吹き付けるようになっている。2. Description of the Related Art A robot 100 as shown in FIG. 2 is a spray coating apparatus used for coating a coating object having a rectangular shape and a flat coating surface. This robot 1
In 00, the coating gun 200 is attached to the tip of the arm 300, and the coating material 400 is sprayed from the coating material spray port of the coating gun 200 onto the coating object 500 in a fixed spraying pattern.

ながら重ね塗りしつつ塗装するようになっている。Moreover, in the coating gun 200, as shown in FIGS. 3 and 4, the paint spray port 201 is generally located directly above one side edge 501 of the coating object 500 and the coating surface 501 of the coating object 500 and the coating material. While maintaining the distance from the spray port 201 at a predetermined distance D ′, the reciprocating motion is parallel to the one side edge 502, and the sprayed coating surface 501 of the sprayed paint 400 is applied every time the forward and backward movements are completed. The width P is the same as the half width of the spread width of P.P.

塗りすることで塗装むらがないようにしている。That is, the paint 400 sprayed from the paint spray port 201 reaches the coating surface 501 while spreading at a predetermined angle in accordance with the pattern of the paint spray port 201, so that it is directly below the paint spray port 201 and at both spread end portions. Then, the amount of the paint 400 sprayed immediately below the coating spray port 201 is inevitably large. Therefore, the uneven coating is performed by applying the coating repeatedly as described above.

が生じる。However, in recent years, there are various types of building panels or the like which are the coating objects 500, and the width of the coating object 500 sent to the robot 100 next. W'is also not necessarily constant and may not be an integral multiple of the pitch P '. In such a case, as shown in FIG.
In this case, most of the paint 400 overflows from the other side edge 502 of the object to be painted 500, which causes a problem that the non-painted part is soiled.

Method using the spray coating device provided
However, in the case of this method, it is necessary to separately provide a blocking member and an air ejection portion in the spray coating device, which increases equipment costs and removes the paint accumulated in the paint reservoir. There is also a problem with maintainability such as having to do it.

塗装部分を汚すなどの問題がない。On the other hand, the spray coating method previously proposed by the inventors of the present invention (see JP-A-7-108212).
At both ends of the coating, make the distance between the coating gun and the object to be coated shorter than at the parts other than the ends, and aim the paint spray port of the coating gun toward the center from the end of the object to be coated. At the same time, since the coating gun can be applied at the end portion at a high moving speed so that a uniform overcoating can be carried out at the end portion as well, the same method as in the above-mentioned Japanese Patent Laid-Open No. 64-22372 is used. There is no need to remove the paint that has accumulated in the reservoir, and it has excellent maintainability.Of course, even if the width of the coating object is different, the paint will stick to the outside of the coated surface and stain the non-painted part. Absent.

的としている。However, in the case of the method of Japanese Patent Laid-Open No. 7-108212, the angle of the coating gun at the end of the object to be coated,
Since the distance to the painting surface and the moving speed have to be changed, the spray painting apparatus has to have a complicated mechanism including the control system, and there is a problem that the equipment cost is increased. In view of such circumstances, the present invention provides a spray coating method and this method that do not require equipment cost and do not spray extra paint onto a non-painted portion even if the width of the object to be coated changes. It is intended to provide a spray coating device to be used.

霧口と塗装面との距離を調整するようにした。In order to achieve such an object, the spray coating method according to the present invention is arranged such that a paint spray port of a coating gun faces a coating surface of an object to be coated at a predetermined distance. , The coating gun is reciprocated in parallel with the reference line at a constant speed for a predetermined length, and the coating gun is sequentially moved in a fixed direction orthogonal to the reference line after each forward and backward movement of the coating gun. In the spray coating method of moving and applying multiple coats, the lateral movement pitch is adjusted so that the width of the coating object in the lateral movement direction is an integral multiple of the lateral movement pitch, and the adjusted lateral movement is adjusted. The distance between the paint spray port and the coating surface was adjusted so that the pitch and the half width of the spread width of the paint sprayed from the paint spray port of the coating gun were the same.

