The packaging material 62 is conveyed in the longitudinal direction (direction of arrow F in the figure). The packaging material 62 is wound around the outer periphery of the core body 61 (specifically, the core body in the core body 61) to form a roll-shaped wound body (wrapping material roll) 6. That is, the winding body 6 is formed by winding a long sheet-shaped packaging material 62. In the winding body 6, the packaging material 62 is wound around the outer circumference of the core body 61 in a state of being half-folded at the center in the width direction (short direction). The packaging material 62 is unwound from the winding body 6. The drug packaging device 1 wraps the drug using the packaging material 62 unwound from the winding body 6. The packaging unit 2 in the drug packaging device 1 is located in the order of the packaging material supply unit 3, the packaging material transport unit 4, and the packaging body forming unit 5 from the upstream side to the downstream side in the transport direction of the packaging material 62. These will be described below. For convenience, the packaging material supply unit 3 will be described later.

-Packaging material carrier-
The packaging material transport unit 4 transports the packaging material 62 in the longitudinal direction and supplies the packaging material 62 to the packaging body forming portion 5 on the downstream side in the transport direction. The packaging material transport unit 4 mainly includes a tension adjusting mechanism 41 and a folding bar 42. The tension adjusting mechanism 41 is a mechanism for adjusting the tension by bridging the packaging material 62 between a plurality of rollers 411 to 413 in which the distance between the shafts varies so as to be folded back. In the tension adjusting mechanism 41 of the present embodiment, for example, the position of the axis moves along the two fixed rollers 411, 412 in which the position of the axis is immovable and the curved elongated hole 311 opened on the surface of the base 31. One dancer roller 413 is combined. The folding bar 42 changes the conveying direction of the packaging material 62, which is conveyed upward from the tension adjusting mechanism 41, diagonally downward. The packaging material transport unit 4 may be provided with, for example, a printing unit 43 for printing drug prescription information or the like on the surface of the packaging material 62.

-Package forming part-
The packaging body forming portion 5 is a portion that supplies a chemical to the packaging material 62 according to the prescription and adheres the packaging material 62 to wrap each package. The packaging body forming portion 5 mainly includes a triangular plate 51, a hopper 52, and a packaging material adhesive portion 53. The triangular plate 51 is located on the downstream side of the folding bar 42 in the transport direction, and pushes open one side and the other side of the packaging material 62 in a half-folded state in the width direction, thereby forming a V-shaped cross section in the longitudinal direction. It is the part to be formed. In the hopper 52, a part of the lower portion 522 formed by reducing the cross-sectional area as compared with the upper portion 521 is inserted into the space 62S having a V-shaped cross section in which the packaging material 62 is pushed open by the triangular plate 51. A drug supply mechanism (not shown) provided above the hopper 52 supplies the drug supplied according to the prescription to the packaging material 62 via the inside of the hopper 52. The packaging material adhesive portion 53 is a portion that adheres the packaging material 62 to which the drug has been supplied so as to partition the packaging material 62 one by one by heat-welding the packaging material 62 or the like. In addition to this, the packaging body forming portion 5 may be provided with, for example, a perforation forming portion (not shown) for forming a perforation for facilitating cutting in the packaging material 62 bonded by the packaging material adhesive portion 53. it can.

-Packaging material supply section-
The packaging material supply unit 3 is a portion that sends the packaging material 62 to the packaging material transport unit 4 and subsequent units. The winding body 6 is arranged in the packaging material supply unit 3 so as to be rotatable in the circumferential direction. As the winding body 6 rotates, the packaging material 62 is pulled out from the winding body 6 in the longitudinal direction.

As shown in FIG. 2, the packaging material supply unit 3 includes a base 31 and a support shaft 32. As described above, the base 31 is also provided with a part of the packaging material conveying portion 4 (tension adjusting mechanism 41). The base 31 is fixedly provided in the packaging material supply unit 3. The support shaft 32 projects from the surface of the base 31 (the surface facing the winding body 6 in the drawing). The support shaft 32 has a substantially columnar shape. The support shaft 32 has a base end portion and a tip end portion. The base end portion of the support shaft 32 is supported by the base 31. The support shaft 32 is rotatably provided with respect to the base 31, and supports the winding body 6. The support shaft 32 is driven by a drive unit such as a stepping motor (not shown) provided inside the base 31, and rotates with respect to the base 31. The rotation of the support shaft 32 is performed in both the pull-out direction and the pull-in direction of the packaging material 62. Further, the support shaft 32 is rotated intermittently in response to the supply of the packaging material 62 to the packaging body forming portion 5. The support shaft 32 projects from the surface of the base 31 toward the tip. The axis of the support shaft 32 extends vertically from the surface of the base 31. In this embodiment, the surface of the base 31 is a vertical surface. The surface of the base 31 may be an inclined surface inclined with respect to the vertical plane, or may be a horizontal plane. The support shaft 32 is cantilevered with respect to the base 31, and the tip of the support shaft 32 is open. Therefore, as shown in FIG. 2, the core body 61 in the winding body 6 is arranged at the axial extension position on the open side of the support shaft 32, and is moved axially from the tip end side to the base end side. As a result, the winding body 6 can be attached to the support shaft 32. A winding body 6 is attached to the support shaft 32 so that it cannot rotate relative to each other.

