[0092] Hereinafter, an example of embodiment of the present invention will be described in detail with reference to the drawings.

[0093] In the present embodiment, a caulking gun that discharges a filler (sealant or caulking agent) is described as an example of a working machine.

[0094] (Implementation Method 1)

[0095] like Figure 1 to Figure 4 As shown, the caulking gun (working machine) 20 has: an electric motor 2, which is a driving part; a gear box 12, which stores a gear engaged with the electric motor 2; a housing 3, which stores the electric motor 2 and the gear box 12; and a cylindrical holder (holding part) 4, which is connected to the housing 3 and holds the filling tube (storing part) 13 filled with the filler 7 in a detachable manner. In addition, the holder 4 is connected to the housing 3 via a holder fixing part 21. In addition, the caulking gun 20 has: a grip part 5, which extends from the housing 3; an extrusion part 6, which is driven by the electric motor 2 to extrude the filler 7 inside the filling tube 13 held by the holder 4; and a control substrate 8, which is provided with a control circuit for controlling the electric motor 2. Here, the working machine body 1 of the caulking gun 20 is a main body including at least the electric motor 2, the housing 3, the holder 4, the grip part 5, the extrusion part 6, the gear box 12 and the holder fixing part 21.

[0096] In addition, the extrusion unit 6 includes: a rack 6a, which is engaged with the electric motor 2 via a gear; a piston 6b, which is provided at the end of the rack 6a on the filler discharge side (front side) and extrude the filler 7; and a rack handle (handle) 6c, which is provided at the end of the rack 6a on the side opposite to the filler discharge side (rear side). Figure 1 As shown, the rack 6a is arranged along the axis C1 of the cylindrical retainer 4, and the gear portion 6d of the rack 6a engages with the gear in the gear box 12. Therefore, the rack 6a is driven by the electric motor 2, and the rack 6a moves toward the front. In addition, the rack handle 6c is the part that the operator holds when manually pulling back the rack 6a, and the end portion on the rear side of the rack 6a is arranged in the direction opposite to the direction in which the grip portion 5 extends, so that the operator can easily pull it back. As a result, the rack 6a, the piston 6b, and the rack handle 6c are integrated and moved along the Figure 1 The axis C1 is shown to move.

[0097] In addition, a grip portion 5 to be held by an operator is disposed on the operating machine body 1, and a switch 9 is provided on the grip portion 5. The switch 9 is a trigger switch. In addition, a mounting portion 16 capable of mounting a battery pack 10 for supplying power to the electric motor 2 is provided on the side of the grip portion 5 opposite to the switch 9. In addition, a dial 11 is provided in parallel with the switch 9 on the grip portion 5. The dial 11 adjusts the amount of retreat of the rack 6a for preventing dripping of the filler 7 after being ejected. Specifically, it is a function that, when the operator turns off the switch 9, the electric motor 2 is rotated in the reverse direction to retreat the rack 6a to prevent leakage (dripping) of the filler 7, and the amount of retreat of the rack 6a can be appropriately adjusted by the dial 11 according to the viscosity of the filler 7, the air temperature, etc.

[0098] As described above, the caulking gun 20 attaches the filling cartridge 13 filled with the filler 7 to the holder 4, and uses the piston 6b of the extrusion unit 6 to extrude the filler 7 from the nozzle 13b of the filling cartridge 13. The filling cartridge 13 has a cylindrical filling cartridge body 13a and a nozzle 13b attached to the front end of the filling cartridge body 13a.

