Then, the plurality of second narrow belts 167 travel in a closed curve between the second pulley 162 and the third pulley 164 , and the third by friction with the plurality of second narrow belts 167 . The pulley 164 rotates.

The first guide 168 is disposed between the front frame 151 and the rear frame 153 so as not to interfere with the plurality of first narrow belts 166 and the plurality of second narrow belts 167 . The first guide 168 is a smooth curved path when the drug wrapping paper 4 proceeds along the driving direction of the plurality of second narrow belts 167 and switches to the driving direction of the plurality of first narrow belts 166. It is extended diagonally to proceed along. The second guide 169 is disposed between the front frame 151 and the rear frame 153 so as not to interfere with the plurality of first narrow belts 166 . The second guide 169 extends upwardly inclined at the end so that the drug wrapping paper 4 proceeds along the traveling direction of the plurality of first narrow belts 166 and then smoothly passes to the belt conveyor 200 .

With this configuration, when the motor shaft of the electric motor 156 rotates, the drug wrapping paper 4 that advances down from the upper side of the third pulley 164 and enters the transfer unit 150 is a plurality of second narrow belts. The third pulley 164 proceeds in the direction from the third pulley 164 to the second pulley 162 by friction with the 167, and the moving direction is switched to form a smooth curve by the first guide 168, and a plurality of first narrow widths The first pulley 162 proceeds in the direction toward the first pulley 160 by friction with the belt 166 , and the belt conveyor 200 smoothly rides by the second guide 169 .

The tension roller 170 is a roller in contact with the drug wrapping paper 4 that proceeds by the transfer unit 150, and the position is changed according to the magnitude of the tension of the drug wrapping paper 4 . The tension roller 170 includes a roller shaft 171 parallel to the Y-axis, and a roller body 172 that surrounds the roller shaft 171 and is joined to the roller shaft 171 . The roller body 172 is formed of, for example, an elastic foamed resin material such as a sponge.

The tension roller 170 is pivotable about the rotation axis PS parallel to the Y axis by the front end support bracket 173 and the rear end support bracket 189 so that the front frame 151 and the rear frame 153 are pivotable. ) is supported. Specifically, one end of the front end support bracket 173 is supported by the front end of the rotation shaft (not shown) crossing the front frame 151 and the rear frame 153 along the rotation axis PS, and the front end support bracket ( The other end of the 173) supports the front end of the roller shaft 171, so that the front end support bracket 173 is rotatable about the rotation axis PS. One end of the rear end support bracket 189 is supported by the rear end of the rotation shaft, and the other end of the rear end support bracket 189 supports the rear end of the roller shaft 171, so that the rear end support bracket 189 is rotated. It is rotatable about the axis line PS.

The tension roller 170 maintains contact with the drug wrapping paper 4 introduced into the transport unit 150 from the upper side of the third pulley 164 by its own weight, and the size of the tension of the drug wrapping paper 4 increases increases as the In other words, as the progressing speed of the drug wrapping paper 4 progressed by the transfer unit 150 increases, the tension of the drug wrapping paper 4 increases and the curved progress path of the drug wrapping paper 4 in the transfer unit 150 is shorter. While being changed so as to be changed, the tension roller 170 is pushed by the drug wrapping paper 4 and is lifted while rotating about the rotation axis PS.

The tension roller 170 rotates in a direction to help the progress of the drug wrapping paper 4 in contact with the outer peripheral surface of the roller body 172 by the power of the electric motor 156. Specifically, as a means for rotationally driving the tension roller 170, the drug wrapping paper discharging device 100 is a second pulley coaxial gear 190, a connecting gear 191, a connecting gear coaxial pulley 192, an intermediate pulley 193 ), a tension roller coaxial pulley 186 , a third narrow belt 187 , and a fourth narrow belt 188 . The second pulley coaxial gear 190 is disposed in front of the front frame 151 and is coaxially connected to the second pulley 162 to rotate together with the second pulley 162 . The connecting gear 191 is disposed in front of the front frame 151 and is meshed with the second pulley coaxial gear 190 . The connecting gear coaxial pulley 192 is a pulley coaxially fixed to the second pulley coaxial gear 190 .

