Description

Binding Machine

The present invention relates to a binding machine.

A stapler is used for binding multiple sheets of paper. This type of binding machine usually uses a metal needle. However, the metal needles need to be removed for sorting when the paper is incinerated or placed in a cutter, or when it is collected, which takes time. In addition, in the case of use in food, it is required to avoid the incorporation of iron needles which are foreign bodies. Therefore, there are people who use such non-metal needles made of paper or synthetic resin that do not take any time (see Patent Literature 1 and Patent Literature 2).

This type of binding machine using a non-metallic needle is formed by inserting a paper through a through hole and inserting the paper from one side of the paper. The non-metal needles in the shape of a letter, and the pins of the non-metal needles protruding toward the other side of the paper are bent, thereby binding the paper.

Therefore, the binding machine includes at least: a penetrating mechanism, which is designed to be held in place. The left and right pair of penetrating blades of the non-metal needle of the zigzag shape lift and lower the paper; and the bending mechanism is to bend the pins of the non-metal needle protruding toward the other side of the paper along the other side of the paper and bend the The left and right pins stick to each other.

Furthermore, in order to allow continuous operation, a plurality of non-metallic needles are connected in a flat state, and are formed into band-shaped connecting needles.

Furthermore, the binding machine is made up of a conveying mechanism that conveys the leading end portion of the belt-shaped connecting pin along the conveying path, and a cutting and forming mechanism that removes the leading end portion of the connecting pin that is conveyed by the conveying mechanism, and Metal needles are cut into pieces and formed into Glyph. The non-metal needles cut and formed by the cutting and forming mechanism are filled with the left and right pair of penetrating blades of the penetrating mechanism by the above-mentioned conveying mechanism.

In addition, in order to make the band-shaped connecting pins longer, more compact, and easier to use, they are also wound into a roll. In addition, the binding machine has a structure capable of processing the roller-shaped connecting needle.

However, the binding machine described in this patent document 1 has the following problems.

That is, in order to create a connection pin that can accurately cut non-metallic needles by a cutting and forming mechanism, it is necessary to correctly attach the connection pin to the binding machine body. At this time, if a connecting needle wound into a drum shape is used, it is difficult to correctly attach the connecting needle to the binding machine body due to the influence of the winding habit associated with the connecting needle. In addition, even if the connecting pin is correctly installed, the connecting pin may deviate from the correct position on the binding machine body due to the winding habit after installation. If the connecting pin is deviated from the correct position like this, the connecting pin cannot be accurately cut by the cutting forming mechanism.

For this reason, for example, it is conceivable to store a roller-shaped connecting needle in a needle magazine and mount the needle magazine in a binding machine or the like, thereby indirectly installing the connecting needle in the binding machine body. By using the needle magazine as a medium (smaller and easier to handle than the binding machine) in this way, the connection needle of the needle magazine can be easily installed, and the connection needle can be correctly installed on the binding machine body through the needle magazine. In addition, it is possible to make the connecting needle difficult to shift.

However, in the case of using a needle magazine, the labor time for processing the connected needles increases, and a needle magazine is required. A mechanism for removing and attaching the needle magazine to the stapler is required. Therefore, the structure of the binding machine becomes complicated, the number of components increases, the binding machine becomes large, and the cost becomes expensive.

Further, when the connecting needle is cut into individual non-metal needles by a cutting and forming mechanism, it is necessary to determine the cutting position with high accuracy. Therefore, it is extremely important to correctly position the connecting pin.

Therefore, for example, it is thought to use a relatively strong elastic biasing means such as a metal spring to create a state in which the connecting pin is always pressed on the conveying path from the upper side, and the connecting pin is biased in the conveying direction (front side) to make A contact portion (for example, a penetrating blade of a penetrating mechanism) provided at a position on the front side of the conveying path (the cutting mechanism) pushes the front end portion of the connection pin, thereby positioning (front alignment) of the connection pin.

However, when the front alignment is made in this way, in order to make the feed mechanism that moves backward and forward does not retract the connecting needle, the pressing from the upper side by the elastic biasing means requires excessive pushing force, and the cause of the problem occurs. Application of continuous pressing force in the conveying direction (front side), the problem that the connecting pin (the part pushed by the holding part such as the penetrating blade of the penetrating mechanism) is easily damaged, or the connecting pin is transferred to the cutting mechanism The problem that the resistance becomes larger in time.

Therefore, the present invention has as its main object to solve the above-mentioned problems.

In order to solve this problem, the present invention is a binding machine including: a cutting mechanism that cuts a connecting needle formed by connecting a plurality of flat non-metal needles into each one; and a conveying mechanism that passes the conveying path to the The cutting mechanism conveys the connecting pin; it is characterized in that: the front side of the conveying direction of the conveying path includes a needle holding portion capable of holding the connecting pin; the needle holding portion has: an abutting surface to which the connecting pin is attached; The restricting member restricts the position of the connecting pin from one side; and the disengagement restricting portion is arranged on the other side of the connecting pin and is arranged to make the position different from each other in the forward and backward directions in the conveying direction through the connecting pin. The state confronts this restriction member.

Furthermore, by simply making the leading edge of the connecting pin lightly touch the abutment surface, the restricting member and the release restricting portion of the needle holding portion included on the front side of the conveying path can be used directly without using auxiliary components or the like. Self-holding connecting pin.

Furthermore, in order to solve this problem, the present invention is a binding machine including: a cutting mechanism that cuts a connecting needle formed by connecting a plurality of flat non-metal needles into each one; and a conveying mechanism through the conveying The link is carried to the cutting mechanism by the road; its characteristics are: In the middle of the conveying path, a positioning portion capable of positioning the connecting pin by colliding with the connecting pin driven by the carrying operation of the carrying mechanism is provided.

Furthermore, since the positioning portion directly uses the conveying action of the conveying mechanism to perform the positioning of the connecting needle, a special structured positioning mechanism is not required, and the structure of the positioning portion becomes simple.

According to the present invention, according to this configuration, the connection pin can be simply and surely and accurately mounted, and the size and cost can be reduced. Furthermore, according to the present invention, according to this configuration, the connection pin can be accurately positioned without imposing a load on the connection pin.

First, the "direction" will be described using the perspective view of Fig. 1 (or the side view of Fig. 1A). In this embodiment, the binding machine 1 uses the direction of paper insertion as a reference, the front side as the front, the inner side as the rear, the right side as the right, the left side as the left, the upper side as the upper side, and the lower side as the lower side. That is, it becomes the front-back direction X, the left-right direction Y, and the up-down direction Z. However, the directions are relative.

Next, the needle (binding needle) used in the binding machine 1 will be described using FIG. 2. This needle is a non-metal needle 2 (or soft needle) made of paper or synthetic resin. In addition, the orientation of the non-metal needle 2 will be described with reference to a state in which it is mounted on the binding machine 1.

Glyphs). The non-metallic needle 2 is mounted with the top 2a facing the binding machine 1 in the left-right direction Y, and the left and right pair of pins 2b and 2c are bent toward the lower side inside the binding machine 1. In addition, the non-metallic needle 2 has a desired length (the width of the non-metallic needle 2 or the length in the short-side direction of the non-metallic needle 2) in a pair of front-rear directions X.

Then, as shown in FIG. 3, the left and right pair of pins 2b, 2c are inserted into the through hole p1 of the paper P, and the pins protruding on the back side of the paper P 2b and 2c are sequentially bent inward along the back surface of the paper sheet P, whereby a plurality of paper sheets P can be bound in an overlapping manner. In order to overlap the inwardly bent pins 2b, 2c, the length of the left and right pair of pins 2b, 2c added is set to be longer than the top 2a.

At this time, the inner surface (or the back surface) of the pin 2c which is bent inward later is provided to bend the pins 2b and 2c inward along the back surface of the paper P, so as to be adhesively fixed to the first inwardly bent An adhesive portion 2d on the outer surface (or surface) of the bent pin 2b. On the other hand, at least the outer surface (or surface) of the non-metallic pin 2 that is bent inward at least later is implemented so that it does not (when the non-metallic pin 2 is wound into a roll shape or overlaps up and down) Non-adhesive processing where the adhered portion 2d is adhered.

In addition, as shown in FIG. 4, in order to allow continuous operation, the non-metallic needle 2 is connected to a plurality of branches while being extended in a flat state, and is formed into a band-shaped connection needle 3 (or a soft connection needle).

A substantially horizontal seating surface 76a is provided at a front end portion of the guide protrusion 76 when the binding needle cover 33 is attached to the binding machine 1 in a linear contact state with the seating portion 77c (seat).

Furthermore, the upper part 78 of the cover guide 75 formed in a groove shape has an introduction tapered portion 78a that descends forward on the near side (rear side), and has a traverse portion 77a (lower traverse portion) inside the introduction tapered portion 78a. A substantially parallel traverse portion 78b (upper traverse portion) has a slanted portion 77b on the inner side of the traverse portion 78b, a substantially parallel slanted portion 78c, and a terminal portion 78d on the inner side of the slanted portion 78c that is substantially parallel to the seating portion 77c. .

Furthermore, as shown in FIG. 31 (a), the entry side traverse portion 77a and the introduction cone portion 78a can be inserted obliquely in order to set the stapling needle cover 33 in a forward lowered state, and make it as wide as possible. A tapered groove portion that gradually narrows on the front side.

In addition, the middle traverse portion 77a and the traverse portion 78b are arranged so that the posture of the staple cover 33 is not lowered obliquely from the front as shown in FIG. 31 (a). When the state is changed to the horizontal state as shown in FIG. 31 (b), it is impossible to enter, and becomes a horizontal interval 79a narrower than the height of the guide projection 76 in the up-down direction Z when the staple cover 33 is set to the forward lowered state. Move the groove section. In addition, the entrance side (the tapered groove portion) of the cover guide 75 is gradually reduced in height to become the interval 79a.

Further, as shown in FIG. 31 (b), the stapling needle cover 33 between the inwardly inclined portion 77b and the inclined portion 78c is in a substantially horizontal state, and then falls down along the inclined portion 77b to become the guide protrusion 76 itself. The thickness of the descending inclined grooves is approximately the same at intervals of 79b.

Finally, as shown in FIG. 31 (c), the position between the inner seating portion 77c and the terminal portion 78d is such that the position of the guide protrusion 76 in the up-down direction Z can be restricted in a state where the staple cover 33 is installed. The holding groove portion is a holding groove portion at a distance of 79c which is substantially the same as the height of the guide protrusion 76 inclined in the up-down direction Z when the staple cover 33 is set to a horizontal state.

In this way, when the binding needle cover 33 is seated into the inside and dropped into the inside, when the binding needle cover 33 is mounted on the binding machine 1, for example, the protrusion for protecting the needle from the front end of the binding needle cover 33 can be prevented. The guide protrusion 71a protruding from 71, the locking surface 72a of the first check pawl 72, or the locking surface 73a of the second check pawl 73 rubs the upper surface of the connecting needle 3 forward, and is forced by the guide protrusion 71a Defective movement of the connecting needle 3 forward.

[Regarding the positioning structure of the connecting pin 3]

When the connecting needles 3 are cut into individual non-metal needles 2 by a cutting mechanism (or a cutting forming mechanism 35), the cutting position needs to be determined with high precision. Therefore, it is extremely important to accurately position the connection needle 3.

Therefore, for example, it is conceivable to use a relatively strong elastic biasing means such as a metal spring, to always set the connecting pin 3 on the conveying path 32 to be pressed from the upper side, and to move the connecting pin 3 in the conveying direction (previously). (Side) is biased, and the front end portion of the connecting pin 3 is always pressed against a contact portion (for example, a penetrating blade 36, etc.) provided inside the conveying path 32 (the cutting mechanism), thereby performing the connecting pin 3 Positioning (front alignment).

However, if the front alignment is performed in this way, in order to prevent the connecting needle 3 from moving backward when the forward-moving conveying mechanism 34 is retracted, the pressing from the upper side by the elastic biasing means requires an excessive pushing force, and the cause The application of a continuous pressing force in the conveying direction (front side) causes a problem that the connecting pin 3 (the part pressed by the abutment portion (penetrating blade 36, etc.)) is easily damaged, or is conveyed to the cutting mechanism. The problem that the resistance when the needle 3 is connected is increased.

Therefore, in this embodiment, positioning of the connection needle 3 is performed as described below.

(Composition 1) As described above, the binding machine 1 of this embodiment includes a cutting mechanism that cuts the connecting pins 3 formed by connecting a plurality of flat non-metal needles 2 to each other; and the conveying mechanism 34 , The connecting needle 3 is conveyed to the cutting mechanism via a conveying path 32.

Further, in the middle of the conveyance path 32, a positioning portion 81 capable of positioning the connection pin 3 by collision of the connection pin 3 moved by the conveyance operation of the conveyance mechanism 34 is provided.

Here, the cutting mechanism is the above-mentioned cutting forming mechanism 35. The middle of the conveyance path 32 may be anywhere as long as it is within the range of the conveyance path 32. The conveying operation of the conveying mechanism 34 can include the movement of the feed connection pin 3 or the feeding operation. Preparatory actions (such as a pause or return motion) accompanying the action of the connecting pin 3. The positioning unit 81 may be any person who can position the connecting pin 3 only by touching the connecting pin 3 as long as the connecting pin 3 is moved by the carrying mechanism 34.

(Effect 1) In this configuration, the positioning portion 81 is provided in the middle of the conveying path 32, and the connecting pin 3 is moved by the conveying operation of the conveying mechanism 34 to collide with the positioning portion 81 to position the connecting pin 3. With this positioning portion 81, the positioning operation of the transfer mechanism 34 can be directly used to position the connecting needle 3. The positioning mechanism 81 can be made simple without the need for a positioning mechanism having a special configuration. Therefore, the connection pin 3 can be accurately positioned without burdening the connection pin 3.

