Specifically, since the position (reference position) of the contact surface 346a is unchanged from the position of the hand unit 34 and can be grasped in advance, the position of the contact unit 346a and the reference surface can be determined by moving the hand unit 34 to any position. Can also be grasped in advance. Therefore, if the hand unit 34 is moved to the position, the contact surface 346a can be arranged on the reference surface with high accuracy regardless of the size or type of the booklet D. In addition, since the swing fixing means 348 can be prevented from swinging in the fixed state described above, the contact surface 346a is arranged on the reference surface with high accuracy without the booklet D swinging during conveyance. It becomes possible to do.

  The above-mentioned predetermined reference position can be set in advance. As described above, the abutting plate 346 is moved together with the inner plate at the time of fixing using the function of the swing fixing means 348, that is, when the pressure is applied by the pressing means. The position of the contact surface 346a after the movement may be set as a predetermined reference position.

  As described above, according to the present embodiment, the booklet D can be accurately grasped and controlled by performing the specific control using the function of the rocking and fixing means 348, which is the function of making the plate 348b free and locking with air pressure. Positioning is realized. A specific method for gripping the booklet D will be described in a booklet receiving method described later.

Further, according to the bookbinding information, the cutting means 36 is controlled by a cutting control signal, and the booklet D is cut on the top, the ground, and the front edge.

  Below, the booklet reception method of the three-way cutting machine 30 is demonstrated using FIGS. 15-17. The booklet receiving method bears one end of the booklet transport method according to the present embodiment.

  First, the control unit 40 finishes the rotation control of the moving unit 22a of the delivery machine 20, and moves the moving unit 32a to the upper side of the delivery machine 20 after determining that the back of the booklet D faces upward. Next, the moving unit 32a is moved downward in the vertical direction (in the direction of the contact plate 346) while the hand unit 24 of the transfer machine 20 is gripping both the top and bottom ends of the booklet D, and FIG. 16A, the contact surface 346a of the contact plate 346 of the hand unit 34 and the back of the booklet D are brought into contact with each other. In FIG. 16, for the sake of explanation, the swing fixing means 348 is simply shown, and the clamp plate 342 is omitted.

  In this state, the back of the booklet D is urged by the contact plate 346 by further moving the moving part 32a downward in the vertical direction. Since the plate 348b can move in the direction of the frame 348a by the gap, the swing fixing means 348 makes the frame 348a and the plate 348b contact each other as shown in FIG. It becomes. In this state, the urging of the contact plate 346 to the back of the booklet D is continued. Next, the control unit 40 drives the clamp actuator 344 of the hand unit 34 to move the clamp plates 342 toward each other, and grips the back end portion of the booklet D. After gripping, the hand unit 24 of the transfer machine 20 releases the booklet D as described with reference to FIG. 11, and moves (withdraws) in directions away from each other. As a result, the booklet D is brought into a state as shown in FIG. 16C held only by the hand unit 34, and the contact surface 346a is arranged at a predetermined reference position and is kept horizontal. In this state, naturally, the contact plate 346 is not biased to the back of the booklet D.

  In this state, since the booklet D is gripped only by the hand unit 34, the contact plate 346, the clamp plate 342, and the booklet D can be swung by the swinging fixing means 348, in other words, suspended from the moving part 32a. It is in a lowered state. Therefore, each time the moving part 32a moves in the transport direction, for example, the contact plate 346, the clamp plate 342, and the booklet D swing at least along the transport direction due to the inertial force thereof. In such a state, in the cutting means 36 located in the subsequent stage, the contact surface 346a and the reference surface cannot be made to coincide with each other accurately, and the edge of the booklet D cannot be cut accurately.

  Therefore, as shown in FIG. 16 (d), the controller 40 moves by applying air pressure from the joint 348c to pressurize the swing fixing means 348 and fix the plate 348b by the pressurizing means 348d. The contact plate 346 is fixed to the portion 32a.

  In the case of the hand unit 24 as described above, for example, as shown in FIG. 17A, the delivery machine 20 cannot accurately grip the booklet D, and even if the back of the booklet D is inclined, it will contact. The surface 346a can be horizontally arranged at the reference position, and the booklet D can be gripped with extremely high accuracy and accuracy.

  Specifically, since the plate 348b of the swing fixing means 348 can swing, the plate 348b tilts in accordance with the back tilt of the booklet D as shown in FIG. The surface 346a and the back of the booklet D can be brought into contact with each other. In this state, the back of the booklet D can be urged by the contact plate 346 by further moving the moving part 32a downward in the vertical direction. In this state, the control unit 40 causes the hand unit 34 to grip the back end of the booklet D, and the hand unit 24 of the transfer machine 20 is retracted. Thereby, the booklet D can be made the same as the state shown in FIG. 16C held only by the hand unit 34.

