200819205 IX. OBJECTS OF THE INVENTION: 1. Field of the Invention The present invention relates to a powder dispensing device used in a bulk medicine packaging machine that divides a powder into a predetermined amount and packaged it. "Month [Prior Art] ψ 15 20 The well-known bulk drug dispensing machine is a disk in which a peripheral groove having a circular cross section is formed in the phase material. The disk can be rotationally driven from the drug supply to the deer device. The external supply of the rotating disc is discharged and placed in a package-packaged ground, which is supplied to the external office for discharge, and is provided for the package, and the package-package is used for the shock. The powder supply device is provided with a _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ After the supply of the drug from the powder supply device to the disk = after the start of the drug, every time a predetermined time elapses, the phase moves: raw, grooved, and vibrated. By this control, it is increased from the medicine tank to the circle = (supply per unit time from the medicine tank to the outer circumference of the disc) __. However, in this control, by the setting of the time interval of the movement, the vibration value is increased 隼 = Γ! Γ point 'The thickness of the powder which is deposited on the outer peripheral groove is the thickness of the powder which is deposited on the outer peripheral groove. Deviation, then remove the first package and the most German, then rotate the disk at the same interval angle of the $$ packet, and pass the two-difference two-thick part of the multi-discharge phase, and on the other hand, the accumulation The thickness of the thin part is 5, and the amount of the medicine is reduced to become an error between the sub-packages. In addition, if the position where the vibration value is increased is concentrated at a certain point of the outer peripheral groove, the error becomes large, and the error between the sub-packages becomes large. Patent Document 2 discloses that the vibration generator controls the vibration applied to the medicine tank 5 so that the flow velocity of the powder medicine flowing from the medicine tank into the outer circumferential groove of the disk is constant. Specifically, the powder is supplied to the disk. At the time of the application, relatively strong vibration is applied from the vibration generator to the medicine tank, and the vibration applied to the medicine tank from the vibration generator is weakened by the decrease in the residual amount of the powder in the medicine tank and the supply hopper (h〇pper). Such control makes the overall supply However, in this control, there is the following problem. If it is a loose drug that is easy to flow, a large amount of powder-drug is supplied to the peripheral groove shortly after the start of supply, resulting in an uneven amount of accumulation. Conversely, if it is not easy In the case of the flow of the powder, there is a problem that it takes a long time to supply all of the powder to the outer peripheral groove of the disk.

In order to increase the supply rate of the drug from the scattered drug supply device, it is possible to increase the supply rate of the drug in advance. Further, the amount of accumulation is increased by two. Further, for example, when the powdered medicine located in the groove portion is discharged from the discharge hoof and supplied to the powder medicine packaging portion, the angle η of the groove portion is again 5 weeks. The amount of sputum discharged ^ makes Xiao Lai find the supply of the 15 = two. In addition, the angle reaches the set angle, and then the 庑 迅 迅 迅 《 《 《 《 《 《 迅 供 供 供 供 供 供 供 供 供 供 供 迅速 迅速 迅速 迅速 迅速 迅速 迅速 迅速 迅速 迅速When it is raised, the time required to supply the powder to the groove portion can be shortened. In general, it is preferable that the cumulative value of the set angle is set at a position different from each other in the groove portion. By setting the set angle in this way, the stacking is performed. The addition position is not repeated, and is distributed in a plurality of positions in the circumferential direction. As a result, the distribution of the amount of the bulk drug deposited in the groove portion can be accurately quantized. Therefore, the discharge device can be more accurately discharged. The desired powder is supplied to the powder medicine packaging department, and high-precision split packaging can be realized. ° More specifically, the setting angle is preset and cannot be divided by 360 degrees. The angle of 200819205 is used as an alternative. Benchmark setting angle, plus or Subtracting c== is the division of 360 degrees divided by the number of quotients of a natural number. For example, the control device preferably rotates the rotating body to a set angle at the rotation angle: After