このような場合に、本発明のキズ防止用治具１を用いて、例えば、搬送時に、ソーチャージテーブル３６上で並列する円管状や円柱状の押出材２同士が接触して傷つくことを防止する。   In such a case, using the jig 1 for preventing scratches of the present invention, for example, during transportation, the tubular or cylindrical extruded members 2 arranged in parallel on the saw charge table 36 are prevented from coming into contact with each other and being damaged. To do.

（キズ防止用治具）
図１〜３に示すように、キズ防止用治具１は、複数の接触防止板１１と、連結部１２を備え、押出設備３において用いられている。 (Scratch prevention jig)
As shown in FIGS. 1 to 3, the flaw prevention jig 1 includes a plurality of contact prevention plates 11 and a connecting portion 12, and is used in the extrusion equipment 3.

接触防止板１１は、押出材２で挟み込まれるように、並列する前記押出材２の間に配置される。連結部１２は、隣接する前記接触防止板１１同士を前記押出材２の上方で連結する。   The contact prevention plate 11 is disposed between the extruded materials 2 arranged in parallel so as to be sandwiched between the extruded materials 2. The connecting portion 12 connects the contact preventing plates 11 adjacent to each other above the extruded material 2.

図１に示すように、例えば、５枚の平行する接触防止板１１が、２本の帯状に形成された連結部１２によって、隣接する接触防止板１１上面の前方および後方のそれぞれで連結されている。このような構成により、押出材２同士の接触を確実に防ぐとともに、連結部１２のコストをより低減することができるようになる。   As shown in FIG. 1, for example, five parallel contact prevention plates 11 are connected to the front and rear of the upper surface of the adjacent contact prevention plates 11 by two connecting portions 12 formed in a belt shape. Yes. With such a configuration, it is possible to reliably prevent contact between the extruded materials 2 and further reduce the cost of the connecting portion 12.

図１〜３によれば、接触防止板１１は、接触防止板１１上面側で連結部１２により連結されているが、接触防止板１１の側面側で連結部１２により連結されているのであってもよい。   According to FIGS. 1 to 3, the contact prevention plate 11 is connected by the connection portion 12 on the upper surface side of the contact prevention plate 11, but is connected by the connection portion 12 on the side surface side of the contact prevention plate 11. Also good.

接触防止板１１は、例えば、ＭＣナイロンなどの合成樹脂や、カーボン板或いはカーボン紙などのカーボン素材など、押出材２と接触してもキズが比較的付き難い素材を採用する。連結部１２は、例えば、布などの可撓性を有する材料で形成される。また、連結部１２は、押出材２の幅寸法と等しい或いは略等しい間隔で接触防止板１１を連結するように構成されている。   For the contact prevention plate 11, for example, a material that is relatively difficult to be damaged even if it comes into contact with the extruded material 2, such as a synthetic resin such as MC nylon or a carbon material such as a carbon plate or carbon paper, is used. The connecting portion 12 is formed of a flexible material such as cloth. Moreover, the connection part 12 is comprised so that the contact prevention board 11 may be connected with the space | interval equal to or substantially equal to the width dimension of the extruded material 2.

このように、接触防止板１１は押出材２の幅寸法と同等或いは略同等に配置されることになるので、キズ防止用治具１装着時の各押出材２の配置間隔は、接触防止板１１の厚みと同等或いは略同等に設定されることになる。   Thus, since the contact prevention plate 11 is arrange | positioned equivalent to the width dimension of the extrusion material 2, the arrangement | positioning space | interval of each extrusion material 2 at the time of mounting | wearing the crack prevention jig 1 is a contact prevention plate. The thickness is set to be equal to or substantially equal to the thickness of 11.

キズ防止用治具１は、押出材２で挟み込むようにして接触防止板１１を押出材２間に配置し、連結する接触防止板１１間で撓んでいた連結部１２が接触防止板１１の自重で押出材２上方に覆い被さるようにして押出材２に装着される。   In the scratch prevention jig 1, the contact prevention plate 11 is disposed between the extrusion materials 2 so as to be sandwiched between the extrusion materials 2, and the connecting portion 12 bent between the contact prevention plates 11 to be connected is the weight of the contact prevention plate 11. Then, it is attached to the extruded material 2 so as to cover the extruded material 2.

キズ防止用治具１は、３つ以上の前記接触防止板１１を備えることが好ましい。３つ以上の接触防止板１１を備えることで、並列する押出材２の左右両外側に配置される各押出材２についてもキズ防止用治具１で保護するのである。押出材２の左右両外側に配置された接触防止板１１によって、並列する複数の押出材２を整列させることができので、搬送時に外側に配置された押出材２が外側に逃げることがなく、効率的に搬送することができるようになる。   The scratch prevention jig 1 preferably includes three or more of the contact prevention plates 11. By providing three or more contact prevention plates 11, the extrusion materials 2 arranged on the left and right outer sides of the parallel extrusion materials 2 are also protected by the scratch prevention jig 1. Since the plurality of juxtaposed extruding materials 2 can be aligned by the contact prevention plates 11 arranged on the left and right outer sides of the extruding material 2, the extruding material 2 arranged on the outside does not escape to the outside during transportation. It becomes possible to convey efficiently.

