Mechanization Promotes Progress of Packaging Industry

The 19th century reporter and writer Loveson Karl once said: "The bigger the change, the more it can promote change." This phrase can be used to describe the history of the development of packaging machinery. Despite remarkable changes in control technology and the acceleration of progress in the last century, the automatic packaging industry has remained stable. Like the early machinery, today's packaging machinery is still in order to meet the needs of labor-saving, cost-saving, stable quality, high output, fast, accurate filling, anti-theft and anti-counterfeiting. Some regulations formulated by the local government and the federal government, such as the requirement for accurate filling of weight, and the requirements for the packaging of commodities such as anti-pollution, anti-corrosion, anti-insect and anti-striking, have played a major role in the innovation of packaging machinery. Material advancements also have a major impact on machine design. For example, many of today's machines for packaging flexible materials cannot be invented without the polyethylene material of cellophane and its substitutes. In fact, Robert Kessellinger, president of New Jersey's Korsler Packaging Consultancy, believes that "the change from a monolithic package to a small unit volume package and the accompanying increase in self-selected goods is also an influencing factor. Most of the overall packaging is automated, but semi-automated machines and manual packaging are still widely used, even in some developed countries.The 1948 Encyclopaedia of Packaging mentioned that "by using some semi-automatic production lines, some factories can also Efficient production of certain goods.” This formulation is still very realistic today. Since the beginning of the 21st century with the introduction of Ichiro (20th century), the machine has made great progress in terms of production speed, flexibility, and control, and the control technology has gone from machinery. The development of control to electronic control, authoritative of the packaging industry, Ken Galerman, former president of Orden, Buffalo, NY, pointed out that “Today, more than 50% of packaging machinery is electronically controlled.” Dennis Versworth, president of Machinery Manufacturing, added: "The program control mechanism has changed , Mainly due to its fast response speed. "In addition, "the servo launcher has also exerted a huge impact." The Eastern Sales Manager of Swats also pointed out that "it can reduce mechanical lines and revolutionize full automation. 1 The earliest development of the earliest packaging machinery appeared in the 19th century, one of which was the pressure labelling machine introduced by Conneg's Standard Packaging Corporation in 1893. The successful use of the filling machine around 1900 enabled more products. In the same period, Butt introduced a can labeling machine that uses kerosene to heat the adhesives for labeling.The earlier weighing machines also appeared in the first decade of the 20th century and were used mainly for packaging chewing gum.
Other early-mechanical party juntas included South Carolina's surface parcel charter, New Hampshire's semi-automatic stripe labeler, and a molding-cut-knot confectionery packaging machine invented by Henry Kemp. In addition, there are some cigarettes, tobacco packaging machinery. However, manual packaging is still very common in the first half of the century. The Smith Brothers is known for assembling the first automated packaging line in 1916. By using this production line, enough cold medicine can be produced to meet the needs of the market at that time. In the 1930s, the pace of mechanical progress accelerated, and machinery manufacturers began to install housings on the surface of machines. This is the unification of the high speed of machine operation and production safety under legal requirements. This type of production line packaging machine is greatly favored by manufacturers. They hope that they will leave the visitors as deeply impressed as possible. One example is the vacuum milk filling-filling-capping machine used by Crohn. The filling machine greatly increased the filling speed and accuracy, and replaced the cork with a seal. Labeling also uses automated devices, such as the Bonnie labeler manufactured by the New Jersey Machinery Plant. Other early machines also included automatic volumetric filling machines for filling dry goods, cellophane packaging machines for packaging carton boxes, and automatic carton strapping machines to reduce packaged health and beauty products. 2 The highly effective 4040s Modern Packaging magazine in March 1952 stated that "With the advent of World War II, the packaging machinery industry must produce machines capable of packaging a variety of products. These products must be produced at the fastest possible speed. The production and packaging of every component that may be subject to defamation in order to meet the needs of the wartime, the lack of labor at this time also exerted unprecedented pressure on the packaging mechanization.” The increase in self-selected retail commodities also stimulated the prepackaged goods, It also promoted the development of the machinery industry. Innovative products from this period include the first thermoplastic labeler introduced by New Jersey Machinery in 1946. The machine uses a viscous outer label body, which is heated to increase the viscosity for labeling. Therefore, different ambitions need to be prepared in advance glue and paste it on-site. As a result of rising production costs, this labeling mechanism has caused a slight increase in the price of labels. Thanks to the use of hydraulic and electronic weighing controls, a machine called Hattrik first appeared. It was possible to fill lightweight, fragile products such as potato chips and biscuits into cartons, using flexible materials. The packaging machine also made its debut. It was able to package some fragile products like noodles. The fully automatic carton packer serves as a secondary packaging machine and can pack 240 containers per minute. The calibration device simplifies and accelerates this change. Some packaging machines also have the ability to add tear strips. The glass bottle washing machine began to give way to the air cleaner, so that the automatic filling machine at that time could reach a filling rate of 300 bottles per minute, and the capping machine was also on the production line at the same time. In the 40's, vacuum packaging machines emerged. This machine, which was invented and patented by a milkman on the West Coast in the 1930s to package coffee, is now being used by standard packaging companies to produce and process vacuum-packed bacon that is made of flexible materials. In 1947, this kind of smoked meat was very profitable. 