If you install 32! 1, a light receiver 133 facing the light emitter 132 is provided at the upper end of the other bracket 1-131;
When the spoked wheel 1 rotates, the photoelectric element of the light receiver 133 detects that the spoke 1d crosses the light from the light emitter 132, thereby detecting the rotation of the spoked wheel 1, and if necessary, converts the detected value into an electric signal. It is possible to extract it as a signal and control each part of the device.

(Function) Next, the function of the apparatus of the present invention configured as described above will be explained.

To detect and correct misalignment of a spoked wheel using this device, first adjust each part of the device to match the size of each part of the spoked wheel to which this device is to be applied.

That is, by driving the motors 13, the hub axle clamping devices A and B each move the sliding base 12 to a predetermined position with respect to the belly button F11 to adapt to the length of the hub axle 1a of the spoked wheel 1 and the hub 1]. Set to .

Its position can be confirmed by the position detector 15.

Once the sliding table 12 is placed in a predetermined position, the cylinder 20 is operated to cause the piston rod 20a to protrude to the maximum extent. In the hub axle clamping device A, the end face of the holder 18 at this time is the reference position, and in the hub axle clamping device B, the spoke wheel is in a state where the cylinder 26 on the sliding v1 stand 24 does not push out the rod 17 and leaves room. The receiver is in the inserted state, and the distance between the left and right holders 18 at this time is set to be slightly larger than the size of the hub portion to be held. The pressing piece 18b provided in the opening of the notch 18a (see FIG. 7), which is the drop-in support portion of the hub axle 1a of the holder 18, is activated as shown in FIG. 7 by keeping the actuator 18e in the retracted position. As shown in FIG.
Rotate it in the direction of arrow H using d.

When the spoked wheel 1 is fed through the chute 21 in this state, the hub axle 1a falls into the notch 18a, and then the actuator 18e is pushed out! Second, the pressing piece 18b is rotated in the direction of the arrow GO in FIG. 7 to restrain the hub axle 1a, and the cylinder 26 of the hub axle clamp device B (see FIG. 6) is operated to push out the rod 17. As a result, the hub axle 1a of the spoked wheel 1 is held between the left and right holders 18.

The spoke wheel 1 used in this apparatus is assembled by an automatic assembly machine, and each spoke 1d is stretched in a substantially normal state.

Further, the positions of the upper plate 31 and the lower plate 32 are set in advance at predetermined positions so as to match the diameter of the spoked wheel 1 to which this device is to be applied. That is, when the motor 36 is driven, the pulleys 33 and 34 are rotated via the belt 38 from the pulley 37, and the shafts 27 and 29 having turnbuckle screws are rotated at the same time, so that the upper plate 31 and the lower plate 32 are rotated. Raise and lower symmetrically. In this case the other two shafts 28, 30 serve as guides. Therefore, by rotating the motor 36 by a desired amount, the upper plate 3 and the lower plate 32 can be set at predetermined positions. Note that the position can be detected by the position detector 130.

To rotate the spoke wheel 1 with the hub axle 1a held between the hub axle clamp devices fA and B as described above,
This is done by the spoke wheel drive device C shown in Figures 4.5, 8, and 9.10. That is, when the cylinder 52 is operated to push out the piston rod 52a, the L-shaped bar 46 rotates in the direction of the arrow I with the shaft 45 as a fulcrum via the pin 55, as shown in FIG. I, shape lever 4
7 also rotates in the direction of arrow J. After inserting the rim 1c of the spoked wheel 1 in this open state, when the cylinder 52 is operated and the piston rod 52a is pulled in, the L-shaped bars 46 and 47 move in the opposite direction from the front with the shaft 45 as the fulcrum. The left and right drive rollers 56 rotate to pinch the rim 1c.

When the motor 61 is driven in this state, the gear box 63
The inner gear 63b rotates, and at the same time, the gears 65 on both sides (one gear via the intermediate gear 64) rotate in opposite directions. Since this rotation is transmitted to the driving roller 56 via the universal chassis 1 [;7,
, the rim 1c is rotated by the rotation of the second roller 5G.

