Summary of the Invention

Problems to be Solved by the Invention

[0004] As described in Patent Document 1 above, in a conventional binding machine, the driver is generally driven by an air cylinder. However, in such a configuration, the binding machine can only be used near a compressor or the like, which is an air supply source. In addition, since it is necessary to connect the compressor and the binding machine with a hose, it is also necessary to consider the routing of the hose. Furthermore, since hoses, air pipes, etc. are required, the size of the device increases.

[0005] It is also conceivable to use an electric motor instead of an air cylinder as the power source of the driver. In that case, although the increase in the size of the device can be suppressed by using an electric motor, in addition to the fact that the binding machine can only be used near a power outlet, it is also necessary to consider the routing of the power cord.

[0006] The present invention aims to provide a binding machine that can be used in various locations. [Means for solving the problem]

[0007] The binding machine according to the present invention is a binding machine that binds objects to be bound with staples, and comprises a driver that pushes staples toward the objects to be bound, a clincher that deforms staples by clamping them together with the driver, an electric motor that drives the driver, and a battery mounting section to which a storage battery unit for supplying power to the electric motor is attached.

[0008] The strapping machine with the above configuration uses power supplied from a battery unit to operate an electric motor, which drives a driver to perform strapping. In addition to being usable in locations where there is no nearby compressor or power outlet, there is no need to consider the routing of hoses or power cords, so it is not restricted by location and can be used in a variety of places. [Effects of the Invention]

[0009] The present invention provides a binding machine that can be used in various locations. [Brief explanation of the drawing]

[0011] This embodiment will now be described with reference to the attached drawings. To facilitate understanding of the explanation, the same reference numerals are used for identical components in each drawing whenever possible, and redundant explanations are omitted.

[0012] A first embodiment will now be described. The binding machine 10 according to this embodiment is a device for binding the opening portion of bags containing fruits and vegetables, and is used, for example, in the back room of a supermarket. Figures 1 to 3 show the external appearance of the binding machine 10.

[0013] Figure 4 shows the bag BG after bundling using the bundling machine 10. The bag BG contains fruits and vegetables or the like inside, and its entrance portion is bundled by staples 80. The staples 80 are, for example, substantially rod-shaped members formed of resin. The staples 80 are wound around the entrance portion of the bag BG by the bundling machine 10 to bundle the entrance portion. Note that the object to be bundled may be the bag BG as in this embodiment, or may be other objects. The configuration of the bundling machine 10 described below can also be applied to, for example, a bundling machine for bundling a plurality of members together.

[0014] Figure 5 shows the shape of the staples 80 in the initial state before bundling. As shown in the figure, the staples 80 have a shape in which a pair of legs 81 are connected by a connecting portion 82, and the whole is substantially U-shaped. On the opposite side of the connecting portion 82, the space between the respective legs 81 is open.

[0015] In order to be able to continuously perform bundling by the bundling machine 10, the staples 80 are arranged in a plurality along the depth direction of the paper surface in FIG. 5, and are connected to each other via a connecting portion 83. In other words, the plurality of staples 80 are integrally formed so as to be connected to each other via the connecting portion 83 and form a single string-like shape. The plurality of staples 80 connected and formed into a string-like shape are hereinafter also referred to as "connector 800". The connector 800 is held by a connector holding portion 170 (see FIG. 1) of the bundling machine 10 in a state of being wound around a bobbin 700 as shown in FIG. 6.

[0016] The configuration of the strapping machine 10 will be explained with reference to Figure 1 and other figures. In Figure 1, the direction from left to right on the page is defined as the x-direction, and the x-axis is set along this direction. The direction perpendicular to the x-direction, from the back of the page to the front of the page, is defined as the y-direction, and the y-axis is set along this direction. Furthermore, the direction perpendicular to both the x-direction and the y-direction, from the bottom of the page to the top of the page, is defined as the z-direction, and the z-axis is set along this direction. In the other figures, the x-axis, y-axis, and z-axis are set to correspond to those in Figure 1. In the following explanation, the terms "x-direction," "y-direction," and "z-direction" will be used as appropriate. Figure 1 is a view of the strapping machine 10 from the y-direction side, Figure 2 is a view of the strapping machine 10 from the -y-direction side, and Figure 3 is a view of the strapping machine 10 from the x-direction side.