the degree of or after the degree, the supply from the powder supply device to the groove portion is increased. The control is difficult to perform by the fourth (4), and the accumulation amount is increased at a plurality of positions in the circumferential direction of the groove portion. It is possible to accurately repeat the uniformity of the distribution of the bulk amount of the powdered drug. The above-mentioned supply device includes, for example, a supply hopper for dispensing impurities, a medicine tank provided at a lower portion of the supply hopper, and vibration is applied to the medicine tank. A vibration generator that drops the powder to the groove portion of the rotating plate. At this time, the control device increases the intensity of the vibration applied to the medicine tank by the vibration generating device when the rotation angle reaches the set angle. 15 20 The supply hopper of the powder supply device is supported such that the gap between the medicine tank and the supply hopper can be increased or decreased, and the powder supply device can further include a gap adjusting device for vertically reducing the gap. At this time, if the cumulative rotation angle reaches the set angle, the control device increases the gap. The angle detecting means may be an encoder or an instrument for counting the number of driving pulses supplied to the pulse motor. The control device further includes an input device that manually inputs a plurality of set angles, and the control device checks a set angle input from the input device, and if the input set angle is repeated, the input is prohibited. According to the powder dispensing device of the present invention, it is possible to predict in advance the position in the circumferential direction of the annular groove portion where the amount of the drug accumulation increases, by increasing the amount of the drug from the drug: (_ quantity increase

By increasing the supply amount when the product rotation angle reaches the set speed, it is possible to: The amount of the powder supply to the groove portion of the gj disk is rapidly increased, and the time required for the drug to supply the powder to the groove portion is reduced. Especially if it is fixed? There are a plurality of collision angles, and the supply positions of the respective cumulative rotation angles at the set angles are set at positions different from each other in the circumferential direction of the sample portion ω, and the increase in the amount of accumulation may not be heavy, and may be dispersed to the groove. Multiple locations in the circumferential direction of the section.

The angle detecting device 34 is provided with the detected portion % and the element: = 36, and is set to the angle control motor (10). Further, in the outer portion of the detected portion 36, a plurality of magnets are attached at regular intervals. The magnetic force generated by the magnet 35 is detected, and the rotational angle position of the rectangular shaft 33a is detected.

Further, (4) the supply device 8A is provided with (4) the mechanism 38 for (4) the supply hopper 21 intermittently 2 (the t, the bucket striking mechanism 38 is provided with a solenoid 39 example common hopper strike = 40. The base end side of the supply hopper striking member 4G The output shaft fixed to the solenoid 39 is said. If the solenoid 39 is actuated, the end of the supply hopper striking member 40 hits the side of the supply hopper 21, and an impact is applied. The 'slot 22 is disposed in the supply hopper 21 The lower side is extended in the horizontal direction, and the front end 22a thereof is bent downward. The medicine tank a is screwed to the medicine tank support is member 41. The hammer member 42 is fixed to the bottom of the medicine tank support member 41. The medicine tank support member 41 is connected to the piezoelectric elements 14A, 14B, and the other ends of the piezoelectric elements 14A, 14B are connected to the fixed block 46. Moreover, the fixing 46 is fixed to the bracket. The bracket 45 is connected to the machine by four springs 44. When a voltage is applied to the piezoelectric elements 14A and 14B to expand and contract in the thickness direction, the medicine support member 41 applies a vibration of & = direction to the medicine tank 22. In order to detect the medicine tank 22 The applied vibration intensity, that is, the vibration output of the piezoelectric elements 14Α, 14Β, in the bracket 45 A vibration sensor 48 is disposed. Further, a balancer 49 for fixing the balance of the forward and backward movement of the carriage 12 200819205 when the piezoelectric elements 14A, 14A are driven is fixed to the rear end side of the bracket 45. As described above, a gap is provided between the lower end opening portion m of the supply hopper 21 and the medicine tank 22 =, and the loose music 