An example of such an automatic medicine dispensing device is disclosed in Patent Document 1, for example. In the automatic medicine dispensing device described in Patent Document 1, the medicine is discharged from the medicine storage section that stores the medicine to the belt conveyor, and the medicine discharged to the belt conveyor is conveyed to the dispensing section.

  In such an automatic medicine dispensing device, it is necessary to manage the dispensing of the medicine from the medicine storage unit to the dispensing unit in order to make the application determined for each patient. In the above conventional automatic medicine dispensing device, a reflection type optical sensor is provided below each medicine container, and by detecting the discharge of the medicine from the medicine container, the medicine is discharged from the medicine container to the dispensing part. I manage the payout.

Japanese Patent Laid-Open No. 10-265052

  However, in the conventional automatic medicine dispensing device, for example, when the medicine dispensed from the medicine storage unit is transparent and this medicine is contained in a transparent container, the optical sensor cannot detect the medicine itself. Sometimes. For this reason, it may not be possible to manage the dispensing of medicines from the medicine storage unit to the dispensing unit.

  Therefore, an object of the present invention is to provide an automatic medicine dispensing device that can reliably manage the dispensing of medicine from the medicine storage section to the dispensing section.

  An automatic medicine dispensing apparatus according to one aspect of the present invention is a medicine automatic dispensing apparatus that dispenses medicine from a medicine storage section in which medicine is stored to a dispensing section, and a storage unit main body that stores medicine supplied from the medicine storage section; The storage unit is openably and closably provided at the lower part of the storage unit body, and has an open / close unit that discharges the medicine stored in the storage unit body to the dispensing unit, and is connected to the storage unit, and is vertically A detection unit that detects the displacement of the liquid, a moving mechanism that moves the storage unit and the detection unit integrally in the vertical direction, and a management unit that manages the dispensing of the medicine to the dispensing unit based on the displacement detected by the detection unit And.

  In the automatic medicine dispensing device with this configuration, the detection unit is connected to a storage unit that is moved in the vertical direction by a moving mechanism. In the detection part, the displacement at the time of storing the medicine in the storage part can be detected. Therefore, by using the displacement detected by the detection unit, it is possible to manage the dispensing of the medicine to the dispensing unit. For example, based on the change in displacement in the detection unit before and after opening / closing the opening / closing unit, it is determined whether or not the medicine is discharged from the storage unit, or the weight is stored in advance for each type of medicine, By comparing the weight converted from the displacement detected by the stored weight with the stored weight, it is possible to determine whether or not the type of medicine stored in the reservoir is appropriate. Can manage the payout. Thereby, even if it is a transparent medicine which cannot be detected by an optical sensor or the like, the delivery of the medicine to the dispensing section can be managed. That is, it is possible to reliably manage the dispensing of the medicine from the medicine storage unit to the dispensing unit.

  In one embodiment, the management unit may determine whether or not the medicine is discharged from the storage unit based on a change in displacement in the detection unit before and after opening and closing the opening and closing unit.

  In the automatic medicine dispensing device, for example, even when the opening / closing part is opened, the label stuck to the medicine container may be caught by the opening / closing part and not discharged. In the medicine automatic dispensing device having this configuration, it is possible to reliably determine whether or not the medicine has been discharged from the storage section. Therefore, the medicine to be dispensed is determined for each patient by the medicine remaining in the storage section. It is possible to reliably detect the case where the application is not applied.

  Moreover, in one embodiment, it further includes a storage unit that associates and stores the weight for each type of medicine, and the management unit includes a weight converted from a displacement detected by the detection unit when the medicine is stored in the storage unit. The weight associated with the medicine to be stored in the storage unit read from the storage unit may be compared to determine whether or not the type of medicine stored in the storage unit is appropriate.

  In the medicine automatic dispensing device having this configuration, whether the medicine stored in the storage unit or the dispensed medicine is a medicine for application determined for each patient, It is possible to check whether or not the quantity is to be used. Thereby, it is possible to reliably detect the case where the medicine dispensed to the dispensing unit is not applied for each patient.

  In one embodiment, the detection of the displacement in the detection unit may be performed while the moving mechanism moves the detection unit at a constant speed.

  In the medicine automatic dispensing device having this configuration, it is possible to acquire the vertical displacement in a state where influences of disturbance such as rattling, acceleration, speed change and wind pressure are eliminated as much as possible.

  Moreover, in one Embodiment, a storage part has the 1st storage part and the 2nd storage part which is arrange | positioned under the 1st storage part and a chemical | medical agent is supplied from a 1st storage part, and is detected. The part has a first detection unit connected to the first storage unit and a second detection unit connected to the second storage unit, and the second storage unit is vertically located above the dispensing unit. The first storage part may be arranged so as to be movable between the medicine storage part and the second storage part.

