DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, the embodiments will be described with reference to the drawings. In the following description, the same parts and components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated. In the drawings, configurations may be omitted or simplified for convenience of explanation. It is also intended from the beginning that any configurations may be extracted from the embodiments and arbitrarily combined.

[0012] <Packaging device 1> FIG. 1 is a schematic configuration diagram of a packaging device 1 according to an embodiment.

[0013] The packaging device 1 is used to package an object to be packaged. The object to be packaged is a medicine, specifically, a solid medicine. Examples of the solid medicine include powders, granules, tablets, pills, and capsules. The object to be packaged is not limited to a solid medicine. The object to be packaged may be a semi-solid medicine or a liquid medicine.

[0014] The packaging device 1 is a drug packaging device for packaging drugs based on a prescription. A prescription is issued by a doctor to a patient. The prescription contains patient information and drug information. The patient information includes the patient's name and age. The drug information includes the drug name, amount, usage, and dosage. The packaging device 1 is used to package drugs into single dose amounts based on such a prescription.

[0015] A packaging material roll 3 is attached to the packaging device 1. The packaging material roll 3 is a packaging material 2 wound in a roll shape. The packaging material 2 is in the form of a long sheet. The packaging material 2 is formed, for example, from a resin film material. The packaging material 2 may be formed, for example, by laminating polyethylene onto OPP (biaxially oriented polypropylene).

[0016] The packaging device 1 is equipped with a packaging material conveying section 8. The packaging material conveying section 8 applies a driving force to the packaging material 2 to convey the packaging material 2. The packaging material 2 is conveyed in the longitudinal direction of the packaging material 2. The packaging material 2 is sent out from the packaging material roll 3. The arrow in FIG. 1 indicates the conveying direction DR of the packaging material 2. Hereinafter, the conveying direction DR of the packaging material 2 will be simply referred to as the "conveying direction DR." The upstream side of the conveying direction DR (the side closer to the packaging material roll 3) will be simply referred to as the "upstream." The downstream side of the conveying direction DR (the side away from the packaging material roll 3) will be simply referred to as the "downstream."

[0017] The packaging device 1 includes a packaging section 9. The packaging section 9 includes a medicine supplying section 5, a container forming section 6, and a perforation forming section .

[0018] The medicine supplying unit 5 supplies medicine to the packaging material 2 transported by the packaging material transporting unit 8. The medicine is supplied at one dose based on the prescription. The container forming unit 6 forms a container using the packaging material 2 transported by the packaging material transporting unit 8. The medicine is stored in the container. After the medicine is supplied from the medicine supplying unit 5, the container forming unit 6 heat seals the packaging material 2. The container forming unit 6 individually packages the medicine supplied from the medicine supplying unit 5 for one dose, and forms a packaging bag that is a package with the medicine contained inside.

[0019] The perforation forming section 7 is provided in the storage section forming section 6. The perforation forming section 7 forms perforations extending in a direction perpendicular to the conveying direction DR in the packaging material 2 conveyed by the packaging material conveying section 8. The perforations are a plurality of small holes arranged continuously in the short direction of the packaging material 2. The perforations are formed at positions that separate adjacent packaging bags in the longitudinal direction of the packaging material 2. By cutting the packaging material 2 along the perforations, the adjacent packaging bags can be easily separated.

[0020] The packaging device 1 further includes a printing unit 4. The printing unit 4 affixes a predetermined marking to the packaging material 2 that is unwound from the packaging material roll 3 and conveyed by the packaging material conveying unit 8. The predetermined marking is information related to the medicine contained in the packaging bag. The printing unit 4 is disposed upstream of the packaging unit 9 in the conveying direction of the packaging material 2. The printing unit 4, the medicine supplying unit 5, and the containing section forming unit 6 are arranged in this order from upstream to downstream in the conveying direction DR. The printing unit 4 prints information related to the medicine on the packaging material 2 prior to the heat fusion of the packaging material 2 by the containing section forming unit 6. The information related to the medicine includes the name and age of the person taking the medicine, the time of taking the medicine (dosage), the name and amount (quantity, weight) of the medicine, and the like.

[0021] FIG. 2 is a schematic perspective view of the medicine supplying section 5 and the container forming section 6 in the packaging device 1 shown in FIG.

[0022] At the drug supply position where the drug supply unit 5 supplies the drug 100 to the packaging material 2, the packaging material 2 is folded in half along the center line in the short side direction of the packaging material 2. Both short side edge portions 2a of the packaging material 2 are located above the short side central portion 2b of the packaging material 2 and are spaced apart from each other. As a result, an opening 2c facing upward is formed in the packaging material 2.

[0023] The packaging material 2 may be folded in half in advance. In this case, the packaging material 2 folded in half is fed from a packaging material roll 3 on which the packaging material 2 folded in half in advance is wound in a roll shape.

[0024] Alternatively, the packaging material 2 may be folded in half along the conveying path. In this case, the packaging material 2 is wound into a roll without being folded in half. The packaging material 2 is fed out from the packaging material roll 3 thus manufactured. A mechanism for folding the packaging material 2 in half is provided upstream of the drug supply position. The packaging material 2 fed out from the packaging material roll 3 is folded in half upstream of the drug supply position.

