[0009] Hereinafter, an embodiment will be described with reference to the drawings. In the following drawings, the same or corresponding parts are designated by the same reference numerals, and the description thereof will not be repeated.

[0010] [First embodiment] <Configuration of drug packaging device A> First, a description will be given of a medicine packaging device A that packages medicines using a packaging sheet P as an example of a long sheet connected by a sheet connecting device according to an embodiment. Medicines such as powders, tablets, capsules, etc., of the type and quantity corresponding to a prescription are selectively supplied to the medicine packaging device A from a medicine distributing and supplying device (not shown) equipped with, for example, a dispensing box and a feeder. The medicine packaging device A packages the supplied medicines.

[0011] Fig. 1 is a schematic perspective view of a main part of a medicine packaging apparatus A. As shown in Fig. 1, the medicine packaging apparatus A includes a guide section 1, a medicine input section 2, a heat sealing device 3, and a sheet conveying device 4.

[0012] In the drug packaging device A, a long packaging sheet P is pulled out from a roll Q and guided to a guide section 1, and is transported in the longitudinal direction (the X direction in FIG. 1, which is also referred to as the transport direction of the packaging sheet P) by a sheet transport device 4. Drugs are added to the packaging sheet P in a drug input section 2, and the packaging sheet P is heat-sealed in a heat sealing device 3 to automatically package the drugs one by one. This forms a plurality of packages H that are individually partitioned and each contains a drug.

[0013] The roll body Q is a long strip-shaped packaging sheet P that is folded in half along the longitudinal direction and wound around a roll shaft R in a roll shape with an open end Pa formed in the longitudinal direction. Examples of the packaging sheet P that constitutes the roll body Q include glassine paper and resin sheets with a heat-sealable resin film layer. The edge on the side of the open end Pa may be subjected to an easy-to-cut processing such as forming minute scratches. The roll body Q is rotatably attached to the drug packaging device A.

[0014] Guide section 1 includes guide bar 11 and guide roller 12. As shown in Fig. 1, guide bar 11 and guide roller 12 are disposed such that their axial directions are aligned with the short-side direction of packaging sheet P. Guide bar 11 and guide roller 12 guide packaging sheet P unwound from roll body Q to medicine insertion section 2.

[0015] The guide section 1 also includes a triangular plate 14. The triangular plate 14 is located in the space inside the packaging sheet P that is folded in half. The triangular plate 14 has a substantially triangular shape in a plan view, and is wider than the width of the open end Pa of the packaging sheet P at the position of a medicine input hopper 21 described later. The triangular plate 14 is located downstream of the guide bar 11 in the conveying direction X and upstream of the medicine input 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 bar 11, and can correct any misalignment of the open end Pa of the packaging sheet P when it is sealed (so-called selvedge misalignment).

[0016] The drug input section 2 is equipped with a drug input hopper 21. The drug input hopper 21 receives a predetermined amount of drugs supplied from the drug distributing and supplying device, and inputs the drugs into a space within the packaging sheet P folded in half. The drug input hopper 21 has at its upper end a drug supply port 21b through which the drugs are supplied from the drug distributing and supplying device, and has at its lower end a drug input port 21a for inputting the supplied drugs into the packaging sheet P.

[0017] The medicine feeding hopper 21 is disposed through the open end Pa of the packaging sheet P opened by the triangular plate 14. The medicine feeding port 21a is located in the space within the packaging sheet P. This allows a predetermined amount of medicine supplied to the medicine packaging device A to be fed into the packaging sheet P without scattering.

[0018] The heat-sealing device 3 heat-seals (thermocompresses) the packaging sheet P conveyed by the sheet conveying device 4. As a result, individually partitioned packaging bodies H are formed. The heat-sealing device 3 has a pair of substantially L-shaped sealing units 30, each consisting of a short-side sealing unit 31 and a long-side sealing unit 32, and a drive unit that drives the pair of sealing units 30. The pair of sealing units 30 are disposed opposite each other with the packaging sheet P sandwiched between them. At least one of the pair of sealing units 30 is equipped with a heater. The pair of sealing units 30 equipped with a heater is heated while the pair of sealing units 30 holds the packaging sheet P folded in half, thereby heat-sealing the packaging sheet P and forming a series of a plurality of individually partitioned packaging bodies H.

[0019] The short-side seal portion 31 is disposed along the short side of the packaging sheet P, and extends slightly beyond the short-side end of the packaging sheet P folded in half. The short-side seal portion 31 forms a short-side seal S1 extending in the short-side direction in the packaging sheet P. The longitudinal seal portion 32 extends in the longitudinal direction of the packaging sheet P, and is located along the open end Pa of the packaging sheet P. The longitudinal seal portion 32 is formed to be longer than the length of one package of the package H formed in the packaging sheet P. The longitudinal seal portion 32 forms a longitudinal seal S2 extending in the longitudinal direction in the packaging sheet P. The short-side seal portion 31 is formed at the upstream end portion in the conveying direction X of the longitudinal seal portion 32.

[0020] A blade portion is provided on the inner surface of the short-side seal portion 31 on one side of the pair of seal portions 30. A receiving portion for receiving the blade portion is provided on the inner surface of the short-side seal portion 31 on the other side of the pair of seal portions 30. When the pair of seal portions 30 clamp the packaging sheet P, the blade portion protrudes from the inner surface of the short-side seal portion 31. As a result, perforations are formed in the packaging sheet P at the position of the short-side seal S1.

[0021] The sheet conveying device 4 conveys the packaging sheet P in the longitudinal direction (X direction in the figure). The sheet conveying device 4 has a pair of feed rollers 41 and a drive unit that rotates and drives the pair of feed rollers 41. The pair of feed rollers 41 rotate to convey the packaging sheet P in the longitudinal direction.

