Packaging machine development trend of the 21st 1.Highly productivity. The productivity of the vacuum packaging machine from a few pieces per minute development to the number 10 ,thermoforming-fill-seal machine productivity up to 500/min or more. 2.Automation. 3.Standing alone multi-function can easily expand the scope of use. Achieve stand-alone multi-function must be modular in design,transformtion and combination of function modules,for different packaging machine. Representative products HESSER production plants in Germany BOSCH company belongs spindle round multi bag vacuum packaging machine,bag,weighing filling,vacuum sealed,and a variety of functions to be completed in a single. 4.Be composed of the production line.All the features concentrated in a single machine when a growing number of the functionality required marking a very complex structure,operation and maintenance is not easy,this time function can be different,and efficiency to match the combination of several machine successfully,more complete production line. The development status of foreign packaging machine: Germany German packaging machinery in the measurement of all belong to world-class performance in manufacturing technology,For beer filling production of complete sets of equipment production rate high degree of automation has good reliability.They mainly manifest in:Process automation of high production efficiency, meet the short delivery time and reduce the process cost;Equipment has higher flexibility and flexibility.Mainly reflects,in the production of flexibility structure flexibility and the flexibility of the supply,To meet the needs of the product upgrading;Using a computer and simulation technology to provide complete sets of equipment,Low failure rate can be remote diagnosis service;With less pollution to the environment, including noise pollution of dust and waste material。 Italy Italy in the production of packaging machinery, 40% are food packaging machinery,Such as candy packing machine for tea packaging machine, filling packaging machine and so on.The characteristics of the product is elegant appearance good performance price cheap.Italian packaging machinery industry is the biggest advantage is can according to the requirements of customers design and production,And can ensure well completion design production experiment, implement supervision and assembly adjustment and user demand analysis, etc. Our country packs the mechanical profession start in the 20th century 70's, and the 90's intermediate stages obtains the rapid development in the end of the 80's. Has become in the mechanical industry one of 10 big professions, regardless of is the output, in the variety, has all obtained the amazing achievement, packed the industry for our country the fast development to provide the powerful safeguard. At present, our country has become the world packing mechanical industrial production and expends one of great nations. Current our country food and a packing machinery prominent question is the new product development cycle long, imitates much, innovates few, not only this with designs personnel's state-of-art related, also concerns with the correlation profession development. The international advanced method utilizes the simulation technology, by the computer automatic synthesis three-dimensional model, will pass has occurred production line breakdown data feeds the computer, then will demonstrate the actual operating mode, according to will need to carry on the revision in front of the user, finally will consummate. The packing machinery took one product, its meaning is not merely the product itself material significance, but is includes the form product, the stealth product and extends the product 3 meanings. The form product is refers to packaging machine itself the concrete shape and the basic function; The stealth product is refers to the packaging machine the actual utility which provides to the user; Extends the product is refers to the packaging machine the quality assurance, the use instruction and the post-sale service and so on. Therefore the packaging machine design should include: Market investigation and study, schematic diagram design, structural design, construction drawing design, instruction for use compilation and post-sale service predetermined plan and so on.  The new packing machinery often is machine, the electricity, the gas integration equipment. The full use information product newest achievement, uses air operated separation transmission technologies and so on implementing agency, servo motor-driven, may cause the complete machine the transmission chain to reduce greatly, the structure is greatly the simplification, the work precision and the speed enhances greatly. One of key technologies has used the multi-electrical machinery dragging synchronization control technology. Actually grasps this kind of technology not very difficultly, only is some designs the personnel not to understand the packing machinery this trend of development. If beforehand our country packs the machine design is the imitation, the study stage, then we should have the innovation design consciousness now.  “十五” period, our country packs the mechanical industrial development to be rapid, in recent years imports the equipment all is domestic cannot make or the manufacture level is far from, may see our disparity from the import to be at. Food security problem whole nation attention. “十一五” period should enhance food security domain the science and technology and the equipment level, the development fast, in accurate appraisal food harms the factor the technology and the equipment, further researches and develops the pathogenic microorganism resistance, cause of disease prevention technologies and the preserve technology and the equipment and so on control. Food and the packing machinery form the profession already for 20 years, is opposite in food packing, a new profession. This 20 years also are the world technological development quickest times, the new technology applies unceasingly in the profession, but the domestic profession foundation is weak, technical and the scientific research lack of strength, its development relative lag, has towed food and the packing industry hind leg to a certain extent. Although overall development quick, but food packing mechanical industrial development is quicker. the goal is must reduce this space, catches up with the world advanced level for the food industry, for causes the packing great nation to make great strides forward to the packing powerful nation, provides the advanced technical equip, lets import the equipment the role which only plays in the domestic market appropriates lost articles fills a vacancy. This request domestic food and the packing machinery year development speed surpasses 18%, the new product output value rate achieves 25%. On the international packing and food machinery development is take the big customer request as the goal, the impetus correlation machinery development. The big customer request mainly manifests in the below aspect: One, is higher well to the production efficiency request. This may reduce the product the cost, satisfies the date of delivery. The high speed packaging machine request must have the correlation engagement with the first working procedure, does not have to transport the link, including the control engagement, the entire production line must achieve the inverted order according to the production and the packing working procedure arrangement to start, smooth engine off. If Leng Guanzhuang the production line makes something a matter of political line automatically from the plastic raw material to the drink fills installs, the big packing piles buttress completely automatically in seals up in the workshop to carry on. Two, may adapt the product renewal change. The