The intermediate pulley 193 is disposed in front of the front frame 151 and is coaxially connected to a rotation shaft (not shown) extending along the rotation axis PS. The tension roller coaxial pulley 186 is coaxially coupled to the roller shaft 171 . The third narrow belt 187 has the connecting gear coaxial pulley 192 and the intermediate pulley 193 so that when the connecting gear coaxial pulley 192 rotates, the rotational force is transmitted to the intermediate pulley 193 so that the intermediate pulley 193 rotates. ) and connect it. In other words, when the connecting gear coaxial pulley 192 rotates, the third narrow belt 187 travels in a closed curve between the connecting gear coaxial pulley 192 and the intermediate pulley 193, and the third narrow belt The intermediate pulley 193 rotates by friction with the 187 .

In the fourth narrow belt 188, when the intermediate pulley 193 rotates, the rotational force is transmitted to the tension roller coaxial pulley 186 so that the tension roller coaxial pulley 186 and the roller shaft 171 fixedly coupled thereto rotate. The intermediate pulley 193 and the tension roller coaxial pulley 186 are wound and connected. In other words, when the intermediate pulley 193 rotates, the fourth narrow belt 188 travels in a closed curve between the intermediate pulley 193 and the tension roller coaxial pulley 186, and the fourth narrow belt 188 ) and the tension roller coaxial pulley 186 and the tension roller 170 coaxially coupled thereto rotate by friction. The third narrow belt 187 and the fourth narrow belt 188 are also similar to the first narrow belt 166 and the second narrow belt 167, and the cross-sectional shape thereof may be a square or a circular shape having substantially the same width and thickness, and , for example, may be made of a rubber material such as urethane rubber.

The first and second tension roller detection sensors 180 and 183 are sensors for detecting the position of the tension roller 170 and are disposed to be spaced apart from each other. The first and second tension roller detection sensors 180 and 183 are fixedly supported by the first and second sensor brackets 177 and 178 fixedly supported on the front frame 151 . The second tension roller detection sensor 183 is located at about the same height as the rotation axis PS, and the first tension roller detection sensor 180 is located below the second tension roller detection sensor 183 .

The first and second tension roller detection sensors 180 and 183 are photo sensors, and each of the light emitting units 181 and 184 for projecting light includes the light emitting units 181 and 184. ) and light receiving units 182 and 185 for receiving the projected light and generating a detection signal. A sensor dog 174 extending downwardly forming an angle of approximately 90° with the front support bracket 173 is fixedly coupled to one end of the front support bracket 173 . Accordingly, when the tension roller 170 moves up and down while rotating around the rotation axis PS, the sensor dock 174 also moves the tension roller 170 and the shear support bracket 173 around the rotation axis PS. ) and rotates at the same angle.

5 to 7 is a front view showing a change in the position of the tension control roller according to the tension of the drug wrapping paper in the drug wrapping paper discharging device of the present invention. 2 to 7 , the sensor dock 174 includes a lower end 175 that may be interposed between the light emitting unit 181 and the light receiving unit 182 of the first tension roller detection sensor 180 , and An upper protrusion 176 that may be interposed between the light emitting unit 184 and the light receiving unit 185 of the second tension roller detection sensor 183 is provided.

In other words, as shown in FIG. 5, the tension roller 170 is in contact with the first guide 168 and the second guide 169 with the drug wrapping paper 4 interposed therebetween, or the first guide 168 and When positioned at a low height close to the second guide 169 , the lower end 175 is interposed between the light emitting unit 181 and the light receiving unit 182 of the first tension roller detection sensor 180 . In this case, since the light projected from the light emitting unit 181 does not reach the light receiving unit 182 , the detection signal of the first tension roller detection sensor 180 is not generated.

However, as shown in FIG. 6 or FIG. 7 , when the tension roller 170 rises higher than the position of FIG. 5 because the tension size of the drug wrapping paper 4 increases, the lower end 175 is the first tension roller detection sensor 180 ) does not overlap the light emitting unit 181 and the light receiving unit 182 in a direction parallel to the Y axis. In this case, the light projected from the light emitting unit 181 is received by the light receiving unit 182 to generate a detection signal of the first tension roller detection sensor 180 .

