It is AA sectional drawing. In addition, the same code | symbol shown in the figure has shown the same thing.

  1 to 3, a second clamping mechanism 20 that clamps one end of a metal wire 50 as a core wire of the twisting brush 53 is provided on one end side of the work table 2 of the twisting brush manufacturing apparatus 1. The base 4a of the wire support mechanism 4 is fixed so that the mounting position can be adjusted by rotating the lever 3. Further, the speed reducer 5a of the first wire support mechanism 5 provided with the first clamping mechanism 10 for clamping the other end of the metal wire 50 is fixed to the other end side of the work table 2, and the work table is fixed. On 2, a wire support mechanism 4 and a wire support mechanism 5 are arranged side by side.

  The wire support mechanism 4 includes a base 4a provided with a square cylindrical case portion 4b at the top, and a cylinder shaft 6 provided so as to be movable in the axial direction through the left and right sides of the case portion 4b above the base 4a. And a guide shaft 7 and a clamping mechanism anterior surface clamping portion 21a which is provided at one end of the cylinder shaft 6 on the side of the speed reducer 5a and includes a pair of clamping members 23 and 24 which face each other and approach and separate from each other. .

  The wire rod support mechanism 5 includes a speed reducer 5a as a driving device and a pinching mechanism 10 that is attached to an output shaft 5b of the speed reducer 5a and includes a pair of pinching members 13 and 14 that face each other and are separated from each other. It is configured. The rotating shaft 10a of the clamping mechanism 10 extends to the rear end side of the clamping member 13, and is directly connected to the output shaft 5b of the speed reducer 5a and attached coaxially. As will be described later, the speed reducer 5a is a clutch motor 60 that applies rotational power to the speed reducer 5a to cause the speed reducer 5a to function as a drive device, a power transmission mechanism 40 of the clutch motor 60, and a link that adjusts the power transmission state of the clutch motor 60. A mechanism 65, a pedal 67 for operating the link mechanism 65, and the like are attached, and the speed reducer 5a is configured to be rotatable and decelerable. In the embodiment, the clutch motor 60 and the speed reducer 5a are used as the rotating device. However, the electric motor may be used so as to perform speed control.

  Further, the clamping mechanism 10 and the clamping mechanism 20 have clamping parts 11 and 21 that clamp the respective ends of the metal wire 50 on the front surfaces 12 and 22, and the metal wire that is clamped by the both clamping mechanisms 10 and 20. The two front surfaces 12 and 22 are spaced apart from each other at positions corresponding to both end portions 50.

Then, a plurality of short brush hairs 51 are mounted orthogonally between the metal wire rods 50 and 50 to rotate the clamping mechanism 10, and the plurality of metal wire rods 50 are twisted by the rotation so that the brush hairs 51 are metalized. The twisting brush 53 can be manufactured by being fixed to the wire 50 and spirally arranged.

  The guide shaft 7 is connected to the cylinder shaft 6 at one end on the speed reducer 5a side protruding from the base 4a. In a square cylindrical case portion 4b provided on the upper portion of the base 4a, a flange member 6b is attached to the middle of the cylinder shaft 6 penetrating to the left and right of the case portion 4b. The flange member 6b is provided with a cross shaft 6c projecting perpendicularly to the cylinder shaft 6, and a rotation-preventing roller 6d is pivotally supported on the cross shaft 6c. In addition, a guide rail 4c is provided on the inner side wall of the case portion 4b so that the upper surface of the roller 6d contacts and is guided in parallel to the cylinder shaft 6. The roller 6d is guided to the lower surface of the guide rail 4c. Configured to move. Therefore, the flange member 6b, the roller 6d, and the guide rail 4c function as a detent when the cylinder shaft 6 moves.

  The guide shaft 7 is attached with a coil spring 8 fitted to the other end protruding from the base 4a. Since one end of the guide shaft 7 is connected to the cylinder shaft 6, the guide shaft 7 moves in parallel with the cylinder shaft 6. Further, the guide shaft 7 normally biases the clamping mechanism 20 attached to one end of the cylinder shaft 6 by a coil spring 8 in a direction away from the clamping mechanism 10, and is set to the initial position shown in FIG. At the same time, the state of being able to return to the initial position is maintained and the movement of the clamping mechanism 20 in the direction of the clamping mechanism 10 is restricted.

  A bracket 9 is fixed to the upper part of the base 4a. The bracket 9 is provided with a fixed shaft 9a projecting, and an operation shaft 6a projecting from one end of the cylinder shaft 6 projecting from the base 4a toward the speed reducer 5a. A lever 30 is attached to the fixed shaft 9a so as to be rotatable about the fixed shaft 9a. The lever 30 is provided with a long hole 31 at the center, and an operation shaft 6a protruding from the upper part of the cylinder shaft 6 is loosely fitted to an operation portion provided on the side opposite to the fixed shaft 9a as a fulcrum. It is possible to adjust the proximity / separation state of the clamping mechanism 20 with respect to the clamping mechanism 10 by manually operating the cylinder 32 to move the cylinder shaft 6 or restrict the movement of the cylinder shaft 6.

