The first high-speed shaped auto-sequence automatic packaging production line developed in China has a high degree of automation. It can spray a unique code on a single product with a jet printer in sequence, which overcomes the problem of automatic sequential packing of shaped bottles for the first time, saving manpower. Increased labor productivity, reduced production costs, improved product quality, and met the growing market demand.

It is the first independent researched and developed high-speed automatic sequence case packing line for abnormal shaped bottles in China. With a high level automation, unique code can be printed sequentially on individual product by ink-jet coder. The difficult problem of automatic sequence Case solution for abnormal shaped bottles is solved for the first time. The solution saves manpower, increases labor productivity, lowers production cost, improves product quality and meets

As a traditional packaging method, corrugated carton packaging has been widely used in the field of product packaging at home and abroad. According to statistics, corrugated boxes accounted for 66% of all packaging materials used. Especially in recent years, with the improvement of product brand awareness and the rapid development of production scale, intelligence, and automation level, in the packaging form processing, the environmental protection, anti-counterfeiting, anti-smuggling, commodity logistics management and other aspects have been proposed. High requirements.

The so-called automatic sequential packing, mainly in the production process of the product, sprays a unique code on the individual products with the printer in sequence, and automatically loads them into the package in order. After packaging, individual products are also sprayed (or affixed) with a unique code on the package. The encoding of a single product has a one-to-one correspondence with the encoding on the box and is associated and stored by dedicated software. When the goods are sent from the warehouse to the dealer, the outer box code is sequentially input into the computer through the scanning device and associated with the sales information. In this way, a single product code and an export code and the like form a very close relationship with the shipping information, that is, form an identification system. Market personnel can accurately find the original place of sale of the product by inputting the code on a single product or the code on the outer box of the product through the Internet or by telephone. This promotes the warehousing information management of the product to be more standardized and efficient, thus effectively Solved the problem of market dumping, which is also a symbol and symbol of a mature enterprise.

To solve the problem of market dumping, we must first meet the automatic order packing, and we must solve the corresponding technical problems from the packaging equipment. China's packaging equipment industry, due to late start, low starting point, small scale, its overall level is 20 years behind developed countries, especially in the automatic sequential packing technology, is still blank, is just starting in the international arena, there is no reference experience of. Therefore, the development of automatic order packing equipment for shaped bottles suitable for the needs of enterprises has been forced into the eyebrows, and the domestic market has a large demand space.

In order to reduce the labor intensity of employees and improve production efficiency and product quality, Jinpai Co., Ltd. reached a consensus with Guangzhou Guangfu Packaging Machinery Co., Ltd. in May 2005 to clarify that the two sides jointly developed the first automatic high-speed shaped bottle in China. Box production line. After more than one year of continuous research, development, exploration and experimentation, we solved one technical problem after another. Finally, it was successfully developed in January 2007 and installed in the 12,000bph filling production line of No. 10 Health Wine Phase I of Jinpai Co., Ltd. So far, the packaging production line has been running continuously for more than four months in the peak season of production during the peak season, and the use is good (single packaging production line can reduce the number of employees to 8 to 10). In the third quarter of 2007, Jinpai Co., Ltd. plans to add 11 similar automatic sequential packing production lines.

The technical innovations of the automatic sequential packing production line for high-speed shaped bottles are as follows:

First, 125ml Chinese spirit bottle characteristics

The arrangement is 3×8, and a 3.7 mm thick protective partition is added between the bottles after packing.

Second, the composition of 125ml China Jinji automatic sequential packing production line

The high-speed shaped bottle automatic sequential packing production line (line efficiency 12,000bph) must be equipped with system equipment with matching performance, appearance and technical requirements. The equipment of the packaging production line consists of a fully automatic unpacking machine, a drum boxing machine, an automatic sequence packing machine, an automatic sealing machine, and an automatic sequential spraying (paste) code machine (the outer box code corresponds to the inner code of 24 bottles). The entire production line is controlled by PLC computer, photoelectric detection, engine-air linkage, and human-machine interface display.

1. Automatic box opener

Because the outer packaging of the 125ml China Jinjiu automatic sequential packing production line is made of three-layer corrugated paper, the paper layer is thinner. After the nail box, it is easy to cause deformation due to factors such as strapping, transportation, weather humidity, etc. It is the deformation of the front and rear wings and the wings on both sides of the bottom of the carton, which increases the difficulty of unpacking and sealing. Therefore, through the test, the design has added four sets of correctors, which effectively compensates for the influence of the carton shape on the carton forming. At the same time, the design and development of the carton bottom seal shaper, the seal is smooth, the seams are flush, no overlap, no bell mouth.

2. High-speed shaped bottle automatic sequence packing machine

According to the characteristics of packaging containers and packaging outer boxes, the technical innovation research and development process of high-speed special-shaped bottle automatic sequence packing machine mainly solves the following four problems.

