  The single-wafer medium storage device 1 according to the present embodiment is provided in the middle of a production line of a factory, for example. When trouble occurs in a post-process, the single-wafer medium (for example, chemical etching) Used to maintain production efficiency by temporarily retracting the circuit board) from the production line and suppressing the stop of the production line. Such an apparatus 1 is also used in the case where a trouble occurs unless the single-sheet medium in the previous process is quickly evacuated from the production line. In particular, when it is necessary to quickly evacuate the sheet-fed medium, it is important that the sheet-fed medium can be quickly and continuously stored in the sheet-fed medium storage device 1 and the amount of the sheet-fed medium that can be stored is large. . In addition, the sheet | seat medium accommodated in the sheet | seat medium accommodating apparatus 1 of this Embodiment has flexibility, for example, paper, a film, a metal thin plate, etc. correspond.

  As shown in FIG. 1 and FIG. 2, the sheet-fed medium storage device 1 according to the present embodiment has a substantially cylindrical shape having a caster 10, a pedestal 20, and a shaft 32 that is detachably and rotatably supported by the pedestal 20. A storage roll 30 having a shape, a protective raw material supply unit 40 for supplying the protective raw material 48 to the storage roll 30, and a tributary conveyance unit 50 for conveying the sheet medium to the storage roll 30 are provided. . Further, the protective raw material supply unit 40 includes a protective raw material roll 42 for supplying the protective raw material 48, a protective raw material guide roll 44, and a nip roll 46. Further, the single-sheet medium storage device 1 can be connected to a conveyance mechanism 60 provided in a production line or the like, and a single-sheet medium conveyed by the conveyance mechanism 60 is selected by the movable conveyance unit 62 described later as the apparatus 1. Can be branched. In the present embodiment, the movable conveyance unit 62 is configured as a part of the conveyance mechanism 60. Details of each component of the single-sheet medium storage device 1 will be described below.

  As described above, the sheet medium storage device 1 of the present embodiment is provided with the caster 10 so that the entire device 1 can be easily moved. Further, since the storage roll 30 is detachably attached to the pedestal 20 via the shaft 32, only the storage roll 30 can be detached from the pedestal 20 and transported. Furthermore, since the storage roll 30 has a substantially cylindrical shape, the storage roll 30 can be easily transported.

  In this way, since the storage roll 30 is easily transported, a so-called unwinding machine is installed in a space or the like having enough room in the factory, and the sheet-fed medium from the storage roll 30 is used by using the unwinding machine. Unwinding may be performed. In this case, the entire factory space can be used effectively. The unwinding of the storage roll 30 may be performed manually.

  As shown in FIGS. 1 and 2, the storage roll 30 is supported by the pedestal 20 so as to be rotatable about a shaft 32 extending in the horizontal direction (that is, the direction orthogonal to the paper surface in FIG. 1). The storage roll 30 is driven in the arrow direction shown in FIG. Specifically, the drive unit 70 has a drive motor, and the storage roll 30 is rotated by the drive motor. Further, the sheet medium conveyed to the storage roll 30 by the tributary conveyance unit 50 described later is stored by being wound around the outer peripheral surface of the storage roll 30 together with the protective raw material 48 supplied from the protective raw material supply unit 40. It has become so. Thus, since the surface of the sheet medium is wound around the storage roll 30 in a state in which the surface of the sheet medium is in contact with the protection raw fabric 48, the surface of the sheet medium can be protected during storage. Yes. The drive speed of the storage roll 30 by the drive unit 70 is determined by a control unit 80 such as a CPU based on the conveyance speed of the sheet medium by the conveyance mechanism 60 described later.