(Configuration 2) Specifically, as shown in FIG. 27, the positioning portion 81 is positioned at a position closer to the rear side of the conveying direction than the front end portion of the connecting pin 3 in the conveying direction.

Further, the positioning portion 81 may be used to position the connection pin 3 by pressing the connection pin 3 in a direction toward the rear side of the conveying direction.

Here, the conveyance direction is the front side of the front-rear direction X. The direction to the rear of the conveyance direction is the rear of the front-rear direction X. The position closer to the rear side in the conveying direction than the front end of the connecting needle 3 is the position of the non-metallic needle 2 after the second branch before the connecting needle 3. In this case, the position of the third non-metallic needle 2 before the connecting needle 3 is adopted. As the positioning portion 81, the first check pawl 72 (the locking surface 72a facing the front side in the vertical direction Z) of the binding needle cover 33 described above can be used.

In addition, the second retaining claw 73 (the locking surface 73a facing the vertical direction Z) of the binding needle cover 33 in FIG. 28 can also be used as the positioning portion 81 when the connecting needle 3 has two remaining needles. The second non-metallic pin 2 of the connecting pin 3 Positioning. By the way, as shown in FIG. 29, when the connecting pin 3 becomes one, there is no need to cut, so the positioning system is unnecessary.

(Effect 2) In this configuration, a positioning portion 81 for positioning is provided at a position closer to the rear side than the front end portion of the connecting pin 3 in the conveying direction in the middle of the conveying path 32, and the orientation of the positioning portion 81 is conveyed to the middle The direction (returning direction) of the rear direction (temporarily before the cutting of the connecting pin 3) is temporarily pushed to perform positioning (back alignment) of the connecting pin 3. Therefore, since it is not necessary to provide a relatively strong elastic biasing means such as a metal spring to continuously press the connecting pin from the upper side, an excessive and continuous pressing force does not act on the connecting pin 3, and the connection The needle 3 is difficult to damage, and the resistance when the connecting needle 3 is transported to the cutting mechanism can be eliminated, and the non-metal needle 2 with a softer material can be transported.

(Configuration 3) The positioning portion 81 can be positioned so as to be in contact with an edge portion of the hole portion 4 provided in the non-metallic needle 2 or the connecting needle 3 toward the rear side in the conveying direction.

Here, the hole portion 4 is used as a positioning hole. The edge portion of the hole portion 4 on the rear side facing in the conveying direction comes into contact with the locking surface 72a on the front side of the positioning portion 81 (first check pawl 72) and is positioned. The positioning holes can be shared with the feed holes. However, it is also possible to provide a positioning hole and a feed hole separately, respectively.

In the case of this embodiment, the first hole portion 4 and the second hole portion 4 before the connecting pin 3 are used as the feed holes, and the third hole portion 4 in the front is used as the positioning hole. The hole portions 4 provided at the same position in the left-right direction Y are used flexibly to prevent the first check claw 72 and the feed claw 62 from interfering with each other.

(Effect 3) According to this configuration, with a simple configuration, the positioning of the connection needle 3 can be surely performed. In addition, the hole portion 4 such as a feed hole is set in advance. Since the connection pin 3 is provided, the hole portion 4 can be directly used for positioning the connection pin 3. In addition, the hole portion 4 may be provided with a dedicated positioning member separately from the feed hole.

(Configuration 4) Alternatively, the positioning portion 81 may be positioned by using the edge portions of the non-metallic needle 2 in a state of being flatly extended toward the rear side in the conveying direction.

Here, the edge portions facing the rear side of the both ends of the non-metallic needle 2 may be tapered slit portions 3b provided at the rear edge portions of both ends of the non-metallic needle 2 (in this case, the first The hole 4 in Fig. 27 is replaced with a slit 3b). The slit portion 3 b of the trailing edge portion of the non-metal needle 2 is positioned in contact with the locking surface 72 a on the front side of the positioning portion 81. In addition, the positioning portion 81 in this case is not particularly illustrated, and for example, the first check pawl 72 or the same may be provided at the position of the slit portion 3b.

(Effect 4) According to this configuration, the positioning of the connection needle 3 can be reliably performed with a simple configuration. In addition, since both ends of the connecting pin 3 are provided in advance with the leading edge portion and the trailing edge portion, the through holes p1 formed in the paper P are easily inserted and bent so as to be bent. The tapered slits 3 b of the stitches 2 b and 2 c of the non-metallic needle 2 in a zigzag shape can directly use the slit 3 b of the trailing edge portion for positioning of the connecting needle 3.

(Configuration 5) The conveying mechanism 34 includes a returning unit 82 that temporarily cuts the connecting pin 3 toward the rear of the conveying direction when the connecting pin 3 is cut by the cutting mechanism (cutting forming mechanism 35). The direction is biased, and the connecting pin 3 is pressed against the positioning portion 81.

Here, the returning portion 82 may be the feed claw 62 of the push rod 61 of the conveying mechanism 34. The feed claw 62 is a bag for the front end of the arm extending forward Including a claw portion, the claw portion has a locking surface 62a extending in the up-down direction Z on the front side and a slope 62b that descends on the rear side.

(Effect 5) As described above, the feed claw 62 of the pusher 61 is temporarily retracted from the forward state when the connecting pin 3 is fed, but at this time, the hole 4 (or Seam portion 3b. Hereinafter, it will be described as hole portion 4.) It is displaced backward, and the claw portion is guided downward along the inclined surface 62b. The feeding claw 62 is elastically deformed downward, and the claw portion at the front end is the first hole from the front. Section 4 comes out. Then, it is retracted along the back surface of the connecting pin 3 to enter the second hole portion 4. At this time, as shown in FIG. 42D, (the small convex portion 67 for locking of the stapler main body 5 (the guide portion 66) is locked by the guide arm 65 of the pusher 61) in the retracted state lock.

When the pusher 61 starts to retreat in this manner, the rear edge portion of the hole portion 4 on the front side is pushed backward by the inclined surface 62b of the feed claw 62, and only when the feed claw 62 is released from the hole portion 4 on the front side is extremely short. For a period of time, the connecting needle 3 is biased so as to slightly retract to the rear side. Further, by using a slight movement of the connecting pin 3 at this time, the connecting pin 3 can be pressed against the positioning portion 81 and positioned. By this positioning, the burden on the connecting pin 3 is reduced, and the cutting of the connecting pin 3 can be performed accurately by the cutting mechanism.

Therefore, it is only necessary to temporarily perform positioning only when cutting by the cutting mechanism, and the mechanical load required for positioning becomes lighter, and the positioning operation can be performed by the preliminary operation (backward movement) required to transport the connecting needle 3 by the transport mechanism 34. Since the return claw 82 can directly use the feed claw 62 of the conveyance mechanism 34, it is also simple in structure.

(Configuration 6) The positioning portion 81 has locking surfaces 72a and 73a, and the locking The surfaces 72a and 73a are when the conveying mechanism 34 biases the non-metallic needle 2 or the connecting needle 3 toward the rear side of the conveying direction, and touches the edge portion of the non-metallic needle 2 or the connecting needle 3 behind the conveying direction. .

(Effect 6) As described above, when the positioning portion 81 has the locking surfaces 72a and 73a, when the conveying mechanism 34 biases the non-metallic needle 2 or the connecting needle 3 toward the rear side of the conveying direction, it is possible to make The edge portions on the rear side of the non-metallic needle 2 or the connecting needle 3 in the conveying direction surely touch the locking surfaces 72a and 73a. Position it.

(Configuration 7) Alternatively, as shown in FIG. 27B (FIG. 27C), the positioning portion 81 is positioned at a position closer to the rear side of the transportation direction than the front end portion of the connection needle 3 in the transportation direction.

Further, the positioning portion 81 may be used to position the connection pin 3 by pressing the connection pin toward the front side in the conveying direction.

Here, the position of the connecting needle 3 closer to the rear side in the conveying direction than the front end portion is the position of the non-metallic needle 2 of the connecting needle 3 from the front to the second and subsequent positions. In this case, the position of the non-metallic needle 2 of the third branch from the front of the connecting needle 3 is adopted. For the positioning portion 81, for example, the first check pawl 72 having the locking surface 72c facing the rear side in the vertical direction Z provided on the staple cover 33 can be used. The positioning portion 81 may use the first check pawl 72 of the staple cover 33 or may be provided with the same one as the first check pawl 72.

(Effect 7) In this configuration, a positioning portion 81 is provided in the middle of the conveying path 32 to position the connecting needle 3 closer to the rear side than the front end portion in the conveying direction, and the positioning portion by the conveying mechanism 34 is used. 81, toward the direction (feed direction) toward the front side of the transport direction of the connecting needle 3 (feeding is about to (Before the end) is temporarily pushed to perform positioning (front alignment) of the connecting needle. After the feeding of the connecting pin 3 is completed and the next feeding is performed, the feeding operation by the transport mechanism 34 is suspended, and the forward movement of the connecting pin 3 is also stopped. Therefore, since it is not necessary to provide a relatively strong elastic biasing means such as a metal spring to continuously hold the connecting pin 3 from the upper side, an excessive and continuous pressing force does not act on the connecting pin 3, and The connecting pin 3 is difficult to be damaged, and the resistance when the connecting pin 3 is transported to the cutting mechanism can be eliminated, and the non-metallic pin 2 with a softer material can be transported.

(Configuration 8) The positioning portion 81 can be positioned by touching an edge portion of the hole portion 4 provided on the non-metallic needle 2 or the connecting needle 3 toward the front side in the conveying direction.

Here, the hole portion 4 is used as a positioning hole. An edge portion of the hole portion 4 on the front side facing the conveyance direction comes into contact with the locking surface 72c on the rear side of the positioning portion 81 (first check pawl 72) and is positioned. The positioning holes can be shared with the feed holes. However, it is also possible to provide a positioning hole and a feed hole separately, respectively.

In the case of this embodiment, the first hole portion 4 and the second hole portion 4 of the connecting pin 3 are used as the feed holes from the front, and the third hole portion 4 from the front is used as the positioning hole. The hole portions 4 provided at the same positions in the left-right direction Y are used differently to prevent the first check claw 72 and the feed claw 62 from interfering with each other.

(Effective effect 8) According to this configuration, the positioning of the connection needle 3 can be surely performed with a simple configuration. In addition, since the hole portion 4 such as a feed hole is provided in the connection pin 3 in advance, the hole portion 4 can be directly used for positioning the connection pin 3. In addition, the hole portion 4 may be provided with a dedicated positioning member separately from the feed hole.

(Composition 9) Alternatively, the positioning portion 81 may be extended to touch flatly. The non-metallic needle 2 in the extended state is positioned at the edge portions facing the front side in the conveying direction.

Here, the edge portions facing the front side of both ends of the non-metal needle 2 may be tapered slit portions 3b provided in the front edge portions of both ends of the non-metal needle 2 (in this case, the first The hole 4 in Fig. 27B is replaced with a slit 3b). The slit portion 3b of the leading edge portion of the non-metal needle 2 is positioned in contact with the locking surface 72c on the rear side of the positioning portion 81. In addition, the positioning portion 81 in this case is not particularly shown, and for example, the first check pawl 72 or the same may be provided at the position of the slit portion 3b.

(Effective effect 9) According to this configuration, the positioning of the connection needle 3 can be surely performed with a simple configuration. In addition, since both ends of the connecting needle 3 are provided in advance with the leading edge portion and the trailing edge portion, the through-holes p1 formed in the paper P are easily inserted and bent. The tapered slits 3 b of the pins 2 b and 2 c of the non-metallic needle 2 in a zigzag shape can directly use the slit 3 b of the leading edge portion for positioning the connecting needle 3.

(Composition 10) The conveying mechanism 34 is configured to include a pressing portion 83 that biases the connecting needle 3 toward the front side of the conveying direction of the connecting needle 3 when the connecting needle 3 is fed by the conveying mechanism 34. The connection needle 3 is pressed against the positioning portion 81.

Here, the pressing portion 83 may be a feed claw 62 of a push rod 61 of the conveyance mechanism 34. In this case, the feed claw 62 includes a claw portion at the front end portion of the arm extending forward, and the claw portion has a rearwardly rising slope 62c on the front side and a rearwardly decreasing slope 62b on the rear side. The front side of the claw portion of the feed claw 62 can also use a locking surface 62a extending in the up and down direction. However, by using a slope 62c with a rear rising on the front side, some margin can be ensured during front alignment, and it can be slowed down. And overwhelming. In addition, the feed claw 62 is designed to avoid shifting the position of the positioned connecting needle 3 to the rear side due to contact with the connecting needle 3 (the rear edge portion of the middle hole portion 4 or the slit portion 3b) during the backward movement. It is better to back off immediately below (refer to the arrow in Figure 27C).

(Effect 10) As described above, the feed claw 62 of the pusher 61 advances when the connecting pin 3 is fed, but at this time, the hole portion 4 (or the slit portion 3b) is pushed forward by the front slope 62c. (Hereinafter, it is described as the hole part 4), and the feed claw 62 biases the connecting needle 3 forward. Then, by using the movement of the connecting pin 3 at this time, the connecting pin 3 can be pressed against the positioning portion 81 to perform positioning. With this positioning, the burden on the connecting pin 3 can be lightened, and accurate cutting of the connecting pin 3 can be performed by a cutting mechanism.

Therefore, it is only necessary to perform positioning only when the connecting needle 3 is fed by the conveyance mechanism 34, and the burden on the mechanism required for positioning becomes lighter. The pressing portion 83 is also simple in construction because it is possible to use the feed claw 62 of the conveyance mechanism 34.

