Description

  The present invention relates to a nailing machine including a linear magazine that accommodates a connecting nail linearly connected by a connecting band such as a plastic material so that shaft portions are parallel to each other, and in particular, the magazine. The present invention relates to a nail supply mechanism for a nailing machine in which connecting nails accommodated therein are sequentially fed into an injection port formed in a nose portion of the nailing machine.

  In a nailing machine in which nails are driven through an impact mechanism driven by power such as compressed air, a plurality of nail shafts aligned in parallel with each other in order to drive a large number of nails continuously. Coiled connection nails that are connected to each other by a flexible connection band and wound in a spiral shape, or a shaft portion of a nail that is arranged in a planar shape so that the shaft portions are parallel to each other, plastic material or plastic material and paper And a linear connecting nail connected in a straight line by a connecting band formed in layers. In the case of relatively small-sized nails, it is generally formed as a coiled connecting nail, and a large amount of nails can be loaded into a cylindrical magazine of the nailing machine so that the nailing operation is continued. Can be done. For nails with large dimensions, the coiled coiled nail shape that can be wound in a coil shape increases the coiled coil shape, necessitates a large magazine and increases the weight when the nail is loaded, There is a problem that workability is impaired.

  For this reason, in the case of a nail having a relatively large size, 20 to 30 nails are juxtaposed on a plane such that the nail shafts are parallel to each other, and a curable adhesive such as plastic is provided between the shaft portions of each nail. A connecting nail that is filled and connected linearly is used. In a nailing machine using such a linear connecting nail, a straight line that accommodates the connecting nail linearly connected to the nose portion attached to the lower part of the body housing the impact mechanism for hitting the nail. A continuous magazine is connected continuously, and the connecting nails loaded in the magazine are sequentially supplied into the injection port formed in the nose portion, and the inside of the injection port is struck by a driver of an impact mechanism that is driven impactively. I am trying to launch from the injection port.

  As a general nail supply mechanism for supplying the nail loaded in the linear magazine to the nose portion, a pusher member spring-biased in the direction of the injection port is slidably provided in the magazine, The pusher member is engaged with the last nail of the connecting nail loaded in the magazine, and the whole connecting nail is pressed toward the injection port by the spring biasing force of the pusher member, and the leading nail of the connecting nail is moved. Supply to the injection port. In such a nail supply mechanism, when the connecting nail is loaded into the magazine, the pusher member is pulled back to the back of the magazine, the connecting nail is loaded in front of the pusher member, and then the pusher member is loaded again. There is a problem that it is necessary to perform an operation to engage the last nail of the connecting nail, and the operation of loading the connecting nail becomes troublesome.

A nailing machine that uses a coiled connecting nail on one nail supply guide wall of a linear magazine that accommodates the connecting nail in order to eliminate the troublesome loading operation of the nail supply mechanism by the pusher member as described above A nail supply mechanism having a feed claw that reciprocates along a nail supply guide wall, which is substantially the same as that adopted in the above, is formed, and the connection claw of the nail supply mechanism is accommodated in a magazine There has already been proposed a magazine in which the connecting nails in the magazine are sequentially transferred toward the injection port of the nose portion by being engaged with the nail shaft of the nail and the leading nail of the connecting nail is supplied into the injection port. By forming the nail supply mechanism along one side wall of the magazine in this way, the loading operation can be completed simply by loading the connecting nail from the rear of the magazine without having to pull back the pusher member. Can be performed easily and in a short time, and the workability of nailing is not hindered.
JP 59-88268 A

  As described above, in the nail supply mechanism having a feed claw that reciprocates along the nail supply guide wall, when the feed claw that reciprocates along the side wall of the magazine moves backward, it engages with the feed claw. In order to prevent the connected nail from being retracted, a nail stopper (a check member) is provided that engages with the nail shaft of the connected nail, and the leading end of each of the nail stoppers and the nail stopper is loaded in the magazine. It is spring-biased so that it can be engaged with the nail shaft of the connecting nail, and the inclined surface is formed on the rear side surface of these nails, so that the connecting to be loaded into the magazine from the rear end side of the magazine When the nail engages with the inclined surfaces of the nail stopper and the feed claw, the nail is operated to retract the feed claw and the nail stopper from the magazine, and the connecting nail is loaded to the front end position of the magazine.

