The front view of the roll-shaped brush which has a brush part from which the length of fluff differs in multiple steps.

Hereinafter, the manufacturing apparatus and manufacturing method of the roll-shaped brush of this invention are demonstrated based on FIGS.
As shown in FIG. 1, the roll-shaped brush 11 manufactured with the manufacturing apparatus and manufacturing method of this invention is the support shaft 12 which consists of metal round bars, and the brush part 13 ( 13A, 13B). In addition, the fluff which comprises brush part 13A and brush part 13B is all straight hair shape, and the level | step difference is formed between brush part 13A and brush part 13B.

  And the roll-shaped brush 11 which has a level | step difference in this brush part 13 is obtained by carrying out the shearing process of the roll-shaped brush 11A in which the length of the fluff shown in FIG. 2 is uniform, and there is no level | step difference in the brush part 13 (13C). Therefore, the manufacture of the roll-shaped brush 11A having no step in the brush portion 13 will be described first, and then the shearing process will be described.

  First, the roll-shaped brush 11A having no step in the brush portion 13 is manufactured as follows. First, as shown in FIG. 3, a plurality of straight hairs 21 extending from the surface of the base fabric 20 are formed by weaving brush yarn into the base fabric 20 made of a strip-shaped woven fabric by, for example, pile weaving.

  Subsequently, a belt-like brush material 23 is manufactured by applying a synthetic resin coating agent to the back side of the base fabric 20 to form the coating layer 22. The coating layer 22 is impregnated with the coating agent between the yarns of the base fabric 20 and hardened, thereby suppressing fraying of the base fabric 20 and playing a role of joining the fluff 21 and the base fabric 20. .

  Next, as shown in FIG. 4, the belt-like brush member 23 is joined to the support shaft 12 whose surface is coated with an adhesive while being wound in a spiral shape. Thereby, the roll-shaped brush 11A in which the portion around which the brush material 23 is wound constitutes the brush portion 13C having no step is obtained. In addition, the length along the axis S1 direction of the brush portion 13C can be arbitrarily adjusted by increasing or decreasing the number of windings of the brush material 23, and the length of the fluff 21 can change the length of the brush yarn. Can be adjusted arbitrarily.

Next, the shearing process for forming a level | step difference in the brush part 13 is demonstrated.
As shown in FIG. 5, the shearing process is performed using a shearing device 24 as a cutting means for cutting the fluff 21 and a cutting position adjusting device 25 as a roll brush manufacturing device.

  As shown in FIG. 6, the shearing device 24 includes a spiral blade 32 having a substantially cylindrical shape that is rotatably provided around a rotation shaft 31, and a fixed blade that is provided so as to extend in the axis S <b> 2 direction of the rotation shaft 31. 33. In the shearing device 24, as the spiral blade 32 rotates, the fluff 21 disposed between the spiral blade 32 and the fixed blade 33 is cut by a shearing action.

  On the other hand, the cutting position adjusting device 25 includes a support member 34 that supports the support shaft 12 of the roll-shaped brush 11A so that the axis S1 direction of the roll brush 11A and the axis S2 direction of the rotation shaft 31 are parallel to each other, and a resin material. And a cover member 35 that is a sheet-like member. The support member 34 is configured to be movable in a direction approaching and separating from the shearing device 24.

  The cover member 35 is disposed between the shearing device 24 and the support shaft 12 supported by the support member 34, and as shown in FIG. 7, a cover portion 36 capable of selectively covering a part of the brush portion 13 and a brush And an opening 37 for selectively exposing the tip side of the portion 13. The opening 37 is provided corresponding to a portion that cuts the fluff 21 short, and the width Wd, arrangement, number, etc. in the direction of the axis S1 can be arbitrarily changed.

  Since the cover member 35 is made of a resin material and can be easily processed, the width Wd of the opening 37 and the interval between the adjacent openings 37 can be reduced to about 1 mm. That is, the position and interval of the step of the brush portion 13 can be set at the millimeter level. And the brush part 13 from which the length of the fluff 21 differs in several steps can be formed by performing the shearing process of multiple times using the cover member 35 from which the size and arrangement | positioning of the opening part 37 differ.

