Description

本発明は、フラックス裏当装置及び/又は銅板裏当装置の上に、被溶接板を仮付けした後のパネルをその溶接線が裏当装置上になるように供給し、パネルの表面側から仮付け部を片面溶接する片面溶接方法に関し、特に、複数パネルを同時に裏当装置上に供給する複数パネル片面溶接方法に関する。   The present invention supplies a panel after temporarily attaching a plate to be welded onto a flux backing device and / or a copper plate backing device so that the weld line is on the backing device, and from the surface side of the panel. More particularly, the present invention relates to a single panel welding method for supplying a plurality of panels onto a backing device at the same time.

従来の片面自動溶接装置においては、一方向に延びるトイの中にフラックスを散布供給したフラックス裏当部材又は一方向に延びる銅板を設けた銅板裏当部材(以下、双方を含めて裏当部材という)を配置し、この裏当部材上に、被溶接鋼板が仮付けされたパネルを搬送し、パネルの溶接線を裏当部材上に位置させて停止させ、その後、パネル上を溶接線に沿って裏当部材の長手方向に移動する溶接機により、被溶接板間の仮付け部を溶接する。このような片面自動溶接装置による片面自動溶接方法が特許文献1及び2に開示されている。   In a conventional single-sided automatic welding device, a flux backing member in which flux is dispersed and supplied in a toy extending in one direction or a copper plate backing member provided with a copper plate extending in one direction (hereinafter referred to as backing member including both) ) Is placed on the backing member, the panel with the steel plate to be welded is transported, the welding line of the panel is positioned on the backing member and stopped, and then the panel is moved along the welding line. Then, the tacking portion between the plates to be welded is welded by a welding machine that moves in the longitudinal direction of the backing member. Patent Documents 1 and 2 disclose a single-sided automatic welding method using such a single-sided automatic welding apparatus.

実公昭53−21616号公報Japanese Utility Model Publication No. 53-21616 特許第3526178号公報Japanese Patent No. 3526178

しかしながら、これらの特許文献1及び2に開示された片面自動溶接方法は、複数個の被溶接鋼板が仮付けされた1個のパネルを複数列の裏当装置上に供給して、そのパネルの仮付け部、即ち溶接線を溶接機により自動溶接するものであるため、パネルの配置(溶接準備)工程及び溶接工程を順次実施するものであり、必ずしも高効率で溶接できるものではなかった。   However, in the single-sided automatic welding methods disclosed in these Patent Documents 1 and 2, one panel on which a plurality of steel plates to be welded are temporarily attached is supplied onto a plurality of rows of backing devices. Since the tacking portion, that is, the welding line is automatically welded by a welding machine, the panel placement (welding preparation) step and the welding step are sequentially performed, and the welding cannot always be performed with high efficiency.

即ち、この片面自動溶接設備においては、複数列の裏当装置と複数の溶接機を配置し、パネルの複数の溶接線(3個以上の被溶接鋼板の複数の仮付け部)を同時に溶接できるものであり、例えば、5台の裏当装置が設置されていれば、溶接機も5機あれば、1パネルの5個の溶接線を同時に溶接することができる。溶接機が1機であっても、裏当装置上に配置された1パネルの5個の溶接線を1機の溶接機で順次溶接することができる。   That is, in this single-sided automatic welding equipment, a plurality of rows of backing devices and a plurality of welding machines can be arranged to simultaneously weld a plurality of panel welding lines (a plurality of tacking portions of three or more steel plates to be welded). For example, if five backing devices are installed, five welding lines in one panel can be welded simultaneously if there are five welding machines. Even if there is one welding machine, it is possible to sequentially weld five welding lines of one panel arranged on the backing device with one welding machine.

しかし、従来の片面溶接方法においては、パネルの大きさが小さい場合、つまり、例えば1パネルに1個の溶接線しかない場合(2個の被溶接鋼板の1個の仮付け部)も、同様に1パネルずつ、裏当装置上に供給されており、裏当装置は1台しか使用されず、残りの裏当装置は無駄に待機していることになる。   However, in the conventional single-sided welding method, the same applies when the panel size is small, that is, when there is only one weld line in one panel (one temporary attachment portion of two welded steel plates), for example. One panel at a time is supplied onto the backing device, and only one backing device is used, and the remaining backing devices are waiting in vain.

