Description

  The present invention relates to a horticultural binding machine, and more particularly to a horticultural binding machine that positions an object to be bound and binds a binding tape around the object to be bound without slack.

  A horticultural binding machine is a hand-held tool having a mechanism similar to a manual stapler, and is a tool for binding vines and branches of vineyard crops such as cocoons and peppers to a column or the like (see, for example, Patent Document 1).

  In such a binding machine, the binding operation is performed by opening and closing the clincher arm with respect to the binding machine body including the tape reel and the staple magazine. When the clincher arm is closed once, the stopper mechanism of the picking plate is released, and the picking plate pierces the binding tape drawn from the tape reel to the tip of the binding machine body. When the binding machine body and the clincher arm are opened, the tape is pulled out from the binding machine body side at the same time, and the binding tape is stretched between the binding machine body and the tip of the clincher arm.

  Next, in this state, the horticultural binding machine is pushed forward, and the binding material such as the vine of the crops and the column is taken into the space between the binding machine body and the clincher arm, and the binding tape is used as the binding object. Hanging around in a U shape. Thereafter, when the clincher arm is closed, the leading end portion of the binding tape overlaps the subsequent portion to form a loop.

  Finally, by strongly closing the binding machine body and the clincher arm, staples are driven out from the staple magazine, the overlapping portions of the binding tape are stapled, and the cutter blade also protrudes to cut the binding tape. When the clincher arm is opened and the object to be bound is taken out, one cycle of the binding process is completed.

  However, when the object to be bound is taken into the space between the binding machine main body and the clincher arm and the binding tape is wrapped around, if the object to be bound is pushed too far into the space, the binding tape will be pulled out excessively. There has been a problem that slacking occurs between the object to be bound and the binding tape.

Therefore, by pulling back the excessively drawn tape and removing the slack of the tape before bundling, a mechanism that eliminates the gap between the bundling object and the tape and makes it difficult to displace the bundling objects after bundling. A bundling machine having the above has been developed (see Patent Document 2).

  However, it is difficult to reliably loosen the object to be bound with the conventional slack-return mechanism, and even if the binding tape is pulled back, there is a possibility that an extra space will be created between the object to be bound and the binding tape and the slack will not be resolved. There is.

  The present invention solves the above-described problems, and after the binding tape is wound around the object to be bound taken in the space between the binding machine main body and the clincher arm, the binding tape is pulled back, and the binding tape is securely loosened. It is an object of the present invention to provide a horticultural binding machine that can be used.

  In order to solve the above-mentioned problem, the invention according to claim 1 is directed to pulling out a binding tape wound around a tape reel stored in a tape reel storage portion of a binding machine body, and to the binding machine body and the binding machine body. It is stretched between the ends of the clincher arm that has been opened and opened, and the object to be bound is taken into a space for taking in the object to be bound formed between the binding machine body and the clincher arm, and the binding tape is attached to the object to be bound. For horticultural use, after the clincher arm is closed and hung around the bundle, the slack of the bundling tape is pulled back by a pull-back mechanism, the overlapping portion of the bundling tape is stapled, and the bundling tape is cut with a cutter blade In the binding machine, the pull-back mechanism binds to a support shaft provided in the binding machine body in response to a closing operation of the clincher arm. A tension arm capable of retracting the loop and a block lever for restricting the rotation of the tension arm are rotatably provided, and the binding tape is suspended from each end of the tension arm and the block lever, and the tension arm Is formed with an engaging portion that can be engaged with an engaging shaft at an end of the operating arm connected to the clincher arm, and the engaging shaft of the operating arm is connected to the engaging portion on the block lever. A block portion for preventing engagement is formed, and the block lever is rotated by the tension of the binding tape pulled out when the binding tape is wound around the object to be bound, so that the block portion is engaged. When the engagement shaft of the tension arm is engaged with the engagement portion by retreating out of the portion, the operating arm is operated when the clincher arm is closed. Accordingly, characterized in that the pull back the binding tape by rotating the tension arm.

  According to a second aspect of the present invention, in the first aspect, a guide groove that slidably guides the engaging shaft at the end of the operating arm is formed in an intermediate portion of the tension arm, and is formed at one end of the guide groove. Is formed by bending the engaging portion, and when the block portion of the block lever is at the engaging portion position of the guide groove, the engaging shaft is engaged with the engaging shaft of the operating arm. It is characterized in that it is prevented from engaging.

