Summary of the Invention
Problems to be Solved by the Invention
[0004] When using a carbon fiber sheet for the reinforcement and repair work of a tunnel as in Patent Document 1, preliminary preparations are required to carry the carbon fiber sheet into the construction site. Specifically, the carbon fiber sheet is pulled out from a roll-shaped raw fabric, cut to a length of about several meters (for example, 3 to 5 m), and then wound up to form a roll-shaped shipping form. Such an operation of forming the carbon fiber sheet into a roll-shaped shipping form is repeated many times according to the amount of the carbon fiber sheet used at the construction site.
[0005] The above process is complex and time-consuming, and requires at least two workers because it involves simultaneously holding down the pulled-out carbon fiber sheets and cutting them. Furthermore, the process of pulling out the carbon fiber sheets requires a large workspace, which necessitates using the floor of a work yard or similar area, forcing workers to maintain a crouched or bent-over posture for extended periods.
[0006] The present invention has been made in view of the above problems, and its main objective is to improve the efficiency, reduce manpower and space requirements for the process of winding sheet material from a roll of raw sheet material, cutting it to a desired length, and forming a roll body. [Means for solving the problem]
[0007] To achieve this objective, the present invention provides a sheet material winding device for winding sheet material from a roll of sheet raw material, cutting it to a predetermined length, and forming it into a roll body, comprising: a sheet cutter for cutting the sheet material in the width direction; a supply-side shaft positioned on one side of the sheet cutter and attached to the sheet raw material; a winding shaft positioned parallel to the supply-side shaft on the other end of the sheet cutter and winding the sheet material; and a device body comprising a frame having a cutter support portion installed at the top for supporting the sheet cutter, a supply-side bearing portion for supporting the supply-side shaft on one side, and a winding-side bearing portion for supporting the winding shaft on the other side, wherein one end of the winding shaft is provided with a handle for rotating the winding shaft on the winding-side bearing portion.
[0008] The sheet material winding device of the present invention is characterized by comprising a length measuring device located at the upper part of the frame, between the sheet cutter and the supply-side shaft, for measuring the length of the sheet material wound from the sheet roll towards the winding shaft.
[0009] The sheet material winding device of the present invention is characterized by having a sheet fall prevention member located at the upper part of the frame and below the sheet cutter, which holds the cut end of the sheet material cut by the sheet cutter.
[0010] The sheet material winding device of the present invention is characterized in that the supply-side bearing portion is installed on the inside of the frame instead of on one side of the frame.
[0011] The sheet material winding device of the present invention is characterized in that the sheet material is a carbon fiber sheet.
[0012] According to the sheet material winding device of the present invention, a handle provided on the winding shaft is operated to wind a predetermined length of sheet material from a roll of raw sheet material onto the winding shaft, and then a sheet cutter is operated to cut the sheet material, thereby forming a roll body made of sheet material. As a result, the operation of forming the roll body can be performed by a single worker, making it possible to improve work efficiency, reduce manpower, and save space.
[0013] Furthermore, by adjusting the height of the device as needed, workers can perform tasks while standing or sitting on a chair or similar object near the device. This eliminates the need to work in a crouched or bent-over position, as was done in the past, and significantly improves the working environment.
[0014] Furthermore, by providing a sheet fall prevention member on the frame to hold the cut ends of the sheet material cut by the sheet cutter, the need for workers to bend down and pick up the cut ends of the sheet material after cutting can be eliminated. Therefore, when forming a large number of rolls, it becomes possible to continuously form the rolls efficiently and with less strain on the worker's posture.
[0015] Furthermore, because the sheet material is wound from a roll of raw sheet material onto the winding shaft, a large workspace is not required. In addition, by installing the supply-side bearing that supports the supply-side shaft inside the frame, the raw sheet material attached to the supply-side shaft can be stored inside the frame. This makes the sheet material winding device more compact, allowing it to be placed in a narrow workspace.
[0016] In addition, by equipping the frame with a length measuring device that measures the length of the sheet material being wound from the sheet raw material to the winding shaft, it becomes possible to cut sheet material of the desired length from the roll of sheet raw material without waste.
[0017] By using the sheet material winding device described above, for example, if carbon fiber sheets used in tunnel repair and reinforcement work are formed into rolls, even when a large quantity of carbon fiber sheets is required, a single worker can quickly form rolls of carbon fiber sheets. Therefore, it is possible to contribute to shortening the overall construction period and reducing the number of workers. [Effects of the Invention]
[0018] According to the present invention, the process of winding sheet material from a roll of raw sheet material, cutting it to a predetermined length, and forming it into a roll can be performed by a single worker, thereby improving the efficiency, reducing manpower, and saving space in the roll forming process.