As shown in FIG. 3, on the surface of the base 31, a lock pin engaging portion 33 with which the tip of the lock pin 351 described later is engaged is formed on a portion of the support shaft 32 facing the base end surface. The lock pin engaging portion 33 has a plurality of protrusions formed on the entire circumference at regular intervals in the circumferential direction. That is, the lock pin engaging portion 33 is located in the circumferential direction on the surface of the base 31, and has a plurality of irregularities. As a result, the recesses 331 and the protrusions 332 arranged in the circumferential direction are alternately formed. The tip of the lock pin 351 provided on the support shaft 32 is positioned in the recess 331 to engage with the recess 331, and the rotation of the support shaft 32 is prevented. In the present embodiment, the recess 331 is a portion between the protrusions 332 and 332 formed on the surface of the base 31. However, on the contrary, the protrusion 332 may be a portion between the recesses 331 and 331 formed on the surface of the base 31, or the recess 331 and the protrusion 332 may be formed on the surface of the base 31. Good. That is, the lock pin engaging portion 33 may have an unevenness with which the tip of the lock pin 351 engages. The box-shaped portion shown in FIG. 3 partially overlapping the lock pin engaging portion 33 is the magnetic sensor 34. The magnetic sensor 34 is a part of the magnetic detection unit and detects the magnetism of a permanent magnet (described later) provided on the support shaft 32. As shown in FIG. 6, a magnetic sensor 32C is also provided inside the tip portion of the support shaft 32 (inner shaft 32i).

As shown in FIGS. 4 and 5, the support shaft 32 in the present embodiment is integrally mounted on the outer periphery of the inner shaft 32i and the inner shaft 32i which is supported by the base 31 and rotates with respect to the base 31. It has a two-part structure with an exterior part 32o. The outer diameter of the outer portion 32o is larger than the outer diameter of the inner shaft 32i. The outer diameter dimension of the exterior portion 32o is set to match the outer diameter dimension of the support shaft 32 described above. Such a two-part structure is, for example, more than the support shaft (corresponding to the inner shaft 32i in the present embodiment) provided in the existing drug packaging device 1 as used in the existing drug packaging device 1. It can be used when mounting the winding body 6 having a core body 61 having a large inner diameter. In this case, the core body 61 having a large inner diameter is mounted on the outer periphery of the exterior portion 32o. In this case, the lock pin engaging portion 33 is formed as, for example, a single annular member, and is provided on the surface of the base 31 by attachment or screwing when the exterior portion 32o is attached to the inner shaft 32i.

Hereinafter, the description of the support shaft 32 in this embodiment is premised on this two-part structure. However, in the newly manufactured drug packaging device 1 and the like, the support shaft 32 can be integrated, and even in this case, the configuration of each part of the support shaft 32 is the same as that of the present embodiment described below. Can be implemented. When the support shaft 32 has an integral structure, there is no distinction between the inner shaft 32i and the outer portion 32o, and the configuration provided in either the inner shaft 32i or the outer portion 32o in the two-part structure is the same as the support shaft 32. It is provided in.

The exterior portion 32o has a tubular shape (or a tubular shape) having a circular shape in the radial cross section. The exterior portion 32o of the present embodiment is divided into two pieces in the radial direction as shown by a solid line extending in the axial direction in FIG. The division is made at an angle of 180 ° in the circumferential direction. That is, the outer shapes of the two pieces are symmetrical (plane-symmetrical) except for fine shapes such as grooves. The two divided pieces are integrated by, for example, screwing. By dividing the exterior portion 32o in this way, there is an advantage that it can be easily attached to the inner shaft 32i. Further, as compared with forming one tubular body, the mold design is easy, so that the manufacturing cost can be reduced.

The exterior portion 32o includes a plurality of magnet holding portions 321 that hold a combination of permanent magnets corresponding to the magnetic detection portions (magnetic sensors 34 and 32C) provided by the packaging material supply unit 3 for identifying the winding body 6. Be prepared. Permanent magnets are arranged in a predetermined number of selected magnet holding portions 321 among the plurality of magnet holding portions 321 (the drawing shows the magnet holding portion 321 in a state where the permanent magnets are not arranged). Specifically, the "identification of the wound body 6" is to identify the material of the packaging material 62. In the plurality of magnet holding units 321, the magnetic detection unit detects and identifies the number of magnet holding units 321 in which the permanent magnets are arranged, the polarity of the permanent magnets, the strength of the magnetic force, and the like. When the material of the packaging material 62 used in the drug packaging device 1 is constant and does not change, the same exterior portion 32o can be used without any problem. If the material of the packaging material 62 is changed, it can be dealt with by replacing it with an exterior portion 32o provided with a permanent magnet of a combination suitable for the packaging material 62 to be changed, or by replacing the permanent magnet. The magnet holding unit 321 is unnecessary for a newly manufactured drug packaging device or a drug packaging device in which the magnetic detection unit is removed or invalidated by modification.

As shown in FIG. 5, a plurality of (4 in this embodiment) alignment protrusions 322 are formed at the base end portion of the support shaft 32 (inner shaft 32i in this embodiment). The plurality of alignment protrusions 322 are provided at a certain distance in the circumferential direction. Each alignment protrusion 322 projects in the outer diameter direction from the outer peripheral surface of the base end portion of the support shaft 32 (inner shaft 32i). Each alignment protrusion 322 extends in the axial direction from the base end of the support shaft 32 (inner shaft 32i) by a predetermined distance in the tip direction. A rod-shaped packaging material breakage detection pin 323 projects in the radial direction from a part of the plurality of alignment protrusions 322 (in this embodiment, every other alignment protrusion 322 in the circumferential direction). The tip of the packaging material breakage detection pin 323 is set to be located outside the diameter of the outer peripheral surface of the core body 61 when the winding body 6 is mounted on the support shaft 32 (see FIG. 6). Further, each of the alignment protrusion 322 provided with the packaging material breakage detection pin 323 and the exterior portion 32o that overlaps the alignment protrusion 322 in the radial direction is a notch portion 324 that penetrates in the radial direction and extends in the axial direction. 325 is provided.

