Description

Drug Distributing Apparatus for Automatic Drug Packing System

The present invention relates to a medicine dispensing apparatus of an automatic medicine packing machine, and more particularly, a medicine dispensing having a function of dispensing and dispensing medicine from a medicine container according to a predetermined condition in an automatic medicine packaging device that automatically dispenses and packages medicine. Relates to a device.

In general, the conventional medicine packing machine is largely divided into a pharmaceutical or powder dispensing device and packaging device, the dispensing device is divided into a manual dispensing method for dispensing medicine directly by a pharmacist and an automatic dispensing method for automatic dispensing. It is also divided into manual packing method and automatic packing method.

In this case, the number of pharmacies is increasing in size as the total number of pharmacies decreases in order to be competitive since the division of medicine is conducted, but it is difficult to increase the size in small pharmacies located in residential areas. In addition, small residential pharmacies will have more time and patients to deal with over-the-counter prescriptions than patients and hospitals.

By the way, small pharmacies are still a manual packaging because the cost of purchasing the automatic medicine packaging machine is also burdened, especially the automatic drug dispensing device is more expensive and is not equipped with this.

Therefore, when the time required for dispensing and packaging a medicine becomes long, a lot of patients who want to purchase the medicine through a consultation without a prescription are inconvenient to wait a long time.

In addition, the process of dispensing the drug is to increase the pharmacist's fatigue, and it is desirable to devote more time to the medication guidance for the patient to save time by reducing the drug dispensing time as much as possible, and during manual dispensing by the pharmacist Dispensing / packaging of multiple days of medicine can lead to incorrect packaging due to inadvertent or incorrect manual dispensing.

Moreover, when a pharmacist directly dispenses a medicine, this may cause the pharmacist to become addicted to the medicine. There will be variables that can be affected.

Most medicine packaging machines have been proposed to handle the medicine dispensing process manually and to process only the packaging automatically (Utility Registration No. 235084 or Utility Registration No. 179161). As disclosed in Korean Patent Laid-Open Publication No. 2002-25644, when the tablet / powder storage chamber is intermittently moved and positioned at a predetermined setting position, the tablet / powder is dropped by opening an opening and closing plate installed at the bottom.

However, the automatic drug dispensing device must use a dedicated product having a predetermined size and structure set in the tablet / pharmaceutical storage room in which tablets and drugs are stored. Discomfort exists to be transferred to the drug storage room.

Moreover, these conventional automatic drug dispensing apparatuses are mostly included only in large-capacity processing apparatuses for automatically dispensing and packaging drugs, and these large-capacity processing apparatuses are expensive equipment and can be provided only by large pharmacies. These devices have a problem in that the structure is very complicated for automation and failure occurs frequently.

In addition, the automatic drug dispensing device is a method of opening and closing the plate installed on the bottom of the dedicated tablet storage chamber (that is, the medicine container) to drop the medicine from the lower portion to distribute the medicine to the predetermined position to move the motor and a plurality of gears. It is essentially provided with a driving device using. Therefore, in the conventional automatic medicine dispensing device, a problem occurs that noise is greatly generated by driving of the motor and gear of the medicine cabinet.

On the other hand, in order to improve the problems of the prior art as described above, "Applicant's automatic contact dispenser using an air drive type moving head" filed by the applicant on May 23, 2002, the application number 10-2002-0028735 As a method of driving using compressed air, a method of using compressed air as a power source for driving the movable head and taking out the medicine has been proposed.

However, 10-2002-0028735 uses the compressed air generated by the compressor as the driving force of the movable head, and the ejection of the medicine from the medicine cabinet is operated by using the negative pressure, so that the compressed air generating source and the negative pressure generating source are simultaneously used. There was an inefficient operational problem that had to be managed.

Therefore, the present invention is conceived in view of the problems of the prior art, the purpose of which is to drive the drive unit of the dispensing device of the automatic medicine packaging device for automatically taking out and packaging the medicine tablets stored in the medicine container according to a predetermined condition as an electric motor The present invention provides a medicine dispensing device for an automatic medicine packing machine that improves the operation reliability of the device while simplifying the device configuration by treating the medicine extraction from the medicine box by the suction pressure while driving.

The medicine container fixing part is installed below the take-out part, while the medicine bottle 10 is detachably installed, the medicine 11 taken out of the medicine bottle by the take-out part falls and is delivered to the hopper 250. Have.