Mode for Carrying out the Invention
[0020] The sheet material winding device of the present invention is applicable to any sheet material such as paper, fabric, film, etc. In this embodiment, as an example, the case where a carbon fiber sheet (width about 50 cm to 1 m) is adopted as the sheet material will be cited, and the details will be described while referring to FIGS. 1 to 7.
[0021] ≪≪Sheet Material Winding Device≫≫ As shown in FIG. 1, the sheet material winding device 100 winds the carbon fiber sheet S from the roll-shaped sheet stock F by a predetermined length and then cuts it, and as shown in FIG. 2, forms the wound carbon fiber sheet S into a roll body R and enables it to be carried out. The sheet material winding device 100 that functions in this way includes, as shown in FIG. 3, a device body 10, a supply side shaft 40, a winding shaft 50, a sheet cutter 60, and a length measuring device 70.
[0022] ≪≪Device Body≫≫ As shown in FIG. 3, the device body 10 includes a substantially rectangular parallelepiped frame 20 and casters 30. The frame 20 is composed of four column members 21, a pair of lower girders 22, a pair of upper girders 23, a pair of lower beams 24, and a pair of upper beams 25, and a top plate 26, a supply side bearing portion 27, a winding side bearing portion 28, and a sheet drop prevention member 29 are provided.
[0023] A pair of lower beam members 22 are spaced apart and connect the lower ends of adjacent column members 21 in the short direction. Their length is longer than the spacing between the connected column members 21, and their ends protrude from the frame 20. Casters 30 are installed on the underside of each of these protruding portions. On the other hand, a pair of upper beam members 23 are spaced apart and connect the upper ends of adjacent column members 21 in the short direction, and cutter support parts 231 for supporting sheet cutters 60 are provided in the middle of the upper surface of each. Details of the sheet cutters 60 will be described later.
[0024] A pair of lower beam members 24 are positioned perpendicular to the lower girder members 22 with a gap between them, connecting the lower ends of adjacent column members 21 in the longitudinal direction. Similarly, a pair of upper beam members 25 are positioned perpendicular to the upper girder members 23 with a gap between them; one connects the upper ends of adjacent column members 21 in the longitudinal direction, and the other connects a pair of upper girder members 23 near the cutter support section 231. A top plate 26 is installed between these pairs of upper beam members 25, and a length measuring device is provided above it. Details of the length measuring device 70 will be described later.
[0025] In the frame 20 of the device body 10 configured as described above, a pair of supply-side bearings 27 are installed on the outer surface of one side (the side on which the top plate 26 is installed) that sandwiches the cutter support portion 231, and a pair of winding-side bearings 28 are provided on the outer surface of the other side.
[0026] The supply-side bearing section 27 rotatably supports the supply-side shaft 40, to which the roll-shaped sheet material F shown in Figures 1 and 2 is attached, and is provided in pairs on each side of the column member 21 connected by the lower beam member 24 and the upper beam member 25. Its shape, as shown in Figures 3 and 4(a), consists of a cantilever member 271 that extends from the side of the column member 21 in a direction parallel to the lower girder member 22 and the upper girder member 23, and a rod-shaped member 272a and a hook-shaped member 272b provided on its upper surface.
[0027] The rod-shaped member 272a and the hook-shaped member 272b are positioned with a gap between them, and the supply-side shaft 40 is supported in this gap. However, the height of the hook-shaped member 272b is formed to be higher than that of the rod-shaped member 272a, creating a space between the upper end of the rod-shaped member 272a and the hook-shaped member 272b. The supply-side shaft 40 is moved in and out of the gap between the rod-shaped member 272a and the hook-shaped member 272b using this space.
[0028] Thus, the supply-side bearing portion 27 is structured in such a way that the supply-side shaft 40 cannot easily come out. Furthermore, the upper surfaces of the rod-shaped member 272a and the hook-shaped member 272b, and the cantilever member 271 located between them, are formed as smooth surfaces so as not to hinder the rotation of the supply-side shaft 40. The smooth surfaces may be formed by any means.