[0017] First, let me explain the components of the strapping machine 10 that are visible externally. The strapping machine 10 comprises a main frame 100, a connecting body holding part 170, a motor unit 20, a storage battery unit 60, and a cutter unit 500.

[0018] The main frame 100 is the main body portion of the strapping machine 10 and holds each component of the strapping machine 10. The main frame 100 is constructed by combining multiple substantially flat plate-shaped members, etc., which are parallel to the plane of the paper in Figure 1. A handle 150 is provided at the upper end of the main frame 100 for gripping by the user of the strapping machine 10.

[0019] A guide groove 110 is formed in the main frame 100 so as to extend downward from its upper end. A switch member 111 is provided at the lower end of the guide groove 110. The user of the strapping machine 10 passes the portion of the bag BG to be strapped through the guide groove 110 and lowers the bag BG along the guide groove 110. When the bag BG hits the switch member 111 and rotates the switch member 111, an internal driver 30 (not shown in Figure 1, see Figure 9) etc. operates as will be explained later, and the opening portion of the bag BG is strapped with staples 80.

[0020] The connecting body holding portion 170 is the part that holds the bobbin 700 around which the connecting body 800 is wound. The connecting body holding portion 170 includes a projection 171 (in this embodiment formed as a rod-shaped shaft extending along the width direction) that protrudes in the y direction (i.e., the width direction of the binding machine 10), and the base end of the projection 171 (the far end in Figure 1) is connected to the main body frame 100. As shown in Figure 6, a through hole 701 is formed in the center of the bobbin 700. As shown in Figure 1, the bobbin 700 is attached to the binding machine 10 by passing the through hole 701 through the connecting body holding portion 170. As a result, the connecting body 800 is held in a wound state around the connecting body holding portion 170 and is pullable forward (generally in the x direction). Furthermore, when the strapping machine 10 is in use, as shown in Figure 7, the connecting body 800 pulled out from the bobbin 700 extends to the guide section 160, but this is omitted from the illustration in Figures 1 to 3.

[0021] Furthermore, a configuration different from the above may be used for holding the bobbin 700. For example, the protruding portion 171 may be configured to protrude in the z-direction. Alternatively, the connecting body holding portion 170 may not have a protruding portion 171 that is inserted through the through hole 701, and may be configured to hold the bobbin 700 from the outer circumference.

[0022] The guide section 160 includes a roller 161, which is a first guide section, and a guide rail 162, which is a second guide section. The roller 161 curves the connecting body 800, which is pulled out from the bobbin 700 of the connecting body holding section 170, inward. Here, "inward" refers to the -y direction side, that is, the direction toward the main frame 100, the driver 30, etc. Both the roller 161 and the guide rail 162 are members that guide the connecting body 800, which is pulled out from the bobbin 700 as described above, to a predetermined position on the main frame 100. As shown in Figures 1 and 3, the roller 161 and the guide rail 162 are provided at positions on the y-direction side of the main frame 100.

[0023] Figure 8 shows an enlarged view of the roller 161, guide rail 162, and their vicinity from Figure 3, along with the connecting body 800 that they guide. In Figure 8, some of the structures shown in Figure 3 have been omitted to make the connecting body 800 easier to see.

[0024] The roller 161 is a roughly cylindrical rotating body positioned with its rotational axis aligned with the z-direction. The connecting body 800 is pulled out from the bobbin 700 and generally pulled out towards the x-direction, and then guided along the side of the roller 161 to change its orientation generally towards the -y-direction. As shown in Figure 8, the connecting body 800 is guided by the roller 161 with the connecting portions 82 of each staple 80 facing inward and the tips of the leg portions 81 facing outward. In this embodiment, the orientation of the connecting body 800 pulled out from the bobbin 700 is changed by the roller 161, but it is not necessarily limited to a roller, and for example, a guiding member such as a guide rail may be used to change its orientation.

[0025] As shown in Figure 1, the guide rail 162 is positioned slightly to the x-direction of the roller 161. As shown in Figure 8, the guide rail 162 extends linearly from the vicinity of the roller 161 toward the -y-direction. The guide rail 162 is a generally flat plate-shaped member, positioned with its normal direction aligned with the z-direction.

