Description Hair knitting machine Technical field

The present invention relates to a hair knitting machine for twisting a bundle of hair or knitting a twisted bundle of hair. Background art

Conventionally, the work of twisting a bundle of hair or knitting a twisted bundle of hair for perming or setting is performed manually. Also, during the work, specially designed hair clamps are used or humans hold them by hand to prevent the twisted or braided hair bundles from returning due to the rebound of hair.

However, the manual work of twisting and knitting the hair bundles takes a long time, and it is easy for individual differences in the quality of appearance. Also, during work, there was a problem that the hair bundle was twisted due to the hair rebound losing the rebound of the hair or inadvertently releasing the hand.

An object of the present invention is to provide a hair knitting machine capable of twisting a hair bundle or knitting a twisted hair bundle in a short time without skill.

And housing rotation means that abuts or engages with the shaft.

According to the present invention, when the drive shaft rotates the drive shaft in a state where the rotation of the housing is prevented by engaging the brake with the housing by operating the switch, the clip The rotating shaft rotates. Thereby, each bristle bundle sandwiched between the clips can be twisted around each clip rotation axis as a central axis. When the drive shaft is rotated by the drive unit in a state in which the brake is disengaged from the housing by operating the switch, the housing rotates together with the drive shaft by the housing rotation unit. I do. Thereby, each bristle bundle sandwiched between the clips can be twisted around the rotation axis of the housing as a center axis.

Therefore, the switch bundle is firstly operated so that the brake is engaged with the housing, and the switch is twisted about the rotation axis of each clip, and then the switch is released so as to release the engagement of the brake.

A shaft 10 fixed to the case 2 is inserted into a cylindrical bearing 9 provided at the center of a top plate 8 that can be fixed to the housing 3.

In the housing 3, two clip rotating shafts 11 and 11 are rotatably held at symmetric positions about the shaft 10 as a central axis. The clip mounting portions 4 and 4 are fixed to the ends of the clip rotation shafts 11 and 11 respectively, and the clip mounting portions 4 and 4 are rotatably held by a top plate 8 fixed to the housing 3. I have. Outside the case 2, the clips 5, 5 for holding the hair are detachably attached to the clip mounting portions 4, 4 by screws or the like.

A main gear 12 having a cylindrical bearing 13 penetrated by a shaft 10 is provided inside the housing 3, and the main gear 12 is rotatably held by a shaft 10. . Below the main gear 12, a cylindrical drive shaft 14 coaxial with the main gear 12 is provided integrally with the main gear 12. The sub-gears 15 and 15 which are combined with the main gear 12 are fixed to the clip rotation shafts 11 and 11 respectively. The rotation of the drive shaft 14 and the rotation of the clip rotation shafts 11 and 11 can be transmitted to each other via the main gear 12 and the sub-gears 15 and 15.

On one side of the case 2, there is provided a drive lever 6 having a rack 16 which is movable in and out of the case 2 in a linear direction orthogonal to the shaft 10. The drive lever 6 is provided with a spring 17 having one end fixed to the shaft 10 .The spring 17 drives the rack 16 to return to the initial position where the rack 16 comes into contact with the stopper 18 provided in the case 2. Lever 6 is urged out of case 2.

On the shaft 10, a pinion 19 mating with the rack 16 is rotatably held by penetrating the shaft 10, and the pinion 19 is The linear motion is changed to a rotary motion coaxial with the drive shaft 14. That is, in FIG. 3, when the rack 16 moves in the direction of moving into the case 2 (to the right in FIG. 3), the pinion 19 rotates clockwise, and the rack 16 moves away from the case 2 outside. (Figure 3, left), the pinion 19 rotates counterclockwise.

A ratchet 20 that rotates integrally with the pinion 19 is provided above the pinion 19 so as to face the drive shaft 14. As shown in FIG. 3 partially in a perspective view rather than a cross-sectional view, the lower end surface of the drive shaft 14 and the upper end surface of the ratchet 20 facing each other have a large number of triangular-shaped claws 1 which are mutually connected. 4a and 20a are respectively provided around. In the triangular claw 14a of the drive shaft 14, the left side surface 14b is an inclined surface rising leftward and the right side surface 14c is a substantially vertical surface. In addition, each of the claws 20a having a triangular waveform of the ratchet 20 has a substantially vertical surface on the left side surface 20b and a slant surface on the right side that is inclined to the right.

