What are the modes of the automatic sorting machine?

In the long run, e-commerce is the general trend. In the boom of e-commerce, logistics has increasingly become the key point. Jingdong’s big investment in the logistics system, Taobao’s big logistics strategy, and the large and small logistics centers of traditional enterprises entering the electricity supplier have attracted considerable attention. Quick sorting and delivery within a short time have become the focus of competitive advantage of e-commerce enterprises. The automatic sorting machine has become the favorite object of the major logistics companies. So, what are the modes of the automatic sorting machine? Here is a little editor for you to answer.
One, “RF picking +PTL sowing” mode
“RF picking +PTL (electronic label) sowing” means that after the logistics center receives the customer sales order, it starts picking operations according to the distribution station, distribution time, the order of the express company and so on, and divides the numerous orders into one order picking wave. Each wave number includes multiple orders to generate a picking list. If the interior of the warehouse is divided into multiple picking areas, in order to improve the picking efficiency, the picking list is further dismantled into a number of small picking lists, and each small picking list corresponds to a picking area. Use RF to pick up goods in different areas and merge the selected items into a turnover box. Then transfer the turnover box to the PTL (electronic label) sowing rack, and distribute the goods to one customer. Then check the goods of each customer, and finally package and collect goods to the corresponding distribution stations.
1. Process description
(1) start the wave. Generate picking list and picking list, send the picking order to RF to pick up goods.
(2) pick up the goods. The picking man uses the pick up truck to pick up the goods, and one picking truck is placed at the same time with multiple turnaround boxes, usually 6~8, which are used inside the logistics center. Use RF to pick up goods from each picking place and put them in the turnover box. After picking up a picking area, the selected items are placed on the pre picking shelf.
(3) confluent. A confluence turnaround box is used to collect the goods on the selected shelves in turn, and a confluent turnaround box collects the goods of a picking list, which corresponds to a number of customer orders. After the completion of the confluence, transfer the turnover box to the Re-bin Wall sowing area.
(4) PTL sowing. Scan the box code of the turnover box, scan the barcode, and put the goods into the customer’s slotting location according to the instructions of the electronic label lamp.
(5) print the documents. After the sprint is completed, print out the customer’s invoice, invoice and face sheet.
(6) packing. Put the invoice, invoice and goods in the package / bag, pack and place the sheets on the outer case / bag.
(7) collect goods. The collector sets the customer’s parcel to the collection location of the distribution site.
2. Scope of application
The logistics center with large annual distribution, large single warehouse, high investment in hardware and high accuracy in picking goods is suitable for RF+PTL picking mode. For large logistics centers, automatic sorting machines can be used to automatically distribute customer parcels to each distribution station or collect cages to improve the sorting efficiency.

Two, “label picking + label two sowing” mode
Label picking + label two time distribution “means that the logistics center starts picking wave times, each time includes multiple customer orders, printing the picking labels of the wave times, one piece of goods and one label (including customer order number, picking and cargo information, etc.). The picker picks up one lot of goods at a time, picking out the goods according to the labels and placing them in the pickup truck. Once a wave is finished, pick up the truck to the sowing area, put the goods into the customer’s slotting location, and use RF to associate the goods with the picking labels and the slots. After the sowing is finished, print out the invoice, invoice, face sheet and put it into the customer’s slots. Then, check the goods and documents, package, weigh and collect goods.
1. Process description
(1) receive the customer sales order. WMS receives customer sales orders of ERP system and generates distribution notice in WMS.
(2) start the wave. Distribution operation, also known as “wave management”, through the order source, express company, whether there are invoices, whether VIP customers and other ways to select the distribution notice form, distinguish the wave, start the warehouse internal operations, generate the warehouse pick picking use order. At the same time, the system automatically determines whether the goods need to be replenished from the storage position to the picking position according to the quantity of the demand for the goods and the number of the selected locations. If the replenishment is needed, the replenishment list is automatically generated and the replenishment instruction is sent to the RF of the tonic.
(3) replenishment. Replenishment personnel replenish goods that are not enough in order of picking stock; support multiple replenishment timing and replenishment strategy, including the amount of a wave demand before picking up the order of picking, and several kinds of operation methods, such as replenishing the goods to the picking position, and so on, and supporting the replenishment strategy according to the customer’s individualized demand. And the replenishment algorithm.
(4) pick up the goods. Each picking clerk can work multiple orders at the same time, such as 50 or 100 orders, depending on the quantity he can pick. The order behavior 1 goods are placed on the first floor of the picking trolley, and not 1 of the goods are placed on the two level of the picking trolley. In order to facilitate the workload of the assessment, pick up staff pick up labels, brush staff card, statistical workload.
(5) sowing. After picking up the goods, put the goods on the slots. An order corresponds to a sowing place. When goods are put into cargo spaces, RF is used to scan the goods picking labels and scan the location bar code, and associate them with RF.

