More specifically, the present invention is provided on the upstream side of a cutting device, and the long round material is secured on a reference surface of the cutting device. The present invention relates to a long round material supply device for supplying a round material to a cutting device along a pass line. Background art

As a device for supplying a long round material such as a steel bar or pipe to a downstream cutting device, for example, a long round material supply device 80 as shown in FIG. 14 is conventionally used. The supply device 80 includes a plurality of horizontal rollers 82 arranged along the pass line PL, a workpiece transfer unit 86 that places the long round material 14 on the rollers 82 and supplies the workpiece 14 to the cutting device 84, and It is basically composed of a stock part 90 composed of a plurality of inclined rails 88 inclined upward from the work transfer part 86 at a required angle. Then, one force of the plurality of long round members 14 waiting in parallel with the stock unit 90 is put into the workpiece transfer unit 86 by a placing means (not shown), and the round members 14 are placed on the horizontal roller 82. . Next, the leading end of the long round material 14 is gripped by a feed mechanism (not shown) installed in the cutting device 84, and the long round material 14 is intermittently supplied along the pass line PL.

[0003] In the cutting device 84 positioned downstream of the supply device 80, a work table 92 is disposed below the cutting tool 96, and the long round material 14 supplied from the supply device 80 is set on the upper surface of the work table 92. To the specified reference plane T. At this time, as shown in FIG. 14, the long round material 14 is held at the same height as the reference surface T by the horizontal roller 82 of the supply device 80, so that the long round material 14 is adjusted in height. It is sent directly to work table 92 without performing it. That is, the horizontal roller 82 of the supply device 80 is set so that the upper surface 82a of the roller coincides with the reference surface T of the cutting device 84. The height of surface T is secured. When the long round material 14 reaches the fork table 92, the vise 94 provided on the table 92 clamps and fixes both side portions of the long round material 14. Then, a cutting tool 96 such as a circular saw is mounted on the long circular material 14.

Disclosure of the invention

Problems to be solved by the invention

[0004] By the way, as described above, the conventional cutting device 84 has a mainstream in which the reference surface T is set below the long circular material 14 (hereinafter referred to as the lower reference surface). The supply device 80 for supplying the long circular material 14 to the lower reference surface T is also designed to correspond to the lower reference plane T. However, the cutting device 84 having the lower reference surface T has, for example, a cutting surface in which the cutting tool 96 easily entrains chips when cutting when the long round material 14 is a pipe material. There was a problem that quality deteriorated. Therefore, as a cutting device for coping with this problem, a cutting device 56 in which the reference plane T is set above the long round member 14 as shown in FIG.

That is, the cutting device 56 includes a beam 58 having a required rigidity, and a reference surface (hereinafter referred to as an upper reference surface) T is set on the lower surface of the beam 58. The long round member 14 is pressed against the upper reference plane T and fixed with the vise 94, and the cutting tool 96 is raised to cut the long round member 14. This makes it difficult for the cutting tool 96 to entrain chips generated during cutting, and improves the cutting surface quality of the long round material 14. However, the conventional supply device 80 is compatible only with the cutting device 84 having the lower reference surface T, and the supply device corresponding to the cutting device 56 having the upper reference surface T is currently proposed. It is the actual situation.

The lower horizontal rollers 28 and 28 are moved from the first position shown in FIG. 1 to the second position shown in FIG. 7 (b), so that the long round material 14 placed on the rollers 28 and 28 is moved. Is lifted up to pass line PL.

The lower horizontal rollers 28, 28 are disposed on a lifting platform 34 positioned below the upper horizontal rollers 26, 26. As shown in FIGS. 1 and 5 (a), the lift 34 is supported by a hydraulic cylinder 22 disposed on a lower frame 20 extending in the horizontal direction, and the cylinder 22 is operated. It is designed to be moved up and down. That is, the lower horizontal rollers 28 and 28 are moved from the first position to the second position by moving up and down together with the lifting platform 34 by the hydraulic cylinder 22.

As shown in FIG. 5 (a), a pair of slide rails 40, 40 extending in the vertical direction are provided at both ends in the longitudinal direction of the lifting platform 34. As shown in FIG. 5 (b), the slide rails 40, 40 are formed to have a substantially H-shaped cross section, and are provided at a required position of the vertical frame 20, and the guide members 42 with built-in linear bearings. It is slidably engaged with the groove 42a. That is, as shown in FIGS. 7 (a) and 7 (b), the slide rails 40 and 40 and the guide member 42 are engaged so that the lifting platform 34 can be lifted and lowered while maintaining a horizontal posture.

