Description

  TECHNICAL FIELD The present invention relates to a medicine packaging device that puts medicine into a long packaging sheet to be conveyed and seals it to form a package.

  2. Description of the Related Art A medicine packaging device that forms a medicine package is widely used (see, for example, Patent Document 1). This medicine packaging device includes a sheet transporting device for transporting a long packaging sheet having an open end in the longitudinal direction, a medicine feeding unit for feeding the medicine into the packaging sheet, and the packaging sheet individually sealed. And a sealing device for forming a packaged body.

  In this medicine packaging apparatus, after a series of medicine packaging is completed, an empty package, which is a packaging body in which no medicine is placed, is formed. The user of the medicine packaging device can cut the packaging sheet at the empty packaging portion. For this cutting, the medicine packaging device is provided with a cutting blade portion facing the conveyance path of the packaging sheet.

  The individual empty packages formed by this medicine packaging apparatus had the same longitudinal dimensions as the individual packaging bodies containing the medicines that were subjected to the above-mentioned series of packaging. When doing so, the longitudinal dimension of the package for the next series of packages can be changed). Here, in the section from the seal formation position to the position of the cutting blade portion in the sealing device, the medicine cannot be put in after the series of packaging is finished and the next series of packaging is performed. The package in this section is always an empty package.

  For example, it is assumed that the distance from the seal forming position to the cutting blade portion is 120 mm. Here, when the longitudinal dimension of each package is 60 mm, for example, as shown in FIG. 6A, the empty package HE is formed into 180 mm for three packages (not 120 mm for two packages). This is because if the thickness is 120 mm, the packaging sheet is cut out immediately after the final package HL containing the medicine, and the final package HL may be damaged (medicine spills down). The length of one package adjacent to is a marginal dimension). When the same dimension is 80 mm, as shown in FIG. 6B, the empty package HE is formed as 160 mm for two packages. When the same dimension is 90 mm, as shown in FIG. 6C, the empty package HE is formed as 180 mm for two packages.

  According to the above, on the basis of the distance (120 mm) from the seal formation position to the cutting blade part, when the longitudinal dimension of each package is 60 mm, 60 mm is extra (180 mm-120 mm). When the dimension is 80 mm, 40 mm is extra (160 mm-120 mm). When the dimension is 90 mm, 60 mm is extra (180 mm-120 mm). Since the medicine is not put into the empty package, the extra-sized packaging sheet can only be discarded after being cut out, which is useless.

  The guide unit 1 includes a triangular plate 14. The triangular plate 14 is located in a space in the packaging sheet P that is folded in half. The triangular plate 14 is wider than the width of the region where the packaging sheet P is conveyed at the position of a medicine loading hopper 21 described later, and has a substantially triangular shape in plan view. The triangular plate 14 is located downstream of the guide roller 11 in the transport direction X and upstream of the hopper 21. The triangular plate 14 can open the open end Pa formed in the longitudinal direction of the packaging sheet P guided by the guide roller 11, and the displacement of the open end Pa of the packaging sheet P (so-called sealing) Ear misalignment) can be corrected.

  The drug charging unit 2 includes a drug charging hopper 21. The medicine charging hopper 21 receives a predetermined amount of medicine supplied from the medicine distribution and supply device, and puts the medicine into a space in the packaging sheet P in a folded state. This medicine loading hopper 21 has a medicine supply port 21b through which the medicine from the medicine distribution and supply device is supplied at the upper end, and a medicine input port 21a for feeding the supplied medicine into the packaging sheet P at the lower end. Have. In the hopper 21, the medicine inlet 21 a is positioned in the space in the packaging sheet P through the open end Pa of the packaging sheet P opened by the triangular plate 14. Thereby, the predetermined amount of medicine supplied to the medicine packaging device A is put into the packaging sheet P without being scattered.

  The heat sealing apparatus 3 performs heat sealing on the packaging sheet P conveyed by the sheet conveying apparatus 4. As a result, individually partitioned packages H as shown in FIG. 3 are formed. As shown in FIGS. 1 and 2, the heat seal device 3 includes a pair of substantially L-shaped seal portions 30 including a short-direction seal portion 31 and a long-direction seal portion 32, and the pair of seal portions. 30 and a seal drive unit 33 connected to the control unit CONT. The heat sealing device 3 includes a perforation forming part 34.

