Description

  The present invention relates to a binding part that is unfolded before processing and is fitted into a ring shape after processing and forms a booklet by binding holes punched in each of a plurality of sheets. Specifically, the binding part of the binding component has a taper formed at the portion that abuts on the coupled part to be fitted, so that friction between the coupled part and the coupled part can be reduced during fitting. In addition, the load applied to the left and right development parts of the binding component can be reduced so that the fitting accuracy can be improved.

  In recent years, a paper processing apparatus that performs punching and binding processing on a paper on which an image is formed is often used in combination with a black-and-white and color copiers and printing apparatuses. In this case, the paper on which the image is formed by a copying machine or the like is punched, and the binding component is automatically inserted and fitted into the hole of the punched paper.

  For example, the binding component used at this time is manufactured by resin injection molding, and includes a spine portion and a plurality of rings arranged and fixed on the spine portion. This ring is unfolded before processing and becomes a ring after processing. The binding component is held and fixed by a holding unit that holds the binding component. The binding component that is held and fixed is pressed from the outside of each ring of the binding component by a fitting portion that fits the binding component, and is fitted into the hole of the sheet to form an annular shape.

  In connection with such a conventional example, the applicant of the present invention has previously proposed a binding device described in Patent Document 1. According to the binding component used in this binding device, a plurality of ring portions are arranged at regular intervals on the spine portion. This ring part has the 1st and 2nd division | segmentation ring part connected so that bending right and left was possible. Each of the coupling portions provided at the tips of these split ring portions is fitted to form a ring portion in an annular shape.

JP 2007-076194 A (FIGS. 8 to 10)

  By the way, according to the binding component described in Patent Document 1 according to the conventional example, the first and second coupling portions provided in the left and right split ring portions are fitted to form the ring portion in an annular shape. The first coupling portion includes a hook portion protruding in the center and lower guide portions on both sides thereof. These lower guide portions are formed so that the tips of the lower guide portions are substantially perpendicular to the rotation direction about the hinge. Moreover, the 2nd coupling | bond part is equipped with the nail | claw part in the center and the upper guide part on the both sides. When the claw portion is hooked on the hook portion and the first and second coupling portions are fitted, the lower guide portion and the upper guide portion slide and guide.

  At this time, there is a problem that the tip of the lower guide portion formed substantially at right angles comes into contact with the inner side of the upper guide portion and friction between the lower guide portion and the upper guide portion increases. Due to this friction, when binding the binding component, a load is applied to the left and right split ring portions, and the split ring portions may be deformed. This is due to the fact that the rigidity of the split ring portion is less than the fitting load of the binding portion of the binding component. In particular, in resin materials that are easily affected by temperature changes, the split ring part is deformed because the rigidity of the split ring part is significantly reduced when binding components are generally fitted in a high temperature environment. Often to do. When the split ring portion is deformed, there is a problem that the fitting accuracy of each of the coupling portions is lowered. In particular, when the ring diameter of the binding component is increased, it is difficult to maintain the rigidity of the split ring portion, and the possibility that the binding component is deformed increases.

  Accordingly, the present invention solves the problems related to the conventional example, and provides a binding component that can reduce the load applied when the binding component is fitted and can improve the fitting accuracy. The purpose is to do.

  In order to solve the above-described problem, the binding component according to the present invention is a binding component that is unfolded before processing and becomes a ring shape after processing, and forms a booklet by binding holes punched in each of a plurality of sheets. A plurality of first and second developed portions for rings arranged on both sides of the spine portion, and a coupling portion is provided at a distal end of the first deployed portion, 2 is provided with a coupled part fitted to the coupling part at the tip of the developed part, and the coupling part has a tapered portion in which a part contacting the coupled part is tapered. It is a feature.

  The binding component according to the present invention is a component that is unfolded before processing and fitted into a ring shape after processing, and a plurality of first and second unfolding portions for the ring are provided on both sides of the spine portion. It is arranged. A coupling portion is provided at the distal end of the first deployment portion, and a coupled portion that is fitted to the coupling portion is disposed at the distal end of the second deployment portion. The coupling portion and the coupled portion are abutted and fitted. In this case, for example, the tapered portion of the lower guide portion of the coupling portion comes into contact with the upper guide portion of the coupled portion, and the coupled portion and the coupled portion are fitted. As a result, the friction between the coupling part and the coupled part can be reduced by the taper at the time of fitting, and the load applied to the left and right development parts of the binding component can be reduced.

  The binding component according to the present invention is a component that is unfolded before processing and fitted into a ring shape after processing, and the binding portion of the binding component tapers at the portion that contacts the coupled portion to be fitted. It has a taper formed in a shape.

  With this configuration, this tapered portion can reduce the area where the coupling portion abuts on the coupled portion. Thereby, the friction of a coupling | bond part and a to-be-joined part can be reduced at the time of a fitting. Therefore, when binding the deployed binding component, it is possible to reduce the load applied to the left and right deployment parts of the binding component, so that the deployment unit can be prevented from being deformed. Thereby, the fitting precision of a binding component can be improved.

  A belt unit 62 is disposed at a position where the stacker 63 can be seen. The belt unit 62 receives the booklet 90 whose sending direction is switched by the belt unit 61 and relays the booklet 90, and delivers the booklet 90 to the stacker 63. The stacker 63 accumulates the booklet 90 conveyed by the belt units 61 and 62. In this way, the booklet 90 shown in FIG. 2D is created.

  Next, a paper processing method according to the present invention will be described. 2A to 2D are process diagrams illustrating an example of functions of the binding device 100. The paper 3 shown in FIG. 2A is fed from the upstream side (such as a copying machine) of the binding device 100 and has no punch holes. The sheet 3 is transported toward a predetermined position on the transport path 11 shown in FIG. 1 and decelerated and stopped at a predetermined position on the transport path 11. Thereafter, the conveyance path of the sheet 3 is switched from the conveyance path 11 to the conveyance path 12 by the switchback function, and the sheet 3 is sent in the reverse direction and conveyed to the punch processing unit 20.

  In the punch processing unit 20, as shown in FIG. 2B, a predetermined number of binding punch holes 98 are formed at one end of the paper 3. The sheet 3 ′ with the binding punch holes 98 formed therein is conveyed to the bind sheet aligning unit 30. In the bind paper alignment unit 30, when the preset number of sheets is reached, for example, the position of the binding punch hole 98 is aligned like a sheet bundle 3 ″ shown in FIG. Then, the binding component 43 is inserted into and fitted into the punch hole 98. Thereby, the booklet 90 shown in Fig. 2D in which the binding component 43 is fitted can be obtained.

The binding component 43 illustrated in FIG. 3A is a plan view illustrating a part of the binding component 43. The binding component 43 includes a spine portion 43a, a ring portion 43b, and a pin 43f. The binding component 43 is a resin injection-molded product in which ring portions 43b are arranged at regular intervals on a spine portion 43a having a length corresponding to the size of the standard paper. The ring part 43b includes a first split ring part 43d, a second split ring part 43c, and a third split ring part 43e.

