As shown in FIG. 1B, in the bound state, the first leg S10 and the second leg S 20 is a guide element that is engaged with the first object G, and the main body S30, the first leg The second object P can be placed in the area surrounded by the first leg S10 and the second leg S20. .

[0041] As long as an opening is provided for placing the second object P therein, the main body S 30 is formed into various shapes such as a rectangle or a parallelogram according to the shape of the second object P. As shown in FIG. 1A, the main body S30 in this embodiment is It is curved in a C-shape or arc shape so that it opens to the left.

[0042] The first leg S10 and the second leg S20 are portions for engaging with the first object G. As shown in FIG. 1A, the first leg S10 is connected to one end of the main body S30 and is bent. The first portion S101 is bent further from the first portion S101 and extends in the opening direction D1. The first section S101 connects the main body section S30 and the second section S102. is sometimes called the crank section.

[0043] The second leg portion S20 is connected to the other end of the main body portion S30 and has a third leg portion extending in the opening direction D1. and a fourth portion S204 bent outward from the tip of the third portion S203. The fourth portion S204 may be called a hook portion or a tip portion.

[0044] As shown in FIG. 1B, the third portion S203 is bent to be attached to the main body portion S30. The third part S203 is a part that closes the opening formed by the bending. extends in the opening direction D1, i.e., extends substantially parallel to the second portion S102. The third portion S203 is the width of the opening formed by the main body portion, i.e., the width of one end of the main body portion S30. The first portion S102 is formed to be longer than the distance between the first end and the second end, and is formed to be longer than the distance between the first end and the second end. However, when the outer diameter of the first object G is large and the tip of the first leg S10 is spirally wound, When the number of turns is increased when bending the wire into a curved shape (described later), the second part S102 is It may be formed longer than 03.

[0045] The fourth part S204 is a part that engages with the first object G, which is a guide element. The third portion S203 is bent outward from the tip of the third portion S203. The fourth part S204 has elasticity in the direction of widening the opening and returning to its original position. It is possible to apply tension to the first object G in the direction away from the first leg. Therefore, it is possible to prevent the first object G from bending and the staple S0 from falling off. becomes.

[0046] As shown in FIG. 1B, the first leg S10 is displaced to engage with the first object G. The part that is inscribed in the main body S30 has a radius of the largest circle (corresponding to the radius of the second object P in the figure). For example, the distance from the tip of the first leg S10 to this radius (the "first distance") is set as a reference. For example, the following part may be included in the second leg S20: The part to be positioned is determined based on the radius of the largest circle inscribed in the main body S30, for example, The second distance may be a distance of twice this radius from the tip of the nozzle 20 (an example of the "second distance"). By configuring it in this way, it is possible to close the opening using the second leg portion S20. become.

[0047] The shape of the staple S0 is not limited to that shown in FIG. The S10 and the second leg S20 do not necessarily have to be parallel to each other. Even if the opening width becomes narrower or wider as it advances to the tip, The staple S0 can be bent so that at least part of the desired technical effect is achieved. It will be understood by those skilled in the art that the first leg S10 and the second leg S20 have the same length. Although the tip of the first leg S10 is redundant, at least part of the above-mentioned technical effects can be achieved. It will be understood by those skilled in the art that the staple S0 can be bent so that .

[0048] Furthermore, the tip of the second leg portion S20 does not have to be pre-bent like the fourth portion S204. Even if the tip of the second leg S20 is not bent in advance, the second leg S2 0 can be displaced so as to be engageable with the first object G, It will be understood by those skilled in the art that at least some of the effects will be exerted.

A curved surface that is curved so as to be recessed backward in a top view according to the shape of the staple S0 The driver 420 moves forward. When the curved surface contacts the main body S30, the flat surface contacts the crank portion S101. The contact can prevent the crank portion S101 from bending. The portion where the flat surface that contacts the rank portion S101 is provided is called the shoulder portion of the driver 420. Therefore, the curved surface that contacts the main body S30 is formed at the curved portion of the driver 420. It is sometimes called.