  The short-side seal portion 31 extends slightly outside the end portion in the short-side direction of the packaging sheet P that is folded in two, and is positioned along the short-side direction. By this short direction seal portion 31, a short direction seal S1 extending in the short direction is formed on the packaging sheet P. Further, the longitudinal seal portion 32 is formed to be slightly longer than the length of one package set so that the package H formed on the packaging sheet P can be packaged, and at the open end Pa of the packaging sheet P. Located along. The longitudinal seal portion 32 forms a longitudinal seal S2 extending in the longitudinal direction on the packaging sheet P.

At least one of the pair of seal portions 30 includes a heater, and the packaging sheet P in which the pair of seal portions 30 is folded in two while the heater provided with the heater is heated. By sandwiching, the packaging sheet P can be heat sealed.

  The perforation forming part 34 forms the perforation M (see FIG. 3) in the short direction of the packaging sheet P. As shown in FIG. 2, the perforation forming portion 34 includes a blade portion 341 provided on the inner surface of the short-side seal portion 31 on one side of the pair of seal portions 30 and a pair of seal portions 30. The receiving part 342 provided in the inner surface of the transversal direction seal part 31 in the other side is provided. Although not shown, the blade part 341 is fixed to the base of the short-side seal part 31. On the other hand, the short-side seal portion 31 is spring-supported with respect to the base. With this configuration, when the pair of seal portions 30 sandwich the packaging sheet P, the short-side seal portion 31 moves in the approaching direction with respect to the base, whereby the blade portion 341 fixed to the base. Protrudes from the inner surface of the short-side seal portion 31. Thereby, when the pair of seal portions 30 sandwich the packaging sheet P, the perforations M can be formed on the packaging sheet P by pressing the respective transverse direction seal portions 31. The perforation M formed by the perforation forming unit 34 of the present embodiment is merely an example, and is not limited to this. That is, the structure which can assist the cutting | disconnection in the transversal direction of the packaging sheet P by a user or a patient should just be formed in the packaging sheet P, and structures other than the perforation M may be sufficient.

  In the heat seal device 3, the pair of seal portions 30 are disposed to face each other with the packaging sheet P interposed therebetween. As a result, the seal drive unit 33 that has received an instruction from the control unit CONT (see FIG. 2) causes the pair of seal portions 30 to sandwich the packaging sheet P from both sides in the opposite direction, and heat-seal (heat-press). The packaging sheet P is packaged one by one, and a plurality of individually packaged packages H are formed in series. At the same time, the perforation forming part 34 forms the perforation M in the heat-sealed portion. In addition, the distance in the longitudinal direction (X direction in the drawing) in which the short direction seal portion 31 forms the short direction seal S1 is variable by a sheet conveying device 4 described later. As the interval in the longitudinal direction in this embodiment, 60, 70, 80, and 90 mm can be selected, and the seal interval is variable.

  As described above, the heat sealing apparatus 3 performs heat sealing in a state in which the medicine is put into the transported packaging sheet P. However, as shown in FIG. A plurality of empty packages HE that are not packaged with a medicine among the package H are formed upstream of the final package HL in the transport direction X. That is, the formed plurality of package bodies H include a plurality of medicine-containing package bodies and a plurality of empty packages HE in which medicine is not packaged. The heat sealing apparatus 3 of the present embodiment heats at least one of the plurality of empty packages HE so that the longitudinal dimension is smaller than the final package HL (the longitudinal dimension is 60 mm in the present embodiment). Seal to form. In the present embodiment, as shown in FIGS. 3 and 4, when the package H (packaging sheet P) is cut immediately adjacent to the final package HL (upstream in the transport direction X of the final package HL). At least one narrow empty package HEa (20 mm in this embodiment), which is an empty package having a small size in the longitudinal direction, which is a marginal dimension, is formed. The perforation forming part 34 also forms the perforations M so as to coincide with the seal portion of the narrow empty package HEa.

  The sheet conveying device 4 conveys the packaging sheet P in the longitudinal direction (X direction in the drawing). The sheet conveying device 4 includes a pair of feed rollers 41 and a roller drive unit 43 (see FIG. 2) that is a drive unit that rotationally drives the pair of feed rollers 41 and is connected to the control unit CONT. In response to an instruction from the control unit CONT, the sheet conveying device 4 rotates the pair of feed rollers 41 in the arrow direction shown in FIG. The packaging sheet P can be conveyed by the rotation of the feed roller 41.

