Description

  The present invention relates to a bundling tool for positioning a bundling tool used for bundling a binding object such as an electric wire with a bundling band at a planned bundling position in the bundling object and mounting the bundling band on the bundling object with high dimensional accuracy. The present invention relates to a positioning structure and a bundle positioning method.

  There are various binding objects, such as an electric wire group, a pipe group, and various long products. Typical examples include wire harnesses frequently used in vehicles such as automobiles, construction machines, and work machines. With respect to bundling a wire harness composed of a large number of electric wire groups with a bundling band at an appropriate interval, those disclosed in Patent Document 1 and Patent Document 2 are known. In these Patent Documents 1 and 2, by using a binding jig (harness stand) having a substantially U-shaped wire harness receiving portion, means for supporting the wire harness in a suspended state above the support substrate It is shown.

By promoting the mechanization of the bundling work using the bundling tool in this way, there is an advantage that the bundling work at a large number of places can be performed efficiently and with less labor burden.

  In wire harnesses used for automobiles and the like, a binding band in which a mounting portion (clamp portion) for a vehicle body panel is integrated has been increasingly used in order to simplify assembly when mounting on a vehicle body. . Specifically, a specialized maker that manufactures wire harnesses, using a “clamping band with clamps” in which a clamping part for fitting and fixing in a mounting hole formed in a vehicle body panel is previously formed integrally with a banding band. Will deliver wire harnesses bundled with a number of binding bands with clamps to an automobile manufacturer. Therefore, in order to smoothly mount a large number of clamp portions in the corresponding mounting holes of the vehicle body panel, it is required to bind the binding band with clamps to the wire harness with high dimensional accuracy.

  In recent years, wire harnesses, which have a tendency to increase the number of electric wires due to computerization, tend to increase the rigidity of the wire harness, and the rigidity is further increased by being bound at an appropriate interval. Therefore, because of its high rigidity, the flexibility of shifting the position of the binding band with clamp after binding is difficult, so if there is an error in the relative position between the clamp part of the binding band and the mounting hole, the clamp part is attached to the mounting hole. There is a problem that cannot be inserted. In this case, the binding band must be removed by cutting or the like and replaced with a new binding band at the site, which is very cumbersome and inefficient. Therefore, in order to avoid such an inconvenience, the relative dimensional accuracy between the mounting hole for inserting the clamp formed in the body panel in advance and the binding band provided in the wire harness is increased, that is, the binding band is It has been required to bind the wire harness to the planned binding position with higher accuracy.

However, in the structure and device related to binding the wire harness shown in Patent Document 2 described above with a binding band, the invention is not limited to disclosing a jig for installing the wire harness, that is, a binding jig, There is no particular description regarding the positioning of the binding tool. Therefore, the bundling tool can only be positioned by human operation, and the bundling tool positioning means that relies on such human operation cannot satisfy the above-mentioned requirements regarding high dimensional accuracy.

Further, as shown in FIG. 5, the ratchet gear 22 is provided as long as no external force is applied by a torsion spring 54 fitted to a stepped pivot pin 53 for pivotally connecting the swing arm 19 and the connection link 24. Is pivoted in the direction of arrow E (see FIG. 4) about the pivot axis p4 with the connecting link 24 as a center. Both ends of the torsion spring 54 are engaged with the third link plates 19a of the swing arm 19, and the center portion is hooked and engaged with a receiving pin 23b protruding from the base end portion 23A.

  Next, the operation of the one-way clutch Cr will be described. The operation lever 18 is swung in a direction in which the base end side 18A is raised, and the ratchet pawl is moved via the operation link 25, the swing arm 19, and the connection link 24. 23 moves toward the tip 18B side (the left side in FIG. 4), the claw 23a moves into the trough 22B of the ratchet gear 22 to move the tooth 22A (the stop surface 22b). ) And the ratchet gear 22 rotates and moves in the direction of the arrow c. That is, the clutch is engaged with the ratchet pawl 23 and the ratchet gear 22 moving together. When the operation lever 18 is moved downward and the ratchet claw 23 moves toward the band holder 14 side (the right side in FIG. 4), the claw portion 23a rides on the inclined surface 22a and slides. Thus, the ratchet pawl 23 is moved to the band holder 14 side, but the ratchet gear 22 does not rotate. That is, the clutch is disengaged in which only the ratchet pawl 23 is moved.

  With the above structure, if the operating lever 18 is swung upward, the operating link 25 pushes the ratchet pawl 23 via the swing arm 19 and the connecting link 24, and the pawl portion 23a is engaged with the ratchet gear 22. The tension gear 21 is pivotally moved in the direction of the arrow C, and the band portion 1 meshing with the gear portion 21a is pulled toward the front side, whereby the planned binding portion n in the wire harness W is tightened. The swinging range of the operation lever 18 related to the tightening operation for pulling the band portion 1 is the operation at the standby position T from the standby position T (see FIG. 1) where the operation lever 18 comes into contact with the stop end 6t of the tool body 6 and stops. When the lever 18 is gripped with fingers gripping the grip portion 6a, the left and right end portions of the connecting pin 26 penetrating the elongated hole 18a to pivotally connect the base end portion of the operating link 25 to the operating lever 18 are formed on the tool body 6. This is a position until it comes into contact with the bottom surface of the stopper member 27 made of a plate material screwed to the left and right inside, that is, until a tightening position H (see FIG. 9).

