Description

  The present invention relates to a mixed fiber manufacturing apparatus for manufacturing a mixed fiber in which vegetable fibers such as bamboo fibers and heat-bonded fibers are mixed.

  In recent years, it has been considered to effectively utilize various properties such as deodorant, bactericidal and antibacterial properties of various plants such as bamboo, kenaf, and straw. For example, cotton-like bamboo cotton obtained by defibrating blue bamboo is mixed with heat-bonded fibers to form mixed fibers, and then heat-bonded fibers are heat-bonded to form bamboo cotton mixed sheets (patents) Reference 1).

  In producing this bamboo-cotton mixed sheet, it was provided with a defibrating drum having a large number of defibrating needles on the outer periphery, and a bamboo cotton supplying means and a heat-bonding fiber supplying means arranged on the outer periphery of the defibrating drum. Bamboo cotton while defibrating by using a manufacturing device to hook bamboo cotton supplied from bamboo cotton supply means and heat fusion fiber supplied from heat fusion fiber supply means with a defibration needle on the outer periphery of the defibration drum And a heat-sealable fiber are mixed to form a mixed fiber, and the mixed fiber is laminated to form a sheet, and then passed through a heat-sealable sheet to heat-seal the heat-sealable fiber.

  In the conventional manufacturing apparatus, there is a problem that it is difficult to uniformly mix bamboo cotton and heat-sealing fibers in the mixed fibers. That is, after the bamboo cotton supplied from the bamboo cotton supplying means is hooked by the defibrating needle on the outer periphery of the defibrating drum and then defibrated, the heat fusing fiber supplied from the heat fusing fiber supplying means by the defibrating needle Is hooked and defibrated to mix bamboo cotton and heat-sealing fibers.

  However, since bamboo cotton supplied from the bamboo cotton supply means is simply hanged by the defibrating needle on the outer periphery of the defibrating drum, it can be easily shredded into fine pieces when the defibrating needle is caught. It is necessary to finish as much as possible, and the pretreatment process of bamboo cotton requires man-hours and time, which is problematic in terms of work efficiency. Moreover, even if bamboo cotton pretreated to the extent that it can be finely defibrated with a defibration needle is used, the length of bamboo cotton is relatively long, and the length of the heat-sealing fiber becomes longer than that of bamboo cotton. Therefore, there is a defect that the bamboo cotton and the heat-sealing fiber are not evenly mixed and are hardly mixed uniformly and uneven mixing is caused.

  In view of such a conventional problem, the present invention can produce a mixed fiber by mixing a plurality of types of fibers, and can mix the plurality of types of fibers substantially uniformly, thereby producing a high-quality mixed fiber without mixing unevenness.

  The rotating shaft 29 may be directly driven by a drive motor without using the transmission mechanism 30. The support cylinder 33 is coupled to the flange 34 with a bolt or the like, but may be formed integrally with one of the flanges 34. The fastening means 36 includes a fastening bolt 43 that passes through the rotary disk 26 from one flange 34 and is inserted into the other flange 34, and a nut 44 that is screwed to the fastening bolt 43.

  As shown in FIG. 7, the rotating disks 26 have substantially the same shape, and the rotating disks 26 are fitted into the support cylinder 33 so that the positions of the rotating disks 26 are sequentially changed in the circumferential direction. Thus, as shown in FIG. 6, the crushing blades 14 are spirally arranged on the outer periphery of the rotating body 15. Incidentally, in this embodiment, by combining a large number of the rotating disks 26 having the same shape, the grinding blades of the three rotating disks 26 in the axial direction between the pitches P1 of the grinding blades 14 of one rotating disk 26 are combined. 14 are arranged at substantially equal intervals in the circumferential direction.

The movable roller 54 is disposed on the upper side of the fixed roller 53 so as to be movable in the perspective direction with respect to the fixed roller 53, and is urged toward the fixed roller 53 by an urging means (not shown). Accordingly, the first feeding means 51 feeds the rotary bamboo 15 to the rotating body 15 side with the rough bamboo fiber 4 sandwiched between the fixed roller 53 and the movable roller 54 at a pressure corresponding to the biasing means. Each feed roller 52 is driven by a drive motor (not shown) via a winding type or other transmission mechanism 32.

  As shown in FIGS. 1 and 2, the second supply means 17 is provided on the lower side in the rotational direction of the rotating body 15 with respect to the first supply means 16, and the heat fusion carried by the conveyance means (not shown).