[0029] The winding-side bearing section 28 rotatably supports the winding shaft 50 that winds the carbon fiber sheet S from the roll-shaped sheet raw material F as shown in Figures 1 and 2, and is provided in pairs on each side of the column member 21 connected by the lower beam member 24, as shown in Figure 3. Its shape, as shown in Figure 4(b), consists of a cantilever member 281 that extends from the side of the column member 21 in a direction parallel to the lower girder member 22 and the upper girder member 23, a pair of upright members 282 provided on its upper surface, and a retaining member 283.
[0030] The pair of upright members 282 consist of rods of different heights arranged with a gap between them, and the winding shaft 50 is supported in this gap. A retaining member 283 is provided at the upper end of the taller of the pair of upright members 282. The retaining member 283 is made up of a member that can select between an extended pin state and a retracted pin state. When the pin is extended, it closes the gap between the pair of upright members 282, and when it is retracted, it opens the gap between the pair of upright members 282. Therefore, when the pin of the retaining member 283 is in the retracted state, the winding shaft 50 can be inserted between the pair of upright members 282, and when the pin of the retaining member 283 is extended in this state, the winding shaft 50 is prevented from coming out.
[0031] The retaining member 283, which functions in this way, can be any member that can open and close the space between the pair of upright members 282, such as an index plunger. Furthermore, the upper surfaces of the pair of upright members 282 and the cantilever member 281 located between them are formed as smooth surfaces so as not to obstruct the rotation of the winding shaft 50. The smooth surfaces may be formed by any means.
[0032] As shown in Figure 3, the sheet fall prevention member 29 is installed at the upper end of the frame 20, below the sheet cutter 60 supported by the cutter support part 231, so as to form a plane with the top plate 26 and to connect a pair of upper beam members 23. As a result, as shown in Figure 2, when the carbon fiber sheet S is cut by the sheet cutter 60, the cut end of the carbon fiber sheet S is caught in the sheet fall prevention member 29, thus preventing it from falling into the frame 20.
[0033] <<<Supply shaft 40 and winding shaft 50>>> As described above, the winding shaft 50 is supported by a pair of winding-side bearings 28, and as shown in Figure 4(b), it comprises a shaft body 51, a handle 52, a shaft locking device 53, a sheet cylinder retainer 54, and an anti-rotation device 55.
[0034] The shaft body 51 is a core rod for winding the carbon fiber sheet S wound from the sheet raw material F, and the handle 52 is attached to one end of the shaft body 51. As a result, when the winding shaft 50 is mounted so as to span across the pair of winding side bearings 28, the operator can use the handle 52 to rotate the shaft body 51 around its axis. In addition, a shaft locking device 53 is attached to the end of the shaft body 51 where the handle 52 is installed.
[0035] The shaft locking device 53 has an outer flange portion 531 and an inner flange portion 532, and is positioned so that the outer flange portion 531 is on the handle side, sandwiching the winding side bearing portion 28. This suppresses the movement of the winding shaft 50 in the axial direction of the shaft body 51. In addition, the shaft body 51 is provided with a seat cylinder retainer 54 and an anti-rotation device 55.
[0036] The sheet cylinder retainer 54 consists of a ring-shaped member whose inner diameter is approximately smaller than the outer diameter of the shaft body 51. After inserting the sheet cylinder B, which winds the carbon fiber sheet S, onto the shaft body 51, the sheet cylinder B is positioned together with the inner flange portion 532 of the shaft locking device 53 to fix the position of the sheet cylinder B relative to the shaft body 51.
[0037] The anti-free rotation device 55 prevents the seat cylinder B from rotating freely relative to the shaft body 51. Its structure can be either fixed to or pressed against the shaft body 51, allowing them to rotate together. While this embodiment uses an index plunger as an example, bolts could also be used to fix the seat cylinder B to the shaft body 51.
[0038] As shown in Figure 3, the supply-side shaft 40 is supported by a pair of supply-side bearings 27 as described above, and has the same configuration as the winding shaft 50. Specifically, it comprises a shaft body 41 that functions as a core rod inserted into a roll of sheet material F, a handle 42, a shaft locking device 43, a material holding device 44, and an anti-rotation device 45.
[0039] The handle 42 is attached to one end of the shaft body 41, and the shaft locking device 43 has an outer flange 431 and an inner flange 432. By sandwiching the supply-side bearing 27 located on the handle 42 side with these, the movement of the shaft body 41 in the axial direction is suppressed. Furthermore, a raw material holder 44 is detachably provided on the shaft body 41, which suppresses the movement of the sheet raw material F in the axial direction of the shaft body 41. The anti-free-rotation device 45 prevents the cylindrical core of the sheet raw material F from rotating freely relative to the shaft body 41.
