Description

  The present invention relates to an apparatus for manufacturing a packaging roll that is inserted into a packaging box after inspection of the packaging roll.

  A conventional packaging roll manufacturing apparatus is not shown, but is a rewinder that wraps a wrap film for food packaging around a paper tube supplied from an upstream raw paper / paper tube supply machine to form a packaging roll. A car toner which is made by inserting a packaging roll body transported from the re-rolling machine into a cylindrically raised packaging box, and a weight checker which measures the mass of the packaging box transported from the car toner The case has a predetermined layout in the manufacturing plant from the viewpoint of avoiding interference with other equipment by arranging a specified number of packaging boxes transported from this weight checker and depositing them into the outer packaging box. They are juxtaposed (see Patent Documents 1, 2 and 3).

  The product transport height of the raw fabric / paper tube feeder, the rewinder, and the car toner is not the same height, and the raw fabric / paper tube feeder is installed at the lowest, and the rewinder is installed second highest. The car toner is installed the highest. The rewinder rewinds the flexible wrap film of the original fabric in the original fabric / paper tube feeder into a paper tube by a predetermined length to produce a packaging roll body, and uses this produced packaging roll body as a downstream car toner. Transport

  By the way, in the packaging roll body, since the original wrap film is rewound by a predetermined length by the machine equipment of the re-winding machine, it is before being transported from the re-winding machine to the car toner from the viewpoint of ensuring the quality It is necessary to inspect whether metal parts etc. are mixed in the In view of this point, there has been proposed a method in which a metal detector is interposed between the re-feeder and the car toner, which automatically inspects whether or not metal parts are mixed in the packaging roll.

  Generally, a metal detector of this type is mounted on a belt conveyor that mounts on a belt a packaging roll that has been transported by being rolled from an upstream rewinder and that transports it to a downstream car toner and this belt conveyor. And a detector for detecting the presence or absence of metal parts in the packaged roll body. In the belt conveyor, an endless belt constantly circulates, and a packaging roll that has been rolled up is mounted on the belt and conveyed downstream.

By opening the port 21, the metal detector 30 and the car toner 20 are communicated. On the other hand, when the packaging roll 11 is not conveyed from the metal detector 30 to the upstream of the car toner 20, the packaging roll 11 is lowered to close the loading port 21 of the car toner 20, and the packaging roll 11 is temporarily stored. Further, on the upstream side of the car toner 20, a centering mechanism for the packaging roll 11 passing through the loading opening 21 is installed, and the packaging roll 11 centered by this centering mechanism is inserted into the packaging box from the open end through an air cylinder or the like. To be inserted.

  A weight checker (not shown) for measuring with high accuracy the mass of the packaging box containing the packaging roll body 11 is installed downstream of the cartner 20 at a position shifted via a short conveyor in a direction perpendicular to the transport direction of the car toner 20. Downstream and rearward of the weight checker, a caser (not shown) is provided for stacking a specified number of packaging boxes transferred from the weight checker and inserting the same into the outer case.

  As shown in FIG. 1 and FIG. 3, the metal detector 30 is a belt conveyor 32 which mounts the packaging roll body 11 conveyed from the outlet 12 of the rewinder 10 on the flat belt 34 and conveys it to the car toner 20. A detector 38 for detecting the presence or absence of the metal part 14 in the packaging roll 11 mounted on the flat belt 34 of the belt conveyor 32, and the detector 38 does not detect the metal part 14 in the packaging roll 11 , And an air cylinder 39 for pressing the packaging roll 11 from the belt conveyor 32 to the car toner 20.

  The metal detector 30 includes a base 31 having a substantially rectangular plane and installed between the rewinder 10 and the car toner 20. The belt conveyor 32 is horizontally installed on the base 31. A gate-shaped stand 33 is provided so as to straddle the vicinity of the substantially central portion of the belt conveyor 32, and a detector 38 facing the belt conveyor 32 is mounted on the top of the stand 33.

