Compressed air passes through the inside of the nailer machine body (3) from the air supply mouthpiece (1) and enters the rear part of the cylinder (4).
0) advances in the guide pipe (6) and pushes out the push pin (10).
When the attached piston (8) advances to form the constriction (9) of the push-out pin (10) as shown by the chain line in FIG. 3, the tip end portion of the guide pipe (6) is, for example, a weir board for concrete formwork or the like. A nail which protrudes by an appropriate length such as 12 mm in thickness of the plate (11), and the projecting portion thereof is projected into the nail hole (13) of the plate (11) and is driven into the nail hole (13). (1
2) is formed by extrusion. Then, when the trigger (7) is released, compressed air enters the front part of the cylinder (4) contrary to the above, and the piston (8) with the push pin (10) retracts as shown by the dotted line in FIG. The extruded pin (10) has a constricted tip (9) formed in the base of the guide pipe (6).

る。Next, when the trigger (7) is pulled, the piston (8) with the push-out pin (10) is moved forward by the compressed air and the push-out pin (10) moves the nail (12) into the guide pipe (6) and the nail hole (13). 7, the tip of the push-out pin (10) projects from the guide pipe (6) into the nail hole (13) and is pushed by the push-out pin (10) as shown in FIG. Is extruded from the inside of the nail hole (13), and the nail (12) projects downward from the plate (11) for nail removal work.
その後、引き金（７）を離放すると、圧縮空気により押
出しピン（１０）付きピストン（８）が上記と反対に後
退し、第３図に点線で示す状態に復帰して保持される。Then, when the trigger (7) is released, the compressed air causes the piston (8) with the push-out pin (10) to retreat in the opposite direction to the above, and returns to the state shown by the dotted line in FIG. 3 and is held.
上記操作を各板（１１）の釘（１２）毎に繰返し行つて
釘仕舞いをする。The above operation is repeated for each nail (12) of each plate (11) to finish the nail operation.
なお、押出しピン（１０）のくびれ（９）は、上記の同
一太さに代え、先端側が小径の円錐状等に形成したり、
または設けなくても上記と同様に作用する。The constriction (9) of the push-out pin (10) may be formed in a conical shape having a small diameter on the tip side, instead of the same thickness as described above.
Even if it is not provided, the same operation as above is performed.
一方、上記案内パイプ（６）は実施態様の構成に限定さ

（発明の効果） この発明の釘抜き方法およびその釘抜き機は、下記のよ
うな顕著な効果を有する。(Effect of the Invention) The nail pulling method and the nail pulling machine of the present invention have the following remarkable effects.
（１）釘抜き機が圧縮空気利用のガン式で、これにより
コンクリート型枠用堰板等に打込まれたまま残つている
釘の抜取り作業を行う。従つて、 （イ）釘抜き作業を機械的に行うから、作業の効率が良
い上に、労力を軽減して省力化が図れる。(1) The nail puller is a gun type that uses compressed air, and with this, pulling out the nails that have remained driven into the concrete form dams and the like is performed. Therefore, (a) the nail removing work is performed mechanically, so that the work efficiency is high, and the labor is reduced to save labor.
（ロ）機械が軽量小型であるから、取扱い易くて女の人
でも十分に作業することができる。(B) Since the machine is lightweight and compact, it is easy to handle and a woman can work sufficiently.
（ハ）釘抜き機本体を握持して引き金を引くだけで作業
できるから、操作し易い。(C) It is easy to operate because it can be done by simply grasping the nail puller body and pulling the trigger.
（２）大きくて重い板を一方向に置いたままで裏返しす
ることなくワンタツチで釘抜き作業ができるから、手間
が省け、労力と時間を節減して作業能率を向上する。(2) Since a large and heavy plate can be left in one direction and the nail can be removed by one-touch without turning it over, labor is saved, labor and time are saved, and work efficiency is improved.
（３）押出しピンが移動する案内パイプの先端口縁部を
先端側が薄肉になるテーパーに形成してその案内パイプ
を釘の突出部に差込む。従つて、 （イ）突出部が折れ曲つて板にくつついた状態の釘で
も、容易に案内パイプの先端側が薄肉の先端口縁部によ
り釘の先端部をすくい上げて釘の突出部を案内パイプ内
に収めることができるから、釘の突出部のすくい取りを
常に容易迅速に行つて作業性が良い。(3) The leading edge portion of the guide pipe on which the pushing pin moves is formed into a taper with a thin tip side, and the guide pipe is inserted into the protruding portion of the nail. Therefore, (a) Even with a nail in which the protruding portion is bent and is being plucked into a plate, the tip end side of the guide pipe can be easily scooped up by the thin tip rim to guide the protruding portion of the nail to the guide pipe. Since it can be stored inside, scooping out the protruding portion of the nail is always easy and quick, and workability is good.
（ロ）機械をこじ上げてその案内パイプを板の面と直角
方向になすと、案内パイプにより釘を真直ぐに起こすこ
とができてその操作を容易迅速且つ適確に行うことがで
きる。(B) When the machine is lifted up and the guide pipe is formed in the direction perpendicular to the plane of the plate, the nail can be straightened by the guide pipe, and the operation can be performed easily, quickly and accurately.
（４）釘の突出部を案内パイプ内に収納して釘抜き機を
こじ上げ、釘を真直ぐに起こして押出しピンにより押出
して取去る。従つて、 （イ）常に釘を確実迅速に起こすことができる。(4) The protruding portion of the nail is housed in the guide pipe and the nail pulling machine is lifted up to raise the nail straightly and push it out with the push pin to remove it. Therefore, (a) the nail can always be raised surely and quickly.
（ロ）釘を押出しピンで押出すとき、釘は案内パイプお
よびその釘打込みの釘孔により適確に支持されて押出さ
れるから、曲つている釘でも確実に押出し取去ることが
できて作業上有益である。(B) When the nail is pushed out by the push-out pin, the nail is properly supported and pushed out by the guide pipe and the nail hole for driving the nail, so that even bent nails can be pushed out surely and removed. Above is beneficial.
（５）押出しピンは案内パイプ内および釘孔内を移動す
るため、その押出しピンの支持は確実である。(5) Since the push-out pin moves in the guide pipe and the nail hole, the support of the push-out pin is reliable.
（６）押出しピンが案内パイプより突出して板の釘孔内
に突入してその釘孔に打込まれている釘を押出して取去
るから、常に釘抜き作業を適確に行うことができる。(6) Since the push-out pin projects from the guide pipe and projects into the nail hole of the plate and pushes out and removes the nail driven into the nail hole, it is possible to always perform the nail pulling work properly.
