Problems to be Solved by the Invention

[0009] Therefore, the present invention aims to provide a removing device that can surely remove Mesophyll by using high-pressure jet water when extracting Fiber bundles extending in the longitudinal direction for 50 cm or more from natural plants after removing Mesophyll Mesophyll

Means for Solving the Problems

[0010] That is, the removing device of the present invention is configured to solve the above problems by Mesophyll including a placing member for placing A plant having leaves with fibrous bundles extending longitudinally within the leaf tissue. and a high-pressure jet device that jets high-pressure jet water onto the plant placed on the placing member to remove Mesophyll The system includes a mounting member that presses down on the plant placed on it from above, and a pressing member with a horizontal bar or mesh shape that moves around it using multiple rollers, and the mounting member and the pressing member are rotated, and the plant held between the mounting member and the pressing member is transported while the high-pressure jet water is sprayed to remove the leaf tissue.

[0011] With this configuration, when jetting high-pressure jet water onto the plant to remove Mesophyll Mesophyll is passed through to the lower side of the placing member, and Mesophyll on the front surface side and Mesophyll on the back surface side of the plant can be removed simultaneously Not only does this improve efficiency, but even when there are multiple leaves or pseudostems from which fiber bundles should be extracted, the plant can be transported sequentially while the leaf tissue is removed, allowing for continuous extraction of fiber bundles.

[0012] In addition, when using such a plant, Fiber bundles extending in the longitudinal direction a plant with cracks generated along the direction intersecting with Mesophyll is used.

[0013] With this configuration, since cracks are generated in Mesophyll in advance, high-pressure jet water can be jetted onto the cracked portion to remove <00001​​​​​​​​

[0014] According to the present invention, A plant with leaves that have veins extending along the long axis within the leaf tissue.

[Brief explanation of the drawing]

[Figure 2] A diagram showing a crack generation device in the same configuration. [Figure 3] Diagram showing a pineapple leaf with cracks. [Figure 4] Diagram showing a leaf tissue removal device in the second embodiment. [Figure 5] Diagram showing a leaf tissue removal device in the third embodiment. [Figure 6] Diagram showing a leaf tissue removal device in the third embodiment. [Modes for carrying out the invention]

[0016] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

[0017] In this embodiment Mesophyll Removal device 1 is, The leaf tissue contains fiber bundles that extend in the longitudinal direction. From the leaves and pseudostem of plants Mesophyll Remove, Fiber bundles extending in the longitudinal direction for 50 cm or moreThis device is designed to extract only certain parts of the plant, and as shown in Figure 1, it comprises a mounting member 2 on which the plant is placed, a pressing member 3 that presses down on the plant placed on the mounting member 2, and a high-pressure jet device 4 that sprays high-pressure water onto the plant sandwiched between the mounting member 2 and the pressing member 3. Characteristically, the mounting member 2 and the pressing member 3 are made of members with multiple openings, such as horizontal bars or mesh, and high-pressure water is sprayed from above onto the leaves of the plant sandwiched between the mounting member 2 and the pressing member 3, penetrating downwards to the surface side. Mesophyll Not only that, but also the back side Mesophyll This design also allows for the simultaneous removal of [unspecified element]. The details of this embodiment will be described below.

[0018] In this embodiment, Fiber bundles extending in the longitudinal direction for 50 cm or more Plants that possess multiple stems include fiber bundle In between, soft, which contains a lot of moisture Mesophyll Plants that are covered with this material are used, such as sisal (Asparagaceae), banana (Bananaaceae), Manila hemp (Cannabis sativa, Cannabaceae), flax, and ramie. In this embodiment, pineapple leaves will be used as an example.

[0019] The pineapple leaves used are those that have been cut near the base of the leaf, which would normally be discarded after the fruit for consumption has been harvested. Generally, during the pineapple harvest season from May to July, the leaves grow to a length of 50 to 100 cm and a thickness of about 2 mm. Therefore, these long pineapple leaves are used. The pineapple leaves used are fresh, containing more than 50% moisture after harvesting. When pineapple leaves with such a high moisture content are used, when the pineapple leaves are bent, Mesophyll The surface becomes prone to cracks 61 (see Figure 3), and when high-pressure water jets are applied to these cracks 61, MesophyllThis makes it easier to remove the pineapple leaves. On the other hand, when using pineapple leaves 6 that have been stored for a long time, immerse the pineapple leaves 6 in water for a certain period of time so that the moisture content becomes 50% or more. However, if the moisture content becomes too high, bend the leaves Mesophyll Since it is not possible to create cracks 61, the moisture content should be kept at around 50% to 70%.