  FIG. 3B is a diagram showing a state seen from the arrow direction B of FIG. 3A. As shown in FIGS. 3A and 3B, the ring part 43b is divided into three parts: a split ring part 43c coupled to the spine part 43a, and a split ring part 43d and a split ring part 43e that are foldably connected to the left and right thereof. It becomes the composition.

  3C is a cross-sectional view taken along the line CC in FIG. 3A. The shape of the cross section of the spine 43a of the binding component 43 shown in FIG. 3C is a convex shape. This convex shape is a shape for making it easy to grip the binding component 43 with the reverse L-shaped binding component gripping claw 41h of the binding component gripping portion 41b of the binding mechanism 41 shown in FIG.

  FIG. 3D shows a state in which a plurality of binding components 43 are stacked as viewed from an arrow direction B in FIG. 3A. 3A to 3C, the split ring portion 43c of the ring portion 43b has a projecting pin 43f. An insertion hole (not shown) corresponding to the pin 43f is provided on the back side of the split ring portion 43c provided with the pin 43f. Thus, in a state where both end portions of the split ring portion 43d, the split ring portion 43c, and the split ring portion 43e are aligned, the pin 43f is inserted into the insertion hole, and the plurality of binding parts 43 are aligned and stacked. be able to.

  A plurality of types of binding components 43 are used in which the diameter of the ring portion 43b differs depending on the thickness of the sheet bundle 3 ″ shown in FIG. 2. Also, the binding component 43 includes the ring portion 43b. The ring part 43d, the split ring part 43c, and the split ring part 43e are divided into three parts. However, the ring part 43b may be divided into n parts (n is a natural number).

  4A to 4C are explanatory diagrams showing an operation example (opening / closing) of the binding component 43, and a state in which the opening / closing operation of the ring portion 43b is seen from the arrow direction B shown in FIG. 3A. As shown in FIGS. 4A to C, the ring portion 43b can be bent at the connecting portion between the split ring portion 43d and the split ring portion 43c, and at the connecting portion between the split ring portion 43c and the split ring portion 43e. . Further, the coupling portion 43g provided at the distal end portion of the split ring portion 43d and the coupling portion 43h provided at the distal end portion of the split ring portion 43e can be coupled.

  Accordingly, the split ring portion 43d, the split ring portion 43c, and the split ring portion 43e are bent in the annular direction by bending the split ring portion 43d and the split ring portion 43e from the state where both end portions of the split ring portion 43c and the split ring portion 43e are substantially aligned. By connecting the connecting portion 43h, a complete ring can be formed. Further, the coupling portion 43g and the coupling portion 43h can be coupled and detached many times, whereby the binding component 43 can be reused. In addition, a plurality of types of binding parts 43 described in FIGS. 3 and 4 are used in which the diameter of the ring portion 43b is different depending on the thickness of the sheet 3 ′ and the sheet bundle 3 ″ illustrated in FIG. .

  FIG. 5 is a schematic diagram illustrating an arrangement example (part 1) of the binder paper alignment unit 30, the binding mechanism 41, and the cartridge. The binding device 100 includes a binding mechanism 41 disposed downstream of the binder paper alignment unit 30 and the cartridge 42 illustrated in FIG. 5, and the binder paper alignment unit 30 and the cartridge 42 radially upstream from the binding mechanism 41. Has an arrangement structure of substantially V-shape.

  The binding mechanism 41 has a binding mechanism rotation shaft 41d. The binding mechanism rotation shaft 41d intersects the direction I for discharging the sheet bundle 3 ″ (see FIG. 2) from the binder paper alignment unit 30 to the downstream side and the direction II for discharging the binding component 43 from the cartridge 42 to the downstream side. It is arranged near the area to be.

  The binder paper alignment unit 30 and the cartridge 42 are arranged on the left side and the right side in a circular arc shape (radially) on the upstream side with respect to the binding mechanism rotation shaft 41d. The binding mechanism 41 operates to reciprocate between the binder paper alignment unit 30 and the cartridge 42. The binding mechanism 41 has an opening 41c at the top of the main body. The binding component take-out position (direction II) is a position where the opening 41c of the binding mechanism 41 takes a posture facing the cartridge 42 side.

  An arrow Y <b> 1 shown in FIG. 5 is the rotation direction of the binding mechanism 41. In this example, if the above-described binding component take-out position (direction II) is the home position (standby position) with reference to the binding mechanism rotation shaft 41d, the binding component 43 is moved counterclockwise from the home position. It rotates to the binding position (direction I) to be bound. On the contrary, it rotates from the binding position to the home position in the clockwise direction.

  For example, in the binding processing unit 40, the binding mechanism 41 moves to the downstream side of the cartridge 42 to receive a binding component 43 (see FIG. 3) having a predetermined size, holds the binding component 43 received from the cartridge 42, and binds. With reference to the mechanism rotation shaft 41d, the sheet rotates in the counterclockwise direction, moves to the downstream side of the binder sheet aligning unit 30, and binds the sheet bundle 3 ″ shown in FIG. In this way, the booklet 90 shown in FIG. 2D can be created by moving the binding component 43 received from the cartridge 42 to the downstream side of the binder paper alignment unit 30 for binding processing.

  In this example, the binding mechanism 41 takes out the binding component 43 from the cartridge 42 when the binder paper alignment unit 30 aligns the paper 3 '. In this way, since the sheet alignment process and the process of taking out the binding component 43 can be performed in parallel, the binding process can be speeded up, and the throughput of the binding apparatus 100 can be improved.

  FIG. 6 is a schematic view showing an arrangement example (No. 2) of the binder paper alignment unit 30, the binding mechanism 41, and the cartridge. The binding mechanism 41 shown in FIG. 6 performs the process of binding the binding component 43 on the paper aligned by the binder paper alignment unit 30, and the binding mechanism 41 at the home position (direction II) shown in FIG. With reference to the mechanism rotation shaft 41d, it is rotated in the counterclockwise direction indicated by the arrow Y1 and moved to the binding position (direction I). Here, the binding position is a position where the opening 41c of the binding mechanism 41 takes a posture in which the binder paper alignment unit 30 faces the paper transport direction. According to the binding processing unit 40 shown in FIG. 6, the binding mechanism 41 creates a booklet 90 by binding the binding component 43 to the sheet bundle 3 ″ provided from the binder paper alignment unit 30 at the binding position (direction I). Then, return to the home position (direction II).

The system bus 55 includes an I / O (Input / Output) port 54, an EEPROM (Electrically Erasable and Programmable Read Only Memory) 53, and a RAM (Random Access Memory). 52 and a CPU (Central Processing Unit) 51 are connected. The EEPROM 53 stores a program (binding component acquisition control program) for controlling the operation in which the binding mechanism 41 acquires the binding component 43 and binds the binding component 43 to a sheet. The RAM 52 is used as a work memory when acquiring and controlling the binding component 43 based on the binding component acquisition control program.

