Abstract

PROBLEM TO BE SOLVED: To provide an inexpensive winding roll support shaft 20 being a synthetic resin molded article.SOLUTION: The winding roll support shaft is used in a medicine packaging apparatus. On the external surface of the support shaft body 21, a standing/lying piece 22 in the axial direction is provided to be fixed on the support shaft base side. protrusions 23 and 23' on the external surface of the standing/lying piece 22 are locked to the side surface of a protruding strip 13 on the internal surface of a winding roll to prevent the winding roll 10 from idly turning to the support shaft 20. At the same time, another protrusion 24 on the external surface of the standing/lying piece 22 is fastened to the front end surface of the protruding strip 13 to prevent the winding roll 10 from being slipped off from the support shaft 20. During the rotation when unwinding the winding roll 10, the prevention of the slipping off is kept by the resilient force to the outside of the standing/lying piece 22. By the pulling-out force in the axial direction to the winding roll 10, the standing/lying piece 22 warps inward, and the fastening between the other protrusion 24 and the end surface of the protruding strip 13 is released, and the winding roll 10 can smoothly be replaced. In this case, the slopes 23a, 23a' and 24a of the protrusions work as guides.

The present invention relates to a support shaft of a winding roll for printing.

This type of medicine packaging apparatus will be described, for example, with reference to FIGS. 1, 2 and 5 showing an embodiment of the present invention. By operating the control panel Q, a tablet supply unit U ₁ , a powder supply unit U 1 capsule amount of drug on the basis of ₂ the prescription is sent are dropped in sequence into the hopper H of the packaging unit a. In the packaging part A, the packaging bag tape (sheet) t is paid out from the roll T, and necessary information such as the patient name and the medication date and time is printed on the drawn packaging bag tape t in the printing part P. The packaging bag tape t is expanded and opened from the folded state, and the medicine for one package is fed into the opening from the hopper H, and then for the packaging bag so as to confine the medicine in the heat seal portion B. The tape t is sealed (heat-sealed) and packaged and dispensed once (see Patent Document 1, paragraphs 0002 to 0004, 0024, and 0041 to 0068, FIG. 1, FIG. 12, etc.).

In the packaging printing mechanism (packaging part A, printing part P), the packaging tape t and the printing tape 12 are supplied (paid out) from the winding rolls T and 10, and the winding rolls T and 10 are Usually, it is attached to a horizontal support shaft supported like a cantilever so as to be detachable by being inserted and fitted from the tip side.
For example, as shown in FIG. 5, the printing tape winding roll 10 winds a printing tape (carbon tape, ribbon tape) 12 around the outer surface of a cylindrical core (reel) 11, and a core (through hole) 11. A plurality of long ridges 13 extending in the axial direction are formed at equal intervals on the entire inner peripheral surface of the shaft, while the support shaft includes a rotation prevention protrusion and a retaining protrusion that are engaged with the protrusion 13. Is provided on the outer surface.

As shown in FIGS. 10a to 10d, the conventional support shaft 30 is provided on the outer surface of a metal cylindrical support shaft main body 31 with a long undulating piece 32 fastened with a screw 32a on the base side, In the middle of the support shaft main body 31, a metal protrusion 33 that can be moved in and out with a metal spring 33 a is provided.
As shown in FIG. 11, when the winding roll 10 is inserted from the tip of the support shaft 30 (in the direction of the arrow in FIG. 11), the projecting and retracting projection 33 is formed between the protrusions 13 and 13 of the winding roll 10. To prevent the winding roll 10 from rotating around the support shaft 30 (see FIG. 2B), and the tip protrusion 34 of the undulating piece 32 is locked to the tip end surface of the ridge 13. Thus, the winding roll 10 is prevented from coming off from the support shaft 30 (so as not to move in the direction of the arrow in the figure).