  In the state shown in FIG. 17A and FIG. 17B, the back of the booklet D is inclined, so that the center of gravity of the booklet D may deviate from the center of gravity of the contact plate 346. However, the contact plate 346 can be fixed without swinging by the swing fixing means 348, and the contact surface 346a can be arranged at the reference position and kept horizontal. As described above, if the booklet D is gripped with high accuracy by the hand unit 34, the end faces can be accurately trimmed by the cutting means 36 located at the subsequent stage.

  Next, a method for cutting the booklet D in the cutting means 36 will be briefly described.

  When the booklet D is gripped by the hand unit 34 as shown in FIG. 16 (d) and conveyed to the front edge cutting unit 36a, the cutting position is positioned at the reciprocating position of the cutting blade of the unit. The control unit 40 controls the positioning actuator 32 so that the booklet D is brought into contact with the contact surface, and the booklet D is pressed by the press plate to press the booklet D. Here, as described above, the contact surface 346a of the contact plate 346 is positioned horizontally and at the reference position, and is accurately disposed on the reference surface. Therefore, the cutting position is set to the reciprocating position of the cutting blade with high accuracy. Can be arranged. Thereafter, the control unit 40 controls the cutting blade of the front fore edge cutting unit 36a, whereby the booklet D is cut at the cutting position, and the end surfaces of the front fore edge are aligned.

  Next, the booklet D is gripped by the hand unit 34 and conveyed to the top cutting unit 36b. At this time, the detection means detects the top end surface (or the ground side or both) of the booklet D, and the control unit 40 recognizes that the detected end surface is the reference surface. Thereafter, the booklet D is cut at the cutting position using the contact surface of the unit, the press plate, and the cutting blade in the same manner as the cutting unit 36a for the front edge, and the end surfaces of the front edge are aligned. By carrying out this operation also in the ground cutting unit 36c, the top, the ground, and the front edge side end face of the booklet D can be accurately aligned.

(Application 1)
In the present embodiment, it has been described that the hand unit 34 having a compliance module is used as the swing fixing means 348. However, the present invention is not limited to this, and the contact plate 346 is supported so as to be swingable and vertically movable. In addition, any hand unit provided with a mechanism capable of fixing it appropriately may be used. For example, as shown in FIG. 18, a hand unit 34 a including a swing fixing means 38 may be used instead of the swing fixing means 348.

  Like the swing fixing means 348, the swing fixing means 38 provided in the hand unit 34a is supported by the moving portion 32a, and the contact plate 346 is swingable with respect to the Z-axis direction (vertical direction). It is supported so that it can move up and down along the axial direction. The rocking and fixing means 38 and the rocking and fixing means 348 are different in configuration. Specifically, the rocking and fixing means 38 is an elastic member provided between the moving portion 32a and the contact plate 346. A spring part 38a that is a body, a piston 38b that supports the contact plate 346 in a swingable manner in the Z-axis direction, and a cylinder 38c that is provided in the moving part 32a and slidably accommodates the piston 38b. Has been.

  The spring portions 38a are disposed at least on both sides of the piston 38b so that the spring 38a can be compressed or expanded in the vertical direction when the contact plate 346 swings around the piston 38b. It constitutes one end of the function that enables rocking and vertical movement. The spring portions 38a are preferably disposed at the four corners of the contact plate 346. When the contact surface 346a contacts the back of the booklet D, the contact plate 346 is aligned along the inclination of the back of the booklet D. It preferably has an elastic force that can be easily swung. As long as it has such an elastic force, an elastic body such as a thin plate of rubber or plastic may be used instead. In FIG. 18, the spring portions 38a are arranged at the four corners of the contact plate 346. However, the present invention is not limited to this, and a function that enables the contact plate 346 to swing and move up and down is realized. If possible, the number and position are appropriate.

  The piston 38b can move up and down in the cylinder 38c and is swingably connected to the contact plate 346. The piston 38b serves as one end of a function that enables the contact plate 346 to swing and move up and down. Yes. That is, the contact plate 346 can swing with the connecting portion between the contact plate 346 and the piston 38b as a fulcrum.