(Composition 11) The positioning portion 81 has a locking surface 72c that touches the non-metal needle 2 or the connection when the conveying mechanism 34 biases the non-metal needle 2 or the connecting needle 3 to the front side in the conveying direction. The edge of the needle 3 facing the front side in the conveying direction.

(Effect 11) As described above, the positioning portion 81 has the above-mentioned locking surface 72c. When the conveying mechanism 34 biases the non-metallic needle 2 or the connecting needle 3 toward the front side in the conveying direction, the non-metallic needle can be made. 2 or the edge portion of the connecting pin 3 on the front side facing the conveying direction surely touches the locking surface 72c to perform positioning. In addition, the positioning portion 81 is formed so as to prevent the feed from being hindered by the feed link pin 3. The non-metallic needle 2 or the connecting needle 3 is temporarily retracted. The positioning portion 81 may be provided with a downwardly descending slope 72d on the front side.

[About the self-holding structure of the connecting pin 3]

In order to produce the connecting pin 3 that can accurately cut the non-metallic pin 2 by the cutting mechanism, it is necessary to correctly attach the connecting pin 3 to the binding machine body 5. At this time, if the connecting needle 3 wound in a roll shape is used, it is difficult to accurately attach the connecting needle 3 to the binding machine body 5 due to the influence of the winding habit associated with the connecting needle 3. In addition, even if the connecting pin 3 is correctly installed, the connecting pin 3 may be deviated from the correct position on the binding machine main body 5 due to the winding habit after installation. If the connecting pin 3 deviates from the correct position like this, the connecting pin 3 cannot be accurately cut by the cutting mechanism.

For this reason, for example, it is conceivable to store the roller-shaped connecting needle 3 in a needle magazine and mount the needle magazine on the binding machine 1 or the like to thereby indirectly attach the connecting needle 3 to the binding machine body 5. By using the needle magazine as a medium (smaller and easier to handle than the binding machine 1) in this way, the attachment of the connecting needle 3 of the needle magazine becomes easy, and the connecting needle 3 can be correctly installed in the binding through the needle magazine. The machine body 5 also makes it difficult to shift the connecting pin 3.

However, in the case of using a needle magazine, the labor time for processing the connecting needle 3 caused by the removal and installation of the needle magazine increases, and a needle magazine or a mechanism for removing and attaching the needle magazine to the binding machine 1 is required. Therefore, the structure of the binding machine 1 becomes complicated, and the number of components increases, and the binding machine 1 becomes large and expensive.

Therefore, in this embodiment, as described below, the binding needle 3 can be directly and accurately attached to the binding machine body 5.

(Structure 1) As described above, the binding machine 1 of this embodiment includes a cutting mechanism, which is a coupling formed by connecting a plurality of non-metal needles 2 in a flat state. The knotted needles 3 are cut into one piece, and the transfer mechanism 34 transfers the connecting needles 3 to the cutting mechanism via the transfer path 32.

Further, as shown in Fig. 32 (~ Fig. 35), the front side of the conveying path 32 in the conveying direction is formed to include a needle holding portion 84 that can hold the front end of the connecting needle 3 or its vicinity.

As shown in FIG. 33, the needle holding portion 84 includes: an abutment surface 85 for attaching the connecting needle 3; a restricting member 87 for restricting the position of the connecting needle 3 from one side; and a release restricting portion 88, It is attached to the other surface side of the connection pin 3, and is arranged to face the restricting member 87 in a state where the position is different from each other in the transport direction through the connection pin 3.

In addition, in this embodiment, as an example, one surface side is regarded as the side related to the connection pin 3, the conveying path constituting member 51 or the restriction member 87, that is, the lower side of the connection pin 3, and the other side is regarded as the connection side. The path constituting member 51 faces, for example, the side of the binding needle cover 33 or the needle holding portion 84, that is, the upper side of the connecting needle 3. However, the above may be reversed.

Here, the needle holding portion 84 is a portion that holds the front end side of the connecting needle 3 and is provided at positions on both sides of the connecting needle 3, respectively. The binding needle main body 5 securely holds the connecting needle 3 by itself, and If necessary, it is preferable to easily remove the connecting needle 3 from the binding machine body 5. The self-holding system does not use other structures such as a needle magazine, and can only hold the front end portion of the connecting needle 3 or the vicinity of the binding body 3 in advance by only the needle holding portion 84.

The contact surface 85 is any part of the front end side of the connecting needle 3 when the front end of the connecting needle 3 is inserted into the conveying path 32, for example, the front edge of the non-metal needle 2 after the first or second branch touches the lightly. can. On the cling surface 85, such as As shown in Fig. 34 and Fig. 35, the penetration blade 36 of the penetration mechanism 37 can be used. The contact surface 85 is, for example, as shown in FIGS. 36 to 36C, and can be provided on the conveyance path constituent member 51.

Specifically, for example, in FIG. 36, the abutting surface 85 is formed at the position of the cut-out connecting portion 3a which is close to the leading edge of the connecting pin 3 (the first non-metallic pin 2). In FIG. 36A, the abutment surface 85 is formed at a position close to the inclined slit portion 3b of the leading edge of the connecting needle 3 (the first non-metal needle 2). In FIG. 36B, the abutment surface 85 is formed as a stepped notch 3d that abuts on a portion of the slit portion 3b provided at the leading edge of the connecting needle 3 (the first non-metal needle 2). Furthermore, in FIG. 36C, the abutment surface 85 is made to abut the slit portion 3b (inside) of the vicinity of the front portion (the second non-metal needle 2) of the connecting needle 3. In addition, in each case, the abutting surface 85 is shaped so as to match the shape of the abutted portion of the connecting needle 3. In the case of FIG. 36C, the abutment surface 85 is a protruding portion protruding upward from the upper surface of the conveyance path 32. The protruding portion serving as the abutment surface 85 can be provided on the upper surface of the conveyance path 32 so as to protrude and be accommodated freely.

Alternatively, the sticking surface 85 may be provided on the binding machine body 5 as shown in FIG. 37, for example.

The restriction member 87 is provided for restricting the position of the connecting needle 3 from one surface side. The restricting member 87 is, for example, a holding member configured to contact the connecting pin 3 from one side and hold the position of the connecting pin 3, or a return preventing member that can prevent or prevent the connecting pin 3 from returning to the rear side in the conveying direction.

Specifically, as shown in FIG. 33, the restricting member 87 may be a card that is engaged with the engaging portion 86 provided on the connecting pin 3 from one side of the connecting pin 3. An engaging member that can hold the position and prevent the return position when closed. As the engaging portion 86, the hole portion 4 of the connection needle 3, the slit portion 3b on both sides, and the like can be used. As the engaging member, a feed claw 62 or the like of the transport mechanism 34 can be used.

As shown in FIG. 33A and FIG. 33B, the restricting member 87 may be a rolling member 87a provided with rolling along one surface side of the connecting pin 3. The rolling member 87a is rotatably supported by an upper end portion of an arm 87b extending upward from the lower direction provided on the lower side of the connecting pin 3, and is pivotally supported via a rotating shaft 87c extending in the left-right direction Y. At this time, the rolling member 87a is made of a friction wheel made of rubber or the like, or a unidirectional roller that allows rotation only in the direction in which the connecting pin 3 is fed forward, can easily hold the position or prevent return. When the restricting member 87 is used as the rolling member 87a, as shown in FIG. 33A, the rolling member 87a is provided at a position that does not interfere with the feed claw 62 in the left-right direction Y, or, as shown in FIG. 33B, The feed claws 62 are provided so as to be staggered in the conveying direction (rearward side) of the rolling member 87a. In addition, the rolling member 87a is a driven wheel that rotates with the movement of the connecting pin 3 toward the front side in the conveying direction, but may be a driving wheel that is driven by a driving mechanism. When the rolling member 87a is used as a driving wheel, the feed claw 62 may not be necessary.

In this case, the restriction member 87 is provided on the lower surface side of the connection needle 3. The detachment restriction portion 88 is the upper surface side of the connecting needle 3. However, the positional relationship between the restriction member 87 and the separation restriction portion 88 may be reversed up and down. The detachment restricting portion 88 is preferably provided in a state staggered from at least one or both of the front side and the rear side of the restricting member 87. The separation restriction section 88 will be described later.

(Effect 1) According to this structure, only the front end of the roller-shaped connecting needle 3 accommodated in the accommodating portion 31 is pulled out, and the connecting needle 3 is pulled out. The front end is inserted into the inside (front side) of the conveying path 32 to slide along the conveying path 32, and the leading edge of the connecting pin 3 lightly touches the abutting surface 85. The needle holding portion 84 included in the front side of the conveying path 32 is used. The restriction member 87 on one side and the separation restriction portion 88 on the other side can directly hold the front end portion of the binding needle 3 or the vicinity thereof to the binding machine body 5 without using an auxiliary element or the like.

At this time, the tip of the connecting pin 3 is inserted into the conveying path 32 with only one finger, and the connecting pin 3 can be simply and surely mounted without any deviation in the conveying direction (front-rear direction X) without depending on visual observation. In addition, the contact surface 85 of the needle holding portion 84 can also prevent the occurrence of bending of the connecting needle 3 caused by excessive insertion of the connecting needle 3.

As a result, installation errors such as deviations in the conveying direction and the like caused by the winding habit of the connecting pin 3 wound into a drum shape can be eliminated, so that labor time for reassembly can be saved, and it is not necessary to properly install the connecting pin 3 on The binding machine 1 is provided as a different component (for indirectly receiving the holding roller-shaped connecting pin 3) needle magazine, or the needle magazine is to be stored in the space of the binding machine 1, or the needle is disassembled and attached to the binding machine 1. The mechanism of the cassette reduces the labor time for processing the connecting needle 3, and greatly simplifies the structure of the binding machine 1. The size of the binding machine 1, the number of components, or the cost can be reduced.

(Configuration 2) The detachment restricting portion 88 is a first restricting portion 91 having a position of the non-metallic needle 2 provided at the front end of the connecting needle 3.

Here, since the non-metallic needle 2 connected to the front of the needle 3 is inserted into the cutting and forming mechanism 35, the first restricting portion 91 can be provided on the presser plate 92 of the cutting and forming mechanism 35 shown in FIG. 32. Inside.

The first restricting portion 91 may be provided as shown in FIG. 36, for example. Placed on the conveying path constituting member 51.

(Effect 2) According to this configuration, the position of the non-metallic needle 2 in front of the connecting needle 3 can be reliably restricted by the first restricting portion 91, and can be held so as not to come off. This first restricting portion 91 is effective for preventing the bending of the connecting pin 3 after the front edge of the connecting pin 3 (the non-metallic pin 2 on the front end) touches the contact surface 85. In addition, by providing the first restricting portion 91, the contact surface 85 is in a state in which the end portion is difficult to bend before the connecting needle 3, so that the hand reaction becomes more severe when touching (in contrast to the contact surface in a bent state). At 85 o'clock, it is clear that the tip of the connecting needle 3 is surely held by the detachment restricting portion 88 based on the hand response.

(Configuration 3) The detachment restricting portion 88 may include a second restricting portion 93 provided at a position of the non-metallic needle 2 after the second branch of the connecting needle 3.

In addition, the restricting member 87 is prepared to be disposed between the first restricting portion 91 and the second restricting portion 93 in the conveying direction of the connecting pin 3.

Here, the second restricting portion 93 may be an upper edge portion (located on both sides of the first recessed portion 55 and the second recessed portion 56) of the needle opening 54 provided in the vertical wall portion 52 of the conveying path constituting member 51.

In this case, in FIG. 33, the engaging member serving as the restricting member 87 is used as the claw portion of the feed claw 62 fitted to the first hole portion 4 from the front. The first hole portion 4 is slightly forward, and the second restricting portion 93 is located slightly rearward than the first hole portion 4.

In this case, as shown in FIG. 35, the first restricting portion 91 and the second restricting portion 93 are provided on the outer side in the left-right direction Y than the restricting member 87 (the claw portion of the feeding claw 62). The first restricting portion 91 and the second restricting portion 93 are structured, and only one of them may be provided.

The second restricting portion 93 is, for example, as shown in FIG. 36, and may be provided on the conveyance path constituent member 51. The second restricting portion 93 is, for example, as shown in FIG. 33C, and can be formed on the lower end portion of the arm 93b provided from the upper side to the lower side of the connecting pin 3 (for example, the upper surface side) and having a via A rolling member 93a pivotally supported by a rotating shaft 93c extending in the left-right direction Y. This rolling member 93a is made to roll along the other surface side of the connection pin 3. At this time, the rolling member 93a is made of a friction wheel made of rubber or the like, or a unidirectional roller that is allowed to rotate only in the feed direction forward to the conveying direction, thereby making it possible to easily maintain or check the position. Or prevent detachment. The rolling member 93a is a driven wheel that rotates with the movement of the connecting pin 3 toward the front side in the conveying direction, but it can also be a driving wheel that is driven by a driving mechanism.

(Effect 3) According to this configuration, by the second restricting portion 93, the position of the non-metallic needle 2 after the second branch of the connecting needle 3 can be reliably restricted and held so as not to be detached, and it can be borrowed from the upper side. The first restricting portion 91, the second restricting portion 93, and the lower restricting member 87 can hold the front end portion of the connecting needle 3 or its vicinity in a zigzag manner from above and below. As a result, since a higher self-holding force can be obtained, it is possible to make it difficult for the attached pin 3 to be separated from the conveyance path 32. This second restricting portion 93 is effective for the connection pin 3 having a winding habit, and is effective for preventing positional deviation caused by the winding habit.

(Configuration 4) As shown in FIG. 33, the detachment restricting portion 88 is disposed so as to have gaps 95 and 96 separately from the other surface of the connecting pin 3.

The restricting member 87 is formed as an engaging member that engages with the engaging portion 86 provided on the connecting pin 3 from one side of the connecting pin 3.