  According to a third aspect of the present invention, in the first or second aspect, the binding machine body prevents the binding tape from being pulled out from the tape reel in conjunction with the rotation of the tension arm in the pull-back direction. A tape pull-out preventing means is provided.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, in the binding machine body, the block lever is prevented from engaging the engagement shaft of the tension arm with the engagement portion. And a second elastic member for urging the tension arm so as to rotate in a direction in which the engagement shaft engages with the engagement portion. Provided, and the biasing force of the second elastic member is smaller than that of the first elastic member.

  According to a fifth aspect of the present invention, in the first aspect of the present invention, the guide member that protrudes into the bound object taking-in space when the bound tape is wound around the bound object is engaged with the bound object. A guide mechanism for positioning the object to be bound is provided.

  According to a sixth aspect of the present invention, in the fifth aspect, the guide mechanism is provided such that an intermediate portion of the guide member is rotatably provided on a rotation shaft of the binding machine body, and one end portion of the guide member is provided in the space portion. And the other end portion of the guide member is engaged with the clincher arm, and the one end portion of the guide member is moved to the space in conjunction with the closing or opening operation of the clincher arm. It is characterized by projecting or retracting the part.

  According to the first aspect of the present invention, the bundling tape pull-back mechanism includes a tension arm capable of pulling back the bundling tape in response to a closing operation of the clincher arm on a support shaft provided in the bundling machine body, and the tension arm A block lever for restricting the rotation is rotatably provided, and the binding tape is suspended from each end of the tension arm and the block lever, and the end of the operating arm connected to the clincher arm is attached to the tension arm. An engagement portion that can be engaged with the engagement shaft is formed, and a block portion that prevents the engagement shaft of the operating arm from engaging with the engagement portion is formed on the block lever, and the bundling is performed. The block lever is revolved out of the engagement portion by rotating the block lever by the tension of the binding tape pulled out when the tape is wound around the object to be bound. Thus, when the engagement shaft of the tension arm is engaged with the engagement portion and the clincher arm is closed, the tension arm is rotated by the operation arm to pull back the binding tape. Thus, by this pulling back, the binding tape hung around the object to be bound is loosened and tensioned. Therefore, even when the binding tape is pulled out excessively, the binding tape can be brought into close contact with the object to be bound and bound without slack. For this reason, it is possible to reliably hold the bundled binding tape to the binding location, and the binding tape that is bound after binding is not displaced, and it is possible to make it difficult to displace the objects to be bound after binding. It becomes. Further, when the binding tape is used for binding, the binding tape does not sag, so that the amount of the binding tape used can be minimized.

  According to the second aspect of the present invention, a guide groove for slidably guiding the engagement shaft at the end of the operating arm is formed in the intermediate portion of the tension arm, and the engagement groove is formed at one end of the guide groove. And when the block portion of the block lever is at the engaging portion position of the guide groove, the engaging shaft engages with the engaging shaft of the operating arm and the engaging shaft engages with the engaging portion. Therefore, in the normal closing operation of the clincher arm, the engagement shaft of the operating arm slides along the guide groove, so that the tension arm does not rotate. On the other hand, before the clincher arm is closed, the block lever is rotated so that the block portion retreats out of the engagement portion, whereby the engagement shaft of the operation arm is moved to the engagement portion. When engaged, the binding tape suspended from the tip of the tension arm can be pulled back by rotating the tension arm by the operating arm when the clincher arm is closed.

  According to a third aspect of the present invention, the binding machine body has tape pull-out preventing means for preventing the binding tape from being pulled out from the tape reel in conjunction with rotation of the tension arm in the pull-back direction. Since it is provided, when the tension arm is rotated, the bundling tape is pulled back only by the amount of the bundling tape that has been wound around the bundling object, so that the bundling tape can be surely loosened.

  According to a fourth aspect of the present invention, in the binding machine body, the block lever is urged so as to rotate in a direction that prevents the engagement shaft of the tension arm from entering the engagement portion. A first elastic member, and a second elastic member that urges the tension arm to rotate in a direction in which the engagement shaft engages the engagement portion. Since the biasing force of the second elastic member is made smaller, the engagement shaft of the operating arm is moved to the engagement portion by the second elastic member only when the block lever is rotated by the first elastic member. Can be engaged. Therefore, the engagement shaft of the operating arm is engaged with the engagement portion only when the block lever is rotated by the tension of the binding tape pulled out when the binding tape is wrapped around the object to be bound. be able to.

