Description

  The present invention relates to a driving tool that uses a connecting nail connected in a plate shape.

  Some so-called pin nailers and finish nailers that use nails with a thin wire diameter include a guide mechanism for pressing down the nails in order to stabilize the nail feed in the magazine portion that houses the connecting nails. For example, in the configuration described in Patent Document 1, a plurality of elongated plate-like nail guides are attached along the nail feed direction. The nail guide is biased in the protruding direction by a spring, and presses the nail against the magazine body. Since the nail is pressed between the nail guide and the magazine main body by pressing the nail against the magazine main body by the nail guide in this way, the width of the nail is defined by the interval between the nail guide and the magazine main body.

Japanese Patent No. 3321936

  However, in the conventional configuration as described above, the nail guide is moved by the impact at the time of driving, and the width of the nail may be increased. Further, when the spring force is insufficient, the nail cannot be sufficiently pressed against the magazine body, and the width of the nail may increase.

  If the width of the nail is widened in this way, the nail will tilt with respect to the feed direction, and the pusher that pushes the nail from behind will ride on the nail, or the replenished connecting nail will ride on the existing nail there is a possibility. Thus, when the nail or the pusher is in a state of riding, there is a problem that the nail feeding operation cannot be normally performed.

  Therefore, an object of the present invention is to provide a driving tool that can stabilize the feeding operation without expanding the width of the nail even when an impact or the like at the time of driving is applied.

It is extended. According to such a configuration, the width of the nail is determined by the two members of the magazine main body (first support portion) and the cover body (second support portion). The width does not increase. Therefore, there is no problem that the pusher that pushes the nail from behind by tilting the nail rides on the nail or that the replenished connecting nail rides on the existing nail, so the feeding operation can be performed stably. .

  Further, since the width of the nail is determined by only two members, that is, the magazine main body and the cover body, it is easy to manage the dimensions of the parts. Therefore, since a nail with a thin wire diameter is used, a problem is hardly caused even if the tool is severely dimensioned.

  Embodiments of the present invention will be described with reference to the drawings.

  The driving tool 10 according to the present embodiment uses a connecting nail 30 connected in a plate shape as shown in FIG. 7 (c), and as shown in FIG. 1, a tool having a hammering mechanism therein. A main body 11, a grip 12 disposed behind the tool main body 11, a trigger 14 operably provided on the grip 12, a nose portion 15 provided so as to protrude from the tip of the tool main body 11, and a tool main body 11 and a magazine portion 20 connected in the vicinity of the tip.

  When the driving tool 10 is used, the grip 12 is grasped and gripped, and the trigger 14 is pulled. By this operation, the striking mechanism is activated, and the nail is driven out from the injection port 15 a formed at the tip of the nose portion 15. The nose portion 15 includes a driver guide 16 having an injection path formed therein. The driver 13 for driving the nail can reciprocate in the injection path. When the impact mechanism generates an impact force, the driver 13 moves in the nail driving direction and is set in the injection path. It is designed to shoot nails.

  As an example of the driving tool 10, here, a spring-driven nail driver driven by a spring force will be described. As shown in FIG. 8A, the driving tool 10 includes a plunger unit 42 in which a driver 13 is connected to the inside of a tool body 11, a drive mechanism 41 for operating the plunger unit 42, and a drive mechanism 41. And a micro switch 50 as detection means provided for detecting the operating state of the plunger unit 42.

  The plunger unit 42 includes a plunger 43 disposed so as to be slidable in the driving direction, and a plunger urging member 45 that constantly urges the plunger 43 toward the injection port 15a. A driver connecting portion 43 a for fixing the driver 13 is provided in front of the plunger 43. By connecting the driver 13 to the driver connecting portion 43a, the driver 13 is also slid in accordance with the sliding of the plunger 43. An engagement member 44 that engages with the drive mechanism 41 is provided behind the plunger 43.

  The drive mechanism 41 is for pushing up the plunger 43 against the urging force of the plunger urging member 45 and includes a plurality of gears. The plurality of gears are rotated by the driving force of the motor 40.