The front end portion of the restricting member 87 is made to pass through the engaging portion 86 to The other side of the connecting needle 3 protrudes to be larger than the above-mentioned gaps 95 and 96 (amount of protrusion 97> gaps 95 and 96).

(Effect 4) The separation restricting portion 88 is arranged to have the gaps 95 and 96 separately from the other surface of the connecting pin 3. Thereby, the connection pin 3 without the winding entanglement can be prevented from coming into contact with the connection pin 3 while preventing the detachment restriction portion 88 from being directly contacted with the connection pin 3, and can be held so as not to come off. In addition, with respect to the connection pin 3 having a winding habit, the detachment restricting portion 88 directly touches the connection pin 3 or the like lightly, and the front end portion of the connection pin 3 can be held.

As a result, damage to the connecting needle 3 can be eliminated, and the conveyance resistance to the connecting needle 3 can be reduced.

When the restricting member 87 is used as the engaging member, the distal end portion of the engaging member passes through the engaging portion 86 and protrudes to the other surface side of the connection pin 3 to be larger than the gaps 95 and 96 described above. Accordingly, since the front end portion of the connecting pin 3 passing through the narrow gaps 95 and 96 between the detachment restricting portion 88 and the other surface of the connecting pin 3 is difficult to pass over the restricting member 87, the connecting pin 3 is more reliably restricted and held in place. It does not come off, and it is possible to effectively prevent the connecting needle 3 from coming off the conveyance path 32.

In addition, since the feed claw 62 as the engaging member (restriction member 87) has a rearwardly descending inclined surface 62b on the rear side of the claw portion of the front end and a locking surface 62a on the front side in the up-down direction Z, When the front end portion of the connecting pin 3 is inserted sideways, the inclined surface 62b can be easily crossed, and the locking surface 62a is difficult to be crossed when standing back, and the structure can be easily installed and difficult to disengage.

However, in the case of removing the connecting pin 3, as shown in FIG. 38, it is required to be made stronger than the force acting on the connecting pin 3 when the connecting pin 3 naturally leaves the conveying path 32 due to the winding habit. Pull the connecting pin 3 backward. So with the needle The holding portion 84 is provided at a position connecting both sides of the needle 3, and the first recessed portion 55 and the first recessed portion 55 of the vertical wall portion 52 are provided between the second restricting portion 93 (needle opening 54) on the left and right of the needle holding portion 84. Since the connecting pin 3 can be bent in a middle-high state toward the out-of-plane direction (upward) of the two recessed portions 56, the connecting pin 3 can be intentionally removed from the needle holding portion 84 by the bending of the connecting pin 3.

Hereinafter, the main parts of the binding machine 1 will be described using FIGS. 39 to 52.

[About cutting and forming mechanism 35]

As shown in FIG. 39, the above-mentioned cutting and forming mechanism 35 includes a cutting blade 101 (cutting mechanism) that cuts the non-metallic needle 2 from the connecting needle 3 into one branch, and a pair of left and right forming members 102 (forming mechanism) Is formed by forming a flat non-metallic needle 2 Zigzag; and pressure plate 92 (pressure needle mechanism), the retention should be maintained Formation of the shape of the glyph Pins 2b, 2c of the non-metallic pin 2 in a zigzag shape. In addition, the receiving seat 58 (refer to FIG. 38) of the conveying path constituting member 51 described above also functions as a supporting portion (fixing portion) that supports the non-metallic needle 2 during forming, and becomes one of the constituting members of the cutting and forming mechanism 35. In addition, as long as the non-metallic needle 2 can be supported during molding, the support portion is not limited to a configuration such as the receiving seat 58.

The cutting blade 101 and the forming member 102 are integrally provided in the driver body 100 constituting the penetrating mechanism 37. The driver body 100 and the pressure plate 92 are relatively movable in the up-down direction Z of the receiving seat 58. In this embodiment, a structure in which the receiving seat 58 is fixed so that it cannot move in the upward and downward directions Z, and the driver body 100 and the pressure plate 92 are moved in the upward and downward direction Z is adopted. However, it is not limited to this, and the receiving seat 58 may also be used. A structure that moves the driver body 100 and the presser plate 92 in the up-down direction Z. The cutting blade 101 and the forming member 102 are quilted. It is housed in the presser plate 92 and can move relatively in the up and down direction Z in the presser plate 92. Furthermore, in this embodiment, the forming member 102 is integrally provided to the driver body 100 (the penetrating mechanism 37), but the present invention is not limited to this. As long as the forming operation can be performed in synchronization with the penetration operation of the penetration mechanism 37, the forming member 102 may be provided separately from the driver body 100.

The driver body 100 has a shaft hole 100a extending in the left-right direction Y, and the above-mentioned link shaft 15 is penetrated and arranged in this shaft hole 100a. The link shaft 15 is inserted and arranged in a guide groove 17 extending in the vertical direction Z. The guide groove 17 is provided in the first guide groove portion 21 of the above-mentioned link 18 (see FIG. 9) and is bound. The side surface 16 (side wall) of the machine body 5. The link shaft 15 is guided along the guide groove 17. The actuator body 100 moves in the vertical direction Z.

The cutting blade 101 is an example of a cutting blade for cutting the connecting portion 3 a of the connecting needle 3, and an inclined blade portion 101 a is provided at the lower end. Each of the cutting blades 101 is attached to a pair of mounting portions 103 protrudingly provided on the back side (rear) of the driver body 100 with the inclined blade portions 101 a facing outward.

Each cutting blade 101 is designed to smoothly cut the connection portion 3a. Each blade portion 101a is inclined outward, and the inner side surface near the cutting edge is inserted into the hole portion 4 located inside the connection portion 3a. The cutting portion 101 is attached to the mounting portion. 103. The length of each blade portion 101a is longer than that of the connecting portion 3a. In addition, each cutting blade 101 cuts out the outside of the blade portion 101a and is provided with a notch portion 101b. As a result, when the cutting blade 101 moves relatively to the presser plate 92 in the up-down direction Z, the blade portion 101a does not touch A constituent member of the presser plate 92.

Each forming member 102 is provided at a position that becomes the inside of each cutting edge 101, and includes a portion extending downward from a wall surface of each mounting portion 103 The arm portion 102a and the projection portion 102b are formed to protrude from the front end (lower end) of the arm portion 102a toward the inside. The front end of the arm portion 102a is a free end, and the base end portion (fixed end) fixed to the mounting portion 103 can be elastically deformed in the left-right direction Y as a base point.

In order to bend the pins 2b, 2c of the non-metallic needle 2 placed on the receiving seat 58, the formation height of each arm portion 102a from the upper end of the protruding portion 102b to the base end portion is set at least as high as the pins 2b, The length (height) of 2c is the same or more. The length (depth) of each arm portion 102 a in the front-back direction X is the same as or longer than the length in the short-side direction of the non-metal needle 2.

In addition, in order to hold the pins 2b and 2c between the receiving seat 58 and the inner wall surface of each arm portion 102a, the width of the receiving seat 58 is formed with a width approximately the same as the inner width of the top 2a. A pair of arm portions The interval of 102a is formed in the same size as the width of the top 2a. The interval between the pair of protrusions 102 b is formed to be slightly narrower than the width of the receiving seat 58. According to this configuration, when the protruding portion 102b is lowered, the protruding portion 102b touches the receiving seat 58 and elastically deforms on the outside, and the pins 2b, 2c are pressed down on the receiving seat 58 on the side between the protruding portion 102b and the receiving seat 58. Bend and bend the non-metal needle 2 securely The shape can be stably performed. After bending, the pair of pins 2b and 2c are held by the outer surface of the receiving seat 58 and the inner surface of the pair of arm portions 102a, so that the molded state can be maintained.

The needle presser plate 92 is formed in a rectangular frame shape, and a pair of restriction protrusions 104 are provided on the outer side surface of the needle presser plate 92 to guide the movement of the needle presser plate 92 in the upward and downward direction Z and limit the amount of movement. The pair of restriction protrusions 104 are attached to the side surface 16 (side wall) of the binding machine body 5 and are inserted into a pair of restriction grooves provided adjacent to the guide groove 17. 29 (see Fig. 42A, etc.). By guiding the restricting protrusion 104 along the restricting groove 29, the presser plate 92 moves in the vertical direction Z. The restriction groove 29 is formed as a long hole extending in the vertical direction Z. Therefore, when the restricting protrusion 104 touches the upper end of the restricting groove 29, the presser plate 92 stops rising. This stop position becomes the highest point of the presser plate 92. When the restricting protrusion 104 touches the lower end of the restricting groove 29, the presser plate 92 stops descending. This stop position becomes the lowest point of the presser plate 92. Furthermore, since the restricting protrusion 104 is formed in an ellipse shape that is long in the up-down direction Z, the inclination of the forward-back direction X is suppressed, and it can smoothly move in the up-down direction Z without shaking.

A pair of first restricting portions 91 are provided on the inner side surface of the presser plate 92 to restrict the position of the front end of the non-metallic needle 2 in the vertical direction Z. Further below the first restricting portion 91, a pair of presser pin portions 105 are provided. The presser pin portions 105 prevent one of the formed non-metal needles 2 from spreading the pins 2b, 2c, and maintain the formed state. The pressing needle portion 105 guides the needle tip inward with a tapered surface 105a protruding inward, and suppresses the needle tip from being opened. The pair of presser pin portions 105 is formed so as to be capable of being inserted and held. One of the glyphs is formed by the length of the insertion interval of the pins 2b, 2c. In addition, the formation height of each of the press pin portions 105 is such that the upper end of the press pin portion 105 does not interfere with the front ends of the pins 2b, 2c of the formed non-metal needle 2 when the press pin plate 92 is lowered to the lowest point. Height formed. That is, the pressing needle portion 105 is configured to form the non-metal needle 2 while lowering the forming member 102. In the shape of the font, it is retracted to a position where it does not contact the bent pins 2b, 2c.

On the other hand, when the presser plate 92 is raised together with the forming member 102 after the forming is completed, the arm portion 102a still holds the pins 2b and 2c (one part), and the tip of the presser portion 105 can pick up and hold the pin 2b , 2c size alignment. Therefore, the opening of the pins 2b and 2c at the time of the transfer from the arm portion 102a to the pins 2b and 2c of the presser portion 105 is suppressed, and the transfer (pick-up) can be performed stably.

Further, a pair of elastic pieces 106 (engaging portions) that are in contact with the shoulder portion 103 a of the mounting portion 103 provided in the driver body 100 are provided at approximately the center of the up-down direction Z on the inner side surface of the presser plate 92. Each elastic piece 106 is formed by a cantilever beam extending in the downward direction, the front end becomes a free end, and the fixed end is used as a base point, and elastic deformation occurs in the left-right direction Y. A protrusion 106a is formed at the front end of each of the elastic pieces 106 so as to protrude toward the inside. According to this configuration, when the driver body 100 raises the presser plate 92, the lower end of the elastic piece 106 touches the shoulder portion 103 a and engages, and the presser plate 92 rises together with the driver body 100. When the presser plate 92 is raised to the highest point, the shoulder portion 103 a pushes the elastic piece 106 outward and passes over the elastic piece 106, thereby releasing the engagement with each other, and only the driver body 100 rises.

In addition, when the driver body 100 is lowered to the needle press plate 92 at the lowest point, the pair of elastic pieces 106 are pushed outward by the mounting portion 103 of the driver body 100, and beyond the pair of elastic pieces 106, only the driver body 100 decline.

<Example of operation of the cutting and shaping mechanism 35>

Next, an operation example of the cutting and forming mechanism 35 will be described with reference to the operation diagram of the cutting and forming mechanism 35 in FIGS. 40A and 40B and the operation diagram of the link 18 in FIGS. 42A to 42F. 40A and 40B are views of the cutting and forming mechanism 35 as viewed from the back side, and states of the operation process of the cutting and forming mechanism 35 are shown in states A to F. In FIGS. 40A and 40B, for ease of explanation, only the cutting blade 101, the forming member 102, the presser plate 92, and the link shaft 15 are illustrated. Figures A ~ F shown in Figure 42A ~ 42F indicate the cut The state (position) of the link shaft 15 in the state A to state F (F-1, F-2). A to C indicate the state during the pressing operation, and D to F indicate the state during the return operation. status. For details of the constituent members, refer to FIG. 39 together.

In the standby position (starting position) before the pressing operation of the operating handle 6, as shown in the state A (standby) in FIG. 40A, the front end of the connecting pin 3 is arranged on the receiving seat 58 in a flat state before cutting. Of non-metallic needles 2. The push rod 61 (see FIG. 19) is biased in the direction (front) of the receiving seat 58 by the push rod return spring 47. Therefore, as shown in FIG. 42A, the front end of the guide arm 65 of the pusher 61 is located further forward than the locking small convex portion 67 provided in the guide portion 66 of the stapler body 5. Thereby, the tip of the push rod 61 as the pressing surface 63 is in a state of protruding into the presser plate 92 (see FIG. 26). A non-metallic needle 2 (refer to FIG. 22) that has been cut and shaped is mounted between a pair of penetrating blades 36 (hereinafter, referred to as 36a and 36b in the case of distinguishing left and right).

When the operator depresses the operation handle 6, by this depressing operation, the link shaft 15 is lowered, and the driver body 100 and the link 18 are depressed. The link 18 is lowered so that the pressing protrusion 30 faces the rear pressing shaft 25. Then, as shown in FIG. 42B, the guide protrusion 23 is contacted by the upper edge portion of the first guide groove portion 21, and the lowering of the link 18 is stopped. At this time, the front end of the guide arm 65 of the push rod 61 crosses the inclined surface 67a of the small projection 67 for locking, and the push rod 61 moves backward, whereby the push rod 61 is disengaged from the needle pressing plate 92, and the needle pressing plate 92 can be lowered. . At this time, the first restricting portion 91 provided on the inner side surface of the presser plate 92 touches the connecting pin 3, but the first restricting portion 91 is capable of slightly elastically deforming both ends of the connecting pin 3 with one side. Since the protruding amount is formed, breakage and the like of both ends of the connecting needle 3 can be prevented.

