Definitions
- This invention relates to a brush, a bristle setting apparatus therefor and a bristle setting method therefor, and more particularly to a brush having bristle tufts set thereon by means of small metal pieces called anchors, and a bristle setting apparatus therefor and a bristle setting apparatus therefor.
- the bristle setting apparatus generally includes a bristle tuft feed mechanism 84, an auxiliary guide 88, a bristle setting needle 83, a bristle setting guide 92, a bristle cutting mechanism 94 and an anchor feed mechanism 96.
- the bristle tuft feed mechanism 84 is constructed so as to intermittently feed bristle tufts 81 each formed by bundling a predetermined number of continuous bristles such as continuous nylon monofilaments together by a predetermined length for every intermittent feeding during upward movement of a bristle setting needle 83 of a bristle setting mechanism 82.
- the auxiliary guide 88 is arranged above a front side of the bristle tuft feed mechanism 84 and includes a presser section 85 provided on a lower surface thereof so as to press the bristle tufts.
- the auxiliary guide 88 is formed therein with a needle insertion hole 86 vertically extending therethrough perpendicularly to the presser section 85 and an anchor insertion hole 87 extending therethrough to the needle insertion hole 86.
- the bristle setting needle 83 is arranged so as to vertically slide in the needle insertion hole 86.
- the bristle setting guide 92 is positioned below the auxiliary guide 88 so as to be vertically movable and formed with a needle guide hole 90 so as to vertically extend therethrough and be aligned with an extension line of the needle insertion hole 86.
- the bristle setting guide 92 is formed on an upper surface thereof with a bristle tuft receiving recess 91, which functions to interposedly hold the bristle tuft 81 in cooperation with the presser section 85 when the bristle setting guide is raised.
- the bristle tuft cutting mechanism 94 is positioned between the bristle tuft feed mechanism 84 and the bristle setting guide 92 and in proximity to the bristle tuft 81 and includes a rotary cutter 93 for cutting the bristle tuft 81 into a predetermined length when the bristle setting guide 92 is raised.
- the anchor feed mechanism 96 is arranged so as to feed an anchor 95 into the anchor insertion hole 87 of the auxiliary guide 88.
- the bristle tuft feed mechanism 84 is driven to feed the bristle tuft of a continuous length toward the bristle tuft receiving recess 91, to thereby abut the bristle tuft 81 against a stopper 97.
- the anchor feed mechanism 96 is driven to feed the anchor of a sheet-like shape into the anchor insertion hole 87 of the auxiliary guide 88.
- the bristle tuft 81 thus fed into the bristle tuft receiving recess 91 is interposedly held by the presser section 85 at a distal end of the auxiliary guide 88 and then the bristle tuft 81 thus held is cut into a predetermined size by means of the rotary cutter 93 of the bristle tuft cutting mechanism 94. Thereafter, the bristle setting mechanism 82 and auxiliary guide 88 are downwardly moved together toward the toothbrush handle 1.
- the bristle setting needle 83 is downwardly moved through the needle insertion hole 86 and needle guide hole 90. This permits a tip end of the bristle setting needle 83 to cut the anchor 95 into a predetermined length and force out the anchor 95 thus cut.
- the anchor 95 thus cut forces the bristle tuft 81 cut into the predetermined length into the needle guide hole 90 while folding it into two parts in the middle thereof or bending it into a U-shape.
- the bristle setting needle 83 is permitted to outwardly project at a distal end thereof from the needle guide hole 90 at the time when the bristle setting mechanism 82 is approached at a distal end thereof to the bristle set surface 3 of the head 2 of the toothbrush handle 1 to the utmost, so that the bristle tuft 81 cut into the predetermined length is driven into each of bristle set holes 4 formed on the bristle set surface 3 while being kept folded in two by means of the anchor 95, resulting in bristle setting being accomplished as shown in Figs. 15A and 15B.
- an angle ⁇ at which the anchor 95 is driven into the bristle setting hole 4 (hereinafter referred to as “anchor driven angle ⁇ ") is kept constant at, for example, 12 degrees.
