  Next, embodiments of the present invention will be described in detail based on the drawings. In FIG.1 and FIG.2, the code | symbol 10 is the raw fabric storage instrument of this invention. The original fabric storage device 10 includes an original fabric 16 formed by winding a film 14 around a substantially cylindrical paper tube (winding shaft) 12 (the original fabric 16 is formed from the paper tube 12 and the wound film 14. Is comprised of a paper tube 12, a pair of sleeves 18 attached to the paper tube 12, and a pair of support stands 21 for supporting the raw fabric 16 in the air. It is configured.

As shown in FIGS. 2 and 3, the paper tube 12 has a hollow portion 22 in the longitudinal direction. In the hollow portion 22, two convex portions (engaging portions) 30 shown in FIG. 2 that the sleeve 18 has are located at opposite positions on the inner peripheral surface near the one end 24 and the other end 26 of the paper tube 12. It has the recessed part (engaged part) 28 engaged. As shown in FIG. 3 (b), the recess 28 has a taper that becomes deeper from the central portion side to the one end 24 side or the other end 26 side of the hollow portion 22, and the bottom 29 is the inner peripheral surface of the hollow portion 22. The convex part 30 engaged with the concave part 28 comes into contact with the bottom side 29 and has one end 24 side from the center part side of the hollow part 22. Or it is comprised so that it may not move to the other end 26 side, and the convex part 30 is comprised so that it may not detach | leave from the center part side of the hollow part 22 to the one end 24 side or the other end 26 side.

  As shown in FIGS. 2, 4, and 5, the sleeve 18 includes a substantially cylindrical insertion portion 32 that is inserted into the hollow portion 22 of the winding shaft 12 and a rear end 34 in the rotation center axis C direction in the insertion portion 32. It is comprised from the knob | pick part 36 which follows. The insertion part 32 and the knob part 36 are integrally formed by resin molding. The raw material of the resin is not particularly limited as long as the plate piece 40 shown below can be elastically deformed, such as ABS (Acrylonitrile Butadiene Styrene).

  As shown in FIGS. 4 and 5A, two U-shaped cutouts 38 are provided at two locations on the same diameter direction of the insertion portion 32, so that the cutouts 38 are formed around the three sides. An arc-shaped plate piece portion 40 is formed. The convex portion 30 that engages with the concave portion 28 of the sleeve 18 is provided near the distal end 42 (shown in FIG. 5A) of the insertion portion 32 in the plate piece portion 40 in the outer circumferential direction. The plate piece portion 40 is made of an elastically deformable material and dimensions, and the convex portion 30 provided on the plate piece portion 40 can move elastically in the radial direction of the circular cross section of the insertion portion 32. As shown in FIG. 4B, both side surfaces 44 of the convex portion 30 that contact the concave portion 28 of the sleeve 18 are inclined with respect to the radial direction of the circular cross section of the insertion portion 32, and are convex to the concave portion 28. By rotating the sleeve 18 around the rotation center axis C from the state where the portion 30 is engaged, the convex portion 30 is detached from the concave portion 28 while the side surface 44 slides with respect to the opening portion of the concave portion 28, and the sleeve 18 is configured to be extracted from the paper tube 12.

  The direction in which the sleeve 18 is rotated around the rotation center axis C in order to disengage the convex portion 30 from the concave portion 28 is determined depending on the shape of the convex portion 30 and the concave portion 28 or the position of the convex portion 30 in the plate piece portion 40. You may comprise so that it can limit. For example, in the vicinity of the distal end 42 in the outer circumferential circle direction of the insertion portion 32 in the plate piece 40 so that the convex portion 30 can be rotated only from the distal end 42 in the outer circumferential circle direction of the insertion portion 32 toward the rear end in the outer circumferential direction. You may comprise so that the convex part 30 may be provided.

  As shown in FIG. 5B, the knob 36 has an octagonal outer periphery so that it is difficult to slip when gripped with one hand and rotated around the rotation center axis C. The outer periphery of the knob 36 may be a polygon such as a hexagon. The knob 36 is provided with an engaging groove 46 for engaging the tool so that it can be rotated using the tool. The knob portion 36 and the insertion portion 32 have a hollow portion 35 at the center for weight reduction.

