Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a tire attaching / detaching apparatus, and more particularly, to a tire attaching / detaching apparatus capable of immediately checking a balance state with a tire mounted.

[0002]

[Prior art]

 When attaching a tire to a wheel, a tire attachment / detachment device is generally used to improve the efficiency of tire attachment / detachment work. FIG. 2 shows a conventional tire attaching / detaching apparatus, in which 1 is an apparatus main body, 2 is a rotary table, 3 is a tire claw, 4 is a mount roller, 5 is a wheel, and 6 is a tire. The figure shows a state in which the tire 6 is mounted on the wheel 5. When mounting the tire, the wheel 5 is fixed to the rotary table 2 via the chuck claws 7, 7, and the bead of the tire 6 is mounted on the wheel 5. Fit it. The tire claw 3 is used for fitting the bead, and the tire 6 and the wheel 5 are rotated together with the table 2 in a state where the bead is locked to the tire claw 3.

[0003] After the lower bead is fitted, the upper bead is fitted to complete the mounting of the tire. However, in the case of a flat tire in which it is difficult to fit the upper bead using only the tire claw 3, the mounting roller 4 is used. Is used. That is, the upper surface of the tire is fitted while being pressed by the mount roller 4. This tire attaching / detaching device has a structure in which the positions of the tire pawl 3 and the mount roller 4 can be adjusted according to the size of the tire.

The tire 6 mounted on the wheel 5 is filled with air at a predetermined pressure, and thereafter the tire balance is measured. The wheels 5 and the tires 6 are weight-balanced about the axle, but a slight imbalance, not 100%, can hinder the operation of the car and sometimes lead to accidents. Therefore, the tire is rotated at high speed, the unbalance is measured, and a weight is attached to an appropriate place so that the tire is balanced.

[0005] Conventionally, a tire balancer device is used to measure the balance state of the tire 6 mounted on the wheel 5, but the tire 6 mounted on the wheel 5 is transported to the tire balancer by a tire attaching / detaching device, and measurement is not performed. In spite of the fact that the installation of tires and the measurement of tire balance are a series of tasks that cannot be cut, workability is poor because the tasks are separated. Separately installing the tire mounting and dismounting device and the tire balancer device in a narrow work area also poses a space problem.

[0006]

[Problems to be solved by the present invention]

 As described above, the conventional tire attaching / detaching device and the tire balancer device have the above-mentioned problems. The problem to be solved by the present invention is this problem, and an object of the present invention is to provide a tire attaching / detaching apparatus with a balancer which improves workability and does not take up space.

[0007]

[Means for Solving the Problems]

 The tire attachment / detachment device of the present invention has a tire balancer function, and a tire balancer device is attached to a part of the tire attachment / detachment device. The tire balancer device can be simple and manually rotated, or it can be automatically rotated with a motor. Therefore, the tire mounted on the wheel is measured by the balancer using the same machine as it is, and the necessary weight is fixed.

[0008]

[Embodiment of the invention]

 When the tire attaching / detaching device of the present invention is applied to a small tire such as a passenger car as shown in FIG. 2, the tire balancer device is attached to the main body. Although the specific structure of the tire attaching / detaching device is not particularly limited, a mount roller may be attached in addition to the tire claw. The position of tire pawls and mount rollers can be changed according to the size of the tire as before. Also, in a tire mounting and dismounting device for large tires such as trucks, a tire balancer device can be provided on a table that stands upright from the base. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0009]

【Example】

 FIG. 1 shows an embodiment of a tire mounting / dismounting device with a balancer according to the present invention, and a balancer device 11 is mounted on the main body 1. As described with reference to FIG. 2, the tire attaching / detaching apparatus includes a horizontally arranged rotary table 2, a tire claw 3 which is engaged with a tire bead and detaches the tire 6, and a mount roller 4 which presses the upper surface of the tire. The balancer device 11 has a rotating main shaft 12 and extends horizontally from the main body 13.

The rotating main shaft 12 is supported by bearings provided at predetermined intervals in the main body 13, and centrifugal force generated from unbalance between tires and wheels acts on the bearings, and forces acting on these bearings Is measured. Since the balancer device 11 is manually operated, it rotates by hand the tire 6 attached to the rotating main shaft 12, detects the rotational speed, and calculates the unbalance amount from the force acting on the bearing by centrifugal force.

The display panel 14 of the balancer device 11 displays an unbalanced portion in addition to the unbalance amount. Therefore, the weight is fixed at the displayed location. A plurality of small recesses are formed in the table 15 of the main body, and these recesses accommodate various weights. The measurement is performed again with the specified weight attached to the specified location, and the measurement is completed if the unbalance amount is within the allowable range.

In the embodiment shown in FIG. 1, the rotating main shaft 12 of the balancer device is manually rotated, but may be provided with a motor. Especially when measuring the balance of large tires, motors are often driven because they cannot be rotated at high speed by hand. As described above, the tire attaching / detaching device with a balancer according to the present invention has a tire balancer function, and the following effects can be obtained.

[0013]

[Effect of the invention]

 Since the tire attachment / detachment device of the present invention has a tire balancer device, it is possible to mount the tire on the wheel and at the same time measure the balance with the same machine. Since it is the same machine, there is no need to carry the tire to the measuring device, and a series of operations from tire mounting to balance measurement can be performed efficiently. By incorporating the balancer device into a part of the tire attaching / detaching device, the working space can be reduced as compared with a case where two units are separately installed.