[0069] As described above, the binding machine 100 includes the motor 54, a control device for controlling the motor 54, a reducer 55 for increasing the torque of the motor 54; and a ball screw connected to the reducer 55. 50, the ball screw 50 rotates forward or backward, and the ball screw 50 rotates in the direction of the central axis thereof. The driver 420 is provided with a nut part 52 configured to be movable in a certain forward and backward direction. The driver 420 is fixed to the nut 52 by means of bolts or the like. It is configured to be movable in the front-rear direction integrally with the part 52.

[0070] [Crank retention mechanism] The binding machine 100 prevents the crank portion S101 of the staple S0 from being bent. The crank may further include a crank holding mechanism 180 for holding the crank. 4B is a perspective view of the second holding portion 18 of the crank holding mechanism 180 as viewed from the front. 4 is a vertical cross-sectional view through

A first holding portion 182 that supports from the inside (front X1) and a main body that connects to the crank portion S101 and a second holding portion 184 that supports the staple S30 from the inside (right side Y1) of the staple S0. The rearward facing surface of the first holding portion 182 abuts against the front surface of the crank portion S101. The rear surface of the crank portion S101 is a flat surface facing forward of the driver 420. Since the crank portion S101 of the staple S0 abuts against the surface, the crank portion S101 of the staple S0 is It is possible to support the vehicle by clamping it from the inside (from the front and back).

[0072] On the other hand, the surface of the second holding portion 184 facing outward (leftward Y2) is the main body S of the staple S0. The outer surface of the main body S30 is in contact with the inner surface of the driver 42. Since the main body S30 contacts the curved surface of the staple S0, the main body S30 is sandwiched from the outside and inside of the staple S0. In addition to the above configuration, the ceiling surface and the distribution surface of the driver 420 can be The upper surface of the separation block 18 can support the staple S0 from above and below. Therefore, it is possible to support the staple S0 from four directions, top, bottom, left and right. The shape of the bending main body S30 and the crank part S101, which is easily bent by bending, is maintained. It becomes possible to move table S0 forward.

[0073] The crank holding mechanism 180 may be entirely or at least partially composed of a biasing member. For example, the crank holding mechanism 180 may be made of an elastic member and biased backward. By doing so, the first holding portion 182 is pressed against the front surface of the crank portion S101 and supported. This becomes possible.

[0074] The binding machine 100 further includes a mechanism for moving the crank holding mechanism 180 after binding. For example, the crank holding mechanism 180 may be biased rearward and the crank The upper surface of the separation block 18, which the bottom surface of the holding mechanism 180 abuts against, is tilted upward, and the advancing The rank holding mechanism 180 moves upward along the inclined surface, and the staple S0 is clamped. A mechanism may be provided to automatically release the engagement with the link portion S101.

[0075] The crank holding mechanism 180 includes either a first holding portion 182 or a second holding portion 184. It may also be possible to provide only one.

[0076] [First displacement section] The first displacement portion 200 has a function of displacing the first leg portion S10 so as to be engageable with the first object G. do.

[0077] The first displacement unit 200 according to this embodiment moves forward by the driver 420. The tip of the second part S102 of the first leg S10 of the pulley S0 is inserted into the first leg S The tip of the 10 is curved in an arc or spiral shape while proceeding downward. and a groove 211 for guiding the tip of the first leg S10 into the hole 210. Since the hole 210 is provided at the front X1 of the first leg S10, the staple S0 By advancing, the tip of the second part S102 is brought into contact with the inner wall surface of the hole 210, and the second part S102 is moved in accordance with the shape of the inner wall surface. This makes it possible to displace the tip of the second portion S102.

