Definitions

  • the invention relates to tobacco filter inspection apparatus.
  • a tobacco filter comprises a rod member formed of filter material and a paper web wrapping the rod member. Specifically, the filter rod is formed by winding the paper web on the rod member, sticking the overlapping portions of the paper web together with glue to form a filter rod continuous body, and cutting the filter rod continuous body into predetermined length pieces.
  • an inspection apparatus is used to inspect whether there are foreign matters (glue crumbs, for example) adhering to the glued site of the paper web.
  • the inspection apparatus comprises a filter supporting guide that supports the filter rod continuous body being transported and a sensor arranged above the filter rod continuous body being transported and directed to a glued site of the paper web.
  • a conventional filter supporting guide includes a U-shaped groove (hereinafter, also referred to as a U groove) as viewed in a perpendicular cross-section to the direction that the filter rod continuous body is transported.
  • the width of the U groove is not set according to the diameter of the filter rod but set greater than the maximum diameter of the filter rod having various diameter.
  • the filter rod continuous body being transported is supported by the filter supporting guide only at one point at the bottom of the U groove and therefore might meander while being transported. Also if the foreign matters, after dropping during the transportation of the filter rod continuous body, are accumulated in the lower portion of the filter supporting guide, there is a possibility that the filter rod continuous body comes into contact with the foreign matters and meanders while being transported.
  • the filter rod continuous body meanders while being transported the glued site of the paper web deviates from a focus position of the sensor, which decreases detection accuracy of the inspection apparatus on foreign matters.
  • a measurement device used in the tobacco processing industry for measuring strands is known.
  • Such a measurement device comprises a protection tube that transports a strand and strand guide devices arranged at the inlet and outlet of the protection tube and designed to guide the strand (see Patent Literature 1, for example).
  • a protection tube that transports a strand and strand guide devices arranged at the inlet and outlet of the protection tube and designed to guide the strand (see Patent Literature 1, for example).
  • three-jaw chucks are used as the strand guide devices, and a strand is radially supported at multiple points and transported within the protection tube.
  • a strand is radially supported at multiple points by means of three-jaw chucks as strand guide devices.
  • the strand is not supported at multiple points in the measurement range of the measurement device and therefore might move freely.
  • the strand has a smaller diameter than the protection tube, the strand is liable to meander while being transported within the protection tube.
  • the strand is liable to meander while being transported within the protection tube. Detection accuracy on foreign matters therefore cannot be improved by applying the measurement device of Patent Literature 1 to the aforementioned inspection apparatus.
  • the filter rod continuous body has the shape of a thin rod with a diameter of 8.2 mm or less. Such a thin filter rod is transported at a velocity of 500 meters or greater per minute and therefore might widely meander when making contact even with a minute foreign matter.
  • An object of the invention is to obtain a tobacco filter inspection apparatus with which it is possible to improve detection accuracy on foreign matters at a glued site of a paper web of a filter rod continuous body.
  • a first mode of the invention provides a tobacco filter inspection apparatus.
  • the tobacco filter inspection apparatus comprises a filter supporting guide configured to support a filter rod continuous body being transported, the filter rod continuous body being formed by winding a paper web on a rod member formed of filter material and sticking overlapping portions of the paper web together with glue, and a sensor arranged above the filter rod continuous body being transported along the filter supporting guide and directed to a glued site of the paper web.
  • the filter supporting guide includes at least two flat surfaces for supporting the filter rod continuous body as viewed in a perpendicular cross-section to a direction that the filter rod continuous body is transported.
  • the filter rod continuous body being transported is thus supported by the filter supporting guide at the at least two flat surfaces for supporting the filter rod continuous body, which restrains the filter rod continuous body from meandering during transportation. If foreign matters drop during the transportation of the filter rod continuous body, the foreign matters are accumulated on lower parts of the at least two flat surfaces, with which the filter rod continuous body does not come into contact. This also restrains the filter rod continuous body from meandering during transportation. It is therefore possible to improve detection accuracy on foreign matters at the glued site of the paper web of the filter rod continuous body.
  • the filter supporting guide is a groove having a V-like shape (hereinafter, also referred to as a V groove) as viewed in the perpendicular cross-section to the direction that the filter rod continuous body is transported.
  • the filter rod continuous body is thus supported by the filter supporting guide at two points in the V groove and therefore restrained from meandering while being transported. If foreign matters drop during the transportation of the filter rod continuous body, the foreign matters are accumulated in a lower portion of the V groove, with which the filter rod continuous body does not come into contact. This also restrains the filter rod continuous body from meandering during transportation. It is therefore possible to improve detection accuracy on foreign matters at the glued site of the paper web of the filter rod continuous body.
