FIG. 1 is a schematic configuration side view of a wrapping paper roll body 1 according to an embodiment of the present invention. FIG. 2 is a schematic cross-sectional view showing a cross section taken along line AA in FIG. The packaging paper roll body 1 according to the present invention is, for example, a packaging paper roll body 1 mounted on a rotatable support shaft body 11 included in a medicine packaging machine 10 as shown in a cross-sectional view of FIG. More specifically, it is a wrapping paper roll body 1 that is loaded and used for dispensing and packaging a medicine to a patient in a hospital or a pharmacy.

  As shown in FIGS. 1 and 2, the wrapping paper roll body 1 includes a roll paper core tube 2 in which a wrapping paper 5 is wound around an outer peripheral surface, a cylindrical body 3, and friction engagement means 4. And. As the wrapping paper 5 wound around the outer peripheral surface of the roll paper core tube 2, various wrapping papers 5 conventionally used in medicine dispensing and packaging such as glassine paper and cellopoly paper can be used. The roll paper core tube 2 is a cylindrical member, and can be formed of, for example, a synthetic resin member or a cardboard material.

  The cylindrical body 3 is a member that is configured to be inserted into the roll paper core tube 2 with the axis line aligned, and is a member that is fitted and fixed onto a support shaft body 11 provided in the medicine packaging machine 10. The inner diameter of the cylindrical body 3 is formed so as to be substantially the same as the outer diameter of the support shaft body 11 included in the medicine packaging machine 10, and the cylindrical body 3 is configured to be slidable on the support shaft body 11. Has been. The outer diameter of the cylindrical body 3 is configured to be smaller than the inner diameter of the roll paper core tube 2 described above, and the inner peripheral surface of the roll paper core tube 2 and the outer seed surface of the cylindrical body 3 A gap is formed between them. The cylindrical body 3 is formed with a fixing means 31 for fixing on the support shaft body 11 provided in the medicine packaging machine 10. Various means can be adopted as the fixing means 31. For example, as shown in FIG. 3, a ferromagnetic plate that is attracted to the permanent magnet 12 provided on the support shaft 11 is adopted as the fixing means 31. The ferromagnetic plate 31 can be configured by disposing it at the end of the cylindrical body 3. With such a configuration, the cylindrical body 3 can be fixed on the support shaft body 11 by the attractive force between the ferromagnetic plate 31 on the cylindrical body 3 side and the permanent magnet 12 on the support shaft body 11 side, and the support shaft body With the rotation of 11, the cylindrical body 3 can be smoothly rotated.

  Examples of the material constituting the cylindrical body 3 include various materials such as a synthetic resin material and a metal material. Further, as the cylindrical body 3, the core tube provided in the conventionally known roll paper described in the background art section above, that is, the core remaining on the support shaft body 11 when the roll paper is all used up. The tube (existing core) may be reused.

  The friction engagement means 4 is a member for allowing both the roll paper core tube 2 and the cylindrical body 3 to rotate. The friction engagement means 4 is wound around the outer peripheral surface of the cylindrical body 3, The elastic ring member 41 is interposed between the outer peripheral surface of the cylindrical body 3 and the inner peripheral surface of the roll paper core tube 2. The elastic ring member 41 is wound around the outer peripheral surface of the cylindrical body 3 so as to be movable along the axial direction of the cylindrical body 3. As such an elastic ring member 41, a generally available rubber band or an O-ring made of rubber can be preferably exemplified. As the cross-sectional shape of the elastic ring member 41, various shapes such as a quadrangle, a circle, and an ellipse can be adopted. Moreover, as the elastic ring member 41, you may use the thing of the flat form whose thickness is smaller than a width | variety. In addition, the thickness of the elastic ring member 41 is set to be larger than a gap dimension formed between the inner peripheral surface of the roll paper core tube 2 and the outer peripheral surface of the cylindrical body 3. That is, the outer diameter D (see FIG. 4) of the cylindrical body 3 including the elastic ring member 41 when the elastic ring member 41 is wound around the outer peripheral surface of the cylindrical body 3 is the roll paper core tube 2. Set to be larger than the inner diameter. Further, when the cylindrical body 3 around which the elastic ring member 41 is wound around the outer peripheral surface is inserted into the roll paper core tube 2 with its axis line aligned, the elastic ring member 41 is compressed and deformed. The thickness of the elastic ring member 4141 is set so that the cylindrical body 3 around which the ring member 41 is wound has a thickness enough to be inserted into the roll paper core tube 2.