[0078] 5A is a perspective view of the hole 210, and FIGS. 5B and 5C are views showing the guide protrusion 172 in the hole 210. 10. The hole 210 is inserted into the first leg S1. The groove 211, which is the path of travel of the nozzle 0, is formed in the base, and the groove 211 is provided so as to penetrate the base in the vertical direction. In order to make the shape of the staple S0 easier to understand, the first object G is shown in FIG. 5A etc. has been omitted.

[0079] The second part S10 of the first leg S10 is pushed forward by the driver 420. 2 smoothly contacts the cylindrical inner wall surface of the hole 210 from the groove 211. A groove 211 extending in the front-rear direction is formed on the surface of the base so that the first leg S10 can move forward. The groove 211 is formed so that the outer surface thereof is smoothly connected to the cylindrical inner wall surface (when viewed from above). (So ​​that the tangent to the inner wall surface at the connection point between the inner wall surface and the groove coincides with the outer surface of the groove) The hole 210 is formed.

[0080] As shown in FIG. 5A, the base has a hole 210 extending vertically through the base. A guide introduction section 190 is formed, which is connected from the upper end to the lower end. The first object G (FIG. 11, etc.) that will be the guide element, for example, a guide string, is guided through the center of the hole 210. With the first leg S10 positioned along the axis, the tip of the second part S102 of the first leg S10 is inserted into the hole 210. By doing so, the tip of the second part S102 advances in a spiral shape so as to surround the first object G. This allows the first leg S10 to be engaged with the first object G. Since the first object G is inserted into hole 210, hole 210 also functions as a first insertion portion. The inventors of the present application have developed a guide mechanism for guiding the tip of the first leg S10 downward in the Z2 direction. By inserting the protrusion 172 into the hole 210, the second part S102 is promoted to move downward Z2. We focused on the points where we could make progress.

[0081] The guide protrusion 172 is provided with a hole adjacent to the first object G so that the tip of the first leg portion S10 can abut against the hole. 5B and 5C, the guide protrusion 172 is inserted into the second part 210. The further it goes in the direction of rotation of the tip of S102 (counterclockwise in FIG. 5A), the more it protrudes downward. By providing such a configuration, the second part The tip of S102 comes into contact with the inclined surface of the guide protrusion 172 and is guided downward.

[0082] In order to strengthen the engagement between the first object G and the first leg S10, the inner diameter of the inner wall surface of the hole 210 is , it is preferable that the value is less than the sum of twice the wire diameter of the staple S0 and the outer diameter of the first object G. By setting the inner diameter in this way, a part of the first object G or the staple S0 is pressed. Because the staple S0 is crushed, the engagement between the staple S0 and the first object G can be strengthened.

[0083] The inner wall surface formed in the hole 210 does not have to be a cylindrical surface. By forming the inner wall surface of the hole 210 so as to have a circular cross section whose diameter becomes smaller as it goes down, The hole 210 is formed so that the engagement between the first object G and the first leg S10 is strengthened below the hole 210 Z2. Alternatively, the inner wall surface formed in the hole 210 may form a circular hole around the first leg S10. It may also be a curved surface formed in a groove provided in an arc shape for causing arc-shaped displacement.

[0084] Furthermore, as shown in FIG. 5C, the tip of the second portion S102 is turned at least twice (720 degrees or more). The movement of the driver 420 and the formation of the hole 210 are controlled so as to surround the first object G. It is preferable to adjust the position so that the tip of the second part S102 is turned at least twice (720 degrees or more). ) around the first object G, thereby improving the engagement between the first object G and the first leg S10. This makes it possible to strengthen the bond.

[0085] [Lid movement mechanism] The inventors of the present application further proposed a method for closing the hole 210 from above with a lid 170 (FIG. 6). As a result, the tip of the first leg S10 is screwed downward Z2 against the reaction force applied to the first leg S10. We focused on the fact that this can promote spiral progression.

