Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for manufacturing a gradient plate having a rectangular top surface inclined in a diagonal direction or a diagonal direction. The present invention relates to a method and an apparatus for manufacturing a gradient plate that is cut and processed on a desired inclined surface by a hot wire or the like.

[0002]

2. Description of the Related Art A gradient plate made of a synthetic resin foam having an arbitrary inclined surface is used as a base material for forming a ground surface by laying a large number when laying a sloped floor surface, and for building or the like. It can be used as a packaging material for model members and various home appliances.

For example, regarding the construction of a floor with a slope such as a veranda or a rooftop, there is known a construction technique called a dry construction method using a synthetic resin foam plate material (gradient plate for foundation) as a foundation. In other words, the dry method is to lay a large number of slope plates for the groundwork and to lay a waterproof sheet on it to form the groundwork of the sloped floor surface, without performing mortar work to form the groundwork In this way, the weight and the construction period are reduced.

[0004] Generally, a gradient plate for a base has an outer shape of a long plate, and a top surface is inclined in a direction opposite to the longitudinal direction to form a forward inclined surface (a so-called two-dimensional sloper). For example, as disclosed in Japanese Patent No. 2987790, there is a diagonal inclined surface (so-called three-dimensional sloper). In other words, most parts of the floor to be constructed will be lined with forward slope plates. However, as disclosed in the above-mentioned publication, when a drain is provided below the water, an oblique slope is provided below the water. A gradient plate is provided to obtain the proper slope.

On the other hand, in the case of a gradient plate for groundwork or the like, if the inclination of the top surface is a forward gradient in which the inclination is in the opposite direction of the longitudinal direction, the inclined surface is flat. Unless the height of the corner is set properly, it will not be flat. And, for example, in the product setting of the slope plate for the oblique slope, generally, the height of the two corners corresponding to both ends of the long side is set to be the same, and a setting is adopted in which one of the corners is inclined diagonally from the other corner. The inclination setting cannot be realized with a flat surface, and the inclination toward the diagonal of the lowest height is a concave surface that becomes a valley line, or the inclination toward the opposite diagonal is a convex surface that becomes a mountain line. Face.

Conventionally, in manufacturing such a gradient plate, a method of cutting a long plate-shaped raw material formed by foaming a synthetic resin with a hot wire has been adopted.

[0007] For example, in a small amount of production, the rectangular bulk 100 of height H ₀ as shown in FIG. 14 (a), the height of the two angles corresponding to both ends of the longitudinal sides H _1, the remaining two Gradient plate 1 with H ₂ and H ₃ (H ₁ > H ₂ > H ₃ )
When cutting 01, a pair of profile plates 102a and 102 projecting the inclination of the top surface as shown in FIG.
b is attached to both side surfaces of the original body 100, and these profile plates are cut along the hot wire 103 to be formed and processed.

[0008]

However, in the manufacturing process using the above-mentioned conventional profile plate, it is troublesome to attach the profile plate to the original body one by one, and the process is performed one by one. Not suitable for mass production. In addition, since the nichrome wire is cut while being pressed against the profile plate, the nichrome wire and the profile plate are greatly consumed, which is not suitable for mass production.

Further, as described above, in the product setting of the inclined plate having the inclined surface, the inclination setting of the top surface cannot be realized by a single plane, and it is difficult to accurately process the inclined surface because it is a three-dimensional surface. Therefore, a manufacturing method and a manufacturing apparatus capable of performing appropriate processing have been desired.

[0010] The present invention has been made in view of such circumstances, and can be easily and easily processed.
It is an object of the present invention to provide a method and an apparatus for manufacturing a gradient plate which is capable of appropriately processing an inclined plate having an inclined surface having a three-dimensional surface and suitable for mass production.

That is, the method for manufacturing a gradient plate of the present invention comprises:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a method and an apparatus for manufacturing a gradient plate according to the present invention will be described with reference to the accompanying drawings, but the present invention is not limited to these examples.