  The belt conveyor 32 is provided on a base 31 of the metal detector 30 and includes a rack extending in the vertical direction in FIG. 1. Drive rollers and driven rollers are rotatably supported at both ends of the rack. Between the drive roller and the driven roller, endless flat belts 34 on which the packaging roll 11 is mounted in the vertical direction are wound so as to be able to circulate, and the flat belts 34 contribute to hygiene and exchangeability, etc. It is molded of urethane rubber or the like.

  Although not shown, a drive motor for a drive roller, a rotatable carrier roller for a flat belt 34, a rotatable return roller, a rotatable tension pulley, and the like are disposed on the frame of the belt conveyor 32. In addition, a first detection sensor 35 for detecting a stop of the belt conveyor 32 is mounted at or near the gantry, and the first shutter 13 of the rewinder 10 is based on the detection of the first detection sensor 35. It descends to open the outlet 12 of the rewinder 10. The first detection sensor 35 is not particularly limited, and may be, for example, a proximity switch, a photoelectric switch, a limit switch, a visual sensor or the like.

  A second detection sensor 36 for detecting the packaging roll 11 mounted on the flat belt 34 upstream of the belt conveyor 32 is mounted at or near the base of the belt conveyor 32, for detecting the second detection sensor 36. 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 sandwiching the flat belt 34 in the lateral direction are erected on both sides of the gantry, and the direction of conveying the packaging roll 11 on which the plurality of guide plates 37 are mounted on the flat belt 34 is conveyed. It guides while preventing the drop (from the top to the bottom in FIG. 1).

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

  When the detector 38 detects the metal parts 14 in the packaging roll 11, the packaging roll 11 is conveyed downstream of the belt conveyor 32 and stopped, and the patrol light and the buzzer for notifying an abnormality operate. The packaging roll 11 is re-inspected as a defective product. On the other hand, when the metal parts 14 are not detected in the packaging roll 11, the non-defective packaging roll 11 is conveyed downstream of the belt conveyor 32 and temporarily stopped, and then the air cylinder 39 for changing the direction is changed. To drive.

  The air cylinder 39 is, for example, a double-acting single-rod cylinder or the like which is excellent in resistance to contamination and small in noise and is installed on the base 31 of the metal detector 30 and positioned downstream of the belt conveyor 32. When the detector 38 does not detect the metal part 14 in the packaging roll 11, the air cylinder 39 causes the reciprocating piston rod 40 to protrude and the buffer pad 41 at the tip end of the air cylinder 39 is a circumferential surface of the packaging roll 11. The package roll body 11 is pressed from the downstream side of the belt conveyor 32 to the upstream side of the car toner 20 so as to be conveyed laterally.

  In the above configuration, when the packaging roll 11 is manufactured and inserted into the packaging box, first, the rewinder 10 rotates to the paper tube 3 in the standby state supplied from the raw fabric / paper tube feeder 1. The opposite wrap film 2 is rewound by a predetermined length to produce a packaging roll 11, and the produced packaging roll 11 stops at the outlet 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 rewinder 10 is lowered based on the detection of the first detection sensor 35. Thus, the outlet 12 of the rewinder 10 is opened.

  When the first shutter 13 descends to open the outlet 12 of the rewinder 10, the packaging roll 11 is conveyed while being rolled by the flat belt 34 upstream of the belt conveyor 32 of the metal detector 30, and the second 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 by the guide plate 37 by the circulation of the flat belt 34. , And from the upstream of the belt conveyor 32 via the midstream to the downstream.

  When passing through the middle stream of the belt conveyor 32, the package roll body 11 is inspected by the detector 38 for the presence or absence of metal part contamination, and when the detector 38 detects the metal part 14, it is judged as a defective product downstream of the belt conveyor 32. While stopping and notifying the abnormality, the patrol light operates and the buzzer notifies the abnormality, and the worker who has been on standby re-examines the inspection. At this time, based on the detection result of the detector 38, the second shutter 22 descends to close the carry-in port 21 of the car toner 20, and it is effective that the defective packaging roll 11 is carried into the car toner 20 by mistake. To prevent.

