Description

  The present invention relates to a dry seaweed inspection apparatus for inspecting the shape and foreign matter of dry seaweed carried out from a laver drying apparatus.

  The dried seaweed carried out from the seaweed drying device is inspected for shapes such as tears, perforations, and other foreign substances such as shells, insects or wood chips attached to the surface and inside by the dry seaweed inspection device of the sorting line. The rejected dry seaweed is sorted. The inspection uses a line image sensor or the like to discriminate rejected dry seaweed that does not satisfy a predetermined standard, and classifies the acceptable dry seaweed and the rejected dry seaweed. Passed dry seaweed is shipped after being subjected to a series of processes of bundling, alignment, folding, binding, and boxing. On the other hand, the categorized rejected dry seaweed is not discarded as it is, but is classified according to the inspection item. Shipped in two categories.

  As a foreign matter inspection device, for example, in Patent Document 1, as shown in FIG. 4 (a), dry nori is irradiated so as to irradiate a gap between guide plates 30a and 30b for guiding dry nori provided in a dry nori transport path. A light source 31 is disposed on one of the conveyance surfaces, and a line image sensor 32 that receives reflected light of light emitted from the light source 31 is provided in the same direction as the light source with respect to the conveyance surface, and the amount of light incident on the line image sensor 32 A foreign matter inspection apparatus provided with sorting means for detecting a change in the amount of light and generating a foreign matter mixing signal when the amount of light exceeds a set value and sorting the rejected dry seaweed with the shutter 33; It is disclosed.

Further, as an apparatus for inspecting the shape and foreign matter of dry seaweed, Patent Document 2 discloses that the light source 35 and dry seaweed are passed through the dry seaweed transport path with a transport conveyor for shape inspection, as shown in FIG. 4 (b). The optical means 36 for receiving the light, the optical means 38 for receiving the light transmitted through the dry nori and the light source 37 with the dry nori sandwiched between them are arranged for inspecting the foreign matter inside the dry nori, and further the foreign matter adhering to the surface of the dry nori A light source 40 for irradiating light on the surface of the dried laver adsorbed by the suction drum 39, an optical means 41 for receiving reflected light, and a suction drum 42 for inspecting foreign matter adhering to the back surface of the dried laver. A dry seaweed inspection apparatus is disclosed in which a light source 43 for irradiating light on the backside of the dried seaweed and an optical means 44 for receiving reflected light are arranged.
Japanese Examined Patent Publication No. 7-65973 Japanese Patent No. 3121593

  In the inspection apparatus described in Patent Document 1, since the light is irradiated to one gap portion of the guide plate, the light source for foreign matter inspection, the sensor, and the antireflection plate on the upper and lower surfaces of the dried seaweed cannot be arranged.

  Further, when dust or the like adheres to the antireflection plate or the guide plate, it becomes whitish, and there is a problem that it is confused with foreign matter by reflected light such as dust even without dry seaweed.

  In addition, paint paints of various dry seaweed production equipment arranged on the production line are often peeled off and incorporated into dry seaweed, but it is accepted as a pass product without judging paint paint debris as a foreign object. There was a problem with shipping. In addition, dry seaweed chips or the like may adhere to the light source, and the amount of light incident on the sensor may be reduced, preventing correct inspection.

  Moreover, in the inspection apparatus described in Patent Document 2, it is necessary to perform an inspection in a state in which dry nori is adsorbed by the suction drum portion. However, there is a problem that the structure is complicated and that the control of the adsorbing force of dry nori is difficult. Moreover, in order to arrange the suction drum portions at two locations, a large space is required.

  In addition, defective dry seaweed that is rejected by the inspection is not discarded as it is, but if the foreign matter is defective, it is repaired and the defective shape is shipped after being sorted according to the degree, but the defective dry seaweed is classified by inspection item. It was not efficient because it was troublesome because it was processed after checking the defects one by one.

  Therefore, the present invention provides a dry seaweed inspection apparatus that can accurately perform various inspections of dry seaweed and can efficiently perform post-treatment of dry seaweed that has failed the inspection.

