Description

  The present invention relates to a method for producing a static elimination brush, and more particularly, to a method for producing a static elimination brush installed in a paper transport section of an OA device such as a printer, a copying machine, or a facsimile.

  Conventionally, this type of static elimination brush is formed by sandwiching and bonding a plurality of conductive wires (fibers) in a sandwich between a conductive surface tape and a non-conductive back surface tape (paper material). . When manufacturing this static elimination brush, first, as shown in FIG. 5, between the left side 1a and right side 1b of the box-type frame 1, a plurality of double-sided tapes 2, 2,. The left and right end portions of the double-sided tape 2, 2... Are stuck to the left side portion 1a and the right side portion 1b.

  Next, as shown in FIG. 6, the conductive wire 3 is wound around a plurality of double-sided tapes 2, 2... By winding the conductive wire 3 between the upper side 1c and the lower side 1d of the frame 1 a predetermined number of times. Fasten in the orthogonal direction. Thereafter, as shown in FIG. 7, aluminum single-sided tapes 4, 4... Are attached to the double-sided tapes 2, 2.

  Subsequently, the double-sided tapes 2, 2... Are peeled off from the single-sided tapes 4, 4..., And instead of the double-sided tapes 2, 2,. 5 is affixed to the back side of the single-sided tape 4, 4.

  Thereafter, the single-sided tapes 4, 4,... And the conductive wire 3 are cut along the inner peripheral shape of the frame 1 with a die blade (not shown), thereby removing the frame 1 from the frame 1 as shown in FIG.

  The above prior art requires at least eight steps to manufacture the static elimination brush, so that the manufacturing time is increased and the manufacturing cost is increased. Furthermore, since the conductive wire is sandwiched and stuck between the single-sided tape that is the attachment portion and the paper material, there is a problem that the conductive wire is easily removed from the attachment portion, and it is difficult to expect a sufficient static elimination effect. .

  In addition, in order to increase the fixing force of the conductive wire to the mounting portion, a method of fixing the conductive wire to the metal plate with an adhesive resin is also employed. However, in this case, a large number of processes are required. In addition, the material cost of the adhesive resin and the metal plate is increased.

  Therefore, there are technical problems to be solved in order to shorten the manufacturing time and cost of the static elimination brush and to surely prevent the removal of the conductive weft as the conductive wire. The present invention aims to solve this problem.

The present invention has been proposed to achieve the above object, and the invention according to claim 1 is a narrow fabric woven by warps and wefts, and the narrow fabric is formed on both right and left sides. Warp yarns are arranged, a space is provided with a predetermined distance therebetween, and both ends are woven by conductive wefts woven into the warp yarns on both sides, and further conductive on one side of the warp yarns on both sides. Alternatively, in the static elimination brush manufacturing method of cutting the weft after pasting a non-conductive tape, the warp is at least three on both the left and right sides, and the weft is placed between the left and right warps. While turning back and forth alternately, the folded portion is woven back and forth twice on the warp to form a ladder-like woven fabric, and each woven portion of the weft is provided so as to incline toward the tape side. Affix the tape to the side and It is contacted in common to each woven portions of the weft, and thereafter provides a discharge brush manufacturing methods for cutting the lateral direction central portion of the weft yarn into the warp and parallel to the longitudinal direction.

According to this configuration, first, at least three warps are arranged on both the left and right sides, and a space portion is provided with a predetermined interval therebetween. Next, for example, after weaving one end of the weft to the left warp, the weft is interlaced with the right warp, and the intersection is woven into the warp.
In the same manner, the folded portion is woven into the warp yarn while the weft yarn is alternately folded a predetermined number of times between the left and right warp yarns. At that time, each weaving portion of the weft is formed so as to be inclined toward the tape side. As a result, a ladder-like woven fabric is obtained in which wefts are woven alternately on the left and right sides.
Next, a conductive or non-conductive tape is attached to one side surface of each warp, and the tape is brought into contact with each weaving portion of the weft. Thereafter, the neutralizing brush is manufactured by cutting the central portion in the left-right direction of the weft in the longitudinal direction parallel to the warp.

The invention according to claim 2 is a narrow woven fabric woven by warp and weft, wherein the narrow woven fabric has warp yarns arranged on both the left and right sides, and a space is provided with a predetermined distance therebetween. and, it is woven by conductive weft yarns both ends are woven into the opposite sides of the warp, after cutting the weft yarn, formed by attaching a conductive or non-conductive tape on one side of the both sides of the warp In the static elimination brush manufacturing method, at least three warps on each of the left and right sides are woven, and the folded portion is woven twice or more times in the warp while the wefts are folded back alternately on the left and right sides. Forming a ladder-like woven fabric, and each weaving portion of the weft is provided so as to incline toward the tape side, and a central portion in the left-right direction of the weft is cut in a longitudinal direction parallel to the warp, Adhering the tape to one side of the warp Providing discharge brush manufacturing method of contacting in common to each woven portions of the weft the tape.