On the other hand, when the tension roller 170 is lifted by the drug wrapping paper 14 to such an extent that the upper end of the tension roller 170 is positioned higher than the third pulley 164 as shown in FIG. 7, the lower end 175 not only does not overlap the light emitting part 181 and the light receiving part 182 of the first tension roller detection sensor 180 in a direction parallel to the Y axis, but also the upper protrusion 176 of the second tension roller detection sensor 183 ) does not overlap the light emitting unit 184 and the light receiving unit 185 in a direction parallel to the Y axis. In this case, the light projected from the light emitting unit 184 of the second tension roller detection sensor 183 is received by the light receiving unit 185 of the second tension roller detection sensor 183 and the second tension roller detection sensor 183 . A detection signal is generated.

However, as shown in FIG. 5 or 6, when the tension roller 170 descends and becomes lower than the height of the tension roller 170 shown in FIG. 7, the upper protrusion 176 moves the second tension roller detection sensor ( 183 is interposed between the light emitting unit 184 and the light receiving unit 185 . In this case, since the light projected from the light emitting unit 184 does not reach the light receiving unit 185 , the detection signal of the second tension roller detection sensor 180 is not generated.

The controller 220 is the transfer unit 150 according to the position of the tension roller 170 sensed by the first and second tension roller detection sensors 180 and 183, the transfer speed at which the drug wrapping paper 4 is transferred. The electric motor 156 of the transfer unit 150 is controlled as much as possible. The controller 220 may be a controller of an automatic medicament packaging device including the medicament wrapping paper sealing device 10 (see FIG. 8 ) and the medicament wrapping paper discharging device 100 .

In other words, among the first and second tension roller detection sensors 180 and 183 , the combination of the tension roller detection sensors 180 and 183 that generate a detection signal and the tension roller detection sensors 180 and 183 that do not generate a detection signal Accordingly, the controller 220 grasps the height of the tension roller 170 . And, the controller 220 controls the electric motor 156 of the transfer unit 150 so that the higher the height of the tension roller 170, the transfer speed of the transfer unit 150 is gradually reduced. In addition, when a detection signal is not generated from both the first and second tension roller detection sensors 180 and 183 , the controller 220 determines that the conveying speed of the conveying unit 150 is at the upper side of the conveying unit 150 . Controls the electric motor 156 of the transfer unit 150 so as to be greater than the entry speed of the drug wrapping paper 4 entering the transfer unit 150.

Specifically, as shown in FIG. 5, the tension roller 170 is in contact with the first guide 168 and the second guide 169 with the drug wrapping paper 4 interposed therebetween, or the first guide 168 and When positioned at a low height close to the second guide 169 , neither the detection signal of the first tension detection sensor 180 nor the detection signal of the second tension detection sensor 183 are generated as described above. In this case, the transport speed of the drug wrapping paper 4 of the transport unit 150 is released from the drug wrapping paper sealing device 10 (see FIG. 8 ) and is about 5 than the entry speed of the drug wrapping paper 4 toward the transport unit 150 . The controller 220 controls the electric motor 156 to be set as large as %. This velocity becomes the default velocity of the transport velocity.

Therefore, the progressing speed of the drug wrapping paper 4 that proceeds in the transport unit 150 is smaller than the entry speed of the drug wrapping paper 4 that enters between the third pulley 164 and the tension roller 170, so that the drug wrapping paper 4 is There is no problem in that the process is stagnated by being rolled upstream of the transfer unit 150 . And, the tension of the drug wrapping paper 4 is too small, so the problem of being spaced apart from the outer peripheral surface of the roller body 172 of the tension roller 170 does not occur.

If, in the transfer unit 150, the progress speed of the drug wrapping paper 4 is increased so that the difference between the progress speed of the drug wrapping paper 4 and the entry speed of the drug wrapping paper 4 becomes larger, the drug wrapping paper 4 As shown in FIG. 6, the tension roller 170 rises as the magnitude of the tension increases. In this case, the detection signal of the first tension detection sensor 180 is generated and the detection signal of the second tension detection sensor 183 is not generated. The controller 220 controls the electric motor 156 so that the transport speed of the transport unit 150 in this case is smaller than the entry speed of the drug wrapping paper 4 . For example, a speed smaller than the entry speed of the drug wrapping paper 4 may be a speed of 50% of the initial set feed speed described above.