[0025] The drug supply unit 5 has a supply unit main body (not shown) and a hopper 51. The supply unit main body supplies the drug 100. The hopper 51 guides the drug 100 supplied from the supply unit main body to the packaging material 2. The hopper 51 has, at its tip, a drug inlet 52 for injecting the drug 100 into the packaging material 2. The drug inlet 52 is disposed so as to enter the inside of the packaging material 2 folded in half. The drug 100 supplied from the supply unit main body is guided by the hopper 51 to pass through the opening 2c of the packaging material 2 and enter the inside of the packaging material 2 folded in half.

[0026] The storage section forming section 6 has a heating member 61, a receiving member 62, and a pressure motor 65. The heating member 61 has a built-in heater. The receiving member 62 is a member that receives the heating member 61. The heating member 61 and the receiving member 62 are disposed opposite each other with the packaging material 2 sandwiched therebetween. The pressure motor 65 drives the heating member 61 and the receiving member 62. The heating member 61 and the receiving member 62 driven by the pressure motor 65 pressurize the packaging material 2 from both sides and separate them from the packaging material 2.

[0027] The heating member 61 and the receiving member 62 are each substantially T-shaped. The heating member 61 and the receiving member 62 each have a longitudinal portion 63 and a transverse portion 64. The longitudinal portion 63 constitutes a horizontal bar portion of the T and extends in the longitudinal direction of the packaging material 2. The longitudinal portion 63 extends in the conveying direction DR. The transverse portion 64 constitutes a vertical bar portion of the T and extends in the transverse direction of the packaging material 2. The transverse portion 64 extends in a direction perpendicular to the conveying direction DR. The longitudinal portion 63 of the heating member 61 and the longitudinal portion 63 of the receiving member 62 are disposed opposite each other with the packaging material 2 therebetween. The transverse portion 64 of the heating member 61 and the transverse portion 64 of the receiving member 62 are disposed opposite each other with the packaging material 2 therebetween.

[0028] In the container forming section 6, the heating member 61 is heated by a heater. In this state, the heating member 61 and the receiving member 62 pressurize the packaging material 2 from both sides. As a result, a longitudinal fused portion 23 and a transverse fused portion 24 are formed in the packaging material 2. The longitudinal fused portion 23 is formed by heat-sealing a portion of the packaging material 2 sandwiched between the longitudinal portion 63 of the heating member 61 and the longitudinal portion 63 of the receiving member 62. The longitudinal fused portion 23 closes the opening 2c of the packaging material 2. The transverse fused portion 24 is formed by heat-sealing a portion of the packaging material 2 sandwiched between the transverse portion 64 of the heating member 61 and the transverse portion 64 of the receiving member 62. The transverse fused portion 24 divides the inside of the packaging material 2 into a downstream side and an upstream side.

[0029] As a result, the packaging material 2 is divided by the crease of the folded packaging material 2, the longitudinal fused portion 23, and the two transverse fused portions 24 aligned in the conveying direction DR, forming sachets 21. The transverse fused portions 24 form the boundary between adjacent sachets 21 in the longitudinal direction of the packaging material 2. A storage section 22 is formed inside the sachet 21, and the drug 100 is stored in the storage section 22. The storage section 22 stores the drug 100, which is the object to be packaged.

[0030] The packaging material 2 does not necessarily have to be folded in half. Two different packaging material rolls may be attached to the packaging device 1, two sheets of packaging material unwound from the two packaging material rolls may be overlapped, and after a medicine is placed between the two sheets of packaging material, the two sheets of packaging material may be heat-sealed to form the sachet 21.

[0031] Fig. 3 is a schematic diagram showing a schematic configuration of the perforation forming unit 7 in the packaging device 1 shown in Fig. 1. Fig. 3(A) shows the arrangement of the perforation forming unit 7 when the perforation 25 is not formed in the packaging material 2. Fig. 3(B) shows the arrangement of the perforation forming unit 7 when the perforation 25 is formed in the packaging material 2.

[0032] As shown in FIG. 3(A), the perforation forming section 7 has a perforation forming blade 71. The perforation forming blade 71 is provided in the short side portion 64 of the receiving member 62. The perforation forming blade 71 is located in the widthwise center of the short side portion 64 of the receiving member 62. The perforation forming blade 71 extends in the short side direction of the packaging material 2 as a whole. The heating member 61 has a slit groove 72 formed by recessing a part of the surface facing the packaging material 2. The slit groove 72 extends in the short side direction of the packaging material 2.

[0033] The perforation forming blade 71 is pressed against the packaging material 2 when the heating member 61 and the receiving member 62 pressurize the packaging material 2 from both sides. The blade tip of the perforation forming blade 71 protrudes from the receiving member 62 and penetrates the packaging material 2 in the thickness direction, thereby forming a perforation 25 in the packaging material 2. At this time, the blade tip of the perforation forming blade 71 moves to the inside of the slit groove 72 as shown in FIG. 3(B). The perforation forming blade 71 is driven by the pressure motor 65 like the heating member 61 and the receiving member 62, and moves relative to the receiving member 62. The perforation 25 is formed in the center in the width direction of the short-side fused portion 24. By cutting the packaging material 2 along the perforation 25, adjacent sachets 21 can be easily separated.