As shown in FIG. 6, the packaging material breakage detection pin 323 is formed on the support shaft 32 (inner shaft 32i) by the urging force of the coil spring 3231 provided inside the support shaft 32 (inner shaft 32i in this embodiment). It is urged toward the tip side (right side in the figure) in the axial direction. When the wound winding body 6 of the packaging material 62 is attached to the support shaft 32, the packaging material shortage detection pin 323 is provided by the packaging material 62 laminated in the radial direction on the outer circumference of the winding body 6. By being pushed out to the side, it is moved to the axial base end side against the spring urging. In the core body 61 of the winding body 6, the portion corresponding to the packaging material breakage detection pin 323 when mounted on the support shaft 32 penetrates in the radial direction and the shaft, as in the case of the inner shaft 32i and the outer portion 32o. A notch 611 extending in the direction is provided. As shown in FIG. 6, the notch portion 611 is arranged so as to coincide with the notch portions 324 and 325 of the support shaft 32 (inner shaft 32i, exterior portion 32o) in the circumferential direction. Therefore, the core body 61 may be rotated in the circumferential direction with respect to the support shaft 32 by the operator in order to align the notch portion 611. When the packaging material 62 is pulled out from the winding body 6 and disappears (when only the core body 61 is formed), the extruding by the packaging material 62 is not performed, so that the spring-urged packaging material breakage detection pin 323 is axially oriented. It moves to the tip side and enters the notch 611 (see FIG. 6). By detecting that the packaging material shortage detection pin 323 has entered the notch portion 611 in this way with a sensor or the like, the packaging material shortage can be detected. By detecting that all the packaging material 62 has been unwound from the winding body 6, for example, the packaging material supply unit 3 can be automatically stopped.

As shown in FIG. 6, an inward displacement regulating portion 326 projects from the outer peripheral surface of the inner shaft 32i. The medial displacement regulating portion 326 is, for example, a spherical protrusion that is urged in the outer diameter direction by a spring provided inside the inner shaft 32i and partly protrudes from the outer peripheral surface of the inner shaft 32i. Further, in the exterior portion 32o, an outer displacement regulating portion 327 is provided at a portion that coincides with the medial displacement regulating portion 326 when mounted on the inner shaft 32i. The outer deviation restricting portion 327 is provided so as to appear and disappear on the outer peripheral surface of the exterior portion 32o. The outer displacement regulating portion 327 is pushed by the medial displacement regulating portion 326 in the out-of-diameter direction so as to project from the outer peripheral surface of the support shaft 32 (exterior portion 32o). The outer deviation regulating portion 327 engages with the stepped portion 612 described later in the core body 61. Therefore, it is possible to prevent the core body 61 from being displaced in the axial direction with respect to the support shaft 32, and the winding body 6 can be reliably mounted on the support shaft 32. When the support shaft 32 has an integral structure, the inner displacement regulating portion 326 and the outer displacement regulating portion 327 can be formed as a single member (in the case of an integrated structure, for example, referred to as a “deviation regulating portion”). This single member is a shaft-shaped member corresponding to the combination of the inner shaft 32i and the outer shaft 32o in the present embodiment.

As shown in FIG. 6, at the base end portion of the exterior portion 32o, an alignment recess 328 is formed at a position corresponding to the alignment protrusion 322 of the inner shaft 32i (when mounted on the inner shaft 32i). .. The alignment recess 328 is recessed in the outer diameter direction on the inner peripheral surface of the exterior portion 32o. The alignment recess 328 is formed with the above-mentioned notch 325 through which the packaging material shortage detection pin 323 penetrates in the radial direction. The cutout portion 325 has a space that penetrates the exterior portion 32o in the radial direction and is open to the base end of the exterior portion 32o. In this space, the packaging material shortage detection pin 323 moves in the axial direction of the support shaft 32. As described above, this movement is performed after the packaging material 62 is pulled out from the winding body 6 and disappears.

As shown in FIGS. 5, 7, and 8, a core body guide groove (or groove portion) 329 is formed on the outer peripheral surface of the support shaft 32 (exterior portion 32o in the present embodiment). When the core body 61 is mounted on the support shaft 32, the support shaft fitting portion 613 protruding from the inner peripheral surface of the core body 61 is fitted into the core body guide groove 329. Due to this fitting, the core body 61 cannot rotate relative to the support shaft 32. That is, when the core body 61 is mounted on the outer periphery of the support shaft 32, the support shaft fitting portion 613 rotates in the circumferential direction of the core body 61 with respect to the support shaft 32 in cooperation with the core body guide groove 329. To prevent.

The core body guide groove 329 is formed in a section of the support shaft 32 (exterior portion 32o) from the tip end to the middle toward the base end side. That is, the core body guide groove 329 extends from the tip end portion of the support shaft 32 toward the base end portion. A part of the link mechanism 35 (pressed portion 3543), which will be described later, is exposed inside the core body guide groove 329. The core body guide groove 329 is the tip end portion of the exterior portion 32o, and the width dimension in the radial view is enlarged in a forward-expanded manner (see FIGS. 7 and 8). Therefore, the support shaft fitting portion 613 of the core body 61 is smoothly introduced and accommodated in the core body guide groove 329. That is, the support shaft fitting portion 613 is guided to the core body guide groove 329 when the core body 61 is attached to and detached from the support shaft 32.

As shown in FIGS. 5, 7, and 8, a link mechanism 35 is provided on the support shaft 32 (exterior portion 32o). The link mechanism 35 is shown as a single unit in FIG. The link mechanism 35 includes a lock pin 351, an extension plate 352, a coil spring 353, and a link body 354.