また、裏当装置においては、1回溶接工程が実施されると、次の溶接の準備工程が実施される。例えば、フラックス裏当装置においては、従前の溶接工程で表面が固化したフラックスを除去し、新しいフラックスを下敷用のフラックス上に散布し、パネルをその上方に搬送し、フラックス裏当部材を上昇させて、パネルの溶接線の位置に押しつけるという準備作業が実施される。よって、溶接工程と、準備工程とを交互に実施するため、溶接機は待機する時間が長く、効率的に溶接作業がなされているとはいえない。   Further, in the backing device, when the welding process is performed once, the next welding preparation process is performed. For example, in a flux backing device, the flux solidified in the previous welding process is removed, new flux is spread on the underlay flux, the panel is transported above it, and the flux backing member is raised. Then, the preparatory work of pressing against the position of the welding line of the panel is performed. Therefore, since the welding process and the preparation process are performed alternately, the welding machine has a long waiting time, and it cannot be said that the welding operation is being performed efficiently.

本発明はかかる問題点に鑑みてなされたものであって、複数個のパネルを同時に裏当装置上に供給し、溶接及びその準備を同時に実施することができ、高効率で片面自動溶接することができる複数パネル片面溶接方法を提供することを目的とする。   The present invention has been made in view of such problems, and can supply a plurality of panels onto a backing device at the same time, perform welding and preparation simultaneously, and perform high-efficiency single-sided automatic welding. An object of the present invention is to provide a method for welding a plurality of panels on one side.

本発明に係る複数パネル片面溶接方法は、一方向に延びる裏当部材を備えた複数個の裏当装置と、この裏当部材に沿って移動しその上に配置されたパネルを溶接する溶接機とを有する片面溶接装置により、複数個のパネルを並行して片面溶接する方法であって、夫々1又は複数個の被溶接板が仮付け溶接された複数個のパネルを前記裏当装置上に前記パネルの溶接線が前記裏当部材上になるように前記裏当部材の長手方向に搬送して供給し、隣接するパネル間に位置する裏当装置をそれらのパネルの側縁の支持に利用することを特徴とする。   A multiple panel single-sided welding method according to the present invention includes a plurality of backing devices including a backing member extending in one direction, and a welding machine that moves along the backing member and welds a panel disposed thereon. And a plurality of panels each having one or a plurality of plates to be welded tack-welded on the backing device. The panel is transported and supplied in the longitudinal direction of the backing member so that the weld line of the panel is on the backing member, and the backing device located between adjacent panels is used to support the side edges of those panels. It is characterized by doing.

この複数パネル片面溶接方法において、前記裏当装置上に同時に供給するパネルの数をM、各パネルの溶接線の数の総数をNとしたとき、裏当装置の台数は、(N+M−1)以上であることが好ましい。   In this multi-panel single-side welding method, when the number of panels supplied simultaneously on the backing device is M and the total number of welding lines of each panel is N, the number of backing devices is (N + M-1). The above is preferable.

また、一の期間において、前記裏当装置上に同時に供給された複数のパネルのうち、一部の第1群のパネルは前記溶接機による片面溶接を実施すると同時に、残りの第2群のパネルは前記裏当装置上で溶接の準備を行い、前記第1群のパネルの溶接が終了した後、前記第1群のパネルが前方に送出されると共に、このパネルが抜けた後の裏当装置上には次順の第1群のパネルが供給され、次順の期間において、第1群のパネルは前記裏当装置上で溶接準備がなされると同時に、前記第2群のパネルは前記溶接機による片面溶接が実施されることが好ましい。   In one period, among the plurality of panels supplied simultaneously on the backing device, a part of the first group of panels is subjected to one-side welding by the welding machine and at the same time the remaining second group of panels. Is prepared for welding on the backing device, and after the welding of the first group of panels is finished, the first group of panels is sent forward and the backing device after the panel is removed. A first group of panels in the next order is supplied on the top, and in the next period, the first group of panels are prepared for welding on the backing device, and at the same time, the second group of panels is in the welded state. It is preferable that single-side welding by a machine is performed.

前記溶接機の台数は1日当りの必要な溶接線の生産量に応じて決定されてよいが、溶接線数が最も多いパネルの溶接線数と同一以上であるか、又は前記溶接機の台数は、全てのパネルの溶接線数を加算した値以上であればより効果的である。   The number of welders may be determined according to the required production amount of weld lines per day, but is equal to or greater than the number of weld lines of the panel having the largest number of weld lines, or the number of welders is It is more effective if it is equal to or greater than the sum of the number of weld lines of all panels.

更に、前記裏当装置は、夫々2列のパネル搬送装置を有し、各裏当装置の各パネル搬送装置は、その上のパネルを前記裏当装置に沿って移動させるものであり、各裏当装置に設けられた2列のパネル搬送装置は、相互に独立して駆動可能であることが好ましい。   Further, each of the backing devices has two rows of panel conveying devices, and each panel conveying device of each backing device moves a panel on the backing device along the backing device. It is preferable that the two rows of panel conveying devices provided in the apparatus can be driven independently of each other.

