Description

Handling device for strip coils and operating method of the handling device Technical Field

[0001] This disclosure generally relates to the technical field of automatically handling and supplying strip coils for material handling machinery. More specifically, this disclosure relates to a strip coil handling device and a method of operating the strip coil handling device. Background Technology

[0002] Many products are made from long, thin sheets of raw material, which is typically stored and transported in the form of strips or rolls. Continuous strips or rolls of thin, flexible materials are often supplied in stored strip rolls; examples of these materials include plastic films, metal foils, tissue paper or other paper, nonwoven fabrics, and cotton fabrics.

[0003] During the manufacture of paper products such as diapers, newspapers, or magazines, very large storage rolls of raw materials are transported to processing machinery to supply the raw materials, from which the diapers or paper products are made. To accommodate mechanized mass production and improve efficiency, these rolls are often bulky and heavy. After being transported to processing machinery, the stored rolls are installed and then subjected to subsequent processing, such as cutting, folding, or printing machinery for producing diapers, sanitary napkins, newspapers, or magazines.

[0004] The material handling machine receives strip coils, in which elongated sheet-like material is wound around a tubular core. It then unwinds the coils and positions the free ends for subsequent processing. Currently, the handling, loading, and installation of the free ends of the strip coils are manual processes. The operator must retrieve the strip coils from their storage location, load them onto the machine, and install the free ends in the appropriate positions. When the material on the machine is depleted, the operator must remove the coils, load them back onto the machine, and manually thread the free ends to secure them. This manual loading method is physically demanding and reduces the overall efficiency of the material handling machine's production process.

[0005] Therefore, it is necessary to eliminate the manual labor required for handling and loading strip rolls onto material-using machinery, threading the free ends of the strip rolls, and installing them in suitable positions on the machinery to supply the equipment for manufacturing products such as diapers. Furthermore, it is necessary to reduce the floor space required for raw material handling, loading, and installation. Additionally, it is necessary to achieve a strip roll material supply solution that is nearly "unattended." Therefore, it would be advantageous to simultaneously address the issues of small footprint, reduced labor intensity, and lower costs. The technical solution disclosed herein solves these problems.
