Embodiments for Carrying Out the Invention

[0012] (Embodiment 1) The work machine system 90 of the present Embodiment 1 includes, for example, a first work machine shown in FIGS. 1 to 3, a second work machine shown in FIG. 4, and a detection unit 54 that can be attached to any of the first work machine and the second work machine. That is, the work machine system 90 is a system that improves the convenience of the work machine by unitizing a plurality of parts attached to the work machine and providing a unit that can be attached to any of a plurality of work machines such as the first work machine and the second work machine. The first work machine and the second work machine taken up in the present Embodiment 1 are pneumatic nailers 10.

[0013] Among the pneumatic nailers 10, the first work machine is a nailer 10a of a type in which the extending direction of a magazine part 77 capable of accommodating a plurality of fasteners is inclined with respect to the reciprocating direction of a striking part 12 for driving the fasteners. Hereinafter, in the present Embodiment 1, the nailer (first work machine) 10a of the above type will be referred to as an angle type nailer 10a.

[0014] On the other hand, among the pneumatic nailers 10, the second work machine is a nailer 10b of a type in which the extending direction of a magazine part 77 capable of accommodating a plurality of fasteners is orthogonal to the reciprocating direction of a striking part 12 for driving the fasteners. Hereinafter, in the present Embodiment 1, the nailer (second work machine) 10b of the above type will be referred to as a straight type nailer 10b.

[0015] First, the angle - type driving machine (first working machine) 10a shown in FIGS. 1 to 3 will be described. The driving machine 10a has a housing 11, a striking part 12, an injection part 13, a power supply part 14, an electric motor 15, a speed - reducing mechanism 16, a winding - up mechanism 17, and a pressure - accumulating container 18. The housing 11 is an outer - shell element of the driving machine 10a and has a cylinder case 19, a handle 20, a motor case 21, and a mounting part 22. The cylinder case 19 is cylindrical, and the handle 20 and the motor case 21 are connected to the cylinder case 19. Also, the mounting part 22 is connected to the handle 20 and the motor case 21. Specifically, one end of the mounting part 22 is connected to the handle 20, and the other end on the opposite side is connected to the motor case 21 via an extension part 21a. The power supply part 14 is detachably mounted on the mounting part 22.

[0016] In the first embodiment, the direction in which the cylinder case 19 extends is defined as the vertical direction (first direction) M1, and the direction orthogonal to the vertical direction (first direction) M1 is defined as the left - right direction R1. Also, a direction orthogonal to both the vertical direction (first direction) M1 and the left - right direction R1 and in which the motor case 21 extends is defined as the front - rear direction (fourth direction) N1. Further, the extending direction of the magazine part 77 is defined as the second direction P1.

[0017] Inside the cylinder case 19, a cylinder 27 is accommodated. The cylinder 27 is made of metal, for example, aluminum or iron. The cylinder 27 is positioned in the direction along the center line A1 and the radial direction with respect to the cylinder case 19. The center line A1 passes through the center of the cylinder 27. The radial direction is the radial direction of a virtual circle centered on the center line A1.

[0018] The housing 11 has a two - part structure on the left and right, and the housing 11 located on the right side and the housing 11 located on the left side are fixed by a plurality of screws.

[0019] In addition, a head cover 25 is attached to the cylinder case 19, and an accumulator 18 having a cap 23 is disposed across the inside of the cylinder case 19 and the inside of the head cover 25. A cylinder 27 disposed in the cylinder case 19 is supported by a holder 24, and the holder 24 is connected to the cap 23. Thereby, a pressure chamber 26 is formed across the inside of the accumulator 18 and the inside of the cylinder 27. The pressure chamber 26 is filled with a compressed gas. The compressed gas filled in the pressure chamber 26 biases the striking portion 12 downward in the vertical direction M1.

[0020] The striking portion 12 is disposed across the inside and the outside of the housing 11 and has a piston 28 and a driver blade 29. The piston 28 is operable in the vertical direction M1 within the cylinder 27. The piston 28 and the driver blade 29 are provided as separate members and are connected to each other. Therefore, the striking portion 12 can strike a nail (fastener) 78 by moving downward in the vertical direction M1.

[0021] The ejection portion 13 includes a portion where the nail 78 is supplied, a nose portion 32 that supports the cylinder 27, a blade guide 34 that guides the movement of the driver blade 29, and a guide plate 39 that forms an ejection path 37 between the blade guide 34.

[0022] The driver blade 29 is disposed within the guide hole of the bumper support portion 31 and within the guide hole 36 of the bumper 35. The striking portion 12 is operable in the vertical direction M1 and is constantly biased downward by the pressure of the compressed gas in the pressure chamber 26. The ejection portion 13 has an ejection path 37 in which the nail 78 is disposed, and the ejection path 37 is provided along the vertical direction M1. The driver blade 29 is operable in the vertical direction M1 within the ejection path 37 and strikes the nail 78 supplied to the ejection portion 13 downward in the vertical direction (first direction) M1.