  A method of using the packaging paper roll body 1 having such a configuration will be described below. First, as shown in FIGS. 5A and 5B, the cylindrical body 3 of the packaging paper roll body 1 is fitted on the support shaft body 11 in the paper feeding unit of the medicine packaging machine 10 to wrap the packaging paper roll body 1. It is fixed on the support shaft 11. At this time, the cylindrical body 3 is integrally fixed to the support shaft body 11 by the action of the fixing means 31 provided in the cylindrical body 3. Next, by rotating the support shaft 11 of the medicine packaging machine 10, the medicine such as powder is packaged by the packaging paper 5 while the packaging paper 5 wound around the roll paper core tube 2 is fed out for a predetermined length. Here, since the friction engagement means 4 including the elastic ring member 41 is interposed between the roll paper core tube 2 and the cylindrical body 3, the cylindrical body 3 can be rolled without being idle. The tube 2 can be rotated.

  When the packaging paper 5 wound around the roll paper core tube 2 is used up by repeating the packaging of the medicine, as shown in FIGS. 5 (c) and 5 (d), the used roll paper core tube 2 is tubed. The sheet 3 is pulled out and separated and replaced with a new roll paper core tube 2 around which the wrapping paper 5 is wound. Here, an elastic ring member 41 is interposed between the roll paper core tube 2 and the cylindrical body 3. The elastic ring member 41 is simply wound around the outer peripheral surface of the cylindrical body 3. The elastic ring member 41 rolls on the outer peripheral surface of the cylindrical body 3 while maintaining the ring shape when the roll paper core tube 2 is pulled out from the cylindrical body 3 because it is only disposed. It will be.

  After the used roll paper core tube 2 is removed from the cylindrical body 3, the cylindrical body 3 is inserted into a new roll paper core tube 2 around which the wrapping paper 5 is wound. The roll paper core tube 2 is installed on the outer peripheral surface of 3. The cylindrical body 3 into which the new roll paper core tube 2 is inserted corresponds to the existing core described in the background art. When installing the roll paper core tube 2 on the outer peripheral surface of the cylindrical body 3, for example, as shown in FIG. 5 (e), one end of the cylindrical body 3 on the insertion side of the roll paper core tube 2 is used. The elastic ring member 41 is wound and arranged on the outer peripheral surface near the portion. Next, as shown in FIG. 5 (f), the roll paper core tube 2 is pushed in the axial direction of the cylindrical body 3 while being inserted into one end of the cylindrical body 3 into the roll paper core tube 2. At this time, the elastic ring member 41 wound around the outer peripheral surface of the cylindrical body 3 is sandwiched between the inner peripheral surface of the roll paper core tube 2 and the outer peripheral surface of the cylindrical body 3 and is compressed and deformed. As the core tube 2 is pushed in, it moves on the outer peripheral surface of the cylindrical body 3 while maintaining a ring shape.

  By setting a new roll paper core tube 2 at a predetermined position with respect to the cylindrical body 3, the replacement operation of the roll paper core tube 2 is completed (the state shown in FIG. 5B). By rotating the support shaft body 11, the packaging operation of the powder medicine and the like is continued while the packaging paper 5 wound around the roll paper core tube 2 is fed out.

  As described above, the wrapping paper roll body 1 according to the present invention is configured to include the friction engagement means 4 so that both the roll paper core tube 2 and the cylindrical body 3 can rotate, and the friction engagement means. 4 is an elastic ring member 41 wound around the outer peripheral surface of the cylindrical body 3 and interposed between the outer peripheral surface of the cylindrical body 3 and the inner peripheral surface of the roll paper core tube 2. Is wound around the outer peripheral surface of the cylindrical body 3 so as to be movable along the axial direction of the cylindrical body 3, so that the roll paper core tube 2 is attached to and detached from the cylindrical body 3. When performing, the elastic ring member 41 (friction engaging means 4) can be moved by rolling on the outer peripheral surface of the cylindrical body 3, and the friction of the friction engaging means 4 when the roll paper core tube 2 is detached. The force can be reduced, and the roll paper core tube 2 can be replaced very smoothly.