[0040] Sheet cutter As shown in Figure 1, the sheet cutter 60 is positioned parallel to the supply shaft 40 and the winding shaft 50 and is supported by a pair of cutter support parts 231 provided on the frame 20 of the device body 10. Any cutter available on the market can be used as long as it has a shape capable of cutting carbon fiber sheets S, but in this embodiment, the "Rakuraku Cutter" (product name) is used. Its general structure is as follows.
[0041] As shown in Figures 3 and 4(a), the sheet cutter 60 includes a cutter rail 62 that guides the movement direction of the cutter body 61, and a sheet contact 63 positioned below the cutter rail 62, on which a carbon fiber sheet S is placed. The cutter rail 62 and the sheet contact 63 are connected on one side in the longitudinal direction (the direction in which the cutter rail 62 extends) via a rotating shaft 64 parallel to it.
[0042] In this configuration, the sheet cutter 60 is positioned such that the cutter rail 62 is parallel to the supply shaft 40 and the winding shaft 50, and the rotation axis 64 is located on the side where the supply shaft 40 is installed. The carbon fiber sheet S is then positioned to move between the cutter rail 62 and the sheet contact 63 in a direction perpendicular to the cutter rail 62.
[0043] In this state, under normal circumstances, the cutter rail 62 is rotated upward around the rotation axis 64 (i.e., there is a gap between the cutter rail 62 and the sheet contact 63). On the other hand, during cutting, as shown in Figure 6(a), the cutter rail 62 is rotated downward around the rotation axis 64 to hold the carbon fiber sheet S between it and the sheet contact 63. In this state, the carbon fiber sheet S is cut by moving the cutter body 61 along the cutter rail 62.
[0044] <<Length measuring device>> As shown in Figure 1, the length measuring device 70 can be any measuring device available on the market that can measure the length of the carbon fiber sheet S wound from the sheet raw material F, but in this embodiment, the "Handy Measure Table (product name)" is used. To outline its structure, the length measuring device 70 consists of a measuring roller 71 that measures the distance it has rotated, a display box 72 that displays the measured value, and a mounting device 73 connected to the display box 72 via a biasing device.
[0045] In this configuration, the length measuring device 70 is mounted on the frame 20 via a mounting fixture 73 so that the measuring roller 71 rotates in the direction in which the carbon fiber sheet S moves (in a direction perpendicular to the supply shaft 40 and the winding shaft 50) and contacts the upper surface of the top plate 26 of the frame 20. The carbon fiber sheet S is then placed between the measuring roller 71 and the top plate 26. This allows the length of the carbon fiber sheet S being wound from the sheet raw material F towards the winding shaft 50 to be measured by the measuring roller 71 of the length measuring device 70.
[0046] Thus, the sheet material winding device 100 has a structure that winds the carbon fiber sheet S from the roll of sheet material F onto the winding shaft 50 and cuts it, eliminating the need for a large work area. Furthermore, by adjusting the height of the device body 10 as appropriate, the worker can perform the work while standing or sitting on a chair or similar near the device body 10. As a result, the need to work in a crouched or bent-over position, as in conventional methods, can be eliminated, and the working environment can be greatly improved.
[0047] <<<Method for forming rolled bodies>>> An example of a procedure for winding a carbon fiber sheet S of a predetermined length from a roll of raw sheet material F, then cutting it and forming a roll body R, using the sheet material winding device 100 having the above configuration, is shown below, as shown in Figure 2.
[0048] First, as shown in Figure 5(a), the sheet roll F is attached to the shaft body 41 of the supply shaft 40, and then mounted so as to span across the pair of supply bearings 27 provided on the frame 20 of the device body 10. Next, the end of the carbon fiber sheet S pulled out from the sheet roll F is passed in the following order: between the measuring roller 71 of the length measuring device 70 and the top plate 26 of the frame 20, and then between the cutter rail 62 of the sheet cutter 60 and the sheet contact 63. At this time, the cutter rail 62 of the sheet cutter 60 is spaced apart from the sheet contact 63.
