[4. Drive mechanism]
The drive mechanism 32 that drives the driving mechanism 20 configured as described above moves the plunger 25 from the first fixed member 21 side to the second fixed member 22 side against the elastic force of the plunger spring 26. . As shown in FIGS. 3, 4A, and 4B, the drive mechanism 32 includes a drive motor 33 that serves as a drive source. A worm 34 is attached to the spindle of the drive motor 33, and the worm 34 is engaged with a planetary gear mechanism 35 that serves as a speed reduction mechanism and is excellent in torque transmission. Furthermore, an arm gear 36 is engaged with the planetary gear mechanism 35. Further, the arm gear 36 is engaged with a first torque gear 37 that moves the plunger 25 against the elastic force of the plunger spring 26, and the first torque gear 37 is engaged with a second torque gear 38. Yes. The arm gear 36, the first torque gear 37, and the second torque gear 38 are supported by a single gear plate 39. That is, the gear plate 39 includes the arm gear 36 in addition to the shaft-shaped first support portion 39 a that supports the first torque gear 37 and the shaft-shaped second support portion 39 b that supports the second torque gear 38. A cylindrical third support portion 39c that pivotally supports the shaft. The arm gear 36, the first torque gear 37, and the second torque gear 38 are attached to a single gear plate 39, so that variations in the distance between the centers of the gears can be suppressed, and the durability of the gear teeth can be improved. Furthermore, driving loss is reduced.

  The first torque gear 37 is provided with a first torque roller 41 serving as a first drive protrusion that engages with the first engagement protrusion 29 of the plunger 25, and the second torque gear 38 includes a plunger 25. A second torque roller 42 serving as a second drive protrusion that engages with the second engagement protrusion 30 is provided. The first torque gear 37 and the second torque gear 38 meshing with each other rotate the first torque gear 37 in the direction of arrow R1 in FIG. 5 and the second torque gear 38 in the direction of arrow R2 in FIG. Thereby, the 1st and 2nd torque rollers 41 and 42 follow the locus shown in Drawing 5 (A)-(D).

  As shown in FIG. 5 (A), the first engagement protrusion 29 of the plunger 25 moves when the plunger 25 is at the bottom dead center position when the first torque roller 41 of the first torque gear 37 moves. Above, when the first torque roller 41 starts moving in the circumferential direction from the lowest initial position and starts to rise, the first torque roller 41 is in a position to engage with the first torque roller 41. Further, as shown in FIG. 5 (B), the second engagement protrusion 30 immediately before the plunger 25 moves upward and the first torque roller 41 of the first torque gear 37 reaches the uppermost portion.

The plungers 25 are sequentially engaged, and the plunger 25 is lifted from the first fixing member 21 side to the second fixing member 22 side against the elastic force of the plunger spring 26.

  In such a drive mechanism 32, when the drive motor 33 is started, the first torque gear 37 and the second torque gear 38 are opposite to each other (arrows R1, R2 in FIG. 5) via the planetary gear mechanism 35 and the arm gear 36. Direction). When the plunger 25 is at the bottom dead center position, as shown in FIG. 5A, the first torque roller 41 of the rotating first torque gear 37 is the lower surface of the first engagement protrusion 29 of the plunger 25. Engage with. As the first torque gear 37 continues to rotate in the direction of the arrow R <b> 1, the first torque roller 41 rises and the plunger 25 is lifted against the plunger spring 26. Then, as shown in FIG. 5B, immediately before the first torque roller 41 reaches the top, the second torque roller 42 of the second torque gear 38 starts to rise in the direction of the arrow R2 from the bottom. The plunger 25 engages with the lower surface of the second engagement protrusion 30 of the plunger 25. As the second torque gear 38 continues to rotate in the direction of the arrow R2, the plunger 25 is further lifted to the position shown in FIG. As shown in FIG. 5D, when the second torque gear 38 is further rotated and the second torque roller 42 is disengaged from the second engaging protrusion 30, the plunger 25 is moved by the elastic force of the plunger spring 26. The second fixing member 22 is driven in the direction of the first fixing member 21. At this time, the driver 27 coupled to the plunger 25 moves in the direction of the arrow D1 in FIGS. 2 and 6, drives the fastener supplied to the injection port 11b, drives it toward an external object, and drives the fastener. The one cycle ends.

  In addition, although the number of torque gears demonstrated two examples here, it is determined according to the movement distance of the plunger 25, and is not limited to two especially, Even if it is one It may be three or more. According to the number of torque gears, that is, according to the number of torque rollers provided in the torque gear, the plunger 25 is provided with an engaging protrusion. The drive mechanism 32 that drives the driving mechanism 20 resists the elastic force of the plunger spring 26 by winding up the plunger 25 that is biased in the driving direction by the plunger spring 26 with a winch that pulls the plunger 25. It may be a drive mechanism that is moved.