When the transport speed of the transport unit 150 is reduced through the control of the controller 220 and the progress speed of the drug wrapping paper 4 in the transport unit 150 is actually reduced, as shown in FIG. 5, the tension roller 170 is lowered again, and the feed rate of the transfer unit 150 is restored to the above-described initial set feed rate.

However, if the progress speed of the drug wrapping paper 4 is faster so that the difference between the speed of progress of the drug wrapping paper 4 and the entry speed of the drug wrapping paper 4 in the transfer unit 150 is not reduced, but becomes larger, the drug As the magnitude of the tension of the wrapping paper 4 increases, the tension roller 170 rises as shown in FIG. 7 . In this case, a detection signal is generated from both the first tension detection sensor 180 and the second tension detection sensor 183 . The controller 220 controls the electric motor 156 so that the transfer speed of the transfer unit 150 becomes 0 in this case.

When the transport speed of the transport unit 150 becomes 0 through the control of the controller 220 and the progress speed of the drug wrapping paper 4 in the transport unit 150 is actually reduced, tension as shown in FIG. 6 or FIG. 5 The roller 170 may descend again. However, despite the control of the controller 220, if the state in which the detection signal is generated from both the first tension detection sensor 180 and the second tension detection sensor 183 continues for a preset period of time, the controller ( 220) determines that a problem has occurred in the drug wrapping paper discharging device 100, and stops the operation of the drug wrapping paper discharging device 100 and the automatic drug packaging device including the same. When the operation of the automatic drug packaging device is stopped, the operator directly approaches the drug packaging paper discharging device 100 to identify and deal with the problem.

Accordingly, the drug wrapping paper 4 is more strongly in close contact with the wide belt 205 , so that the drug wrapping paper 4 does not slide against the wide belt 205 , and is reliably transported on the wide belt 205 .

On the other hand, when the drug wrapping paper 4 is frictionally supported by the wide belt 205 and proceeds in an upward inclined direction, the ends 213 of the plurality of inclined plates 212 are the drug pockets 6 of the drug wrapping paper 4 ( 1) is contacted. If a plurality of medicaments 1, 2 are overlapped within the medicament pocket 6 or the medicament pocket 6 is thickened because the medicaments 1 and 2 are erected, the end 213 of the swash plate 212 is As the medicaments 1 and 2 collide, the medicaments 1 and 2 are laid in one layer so that the medicament pocket 6 becomes thin.

Figure 8 is a perspective view showing an embodiment of the drug wrapping paper cutting unit provided in the drug wrapping paper discharging device of the present invention, Figure 9 is an enlarged perspective view of the drug wrapping paper cutting unit of Figure 8. 1 to 3, 8, and 9 together, the medicament wrapping paper cutting unit 110 is released from the medicament wrapping paper sealing device 10, a plurality of medicament pockets 6 are formed medicament wrapping paper (4) is cut into several to several tens of drug pockets (6). For example, the drug wrapping paper 4 may be cut so as to be divided by the patient receiving the drug, or by the date of taking the drug.

The drug wrapper cutting unit 110 is disposed between the first and second roller assemblies 25 , 45 of the drug wrapper sealing device 10 and the conveying unit 150 . The drug wrapping paper cutting unit 110 is a fixed blade (blade) 114, a rotating blade 116 that is coupled by a hinge 119 to one end of the fixed blade 114 and rotates, the rotating blade The medicament wrapping paper 4 in which the medicament pocket 6 is formed by passing between the electric motor 120 for the cutting unit which provides power to 116 rotate, and the said 1st and 2nd roller assemblies 25 and 45 is below It is provided with a discharge guide (guide) 112 for supporting the drug wrapping paper (4) so as to be discharged through the fixed blade (114) without being bent.

