[0035] In addition, the combination of features and processes disclosed in the following detailed description is not necessary for implementing the present invention in the broadest sense, but is recorded only for the purpose of specifically illustrating the representative specific examples of the present invention. Moreover, when providing additional and useful embodiments of the present invention, the various features of the representative specific examples described above and below and the various features described in the independent claims and dependent claims do not necessarily have to be combined as in the specific examples described herein or in the order in which they are listed.

[0036] All features described in this specification and / or claims are intended to be disclosed separately and independently of each other, as limitations on the disclosure of the original application and the specific matters described in the claims, independent of the structures of the features described in the embodiments and / or claims. Furthermore, the descriptions related to all numerical ranges and groups or groups have the intention of disclosing the structures among them as limitations on the disclosure of the original application and the specific matters described in the claims.

[0037] The reinforcing bar tying machine disclosed in this specification includes: a twisting motor that operates a twisting member that twists steel wires around reinforcing bars; a main body casing that accommodates the twisting motor; and a first lighting member that is held in the main body casing and irradiates light toward the reinforcing bars.

[0038] In one or more embodiments, the first lighting member may include a transmission portion that transmits light from the inside of the first lighting member to the outside of the first lighting member. The width of the transmission portion may be greater than the diameter of the reinforcing bar.

[0039] According to the above structure, the width of the light passing through the transmission part is larger than the diameter of the reinforcing bar. Therefore, the entire reinforcing bar is illuminated, thereby making it easier to visually identify the reinforcing bar.

[0040] In one or more embodiments, the reinforcing bar tying machine may further include a guide member for winding the steel wire around the reinforcing bar. The main body housing may include a guide member holding portion for holding the guide member. The first lighting member may be disposed on the guide member holding portion.

[0041] According to the above configuration, when the reinforcing bar is bundled using the reinforcing bar bundling machine, the guide member is arranged near the reinforcing bar. Therefore, the first lighting member is arranged near the reinforcing bar. Thus, the reinforcing bar can be visually recognized more easily by the light of the first lighting member.

[0042] In one or more embodiments, the reinforcing bar tying machine may further include a second lighting unit that is held in the main body casing and irradiates light toward the reinforcing bars.

[0043] According to the above-mentioned structure, compared with the structure using one lighting member, the reinforcing bar can be visually recognized more easily.

[0044] In one or more embodiments, the reinforcing bar tying machine may further include a guide member for winding the steel wire around the reinforcing bar. The main body housing may include a guide member holding portion for holding the guide member. The first lighting member and the second lighting member may be disposed on the guide member holding portion.

[0045] According to the above structure, when the reinforcing bar is bundled using the reinforcing bar bundling machine, the guide member is arranged near the reinforcing bar. Therefore, the first lighting member and the second lighting member are arranged near the reinforcing bar. Thus, the reinforcing bar can be visually recognized more easily by the light of the first lighting member and the light of the second lighting member.

[0046] In one or more embodiments, the twisting motor may rotate around a central axis extending in the front-rear direction. When the reinforcing bar tying machine is viewed in the front-rear direction, the guide member may be arranged between the first lighting member and the second lighting member in a left-right direction orthogonal to the front-rear direction.

[0047] According to the above-mentioned structure, when the steel bar tying machine is used to tie steel bars, the light of the first lighting component and the light of the second lighting component illuminate the steel bars. When the steel bars are illuminated by the light of the first lighting component, a shadow is formed on the wall surface located on the rear side of the steel bars, and on the other hand, the light of the second lighting component illuminates the shadow. In addition, when the steel bars are illuminated by the light of the second lighting component, a shadow is formed on the wall surface located on the rear side of the steel bars, and on the other hand, the light of the first lighting component illuminates the shadow. As a result, the shadow on the wall surface located on the rear side of the steel bars can be made less noticeable. In addition, even if the shadow on the wall surface located on the rear side of the steel bars moves when the steel bar tying machine is moved, it is possible to prevent the user from being attracted by the shadow.

[0048] In one or more embodiments, when the reinforcing bar tying machine is viewed in the front-rear direction, the twisted member may be arranged between the first illuminating member and the second illuminating member in the left-right direction orthogonal to the front-rear direction.

[0049] According to the above configuration, when the reinforcing bars are bundled, the shadow on the wall surface located on the rear side of the reinforcing bars can be made less noticeable.

[0050] In one or more embodiments, the distance between the first lighting member and the second lighting member may be greater than the diameter of the reinforcing bar.

[0051] According to the above configuration, when the reinforcing bars are bundled, the shadow on the wall surface located on the rear side of the reinforcing bars can be made less noticeable.

[0052] In one or more embodiments, the luminous flux of the light emitted by the first lighting member may be greater than or equal to 1 lumen and less than or equal to 10,000 lumen.

[0053] According to the above configuration, the reinforcing bar can be more easily visually recognized by the light of the first lighting means.

[0054] In one or more embodiments, the illuminance of the light emitted by the first lighting member may be 70 lux or more and 3000 lux or less at a position 150 mm away from the first lighting member in the irradiation direction of the light.

[0055] According to the above configuration, the reinforcing bar can be more easily visually recognized by the light of the first lighting means.

[0056] In one or more embodiments, the first lighting member may include a light emitting unit that emits light and a diffusion unit that diffuses the light emitted by the light emitting unit.

[0057] According to the above configuration, compared with a configuration in which the first lighting member does not include a diffusion portion, the irradiation range of the light of the first lighting member can be expanded.

[0058] In one or more embodiments, the reinforcing bar binding machine may further include: a control unit that activates the twisting motor; and a wire that connects the first lighting member and the control unit. Alternatively, the main body housing may include a handle that is held by a user when using the reinforcing bar binding machine, and the wire may pass through the handle.