  According to the invention which concerns on Claim 5, when a binding tape is hung around a binding object in a binding machine main body, the guide which protrudes into the space for taking in the binding object between a binding machine main body and a clincher arm is carried out. Since the guide mechanism for positioning the object to be bound by engaging the member with the object to be bound is provided, the object to be bound can be positioned and held at a position where it can be surely slackened back. Therefore, even when the binding tape is pulled out excessively, it can be surely slackened back and tightly bonded to the object to be bound, and a good binding state can be obtained.

  According to the sixth aspect of the invention, the guide mechanism causes the one end portion of the guide member to project into or retract from the space portion in conjunction with the closing or opening operation of the clincher arm. After the bundle is taken in and the binding tape is wound around, when the clincher arm is closed, the object to be bound can be engaged with the guide portion and positioned. As a result, it is possible to easily return the slack of only the binding tape and bring the tape into close contact with the object to be bound. Further, when the object to be bound is taken into the space, the clincher arm is in the open position and the guide member is in the retracted position, so that there is no obstacle during the taking operation. Furthermore, when the clincher arm is closed and operated with one hand, the one end of the guide member automatically protrudes into the space, so that it is not necessary to move the guide member with the other hand.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a side view of a horticultural binding machine showing an embodiment of the present invention.

  This binding machine is a combination of an elongated binding machine main body 1, a clincher arm 2 and a handle lever 3. A tape reel storage section 4 is attached to the rear of the binding machine main body 1, and the tape reel storage section 4 A horticultural binding tape T is pulled out from a tape reel (not shown) housed inside, and can be pulled out from a tape guide portion 5 at the tip of the binding machine body 1.

  A magazine 6 is disposed at the front of the binding machine body 1. The magazine 6 is provided with a staple launching portion 7 at the front end of the staple storage portion, and its rear end is provided at an intermediate portion of the binding machine body 1 and is rotatably attached to a support shaft 8 that supports the base portion of the clincher arm 2. It has been. The magazine 6 stores connected staples (not shown) in which gate-shaped staples are connected.

  Furthermore, as shown in FIG. 11A, a driver plate 10 for driving the leading staple of the magazine 6 from the driving unit 7 is provided at the front end of the binding machine main body 1, and the outside of the driver plate 10 (the left hand in the drawing). (Direction), a cutter blade 11 is attached, and a tape guide portion 5 is provided on the outside thereof. Furthermore, an engagement plate 12 is formed outside the tape guide portion 5. Reference numeral 9 in FIG. 1 denotes a pressing member that serves as a resistance when the binding tape moves in the return direction, and a sponge or the like may be used.

  As shown in FIG. 1, the base portion of the clincher arm 2 is pivotally supported by a support shaft 8, and is connected to an intermediate portion near the base portion so that the handle lever 3 intersects via a support shaft 14. . The handle lever 3 includes an operation portion 3a and a link portion 3b, and the link portion 3b engages with a fixed shaft 19 protruding from the side surface of the binding machine body 1. The clincher arm 2 is normally biased to be in an open state.

  As shown in FIG. 11A, a clincher groove 15, a receiving plate 16, and a picking plate 17 are arranged in this order from the inner side to the outer side (from the right hand direction to the left hand direction) in the tip head portion 2 a of the clincher arm 2. A switch plate 18 is formed on the side of the plate 17. The picking plate 17 swings and is provided so as to be inserted into a hole (not shown) in the center of the receiving plate 16.

  As shown in FIGS. 1 and 11A, the launching portion 7 of the binding machine body 1 and the clincher groove 15 of the clincher arm 2 are connected to the engagement plate 12 of the binding machine body 1 and the switch plate of the clincher arm 2. 18 are provided so as to correspond to each other.

