Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cleaning tool.
[0002]
[Prior art]
The cleaning tool described in Japanese Utility Model Publication No. 1-17246 is used by taking out a roll-shaped adhesive sheet loaded inside a drum from the sheet outlet of the drum and winding it around the outer periphery of the drum.
[0003]
[Problems to be solved by the invention]
(1) In order to prevent the tip of the adhesive sheet wound around the drum from sticking to the floor surface and peeling off from the outer periphery of the drum, the tip is fixed to the shaft piece provided on the drum. The structure of the cleaning tool is complicated and difficult to handle.
[0004]
(2) The end of the adhesive sheet wound around the drum sticks to the floor surface, and a new adhesive sheet is pulled out from the roll inside the drum to prevent the adhesive sheet from sagging on the drum. Therefore, the roll winding lock device is provided, the structure of the cleaning tool is complicated, and the use is complicated.
[0005]
(3) Since no means for cutting the tip of the adhesive sheet taken out from the drum is provided, it is necessary to prepare a knife or the like separately, which is complicated.
[0006]
An object of the present invention is to enable easy cutting of an adhesive sheet taken out from a drum and to easily hold the adhesive sheet around the drum.
[0007]
[Means for Solving the Problems]
The present invention is a cleaning in which a roll-shaped adhesive sheet loaded inside a drum is taken out from a sheet outlet provided along a part of the outer periphery of the drum along the axial direction of the drum and wound around the outer periphery of the drum. The front end portion and the end portion of the new adhesive sheet for approximately one turn drawn out from the inside of the drum are in contact with both side portions sandwiching the sheet outlet in the circumferential direction of the drum on the outer peripheral surface of the drum. parts pressing on the drum from the outside of the novel pressure-sensitive adhesive sheet, and so that the end portion of the novel pressure-sensitive adhesive sheet followed the used adhesive sheet of the sheet retainer for cutting and separating the distal end portion of the novel pressure-sensitive adhesive sheet becomes provided on the drum It is a thing.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the cleaning tool 10 includes a support member 13 connected to an operation member 11 via a universal joint 12, a rotating shaft 14 provided on the support member 13, and an unwinding provided on an end plate 16 of a drum 15. The shaft 17 is rotatably supported on the rotating shaft 14.
[0009]
The cleaning tool 10 can load the roll 30 of the adhesive sheet 31 inside the drum 15 by opening and closing the end plate 16 of the drum 15 or the like. The inner diameter portion of the roll 30 is fitted to the unwinding shaft 17 of the drum 15 in a press-contact state, and the adhesive sheet 31 can be pulled out in a tension-applying state that resists the frictional force with the unwinding shaft 17. The roll 30 is wound with the pressure-sensitive adhesive surface of the pressure-sensitive adhesive sheet 31 inside, and does not involve release paper.
[0010]
As shown in FIG. 2, the cleaning tool 10 has a part of the outer periphery of the drum 15 as a sheet take-out port 18, a sheet take-out port 18 of the drum 15 and both outer surface portions thereof as recesses 19, and the drum 15 except for the recess 19. The outer periphery is covered with a cushion material 20. The cleaning tool 10 supports a sheet presser 21 on one end side of the sheet take-out port 18 of the drum 15 so as to be swingable, and allows the sheet presser 21 to be stored in the recess 19. The sheet presser 21 stored in the recess 19 holds the locking part 21A with the locking part 15A of the drum 15 and holds the sheet take-out port 18 of the drum 15 on both sides of the sheet presser 21. The outer surface of the sheet presser 21 is made lower than the outer surface of the cushion material 20. One edge of the sheet presser 21 is a sheet cutting portion 22.
[0011]
The adhesive sheet 31 inside the drum 15 is taken out from the sheet take-out port 18 of the drum 15, is reversed at the sheet take-out port 18, and the pressure-sensitive adhesive surface thereof is directed outward. The tip 32 of the pressure-sensitive adhesive sheet 31 wound around the drum 15 is overlapped and adhered to the end portion 33 of the pressure-sensitive adhesive sheet 31 immediately after being taken out from the sheet outlet 18 within the range of the above-described recess 19. Is done. The overlapping portion between the leading end portion 32 and the terminal end portion 33 of the adhesive sheet 31 is pressed and held by the sheet presser 21 from the outside to the concave portion 19 of the drum 15 (FIG. 3A). The pressure-sensitive adhesive sheet 31 that makes a round of the drum 15 rotates around the rotation shaft 14 together with the drum 15 and rolls on the surface to be cleaned, so that dust foreign matter on the surface to be cleaned can be captured and adhered.
[0012]
When the adhesive force of the used adhesive sheet 31A for one circumference of the outer periphery of the drum 15 is reduced by the course of use, the sheet presser 21 is released from the recess 19, and the leading end portion 32 of the used adhesive sheet 31A is grasped and followed. The new adhesive sheet 31B is pulled out from the drum 15 for one turn (FIG. 3B). The overlapping portion of the leading end portion 32 and the terminal end portion 33 of the new adhesive sheet 31B is pressed against the concave portion 19 of the drum 15 by the sheet presser 21 and held, and the terminal end portion 33 of the used adhesive sheet 31A is held by the sheet cutting portion 22 of the sheet presser 21. Is cut and separated from the tip 32 of the new pressure-sensitive adhesive sheet 31B (FIGS. 3C and 3D). The new adhesive sheet 31B can be smoothly wound around the drum 15 by being pulled out from the drum 15 through the used adhesive sheet 31A.
[0013]
According to this embodiment, there are the following operations.
(Operation corresponding to claim 1)
(1) Since the sheet presser 21 for cutting the adhesive sheet 31 is provided on the drum 15, the adhesive sheet 31 can be easily cut.
[0014]
(2) The front end portion 32 of the adhesive sheet 31 is pressed by the drum 15 by the sheet presser 21 and is simply held. It can prevent that the front-end | tip part 32 of the adhesive sheet 31 wound around the drum 15 sticks on a floor surface, and peels from the outer periphery of the drum 15. FIG.
[0015]
(Operation corresponding to claim 2)
(3) The end portion 33 of the adhesive sheet 31 is also pressed by the drum 15 by the sheet presser 21 and is simply held. The end portion 33 of the adhesive sheet 31 wound around the drum 15 is stuck to the floor surface and prevented from being pulled out from the roll 30 inside the drum 15, and the sagging of the adhesive sheet 31 occurs on the drum 15. Can be prevented.
[0016]
Further, since the sheet presser 21 is disposed at the sheet take-out port 18, the length of the overlapping portion between the leading end portion 32 and the terminal end portion 33 of the adhesive sheet 31 can be shortened. Further, when the sheet presser 21 is released from the concave portion 19, the tip end portion 32 of the used pressure-sensitive adhesive sheet 31 </ b> A is attached to the sheet presser 21 and peeled off from the overlapping portion with the terminal end portion 33. The drawer can be started immediately.
[0017]
【The invention's effect】
As described above, according to the present invention, the pressure-sensitive adhesive sheet taken out from the drum can be easily cut, and the pressure-sensitive adhesive sheet can be easily held around the drum.