[0023] In addition, a push lever 79 is attached to the nose portion 32. The push lever 79 can operate within a predetermined range in the vertical direction M1 with respect to the nose portion 32. The push lever 79 is a switch member. Specifically, it can move from the first position (switch-off position) to the second position (switch-on position) by contacting the mating member 30. Note that the push lever 79 is constantly biased downward in the vertical direction M1 by an elastic member (not shown). Therefore, when the tip of the push lever 79 is not pressed against the mating member 30, it is always in the first position (switch-off position). On the other hand, when the tip of the push lever 79 is pressed against the mating member 30 and moves to a predetermined position (second position) above the first position, the switch is turned on.

[0024] Also, an electric motor 15 is disposed within the motor case 21. The electric motor 15 is, for example, a brushless motor, and the rotation axis of the electric motor 15 rotates about the center line A2. Further, a speed reduction mechanism 16 to which power is transmitted from the rotation axis of the electric motor 15 is provided within the motor case 21. The speed reduction mechanism 16 includes a plurality of sets of planetary gear mechanisms and is a mechanism that decelerates and outputs the input element from the electric motor 15 in the power transmission path.

[0025] The power of the electric motor 15 is decelerated by the speed reduction mechanism 16 and transmitted to the winding-up mechanism 17. The winding-up mechanism 17 converts the rotational force of the rotation axis of the electric motor 15 into a force that biases the striking portion 12 upward in the vertical direction M1. Specifically, the winding-up mechanism 17 includes a pin wheel 50 that engages with the driver blade 29, and the pin wheel 50 rotates by the power of the electric motor 15. That is, the pin wheel 50 rotates by the power of the electric motor 15, and the rotation of the pin wheel 50 pushes the driver blade 29 after driving upward in the vertical direction M1. The pin wheel 50 is housed in the pin wheel housing portion 33.

[0026] Also, a magazine unit 77 is provided alongside the motor case 21. The magazine unit 77 of the driving machine 10a is attached such that the extending direction (second direction P1) of the magazine unit 77 is inclined with respect to the reciprocating direction (vertical direction M1) of the striking unit 12. The magazine unit 77 can accommodate a plurality of nails 78. The front end of the magazine unit 77 is supported by the nose portion 32, and the rear end is supported by the mounting portion 22. The magazine unit 77 is provided with a feeder unit (detected unit, biasing unit) 55 that sequentially feeds the plurality of accommodated nails 78 toward the shooting path 37. The feeder unit 55 is movable along a rail portion 76 provided in the magazine unit 77 in the extending direction (second direction P1) of the magazine unit 77. Thereby, the plurality of nails 78 accommodated in the magazine unit 77 are sent to the shooting path 37 of the shooting unit 13 by the feeder unit 55. That is, the nails 78 are supplied from the magazine unit 77 to the shooting unit 13 by the feeder unit 55. In other words, the feeder unit 55 moves in the direction approaching the shooting unit 13 in the extending direction (second direction P1) of the magazine unit 77 in conjunction with the supply of the nails 78.

[0027] Also, the driving machine 10a is provided with a trigger 53 and a trigger sensor (not shown). The trigger 53 and the trigger sensor are provided on the handle 20. The trigger sensor detects the presence or absence of an operating force applied to the trigger 53 and outputs a signal according to the detection result.

[0028] Also, a controller 82 is provided inside the mounting portion 22. The controller 82 mainly controls the drive of the electric motor 15. The controller 82 has a microprocessor. Also, inside the motor case 21, a circuit board having an inverter circuit is provided. The inverter circuit includes a plurality of switching elements, and each of these plurality of switching elements can be turned on and off. The controller 82 controls the inverter circuit to control the rotation and stop of the electric motor 15, or the rotation speed and rotation direction of the electric motor 15.

[0029] Next, an operation example of the driver 10a will be described. When the controller 82 detects at least one of the following conditions: that no operating force is applied to the trigger 53, or that the push lever 79 is not pressed against the workpiece 30, the controller 82 stops supplying power to the electric motor 15. For this reason, the electric motor 15 stops, and the striking portion 12 stops at the standby position.

[0030] When the controller 82 detects that an operating force is applied to the trigger 53 and that the push lever 79 is pressed against the workpiece 30, the controller 82 applies a voltage from the power supply unit 14 to the electric motor 15 and rotates the electric motor 15 in the forward direction. Thereby, the driving operation is started. In other words, unless the controller 82 detects both that an operating force is applied to the trigger 53 and that the push lever 79 is pressed against the workpiece 30, the controller 82 does not output a signal for applying a voltage from the power supply unit 14 to the electric motor 15, and does not start the driving operation.

[0031] When the driving operation is started, the electric motor 15 starts. The rotational force of the electric motor 15 is transmitted to the pin wheel 50 via the speed reduction mechanism 16. When the pin wheel 50 rotates in a predetermined direction, the striking portion 12 rises. When the striking portion 12 rises, the gas pressure in the pressure chamber 26 rises.

