[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for automatically assembling a tire to a hub of a vehicle, and particularly to an assembling method suitable for attaching a tire to a hub of a non-driving wheel. It is something. [Prior Art] In recent years, tires have recently been automatically assembled by robots and the like instead of manually. To automatically assemble a tire, the hub bolt provided on the hub must be aligned with the bolt hole provided on the tire side, and the tire must be attached to the hub. Therefore, conventionally, Japanese Patent Laid-Open Nos. 59-227502 and 63-6
As disclosed in Publication No. 8478, using equipment equipped with a tire mounting unit with a hand unit, a tire phasing device, a hub bolt position regulation/detection device, a nut delivery unit, etc., it is possible to install tires according to the vehicle in advance. The tire is adjusted to the specified phase using the tire phasing device, held by the hand unit of the tire mounting unit, and the specified nut is supplied to the nut runner of the nut delivery unit. When the vehicle is delivered to a predetermined position, the hub bolt phase regulation/detection device detects the inclination of the vehicle's hub and the position of the hub bolt.Based on the detected data, the tire mounting unit is aligned with the hub. The tire is held by a hand unit and mounted opposite the hub. After installing the tire, tighten the nut on the hub bolt using a nut runner to complete the assembly. (What the invention is trying to solve!!llB) The hand unit that holds the tire has a main body (
Support parts (2a) (2b) (
2c) and each support part (2a) (2b) (
Attach hands (3a) (3b) (3c) to 2c) so that they can slide freely, and attach each hand (3a) (3b) (
3c) is opened and closed by sliding it in the radial direction using an appropriate means (not shown). As shown in Fig. 6, the above-mentioned hand unit holds the three outer JII parts of the tire (4) with each hand (3a), (3b), and (3c), and after attaching it to the hub, hands (3a) (; Th) (
3c) to the outside, releasing the tire (4) and escaping. Therefore, when installing the tire, depending on the phase of the hub, the hands of the hand unit (3a) (3b) (3c)
When one of these enters the narrowest part between the tire (4) and the wheel house (5) and releases the tire (4),
The hand that moves outward may hit the wheel house (5) and cause damage. Further, in order to solve the above problem, the phase of the hub may be adjusted in advance so that the hands (3a), (3b), and (3c) of the hand unit do not come into contact with the wheel house <5>. However, in the case of non-driven wheels, the hub rotates freely, so even if the phase is adjusted in advance, the phase may change, which may result in poor tire installation. Also, after the hand unit escapes after the tire is installed, the phase may change and the nut may not be able to be tightened. As described above, there are various problems in automatically assembling tires to the hub of non-drive vehicles. This invention particularly allows the tire to be attached to the hub of the non-driving wheel.
The purpose of the present invention is to provide an assembly method that allows for the installation of Il.

The tire assembly method according to the present invention involves detecting the position of the hub bolt by capturing an image of the hub bolt surface of the hub of the vehicle using two imaging cameras, and then detecting the position of the hub bolt using a hand unit. Attach the tire to the hub by aligning it with the hub bolt, and after installing, rotate the hand unit so that one hand of the hand unit is placed between the top of the tire and the wheel house, and then use the stopper to stop the tire from rotating. After blocking the tire, the hand is opened to release the hand unit from the tire, and then a nut is tightened on the hub bolt. [Operation] With the above assembly method, the position of the hub bolt is detected in a non-contact manner using a mirror image camera just before the tire is installed, and based on this detection data, the phase of the tire bolt holes is aligned and the tire is attached to the hub. Since it is attached to the front, there is no possibility of mis-attachment due to misalignment. In addition, after the tire is installed, the hand unit holding the tire is rotated and placed so that the hand and the wheel house do not interfere, and then the stopper prevents the rotation of the tire and allows the hand unit to escape. Nuts can be easily tightened without causing tires to shift. [Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 4.
