A palletizer is an equipment designed to create pallets, moreover, those that consist of several layers. The products, which were packed on the palletizer, have a neat and compact appearance, they are protected from various external influences and are ready for the conventional palletizer. Palletizer and pallet wrapper should not be confused. All products are delivered to the palletizer earlier, it forms an even rectangle, which already in this form is sent for further packaging. Usually, the equipment has two modes: performing simple stacking and forming a briquette from several layers of the conventional palletizer.
The main advantages of palletizers are considered to be their performance. These are incredibly productive machines, their equipment makes it possible to service several working lines at once.
The principle of operation of a palletizer is that products with a common group packaging are fed to a conveyor platform equipped with a palletizer. Here it is unpacked and stored. When the products have accumulated in sufficient quantities, a special system pushes them onto the table. Then the products are sent to a wooden pallet, where platinum is laid out between the layers of products. After that, the products laid in this way are moved further for packaging using forklifts or a mobile conveyor.
Palletizers are usually classified into several types:
1) palletizers with automatic software, capable of performing the functions assigned to them independently, without requiring the participation of the operator. Automatic palletizers, in turn, are subdivided according to the type of their location on the base. There are palletizers based on a Cartesian robot. This type of palletizer is called gantry, the module of which is capable of moving along horizontal and vertical center lines.
2) There are also palletizers located on the basis of a robot that manipulates the device using a mechanized gripper.
3) if partial automated stacking is assumed, a semi-automatic palletizer is used, in the course of which the operator takes part in the specified functions.
Usually, such items as wooden pallets are already used in the equipment of such equipment. This is a productive equipment, since its use eliminates all those mistakes that can be made during manual packaging. Currently, the widespread use of palletizers is due to the fact that the goods must be provided in a compact and reliable container, so they perform the main function in the formation of good packaging.
Palletizer performance is usually measured in cycles per minute. This parameter will depend on what model the palletizer has and what kind it looks like. The average is about fifteen cycles in one minute. The palletizer is currently going through a large number of upgrades. It can also be made in the form of gantry machines or in the form of a manipulator robot.
The palletizer, made in the form of a robot, is fully automated and works with software. Such a palletizer independently performs all processes, including delivery to the table and moving to pallets.
The formed box is transferred to an automatic pallet forming station (palletizer). Pallets are automatically fed to the station from the store for 5-6 pallets.
The first operation is to turn the box to the required position on the rotary roller table. Further, a separate row is formed from the correctly rotated boxes, which is then shifted onto a pallet using a hydraulic pusher.
When the next layer is set, the pallet moves down to the height of the box, so that the pusher moves the next row of boxes to the previous layer. Cardboard spacers between layers, if necessary, are laid manually by the service personnel.
Next, the finished pallet is transported to an automatic machine for palletizing pallets with stretch film. The pallet is installed on a rotating drive platform, the operator fixes the edge of the film on the pallet and turns on the machine from the operator's console.
The formed pallet is pulled by the film with a predetermined tension, overlapping height and the number of layers (revolutions) of the film. After the end of pallet formation, the completed pallet is automatically removed from the loading station area, making room for an empty pallet. The packed pallet is transported to the finished goods warehouse. The pick-up pallet delivery system is synchronized with the empty pallet feeding system