  The cylinder 38c that accommodates the piston 38b is connected to negative pressure means (not shown) such as a vacuum pump that generates negative pressure therein, and the negative pressure means is driven to generate negative pressure inside the cylinder 38c. Thus, the piston 38b can be pulled up vertically (in the direction of the moving part 32a). As a result, the contact plate 346 can be pulled toward the swing fixing means 38. In FIG. 18, one piston 38 b and one cylinder 38 c are provided at the center of the contact plate 346, but the present invention is not limited to this, and a function that enables the contact plate 346 to swing and move up and down. If it can be realized, the number and position thereof are appropriate.

  Since the contact plate 346 is supported by the moving portion 32a via the swing fixing means 38, it is in a so-called suspended state that can be easily swung in a normal state where the negative pressure means is not driven. However, since the spring fixing unit 38 pulls the piston 38b upward in the vertical direction, the spring portion 38a is compressed, so that the contact plate 346 can be fixed to prevent the swinging. The position of the contact surface 346a of the contact plate 346 in this fixed state is unchanged even if the size of the booklet D is changed. Therefore, even if the swing fixing means 38 is used, the contact surface 346a can be set as the reference position as in the present embodiment.

  If such a hand unit 34 a is used, the booklet D can be accurately grasped similarly to the hand unit 34. The gripping method will be briefly described. First, as shown in FIG. 19A, the contact surface 346a of the contact plate 346 of the hand unit 34a and the back of the booklet D are contacted. Further, the back of the booklet D is urged by the contact plate 346 by moving the moving portion 32a downward in the vertical direction.

  Accordingly, as shown in FIG. 19B, the spring portion 38a is compressed and the piston 38b is slid upward in the cylinder 38c. In this state, the control unit 40 moves the clamp plates 342 toward each other to grip the back end of the booklet D. After gripping, the hand unit 24 of the transfer machine 20 releases the booklet D and retreats. As a result, the booklet D is in a state as shown in FIG.

  In this state, since the booklet D is held only by the hand unit 34 a, the contact plate 346, the clamp plate 342 and the booklet D can be swung by the swing fixing means 38. Therefore, as shown in FIG. 19D, the control unit 40 causes the negative pressure means to generate a negative pressure in the cylinder 38c and pulls the contact plate 346 and the booklet D together with the piston 38b upward in the vertical direction. By uniformly compressing the two spring portions 38a, the contact plate 346 is drawn toward the moving portion 32a. As a result, the contact plate 346 is fixed without swinging, and the contact surface 346a is arranged at the reference position and is kept horizontal. It is preferable that the lower surface of the moving portion 32a and the upper surface of the contact plate 346 are parallel so that the lower surface of the moving portion 32a is always horizontal so that it can be kept horizontal. Further, the position where the contact plate 346 is fixed is preferably a position where the spring portion 38a is completely compressed.

  With the hand unit 34a as described above, for example, as shown in FIG. 20A, the contact surface 346a can be arranged horizontally at the reference position even when the back of the booklet D is inclined, and the accuracy is extremely high. The booklet D can be gripped well and accurately.

  Specifically, as shown in FIG. 20 (b), the contact plate 346 causes the contact surface 346 a to contact the back of the booklet D in accordance with the back of the booklet D by the swing fixing means 38. be able to. In this state, the back of the booklet D can be urged by the contact plate 346 by further moving the moving part 32a downward in the vertical direction. In this state, the control unit 40 grips the back end of the booklet D by the hand unit 34a, and the hand unit 24 of the transfer machine 20 is retracted. As a result, the booklet D is in the state shown in FIG.

  In the state shown in FIG. 17C, the back of the booklet D is inclined, so that the center of gravity is shifted as indicated by the symbol E. However, by pulling the contact plate 346 to the moving part 32a by the swing fixing means 38, the contact plate 346 can be fixed without swinging, and the contact surface 346a is arranged at the reference position even when the center of gravity is shifted. And can be kept horizontal.

(Application example 2)
It has been described that the rocking and fixing means 348 and 38 in the present embodiment can be accurately gripped even if the booklet D is gripped by the transfer machine 20 with the function thereof being inclined. However, when the booklet D is tilted beyond the structural swing limit range of the swing fixing means 348 and 38, there is a possibility that it cannot be gripped accurately. In such a case, the transfer machine 20 may be provided with a sensor to determine whether or not the inclination of the booklet D exceeds the swing limit range on the structure of the swing fixing means 348 and 38. Hereinafter, the determination method will be described with reference to FIG. In FIG. 21, only the booklet D, the pair of clamp plates 242 and the pair of sensors 26 of the hand unit 24 are illustrated for the sake of explanation.