[0086] Therefore, the inventors of the present application came up with the idea of ​​providing a guide protrusion 172 on the lid portion 170, and further By linking the movement of the driver 420 with the up and down movement of the lid portion 170, during the binding operation, The hole 210 is closed by the lid 170, and after binding, the lid 170 rises to open the hole 210. The lid 170 has a hole 210 that is perpendicular to the central axis of the cylindrical surface of the hole 210. The lower surface (bottom surface) facing the hole portion 210 is formed, and by bringing this lower surface close to the hole portion 210, The lid portion 170 closes the hole portion 210, and the lower surface of the lid portion 170 is spaced apart from the hole portion 210. The lid 170 opens the hole 210 .

[0087] The term "closed" means that the hole 210 is closed to prevent the first leg S10 from moving upward Z2. The cover 170 is provided above the hole 210 in the Z1 position. Therefore, a through hole extending in the vertical direction is formed for inserting the first object G to be inserted into the hole portion 210. is formed.

[0088] Hereinafter, the driver 420 will be described with reference to (A) to (D) of FIG. 6 and (A) to (B) of FIG. 7. The structure for linking the movement of the cover 170 with the up and down movement of the cover 170 will be described.

[0089] FIG. 6(A) is a cross-sectional view of the binding machine 100 as seen from the left side.

[0090] As shown in the figure, the binding machine 100 has a driver 420 as a mechanism for moving the lid portion 170. The forward and backward moving part 174 has a path. The path is formed by a first path R1 extending forward and a downward path connected to the front end of the first path R1. and a second path R2 extending in a direction inclined backward, connected to the rear end of the second path R2 and extending backward. The third path R3 extends in a direction inclined upward and forward, and the third path R3 is connected to the rear end of the third path R3. The first path R1 has a fourth path R4 connected to the rear end of the first path R1. The wall is defined by four walls formed in the shape of a parallelogram protruding from the wall.

[0091] However, these four paths do not necessarily have to be parallel to each other. In particular, the second path R2 and the fourth path R4 are not parallel to each other. By changing the inclination angles of the second route R2 and the fourth route R4, Therefore, the route lengths of the second route R2 and the fourth route R4 can be changed. By changing the angle of the path R4, the timing at which the lid part 170 is raised and lowered can be changed. This makes it possible to:

[0092] The lid 170 closes the hole 210 when or just before the tip of the first leg S10 reaches the hole 210. It is preferable to move 210 downward to close it.

[0093] The crank holding mechanism 180 also holds the crank before the push-out member 250 (described later) moves upward Z1. It is preferable that the engagement with the rank portion S101 is automatically released.

[0094] In this embodiment, when the tip of the first leg S10 reaches the hole 210, the cover 1 70 has completed the operation of closing the hole 210, and the engagement with the crank portion S101 has automatically After the helical portion is dynamically released, the pushing member 250 (described later) moves upward Z1 to eject the helical portion. The inclination angles of the second path R2 and the fourth path R4 are made different from each other so that It is composed of:

[0095] Furthermore, the moving mechanism includes a pin 176 that moves along a path and a link 178 fixed to the pin 176. 78 and two shaft portions that restrict the movement of the link 178 in the front-rear direction.

[0096] The pin 176 is formed, for example, in a cylindrical shape that protrudes to the left Y2, and is formed in a parallelogram shape. The nozzle is configured to travel along the four wall surfaces of the formed wall portion.

[0097] The link 178 is provided to extend in the front-rear direction, and is attached at its front end to one of the first shaft portions 186. The rear end of the shaft 188 engages with the other second shaft 188. Since the link 178 is fixed to the main body of the binding machine 100, it can be moved forward and backward by two shafts. Movement is restricted.