The medicine container fixing part is composed of a dispensing hopper 170, a fixed base, a medicine holder, and the like.

One side of the dispensing hopper 170 is fixed to the bracket 110, and the hopper 250 receives the medicine 11 dropped out of the vial 10 by the discharging end 124 of the dispensing part 124. An outlet 174 leading to) is formed at the bottom thereof.

In addition, a drop sensor 172 is installed at an inner lower end of the distribution hopper 170 to detect a medicine falling and to check whether the medicine is normally taken out.

The fixed base is mounted on one side of the base 160, the base 170, one end of which is connected to the lower end of the fixed hopper 170 to transfer the vibration to the vial 10 to help withdraw the medicine smoothly The first holder 162 and the second holder 163 and the first holder 162 and the first holder 162 for fixing the vial 10 are installed on the upper surface of the vibrator 166 and the base 160 so as to be movable in opposite directions. First holder extension 162a and second holder extension which are formed at each lower end and protrude to the bottom of the base 160 to move the holder 162 and the second holder 163 in directions facing each other. A moving shaft 164a which is screwed to the part 163a, the first holder extension 162a and the second holder extension 163a, and one end thereof is fixed to the lower surface of the base 160 so that the moving shaft The first support portion 165a for supporting the middle of the (164a), one end is fixed to the lower surface of the base 160 For example, a second support part 165b supporting one end of the moving shaft 164a and a rotation shaft connected to the other end of the moving shaft 164a and a main body fixed to one end of the lower surface of the base 160 are moved shafts. A fixed motor 164 for rotating 164a in the forward and reverse directions, a first vial sensor 162c installed in the middle of the first holder 162, and a second vial sensor installed in the middle of the second holder 163. 163b and a vial switch 167 which reversely rotates the fixed motor 164.

The first holder extension 162a and the second holder extension 163a which are connected to the first holder 162 and the second holder 163 may move in the center of the base 160 in the front-rear direction. The path 161a is formed.

As shown in FIG. 4B, the movable shaft 164a is formed with screws in different directions about the first support part 165a. That is, if the left side portion of the first support portion 165a is formed with the right screw, the right side portion of the first support portion 165a is formed with the left screw so that the movable shaft 164a is moved in one direction by the fixed motor 164. Even if turned to the first holder extension 162a and the second holder extension (163a) to be able to move in a direction facing each other.

In addition, the operation of the fixed motor 164 is controlled by the first vial sensor 162c, the second vial sensor 163b, the vial switch 167, the control unit 500, according to the mounting of the vial 10 The control process is as follows.

While the user presses the vial switch 167 on, the fixed motor 164 is rotated forward by the control unit 500 to open the first holder 162 and the second holder 163.

When the first holder 162 and the second holder 163 are wide enough to mount the vial 10, the vial switch 167 is turned off to stop the operation of the fixed motor 167. .

When the first holder 162 and the second holder 163 are opened at a sufficient distance, when the user attaches the vial to the first holder 162 in close contact, the vial 10 is connected to the first vial sensor ( 163c) is turned on.

The controller 500 reversely rotates the fixed motor 164 when the first vial sensor 163c is turned on. When the fixed motor 164 rotates in reverse, the first holder 162 and the second holder 163 approach each other, so that the second side opposite to the vial 10 in close contact with the first holder 162. The holder 163 is in close contact with each other, thereby turning on the second vial sensor 163b mounted on the second holder 163.

When the second vial sensor 163b is turned on, the control unit 500 stops the reverse rotation of the fixed motor 164 that is in the reverse rotation, thereby completing the mounting and fixing of the vial 10.

Here, the first holder 162 and the second holder 163 is installed so that the base 160 is inclined (the first holder side down), the first holder 162 is greater than the height of the vial 10 The length of the second holder 163 is relatively short since the second holder 163 only needs to fix the lower end of the vial 10.

Since the first holder 162 is inclined downward as described above, the vial 10 is in close contact with the first holder 162 in the mounting process of the vial 10 as described above, so that the first vial sensor ( Even though the first holder 162 and the second holder 163 are narrowed while the 162c is turned on, the first holder 162 is a result of the upward movement, and thus the first holder 162 may be caused by gravity applied to the vial 10. Since the close contact between the 162 and the vial 10 is maintained, the first vial sensor 162c is not turned off while the vial 10 is moving.

