With the development of e-commerce and logistics industry, express delivery has become an indispensable role in life. The domestic express delivery business has maintained a high growth rate of around 50% for five consecutive years. In 2017, the total business volume has reached 40.06 billion pieces, that is, an average of more than 100 million express deliveries per day. However, as the demographic dividend subsides, the cost of employing people continues to rise, the traditional logistics system seeks reform, and the advantages of smart warehousing are highlighted.

In August 2016, the first fully automated warehouse of the rookie alliance officially opened its position in Zengcheng, Guangzhou, achieving a new breakthrough in China's warehousing intelligence. After the consumer places an order on the e-commerce platform, the order information is instantly obtained in the warehouse and a barcode is formed. The bar code is affixed to the courier box and the box begins to enter the automated track.

Next, the courier box is under the guidance of automation, to pick the goods. In this way, labor only needs to be invested in bar code review, sorter monitoring, etc. The seven links of transportation, warehousing, loading and unloading, and transportation of goods can be integrated and integrated, the efficiency is increased by at least 30%, and the picking accuracy is almost reachable. 100%.

Closely related to consumers, as more cities deploy intelligent logistics warehousing bases, online shopping day and second-day services have covered thousands of districts and counties across the country.

Jingdong Logistics is also one of the best. Through the layout of the nationwide self-built warehouse distribution logistics network, it realizes high-quality logistics services such as limited time and speed.

Warehousing intelligent and unmanned will be the trend. For logistics enterprises and retail circulation enterprises, how to build a company-specific intelligent warehousing system? Zhou Weilong, a senior domestic automated warehousing logistics planning expert, shared on the platform of Hansen Business School. "How to build a smart warehousing system in the new retail era":


The macro environment of the new logistics era

The emergence of a new era is inseparable from the promotion of the macro environment. What are the macro environmental factors driving the development of the new logistics era?

The rapid development of China's e-commerce in the past 10 years has accelerated the rise of smart warehousing. According to the annual growth rate of e-commerce warehousing close to 30%, the high growth rate poses new challenges for the storage hardware and software; the improvement of customer service quality requirements has prompted the upgrading of storage hardware and software......

Driven by the national supply-side reform, Industry 4.0 and China Manufacturing 2025, the concept of “Internet +” warehousing 4.0 has spawned, providing a high degree of integration between the network and intelligent warehousing hardware, and pointing out the direction for smart warehousing development.

The national “One Belt, One Road” strategy promotes enterprises to carry out in-depth strategic thinking. At present, domestic logistics enterprises not only need to think about the status quo, but also need to combine the national strategic opportunities of the Belt and Road, so that warehousing enterprises can start to think about the development strategy of the enterprise and root the domestic market. A new strategy to advance overseas, this is a very important strategy, if it is outdated, it may soon be surpassed.


The characteristics of intelligent warehousing in the new logistics era

4 new features in the field of intelligent warehousing:

1. Wide application of automation and intelligence

Mainly refers to hardware parts such as automated warehouse system, automatic sorting equipment, sorting robots and wearable devices such as VR augmented reality technology; subdivided into automatic warehouse, including stereo storage system, shuttle, etc., sorting Robots are mainly used in joint robots, robots, and spiders.

2. Internet + smart storage equipment

This part focuses on software, mainly Internet applications such as big data, cloud computing, AI, deep learning, Internet of Things, machine vision and other wide-ranging applications. The use of these data and technology for the sale and forecast of goods, as well as the allocation of smart inventory and the exploration of personal consumption habits, can achieve accurate sales according to personal consumption habits, currently more mature companies such as Jingdong, rookie, etc. have been used Big data is pre-sorted.

3. Sharing

The emergence of the sharing economy is reflected in the warehousing field, such as the sharing of warehousing and logistics equipment such as pallets, containers and forklifts. For example, the rookie outsources the operations and hardware equipment in some warehouses, and is only responsible for the construction of land and warehouses, as well as the sharing of warehouses, such as the collaborative warehouse of Jingdong and Danone Beverage, and Jingcang.

4. Overseasization

With the national One Belt and One Road strategy, domestic consumption upgrades, cross-border import and export areas ushered in new opportunities for development, companies to accelerate the global distribution of overseas ... ... cross-border overseas warehouse demand surged.


