Description

本発明は、金属帯の両幅端部の切屑を行うためのサイドトリマー装置に関するものである。   The present invention relates to a side trimmer device for cutting chips at both width ends of a metal strip.

通常、鋼帯等の金属帯の製造ライン、例えば、鋼帯の酸洗ラインでは、サイドトリマー装置を用いて鋼帯の両幅端部の切屑(トリミング)を行っている(例えば、特許文献1参照。)。   Usually, in the production line of metal strips, such as steel strips, for example, the pickling line of steel strips, chips (trimming) are performed at both ends of the steel strip using a side trimmer device (for example, Patent Document 1) reference.).

従来のサイドトリマー装置では、図2(a)に側面図、図2(b)に図2(a)におけるA−A矢視図を示すように、走行する鋼帯10の両幅端部を、それぞれ上下一対の同径の回転丸刃(上トリマー刃21と下トリマー刃22)によってトリミングして、所定の幅寸法に仕上げるとともに、切屑したトリム屑13を、鋼帯10の走行ラインから下方に延びる筒状のシュート14によって、その出側下方に設けたチョッパー15に誘導し、チョッパー15にてトリム屑13を矩形に剪断するようになっている。なお、切屑したトリム屑13をチョッパー15によって剪断するのに代えて、巻取装置によってトリム屑13を巻き取る場合等もある。
特開平11−254226号公報
In the conventional side trimmer device, as shown in the side view in FIG. 2 (a) and the AA arrow view in FIG. 2 (a) in FIG. Trimming is performed by a pair of upper and lower rotating round blades having the same diameter (upper trimmer blade 21 and lower trimmer blade 22) to finish to a predetermined width dimension, and the trimmed scrap 13 is moved downward from the travel line of the steel strip 10. A cylindrical chute 14 extending in the direction leads to a chopper 15 provided on the lower side of the outlet side, and the trim scrap 13 is sheared into a rectangle by the chopper 15. In addition, instead of shearing the trimmed trim scrap 13 by the chopper 15, the trim scrap 13 may be wound up by a winding device.

図2に示すような従来のサイドトリマー装置では、トリム屑13は鋼帯10と同様に直進しようとする。そのため、鋼帯10の走行ラインから下方に延びるシュート14を用いることで、トリム屑13を物理的に下方に設置されたチョッパー15へ誘導していた。このような従来のサイドトリマー装置では、トリム屑の先端部及び板厚の厚いトリム屑といった、シュート14自体への挿入が難しいものや、シュート14の内壁に干渉しやすいものの場合、トリム屑13はチョッパー15へ到達せず、トリム屑詰りを発生させていた。   In the conventional side trimmer device as shown in FIG. 2, the trim debris 13 tends to go straight like the steel strip 10. Therefore, by using the chute 14 that extends downward from the travel line of the steel strip 10, the trim scraps 13 are guided to the chopper 15 that is physically installed below. In such a conventional side trimmer device, in the case where it is difficult to insert into the chute 14 itself, such as the tip portion of trim trim and the thick trim scrap, or the one that easily interferes with the inner wall of the chute 14, the trim scrap 13 is The chopper 15 did not reach and trim trimming was generated.

このトリム屑詰りは、その処理時のライン停止によりダウンタイムを発生させる。このダウンタイムは、例えば、5時間/月に達し、それによって、約600tの減産となって、ライン能率を大幅に低下させてしまうという問題になる。   This trim clogging causes downtime due to line stoppage during the processing. This downtime reaches, for example, 5 hours / month, which results in a reduction in production of about 600 tons and a significant reduction in line efficiency.

本発明は、上記の問題を解決するためになされたものであり、トリム屑詰りの発生を抑止し、トリム屑詰りによるダウンタイムを削減して、ライン能率を向上させることができるサイドトリマー装置を提供することを目的とするものである。   The present invention has been made in order to solve the above-described problem. A side trimmer device capable of suppressing generation of trim debris, reducing downtime due to trim debris, and improving line efficiency. It is intended to provide.

上記課題を解決するために、本発明は以下の特徴を有する。   In order to solve the above problems, the present invention has the following features.

