Description of the Invention: [Technical Field] The present invention relates to a method of supplying a certain height of a bottom surface of a round bar material and an apparatus therefor. [Prior Art] Conventionally, in a cutting machine such as a circular sawing machine or a horizontal band sawing machine, a material supply device ' is provided on one side (upstream side, mechanical rear side) of the cutting machine and on the other side of the cutting machine (downstream side, machine front side): A product platform for the product cut by the cutting machine is provided. In the material supply device, when a plurality of long strips of material such as a round bar are sequentially cut, the long material and the remaining material used after cutting are stored on the rear side of the cutter. The supply conveyor is supplied to a material conveyor to be described later, and a material conveyor composed of a plurality of V-groove rollers. In a known supply device (for example, Patent Document 1), the material conveyor is configured to be capable of freely rotating a V-groove roller in a material conveying direction (X-axis direction), and conveying the material to a cutter, the supply conveyor The machine is configured to supply the material to the material conveyor by rotating the chain in a direction orthogonal to the material conveying direction (the γ-axis direction) (the γ-axis direction), and the material conveyor has: for receiving the supply from the supply conveyor The material of the material position, and the material used to place the material on the v-roller lifting device, whereby the V-groove roller can be freely raised and lowered to place the material in the vertical direction (Z-axis direction) perpendicular to the X-axis. 'Set to be free to determine its moving position. [Prior Art Document] -5-201200320 [Patent Document] [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei 7-24524-A SUMMARY OF INVENTION [Problems to be Solved by the Invention] With reference to Fig. 1, the above Patent Document 1 is described. The material supply device will be described in the case of conveying the material to the cutter. First, the right side surface (the right side of the first drawing) of the material W such as the round bar placed on the chain of the supply conveyor (not shown) is positioned on the main vise reference line of the cutting machine by the supply conveyor. The KK line has a consistent position. Next, the center of the V groove of the V-groove roller 101 of the material conveyor composed of the plurality of V-groove rollers 101 is horizontally moved in the Y-axis direction to a position coincident with the center of the material W, and then the drawing is omitted. The material conveyor shown in the figure is raised to a predetermined position by an elevator cylinder (not shown), and the V-groove roller 101 is moved up and down in the z-axis direction to support the material W on the V-groove roller. The roller 1 0 1 is rotationally driven in the material conveying direction in the X-axis direction, and the length required to convey the material W is fixed by fixing the fixed vise of the cutter. When the material supply device described in Patent Document 1 is used to cut a long material such as a round bar, the following problems may occur. Referring again to FIG. 1 'Locating the right side surface of the material W having different diameters on the main vise reference line K - K line 'When the material w is raised and supported to a certain position by the V groove roller 1 ο 1 'material and V groove The position where the roller tangent abuts will be different 201200320 because of the material diameter. Therefore, the distance from the bottom surface of the V-groove roller to the bottom of the material changes, so the height of the bottom surface of the material is different from the mechanical feeding line. For example, when the angle of the v groove of the v groove roller 101 is 151 degrees, the difference between the height of the bottom surface of the round bar supported by the V groove roller 101 and the diameter of the round bar of φ 330 and φ 30 is about 4.9 mm. In this way, when the round bar material W is conveyed to a cutting such as a band saw, the lifting height of the V groove roller is adjusted so that the height of the round bar surface of φ 30 becomes the carrying height of the conveying roller on the cutting machine side. When the bottom surface of the round bar is located at four places higher than the conveyance height on the cutting machine side, the material W is dropped in the conveyed material, and the bottom surface height of the round bar adjusted to φ 330 is reversed. When the cutting machine side is transported, the bottom surface of the round bar of Φ 30 is located below 4.9 mm, so the roller is moved to the cutting machine side, which may cause difficulty in material transportation.