[0032] When the final pin in the rotation of the pin wheel 50 in the predetermined direction separates from the final rack of the driver blade 29, the striking portion 12 descends due to the gas pressure in the pressure chamber 26. When the striking portion 12 descends due to the gas pressure in the pressure chamber 26, the driver blade 29 strikes one nail 78 positioned in the ejection path 37, and the nail 78 is driven into the workpiece 30.

[0033] Next, a straight-type driving machine (second working machine) 10b shown in FIG. 4 will be described. Similar to the angle-type driving machine 10a, the driving machine 10b also has a housing 11, an injection unit 13, and a power supply unit 14, and has a striking unit 12, an electric motor 15, a speed reduction mechanism 16, a hoisting mechanism 17, and a pressure accumulator 18 shown in FIGS. 2 and 3. That is, the driving machine 10b shown in FIG. 4 includes a pressure chamber 26 formed by the pressure accumulator 18 and the cylinder 27 as shown in FIGS. 2 and 3, and has a striking unit 12 disposed in the cylinder 27. Then, the nail 78 is struck and driven by the striking unit 12 that descends due to the gas pressure in the pressure chamber 26.

[0034] As described above, since the internal structure of the driving machine 10b and the striking operation of the striking unit 12 are the same as those of the driving machine 10a, the detailed description thereof will be omitted.

[0035] The difference between the driving machine 10b and the driving machine 10a is that a magazine unit 77 capable of accommodating a plurality of nails 78 is provided such that its extending direction (second direction P1) is orthogonal to the reciprocating direction (vertical direction M1) of the striking unit 12. In other words, the magazine unit 77 of the driving machine 10b is provided such that its extending direction (second direction P1) is parallel to the front-rear direction N1. Stated in yet another way, the magazine unit 77 of the driving machine 10b is provided such that its extending direction (second direction P1) is substantially parallel to the extending direction of the motor case 21.

[0036] Next, the detection unit 54 included in the working machine system 90 of the first embodiment will be described. The detection unit 54 is a unit for detecting nails, which can be attached to both the first working machine (driving machine 10a) and the second working machine (driving machine 10b). It is attached to the first working machine and the second working machine to detect the remaining amount of the nails 78 accommodated in the magazine unit 77.

[0037] The detection unit 54 is provided in the magazine unit 77 and includes a feeder unit (detected unit, biasing unit) 55 that biases the nail 78 toward the injection unit 13 on the side close to the injection unit 13 in the second direction P1 which is the extending direction of the magazine unit 77, and a sensor unit (detection unit) 57 that detects the remaining amount of the nails 78 accommodated in the magazine unit 77 by contacting the feeder unit 55 and detecting the feeder unit 55. That is, the detection unit 54 is a unit for detecting the remaining amount of nails composed of the feeder unit 55 and the sensor unit 57.

[0038] The feeder unit 55 is provided on the rail unit 76 of the magazine unit 77 and is movable along the extending direction P1 of the magazine unit 77 while being guided by the rail unit 76. Further, the feeder unit 55 is a member that biases a plurality of nails 78 accommodated in the magazine unit 77 by the biasing force of a spring (not shown) and sequentially sends out the nails 78 to the side close to the injection unit 13. The feeder unit 55 also includes a contact portion 56 that contacts the sensor unit 57 in the process of the feeder unit 55 moving to the side close to the injection unit 13. Specifically, the contact portion 56 is a portion that contacts the sensor unit 57 when the remaining amount of the nails 78 reaches a set predetermined number in the process of the feeder unit 55 moving to the side close to the injection unit 13. Due to the contact between the sensor unit 57 and the contact portion 56 of the feeder unit 55, the switch of the sensor unit 57 is turned on, and a signal notifying the controller 82 that the remaining amount of the nails 78 has reached the predetermined number is transmitted from the sensor unit 57.

[0039] On the other hand, the sensor unit 57 has a fixed portion 58 that is fixed to at least one of the injection unit 13 or the magazine unit 77, and this fixed portion 58 is fixed to at least one of the injection unit 13 or the magazine unit 44 by a screw (fastening tool) 59. In the first embodiment, the case where the fixed portion 58 of the sensor unit 57 is fixed to the injection unit 13 will be described.

[0040] As shown in FIGS. 5 and 6, the sensor unit 57 includes a movable part 57a that moves along the second direction P1, a spring (elastic body) 57b that biases the movable part 57a in a direction away from the injection part 13a in the second direction P1, a magnet 57c built into the movable part 57a, and a Hall IC (sensor) 57d that detects the magnet 57c. A part of the movable part 57a, the spring 57b, the magnet 57c, and the Hall IC 57d are housed in a case 57e and covered by a lid part 57f shown in FIG. 1. In this way, in the sensor unit 57, a part of the movable part 57a, the spring 57b, the magnet 57c, and the Hall IC 57d are housed in the case 57e, and the sensor unit 57 is unitized.