[1]走行する金属帯の両幅端部を上トリマー刃と下トリマー刃によってトリミングし、トリミングしたトリム屑を、金属帯の走行ラインから下方に延びるシュートによって誘導して処理するサイドトリマー装置において、上トリマー刃の周速を下トリマー刃の周速より速くしたことを特徴とするサイドトリマー装置。   [1] In a side trimmer device that trims both width ends of a traveling metal strip with an upper trimmer blade and a lower trimmer blade, and guides and processes the trimmed trim scraps by a chute extending downward from the traveling line of the metal strip. A side trimmer device characterized in that the peripheral speed of the upper trimmer blade is higher than the peripheral speed of the lower trimmer blade.

[2]上トリマー刃の径を下トリマー刃の径より大きくし、上トリマー刃と下トリマー刃を同じ回転数で回転させることによって、上トリマー刃の周速を下トリマー刃の周速より速くしたことを特徴とする請求項1に記載のサイドトリマー装置。   [2] By making the diameter of the upper trimmer blade larger than the diameter of the lower trimmer blade and rotating the upper trimmer blade and the lower trimmer blade at the same rotational speed, the peripheral speed of the upper trimmer blade is made faster than the peripheral speed of the lower trimmer blade. The side trimmer device according to claim 1, wherein the side trimmer device is provided.

従来のサイドトリマー装置におけて、トリム屑が金属帯と同様に直進しようとするのは、上トリマー刃と下上トリマー刃が同径で、その周速が等速であるためである。   In the conventional side trimmer device, the trim scrap tends to go straight like the metal strip because the upper trimmer blade and the lower upper trimmer blade have the same diameter and the peripheral speed thereof is constant.

これに対して、本発明のサイドトリマー装置では、上トリマー刃の周速を下トリマー刃の周速より速くしているので、トリム屑が下方に向かって進行するようになり、スムースにシュートを経由してチョッパー等に誘導されるようになる。その結果、従来は、シュート自体への挿入が難しかったり、シュートの内壁に干渉しやすかった、トリム屑の先端部及び板厚の厚いトリム屑といったものの場合でも、トリム屑詰りの発生が抑えられる。   On the other hand, in the side trimmer device of the present invention, the peripheral speed of the upper trimmer blade is made faster than the peripheral speed of the lower trimmer blade, so that trim scraps progress downward and smoothly shoot. It will be guided to the chopper via. As a result, the occurrence of clogging of trim debris can be suppressed even in the case of the trim debris that is difficult to insert into the chute itself or interfere with the inner wall of the chute, and the trim debris has a large thickness.

本発明によれば、トリム屑詰りの発生が抑止され、トリム屑詰りによるダウンタイムが削減されて、ライン能率を向上させることができる。   According to the present invention, generation of trim debris is suppressed, downtime due to trim debris is reduced, and line efficiency can be improved.

本発明のサイドトリマー装置の一実施形態を図1に示す。図1(a)は側面図、図1(b)に図1(a)におけるA−A矢視図である。   One embodiment of the side trimmer device of the present invention is shown in FIG. Fig.1 (a) is a side view, FIG.1 (b) is an AA arrow line view in Fig.1 (a).

図1に示すように、この実施形態に係るサイドトリマー装置は、走行する鋼帯10の両幅端部を、それぞれ上下一対の回転丸刃(上トリマー刃11と下トリマー刃12)によってトリミングして、所定の幅寸法に仕上げるとともに、切屑したトリム屑13を、鋼帯10の走行ラインから下方に延びる筒状のシュート14によって、その出側下方に設けたチョッパー15に誘導し、チョッパー15にてトリム屑13を矩形に剪断するようになっている。   As shown in FIG. 1, the side trimmer device according to this embodiment trims both width end portions of a traveling steel strip 10 with a pair of upper and lower rotating round blades (upper trimmer blade 11 and lower trimmer blade 12). Then, the trimmed scrap 13 is finished to a predetermined width dimension, and the trimmed scrap 13 is guided to a chopper 15 provided on the lower side of the exit by a cylindrical chute 14 extending downward from the traveling line of the steel strip 10. The trim scrap 13 is sheared into a rectangle.

