Description

  The present invention relates to a scuff resistance inspection method and inspection apparatus, and in particular, it is possible to easily check the scuff resistance of a resin material forming a golf ball, a ski boot, or a floor of a building. The present invention relates to an inspection method and an inspection apparatus for scuff resistance.

  For example, a resin for forming the outer skin of a golf ball or ski boots is required to have high scuff resistance and toughness that is difficult to be damaged even when a strong impact is applied. As such a resin, an ionomer resin in which an ethylene-methacrylic acid copolymer molecule is cross-linked with metal ions is suitable. For example, Mitsui-DuPont Polychemical Co., Ltd. provides the product under the trade name "Himiran". Has been.

  By the way, even if it is such a scuff-resistant resin material, if it is processed into a complicated shape like a golf ball, how much scuff resistance is actually demonstrated is resin It is difficult for the manufacturer to fully grasp.

  However, in recent years, in order to respond to various demands of processing manufacturers or end users who use resins, it is also required that manufacturers that provide resins can easily inspect scuff resistance.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a scuff resistance inspection method and an inspection apparatus that can be easily and easily inspected by anyone for examining scuff resistance.

The scuff resistance inspection method according to the present invention for achieving the above object is as follows:
A scuff resistance inspection method for inspecting the degree of scratches formed when rubbing the surface of a test object,
The test object is detachably mounted on a plate-like stage arranged in a substantially horizontal direction, and the inclination angle of the plate-like stage is adjusted by an inclination angle adjusting means arranged below, thereby The tilt angle is set to an arbitrary angle, the striking head is projected toward the upper surface of the plate-like stage, and the scuff resistance is inspected based on the scratch of the test object formed thereby. .

  According to the inspection method having such a configuration, for example, the scuff resistance can be examined while the plate is in a plate shape without changing the resin material to the product shape of the secondary processed product.

Moreover, the inspection apparatus according to the present invention includes:
A scuff resistance inspection device for inspecting the degree of scratches formed when rubbing the surface of a test object,
A plate-like stage in which the DUT is detachably set and the bottom surface of the one end is supported in a swingable manner in a cantilever state;
An inclination angle adjusting means that is disposed on the lower surface side of the plate stage and adjusts the inclination angle of the plate stage to an arbitrary angle by an extendable rod;
A striking force supply means for applying a force to the DUT by projecting a striking head from the substantially horizontal direction to the DUT set on the plate-like stage;
And a stopper means disposed in a direction in which the striking head of the striking force supply means protrudes.

  According to the inspection apparatus having such a configuration, the scuff resistance can be inspected with a compact structure. In addition, since the collision angle of the striking head with the object to be tested can be adjusted, the scuff resistance test can be performed in a posture that approximates the actual use state.

  Here, it is preferable that a protective cover for restricting inadvertent tilting of the hitting head to the upper side is provided on the upper side of the moving range of the hitting head.

  With such a configuration, even if the striking head collides with the device under test and the traveling direction is bent, it is possible to prevent an inadvertent tilting of the striking head in the upward direction.

  According to the scuffing resistance inspection method and inspection apparatus according to the present invention, the striking head can be caused to collide with the plate-shaped object to be tested at an angle, and is formed at the time of the collision. Scuff resistance can be examined based on the scratch.

  Therefore, for example, assuming that a golf ball is hit with a club, anyone can easily inspect the scuff resistance of the DUT.

  Further, according to the inspection method and the inspection apparatus of the present invention, it is possible to adjust the angle at which the impact force acts on the device under test by adjusting the angle of the tilt angle adjusting means.

  Further, by providing the protective cover, even if the striking direction of the striking head may be bent by an impact force, the movement can be restricted, and the safety is further ensured.

  Hereinafter, an embodiment of a scuff resistance inspection method and an inspection apparatus according to the present invention will be described with reference to the drawings.

  1 and 2 show an inspection apparatus for performing an inspection method according to an embodiment of the present invention.

  In this inspection apparatus 2, four angles 6 are erected on a base table 4 arranged at a predetermined height, and a flat plate-like stage 8 is cantilevered between the front and rear angles 6, 6 ′. Supported by the state. That is, the plate-like stage 8 has a support member 10 provided on a lower surface on the base end side facing the front angle 6 side, and a hinge 14 attached to a support block 12 erected from the fixed plate 11 of the base table 4. Thus, the plate-like stage 8 is supported so as to be swingable in the direction of the arrow AA ′ with the hinge 14 as a fulcrum.

  On the other hand, an inclination angle adjusting means 16 for adjusting the inclination angle α of the plate stage 8 is installed on the lower surface of the plate stage 8. The inclination angle adjusting means 16 adjusts the position of the roller 22 at the tip by causing the telescopic rod 18 to protrude from the air cylinder 20 by supplying compressed air. As shown in FIG. The plate-like stage 8 can be maintained at an inclination slightly higher than substantially horizontal, or the plate-like stage 8 can be inclined lower or higher than this, or can be adjusted to an arbitrary angle. Thus, the inclination angle α of the plate stage 8 is adjusted so as to be determined by the amount of compressed air supplied to the air cylinder 20.

  When a force equal to or higher than a predetermined pressure is applied to the plate stage 8 from above, the plate stage 8 is rotated in the direction of the arrow A ′ with the hinge 14 as a fulcrum.

  On the other hand, as a striking force supply means for projecting the striking head 24 in the length direction of the plate-like stage 8 on the opposite side of the air cylinder 20 across the column block 12 supporting the plate-like stage 8, An air cylinder 26 is provided. As shown in FIG. 2, the main air cylinder 26 has a height substantially equal to the height of the plate stage 28 so that the bottom surface 24a of the striking head 24 that expands and contracts slightly rubs the top surface of the plate stage 8. is set up. When the striking head 24 of the main air cylinder 26 is protruded by the supply of compressed air, for example, the tapered bottom surface 24a moves to the right in the figure while rubbing the surface of the plate-like stage 8. On the upper surface of the plate stage 8, a device under test 44 for inspecting scuff resistance is detachably installed at a predetermined position.