2 fed from the upper end opening portion 21a to the supply hopper 21 is supplied from the gap to the _22. The powder medicine of the medicine tank 22, under the action of the vibration of the medicine tank 22, is moved to the front end melon, and falls from the front end melon to the disc 7A II, and the other is in the powder medicine The county set 8A is provided with a reflective diffuser 2 sense 115G' for detecting the presence or absence of loose music falling from the medicine tank 22 to the disc 7A. p Referring to the seventh figure, the powder medicine is divided into the control device 72 of the packaging device 1 and Preparing: fr and processing unit 74. The storage unit 73 stores the control required according to the information stored in the storage unit 73, corresponding to the from the m center 48, the powder drop detection sensing 11 5G, the angle detecting device 15 20 Spiral total ^ = input of various sensor types of 71A, 71B, control tired, 39, angle control motor%, The operation of the electrical component 14, (10), pulse = A, wide, discharge device 9, etc. The operator can be input to the storage unit 73 of the control device 72 via the operation panel (the input device #& For the control of the transmission and reception, etc., the control of the supply of the drug in the outer peripheral groove 10 of the bulk drug supply device 8A, which is executed by the control device 72, is described in detail. 72 monitors the cumulative value of the rotation angle (accumulated rotation angle 13 200819205 degrees) RAac from the disk 7A driven by the pulse motor 11A. Further, the control device 72 controls the amount of the powder supply from the powder supply device 8A to the outer circumferential groove 10 using the cumulative rotation angle RAac. The accumulated angle RAac can be detected by counting the number of pulses of the drive pulse supplied from the drive circuit 71A to the pulse motor 11A. For example, in the case where the disk 7A is rotated by 30 turns by 5,300,000 drive pulses, the 10,000-inch drive pulse is one rotation of the disk 7A (the cumulative rotation angle RAac is 360 degrees), and 15,000 drive pulses. For the rotation of the disc 7A, one rotation and 180 degrees (the cumulative rotation angle RAac is 540 degrees), 150,000 drive pulses are rotated 15 times (the cumulative rotation angle RAac is 54 degrees), 155,000 〇〇〇ίο The drive pulse is rotated 15 turns and 180 degrees (the cumulative rotation angle is 5580 degrees). Further, an encoder 76 (see Fig. 7) for detecting the rotation angle of the disk 7A may be provided, and the cumulative rotation angle RAac is detected by the encoder 76. Alternatively, the count of the drive pulses and the encoder 76 can be used simultaneously. The angle detection device for detecting the cumulative rotation angle of the disc 7A is not particularly limited, and includes a device having at least a pulse counter. Further, the 'female cumulative rotation angle RAac reaches a predetermined set angle RAs stored in the storage unit 73, and the control device 72 increases the voltage applied to the piezoelectric elements 14A, 14B by a certain amount, thereby increasing the piezoelectric elements 14A, 14B. The intensity of the vibration applied to the tank 22. When the vibration intensity is increased, the amount of the powder supply from the medicine tank 22 to the disk group increases. . The set angle RAs is set such that the cumulative rotation angle is not repeated from the front end position of the medicine tank 22 when the respective setting angles RAs are buckled, that is, the supply position of the powder medicine from the loose music supply device 8A to the outer circumferential groove 10 . That is, the set angle RAs is set so that the cumulative rotation angle is separated by at least about 2 degrees from the front end position of the medicine tank 22 from the buckle 14 200819205 to the respective set angles RAS. By setting the set body as described above, the circumferential direction position (the accumulation amount increase position) of the outer peripheral groove 1〇 in which the amount of the bulk drug accumulation is increased does not overlap. As a result, the distribution of the amount of the powder deposited in the circumferential direction of the outer peripheral groove 10 is uniformized by 5 degrees. By making the deposition amount distribution high-precision and uniform, it is possible to discharge a predetermined amount of the powdered medicine 'supplied to the powder medicine packaging unit 2' by the discharge t-set 9, and it is possible to realize high-precision divided packaging. Further, by increasing the supply amount every time the cumulative rotation angle RAac reaches the set angle RAs, it is possible to shorten the time from the powder supply device 8A to the outer peripheral groove 1 of the disk 7A to cause the powder to fall.