[0026] The connecting body 800 is configured such that the guide rail 162 is inserted from the x-direction side between the pair of legs 81 of the staple 80. This holds the connecting body 800 in a state where it can slide along the guide rail 162 in the -y-direction. The staple 80 at the very front of the connecting body 800 is positioned in the area of ​​the main frame 100 through which the driver 30 described later passes (i.e., the operating area of ​​the driver 30), and is used to fasten the bag BG in the next operation. The guide rail 162 can be said to guide the connecting body 800, which has been pulled out from the connecting body holding part 170, along the width direction (y-direction) to the operating area of ​​the driver 30.

[0027] As described above, in this embodiment, the connecting body 800 pulled out from the bobbin 7800 is bent by approximately 90 degrees by the roller 161 and guided to the guide rail 162. In this configuration, the bobbin 700 can be positioned upright. In other words, the bobbin 700 can be held with the orientation of the through hole 701 aligned horizontally rather than vertically. This makes it possible to keep the overall width dimension of the binding machine 10, including the bobbin 700, small.

[0028] As shown in Figure 8, a feed member 280 is provided on the upper side of the guide rail 162, and a check member 290 is provided on the lower side of the guide rail 162.

[0029] The feed member 280 is a plate-shaped member with a feed claw 282 formed at its tip. The feed member 280 is attached to the link member 270 via a shaft 281. The feed member 280 is rotatable around the shaft 281 and is biased in the clockwise direction in Figure 8 by a spring (not shown).

[0030] The link member 270 is a member that is operably attached to the main frame 100. The portion of the link member 270 to which the feed member 280 is attached is biased toward the -y direction by a spring (not shown). The feed member 280 is biased toward the -y direction as described above, with the feed claw 282 inserted into a part of the connecting body 800. Therefore, the connecting body 800 is also biased toward the -y direction by the force from the feed claw 282.

[0031] When the binding is performed by the binding machine 10, the staple 80 that was at the very tip of the connecting body 800 disappears, and the force from the feed claw 282 feeds the connecting body 800 toward the -y direction. Subsequently, the link member 270 moves toward the y direction by a mechanism not shown. As the feed claw 282 moves toward the y direction together with the link member 270, it detaches from the connecting body 800 once, and then re-enters a part of the connecting body 800 at a position one step further toward the y direction than before.

[0032] The check valve member 290 is a plate-shaped member with a check claw 292 formed at its tip. The check valve member 290 is attached to the base member 102 via a shaft 291. The base member 102 is a member attached to the main frame 100. The check valve member 290 is rotatable around the shaft 291 and is biased in the counterclockwise direction in Figure 8 by a spring (not shown). The check valve member 290 is in a state where the check claw 292 is inserted into a part of the connecting body 800.

[0033] When the binding machine 10 performs the binding, the feed claws 282 operate as described above, and the connecting body 800 is fed in the -y direction. The check member 290 is a member that prevents the connecting body 800 from moving in the reverse direction at that time, by the check claws 292.

[0034] Let's return to Figure 1 and continue the explanation. The motor unit 20 houses the electric motor 50 and other components inside. The electric motor 50 is a rotating electric machine provided as a drive source for operating the binding machine 10. The electric motor 50 operates by receiving power from the battery unit 60 and drives the driver 30, which will be described later. Inside the motor unit 20, in addition to the electric motor 50, there is also a control board (not shown) for controlling the operation of the binding machine 10.

[0035] The motor unit 20 is located on the lower part of the main frame 100, on the y-direction side. A switch 25 is provided on the y-direction side of the motor unit 20. When the user operates the switch 25, the control board is activated, and the bundling machine 10 enters standby mode.

[0036] The battery unit 60 is a unitized system combining a battery (e.g., a lithium-ion battery) for storing the power necessary for the operation of the strapping machine 10 with a control board 62 (see Figure 3) for controlling the charging and discharging of the battery. The battery unit 60 is pre-charged by an external charger and then installed in the battery mounting section 600 of the strapping machine 10. The power supplied from the battery unit 60 via the battery mounting section 600 is supplied to the electric motor 50 and also to the control board for controlling the operation of the strapping machine 10. As shown in Figure 3, a display unit 61 is provided on the outer surface of the battery unit 60. The display unit 61 displays information such as the remaining battery charge by the illumination status of LEDs.