JP 2008-273624 A JP 2007-216485 A

In the conventional support shaft 30, the rotation of the winding roll 10 is stopped by the protrusion 33, and the structure of the protrusion 33 and the spring 33 a is the formation of the spring accommodating hole and the protrusion 33 and the spring 33 a to the hole. The loading operation is complicated, which increases the cost. Due to today's demand for cost reduction, this type of support shaft 30 is also desired to be cost-reduced.
Further, the rotation-preventing projection 33 has a cylindrical shape and its tip is hemispherical. When the winding roll 10 is inserted into the support shaft 30, the axis of the projection 33 and the axis of the protrusion 13 are perpendicular to each other. The tip inclined surface 13a of the protrusion 13 and the tip spherical surface of the protrusion 33 abut against each other, and there is a case in which the protrusion 13 does not get over the protrusion 33 and no further winding roll 10 can be inserted.
Furthermore, in recent years, the type of the winding roll 10 has been recorded by an IC tag, and in this case, the IC tag exchanges information by wireless communication using an electromagnetic field or a radio wave. The metal is an obstacle to the exchange, and a change to a material that does not affect the wireless communication such as a synthetic resin is required.

  This invention makes it the 1st subject to aim at the cost reduction of a support shaft in the above condition, and makes it a 2nd subject to make it have no trouble even if an IC tag is provided.

In order to achieve the first object, the present invention first focuses on the fact that the winding roll can be inserted and removed if the projection on the support shaft side is bent, and the projection for preventing the winding roll from coming off is provided. It is made of an elastic body and can be freely raised and lowered.
In this way, if the protrusions can be raised and lowered, when the winding roll is inserted into or pulled out from the support shaft, the protrusions are bent in accordance with the insertion force or the extraction force, and the insertion or extraction is allowed.

Next, according to the present invention, if the side surface of the protrusion that contacts the protrusion is an inclined surface that gradually moves away from the insertion direction of the winding roll, the protrusion of the winding roll is inserted along with the insertion of the winding roll. Paying attention to sliding (moving) along the inclined surface of the projection, the end of the projection that contacts the rotation of the winding roll when the winding roll is inserted has a triangular shape in a plan view with a sharp point in the opposite direction of the insertion It was.
As described above, when the protrusion end portion has a triangular shape in a plan view pointed in the opposite direction, the protrusion of the winding roll slides on the triangular protrusion side surface (inclined surface) as the winding roll is inserted. Since the projection is guided so as to contact the side surface of the ridge, the support shaft and the winding roll rotate relatively by sliding between the inclined surface and the ridge, and the projection contacts the side surface of the ridge. It comes into contact and exhibits the function of preventing the winding roll from spinning.

  As one structure of this invention, it is a support shaft of the winding roll of the packaging bag tape or the printing tape in the medicine packaging apparatus, and the winding roll has a through-hole into which the support shaft enters, A long protrusion in the axial direction is formed on the inner surface of the through hole, supported in a cantilever shape, and a winding roll is fitted from the tip of the through hole through the through hole so that the winding roll cannot be idled. In the support shaft that supports to prevent it from coming off, the undulating piece that is long in the axial direction is fixed to the outer surface of the rod-shaped body on the cantilevered base side, and the tip can be undulated with its own elastic force outward in the radial direction of the body One protrusion is provided on the cantilevered base side of the undulating piece in the main body radial direction of the undulating piece, and the other protrusion is provided on the cantilevered tip side, and the cantilevered tip side of the one protrusion is provided. The part has a triangular shape in plan view that is pointed toward the tip. One projection is locked to the side surface of the ridge to support the winding roll so that it cannot rotate freely, and the other projection is locked to the end face of the cantilevered tip of the ridge to prevent the winding roll from coming off. Further, when the other roll is pushed by the pulling-out force or insertion force of the winding roll at the time of exchanging the winding roll, the undulation piece is bent to allow the movement of the ridge.

  As in the conventional case, when the winding roll is inserted from the tip of the support shaft of this configuration, one protrusion on the outer surface of the undulation piece is locked to the side surface of the protrusion, and the support shaft and the winding roll cannot be idled. The other protrusion on the outer surface of the undulation piece is locked to the tip end face of the ridge to prevent the winding roll from coming off from the support shaft. For this reason, during rotation of the winding roll during tape unwinding, the locking of the protrusions and the protrusions is maintained by the undulation force (elastic force) of the undulation piece, and the winding roll rotates freely and comes off the support shaft. Stop is done. On the other hand, when the winding roll is pulled out in the axial direction of the support shaft, the undulating piece bends inward (falls down) and the other protrusion and the protrusion are released from being locked, and the winding roll can be pulled out from the support shaft. .