In addition, by lowering the link shaft 15, the driver body 100 and the pressure needle Both sides of board 92 fell. By this, when the pressure needle plate 92 reaches the lowest point and the descent is stopped, only the driver body 100 connected to the link shaft 15 is lowered, as shown in the state B (cutting) in FIG. 40A, and the cutting edge 101 is cut. 101 a cuts the connecting portion 3 a of the connecting pin 3 (cutting operation), and separates a non-metallic pin 2 from the connecting pin 3. In addition, for reference, a plan view of the cut-out connecting pin 3 is recorded in the state B. Since the connecting portion 3a is cut from the inside to the outside by the outwardly inclined blade portion 101a, it is cut in a stable state. After this cutting, the actuator body 100 is further lowered, and then, following the cutting operation, the front ends (lower ends) of the arm portions 102a of the pair of forming members 102 reach the non-metallic needle 2, and the arm portion 102a brings the non-metallic needle 2 pins 2b , 2c is bent downward (start of forming operation).

On the other hand, since the link 18 is restricted from descending by the guide projection 23, the link 18 is moved backward by the lowering of the link shaft 15. Then, as shown in FIG. 42C, the rear extension portion 18b touches the restricting protrusion portion 24, and the link 18 stops moving backward. By further lowering the connecting rod shaft 15, the connecting rod 18 starts to rotate backward with the guide protrusion 23 as a fulcrum (counterclockwise rotation in FIG. 42C), and the guide guided by the third guide groove portion 28 is folded. The sliding member 122 of the bending mechanism 38 starts to retract (refer to FIG. 42D).

As shown in FIG. 42E, when the link shaft 15 is lowered to the lowest point and the sliding member 122 is finally retracted, as shown in the state C (forming) in FIG. 40A, the cutting of the non-metallic needle 2 is performed. The finished state driver body 100 reaches the lowest point. The pins 2 b and 2 c of the formed non-metallic needle 2 are held by the arm portion 102 a of the forming member 102.

Then, by releasing the pressing force of the operation handle 6, the operation handle 6 moves toward the returning position of the starting position by the biasing force of the handle return spring 45 (return Position), the link shaft 15 starts to rise. In conjunction with these actions, the link 18 rotates in the return direction with the guide protrusion 23 as a fulcrum (clockwise rotation in FIG. 42E), the sliding member 122 moves (forward) in the return direction, and the driver body 100 rises . The driver body 100 rises, and the shoulder portion 103 a of the mounting portion 103 touches the elastic piece 106 of the pressure plate 92, whereby the pressure plate 92 rises together with the driver body 100. During this raising process, in the state where the arms 102a are holding the pins 2b and 2c, the pins 2b and 2c are inserted between the pair of presser portions 105 of the presser plate 92, and the needle tips can be picked up (received and held). For example, the state D (pick-up pin) in FIG. 40A indicates a state where the needle tip is about to be picked up. Because the protruding point 102b of the forming member 102 closes the needle tips of the pins 2b and 2c slightly inward, the needle tip 105 can be easily picked up . However, since the tapered surface 105a of the pressing needle portion 105 guides the needle tip inward, as shown by the virtual line in the state D diagram, the needle tip can be reliably picked up even if the pin 2b 'is slightly opened.

Therefore, it is possible to smoothly transfer the stitches 2b, 2c from the forming member 102 to the pressure pin portion 105. In addition, only the pressure pin 105 is raised, the pins 2b, 2c can be held by the pressure pin 105, and the elastic deformation of the pins 2b, 2c can be suppressed. The load on the pins 2b, 2c can be reduced, and more stable molding can be performed. .

Then, as shown in the state E (the highest point of the presser plate 1) in FIG. 40B, when the presser plate 92 reaches the highest point, the presser plate 92 stops rising. As shown in state E, the pins 2b and 2c of the non-metallic needle 2 are detached from the arm portion 102a, but are held by the pair of presser portions 105. By the subsequent rise of the link shaft 15, the shoulder portion 103 a of the mounting portion 103 pushes the pair of elastic pieces 106 outward, thereby passing over the pair of elastic pieces 106 to release the engagement with each other. As a result, the driver body 100 is disengaged from the presser plate 92 because it is locked from the lower part of the presser plate 92 It is released, so only the driver body 100 is raised (refer to the state F-1 (the highest point of the pressure plate 2) in FIG. 40B).

In a state where the engagement between the driver body 100 and the presser plate 92 is released, the presser plate 92 can fall freely in the restriction groove 29. In this case, as shown in the state F-2 (the pressure plate is dropped) in FIG. 40B, the pins 2b, 2c are hooked to the front end of the pressure needle portion 105 to prevent the pressure needle portion 105 from being detached.

In the state where the sliding member 122 is completely returned, the above-mentioned link 18 stops rotating, but as shown in FIG. 42F, the guide arm 65 of the push rod 61 is engaged with the locking surface 67b of the small projection 67 for locking. Because it is in the locked state, the forward movement of the putter 61 is also restricted. By the subsequent rise of the link shaft 15, the link 18 and the driver body 100 rise, and the driver body 100 rises to the timing of receiving the formed non-metal needle 2 between a pair of penetrating blades 36a, 36b. The lower edge portion of the groove portion 27 pushes the guide arm 65 upward. Thereby, the guide arm 65 is disengaged from the small convex portion 67 for locking, the push rod 61 is advanced by the biasing force of the push rod return spring 47, and the non-metal needle 2 is fed to the pair of penetrating blades 36a by the pressing surface 63. 36b. Further, on the receiving seat 58, the connecting needle 3 in a flat state which is subsequently used is fed, and the cutting and forming mechanism 35 returns to the standby state (state A '(ejecting pin) in Fig. 40B). The link 18, the link shaft 15 and the like also return to the starting position (refer to FIG. 42A).

[About penetration mechanism 37]

As shown in FIG. 39, FIG. 43, and FIG. 44, the penetrating mechanism 37 described above forms a through hole p1 (see FIG. 3) in the paper P, and includes a pair of left and right penetrating blades 36a, 36b. The pins 2b, 2c of the non-metallic needle 2 are passed through the paper P; and the pressing portion 110 is pushed to restrain the top 2a of the non-metallic needle 2. The penetrating blades 36a, 36b and the pusher 110 are provided on the driver body 100, and The link shaft 15 moves in the vertical direction Z together with the driver body 100.

A pair of penetrating blades 36a, 36b are attached to the lower side of the driver body 100, and are mounted parallel to the left-right direction Y via a predetermined interval capable of accommodating and holding the non-metallic needle 2. A pair of penetrating blades 36a, 36b extend from the driver body 100 to the lower side. At the lower end, V-shaped blade portions 111 a and 111 b of the cutting paper P are provided. Each of the penetrating blades 36a and 36b is bent into a substantially crank-shaped (or inclined-segment-like) shape when viewed from the front or rear. The upper end (base end portion) and the lower portion 111a, 111b does not lie on a straight line in the up-down direction Z, but has a shape in which the blade portions 111a and 111b on the lower end side are offset inward from the upper end (base end portion).

More specifically, the distance between the pair of penetrating blades 36a and 36b is in a range of a predetermined length from the front end side of the provided blade portions 111a and 111b, which is approximately the inner width of the top 2a, that is, the inner width of the pair of stitches 2b and 2c. The first penetrating portions 112 a and 112 b which are the same or slightly narrower and first constitute the penetrating sheet P are formed. From the upper side to the base end side of the first penetration portion 112a, 112b, the outer width of the top 2a, that is, the width of the pair of pins 2b, 2c, is approximately equal to or slightly wider, and constitutes the second penetration portion 113a, 113b. In addition, the term "equivalent" referred to in this patent specification does not necessarily have to be the same size, as long as it is "approximately equal", and it includes the meaning of a slightly larger or smaller case such as a size in the scope of common sense. Slight dimensional errors are allowed.

It is bent into a substantially crank shape at a predetermined intermediate position which is a boundary between the first penetration portions 112a, 112b and the second penetration portions 113a, 113b, and an inclined step is formed in the first penetration portions 112a, 112b and the second penetration portions 113a, 113b. At this step, the distance between the pair of penetrating blades 36a and 36b is formed to gradually widen from the first penetrating portions 112a and 112b to the second penetrating portions 113a and 113b, and It becomes a hole expansion part 114a, 114b which expands the penetration hole p1 formed by the 1st penetration part 112a, 112b to the outer direction.

In addition, it can be held to form between a pair of second penetration portions 113a and 113b arranged to face each other. Z-shaped non-metal needle 2. In addition, the stepped portion of the boundary between the second penetrating portions 113a, 113b and the hole expansion portions 114a, 114b becomes the pin supporting portions 115a, 115b that support the pins 2b, 2c of the non-metallic needle 2 held by the second penetrating portions 113a, 113b. .

In each of the penetrating blades 36a and 36b, first and second bending members 120a and 120b (see Fig. 45) are formed so as to pass through the second penetrating portions 113a and 113b and the pin supporting portions 115a and 115b. The first and second bending members 120a and 120b are a pair of bending members serving as a bending mechanism 38 that bends the pins 2b and 2c penetrating the paper P inward. In addition, as long as the first and second bending members 120a and 120b (refer to FIG. 45) are accessible, they are not limited to the hole portions 116a and 116b, and the second penetration portions 113a and 113b and the pin support portions 115a and 115b may be used. Part of the cutout.

The pushing-down portion 110 is provided between the pair of penetrating blades 36a and 36b. The pusher 110 is configured to be movable in the vertical direction Z of the driver body 100 and is mounted on the driver body 100 in a state of being biased downward by the pusher spring 46.

In the binding machine 1 of this embodiment, as described above, when the penetrating mechanism 37 is lowered to a predetermined position, the bending mechanism 38 operates to start bending the stitches 2b and 2c. Therefore, since the stitches 2b, 2c are bent at a predetermined timing without being affected by the difference in the number of sheets (thickness) of the sheet P, the number of sheets of the sheet P is absorbed by the movement of the pressing portion 110 in the up and down direction Z. (Thickness) makes penetration The mechanism 37 can be lowered to a predetermined position.

The penetrating mechanism 37 includes a metal penetrating blade guide 117 (see FIG. 45) made of a metal, which guides penetrating blades 36 a and 36 b of the penetrating paper P in the lower portion of the binding machine body 5. As described above, the penetrating blades 36a and 36b are located at the blade portions of the penetrating blades 36a and 36b because the base end portion of the fixed side of the driver body 100 and the front-end blade portions 111a and 111b are not aligned with each other in the vertical direction Z. When 111a and 111b penetrate the paper P, the force of the penetrating blades 36a and 36b is shifted inward (the penetrating blades 36a and 36b are inclined inward). Furthermore, since the distance between the pair of hole expansion portions 114a and 114b gradually widens, when the hole expansion portions 114a and 114b push the penetration hole p1 while passing through, the force is also shifted inward by the penetration blades 36a and 36b ( Tilted inward).

A penetrating blade guide 117 is provided to prevent the penetrating blades 36a, 36b from shifting inwardly and to prevent the penetrating blades from shifting leftward and rightward. When penetrating, the penetrating blades 36a and 36b move downward. The side of the zigzag penetrating blade guide 117 is lowered to prevent the penetrating blades 36a and 36b from shifting inward (deformation), and the penetrating operation of the paper P through the penetrating blades 36a and 36b can be performed smoothly.

As shown in FIG. 41, the penetrating blade guide 117 includes a first guide portion 117 a and a second guide portion 117 b having a lower height than the first guide portion 117 a. Moreover, the upper edge corner portion in front of the first guide portion 117a (on the side of the second guide portion 107b) is chamfered into a tapered or curved shape that descends forward to provide a chamfered portion 117c. In addition, in the present embodiment, it is formed through an interval substantially the same as the interval between the first penetration portions 112a and 112b. The front side of the plate member is cut off to form a step. The uncut side is used as the first guide portion 117a, and the lower side is used as the second guide portion 117b. Thereby, one element is integrally formed. The first and second guide portions 117a and 117b. According to this configuration, the number of components of the binding machine 1 can be reduced, the configuration can be simplified, the size can be reduced, and the first and second guide portions 117a and 117b can be operated integrally.

In addition, the configuration of the penetrating blade guide 117 is not limited to that shown in the first embodiment, and the first guide portion 117a and the second guide portion 117b are constituted by one element. 2guide parts 117a, 117b. In addition, it is also possible to adopt a structure in which the first and second guide portions 117a and 117b formed separately are operated synchronously. As long as the penetration blades 36a and 36b are formed, the inner side surface near the blade edge can always be guided in accordance with the penetration amount. The continuous surface can also be operated independently.

The first guide portion 117a is designed to prevent the paper P from being bent during the penetrating operation. The height of the top of the first guide portion 117a is made to be approximately the same as the paper holder 7 on which the paper P is placed (or the same plane) or to the paper holder 7 Slightly lower. This makes it possible to reduce the load when the pair of penetrating blades 36a, 36b penetrates the paper P, and smoothly perform the penetrating operation, so that the width of the penetrating hole p1 does not exceed the need. Further, by adopting such a formation height, when the penetrating blades 36a, 36b penetrate the paper P and the inner side surface near the cutting edge protrudes from the paper P, the inner surface near the cutting edge can be guided by the first guide portion 117a immediately, It is possible to further improve the effect of preventing the shift of the penetrating blades 36a, 36b inwardly and laterally.

