Description

The present invention, dust removal roll for removing dust, in particular, relates to the production how suitable dust removal roll for you remove dust adhering to the printed circuit board, further details, leftover dusts, cutting lines In the case of dust accumulation due to the level difference due to spreading in the winding direction of the roll and swelling from the outer surface of the roll in the vertical direction, and when the used outermost part (updated part) is cut off with a cutting line and peeled off with overlap peeling can be effectively prevented, respectively, cutting and peeling of the updated portion is directed to a simple and efficient production how easy dust removal roll.

As a method for removing (dedusting) dust adhering to an object, for example, a method for removing dust adhering to a dirty carpet, floor surface, etc. , a rotating roll made of synthetic rubber can be used for a dirty carpet, floor surface, etc. A method for removing the dust by adhering dust (dust) to the adhesive layer is performed. In this case, if a large amount of dust adheres to the adhesive surface and the adhesiveness is reduced and cannot be removed, the wound part is used to peel off the used part (updated part) and expose the new adhesive surface. Discontinuous cutting lines (perforations) are formed at predetermined intervals in the winding direction of the adhesive tape wound around the core (so that they overlap at substantially the same position when wound on the core). In this case, cutting is performed to peel off the updated portion (see, for example, Patent Document 1).

  However, in the case of the dust removal roll using the adhesive tape in which the discontinuous cutting line (perforation) as described above is formed, the discontinuous cutting line rises along the hole portion, and a step is generated on the surface of the roll. The smooth rotation of the roll is impaired (generation of noise, etc.), and it is difficult to attach dust to the adhesive surface in the vicinity of the portion, and there is a problem that dust is left behind. Also, the longer the part of the cutting line, the easier it is for the part of the cutting line to spread in the winding direction, and the dust gets into the back of the part of the extended cutting line and the dust stays there. was there. In addition to the dust removal roll described above, it is known that the cutting line is formed obliquely, and the cutting line part is abutted and overlapped, but both are easy to cut and peel from the cutting line. However, it was difficult to prevent dust from staying in the gap due to the rise and spread of the cutting line portion.

In particular, since the mounting density of printed circuit boards has increased in recent years and a large problem has occurred due to the adhesion of fine dust, it has been demanded that further complete dust removal be performed. It was not enough. In addition, due to the demand for shortening the replacement time of the dust removal roll, it is required to lengthen the adhesive tape used for the dust removal roll. To cope with this, the thickness of the base material constituting the adhesive tape is reduced. It is requested to do. For this reason, with conventional adhesive tapes using cutting lines consisting of discontinuous lines such as perforations, the base material stretches during winding or peeling, making smooth winding difficult, and the cut surface is There has also been a problem that the irregular shape is formed, and dust remains easily.

The present invention has been made in view of the above-described background art, and in particular, is a method of manufacturing a dust removal roll suitable for removing dust adhering to a printed circuit board. Generation of dust pools due to steps due to spreading in the take-up direction and bulge in the vertical direction from the outer surface of the roll, and overlapping peeling when the used outermost peripheral part (updated part) is cut off at the cutting line and peeled off It is an object of the present invention to provide a simple and efficient manufacturing method of a dust removal roll that can effectively prevent each of the above and the like, and can easily cut and peel the renewal part.

The present invention, in order to achieve the above object, the following production how the dust removal roll is provided.

[ 1 ] An adhesive tape having a predetermined width and having an adhesive surface is wound around a core with the adhesive surface as an outer surface, and an outer surface newly peeled off from the used outermost peripheral surface of the adhesive surface is used. A method for manufacturing a dust removal roll that can be used repeatedly, and a center of the raw adhesive tape that is wider than the adhesive tape, leaving a portion (non-cut portion) at a predetermined distance from each end. The continuous line-shaped cutting line (continuous cutting line) extending in the width direction is overlapped at substantially the same position in a state where the original fabric adhesive tape is wound around the core. The step of forming a plurality of the gaps between the cutting lines sequentially toward the outer peripheral side, winding the original fabric adhesive tape formed with a plurality of the continuous cutting lines around the winding core, Forming the raw material A plurality of continuous cutting lines extending in the width direction from one end to the other end at predetermined intervals in the winding direction. In the state where the adhesive tape is wound around the core and the adhesive tape is wound around the core, the interval between the continuous cutting lines is such that the continuous cutting lines overlap at substantially the same position. The dust removing unit is arranged so as to increase gradually toward the outer peripheral side, and further, the cut portion of the continuous cutting line is configured to be in close contact with the outer surface without rising in the vertical direction and without spreading in the winding direction. Forming a dust roll, and a method for producing a dust removal roll.

