  The present invention has been made in connection with the invention of the aforementioned Japanese Patent Application Laid-Open No. 2002-323453, and makes it possible to inspect the packaging state of a roll-shaped package more reliably and with high accuracy, and It is an object of the present invention to provide a packaging state inspection apparatus and inspection method for a roll-shaped package capable of efficiently performing the above.

In the packaging state inspection apparatus for a roll-shaped package according to the present invention, end packaging members having inclined portions that are inclined along the radial direction of the roll body are mounted on both end faces of the roll body, A packaging state inspection device for a roll-shaped packaging body in which a packaging sheet is wound so as to cover the peripheral portion of the inclined portion of the end packaging member,
Illumination means for irradiating illumination light to the inclined portion of the end packaging member mounted on the roll-shaped packaging body and the packaging sheet wound around the peripheral portion;
Imaging means for imaging the end surface of the roll-shaped package based on the reflected light reflected by the illumination light;
With
The imaging unit is arranged on an axis of the roll-shaped package, and the illumination unit is arranged in a peripheral portion of the imaging unit.

  Thus, by arranging the imaging means and the illuminating means, the reflected light incident on the imaging means after the illumination light reflected by the illuminating means is reflected, for example, by the inclined portion of the end wrapping member serving as the site to be inspected. The difference in brightness between the reflected light and the reflected light from the packaging sheet wound around the peripheral portion can be further increased. As a result, it becomes possible to clearly identify the image by the inclined portion of the end packaging member in the roll-shaped packaging body imaged based on this brightness difference and the image by the packaging sheet wound around the peripheral portion, The packaging state of the roll package can be inspected reliably and with high accuracy.

  In addition, the illumination light is irradiated to the inclined portion of the end packaging member to be inspected and the packaging sheet wound around the peripheral portion. For this reason, for example, since it becomes unnecessary to image while rotating a roll-shaped package, the inspection of the packaging state of a roll-shaped package can be performed efficiently.

In the method for inspecting the packaging state of a roll-shaped package according to the present invention, end roll packaging members having inclined portions that are inclined along the radial direction of the roll body are mounted on both end surfaces of the roll body, And a packaging state inspection method for a roll-shaped packaging body in which a packaging sheet is wound so as to cover the peripheral portion of the inclined portion of the end packaging member,
Using illumination means for illuminating illumination light, and imaging means for imaging the end face of the roll package,
The end wrapping member mounted on the roll-shaped package by the illuminating unit after the illumination unit is disposed on the periphery of the image-capturing unit and the image-capturing unit is disposed on the axis of the roll-shaped package. By illuminating the inclined sheet and the packaging sheet wrapped around the peripheral portion with illumination light, and then imaging with the imaging means based on the reflected light reflected by the illumination means by the illumination means The packaging state of the roll package is inspected.

  According to the method for inspecting the packaging state of a roll-shaped package according to the present invention, the illuminating means is arranged on the periphery of the imaging means, and the imaging means is arranged on the axis of the roll-shaped package. For this reason, in the reflected light which reflects the illumination light by the illumination means and enters the imaging means, for example, the reflected light by the inclined portion of the end packaging member which becomes the inspection site and the packaging sheet wound around the peripheral portion The difference in brightness due to the reflected light due to can be further increased. As a result, it becomes possible to clearly identify the image by the inclined portion of the end packaging member in the roll-shaped packaging body imaged based on this brightness difference and the image by the packaging sheet wound around the peripheral portion, The packaging state of the roll package can be inspected reliably and with high accuracy.

  In addition, since the end packaging member and the packaging sheet can be illuminated at the same time by the same illumination means, the facility can be simplified and the time required for the inspection can be shortened.

  In addition, the illumination light is irradiated to the inclined portion of the end packaging member to be inspected and the packaging sheet wound around the peripheral portion. For this reason, for example, since it becomes unnecessary to image while rotating a roll-shaped package, the inspection of the packaging state of a roll-shaped package can be performed efficiently.