  A motor drive unit 44a and a signal processing unit 44b are connected to the I / O port 54. The signal processing unit 44 b binarizes the specified number signal Su output from the external terminal 88 and outputs, for example, 3-bit detection data Du to the CPU 51 via the I / O port 54. The CPU 51 controls the binding mechanism 41 based on the detected detection data Du.

For example, information on the number of sheets of one booklet printed by a copier combined with the binding apparatus 100 is output from the external terminal 88 to the signal processing unit 44b as the specified number of sheets signal Su.

  When the CPU 51 inputs the detection data Du from the signal processing unit 44b and determines that the paper 3 'for one booklet is stored in the paper alignment unit 30 shown in FIG. 5 in a short time, the motor driving unit 44a performs motor control. Data Dm is output and the binding mechanism 41 is controlled to perform the binding process.

  The motor driving unit 44 a is connected to the CPU 51 via the I / O port 54 and further connected to a binding mechanism driving motor 45 a disposed in the binding mechanism 41. The motor driving unit 44a receives the motor control data Dm output from the CPU 51, outputs a binding mechanism driving signal S45a obtained by decoding the motor control data Dm to the binding mechanism driving motor 45a, and drives the motor 45a.

  When the binding mechanism driving motor 45a is driven, the binding component gripping portion 41b shown in FIG. 7 rises to a position where the binding component 43 of the lowest layer stacked on the cartridge 42 (see FIG. 5) can be acquired. Then, the binding component 43 is grasped and lowered.

  After the binding component gripping portion 41b is lowered, the binding mechanism 41 is moved from the home position to the binding position by the rotation of the binding mechanism driving motor 45a (see FIG. 6).

  After the binding mechanism 41 moves to the binding position and stops, the binding component 43 is bound to the punch hole 98 of the sheet bundle 3 ″ provided from the binder paper alignment unit 30 to release the binding component 43. Thereafter, the binding mechanism 41 is released. Moves from the binding position to the home position (see FIG. 5).

In addition, a plurality of binding component gripping claws 41 h for gripping the binding component 43 are provided at the upper end portion of the binding component gripping portion 41 b.

  Further, the binding component gripping portion 41b has a protruding gripping portion link coupling portion 41e on the side surface. The binding part gripping part 41b and the gripping part link 41f are in a state where the gripping part link coupling part 41e is fitted and coupled to the elongated gripping part coupling hole 41i of the gripping part link 41f. The grip portion link 41f is connected to the grip portion cam 41g, and is configured to be rotatable about the grip portion link rotation shaft 41j by rotating the grip portion cam 41g.

  The binding mechanism 41 shown in FIG. 9B shows a case where the binding component gripping portion 41b is moved from the state located at the lowermost part shown in FIG. 9A to the state located at the uppermost part. In this case, the gripping part link 41f is rotated by the binding part driving motor 45a rotating the gripping part cam 41g via a gear and a link mechanism (not shown). As a result, the position and posture of the grip portion coupling hole 41i change, and as a result, the binding component grip portion 41b can move upward as indicated by the arrow direction D via the grip portion link joint portion 41e.

This binding mechanism 41 includes left and right binding claws 41k (an example of a binding member), a first binding claw link 41l, a second binding claw link 41m, and a third as a fitting portion 414 related to the function of binding the binding component 43. A binding claw link 41n, a spring 41o, and a binding claw cam 41p. The left and right binding claws 41k are arranged on both sides of the binding component gripping portion 41b. The first to third binding claw links 41l, 41m, 41n constitute an example of a link mechanism, the second binding claw link 41m constitutes an example of a first binding claw link member, and a third binding The claw link 41n constitutes an example of a second binding claw link member.

  The binding mechanism 41 pushes the arc portion of the binding component 43 in the unfolded state held by the binding component gripping portion 41b inwardly from both outsides by the left and right binding claws 41k to insert the binding component 43 into the punch hole 98 of the sheet bundle 3 ″. Insert both ends and fit.

  Each of the binding claws 41k is rotatably coupled to the first binding claw link 41l by the shaft member 410a and translates left and right. The first binding claw link 41l has a first binding claw link rotation shaft 41r and a first link coupling portion 46j, and is coupled to the second binding claw link 41m via the link coupling portion 46j. ing. The binding claw link 41m includes a second binding claw link coupling hole 41s (an example of a coupling hole) and a second link coupling portion 46k.

  The second binding claw link 41m is coupled to the third binding claw link 41n by the second link coupling portion 46k. The binding claw link 41n includes a third binding claw link rotating shaft 41t and a cam follower 410b. The binding claw link 41n is pushed down via the cam follower 410b by the rotation of the binding claw cam 41p, and rotates counterclockwise about the third binding claw link rotation shaft 41t. Further, the second binding claw link 41m is provided with a spring 41o, and a pulling force is constantly applied to the upper left direction. This is to prevent backlash of the second binding claw link 41m and the like when changing the position of the second binding claw link coupling hole 41s described later, and to increase the accuracy of the binding process. It is also used for the return of the binding claw 41k after the end of binding.

  The second binding claw link coupling hole 41s has, for example, three types of binding parts in order to adjust the pitch (fitting interval) at which the left and right binding claws 41k bind the binding parts 43 according to the diameter size of the binding parts 43. It has a hole corresponding to 43 diameter sizes (large diameter, medium diameter, small diameter). These three types of hole portions are provided in steps so that the distance from the first link coupling portion 46j is different.

  For example, when the diameter of the binding component 43 is small, the pitch L1 (the distance between the left and right binding claws 41k) at which the left and right binding claws 41k bind the binding component 43 is set short. For this purpose, as shown in FIG. 10, the second link coupling portion 46k is set to the upper right hole portion of the second binding claw link coupling hole 41s, and the first link coupling portion 46j and the second The distance from the link coupling part 46k is set short.

  When the diameter of the binding component 43 is large, the pitch L2 (see FIG. 17) at which the left and right binding claws 41k bind the binding component 43 is set longer than the pitch L1. For this purpose, the second link coupling portion 46k is set as the second hole portion from the left with respect to the paper surface of the second binding claw link coupling hole 41s, and the first link coupling portion 46j and the second link coupling are set. The distance with the part 46k is set long.

  Thus, in order to set the second link coupling portion 46k to the second binding claw link coupling hole 41s in accordance with the diameter size of the binding component 43, the switching cam 41u that functions as an example of the adjustment portion and the binding component adjustment Part 46l. The switching cam 41u is driven by a binding component adjusting motor (not shown). The switching cam 41u abuts on a bar member 410c provided in the binding component adjusting portion 46l, and translates the binding component adjusting portion 46l to the left and right. The second binding claw link 41m is rotatably coupled to the binding component adjusting portion 46l via a shaft member 410d.