[ 2 ] The ratio ( ( D / W ) × 100) of the predetermined distance (D) of the uncut portion in the original fabric adhesive tape to the width (W) of the original fabric adhesive tape is 4 to 8%. The manufacturing method of the dust removal roll as described in said [ 1 ].

According to the method for manufacturing a dust removal roll of the present invention, it is particularly suitable for removing dust adhering to a printed circuit board, leaving dust, spreading a cutting line in the winding direction, and rising from the outer surface of the roll in the vertical direction. generation of reservoir dust due to the step caused by the equal and duplicated peeling is effectively prevented, respectively, in the case of peeling and cutting spent outermost peripheral portion (the updated portion) along line Rutotomoni, cleavage of the updated portion, A dust- removing roll that can be easily peeled can be easily and efficiently manufactured .

  Hereinafter, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

First, a dust removal roll (hereinafter, simply referred to as a “dust removal roll”) suitable for removing dust attached to a printed circuit board manufactured by the method for producing a dust removal roll of the present invention will be described. To do. Figure 1 is a perspective view showing an embodiment of a dust removal roll manufactured by the manufacturing method of the dust removal roll of the present invention, FIG. 2 is an enlarged view of a portion of the portion A in FIG. 1 3 is a partially enlarged view of part B in FIG. 2, and FIG. 4 is a perspective view showing a state in which a part of the dust removal roll shown in FIG. 1 is unwound.

As shown in FIGS. 1 to 4, a dust removal roll 10 manufactured according to the present embodiment has a pressure-sensitive adhesive tape 1 having a pressure-sensitive adhesive surface 11 wound around a core 2 with the pressure-sensitive adhesive surface 11 as an outer surface. In addition, the dust removing roll 10 can be used repeatedly by peeling the used outermost peripheral surface of the adhesive surface 11 and using the newly exposed outer surface. The pressure-sensitive adhesive tape 1 has a plurality of continuous linear cutting lines (continuous cutting lines) 12 extending in the width direction from end to end at predetermined intervals in the winding direction. In a state of being wound around the core 2, it is arranged so that the interval L between the continuous cutting lines 12 increases sequentially toward the outer peripheral side so as to overlap at substantially the same position (see FIG. 2) (in FIG. 3, the outer peripheral side The three continuous cutting lines 12a, 12b, and 12c are shown in this order, and the outer peripheral side interval L1 is set larger than the adjacent core side interval L2). The portion is configured to be in close contact with the outer surface without rising in the vertical direction and without spreading in the winding direction.

  FIG. 5 is a perspective view showing a state where the cut portion of the continuous cutting line 12 swells in the vertical direction from the outer surface and spreads in the winding direction. As shown in FIG. 5, when the cut portion of the continuous cutting line 12 forms a bulging step 13 in the vertical direction from the outer surface and spreads in the winding direction, as described above, The smoothness of rotation is impaired (generation of noise, etc.), and it becomes difficult for the dust to adhere to the adhesive surface 11 in the vicinity of the portion, and dust is left behind.

On the other hand, in the case of the dust removal roll 10 manufactured according to the present embodiment, the cut portion of the continuous cutting line 12 is in close contact with the outer surface without rising in the vertical direction and without spreading in the winding direction. Since it is configured, it is possible to effectively prevent dust adhesion and the occurrence of dust accumulation.

  As shown in FIG. 3, the adhesive tape 1 is preferably composed of a substrate 1a, an adhesive layer 1b (the surface of which forms the adhesive surface 11) and, if necessary, a release agent layer 1c. Can be mentioned. Examples of the base material 1a constituting the adhesive tape 1 include paper, plastic film, cloth, and other materials. From the viewpoint of preventing generation of paper dust, plastic film is preferable. The width of the substrate 1a is preferably selected as appropriate according to the width of the printed circuit board to be dust-removed, for example, but is usually preferably about 400 to 900 mm.

  The pressure-sensitive adhesive layer 1b constituting the pressure-sensitive adhesive tape 1 is formed on the surface of the substrate 1a. Examples of the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 1b include rubber-based, acrylic-based, and other pressure-sensitive adhesives. Although there is no restriction | limiting in particular as thickness of the adhesive layer 1b, For example, 10-20 micrometers is preferable. On the adhesive surface 11 of the adhesive layer 1b (or on the surface opposite to the adhesive layer 1b of the substrate 1a), the release agent layer 1c may be selected depending on the type of the adhesive constituting the adhesive layer 1b. Is preferably formed. In this case, the release agent layer 1c may be formed on the surface opposite to the surface on which the pressure-sensitive adhesive layer 1b of the substrate 1a is formed. When the release agent constituting the release agent layer 1c is selected, it is preferable to determine the release agent in consideration of both the prevention of the peeling portion of the adhesive tape 1 from falling off and the ease of peeling.

