  In the dismantling method of the tile carpet 1 according to the embodiment of the present invention, as shown in FIG. 2, for example, a base cloth 3 formed in a rectangular flat plate shape and the one side surface in the thickness direction of the base cloth 3 are erected. Tiles comprising a looped pile yarn 5 and a packing layer (packing material) 7 formed in, for example, a rectangular flat plate shape and covering the other surface in the thickness direction of the base fabric 3. The carpet 1 is dismantled.

  The tile carpet 1 is used by laying a plurality of tile carpets 1 on the floor of a building such as a building.

  In the tile carpet 1, the vertical and horizontal dimensions of the base fabric 3 (dimensions in the direction orthogonal to the thickness direction) and the vertical and horizontal dimensions of the packing layer 7 (dimensions in the direction orthogonal to the thickness direction) coincide with each other. ing. Further, the base fabric 3 and the packing layer 7 overlap each other in the thickness direction, and when viewed from the thickness direction of the base fabric 3 and the packing layer 7, all of the base fabric 3 has the packing layer 7. All are overlapping. Thereby, the tile carpet 1 is also formed in the rectangular plate shape.

  The thickness direction of the base fabric 3 is the vertical direction (the vertical direction in FIGS. 1 and 2), one surface in the thickness direction of the base fabric 3 is the upper side, and the other surface in the thickness direction of the base fabric 3 is the lower side Then, the loop-shaped pile yarn 5 stands up (projects) upward from the upper surface of the base fabric 3 in a form like a towel cloth. Here, one loop-shaped pile yarn 5 will be described. A portion of one loop-shaped pile yarn 5 protruding upward from the upper surface of the base fabric 3 has a form in which the “U” shape is turned upside down (reverse “U” shape). In the tile carpet 1, a plurality (a large number) of pile yarns 5 having an inverted “U” shape are erected at a predetermined density from the entire surface of one surface (upper surface) in the thickness direction of the base fabric 3. The protruding heights of the pile yarns 5 from the upper surface of the base fabric 3 are substantially equal to each other.

  More specifically, in the tile carpet 1, the pile yarn 5 protrudes in an inverted “U” shape on the upper surface of the base fabric 3 and does not protrude on the lower surface of the base fabric 3. After the base fabric 3 is sewed, the packing material 7 is attached to the lower surface of the base fabric 3 by using, for example, an adhesive. As a result, the entire pile yarn 5 has an elongated meandering shape, but the portion protruding from the upper surface of the base fabric 3 has an inverted “U” shape. In addition, as already understood, the pile yarn 5 is provided along with the direction orthogonal to the paper surface of FIG. 1 and FIG.

  The base fabric 3 is made of, for example, polypropylene (Polypropylene; PP), the pile yarn 5 is made of, for example, polypropylene or polyamide (Polyamide; PA), and the packing material 7 is made of, for example, poly It consists of vinyl chloride (Polyvinyl Chloride; PVC).

  The method for dismantling the tile carpet 1 is to disassemble the tile carpet 1 that has been used for a long period of time and spread over a floor of a building or the like, and includes a first step, a second step, and a removal step. Yes.

  In the first step, the pile yarn 5 is straightened by cutting the tip portion of the pile yarn 5 (the upper end portion of the inverted “U” -shaped pile yarn 5 rising from the upper surface of the base fabric 3). To do.

  If the standing height value is “h” from the upper surface of the base fabric 3 of the inverted “U” -shaped pile yarn 5 before cutting in the first step, the first step starts from the upper surface of the base fabric 3. A portion of the pile yarn 5 from the upper end of the upside-down inverted “U” -shaped pile yarn 5 to a position lowered downward by about h / 20 to h / 3 is cut with a cutter (plain cutter) 9. By removing (by cutting at the line segment L1 in FIG. 2 and removing the upper part from the line segment L1), the pile yarn 5 rising from the upper surface of the base fabric 3 is formed in an “I” shape. . In the first step, the pile yarn 5 is straightened. However, when the pile yarn 5 has a habit or the like, the pile yarn 5 may be bent.