  In a nailing machine in which linearly connected connecting nails are loaded into a linear magazine, when the last nail of the connected nails loaded in the magazine is fed into the injection port of the nose, If the nail of the product falls from the injection port before being hit by the driver, or the tip is tilted backwards in the injection port, it will cause adverse effects, so leave multiple nails in the magazine. An idle driving prevention mechanism for stopping the driving of the nailing machine is operated. For this purpose, a nail detection member is arranged along the nail guide wall surface of the magazine, and this nail detection member is operated by not being engaged with the nail when the remaining number of nails in the magazine reaches a predetermined number. The nailer is not activated. Therefore, normally, a new connecting nail is loaded with a predetermined number of connecting nails remaining in the magazine.

  In the conventional nail supply mechanism, even if the leading nail of the loaded connecting nail is loaded up to the position where it engages with the nail stopper, the leading nail of this connecting nail cannot be engaged with the feeding nail, Therefore, even when the nail supply mechanism is operated and the feed claw is reciprocated in the nail supply direction, a state in which the loaded connection nail is not supplied in the direction of the injection port occurs. If the leading nail of the connecting nail loaded in the magazine is loaded to the position where it engages with the feed claw, the leading nail cannot be engaged with the nail stopper. A state occurs in which the connecting nail reciprocates together with the feeding claw and is not supplied forward. Furthermore, even when the loaded connecting nail is loaded to the position where it is engaged with the feed claw and the nail stopper, if the connected nail is not engaged with the nail detection bar, the remaining number of nail is recognized as the predetermined number, and empty. The nail driver cannot be started because the hit prevention mechanism is activated, and the connecting nail is engaged with the nail detection member in the state where the connecting nail is not engaged with the feed nail and the nail stopper, so If the prevention mechanism does not operate and the nail driver is ready to be activated, the nail is not supplied and the nail driver is activated and idle driving may occur.

  The present invention solves the above-mentioned problems in the prior art, and loads the connecting nail from the rear end of the magazine to the position where the leading nail of the connecting nail engages with the check nail. It is an object of the present invention to provide a nail supply mechanism for a nailing machine that can be reliably supplied by a feed claw.

  In order to solve the above problems, a nail supply mechanism of a nailing machine according to the present invention includes a nose portion that forms a hollow injection port that slides and guides a driver that strikes the nail, and a rear side of the injection port of the nose portion A nail supply guide that is integrally connected to the side, and a linear magazine that is connected to the rear end of the nail supply guide and that is connected linearly. A nailing machine that sequentially supplies the connecting nails loaded from the opened rear end side of the magazine into the injection port of the nose portion, and drives the nail supplied into the injection port from the injection port by the driver. In this nail supply mechanism, a feed member that reciprocates along the supply direction of the connecting nail is provided on one side wall of the nail supply guide that is connected to the injection port, and the feed nail formed on the feed member is loaded into the magazine. Engage with each nail shaft In this way, the connecting nail is sequentially supplied into the injection port, and further provided with a claw member that engages with each nail of the connecting nail loaded in the magazine, and the claw member is engaged with the nail of the connecting nail. Is provided with a check member that prevents the connecting nail from moving backward, and the position of the nail member of the check member is moved to the most retracted position in the connecting nail supply direction. It is characterized by being arranged so as to substantially coincide with the position of the feed claw.

  Further, in the invention of claim 2, the nail supply mechanism further engages / disengages with the connection nail loaded along the nail supply guide, and the remaining number of connection nails in the magazine becomes a predetermined number or less. The nail detection member is sometimes arranged so as not to start the nailing machine, and the nail at the head of the connecting nail loaded in the magazine is loaded to the position where it engages with the nail member of the check member. The nail detection member is arranged so that the nail detection member is actuated by the connecting nail so that the nail driver can be activated.

  According to the nail supply mechanism of the nail driver of the present invention, the nail supply mechanism is provided with a feed member that reciprocates along the supply direction of the connecting nail on one side wall of the nail supply guide that is continuously provided to the injection port. The connecting claws formed on the feeding member are engaged with the nail shafts of the connecting nails loaded in the magazine so that the connecting nails are sequentially supplied into the injection port, and the connecting nails loaded in the magazine are further provided. A non-return member that includes a claw member that engages with each of the nail and that prevents the rearward movement of the connecting nail by engaging the nail member with the nail of the connecting nail. Since the position of the claw member is substantially aligned with the position of the feed claw when the nail feed member is moved to the most retracted position in the connection direction of the connection nail, the top nail of the connection nail is the check member From the rear end of the magazine to the position where it engages with the check pawl When the feed claw of the nail feed member that reciprocates along the nail supply guide is actuated to the rear end side, the feed claw is moved to the top of the connecting nail. The connecting nail can be fed forward when the feed member is engaged forward and the feed member operates forward. In this way, by loading the connecting nail to the position where it engages with the check claw, the connecting nail does not come out from the magazine to the rear side, and when the nail driver is started, the feeding nail It is possible to engage with the nail shaft of the connecting nail and to reliably supply the connecting nail toward the injection port.