  In addition, in a state where the roll paper core tube 2 is inserted through the cylindrical body 3 and set at a predetermined position, the elastic ring member 41 (friction engagement means 4) is a circumferential direction that is the rotational direction of the cylindrical body 3. The cylindrical body 3 and the roll paper core tube have excellent frictional resistance when the cylindrical body 3 fixed integrally with the support shaft body 11 of the medicine packaging machine 10 is rotated. 2 can be given. As a result, it is possible to effectively prevent the cylindrical body 3 from spinning around the roll paper core tube 2, and the roll paper core tube 2 and the cylindrical body 3 can be rotated together.

  Further, when the roll paper core tube 2 is set on the cylindrical body 3, the wrapping paper roll body 1 according to the present invention has one of the cylindrical bodies 3 on the insertion side of the roll paper core tube 2 as described above. The elastic ring member 41 is wound on the outer peripheral surface near the end, and the roll paper core tube 2 is inserted into the roll paper core tube 2 while inserting the one end of the cylindrical body 3 into the axial direction of the cylindrical body 3. By pushing it into When the roll paper core tube 2 is pushed in, the elastic ring member 41 interposed between the cylindrical body 3 and the roll paper core tube 2 is twisted while maintaining the ring shape. It rolls on the surface and moves. As a result, at the stage of completing the setting of the roll paper core tube 2 to the cylindrical body 3, the elastic ring member 41 has a large number of constricted portions 41a due to twisting along its circumferential direction as shown in the schematic view of FIG. Will be formed. That is, for example, as the elastic ring member 41, when a flat shape whose thickness is smaller than the width is used, a portion between one constricted portion 41a and another constricted portion 41a adjacent to the constricted portion. Since the thickness of 41b is increased by twisting, the outer peripheral surface of the cylindrical body 3 and the inner peripheral surface of the roll paper core tube 2 are strongly pressed. It is possible to more effectively prevent the shape body 3 from idling.

  Moreover, according to the wrapping paper roll body 1 according to the present invention, when the wrapping paper 5 wound around the roll paper core tube 2 is used up, a new roll paper core tube 2 can be inserted into the cylindrical body 3. Therefore, the cylindrical body 3 provided with the fixing means 31 can be reused any number of times.

  The wrapping paper roll body 1 according to the present invention has been described above, but the specific configuration is not limited to the above embodiment. For example, FIG. 2 shows a configuration including a single elastic ring member 41 that is the friction engagement means 4, but is not particularly limited to such a configuration, and the friction engagement means 4 is constituted by a plurality of elastic ring members 41. May be configured.

  Moreover, in the said embodiment, you may form the resistance production | generation part 6 which provides resistance with respect to the movement of the elastic ring member 41 in the internal peripheral surface of the roll paper core pipe 2. FIG. For example, as shown in the cross-sectional view of FIG. 7, the resistance generator 6 can be configured by a protrusion 61 that protrudes from the inner peripheral surface of the roll paper core tube 2. The protruding height of the protrusion 61 is configured to be slightly smaller than the thickness of the elastic ring member 41, for example. Further, the number of the protrusions 61 may be singular or plural. In addition, as the shape of the protrusion 61, various shapes such as a dome shape, a conical shape, and a prismatic shape can be adopted. Further, the protrusion 61 may have a ring shape extending along the circumferential direction of the inner peripheral surface of the roll paper core tube 2. Further, the protrusion 61 may be formed in a net shape by providing a net-like member on the inner peripheral surface of the roll paper core tube 2. Further, when the resistance generating unit 6 is configured by a plurality of protrusions 61, the protrusions 61 may be arranged in the axial direction of the roll paper core tube 2. By providing such a resistance generation unit 6, it is possible to control the setting position of the elastic ring member 41 when setting the roll paper core tube 2 on the cylindrical body 3. That is, after the elastic ring member 41 comes into contact with the resistance generation unit 6 (projection body 61) as the roll paper core tube 2 is pushed into the cylindrical body 3, the elastic ring member 41 is connected to the resistance generation unit 6. It moves while being pushed by the (projection 61). As a result, the elastic ring member 41 can be fastened in the vicinity of the region where the resistance generator 6 is formed when the roll paper core tube 2 is completely attached to the cylindrical body 3. In addition, a part of the elastic ring member 41 can be sandwiched between the protrusion 61 and the outer peripheral surface of the cylindrical body 3, and as a result, the elastic ring member 41 is displaced when using the medicine packaging machine 10. It becomes possible to suppress that.