  When the binding component adjusting portion 46l is translated in the left and right directions, the second binding claw link 41m coupled to the binding component adjusting portion 46l via the shaft member 410d is moved to the left and right with the first link coupling portion 46j as an axis. To turn. As a result, the binding claw link coupling hole 41s of the binding claw link 41m moves to the left and right, and the second link coupling portion 46k is set to one of the three types of holes of the binding claw link coupling hole 41s. The In this way, the second link coupling portion 46k is set to the second binding claw link coupling hole 41s in accordance with the diameter size of the binding component 43.

  FIG. 11 is a cross-sectional view illustrating an operation example (part 1) of the binding mechanism 41. The binding mechanism 41 shown in FIG. 11 is in a state in which the binding component gripping portion 41b waiting in its interior is raised and the small-diameter binding component 43 is taken out from the cartridge 42 shown in FIG. As described in FIG. 9B, the binding component gripping portion 41b is moved up and down by the gripping portion link 41f.

  FIG. 12 is a cross-sectional view illustrating an operation example (No. 2) of the binding mechanism 41. The binding mechanism 41 shown in FIG. 12 is in a state where the binding component gripping portion 41b shown in FIG. 11 is lowered to a predetermined position. The posture of the small-diameter binding component 43 held by the binding component gripping portion 41b is maintained in a substantially horizontal state accommodated in the cartridge 42 shown in FIG. In this state, the split ring portions 43d and 43e of the binding component 43 held by the binding component gripping portion 41b are in contact with the binding portions 41q of the left and right binding claws 41k, respectively. In this state, the left and right binding claws 41k shown in FIG. 12 are not moved.

  FIG. 13 is a cross-sectional view illustrating an operation example (No. 3) of the binding mechanism 41. The binding mechanism 41 shown in FIG. 13 is in a state where the binding component gripping portion 41b shown in FIG. 12 is further lowered. The binding component 43 held by the binding component gripping portion 41b is in a substantially half-stitched state in which the split ring portions 43d and 43e are bound inside and the binding component 43 is half-bound from the substantially horizontal state shown in FIG. Formed (hereinafter referred to as pre-forming).

  When shifting to this preforming, the left and right binding claws 41k of the fitting portion 414 shown in FIG. 13 draws the binding component 43 in the unfolded state (substantially horizontal state) by the binding component gripping portion 41b shown in FIG. The arc part of the binding component 43 in the unfolded state is pressed from both sides. For example, the binding claw cam 41p of the fitting portion 414 slightly pushes down the third binding claw link 41n via the cam follower 410b by the first cam protrusion 410p. When the binding claw link 41n is slightly pushed down, the left and right binding claws 41k are moved inward through the binding claw link 41m and the binding claw link 41l engaged with the binding claw link 41n, and are bound in a deployed state. The split ring portions 43d and 43e of the part 43 are pressed from both outsides to the insides.

  Hereinafter, when shifting to the above-described pre-forming, the left and right binding claws 41k are moved inward and the pitch of the left and right binding claws 41k is narrowed while the binding component gripping portion 41b is lowered (first operation timing). ) And two control methods when the left and right binding claws 41k move inward and the pitch of the left and right binding claws 41k is narrowed (second operation timing) after the binding component gripping portion 41b is lowered. To do.

  The first operation timing for moving the left and right binding claws 41k is controlled by the binding claw cam 41p. By changing the outer peripheral shape of the binding claw cam 41p, the first operation timing for moving the left and right binding claws 41k is controlled.

  14A and 14B are front views showing examples of the shapes of the binding claw cams 41p and 411p. The binding claw cam 41p shown in FIG. 14A is the same as the binding claw cam 41p shown in FIG. 13, and realizes the first operation timing described above. The binding claw cam 41p has a first cam protrusion 410p. This cam protrusion 410p abuts on the cam follower 410b of the binding claw link 41n and pushes down the binding claw link 41n. As a result, the left and right binding claws 41k shown in FIG. 13 are moved inward via the binding claw links 41m and the binding claw links 41l engaged with the binding claw links 41n to narrow the pitch. Operate.

  On the other hand, the binding claw cam 411p shown in FIG. 14B is not provided with the first cam protrusion 410p, and realizes the second operation timing described above. The binding claw cam 411p has the same shape as the binding claw cam 41p shown in FIG. 14A, except that the cam protrusion 410p is not provided.

  The binding claw cam 411p shown in FIG. 14B is not provided with the first cam protrusion 410p. For this reason, the binding claw cam 411p shown in FIG. 14B does not push down the cam follower 410b of the binding claw link 41n at the present time. When the binding claw cam 411p further rotates in the arrow direction D2 from the state shown in FIG. 14B, the binding claw link 41n is pushed down by the second cam protrusion 412p via the cam follower 410b. As a result, the left and right binding claws 41k are moved inward via the binding claw links 41m and the binding claw links 41l engaged with the binding claw links 41n, and operate so as to narrow the pitch. Form.

  As described above, when shifting to the pre-forming, the timing at which the left and right binding claws 41k move is the first timing by the binding claw cam 41p in FIG. 14A than the second operation timing by the binding claw cam 411p in FIG. 14B. The operation timing becomes faster.

  Hereinafter, the first binding timing when the left and right binding claws 41k are moved downward and the pitch of the left and right binding claws 41k is decreased while the binding component gripping portion 41b is lowered, and the binding component gripping portion 41b is lowered. The influence on the binding component 43 by the second operation timing in which the left and right binding claws 41k move inward to narrow the pitch of the left and right binding claws 41k will be described.

  15A to 15C are explanatory views showing an operation comparison example (part 1) of the binding claws 41k of the binding mechanisms 41 and 41 '. The binding mechanism 41 shown in FIG. 15A operates at the first operation timing by the binding claw cam 41p. The binding component gripping portion 41b shown in FIG. 15A shows a state in which the binding component gripping portion 41b is lowered to an intermediate position between the binding component gripping portion 41b shown in FIG. 12 and the binding component gripping portion 41b shown in FIG. In this state, the left and right binding claws 41k shown in FIG. 15A move inward from the state shown in FIG. 12 together with the lowering of the binding component gripping portion 41b when shifting to the preforming shown in FIG. As a result, the binding portion 41q of the binding claw 41k binds the binding component 43 while abutting against the split ring portions 43d and 43e of the binding component 43 removed from the tip.

  The binding mechanism 41 shown in FIG. 15B is an enlarged view of a main part of the binding mechanism 41 in the preforming shown in FIG. 13 when the binding component gripping portion 41b shown in FIG. 15A is further lowered. The left and right binding claws 41k shown in FIG. 15A move inward from the state shown in FIG. 15A with the lowering of the binding component gripping portion 41b when shifting to the pre-forming. As a result, the binding portion 41q of the binding claw 41k comes into contact with the approximate center of the split ring portions 43d and 43e of the binding component 43 that is disengaged from the tip, thereby forming the binding component 43 in a half-stitched state. As described above, since the rigid split ring portions 43d and 43e are pressed against and substantially in the center, the fitting performance can be improved.