[0022] The medicine packaging device A further includes a dust collector 5 and a printer 6. As shown in FIG. 1, the dust collector 5 includes a shutter plate 51 having a partially cut-out dust collection port 51a, and an air suction device (not shown). In accordance with an instruction from an operator, the dust collector 5 covers the medicine supply port 21b of the medicine input hopper 21 except for the dust collection port 51a with the shutter plate 51, and sucks air from the dust collection port 51a with the air suction device. This cleans the medicine input hopper 21 of residual medicines, and collects dust from the medicine input hopper 21.

[0023] The printing device 6 prints information related to drug administration, such as the date and time of administration and the patient's name, at a position on the packaging sheet P corresponding to the package H into which the drug is to be placed, prior to the drug being placed. The printing device 6 is located upstream of the heat sealing device 3 in the sheet conveying direction X. The information related to drug administration is input by an input means (not shown) provided in the drug packaging device A, and is recorded in a memory means (not shown) also provided in the drug packaging device A.

[0024] <Configuration of seat connecting member 100> Next, a description will be given of a sheet connecting member 100 used to connect long sheets such as the packaging sheet P described with reference to Fig. 1. Fig. 2 is a front view showing a schematic configuration of the sheet connecting member 100.

[0025] The sheet connecting member 100 has a sheet-like shape having a front surface 101 shown in FIG. 2 and a back surface opposite to the front surface 101. The sheet connecting member 100 is made of paper, for example. The sheet connecting member 100 may be made of coated paper. The basis weight of the coated paper may be 110 kg or 135 kg. The sheet connecting member 100 may be made of synthetic paper made from resin. The thickness of the synthetic paper may be 110 μm or 130 μm.

[0026] If the sheet connecting member 100 is too soft, it is difficult to connect long sheets using the sheet connecting member 100. If the sheet connecting member 100 is too hard, the sheet connecting member 100 is difficult to fold back on the guide bar 11 and the guide roller 12, making smooth transport difficult. In addition, the perforation blade that forms the perforations in the long sheets may be damaged. From the viewpoint of ease of passage of the perforation blade when forming the perforations, a paper sheet connecting member 100 may be used. From the viewpoint of durability for long-term storage, the sheet connecting member 100 may be made of synthetic paper.

[0027] The sheet connecting member 100 includes a first piece 110, a second piece 130, a third piece 140, and a fourth piece 150. The sheet connecting member 100 has a substantially rectangular shape before being used to connect long sheets. The short side direction of the substantially rectangular shape of the sheet connecting member 100 (the left-right direction in FIG. 2 and the figures described below) is also referred to as the width direction of the sheet connecting member 100 in the description herein. The long side direction of the substantially rectangular shape of the sheet connecting member 100 (the up-down direction in FIG. 2 and the figures described below) is also referred to as the height direction of the sheet connecting member 100 in the description herein.

[0028] In the sheet connecting member 100, a center line 113 and partition lines 114, 115 are formed on the surface 101 of the first piece 110. The center line 113 is formed as a solid line extending in the height direction of the sheet connecting member 100. The partition lines 114, 115 are formed as dashed lines extending parallel to the height direction of the sheet connecting member 100. The center line 113 and the partition lines 114, 115 are printed on the surface 101 of the first piece 110, for example.

[0029] The center line 113 and the partition lines 114 and 115 are disposed at a distance from each other in the width direction of the sheet connecting member 100. The center line 113 is disposed at the center position of the sheet connecting member 100 in the width direction. The partition lines 114 and 115 are disposed on opposite sides of the center line 113. In the arrangement shown in Fig. 2, the partition line 114 is on the left side of the center line 113, and the partition line 115 is on the right side of the center line 113.

[0030] The distance between center line 113 and partition line 114 in the width direction of sheet connecting member 100 is equal to the distance between center line 113 and partition line 115 in the width direction of sheet connecting member 100. Partition line 114 and partition line 115 are arranged symmetrically with respect to center line 113 as the axis of symmetry.

[0031] The partition line 114 defines a first adhesive region 116 in which a first adhesive portion 111 (described later) is provided. The partition line 115 defines a second adhesive region 117 in which a second adhesive portion 112 (described later) is provided. A non-adhesive region 118 in which no adhesive portion is provided is formed between the partition lines 114 and 115 in the width direction of the sheet connecting member 100. The non-adhesive region 118 is divided by the center line 113 into an end arrangement region 119 and a start arrangement region 120. In the width direction of the sheet connecting member 100, the region between the partition line 114 and the center line 113 is the end arrangement region 119, and the region between the center line 113 and the partition line 115 is the start arrangement region 120.

[0032] The first piece 110 and the second piece 130 are formed integrally. The sheet connecting member 100 has a second piece boundary 122 that forms the boundary between the first piece 110 and the second piece 130. A fold line for folding is formed at the second piece boundary 122. A perforation is formed at the second piece boundary 122. The perforation may form the fold line, or the second piece boundary 122 may have a fold line formed by a press groove and further have a perforation formed therein.

[0033] Non-adhesive regions 118A and 118B where no adhesive portion is provided are formed on surface 101 of first piece 110 near second piece boundary 122. Non-adhesive region 118A is formed between first adhesive region 116 and second piece boundary 122 in the height direction of sheet connecting member 100. Non-adhesive region 118B is formed between second adhesive region 117 and second piece boundary 122 in the height direction of sheet connecting member 100.

[0034] A third adhesive region 136 in which a third adhesive portion 131 (described later) is provided, and a fourth adhesive region 137 in which a fourth adhesive portion 132 (described later) is provided are defined on the surface 101 of the second piece 130. The third adhesive region 136 and the fourth adhesive region 137 are spaced apart in the width direction of the sheet connecting member 100. A non-adhesive region 138 in which no adhesive portion is provided is formed between the third adhesive region 136 and the fourth adhesive region 137.

[0035] Non-adhesive regions 138A and 138B where no adhesive portion is provided are formed near the second piece boundary 122 on the surface 101 of the second piece 130. The non-adhesive region 138A is formed between the third adhesive region 136 and the second piece boundary 122 in the height direction of the sheet connecting member 100. The non-adhesive region 138B is formed between the fourth adhesive region 137 and the second piece boundary 122 in the height direction of the sheet connecting member 100.