[0098] Furthermore, the movement mechanism includes a vertical movement part 192 that engages with the two shaft parts, and a vertical movement part 192 and The movement mechanism has a plurality of elastic members inserted between the pin 176 and the link 178. When the link 178 moves up and down as the lever moves downward, the elastic member is pushed by the link 178. The vertically movable part 192 is configured to move up and down based on the change in elastic force generated by the Since the lid 170 is connected to the vertically moving part 192, the pin 176 It is possible to link the vertical movement of the pin 176 with the vertical movement of the lid 170. It is linked to the forward and backward moving part 174 which moves in conjunction with the driver 420. It is possible to link the movement of the lever 420 with the up and down movement of the lid portion 170.

[0099] FIG. 6A shows the position of the pin 176 in the initial state. The nozzle 176 is positioned on the second path R2. At this time, the lid 170 closes the hole 210. There are.

[0100] FIG. 6B shows the position of the pin 176 after the initial state when the driver 420 is moving forward. The driver 420 and the forward / backward moving part 174 are configured to move in conjunction with each other, More specifically, as the driver 420 moves forward, the forward / backward moving part 174 moves with a time lag. The driver 420 moves forward with a delay, and the forward / backward moving part 174 moves backward with a delay. and moves backward.

[0101] When the driver 420 advances, the forward and backward moving part 174 advances, and the part 174 tilts. The pin 176 located on the second path R2 moves downward Z2 along the second path R2. When the pin 176 moves downward, the link 178 also moves downward.

[0102] The first shaft portion 186 is connected to the link 178 and the vertically moving part 192 below the link 178. In addition, a disc spring, which is an elastic member, is provided between the link 178 and the vertically moving part 192. The spring 194 is inserted so that the first shaft portion 186 passes through it.

[0103] Therefore, as shown in FIG. 6(B), when the link 178 descends, the disc spring 194 is compressed. As a result, the force pushing the vertically moving part 192 downward in the Z2 direction increases. The lid portion 170 connected to the hole 210 is pushed downward Z2 with a strong force so as to close the hole 210. The hole 210 is pressed by the staple S0. The tip of the first leg S10 of the staple S0 is inserted into the hole 210. Since the first leg S10 is inserted (or is about to be inserted), the lid 170 is The tip is guided to advance downwards to Z2.

[0104] With the above-described configuration, when the driver 420 advances, the cover portion 170 is pushed downward in the Z2 direction. Therefore, while the pin 176 is descending on the second path R2, the lid portion 17 0 descends, making it possible to close the hole 210 with a strong force.

[0105] As shown in FIGS. 6B and 6C, a driver 420 and a front-rear moving part 17 While the pin 176 is moving forward, the pin 176 moves along the third path R3. Therefore, when the pin 176 is on the third path R3 during the binding operation, By configuring the hole 210 to be present, a lid is inserted to close the hole 210 during the bundling operation. Therefore, it is possible to realize a mechanism for continuously pressing the hole portion 210 downward Z2 by the portion 170. do.

[0106] As shown in FIG. 6C, when the driver 420 and the forward / backward moving part 174 are at their most advanced positions, When this occurs, the pin 176 transitions from the third path R3 to the fourth path R4. The fourth path R4 extends upward Z1 and Since the disc spring 194 extends in a direction inclined forward X1, the elastic force of the disc spring 194 78 and the pin 176 move upward. By inserting an elastic member between the upper link 178 and the lower vertically moving part 192, This allows the lid portion 170 to be moved up and down in a well-balanced manner.

