On the other hand, in the present invention, when the ball (B) is discharged from the discharge port (121) to insert the ball (B) into the space between the outer ring (OR) and the inner ring (IR) forming the interspace by pressing and fixing , Excessive pressure may be applied to fix the outer ring OR and the inner ring IR, which may result in damage to the outer ring OR and the inner ring IR. In particular, this may be more prominent when the outer ring OR and the inner ring IR to be processed are soft.

Accordingly, the present invention provides a limiting means (R) for reinforcing the fixing by limiting the movement of the outer ring (OR) and the inner ring (IR) back and forth so that the force to pressurize the outer ring (OR) and the inner ring (IR) does not act excessively. It is characterized in that it may further include.

The above-described limiting means (R) is provided at the movement limiting position of the outer ring (OR) and the inner ring (IR) to limit the movement of the outer ring (OR) and the inner ring (IR), the receiver (R2), on the moving surface (on the path) And a trigger R1 provided in and pressed by the outer ring OR and the inner ring IR, and an actuator R3 for raising and lowering the receiver R2 by a depressed operation of the trigger R1.

First, looking at the trigger R1, the trigger R1 is provided on a moving surface (on the path), and the trigger R1 is exposed above the moving surface, and the outer ring OR and the inner ring IR And an exposed upper portion having an upward inclination along the moving direction of (hereinafter referred to as a moving direction), a built-in lower part connected to a lower portion of the exposed upper part and built into a lower side of the moving surface, and a contact part formed at a lower end of the built-in lower part.

First, the exposed upper portion is exposed on the moving surface, and the outer ring OR and the inner ring IR press the exposed upper portion to contact the contact portion and the terminal portion to operate the limiting means R. .

And when the outer ring (OR) and the inner ring (IR) press the exposed upper portion, the exposed upper portion descends into the inside of the moving surface, and the outer ring (OR) and the inner ring (IR) pressurize the exposed upper portion easily. In order to do so, the exposed upper portion must have an upward slope in the moving direction of the outer ring OR and the inner ring IR, and the height of the entrance of the upward slope must be equal to or lower than the height of the moving surface.

In addition, when the pressure of the outer ring OR and the inner ring IR is released at the lower end of the trigger R1, a predetermined return means such as an elastic body may be provided to separate the contact portion and the terminal portion again, and such a return means It is not specifically limited to any one form.

And in order for the trigger R1 to move toward the terminal portion of the actuator R3 and generate an electrical signal completely without contact failure, first, the outer ring OR and the inner ring IR must be easy to initially enter the trigger R1 side. Secondly, after the initial entry, it is necessary to secure an appropriate vertical displacement value of the trigger R1.

Accordingly, as shown in FIG. 9, the exposed upper portion of the trigger R1 is in line contact with the outer ring OR and the inner ring IR, and the inclination point increasing portion R11 gradually increases in the moving direction, and the It includes an inclination point reduction part R12 extending in the moving direction from the inclination point increasing part R11 and decreasing inclination along the moving direction, and the trigger R1 is in the moving direction from the inclined point decreasing part R12. It further includes an upper protrusion R13 extending and protruding upward, and the upper protrusion R13 has the same inclined structure as a combination of the inclined point increasing portion R11 and the inclined point reducing portion R12.

First, here, the moving direction means a moving direction of the outer ring OR and the inner ring IR on the path.

In addition, the inclination point increase R11 has a shape of an exponential function in which the inclination starts with a slope of 0 and gradually increases, and the slope of the slope increases gradually, so that the outer ring OR and the inner ring IR The initial entry can be smoothly performed toward the trigger R1.

And the outer ring (OR) and the inner ring (IR) passes through the inflection point and enters toward the inclination point reduction portion R12, the inclination point reduction portion R12 is in a form in which the steep slope gradually decreases, and the metal member ( When M) presses the inclination decay portion R12 in the vertical direction, the trigger R1 can smoothly move toward the terminal portion of the actuator R3.