  The cover member 35 preferably has a smooth surface and flexibility. If it does so, even if it contacts with the rotating spiral blade 32, it is because the spiral blade 32 slips or the cover member 35 bends, and thereby mutual damage can be suppressed.

Next, a specific process of shearing will be described.
First, prior to the shearing process, the fluff 21 of the roll brush 11A is raised with steam and centrifugal force. Then, the spindle 12 of the roll brush 11 </ b> A with the fluff 21 raised is attached to the support member 34, and the cover member 35 is attached to the cutting position adjusting device 25.

  Next, the position of the support member 34 is adjusted so that the tip portion of the fluff 21 exposed from the opening 37 of the cover member 35 is disposed between the spiral blade 32 and the fixed blade 33. That is, the fluff 21 to be cut is determined by the arrangement of the opening 37 of the cover member 35, and the cut length of the fluff 21 is determined by the position of the support member 34.

  Then, the tip of the fluff 21 exposed from the opening 37 by the shearing action of the spiral blade 32 and the fixed blade 33 is caused by rotating the support shaft 12 of the roll brush 11A and the rotation shaft 31 of the spiral blade 32 at different rotational speeds. The side is cut off. In the present embodiment, after the brush portion 13A is formed by the first shearing process using the cover member 35, the brush part 13B is formed by the second shearing process without using the cover member 35.

  That is, when the first shearing process is performed using the cover member 35 provided with the three openings 37, as shown in FIG. 8, the brush portion 13C held without being cut and the tip is short. The cut brush portions 13A are alternately arranged to form steps.

  Subsequently, the cover member 35 is removed from the cutting position adjusting device 25, and the support member 34 is moved away from the shearing device 24, so that the second shearing is performed to cut the tip side of the fluff 21 at the dotted line position in FIG. Apply processing. Then, the front end portion of the brush portion 13C is cut to form a straight hair-like brush portion 13B whose length is adjusted. Thereby, the roll-shaped brush 11 shown in FIG. 1 is completed. Although the second shearing process can be omitted, the length of the fluff 21 can be accurately defined by performing the second shearing process.

  The roll-shaped brush 11 manufactured in this way can be used suitably as a roller for banknote conveyance as shown, for example in FIG.9 and FIG.10. That is, when the banknote is conveyed, the brush portion 13A is covered with the covering member 40 having the opening 40a in order to expose only the brush portion 13B necessary for paper feeding. In such an application, if the cutting position adjusting device 25 of the present embodiment is used, the length of the fluff 21 of the brush portions 13A and 13B can be easily adjusted by changing the position of the support member 34, and the opening of the cover member 35 can be adjusted. The position of the step can be arbitrarily set by changing the arrangement and size of 37.

  Similarly, if shearing is performed while changing the position of the support member 34 in a plurality of stages using a plurality of cover members 35 having different arrangements and numbers of openings 37, as shown in FIG. 11 and FIG. The step of the portion 13 can be formed at an arbitrary position and size.

  Specifically, the roll-shaped brush 110 shown in FIG. 11 has straight hair-like brush portions 13 (13D, 13E, 13F, 13G) in which the lengths of the fluff 21 are stepwise different. And brush part 13D, 13E, 13F can be formed by performing the 1st-3rd shearing process sequentially using the cover member 35 which has the one opening part 37 from which width Wd differs, respectively. The brush portion 13G can be formed by a fourth shearing process that does not use the cover member 35.

  That is, the roll-shaped brush 110 is manufactured by performing four stages of shearing using three cover members 35 having different widths Wd of the openings 37. Note that the brush portion 13E can also be formed by a second shearing process using a cover member 35 having two openings 37 adjacent to the brush portion 13D. The brush portion 13F can also be formed by a third shearing process using a cover member 35 having two openings 37 adjacent to the brush portion 13E.