  On the other hand, when the detector 38 does not detect the metal part 14, the packaging roll 11 is transported from the middle stream of the belt conveyor 32 to the downstream 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 end is in pressure contact with the peripheral surface of the non-defective package roll body 11, and the package roll body 11 extends laterally from the downstream of the belt conveyor 32 to the loading port 21 upstream of the car toner 20. Be transported. At this time, since the second shutter 22 ascends to open the carry-in port 21 of the car toner 20, the transport of the non-defective packaging roll 11 is not hindered.

  Thus, the non-defective package roll body 11 conveyed upstream of the car toner 20 is centered by the centering mechanism, and then pressed and inserted into the elongated rectangular tube-shaped packaging box to be made into a box .

  According to the above configuration, the packaging roll body 11 is transported and mounted on the stopped belt conveyor 32 instead of being transported and mounted on the operating belt conveyor 32. Even if the package roll body 11 comes into contact with the flat belt 34 which has stopped its movement energy, the abrasion does not occur and the quality is not significantly reduced. In addition, the yield of non-defective products and the improvement of the product rate can be greatly expected, and moreover, the inspection process by visual inspection can be significantly reduced.

  In addition, since the air cylinder 39 is used to change the transport direction of the packaging roll 11, calculation of output and stroke becomes easy, and power consumption can be suppressed. Furthermore, since the flat belt 34 is not made of metal but made of urethane rubber, false detection of the detector 38 for the metal part 14 can be prevented.

  Next, FIGS. 4 to 6 show a second embodiment of the present invention. In this case, the metal detector 30 is provided with a rotatable distributing plate which 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 car toner 20 or the outside. I have to.

  The distribution plate 42 is rotatably supported via a support shaft in a direction (left and right direction in FIGS. 5 and 6) orthogonal to the conveyance direction of the belt conveyor 32, and the detector 38 is a metal part in the packaging roll 11 When 14 is detected, based on the drive of the drive motor, it is swung in one direction to contact the defective packaging roll 11 stopped at the downstream of the belt conveyor 32, and the defective packaging roll 11 is It is transported and discharged out of the transport direction system in the direction of the anti-carter 20 direction. In the case of transport / discharge out of the transport direction system, the patrol light and the buzzer for notifying an abnormality are not essential 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, the non-defective packaging roll is swung in the other direction and stopped downstream of the belt conveyor 32 based on the drive of the drive motor. In contact with the body 11, the non-defective packaging roll 11 is transferred and discharged in the upstream direction of the car toner 20. The other parts are the same as those in the above embodiment, and thus the description thereof is omitted.

  Also in this embodiment, the same function and effect as the above embodiment can be expected, and furthermore, the packaging roll body 11 is selectively discharged to either the car toner 20 or out of the transport direction system by the sorting function of the sorting plate 42. It is obvious that the sorting operation of the inspected good and defective packaging roll bodies 11 is extremely easy.

  In addition, although the paper tube 3 was shown in the said embodiment, it is not limited to this at all, The core made of resin may be sufficient. Although the first shutter 13 is provided on the downstream side of the rewinder 10 so as to be able to open and close in the above embodiment, the first shutter 13 may be provided on the upstream side of the metal detector 30 so as to be able to open and close. Further, although the second shutter 22 is provided on the upstream side of the car toner 20 so as to be openable and closable in the above embodiment, the second shutter may be provided on the downstream side of the metal detector 30 so as to be openable and closable. Further, centering mechanisms may be respectively installed on the upper and downstream sides of the second shutter 22, and the packaging roll body 11 may be centered a plurality of times by the plurality of centering mechanisms.

  Moreover, although the presence or absence of the metal components 14 in the packaging roll body 11 was test | inspected in the said embodiment, it is not limited at all by this. For example, a visual sensor may be employed as the detector 38 to check the presence or absence of metal powder, or check the presence or absence of dust or a piece of paper in the paper tube 3. Further, the material of the flat belt 34 can be changed to polyurethane resin, polyolefin resin, silicone rubber, fluororubber or the like according to the material and use of the packaging roll 11.

  Further, a buffer material such as a sponge for preventing damage to the packaging roll 11 can be laminated and bonded to the contact surface of the guide plate 37 in contact with the packaging roll 11.