  Furthermore, the medicine packaging apparatus A includes a dust collecting device 5, a printing device 6, and a cutting blade portion 7. For example, as shown in FIG. 1, the dust collector 5 includes a shutter plate 51 having a dust collection port 51 a partially cut out and an air suction device (not shown). The medicine supply port 21b of the hopper 21 is shielded by the shutter plate 51 except the dust collection port 51a, and air is sucked from the dust collection port 51a by an air suction device. Along with this, air is sucked from the medicine inlet 21 a of the hopper 21 to clean the residual medicine in the hopper 21. Thereby, the hopper 21 is collected.

  As shown in FIG. 2, the printing device 6 includes a print head 61 connected to the control unit CONT. The print head 61 that receives an instruction from the control unit CONT displays information related to drug administration such as a medication date and a patient name. Prior to the introduction of the medicine, printing is performed at a position corresponding to the package H into which the medicine of the packaging sheet P is to be placed. The printing device 6 is located upstream of the heat sealing device 3 in the sheet conveyance direction X. It should be noted that information related to drug administration such as medication date and time and patient name is input by an input means (not shown) provided in the medicine packaging device, and is also stored in a storage means (not shown) provided in the medicine packaging device. It is recorded.

  As shown in FIG. 2, the control unit CONT is connected to the seal drive unit 33, the roller drive unit 43, and the print head 61, and can control the operation of the medicine packaging apparatus A, and is connected to a storage means (not shown). ing. This storage means is composed of a ROM or the like and stores a control program. The control program is executed in the control unit CONT. This control program causes the control unit CONT to function as control means for a medicine packaging operation and the like as will be described later.

  As shown in FIG. 2, the cutting blade portion 7 is located on the downstream side in the transport direction X from the heat seal device 3, and a user (operator or the like) is a packaging sheet P, more specifically, a plurality of individual sections. Is used to cut out the package H in a series of states. The sheet conveying apparatus 4 according to the present embodiment conveys the packaging sheet P so that the perforation M is coincident with the cutting blade portion 7 and stopped under the control of the control unit CONT.

  The cutting blade portion 7 has a saw-like blade. The cutting blade portion 7 may have, for example, a blade having a curved portion 71 as shown in FIG. 5 (A), or a straight blade as shown in FIG. 5 (B). May be. In addition, the bending portion 71 may be a straight line in which the blade is inclined in an oblique direction as illustrated, or may be a curved line.

  In the cutting blade portion 7 provided with the curved portion 71 shown in FIG. 5A, the starting point when the user cuts the package H is downstream in the transport direction X from the portion other than the curved portion 71 in the cutting blade portion 7. Located on the side. Due to this positional relationship, the user needs to twist the packaging sheet P as shown in FIG. 5 (B) at the start of cutting with a straight blade, whereas as shown in FIG. 5 (A). Thus, the cutting of the package H can be started almost without twisting the packaging sheet P. Therefore, the usability of the medicine packaging apparatus A can be improved.

  The sheet conveying apparatus 4 of the present embodiment uniformly packs the packaging sheet P immediately after the final package HL formed on the most upstream side in the conveying direction X among the plurality of packaged medicines is formed by the heat sealing apparatus 3. Transport 20mm. This 20 mm conveyance is performed regardless of the size in the longitudinal direction of the package containing medicine (in this embodiment, the longitudinal dimension is 60 mm). When this 20 mm conveyance is performed, the seals S1 and S2 and the perforations M are formed on the packaging sheet P by the heat sealing device 3. Thereby, the narrow empty package HEa is formed. The transport distance of 20 mm is merely an example and can be set arbitrarily.

  Then, the sheet conveying apparatus 4 of this embodiment conveys the packaging sheet P twice continuously for 60 mm. The seals S1 and S2 and the perforations M are formed on the packaging sheet P by the heat sealing device 3 every time this conveyance is performed. After the two times of conveyance, the perforation M located on the upstream side in the conveyance direction X in the narrow package HEa stops at the position of the cutting blade portion 7. Thereby, since the perforation M corresponds with the cutting blade part 7, a user can cut off the package H easily. For this reason, the package H can be cut out stably. Moreover, since the cut end of the package H coincides with the perforation M, the cut end can be made straight and beautiful. Further, the ease of cutting is less likely to vary depending on the material of the packaging sheet P.