  The second housing means 55 is disposed between the housing wall 57 disposed obliquely with respect to the rotating body 15 and the housing wall 57 below the housing wall 57 and between the housing wall 57 and the heat-sealing fiber 2. A feed belt 58 that forms a storage chamber, and the heat-sealable fiber 2 is fed to the second feed means 56 side by rotation of the feed belt 58. The feed belt 58 is wound around the guide roller 59 and feeds the heat-fusible fiber 2 in the second accommodation means 55 to the second feed means 56 side while being driven in the feed direction by the drive means (not shown). It is like that.

  The second feed means 56 has a pair of feed rollers 60 and 61 disposed on both sides in the rotational direction of the rotary body 15 and close to the outer circumference of the rotary body 15. A number of ridges in the direction are formed in the circumferential direction. The feed rollers 60 and 61 are fixed, but one may be fixed and the other may be movable.

  The first fixed blade 18 pulverizes the coarse bamboo fiber 4 supplied from the first supply means 16 with the pulverizing blade 14 of the rotating body 15, and the second fixed blade 19 is pulverized by the first fixed blade 18. The bamboo fiber 1 and the heat-sealing fiber 2 supplied from the second supply means 17 are pulverized between the pulverizing blade 14 of the rotating body 15. Each of the fixed blades 18 and 19 has a main body portion 63 and a plurality of blade portions 64 arranged in an arc shape in the circumferential direction on the rotating body 15 side of the main body portion 63 as shown in FIGS.

  The blade portions 64 of the fixed blades 18 and 19 are formed substantially parallel to the axial direction of the rotating body 15 so that the tips thereof are positioned on substantially the same circumference around the rotation shaft 29. The pitch P2 in the circumferential direction is approximately the same as the pitch P1 of the grinding blade 14 of the rotating body 15 or smaller than the pitch P1. Moreover, the height h of each blade part 64 is substantially the same, and the pitch P2 is sequentially reduced toward the lower side in the rotational direction.

  The rollers 53, 60, 61 of the feeding means 51, 56 are arranged close to the fixed blades 18, 19 in the circumferential direction. Of the plurality of blade portions 64 of each fixed blade 18, 19, the first blade portion 64 a on the upper side in the rotation direction of the rotating body 15 corresponds to a line segment connecting the centers of the rotating body 15 and the rollers 53, 60. It is arranged close to the lower side of the rotational direction.

  As shown in FIGS. 3, 5, and 6, the adjusting means 65 and 66 include a protruding portion 67 that protrudes outward from the left and right sides of the fixed blades 18 and 19 through the support member 28, and a lower portion of the protruding portion 67. A fixed receiving portion 68 fixed to the support member 28 on the side, a guide portion 69 fixed to the support member 28 and guiding the protruding portion 67 in the radial direction of the rotating body 15, and the protruding portion 67 and the fixed receiving portion 68. Adjusting bodies 70 and 71 such as wedges interposed therebetween, a protruding portion 67, a fixed receiving portion 68, and a fixture 72 such as a bolt and a nut for fastening and fixing the adjusting bodies 70 and 71 are provided.

  The adjusting bodies 70 and 71 have inclined surfaces 70a and 71a that are slidably in contact with each other and parallel surfaces 70b and 71b formed on the opposite side, and one of them is relatively slid in the inclination direction of the inclined surfaces 70a and 71a. By moving, the clearance between the fixed blades 18 and 19 and the crushing blade 14 of the rotating body 15 can be adjusted. In addition, although the through-hole for the fixing tools 72 is formed in the protrusion part 67, the fixed receiving part 68, and the adjustment bodies 70 and 71, the through-hole of one adjustment body 70 is a long hole shape.

  The lamination conveyor 22 is provided with an adsorption box 22a below the lamination section 21 on the upper surface side, and adsorbs and mixes the mixed fibers 7 supplied through the guide duct 20 onto the lamination section 21 by the adsorption action of the adsorption box 22a. Thus, a laminated sheet 9 is formed. The conveyor 23 is provided on the lower side of the laminated conveyor 22 at substantially the same height as the laminated portion 21 side. The transfer conveyor 25 is provided with a suction box 25 a on the upper side of the suction portion 24 so that the lower surface side suction portion 24 sucks the laminated sheet 9 on the lamination conveyor 22 and transfers it onto the transport conveyor 23. . The suction boxes 22a and 25a are connected to a negative pressure source.

  In the sheet body manufacturing apparatus having the above-described configuration, when the sheet body 3 in which the bamboo fiber 1 and the heat-sealing fiber 2 are mixed is manufactured, the bamboo fiber 1 and the heat-sealing fiber 2 are combined with the mixed fiber manufacturing apparatus 11. The mixed fiber 7 is pulverized and mixed to form a mixed fiber 7. The mixed fiber 7 is laminated in a sheet shape by a laminating device 12 to form a laminated sheet 9, and then the heat-fusible fiber 2 of the laminated sheet 9 is heat-fused by a heat-sealing device. It is made to be the sheet | seat body 3 which the bamboo fiber 1 was embraced by the heat sealing | fusion of the heat sealing | fusion fiber 2 by making it adhere.

