The German government put forward the concept of "Industry 4.0" in the "German High-Tech Strategy 2020", and the three themes of "smart factory", "smart production" and "smart logistics" were born. Intelligent logistics" three themes came into being. With the arrival of Industry 4.0 era. The concept of intelligent packaging in the domestic market leapfrogged, with technological change, spreading to all packaging equipment, including wrap-around packaging machine.

Wrapping packaging machine with stretch film as the packaging material, applied to pallet packaging, using the winding method to pack a variety of regular or irregular goods, using the retraction and self-adhesive stretch film to bind the goods and pallets into a whole, to play a fixed role, the goods play a dust, moisture, anti-breakage role, especially suitable for cartons, bottles or large items of packaging, transport, or storage.

At present, the level of the domestic winding packaging machine industry has made great progress than before, but the degree of intelligence and technology has not yet reached the level of developed countries, compared with the United States and Japan, the domestic winding packaging machine in the control technology and product reliability gap is obvious.

In order to better implement lean management, improve product operation skills and expand working ideas, on April 25, 2023, Shandong Liyang Intelligent Equipment Co., Ltd. organized a training and learning session for employees to go to the production workshop.

The main content of this study included familiarity with equipment parameters and configuration and mastery of the entire operation process of the equipment. 25 morning, under the leadership of General Manager Mr. Shi, a systematic visit to the small cylinder paper machine P500 and online winding packaging machine was conducted, corresponding to the learning of winding packaging machine operation skills and on-site management. During the whole learning process, everyone studied seriously and asked for advice humbly, showing good spirit.

Small cylinder paper machine P500 winding packaging machine is mainly suitable for cylindrical objects, the size of the goods in the length * width (200-500) mm * (200-800) mm, the weight of 50-60kg, especially for small cylindrical goods closed package, such as: non-woven fabrics, coils, rubber products and their finished products packaging, etc., conducive to the storage of goods, transportation, dust and moisture, etc.. The cylinder machine P500 can choose the size of the film according to the size of the goods, 300mm or 500mm. to fix the goods, both sides of the cylinder machine can be equipped with clamps with axle rollers, which rotate with it. The film frame is fixed, but can be adjusted manually according to the height of the goods, by removing the film frame and adjusting the height manually. The equipment is light, handy, easy to operate and extremely efficient in packing.

The online winding packaging machine adopts integrated design and is connected to the assembly line. The palletizing robot will palletize the goods and give the conveying signal when the palletizing is finished, the online winding packaging machine will display the permission to feed the goods after receiving the signal, and then the goods will be conveyed. After the winding is finished, the automatic film breaking device will automatically cut off the film, and then the electric soldering iron will weld the film flatly on the goods, which is flat and beautiful. After the wrapping is finished, the conveyor signal will be given to transport the goods out. Meet more high-end enterprise assembly line, a collection of automatic laminating machine and in-line packaging machine functions, not only the advantages of the two devices in one, and more smooth operation, more perfect function, high efficiency, simple installation, easy maintenance, operation occupies less space.

Through this training and learning, we benefited a lot. We have not only improved the staff's cognitive ability and operational ability of the products, but also broadened the ideas of on-site lean management, and received a lot of inspiration and learned new methods. We will build on our strengths and make up for our weaknesses and make continuous improvements, so as to improve our work efficiency, enhance the overall image of the company and promote the stable, healthy and sustainable development of the enterprise!
