Description

The present invention relates to a binding machine used to bind an object such as a reinforcing bar. More specifically, it relates to a binding machine having a function of dealing with a defect caused by feeding or pulling back a (binding) wire.

For example, a binding machine such as a reinforcing bar binding machine is used to bind an object such as a reinforcing bar at a construction site (see, for example, Patent Document 1). This binding machine has a feeding part that sends out (pulls out and sends) a wire wound around a reel, a bending forming part that curls the wire sent from this feeding part to form a ring, and a ring made by the bending forming part. It is equipped with a twisted portion that binds by twisting and squeezing.

According to this configuration, a loop is formed by curling (or giving an arc-shaped bending habit) the wire at the bending forming portion while feeding the wire wound around the reel at the feeding portion, and twisting the loop at the twisting portion. This makes it possible to bind objects such as reinforcing bars.

Further, in the binding machine, at the time of binding, the delivered wire is pulled back and the loop is shrunk according to the size of the object, so that the amount of wire used in one binding can be reduced and the binding can be performed per reel. It is also being made possible to increase the number of times. Such wire feeding and pulling back is performed by the feeding unit.

Then, there is such a binding machine provided with an accommodating portion (reel accommodating portion) in which a reel around which a wire is wound is detachably and exchangeably attached.

Japanese Patent No. 40167884

The binding machine has the following problems.

That is, when the wire is forcibly pulled back by the feed portion, if the means for eliminating the slack of the wire is not provided, the slack of the wire occurs between the feed portion and the reel inside the accommodating portion. Become. Then, when the loosened wire bends inside the accommodating portion and the bending of the wire becomes larger than a certain curvature, the deformation withstand load of the wire decreases, so that the wire is pulled back by the force of the feed portion forcibly pulling back the wire. It breaks easily (ie, the wire buckles). In this way, if the wire breaks on the reel side of the feed section, for example, the wire cannot be fed at the next binding, or the bent or broken wire gets into the accommodating section (between the case and the cover). Then, problems such as jumping out from there will occur.

In the above-mentioned binding machine, a plurality of flexible wires having a small diameter may be used together so that the wires adhere well to an object such as a reinforcing bar. In this way, the wires having a small diameter are used. In some cases, the problem of buckling due to loose wire becomes greater.

Therefore, the main object of the present invention is to solve the above-mentioned problems.

In order to solve the above problems, in the present invention, in a binding machine provided with a feeding means for feeding a wire from a reel mounted on a housing portion, the wire pulled out from the reel by the feeding means is guided to the feeding means. A first regulating means for restricting the wire pull-out portion located between the reel and the feeding means from coming off the wire entry path is provided in the accommodating portion with respect to the wire entry path at the time. The front wall of the accommodating portion facing the wire sent out from the reel is installed at a position serving as the first regulating means, and the front wall of the accommodating portion is prevented from being worn by the contact of the wire. It is characterized in that possible wear prevention means are provided .
Further, according to the present invention, in a binding machine provided with a feeding means for feeding a wire from a reel mounted on an accommodating portion or pulling the delivered wire back to the reel side, the wire is pulled back to the reel side by the feeding means. A second regulating means for restricting the wire from coming off the wire extending in the pulling direction of the wire by the feeding means is provided in the accommodating portion, and the front wall of the accommodating portion facing the wire fed from the reel is provided . It is characterized in that it is installed at a position serving as the second regulating means, and the front wall of the accommodating portion is provided with a wear preventing means capable of preventing the front wall from being worn due to contact with a wire .

According to the present invention, according to the above configuration, the wire that is sent or pulled back from the reel by the feeding means is properly used by the first regulating means, the second regulating means, the wear preventing means of the front wall of the accommodating portion, or the like. Can be regulated.

Hereinafter, the present embodiment will be described in detail with reference to the drawings.
1 to 25 are for explaining this embodiment.

<Structure> The configuration of this embodiment will be described below.

For example, as shown in the side view of FIG. 1 and the front view of FIG. 2, a binding machine 2 such as a reinforcing bar binding machine is used to bind a (binding) object 1 such as a reinforcing bar or an electric wire at a construction site. There is. The binding machine 2 sends out the wire 3 while curling it (or giving it an arcuate bending habit) to form a ring 4 that surrounds the circumference of the object 1, and twists and squeezes the ring 4 to form a ring 4 of the object 1. It is designed to allow unity.

Hereinafter, the binding machine 2 will be described.

The binding machine 2 described above has a binding machine main body 5 and a grip 6.

In the following description, the direction is based on the state shown in FIG. 1 (the state in which the binding machine 2 is erected). Then, the longitudinal direction of the binding machine main body 5 (the direction corresponding to the left-right direction in FIG. 1) is set as the front-rear direction, and one of the directions orthogonal to the longitudinal direction of the binding machine main body 5 (in the vertical direction in FIG. 1). The corresponding direction is the vertical direction (or the height direction), and the direction orthogonal to the front-back direction and the vertical direction is the left-right direction (or the width direction). Further, one end side of the binding machine main body 5 in the longitudinal direction (the side facing the object 1, the left side of FIG. 1) is the front side or the tip side, and the other end side of the binding machine main body 5 in the longitudinal direction (opposite to the object 1). The side (right side in FIG. 1) is the rear side or the rear end side. Further, the upper side of FIG. 1 is set with reference to the binding machine main body 5, and the lower side of FIG. 1 (direction in which the grip 6 extends) is set with reference to the binding machine main body 5. Then, the back side of the paper surface (left side of FIG. 2) of FIG. 1 is the right side of the binding machine main body 5, and the front side of the paper surface of FIG. 1 (right side of FIG. 2) is the left side of the binding machine main body 5.

