It is hard to imagine a modern system of distribution without the loads of palettes and palletized. With the exception of loads only of package, almost all dispatched in any quantity is placed on a palette and unitized in a load of high compact density for the transportation. The palettes are piled up, placed on the shelves (radiates) and controlled in a lot in a manner different with the objective to deliver products quickly and efficiently. The palettes did the handling of mass of extremely simple product and the truck of elevator of fork that moves itself palettes is common in the stores, the warehouses and any sector where the product is moved.

PORTABLE PLATEFORMES
Describe a palette and the product that it contains are frank. A palette is a raised plateforme on that the items are placed for the transportation. Typically, the items of palletized ae" the cases, the bags, the cans, clog, etc. ae" Are smaller than the palette. The palette becomes a transportation easily effective controlled mechanism as for the space for all the smallest items. It could be done wood, the plastic, the metal or the counsel of rippled kraft and is of rectangular ordinary one in the form with the standard size of 40 in. x 48 in. The product is arranged on the palette in a methodical and compact model allows effective handling through the system of distribution. The models are in accordance with the form of palette and produce the optimized load in the palette dimensions while maintaining the load of forthe of structural force.

The model conception is dictated by how the palette is checked in the distribution system. The palettes with a model conceived for an expedition receptacle can be different of those that move themselves by a system to transport in truck and a tormented warehouse in a distribution center. The cases are not piled up the same on every layer on most of the palettes. Rather, a set one in motion arrangement of case is used to stabilize the load. The cases are arranged by the length and the width against each other to form a layer of the put to bed multiple in the load of unity. Unless the cases are heavy or big, the rows or the put to bed are changed, normally is turned 180 degrees, maintain the structural force in the battery of the load and keep the put to bed to break to party in the crossing. A lot of models of palette produce deliberately small gaps or the openings in the put to bed. This gap is a how result the position of the cases ends up to create a uniform outside the cube on the palette.
In to determine how to the product of palletize, the packing engineer must have a general general idea of the system of distribution, the method of transportation and the conditions of storage of the product to determine the conception of load of palette. At first palletization of hand was used to pile up the product in the specified model. While this is the manner the more varied to pile up the product on a palette, this method is only effective when the rate of product is palletized is slow. Only product Palletization automated with a model of only palette evolved palletization of hand. Of high level palletizers was developed to check the operations of production of quick speed that produced the product to 50 to 60 (or more) the cases by the minute. The machines placed quickly of the and the piled up cases on a palette for the load. More of high level palletizers can check six put to bed or the product rows by the minute. This modest beginning of a type of machine of the mi-vingtia¨me century evolved now and increased in a method selection to place and to arrange the products on a palette.

PUT PRODUCE A THE PALETTE
There are four conceptions or the basic types of palletizers widely used in the industry today. These are high level palletizers, palletizers of low level, the articulated robots of arm and palletizers of portique. (Palletizers of type of portique can use an arm of robot or crane arrangement to choose and to place the product on the palette).
Beyond the four basic unities there is a number of typical others of palletizer with the very specialized conceptions. These conceptions address products or unique positions including mass palletizers for emptinesses the cans or the bottles, and various palletizers conceived to the packed products of palletize in the bags, the drums and the fa»ts. These are a small party of the general market.

Of the four conceptions or of basic types of palletizers it of high level or low is used most often for the operations of quick speed. This sometimes is referred to as the automation sets up (the machine does not move itself). The difference between the two conceptions how is arranged them first are organized and then are piled up on the palette.
The name "of high level palletizer" describes, usually, the operation of the machine. A palletizer of high level receives the product is palletized to an elevation or level strongly above the palette. The palette is nourished in the palletizer of a station of magazine or accumulation. As the palette between the palletizer it is raised and is disposed under a bed or a plateau. The product moves itself on the bed or the plateau and is organized in a layer or an only row of produce one. The palette is at the under level of the assembled row and the entire layer of produce one gently is placed on the palette. The equipment begins organizing then the second row of product, modifying the arrangement of the cases to equal the condition of the model of palette. An error leaf, a leaf of paper or a heavy scored paper, sometimes is used to separate the put to bed. The palette and the first layer of product are lowered to the height of a layer and the second layer is placed on the first. This decrease of the palette, the layer by the layer, is repeated until the correct number of layers is at his place. The full palette lowers then slowly to terrace the level and the movements by the escort one or the cart edledvateur to pitchfork to any banding or the lengthening that packs the salaried operation before the load. A second palette is transferred to the position, raised at the just level to the under forming bed and the process is repeated.

"The placement of the first layer on the palette and the placement of subsequent layers is critical in all the operations of palletizing," says Ted Yeigh, the Machine of Columbia Inc., Vancouver, Wash. The products cannot adjust the standard dimensions of a palette and when placed on the palette they "can overhang," or "underhang" the palette edge. (The surplomb means the case stick out beyond the edge of the palette, while underhang means that the product does not attain by the palette). The palletizer must place every layer of product on the palette in precisely the just position to minimize problems created when there is too the surplomb or underhang.