  When wound around the core 2, the base material 1a constituting the adhesive tape 1 was kiss-cut in the width direction of the adhesive tape 1 so that the length of one turn was peeled for each turn (surface of the cut surface). A continuous cutting line 12 (cut in a state of being in close contact with each other) is formed. Since the diameter of the dust removal roll 10 increases as the pressure-sensitive adhesive tape 1 is wound around the core 2, the distances L1, L2 between the adjacent continuous cutting lines 12a, 12b, 12c are also closer to the outer peripheral side. It is formed sequentially so as to be longer (L2 <L1) (see FIG. 4).

The continuous cutting line 12 is configured such that when the adhesive tape 1 is wound around the core 2, the interval between the continuous cutting lines is always equal to the exposed outer periphery of the dust removal roll 10. For this purpose, if the continuous cutting line 12 is formed so as to be slightly beyond the immediately preceding continuous cutting line, the adhesive tape 1 to which dust has adhered is peeled off by the continuous cutting line 12. In this case, the adhesive surface 11 to which dust is attached does not remain in part.

It is preferable to protect the adhesive layer by winding release paper on the outermost peripheral side of the dust removing roll 10 as necessary.
When dust adheres to the adhesive surface 11 and the dust removal effect decreases, for example, a continuous cutting line located at the outermost end of the adhesive tape 1 using a jig with a twisting spatula (not shown) It is preferable to peel by inserting a spatula into the 12 cut portions.

  Although there is no restriction | limiting in particular as the core 2 used for this Embodiment, For example, what consists of paper, a plastic film, and another material can be mentioned. In addition, when the adhesive tape 1 can be wound without destroying the shape of the dust removal roll 10, the winding core 2 may not be used.

Next , an embodiment of a method for producing a dust removal roll according to the present invention will be described.

  FIG. 6 is an explanatory view showing an embodiment of a method for producing a dust removal roll according to the present invention, and FIG. 6 (a) unwinds an original fabric roll in which a continuous cutting line is formed on the original fabric adhesive tape. (B) shows a state before cutting off both end portions of the original fabric roll, and (c) shows a state where both end portions of the original fabric roll are cut off to form dust removing rolls. The dust removing roll manufacturing method of the present embodiment is configured such that an adhesive tape having a predetermined width having an adhesive surface is wound around a core with the adhesive surface as an outer surface, and the used outermost peripheral surface of the adhesive surface is peeled off. A method of manufacturing a dust removal roll (see FIGS. 1 to 5) that can be used repeatedly by using a newly exposed outer surface, and a step of forming a continuous cutting line 22 on the raw fabric adhesive tape 21 And a step of forming the roll 20 and a step of forming the dust removal roll 10 by cutting off both end portions E of the roll 20. Hereinafter, it demonstrates concretely for every process. In the present embodiment, the components used in the dust removal roll 10 described above can be used as they are.

(Process of forming continuous cutting lines on adhesive tape)
First, as shown in FIG. 6A, in the present embodiment, a predetermined distance D is applied to each of the raw fabric adhesive tape 21 wider than the adhesive tape 1 constituting the final dust removal roll 10 from both ends. A continuous line-shaped cutting line (continuous cutting line) 22 (22a, 22b, 22c) extending in the width direction while leaving the part (non-cutting part, that is, both end parts E of an original fabric roll described later), In a state where the original fabric adhesive tape 21 is wound around the core 2, the intervals between the continuous cutting lines 12 are sequentially increased toward the outer peripheral side so as to overlap at substantially the same position (see FIG. 6C). In FIG. 6A, three continuous cutting lines 22a, 22b, and 22c are shown in order from the outer peripheral side, and the outer peripheral side interval L1 is larger than the adjacent core side interval L2. It shows an example of setting).

  Here, as the raw fabric adhesive tape 21, the same material as the above-mentioned adhesive tape 1 can be used except that the width is wider than that of the adhesive tape 1.

  As a method for forming the continuous cutting line 22, for example, a method using a die cut roll (not shown) can be cited as a preferred example. Specifically, a method of forming the continuous cutting line 22 by passing the raw fabric adhesive tape 21 between a die cut roll in which a blade having a shape of the continuous cutting line 22 is embedded on the surface of the roll and the silicone roll is mentioned. it can.

(Process for forming the raw fabric roll)
Next, as shown in FIG.6 (b), in this Embodiment, the original fabric adhesive tape 21 in which the multiple continuous cutting line 22 was formed was wound around the core 2, and the original fabric roll 20 was made. Form.

  Here, the raw fabric roll 20 can be configured in the same manner as the dust removal roll 10 except that the width is wider than the dust removal roll 10.