[5. Buffer mechanism]
As shown in FIG. 6, the pipe 24 of the driving mechanism 20 is provided with a buffer mechanism 43 for buffering an impact when the fastener is driven. The buffer mechanism 43 includes a weight 44 disposed in the pipe 24, a weight spring 45 that urges the weight 44 in the direction of the second fixing member 22 (the direction of arrow D2 in FIG. 6), and a second fixing member. 22, a weight stop 46 disposed inside the pipe 22, a wire 47 connecting the weight 44 inside the pipe 24 and the plunger 25 outside the pipe 24, and a pulley 48 that guides the wire 47. Yes.

  The weight 44 has a large diameter portion 44 a and a small diameter portion 44 b, and the large diameter portion 44 a slides on the inner surface of the pipe 24, thereby moving the pipe 24 linearly. One end of the wire 47 is engaged with the protrusion 47a of the weight 44. The other end of the wire 47 is engaged with the protrusion 47 b of the plunger 25. The weight spring 45 is, for example, a compression coil spring disposed in the pipe 24 between the first fixing member 21 and the weight 44, and the weight 44 is moved in the direction of the second fixing member 22 (arrow D2 in FIG. 6). Direction). One end of the weight spring 45 is engaged with the large diameter portion 44 a of the weight 44.

  As shown in FIG. 7, when the plunger 25 is at the bottom dead center position, the weight 44 is in contact with the weight stop 46 on the second fixing member 22 side by the elastic force of the weight spring 45. Next, as shown in FIG. 8, when the plunger 25 is lifted to the top dead center position by the drive mechanism 32, the weight 44 is pulled by the plunger 25 via the wire 47, so that the elastic force of the weight spring 45 is reduced. Accordingly, the weight spring 45 is contracted and moved in the direction of the first fixing member 21 (counter arrow D2 direction (arrow D1 direction)).

  When driving the fastener, as shown in FIGS. 9 and 10, the plunger 25 is vigorously moved in the direction of the first fixing member 21 (in the direction of arrow D <b> 1) by the elastic force of the plunger spring 26. At this time, the driving tool 1 generates a reaction force P1 that is pushed up from the object. At this time, the wire 47 is temporarily slackened by the plunger 25 moving vigorously in the direction of the second fixing member 22 (arrow D1 direction) by the elastic force of the plunger spring 26, and the weight 44 is independent. The inside of the pipe 24 is moved in the direction of the second fixing member 22 (arrow D2 direction) by the elastic force of the plunger spring 26. This sets the weight of the plunger 25, the load of the plunger spring 26, the weight of the weight 44, and the load of the weight spring 45 so that the speed of the plunger 25 by the plunger spring 26 is faster than the speed of the weight 44 by the weight spring 45. This can be achieved. As a result, the driving tool 1 generates a pressing force that presses the weight 44 in the direction of the object by the reaction force P2 of the weight spring 45 that tries to push up the weight 44 in the direction of the second fixing member 22.

  Thus, in the buffer mechanism 43, the reaction force P1 pushed up from the object can be weakened or canceled by the reaction force P2 of the weight spring 45. In addition, the buffer mechanism 43 includes (the load P2 of the weight spring 45 + the load of the driving tool 1 (pressing load by the operator ± tool weight) P3) and (the reaction force P1 when the fastener is driven + the load of the plunger spring 26 (reaction) The force) P4) and the forces cancel each other, whereby the total reaction amount of the driving tool 1 can be determined. As described above, the driving tool 1 can appropriately set the load applied to the object when the fastener is driven. For example, when the fastener is driven into the interior finish, the pressing tool is pressed toward the target. It is possible to prevent the pressure from becoming too strong and scratching the surface.

  As shown in FIG. 12C, in the storage portion 54 of the magazine 50 in which the take-out groove 57 is not provided, particularly when the plate-like connecting band 51 is stored in a substantially full state, it is pulled out from the guide member 56. It is necessary to slide the body body 10a toward the auxiliary grip portion 13 side. At this time, a gap 58 is required between the magazine 50 and the auxiliary grip portion 13 so as to be hooked on the plate-like connecting band 51 from which a finger is pulled out. On the other hand, as shown in FIGS. 11C and 12B, the magazine 50 of the driving tool 1 is provided with an extraction groove 57. Therefore, as shown in FIG. 11C, in the magazine 50, the plate-like connecting band 51 is slid toward the auxiliary grip portion 13 of the body main body 10a. Then, in the magazine 50, the plate-like connecting band 51 can be raised by pressing the plate-like connecting band 51 against the take-out groove 57, and the plate-like connecting band 51 can be taken out. Accordingly, in the driving tool 1, the gap 58 between the magazine 50 and the auxiliary grip portion 13 can be reduced, and the overall size can be reduced.

  As shown in FIGS. 13A and 13B, the magazine 50 does not necessarily need to be provided with the guide member 56 as long as the take-out groove 57 is provided. In the example of FIG. 13, an extraction groove 57 is provided at a position where the guide member 56 of the magazine main body 52 is provided. That is, the take-out groove 57 is formed to be continuous with the side wall 59 with the side wall 59 of the magazine 50 as a positioning wall. In this case, a guide piece 59a instead of the second guide piece 56b may be provided at the tip of the side wall.