  A pair of support stand 21 is comprised from a plate-shaped member, as shown to FIG.1 and FIG.6 (a). The material of each support stand 21 is not particularly limited as long as it has a strength capable of supporting the raw fabric 16, such as resin and wood. As shown in FIG. 6B, a through hole 48 through which the insertion portion 32 of the sleeve 18 passes is provided in the center portion of each support stand 21. The height H2 of the center C1 of the through-hole 48 is configured to be higher than the radius D1 (shown in FIG. 1B) of the original fabric 16 formed by winding the paper tube 12. Thereby, the paper tube 12 of the original fabric 16 can be fixed to the through hole 48 and the original fabric 16 can be supported in the air. The diameter of the outer circumferential circle of the through hole 48 is substantially the same as the diameter of the outer circumferential circle of the insertion portion 32 of the sleeve 18 so that the insertion portion 32 of the sleeve 18 can be inserted.

  As shown in FIG. 6C, there are two passage grooves through which the convex portion 30 of the sleeve 18 can pass when the insertion portion 32 of the sleeve 18 is passed through the through hole 48 as shown in FIG. 50 is provided. As shown in FIG. 1, the upper side 49 of the support stand 21 is formed in an arc shape having a larger radius than the outer circumference circle of the raw fabric 16. Thus, when a protective cover (not shown) is put on the pair of support stands 21, all of the original fabric 16 is placed between the pair of support stands 21 and the protective cover without contacting the protective cover to the original fabric 16. Can be stored underneath.

  Here, a distance L1 (shown in FIG. 3B) from the bottom 29 of the concave portion 28 of the paper tube 12 to the one end 24 or the other end 26 of the paper tube 12 and the knob 36 side of the convex portion 30 of the sleeve 18 are shown. Between the distance L2 (shown in FIGS. 4A and 5A) from the side surface 44 to the knob 36 and the thickness L3 of each support stand 21 (shown in FIG. 6A), As shown in FIG. 2, there is a relationship L2 = L1 + L3. Accordingly, when the sleeve 18 is fixed to the paper tube 12 by engaging the convex portion 30 of the sleeve 18 with the concave portion 28 of the paper tube 12, as shown in FIG. The support stand 21 can be held between the one end 24 or the other end 26.

  The effect of supporting and storing the original fabric 16 in the air using the original fabric storage device 10 having the above configuration will be described below. Unless otherwise specified, the operation will be described in chronological order.

  A film 14 is wound around the paper tube 12 by a winding device (not shown) to form an original fabric 16. The original fabric 16 is transported to a warehouse where the original fabric storage device 10 is disposed.

  In the warehouse, as shown in FIG. 7, a positioning block 62 having a V-shaped groove 60 is installed on the floor 58. The original fabric 16 is suspended by a crane (not shown) and placed in the V-shaped groove 60 of the block 62. The block 62 has a height H1 from the floor 58 of the rotation center axis C of the original fabric 16 placed in the V-shaped groove 60 to a height H2 from the bottom of the support stand 21 to the center C1 of the through hole 48 (see FIG. 6 (shown in (a)) or the same height H1 as H2. Thereby, the support stand 21 can be installed on the raw fabric 16 placed in the V-shaped groove 60 without being interfered with the floor 58. The block 62 may be configured to adjust the height of the V-shaped groove 60.

  Further, when the raw fabric 16 is placed in the V-shaped groove 60, the one end 24 and the other end 26 of the paper tube 12 need to protrude from the end portion 64 of the block 62 in the rotation center axis C direction. As a result, the support stand 21 can be placed on the original fabric 16 by bringing the support stand 21 into contact with the one end 24 and the other end 26 of the paper tube 12.

  Next, as shown in FIG. 8, the one support stand 21 constituting the pair of support stands 21 is brought into contact with one end 24 of the paper tube 12 while being moved on the floor 58. The insertion portion 32 is inserted in the vicinity of the through hole 48 of one support stand 21 and the one end 24 of the hollow portion 22 of the paper tube 12. At this time, the convex part 30 which one sleeve 18 has is allowed to pass through the passage groove 50 (shown in FIG. 6C) which the through hole 48 of one support stand 21 has. The insertion portion 32 of the one sleeve 18 is inserted in the vicinity of the through hole 48 of the one support stand 21 and the one end 24 of the paper tube 12 until the knob portion 36 contacts the one support stand 21. Accordingly, the periphery of the through hole 48 of the one support stand 21 is sandwiched between the knob portion 36 of the one sleeve 18 and the one end 24 of the paper tube 12.