  In FIG. 1 and FIG. 2, one meandering long pile yarn 5 is stretched in the left-right direction of FIG. 1 and FIG. 2 (direction perpendicular to the stretching direction of the rotation center axis C1 of the cutter 9). The long pile yarn 5 may be stretched in a direction perpendicular to the paper surface of FIG. 1 or FIG. 2 or in a direction inclined with respect to the paper surface.

  In the second step, after the pile yarn 5 is cut in the first step, the base end portion of the pile yarn 5 (the lower end portion of the inverted “U” -shaped pile yarn 5 standing from the upper surface of the base fabric 3) ) To lower the standing height of the pile yarn 5.

  That is, when the value of the standing height from the upper surface of the base fabric 3 of the pile yarn 5 linearized in the first step is “j”, the pile yarn 5 is cut at the lower end portion in the second step. By doing so (by cutting at the line segment L2 in FIG. 2 and removing the upper part from the line segment L2), the value of the standing height from the upper surface of the base fabric 3 of the pile yarn 5 is set to “0”. However, in practice, it is set to about 0 to j / 5.

  In the removing step, after the base end portion of the pile yarn 5 is cut in the second step, the base fabric 3 is removed together with the pile yarn 5 remaining after the second step over a predetermined thickness.

  More specifically, in the removing step, the upper surface side of the base fabric 3 is scraped off to a predetermined thickness (by cutting at the line segment L3 in FIG. 2 to remove the upper portion from the line segment L3), thereby removing the base fabric. The thickness of 3 is, for example, about half the thickness of the base fabric 3 of the tile carpet 1 before dismantling.

  By the way, in the first step, as shown in FIG. 8, after the tip portion of the pile yarn 5 is cut in a partial area A <b> 1 of the tile carpet 1, the pile yarn is cut in another partial area A <b> 2 of the tile carpet 1. 5 is cut off.

  That is, in the first step, the tip end portion of the pile yarn 5 of the entire tile carpet 1 is cut into a plurality of times (for example, twice). When cutting the tip of the pile yarn 5 in a partial area A1 of the tile carpet 1 (when cutting the first time in the first step), a part of the area other than the partial area A1 is: The tile carpet 1 is used to prevent problems such as turning up and lifting of the tile carpet 1 due to the above-mentioned cutting and to prevent the tile carpet 1 from improperly behaving.

  For example, the cutting of the tip portion of the pile yarn 5 is performed in the same form as the cylindrical cutting of a flat milling cutter (plane cutter) 9. In this case, although the plain cutter 9 is located above the tile carpet 1, both sides of the plain cutter 9 in the extending direction of the rotation center axis C1 of the plain cutter 9 (the tip portion of the pile yarn 5 is not cut). In the area A2), the tile carpet 1 is pressed from above by the tile carpet holding member 11 to prevent problems such as turning up and lifting of the tile carpet 1 due to the cutting.

  In the second step, similarly to the first step, the base end portion of the pile yarn 5 is cut in the partial area A1 of the tile carpet 1, and then the pile is formed in the other partial area A2 of the tile carpet 1. The base end portion of the yarn 5 is cut.

  When cutting the second time in the first step (when cutting the area A2), in the same way as when cutting the first time, the inappropriate behavior such as lifting of the tile carpet 1 is eliminated. Yes.

  Similarly to the first step and the second step, the removing step is also performed with the pile yarn 5 remaining after the second step over the predetermined thickness in the partial area A1 of the tile carpet 1. After that, the base fabric 3 is removed together with the pile yarn 5 remaining after the second step over a predetermined thickness in the other partial area A2 of the tile carpet 1.

  In addition, before performing a 1st process, the upper surface (surface in which the pile thread | yarn 5 is standing) of the tile carpet 1 is wash | cleaned with a brush. Further, the packing material 7 after the removing step, a part of the base fabric 3, and the slightly left pile yarn 5 are finely pulverized.

