Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for attaching anti-slip spikes to a plurality of gaps previously provided in the tread of a tire.

Conventionally, in the process of driving anti-slip spikes into multiple holes in the tread of a tire, the tire is rotatably supported on a tire support device with its center axis horizontal, and a worker is required to drive each hole into each hole. The method used was to visually match the driving direction of a spike driving machine with the holes provided in the tire tread and then drive the spikes.

However, in this method, a great deal of time and effort is spent on positioning each hole. In other words, due to the axial deviation of the tire or the radial change in the tire tread position that occurs during tire rotation, the operator may have to shift the tire axially to align it, or increase the driving depth of the spike driving machine. In order to adjust the spike driving machine, the tire proximity distance adjustment had to be performed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method and apparatus that makes it possible to automatically attach spikes to all holes provided all around the tread of a tire by simply setting the tire in a predetermined position. .

In a method of attaching anti-slip spikes to the tread of a tire, the tire is attached to a tire support mechanism that rotates the tire about a predetermined rotation axis, and then pressure is applied to the tire attached to the tire support mechanism. When filling with air and then attaching the spike to the tread by the command of the control mechanism,
Since the rotating shaft is rotatable and the spikes are attached to the tread while the driving direction is held substantially perpendicular to the tread of the tire, the attachment reaction force when attaching the spikes is absorbed by the tire. The load can be elastically applied using pressurized air, which prevents tire damage without applying unreasonable force or excessive impact force to the tire, and prevents circumferential misalignment between the tire spike hole and the spike. Even if this occurs, the tire can freely rotate by a minute angle and this deviation can be corrected.

Further, in the present invention, spikes are attached to the tire that is attached to the tire support mechanism and filled with pressurized air in a freely rotatable state, and then the tire is rotated by a predetermined amount of rotation, and this is alternately repeated. The tire can be equipped with spikes around the entire circumference of the tread of the tire.

Furthermore, in the present invention, after all the spikes are attached to the tire, the pressurized air filled in the tire is discharged, and finally, the tire is removed from the tire support device, and the tire without spikes is returned to the tire support device. By attaching the spikes and repeating this process, it is possible to efficiently attach the spikes to the tire one after another.

Moreover, the present invention provides a device for attaching anti-slip spikes to the tread of a tire, including a tire support mechanism that rotates the tire around a predetermined rotation axis, and a tire that is attached to the tire support mechanism that is filled with pressurized air. and a pressurized air filling mechanism for discharging the air, a plurality of spike driving means for driving spikes into the tread of the tire, a spike driving means support part for supporting the plurality of spike driving means, and a spike driving means support part for supporting the plurality of spike driving means, and held by the tire support mechanism. a spike driving mechanism comprising: a following means for following the fluctuation in the direction of the rotational axis of the tire; and a horizontally moving part supporting the spike driving means support part, which is movable in the direction of the rotational axis of the tire support mechanism by the following means. and a proximity support mechanism that supports the spike driving mechanism so as to be able to approach the tire; and a spike driving means is operated with the rotation shaft of the tire support mechanism being rotatable, and then the rotation shaft of the tire support mechanism is operated. Rotate by a predetermined amount of rotation,

Next, the tire 20 is manufactured using the apparatus of the embodiment described above.
An example of a method for injecting a spike into zero will be described.

First, the tire 200 is placed on the tire support plate 65,
By shortening the lift cylinder 61, the tire support plate 6
5 and the tire 200, and the rotating shaft 13,
17 and the center of the tire 200, and then extend the air cylinder 25 of the tire mounting/removal means 20 and shorten the horizontal movement cylinder 63 of the tire lifting means 60.
0 is fitted with the left rim 11 and the right rim 15.

Next, when the rim lock cylinder 48 of the tire rotation drive means 30 is extended, the lock shaft 46 and the guide ring 49 are attached to the left disk 12 in FIG.
The bell crank 52 is rotated in the direction of the hour hand as shown in FIG. and the rims 11 and 15 are locked.