  Further, as described above, the sheet medium has flexibility, and is stored in a state of being bent along the shape of the outer peripheral surface of the storage roll 30 wound together with the protection raw fabric 48. Further, although the shape of the sheet medium indicated by the reference symbol W in FIG. 2 is a rectangular shape, the shape of the sheet medium is not limited to the rectangular shape, and is a square shape, a polygonal shape, a circular shape, or the like. It may be. As for the posture of the single-sheet medium stored in the storage roll 30, as shown in FIG. 2, the axial direction of the storage roll 30 and the longitudinal direction of the single-sheet medium (that is, the left-right direction in FIG. 2). It is not limited to an aspect that substantially matches. Even when the sheet medium is slightly inclined, the sheet medium can be stored in the storage roll 30 without damaging the sheet medium.

  Further, as shown in FIG. 1, a storage roll 30 having a predetermined outer diameter is used. The size of the outer diameter is such that the sheet medium stored in a bent state along the outer peripheral surface of the storage roll 30 does not cause plastic deformation, such as the thickness, material, processing state, etc. It is decided according to. As a result, the single-wafer medium stored in the storage roll 30 in a bent state can be substantially changed without being changed in shape before being stored in the storage roll 30 and after being unwound from the storage roll 30. The same shape can be maintained.

  1 and 2 includes a protective raw roll 42 for supplying a belt-shaped protective raw fabric 48 made of a film such as polyethylene terephthalate (PET), and the protective raw fabric 48 is a tributary conveyance. The protective raw material guide roll 44 for guiding along the portion 50 and the nip roll 46 for applying a predetermined pressing force to the outer peripheral surface of the storage roll 30 are configured. Further, the protective film guide roll 44 is movable in the left-right direction in FIG. 1, and the tension of the protective film 48 can be adjusted by moving the protective film guide roll 44. It has become. By adopting such a configuration, the protective raw fabric 48 can be continuously supplied to the storage roll 30, and wrinkles are prevented from being generated when the protective raw fabric 48 is wound around the storage roll 30. Be able to.

  Further, not only the storage roll 30 described above but also the protective raw roll 42 is driven by the drive unit 70. Specifically, the power by the drive motor of the drive unit 70 is transmitted to the protective raw roll 42 by a power transmission mechanism such as a gear, so that the storage roll 30 and the protective raw roll 42 are combined by the control unit 80. It comes to drive. In this case, the control unit 80 controls the torque that drives the storage roll 30 and the torque that drives the protective raw roll 42, so that the tension applied to the supplied protective raw fabric 48 is more appropriate. It is possible to further prevent the breakage of the protective raw fabric 48 and the generation of wrinkles during the transport of the protective raw fabric 48. The torque for driving the storage roll 30 and the protective raw roll 42 may be adjusted by changing the ratio of the number of gear teeth of the power transmission mechanism such as the gear described above. . When only the storage roll 30 is driven by the drive unit 70, the protective raw fabric 48 may be unwound from the protective raw roll 42 in synchronization with the rotation of the storage roll 30. .

  Further, as shown in FIG. 1, the transport mechanism 60 can tilt a part of the transport surface by operating a movable transport unit 62 provided as a part of the transport mechanism 60. Yes. More specifically, the movable conveyance unit 62 provided as a part of the conveyance mechanism 60 is a normal conveyance position (indicated by a solid line in FIG. 1) for conveying a sheet medium from the right side to the left direction in FIG. And a storage conveyance position (indicated by a two-dot chain line in FIG. 1) at which a sheet medium can be delivered to the tributary conveyance unit 50 described later (ie, a direction orthogonal to the paper surface in FIG. 1). It can be swung around a shaft 64 extending to the center (see the arrow in FIG. 1). As a result, when the movable transport unit 62 is at the normal transport position, the sheet medium transported from the previous process by the transport mechanism 60 can be transported to the subsequent process. Further, when the movable transport unit 62 is in the storage transport position, the single-sheet medium transported from the previous process by the transport mechanism 60 can be delivered to the tributary transport unit 50 of the single-sheet medium storage device 1. ing.