[0059] According to the above-mentioned structure, the space in the handle part can be effectively utilized.

[0060] In one or more embodiments, the reinforcing bar tying machine may further include: a feed motor that operates a feed member that feeds out the steel wire; a control unit that operates the twisting motor and the feed motor; and a wire that connects the first lighting member and the control unit. Alternatively, the main body housing may include a feed motor storage portion that stores the feed motor, and the wire passes through the inside of the feed motor storage portion.

[0061] According to the above-mentioned structure, the space in the feed motor housing portion can be effectively utilized.

[0062] In one or more embodiments, the reinforcing bar tying machine may further include a control unit that can operate the first lighting component and the twisting motor to perform a tying process of the steel wires around the tying reinforcing bars. The control unit may also light the first lighting component before performing the tying process.

[0063] According to the above configuration, when reinforcing bars are bundled, the reinforcing bars can be easily visually recognized.

[0064] (First embodiment)

[0065] like Figure 1 As shown, the steel bar tying machine 2 uses a steel wire W to tie a plurality of steel bars R. In the steel bar tying machine 2, according to the diameter D1 (refer to Figure 5 ), using steel wires W of various diameters (e.g., diameters of 0.5 mm to 2.5 mm). For example, when bundling thin-diameter steel bars R with a diameter D1 of 16 mm or less (e.g., diameter 16 mm), steel wires W with a diameter of 1.6 mm or less (e.g., 0.8 mm) are used, and when bundling thick-diameter steel bars R with a diameter D1 greater than 16 mm (e.g., diameters of 25 mm or 32 mm), steel wires W with a diameter of 1.6 mm or more (e.g., 2.0 mm) are used. Next, the stranding unit 56 (see Figure 2 ) is called the front-to-back direction, the direction perpendicular to the front-to-back direction is called the up-down direction, and the direction perpendicular to the front-to-back direction and the up-down direction is called the left-right direction.

[0066] The reinforcing bar binding machine 2 includes a main body case 4 and a battery pack BP. The main body case 4 includes a right side case 6 defining the outer shape of the right half of the main body case 4, a left side case 8 defining the outer shape of the left half of the main body case 4, and a reel cover 10 rotatably mounted on the front lower portion of the left side case 8.

[0067] The main body case 4 includes a guide member holding portion 14, a twisting motor housing portion 16, a handle portion 18, a control unit housing portion 20, a feed motor housing portion 22, and a reel housing portion 24. The guide member holding portion 14, the twisting motor housing portion 16, the handle portion 18, the control unit housing portion 20, and the feed motor housing portion 22 are formed by the right case 6 and the left case 8. The reel housing portion 24 is formed by the right case 6, the left case 8, and the reel cover 10.

[0068] like Figure 2 As shown, the guide member holding portion 14 extends in the front-rear direction. The twisting motor storage portion 16 is arranged on the rear side of the guide member holding portion 14. The handle portion 18 is arranged on the lower side of the twisting motor storage portion 16. The handle portion 18 is for the user to hold. The longitudinal direction of the handle portion 18 is slightly inclined with respect to the up-down direction. The rebar tying machine 2 includes a trigger 26, and the trigger 26 is installed on the upper front surface of the handle portion 18 in a manner that can be pulled in. When the trigger 26 is pulled in, the trigger detection switch 27 in the handle portion 18 is pressed in.

[0069] The control unit storage section 20 is arranged at the lower side of the handle section 18. The battery pack BP is detachably mounted at the lower end of the control unit storage section 20. The battery pack BP is mounted on the control unit storage section 20 by sliding the battery pack BP toward the front lower side relative to the control unit storage section 20, and is removed from the control unit storage section 20 by sliding the battery pack BP toward the rear upper side relative to the control unit storage section 20. The battery pack BP includes a secondary battery such as a lithium ion battery, for example.

[0070] The feed motor housing portion 22 is disposed on the lower side of the guide member holding portion 14. The feed motor housing portion 22 is disposed on the front side of the handle portion 18 so as to be separated from the handle portion 18.

[0071] The reel storage section 24 is arranged on the lower side of the feed motor storage section 22. Figure 2 In the figure, the reel storage section 24 is shown by a dotted line. The reel storage section 24 is connected to the front end of the control unit storage section 20 via a connection portion 28. Figure 3 As shown, the reel storage section 24 can store a reel 30. The reel 30 includes a wire W and a reel 32 around which the wire W is wound. The reel 30 is rotatably held in the reel storage section 24. The reel 30 can be attached to and detached from the reel storage section 24 when the reel cover 10 is opened relative to the left housing 8.

[0072] like Figure 1 As shown, the reinforcing bar tying machine 2 further includes a main power switch 36, a display unit 38, a mode switching switch 40, a tying force increase switch 42, and a tying force reduction switch 44. The main power switch 36, the display unit 38, the mode switching switch 40, the tying force increase switch 42, and the tying force reduction switch 44 are arranged on the rear surface of the feeding motor storage unit 22. The main power switch 36 receives an operation of the user to switch the on state and the off state of the reinforcing bar tying machine 2. The reinforcing bar tying machine 2 can be operated in the on state. The reinforcing bar tying machine 2 cannot be operated in the off state. The display unit 38 displays information related to the reinforcing bar tying machine 2. The display unit 38 is for visual recognition by the user.

[0073] The mode switching switch 40 switches the mode of the reinforcing bar tying machine 2 between the single shot mode and the continuous shot mode. When the reinforcing bar tying machine 2 is in the single shot mode, each time the trigger 26 is pulled in, the reinforcing bar tying machine 2 performs an action of tying a plurality of reinforcing bars R with the steel wire W. When the reinforcing bar tying machine 2 is in the continuous shot mode, each time the contact member 46 at the front end of the main body 4 is pressed in by the reinforcing bar R while the trigger 26 is maintained in the pulled in state, the reinforcing bar tying machine 2 performs an action of tying a plurality of reinforcing bars R with the steel wire W. In addition, the pressing of the contact member 46 is detected by the detection switch 48 (see Figure 2 ) detection.