(First Embodiment) FIG. 1 is a perspective view showing an apparatus for manufacturing a gradient plate. FIG. 2 is a side view of the manufacturing apparatus, and FIG. 3 is an enlarged side view of the support means of FIG.

The manufacturing apparatus 1 manufactures a gradient plate for a base in which a rectangular top surface is inclined diagonally or diagonally, and includes a support plate 3, a heating wire 4, a feed table 5, and a drive motor 6. Are provided on the base 10.

The support plate 3 is configured such that a plate-shaped or block-shaped original body 20 formed by foaming a synthetic resin is supported in a predetermined inclined posture by an inclined spacer 30 described later, and is mounted on the feed table 5. is there.

The base 10 is a box made of a frame material, and has columns 11, 11 provided in the center of the short sides. The heating wire 4 is stretched horizontally between the struts 11 and 11 to constitute a cutting means. The heating wire 4 is stretched vertically and a plurality of the heating wires 4 are attached so that the height positions thereof can be changed and can be adjusted appropriately. Take the configuration.

The heating wire 4 is a nichrome wire or the like that generates heat when energized, and the voltage is varied by a sliderack 40 attached to the base 10 to appropriately adjust the heating value.

A plurality of guide rails 12 are provided on the upper surface of the base 10 in a direction crossing the heating wire 4. The feed table 5 is mounted on the guide rails 12, 12 via a plurality of rollers 13, and is horizontally movable in a guide direction of the guide rails 12, that is, in a direction toward the heating wire 4.

The drive motor 6 is disposed below the guide rail 12, is linked to the feed table 5 via a transmission mechanism (not shown), and drives the feed table 5 by driving the same. Then, the drive motor 6 is configured to perform a so-called inverter control by controlling the rotation by a control unit 60 disposed adjacently. Thereby, the feed position of the feed table 5 can be controlled with high accuracy.

As shown in FIG. 3, a plurality of inclined spacers 30 are arranged on the upper surface of the support plate 3, and the original bodies 20 are arranged on each inclined spacer 30, and the original bodies 20 are arranged in multiple rows in each row. And a weight 7 is placed thereon and weighted thereon. The support plate 3 is set to be attached to the feed table 5 in a direction in which the longitudinal direction of the original body 20 placed on the support plate 3 faces the heating wire 4.

FIG. 4 is a perspective view showing an example of the base gradient plate. The gradient plate 2 for the base shown in FIG.
Manufacturing the gradient plate 2 with the top surface inclined in a diagonal direction will be described as an example.

That is, in the gradient plate 2, the heights h1 of the two corners at both ends of the longitudinal side are made equal, and the heights of the remaining two corners are h2 and h3 (h1>h2> h3), respectively. Take a setting to incline diagonally from the corner Therefore,
The inclination angle R on the end face on the diagonal minimum height h3 side becomes the maximum inclination, and the inclination angle S on the end face on the intermediate height h2 side becomes the minimum inclination.

Therefore, as shown in FIG. 5, one end of the inclined spacer 30 provided on the support plate 3 has an inclination angle R.
Is obtained, and the other end is set to a height at which the inclination angle S is obtained.

That is, by arranging the original bodies 20 on the inclined spacers 30, placing the weights 7 thereon and applying weight thereto, the original bodies 20 can assume an inclined posture corresponding to the inclination of the gradient plate 2. it can.

Here, as shown in FIG. 6, the height position of the heating wire 4 is adjusted to a position where the product height h1 is obtained, and the feed table 5 is fed and moved, so that cutting can be performed on a predetermined inclined surface. . In other words, the end face on the inclination angle R side is cut to obtain the minimum height h3, and the other end face on the inclination angle S side is the intermediate height h2.
To obtain an inclined surface. FIG. 6A shows a cutting state on the end surface on the inclination angle R side (minimum height h3 side), and FIG. 6B shows a cutting state on the end surface on the inclination angle S side (intermediate height h2 side). The state is shown.

