Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a display panel used in a device for correcting tire imbalance.

(Prior art) Vehicle tires must be perfectly balanced around the oblique axis, and if the tires are unbalanced, even a small amount of unbalance will cause a large centrifugal force when rotating at high speed. act. The centrifugal force not only prematurely wears out tires, but also poses a danger to driving operations, so it is used in a perfectly balanced manner. By the way, since the tires and the wheels on which the tires are mounted are not perfectly balanced when manufactured and assembled, the unbalance is corrected using a tire balancing device before mounting on a vehicle. A detailed explanation of the tire balancing device will be omitted here, but in general, a rotating main shaft is supported by two bearings, a tire is fixed to the tip of the rotating main shaft, and the tire is rotated to prevent imbalance. The centrifugal force generated due to the amount is measured at both of the bearings to detect the desired amount of unbalance. Since the unbalance amount is displayed separately for each position on the inside and outside of the tire, the displayed amount of weight is fixed at a predetermined location.

Incidentally, such tire imbalance correction work is carried out at gas stations, car repair shops, tire shops, etc., but most of it is done by services. This is a small amount of unbalance in the tire, and it is more like a service operation than a weight charge, so it is provided as a free service, and even if it is a leg, it is simply a small weight charge. If you have an old idea, you will end up calling it a service.

However, in reality, tire unbalance correction devices require technology; they not only need to be attached to the main rotating shaft of the device to rotate the tires, but also to accurately measure the wheel position, wheel width, and wheel diameter. Unless these values are set, the amount of unbalance cannot be detected correctly.

(Purpose of this invention) In this way, tire unbalance correction work must be done free of charge, regardless of the skill required, because it is not a visible product but has a strong service element. There is a problem. The present invention was devised to solve these problems, and provides a display panel that can display the amount of unbalance on the unbalance display panel and also display the charge at the same time.

(Configuration of the present invention) As described above, the tire imbalance correction device has the following features:
The rotating main shaft on which the wheel is attached is supported by two bearings, and the centrifugal force generated due to the amount of imbalance is measured by the bearings, and the configuration of the main body of the device is not limited. The present invention is directed to a display panel mounted on the device, and is constructed with the following features.

(1) The display panel displays the amount of unbalance of the tire separately for the inside and outside with numbers. Therefore, the amount of tire imbalance can be understood at a glance by looking at the displayed numbers.

(2) The display panel also shows the position of the wheel with tires attached to the rotating main shaft, the width of the wheel,
It also has an input section for setting the diameter of the wheel.

(3) Furthermore, a charge display section is formed, and the charge display is digitally displayed as a predetermined number in the same way as the unbalance amount. The charge display section includes a kind of basic charge display section for measuring the unbalance, a display section showing the weight charge for the inner unbalance amount, the weight charge for the outer unbalance amount, and sometimes the sum of the above charges. It forms a display section that displays. In addition, it is sometimes possible to display these charges by voice.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, one embodiment of a tire imbalance correction device display panel according to the present invention will be described in detail based on the drawings.

(Example) FIG. 1 shows an embodiment of a tire imbalance correction device display panel (hereinafter abbreviated as display panel) according to the present invention. In the figure, a cross section of the wheel is drawn on the left side, and rectangular frames are formed on the INNER side and OUTER side, respectively, and the amount of imbalance is displayed within the frames. By the way, the wheel is attached to the rotating main shaft and rotated at a constant rotation speed, but the outer diameter and width of the wheel,
Since the force acting on the bearing portion of the rotating main shaft changes depending on the mounting position on the rotating main shaft, an input section is provided for setting (inputting) these values.

In the display panel, the left volume 7 on the lower right side is a volume for inputting the position of the wheel from the bearing part, the center volume 8 inputs the width of the wheel, and the right volume 9 inputs the outer diameter of the wheel. These are for input. Therefore, the above three volumes 7, 8,
After inputting a predetermined value in step 9, the wheel with tire is fixed to the rotating main shaft. The wheel is the second
As shown in the figure, a specific example of the tire unbalance correction device is attached to the rotating main shaft 2 protruding from the side of the main body 1 via a coupling. displayed on display panel A.

By the way, the display panel A has a wheel.
Not only the unbalance amount on the INNER side and the OUTER side, but also the weight charges to be attached to the wheel in order to correct the unbalance amount are displayed at the same time. The upper right row shows the balance measurement fee, INNER side weight fee,
Display frames 4, 5, and 6 are formed where the wait fee on the OUTER side is displayed. Here, the balance measurement fee is a type of basic fee that is displayed regardless of the amount of weight attached, and the weight fee is a fee that is proportional to the weight of the weight itself. Furthermore, in addition to these three charge display frames 4, 5, and 6, a charge display frame for the total amount may be formed below.

As mentioned above, display panel A according to the present invention
The device is equipped with an input section for setting the position, width, and outer diameter of the wheel attached to the rotating main shaft of the device, an unbalance amount display section, and a charge display section. You can get an effect like this.

(Effects) (1) Since the display panel according to the present invention allows the amount of tire imbalance to be seen at a glance,
It is possible to obtain a perfectly balanced tire that is satisfactory not only to workers but also to general users.

(2) In addition, since the fee is also displayed on the display panel, it becomes easier to bill general customers for the specified fee. In other words, it is possible to make customers understand the fee (commission) required for tire imbalance correction work, which is more of a technical service element than a product provision, and it is very convenient to display the amount of imbalance of the tire on the same panel.