[0074] The binding force increase switch 42 increases the setting value of the binding force of the steel wire W by the reinforcing bar binding machine 2. The binding force reduction switch 44 reduces the setting value of the binding force of the steel wire W by the reinforcing bar binding machine 2. When the binding force increase switch 42 is operated, the setting value of the binding force of the steel wire W is increased by one level, and when the binding force reduction switch 44 is operated, the setting value of the binding force of the steel wire W is reduced by one level. The binding force of the steel wire W corresponds to the force of twisting the steel wires W.

[0075] like Figure 2 As shown, the reinforcing bar tying machine 2 further includes a feeding unit 50 , a guiding unit 52 , a cutting unit 54 , a twisting unit 56 , and a control unit 58 .

[0076] The feeding unit 50 is accommodated in the feeding motor accommodation portion 22. The feeding unit 50 includes a feeding motor 62 and a feeding roller 64. The feeding motor 62 is, for example, a brushless motor. The feeding motor 62 rotates by the power supplied from the battery pack BP. The feeding roller 64 is connected to the feeding motor 62 via a reducer (not shown). The feeding roller 64 corresponds to a feeding member. When the feeding motor 62 rotates, the feeding roller 64 rotates. The feeding roller 64 pulls the steel wire W out of the reel 32 by rotating in the forward direction and sends it to the upper front side toward the guide unit 52. In addition, the feeding roller 64 pulls the steel wire W back toward the reel 32 by rotating in the reverse direction.

[0077] The guide unit 52 includes an upper curling guide member 68 and a lower curling guide member 70. The upper curling guide member 68 and the lower curling guide member 70 are held at the front end of the guide member holding portion 14. The upper curling guide member 68 and the lower curling guide member 70 extend forward from the front end of the guide member holding portion 14. The reinforcing bars R are arranged between the upper curling guide member 68 and the lower curling guide member 70 when bundling. The steel wire W fed from the feed roller 64 is first guided by the upper curling guide member 68 and passes through the upper curling guide member 68 from the rear to the front. While the steel wire W passes through the upper curling guide member 68, the upper curling guide member 68 gives the steel wire W a downward winding tendency. After passing through the upper curling guide member 68, the steel wire W is guided by the lower curling guide member 70 and passes through the lower curling guide member 70 from the front to the rear. Thereafter, the steel wire W moves to the rear and upper side. Thus, the steel wire W is wound around the steel bar R.

[0078] The cutting unit 54 is accommodated in the guide member holding portion 14. The cutting unit 54 is arranged below the twisting unit 56. The cutting unit 54 includes a cutter (not shown) for cutting the wire W fed from the feeding unit 50 to the guide unit 52. The wire W is cut by rotating the cutter.

[0079] The twisting unit 56 is arranged across the guide member holding portion 14 and the twisting motor storage portion 16. The twisting unit 56 includes a twisting motor 74, a sleeve unit 76, and a holding fixture 78. The twisting motor 74 is stored in the twisting motor storage portion 16. The twisting motor 74 is, for example, a brushless motor. The twisting motor 74 rotates around the central axis AX by the power supplied from the battery pack BP. The central axis AX extends in the front-rear direction.

[0080] The sleeve unit 76 and the holding fixture 78 are accommodated in the guide member holding portion 14. When the twisting motor 74 rotates, the sleeve unit 76 moves in the front-back direction or rotates around the central axis AX. The holding fixture 78 is located in the front part of the twisting unit 56. The holding fixture 78 corresponds to the twisting member. When the twisting motor 74 rotates forward and the sleeve unit 76 moves forward, the holding fixture 78 holds both ends of the steel wire W around the reinforcing bar R. If the twisting motor 74 further rotates forward from this state and the sleeve unit 76 rotates forward, the holding fixture 78 rotates integrally with the sleeve unit 76. Thus, the holding fixture 78 twists the steel wire W. As a result, the reinforcing bar R is bundled using the steel wire W. When the twisting motor 74 rotates reversely from this state and the sleeve unit 76 rotates reversely, the steel wire W is released from the holding fixture 78. If the twisting motor 74 further rotates reversely, the sleeve unit 76 moves backward.

[0081] The control unit 58 is stored in the control unit storage portion 20. The control unit 58 includes a control substrate 82 having an MCU (not shown) and a switch element (not shown). The control unit 58 is electrically connected to the trigger detection switch 27, the main power switch 36, the display unit 38, the mode switching switch 40, the binding force increase switch 42, the binding force decrease switch 44, the detection switch 48, the feed motor 62, the twisting motor 74, and the battery pack BP. When the trigger 26 is pulled in by the user when the reinforcing bar binding machine 2 is in the on state, or when the trigger 26 is pulled in by the user and the contact member 46 is pressed in, the control unit 58 operates the feed motor 62 and the twisting motor 74 to perform the binding process of binding the reinforcing bars R using the steel wire W.