The fixed blade 114 and the electric motor 120 for the cutting unit are fixedly coupled to the frame of the medicament wrapping paper sealing device 10 for rotatably supporting the first and second roller assemblies 25 and 45. It is fixedly supported on the cutting unit support bracket 111 . The discharge guide 112 is integrally formed with the cutting unit support bracket 111 . The electric motor 120 for the cutting unit may be a BLDC motor that can precisely control the rotation speed of its motor shaft, and has a lower risk of electric shock than an AC motor.

The rotating blade 116 is rotatable between an open posture in which the angle with the fixed blade 114 is maximized with respect to the hinge 119 and a closed posture overlapping the fixed blade 114 . 8 and 9 disclose a rotating blade 116 in an open position. When the rotating blade 116 is in the open position, the drug wrapping paper 4 passes between the fixed blade 114 and the rotating blade 116, and the rotating blade 116 rotates in the open position and the fixed blade 114 and When the overlapping closed posture is applied, a shear force is applied to cut the drug wrapping paper (4).

The drug wrapping paper cutting unit 110 is a means for transmitting the rotational power of the electric motor 120 for the cutting unit to the rotating blade 116, and includes a crank 121 and a link 123. . The crank 121 is coupled to a motor shaft (not shown) of the electric motor 120 for the cutting unit and rotates coaxially. The crank 121 includes a link connecting protrusion 122 connected to the link 123 at an eccentric position from its rotational center. A link guide groove 124 into which the link connecting protrusion 122 is movably fitted is formed at one end of the link 123 . One end 117 of the rotating blade 116 , specifically, one end 117 that does not overlap with the fixed blade 114 when in a closed position can pivot on the other end of the link 123 . is closely connected With this configuration, when the crank 121 rotates one turn in the clockwise or counterclockwise direction, the rotating blade 116 returns to the open posture from the open posture through the closed posture.

The drug wrapping paper cutting unit 110 further includes a rotation blade detection sensor 126 for detecting whether the rotation blade 116 is in the open position. 8 and 9, the rotating blade detection sensor 126 is a photo sensor. A disc-shaped sensing disk 130 is fixedly coupled to the motor shaft of the electric motor 120 for the cutting unit and rotates coaxially with the crank 121 . A dent 131 dented toward the center is formed at an outer peripheral edge of one side of the sensing disk 130 . The rotating blade detection sensor 126, that is, the photo sensor receives a light emitting unit 127 for projecting light and the light projected from the light emitting unit 127 to generate a detection signal. and a light receiving unit 128 that generates the light. An outer periphery of the sensing disk 130 is interposed between the light emitting unit 127 and the light receiving unit 128 .

When the motor shaft of the electric motor 120 for the cutting unit rotates and the detection disk 130 rotates, every time the detection disk 130 rotates once, the light emitting unit 127 through the dent 131 is projected The light is received by the light receiving unit 128 to generate a sensing signal. Therefore, whenever the detection signal is generated, the controller 220 of the medicament wrapping paper discharging device 100 understands that the rotating blade 116 returns to the open posture through the closed posture.

If, even if the operation of the electric motor 120 for the cutting unit is not intentionally stopped, the next detection signal is not generated until a predetermined time has elapsed after the detection signal is generated in the light receiving unit 128, the controller 220 considers that an accident such as medicament (1,2) jammed or finger jammed has occurred between the fixed blade 114 and the rotating blade 116, and the rotating blade 116 returns to the open position until it returns, that is, The dent 131 is positioned between the light emitting unit 127 and the light receiving unit 128 to reversely rotate the motor shaft of the electric motor 120 for the cutting unit until the detection signal is generated again.

The drug wrapping paper cutting unit 110 rotates only one blade, that is, the rotating blade 116, and even if only the rotating blade 116 rotates relatively slowly, the shear force to cleanly cut the drug wrapping paper 4 is sufficiently secured. Because it can, the noise is significantly reduced during the cutting operation of the drug wrapping paper 4, and even if the operator's finger is inadvertently caught between the fixed blade 114 and the rotating blade 116, a safety accident such as finger cutting occurs I never do that. In addition, the rotation blade detection sensor 126 is provided so that even if the medicines 1 and 2 or fingers are caught between the fixed blade 114 and the rotation blade 116, the rotation blade 116 is automatically returned to the open position. , work can be resumed quickly, and damage to the electric motor 120 for the cutting unit is prevented.