[0036] In the width direction of the sheet connecting member 100, the first piece 110 and the second piece 130 have the same dimension. The peripheral edge of the first piece 110 and the peripheral edge of the second piece extending in the height direction of the sheet connecting member 100 extend on the same straight line. The dimension of the second piece 130 in the height direction of the sheet connecting member 100 is smaller than the dimension of the first piece 110 in the height direction of the sheet connecting member 100. The dimension of the first piece 110 in the height direction of the sheet connecting member 100 is smaller than the width dimension of the long sheets to be connected using the sheet connecting member 100.

[0037] The first piece 110 and the third piece 140 are formed integrally. The sheet connecting member 100 has a third piece boundary 123 that forms a boundary between the first piece 110 and the third piece 140. The third piece boundary 123 is shown by a two-dot chain line in FIG. 2. The third piece 140 is formed to protrude from the first piece 110 on the opposite side to the second piece 130 in the height direction of the sheet connecting member 100. In FIG. 2, the second piece 130 is disposed below the first piece 110, and the third piece 140 protrudes upward from the first piece 110.

[0038] A fifth adhesive region 147 in which a fifth adhesive portion 141 described below is provided is defined on the surface 101 of the third piece 140. The fifth adhesive region 147 is provided at the tip of the third piece 140 protruding from the first piece 110. The dimension of the first adhesive region 116 of the first piece 110 and the dimension of the third piece 140 in the width direction of the sheet connecting member 100 are made equal. The dimension of the first adhesive region 116 and the fifth adhesive region 147 in the width direction of the sheet connecting member 100 are made equal.

[0039] The third piece 140 has a third piece intermediate portion 148 between the fifth adhesive region 147 and the third piece boundary 123 in the height direction of the sheet connecting member 100. A third piece fold line 142 is formed in the third piece intermediate portion 148. A dashed dotted line extending in the width direction of the sheet connecting member 100 printed on the front surface 101 of the third piece 140 constitutes the third piece fold line 142. A press groove for folding may be formed along the third piece fold line 142. Instead of printing a line, the third piece fold line 142 may be a perforation extending in the width direction of the sheet connecting member 100.

[0040] A third piece perforation 143 extending in the width direction of the sheet connecting member 100 is formed in a portion of third piece intermediate portion 148 closer to third piece boundary 123. A third piece cutout portion 145 recessed from the periphery of third piece 140 is formed in a portion of third piece intermediate portion 148 closer to third piece boundary 123.

[0041] 3 is an enlarged view of the vicinity of third one cutout portion 145. Third one cutout portion 145 has a substantially triangular shape. The deepest part of third one cutout portion 145, which is recessed deepest from the periphery of third piece 140, is connected to third one perforation 143. Third one perforation 143 is formed by alternately arranging multiple long holes penetrating sheet connecting member 100 in the thickness direction and non-cut parts where no long holes are formed, in the width direction of sheet connecting member 100. The deepest part of third one cutout portion 145 is connected to the long hole of third one perforation 143.

[0042] Returning to Fig. 2, a third piece perforation 144 extending in the width direction of the sheet connecting member 100 is formed in a portion of the third piece intermediate portion 148 closer to the fifth adhesive region 147. A third piece cutout portion 146 recessed from the periphery of the third piece 140 is formed in a portion of the third piece intermediate portion 148 closer to the fifth adhesive region 147. The deepest portion of the third piece cutout portion 146 is connected to the long hole of the third piece perforation 144.

[0043] In the height direction of the sheet connecting member 100, the third one fold line 142 bisects the third one intermediate portion 148. The distance between the third one fold line 142 and the third one perforation 143 in the height direction of the sheet connecting member 100 is equal to the distance between the third one fold line 142 and the third one perforation 144 in the height direction of the sheet connecting member 100.

[0044] The first piece 110 and the fourth piece 150 are formed integrally. The sheet connecting member 100 has a fourth piece boundary 124 that forms a boundary between the first piece 110 and the fourth piece 150. The fourth piece boundary 124 is illustrated by a two-dot chain line in FIG. 2. The fourth piece 150 is formed to protrude from the first piece 110 on the opposite side to the second piece 130 in the height direction of the sheet connecting member 100. In FIG. 2, the second piece 130 is disposed below the first piece 110, and the fourth piece 150 protrudes upward from the first piece 110.

[0045] A sixth adhesive region 157 in which a sixth adhesive portion 151 described below is provided is defined on the surface 101 of the fourth piece 150. The sixth adhesive region 157 is provided at the tip of the fourth piece 150 protruding from the first piece 110. The dimension of the second adhesive region 117 of the first piece 110 and the dimension of the fourth piece 150 in the width direction of the sheet connecting member 100 are made equal. The dimension of the second adhesive region 117 and the sixth adhesive region 157 in the width direction of the sheet connecting member 100 are made equal.

[0046] The fourth piece 150 has a fourth piece intermediate portion 158 between the sixth adhesive region 157 and the fourth piece boundary 124 in the height direction of the sheet connecting member 100. A fourth piece fold line 152 is formed in the fourth piece intermediate portion 158. A dashed dotted line extending in the width direction of the sheet connecting member 100 printed on the front surface 101 of the fourth piece 150 constitutes the fourth piece fold line 152. A press groove for folding may be formed along the fourth piece fold line 152. Instead of printing a line, the fourth piece fold line 152 may be constituted by a perforation extending in the width direction of the sheet connecting member 100.

[0047] A fourth piece perforation 153 extending in the width direction of the sheet connecting member 100 is formed in a portion of fourth piece intermediate portion 158 closer to fourth piece boundary 124. A fourth piece cutout portion 155 recessed from the periphery of fourth piece 150 is formed in a portion of fourth piece intermediate portion 158 closer to fourth piece boundary 124. The deepest portion of fourth piece cutout portion 155 is connected to the long hole of fourth piece perforation 153.