  • the tobacco filter inspection apparatus further comprises a drive mechanism that is capable of moving the filter supporting guide toward or away from the sensor. Since the drive mechanism moves the filter supporting guide relative to the sensor, the filter supporting guide can be applied to filter rods with various diameters without being exchanged according to filter rod diameters.
  • the filter supporting guide includes a first flat surface and a second flat surface. An angle formed between the first flat surface and second flat surface is 2 ⁇ .
  • the drive mechanism is capable of moving the filter supporting guide between a first position that is farthest to the sensor and a second position that is closest to the sensor. A distance between the first position and the second position is 1.4 ⁇ (1+1/sin ⁇ ) mm. This allows a conceivable range of filter rod diameter to be covered with a minimum motion amount, which makes it possible to minimize the drive mechanism.
  • the tobacco filter inspection apparatus further comprises a filter holding member arranged above the filter rod continuous body being transported along the filter supporting guide so as not to interfere with the sensor and configured to regulate a vertical displacement of the filter rod continuous body being transported. This restrains the glued site of the paper web from deviating from a focus position of the sensor and improves detection accuracy on foreign matters at the glued site of the paper web of the filter rod continuous body.
  • the senor is a reflective optical sensor. This makes it possible to detect whether there are foreign matters adhering to the glued site of the paper web by measuring the amount of light reflection. The sensor therefore can perform inspection in a non-contact manner without contacting the filter rod continuous body.
  • the senor In a seventh mode of the invention according to the six mode, the sensor outputs an abnormal signal to an external device when a light reflection amount at the glued site of the paper web exceeds a predetermined threshold value. Since the abnormal signal is outputted when the light reflection amount exceeds the predetermined threshold value, that is, when it is detected that foreign matters adhere to the glued site of the paper web, a filter rod manufacturing apparatus can be stopped.
  • a tobacco filter inspection apparatus corresponds to an inspection section in a filter rod manufacturing apparatus.
  • a filter rod intended by the invention has a maximum diameter of 8.2 mm, a minimum diameter of 5.4 mm, and a circularity of 95% or more but less than 100%, for example.
  • Fig. 1 is a configuration view of a filter rod manufacturing apparatus according to one embodiment of the invention.
  • the filter rod manufacturing apparatus 100 roughly includes a tow processing section 10, a forming section 20, a wrapping section 30, an inspection section 40, and a cutting section 50.
  • the tow processing section 10 comprises a package (bale) 11 containing filter material made, for example, of cellulose acetate fibers, that is, tow T.
  • a tow path 12 extends from the package 11.
  • a primary banding jet 13 Arranged in the tow path 12 in the order from the package 11 side are a primary banding jet 13, a guide roller 14, a pair of pretension rollers 15, a pair of blooming rollers 16, and a secondary banding jet 17.
  • the secondary banding jet 17 is positioned at the end of the tow path 12.
  • the primary banding jet 13 ejects compressed air from the package 11 side toward the tow T.
  • the ejected compressed air opens or breaks the tow T and moderately stretches creases (crimps) in the tow T.
  • the guide roller 14 directs a feeding direction of the tow T toward the pair of pretension rollers 15.
  • the tow T then passes between the pair of pretension rollers 15.
  • the pair of pretension rollers 15 holds the tow T subjected to fiber-opening processing and applies predetermined tension to the tow T in consort with the pair of blooming rollers 16, to thereby further stretch the creases in the tow T.
  • the pair of blooming rollers 16 splits the tow T subjected to the fiber-opening processing into a plurality of bundles and feeds these bundles to the second banding jet 17.
  • the secondary banding jet 17 ejects the compressed air toward the split bundle.
  • the compressed air opens the fibers of the split bundle.
  • the split bundle is accordingly broadened in a width direction of the tow path 12 to form a flat filter web WF.
  • the filter web WF is then delivered to the forming section 20.
  • the filter web WF delivered to the forming section 20 is transported toward a trumpet guide 21 and passes through the trumpet guide 21. At this point, the filter web WF is squeezed to have a rod-like shape by the trumpet guide 21 to be formed into a rod member WR. The width of the flat filter web WF is gradually reduced as the filter web WF is transported toward the trumpet guide 21. The rod member WR is thereafter delivered to the wrapping section 30.
  • the wrapping section 30 comprises an endless garniture tape 31.
  • the garniture tape 31 runs on a horizontal forming bed, not shown, in a direction that the rod member WR is transported.
  • a paper web WP is fed onto the garniture tape 31.
  • the paper web WP is guided from a paper roll through a reservoir and a spray gun 32 to the garniture tape 31.
  • the paper roll and the reservoir are not shown.
  • the spray gun 32 applies adhesive agent, or so-called rail paste, to the center of the paper web WP as viewed in the width direction of the paper web WP.
  • the rod member WR that is fed from the trumpet guide 21 is overlaid on the paper web WP at the inlet. At this point, the rod member WR and the paper web WP are bonded together through the rail paste.