  As shown in FIGS. 1 and 3, the operation portion b is configured by disposing the operation lever 18 pivoted at the main fulcrum X in a state where the base end portion 18 </ b> A is positioned below the grip portion 6 a. . The operation lever 18 is configured to return itself to a standby position T where the bottom wall 29 of the base end portion 18A abuts against the stop end 6t of the tool body 6 by a return spring 28 that pulls on the distal end portion 18B. The tip 18B is a part that functions as a member for operating the cutting mechanism d using the pin roller 18b supported at the tip. A pair of left and right peep holes 18d for internal confirmation are formed at the base end portion 18A of the operation lever 18.

  As shown in FIGS. 1 to 6, the push-out mechanism c includes a housing 30 that is screwed to the outer surface of the tool body 6, a rack gear 31 that is accommodated in the housing 30, an operation gear 32 that is rotatable at the main fulcrum X, The lock release plate 33 fitted to the boss portion 32a of the operation gear 32, the composite rotator 17 linked to the operation gear 32 via a one-way clutch 34 (see FIG. 21), and the state in which the composite rotator 17 is housed. The one-way clutch 34 and the like. The housing 30 accommodates a rack gear 31 that is a long member so as to be slidable back and forth, and covers the operation gear 32 and the lock release plate 33. A housing 39 for sliding the rack gear 31 with fingers is externally provided. A long notch 30a for projecting is formed. Reference numeral 40 denotes a leaf spring that exerts a stopper function that restricts the unexpected movement of the rack gear 31 and also provides a light frictional resistance when the rack gear 31 is slid by a finger to provide a sense of moderation.

  As shown in FIG. 21, the one-way clutch 34 is rotatable at a main fulcrum X in the inner space 17S and the clutch pawl 35 pivotally supported by the first axis p1 in the inner space 17S of the composite rotator 17. A clutch gear 37 pivotally supported by a pair of circular cover plates 36, 36, and a torsion spring 38 that presses and urges the clutch pawl 35 toward the inner diameter side. Each cover plate 36 is screwed to the left and right of the composite rotating body 17 so as to be a lid that covers the internal space 17S. The operation gear 33 and the clutch gear 37 are interlocked and connected in an integrally rotated state by a key shaft 41 (see FIG. 4) fitted over both of them.

  Now, this pushing mechanism c has a function of pushing a set amount of the band portion 1 drawn below the tension gear 21 by grasping the knob 39 with a finger and sliding it to the tip side. The detailed operation status is as follows. That is, when gripping the knob 39 at the return position m (see FIG. 1) and starting to slide forward, first, an action stage that is integrally formed inside the rack gear 31 and has a tip-down approach curved surface 31a at the tip. The lock release plate 33 rides on the portion 31A and moves in the vertical direction with respect to the tool body 6. The tip 33a pushes up the receiving pin 23b projecting laterally at the tip of the ratchet claw 23, and the claw 23a. And the ratchet gear 22 are disengaged, and a state in which the composite rotating body 17 is rotatable in the direction of the arrow D is brought about (see FIG. 5).

  At substantially the same time as the ratchet pawl 23 is lifted and swung, the tooth portion 31b of the rack gear 31 and the tooth portion 32b of the operation gear 32 start to engage with each other, and the rotation of the composite rotating body 17 in the two arrow directions is started. The band part 1 engaged with the gear 21 is forcibly pushed out. Then, as shown in FIG. 6, the band portion 1 is pushed out and held by the tip holding portion 5 when the rack gear 31 is slid to the pushing position k where the knob 39 is located at the foremost end of the long notch 30 a. A state of projecting a set amount from the head portion 2 is obtained. Thereafter, the knob 39 at the push-out position k is slid forward to return the rack gear 31 to the return position m. During this return slide movement, the operation gear 32 and the clutch gear 37 are moved by the function of the one-way clutch 34. The composite rotating body 17 does not rotate back due to idling, so that the extruded band portion 1 is not pulled back.

  In this way, by installing the one-way clutch Cr in the tension gear 21 that is a component for the tightening mechanism a, the component for the extrusion mechanism c that rotates in the direction opposite to that during the operation of the tightening mechanism a. A rational and economical configuration that can also be used as a (rotating body for extrusion) is possible, and the engagement portion 104K of the band portion 1 and the tension gear 21 can always be engaged with each other. There is an advantage that there is no risk of damage to the locking portion 104K such that the peak portion 104b is crushed due to incompleteness or the like. For example, in the structure disclosed in the above-mentioned Patent Document 1, the structure is such that when the lever is gripped, the band is engaged and pulled, and when the lever is released, the engagement with the band is also released. There is a possibility that the band part is pushed and pulled when switching between occlusion and detachment, and the locking part of the band part may be crushed, and the subsequent engagement with the head part may become unstable. On the other hand, in the bundling and tightening tool of the present invention employing the constantly meshing structure of the band portion 1 and the tension gear 21, such a fear does not occur, and a reliable engagement state between the band portion and the head portion is realized. Thus, the advantage that the good reliability of the binding band can be maintained is obtained.