尚、キズ防止用治具１の押出材２への装着は、装置を介するのであってもよいし、人為的に装着されるのであっても良い。   Note that the scratch prevention jig 1 may be attached to the extruded material 2 through an apparatus or may be artificially attached.

接触防止板１１の高さは、前記押出材２の高さ寸法の半分以上に設定されることが好ましい。押出材２の高さ寸法の半分以上の高さの接触防止板１１で構成されることで、接触防止板１１が円管状や円柱状の押出材２の最大幅位置に接触防止板１１が確実に配置され、押出材２同士の接触を確実に防ぐことができるようになる。また、接触防止板１１が確実に押出材２の最大幅位置に配置されるように連結部１２の長さを調節する必要がなく、連結部１２の長さを必要最低限の長さに設定することができるようになり、押出材２への装着が容易になる。   It is preferable that the height of the contact prevention plate 11 is set to be half or more of the height dimension of the extruded material 2. By comprising the contact prevention plate 11 having a height that is at least half the height of the extruded material 2, the contact prevention plate 11 is reliably located at the maximum width position of the tubular or cylindrical extrusion material 2. It becomes arrange | positioned by this, and comes to be able to prevent reliably the contact of the extrusion materials 2 mutually. Further, it is not necessary to adjust the length of the connecting portion 12 so that the contact prevention plate 11 is surely disposed at the maximum width position of the extruded material 2, and the length of the connecting portion 12 is set to the minimum necessary length. It becomes possible to attach to the extruded material 2.

また、接触防止板１１の高さは、前記押出材２の高さ寸法と略同等或いは高さ寸法より低いことが望ましく、前記押出材２の高さ寸法より低いことがより望ましい。この構成によれば、接触防止板１１の高さが押出材２の高さ寸法より低く設定されるので、接触防止板１１の底部などが搬送テーブルに接触して押出材２の移送に影響するようなことがない。搬送テーブルに備える各搬送ローラの間隔が接触防止板１１の幅寸法より広く設定されている場合であっても、接触防止板１１が搬送ローラ間に嵌ることなく押出材２を移送させることができ、搬送テーブルの設計に自由度を持たせることもできる。また、押出材２同士の接触を確実に防ぐとともに、接触防止板１１のコストを低減することができる。   The height of the contact prevention plate 11 is preferably substantially the same as or lower than the height dimension of the extruded material 2, and more desirably lower than the height dimension of the extruded material 2. According to this configuration, since the height of the contact prevention plate 11 is set lower than the height dimension of the extruded material 2, the bottom portion of the contact prevention plate 11 comes into contact with the transport table and affects the transfer of the extruded material 2. There is no such thing. Even when the interval between the conveyance rollers provided in the conveyance table is set wider than the width of the contact prevention plate 11, the extruded material 2 can be transferred without the contact prevention plate 11 being fitted between the conveyance rollers. In addition, a degree of freedom can be given to the design of the transfer table. Further, it is possible to reliably prevent contact between the extruded materials 2 and reduce the cost of the contact prevention plate 11.

（キズ防止方法）
図４〜７に示すように、押出後面設備で搬送される押出材２は、ソーチャージテーブル３６上に並列して載置された後に、複数の押出材２が同時に切断機３７で切断される。搬送方向Ｃに長く形成された押出材２は、切断機３７まで搬送されて所定長さに切断されるのである。 (Scratch prevention method)
As shown in FIGS. 4 to 7, the extruded material 2 conveyed by the extrusion rear surface equipment is placed in parallel on the saw charge table 36, and then the plurality of extruded materials 2 are simultaneously cut by the cutting machine 37. . The extruded material 2 formed long in the conveyance direction C is conveyed to the cutting machine 37 and cut into a predetermined length.

接触防止板１１は、複数の押出材２間で挟み込まれるようにして配置される。接触防止板１１の長さは、前記押出材２の長さより短く設定され、押出材２の間で複数に離間して配置されている。   The contact prevention plate 11 is disposed so as to be sandwiched between the plurality of extruded materials 2. The length of the contact prevention plate 11 is set to be shorter than the length of the extruded material 2, and is arranged so as to be separated from the extruded material 2 by a plurality.

ソーチャージテーブル３６に所定数の押出材２が並列すると、キズ防止用治具１が装着される。押出材２は、複数に配置された前記接触防止板１１間で切断されるように構成されている。   When a predetermined number of extruded members 2 are arranged in parallel on the saw charge table 36, the scratch prevention jig 1 is mounted. The extruded material 2 is configured to be cut between the contact prevention plates 11 arranged in a plurality.