  Next, the basic binding operation of the binding machine will be described. First, the clincher arm 2 is closed and operated by gripping the operation portion 3a of the handle lever 3 with respect to the binding machine body 1, as shown in FIG. Further, the switch plate 18 at the front end is brought into contact with the engagement plate 12 at the front end portion of the binding machine body 1 and stops. However, when a little force is applied, the switch plate 18 is moved to the engagement plate as shown in FIG. 12, the picking plate 17 is swung and the tip of the binding tape T that hangs down in front of the receiving plate 16 is inserted into the hole of the receiving plate 16 to grasp the end of the binding tape T. When the handle lever 3 is opened in this state, the clincher arm 2 is opened, and the binding tape T is pulled out from the tape guide portion 5 and opened between the binding machine body 1 and the clincher arm 2 as shown in FIG. Stretched on. As shown in FIG. 5, the space S between the binding machine main body 1 and the clincher arm 2 is obtained by taking the binding object P (for example, the vine and the support of the crop) from the outside (left hand side in the drawing) of the binding tape T. When the clincher arm 2 is closed and operated again by gripping the handle lever 3, the binding tape T is wrapped around the object to be bound P and overlaps the clincher groove 15 as shown in FIG. As shown in FIG. 11D, the switch plate 18 sunk by the closing operation is pressed by the engagement plate 12 of the binding machine body 1 and further sunk, and the picking plate 17 is linked with the binding tape T in conjunction with this. Since the magazine 6 is pushed up and rotated at the same time as being separated from the original position, the driver plate 10 and the cutter blade 11 protrude relatively so that the driver plate 10 staples. At the same time binds the overlapping portions of the binding tape T out Chi, the cutter blade 11 cuts the original side of the binding portion of the binding tape T. Further, as shown in FIG. 1, the handle lever 3 is opened and the clincher arm 2 is opened to operate to remove the object to be bound P bound by the binding tape T, thereby completing the binding operation and preparing the next binding operation. Is done.

  Next, the binding machine is provided with a pull-back mechanism A that pulls the binding tape T around the object to be bound P and then pulls the binding tape T back in the direction opposite to the pull-out direction so as to loosen the binding tape T.

  That is, the binding tape pull-back mechanism A includes, as shown in FIG. 1, a tension arm 21 rotatably provided on a support shaft 20 provided in the binding machine body 1, a block lever 22, and an operating arm 23. It is configured.

  As shown in FIGS. 1 and 7A and 7B, a base member 24 is fixed to the binding machine body 1 on the side opposite to the side where the clincher arm 2 and the handle lever 3 are arranged. The support shaft 20 is provided at 24.

  The tension arm 21 is a main member that allows the binding tape T to be pulled back in conjunction with the closing operation of the clincher arm 2, and a base portion is rotatably supported by the support shaft 20. The tension arm 21 normally has a distal end directed toward the distal end portion of the binding machine body 1, but when rotating, the tension arm 21 rotates around the support shaft 20 and rises upward in the figure.

  A roller 25 for suspending the binding tape T is fixed to the tip of the tension arm 21. The roller 25 is preferably made of a material that increases friction with the binding tape T. A fan-shaped guide groove 26 is formed in an intermediate portion of the tension arm 21. An end portion of the guide groove 26 on the tension arm 21 side is bent at a right angle to form an engaging portion 27.

  A metal tape presser 28 is attached to the base of the tension arm 21 as a tape pull-out preventing means. An intermediate portion of the tape presser 28 is wound around the support shaft 20, one end thereof is engaged with the bottom plate 30 of the tension arm 21, and the other end 31 is bent in a bowl shape. Therefore, when the tension arm 21 rotates, the tape presser 28 also rotates. At the time of rotation, the bent portion 31 enters the groove portion 32 at the tip of the tape guide portion 13 on the base side and presses the binding tape T, thereby preventing the binding tape T from being pulled out from the tape reel. . Note that if the binding tape T is completely prevented from being pulled out, it is not possible to cope with an excessive load applied to the binding tape T. Therefore, it is preferable that the tape presser 28 touches the binding tape T via a cushion.

  A magnet 33 is fixed to the lower end of the tension arm 21 on the front end side, so that the tension arm 21 is magnetically attached to the binding machine body 1 even when the binding machine is turned upside down.

  As shown in FIGS. 1 and 9 (a) and 9 (b), the block lever 22 is a triangular member in a side view, and an intermediate portion is pivotally attached to the support shaft 20 and is attached to an end portion on the tape reel side. A roller 34 for suspending the binding tape T is provided. On the other hand, the end on the opposite side is normally positioned so as to overlap the end of the guide groove 26 of the tension arm 21 and the engaging portion 27, and the receiving groove 35 is located at a position corresponding to the end of the guide groove 26. Triangular protrusions (block portions) 36 are formed at positions corresponding to the engaging portions 27 to be formed. Although the receiving groove 35 is aligned with the guide groove 26, as shown in detail in FIG. 2, the projecting piece 36 is configured to enter the engaging portion 27.

  FIG. 10 is a front view of the main part of the binding machine main body showing a state in which the base member 24, the tension arm 21 and the block lever 22 are attached.

