The control unit 148 of the present embodiment is disposed inside the control panel 150 disposed on the front side of the main frame 2.

  Below, the effect | action of this embodiment which consists of a structure mentioned above is demonstrated.

  First, the processing operation of the packaging box B by the packaging and unpacking processing device 1 of the present embodiment will be described.

  In the processing of the packaging box B by the packaging and unpacking processing apparatus 1 of the present embodiment, the rectangular parallelepiped packaging box B is placed in the longitudinal direction in the front and back direction at the supply position SP of the drive roller conveyor 11 driven by the positioning unit 3. It is started by mounting or transferring to the direction. The supply of the packaging box B to the supply position is automatically performed, for example, from the former line. Then, the packaging box B supplied to the driving roller conveyor 11 abuts against the supply stopper 22 while moving on the way from the front to the rear toward the end of the conveyance and the movement is stopped. , The packaging box B is aligned (FIG. 5). The fact that the packaging box B has reached the supply stopper 22 is detected by the supply sensor 25.

  Next, when the supply sensor 25 detects the arrival of the packaging box B, the supply pusher cylinder 20 of the supply pusher 18 is driven to move the push plate 19 to the right. The pressing surface 19 a of the pressing plate 19 abuts on the left side surface of the packaging box B during the movement of the pressing plate 19 to the right. Then, by moving the push plate 19 further to the right, the packaging box B moves to the right, and the movement is stopped by pressing the right side surface of the packaging box B against the position reference surface 17 a of the positioning guide 17. Thereby, positioning of packaging box B which makes a right side of packaging box B conveyance standard is performed (Drawing 4).

  Subsequently, the positioning state of the packaging box B in the positioning unit 3 is held until there is a request, and if there is a request, the supply pusher cylinder 20 of the supply pusher 18 is driven to move the push plate 19 to the left The supply stopper cylinder 23 is driven to sink the upper end of the supply stopper 22 below the transport surface 11a, thereby allowing movement of the packing box B, and the packing box B is Send to the cutting unit 4. Then, when the packaging box B is fed to the first cutting unit 4, the supply stopper cylinder 23 is driven, and the supply stopper 22 is raised to return to the original state. Here, the request is a control command for driving the positioning unit 3 sent from the control unit 148, and the control command determines that the processing of the packaging box B becomes possible in the positioning unit 3 In the case where the control unit 148 determines that the packaging box B has been delivered from the first cutting unit 4, for example, it is delivered.

  Then, the packaging box B sent out from the positioning unit 3 transits to the cutting conveyance conveyor 30 driven by the first cutting unit 4, and the packaging box B joining to the cutting conveyance conveyor 30 moves from the front to the rear. When it moves to a preset position, the driving of the cutting conveyor 30 is temporarily stopped. Then, when the movement of the packaging box B is temporarily stopped due to the driving stop of the cutting conveyance conveyor 30, the pressing cylinder 56 is driven, the pressing roller 54 abuts on the upper surface of the packaging box B, and the upper surface of the packaging box B is By pressing from above, the packaging box B is prevented from rising from the transport surface of the cutting transport conveyor 30.

  Next, when the pressing roller 54 presses the upper surface of the packaging box B, the movable electric actuator 41 is driven to move the left belt conveyor 35 to the right. The movement amount is set in advance. Then, by moving the left side belt conveyor 35 to the right, the lower portions of both sides in the lateral direction of the packaging box B are nipped by the correction roller 44 from the lateral direction outside. Thereby, deformation such as swelling in the lateral direction on both sides of the packaging box B is corrected. The correction state of the packaging box B by the correction roller 44 is shown in FIG.