- anchor driven angle ⁇ an angle at which the anchor 95 is driven into the bristle setting hole 4
- the prior art fails to vary the anchor driven angle for every bristle setting hole 4 as desired. This possibly causes the anchors 95 set in the bristle set holes 4 adjacent to each other to be abutted against or contacted with each other when a distance or interval between the bristle set holes 4 is excessively decreased.
- anchor driven angle ⁇ indicates an angle between a longitudinal direction of the anchor and a predetermined direction of the brush head such as, for example, a longitudinal direction of the brush head.
- the anchor driven angle ⁇ is fixed, therefore, arrangement of setting of the bristle tufts is limited to a pattern which prevents interference between the anchors adjacent to each other, such as a linear arrangement pattern, a lattice arrangement pattern or the like, so that the prior art fails to realize any other arrangement pattern such as a circular pattern in which bristle tufts are arranged in a circular manner as a whole, a curved pattern in which bristle tufts are arranged in conformity to any desired curve or the like.
- the conventional bristle setting apparatus substantially fails to provide a toothbrush of the anchor type in which bristles are arranged in any desired directions so as to be commonly accommodated to a brushing site in the mouth cavity and a manner of brushing as in a toothbrush produced by in-mold techniques or thermal fusion bonding.
- the bristle setting guide 92 for driving the anchor 95 into the bristle set hole 4, as shown in Fig. 17, is generally provided on a side of a distal end thereof with a bristle tuft separating unit 99 for reciprocating a bristle tuft separating plate 98 while pivotally moving it in synchronism with bristle setting operation of the bristle setting guide 92, although such construction is not shown in Figs. 13 and 14.
- the bristle tuft separating unit 99 functions to hold down, during setting of a bristle tuft 81 in the bristle set hole 4, an already-set bristle tuft 81 adjacent thereto to keep it away from a path of movement of the bristle setting guide 92, resulting in the already-set bristle tuft being kept out of the setting. This prevents formation of such a connection bristle as indicated by reference numeral 81a in Fig. 18A or such a ring bristle as indicated by 81b in Fig. 18B.
- the bristle tuft separating unit 99 is kept fixed at a predetermined position with respect to the bristle setting mechanism 82, so that a toothbrush handle is merely subject to parallel displacement.
- the bristle tuft separating unit 99 is kept fixed at a predetermined position with respect to the bristle setting mechanism 82, so that a toothbrush handle is merely subject to parallel displacement.
- the conventional bristle setting apparatus still causes a pattern of arrangement of the bristle tufts to be subject to restriction.
- a bristle tuft arrangement pattern obtained by the conventional bristle setting apparatus necessarily causes setting of the bristle tufts to be carried out on a side away from the bristle tuft separating unit 99, leading to possible formation of the connection bristle 81a and/or ring bristle 81b, resulting in the product being often defective.
- the present invention has been made in view of the foregoing disadvantages.
- a brush of the anchor type which is capable of permitting an anchor driven angle to be varied depending on an anchor driven position, to thereby attain bristle setting at an increased packing density and/or in any desired arrangement pattern.
- a brush which has bristle tufts set in bristle set holes formed on a bristle set surface of a head of the brush, each of the bristle tufts being kept folded into two parts with an anchor being interposed between the two parts.
- the brush is characterized in that at least two of a plurality of the anchors are driven into the bristle set holes at anchor driven angles different from each other.
- the head is formed with a plurality of the bristle set holes separated from each other and the bristle set holes each have one of the bristle tufts set therein by means of the anchor.
- at least two of the bristle set holes adjacent to each other are preferably separated from each other by means of a partition wall formed to have a thickness of between 0.1 mm and 3.0 mm.
- the anchor driven angles of the anchors are each preferably so set that an extension line of the anchor defined in a longitudinal direction thereof does not intersect the bristle set hole adjacent thereto.
- the bristle set hole may have a plurality of the bristle tufts set therein by means of the anchors.
