Supply equipmentWhereIt is disclosed.
[0008]
  Further, with the downsizing of the machine, conventionally, the scraping mechanism and the packaging hopper are installed on the outer peripheral portion of the R distribution tray 5, which hinders the downsizing of the machine.
[0009]
[Problems to be solved by the invention]
  By the way, in order to manufacture a powder distribution tray as disclosed in Japanese Patent Laid-Open No. 8-85502 at a low price, it is desirable to press the powder distribution tray, and since it comes into contact with the powder, durability and cleanliness are maintained. Also in the above, what uses stainless steel is desirable.
[0010]
  In addition, the powder distribution tray requires a high degree of accuracy. In particular, the R-shaped hollow diameter of the powder distribution plate, the accuracy of the rotation axis when the powder distribution plate is rotated, and the rotation axis of the powder distribution plate Shaking, noise and low vibration, deflection and twisting of the powder distribution tray are required.
[0011]
  In addition, when the R distribution tray is rotated at a high speed, a part of the powder scattered during distribution from the feeder is blown away by the rotational centrifugal force.Granules etc.Contact portion of the roller where powdered powder contacts the rotating support ring and the rotating support ringBiteLook intoresult,Sudden noise generation and rattling of the R distribution tray, ResistantIt is required that these problems do not occur because of the decline in durability.
[0012]
  Furthermore, the problem of machine downsizing is one of the problems.
[0013]
  In the present invention, the powder distribution tray is cheap and the powder distribution tray can be pressed to maintain high accuracy.UnaKeeping the shape, and rotating the powder distribution tray, when the powder distribution tray is actually rotated, the R-shaped recess diameter axis of the powder distribution tray, the accuracy of the rotation axis when rotating the powder distribution tray, and the rotation of the powder distribution tray It can be easily assembled and adjusted for the required accuracy such as noise and vibration reduction when rotating the shaft or rotating the powder distribution tray at high speed, and it will scatter during distribution from the feeder. A part of the powder is blown off by the rotational centrifugal force and is engaged in the rotation support ring and the contact portion of the roller that is in contact with the rotation support ring.
[0014]
[Means for Solving the Problems]
  In order to solve the above problems, the present invention provides:In a powder distribution device that allows a powdered powder accumulated in the hollow portion to be scraped by a scraping device one by one by rotating a donut-shaped powder distribution tray having a hollow portion having an arcuate cross section at a predetermined pitch angle. The outer periphery side edge of the powder distribution tray is formed higher than the inner periphery side edge.The configuration.
  Moreover, the collar part was provided in the outer peripheral side edge of the said powder distribution tray, and it was set as the structure by which the said powder distribution tray was rotatably supported through the said collar part.
[0015]
  Thereby, the distribution tray which can rotate the powder distribution tray at high speed can be manufactured at a low price while maintaining high accuracy by press working.
[0016]
  Also, the flange provided outside the outer peripheral side edge of the R-shaped depression and the lowest point of the R-shaped depression of the powder distribution tray are concentric with the rotation axis supported by the rotation support ring. The rotary support ring of the powder distribution tray is rotatably supported along the collar.
[0017]
  By this, when the powder distribution dish is actually rotated, the accuracy of the R-shaped hollow portion diameter of the powder distribution dish and the rotation axis when the powder distribution dish is rotated and the rotation of the powder distribution dish It is possible to solve problems such as easy assembly and adjustment with respect to required accuracy such as reduction of noise and vibration when rotating the shaft or the powder distribution tray at high speed.
[0018]
  Furthermore,The contact portion between the support ring and the roller is provided at a position where powdered powder scattered during rotation of the powdered distribution tray cannot be caught..
[0019]
  As a result, while distributing the powder from the feeder, even if the R distribution tray 5 is rotated at a speed of about 60 revolutions per minute, the powder such as granules scattered by the centrifugal force of the R distribution tray is in contact with the rotating support ring. Therefore, noise and rotation shakiness can be prevented.

[0033]
OutsideOn the outer periphery of the peripheral edge 5c,R distribution tray55d for holding the support ring 6 for rotatingButR distribution tray5And is integrally formed.