[0107] FIG. 6(D) shows the state when the driver 420 has completed moving forward, and FIG. 7(A) shows the state when the driver As shown in these figures, the driver 420 is in the retracting position. When the forward movement of the pin 176 is completed and the rearward movement of the pin 176 is started, the pin 176 moves upward along the fourth path R4. As the pin 176 moves to the fourth path R4, the disc spring 194 begins to compress. Therefore, the pin 176 moves upward Z1 as shown in FIG. When the vertically moving part 192 moves, the vertically moving part 192 and the cover part 170 move upward in the Z1 direction. The blockage of the hole 210 by the first leg S10 is released, and the hole 210 is opened. The engaged first object G can be removed from the binding machine 100. In order to facilitate the upward movement of the 92 in the Z1 direction, the first shaft portion 186 and the second shaft portion 188 are provided with vertical movement members. It is preferable that an elastic member is inserted in each of the movable parts 192 to push the movable part 192 upward Z1. With this configuration, when the elastic force due to the compression of the disc spring 194 weakens, the vertical movement It is possible to smoothly push up the part 192 in the upward Z1 direction. The elastic portion for pushing up the upper Z1 is provided in a portion other than the first shaft portion 186 and the second shaft portion 188. A material may be provided.

[0108] FIG. 7(B) shows the state just before the driver 420 has completed the retreat. As shown in FIG. 7B, the driver 420 and the forward / backward moving part 174 are moved backward. During this time, the pin 176 is maintained in an upper position where the first path R1 is provided. While the driver 420 is returning to the initial state after the lift-off, the cover 170 is lifted upward Z1. It is possible to realize a mechanism that

[0109] Thereafter, when the pin 176 moves from the first path R1 to the second path R2, the lid portion 170 descends. The hole 210 is closed with a weak force.

[0110] With the above-described configuration, the first leg of the staple S0 is lowered during the bundling operation. S10 is displaced downward Z2 to engage with the first object G, and then rises after binding is completed. This allows the first object G engaged with the first leg portion S10 of the staple S0 to be removed. This makes it possible to realize a configuration of the lid portion 170 that achieves this.

[0111] [First object holding mechanism] Hereinafter, the guide holding mechanism 23 for holding the first object G in a state where it is inserted into the hole 210 will be referred to as a guide holding mechanism 23. The hole 210 is called an insertion part because the first object G is inserted into the hole 210. FIG. 8 is a perspective view of the guide holding mechanism 230. As shown in the figure, The guide holding mechanism 230 is formed in a plate shape, and the guide holding mechanism 230 has a guide holder. A through hole that passes through the holding mechanism 230 from top to bottom, and a through hole that connects the outer periphery of the guide holding mechanism 230 The through-hole has a notch for passing through the first object G in order to suitably hold the first object G. The through hole has an inner diameter that is equal to or smaller than the outer diameter of the first object G. The through hole has a central axis and It is preferable that the central axis of the hole 210 is substantially aligned with the central axis of the hole 210 when viewed from above. When the first object G is held by the guide holding mechanism 230 with this configuration, G can be easily positioned on the central axis of the hole 210. They may be provided above and below the hole 210, or may be provided on only one side.

[0112] Furthermore, the guide holding mechanism 230 may be provided as part of the lid portion 170. By providing the mechanism 230 as a part of the lid portion 170, the mechanism 230 moves in conjunction with the movement of the driver 420. This allows the guide holding mechanism 230 to be moved up and down. The inner diameter of the through hole is formed smaller than the inner diameter of the hole portion 210, thereby This allows a part of the area of ​​the hole 210 to be blocked except for the center of the hole 210. The first object G is placed at the center, and the second leg S20 moves around the periphery of the first object G. By closing a part of the area except for the center of the hole 210 with the guide holding mechanism 230, , the first leg S10 is pressed downward against the reaction force received by the first leg S10, and the first leg S1 It is now possible to move the tip of 0 in a spiral.

[0113] Furthermore, by providing a guide protrusion 172 on the underside of the guide holding mechanism 230, the first leg S It is possible to guide the downward progression of the tip of 10.

[0114] [Second displacement section] The second displacement portion 300 has a function of displacing the second leg portion S20 so as to be engageable with the first object G. do.

[0115] As the driver 420 moves in the opening direction, the second displacement portion 300 moves the second leg portion S20 The second leg portion S20 is configured to be displaceable inward of the staple S0. The loop S0 is configured to be plastically deformable so as to be curved inward in an arc shape.