Strictly speaking, the original bodies 20 arranged on the inclined spacers 30 are not in a stable state but in a state where one corner is floating. And this body 2
By placing the weight 7 on the vicinity of the center of 0 and applying weight, the original body 20 is curved in a downwardly convex state and becomes a stable state. When the original body 20 curved in a downwardly convex state is cut horizontally by the heating wire 4, the cut surface is a horizontal plane when the weight 7 is placed, but is more curved when the weight 7 is removed. As a result, the cut surface on the product side becomes an inclined surface that is convex upward.

When the weight 7 is placed near the end face on the inclination angle R side and the end face on the inclination angle S side of the original body 20 and weighted, the original body 20 curves upwardly. It becomes a stable state. In such a case, the cut surface on the product side is an inclined surface that is convex downward.

However, in any of the above cases, the top surface of the product is inclined diagonally, and it is still a three-dimensional sloper having an obliquely inclined surface.

As described above, the manufacture of the base gradient plate 2 is performed as follows.
The long plate-shaped original body 20 formed by foaming a synthetic resin is supported on the support plate 3 so as to have an inclined posture corresponding to the inclination of the top surface of the product, and the hot wire 4 is spread horizontally and the hot wire 4 is spread. By adjusting the height position and moving the support plate 3 in the horizontal direction, the inclination of the top surface of the product can be obtained, and processing can be appropriately performed even on an inclined plate having an inclined surface having a three-dimensional surface.

In the case of this example, the original material 20 on the support plate 3
Since the long side faces the heating wire 4 and the longitudinal side is cut and processed, the processing time can be shortened, and the original bodies 20 which are stacked in many stages and arranged in many rows are collectively processed. In addition, mass production can be performed efficiently.

The support member (support plate 3, inclined spacer 30, and weight 7) determines the inclination of the original body 20, and the processing conditions such as the feed speed of the feed table 5 and the heating value of the heating wire 4 are set in advance. So the worker is the original 2
It is sufficient to simply operate the start switch with 0 mounted at a predetermined position, and it is easy to manufacture without any skill. still,
The feed rate of the feed table 5 and the calorific value of the heating wire 4 can be appropriately set according to the density of the raw material. For example, as the density is higher, the feed rate is set lower or the calorific value is set larger.

That is, in the manufacturing apparatus 1, the processing can be easily performed without any trouble, and the inclined plate having an inclined surface having a three-dimensional surface can be appropriately processed and suitable for mass production.

In the present embodiment, the rear side (the rear side with respect to the feed direction) of the original body 20 is placed on the inclined spacer 30 as shown in FIG. 5, but as shown in FIG. 20
By placing the front side (with respect to the feed direction) on the inclined spacer 30, the original body can be cut by reversing the left and right sides with respect to the feed direction. When the left and right sides of the original body are reversed in this way, the inclination posture of the original body 20 is reversed left and right with respect to the heat ray 4. In this state, the height position of the heating wire 4 is set to the product height h.
When the feed table 5 is moved and cut by adjusting to a position where 1 can be obtained, as shown in FIG. 8, an inclined surface symmetrical to that shown in FIG. 4 can be obtained as shown in FIG. That is, a symmetrical product can be easily processed.

In general, a sloped floor such as a veranda often adopts a setting in which design conditions are such that a ridge is provided and the slope is distributed to the left and right. Is required. Therefore, it is extremely efficient that two types of processing can be performed only by changing the mounting method of the original body 20 as described above without changing the configuration of the support means, and the productivity can be improved.

In the above description, a heating wire is used as the cutting means, but a cutting tooth such as a saw or a knife can be used instead of the heating wire. In addition, instead of moving the support plate horizontally during cutting, the heating wire (or the above-mentioned cutting teeth) may be moved horizontally. In short, the support plate or the heating wire (or the above-mentioned cutting teeth) is relatively moved in the horizontal direction to obtain the original material. Can be adopted.