  In this case, the roll-shaped packaging body is used in which the end portion of the packaging sheet wound around the peripheral portion of the end portion packaging member is separated from the inclined portion of the end portion packaging member. doing. Thereby, in the reflected light incident on the imaging means, the reflected light by the packaging sheet wound around the peripheral portion of the end packaging member is further attenuated. For example, the inclined portion of the end packaging member serving as the inspected portion The difference in brightness between the reflected light by and the reflected light by the packaging sheet can be further increased. As a result, it is possible to more clearly discriminate between the image by the inclined portion of the end packaging member and the image by the packaging sheet wound around the peripheral portion of the roll-shaped package imaged based on the difference in brightness. Thus, the packaging state of the roll package can be inspected more reliably and with high accuracy. In addition, the position of the said edge part can also be test | inspected based on the reflected light from at least one of the edge part and inclination part of a packaging sheet.

  Moreover, the said roll-shaped package body has applied the said roll-shaped package body formed by winding a elongate photosensitive material sheet | seat, and packaging with a light-shielding material. Thus, when a roll-shaped package composed of a photosensitive material sheet and a light-shielding material is applied, it is possible to reliably inspect the light-shielding state of the photosensitive material, which is preferable.

  According to the present invention, in the inspection of the packaging state in the roll-shaped package, the light and darkness due to the reflected light from the inclined portion of the end packaging member that becomes the inspection site and the reflected light from the packaging sheet wound around the peripheral portion. The difference can be made larger. As a result, it becomes possible to clearly identify the image by the inclined portion of the end packaging member in the roll-shaped packaging body imaged based on this brightness difference and the image by the packaging sheet wound around the peripheral portion, The packaging state of the roll package can be inspected reliably and with high accuracy.

  Further, since the illumination light is irradiated to the inclined portion of the end packaging member to be inspected and the packaging sheet wound around the peripheral portion, for example, imaging is performed while rotating the roll-shaped packaging body. This eliminates the need to perform inspection of the packaging state of the roll-shaped package.

  FIG. 1 is an exploded perspective view of a light-shielding photosensitive material roll 20 to which a roll-shaped package packaging state inspection apparatus and inspection method according to the present invention are applied.

  This light-shielding photosensitive material roll (roll-shaped package) 20 is manufactured in the following manner. That is, in the radial direction of the cap material 28a and the photosensitive material roll 22 which are inserted into the core 26 on both end surfaces of the photosensitive material roll (roll body) 22 in which the long photosensitive material sheet 24 is wound around the core 26. A light shielding member (end wrapping member) 28 having an inclined portion 28b that is inclined along the outer side from the both end surfaces is mounted. Subsequently, the light-shielding leader (packaging sheet) L is joined to the end 24a of the photosensitive material sheet 24 via the joining tape T1. The light-shielding reader L includes a light-shielding sheet F1 and light-shielding shrink films F2 and F3 provided individually on both sides of the light-shielding sheet F1. End stopper tapes T2 and T3 are attached to the front end of the light shielding sheet F1.

Next, the light-shielding shrink films F2 and F3 disposed on both end faces of the photosensitive material roll 22 are covered with the peripheral portion of the inclined portion 28b of the light-shielding member 28 while being heated, so that the light-shielding feeling shown in FIGS. The optical material roll 20 is obtained. In the vicinity of the end portion F1a of the light-shielding sheet F1 on the surface of the light-shielding photosensitive material roll 20, and at a predetermined position 29 between the end portion stop tapes T2 and T3, explanations such as handling and caution items are printed. .

  The light shielding member 28, the light shielding sheet F1, and the light shielding shrink films F2, F3 basically have a black color. On the other hand, the end stopper tapes T2 and T3 and the description have a white color.

Show.

  The light-shielding photosensitive material roll 20 inspected by the inspection machine 42 is transported by a transport conveyor 44 from an upstream manufacturing apparatus (not shown). At that time, the light-shielding photosensitive material roll 20 is transported on the pallets 46 of the transport conveyor 44 with the end stopper tapes T2 and T3 positioned at the top.

  An anti-slip member 46 a made of a rubber material or the like is provided at a portion of the pallet 46 that comes into contact with the light-shielding photosensitive material roll 20 in order to securely maintain the positioning state of the light-shielding photosensitive material roll 20.