On the other hand, when the second guide portion 117b is a pair of pins 2b and 2c of the non-metallic needle 2 and penetrates the paper P together with the penetrating blades 36a and 36b, the height of the front end of the penetrating blades 36a and 36b can be guided and bent. The height at which the mechanism 38 can perform the bending operation using the space between the second guide portion 117b and the binding machine body 5. It is preferable to use a lower height than the positions of the front ends of the pins 2b and 2c when the penetrating blades 36a and 36b are lowered to the lowest end, or to prevent the bending mechanism 38 from being blocked. 1. The height of the hole portions 116a, 116 into and out of the second bending members 120a, 120b. However, in the specifications where the bending of the pins 2b, 2c starts before the penetrating blades 36a, 36b reach the lowermost end, the second guide portion 117b may be formed slightly more than the front ends of the pins 2b, 2c before the bending. high.

The penetrating blade guide 117 is provided on a sliding member 122 described later in the bending mechanism 38. The first guide portion 117a and the second guide portion 117b are switched in accordance with the penetrating length of the penetrating blades 36a and 36b of the paper P in an interlocking manner with the reciprocating action of the sliding member 122, and are arranged at the penetrating blades 36a, 36b. When the through-holes p1 are formed through the penetrating blades 36a and 36b (when the penetrating length is relatively short), the first guide portion 117a is disposed between the pair of penetrating blades 36a and 36b and guides the penetrating blades 36a and 36b. Tips (at least the blade portions 111a and 111b are more preferably connected to the first penetration portions 112a and 112b).

On the other hand, with the pair of penetrating blades 36a, 36b falling further, the paper P is penetrated deeply (the penetrating length becomes relatively long), and the pair of pins 2b, 2c of the non-metal needle 2 penetrates the paper P. When the pins 2b and 2c of the penetrating paper P are bent by the bending mechanism 38, the first guide portion 117a retracts from between the pair of penetrating blades 36a and 36b, and the second guide portion 117a is lower than the first guide portion 117a. The guide part 117b exists. With this, the second guide portion 117b guides the front ends of the penetrating blades 36a and 36b, while suppressing the jitter or inward deformation of the penetrating blade 6b in the left-right direction Y, while preventing the borrowing of the first and second bending members. The bending action of the pins 2b and 2c of 120a and 120b. The penetrating blades 36a and 36b are formed by the penetration of the paper P and the bending of the non-metallic needle 2. According to the total amount of penetration of the penetrating blades 36a and 36b, the continuous inner side surface near the edge of the blade can be guided. Surface, and the penetrating blades 36a, 36b can be reliably moved relative to each other between the first guide portion 117a and the second guide portion 117b.

In this embodiment, the upper side of the second guide portion 117b is horizontal at the rear side, but the front side is gradually lowered in height, and inclined forward. That is, when the pair of penetrating blades 36a, 36b descends with the retreat of the slide member 122, the front side is relatively inclined along a path passing through the side surface of the second guide portion 117b along the front end (near the blade edge). With this inclination, when the pair of penetrating blades 36a, 36b is lowered to the lowermost end, the front side of the pair of penetrating blades 36a, 36b can be surely guided by both side wall surfaces of the second guide portion 117b, and the hole can be suppressed. Portions 116a, 116b are plugged. Therefore, the first and second bending members 120a and 120b can be smoothly moved in and out of the hole portions 116a and 116b.

<Example of operation of penetration mechanism 37>

Next, referring to the explanatory diagrams of the binding machine body in Figs. 43 and 44, the operation diagrams of the penetrating mechanism 37 in Figs. 40A and 40B, and the operation diagrams of the penetrating blade guide 117 in Fig. 41, the penetration will be described. An example of the operation of the mechanism 37. In the state of the standby position before the penetration operation (refer to the state A in Fig. 40A), as shown in Figs. 43 (b) and (e), the cutting and forming mechanism 35 is held between the pair of penetrating blades 36a and 36b. Fed Z-shaped non-metal needle 2. At this time, the top 2a is pressed by the top pressing portion 110, and the pins 2b, 2c are supported by the pin support portions 115a, 115b.

When the link shaft 15 is lowered by the depression operation of the operation handle 6, the driver body 100 provided with the penetrating mechanism 37 is lowered (see FIG. 41 (a)). Then, when the penetrating blades 36a and 36b reach the paper P placed on the paper holder 7, the penetrating portions 111a and 111b form the penetrating hole p1 in the paper P (refer to the dotted line portion of the state B in FIG. 40A). The 1 penetrating portions 112a and 112b penetrate the penetrating hole p1. At this time, the first guide portion 117a of the penetrating blade guide 117 is disposed in the penetrating portion. Between the penetrating blades 36a and 36b, it is possible to prevent the first penetrating portions 112a and 112b from tilting inward in a smooth direction, and to allow smooth penetration.

When the penetrating mechanism 37 is further lowered, the hole expansion portions 114a and 114b penetrate the paper P while expanding the penetrating hole p1 while facing the outer direction. When the penetrating mechanism 37 is lowered further, the second penetrating portions 113a and 113b penetrate the penetrating hole p1, and the pair of pins 2b and 2c of the non-metallic needle 2 held inside the second penetrating portions 113a and 113b penetrate the penetrating hole p1 ( (See Figure 41 (b)).

When the top 2a reaches the paper P (see state C in FIG. 40A), the top 2a is pressed to the paper P by the top pressing part 110, so that the top 2a and the paper P can be brought into close contact. In addition, even when the number of sheets of paper P is large, as shown in the diagrams of FIG. 44, in the state where the top pressing part 110 pushes the top 2 a to the sheet P and stops, only the top spring 46 is compressed while being compressed. The driver body 100 is lowered. Therefore, the penetration blades 36a, 36b can be lowered to a predetermined position without being affected by the number of sheets of the paper P. Therefore, the subsequent bending operation of the stitches 2b and 2c by the subsequent bending mechanism 38 can be smoothly performed at a predetermined timing.

At this timing of the bending operation, as shown in FIG. 41 (c), the penetrating blade guide 117 and the sliding member 122 are moved backward and backward, and a second guide portion 117b is arranged between the penetrating blades 36a and 36b. . Therefore, the bending operation of the stitches 2b and 2c by the bending mechanism 38 can be performed smoothly. In addition, the forces acting on the penetrating blades 36a and 36b are uniform on the second penetrating portions 113a and 113b, and it is difficult for the forces inclined to the inside to act on the penetrating blades 36a and 36b. Therefore, at the timing when the second penetrating portions 113a and 113b penetrate the penetrating hole p1, even if the penetrating blades 36a and 36b are not guided, the deformation can be suppressed. However, in this embodiment, at the timing when the paper P is penetrated by the second penetrating portions 113a and 113b, the penetrating blade is guided by the second guiding portion 117b. The front ends of 36a, 36b. Therefore, the inward deformation of the penetrating blades 36a and 36b is prevented, and the pair of first and second bending members 120a and 120b are prevented from entering and exiting the hole portions 116a and 116b of the penetrating blades 36a and 36b during the bending operation. The penetrating blades 36a and 36b can perform the penetrating operation and subsequent bending operations more smoothly by shaking in the left-right direction Y and the like.

After binding the paper P, as shown in FIG. 41 (d), the movement of the slide member 122 and the penetrating blade guide 117 is stopped. Then, when the pressing of the operation handle 6 is released, the driver body 100 rises together with the link shaft 15, the penetrating blades 36 a and 36 b leave the penetrating hole p1, and the penetrating mechanism 37 returns to the standby position. As a result, the slide member 122 also performs a returning operation (forward) to the original position, and the first guide portion 117a also moves between the penetrating blades 36a and 36b. In this embodiment, the chamfered portion 117c is provided in front of the first guide portion 117a, and when the first guide portion 117a is returned, the chamfered portion 117c is lifted up to overlap the lower side of the paper P The stitches 2b and 2c move at the same time. Therefore, the returning operation of the first guide portion 117a below the pins 2b and 2c can be performed more smoothly, and the roll-up of the pins 2b and 2c can be suppressed.

Next, a modification of the penetrating blade guide 117 will be described with reference to FIGS. 41A and 41B. 41A and 41B are operation diagrams of a modification example of the penetrating blade guide 117. The penetrating blade guide 117 according to the modification shown in Figs. 41A and 41B is different from the shape of the second guide portion 117b. The basic structure is the same as that of the penetrating blade guide 117 shown in Fig. 41 and includes The first guide portion 117a and the second guide portion 117b having a lower height than the first guide portion 117a.

In the modification shown in FIG. 41A, the upper portion of the second guide portion 117b The edge 117d has a shape inclined linearly from the front end of the first guide portion 117a to the front at two different inclination angles, and the side view has a V shape in which the inner angle is an obtuse angle.

In the modification shown in FIG. 41B, the upper edge 117d of the second guide portion 117b is inclined in a curve from the front end of the first guide portion 117a to the front, and the front side is continuously inclined in a straight line with this curve. shape. In addition, the entire upper edge 117d of the second guide portion 117b may be formed in a curvedly inclined shape. In this modification, the chamfered portion 117c is provided in front of the first guide portion 117a.

The penetrating blade guide 117 of this modification is also shown in the operation diagrams of (a) to (d) in Figs. 41A and 41B, and can be operated in the same manner as the embodiment in Fig. 41, and can be obtained and implemented. Examples have the same effect and effect. Furthermore, by inclining the upper edge 117d of the second guide portion 117b linearly or curvedly, the second guide portion 117b can be inclined along the descending path of the blade portions 111a and 111b penetrating the blades 36a and 36b. shape. Therefore, the penetrating blade guide 117 of each modification can more smoothly guide the penetrating blades 36a and 36b without interfering with the bending operation of the bending mechanism 38, and can suppress the deformation thereof.

[About the bending mechanism 38]

As shown in FIG. 45 to FIG. 48, the above-mentioned bending mechanism 38 includes a first bending member 120a, which is one of the non-metal pins 2 penetrating through the paper P (the right side pins in this embodiment). ) Bending; the second bending member 120b is used to bend the other pin (the pin on the left side in this embodiment); the adhesion member 121 is used to paste the pin 2b on one side and the pin 2c on the other; The sliding member 122 as the driving member is in the determined sequence The first and second bending members 120a and 120b and the adherent member 121 are driven; and a pair of guide surfaces 123a and 123b (refer to Figs. 47 and 50A) are provided on the binding machine body 5 and directed to The bending direction guides the inclined surfaces of the first and second bending members 120a and 120b.

The first and second bending members 120a and 120b include: bending protrusions 124a and 124b which bend inwardly the pins 2b and 2c formed by protruding upwards; and first and second inclined surfaces 125a and 125b which are connected to One of the binding machine bodies 5 is engaged with the guide surfaces 123a and 123b; and the first and second operation section portions 126a and 126b are engaged with the sliding member 122. The first bending member 120a and the second bending member 120b control the movement in the up-down direction Z and the left-right direction Y by the forward and backward movement of the sliding member 122 in the forward and backward directions X.

Along with this movement in the up-down direction Z and the left-right direction Y, the first and second inclined surfaces 125a and 125b are guided along the pair of guide surfaces 123a and 123b, whereby the first and second bending members 120a, 120b moves while moving toward and away from each other in an oblique direction with an interval (nearly distant). Thereby, the 1st and 2nd bending protrusions 124a and 124b pass in and out of the hole parts 116a and 116b of the penetrating blades 36a and 36b of one of the penetrating sheets P.

The first bending member 120a and the second bending member 120b are integrally connected by a U-shaped connecting spring 127 in a plan view, and constitute an Ω-shaped bending unit 128 in a plan view. In this embodiment, the first and second bending members 120a, 120b and the connecting spring 127 are integrally formed with resin to form a bending unit 128, and the bending unit 128 is attached to the binding state while the connecting spring 127 is compressed. The inner surface of the machine body 5. Therefore, it is excellent in shape stability or flexibility, and can accommodate the bending unit 128 of the binding machine main body 5. The second bending members 120a and 120b move in the vertical, horizontal, and leftward directions.

The connection spring 127 is biased in a direction to move the first and second bending members 120a and 120b outward, that is, in a direction (returning direction) in which the first and second bending members 120a and 120b are pushed downward. Therefore, when the first and second bending members 120a and 120b are pushed down and returned to the starting position by the returning action of the sliding member 122, the restoring force of the connecting spring 127 assists the returning action and suppresses jamming, etc. , And can perform the return movement smoothly, and can improve the operability during the return movement. In addition, the connection spring 127 may be configured to be opposite to the above, and biased in a direction to move the first and second bending members 120a and 120b inward, that is, a direction in which the first and second bending members 120a and 120b are pushed upward. , Can improve the operability during bending action.

When the bending unit 128 is attached to the binding machine body 5, as shown in FIG. 47, the mounting protrusion 129 protruding from the connection spring 127 is engaged with the hole portion 130 provided in front of the binding machine body 5, and The mounting protrusions 131a and 131b (see FIG. 45) protruding from the first and second bending members 120a and 120b, respectively, are formed in a length that is recessed corresponding to the inclination of the guide surfaces 123a and 123b toward the binding machine body 5. The holes 132a and 132b are engaged. Thereby, the bending unit 128 is prevented from accidentally falling out of the binding machine body 5 and the like, and the first and second bending members 120a and 120b can be moved upward, downward, leftward, and rightward (oblique directions).

The coupling spring 127 is not limited to a U-shape in a plan view. As long as the first bending member 120a and the second bending member 120b can be biased in a downward pushing direction (or pushing upward direction), a connecting spring 127 such as a V-shape, a W-shape, or an I-shape in a plan view may be used.

