Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire supply truck for transporting tires and mounting them on a vehicle.

[0002]

2. Description of the Related Art For example, in an assembly line for producing a small amount of vehicles such as automobiles, most steps are manually performed by workers. Therefore, automated equipment such as a normal assembly line is not adopted, and tire installation work is a manual process.

Normally, four tires (one for each tire) are placed on the carriage, and the operator takes out the tires one by one from the carriage, and then the tire The tire is attached by aligning the wheel hole of the tire with the wheel bolt portion of the vehicle. At this time, since the tire is a relatively heavy object, the work of taking out the tire from the carriage is a considerable burden on the operator.

Therefore, for example, Japanese Laid-Open Patent Publication No. 10-32424.
As disclosed in Japanese Patent Publication No. 7, as well as having a pair of front and rear vertical tire wheel fixed support frame portions, a base frame provided with a plurality of wheels, and a pair provided between the pair of support frame portions, There is known a tire wheel carrier cart including a tire wheel payout member pivotally attached to one end of the left and right side ends of the base frame, and an operation arm portion provided upright on the payout member. . Therefore, by swinging the operation arm portion downward to swing the tire wheel paying-out member, the tire wheel placed on the tire wheel paying-out member is paid out from the tire wheel transport carriage.

[0005]

However, in the above-mentioned prior art, although the tire can be easily discharged after it has been conveyed to a desired location via the conveyance carriage, the tire is mounted on the vehicle. The work becomes complicated and labor-intensive. That is, the operator needs to lift the tire discharged from the carrier to align the wheel hole of the tire with the wheel bolt portion of the vehicle. At that time, the operator must handle the tire, which is a heavy object, in an unreasonable posture, which poses a problem that a heavy burden is imposed on the operator.

In addition, recently, aluminum wheels have become widespread, and if the aluminum bolts are rubbed with the wheel bolts at the time of mounting a tire, the aluminum wheels are easily damaged and relatively many defective products are produced. A problem has been pointed out.

The present invention solves this kind of problem, and provides a tire that allows a tire to be placed and transported to a predetermined attachment position and the tire to be easily and quickly attached to a vehicle. The purpose is to provide a trolley.

[0008]

In the tire supply truck according to the present invention, one end of a holding member is rotatably supported by a movable frame member, and the other end of the holding member has a height. It is configured to be adjustable. The holding member is provided with a roller member that rotatably mounts the tire in a posture for mounting the tire on the vehicle.

Therefore, for example, after the tire is transferred from the loading carriage to the tire supplying carriage, the tire can be easily transported to a predetermined mounting position via the caster provided on the frame member. . Then, the tire mounted on the roller member is aligned with the height of the wheel bolt portion, which is a tire mounting portion of the vehicle, by adjusting the height of the holding member. Further, the tire is rotatable with respect to the roller member, and the wheel hole of the tire is rotationally adjusted according to the angular position of the wheel bolt portion of the vehicle.

Then, the tire is moved to the vehicle side under the guiding action of the holding member, so that the tire can be easily and quickly attached to the vehicle. In particular, compared to the conventional work in which the operator lifts the tire and attaches it to the vehicle, the burden on the operator is significantly reduced, and the work efficiency can be improved.

Further, the roller member is provided with a pair of roller members whose mutual spacing can be adjusted according to the size of the tire. For this reason, it can be effectively used for various tires having different dimensions, which is excellent in versatility and economical.

Furthermore, the height of the holding member can be adjusted via an elastic member, such as a spring member, arranged at the other end of the holding member. Therefore, the height adjusting mechanism of the holding member is easily simplified, which is economical.
