The auditing machine 300 receives the sachet 118 from the inlet 302. The conveyance unit 530D controls the first conveyance roller 304 and the second conveyance roller 306 to convey the packaging bag 118 to the imaging region. The imaging unit 530A controls the light source 312, the first camera 308, and the second camera 310, images the medicine in the packaging bag 118 from the up and down directions, and acquires the medicine image 508C.

The auditing unit 530B acquires drug data 508B including an image from the prescription data 508A. The auditing unit 530B determines whether the audit target medicine is the same as the medicine shown in the prescription data 508A from the medicine data 508B and the medicine image 508C, and outputs information on the audit result 508D. The printing unit 530C controls the label printer mechanism 316, and affixes the label on which the prescription data and the information obtained by the inspection unit 530B are printed to the packaging bag 118. The conveyance unit 530D controls the third conveyance roller 332. The third transport roller 332 discharges the labeled packaging bag 118 to the storage box 400 through the discharge port 334.

As described above, the conveyor 200 adjusts the difference in processing speed between the packaging machine 100 and the inspection machine 300.

Next, a preferred embodiment of the medicine audit support system 10 will be described. The controller 500 preferably instructs the packaging machine 100 to package the medicine based on the audit result 508D of the auditing machine 300.

For example, when the audit result 508D is “the medicine in the sachet bag 118 and the prescription data 508A do not match”, the sachet bag 118 determined as not matching (referred to as an unseparable sachet) is not used. As a result, the required sachet 118 is insufficient. Based on the audit result 508D, the controller 500 controls the wrapping machine 100, and the wrapping machine 100 newly supplements the wrapping paper 112 based on the prescription data of the inseparable wrapping bag in order to compensate for the insufficient wrapping bag 118. Divide into. According to the medicine inspection support system 10, the missing sachet 118 is automatically replenished.

FIG. 5 is a partially enlarged view of the auditing machine 300. The same components as those of the auditing machine 300 shown in FIG.

As shown in FIG. 5, the inspection machine 300 includes a passage detection sensor 342 and a perforation forming machine 344 between the discharge port 334 and the third transport roller 332 from upstream to downstream.

Generally, the perforating machine 100 is provided with a perforation forming machine. However, the perforation of the packaging bag 118 may cause unintentional cutting of the packaging bag 118 during the transportation of the packaging machine 100, the transport machine 200, and the inspection machine 300. The cutting of the packaging bag 118 during transportation causes the packaging bag 118 to be clogged by the packaging machine 100, the transportation machine 200, and the inspection machine 300. The clogging also causes a failure of the packaging machine 100, the transport machine 200, and the inspection machine 300. Moreover, in order to eliminate clogging, it is necessary to stop any of the packaging machine 100, the conveyance machine 200, and the inspection machine 300. The throughput of the medicine inspection support system 10 is reduced.

The inspection machine 300 shown in FIG. 5 includes a perforation forming machine 344 that forms perforations in the continuous sachets 118 after the audit. The perforation forming machine 344 of the inspection machine 300 can prevent the packaging bag 118 from being cut due to the perforation during conveyance. The perforation forming machine 344 is preferably disposed upstream or downstream of the third transport roller 332 that is a discharge roller. Since the packing bag 118 in which the perforation is formed is discharged from the downstream discharge port 334, the tension applied to the perforation of the packing bag 118 can be reduced. As a result, unintentional cutting of the packaging bag 118 can be suppressed.

The third camera 330 detects the vertical seal part. Since the packaging bag 118 is transported to the transport unit 530D based on the position of the vertical seal portion, the packaging bag 118 can be aligned with the label attaching position and the perforation forming position.

The perforation forming machine 344 includes a first perforation blade (not shown) having a plurality of protruding blades and a second perforation blade (not shown) having a hole for receiving the protruding blade of the first perforation blade. The A perforation is formed in the vertical seal portion by sandwiching the first perforation blade and the second perforation blade in the vertical seal portion of the packaging bag 118.

The passage detection sensor 342 shown in FIG. 5 is a detector that detects the movement of one package. For example, the passage detection sensor 342 can detect a label attached to the packaging bag 118 and confirm passage of one packaging bag 118. As the passage detection sensor 342, a reflection type sensor and a transmission type sensor can be applied. For example, a reflective sensor and a transmissive sensor include a light emitting unit and a light receiving unit.