In addition, the ratio of the height h1 of the inclined point increasing portion R11 and the height h2 of the inclined point reducing portion R12 is preferable to correspond to 1:3 as a result of various experiments, through which the outer ring OR and the inner ring IR This is because the vertical displacement movement width of the trigger R1 can be maximized while securing the ease of initial entry of the trigger R1.

And after the outer ring (OR) and the inner ring (IR) pass through the inclination point reduction portion (R12), the upper protrusion (R13) enters the upper protrusion (R13), the inclination point increasing portion (R11) and the inclination This corresponds to a configuration including all of the inclined shapes of the tapered portion R12. Through this, it is possible to obtain an effect of securing a large vertical displacement movement width of the trigger R1 and ease of entry into the exposed upper portion.

Next, after the outer ring OR and the inner ring IR have passed the trigger R1, the receiver R2 provided at the movement limiting position of the outer ring OR and the inner ring IR is the actuator It moves upwardly to the upper part of the moving surface by (R3).

That is, the receiver R2 is concealed inside the moving surface based on the moving surface, and then moves upwardly to the upper part of the moving surface by the actuator R3, so that the outer ring OR and the inner ring IR You control the movement before and after. In addition, the receiver R2 may be provided on the moving surface, or may be separately provided at a position spaced apart from the moving surface. That is, it may be provided in a spaced position having the same height as the moving surface.

And here, the movement limit position refers to a position located behind the trigger (R1) based on the movement direction of the outer ring (OR) and the inner ring (IR), and obviously, the outer ring (OR) and the inner ring (IR) move. It must be a position in which the receiver R2 can be fully raised by the lifting means before arriving at the restricted position.

In addition, the receiver R2 includes a magnetic body R20 embedded therein, a vertical portion disposed perpendicular to the moving direction, and a parallel portion disposed parallel to the moving direction, in contact with the outer ring OR and the inner ring IR. Including an elastic receiver (R21) forming a limiting portion (R22), the elastic receiver (R21) is a second vertical portion extending upward from the parallel portion and a second horizontally extending from the upper end of the second vertical portion It further includes a second limiting part R23 formed by the parallel part and having a larger upper and lower width than the limiting part R22.

First, since the magnetic body R20 is located at the center of the receiver R2, it is possible to stably support the center of gravity of the outer ring OR and the inner ring IR.

In addition, the elastic receiver R21 is made of a material having elasticity in order to stably absorb the impact caused by collision with the outer ring OR and the inner ring IR, and may include various elastic polymers such as latex and urethane.

In addition, the elastic receiver R21 includes an n-th limiting part such as a limiting part R22, a second limiting part R23, and a third limiting part R24, as described above, so that the outer ring OR and the inner ring ( According to the height of IR), the corresponding n-th limiting portion can stably support the front and upper surfaces of the metal member M.

Next, the actuator R3 is a terminal part spaced apart from the lower part of the contact part by the height of the exposed upper part, and one end is connected to the terminal part to transmit a driving signal by contacting the contact part and the terminal part. And an elevating means connected to the other end of the signal transmission unit and elevating the receiver R2 by the driving signal.

First, the terminal portion generates an electrical signal by contact with the contact portion of the trigger R1, and generation of the electrical signal by such contact may refer to a known operating principle of a touch switch.

Then, the signal transmission unit transmits the generated electrical signal to the lifting means so that the lifting means raises the receiver R2 concealed inside the moving surface to the upper part of the moving surface.

And these lifting means can be implemented in various forms, such as a cylinder method, a crank method, a hoisting machine method, a lift method, etc., and specific implementations thereof are outside the scope of the present invention, and reference to the general common knowledge or known techniques of a person skilled in the art I can.

The present invention described above with reference to the accompanying drawings can be variously modified and changed by a person skilled in the art, and such modifications and changes should be construed as being included in the scope of the present invention.