  Next, one end of the operating arm 23 is rotatably connected to a support shaft 20 that connects the clincher arm 2 and the handle lever 3. An engagement shaft 37 is provided at the other end, and the engagement shaft 37 is engaged with the guide groove 26 of the tension arm 21. Thus, when the clincher arm 2 is opened and closed by operating the handle lever 3, the engagement shaft 37 slides along the guide groove 26.

  By the way, a first torsion coil spring (first elastic member) 38 is wound around the support shaft 20 of the block lever 22, and the projecting piece 36 is always formed in the guide groove 26 by the first torsion coil spring 38. The engaging shaft 27 of the operating arm 23 is biased so as to prevent the engaging shaft 27 from entering and engaging with the engaging portion 27.

  Similarly, a second torsion coil spring (second elastic member) 39 is wound around the support shaft 20 that connects the tension arm 21 and the clincher arm 2, and the engagement shaft 37 is at the lower end of the guide groove 26. At this time, the tension arm 21 is always urged by the second torsion coil spring 39 so that the engaging shaft 37 enters the engaging portion 27.

  By the way, the front end of the tape guide portion 13 provided at the outlet of the tape reel is disposed close to the rear end portion of the block lever 22. The binding tape T led out from the tape reel is suspended from the end opening of the tape guide portion 5 by the roller 34 at the end of the block lever 22 and the roller 25 at the end of the tension arm 21, and further the binding tape body 1. It is guided by the engagement plate 12 at the tip.

  The biasing force of the second torsion coil spring 39 is set to be smaller than that of the first torsion coil spring 38.

  Next, an operation mode of the pulling back mechanism A of the binding tape T having the above configuration will be described. First, as shown in FIG. 3, when the clincher arm 2 is closed and operated by grasping the handle lever 3, the engaging shaft 37 at the end of the operating arm 23 that responds to the clincher arm 2 is moved to the guide groove of the tension arm 21. 26, the tension arm 21 does not rotate and is held at the initial position. When the clincher arm 2 is closed and operated, the picking plate 17 swings and penetrates the front end of the binding tape T that hangs down in front of the receiving plate 16 and is inserted into the hole of the receiving plate 16 to grasp the end of the binding tape T. . When the handle lever 3 is opened in this state, the clincher arm 2 is opened, and the binding tape T is pulled out from the tape guide portion 5 and opened between the binding machine body 1 and the clincher arm 2 as shown in FIG. Stretched on. At this time, the engagement shaft 37 of the operating arm 23 also slides on the lower end of the guide groove 26. Since the protrusion 36 at the tip of the block lever 22 has entered the engaging portion 27 of the tension arm 21 as shown in FIG. 2, the engaging shaft 37 of the operating arm 23 has entered the engaging portion 27. Can not do it.

  Next, as shown in FIG. 5, an object to be bound P (for example, a vine and a column of a crop) is taken from the outside (left hand side in the drawing) of the binding tape T and is placed between the binding machine main body 1 and the clincher arm 2. When introduced into the space S, the binding tape T stretched between the tip of the binding machine main body 1 and the clincher arm 2 is pulled out from the tape reel. At this time, since the roller 34 at the end of the block lever 22 is pulled out to the front end side of the binding machine body 1, the block lever 22 rotates counterclockwise in the figure against the spring force of the first torsion coil spring 38. To do. When the block lever 22 rotates counterclockwise, the projecting piece 36 at its end is retracted from the engaging portion 27. Since the operating arm 23 is in the initial position of the end of the guide groove 26, when the block by the block lever 22 is released, the operating arm 23 is rotated by the spring force of the second torsion coil spring 39, and the engaging shaft 37 is engaged with the engaging portion. Enter 27. In this state, as shown in FIG. 6, when the handle lever 3 is squeezed again and the clincher arm 2 is operated to close, the engaging shaft 37 at the end of the operating arm 23 responsive thereto engages with the engaging portion 27 of the tension arm 21. As a result, the operating arm 23 moves upward in the drawing and pushes the engaging portion 27 of the tension arm 21 upward, so that the tension arm 21 rotates clockwise about the support shaft 20. As a result, the binding tape T suspended from the tip of the tension arm 21 is pulled back.

  When the tension arm 21 is rotated in the clockwise direction in the figure, the tape presser 28 of the tension arm 21 is also rotated, so that the tip thereof enters the groove portion 32 at the tip of the tape guide portion 13. It is pressed by the tape presser 28 and cannot move. For this reason, the binding tape T moves only in the pullback direction.