[0034] The perforation forming blade 71 does not have to be provided on the receiving member 62. For example, the perforation forming blade 71 arranged downstream of the storage portion forming unit 6 may be configured to form the perforation 25 in the width direction center of the already formed short-side fusion portion 24. In this case, the perforation forming unit 7 further has, in addition to the perforation forming blade 71, a drive unit for driving the perforation forming blade 71.

[0035] Returning to Fig. 2, the packaging material conveying section 8 has a pair of conveying rollers 81 and a conveying motor 82. The pair of conveying rollers 81 are disposed opposite each other with the packaging material 2 sandwiched therebetween. The conveying motor 82 drives and rotates the pair of conveying rollers 81. The conveying motor 82 drives and rotates the pair of conveying rollers 81, whereby the packaging material 2 is conveyed.

[0036] In such a packaging section 9 (FIG. 1), the packaging material conveying section 8 conveys the packaging material 2 intermittently. When the conveyance of the packaging material 2 is stopped, the heating member 61 and the receiving member 62 pressurize the packaging material 2 from both sides. At this time, the perforation forming blade 71 is pressed against the packaging material 2. As a result, in the packaging material 2, longitudinal fused portions 23 are formed so as to be continuous in the longitudinal direction of the packaging material 2, transverse fused portions 24 are formed at regular intervals in the longitudinal direction of the packaging material 2, and further perforations 25 are formed at regular intervals in the longitudinal direction of the packaging material 2. In this manner, a plurality of sachets 21 are formed in the longitudinal direction of the packaging material 2.

[0037] Sachet 21 is a portion between adjacent short-side fused portions 24 in the longitudinal direction of packaging material 2, and is a portion between adjacent perforations 25 in the longitudinal direction of packaging material 2. Short-side fused portions 24 form the boundary between adjacent sachet bags 21 in the longitudinal direction of packaging material 2. Short-side portion 64 of heating member 61 and short-side portion 64 of receiving member 62 form the boundary between sachet bags 21 aligned in the conveying direction DR.

[0038] Here, the length between the widthwise central portions of adjacent short-side fused portions 24 in the conveying direction DR is referred to as the width W of the sachet 21 in the conveying direction DR. The width W indicates the length between adjacent perforations 25 in the longitudinal direction of the packaging material 2.

[0039] <Perforation blade 71> 4 is a perspective view showing the configuration of the perforation forming blade body 71. The perforation forming blade body 71 includes a perforation forming blade 110 and a notch forming blade 200.

[0040] FIG. 5 is a perspective view of the perforation forming blade 110. The perforation forming blade 110 includes a base 120 and a plurality of blade portions 130. Each of the plurality of blade portions 130 protrudes from the base 120. The plurality of blade portions 130 are arranged in a line. The Z direction shown in FIG. 4 is the direction in which the blade portion 130 protrudes from the base 120, and is hereinafter referred to as the protruding direction. The X direction shown in FIG. 4 is the direction in which the plurality of blade portions 130 are arranged, and is hereinafter referred to as the arrangement direction. The arrangement direction is perpendicular to the protruding direction. The Y direction shown in FIG. 4 is the direction perpendicular to the protruding direction and the arrangement direction, and is hereinafter referred to as the orthogonal direction.

[0041] The base 120 has a flat plate shape extending in the protruding direction and in the arranging direction. When looking at the perforation forming blade 110 in the perpendicular direction, the base 120 has a generally rectangular shape as a whole. The base 120 has a first base surface 121 which is one surface, and a second base surface 122 which is the other surface opposite to the first base surface 121.

[0042] Each of the multiple blade portions 130 protrudes from the base portion 120 in a protruding direction. The multiple blade portions 130 are aligned in an alignment direction. A groove portion 150 is formed between two blade portions 130 adjacent to each other in the alignment direction. The two blade portions 130 adjacent to each other in the alignment direction are separated from each other by the groove portion 150.

[0043] Each of the multiple blade portions 130 has a flat first blade surface 131 and a flat second blade surface 132 on the front surface side shown in Fig. 5. Each of the multiple blade portions 130 has a flat third blade surface 133 and a flat fourth blade surface 134 (see Fig. 8) on the back surface side opposite the front surface.

[0044] An attachment groove portion 170 is formed between a pair of blade portions 130 among two blade portions 130 adjacent to each other in the arrangement direction. The first side surface 171 and the second side surface 172 form the side surfaces of the groove. The first side surface 171 and the second side surface 172 extend parallel to each other and are arranged at an interval in the arrangement direction. The first side surface 171 and the second side surface 172 extend in the YZ plane in the Cartesian coordinate system shown in FIG. 4. The bottom surface 173 forms the bottom surface of the groove. The bottom surface 173 extends in the XY plane in the Cartesian coordinate system shown in FIG. 4. The first side surface 171 and the second side surface 172 are perpendicular to the bottom surface 173.

