Abstract

PURPOSE:To enable an adhesive sheet to be placed on a frame without any need of a peeling work by providing an adhesive tape takeup device for winding the adhesive tape rolled at one side of the frame toward the other side thereof. CONSTITUTION:This roll type dust collecting sheet removes dust in such a way that an adhesive layer 2 collects the dust adhering to the footwear or wear of people passing on an adhesive sheet 1 paid out from a rolled sheet 4 via a takeup device 5 and placed on a frame 6. Thus, bacteria adhering to the dust is not carried therewith into a clean room including a sickroom. In this case, the dust collecting sheet is so made that the adhesive tape 1 on the frame 6 is wound by length corresponding to the length thereof with the device 5, when the sheet is contaminated to a certain extent due to the passage of people and carriages, and then, a new section is paid out from the rolled sheet 4 to the frame 6. This process is repeated, and dust can be thereby removed efficiently and accurately. The type of the device 5 may be arbitrary such as manual or electric type, and the adhesive sheet 1 can easily be placed on the frame 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust removing sheet for a clean room such as a hospital, a food-related factory, a semiconductor manufacturing factory.

[0002]

2. Description of the Related Art It is necessary to clean rooms and floors in hospitals from the viewpoint of preventing nosocomial infections, in food factories from the viewpoint of public health, and in semiconductor factories to improve product yield. ,
Especially in hospitals, where necessary, clean room facilities are installed, but dust that holds bacteria is drawn from the doorway of the room from stretchers for patients, various instruments, nurses and other general employees. Always brought in. In particular, the hospitalized room for patients with infectious diseases needs to be sterile.

Therefore, for the purpose of removing dust adhering to the footwear of a person who enters the room when entering the room, an adhesive is applied to the film, mainly on the floor of the entrance / exit, and an adhesive sheet having many layers is placed on the film. Sterilized by passing through. The adhesive sheet laminated with the film coated with this adhesive will become dirty and lose its effect after half a day to one day of use, so it is necessary to peel off one of the uppermost layers to expose a new adhesive surface and keep the surface clean at all times. There is.

Usually, several to several tens of the pressure-sensitive adhesive sheets are stored in the frame, and the surface is peeled before the dirt and dust removing effect disappears, but it is unsanitary because it is manually performed and the size is 1 to 2 m ×. This is a troublesome work because it can take up to 1 to 3 and requires peeling force and the peeling frequency is high.

[0005]

DISCLOSURE OF THE INVENTION The present invention provides a dust removing sheet which solves the conventional problems of the pressure sensitive adhesive sheet and allows the pressure sensitive adhesive sheet to be mounted on the frame easily and surely by eliminating the peeling work. is there.

[0006]

According to the present invention, a pressure-sensitive adhesive sheet winding device is provided in which a pressure-sensitive adhesive sheet rolled on one side of a frame is rolled on the other side of the frame, and the pressure-sensitive adhesive sheet is rolled onto the frame by a roll-rolled pressure-sensitive adhesive sheet. It is on a roll-type dust removal sheet that I tried to extend.

The present invention will be described below with reference to the drawings.
FIG. 1 shows a perspective view of one embodiment of the present invention, in which reference numeral 1 is an adhesive sheet unrolled on a frame 6,
The pressure-sensitive adhesive sheet 1 is provided in a rolled state 4 on one side of the frame 6, and is wound by a certain length by a winding device 5 provided on the other side of the frame 6.

FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG. 3 is a sectional view taken along line BB of FIG. Since the frame 6 has a slanted edge as shown in FIGS. 2 and 3, it is easy for a person or a dolly carrying an article to pass therethrough. The frame 6 is made of rubber, synthetic rubber, or synthetic resin, and has a size of about 1 to 2 m × 1 to 3 m, although it depends on the purpose of use and the place of use.

The frame 6 may be provided with a sandwiching portion 7 at both ends on which the adhesive sheet 1 is placed. Adhesive sheet 1
As shown in the figure, a non-adhesive portion 3 to which the adhesive 2 is not applied is provided at both ends in the length direction of the film or sheet constituting the sheet. The non-adhesive portion 3 is inserted into the sandwiching portion 7 of the frame 6 so that the dust removing sheet does not get entangled with a person's foot passing through or a wheel of a dolly on which equipment is loaded when in use. Further, since both ends are sandwiched, it does not float on the frame 6. Instead of the sandwiching portions 7 at both ends of the frame 6, a plurality of rolls may be installed on the sandwiching portions and the adhesive sheet 1 may be passed under the rolls to prevent the adhesive sheet from floating.

The roll-type dust-removing sheet of the present invention is a person's footwear or equipment, such as a strike, that passes over the pressure-sensitive adhesive sheet 1 that is unwound from the roll-wound pressure-sensitive adhesive sheet 4 by the winding device 5 and placed on the frame 6. Dust adhering to the dolly truck or the like is attached to the adhesive layer 2 to be removed, and bacteria adhering to the dust are not brought into the clean room such as a patient room together with the dust.

In the dust removing sheet of the present invention, when a person, a truck or the like passes through to some extent and the dust removing sheet becomes dirty, the winding device 5 winds the adhesive sheet 1 on the frame for the length of the frame 6 and rolls a new surface. Then, the adhesive sheet 4 is unwound onto the frame 6. By repeating this, dust can be removed efficiently and surely. As the winding device, any device such as a manual device or an electric device can be used, and the adhesive sheet can be easily placed on the frame 6.

In the figure, reference numeral 8 is a stand for the rolled adhesive sheet 4, and 9 is a used adhesive sheet. When the rolled adhesive sheet 4 is used, it is removed and incinerated as appropriate.

[0013]

Since the present invention is constructed as described above, it is installed at the entrance of a hospital room, the entrance of an operating room, the entrance of a clean room of a semiconductor manufacturing factory, and the winding device is operated when the surface is dirty. Then, a new adhesive surface can be easily put out, and the people who enter the room and the articles can be cleaned. Further, since the rolled up adhesive sheet can be disposed of as it is, it is more hygienic and easier to handle than conventional ones.
