The core body 61 has the same shape in the axial direction parallel to its central axis, except for the concave portions 611 to 611 . With respect to the recesses 611 to 611, the second recesses 6112, 6112 are symmetrical to the first recesses 6111, 6111, which will be described later, with respect to the imaginary plane orthogonal to the center axis at the center of the core body 61 in the axial direction. Above, it is formed at a position shifted by 90° in the circumferential direction of the core 61 . Such a core body 61 can be attached to the outer circumference of the support shaft 31 from one end side of the core body 61 and can also be attached from the other end side of the core body 61 .

A wrapping material 62 can be wound around the outer peripheral portion of the core 61 . The outer diameter dimension of the core body 61 is constant in the axial direction of the core body 61 . There is no step on the outer circumference of the outer circumference of the core body 61 . Therefore, even if the packaging material 62 is wound around the outer circumference of the core body 61, the packaging material 62 does not have a stepped mark.

At least one concave portion 611 is formed in the inner peripheral portion of the core body 61 . In this embodiment, a plurality of recesses 611 are formed. Each recess 611 is recessed radially outward. Each recess 611 of this embodiment is a substantially hemispherical recess. That is, the shape of each recess 611 is a circular recess when viewed in the radial direction. Also, the protruding portion 311 of the support shaft 31 is fitted into each recess 611 . In the present embodiment, the plurality of recesses 611 to 611 include a plurality of (specifically, two) first recesses 6111 located at one end of the core body 61, and at the other end of the core body 61. A plurality of (specifically, two) second recesses 6112, 6112 located are included. It should be noted that the recess 611 can also be formed only at one end or the other end of the core body 61 . It can also be formed in the center in the axial direction. The number of the first recesses 6111 is the same as the number of the base-end-side projections 3111 on the support shaft 31 . The number of the second recesses 6112 is the same as the number of the distal end side protrusions 3112 on the support shaft 31 . However, depending on the combination of the support shaft 31 and the core 61, the number of recesses 6111 and 6112 may be greater than the number of protrusions 3111 and 3112, and there may be recesses 6111 and 6112 that do not fit.

Each first concave portion 6111 is fitted with each base end side projecting portion 3111 of the support shaft 31 when the core body 61 is mounted on the outer periphery of the support shaft 31 from one end side of the core body 61 . On the other hand, when the core body 61 is attached from the other end side of the core body 61 , it is fitted with each tip end side projecting portion 3112 of the support shaft 31 .

The two first recesses 6111 are arranged with an angular interval in the circumferential direction of the core body 61 . The first recesses 6111 are provided at equal angular intervals in the circumferential direction of the core body 61 . In this embodiment, two first recesses 6111, 6111 are provided at intervals of 180° in the circumferential direction of the core body 61. As shown in FIG. When the core body 61 is viewed from one end side, the angular position of one specific first concave portion 6111 in the circumferential direction of the core body 61 is used as a reference (this is also referred to as the angular position reference for the core body 61 in the following description). ) is 0°, the angular position of the other first concave portion 6111 is 180°. This angular positional relationship is the same as the angular positional relationship between the two base end side projections 3111 and 3111 on the support shaft 31 .

Each of the second recesses 6112 is fitted to each of the distal end side protrusions 3112 of the support shaft 31 when the core 61 is attached to the outer circumference of the support shaft 31 from one end side of the core 61 . On the other hand, when the core body 61 is attached from the other end side of the core body 61 , each base end side projecting portion 3111 of the support shaft 31 is fitted.

The two second recesses 6112 are arranged with an angular interval in the circumferential direction of the core body 61 . The second recesses 6112 are provided at equal angular intervals in the circumferential direction of the core 61 . In this embodiment, the two second recesses 6112, 6112 are provided at intervals of 180° in the circumferential direction of the core 61. As shown in FIG. Moreover, in this embodiment, in the circumferential direction of the core 61, each of the two second recesses 6112, 6112 is arranged to be shifted by 90° with respect to each of the two first recesses 6111, 6111. there is When the core 61 is viewed from one end side, if the angular position of one specific first recess 6111 in the circumferential direction of the core 61 is 0°, the angle of each of the two second recesses 6112, 6112 is The positions are 90° and 270°. This angular position relationship is the same as the angular position relationship between the two distal end side projecting portions 3112 and 3112 on the support shaft 31 , as is the case with each first recess 6111 . Due to the arrangement of the first recess 6111 and the second recess 6112 , the support shaft 31 can stably hold the core body 61 .