In FIG. 4, reference numeral 48 indicates a vertically movable stopper for temporarily stopping and positioning the pallet 46 with respect to the inspection machine 42 on the transport conveyor 44.

  A lifting mechanism 47 that displaces the pallet 46 up and down is provided below the transport conveyor 44 in the inspection machine 42, and the lifting mechanism 47 is fixed to, for example, a lower part of a support base 49 that supports the pallet 46. A nut member (not shown), a ball screw into which the nut member is screwed, a motor for rotating the ball screw, and the like are provided.

  The inspection machine 42 is printed on the first inspection unit 40 that inspects the quality of the width W of the light-shielding shrink films F2 and F3, the presence / absence of the end stopper tapes T2 and T3, the application position, the application angle, and the predetermined position 29.

And a fourth inspection unit 54 for inspecting and the like.

  As shown in FIGS. 4 to 6, the first inspection unit 40 includes a pair of first imaging units (imaging means) disposed on both sides on the axis P of the light-shielding photosensitive material roll 20 placed on the pallet 46. 60a and 60b are provided. The first imaging units 60a and 60b are movable in the direction of the axis P in order to correspond to the type of light-shielding photosensitive material roll 20 depending on the width of the photosensitive material sheet 24 and the like.

  The first inspection unit 40 includes a pair of first illumination units (illuminating means) 62a and 62b that are formed in an annular shape and are arranged around the first imaging units 60a and 60b. The arrangement positions of the first illumination units 62a and 62b with respect to the first imaging units 60a and 60b are within a range in which the illumination light emitted from the first illumination units 62a and 62b does not directly enter the first imaging units 60a and 60b. Basically, it is movable.

  The first illumination parts 62a and 62b are light-shielding properties that are wound around the end faces of the light-shielding photosensitive material roll 20, that is, the inclined portions 28b of the light-shielding member 28 mounted on the light-shielding photosensitive material roll 20 and the peripheral portions of the inclined portions 28b. Irradiation light is irradiated to the shrink films F2 and F3. The first imaging units 60a and 60b are reflected by the reflected light reflected by the inclined portion 28b of the light shielding member 28 and the light shielding shrink films F2 and F3 among the reflected light reflected by the illumination light from the first illumination units 62a and 62b. The end face is imaged based on the difference in brightness with the reflected light.

  Specifically, as shown in FIG. 8, the radial direction of the inclined portion 28 b in the reflected light that is irradiated with illumination light from the first illumination portion 62 a (62 b) and enters the first imaging portion 60 a (60 b). It is preferable that the first illumination unit 62a (62b) and the first imaging unit 60a (60b) are arranged in a positional relationship such that the reflected light reflected by the substantially central portion of the light, that is, the regular reflection light Q1, becomes larger. On the other hand, the specularly reflected light Q2 from the end of the light-shielding shrink film F2 (F3) is reflected in a direction not incident on the first imaging unit 60a (60b), that is, in a direction further away from the first imaging unit 60a (60b). It is preferable.

  The reflected light reflected by the end portion of the light-shielding shrink film F2 (F3) is guided to the first imaging unit 60a (60b), while the reflected light reflected by the inclined portion 28b is guided to the first imaging unit 60a (60b). The positional relationship between the first illumination unit 62a (62b) and the first imaging unit 60a (60b) may be set so as to reflect in a direction not incident on the first imaging unit 60a (60b). Further, the first imaging unit 60a (60b) and the first illumination unit 62a (62b) are configured such that one can move back and forth with respect to the other, and the light reflected by the light-shielding shrink film F2 (F3) and the inclined unit 28b is reflected. The light receiving position may be adjusted.

  With this configuration, even when the light shielding member 28 and the light-shielding shrink film F2 (F3) have the same color, for example, the reflected light that is incident on the first imaging unit 60a (60b). Among them, the reflected light including the regular reflection light Q1 by the inclined portion 28b of the light shielding member 28 and the reflected light including the regular reflection light Q2 by the light-shielding shrink film F2 (F3) wound around the peripheral portion of the inclined portion 28b. The brightness difference can be increased. As a result, an image by the inclined portion 28b of the light shielding member 28 in the light shielding photosensitive material roll 20 imaged based on the difference in brightness and an image by the light shielding shrink film F2 (F3) wound around the peripheral portion of the inclined portion 28b. Can be clearly identified, and the packaging state of the light-shielding shrink film F2 (F3), that is, the quality of the width W of the light-shielding shrink film F2 (F3) can be reliably and accurately inspected.

