Description

[Detailed Description of the Invention] The present invention relates to a dust removal roll, and more particularly to a dust removal roll configured to reliably peel off adhesive paper coated with an adhesive layer by layer.

A strip of adhesive paper coated with an adhesive on the front side and a release agent on the back side is rolled around a core material, and is rotatably attached to a support via the core material, allowing it to be used for clothing, etc. 2. Description of the Related Art A dust removal roll for removing dust adhering to carpets and the like is known.

If this type of dust removal roll is used for a predetermined period of time, dust will adhere to the adhesive layer and the adhesive will lose its adhesive strength, so it is necessary to peel and remove the adhesive paper layer by layer. For this reason, in the past, a part of the adhesive paper was perforated along the axial direction, or a cut was made that reached the outer circumferential surface of the core material, and one end of the paper was not coated with adhesive. A dust removal roll has been proposed in which the adhesive paper is peeled off layer by layer.

However, even if such a structure is adopted, the adhesive paper is extremely thin, so even if you try to peel it off one by one from the part where no adhesive is applied, the end surface of the perforation or cut formed in the adhesive paper will not be on the bottom. Since it adheres closely to the adhesive paper, it is difficult to touch the fingers even if you try to peel it off one by one from the top layer, so it is difficult to peel it off.On the other hand, it is difficult to remove the adhesive paper from the perforation or the part other than the cut. It had the disadvantage of being crowded. Additionally, products that simply have perforations or notches have the disadvantage that when fiber waste adheres beyond the perforations or notches, it becomes difficult to peel off the adhesive paper at these areas. Ta.

The present invention was devised to eliminate the above-mentioned conventional drawbacks, and its purpose is to provide a dust removal roll configured to reliably peel off adhesive paper one by one from the upper layer. There is.

Hereinafter, details of the present invention will be explained based on embodiments shown in the drawings.

In the figure, the dust removal roll, the entirety of which is designated by the reference numeral 1, includes a core material 2 made of cardboard or the like, and a core material 2 made of cardboard or the like.
The adhesive paper 3 is wound into a roll on the surface of the adhesive paper 3. A slit-shaped cutout 3a is formed in the adhesive paper 3 wound in multiple layers along the axial direction from the top layer to the surface of the core material 2 over a predetermined width. In addition, the adhesive paper 3 has an adhesive 4 applied to its front side and a release agent applied to its back side, but as shown in FIGS. A portion 3b to which no release agent is applied is formed in the circumferential direction over a predetermined width. At one end of the cutout 3a on the side of the part 3b to which the release agent is not applied, there is a substantially triangular notch 5 that is continuous with the cutout 3a.
is formed including the adhesive paper 3 and the core material 2.

This notch 5 has a special shape.
That is, as is clear from FIGS. 1 and 2, the notch 5 extends outward from the inside of the edge of the part 3b of the dust removal roll 1 on which the adhesive is not coated with a release agent, and It extends from the top layer of the adhesive paper 3 to the core material 2 with an inclined surface that widens toward the center of the roll, and has an open edge at the end of the core material 2, and has a mountain-like shape with an apex in the axial direction. Notched. The inclined surface is inclined to widen toward the axial direction and toward the center.

Therefore, when you insert your fingertip into the notch 5 and try to peel off the top layer of adhesive paper 3 with your fingertip, the adhesive paper 3 is more protruding toward the upper layer, so it is easy to get caught on your fingertip.
It is possible to reliably pick up and peel off the adhesive paper one by one.

The dust removal roll 1 constructed as described above is attached to the support 6 as shown in FIGS. 3 to 5. The support 6 has a hollow grip 7 which is curved upward and has a U-shaped cross section, and a support shaft 8 continuous to the tip thereof.
is rotatably supported.

As shown in FIG. 4, the rotating frame 9 has support plates 9b that protrude radially outward from a bearing portion 9a at the center in the axial direction, and the grips 7 of each support plate 9b
As shown in Fig. 5, there is an arm 9c on the opposite tip side.
A tapered portion 9d is formed on the upper surface of the tip of each arm 9c, and the tapered portion 9d becomes lower toward the tip, and each arm 9c is formed so as to slightly widen outward toward the tip. ing. Arms 9e are also formed on the rear end side of the support plate 9b on the side of the grip 7, each extending rearward. Each of these arms 9c is also formed in a state in which it slightly expands outward as it reaches its tip, and a claw 9f is provided outwardly protruding from the tip. That is, the rotating frame 9 is formed such that the outer edge portion of the central bearing portion 9a is lower and the outer edges of the arms 9c and 9e are higher.

In addition, a through hole 9 is provided in the bearing portion 9a at the center of the rotating frame 9.
g is formed, and a small diameter portion 8a formed at the tip of the support shaft 8 with one step smaller diameter is rotatably fitted into the through hole 9g. By fitting the stopper 10 on the outside of the support plate 9b of the rotating frame 9, the rotating frame 9
is supported so as not to separate from the support shaft 8.

Since the rotating frame 9 has the above structure,
Grip 7 the notch 5 side of the dust removal roll 1.
When fitted to the rotating frame 9 toward the side, the arms 9c, 9
When e moves inward, it is elastically deformed and fitted into the core material 2, and the end edge of the core material 2 is stopped by being locked by the claw 9f at the tip of the arm 9e.

In this state, the rotating frame 9 is tightly fitted inside the core material 2 due to the elasticity of the arms 9c and 9e, and the arms 9c and 9e of the rotating frame 9 are pressed against the inner peripheral surface of the core material 2.
No relative rotation occurs between the dust removal roll 1 and the rotary frame 9, and the dust removal roll 1 can rotate around the small diameter portion 8a of the support shaft 8 integrally with the rotation frame 9.

FIG. 6 shows another embodiment of the dust removal roll according to the present invention, in which the same parts as in the previous embodiment are given the same reference numerals. On both end faces of this dust removal roll 1, portions 3b, 3b to which no adhesive is applied are formed with a predetermined width over the entire circumference. In portions 3b, 3b to which no adhesive is applied at both ends of the cutout 3a, approximately triangular notches 5, 5 are formed to widen toward the outer end. A side surface 5a of the notch 5 is formed as a vertical wall in a direction transverse to the inside of the dust removal roll 1. That is, the side surface 5a does not exist within the plane that includes the center of the dust removal roll, and the opposing cut ends 5b,
5b comrades are parallel.

As is clear from the above description, according to the present invention, an incision of a predetermined width is provided along the axial direction in a part of the adhesive paper rolled into a roll around the core material, and one end side of the dust removal roll or A part where no adhesive is applied is formed around the entire circumference on both end sides, and a part where no adhesive is applied continues from the edge inward in the axial direction. Because it has a structure with a notch that forms an inclined surface, you can insert your fingertips into this notch, making it easy to touch the corners of the adhesive paper, making it possible to reliably peel off the adhesive paper one by one. This has an excellent effect.