  A stopper means 28 is provided in front of the striking head 24 in the protruding direction.

  This stopper means 28 consists of an air cylinder, and the protrusion pressure to the arrow Y direction of the receiving member 30 is adjusted by adjusting the supply amount of compressed air.

  The striking head 24 projects from the main air cylinder 26 and abuts against the receiving member 30 of the stopper means 28, so that the striking head 24 is prevented from projecting more than necessary. In addition, as a surface material of the receiving member 30, a buffer material such as a synthetic resin is employed, so that an impact sound is absorbed and a moving range thereof is restricted.

  Furthermore, in this embodiment, a protective cover 32 made of a transparent body such as an acrylic plate is detachably installed on the upper surfaces of the four angles 6. By installing such a protective cover 32, even if the impact head 24 is inadvertently tilted upward due to an impact when the impact head 24 is protruded, it is tilted further. Is prevented and safety is ensured. In addition, when the protective cover 32 is a transparent body, the inside can be visually recognized from above.

  As described above, on the upper surface of the plate-like stage 8, as shown in FIG. 3, the positioning member 40 on which the scuff-resistant test object 44 is detachably set is installed. The positioning member 40 is made of, for example, a resin plate affixed to the upper surface of the plate stage 8, and a rectangular recess 42 is formed in a part thereof. And in this recess 42, the sheet-like to-be-tested object 44 for test | inspecting scuff resistance is detachably installed.

  The scuff resistance inspection apparatus 2 according to this embodiment is configured as described above, and the operation thereof will be described below.

  First, with such a scuff resistance inspection apparatus 2, for example, assuming that a resin material is used for a golf ball, it is possible to perform a scuff resistance inspection of the outer skin of the golf ball. In that case, the DUT 44 can be regarded as a golf ball skin and the striking head 24 can be regarded as a golf club. Therefore, if the striking head 24 is vigorously collided with the surface of the device under test 44, the bottom surface 24a rubs against the top surface of the device under test 44, so that the conditions are substantially the same as when the ball is hit with an actual club. can do. Thereby, the scuff resistance of the outer skin of the golf ball can be examined.

As described above, in order to inspect the scuff resistance, first, the supply amount of compressed air such as the inclination angle adjusting means 16, the main air cylinder 26, and the stopper means 28 is adjusted to an appropriate pressure. That is, the main air cylinder 26 is adjusted so that the striking head 24 protrudes at a speed of about 34 to 38 m / sec or more, assuming that the golf club actually swings the golf club. Moreover, the stopper means 28 is adjusted to a pressure that can weaken the momentum of the striking head 24 on the way. Further, the tilt angle adjusting means 16 is set to a slightly obtuse angle where the tilt angle α of the plate-like stage 8 exceeds 90 °.

In this embodiment, predetermined air is supplied to the main air cylinder 26 by simultaneously turning on the switches S ₁ and S ₂ from such a state. Then, the striking head 24 is projected, and the bottom surface 24a of the striking head 24 passes while contacting the surface of the device under test 44 set on the plate-like stage 8, thereby forming a scratch. After that, the striking head 24 rubbing the surface of the device under test 44 comes into contact with the receiving member 30 of the stopper means 28, and further protrusion is restricted. Thereafter, if the device under test 44 is removed from the plate-like stage 8, the scuff resistance test of the device under test 44 can be performed based on the scratches formed on the surface of the device under test 44. The inspection can be performed visually or can be determined by measuring the depth of the scratch. Furthermore, it can also be quantified.

  As described above, according to the inspection method and the inspection apparatus according to the present invention, the resin material having high hardness and high wear resistance can be obtained without processing into an actual complicated product shape like a golf ball. The scuff resistance can be easily inspected with the posture as it is.

  Therefore, anyone can easily inspect scuff resistance.

  As mentioned above, although one Example of this invention was described, this invention is not limited to the said Example at all.

  For example, in the above embodiment, the receiving member 30 of the stopper means 28 is provided on the same axis so as to face the traveling direction of the striking head 24 of the main air cylinder 26. Such a plate-like member may be provided, and this plate-like member may be provided on the free end side of the plate-like stage 28 depending from above. In short, the stopper means 28 may have any structure as long as the impact force of the striking head 24 can be absorbed in any form. Moreover, if the surrounding safety is ensured, the stopper means 28 can also omit this.

  In the above embodiment, the resin 44 that forms the outer skin of the golf ball is used as the device under test 44. Of course, the scuff resistance of the resin used for other purposes can also be inspected. Further, instead of the plate-like object to be tested 44, an actual golf ball can be placed on the plate-like stage 8 for testing.

  In this case, a change may be made such as opening a recess in the plate-like stage 8 and setting it so as not to move in the recess so that the ball does not move even when receiving an impact force from the striking head 24.

  The shape of the striking head 24 is not particularly limited and can be variously changed.

  For example, a narrow groove can be formed on the bottom surface 24 a of the striking head 24. Further, the bottom surface 24a can be formed in a circular arc shape instead of a tapered shape.

  Further, in the above-described embodiment, the test object 44 is tested as a golf ball, but for example, it can be tested as a ski shoe skin or a building floor.

In this way, in this embodiment, even if the resin material is processed into any product, before being processed into an actual product, the manufacturer of the resin material or anyone, The scuff resistance can be easily checked. In addition, the resin manufacturer can evaluate whether or not it meets the required mechanical characteristics. Therefore, it can contribute by product development.