[0099] In the caulking gun 20, the switch 9 and the dial 11 are electrically connected to the control circuit of the control substrate 8, respectively. That is, when the switch 9 is turned on, power is supplied from the battery pack 10 and current is applied, so that the electric motor 2 is driven. When the electric motor 2 is driven, the rack 6a is driven via the gear in the gear box 12, and the rack 6a starts to move toward the front side. As the rack 6a moves, the piston 6b starts to extrude the filler 7. In addition, the caulking gun 20 is provided with a magnet sensor 15 that can detect the position of the extrusion part 6, and the magnet sensor 15 is electrically connected to the control circuit of the control substrate 8. Moreover, for example, a magnet (magnet) 6e is provided on a part of the rack 6a of the extrusion part 6, and the magnet sensor 15 detects the position of the moving rack 6a by detecting the magnet 6e provided on the rack 6a. Therefore, the control circuit of the control substrate 8 detects that the extrusion part 6 moves to a predetermined position set in advance through the magnet sensor 15, and controls the output of the electric motor 2 to stop through this detection.

[0100] After the extrusion of the filler 7 stops, the electric motor 2 is rotated in the reverse direction to retract the rack 6a by a predetermined distance, thereby preventing dripping from the nozzle 13b. In this drip prevention function, the retraction amount of the rack 6a can be adjusted by the dial 11 as described above.

[0101] Next, the inversion of the caulking gun 20 will be described. The caulking gun 20 is a working machine that can be placed with the working machine body 1 in a manner that the grip portion 5 extends upward relative to the ground surface 14 such as the ground or a block. The situation in which the working machine body 1 is placed in a grounded state with the grip portion 5 extending upward is defined as "inversion". That is, the caulking gun 20 is a working machine that can be inverted relative to the ground surface 14.

[0102] Furthermore, the caulking gun 20 has a plurality of support parts that enable the inversion of the working machine body 1. In the caulking gun 20 of the present embodiment 1, the plurality of support parts are provided on the housing 3, the rack handle 6c of the extrusion part 6, and the holder 4. However, the plurality of support parts only need to be provided on at least the housing 3 and the rack handle 6c of the extrusion part 6.

[0103] exist Figure 2 In the caulking gun 20 shown, a plurality of support portions are provided at the flat upper end portion 3d of the housing 3 and the flat upper end portion 6n of the rack handle 6c. Figure 1The end of the housing 3 shown in FIG. 1 on the side opposite to the grip 5 side with the gear box 12 as the base point is hereinafter referred to as the upper end 3d of the housing 3. In addition, the upper end 6n of the rack handle 6c is Figure 1 The end portion of the rack handle 6c shown in the figure, which is on the opposite side to the connection portion between the rack handle 6c and the rack 6a, is hereinafter referred to as an upper end portion 6n of the rack handle 6c.

[0104] Right now, Figure 2 In the caulking gun 20 shown in the figure, the support portion that enables inversion is provided at the flat upper end portion 3d of the housing 3 and the flat upper end portion 6n of the rack handle 6c. Figure 3 (a), (b) and Figure 4 As shown in FIG. 1 , two first support portions 3a are provided at the upper end portion 3d of the housing 3 as left and right support portions. The first support portion 3a on the right is a grounding portion 3b in contact with the grounding surface 14, and the first support portion 3a on the left is a grounding portion 3c in contact with the grounding surface 14. That is, the first support portion 3a has two grounding portions 3b and 3c. Similarly, Figure 3 (a), (b) and Figure 4 As shown, in Figure 2 The upper end portion 6n of the rack handle 6c shown in the figure is provided with two second support portions 6f as left and right support portions, the second support portion 6f on the right side is a grounding portion 6g in contact with the grounding surface 14, and the second support portion 6f on the left side is a grounding portion 6h in contact with the grounding surface 14. That is, the second support portion 6f also has two grounding portions 6g and 6h.

[0105] also, Figure 2 The caulking gun 20 shown is Figure 1 The caulking tube 13 is not mounted on the holder 4 as shown. Here, the plurality of support parts provided in the caulking gun 20 include a first state support part that can be used when the weight of the caulking tube 13 is in a first state and a second state support part that can be used when the weight of the caulking tube 13 is heavier than the first state. Specifically, the first state is a state in which the remaining amount of the filler 7 in the caulking tube 13 is relatively small and the weight of the caulking tube 13 is light when the caulking gun 20 is inverted, or a state in which the weight of the caulking tube 13 is light. Figure 2 As shown, in the state where the holder 4 is not equipped with the filling cylinder 13, in such a first state, the working machine body 1 is supported by the first state support portion.