  • the rod member WR and the paper web WP then run on the forming bed with the garniture tape 31 and pass through a tong 33, a wrapping former 34, a heater 35, and a cooler 36 in the order named.
  • the tong 33 further compresses the rod member WR through the garniture tape 31 and the paper web WP in consort with the forming bed.
  • the rod member WR is formed into a circle in cross-section, and the paper web WP and the garniture tape 31 are bent to have a U-like shape in cross-section.
  • a lower half portion of the rod member WR is covered with the paper web WP.
  • one side edge portion of the paper web WP is covered on one side of an upper half portion of the rod member WR with the garniture tape 31 intervening therebetween.
  • the spray gun, not shown, of the wrapping former 34 applies seam paste to the other side edge portion of the paper web WP.
  • the seam paste is dried when the filter rod continuous body RS formed in the wrapping former 34 passes through the heater 35.
  • the seam paste is cooled when the filter rod continuous body RS passes through the cooler 36.
  • the seam paste sticks out of overlapping portions of the paper web WP during the aforementioned process and adheres to the paper web WP as glue crumbs.
  • the inspection section 40 inspects the filter rod continuous body RS formed in the wrapping section 30 as to whether there are foreign matters (glue crumbs, for example) adhering to the glued site of the paper web WP, before the filter rod continuous body RS is cut by the cutting section 50 discussed below. A specific configuration of the inspection section 40 will be discussed later.
  • the cutting section 50 comprises a rotating knife 51.
  • the rotating knife 51 cuts the filter rod continuous body RS transported from the inspection section 40 into predetermined length pieces, to thereby form discrete filter rods FR.
  • Fig. 1 is a configuration view showing the details of an inspection section according to one embodiment of the invention.
  • Fig. 3 is a cross-section of the inspection section as viewed from an arrow 3-3 shown in Fig. 2 .
  • the inspection section 40 comprises a filter supporting guide 41, a sensor 42, a drive mechanism 43, and a brush (filter holding member) 44.
  • the filter supporting guide 41 is horizontally provided between the wrapping section 30 and the cutting section 50.
  • the filter supporting guide 41 supports the filter rod continuous body RS transported from the wrapping section 30 and passes the filter rod continuous body RS to the cutting section 50.
  • the sensor 42 is arranged above the filter rod continuous body RS transported along the filter supporting guide 41 and directed to a glued site WP1 of the paper web WP.
  • the sensor 42 is so arranged that a focus position thereof comes to the glued site WP1 of the paper web WP.
  • the sensor 42 does not necessarily have to be arranged immediately above the filter rod continuous body RS as long as the focus position comes to the glued site WP1 of the paper web WP.
  • the sensor 42 is preferably a reflective optical sensor. Amount of light reflection from the glued site WP1 of the paper web WP changes depending on the state of the glued site WP1. Whether foreign matters adhere to the glued site WP1 of the paper web WP therefore can be detected by measuring the amount of light reflection.
  • a FU-35FZ produced by Keyence Corporation
  • a reflective optical sensor is utilized as the sensor 42 to measure the amount of light reflection, it is possible to detect the presence of foreign matters adhering to the glued site WP1 of the paper web WP.
  • the inspection sensor 42 therefore can perform the inspection in a non-contact manner without contacting the filter rod continuous body RS.
  • the sensor 42 determines that foreign matters adhere to the glued site WP1 of the paper web WP when the amount of light reflection at the glued site WP1 of the paper web WP exceeds a predetermined threshold value, and may output an abnormal signal to an external device that controls the operation of the filter rod manufacturing apparatus 100. If the sensor 42 is configured this way, when the amount of light reflection exceeds the predetermined threshold value, that is, when it is detected that foreign matters adhere to the glued site WP1 of the paper web WP, the filter rod manufacturing apparatus 100 can be stopped.
  • the filter supporting guide 41 includes a V-shaped groove (V groove) 411 in a perpendicular cross-section to a direction that the filter rod continuous body RS is transported.
  • the transported filter rod continuous body RS is therefore supported by the filter supporting guide 41 at two points in the V groove 411, regardless of filter rod diameter. This restrains the filter rod continuous body RS from meandering during transportation.
  • the filter rod continuous body RS Since the filter rod continuous body RS is restrained from meandering while being transported as described, it is possible to improve detection accuracy on foreign matters at the glued site WP1 of the paper web WP of the filter rod continuous body RS in the inspection section 40.
  • the portions of the rod member WR and the paper web WP which are bonded together with the rail paste becomes a lower part of the filter rod continuous body RS during transportation, and the lower part of the filter rod continuous body RS does not interfere with the lower portion of the V groove 411. Therefore, even if excess rail paste overflows from the paper web WP to be accumulated in the lower portion of the V groove 411, this does not cause the filter rod continuous body RS to meander during transportation.
