Description

  The present invention relates to an electrostatic dust adsorber and a method for manufacturing the same.

In convenience stores, general merchandise stores, and the like, electrostatic dust adsorbing tools (hereinafter referred to as electrostatic hats) are widely used to remove dust and the like attached to products placed on display shelves. The electrostatic hat is obtained by attaching stretched defibrated yarn or non-woven fabric (hereinafter referred to as an adsorbent) made of polypropylene, which is easily charged with static electricity, to a handle bar. Because electrostatic duster dust is adsorbed to the adsorbent just by lightly touching the surface of the article, unlike small electric and vacuum cleaners, etc. And fine dust can be removed. As the form of the electrostatic flap, the adsorbent is formed in a tuft-like shape by winding a warp with the end portion of the adsorbent upright (refer to Patent Document 1), or a strip-shaped adsorbent provided with a large number of cuts. Is known that is wound around a handle bar in a spiral shape (see Patent Document 2).

≪Method for manufacturing electrostatic flyer≫
Hereinafter, with reference to FIG. 4 (a), (b), the manufacturing method of the electrostatic group 1 is demonstrated.
In manufacturing the electrostatic sheet 1, the assembly operator first wraps the double-sided adhesive tape 12 around the rear end of the second dust adsorbing portion 4 as shown in FIG. After the end of the warp yarn 10b of the tufted material 10 is adhered to the second dust adsorbing portion 4, a predetermined amount of the rear portion of the second dust adsorbing portion 4 is inserted into the handle bar 2 while the warp yarn 10b enters the slit 2a. In addition, since the handle 2 is opened by the slit 2a in the left-right direction in the figure, the second dust adsorbing portion 4 can be easily fitted. When the assembly operator finishes fitting the second dust adsorbing portion 4 into the handle 2, the assembly operator drives the resin pin 7 into the locking hole 2 b of the handle 2 using a tool (not shown). The resin pin 7 driven in from the locking hole 2b passes through the second dust adsorbing portion 4 and penetrates the surface on the opposite side of the handle rod 2, whereby the second dust adsorbing portion 4 is fixed to the handle rod 2. .

  Next, as shown in FIG. 4 (b), the assembling worker winds the warp 10 b of the tufted material 10 around the handle bar 2 in a spiral shape with a predetermined pitch. Thereby, the handle bar 2 is tightened, the slit 2 a is closed, and the second dust adsorbing portion 4 is firmly fixed by the handle bar 2. When the winding of the warp yarn 10b progresses, the weft bundle 10a of the tuft material 10 is erected in a state where it is densely packed around the handle bar 2, and the first dust adsorbing portion 3 is formed in a tuft shape. When the assembly operator finishes winding the tuft material 10, the end of the tuft material 10 is fixed with an adhesive tape (not shown), and then the stopper pin 8 is press-fitted into the pin hole 2 c of the handle 2. The press-in of the stopper pin 8 may be performed before the step of fitting the second dust adsorbing portion 4 into the handle bar 2 (that is, with respect to the single handle bar 2).

  Next, the assembly operator inserts the cover 5 from the rear end of the handle bar 2 and advances the cover 5 to a position fixed by the stopper pin 8. Thereby, the rear end of the first dust adsorbing portion 3 is pressed forward by the cover 5, and the weft bundle 10 a of the tuft material 10 is tilted forward, so that the shape of the first dust adsorbing portion 3 is adjusted. Thereafter, the assembly operator inserts the end cap 6 into the rear end of the handle bar 2, passes the suspension string 9 through the suspension string holes 2 d and 6 c of the handle bar 2 and the end cap 6, and ends the suspension string 9. The assembly work is completed by connecting the parts.

<< Operation of Embodiment >>
When the cleaning operator removes dust attached to the article or shelf using the electrostatic scraper 1, the surface of the article or shelf is picked up by the first dust adsorption unit 3, and the first dust is adsorbed by the generated static electricity. The part 3 is made to adsorb dust. Since the first dust adsorbing section 3 has a tuft shape, an operation of stroking an article or the like is easy, and since the total amount of the weft bundle 10a (adsorbent) is large, a relatively large amount of dust can be adsorbed. On the other hand, when the cleaning operator removes dust accumulated in the gaps between the articles, the corners of the display shelf, etc., the second dust adsorbing part 4 strokes the part and makes the second dust adsorbing part 4 by the generated static electricity. Adsorb dust. Since the second dust adsorbing portion 4 has a spike shape, the yarn bundle 4a can easily reach a narrow portion, and dust can be efficiently removed.

  In the case of this embodiment, the weft bundle 10a constituting the first dust adsorbing section 3 and the yarn bundle 4a constituting the second dust adsorbing section 4 are flexible, tough and lightweight stretched defibrated yarns made of polypropylene. Therefore, when dust is removed, it does not tear off, and the adsorbed dust can be easily removed with a neutral detergent or the like, and the electrostatic scraper 1 becomes lighter and the fatigue of the cleaning operator is reduced. .

  Although the description of the specific embodiment is finished as described above, the present invention is not limited to the above embodiment and can be widely modified. For example, although the above-described embodiment is an application of the present invention to electrostatic paper, it may be applied to a duster or the like that removes automobile dust. In the above embodiment, polypropylene stretched defibrated yarn is used as the material for the first dust adsorbing part and the second dust adsorbing part. It may be used, or may be a strip having a large number of cuts. In the above embodiment, the second dust adsorbing portion is integrated with the handle, but the material and hardness of the second dust adsorbing portion are changed or changed depending on the use, or only the second dust adsorbing portion is replaced with a new one when consumed. The second dust adsorbing portion may be detachable with respect to the handle so that it can be exchanged. Further, the specific shapes of the first dust adsorbing portion and the second dust adsorbing portion, the specific configuration of the electrostatic texture, and the like can be changed as appropriate without departing from the spirit of the present invention.