Furthermore, the inconsistency detective i1. The rim 1 of the +iit spoke wheel 1 (, where lateral vibration occurs due to rotation) is horizontal, which is formed integrally with the pivot shaft 45 of the I4 type lever 46, 47. The rod 44 and the host-shaped protrusion 43 slide on the support rod 40 via the spline shaft 41 to absorb the vibration.Furthermore, the vibration of the transmission system of the roller 56 can also be sufficiently absorbed by the universal shaft 67.

Therefore, the spoke wheel 1 can be driven without any problem even if the rim 1c sways.

Furthermore, when the spoke wheel l rotates, the spokes 1d of the wheel 1 pass between the photoelectric devices 132 and 133 shown in FIG. 14, so the amount of rotation can be detected by counting the number of passing spokes 1d. .

In this embodiment, the matarim lateral runout detection device E and the spoke wheel radial runout detection device E (see Figure 11.12) are symmetrical at two locations, upper and lower, respectively (see Figure 1.2). Although it is installed at

In other words, the rim lateral runout detection device moves the L-shaped bars 74 and 75 from the shaft 73 by pushing out the piston rod 80a by operating the cylinder 80 (see FIG. 12) before the spoke wheel 1 is inserted. The left and right copying rollers 85 are in an open state by rotating around the center.

In this state, if the rim 1c of the spoke wheel 1 is positioned between the rollers 85, by operating the cylinder 8o and retracting the piston rod 80a, the left and right copying rollers 85 will come into contact with both sides of the rim 1c, as described above. .

In this state, when the rim 1c rotates and lateral vibration occurs due to misalignment, the copying roller 85 rotates the rim 1c.
The disc 86 swings left and right while being held between the discs, and the lateral movement is transmitted to the spline shaft 69 as described above, resulting in a change in the distance between the disc 86 and the detector 87. Therefore, a change in this interval can be detected by the detector 87.

Furthermore, the spoke wheel radial runout detection device E operates the cylinder 100 (see FIG. 11) to push out the piston rod 100a, so that the horizontal rod 90 is pivoted around the pin 91 before the spoke wheel 1 is inserted. As shown in FIG. 11, the roller 97 is rotated slightly counterclockwise so that the roller 97 is positioned slightly lower than the position shown in the figure. When the rim 1c of the spoked wheel 1 is positioned between the rollers 85 in this state, the cylinder 100 is operated and the piston rod I
By pulling in 00a, move the horizontal rod 90 to pin 9.
By rotating clockwise in FIG. 11 about rim 1c, each of the four copying rollers 97 is brought into pressure contact with the outer peripheral surface of rim 1c.

These four copying rollers 97 are supported at their center positions by a spherical joint 93 so as to be tiltable in all directions, and the roller support rods are supported by fitting the pins 98 into the long holes 99 (see FIG. 12). Since the rotation of the spoke wheel 95 in the horizontal plane and the inclination exceeding a certain limit are restricted, the four copying rollers 97 are always on the rim 1 while the spoke wheel 1 is rotating.
It is possible to maintain contact with the outer peripheral surface of c.

Therefore, when the rotation of the spoke wheel 1 causes vibration in the radial direction, the four profiling holes 97, 97
6, roller support rod 95, spherical joint 94.93,
The horizontal rod 9o swings around the bottle 91 via the member 92. For this reason, the horizontal plate 1 fixed to the outer end of the horizontal rod 9o
04 and the detector 105, and by detecting the variation in the interval with the detector 105, it is possible to detect the runout of the spoke wheel in the radial direction.

In this embodiment, since four copying rollers 97 are used, the runout in the radial direction is detected as an average value at the center point of the spherical joint 93.94, which is the center point of the four copying rollers 97. . And this spherical join)93
．． This is because the center point of 94 coincides with the center of the two copying rollers 85 for detecting lateral shake.

This is convenient because the measurement positions for lateral runout and radial runout are the same.

Next, the misalignment of the wheel is corrected by rotating the spoke nipple 1e at the corresponding position based on the detected runout value number detected by the rim lateral runout detection device E and the spoke wheel radial runout detection device E described above. The operation of the spoke wheel misalignment correction bag ffp will be explained with reference to FIG.