  In this medicine automatic dispensing device, the first storage unit moves the medicine supplied from the medicine storage part to the second storage part, and the second storage part delivers the medicine supplied from the first storage part. To move. By configuring the automatic medicine dispensing device in such a configuration, the moving distance of the second storage unit is shorter than that of the first storage unit, and it is possible to secure a long stop time. Thereby, in the 2nd detection part connected with the 2nd storage part, it is possible to acquire the displacement of the up-and-down direction in the state where the influence of disturbances, such as rattling by movement, acceleration, speed change, and wind pressure, was excluded. Become. As a result, the weight of the medicine stored in the second storage unit can be acquired with high accuracy. In addition, the first detection unit connected to the first storage unit is less likely to obtain vertical displacement in a state in which the influence of disturbance due to movement is excluded compared to the second detection unit connected to the second storage unit. Even if it is, the presence or absence of discharge can be determined. This is because the determination of the presence or absence of discharge does not require detection accuracy as high as when determining whether or not the type of medicine is appropriate. Therefore, it is possible to detect the discharge of the medicine even while the first detection unit is being moved by the movement mechanism. Thus, by sharing the role between the first storage unit and the second storage unit, it becomes possible to dispense the medicine with high efficiency and high accuracy.

  In one embodiment, the movement mechanism supports a guide member extending in the vertical direction, a drive unit moving in the vertical direction along the guide member, and a storage unit and a detection unit movably along the guide. The drive unit may be moved in the vertical direction along the guide member in a state where the support unit is placed.

  In the medicine automatic dispensing device having this configuration, the support portion is simply placed without being fixed to the drive portion. In other words, in the medicine automatic dispensing device with this configuration, the drive unit and the storage unit can move independently. Therefore, when the lower end of the storage unit comes into contact with the medicine or the like and is prevented from moving downward, only the driving unit on which the support unit is placed is moved downward. Thereby, for example, when the lower end of the storage unit comes into contact with a medicine or the like, it is not forcibly pushed down, so that occurrence of breakage of the medicine or the like can be reduced.

  In one embodiment, the storage part is provided so as to discharge the medicine stored in the storage part main body, and the opening / closing part opens when the opening / closing part is opened by at least one of its own weight and the weight of the medicine. The restraint part may further be provided so that the presence or absence of restraint on the opening / closing part can be switched.

  In the medicine automatic dispensing device having this configuration, the storage part is lowered to a position where the stored medicine is discharged, and the restriction of the opening / closing part is released when the medicine is lowered to the point. And by raising a storage part, an opening-and-closing part is opened gradually, and a chemical | medical agent is discharged | emitted from a storage part main body. Thereby, the fall distance of a chemical | medical agent can be shortened as much as possible, and damage to a chemical | medical agent can be reduced.

  According to the present invention, it is possible to reliably manage the dispensing of medicines from the medicine storage unit to the dispensing unit.

  The first load cell 37 is provided at a position where the slide bar 21 and the first hopper 31 are connected to each other, and detects the vertical displacement of the first hopper 31 relative to the slide bar 21. The first load cell 37 is moved together with the first hopper 31 by the first moving mechanism 20.

  The second moving mechanism 40 is a mechanism for moving the second hopper 51, which will be described in detail later, in the vertical direction (the vertical direction shown in FIGS. 1 and 2). The second moving mechanism 40 has a cylinder 41 and a piston rod 43. The piston rod 43 is provided so as to be movable in the vertical direction (the vertical direction shown in FIGS. 1 and 2). More specifically, the piston rod 43 is supplied to the cylinder 41, and can move in the arrow direction D3, for example, by air pressure or hydraulic pressure. With this configuration, the second hopper 51 is movable in the vertical direction (the vertical direction shown in FIGS. 1 and 2) above the dispensing unit 70.

  The second hopper 51 is a part for storing the injection 7 discharged from the first hopper 31. The second hopper 51 is provided so as to be openable and closable at a second hopper body (storage body) 53 for storing the injection 7 discharged from the first hopper 31 and a lower portion of the second hopper body 53. 2 It has the 2nd gate (opening-closing part) 55 which discharges the injection 7 stored by the hopper main body 53 to the dispensing part 70. As shown in FIG.

  The second load cell 57 is provided at a position where the piston rod 43 and the second hopper 51 are connected, and detects the displacement of the second hopper 51 in the vertical direction with respect to the piston rod 43. The second load cell 57 is moved together with the second hopper 51 by the second moving mechanism 40.