  In addition, the first illumination part 62a (62b) formed in an annular shape is wound around the end face of the light-shielding photosensitive material roll 20 to be inspected, that is, the inclined part 28b of the light-shielding member 28 and the peripheral part of the inclined part 28b. The light-shielding shrink film F2 (F3) is irradiated with illumination light. For this reason, for example, since it is not necessary to perform imaging while rotating the light-shielding photosensitive material roll 20, it is possible to efficiently inspect the light-shielding photosensitive material roll 20.

  As shown in FIGS. 4 and 5, the second inspection unit 50 includes a pair of second imaging units 64 a and 64 b disposed above the light-shielding photosensitive material roll 20 placed on the pallet 46, and a flat plate shape. The light-shielding photosensitive material roll 20 is formed and provided with a pair of second illumination portions 66a and 66b disposed obliquely above the axis P direction. The second imaging units 64a and 64b and the second illumination units 66a and 66b are basically fixed.

  The second illuminators 66a and 66b illuminate the end stopper tapes T2 and T3 and the predetermined position 29 of the light-shielding photosensitive material roll 20 with illumination light. The second imaging units 64a and 64b print the reflected light reflected by the light shielding sheet F1, the end stopper tapes T2 and T3, and the predetermined position 29 among the reflected light reflected by the illumination light from the second illumination units 66a and 66b. The upper surface of the light-shielding photosensitive material roll 20 is imaged based on the brightness difference from the reflected light reflected by the explanatory text.

  In this case, the light shielding sheet F1 of the light shielding photosensitive material roll 20 basically has a black color, and the illumination light is irradiated to the light shielding sheet F1 obliquely from above. The light reflected by the light shielding sheet F1 is hardly incident on the second imaging units 64a and 64b. Accordingly, the second imaging units 64a and 64b can easily inspect the end stopper tapes T2 and T3 having white color or the presence of the explanatory text printed on the predetermined position 29, the pasting position, and the like. Is possible.

  As shown in FIGS. 4, 6, and 7, the third inspection unit 52 is disposed on both sides in the direction of the axis P of the light-shielding photosensitive material roll 20 placed on the pallet 46, and is a pair of so-called line sensors. The third detectors 68a and 68b are provided. The third detectors 68 a and 68 b detect the end face of the light-shielding photosensitive material roll 20, that is, the light-sensitive photosensitive material roll 20 in order to detect floating or peeling of the light-shielding shrink films F 2 and F 3 in the light-shielding photosensitive material roll 20. It has an optical axis along the radial direction. The third detectors 68a and 68b determine pass / fail according to whether or not the optical axis is within a specified range.

  The third detectors 68a and 68b are movable in the direction of the axis P in order to correspond to the type of the light-shielding photosensitive material roll 20 depending on the width of the photosensitive material sheet 24 and the like.

  As shown in FIGS. 4 and 7, the fourth inspection unit 54 is disposed above the light-shielding photosensitive material roll 20 placed on the pallet 46, and the light-shielding photosensitive material roll 20 is moved to the upper end by the elevating mechanism 47. A fourth imaging unit 72 and a fourth illuminating unit 74 are provided so as to be able to inspect floating and peeling of the end portion F1a of the light shielding sheet F1 when raised to the position. Further, the fourth imaging unit 72 and the fourth illumination unit 74 are arranged to face each other along the conveyance direction of the light-shielding photosensitive material roll 20.

  The 4th illumination part 74 irradiates illumination light centering on the uppermost part of the light-shielding photosensitive material roll 20 mounted in the pallet 46, ie, the edge part F1a of the light shielding sheet F1. The fourth imaging unit 72 images the illumination light from the fourth illumination unit 74, and determines whether the captured range is within a specified range.