[0048] A fourth piece perforation 154 extending in the width direction of the sheet connecting member 100 is formed in a portion of the fourth piece intermediate portion 158 closer to the sixth adhesive region 157. A fourth piece cutout portion 156 recessed from the periphery of the fourth piece 150 is formed in a portion of the fourth piece intermediate portion 158 closer to the sixth adhesive region 157. The deepest portion of the fourth piece cutout portion 156 is connected to the long hole of the fourth piece perforation 154.

[0049] In the height direction of the sheet connecting member 100, the fourth one fold line 152 bisects the fourth one intermediate portion 158. The distance between the fourth one fold line 152 and the fourth one perforation 153 in the height direction of the sheet connecting member 100 is equal to the distance between the fourth one fold line 152 and the fourth one perforation 154 in the height direction of the sheet connecting member 100.

[0050] In each perforation formed in the sheet connecting member 100, the length of the slot in the width direction of the sheet connecting member 100 may be equal to the length of the non-cut portion in the width direction of the sheet connecting member 100. The length of the slot may be different from the length of the non-cut portion. For example, the length of the slot may be twice the length of the non-cut portion.

[0051] Fig. 4 is a front view showing a schematic configuration of a sheet connecting member 100 on which an adhesive portion is formed. In Fig. 4 and the subsequent figures, the adhesive portion is illustrated by dot hatching.

[0052] In the first adhesive region 116 shown in FIG. 2, an adhesive layer having adhesive properties is formed, and a first adhesive portion 111 is formed.

In the sixth adhesive region 157, an adhesive layer having adhesive properties is formed, and a sixth adhesive portion 151 is formed.

[0053] The adhesive layer may be formed by applying an adhesive to each adhesive region. A removable adhesive that can be repeatedly applied and removed may be used, in which case the long sheet can be reapplied after being adhered. For example, Rt-BN, Rt-H, SP-H, and Rnon manufactured by Maruu Adhesive Co., Ltd. may be used. An adhesive that is not removable may be used. For example, AS-7715 manufactured by Lion Specialty Chemicals Co., Ltd. may be used. Alternatively, the adhesive layer may be formed by attaching an adhesive sheet to each adhesive region.

[0054] The first adhesive portion 111 and the second adhesive portion 112 are arranged at an interval in the width direction of the sheet connecting member 100. A non-adhesive region 118 is interposed between the first adhesive portion 111 and the second adhesive portion 112. The third adhesive portion 131 and the fourth adhesive portion 132 are arranged at an interval in the width direction of the sheet connecting member 100. A non-adhesive region 138 is interposed between the third adhesive portion 131 and the fourth adhesive portion 132.

[0055] The first adhesive portion 111 and the third adhesive portion 131 have the same dimension in the width direction of the sheet connecting member 100. The second adhesive portion 112 and the fourth adhesive portion 132 have the same dimension in the width direction of the sheet connecting member 100. The non-adhesive region 118 and the non-adhesive region 138 have the same dimension in the width direction of the sheet connecting member 100.

[0057] The third adhesive portion 131 is disposed at a distance from the second piece boundary 122 in the height direction of the sheet connecting member 100. A non-adhesive region 138A is interposed between the third adhesive portion 131 and the second piece boundary 122. The fourth adhesive portion 132 is disposed at a distance from the second piece boundary 122 in the height direction of the sheet connecting member 100. A non-adhesive region 138B is interposed between the fourth adhesive portion 132 and the second piece boundary 122.

[0058] The fifth adhesive portion 141 is disposed at a distance from the third piece boundary 123 in the height direction of the sheet connecting member 100. The dimension of the first adhesive portion 111 and the dimension of the fifth adhesive portion 141 in the width direction of the sheet connecting member 100 are equal. Between the fifth adhesive portion 141 and the third piece boundary 123, a third piece intermediate portion 148 where no adhesive portion is provided is interposed.

[0059] The sixth adhesive portion 151 is disposed at a distance from the fourth piece boundary 124 in the height direction of the sheet connecting member 100. The dimension of the second adhesive portion 112 and the dimension of the sixth adhesive portion 151 in the width direction of the sheet connecting member 100 are equal. Between the sixth adhesive portion 151 and the fourth piece boundary 124, a fourth piece intermediate portion 158 where no adhesive portion is provided is interposed.

[0060] Fig. 5 is a front view showing a first example of the release paper. The release paper is made of, for example, paper having a surface that has been subjected to a release treatment, such as a resin coating, to facilitate release from each adhesive portion. The release paper 161 shown in Fig. 5 covers the entire sheet connecting member 100. The release paper 161 covers the first adhesive portion 111 and the second adhesive portion 112 shown in Fig. 4. The release paper 161 further covers the third adhesive portion 131 and the fourth adhesive portion 132. The release paper 161 further covers the fifth adhesive portion 141. The release paper 161 further covers the sixth adhesive portion 151.

[0061] 6 is a front view showing a second example of the release paper. FIG. 6 shows a release paper 161 covering the upper part of the sheet connecting member 100 in the height direction, and a second release paper 162 covering the lower part of the sheet connecting member 100 in the height direction. The release paper 161 covers the range from the second piece boundary 122 to the upper end of the sheet connecting member 100 (i.e., the tips of the third piece 140 and the fourth piece 150) in the height direction of the sheet connecting member 100. The release paper 161 covers the first piece 110, the third piece 140, and the fourth piece 150. The release paper 161 covers the first adhesive portion 111 and the second adhesive portion 112 shown in FIG. 4. The release paper 161 further covers the fifth adhesive portion 141. The release paper 161 further covers the sixth adhesive portion 151.