As described above, in order to make the accumulation amount increase position not to be repeated (as far as possible in the circumferential direction of the outer circumferential groove 10), it is necessary to make the supply rotation position when the cumulative rotation angle reaches the set degree RAs is not repeated (as far as possible to the outer circumferential groove 10) The direction of the week is scattered). In order to achieve this, the setting of various setting angles RAs is considered. For example, in the present embodiment, the set angle is an angle which is divisible by a predetermined 360 degrees. Table 1 below shows the set angle RAs of the present embodiment. [Table 1] Level ~ Set Angle RAs (degrees) Level 1 415 Level 2 393 Level 3 327 - Level 4 305 -^ Level 5 ------ 289 15 200819205 In Table 1 'Special Level 1 to Level 5 Indicates that the variation per unit time that increases the vibration intensity with respect to the increase in the cumulative rotation angle RAac is different. Usually, the rotational speed of the disk 7A is about 28 revolutions per minute, but since the set angle RAs value of the level 1 is 415 degrees, the cumulative rotation angle RAac of 415 degrees 5 is detected to increase the vibration value, due to the set angle of the level 5 The RAs value is 289 degrees, so the cumulative rotation angle RAac of 289 degrees is detected to increase the vibration value. That is, comparing the two, since the cumulative rotation angle interval of the honor level is long, the time span of the vibration change is also lengthened, and since the cumulative rotation angle ra ac of the level 5 is short, the time m span is also short. The time interval for controlling the vibration is also shorter than the level i. That is, the increase in the vibration intensity with respect to the increase in the cumulative rotation angle in the order from level 5 to level 1 becomes faster. The setting angles from level i to level 5 are 415 degrees, 393 degrees, 327 degrees, 3 degrees 5 degrees, and 289 degrees, and: 疋 When setting the natural multiple times, it is not repeated as much as possible on the outer circumference groove 1〇. The set angle RAs is not limited to the angle of Table 1, and the level i to level 5 can also be Example 2 • 480 degrees, 420 degrees, 390 degrees, 330 degrees, and 300 degrees. - In the present embodiment, the vibration intensity is increased every time the relationship of the following formula (1) is established. [Equation 1] 2〇RA^c = NxRAs (1) N ··Natural number In the eighth diagram A, P0 represents the supply position at the start of rotation of the disc 8A 'from pi to mo indicates level 1 (set angle theory is At the time of 415 degrees), 16 200819205 changes in the supply position of the respective set angles from N = 1 to N = 2 G. Similarly, in Fig. 8B, the change in the supply position of each set angle RAs from N = 1 aN = 2 时 when ρι to 2 〇 indicates the level 5 (the set angle RAs is 289 degrees). The ninth graph shows the relative value of the vibration intensity with respect to the level i (the set angle RAs is 415 degrees), 5 and 5 (the set angle RAs is 289 degrees), and the cumulative rotation angle RAac reaches the set angle RAs of N=5. Regarding 10 level 1 and level 5, the vibration intensity is increased every certain interval (with the symbol §). The level 5 is greater than the level 丨 with respect to the ratio of the cumulative rotation angle at which the ascending vibration intensity increases. The tenth graph shows the increase in the cumulative rotation angle RAac from the level 丨 to the level 5 and the increase in the output. As shown in the tenth figure, the initial value of the vibration intensity is set to be in the order of k level 5 to level 1. Further, in the tenth diagram, the symbol indicates the upper limit value of the vibration intensity. The eleventh diagram shows the relationship between the increase in the cumulative rotation angle with respect to the rank to the level 5 and the total amount (flow rate) of the powder supplied from the powder supply device 8A to the outer peripheral groove 1〇15. Φ PC60 receives the weight data of the dispensed drug from the monitoring system 77, and according to which one of the level 1 to level 5 is selected, the control device 72 performs the supply of the powder to the powder supply device 8 at the level determined by ^. also may. This day, as shown in Table 2 below, PC60 stores the flow coefficient μ (the index of a certain vibration necessary to carry the powder) and the relationship between the weight