[0034]
  Figure 6 shows the feeder1It is a figure which shows arrangement | positioning.
[0035]
  The trough shown here3As shown in FIG. 7, the tip portion is lowered in two stages, and the tip portion of the trough 3 is further divided into two guide grooves 3a.,3b.
[0036]
  These two guide grooves 3a,3b is disposed at the inner and outer peripheral positions with the lowermost point 5b of the R-shaped depression part in between.ing. ThisPowder falling from the tip of the trough 3 is guided groove 3a.,Many fall from 3b, guide groove 3a to R distribution tray 5,Each of the powders that fall from 3b bounces in the direction of the lowest point 5b of the R-shaped depression.JustDeposited at the position of the lowest point 5b of the R-shaped depression.

[0040]
  The scraping device 7 is retracted upward during distribution, and distribution ends.And descendingLower R distribution pan5When the scraping device 7 makes one rotation, the R distribution tray5The powder is scraped off in the inner diameter direction.
[0041]
  When these dispensing and dividing operations are completed, the cleaner 45 with a rotating brush shown in FIG.TheActuate to clean the surface of the R-shaped depression of the R distribution tray 5 and wait for the next prescription.
[0042]
  The operation of the scraping device 7 is performed as follows.
[0043]
  Scraping device 7 as shown in FIG.IsThe range in which the powder deposited on the R distribution tray 5 is cut out by the disk 12 and the R distribution tray 5 is rotated and sent.Powdered medicineIs scraped to the disk 12 and then guided by the rotation of the scraping device 7Board13 is the powder deposited on the R distribution tray 5partition,A scraping plate 14 provided between the disk 12 and the guide plate 13 is scraped off from the R distribution tray 5, and these are driven by a motor 15.
[0044]
  As shown in FIGS. 8B and 8C, the tip of the scraping plate 14 moves along the R inner surface according to the rotation of the scraping device 7 while contacting the inner surface of the R distribution tray 5., Fig. 8 (as shown in c)Scraper 14When a cut is made at the tip, the repelling of the rubber material of the scraper plate is suppressed when separating from the R distribution tray 5, and the granular powder is less likely to jump.
[0045]
  FIGS. 9A and 9B are side views of the scraping device.
[0046]
  Scraping device7Disc12The rotation does not rotate at a constant speed, but rotates at a set speed within a predetermined range.
[0047]
  As shown in Fig. 9 (b), the range during the scraping operation is divided as follows:Yes.At the position of the inner peripheral edge 5a of the R distribution tray 5The scraping device 7Stopped or slowed to minimum speed.
[0048]
  After passing through the position of the inner peripheral edge 5a of the R distribution tray 5, the rotational speed is accelerated for a while, and the rotational axis x rotates at a substantially constant speed from a certain position.To do.From the end of accelerationOutsideThe range of the peripheral edge 5c is set as the speed adjustment section.
[0049]
  In this speed adjustment section, the scraper 14 is used as a reference for rotation of the R distribution tray 5.OutsideRather than being based on the fact that the peripheral edge 5c has been reached, the point is whether the tip of the guide plate 13 has reached.is there.For example, when the divided feeding angle of the R distribution tray 5 is small, the tip of the guide plate 13 is the R distribution tray.5 outer edgeThe divided feed angle reaches the next stop point earlier than it reaches the position 5c.
[0050]
  For this reason, it is not necessary to decelerate in the rotation axis x speed adjustment section. However, if the set number of packages decreases, the divided feed angle of the R distribution tray 5 increases correspondingly, so the rotation axis x speed adjustment section. When the guide plate 13 is rotated at a constant speed, the tip of the guide plate 13 is moved to the R distribution pan earlier than the divided feed angle reaches the next stop point.5 outer edgeWhen the rotation axis x is rotated as it is, the guide plate 13 comes into contact with the powder powder deposited when the rotary shaft x is rotated as it is, and the R distribution tray 5 is still fed and deposited on the R distribution tray 5 necessary for the division. The powder range cannot be taken in between the disk 12 and the guide plate 13, resulting in a packaging error.