  The step of forming the original fabric roll 20 may be performed separately from the step of forming the continuous cutting line 22 on the above-mentioned original fabric adhesive tape 21, or the above-mentioned original fabric adhesion by combining rolls continuously. You may carry out continuously from the process of forming the continuous cutting line 22 in the tape 21. FIG.

  In this case, the raw fabric adhesive tape 21 wound around the core 2 has a continuous cutting line 21 extending in the width direction at the center, but non-cut portions at both ends (both end portions E to be cut off later). Since this portion receives the tension, it is prevented that the original fabric adhesive tape 21 is broken by the tension or the cut portion of the continuous cutting line 22 is spread, and a smooth winding operation is realized.

(Process of cutting off both ends of the raw roll to form a dust removal roll)
Next, as shown in FIG.6 (c), in this Embodiment, from the original fabric roll 20, the non-cut | disconnecting part (original fabric roll 20 of the original fabric roll 20) in the both ends of the original fabric adhesive tape 21 which comprises the original fabric roll 20 is shown. Both end portions E) are cut off to form the dust removal roll 10 having the above-mentioned characteristics. That is, the adhesive tape 1 having a plurality of continuous cutting lines 22 extending in the width direction from end to end at a predetermined interval in the winding direction is wound around the core 2, and the adhesive tape 1 is wound around the core 2. In the rotated state, the continuous cutting lines 22 are arranged so that the interval between the continuous cutting lines 22 gradually increases toward the outer peripheral side so that the continuous cutting lines 22 overlap at substantially the same position (see FIG. 6A). The cut portion of the line 22 forms the dust removing roll 10 that is configured to closely contact the outer surface without rising in the vertical direction and without spreading in the winding direction.

  Examples of a method for cutting off both end portions E of the raw fabric roll 20 include a method using a push slitter.

As shown to Fig.6 (a), in this Embodiment, the ratio ( ( D) of the predetermined distance (D) of the non-cut | disconnecting part in the original fabric adhesive tape 21 with respect to the width | variety (W) of the original fabric adhesive tape 21 Although / W ) × 100) depends on the material of the raw adhesive tape, it is usually preferably 4 to 8%, more preferably less than 3%. If it is less than 4%, in the step of forming the original fabric roll 20, the original fabric adhesive tape 21 wound around the core 2 may be broken by tension, or the cut portion of the continuous cutting line 22 may spread. is there. Further, if it exceeds 8%, raw materials may be wasted.

  Hereinafter, the present invention will be described more specifically with reference to examples.

Example 1
A base sheet was obtained by applying a silicone release agent to a 27 μm thick trephane (OPP) film as a base material to form a release surface. An acrylic pressure-sensitive adhesive was applied to the surface opposite to the peeled surface of the base sheet to a thickness of 10 μm to form an adhesive surface, and a single-sided adhesive tape as a raw fabric adhesive tape was obtained. This single-sided adhesive tape was cut into a width of 700 mm to obtain a roll-sided single-sided adhesive tape. Next, in order to unwind the roll-wrapped single-sided adhesive tape and put a continuous cutting line (kiss cut) in the width direction of this single-sided adhesive tape, the single-sided adhesive tape is passed between the silicone roll and the die-cut roll, and the width In the direction, a distance of 50 mm from each end was placed, and a continuous cutting line of 600 mm was sequentially formed in the center portion at intervals of the outer circumference of the single-sided adhesive tape. Next, the single-sided pressure-sensitive adhesive tape on which the continuous cutting line was formed was wound around a winding core so that the pressure-sensitive adhesive surface was on the outside, thereby forming an original fabric roll. Next, in order to make a 700 mm wide original fabric roll 600 mm wide, both end portions were cut off with a width of 50 mm to obtain a dust removal roll. The dust removal roll thus obtained was subjected to a dust removal test with a clean roller (trade name: RY-502Z) manufactured by Rayon Kogyo Co., Ltd., in a state where dust adhered to the adhesive tape of the dust removal roll. The ease of peeling of the updated part of the adhesive tape, the change in elongation of the tape, the state of the cut surface and workability were evaluated. The results are shown in Table 1.

(Comparative Examples 1-3)
In the adhesive tape narrower than the original adhesive tape, perforations and discontinuous cutting lines were formed instead of continuous cutting lines, and no continuous cutting lines were formed (both ends of the original roll using a cutting blade) Example 1 was performed except that the part was cut. The dust removal roll thus obtained was subjected to a dust removal test with a clean roller (trade name: RY-502Z) manufactured by Rayon Kogyo Co., Ltd., in a state where dust adhered to the adhesive tape of the dust removal roll. The ease of peeling of the updated part of the adhesive tape, the change in elongation of the tape, the state of the cut surface and workability were evaluated. The results are shown in Table 1.