The lock pin 351 has a rod shape. In the present embodiment, it has a round bar shape and extends linearly along the axial direction of the support shaft 32. The lock pin 351 has a large diameter on the base end side and a small diameter on the tip end side, and has a step 3511. The lock pin 351 extends in the axial direction of the support shaft 32 on the proximal end side of the support shaft 32 (exterior portion 32o). The lock pin 351 is movable in the axial direction on the support shaft 32 (exterior portion 32o). Along with this movement, the lock pin 351 appears and disappears with respect to the end surface (specifically, the base end surface) of the support shaft 32. FIG. 7 is a protruding state, and FIG. 8 is an immersive state.

The extension plate 352 is connected to the tip of the lock pin 351. In the extension plate 352, two rows parallel to each other in the circumferential direction of the support shaft 32 extend in the axial direction of the support shaft 32. Each row is strip-shaped. The lock pin 351 and the extension plate 352 are formed on the same axis, and both move in the axial direction on the support shaft 32 (exterior portion 32o) as an integral moving body (not numbered). The extension plate 352 is formed of an elastic plate-like body such as a steel plate. Each row of extension plates 352 is bent at the tip in a direction opposite to each other. This bent portion is the mounting display unit 3521. The mounting display unit 3521 is colored, for example. The extension plate 352 is movable on the support shaft 32 (exterior portion 32o) along the axial direction of the support shaft 32. The tip surface of the support shaft 32 (exterior portion 32o), which is the tip surface of the extension plate 352, so that the mounting display portion 3521 can be visually recognized from the outside of the support shaft 32 when the extension plate 352 moves to the tip side of the support shaft 32. A display window portion 32A having a space is provided at the extension position on the tip side. By locating the colored mounting display unit 3521 on the display window unit 32A, the lock pin 351 moves to the tip side and escapes from the lock pin engaging portion 33, so that the support shaft 32 can rotate. Can be notified to the worker. The display window portion 32A has a tapered shape, and the mounting display portion 3521, which is divided according to the two rows of the extension plate 352, approaches as the extension plate 352 moves toward the tip end, as shown in FIG. In a state where both sides are in contact with each other to form one surface, the display window portion 32A visibly appears. That is, the mounting display unit 3521 can be moved between the first position which is not visible from the outside of the support shaft 32 and the second position which is visible from the outside of the support shaft 32, and by moving to the second position, It is displayed that the core body 61 is mounted on the outer periphery of the support shaft 32. When the core body 61 is not mounted on the outer circumference of the support shaft 32, the mounting display unit 3521 is located at the first position. When the core body 61 is mounted on the outer circumference of the support shaft 32, the support shaft fitting portion 613 as the operating portion activates the link mechanism 35 as the moving operation portion, so that the mounting display portion 3521 is in the second position. It is displayed that the core body 61 is mounted on the outer periphery of the support shaft 32.

A coil spring 353 is provided in the small diameter portion of the lock pin 351. The tip of the coil spring 353 is in contact with the step 3511 of the lock pin 351 and the base end is in contact with the main body of the support shaft 32 (exterior portion 32o). Therefore, the lock pin 351 is urged toward the base end of the support shaft 32 via the step. Due to this urging, the lock pin 351 normally protrudes from the support shaft 32 (exterior portion 32o) toward the proximal end side as shown in FIG. Further, as shown in FIG. 8, when the lock pin 351 is immersed in the support shaft 32 (exterior portion 32o), the coil spring 353 is compressed.

As shown in FIG. 9, the link body 354 has a body portion 3541 that is substantially annular in the axial direction of the support shaft 32. The link body 354 has a pair of link rotation support shafts 3542 protruding outward from the main body portion 3541 at the center in the vertical direction in the illustrated state. The link rotation support shaft 3542 is supported by the main body of the support shaft 32 (exterior portion 32o) (a tubular portion of the exterior portion 32o excluding the link mechanism 35). Therefore, the link body 354 is supported with respect to the main body of the support shaft 32 (exterior portion 32o) so as to be rotatable (swing) within a predetermined range as shown by an arrow R in FIG. A concave groove 32B extending in the circumferential direction and open in the inner diameter direction is formed on the inner peripheral surface of the exterior portion 32o, and the link body 354 rotates in the space of the concave groove 32B. Therefore, the link body 354 does not interfere with the inner shaft 32i. When the support shaft 32 has an integral structure, a space is formed inside the support shaft 32 to allow the link body 354 to rotate. This space can be a closed space except for the portion through which the pressed portion 3543 penetrates. The upper end of the link body 354 is connected to a moving body (specifically, an extension plate 352). This connection is a rotatable connection, and can cope with an angle change with a moving body (extension plate 352 in the present embodiment) accompanying the rotation of the link body 354. The lower end of the link body 354 penetrates the main body of the exterior portion 32o in the radial direction and projects into the space inside the core body guide groove 329. This protruding portion is a pressed portion 3543 as an engaged portion, which is acted on by the core body 61. In addition, "pressing" of this embodiment is an example of one aspect of "engagement". The pressed portion 3543 is located at a position shifted from the position of the tip portion to the base end portion side on the support shaft 32. As shown in the figure, the link body 354 is rotated by being pushed by the end portion (base end 6131 in the normal mounting direction) of the support shaft fitting portion 613 (indicated by the broken line) in the core body 61. The pressed portion 3543 is provided on the side opposite to the moving body (specifically, the lock pin 351) with the axis of the link rotation support shaft 3542 in the radial direction. Therefore, the moving direction of the pressed portion 3543 and the moving direction of the moving body (lock pin 351 and extension plate 352) are opposite to each other.