[0116] Specifically, as shown in FIG. 9(A) described later, the second displacement portion is The opening direction D1 is called the forward X1 because it coincides with the opening direction D1 (forward X1). The second leg S20 of the staple S0 moving in the same direction as the first leg S20 abuts against the second leg S The first guide wall 312 curves the stay 20. The recess 312A is recessed outward (to the right Y1) of the pull S0. A is provided outside the second leg S20 in the initial state, and the distance between A and the second leg S20 is a first recessed area having a wall surface that increases in size as the user moves toward the first recessed area; and a second leg connected to the first recessed area. a second recessed area having a wall surface whose distance to the recessed area S20 decreases as the recessed area moves forward; .

[0117] Furthermore, the second displacement portion 300 (FIG. 9(A), etc.) has a second leg S The second leg S20 of the staple S0 is provided at the front X1 of the stapler 20 and moves in the opening direction D1. The second guide wall 320 is in contact with the second leg portion S20 to bend the second leg portion S20. The wall 320 is provided with a wall surface facing the rear X2. The protrusion 320A protrudes in the direction X2. In the initial state, the protrusion 320A is The second leg S20 is provided in front of the second leg S20 in the front-rear direction and is located in front of the second leg S20 in the left-right direction. The further to the left Y2 (the inner side of the staple S0), the further to the rear X2. In other words, the height from the second guide wall 320 in a top view is increased. The protrusion 320A is a protrusion that becomes thinner.

[0118] The inventors of the present application have found that the provision of the protrusion 320A is more effective than the provision of the protrusion 320A. By doing so, the second leg S20 is smoothly curved so as to proceed toward the first leg S10. We focused on the fact that it is possible to do this.

[0119] [Binding method using a binding machine] The bundling method using the bundling machine 100 will be described below. The first object G to be inserted into the recess (second insertion portion) formed in the separation block 18. 2. The object P is omitted from the drawing for the sake of convenience. It may be omitted.

[0120] 9(A) to (C) and 10(A) to (D) show the process of staking using the binding machine 100. 10 is a cross-sectional view from above showing the process of engaging the loop S0 with the first object G.

[0121] As shown in FIG. 9A, the driver 420 moves forward, and the driver 4 The staple S0 is pushed forward by the crank holder 20 and moves forward. The mechanism 180 supports the crank portion S101 of the staple S0, thereby Prevents 101 from bending.

[0122] As shown in FIG. 9(B), a second guide wall 320 is provided at the front X1 of the second leg S20. Therefore, the hook portion S204 of the second leg portion S20 is located at the rear X of the second guide wall 320. 2 and travels along the wall surface 320B of the second guide wall 320.

[0123] The wall surface 320B of the second guide wall 320 faces rearward X2 and is formed generally parallel to the left-right direction. Since the hook portion S204 has a portion that is in contact with the hook portion S204, the hook portion S204 cannot advance forward in the X1 direction (or The amount of movement of the hook portion 240 in the forward direction X1 is the amount of movement of the main body portion S30 of the staple S0 in the forward direction X1. Therefore, the third part S203, which is moving forward to X1, is curved.

[0124] On the other hand, the first guide wall 312 is disposed outside (to the right Y1) the second leg portion S20. The first guide wall 312 is shaped so as to face inward of the staple S0 and be recessed outward (to the right Y1). The recess 312A includes a recessed surface 312A1 formed therein.

[0125] Therefore, as shown in FIG. 9C, the third portion S203 is formed on the concave surface 312A of the recess 312A. 1 and curves outward.

[0126] During the advancement of the driver 420, the pin 176 advances along the third path R3. 0 closes the hole 210 downward Z2 with a relatively strong force.