The grip 6 is provided so as to extend substantially downward from a substantially intermediate portion in the longitudinal direction of the binding machine main body 5. The grip 6 is provided with a trigger 7 and a lock switch 8, and a battery pack 9 can be attached to and detached from the lower portion. Then, by releasing the lock switch 8 and pulling the trigger 7 with the power switch turned on, the binding machine 2 is operated and the binding operation is performed.

An accommodating portion 11 for setting the (binding) wire 3 used for binding the object 1 such as a reinforcing bar is provided on the front side of the grip 6. In this case, the wire 3 is wound around the reel 12 in a coil shape. The reel 12 can pull out one or a plurality of wires 3 at the same time. The reel 12 around which the wire 3 is wound is set detachably with respect to the accommodating portion 11. In this case, the attachment / detachment direction of the reel 12 with respect to the accommodating portion 11 is the axial direction of the reel 12.

Further, as shown in the internal configuration diagram of FIG. 3, a feed for feeding the wire 3 wound around the reel 12 to the binding portion 15 provided on the tip side of the binding machine main body 5 is sent to the binding machine main body 5. A portion (feeding means) 16 is provided (in FIG. 3, the wire 3 is omitted). In this case, the feed portion 16 is provided at the lower end side of the binding machine main body 5. Further, the accommodating portion 11 is provided below the feeding portion 16. The accommodating portion 11 is attached in an erected state between the tip of the binding machine main body 5 and the lower end of the grip 6.

In this way, by providing the feeding portion 16 and the accommodating portion 11 at the position of the lower front side of the binding machine main body 5 (for example, as compared with the case where the accommodating portion 11 is provided on the rear end side of the binding machine main body 5). ) The weight balance of the binding machine 2 is improved to make the binding machine 2 easier to handle, and the path of the wire 3 becomes more curved, so that the ring 4 of the wire 3 can be easily formed.

As shown in the mechanical diagrams of FIGS. 4 and 5, the feed unit 16 includes at least a feed gear 17 for feeding the wire 3 and a feed motor 18 for rotationally driving the feed gear 17. A pair of feed gears 17 are provided so as to sandwich the wires 3 from the left and right, for example. One of the pair of left and right feed gears 17 is a driving wheel, and the other is a driven wheel. The feed gear 17 as a driven wheel may be a tension roller or the like that has a required pressing force on the feed gear 17 as a drive wheel and can move away from and recoil.

A V-shaped notch 19 for receiving and frictionally driving the wire 3 is provided at the center of the outer circumference of the feed gear 17 in the thickness direction, and a groove for biting extending in the circumferential direction is formed. .. An intermediate gear 21 or the like can be appropriately provided between the feed gear 17 and the output gear attached to the output shaft of the feed motor 18.

Then, by rotating the feed gear 17 in the normal direction by the feed motor 18, the wire 3 can be moved substantially upward and fed to the binding portion 15. Further, by reversing the feed gear 17 by the feed motor 18, the delivered wire 3 can be moved substantially downward and pulled back from the binding portion 15 to the accommodating portion 11. In this case, as shown in FIG. 3, the rotating shaft 22 of the feed gear 17 is tilted forward with respect to the horizontal direction so that the wire 3 is fed substantially forward and diagonally upward.

By the way, the feed amount of the wire 3 is, for example, about 250 mm, and the pullback amount of the wire 3 is, for example, about 75 mm to 115 mm (about 1/2 to 1/3 of the feed amount). However, these amounts vary depending on the diameter of the reinforcing bar as the object 1 and the number of reinforcing bars.

Further, the binding portion 15 is provided with a contact portion 25 capable of contacting the object 1. Further, the binding portion 15 is provided with a curved forming portion 26 for forming the wire 3 sent by the feeding portion 16 into a ring 4. The curved forming portion 26 has a curl arm 27 and a curl guide 28 provided in pairs (up and down) with the contact portion 25 interposed therebetween.

The curl arm 27 has a curl groove portion on the inner peripheral side thereof for curling the wire 3 (or giving the wire 3 an arcuate bending habit). The curl guide 28 has a receiving groove on the inner peripheral side thereof for receiving the wire 3 curled by the curl arm 27. Then, the wire 3 is passed between the curl arm 27 and the curl guide 28 counterclockwise in the drawing to form a ring 4. The space (gap) between the curl arm 27 and the curl guide 28 is a passing portion for passing the object 1 toward the contact portion 25.

Further, as shown in FIG. 4, the binding machine main body 5 guides or restricts the position of the wire 3 to at least the entry side and the exit side of the feeding portion 16 and at least the position of the base portion of the curl arm 27. Wire guides 31 to 33 are provided for this purpose. Of these, the wire guide 31 arranged on the inlet side of the feed portion 16 is for guiding the wire 3 from the reel 12 to the feed portion 16, and the wire guide 32 arranged on the outlet side of the feed portion 16 Is for guiding the wire 3 from the feeding portion 16 to the cutting portion 34. The cutting portion 34 is provided to separate the ring 4 portion of the wire 3 from the other portion, and has a fixed blade and a movable blade. Further, at least, the wire guide 33 arranged at the position of the base portion of the curl arm 27 can be habituated to curl the wire 3 in a loop shape.