[0062] The second release paper 162 is configured as a separate body from the release paper 161. The release paper 161 and the second release paper 162 are not connected, and a gap is provided between the release paper 161 and the second release paper 162. The second release paper 162 covers an area extending from the second piece boundary 122 to the lower end of the sheet connecting member 100 in the height direction of the sheet connecting member 100. The second release paper 162 covers the second piece 130. The second release paper 162 covers the third adhesive portion 131 and the fourth adhesive portion 132.

[0063] The dimension of the second release paper 162 in the height direction of the sheet connecting member 100 may be smaller than the dimension of the second piece 130. In this case, the release paper 161 may be formed so as to extend beyond the second piece boundary 122 and cover a portion of the second piece 130.

[0064] <Procedure for connecting long sheets> The procedure for connecting long sheets using the sheet connecting member 100 having the above-described configuration will be described below. As described below, the circled Arabic numerals printed on the surface 101 of the sheet connecting member 100 indicate the order in which the long sheets are adhered to the adhesive portions of the sheet connecting member 100.

[0065] 7 is a schematic diagram showing a first step of connecting long sheets. First, the release paper 161 covering the first piece 110, the third piece 140, and the fourth piece 150 is peeled off. By peeling off the release paper 161, the first adhesive portion 111, the second adhesive portion 112, the fifth adhesive portion 141, and the sixth adhesive portion 151 are exposed.

[0066] 5 is used, the entire release paper 161 may be peeled off, or the release paper 161 may be folded at the position of the second piece boundary 122 so that the release paper 161 remains covering the second piece 130. When the combination of the release paper 161 and the second release paper 162 shown in FIG. 6 is used, the entire release paper 161 is peeled off, while the second release paper 162 is left unpeeled so that the second release paper 162 remains covering the second piece 130.

[0067] 7, a first long sheet, for example, the end portion of a used packaging sheet P1, is attached to the first adhesive portion 111. At this time, the attachment is performed so that the end portion P1E of the used packaging sheet P1 is disposed in the end portion arrangement region 119. In addition, the attachment is performed so that the open end Pa of the used packaging sheet P1 is disposed to face the third piece 140.

[0068] 8 is a schematic diagram showing a second procedure for connecting long sheets. As shown in FIG. 8, the third piece 140 is folded along the third piece fold line 142. The fifth adhesive portion 141 provided at the tip of the third piece 140 overlaps the used packaging sheet P1, and the fifth adhesive portion 141 adheres to the end of the used packaging sheet P1. At this time, the fifth adhesive portion 141 is adhered to the surface (the surface on the near side of the paper in FIG. 8) of the end of the used packaging sheet P1 opposite to the surface to which the first adhesive portion 111 is adhered (the surface on the far side of the paper in FIG. 8). The fifth adhesive portion 141 is adhered to a portion of the used packaging sheet P1 near the open end Pa.

[0069] When third piece 140 is folded along third piece fold line 142, third piece perforation 143 and third piece perforation 144 overlap each other. When third piece 140 is folded along third piece fold line 142, third piece cutout portion 145 and third piece cutout portion 146 overlap each other.

[0070] 9 is a schematic diagram showing a third procedure for connecting long sheets. As shown in FIG. 9, a second long sheet, for example, a start end of an unused packaging sheet P2, is attached to the second adhesive portion 112. At this time, the attachment is performed so that the start end P2E of the unused packaging sheet P2 is disposed in the start end arrangement region 120. In the width direction of the sheet connecting member 100, the end end P1E of the used packaging sheet P1 and the start end P2E of the unused packaging sheet P2 are disposed with a gap therebetween. In addition, the attachment is performed so that the open end Pa of the unused packaging sheet P2 is disposed to face the fourth piece 150.

[0071] Fig. 10 is a schematic diagram showing a fourth procedure for connecting long sheets. As shown in Fig. 10, the fourth piece 150 is folded along the fourth piece fold line 152. The sixth adhesive portion 151 provided at the tip of the fourth piece 150 overlaps the unused packaging sheet P2, and the sixth adhesive portion 151 is adhered to the starting end of the unused packaging sheet P2. At this time, the sixth adhesive portion 151 is adhered to the surface (the surface on the front side of the paper in Fig. 10) of the starting end of the unused packaging sheet P2 opposite to the surface to which the second adhesive portion 112 is adhered (the surface on the back side of the paper in Fig. 10). The sixth adhesive portion 151 is adhered to a portion of the unused packaging sheet P2 near the open end Pa.

[0072] When fourth piece 150 is folded along fourth piece fold line 152, fourth piece perforation 153 and fourth piece perforation 154 overlap each other. When fourth piece 150 is folded along fourth piece fold line 152, fourth piece cutout portion 155 and fourth piece cutout portion 156 overlap each other.

[0073] Fig. 11 is a schematic diagram showing a fifth procedure for connecting long sheets. The release paper 161 shown in Fig. 5 or the second release paper 162 shown in Fig. 6 is peeled off to expose the third adhesive portion 131 and the fourth adhesive portion 132. As shown in Fig. 11, the second piece 130 is folded along the second piece boundary 122. The third adhesive portion 131 provided on the second piece 130 overlaps the used packaging sheet P1, and the third adhesive portion 131 is adhered to the end portion of the used packaging sheet P1. At this time, the third adhesive portion 131 is adhered to the surface (the surface on the front side of the paper in Fig. 11) opposite to the surface to which the first adhesive portion 111 is adhered (the surface on the rear side of the paper in Fig. 11).

[0074] Further, the fourth adhesive portion 132 provided on the second piece 130 overlaps the unused packaging sheet P2, and the fourth adhesive portion 132 adheres to the starting end of the unused packaging sheet P2. At this time, the fourth adhesive portion 132 adheres to the surface (the surface on the front side of the paper in FIG. 11) of the starting end of the unused packaging sheet P2 opposite to the surface to which the second adhesive portion 112 is adhered (the surface on the rear side of the paper in FIG. 11).