  Moreover, the roll-shaped brush 210 shown in FIG. 12 has the brush part 13 (13H, 13I, 13J) from which the length of the fluff 21 changes in steps. The brush portion 13H can be formed by a first shearing process using a cover member 35 having four openings 37. The brush portion 13I can be formed by a second shearing process using a cover member 35 having two openings 37. The brush portion 13J can be formed by a third shearing process that does not use the cover member 35. That is, the roll-shaped brush 210 is manufactured by performing a three-stage shearing process using the two cover members 35 having different positions and numbers of the openings 37.

  Thus, if the cutting position adjusting device 25 is used, the position of the step of the brush portion 13 can be arbitrarily set by changing the position and number of the opening portions 37 of the cover member 35. Further, by changing the width Wd of the opening 37, the width of the brush part 13 to be cut can be arbitrarily set at the millimeter level. Furthermore, the length of the fluff 21 to be cut can be arbitrarily set by changing the position of the support member 34. Therefore, the roll-shaped brush 11 having an arbitrary step in the brush portion 13 can be efficiently manufactured.

According to the embodiment described above, the following effects can be obtained.
(1) By selectively covering the brush portion 13 with the cover member 35 disposed between the shearing device 24 and the support shaft 12, the fuzz 21 that is not covered with the cover member 35 is selectively cut. Can do. Therefore, by changing the shape and arrangement of the cover member 35, it is possible to efficiently manufacture a roll brush having the brush portion 13 in which the lengths of the fluff 21 are stepwise different.

  (2) Since the cover member 35 is a sheet-like member made of a resin material, it is easy to process and has excellent cost performance. And the position of the level | step difference of the brush part 13 can be set in a millimeter level from the workability.

  (3) Since the cover member 35 has the opening 37 for selectively exposing the tip of the brush portion 13, the length and length of the fluff 21 are shortened by changing the position and size of the opening 37. Can be arranged arbitrarily.

  (4) Since the support member 34 that can support the support shaft 12 and is movable in the direction approaching or separating from the shearing device 24 is provided, the support shaft 12 and the shearing device are moved by moving the support member 34. The distance from 24 can be easily adjusted, and the length of the fluff 21 to be cut can be arbitrarily changed.

The above embodiment may be changed to another embodiment as described below.
The brush portion 13C of the roll brush 11A may be a loop brush in which the tip side of the fluff 21 is a loop. Then, the brush part 13A is formed by the first shearing process using the cover member 35, and the second shearing process is omitted, so that the tip of the fluff 21 is directly connected to the looped brush part 13C and the tip of the fluff 21. It is possible to efficiently manufacture the brush portion 13 in which the bristle brush portions 13A are alternately arranged to form a step. According to the brush portion 13 </ b> C having the looped tip side of the fluff 21, the load on the contacted body that comes into contact with the fluff 21 is reduced, and wear of the fluff 21 can be suppressed.

  The cover member 35 does not include the opening 37, and a plurality of the cover members 35 including the cover portion 36 are arranged at predetermined intervals in the direction of the axis S1, so that the tip side of the brush portion 13 is selectively exposed. Also good. In this case, by configuring the cover member 35 to be movable in the direction of the axis S1, the position of the fluff 21 to be cut can be easily changed without replacing the cover member 35.

  For example, the roll-shaped brush 110 shown in FIG. 11 can selectively cut the fluff 21 exposed near the center by covering both end portions in the direction of the axis S1 of the brush portion 13 with the two cover members 35. And brush part 13D, 13E, 13F, 13G can be formed by changing the separation distance of the two cover members 35 in steps, respectively.

The support member 34 may be fixed, and the shearing device 24 may move in the direction of approaching or separating from the support member 34.
The cover member 35 is not limited to a resin material.

The cover member 35 is not limited to a planar sheet-like member, and may be a box-like member such as the covering member 40, for example.
After forming the brush portions 13B, 13G, and 13J by cutting the entire tip of the brush portion 13C without using the cover member 35, the brush portions 13A, 13D, 13B, 13D, 13B, 13B, 13B, 13B, 13B, 13B, and 13B having short hairs are further formed using the cover member 35. 13F, 13H, and 13I may be formed.

The shearing device 24 and the cutting position adjusting device 25 may constitute a roll brush manufacturing device.
The step of the roll brush 11 may be asymmetrical along the direction of the axis S1.