In addition, the contact portions 25 (see FIGS. 1 and 2) on the tip end side of the binding machine main body 5 are located on both sides of the ring 4 of the wire 3 in the axial direction, and are provided in pairs on the left and right with a required interval. There is. At the position between the left and right abutting portions 25 inside the binding machine main body 5, the wire 3 formed into a ring 4 as shown in the side view of FIG. 6, the plan view of FIG. 7, and the plan sectional view of FIG. A twisted portion 35 is provided so as to tighten the wire 3 to the object 1 by twisting and squeezing the wire 3. The twisting portion 35 includes a holding portion 36 that allows the wire 3 to be sandwiched, separated, and hooked, a twisting motor 37 for rotating and twisting (twisting) the holding portion 36 by a required number of times, and a holding portion 36. It is provided with an operating mechanism 38 for opening and closing, twisting, and advancing and retreating the wire 3.

As shown in FIG. 8, the holding portion 36 includes a center hook 36a and a pair of left and right hooks 36b and 36c, and left and right wire passing portions for passing the overlapping portions of the wires 3 formed into the ring 4 separately. Can be configured. Further, the operating mechanism 38 for opening and closing the holding portion 36 mainly limits the rotation of the screw shaft 38a, the sleeve 38b screwed to the outer peripheral side of the screw shaft 38a, and the sleeve 38b, or rotates. It is composed of a screw mechanism or the like having a rotation restricting portion 38c for releasing the regulation.

The operating mechanism 38 is interposed at a position between the holding portion 36 and the twisting motor 37. The operating mechanism 38 uses the relative displacement of the sleeve 38b with respect to the screw shaft 38a in the longitudinal direction due to the rotation of the screw shaft 38a to open / close and twist the holding portion 36. Further, the operating mechanism 38 can operate the cutting portion 34, the wire guide 33 at the base of the curl arm 27, and the like in conjunction with each other by using the interlocking mechanisms 34a and 33a (see FIG. 6).

Then, when the wire 3 is twisted, the operating mechanism 38 closes the holding portion 36 (the left and right hooks 36b, 36c) to hold the overlapping portion of the wire 3 that has become the ring 4, and then twists the wire 3. Then, after the ring 4 of the wire 3 is twisted, the actuating mechanism 38 makes the holding portion 36 (the left and right hooks 36b, 36c) stand by in an open state.

The feed portion 16, the twist portion 35, and the like are controlled by a control device 39 (see FIG. 3) provided inside the binding machine main body 5.

Then, as shown in FIG. 4, the reel 12 is integrally provided with a tubular hub portion 41 that serves as a winding core of the wire 3 and a pair of axially both ends (or the periphery thereof) of the hub portion 41. It has flange portions 42 and 43. The flange portions 42 and 43 are formed to have a substantially disk shape having a diameter larger than that of the hub portion 41, and are provided concentrically with the hub portion 41. The pair of flange portions 42, 43 may have the same diameter, or the flange portions 42 located on the back side (left side in the drawing) of the housing portion 11 with reference to the attachment / detachment direction of the reel 12 with respect to the housing portion 11 are on the front side. The diameter may be smaller than that of the flange portion 43 located (on the right side of the figure). Reinforcing ribs, lightening portions, and the like can be appropriately formed on the flange portions 42 and 43 (see FIG. 6 and the like). The reel 12 is preferably formed of a resin having excellent resistance to abrasion and bending, such as ABS resin, polyethylene, polypropylene, and the like.

Further, the reel 12 is rotated (driven) as the wire 3 is pulled out without being driven to rotate inside the accommodating portion 11. Therefore, a rotation shaft portion (or rotation guide portion) for supporting the rotation of the reel 12 is provided between the reel 12 and the accommodating portion 11.

In this case, as shown in FIG. 9, the wire 3 is pulled out substantially upward by the clockwise rotation of the reel 12 from the position of the lower front portion of the reel 12. Further, the reel 12 is located on one side in the left-right direction with respect to the width center position of the binding machine main body 5 and the feeding portion 16 (for example, the left side of the binding machine main body 5 and the feeding portion 16 so that a right-handed person can easily handle it (FIG. 2. It is arranged in an offset state (on the right side of FIG. 4). In particular, the reel 12 is set to be completely offset in the left-right direction with respect to the curl arm 27.

Then, the accommodating portion 11 feeds the reel accommodating portion 11a formed as a substantially cylindrical recess capable of accommodating the reel 12 and the wire 3 drawn out from the reel 12 to the feeding portion 16 (the wire guide 31 on the entry side). A wire passage 11b configured as a passage for the wire 3 for guiding is provided. The wire passage 11b is integrally connected to the reel accommodating portion 11a to form a space (free space) through which the wire 3 can freely pass. In this case, the wire passage 11b has an upward narrowing (or downward spreading) side shape that gradually contracts from the reel accommodating portion 11a toward the feeding portion 16.

The accommodating portion 11 is composed of members such as a protective case 91 having a front wall 91a, a rear wall 91b, and a side wall 91c (see FIG. 16). The protective case 91 is made of resin and is integrated with the binding machine main body 5. Like the reel 12, the protective case 91 is preferably formed of a resin having excellent resistance to abrasion and bending, such as ABS resin, polyethylene, polypropylene, and the like.

The protective case 91 is composed of, for example, a case main body and a cover for opening and closing an opening formed on a side surface of the case main body. The case body is called a magazine or the like, and the cover is called a magazine cover. As shown in FIG. 1, a hinge portion 61 is provided between the case body and the cover, and the case body is provided with a lock device 62 for closing the opening of the case body by the cover.