According to this configuration, and the invention of claim 1 wherein, after cutting the conductive weft yarns, so that the adhering a conductive or non-conductive tape only difference is, weaving of the warp and weft Then , the static eliminating brush is manufactured in approximately three steps of tape sticking and weft cutting .

  The invention according to claim 3 provides the method for producing a static elimination brush according to claim 1 or 2, wherein each woven portion of the conductive weft is woven into the warp by reciprocating a plurality of times.

  According to this configuration, each weaving portion of the conductive weft with respect to the warp is reciprocated twice or more to be woven in a zigzag, so that the fixing force of the conductive weft to the warp is further increased.

According to the first aspect of the present invention, each weaving portion of the weft is formed so as to incline toward the tape side, so that each weaving portion of the weft reliably contacts the tape. An effect can be obtained in which the current moves more smoothly to the side.
In the past, it took 8 or more steps to manufacture a neutralizing brush, but only 3 steps of weaving warp and weft, sticking tape and cutting weft were used to weave many wefts into warp. Since the two neutralizing brushes are manufactured at the same time , the manufacturing time can be greatly reduced. In addition to reducing the number of manufacturing processes, there is no need for fixing resins or metal plates. Cost reduction.

In addition, each weaving part of the weft is fold-backed and woven into at least three warps arranged on the left and right sides, changing the direction to the left and right more than three times. Combined with being clamped and fixed between the warps, the fixing force of the weft with respect to the warps increases markedly. Therefore, it is possible to reliably prevent the conductive weft from coming off from the warp, and even if it is used, a good static elimination effect can be exhibited over a long period of time.

In the invention according to claim 2, as in the invention according to claim 1 , each weaving portion of the weft is formed so as to be inclined toward the tape side, so that each weaving portion of the weft is electrically connected to the tape. Therefore, the current smoothly moves from the weft to the tape when using the brush.
In addition, each weaving portion of the weft is woven into the warp yarn by changing the direction to the left and right at least three times at the folded portion, so that each weaving portion of the weft is sandwiched and fixed between the tape and the warp. Together, the fixing force of the weft against the warp is greatly increased. Therefore, even when the neutralizing brush is used for a long period of time, there is no possibility that the weft will come off from the warp, and a sufficient neutralizing effect can be reliably obtained.
Furthermore, two neutralizing brushes that are made by weaving a large number of wefts into warp yarns are manufactured at the same time in approximately three steps of weaving warp and weft yarns, attaching the tape, and cutting the weft yarns. Compared to the number of processes, the manufacturing time is significantly reduced. Furthermore, in addition to the reduction in the number of processes, since no fixing resin or metal plate is required, the total production cost including material costs is greatly reduced.
In addition, after the conductive weft is cut and the warp yarns on both sides are separated, a conductive or non-conductive tape is attached to the warp yarn, so that the tape can be attached easily.

  In the invention described in claim 3, since the fixing force of the conductive weft to the warp is further strengthened, compared with the effect of the invention described in claim 1 or 2, the effect of preventing the conductive weft from coming off can be further enhanced. it can.

The purpose of the present invention is to reduce the manufacturing time and cost of the static eliminating brush and to prevent the conductive weft (conductive wire) from coming off reliably. The narrow woven fabric has warp yarns arranged on both left and right side portions, a space portion is provided between the warp yarns, and both ends are woven with conductive weft yarns woven into the warp yarns on both sides. made, further, after adhering the both sides of the conductive or non-conductive tape on one side of the warp, the discharge brush manufacturing methods for cutting the weft yarn, the left and right sides of each said warp of at least three The wefts are folded back and forth alternately between the left and right warp yarns, and the folded portion is woven back and forth twice to form a ladder-shaped woven fabric, and each weaving portion of the weft yarns To tilt toward the tape side The tape is attached to one side of the warp, and the tape is brought into contact with each weaving portion of the weft in common, and then the center of the left and right direction of the weft is parallel to the warp. This was realized by cutting into pieces.