  On the other hand, the binding mechanism 41 ′ shown in FIG. 15C is an example that operates at the second operation timing by the binding claw cam 411 p. The left and right binding claws 41k of the binding mechanism 41 'shown in FIG. 15C move inward after the binding component gripping portion 41b is lowered from the state shown in FIG. That is, as shown in FIG. 15C, after the binding component gripping portion 41b is lowered to the substantially bottom dead center, the left and right binding claws 41k have both ends of the binding component 43 held by the binding component gripping portion 41b inward. The half-stitched state of the binding component 43 shown in FIG. 15B is formed by pushing. In this way, the binding portion 41q of the binding claw 41k shown in FIG. 15C abuts on the substantial tip of the split ring portions 43d and 43e of the binding component 43 to form the binding component 43 in a half-stitched state.

  As described with reference to FIG. 3, the coupling portions 43 g and 43 h provided at the ends of the split ring portions 43 d and 43 e are fitted to each other, and the binding component 43 has an annular shape. Accordingly, the coupling portions 43g and 43h are formed thinner than the main bodies (center portions) of the split ring portions 43d and 43e reinforced by the ribs 43q (see FIG. 33B). For this reason, when the binding portion 41q shown in FIG. 15C abuts on the coupling portions 43g and 43h and is pushed inward, the thin coupling portions 43g and 43h are bent inward, and the binding component 43 shown in FIG. There is a possibility that the half-stitched state cannot be formed.

  16A and 16B are explanatory diagrams showing an operation comparison example (part 2) of the binding claws 41k of the binding mechanisms 41 and 41 '. A binding claw 41k shown in FIG. 16A is an enlarged perspective view of the binding claw 41k shown in FIG. 15B. In the binding claw 41k shown in FIG. 16A, the binding portion 41q abuts substantially at the center of the split ring portion 43d of the binding component 43, and the binding component 43 is formed in a half-binding state.

  A binding mechanism 41 'shown in FIG. 16B is an enlarged perspective view of the binding claw 41k shown in FIG. 15C. As shown in FIG. 16B, when the binding portion 41q of the binding claw 41k abuts against the coupling portion 43g of the split ring portion 43d and presses inward, the thin coupling portion 43g is bent inward, and FIG. There is a possibility that the half-binding state of the binding component 43 shown cannot be formed.

  Therefore, in this embodiment, the first operation timing using the binding claw cam 41p is adopted, and the left and right binding claws 41k are moved from the state of the binding component gripping portion 41b shown in FIG. The binding component gripping portion 41b moves downward and moves inward. As a result, the binding portion 41q of the binding claw 41k does not contact the thinly formed coupling portions 43g and 43h but contacts the approximate center of the split ring portions 43d and 43e of the binding component 43. Can be formed in a half-bound state.

  Next, instead of the example of binding the small-diameter binding component 43 described above, an example of binding the large-diameter binding component 43 will be described. FIG. 17 is a cross-sectional view showing an example of the internal configuration of the binding mechanism 41. The binding mechanism 41 shown in FIG. 17 is different from the binding mechanism 41 that binds the small-diameter binding component 43 shown in FIG. 10 in order to bind the large-diameter binding component 43 in the following points. The link coupling part 46k is moved from the upper right hole of the binding claw link coupling hole 41s and is set to the lower left hole.

  Thus, in order to set in the lower left hole, the switching cam 41u rotates about 180 ° counterclockwise, and moves the bar member 410c provided in the binding component adjusting portion 46l to the right. When the binding component adjusting portion 46l moves in the right direction, the binding claw link 41m rotatably coupled to the binding component adjusting portion 46l via the shaft member 410d rotates counterclockwise around the link coupling portion 46j. Rotate. As a result, the binding claw link coupling hole 41s of the binding claw link 41m moves rightward, and the link coupling portion 46k is set to the lower left hole of the binding claw link coupling hole 41s.

  In this way, when binding the large-diameter binding component 43, the distance between the link coupling portion 46j and the link coupling portion 46k is adjusted to be long. Thereby, as described above, the pitch L2 at which the left and right binding claws 41k bind the large-diameter binding component 43 is longer than the pitch L1 at which the small-diameter binding component 43 is bound. Other configurations are the same as those described with reference to FIG.

  FIG. 18 is a cross-sectional view illustrating an operation example (No. 1) of the binding mechanism 41. The binding mechanism 41 shown in FIG. 18 is in a state in which the binding component gripping portion 41b waiting in the interior thereof is raised and the large-diameter binding component 43 is taken out from the cartridge 42 shown in FIG. As described in FIG. 9B, the binding component gripping portion 41b is moved up and down by the gripping portion link 41f.

  FIG. 19 is a cross-sectional view illustrating an operation example (No. 2) of the binding mechanism 41. The binding mechanism 41 illustrated in FIG. 19 is in a state where the binding component gripping portion 41b illustrated in FIG. 18 is lowered to a predetermined position. The posture of the large-diameter binding component 43 held by the binding component gripping portion 41b is maintained in a substantially horizontal state housed in the cartridge 42 shown in FIG. In this state, the split ring portions 43d and 43e of the binding component 43 held by the binding component gripping portion 41b are in contact with the binding portions 41q of the left and right binding claws 41k, respectively. In this state, the left and right binding claws 41k shown in FIG. 19 are not moved.

  FIG. 20 is a cross-sectional view illustrating an operation example (No. 3) of the binding mechanism 41. The binding mechanism 41 shown in FIG. 20 is in a state where the binding component gripping portion 41b shown in FIG. 19 is further lowered. The large-diameter binding component 43 held by the binding component gripping portion 41b has its split ring portions 43d and 43e bound inside to form a half-stitched state from the substantially horizontal state shown in FIG. Forming).

  When shifting to this pre-forming, the left and right binding claws 41k shown in FIG. 20 move down inward and the pitch of the left and right binding claws 41k is narrowed while the binding component gripping portion 41b shown in FIG. 19 is lowered. To work. As a result, the binding portion 41q of the binding claw 41k does not contact the thinly formed coupling portions 43g and 43h but contacts the approximate center of the split ring portions 43d and 43e of the binding component 43. Can be formed in a half-bound state.

  Next, an example of the operation timing of the binding mechanism 41 will be described in time series. In this example, the operation timing of the binding claw 41k of the binding mechanism 41 and the binding component gripping portion 41b will be mainly described. FIG. 21 is a timing chart illustrating an operation example of the binding mechanism 41. The items on the vertical axis of the timing chart shown in FIG. 21 include “HP (home position)”, “timing”, “position of the grip portion 41b”, “spine holding”, “swing”, “binding nails” in order from the top. 41k "and" paper descending link "are shown. In addition, the item on the horizontal axis of the timing chart indicates the rotation angle of the main shaft 412 (see FIG. 23). The main shaft 412 is rotated via a predetermined gear by a binding mechanism driving motor 45a (see FIG. 23), and the binding mechanism 41 shown in FIG. 5 is moved from the home position (direction II) to the binding position (direction I). In the process of moving and returning to the home position (direction II) again, it makes one rotation.

