[Detailed Description of Control System 4]
The packaging device 1 is provided with a control system 4 as shown in FIG.

  The control system 4 includes a controller 5 that controls operations of the first blower 77 and the second blower 78. A carry-in sensor 14 that detects the box-making sheet Z is connected to the input side of the controller 5. On the other hand, a first blower 77 and a second blower 78 are connected to the output side.

  When the controller 5 receives a detection signal transmitted when the carry-in sensor 14 detects the box-making sheet Z, the controller 5 starts measuring time from the time of reception. Then, the controller 5 controls the first blower 77 to perform a standby operation (low speed operation) when a first predetermined time (first predetermined time) elapses from the reception of the detection signal, and the second predetermined time. When the (first predetermined time) has elapsed, the second blower 78 is controlled to be in a standby operation. In order to make each blower 77 and 78 stand by, for example, the rotational speed of each blower 77 and 78 is lowered by an inverter.

  The first predetermined time in the present embodiment is a time until the box-making sheet Z that has passed through the carry-in sensor 14 is delivered to the side opening / closing frame 31 by the suction unit 21 in the sheet take-out unit 20 in the normal conveyance state. Is set. Further, the second predetermined time is a period until the box making sheet Z that has passed through the carry-in sensor 14 is formed in a box shape by the upper suction portion 42 and the side suction portion 43 in the assembly portion 40 in the normal transport state. Set to time.

  By setting the first and second predetermined times in this way, the blowers 77 and 78 are not in standby operation when the box-making sheet Z is sucked by the suction portions 21, 42 and 43. . As a result, it is possible to avoid dropping the box-making sheet Z being conveyed or being assembled.

  Further, as described above, since the second predetermined time is longer than the first predetermined time, the controller 5 is arranged in the order in which the controller 5 is arranged from the upstream side of the box making unit 2, that is, the suction part 21, the upper suction part 42, and the side. The first and second blowers 77 and 78 are controlled in the order of the direction suction part 43. Thereby, it becomes possible to carry out the standby operation of the operations of the first and second blowers 77 and 78 at the timing when the box-making sheet Z is delivered to the downstream side. As a result, the power consumption can be more effectively suppressed.

  Here, the standby operation of the first blower 77 refers to a state in which the suction unit 21 in the sheet take-out unit 20 generates a weak suction force as compared with a suction force that can reliably suck the box-making sheet Z. The same applies to the second blower 78.

  The time measurement in the controller 5 is reset every time a detection signal is input from the carry-in sensor 14, and the time measurement is started again from the beginning.

  In the present embodiment, the controller 5 controls the blowers 77 and 78 so that the first and second blowers 77 and 78 are in a standby operation when the sheet-feeding sheet Z is not carried into the sheet supply unit 13. Can do. As a result, it is possible to suppress the power consumption due to the normal operation of the first and second blowers 77 and 78 at all times.

  Further, the controller 5 returns the first and second blowers 77 and 78 in the standby operation state to the normal operation state before the standby operation state by the above control. Specifically, when the controller 5 receives a detection signal from the carry-in sensor 14, it starts time measurement from the time of reception. Then, the controller 5 allows the first blower 77 to generate the negative pressure in the normal state when the third predetermined time has elapsed from the reception of the detection signal, that is, the suction unit in the sheet take-out unit 20. The return control is performed so that the box-making sheet Z adsorbed to 21 can be adsorbed reliably. Similarly, the controller 5 returns the second blower 78 when the fourth predetermined time has elapsed.

  The third predetermined time in this embodiment is set to a time until the box-making sheet Z that has passed through the carry-in sensor 14 is delivered to the suction unit 21 by the sheet supply unit 13. Further, the fourth predetermined time in the present embodiment is set to a time until the box-making sheet Z that has passed through the carry-in sensor 14 is delivered to the side opening / closing frame 31 by the suction portion 21.

  The third predetermined time may be set shorter than the time until the box-making sheet Z that has passed through the carry-in sensor 14 is delivered to the suction unit 21 by the sheet supply unit 13. When it takes time for the rotation to return to the suction force of a predetermined value or more, it is desirable to set it shorter than the third predetermined time. Also, the fourth predetermined time may be set shorter than the above-mentioned times, similarly to the third predetermined time.

  As a result, the first and second blowers 77 and 78 that are in standby operation can be automatically returned to the normal operation state. As a result, it is possible to avoid placing a burden on the user to return the first and second blowers 77 and 78 to the normal operation state.