  The insertion portion 32 of the one sleeve 18 is inserted in the vicinity of the one end 24 of the paper tube 12, and the periphery of the through hole 48 of the one support stand 21 is formed by the knob portion 36 of the one sleeve 18 and the one end 24 of the paper tube 12. When sandwiched, in the direction parallel to the rotation center axis C, the position of the convex portion 30 of one sleeve 18 coincides with the position of the concave portion 28 of the paper tube 12. As described in the description of the configuration, the distance L1 (shown in FIG. 3B) from the bottom 29 of the concave portion 28 near the one end 24 to the one end 24 in the paper tube 12 and the knob 30 of the convex portion 30 of the one sleeve 18. A distance L2 (shown in FIGS. 4A and 5A) from the side surface 44 on the portion 36 side to the knob 36 and a thickness L3 of each support stand 21 (shown in FIG. 6A) This is because there is a relationship L2 = L1 + L3 between them as shown in FIG.

  The insertion portion 32 of the one sleeve 18 is inserted in the vicinity of the one end 24 of the paper tube 12, and the periphery of the through hole 48 of the one support stand 21 is formed by the knob portion 36 of the one sleeve 18 and the one end 24 of the paper tube 12. When sandwiched, normally, in the circumferential direction of the paper tube 12, the position of the convex portion 30 of one sleeve 18 does not coincide with the position of the concave portion 28 near the one end 24. This is because it is difficult for an operator who inserts one sleeve 18 to confirm the position of the recess 28. For example, as shown in FIG. 9A, the position of the convex portion 30 of one sleeve 18 is shifted clockwise from the position of the concave portion 28 near one end 24. Thereby, the convex part 30 of the one sleeve 18 is pressed by the inner peripheral surface of the hollow part 22, and the plate piece part 40 of the one sleeve 18 is substantially centripetal of the paper tube 12 as shown in FIG. 9A. It is elastically deformed in the direction.

  Next, as shown in FIG. 9A, the one sleeve 18 is rotated counterclockwise, for example, and the convex portion 30 of the one sleeve 18 is rotated around the rotation center axis C. The position of the convex portion 30 of the one sleeve 18 rotated around the rotation center axis C eventually coincides with the position of the concave portion 28 near the one end 24 in the circumferential direction of the paper tube 12. As a result, the convex portion 30 of the one sleeve 18 is released from the pressing by the inner peripheral surface of the hollow portion 22, and the plate piece portion 40 of the one sleeve 18 is deformed in the substantially centrifugal direction of the paper tube 12. The convex portion 30 of the sleeve 18 is engaged with the concave portion 28 near the one end 24. As a result, the one sleeve 18 is fixed near the one end 24 of the paper tube 12.

  As described in the description of the configuration, as shown in FIG. 3B, the concave portion 28 becomes deeper as it goes from the center side of the hollow portion 22 toward the one end 24 side, and the bottom 29 is the inner peripheral surface of the hollow portion 22. The cross section of a substantially right triangle. As a result, the convex portion 30 of one sleeve 18 engaged with the concave portion 28 in the vicinity of the one end 24 moves to the one end 24 side from the central portion side of the hollow portion by coming into contact with the bottom side 29, so that the convex portion 30 is There is no separation from the central portion side of the hollow portion 22 toward the one end 24 side.

  In this manner, one sleeve 18 and one support stand 21 are fixed to the paper tube 12 of the original fabric 16 in the vicinity of one end 24 of the paper tube 12 of the original fabric 16. That is, in the vicinity of the one end 24 of the paper tube 12 of the original fabric 16, the paper tube 12, the one sleeve 18 and the one support stand 21 of the original fabric 16 are fixed to each other. Next, in the vicinity of the other end 26 of the paper tube 12 of the original fabric 16, the other sleeve 18 and the other support stand 21 are fixed to the paper tube 12 of the original fabric 16 in the same manner as the vicinity of the one end 24 of the paper tube 12. The paper tube 12, the other sleeve 18, and the other support stand 21 of the raw fabric 16 are fixed to each other. In this way, the pair of support stands 21 are fixed to the raw fabric 16.

