Does the packaging process always rely on manual coordination? Online top-covering and wrapping machine helps enterprises achieve unmanned and stable shipments

In the shipment link of manufacturing enterprises, the packaging process has always been an important link affecting the overall logistics efficiency. Especially for industries that require pallet shipment, how to achieve fast, consistent, and high-standard packaging operations while ensuring the stability, moisture-proof and dust-proof of goods has become a key factor affecting the shipment rhythm and customer experience. Although the traditional wrapping method can meet the requirements of film sealing on all sides, the top of the goods often requires manual film covering, which not only increases manpower consumption, but also leads to uneven packaging quality and difficulty in improving shipment efficiency. With the continuous deepening of packaging automation, an "online top covering and wrapping machine" that integrates film covering and wrapping functions has emerged and has been quickly applied in the chemical, building materials, food, logistics, home appliances and other industries, becoming the preferred equipment for improving packaging consistency and reducing labor input.

The online top covering and wrapping machine mainly combines the automatic top covering film system with the wrapping packaging system to complete the linkage operation of top protection and side wrapping of goods. After the equipment recognizes that the pallet is in place through the photoelectric sensor, the top film supply system first accurately cuts and releases the film, and automatically covers the film at the specified position above the goods; then the wrapping system automatically starts, and the film rack performs pre-stretching and wrapping operations on the pallet. The wrapping range can be automatically adjusted according to the product height, and the number of wrapping turns, tension force, and winding speed can be flexibly set on the operation panel. The entire packaging process, from the pallet being put on the line to the completion of the top covering, and then to the end of the whole pallet wrapping, does not require manual intervention throughout the process, effectively realizing the automation, standardization and rhythm of shipping packaging.

In actual applications, a chemical company in Shandong mainly ships products such as bagged putty powder and dry mortar. In the past, manual film covering + semi-automatic wrapping machine was used for pallet packaging. Two employees could only complete 20 pallets per hour, and problems such as inconsistent packaging layers and loose adhesion of the top film occurred frequently, resulting in a high rate of cargo damage during transportation. Since the introduction of the online top-covering and wrapping machine, the equipment has been seamlessly connected to the original palletizing conveyor line to automatically complete the top film sealing and wrapping operations of each pallet. The single-line hourly shipping capacity has been increased to more than 40 pallets, saving 50% of labor, significantly improving the packaging appearance and stability, and reducing the customer complaint rate by more than 70%. The person in charge of the company said that compared with the original multi-process segmented operation, the biggest advantage of the integrated equipment is not only labor saving, but also the uniform film wrapping position and tight top film fit, making the packaging look "more like a product rather than a temporary patchwork".

From the perspective of equipment structure design, the online top-covering and wrapping machine adopts a modular frame design, which is convenient for integrated use with conveying systems, automatic palletizing systems, and code scanning equipment. The film frame part supports the dynamic pre-stretching structure, and the stretching ratio can reach up to 250%, which effectively saves film wrapping consumables; the top film laminating system supports fixed-length cutting, automatic adsorption, and non-offset placement. The top film pasting alignment error can be controlled within ±10mm, which is suitable for pallet goods of various specifications. The operating system generally adopts PLC+touch screen control interface, supports multiple sets of program parameter storage, fault alarm, abnormal recording and other functions, which is convenient for on-site personnel to quickly operate and maintain management.

The emergence of online top-covering and wrapping all-in-one machine not only solves the problems of low efficiency and unstable manual film pasting, but also comprehensively improves the consistency of shipment rhythm and packaging standards through the structural upgrade of packaging operations. It is no longer a simple function superposition of traditional wrapping machines, but an intelligent integrated solution for future packaging factory scenarios. For factories with a large number of full-pallet shipment needs, the investment in such equipment can not only recover costs in a short time, but also fundamentally improve the professionalism, efficiency and customer recognition of enterprises in the delivery link.