  The drive mechanism 41 rotates the gear while the plunger 43 is engaged with the gear, thereby pushing up the plunger 43. Then, after the plunger 43 moves to the top dead center, the engagement between the gear and the plunger 43 is released. When the gear is disengaged from the plunger 43, the plunger 43 is moved in the launch direction by the biasing force of the plunger biasing member 45, and the driver 13 connected to the plunger 43 slides in the direction of the injection port 15a. The nail is driven out.

  The motor 40 that drives the drive mechanism 41 is activated when the trigger 14 is operated, and operates until the micro switch 50 detects that the plunger 43 has moved to a predetermined position.

  Specifically, when the trigger 14 is operated from the standby state shown in FIG. 8A and the motor 40 rotates, the drive mechanism 41 operates to gradually lift the engagement member 44 (plunger 43) upward. When the plunger 43 moves to the top dead center position, the engaging member 44 presses the micro switch 50 as shown in FIG. Immediately thereafter, the drive mechanism 41 and the engagement member 44 are disengaged, and the plunger 43 and the driver 13 are moved toward the injection port 15a by the biasing force accumulated in the plunger biasing member 45 (see FIG. 11). When the plunger 43 moves to the bottom dead center position, the nail driving is completed as shown in FIG. Thereafter, the motor 40 rotates until returning to the standby state shown in FIG. 8A, and the motor 40 stops and one driving operation is completed. The timing at which the motor 40 stops in this way is measured by measuring a predetermined time after the microswitch 50 is turned on in the state shown in FIG. 10 and then turned off again. For example, in the case of a machine that enters a standby state when the motor 40 is operated for 0.5 seconds after the micro switch 50 is turned off, 0.5 seconds is measured after the micro switch 50 is turned off, and 0.5 seconds. The motor 40 is stopped later. If the micro switch 50 is not turned on even after a predetermined time has elapsed after the trigger 14 has been operated, or if the micro switch 50 does not turn off from the on state, the trigger 14 is not operating correctly or is not operating. An error is output because it is determined that the detection is not correct.

  Incidentally, as shown in FIG. 8B, the micro switch 50 according to the present embodiment is attached to the switch body 50a, the push button 50b protruding from the switch body 50a so as to be pressed, and the switch body 50a to be swingable. Swinging plate 50c. When the plunger 43 moves to the top dead center, as shown in FIG. 10, the engaging member 44 pushes up the swing plate 50c, and the push button 50b is pressed through the swing plate 50c.

  The switch body 50 a of the micro switch 50 is held by a switch holding part 52 provided in the tool body 11. Specifically, as shown in FIG. 9, a switch holding portion 52 provided in the housing of the tool body 11 holds the switch body 50a so as to sandwich the switch body 50a from both sides.

  However, when the state detection means (micro switch 50) for detecting the state (position) of the plunger 43 is attached to the tool body 11 in this way, the impact generated during driving is easily transmitted directly, and thus the electronic device such as the micro switch 50 is used. The member may be damaged. Therefore, in the present embodiment, a state detection means for detecting the state (position) of the plunger 43 is attached to the tool body 11 via an elastic member.

  In the example shown in FIG. 9, a rubber cushioning material 53 formed in a ring shape is used as the elastic member. In other words, the buffer material 53 is provided between the microswitch 50 and the switch holding portion 52. In this way, the shock absorbing material 53 is sandwiched and fixed, so that the shock (vibration) at the time of driving is not directly transmitted from the housing to the micro switch 50, and a shock absorbing effect can be obtained. Further, since the cushioning material 53 is an O-ring, it can cope with impacts in all directions as well as the front and back directions of the machine. By providing the buffer material 53 in this manner, the microswitch 50 can be prevented from being damaged by impact (vibration) at the time of driving, so that the life of the microswitch 50 can be extended. Further, chattering of the micro switch 50 can be prevented, and the reliability of the machine can be improved. Moreover, since it can respond to an increase in impact, even a machine with high output can be accommodated. In addition, it is possible to prevent an excessive contact load from being applied to the microswitch 50 at the time of contact with the plunger unit 42.