When the rack 16 moves in the direction toward the inside of the case 2 (to the right in Fig. 3) and the pinion 19 and the ratchet 20 rotate clockwise, the claws 20a of the ratchet 20 are substantially perpendicular. The right side surface 20b is engaged with the substantially vertical right side surface 14c of each of the claws 14a of the drive shaft 14 to rotate the drive shaft 14 in the same direction as the ratchet 20, that is, clockwise. On the other hand, when the rack 16 moves in the direction of retreating to the outside of the case 2 (to the left in FIG. 3) and the pinion 19 and the ratchet 20 rotate counterclockwise, the claws 20 a of the ratchet 20 are inclined. Since the right side surface 20 c is not locked to the inclined left side surface 14 b of each claw 14 a of the drive shaft 14, only the ratchet 20 rotates counterclockwise, and the rotation of the ratchet 20 drives. It is not transmitted to shaft 14. As a result, only when the drive lever 16 and the rack 16 move in the direction of moving into the case 2, the drive shaft 14 and the main gear 12 rotate clockwise.

The drive shaft 14 and the main gear 12 rotate in the reverse direction, that is, counterclockwise in FIG. When rotating, the right vertical surface 14 c of each claw 14 a of the drive shaft 14 engages the substantially vertical left surface 20 b of each claw 20 a of the ratchet 20. And try to rotate the ratchet 20 counterclockwise. However, since the spring 17 urges the drive lever 6 and thus the rack 16 toward the outside of the case 2, the rotation of the pinion 19 and the ratchet 20 combined with the rack 16 is locked. The rotation of the ratchet 20 counterclockwise is prevented. As a result, the drive shaft 14 and the main gear 12 are prevented from rotating in the reverse direction.

A spring 22 is wound around the shaft 10, one end of which is locked by a projection 21 provided on the shaft 10, and the other end of which urges the pinion 19 in the axial direction toward the drive shaft 14. ing. The spring 22 urges the pinion 19 and the ratchet 20 toward the drive shaft 14 to strengthen the connection between the ratchet 20 and the drive shaft 14, and moves the rack 16 in the direction in which the rack 16 moves into the case 2. When the ratchet 20 rotates by rotating, the ratchet 20 and the drive shaft 14 are prevented from idling.

At the bottom of the housing 3, two cylindrical hollow portions 23, 23 extend in the radial direction of the housing 3 symmetrically with respect to the center axis of the housing 3. One end of each of the hollow portions 23, 23 opens toward the drive shaft 14, and the other end is closed. The poles 24, 24 are fitted into the hollow portions 23, 23 so as to be able to advance and retreat, respectively, at the opening ends of the hollow portions 23, 23. In the hollow portions 23, 23, springs 25, 25 are provided, which are urged with a predetermined pressure described later so that the pawls 24, 24 are brought into contact with the drive shaft 14. I have.

On the outer peripheral surface of the drive shaft 14, a part of each of the two poles 24, 24 is respectively positioned at a position facing each open end of the two hollow portions 23, 23 of the housing 3. Two concave portions 40, 40 are provided.

The predetermined pressure of the springs 25, 25 causes the rotation of the drive shaft 14 to rotate the drive shaft. Each of the pawls 24, 24 engaged with the respective concave portions 40, 40 of 14 is transmitted to the housing 3 through the hollow portions 23, 23, and the housing 3 is rotatable. When the rotation of the housing 3 is prevented by a brake 28 described later, only the drive shaft 14 passes over the balls 24, 24 with which the recesses 40, 40 of the drive shaft engage. The pressure is set to a level that allows rotation.

On the bottom of the housing 3, cover the periphery of the drive shaft 14,

A cylindrical portion 26 coaxial with the rotation axis of the motor 3 is provided. Also,

As shown in FIG. 3 in a perspective view, not a cross-sectional view, a number of triangular-shaped claws 27 a to be engaged with a brake 28 described later are coaxial with the housing 3 on the lower end surface of the bottom of the base 3. Are provided in an arc shape. In each of the triangular waveform claws 27a, the left side surface 27b is a substantially vertical surface, and the right side surface 27c is a sloped upper right surface.