[0020] To create cracks 61 in a pineapple leaf 6, a crack-generating device 5, as shown in Figures 1 and 2, is used. This crack-generating device 5 has rotating bodies 51 with convex bodies 52 arranged radially on their outer surfaces, positioned above and below each other, and is configured to rotate with the convex bodies 52 interlocked. The pineapple leaf 6 is then sandwiched between the rotating bodies 51, and the convex bodies 52 of the rotating bodies 51 alternately bend the pineapple leaf 6, causing cracks 61 to form on the surface of the pineapple leaf 6 as shown in Figure 3. Here, the pineapple leaf 6 is sandwiched and bent between the rotating bodies 51 positioned above and below, but it may also be possible to sandwich the pineapple leaf 6 between plate-like bodies with uneven surfaces and bend them strongly to create cracks 61 on the surface of the pineapple leaf 6. In addition to creating cracks 61 with such a crack-generating device 5, the pressure from above and below also causes cracks 61 to form. fiber bundle Prevent it from being cut.

[0021] In this way, the pineapple leaf 6, which has been split 61, Mesophyll Removal device 1 Mesophyll It was removed, and finally, Fiber bundles extending in the longitudinal direction for 50 cm or more Only the essential elements are extracted.

[0022] this Mesophyll In the first embodiment shown in Figure 1, the mounting member 2 of the removal device 1 is a horizontal bar or mesh-like member having multiple openings. When such a mounting member 2 is provided, the horizontal bar or mesh-like member may be fixed in place, but here, the mesh member is made of a flexible material and is moved around by multiple rollers 21 to transport the pineapple leaves 6.

[0023] On the other hand, above the mounting member 2, a pressing member 3 is provided to press down on and secure the pineapple leaves 6 placed on the mounting member 2. This pressing member 3 is also made of a mesh-like material and is rotated by multiple rollers 31 to press down on the pineapple leaves 6 with an elastic member such as a spring. In this example, the pressing is done with a spring, but the pineapple leaves 6 could also be pressed down by the weight of the pressing member 3.

[0024] Inside this revolving pressing member 3, a high-pressure jet device 4 is provided to spray high-pressure water. This high-pressure jet device 4 is designed to spray high-pressure water towards the surface of the pineapple leaves 6. Fiber bundles extending in the longitudinal direction for 50 cm or more Without cutting, Mesophyll The speed or water pressure is set to remove only the pineapple leaves 6. Specifically, the speed ejected from the high-pressure jet 4 is set to 3 m / s to 15 m / s (preferably 7 m / s to 12 m / s), or the water pressure is set to 2 MPa to 15 MPa. The spray shape from the high-pressure jet 4 is set to remove only the pineapple leaves 6. Fiber bundles extending in the longitudinal direction By setting it as a straight line perpendicular to the direction, this allows for a single, continuous movement along the shorter side of the pineapple leaf 6. Mesophyll This is designed to remove [unclear]. Alternatively, a cyclone nozzle or straight nozzle may be used to spray high-pressure water in all directions (forward, backward, left, and right). Furthermore, bubbles with a diameter of 1 μm to 500 μm may be mixed into this high-pressure water jet, and the high-pressure water jet may be sprayed intermittently at intervals of 0.1 to 0.5 seconds. The direction of this high-pressure water jet spray may be directly above the surface of the mounting member 2, but in this case, Mesophyll but fiber bundle It gets pushed to the side, inefficiently MesophyllIt is not possible to remove it. Therefore, high-pressure water jets are sprayed from above, diagonally downward towards the upstream side in the conveying direction. This directs the high-pressure water jets onto the cracks 61 created by the crack generating device 5, and gradually from there Mesophyll This allows for the removal of material by scraping it off. Furthermore, when high-pressure water jets are used, there is a possibility that the mounting member 2 may bend due to the water pressure. Therefore, a fixing member (not shown) that allows water to pass through is provided below the mounting member 2. Teo Also, ensure that the mounting member 2 does not bend.

[0025] Furthermore, an air jet (not shown) is provided on the downstream side of the mounting member 2 in the transport direction. fiber bundle This process blows away any moisture that has accumulated between the layers and also helps to loosen any fibers that have become lodged in the gaps between the horizontal bars or mesh.

[0026] <Second Embodiment>

[0027] In the first embodiment described above, the mounting member 2 was made of a member having multiple openings, such as a mesh, but a configuration as shown in Figure 4 can also be used.