  According to the dismantling method of the tile carpet 1, the tip of the loop pile yarn 5 is cut in the first step to make the pile yarn 5 straight, and in the second step, the base of the straight pile yarn 5 is cut. Since the height of the pile yarn 5 is lowered by cutting the end portion (lower end portion of the pile yarn 5), the value of the cutting resistance when the pile yarn 5 is cut can be reduced, and the pile yarn 5 is cut. Problems such as lifting of the tile carpet 1 at the time can be prevented, and the pile yarn 5 can be accurately separated from the base fabric 3 and the packing material 7.

  Moreover, according to the dismantling method of the tile carpet 1, since the base fabric 3 is removed together with the pile yarn 5 remaining over a predetermined thickness in the removing step, the pile yarn 5 remaining after the cutting in the second step is removed. Can be removed more accurately. That is, the pile yarn 5 and the base fabric 3 that are attached to the packing material 7 can be reduced.

  Further, according to the method for disassembling the tile carpet 1, in the first step, after cutting the tip portion of the pile yarn 5 in the partial area A1 of the tile carpet 1, the other partial area A2 of the tile carpet 1 is obtained. In the second step, after the base end portion of the pile yarn 5 is cut in the partial area A1 of the tile carpet 1, the other partial area A2 of the tile carpet 1 is cut. Since the base end portion of the pile yarn 5 is cut, the cutting resistance value when the pile yarn 5 is cut can be further reduced.

  Further, in the first step and the second step, the tile carpet 1 can be pressed in an area where the pile yarn 5 is not cut by the cutter 9, so that the tile carpet is used in the first step and the second step. 1 improper behavior can be eliminated.

  Further, in the removal step, the improper behavior of the tile carpet 1 can be eliminated in the same manner as in the first step and the second step.

  By the way, the above-described method is performed using, for example, a tile carpet disassembling apparatus 13 described below.

  As described above, the tile carpet disassembling apparatus 13 includes the base fabric 3, the loop-shaped pile yarn 5 erected from one surface of the base fabric 3, and the packing material covering the other surface of the base fabric 3. 7 is a device that disassembles the tile carpet 1 that is configured to include a first cutting unit 15, a second cutting unit 17, and a removal unit 19 (see FIG. 7). .

  In the 1st cutting part 15, the front-end | tip part of the pile thread | yarn 5 is cut | disconnected. In the second cutting portion 17, the pile yarn 5 is cut by the first cutting portion 15, and then the base end portion of the pile yarn 5 is cut. In the removing unit 19, the base end of the pile yarn 5 is cut by the second cutting unit 17, and then the pile yarn 5 remaining after the base fabric 3 is cut by the second cutting unit 17 over a predetermined thickness They are removed (see line segments L1, L2, and L3 in FIG. 2).

  Further, as shown in FIG. 8, the first cutting section 15 cuts the tip end portion of the pile yarn 5 in a partial area A1 of the tile carpet 1 and then in the other partial area A2 of the tile carpet 1. The top end portion of the pile yarn 5 is configured to be cut. Similarly to the first cut portion 15, the second cut portion 17 is configured to cut the base end of the pile yarn 5 in a partial region A1 of the tile carpet 1. After the portion is cut, the base end portion of the pile yarn 5 is cut in the other partial area A2 of the tile carpet 1. Similarly to the first cutting unit 15 and the second cutting unit 17, the removing unit 19 removes a part of the base fabric 3 in a partial region A 1 of the tile carpet 1 and then removes the other part of the tile carpet 1. It is comprised so that a part of base fabric 3 may be removed in area | region A2.

The tip 73 may be provided on the outer periphery of the cutter main body 71 such that the ridgeline (one of the two long sides of the rectangular side surface) is a cutting edge. In this case, one cutter body 71 may be used as one set of cutter body 71.