そして、この実施形態においては、上トリマー刃11の直径φ1が、下トリマー刃12の直径φ2より大きくなっており、上トリマー刃11と下トリマー刃12が同じ回転数で回転することによって、上トリマー刃11の周速が下トリマー刃12の周速より速くなるようになっている。   In this embodiment, the diameter φ1 of the upper trimmer blade 11 is larger than the diameter φ2 of the lower trimmer blade 12, and the upper trimmer blade 11 and the lower trimmer blade 12 are rotated at the same rotational speed. The circumferential speed of the trimmer blade 11 is faster than the circumferential speed of the lower trimmer blade 12.

上記のように構成したサイドトリマー装置では、上トリマー刃11の周速が下トリマー刃12の周速より速いことから、トリム屑13が下方に向かって進行するようになり、スムースにシュート14を経由してチョッパー15に誘導されるようになる。その結果、従来は、シュート14自体への挿入が難しかったり、シュート14の内壁に干渉しやすかった、トリム屑の先端部及び板厚の厚いトリム屑といったものの場合でも、トリム屑詰りの発生が抑えられる。それによって、トリム屑詰りによるダウンタイムが削減されて、ライン能率を向上させることができる。   In the side trimmer device configured as described above, since the peripheral speed of the upper trimmer blade 11 is faster than the peripheral speed of the lower trimmer blade 12, the trim debris 13 advances downward, and the chute 14 is smoothly applied. Via the chopper 15. As a result, the occurrence of clogging of trim debris is suppressed even in the case of conventional trim debris and thick trim debris that are difficult to insert into the chute 14 itself or easily interfere with the inner wall of the chute 14. It is done. Thereby, the down time due to trim clogging is reduced, and the line efficiency can be improved.

なお、この実施形態においては、同じ回転速度(回転数)で回転する上トリマー刃11と下トリマー刃12の直径を異ならすことによって、上トリマー刃11の周速が下トリマー刃12の周速より速くなるようにしているが、同径の上トリマー刃と下トリマー刃を用いて、両者の回転数を異ならすことによって、上トリマー刃の周速が下トリマー刃の周速より速くなるようにしてもよい。   In this embodiment, the peripheral speed of the upper trimmer blade 11 is changed to the peripheral speed of the lower trimmer blade 12 by differentiating the diameters of the upper trimmer blade 11 and the lower trimmer blade 12 rotating at the same rotational speed (rotation speed). Although the speed is higher, the upper trimmer blade and the lower trimmer blade with the same diameter are used to make the rotation speed of the two different so that the peripheral speed of the upper trimmer blade is faster than the peripheral speed of the lower trimmer blade. It may be.

また、この実施形態においては、切屑したトリム屑13をチョッパー15によって剪断しているが、巻取装置によってトリム屑を巻き取る場合等にも適用できることはいうまでもない。   Further, in this embodiment, the trimmed scrap 13 that has been cut is sheared by the chopper 15, but it goes without saying that it can also be applied to the case where the trimmed scrap is taken up by a winding device.

さらに、この実施形態においては、鋼帯を対象にして述べたが、アルミや銅等の他の金属帯にも適用することができる。   Furthermore, in this embodiment, although described about steel strip, it is applicable also to other metal strips, such as aluminum and copper.

図1に示した本発明の実施形態に係るサイドトリマー装置を用いて鋼帯のトリミングを行った場合(本発明例)と、図2に示した従来のサイドトリマー装置を用いて鋼帯のトリミングを行った場合(従来例)とで、トリム屑詰りによるダウンタイムの比較を行った。   When the steel strip is trimmed using the side trimmer device according to the embodiment of the present invention shown in FIG. 1 (example of the present invention), and the steel strip is trimmed using the conventional side trimmer device shown in FIG. Comparison of downtime due to clogging of trim scraps was performed in the case of performing (conventional example).

その結果、図3に示すように、従来例では5時間/月のダウンタイムであったものが、本発明例では3.5時間/月のダウンタイムとなり、月当り1.5時間(従来例比30%減)のダウンタイムを削減が可能となった。   As a result, as shown in FIG. 3, in the conventional example, the downtime of 5 hours / month is 3.5 hours / month in the example of the present invention, and 1.5 hours per month (conventional example). The downtime can be reduced by 30%.