Then, in this embodiment, the binding machine as described above is provided with the following configuration.

(1) As shown in FIGS. 9 (to 11), with respect to the incoming path 81 of the wire 3 when the wire 3 drawn out from the reel 12 by the feed portion 16 is guided (straightly) to the feed portion 16. A first regulating means (first regulating section) 83 for restricting the pull-out portion 3a of the wire 3 located between the reel 12 and the feeding section 16 from coming off the incoming line path 81 is provided in the accommodating section 11. ..

Here, the pull-out portion 3a of the wire 3 is a free portion from the time when the wire 3 is pulled out from the reel 12 until it is put into the feed portion 16. Explaining the incoming wire path 81, the incoming wire path 81 is directed toward the feed portion 16 when the wire 3 wound around the reel 12 has the maximum diameter (at the start of use) inside the wire passage 11b which is a free space. When the linear path (maximum path 81a) in which the wire 3 is guided straight in a taut state and the wire 3 wound around the reel 12 have the minimum diameter (or approximately the diameter of the hub portion 41), It is a range between the wire 3 and the linear path (minimum path 81b) that is guided straight toward the feed portion 16 in a taut state.

Then, the first regulating means 83 does not guide the wire 3 when the wire 3 is guided in the incoming line 81 in a taut state, and when the wire 3 loosens and comes off the incoming path 81, the wire It regulates the deviation of 3. Therefore, a required margin 84 is formed between the incoming route 81 and the first regulating means 83. The margin 84 is a small range that does not cause any trouble even if the wire 3 deviates from the incoming line 81. That is, the margin 84 is the angle formed by the first regulating means 83 and the line in the pulling direction of the wire 3 by the feed portion 16 (same as the line 86 extending in the pulling direction 85 (see FIG. 11) of the wire 3 described later). Is configured to be about 3 ° to 10 ° (preferably 5 ° or less).

When the wire 3 is wound around the reel 12 in the counterclockwise direction in the drawing, the wire 3 (the pull-out portion 3a) is loosened so as to bulge toward the front side. Therefore, the first regulating means 83 is provided at least on the front side of the incoming route 81. The specific first regulatory means 83 will be described later.

(2) A second regulating means for restricting the wire 3 pulled back to the reel 12 side by the feed portion 16 from the wire 86 extending in the pullback direction 85 (see FIG. 11) of the wire 3 by the feed portion 16. (Second regulation unit) 87 is provided in the accommodation unit 11.

Here, the pullback direction 85 of the wire 3 from the feed portion 16 (see FIG. 11) will be described. In the pullback direction 85 of the wire 3 from the feed portion 16, the pair of feed gears 17 of the feed portion 16 are opposed to each other (see FIG. 11). This is the direction in which the wire 3 goes downward when the biting portion with respect to the wire 3) is rotated so as to go downward. In the feeding direction 88 of the wire 3 from the feeding portion 16 (see FIG. 10), the pair of feed gears 17 of the feeding portion 16 are rotated so that the phase-opposing portions (engagement portions with respect to the wire 3) are directed upward. In this case, the wire 3 is in the upward direction.

The second regulating means 87 regulates the swelling due to the return of the wire 3 when the wire 3 is pulled back in a loose state. As described above, the wire 3 tends to swell toward the front side of the device. Therefore, the second regulating means 87 is provided at least on the front side of the incoming route 81. The specific second regulatory means 87 will be described later.

Further, although the first regulating means 83 and the second regulating means 87 are set separately based on different ideas, they can be made common by devising the structure.

(3) More specifically, the position where the front wall 91a of the accommodating portion 11 forming the surface facing the wire 3 sent out from the reel 12 becomes the first regulating means 83 or the second regulating means 87. It may be installed in.

In this embodiment, the front wall 91a is installed with a margin 84 on the front side of the entry path 81. At this time, by adjusting the margin margin 84 and matching the first regulating means 83 with the second regulating means 87, the front wall 91a is configured to have both functions.

(4) In the above, the front wall 91a of the accommodating portion 11 may be provided with wear preventing means 92 capable of preventing wear of the front wall 91a due to contact with the wire 3.

(5) The wear preventing means 92 may be a metal member that constitutes at least a part of the accommodating portion 11.

Here, the metal member can be a protective case 91. At least a part of the accommodating portion 11 can be the front wall 91a of the protective case 91. The wear prevention means 92 can be provided on all or at least a part of the front wall 91a.

(6) The wear preventing means 92 may be a metal member constituting the entire accommodating portion 11.

Here, the metal member can be a protective case 91. The entire accommodating portion 11 can be the entire protective case 91 (front wall 91a, rear wall 91b, and side wall 91c).

(7) Further, the wear preventing means 92 may be a metal plate attached so as to cover at least a part of the front wall 91a.

Here, the metal plate can be provided by sticking or embedding it on the inner surface of the protective case 91. In this case, the metal plate is provided over the entire inner surface of the protective case 91, or at least partially with respect to the portion of the front wall 91a.

(8) Further, the wear preventing means 92 can be a metal member provided so as to project inward of the accommodating portion 11.

(9) Alternatively, as another embodiment, as shown in FIGS. 12 (14), the first regulatory means 83 (at least a part of) may be a single or a single capable of contacting the lead-out portion 3a of the wire 3. A plurality of contact bodies 94 may be used. The contact body 94 does not need to be in constant contact with the pull-out portion 3a of the wire 3, and may be in contact with the contact body 94 at least when the pull-out portion 3a of the wire 3 is loosened.