本発明によれば、同時に複数パネルを片面自動溶接することができ、高効率で被溶接材を片面自動溶接することができる。また、本発明の片面溶接方法では、溶接機の稼働率を高めることができる。更に、本発明の片面溶接方法によれば、設備の設置スペースが小さくて足りるという効果がある。   According to the present invention, a plurality of panels can be automatically welded on one side at a time, and a material to be welded can be automatically welded on one side with high efficiency. Moreover, in the single-sided welding method of this invention, the operating rate of a welding machine can be raised. Furthermore, according to the single-sided welding method of the present invention, there is an effect that the installation space for the facility is small.

As shown in FIGS. 1 to 3, in this embodiment, five backing devices 1, 2, 3, 4, and 5 are installed in parallel to each other, and on both sides of these backing devices, Roller devices 6 and 7 are installed. In the embodiment shown in FIG. 1, two welded steel plates are temporarily attached to a panel 11 with one weld line, and four welded steel plates are temporarily attached to a panel 12 having three weld lines. Are conveyed in the longitudinal direction of the backing devices 1 to 5 and arranged on the backing devices 1 to 5. In this case, the panels 11 and 12 are conveyed so that each weld line thereof is positioned on one of the backing devices 1 to 5. In the embodiment shown in FIG. 2, three welded steel plates are temporarily attached to two panels 13, and similarly three welded steel plates are temporarily attached to two weld lines 14.

In the embodiment shown in FIG. 3, four welded steel plates are temporarily attached to four panels 15, and two welded steel plates are temporarily attached to one weld line. It is conveyed in the longitudinal direction of the backing devices 1 to 5 and arranged on the backing devices 1 to 5.

図4はこの片面自動溶接装置を示す図であり、図1乃至3に示す右端の裏当装置5(20)と、その右方のローラ装置7(30)を示すものである。この裏当装置20は、フラックス裏当部材21と銅板裏当部材22とが並行に設けられた2列の裏当部材を備えている。このフラックス裏当部材21と銅板裏当部材22とは、溶接方法により、いずれかが選択的に使用される。そして、これらのフラックス裏当部材21と銅板裏当部材22との間には、マグネット吸引部材29が複数個1列になって配置されており、裏当装置の上に供給されたパネルを磁力により吸引して、浮き上がらないように固定することができるようになっている。また、2列のフラックス裏当部材21と銅板裏当部材22の外側には、夫々ローラ23,24がその回転軸を裏当部材21,22の長手方向に直交させて設置されている。このローラ23,24は夫々モータ25,26により回転駆動されて、パネルを裏当部材21,22の長手方向に移動させることができる。更に、隣接するローラ23間及び隣接するローラ24間には、夫々マグネット吸引部材27,28が配置されており、マグネット吸引部材29と同様にパネルを磁力により吸引固定するようになっている。   FIG. 4 is a diagram showing this single-sided automatic welding apparatus, and shows the right end backing apparatus 5 (20) and the right roller apparatus 7 (30) shown in FIGS. The backing device 20 includes two rows of backing members in which a flux backing member 21 and a copper plate backing member 22 are provided in parallel. One of the flux backing member 21 and the copper plate backing member 22 is selectively used by a welding method. A plurality of magnet attracting members 29 are arranged in a line between the flux backing member 21 and the copper plate backing member 22, and the panel supplied on the backing device is magnetically coupled. It can be fixed so that it cannot be lifted by suction. Further, on the outside of the two rows of the flux backing member 21 and the copper plate backing member 22, rollers 23 and 24 are respectively installed with their rotation axes orthogonal to the longitudinal direction of the backing members 21 and 22. The rollers 23 and 24 are rotationally driven by motors 25 and 26, respectively, so that the panel can be moved in the longitudinal direction of the backing members 21 and 22. Further, magnet attracting members 27 and 28 are arranged between the adjacent rollers 23 and between the adjacent rollers 24, respectively, and like the magnet attracting member 29, the panel is attracted and fixed by magnetic force.

ローラ装置30は複数個のローラ31が裏当部材21,22の長手方向(パネル搬送方向)に沿って配置されている。各ローラ31はその回転軸が裏当部材21,22の長手方向に直交するように配置されており、モータ32により回転駆動されて、パネルを裏当部材21,22の長手方向に移動させることができる。   In the roller device 30, a plurality of rollers 31 are arranged along the longitudinal direction (panel transport direction) of the backing members 21 and 22. Each roller 31 is arranged so that the rotation axis thereof is orthogonal to the longitudinal direction of the backing members 21 and 22, and is rotated by the motor 32 to move the panel in the longitudinal direction of the backing members 21 and 22. Can do.