Regarding the correspondence between the drug packaging device 1 and the winding body 6 (specifically, the combination of the packaging material supply unit 3 and the core body 61), which is related to the function to be noted in the packaging material supply unit 3 of the present embodiment. It will be described later.

-Core body of winding body-
As shown in FIG. 5, the core body 61 of the winding body 6 is a tubular body having a circular shape in the radial cross section. The packaging material 62 is wound around the outer peripheral surface of the core body 61. The outer diameter of the core body 61 is constant in the axial direction. Therefore, since no step appears on the outer peripheral surface, the packaging material 62 can be wound without making a crease. The core body 61 is attached / detached (attached / detached) by being moved in the axial direction with respect to the outer circumference of the support shaft 32 in the packaging material supply unit 3. The core body 61 is aligned in the circumferential direction of the support shaft 32 and is mounted on the outer periphery of the support shaft 32. The core body 61 has one end and the other end. The core body 61 is mounted on the support shaft 32 from one end side in a normal direction (mounting direction). The core body 61 is provided with a notch 611 at a base end portion in a direction (regular mounting direction) when mounted on the support shaft 32. The cutout portion 611 is provided at a position corresponding to the packaging material breakage detection pin 323 that protrudes in the outward diameter direction from the support shaft 32 when the core body 61 is attached to the support shaft 32 (see FIG. 6). The cutout portion 611 has a space that penetrates the core body 61 in the radial direction and is open to the base end of the core body 61. In this space, the packaging material breakage detection pin 323 can move in the axial direction of the support shaft 32. This movement is performed after the packaging material 62 is pulled out from the winding body 6 and disappears. Incidentally, the cutout portion 611 can also be used as a clue when the operator identifies the direction of the winding body 6.

As shown in FIGS. 5 and 6, the inner peripheral surface of the core body 61 has a large diameter at the proximal end side and the distal end side in the axial direction, and a small diameter at the central side, so that the proximal end side and the distal end side are formed. A step portion 612 is formed on the surface. Of these, the displacement regulating portion (the outer displacement regulating portion 327 in the present embodiment) engages with the step portion 612 on the tip side. Therefore, it is possible to prevent the core body 61 from being displaced in the axial direction with respect to the support shaft 32, and the winding body 6 can be reliably mounted on the support shaft 32. On the other hand, since the outer displacement regulating portion 327 is spring-biased, for example, when the core body 61 is pulled out from the support shaft 32, if the core body 61 is moved in the axial direction with a force that overcomes the urging force of the spring, for example, The core body 61 moves with respect to the support shaft 32. Therefore, when the core body 61 is pulled out from the support shaft 32, the work can be performed without any particular problem.

A support shaft fitting portion 613, which is a series of ridges extending in the axial direction, protrudes from the inner peripheral surface of the core body 61. The support shaft fitting portion 613 is integrally formed with the tubular main body of the core body 61. In other words, the core body 61 includes a core body formed in a tubular shape and a support shaft fitting portion 613 provided on the core body. The support shaft fitting portion 613 is formed asymmetrically in the axial direction. Specifically, the core body 61 is offset to the tip in the axial direction in the normal mounting direction with respect to the support shaft 32 (see FIG. 5). That is, in the direction reference of the support shaft 32, the distance from the tip of the core 61 to the tip 6132 of the support shaft fitting portion 613 is compared with the distance from the base end of the core body 61 to the base end 6131 of the support shaft fitting portion 613. The distance is small. Therefore, the support shaft fitting portion 613 as the insertion portion is located at a position shifted from the position of the one end portion to the other end side in the core body 61.

The core body 61 is formed of, for example, a hard resin. Therefore, the core body 61 can be used repeatedly many times by reusing it after the packaging material 62 is used up. This can contribute to the saving of petroleum resources, for example. The reuse is performed by winding a new packaging material 62 around the used core body 61 collected from the user of the drug packaging device 1. By winding the new packaging material 62 around the core body 61 to be reused, the new winding body 6 is manufactured. In addition, in order to facilitate the collection, of the winding body 6 to be handed over to the user, the core body 61 is lent out so that the user returns the core body 61. Can be encouraged to be collected.

To wind the new packaging material 62 around the used core body 61, for example, the new packaging material 62 is wound on a separate core body (paper cylinder or the like) having an inner diameter dimension larger than the outer diameter dimension of the core body 61. By winding, a prefabricated packaging material roll (replacement winding body) may be attached to the used core body 61. When this method is adopted, a spacer such as a rubber ring is interposed between the used core body 61 and the separate core body to determine the outer diameter dimension of the core body 61 and the inner diameter dimension of the separate core body. You can also adjust the difference.

The new winding body 6 can be manufactured by the supplier of the winding body 6, or the user can perform the work related to the manufacturing by instructing the user by the supplier of the winding body 6. You can also. In the latter case, the used core body 61 is not collected and is kept in the user's hand. The instructions from the supplier of the winder 6 to the user may be explicit or implied. The latter implied instruction also includes simply transferring the replacement winding to the user.

Regarding the core body 61 of the present embodiment, the correspondence relationship between the configurations of the drug packaging device 1 and the winding body 6 (specifically, the combination of the packaging material supply unit 3 and the core body 61), which is related to the function to be noted. Will be described later.

-Configuration to facilitate mounting work-
Next, a configuration related to the combination of the drug packaging device 1 and the winding body 6 for facilitating the mounting work of the winding body 6 on the support shaft 32 will be described.