[0041] As shown in FIG. 6, the movable part 57a of the sensor unit 57 is constantly biased in a direction away from the injection part 13 by the spring 57b in the second direction P1. As a result, when the remaining amount of the nails 78 housed in the magazine part 77 is more than the set predetermined number, the movable part 57a of the sensor unit 57 is separated from the contact part 56 of the feeder part 55 and is in a state of protruding maximally.

[0042] When the driving of the nails 78 continues in this state and the remaining amount of the nails 78 approaches the set predetermined number, the contact between the movable part 57a of the sensor unit 57 and the contact part 56 of the feeder part 55 starts. Further, when the driving continues and the remaining amount of the nails 78 reaches the set predetermined number, the Hall IC 57d detects the magnet 57c at the position of the movable part 57a shown in FIG. 5. As a result, the switch of the sensor unit 57 becomes ON, and a signal notifying that the remaining amount of the nails 78 has reached the predetermined number is transmitted from the sensor unit 57 to the controller 82 as described above, and the driving of the nails 78 stops.

[0043] Note that the movement of the feeder unit 55 toward the side close to the injection unit 13 does not stop when the switch of the sensor unit 57 is turned on, but stops when the protruding portion 55a of the feeder unit 55 abuts against the stopper portion 34c at the end of the blade guide 34. In other words, when the switch of the sensor unit 57 is turned on (the time shown in FIG. 5), the protruding portion 55a of the feeder unit 55 and the stopper portion 34c of the blade guide 34 are separated from each other, and the feeder unit 55 is in a state where it can move toward the side close to the injection unit 13. That is, the stopper portion 34c is provided at one end of the blade guide 34 so that the feeder unit 55 stops within the movable range of the movable portion 57a of the sensor unit 57.

[0044] As shown in FIG. 7, the detection unit 54 includes a switching unit capable of switching the relative distance L between the fixed portion 58 and the feeder unit 55 in the second direction P1 when the feeder unit 55 is located at a position detected by the sensor unit 57 in the process of moving toward the side close to the injection unit 13. In the first embodiment, the switching unit is a plurality of fixed portions 58, specifically, three fixed portions 58a, 58b, and 58c that can be used to fix the sensor unit 57. Then, the fixed portion 58 switches the relative distance L between the fixed portion 58 and the feeder unit 55 in the second direction P1 according to which of the three fixed portions 58a, 58b, and 58c the screw (fastening tool) 59 is fixed to. Note that, as an example, the relative distance L is the distance between the center of the fixed portion 58 (the one with the largest distance from the feeder unit 55 among the plurality of fixed portions 58. In other words, the one through which the screw 59a is inserted among the plurality of fixed portions 58) in the second direction P1 and the surface on which the contact portion 56 of the feeder unit 55 is formed.

[0045] Here, the fixing position of the sensor unit 57 in the driving machine 10a will be described in detail.

[0046] The fixed parts 58 of the sensor unit 57 are provided at a plurality of different positions in the second direction P1. In the driving machine 10a of the first embodiment, as shown in FIG. 1, two fixed parts 58a and 58c are provided at different positions in the second direction P1. Further, a fixed part 58b is provided at a position on the opposite side of the fixed part 58a of the sensor unit 57 (a position above the fixed part 58a in the vertical direction M1). That is, three fixed parts 58a, 58b, and 58c are provided on the sensor unit 57.

[0047] And in the driving machine 10a, the sensor unit 57 is fixed to the injection part 13 by using two of the three fixed parts 58a, 58b, and 58c. Specifically, as shown in FIG. 8, it is fixed to two fixing parts 38 of the blade guide 34 of the injection part 13. In detail, the sensor unit 57 shown in FIG. 1 has its fixed part 58a fixed to the fixing part 38a of the blade guide 34 in FIG. 8 by a screw (fastening tool) 59a shown in FIG. 1, and the fixed part 58b is fixed to the fixing part 38b of the blade guide 34 by a screw (fastening tool) 59b. Thus, in the driving machine 10a, regarding the fixing of the sensor unit 57, two of the three fixed parts 58a, 58b, and 58c, namely 58a and 58b, are used, and the fixed part 58c is not used.

[0048] As described above, in the driving machine 10a, the sensor unit 57 is fixed by two fixed parts 58a and 58b.

[0049] Note that the injection part 13 has a blade guide 34 arranged side by side in the front - rear direction (fourth direction) N1 orthogonal to the vertical direction (first direction) M1, and a guide plate 39. Further, as shown in FIGS. 10 and 11, an injection path 37 is formed between the blade guide 34 and the guide plate 39. And the blade guide 34 is arranged on the feeder part 55 side of the guide plate 39 in the front - rear direction (fourth direction) N1 and has a plurality of fixing parts 38 to which the fixed part 58 is fixed.