(1) Realizing high-speed automatic bottle handling device

According to the bottle type shown in Figure 1, to achieve orderly packing, first of all, to achieve an orderly bottle, after repeated research and simulation tests, the following bottle-washing mechanism is used:

When the labeling is completed and the sprayed bottle (finished product) is transported from the single-row bottle chain link, when the swinging bottle separator 2 is passed, the counting detection switch on the above is counted and detected by the passing bottle, each passing through a group The bottle (3), the counting detection switch sends a signal to the electromagnetic reversing valve to control the reversing of the cylinder 1 and the swinging disintegrator 2 swings a station under the control of the sub-cylinder 1 to the double-row bottle chain The second bottle is delivered; in this way, the orderly bottle can be achieved. Practice has shown that such an orderly bottle can reach 15,000 bph.

After the bottle is divided into two by swinging the bottle splitter 2, it enters the arranging bottle and is positioned by the bottle partition 4. The special customized bottle partition 4 can make the bottle spacing error not exceed 1.5mm, thus ensuring the catch The accuracy of the bottle. When both rows of bottles are in contact with the detection switch 5, the detection switch sends a signal to the servo drive motor, and the servo drive motor steps through two stations. When the detection switch mounted at the end of the alignment bottle detects that the number of bottles has reached the setting. When the quantity is reached, the bottle grabbing instruction is issued, and the bottle grabping and shifting operations are performed.

It should be noted that the number of the bottle splitting device 2, the arrangement of the bottle and the positioning bottle of the bottle are determined according to the shape of the bottle to be transported and the arrangement of the bottles, and the arrangement of the bottle is provided. The servo motor relies on the positioning detection, so that the multi-row bottle chain link only moves the distance of two chain plates at a time (that is, the width distance of the two rows of bottles), and the detection switch sends a signal to the electromagnetic reversing valve to control the pressure bottle cylinder 3, and the pressure Double-row bottles on the double-row bottle to ensure that the double-row bottle does not have a bottle misalignment during operation. This mechanism is suitable for regular bottle types, especially for high-speed automatic sequence alignment of shaped bottles.

(2) Achieving special-shaped bottle pneumatic mechanical gripping bottle

The traditional bottle grabbing is the use of airbag grippers. However, for the bottle type, the outer diameter of the air bag type gripper exceeds the minimum distance between the bottles, and therefore, this method is not preferable.

After careful study, this machine adopts a new pneumatic mechanical bottle grabbing method:

The bottle grabbing mechanism is composed of a chuck 1, a fixed shaft 2, a swing shaft 3, a connecting shaft 4, a connecting rod 5, a mounting seat 6, a pull rod 7, a sliding plate 8, a cylinder 9, and the like. The mount 6 and the slide plate 8 are integrally connected and powered by a separate cylinder 9. When the cylinder inflation rod is extended, the pull rod 7 is pushed downward to move downward, and the upper end of the chuck 1 is moved outward by the connecting shaft 4, the connecting rod 5 and the swing shaft 3, and the chuck 1 is connected to the mounting seat 6 by the fixed shaft 2. Therefore, the chuck 1 is rotated by the fixed shaft 2, and the lower end of the chuck 1 is swung inward, so that the chuck 1 clamps the bottle. When the cylinder is reversely inflated, the collet 1 releases the bottle by the reverse action of these workpieces. The chuck 1 adopts a metal base body, which is coated with wear-resistant rubber, and adds ribs at the contact portion with the bottle to increase the friction force and improve the success rate of the bottle grabbing; the chuck 1 can change its specific shape according to the bottle type. Structure, adapt to various bottle type production needs.

(3) Realize non-destructive packing

The design of the machine minimizes contact with the trademark, and all parts in contact with the trademark are made of special materials and special treatments, so that the label is well protected throughout the packaging process.

(4) Adopt more stable and reliable power

The drive system adopts a servo motor to realize the reciprocating movement of the bottle-carrying box through the sprocket, and under the action of the unloading cylinder, the operation is stable, the adjustment is convenient, the accuracy is high, and the service life is long.

3. Automatic sealing machine

The automatic sealing machine uses pressure sensitive tapes such as PVC and BOPP as sealing materials. It adopts flexible belts and drives up and down synchronously. It is equipped with supporting rollers. It has good mobility and the sealing is smooth and accurate.

4. Bus control

The bus control requires a full-line rated production capacity (line efficiency: 12,000 bph) to smoothly implement automatic sequential packing. The whole line of bottle and conveyor systems runs smoothly, smoothly, with low noise, no jumping, and no stringing. All electrical control components and pneumatic control components are selected from high-quality brands. During the conveying process, the bottles are not blocked, the bottles are not squeezed, the bottles are not broken, the labels are not damaged, and the speed is automatically controlled. The production links are matched with each other. When a fault occurs in a certain link, the front-end system will slow down or stop, and the latter section will continue to run.

In short, after several months of full-load production, this first automatic sequential packing production line that fills the domestic gap has undergone a rigorous test, which proves that the whole line of technological innovation and research and development is successful, which also brings a package to China's packaging industry. A new concept. China's first high-speed special-shaped bottle automatic sequence packing production line was successfully put into production and equipment system acceptance at Jinpai Co., Ltd., and the automation degree of Jinpin Brand Co., Ltd. packing production line was greatly improved, and the domestic enterprises firstly conquered the special-shaped bottle automatic packing. Puzzle. Greatly saved manpower, increased labor productivity, and reduced production costs, with a single shift capacity of 5,000 pieces. At the same time, the fully automated production method has also improved the product quality and satisfied the expanding market demand.