  The dispensing part 70 is a part from which a predetermined type and / or quantity of the injection 7 is dispensed via the first hopper 31 and the second hopper 51. In the injection automatic dispensing device 1 of the present embodiment, the transport tray T is disposed in the dispensing unit 70. The conveyance tray T may be configured to be automatically conveyed to the dispensing unit 70 by a conveyance device or the like, or may be arranged by a human hand.

  The control device 80 is a part for controlling various operations in the automatic injection drug dispensing device 1 and includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk, and the like. As shown in FIG. 3, the control device 80 has a management unit 81 as a conceptual part that executes various control processes of the injection automatic dispensing device 1. The functions executed by such a conceptual part are executed under the control of a CPU or the like. In addition, the control device 80 further includes a storage unit 83 that stores weights in association with each type of injection 7.

  The management unit 81 is a part that manages the dispensing of the injection 7 to the dispensing unit 70 based on the displacements detected in the first load cell 37 and the second load cell 57, respectively. Specifically, the management unit 81 determines whether or not the injection 7 has been discharged from the first hopper 31 based on a change in displacement detected in the first load cell 37 before and after opening and closing the first gate 35. judge.

  In addition, the management unit 81 stores the weight converted from the displacement detected by the second load cell 57 when the injection 7 is stored in the second hopper 51 and the second hopper 51 read from the storage unit 83. By comparing with the weight associated with the injection 7 to be determined, it is determined whether the type and / or quantity of the injection 7 stored in the second hopper 51 is appropriate.

  The input / output unit 17 is a part that receives input from the user and displays various information. Examples of information input by the user include information including the type and / or quantity of the injection 7 for predetermined application (hereinafter referred to as “prescription information”). The input / output unit 17 outputs information received from the user to the control device 80.

  Next, operation | movement in the injection automatic dispensing device 1 which concerns on 1st Embodiment is demonstrated. When the injection automatic dispensing device 1 receives the prescription information via the input / output unit 17, it starts the dispensing process of the injection 7. Specifically, the control device 80 moves the first hopper 31 to the position of the supply cassette 15B in which the injection 7 to be prepared is stored based on the prescription information. In this position, the first hopper 31 receives a supply of the injection 7 to be prepared.

  Next, the control apparatus 80 moves the 1st hopper 31 which received supply of the injection 7 to the upper position in which the 2nd hopper 51 is arrange | positioned. The movement of the first hopper 31 is accelerated at a predetermined acceleration and then decelerated at a predetermined acceleration through a predetermined constant speed section. The management unit 81 may store the displacement detected in the first load cell 37 that is moving in the constant speed section.

  Next, the control device 80 causes the second hopper 51 to discharge the injection 7 stored in the first hopper 31. The management unit 81 discharges the injection 7 from the first hopper 31 to the second hopper 51 based on the change in displacement detected by the first load cell 37 before and after discharging the injection 7 to the second hopper 51. It is determined whether or not it has been done. When the management unit 81 determines that the injection 7 is not normally discharged, the control device 80 may display the fact on the input / output unit 17 or interrupt the dispensing process, for example. .

  Further, the management unit 81 detects the displacement detected by the first load cell 37 after the injection 7 is discharged to the second hopper 51 and the first load cell 37 during the movement in the constant speed section stored previously. Whether or not the injection 7 has been discharged from the first hopper 31 to the second hopper 51 may be confirmed based on the displacement that has been made. In this case, since the vertical displacement obtained in the state where the influence of disturbance such as rattling, acceleration, speed change and wind pressure is eliminated as much as possible is used, was the injection 7 discharged more accurately? You can check whether or not.

  Next, the second hopper 51 receiving the supply of the injection 7 from the first hopper 31 is moved downward until the second gate 55 comes to a position near the bottom surface of the transport tray T. The movement of the second hopper 51 is accelerated at a predetermined acceleration and then decelerated at a predetermined acceleration through a predetermined constant speed section. The management unit 81 stores the displacement detected in the second load cell 57 that is moving in the constant speed section.

  Next, the control device 80 discharges the injection 7 stored in the second hopper 51 to the transport tray T. The management unit 81 should prepare (store) the weight converted from the displacement detected in the second load cell 57 during the movement in the constant speed section and the second hopper 51 read from the storage unit 83. The weight associated with the injection 7 is compared to determine whether the type and / or quantity of the injection 7 stored in the second hopper 51 is appropriate. Here, when the control device 80 determines that the injection 7 to be prepared by the management unit 81 has not been discharged, for example, the control device 80 displays that fact on the input / output unit 17 or interrupts the dispensing process. May be.