- the above-described construction of the present invention permits the anchor driven angle to be varied as desired, to thereby prevent the anchors adjacent to each other from being abutted against each other, resulting in bristle setting at an increased packing density which is never attained in the conventional brush of the anchor type being realized.
- such construction permits the bristle tufts to be arranged in any desired pattern such as a circular pattern wherein the bristle tufts are arranged in a circular array, a curved pattern wherein the bristle tufts are arranged along any desired curve or the like which has been conventionally obtained only by in-mold techniques, thermal fusion bonding or the like.
- a bristle setting apparatus for a brush.
- the bristle setting apparatus is characterized in that the apparatus includes a bristle setting means for setting bristle tufts on a bristle set surface of a head of the brush by means of anchors, a brush holder arranged opposite to the bristle setting means while being spaced therefrom at a predetermined interval and constructed so as to permit the head of the brush to be held at a predetermined position thereon, a position adjusting means for adjusting a position of the brush holder with respect to the bristle setting means, and a brush rotating mechanism for adjusting a rotational inclination angle of the brush holder with respect to the bristle setting means.
- the position adjusting means is moved while being controlled, to thereby vary the position of the brush holder with respect to the bristle setting means and the brush rotating mechanism is rotated while being controlled, to thereby vary the rotational inclination angle of the brush holder with respect to the bristle setting means.
- a bristle setting method for a brush wherein bristle tufts are set on a bristle set surface of a head of the brush by means of anchors, each of the bristle tufts being folded into two, is provided.
- the bristle setting method is characterized in that the method includes the steps of arranging a brush holder so as to be opposite to a bristle setting means of the anchor type after holding the head of the brush to be subjected to bristle setting at a predetermined position on the brush holder and successively setting bristle tufts on the bristle set surface of the head of the brush while varying a position of the brush holder with respect to the bristle setting means and varying a rotational inclination angle of the brush holder with respect to the bristle setting means.
- each of the bristle setting apparatus and bristle setting method permits the anchor driven angle at which the anchor is driven into the bristle set hole to be varied as desired for every bristle set hole, resulting in bristle setting at a high packing density and arranging the bristle tufts in any desired pattern such as a circular pattern, a curved pattern or the like which is never obtained in the conventional brush of the anchor type being realized.
- such construction permits the head of the brush to be rotated over an angle of 360 degrees, resulting in positional relationship between the bristle tuft which has been just subjected to bristle setting and the bristle to be subjected to the next bristle setting operation being kept constant as shown in Fig. 17.
- This permits bristle setting to be started at any desired bristle set hole, to thereby prevent an order of bristle setting from being limited by the bristle tuft arrangement pattern and eliminate formation of a connection bristle and/or a ring bristle due to entangling between the bristle tufts adjacent to each other.
- the construction which permits rotation of the head over 360 degrees leads to bristle setting in a ring-like pattern as shown in each of Figs. 6A, 6B, 7 and 8.
- a bristle setting apparatus according to the present invention is illustrated, which is applied to a bristle setting apparatus for a toothbrush of the anchor type.
- reference numerals like those in the conventional bristle setting apparatus for a toothbrush of the anchor type described above with reference to Figs. 13 and 14 designate like or corresponding parts.
- a bristle tuft separating unit (not shown) incorporated in the illustrated embodiment may be constructed in substantially the same manner as that described above with reference to Fig. 17.
- a bristle setting apparatus of the illustrated embodiment generally includes a bristle setting mechanism (bristle setting means) 82 which is so constructed that a bristle tuft bent or folded in two is knocked out by an anchor 95 (Figs. 5A to 12B) to carry out bristle setting in substantially the same manner as the conventional bristle setting apparatus for a toothbrush of the anchor type, an X-Y-Z table mechanism 11 arranged opposite to the bristle setting mechanism 82 so as to be movable in X-axis, Y-axis and Z-axis directions, resulting in it being positionally adjustable in the directions, and a brush rotating mechanism 12 rotatably arranged on the X-Y-Z table mechanism 11.