CNC cutting tools, hard material technology!

In the mold manufacturing process, the use of hard material milling technology can replace some of the most expensive and most time-consuming processing steps, which can eliminate or greatly reduce the work of electrode milling, EDM processing, grinding, polishing, and point by point dressing on press.
Processing in “walnut shell”
Hard material milling technology is a branch of high speed machining technology. The core of high speed machining technology is to carry out multiple minor cutting processes with close steps, thus leaving only very tiny machining traces on the machined surface. The goal is to greatly reduce the requirement for subsequent processing. For the tool, in order to achieve effective chip load, the tool feed speed and spindle speed must be greatly improved to exceed the normal processing speed used in the traditional processing technology, so the process is named “high speed machining”. High speed feed also greatly improves the cutting speed of cutting tools, so the speed of machining workpiece is faster than that of traditional methods.
The technology of hard material milling is a step further than the concept of high speed machining. The combination of high speed light cutting and high speed spindle can effectively process hardened steel, so that the original properties of materials can be maintained. At the same time, a small diameter round end end milling cutter is used for high speed machining with close interval interval. The surface finish of the machine is close to the level of hand grinding and polishing. Because steel is processed under hardened condition, there is no need for subsequent heat treatment, stress relief or grinding. More importantly, this process can also replace many EDM processes with high processing cost.
Another advantage of hard material milling technology is that it can guarantee very precise tolerance size (10mm), which is precious to die processing. The moulds after processing do not need to be trimmed by manual work, and the shape of the die is completely consistent with the CAD design model because of the degree of no manual finishing after processing. Moreover, the processing of mould mating surface has reached the level without any dressing. The concept is to follow the parting line, usually at one end of the die cavity, to make a little bit more precise, so that it is slightly lower than the nominal size. In this way, when the half of the die is closed, a little gap between the contact surface of the die can be left, but the gap is very small (usually only 0.2mm), so that a part of the plastic can be flow out in the injection molding, but the die can still keep the closed state effectively. Moreover, when molten plastic is injected into the mold, this gap also allows air to be removed from the gaps without prior ventilation. The small contact pad on the corner keeps the gap, otherwise the contact between the closed surfaces will not be able to touch each other. Generally speaking, the interference between these mating surfaces must be solved in the process of point by point dressing and matching. There is no such problem now. When the core and die cavity are closed, the interaction between the surfaces is eliminated because of the clearance, so the surface is completely protected and the parts produced will not appear to be flying.
Improve efficiency from the tip of the knife
Mastering the technology of hard material milling may be a challenge. The way to understand hard milling technology is to know how to protect the tool tip. Concentrate on making cutting tools safe and effective. If all of these are managed in an orderly way, the tip of the end milling cutter can be integrated with the processed materials and be machined freely. If any part of the system is neglected or interrupted, the tool tip will suffer and the whole process will fail.
Taking the problem of end milling as an example, the following factors should be noted:
1. Cutting tools
Generally, round end end mills are used for rough machining, semi finishing and finishing. The round end milling cutter with two chip grooves is specially used for finishing. In the hard material milling process, these finishing tools are very important. A round end end milling cutter for finishing must meet two key requirements: the tool must have a near perfect radius and a virtually flawless cutting edge. The precision of the radius of the blade must be very high, so that both the high or low chip grooves will not cause the unaverage state of the metal scrap, so as not to affect the geometric shape, reduce the surface quality and the tool life, the precision of the end milling cutter used in the workshop should be at least 10mm. The circular end milling cutter with a diameter of 0.3mm is also used occasionally, with a radius accuracy of + 5 mm.
The cutting edges of chip removal grooves will inevitably have some trace chips, breakage or other irregular shapes. These defects show that they accelerate wear when touching workpiece. This situation will lead to rough roughness and shorten the service life of the tool. The service life of a tool is a very critical factor, because when the machine is unmanned, the workshop is entirely dependent on the End miller to work to the desired time limit.
Suppliers such as OSG and NS tools can provide tools that meet the above specifications, but their prices are much higher than those of standard tools. It is absolutely necessary to use this quality grade tool, and the cost should not be a problem. These tools are the basis of die processing, which can save the polishing process and the point by point trimming process of the mold. In the hard material milling process, it is a very important investment to add these tools.