[0037] In this embodiment, the battery mounting section 600 is provided on the bundling machine 10 as part of the motor unit 20. Specifically, the portion of the motor unit 20 that is on the x-direction side and the -y-direction side is configured as the battery mounting section 600. As shown in Figure 3, a space for arranging the storage battery unit 60 is formed between the battery mounting section 600 and the main frame 100. The user can attach the storage battery unit 60 to the battery mounting section 600 by sliding the storage battery unit 60 towards the -x direction while facing the battery mounting section 600 from the -y-direction side. In other words, the battery mounting section 600 is configured to attach the storage battery unit 60 by sliding it in a predetermined direction (-x direction). The storage battery unit 60 is held by the battery mounting section 600 with its internal control board 62 perpendicular to the y-direction (width direction).

[0038] The cutter unit 500 is used to cut off the excess portion of the bag BG beyond the staples 80 after the bag BG has been secured. The cutter unit 500 has a straight groove 501 formed therein, and a blade 510 is provided along the inner surface of the groove 501.

[0039] Once the bag BG is secured, the user can pull the bag BG up along the guide groove 110, then move the bag BG inside the groove 501, and cut off the excess portion of the bag BG with the blade 510. Alternatively, the bag BG may be configured to automatically cut off after the securing is complete by a mechanism not shown.

[0040] The internal configuration of the strapping machine 10 will be explained with reference primarily to Figure 9. As shown in the figure, the strapping machine 10 includes reduction gears 210 and 220, a cam gear 230, a crank 240, a coupling link 250, a driver 30, and a clincher 400. All of these are located inside the main frame 100 and are held in place by the main frame 100.

[0041] The reduction gears 210 and 220 are a pair of gears that mesh with each other, and they transmit the rotation of the drive shaft 51 of the electric motor 50 to the cam gear 230, which will be described later, while reducing its speed. The drive shaft 51 is provided with its longitudinal direction aligned with the width direction (y direction), and a part of it is embedded inside the main frame 100. The portion of the drive shaft 51 embedded inside the main frame 100 is equipped with a gear that meshes with the reduction gear 210, but this gear is not shown in Figure 9.

[0042] The cam gear 230 rotates upon receiving force from the reduction gear 220 and is a component that operates the crank 240. The crank 240 is rotatably mounted to the vicinity of the outer circumference of the cam gear 230 via a shaft 231. As the cam gear 230 rotates, the crank 240 reciprocates along the x-axis, changing its angle as appropriate. Figure 9 shows the state when the crank 240 is furthest towards the -x direction, and Figure 10 shows the state when the crank 240 is furthest towards the x direction. In the standby state before binding is performed, the state is as shown in Figure 9.

[0043] The connecting link 250 is a component that connects the crank 240 and the driver 30. One end of the connecting link 250 is rotatably attached to the end of the crank 240 opposite to the shaft 231 via the shaft 251. The other end of the connecting link 250 is rotatably attached to the end of the driver 30 on the -x direction side via the shaft 261. Force from the crank 240 is transmitted to the driver 30 via the connecting link 250.

[0044] The driver 30 is a component for pushing the staple 80 toward the bag BG (object to be stapled) which is passed through the guide groove 110. Inside the main frame 100, a pair of guide members 121 and 122 are provided, facing each other along the z direction, and a part of the driver 30 is sandwiched between them. The guide members 121 and 122 hold the driver 30 in a state where it can move only in the direction along the x axis. In other words, the direction of movement of the driver 30 is along the x axis. The position where the guide members 121 and 122 are provided is the position where the tip portion of the driver 30 on the x-direction side is sandwiched from above and below in the state shown in Figure 9, and corresponds to the position of the guide rail 162 mentioned earlier.

[0045] When the crank 240 is operated by the driving force of the electric motor 50, the driver 30 moves from the position in Figure 9 to the position in Figure 10. At this time, the x-side end of the driver 30 strikes the staple 80 at the very front (i.e., the -y side) of the connecting body 800, pushing the staple 80 toward the x-side. After the staple 80 is separated from the other staples by the cutting of the connecting portion 83, it moves toward the x-side together with the tip of the driver 30.