  The present invention relates to a dry seaweed inspection apparatus in which a dry seaweed sorting part for separating dry seaweed according to the inspection result of the inspection part is connected to an inspection part for inspecting dry seaweed moving on a transport path, and the inspection part is a foreign object inside the dry seaweed. Internal foreign matter inspection means for inspecting the presence of foreign matter, upper surface foreign matter inspection means for inspecting the presence or absence of foreign matter on the top surface of dry laver, bottom surface foreign matter inspection means for inspecting the presence or absence of foreign matter on the bottom surface of dry laver, undried inspection means for inspecting dryness, A shape inspection means for inspecting, wherein the internal foreign matter inspection means is provided with a light source sandwiching the dried seaweed being transported and a light receiving sensor that receives light irradiated from the light source and transmitted through the dry seaweed, and the upper surface foreign matter inspection means is A light source for irradiating light on the upper surface of the dried laver that is conveyed on the first guide plate in the conveying path and a light receiving sensor for receiving reflected light of the light that is irradiated on the upper surface of the dried laver The lower surface foreign matter inspection means includes a light source for irradiating light from an oblique direction to the lower surface of the dry nori between the first guide plate and the second guide plate arranged at a distance from the first guide plate, A light receiving sensor for receiving reflected light of the light irradiated on the lower surface is disposed, and the shape inspection means is disposed with a light receiving sensor for receiving light passing through the light source, the dried seaweed outer shape and the hole across the dried seaweed being conveyed. It is characterized by being.

  An air jetting unit that blows off dust and laver on the surface of the light source is provided, and a color detection filter is provided on the irradiation surface of the light source of the upper surface foreign matter inspection means and the lower surface foreign matter inspection means, and the upper surface side of the dry seaweed is covered with a polarizing filter. In addition, an optical interference prevention plate for preventing the irradiation light of the light source of the upper surface foreign matter inspection means and the irradiation light of the light source of the lower surface foreign matter inspection means from interfering is provided.

  Moreover, the dry seaweed classification part includes means for classifying acceptable dry seaweed and unacceptable dry seaweed to classify the acceptable dry seaweed and unacceptable dry seaweed, and means for classifying the unacceptable dry seaweed classified by this means according to the inspection items of the inspection means. The inspection item classification means arranges containers for storing dry seaweed classified by inspection items above and below across the conveyance path.

  The present invention inspects the foreign matter on the upper surface with the inclined guide portion of the first guide plate, the foreign matter on the lower surface with the gap between the first guide plate and the second guide plate, and the optical interference prevention plate as the light source for upper surface foreign matter inspection. Since it is provided in the vicinity, air blows to the light source section, and filter attachment reduces the effects of insufficient light quantity and irregular reflection due to dust and other deposits, foreign matter on both sides of the dry seaweed can be inspected with high accuracy. Further, since it is not necessary to arrange a suction drum, the structure can be simple and compact.

  Moreover, since this invention is classified according to the inspection item in which the rejected dry seaweed was inspected, it is possible to save the trouble of confirming which trouble each time during processing such as reworking and to improve the efficiency of processing the rejected dry seaweed.

  The dry seaweed inspection apparatus of the present invention will be described with reference to the drawings.

  1 is a side view of a dry seaweed inspection apparatus according to the present invention, FIG. 2 is an enlarged view of an inspection section, and FIG. 3 is a cross-sectional view showing a state where a filter is attached to a light source.

  In FIG. 1, the dry seaweed inspection apparatus comprises an inspection part 1 and a dry seaweed sorting part 2 connected thereto.

  In order to transport dry seaweed to the inspection unit 1, the dry seaweed is brought between the conveyor 3, 4, the carry-in belt conveyor 3 that carries dry dry seaweed from the dry seaweed drying device to the dry seaweed inspection device, and the carry-out belt conveyor 4 that carries out the inspected dry seaweed. A feed roller 5a, 5b that feeds the paper and a first guide plate 6 that guides the dried seaweed 5c between the feed rollers 5a, 5b, and a second guide plate 7 that are spaced from the first guide plate 6 are disposed. The first guide plate 6 and the second guide plate 7 are inclined so that the dry seaweed carry-in side is inclined downward so that the tip is guided upward even if the approaching dry seaweed droops slightly.