Parts are omitted with the same drawing number. In the above configuration, the amount of movement up to the roller reference line RL is calculated based on the material diameter information previously stored in the control device and the current position information of the drive motor, and the drive motor 51 is driven forward or reversed to drive the front The lifting guide 31 f rotates with the bevel gear 50 that engages with the bevel gear 49 of the synchronous rotating shaft 47 on the rear lifting guide 31i, and rotates the driving shaft 43 that is axially supported by the supporting base portion 34, and the front lifting guide The piece 31f and the rear lifting guide 3ir are simultaneously freely movable to and from the lifting base 15, and the roller reference line at the center of the V groove of the roller 3 can be conveyed by the material provided on the column 17 of the lifting base 15. The position of the RL is moved and positioned with respect to the main vise reference line B1, and in this way, the round bar side height adjusting device 10 having the round bar side height adjusting means is provided. That is, the material feeding device 7 sets the roller reference line RL· at the center of the material after the material supply end surface 7 is positioned at the same time as the material end face BL is positioned at the main body vise reference line BL, in this manner Since the center of the V groove of the material conveying roller 3 is moved and positioned in the Y-axis direction, when the cylinder 59 is actuated after the positioning, the material is supported by the material conveying roller 3 so that the material is gripped by the main vise. When the main vise reference line BL is moved and positioned, the front elevation guide 3 1 f and the rear elevation guide 3 1 r ' move in the γ-axis direction along the inclined surface 37 and simultaneously move up and down in the Z-axis direction. Therefore, the material conveying roller 3 also moves up and down in proportion to the amount of movement in the γ-axis direction. -15- 201200320 The amount by which the material conveying roller 3 moves up and down in proportion to the amount of movement in the Y-axis direction will be described with reference to Fig. 8. As shown in Fig. 8, for example, round bar materials W1 to W4 of various diameters are placed on the V grooves of the material conveying roller 3 so that the material conveying roller 3 is horizontally oriented in the direction of the main vise reference line BL in the z-axis direction. Moving, positioning the right end faces of the round bar materials W 1 to W4 of various diameters to be in contact with the main vise reference line BL, and pulling out: passing the bottom surface of the round bar materials W 1 W W 4 and the material conveying roller The intersection of the center V of the V groove of the sub 3 is Α1 to Ρ4 points of the straight line Α-Α. The straight line A-Α is a downward slope inclined to the lower right side, and the slope thereof is such that when the radius of the round bar material W 1 is R, the radius of the round bar material W4 is r, and the difference between the heights of the intersection points P1 and P4 is When ΔΖ, it is represented by ΔΖ/(ΙΙ·Γ) = ί3ηθ. Θ is the angle formed by the straight line Α_Α and the horizontal line parallel to the Υ axis. Therefore, if the slope is zero, the heights of the bottoms of the respective round bar materials W1 to W4 can be made the same. That is, if the inclination of the above-described guide base 35 becomes the inclination of AZ/(Rr) which is raised toward the side of the main vise reference line BL, when the right end faces of the round bar materials W1 to W4 are positioned to be The height difference generated by the main vise reference line BL can be zero, and the round bar bottom height adjusting device 12 having the round bar bottom height adjusting means can be used. In the embodiment in which the height of the bottom surface of the round bar material of the present invention is constant, the angle of the V groove of the material conveying roller 3 is set to 15 Γ, and the diameter of the round bar material W to be transported is φ 3 3 0 to φ 3 0. Therefore, the slope Θ of the inclined surface 3 7 is set to about 1 / 3 0 (the angle is about 1.9 degrees) according to the above theory -16-201200320, the angle and inclination of the v groove of the material conveying roller 3 for the above material. The relationship of the slope θ of the surface 37 will be described with reference to Fig. 9. Referring to Fig. 9, the angle of the V groove 61 of the material conveying roller 3 is 2α' separated by the left and right sides of the center line V. The center of the large rod material %1 is 〇i 'the radius is R' small diameter circle The center of the rod material W2 is 〇2, and the radius is Γ 'the state in which the round bar materials W1 and %2 are tangentially engaged in the groove 61 of the material conveying roller 3'. The bottom point P3 of the V groove 6 1 The distance between the bottom point P1 of the round bar material w1 is Z' and the distance between the bottom point P3 and the bottom portion P2 of the round bar material W2 is Z'. The slope θ of the inclined surface 37 is "z axis". The ratio of the amount of adjustment of the direction / the difference of the radius of the