- a bristle setting mechanism bristle setting means
- the bristle setting mechanism 82 is constructed in substantially same manner as that incorporated in the conventional bristle setting apparatus described above with reference to Figs. 13 and 14. Thus, it is constructed so as to reciprocate along a central line O-O of a needle guide hole to knock out a bristle tuft 81 folded into two by the anchor by means of a brief setting needle and set it in each of bristle set holes 4 of a bristle set surface 3 of a head 2 of a toothbrush handle 1 clamped or gripped by a handle holder 16 described hereinafter.
- the X-Y-Z table mechanism 11 is constituted by a combination of an X-axis table 11a arranged so as to be reciprocated in a lateral direction, a Y-axis table 11b arranged so as to be reciprocated in a vertical direction and a Z-axis table 11c arranged so as to be reciprocated in a longitudinal direction, which are positionally adjusted by driving and controlling an X-axis servomotor 13a, a Y-axis servomotor 13b and a Z-axis servomotor 13c through a table servodriver 14, respectively.
- the brush rotating mechanism 12 includes a brush holder 16 arranged so as to be rotatable in both normal and reverse directions through a rotation shaft 15 fixed on a rear surface of the brush holder 16, a rotation servomotor 17, a rotation servodriver 18 for driving and controlling the rotation servomotor 17, and a combination of gears 20 and 21 and a drive belt 22 arranged so as to operatively connecting the rotation shaft 15 of the brush holder 16 and a revolving shaft 19 of the servomotor 17 to each other therethrough.
- the brush holder 16 acts as a clamp or grip mechanism for holding the toothbrush handle 1 at a predetermined position while clamping the head 2 of the toothbrush which is inserted thereinto.
- the brush holder 16 may be provided at four corners thereof with pawls 23a to 23d, so that the head 2 of the toothbrush 1 is inserted into a space defined by the pawls 23a to 23d, resulting in the whole toothbrush handle 1 being held at the predetermined position while being clamped by the pawls 23a to 23d.
- the brush rotating mechanism 12 equipped with the brush holder 16 thus constructed is securely mounted on the X-Y-Z table 11 by means of a mounting member 24, so that movement and control of the X-Y-Z table 11 may permit a position of the brush holder 16 in each of the X-axis, Y-axis and Z-axis directions to be varied as desired.
- rotation of the brush holder 16 by means of the rotation servomotor 17 permits a direction of the toothbrush handle 1 clampedly held on the brush holder 16 or a rotational inclination angle ⁇ of the handle 1 to be varied as desired as shown in Fig. 4.
- Fig. 4 shows a representative or typical example of setting of the rotational inclination angle.
- any desired intermediate angle may be suitably set or selected.
- reference numeral 25 designates a control section for controlling operation of the whole apparatus including the table servodriver 14, rotation servodriver 18 and bristle setting mechanism 82.
- the control section 25 may be constituted by, for example, a combination of a personal computer and a PC (sequencer).
- the toothbrush handle 1 to be subjected to bristle setting is inserted into the space defined by the pawls 23a to 23d of the brush holder 16 manually or by means of any suitable automatic loading machine while keeping the bristle set surface 3 of the toothbrush handle 1 facing outside, to thereby clampedly hold the whole toothbrush handle 1 on the handle holder 16.
- the control section 25 controls the table servo driver 14, to thereby drive the X-axis servomotor 13a, Y-axis servomotor 13b and Z-axis servomotor 13c, resulting in a position of the brush holder 16 in each of the X-axis direction, Y-axis direction and Z-axis direction being adjusted so that a position of a first bristle set hole 4 to be subjected to bristle setting may be aligned with the central axis O-O of the needle guide hole 90 (see Figs. 13 and 14) of the bristle setting mechanism 82.
- control section 25 controls the rotation servodriver 18 to drive the rotation servomotor 17, to thereby adjust a rotation angle of the toothbrush handle 1 clampedly held on the brush holder 16 so that the toothbrush handle 1 may have an indicated inclination angle.