  As shown in FIGS. 3, 7, 11, and 18, the cutting mechanism d is basically a cutter blade 15 that is supported slidably back and forth by a tip holding portion 5 formed of a synthetic resin material or the like, It is comprised from the L-shaped arm 16 which has the front-end | tip part 16a which carries out uneven | corrugated engagement with the cutter blade 15. As shown in FIG. The cutter blade 15 is made of a stainless steel plate formed with a tip blade portion 15a and an operation hole 15b for passing the tip portion 16a. The cutter blade 15 accommodates the recessed hole portion (head portion 2) of the tip holding portion 5. When the L-arm 16 is in the set position g, the cutter blade 15 is in the standby position. When the L-shaped arm 16 swings and moves to the operating position q, the cutter blade 15 moves forward, and the band portion 1 is cut at a position immediately before the head portion 2.

  The L-shaped arm 16 is a part formed in a bifurcated shape in which an intermediate portion including the fulcrum Z branches into the left and right arm portions 16A and 16B so as to straddle the rail guide 42 forming the guide passage 20. It is pivotally supported by fulcrum Z. The rail guide 42 is an independent part that is formed by a pair of left and right halves 42A and 42B and is screwed to the body tip 6b, and a curved partial guide path 42R that follows the guide passage 20 is formed inside. ing. The left and right arm portions 16A and 16B are configured to be swingable in the space between the inner surface of the tool body 6 and the rail guide 42.

  As shown in FIG. 18, the structure portion 12 for supporting the cutter blade 15 in a slidable manner has a length for receiving the insertion hole 57 a for inserting the band portion 1 and the distal end portion 16 a of the L-shaped arm 16. In order to avoid interference between the metal-made cutter holder 57 in which the hole 57b is formed, the sliding plate 58 placed on the head holder 55, and the tip portion 16a of the L-shaped arm 16, the head holder 55 is moved downward. It is composed of a relief groove 55N formed to be recessed. The head holder 55 and the cutter holder 57 are screwed to the body tip portion 6b from the side. In other words, the cutter blade 15 is slidably moved back and forth in a hollow trunk formed between the upper and lower sides of the sliding plate 58 and the cutter holder 57, and slides forward or backward as the L-shaped arm 16 swings. Moved.

  The sliding plate 58 is formed with an insertion hole 58a for inserting the band part and an operation hole 58b for passing the tip part 16a. The pair of guide pieces 58g, 58g with a pair of guide pieces 58g of the sliding plate 58 is formed to a size that allows only one band portion 1 to pass through, and is wound around the binding target to be the head portion 2. It is configured to function as a band stopper that receives the band portion tip 1t reinserted into the tool body and prevents it from proceeding further into the tool body 6. Accordingly, the band portion 1 re-inserted into the head portion 2 stops before reaching the cutter blade 15, and only one band portion 1 can be cut by the cutter blade 15.

  In the cutting mechanism d, as shown in FIG. 11, the pin / roller at the tip of the lever is moved by further swinging the operating lever 18 at the tightening position H and swinging it to the cutting position S (see FIG. 10). 18b pushes down the base end portion of the L-shaped arm 16, whereby the L-shaped arm 16 swings in the direction of the arrow (see FIG. 11), and the cutter blade 15 moves forward and moves. When the cutter blade 15 slides in the forward direction, the band portion 1 that comes out from the tip of the guide passage 20 and is supplied to the head holder 55 through the cutter holder 57 and the sliding plate 58 can be cut. Then, the operation of the cutting mechanism d is configured to be automatically performed when the set bundling pressure defined by the bundling pressure setting mechanism e described later is reached and the tightening of the band portion 1 is finished. Yes.

  When the binding pressure (tightening pressure) due to tightening of the band portion 1 reaches a set value, the binding pressure setting mechanism e further increases the operating lever 18 from the tightening position H while preventing the tightening mechanism a from further operating. This is a mechanism that exhibits the function of allowing the upward swing (the function of cutting the band portion 1). As shown in FIGS. 3, 7 to 10, and FIG. 20, in the internal space of the base end portion 18A of the operation lever 18. It is configured. On the upper surface of the bottom wall 29 of the base end portion 18A having an upward U-shaped cross section, a slider 45 made of aluminum alloy and having a downward U-shaped cross section is bolted via a sliding plate 44 made of stainless steel. A tension adjuster 46 made of a sheet metal is arranged so as to be slidable back and forth so as to straddle the slider. The tension adjuster 46 is attached to the operation lever 18 by a bolt 47, a double nut 48, and a coil spring 49 that pass through the base end wall 46a and the folded wall 18c formed on the base end side of the base end portion 18A. On the other hand, it is urged toward the front (rear) side, that is, toward the band holder 14 side.