The packaging material supply unit 3 in the drug packaging device 1 includes a lock unit (or rotation regulation unit) that regulates the rotation of the support shaft 32 with respect to the base 31, and a regulation release unit that releases the regulation (rotation regulation) by the lock unit. Be prepared. The lock portion corresponds to the lock pin 351 and the lock pin engaging portion 33 of the present embodiment. The lock portion (lock pin 351 and lock pin engaging portion 33) regulates the rotation of the support shaft 32 with respect to the base 31 when the core body 61 is not mounted on the outer circumference of the support shaft 32. The link body 354 of this embodiment corresponds to the deregulation section. The regulation release portion includes a pressed portion 3543 that is pressed by the axial movement of the core body 61. In the present embodiment, the pressed portion 3543 is formed at the lower portion of the link body 354 in the direction shown in FIG. The support shaft 32 includes a recess along the axial direction having a pressed portion 3543. The recess corresponds to the core body guide groove 329 of the present embodiment.

Corresponding to the configuration of the packaging material supply unit 3, the core body 61 includes a release actuating portion (or actuating portion). This release operating portion releases the restriction by the lock portion (lock pin 351 and lock pin engaging portion 33) by operating the regulation release portion of the packaging material supply portion 3 when mounted on the support shaft 32. .. The release operating portion includes a pressing portion as an engaging portion that presses the pressed portion 3543 in response to the axial movement of the core body 61 with respect to the support shaft 32. This pressing portion is provided on a protrusion protruding from the inner peripheral surface of the core body 61. The protrusion as the release operating portion corresponds to the support shaft fitting portion 613 of the present embodiment. The pressing portion corresponds to the base end 6131 of the support shaft fitting portion 613 in the present embodiment in the direction reference of the support shaft 32. The release operating portion includes an insertion portion (support shaft fitting portion 613) that protrudes inward from the inner peripheral portion of the core body 61 and is inserted into the core body guide groove 329. The pressing portion is formed in the insertion portion. When the core body 61 is mounted on the outer periphery of the support shaft 32, the release operating portion (support shaft fitting portion 613) operates the regulation release portion (link body 354) to act on the lock portion (lock pin 351 and the lock pin 351 and the lock pin 354). The rotation restriction of the support shaft 32 by the lock pin engaging portion 33) is released.

Here, in the conventional packaging material supply unit 3, since the support shaft rotates freely, when the winding body is to be mounted, the winding body is rotated in the circumferential direction so as to be aligned with the support shaft. Since the support shaft and the winding body may rotate together, for example, the operator must rotate the winding body while holding the support shaft with one hand, and the mounting work of the winding body is complicated. It was.

On the other hand, due to the combination of the packaging material supply unit 3 and the core body 61 configured as described above, the lock pin 351 is the base end surface of the support shaft 32 when the winding body 6 is not mounted on the support shaft 32. The support shaft 32 is locked so as not to rotate by protruding from the lock pin and engaging with the lock pin engaging portion 33. As a result, the rotation of the support shaft 32 is restricted. The support shaft 32 cannot rotate in the circumferential direction until the mounting of the support shaft 32 of the winding body 6 to the regular mounting position is completed. Further, the support shaft fitting portion 613 is located at a position shifted from the position of one end portion to the other end portion side in the core body 61. Therefore, the operator can align the winding body 6 and the support shaft 32 in the circumferential direction with the winding body 6 inserted halfway into the support shaft 32. Then, when the winding body 6 is mounted on the support shaft 32, the base end 6131 of the support shaft fitting portion 613 which is the pressing portion presses the pressed portion 3543 which is a part of the link body 354. That is, the pressing portion presses the pressed portion 3543 in the mounting direction as the core body 61 moves from the tip end portion of the support shaft 32 toward the base end portion in the mounting direction. As a result, the link mechanism 35 operates (specifically, the link body 354 rotates), and the lock pin 351 immerses in the base end surface of the support shaft 32 and separates from the lock pin engaging portion 33, whereby the support shaft 32 Is unlocked.

As described above, in the present embodiment, when the winding body 6 is mounted on the support shaft 32, the release operating portion (support shaft fitting portion 613) operates the regulation release portion (link body 354) to act as the lock portion (lock portion (link body 354)). The regulation by the lock pin 351 and the lock pin engaging portion 33) is released. Therefore, the support shaft 32 can be made non-rotatable in the circumferential direction until the mounting of the winding body 6 on the support shaft 32 is completed. Therefore, it is easy to align the winding body 6 and the support shaft 32 in the circumferential direction. Further, the pressing portion (base end 6131) presses the pressed portion 3543 according to the movement of the core body 61 in the axial direction, whereby the regulation release portion (link body 354) can be operated. Therefore, the operation for releasing the regulation by the lock portion (lock pin 351 and lock pin engaging portion 33) can be simplified. Further, the regulation release portion (link body 354) can be operated by the combination of the concave portion (core body guide groove 329) and the protrusion (support shaft fitting portion 613). Therefore, the configuration for releasing the regulation by the lock portion (lock pin 351 and lock pin engaging portion 33) is simple.

Therefore, according to the present embodiment, the winding body 6 can be easily attached to the support shaft 32.

-Configuration to prevent reverse mounting-
Next, a configuration related to the combination of the drug packaging device 1 and the winding body 6 for preventing the winding body 6 from being mounted on the support shaft 32 in the direction opposite to the normal direction will be described.