Most of the shapes of the vial 10 mounted on the first holder 162 and the second holder 163 are cylindrical, but sometimes there are also a vial having a rectangular barrel structure.

Therefore, in order to accurately operate the first vial sensor 162c and the second vial sensor 163b by the vial 10, the structures of the first holder 162 and the second holder 163 are based on the center. It should be an obtuse structure with an angle of at least 90 degrees.

Referring to the operation of the drug delivery device configured as described above is as follows.

The user must mount the vial containing the medicine required for the preparation to each of the plurality of dispensers 101, the mounting process of the vial 10, the control unit 500 is fixed while turning on the vial switch 167 The first holder 162 and the second holder 163 are opened to each other so that the vial 10 can be mounted by rotating the motor 164 forward.

Since the first vial sensor 162c is turned on when the vial 10 is attached to the first holder 162 in close contact with the vial 10, the control unit 500 rotates the fixed motor 164 to reverse the first holder 162. And the second holder 163 approaches each other. When the first holder 162 and the second holder 163 approach each other and the second holder 163 is in close contact with the vial 10, the second vial sensor 163b is turned on so that the control unit 500 controls the fixed motor. Stop the reverse rotation of (164) to complete the vial mounting process.

In the above description and the accompanying drawings, the shape of the vial 10 is illustrated as an example, and thus, the mounting direction of the vial does not need to be set in a specific direction, but when the shape of the vial is a square barrel, the corner portion of the vial The first holder 162 and the second holder 163 need to be mounted so as to be in close contact with the inner edge portions.

Then, in order to form a negative pressure necessary for taking out the medicine by the dispensing unit of each dispenser 101, the negative pressure means 131 must be operated in advance before the apparatus is used to form a sufficient negative pressure.

As described above, in the state in which the plurality of medicine bottles 10 are respectively installed in the plurality of medicine container fixing parts, the user sets the number of packages of the pharmaceutical preparations using the panel 400 and inputs the unit packaging medicine for each dispenser 101. When the number of medicines to be set is set using the dispensing setting unit 230 which can set the number of medicines to be set, the set number is displayed on the dispensing display unit 231, and at this time, the dispenser is operated every time the dispenser 101 operates. An operation light 232 is displayed.

When the setting is completed as described above, data about the number of medicines to be prepared, the number of medicines to be added for each unit package, and the like are delivered to the control unit 500.

Then, when the start button 415 is pressed, the control unit 500 removes the medicines 11 from the respective medicine bottles 10 in a predetermined order and delivers the medicines 11 to the packaging unit 200 through the hopper 250.

The drug extraction process for each vial is as follows.

Before taking the medicine, the slider 142 of each dispenser 101 remains stationary at the upper end of the frame 112. At this time, the contact portion 148 at the upper end of the slider 142 is in contact with the contact sensor 147, and the control unit 500 indicates that the contact portion 148 is in contact with the contact sensor 147. It is determined that the slider 142 is located at the top of the frame 112.

The control unit 500 moves the slider 142 downward by the driving belt 146 when the driving motor 140 drives the medicine 11 to take out the medicine 11 from the medicine bottle 10 according to the preparation setting. The negative withdrawal tube 120 enters the vial 10. Here, before entering the dispensing tube 120 into the vial 10, the vibrator 166 mounted on the dispenser 101 equipped with the vial 10 to be withdrawn is operated to move the medicine in the vial 10 to either side. It should not be biased.

That is, the vibrator 166 diversifies the position of the medicine in order to increase the probability that the medicine 11 in the medicine bottle 10 is adhered to the dispensing end 124 of the ejection part by transmitting a physical vibration to the medicine bottle 10. Act to give.

The control unit 500 opens the solenoid valve 130 connected to the negative pressure means 131 through the first to third negative pressure lines 138, 136, and 132 before entering the draw tube 120 into the vial 10. To convert the pressure in the draw tube 120 to a negative pressure, and then the draw tube 120 must enter the vial 10.

When entering the medicine bottle 10 with the negative pressure formed in the take-out tube 120 as described above, the medicine 11 is attached to the receiving portion 124a formed in the take-out end 124.

