給送装置に関するものである。[Detailed description of the invention] [Field of application of the invention] The present invention is applicable to driving machines such as air nailers or electric nailers that continuously drive a large number of connecting fasteners connected by connecting pieces. The present invention relates to a fastener feeding device that feeds fasteners to an injection port.
以下打込機を空気式打込機として説明する。 The driving machine will be explained below as a pneumatic driving machine.

成される。 FIG. 2 shows a pneumatic driving machine of a known construction. As is well known, the pneumatic driving machine includes a main body 1 that stores compressed air from an air compressor (not shown) and serves as a handle, a cylinder (not shown), and a cylinder (not shown) that is integrally provided in front of the main body 1. A driving unit 4 consisting of a piston 5 etc. that reciprocates in the vertical direction, a magazine 7 that accommodates a large number of fasteners 9 attached to the lower part of the main body 1 and connected by connecting pieces 10 made of, for example, a plastic band; It is composed of an injection port 6 provided below the drive section 4, a feeding section 8 for feeding the stopper 9 from the magazine 7 into the injection port 6, and the like.

When opened and compressed air is supplied to the drive unit 4,
The piston 5 descends impulsively and hits the stop 9 in the injection port 6. The stopper 9 is separated from the connecting piece 10 and driven into a material to be driven (not shown). After the stopper 9 has been driven in, the remaining connecting piece 11 is sequentially discharged through an opening 12 provided in the side wall of the injection port 6, as shown in FIG.

への戻りすなわち逆送りを阻止するものである。 As described above, the feeding section 8 feeds the connecting stops 9 sent out from the magazine 7 into the injection port 6 one by one, and as shown in FIGS. A feed piston 17 constituting the moving member of the present invention that reciprocates along the stop feed direction, and a spring 2 that pushes the piston 17 toward the injection port 6 side.
0. A feed pawl 13 mounted on the tip of the piston 17 via a pin 16 so as to be rotatable about the pin 16, a feed pawl spring 14 that presses the feed pawl 13 toward the stop feed passage, and a locking mechanism. It is composed of claws 15 and the like. Compressed air is supplied to the passage 19 of the cylinder 18 in response to the movement of the piston 5, and at this time the piston 17 retreats, and when the supply of compressed air stops, the piston 17 is pushed forward by the spring 20. The feed pawl 13 has a protrusion 13a extending to the stop feed passage, and the protrusion 13a sends the connecting stop 9 by pushing the second stop 9 from the injection port 6 side. The connecting stop 9 comes into contact with the leading stop 9 from the injection port 6 side and prevents the connecting stop 9 from returning to the magazine 7 side, that is, from being reversely fed.

止具９の後退を阻止している。 FIG. 4 shows the state of the feeding section 8 immediately after the stopper 9 in the injection port 6 is driven. The feed piston 17
The pressure of the compressed air flowing in from the passage 19 overcomes the spring 20 and retreats to the right in the figure, that is, toward the magazine 7 side. At this time, the protrusion 13a of the feed pawl 13 rotates toward the anti-stop feed path side and moves backward from the injection port 6 over the second stop 9b, while the locking pawl 15 moves from the injection port 6 to the first stop. The stopper 9a is locked to prevent the connecting stopper 9 from retreating as the feed pawl 13 retreats.

まりを生じるという欠点があつた。 However, in this prior art, although the connecting stopper 9 is prevented from being sent back to the magazine 7 by the locking pawl 15, it is free to move toward the injection port 6, for example as shown in FIG. , the remaining connecting piece 11
When the connecting stopper 9 is pulled to the left in the figure, the connecting stopper 9 moves until the leading stopper 9a contacts the piston 5. This has the disadvantage that the normal feeding process of the connecting stopper 9 is hindered, and as a result, the stopper 9 becomes clogged within the injection port 6.

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art, to prevent the connecting stopper from moving toward the injection port except during feeding, and to provide a feeding device that does not cause abnormalities such as clogging of the stopper. It is to provide.

In the present invention, the movement of the connecting stopper toward the injection port side other than during feeding as described above is caused by the fact that the distance between the feed claw protrusion and the stopper is large, and the feed claw protrusion rotates toward the side opposite to the stopper feeding path. Taking into consideration the fact that this occurs, the shape of the feed pawl protrusion and the abutting portion that prevents the feed pawl from rotating toward the anti-stop feed path side have been devised.

FIG. 1 shows an embodiment of the main part of the stop feed device of the present invention. A rear protrusion 13b is provided which has a length slightly shorter than the pitch of the connecting stop 9 and extends in a direction opposite to the stop feed passage side of the feed pawl 13, and further faces the rear protrusion 13b. It is characterized in that a projection 18a is provided on a part of the cylinder 18.
この結果、連結片残部１１を図中左方に引いた
としても、連結止具９が直ちに送り爪突起１３ａ

る。 As a result, even if the remaining portion 11 of the connecting piece is pulled to the left in the figure, the connecting stop 9 immediately moves to the feed claw protrusion 13a.
At the same time, the feed claw 13 touches the rear projection 13b.
Since the cylinder protrusion 18a prevents the coupling stopper 9 from rotating toward the side opposite to the stopper feeding passage, the connecting stopper 9 will not move toward the injection port 6 side. Therefore, it is possible to reliably prevent the above-mentioned abnormal driving.

As described above, according to the present invention, it is possible to reliably prevent the connecting stopper from moving toward the injection port at times other than during feeding, and it is possible to eliminate abnormal driving such as clogging of the stopper.