Smart storage equipment

The creation of intelligent warehousing system is inseparable from the organic integration of efficient and advanced software and hardware. Here are some of the hardware facilities and equipment for smart storage. You can combine them according to your actual needs. The following is a brief list:

Automated transportation system

It mainly includes belt conveyor line, roller conveyor line and pallet conveyor line. It is mainly used for the transportation of cartons and totes. The related manufacturers mainly include Rui Shige, Dematic, Dema and so on. This system can be done by many manufacturers, and its technical content is relatively lower than others.

2. Automatic storage system

It includes two parts: an automated warehouse and an automated dense storage system. The essential equipment for automated warehouses is:

Stacker: pallet stacker (applied in pallet stereo warehouse), bin stacker (Miniload- mainly used for three-dimensional warehouse of box materials); major domestic manufacturers include north, Kunming, corundum, etc.; The main manufacturers are Rui Shige, Dematic, etc.; domestic and foreign countries are currently not technically speaking, there is not much technical difference, the main difference is the accuracy. There are pallet conveyor systems in the three-dimensional warehouse, such as multi-layer shuttles (shuttles, sub-cars, etc.), companies in this field such as TGW, Rui Shige, Dematic, Lanjian, MasterCard.

Automated intensive storage system, mainly used for storage of boxes, related manufacturers have TGW, Rui Shige, Sheng Feier, the domestic is not doing well in this field.

3. Automatic sorting system

Automatic sorting systems are currently hot, especially in the express delivery industry and e-commerce warehouses.

Cross-belt sorting system and turn-up sorting system: mainly used for sorting and single-piece picking of boxes. The better manufacturers are Berman, Dematic, Post, and three.

Slider sorting system: mainly for sorting boxes, and doing better companies such as Vanderland, Dematic and so on. Installed between the belt conveyor line and the drum line, there are two devices that can be separated on the left and right sides (referred to as: balance sorting system); balance sorting system: mainly for sorting boxes, such manufacturers are like Vanderland, Germany Mattek, Rui Shige, domestic Kejie.

4. Robot sorting system

The robot sorting system mainly implements the sorting system for goods and people on the shelves and parts. It is usually AGV (automatic guided vehicle). Everyone knows: foreign Amazon kiva sorting system, domestic extreme wisdom, fast Warehouses, road innovation and other companies.

There is a small yellow person matrix sorting system in the sorting system of AGV. The AGV is placed on the matrix for sorting, mainly for the sorting of parts, such as Hangzhou Liyi, Haikang, etc. And Shentong's sorting bins are all used by the Xiaohuangren matrix sorting system.

5. Goods picking system

There are many kinds of pick-up systems for pick-ups. There are two main types here:

Automated horizontal rotation library: mainly for box storage, on behalf of the company has Cadiz, Shengfeier, etc.; the disadvantage of this system is that when the transfer, the entire inventory is turning, the energy consumption is high when using; if the inventory is small Not cost effective, and the cost is relatively expensive;

Automated vertical rotary library: mainly sorting small items such as screw electronic components and medicines. You may have seen this kind of sorting used in medicines in hospitals. On behalf of the company, there are electric institutes, Hennell, Cadiz and so on.


How to build your own intelligent warehousing system

How should enterprises build their own intelligent warehousing system? It mainly focuses on the planning principles of intelligent warehousing, the planning of site process plans, the determination of intelligent equipment options and technical parameters, and the quality control of project implementation.

1. Planning principles for smart warehousing

No matter how advanced intelligent hardware and software are used, they must be rooted in the actual situation of the enterprise.

It is necessary to have a clear strategic positioning, reasonable business growth rate prediction and positioning, and suitable and advanced information architecture planning.

Equipment technology is mature and advanced, not outdated; choose the appropriate efficiency, not the highest

The scheme is as flexible as possible and scalable

The scale of production capacity does not involve too much or the estimate is too tight

Minimize customization and make it as replaceable as possible

Minimize manpower input, reduce people's labor intensity, minimize the difficulty of people's operational skills, and minimize the error rate

Make it simple and easy to make

To the space, as little as possible to the plane

Inflow and outflow must be balanced in the process plan, avoid bottlenecks

2. Planning of the site process plan

The rationality of the process plan depends on the collection of basic data. The data collection should be as accurate and reliable as possible. The basic data includes the size, weight, outer packaging of the goods, the proportion of the whole pallet / full container and zero, the number of SKUs, SKU Characteristics, daily inbound and outbound volume, order line count, order quantity, warehouse turnaround time, inventory quantity, etc.