  A triangular plate 51 is pivotally connected to the front end portion of the tension adjuster 46 by a third axis p3 facing left and right, and this triangular plate 51 is a second axis facing right and left that is located immediately above the third axis p3. It is pivotally supported by the base end portion 18A of the operation lever 18 at p2. On the upper side 51A of the triangular plate 51, there is formed a substantially semicircular recess 51a for inserting and pushing the roller 50 fitted on the connecting pin 26 of the operating link 25. Usually, the recess 51a is formed in the recess 51a. The roller 50 is maintained in a state where it is lowered. Due to the elasticity of the coil spring 49, the tension adjuster 46 is urged to return so that the base end wall 46a abuts against the folded wall 18c. Usually, the connecting pin 26 is positioned at the front end of the long hole 18a, and the roller 50 Is in a state of fitting into the recessed portion 51a (see FIGS. 7 and 8).

  The operation of the binding pressure setting mechanism e will be described. In the range where the bundling pressure is less than or equal to the set value, in the swinging operation of the operating lever 18 from the standby position T (see FIG. 1) to the tightening position H (see FIG. 9), a triangular plate that swings integrally with the operating lever 18. 51 pushes the operating link 25 via the roller 50 fitted in the recessed portion 51a, whereby the tightening mechanism a is operated and the band portion 1 is tightened. When the operating lever 18 swings back from the tightening position H to the standby position T, the one-way clutch Cr is in an inoperative state so that the composite rotating body 17 does not move, and the link portion including the swing arm 19 and the operating link 25 is provided. Moves back.

  When the bundling pressure (tightening pressure) reaches a set value by one or more ascending / descending operations of the operation lever 18, as an example, as shown in FIG. When the bundling pressure reaches the set value at the intermediate position between the tightening position H and the tightening position H, the reaction force that the operating link 25 pushes the triangular plate 51 downward about the second axis p2 via the roller 50 causes the coil spring 49 to be tensioned. By pressing the adjuster 46, the triangular plate 51 is lifted upward about the second axis p2 and the urging force to swing is overcome (until then, the urging force has prevailed over the reaction force). When the operating lever 18 is continuously swung up and down, the connecting pin 26 fitted in the long hole 18a cannot move downward, and as a result, the triangular plate 51 swings and moves downward about the second axis p2. Thus, the roller 50 is relatively removed from the recessed portion 51a, whereby the connecting pin 26 is in a state where it can freely move to the front end (the band holder 14 side) in the long hole 18a. Then, the composite rotating body 17 is rotated back in the direction of the arrow D (see FIG. 4) by the tension force of the band portion 1 which is strongly tightened, and thereby the long hole of the base end portion 18A of the connecting pin 26 is obtained. It moves backward to the foremost side in 18a.

  Along with the backward movement of the connecting pin 26 while the upper side 51A is in contact with the roller 50, both end portions of the connecting pin 26 and the stopper fitting 27 are not in contact with each other. It is possible to make the rocker lift further than H. Therefore, as shown in FIG. 10, the operation lever 18 can be lifted and swung beyond the tightening position H by continuing the operation of gripping and tightening the operation lever 18 that is gripped together with the grip portion 6a. The pin roller 18b at the tip of 18 pushes down the base end portion of the L-shaped arm 16 to operate the cutting mechanism d, and the band portion 1 is cut. At this time, the coil spring 49 is in a slightly compressed state, whereby the proximal end wall 46a is in a positional relationship slightly away from the folded wall 18c. While the operating lever 18 is moved upward and swinging from the swinging operation position (for example, the position of FIG. 8) at which the binding pressure reaches the set value to the cutting position S, the operating link 25 is not pushed and the tightening mechanism a Is in a state in which it operates idle, and the band portion 1 is cut in a state where the set binding pressure is maintained.

  That is, the bundling pressure setting mechanism e is configured to automatically operate by a change in the balance between the bundling pressure increased by the operation of the tightening mechanism a and the coil spring 49, so that the operator can grasp the grip portion 6a of the operating lever 18. Convenient that both the tightening operation to the set bundling pressure of the band portion 1 and the cutting operation of the band portion 1 can be carried out alone by performing the swinging operation by grasping in the state of co-grip with one or more times. It has become. Further, by adjusting the initial stress by operating the double nut 48 and changing the set length of the coil spring 49, the binding pressure can be increased or decreased arbitrarily. The double nut 48 includes a guide nut 48A (see FIG. 20) with a guide function in which left and right end portions 48a are inserted into guide long holes 46b formed in the left and right side walls of the tension adjuster 46, and a general hexagon nut 48B. And is a main component for causing the binding pressure adjusting mechanism e to function.