  According to a second aspect of the present invention, the nail supply mechanism further engages and disengages from the connection nail loaded along the nail supply guide, so that the remaining number of connection nails in the magazine is less than a predetermined number. The nail detection member that operates so as not to start the nail driver when it has become, is arranged to the position where the leading nail of the connecting nail loaded in the magazine engages with the nail member of the check member Since the nail detection member is arranged so that the nail detection member can be activated by the connection nail when the nail is loaded, the top nail of the connection nail loaded from the rear end of the magazine If the nail driver is started in this state at a position where it is not engaged with the claw member of the check member, the connecting nail is not engaged with the feed claw of the nail feed member, so that it can be supplied in the direction of the injection port. However, the nail detection member can engage with the connecting nail. Thus it is possible to prevent blank beating occurs because the nail detecting member is set to a state that can not start the nailing machine operates. Further, when the connecting nail is loaded up to the position where it engages with the nail member of the check member, the nail detection member engages with the connecting nail and operates so that the nail driver can be activated. Activation and connection nail supply.

  The object of the present invention is to reliably supply the loaded connection nail by the feed nail by loading the connection nail from the rear end of the magazine to the position where the leading nail of the connection nail engages with the check nail. A feed member that reciprocates along the supply direction of the connecting nail is provided on one side wall of the nail supply guide that is connected to the injection port, and each nail shaft of the connecting nail loaded in the magazine with the feed nail formed on the feed member The nail is sequentially supplied into the injection port by engaging with the nail, and further includes a claw member that engages with each nail of the nail loaded in the magazine, and the nail member is engaged with the nail of the nail. A non-return member that prevents the connecting nail from moving rearward by combining the nail feeding member, and the nail member of the non-return member is moved to the most retracted position in the connecting nail supply direction. Arrange it almost in line with the position of the feed claw. Are those realized by, illustrating more specific examples below.

  FIG. 1 is a side view showing a main part of a nailing machine using compressed air as a power source in which a nail supply mechanism of the present invention is implemented, and a nose attached to a housing containing an impact mechanism composed of a piston, a cylinder and the like. The part 1 is formed with a hollow injection port 2 for slidably receiving a driver driven by an impact mechanism. An opening 3 for introducing a nail into the injection port 2 is formed on the rear side of the injection port 2, and one side edge of the opening 3 extends integrally with the nose portion toward the rear side. A nail supply guide 4 is formed. The leading nail of the connection nail supplied along the guide surface 5 of the nail supply guide 4 is guided into the injection port 2 through the opening 3, and the nail supplied into the injection port 2 is driven by an impact mechanism. The driver is struck and driven out from the injection port 2.

  The rear end of the nail supply guide 4 can accommodate connecting nails in which the nail shafts are arranged in parallel on a plane so that the nail shafts are linearly connected by a curable adhesive such as plastic. A linearly formed magazine 6 is continuously provided rearward, and a guide surface 7 formed by an inner wall surface of the magazine 6 is flush with the guide surface 5 of the nail supply guide 4. The connection nail accommodated in the magazine 6 is guided and guided into the injection port 2 of the nose portion 1 by the guide surface 7 and the guide surface 5 of the nail supply guide 4. Further, as shown in FIGS. 2 and 3, a door member 8 is formed so as to face the guide surface 5 of the nail supply guide 4 and the guide surface 7 of the magazine 6, and the door member 8 is formed of the guide surface. 5 and the guide surface 7 are arranged at a predetermined interval, and an accommodating portion 9 for accommodating the connecting nail is formed between the inner surface of the door member 8 and the guide surface 7. The accommodating portion 9 is open at the rear end side, and the connecting nail is loaded from the rear end side of the magazine 6 into the accommodating portion 9 formed between the door member 8 and the guide surface 7 of the magazine 6. I have to.

  The nail supply guide 4 is formed with a nail supply mechanism 10 for sequentially supplying the connecting nails loaded in the accommodating portion 9 of the magazine 6 in the direction of the injection port 2 of the nose portion 1. The nail supply mechanism 10 has a feed claw 12 that is reciprocated along the supply direction and engages with a nail shaft of the connection nail loaded in the magazine 6 to supply the connection nail in the direction of the injection port 2. And a check member for preventing the connecting nail from moving rearward when the nail feeding member 11 is operated rearward. The nail feeding member 11 is engaged with the nail shaft of the connecting nail. 13. The nail feed member 11 is slidably disposed in an opening 15 formed in the nail supply guide 4, and is inserted into the opening 15 by a nail feed operation mechanism 16 formed on the back side of the nail supply guide 4. The feed claw 12 formed on the nail feed member 11 is engaged with the connection nail disposed along the nail supply guide 4 to reciprocate the nail in the nail supply direction. Supply in the direction.