In the above description, the inclined spacer 30
Is mounted and fixed on the flat support plate 3. For example, as shown in FIG. 9A, a configuration is adopted in which a groove 31 is provided in the support plate 3 and an inclined spacer 30 ′ is inserted into the groove 31. Can also. In this case, the mounting and fixing of the inclined spacer 30 ′ to the support plate 3 can be easily performed, and when manufacturing a gradient plate having a different inclined shape, as shown in FIG. By appropriately laying a height adjusting member 32 having a desired height under one end or both ends of 30 ′, the inclined spacer 3
0 'can be shared, and there is no need to prepare a different inclined spacer corresponding to each production of a different product,
The switching operation can be simplified.

(Second Embodiment) In the first embodiment,
While the original body was supported in an inclined posture corresponding to the inclination of the top surface of the product, and the original body was cut by being relatively moved in the horizontal direction with respect to the heat ray, in the present embodiment, the original body was moved with respect to the heat ray. Cutting is performed by relatively moving in the horizontal and vertical directions.

That is, the manufacturing apparatus of the present embodiment is significantly different in that, instead of using the inclined spacer 30 in the first embodiment, a moving means that can move in the horizontal and vertical directions is used as the moving means.

The operation of the moving means will be described with reference to FIG. 10 taking as an example a case where a gradient plate similar to that shown in FIG. 4 is manufactured. FIG. 10A shows a cutting state on the end surface on the inclination angle R side (minimum height h3 side), and FIG. 10B shows a cutting state on the end surface on the inclination angle S side (intermediate height h2 side). The state is shown.

As shown in FIG. 10, the moving means of the present example
Until the original body 20 contacts the heating wire 4, the original body 20 is placed so that the height (h1) of the two corners corresponding to both ends of the product longitudinal side from the bottom surface of the original body 20 and the heating wire 4 are the same. The height of the support plate (not shown) is adjusted (see the original body 20 drawn by a solid line in FIG. 10). Then, as the original body 20 is advanced and cut, the original body 20 is gradually raised (see the original body 20 drawn by a broken line in FIG. 10).

That is, when the cutting is completed, the inclination angle R
The end face on the side (the minimum height h3 side) rises in height (h1-h3) from the state at the start of cutting, and the end face on the inclination angle S side (the side at the intermediate height h2) is higher than the state at the start of cutting (h1). The support plate is relatively moved in the horizontal and vertical directions with respect to the heat ray so as to increase the height of -h2).

By controlling the moving means as described above, as shown by the dashed line in FIGS. 10 (a) and 10 (b),
At the end surface on the side of the inclination angle R, cutting is performed to obtain the minimum height h3,
The other end surface on the side of the inclination angle S is cut to obtain the intermediate height h2, so that an inclined surface can be obtained, and a member below the cut surface can be used as a product.

In the above description, the case where the lower side of the cut surface is used as a product is shown, but the upper side of the cut surface may be used as a product. This example will be described with reference to FIG. Note that FIG.
FIG. 11A shows a cutting state on the end surface on the inclination angle R side (the minimum height h3 side), and FIG. 11B shows a cutting state on the end surface on the inclination angle S side (the intermediate height h2 side). I have.

As shown in FIG. 11, the original body 20 (height h)
Until the hot wire 4 abuts on the hot wire 4, the support plate (unsupported) on which the raw material 20 is placed horizontally so that the hot wire 4 is at the same height as the predetermined height (h0-h1) from the bottom surface of the raw material 20. Shown)
Is adjusted (see the original body 20 drawn by a solid line in FIG. 11). Then, as the original body 20 is advanced and cut, the original body 20 is lowered downward by a predetermined amount (see the original body 20 drawn by a broken line in FIG. 11).

That is, when the cutting is completed, the inclination angle R
The end surface on the side (minimum height h3 side) is lower by (h1-h3) than the cutting start state, and the end surface on the inclination angle S side (intermediate height h2 side) is lower than the cutting start state by (h1). The support plate is moved in the horizontal and vertical directions relative to the heat rays so as to lower the height of -h2).