One pair of guide surfaces 123a, 123b for guiding one of the first and second bending members 120a, 120b is shown in FIG. 50A, with the lower end located at the outermost side in the left-right direction Y, and gradually inclined inward toward the upper end. Surface. That is, a pair of guide surfaces 123a, 123b are formed in a front view as Glyph. In addition, the guide surfaces 123a and 123b are not necessarily limited to continuous surfaces, and may be formed by a plurality of separated surfaces.

The inclination angle (inclination angle with respect to the horizontal direction) of each guide surface 123a, 123b is set to about 45 ° in the present embodiment, but it is not limited to this. The first and second bending members 120a, 120b or The movable range, operation timing, and the like of the sliding member 122 are appropriately adjusted.

As shown in this embodiment, by setting the inclination angle to about 45 °, in the narrow space in the binding machine body 5, the first and second bending members can be made as short as possible as the moving distance of the sliding member 122 is as short as possible. 120a, 120b are pushed up efficiently. In addition, the penetrating blades 36a and 36b may decrease the penetrating hole p1 of the paper P while expanding downward, and the lower edge of the penetrating hole p1 may be warped downward and protrude downward. In this case, by setting the guide surface to about 45 °, interference between the dangling edge and the first and second bending protrusions 124a and 124b can be avoided, so that the first and second bending members 120a and 120b can be smoothly smoothed. Move up and down diagonally. Therefore, the operability of the first and second bending members 120a and 120b can be improved, and the operability or downsizing of the binding machine 1 can also be improved.

The sticking member 121 (refer to FIG. 45) is one end side (front end side) via a support shaft 133 (refer to FIG. 48, FIG. 51, etc.) extending in the left-right direction Y, and is supported by the binding machine main body in 5 axes so as to be able to move up and down. To turn. On the other end (rear end) of the adhesion member 121, a pressing portion 134 is provided to press one of the pins 2b of the non-metallic needle 2 and the other of the pins 2c from the lower side to adhere to each other. By attaching components 121 rotates up and down with the support shaft 133 as a fulcrum, and the pressing portion 134 moves in the vertical direction Z.

The sliding member 122 (refer to FIG. 45) slides the binding machine body 5 in the front-rear direction X to push the first and second bending members 120 a and 120 b and the adhesion member 121 upward or toward each other as appropriate. Push down to move it up and down. As shown in FIG. 11, the sliding member 122 is attached to the binding machine body 5 in a state capable of sliding movement in the front-rear direction X. The sliding member 122 is always biased forward (returning direction) by the sliding member return spring 48. The above-mentioned shaft 26 (sliding member driving shaft, see Fig. 9) is provided behind the sliding member 122, and the third guide groove portion 28 (see Figs. 42A and 48) is inserted into the above-mentioned link 18 ) To connect the sliding member 122 and the link 18. Therefore, the slide member 122 and the operation handle 6 are connected via the link 18, and the slide member 122 and the operation handle 6 can be operated in conjunction with each other.

The link 18 converts the reciprocating motion of the operating handle 6 in the up-down direction Z into the reciprocating motion of the sliding member 122 in the forward-backward direction X. The slide member 122 basically reciprocates in the forward and backward direction X in conjunction with the rotation of the link 18 (see FIG. 42E and the like). Furthermore, the third guide groove portion 28 is formed to be long in the vertical direction Z, and only the link 18 and the operation handle 6 are allowed to move in the vertical direction Z under the engagement of the holding shaft 26 and the third guide groove portion 28.

That is, the operation handle 6 and the sliding member 122 are basically configured to operate in conjunction with each other via the link 18, but only a predetermined operation of the other one is allowed, and the connected state is maintained without being separated from each other.

As shown in FIG. 45 (c), the sliding member 122 is mounted on the penetrating blade guide 117 described above, and can be integrated forward and backward with the sliding member 122. The direction X is reciprocated. When the sliding member 122 is retracted and the first and second bending members 120a and 120b come in and out of the pair of hole portions 116a and 116b of the penetrating blades 36a and 36b, the penetrating blade guide 117 also moves backward together with the sliding member 122. The first guide portion 117a is retracted from between the penetration blades 36a and 36b, and a second guide portion 117b is disposed. Therefore, interference between the penetrating blade guide 117 and the first and second bending members 120 a and 120 b during the bending operation can be prevented.

The sliding member 122 is provided on both sides of the left-right direction Y, and the first and second side walls 135a and 135b that control the movement of the first and second bending members 120a and 120b in the up-down direction Z and the left-right direction Y are provided. The first and second operating step portions 126a and 126b of the first and second bending members 120a and 120b are engaged with the first and second side walls 135a and 135b, respectively.

As shown in FIG. 46, the first and second side walls 135a and 135b are sequentially from the rear (upper side in FIG. 46) to the front (lower side in FIG. 46). The first and second spare parts 136a, 136b, the first and second bending members 120a, 120b are not pushed up and held in the standby position (starting position); the first and second action portions 137a, 137b are the first and second folds The bending members 120a and 120b are pushed upward and guided toward the inside; and the first and second holding portions 138a and 138b are not to push the first and second bending members 120a and 120b upward by more than a predetermined amount, and The state of pushing in the existing direction remains.

The first and second spare portions 136a and 136b are formed at a height that does not push the first and second bending members 120a and 120b upward. The first and second operation sections 137a and 137b are formed by inclined surfaces that gradually increase in height as shown in Figs. 45, 50A, and 50B. Furthermore, as shown in FIG. 46, the first and second operation sections 137a and 137b are conventionally located inwardly on the front. The method is formed so that the interval between each other gradually narrows forward. The first and second holding portions 138 a and 138 b are continuous with the first and second operation portions 137 a and 137 b and are formed horizontally along the extending direction of the sliding member 122.

In this embodiment, first, the first bending member 120a is operated, and the right-side pin 2b is bent. Next, with the intervention of a predetermined phase difference, the second bending member 120b is operated to bend the other stitch 2c on the left side. In order to achieve this, the start position of the first operation portion 137a is provided on the rear side in the front-rear direction X than the position of the second operation portion 137b. According to this configuration, when the sliding member 122 is retracted, first, the first movement portion 137a pushes the first bending member 120a upward through the first movement step portion 126a and moves inward (with the first bending protrusion 124a from one of the holes). Direction in which the portion 116a protrudes). Then, the second operating portion 137b pushes the second bending member 120b upward through the second operating step portion 126b, and guides the second bending member 120b inward (direction in which the second bending protrusion 124b protrudes from the other hole portion 116b).

On the other hand, as shown in FIGS. 45 and 48, an operation shaft 139 extending in the left-right direction Y is provided at the front end of the sliding member 122, and the operation shaft 139 and a cam groove provided on the wall surface of the adhesion member 121 are provided. 140 snaps. The cam groove 140 and the operating shaft 139 are an example of a driving mechanism of the adhesion member 121, and converts the movement of the sliding member 122 in the forward and backward direction X into a rotation operation of the adhesion member 121 in the upward and downward directions Z.

The cam groove 140 includes: a spare groove portion 141, which moves the sliding member 122 in the forward and backward direction X, and does not rotate the phase adhesion member 121 and is maintained in a standby position (starting position); and the rotation groove portion 142 is used to make the phase The adhesive member 121 rotates; and the holding groove portion 143 maintains the adhesive structure in a predetermined rotating state. Piece 121.

The spare groove portion 141 is inclined in the extending direction of the opposing adhesive member 121 as shown in each figure of FIG. 51, and the adhesive member 121 is located at the standby position, and the pressing portion 134 is at the lowest point and becomes horizontal. The groove is made up. The rotation groove portion 142 is a groove formed in a shape inclined in a direction symmetrical to the spare groove portion 141. The holding groove portion 143 is a groove having a shape along the extending direction of the adhesive member 121.

As described above, by constituting the cam groove 140 and the operation shaft 139, the sliding member 122 moves backward, and when the pins 2b and 2c are bent by the first and second bending members 120a and 120b, the operation shaft 139 With the backup groove portion 141, the adhesion member 121 does not rotate, and becomes a standby state. At the timing when the bending of the pin 2c by the first and second bending members 120a and 120b is completed, the operation shaft 139 rotates the groove member 142, and the adhesion member 121 rotates, and the pressing portion 134 rises and presses. Pins 2b, 2c are stuck together. Then, the operation shaft 139 passes through the holding groove portion 143, the rotation of the adhesion member 121 stops, and the pressing portion 134 is maintained in a raised state.

<Example of Operation of Bending Mechanism 38>

Next, an operation example of the bending mechanism 38 will be described with reference to the operation diagrams of the members of the bending mechanism, such as FIG. 49 to FIG. 51. In the standby position (starting position) before the pressing operation of the operating handle 6 in Fig. 51 (a), the first and second bending members 120a and 120b are located at the lowest point (Fig. 50A). The operating shaft 139 of the sliding member 122 is located at the spare groove portion 141 of the adhesion member 121, and the pressing portion 134 is located at the lowest point (refer to FIG. 49 (a) and the like).

By pushing down the operation handle 6, the penetrating mechanism 37 moves At the timing when the first penetrating portions 112a, 112b of the penetrating blades 36a, 36b penetrate the paper P, the link 18 starts to rotate (see FIGS. 42D and 42E). When the shaft 26 is guided by the third guide groove portion 28, the sliding member 122 starts to move backward (retreat), and the bending mechanism 38 operates. First, the upper end of the first operation section 137a pushes the first operation section section 126a upward, whereby the first bending member 120a guided by one guide surface 123a rises diagonally. Thereby, the 1st bending protrusion 124a protrudes from the one hole part 116a to the inside of a pair of penetration blades 36a, 36b, and bends the one stitch 2b. Next, under the intervention of a predetermined phase difference, the upper end of the second action portion 137b pushes the second action segment portion 126b upward, whereby the second bending member 120b guided by the other guide surface 123b rises diagonally. . Thereby, the 2nd bending protrusion 124b protrudes from the other hole part 116b toward the inside of a pair of penetration blades 36a, 36b, and bends the other stitch 2c (refer above, FIG. 50B).

In addition, it may be configured such that the bending of the second bending member 120b to the other pin 2c is started in a state in which one of the pins 2b is completely bent, but in this embodiment, the first bending The timing (phase difference) in which the member 120a slightly bends one of the pins 2b inwardly starts the bending of the other pin 2c by the second bending member 120b. In this case, one pin 2b and the other pin 2c can be bent without interference, and the moving distance (stroke) of the sliding member 122 required for the bending of the pair of pins 2b and 2c can be made shorter. .

Moreover, the first and second bending members 120a and 120b are raised in the oblique direction by the action of the sliding member 122 and the guide surfaces 123a and 123b. Since the pins 2b and 2c are bent from a direction substantially orthogonal to the pins 2b and 2c, the escape of the pins 2b and 2c to the front-back direction X can be suppressed without applying an escape prevention measure. avoid. Therefore, the pins 2b and 2c can be smoothly bent, and the bending of the creases of the pins 2b and 2c can be suppressed, and the appearance or binding function can be improved.

In addition, when the stitches 2b and 2c are bent, the slide member 122 is retracted, and the first guide portion 117a of the penetrating blade guide 117 is retracted backward from between the pair of penetrating blades 36a and 36b to arrange the second guide. 117b (refer to FIG. 41 (c), FIG. 49 (b)). Therefore, the bending operation can be performed using the space between the stapler body 5 and the second guide 117b, and the first and second bending members 120a and 120b can be made without interference with the penetrating blade guide 117. Passes through the holes 116a, 116b. In addition, since the operating shaft 139 is located in the spare groove portion 141 between the operations of the first and second bending members 120a and 120b, the adhesion member 121 does not operate and is kept in a standby state.

Further, in this embodiment, it is adopted that the end side (front) of the first action portion 137b of the first bending member 120a is formed to be slightly lower, and at the time point when the bending of one of the pins 2b ends, such as from the 50C From the state shown in FIG. 50D to FIG. 50D, the first bending member 120a is lowered. According to this configuration, it is possible to further suppress interference between the first bending member 120a and the other pin 2c. In particular, it is effective when a long non-metallic needle is used with the pins 2b and 2c or when the paper P is thin and the pins 2b and 2c protruding from the paper P become long. Therefore, a binding machine 1 that can smoothly bend the pins 2b and 2c without being affected by the type of the non-metallic needle 2 used, the thickness of the paper P, and the like can be produced.

When the bending of the pair of stitches 2b and 2c is completed, the first and second operating section portions 126a and 126b of the first and second bending members 120a and 120b are positioned on the first and second holding portions 138a and 138b, thereby, The first and second bending members 120a and 120b stop rising. At this timing, the operation shaft 139 passes the rotation groove 142, and the phase The sticking member 121 rotates with the support shaft 133 as a fulcrum, and the pressing portion 134 rises, and pushes and sticks one pin 2b and the other pin 2c (see Fig. 49 (c), 50C, and 51) ( c)). At this time, since the second guide portion 117b of the penetrating blade guide 117 is located between the pair of penetrating blades 36a and 36b, the operation of the adhesion member 121 is not affected by the penetrating blade guide 117. When the adhesion of the pins 2b and 2c is completed, the operation shaft 139 passes through the holding groove portion 143, thereby stopping the rotation of the adhesion member 121 (Fig. 51 (c)). Then, the sliding member 122 also stops retreating (Fig. 49 (c)).

Next, by releasing the pressing operation of the operation handle 6, the operation handle 6 is pushed upward by the restoring force of the handle return spring 45, and the link 18 is rotated in the return direction and guided by the third guide groove portion 28. Thereby, the sliding member 122 moves to a return direction (front). In this way, the sliding member 122 can be forcibly returned by the link 18, but in this embodiment, a sliding member return spring 48 is further provided. The biasing force of the sliding member return spring 48 assists the movement of the sliding member 122 in the returning direction, so that the returning movement can be smoother.