[0046] The clincher 400 is a component that deforms the staple 80 by clamping it together with the driver 30 as described above. As shown in Figure 9, the position where the clincher 400 is provided is opposite the tip of the driver 30 from the x-direction side, and is further towards the x-direction than the guide groove 110. On the -x-direction side surface of the clincher 400, that is, the clinching surface opposite the tip of the driver 30, a groove (not shown) is formed to guide the deformation of the leg portion 81 of the staple 80.

[0047] The staple 80 is pushed out in the x-direction by the driver 30 with the tip of its leg portion 81 facing the clincher 400. When the driver 30 reaches the position furthest to the x-direction within its range of motion, the tip of the leg portion 81 contacts the clinching surface of the clincher 400 and deforms into a predetermined shape while being guided by the groove on the clinching surface. At this time, the opening portion of the bag BG is sandwiched between the legs 81. Therefore, the opening portion of the bag BG is fastened by the deformed staple 80, resulting in the state shown in Figure 4.

[0048] Inside the main frame 100, in addition to the driver 30 and clincher 400 described above, a convergence member 300 and a link member 260 are further provided.

[0049] The converging member 300 is a member used to pre-converge the portion of the bag BG (object to be bound) that passes through the guide groove 110 so that it is sized to be sandwiched between the legs 81 of the staple 80 before binding. The converging member 300 is a substantially flat plate parallel to the xz plane. One end of the converging member 300 along its longitudinal direction is provided with a pressing portion 320 that abuts against and presses against the bag BG. The other end of the converging member 300 along its longitudinal direction has a rotating hole through which the shaft 311 passes. The shaft 311 is a cylindrical shaft extending along the y direction, and its y-direction end is attached to the main frame 100. The converging member 300 is supported in a state that allows it to rotate around the shaft 311.

[0050] The convergent member 300, which is roughly flat, has an elongated hole 312 that penetrates it in the y-direction. The elongated hole 312 is a long, narrow hole formed to extend from the shaft 311 side toward the pressing part 320 side. The shaft 262, provided on the link member 260 described later, is inserted through the elongated hole 312. The convergent member 300 rotates around the shaft 311 due to the force it receives from the shaft 262. In the standby state before the binding operation is performed (Figure 9), the convergent member 300 is in standby position at the most clockwise position within its range of motion due to the force from the spring 351. In this state, the entire convergent member 300 does not overlap with the guide groove 110, and the pressing part 320 is positioned above the guide groove 110.

[0051] The link member 260 is a component for operating the converging member 300 in conjunction with the operation of the driver 30. The link member 260 is held in a state in which it can be moved parallel only in the direction along the x-axis. Like the converging member 300, the link member 260 is a substantially flat plate parallel to the xz plane. One end of the link member 260 along its longitudinal direction overlaps a part of the converging member 300 from the y-direction side. The shaft 262 described above is provided in this portion, and this shaft 262 is inserted through the elongated hole 312.

[0052] A circular hole is formed in the other end of the link member 260 along its longitudinal direction, and a shaft 261 is inserted through this hole. As mentioned earlier, the shaft 261 is the shaft that rotatably connects the coupling link 250 and the driver 30.

[0053] In the configuration described above, when the driver 30 moves in the x-direction, the link member 260 also moves in the x-direction along with the driver 30. The shaft 262 of the link member 260 moves in the x-direction while remaining inserted through the elongated hole 312 of the converging member 300. The converging member 300 rotates in the counterclockwise direction in Figure 9, resisting the force of the spring 351 due to the force that the edge of the elongated hole 312 receives from the link member 260. As a result, the pressing portion 320 of the converging member 300 moves downward along the guide groove 110, reaching the state shown in Figure 10.

[0054] The sequence of operations when the strapping machine 10 straps the bag BG will now be explained again. When the user passes the bag BG through the guide groove 110 and lowers it, and rotates the switch member 111, the electric motor 50 is driven. The driving force of the electric motor 50 causes the cam gear 230 and crank 240 to operate, moving the driver 30 in the x direction. The driver 30 moves from the standby position shown in Figure 9 to the strapping completed position shown in Figure 10.

[0055] Simultaneously, the link member 260 moves toward the x-direction along with the driver 30, causing the converging member 300 to rotate counterclockwise. The pressing portion 320 of the converging member 300 moves downward along the guide groove 110, and its tip comes into contact with the bag BG. The portion of the bag BG that passes through the guide groove 110 is deformed by the pressure from the pressing portion 320, and becomes pre-converged before the staples 80 reach it.