  In the present embodiment, the switch holding portion 52 is fixed to the housing of the tool main body 11. However, the present invention is not limited to this, and the micro switch 50 may be attached via other components such as the drive mechanism 41. Even in this case, the above-described effects can be obtained by attaching the microswitch 50 using the buffer material 53.

Moreover, in this embodiment, although the shock absorbing material 53 made from the O-ring is used as an elastic material, it is not restricted to this.
For example, as shown in FIG. 13A, a buffer material 53 in the form of a band may be used as the elastic material.

  Further, as shown in FIG. 13B, a buffer material 53 that is formed in a cylindrical shape and engages with the switch holding portion 52 may be used as the elastic material.

  Further, as shown in FIG. 14A, as an elastic material, a buffer material 53 made of resin (rubber or the like) and a buffer spring 54 which is a compression spring arranged so as to sandwich the microswitch 50 are used. May be.

  Further, as shown in FIG. 14B, only the buffer spring 54, which is a compression spring arranged so as to sandwich the microswitch 50 without using the resin-made buffer material 53 (such as rubber) as the elastic material. May be used.

  Further, as shown in FIG. 15, when using an O-ring cushioning material 53 made of a resin (such as rubber) as an elastic material, the switch holding portion 52 is not engaged with the switch holding portion 52. You may make it contact | abut to the end surface. Moreover, you may use such a buffer material 53 in combination with the buffer spring 54 which is a compression spring arrange | positioned so that the microswitch 50 may be inserted | pinched.

As described above, the following configuration is disclosed in this embodiment.
(Configuration 1) Driver 13 for driving out a nail, plunger 43 to which the driver 13 is attached and slidably arranged in the driving direction, and a state of detecting the state of the plunger 43 (for example, the position of the plunger 43) A driving tool, wherein the state detecting means is attached to the tool body via an elastic member.

  (Configuration 2) The driving tool according to Configuration 1, wherein the state detection means is fixed to a housing of the tool body via an elastic member.

  (Configuration 3) The driving tool according to Configuration 1 or Configuration 2, wherein the state detection means is a micro switch, and the elastic member is a rubber formed in a ring shape.

  As shown in FIG. 3, a magazine portion 20 is continuously provided behind the driver guide 16. This magazine part 20 is for accommodating the connecting nail 30, and guides the accommodated connecting nail 30 to the launch position (injection path).

  The magazine unit 20 includes a magazine main body 21, a cover body 22, a pusher 23, a pressing bar 24, a pressing bar urging member 25, and a foot tip guide 26.

  As shown in FIG. 2, the magazine body 21 is a long member fixed to the tool body 11 (specifically, the driver guide 16), and forms a nail guide path 20a together with a cover body 22 described later. .

  The cover body 22 is a long member having substantially the same length as the magazine body 21 and is attached to the magazine body 21 so as to be openable and closable as shown in FIG. The cover body 22 is slidable rearward with respect to the magazine body 21, and the nail guide path 20a is opened when the cover body 22 slides. When replenishing the connecting nail 30, the cover body 22 is slid in this way to open the nail guide path 20a, and the connecting nail 30 is inserted into the nail guide path 20a.

  As shown in FIGS. 4 and 7A, the pusher 23 is a plate-like member formed with substantially the same thickness as the connecting nail 30, and is formed between the magazine body 21 and the cover body 22. It is movable along the nail guide path 20a. The pusher 23 is always urged forward by an urging member (not shown), and when the pusher 23 presses the connecting nail 30 forward, the leading nail of the connecting nail 30 moves in the direction of the nose portion 15 (driving). It is sequentially supplied to the driver 13 immediately before the operation.

  As shown in FIG. 7A, the pressing bar 24 is a plate-like member arranged inside the cover body 22 along the nail feeding direction, and a plurality of (in this embodiment) the connecting nail 30 in the height direction. 4) are provided. The presser bar 24 is provided over the entire length of the nail guide path 20a, and can protrude into the nail guide path 20a in the direction of the magazine body 21 from the second support portion 22a as shown in FIG. ing. The pressing bar 24 is urged in the protruding direction by a pressing bar urging member 25 formed of a leaf spring or the like. For this reason, when the connecting nail 30 is loaded into the nail guide path 20a, the tip of the holding bar 24 is pressed against the connecting nail 30 as shown in FIG.

