And synchronously rotate the three members 1 and 2 and 3a, 3b integrally.

As a result, the regulating plates 3a and 3b are provided with the connecting rods 15a and 15b as the power transmitting means, and the rotational force of the planting board 1 is applied thereto, and the transmitting rod 16 is further applied with the rotational force. Therefore, the connecting rods 15a and 15b are not inserted into the planting board 1 or the regulating plates 3a and 3b to function as power transmitting means, and only the transmitting rod 16 has a power transmitting function. 15a, 15
b functions as power transmission means from the planting board 1 to the regulating plates 3a, 3b, and the transmission rod 16 is connected to the two members 1 and 3a, 3b.
It is possible to adopt a structure that does not serve as a power transmission means between b.

Although not shown, the transmission rod 16 is, for example, erected on the aligning plate 2 and inserted through the regulating plates 3a, 3b and the implanting plate 1 so that the rotational driving force of the implanting plate 1 is adjusted by the aligning plate 2 and the regulating plate. 3a,
3b. Alternatively, as shown in FIG. 1, the transmission rod 16 is implanted on another rotating plate 17 that rotates integrally and synchronously with the implanting plate 1 and the like, and is vertically suspended in parallel with the rotation axis X. It is inserted into the plate 1 and the regulating plates 3a, 3b to serve as rotation transmitting means.

The rotary plate 17 is made of a disk, which is loosely inserted into a rotary drive shaft 9 connected to the center of the planting board 1 and is rotatably installed at a fixed position. That is, the rotating plate 17 is installed at a fixed position so as to be rotatable about the same axis X as the other plates 1, 2, 3a and 3b.

For example, as shown in FIG. 1, a base 18 made of a disk into which the drive shaft 9 can be loosely inserted is fixedly provided on a frame 19, and a lower surface of an outer circular portion of the fixed base 18 has a concentric circle with the drive shaft 9. Fixed outer ring 2 (with rotation axis X as the axis)
0, and the fixed outer race 20 has a ball bearing 2
A movable inner ring 22 is provided which is connected to the movable inner ring 22 via the first inner ring 1. Therefore, the rotary plate 17 and the movable inner ring 22 are arranged concentrically around the rotation axis X (drive shaft 9), and are loosely inserted into the drive shaft 9.

The transmission rod 16 fixed to the movable inner ring 22, that is, substantially fixed to the rotary plate 17 is suspended from the rotary plate 17, and the transmission rod 16 is attached to the planting plate 1 and the regulating plate 3 a. , 3b and the alignment plate 2, and the transmission rod 16

And the aligning plate 2 rotate synchronously integrally about the axis X.

The rotating plate and the aligning plate 2 are connected by a connecting member 23. A plurality of the connecting members 23 are arranged at equal intervals on a circular locus about the rotation axis X, that is, at a position off the rotation axis X, thereby suspending the alignment plate 2 on the rotation plate 17. In addition to being installed at a fixed position, the rotational force of the rotating plate 17 is applied to the alignment plate 2 via the connecting member 23.

Therefore, a rotational driving force is applied to the alignment plate 2 from the planting plate 1 and the rotating plate 17 by both the transmission rod 16 and the connecting member 23. Therefore, it is possible to adopt a configuration in which the transmission rod 16 does not pass through the alignment plate 2 and only the connecting member 23 has a rotation transmission function. For example, a bolt and a nut can be used as the connection tool 23.

In the embodiment, a plug socket type is adopted as shown in FIGS. This plug-and-socket type locking means is known per se,
Is automatically inserted into the socket 25, and the coupling can be released by moving the outer peripheral coupling 26 in the plug removal direction with fingers.

In this embodiment, one of the plug 24 and the socket 25 is vertically mounted on the lower surface of the outer circular portion of the rotary plate 17, and the other is vertically mounted on the upper surface of the outer circular portion of the alignment plate 2. The socket 25 was disengaged and separated.

In short, when the plug 24 is pushed into the socket 25, the cylindrical pressure receiving piston 27 in the socket 25 is pressed by this and slides inward in the axial direction while compressing the spring 28, and the piston 27 is compressed. The internal ball regulating piece 29 provided integrally with the ball 30 releases the regulation of the ball 30.

As a result, the coupling 26 moves outward in the axial direction by the elastic force of the spring 31, and the coupling 2
The ball 3 is provided by an external ball regulating piece 32 provided integrally with the ball 3.
0 is pushed inward to engage with the key groove 33 provided on the plug peripheral surface. As a result, the plug sockets 24 and 25 are connected, that is, the rotary plate 17 and the alignment plate 2 are connected.

When the coupling 26 is moved against the spring 31, the regulation of the ball 30 by the external ball regulating piece 32 is released. As a result, the pressure receiving piston 27 pushes the ball 30 outward and moves the ball 30 outward in the axial direction. And the inner ball regulating piece 29 regulates the ball 30. Accordingly, the engagement of the ball 30 with the plug 24 is released, the plug sockets 24 and 25 are released in the axial direction, and the alignment plate 2 can be separated in the axial direction.