[0056] As described above, the driver 30 moves toward the x-direction, pushing the staple 80 that was at the tip of the connector 800 toward the x-direction. The staple 80 moves toward the bag BG located toward the x-direction, with the tip of its leg portion 81 pointed toward the clincher 400.

[0057] By the time the staple 80 reaches the position of the bag BG, the bag BG has converged due to being pressed by the pressing part 320 as described above, and is small enough to be sandwiched between the legs 81. Therefore, the staple 80 reaches the position of the clincher 400 while inserting the bag BG between the legs 81. After that, the staple 80 is deformed by being sandwiched between the driver 30 and the clincher 400, and the bag BG is fastened together.

[0058] Even after the binding is complete, the electric motor 50 continues to operate. The driver 30 moves from the position shown in Figure 10 toward the -x direction. Consequently, the converging member 300 rotates clockwise. Finally, each member returns to the standby position shown in Figure 9, at which point the electric motor 50 stops operating. During the period from when the electric motor 50 starts operating for binding until it stops, the cam gear 230 rotates 360 degrees.

[0059] As described above, the strapping machine 10 according to this embodiment is configured to operate an electric motor 50 using power from a storage battery unit 60 attached to the battery mounting section 600, thereby driving a driver 30 and the like to strap the bags BG. Unlike configurations in which an air cylinder drives the driver 30 and the like, the strapping machine 10 can be used even in places where there is no compressor nearby, and there is no need to consider the routing of hoses. Furthermore, since a power cord connected to an outlet is not required, the strapping machine 10 can be used even in places where there is no outlet such as on a wall, and there is no need to consider the routing of power cords. Therefore, the strapping machine 10 can be used in a variety of locations without being restricted by location.

[0060] Various positions can be adopted for the battery mounting section 600, taking into consideration workability and other factors. For example, as in this embodiment, it is preferable that the battery mounting section 600 be located on the driver 30 side (i.e., on the -x side) of the position where the staple 80 is sandwiched between the driver 30 and the clincher 400 (hereinafter referred to as the "fastening position"). By positioning the battery mounting section 600 in such a location, for example, when viewed along the width direction as shown in Figure 1, the storage battery unit 60 will be mounted in a position that avoids being directly below the fastening position. This reduces the possibility that the storage battery unit 60 will interfere with the user's work of lowering the bag BG along the guide groove 110, thus allowing for a wider work area.

[0061] As shown in Figure 9, the battery mounting section 600 in this embodiment is located below the driver 30. Since the relatively heavy battery unit 60 is attached to the lower part of the strapping machine 10, it is possible to prevent the center of gravity of the strapping machine 10 from becoming too high and unstable. Here, "below the driver 30" means not only directly below the driver 30, but also all positions below the driver 30, that is, positions on the -z side of the driver 30's position.

[0062] In this embodiment, a connecting body holding section 170 for holding the connecting body 800 and a guide section 160 including a roller 161 and a guide rail 162 are provided, and multiple staples 80 are sequentially fed from the connecting body holding section 170 towards the guide rail 162 via the roller 161. In such a configuration, as is clear from, for example, Figures 1 and 3, the bobbin 700 and the guide rail 162 protrude in the y-direction, creating a relatively large space below them. Therefore, in the stapling machine 10 according to this embodiment, a battery mounting section 600 is provided in the space below the connecting body holding section 170 and the guide rail 162, and the battery unit 60 is arranged in the existing space described above. This suppresses the increase in size of the device due to the addition of the battery unit 60.

[0063] Furthermore, the battery mounting section 600 may be provided in a position that spans both the connecting body holding section 170 and the guide rail 162, that is, below the area between the connecting body holding section 170 and the guide rail 162, or below at least one of them.

[0064] As shown in Figure 3, the connecting body holder 170, the guide rail 162, the electric motor 50, and the battery mounting section 600 are each located on the same side of the main frame 100 along the width direction (specifically, the y-direction side of the main frame 100). By arranging each component in this way, the dimensions of the strapping machine 10 along the width direction can be reduced. In addition, since the user can access each part from one side of the main frame 100, the workability of the strapping machine 10 is also improved.