(10) As another embodiment, as shown in FIGS. 12 (14), the second regulating means 87 (at least a part of) is pulled back located between the reel 12 and the feed portion 16. It may be a single or a plurality of contact bodies 94 capable of contacting the wire 3. The abutting body 94 does not necessarily have to come into contact with the pulled-back wire 3, and it is sufficient that the abutting body 94 can come into contact with the abutting body 94 at least when the slack of the pulled-back wire 3 becomes larger than necessary.

Here, the abutting body 94 may be a convex member provided so as to project inward with respect to the accommodating portion 11 (protective case 91), for example, a pin, particularly a metal pin. The convex member such as a metal pin has the same (contact body) as the wear prevention means 92 (relative to the front wall 91a) described above, in addition to the functions as the first regulating means 83 and the second regulating means 87. It also has an anti-wear function (as opposed to 94). The metal pin can be, for example, one with a circular cross section. Further, the metal pin may have a non-circular cross section having a convex portion protruding inward of the protective case 91, such as a semicircular or D-shaped cross section.

When the abutting body 94 is a metal pin, the metal pin extends in the axial direction of the reel 12 (the direction orthogonal to the paper surface in the drawing). The metal pin is placed (inserted or press-fitted) from the protective case 91 (in a cantilevered state) in a pin hole provided in at least one of the left and right side walls 91c (see FIG. 16) of the accommodating portion 11. Is also installed at a position inside (rear side of the front wall 91a). In this case, only one metal pin as the contact body 94 is provided at a position on the front side of the incoming line path 81.

When the contact body 94 is provided, the contact body 94 mainly functions as a regulating means (first regulating means 83 or second regulating means 87), so that the contact body 94 is in front of the accommodating portion 11. The wall 91a does not necessarily have to be the first regulatory means 83 or the second regulatory means 87. However, the contact body 94 and the front wall 91a may be combined, and both may be used as the first regulating means 83 or the second regulating means 87.

Further, the abutting body 94 may be detachably configured with respect to the accommodating portion 11 so as to be replaceable when worn. Further, in the abutting body 94, for example, a part of the wear preventing means 92 for the front wall 91a is partially projected inward of the accommodating portion 11 so as to have a convex shape similar to that of a metal pin. It may be provided.

(11) Further, as shown in FIG. 14B, the contact body 94A is a movable body (movable type) in which the contact portion with the wire 3 can move instead of the fixed type contact body such as a metal pin. It can be a contact body) or the like.

(12) The movable body can be, for example, a rollable roller. As shown in FIG. 14C, the roller is provided with a rotating shaft 94a and a tubular roller main body 94b externally fitted to the rotating shaft 94a. It is desirable that the roller body 94b is provided with its own wear prevention means 92, and for that purpose, for example, the entire roller body 94b can be made of metal. Alternatively, a metal sleeve, a metal belt (steel belt), or the like may be attached to the surface of the roller body 94b as the wear prevention means 92. The metal sleeve and the metal belt may be detachably attached to the roller body 94b. Further, by detachably attaching a locking member such as an E-ring 94c to the tip of the rotating shaft 94a, the roller body 94b itself can be held detachably and interchangeably.

In this case, only one roller (movable body) as the contact body 94A is provided at a position on the front side of the incoming line path 81. However, as shown in FIG. 14D, a plurality of abutting bodies 94 and 94A (metal pins and rollers (movable bodies) as) are provided along a position in front of the incoming line path 81 with a required interval. Books (three in the figure) may be provided. The metal pins and rollers may be mixed and used. Further, when a plurality of contact bodies 94 and 94A (metal pins and rollers (movable bodies) as) are provided, a metal belt (steel belt) or the like is further hung between them. It may be a conveyor-like movable body.

(13) The contact body 94 may be a convex member provided so as to project inward of the accommodating portion 11.

(14) In the above, the feeding direction 88 or the pulling back direction 85 of the wire 3 by the feeding portion 16 is directed in the direction of the tangent to the virtual circle 95 set at or near the maximum diameter portion of the reel 12.
Then, at least one contact body 94 is installed at or near the position of the contact point between the tangent line and the virtual circle 95.

Here, in the reel 12, the flange portions 42 and 43 are the maximum diameter portions. Therefore, the virtual circle 95 set in the maximum diameter portion of the reel 12 is the outer peripheral edge of the flange portions 42 and 43. Further, the virtual circle 95 set in the vicinity of the maximum diameter portion can be, for example, a circle along the inner peripheral wall of the reel accommodating portion 11a. The inner peripheral wall of the reel accommodating portion 11a has a diameter slightly larger than that of the flange portion 42 on the back side so that the reel 12 can be inserted.

The tangent line corresponds to the line 86 (see FIG. 11) extending in the pullback direction 85 of the wire 3. The abutting body 94 is provided at a position slightly above the tangent line on the front side of the device.

(15) Then, as shown in FIG. 15 (FIG. 16), the rear of the wire 3 entry path 81 (see FIG. 9) when the wire 3 drawn from the reel 12 in the accommodating portion 11 is guided to the feed portion 16. A third regulating means (third regulating section) 96 for regulating the wire 3 may be provided on the side (right side of FIG. 15).