  The guide plate has a smooth surface and is painted black so that light is not reflected. In addition, the inclined guide portion of the first guide plate 6 has substantially the same inclination angle as the irradiation direction of the upper surface foreign matter inspection light source 9a, so that dust or the like on the inclined guide portion is attached even when there is no dry seaweed. Not affected by kimono.

  As shown in FIG. 2, the inspection unit 1 includes an internal foreign matter inspection device 8 that inspects foreign matter inside the dry seaweed by transmission of light irradiated on the dry seaweed, and foreign matter on the top surface of the dry seaweed by reflection of light irradiated on the top surface of the dry seaweed. Top surface foreign matter inspection device 9 for inspecting the bottom surface of the dried seaweed, and bottom surface foreign matter inspection device 10 for inspecting the foreign matter on the bottom surface of the dry seaweed, shape inspection device for inspecting the shape of the dried seaweed by passing the light irradiated on the dry seaweed 11, Furthermore, the undried dry seaweed detection apparatus 12 is arrange | positioned. When dry seaweed is carried into the inspection unit 1 from the dry seaweed drying device and sensed, an identification number is given to the dry dried seaweed by a control device (not shown), and then the pass or fail inspection contents are stored for each identification number. Is done.

  The internal foreign matter inspection device 8 is disposed between the carry-in belt conveyor 3 and the feed roller 5, and includes a light source 8a sandwiching the transported dry laver, and a light receiving sensor 8b that receives light emitted from the light source 8a and transmitted through the dry laver. Be placed.

  The top surface foreign matter inspection apparatus 9 irradiates the light source 9a that irradiates light from an oblique direction to the position of the inclined guide portion of the first guide plate 6 on the top surface of the dry nori conveyed on the first guide plate 6, and the top surface of the dry nori A light receiving sensor 9b that receives the reflected light of the emitted light is disposed.

  The lower surface foreign matter inspection apparatus 10 includes a light source 10a that irradiates light on the lower surface of the dried seaweed conveyed between the first guide plate 6 and the second guide plate 7 from an oblique direction, and reflected light of the light irradiated on the lower surface of the dried seaweed. A light receiving sensor 10b for receiving light is disposed.

  In order to prevent the irradiation light of the light source 9a of the upper surface foreign matter inspection apparatus 9 and the irradiation light of the light source 10a of the lower surface foreign matter inspection device 10 from interfering with each other, an optical interference prevention plate 9c is disposed in the vicinity of the upper surface foreign matter inspection light source 9a.

  The shape inspection apparatus 11 is disposed between the feed roller 5b and the carry-out belt conveyor 4, and is disposed so that a light source 11a and a light receiving sensor 11b that receives light passing through the outer shape and the hole of the dried seaweed are opposed to each other with the dried seaweed being conveyed. The

  The undried inspection device 12 uses, for example, a known undried dry seaweed detection device (see, for example, Japanese Patent Publication No. 58-35672 and Japanese Utility Model Publication No. 63-18094) in which an electrode is disposed on an insulating roller.

  As the light sources 8a, 9a, 10a, and 11a of these inspection apparatuses, infrared LEDs and fluorescent lamps 14 that are parallel to the width of the dry seaweed and are slightly longer than this width are used. If dry seaweed waste or dust adheres to the light source, the inspection cannot be performed correctly. Therefore, low pressure air is constantly blown from the nozzle 13 to the light sources 8a, 9a, 10a, and 11a by a compressor. In addition, when normal light quantity does not reach the light receiving sensors 8b, 9b, 10b, and 11b, it is regarded as abnormal, and high pressure air is blown to the abnormal light source part for a short time so that no seaweed debris or dust is attached. Make inspections with high accuracy.

  In FIG. 3, the blue film 15 is superimposed on the slits of the light sources 9a and 10a of the foreign substance inspection devices 9 and 10, and the polarizing film 16 and the protective glass 17 are stacked thereon. You may enable it to detect the paint debris which peeled off and was drawn into dry seaweed as a foreign material. The polarizing film 16 is overlaid on the blue film 15 in order to suppress malfunction due to irregular reflection.