The brake 28 is formed in a ring shape fitted to the cylindrical portion 26 of the housing 3 so as to be rotatable and slidable in the axial direction. The brake 28 has a large number of triangular-shaped claws 29 a that are engaged with the triangular-shaped claws 27 a when the brake 28 is moved, on a surface facing the housing 3. Each of the claws 29 a having a triangular waveform of the brake 28 has a left side surface 29 b with an inclined surface rising to the left and a right side surface 29 c with a substantially vertical surface. The brake 28 has a switch 7 for operating from outside the case 2 to engage or disengage the pawl 29 a of the brake 28 with the pawl 27 a of the housing 3. It is provided in. When the brake 28 and the switch 7 are at the positions shown in FIG. 3, the engagement between the claws 29 a of the brake 28 and the claws 27 a of the housing 3 is released, and the housing 3 can be rotated. Has become. When the switch 7 is moved in the direction of arrow a in FIG. 2, referring to FIG. 3, the brake 28 and the switch 7 The guide 28 moves diagonally upward, and the pawl 29 a of the brake 28 engages with the pawl 27 a of the housing 3, thereby preventing the housing 3 from rotating. When the brake panel 28 is engaged with or disengaged from the housing 3, the plate panel 41 fixed to the case 2 is provided with respective engaging portions (not shown) provided on the peripheral side surface of the brake 28. To engage and position brake 28.

A spring 30, one end of which is fixed to the bearing 9 of the housing 3, is tightly wound around the bearing 9 of the housing 3 and the bearing 13 of the main gear 12. The other end of the spring 30 urges the main gear 12 and the drive shaft 14 in the axial direction toward the ratchet 20. The spring 30 transmits the rotation of the drive shaft 14 via the main gear 12 and the sub-gears 15 and rotates the clip rotation shaft 11 that rotates in a predetermined direction in a reverse direction due to rebound of hair or the like. When trying to roll, the spring 30 is wound so as to tighten around the drive shaft 14 and prevent reverse rotation of the drive shaft 14.

A spring 31 whose one end is fixed to a brake 28 is closely wound around the cylindrical portion 26 of the housing 3. The other end of the spring 3 1 is in contact with the bottom of the housing 3, and the spring 28 biases the brake 28 in a direction in which the engagement with the housing 3 is released. When the housing 3 tries to rotate in the reverse direction due to the rebound of the hair twisted between the clips 5, the spring 31 tightens around the cylindrical portion 26 to prevent the housing 3 from rotating in the reverse direction. It is wound.

Next, the operation of the present embodiment will be described. Referring to FIG. 2, when the switch 7 is turned in the direction of the arrow a, the brake 28 and the switch 7 shown in FIG. 3 are guided obliquely upward by a guide surface (not shown), and the claws 2 of the brake 28 are moved. 9a is engaged with the pawl 27a of the housing 3, and the rotation of the housing 3 is prevented.

In this state, the drive lever 6 is put in the case When the rack 16 is pushed in, the rack 19 moves into the case 2 and the pinion 19 and the ratchet 20 rotate clockwise, and are driven by the ratchet 20 to drive the drive shaft 14 and the main gear. 1 2 rotates clockwise. Since the rotation of the housing 3 is prevented by the brake 28, the recesses 40, 40 of the drive shaft 14 pass over the pawls 24, 24, and only the drive shaft 14 rotates clockwise. Then, the main gear 12 rotates clockwise together with the drive shaft 14, the sub gears 15 and 15 rotate counterclockwise, and the clip rotating shafts 11 and 11 rotate counterclockwise. As a result, the bristle bundle sandwiched between the clips 5, 5 is twisted counterclockwise.

The drive lever 6 pushed into the case 2 is urged by the spring 17 to return to the initial position. At this time, the pinion 19 and the ratchet 20 rotate counterclockwise due to the movement of the rack 16 to the initial position, but the rotation of the ratchet 20 is not transmitted to the drive shaft 14. Thereafter, when the drive lever 6 is pushed into the case again, the clockwise rotation of the ratchet 20 is transmitted to the drive shaft 14, and the respective clip rotation shafts 11 1 and 11 rotate counterclockwise. In this way, the drive shaft 14 intermittently rotates clockwise only due to the movement of the drive lever 6 into and out of the case 2, and the bristle bundle sandwiched between the clips 5, 5 rotates each clip accordingly. The shaft is intermittently twisted counterclockwise around axes 11 and 11.

Next, when knitting the twisted hair bundles, the switch 7 is turned in the direction b in FIG. At this time, the brake 28 and the switch 7 are guided by a guide surface (not shown) and move diagonally downward, so that the claws 29 a of the brake 28 and the claws 27 a of the housing 3 are engaged as shown in FIG. Is released, and the housing 3 can be rotated.