他の裏当装置1,2,3,4も、裏当装置20と同様の構造を有しており、図1〜3の左端のローラ装置6も、ローラ装置30と同様の構造を有する。なお、裏当装置1〜5はその長手方向に垂直の方向に移動することができ、各裏当装置1〜5の相互間の間隔を調整することができるようになっている。   The other backing devices 1, 2, 3, 4 have the same structure as the backing device 20, and the roller device 6 at the left end in FIGS. 1 to 3 also has the same structure as the roller device 30. The backing devices 1 to 5 can move in a direction perpendicular to the longitudinal direction thereof, and the interval between the backing devices 1 to 5 can be adjusted.

次に、上述の如く構成された片面自動溶接装置を使用して、2枚のパネルを同時に生産する方法について説明する。図1に示す第1態様においては、溶接線が1本のパネル11と、溶接線が3本のパネル12とを、矢印で示す裏当部材の長手方向に搬送し、裏当装置1〜5上に配置する。このとき、各パネル11,12の溶接線の位置を裏当装置1,3,4,5に一致させる。即ち、パネル11の1本の溶接線を、第1(No.1)裏当装置1に一致させ、パネル12の3本の溶接線を、第3(No.3)裏当装置3、第4(No.4)裏当装置4及び第5(No.5)裏当装置5に一致させるように、各パネル11,12を裏当装置上に供給する。そうすると、パネル11は、その両側縁部が、設備左端部のローラ装置6のローラ31群と、第2(No.2)裏当装置2のローラ23(図4の左方ローラ23)群とにより支持される。一方、パネル12は、その両側縁部が、第2(No.2)裏当装置2のローラ24(図4の右方ローラ24)群と、設備右端部のローラ装置7のローラ31群とにより支持される。   Next, a method of simultaneously producing two panels using the single-sided automatic welding apparatus configured as described above will be described. In the first mode shown in FIG. 1, the panel 11 having one welding line and the panel 12 having three welding lines are conveyed in the longitudinal direction of the backing member indicated by the arrows, and the backing devices 1 to 5 are used. Place on top. At this time, the positions of the welding lines of the panels 11 and 12 are made to coincide with the backing devices 1, 3, 4 and 5. That is, one welding line of the panel 11 is made to coincide with the first (No. 1) backing device 1, and three welding lines of the panel 12 are matched with the third (No. 3) backing device 3, The panels 11 and 12 are supplied onto the backing device so as to match the 4 (No. 4) backing device 4 and the fifth (No. 5) backing device 5. Then, as for the panel 11, the both-sides edge part is the roller 31 group of the roller apparatus 6 of equipment left end part, and the roller 23 (left roller 23 of FIG. 4) group of the 2nd (No. 2) backing apparatus 2. Is supported by On the other hand, the side edges of the panel 12 are a group of rollers 24 (right roller 24 in FIG. 4) of the second (No. 2) backing device 2 and a group of rollers 31 of the roller device 7 at the right end of the facility. Is supported by

このように、両側縁部がローラに支持された状態で、パネル11,12の溶接線が、パネル上で溶接線に沿って移動する溶接機により、溶接される。この場合に、1機の溶接機で、4本の溶接線を順次溶接しても良いし、3機の溶接機を使用して、パネル12の3本の溶接線を同時に溶接しても良い。なお、溶接時においては、マグネット吸引部材29,27,28により、パネルを磁力により吸引して固定しておく。これにより、ローラ23,24,31上に搬送されてきたパネルに対し、フラックス裏当部材21又は銅板裏当部材22を上昇させて、パネル11,12の下面に押し当てたときに、パネル11,12が浮き上がってしまうことを防止できる。   In this way, the welding lines of the panels 11 and 12 are welded by the welding machine that moves along the welding lines on the panels with both side edges supported by the rollers. In this case, four welding lines may be welded sequentially with one welding machine, or the three welding lines of the panel 12 may be welded simultaneously using three welding machines. . At the time of welding, the panel is attracted and fixed by magnetic force by the magnet attracting members 29, 27, and 28. As a result, when the flux backing member 21 or the copper plate backing member 22 is raised against the panel conveyed on the rollers 23, 24, 31 and pressed against the lower surface of the panels 11, 12, the panel 11 , 12 can be prevented from floating.

溶接後は、モータ25,26,32によりローラ23,24,41を回転駆動して、パネル11,12を裏当部材の長手方向に送り出して、搬出する。その後、次順のパネルを同様にモータ25,26,32によりローラ23,24,41を回転駆動して、裏当装置上に搬入する。この場合に、2個のパネル11,12を同時に移動させる必要はなく、1台の裏当装置20に対して2列のローラ23,24が配列されているので、夫々、モータ25,26を個別に駆動することにより、パネル11,12を個別に移動させることができる。   After welding, the rollers 23, 24, and 41 are rotationally driven by the motors 25, 26, and 32, and the panels 11 and 12 are sent out in the longitudinal direction of the backing member to be carried out. Thereafter, the rollers 23, 24, and 41 are rotated and driven by the motors 25, 26, and 32, and the next panel is carried onto the backing device. In this case, it is not necessary to move the two panels 11 and 12 at the same time, and since two rows of rollers 23 and 24 are arranged for one backing device 20, the motors 25 and 26 are respectively connected. By individually driving, the panels 11 and 12 can be moved individually.