[0082] Specifically, first, the control unit 58 rotates the feed motor 62 in the forward direction, and rotates the feed roller 64 in the forward direction. As a result, the steel wire W is fed out, and the steel wire W is guided by the upper curling guide member 68 and the lower curling guide member 70, and is wound around the reinforcing bar R. Next, the control unit 58 rotates the twisting motor 74 in the forward direction, and moves the sleeve unit 76 forward. As a result, the front end of the steel wire W is gripped by the gripping fixture 78. Next, the control unit 58 rotates the feed motor 62 in the reverse direction, and rotates the feed roller 64 in the reverse direction. The steel wire W is pulled back, and the steel wire W is reduced in diameter and contacts the reinforcing bar R. Next, the control unit 58 rotates the twisting motor 74 in the forward direction, and moves the sleeve unit 76 forward. As a result, the steel wire W is gripped by the gripping fixture 78 between the upper curling guide member 68 and the cutting unit 54. Next, the control unit 58 further rotates the twisting motor 74 in the forward direction, and moves the sleeve unit 76 further forward. The cutting unit 54 is operated by the twisting unit 56, so that the steel wire W is cut by the cutting unit 54. Next, the control unit 58 causes the twisting motor 74 to further rotate in the positive direction, so that the sleeve unit 76 rotates in the positive direction. The steel wire W is twisted by rotating the holding fixture 78 around the central axis AX. Next, the control unit 58 causes the twisting motor 74 to rotate in the reverse direction, so that the sleeve unit 76 rotates in the reverse direction. Thus, the steel wire W is released from the holding fixture 78. Finally, the control unit 58 causes the twisting motor 74 to rotate in the reverse direction, so that the sleeve unit 76 moves backward. Thus, the twisting unit 56 returns to the initial position.

[0083] like Figure 3As shown, the reinforcing bar binding machine 2 includes a first lighting member 100 and a second lighting member 102. The first lighting member 100 and the second lighting member 102 emit light. The structure of the first lighting member 100 is substantially the same as that of the second lighting member 102. Therefore, in the following description, the first lighting member 100 and the second lighting member 102 are sometimes described using a common name "lighting member 104". The luminous flux of the light emitted by the lighting member 104 is 1 lumen or more and 10,000 lumens or less. The luminous flux of the light emitted by the lighting member 104 may be 1 lumen or more and 1,500 lumens or less, 1 lumen or more and 1,000 lumens or less, 3 lumens or more and 500 lumens or less, or 5 lumens or more and 300 lumens or less. In addition, the illuminance of the light emitted by the lighting member 104 is 70 lux or more and 3,000 lux or less at a position 150 mm away from the lighting member 104 in the irradiation direction of the light (for example, in front). The illuminance of the light emitted by the lighting component 104 at a position 150 mm away from the lighting component 104 in the irradiation direction of the light may be greater than 70 lux and less than 2500 lux, greater than 100 lux and less than 2500 lux, or greater than 100 lux and less than 2000 lux.

[0084] like Figure 4 As shown, the lighting component 104 includes a lens 108 , a substrate 110 , an adhesive 112 , and a plurality of (four in this embodiment) chip LEDs 114 .

[0085] The lens 108 defines the outer shape of the lighting component 104. The lens 108 is configured to transmit light. Figure 4 In the figure, the direction of light is shown by arrow lines. The lens 108 corresponds to the transmission part. In addition, the lens 108 is configured to diffuse light. The lens 108 corresponds to the diffusion part. The lens 108 is formed of, for example, acrylic resin, polycarbonate, polyamide, or ABS.

[0086] The lens 108 includes a first storage portion 118 and a second storage portion 120. The first storage portion 118 has a first storage space 122 therein. The second storage portion 120 has a second storage space 124 therein. The second storage portion 120 is disposed at the rear side of the first storage portion 118. The width of the second storage portion 120 in the vertical direction is greater than the width of the first storage portion 118 in the vertical direction. Therefore, a step portion 126 is formed between the first storage portion 118 and the second storage portion 120 inside the lens 108.

[0087] The base plate 110 is disposed in the second storage space 124. The base plate 110 has a plate shape. The first surface 110a of the base plate 110 abuts against the step portion 126 from the rear side. The reinforcing bar binding machine 2 further includes a wire 128, and the wire 128 is connected to the second surface 110b of the base plate 110. The second surface 110b is a surface on the side opposite to the first surface 110a. Figure 2 As shown, the wire 128 passes through the guide member holding portion 14, the twisted motor storage portion 16, the handle portion 18, and the control unit storage portion 20 in sequence. The wire 128 is connected to the control substrate 82 in the control unit storage portion 20. Thus, the substrate 110 (see Figure 4 ) is electrically connected to the control substrate 82.

[0088] like Figure 4 As shown, the adhesive 112 is disposed in the second storage space 124. The adhesive 112 abuts against the second surface 110b of the substrate 110. In a state where the first surface 110a of the substrate 110 abuts against the step portion 126, the adhesive 112 is injected into the second storage space 124 and cured, so that the substrate 110 is fixed to the lens 108, and the wire 128 is firmly fixed to the substrate 110.

[0089] The chip LED 114 is a surface mounted device (SMD) type LED. A plurality of chip LEDs 114 are mounted on the first surface 110a of the substrate 110. The plurality of chip LEDs 114 are arranged in the first storage space 122. The chip LEDs 114 are controlled by the control unit 58 (see Figure 2 ) to operate. The chip LED114 is connected to the battery pack BP (refer to Figure 1 ) of electricity and emits light.

[0090] The light emitted from the chip LED 114 reaches the lens 108 and then passes through the lens 108. While passing through the lens 108, the light is diffused by the lens 108. Thus, the diffused light is emitted from the lighting member 104.

[0091] like Figure 3 As shown, the first lighting member 100 and the second lighting member 102 are held by the main body housing 4. The first lighting member 100 and the second lighting member 102 are arranged on the guide member holding portion 14. The first lighting member 100 and the second lighting member 102 are separated in the left-right direction. The position of the first lighting member 100 in the up-down direction is substantially the same as the position of the second lighting member 102 in the up-down direction. The first lighting member 100 and the second lighting member 102 face forward. Figure 2 As shown, the first lighting component 100 and the second lighting component 102 (see Figure 3) is arranged above the handle 18, the trigger 26 and the feed motor housing 22. The first lighting member 100 and the second lighting member 102 are arranged in front of the trigger 26, the feed unit 50, the cutting unit 54 and the holding fixture 78. Figure 5 As shown, when the reinforcing bar tying machine 2 is viewed from the rear, the first lighting member 100 and the second lighting member 102 are arranged below the upper curling guide member 68 and above the lower curling guide member 70. In the vertical direction, the first lighting member 100 and the second lighting member 102 are arranged between the upper curling guide member 68 and the lower curling guide member 70. The center of the first lighting member 100 in the vertical direction and the center of the second lighting member 102 in the vertical direction are arranged above the central axis AX.

