Liquid packaging multi-functional vs single high-speed machine

the materials of liquid packaging cover all aspects of our life, such as alcohol, beverages, dairy products, vegetable oil, condiments in food, detergent, shower gel, cosmetics, pharmaceutical preparations, pesticides in daily chemical products, etc

liquid packaging adopts different filling methods and filling technologies due to different packaged materials, such as isobaric filling, negative pressure filling, atmospheric pressure filling, pressure filling and weighing filling

liquid packaging containers can be glass bottles, plastic bottles, metal cans, and the sealing method can be the gland of the crown cap, the screw cap of the threaded bottle mouth, or the double crimping and sealing of the can

liquid packaging technology first develops to a single high-speed type

when the equipment manufacturer accepts the user's order, it usually requires the customer to provide filling materials, packaging containers and bottle caps. During the acceptance of the equipment, it will also use the returned sample bottles and bottle caps provided by the customer for debugging. In order to regulate the consistency of containers and bottle caps, relevant national and industrial standards are also formulated. Usually, a conventional high-speed packaging line is only suitable for one bottle type. For example, beer bottles had only 640ml and 355ml glass bottles in the past; The geometric dimensions of the two pieces of aluminum cans have never changed much. All these provide the basis for high-speed and reliable filling. The beer filling machine with the maximum packaging speed of 60000 bottles/h and 120000 cans/h cans has been launched, and the production efficiency of the equipment has been greatly improved

many consumer goods rely on the attention of the audience to improve the competitiveness of the market. The update speed of content is far lower than the continuous change of packaging containers, which is particularly prominent in the beverage industry and daily chemical industry. The traditional high-speed production line suitable for mass production can no longer fully meet the needs of enterprises. Enterprises must find new production technology to adapt to the market changes of multi variety and small and medium batch products. The multifunctional design of liquid packaging equipment came into being

filling machines suitable for a variety of bottle types

relatively early in Baijiu and beverage production enterprises, some small enterprises have proposed to use glass bottles with different shapes and external dimensions in some low-speed filling machines in order to increase the variety of packaging, so a small filling machine sometimes needs to be equipped with three or four sets of star wheels and guide plates, and the filling cylinder and sealing device need a mechanical lifting mechanism to meet the needs of customers to change bottle types. The mechanical replacement and adjustment of this type of bottle generally takes a long time

plastic bottles are light in weight, can reduce transportation costs, and are convenient. The growth rate of double clutch transmission and stepless transmission has exceeded 20%. Consumers carry them, reduce damage, and save packaging costs. They are widely used in liquid packaging. Among them, carbonated drinks, water drinks, tea drinks and fruit and vegetable juice drinks packaged in PET bottles have accounted for more than 80% of the total output of beverages. PET provides a broad design space for bottle designers, which can strongly attract many consumers and form the mainstream of market consumption. These advantages make pet bottle packaging gradually replace glass bottle packaging

the wide use of plastic bottles in the field of liquid packaging provides a basis for the convenient conversion of bottle types

pet bottles generally have bottle mouths with the same specifications and sizes, which can realize air conveying, bottle mouth filling and sealing. In this way, the bottle type can be replaced only by replacing the star wheel and guide plate, and rapid loading and unloading is also possible. The traditional packaging of detergent, shower gel, cosmetics and other daily chemical products is PVC bottles and PE bottles. Many daily chemical products are basically homogeneous, and the biggest selling point of their market is often on the outer packaging. It is the pursuit of enterprises to display the corporate image and unique exquisite packaging. They produce distinctive packaging containers at economic cost and develop their own unique packaging, Packaging containers and slightly changed products are constantly replaced on the filling line. Bottle types with various specifications can be designed and produced in a short time

liquid packaging is basically a special machine due to different filling materials, different specifications and shapes of containers, and diversified sealing methods. In particular, small and medium-sized enterprises are characterized by a large variety of products and small batches. After nearly 20 years of introduction, digestion, absorption and innovation of packaging technology, packaging machinery has reached modular design. By increasing the proportion of general and standardized design, the general and standardized components of equipment are increasing, and a high degree of professional production, so that the serialized development of equipment can be realized, and the products can meet the needs of users, shorten the delivery period of equipment It is extremely beneficial to improve the reliability of equipment operation

this technology trend provides the basis for the versatility of equipment and Rapid NC conversion

Rapid NC conversion of production line

the industry consistent and universally applicable packaging equipment design platform, after meeting the most basic practical needs, special design enjoys standardized automatic control, which can enable customers to benefit from the solution combined with their special application requirements, forming the design concept that the equipment can carry out rapid NC conversion, so as to realize the versatility of the equipment

a complete packaging line for beverages, dairy products, pharmaceuticals, daily chemical products should generally include several processes such as destacking, bottle sorting, transportation, bottle washing, filling, sealing, labeling, packing, box transportation, stacking, as well as the detection between various processes in the production line. Packaging containers and products are often replaced in one packaging production line, which brings certain difficulties to equipment adjustment and reliable operation