  By the way, in a state where the binding pressure reaches the set value and the operating lever 18 can be further swung up from the tightening position H, that is, in a state where the connecting pin 26 moves from the front end to the rear end of the elongated hole 18a of the lever base end portion 18A. The tension gear 21 (the composite rotating body 17) may be rotated in the direction of the arrow D (see FIG. 4) by the elastic reaction force of the band part 1 that is strongly tightened. There is. For example, in a binding tightening tool having a structure that is cut while continuing to tighten the band portion, the band portion 1 is strongly pulled and slightly extended in the state of the set binding pressure. The engagement between 104K (mountain portion 104b) and the second engagement piece 111 of the head portion 2 may be uncertain. Then, when the band portion 1 is cut at a position close to the head portion 2 in that state, the locking portion 104K that should be engaged with the second engagement piece 111 is not engaged, and the next locking portion. There is a possibility that 104K is engaged and the excessive band portion 1 is extremely reduced, or in some cases, the engagement is impossible.

  On the other hand, in the binding and tightening tool A according to the present invention, while the connecting pin 26 moves from the front end to the rear end of the long hole 18a of the lever base end portion 18A, that is, for a moment immediately before the band portion 1 is cut. Since the composite rotating body 17 can be freely rotated, the composite rotating body 17 is slightly rotated in the direction opposite to the tightening direction as described above to relieve excessive tension of the band portion 1. The band portion can be cut in a state where the locking portion 104K of the band portion 1 and the second engagement piece 111 of the head portion 2 are properly engaged while maintaining the set binding pressure. As a result, the band portion 1 can be cut without inconvenience at a position close to the head portion 2 while realizing a stable binding state with a set binding pressure in which the band portion 1 and the head portion 2 are firmly engaged properly. Can do it.

  By the way, the band portion 1 guided from the reel support portion 13 through the base end portion 18A of the operation lever 18 to the inside of the tool body 6 passes through the groove portion 45a of the slider 45 covered with the sliding plate 44, and The guide member 52 is disposed inside the fulcrum Y portion of the swing arm 19 so as to straddle the lower portion of the tension gear 21. A path is formed so as to be passed through the guide passage 20 after being engaged with the lower portion of the tension gear 21. The slider 45 is formed with a protruding protruding tongue 45z for guiding the band part 1 coming out of the groove part 45a to the groove part 52a of the guide member 52. Further, the groove portion 52a formed in the upwardly bifurcated upper portion of the guide member 52 has a role of introducing the band portion 1 so that the engaging portion 104K is wound around the gear portion 21a of the tension gear 21. is doing.

  As shown in FIGS. 8 to 10, the linkage mechanism f depends on the positional relationship where the pin roller 18 b starts to contact the base end portion 16 b of the L-shaped arm 16, that is, the positional relationship between the operating lever 18 and the L-shaped arm 16. It is configured. Specifically, it is configured by setting the shapes and dimensions of the operation lever 18 and the L-shaped arm 16 so that the cutter blade 15 starts to move when the operation lever 18 is swung upward beyond the tightening position H. Yes.

  As shown in FIGS. 12 to 14 and FIGS. 25 and 26, the binding tool jig J is suspended in the air with respect to the upper surface (an example of a support surface) 10 a of the support substrate (an example of a support member) 10. A binding and tightening tool A for wrapping and binding the binding band V around the wire harness W routed to the wire harness W is positioned with respect to the planned binding location n in the wire harness W. A mounting portion 61 for fixing, and a positioning portion 62 for determining the position of the projecting piece 8 with respect to the mounting portion 61 in a pair with the projecting piece (an example of a specific portion) 8 provided in the binding tightening tool A; The position adjusting mechanism 63 is configured to adjust and set the distance between the positioning portion 62 and the mounting portion 61 so that the height (distance) of the positioning portion 62 from the support surface 10a can be varied.

  The mounting portion 61 includes a rod-shaped portion 61a that is press-fitted into the support substrate 10, a cylindrical portion 61b made of a pipe material, and a circular seat 61c that connects both of them and extends along the upper surface 10a. A screw hole 61d is formed at one end for screwing a shaft bolt 70 for fixing relative to the position adjusting mechanism 63 at the upper end portion of the cylindrical portion 61b, and a two-sided width portion 61e is formed at the lower end portion. Is formed. It is possible to adjust the orientation of the mounting portion 61 with respect to the support substrate 10 by fitting a tool such as a spanner or a wrench to the two-sided width portion 61e and performing a rotation operation.

  The positioning portion 62 has an upwardly bifurcated positioning main body 64, an upper wall (an example of a movable wall) 65 pivotally supported at a fulcrum p7 between the left and right side walls 64L and 64R, and an urging force for closing the upper wall 65. And a coil spring 66 or the like. The positioning body 64 has left and right side walls 64L and 64R, a lower wall 64A integrating them, a horizontal hole 64a for accommodating a spring formed in the lower wall 64A, and a shaft pin 67 that pivotally supports the upper wall 65 at a fulcrum p7. A recess 64c formed in each of the side walls 64L and 64R so as to receive both ends of the mounting holes 64b formed in the side walls 64L and 64R and the stopper pins 65a mounted on the upper wall 65. Is formed. The upper wall 65 is closed by a spring receiving piece 65b formed at the lower end of the upper wall 65 by a coil spring 66. Normally, the stopper pin 65a is fitted into the left and right recessed portions 64c and stopped (the position indicated by the solid line in FIG. 25). ).