  In the injection automatic dispensing device 1 according to the first embodiment, the first load cell 37 is connected to the first hopper 31 that is moved in the vertical direction by the first moving mechanism 20, and the second load cell 57 is The second moving mechanism 40 is connected to a second hopper 51 that is moved in the vertical direction. The first load cell 37 can detect a displacement when the injection 7 is stored in the first hopper 31. Further, the second load cell 57 can detect a displacement when the injection 7 is stored in the second hopper 51. Therefore, it can be determined whether or not the injection 7 has been discharged from the first hopper 31 based on the change in the displacement of the first load cell 37 before and after opening and closing the first gate 35 in the first hopper 31. Further, by comparing the weight converted from the displacement detected by the second load cell 57 with the weight associated with the injection 7 to be stored read from the storage unit 83, the weight is stored in the second hopper 51. It can be determined whether the type and / or quantity of the injection 7 that is present is appropriate. Thereby, even if it is the transparent injection 7 which cannot be detected with an optical sensor etc., the discharge of the injection 7 to the discharge part 70 can be managed. That is, the dispensing of the injection 7 from the injection storage unit 15 to the dispensing unit 70 can be reliably managed.

  Moreover, in the injection automatic dispensing device 1 according to the first embodiment, the first hopper 31 is configured to be movable in the vertical and horizontal directions, and the second hopper 51 is movable in the vertical direction above the dispensing unit 70. Is arranged. In other words, the second hopper 51 is provided for the purpose of discharging in a state where the second hopper 51 is lowered so as to be as close as possible to the dispensing unit 70 (conveyance tray T). Therefore, the first hopper 31 moves the injection 7 supplied from the injection storage 15 to the second hopper 51, and the second hopper 51 delivers the injection 7 supplied from the first hopper 31. To move. For this reason, compared with the 1st hopper 31, the moving distance of the 2nd hopper 51 becomes short, and it can ensure the time when the 2nd hopper 51 has stopped. Thereby, in the second load cell 57 connected to the second hopper 51, it is possible to acquire the vertical displacement in a state where the influence of disturbance such as rattling due to movement, acceleration, speed change and wind pressure is excluded. Become. As a result, the weight and / or quantity of the injection 7 stored in the second hopper 51 can be obtained with high accuracy.

  In addition, since it is sufficient to determine whether or not the injection 7 is discharged, it is only necessary to obtain a large vertical displacement in the first hopper 31, and therefore, the influence of disturbance due to movement compared to the second load cell 57 connected to the second hopper 51. It is possible to determine even the first load cell 37 connected to the first hopper 31 in which the vertical displacement is difficult to obtain in a state where the above is excluded. Thus, by sharing the role between the first hopper 31 and the second hopper 51, it becomes possible to dispense the injection with high efficiency and high accuracy.

(Second Embodiment)
Next, an automatic injection dispensing device 101 according to the second embodiment will be described with reference to FIGS. The automatic injection dispensing device 101 of the second embodiment is different from the automatic injection dispensing device 1 described above in the method of opening and closing the gate (opening / closing unit) in the first gate part and / or the second gate 55. Here, the description of the same or equivalent configuration as the automatic injection drug dispensing device 1 of the first embodiment is omitted, and a configuration different from the automatic injection drug dispensing device 1 will be described.

  Here, the first hopper 31 will be described as an example. The first hopper 31 is provided so as to discharge the injection 7 stored in the first hopper body 33 when the first gate 35 is opened by at least one of its own weight and the weight of the injection 7. It has a restraining portion 71 that restrains the gate 35 from opening.

  Specifically, as shown in FIG. 4, the first gate 35 of the first hopper 31 is formed by two plate-like members 35 </ b> A and 35 </ b> B having one end formed in a comb-teeth shape. The plate-like members 35A and 35B are pivotally supported by the first hopper body 33 so that the other end thereof is rotatable, and the first hopper 31 is closed by engaging one of the comb-like ends with each other. In other words, a state in which the injection 7 can be stored in the first hopper body 33 is formed. Further, the two plate-like members 35A and 35B are pivotally supported on the first hopper body 33 so as to rotate in the opening direction by at least one of its own weight and the weight of the injection 7.

  The restraining portion 71 is a portion that restrains (blocks) the two plate-like members 35A and 35B from rotating in the opening direction by at least one of their own weight and the weight of the injection 7, and switches the presence or absence of restraint. Yes, it has a holding unit 73 and a switching unit 75.