- the control section 25 controls the bristle setting mechanism 82 so that the bristle setting mechanism 82 may knock out the bristle tuft 81 while folding it into two by means of the anchor 95 to set it in the bristle set hole 4 on the bristle setting surface 3.
- Rotation of the toothbrush handle 1 permits positional relationship between the bristle tuft 81 which has been just subjected to bristle setting and the next bristle set hole 4 to be subsequently subjected to bristle setting to be kept constant as shown in Fig. 17.
- the illustrated embodiment permits bristle setting to be started at any desired bristle set hole 4, to thereby eliminate the disadvantage of the prior art that an order of bristle setting is restricted by a pattern of arrangement of the bristle tufts.
- the illustrated embodiment fully prevents formation of the connection bristle 81a and/or ring bristle 81b shown in Figs. 18A and 18B, to thereby minimize defectives.
- Figs. 6A to 6D each show a pattern of arrangement of the bristle tufts which may be obtained by the bristle setting apparatus of the illustrated embodiment by way of example.
- the bristle set holes 4 of a rectangular shape adjacent to each other are positioned in proximity to each other, to thereby be densely arranged while being spaced from each other through a thin partition wall.
- Fig. 6A shows a circular arrangement pattern obtained by arranging the bristle set holes 4 of a rectangular shape in a ring-like array.
- Fig. 6B shows a U-shaped arrangement pattern obtained by arranging the rectangular bristle set holes 4 in a U-shaped array.
- FIG. 6C shows a Y-shaped arrangement pattern obtained by arranging the rectangular bristle set holes 4 in a Y-shaped array.
- Fig. 6D shows a windmill-like arrangement pattern obtained by arranging the rectangular bristle set holes 4 in a windmill-like array.
- the arrangement patterns each permit an anchor driven angle at which the anchor 95 is driven into the bristle set hole 4 to be varied, to thereby prevent the anchors 95 adjacent to each other from being contacted with or abutted against each other, resulting in that bristle setting can be attained in any desired arrangement pattern.
- the bristle set holes 4 are arranged in proximity to each other through the partition wall decreased in thickness, to thereby prevent formation of a gap between the bristle tufts in the bristle set holes 4, so that bristle setting may be attained at a highly increased packing density.
- a toothbrush having bristle tufts set thereon by the bristle setting apparatus of the illustrated embodiment will be described with reference to Figs. 7 to 10.
- the illustrated embodiment provides a toothbrush of the anchor type having bristles arranged in a variety of desired directions thereon so as to be commonly accommodated to a brushing site in the mouth cavity and a manner of the brushing.
- driving of the anchor 95 into the bristle set hole 4 concerned is desirably carried out within an angle range which prevents an extension P-P of the anchor 95 defined in a longitudinal direction thereof from intersecting the bristle set holes 4 adjacent to the concerned bristle set hole 4, as shown in Figs. 11A and 11B.
- Driving of the anchor 95 within such an angle range prevents any crack from occurring between the concerned bristle set hole 4 and any bristle set hole 4 adjacent thereto. Also, it prevents whitening of resin of which the head of the toothbrush handle is made.
- the partition wall through which the bristle set holes 4 adjacent to each other are isolated from each other is desirably formed to have a thickness d between 0.1 mm to 3.0 mm.
- the bristle set holes 4 adjacent to each other are isolated from each other through the partition wall, resulting in the bristle set holes being arranged independently from each other.
- the bristle set holes 4 thus arranged each have the single bristle tuft 81 set therein by means of the single anchor 95.
- bristle setting is not limited to such a way.
- the bristle set holes 4, as shown in Figs. 12A and 12B each may be formed to have an elongated configuration of which a length corresponds to a sum of lengths of a plurality of the bristle set holes 4 each shown in Fig. 11A or 11B.
- a plurality of the bristle tufts 81 are set one by one in a manner to adjoin each other by means of a plurality of the anchors 95.
- Bristle setting in such a manner possibly causes the bristle tuft 81 now set in the elongated bristle set hole 4 to tilt into a space defined on a side on which the next bristle setting is to be carried out, to thereby interfere with the next bristle setting operation.