round bar material is expressed by the following formula (1). [Math 1] tanΘ- (Z_Z ) / (R~r) = (1-sino?) /sina · · (1) where sina=r’/a, =r/a, 0. <α<9 0. . Next, the drawing of the material conveying roller 3 with respect to the center line V of the V groove 61 at an angle β is shown in the figure. Referring to Fig. 10, the distance between the bottom point Ρ3 of the V groove 61 and the bottom point Ρ1 of the round bar material W1 in the x-axis direction (vertical direction) is Ζ, and the bottom point Ρ3 of the V groove 61 and the center of the round bar material W2 The distance from the x-axis direction (vertical direction) to 02 is b '. Similarly, the distance between the bottom point Ρ 3 and the bottom Ρ 2 of the round bar material W2 in the Z-axis direction (vertical direction) is Z'. (= b'-r), when the distance between the center 〇1 of the round bar material W1 and the above-described bottom point P 3 is Η, the slope Θ of the inclined surface 37 is expressed by the following formula (2). When β = 0, it is consistent with the above formula (1). -17- 201200320 [Math 2] tan0= (1-1') / (Rr) = (cos/S-sinor) /sina · (2) where sinor=r'/a'=r/a, H= a*cos/S, 0. < a < 9 〇. . As shown in Fig. 1, the inclination Θ2 ' in the Y-axis direction of the center V' of the V-groove 61 caused by the center inclination angle β of the v-groove 6 1 with respect to the center line V of the v-groove 61 is "Υ axis" The ratio of the amount of adjustment of the direction / the difference of the radius of the round bar material, the distance between the bottom point Ρ3 of the V groove 61 and the central axis V of the round bar material W1 in the z-axis direction is C, and the round bar material W2 When the distance between the centers of the x-axis directions is C ', it is expressed by the following formula (3). [Math 3] tan0 2 = (C-C') / (Rr) = siri / 8 / sina · · (3) Figure 11 is for the outer diameter of the round bar material W without tangential contact with the material transport The slope of the inner surface of the V groove of the roller 3 is shown in the drawing. The figure shows the V groove of the material conveying roller 3 having the half angle α at the angle of the V groove of the material conveying roller 3. The sheet portion P4 is engaged with the outer diameter of the large-diameter round bar material W 1 and the small-diameter material W 2 . In Fig. 11, the half angle α of the V groove, the radius r of the small diameter material W2, the distance L between the bottom P3 of the V groove and the sheet portion P4 of the V groove are known, and the bottom surface of the small diameter material W2 and the center of the V groove. The intersection of the line V is P2, the intersection of the V-center line V of the large-diameter material W1 is P 1, the center of the large-diameter material W 1 is 〇1, the center of the small-diameter material W2 is 02, the angle Ρ101Ρ4 = Δ1, the angle Ρ202Ρ4 = Δ2, IJ r / sina = L / sinA2, so sinA2 = Lxsina / r, so △ 2 = siη -1 (LXsina / r), △ 1 = siη -1 (Lχsiηa / R). -18- 201200320 Thus, θ = 18(Γ-(α + Δ2), so the distance D between the bottom P3 of the V groove and the center 〇2 of the small-diameter material W2 is: [Math 4] D=sin (180.-(〇i+sin-UL*sin〇f/r)))*r/sina . (4) Therefore, the distance X between the bottom P3 of the V groove and the P2 of the bottom side of the small-diameter material W2 It is expressed by the following formula (5). [Math 5] X=sin(180° -(a+sin-1(L*sinor/r)))*r/sin〇fr· . . (5) Similarly, from Ο 1 of W 1 to距离1 The distance between the bottom P3 of the V groove, when the (XX,) is considered, the ratio of (XX,)·(R_r) is changed by the radius r, and the angle Δ changes, so it is a variable ratio relationship. That is to say, it is not possible to adopt a simple mechanism of the embodiment of the present invention which is simply represented by a line. However, since the length L and the angle α due to the angle Δ are constant, r is used as a fractional function of the variable, when the center 〇 and Ρ4 of the material W are? 3 When the angle of the structure is 90° or more, the material W is abutted by the end point of L, so L xsina<r 〇 Therefore, a certain degree of straight line approximation is possible, so if the slope is made in multiple stages, it is possible to obtain Practical range. If the positioning control is performed correctly, it is also possible to adopt a mechanism that has a position calculation result and uses an arbitrary positioning such as servo control. According to the relationship between the width of the V-groove and the diameter of the material of the round bar, the ratio of the increase in the diameter of the round bar to the bottom of the round bar is gradually reduced, so it is not a practical range to use the slope in the first segment. When the guide post 3 3 is moved in the direction of the main -19-201200320 body vise reference line BL by the material supply device as described above, the lifting pedestal 15 is lifted to the side of the cutting machine side. When the height (the feed lines of FIGS. 2, 3, and 4) coincides with the position of the material feed line PL, the height of