  The position adjusting mechanism 63 is mounted in the height direction on the positioning portion 62, specifically, a steel plate mounting seat 63A which is a tip portion for fixing the positioning main body 64 with bolts, and the mounting portion 61, specifically, the cylindrical portion 61b. And a leg portion 63B made of a pipe material whose position is adjustable. The leg portion 63B is formed with a large number of insertion holes 63b through which the shaft bolt 70 is passed, and the height of the positioning portion 62 can be adjusted and set by selecting and setting the insertion hole 63b through which the shaft bolt 70 is passed. It is comprised so that. The rectangular mounting seat 63A is formed with a bolt hole 63a for passing two bolts 68 for fixing the positioning body 64 to be placed on the mounting seat 63A. In addition, as a relative fixing means of the cylindrical part 61b and the leg part 63B, the structure which uses instead of the axial bolt 70 the pin member (roll pin, headed pin, etc.) inserted / extracted over both may be sufficient.

  This binding tool jig J inserts the protrusion 8 of the binding tightening tool A into a recessed recess 69 formed by the positioning main body 64 and the upper wall 65, thereby binding the binding tightening tool A to the planned binding tool A. It is configured to be positioned at the location n. The bottom wall of the upper wall 65 is formed by a ceiling surface 65c that is horizontal in the closed position and an inclined surface 65d that widens the opening area and facilitates the insertion of the protruding piece 8. That is, a positioning operation is performed in which the tip end portion of the projecting piece 8 is inserted and matched with a portion surrounded by the left and right side walls 64L and 64R, the lower wall 64A, and the ceiling surface 65c in the recessed portion 69, and the inclined surface 65d. Functions as a guide wall for guiding the insertion movement of the protruding piece 8.

  In order to separate the binding and tightening tool A from the binding tool jig J after the binding operation is completed, the binding and tightening tool A may be pulled out in the direction opposite to the insertion direction. However, as shown in FIG. It is also possible to remove the jig from the jig J. That is, if the bundling and tightening tool A is moved vertically upward while the protruding piece 8 is inserted into the recessed portion 69, the protruding piece 8 swings the upper wall 65 against the urging force of the coil spring 66 with the fulcrum p7 as a fulcrum. This is because the upper wall 65 can be retracted and moved upward. In this way, the protruding piece 8 can be moved away from the bundling tool jig J by pulling out or ascending, so that the bundling tightening tool A can be set to the bundling tool jig J as compared with the case where only the pulling movement is possible. In addition to this, there is an advantage that the set releasing operation is easy to perform.

  In other words, the positioning portion 62 has a recessed portion 69 that can receive the protruding piece 8 protruding from the binding and tightening tool A, and left and right side walls (an example of a side wall in the front-rear direction) that form the recessed portion 69. The upper wall (an example of the left or right side wall) 65 of the upper and lower walls (an example of a side wall in the left-right direction different from the insertion / extraction direction of the protruding piece 8 into the recess 69) forms the recess 69. The upper wall 65 can be opened and closed against the elastic return force caused by the coil spring 66 when the force in the opening direction applied to the upper wall 65 exceeds a predetermined value. It is configured to state.

  Regarding the three-dimensional direction relationship between the wire harness W and the binding tool jig J (positioning portion 62), as shown in FIGS. It corresponds to the front-rear direction along the longitudinal direction of the electric wire r when the wire harness W is used as a reference, and the “Ue” direction that is the vertical direction of the positioning portion 62 is the left-right direction when the wire harness W is used as a reference. Equivalent to. The “Oka” direction which is the vertical direction in the positioning portion 62 corresponds to the insertion / extraction direction (vertical direction) when the wire harness W is used as a reference.

  In the binding of the wire harness W, the dimensional accuracy of the expected binding position n in the longitudinal direction of the electric wire r, that is, the “a” direction, is strictly required. Therefore, in the binding tool jig J shown in FIG. The left and right side walls 64L and 64R are fixed walls, and the upper wall 65 of the upper wall 65 and the lower wall 64A can be opened and closed. For example, in the configuration in which the lower wall 64A is a movable wall that can be opened and closed, or as shown in FIG. 22, the protrusion 8 is inserted and removed in the vertical direction, the front wall and the rear wall ["Oka" direction in FIG. Any of (the wall in the insertion / extraction direction)] can be a movable wall that can be opened and closed.

  The binding tool jig J has a first structure (see FIG. 27) and a second structure (see FIG. 28). As shown in FIG. 27, the binding tool jig J of the first different structure has the mounting direction of the positioning body 64 with respect to the mounting seat 63A opposite to that of the basic binding tool jig J shown in FIG. In addition, the basic binding tool jig J shown in FIG. 25 and the like is the same as that of the basic binding tool J except that the lengths of the cylindrical portion 61b and the leg portion 63B are shortened. The binding tool jig J having the first different structure is used in a third different usage of the binding and tightening tool A shown in FIG.

