【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows the overall structure of a nail driver. This nailing machine is roughly composed of a nailing machine body A that operates a hammer, a nailing device B and a nail feeding device C. The nails 10 housed in the nail feeding device C are delivered one by one to the nailing device B in response to the hammer of the impact part A1 of the nailing machine body A, and ejected from the nailing passage B1 to the outside. . The present invention relates to the improvement of the nail feeding mechanism in such a nailing machine, and the nailing machine main body A is not different from the conventional one, so its explanation is omitted here.

1 to 4, the nail feeding device C is provided with a single rod-shaped main body 30, and the main body 30 is provided with a hole 32 and a recess 33 extending parallel to the longitudinal direction thereof. There is. The body 30 is also provided with a slit 34 which connects the hole 32 and the recess 33 to each other in the longitudinal direction. A pair of grooves 31 is formed on both edges of the recess 33 of the main body 30, and one nail support plate 40 is attached to and detached from the main body 30 by fitting flanges 41 on both sides of the nail support plate 40 into the grooves 31. It is installed freely.

Reference numeral 50 denotes a shaft slidably inserted in the hole 32 of the main body 30, and a plurality of long grooves 51a, 51b, 51c extending in the axial direction and having different depths are formed on the peripheral portion of the shaft 50. Are provided in a radial pattern. Each long groove extends through one end 52 of the shaft 50 engaged with the nailing device B. The other end portion 53 of the shaft 50 extends to the outside of the main body 30, and the other end portion 53 is engraved with serrations for facilitating the rotation of the shaft 50. A peripheral groove 54 is also provided in the other end portion 53 of the shaft 50, and a stopper plate 55 fixed to the end surface of the main body 30 with a bolt 56 is fitted in the peripheral groove 54. That is, the shaft 50 is prevented from coming out of the hole 32 of the main body 30 by the stopper plate 55, and is allowed to rotate only.

Reference numeral 60 denotes a nail pushing member housed in the recess 33 covered with the nail support plate 40, which has been conventionally used in general. The nail pushing member 60 has a nail pushing piece 61 that fits in the slit 34 at the tip thereof, and has one end fitted into a hole 71 of a second face plate 70 of the nailing device B described later to form a concave portion. It is possible to move back and forth along a pair of guide rods 62 extending inside 33. A spring 63 is wound around each guide rod 62, and the nail pushing member 60 pushes the nail 10 into the nailing device B by being urged forward (nail pushing direction) by the spring 63. . The lower end of the nail 10 is seated on the nail support plate 40, and the upper end of the nail 10 is inserted through the slit 34 to be inserted into one of the long grooves 51a, 51b, 51c of the shaft 50. Many will be packed into. Therefore, in order to replenish or replace the nail 10, the nail support plate 40 may be slid and retracted and the nail pushing member 60 may be retracted to pack the nails.

Therefore, in order to align one of the long grooves of the shaft 50 with the slit 34, positioning means is provided between the main body 30 and the shaft 50. As shown in FIG. 3, this positioning means includes a screw member 38 screwed into a screw hole 35 provided in the main body 30 toward the axis of the hole 32, and a shaft hole 381 of the screw member 38. The ball 36, which is movably held, the spring 37 which is housed in the shaft hole 381 and urges the ball 36 in the direction of coming out of the hole 32, and the mouth of the long grooves 51a, 51b, 51c of the shaft 50, are provided so as to coincide with each other. And a recessed portion 511 formed therein. By manually grasping the end portion 53 of the shaft 50 and turning the shaft 50 appropriately, the ball 36 is fitted into the recessed portion 511 and the rotation of the shaft 50 is restricted. At this time, one of the long grooves 51a, 51b and 51c is locked. The slits 34 are positioned so that they are aligned with each other.

On the other hand, in the nailing device B, the first face plate 80 having the nailing groove 81 and the second face plate 70 are integrally combined, and in this combined state, the nailing groove 81 is the second surface plate. Is closed by the face plate 70 to provide the nailing passage B1. The second face plate 70 has a circular hole 73 into which the one end portion 53 of the shaft 50 is fitted, and a vertical groove 72 extending from the circular hole 73 along the nailing passage B1. The slit 34 in the main body 30 of the nail feeding device C is arranged so as to be aligned with the vertical groove 72, and the nail 10 in the nail feeding device C is provided with a part of the circular hole 73 of the second face plate 70 and the vertical groove. With 72 as the final passage, it is sent out into the nailing passage B1.

In the nailing machine configured as described above, one of the recess 33 of the main body 30 covered with the nail support plate 40, the slit 34 in the main body 30 and the long grooves 51a, 51b, 51c, ... If a plurality of nails 10 are packed in front of the nail pushing member 60 by forming the feeding passage and aligning one of the long grooves with the slit 34 in advance, the hammer of the impact portion A1 of the nailing machine main body A can be obtained. The nails 10 are sent to the nailing device B one by one in accordance with the above, and are ejected from the nailing passage B1 to the outside.

When the length of the nail 10 is changed, first, the nail support plate 40 is opened to take out the nail in the recess 33, and then the end 53 of the shaft 50 is gripped to rotate the shaft 50. Add. Then, the ball 36 of the positioning means moves backward against the biasing force of the spring 37 and rides on the peripheral surface of the shaft 50, so that the shaft 50 rotates smoothly. Then, when the shaft 50 is appropriately rotated, the ball 36 is fitted into the next recessed portion 511, and the other one of the long grooves 51a, 51b, 51c ... Is positioned with respect to the slit 34. That is, if the height of the nail feed passage is changed and the height of the nail feed passage corresponds to the desired nail length, the nail to be driven next is packed in the main body 30 and the nail is again pushed. The support plate 40 is closed. At this time, if the height of the nail feeding passage does not correspond to the desired nail length, the shaft 50 is further rotated to align the long groove of the desired depth with the slit 34, and the nails are packed as described above. In this way, the height of the nail feed passage can be changed simply by rotating the rotary shaft 50, and the setup can be changed very quickly.

In the above embodiment, the shaft 50 is provided with a plurality of long grooves 51a, 51b, 51c ... Having different depths, and the height of the nail feeding passage is changed by selecting the long grooves. If the nail 10 is a wide one, the shaft 50 may be provided with a flat surface 55 including a line parallel to the tangent to the circumference of the shaft 50, as shown in FIG. 5, in place of the long groove. In this case, one of the recess 33 of the main body 30 covered by the nail support plate 40, the slit 36 in the main body 30 and the flat surface 50 forms a nail feed passage, and the plane 50 is selected as in the above embodiment. This makes it possible to change the height of the nail feed passage.

[0018]
