The tonic unit also has the same control method.
As shown in the figure, a plurality of the tonic units can constitute a tonic group, and the tonic group is at least one, or two or more. For example, the group of remedies has a drawer-like pull-out mechanism, so that the group of remedies can be pulled out separately as a unit relative to the unit for storing the medicines. Specifically, the pulling-out mechanism comprises a sliding rail arranged at the bottom or the side of the herbal supplement unit, and the herbal supplement unit can be pulled out along the sliding rail.

The drug supplementing group comprises a plurality of drug supplementing units separated by partition plates, and the supplemented drugs are stacked and stored in the drug supplementing units of the drug supplementing group in a classified manner.
The plurality of medicine supplementing units and the medicine storage units have corresponding relations, namely the medicine storage units and the medicine supplementing units which store the same medicine or consumable materials have corresponding relations. For example, the tonic group has 8 tonic units, which are respectively C1 to C8, the medicine storage units take 8 in two rows as an example, the codes of the medicine storage units in the first row are respectively a1-a4, and the codes of the medicine storage units in the second row are B1-B4, when corresponding, a one-to-one correspondence relationship may be adopted, that is, 8 tonic units correspond to 8 medicine storage units, or a non-one-to-one correspondence relationship may also be adopted, for example, the C1 tonic unit, the C2 tonic unit, and the a1-a2 medicine storage unit all store the same medicine or consumable, and then the C1 tonic unit and the C2 tonic unit establish a correspondence relationship with the a1-a2 medicine storage units at the same time. If the number of the medicine storage units is larger than that of the medicine supplementing units, a corresponding relation is established between one medicine supplementing unit and a plurality of medicine storage units, for example, the medicine supplementing group comprises 8 medicine supplementing units from the C1 medicine supplementing unit to the C8 medicine supplementing unit, the number of the medicine storage groups is eight, each medicine storage group comprises 8 medicine storage units, and each medicine supplementing unit can be set to correspond to 8 medicine storage units of one medicine storage group. And the corresponding relation between the medicine supplementing unit and the medicine storage unit is stored in a memory of the control unit. Meanwhile, the coordinate position of the medicine supplementing unit of the medicine supplementing group on the XY axis plane adopts the same determining method as that of the medicine storing unit, and the coordinate of each medicine supplementing unit on the XY axis plane is determined, so that the three-coordinate medicine transporting unit can be controlled to move the medicine taking head to the position above the appointed medicine supplementing unit. The coordinate positions of the medicine replenishing units of the medicine replenishing group in the XY-axis plane are also stored in the memory of the control unit. Since the memory of the control unit stores the coordinate positions of each medicine supplementing unit and each medicine storing unit on the XY-axis plane, the control unit can easily control the medicine taking head to move between the medicine storing unit and the medicine supplementing unit of the medicine supplementing group.

In particular, the side supports are side plates.
The medicine replenishment unit will be described in detail below. Get it filled mechanism and include that a plurality of medicines mend a position unit, every stores up medicine unit and mends the medicine unit and have a medicine and mend a position unit, the medicine is mended a position unit and is included lifting means, supporting component and driver part to store up the medicine unit as an example, like the one embodiment of the medicine position unit that figure 7 shows, lifting means is vertical lifting belt 3-1 who sets up, lifting belt 3-1 includes many, and every stores up medicine unit and corresponds a lifting belt 3-1, the top of many lifting belts all is on same horizontal plane. The support component is a lifting tray 3-3, the lifting tray 3-3 is horizontally arranged, the medicine boxes 10 in the medicine storage unit are stacked on the lifting tray 3-3 to form a medicine stack, one end of the lifting tray 3-3 is fixed on the lifting belt 3-1, the drive component is a lifting motor 3-2, the lifting belt 3-1 can move up and down in the vertical direction under the driving of the lifting motor 3-2, and the lifting tray 3-3 supports the medicine boxes in the stacked state to move up and down. The top of the lifting belt 3-1 is provided with a medicine position supplementing sensor 3-4, the medicine position supplementing sensor 3-4 can detect height information of medicine boxes at the top of the medicine storage unit, namely height information of the medicine boxes at the top of the medicine stack on the lifting tray 3-3, and sends the height information of the medicine boxes at the top to the control unit. Because the top ends of the plurality of lifting belts are all on the same horizontal plane, and the top of each lifting belt is provided with the medicine filling position sensor 3-4, the medicine filling position sensors 3-4 are basically on the same plane.