図５に示すように、例えば、押出材２を長さＬで切断する場合に、切断長さＬ内において長さ方向に離間した状態でキズ防止用治具１を配置する。押出材２の長さＬの切断後の各両端部側にキズ防止用治具１を予め配置しておけば、切断処理などの際に押出材２が移動してしまうなどの問題が生じることなく、積込テーブル３８へ押出材２を搬送することができる。   As shown in FIG. 5, for example, when the extruded material 2 is cut at a length L, the scratch-preventing jig 1 is arranged in a state of being separated in the length direction within the cut length L. If the scratch-preventing jigs 1 are arranged in advance on both ends of the extruded material 2 after the length L is cut, problems such as movement of the extruded material 2 occur during the cutting process. The extruded material 2 can be conveyed to the loading table 38.

このように、押出材２を接触防止板１１で保護したまま切断処理を行い、そのままの状態で積込テーブル３８に押出材２を搬送することができるので、より確実に押出材２同士の接触による接触キズから保護することができ、かつ効率的に作業を進めることができるようになる。   In this manner, the extrusion material 2 can be cut while being protected by the contact prevention plate 11, and the extrusion material 2 can be conveyed to the loading table 38 as it is, so that the extrusion materials 2 can be contacted more reliably. It is possible to protect from contact scratches caused by the above and to work efficiently.

また、このようにして押出材２が切断されるので、搬送時に外側に配置された押出材２が外側に逃げることなく全ての押出材２を整列させることができるので、切断機３７を通過して処理される際にも、押出材２が並列する幅を最小幅に設定することができる。   Further, since the extruded material 2 is cut in this way, all the extruded materials 2 can be aligned without causing the extruded material 2 disposed outside during transportation to escape to the outside. In the processing, the width in which the extruded materials 2 are arranged in parallel can be set to the minimum width.

上述したように、本発明のキズ防止方法によれば、押出材２同士の接触を防ぐとともに、押出材２の並列する幅を最小限に抑えることで下流側に備えた切断機３７での切断効率が向上するようになる。   As described above, according to the scratch prevention method of the present invention, cutting with the cutting machine 37 provided on the downstream side is prevented by minimizing the parallel width of the extruded materials 2 while preventing contact between the extruded materials 2. Efficiency will be improved.

こうして切断機３７で切断された押出材２は、キズ防止用治具１を装着したままの状態で第８搬送テーブル３８２に移載されて、積込テーブル３８近傍の作業員によってキズ防止用治具１が取り外される。   The extruded material 2 thus cut by the cutting machine 37 is transferred to the eighth transport table 382 with the scratch prevention jig 1 mounted, and an operator in the vicinity of the loading table 38 performs the scratch prevention treatment. The tool 1 is removed.

このように、押出材２にキズ防止治具１を装着したソーチャージテーブル３６から積込テーブル３８まで搬送する間は、確実に押出材２を接触キズから保護することができるようになるのである。   In this way, while the extruded material 2 is transported from the saw charge table 36 having the scratch prevention jig 1 mounted thereon to the loading table 38, the extruded material 2 can be reliably protected from contact scratches. .

上述したキズ防止用治具を用いることによって、複数の押出材２の並列状態での移送において、並列する前記押出材２の間に、前記押出材２の上方で連結部１２によって連結された接触防止板１１を配置するキズ防止方法が行われる。   By using the above-described scratch prevention jig, in the transfer of a plurality of extruded materials 2 in parallel, the contacts connected by the connecting portion 12 above the extruded materials 2 between the extruded materials 2 arranged in parallel. A scratch prevention method for arranging the prevention plate 11 is performed.

また、上述したキズ防止用治具１を用いることにより、押出機３１から押し出された複数の押出材２が並列状態で移送される押出設備３において、並列する前記押出材２の間に配置される複数の接触防止板１１と、前記押出材２の上方で前記接触防止板１１を連結する連結部１２と、を備えるキズ防止用治具１によって前記押出材２が保護された状態で、前記押出機３１から押し出された前記押出材２を搬送する押出方法が行われる。   Further, by using the above-described scratch prevention jig 1, the plurality of extruded materials 2 extruded from the extruder 31 are arranged between the extruded materials 2 that are juxtaposed in the extrusion equipment 3 that is transferred in a parallel state. In a state where the extrudate 2 is protected by a scratch prevention jig 1 comprising a plurality of contact preventive plates 11 and a connecting portion 12 for connecting the contact preventive plate 11 above the extrudate 2. An extrusion method for conveying the extruded material 2 extruded from the extruder 31 is performed.