  The holding part 73 is a member that restrains the two plate-like members 35 </ b> A and 35 </ b> B that rotate in the opening direction by at least one of their own weight and the weight of the injection 7. The holding portion 73 is pivotally supported by the first hopper main body 33 and is supported by the first hopper main body 33 at the holding member 73B provided in contact with the lower surface of the first gate 35 and the holding member 73B. A roller 73 </ b> A provided at the end opposite to the side on which it is present.

  The switching unit 75 is a member that switches presence / absence of restraint in the holding unit 73. The switching unit 75 includes a link unit 75B that is formed of a plurality of rotating units and linear units and restricts the movement of the roller 73A, and a fulcrum unit 75A that switches the state of the link unit 75B by a driving device such as an actuator. doing.

  In the first hopper 31 configured as described above, when the injection 7 is stored in the first hopper body 33, the link portion 75B restrains the movement of the roller 73A as shown in FIG. That is, the first gate 35 is restricted so as not to open. When the injection 7 is discharged from the first hopper body 33, as shown in FIG. 5, the fulcrum part 75A is moved by the drive device, and the position of the link part 75B is moved downward. When the link portion 75B is in such a state, the roller 73A is in a free state in which there is no restriction to rotate in the opening direction. Thereby, as shown in FIG. 6, the first gate 35 rotates in the opening direction by at least one of its own weight and the weight of the injection 7. Then, the injection 7 stored in the first hopper body 33 is discharged from the first hopper body 33.

  When closing the first gate 35, the fulcrum portion 75A may be moved by the driving device. As a result, the link portion 75B rises to the position shown in FIG. 4 and restrains the roller 73A again. That is, the first gate 35 is restricted from rotating in the opening direction, and the closed state is maintained.

  In the injection automatic dispensing device 201 of the second embodiment, the first hopper 31 is lowered to a position for discharging the stored injection 7, and the restriction of the first gate 35 is released when the first hopper 31 is lowered to the point. The In this state, by raising the first hopper 31, the first gate 35 is gradually opened, and the injection 7 is discharged. Thereby, the fall distance of the injection 7 can be shortened as much as possible, and damage to the injection 7 can be reduced.

(Third embodiment)
Next, an automatic injection medicine dispensing device (medicine automatic dispensing device) 201 according to the third embodiment will be described with reference to FIGS. The automatic injection dispensing device 201 of the third embodiment is different from the automatic injection dispensing device 1 described above in that the first moving mechanism 20 and / or the second moving mechanism 20 that moves the first hopper 31 and the second hopper 51 in the vertical direction. This is a configuration of the moving mechanism 40. Here, the description of the same or equivalent configuration as the automatic injection drug dispensing device 1 of the first embodiment is omitted, and a configuration different from the automatic injection drug dispensing device 1 will be described.

  Here, the first moving mechanism (moving mechanism) 220 that moves the first hopper 31 will be described as an example. As shown in FIG. 7, the first moving mechanism 220 includes a rail (not shown) and a slide bar (guide member) 223. The rail is arranged so as to extend in the horizontal direction, and the slide bar 223 is arranged so as to extend in the vertical direction. That is, the slide bar 223 is provided to be movable in the horizontal direction with respect to the rail.

  The first moving mechanism 220 is driven by a motor (not shown), and is provided with a driving unit 225 movably provided in the vertical direction D31 along the slide bar 223, a first hopper (storage unit), and a first And a support portion 227 that supports the load cell (detection portion) so as to be movable along the slide bar 223. The first hopper 31 is provided so as to be movable in the vertical direction D32 along the slide bar 223 via a support portion 227 placed on the drive portion 225.

  The first load cell (detection unit, first detection unit) 237 is provided at a position connecting the slide bar 223 and the first hopper 231, more specifically, between the support unit 227 and the first hopper 31. Thus, the vertical displacement of the first hopper 31 relative to the support portion 227 is detected. The first load cell 237 is moved together with the first hopper 31 by the first moving mechanism 220.

  In such a configuration, the drive unit 225 can move the first hopper 31 in the vertical direction by moving in a state where the support unit 227 is placed.

  In the injection automatic dispensing device 201 of the third embodiment, the support part 227 and the drive part 225 are not fixed, and the support part 227 is only placed on the drive part 225. That is, in the injection automatic dispensing device 201 having this configuration, the drive unit 225 and the first hopper 31 connected to the support unit 227 can move in the vertical direction independently of each other. Therefore, for example, as shown in FIG. 8, when the lower end 31A of the first hopper 31 comes into contact with the injection 7 and the like and is prevented from moving downward, the side on which the support portion 227 is placed is placed. Only the drive unit 225 moves in the downward direction D33.