the bottom surface of the round bar material is set to the rising slope of the guide base 35, respectively. The difference between the height of the bottom surface of the material supported by the V-groove roller of the material conveyor and the conveyance height on the cutter side is mechanically corrected, and the material can be conveyed to a cutter having the same height. Therefore, when the round bar material is conveyed to the cutter, the operator does not need to pay attention to the difference between the height of the bottom surface of the material supported by the V-groove roller of the material conveyor and the conveyance height on the cutter side. There is a case where the material collides with the conveying roller on the cutting machine side and material transportation is difficult. The material feed line PL is located slightly above the chain 11 of the material supply conveyor 7. In the above-described embodiment of the present invention, the front elevation guide 31f and the rear elevation guide 31r are moved along the inclined surface 37 of the slope Y in the Y-axis direction, and are supported by the V groove of the material conveying roller 3. The height of the bottom surface of the material W is different due to the difference in diameter, and is mechanically corrected by the inclination of the guiding base, and the front lifting guide 3 1 f and the rear lifting guide 3 11 are set to be The Y-axis direction and the Z-axis direction are moved, and the Y-axis movement amount and the Z-axis movement amount are individually controlled by the control device by synchronous control or asynchronous control. That is, the Y-axis movement amount and the Z-axis movement amount of the material conveying roller 3 are synchronously controlled or asynchronously controlled by the control device, thereby correcting the support by the V groove of the material conveying roller 3. The height of the bottom surface of the material W may also vary depending on the difference in diameter. For the method of tangentially supporting the round bar material by the V-groove surface, for example, -20-201200320, according to the Japanese Building Standard Law, it is desirable to have a horizontal force (0.2 during moderate earthquake) with respect to its own weight as a safe structure. In the case where the earthquake is less or the above reference is considered, it is preferable to apply a horizontal external force of 5% to 25% of the weight of the round bar to the round bar material. On the other hand, the angle "which can be withstood by the V-groove surface" is the above-mentioned angle α and the above-mentioned angle (3, in the case of "9〇-angle α + angle β" or "90.·angle α-angle β" Among the inclinations of the two sides, the angle a for the other side is about the weight of the above-mentioned round bar material and the horizontal external force applied to the center of the round bar material, which can be 5% to 25% of the weight of the bar itself. The angle at which the horizontal external force is equalized is taken as the angle a. The point ' is described in the first and second figures. The first two is a display of the moment balance around the point A, and the weight of the workpiece W is It is explained by the angle a of the balance of the horizontal external force F. The weight w is decomposed into the horizontal direction of the Η and the vertical direction of the V, wherein the horizontal direction component Η is balanced with the horizontal external force F. At this time, by regulations or any specifications, etc. If the horizontal force F is allowed to allow, for example, 20% of its own weight W, the angle a is determined by ta η - 1 ( Η / V ) and 1 1 · 3 degrees. ο When the workpiece weight W is 150 kgf, the horizontal external force is W. 1%~30%, calculate the angle a, transfer the angle β from 0° to T's a'(= 90°-a), borrow The (H/V) angle which is changed by the angle β is calculated by the width (one side) of the V groove when φ 400 is placed at V, as shown in Fig. 13. At this time, according to the design intention of the machine, one side The V-groove width is 40 mm or more and 9 5 mm or less, and the horizontal external force F is calculated to be 5% or more and 25% or less of the workpiece weight W, and the area conforming to the condition is surrounded by a thick frame. According to its knot - 21 - 201200320 It is permissible to determine the angle β in the range from 0° to 5. In the case of the above-described angle β, the horizontal external force applied to the round bar material from the safety surface as described above is averaged on both sides in the x-axis direction, and Although it is a theoretically better shock-resistant angle with respect to the x-axis direction, and the horizontal force is considered together with the allowable range of its own weight, the angle β can only obtain a substantial effect from 0° to 5°. The present invention is not limited to the description of the embodiments of the present invention, and can be implemented in various other forms by appropriately changing the contents of the present invention.