[0075] A portion of the folded second piece 130 overlaps a portion of the previously folded third piece 140, and overlaps a portion of the fourth piece 150. As described above, since the dimension of the second piece 130 is smaller than that of the first piece 110 in the height direction of the sheet connecting member 100, the edge of the folded second piece 130 does not overlap the third piece boundary 123 and the fourth piece boundary 124. Therefore, the second piece 130 does not overlap the third piece perforations 143, 144 formed in the third piece intermediate portion 148. The second piece 130 does not overlap the fourth piece perforations 153, 154 formed in the fourth piece intermediate portion 158.

[0076] 12 is a schematic diagram showing a sixth procedure for connecting long sheets. An operator holds third piece intermediate portion 148 by hand and cuts third piece perforations 143, 144. This separates third piece intermediate portion 148 from first piece 110 and from fifth adhesive portion 141. An operator also holds fourth piece intermediate portion 158 by hand and cuts fourth piece perforations 153, 154. This separates fourth piece intermediate portion 158 from first piece 110 and from sixth adhesive portion 151.

[0077] Through the above steps, the used packaging sheet P1 and the unused packaging sheet P2 connected via the sheet connecting member 100 are wound around the guide roller 12 shown in FIG. 1. At this time, the roll body Q of the unused packaging sheet P2 is attached to the medicine packaging device A. In this state, the sheet conveying device 4 is driven to convey the used packaging sheet P1 and the unused packaging sheet P2 along the conveying direction X. The unused packaging sheet P2 is conveyed until the sheet connecting member 100 passes through the feed rollers 41 and the pair of feed rollers 41 sandwich the unused packaging sheet P2. By eliminating the need for manual loading, the unused packaging sheet P2 can be easily and safely loaded into the medicine packaging device A.

[0078] The above-described procedure for connecting the used packaging sheet P1 and the unused packaging sheet P2 and the procedure for loading the unused packaging sheet P2 may be configured so that an operator can confirm them by looking at the sheet connecting member 100. In this way, even an operator who is unfamiliar with the task of replacing the packaging sheet P can perform the tasks of connecting and loading the packaging sheets in the correct order.

[0079] For example, instructions on the procedure for connecting the used packaging sheet P1 to the unused packaging sheet P2 and the procedure for loading the used packaging sheet P2 may be printed on the front surface 101 of the second piece 130. Instructions on the procedure for connecting the used packaging sheet P1 to the unused packaging sheet P2 and the procedure for loading the used packaging sheet P2 may be printed on the back surfaces of the first piece 110 and the second piece 130, in which case a notice urging the operator to check the procedure printed on the back surface may be printed on the front surface 101 of the second piece 130. A separate piece of paper on which instructions on the procedure for connecting the used packaging sheet P1 to the unused packaging sheet P2 and the procedure for loading the used packaging sheet P2 are printed may be formed integrally with the first piece 110 via a perforation.

[0080] Alternatively, a matrix-type two-dimensional code in which information is displayed in a vertical and horizontal mosaic pattern of white and black cells may be printed on surface 101 of second piece 130. By reading the two-dimensional code with a terminal, the worker may be able to access a website that displays a procedure for connecting used packaging sheet P1 and unused packaging sheet P2, and a procedure for loading unused packaging sheet P2.

[0081] <Action and Effects> Although some of the description herein overlaps with the above description, the characteristic configuration and effects of this embodiment can be summarized as follows.

[0082] As shown in FIG. 4, the sheet connecting member 100 has a sheet-like shape having a front surface 101 and a back surface opposite to the front surface 101. The front surface 101 has a first adhesive portion 111 and a second adhesive portion 112. As shown in FIG. 7, the end portion of the used packaging sheet P1 is adhered to the first adhesive portion 111. As shown in FIG. 9, the start end portion of the used packaging sheet P2 is adhered to the second adhesive portion 112. By using the sheet connecting member 100 to adhere the end portion of the used packaging sheet P1 to the first adhesive portion 111 and the start end portion of the used packaging sheet P2 to the second adhesive portion 112, the end portion of the used packaging sheet P1 and the start end of the used packaging sheet P2 can be easily connected.

[0083] As shown in Fig. 4, the first adhesive portion 111 and the second adhesive portion 112 may be disposed with a gap therebetween. If there is no gap between the first adhesive portion 111 and the second adhesive portion 112, the end portion of the used packaging sheet P1 and the beginning portion of the unused packaging sheet P2, both of which are adhered to the sheet connecting member 100, may overlap each other. In this case, the open end Pa of the unused packaging sheet P2 may not open when passing through the triangular plate 14 (Fig. 1). Alternatively, the first adhesive portion 111 and / or the second adhesive portion 112 of the first piece 110 may be firmly adhered to the third adhesive portion 131 and / or the fourth adhesive portion 132 of the second piece 130, and the folded sheet connecting member 100 may not open, and the sheet connecting member 100 may not pass through the triangular plate 14.

[0084] 9, the first adhesive portion 111 and the second adhesive portion 112 are arranged with a gap therebetween, so that both the end P1E and the start P2E can be arranged in the non-adhesive region 118 between the first adhesive portion 111 and the second adhesive portion 112. This allows the open end Pa of the unused packaging sheet P2 to be reliably opened when passing through the triangular plate 14, so that the unused packaging sheet P2 can be easily loaded into the drug packaging device A.

[0085] 9 shows an example in which the end P1E of the used packaging sheet P1 and the start P2E of the unused packaging sheet P2 are spaced apart, the end P1E and the start P2E do not necessarily have to be spaced apart as long as the end portion of the used packaging sheet P1 and the start portion of the unused packaging sheet P2 do not overlap each other. In other words, the distance between the end P1E and the start P2E in the width direction of the sheet connecting member 100 may be zero.

[0086] 5 and 6, the sheet connecting member 100 may further include a release paper 161 that covers the first adhesive portion 111 and the second adhesive portion 112. Both the first adhesive portion 111 and the second adhesive portion 112 can be exposed by a single operation of peeling off one sheet of release paper 161, thereby improving workability.

