Description

[0001] Mounter of the heavy-duty tire [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a large tire mounter, and more particularly, to a large tire mounter mounted on a bus, a truck, etc., and a large tire mounter capable of automatically and quickly assembling the wheel.

Generally, a tire mounter is a device for assembling a tire and a wheel in a tire assembly line. When the center cone is lowered and the main lifter is raised when the tire is mounted, when the upper surface of the wheel is detected, the guide roller rotates to assemble the tire on the wheel .

More specifically, the mounting of the tire is carried out by horizontally mounting the wheel on the upper part of the rotary workbench, placing the tire on the upper part of the wheel, stretching the inner hole of the wheel to the outside with a certain force, The mounting arm unit is rotated and the bead portion of the tire is pressed from the upper portion so that the wheel is inserted into the through hole of the tire and assembled.

One example of such a technique is disclosed in Document 1 below.

The following Patent Document 1 discloses a rectangular frame-shaped support frame arranged to be in contact with the ground; A main frame fixedly installed on one upper surface of the support frame in a vertical direction; A arm elevating unit installed on the main frame so as to be able to be elevated and lowered to elevate the arm unit up and down; An arm rotating unit coupled to one side of the main frame to rotate the arm unit; An arm transfer unit coupled to a lower portion of the arm rotation unit to transfer the arm unit to the left and right; An arm unit coupled to a lower portion of the arm transfer unit and guiding the tire to be mounted on the bead surface of the wheel by pressing the tire simultaneously with rotation; A bead holder coupled to the main frame for pressing the upper surface of the tire so that the tire is inserted into the bead surface of the wheel when the tire is assembled; And a wheel clamp installed at an upper portion of the support frame and pressing and supporting the lower bead surface of the wheel when the wheel is transferred and seated.

The above-described conventional technology can work in the assembly of a tire and a wheel, as well as an existing size of a wheel, as well as a size (17 inches, 18 inches, etc.) more than that according to diversification of a tire specification.

However, the conventional technology as described above is a device for assembling a general tire and a wheel to be mounted on a passenger car or the like, and it is practically impossible to apply a large tire which is larger in size and heavier than a general tire. As such, there is no technology for a large-sized tire-mounted mounter.