[0028] This mounting member 2a includes a linear member 22 made of wires or pipes arranged parallel to a plane, and a cylindrical rotating member 23 whose outer surface is substantially aligned with the plane of the linear member 22. Multiple such rotating members 23 are provided along the conveying direction, and each is rotated in the same direction.

[0029] Each rotating member 23 has multiple grooves 23a along its outer surface, thereby Mesophyll Removed fiber bundle The material is designed to fit between the grooves, preventing it from getting tangled and allowing it to be transported.

[0030] On the other hand, the pressing member 3 is composed of multiple linear members 32 (shown as dashed lines in Figure 4), such as wires or pipes, and these members are arranged in a circular fashion, similar to the first embodiment. Although linear members 32 are used here, mesh-like members may also be used. The pineapple leaves 6 are then placed between these mounting members 2a and pressing members 3a, and the pineapple leaves 6 are brought into contact with the rotating member 23 for transport.

[0031] The high-pressure jet device 4, similar to the first embodiment, is positioned between the circulating pressing members 3a and directs the high-pressure jet water diagonally toward the surface of the pineapple leaf 6, both sides Mesophyll It is designed to be stripped away. Mesophyll It falls downward through the gaps between the linear member 22 and the rotating member 23 that constitute the mounting member 2a.

[0032] <Third Embodiment>

[0033] Alternatively, the configuration shown in Figure 5 can also be used. Mesophyll The removal device 1b has a cylindrical structure for the mounting member 2b and the pressing member 3b, with their outer surfaces made of mesh, wire, pipe, etc. A high-pressure jet 4 is installed inside the cylindrical pressing member 3b to spray high-pressure water onto the pineapple leaves 6 sandwiched between the mounting member 2b and the pressing member 3b, causing the water to penetrate the pressing member 3b and the mounting member 2b.

[0034] Furthermore, when the mounting member 2b and pressing member 3b are constructed from cylindrical members in this manner, the outer surface member may be made of a flexible member, as shown in Figure 6, so that the pressing force can be changed according to the thickness of the pineapple leaves 6. Elastically deformable curved spokes may be provided between the inner bearing and the outer surface member, so that the joint surfaces of the cylindrical mounting member 2b and the pressing member 3b are in surface contact.

[0035] Next, it is configured as follows Mesophyll The operation of removal device 1 will now be explained.

[0036] First, as a premise, we assume that cracks 61 have been generated on the surface of the pineapple leaf 6 by the crack generating device 5, and using the pineapple leaf 6 with the cracks 61 thus formed Mesophyll This section explains how to remove it.

[0037] From 6 pineapple leaves Mesophyll When removing the pineapple leaves 6, the pineapple leaves 6 are placed between the circulating mounting members 2 (2a, 2b) and the pressing members 3 (3a, 3b). Fiber bundles extending in the longitudinal direction The device is positioned to align with the direction of transport, and the pineapple leaves 6 are inserted into it for transport.

[0038] Then, the pineapple leaves 6, which are sandwiched between the mounting members 2 (2a, 2b) and the pressing members 3 (3a, 3b), are transported along the longitudinal direction by the drive of the rollers.

[0039] Then, high-pressure water is sprayed from the high-pressure jet device 4 located on the upper side toward the surface of the pineapple leaves 6. At this time, since the pineapple leaves 6 are fixed by the pressing members 3 (3a, 3b), the pineapple leaves 6 do not move around due to the water pressure, and the high-pressure water can be applied stably.

[0040] The high-pressure jet of water sprayed in this manner hits the cracks 61 formed on the surface of the pineapple leaf 6, scraping them off. Mesophyll Remove them.

[0041] Then, a high-pressure jet of water is passed through from the underside of the pineapple leaf 6 to below the mounting member 2 (2a, 2b), thereby cleaning the underside of the pineapple leaf 6. Mesophyll At the same time, we're also making sure that we can eliminate unnecessary elements.

