Description

Apparatus and method for manufacturing glass roll Technical Field The present invention relates to an apparatus and a method for manufacturing a glass roll. Background The glass roll is manufactured based on an ultra-thin glass ribbon (for example, a thickness of 200 μm or less). Patent document 1 discloses an example of a method for producing a glass roll from a glass ribbon. In this method, first, an ultra-thin glass ribbon is formed by a down-draw method. Next, the conveyance direction of the formed glass ribbon is switched from the longitudinal direction to the transverse direction. Thereafter, the glass ribbon in transit in the transverse direction will be removed without partial breakage. Finally, the glass ribbon is wound around the winding core in a state of overlapping with the protective sheet in a winding region arranged at the downstream end of the conveyance path of the glass ribbon, and is set as a glass roll. The protective sheet is supplied from a roll of the protective sheet wound up in a roll form before being overlapped with the glass ribbon. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2015-63450 Disclosure of Invention Problems to be solved by the invention When a glass ribbon is wound in the above manner to produce a glass roll, there is a problem that the productivity of the glass roll is lowered due to poor maintainability of production equipment disposed in the winding area. As an example of the manufacturing equipment, a power device coupled to a shaft portion of a winding core to apply torque for rotating the winding core is given. A member for supporting the winding core (hereinafter, referred to as a winding core supporting member), a member for supporting the sheet winding (hereinafter, referred to as a sheet winding supporting member), and the like are disposed in the vicinity of the power device. The core support member is a member for placing the core before winding of the glass ribbon starts and after winding is completed. The roll supporting member is a member for placing the rolls before and after the winding of the glass ribbon is started. In the maintenance work of the power unit, it is necessary to retract all of the winding core, the winding core support member, the sheet roll, and the sheet roll support member from the winding area (the vicinity of the power unit) so as not to be an obstacle to the work. However, no means for collectively retracting all of them is adopted, and the time required for retraction is long, and as a result, the maintainability of the power plant is poor. This causes a decrease in productivity of the glass roll. In view of the above, an object of the present invention is to improve productivity in manufacturing a glass roll. Means for solving the problems The apparatus for producing a glass roll for winding a glass ribbon to obtain a glass roll is characterized by comprising a winding unit that is provided with a winding core support unit that supports a winding core for winding the glass ribbon in a roll shape in a winding region disposed at a downstream end of a conveyance path of the glass ribbon in a state of overlapping a protective sheet, and a sheet roll support unit that supports a sheet roll in which the protective sheet is wound in a roll shape, and a transfer mechanism that transfers the winding unit in unit between the winding region and a retraction region separated from the winding region. The apparatus for producing a glass roll is provided with a winding unit which is provided with a roll core supporting part for supporting a roll core and a roll supporting part for supporting a roll sheet so as to be capable of integrally moving. The winding unit can be transferred between the winding area and the retraction area separated from the winding area by a transfer mechanism for transferring the unit. This can improve the maintainability of the manufacturing equipment (for example, the power plant described above) disposed in the winding area. More specifically, during maintenance work of the manufacturing equipment, the winding cores, the winding core supporting portions, the sheet rolls, and the sheet roll supporting portions can be all retracted from the winding area (the vicinity of the manufacturing equipment) so as not to be an obstacle to the work, and can be retracted at once in unit units. Thus, the time required for the evacuation can be shortened, and the maintainability of the manufacturing facility can be improved. As a result, the productivity of the glass roll can be improved. In the above configuration, the apparatus for producing a glass roll preferably includes a plurality of winding units. In this way, the productivity of the glass roll can be further improved. This is based on the following reason. When a glass roll around which a glass ribbon of a desired length is wound is completed, preparation operations such as the following (1) to (3) are required to s