[0050] Specifically, the fixed part 58a of the sensor unit 57 is fixed to the fixed part 38a of the blade guide 34 shown in FIGS. 8 and 10 by a screw 59a. Further, the fixed part 58b of the sensor unit 57 is fixed to the fixed part 38b of the blade guide 34 shown in FIGS. 8 and 11 by a screw 59b. That is, in the driving machine 10a, as described above, the sensor unit 57 is fixed by the two fixed parts 58a and 58b, and as shown in FIG. 9, the fixed part 58c is not used.

[0051] Also, as shown in FIG. 12, the guide plate 39 is a member movable with respect to the blade guide 34 by the operation of an operator. Specifically, the guide plate 39 is a member rotatable along the opening direction Q1 so that the nail 78 can be taken out when the nail 78 clogs the injection path 37 (injection port). The guide plate 39 rotates about the hinge part 40 provided in the injection part 13 as a rotation axis. That is, the guide plate 39 is a member that can be moved as needed. Therefore, it is not preferable to fix the sensor unit 57 to a member that may be moved, and the sensor unit 57 is preferably fixed to the blade guide 34.

[0052] In order to fix the sensor unit 57 to the blade guide 34, as shown in FIG. 8, the blade guide 34 is provided with two fixed parts 38, i.e., a fixed part 38a and a fixed part 38b. In the driving machine 10a, when providing the fixed part 38a located on the lower side of the sensor unit 57, since the guide plate 39 is a movable member, it is not desired to project to the guide plate 39 side. Therefore, the fixed part 38a is provided so as to project to the feeder part 55 side of the blade guide 34. Thereby, when moving the guide plate 39, since the guide plate 39 and the blade guide 34 do not interfere with each other, the guide plate 39 can be moved smoothly.

[0053] As described above, in the angle type driver 10a, among the two fixed parts 58 on the lower side of the sensor part 57 shown in FIG. 9, the front fixed part 58a (on the blade guide 34 side) is used, and the fixed part 58a of the sensor part 57 is fixed to the fixed part 38a of the blade guide 34 by a screw 59a. Thus, in the driver 10a, as shown in FIG. 7, the relative distance L between the fixed part 58a and the feeder part 55 (more specifically, the contact part 56) in the second direction P1 is L1.

[0054] By fixing the sensor part 57 in this way using the fixed part 58 selected from among the plurality of fixed parts 58, the feeder part 55 can be detected at the set position of the remaining nail amount according to the relative distance L between the fixed part 58a and the feeder part 55.

[0055] Note that on the upper side of the sensor part 57, the fixed part 58b of the sensor part 57 is fixed to the fixed part 38b of the blade guide 34 by a screw 59b.

[0056] Next, the straight type driver 10b shown in FIGS. 13 to 19 will be described.

[0057] As shown in FIGS. 13 and 14, the sensor part 57 is also attached to the driver 10b. The sensor part 57 includes a movable part 57a that moves along the second direction P1, a spring (elastic body) 57b that biases the movable part 57a in a direction away from the injection part 13a in the second direction P1, a magnet 57c built in the movable part 57a, and a hall IC (sensor) 57d that detects the magnet 57c. And a part of the movable part 57a, the spring 57b, the magnet 57c, and the hall IC 57d are housed in a case 57e and covered by a lid part 57f shown in FIG. 14. That is, the sensor part 57 is unitized.

[0058] Next, the fixing of the sensor part 57 in the driver 10b will be described.

[0059] In the straight type driver 10b, as shown in FIG. 14, the sensor unit 57 is fixed to the injection unit 13 by two of the three fixed parts 58a, 58b, and 58c. Specifically, it is fixed to two fixing parts 38 of the blade guide 34 of the injection unit 13 shown in FIG. 15. In detail, as shown in FIG. 14, the sensor unit 57 has its fixed part 58c fixed to the fixing part 38a of the blade guide 34 in FIG. 15 by a screw 59a, and the fixed part 58b is fixed to the fixing part 38b of the blade guide 34 by a screw 59b. Thus, in the driver 10b, regarding the fixing of the sensor unit 57, two of the three fixed parts 58a, 58b, and 58c, namely 58c and 58b, are used, and the fixed part 58a is not used.

[0060] That is, in the driver 10b, the sensor unit 57 is fixed by two fixed parts 58c and 58b.

[0061] Note that in the driver 10b as well, the injection unit 13 has a blade guide 34 arranged in the front - rear direction N1 and a guide plate 39. As shown in FIGS. 17 and 18, a shooting path 37 is formed between the blade guide 34 and the guide plate 39. The blade guide 34 is arranged on the feeder unit 55 side of the guide plate 39 in the front - rear direction N1 and has a plurality of fixing parts 38 to which the fixed part 58 is fixed.

[0062] Specifically, the fixed part 58c of the sensor unit 57 is fixed to the fixing part 38a of the blade guide 34 shown in FIGS. 15 and 16 by a screw 59a. Further, the fixed part 58b of the sensor unit 57 is fixed to the fixing part 38b of the blade guide 34 by a screw 59b. That is, also in the driver 10b, as described above, the sensor unit 57 is fixed by two fixed parts 58c and 58b, and the fixed part 58a is not used.