Palletizers of low level has the smaller advantage of tracks than the of high levels machine. A palette in a machine of low level or student is or lowered and the row or the layer is formed to a level more near to the floor. Every layer is formed on a bed and then raised and lowered to transfer the load to the palette to the stop. The bed returns then to the beginning position and the next layer is formed. After the palette is completely loaded, it is offloaded the palletizer and another palette is disposed and the process is repeated. Low Palletizers normally the movement two and probably three put to bed by the minute on a palette.

Automated Palletizers, the two have articulated the type of arm and portique, began appearing in the growing numbers in the last decade. The choice of ordinary considered and place systems, automated palletizers can take an only case or a multiple case of produce one of an or more of locations and the place to predprogramme of the places on the palette bed. The basic capacity of data processing, combined with the detectors to identify the product variations, the robots of brand systems intelligent that can identify and can separate the multiple product or the productions of packet. The robots offer also to the capacity to automate multiple chains of production with a machine. While placing offloads it multi-line close to a location of robot, a robot has the capacity to identify and to check multiple products. Automated Palletizers can produce also the multiple loads of palette base on the size, the form or the others to identify characteristic of the production of line of packing, on the multiple finished palettes. This is accomplished by the capacity of the robot to turn or dedplacerae”une capacity not available in the position sets up high- or low conventional palletizers. Palletizers of robot is the systems generally slower more than more conventional because they can check a case at once or because they manage multiple functions at the same time. They typically check 15 to 30 cases by the minute.
As all the robots, these used one in palletizing are described by the arm type that they use. The products or the smaller applications and lighter use an articulated arm with the capacity of multiple axis. The heavy products of weight count on a heavier arm or an arm of portique that typically has a limited number of chop movement. This distinction is not absolute nevertheless and the one can find angry examples with a lot of variants in the operations of palletizer of different robot.

The last group of machines is specialized palletizers conceived for the unique products or the occasions of handling of equipment. Mass Palletizers is the most common one of these specialized unities. A typical application of packing for a mass palletizer would construct loads of cans empty for the load of the canmaker to the stand-in. The empty packet is palletized to the using industrial location at least packing and then transferred to the stand-in. Can adjust well in this process of handling of mass, considering their high force of inherent column. The metallic cans are assembled in the put to bed on a palette with an error leaf between the put to bed. Every row of palletized of cans is banded to obtain the load and then transported to the can stand-in where the process is reversed and the mass cans are depallitized on an accessories line.

CHOOSE A PALLETIZER

The equipment of Palletizing underwent major changes in the past decade to maintain itself with the ask different on the part different of the chain of provision. "The new Interface of Human Machine (HMI) the checks transform conventional and automated palletizers," says Yeigh. "These checks allow the machines quickly to be put back in state to check the different sizes of case, the palette models of the and the put to bed product on the same machine".

The computerized checks furnish also improved data that muster and retrieve. The true report of time of production, the reports of alarm and the reports of dead time is certain of the customers of common capacities need to refine their operations, with the other pieces of important information to the provision chain, as the production schedule. A lot of the new machines contain also complete outlines and the operation manuals them that do simpler and easier for the people to fix and to repair equipment without a call to the equipment supplier.

In a lot of cases, the computer interfaces walk the operator or the mechanic by the repairs or preventive discussion. These interfaces allow the manufacturers of palletizer to produce quick machines that can check the smallest sizes of case.
"A lot of the big stores of can transfer to the smallest cases and in some examples of the traditional cases packages of product to shrink packed that increase the ask capacity and handling demanded on the machines," says Yeigh. The manufacturers and the retailers attempt to reduce waste and the packing, deliver the biggest quantity of product to the consumer with the less quantity of packing.

HMIs done also extremely varied palletizers. "An automated cell can check four or five industrial lines because they can be adapted to the variations of multiple product, and because they check typically only an or two unities by the movement," says Harry Horni of Priority the One, the Air of Beautiful, Md. "This gives them flexibility maximum in the construction model different palettes at the same time".

Automated Palletizers, notably palletizers of type of portique, transfer to a lot of centers of distribution. These robots can check of the to several lines and REFERENCES. ". . . (A portique) can check to several lines, sometimes 15 or more, and can produce the disposed in put to bed 'the palette d'arc-en-ciel' that does the more effective distribution. A palette d'arc-en-ciel is a where the put to bed different can contain different products," said Horni. "These systems can automate completely case to choose the operations for the products as the non Labrador drinks, where the different perfumes in the different quantities are necessary to the different stores".

The ergonomics is a big palletizers of affable advantage to the smallest manufacturers. "A palletizer, a low conventional level or robot, will minimize ergonomic problems associated with the monotonous movement, raising and the rotation by the employees that do hand palletizing," says Dave Mathews, the sales direct and the new development of the director of new products, Business of Engineering of Brenton, Alexandria, Minn. The small manufacturers become aware of these advantages and in a lot of cases install machines in the operations that were not considered for a palletizer base on the ergonomic improvements for only the employees.

Palletizers always has a lot the piece for the improvement. The capacity to organize at the level of case or unity began but always demands more refinement. The chain of provision of today, with his speed and his complexity, is a very new animal. The palletizers of surface of challenge takes an old idea and keeping it new and useful to the new manners of product of handling and distribution.
