Description

The present invention relates to a driving machine that uses a power source such as compressed air to hit a stopper.
In particular, the present invention relates to a stopper feeding mechanism of a driving machine that hits a connected substantially U-shaped stopper and drives it into a driven material.

  The magazine in the tacker has a magazine that can hold a plurality of staples at right angles to the staple nose of the driver blade. A slidable feeder and a feeder are attached to the nose side of the passage in the magazine. A feeding mechanism comprising a coil spring that is energized is configured. The staple accommodated in the front of the feeder energizing side in the passage is pressed against the nose portion by the feeder. It is possible to launch up to staples.

  The width of the staple that can be loaded into the tacker is determined by the width of the guide groove inside the magazine and the width of the staple feeding mechanism. Conventionally, the guide groove width in the magazine and the rail width of the staple feeding mechanism are determined in accordance with one type of staple width, so the width of staples that can be loaded into one product is limited to one type. On the other hand, staples currently used in rechargeable tackers are mainly 10 mm and 12 mm wide. However, since the staple width that can be loaded into the tacker is limited to one type, it is necessary to select and use staples suitable for each tacker, which is inconvenient and inconvenient.

  An object of the present invention is to provide a tacker that solves the above-described drawbacks and can share two types of staples.

  The purpose of the present invention is to configure the distance between the outer side surfaces of the staple having a wide guide groove width inside the magazine, to configure the distance between the inner side surfaces of the staple having a narrow rail width of the staple guide, This can be achieved by configuring the staple pressing surface width so that both the wide staple and the narrow staple can be biased, and the striking width of the striking member so that both the wide staple and the narrow staple can be hit.

  According to the present invention, a tacker that can share two types of staples can be provided.

  FIG. 1 is an overall view of a rechargeable tacker according to an embodiment of the present invention, and FIG. 2 is a detailed view of a nose portion 1 and a magazine 3. A nose portion 1 and a magazine 3 connected to the nose portion 1 are attached to the lower part of the main body 8 of the rechargeable tacker. A battery 9 is connected to the rear end of the main body 8 to supply power to a motor (not shown). A motor (not shown) operates by operating the trigger 10. Elastic energy is accumulated in a coil spring (not shown) by the rotation of the motor, and the driver blade 2 can eject the staple 6 from the nose portion 1 by releasing the energy.

  As shown in FIG. 2, one end of the magazine 3 is connected to the nose portion 1, and the driver blade 2 is disposed in the nose portion 1 so as to be able to reciprocate.

  As shown in FIG. 3 to FIG. 6, the staple 6 as a stopper housed in the magazine 3 includes two driving needle portions extending in parallel and a connecting portion that connects the driving needle portions. As a whole, it is substantially U-shaped. A number of staples 6 are bonded together to form a series.

The magazine 3 is formed with a passage 3d in which the staple 6 can be stored. Side walls 3c are provided on the surfaces of the passage 3d facing the driving needle portion of the staple 6, respectively. The staple guide 4 is positioned between the driving needle portions of the staple 6 so as to support the connecting portion. The staple guide 4 is movable in the longitudinal direction of the magazine. The staple guide 4 is loaded in a state in which the staple guide 4 is slid in the direction opposite to the nose portion 1, and then the staple guide 4 is slid in the direction of the nose portion 1. Inserted. As a result, the staple 6 is loaded into the magazine 3 so as to straddle the staple guide 4.

  The staple guide 4 is provided with a feeder 5 that abuts against the staple 6 and moves linearly along the passage 3d, and a coil spring 7 that urges the feeder 5 forward. 1 can be pressed. At the time of staple driving, the head of the staple 6 pushed out to the nose portion 1 is driven out by the protrusion of the driver blade 2. Thereafter, when the driver blade 2 is pulled up, the leading edge of the staple 6 is pushed out to the nose portion 1 again by the urging force of the feeder 5, and preparation for the next launch is completed.

  The magazine 3 configured as described above has two types of staples having different connecting portions, that is, a first stopper 6a having a width of the first connecting portion (hereinafter referred to as “narrow staple 6a”). A second stopper 6b (hereinafter referred to as “wide staple 6b”) having a larger width of the second connecting portion than the first stopper 6a can be accommodated.

  That is, the distance between the side walls 3c of the magazine 3 described above is matched to the width of the connecting portion of the wide staple 6b (the width of the second connecting portion), and the driving needle portion of the wide staple 6b can be guided. . On the other hand, the distance between the wall surfaces of the staple guide 4 is adjusted to the width of the connecting portion of the narrow staple 6a (the width of the first connecting portion), and the driving needle portion of the narrow staple 6a can be guided.