[0063] Also, as shown in FIG. 19, in the driving machine 10b as well, the guide plate 39 is a member movable relative to the blade guide 34 by the operation of an operator. Specifically, the guide plate 39 is a member rotatable along the opening direction Q1 so that the nail 78 can be taken out when the nail 78 clogs the shooting path 37 (shooting outlet). The guide plate 39 rotates about a hinge portion 40 provided in the injection portion 13 as a rotation axis. That is, the guide plate 39 is a member that can be moved as needed. Therefore, also in the driving machine 10b, similar to the driving machine 10a, it is not preferable to fix the sensor portion 57 to a member that may move, and the sensor portion 57 is preferably fixed to the blade guide 34.

[0064] In addition, in order to fix the sensor portion 57 to the blade guide 34 also in the driving machine 10b, as shown in FIG. 15, the blade guide 34 is provided with two fixing portions 38, namely, a fixing portion 38a and a fixing portion 38b. When using the fixed portion 58 located below the sensor portion 57 in the driving machine 10b, if trying to use the fixed portion 58a, the fixing portion 38a of the blade guide 34 has to protrude significantly toward the guide plate 39 side. However, since the guide plate 39 is a movable member as described above, it is not desired to protrude toward the guide plate 39 side. Therefore, in order not to have to protrude the fixing portion 38a toward the guide plate 39 side, the fixed portion 58c of the sensor portion 57 is used to fix to the fixing portion 38a on the blade guide 34. That is, the fixed portion 58c of the sensor portion 57 is fixed to the fixing portion 38a of the blade guide 34 by a screw 59a. Thereby, when moving the guide plate 39, the guide plate 39 and the blade guide 34 do not interfere with each other, so that the guide plate 39 can be moved smoothly.

[0065] Further, the fixing portion 38a is provided on the blade guide 34, and by fixing the fixed portion 58c of the sensor portion 57 to this fixing portion 38a, the sensor portion 57 is fixed in a state of protruding toward the guide plate 39 side. As a result, the stop position of the feeder portion 55 (the position where it becomes the ON state of the switch) can be brought closer to the injection portion 13. In other words, the timing for detecting the feeder portion 55 can be made as late as possible. As a result, the number of remaining nails 78 based on the stop position of the feeder portion 55 can be reduced, and the number of nails 78 used for driving can be increased.

[0066] Also, when attempting to use the fixed portion 58a of the sensor portion 57 to fix the sensor portion 57 to the blade guide 34, as described above, the fixed portion 38a of the blade guide 34 will protrude significantly toward the guide plate 39 side. In this case, the blade guide 34 will become larger, and the driving machine 10b will also become larger, which is not preferable. Therefore, in the driving machine 10b, since the fixed portion 58c of the sensor portion 57 is used to fix to the fixed portion 38a on the blade guide 34, it is possible to avoid an increase in the size of the blade guide 34 and also avoid an increase in the size of the driving machine 10b.

[0067] As described above, in the straight type driver 10b, among the two fixed parts 58 on the lower side of the sensor part 57 shown in FIG. 16, the fixed part 58c on the rear side (feeder part 55 side) is used, and the fixed part 58c of the sensor part 57 is fixed to the fixed part 38a of the blade guide 34 by a screw 59a. Thus, in the driver 10b, as shown in FIG. 14, the relative distance L between the fixed part 58c and the feeder part 55 (more specifically, the contact part 56) in the second direction P1 becomes L2. Also in the driver 10b like this, by fixing the sensor part 57 using the fixed part 58 selected from among the plurality of fixed parts 58, the feeder part 55 can be detected at the set position of the remaining nail amount according to the relative distance L between the fixed part 58a and the feeder part 55. Further, the relative distance L2 of the driver 10b is smaller than the relative distance L1 of the driver 10a (L2 < L1). Thereby, the driver 10b can bring the stop position (the position where it becomes the ON state of the switch) of the feeder part 55 closer to the injection part 13 compared to the driver 10a, and can further reduce the number of remaining nails 78 based on the stop position of the feeder part 55.

[0068] Note that, above the sensor part 57 of the driver 10b, similar to the driver 10a, the fixed part 58b of the sensor part 57 is fixed to the fixed part 38b of the blade guide 34 by a screw 59b.

[0069] The working machine system 90 of the first embodiment includes a driver (first working machine) 10a shown in FIGS. 1 and 5 to 12, a driver (second working machine) 10b shown in FIGS. 4 and 13 to 19, and a detection unit 54. That is, the driver 10a includes a magazine part (first magazine part) 77a that houses nails (first fasteners) 78a, an injection part (first injection part) 13a to which the nails 78a are supplied from the magazine part 77a, and a striking part (first striking part) 12a that strikes the nails 78a supplied to the injection part 13a in the vertical direction M1. Note that the injection part 13a is provided with a first blade guide 34a and a first guide plate 39a.

