[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a dust-collecting roll that uses an adhesive.

[0002]

[Prior art]

 A dust-collecting roll made by winding a long tape with an adhesive on one side and a release agent on the other side is wrapped around a winding shaft to remove dust, lint, hair, etc. from clothing, carpet, floor, etc. It is widely used to remove dust that cannot be removed by vacuum cleaners.

This type of dust-absorption roll has a second dust-absorption capability as the roll rotates on the target surface and adsorbs dust. Therefore, it is necessary to pull out the tape to expose the fresh surface after a certain amount of use. However, in that case, it is difficult to understand the boundary with the fresh surface, and it is also difficult to exactly break the old surface. As shown in Figures 10 and 11, the rolls 1'and 1 "have fine notches 8 at the ends, but it is difficult to peel them off, and the tears are ugly. In addition, there are also those with perforations 7 along the axial direction as shown in Fig. 11, but in each case a large force is required for the first peeling, so there is often the drawback of causing irregular tears. It is also unclean because it is necessary to grip the contaminated roll surface during peeling.

[0004]

[Problems to be solved by the device]

 In view of the above situation, an object of the present invention is to solve the above-mentioned problems in a dust-collecting roll and to provide a practical means for easily and reliably removing a used old surface without waste. To do.

[0005]

[Means for Solving the Problems]

 (1) Outline In order to solve the above problems, the present invention is characterized in that a roll of adhesive paper wound around a winding shaft has a score line along an inclined surface with respect to the axial center surface of the winding shaft. The main point is dust collection rolls. The various elements that compose the invention will be described below item by item.

(2) Roll of Adhesive Paper In the present invention, “adhesive paper” means a base polymer, a viscosity imparting agent, and a plasticizer on the opposite side of a thin cloth such as paper or non-woven fabric having one surface subjected to release processing. A tape-shaped thin piece (adhesive tape) having a pressure-sensitive adhesive layer formed of, for example, is wound around a hollow core rod (winding shaft) in a roll shape with the adhesive layer facing upward. Natural rubber or synthetic isoprene rubber and polyacrylate are often used as the base polymer of the adhesive. In the commercially available dust collecting roller shown in FIGS. 10 and 11, the support shaft 6 which is an extension of the handle 5 is inserted into the inside of the winding shaft 4 so that it can rotate freely.

(3) Notch Line The notch line which is a characteristic configuration of the present invention is the winding axis of the roll, in other words, the axis of the hollow roll along the plane inclined with respect to the virtual axis plane of the roll. It is provided toward the direction. With reference to FIGS. 1 and 2, this score line is preferably provided so as to return to the initial state when the roll makes one revolution. That is, as shown in FIG. 2, the score lines 3, 3, ... In the adhesive tape 2 constituting the roll 1 are linearly inclined with respect to the longitudinal direction of the tape 2 at substantially constant intervals. Will exist.

Assuming that the tape width is a, the height of a rectangular contour in which each score line 3 is a diagonal line is b, the roll radius is r, and the pi is π, the length c of each score line 3 is , A ² + 2π r ² = c ² , the inclination angle θ of the score line 3 with respect to the longitudinal direction of the tape 2 is easily calculated from the formula of a sin θ = ──────── √a ² + 2πr ^2. it can.

However, as the diameter of the roll gradually decreases due to the consumption of the tape, the circumference of the roll 1 gradually decreases. Therefore, if the width a and the inclination angle θ are constant, the height corresponding to one rotation of the roll is high. b, that is, the pitch of the cuts is gradually shortened, but this does not affect practicality.

The cut line 3 may be a continuous or discontinuous straight line shape, or a concave arc or a convex arc shape, but it is a complete cut line at least at the starting end. Is good. In particular, as shown in Fig. 7 to Fig. 9, the zigzag or slanted kerf line 3 "consisting of short linear or chevron-shaped unit cuts or the chevron-shaped kerf line 3 ^'" is used for peeling. It is practically advantageous in that it does not require cutting, and there is no fear of accidentally peeling it down to the fresh roll surface below.Incision can be made with a tool such as a thin rotary grindstone.

[0011]

[Action]

With reference to FIG. 3, the unrolled state of the roll 1 is the state (a). When this is used for the first time, the entire surface (A-side and B-side) within the rectangular contour whose diagonal lines are the cut lines 3 _1, 3 _2, ... Is contaminated. Then, C surface of the downwardly exposed when removing the A side from the score line 3 _1, the use state of the second time (b). And removal of the second time B face and C face was contaminated from use after cutting Looking 3 _2, exposed and D plane and E-plane, on purpose made third-time use ready-shaped ((c)). Thereafter, the new surface F each time to remove the spent surface through one after another score line ₃ 3 ···, G ··) appears, Ru can be used until the tape will be exhausted.

According to the above configuration, since the starting end of each cut line is located at the upper left corner in the figure in an acute angle, it is easy to find the cut lines, and since the cut lines are continuous, the used portion is removed. Is extremely easy, and there is no fear of wasteful peeling. In addition, peeling starts from the narrow beak-shaped end, and there is no excessive adhesive force between the adhesive layer directly underneath, so there is little concern that a new tape will be unnecessarily peeled off. In particular, in the case where the cuts are arranged in rows as shown in Fig. 8, a large force is not required for peeling and the shearing action exerted on the lower fresh surface can be locally reduced, so that useless peeling can be completely prevented. .