  When the mixed fiber 7 is manufactured by the mixed fiber manufacturing apparatus 11, the rough bamboo fiber 4 obtained by crushing the bamboo and drying appropriately and the appropriate heat-sealing fiber 2 having heat-fusibility are used. The rough bamboo fiber 4 is supplied to the rotating body 15 side by the first supply means 16 on the upper side in the rotation direction, and the heat-sealed fiber 2 is supplied by the second supply means 17 on the lower side.

  When the first supply means 16 supplies the rough bamboo fibers 4 in the first storage means 50 to the rotating body 15 side by side by the first feeding means 51, the rough bamboo fibers 4 are pulverized by the rotating body 15 rotating at high speed. While being finely pulverized between 14 and the first fixed blade 18, it is sent to the lower side as the rotating body 15 rotates.

  When the coarse bamboo fiber 4 is supplied by the first supply means 16, the crude bamboo fiber 4 is sandwiched at a predetermined pressure by the fixed roller 53 and the movable roller 54 near the outer periphery of the rotating body 15. The rough bamboo fiber 4 can be reliably supplied to the rotating body 15 side. Further, since the first blade portion 64 a of the first fixed blade 18 is close to the lower side near the line connecting the centers of the rotating body 15 and the fixed roller 53, the first fixed blade 18 is sandwiched between the fixed roller 53 and the movable roller 54. In this state, the rough bamboo fiber 4 can be sheared by the first fixed blade 18 and the pulverizing blade 14.

  Furthermore, the pitch P2 between the blade portions 64 of the first fixed blade 18 is shorter than the pitch P1 of the pulverizing blade 14 of the rotating body 15, and the small blade portions 64 are continuously arranged in the circumferential direction. The bamboo fiber 1 that moves in the rotation direction of the rotary body 15 moves along the first fixed blade 18 by the centrifugal force of the rotary body 15, and the grinding blade 14 of the rotary body 15 has a plurality of blades of the first fixed blade 18. The bamboo fiber 1 can be finely pulverized every time the portion 64 is passed.

  On the other hand, when the heat-sealing fiber 2 is supplied to the rotating body 15 by the second feeding means 56 of the second housing means 55 in the second supply means 17, the heat-sealing fiber 2 and the first fixed blade 18 are supplied. The bamboo fiber 1 that has passed through is pulverized together between the pulverizing blade 14 and the second fixed blade 19 of the rotator 15 and is sent to the lower side as the rotator 15 rotates. Therefore, by crushing the heat-fusible fiber 2 and the bamboo fiber 1 between the second fixed blade 19 and the crushing blade 14 of the rotating body 15, the heat-fusible fiber 2 can be crushed short and at the same time the bamboo fiber 1 Can be pulverized again, so that the heat-sealing fiber 2 and the bamboo fiber 1 can be evenly and uniformly mixed.

  In this way, using the coarse bamboo fiber 4, the coarse bamboo fiber 4 is pulverized between the pulverizing blade 14 and the first fixed blade 18 of the rotating body 15 to obtain a fine bamboo fiber 1, and then the bamboo fiber 1. And the heat-fusible fiber 2 are mixed between the pulverizing blade 14 and the second fixed blade 19 of the rotating body 15 while being finely pulverized, so that the short crushed bamboo fiber 1 and the heat-fusible fiber 2 can be uniformly distributed. It is possible to mix substantially uniformly, and it is possible to easily and efficiently produce a high-quality mixed fiber 7 having no mixing unevenness. Therefore, the yield of the mixed fiber 7 is improved while using the rough bamboo fiber 4 with little pretreatment, and it is possible to efficiently produce a high-quality product at a low cost.

  Also in the second fixed blade 19, the pitch P <b> 2 between the blade portions 64 is shorter than the pitch P <b> 1 of the grinding blade 14 of the rotating body 15, and the small blade portions 64 are continuous in the circumferential direction. The bamboo fiber 1 and the heat-sealable fiber 2 that move in the rotation direction are moved along the second fixed blade 19 by the centrifugal force of the rotary body 15, and the rotary body as in the case of the first fixed blade 18. Each time the 15 crushing blades 14 pass through each of the plurality of blade portions 64 of the second fixed blade 19, the two fibers can be evenly and uniformly mixed while finely crushing the bamboo fibers 1. Incidentally, it is desirable that the bamboo fiber 1 and the heat-sealing fiber 2 are pulverized so as to form a short fiber cotton.