キズ防止方法及び押出方法によって、複数の接触防止板１１が押出材２の間に配置されることで押出材２同士の接触を防ぎ、接触によるキズのない押出材２を製造できるようになる。   By arranging the plurality of contact prevention plates 11 between the extruded materials 2 by the scratch preventing method and the extrusion method, the extruded materials 2 can be prevented from contacting each other, and the extruded material 2 free from scratches due to contact can be produced.

さらに、上述したキズ防止用治具１を用いることにより、前記押出材２の長さ寸法より短く設定され、並列する前記押出材２の間に配置される複数の接触防止板１１と、前記押出材２の上方で前記接触防止板１１を連結する連結部１２とを備えた複数のキズ防止用治具１が前記押出材２の押出し方向に対して離間して配置され、前記キズ防止用治具１によって並列する前記押出材２が保護された状態で、前記押出材２が前記キズ防止用治具１間で切断される押出材２の切断方法が行われる。これにより、キズ防止用治具１で保護したまま押出材２の切断処理を行い、キズ防止用治具１を押出材２に装着したままの状態で下流側へ移送することができるので、より確実に押出材２を接触キズから保護することができ、かつ効率的に作業を進めることができるようになる。   Furthermore, by using the above-described scratch prevention jig 1, a plurality of contact prevention plates 11 which are set shorter than the length of the extruded material 2 and are arranged between the extruded materials 2 arranged in parallel, and the extrusion A plurality of scratch-preventing jigs 1 including a connecting portion 12 that connects the contact-preventing plate 11 above the material 2 are arranged apart from each other in the extrusion direction of the extruded material 2, and the scratch-preventing treatment In a state where the extruded materials 2 arranged in parallel by the tool 1 are protected, the extruded material 2 is cut between the scratch preventing jigs 1. As a result, the extrusion material 2 can be cut while being protected by the scratch prevention jig 1 and transferred to the downstream side while the scratch prevention jig 1 is mounted on the extrusion material 2. The extruded material 2 can be reliably protected from contact scratches, and the work can be efficiently performed.

上述の説明では、押出機３１から押し出された複数の押出材２が並列状態で下流側へ移送される押出設備３及び押出後面設備において、キズ防止治具によって保護された押出材を搬送ローラ上で下流側へ搬送するように説明したが、押出材を移送或いは搬送する場面においてキズ防止治具を用いることができる。例えば、押出材２がベルトコンベア上で移送或いは搬送される場合にキズ防止治具を用いて押出材２を接触キズから保護するのであってもよい。   In the above description, in the extrusion equipment 3 and the extrusion rear equipment in which the plurality of extruded materials 2 extruded from the extruder 31 are transferred in a parallel state to the downstream side, the extruded material protected by the scratch prevention jig is placed on the transport roller. However, in the scene where the extruded material is transferred or transported, a scratch prevention jig can be used. For example, when the extruded material 2 is transferred or conveyed on a belt conveyor, the extruded material 2 may be protected from contact scratches using a scratch prevention jig.

以上説明したように、少なくとも２本の帯状の連結部１２によって、接触防止板１１上面の前方および後方のそれぞれで連結される構成が好ましいが、一つの連結部１２によって接触防止板１１が連結されて構成されるのであってもよい。   As described above, it is preferable that the contact prevention plate 11 is connected to the front and rear of the upper surface of the contact prevention plate 11 by at least two belt-like connection portions 12, but the contact prevention plate 11 is connected by one connection portion 12. It may be configured.

例えば、図８（ａ）に示すように、隣接する接触防止板１１の上面側同士が幅広の１本の帯状の連結部１２によって連結されるのであってもよい。   For example, as shown to Fig.8 (a), the upper surface sides of the adjacent contact prevention board 11 may be connected by one wide strip | belt-shaped connection part 12. As shown in FIG.

また、少なくとも３つ以上の前記接触防止板１１を備えることが好ましいが、図８（ｂ）に示すように、並列する押出材２の最も外側に配置された押出材２の外側に接触防止板１１を配置しないように構成するのであってもよい。   Moreover, although it is preferable to provide the said contact prevention board 11 of at least 3 or more, as shown in FIG.8 (b), as shown in FIG.8 (b), a contact prevention board is outside the extrusion material 2 arrange | positioned at the outermost side. 11 may not be arranged.

このように、図８（ａ），（ｂ）に示すように構成することでも押出材２同士の接触キズを防止することができる。   In this manner, contact scratches between the extruded materials 2 can also be prevented by configuring as shown in FIGS. 8A and 8B.

以上説明した実施形態は、本発明の一例に過ぎず、本発明の作用効果を奏する範囲において具体的構成などを適宜変更設計できることは言うまでもない。   The embodiment described above is merely an example of the present invention, and it is needless to say that the specific configuration and the like can be appropriately changed and designed within the scope of the effects of the present invention.