  According to another aspect of the present invention, there is provided a support shaft for a winding roll of a packaging bag tape or a printing tape in a medicine packaging device, the winding roll having a through hole into which the support shaft enters. The inner surface of the through-hole is formed with a long ridge in the axial direction, is supported in a cantilever shape, and a winding roll is fitted through the through-hole from the tip of the through-hole. In the support shaft which is supported in a non-detachable manner, one protrusion is provided on the cantilever base side of the outer surface of the rod-shaped body, and the other protrusion is provided on the tip end side of the cantilever. The beam-like tip side portion has a triangular shape in a plan view that is pointed in the tip direction, and the other projection is made of an elastic body and can be undulated by its own bending. When it is locked to the side to support the winding roll The other projection is locked to the end face of the cantilevered tip of the ridge to prevent the winding roll from coming off, and the other projection is removed by the pulling force of the winding roll when the winding roll is replaced. Therefore, it is possible to adopt a configuration in which the protrusion is bent and the movement of the protrusion is allowed and the engagement between the other protrusion and the tip end face of the protrusion is released.

  As in the conventional case, when the winding roll is inserted from the front end of the support shaft of this configuration, one projection is locked to the side surface of the ridge to support the support shaft and the winding roll so as not to idle. The other projection is locked to the end surface of the ridge to prevent the winding roll from coming off from the support shaft. At this time, while the winding roll is rotating at the time of feeding the tape, the rotational force is not so much applied to the other protrusion, so that the protrusion is not bent. It will not bend to the extent that it comes out. For this reason, the winding protrusion is secured by the other protrusion. On the other hand, when the winding roll is pulled out in the axial direction of the support shaft and the other projection is bent by the pulling force, the locking of the projection and the protrusion is released, and the winding roll can be pulled out from the support shaft.

In both of these configurations, if the contact surface at the time of insertion of the retaining protrusion (the other projection) or the contact surface at the time of withdrawal is inclined upward in the opposite direction, it can be used for insertion or withdrawal of the winding roll. Along with this, the inner surface (projection) of the winding roll gradually climbs on the inclined surface and bends (raises) the projection, so that the insertion or withdrawal becomes smooth.
In addition, if the cantilevered tip side of the protrusion for preventing idling (one protrusion) is an upward inclined surface toward the cantilevered base side, the ridge smoothly runs on the inclined surface. The winding roll can be inserted smoothly.
In addition, since the above-mentioned “triangular shape in plan view” is “the isosceles triangle shape in plan view”, the inclination angles of the right and left inclined surfaces in the plan view are the same. The sliding degree is the same on both the left and right sides, and the unevenness is eliminated in the guide in which the protrusion comes into contact with the side surface of the protrusion.

Incidentally, conventionally, the undulating piece 32 shown in FIG. 10a is a molded product of synthetic resin, and the spring 33a and the projection 33 are made of metal. By substituting with one protrusion integral with the piece, the metal part is eliminated and the second problem can be achieved.
In addition, a protrusion (for preventing idling) that supports the winding roll so as not to idle can be provided on the tip end side of the cantilever.
As described above, if the protrusions that support the winding roll so as not to be idle are provided on both sides in the cantilever-like length direction, the support of the winding roll is stabilized. In particular, if both protrusions are located as close to both ends of the support shaft as possible, the support is more stable. When both the protrusions are provided on the undulating piece, one protrusion is located on the base portion side where the undulating piece is not raised and the other protrusion is located on the leading end side where the undulation is raised (see the embodiment of FIG. 4a).