  The mixed fiber 7 of the bamboo fiber 1 and the heat-sealing fiber 2 is sent to the laminated portion 21 of the laminated conveyer 22 through the guide duct 20, and has a predetermined thickness on the laminated portion 21 while receiving the adsorption action of the adsorption box 22a. After being stacked and pressed by the pressing roller 20a, it is sucked by the suction portion 24 of the transfer conveyor 25 and transferred to the transfer conveyor 23, and is transferred to the heat fusion apparatus of the next process by the transfer conveyor 23. Go.

  The fixed blades 18 and 19 are fixed to the support member 28 so as to be adjustable in the radial direction of the rotating body 15 by adjusting means 65 and 66, and the fixed blades 18 and 19 and the rotating body 15 are adjusted by the adjusting means 65 and 66. Since the clearance between the grinding blade 14 can be adjusted, the bamboo fiber 1 and the heat-sealing fiber 2 of the mixed fiber 7 can be pulverized to a target length by appropriately adjusting the clearance.

  In addition, the rotating body 15 is formed by laminating and connecting a plurality of rotating disks 26 having a plurality of grinding blades 14 provided on the outer periphery in the circumferential direction. Compared with the case where the rotating body 15 is configured, it can be manufactured easily and inexpensively, and repair when a part of the crushing blades 14 is damaged can be easily and inexpensively performed. Further, since each pulverizing blade 14 is spirally arranged on the outer periphery of the rotating body 15, even if the blade portions 64 of the fixed blades 18 and 19 are provided in parallel to the axial direction, the coarse bamboo fibers 4 and the like are formed by the pulverizing blade 14. The impact during pulverization can be reduced, and the rotating body 15 can be smoothly rotated.

  FIG. 11 illustrates a second embodiment of the present invention. The fixed blades 18 and 19 of this embodiment have substantially the same pitch P2 in the circumferential direction of the blade portions 64 except for the first blade portion 64a. Even in the fixed blades 18 and 19 having such a configuration, the circumferential pitch P2 of the blade portions 64 is smaller than the pitch P1 of the pulverizing blades 14 of the rotating body 15, and therefore can be crushed in the same manner as in the first embodiment. .

  FIG. 12 illustrates a third embodiment of the present invention. The fixed blades 18 and 19 may be integrally formed over the entire length of the rotating body 15 in the axial direction. However, as shown in the figure, the fixed blade body 70 is made of a material having a predetermined plate thickness. A plurality of sheets may be stacked in the thickness direction (the axial direction of the rotating body 15) and fastened by fastening means such as bolts and nuts. In this case, the fixed blade body 70 may have substantially the same thickness as each rotating disk 26 of the rotating body 15, and one fixed blade body 70 is configured to have a thickness corresponding to a plurality of rotating disks 26. May be.

  As mentioned above, although each embodiment of this invention was explained in full detail, this invention is not limited to this embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, although the rough bamboo fiber 4 (bamboo fiber 1) was illustrated as a vegetable fiber in embodiment, things other than the bamboo fiber 1 may be used. Further, when the mixed fiber 7 is manufactured by mixing three or more types of fibers, a supply means may be provided for each type corresponding to each of the three or more types of fibers. In that case, multiple types of plant fibers may be used, and multiple types of chemical fibers may be used. Depending on the application of the mixed fiber 7, the chemical fiber may be other than the heat-sealing fiber 2.

  When the plant fiber is hard like the coarse bamboo fiber 4, it is desirable to arrange the first supply means 16 for supplying the coarse bamboo fiber 4 on the upper side in the rotational direction of the rotating body 15. In the case of a fiber material that is more easily pulverized than the heat-fusible fiber 2, the second supply means 17 may be arranged on the upper side. The number of the rotator 15 may be one, or two rotators 15 are continuously arranged in series so that the fiber flows from the upper side to the lower side, and supply means is provided corresponding to the rotator 15. May be.

  The supply means 16 and 17 should just be what can accommodate the rough bamboo fiber 4 and the heat sealing | fusion fiber 2 and can supply it to the rotary body 15 side by a fixed amount, and is not limited to embodiment. Further, the configuration of the rotating body 15 and the configurations of the fixed blades 18 and 19 are not limited to the embodiment. The feeding means 51 and 56 may be configured such that the feeding amount can be adjusted according to the ratio of the bamboo fiber 1 and the heat fusion fiber 2. For example, the rotation speed of the feed roller may be adjustable.

  The mixed fiber 7 obtained by pulverizing and mixing the vegetable fiber such as the bamboo fiber 1 and the heat fusion fiber 2 may be used in addition to the molding of the sheet body 3. Moreover, you may utilize when mixing chemical fibers other than the heat-fusion fiber 2 and plant fibers, such as the bamboo fiber 1. FIG.