the production line with the function of fast numerical control and fast conversion can be regarded as the equipment tailored to the packaging needs of users. It is a general equipment for this special equipment to carry out packaging production in an enterprise. It can realize the replacement of packaging materials, bottle types, trademarks, cartons and pallets

the ideal NC fast conversion has been able to input all parameters of several packaging methods, including packaging products, bottle type, filling volume and packaging capacity, into the CPU of PLC (programmable controller). Except for the parts that must be replaced, the rest are realized by adjustment. The PLC of the production line is designed with the replacement program of the production line, and the adjustment of all programs is completed by preset without any change of control circuit. Complete the adjustment of the equipment, create parameters according to the size and shape of the new container to be filled on the touch screen displayed by the man-machine dialogue, select the required setting, and confirm. At the same time, all parameters of PLC have the possibility of modification and addition. The adjustment of this transformation should be discontinuous

the less the number of parts that must be changed, the better. The changed parts will be installed by positioning pins, clamps, scales or digital displays without adjustment. In order to simplify these adjustments, these interchangeable parts are uniformly numbered according to the specifications of specific containers, and these numbers will be stored in the PLC

in order to make the working procedure simple and correct, all the changed parts of each bottle type are arranged in the same color sequence. When the product, bottle type, trademark, carton and pallet are replaced on the production line, the PLC change program can generally prompt the position, quantity and installation method of the changed parts to be replaced

except for the high one-time investment cost, other indicators are better than the conventional single high-speed production scheme

it is precisely because of the increase in equipment investment costs that equipment manufacturers restrict the research and development of rapid conversion production lines. The main reason is to consider the capacity of the market and the economy of user investment

the economy of multi-functional equipment every experimental machine needs a series of operating standards

the development of automatic control theory and the wide use of computers have laid the foundation for the emergence of new technical solutions

CNC multifunctional liquid packaging production line with rapid conversion function has high equipment utilization rate and flexible production, which can respond to production changes. When the market demand or design changes, there is no need to change the hardware structure of the system, and the equipment has the flexibility to produce different products. Because it has obvious economic benefits over traditional technology in solving multi variety, small and medium-sized batch production, with the intensification of international competition, both developed and developing countries pay more and more attention to the development of flexible technology

the multifunctional design with rapid numerical control conversion is easier to realize on the small packaging production line

it is reported that the rapid conversion equipment for changing the bottle type of foreign packaging machinery first appeared in the field of cosmetics and drug packaging. As mentioned above, cosmetic bottle packaging is updated faster, and this market demand triggered the development of multi-functional packaging machines. There are basically two ways of fast conversion. Some parts can be changed quickly without tools, such as the star wheel and guide plate of the filling machine; The other is the lifting and lowering of the filling cylinder, and the adjustment of the labeling machine, the packing machine and the stacking machine. PLC controls the operation of several servo motors to adjust to the required position

whether a liquid packaging production line should have the function of rapid conversion, that is, whether the product is a single high-speed type or a multi-functional type, depends on the needs of users and its economy

the versatility of large production lines may sometimes not be economical

take product variety change as an example. The filling valve of filling aerated beverage filling machine is more complex than that of filling non aerated beverage filling machine, and the equipment cost is high. An enterprise mainly produces aerated beverages, and occasionally produces a little non aerated beverages. It can purchase an aerated beverage filling machine to fill two products; On the contrary, if we mainly produce non aerated beverages and occasionally produce a little aerated beverages, if we configure the production line according to the aerated beverage filling machine, we may purchase a non aerated beverage filling machine and configure a small aerated beverage filling machine at the same time, which may be more economical than the latter

take the replacement of product bottle type as an example. The change of the shape and size of the drug or cosmetic bottle is relatively small, and it is easy to realize the rapid economic conversion. If the overall dimension of the bottle changes greatly, it needs to be considered otherwise. For example, a liquid filling machine should use two types of bottles with a diameter of 50mm and a diameter of 150mm. Generally, small-sized bottles have fast filling speed, small bottle spacing and high equipment speed; The filling speed of large-size bottles is slow, the bottle spacing is large, and the rotating speed of the equipment is low, because the rotating speed of the equipment should be designed according to the small bottle type, and the bottle spacing of the equipment (usually interpreted as the modulus of the equipment) should be designed according to the large bottle type, so the economy of the equipment is afraid to be greatly reduced. Bottle sorting equipment with high production capacity can not tolerate the design with large changes in bottle shape

for labeling, packing and stacking equipment, the conversion of packaging is mainly realized by adjustment, and the realization of a new positioning dimension is implemented by the servo motor, and its accuracy is beyond doubt. However, the stability of positioning after the realization of the position puts forward a reasonable recycling method of old asphalt and old aggregate and the design method and reliability of recycled asphalt composition depend on the rigidity of the locator, which is also an aspect of increasing investment for large equipment. Therefore, for developing countries or developing enterprises, when the current labor cost is still relatively low, sometimes they prefer to use mechanical adjustment and mechanical replacement. The disassembly, installation and adjustment of many replacement parts will take more time, but compared with CNC fast conversion equipment, it can reduce investment

but the multifunctional packaging equipment with the function of rapid assembly and replacement has
