Automatic lines

By automating the processes of filling and packing products, we get clear advantages over manual and semi-automatic packing options. The main of these benefits are:

1. Savings due to lower costs for wages, electricity, logistics, etc.
2. The packaging is uniform, has a stable shape and quality, regardless of the moral and physical condition of the worker who produces the packing.
3. It is possible that some options can be performed that cannot be performed manually, or are impractical, etc.

The question arises: "Why, in this case, people do not purchase exclusively automatic equipment?" The fact is that automatic packing lines are usually highly productive and if they are not properly loaded, the cost of packing increases dramatically. In other words, if the production volume for loading the machine is not enough, then you have to purchase a semi-automatic or manual machine.

The machines can perform both the entire range of packing operations, and some of the latter. An example of the first case is the packing of bulk products in plastic film bags. The machine forms a bag from the web, doses the product to be packaged, seals and cuts off the bag, puts down the dates of manufacture and expiration date, makes the necessary options, for example, punching Euroslot, holes for a stud. An example of the second case can be the packaging of dairy products in polymer containers. The machine does not manufacture containers. Ready cups are placed in special stores (cassettes), from where they are automatically removed, the product is dosed into them, a lid made of aluminum foil is placed on top, sealed, date is stamped, etc.

In automatic mode, individual functions can also be carried out, such as counting packages or dosing. Considering the frequency of their use, we will focuse on automatic weighers in more detail.

In modern enterprises, where there is a need for a clear dosing of the amount of liquid, bulk and other products, an automatic weigher is often one of the most important devices directly involved in the production process. When preparing building mortars, for example, it is necessary to dose crushed stone, sand, cement, water and various additives into a mixer. All this can be done automatically, without human intervention, by a signal from a time relay, either from a limit switch located on the valve emptying the mixer, or in some other way.

Dosing, depending on the need, can be carried out by weight, by volume, by time, by the number of revolutions of the dosing element, by count (quantity), etc.