  A CCD camera is used for the light receiving sensors 8b, 9b, 10b, and 11b, and the shape of the dried seaweed and foreign matter are determined by image processing.

  In FIG. 1, the inspection unit 1 is provided with a dry seaweed sorting unit 2 that separates dry seaweed according to the inspection result of the inspection unit. The dry seaweed classification part 2 is composed of an acceptable dry seaweed rejecting dry seaweed sorting part that sorts the acceptable dry seaweed and unacceptable dry seaweed, and an inspection item classification part that subsequently sorts the rejected dry seaweed according to inspection items.

  In the acceptable dry seaweed classification part, a shutter 18 is provided on the dry seaweed entry side to classify the dry seaweed discharged from the carry-out belt conveyor 4 of the inspection unit 1 into an acceptable dry seaweed and an unacceptable dry seaweed. When the acceptable dry seaweed is discharged from the carry-out belt conveyor 4 of the inspection unit 1, the shutter 18 tilts upward and falls without being placed on the shutter 18, and when a predetermined number (for example, 10 sheets) accumulates, the shutter 18 is folded from the next alignment device. It is sequentially conveyed to the music device. When the rejected dry seaweed is discharged from the carry-out belt conveyor 4 of the inspection unit 1, the shutter 18 becomes horizontal by the information signal of the rejected dry seaweed from the inspection unit 1, and the rejected dry seaweed advances on the shutter 18 as it is. Then, it is transferred to the belt conveyor 19 and conveyed to the inspection item-specific section.

  In the classification section by inspection item following the passing dry seaweed rejection dry seaweed classification part, the rejected dry seaweed classified in the acceptable dry seaweed rejection dry seaweed classification part is divided into inspection items, i.e. We classify it into adherent dry seaweed, undried dry seaweed, poor shape (large) dry seaweed, and poor shape (small) dry seaweed.

  The inspection item-specific sorting section includes a shutter, a conveyor, and upper and lower sorting containers for transporting unacceptable dry seaweed of the corresponding inspection item to a designated sorting container. The shutters are inclined upward when transported to the lower sorting containers 20a, 20b, and 20c, and are held horizontally when passing through, and the upper sorting containers 22a, 22b, and 22c. The shutters 23a, 23b, and 23c are arranged so as to be inclined upward when being conveyed and held horizontally when being conveyed.

  The rejected dry seaweed conveyed to the upper sorting containers 22a, 22b, and 22c is guided obliquely upward by shutters 23a, 23b, and 23c that are inclined upward, sent between the feed rollers 24, and sent to the upper sorting containers 22a, 22a, 22c. It falls to 22b and 22c. Between the shutters 23a, 23b, 23c and the feed roller 24, a guide bar 25 is provided for guiding the rejected dry seaweed, and a guide bar 25 serving as a presser and a guide is provided so that the rejected dry seaweed does not jump upward. It has been. Each shutter is driven up and down by an information signal of rejected dry laver sent from the inspection result of the inspection unit.

  Next, operation | movement of the dry seaweed test | inspection apparatus of this invention is demonstrated.

  The inspection unit 1 sequentially inspects the internal foreign matter inspection device 8, the upper surface foreign matter inspection device 9, the lower surface foreign matter inspection device 10, the shape inspection device 11, and the undried dry laver detection device 12.

  In the internal foreign matter inspection device 8, light emitted from a light source (infrared LED) 8a disposed below the dry seaweed and transmitted is received by the camera 8b, and the presence or absence of foreign matter inside the dry seaweed is inspected.

  The upper surface foreign matter inspection apparatus 9 receives the reflected light from the light source 9a disposed above the dry seaweed and receives the reflected light with the camera 9b, and inspects the presence of foreign matter on the upper surface of the dry seaweed. Light reflected and reflected from the light source 10a disposed below is received by the camera 10b, and the presence or absence of foreign matter on the lower surface of the dry laver is inspected.