  The item “HP” illustrated in FIG. 21 indicates the timing at which the binding mechanism 41 starts operating. For example, according to the item “HP”, the binding mechanism 41 starts moving from the home position when the rotation angle is “about 15 °”.

  The item “position of the grip portion 41b” illustrated in FIG. 21 indicates the position of the binding component grip portion 41b. For example, according to the item “position of the gripping portion 41b”, the binding component gripping portion 41b has reached the top dead center at the time of the rotation angle “about 40 °” (see FIG. 9B). Thereafter, the binding component gripping part 41 b separates the binding component 43 from the cartridge 42.

  The item “spine holding” shown in FIG. 21 indicates the timing at which the binding component gripping portion 41 b holds the binding component 43. For example, according to the item “hold spine”, the binding component gripping portion 41 b completely holds the binding component 43 at the time of the rotation angle “about 85 °”. At this time, the binding component gripping portion 41b that has reached the top dead center starts to descend.

  The item “swing” shown in FIG. 21 indicates the timing at which the binding mechanism 41 moves from the home position (cartridge 42 side) to the binding position (binder paper alignment unit 30 side). For example, according to the item “swing”, the binding mechanism 41 starts to move from the home position to the binding position at the rotation angle “about 110 °”.

  The item “binding claw 41k” illustrated in FIG. 21 indicates the timing at which the binding claw 41k operates. For example, according to the item “binding claw 41k”, the operation of closing the binding claw 41k in order to form the preforming is started at the time of the rotation angle “about 128 °” (first operation timing). That is, according to the item “position of the gripping portion 41b”, the operation of closing the binding claw 41k is started while the binding component gripping portion 41b reaches the bottom dead center.

  As a result, as described in FIGS. 15A and 15B, the binding claw 41k moves inward from the state shown in FIG. 12 with the lowering of the binding component gripping portion 41b when shifting to the pre-forming. Accordingly, the binding portion 41q of the binding claw 41k abuts substantially at the center of the split ring portions 43d and 43e of the binding component 43 to form the binding component 43 in a half-binding state.

  On the other hand, in the item “binding claw 41k”, the binding claw cam 411p shown by a broken line uses the binding claw cam 411p shown in FIG. 14B instead of the binding claw cam 41p shown in FIG. 14A. In this case, the operation start of closing the binding claw 41k is shown. When the binding claw cam 411p is used, the binding claw 41k starts an operation of closing the binding claw 41k in order to form a preforming at the time of the rotation angle “about 148 °” (second operation timing). .

  When this binding claw cam 411p is used, the operation of closing the left and right binding claws 41k is started approximately 20 ° later than when the binding claw cam 41p is used. That is, according to the item “position of the gripping portion 41b”, the binding claw 41k is started to close when the binding component gripping portion 41b reaches substantially the bottom dead center.

  As a result, as described with reference to FIG. 15C, the binding claw 41 k moves inward from the state illustrated in FIG. 12 after the binding component gripping portion 41 b is lowered when shifting to the pre-forming. For this reason, the binding portion 41q of the binding claw 41k shown in FIG. 15C abuts on the coupling portions 43g and 43h of the split ring portions 43d and 43e of the binding component 43 to form the binding component 43 in a half-binding state. Accordingly, when the binding portion 41q shown in FIG. 15C abuts against the coupling portions 43g and 43h and is pushed inward, the thinly formed coupling portions 43g and 43h bend inward, and the binding component 43 of FIG. There is a possibility that the half-stitched state cannot be formed. Therefore, in this embodiment, the binding claw 41k is controlled to operate at the first operation timing using the binding claw cam 41p.

  After the pre-forming is completed, according to the item “binding claw 41k”, the binding claw 41k is punch holes of the sheet bundle 3 ″ provided from the binder paper alignment unit 30 between the rotation angles “about 210 ° to 270 °”. 98, the front end of the binding component 43 is inserted and fitted in. After that, according to the item “HP”, at the time of the rotation angle “about 360 °”, the binding mechanism 41 returns to the home position and ends the binding process. .

  As described above, according to the binding device 100 according to the present invention, the fitting part 414 that fits the binding part 43 into the punch hole of the sheet bundle 3 ″ has the binding part gripping part 41b that holds the binding part 43 in the unfolded state. While pulling the binding component 43 between the binding claws 41k, the binding component 43 is pressed from both sides by the left and right binding claws 41k.

  Therefore, the fitting portion 414 can press the strong arc portion of the binding component 43 in the deployed state by the binding claw 41k. Thereby, since the binding claw 41k does not press the front end portion of the binding component formed to be thin, it is possible to prevent the front end portion of the binding component 43 from being bent. Therefore, the fitting accuracy of the binding component 43 can be improved.

  Next, configurations and operation examples of the binder paper alignment unit 30 and the binding mechanism 41 will be described. FIG. 22 is a front view illustrating a configuration example of the binder paper alignment unit 30 and the binding mechanism 41. The binding mechanism 41 shown in FIG. 22 is located at the home position (direction II) that is the binding component take-out position shown in FIG. Note that a plurality of binding components 43 are stacked and loaded in the cartridge 42.

  The binder paper alignment unit 30 has a clamp moving mechanism 80. The clamp moving mechanism 80 constitutes an example of a clamp portion, and is slidably attached to the left and right guide frames 30a to clamp the sheet bundle 3 ″. In this example, the left and right guide frames 30a include guides. Grooves 30d, 30e, 30f and an upper position restricting portion 30g are provided, and the guide groove 30d is provided at an upper portion of the guide frame 30a, and the guide groove 30e is opened at a substantially central portion of the guide frame 30a. The guide groove 30f is opened at the lower portion of the guide frame 30a, and the guide grooves 30d to 30f have the same long hole shape. The clamp moving mechanism 80 is slidably attached by the member 805 and the connecting shafts 30i and 30j. An upper position defining portion 30g is provided in the vicinity of the guide groove 30e of the cam 30a so that the position can be adjusted, and the upper position defining portion 30g defines the upward movement position of the clamp moving mechanism 80 that is slidably attached. To do.

  In order to raise and lower the clamp moving mechanism 80 slidably attached to the guide frame 30a as described above, the binding mechanism 41 is provided with an elevating part 415. The elevating part 415 is driven by a binding mechanism driving motor 45a (see FIG. 23) and has two upper elevating links 415a facing each other. A connecting shaft 30j provided at the tip of the arm 102 (see FIG. 23) of the clamp moving mechanism 80 is placed on these upper elevating links 415a. When the upper elevating link 415a rotates by a predetermined angle, the clamp moving mechanism 80 placed on the upper elevating link 415a moves up and down while being regulated by the guide grooves 30d to 30f.

