The concept and role of sorting equipment

Sorting equipment is to complete out, distribution centers, picking, sorting, sorting operations of modern equipment, is to carry out sorting, distribution operations of a strong technical guarantee. At present, large-capacity warehouses and distribution centers at home and abroad, almost all equipped with automatic sorting machines. Checkweigher has a high sorting capacity and can handle a wide variety of goods. Such as Japan's distribution center in Fukuoka, Japan, the use of light control automatic sorting machine processing capacity, including light control systems and other systems of the processing capacity, the general daily processing capacity of 17,000, in addition to the winter and summer peak season daily processing capacity of up to 75,000. The number of originating and arriving goods is about 150 units per day. The automatic sorting machine adopts linear sorting machine, the way for tilted tray, sorting capacity of 8160 think/hour, sorting cargo weight of the largest 50kg, the smallest 0.1kg.

In recent years, with the rapid development of sorting technology, automatic sorting machine scale is getting bigger and bigger, sorting capacity is getting higher and higher, the scope of application is getting wider and wider, sorting equipment has become an important equipment in the warehousing equipment. Practice what, sorting equipment with high labor productivity, high degree of automation, technology-intensive, sorting capacity and other advantages, it is a modern warehouse indispensable advanced equipment, determines the operational capacity of the warehouse and the scale of operations, reflecting the high and low level of logistics technology.

Composition of automatic sorting machine

Automatic sorting scale is generally composed of control device, classification device, conveying device and sorting channel mouth. The role of the control device is to identify, receive and process the sorting signal, according to the requirements of the sorting signal to instruct the classification device, according to the variety of goods, according to the location of the goods delivered or according to the category of the owner of the goods for automatic classification. These sorting requirements can be through different ways, such as bar code scanning, color code scanning, keyboard input, weight detection, voice recognition, height detection and shape recognition, etc., input to the sorting control system, according to the sorting signals to determine a certain kind of goods should enter which sorting channel.

The role of the classification device is based on the control device issued by the sorting instructions, when the same sorting signals of goods passing through the device, the device action to change the direction of operation in the conveyor into other conveyors or into the sorting aisle. There are many kinds of sorting devices, generally there are several kinds of push-out type, floating type, inclined type and branch type, different devices for sorting goods packaging materials, packaging weight, the smoothness of the bottom surface of the packages and so on do not have exactly the same requirements.

The main component of the conveying device is a conveyor belt or conveyor, its main role is to make the goods to be sorted through the control device, classification device, and conveying device on both sides, generally connected to a number of sorting roadway, so that the classification of goods slipped off the main conveyor (or the main conveyor belt) in order to carry out subsequent operations.

Sorting roadway is has been sorted from the main conveyor (or the main conveyor belt) into the collection of goods into the area of the channel, generally by the steel belt, belts, rollers and other components of the chute, so that the goods from the main conveyor slides to the collection of goods platform, where the staff will be the roadway of all the commodities are concentrated or warehousing and storage, or grouping and loading trucks and distribution operations.

The above four parts of the device through the computer network linked together, with manual control and the corresponding manual processing links constitute a complete automatic sorting machine.

Applicable conditions of weighing and sorting machine

After the Second World War, the weight sorting machine gradually began to put into use in the developed countries in the West, and became one of the advanced and logistics centers in developed countries, distribution centers or circulation centers necessary facilities, but because of the requirements of the user must have certain technical and economic conditions, therefore, in developed countries, logistics centers, distribution centers or circulation centers do not use the automatic sorting machine of the situation is also very common. The following conditions must be considered when introducing and constructing automatic sorting machines:

1, a huge one-time investment

Weighing sorting machine itself needs to build a short of 40 ~ 50 meters, the length of 150 ~ 200 meters of mechanical transmission lines, and supporting mechatronics control system, computer networks and communication systems, etc., this system not only covers an area of large, easily more than 20,000 square meters, and the general automatic sorting machine is built in the main body of the automatic warehouse, so we have to build 3 ~ 4-story high three-dimensional warehouse, warehouse needs to be equipped with a variety of automated handling facilities. A variety of automated handling facilities, which is no less than the establishment of a modern factory requires hardware investment. This huge upfront investment will take 10 to 20 years to recover, if there is no reliable source of goods as a guarantee, it is possible that most of the system is invested by large-scale production enterprises or large-scale professional logistics companies, small businesses can not afford to make this investment.

2, high requirements for commodity packaging

Metering sorting machine is only suitable for sorting the bottom of the flat and rigid packaging rules of goods. Bagged goods, soft and uneven bottom of the package, packaging easily deformed, easy to break, ultra-long, ultra-thin, overweight, ultra-high, can not be tilted goods can not use ordinary automatic sorting machine for sorting, so in order to make most of the commodities can be automatically sorted by machinery, you can take two measures: First, the implementation of standardized packaging, so that most of the commodities of the packaging in line with the national standards; the second is to be based on the sorting of the The second is to customize specific sorting machines according to the uniform packaging characteristics of most commodities. However, it is difficult to make all the suppliers of goods to implement the national packaging standards, customized special features of the sorting machine will make the cost of hardware, and the more special its generality will be less. Therefore, the company has to determine whether or not to build or what kind of automatic sorter to build based on the packaging of the commodities it operates.