After the rims 11 and 15 are locked, the tire 2 is released from the rotor seal 28 through the left rotating shaft 13, the left disc 12, and the air passage 14 in the left rim 11.
When compressed air at the required pressure (approximately 5 kg/cm ² ) is supplied into the tire 200 and the lift cylinder 61 is extended, the tire 200 is firmly fitted to the rims 11 and 15 and can withstand spike driving. expanded to a certain degree of hardness.

When the gripping cylinder 96 of the following means 90 is further extended, the swinging lever 92 swings, and its lower end roller 93 moves the sidewall 2 of the tire 200.
00a is held, and by the operation of the following means 90, the horizontally moving portion 80 is appropriately moved left and right, and the center of the spike driving mechanism 150 is aligned with the center of the tire 200 in the width direction.

After completing the preparation for spike driving in this way,
Of the six spike driving means 120 in two left and right rows, the spike hole expanding claw 140 of the leftmost spike driving means 120 (see FIG. 8) in the left and right rows is connected to the tread 200b of the tire 200. After manually aligning with the upper spike hole 200c (indicated by – in FIG. 8),
When the spike driving is started, two spikes are driven into the spike hole 200c at the location labeled 1, as shown in the explanatory diagram of FIG. 13.

Specifically defining this spike driving operation, the spike hole expanding claw 140 is inserted into the tire tread 2.
With the spike hole 200c aligned with the required spike hole 200c on 00b, a friction-reducing liquid such as water is ejected into the spike hole 200c into which the spike is to be driven, and when the pushing means elevating cylinder 133 is extended, the driving gun body 135 is lowered together with the piston portion 134, and when the presser piece 142 comes into contact with the tread surface 200b of the tire 200, the spike hole expanding claw 140 fits into the spike hole 200c. Even after the presser piece 142 collides with the tire tread surface 200b, the pressure contact coil spring 144 can be elastically deformed and shortened, so the driving gun main body 135 continues to descend, and the spike hole expanding claw 140 deeply enters the spike hole 200c. can do.

When the base piece 145 of the spike hole expanding claw 140 collides with the holding piece 142, the driving gun body 13
However, when this state is reached, the spike driving cylinder 136 is actuated by a signal transmitted from a detection means such as a limit switch (not shown), and the driving rod 138 is activated.
is lowered, and the spikes previously supplied from the spike guide chute 139 to the spike guide holes 146 are driven into the required spike holes 200c to a predetermined depth by the lowering of the driving rod 138.

In this way, after completing the spike driving shown in Figure 1,
The driving means elevating cylinder 133 and the spike driving cylinder 136 move back, and then the brake 36 of the tire rotation drive means 30 is released, the clutch 35 is engaged, and the variable speed motor 33 rotates at high speed. Start. and encoder 4
When the number of pulses transmitted by 1 reaches about 70% of the number of pulses required to reach the next spike hole 200c, the variable speed motor 33 is switched to low speed and reaches the next spike hole 200c. When the number of pulses from the encoder 41 matches the value obtained by subtracting the number of pulses corresponding to the overrun amount from the number of pulses required for The brake 36 is also operated, and as a result, the tire 200 is accurately rotated by an angle corresponding to the spacing between the spike holes 200c on the same row, and is ready for the next spike driving.

Note that after the brake 36 is activated and before the spike driving operation is performed, the brake 36 becomes inactive again, and the tire 200 becomes rotatable.
Even if there is a slight error in rotation amount of 0, it will be automatically corrected.

Next, by operating the six spike driving means 120 all at once, one spike can be simultaneously driven into each of the six spike holes 200c according to the pattern shown in FIG.

Such a spike driving operation is repeated to drive the spikes over almost the entire circumference of the tire tread 200b, and in the final stage, unlike the first stage, the rightmost spike driving means 120 (the first spike driving means 120) in the left row and the right row (see Figure 8), and drive two spikes by operating the chisel (see Figure 13).
4, 14). Although most of the arrangement of the tire spike holes 200c shown in FIG. 13 is a standard pitch of equal pitch,
Between the spike holes 200c represented by 13 in the first and fourth rows from the top in FIG. 13 and the spike holes 200c represented by 2 in the third and sixth rows from the top,
It's becoming an irregular pitch.