このように、本実施形態の第1態様においては、パネル11とパネル12との間の裏当装置2を、パネル11,12の夫々側縁部を支持するために利用する。また、図2に示す第2態様においては、パネル13とパネル14との間の裏当装置3を、パネル13,14の夫々側縁部を支持するために利用する。更に、図3に示す第3態様においては、パネル15とパネル16との間の裏当装置4を、パネル15,16の夫々側縁部を支持するために利用する。このように、2枚のパネルの対向縁部間の裏当に使用されない裏当装置を、パネルの側縁部の支持に利用するので、同時に複数個(図示例は2個)のパネルを裏当装置上に供給することができる。このため、片面自動溶接装置の全ての裏当装置1〜5を裏当に使用するような最大パネル(図示例の場合は溶接線が5個)を溶接する場合ではないときは、2枚又は3枚以上の複数個のパネルを同時に裏当装置上に供給して、同時に溶接作業をすることができる。このため、溶接効率が著しく向上する。   Thus, in the first aspect of the present embodiment, the backing device 2 between the panel 11 and the panel 12 is used to support the side edges of the panels 11 and 12, respectively. Moreover, in the 2nd aspect shown in FIG. 2, the backing device 3 between the panel 13 and the panel 14 is utilized in order to support the side edge part of the panels 13 and 14, respectively. Furthermore, in the 3rd aspect shown in FIG. 3, the backing device 4 between the panel 15 and the panel 16 is utilized in order to support the side edge part of the panels 15 and 16, respectively. Thus, since the backing device that is not used for backing between the opposing edges of the two panels is used to support the side edges of the panel, a plurality of panels (two in the illustrated example) are simultaneously backed. It can be supplied on the device. For this reason, when it is not the case where the largest panel (5 welding lines in the example of illustration) which uses all the backing devices 1-5 of a single-sided automatic welding device for backing, it is 2 sheets or Three or more panels can be simultaneously supplied onto the backing device and simultaneously welded. For this reason, welding efficiency improves remarkably.

以上のように、本発明においては、複数個のパネルを裏当装置の裏当部材の長手方向に移動させ(供給し)、各パネルを他のパネルの状態(溶接又は搬送準備)に拘わらず、溶接することができる。そして、裏当装置に同時に供給するパネルの数は、上記実施形態のように2個に限らず、3個以上の複数個が可能である。このとき、本発明の効果を十分にえるためには、記裏当装置上に同時に供給するパネルの数をM(Mは2以上の自然数)、各パネルの溶接線の数の総数をN(Nは2以上の自然数)としたとき、裏当装置の台数は、(N+M−1)又はそれ以上であることが必要である。また、溶接機の台数は、1機でもよいが、溶接線数が最も多いパネルの溶接線数と同一の台数以上とすることにより、少なくとも、この大きな方のパネルについて、全ての溶接線を同時に溶接することができ、溶接効率が更に向上する。更に、溶接機の台数を、全てのパネルの溶接線数を加算した値以上とすることにより、全てのパネルの全ての溶接線を同時に溶接することができ、更に溶接効率が向上する。   As described above, in the present invention, a plurality of panels are moved (supplied) in the longitudinal direction of the backing member of the backing device, and each panel is irrespective of the state of other panels (welding or transport preparation). Can be welded. The number of panels supplied to the backing device at the same time is not limited to two as in the above embodiment, but may be three or more. At this time, in order to sufficiently obtain the effects of the present invention, the number of panels simultaneously supplied on the recording / reverse apparatus is M (M is a natural number of 2 or more), and the total number of weld lines of each panel is N ( When N is a natural number of 2 or more, the number of backing devices needs to be (N + M−1) or more. In addition, the number of welding machines may be one, but by making the number of welding lines equal to or greater than the number of welding lines of the panel with the largest number of welding lines, at least all of the welding lines are simultaneously applied to this larger panel. It is possible to weld, and the welding efficiency is further improved. Furthermore, by setting the number of welding machines to a value equal to or greater than the sum of the numbers of welding lines of all panels, all the welding lines of all the panels can be welded simultaneously, and the welding efficiency is further improved.