What is a stamping die

Stamping die is a special process equipment for processing the material (metal or non metal) into parts (or semi finished products) in cold stamping process. It is called cold stamping die (commonly known as cold stamping die). Stamping, at room temperature, is a pressure processing method using the mold installed on the press to make the material pressure to produce the separation or plastic deformation so that the required parts can be obtained.

Performance of heavy wood saws with wooden keel

Multi chip saw is a tool for wood processing, and the requirement for this tool is relatively high. There is also the existence of a single saw, the function of which is the same as the multiple saw, but it can only be used for simple wood processing, so it can only be used in more difficult wood processing. And the demand for single saw is relatively low, because its role is relatively small, so in general, poor quality single saw can also be used.
But the requirement for multichip tools is high, because the main purpose of using them is to save materials and improve efficiency. Because the multi saw is made up of many saw blades, the surface of these saw blades must be smooth, otherwise it will be difficult to use. In addition, saw blades should be thinner, because too thick saws may not work well, and they will take up the place.
This tool is also very convenient and quick to work. First, put wood at its feed inlet and then wait for it to come out at the discharge port. Its efficiency is very high. * it can produce twenty to thirty square lumber, which is not available by other equipment.
Multiple saw has a variety of advantages, which is the main reason people are willing to use it, and our ordinary life can not be separated from it, its role is very important.

Multi saw is a combination of multiple saw blades, and a single saw is a single saw operation. The general requirement for a single operation is not very high, even if the quality is slightly worse. But the multiple saw is not the same, and the requirements of the saw blade are higher, but the use of multiple saws generally requires a comparison of wood saving and sawing. Small, the saw blade is very good.
Customized multi model square lumber sawing saws factory direct sale

First of all, we talk about the problem of the card machine. The card machine is usually caused by the improper operation of the workers. After the timber is cut down from the forest farm, it is ready to go through the branch and then pass the cutting to the multi saw. The nature of the wood determines its processing difficulty, the scar on the wood, the harder place, the workers if they have the Scars are always in the direction of the sawtooth, because the lateral hardness of the wood is uneven, and if the quality of the saw blade is not good, at this time the transverse sawblade can not unanimously cut the wood, it will produce uneven force and can easily be stuck to wood. Good multi saws generally use better quality saw blades, even if the hard scars can be very longitudinal, and will not encounter the problem caused by the uneven force of the saw blade. Again, the problem of wood sawing saw blade, generally burning saw blade after the equipment factory, manufacturers in the selection of multiple saw, do not pay attention to the quality of the problem, burning saw blade generally because in the sawing wood, heat radiation does not cause heat concentration in time. In order to avoid such a situation, the general multi saw will have a cooling device. The saw blade material used in good multi chip saws is conducive to heat dissipation, and there are cooling holes on the saw blades. The general multi chip saw will test its quality before the factory is out of factory. Consult the manufacturer when changing the saw blade. The surface of the processed wood is not flat, and there are many reasons for this situation: the wear of the saw blade will cause this situation, the spindle is loosened because of the problem of use, and the surface of the jacket of the saw blade is not smooth, and the problem will be produced without attention when changing the saw blade. Generally speaking, although many saw saw the technical requirements of the workers are not high, but the workers still have certain requirements, and the machine will be used by the people who will use it.