[0045] 4, the incision forming blade 200 is attached to the attachment groove portion 170. An assembly groove 124 is formed in the base portion 120. The assembly groove 124 is used to assemble the incision forming blade 200 to the perforation forming blade 110.

[0046] The perforation forming blade 110 further includes an auxiliary blade portion 160. The auxiliary blade portion 160 is provided at one end of the multiple blade portions 130 aligned in the alignment direction. The perforation forming blade 110 has a comb-like shape as a whole.

[0047] 6 is a perspective view of the incision forming blade 200. The incision forming blade 200 has an attachment portion 210, a base portion 220, and a blade portion 230.

[0048] The mounting portion 210 has a rectangular plate-like outer shape. A circular mounting hole 212 is formed penetrating the mounting portion 210. The mounting portion 210 is used to mount the incision forming blade 200 to the perforation forming blade 110. When the incision forming blade 200 is mounted to the perforation forming blade 110, the mounting portion 210 extends on the YZ plane in the Cartesian coordinate system shown in FIG.

[0049] The base 220 has a rectangular columnar shape. The base 220 is connected to the mounting part 210 at its lower end. The base 220 has four side surfaces and a lower surface 225. The base 220 has a flat first side surface 221, a flat second side surface 222, a flat third side surface 223, and a flat fourth side surface 224. The first side surface 221 and the third side surface 223 are parallel to each other. The second side surface 222 and the fourth side surface 224 are parallel to each other. The second side surface 222 and the fourth side surface 224 are perpendicular to the first side surface 221.

[0050] The blade portion 230 is provided at the tip of the base portion 220. The tip of the base portion 220 is machined to form the blade portion 230. The blade portion 230 has a flat first blade surface 231 and a flat second blade surface 232. The incision forming blade 200 has a cutting edge 230P that forms the apex of the incision forming blade 200. The first blade surface 231, the second blade surface 232, and the third side surface 223 form the cutting edge 230P.

[0051] The ridge where the first blade surface 231 and the second blade surface 232 intersect constitutes the first cutting edge 241. The ridge where the first blade surface 231 and the third side surface 223 intersect constitutes the second cutting edge 242. The ridge where the second blade surface 232 and the third side surface 223 intersect constitutes the third cutting edge 243. The first cutting edge 241 and the second cutting edge 242 intersect at the cutting edge 230P and form an acute angle. The first cutting edge 241 and the third cutting edge 243 intersect at the cutting edge 230P and form an acute angle. The second cutting edge 242 and the third cutting edge 243 intersect at the cutting edge 230P and form an acute angle.

[0052] When the incision forming blade 200 is attached to the perforation forming blade 110, the extending direction of the base 220 becomes the protruding direction. The first cutting edge 241, the second cutting edge 242, and the third cutting edge 243 are inclined with respect to the extending direction of the base 220. The thickness of the blade portion 230 of the incision forming blade 200 gradually decreases toward the cutting edge 230P.

[0053] The angle at which the second cutting edge 242 is inclined relative to the extension direction of the base 220 is greater than the angle at which the first cutting edge 241 is inclined relative to the extension direction of the base 220. The angle at which the third cutting edge 243 is inclined relative to the extension direction of the base 220 is greater than the angle at which the first cutting edge 241 is inclined relative to the extension direction of the base 220.

[0054] The ridge line where the first blade surface 231 and the second side surface 222 intersect with each other constitutes a fourth ridge line 244. The ridge line where the second blade surface 232 and the fourth side surface 224 intersect with each other constitutes a fifth ridge line 245.

The first blade surface 131 and the second blade surface 132 are symmetrical with respect to the third blade edge 143. The third blade surface 133 and the fourth blade surface 134 intersect at the center of the blade portion 130 in the arrangement direction. The ridge line where the third blade surface 133 and the fourth blade surface 134 intersect with each other constitutes the fourth blade edge 144. The third blade surface 133 and the fourth blade surface 134 are symmetrical with respect to the fourth blade edge 144.

[0061] The first cutting edge 141 and the second cutting edge 142 extend on the XZ plane in the Cartesian coordinate system shown in Fig. 4. The first cutting edge 141 and the second cutting edge 142 are perpendicular to each other in the perpendicular direction. The first cutting edge 141 and the second cutting edge 142 intersect at the cutting edge 130P and form an acute angle. The first cutting edge 141 and the second cutting edge 142 intersect at the center of the blade portion 130 in the arrangement direction. The angle at which the first cutting edge 141 is inclined with respect to the protruding direction and the angle at which the second cutting edge 142 is inclined with respect to the protruding direction are equal to each other.

[0062] The third cutting edge 143 and the fourth cutting edge 144 extend on the YZ plane in the Cartesian coordinate system shown in Fig. 4. The third cutting edge 143 and the fourth cutting edge 144 are perpendicular to the arrangement direction. The third cutting edge 143 and the fourth cutting edge 144 intersect at the cutting edge 130P and form an acute angle. The third cutting edge 143 and the fourth cutting edge 144 intersect at the center of the blade portion 130 in the perpendicular direction. The angle at which the third cutting edge 143 is inclined with respect to the protruding direction and the angle at which the fourth cutting edge 144 is inclined with respect to the protruding direction are equal to each other.