This will be described in detail with reference to the drawings. As shown in FIG.
Spray coating apparatus 1 used in the spray coating method according to the present invention
Is equipped with a painting gun 2.

できるようになっている。Like the conventional coating gun 200, the coating gun 2 is adapted to reciprocate in parallel with one side edge 52 of the object 5 to be coated as a reference line, and to be moved forward and backward. One direction orthogonal to the one side edge 52 each time it is finished,
That is, it is configured to laterally move at a predetermined pitch in the direction of the other side edge 53. Moreover, in this spray coating apparatus 1, the pitch at which the coating gun 2 moves laterally and the distance between the coating spray port 21 of the coating gun 2 and the coating surface 51 of the coating object 5 can be freely changed.
【００１３】つぎに、この吹付塗装装置１を用いた本発

法では、まず、塗装ガン２の標準横移動ピッチＰおよび
塗装ガン２の塗料噴霧口２１と塗装対象物５の塗装面５
１との標準噴霧距離Ｄとを用いて、以下に示す演算式に
よって幅Ｗの塗装対象物５に応じた実作業ピッチＰ１と
実噴霧距離Ｄ１を決定する。Next, the spray coating method according to the present invention using the spray coating apparatus 1 will be described in detail. In the method of the present invention, first, the standard lateral movement pitch P of the coating gun 2, the coating spray port 21 of the coating gun 2 and the coating surface 5 of the coating object 5 are used.
1 and the standard spray distance D are used to determine the actual work pitch P1 and the actual spray distance D1 according to the coating object 5 having the width W by the following arithmetic expression.
【００１４】なお、標準横移動ピッチＰおよび標準噴霧
距離Ｄは、塗装ガン２の塗料噴霧口２１の噴射パターン
によって決まる。 〔演算式〕 Ｗ÷Ｐ＝ｎ余りｅ ・・・（式１） （但し、ｎは送り回数、ｅの値は正負どちらでもよく、
絶対値の小さくなる方をとる。） Ｐ１＝Ｐ＋ｅ÷ｎ ・・・（式２） Ｄ１＝Ｄ×Ｐ１÷Ｐ ・・・（式３）The standard lateral movement pitch P and the standard spray distance D are determined by the spray pattern of the paint spray port 21 of the coating gun 2. [Calculation formula] W / P = n remainder e (Equation 1) (where n is the number of feeds, and the value of e may be positive or negative,
Take the smaller absolute value. ) P1 = P + e ÷ n (Equation 2) D1 = D × P1 ÷ P (Equation 3)
【００１５】すなわち、上記演算式では、式１によって
Ｐの変更率がもっとも少なくなる送り回数ｎを求めたの