In these configurations, if each of the protrusions is provided at a symmetrical position with respect to the axis of the outer surface of the support shaft main body, the winding roll can be more reliably prevented from slipping off and coming off, and at the symmetrical position. The winding roll is positioned (by the spring effect) by the elastic force of the protrusion or the undulating piece and the centering is automatically performed and fixed (locked).
In addition, if the protrusions and undulations are made of synthetic resin molded products, wood, etc., and made of a material that does not affect wireless communication using electromagnetic fields or radio waves, it is assumed that there is no hindrance to information transmission by the IC tag. Two problems can be achieved. At this time, as long as members other than the support shaft and the undulating piece do not interfere with the information transmission, for example, the screw 36 may be made of metal. Synthetic resin molded products can be easily mass-produced to reduce costs and can be easily recycled.

  In the present invention, as described above, since the protrusion for preventing the winding roll from being formed is formed of an elastic body or formed on an undulating piece, the mechanism can be simple and inexpensive. Further, since the idling prevention projection end portion has a triangular shape in plan view, the projection can smoothly come into contact with the ridge side surface of the winding roll, and the idling prevention function can be effectively exhibited. At the same time, the winding roll can be inserted smoothly. Furthermore, it is easy to make a synthetic resin and the like, which can be advantageous in the use of an IC tag.

Cut front view The winding roll of the embodiment is shown, (a) is a perspective view, (b) is a right side view, and (c) is a cut front view. The state which fitted the winding roll to the support shaft of the embodiment is shown, (a) is a cut front view, (b) is a right side view. Other embodiment is shown, (a) is a perspective view, (b) is a cut front view.

Cut front view The state which fitted the winding roll to the support shaft is shown, (a) is a cut front view, (b) is a right side view.

  This embodiment is used in the medicine packaging apparatus shown in FIG. 1, and, as in the prior art, as shown in FIGS. 2 and 3, a printing tape (ink ribbon) 12 is wound in an ink cartridge (ribbon cassette) C. The winding roll 10 (core 11) is mounted, and the ink cartridge C is fitted to the upper and lower two support shafts (printer shafts) 20 and 20, whereby the winding roll 10 is set. The ink cartridge C is loaded with the roll 10 (core 11) on the unwinding side and the winding side, and the printing tape 12 is pulled out from the feeding side to the front surface of the ink cartridge C to the roll 10 (core 11) on the winding side. By winding, a new tape 12 is always fed out and printed on the front surface thereof. The printing mechanism and its action, the mechanism for exchanging the winding roll 10 to the ink cartridge C, and its action are the same as in the prior art (see Patent Document 1, paragraph 0057, Patent Document 2, paragraph 0033, FIG. 1, FIG. 2, etc.).

  The present invention is characterized by a support shaft to which the ink cartridge C is mounted, and the support shaft 20 of one embodiment shown in FIGS. 4a to 4d is a support shaft body that is a synthetic resin molded product such as polyacetal, for example. On the outer surface 21, an undulating piece 22 that is also long in the axial direction of a synthetic resin molded product such as polyacetal is fixed with a synthetic resin screw 22a on the support shaft base side. The fixed undulation piece 22 has its tip freely undulated by its own internal and external (support shaft radial direction) elastic force.

Protrusions 23, 23 ′ are formed on the same line at both ends of the outer surface of the undulation piece 22, and the tip of the undulation piece 22 bulges into a projection (projection) 24, and the projection 24 is triangular in cross section when viewed from the front. It is made into a shape. The end portions of the projections 23 and 23 'facing each other have an isosceles triangular shape in a plan view that is pointed (at an acute apex angle) in the tip direction, and are upward inclined surfaces 23a and 23a' that face in the opposite direction to the tip. Yes. Further, when the protrusion 24 is mounted in a cantilever shape of the support shaft 20 (see FIG. 3), the tip end of the protrusion 13 is inclined downward when the cantilever-like tip end portion is inserted into the winding roll 10. It is an upward inclined surface (right-side inclined surface of the protrusion 24 in FIG. 4c) 24b toward the cantilevered base side along the surface 13a.
Two undulation pieces 22 are provided at symmetrical positions with respect to the axis. This number is arbitrary, for example, it may be one or three or more. At this time, it is preferable that the undulating pieces 22 are provided at equal intervals around the main body 21.

  As shown in FIG. 4d, the support shaft 20 is formed with an axial hole 25 at the base portion of the main body 21, as shown in FIG. 4D. As shown in FIG. It is inserted into the support shaft S of the frame F of the packaging device through the hole 25 and fixed with a synthetic resin screw 26.