[0063] The angle at which first cutting edge 141 and second cutting edge 142 are inclined relative to the protruding direction is greater than the angle at which third cutting edge 143 and fourth cutting edge 144 are inclined relative to the protruding direction. The angle between first cutting edge 141 and second cutting edge 142 is greater than the angle between third cutting edge 143 and fourth cutting edge 144.

[0064] The first blade surface 131 and the second blade surface 132 extend from the cutting tip 130P toward the first base surface 121 of the base 120 so as to be inclined with respect to the protruding direction and with respect to the arranging direction. The ridge line where the first blade surface 131 and the first base surface 121 intersect with each other constitutes a fifth ridge line 145. The ridge line where the second blade surface 132 and the first base surface 121 intersect with each other constitutes a sixth ridge line 146.

[0065] The third blade surface 133 and the fourth blade surface 134 extend from the cutting tip 130P toward the second base surface 122 of the base 120 so as to be inclined with respect to the protruding direction and with respect to the arranging direction. The ridge line where the third blade surface 133 and the second base surface 122 intersect with each other constitutes a seventh ridge line 147. The ridge line where the fourth blade surface 134 and the second base surface 122 intersect with each other constitutes an eighth ridge line 148.

[0066] The first blade surface 131 and the fourth blade surface 134 have the same shape. The first blade surface 131 and the fourth blade surface 134 are formed in a shape symmetrical by 180° with respect to a symmetric axis that passes through the cutting edge 130P and extends in the protruding direction. The second blade surface 132 and the third blade surface 133 have the same shape. The second blade surface 132 and the third blade surface 133 are formed in a shape symmetrical by 180° with respect to a symmetric axis that passes through the cutting edge 130P and extends in the protruding direction. When the blade portion 130 is viewed in the protruding direction, the first blade surface 131, the second blade surface 132, the third blade surface 133, and the fourth blade surface 134 have a congruent rectangular shape.

[0067] When the incision forming blade 200 is assembled to the perforation forming blade 110, the base 220 of the incision forming blade 200 extends in the protruding direction. The lower surface 225 of the base 220 is in surface contact with the bottom surface 173 of the mounting groove 170. The base 220 of the incision forming blade 200 and the blade portion 230 at the tip of the base 220 are mounted on the bottom surface 173 of the mounting groove 170. The base 220 and the blade portion 230 of the incision forming blade 200 are accommodated in the mounting groove 170. The first side surface 221 and the third side surface 223 of the incision forming blade 200 extend in the YZ plane in the orthogonal coordinate system shown in FIG. 4. The second side surface 222 and the fourth side surface 224 extend in the XZ plane in the orthogonal coordinate system shown in FIG. 4.

[0068] When the incision forming blade 200 is attached to the perforation forming blade 110, the first blade surface 231 and the second blade surface 232 extend from the cutting edge 230P toward the base 220 so as to be inclined with respect to the protruding direction, the arrangement direction, and the orthogonal direction. The third side surface 223 extends from the cutting edge 230P so as to be orthogonal to the arrangement direction. The incision forming blade 200 has a shape that extends in the orthogonal direction as a whole.

[0069] When the incision forming blade 200 is assembled to the perforation forming blade 110, the first cutting edge 241 extends on the XZ plane in the orthogonal coordinate system shown in FIG. 4. The first cutting edge 241 is inclined with respect to the protruding direction, inclined with respect to the arrangement direction, and extends perpendicular to the orthogonal direction. The first cutting edge 241 of the incision forming blade 200 and the first cutting edge 141 and the second cutting edge 142 of the perforation forming blade 110 are on the same plane. The second cutting edge 242 and the third cutting edge 243 extend on the YZ plane in the orthogonal coordinate system shown in FIG. 4. The second cutting edge 242 and the third cutting edge 243 are perpendicular to the arrangement direction. When the blades 130, 230 are viewed in the protruding direction, the second cutting edge 242 and the third cutting edge 243 of the incision forming blade 200 are perpendicular to the first cutting edge 141 of the perforation forming blade 110.

[0070] The attachment groove 170 is formed by cutting out a part of the blade portion 130. The attachment groove 170 is formed across two adjacent blade portions 130.

[0071] One blade portion 130X of two adjacent blade portions 130 (blade portion 130X, blade portion 130Y) cut out to form the mounting groove portion 170 has a first blade surface 131A and a third blade surface 133A. The other blade portion 130Y of two adjacent blade portions 130 (blade portion 130X, blade portion 130Y) cut out to form the mounting groove portion 170 has a second blade surface 132A and a fourth blade surface 134A. The first blade surface 131A has an area smaller than the first blade surface 131 of the other blade portion 130 that is not cut out. The second blade surface 132A, the third blade surface 133A, and the fourth blade surface 134A have areas smaller than the second blade surface 132, the third blade surface 133, and the fourth blade surface 134 of the other blade portion 130 that is not cut out, respectively.

[0072] When the incision forming blade 200 is attached to the perforation forming blade 110, the third side surface 223 of the incision forming blade 200 contacts the blade portion 130 of the perforation forming blade 110. The second side surface 172 of the mounting groove portion 170 forms a side wall surface of the blade portion 130X. The third side surface 223 of the incision forming blade 200 is in surface contact with the side wall surface of the blade portion 130X.

