Then, the sachet continuous body 104 is fed by the initial feed, and each part stops at the start position (step S2). And the small bag continuous body 104 is set to the storage box 13 (step S3).

  Next, the start switch is pushed again (step S4). Thereafter, it is determined whether or not the reserve box 5b is empty (step S5). When it is determined that the reserve box 5b is empty (YES in Step S5), the reserve stop is executed (Step S42), and the small bag continuum 104 supplied from the filling machine filling the reserve box 5b is stored in the reserve box 5b. Supply (step S43) and return to step S5.

  When it is determined that the reserve box 5b is not empty (NO in step S5), a conveyor set time reverse process is performed (step S6).

  Then, it is determined whether or not the light emitted from the optical sensor 14c of the auxiliary reserve box 12 is blocked by the continuous bag 104 (step S8). When it is determined that the light emitted from the optical sensor 14c is not shielded by the sachet continuous body 104 (NO in step S8), the auxiliary feed device is activated (step S50).

  When it is determined that the light emitted from the optical sensor 14d is blocked by the continuous bag 104 (YES in step S8), the auxiliary feed device is stopped (step S49).

  When the auxiliary feed device is activated (step S 50) or when the auxiliary feed device is stopped (step S 49), the light emitted from the optical sensor 14 c of the auxiliary reserve box 12 is blocked by the sachet continuous body 104. It is determined whether or not it has been performed (step S9). When it is determined that the light emitted from the optical sensor 14c is not shielded by the sachet continuous body 104 (NO in step S9), the sachet continuous body folding apparatus 1 stops in error (step S15).

  When it is determined that the light emitted from the optical sensor 14c is blocked by the small bag continuous body 104 (YES in step S9), the side feed device 10 and the feeding device of the conveyor belt 24 are continuously operated (step S10). Then, it waits for a predetermined time (step S11).

  Next, the folding unit 4 starts folding the small bag continuum 104 into the storage box 13 (step S12). Then, it is determined whether or not the light irradiated by the optical sensor 14a of the reserve box 5a is blocked by the small bag continuous body 104 (step S13). When it is determined that the light emitted from the optical sensor 14a is not blocked by the sachet continuous body 104 (NO in step S13), the sachet continuous body folding apparatus 1 stops in error (step S15).

  When it is determined that the alarm is not stopped (NO in step S18), it is determined whether or not the inspection result of the image inspection apparatus 2 is acceptable (step S31). When it is determined that the inspection result is not acceptable (NO in step S31), a re-inspection process is performed (step S51).

  FIG. 8 is a flowchart showing the operation of the reinspection process. First, the conveyor (conveyance belt 24) is stopped (step S42). Then, the conveyor is reversed (step S43). Next, it is determined whether a predetermined number of small bags of the continuous small bag 104 have been sent (step S44). When it is determined that the predetermined number of sachets have not been sent (NO in step S44), the process returns to step S44.

  When it is determined that a predetermined number of sachets have been sent (YES in step S44), the conveyor is stopped (step S45). Then, the conveyor is rotated forward (step S46). Next, image measurement of the sachet of the sachet continuous body 104 is started by the image inspection apparatus 2 (step S47). Thereafter, the inspection result by the image inspection apparatus 2 is determined (step S48).

  If it is determined that the inspection result by the image inspection apparatus 2 is acceptable (YES in step S48), the reinspection process is terminated. When it is determined that the inspection result by the image inspection apparatus 2 is unacceptable (NO in step S48), the process proceeds to step S19.

  When the re-inspection process is completed, it is determined whether the number of small bags of the continuous bag 104 folded in the storage box 13 has reached the storage notice number (step S32). When it is determined that the storage advance notice number has not been reached (NO in step S32), the process returns to step S32. When it is determined that the storage advance notice number has been reached (YES in step S32), the end notice buzzer is sounded (step S33).

  Then, it is determined whether the number of sachets in the sachet continuous body 104 folded in the storage box 13 has reached the storage number (step S34). When it is determined that the number of stored items has not been reached (NO in step S34), when the filling machine is activated, a continuous bag of small bags is supplied from the filling machine to the reserve box 5b (step S43). When it is determined that the storage number has been reached (YES in step S34), the storage completion display buzzer is sounded (step S35). Then, the folding unit 4 stops folding (step S36).

  Next, behind this, the side feed device 10 and the image inspection device 2 are stopped (step S37).

  Then, it is determined whether or not the light irradiated by the optical sensor 14a of the reserve box 5a is blocked by the small bag continuous body 104 (step S13). When it is determined that the light emitted from the optical sensor 14a is not blocked by the sachet continuous body 104 (NO in step S13), the sachet continuous body folding apparatus 1 stops in error (step S15).

  When it is determined that the light irradiated by the optical sensor 14a is blocked by the continuous bag 104 (YES in step S13), is the light irradiated by the optical sensor 14b of the reserve box 5a blocked by the continuous bag 104? It is determined whether or not (step S14).

  When it is determined that the light emitted from the optical sensor 14b is shielded by the continuous bag 104 (YES in step S14), the side feed device 10 has a high degree of stagnation of the continuous bag 104 in the reserve box 5a. Decreases the supply speed of the continuous bag 104 to the reserve box 5a (step S92).

  When it is determined that the light emitted from the optical sensor 14b is not shielded by the continuous bag 104 (NO in step S14), the side feed device 10 is low because the continuous bag 104 is low in the reserve box 5a. Increases the supply speed of the continuous bag 104 to the reserve box 5a (step S91).

  When the side feed device 10 loosens the supply speed of the continuous bag 104 to the reserve box 5a (step S92) or when the side feed device 10 increases the supply speed of the continuous bag 104 to the reserve box 5a (Step S91), the control part 6 judges whether it is an alarm stop state (step S18). When it is determined that the alarm is stopped (YES in step S18), the control unit 6 sounds the alarm display buzzer (step S19).

  Next, when the reset key provided on the operation panel 16 is pressed (step S21), the processing after the alarm is released is performed (step S22), and the process returns to step S4.

  When it is determined that the alarm is not stopped (NO in step S18), it is determined whether the number of small bags of the continuous bag 104 folded in the storage box 13 has reached the storage number (step S34). When it is determined that the number of stored items has not been reached (NO in step S34), when the filling machine is activated, a continuous bag of small bags is supplied from the filling machine to the reserve box 5b (step S43). When it is determined that the storage number has been reached (YES in step S34), the storage completion display buzzer is sounded (step S35). Then, the drive duct 18 stops rising (step S93).

  Thereafter, the storage box 13 is switched to another storage box 13 (step S39). Next, the stop switch is pressed (step S40), the buzzer is stopped (step S41), and the process returns to step S2.