  When the winding roll 10 is inserted into the support shaft 20 as shown by an arrow in FIG. 6A (when the ink cartridge C is fitted), the undulating piece 22 is moved inward as shown by a chain line in FIG. The insertion of the winding roll 10 is allowed by bending. At the time of this insertion, even if the tip of the protrusion 24 hits the protrusion 13, the inclined surface 24 b smoothly deflects the undulation piece 22, and at the same time, the protrusion 23 ′ also bends inward. It can be done smoothly. For this reason, the inclined surface 24b of the protrusion 24 bears the inclined surface of the protrusion 23 'corresponding to the upward inclined surface 23a of the protrusion 23.

  Furthermore, when the protrusion 13 hits the protrusion 23, the protrusion 13 advances while its end inclined surface 13a rides on the upward inclined upper surface of the isosceles triangular inclined surface 23a of the protrusion 23. Since the isosceles triangle-shaped inclined surface 23a is smoothly guided between the protrusions 13 and 13, the support shaft 20 and the winding roll 10 are relatively rotated so that the protrusions 23 and 23 'are the protrusions 13. , 13, and the undulating piece 22 returns with its own elasticity as shown by a chain line in FIG. 6. That is, since the positioning of the winding roll 10 with respect to the support shaft 20 in the circumferential direction is automatically performed and the positioning action is performed by the two undulating pieces 22 symmetric with respect to the axis, alignment is also performed.

  At this time, since the circumferential direction positioning (rotation prevention) of the winding roll 10 is performed by the two protrusions 23 and 23 ', the operation is stably performed over a long period of time and is reliable. In particular, the projection 23 is a rigid body made of a synthetic resin and is located at a base portion where the undulating piece 22 does not undulate (fixed), so that the operation is reliable. Further, since the protrusions 23 and 23 ′ are elongated in the axial direction of the support shaft, the winding roll 10 is stably supported as compared with the conventional cylindrical protrusion 33.

  As described above, when the ink cartridge C is set at a required position (when the winding roll 10 is securely inserted into the support shaft 20), the projections 23 and 23 'in the axial direction are projected into the ridges 13 and 13 respectively. And the protrusion 24 at the front end engages with the front end surface 13a of the protrusion 13, whereby the winding roll 10 is automatically centered with respect to the support shaft 20, and the ink cartridge C (winding) The rotating roll 10) is prevented from coming off, and the winding roll 10 is prevented from idling (integrated).

For this reason, in the set state of the ink cartridge C in FIG. 2, the medicine is packaged in accordance with the operation of the medicine packaging apparatus similar to the conventional one, and the new tape 12 is smoothly fed out from the ink cartridge C so that the tape 12 In addition, the date and time of taking are printed by thermal transfer.
On the other hand, when the tape 12 of the feeding-side winding roll 10 in the ink cartridge C is near the end, that fact is displayed by a lamp or the like, and the operator temporarily stops the operation (dispensing) of the medicine packaging device, Replace the ink cartridge C. At that time, due to the pulling force of the ink cartridge C (winding roll 10) to the outside (front end side) in the axial direction of the support shaft 20, the undulating piece 22 moves to the axial center side as shown by a chain line from the solid line in FIG. It bends to release the locking between the protrusion 24 and the tip end surface 13a of the protrusion 13 and allows the winding roll 10 (ink cartridge C) to move outward in the axial direction (see FIG. 6A). At this time, the engaging surface of the protrusion 24 of the undulating piece 22 (the left slope of the protrusion 24 in FIG. 4C (a)) 24a and the tip engaging (inclined) surface 13a of the ridge 13 are directed outward in the axial direction (FIG. 6). The movement is smooth with an inclination) (lower right of the ridge 13 below (a)).

Other embodiments are shown in FIGS. 7A, 7B, and 8. In the embodiments of FIGS. 7A and 7B, the base-side protrusion 23 is formed integrally with the main body 21, and the distal end side is formed. The projections 23 'and the projections 24 are formed of an elastic material such as rubber such as silicon. The protrusions 23 'and 24 are fixed to the support shaft main body 21 by adhesion, welding, or the like.
The support shaft 20 of this embodiment is also inserted into the support shaft S of the frame F of the medicine packaging device through the hole 25 and fixed with a synthetic resin screw 26 (see FIG. 6).