  In addition, the angle at which the movable conveyance unit 62 is inclined may be determined by the control unit 80 based on the inclination angle of the tributary conveyance unit 50. In this case, the inclination angle of the movable conveyance unit 62 can be optimized according to the inclination angle of the tributary conveyance unit 50, and the single-wafer medium can be transferred to the tributary conveyance unit 50 more smoothly. It is like that. Then, the sheet medium delivered to the tributary transport unit 50 is wound around the outer peripheral surface of the storage roll 30 together with the protective fabric 48 so that the sheet medium is stored in the storage roll 30. ing.

  Further, the inclination angle of the tributary transport unit 50 is determined by the control unit 80 based on the outer diameter of the storage roll 30 and the amount of the protective raw fabric 48 wound around the storage roll 30. Thereby, since the inclination angle of the tributary transport unit 50 can be set to an angle suitable for the outer diameter of the outermost peripheral surface of the protection raw fabric 48 wound around the storage roll 30 (see FIGS. 3 and 4), The sheet medium can be stored more smoothly.

  In addition, by using a non-contact sensor or the like to measure the distance between the sensor and the outermost peripheral surface of the protective raw fabric 48 wound around the storage roll 30 as needed, the protective base wound around the storage roll 30 is measured. A change in the length in the radial direction of the anti-48 may be detected, and the inclination angle of the tributary transport unit 50 may be adjusted by the control unit 80 based on the detected information. In this case, since the inclination angle of the tributary transport unit 50 can be made more appropriate, the single-sheet medium can be more smoothly stored in the storage roll 30.

  Note that the tributary transport unit 50 may be provided in the single-sheet medium storage device 1 with its position and inclination angle being constant. Also in this case, the sheet medium conveyed from the previous process by the conveyance mechanism 60 can be received by the tributary conveyance unit 50, and the received sheet medium can be conveyed to the storage roll 30.

  Further, the conveyance of the sheet medium to the sheet medium storage device 1 is not limited to a mode in which the movable conveyance unit 62 provided as a part of the conveyance mechanism 60 is performed. For example, like the single-sheet medium storage device 1a according to the modification shown in FIG. 5, the conveyance mechanism 60a removes the single-sheet medium from the conveyance path at the normal time (that is, a state where no trouble or the like occurs in the subsequent process). It may be configured to have a branching member 66 (for example, a branching claw) for branching to the branching conveyance unit 52. Such a branching member 66 is normally in a normal transport position indicated by a solid line in FIG. 5, and when the sheet-fed medium transported from the previous process by the transport mechanism 60 is branched to the branch transport unit 52, The shaft rotates about the extending axis to a branch conveyance position indicated by a two-dot chain line in FIG. In this case, the single-sheet medium branched so as to be transported on the branch transport unit 52 by the branch member 66 can be stored in the storage roll 30 connected to the branch transport unit 52.

  Next, the flow of the storing operation of the sheet medium transported by the transport mechanism 60 using the sheet medium storage device 1 of the present embodiment will be described. As described above, in the state where there is no trouble in the post-process or the like, the movable conveyance unit 62 is in the normal conveyance position (indicated by a solid line in FIG. 1), and the single-sheet medium is conveyed from the right side to the left side in FIG. It has come to be.

  First, as preparations for operating the single-sheet medium storage device 1, a storage roll 30 having an outer diameter corresponding to the thickness, material, processing state, etc. of the single-sheet medium conveyed on the line in advance, and the sheets to be stored A protective film 48 (for example, polyethylene terephthalate (PET) film) made of a material suitable for protecting the leaf medium is prepared.

  Next, the prepared storage roll 30 is attached to the base 20 so as to be detachable and rotatable. And by attaching the front-end | tip part of the protection raw fabric 48 to the outer surface of the storage roll 30, when the storage roll 30 is driven, the protection original fabric 48 is wound around the storage roll 30. The inclination angle of the tributary transport unit 50 is adjusted when preparing the operation of the apparatus 1 as described above, but is adjusted when power is supplied to the movable transport unit 62 and the like, which will be described later. It may be. Further, when no trouble occurs in the post-process or the like, the single-sheet medium storage device 1 is in a standby state in this state.