  The pressing bar 24 is for restricting the movement of the connecting nail 30 in the axial direction (vertical direction in FIG. 4), and a plurality of pressing bars 24 are provided so as to correspond to nails having different lengths. That is, as shown in FIG. 4, the pressing bar 24 that comes to the position of the nail head of the loaded connecting nail 30 protrudes to hold the nail head of the connecting nail 30, thereby restricting the axial movement of the connecting nail 30. To do. In the example shown in FIG. 4, the top pressing bar 24 presses the nail head of the connecting nail 30 to restrict the movement of the connecting nail 30 in the axial direction.

  The pusher 23 is shaped to avoid the pressing bar 24 so that the pressing bar 24 can press the nail head of the connecting nail 30. That is, as shown in FIG. 4, the upper end 23 a of the pusher 23 is located below the uppermost pressing bar 24 so that the uppermost pressing bar 24 does not hit. Further, a protrusion 23b protruding in the direction of the magazine main body 21 is provided at a position facing the other pressing bar 24. When the connecting nail 30 is loaded in the nail guide path 20a, the pusher 23 is The presser bar 24 is not hit.

  As shown in FIG. 4 and the like, the foot tip guide 26 is a member having a U-shaped cross section fixed to the magazine body 21, and is used for guiding the foot tip of the pusher 23 and the connecting nail 30 with a U-shaped groove. is there. The foot tip guide 26 is provided over the entire length of the nail guide path 20a.

  In order to stably support the connecting nail 30, the foot guide 26 alone is not sufficient. That is, if the depth of the groove of the foot tip guide 26 is increased, it becomes difficult to put in and out the nail. Therefore, the groove of the foot guide 26 is deep enough to guide only the foot of the nail. However, since nails used for pinnails and finish nailers are thin and the rigidity of the nails themselves is low, even if only the toes are held, the nails bend and overlap with the pusher 23 due to bending of the nails. In this regard, in the present embodiment, the first support portion 21a and the second support portion 22a, which will be described later, support the connecting nail 30 and the pusher 23 in the intermediate portion of the nail guide path 20a (in the present embodiment). The first support portion 21a and the second support portion 22a are provided closer to the nail head than the intermediate portion when the nail guide path 20a is viewed in the axial direction of the connecting nail 30). The nail and the pusher 23 can be prevented from overlapping without deepening the groove.

  That is, the magazine body 21 described above includes a first support portion 21a provided in a rib shape so as to abut one side surface of the connecting nail 30 accommodated in the nail guide path 20a, as shown in FIG. The cover body 22 includes a second support portion 22a provided in a rib shape so as to come into contact with the other side surface of the connecting nail 30 housed in the nail guide path 20a. The first support portion 21 a and the second support portion 22 a are arranged to face each other and extend along the feeding direction of the connecting nail 30. For this reason, the connecting nail 30 loaded in the nail guide path 20a is sandwiched and supported from both sides by the first support portion 21a and the second support portion 22a.

  At this time, the distance between the first support portion 21a and the second support portion 22a is set to be twice the width of the connection nail 30 so that the connection nail 30 cannot overlap and the pusher 23 cannot ride on the connection nail 30. The width is set not to exceed. By setting in this way, the width of the connecting nail 30 and the pusher 23 is defined by the first support portion 21a and the second support portion 22a. As shown in FIGS. 7A to 7C, the first support portion 21a and the second support portion 22a are provided over the entire length of the nail guide path 20a. The pusher 23 does not overlap or get on the nail.

  As shown in FIG. 6, the pressing bar 24 can move to a position indented from the second support portion 22 a and does not define the width of the connecting nail 30. The width of the connecting nail 30 is defined only by the first support portion 21a and the second support portion 22a.

