Japanese Patent No. 5795134

The known prior art has the following problems to be solved.
Processed floor materials made of foamed plastic are often used for building insulation floors and walls. Known foamed plastics include, for example, beaded polystyrene foam, extruded polystyrene foam, polyethylene foam, phenol foam, and rigid urethane foam.

  These face materials use heat rays or are cut with a cutter knife as shown in Patent Document 1 above. However, the foam plastic face material has a problem that the cutting resistance increases as the thickness increases, and the cut surface becomes rough and does not become flat. An electric saw can work efficiently, but there is a problem that a large amount of chips are generated. Moreover, when it cut | disconnects with a heat ray, there exists a problem that gas is emitted by a chemical reaction. The present invention has been made to solve the above problems.

It is a perspective view which shows the principal part of the cutting device of the foam plastic surface material of this invention. It is a perspective view which shows the whole structure of the cutting device of this invention. It is an apparatus principal part side view for demonstrating the function of an angle adjustment mechanism. It is explanatory drawing of the effective length of a cutting blade.

  Hereinafter, embodiments of the present invention will be described in detail for each example.

FIG. 1 is a perspective view showing a main part of a cutting device for foamed plastic face material according to the present invention, and FIG. 1A is a specific perspective view of the cutting blade driving device, and FIG. 1B is a side view at the time of operation thereof.
As shown in FIG. 2, the cutting device 12 of the present invention includes a positioning device 18 that determines the processing position of the foam plastic face material 16 on the work table 14, and the positioned face material 16 on the work table 14. And a clamping device 20 that is fixed by This is the same as the apparatus introduced in Patent Document 1.

  That is, the face material 16 is carried onto the processing table 14 and positioned on the processing table 14 by the positioning device 18. Thereafter, the face material 16 is pressed onto the work table 14 and fixed by some clamping devices 20. In this state, the cutting blade driving device 24 is driven to cut the face material 16 with the cutting blade 22.

  In order to cut out the product from the face material 16, a commercially available cutter knife type cutting blade 22 can be used. The cutter knife type cutting blade 22 that is generally marketed can start to be used from the end portion, and can be used by gradually discarding the used portion to maintain the sharpness. The present invention uses this function.

  As shown in FIG. 2, the cutting blade driving device 24 supports one end of the cutting blade 22 and moves the cutting blade 22 in the cutting direction while reciprocating the cutting blade 22 in the longitudinal direction. FIG. 1 specifically shows the mechanism of each part of the cutting blade driving device 24.

  The cutting blade drive device 24 includes a support mechanism 30, an angle adjustment mechanism 32, and a reciprocation drive mechanism 28. The support mechanism 30 has a structure in which one end of the cutter knife-type cutting blade 22 is grasped and supported so as to be replaceable. Specifically, as shown in the drawing, the cutting blade 22 is sandwiched between the metal fittings 34, and the bolts 36 are passed through the knife holes 38 and fixed. The fixed portion of the cutting blade 22 can be replaced with any other mechanical structure.

  The angle adjusting mechanism 32 supports the back surface of the cutting blade driving device 24 and has a function of adjusting the inclination angle of the cutting blade 22 with respect to the surface of the processing table 14. In this example, the angle adjustment mechanism 32 is integrated with the travel mechanism 40. The traveling mechanism 40 has a function of traveling along a rail laid in parallel to the cutting direction. The arrangement and structure of the traveling mechanism 40 and the rail 42 can be freely changed as long as they have similar functions.

  The angle adjustment mechanism 32 selects the inclination angle of the cutting blade 22 together with the cutting blade driving device 24 to a designated angle. The reciprocating drive mechanism 28 has a structure for reciprocating the cutting blade 22 in parallel with the longitudinal direction thereof. For example, this function can be realized by a crank or cam mechanism housed in the reciprocating drive mechanism 28.

  The cutting blade 22 moves along the work table 14 while cutting the face material 16, but the other end of the cutting blade 22 may vibrate in a direction perpendicular to the cutting direction during the movement. Therefore, the steadying device 26 is configured by a groove disposed so as to sandwich the other end of the cutting blade 22 along the work table 14. Thereby, the vibration is suppressed.

  Since the above apparatus cuts the face material 16 while reciprocating the cutter knife type cutting blade 22 in the longitudinal direction, friction with the face material is generated in the longitudinal direction of the cutting blade 22, and the face material is removed at the cutting front. Generates a separating force and improves the cutting force. The cutting front means a linear part where the cutting edge of the cutting blade 22 contacts the face material. Thereby, a beautiful cut surface can be formed on the face material 16.

FIG. 3 is a side view of the main part of the apparatus for explaining the function of the angle adjustment mechanism 32.
As shown in the figure, the cutting blade driving device 24 supports the cutting blade 22 at an angle a set in advance with respect to the surface of the processing table 14 in accordance with the thickness of the face material 16. For example, when the angle between the surface of the work table 14 and the line facing the reciprocating direction A is a, the angle a is set smaller as the thickness of the face material 16 is thinner. Thereby, a certain long range of a cutting blade can be used uniformly. Therefore, there is an effect that the life of the cutting blade 22 is extended.

FIG. 4 is an explanatory diagram of the effective length of the cutting blade 22.
As shown in FIG. 4, the commercially available cutting blade 22 is divided into three places, for example, b1, b2, b3 from the tip, and the used part is always discarded and a new blade is used. Can be cut. The length of this one section is called an effective length.

The reciprocating drive mechanism 28 reciprocates the support mechanism 30 with an amplitude corresponding to the effective length with reference to the surface of the processing table 14. That is, the effective length can be determined at a plurality of locations, and used for cutting in the order of b1, b2, and b3 for each section, and used portions can be discarded. In addition, since the entire section is used uniformly by reciprocating motion, sharpness can be maintained for a certain period.

  The effect of the face material made of foamed plastic having a thickness of about 30 mm to 100 mm was verified using the above-described apparatus. It was found that the amplitude of the reciprocating motion of the cutting blade 22 is in the range of 1 mm or more and 10 mm or less, and that the cutting blade can be used effectively and universally and that a good cutting surface can be obtained. When the amplitude is less than 1 mm, the effect of using the cutting blade uniformly is reduced and the consumption of the cutting blade becomes severe. When the amplitude exceeds 10 mm, heat generation due to friction with the cut surface of the face material has an adverse effect.

  From the above, it has been found that a face material close to the minimum thickness has an amplitude of about 1 mm to 3 mm, and a face material close to the maximum thickness can have a good cut surface when the amplitude is 5 mm to 10 mm. Further, it was found that the frequency of reciprocating motion is preferably in the range of 1000 times to 7000 times per minute. When the frequency is less than 1000 times, the cutting speed is slow compared to the case where the frequency is more than 1000 times, resulting in poor productivity. On the other hand, when the frequency exceeded 7000 times, it was found that the workability was adversely affected by noise.