[0106] On the other hand, the second state is a state in which the remaining amount of the filler 7 in the filling tube 13 is large and the weight of the filling tube 13 is heavy when the caulking gun 20 is inverted. In such a second state, the working machine body 1 is supported by the second state support part.

[0107] For example, Figure 2The caulking gun 20 shown is inverted in the first state with the battery pack 10 serving as the power source of the electric motor 2 mounted on the mounting portion 16 of the work machine body 1. In the work machine body 1 of such a caulking gun 20, the center of gravity 17 of the work machine body 1 is located between the upper end 3d of the housing 3 of the first support portion 3a and the upper end 6n of the rack handle 6c in the front-rear direction of the work machine body 1. Figure 2 The caulking gun 20 shown is in a state where the rack handle 6c is arranged in the front position. Here, the working machine body 1 in the first state is supported by the first state support portion. In addition, the first state support portion includes a first support portion 3a (grounding portions 3b, 3c) provided at the upper end portion 3d of the housing 3 and a second support portion 6f (grounding portions 6g, 6h) provided at the upper end portion 6n of the rack handle 6c of the extrusion portion 6. Therefore, even in a state where the rack handle 6c is arranged in the front position, the working machine body 1 is supported on both sides of the center of gravity 17 of the working machine body 1 in the front-back direction of the working machine body 1, so that the caulking gun 20 can be stably inverted. Moreover, in the working machine body 1 in the first state, the working machine body 1 is supported at four points based on the four grounding portions 3b, 3c, 6g, and 6h as the first state support portion, so that the stability of the inversion of the caulking gun 20 can be improved.

[0108] then, Figure 5 to Figure 7 The caulking gun 20 shown is in a state where the battery pack 10 is installed on the mounting portion 16 of the working machine body 1, and is in a state where the working machine body 1 in the first state in which the caulking cylinder 13 is not installed on the retaining member 4 is inverted and the rack handle 6c is pulled out to the rear position. In the caulking gun 20 in the state where the battery pack 10 is installed and the rack handle 6c is pulled out to the rear position, the center of gravity 17 of the working machine body 1 of the caulking gun 20 is also located between the upper end 3d of the shell 3 of the first support portion 3a and the upper end 6n of the rack handle 6c in the front-to-back direction of the working machine body 1. In such a caulking gun 20, the working machine body 1 in the first state is also supported by the first state support portion. Here, as Figure 6 as well as Figure 7 As shown, the first state support portion includes a first support portion 3a (grounding portions 3b, 3c) provided at the upper end portion 3d of the housing 3 and a second support portion 6f (grounding portions 6g, 6h) provided at the upper end portion 6n of the rack handle 6c of the extrusion portion 6. Therefore, even when the caulking gun 20 is in a state where the rack handle 6c is pulled out to the rear position, the working machine body 1 can be supported on both sides of the center of gravity 17 of the working machine body 1 in the front-rear direction of the working machine body 1. Thus, the caulking gun 20 can be stably inverted.

