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
[0002] 鉄棒やパイプ等の長尺丸材を下流の切削装置へ供給する装置として、例えば、図 14に示すような長尺丸材供給装置 80が従来力 使用されている。この供給装置 80 は、パスライン PLに沿って水平ローラ 82が複数基配設され、該ローラ 82上に長尺丸 材 14を載置して切削装置 84へ供給するワーク移送部 86と、該ワーク移送部 86から 所要角度で上方傾斜する複数の傾斜レール 88からなるストック部 90とから基本的に 構成されている。そして、ストック部 90に並列状態で待機する複数の長尺丸材 14の 1 つ力 図示しない載置手段によってワーク移送部 86へ投入され、該丸材 14は水平口 ーラ 82上に載置される。次いで、長尺丸材 14の先端部を切削装置 84に装備された 図示しない送り機構が把持し、長尺丸材 14はパスライン PLに沿って間欠的に供給さ れる。 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] 供給装置 80の下流に位置する切削装置 84は、切削工具 96の下方にワークテー ブル 92が配設され、供給装置 80から供給された長尺丸材 14は、ワークテーブル 92 の上面に設定された基準面 Tまで送られる。この時、図 14に示すように、長尺丸材 1 4は、供給装置 80の水平ローラ 82によって前記基準面 Tと同じ高さに保持されてい るので、長尺丸材 14はその高さ調整を行なうことなぐ直接ワークテーブル 92上へ送 り込まれる。すなわち、供給装置 80の水平ローラ 82は、そのローラ上面 82aが切削 装置 84の基準面 Tと一致するよう設定されており、長尺丸材 14は、ワーク移送部 86 へ投入された段階で、基準面 Tの高さが確保されている。なお、長尺丸材 14がヮー クテーブル 92まで到達すると、該テーブル 92上に設けられたバイス 94が長尺丸材 1 4の両側部を挟持して固定する。そして、丸鋸等の切削工具 96が長尺丸材 14の上
方側から下降して、該丸材 14は所定の長さに切断される (例えば、特許文献 1参照)。 特許文献 1 :特開平 10— 6169号公報 [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. The round member 14 is cut down to a predetermined length by descending from the side (see, for example, Patent Document 1). Patent Document 1: Japanese Patent Laid-Open No. 10-6169

発明が解決しょうとする課題 Problems to be solved by the invention
[0004] ところで、従来の切削装置 84は、上記したように基準面 Tが長尺丸材 14の下方 (以 下、下方基準面と呼ぶ)に設定されたものが主流であり、この切削装置 84に長尺丸材 14を供給する供給装置 80も、この下方基準面 Tに対応するよう設計されている。しか しながら、下方基準面 Tを備えた切削装置 84は、例えば、長尺丸材 14がパイプ材で ある場合には、切断する際に切削工具 96が切粉を巻き込んでしまい易ぐ切削面の 品質が低下する問題があった。そこで、この問題に対処する切削装置として、図 15に 示すように、基準面 Tが長尺丸材 14の上方に設定された切削装置 56が考えられる。 [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.
[0005] すなわち、この切削装置 56は、所要の剛性を有するビーム 58を備え、該ビーム 58 の下面に基準面 (以下、上方基準面と呼ぶ) Tが設定される。そして、この上方基準面 Tに長尺丸材 14を押し当てると共に、バイス 94によって固定したもとで、切削工具 96 が上昇して長尺丸材 14を切削するようになっている。これにより、切削時に生ずる切 屑を切削工具 96が巻き込み難くなり、長尺丸材 14の切削面質が向上する。ところが 、従来の供給装置 80は、下方基準面 Tを備えた切削装置 84にのみ対応したもので あり、このような上方基準面 Tを備えた切削装置 56に対応した供給装置は、現在提 案されて 、な 、のが実情である。 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.
[0006] そこで本発明は、上方に基準面を備えた切削装置に対応した長尺丸材供給装置 を提供することを目的とする。 [0006] Accordingly, an object of the present invention is to provide a long round material supply device corresponding to a cutting device having an upper reference surface.