[0049] Next, a sheet tube B, as described with reference to Figure 4(b), is inserted into the shaft body 51 of the winding shaft 50, which is mounted so as to span across a pair of winding-side bearing parts 28 provided on the frame 20 of the device body 10, and is fixed to the shaft body 51 with an anti-free rotation device 55. The end of the carbon fiber sheet S is then fixed to this sheet tube B. At this time, the sheet tube B is sandwiched between the inner flange 532 of the shaft locking device 53 and the sheet tube retaining device 54, fixing the position of the sheet tube B.
[0050] Subsequently, the operator rotates the shaft body 51 using the handle 52, causing the carbon fiber sheets S to be wound onto the shaft body 51 sequentially from the sheet roll F. During the winding of the carbon fiber sheets S sequentially from the sheet roll F, the measuring roller 71 of the length measuring device 70 rotates together with the carbon fiber sheets S moving on the top plate 26 of the frame 20, measuring the distance the carbon fiber sheets S have traveled.
[0051] The operator checks the length displayed in the display box 72 and operates the handle 52 until the desired length is reached. When the carbon fiber sheet S wound on the winding shaft 50 reaches the desired length, the operator stops operating the handle 52 and cuts the carbon fiber sheet S. If too much of the carbon fiber sheet S is wound, the operator can fix the cylindrical core of the sheet roll F to the shaft body 41 with the anti-free rotation device 45, and then use the handle 42 on the supply shaft 40 to rewind the carbon fiber sheet S back onto the sheet roll F.
[0052] As shown in Figure 6(a), the cutting operation involves rotating the cutter rail 62 of the sheet cutter 60 downwards around the rotation axis 64, thereby clamping the carbon fiber sheet S between the cutter rail 62 and the sheet contact 63. In this state, as shown in Figure 6(b), the cutter body 61 is moved along the cutter rail 62 in the width direction of the carbon fiber sheet S, thereby cutting the carbon fiber sheet S.
[0053] As a result, a roll body R, which has been wound and cut from the sheet raw material F, is formed on the winding shaft 50, as shown in Figure 2. For example, as shown in Figure 2, after securing the end of the carbon fiber sheet S with masking tape or the like, the winding shaft 50 is removed from the winding side bearing 28, and the roll body R is pulled out from the shaft body 51. This allows the roll body R to be transported out.
[0054] Since this series of operations can be performed by a single worker, it is possible to improve the efficiency and reduce the number of people required to form a roll body R made of carbon fiber sheets S of the desired length. Furthermore, the cut end of the carbon fiber sheet S cut by the sheet cutter 60 is secured to the sheet fall prevention member 29, as explained with reference to Figure 3, and does not fall inside the frame 20. Therefore, the work of a worker bending down to pick up the cut end of the carbon fiber sheet S after cutting is eliminated.
[0055] As a result, when forming a large quantity of roll bodies R, the cut end of the carbon fiber sheet S on the sheet fall prevention member 29 is inserted and passed between the cutter rail 62 and the sheet contact 63 of the sheet cutter 60. After this, a newly prepared sheet tube B is attached to the shaft body 51 of the winding shaft 50, the cut end of the carbon fiber sheet S is fixed to the sheet tube B, and the above procedure is repeated. This makes it possible to form a large quantity of roll bodies R continuously and efficiently while minimizing the burden on the operator's posture.
[0056] Therefore, if carbon fiber sheets S used in tunnel repair and reinforcement work are formed into rolls R using a sheet material winding device 100, even when a large quantity of carbon fiber sheets S are required, one worker can quickly form the rolls R. This contributes to shortening the overall construction period and reducing the number of workers required.
[0057] The sheet material winding device 100 of the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications are possible without departing from the spirit of the present invention.
[0058] For example, in this embodiment, as shown in Figure 3, a pair of supply-side bearings 27 that support the supply-side shaft 40 are installed on the outer side surface of the column member 21 so as to protrude outward from the frame 20. However, the embodiment is not limited to this, and as shown in Figure 7, they may also be installed on the inner side surface of the column member 21 so as to protrude inward from the frame 20. In this case, the supply-side shaft 40 with the sheet raw material F attached can be housed inside the frame 20, making the sheet material winding device 100 more compact. Therefore, the sheet material winding device 100 can be introduced even in confined work environments.
[0059] Furthermore, in this embodiment, a handle 42 is provided not only on the winding shaft 50 but also on the supply shaft 40, although the handle 42 on the supply shaft 40 may be omitted. Moreover, the rotation of the supply shaft 40 and the winding shaft 50 is not limited to operation of the handles 42 and 52 by an operator, but may be operated electrically or otherwise.