  As shown in FIG. 28, the binding tool jig J of the second different structure has a shape in which the mounting seat 63A is bent in an L shape so that the positioning main body 64 is placed in the horizontal position, and the cylindrical portion 61b. The basic bundling tool jig J shown in FIG. 25 and the like is the same except that the length of the leg 63B is shortened. The binding tool jig J having the second different structure is used in a first alternative usage of the binding and tightening tool A shown in FIG. 22 and a second alternative usage of the binding and tightening tool A shown in FIG.

  As described above, the binding tool jig J is different in length, but any of the basic one shown in FIG. 26, the first different structure shown in FIG. 27, and the second different structure shown in FIG. Also, the cylindrical portions 61b and the leg portions 63B have the same thickness and can be interchanged. Accordingly, the attachment portion 61 includes the first position adjustment mechanism 631 having the first tip portion t1 for setting the positioning portion 62 (that is, the recessed portion 69) in a posture facing the attachment portion 61 in the lateral direction (specific direction). The positioning portion 62 can be freely replaced with a second position adjustment mechanism 632 having a second tip portion t2 for setting the positioning portion 62 in a posture facing an upward direction with respect to the attachment portion 61 (a predetermined direction different from the specific direction). Has been. In other words, the leg part 63B shown in FIG. 28 can be inserted into the cylindrical part 61b shown in FIG. 25, or the leg part 63B shown in FIG. 25 can be inserted into the cylindrical part 61b shown in FIG. It is configured as follows.

  A bundling work procedure using the bundling and tightening tool A and the bundling tool jig J configured as described above will be described. First, as shown in FIGS. 1 and 9, in the state where the column portion 107 side portion of the head 2 is inserted and held in the recessed hole portion 56 of the tip holding portion 5, the knob 39 is grasped and slid forward. The band portion 1 having a set length is extruded from the head portion 2 (see FIG. 6). At this time, the knob 39 is immediately returned to the return position m from the pushing position k. Then, as shown in FIG. 12, the tip holding portion 5 is brought close to the harness portion n to be bound, and the protruding band portion 1 is wound around the binding scheduled harness portion n, and then the band tip The part 1t is reinserted into the band insertion hole 105 of the head part 2.

  Then, as shown in FIG. 13, the protruding piece 8 at the tip of the tool body 6 is inserted into the recessed portion 69 of the binding tool jig J and positioned, and then the operating lever 18 at the standby position T is tightened by grasping together. The operation of swinging up to the position H and pulling and tightening the band portion 1 existing inside the tool body 6 is repeated once or a plurality of times to tighten the planned binding portion n so as to be a predetermined binding pressure. When the protrusion 8 is inserted into the recessed portion 69, it may be applied to the setting portion 9 that is the innermost end or not. That is, a binding tool jig J disposed on the support substrate 10 corresponding to the binding location n is prepared, and prior to the binding process in which the binding tightening tool A is operated, A positioning step of moving the binding and tightening tool A relative to the binding tool jig J is performed so that the protruding piece 8 of the binding and tightening tool A is set in the positioning portion 62 to be equipped.

  When the bundling pressure reaches the set value by the upward swing operation of the operation lever 18, further upward swing is possible from the tightening position H of the operation lever 18 as described above, and the band portion 1 is thereby cut. When the band portion 1 is cut, as shown in FIG. 14, the upper wall 65, which is the swinging stopper 60 of the binding tool jig J, is pushed by lifting the entire binding and tightening tool A, so that the swinging movement is retracted. Then, the binding and tightening tool A can be extracted from the binding tool jig J and moved without detouring. In this way, the work using one cycle of the binding and tightening tool is completed.

  When this clamped head portion 2 is used, that is, when the binding band V with clamp is used, the clamp portion 4 protrudes from the wire harness W in the bound state as shown in FIG. When the binding and tightening tool A is separated and moved after the work, it is first necessary to move the binding and tightening tool A in the protruding direction of the clamp portion 4 (upward in FIG. 14). Therefore, the binding tool jig J can be freely opened and closed to match the projecting direction of the clamp portion 4 after binding and the recessed portion 69 where the protruding piece 8 is inserted and removed by movement in the front-rear direction with respect to the binding tightening tool A. Since the upper wall 65 is provided, the binding band V with a clamp can be equipped with excellent positioning accuracy in the longitudinal direction of the wire harness W, but does not interfere with the clamp part 4 and therefore the positional deviation of the clamp part 4 is prevented. An excellent effect is obtained that the binding and tightening tool A can be separated and moved so as not to invite.