  Further, the undried dry laver detecting device 12 detects the undried dry laver, and the shape inspection device 11 continuously irradiates the light source 11a disposed below the dry laver and receives the light passing through the outer shape and the hole of the dry laver with the camera 10b. The shape and holes of the dried seaweed are then inspected.

  For the dry seaweed to be inspected, the control device stores the identification number and information on the contents of the inspection that passed or failed.

  The inspected dry seaweed discharged from the inspection unit 1 and brought into the rejected dry seaweed classification part 2 separates the acceptable dry seaweed from the unacceptable dry seaweed. Therefore, when the acceptable dry seaweed is brought in, the shutter 18 for the acceptable dry seaweed is used. The passed dry seaweed is dropped by inclining upward by the information signal. When a predetermined number of fallen acceptable dried seaweeds accumulate, they are aligned and conveyed to the next folding process. When the rejected dry seaweed is carried in, the shutter 18 is held horizontally by the information signal of the rejected dry seaweed, proceeds on the shutter 18 as it is, is transferred to the belt conveyor 19 and is transported to the next inspection item classification section.

  In the inspection item classification section where the rejected dry seaweed is brought in, among the rejected dry seaweeds, when the internal foreign matter dry seaweed comes, the shutter 23a for the internal foreign matter dry seaweed tilts upward and guides the internal foreign matter dry seaweed upward to cause the internal foreign matter It is conveyed to the sorting container 22a for dry seaweed. When an unacceptable dry seaweed other than the internal foreign matter dry seaweed comes, the shutter 23a is in a horizontal state, proceeds on the shutter as it is, and is transferred onto the belt conveyor.

  In the next upper surface foreign matter sorting shutter 21a, when the upper surface foreign matter dried laver comes, the shutter 21a is inclined upward and dropped into the upper surface foreign matter dried seaweed container 20a. When an unacceptable dry seaweed other than the top foreign matter dry seaweed comes, the shutter 21a is in a horizontal state, proceeds on the shutter 21a as it is, is transferred to the conveyor, and is transported to the next inspection item classification section.

  Similarly, when the lower foreign matter dry seaweed comes, the lower foreign matter dry seaweed shutter 23b is inclined upward to guide the lower foreign matter dry seaweed upward and transport it to the sorting container 22b for the lower foreign matter dry seaweed. The rejected dry seaweed other than the bottom foreign matter dry seaweed is placed in the horizontal state on the shutter 23b and transferred to the conveyor and conveyed to the next inspection item-specific section.

  In the next shutter 21b for undried dry seaweed, when undried dry seaweed comes, the shutter 21b is inclined upward and dropped into the container 20b for undried dry seaweed. When an unacceptable dry seaweed other than the undried dry seaweed comes, the shutter 21b is in a horizontal state, proceeds on the shutter 21b as it is, is transferred to the conveyor, and is conveyed to the next section for each inspection item.

  Next, when dry seaweed with a large defect such as a large tear comes, the shutter 23c for poor shape (large) dry seaweed is inclined upward and guided upward to be conveyed to the sorting container 22c for bad shape (large) dry seaweed. To do. When an unacceptable dry seaweed other than that for the shape defect (large) dry seaweed comes, the shutter 23c is in a horizontal state, proceeds on the shutter 23c as it is, is transferred to the conveyor, and is conveyed to the next inspection item-by-inspection section.

  When the shape defect (small) dry seaweed comes, the shutter 21c for the shape defect (small) dry seaweed is tilted upward and dropped into the container 20c for the shape defect (small) dry seaweed.

  In addition, when there is a plurality of pieces of failure information in one sheet of dry seaweed, priority judgment is performed by the control device. For example, an internal foreign object that is difficult to find can be classified as an internal foreign object failure regardless of other rejection information with the highest priority.

  In this way, the acceptable dry seaweed, the internal foreign matter-attached dry seaweed, the top foreign matter-attached dry seaweed, the bottom foreign matter-attached dry seaweed, the undried dry seaweed, the poor shape (large) dry seaweed, the poor shape (small) dry seaweed are classified, and the rejected dry seaweed classified according to the inspection item After removing from the container, it can be efficiently post-processed without checking and sorting out foreign matters.