[0087] As shown in Figs. 2 and 4, the sheet connecting member 100 may include an integral first piece 110 and a second piece 130. The surface 101 of the first piece 110 may have a first adhesive portion 111 and a second adhesive portion 112. The surface 101 of the second piece 130 may have a third adhesive portion 131 and a fourth adhesive portion 132. As shown in Figs. 9 to 11, the third adhesive portion 131 may be adhered to a surface of a trailing end of the packaging sheet P1 after use, opposite to a surface to which the first adhesive portion 111 is adhered. The fourth adhesive portion 132 may be adhered to a surface of a starting end of the packaging sheet P2 before use, opposite to a surface to which the second adhesive portion 112 is adhered.

[0088] By adhering the first adhesive portion 111 to one surface of the end portion of the used packaging sheet P1 and the third adhesive portion 131 to the other surface, and by adhering the second adhesive portion 112 to one surface of the start portion of the unused packaging sheet P2 and the fourth adhesive portion 132 to the other surface, the strength of the connection between the used packaging sheet P1 and the unused packaging sheet P2 can be improved. Also, it is possible to reliably prevent the open end Pa of the packaging sheet P from spreading out at an unintended position when being transported through the drug packaging device A and getting caught in the device by protruding from the path.

[0089] 4, the third adhesive portion 131 and the fourth adhesive portion 132 may be disposed with a gap therebetween. This allows both the end P1E and the beginning P2E to be disposed in the non-adhesive region 138 between the third adhesive portion 131 and the fourth adhesive portion 132. Since the open end Pa of the unused packaging sheet P2 can be reliably opened when passing through the triangular plate 14, the unused packaging sheet P2 can be easily loaded into the drug packaging device A.

[0090] 5, the release paper 161 may further cover the third adhesive portion 131 and the fourth adhesive portion 132. By peeling off one piece of release paper 161 in a single operation, the third adhesive portion 131 and the fourth adhesive portion 132 can be exposed in addition to the first adhesive portion 111 and the second adhesive portion 112, thereby improving workability.

[0091] 6, the sheet connecting member 100 may further include a second release paper 162 that is separate from the release paper 161 and covers the third adhesive portion 131 and the fourth adhesive portion 132. This can prevent the packaging sheet P from accidentally sticking to the third adhesive portion 131 or the fourth adhesive portion 132 during the operation of adhering the packaging sheet P to the first adhesive portion 111 and the second adhesive portion 112. This can prevent the packaging sheet P from sticking to the sheet connecting member 100 in a position that is different from the appropriate position or in an unintended position, and the packaging sheet P can be adhered to the sheet connecting member 100 in an appropriate position.

[0092] 2 and 4, a fold line may be formed at second piece boundary 122 that forms the boundary between first piece 110 and second piece 130. A worker can easily fold second piece 130 relative to first piece 110 along the fold line.

[0093] 2 and 4, a perforation may be formed at a second piece boundary 122 that forms a boundary between the first piece 110 and the second piece 130. By forming a perforation at the second piece boundary 122, the first piece 110 and the second piece 130 can be easily separated at the second piece boundary 122. When a torsional load acts on the sheet connecting member 100 while a used packaging sheet P1 and an unused packaging sheet P2 connected by the sheet connecting member 100 are being transported through the drug packaging device A, the first piece 110 and the second piece 130 separate, thereby absorbing the torsional load.

[0094] 4, the first adhesive portion 111 may be disposed at a distance from the second piece boundary 122. The second adhesive portion 112 may be disposed at a distance from the second piece boundary 122. The end portion of the used packaging sheet P1 can be provisionally placed in the non-adhesive region 118A between the first adhesive portion 111 and the second piece boundary 122 to position the used packaging sheet P1 relative to the sheet connecting member 100, and then the used packaging sheet P1 can be adhered to the first adhesive portion 111. The start portion of the unused packaging sheet P2 can be provisionally placed in the non-adhesive region 118B between the second adhesive portion 112 and the second piece boundary 122 to position the used packaging sheet P2 relative to the sheet connecting member 100, and then the used packaging sheet P2 can be adhered to the second adhesive portion 112. This makes it possible to prevent the packaging sheet P from adhering to the sheet connecting member 100 in an inclined position, and allows the packaging sheet P to be adhered to the sheet connecting member 100 in an appropriate position.

[0095] 2 and 4, the sheet connecting member 100 may further include a third piece 140 that is formed integrally with the first piece 110 and protrudes from the first piece 110 on a side opposite to the second piece 130. The surface 101 of the third piece 140 may have a fifth adhesive portion 141. As shown in FIGS. 7 and 8, the fifth adhesive portion 141 may be adhered to a surface of the end portion of the packaging sheet P1 after use, opposite to the surface to which the first adhesive portion 111 is adhered.

[0096] By folding the third piece 140 and adhering the fifth adhesive portion 141 to the used packaging sheet P1, the surface of the end portion of the used packaging sheet P1 opposite the surface to which the first adhesive portion 111 is adhered can be temporarily held down by the third piece 140. This makes it possible to prevent the surface of the end portion of the used packaging sheet P1 opposite the surface to which the first adhesive portion 111 is adhered from curling when the second piece 130 is folded along the second piece boundary 122.

[0097] 4, fifth adhesive portion 141 is disposed at a distance from third piece boundary 123 that forms the boundary between first piece 110 and third piece 140, and third piece 140 further has third piece intermediate portion 148 between third piece boundary 123 and fifth adhesive portion 141, and third piece fold line 142 may be formed in third piece intermediate portion 148. An operator can easily perform the operation of folding third piece 140 relative to first piece 110 along third piece fold line 142.

[0098] 2 and 4, third piece intermediate portion 148 may have third piece perforations 143, 144 formed therein. An operator can easily separate third piece intermediate portion 148 from first piece 110 by cutting off third piece perforation 143, and can easily separate third piece intermediate portion 148 from fifth adhesive portion 141 by cutting off third piece perforation 144.

