Description

[Technical Field]

[0001] The present invention relates to a cleaning device. [Background technology]

[0002] During transport of a web of a film product or the like, foreign matter adhering to the web is removed. The removal of foreign matter is carried out, for example, by bringing an adhesive cleaning roll into contact with the web. An adhesive rubber roll or a roll equipped with adhesive tape is used as the cleaning roll.

[0003] As the amount of foreign matter adhering to the cleaning roll increases, the cleaning roll's ability to remove foreign matter decreases, and there is also the possibility that foreign matter adhering to the cleaning roll may be retransferred to the web or may fall off the cleaning roll, causing dents on the web. Therefore, to maintain sufficient adhesive strength of the cleaning roll, it is necessary to periodically clean the surface of the cleaning roll with a dedicated cleaning solution or an organic solvent such as isopropyl alcohol (IPA), or to replace the adhesive tape.

[Figure 4] FIG. 10 is a plan view showing a schematic configuration of a cleaning device according to a modified example. DETAILED DESCRIPTION OF THE INVENTION

[0010] (Embodiment) FIG. 1 is a side view showing a schematic configuration of a cleaning device according to an embodiment, and FIG. 2 is a plan view showing a schematic configuration of a cleaning device according to an embodiment.

[0011] The cleaning device 100 is a device for cleaning the cleaning roll 1, and is equipped with a cleaning liquid application section 11, a foreign matter removal cleaning section 12, a foreign matter removal section 13, a cleaning liquid removal section 14, and a cleaning liquid absorption section 15, arranged in this order along the rotation direction of the cleaning roll 1. The rotation directions of the cleaning roll 1, the foreign matter removal cleaning section 12, and the cleaning liquid removal section 14 are indicated by arrows in the figure. The transport direction of the web 2 is the direction of the white arrow in Figure 1. In Figure 2, the cleaning liquid is indicated by a dot pattern.

[0012] The cleaning roll 1 is an adhesive roll that rotates as the web 2 is transported and comes into contact with the web 2 to remove foreign matter 3 adhering to the web 2. The cleaning roll 1 is, for example, a silicone-based, urethane-based, or butyl-based rubber roll. The web 2 is, for example, a film or glass-based product, but is not limited to these as long as the cleaning roll 1 can remove foreign matter.

[0013] The cleaning liquid application unit 11 applies cleaning liquid onto the cleaning roll 1. The cleaning liquid application unit 11 is equipped with a nozzle with a slit for discharging the cleaning liquid, and discharges the cleaning liquid uniformly across the width of the cleaning roll 1. Because the cleaning roll 1 rotates at a constant speed as the web 2 is transported, the cleaning liquid is applied uniformly to a predetermined area on the surface of the cleaning roll 1. The cleaning liquid contains one or more of paraffinic hydrocarbons, propyl alcohol, fluorinated hydrocarbons, methanol, ethanol, and isopropyl alcohol.

[0014] The foreign matter removal cleaning unit 12 includes a cleaning roll 12a, which rotates to brush and clean the cleaning roll 1, removing foreign matter 3 adhering to the cleaning roll 1. The cleaning roll 12a is provided across the width of the cleaning roll 1 so that the entire surface of the cleaning roll 1 can be cleaned. The cleaning roll 12a may be a fixed roll fixed to the cleaning roll 1, or a drive roll movable relative to the cleaning roll 1 via a drive mechanism. The cleaning roll 12a is made of, for example, a polyvinyl alcohol-based resin. The surface of the cleaning roll 12a has a straight shape, an embossed shape, a brush shape, or a combination of these shapes. Multiple cleaning rolls 12a may be provided as shown in FIG. 1, or a single cleaning roll may be provided. Note that the cleaning roll 12a preferably rotates in the opposite direction to the cleaning roll 1, in which case a higher cleaning effect can be achieved.

[0015] The foreign matter removal unit 13 includes a nozzle 13a and a filter 13b. The nozzle 13a has a suction port extending across the width of the cleaning roll 1 and sucks in the cleaning liquid used for cleaning by the foreign matter removal cleaning unit 12 on the cleaning roll 1. The suction port is, for example, a slit extending across the width of the cleaning roll 1. The cleaning liquid sucked by the nozzle 13a is filtered by passing through the filter 13b, removing foreign matter. The filter 13b is a single-layer or multi-layer filter, and a depth-type filter or a pleated-type filter can be used depending on the type of foreign matter. The filter 13b can be made of any material as long as it is resistant to the cleaning liquid. For example, a fluororesin such as Teflon (registered trademark) or a metal can be used. The cleaning liquid is sucked through the nozzle 13a using a pump (not shown) or the like, filtered through the filter 13b, and then supplied again to the cleaning liquid application unit 11, where it is applied onto the cleaning roll 1. The number of filters 13b may be one or more, and it is preferable to provide the filter 13b and reuse the cleaning solution in terms of environmental impact and operating costs. However, if the cleaning solution is to be discarded, the filter 13b may be omitted.