One embodiment of the medicine filling position sensor 3-4 is shown in fig. 4, the medicine filling position sensor 3-4 comprises a light emitter and a light receiver, the light emitter and the light receiver are arranged side by side, when a top medicine box of a medicine box stack on the lifting tray 3-3 reaches the height of the medicine filling position sensor, detection light emitted by the light emitter is reflected by the medicine box and then received by the light receiver, the light receiver sends reflected light information to a control unit, and the control unit obtains the height of the top medicine box of the medicine box stack on the lifting tray reaching the medicine filling position sensor according to the transmitted light information; when the top medicine box of the medicine box stack on the lifting tray 3-3 is taken away by the medicine taking head, the light receiver cannot receive the detection light reflected by the medicine box, and the control unit cannot receive the reflected light information, so that the control unit judges that the top medicine box of the medicine box stack on the lifting tray 3-3 does not reach the height of the medicine position supplementing sensor. When the medicine taking head takes the medicine in the medicine storage unit away, as shown in fig. 5, the medicine storage unit with the medicine taken away is in a medicine shortage state, the control unit cannot receive the information of reflected light sent by the medicine position supplementing sensor 3-4 at the top of the medicine storage unit, therefore, the control unit judges that the top medicine box of the medicine box stack on the lifting tray 3-3 of the medicine storage unit does not reach the height of the medicine position supplementing sensor 3-4, the control unit controls the lifting motor 3-2 to drive the lifting tray 3-3 to ascend until the top medicine box of the medicine box stack on the lifting tray 3-3 reaches the height of the medicine position supplementing sensor 3-4, the control unit receives reflected light information sent by the medicine position supplementing sensor 3-4 at the top of the medicine storage unit again, and the control unit controls the lifting motor 3-2 to stop driving the lifting tray 3-3 to ascend. Through the control, the medicine boxes at the top in each medicine storage unit can be ensured to be generally positioned on the same horizontal plane.
Similarly, the medicine replenishing unit and the medicine storing unit have the same medicine replenishing function, that is, each medicine replenishing unit also has a medicine replenishing unit, so that the medicine boxes at the top in the medicine replenishing units are all positioned on the same horizontal plane. If the cost is reduced, the medicine supplementing group can be designed to have the same structure as a single medicine storage group, and only the medicine supplementing group is provided with a pulling-out mechanism and can be pulled out horizontally relative to the medicine storage group, so that the universality of the equipment can be improved, and the medicine boxes on the tops of the medicine storage group and the medicine supplementing group are positioned on the same horizontal plane. In another embodiment, the drug storage group and the drug supplementation group have the same structure, that is, the drug storage group and the drug supplementation group both have a pull-out mechanism, in this case, one or more of the drug storage groups are actually used as drug supplementation groups, that is, the drug storage group which cannot be pulled out due to locking of the pull-out mechanism is used as a drug storage space, and the drug storage group which can be pulled out due to unlocking of the pull-out mechanism is used as a drug supplementation space.
This has the additional advantage that the medicine replenishment unit 3 places the top cassette in each storage unit substantially at the same level. For example, after the control unit receives a medicine taking instruction for taking a medicine in the a2 medicine storage unit, the control unit needs to control the three-coordinate medicine taking unit to move the medicine taking head to be right above the a2 medicine storage unit and suck the topmost medicine box in the a2 medicine storage unit, the control unit only needs to determine the coordinate displacement of the medicine taking head on the XY axis according to the number of the medicine storage unit, the Z axis (namely the longitudinal displacement of the medicine taking head) only needs to descend by a fixed height value without considering whether each medicine storage unit is lack of medicine, and a special contact sensor is not needed to be arranged on the medicine taking head to determine whether the medicine taking head descends to the height of the medicine box, so that the situation that the medicine box is damaged due to excessive longitudinal displacement of the medicine taking head or the medicine taking head is not damaged due to insufficient longitudinal displacement and the medicine taking fails is prevented. Meanwhile, the design can enable the displacement control of the medicine taking head to be very simple, and after the control unit receives the medicine taking instruction, the corresponding medicine storage unit and the displacement of the medicine taking head on the three axes of XYZ can be found out from the database at once without any calculation. Similarly, taking a drug from a patch unit would have the same benefits.