[0092] The first lighting member 100 is arranged on the right side of the upper curling guide member 68, the lower curling guide member 70, the holding fixture 78, and the center axis AX. The second lighting member 102 is arranged on the left side of the upper curling guide member 68, the lower curling guide member 70, the holding fixture 78, and the center axis AX. In the left-right direction, the upper curling guide member 68, the lower curling guide member 70, the holding fixture 78, and the center axis AX are arranged between the first lighting member 100 and the second lighting member 102. Therefore, when the reinforcing bars R are arranged between the upper curling guide member 68 and the lower curling guide member 70 when bundling, a part of the reinforcing bars R is arranged between the first lighting member 100 and the second lighting member 102, and the intersection of the two reinforcing bars R is arranged between the first lighting member 100 and the second lighting member 102.

[0093] The distance L1 between the first lighting member 100 and the second lighting member 102 in the left-right direction is greater than the diameter D1 of the steel bar R. The distance L1 is greater than 1.5 times and less than 10 times the diameter D1. In addition, the distance L1 may be greater than 2 times and less than 5 times the diameter D1. The width W1 of the first lighting member 100 in the up-down direction and the width W2 of the second lighting member 102 in the up-down direction are respectively greater than the diameter D1 of the steel bar R. The width W1 and the width W2 are each greater than 1.5 times and less than 10 times the diameter D1. In addition, the width W1 and the width W2 may each be greater than 2 times and less than 5 times the diameter D1. The width W1 is substantially the same as the width W2. The width W3 of the first lighting member 100 in the left-right direction and the width W4 of the second lighting member 102 in the left-right direction are respectively greater than the diameter D1 of the steel bar R. The width W1 is greater than the width W3, and the width W2 is greater than the width W4. In a modified example, width W1 may be less than width W3, and width W2 may be less than width W4. In addition, width W1 and width W2 are substantially the same as the width of lens 108 in the vertical direction, and width W3 and width W4 are substantially the same as the width of lens 108 in the horizontal direction.

[0094] like Figure 6 As shown in FIG. 1 , when the first lighting member 100 and the second lighting member 102 emit light, the reinforcing bar R is illuminated by the light. Figure 6 and Figure 7 In the figure, the dotted line shows the irradiation range of the light emitted by the first lighting member 100 and the second lighting member 102. At this time, due to the light emitted by the first lighting member 100, a shadow S1 extending in the left-right direction is formed on the wall surface located on the rear side of the reinforcing bar R, and due to the light emitted by the second lighting member 102, a shadow S2 extending in the left-right direction is formed on the wall surface located on the rear side of the reinforcing bar R. In this embodiment, since the distance L1 between the first lighting member 100 and the second lighting member 102 is greater than the diameter D1 of the reinforcing bar R, the light emitted by the second lighting member 102 irradiates the shadow S1, and the light emitted by the first lighting member 100 irradiates the shadow S2. As a result, the shadows S1 and S2 are not noticeable. In addition, even if the shadows S1 and S2 are moved by moving the reinforcing bar tying machine 2, it is possible to prevent the user from being attracted by the shadows S1 and S2.

[0095] In addition, if Figure 7As shown, when the steel bar R is irradiated with light, a shadow S3 extending in the vertical direction is formed on the wall surface located behind the steel bar R due to the light emitted by the first lighting member 100 and the light emitted by the second lighting member 102. In this embodiment, the width W1 of the first lighting member 100 in the vertical direction and the width W2 of the second lighting member 102 in the vertical direction are respectively larger than the diameter D1 of the steel bar R, so a part of the light emitted by the first lighting member 100 (for example, the light indicated by the arrow lines A1 and A2) and a part of the light emitted by the second lighting member 102 (for example, the light indicated by the arrow lines A1 and A2) illuminate the shadow S3. As a result, the shadow S3 is not obvious. In addition, even if the shadow S3 moves due to the movement of the steel bar tying machine 2, it is possible to prevent the user from being attracted by the shadow S3.

[0096] Next, the operations performed by the control unit 58 are described. Figure 8 Processing shown.

[0097] In S2, when the reinforcing bar binding machine 2 is in the off state, the control unit 58 determines whether the main power switch 36 is operated. When the main power switch 36 is operated ("YES" in S2), the control unit 58 proceeds to S4.

[0098] In S4, the control unit 58 switches the reinforcing bar binding machine 2 from the off state to the on state.

[0099] In S6, the control unit 58 operates the first lighting member 100 and the second lighting member 102. The chip LED 114 emits light, so that the first lighting member 100 and the second lighting member 102 emit light. Thus, the reinforcing bar R is irradiated with light.

[0100] In S8, the control unit 58 determines whether the reinforcing bar tying machine 2 is in the single shot mode. When the reinforcing bar tying machine 2 is in the single shot mode ("Yes" in S8), the control unit 58 proceeds to S10. On the other hand, when the reinforcing bar tying machine 2 is not in the single shot mode, that is, when the reinforcing bar tying machine 2 is in the continuous shot mode ("No" in S8), the control unit 58 proceeds to S12.

