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 erected on the aligning plate 2 and inserted into the restricting plates 3a and 3b and the implanting plate 1 so that the rotational driving force of the implanting plate 1 is aligned with the aligning plate 2 and the restricting plate. 3a,

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 composed of a disc, which is loosely inserted into the rotary drive shaft 9 connected to the center of the implant plate 1 and 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 disc on which the drive shaft 9 is loosely inserted is fixedly provided on a frame 19, and the fixed base 18 has a lower surface of an outer circular portion concentric with the drive shaft 9. Fixed outer ring 2 (with rotation axis X as axis)

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 connector 23 has a rotation transmission function. As the connecting tool 23, for example, a bolt nut can be used.

In the embodiment, a plug socket type is adopted as shown in FIGS. This plug-and-socket type locking means is known per se, and the plug 24
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
Ball 3 by means of an external ball restricting piece 32 provided integrally with 6
0 is pushed inward and engaged with the key groove 33 provided on the peripheral surface of the plug. As a result, the plug sockets 24 and 25 are connected, that is, the rotating plate 17 and the aligning 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. Therefore, 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
By releasing 0, the alignment plate 1 and the regulation plates 3a, 3b
And the planting plate 1 are separated from the drive shaft 9 in the axial direction at the same time to contribute to the replacement of the brush rod 4. Regulating plate 3a,
Tool insertion holes 34 and 35 centering on the axis X are formed in the central portions of 3b and the alignment plate 2, 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 for this are illustrated respectively. 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
An example of a structure in which the diameters of 3a, 3b, and 17 are reduced to downsize the entire apparatus is shown.

As shown in FIG. 1, the motor 8 for driving the rotary brush is supported by a loading platform 36, and the loading platform 36 can be raised and lowered 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 bed 36 so that the bed 36 and the motor 8 can be moved up and down by the expansion and contraction 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 bristle tip length 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. 3, the brush rod 4
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 wear progresses until a and 3b overlap the upper surface of the aligning plate 2, the first and second connecting rods 15a and 15b are projected upward from the planting plate 1, and only the planting plate 1 is lowered alone. This is a configuration that allows for pre-adjustment. 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]

The present invention can effectively solve the problem of lateral warp of the rod by the regulating plate which is provided between the planting plate and the aligning plate and through which the brush rod can be inserted, and at the same time, rotating the brush rod regulating plate. Since it is connected to the brush rod planting plate by a connecting rod arranged at a position off the axis, the relative installation state of the regulating plate with respect to the planting plate and the aligning plate can be properly secured and the lateral warpage prevention effect can be fully exhibited. In addition, the assembly of the regulation plate can be simplified, and the rotational driving force of the brush rod implanting plate can be transmitted to the regulation 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.

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

According to the present invention, the effect of preventing lateral warpage of the brush rod can be improved by installing a plurality of the regulation plates at intervals, and the regulation plate can be moved by using the connecting rod as a guide. Together with this, it is possible to install multiple control 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,
It is easy to remove the alignment plate, the regulation plate, and the planting plate, so that the brush rod can be easily replaced and reassembled. Further, by assembling the connecting tool into a plug socket structure, the assembling and assembling release are further simplified.