  • the filter supporting guide 41 is described as including the V-shaped groove (V groove) 411 as viewed in the perpendicular cross-section to the direction that the filter rod continuous body RS is transported.
  • the filter supporting guide does not necessarily have to be configured that way and may include at least two flat surfaces for supporting a filter rod continuous body.
  • the filter rod continuous body being transported is supported by the filter supporting guide on at least two flat surfaces for supporting the filter rod continuous body, regardless of filter rod diameter. This restrains the filter rod continuous body from meandering during transportation.
  • the foreign matters drop during the transportation of the filter rod continuous body, the foreign matters are accumulated at lower parts of the at least two flat surfaces, with which the filter rod continuous body does not come into contact. This also restrains the filter rod continuous body from meandering during transportation.
  • the drive mechanism 43 is configured to be capable of moving the filter supporting guide 41 toward or away from the sensor 42.
  • the drive mechanism 43 may comprise jackscrews or jack motors that are provided at both ends of the filter supporting guide 41 and configured to adjust the position (height) of the filter supporting guide 41 in relation to the sensor 42. Since the drive mechanism 43 moves the filter supporting guide 41 relative to the sensor 42, the filter supporting guide 41 can be applied to filter rods having various diameters without being exchanged according to filter rod diameter.
  • Fig. 4 is a schematic diagram for explaining motion amount of a drive mechanism according to one embodiment of the invention.
  • the left-side drawing shows a situation where the filter supporting guide 41 supports the filter rod continuous body RS having a conceivable maximum diameter of 8.2 mm and is located at a first position that is farthest to the sensor 42.
  • the right-side drawing shows a situation where the filter supporting guide 41 supports the filter rod continuous body RS having a conceivable minimum diameter of 5.4 mm and is located at a second position that is closest to the sensor 42.
  • the drive mechanism 43 is configured to be capable of moving the filter supporting guide 41 between the first position and the second position.
  • a first-to-second position motion amount X can be set as below.
  • the filter supporting guide 41 includes a first flat surface 412 and a second flat surface 413 which configure the V groove 411, and an angle formed between the first flat surface 412 and the second flat surface 413 is 2 ⁇ .
  • a distance X1 from the sensor 42 at the first position to the lowest portion of the V groove 411 is obtained by the following expression (1), where L is a distance from the sensor 42 to the glued site WP1 of the paper web WP, and r1 is radius of the filter rod continuous body RS.
  • X1 L + r1 + r1/sin ⁇
  • a distance X2 from the sensor 42 at the second position to the lowest portion of the V groove 411 is obtained by the following expression (2), where L is a distance from the sensor 42 to the glued site WP1 of the paper web WP, and r2 is radius of the filter rod continuous body RS.
  • X2 L + r2 + r2/sin ⁇
  • the first-to-second position motion amount X is therefore obtained by the following expression (3).
  • a filter rod intended by the invention has a maximum diameter (2r1) of 8.2 mm and a minimum diameter (2r2) of 5.4 mm. Accordingly, the motion amount X of the drive mechanism 43 can be expressed by 1.4 ⁇ (1+1/sin ⁇ ) mm. A conceivable range of filter rod diameter therefore can be covered with a minimum motion amount. This makes it possible to minimize the drive mechanism 43.
  • the brush 44 is arranged above the filter rod continuous body RS transported along the filter supporting guide 41 so as not to interfere with the sensor 42.
  • the brush 44 regulates a vertical displacement of the filter rod continuous body RS by coming into contact with the filter rod continuous body RS being transported. This restrains the glued site WP1 of the paper web WP from deviating from a focus position of the sensor 42 and improves detection accuracy on foreign matters at the glued site WP1 of the paper web WP of the filter rod continuous body RS.
  • the brush 44 may comprise one or more than three brushes 44. If the brush 44 is provided closer to the wrapping section 30 than to the sensor 42, the foreign matters adhering to the glued site WP1 of the paper web WP can be removed before inspection. If the brush 44 is provided immediately before the cutting section 50, the brush 44 holds the filter rod continuous body RS, which facilitates the cutting by the rotating knife 51.
  • the filter supporting guide 41 does not surround the sensor 42. Accordingly, even if there is a significant change in the outer shape of the filter rod continuous body RS or if the filter supporting guide 41 deviates from a proper position, a transportation path of the filter rod continuous body RS is not closed. Furthermore, there is space above the filter supporting guide 41, which makes it possible to remove the foreign matters accumulated in the lower portion of the V groove 411 without difficulty and therefore achieve good maintainability.
  • the filter rod continuous body RS is restrained from meandering while being transported. Therefore, as long as the sensor 42 is properly installed, and sensor application is properly set, it is possible to detect foreign matters (glue crumbs, for example) having a diameter of 0.5 mm or more when the filter rod continuous body RS runs at a transportation velocity of 600 meters per minute.