As the inflow of air suddenly decreases at the moment when the medicine 11 is attached to the receiving portion 124a of the blowout end 124 as described above, a strong negative pressure is suddenly formed in the negative pressure line. 134 is detected.

Therefore, the controller 500 determines whether the medicine 11 is attached to the receiving portion 124a of the take-out end 124 through the instantaneous change in the negative pressure sensed by the vacuum sensor 134, and the driving motor 140. ) To stop the entry of the extraction tube (120).

Then, the driving motor 140 is rotated in reverse to move the slider 142 upward.

When the slider 142 moves to the top, the contact portion 148 contacts the contact sensor 147. When the signal is input from the contact sensor 147, the controller 500 determines that the slider 142 is the top movement of the slider 142. The motor 140 is stopped.

Here, in some cases, while the slider 142 is moved downward by the drive motor 140, that is, even in a state in which the dispensing end 124 is in contact with the medicine 11 in the vial 10 The state that is not attached to the receiving portion 124a of the take-out end 124 may be caused.

In this case, since the medicine 10 is not attached to the receiving portion 124a of the discharging end 124, the driving motor 140 continues to operate, and the slider 142 continues to move downward accordingly. .

Therefore, since the slider 142 cannot be moved downward because the ejection end 124 is prevented from moving forward by the medicine 11 in the vial 10, the driving motor 140 is overloaded. .

In order to solve this problem, the present invention provides an overload sensor (not shown) in the drive motor 140, and the overload detection sensor when the overload is induced in the drive motor 140 due to the above state. It is determined that the state in which the downward movement of the slider 142 is hindered by the failure of the medicine 11 is stopped, and the forward rotation of the driving motor 140 is stopped to stop the downward movement of the slider 142. After rotating the slider 142 slightly up and holding it for about 1 second, it is again rotated again and the slider 142 is moved downward again, and the extraction of the medicine 11 is attempted again.

As described above, when the slider 142 moves to the uppermost end with the medicine 11 attached to the receiving portion 124a of the dispensing end 124, the discharging end 124 is positioned above the dispensing hopper 170 on a vertical line. Will result.

In this state, the control unit 500 closes the solenoid valve 130, and when the solenoid valve 130 is closed, the negative pressure is removed, and the drug is attached to the receiving portion 124a of the discharge end 124 by the negative pressure. Naturally, 11 falls to the gravity direction, ie, the distribution hopper 170.

At this time, the drug (11) attached to the receiving portion (124a) of the dispensing end (124) is strongly adhered to the receiving portion (124a), and may not be separated even if the negative pressure is removed. The medicine 11 is separated by the ejector driver 121 and the ejector 122 formed between the 120 and the ejection end 124.

That is, since the ejector drive plate 122a is pushed by the repulsive force of the spring 121a constituting the ejector driver 121 to push the ejector 122, the ejector 122 positioned at one end in the center of the ejection end 124. By (11) is to be separated by pushing.

Therefore, the suction force formed by the negative pressure necessary to take out the medicine 11 should be sufficiently larger than the repulsive force formed by the spring 121a.

As described above, the medicine 11 falling on the dispensing hopper 170 impacts the drop sensor 172 installed on the inner bottom of the dispensing hopper 170 so that the control unit 500 finally drops the normal dropping portion of the medicine 11. To judge.

The control unit 500 controls the other dispenser 101 for dispensing the next medicine when the drop of the medicine 11 is normally made through the drop sensor 172, but if the medicine 11 is not normally taken out and falls, Try again, and if this error is repeated, alert the user to take action.

As described above, the medicine 11 dropped in the dispensing hopper 170 is introduced into the hopper 250 through the outlet 174 formed at the lower end of the dispensing hopper 170 and transported to the packing part 200.

The medicine 11 transferred to the packaging part 200 is packaged together with other medicines according to the preparation setting.

The present invention made as described above is made by the motor of the medicine dispenser for dispensing and dispensing each medicine from the medicine bottle in an automatic medicine packaging machine that automatically takes out the medicine from the medicine bottle as set according to the preparation history of the medicine As a result, the operation reliability of the device is increased, and the ejection power for taking out the medicine uses the negative pressure caused by vacuum, thereby preventing the breakage of the medicine and improving the reliability of the packaging.

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and the general knowledge in the technical field to which the present invention belongs without departing from the spirit of the present invention. Various changes and modifications will be made by those who possess.