  In addition, the first support portion 21a and the second support portion 22a described above are disposed between the plurality of pressing bars 24 as shown in FIG. In the present embodiment, it is disposed between the second pressing bar 24 and the third pressing bar 24 from the top. Thus, by arranging the first support portion 21a and the second support portion 22a in the intermediate portion, it is possible to effectively define the width of a short nail or a long nail.

  As described above, according to the present embodiment, the magazine body 21 includes the first support portion 21a that protrudes in a rib shape so as to be able to come into contact with one side surface of the connecting nail 30 accommodated in the nail guide path 20a. The cover body 22 includes a second support portion 22a protruding in a rib shape so as to contact the other side surface of the connecting nail 30 accommodated in the nail guide path 20a, and includes a first support portion 21a and a second support portion 22a. Is extended along the feed direction of the connecting nail 30. According to such a configuration, the width of the nail is determined by the two members of the magazine main body 21 (first support portion 21a) and the cover body 22 (second support portion 22a). The width of the nail will not increase. Therefore, there is no problem that the pusher 23 that tilts the nail and pushes the nail from the rear rides on the nail or the replenished connecting nail 30 rides on the existing nail. Can do.

  Further, since the width of the nail is determined by only two members, the magazine main body 21 and the cover body 22, the dimensional management of the parts is easy. Therefore, since a nail with a thin wire diameter is used, a problem is hardly caused even if the tool is severely dimensioned. As a conventional structure, there is one that determines the width of the nail by restricting the movable range of the presser bar 24. In such a structure, at least three parts of the magazine main body 21, the cover body 22, and the presser bar 24 are provided. Therefore, there is a problem that it is difficult to obtain the dimensional accuracy. In this respect, according to the present embodiment, since the dimensions can be managed with two parts, it is easy to obtain dimensional accuracy.

  Further, the second support portion 22 a is provided so as to be able to contact the pusher 23. That is, as shown in FIG. 4, the second support portion 22 a is provided at a position avoiding the protruding portion 23 b of the pusher 23, and the second support portion 22 a contacts the pusher 23 even when the connecting nail 30 is loaded. It is possible to contact. According to such a configuration, not only the connecting nail 30 but also the inclination of the pusher 23 can be suppressed, so that it is possible to prevent the pusher 23 from climbing onto the connecting nail 30 and causing a feeding failure.

  The cover body 22 is provided with a pressing bar 24 that can protrude in the direction of the magazine main body 21 relative to the second support portion 22a, and a pressing bar biasing member 25 that biases the pressing bar 24 in the protruding direction. Yes. According to such a structure, the vertical movement of the connecting nail 30 can be suppressed by the pressing bar 24 projecting.

  Further, the presser bar 24 is movable to a position that is recessed from the second support portion 22a. According to such a configuration, the movement of the nail can be suppressed by using the pressing bar 24. Further, since the pressing bar 24 does not relate to the maximum width of the nail, the pressing bar 24 does not require severe dimensional management, and the dimensional management of parts is easy.

  Further, the second support portion 22 a is disposed between the plurality of pressing bars 24. According to such a configuration, the width of the nail can be determined by the second support portion 22a corresponding to various nail lengths. That is, if the second support portion 22a is provided above all the pressing bars 24, the second support portion 22a may not face the nail when a short nail is used. Further, if the second support portion 22a is provided below all the pressing bars 24, there is a possibility that the inclination of the nail cannot be suppressed when a long nail is used (the width of the nail cannot be defined substantially). In this regard, if the second support portion 22a is disposed between the plurality of holding bars 24, the second support portion 22a can be made to face the side surface of the nail having various lengths, and the inclination of the nail is also effective. Can be suppressed.

  In the above-described embodiment, only one first support portion 21a and two second support portions 22a are provided. However, the present invention is not limited to this, and a plurality of first support portions 21a and second support portions 22a are provided. May be.

  In the above-described embodiment, the configuration in which the pressing bar 24 is provided on the cover body 22 has been described. However, the present invention is not limited to this, and the pressing bar 24 may be provided on the magazine body 21 as in the present embodiment. The effect is obtained.