By controlling the moving means as described above, as shown by the dashed line in FIGS. 11 (a) and 11 (b), cutting is performed on a predetermined inclined surface. Can be a product.

Incidentally, such a three-dimensional moving means can adopt a conventionally known configuration, and its control can be automatically performed by a computer.

In this embodiment, no inclined spacer is required to support the original body in an inclined posture corresponding to the inclination of the top surface of the product, and the effect is particularly large when manufacturing a gradient plate having a different inclined shape. In other words, it is not necessary to prepare a different inclined spacer corresponding to each production of a different product, and the operation is greatly simplified because the original is simply placed directly on the support plate.

Also in the case of this embodiment, the length of the original body 20 on the support plate is opposed to the heating wire 4, and the longitudinal side is cut and processed, so that the processing time can be reduced.

Further, similarly to the first embodiment, it is also possible to collectively process the originals which are stacked in multiple stages and arranged in multiple rows, and mass production can be performed efficiently. However, in the case of the present example, it is necessary to arrange the rows in which the original bodies are stacked in a large number of rows with a slight distance therebetween and reset the vertical movement amount by the moving means for each row.

Further, a symmetrical product can be easily processed only by changing the setting of the height control by the moving means, without changing the method of placing the original material as in the first embodiment.

Also, in this embodiment, cutting teeth such as saws and knives can be used as cutting means. In addition, instead of moving the support plate horizontally and vertically during cutting, a heating wire (or the above-mentioned cutting teeth) is horizontally moved. It may be moved and moved vertically.

(Third Embodiment) As described above, in the product setting of the obliquely inclined plate, the setting of the inclination of the top surface cannot be realized by a single plane, and the inclined surface becomes a three-dimensional surface. It is difficult to process. In the present embodiment, an example in which such an inclined surface is simplified with a plurality of planes and manufactured will be described with reference to FIGS.

FIG. 12 shows an example in which the inclined surface of the top surface is simplified by two triangles A and B divided by a diagonal line 70a connecting one corner of the height h1 and a corner of the intermediate height h2. FIG. 3A is a perspective view of a product, and FIG. 3B is a top view illustrating an arrangement state of the original body 20 and the heating wire 4 at the time of cutting.

In the example shown in FIG. 12, the inclined surface simplified by the two triangles A and B is an upwardly convex inclined surface.

In processing such a product, first, FIG.
As shown in (b), the original body 20 is placed on a support plate (not shown) so that the diagonal line 70a is parallel to the heating wire 4. During the cutting of the triangle A, the height of the support plate is adjusted by moving means,
Is slanted so that the surface becomes horizontal and at the same height as the hot wire 4. Similarly, while cutting the triangle B portion, the original body 20 is inclined so that the surface of the triangle B is horizontal and at the same height as the heating wire 4.

FIG. 13 shows an example in which the inclined surface of the top surface is simplified by two triangles C and D divided by a diagonal 70b connecting one corner of the height h1 and the corner of the minimum height h3. FIG. 3A is a perspective view of a product, and FIG. 3B is a top view illustrating an arrangement state of the original body 20 and the heating wire 4 at the time of cutting.

In the example shown in FIG. 13, the inclined surface simplified by the two triangles C and D is a downwardly convex inclined surface.

In processing such a product, first, FIG.
As shown in (b), the original body 20 is placed on a support plate (not shown) so that the diagonal line 70b is parallel to the hot wire 4. Then, while cutting the triangle C, the height of the support plate is adjusted by the moving means, and the triangle C is cut.
Is slanted so that the surface becomes horizontal and at the same height as the hot wire 4. Similarly, while cutting the triangle D, the original body 20 is inclined so that the surface of the triangle D is horizontal and at the same height as the heating wire 4.

As described above, by simplifying the inclined surface of the top surface with several planes, the control of the moving means can be simplified as compared with the second embodiment, and the manufacturing time can be reduced. be able to. Also in this example, a cutting tooth such as a saw or a knife can be used as the cutting means.