[0109] Next, Figure 8 to Figure 10The caulking gun 20 shown has a second state in which the battery pack 10 is mounted on the mounting portion 16 of the working machine body 1 and the filling tube 13 in a state where a relatively large amount of filler 7 remains inside is mounted on the holder 4. Furthermore, the working machine body 1 is inverted and the rack handle 6c is pulled out to the rear position. That is, the caulking gun 20 in the second state in which the weight of the filling tube 13 is heavier than that in the first state because a relatively large amount of filler 7 remains inside is inverted. Figure 8 The filling tube 13 shown is, for example, a filling tube 13 having a capacity of 300 ml. Figure 8 The caulking gun 20 shown is in a state where the rack handle 6c is pulled out to the rear position. In this way, the center of gravity 17 of the working machine body 1 in the second state with the battery pack 10 and the heavy caulking cylinder 13 installed is located between the upper end 3d of the housing 3 of the first support part 3a and the retaining member 4 in the front-to-back direction of the working machine body 1. The working machine body 1 in the second state is supported by the second state support part. Here, as shown in FIG. Fig. 9 as well as Fig.10 As shown, the second state support portion includes a first support portion 3a (grounding portions 3b, 3c) provided at the upper end portion 3d of the housing 3 and a third support portion 4a (grounding portion 4b) provided at the end portion of the notch portion 4c of the retainer 4. Therefore, even if the working machine body 1 in the second state is installed with the battery pack 10 and the heavy filling cylinder 13, the working machine body 1 can be supported on both sides of the center of gravity 17 of the working machine body 1 in the front-to-back direction of the working machine body 1. Thus, the caulking gun 20 in the second state can be stably inverted. Moreover, in the working machine body 1 in the second state, the working machine body 1 is supported at three points based on the three grounding portions 3b, 3c, and 4b as the second state support portion, so that the stability of the inversion of the caulking gun 20 in the second state can be improved.

[0110] In addition, according to the caulking gun (working machine) 20 of the first embodiment, by providing the support portion at the upper end portion 3d of the housing 3 and the upper end portion 6n of the rack handle 6c, even when the position of the center of gravity 17 of the working machine body 1 changes due to the position of the rack handle 6c in the front position and the rear position, the working machine body 1 can be stably inverted in the corresponding state. As a result, the working machine body 1 can be stably inverted, so that the operator can easily hold the inverted working machine body 1, the working efficiency can be improved, and the load on the operator's body can be reduced. Therefore, even when the position of the center of gravity of the working machine body 1 changes, the operability of the caulking gun 20 can be improved. In other words, the operability of the caulking gun 20 can be improved.

[0111] Furthermore, even in a state where the caulking cylinder 13 is attached to the holder 4, the working machine body 1 can be stably inverted, so that the caulking gun 20 can be prevented from falling over.

[0112] Moreover, it is provided with a first state supporting portion and a second state supporting portion that can support the working machine body 1 in a first state and a second state in which the weight of the filling tube 13 is different, and the first support portion 3a provided at the upper end portion 3d of the shell 3 can be used as a common support portion in these first state supporting portion and second state supporting portion, thereby reducing the cost of the caulking gun 20.

[0113] Next, Figure 11 to Figure 13 A caulking gun 20 according to a modified example will be described. Fig.11 The caulking gun 20 of the modified example shown has a working machine body 1 in a second state in which the battery pack 10 is mounted on the mounting portion 16 of the working machine body 1, and a large-capacity caulking cylinder 18 having a larger diameter and a longer length is mounted on the retaining member 4. Moreover, the working machine body 1 is inverted, and the rack handle 6c is pulled out to the rear position. That is, the caulking gun 20 in the second state is inverted by installing the large-capacity caulking cylinder 18 having a larger diameter and a longer length. The caulking gun 20 in the second state is inverted. The center of gravity 17 of the working machine body 1 in the second state in which the battery pack 10 is installed and the large-capacity caulking cylinder 18 is installed is located between the upper end portion 3d of the shell 3 of the first support portion 3a and the retaining member 4 in the front-to-back direction of the working machine body 1. The working machine body 1 in the second state in which such a large-capacity caulking cylinder 18 is installed is also supported by the second state support portion. Here, as Fig.12 as well as Fig.13 As shown, the second state support portion of the caulking gun 20 of the modified example also includes: a first support portion 3a (grounding portion 3b, 3c), which is provided at the upper end portion 3d of the housing 3; and a third support portion 4a (grounding portion 4b), which is provided at the end portion of the notch portion 4c of the retainer 4. Fig.11 As shown, even in the second state of the working machine body 1 with the battery pack 10 and the large-capacity filling cylinder 18 installed, the working machine body 1 can be supported on both sides of the center of gravity 17 of the working machine body 1 in the front-rear direction of the working machine body 1. Therefore, even in the second state of the caulking gun 20 with the large-capacity filling cylinder 18 installed, it can be stably inverted. In addition, in the working machine body 1 in the second state with the large-capacity filling cylinder 18 installed, the working machine body 1 is supported at three points based on the three grounding parts 3b, 3c, and 4b as the second state support part, so that the inversion stability of the caulking gun 20 in the second state with the large-capacity filling cylinder 18 installed can be improved.