  In the example of FIG. 12, the take-out groove 57 is further provided so that the tip of the second guide piece 56b and the end 57b opposite to the end 57a partially overlap in plan view. Good. Also by this, the plate-like connecting band 51 can be pushed up and pushed up into the take-out groove 57 before the one end portion is completely removed from the guide member 56, and the magazine 50 and the auxiliary grip portion 13 can be further raised. The gap 58 can be narrowed.

  Furthermore, the shape of the magazine 50 may be provided so as to be bent forward or backward rather than substantially perpendicular to the axial direction of the body 10 or to be inclined.

[7. Overall operation and effects]
Operation | movement of the driving tool 1 comprised as mentioned above is demonstrated. First, when the fastener is driven into an object such as wood, gypsum board, steel plate, or concrete, the contact arm 11a of the nose portion 11 is pressed against the object as shown in FIG. Next, the trigger 15 is pulled, and when this is detected by a microswitch or the like, the drive motor 33 of the drive mechanism 32 is driven.

  Then, as shown in FIG. 5A, the first torque roller 41 of the rotating first torque gear 37 is engaged with the lower surface of the first engagement protrusion 29 of the plunger 25, and the plunger 25 is moved to the plunger. It is lifted against the spring 26 in the direction of the opposite arrow D1. Then, as shown in FIG. 5B, immediately before the first torque roller 41 reaches the uppermost position, the second torque roller 42 of the second torque gear 38 has the second engagement protrusion of the plunger 25. The plunger 25 is engaged with the lower surface of the portion 30, and the plunger 25 is lifted in the counter arrow D1 direction against the plunger spring 26 and moved to the position shown in FIG. Next, as shown in FIG. 5D, when the second torque gear 38 further rotates and the second torque roller 42 is disengaged from the second engagement protrusion 30, the plunger 25 has the elastic force of the plunger spring 26. As a result, the second fixing member 22 moves vigorously in the direction of the first fixing member 21. At this time, the driver 27 coupled to the plunger 25 moves in the direction of the arrow D1 in FIGS. 2 and 6, drives the fastener supplied to the injection port 11b toward the external object, and performs the fastener driving operation. One cycle ends.

  As described above, when the fastener is driven, the plunger 25 moves vigorously in the direction of the first fixing member 21 (the direction of the arrow D1) by the elastic force of the plunger spring 26 as shown in FIGS. . At this time, the driving tool 1 generates a reaction force P1 that is pushed up from the object. At this time, the wire 47 is temporarily slackened by the plunger 25 moving vigorously in the direction of the second fixing member 22 (arrow D1 direction) by the elastic force of the plunger spring 26, and the weight 44 is independent. The inside of the pipe 24 is moved in the direction of the second fixing member 22 (arrow D2 direction) by the elastic force of the plunger spring 26. As a result, the driving tool 1 generates a pressing force that presses the weight 44 in the direction of the object by the reaction force P2 of the weight spring 45 that tries to push up the weight 44 in the direction of the second fixing member 22. Thereby, the driving tool 1 can weaken or cancel the reaction force P1 pushed up from the object by the reaction force P2 of the weight spring 45.

  By the way, in the driving tool 1, when the fastener from the magazine 50, that is, when the plate-like connecting band 51 is replenished or removed, the slider 53 becomes the front end side of the magazine 50 as shown in FIGS. 11 and 12. By sliding in the direction of the arrow D3, the storage portion 54 is exposed to the outside, and the plate-like connecting band 51 can be taken in and out. As shown in FIGS. 11 (A), 11 (B), and 12 (A), the plate-like connection band 51 has a body main body 10a with one end portion where the tips of the fasteners of the plate-like connection band 51 are arranged as an insertion end. Is inserted into the guide portion 55 in the direction of the arrow D4 from the auxiliary grip portion 13 side, and is inserted between the first and second guide pieces 56a and 56b so as to lie on the support surface 54a, and abuts against the positioning piece 56c. It is done. Thereafter, the magazine 50 is slid in the direction of the opposite arrow D3 on the base side, whereby the storage portion 54 is closed and the driving tool 1 can be used.

  On the other hand, when the plate-like connection band 51 stored in the storage part 54 is taken out, as shown in FIG. 11B, first, the plate-like connection band 51 becomes the auxiliary grip part 13 side of the body main body 10a. Slide in the direction of the opposite arrow D4. Then, when one end of the plate-like connecting band 51 where the tip ends of the fasteners line up reaches the take-out groove 57, as shown in FIG. By being pressed, it rises along the inclined surface of the end portion 57a on the auxiliary grip portion 13 side of the take-out groove 57 and can be easily taken out by being gripped by the user. As shown in FIG. 12 (B), in the magazine 50 of the driving tool 1, an extraction groove 57 is provided, and before the plate-like connecting band 51 is pulled out from the guide member 56, the plate-like connecting band 51. It is possible to stand up by pressing the take-out groove 57, and the gap 58 between the magazine 50 and the auxiliary grip portion 13 can be reduced, and the overall size can be reduced.