Here, the third regulating means 96 regulates the deformation of the wire 3 toward the rear (deformation due to meandering, etc.). The deformation of the wire 3 toward the rear is caused by the fact that the wire 3 (the pull-out portion 3a) is first deformed so as to bulge toward the front, and then there is no escape place to the front.

(16) The third regulating means 96 can be, for example, a holding rib extending from the side wall 91c of the accommodating portion 11 (protective case 91).
Here, the pressing rib (third regulating means 96) is installed at a position behind the minimum path 81b of the wire 3 with a slight margin 64a with respect to the minimum path 81b. In this case, the holding rib is provided at a position close to the feed portion 16 above the protective case 91 so as to extend substantially in the axial direction of the reel 12 in a cantilever state.

<Action> The action of this example will be described below.

As shown in FIGS. 1 and 3, the binding machine 2 mounts the reel 12 around which the wire 3 is wound on the accommodating portion 11, and rotates the reel 12 clockwise from the position of the lower front portion of the reel 12. By pulling out the wire 3 upward and passing it through the feed portion 16 or the curl arm 27 of the curve forming portion 26, the wire 3 can be used.

Then, the power switch of the binding machine main body 5 is turned on, the lock switch 8 is released, and the object 1 such as a reinforcing bar is brought into contact with the contact portion 25 at the tip (binding portion 15) of the binding machine main body 5 to trigger. By pulling 7, the binding machine 2 is operated to bind the object 1 such as a reinforcing bar.

At this time, when the trigger 7 is pulled, first, as shown in FIG. 17, the wire 3 is fed by the feed gear 17 of the feed portion 16 toward the upper curl arm 27 by a specified amount, and the curl arm 27 (the curl groove portion) is fed. ) Causes the wire 3 to be curled at the position of the curl arm 27 and downward. The tip of the curled wire 3 turns counterclockwise and jumps into the curl guide 28, is guided by the curl guide 28, passes through the holding portion 36 of the twisted portion 35, and becomes a ring 4 surrounding the object 1. It abuts against the base of the curl arm 27 (wire feeding process).

Next, the twisting portion 35 operates, and the wire guide 33 at the base of the curl arm 27 regulates and holds the position of the tip of the wire 3 formed into the ring 4 via the interlocking mechanism 33a (see FIG. 6) or the like. The tip portion of the wire 3 is held by the portion 36 (wire gripping step).

Further, as shown in FIG. 18, the feed gear 17 of the feed unit 16 reverses and pulls the wire 3 downward by a predetermined amount (wire return step). By pulling back the wire 3, the amount of the wire 3 used for one bundling can be minimized and the number of bundling possible times can be increased. In addition, the winding shape of the wire 3 that binds the object 1 is small and neat. However, when the wire 3 is pulled back, the wire 3 may loosen inside the accommodating portion 11. In addition to the above, the slack of the wire 3 may be caused by, for example, a case where the reel 12 has rotated too much due to rotational inertia when the wire 3 is pulled out, or a vibration generated in the binding machine 2 during binding. This can also occur when the reel 12 is rotated excessively little by little.

Subsequently, as shown in FIG. 19, the cutting portion 34 operates to cut the wire 3 (wire cutting step).

After that, as shown in FIG. 20, the holding portion 36 of the twisted portion 35 twists to twist the wire 3, and the holding portion 36 advances to make the ring 4 smaller and to make the twisted portion of the wire 3 a reinforcing bar or the like. The object 1 is brought close to the object 1 and bound by tightening (wire twisting step).

Finally, as shown in FIG. 21, the holding portion 36 is retracted from the object 1 such as a reinforcing bar, and the binding is completed by releasing the twisted portion of the wire 3 (wire release step).

<Effect> According to this embodiment, the following effects can be obtained.

(Effect 1) Accommodates a first regulating means 83 for restricting the pull-out portion 3a of the wire 3 located between the reel 12 and the feed portion 16 from coming off the entry path 81 of the wire 3 led to the feed portion 16. It was provided in the part 11. As a result, the lead-out portion 3a of the wire 3 can be regulated by the first regulating means 83 so as not to be significantly deviated from the incoming line path 81. That is, due to slackening of the wire 3 when the wire 3 is pulled back, a case where the reel 12 rotates too much due to rotational inertia when the wire 3 is pulled out, or a vibration generated in the binding machine 2 during binding. It is possible to regulate the slack of the wire 3 that occurs when the reel 12 is rotated excessively little by little.

Further, as described above, the pull-out portion 3a of the wire 3 is restricted so as not to be significantly deviated from the incoming line path 81, so that the pull-out portion 3a of the wire 3 is bent in a state where the deformation load resistance is high (that is, the pull-out portion 3a is bent). It becomes possible to maintain a state close to a straight line without any problem), and the large bending of the drawer portion 3a prevents the deformation load resistance of the drawer portion 3a from decreasing and causing a state in which buckling or the like is likely to occur. can do.

On the other hand, when the first regulating means 83 is not provided at all, as shown in FIGS. 22 (to 25), the accommodating portion 11 is set larger than necessary to maximize the slack of the wire 3. It is conceivable to make it acceptable (excess margin 84a).