  Further, the nose portion 1 is provided with a contact member 17 slidably supported along the injection port 2 formed in the nose portion 1, and the tip of the contact member 17 is the nose portion 1. The contact member 17 is configured to be operated by pressing the tip of the injection port 2 of the nose portion 1 against the workpiece. A contact arm 18 is connected to the contact member 17, and an upper end 18a of the contact arm 18 is arranged in the vicinity of a trigger lever for starting the nailing machine. The nailing machine is started by operating both the trigger lever operated by a person's finger. The nail supply guide 4 is provided with a nail detection member 19 that operates when the remaining number of connecting nails loaded in the magazine 6 reaches a predetermined number. When the remaining number of the nail reaches a predetermined number, the nail detection member 19 operates so as to block the operation of the contact arm 18 connected to the contact member 17, and the nail driver is not activated. I am doing so.

  As shown in FIG. 4, the connecting nail N linearly connected in the magazine 6 in a normal state has the head of each nail of the connecting nail N formed in the magazine 6 and the nail supply guide 4. Housed in the head guide groove 20 and guided in the direction of the injection port 2 of the nose portion 1, the tip of the leading nail of the connecting nail N abuts against the inner wall surface in front of the injection port 2 of the nose portion 1. Is loaded with its head tilted slightly to the rear. Then, the driver D driven by the impact mechanism strikes the head of the leading nail of the connecting nail N, dissociates the leading nail from the connected state, and drives it toward the tip of the injection port 2.

  As shown in FIG. 5, the nail feed member 11 is rotatably held by an operating rod 21 that is reciprocated in the nail supply direction by a nail feed actuating mechanism 16, and the tip of the feed claw 12 of the nail feed member 11. Is elastically biased so as to protrude from the opening 15 toward the guide surface 5 of the nail supply guide 4. When the nail feed member 11 is actuated by the actuating rod 21 in the nail supply direction, the feed claw 12 is engaged with the nail shaft of the connecting nail N loaded along the guide surface 5 of the nail supply guide 4. The connecting nail N is supplied in the direction of the injection port 2 of the nose portion 1. Further, an inclined surface 22 is formed on the rear side surface of the feed claw 12, and when the nail feed member 11 is operated to the rear side in the nail supply direction by the operating rod 21, the inclined surface 22 of the feed claw 12 is on the rear side. By engaging the nail shaft, the nail feed member 11 is rotated so that the feed claw 12 is retracted from the guide surface 5 of the nail supply guide 4 against the elastic biasing force, and the nail feed member 11 is moved backward. Move to the side.

  As shown in FIG. 6, the check member 13 is rotatably supported on the back side of the nail supply guide 4, and the claw member 14 formed at the tip of the check member 13 is the nail supply guide 4. The nail supply guide 4 is biased so as to protrude from the opening 23 formed on the guide surface 5 side. When the tip of the claw member 14 is engaged with the nail shaft portion of the connection nail N arranged along the guide surface 5 of the nail supply guide 4, the connection nail N moves to the rear side of the magazine 6. I try to stop it. Further, an inclined surface 24 is formed on the rear side of the tip of the claw member 14, and when the connecting nail N is supplied in the direction of the injection port 2 by the nail feeding member 11, the inclined surface 24 is connected to the connecting nail N. It is made to engage with the shaft part. When the inclined surface 24 is engaged with the shaft portion of the nail, the check member 13 is rotated against the rotation urging force so that the tip of the nail member 14 is retracted from the guide surface 5 of the nail supply guide 4. The movement of the connecting nail N to the front is allowed. The claw member 14 is disposed so as to be substantially in the same position as the feed claw 12 of the nail feed member 11 when the nail feed member 11 is moved to the most retracted position. When the lever is retracted, the feed claw 12 engages with the claw member 14 of the check member 13 so as to engage with the nail shaft.