[0101] In S10, the control unit 58 determines whether the trigger 26 is pulled in based on the detection result of the trigger detection switch 27. When the trigger 26 is pulled in ("Yes" in S10), the control unit 58 proceeds to S14. When the trigger 26 is not pulled in ("No" in S10), the control unit 58 returns to S8.

[0102] In S12, the control unit 58 determines whether the trigger 26 is pulled in and the contact member 46 is pressed in based on the detection result of the trigger detection switch 27 and the detection result of the detection switch 48. When the trigger 26 is pulled in and the contact member 46 is pressed in ("Yes" in S12), the control unit 58 proceeds to S14. On the other hand, when the trigger 26 is not pulled in and / or the contact member 46 is not pressed in ("No" in S12), the control unit 58 returns to S8.

[0103] In S14, the control unit 58 executes the bundling process. Thus, the steel wires W are used to bundle the reinforcing bars R.

[0104] In S16, the control unit 58 determines whether the main power switch 36 is operated. When the main power switch 36 is operated ("Yes" in S16), the control unit 58 proceeds to S18. On the other hand, when the main power switch 36 is not operated ("No" in S16), the control unit 58 returns to S8.

[0105] In S18, the control unit 58 stops the operation of the first lighting unit 100 and the second lighting unit 102. By stopping the light emission of the chip LED 114, the first lighting unit 100 and the second lighting unit 102 do not emit light.

[0106] In S20, the control unit 58 switches the reinforcing steel bar binding machine 2 from the on state to the off state. Figure 8 Processing shown.

[0107] (Effect)

[0108] The steel bar tying machine 2 of this embodiment includes: a twisting motor 74, which operates a holding clamp 78 (an example of a twisting member) that twists the steel wires W around the steel bars R; a main body shell 4, which accommodates the twisting motor 74; and a first lighting member 100, which is retained in the main body shell 4 and irradiates light toward the steel bars R.

[0109] According to the above configuration, when the reinforcing bar tying machine 2 is used in a dark place, the reinforcing bars R are illuminated by the light of the first lighting means 100. Thus, the reinforcing bars R can be easily visually recognized.

[0110] Furthermore, the first lighting member 100 includes a lens 108 (an example of a transmissive portion) that transmits light from the inside of the first lighting member 100 to the outside of the first lighting member 100. The width W1 of the lens 108 is larger than the diameter D1 of the reinforcing bar R.

[0111] According to the above configuration, the width of the light transmitted through the lens 108 is larger than the diameter D1 of the reinforcing bar R. Thus, the entire reinforcing bar R is illuminated. Thus, the reinforcing bar R can be visually recognized more easily.

[0112] The reinforcing bar tying machine 2 further includes an upper curling guide member 68 and a lower curling guide member 70 (an example of a guide member) for winding the steel wire W around the reinforcing bar R. The main body case 4 includes a guide member holding portion 14 for holding the upper curling guide member 68 and the lower curling guide member 70. The first lighting member 100 is disposed on the guide member holding portion 14.

[0113] According to the above configuration, when the reinforcing bar tying machine 2 is used to tie the reinforcing bars R, the upper curl guide member 68 and the lower curl guide member 70 are arranged near the reinforcing bars R. Therefore, the first lighting member 100 is arranged near the reinforcing bars R. Thus, the reinforcing bars R can be visually recognized more easily by the light of the first lighting member 100 .

[0114] Furthermore, the reinforcing bar binding machine 2 further includes a second lighting unit 102 that is held by the main body case 4 and irradiates light toward the reinforcing bars R.

[0115] According to the above-described configuration, the reinforcing bars R can be visually recognized more easily than in a configuration using one lighting member 104 .

[0116] The reinforcing bar tying machine 2 also includes an upper curling guide member 68 and a lower curling guide member 70 (an example of a guide member) for winding the steel wire W around the reinforcing bar R. The main body case 4 includes a guide member holding portion 14 for holding the upper curling guide member 68 and the lower curling guide member 70. The first lighting member 100 and the second lighting member 102 are arranged on the guide member holding portion 14.

[0117] According to the above configuration, when the reinforcing bar tying machine 2 is used to tie the reinforcing bar R, the upper curling guide member 68 and the lower curling guide member 70 are arranged near the reinforcing bar R. Therefore, the first lighting member 100 and the second lighting member 102 are arranged near the reinforcing bar R. Thus, the reinforcing bar R can be visually recognized more easily by the light of the first lighting member 100 and the light of the second lighting member 102.

[0118] When the reinforcing bar tying machine 2 is viewed in the front-rear direction, the upper curl guide member 68 and the lower curl guide member 70 are arranged between the first lighting member 100 and the second lighting member 102 in the left-right direction orthogonal to the front-rear direction.

[0119] According to the above-mentioned structure, when the reinforcing bar R is bundled using the reinforcing bar tying machine 2, the light of the first lighting member 100 and the light of the second lighting member 102 illuminate the reinforcing bar R. When the reinforcing bar R is illuminated by the light of the first lighting member 100, a shadow S1 is formed on the wall surface located behind the reinforcing bar R, while the light of the second lighting member 102 illuminates the shadow S1. In addition, when the reinforcing bar R is illuminated by the light of the second lighting member 102, a shadow S2 is formed on the wall surface located behind the reinforcing bar R, while the light of the first lighting member 100 illuminates the shadow S2. Thus, the shadows S1 and S2 on the wall surface located behind the reinforcing bar R can be made less noticeable. In addition, even if the shadows S1 and S2 on the wall surface located behind the reinforcing bar R move when the reinforcing bar tying machine 2 is moved, it is possible to prevent the user from being attracted by the shadows.

[0120] Furthermore, when the reinforcing bar binding machine 2 is viewed in the front-rear direction, the holding jig 78 is disposed between the first lighting unit 100 and the second lighting unit 102 in the left-right direction perpendicular to the front-rear direction.