  For example, as shown in FIG. 21 (a), a pair of non-contact sensors 26 are provided linearly, preferably horizontally, above the hand unit 24 (in the Z-axis direction), and the back of the booklet D faces upward. In the state of facing (the state after rotation of the booklet D), the hand unit 24 is moved to a predetermined position in the direction of the sensor 26. The predetermined position is set in advance based on the bookbinding information. Specifically, there is an interval from the back of the booklet D to the sensing range of the sensor 26 with the hand unit 26 disposed at the position. It is set as follows. This distance is preferably a length based on the rocking limit range in the structure of the rocking and fixing means 348 and 38. For example, the structure in which the rocking and fixing means 348 and 38 can rock 0.5 mm in the vertical direction. If so, this interval is set to 0.5 mm.

  After the hand unit 24 moves to a predetermined position in the direction of the sensor 26, the control unit 40 uses the sensor 26 to determine whether any of the at least two sensors 26 has responded, that is, to detect any of the sensors 26. It is determined whether or not an intruder (booklet D in this case) has entered the range. As shown in FIG. 21B, when neither of the two sensors 26 reacts, the control unit 40 determines that the inclination of the booklet D is within the swing limit range of the swing fixing means 348 and 38. The determination is made and the process proceeds to gripping the booklet D by the hand unit 34 of the three-way cutting machine 30.

  On the other hand, as shown in FIG. 21 (c), when there is a response to one of the two sensors 26, the control unit 40 determines that the inclination of the booklet D is within the swing limit range of the swing fixing means 348 and 38. It is determined that it has exceeded, and the cutting of the booklet D is interrupted or the booklet D is discarded. Here, if the bookbinding system 1 includes a display, a speaker, and the like, it is preferable that an error display on the display or an alarm be sounded to notify the user.

  By using such a sensor 26, it is possible to move to the next step only when the inclination of the booklet D is within the structural swing limit range of the swing fixing means 348, 38. Productivity can be improved.

  As shown in FIG. 21 (c), it may be determined that the inclination of the booklet D is within the swing limit range of the swing fixing means 348, 38 in a state where the two sensors 26 have reacted together. Good. In this case, if the sensing range is set to 0.5 mm, the inclination of the booklet D exceeds the swing limit range of the swing fixing means 348 and 38 when there is no response to either of the two sensors 26. By determining, the same effect can be obtained. Further, the inclination of the booklet D is calculated based on the movement distance of the hand unit 24 until it is detected by one of the two sensors 26, and whether the calculation result is within the swing limit range. You may make it determine.

  If the inclination of the booklet D is determined with the back of the booklet D facing downward, the sensor 26 may be provided below the hand unit 24, but the contact surface 346a is disposed on the reference surface. In view of this, it is preferable that the booklet D is provided above the hand unit 24 so that the back portion can be determined with the spine facing upward. Moreover, although it demonstrated that the hand unit 24 was moved to the direction of the sensor 26, you may move a pair of sensor 26 to the hand unit 24 direction. Further, although the sensor 26 has been described as a non-contact type, it is needless to say that the sensor 26 may be a contact type.

  Further, in the present embodiment, it is described that the bookbinding apparatus described in Patent Document 1 is used as the wireless binding machine 10 and a part of the cutting machine described in Patent Document 2 is used as a part of the three-way cutting machine 30. It is not limited to this. Needless to say, the present invention can be applied to any apparatus that uses a hand unit to perform bookbinding operations and booklet edge cutting.

  Moreover, although the reference plane has been described as being horizontal, the present invention is not limited to this. For example, even if the cutting blade of the front edge cutting unit 36a is vertical and the reference surface is vertical, if the transfer machine 20 or the hand unit 34 is installed in a state rotated by 90 °, the contact plate 346 will be contacted. The contact surface 346a can be easily placed vertically on the reference surface. In this case, the booklet D is gripped by the hand unit 34 with the top end face facing upward and the ground end face facing downward.

  In addition, although the control unit 40 is shared by the wireless binding machine 10, the transfer machine 20, and the three-way cutting machine 30, a control unit may be provided in each device so that these control units can control each unit independently and in cooperation. Good.

  Further, it has been described that the hand unit 24 of the transfer machine 20 grips the booklet D by the pair of clamp plates 242 being moved in a direction in which they approach each other. However, the interval between the pair of clamp plates 242 may be fixed in advance to be approximately the same as the back width of the booklet D, and the wireless binding machine 10 may insert the booklet D into the interval.

  The present invention can be implemented in various other forms without departing from the gist or main features thereof. Therefore, the above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. The scope of the present invention is shown by the scope of claims, and is not restricted by the text of the specification. Moreover, all modifications, various improvements, substitutions and modifications belonging to the equivalent scope of the claims are all within the scope of the present invention.