がり角θが一定であるため、Ｐ１だけを変更したので
は、Ｐ１＜Ｐのときは３回塗り重ねられる部分が生じ、
Ｐ１＞Ｐのときは、１回塗りしかできない部分が生じ
る。That is, in the above arithmetic expression, the number of feeds n at which the change rate of P is the smallest is obtained by the equation 1, and then multiplied by n by the equation 2 to determine the P1 which becomes W. However, since the spread angle θ of the coating material 4 sprayed from the coating material spray port 21 is constant, if only P1 is changed, if P1 <P, there will be a portion where the coating is repeated three times.
When P1> P, there is a portion that can be applied only once.
【００１６】そこで、塗装ガン２の塗料噴霧口２１と塗
装面５１との距離を式３によって演算されたＤ１に調整
することで、塗装面５１での塗料４の広がり幅がＰ１の
２倍となるようにしている。すなわち、塗料４の広がり
幅の１／２幅とＰ１とが同一寸法となるようにしてい
る。因に、標準横送りピッチＰ＝１２５mm、標準噴霧距
離Ｄ＝６００mmの塗装ガンを有する吹付塗装装置を用い
て、幅１２７０mmおよび幅１２３０mmの塗装対象物に塗
装を行う場合、Ｐ１，Ｄ１は、以下のようになる。Therefore, by adjusting the distance between the paint spray port 21 of the coating gun 2 and the coating surface 51 to D1 calculated by the equation 3, the spread width of the coating material 4 on the coating surface 51 becomes twice P1. I am trying to become. That is, the half width of the spread width of the paint 4 and P1 are set to have the same size. By the way, when using a spray coating device having a coating gun having a standard transverse feed pitch P = 125 mm and a standard spraying distance D = 600 mm, when coating a coating object having a width of 1270 mm and a width of 1230 mm, P1 and D1 are as follows: become that way.
【００１７】〔塗装対象物の幅が１２７０mmの時〕 １２７０mm÷１２５mm＝１０余り２０mm Ｐ１＝１２５mm＋２０mm÷１０＝１２７mm Ｄ１＝６００mm×１２７mm÷１２５mm＝６０９．６mm 〔塗装対象物の幅が１２３０mmの時〕 １２３０mm÷１２５mm＝１０余り−２０mm Ｐ１＝１２５mm＋（−２０mm）÷１０＝１２３mm Ｄ１＝６００mm×１２３mm÷１２５mm＝５９０．４mm[When the width of the coating object is 1270 mm] 1270 mm ÷ 125 mm = 10 remainder 20 mm P1 = 125 mm + 20 mm ÷ 10 = 127 mm D1 = 600 mm × 127 mm ÷ 125 mm = 609.6 mm [When the width of the coating object is 1230 mm] 1230mm ÷ 125mm = 10 remainder -20mm P1 = 125mm + (-20mm) ÷ 10 = 123mm D1 = 600mm × 123mm ÷ 125mm = 590.4mm

まで塗装するようになっている。Next, in the spray coating apparatus 1, the coating gun 2 has an actual working pitch P1 and an actual spraying distance D determined by the above equation.
1 is programmed so that the paint gun 2 can be operated while keeping the same, and the paint spray port 21 of the coating gun 2 is aligned with the one side edge 52 of the object 5 to be coated, and the coating gun 2 is parallel to the one side edge 52 at a constant speed. While reciprocating at the same time, the actual work pitch P1 is laterally moved for each forward movement and backward movement, and the other side end 53 is moved.
It is supposed to be painted up to.
【００１９】すなわち、この吹付塗装方法では、実作業

る心配がない。That is, in this spray coating method, n times the actual work pitch P1 matches the width W of the object to be coated 5, so that even if objects to be coated with different widths are occasionally sent, At the time of the last painting operation 6, the paint spray port 21 always comes directly above the other side edge 53 of the object 5 to be painted. Therefore, during the first painting operation and the last painting operation,
The width of the paint 4 is equal to the width of the actual work pitch P1, that is, a half width of the spread width of the paint 4 on the coating surface 51.
Since it only sticks out, there is no need to worry about unpainted parts getting dirty.
【００２０】しかも、実作業ピッチＰ１の値に応じて、

２倍となるように実噴霧距離Ｄ１を調整したので、３回
塗り重ねられる部分や１回塗りしかできない部分がなく
全体的に均一に重ね塗りすることができる。Moreover, according to the value of the actual work pitch P1,
Since the actual spraying distance D1 was adjusted so that the spread width of the coating material 4 on the coating surface 51 was twice the actual working pitch P1, there was no portion where coating was repeated three times, and there was no portion where only one coating was possible. Can be overcoated.

い。Since the spray coating method and spray coating apparatus according to the present invention are configured as described above, even if the width of the object to be coated changes, extra paint is sprayed onto the non-painted portion. It is possible to perform uniform overcoating on the entire painted surface without any trouble. Moreover, since the operation of the device itself is simple, no complicated mechanism is required and no facility cost is required.