次に、溶接効率について詳細に説明する。図5は、本発明と異なり、5台の裏当装置1〜5に対して、その長手方向に直交する方向にパネル15,16(図3参照)を供給した場合を示す(横流れ方式)。このように、5台の裏当装置1〜5に対して、同時に2個のパネル15,16を供給しても、溶接工程は、前方のパネル16から行う必要がある。仮に、後方のパネル15から溶接を実施しても、前方のパネル16の溶接が終了していなければ、後方のパネル15を搬出することができない。また、複数機の溶接機を用意して、複数の溶接線を同時に溶接しようとしても、2個のパネル15,16が共に溶接を終了して、搬出された後に、次順の2個のパネルを裏当装置上に供給し、裏当装置の準備を行い、その後、溶接を行う必要があり、2個のパネルは、ペアとなって、溶接工程と、準備工程とを、繰り返すことになる。つまり、2個のパネルについて、溶接が終了した後、同時に搬出され、その後、2個のパネルが同時に搬入され、次いで、準備工程、溶接工程を実施するというように、2個のパネルは同時に移動する必要がある。なお、準備工程とは、前述の如く、フラックス裏当装置の場合は、従前の溶接で固化したフラックス(スラグ)を除去し、下敷用フラックス上に、新しいフラックスを散布し、その後、パネルを裏当装置上に搬入し、次いで、フラックス裏当部材を上昇させて、フラックス裏当部材をパネルの下面に押圧する作業である、また、銅板裏当装置の場合は、パネルを搬入し、銅板裏当部材を上昇させ、これをパネルの下面に押圧する作業である。   Next, the welding efficiency will be described in detail. FIG. 5 shows a case where the panels 15 and 16 (see FIG. 3) are supplied to the five backing devices 1 to 5 in a direction orthogonal to the longitudinal direction (cross flow system) unlike the present invention. Thus, even if two panels 15 and 16 are simultaneously supplied to the five backing devices 1 to 5, the welding process needs to be performed from the front panel 16. Even if welding is performed from the rear panel 15, the rear panel 15 cannot be carried out unless the front panel 16 has been welded. In addition, even if a plurality of welding machines are prepared and a plurality of welding lines are to be welded at the same time, the two panels 15 and 16 are both welded and unloaded. It is necessary to prepare the backing device and then perform welding, and the two panels are paired to repeat the welding process and the preparation process. . In other words, the two panels are moved simultaneously, such that the two panels are unloaded at the same time after the welding is completed, then the two panels are loaded simultaneously, and then the preparation process and the welding process are performed. There is a need to. In the case of a flux backing device, as described above, the preparatory process is to remove the flux (slag) solidified by the previous welding, spray new flux on the underlaying flux, and then back the panel. It is the work to carry on to this equipment and then raise the flux backing member and press the flux backing member against the lower surface of the panel. In the case of a copper plate backing device, carry in the panel and back the copper plate. This is an operation of raising the member and pressing it against the lower surface of the panel.

これに対し、本実施形態の場合は、図6に示すように、2個のパネル15,16を裏当装置1〜5の長手方向に移動させる(縦流れ方式)。このため、裏当装置1〜3は、パネル16の状態とは関係なく、パネル15の溶接工程及び準備工程を実施することができ、裏当装置5は、パネル15の状態とは関係なく、パネル16の溶接工程及び準備工程を実施することができる。   On the other hand, in this embodiment, as shown in FIG. 6, the two panels 15 and 16 are moved in the longitudinal direction of the backing devices 1 to 5 (longitudinal flow method). For this reason, the backing devices 1 to 3 can perform the welding process and the preparation process of the panel 15 regardless of the state of the panel 16, and the backing device 5 is independent of the state of the panel 15, The welding process and the preparation process of the panel 16 can be implemented.

即ち、図7に示すように、裏当装置の場合は、裏当装置1〜3では、パネル15を搬入する工程と、パネル15の下面に裏当部材を押圧して裏当部材を設置する工程と、溶接を実施する工程と、パネル15を搬出する工程と、次順のパネル15を搬入する工程とを繰り返し、裏当装置5では、パネル16を搬入する工程と、パネル16の下面に裏当部材を押圧して裏当部材を設置する工程と、溶接を実施する工程と、パネル16を搬出する工程と、次順のパネル16を搬入する工程とを繰り返す。この場合に、パネル15で裏当部材を設置する工程を実施している期間に、パネル16では、パネルを搬入する工程を実施し、パネル15で溶接工程を実施している期間に、パネル16では、裏当部材を設置する工程を実施する。そして、パネル15でパネル搬出工程を実施している期間に、パネル16では溶接工程を実施し、次順のパネル15を搬入する期間において、パネル16を搬出する。   That is, as shown in FIG. 7, in the case of the backing device, in the backing devices 1 to 3, the step of carrying in the panel 15, and the backing member is installed by pressing the backing member against the lower surface of the panel 15. The process, the step of performing welding, the step of carrying out the panel 15 and the step of carrying in the next panel 15 are repeated. In the backing device 5, the step of carrying in the panel 16, and the lower surface of the panel 16 The step of pressing the backing member to install the backing member, the step of performing welding, the step of carrying out the panel 16 and the step of carrying in the next panel 16 are repeated. In this case, during the period in which the process of installing the backing member is performed in the panel 15, in the panel 16, the process of carrying in the panel is performed, and in the period in which the welding process is performed in the panel 15, the panel 16 Then, the process which installs a backing member is implemented. The panel 16 carries out a welding process during the period in which the panel 15 carries out the panel carry-out process, and the panel 16 is carried out during the period in which the next panel 15 is carried in.