When the drive lever 6 is pushed into the case 2 in this state, the pinion 19 and the ratchet 20 rotate clockwise due to the movement of the rack 16 into the case 2, and are driven by the ratchet 20. Drive shaft 14 and main gear 1 2 rotates clockwise. Since the engagement between the brake 28 and the housing 3 has been released, the rotation of the drive shaft 14 causes the pawls 24, 24 engaged with the recesses 40, 40 of the drive shaft 14. Then, the power is transmitted to the housing 3 through the hollow portions 23, 23, and the housing 3 rotates clockwise together with the drive shaft 14. At this time, since the main gear 12 rotates in the same direction as the drive shaft 14 and the housing 3, the sub-gears 15 and 15 do not rotate, and the clip rotating shafts 11 and 11 do not rotate. As a result, the bristle bundles that have been twisted counterclockwise around the respective clip rotation axes 11 and 11 between the clips 5 and 5 are now turned around the rotation axis of the housing 3 as a central axis. It is twisted and knitted.

When the drive lever 6 pushed into the case 2 is urged by the spring 17 and returned to the initial position toward the outside of the case 2, the rotation of the ratchet 20 is applied to the drive shaft 14 as described above. Not transmitted. Thereafter, when the drive lever 6 is pushed into the case again, the clockwise rotation of the ratchet 20 is transmitted to the drive shaft 14, and the housing 3 rotates clockwise with the drive shaft 14. In this way, the bristle bundles sandwiched between the clips 5, 5 can be knitted intermittently clockwise with the rotation axis of the housing 3 as the center axis.

Therefore, according to the hair knitting machine 1, it is easy to twist the hair bundles sandwiched between the clips 5, 5 and knit the twisted hair bundles by twisting them in a short time without skill. Can be done.

During the twisting of the hair bundle sandwiched between the clips 5, 5, the clip rotation axes 11 1, 1 1 are rotated in the reverse direction (clockwise) due to the rebound of the hair. The drive shaft 14, whose rotation is transmitted in both directions via 1, the main gear 12 and the sub gears 15, 15, also makes a reverse rotation (counterclockwise). However, the spring 17 biases the drive lever 16 and, consequently, the rack 16 to the outside of the case 2 to engage with the pinion 19 and the rack. Locking the reverse rotation (counterclockwise) of the ratchet 20 also prevents the drive shaft 14 engaged with the ratchet 20 from counterclockwise rotation (counterclockwise). Therefore, it is possible to prevent the twist of the bristle bundle from returning due to the reverse rotation of the clip rotating shafts 11 and 11.

Further, when the clip rotating shafts 11 and 11 try to rotate in the reverse direction (clockwise) due to rebound of the hair, the spring 30 tightens around the drive shaft 14 and reversely rotates the drive shaft 14 (counterclockwise). ), The reverse rotation of the clip rotating shafts 11 and 11 is also prevented.

When the housing 3 is going to rotate in the reverse direction (counterclockwise) due to the rebound of hair, etc., when the brake 28 is engaged with the housing 3, the brake 28 prevents the housing 3 from rotating in the reverse direction (counterclockwise). When the brake 28 is not engaged with the housing 3, the poles 24, 24 urged by the springs 25, 25 abut against the drive shaft 14, thereby causing repulsion of hair and the like. If it is weak, reverse rotation (counterclockwise) of the housing 3 can be prevented.

Further, when the housing 3 is going to rotate in the reverse direction (counterclockwise), the spring 31 tightens around the cylindrical portion 26 to prevent the housing 3 from rotating in the counterclockwise direction (counterclockwise). By using each of the above configurations alone or in combination with each of the above configurations, it is possible to prevent the housing 3 from rotating in the reverse direction and the hair bundles held between the clips 5, 5 from being twisted and the hair bundles from returning to each other. .

In the hair knitting machine 1 of the above embodiment, the spring 30 is provided to prevent the clip rotating shafts 11 and 11 from rotating in the reverse direction. However, according to cost and necessity, the spring 30 is not provided. You may. Although the spring 31 is provided to prevent the housing 3 from rotating in the reverse direction, the spring 31 may not be provided according to cost and necessity. Industrial applicability INDUSTRIAL APPLICABILITY As described above, the hair knitting machine according to the present invention is useful as a hair knitting machine for twisting a bundle of hair or knitting a twisted bundle of hair when perming or setting.