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] スロープ部材 36,36上に長尺丸材 14が載置されると、各空気圧シリンダ 38が作動 して、図 6(a)に示すように、下方水平ローラ 28の端部 28aを持ち上げ、該下方水平口 ーラ 28は支軸 Pを中心に傾動される。なお、下方水平ローラ 28,28は傾動した状態 であってもスロープ部材 36,36より下方に位置しているので、傾斜面 36a,36a上の長 尺丸材 14と干渉することはない。次いで、図 7(a)に示すように、油圧シリンダ 22が作 動して昇降台 34を上昇させ、下方水平ローラ 28,28上に長尺丸材 14が載置される。 [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] すなわち、長尺丸材 14がスロープ部材 36,36上に移され、更に、下方水平ローラ 2
8, 28が傾動した後に (所要のタイミング)、油圧シリンダ 22が作動して下方水平ローラ 28, 28を上昇させるようになつている。この時、図 7(a)に示すように、下方水平ローラ 2 8,28へ載置された長尺丸材 14は、下方水平ローラ 28,28が垂直ローラ 30,30側へ 下方傾斜しているので、垂直ローラ 30,30に当接したまま上昇し、横方向の位置規 制が解除されることはない。また、長尺丸材 14が上昇中、下方水平ローラ 28,28上を 転がって、該下方水平ローラ 28,28から転落することもない。なお、昇降台 34は、ガ イド部材 42に係合した 2つのスライドレール 40,40によって案内されているので、昇 降台 34は水平姿勢のまま上昇される。従って、両下方水平ローラ 28,28は同レベル で上昇して、長尺丸材 14は安定的に持ち上げられる。 [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] 図 7(b)に示すように、下方水平ローラ 28,28が第 2位置に到達すると、該ローラ 28, 28上の長尺丸材 14が上方水平ローラ 26, 26のローラ下面 26a,26aに押し当てられ る。この時、油圧シリンダ 22の力は空気圧シリンダ 38,38の力よりも大きく設定されて いるので、下方水平ローラ 28,28は該空気圧シリンダ 38,38の力に杭して反対方向 へ傾動され、再び水平姿勢に戻される (図 6(b))。すなわち、油圧シリンダ 22の付勢力 によって長尺丸材 14は上方水平ローラ 26,26と下方水平ローラ 28,28とで挟持され て、切削装置 56の上方基準面 Tと同じ高さに支持される。更に、長尺丸材 14は、こ の時点においても垂直ローラ 30,30に当接したままなので、横方向の位置規制もなさ れている。 [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. Further, since the long round member 14 remains in contact with the vertical rollers 30 and 30 even at this time, the lateral position is also restricted.
[0040] すなわち、実施例 1に係る供給装置 10によれば、下方水平ローラ 28,28上の長尺 丸材 14は、ローラ下面 26a,26aを上方基準面 Tに一致させた上方水平ローラ 26,26 に押し当てられて上方基準面 Tが確保される。従って、上方基準面 Tを有する切削装 置 56に長尺丸材 14を供給することが可能となる。 [0040] That is, according to the supply device 10 according to the first embodiment, the long round material 14 on the lower horizontal rollers 28, 28 includes the upper horizontal rollers 26, 26a, 26a having the roller lower surfaces 26a, 26a aligned with the upper reference plane T. The upper reference plane T is secured by being pressed against 26. Accordingly, the long round material 14 can be supplied to the cutting device 56 having the upper reference plane T.
[0041] 次いで、長尺丸材 14は、その先端を切削装置 56の送りバイス (図示せず)等によつ て挟持され、切削装置 56へ間欠的または連続的に送られる。この時、長尺丸材 14 は上方水平ローラ 26, 26、下方水平ローラ 28,28および垂直ローラ 30,30によって挟 持された状態なので、長尺丸材 14はパスライン PLからずれることなく確実に切削装 置 56へ送られる。長尺丸材 14が切削装置 56に完全に送られると、油圧シリンダ 22 が昇降台 34を下降させて、下方水平ローラ 28,28は、図 1の如ぐ第 1位置まで戻さ
れる。 Next, the end of the long round material 14 is pinched by a feed vise (not shown) or the like of the cutting device 56 and is sent intermittently or continuously to the cutting device 56. At this time, since the long round material 14 is sandwiched between the upper horizontal rollers 26 and 26, the lower horizontal rollers 28 and 28, and the vertical rollers 30 and 30, the long round material 14 is reliably cut without being displaced from the pass line PL. Sent to device 56. When the long round material 14 is completely sent to the cutting device 56, the hydraulic cylinder 22 lowers the lifting platform 34, and the lower horizontal rollers 28, 28 are returned to the first position as shown in FIG. It is.

[0044] また、下方水平ローラ 62,62は、前記昇降台 34において、各中間部分 62bがパス ライン PLの鉛直下方に位置するよう設けられている。すなわち、実施例 2に係る下方 水平ローラ 62,62は、長尺丸材 14を持ち上げ、上方水平ローラ 26,26に押し当てて 上方基準面 Tを確保すると共に、長尺丸材 14を前記中間部分 62b,62bで保持する ことで、長尺丸材 14の横方向の位置規制をなしている。従って、実施例 2の供給装 置 60には、実施例 1において長尺丸材 14に対して横方向の規制を行なう垂直ロー ラ 30,30が設けられていない。また、実施例 1の供給装置 10では、下方水平ローラ 2 8,28が傾動して、長尺丸材 14を垂直ローラ 30,30に当接させるよう構成されていた。 しかしながら、実施例 2の下方水平ローラ 62,62については横方向の位置規制もなし 得るので、下方水平ローラ 28, 28を傾動させる必要がなぐ実施例 2の供給装置 60 には空気圧シリンダ 38が設けられて ヽな 、。 [0044] Further, the lower horizontal rollers 62, 62 are provided in the lift 34 such that each intermediate portion 62b is positioned vertically below the pass line PL. That is, the lower horizontal rollers 62 and 62 according to the second embodiment lift the long circular material 14 and press it against the upper horizontal rollers 26 and 26 to secure the upper reference surface T, and the long circular material 14 is attached to the intermediate portion 62b. , 62b is used to regulate the position of the long round material 14 in the lateral direction. Accordingly, the supply device 60 of the second embodiment is not provided with the vertical rollers 30 and 30 that perform the lateral restriction on the long circular material 14 in the first embodiment. Further, in the supply device 10 of the first embodiment, the lower horizontal rollers 28, 28 are tilted so that the long round material 14 is brought into contact with the vertical rollers 30, 30. However, since the lower horizontal rollers 62 and 62 of the second embodiment can also be regulated in the lateral direction, the pneumatic cylinder 38 is provided in the supply device 60 of the second embodiment that does not require the lower horizontal rollers 28 and 28 to be tilted. Be cunning.