[0121] According to the above-described configuration, when the reinforcing bars R are bundled, the shadows S1 and S2 on the wall surface located on the rear side of the reinforcing bars R can be made less noticeable.

[0122] Furthermore, the distance L1 between the first lighting member 100 and the second lighting member 102 is greater than the diameter D1 of the reinforcing bar R. As shown in FIG.

[0123] According to the above-described configuration, when the reinforcing bars R are bundled, the shadows S1 and S2 on the wall surface located on the rear side of the reinforcing bars R can be made less noticeable.

[0124] Furthermore, the luminous flux of the light emitted by the first lighting unit 100 is greater than or equal to 1 lumen and less than or equal to 10,000 lumen.

[0125] According to the above configuration, the reinforcing bars R can be more easily visually recognized by the light of the first lighting member 100 .

[0126] Furthermore, the illuminance of the light emitted by the first lighting member 100 is 70 lux or more and 3000 lux or less at a position 150 mm away from the first lighting member 100 in the irradiation direction of the light.

[0127] According to the above-described configuration, the reinforcing bars R can be more easily visually recognized by the light of the first lighting member 100 .

[0128] Furthermore, the first lighting unit 100 includes a chip LED 114 (an example of a light emitting unit) that emits light and a lens 108 (an example of a diffusion unit) that diffuses the light emitted by the chip LED 114 .

[0129] According to the above-described configuration, compared with a configuration in which the first lighting unit 100 does not include the lens 108 , the irradiation range of the light of the first lighting unit 100 can be expanded.

[0130] The reinforcing bar binding machine 2 further includes a control unit 58 for operating the twisting motor 74 and a wire 128 for connecting the first lighting member 100 and the control unit 58. The main body case 4 includes a handle 18 for the user to hold when using the reinforcing bar binding machine 2, and the wire 128 passes through the handle 18.

[0131] According to the above-mentioned structure, the space in the handle part 18 can be effectively utilized.

[0132] The reinforcing bar binding machine 2 further includes a control unit 58 that can operate the first lighting unit 100 and the twisting motor 74 to perform a binding process of binding the steel wires W around the reinforcing bars R. The control unit 58 causes the first lighting unit 100 to emit light before performing the binding process.

[0133] According to the above-mentioned configuration, when the reinforcing bars R are bundled, the reinforcing bars R can be easily visually recognized.

[0134] The bundling method of this embodiment uses steel wires W to bundle reinforcing bars R. The bundling method includes the steps of irradiating light from a reinforcing bar bundling machine 2 toward the reinforcing bars R, and twisting the steel wires W around the reinforcing bars R while the reinforcing bars R are irradiated with light.

[0135] According to the above-mentioned configuration, when the reinforcing bars R are bundled in a dark place, the reinforcing bars R can be easily visually recognized.

[0136] The method of use of this embodiment is a method of use of a reinforcing bar binding machine 2 for binding reinforcing bars R using a steel wire W. The reinforcing bar binding machine 2 includes: a twisting motor 74 that operates a gripping fixture 78 (an example of a twisting member) that twists the steel wire W around the reinforcing bars R; a trigger 26 that is operated by a user to operate the twisting motor 74; a first lighting member 100 that irradiates light toward the reinforcing bars R; and a control unit 58 (an example of an operating unit) that operates the first lighting member 100. The method of use includes the following steps: operating the first lighting member 100 using the control unit 58; and operating the twisting motor 74 by operating the trigger 26 by the user.

[0137] According to the above configuration, the reinforcing bars R are illuminated by the light of the first lighting member 100. Thus, when the reinforcing bars R are bundled in a dark place, the reinforcing bars R can be easily visually recognized.

[0138] (Second embodiment)

[0139] In the second embodiment, the differences from the first embodiment are described. Fig. 9As shown, the lighting component 104 has a plurality of (four in this embodiment) COB components 214 instead of a plurality of chip LEDs 114. The COB component 214 is a chip-on-board LED. The COB component 214 is mounted on the first surface 110a of the substrate 110. The COB component 214 is connected to the battery pack BP (see Figure 1 ) to emit light. The COB element 214 corresponds to the light emitting unit.

[0140] The lighting member 104 further includes a rib 216 and a fluorescent agent 218. The rib 216 protrudes from the first surface 110a of the substrate 110. The rib 216 is a surrounding wall that surrounds the plurality of COB elements 214 as a whole.

[0141] The fluorescent agent 218 is arranged in the space surrounded by the rib 216. The COB element 214 is arranged inside the fluorescent agent 218. The fluorescent agent 218 diffuses the light emitted by the COB element 214. The fluorescent agent 218 corresponds to a diffusion part. The light diffused by the fluorescent agent 218 is further diffused by the lens 108 while passing through the lens 108.

[0142] (Third embodiment)

[0143] In the third embodiment, the differences from the first embodiment are described. Fig.10 As shown, the wire 128 passes through the guide member holding portion 14, the feed motor storage portion 22, the reel storage portion 24, the connection portion 28, and the control unit storage portion 20 in sequence. The wire 128 is connected to the control substrate 82 in the control unit storage portion 20.

[0144] (Effect)

[0145] In this embodiment, the reinforcing bar binding machine 2 further includes: a feed motor 62 that operates a feed roller 64 (an example of a feed member) that feeds out the steel wire W; a control unit 58 that operates the twisting motor 74 and the feed motor 62; and a lead wire 128 that connects the first lighting unit 100 and the control unit 58. The main body case 4 includes a feed motor housing portion 22 that houses the feed motor 62, and the lead wire 128 passes through the inside of the feed motor housing portion 22.

[0146] According to the above-mentioned structure, the space in the feed motor housing portion 22 can be effectively utilized.