  For example, a plurality of dome-shaped protrusions 61 (resistance generation unit 6) are provided at predetermined intervals along the circumferential direction of the inner peripheral surface of the roll paper core tube 2 in the central region in the longitudinal direction of the roll paper core tube 2. When configured to be formed, the elastic ring member 41 can be controlled so as to remain in the central region in the longitudinal direction of the roll paper core tube 2 at the stage of completing the setting of the roll paper core tube 2 with respect to the cylindrical body 3. By configuring the elastic ring member 41 so as to remain in the central region in the longitudinal direction of the roll paper core tube 2, it is possible to suppress unstable behavior during rotation of the wrapping paper roll body 1.

  Moreover, you may form the protrusion 61 (resistance production | generation part 6) in the one side predetermined range of the internal peripheral surface of the roll paper core pipe 2, as shown in FIG. In FIG. 8, the protrusion 61 (resistance generation unit 6) is formed in the one side region 22 on the inner peripheral surface and in a region from one end of the cylindrical body 3. 8A is a schematic cross-sectional view of the wrapping paper roll body 1, and FIG. 8B is a side view seen from the direction of arrow B in FIG. 8A. In the case of adopting such a configuration, one elastic region member 41 that moves while maintaining a ring shape on the outer peripheral surface of the cylindrical body 3 and one side region 22 on the inner peripheral surface of the roll paper core tube 2 The non-uniform resistance can be imparted with the other one-side region 23, and between the one-side region 22 on the inner peripheral surface of the roll paper core tube 2 and the other one-side region 23, 2 in the figure. As indicated by the dotted line, the elastic ring member 41 can be disposed so as to be obliquely connected. In other words, the elastic ring member 41 can be disposed along the longitudinal direction of the cylindrical body 3 on the outer peripheral surface of the cylindrical body 3, and the backlash of the roll paper core tube 2 with respect to the cylindrical body 3 is effectively suppressed and stabilized. Can be set automatically.

  Further, as shown in FIG. 9, the protrusion 61 (resistance generating unit 6) is connected to a predetermined region (one one-side predetermined region) in one side region 22 on one inner peripheral surface of the roll paper core tube 2, and the other It may be formed in each of the predetermined regions (other one-side predetermined regions) in the one-side region 23 so that one one-side predetermined region and the other one-side predetermined region do not face each other. In the case of adopting such a configuration, as shown by a two-dot chain line in the drawing, the one side predetermined region on the inner peripheral surface of the roll paper core tube 2 and the other side predetermined region are connected obliquely. The elastic ring member 41 can be sandwiched between the protrusion 61 formed in each of the two regions and the outer peripheral surface of the cylindrical body 3 while the elastic ring member 41 is disposed on the When the packaging machine 10 is used, the posture of the elastic ring member 41 can be maintained in a state (an oblique state) indicated by a two-dot chain line in the drawing.

  Further, instead of configuring the resistance generating unit 6 by the protrusions 61, it may be formed as a groove formed along the circumferential direction of the inner peripheral surface of the roll paper core tube 2. Even in the case where the resistance generating unit 6 is configured by a groove, the same effect as described above can be obtained. The depth of the groove is such that, even when the elastic ring member 41 is accommodated in the groove, the elastic ring member 41 can rotate both the roll paper core tube 2 and the cylindrical body 3 by its frictional resistance. Set the depth to the extent that Further, the number of grooves formed may be singular or plural.