  With the pair of support stands 21 fixed to the original fabric 16, the original fabric 16 is lifted and moved to a storage location of the original fabric 16 by a crane (not shown). In the storage place, the pair of support stands 21, the raw fabric 16, and the like are lowered onto the floor 58. Accordingly, the pair of support stands 21 support the raw fabric 16 in the air. A protective cover (not shown) is put on the original fabric 16 and the pair of support stands 21 supported by the pair of support stands 21, and the original fabric 16 is stored in a storage place for a predetermined period. As shown in FIG. 1B, when the original fabric 16 is hidden by the support stand 21 in a side view, the protective cover does not come into contact with the original fabric 16 and the static electricity is generated by the protective cover. Never do.

  When the original fabric 16 is used for manufacturing a liquid crystal film or the like, the stored original fabric 16 needs to be taken out from a storage location in order to manufacture the liquid crystal film or the like. First, the protective cover covering the original fabric 16 is removed, and the original fabric 16 is supported by a crane or the like (not shown) and placed on the block 62. Next, the one sleeve 18 is, for example, counterclockwise from the state in which the convex portion 30 of the one sleeve 18 is engaged with the concave portion 28 near the one end 24 of the paper tube 12 (the state shown in FIG. 9B). To be rotated. When one sleeve 18 rotates counterclockwise, the side surface 44 inclined with respect to the radial direction of the circular section of the insertion portion 32 slides against the opening of the recess 28 near the one end 24. The convex portion 30 of one sleeve 18 is separated from the concave portion 28 near one end 24. At this time, the plate piece portion 40 is elastically deformed in the centripetal direction of the circular cross section of the insertion portion 32.

  When the convex portion 30 of one sleeve 18 is disengaged from the concave portion 28 near one end 24, the one sleeve 18 is connected to the rotation center axis C from the vicinity of the one end 24 of the paper tube 12 and the through hole 48 of the one support stand 21. Extracted in parallel direction. When one sleeve 18 is extracted from the vicinity of one end 24 of the paper tube 12, the one sleeve 18 and the one support stand 21 are detached from the original fabric 16.

  Similar to the one sleeve 18, the other sleeve 18 is extracted from the vicinity of the other end 26 of the paper tube 12 and from the through hole 48 of the other support stand 21, and the other sleeve 18 and the other support stand 21 are original. Leave from anti-16. As a result, only the original fabric 16 is supported by the block 62.

  Next, the raw fabric 16 is supported by a crane or the like and conveyed to the manufacturing process. From the raw fabric 16 conveyed to the manufacturing process, the film 14 is unwound and a liquid crystal film or the like is manufactured.

  According to the original fabric storage device 10 of the present invention, the through hole 48 of the support stand 21 is provided at one end 24 or the other end of the winding shaft 12 constituting the original fabric 16 near one end 24 and the other end 26 of the paper tube 12. 26, the insertion portion 32 of the sleeve 18 is inserted into the through hole 48 and the hollow portion 22 of the paper tube 12, and the convex portion 30 of the sleeve 18 is engaged with the concave portion 28 of the paper tube 12, whereby the raw fabric 16 The paper tube 12, the pair of sleeves 18, and the pair of support stands 21 can be fixed to each other. Thereby, the raw fabric 16 can be easily stored and supported by the pair of support stands 21. In addition, since the paper tube 12, the pair of sleeves 18 and the pair of support stands 21 constituting the original fabric 16 are fixed to each other, the original fabric 16 is not detached from the support stand 21 due to vibration during transportation or the like. .

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the above-mentioned embodiment.

  For example, in the original fabric storage device 10 shown in FIGS. 1 and 2, a step 64 may be provided near one end 24 and the other end 26 of the paper tube 12 as shown in FIG. 10.

  In order to hold the support stand 21 between the step wall 66 of the paper tube 12 constituting the raw fabric 16 and the knob 36 of each sleeve 18, the length L4 of the step 64 of the paper tube 12 shown in FIG. Is the same as the thickness L3 of the support stand 21 (shown in FIG. 6A).