  In the sheet conveying apparatus 4 of the present embodiment, the position at which the user cuts the package H can be shifted to the upstream side in the conveying direction X by 20 mm from the final package HL. For this reason, when the package H is cut out, the final package HL can be prevented from being accidentally damaged, and the medicine can be prevented from spilling out.

  In the present embodiment, as described above, the packaging sheet P is transported twice continuously for 60 mm, and as a result, 120 mm is transported. This 120 mm coincides with the distance from the formation position of the short-side seal S1 in the heat seal device 3 to the cutting blade portion 7, and is a unique dimension in the drug packaging device A of the present embodiment. Two empty packets HE are formed so that this unique dimension (120 mm) is divided into two equal parts of 60 mm. However, the breakdown of the conveyance for 120 mm is not limited. For example, the conveyance for 40 mm and the conveyance for 80 mm can be combined, or the conveyance for 120 mm can be performed once, in addition to performing 60 mm twice as in this embodiment. You may do it. Furthermore, the conveyance of 140 mm including the conveyance of 20 mm and the conveyance of 120 mm may be performed without forming the short-side seal S1 in the middle. Further, the above-mentioned equal division may be divided into various equal divisions other than bisection, and it is only necessary to finally carry 120 mm. In the present embodiment, 20 mm, 60 mm, and 60 mm are sequentially conveyed after the final packet HL (60 mm) is formed.

  In this embodiment, 140 mm obtained by adding 20 mm of the narrow empty package HEa to 120 mm, which is a unique dimension in the medicine packaging apparatus A, is a section that does not contribute to medicine packaging (a section where medicine cannot be packaged). As described above, 60, 70, 80, and 90 mm can be selected as the longitudinal interval at which the heat seal device 3 forms the short-side seal S1. Here, as in the conventional case, if an empty package having the same longitudinal dimension as the final package HL is formed, 60 × 3−140 = 40 in the case of 60 mm, and the packaging sheet P can be saved by 40 mm in this embodiment. In the case of 80 mm, 80 × 2−140 = 20, and the packaging sheet P can be saved by 20 mm. In the case of 90 mm, 90 × 2−140 = 40, and the packaging sheet P can be saved by 40 mm. However, only in the case of 70 mm, since 70 × 2−140 = 0, the packaging sheet P is not saved. However, if the average value in each setting is evaluated, the packaging sheet P can be saved by 25 mm. That is, the medicine packaging apparatus A of the present embodiment can reduce waste of the packaging sheet P compared to the conventional medicine packaging apparatus.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the summary of this invention.

  For example, instead of the wrapping sheet P in a folded state, two opposing long strip-shaped wrapping sheets may be used. In this case, it is necessary to heat-seal or press the lower end edge in the longitudinal direction before putting the medicine so that the medicine thrown from the medicine feeding section 2 does not leak out. .

  Moreover, although the heat seal apparatus of this embodiment shall have a pair of substantially L-shaped seal part 30, it is not restricted to this, A seal | sticker part may be various rod shape, plane shape, and frame shape. . Further, the seal portion may be a roller.

  Moreover, in this embodiment, although it was set as the heat sealing apparatus 3 which performs heat sealing as a sealing apparatus, you may seal using an adhesive agent etc. other than heat sealing.

  Further, in this embodiment, the perforation forming unit 34 is provided in the heat seal device 3 and the perforation forming unit 34 is controlled together with the pair of seal units 30 by the control unit CONT. It may be provided separately from the sealing device 3 and may be controlled separately from the pair of sealing portions 30 by the control unit CONT.

  Further, in the present embodiment, the sheet conveying device 4 conveys the packaging sheet P so that the perforation M stops at the position of the cutting blade portion 7, but the present invention is not limited to this, and the sheet conveying device 4 The packaging sheet P may be transported regardless of the position of the blade portion 7.

  Further, the sheet conveying device 4 of the present embodiment conveys the packaging sheet P so that the perforation M located upstream in the conveying direction X in the narrow empty package HEa stops at the position of the cutting blade portion 7. The packaging sheet P may be transported such that the perforation M located on the downstream side in the transport direction X in the empty package HEa stops at the position of the cutting blade portion 7.

  Moreover, although the said mechanism is used for the medicine packaging apparatus A in this embodiment, this is an example to the last, and can be widely used for the apparatus for packaging goods other than the medicine packaging apparatus A. .

  Finally, the configuration and operation of the present invention will be summarized.