and the grade determined by the type of the drug. 17 200819205 [Table 2] Flow coefficient weight 1 Weight 2 Weight 3 Weight 4 Weight 5 0g or more 5g or less exceeds 5g 10g or less exceeds 10g 30g or less exceeds 30g i〇〇g or less exceeds 100g 1 (weak) Level 1 Level 1 Level 1 Level 2 Level 3 2 (slightly weak) Level 1 Level 1 Level 2 Special Level 3 Level 4 3 (Normal) Level 2 Level 2 Level 3 Level 4 Level 5 4 (Slightly Strong) Level 2 Level 3 Level 4 Level 5 Level 5 5 (Strong) Level 3 Level 4 Level 5 Level 5 Level 5 The heavier the weight, and the larger the flow coefficient (the less likely the loose drug is to flow), the higher the level is set to a larger value. The flow coefficient indicates that it is necessary to apply five strong vibrations as the value increases. For example, when the weight is 1 (0 g or more and 5 g or less) and the flow count is "1", the level 1 is selected. On the other hand, when the weight is 5 (more than 10 g) and the flow count is "5", the level 5 is selected. . When the type of the drug is unknown, the flow coefficient uses level 1 indicating the weakest vibration. In addition, the weakest flow coefficient is used when a plurality of agents are mixed. Also, when there is no weight data, ίο uses a weight corresponding to the minimum amount of 1. The set angle RAs can be manually input through the operation panel 16. The control unit 72 compares the set angle RAs newly input by the operation panel 16 with the set angle RAs that has been input. If the newly input set angle RAs is overlapped with the input set angle RAs, the control unit 72 prohibits the set angle RAs of the new input is from being input to the storage unit 73. Further, the control device 72 may not only prohibit the input, but may display a candidate for the set angle RAs that cannot be input and can be input on the operation panel 16. 18 200819205 The control device 72 detects the supply of the powder from the powder supply device 8 to the outer circumferential groove 10 by the following procedure '. For example, (4) When a tablet such as a sugar-coated tablet is broken and then packaged, in the case where the shell is easy to flow and the music is not easy to flow, there is a concern that the shell is detected by the sensation of the genus 60, although it is The medicine itself does not have a state in which the k-slot 22 is supplied to the outer peripheral groove, but it is judged that the powder medicine is supplied from the powder supply device 8A to the outer circumferential groove 10. In order to avoid the above-mentioned judgment error, the powder drop sensor 50 will continue to be in an open state for a predetermined sufficient time (for example, 2 seconds) (detecting a state in which the medicine falls from the medicine tank) 1〇, and it is judged as a powder medicine. The supply begins. In addition, as shown in the twelfth figure, when the state of the sensory person 50 has changed under the political Ι 洛, as shown by the symbol b, if there is a closed state of 40 ms or more between the open state and the open state. , then resets the continuation time of the open sorrow. Then, as in the time t, it is determined that the supply of the medicine is started when the on state continues for 2 seconds. I5 However, since there is a case where the powder is intermittently flowed at the start of the supply depending on the type of the powder, the treatment is limited to 60 seconds after the start of the distribution, and then the sensor 50 is detected to some extent if the powder falls. The time (for example, 40 ms) is continuously on, and it is judged that the supply of the medicine starts. (Second Embodiment) 2〇 In the second embodiment, only the method of determining the set angle RAs is different from that of the first embodiment. In other words, in the present embodiment, the angle RAsta is added to the reference set angle RAsta which is a predetermined angle, and the offset value RAc of various values is added as the set angle RAs. The following equation (2) shows the relationship between the set angle RAs, the reference setting angle, and the offset value RAc. Further, '19 200819205 may be a value obtained by subtracting the offset value RAc from the reference setting angle RAsta as the set angle RAs. RAs_RAsta+RAc An example of setting the angle RAs will be described below. Further, the increase in the vibration intensity 5 is performed every predetermined amount (symbol δ) as in the first embodiment. The reference setting angles Rasta of the ranks 1 to 5 are 3, 330, 390, 420, and 510 degrees, respectively.