The horizontal roller 28 is configured to tilt at the required angle prior to rising to the second position. That is, the lower horizontal rollers 28 and 28 are tilted by the pneumatic cylinders 38 and 38 provided inside the lifting platform 34 as shown in FIG. 5 (a) and FIG. The pneumatic cylinders 38 and 38 operate before the lower horizontal rollers 28 and 28 are raised, push up the end portions 28a and 28a on the stock 18 side of the lower horizontal rollers 28 and 28, and lower the lower horizontal rollers 28. To tilt It is configured. The force by which the pneumatic cylinder 38 pushes the lower horizontal roller 28 is set smaller than that of the hydraulic cylinder 22, and when the lower horizontal roller 28 reaches the second position, as shown in FIG. 6 (b). The lower horizontal roller 28 is piled on the force of the pneumatic cylinder 38 and returned to the horizontal posture by the force of the hydraulic cylinder 22. Note that the structure for tilting the lower horizontal roller 28 is not limited to the pneumatic cylinder 38 shown here, and a conventionally known mechanism can be appropriately employed.

[0028] The plurality of vertical rollers 30,30 are provided vertically at a required interval on the side of the pass line PL (on the side opposite to the stock portion 18), and are formed of the long round material 14 put into the lower horizontal roller 28. It is configured to restrict the position in the lateral direction. As shown in FIG. 3, each vertical roller 30 is provided on the lower end side of an arbitrary inclined rail 44 constituting the stock portion 18 so that its rotating shaft 30a is vertical. In the first embodiment, the vertical rollers 30 and 30 are provided below the two inclined rails 44 and 44 located on the inner side, and are separated from each other by a predetermined interval.

That is, the supply device 10 according to the first embodiment sandwiches the long round material 14 between the upper horizontal rollers 26, 26 and the lower horizontal rollers 28, 28, thereby making the round material 14 the height of the upper reference plane T. In addition, the vertical rollers 30 and 30 regulate the lateral direction. Then, after the position of the long round material 14 is regulated by these three rollers 26, 28, and 30, the long round material 14 is stably fed to the downstream cutting device 56 along the pass line PL. It is configured to be

[0030] (About Stock Department)

As shown in FIGS. 1 to 3, the stock unit 18 is provided on the side of the pass line PL, and includes a plurality of inclined rails 44 that are inclined upward as the distance from the pass line PL increases. When a plurality of long round members 14 are introduced into the inclined rail 44, the round members 14 roll on the inclined rail 44 and are stocked in a parallel state. In addition, as shown in FIG. 2, a regulating plate 46 is provided on the outer side of the inclined rail 44 provided on the most downstream side so that the ends of the long round members 14 are aligned.

[0031] As shown in FIG. 1 and FIG. Slope members 36, 36 which are located above the first position of the lower horizontal rollers 28, 28 and are inclined downward toward the vertical rollers 30, 30 are provided so as to be close to the vertical rollers 30, 30. . Each slope member 36 is formed in a substantially right triangle shape on the side surface, and the inclined lower end force of the inclined rail 44 protrudes upward at a required height, and the long round material 14 placed on the inclined rail 44 is a slope. The rolling is restricted by coming into contact with the protruding end of the member 36.

In addition, as shown in FIG. 1, an inclined surface 36 a that inclines downward as it moves away from the inclined rail 44 is formed on the upper surface of the slope member 36. The long round material 14 put on the inclined surface 36a rolls on the inclined surface 36a and comes into contact with the vertical roller 30, thereby temporarily stopping in a state where the lateral position is regulated. Is done. In other words, the slope member 36 restricts the rolling of the long round material 14 on the inclined rail 44 and ensures that the long round material 14 placed on the slope member 36 abuts against the vertical roller 30. It plays a role. As shown in FIG. 6 (a), the protruding height of the slope member 36 is set to be higher than the lower horizontal rollers 28 and 28 in the most tilted state at the first position.

[0033] As shown in FIG. 3, on the side of the slope members 36, 36, one of the long round materials 14 waiting in the stock portion 18 is lifted and placed on the slope members 36, 36. 48,48 are installed. Each mounting means 48 is a plate-like member having a shape as shown in FIGS. 8 (a) and 8 (b), and an end portion spaced from the stock portion 18 is supported by the upper frame 20 in the support portion 12. It is supported via a shaft 50. Further, the lower portions of the mounting means 48, 48 are connected via a rotary shaft 52 and a lifting / lowering portion 24a of a swing cylinder 24 supported swingably on the lower frame 20, and FIG. As shown in b), when the oscillating cylinder 24 is operated, both mounting means 48 and 48 are oscillated around the respective supporting shafts 50 in conjunction with each other.

