The rotation of the spoke wheel 1 is detected by detecting this with the photoelectric element of the light receiver 133, and if necessary, the detected value can be extracted as an electric signal to control each part of the apparatus.

(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, the hub axle clamp devices A and B each center the slide table 12 in a predetermined position corresponding to the length of the hub axle 1a and the hub 1b of the spoke wheel 1 by driving the motor 13. do.

Its position can be confirmed by the position detector 15.

Once the slide table 12 is set at 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 receiver is in a state where the cylinder 26 on the sliding table 24 leaves room for pushing out the rod 17. In this state, the distance between the left and right holders 18 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 a drop-in support for the hub axle 1a of the holder 18, can be pressed by placing the actuator 18e in the retracted position, as shown in FIG. The pressing piece 18b is pressed against the spring 18d.
Rotate it in the direction of arrow H.

When the spoked wheel 1 is fed through the chute 21 in this state, the hub axle 1a falls into the notch 1))a, and then by bringing out the actuator 1)(e), the pressure Ji'1llb is reduced. Rotate in the direction of arrow G in Fig. 7 to hold down the hub axle 1i+, and push the rod 17 by operating the cylinder 26 of the hub axle clamping device B (see 1(a) in Fig. 6). Depending on the outcome, the left and right halter-1
The hub axle 1a of the spoke wheel I is held between the spoke wheels 8 and 8.

Furthermore, the spoke wheel 1 involved in this device is automatic &:lI.
1" and 7", and each spoke 1d is tensioned almost in its normal state.

Also, the position 4) of the upper plate 31 and lower plate 32,
The spokes are placed in a predetermined position in advance to match the diameter of the spoke wheel 1 to be applied to this device.

That is, when the motor 36 is driven, the boots IJ 33 and 34 are rotated from the pulley 37 via the belt 38, and the shafts 27 and 29 having turnbuckle type screws are also rotated, so that the upper plate 31 and the lower plate 32 are rotated. Raise and lower symmetrically. In this case, the other two shafts 2Fl, 30 serve as guides. Therefore, by rotating the motor 36 by a desired amount, the upper plate 31 and the lower plate 3 are rotated.
2 can be placed in place. Note that the position can be detected by the position detector 130.

As described above, the spoke wheel 1 with the hub axle 1a held between the hub axle clamp devices A and H is rotated by the spoke+1i wheel drive device C shown in FIGS. 4.5, 8, and 9.10. That is, when the cylinder 52 is operated to push out the screw 52a, the L-shaped bar 46 rotates in the direction of the arrow I about the shaft 45 via the pin 55, as shown in FIG. Then, the I7 type lever 47 also rotates in the direction of the arrow (■). After inserting the rim IC of the spoke 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 rotate in the opposite direction about the shaft 45 to pinch the left and right driving rollers 56 J and lc.

If the motor is driven by 1 in this state, the gear box 63
The inner gear 6311 rotates, and at the same time I'I1 on both sides
The first wheels 65 rotate in opposite directions (via one tooth +li l and intermediate tooth jlt64). Since this rotation is transmitted to the driving roller 56 via the universal shirt I 67, the rim 1c rotates due to the rotation of the respective roller 56.

Note that the rim 1c of the spoke wheel 1 before correction of misalignment causes lateral vibration due to rotation, but this lateral vibration is caused by the L-shaped bar 4.
A horizontal rod 44 and a boss-shaped protrusion 43 formed integrally with the pivot shaft 45 of 6.47 are attached to the support rod 4 via a spline shaft 41.
Absorb by sliding through 0. Also, vibrations in the transmission system of the roller 56 can 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 1 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 measuring the number of passing spokes 1d. can.

In addition, in this embodiment, the rim lateral runout detection device I and the spoke wheel radial runout detection device E (see Figure 11.12) are located symmetrically at two locations below -L (see Figure 1.2). (see figure), and its functions are as follows.

That is, before the spoke wheel 1 is inserted into the rim, the rim lateral runout detection device pushes out the piston rod Boa by operating the cylinder 80 (see FIG. 12).
The L-shaped bars 74 and 75 are rotated about the shaft 73, and the left and right copying rollers 85 are in an open state.