  When the winding roll 10 is inserted into the support shaft 20 from the tip, the projections 23 'and 24 are bent in the insertion direction as shown by the alternate long and short dash line in FIG. Allow insertion of. Similarly, with the isosceles triangular inclined surface 23a of the protrusion 23, the protrusion 23 is smoothly guided between the ridges 13 and 13, and the support shaft 20 and the winding roll 10 are relatively rotated. The protrusions 23 and 23 ′ are guided between the protrusions 13 and 13, and eventually the protrusions 23 ′ and 24 return with their own elasticity as shown by the solid line from the alternate long and short dash line in FIG. 23'24 prevents the winding roll 10 from rotating and coming off.

On the other hand, when the winding roll 10 is pulled out, the pulling force similarly causes the protrusion 24 to bend from the solid line in FIG.
In this embodiment, as shown in FIG. 8, the protrusion 23 ′ and the protrusion 24 may be separated. At this time, the end of the protrusion 23 ′ on the protrusion 24 side (right side in FIG. 8) is also an isosceles triangular inclined surface in the same manner as the end on the opposite side (same left side), and the ridge 13 is inserted when the winding roll 10 is inserted. It is preferable to smoothly get over the protrusion 23 '. The aspect in which the protrusion 23 ′ is separated from the protrusion 24 can also be adopted in the embodiment of FIG. 4a. Incidentally, when the protrusion 23 'and the protrusion 24 are connected (integral) as shown in FIGS. 4a and 7a, the protrusion 23' also falls (bends) as the protrusion 24 falls (bends). Therefore, there is an advantage that the protrusion 13 can easily get over the protrusion 23 '.

As shown by a chain line in FIG. 5, an IC tag 40 on which information such as the specification of the winding roll 10 and the type of the tape 12 is recorded is attached in the middle of the core 11, and as shown by the chain line in FIG. 21 is provided with the information passing sensor 41. Since the support shaft main body 21, the undulating piece 22, and the screw 22a are made of synthetic resin or the like, the IC tag 40 and the sensor 41 are not subjected to wireless communication by electromagnetic fields or radio waves. There was no problem. At this time, even if the screw 26 was made of metal, there was no hindrance to the wireless communication. From this, the support shaft body 21 and the undulating piece 22 are made of a material that does not interfere with wireless communication, such as at least synthetic resin, and the members at positions that do not interfere with wireless communication depending on the positions of the IC tag 40 and the sensor 41, As can be seen, for example, the screws 26 and the like need not be made of synthetic resin.
Therefore, the positions of the IC tag 40 and the sensor 41 are arbitrary, and a component such as a synthetic resin is appropriately selected depending on the positions. In the case of the ink cartridge C, the IC tag 40 is attached to the casing of the ink cartridge C. On the other hand, the sensor 41 can also be attached to the frame F side or the like.
Incidentally, in the conventional support shaft 30 of FIG. 10, even if the main body 31 and the undulating piece 32 are made of synthetic resin, the protrusion 33 and the spring 33a are made of metal, so that a failure occurs in communication by the IC tag 40. .

In the above embodiment, the winding roll 10 is loaded into the ink cartridge C. However, as shown in FIG. 9, the present invention is also adopted in a mode in which the winding roll 10 is directly attached to and detached from the support shaft 20. Needless to say, it can also be used for the winding roll T of the packaging tape t, and it can be used for the support shafts of various tape winding rolls of other drug packaging apparatuses. Further, one of the anti-rotation protrusions 23 and 23 'can be omitted as long as there is no hindrance. For example, only the protrusion 23 on the base side may be used.
As described above, the scope of the present invention is not limited to the above-described embodiment, is shown by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of the claims. The
Incidentally, the support shaft 20 of the present invention is not limited to the medicine packaging device, but is used to support a winding roll that automatically feeds strings and various tapes in other various devices (machines), for example, in a packaging device. Can do.