Further, the medicine supplementing position sensor 3-4 can also realize medicine shortage alarm of the medicine storage unit or the medicine supplementing unit. Taking a medicine storage unit as an example, when the control unit cannot receive reflected light information sent by the medicine position supplement sensor 3-4 at the top of the medicine storage unit, the control unit controls the lifting motor 3-2 to drive the lifting tray 3-3 to ascend, if the lifting motor 3-2 drives the lifting tray 3-3 to ascend by a specified height, such as the whole height of a medicine storage space of the medicine storage unit, the control unit cannot still receive the reflected light information sent by the medicine position supplement sensor 3-4 at the top of the medicine storage unit, the fact that all medicines in the medicine storage unit are taken away is indicated, the control unit sends medicine lack information of the medicine storage unit, and the medicine lack information can be transmitted to the outside and also can be displayed on a display screen or can be used for alarm prompt through sound and light. On the other hand, because the height of the lifting part is determined by the stroke of the driving part, the control unit can know the height of the lifting part through the stroke of the motor, so that the quantity of the missing medicines in the medicine storage unit is further known, and when the quantity of the missing medicines reaches a certain threshold value, the control unit sends the medicine shortage information of the medicine storage unit.

The support component comprises a clamping plate and a lifting tray 3-3, the clamping plate and the lifting tray 3-3 are horizontally arranged, the clamping plate is arranged above the lifting tray, medicine boxes 10 in the medicine storage unit are stacked on the clamping plate to be stored to form a medicine stack, one end of the lifting tray 3-3 is fixed on a sliding block 3-6, the driving component is a lifting motor 3-2, the sliding block 3-6 can move up and down along the vertical direction on a lead screw 3-5 under the driving of the lifting motor 3-2, and the lifting tray 3-3 supports the medicine boxes in the stacked state to move up and down. The top of the screw rod 3-5 is provided with a medicine position supplementing sensor 3-4, and the medicine position supplementing sensor 3-4 can detect the height information of the top medicine box of the medicine stack on the lifting tray 3-3 and send the height information of the top medicine box to the control unit. As the top ends of the plurality of screw rods 3-5 are all on the same horizontal plane, and the top of each screw rod 3-5 is provided with the medicine position supplement sensor 3-4, the medicine position supplement sensors 3-4 are basically on the same plane.
The utility model discloses carry out the step as follows of mending to storage medicine unit:
the method comprises the following steps: the control unit enters a medicine supplementing mode of the medicine storage unit; the medicine storage unit medicine supplementing mode can be started by an operator or can be automatically started by the control unit, and the control unit can obtain the medicine shortage information of the medicine storage unit, so that the control unit can enter the medicine storage unit medicine supplementing mode when the quantity of medicines of one or more medicine storage units or the quantity of certain medicines is reduced to a preset stock threshold, and the medicine taking function is temporarily stopped in the mode.
Step two: the control unit determines a medicine storage unit needing medicine supplement, searches a medicine supplement unit corresponding to the medicine storage unit needing medicine supplement, and judges whether the corresponding medicine supplement unit has medicine, if so, the step three is executed, and if not, the step six is executed; since the memory of the control unit stores the corresponding relationship between the medicine storage unit and the medicine supplement unit, for example, the medicine supplement unit A2 needs to supplement the medicine, the control unit obtains the medicine supplement unit corresponding to the medicine storage unit A2 as the medicine supplement unit C2, and the medicine or consumable part identical to the medicine storage unit A2 is stored in the medicine supplement unit C2. And because each medicine supplementing unit is provided with a medicine supplementing unit, the control unit can also acquire the medicine shortage information of any medicine supplementing unit, namely, whether the medicine exists in the C2 medicine supplementing unit corresponding to the A2 medicine storage unit needing medicine supplementing or not can be known, and if the medicine exists in the C2 medicine supplementing unit, the control unit can control the medicine moving unit to supplement the medicine or consumable materials in the C2 medicine supplementing unit to the A2 medicine storage unit.
Step three: the control unit controls the lifting tray of the medicine storage unit needing medicine supplement to descend, the descending height is h, and the height of a single medicine stacked and stored in the medicine storage unit is h; thus, the stack of drugs in the a2 unit is lowered by the height of one drug cassette as a whole, and if the a2 unit does not already contain any drugs, its lifting tray is located at the top of the a2 unit, which is lowered by the height of one drug cassette, also freeing up the storage space for one drug cassette.