If the rim 1c of the spoked wheel 1 is positioned between the rollers 85 in this state, by operating the cylinder 80 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.
It swings left and right while holding the disc, and the lateral movement is transmitted to the spline shaft 69 as described above, and as a result, the distance between the disc))[; and the detector 87 changes. Therefore, ゛(, detect the change in the interval of 2! it 117 c: 2J,
can be detected.

Also, a spoke wheel radial runout detection device TCε,1,
Before inserting the spoke wheel 1 into the receiving & J position, by operating the cylinder 100 (see Fig. 11) and pushing out the piston mouth/nod 100a, the horizontal rod 90 is moved slightly counterclockwise in Fig. 11 using the pin 91 as a fulcrum. The roller 97 is rotated so that the roller 97 is located slightly below the position shown in the figure. In this state, the rim IC of the spoke wheel 1 is at the roller 85.
Once located between them, by operating the cylinder 100 and pulling in the piston rod 100a, the horizontal rod 90 is rotated clockwise in FIG. 97 each on the rim
Press it against the outer peripheral surface of c.

These four copying rollers 97 are supported at their central positions by a spherical joint 93 so as to be tiltable in all directions, and are supported by a roller support rod by fitting a pin 98 into a long hole 99 (see FIG. 12). Rotation in the horizontal plane of 95 and inclination exceeding a certain limit are restricted 11, so during the rotation of the spoke wheel 1, four (11% rl-ra f)7
can maintain contact with the outer peripheral surface of the rim 1c at all times.

Therefore, when the rotation of the spoke wheel 1 causes vibration in the radial direction, the four copying rollers 97 and the
6, "1-ra support rod 95, spherical joint 94.93
, a horizontal rod 90 swings about a pin 91 via a member 92. As a result, the distance between the horizontal plate 104 fixed to the outer end of the horizontal rod 90 and the detector 105 fluctuates, and by detecting the fluctuation in the distance with the detector 105, the runout of the spoke wheel in the radial direction can be reduced. can be detected.

In this embodiment, since four copying rollers 97 are used, the radial runout is detected as an average value at the center points of the spherical joints 93 and 94, which are the center points of the four copying rollers 97. And this spherical joint 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, based on the run-out detection value detected by the lateral run-out detection device η[) of the above-mentioned wheel J and the spoke wheel radial run-out detection device E, the spoke nipple 1e at the corresponding position is rotated. The operation of the spoke wheel misalignment correcting device F for correcting misalignment 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 (see FIG. 13(c)) so that the spoke 1d is positioned within the spanner 121c of the instep. Next, by operating the cylinder 115 and retracting the piston rod 115a, the nipple wrench 121 is pulled down as shown by arrow 7, and the spanner 121C inside the nipple wrench 121 is fitted into the nipple 1e.

It should be noted that the above-mentioned centering mechanism 110 during operation (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 spring 110d of the centering mechanism 110 automatically restores the normal state.

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 compling 12

9. The spanner 121C is rotated via the input shaft 121a to rotate the nipple 1e by a predetermined amount to correct the misalignment.

In this case, the stop position of the spanner 121C is such that the opening of the spanner 121C is aligned with the notch groove 12 of the nipple wrench 121 by a known fixed position stop mechanism provided in the gear box 128.
It stops at the position that matches 1b.

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 spoke wheel L is rotated, and misalignment of each part of the wheel is detected by the lateral runout detection device and the spoke wheel radial runout detection bag HE, and this is detected by 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 if necessary, Make the correction again.

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 device C is pushed out to separate the drive roller 56 from both sides of the rim 1c, 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 roughly pushed out.
By pushing out 00a, the copying roller 97 is moved to the rim IC.
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 as shown by arrow H in FIG. 7 by the action of the spring 18d, releasing the restraint on the hub axle 1a, and By retracting the piston rod 20a of the cylinder 20, 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, according to the spoke wheel radial runout detection device in the spoke wheel misalignment detection and correction device of the present invention, the radial runout of the spoke wheel at the same position as the lateral runout detection position of the rim can be detected. Since it is possible to detect the lateral runout of the rim at the same time, it is possible to improve the accuracy of detecting misalignment of spoke wheels and to significantly improve the efficiency of detecting and correcting misalignment of spoke wheels.