  The first image capturing units 60a and 60b, the second image capturing units 64a and 64b, and the fourth image capturing unit 72 may be constituted by, for example, a CCD (charge coupled devise) camera. In addition, the first illumination units 62a and 62b, the second illumination units 66a and 66b, and the fourth illumination unit 74 are, for example, a plurality of LEDs (lights) that output red light that is less likely to affect the photosensitive material roll 22. emitting diodes) may be two-dimensionally arranged. Furthermore, the second illumination units 66a and 66b and the fourth illumination unit 74 may be configured by, for example, strobes that illuminate and extinguish in a short time.

  FIG. 9 is a block diagram of a control circuit of the inspection machine 42 configured as described above.

  In this control circuit, the programmable controller 102 performs operation control according to the diameter and width data of the light-shielding photosensitive material roll 20 supplied from the upper management computer 100. The programmable controller 102 includes a stopper 48 for stopping and transporting the pallet 46 on the transport conveyor 44 in the inspection machine 42, an elevating mechanism 47 for lifting and lowering the pallet 46 on which the light-shielding photosensitive material roll 20 is placed, and a light-shielding photosensitive device. The first imaging units 60a and 60b, the first illumination units 62a and 62b, the third detection units 68a and 68b, the fourth imaging unit 72, and the fourth illumination unit 74 that are displaced to correspond to the type of the material roll 20 are provided.

  In addition, the programmable controller 102 performs on / off control of the power sources 104a to 104e of the first illumination units 62a and 62b, the second illumination units 66a and 66b, and the fourth illumination unit 74. Furthermore, the programmable controller 102 processes the images imaged by the first imaging units 60a and 60b, the second imaging units 64a and 64b, and the fourth imaging unit 72, and displays the processing results on the monitor 106. 108d.

  The inspection machine 42 in which the first inspection unit 40 according to this embodiment is incorporated is basically configured as described above. Next, the operation thereof will be described with reference to the flowchart shown in FIG. .

  The first imaging units 60a and 60b, the first illumination units 62a and 62b, the third detection units 68a and 68b, the fourth imaging unit 72, and the fourth illumination unit 74 are positioned with respect to the light-shielding photosensitive material roll 20 from the management computer 100. This is performed in advance by the programmable controller 102 in accordance with the diameter and width data of the light-shielding photosensitive material roll 20 supplied.

  Then, the pallet 46 on which the light-shielding photosensitive material roll 20 is placed with the end F1a of the light-shielding sheet F1 positioned at the top and positioned in the direction of the axis P is transported to a predetermined position of the inspection machine 42 by the transport conveyor 44.

There is a large contrast between light and reflected light including regular reflected light Q2 by F3 (see FIG. 8). For this reason, the image captured by the first imaging unit 60a is brighter in the image of the inclined portion 28b of the light shielding member 28, while the image of the light-shielding shrink film F3 wound around the peripheral portion of the inclined portion 28b is darker. Therefore, the inclined portion 28b and the light-shielding shrink film F3 can be clearly identified.

  Then, after the image processing controller 108a processes the image picked up by the first image pickup unit 60a, the programmable controller 102 performs reception processing of image pickup completion by the first image pickup unit 60a from the image processing controller 108a, and the first lighting unit 62a is turned off.

  In step S4, the programmable controller 102 outputs a command to the power supply 104d to turn on the second illumination unit 66b.

In addition, when the 2nd illumination part 66b is comprised by the strobe, this light extinction process becomes unnecessary.

  In step S6, the programmable controller 102 outputs a command to the power supply 104c to light the second illumination unit 66a.

  Next, in step S7, the programmable controller 102 outputs an imaging command to the image processing controller 108c, and the second imaging unit 64b, based on the imaging command, the end stopper tape T3 of the light-shielding photosensitive material roll 20. An image of an area centered on is taken.

  Then, after the image processing controller 108c processes the image captured by the second imaging unit 64b, the programmable controller 102 performs the imaging completion reception process by the second imaging unit 64b from the image processing controller 108c, and the second illumination unit 66a is turned off. In addition, when the 2nd illumination part 66a is comprised by the strobe, this extinguishing process becomes unnecessary.

  In step S <b> 8, the programmable controller 102 outputs a command to the power supply 104 e to turn on the fourth illumination unit 74.