[0114] (Implementation Method 2)

[0115] right Figure 14 to Figure 16 The caulking gun 20 of the second embodiment shown will be described. Fig.14The caulking gun 20 of the second embodiment shown has a working machine body 1 in a second state in which the battery pack 10 is mounted on the mounting portion 16 of the working machine body 1, and the filling cylinder 13 in a state in which a relatively large amount of filler 7 remains inside is mounted on the retaining member 4. Moreover, the working machine body 1 is inverted, and the rack handle 6c is pulled out to the rear position. That is, the caulking gun 20 in the second state in which the filling cylinder 13 is heavier is inverted, and the rack handle 6c is pulled out to the rear position. In this way, the center of gravity 17 of the working machine body 1 in the second state in which the battery pack 10 is mounted, the filling cylinder 13 of relatively heavy weight is mounted, and the rack handle 6c is pulled out to the rear position is located near the retaining member fixing portion 21. In other words, Fig.14 The center of gravity 17 of the working machine body 1 in the second state shown is located between the upper end 6n of the rack handle 6c and the holder 4 in the front-rear direction of the working machine body 1. Fig.14 In the caulking gun 20 shown in FIG. 1 , the second support portion 6f (grounding portions 6g, 6h) provided at the upper end portion 6n of the rack handle 6c has high protrusions 6i, 6j, and the upper end portion 6n of the rack handle 6c is arranged at a position higher than the housing 3. Fig.15 as well as Fig.16 As shown, the upper end 6n of the rack handle 6c is wider in the left-right direction. Fig.14 In the working machine body 1 in the second state shown in FIG. 1 , the working machine body 1 is also supported by the second state support portion. Fig.15 as well as Fig.16 As shown, the second state support portion includes: a second support portion 6f (grounding portion 6g, 6h) provided at the upper end portion 6n of the rack handle 6c; and a third support portion 4a (grounding portion 4b) provided at the end portion of the notch portion 4c of the holder 4. Moreover, the grounding portions 6g, 6h are provided with protrusions 6i, 6j having a high height and a wide width in the left-right direction. In this way, the grounding portions 6g, 6h are provided with protrusions 6i, 6j having a high height and a wide width in the left-right direction. Therefore, even if the working machine body 1 in the second state is installed with the battery pack 10 and the heavy filling cylinder 13 installed and the rack handle 6c is pulled out to the rear position, the working machine body 1 can be supported on both sides of the center of gravity 17 of the working machine body 1 in the front-rear direction of the working machine body 1. As a result, the caulking gun 20 in the second state of the present embodiment 2 can be stably inverted. In addition, even if the position of the center of gravity 17 of the working machine body 1 is changed to near the retaining member fixing portion 21, the working machine body 1 can be stably inverted because the grounding portions 6g and 6h of the upper end portion 6n of the rack handle 6c have protrusions 6i and 6j that are relatively high and relatively wide in the left-right direction.

[0116] (Implementation 3)

[0117] right Figure 17 to Figure 23 The caulking gun 20 of the third embodiment shown will be described. Fig.17 The caulking gun 20 of the third embodiment shown in FIG. 1 has the battery pack 10 mounted on the mounting portion 16 of the working machine body 1, and the working machine body 1 is in a first state where the caulking cylinder 13 is not mounted. Therefore, the caulking gun 20 of the third embodiment can be flexibly used as Fig. 20 As shown, the state of being hung on the single tube pipeline 19 and being maintained as Fig.21 As shown, the working machine body 1 is in an inverted state.