After releasing the connecting member 23, the bolt 1
0, the alignment plate 1 and the regulating plates 3a, 3b
And the planting board 1 are simultaneously separated from the drive shaft 9 in the axial direction to contribute to replacement of the brush rod 4. Regulating plate 3a,
Tool insertion holes 34 and 35 centering on the axis X are formed in the center of the alignment plate 2 and 3b, and the bolt 10 is tightened or released through the tool insertion holes 34 and 35.

FIGS. 5 and 6 show the alignment plate 2 and the restriction plates 3a and 3 respectively.
b and the arrangement state of the brush rod 4 (planting hole 6), the connection rods 15a and 15b, the transmission rod 16, and the connection tool 23 corresponding thereto are illustrated. FIG. 5 shows an example of a structure in which the connecting tool 23, the transmission rod 16, and the connecting rods 15a and 15b are arranged on a circular locus different from the circular locus on which the brush rods are arranged to increase the brush implant density. FIG. 6 shows that the transmission rod 16, the connecting rods 15a, 15b and the connecting member 23 are arranged on a circular locus on which the brush rod is arranged, and
3 shows an example of a structure in which the diameters of 3a, 3b and 17 are reduced and the entire apparatus is reduced in size.

As shown in FIG. 1, the motor 8 for driving the rotary brush is supported by a loading platform 36, which can be moved up and down by a guide stay 37, and the air cylinder 13 is vertically attached to the vertical frame 19. The cylinder rod is directly connected to the loading platform 36, and the loading platform 36 and the motor 8 are moved up and down by the expansion and contraction operation of the cylinder 13.

As described above, the brush rod planting plate 1 is connected to the rotary drive shaft 9 which is a motor shaft suspended from the motor 8, and the planting plate 1 connected to the rotary drive shaft 9 by lowering the motor 8. Is lowered together with the brush rod 4. As a result, the tip of the brush rod 4 protruding from the alignment plate 2 is adjusted. That is, the tip is adjusted so that the tip of the brush always projects by a fixed amount from the alignment plate in accordance with the wear of the brush rod.

Thus, as shown in FIG.
When the planting board 1 moves closer to the alignment plate 2 due to the further progress of the abrasion, the second brush rod regulating plate 3b moves to the alignment plate 2
While keeping this superposed state, only the planting board 1 and the regulating board 3a are integrally moved downward in the direction approaching the alignment board 2, and the hair tip adjustment can be continued. While the planting board 1 and the control board 3a are descending, the second control board 3b is suspended.
The upper end of the connecting rod 15b gradually protrudes above the upper surface of the planting board 1, and allows the planting board 1 and the regulating plate 3a to move downward.

Similarly, the first and second brush rod regulating plates 3
When the abrasion progresses until the a and 3b overlap the upper surface of the alignment plate 2, only the planting plate 1 alone descends while the first and second connecting rods 15a and 15b protrude upward from the planting plate 1, and the hairs are removed. It is a configuration that can be adjusted ahead. This configuration increases the effective usage of the brush rod and is extremely economical. The present invention suggests a case in which a plurality of the brush rod regulating plates 3a and 3b are provided, but the number may be one according to the rod length.

[0041]

According to the present invention, the problem of lateral warpage of the rod can be effectively solved by the restriction plate through which the brush rod disposed between the planting plate and the alignment plate can be inserted, and the brush rod restriction plate is rotated. Since the connecting rod arranged at a position off the axis is connected to the brush rod planting plate, the relative installation state of the regulating plate with respect to the planting plate and the alignment plate is properly secured, and the effect of preventing side warpage can be fully exhibited. In addition to this, it is possible to adopt a configuration in which the assembly of the regulating plate is simplified, and the rotational driving force of the brush rod planting plate is transmitted to the regulating plate via the connecting rod.

In the present invention, the brush rod restricting plate is moved together with the brush rod implanting plate via the connecting rod, thereby adjusting the bristle tip length of the brush rod projecting from the alignment plate while exerting the restricting action of the restricting plate. We can do without trouble.

Also, according to the present invention, even after the abrasion of the brush rod progresses and the regulating plate overlaps the alignment plate, the brush planting plate is independently moved so as to approach the alignment plate by using the connecting rod as a guide. Enables protruding hair tips from the alignment plate,
The effective use length of the brush rod can be increased.

Further, according to the present invention, by installing a plurality of the regulating plates at an interval, the effect of preventing the brush rod from warping can be improved, and the regulating plate can be moved by using the connecting rod as a guide. Together, it is possible to provide a plurality of regulating plates. However, the hair tips can be properly adjusted by moving the planting board.

Also, the present invention provides a method of fixing the alignment plate by detachably connecting the brush rod alignment plate to a rotation plate installed rotatably at a fixed position by a connecting tool arranged at a position deviated from the rotation axis. The position setting and the constant level rotation are guaranteed, while the brush rod implanting plate moves toward the alignment plate, and the hair tip adjustment can be properly performed.

By releasing the connection of the brush rod implanting plate to the drive shaft by releasing the connection by the connecting tool,
The alignment plate, the regulating plate, and the planting plate can be easily removed from the three members, so that replacement and reassembly of the brush rod can be easily performed. Further, by assembling the connecting tool into a plug socket structure, the assembling and assembling release are further simplified.