[0045] なお、実施例 2におけるスロープ部材 64には、その傾斜面 64aにおける傾斜下端 側に規制部材 64bが設けられている。この規制部材 64bは、前記載置手段 48によつ てスロープ部材 64上に移動され、傾斜面 64aを転動する長尺丸材 14を、下方水平 ローラ 62,62上で停止させるよう構成される。また、図 9(a)に示すように、第 1位置に おける下方水平ローラ 62は、実施例 1と同様に、スロープ部材 64よりも下方に位置し てしている。
[0046] (実施例 2の作用) Note that the slope member 64 in the second embodiment is provided with a regulating member 64b on the inclined lower end side of the inclined surface 64a. The restricting member 64b is moved onto the slope member 64 by the mounting means 48 described above, and is configured to stop the long round material 14 rolling on the inclined surface 64a on the lower horizontal rollers 62 and 62. . Further, as shown in FIG. 9 (a), the lower horizontal roller 62 at the first position is positioned below the slope member 64, as in the first embodiment. [Operation of Example 2]
次に、実施例 2に係る供給装置 60の作用について説明する。ストック部 18に待機さ れた長尺丸材 14は、実施例 1と同様に、載置手段 48,48によってスロープ部材 64,6 4上へ移動される。スロープ部材 64,64上へ移動された長尺丸材 14は、傾斜面 64a, 64a上を規制部材 64b,64bに当接するまで転動する。この時、図 9(a)に示すように、 第 1位置にある下方水平ローラ 62,62は、スロープ部材 64,64よりも下方に位置して V、るので、該スロープ部材 64,64上の長尺丸材 14と干渉することはな!/、。 Next, the operation of the supply device 60 according to the second embodiment will be described. The long circular material 14 waiting in the stock unit 18 is moved onto the slope members 64, 64 by the mounting means 48, 48 as in the first embodiment. The elongated round member 14 moved onto the slope members 64, 64 rolls on the inclined surfaces 64a, 64a until it comes into contact with the regulating members 64b, 64b. At this time, as shown in FIG. 9 (a), the lower horizontal rollers 62 and 62 in the first position are located below the slope members 64 and 64 V, so No interference with the long round material 14! /.
[0047] 次に、前記油圧シリンダ 22が作動して昇降台 34を押し上げ、下方水平ローラ 62,6 2は上昇を始める。そして、下方水平ローラ 62,62がスロープ部材 64,64を越えると、 該スロープ部材 64,64上に載置されている長尺丸材 14が下方水平ローラ 62,62上 に移動する (図 9(b))。この時、下方水平ローラ 62,62は、その中間部分 62bが左右両 方向から略円錐状に収束しているので、長尺丸材 14は中間部分 62bに保持される。 すなわち、この時点において、長尺丸材 14は横方向の位置規制がなされる。 Next, the hydraulic cylinder 22 is actuated to push up the lifting platform 34, and the lower horizontal rollers 62, 62 begin to rise. When the lower horizontal rollers 62 and 62 exceed the slope members 64 and 64, the long round material 14 placed on the slope members 64 and 64 moves onto the lower horizontal rollers 62 and 62 (FIG. 9 ( b)). At this time, since the intermediate portion 62b of the lower horizontal rollers 62 and 62 converges in a substantially conical shape from both the left and right directions, the long round material 14 is held by the intermediate portion 62b. That is, at this time, the long circular material 14 is subjected to lateral position restriction.

The long round piece 14 is held at the same height as the upper reference plane T. The long circular material 14 is sandwiched between the lower horizontal rollers 62 and 62 and the upper horizontal rollers 26 and 26 by the urging force of the hydraulic cylinder 22. That is, according to the supply device 60 according to the second embodiment, the long round material 14 is reliably secured on the upper reference surface T and can be stably supplied to the cutting device 56. In addition, since the lower horizontal rollers 62 and 62 are configured as a central roller whose middle portion 62b is converged in a substantially conical shape from the left and right directions, the position of the long round material 14 is laterally restricted by the middle portion 62a. When supplying the cutting device 56 to the cutting device 56, the long circular material 14 is supplied stably without being displaced from the pass line PL.