However, if the accommodating portion 11 is made unnecessarily large, it may seem good at first glance. For example, while the feeding of the wire 3 shown in FIG. 23 and the pulling back of the wire 3 shown in FIG. 24 are repeated, the accommodating portion 11 is used. The loose wire 3 gradually swells inside the wire 3 and comes into contact with the front wall 91a of the wire passage 11b and sticks to the front wall 91a. Then, the wire 3 attached to the front wall 91a of the wire passage 11b becomes more bent when there is no escape to the front side due to the large bulge, and the deformation load resistance is significantly reduced. It bends to the rear side and causes deformation (meandering, etc.) of the wire 3 toward the rear as shown in FIG. Therefore, if the margin 84 is made larger than necessary, the wire 3 will be violent and the like will be promoted, which is likely to cause a problem.

On the other hand, as in this embodiment, by providing the first regulating means 83 inside the accommodating portion 11 and appropriately restricting the disconnection of the wire 3 with respect to the incoming line path 81, the above-mentioned wire in the accommodating portion 11 It is possible to effectively prevent deformation such as buckling and meandering of 3.

(Effect 2) Further, when the wire 3 fed by the feed portion 16 (reversal) is forcibly pulled back, if the wire 3 is separated from the wire 86 extending in the pullback direction 85 of the wire 3 by the feed portion 16, the wire 3 The drawer portion 3a tends to be in a bent state. When the bending of the pull-out portion 3a of the wire 3 becomes larger than a certain curvature, the deformation withstand load of the wire 3 decreases (compared to the case where the wire 3 is in a straight state) as described above, so that the feed portion 16 The pull-out portion 3a of the wire 3 is easily broken by the force for forcibly pulling back the wire 3 (that is, the pull-out portion 3a of the wire 3 is likely to buckle).

If the pull-out portion 3a of the wire 3 is broken in this way, for example, the wire 3 cannot be fed at the next binding, or the wire 3 pops out from the accommodating portion 11.

Therefore, the wire 3 (pulled out portion 3a) pulled back to the reel 12 side by the feed portion 16 is regulated so as not to deviate from the wire 86 extending in the pulling direction 85 (see FIG. 11) of the wire 3 by the feed portion 16. The regulating means 87 of 2 is provided in the accommodating portion 11.

As a result, the pull-out portion 3a of the wire 3 is less likely to be bent. Therefore, the deformation withstand load of the pull-out portion 3a of the wire 3 does not decrease, and the feed portion 16 forcibly pulls back the wire 3 to pull out the wire 3. It is possible to prevent the 3a from being easily broken. Therefore, for example, it is possible to effectively prevent problems such as the wire 3 being unable to be fed at the next binding and the wire 3 popping out of the accommodating portion 11.

Moreover, in order to facilitate the formation of the ring 4 by the bending forming portion 26, the feeding portion 16 may bend (curl) the wire 3 to some extent when the wire 3 is fed. In such a case, when the feed portion 16 is reversed and the wire 3 is pulled back, a part of the wire 3 curled by the feed portion 16 is returned to the reel 12 side with a bending habit. .. Due to such curling, the pull-out portion 3a of the wire 3 tends to be easily displaced with respect to the wire 86 extending in the pullback direction 85 of the feed portion 16. However, such a deviation (from the line 86 extending in the pullback direction 85) of the pull-out portion 3a of the wire 3 due to pulling back the curled wire 3 can also be effectively prevented by providing the regulating means 87. it can.

In particular, when a wire 3 having a small wire diameter (for example, a wire diameter of about 0.5 mm to 1.5 mm) is used, the wire 3 itself is easily bent, so that the wire 3 is pulled back from the wire 86 by the feed portion 16. The wire 3 is likely to be displaced or buckled, but even in such a case, by providing the second regulating means 87, the wire 3 is prevented from being displaced or the wire 3 is buckled. It is possible to stably continue the wire connection work in which the wire is repeatedly sent and pulled back.

(Effect 3) Even if the front wall 91a of the accommodating portion 11 forming a surface facing the wire 3 sent out from the reel 12 is installed at a position serving as the first regulating means 83 or the second regulating means 87. good. As a result, the front wall 91a of the protective case 91 can be effectively used to provide the regulating means 83, 87, and it is possible to eliminate the need to provide the dedicated regulating means 83, 87 separately from the protective case 91. .. Further, by using the protective case 91 as the regulating means 83 and 87, it is possible to reduce the size of the binding machine 2 and the accommodating portion 11.

(Effect 4) The front wall 91a of the accommodating portion 11 is provided with wear preventing means 92 capable of preventing wear of the front wall 91a due to contact with the wire 3. As a result, even if the wire 3 (the lead-out portion 3a) is loosened and detached from the incoming line path 81 and comes into contact with the front wall 91a of the protective case 91 which is the regulating means 83, 87, the wire 3 is in contact with the contacted wire 3. Wear of the protective case 91 due to rubbing can be prevented by the metal wear preventing means 92. Further, since the metal wear preventing means 92 reduces the frictional resistance between the wire 3 and the wire 3, the wire 3 that comes into contact with the protective case 91 that is separated from the incoming wire path 81 sticks to the protective case 91 and does not move. Can be prevented. Therefore, by providing the metal wear preventing means 92, even if the wire 3 comes into contact with the protective case 91 or sticks to the protective case 91, the wire 3 is prevented from buckling and the like. You will be able to pull out and pull back smoothly.

(Effect 5) The wear preventing means 92 can be a metal member that constitutes at least a part of the accommodating portion 11. For example, the wear prevention means 92 can be provided on at least a part or all of the front wall 91a of the protective case 91 constituting the accommodating portion 11. As a result, it is possible to prevent at least a part or all of the protective case 91 from being worn.