3 The fruitful 50s of the 1950s was a period of great success in the development of packaging machinery. This was transformed from wartime technology to civilian use. A large number of traditions and new types of packaging materials have emerged and unprecedented demand for consumer goods has been determined. Lack of labor, shortage of supplies, changes in the market, and shortage of skilled workers have greatly promoted the development of the machinery industry. At the same time, a large number of material substitutes for packaging different commodities increasingly require flexible packaging. In January 1951, Beechcraft launched the first vacuum glass bottle. By the late 1950s, baby food was packaged on the production line at a rate of 600 bottles per minute. Soft plastic and hard plastic began to appear. By 1958, all manufacturers producing form-fill-seal machines had introduced machines that could be packaged with polyethylene film materials that required thermostats and varistors to control the temperature during sealing. In 1959 Heinz company used a constant temperature of 200°C to pack the optional ketchup. During this period, the wire-wound chassis stapler reduced the length of the nail box by half. Other carton sealing processes have also been automated. In 1951, Florida ABC Packaging Machinery produced a packaging and sealing production line that integrated the packaging of melt boxes and packaging. Carton packaging is also automated. In the 50's, Swarth developed the first fully automatic cartoner. This kind of machine that can pack 30 boxes per minute has been used until 1996 by Anke Ben Company in Texas. Another noteworthy development is the emergence of mechanical devices such as press-fitting and carton sealing, and for the first time electronic control. Another new type of label sticking method called the thermal conversion method has also been successfully developed. This rotating machine can add 150 labels per minute on the container or film. At this time, modified atmosphere packaging is also used in large-scale commercial applications in cheese production packaging. 4 The packaging materials innovation of flexible materials in the 1960s and 1960s was mainly on plastic packaging, especially on flexible materials, with high speed, economy, and strong adaptability. As glass was replaced by transparent plastic materials, ABC designed a single-head arrangement for transporting lightweight packaging containers, and Stardard-Knapp developed a plastic bottle unscrambler, which was the first to use in inflatable packaging for coffee packaging—filling. - The sealing machine was later extended to the packaging of other products. Shrink packaging has also begun to spread widely. A variable shrink packaging machine developed by Wilderne, New Jersey, uses thin film wrapping and covering to package mats and mats. The 1970s marked "the arrival of mechanically flexible manufacturing, advanced controls, ease of operation, low repair rates, good durability, and high speed and precision of the mechanical age." The 10th issue of Modern Packaging magazine in 1969 so presaged the 70s packaging The characteristics of mechanical development. At the same time, more emphasis on safety also adds protection devices, interlocking devices and some warning signs to the mechanical design. In 1971, a Japanese company designed a multi-head combo weighing machine. The American Heating Control Co., Ltd. also produced such a machine, which has modernized the pepper weighing process. It can replace the whole enthalpy by weighing separately, allowing the machine to filter out a set of combinations that are closest to the target weight. Microcontroller replaced the hardware electronic control system and improved its efficiency. Digital technology has become a new choice and has grown. Such as the use of fluorescent ink, it can make the printed code invisible to the naked eye, but through the scanning of ultraviolet light to identify, identify and determine the packaging. The widespread use of polyethylene plastic bottles has had a tremendous impact on the packaging machinery that package some relatively less robust containers, such as the design of filling machines, capping machines and conveyor belts. Carton packaging, due to the use of hot melt adhesives, reduced press time, can also reach 700 packaging speed per minute. 5 Microcomputer control has been widely adopted for several decades with the development of micro-control technology. Higher and higher mechanical precision, higher degree of automation, the more durable. As more and more urgent requirements are made by consumers, some molding-filling-sealing machines have appeared in succession and can complete the packaging of film and seal tearing materials on the production line at one time. The large number of inflatable packaging machines in this period made it possible to simplify the flexible packaging of some cups and trays. Inkjet printers and dot matrix printers can print readable bar codes on porous substrates such as corrugated cardboard boxes. At this time, people are paying more attention to automation at the end of the production line, such as carton packaging and stretch wrapping. The first robots came out. Due to the occurrence of Tylenol in 1982, anti-theft packaging has received more and more attention. For most of the 80's, the emphasis was placed on improving the speed and efficiency of anti-theft packaging equipment. In the pharmaceutical market, due to the loss of drug labeling incidents, the FDA urged people to use a machine monitoring system to detect the accuracy of the label. In the 1990s, touch-screen computer controls were widely used. Make a series of information, such as the status quo of the machine, instruction settings, error correction tips and maintenance needs can be seen at a glance. Some machines even have self-diagnosis and adjustment capabilities. Today, in many respects, computer-controlled machines, especially the control of filling machines, may supervise the operation of the entire production line. Reduce costs and improve the use of control robots in the area of ​​loading and unloading packaging. Examples include the loading and unloading of cartons, cartons and pallets. The fast and program-controlled functions of the computer greatly simplify human supervision of the machine, increase production and reduce costs. For example, the high-speed blister packaging production line launched by Yuman Packaging Machinery Co., Ltd. in New Jersey makes the production line and the packaging line as one and can better ensure the collaborative work among various processes, and truly achieves the electromechanical integration. In the labeling, printing and pasting machines are widely used, and the latest machines can automatically print and paste 4-color labels. In fact, in the autumn of 1999, there emerged a new type of machine in which several printers simultaneously printed labels and can embed active strips in the labels. So what will the next new innovation bring to the packaging machinery? What we can foresee is that flexibility, high speed, and high efficiency in reducing costs are still the requirements of the packaging industry. Computer control, robotics, and bar code labels will be widely used. One of the most significant changes will come from the development of digital printing, which will eventually enable the implementation of batch printing packages on filling lines. In addition to this, one thing is certain: the packaging industry will continue to maintain its advantages and innovation will continue to promote the development and change of the packaging industry.