[0099] 2 and 4, third piece intermediate portion 148 may have third piece cutout portions 145, 146 recessed from the periphery of third piece 140. As shown in Fig. 3, the deepest portion of third piece cutout portion 145 may be connected to third piece perforation 143, and the deepest portion of third piece cutout portion 146 may be connected to third piece perforation 144. This makes it easier to cut out third piece perforations 143, 144.

[0100] 12, the third piece intermediate portion 148 may be formed to be separable from the first piece 110 and also separable from the fifth adhesive portion 141. After folding the third piece 140 and adhering the fifth adhesive portion 141 to the packaging sheet P, the third piece intermediate portion 148 is separated from the first piece 110 and the fifth adhesive portion 141, thereby reducing the dimension by which the sheet connecting member 100 protrudes from the packaging sheet P. Typically, the sheet connecting member 100 can be prevented from protruding from the packaging sheet P. When the sheet connecting member 100 is transported through the drug packaging device A, it is possible to reliably prevent the portion protruding from the packaging sheet P from getting caught in the device.

[0101] 5 and 6, the release paper 161 may further cover the fifth adhesive portion 141. By a single operation of peeling off one sheet of release paper 161, the fifth adhesive portion 141 can be exposed in addition to the first adhesive portion 111 and the second adhesive portion 112, thereby improving workability.

[0102] 2 and 4, the sheet connecting member 100 may further include a fourth piece 150 that is formed integrally with the first piece 110 and protrudes from the first piece 110 on a side opposite to the second piece 130. The surface 101 of the fourth piece 150 may have a sixth adhesive portion 151. As shown in FIGS. 9 and 10, the sixth adhesive portion 151 may be adhered to a surface of the starting end of the packaging sheet P2 before use, opposite to the surface to which the second adhesive portion 112 is adhered.

[0103] By folding the fourth piece 150 and adhering the sixth adhesive portion 151 to the unused packaging sheet P2, the surface of the starting end of the unused packaging sheet P2 opposite to the surface to which the second adhesive portion 112 is adhered can be temporarily held down by the fourth piece 150. This makes it possible to prevent the surface of the starting end of the unused packaging sheet P2 opposite to the surface to which the second adhesive portion 112 is adhered from curling when the second piece 130 is folded along the second piece boundary 122.

[0104] 4, sixth adhesive portion 151 is disposed at a distance from fourth piece boundary 124 that forms the boundary between first piece 110 and fourth piece 150, and fourth piece 150 further has fourth piece intermediate portion 158 between fourth piece boundary 124 and sixth adhesive portion 151, and fourth piece fold line 152 may be formed in fourth piece intermediate portion 158. A worker can easily perform the task of folding fourth piece 150 relative to first piece 110 along fourth piece fold line 152.

[0105] 2 and 4, fourth piece intermediate portion 158 may have fourth piece perforations 153, 154 formed therein. An operator can easily separate fourth piece intermediate portion 158 from first piece 110 by cutting off fourth piece perforation 153, and can easily separate fourth piece intermediate portion 158 from sixth adhesive portion 151 by cutting off fourth piece perforation 154.

[0106] 2 and 4, fourth piece intermediate portion 158 may have fourth piece cutout portions 155, 156 recessed from the periphery of fourth piece 150. The deepest portion of fourth piece cutout portion 155 may be connected to fourth piece perforation 153, and the deepest portion of fourth piece cutout portion 156 may be connected to fourth piece perforation 154. This makes it easier to cut out fourth piece perforations 153, 154.

[0107] 12, the fourth piece intermediate portion 158 may be formed to be separable from the first piece 110 and also separable from the sixth adhesive portion 151. After the fourth piece 150 is folded and the sixth adhesive portion 151 is adhered to the packaging sheet P, the fourth piece intermediate portion 158 is separated from the first piece 110 and from the sixth adhesive portion 151, thereby reducing the dimension by which the sheet connecting member 100 protrudes from the packaging sheet P. Typically, the sheet connecting member 100 can be prevented from protruding from the packaging sheet P. When the sheet connecting member 100 is transported through the drug packaging device A, it is possible to reliably prevent the portion protruding from the packaging sheet P from getting caught in the device.

[0108] 5 and 6, the release paper 161 may further cover the sixth adhesive portion 151. By a single operation of peeling off one sheet of release paper 161, the sixth adhesive portion 151 can be exposed in addition to the first adhesive portion 111 and the second adhesive portion 112, thereby improving workability.

[0109] [Second embodiment] Fig. 13 is a front view showing a schematic configuration of a sheet connecting member 100 of the second embodiment. The sheet connecting member 100 of the second embodiment shown in Fig. 13 differs from the first embodiment in the configurations of a third piece 140 and a fourth piece 150.

[0110] In the third piece 140 of the second embodiment, a third piece perforation 143 extending in the width direction of the sheet connecting member 100 is formed in a third piece intermediate portion 148. A third piece cutout portion 145 recessed from the periphery of the third piece 140 is formed in the third piece intermediate portion 148. In the height direction of the sheet connecting member 100, the third piece perforation 143 divides the third piece intermediate portion 148 in half. The distance between the third piece boundary 123 and the third piece perforation 143 in the height direction of the sheet connecting member 100 is equal to the distance between the third piece perforation 143 and the fifth adhesive portion 141 in the height direction of the sheet connecting member 100.

[0111] One third piece perforation 143 is formed in third piece intermediate portion 148, and third piece perforation 144 shown in Fig. 4 is not formed in third piece intermediate portion 148 of the second embodiment. Third piece fold line 142 shown in Fig. 4 is not formed in third piece intermediate portion 148 of the second embodiment.

[0112] In the fourth piece 150 of the second embodiment, a fourth piece perforation 153 extending in the width direction of the sheet connecting member 100 is formed in a fourth piece intermediate portion 158.