  Next, when the correction roller 44 pinches the lower portions of both sides in the lateral direction of the packaging box B from the outside in the lateral direction, the cutting conveyer 30 resumes driving and the conveyance of the packaging box B resumes. At this time, the transport of the packaging box B is forcibly transported by the cross bar 35 b provided on the cutting transport belt 35 a. The correction transport is performed in a state where the upper surface of the packaging box B is pressed from above by the pressing roller 54 and the lower portions of both sides in the lateral direction of the packaging box B are sandwiched from outside in the lateral direction by the correction roller 44. In addition, since the packaging box B is conveyed in a state in which the lower portions on both sides in the lateral direction are pinched from the outside in the lateral direction by the corrective roller 44, the correction of the packaging box B by the corrective roller 44 is continued along the longitudinal direction. It can be implemented. In addition, the forced conveyance state of the packaging box B by the crosspiece 35b is shown in FIG.

  Next, in the packaging box B, both long sides of the bottom surface located on both sides in the lateral direction are cut by the rotary blade 51 while being forcibly transported. At this time, the rotary blade 51 enters between the outer package BA and the inner package BB. In the long side of the bottom surface of the packaging box B, the upper surface of the packaging box B is pressed from above by the pressing roller 54, and the lower parts of both sides of the packaging box B in the lateral direction Since it is cut by the rotary blade 51 in the closed state, positional deviation of the approach position of the rotary blade 51 with respect to the packaging box B can be prevented, so that the rotary blade 51 can be prevented from contacting the contents W. The cutting state of the long side on the right side of the bottom surface of the packaging box B by the rotary blade 51 is shown in an exaggerated manner in FIG.

  Next, when the packaging box B passes the rotary blade 51 and moves to a preset position, the driving of the cutting conveyor 30 is once again stopped. Then, when the movement of the packaging box B is once again stopped by stopping the driving of the cutting conveyer 30 again, the movable electric actuator 41 is driven to move the left belt conveyor 35 to the left and return to the original position. At the same time, the correction state of the packaging box B by the correction roller 44 is released. At this time, since the position of the pressing roller 54 holding the front of the packaging box B does not change, the protrusion 54 a can prevent the packaging box B from moving leftward with the belt conveyor 35 on the left side. Then, when the left side belt conveyor 35 returns to the original position, the pressing cylinder 56 is driven to separate the pressing roller 54 from the upper surface of the packaging box B and return the pressing roller 54 to the original position.

  Subsequently, the temporary stop state of the cutting conveyor 30 in the first cutting unit 4 is held until there is a request, and if there is a request, the driving of the cutting conveyor 30 is restarted again to put the packaging box B in posture. Send to the change unit 5. Here, the request is a control command for driving the first cutting unit 4 sent from the control unit 148, and this control command is controlled when processing of the packaging box B becomes possible in the first cutting unit 4 If the unit 148 determines that, for example, the control unit 148 determines that the packaging box B has been sent out from the posture changing unit 5, the control unit 148 sends the package.

  Next, the packaging box B delivered from the first cutting unit 4 is transferred to the posture changing conveyance conveyor 60 driven by the posture changing unit 5, and the packaging box B transferred to the posture changing conveyance conveyor 60 is transferred While moving from the front to the rear toward the end, the transport direction leading surface (rear surface) abuts against the posture changing stopper 72, the movement is stopped, and the packaging box B is aligned. The attitude changing sensor 79 detects that the packaging box B has reached the attitude changing stopper 72. When the attitude change sensor 79 detects the arrival of the packaging box B, the drive of the attitude change conveying conveyor 60 is stopped, and the attitude change stopper cylinder 73 is driven to convey the upper end portion of the attitude change stopper 72 to the conveyance surface 60a. I will sink below.