Each recess 611 is formed so that the innermost paper sheet 61S is not broken. As shown in FIG. 4, the paper sheet 61S positioned in each concave portion 611 is in a curved state because the fibers of the paper are in close contact with each other due to the compression, and the thickness of each layer is thinner than that of the surrounding portion. It is Since the innermost paper sheet 61S is not broken, the ends of the paper fibers forming the paper sheet 61S are less likely to be exposed to the recesses 611 . Therefore, paper dust is less likely to be generated from each concave portion 611 .

Paper dust prevention layers 612 are provided on both axial end faces of the core body 61 . The paper dust prevention layer 612 is a coating layer made of resin, for example. The paper dust prevention layer 612 can prevent packaging troubles caused by paper dust adhering to the packaging material 62 . The method of forming the paper dust prevention layer 612 is not particularly limited. Moreover, it can be formed by immersing both ends of the core body 61 (semi-finished product) in resin (so-called "dobuzuke"). By providing the paper dust prevention layer 612, it is possible to effectively prevent the generation of paper dust due to tearing of the ends of the paper fibers exposed at the edges of the stacked paper sheets 61S.

-Manufacturing method of core and wound body-
Next, a method for manufacturing the core body 61 will be described. This manufacturing method includes a forming process, a cutting process, a recess forming process, and a paper dust prevention layer forming process. Steps other than these can also be added. In the forming process, the paper sheets 61S are radially laminated to form a cylindrical shape. By manufacturing a semi-finished product of the core body 61 through such a molding process, the core body 61 can be easily manufactured. A known paper tube manufacturing method can be applied to the molding step. Specifically, an adhesive is applied to at least one surface of the paper sheet 61S, and the paper sheet 61S is wound so as to sandwich the adhesive layer, thereby laminating in the radial direction until the thickness dimension reaches a predetermined dimension. go. In a general paper tube manufacturing method, the paper sheet 61S is spirally wound, but the paper sheet 61S is similarly wound in the core body 61 of the present embodiment. In the cutting step, the paper tube formed in the forming step is axially cut into predetermined dimensions. In the concave portion forming step, a pressing tool 7 (indicated by a two-dot chain line in FIG. 4) such as a metal stamping die is pressed against the inner peripheral surface of the molded cylindrical body to press it radially outward. At least one concave portion 611 that is concave radially outward is formed in the inner peripheral portion of the cylindrical body formed in the molding process. The core body 61 is formed through the above steps.

In addition, it is not essential to implement all the said each process. For example, it is also possible to obtain a paper tube that is generally distributed without performing the forming process, and to perform the cutting process and the recess forming process on the paper tube. Furthermore, it is also possible to obtain a cut paper tube and perform only the recess forming process on the paper tube.

Furthermore, a method for manufacturing the wound body 6 will be described. The method for manufacturing the wound body 6 includes a winding step of winding a wrapping material 62 as a long wound material around the outer peripheral surface of the core body 61 . In the winding process, the packaging material 62 is wound so as to overlap with each other in the radial direction.

Moreover, in the case of a sheet shape, it may be a net shape with spaces penetrating in the thickness direction. Also, the winding may be a combination of a seal and a release sheet.

The recessed portion 611 of the core body 61 is formed by pressing in the above-described embodiment so as not to break the innermost paper sheet 61S. However, the invention is not limited to this, and the recess 611 can also be formed by cutting or cutting. Alternatively, a through hole may be provided in advance in the paper sheet 61S before stacking, and the concave portion 611 may be formed along with the stacking. Further, the recess 611 may be a notch formed axially from the end face of the core 61 . In addition, the inner surface of the recess 611 can be reinforced by providing a layer similar to the paper dust prevention layer 612 (such as a coating layer made of resin) in the recess 611 .

The core body 61 may be provided with identification means for identifying the wound body 6 in a device for handling a long wound body such as a medicine packaging device.