[0070] On one hand, the driving machine 10b includes a magazine section (second magazine section) 77b that houses nails (second fasteners) 78b, an injection section (second injection section) 13b from which the nails 78b are supplied from the magazine section 77b, and a striking section (second striking section) 12b that strikes the nails 78b supplied to the injection section 13b in the vertical direction M1. The injection section 13b is provided with a second blade guide 34b and a second guide plate 39b.

[0071] In addition, the detection unit 54 is alternatively attached to either the driving machine 10a or the driving machine 10b and is capable of detecting the nails 78a housed in the magazine section 77a or the nails 78b housed in the magazine section 77b. The detection unit 54 is also a nail detection unit that can be attached to either the driving machine 10a or the driving machine 10b.

[0072] That is, the work machine system 90 is a system that unitizes a sensor for detecting the remaining amount of the nails 78 together with the feeder section 55 and includes a detection unit 54 that can be attached to any of a plurality of work machines such as the driving machine 10a and the driving machine 10b.

[0073] According to the detection unit 54 and the work machine system 90 of the first embodiment, the sensor section 57 for detecting the remaining amount of the nails 78 and the feeder section 55 are combined and unitized, and by providing a plurality of fixed parts 58 in the sensor section 57, when fixing the unitized sensor section 57 to the driving machine 10a or the driving machine 10b, the fixed part 58 can be selected from the plurality of fixed parts 58 and used for fixing. That is, by providing the unused fixed parts 58, it is possible to attach the unitized sensor section 57 to both the driving machine 10a and the driving machine 10b while suppressing the enlargement of the driving machine 10a and the driving machine 10b or the complication of the structure of the driving machine 10a and the driving machine 10b.

[0074] As a result, the convenience of work machines such as the driving machine 10a and the driving machine 10b can be improved.

[0075] In addition, since the sensor unit 57 and the feeder unit 55 are combined and unitized to enable attachment to a plurality of working machines, it is possible to reduce the manufacturing cost of the working machines.

[0076] (Embodiment 2) In the second embodiment, in the detection unit 54 and the working machine system 90, when attaching the unitized sensor unit 57 and feeder unit 55 to the driving machine 10a or the driving machine 10b, by giving the feeder unit 55 alternative shapes, it becomes possible to attach the unitized sensor unit 57 and feeder unit 55 to a plurality of working machines such as the driving machine 10a and the driving machine 10b. That is, instead of providing a plurality of fixed parts 58 on the sensor unit 57 as in the first embodiment, the feeder unit 55 is given alternative shapes, thereby enabling the unitized sensor unit 57 and feeder unit 55 to be attached to the driving machine 10a or the driving machine 10b.

[0077] The internal structures of the driving machine 10a of the second embodiment shown in FIG. 21 and the driving machine 10b of the second embodiment shown in FIG. 22 are the same as the internal structures of the driving machine 10a and the driving machine 10b of the first embodiment shown in FIGS. 1 to 4, so the overlapping description is omitted. Further, regarding the internal structure of the sensor unit 57 attached to the driving machine 10a or the driving machine 10b, since it is the same as the internal structure of the sensor unit 57 shown in FIGS. 5 and 6, the overlapping description is omitted.

[0078] The differences between the driving machine 10a and the driving machine 10b of the second embodiment and the driving machine 10a and the driving machine 10b of the first embodiment will be described.

[0079] First, as shown in FIGS. 21 and 22, one fixed part 58 is provided on each side of the sensor unit 57 as the fixed part 58 of the sensor unit 57. That is, instead of providing a plurality of fixed parts 58 on one side of the sensor unit 57, one fixed part 58 is provided on one side of the sensor unit 57, and another fixed part 58 is provided on the other side of the sensor unit 57.

[0080] Specifically, in both the driving machine 10a shown in FIG. 21 and the driving machine 10b shown in FIG. 22, one fixed part 58a is provided at a position below the sensor part 57, and this fixed part 58a is fixed to the blade guide 34 by a screw 59a. On the other hand, one fixed part 58b is provided at a position above the sensor part 57, and this fixed part 58b is fixed to one end of the blade guide 34 by a screw 59b.

[0081] Therefore, in both the driving machine 10a and the driving machine 10b, the same two fixed parts 58 (fixed parts 58a, 58b) are used, and no fixed part 58 that is not used by the fixed part 58 of the sensor part 57 is provided. That is, in the driving machine 10a and the driving machine 10b, one of the same fixed parts 58 provided on both the left and right sides of the sensor part 57 is used, and the sensor part 57 is screwed and fixed to the blade guide 34 at two locations, one on each side.

[0082] Thus, also in the second embodiment, since the guide plate 39 is not used for fixing the sensor part 57, the guide plate 39 can be moved. That is, when rotating the guide plate 39, the guide plate 39 and the blade guide 34 do not interfere with each other, so the guide plate 39 can be rotated smoothly.