  Next, in step S9, the programmable controller 102 outputs an imaging command to the image processing controller 108d, and the fourth imaging unit 72, based on the imaging command, the uppermost region of the light-shielding photosensitive material roll 20, In particular, an image of an area centered on the end F1a of the light shielding sheet F1 is taken.

  Then, after the image processing controller 108d has processed the image captured by the fourth imaging unit 72, the programmable controller 102 performs reception processing of imaging completion by the fourth imaging unit 72 from the image processing controller 108d, and the fourth illumination unit 74 is turned off. In addition, when the 4th illumination part 74 is comprised by the strobe, this extinguishing process becomes unnecessary.

  In step S10, the programmable controller 102 outputs a command to the power supply 104b to light the first illumination unit 62b.

  Next, in step S11, the programmable controller 102 outputs an imaging command to the image processing controller 108a, and the first imaging unit 60b, based on the imaging command, the other end face of the light-shielding photosensitive material roll 20, that is, An image of an area formed by the inclined portion 28b of the light shielding member 28 and the light shielding shrink film F2 is taken.

  At that time, the reflected light including the regular reflection light Q1 by the inclined portion 28b of the light shielding member 28 among the reflected light by the illumination light from the first illumination portion 62b, and the light-shielding shrink film wound around the peripheral portion of the inclined portion 28b. There is a large contrast between light and reflected light including regular reflected light Q2 from F2 (see FIG. 8). Therefore, the image captured by the first imaging unit 60b is brighter in the image of the inclined portion 28b of the light shielding member 28, while the image of the light-shielding shrink film F2 wound around the peripheral portion of the inclined portion 28b is darker. Therefore, the inclined portion 28b and the light-shielding shrink film F2 can be clearly identified.

  Then, after the image processing controller 108a processes the image picked up by the first image pickup unit 60a, the programmable controller 102 performs reception processing of image pickup completion by the first image pickup unit 60b from the image processing controller 108a, and the first lighting unit 62b is turned off.

  In step S12, the programmable controller 102 detects the state of protrusions and the like from the both end surfaces of the light-shielding photosensitive material roll 20 based on the optical axes of the third detectors 68a and 68b. That is, the programmable controller 102 determines whether or not the light-blocking shrink films F2 and F3 are in particular within a specified allowable range based on the optical axis.

  Next, in step S <b> 13, the programmable controller 102 outputs a lowering command to the elevating mechanism 47, and the elevating mechanism 47 moves the light-shielding photosensitive material roll 20 together with the pallet 46 to the original position, that is, on the transport conveyor 44 by the stopper 48. Return to the position to be positioned.

  Next, in step S14, each of the image processing controllers 108a to 108d makes a pass / fail determination based on the captured images, and in step S15, outputs the results to the monitor 106 for display.

  Specifically, the image processing controller 108a determines whether or not the width W of the light-shielding shrink films F2 and F3 is within a prescribed allowable range based on the images captured by the first imaging units 60a and 60b. The image processing controller 108b performs the pass / fail judgment, and the image processing controller 108b checks whether the end stopper tape T2 is present, and the pasting position and the pasting angle are within a predetermined allowable range based on the image captured by the second imaging unit 64a. It is determined whether or not there is an image and whether or not there is an explanatory text printed at a predetermined position 29 is checked.

  In addition, the image processing controller 108c, based on the image captured by the second imaging unit 64b, checks whether or not the end stopper tape T3 is present, and whether the pasting position and the pasting angle are within a prescribed allowable range. The image processing controller 108d determines whether or not the light-blocking sheet F1 is lifted or peeled off within a prescribed allowable range based on the image captured by the fourth imaging unit 72. .

  When the steps S1 to S15 are completed with respect to a predetermined number of light-shielding photosensitive material rolls 20, the programmable controller 102 performs an inspection completion reception process and ends the packaging state inspection process by the inspection machine 42. To do.

  In this embodiment, the case where the inspection process for the light-shielding photosensitive material roll 20 is based on each of the above-described steps S1 to S15, but these steps S1 to S15 are the production of the light-shielding photosensitive material roll 20. You may change suitably by a condition, quality, etc.
