The mechanically driven filling and packaging machine is designed to organize a continuous cycle of weighing bulk products (cereals, nuts, coffee, crackers, chips, candies, cookies, granules, animal feed) and packing them in polymer films (polypropylene, duplex, triplex). During the packaging process, the machine forms a stand-up bag or pillow bag type package.

The equipment consists of a mechanical packaging machine and a weighing electronic batcher.

The filling machine is universal, the most compact and easy-to-maintain equipment (among similar models), does not require a compressor, and also has the ability to change the dose weight, dimensions and characteristics of packaging materials.

Characteristics.

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

Description of work.

The packaged product is poured through the hopper neck onto a vibrating tray, which, vibrating with a given amplitude, feeds it into the weighing bucket. The bucket is attached to the dispenser frame on a strain gauge (strain gauge). When the specified weight parameters are reached, the strain gauge sends a signal to the weigh batcher control unit (the Libra controller), which stops the vibrating tray, ceasing the product feed.

When receiving a pulse from the packaging machine control unit (the Unloading signal), the dispenser controller sends a signal to open the weighing bucket. The bucket opens, pouring its contents into the funnel. Through the funnel, through the tube of the sleeve-forming device, the product is poured into a folded tube (sleeve) of packaging film with a sealed back seam and bottom (packaging blank). At this time, the controller turns on the vibrating tray to fill the weighing bucket with the next portion of the product.

The operation of the packaging machine is controlled by a microcontroller located in the control unit, which, after unloading the weighing bucket (dispensing a dose of product), activates the belt mechanism for pulling the film. When pulling, the roll is unwound and the film is rolled up through the collar into a sleeve around the tube. Having pulled the film to the required distance (determined by a photo mark or a specified value), the microcontroller activates the sealing unit.

The sealing unit of this 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 a “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 package falls on the floor, into a special container (box) or onto the outfeed conveyor.

After opening the welded elements, the microcontroller of the packaging machine again sends an impulse to the “Libra” controller (the “Unloading” signal), filling the next package. Additionally, the microcontroller monitors the end of the roll of packaging material and other emergency situations.

Peculiarities.

The packaging machine is ideal for packaging products of any flowability, with the exception of dusty ones (flour, powdered sugar). Considering the dosing method and the characteristics of the weigh batcher, this packaging machine allows you to arbitrarily change the portions of the packaged product, as well as achieve the most accurate dosage. It has no restrictions on changing the packaged product, which are present in the machine with a volumetric batcher (AF-45-Ob).

The difference between this packaging equipment and the similar AF-35-V is the use of a mechanical packaging machine, which does not have pneumatic drives. This, accordingly, does not require the use of a compressor, which means the machine is quieter in operation. In addition, this packaging machine has smaller dimensions and higher productivity than the AF-35-V.

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

The packaging machine is available in models AF-45-V1, AF-45-V2, AF-45-V3, AF-45-V4. They differ in the number of weighing buckets (“streams”): in AF-45-V1 – 1 “stream”, with a capacity of up to 600 packages/hour, and in AF-45-V4, respectively, 4 “streams”, with a capacity of up to 2,400 packages/hour. A separate modification of this packaging equipment is the use of a two-level weigh batcher, which allows for more accurate and efficient dosing of hard-to-flow products that do not have constant flowability. For example, chips can either get stuck in the hopper neck (vibrating trays), or spill out in large, clumped portions. Accordingly, the dose size may have undesirable deviations from the specified one. To eliminate this, the batcher uses 2 levels of vibrating trays.