[0083] In the second embodiment, the shape of the feeder part 55 shown in FIG. 20 is different from the shape of the feeder part 55 shown in FIG. 1 of the first embodiment. That is, the feeder part 55 of the second embodiment shown in FIG. 20 is provided in a plurality of different positions in the third direction S1 orthogonal to the second direction P1, and has a plurality of contact parts 56 (56a, 56b) that selectively contact the sensor part 57 in the process of the feeder part 55 shown in FIGS. 21 and 22 moving toward the side close to the injection part 13. That is, as shown in FIG. 20, the feeder part 55 of the second embodiment has, as the contact part 56, at different positions in the third direction S1 orthogonal to the second direction P1 The contact portions 56a and 56b with different heights are provided. In the feeder portion 55 shown in FIG. 20, the contact portion 56a is higher in height than the contact portion 56b and is provided at the end portion.

[0084] And, the contact portion 56a and the contact portion 56b of the second embodiment are switching portions that switch the relative distance L between the fixed portion 58 and the feeder portion 55 in the second direction P1 according to whether the sensor portion 57 contacts the contact portion 56a or the contact portion 56b in the driving machine 10a shown in FIG. 21 and the driving machine 10b shown in FIG. 22. In the driving machine 10a and the driving machine 10b of the second embodiment, the sensor portion 57 is fixed using the same two fixed portions 58 (fixed portions 58a, 58b). At that time, as shown in FIG. 21, in the driving machine 10a, the sensor portion 57 is attached so that the movable portion 57a of the sensor portion 57 contacts the contact portion 56a having a higher height of the feeder portion 55. On the other hand, as shown in FIG. 22, in the driving machine 10b, the sensor portion 57 is attached so that the movable portion 57a of the sensor portion 57 contacts the contact portion 56b having a lower height of the feeder portion 55.

[0085] Therefore, the relative distance L between the fixed portion 58 (more specifically, the fixed portion 58a) and the feeder portion 55 (more specifically, the contact portion 56a) is shorter in the driving machine 10b than in the driving machine 10a. By giving the feeder portion 55 such selectivity in shape, the feeder portion 55 can be detected at the set position of the remaining nail amount according to the relative distance L between the fixed portion 58a and the feeder portion 55. Also, in the second embodiment, the driving machine 10b can bring the stop position (the position where the switch is turned on) of the feeder portion 55 closer to the injection portion 13 than the driving machine 10a, and the number of remaining nails 78 based on the stop position of the feeder portion 55 can be reduced.

[0086] According to the detection unit 54 and the work machine system 90 of the second embodiment, a sensor unit 57 for detecting the remaining amount of the nails 78 and a feeder unit 55 are combined and unitized, and by providing contact portions 56a and 56b with different positions and heights at the contact portion 56 of the feeder unit 55, the same sensor unit 57 and feeder unit 55 unitized can be attached to the driving machine 10a or the driving machine 10b.

[0087] As a result, also in the driving machines 10a and 10b of the second embodiment, while suppressing the driving machines 10a and 10b from becoming larger or the structures of the driving machines 10a and 10b from becoming more complex, the sensor unit 57 and the feeder unit 55 can be attached to both the driving machine 10a and the driving machine 10b.

[0088] As a result, also in the second embodiment, the convenience of work machines such as the driving machine 10a and the driving machine 10b can be improved.

[0089] In addition, since the sensor unit 57 and the feeder unit 55 are combined and unitized and can be attached to a plurality of work machines, it is possible to reduce the manufacturing cost of the work machines.

[0090] The present invention is not limited to the above embodiments, and various modifications can be made without departing from the gist thereof. For example, in the above first and second embodiments, the case where the sensor unit 57 is fixed to the blade guide 34 has been described, but the sensor unit 57 may be fixed to the magazine unit 77 using screws.

[0091] In addition, in the second embodiment described above, the case where the contact portions 56a and 56b having different positions and heights are provided on the contact portion 56 of the feeder portion 55 as the switching portion has been described. However, as the switching portion provided on the feeder portion 55, a detachable cap that changes the height of the contact portion 56 may be attached to the contact portion 56 of the feeder portion 55. That is, the height of the contact portion 56 may be switched between the case where the cap is attached and the case where the cap is removed. Thereby, the same effect as the case where the contact portions 56a and 56b having different heights are provided on the contact portion 56 of the feeder portion 55 can be obtained.

[0092] In addition, the number of the fixed portions 58 provided on one side of the sensor portion 57 may be three or more. Further, the contact portions 56 having different heights provided on the feeder portion 55 may be three or more types.

[0093] In addition, the sensor portion (detection portion) 57 does not necessarily directly contact the feeder portion (biasing portion) 55. For example, a link member (detected portion) that moves as the feeder portion 55 moves or as the nail 78 is supplied is provided between the sensor portion (detection portion) 57 and the feeder portion (biasing portion) 55, and the sensor portion 57 contacts this link member to detect the link member, so that the remaining amount of the nails 78 in the magazine portion 77 is detected. It is good also as a structure to do.