Step four: the control unit inquires a medicine storage unit needing medicine supplement and the coordinate position of the corresponding medicine supplement unit, controls a medicine taking head of the medicine conveying unit to move to the top of the medicine supplement unit corresponding to the medicine storage unit needing medicine supplement, takes the medicine at the top of the medicine supplement unit away from the medicine taking head, moves to the top of the medicine storage unit needing medicine supplement, releases the medicine to complete the process of supplementing the medicine from the medicine supplement unit to the medicine storage unit, meanwhile, a medicine position supplementing unit of the medicine supplement unit enables a lifting tray of the medicine supplement unit to lift, the lifting height is h, and the medicine on the medicine supplement unit and the tops of other medicine supplement units generally return to the same horizontal plane again;
step five: the control unit controls the medicine conveying unit to return to the initial position and executes the step two;
step six: the control unit sends out the suggestion that the medicine is lacked to the unit of making up medicine. In this case, since the medicine storage unit of the medicine vending machine is short of a certain amount of medicine and the replenishing unit is not replenished with the medicine, the medicine in the medicine vending machine needs to be replenished and an operator needs to fill the replenishing unit with the medicine.
Further, the utility model discloses the benefit medicine step to the benefit medicine unit as follows:
the method comprises the following steps: the control unit enters a medicine supplementing mode of a medicine supplementing unit and determines the medicine supplementing unit needing medicine supplementation; the medicine supplementing mode of the medicine supplementing unit is started by an operator, in the mode, the operator needs to open the shell of the medicine selling machine, and the medicine taking function is temporarily stopped.
Step two: the lifting tray of the medicine supplementing unit needing to be supplemented descends to the lowest position, when the medicine in the medicine supplementing unit at the lowest position is in the maximum storage amount, the position of the lifting tray is located, the medicine supplementing unit is provided with the medicine position supplementing unit, the tops of medicine stacks on the lifting tray of the medicine supplementing unit needing not to be supplemented are all at the same horizontal height, the lifting tray of the medicine supplementing unit needing to be supplemented descends to the lowest position, the tops of the medicine stacks on the lifting tray can be lower than those of other medicine supplementing units, or the medicines on the lifting tray are all taken away, so that an operator can visually see which medicine supplementing units need to be supplemented, and the number of the medicine lacking can be estimated approximately.
Step three: pulling out the tonic group to be supplemented; the said tonic group is pulled out separately from the medicine storage group. Specifically, because the utility model discloses a tonifying medicine unit includes that the medicine mends a position sensor, therefore the control unit learns the scarce medicine information of tonifying medicine unit, and the tonifying medicine personnel open after selling the medicine machine, according to lack medicine information and pull out the tonifying medicine group that corresponds, if tonifying medicine group only one, then only need directly pull out this tonifying medicine group can.
Step four: the operator fills the medication into the unit of the supplement to be supplemented and pushes the set of supplements back into place. In this step, the number of the medicines filled by the medicine filling unit cannot exceed the maximum capacity of the medicine filling unit, that is, the height of the medicine stack on the lifting tray cannot exceed the height of the medicine filling sensor of the medicine filling unit.
Step five: the control unit controls the medicine boxes at the top of the medicine supplementing units in the medicine supplementing set to be substantially positioned on the same horizontal plane; specifically, if the medicine stock of a certain medicine replenishing unit still does not reach the maximum stock after the medicine replenishing operation, namely the top of the medicine stack on the lifting tray is still lower than the height of the medicine position supplementing sensor, the lifting motor drives the lifting tray to ascend until the medicine box at the top of the medicine stack on the lifting tray reaches the height of the medicine position supplementing sensor, and the lifting is stopped.
Step six: the control unit finishes the medicine supplementing mode of the medicine supplementing unit, and the medicine selling machine can normally take the medicine.
In the method, the medicine in the medicine storage unit is taken by the medicine selling machine when the medicine is taken, if the medicine is lacked in the medicine storage unit, the medicine is supplemented into the medicine storage unit from the medicine supplementing unit, and when the medicine supplementing personnel supplement the medicine for the medicine selling machine, the supplemented medicine is not directly put into the medicine storage unit but is filled into the medicine supplementing unit. The advantage of doing so lies in if still have the medicine that has not got up in the medicine storage unit, then medicine migration unit takes the medicine that remains in the medicine storage unit at first after, moves into the medicine storage unit with the medicine of newly filling from the unit of making up a prescription again for taking, can guarantee like this that the medicine of filling earlier is taken earlier, prevents the loss that the medicine is outdated and causes.
Further, the medicine selling machine further comprises a device area 9 inside, and preferably, the device area 9 is located below the medicine storage unit. The equipment area 9 is used for installing refrigeration equipment, storage units and the like.
It is understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can conceive of changes or substitutions within the technical scope of the present invention.