  Next, when the upper end portion of the attitude changing stopper 72 is sunk below the conveyance surface 60a, the first cylinder 69 is driven to raise the upper surface of the box support plate 68a above the conveyance surface 60a, and the packaging box B is moved. It separates above conveyance side 60a. Subsequently, when the packaging box B is separated above the transport surface 60a, the second cylinder 70 is driven to horizontally rotate the box support plate 68a by 90 degrees, thereby changing the orientation of the packaging box B horizontally by 90 degrees, In the present embodiment, the longitudinal direction of the packaging box B is a lateral direction. Then, when the box support plate 68a is horizontally rotated by 90 degrees, the first cylinder 69 is driven to lower the box support plate 68a and sink the upper surface of the box support plate 68a below the transport surface 60a. Thus, the packaging box B is placed on the transport surface 60a while the box support plate 68a is moving downward.

  Next, when the packaging box B is placed on the transport surface 60a, the correction cylinder 77 is driven to move the correction body 76 in the lateral direction. During the movement of the correction body 76 to the left side, the correction surface 76a of the correction body 76 abuts on the right side surface of the packaging box B after changing the direction, and the packaging box B Move to the left. The movement amount is set in advance. Then, the displacement of the lateral right side surface of the packaging box B is corrected by the movement of the correction body 76 to the left. That is, before and after the posture change, the transport standard of the packaging box B is both on the right side in the lateral direction. The transport standard is linear in the longitudinal direction.

  Then, the stopped state of the posture changing conveyance conveyor 60 in the posture changing unit 5 is held until there is a request, and if there is a request, the driving of the posture changing conveyance conveyor 60 is resumed to cut the packaging box B into the second cutting unit Send to 6 At this time, the control unit 148 controls the conveyance of the packaging box B by the posture changing conveyance conveyor 60 to reversely convey one end forward and then move backward. As a result, it is possible to prevent erroneous detection by the posture change sensor 79. Here, the request is a control command for driving the posture changing unit 5 sent from the control unit 148, and it is assumed that this control command causes the processing of the packaging box B to be possible in the posture changing unit 5 and the control unit 148. Is determined, for example, when the control unit 148 determines that the packaging box B has been delivered from the second cutting unit 6.

  Next, the packaging box B delivered from the posture changing unit 5 is connected to the cutting conveyor 30 driven by the second cutting unit 6 and, similarly to the first cutting unit 4 described above, from the posture changing unit 5 While receiving the transported packaging box B and transporting it from the front to the rear, it cuts a pair of sides along the transport direction A of the bottom surface of the packaging box B in the middle of transport, in this embodiment the short side And send it back one by one. Thereby, four sides of the bottom surface of the packaging box B are cut and cut. In addition, since the operation | movement by the 2nd cutting part 6 is made the same as that of the 1st cutting part 4 mentioned above, it abbreviate | omits about the detailed description.

  Then, the temporary stopping state of the conveying conveyor 30 for cutting by the second cutting unit 6 is held until there is a request, and when there is a request, the driving of the conveying conveyor 30 for cutting is restarted again to take the packaging box B posture. Send to the change unit 5. Here, the request is a control command for driving the second cutting unit 6 sent from the control unit 148, and this control command is controlled when processing of the packaging box B becomes possible in the second cutting unit 6 When the unit 148 makes a determination, for example, it is sent out when the control unit 148 determines that the contents W have been sent out from the box removing unit 7.

  Next, the packaging box B delivered from the second cutting unit 6 is transferred to the box removing transport conveyor 81 driven by the box removing unit 7, and the packaging box B transferred to the box removing transport conveyor 81 is transferred While moving from the front to the rear toward the end of the case, the transport direction leading surface (rear surface) abuts against the box removing stopper 92, the movement is stopped, and the packaging box B is aligned. The fact that the packaging box B has reached the box removal stopper 92 is detected by the box removal sensor 115 of the box removal temporary stopping means 82. Then, when the box removal sensor 115 detects the arrival of the packaging box B, the vertical slider 107 is driven to lower the box body discharge means 84 to a preset height position. As a result, the packaging box B is disposed between the two gripping members 101. Further, the pad cylinder 96 is driven, and the suction pad 95 ascends and abuts on the bottom surface of the packaging box B.