[0073] On the other hand, the first side surface 221 of the incision forming blade 200 is disposed away from the blade portion 130Y. The first side surface 171 of the mounting groove portion 170 constituting the side wall surface of the blade portion 130Y and the first side surface 221 of the incision forming blade 200 are separated in the arrangement direction. A gap is formed between the first side surface 171 and the first side surface 221.

[0074] When the incision forming blade 200 is attached to the perforation forming blade 110, the cutting tip 130P of the perforation forming blade 110 and the cutting tip 230P of the incision forming blade 200 are at the same position in the protruding direction. When the perforation 25 is formed in the packaging material 2 using the perforation forming blade body 71 shown in Fig. 3, the cutting tip 130P of the perforation forming blade 110 and the cutting tip 230P of the incision forming blade 200 come into contact with the packaging material 2 at almost the same time.

[0075] When the incision forming blade 200 is assembled to the perforation forming blade 110, the lower ends of the third blade edge 143 and the fourth blade edge 144 of the perforation forming blade 110 and the lower end of the first blade edge 241 of the incision forming blade 200 are in the same position in the protruding direction. When the incision forming blade 200 is assembled to the perforation forming blade 110, the lower ends of the first blade surface 131, the second blade surface 132, the third blade surface 133 and the fourth blade surface 134 of the perforation forming blade 110 and the lower ends of the first blade surface 231 and the second blade surface 232 of the incision forming blade 200 are in the same position in the protruding direction.

[0076] FIG. 10 is a perspective view showing a structure for fixing the incision forming blade 200 to the perforation forming blade 110. The mounting member 280 is arranged so as to contact the first base surface 121 of the base 120 of the perforation forming blade 110. The fixing member 281 is arranged penetrating the mounting member 280 and further penetrating the mounting groove 124 (FIG. 5) to fix the mounting member 280 to the perforation forming blade 110. The fixing member 282 is fixed to the mounting member 280 by penetrating the mounting hole 212 (FIG. 6) formed in the mounting portion 210 of the incision forming blade 200. The incision forming blade 200 and the perforation forming blade 110 are fixed together via the mounting member 280 and the fixing members 281, 282. The incision forming blade 200 and the perforation forming blade 110 constitute a perforation forming blade body 71 having an integral structure.

[0077] <21 sachets, 25 perforations> 11 is a schematic diagram showing a sachet 21 on which a perforation 25 is formed. The fold of the packaging material 2 folded in half, the longitudinal fusion part 23, and the transverse fusion part 24 divide the packaging material 2 to form the sachet 21. A storage part 22 is formed inside the sachet 21, and the medicine is stored in the storage part 22. The sachet 21 packs the medicine, which is the packaging object, in one package at a time.

[0078] FIG. 12 is a schematic diagram showing an enlarged view of region XII shown in FIG. 11. Referring also to FIG. 3, a dividing region 26 where the packaging material 2 is not heat-sealed is provided between two adjacent short-side fused portions 24. A perforation-forming blade 71 is interposed between two receiving members 62. When the heating member 61 and the receiving member 62 heat and press the packaging material 2 to form the short-side fused portion 24, the perforation-forming blade 71 is pressed against the packaging material 2 to form a perforation 25 in the dividing region 26. The two short-side fused portions 24 and the dividing region 26 sandwiched therebetween shown in FIG. 12 constitute a partitioning portion 27 that separates two sachets 21 adjacent in the longitudinal direction of the packaging material 2. The perforation 25 is formed in the partitioning portion 27.

[0079] The perforations 25 include a dividing perforation 251. In Figs. 11 and 12, the up-down direction in the drawings is the short side direction of the packaging material 2. The dividing perforation 251 includes a plurality of pores extending in the short side direction of the packaging material 2. The plurality of pores are continuously lined up in the short side direction of the packaging material 2. The plurality of pores are formed in a line with intervals between them in the short side direction of the packaging material 2. The plurality of pores are lined up on an imaginary straight line extending in the short side direction of the packaging material 2.

[0080] The perforation 25 further includes an opening cutout 255. In Figs. 11 and 12, the left-right direction in the drawings is the longitudinal direction of the packaging material 2. The opening cutout 255 is formed in the dividing region 26 so as to extend in the longitudinal direction of the packaging material 2. The opening cutout 255 extends in a direction perpendicular to the direction in which the pores extend. The opening cutout 255 is continuous with an end of one of the multiple pores. The pore to which the opening cutout 255 is continuous and the opening cutout 255 form an inverted T-shape.

[0081] 11, a separation start portion 25A at the lower end of the separation perforation 251 is formed by the auxiliary blade portion 160 (FIGS. 4 and 5). The separation start portion 25A is formed on the straight line on which the separation perforations 251 are aligned. The separation start portion 25A and the separation perforations 251 are aligned continuously in the short side direction of the packaging material 2. The separation start portion 25A is formed so as to reach the lower end of the sachet 21.

