に送り込む釘送り機構に関するものである。[Detailed description of the invention] The invention is based on a pneumatic nailing machine, for example.
The connected nails fed into the nail driving nose by the nail feeding claw are hit one by one, starting from the most distal end, by a driver member that rapidly lowers the nails inside the nose. Regarding a nailer capable of driving nails by driving the nails out from the tip of the nail, the nailer is of a type in which a part of the nail feeding claw enters the nose, and in particular, the nailer is capable of driving nails by driving the nails out from the tip of the nail. This relates to a mechanism for feeding nails into the nose in order from the most distal end.

がら上記釘供給口に向つて進入・後退駆動する釘
送り爪によつて、一本ずつ上記ノーズ内に送り込
むように構成されている。 Conventionally, in this type of nailing machine, a nail supply port is provided at one side of a nailing nose protruding from the nailing machine body. The connected nails, which are made by connecting a large number of nails in parallel at regular intervals, are driven by a nail feeding claw that enters and retreats toward the nail supply port while timing the movement of the driver member that reciprocates inside the nose. Therefore, it is configured to be fed into the nose one by one.

記釘供給口から後退する方向にスイングしてしま
うことになる。 By the way, when the nail fed into the nose by the nail feeding pawl is hit by the driver member, the nail that was hit will be damaged by the second adjacent nail (the next nail to be driven). ) Due to the strong supporting force of the connecting material that connects the nail foot, the tip of the nail foot is drawn toward the nail feeding claw, causing the nail feeding claw to swing in the direction of retreating from the nail supply port. It turns out.

拾い込み部を該釘供給口の下端側に設けたもので
あつても、釘は上記釘送り爪を押い退けるように

た。 In this way, if the nail feeding pawl swings, even if a nail foot pick-up part is provided at the lower end of the nail supply port to prevent the nail from flying out of the nail supply port, the nail will not fly out of the nail supply port. As the nail feed claw is pushed away, the nail may fly out of the nail supply port, and safety is not necessarily maintained.

対しては好ましいものではない。 To this end, there have been conventionally provided devices in which a ratchet pawl, which functions to prevent the nail from flying out, is disposed near the nail foot pick-up portion. However, the provision of the ratchet pawl increases the number of parts, which is not preferable for small-sized nailers in which weight reduction is desired.
そこで、本考案は上記従来の欠点を解消するた

とするものである。 To this end, the nail feeding mechanism of the present invention has a connecting nail, which is made by connecting multiple nails in parallel at regular intervals using a connecting material, on one side of the nail driving nose that protrudes from the nailer body. The nails are fed into the nose one by one by the nail feeding claw, which is driven forward and backward toward the nail feeding port where the nails are fed into the nose, and a portion of the nails enter the nose. In order to prevent the nail from jumping out of the nail supply path when the nail is hit by the reciprocating driver member, a nail foot pick-up section provided at the lower end of the nail supply port is used to prevent the nail from jumping out of the nail supply path when the nail is hit by the reciprocating driver member. In the nail driving machine, the tip of the nail feed nail can abut on the back side of the feed nail between the nail supply port position of the nose and the inner end position of the nose. A portion is formed in the nose to prevent at least the tip of the nail feeding pawl from being retracted from above the nail path including the nail supply port within the aforementioned range.

沿つて移動させられる。 As shown in FIG. 3, the connecting nail 1 is pulled out from the magazine 7 into the nail feeding passage 23.
00 indicates that the passage 2 is opened by the feed mechanism 10.
The nails are fed into the nose 5 one by one by the nail feeding claw 15 which advances and retreats inside the nail supply port 24. In addition, the above-mentioned connecting nail 100
The nails a 1 , a 2 , ... are connected by connecting members 6 , 6 so that the nail heads C overlap in a stepped manner, and each nail a 1 , a 2 , .
Since the pitch between a 2 has become smaller and the diameter of the nail head C is larger, the nail feed claw 15
The operation is such that the leading edge of the nail a1 is pushed directly into the nose 5. Further, during the nail feeding operation, the nail head C of each nail a 2 , a 3 , . . . in the nail feeding passage 23 moves along the nail head guide groove 31 formed in the nail guide plate 8. I am made to do so.

釘ガイド壁を構成した状態となる。 Then, the nail feeding claw 15 that has sent the most advanced nail a1 into the nose 5 is moved so that the tip end 4a of the driver member 4 reaches the nail head C of the nail a1 by the pulling operation of the trigger 9. At the same time as the collision occurs, the feed mechanism 10 moves backward as shown in FIG. 4 and temporarily stops at the nail supply port 24. At this time,
Rear slope 15A of the tip 15a of the nail feeding claw 15
does not touch the second nail (the next nail to be driven) a2 , and a predetermined clearance is maintained between the slope 15A and the second nail a2 . The tip end edge 15B of the nail feeding pawl 15 is connected to the support pin 16 as a fulcrum by a protruding wall 32 for resting the nail feeding pawl, which is formed on one side wall 24A of the inner circumference of the nail supply port 24. The clockwise rotation in FIG. 4 is prevented. By blocking the rotation of the nail feeding claw 15, the front end surface 15C of the tip 15a of the nail feeding claw 15 is
This creates a nail guide wall that prevents the nail a1 from flying out within the nail supply port 24.

The connecting member 6 connecting the two sides could not be torn off, and the nail a1 was tilted as shown by the arrow in FIG. Even if a pressing force is applied to rotate the nail feed claw 15 in this direction, the nail feed claw 15 is prevented from rotating. Therefore, the inclined nail a1 does not fly out from the nail supply port 24, but instead reaches the front end surface 1 of the nail feeding claw 15.
While being guided by 5C, its posture is corrected and it can be driven perpendicularly into the material to be driven (not shown).

の後退は停止する。 Then, when the nail foot tip b 1 of the nail a 1 passes the position of the nail foot pick-up portion 25, the nail feeding claw 15 recedes linearly from the position of the nail supply port 24. Due to this retreat, the rear inclined surface 1 of the nail feeding claw 15
5A is in contact with the second nail a 2 , and the above nail feeding claw 1
5 further retreats while swinging around the support pin 16 as shown by the arrow in FIG.
As shown in the figure, when the tip 15a of the nail feeding claw 15 enters between the second nail a2 and the third nail a3 , its retreat stops.