[0118] Figures 17 to 20 The structure of the caulking gun 20 that can be hooked and held on the single-tube pipe 19 is shown. Fig.18 as well as Fig.19 As shown, the rack handle 6c is connected to L-shaped movable handles 6k and 6m, respectively, and the movable handles 6k and 6m are in a closed state so that the L-shaped parts coincide (closed state). As a result, the operating part of the rack handle 6c becomes a length L1, which is longer than the rack handle 6c of the first embodiment. By making the length L1 of the operating part of the rack handle 6c longer than Fig. 20 The diameter of the single-tube pipe 19 is slightly longer (for example, 48.6 mm), so that the caulking gun 20 can be hooked and held on the single-tube pipe 19 at a work site or the like.

[0119] In addition, if Fig. 22 as well as Fig.23 As shown in FIG. 1 , the movable handle 6k and the movable handle 6m can be tilted outward by 90° at the fulcrum P1 (open state). Fig.21 As shown, the movable handles 6k, 6m and the holder fixing portion 21 can be used to support the working machine body 1, and the caulking gun 20 can be stably inverted. In addition, the movable handles 6k and 6m are respectively made of iron materials, and are respectively provided with magnets, so that the open state of each other can be suppressed from becoming the closed state, or the closed state can be suppressed from becoming the open state, and the closed state and the open state of the movable handles 6k and 6m can be respectively maintained.

[0120] Furthermore, by inverting the movable handle 6k and the movable handle 6m in a tilted state, the height of the working machine body 1 when inverted can be lowered.

[0121] As described above, the caulking gun 20 of the third embodiment can flexibly use two supporting states: a state in which the caulking gun 20 is hooked and held on the single-tube pipe 19 and a state in which the caulking gun 20 is inverted.

[0122] (Implementation 4)

[0123] right Fig.24 as well as Fig.25 The caulking gun 25 of the fourth embodiment shown will be described. Fig.24 The caulking gun 25 of the fourth embodiment shown has a battery pack 10 mounted on the mounting portion 16 of the working machine body 1, and the caulking cylinder 13 is mounted. In the fourth embodiment, the caulking gun 25 is placed upright by the bracket 22. Fig.24 As shown in (b), the caulking gun 25 has a bracket 22 that can rotate 180 degrees with a hinge 23 as a fulcrum at the lower part of the front end of the holder 4. Moreover, the bracket 22 is made of iron, for example, and a magnet 24 is provided at the contact point between the holder 4 and the bracket 22, so that the bracket 22 is not easily separated from the holder 4. In addition, as shown in FIG. Fig.25 As shown in (a), the front end of the bracket 22 is in an arc shape in accordance with the cylindrical retainer 4, so that Fig.24 When the bracket 22 is stored in the holder 4 as shown in (b), the bracket 22 does not protrude unnecessarily. Fig.25 As shown in (b), when the bracket 22 is rotated in the rotation direction Q1 and the caulking gun 25 is placed upright on the ground surface 14 using the bracket 22, the arc-shaped bracket 22 supports the ground surface 14 at two points, so the working machine body 1 can be placed upright stably.

[0124] The present invention is not limited to the above-mentioned embodiments 1 to 4, and various changes can be made without departing from the scope of the gist thereof. For example, in the above-mentioned embodiment 3, when the working machine body 1 is inverted, the grounding portion 4b of the third support portion 4a of the retainer 4 can be set to a protrusion shape with a higher height, and the working machine body 1 can be supported by the movable handle 6k and the movable handle 6m and the grounding portion 4b of the third support portion 4a of the retainer 4. In this case, the caulking gun 20 can also be stably inverted. In addition, the dial 11 can also adjust the extrusion speed of the rack 6a for discharging the filler 7. Specifically, the extrusion speed of the rack 6a can be appropriately adjusted by the dial 11 according to the viscosity of the filler 7, the air temperature, etc.