When the inspection machine control unit 530 detects the passage of one package 118, information is transmitted to the transport machine control unit 520. Based on the result of the passage detection sensor 342, the transport machine control unit 520 controls the transport machine 200. The transporting machine 200 receives a single packaging bag 118 from the packaging machine 100. By making the speed of the packaging bag 118 discharged from the inspection machine 300 substantially coincide with the speed discharged from the packaging machine 100, the difference in processing speed can be adjusted.

FIG. 6 is a partially enlarged view of the packaging machine 100 and the transport machine 200. As shown in FIG. 6, the packaging machine 100 includes a switching mechanism 130 that switches the path of the packaging bag 118. The switching mechanism 130 includes an introduction port 132 of the packaging bag 118, a discharge port 134 of the packaging bag 118, and a movable conveyance path 136 between the introduction port 132 and the discharge port 134. The movable conveyance path 136 has a fulcrum 138 on the side of the packaging machine 100. The movable conveyance path 136 can move up and down around a fulcrum 138 within a predetermined range.

In FIG. 6, when the movable conveyance path 136 is in the horizontal position, the packaging bag 118 discharged from the packaging machine 100 passes through the movable conveyance path 136 and is received by the conveyance machine 200 through the introduction port 202. The packaging bag 118 is sent out from the transport device 200 to the inspection device 300. Therefore, the packaging bag 118 is switched to a route for sending it to the inspection machine 300.

When the movable conveyance path 136 is inclined obliquely downward from the horizontal position around the fulcrum 138, the packaging bag 118 discharged from the packaging machine 100 passes through the movable conveyance path 136 and is stored in the storage box 400. The Therefore, it is possible to switch to a route for sending the sachet 118 out of the inspection machine 300.

When the auditing machine 300 cannot be used due to a failure or the like, the user can use only the packaging machine 100.

[Third Embodiment]
A third embodiment will be described with reference to FIG. Note that parts having the same functions as those of the first and second embodiments are denoted by the same reference numerals, and detailed description thereof is omitted. Mainly, the buffer part is different from the other embodiments. The configuration will be described.

FIG. 11 is a schematic configuration diagram of the transporter 200 of the medicine inspection support system 10. In FIG. 11, the packaging machine 100, the inspection machine 300, and the controller 500 are omitted.

As illustrated in FIG. 11, the transporter 200 includes a casing 201 having an introduction port 202 and a discharge port 224, a pair of first transport rollers 204, and a pair of second transport rollers from upstream to downstream. 206, a folding mechanism 250, a pair of third transport rollers 240, and a pair of fourth transport rollers 246.

The folding mechanism 250 includes a pair of movable conveyance rollers 252 and a position detection sensor 254. The folding mechanism 250 functions as a buffer unit. The folding mechanism 250 is a mechanism in which folding edges are formed in the packaging bag 118 for each predetermined length and stacked. The predetermined length can be set as appropriate according to the size of the transporter 200 and the like.

As shown in FIG. 11, the pair of movable transport rollers 252 can reciprocate in the horizontal direction.

The packaging bag 118 conveyed from the packaging machine 100 passes through a pair of movable conveyance rollers 252 that continuously reciprocate in the horizontal direction, and is sent out to the lower side of the conveyance machine 200. As a result, the sachet 118 is accumulated in the folding mechanism 250 while being stacked in a zigzag shape by the pair of movable conveyance rollers 252.

The packaging bag 118 is conveyed from the lower side of the folding mechanism 250 to the inspection machine 300 (not shown) by the third conveyance roller 240 and the fourth conveyance roller 246.

By accumulating the packaging bags 118 in a zigzag shape in the folding mechanism 250, the difference in processing speed between the packaging machine 100 (not shown) and the inspection machine 300 can be adjusted. The position detection sensor 254 can detect whether or not the sachet 118 has reached the maximum allowable range.

In the first to third embodiments, it is preferable that a tension adjusting mechanism (not shown) is provided in the transport device 200 to apply a constant tension to the packaging bag 118. When the packaging bag 118 is sent out from the packaging machine 100, the packaging bag 118 sags. The tension adjusting mechanism operates to apply a certain tension to the sachet 118. The packaging bag 118 is pulled by the transporter 200 and received by the transporter 200. Therefore, the conveyor 200 can accept the packaging bag 118 in synchronization with the discharge of the packaging bag 118 from the packaging machine 100.

For example, a dancer roller can be applied as the tension adjustment mechanism. By applying a load to the rotating shaft that supports the dancer roller, the tension of the packing bag 118 is determined.