[0147] (Fourth embodiment)

[0148] In the fourth embodiment, the differences from the first embodiment are described. Fig.11As shown, the reinforcing bar binding machine 2 includes an action switch 300. The action switch 300 is disposed on the upper surface of the guide member holding portion 14. The action switch 300 receives an operation by a user to switch between the illumination on state and the illumination off state of the reinforcing bar binding machine 2. When the illumination of the reinforcing bar binding machine 2 is on, the control unit 58 (see Figure 2 ) so that the first lighting member 100 and the second lighting member 102 (refer to Figure 5 ) action. As a result, the first lighting member 100 and the second lighting member 102 emit light. When the reinforcing bar binding machine 2 is in the lighting off state, the control unit 58 stops the first lighting member 100 and the second lighting member 102. As a result, the first lighting member 100 and the second lighting member 102 do not emit light.

[0149] When using the steel wire W to tie the reinforcing bars R, the user first operates the main power switch 36 (see Figure 1 ), so that the reinforcing bar bundling machine 2 is switched from the closed state where it cannot be operated to the open state where it can be operated. At this time, the reinforcing bar bundling machine 2 is in the lighting off state. Next, the user operates the action switch 300, so that the reinforcing bar bundling machine 2 is switched from the lighting off state to the lighting on state. As a result, the first lighting component 100 and the second lighting component 102 emit light. Therefore, the reinforcing bar R is illuminated by the light. Next, the user pulls in the trigger 26. The bundling process is executed by the control unit 58, and the reinforcing bar R is bundled.

[0150] (Corresponding relationship)

[0151] The operation switch 300 is an example of an “operation unit”.

[0154] The first lighting member 100 and the second lighting member 102 are arranged below the lower curling guide member 70 and above the reel 30 and the battery pack BP. When the rebar tying machine 2 is viewed from the rear, the first lighting member 100 and the second lighting member 102 are arranged near the feed roller 64. The first lighting member 100 is arranged to the right of the upper curling guide member 68, the lower curling guide member 70, the holding clamp 78, the center axis AX, and the steel wire W on the feed roller 64.

The distance L1 between the first lighting member 100 and the second lighting member 102 in the left-right direction is greater than the diameter D1 of the rebar R (refer to Figure 5 ).

[0155] (Sixth embodiment)

[0156] In the sixth embodiment, the differences from the first embodiment are described. Fig.13 As shown, the reinforcing bar binding machine 2 includes the first lighting unit 100, and does not include the second lighting unit 102 of the first embodiment. The first lighting unit 100 is disposed on the front surface of the reel storage unit 24. The first lighting unit 100 faces forward.

[0157] The first lighting member 100 is arranged below the feed roller 64 and above the reel 30 and the battery pack BP. The right end of the first lighting member 100 is arranged to the right of the upper curling guide member 68, the lower curling guide member 70, the holding jig 78, and the center axis AX. The left end of the first lighting member 100 is arranged to the left of the center in the left-right direction of the upper curling guide member 68, the lower curling guide member 70, the holding jig 78, and the center axis AX.

[0158] The width W1 of the first lighting member 100 in the vertical direction is larger than the diameter D1 of the reinforcing bar R (see Figure 5 ). The width W1 is greater than 1.5 times and less than 10 times the diameter D1. The width W1 may also be greater than 2 times and less than 5 times the diameter D1. The width W3 of the first lighting component 100 in the left-right direction is greater than the diameter D1 of the steel bar R. The width W3 is greater than 1.5 times and less than 10 times the diameter D1. The width W3 may also be greater than 2 times and less than 5 times the diameter D1. The width W3 is greater than the width W1. In a modified example, the width W3 may also be less than the width W1.

[0159] (Seventh embodiment)

[0160] In the seventh embodiment, the points different from the first embodiment are described. Fig.14As shown in FIG. 1 , the shape of the main body case 4 of the seventh embodiment is different from the shape of the main body case 4 of the first embodiment.

[0161] like Fig.15 As shown in FIG. 1 , the twisting motor storage portion 16 is arranged on the rear side of the guide member holding portion 14. Fig.15 , the reel cover 10 is opened. The control unit 58 is stored in the twisting motor storage section 16. In addition, the cutting unit 54 is arranged in the twisting motor storage section 16 at a position higher than the twisting unit 56. The handle portion 18 is arranged at the lower side of the twisting motor storage section 16. The control unit storage section 20 is arranged at the lower side of the handle portion 18. The battery pack BP is installed at the lower end of the control unit storage section 20 in a detachable manner. The feed motor storage section 22 is arranged on the right side of the twisting motor storage section 16 and on the upper side of the handle portion 18. The reel storage section 24 is arranged at the rear side of the twisting motor storage section 16 and the feed motor storage section 22 and at a position higher than the handle portion 18. Therefore, the reel 30 is arranged at the rear side of the twisting motor storage section 16 and the feed motor storage section 22 and at a position higher than the handle portion 18. The feed unit 50 sends the steel wire W pulled out from the reel 30 forward.

[0162] like Fig.14 As shown in FIG. 1 , the first lighting member 100 and the second lighting member 102 are arranged on the guide member holding portion 14. Fig.16 As shown, the first lighting member 100 and the second lighting member 102 are separated in the left-right direction. The position of the first lighting member 100 in the up-down direction is substantially the same as the position of the second lighting member 102 in the up-down direction. The first lighting member 100 and the second lighting member 102 face forward. The first lighting member 100 and the second lighting member 102 are arranged above the handle portion 18. The first lighting member 100 and the second lighting member 102 are arranged below the upper end of the upper curling guide member 68 and above the lower end of the lower curling guide member 70.

[0163] The first lighting member 100 is arranged on the right side of the upper curling guide member 68, the lower curling guide member 70, the holding fixture 78, and the center axis AX.