この場合に、溶接機が1機である場合は、パネル15の溶接が終了した後、溶接機をパネル16の上方に移動させてパネル16の溶接を実施することができ、溶接機は常時使用され、その稼動率を著しく高めることができる。これに対し、図5に示す横流れ方式の場合は、2個のパネルの溶接線を順次溶接した後、パネルの搬出工程、搬入工程及び準備工程の間、溶接機は使用されずに待機している。よって、その稼動率は低い。   In this case, when there is only one welding machine, the welding of the panel 16 can be performed by moving the welding machine above the panel 16 after the welding of the panel 15 is completed. The operating rate can be remarkably increased. On the other hand, in the case of the cross flow method shown in FIG. 5, after welding the welding lines of two panels in sequence, the welding machine is not used during the panel carry-out process, carry-in process and preparation process. Yes. Therefore, the operation rate is low.

また、本発明によれば、設備の設置スペースも小さくすることができる。図8は横流れ方式で2パネルを同時に流す場合の裏当装置の設置態様を示す平面図、図9は縦流れ方式で2パネルを同時に流す場合の裏当装置の設置態様を示す平面図である。横流れ方式で2パネルを同時に流す場合には、図8に示すように、パネル51の溶接線数に応じた3台の裏当装置41,42,43と、同じく3台の裏当装置44,45,46とを設け、この2系統のパネル搬送ラインの裏当装置に対し、夫々パネル51,52を個別に供給する。パネル52は2個の溶接鋼板を仮付け溶接した1本の溶接線をもつものであるが、溶接設備としては、最大溶接線数(この場合は3個)に合わせて2系統のパネル搬送ラインを同一の能力を有する設備にする必要があり、各系統について3台の裏当装置を設置する。よって、この2系統のパネル搬送ラインに対し、夫々、被溶接板を仮付け溶接してパネルを得るための仮付け場所と、片面溶接を実施する片面溶接場所と、溶接後の検査及び手直しを行う検査手直し場所とを設ける必要がある。   Moreover, according to this invention, the installation space of an installation can also be made small. FIG. 8 is a plan view showing an installation mode of the backing device when two panels are simultaneously flowed by the lateral flow method, and FIG. 9 is a plan view showing an installation mode of the backing device when two panels are simultaneously flowed by the vertical flow method. . When two panels are made to flow at the same time in the lateral flow mode, as shown in FIG. 8, three backing devices 41, 42, 43 corresponding to the number of welding lines of the panel 51, and three backing devices 44, 45 and 46 are provided, and the panels 51 and 52 are individually supplied to the backing devices of the two systems of panel conveyance lines. The panel 52 has one weld line obtained by tack-welding two welded steel plates, but the welding equipment includes two panel transport lines according to the maximum number of weld lines (in this case, three). Need to be installed with the same capacity, and three backing devices are installed for each system. Therefore, with respect to these two systems of panel conveyance lines, a temporary attachment place for temporarily welding the plate to be welded to obtain a panel, a single-sided welding place for performing single-sided welding, and inspection and repair after welding are performed. It is necessary to provide an inspection repair place to be performed.

これに対し、本発明のように、縦流れ方式で2パネルを同時に流す場合には、図9に示すように、1列に配置された裏当装置61、62,63,64,65に対し、パネル71,72をそのパネルの大きさに応じて所要数の裏当装置を選択して供給すれば良く、設備の設置面積を横流れ方式に比べて著しく縮小することができる。   On the other hand, when two panels are made to flow simultaneously in the longitudinal flow method as in the present invention, the backing devices 61, 62, 63, 64, 65 arranged in a single row as shown in FIG. The required number of backing devices may be selected and supplied to the panels 71 and 72 according to the size of the panels, and the installation area of the facility can be significantly reduced as compared with the lateral flow method.