(Effect 6) Specifically, the wear preventing means 92 can be a metal member (for example, a protective case 91) that constitutes the entire accommodating portion 11. As a result, the entire protective case 91 can be used as the wear prevention means 92.

(Effect 7) Further, the wear preventing means 92 can be a metal plate attached so as to cover at least a part of the front wall 91a. As a result, the metal plate can effectively prevent the accommodating portion 11 from being worn. In this case, the metal plate can be provided by sticking or embedding the entire inner surface of the protective case 91 or at least the portion of the front wall 91a.

(Effect 8) Further, the wear preventing means 92 can be a metal member provided so as to project inward of the accommodating portion 11. As a result, it is possible to effectively prevent the accommodating portion 11 from being worn by the metal member.

(Effect 9) The first regulating means 83 (at least a part of) may be a single or a plurality of contact bodies 94 capable of contacting the pull-out portion 3a of the wire 3. The slack of the wire 3 when the wire 3 is pulled out can be effectively regulated by the single or a plurality of abutting bodies 94.

(Effect 10) The second regulating means 87 (at least a part of) may be a single or a plurality of contact bodies 94 capable of contacting the pulled-back wire 3 located between the reel 12 and the feed portion 16. good. The slack of the wire 3 when the wire 3 is pulled back can be effectively regulated by the single or a plurality of abutting bodies 94.

(Effect 11) The contact body 94A may be a movable body (movable contact body) in which the contact portion with the wire 3 can move. By making the contact body 94A a movable body in this way, it is possible to make the contact body 94 more resistant to wear (compared to the case where the contact body 94 is a fixed contact body such as a pin). As a result, even when the binding machine 2 is used in an adverse environment where dust or the like is likely to be generated, the abutting body 94A is less likely to be worn, so that the performance against feeding and pulling back of the wire 3 is achieved. Can be maintained for a long period of time.

(Effect 12) Specifically, the movable body may be a roller. In this way, by using the contact body 94A (movable body) as a roller, it is possible to actually make it resistant to wear. Then, by making the roller body 94b itself made of metal or having a metal surface such as a metal sleeve or a belt, the contact body 94A can be made more resistant to wear. Further, by making the roller body 94b removable and replaceable, even if a movable body such as a roller is worn, the function can be recovered by replacement, so that the function of the contact body 94A can be maintained for a long period of time.

(Effect 13) Further, the abutting body 94 may be a convex member provided so as to project inward of the accommodating portion 11. By making the abutting body 94 a convex member in this way, the above-mentioned action and effect can be obtained.

(Effect 14) The feeding direction 88 or pulling back direction 85 of the wire 3 by the feeding portion 16 is tangential to the virtual circle 95 set at or near the maximum diameter portion of the reel 12 in a state where the wire 3 is loosened. I tried to point it. As a result, the feeding direction 88 and the pulling back direction 85 of the wire 3 by the feeding portion 16 can be brought closer to the direction of the wire 3 entry path 81 from the reel 12 to the feeding portion 16 within a reasonable range. As a result, it becomes easy to install the contact body 94 at a position effective for both the regulating means 83 and 87.

Further, at least one contact body 94 is installed at or near the position of the contact point between the tangent line and the virtual circle 95 described above.

When the wire 3 is pulled back by the feed portion 16, the pulled-back wire 3 (pull-out portion 3a) unwinds the wire 3 with respect to the reel 12 inside the reel accommodating portion 11a (see the portion 131 in FIG. 1). After swelling as described above, there is a tendency for the swelling to be transmitted from the side close to the reel 12 toward the feed portion 16 inside the wire passage 11b.

Therefore, by installing the abutting body 94 at or near the contact point between the feeding direction 88 of the feeding portion 16 and the virtual circle 95 in a state where the wire 3 is loosened, the contact body 94 can be installed inside the wire passage 11b. It is effective because the slack of the wire 3 can be regulated at an early stage. Moreover, the number of contact bodies 94 to be installed can be reduced.

Further, by installing the contact body 94 at or near the position of the contact point between the feeding direction 88 of the feeding portion 16 and the virtual circle 95, the wire 3 pulled back to the reel 12 side by the feeding portion 16 moves forward. The wire 3 can be separated from the front wall 91a of the protective case 91 so that the wire 3 does not come into close contact with the front wall 91a of the protective case 91 when slackened so as to swell.

(Effect 15) When the feed portion 16 is reversed to pull back the wire 3, the wire 3 (pulled out portion 3a) pulled back to the reel 12 side greatly swells toward the front side of the incoming line path 81 as described above. When there is no room for swelling in contact with the front wall 91a, the wire 3 bends in a meandering manner toward the rear side of the entry path 81, and finally the wire 3 buckles and the accommodation portion 11 Problems such as popping out will occur.

Therefore, a third regulating means 96 is provided at a position on the rear side of the entry path 81 of the wire 3 when the wire 3 is guided to the feed portion 16. As a result, the wire 3 can be regulated on the rear side of the incoming line path 81, and the rearward deformation of the wire 3 can be directly suppressed by the third regulating means 96. Therefore, it is possible to reliably prevent the wire 3 from bending backward, buckling of the wire 3 due to this bending, popping out from the accommodating portion 11, and the like by the third regulating means 96.

(Effect 16) The third regulating means 96 is a holding rib extending from the side wall 91c of the accommodating portion 11 (protective case 91). As a result, the accommodating portion 11 is provided with the third regulating means 96, and the above-mentioned action and effect can be surely obtained by the third regulating means 96.