  The upper roller 61 is also formed in a columnar shape, the central axis extends in the width direction, and one end of the central axis in the extending direction is one of the pair of cutters and the upper roller support member 57. The other end of the central axis in the extending direction is rotatably supported by the upper roller support member 57, and the other cutter / upper roller support member 57 of the pair of cutter / upper roller support members 57 is rotatable. It is supported.

  A plurality of upper rollers 61 (for example, two) are provided. One upper roller 61 is positioned above each lower roller 63 in the vertical direction, and is positioned in front of the cutter 9 in the front-rear direction. Yes. The other upper roller 61 is positioned above each lower roller 63 in the vertical direction, and is positioned behind the cutter 9 in the front-rear direction. The positions of the upper rollers 61 coincide with each other in the vertical direction.

  Further, the lower end of the upper roller 61 and the upper end of the lower roller 63 are spaced apart by a predetermined dimension in the vertical direction (the value of the dimension between the lower surface of the tile carpet 1 and the line segment L1 in FIG. 2). . This interval can be finely adjusted by appropriately changing the thickness (dimension in the vertical direction) of the spacer 65.

  In addition, you may be comprised so that the position of the upper roller 61 can be adjusted with respect to the position of the cutter 9 in an up-down direction.

  Each upper roller 61 rotates in a predetermined direction in synchronization with the lower roller 63 and the cutter 9 by an actuator such as a motor (not shown). Then, the tile carpet 1 conveyed by the lower roller 63 is sandwiched in cooperation between the lower roller 63 and the upper roller 61, and prevents the tile carpet 1 from being lifted, and resists the cutting resistance of the pile yarn 5 by the cutter 9. Thus, the tile carpet 1 can be forcibly fed from the front side to the rear side.

  The tile carpet pressing member 11 has an outer diameter formed in a rectangular parallelepiped shape, and is integrated with the pair of cutter / upper roller support member 57 between the pair of cutter / upper roller support member 57 (or the base member 55). Is provided.

  As shown in FIGS. 4 and 5, the tile carpet pressing member 11 is provided with a recess 75 and a through hole 77 into which the core material 69 of the cutter 9, the cutter main body 71, and the chip 73 enter. And the chip | tip 73 of the cutter 9 protrudes from the planar lower surface of the tile carpet pressing member 11. FIG. One upper roller 61 of the two upper rollers 61 is positioned in front of the cutter 9 and the tile carpet pressing member 11 in the front-rear direction, and the other upper roller 61 of the two upper rollers 61 is It is located behind the cutter 9 and the tile carpet pressing member 11 in the front-rear direction.

  The tile carpet holding member 11 holds the tile carpet 1 conveyed by the lower roller 63 from the upper side, and prevents the tile carpet 1 from being lifted by the cutting resistance of the pile yarn 5 by the cutter 9. .

  In addition, you may be comprised so that the position of the tile carpet pressing member 11 can be adjusted with respect to the position of the cutter 9 in an up-down direction.

  The first first cutting portion 15A can cut the pile yarn 5 in the area A1 shown in FIG. 8 of the tile carpet 1.

  The position of the lower roller 63A (see FIG. 2) located directly below the cutter 9 among the lower rollers 63 can be adjusted independently of the other lower rollers 63. It may be configured as follows.

  The first first cutting portion 15A is integrally installed on the gantry 67 on the gantry 67 (see FIG. 7).

  The second first cutting portion (first cutting portion located on the left side in FIG. 7) 15B is configured in the same manner as the first first cutting portion 15A, and the stand 67 (see FIG. 7) is integrally installed on the pedestal 67. However, since it is necessary to cut the pile yarn 5 in the area A2 shown in FIG. 8 of the tile carpet 1, the position of the cutter main body portion 71 in the width direction is the second first cutting portion 15B. This is different from the first first cutting portion 15A.

  The second cutting section 17 (17A, 17B) and the removal section 19 (19A, 19B) are also configured in the same manner as the first cutting section 15 (15A, 15B), and are on the mount 67 (see FIG. 7). It is integrally installed on the gantry 67.