6 characteristics of news marketing

Network news is one of the earliest Internet applications in the development of China’s Internet. Its content and the increase of users have brought a broader market prospect in information recommendation, marketing and promotion, even more in-depth content production, interaction and communication.
News marketing is one of the ways to use the Internet news for the enterprise to publicize and marketing. It is favored by more and more enterprises because it can effectively integrate the means of news reporting and create the best communication efficiency. Whether it is the enterprise culture, brand connotation, product mechanism, or information in the communication industry, the news marketing can lead the consumption fashion and guide the purchase decision, which is very helpful to guide the market consumption. In a short time, it can quickly improve the reputation of the product, and shape the reputation and credibility of the brand. The functions and characteristics of news marketing can be roughly divided into the following six points:
One, high reading rate: the traditional advertising has made customers aesthetic fatigue. Most of them only cause resistance and antipathy, but people’s attitude to the news is different. Getting news is more like an indispensable part of daily life. If the marketing information is integrated into the news, it will improve the customer’s reading rate. It is better to promote the effect.
Two, high credibility: compared with traditional advertisements, customers prefer to believe in the contents of news, especially the news content issued by authoritative media.
Three, the conversion rate is high: the content has the depth of the people to see the news more patient, is beneficial to the enterprise to express the information more fully, the long piece of news will cause the audience’s thinking, can deepen the audience to the enterprise propaganda information impression, achieves the higher conversion rate.
Four, the optimization effect is good: the search engine algorithm is constantly changing, and it is difficult for a website to keep on the home page of Baidu, especially in the competitive industry, which requires continuous updating of the website optimization strategy. Because the marketing news information is published on the big news portal, and the search engine itself attaches great importance to these websites, the important content will get better ranking. Then, the coverage of search engines has increased, which will naturally bring more business opportunities to enterprises.
Five, persistence: a news will be kept for a long time when it is published on the website. Even if time does not show on the front page or channel page, it can be searched by a variety of search engines, and the news is more cost-effective in the long run.
Six, two transmission: the content of the general news portal will be considered high quality, so it will be reprinted by a lot of small websites every day. If the news of the enterprise is logged on to a large portal, it is likely to be reprinted on dozens or even more small sites. More people will be browsing, and will be two. The effect of secondary propagation is helpful to enhance the coverage of enterprise information in search engines. Of course, the key to the success of the news marketing is to find the embedded point and embed the information of the enterprise and product into the news, so as to achieve the effect of the spread of the potential.
Business media online is an Internet marketing agency specializing in news marketing. Whether it is written in soft writing or media release, it has a good grasp of high quality media resources, covering the front lines, NetEase, Sina, Sohu, Tencent and other front-line media resources, serving thousands of customers and highly praised by customers.
In addition, news marketing must stand on the third party’s position so that it can be more authentic. Whether it is artificially planning, or with the help of current hot spots, we must carefully design, let everything appear to be reasonable, let the user easily fall into the trap, so the marketing will come to an end.

The method of judging the quality of the external link

How to judge the high and low quality of the external link: the “outside chain” of the website, which is often mentioned by the general stationmaster, I believe that everyone will listen to the ear again, but it is undeniable that the role of the external chain on the various aspects of the website is also undeniable. Snapshot update frequency by the outside chain, web site keyword out chain, the number of pages included in the web site depends on the outside chain, but I want to say is not what the chain is good for the website, on the contrary, to do low quality external links is not as good as not to do. Then how can we judge the quality of the website’s external chain?
1, from a time perspective, the longer the external links are retained, the higher the quality of external links. Every day, the search engine examines the frequency of the content of each website, the construction of the external links of the website, the long time, the low quality of the external links will be slowly removed. Those external links that retain half a year, one year or even two years are undoubtedly the external links recognized by search engines, which is undoubtedly the external chain of high quality. But this kind of judgement skill is not very easy. This requires the stationmaster to observe and accumulate for a long time. Through daily observation of the external links snapshots of their websites, the number of external links to determine which are high quality external chains and which are low quality external links.
2, the second skill is mainly from the website itself as the starting point, by observing the snapshot and quantity of its own website to judge the quality of the external links of the website, and the method three is the extension of the two, that is, through the study of the external links of the similar competitive websites. For example, we do “mobile phone purchase” the key words, we can look at the same website, especially those websites with higher weights than their own websites, talk about the external links of their websites through the stationmaster tools, see where they have built the external links, through the contrast of the snapshots, we are easy to do. Determine which of the high quality external links.
3, as we all know, many websites, even if they are just opened, will be highly weighted if they are included in the search engine. This is mainly reflected in the websites of education, medical, industrial and GVM industries. Stationmaster in these industry Web site to do external links, although the degree of relevance does not necessarily conform to the content of the website, but once included, it is absolutely a high quality external link. This kind of website weight is relatively high, the reason is also very simple, because the content of these websites are original, the main reason is that this kind of website is related to the country, of course, it is not our personal stationmaster or other stationmaster can compare. In order to cater for the country’s policies, the website engine will even manually increase the weight.

Several standards of assembly line service

Now most of the production of enterprises can not be separated from the pipeline, the emergence of the pipeline not only greatly improved the production efficiency of the enterprise, but also promoted the rapid development of the pipeline manufacturers. Today, Xiaobian is going to tell you a few standards for assembly line manufacturers.
1, the reliability and stability of equipment is not only related to the quality of pipeline equipment, but also whether customers choose to use this equipment.
2, the equipment performance price ratio, the better the performance of the equipment, the price is naturally more expensive.
3. The operating cost of the equipment
4. Supply of accessories for equipment
5, assembly line manufacturers before and after sales service is also very important.
Assembly line manufacturers should ensure that users provide various technical services in the use of products. Adhering to the “professional, perfect, rapid, customer oriented” service principle, assembly line manufacturers should also provide a complete set of pre-sale and after sales services. Only by standing in the angle of the user to analyze the problem and solve the problem can the user be more assured of the use of the product, and it is also a kind of trust for the production line equipment of its own company.
