  The detection means 22 can use an imaging means such as a CCD camera, a light sensor, a proximity sensor, or the like installed on the side of the path of the booklet conveyed by the hand unit 14, and the top or the ground side of the booklet being conveyed. Reference positions such as end faces B2 and B3 are detected, and the detection signals are sent to the control unit 20. As a reference position, an arbitrary reference mark provided on the cover of the booklet may be used instead of the end face of the booklet. Preferably, the detection means 22 may detect a reference position that is closer to the back than the fore edge when the booklet is conveyed, thereby detecting a reference position that is close to the gripping position from the hand unit 14. The detection accuracy can be improved stably.

  Processing in the cutting machine 10 configured as described above will be described. In this example, since the processing in the top and bottom cutting unit 18 is performed next to the processing in the small edge cutting unit 16, the processing in the small edge cutting unit 16 and the top and bottom cutting unit 18 will be described in this order. The order of may be reversed. Further, in this example, the processing in the ground cutting unit 190 is performed after the processing in the general cutting unit 180, but the order of the processing may be reversed.

  First, as shown in FIG. 2, the booklet to be processed is gripped by the hand unit 14 being appropriately moved by the positioning actuator 12. At this time, the spine B1 of the booklet B is pressed against the horizontal reference plane 144 so that the spine B1 of the booklet B is surely positioned on the reference plane 144. Then, the booklet B is gripped by driving the clamp actuator 146 and relatively bringing the clamp plates 142 and 142 closer to each other. When an electric motor is used as the clamping actuator 146, it is possible to detect that the gripping has been properly performed when the torque reaches a predetermined value.

  Next, the control unit 20 outputs a control signal to the positioning actuator 12, and the moving unit 12 a of the positioning actuator 12 moves, so that the surface of the booklet gripped by the hand unit 14 contacts the contact surface 162 of the fore edge cutting unit 16. Contact (FIG. 3A). The vertical direction (Z direction) position of the moving part 12a at this time is the vertical distance from the reciprocating vertical position (known) of the small edge cutting blade 166 to the reference surface 144 of the hand unit 14, and the line from the back of the booklet to the small edge cutting line. It is adjusted to match the distance up to. Note that the distance from the back of the booklet to the edge cutting line is obtained from information on the cutting line in the bookbinding information.

  Preferably, in a state where the vertical position of the moving portion 12a is adjusted, the booklet B is moved in the horizontal direction so that the booklet B comes into contact with the contact surface 162, whereby the booklet B slides with respect to the contact surface 162. Therefore, it is possible to prevent the occurrence of scratches and the like.

  Next, the press plate 168 is moved in the horizontal direction to press the booklet toward the contact surface 162, and in this state, the fore edge cutting blade 166 is moved in the horizontal direction to perform cutting (FIG. 3B). Since the cut chips can fall in the vertical direction, the processing of the chips is easy.

  Thus, the correct position can be cut based on the reference surface 144.

  Next, the control unit 20 outputs a control signal to the positioning actuator 12, the moving unit 12 a of the positioning actuator 12 moves, and the booklet held by the hand unit 14 is conveyed to the top and bottom cutting unit 18. At this time, when passing through the detection means 22, the detection means 22 detects the top side (or the ground side) end face of the booklet and sends a detection signal to the control unit 20. Since the controller 20 knows the position of the moving unit 12a when detected, the position of the hand unit 14 and the position of the detecting means 22 (known), the top and bottom ends of the booklet and the hand unit 14 Distance (horizontal distance) can be calculated. Furthermore, from this distance, the distance from the hand unit 14 to the top and ground side cutting lines S2 and S3 can be calculated based on the information about the cutting line in the bookbinding information.

  Next, as shown in FIG. 4A, the control unit 20 outputs a control signal to the positioning actuator 12, and the moving unit 12 a of the positioning actuator 12 moves to the top cutting unit 180 and is gripped by the hand unit 14. The surface of the booklet is brought into contact with the contact surface 182 of the top and bottom cutting part 18. The horizontal position of the moving part 12a at this time is based on the calculated distance from the hand unit 14 to the top side cutting line S2, so that the top side cutting line S2 coincides with the horizontal position of the reciprocating movement of the cutting blade 186. Adjusted.

  Preferably, in a state where the horizontal position of the moving portion 12a is adjusted, the booklet is moved in the horizontal direction so that the booklet comes into contact with the contact surface 182. Thus, the booklet does not slide with respect to the contact surface 182. Therefore, it is possible to prevent the occurrence of scratches and the like.

  Next, the press plate 188 is moved in the horizontal direction to press the booklet toward the contact surface 182, and in this state, the top and bottom cutting blade 186 is moved in the horizontal direction to perform cutting (FIG. 4B). Since the cut chips can fall in the vertical direction, the processing of the chips is easy.

  Next, the control unit 20 outputs a control signal to the positioning actuator 12, and the moving unit 12a of the positioning actuator 12 moves to the ground cutting unit 190 to perform the same processing. Since the processing is the same as that of the top side cutting unit 180, description thereof is omitted. In this way, the three sides can be cut. Since the positioning is performed by adjusting the position of the moving unit 12a based on the bookbinding information and the detection signal, it is not necessary to change the small edge cutting unit 16 and the top and bottom cutting unit 18, and it is easy to change the size of the booklet. Can respond.

  In the above example, all processing is performed by one positioning actuator 12, but the present invention is not limited to this. For example, it is possible to use two or more actuators for movement in the small edge cutting section 16, movement between the small edge cutting section 16 and the top and bottom cutting section 18, movement in the top cutting section 180 and the ground cutting section 190, In that case, the moving part of each actuator may not necessarily be movable in three dimensions. For example, the edge cutting section 16 may be movable only in the vertical and horizontal axes, and the top cutting section 180 and the ground cutting section 190 are movable only in the horizontal two axes. Alternatively, the movement between the fore edge cutting unit 16 and the top and bottom cutting unit 18 may be movable only in one horizontal direction. The switching of the positioning actuator 12 can be performed, for example, while the booklet is fixed between the press plate and the contact surface during cutting. As described above, each positioning actuator 12 sequentially processes the corresponding booklet, whereby the flow process can be performed. Since each process is performed based on bookbinding information and detection signals of booklets, even booklets of different sizes can be sequentially processed in the flow operation. Also, the position of the detection means can be set to an arbitrary position. Further, the detection means detects the back end face, and based on the detection signal, the moving unit 12a may be moved so that the fore edge cutting line S1 coincides with the vertical position of the reciprocating movement of the fore edge cutting blade 166. .

  In the above example, a three-way cutting machine is taken as an example of the cutting machine 10, but the present invention is not limited to this, and it is of course possible to configure as a small cutting machine including only the small cutting unit 16.