[0016] The cleaning liquid removal unit 14 is a sponge roll with liquid absorption properties that is provided across the width of the cleaning roll 1. By rotating while pressed against the cleaning roll 1, it removes any cleaning liquid remaining on the cleaning roll 1 that the foreign matter removal unit 13 was unable to suck up. The cleaning liquid removal unit 14 is made of, for example, any of polyurethane-based resin, olefin-based resin, and polyvinyl alcohol-based resin. The cleaning liquid removal unit 14 may be a fixed roll fixed to the cleaning roll 1, or a driven roll that can move relative to the cleaning roll 1 via a drive mechanism. There may be one cleaning liquid removal unit 14, or multiple cleaning liquid removal units 14 may be provided. Note that the sponge roll of the cleaning liquid removal unit 14 preferably rotates in the opposite direction to the cleaning roll 1, in which case a higher liquid absorption effect is obtained.

[0017] The cleaning liquid suction unit 15 is provided so as to be pressed against the cleaning liquid removal unit 14, and absorbs the cleaning liquid contained in the sponge roll of the cleaning liquid removal unit 14. The cleaning liquid suction unit 15 is equipped with a nozzle having a suction port across the width of the cleaning liquid removal unit 14, and a suction mechanism such as a pump (not shown). The suction port is, for example, a slit extending across the width of the cleaning liquid removal unit 14. The cleaning liquid sucked by the cleaning liquid suction unit 15 may be discharged from the system of the cleaning device 100, or may be supplied again to the cleaning liquid application unit 11 and applied onto the cleaning roll 1 from the cleaning liquid application unit 11.

[0018] The cleaning device 100 may be provided with a cover 16 that covers the cleaning liquid application unit 11, the foreign matter removal cleaning unit 12, the foreign matter removal unit 13, the cleaning liquid removal unit 14, and the cleaning liquid suction unit 15. The provision of the cover 16 can prevent the cleaning liquid and foreign matter 3 from scattering onto surrounding equipment. The cover 16 can be made of a metal such as stainless steel or aluminum.

[0019] As described above, the cleaning device 100 according to this embodiment includes the cleaning liquid application unit 11 that applies cleaning liquid to the cleaning roll 1, the foreign matter removal cleaning unit 12 that uses cleaning liquid to clean the cleaning roll 1 and remove foreign matter adhering to the cleaning roll 1, the foreign matter removal unit 13 that sucks cleaning liquid and removes foreign matter from the sucked cleaning liquid, the cleaning liquid removal unit 14 that removes cleaning liquid remaining on the cleaning roll, and the cleaning liquid suction unit 15 that absorbs the cleaning liquid removed by the cleaning liquid removal unit 14. Therefore, cleaning of the cleaning roll 1 with cleaning liquid can be performed inline, eliminating the need to stop the manufacturing process for cleaning the cleaning roll 1. Furthermore, the number of maintenance tasks performed by workers other than those requiring replacement of the cleaning roll 1 due to deterioration of the cleaning roll 1 over time or the occurrence of scratches can be reduced, thereby reducing the burden on workers and the amount of work time required.

[0020] (Variation) Next, a modified example will be described. Figures 3 and 4 are plan views showing a schematic configuration of a cleaning device according to a modified example. In Figures 3 and 4, the cleaning liquid is shown in a dot pattern.

[0021] When foreign matter adheres to the cleaning roll 1 locally, the cleaning liquid application unit 11, foreign matter removal cleaning unit 12, and foreign matter removal unit 13 may be provided partially across the width of the cleaning roll 1, as in the cleaning device 200 in FIG. 3 . That is, the width of the discharge port of the cleaning liquid application unit 11, the location of the cleaning liquid discharge, and the width and position of the foreign matter removal cleaning unit 12 can be adjusted appropriately depending on the location of the foreign matter adhered to the cleaning roll 1. Furthermore, the width and location of the suction port of the foreign matter removal unit 13 can be adjusted appropriately depending on the area and location of the cleaning liquid applied to the cleaning roll 1. However, to prevent the cleaning liquid from remaining on the cleaning roll 1 and reducing its adhesive strength, it is desirable to provide the cleaning liquid removal unit 14 across the width of the cleaning roll 1. The cleaning liquid application unit 11, foreign matter removal cleaning unit 12, and foreign matter removal unit 13 may be moved appropriately depending on the location of the foreign matter adhered to the cleaning roll 1.

[0022] In this way, it is possible to reduce the manufacturing costs of the cleaning liquid and the cleaning device by selectively cleaning the cleaning roll 1 in the width direction. In Fig. 3, three foreign matter removal cleaning units 12 are arranged in the rotation direction of the cleaning roll 1, but the number and arrangement can be appropriately determined depending on the level of foreign matter on the cleaning roll 1 and the locations where foreign matter is likely to occur, and for example, multiple units may be arranged in the width direction of the cleaning roll 1.

[0023] When the foreign matter adhering to the cleaning roll 1 can be removed by the cleaning liquid alone, the foreign matter removal cleaning section 12 may be omitted, as in the cleaning device 300 shown in FIG. [Industrial Applicability]

[0024] The cleaning device according to the present invention can be used as a cleaning device for cleaning a cleaning roll. [Explanation of symbols]
