Further, a first detection sensor 35 for detecting the stoppage of the belt conveyor 32 is mounted on the gantry or its vicinity, and based on the detection of the first detection sensor 35, the first shutter 13 of the rewinder 10 is released. It descends to open the carry-out port 12 of the rewinding machine 10. The first detection sensor 35 is not particularly limited, and examples thereof include a proximity switch, a photoelectric switch, a limit switch, and a visual sensor.

A second detection sensor 36 for detecting the packaging roll body 11 mounted on the flat belt 34 upstream of the belt conveyor 32 is mounted on or near the gantry of the belt conveyor 32, and the second detection sensor 36 is used for detection. Based on this, the belt conveyor 32 is driven to circulate the flat belt 34. The second detection sensor 36 is not particularly limited, but for example, a proximity switch, a photoelectric switch, a limit switch, a visual sensor, or the like is used. Further, resin guide plates 37 for sandwiching the flat belt 34 from the left-right direction are erected on both sides of the gantry, and these plurality of guide plates 37 carry the packaging roll body 11 mounted on the flat belt 34 in the transport direction. Guide the vehicle (from top to bottom in FIG. 1) while preventing it from falling.

The detector 38 is composed of, for example, a magnetic sensor or a visual sensor that contributes to the detection of the metal component 14, is installed in the center of the upper part of the stand 33, and faces the middle stream of the belt conveyor 32 from above via a transport space for passing the packaging roll body. It functions to inspect whether or not the metal component 14 is mixed between the wrap films 2 of the packaging roll body 11 conveyed by the belt conveyor 32.

When the detector 38 detects the metal part 14 in the packaging roll body 11, the packaging roll body 11 is conveyed downstream of the belt conveyor 32 and stopped, and the patrol light and the buzzer for notifying the abnormality operate respectively. The packaging roll 11 is re-inspected as defective. On the other hand, when the metal part 14 is not detected in the packaging roll body 11, the non-defective packaging roll body 11 is conveyed downstream of the belt conveyor 32 and temporarily stopped, and then the air cylinder 39 for changing the direction is moved. Drive.

The air cylinder 39 is made of, for example, a double-moving single rod cylinder having excellent stain resistance and low noise, is installed on the base 31 of the metal detector 30, and is located on the downstream side of the belt conveyor 32. When the detector 38 does not detect the metal part 14 in the packaging roll body 11, the air cylinder 39 projects the reciprocating piston rod 40 and uses the cushioning pad 41 at the tip thereof as the peripheral surface of the packaging roll body 11. The packaging roll body 11 is pressed from the downstream side of the belt conveyor 32 to the upstream side of the car toner 20 to carry it sideways.

In the above configuration, when the packaging roll body 11 is manufactured and inserted into the packaging box, the rewinding machine 10 first rotates to the standby paper tube 3 supplied from the raw film / paper tube feeder 1. The opposite wrap film 2 is rewound by a predetermined length to manufacture the packaging roll body 11, and the manufactured packaging roll body 11 is stopped at the carry-out port 12 closed by the first shutter 13. In this case, when the first detection sensor 35 of the metal detector 30 detects the stopped state of the belt conveyor 32, the first shutter 13 of the rewinding machine 10 is lowered based on the detection of the first detection sensor 35. The carry-out port 12 of the rewinding machine 10 is opened.

When the first shutter 13 is lowered to open the carry-out port 12 of the rewinding machine 10, one of the packaging rolls 11 is conveyed to the flat belt 34 upstream of the belt conveyor 32 of the metal detector 30 while rolling. The belt conveyor 32 is driven for the first time to circulate the flat belt 34 based on the detection of the second detection sensor 36, and is guided to the guide plate 37 by the circulation of the flat belt 34. , The belt conveyor 32 is vertically conveyed from the upstream to the downstream via the middle stream.

When passing through the middle stream of the belt conveyor 32, the packaging roll body 11 is inspected by the detector 38 for the presence or absence of metal component contamination, and when the detector 38 detects the metal component 14, it is regarded as a defective product downstream of the belt conveyor 32. The patrol light that stops and notifies the abnormality operates, and the buzzer notifies the abnormality and is re-inspected by the waiting worker. At this time, the second shutter 22 descends based on the detection result of the detector 38 to block the carry-in port 21 of the car toner 20, and it is effective that the defective packaging roll body 11 is erroneously carried into the car toner 20. To prevent.

On the other hand, when the detector 38 does not detect the metal part 14, the packaging roll body 11 is conveyed downstream from the middle stream of the belt conveyor 32 and temporarily stopped as a non-defective product, and the air cylinder 39 is driven. Then, the piston rod 40 at the reference position protrudes and its tip is pressed against the peripheral surface of the non-defective packaging roll body 11, and the packaging roll body 11 laterally enters the carry-in inlet 21 upstream of the cartner 20 from the downstream side of the belt conveyor 32. Be transferred. At this time, since the second shutter 22 rises to open the carry-in port 21 of the cartner 20, it does not hinder the transport of the non-defective packaging roll body 11.

The non-defective packaging roll body 11 conveyed upstream of the car toner 20 is centered by a centering mechanism, and then is pressed into a packaging box raised into an elongated square cylinder to be inserted and box-made. ..

According to the above configuration, the packaging roll body 11 is not conveyed and mounted on the operating belt conveyor 32, but the packaging roll body 11 is conveyed and mounted on the stopped belt conveyor 32. Therefore, the belt conveyor 32 Even if the packaging roll body 11 comes into contact with the stopped flat belt 34, scratches do not occur and the quality is not significantly deteriorated. In addition, the yield of non-defective products and the product rate can be greatly improved, and the inspection process by visual inspection can be significantly reduced.

Further, since the air cylinder 39 is used to change the transport direction of the packaging roll body 11, the output and the stroke can be easily calculated, and the power consumption can be suppressed. Further, since the flat belt 34 is made of urethane rubber instead of metal, it is possible to prevent erroneous detection of the detector 38 for the metal component 14.

Next, FIGS. 4 to 6 show a second embodiment of the present invention. In this case, the metal detector 30 has a rotatable sorting plate that contacts the packaging roll 11 on the belt conveyor 32. 42 is installed instead of the air cylinder 39, the distribution plate 42 is swung according to the detection result of the detector 38, and the packaging roll body 11 is discharged from the belt conveyor 32 to either the cartoner 20 or the outside of the system. I have to.

When 14 is detected, based on the drive of the drive motor, it swings in one direction and comes into contact with the defective packaging roll 11 stopped downstream of the belt conveyor 32, and the defective packaging roll 11 is brought into contact with the defective packaging roll 11. The anti-cartner is transferred and discharged to the outside of the transport direction system in the 20 direction. When transferring / discharging to the outside of the transport direction system, the patrol light and the buzzer for notifying the abnormality are not indispensable and can be omitted.

On the other hand, when the detector 38 does not detect the metal part 14 in the packaging roll body 11, a good packaging roll that swings in the other direction and stops downstream of the belt conveyor 32 based on the drive of the drive motor. It comes into contact with the body 11 and transfers and discharges the non-defective packaging roll body 11 in the upstream direction of the car toner 20. Since the other parts are the same as those in the above embodiment, the description thereof will be omitted.

In this embodiment as well, the same action and effect as those in the above embodiment can be expected, and the packaging roll body 11 is selectively discharged to either the cartner 20 or the outside of the transport direction system by the sorting action of the sorting plate 42. It is clear that the sorting work of the inspected good and bad packaging rolls 11 is really easy.
