Automatic unwinding and winding device and automatic unwinding and winding method

Abstract

The invention provides an automatic unwinding and winding device. The automatic unwinding and winding device comprises a left winding shaft support and a right winding shaft support, wherein a clamping assembly is further arranged behind the left winding shaft support, a clamping plate support is further provided with an air nozzle connector and a proximity switch used for sensing the position ofthe winding shaft, the left end of a gas nozzle joint is connected with a two-way electromagnetic valve, a transverse guide rail which transversely extends is arranged on the right side of the clamping assembly, a carrying trolley is installed on the transverse guide rail, the carrying trolley is further provided with a left unwinding swing arm, a right unwinding swing arm, a left longitudinal lifting rail and the right longitudinal lifting rail, a vertical lifting arm can be installed on each longitudinal lifting rail in a sliding mode, and a mechanical clamping hand is installed at the lowerend of each vertical lifting arm; and a supporting arm assembly is further arranged beside the transverse guide rail. The invention further provides an automatic unwinding and winding method. The device has the advantages that the automation degree is high, a vehicle roof panel does not need to be lifted, and the structure is compact.

Description

technical field [0001] The invention belongs to the technical field of film winding, and in particular relates to an automatic unwinding core device and an automatic unwinding core method. Background technique [0002] After the film is produced, it is usually wound up into a coil using a winding device. During the winding process, the position of the winding shaft is called the winding position, and the paper core tube sleeved on its outer periphery is driven by the winding shaft to rotate continuously, so that the film material is continuously rolled onto the paper core tube to form a film roll. The specifications of the paper core tube are standard specifications. When the film roll reaches the set length and the film roll reaches the set diameter, it is necessary to remove the film roll from the winding position and extract the film roll (together with the paper core) from the winding shaft. This process is called " unload". After the unloading is completed, it is nec...

Problems solved by technology

[0004] The traditional coil unloading and core loading processes are mainly carried out manually, with a low degree of automation and high labor intensity

In order to improve the automation of the coil unloading and core loading process, the applicant continued to explore and applied for the CN201611060866.7 invention patent, but there are still many things to be improved in the above patent: 1. Failed to realize automatic deflation, let alone For automatic inflation, it can only be inflated and deflated by workers; 2. The top panel of the carrying trolley carrying the film roll must be able to lift accurately so that the winding shaft can be accurately inserted into the paper core tube when the core is loaded. The panel has a large area and must be driven by four vertical motion mechanisms arranged under the corners of the top panel, and the four vertical motion mechanisms must be synchronized to realize the synchronous rise or fall of the top panel as a whole. Therefore, it is required The vertical movement mechanism is relatively precise, but on the other hand, when the carrying trolley carries the film roll, its load capacity is large, so the vertical movement mechanism is required to be relatively heavy and strong. The production cost of the vertical movement mechanism of the top panel is often high; 3. Not only the carrying trolley is required, but also the core pulling trolley is required, that is, two trolleys are required, and each trolley needs to be equipped with a corresponding track; 4. The degree of automation is still to be determined improve