Data collection and EIQ analysis, EIQ analysis is a prerequisite for process planning.

The planning and rational design of the process, smart warehousing and traditional warehousing are similar in the process, there are many differences, which requires decision makers to break the traditional concept, can not blindly follow the inherent thinking to design the program. Some processes can be simplified and deleted, and must be emancipated. The so-called rationality is to meet the actual needs.

The planning of the location and size of the functional area, such as the three-dimensional warehouse storage area, the sorting area, the replenishment area, the review area, the collection area, the routing sorting area, the delivery area, etc., all need to be reasonably planned according to the business requirements.

The planning and design of the cargo space is also very important. For example, the explosive products must be relatively close to the packaging, review, and outbound areas. In addition, if the returned goods, heavy goods, and light goods are placed in which position, they need to be done. Good design.

Reasonable planning and design of moving lines. The moving line is the core of the core in the warehousing plan, and all business operations are connected by moving lines.

Post design and manpower planning. This is a branch of IE (industrial engineering) called job design and manpower planning. For example, according to the current business volume and processing capacity, how many people need to be arranged in this position, such as replenishment, packaging, warehousing, picking, etc. Wait.

3. Selection of intelligent storage equipment and determination of functional parameters

Automated conveyor system: The dynamic line parameters are determined according to the processing capacity and the upper limit parameters. The general box type sorting system width is 580/620/680/720/780, and the width is the physical size of the goods transported on the moving line. In the decision, the weight is related; for example, the bearing capacity of the wire body, the power selection of the motor, etc., generally selected is about 2,500 boxes / hour, and the commonly used speed is 32 meters / minute.

Automated warehouse: The speed of the pallet stacker is generally below 180 m/min, while the miliload can be up to 240 m/min. The maximum number of accesses is up to 250/h, usually 200/h. The height can be up to 30 meters, generally less than 24 meters, basically 24 meters, 21 meters; multi-layer shuttle, access capacity up to 1000 times / hour.

AGV sorting robot: mainly AGV sorting matrix, which is widely used in the unmanned warehouse of Jingdong. The concept of unmanned warehouse is more advanced, but the large-scale application of this small yellow matrix sorting system is not cost-effective. The failure rate is high and the background scheduler algorithm is complex; and this matrix type AGV sorting system belongs to two-dimensional code navigation, and has a bottleneck: the more AGV cars, the more the processing volume will decrease.

Automatic sorting system: slider sorting machine for box sorting, which can not be sorted for goods with flexible packaging; cross belt sorting, mainly used for subdivision, can provide more grids (The destination is the sorting destination), the running speed is high, the sorting capacity can be 20,000-40,000 pieces or even higher; the single equipment will generally not exceed 30,000 pieces...

Electronic labeling system: mainly used for picking and picking fruit picking, solving the problem of sorting error rate, which has lower error rate and effectively improves sorting efficiency; the general electronic labeling system has an error rate of less than five ten thousandths. The use of electronic labeling systems is more efficient than manual sorting.

Dense storage system: We have mentioned two kinds of vertical and horizontal rotation libraries. The vertical rotation library can be used in a single machine, while the horizontal rotation library needs to be used together. The efficiency is 6-10 times higher than the manual. Since dense storage systems can increase storage density by about 50%, they can save up to 50%-60% of storage space. At present, dense storage systems are not used much in e-commerce warehouses.

Goods-to-person system: specifically refers to AGV goods to people, that is, everyone sees the kiva system, that is, moving around the shelves; there is also a goods-to-person system called online picking workstations, generally up to 1000 pieces / hour, traditional picking 70% of the time is spent on the road, 30% of the time is used for picking, and the efficiency is low; the efficiency of the goods will be greatly improved by using the goods-to-person system.

Online robot sorting system: The main problem is that the price is relatively high. For the storage industry, the price/performance ratio is not high, and the efficiency cannot be compared with the manual; but one advantage is that it can be hyped, and the image of the tall image of its own brand is The benefits, currently appearing in Jingdong and rookie, are rarely used in other e-commerce warehousing.

4. Control of project implementation quality

It is necessary to confirm that the quality of the equipment meets the design requirements and retain the evidence;

Draft an acceptance test specification for the project to provide a basis for acceptance.