  As shown in FIG. 7, the nail detection member 19 is rotatably supported by a support shaft 25 on the back side of the nail supply guide 4, and an end portion of the nail detection member 19 is formed on the nail supply guide 4. It is configured to be rotated and urged by a spring 27 so as to protrude from the opening 26 that is present toward the guide surface 5 side. As shown in FIG. 7, when the remaining number of the connection nails N in the magazine 6 is large, the end of the nail detection member 19 is rotated so as to engage with the connection nail N and retract from the guide surface 5. In this state, the contact arm 18 is allowed to be operated, and the nail driver is activated by the contact arm 18 operated by the contact member 17.

  As shown in FIG. 8, when the remaining number of connecting nails N loaded in the magazine 6 is reduced to a predetermined number, the nail detecting member 19 becomes unable to engage with the connecting nails N, and the nail detecting member 19 Is rotated by a spring 27 so that the end of the nail feeds toward the guide surface 5 side of the nail supply guide 4. When the nail detection member 19 is rotated to this position by the spring biasing force, the nail detection member 19 engages with the contact arm 18 and thereby prevents the operation of the contact arm 18. Therefore, even if the contact member 17 is operated, the contact arm 18 does not operate, so that the nail driver is not started. This prevents damage to the tool due to idle driving and prevents the last nail of the connecting nail N from being driven out in an unstable posture. The nail detection member 19 is arranged so that the rear end side of the nail detection member 19 can be engaged with the connection nail N that is prevented from moving backward by the claw member 14 of the check member 13. When the nail N is loaded into the magazine 6 to the position where the nail N is engaged with the check member 13, the nail driver is set to be activated.

  FIG. 9 shows a state in which the remaining number of connected nails N1 loaded in the magazine 6 is reduced, the nail detection member 19 is activated, and the nailing machine cannot be started, and a new connected nail N2 is loaded into the magazine 6. In this case, the head of each nail of the connecting nail N2 is received and loaded in the head guide groove 20 formed in the magazine 6 from the rear end of the magazine 6, and the newly loaded connection is obtained by this loading operation. The leading nail of the nail N2 engages with the inclined surface 24 of the claw member 14 of the check member 13 to retract the claw member 14 from the guide surface 5, and the shaft portion of the leading nail of the connecting nail N2 is checked. The member 13 is loaded up to a position where it is disposed on the front side of the claw member 14. When the leading nail of the new connecting nail N2 is loaded to the position where it engages with the nail member 14 of the check member 13, as shown in FIG. Since the tip of the claw member 14 of the member 13 enters and the claw member 14 and the nail shaft can be engaged with each other, the connecting nail N cannot be extracted rearward.

  Further, since the claw member 14 of the check member 13 is disposed at substantially the same position as the feed claw 12 when the nail feed member 11 is moved to the most retracted position, as shown in FIG. When the leading nail is loaded to the position where it engages with the claw member 14 of the check member 13, the nail driving device is activated and the nail feed member 11 is moved to the most retracted position by the nail feed operation mechanism 16. Further, the feed claw 12 of the feed member 11 is engaged with the rear side of the nail shaft engaged with the claw member 14, and thereafter, the nail feed member 11 is moved forward by the nail feed operation mechanism 16. Accordingly, the connecting nail N2 engaged with the feed claw 12 is supplied in the direction of the injection port 2 of the nose portion 1. In this way, by loading the new connecting nail N2 to the position where it engages with the claw member 14 of the check member 13, the connecting nail N2 does not come out from the magazine 6 to the rear side, and further the nail driver Thus, the feeding nail 12 of the nail feeding member 11 can be engaged with the nail shaft of the coupling nail N2 and the loaded coupling nail N2 can be reliably supplied toward the injection port 2.

  Further, as shown in FIG. 12, in the state in which the shaft portion of the leading nail of the new connecting nail N2 is loaded to the position where it is arranged on the front side of the claw member 14 of the check member 13, the rear side of the nail detection member 19 is inserted. The nail detection guide 19 is engaged with the nail N2 whose end side is engaged with the claw member 14 of the check member 13 and prevented from moving backward, and the nail detection member 19 resists the spring biasing force. 4 so that the nailing machine can be started by rotating in the direction of retraction from the guide surface 5, so that the leading nail of the connecting nail N 2 is loaded to a position where it can engage with the claw member 14 of the check member 13. Thus, the idle driving prevention mechanism is released and the nail driver can be started, and the connecting nail N2 can be reliably supplied to the injection port 2 of the nose portion 1 by the nail feeding member 11. In addition, when the leading nail of the connecting nail N2 is loaded only to the position where it does not engage with the claw member 14 of the check member 13, the nail detection member 19 is advanced to the guide surface 5 side to activate the nail driver. Since it is set to a state where it cannot be performed, it is possible to prevent the occurrence of idle shots.