  Subsequently, configurations and operation examples of the clamp moving mechanism 80 and the binding mechanism 41 will be described. FIG. 23 is a front view illustrating a configuration example of the clamp moving mechanism 80 and the binding mechanism 41. In order to facilitate understanding of the description, illustration of components such as the guide frame 30a shown in FIG. 22 is omitted.

  The arrangement of the clamp movement mechanism 80 and the binding mechanism 41 shown in FIG. 23 is the same home position as the arrangement of the clamp movement mechanism 80 and the binding mechanism 41 shown in FIG. The binding mechanism 41 includes a binding mechanism driving motor 45a indicated by a two-dot chain line, and is driven by the binding mechanism driving motor 45a.

  The clamp moving mechanism 80 has a pair of L-shaped binding component guide members 99.

Rotate in direction I). For example, in the binding mechanism 41, a spur gear (not shown) coupled to the rotation shaft of the binding mechanism driving motor 45a and a fan gear (not shown) fixed to the binding mechanism 41 are engaged. When the spur gear is rotated by the binding mechanism driving motor 45a, the sector gear rotates, and the binding mechanism 41 binds the binding component 43 counterclockwise with respect to the binding mechanism rotation shaft 41d. Rotate to position (direction I). Note that the binding mechanism rotation shaft 41 d, a spur gear (not shown), and a sector gear constitute a position setting unit 413. The position setting unit 413 obtains a driving force from the binding mechanism driving motor 45a, and sets the position of the main body of the binding mechanism 41 to the home position (direction II) and the binding position (direction I).

  While the binding mechanism 41 is rotated to the binding position (direction I), the binding component gripping portion 41b of the binding mechanism 41 is further lowered from the lowered state while holding the binding component 43 shown in FIG. At the same time, the left and right binding claws 41k of the binding mechanism 41 move inward as described in FIG. 13 to form the preforming of the binding component 43.

  Further, although the elevating part 415 does not rotate around the fulcrum shaft 415k, the position of the connecting shaft 30j of the clamp moving mechanism 80 placed on the upper elevating link 415a is determined by the rotation of the binding mechanism 41. The upper elevating link 415a shown in FIG. 25 moves from the front end to the rear end.

  FIG. 27 is a front view showing an operation example (No. 4) of the clamp moving mechanism 80 and the binding mechanism 41.

The binding mechanism 41 shown in FIG. 30 is in a state in which the binding component 43 is annularly bound while sliding the front end of the binding component 43 on the front surface of the binding component guide member 99 of the clamp moving mechanism 80 by the left and right binding claws 41k. . In this state, the binding component 43 is fitted in the punch hole 98 of the sheet bundle 3 ″.

  FIG. 31 is a front view showing an operation example (No. 7) of the clamp moving mechanism 80 and the binding mechanism 41. The binding component gripping portion 41b of the binding mechanism 41 shown in FIG. 31 is configured so that the binding component gripping claw 41h is rotated by rotation of the binding mechanism driving motor 45a (see FIG. 26) after the binding component 43 is fitted to the sheet bundle 3 ″. Open and release the binding component 43. The binding mechanism 41 releases the held binding component 43, and then rotates the upper lifting link 415a of the lifting unit 415 by the rotation of the binding mechanism driving motor 45a (see FIG. 26) as a fulcrum shaft. It rotates counterclockwise around 415k.

  By the rotation of the upper elevating link 415a, the clamp moving mechanism 80 placed on the upper elevating link 415a is raised to the original position shown in FIG. At this time, the binding component 43 is pulled away from the binding component gripping portion 41b and is fitted into the punch hole 98 of the sheet bundle 3 ″ clamped by the clamp moving mechanism 80. At this point, the booklet shown in FIG. 2D. 90 is formed.

  When the clamp moving mechanism 80 is raised, the fulcrum shaft member 805 and the connecting shafts 30i, 30j are respectively raised in the guide grooves 30d to 30f provided in the guide frame 30a shown in FIG.

  FIG. 32 is a front view showing an operation example (No. 8) of the clamp moving mechanism 80 and the binding mechanism 41. The binding mechanism 41 shown in FIG. 32 uses the position setting unit 413 driven by the binding mechanism driving motor 45a (see FIG. 26) as a reference after forming the booklet 90 shown in FIG. 2D with reference to the binding mechanism rotating shaft 41d. And then return to the home position (direction II) from the binding position (direction I).

  The elevating unit 415 does not rotate about the fulcrum shaft 415k, but the position of the connecting shaft 30j of the clamp moving mechanism 80 placed on the upper elevating link 415a is changed by the rotation of the binding mechanism 41. The upper elevating link 415a shown in FIG.

  Thereafter, the clamp moving mechanism 80 releases the booklet 90 sandwiched between the binding component guide members 99 to drop the booklet 90 in the arrow direction D3, and delivers it to the discharge unit 60 of the post-processing shown in FIG.

  The power transmission mechanism 416 in FIG. 32 that transmits the driving force of the binding mechanism driving motor 45a to the position setting unit 413, the binding component gripping portion 41b, the fitting portion 414, and the lifting / lowering portion 415 is, for example, a binding mechanism driving motor. A gear and link mechanism (not shown) engaged with the rotation shaft 45a, a gripping part cam 41g for driving the binding part gripping part 41b, a gripping part link 41f, and a binding part gripping claw 41h It is composed of a gear and a link mechanism (not shown).

  Accordingly, the binding component 43 can be bound to the sheet bundle 3 ″ with one drive source. As a result, a power failure, jam, or the like occurs in the process of binding the sheet bundle 3 ″ with the binding component 43, causing the apparatus 100 to stop abnormally. In this case, only one binding mechanism driving motor 45a can be reversed or forwardly rotated to easily return from the stopped state. In addition, since the number of drive system parts is reduced, it is possible to realize cost reduction, weight reduction, and size reduction. In addition, since the binding component 43 can be bound to the sheet bundle 3 ″ with one drive source, the control of the binding process can be simplified.

  In addition, when the band apparatus 100 stops abnormally, a method of eliminating conflicting operations by using a plurality of release levers (not shown) is also conceivable.

  Next, the configuration and function example of the binding component 43 will be described. 33A and 33B are perspective views illustrating a configuration example of a main part of the binding components 43 and 43 '. As described in FIG. 3, the binding component 43 shown in FIG. 33A has a plurality of ring portions 43b arranged at regular intervals on the spine portion 43a. The ring portion 43b is divided into three parts: a split ring portion 43c coupled to the spine portion 43a, and a split ring portion 43d and a split ring portion 43e that are connected to the left and right sides of the ring portion 43b. Yes.

  A connecting portion 43g is provided at the tip of the split ring portion 43d, and a connecting portion 43h is provided at the tip of the split ring portion 43e. The first coupling portion 43g and the second coupling portion 43h are coupled, so that the ring portion 43b is annular. The coupling portion 43h includes a claw portion 43n at the center and an upper guide portion 43m on both sides thereof. The upper guide portion 43m guides the coupling portion 43g from above.

