きくなるという欠点があつた。(Problems to be Solved by the Invention) As described above, the above-mentioned conventional coating machine is equipped with a rotary high-pressure pump 2 in the tank 1 and passes high-pressure paint through the pressure feed pipe 3, heater 4, and over device 5. Since it had to be made with a strong structure using materials with high pressure resistance, it had the drawbacks of high manufacturing costs and heavy weight.
ロ 考案の構成
（問題点を解決するための手段）
この考案は、吸込み作用の大きな往復動式高圧
ポンプをヒータの後に置くことにより、ヒータに
高圧が作用しないようにして、ヒータや高圧ポン
プに致る管の耐圧強度を大きくしなくて済むよう
に道路区画線塗装機を構成したものである。B. Composition of the invention (Means for solving the problem) This invention places a reciprocating high-pressure pump with a large suction action after the heater, thereby preventing high pressure from acting on the heater and the high-pressure pump. The road marking line painting machine is constructed so that the pressure resistance of the pipes to be painted does not need to be increased.
（作用）
吸込み作用の大きな往復動式高圧ポンプを使用
するため、ヒータを高圧ポンプの吸込側に位置さ
せることができヒータには外から大気圧が作用す
るだけなので、耐圧強度を著しく大きくする必要
がなくなる。(Function) Since a reciprocating high-pressure pump with a large suction action is used, the heater can be located on the suction side of the high-pressure pump, and only atmospheric pressure acts on the heater from the outside, so it is necessary to significantly increase pressure resistance. disappears.
（実施例）
第１図は本考案の実施例を略示する。第２図の
従来例と同等部分には同符号を用いてこれを説明

タ４に通じており、ヒータ４で加熱されて粘度の
下つた塗料は往復動式高圧ポンプ１０に吸込まれ
る。(Embodiment) FIG. 1 schematically shows an embodiment of the present invention. To explain this, using the same reference numerals for the same parts as in the conventional example shown in FIG. The paint, which has been heated by the heater 4 and whose viscosity has decreased, is sucked into the reciprocating high-pressure pump 10.
ポンプ１０から80〜100Kg／cm2の高圧で吐出さ
れた塗料は、サージタンク１１により整圧され、
過器５を経てスプレガン６に送られ、従来同様
に区画線塗装が行なわれる。逃し弁７、戻り管８
は、従来通りに設けられる。 The paint discharged from the pump 10 at a high pressure of 80 to 100 kg/cm 2 is regulated in pressure by the surge tank 11.
It is sent to a spray gun 6 via a filter 5, and marking lines are painted in the same manner as in the conventional art. Relief valve 7, return pipe 8
are provided in the conventional manner.
往復動式高圧ポンプは、従来使用された回転式
高圧ポンプ２に比べて吸込圧を著しく低くするこ
とがでるので、ヒータ４を通してタンク１内の塗
料を十分に吸込むことができる。 Since the reciprocating high-pressure pump can significantly lower the suction pressure than the conventionally used rotary high-pressure pump 2, the paint in the tank 1 can be sufficiently sucked through the heater 4.
従つてヒータ４を高圧の吐出側に設けたり、ヒ
ータを通して塗料を高圧ポンプに到達させるため
に補助の低圧ポンプを設けたりする必要がなくな
る。 Therefore, there is no need to provide the heater 4 on the high-pressure discharge side or to provide an auxiliary low-pressure pump to allow the paint to reach the high-pressure pump through the heater.
ハ 考案の効果
(1) ヒータ４を往復動式高圧ポンプ１０の吸込側
に設けるから、ヒータ４の耐圧強度は外からの
大気圧に耐えれば足りるので、従来のようにこ
れを著しく高くする必要がない。C. Effects of the invention (1) Since the heater 4 is provided on the suction side of the reciprocating high-pressure pump 10, the pressure resistance of the heater 4 is sufficient as long as it can withstand external atmospheric pressure, so there is no need to make it significantly higher than in the past. There is no.
(2) 従つてヒータ４の製作費を低廉にし、重量を
小さくすることができる。(2) Therefore, the manufacturing cost of the heater 4 can be reduced and the weight can be reduced.
重量軽減は、車載して移動しつつ塗装作業を
行なう道路区画線塗装機において重要な要素で
ある。 Reducing weight is an important factor in road marking painting machines that are mounted on vehicles and perform painting work while moving.
(3) 往復動式高圧ポンプ１０を使用するので、整
圧のためサージタンク１１を使用するが、その
ための費用、重量増加は従来の構造に比べて小
さくて済む。(3) Since the reciprocating high-pressure pump 10 is used, a surge tank 11 is used for pressure regulation, but the cost and weight increase due to this are smaller than in the conventional structure.