  The feeder 5 is designed to have a shape capable of pressing both of the two types of staples, and the driver blade 2 has a structure capable of ejecting both the narrow staple 6a and the wide staple 6b.

  Here, the width of the connecting portion of the narrow staple 6a is 10 mm, and the width of the connecting portion of the wide staple 6b is 12 mm. And the width (contact width) of the surface which contacts the staple of the feeder 5 is 11 mm. These dimensions can be variously changed according to the size of the staple used.

  Further, an inclined surface 4b is formed at the front end portion of the staple guide 4 from the front end surface 4c to the side surface 4a to facilitate loading of the narrow staple 6a into the magazine 3 as will be described later. Further, a groove 3a for correcting the posture of the narrow staple 6a is formed on the surface of the staple 6 that faces the connecting portion.

  A method of loading the narrow staple 6a in the tacker constructed according to the present invention will be described.

When performing staple loading with the tacker, as shown in FIGS. 3B, 5A, and 6B, the main body is oriented so that the magazine opening 3f is directed upward, and the staples are stapled. The guide 4 is retracted in a direction away from the nose portion 1, the staple is disposed so that the top surface of the staple faces the magazine ceiling surface 3 e, and the staple guide 4 is advanced again in the direction close to the nose portion 1 to load the staple. Complete. At this time, the feeder 5 presses the loaded staple toward the nose portion 1.

As shown in FIG. 3, the magazine 3 is formed with posture correction grooves 3a for narrow staples 6a. An inclined surface 3b is formed in the attitude correction groove 3a from the side wall 3c of the magazine 3 to the magazine ceiling surface 3e. The width of the magazine ceiling surface 3e is substantially the same as the width (first width) of the connecting portion of the narrow staple 6a. Accordingly, as shown in FIG. 3B , when the narrow staple 6a is arranged in the magazine 3, the staple 6a falls into the posture correction groove 3a along the inclined surface 3b . Therefore, as shown in FIG. The rear end of 6a is moved to the vicinity of the center of the magazine 3 by the attitude correction groove 3a.

  Further, an inclined surface 4b is formed at the leading end portion of the staple guide 4 from the leading end surface 4c to the side surface 4a. For this reason, when the staple guide 4 is inserted, the leading end 4a easily enters between the driving needle portions of the narrow staple 6a and is further guided through the inclined surface 4b and the side surface 4a. Is completed smoothly. Further, since the staple guide side surface 4a serves as a rail that regulates the space between the inner side surfaces of the driving needle portion of the narrow staple 6a, the narrow staple 6a can be loaded at the center of the magazine 3. Similarly, when the staple is driven, since the inner side surface of the staple 6a is regulated by the staple guide side surface 4a, the staple 6a is fed toward the nose portion 1 while being positioned at the center of the magazine 3. The leading end of the staple 6a pushed out to the nose portion 1 is driven out by the protrusion of the wide driver blade 2. Thereafter, when the driver blade 2 is pulled up, the urging force of the feeder 5 pushes the top of the staple 6 again toward the center of the nose portion 1, and preparation for the next launch is completed.

Further, as shown in FIG. 5, during the loading operation of the narrow staple 6a, the ceiling surface 3e of the magazine 3 is narrowed as the staple guide 4 approaches the nose portion 1, so that the staple 6a is inclined in the vertical direction. And is pulled out of the posture correction groove 3a by the urging force of the feeder 5, and when the staple guide 4 is completely inserted, the staple 6a is loaded in parallel to the staple guide 4.

  On the other hand, as shown in FIG. 6, when the wide staple 6b is loaded, the staple side surface is regulated by the magazine side surface 3c when placed in the magazine 3, so that the posture correction groove 3a having a narrower width is formed. The staple 6b does not enter. Further, when the staple guide 4 is inserted, the staple 6b is urged by the feeder 5 and fed toward the nose portion 1 along the magazine side surface 3c, and the staple 6b is completely loaded. Similarly, when the staple is driven, the staple side surface is regulated by the magazine side surface 3c, so that the staple side is fed out in the direction of the nose portion 1 along the magazine side surface 3c.

  As described above, the embodiment of the present invention has been described using the rechargeable tacker. However, the present invention is not limited to this, and can be applied to those using compressed air as power.

  According to the present invention, it is possible to load a plurality of types of stoppers having different widths of the connecting portion into the magazine, and realize a configuration for correcting the position of the stopper. Thereby, it is possible to use a plurality of types of stoppers in one driving machine, and it is possible to stably feed the stoppers to the nose portion.
