Make the container more

The container is a modern transportation tool, and the full application time is not long. The utilization rate is not high. A 20-foot container has a volume of 33m3, a general loading capacity of 25m3, and a utilization rate of about 75%. A 40-foot container has a volume of 67m3 and a general capacity of 55m3. The utilization rate is about 82%. If the package itself is not full, the actual utilization of the container will be lower. This is the current status of transportation.

1 Ways to increase container loading

Based on the analysis of the current status of low container utilization, we conduct technical research from the following aspects.

1.1 Creating a New Idea for the Design of Containers for Containers

When a container of some kind is selected as a vehicle, the carrying space has already been determined. When the packing method of a certain kind of goods is determined, the volume of the container of this box of goods should also be roughly determined. How can we obtain the maximum container load? We think we must meet two conditions:

　 First, the box must contain as much cargo as possible.

Second, containers should be packed with as many containers as possible. In order to achieve these two goals, we have designed and manufactured our own patented measurement tool - three-dimensional caliper. Three-dimensional calipers can create a relatively closed condition for measuring goods. The goods are all contained and squeezed to a certain extent, so that the true volume of the cargo can be measured. To change the stacking mode of the goods, you can measure several real volumes of different shapes and add the relevant package thickness to get different packing box volumes. Carry out box calculations for these boxes and you can get different packing. As a result, it is not difficult to choose a box that is suitable for loading containers. At the same time, you can also make body adjustments and improve the box shape as needed.

The best box shape can generally be determined. The vast majority of cargo boxes can take many forms, and you can always find one of the most suitable box shapes for containers. At the same time, you can also make body adjustments and improve the box shape as needed.
The best box shape can generally be determined. Most boxes of goods can have a variety of styles, and you can always find one of the boxes that is best suited for loading containers. We can follow this principle to think and seek, and it is not difficult to achieve the goal:

1) The packing rate of the goods is not changeable, the quantity of packing is different, and the external dimensions must be different;

2) The arrangement of the goods is not changeable, the arrangement is different, and the dimensions must be different;

3) Whether the opening direction of the packing box can be changed, the opening direction is different, and the external dimensions must be different (the opening size of the packing box is larger than the size of other directions).

1.2 Establish an expression that communicates the intent of packing

From the design of the packing box to the packing and shipping, at least three units are involved, namely the manufacturer, the operating company, and the container station, which lasted for ten days. Therefore, packing intentions should have an expressive method that everyone can understand. Simple and simple stacking can be expressed through language and text, or through layered floor plans. However, it is necessary to express relatively complicated packing methods, especially packing methods of several packing boxes. These methods are difficult to express. clear. We use long-term understanding of the loading and unloading process of the container and use the schematic diagram to express it. It can intuitively reflect the stereoscopic orientation and legend of each arrangement and facilitate the packing operation. Dimensions are comprehensive, which makes it easy to check the clearance reserved in all directions of the container. The production of three-dimensional schematic diagrams is also very simple. The orientation drawings of drawings and containers are printed in advance. When you use them, you only need to draw a few parallel lines on the drawings, fill in numbers, and clip them.

1.3 Setting up a standard box and database to facilitate the design of containers

In order to more easily find out the dimensions of the container suitable for the container, according to the different specifications of the various containers, to prepare different standard container specifications, and to compile the various types of containers with high utilization rate and relatively successful loading. Database for reference when measuring and determining the dimensions of the cabinet. Try to use a standard box or a box with a high utilization rate to increase the design speed. As long as we continue to accumulate data and experience, the design of the packaging box will be faster and faster, and the better, the better.

2 Making full use of the new situation and prospects of containers

After adopting the new technology of “enhancing container loading”, it has now reached: a 20-foot container can hold 30 to 3 m3, not less than 2 m3; a 40-foot container can hold 60 to 64 m3, not less than 58 m3, using The rate can reach 90% to 96%. Each container can be loaded with 3 to 9m3 more. Due to the increased utilization of packaging boxes and containers, the loading of certain commodities has been greatly improved. For example, the company’s main export commodities are full-blown children's wear and full-thickness trousers. The load of 20 Infracore containers has increased from 2,500 to 3,500 dozen, and the load has increased by 40%.

Now, the freight rate is 50-230 US dollars per cubic meter for each freight, and 40-150 US dollars for the box price. Each container can save freight by more than 100 US dollars. In 1997, our company saved about 45,000 U.S. dollars in ocean freight. This technology has not yet been fully promoted. If it is fully promoted, it can save more freight.

After applying this scientific and technological achievement, it not only brought about considerable economic benefits for the company, but also brought changes to the company's employees' mental outlook. Now the clerk really pays attention to packaging and transportation work. As long as a box of goods is produced, they will design the packaging box together with the manufacturer, make full use of the container's capacity, and consider the maximum capacity of the entire cabinet when ordering. The number or quantity interval is traded.

Manufacturers have also made gratifying changes. They have changed the original design method. After designing the packing box, they must understand the calculation theory, understand the container data, discuss plans with the salesman, measure and calculate many times with measuring tools. Repeated comparisons only finalize the box. After packing, the actual size should be returned to the business unit.

Since the manufacturer and the operating company have already made preliminary preparations for packing, the container station can only operate in accordance with the packing diagram. In this way, you can speed up the packing speed and improve service quality.

There are many goods transported by container shipping and packaging, and the freight rate of containers is high. If we can attach importance to the packing and transportation of each batch of goods, we can certainly save a considerable amount of freight. If the technology is promoted nationwide and all enterprises in the country are implemented, no matter which factory produces and processes the products, and no matter where they pack, they have achieved the goal of making full use of containers. Therefore, the annual freight saved in the country will reach hundreds of millions of US dollars. .