  The first coupling portion 43g includes a hooking portion 43j protruding in the center and lower guide portions 43i on both sides thereof. The lower guide portion 43i is in contact with the inner side of the upper guide portion 43m of the coupling portion 43h. In the lower guide portion 43i, the tip of the lower guide portion 43i is formed at an acute angle with respect to the rotation direction around the hinge 43p.

  The binding component 43 ′ shown in FIG. 33B has a split ring portion 43 d ′ different from the binding component 43 shown in FIG. 33A, and the other configuration is the same as the binding component 43. The connecting portion 43g 'of the split ring portion 43d' includes a hooking portion 43j protruding in the center and lower guide portions 43i 'on both sides thereof. These lower guide portions 43i 'are formed so that the tips of the lower guide portions 43i' are substantially perpendicular to the rotation direction about the hinge 43p. Note that the cross section of the split ring portion 43d 'shown in FIG. 33B is formed in a U shape. According to the cross section of the split ring portion 43d ', a reinforcing rib 43q (an example of a reinforcing portion) is provided. Ribs 43q are also provided in the split ring portion 43e and the split ring portion 43d shown in FIG. 33A. The ribs 43q can prevent the split ring portions 43d, 43d ', 43e from being deformed.

  34A and 34B are perspective views showing a configuration example of the coupling portions 43g and 43g '. The lower guide portion 43i on both sides of the coupling portion 43g shown in FIG. 34A has a tapered portion 43k in which a portion of the lower guide portion 43i that contacts the upper guide portion 43m of the coupling portion 43h is tapered at the tip. Have. The tip 43c is cut (cut) obliquely at the tip of the lower guide portion 43i, and is formed at an acute angle with respect to the rotation direction around the hinge 43p shown in FIG. 33A.

  On the other hand, the lower guide portion 43i 'of the coupling portion 43g' shown in FIG. 34B does not have the tapered portion 43k at the tip. The distal end portion 43k 'of the lower guide portion 43i' is formed substantially at right angles to the rotation direction around the hinge 43p shown in Fig. 33B.

  Subsequently, the operations of the binding component 43 and the binding component 43 'are compared. 35A to 35C are perspective views showing an operation example (part 1) of the binding component 43 '. 36A to 36C are front views showing an operation example (part 2) of the binding component 43 '. The binding component 43 ′ shown in FIGS. 36A to 36C is a view of the binding component 43 ′ shown in FIGS. 35A to 35C as viewed from the front. The binding component 43 ′ illustrated in FIGS. 35A and 36A is in a state before the coupling portion 43 g ′ and the coupling portion 43 h are in contact with each other. The binding component 43 ′ shown in FIGS. 35B and 36B is in a state where the lower guide portion 43 i ′ of the coupling portion 43 g ′ and the upper guide portion 43 m of the coupling portion 43 h are substantially in contact with each other.

  The binding component 43 ′ shown in FIGS. 35C and 36C is in a state where the lower guide portion 43 i ′ and the upper guide portion 43 m are slidingly guided to hook the claw portion 43 n on the hook portion 43 j. In this state, the distal end portion 43k 'of the lower guide portion 43i' shown in FIG. 34B is in contact with the upper guide portion 43m.

  The tip part 43k ′ of the lower guide part 43i ′ shown in FIG. 34B is formed substantially at right angles to the turning direction around the hinge 43p shown in FIG. 33B. The friction with the upper guide portion 43m is larger than the tapered portion 43k (see FIG. 34A) of the lower guide portion 43i formed at an acute angle.

  37A to 37C are perspective views illustrating an operation example (part 1) of the binding component 43. FIG. 38A to 38C are front views illustrating an operation example (part 2) of the binding component 43. The binding component 43 illustrated in FIGS. 38A to 38C is a diagram of the binding component 43 illustrated in FIGS. 37A to 37C as viewed from the front. The binding component 43 shown in FIGS. 37A and 38A is in a state before the coupling portion 43g and the coupling portion 43h come into contact with each other. The binding component 43 shown in FIGS. 37B and 38B is in a state where the lower guide portion 43i of the coupling portion 43g and the upper guide portion 43m of the coupling portion 43h are substantially in contact with each other.

  The binding component 43 shown in FIG. 37C and FIG. 38C is in a state where the lower guide portion 43i and the upper guide portion 43m are slidingly guided in order to hook and fix the claw portion 43n to the hook portion 43j. In this guide state, the tapered portion 43k of the lower guide portion 43i shown in FIG. 34A is in contact with the upper guide portion 43m.

  Since the tapered portion 43k of the lower guide portion 43i shown in FIG. 34A is formed in a tapered shape, the distal end portion 43k ′ (FIG. 34B) of the lower guide portion 43i ′ formed substantially perpendicular to the rotation direction. Compared with the reference), the friction with the upper guide portion 43m is reduced.

  Thereby, when binding the binding component 43, the load applied to the split ring portions 43d and 43e pressed by the left and right binding claws 41k can be reduced. Therefore, it becomes possible to prevent the split ring portions 43d and 43e from being deformed by the pressing of the binding claw 41k. Accordingly, it is possible to improve the accuracy of fitting the coupling portion 43g of the split ring portion 43d and the coupling portion 43h of the split ring portion 43e together.

  The locus of fitting of the three-part binding component 43 has a strong tendency to be fitted so that the tip does not fit in the tangential direction but intersects the X shape. Therefore, especially in the binding component 43 divided into three, the advantage of providing the tapered portion 43k in the lower guide portion 43i is great.

  Thus, according to the binding component 43 according to the present invention, it is a component that is unfolded before processing and fitted into a ring shape after processing, and the coupling portion 43g of the binding component 43 is a coupling portion to be fitted. The portion abutting on 43h has a tapered portion 43k formed in a tapered shape.

  Therefore, the area where the coupling portion 43g contacts the coupling portion 43h can be reduced by the tapered portion 43k. Thereby, the friction between the coupling portion 43g and the coupling portion 43h can be reduced during fitting. Therefore, when binding the deployed binding component 43, the load applied to the left and right split ring portions 43d and 43e of the binding component 43 can be reduced, so that the split ring portions 43d and 43e can be prevented from being deformed. Thereby, the fitting accuracy of each of the coupling portions 43g and 43h in the left and right split ring portions 43d and 43e can be improved. In addition, an inexpensive binding component 43 can be provided without selecting a special material.

  As another method for improving the fitting accuracy of the binding component 43, it is conceivable to use a high-rigidity resin as the material of the binding component 43. Further, it is conceivable to increase the thickness of the rib 43q of the binding component 43 or increase the number of the rib 43q.

  It is a component that is unfolded before processing and fitted into a ring shape after processing, and is suitable for binding to a binding component for creating a booklet by binding holes punched in each of a plurality of sheets.