[0082] When the sachet 21 is divided along the perforation 25, the division start portion 25A is the division start portion. The handler who divides the sachet 21 holds one of the two adjacent sachet 21 between the fingers of the right hand and the other between the fingers of the left hand, and moves the two sachet 21 held in both hands away from each other so as to tear the perforation 25 from the division start portion 25A, thereby dividing the two adjacent sachet 21 along the perforation 25. In Figs. 11 and 12, the division start portion 25A is formed at the lower end of the sachet 21, so that the direction in which the sachet 21 is divided is the upward direction in the drawings. As shown in Fig. 12, each of the multiple pores of the division perforation 251 has an upstream end and a downstream end in the direction in which the sachet 21 is divided, and the opening cut portion 255 is continuous with the upstream end of one of the multiple pores.

[0083] Each divided sachet 21 has an opening slit 255 formed on both the left and right edges. A handler who wishes to open the sachet 21 can open the sachet 21 by holding the upper part of the opening slit 255 between the fingers of one hand and the lower part of the opening slit 255 between the fingers of the other hand, and tearing the sachet 21 from the opening slit 255. The handler can remove the medicine contained in the container 22 from the opened sachet 21.

[0084] Since the opening cutouts 255 are formed on both edges of the sachet 21, the opening direction is not limited to either the left or right direction. The direction in which the sachet 21 is cut when opening the sachet 21 may be either the left or right direction. The sachet 21 is configured to be openable from either the left or right direction.

[0085] Since the opening slit 255 is formed at only one location in the up-down direction of the sachet 21, the handler opens the sachet 21 from that one location. As described above, the packaging device 1 is provided with the printing unit 4, and it is possible to mark the sachet 21 with a predetermined marking by using the printing unit 4. For example, if a mark indicating the position of the opening slit 255 is marked on the sachet 21, the handler of the sachet 21 can easily open the sachet 21 from the opening slit 255. By marking the direction in which the sachet 21 is to be divided on the sachet 21, the handler of the sachet 21 can easily divide the sachet 21 from the division start portion 25A as the division start point.

[0086] <Action and Effects> Although there is some overlap with the above description, the characteristic configuration of this embodiment and its actions and effects can be enumerated as follows.

[0087] As shown in Figs. 11 and 12, in sachet bags 21 in which one package of packaging objects is packed, a dividing section 27 separating two adjacent sachet bags 21 has a dividing line 251 formed therein. The dividing line 251 has a plurality of pores extending in the short direction of the long sheet-like packaging material 2. The dividing line 251 is formed by continuously lining up the plurality of pores in the short direction of the packaging material 2. The sachet bag 21 is further formed with an opening slit 255 extending in the longitudinal direction of the packaging material 2. The opening slit 255 is continuous with an end of one of the plurality of pores constituting the dividing line 251.

[0088] After sachet 21 is divided along dividing perforations 251, opening slits 255 are formed on the edges of each sachet 21. Using these opening slits 255 as the starting point for opening, a user of sachet 21 can easily open sachet 21. Since opening slits 255 are formed on both edges of sachet 21, sachet 21 can be opened from any direction. This improves the ease of handling of sachet 21.

[0089] The fine holes constituting the dividing perforation 251 are connected to the opening cutout 255. The opening cutout 255 extends in a direction perpendicular to the direction in which the sachet 21 is divided. The sachet 21 is formed with perforations 25 such that, when dividing the sachet 21, the sachet 21 is less likely to tear toward the opening cutout 255 and is easier to divide along the dividing perforation 251. Since it is possible to prevent the sachet 21 from being opened accidentally when dividing the sachet 21, the handleability of the sachet 21 can be improved.

[0090] 11 and 12, the opening slit 255 is continuous with the upstream end of the hole in the direction in which two adjacent sachet bags 21 are separated along the separating perforation 251. The separating perforation 251 is formed so that the opening slit 255 is continuous with the upstream end of a pair of ends of the hole extending in the short direction of the packaging material 2 in the direction in which the sachet bag 21 is separated. This makes it possible to improve the resistance of the sachet bag 21 to tearing toward the opening slit 255 when the sachet bag 21 is separated, and reliably prevents the sachet bag 21 from being opened when the sachet bag 21 is separated.

[0091] As shown in Figs. 4, 7 to 9, the perforation forming blade body 71 includes a perforation forming blade 110 and an incision forming blade 200. The perforation forming blade 110 includes a plurality of blade portions 130 that protrude in a protruding direction from a plate-shaped base portion 120 and are aligned in an arranging direction. The incision forming blade 200 has a shape that extends in a perpendicular direction. As shown in Fig. 5, an attachment groove portion 170 is formed between two adjacent blade portions 130 of the perforation forming blade 110. The incision forming blade 200 is attached to the attachment groove portion 170.