  In such a standby state, when a trouble that has occurred in a subsequent process is detected, the movable conveyance unit 62 is tilted by the control unit 80 and the conveyance path of the single-sheet medium is switched. Power is supplied to the drive unit 70 that drives the protective film roll 42. Here, the conveyance speed of the sheet medium by the tributary conveyance unit 50 is controlled by the control unit 80 so as to be substantially the same as the conveyance speed of the sheet medium conveyed from the previous process. Further, the driving torque of the storage roll 30 and the driving torque of the protective raw fabric roll 42 are controlled by the control unit 80 as described above, whereby the tension is adjusted so that the protective raw fabric 48 is not broken or wrinkled. Note that the inclination angle of the tributary conveyance unit 50 and the movable conveyance unit 62 at this time is an inclination angle suitable for the size of the outer diameter of the storage roll 30, as shown in FIG. The leaf medium is stored smoothly.

  Next, the sheet medium transported by the transport mechanism 60 is tilted with respect to the horizontal direction (i.e., from the transport mechanism 60 that transports the sheet medium in the horizontal direction (i.e., the left-right direction in FIG. 1)). The sheet is transferred to the movable conveyance unit 62 that conveys the sheet medium in the lower left direction in FIG. 1, and is further transferred from the movable conveyance unit 62 to the tributary conveyance unit 50. Then, the sheet medium conveyed to the storage roll 30 by the tributary conveyance unit 50 abuts the upper portion of the outer surface of the storage roll 30 around which the protective raw fabric 48 is wound, with the surface thereof being in contact with the protective raw fabric 48. .

  Next, the sheet medium that has come into contact with the upper portion of the outer surface of the storage roll 30 is wound around the storage roll 30 together with the protective fabric 48 in a state where the pressing force from the nip roll 46 is applied. Such a sheet-sheet medium storing operation is continued until a trouble in a subsequent process is solved, and then the storing operation is stopped while maintaining the tension applied to the protection raw fabric 48. As described above, the control unit 80 controls the inclination angles of the movable conveyance unit 62 and the tributary conveyance unit 50 based on the amount of the protection raw fabric 48 wound. The angles of the movable conveyance unit 62 and the tributary conveyance unit 50 after the medium is stored have an inclination angle different from the time point in FIG. 3 when the storage of the single-sheet medium is started, for example, as shown in FIG. Become.

  According to the single-sheet medium storage device 1 configured as described above, as described above, the storage roll 30 that rotates about the shaft 32 and the outer peripheral surface of the storage roll 30 are branched from the transport mechanism 60. And a protective raw material supply unit 40 for supplying a belt-shaped protective raw material 48 that is wound together with the sheet medium. Therefore, the sheet space medium branched from the transport mechanism 60 is wound around the storage roll 30 by the protection raw fabric 48, and the space occupied by the apparatus can be saved. Can be stored continuously.

  The single-sheet medium storage device according to the present embodiment is not limited to the above-described mode, and various changes can be made.

  For example, the tributary conveyance unit 50 including a roller conveyor is not limited to a configuration in which the diameters of the respective rollers are the same. For example, when the diameter of the roller at the left end of the tributary transport unit 50 shown in FIG. 1 is larger than that of the other rollers, the single-wafer medium and the protective raw fabric 48 are more reliably in contact with the roller. Therefore, the sheet medium can be stored in the storage roll 30 in a more stable state.

  Further, as the protective raw fabric 48 used when storing the single-wafer medium, a surface whose surface is knurled may be used. In this case, as compared with the case where the protective raw fabric 48 whose surface is not knurled is used, the protective raw fabric 48 is misaligned or wound when the protective raw fabric 48 is wound by the storage roll 30. Looseness can be further prevented.

  Moreover, the protection raw fabric supply part 40 is not limited to the aspect comprised from the protection raw fabric roll 42, the protection raw fabric guide roll 44, and the nip roll 46 as mentioned above. It is sufficient that the belt-shaped protection raw fabric 48 can be supplied to the storage roll 30 and that the wrinkle is not generated when the protection raw fabric 48 is wound around the storage roll 30.