  The tool body 6 has the following advantages due to the shape in which the tip end portion 6b is bent downward with respect to the body main body 6A. FIGS. 1 and 2 illustrate a case where the wire harness W, which is disposed on the side of the support substrate 10 mounted on the work table 91, is bundled via a harness stand 11 at a number of locations. Specifically, this is a case where the harness part w2 arranged in the front and rear middle is bound by the binding band V. The binding and tightening tool A is supported by gripping its grip portion 6a with fingers, the distal end portion 6b is bent downward, the distal end holding portion 5 is separated downward with respect to the grip portion 6a, and the head portion 2 is removed. Since the direction of the recessed hole portion 56 for insertion and holding is set to face downward by 90 degrees with respect to the grip portion 6a, the body body 6A is separated upward without interfering with the harness portion on the front side. Thus, the binding and tightening operation can be performed in a posture in which the tool body 6 is substantially horizontal as a whole, in other words, in an easy posture that does not overwhelm the wrist or arm.

  In addition, the banding operation for tightening and cutting the band portion 1 in the binding and tightening tool A is performed by the operation lever 18 that is gripped by the fingers that hold the grip portion 6 a to support the tool body 6, so that only one arm is necessary. In addition, the operation lever 18 can be operated while holding the grip portion 6a for gripping the operation lever 18 once or a plurality of times, so it is troublesome or troublesome to use both hands or to change the grip position of fingers. There is an advantage that the operation is not required, and the operation is simple and convenient.

  In addition, the usage of the binding and tightening tool A can be as follows. As shown in FIG. 22, the tool body 6 is held in a vertical posture in which the body main body 6 </ b> A is directed vertically with the body distal end portion 6 b facing down, and the distal end holding portion 5 faces the front side (operator side). This is a way of bundling work (first usage). As shown in FIG. 22, this first alternative usage method is used when binding with the clamp portion 4 facing sideways beyond the planned binding location n, or near and above the planned binding location n. This is effective in a situation where there are separate harness portions at two locations and the binding work can only be performed from the other side. In this case, if the binding tool jig J of the second different structure shown in FIG. 28 is used, the binding tightening tool A can be separated and moved in the protruding direction of the clamp part 4 after binding.

  As shown in FIG. 23, the tool body 6 is gripped in a vertical posture in which the body main body 6A is vertically oriented with the body tip portion 6b facing down and the tip holding portion 5 faces (on the side opposite to the worker). This is a way of bundling work (second usage). As shown in FIG. 23, this second alternative method is used in the case of binding with the clamp part 4 facing sideways on the near side of the binding planned location n, or in the vicinity of the side where the planned binding location n is facing and above. This is effective in a situation where there are separate harness portions at two locations and the binding work can be performed only from the front side. Also in this case, if the binding tool jig J having the second different structure shown in FIG. 28 is used, the binding and tightening tool A can be separated and moved in the projecting direction of the clamp portion 4 after binding.

  As shown in FIG. 24, the body body 6A is in the sideways orientation and the tip holding portion 5 is in the sideways orientation in which the tool body 6 is gripped in the sideways orientation (third usage method). As shown in FIG. 24, the third alternative usage method is a case of binding with the clamp portion 4 facing down on the lower side of the planned binding location n, or the side facing and the front side of the planned binding location n This is effective in a situation where there are separate harness portions in the vicinity of the upper side and the upper side, and the binding work can be performed only from the lower side. In FIG. 24, the binding tool jig J having the first different structure shown in FIG. 27 is used, and after binding, the binding tightening tool A is moved up to temporarily lift the wire harness W, and then the binding tool jig is lifted. Pull away from tool J and move. Although not shown in the figure, if a binding tool jig having a structure in which the positioning portion is suspended by using a mounting portion bent in a substantially J shape, the protruding portion 8 is moved from the positioning portion by the downward movement. External movement is possible, and the binding and tightening tool A can be pulled and moved without lifting the wire harness W once.

  That is, the displacement amount (reference symbol D in FIG. 24) relative to the body main body 6A due to the bending of the body front end portion 6b having the front end holding portion 5 is set to a relatively small eye dimension. Since the direction dimension is small, the binding tightening tool A is positioned from any of the front, rear, upper and lower directions (four directions) in the binding of the wire harness W arranged on the support substrate 10 as described above. Tightening and bundling work can be performed, and it is easy to use and improves versatility, and is versatile. In addition, the binding and tightening tool is not limited to the above-described four directions of use, and can be used in an obliquely upward or obliquely downward posture, and cannot be used in any angle of 360 degrees. It has the advantage that it can be used without any problems.

[Another Example]
The binding tool jig J may have, for example, an upward U-shaped positioning portion that receives the tip portion 6b of the tool body 6, and in this case, the tip portion 6b is the "specific portion 8". It corresponds to. Further, the positioning unit 62 having the recessed portion 69 having the movable wall 65 may be provided on the binding tool A, and the protruding piece 8 may be provided on the binding tool jig J. In this case, the positioning portion 62 having a complicated structure as compared with the projecting piece 8 may be provided only in the bundling tool, and there is an advantage that it is economically advantageous as compared with the means provided in a large number of bundling tool jigs J. . As described above, the bundling tool jig J and the specifying unit 8 are not limited to the above-described configuration, and various modified structures are possible.