[0127] As shown in FIG. 9A, the second guide wall 320 becomes gradually narrower as it advances inward (to the left Y2). The hook portion S204 includes a protrusion 320A that increases the amount of protrusion toward the rear X2. 9B and 9C, the slit 320 moves backward in the X2 direction while contacting the protrusion 320A. At this time, the driver 420 is further forward, so the third part S20 3 further contacts the concave surface 312A1 of the deflection recess 312A and moves outward along the shape of the concave surface 312A1. It curves so that it bulges out greatly in the direction of the arrow.

[0128] As shown in FIGS. 10(A) and 10(B), the hook portion S204 rests on the second guide wall 320. When climbing over the obstacle, the hook portion S204 advances forward in the X1 direction due to the elasticity of the second leg portion S2. The third portion S203 of the portion S2 abuts against the protrusion 320A.

[0129] Through the above process, the second leg S2 moves in the first direction, which corresponds to the clockwise direction on the paper. The displacement is such that the curve is curved in the rotation direction R1.

[0130] By providing the second guide wall 320, the hook of the staple S0 moving in the forward direction X1 is The portion S204 can be moved in a direction toward the inside of the staple S0. The first guide wall 312 is provided with a recess 312A having an outwardly recessed surface 312A1. This makes it possible to promote bending of the second leg portion S20.

[0131] Furthermore, by providing a protrusion 320A and abutting the hook portion S204 and the third portion S203, , the hook portion S204 is moved in the direction toward the first object G compared to when the protrusion 320A is not provided. It is now possible to precisely control and displace the object.

[0132] After the hook portion S204 has climbed over the second guide wall 320, the tip of the first leg portion S10 The first displacement portion 200 starts to enter the hole portion 210. After the maximum load due to the displacement of the second leg portion S20 is applied, the first leg portion S20 is displaced by the first displacement portion 200. By configuring the binding machine 10 so that the maximum load due to the displacement of the section S10 is applied, This makes it possible to prevent a large load from being placed on 0.

[0133] As described above, the first displacement portion 200 moves the staple S0 in the opening direction D1, for example. When the staple S0 is pressed against the first object G, the distal end of the first leg S10 of the staple S0 is guided by the first object G. The first object G is formed so as to surround the outer periphery or to proceed in a spiral around the outer periphery of the first object G. The staple S0 can be configured with a hole 210. The staple S0 has flexibility and plasticity. Therefore, when the staple S0 moves in the opening direction D1, the tip of the first leg S10 forms a spiral. The spiral advances along the inner wall of the hole 210 while drawing and curving. By moving the staple S0 forward with the first object G placed thereon, the first object G is rotated in a axial direction. The distal end of the first leg S10 of the staple S0 is fastened in a spiral shape around the outer periphery of the first object G. It is possible to combine them.

[0134] At this time, the pin 176 is moving along the third path R3, so it is provided on the cover portion 170 and protrudes downward. The guide protrusion 172 that protrudes enters the inside of the hole 210 as the cover part 170 descends, and the first leg part S The cover 170 presses the first leg S10 downward, Therefore, the tip of the first leg S10 is caused to advance in a spiral shape against the reaction force received by the first leg S10. This makes it possible to:

[0135] When the driver 420 further advances the staple S0, the hook portion S204 The guide wall 232 contacts the inclined surface 232A and moves upward Z1. As shown, the hook portion S204 is connected to the first object G inserted into the hole 210 and the separation block. The second object P is inserted into the recess of the lock 18, and when viewed from above, The second leg S20 including the hook portion S204 advances to a position where it intersects with the first leg S10. As a result of contacting the inclined surface 232A, the surface moves upward in the Z1 direction. At this time, the second leg portion S20 or the main body portion S30 is displaced above the second guide wall 320 in the direction Z1.

[0136] Fig. 10(D) shows the state where the driver 420 is retracted after bundling. As the staple S0 is retracted, the staple S0 exerts elastic force to restore its original shape. S20 is displaced in a second rotation direction R2, which is the opposite direction of the first rotation direction R1, and rotates toward the first object G.
