Products from the manufacturer to the user must go through the handling, transportation and other links. During this process, due to the influence of transportation, loading and unloading tools and transportation environment, various mechanical loads may occur, such as impact and vibration, which may cause product damage. Therefore, products must be scientifically and rationally packaged before entering the circulation field. Even if damage still occurs, what is the reason?
After repeated studies and experiments, it was found that many of the damages were not due to poor packaging but due to improper fastening measures in the transportation process. This issue is particularly prominent in the export of electromechanical products. This article takes the export packaging of “Seeuritas†machine and equipment of Hamburg Export Packaging Co., Ltd. as an example to introduce how Germany solves the problem of fixed protection in product packaging and transportation.
Germany's fixed protection of mechanical and electrical product packages usually adopts the following methods:
Seat belts or safety chain fastening methods use seat belts (chains) to increase the pressure on the packages, which in turn increases the friction between them and the base or the use of the tool base plate, but also in the opposite direction of the package moves. A certain amount of pulling force is generated to prevent slippage and movement during transportation. Seat belts are made of mostly chemical synthetic fibers and are equipped with hooks and tension devices. Their maximum tension can be up to 2,000 Newtons.
The bottom fixing method fixes the package (such as equipment) directly on the sleepers and sliding wood of the base with anchor bolts. If the bottom of the package and the loading surface of the vehicle are all wood materials, a double-sided metal sheet can be placed between the two, and the tip of the teeth can be embedded in the upper and lower surfaces. Can also play a certain role in anti-slip.
Pressure bar fastening method uses a pressure bar to press the package firmly on the base. Its structure is usually two long screws equipped with nut washers, and they are fixed on the sliding timbers on the two sides of the package, and the pressure poles are put into the upper screw and tightened with nuts to press The effect of tight packing prevents it from moving. Of course, when using this method, a layer of cushion material must be placed between the pressure bar and the package to prevent damage to the package.
The block positioning and fastening method uses a wooden block package that conforms to the outline of the package, and the block is usually fastened or bolted to the sliding block or the sleeper. A layer of foam must be placed between the block and the package to prevent the package from being scratched or crushed. This method is also suitable for fixing the package inside the container or on the platform box.
The filling method places fillings between packages or between packages and boxes to eliminate gaps between them to prevent movement. Common fillings include airbags and other cushioning materials (corrugated cardboard, foamed plastic, etc.). The airbag here is a larger bag made of paper-plastic composite material. When in use, the airbag is first put into the gap and then inflated until it is fastened. In addition to this, there is a tray packaging fastening method using a stretched or contracted film wound, and a baffle or bar-type fixing method at the time of loading.
Securitas commonly used fastening methods in the export packaging of mechanical and electrical equipment are seat belt fastening method, bottom bolt fastening method, press bar fastening method and wood block positioning fastening method. Usually several methods are used simultaneously. For example, the bottom bolting method is mainly used, and then the seat belt and wood block positioning fastening method are used. Presser bar fastening is often used for plates, tubes, and comparative Founder equipment. Due to the characteristics of the equipment packaging itself, the pallet packaging and fixing method is hardly used in the company, and the filling method is rarely seen, especially the airbag filling is less common. This air bag filling and fixing method is currently rarely used throughout Germany, mainly because of its high cost and inconvenience in use.
Another protective measure often used by Securitas in the process of exporting and packaging electromechanical products is between the package and the base, or between the package and the platform container floor, or between the package and the vehicle. Or a foam pad, the slip effect of this method is also very obvious because it increases the coefficient of friction between the device and the base or between the package and the vehicle. In addition, Securitas must check the safety measures of the corresponding packaging design before packaging of electromechanical products, so as to know whether the fixed protection adopted is sufficient to prevent the slippage of the packaging during transportation, or else further improvement is needed. Here is a brief description of the principles of calculation and verification. Most of the company's packaging equipment is shipped by sea. According to the impact force of the transport ship in all directions during shipping, combined with the weight of the package, and according to the tightening measures to be taken when the package is provided, the external force, such as the safety belt With the tensioning force and the tightening force of fastening bolts, it is possible to calculate the slippage of the packaging during transportation. If it is possible to move, then add fasteners, and you can calculate how much you need to increase.
The export of electromechanical products can not only consider the transport packaging itself, but also must consider the fixed protection issues of the package during the entire transport process, and only in this way can reduce or avoid damage during the entire logistics process. In addition, in the export packaging design of electromechanical equipment, necessary checks can also reduce damage.