After completing the spike driving operation, rotor seal 28
When the compressed air in the tire 200 is discharged through the air passage 14 and the gripping cylinder 96 is shortened, the lower part of the swing lever 92 is expanded.

Then, by shortening the rim lock cylinder 48 and moving the lock shaft 46 to the right,
The locking piece 54 can be withdrawn from the cylindrical guide member 50 to release the rim lock state.

Next, the lift cylinder 61 is shortened and the tire support plate 65 is moved to the tread 200b of the tire 200.
After contacting and supporting the tire 200, the tire 200 can be removed from the rims 11, 15 by shortening the air cylinder 25 of the tire mounting/removal means 20 and expanding and contracting the horizontal movement cylinder 63 of the tire lifting means 60. .

Finally, by extending the lift cylinder 61 of the tire lifting means 60 and lowering the tire support plate 65, the tire 200 can be taken out from the spike mounting device.

In this manner, in the above embodiment, if the spike driving position is first set visually, then the spikes are automatically placed in the spike holes 200c on the tread 200b over the entire circumference of the tire 200 within a short period of time. can be driven efficiently, resulting in significant labor savings.

Also, when driving spikes, use a tire with a tire size of 200
By applying air pressure to the tire 200, the spike holes are expanded to some extent, and the driving of the spikes can be carried out without difficulty, but at the same time, no excessive driving force or impact force is applied to the tire 200, and no damage is caused to the tire. There is no risk of being hit.

Furthermore, even if the tread 200c of the tire 200 is not always constant with respect to the center plane perpendicular to the tire rotation axis, and is curved slightly to the left and right, the swinging lever 92 that pivots the roller 93 allows the tread to be followed. The means 90 is activated, and the spike driving means 120 automatically follows the deformation of the tire 200 to the left and right, so that the spike hole expanding claw 140 is accurately aligned with the spike hole 200c, and the spike driving is ensured. carried out.

Furthermore, the tread 200b of the tire 200
Even if the spike is not always at a constant radial position from the center of the tire, the spike can always be driven into the tread 200b to a constant depth without being affected by the holding piece 142 and the base patch 145. be able to.

Furthermore, by measuring the circumferential spacing between the spike holes 200c of the tire 200 and storing this value in the control device, the circumferential spacing of the spikes into the spike holes 200c can be set accurately to the circumferential spacing of the spike holes 200c of the tire 200. can be matched.

In addition, if the width direction spacing and circumferential direction spacing of the spike holes 200c of the tire 200 are different, the axial slide plate 108 and the circumferential slide plate 114 are adjusted appropriately in the width direction and circumferential direction of the tire in accordance with the variation in the spacing. When the spike driving means 1 is adjusted, the inclination adjustment knob 129 is operated appropriately.
By adjusting the inclination angle of 20, spikes can be driven into tires of any spike hole spacing and tire size. In this case, it is necessary to store such data in the storage device of the control device.

Furthermore, once the operator performs the alignment during the first spike driving stage,
Since spike driving can be performed automatically, the burden on the operator can be significantly reduced.

Moreover, as described above, according to the embodiment,
It follows even the slightest deformation of the sidewall 200a and tread 200b of the tire 200, and it is possible to accurately drive spikes into the tread 200b at a predetermined angle and depth, thereby unduly increasing the running resistance of the tire. Otherwise, the required grip force on the road surface can be maintained.

As explained above, according to the present invention, by using a plurality of spike driving means, driving can be completed in a short time, and adjustments can be made automatically for deviations in the position of the tire tread in the tire axial direction that occur during tire rotation. This makes it possible to perform automated tasks that are far more productive than traditional methods that rely heavily on human hands.

Although the present invention has been described above with reference to the embodiments illustrated in the drawings, the present invention is not limited to such embodiments, and the design can be freely modified within the scope of the spirit of the present invention. .