最大パネル51(シーム数3)の面積をAとしたとき、常時最大パネル51を2枚生産するのであれば、横流れでも縦流れでも必要場所面積は6×Aとなり、変りない。しかし、同時最大パネル51を2枚生産するのでなく、最大パネルと小パネルを混合して流す場合を考える。小パネル面積をBとする。縦流れの場合、AとBを配置するやり方は図9の如くであったり、上下入れ替えることが可能であるから必要場所面接は3×(A+B)となる。横流れの場合、2つのラインにA,Bのどちらがくるか区別がつかないため、2つのラインともにAを流せるように準備しておかなければならない。従って、必要場所は6×Aとなり、縦流れより場所面積を大きく必要とする。   Assuming that the area of the maximum panel 51 (the number of seams 3) is A, if two sheets of the maximum panel 51 are always produced, the necessary area is 6 × A in both the horizontal flow and the vertical flow and does not change. However, let us consider a case where the maximum panel and the small panel are mixed and flowed instead of producing two simultaneous maximum panels 51. Let B be the small panel area. In the case of the longitudinal flow, the way of arranging A and B is as shown in FIG. 9 or can be switched up and down, so the required place interview is 3 × (A + B). In the case of cross flow, since it is not possible to distinguish between A and B on the two lines, both lines must be prepared so that A can flow. Therefore, the necessary place is 6 × A, and the place area is required to be larger than the longitudinal flow.

また、図8に示す横流れ方式の場合は、各パネル搬送ラインに3台の裏当装置を設置した場合には、1パネル当たりの最大溶接線数は3個に限定される。しかし、図9の縦流れ方式の場合は、裏当装置61〜65が5台であるとすれば、溶接線の数は1〜5まで可能である。従って、1パネル当たりの溶接線数を自由に選択することができ、大きなパネルから小さなパネルまで溶接することができる。更に、例えば、図9の場合には、夫々溶接線が1個の3個のパネルを同時に流すこともできる。   Further, in the case of the lateral flow method shown in FIG. 8, when three backing devices are installed in each panel conveyance line, the maximum number of weld lines per panel is limited to three. However, in the case of the longitudinal flow method of FIG. 9, if there are five backing devices 61 to 65, the number of weld lines can be 1 to 5. Therefore, the number of welding lines per panel can be freely selected, and welding from a large panel to a small panel can be performed. Further, for example, in the case of FIG. 9, three panels each having one weld line can be made to flow simultaneously.

なお、横流れ方式の場合には、裏当装置と溶接機とが夫々1台あれば、パネルの溶接線本数に拘わらず、片面自動溶接することができる。しかし、例えば、1パネルの溶接線が3個の場合、図10に示すように、片面溶接場所において、先ず1番目の溶接線を溶接するために、パネル80は裏当装置81に対し、図10(a)に示す位置にて停止する。次に、2番目の溶接線を溶接するために、パネル80は図10(b)に示す位置に移動する。次に、3番目の溶接線を溶接するために、パネル80は図10(c)に示す位置に移動する。そうすると、この片面溶接場所において、パネル80の移動方向について、被溶接鋼板の6枚分の長さが必要である。従って、パネルにすると、6/4=1.5であるから、パネル80の移動方向について、1.5個分必要である。図8において裏当装置3台(41,42,43)あれば、片面溶接場所はAでよいが、裏当装置が1台であると片面溶接場所は1.5×Aとなり、必要場所面積が増えて、合計2×3.5×Aとなる。   In the case of the transverse flow method, if there is one backing device and one welding machine, one-side automatic welding can be performed regardless of the number of welding lines on the panel. However, for example, when there are three welding lines for one panel, as shown in FIG. 10, the panel 80 is connected to the backing device 81 in order to weld the first welding line at a single-side welding place. Stop at the position shown in 10 (a). Next, in order to weld the second weld line, the panel 80 moves to the position shown in FIG. Next, in order to weld the third weld line, the panel 80 moves to the position shown in FIG. If it does so, in this single-sided welding place, about the moving direction of the panel 80, the length for 6 sheets of a to-be-welded steel plate is required. Therefore, in the case of a panel, since 6/4 = 1.5, 1.5 pieces are required in the moving direction of the panel 80. In FIG. 8, if there are three backing devices (41, 42, 43), the single-side welding location may be A, but if there is one backing device, the single-side welding location is 1.5 × A, and the required area Increase to a total of 2 × 3.5 × A.

これに対し縦流れの場合は融通性があり、面積も狭くて済む。しかし、縦流れ方式の場合には、図9に示すように、片面溶接場所のパネル移動方向の所要長さはパネルの大きさと実質的に同等である。   On the other hand, in the case of longitudinal flow, there is flexibility and the area can be small. However, in the case of the longitudinal flow method, as shown in FIG. 9, the required length in the panel moving direction at the single-sided welding location is substantially equal to the size of the panel.