  The power transmission mechanism 40 includes a pulley 42 coaxially fixed to an input shaft 41 and a pulley 44 coaxially fixed to an output shaft 43 connected by a belt 45. The input shaft 41 of the power transmission mechanism 40 is a clutch motor. The output shaft 61 of 60 is fixed coaxially. The output shaft 43 of the power transmission mechanism 40 is fixed coaxially to the input shaft 5c of the speed reducer 5a.

  The operation arm 62 of the clutch motor 60 and the long and short shafts 63 and 64 constitute a link mechanism 65, and a pedal 67 is pivotally supported on the drive shaft 66 of the shaft 64. By operating the pedal 67 to set the rotation angle of the drive shaft 66, the link mechanism 65 is controlled, and the input shaft 41 of the power transmission mechanism 40 and the output shaft 61 (not shown) of the clutch motor 60 are controlled by a clutch mechanism (not shown). Can be set to be connected or blocked. As described above, the clutch mechanism is controlled by operating the pedal 67 to adjust the power transmission state of the clutch motor 60. Therefore, when the input shaft 41 of the power transmission mechanism 40 and the output shaft of the clutch motor 60 are connected, the power transmission is performed. The rotation state of the output shaft 43 of the mechanism 40 can be adjusted to adjust the rotation state of the speed reducer 5a. Therefore, the operation of the pedal 67 can stop the rotation of the clamping mechanism 10 attached to the output shaft 5b of the speed reducer 5a or adjust the rotation speed.

  Next, the structures of the clamping mechanism 10 and the clamping mechanism 20 will be described with reference to FIGS. 4 (a) and 4 (b) and FIGS. 5 (a) and 5 (b). 4A is a sectional view of the clamping mechanism, FIG. 4B is an exploded perspective view of the clamping mechanism, FIG. 5A is a front view of the clamping mechanism, and FIG. 5B is a front view of the clamping mechanism. .

  The sandwiching mechanism 10 includes first and second sandwiching members 13 and 14 that face each other and approach and separate from each other. The first clamping member 13 has an L-shaped outer shape with a rotating shaft 10a extending at the rear in the longitudinal direction, and the second clamping member 14 has a rectangular parallelepiped shape.

  A groove member 15 a having an engaging recess 11 b is provided on the front side of the upper portion of the clamping member 13. Further, on the back side of the bottom of the sandwiching member 13, a U-shaped wall portion 13 a in which three side walls are continuous in a U-shape is provided. In the U-shaped wall portion 13a, opposed wall surfaces 13b and 13b are provided with holes 13c and 13c.

  In addition, a convex member 15b having an engaging convex portion 11a fitted to the engaging concave portion 11b is provided at the front portion of the clamping member 14. On the back side of the clamping member 14, a protruding piece 14 a that fits into the groove 13 d formed by the U-shaped wall portion 13 a of the clamping member 13 extends, and the protruding piece 14 a has a horizontal hole that intersects the protruding direction. 14b is provided.

  Then, the projecting piece 14a of the clamping member 14 is fitted into the groove 13d of the clamping member 13, the shaft member 16 is fitted in the order of the holes 13b, 14b, 13b, and the clamping member 13 and the clamping member 14 are connected at the rear end. The engaging convex part 11a and the engaging concave part 11b are assembled so as to be openable and closable by pivoting.

  Further, the sandwiching member 13 and the sandwiching member 14 are vertically provided with holes 13e, 14e. A bolt 17 is inserted from below the hole 13e, and the shaft 17a of the bolt 17 protruding from above the hole 13e is provided. The coil spring 17b is loosely fitted, and in this state, the nut 17c is attached to the tip of the shaft 17a that is inserted into the hole 14e and protrudes from the hole 14e, and the assembly of the clamping mechanism 10 is completed.

  Thus, the clamping mechanism 10 applies the elastic force in the direction in which the coil springs 17b are separated between the hole 13e of the clamping member 13 and the hole 14e of the clamping member 14 and the one ends thereof are separated from each other. By attaching the nut 17c through the coil spring 17b and the hole 14e, the clamping member 13 and the clamping member 14 are connected by a coupling member made up of the bolt 17 and the nut 17c, and the other end in the direction of opening and closing each one end side. The shaft member 16 is pivotally supported on the side so as to be rotatable about the shaft member 16. The clamping mechanism 10 tightens the nut 17c so that the clamping member 13 and the clamping member 14 rotate about the shaft member 16, and the clamping recess 11b is opened and closed by opening and closing the engagement recess 11b and the engagement protrusion 11a. The tightening state is adjusted.

  The structure of the clamping mechanism 20 is different from the clamping mechanism 10 as shown in FIGS. 5A and 5B, but the other structure is substantially the same as that of the clamping mechanism 10 here. Then, it explains briefly.

  The clamping mechanism 20 spans the coil spring 17b between the hole 23e of the clamping member 23 and the hole 24e of the clamping member 24, and gives an elastic force in a direction in which the one end sides are separated from each other, and the bolt 17 has the hole 23e and the coil spring 17b. , Through the hole 24e and attaching the nut 17c, the holding member 23 and the holding member 24 are pivotally supported around the shaft member 16 on the other end side in the direction of opening and closing each one end side. Then, the clamping mechanism 20 clamps the nut 17c so that the clamping member 23 and the clamping member 24 rotate around the shaft member 16, and the dorsal surface is clamped such as a twill pattern or a mesh pattern. The tightening state of the clamping part 21 by opening and closing the parts 21a and 21b is adjusted.

