Technical Field

The invention belongs to the technical field of film winding equipment, and particularly relates to an automatic roll-unloading and shaft-loading device and an automatic roll-unloading and shaft-loading method.

Background

After the film is produced, the film needs to be coiled into a coiled material by utilizing coiling equipment. The winding device comprises a winding shaft and winding supports used for supporting two ends of the winding shaft, the winding supports are provided with rotatable plugs, tapered jacks matched with the tapered plugs are arranged at the left end and the right end of the winding shaft respectively, the tapered jacks at the two ends of the winding shaft form movable splicing relations with the plugs on the corresponding sides respectively, and the winding supports are further provided with winding motors driving the plugs to rotate.

Most of the film needs to be applied to the paper core cylinder in the coiling process, the paper core cylinder is sleeved outside the coiling shaft, and the coiling shaft is utilized to drive the paper core cylinder to rotate ceaselessly, so that the film material is coiled around the paper core cylinder ceaselessly; in order to enable the winding shaft to drive the paper core cylinder to rotate, the corresponding winding shaft is generally an air expansion shaft, the winding shaft is expanded in a cylinder cavity of the paper core cylinder during operation, the air expansion shaft is deflated and loosened during coil unloading, and then the air expansion shaft is pulled out from the middle of the paper core cylinder. This winding method is called a core winding method.

However, some other films need to stand for several days immediately after being produced and wound into a roll, and after the physical and chemical properties are stabilized, the film is unwound and unwound again (i.e., unwound), and the film is slit while being unwound. Because the films need to be unwound again after being wound for the first time, the paper core cylinder is not needed in the process of winding for the first time, and the films are directly wound on a metal winding shaft, and the winding mode is called an optical axis winding mode.

When the optical axis winding mode is carried out, the winding shaft on the winding support rotates ceaselessly, so that the film material is reeled up ceaselessly to form a film roll, and after the reeled film material reaches a set length and the film roll reaches a set diameter, the film roll and the winding shaft are required to be unloaded from the winding support, and the process is called as roll unloading. For the winding frame, after the coiled material (together with the winding shaft) is removed from the winding frame, the winding frame needs to be loaded with a new winding shaft for the next winding, and this process is called "upper shaft".

Obviously, the process of unwinding and winding the shaft in the optical axis winding mode is different from the process of unwinding and winding the core in the paper core tube winding mode.