The packaging material supply unit 3 in the drug packaging device 1 includes a device-side blocking unit. The device-side blocking portion is located on the support shaft 32. The device-side blocking portion prevents the winding body 6 from being mounted in the regular mounting position in a non-regular orientation opposite to the regular orientation. The device-side blocking portion is provided on the outer peripheral surface of the support shaft 32. The device-side blocking portion is provided in a recess provided along the axial direction of the support shaft 32. This recess is a recess groove formed from the tip to the middle of the base end side. The concave portion and the concave groove correspond to the core body guide groove 329 of the present embodiment. Further, the device-side blocking portion is a base end portion that is a dead end in the axial direction of the support shaft 32 in the core body guide groove 329 of the present embodiment. That is, the core body guide groove 329 is formed with a contacted portion with which the support shaft fitting portion 613 of the core body 61 abuts. In the support shaft fitting portion 613, the portion that comes into contact with the contacted portion is the contact portion. The contacted portion is located on the support shaft 32 at the central portion between the base end portion and the tip end portion, specifically, between the base end portion and the tip end portion. The contact portion is located closer to the other end of the core body 61.

Corresponding to the configuration of the packaging material supply portion 3, the core body 61 includes a core body side blocking portion. When the core body side blocking portion is intended to be mounted on the support shaft 32 with one end side of the core body 61 in the axial direction toward the base 31 as a normal orientation, the support shaft fitting portion 613 of the core body guide groove 329 Since the base end 6131 is moved without being caught, it is allowed to move in the axial direction to the regular mounting position. That is, when the core body 61 is mounted on the support shaft 32 from one end side in the normal orientation, the core body 61 is allowed to move to the regular mounting position with respect to the support shaft 32. During this mounting, the support shaft fitting portion 613 including the contact portion does not abut on the contacted portion. On the other hand, when the other end side of the core body 61 in the axial direction is mounted on the support shaft 32 toward the base 31 as a non-regular orientation, the tip 6132 of the support shaft fitting portion 613 in the core body guide groove 329 (Strictly speaking, it is caught when the tip 6132, which is the contact portion, comes into contact with the base end portion of the core body guide groove 329, which is the contact portion). Therefore, the axial movement to the regular mounting position is blocked on the way. More specifically, the core body side blocking portion abuts in the device side blocking portion in the axial direction when the other end side of the core body 61 in the axial direction is to be mounted on the support shaft 32 toward the base 31. This prevents movement in the non-regular orientation. That is, when the core body 61 is mounted on the support shaft 32 from the other end side in a non-regular direction opposite to the normal direction, the contact portion abuts on the contacted portion in the middle of the mounting. The core body 61 is prevented from moving to the regular mounting position with respect to the support shaft 32 on the way. For this purpose, the core body 61 includes a protrusion that protrudes from the inner peripheral surface and has a core body side blocking portion. The protrusions are ridges that are continuously formed in the axial direction and fit into the core body guide groove 329, which is a concave groove. The protrusions and ridges correspond to the support shaft fitting portion 613 in the present embodiment. Further, the core body side blocking portion corresponds to the tip 6132 of the support shaft fitting portion 613 in the present embodiment. In this protrusion (support shaft fitting portion 613), the first end portion on the base 31 side when the winding body 6 is in the normal direction, that is, when the core body 61 is in the direction shown in FIG. It does not come into contact with the device-side blocking part until it reaches the regular mounting position. On the other hand, the second end portion on the side opposite to the first end portion in the axial direction comes into contact with the device-side blocking portion before reaching the regular mounting position. Further, compared to the distance from the end edge on the base 31 side to the first end portion when the winding body 6 is in the normal orientation, the second end from the end edge on the opposite side in the axial direction in the core body 61. The distance to the part is small. The first end corresponds to the base end 6131 of the support shaft fitting portion 613 in the present embodiment in the direction reference of the support shaft 32. The second end corresponds to the tip 6132 of the support shaft fitting portion 613 in the present embodiment in the direction reference of the support shaft 32. The second end (tip 6132) functions as a reverse mounting prevention portion, is provided at the same position with respect to the first end (base end 6131) in the circumferential direction of the core body 61, and is provided on the opposite side in the axial direction. It is provided at the position.

Here, conventionally, the device side has not taken special measures to prevent the winding body from being mounted on the support shaft in the direction opposite to the normal direction, and the correct orientation of the winding body is used in the instruction manual or the like. It was only to remind the worker to wear the.

On the other hand, when the winding body 6 is mounted in the opposite direction to the support shaft 32 by the combination of the packaging material supply portion 3 and the core body 61 configured as described above, the support shaft which is the second end portion is used. The tip 6132 of the fitting portion 613 comes into contact with the base end portion of the core body guide groove 329, which is the device-side blocking portion. Therefore, the winding body 6 can be inserted only halfway. Therefore, in the case of reverse mounting, the mounting of the support shaft 32 at the regular mounting position cannot be completed. Further, in the present embodiment, reverse mounting can be prevented in a direction consistent with the mounting direction of the core body 61 with respect to the support shaft 32. Further, since the contacted portion is located at the central portion between the base end portion and the tip end portion on the support shaft 32 and the contact portion is located near the other end portion of the core body 61, the core body 61 When mounted on the support shaft 32 in a non-regular orientation, the contact portion abuts on the contacted portion at an early stage in the middle of the process, and the movement of the core body 61 with respect to the support shaft 32 is prevented. Therefore, the operator can more reliably grasp that the core body 61 is to be mounted on the support shaft 32 in a non-regular orientation. Further, a protrusion (support shaft) having a recess (core guide groove 329) provided in the support shaft 32, a first end portion (base end 6131) provided in the core body 61, and a second end portion (tip 6132) on the opposite side. It is combined with the fitting portion 613). Further, the first end portion (base end 6131) and the second end portion (tip end 6132) can be formed depending on the distance from the end edge of the core body 61 of the ridge (support shaft fitting portion 613). Therefore, reverse mounting can be prevented with a simple configuration.

Therefore, according to the present embodiment, it is possible to prevent the winding body 6 from being mounted on the support shaft 32 in the direction opposite to the normal direction.