[0065] As mentioned earlier, a handle 150 is provided at the upper end of the main frame 100 for the user to grip the strapping machine 10. When viewed along the width direction (y direction) as shown in Figure 1, the handle 150 is positioned above the electric motor 50 and the battery mounting section 600. By providing the handle 150 directly above the relatively heavy electric motor 50 and battery unit 60, it is made even easier for the user to carry the strapping machine 10.

[0066] Furthermore, the handle 150 may be provided in a position above the area that spans both the electric motor 50 and the battery mounting section 600, or it may be provided in a position above at least one of them.

[0067] As shown in Figure 1, etc., a through hole 101 is formed in the main frame 100 at a position adjacent to the battery mounting section 600 (specifically, on the x-side of the battery mounting section 600) in the direction in which the battery unit 60 is slid when attaching it to the battery mounting section 600, and the hole penetrates the main frame 100 along the y-direction. When attaching or detaching the battery unit 60 from the y-side of the main frame 100, the user can do so without touching the main frame 100 with their hands.

[0068] The second embodiment will be described with reference to Figure 11. Below, we will mainly describe the differences from the first embodiment, and will omit explanations of points common to both embodiments as appropriate.

[0069] This embodiment differs from the first embodiment in the location where the battery mounting section 600 is provided. As shown in Figure 11, the battery mounting section 600 in this embodiment is provided on the opposite side of the main frame 100 from the section where the bobbin 700 is provided (i.e., the connecting body holding section 170). By providing the battery mounting section 600 in this position, it becomes possible to easily attach and detach the storage battery unit 60.

[0070] Furthermore, the position of the battery mounting portion 600 may be in a position opposite the connecting body holding portion 170 along the y-direction, as in this embodiment, but it may also be in another position. In other words, the battery mounting portion 600 can be provided at any position on the side surface of the main frame 100 in the -y-direction.

[0071] The third embodiment will be described with reference to Figure 12. Below, we will mainly describe the differences from the first embodiment, and will omit explanations of points common to both embodiments as appropriate.

[0072] In this embodiment, the location of the battery mounting section 600 differs from that of the first embodiment. As shown in Figure 12, the battery mounting section 600 in this embodiment is provided at the upper end of the main frame 100. By providing the battery mounting section 600 in this position, it becomes possible to easily attach and detach the storage battery unit 60.

[0073] In this embodiment, the main frame 100 is not provided with a handle 150. Alternatively, a handle 150 similar to that in the first embodiment may be provided at any position that does not interfere with the battery mounting portion 600.

[0074] The fourth embodiment will be described with reference to Figure 13. Below, we will mainly describe the differences from the first embodiment, and will omit explanations of points common to the first embodiment as appropriate.

[0075] In this embodiment, the location of the battery mounting section 600 differs from that of the first embodiment. As shown in Figure 13, the battery mounting section 600 in this embodiment is located at the -x-direction end of the main frame 100. In other words, the battery mounting section 600 is located at the end of the main frame 100 that is opposite to the end where the clincher 400 is located, along the direction of movement of the driver 30. By providing the battery mounting section 600 in such a location, it becomes possible to easily attach and detach the battery unit 60.

[0076] The fifth embodiment will be described with reference to Figure 14. Below, we will mainly describe the differences from the first embodiment, and will omit explanations of points common to the first embodiment as appropriate.

[0077] In this embodiment, the location of the battery mounting section 600 differs from that of the first embodiment. As shown in Figure 14, the battery mounting section 600 in this embodiment is located opposite the electric motor 50, along a direction perpendicular to both the vertical direction and the direction of movement of the driver (i.e., the y-direction). Specifically, the battery mounting section 600 is located on the -y-direction side of the main body frame 100, in a position opposite the electric motor 50 along the y-direction.

[0078] In this embodiment, the electric motor 50 and the battery unit 60 are aligned along the y-direction, rather than along the x-direction as in the first embodiment. As a result, the overall dimensions of the electric motor 50 and the battery unit 60 along the x-direction are smaller than in the first embodiment. Depending on the arrangement of other components in the binding machine 10 and the constraints of the installation location of the binding machine 10, adopting this configuration may be preferable in some cases.

[0079] In each of the embodiments described above, the strapping machine 10 is positioned and used with the z-direction shown in each figure aligned with the vertical direction. Alternatively, the strapping machine 10 may be positioned and used with the z-direction shown in each figure aligned with the horizontal direction.