- such a problem may be effectively solved by carrying out the next bristle setting while holding down the just set bristle tuft in an opposite direction by means of such a bristle tuft separating unit as indicated by reference numeral 99 in Fig. 17.
- Bristle setting in such a manner as shown in Figs. 12A and 12B keeps the bristle tufts adjacent to each other from being separated from each other through such a partition wall as described above, to thereby permit formation of a long bristle tuft chain which is rendered fully continuous as seen in a toothbrush made by in-mold techniques or thermal fusion bonding.
- the brush holder 16 is rotated through a combination of the rotation servomotor 17, gears 20 and 21, and drive belt 22.
- the brush holder 16 may be connected directly to the servomotor 17 or rotated by any other suitable rotation means.
- the head 2 of the toothbrush handle 1 is clampedly held by the pawls 23a to 23d formed on the four corners of the brush holder 16.
- any other suitable clamp mechanism may be used for this purpose, so long as it effectively clamps the head 2 of the toothbrush handle 1.
- the illustrated embodiment is so constructed that the X-Y-Z table mechanism 11 is driven by means of the three servomotors 13a to 13c.
- any other suitable drive mechanism such as, for example, a linear slider or the like may be substituted for the servomotor to this end.
- the handle rotating mechanism 12 on which the brush holder 16 is mounted is rotatably mounted on the X-Y-Z table mechanism 11.
- the illustrated embodiment may be constructed in a contrary manner. More specifically, the brush holder 16 may be fixedly mounted on the X-Y-Z table mechanism 11, which may be then mounted on the revolving shaft of the brush rotating mechanism so as to be movable in the X-axis, Y-axis and Z-axis directions.
- the illustrated embodiment includes the X-Y-Z table mechanism 11 which permits positional control in the X-axis, Y-axis and Z-axis directions.
- the bristle set surface 3 of the toothbrush handle 1 is formed to be even or flat, positional control in the Z-axis direction may be eliminated.
- an X-Y table mechanism may be substituted for the X-Y-Z table mechanism 11.
- the brush according to the present invention is so constructed that at least two of the anchors are driven into the respective bristle set holes at anchor driven angles different from each other.
- Such construction permits bristle setting to be carried out at a high packing density which is never obtained in the conventional brush of the anchor type made by keeping the anchor driven angle fixed.
- Such construction realizes bristle setting in any desired arrangement pattern such as, for example, a circular pattern in which the bristle tufts are arranged in a circular array, a curved pattern in which the bristle tufts are arranged along any desired curve or the like.
- Such an arrangement pattern is conventionally obtained by only in-mold techniques, thermal fusion bonding or the like.
- the brush of the present invention can be commonly accommodated to an object of brushing and a manner of the brushing.
- the bristle setting apparatus and bristle setting method of the present invention are each so constructed that the position adjusting means is moved while being controlled, to thereby vary a position of the brush holder relative to the bristle setting means as desired and the brush rotating mechanism is rotated while being controlled, to thereby set the bristle tuft in the intended bristle set hole of the head of the toothbrush while varying a rotational inclination angle of the brush holder relative to the bristle setting means.
- Such construction permits the anchor driven angle with respect to the bristle set hole to be varied as desired for every bristle set hole, to thereby realize bristle setting at a high packing density and attain bristle setting in any desired bristle tuft arrangement pattern such as a circular arrangement pattern, a curved arrangement pattern or the like which is never attained by the conventional brush of the anchor type and in any order.
- Such construction permits bristle setting to be started at any desired bristle set hole irrespective of the bristle tuft arrangement pattern, to thereby eliminate the disadvantage of the prior art that an order of bristle setting is limited by the bristle tuft arrangement pattern and prevent formation of a connection bristle and/or a ring bristle due to entangling between bristle tufts adjacent to each other.
- the present invention may be applied to not only such a toothbrush as described above but other brushes such as a hair brush, a dressing brush, a cleaning brush and the like so long as they have bristles set thereon by means of anchors. Also, the present invention is applicable to a brush free from a handle or grip.