-Configuration for confirming installation in the normal position-
Next, a configuration related to the combination of the drug packaging device 1 and the winding body 6 will be described so that the operator can easily confirm whether or not the winding body 6 is securely attached.

The packaging material supply unit 3 in the drug packaging device 1 includes a pressed unit 3543 and a mounting notification unit. The pressed portion 3543 is provided on the support shaft 32. The pressed portion 3543 is moved along with the axial movement of the winding body 6 when it is attached to the support shaft 32. The state of the mounting notification unit changes as the pressed unit 3543 moves. As a result, the operator is notified that the winding body 6 has been mounted at the regular mounting position of the support shaft 32. The mounting notification unit is located on the support shaft 32. The mounting notification unit is provided on a long body whose tip moves to a position visible to the operator in conjunction with the movement of the pressed portion 3543 when the winding body 6 is mounted. The elongated body corresponds to the extension plate 352 of the link mechanism 35 in the present embodiment. The mounting notification unit is located on the end surface of the support shaft 32 on the front side (that is, the tip end side of the support shaft 32) with respect to the moving direction when the winding body 6 is attached to the support shaft 32. Further, the mounting notification unit is located at the tip of the long body in the direction reference of the support shaft 32. The mounting notification unit corresponds to the mounting display unit 3521 formed at the end of the extension plate 352 in the present embodiment. Further, the link mechanism 35 as a movement operation unit for moving the mounting display unit 3521 includes a pressed portion 3543.

Corresponding to the configuration of the packaging material supply unit 3, the core body 61 includes a pressing portion that presses the pressed portion 3543 of the packaging material supply unit 3 in response to the axial movement of the core body 61 with respect to the support shaft 32. The pressing portion is a protrusion protruding from the inner peripheral surface of the core body 61. The pressing portion corresponds to the support shaft fitting portion 613 (particularly the portion including the base end 6131) in the present embodiment. The pressing portion presses the pressed portion 3543 in order to move the long body (extension plate 352) of the mounting notification portion in the packaging material supply portion 3 in the longitudinal direction. The pressing portion is located on the front side (that is, the tip end side of the support shaft 32) with respect to the moving direction when the winding body 6 is mounted, rather than the axial center of the core body 61.

Here, in the conventional packaging material supply unit, a line for mounting the winding body is drawn on the support shaft, but there is room for improvement in that it is difficult for the operator to confirm.

On the other hand, by combining the packaging material supply unit 3 and the core body 61 configured as described above, the pressed portion 3543 of the packaging material supply unit 3 becomes the pressing portion (support shaft fitting portion 613) of the core body 61. When pressed, the mounting display unit 3521 moves to a position visible from the outside of the support shaft 32 (specifically, the mounting display unit 32A of the support shaft 32 is colored. 3521 is located so that it can be seen). That is, the mounting display unit 3521 is connected so as to be interlocked with the pressed unit 3543.

Further, when the engaged portion (pressed portion 3543) is engaged with the engaging portion (base end 6131 of the support shaft fitting portion 613) of the core body 61, the mounting notification unit (mounting display) is interlocked with the engaged portion (pressed portion 3543). The portion 3521) moves to a position visible from the outside of the support shaft 32. Further, by making the engaging portion (base end 6131) a protrusion, it is possible to simplify a configuration for notifying the operator that the winding body 6 has been mounted at the regular mounting position of the support shaft 32. Further, a mounting notification unit (mounting display unit 3521) is provided on a long body (extension plate 352) located on the support shaft 32, and an engaging portion (base end 6131) extends the long body (extension plate 352) in the longitudinal direction. Since the mounting notification unit (mounting display unit 3521) is located near the mounting position of the winding body 6, it is easy for the operator to visually recognize it. Further, since the notification to the operator can be mechanically performed, an electric circuit or the like is unnecessary. Further, since the mounting notification unit (mounting display unit 3521) is located on the front end surface of the support shaft 32, it is easy for the operator to visually recognize. Then, the engaging portion (base end 6131) presses the engaged portion (pressed portion 3543) in the moving direction when the winding body 6 is mounted, thereby working on the mounting notification unit (mounting display unit 3521). The configuration for moving to a position visible to the person can be simplified.

Therefore, according to the present embodiment, the operator can easily confirm whether or not the winding body 6 is securely attached.

-Examples of other forms-
Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

For example, the support shaft fitting portion 613 included in the core body 61 may not have a series of forms as in the above embodiment, but may be formed intermittently in the axial direction.

Further, in the above-described embodiment, the engaging portion is a pressing portion, and the engaged portion is a pressed portion. However, the present invention is not limited to this, and the engagement mode is not limited to pressing as long as the core body 61 is engaged in accordance with the axial movement of the core body 61. For example, it may be engaged by hooking with a claw-shaped body or engaged by pulling out.

Further, the support shaft fitting portion 613 of the above embodiment is integrally formed with the tubular main body of the core body 61. However, the present invention is not limited to this, and the support shaft fitting portion 613 can be formed as a single member. In this case, for example, a recess is formed on the inner peripheral surface of the core 61, and the support shaft fitting portion 613 independently formed is fitted in the recess, whereby the core 61 with the support shaft fitting portion 613 is fitted. Can be formed.

Further, the mounting notification unit is provided on the support shaft 32 in the above embodiment. However, it may be provided in the drug packaging device 1 other than the support shaft 32. Further, in the above-described embodiment, the state change of the wearing notification unit is a mechanically visual change in the notification mode (display), but it may be an electrical state change. For example, the wearing notification unit is a lamp and the lamp is lit to give notification, or the wearing notification unit is a sounding mechanism and the notification chime sound is used to give notification (auditory notification mode).