packing machinery must have the very high flexibility and the flexibility, the production line permission the packing material size may change in certain size scope. Because product life cycle far short in useful life of equipment, change product and packing not as for replacement expensive packing production line. Three is the equipment common breakdown rapid elimination. The solution inputs the computer in advance, when the equipment appears the common breakdown may diagnose voluntarily, also may implement the long-distance diagnosis to eliminate the breakdown abreast in row. Four, the request has the automatic diagnosis function. On the one hand may automatic diagnosis packing material thickness, degree of hardness, the counter-tension and so on, feed back through the computer to the manipulator adjusts the movement scope, does not guarantee the resilience. On the other hand, each different product, like shape each different chocolate or the dessert and so on, install to the identical box in, its arrangement is orderly. The production line transmits the product is a disorder, the available probe head scanning, determined the different shape the material position, feeds back again to the different manipulator, it can accurately unmistakably puts in the goods according to the accurate position and the direction in the tray, moreover, removes the manual control quickly the vision and finger weariness. Five, may reduce the environmental pollution as far as possible. The reduction including the noise, the dust pollution, and reduces the reject as far as possible, this point especially is important in the food processing process. Food raw material when processing not only harvests the main product, like corn processing, product besides corn starch, but also has the corn oil, the salad oil, the margarine, the glucose, the corn protein and the feed, as well as the sewage treatment and so on produces the entire process, is the automation. Does not have the reject, not to pollute, other product value has surpassed the corn starch greatly the value. Along with the science and technology development and the market competition aggravating, the customer demand more and more is also high. This kind of demand manifests in following several aspects: One, enhances the production efficiency, satisfies the date of delivery and reduces the production cost the need, to some products, but also requests the packing machinery and the production machinery links up; Two, is meets the product renewal change need, the packing machinery must have the high flexibility and the flexibility; Three is when the equipment appears the breakdown, the request can carry on the long-distance diagnosis service; Four, favors the environmental protection, the noise, the dust and the reject are few; Five is the equipment purchase investment are as far as possible few, the price must be as far as possible low. Therefore, must certainly in the market investigation and study foundation, the full understanding, analyze the user earnestly the demand, the definite packaging machine should complete the function and each technical specification, draw up the preliminary principle design proposal. The modern packaging machine design process should include: The market investigation and study, the user demand analysis, the packaging machine function determination, the feasible proof, the formulation design proposal, the user benefit analysis, the plan feasible proof, the schematic diagram design, the structural design, the construction drawing design, the prototypical manufacture (hypothesized manufacture), the technical confirmation and the construction drawing revise, the formulation post-sale service predetermined plan and the long-distance diagnosis plan, the improvement design, the serialized design and so on. . The market investigation and study is the foundation work which all packaging machines design. Without the market investigation and study, we do all design work all possibly is equal to the zero. The market investigation and study, may according to the policy guidance, the profession supply and demand information, the expert analyze, the profession unfolds clues and so on meeting, technical meeting, found the user the demand information, after and reorganizes the analysis, the definite packaging machine should complete function. In the principle project design process, first must understand fully the related information product, the electronic products function, understood the air operated part the performance, and uses to simplify the mechanical drive system, but also may use the multi-electrical machinery dragging to reduce the mechanical transmission chain. Regarding the essential mechanical drive system, should make the best the modernized design method, in to product functional analysis foundation in, through innovation idea, system modelling, mechanical analysis, dynamic optimization, thus obtains the best design proposal. The technical design is the principle design structurization, definite spare part quantity, the shape, the size, the material and so on, the essential components carry on the power computation, the power computation, the strength calculation, the rigidity computation to the major component in. When system design, must consider the entire packaging machine system comprehensively the layout, the movement coordination, the modelling design, the human - machine environment as well as the packing transportation and so on. The modular design is one advanced design method, its core thought is divides into systematically according to the function certain modules, the identical function unit designs the packaging machine in has the module which the different performance, may exchange, through the module different combination, causes the packaging machine multi-purpose, the seriation. Uses this method the merit is: (1) makes the packaging machine renewal speed to speed up. Because of the new type substitution, often is the partial improvement. The vanguard technology introduction corresponding module, compared with easy to realize the partial improvement; (2) reduction design cycle. After the user proposed the request, only must replace the module, or the design manufacture partial modules, then obtain the new type, meets the user need; (3) reduces the cost, is advantageous for the service; (4) performance stable reliable. Because time module design, to the packaging machine function division and the module design, has conducted the careful research, has guaranteed the module performance, for example: Cam gear, servo, examination system, transmission system, control system, measurement organization, yummy treats organization and so on. . Other packing machinery seriation, modular profession standard, also arrived should formulate, the packing machinery has become our country one of ten big mechanical professions, but serialized, the modular profession standard formulation will certainly to promote our country to pack on the mechanical profession cross new stair.The significant difference is that packaging plays a different role in a market where rice will sell solely because it is available. In the North American market, the consumer may be confronted by five different companies offering rice in 30 or so variations. If all the rice is good and none is inferior, how does a seller create a preference for his particular rice? How does he differentiate? The package plays a large role in this process.The package-intensive developed countries are sometimes criticized for over packaging, and certainly over-packaging does exist. However, North Americans also enjoy the world’s cheapest food, requiring only about 11 to 14% of our disposable income. European food costs are about 20% of disposable income, and in the less-developed countries food can take 95% of family income.