  A preferred embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, the static elimination brush 10 which concerns on a present Example is comprised by the narrow fabric. The narrow woven fabric is referred to as a non-conductive warp (hereinafter referred to as “warp”) 12 serving as an attachment portion 11 and a plurality of conductive wefts (hereinafter referred to as “weft”) woven on the warp 12. ) 13, 13... In the illustrated example, each weaving portion of the weft yarns 13, 13...

  The material of the wefts 13, 13... Is not particularly limited as long as it has the required conductivity, and for example, conductive fibers such as stainless fibers, carbon fibers, amorphous fibers, zirconia fibers, etc. can be used as appropriate.

  Further, a conductive or non-conductive double-sided tape 14 made of a metal such as aluminum is attached to one side surface of the warp 12. For this reason, each weaving part of the wefts 13, 13... Is in electrical contact with the conductive double-sided tape 14. In place of the double-sided tape 14, a conductive or non-conductive single-sided tape may be used.

  The neutralizing brush 10 is used, for example, by attaching a double-sided tape 14 to a paper conveying portion (earth metal portion) of an OA device such as a printer, a facsimile machine, or a copying machine. Thus, when the sheet passes while contacting the front ends of the wefts 13, 13,..., The static electricity charged on the sheet moves to the double-sided tape 14 side through the wefts 13, 13,. The

  Next, the manufacturing method of the static elimination brush 10 will be described in detail. First, the warp yarns 12 are arranged on both the left and right sides, and a space is provided with a predetermined interval therebetween. In this case, the number of the left warp yarns 12 and the number of the right warp yarns 12 are the same (four in the illustrated example). Next, as shown in FIG. 2, after weaving one end of the weft 13 on the left warp 12, the weft 13 is interlaced with the right warp 12 and the interlaced portion is woven into the warp 12.

  In the same manner, the folded portion is woven into the warp 12 while the weft 13 is folded back and forth alternately between the left warp 12 and the right warp 12 a predetermined number of times. As a result, a ladder-like woven fabric obtained by weaving the wefts 13 alternately on the left and right sides of the respective warp yarns 12 is obtained.

  The number of reciprocating weaves in each weaving portion of the weft 13 is not limited to two, but can be arbitrarily determined according to the length and number of the wefts 13 and warps 12. For example, as shown in FIG. 3, each weaving portion of the weft 13 can be woven by reciprocating three or more times. In this case, as shown in FIG. 4, each weaving portion of the weft 13 is woven so as to be positioned on the near side in FIG. 4 with respect to the two inner sides of the warp 12.

  Next, a conductive or non-conductive double-sided tape (or single-sided tape) 14 is attached to one side surface of each warp yarn 12, and the double-sided tape 14 is in contact with each weaving portion of the wefts 13, 13,. Let Thereafter, the central portion in the left-right direction of the weft 13 is cut along the cut line L in the warp direction, that is, the longitudinal direction parallel to the warp yarn 12. The left and right width of the double-sided tape 14 is narrower than the left and right widths of the wefts 13, 13,. Furthermore, it is preferable to form each weaving part of the wefts 13, 13... To have a slight angle so as to be inclined toward the double-sided tape 14 side. In this way, each weaving portion of the wefts 13, 13... Reliably contacts the double-sided tape 14, so that the current smoothly moves from the wefts 13, 13.

  Thus, as shown in FIG. 1, two neutralizing brushes 10 formed by weaving a large number of wefts 13 on warps 12 are manufactured simultaneously. In addition, you may perform the sticking process of the double-sided tape 14 after the cutting process of the weft 13.

  As described above, in this embodiment, since the weft (conductive wire) 13 is firmly woven into the warp 12 as the attachment portion 11, each woven portion of the weft 13 is sandwiched and fixed between the double-sided tape 14 and the warp 12. Combined with this, the fixing force of the weft 13 to the attachment portion 11 is significantly increased as compared with the conventional pasting method.

  In particular, each weaving portion of the weft 13 is woven by reciprocating the warp 12 at least twice, so that the fixing force of the weft 13 with respect to the warp 12 increases more than twice. Therefore, even when the neutralizing brush 10 is used for a long period of time, there is no possibility that the weft 13 will come off from the attachment portion 11, and a sufficient neutralizing effect can be reliably obtained.

  In addition, according to the present embodiment, the two neutralizing brushes 10 are simultaneously manufactured by only three steps of weaving the warp yarns 12 and the weft yarns 13, attaching the double-sided tape 14, and cutting the weft yarns 13. As a result, the number of processes is reduced to less than half compared with the prior art, and the manufacturing time is greatly reduced. Furthermore, in addition to the reduction in the number of processes, since no fixing resin or metal plate is required, the total production cost including material costs is greatly reduced.

  The present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