[0034] In addition, each mounting means 48 is always positioned below the rail 44 so that the upper portion 48a does not interfere with the elongated round member 14 on the inclined rail 44 (in conjunction with FIG. As shown in Fig. 8 (b), the leading long round material 14 in contact with the slope member 36 is lifted up by the swing cylinder 24. Then, it is lifted up by the upper part 48a of the mounting means 48. The obtained long round material 14 rolls on the upper part 48a and is temporarily moved onto the inclined surface 36a of the slope member 36. In addition, as shown in FIGS. Two placing means 48, 48 are provided, which are mutually connected by the rotating shaft 52 and the connecting shaft 54. Are connected. However, the configurations of the mounting means 48 and the peristaltic cylinder 24 described above may be other configurations than those limited to the first embodiment. Three or more mounting means 48 may be installed in the supply device 10.

[0035] (Operation of Example 1)

Next, the operation of the supply device 10 according to the first embodiment will be described. First, a plurality of long round materials 14, 14 are put on the inclined rails 44,44. Since each inclined rail 44 is inclined downward at a required angle toward the workpiece transfer section 16, the long round material 14 that has been initially charged rolls until it contacts the slope member 36. Further, the remaining long round members 14 are brought into contact with each other and waited in the stock unit 18 in a parallel state. Note that the long round members 14 are aligned by their tips abutting against a restriction plate 46 provided on the downstream side of the stock portion 18.

Next, the placing means 48 is operated, and the leading long round member 14 in contact with the slope member 36 is temporarily placed on the slope member 36. That is, as shown in FIGS. 8 (a) and (b), the peristaltic cylinder 24 is actuated to raise the elevating part 24a. Accordingly, both mounting means 48, 48 connected to the lifting / lowering part 24a via the rotating shaft 52 swing synchronously upward with the supporting shafts 50, 50 as fulcrums, respectively. Then, it is lifted to the upper part 48a of the leading long round material 14 force placing means 48 that is in contact with the slope member 36 (FIG. 8 (b)). The elongated round member 14 lifted by the placing means 48, 48 rolls on the upper portions 48a, 48a of the placing means 48, 48 and is transferred to the slop members 36, 36. Furthermore, since the inclined surfaces 36 &, 36 & of the slope members 36,36 are inclined downward toward the vertical rollers 30,30, the long round material 14 contacts the vertical rollers 30,30 (state of FIG. 1). . At this time, the lower horizontal rollers 28 and 28 in the first position are positioned below the slope members 36 and 36 and do not interfere with the long round member 14.

[0037] When the elongated round member 14 is placed on the slope members 36, 36, each pneumatic cylinder 38 is operated to lift the end portion 28a of the lower horizontal roller 28 as shown in FIG. 6 (a). The lower horizontal roller 28 is tilted about the support shaft P. Even if the lower horizontal rollers 28, 28 are tilted, they are positioned below the slope members 36, 36, so that they do not interfere with the long round material 14 on the inclined surfaces 36a, 36a. Next, as shown in FIG. 7 (a), the hydraulic cylinder 22 operates to raise the lifting platform 34, and the long round material 14 is placed on the lower horizontal rollers 28, 28.

[0038] That is, the long round member 14 is moved onto the slope members 36, 36, and further, the lower horizontal roller 2 After the tilts 8 and 28 (required timing), the hydraulic cylinder 22 is operated to raise the lower horizontal rollers 28 and 28. At this time, as shown in FIG. 7 (a), the long circular material 14 placed on the lower horizontal rollers 28, 28 is inclined downward toward the vertical rollers 30, 30 on the lower horizontal rollers 28, 28. As a result, the roller moves up while being in contact with the vertical rollers 30 and 30, and the lateral position regulation is not released. Further, while the long round material 14 is rising, it does not roll on the lower horizontal rollers 28, 28 and fall from the lower horizontal rollers 28, 28. Since the elevator 34 is guided by the two slide rails 40, 40 engaged with the guide member 42, the elevator 34 is raised in a horizontal posture. Accordingly, the lower horizontal rollers 28 and 28 are raised at the same level, and the long round member 14 is stably lifted.

[0039] As shown in FIG. 7 (b), when the lower horizontal rollers 28, 28 reach the second position, the long round material 14 on the rollers 28, 28 is moved to the lower surface 26a of the upper horizontal rollers 26, 26, Pressed against 26a. At this time, since the force of the hydraulic cylinder 22 is set to be larger than the force of the pneumatic cylinders 38 and 38, the lower horizontal rollers 28 and 28 are tilted in the opposite direction while piled on the force of the pneumatic cylinders 38 and 38, It is returned to the horizontal position again (Fig. 6 (b)). That is, the long round member 14 is sandwiched between the upper horizontal rollers 26 and 26 and the lower horizontal rollers 28 and 28 by the urging force of the hydraulic cylinder 22 and is supported at the same height as the upper reference plane T of the cutting device 56.
