups” with hinged bottoms increases the productivity of the dispenser, respectively increasing the productivity of packing and packaging.