[0092] When forming the perforation 25 in the packaging material 2, the perforation forming blade 71 is pressed against the packaging material 2. The cutting edge 130P of the blade portion 130 of the perforation forming blade 110 and the cutting edge 230P of the blade portion 230 of the incision forming blade 200 come into contact with the packaging material 2. The perforation forming blade 110 is pressed against the packaging material 2, and a fine hole extending in the short direction of the packaging material 2 is formed in the packaging material 2 along the first cutting edge 141 and the second cutting edge 142 of the blade portion 130. The incision forming blade 200 is pressed against the packaging material 2, and a fine hole extending in the long direction of the packaging material 2 is formed in the packaging material 2 along the second cutting edge 242 and the third cutting edge 243 of the blade portion 230. The perforation forming blade 71 is moved relatively in the thickness direction of the packaging material 2 until the fine hole formed by the perforation forming blade 110 and the fine hole formed by the incision forming blade 200 are connected. By using the perforation forming blade 71, the perforation 25 shown in Figures 11 and 12 can be reliably formed in the packaging material 2.

[0093] 3(B), when forming perforation 25 in packaging material 2, a portion of blade portion 130, 230 penetrates packaging material 2. The length by which blade portion 130, 230 penetrates packaging material 2 may be less than half the length from bottom surface 153 of groove portion 150 in the protruding direction to cutting tip 130P at the apex of blade portion 130. If blade portion 130, 230 penetrates packaging material 2 too far, packaging material 2 will tear too much, making it difficult to form perforation 25 in the intended shape. By appropriately setting the length by which blade portion 130, 230 penetrates packaging material 2, perforation 25 in the desired shape can be reliably formed.

[0094] 7 to 9, the incision forming blade 200 is attached to the perforation forming blade 110 in contact with one of the blade portions 130X of two adjacent blade portions 130. In this manner, the small hole formed by the first cutting edge 141 and the second cutting edge 142 of the blade portion 130 and the opening incision portion 255 formed by the second cutting edge 242 and the third cutting edge 243 of the blade portion 230 can be easily connected.

[0095] 7 to 9, the incision forming blade 200 is disposed away from the other blade portion 130Y of the two adjacent blade portions 130. In this manner, it becomes easy to form the opening incision portion 255 formed by the incision forming blade 200 so as to be continuous with only one of the multiple fine holes formed by the perforation forming blade 110.

[0096] 7 to 9, the first blade surface 231 and the second blade surface 232 of the incision forming blade 200 extend from the cutting tip 230P so as to be inclined with respect to the protruding direction, the arrangement direction, and the orthogonal direction. The third side surface 223 of the incision forming blade 200 extends from the cutting tip 230P so as to be orthogonal to the arrangement direction, and is in contact with the blade portion 130 of the perforation forming blade 110. By pressing the incision forming blade 200 having such a shape against the packaging material 2, it is possible to reliably form the opening incision portion 255 extending in the longitudinal direction of the packaging material 2.

[0097] 7 to 9, the ridge where the first blade surface 231 and the second blade surface 232 of the incision forming blade 200 intersect with each other forms the first blade edge 241. The first blade edge 241 is inclined with respect to the protruding direction, inclined with respect to the arrangement direction, and extends perpendicular to the orthogonal direction. By pressing the incision forming blade 200 having such a shape against the packaging material 2, it is possible to reliably form the opening incision portion 255 extending in the longitudinal direction of the packaging material 2.

[0098] 5, the mounting groove 170 is formed by cutting out a part of the blade portion 130. By mounting the incision forming blade 200 in the mounting groove 170 thus formed, the incision forming blade 200 can be reliably brought into contact with one of the two adjacent blade portions 130.

[0099] 5, the mounting groove 170 is formed across two adjacent blade portions 130. By mounting the incision forming blade 200 to the mounting groove 170 thus formed, the incision forming blade 200 can be reliably brought into contact with one of the two adjacent blade portions 130 and can be reliably positioned away from the other of the two adjacent blade portions 130.

[0100] 10, fixing members 281, 282 fix the perforation forming blade 110 and the incision forming blade 200. By fixing the perforation forming blade 110 and the incision forming blade 200 to form the perforation forming blade body 71 into an integrated structure, the perforation forming blade body 71 can be easily attached to and detached from the packaging device 1.

[0101] As shown in Figs. 1 to 3, the packaging device 1 includes a packaging unit 9. The packaging unit 9 uses a long sheet-like packaging material 2 to form sachets 21 in which the objects to be packaged are packaged one at a time. The packaging unit 9 includes a perforation forming blade 71. As shown in Figs. 11 and 12, the perforation forming blade 71 forms a perforation 25 in which a plurality of pores are continuously arranged in the short direction of the packaging material 2 in a partition section 27 that separates two sachets 21 adjacent to each other in the longitudinal direction of the packaging material 2. As shown in Figs. 4, 7 to 9, the perforation forming blade 71 includes a perforation forming blade 110 and a cut forming blade 200. The perforation forming blade 110 includes a plurality of blades 130 that protrude from a plate-like base 120 in the protruding direction and are arranged in the arranging direction. The cut forming blade 200 extends in the perpendicular direction. 5, an attachment groove portion 170 is formed between two adjacent blade portions 130 of the perforation forming blade 110. The incision forming blade 200 is attached to the attachment groove portion 170.

[0102] A packaging device 1 including such a perforation forming blade 71 can reliably form the perforations 25 shown in Figures 11 and 12 in the partitions 27 that separate the sachet 21 when forming the sachet 21.