When receiving the spoked wheel 1, operate the cylinder 123 and pull in the piston rod 123a to insert the nipple wrench 121 into the first
Pull it out of the way as shown by the arrow in Figure 3 (a). In this case, the length of the universal shaft 129 will vary somewhat, but this is because the spline shaft 129
It can be absorbed by a. In this state, the spoked wheel 1 is inserted, and as a result of the misalignment detected by the above-described operation, in order to rotate and correct the nipple 1e of the corresponding spoke 1d, first operate the cylinder 123 to push out the piston rod 123a. As shown in FIG. 13(a), the notch groove 121b of the nipple wrench 121
(Refer to FIG. 13(c)) Insert the desired spoke 1d into the inner part so that the spoke 1d is located inside the inner wrench 121c. Next, by operating the cylinder 115 and pulling in the piston rod 115a, the nipple wrench 121 is pulled down as shown by the arrow, and the spanner 121C inside the nipple wrench 121 is fitted into the nipple 1e.

In addition, the above-mentioned centering mechanism during operation 1] o (Fig. 13 (
By the action of b)), the nipple wrench 121 can be moved left and right to a certain extent, and is also allowed to tilt to a certain extent by rotating around the spline shaft 119.

Therefore, angular deviations and slight positional deviations between the spokes 16 are automatically absorbed, making it easier to fit the spanner 121c and the nipple 1e.

Further, after the engagement between the spanner 121c and the nipple 1e is released, the normal state can be restored automatically by the action of the spring 1]Od of the centering mechanism 110.

When the spanner 121c is fitted into the nipple 1e, the motor 126 rotates in a predetermined direction by a predetermined amount by a correction amount based on the detected misalignment value. This correction amount can be determined manually or can be automatically obtained by a computer or the like.

Therefore, if the motor 126 rotates, the coupling 12
7, gear box 128, universal shirt number 29,
A spanner 121c is rotated via the input shaft 121a to rotate the nipple 1e a predetermined amount to correct the misalignment. In this case, the stop position of the spanner 121C is gear box 1.
A known fixed position stop mechanism provided in the wrench 1
The opening 21c is the notch groove 121b of the nipple wrench 121.
It will stop at the position that matches.

When this correction is completed, push out the piston rod 115a of the cylinder 115 and push up the nipple wrench 121 slightly to move the spanner 121C to the nipple 1e.
After removing the piston rod 123 of the cylinder 123
By retracting the nipple wrench 121 in the direction of the arrow, the wheel 1 can be rotated by the required amount again.

By repeating the above operations as many times as necessary, misalignment of the spoke wheels can be detected and corrected.

As for the actual work procedure, for example, first, the spoked wheel 1 is rotated, and the misalignment of each part of the wheel is detected by the lateral runout detection device and the spoked wheel radial runout detection device E, and this is input into the computer. Then, after correcting each part of the wheel that requires correction using the spoke wheel misalignment correction device F, the degree of alignment of the wheel after correction is detected using the detection device, and correction is made again if necessary. I do.

When the spoke wheel 1 correction work is completed as described above, the piston rod 52a of the cylinder 52 of the spoke wheel drive bag 2c is pushed out to separate the drive roller 56 from both sides of the rim IC, and the rim lateral vibration detection device The piston rod 80a of the cylinder 80 is pushed out to separate the copying roller 85 from the rim IC, and the piston rod 1 of the cylinder 100 of the spoke wheel radial runout detection device E is pushed out.
By not pushing out 00a, the copying roller 97 is moved to the rim 1c.
away from the outer periphery of the hub axle clamp devices A and B in this state.
By retracting the actuator 18e of each holder 18, the pressing piece 18b is rotated upward in the direction of arrow H in FIG. 7 by the action of the spring 18d, releasing the restraint on the hub shaft 1a, and By retracting the piston rods 20a of the cylinders 20 on both sides, the hub axle 1a is removed from each holder 18. Since the escaped hub shaft 1a is supported by the chute 22, this inclined chute 22
The spoke wheel 1 is ejected to the outside.

(Effects of the Invention) As described above, the rim lateral runout detection device in the spoked wheel misalignment detection and correction device of the present invention maintains the hub axle of the spoked wheel in a fixed position with respect to the frame of the device to prevent the spoked wheel from moving. Since the system detects the lateral runout of the rim while rotating and swinging along the misaligned rim, it is easier to detect the lateral runout of the rim than with the conventional detection device that moves the knob/axis. An excellent effect is obtained in that accuracy can be significantly improved.

Further, since the rim lateral runout detection device of the present invention is compactly installed near the rim of a spoked wheel separately from other devices, it also has the advantage of being relatively simple and compact in structure.