[0042] Thus, according to the above embodiment, Pineapple leaves 6, each having fibrous bundles extending longitudinally within the leaf tissue.A mounting member 2 (2a, 2b) on which the pineapple leaves 6 are placed is used to spray high-pressure water jets onto the pineapple leaves 6 placed on the mounting member 2 (2a, 2b). Mesophyll A high-pressure jet device 4 to remove, The device comprises a mounting member 2 (2a, 2b) and a mounting member 3 (3a, 3b) that rotates around a pineapple leaf 6 placed on the mounting member 2 (2a, 2b) and press members 3 (3a, 3b) from above, and the high-pressure jet water is sprayed while the mounting member 2 (2a, 2b) and press members 3 (3a, 3b) are rotated and the pineapple leaf 6 held between the mounting member 2 (2a, 2b) and press members 3 (3a, 3b) is transported. Now that it's configured, spray high-pressure water jets onto the pineapple leaves 6. Mesophyll When scraping it off, the high-pressure jet water and Mesophyll It can be passed through to the lower side of the mounting member 2 (2a, 2b), and the surface side of the pineapple leaf 6 Mesophyll and the back side Mesophyll This makes it possible to remove both simultaneously.

[0043] The present invention is not limited to the embodiments described above and can be implemented in various ways.

[0044] For example, in the above embodiment, the high-pressure jet water was applied at an angle, but multiple high-pressure jets 4 could be provided, and the spray angle of each could be changed to apply the high-pressure jet water. By changing the spray angle in this way, the high-pressure jet water can be applied from various directions to areas that are difficult to reach, such as the contact area between the pressing member 3 (3a, 3b) and the pineapple leaf 6. Mesophyll This will allow us to remove it.

[0045] Furthermore, in the above embodiment, the mounting members 2 (2a, 2b) and pressing members 3 (3a, 3b) were made to rotate, but the high-pressure jet device 4 side was moved in the front-rear direction, Mesophyll You can also try removing them.

[0046] Furthermore, in the above embodiment, high-pressure water jets are sprayed from above, but when high-pressure water jets are sprayed inside the device, there is a possibility of splashing off the walls, etc. Therefore, a vacuum device is installed below to remove the sprayed high-pressure water jets and Mesophyll Alternatively, you could siphon it out and circulate only water.

[0047] <Example 1>

[0048] The following describes some examples.

[0049] Seven months after germination, pineapples from Ogimi Village, Okinawa Prefecture, were subjected to a study where leaves (weighing 75g) were cut from the base of discarded plants after the edible fruit had been harvested. These leaves were placed on a mounting device through which high-pressure water jets were passed, and high-pressure water jets were applied to the leaves at a speed of 7 m / s at an angle of 70 to 85 degrees relative to the leaf surface. A high-pressure jet device with a maximum pressure of 12 MPa was used to generate the high-pressure water jets. The water pressure of the high-pressure jet device was set to 5 MPa. The mounting device consisted of multiple cylindrical members arranged parallel to each other with a certain gap between them. Grooves were formed on the outer surface of these cylindrical members, and multiple grooves were provided along the axial direction.

[0050] A cyclone jet nozzle, which swirls the jet of water, was used for ejecting the high-pressure water jet. The distance between the nozzle and the leaves was 35 cm. The average particle size of the air bubbles mixed in the high-pressure water jet was 50 μm, and the mixing rate was 5%. The pineapples treated with the high-pressure water jet had a maximum fiber width of 200 μm and an average length of 450 mm. fiber bundle Obtained. Obtained fiber bundle Its dry weight (moisture content less than 10%) is 4.5g. Removed from the leaves. Mesophyll inside fiber bundle This was not recognized, and also, fiber bundle on the surface Mesophyll It was not accepted.

[0051] <Example 2>

[0052] Next, we will describe another example.

[0053] In Nanjo City, Okinawa Prefecture, a banana pseudostem (weighing 185g) measuring 80cm in length and 10cm in width, cultivated for making banana cloth from hand-spun yarn, was placed on a rod stand with grooves along its outer surface. High-pressure jet water was applied to the pseudostem at an angle of 65 to 80 degrees relative to its surface. The high-pressure jet water flow rate was 10m / second, and a cyclone jet nozzle that swirls the water was used at the outlet. The distance between the nozzle and the pseudostem was 50cm. The high-pressure jet water treatment resulted in banana fibers with a maximum fiber width of 230μm and an average length of 700mm. fiber bundle Obtained. Obtained fiber bundle The dry weight (moisture content less than 10%) was 6.1 g. Removed from the pseudostem. Mesophyll inside fiber bundle A small amount was observed, but the results were obtained fiber bundle on the surface Mesophyll This was not accepted. Also, fiber bundle They never interacted with each other. [Industrial applicability]

[0054] This invention utilizes leaves and pseudostems that would otherwise be discarded. Mesophyll Remove Fiber bundles extending in the longitudinal direction for 50 cm or more This allows for the extraction and subsequent use in the textile industry through spinning. [Explanation of Symbols]