  When the clincher arm 2 is closed, as shown in FIG. 11D, the binding tape T is wrapped around the object to be bound and overlaps the clincher groove, and the driver plate 10 and the cutter blade 11 are The driver plate 10 projects and staples the stapled portion of the binding tape T, and simultaneously the cutter blade 11 cuts the original side of the binding portion of the binding tape T. Further, as shown in FIG. 1, the handle lever 3 is opened and the clincher arm 2 is opened to operate to remove the object to be bound P bound by the binding tape T, thereby completing the binding operation and preparing the next binding operation. Is done.

  As described above, according to the pulling back mechanism of the binding tape T, it is possible to eliminate the slack of the binding tape T that is always pulled back and wound around the object to be bound at the time of binding.

  In addition, the pull-back mechanism can be driven by performing a normal bundling operation, so that it can be operated with one hand and is easy to handle.

  Next, in the binding machine, as shown in FIGS. 12 to 14, when the binding tape T stretched between the tip of the binding machine body 1 and the clincher arm 2 is wound around the binding object P. A guide mechanism for projecting the guide member 40 in the space S and engaging the object to be bound P is provided.

  That is, as shown in FIG. 12, the guide mechanism is configured by a guide member 40 provided so as to be able to protrude and retract with respect to the space portion S, and a clincher arm 2 that operates the guide member 40 in the protruding and retracting direction. An intermediate portion of the guide member 40 is rotatably supported by the fixed shaft 19 of the binding machine main body 1, and an L-shaped guide portion 41 is formed at an end located on the tip side of the binding machine main body 1. A portion of the guide member 40 that extends from the portion supported by the fixed shaft 19 to the gripping portion side of the handle lever 3 is bent and is long at the end located on the gripping portion side of the handle lever 3. A hole 42 is formed. A support shaft 14 that rotatably connects the clincher arm 2 and the handle lever 3 is slidably engaged with the elongated hole 42 of the guide member 40.

  According to the above configuration, when the clincher arm 2 is rotated around the support shaft 8 and opened, as in the case shown in FIG. 1, the guide portion 41 of the guide member 40 is bound. It is retracted from the space S formed between the machine main body 1 and the clincher arm 2. Then, as in the case shown in FIG. 3, the handle lever 3 is squeezed to close the clincher arm 2 to operate the clincher arm 2 so that the tip of the binding tape T is gripped by the tip of the clincher arm 2, and then the handle lever 3 is opened. When the clincher arm 2 is opened and operated, the binding tape T is stretched between the binding machine main body 1 and the tip of the clincher arm 2 as shown in FIG. When the clincher arm 2 is closed and opened as described above, the support shaft 14 moves in the vertical direction while sliding along the long hole 42 of the guide member 40 in conjunction with the opening, so that the guide member 40 is also fixed to the fixed shaft 19. The guide portion 41 protrudes into the space S and retreats.

  Therefore, as shown in FIG. 13, the clincher arm 2 is opened and operated, and the object P to be bound is taken from the outside to the inside of the binding tape T and introduced into the space S between the binding machine body 1 and the clincher arm 2. Then, as shown in FIG. 14 again, the binding machine body 1 and the handle lever 3 are squeezed and the clincher arm 2 is closed and operated. At this time, the magazine 6 and the tip of the clincher arm 2 come into contact with each other, and the leading end side and the original side of the binding tape T wound around the object to be bound P overlap on the clincher groove 15. First, the guide member 40 protrudes into the space portion S, and the object P to be bound is engaged with the guide portion 41 at the distal end portion of the guide member 40 and positioned and held at a predetermined position. Then, the binding tape T is pulled back by the pulling back mechanism of the binding tape T described above, and the slack generated when the binding tape T is wound around the binding object P is pulled back. In this way, by holding the object to be bound P on the guide member 41, the binding tape T can be reliably pulled back by the pulling back mechanism of the binding tape T, and the slack can be eliminated.

  In addition, when taking in the to-be-bound material P in the space part S, since the guide member 40 exists in the retracted position retracted from the space part S, it does not become an obstacle at the time of taking-in operation.

  Further, when the clincher arm 2 is operated to be closed with one hand, the guide portion 41 of the guide member 40 automatically protrudes into the space S, so there is no need to bother moving the guide member 40 with the other hand.