Along with the return operation of the sliding member 122, the operating shaft 139 returns to the standby groove portion 141 by turning the groove portion 142, whereby the pressing portion 134 is lowered and returned to the standby position. In addition, the first and second bending members 120a and 120b are pushed by the sliding member 122 with the outer wall surfaces of the first and second action portions 137a and 137b facing outward, and the first and second bending members are moved. 120a and 120b are forcibly moved in a direction where they are separated from each other in the downward pushing direction and the left-right direction Y. In addition, in combination with the biasing force of the connecting spring 127, the first and second bending members 120a and 120b are smoothly pushed down and separated to return to the starting position. In this way, each of the bending mechanisms 38 can be linked with the return operation of the operation handle 6 by using the link 18. The part returns to the starting position.

In addition, by using the link 18 described above, the bending mechanism 38 can be operated in the entire area at a predetermined timing in relation to the penetrating mechanism 37 and the like that are directly driven by the operation handle 6, and the returning operation can also be interlocked. When there is no such interlocking relationship in the entire area, the returning of the sliding member 122 and the returning mechanism 37 and the like are performed independently. Therefore, for example, even if the sliding member 122 does not return due to a paper jam, a malfunction of the sliding member return spring 48, or the like, only the penetrating mechanism 37 and the like return individually. Therefore, the operator may continue the binding operation without noticing the defect of the bending mechanism 38, which may affect the durability of the constituent members or the operability of the binding machine 1.

In contrast, in this embodiment, because the actions of the various mechanisms and the return movement are linked by the link 18, one of the operation handle 6, the cutting forming mechanism 35, the penetrating mechanism 37, and the bending mechanism 38 malfunctions or returns. In an unfavorable situation, the operation or return operation of other mechanisms or the operation handle 6 is also stopped. Therefore, the operator can easily grasp that a malfunction occurs in one of the mechanisms when the operation handle 6 is not completely returned to the starting position, etc., and can quickly handle it. In addition, it is possible to prevent the operation from being continued due to failure to be noticed, and to prevent jamming of the constituent members, etc., thereby improving the durability of the binding machine 1.

Next, a modification of the bending mechanism will be described with reference to FIG. 52. In this embodiment, the first and second bending members 120a, 120b are biased in the returning direction (downward pushing direction) by the elastic force of the connecting spring 127 that connects the first and second bending members 120a, 120b. In contrast, in the modified examples of FIGS. 52 (a) to (c), the first and second bending members 120a and 120b respectively formed by the coil springs are biased in a pushing-up direction or a pushing-down direction.

In the modification shown in FIG. 52 (a), the first torsion coil spring 146 is provided between the protrusion 145 provided on the first bending member 120a and the protrusion 145 provided on the side surface of the binding machine body 5, and the first The bending member 120a is biased in a pushing-up direction. Further, the second bending member 120b is biased in the upward direction by a compression coil spring 147 disposed between the lower end of the second bending member 120b and the bottom surface of the binding machine body 5. In addition, the first bending member 120a may be biased by the compression coil spring 147, and the second bending member 120b may be biased by the torsion coil spring 146, and the first bending member 120b may also be biased by the torsion coil spring 146 or the compression coil spring 147. Both the second bending members 120a and 120b are biased.

In the modification shown in FIG. 52 (b), the torsion coil spring 149 provided between the protrusion 145 provided on the first bending member 120a and the protrusion 145 provided on the top surface of the binding machine body 5 The 1 bending member 120a is biased in the return direction. Further, the second bending member 120b is returned by the tension coil spring 150 disposed between the spring mounting portion 148 provided in the second bending member 120b and the spring mounting portion 148 provided in the binding machine body 5. Bit direction bias. In addition, the first bending member 120a may be biased by the tensile coil spring 150, and the second bending member 120b may be biased by the torsion coil spring 149, and the pair of 150 Both the first and second bending members 120a and 120b are biased.

In the modification shown in FIG. 52 (c), a compression coil spring 151 is disposed between a spring mounting portion 148 provided on the first bending member 120a and a spring mounting portion 148 provided on the second bending member 120b. The first and second bending members 120a and 120b are biased in the returning direction. In addition, instead of the compression coil spring 151, a tension coil spring 150 may be arranged, and the first and second bending members 120a, 120b is biased in a push-up direction.

As shown in this embodiment and each modification of Figs. 52 (b) and (c), by biasing the first and second bending members 120a and 120b in the returning direction, the first and second bending members can be increased. Operability when the bending members 120a and 120b are pushed down. Further, as shown in the modification of FIG. 52 (a), by biasing the first and second bending members 120a and 120b in the upward direction, the first and second bending members 120a and 120b can be increased. Operability when pushing up.

The means for biasing the first and second bending members 120a and 120b is not limited to the embodiment or the modification, and other springs such as a plate spring and a volute spring may be used. It is also possible to use a biasing means other than a spring. In addition, since the up and down movements of the first and second bending members 120a and 120b can be sufficiently controlled by the operating portion of the sliding member 122, such a biasing means may not necessarily be provided.

Alternatively, instead of gradually narrowing the interval between the first and second operating portions 137a and 137b of the sliding member 122, only the movement of the first and second bending members 120a and 120b in the upward and downward directions Z may be adopted. The sliding member 122 is forcibly performed, and is configured to move in the left-right direction Y by a biasing means. Alternatively, a configuration in which the movement in the left-right direction Y of the first and second bending members 120a and 120b is performed by the sliding member 122 and the movement in the up-down direction Z by a biasing means may be adopted. In either case, the guide functions of the pair of guide surfaces 123a and 123b can be combined to smoothly drive the first and second bending members 120a and 120b.

[About the forming structure and effect of the non-metallic needle 2 of the forming mechanism and the press needle mechanism]

(Configuration 1) As described above, the binding machine 1 of this embodiment includes a forming mechanism (forming member 102), which is formed by bending and forming a flat non-metal needle. Zigzag shape; and pressure needle mechanism (pressure needle plate 92), which is held to form Pins 2b, 2c of the non-metallic pin 2 in a zigzag shape.

The forming mechanism and the press needle mechanism are exchanged to form Zigzag of non-metal needle 2.

The forming mechanism and the pressing needle mechanism are arranged on the non-metal needle 2 and can be bent along the non-metal needle 2 The direction of the glyph is relatively moved, and the forming mechanism and the press needle mechanism are provided so as to be movable relative to each other.

The forming mechanism is configured to relatively move the non-metal needle 2 and the pressing mechanism, and bend the non-metal needle 2 in the moving direction.

The needle press mechanism is configured to bend the non-metal needle 2 into In the shape of the figure, it is retracted to a position where it does not contact the bent pins 2b, 2c, and it is formed after receiving the bent When the non-metal needle 2 in the shape of a letter is moved relatively to the non-metal needle 2, it is held to form Pins 2b, 2c of the non-metallic pin 2 in a zigzag shape.

(Effect 1) According to this configuration, the forming mechanism is formed along the non-metal needle 2 The zigzag direction moves relatively to form the non-metal needle Glyph. At this time, since the presser mechanism is retracted to a position where it is not in contact with the pins 2b, 2c, the formation can be reduced. The load on pins 2b and 2c in the font. After forming, the needles 2b and 2c can be held by being relatively moved in the direction of the non-metallic needle 2 by the needle pressing mechanism. In this manner, the non-metallic needle 2 can be formed and exchanged by merely moving the forming mechanism and the presser mechanism relative to the non-metallic needle 2. In addition, the pins 2b and 2c are held by the needle pressing mechanism, thereby maintaining the pins 2b and 2c. The shape of the shape can suppress the deformation of the pins 2b and 2c. Therefore, the non-metallic needle 2 can be formed more stably.

(Composition 2) The forming mechanism is formed by bending a non-metal needle 2 The shaped forming member 102 may also have a pair of arm portions 102a. The pair of arm portions 102a is formed by bending the non-metal needle 2 and forming it. The direction of the zigzag shape extends substantially parallel, and the pins 2b and 2c are bent and held to form A pair of pins 2b, 2c of a chevron-shaped non-metallic needle.

The pair of arm portions 102a is elastically deformable in a direction in which the space between the pair of arms is enlarged and contracted, and is configured to hold the distance between the front ends (protrusions 102b) of the front ends of the pair of pins 2b and 2c so as to form an interval ratio. One of the non-metallic needles 2 in the shape of a pair of pins 2b, 2c is more narrowly spaced.

(Effect 2) According to this configuration, when the pins 2b and 2c are held by the pair of arm portions 102a, the tip ends (protrusions 102b) which are narrower than the interval between the pins 2b and 2c are used to close the needle tips slightly inward. Therefore, even if the stitches 2b, 2c are slightly deformed, the needle tip can be easily picked up by the needle pressing mechanism, and the non-metallic needle 2 can be formed more stably.

(Configuration 3) The pressing needle mechanism may include a pair of pressing needle portions 105, and the pair of pressing needle portions 105 may be formed by One of the non-metallic needles 2 in the shape of a letter is arranged at the insertion interval of the pins 2b, 2c. The non-metallic needle 2 is moved relatively, and a pair of pins 2b, 2c is taken in and held inside.

This pin presser 105 is configured to hold the pair of pins 2b and 2c in the pair of arm portions 102a when receiving the non-metal pin 2 from the forming mechanism, and it is preferable to hold the tips of the pair of pins 2b and 2c.

(Effect 3) According to this configuration, only the pressing needle mechanism is relatively moved with respect to the non-metallic needle 2 and the pair of pins 2b and 2c are inserted into the pair of pressing needle portions 105 to be reliably held. In addition, before the non-metallic needle 2 is released from the arm portion 102a, the pins 2b and 2c are held by the pressing needle portion 105, thereby suppressing the opening of the pins 2b and 2c and maintaining the pins 2b and 2c. As a result, the non-metallic needle 2 can be formed more stably. In addition, it is not necessary to perform the opening and closing operation of the pressing needle portion 105, or to provide members required for the opening and closing operation, and it is possible to simplify the formation. The configuration of the zigzag or press pin mechanism or the reduction of the number of components can provide a low-cost binding machine 1.

(Composition 4) At least one of the pressing mechanism and the forming mechanism may have an engaging portion (elastic piece 106). When the non-metallic needle 2 is exchanged between the forming mechanism and the pressing mechanism, the Engage with the other side so as to move relatively integrally.

(Effect 4) According to this configuration, for example, the engagement of the engaging portion is released, and only the forming mechanism is relatively moved to the non-metal needle 2, whereby the non-metal needle 2 can be formed by the forming mechanism. After the forming, the forming mechanism is engaged with the press pin portion by the engaging portion, and is relatively moved integrally with one another, thereby being held in the forming mechanism and formed. In the state of the non-metallic needle 2 in a zigzag shape, the needle pressing mechanism can hold the pins 2b and 2c. Therefore, the opening of pins 2b and 2c is suppressed, and it is possible to maintain The character state enables smoother and more reliable exchange of the non-metallic needle 2 and more stable forming.

(Configuration 5) A penetrating mechanism 37 having a pair of pins 2b, 2c of the non-metallic needle 2 and a pair of penetrating blades 36a, 36b of the paper P may be included, and a forming mechanism may be provided integrally with the penetrating mechanism 37.

(Effect 5) According to this configuration, the forming mechanism can be operated in conjunction with the penetrating mechanism 37, and the number of components can be reduced. Therefore, the installation space of the forming mechanism and the like can be reduced, and the size of the binding machine 1 can be reduced.

(Configuration 6) The forming mechanism may be housed inside the presser mechanism so as to be relatively movable.

(Effect 6) According to this configuration, the volume of the forming mechanism and the presser mechanism can be made smaller, and the size of the binding machine 1 can be reduced. In addition, in the needle press mechanism, the forming mechanism can be moved relatively, the movement range of the forming mechanism is limited to a desired range, and movement control can be easily performed.

[About the guide structure and effect of the penetrating blades 36a, 36b of the penetrating blade guide 117]

(Composition 1) As described above, the binding machine 1 of this embodiment includes a penetrating mechanism 37 having a pair of penetrating blades 36a and 36b for penetrating a pair of pins 2b and 2c of the non-metal needle 2 through the paper P; The bending mechanism 38 bends the stitches 2b and 2c along one of the penetrating sheets P along the sheet P. In addition, it includes a penetrating blade guide 117 that guides the inner side of one pair of penetrating blades 36a, 36b of the penetrating paper P.

The penetrating blade guide 117 is located between the pair of penetrating blades 36a and 36b, and includes: a first guide portion 117a that guides the portion penetrating through the paper P of the penetrating blades 36a and 36b; and a second guiding portion 117b is a part of the guide penetrating blades 36a, 36b which penetrates the portion from the paper P.

Before the pair of penetrating blades 36a and 36b penetrate the paper P and before the bending mechanism 38 bends the stitches 2b and 2c, the first guide portion 117a is positioned between the penetrating blades 36a and 36b and guides the penetrating blades 36a and 36b. 36b, and when the pair of penetrating blades 36a, 36b penetrate the paper P, and the bending mechanism 38 bends the pins 2b, 2c, the second guide portion 117b is positioned between the penetrating blades 36a, 36b, and guides the penetrating blade 36a , 36b.

(Effect 1) According to this configuration, before the pair of penetrating blades 36a and 36b penetrate the paper P and the bending mechanism 38 bends the pins 2b and 2c, the penetrating blade of the penetrating paper P is guided by the first guide portion 117a. 36a, 36b Subsidiary Paper P The penetrating portion can suppress the displacement (deformation) of the penetrating blades 36a and 36b inward. When the pair of penetrating blades 36a and 36b penetrate the paper P and the bending mechanism 38 bends the pins 2b and 2c, the second guide portion 117b guides the portion penetrated by the paper P through the penetrating blades 36a and 36b. It is possible to suppress the jitter of the penetrating blades 36a and 36b in the left-right direction Y or the deformation inward.