  As shown in FIGS. 1 and 2, the nut 17c is provided with a cylindrical spanner 29 having an operation handle 29a, and the nut 17c can be operated by rotating the operation handle 29a. The clamping mechanism 20 tightens the nut 17c by rotating the operation handle 29a of the cylindrical spanner 29, whereby the clamping member 23 and the clamping member 24 rotate about the shaft member 16, and the clamping part 21 is tightened. Can be adjusted.

  The structures of the clamping mechanism 10 and the clamping mechanism 20 described above are different because the clamping part 11 of the clamping mechanism 10 is formed by bundling a plurality of metal wires in an annular shape, so that the engaging convex part 11a The engaged state with the engaging recess 11b is formed so as to be deeply engaged vertically. In addition, the pinching portion 21 of the pinching mechanism 20 is used to twist a metal wire rod in a state where a plurality of metal wire rods are arranged side by side and the metal wire rods are sandwiched side by side when the twisting brush is manufactured. In some cases, since the vertical height of the clamping part 21 is equivalent to one metal wire, a large number of metal wire materials are held side by side by the pressure contact of the dorsal surface clamping parts 21a and 21b. In addition, it is good for the contact surface of the engaging convex part 11b of the above-mentioned clamping mechanism 10 to carry out slip-fastening processes, such as a twill pattern and a mesh pattern.

  Next, the operation of the twisting brush manufacturing apparatus 1 will be described with reference to FIGS. As shown in FIG. 6A, the two metal wires 50 are bundled and inserted from the front surface 12 into the clamping part 11 of the clamping mechanism 10, and the nut 17c of the clamping mechanism 10 is tightened, whereby the clamping state of the clamping part 11 is changed. One end of the two metal wires 50 is locked to the holding part 11 by adjusting.

  Thereafter, the cylinder shaft 6 is moved so as to bring the clamping mechanism 20 closer to the clamping mechanism 10 by operating the operating portion 32 of the lever 30. Then, the other ends of the two metal wires 50 are inserted from the front surface 22 into the clamping portion 21 of the clamping mechanism 20, and the nut 17 c is tightened by rotating the operation handle 29 a of the cylindrical spanner 29. The other end of the two metal wires 50 is locked to the holding part 21 by adjusting the tightening state.

  In this way, the two metal wire rods 50 are arranged between the wire rod support mechanism 4 and the wire rod support mechanism 5, and the respective end portions are clamped to the clamping mechanism 10 and the clamping mechanism 20. Then, a large number of short brush hairs 51 are inserted between the two metal wire rods 50, and a plurality of short brush hairs 51 are mounted orthogonally between the two metal wire rods 50. By operation, the clamping mechanism 10 attached to the output shaft 5b of the speed reducer 5a is rotated.

  While the pinching mechanism 10 rotates about the pinching portion 11 and twists the two metal wires 50, the brush bristles 51 are fixed between the two metal wires 50 and arranged in a spiral shape. When the pinching mechanism 20 is shortened by twisting and the pinching mechanism 20 tries to move toward the pinching mechanism 10, the operation unit 32 of the lever 30 is operated so that no twisting unevenness is generated between the two metal wires 50 to be twisted. Thus, the twisting state between the two metal wires 50 is adjusted by adjusting the proximity of the holding mechanism 20 to and away from the holding mechanism 10 and finely adjusting the tension of the metal wire 50. In this way, while rotating the pinching mechanism 10 to finely adjust the tension of the metal wire 50, the brush wire 51 is pinched and fixed to the metal wire 50 by twisting the metal wire 50, and the twist as shown in FIG. A brush 53 is formed.

  As described above, the twisted brush manufacturing apparatus 1 holds one end of the bundled metal wire 50 to the holding portion 11 of the holding mechanism 10 and holds the other end of the metal wire 50 to the holding portion 21 of the holding mechanism 20. By driving the speed reducer 5a by operating the pedal 67, in addition to the twisting brush 53, various types of metal wires can be changed, and the arrangement of the bristle between the metal wires can be changed. A twist brush can be manufactured.

  For example, as described above, the twisted brush manufacturing apparatus 1 is used to form a plurality of short brush hairs 51 between the upper two and the lower two of the four metal wires 50 as shown in FIG. The brush bristles 51 are fixed to the metal wire 50 by twisting the metal wire 50 and are arranged in a spiral manner to form the twist brush 53. ) Between the upper one and the middle two of the four metal wires 50 and between the two middle and the lower one of the metal wires 50, the brush bristles 51 are orthogonal to the metal wires 50 in the same direction. The bristles 51 are fixed to the metal wire 50 by twisting the metal wire 50 and arranged in a spiral shape to form the twist brush 53.

  The present invention is not limited to the above-described embodiment, and can be implemented in any way as long as the configuration described in the claims is not changed.