[0051]
  For this reason, time data corresponding to increase / decrease of the number of packages and the feed angle of the R distribution tray 5 is stored, and the tip of the guide plate 13 is placed on the R distribution tray.5 outer edgeWhen it is predicted that the time to reach the position 5c is earlier than the stored time, the rotational speed of the rotary shaft x is controlled to be decelerated in the speed adjustment section.
[0052]
  As shown in FIG. 1, above the R distribution tray 5, a tablet dividing machine for manually dividing and packaging tablets.37Is provided, and a shutter that drops onto the packaging hopper 838Tablet shoot with39Are provided corresponding to the width of the divider.
[0053]
  Tablet splitting machine37Is a container arranged in a small grid, and a bottom plate shutter (not shown) is also provided on the bottom of each bowl.
[0054]
  This bottom plate shutter is a tablet divider37Because it moves while touching the bottom with respect to the direction of movement, the chute39Tablet opening machine when reaching the opening of37The bottom plate shutter releases naturally and shoots the tablets in the container39It has come to drop. This shoot39The opening of the tablet divider37Tablet splitting machine37The tablet dividing machine is provided with a step-like slit at a pitch obtained by dividing one wrinkle in the transfer direction by the number of wrinkles provided in the width direction.37The tablet dividing machine37The tablet dividing machine in order from the front corner to the width direction is transported at a pitch divided by the number of wrinkles provided in the width direction.37The bottom plate shutter is released.
[0055]
  shoot39Shutter at the exit38Operates at the timing associated with a series of these operations.
[0056]
  Figure 14 shows a conventional scrapingDevice 7And R distribution tray5Driving and packaging hopper8Shows the arrangement of etc.TheScraping device7Lifting arm to raise and lower the disk 127aThe rotary shaft and the packaging hopper 8 are provided on the outside of the R distribution tray 5, and the R distribution tray5 isDriven by the R distribution tray drive motor 16, the feeder 1 is arranged outside the R distribution tray 5.IsWhen the powder is put into the charging hopper 2, the powder is supplied to the R portion of the R distribution tray 5 through the trough 3.
[0057]
  In the case of the device for scraping and packaging the powder in the center direction of the R distribution tray 5 shown in FIG. 10, the rotation drive of the R distribution tray 5 cannot be held at the center as shown in FIG. The support ring 6 is provided on the outer periphery of the support ring 6.roller17 supports the rotation.
[0058]
  The support of the R distribution tray 5 plays an important role in such a device, and if there is a problem with the means of rotation support, the R distribution tray 5Of 5Due to the vibration generated during rotation, the powdered powder is distributed on the concentric circle at the lowest point 5b of the R-shaped depression during distribution.FromAs a result, a phenomenon in which the powder is meandered or distributed eccentrically, or a powder concentrates on a part of the circumference, which directly affects the division accuracy.
[0059]
  About this rotation supportproblemAs a technology to solve the problem5It can be easily solved by supporting it with the rotation center axis of the R distribution tray as in the present invention.5When scraping out powder in the direction of the rotation center axis, at least the R distribution dish5R distribution tray outside the inner peripheral edge 5a5Will be subject to the restrictions to support the rotation of the R distribution tray5R distribution tray outside the inner peripheral edge 5a5When the rotation support is performed, the R-distribution dish is obtained from the relationship between the R-shaped depression bottom point 5b and the rotation support means.5It is difficult to adjust the concentricity of the rotating shaft during assembly, and the support ring 6 is attached to the R distribution tray.5The more you move away from the rotating shaft in the outer circumferential direction, the more R distribution tray5There is a relation that the degree of difficulty of adjusting the concentricity of the rotating shaft during assembly becomes high.
[0060]
  Conventionally, R distribution tray5In the case of rotating at 30 revolutions per minute5It is also possible to support the rotation support part of the rotation part away from the rotation axis to a certain extent in the outer circumferential direction.. But,In the case of the present invention rotating at 60 revolutions per minute, the R distribution tray5The accuracy and shape of pressing must be rigorously required, and the support structure must be positioned at a high peripheral speed.rollerThere are conditions such as supporting with 17, etc.rollerIf the arrangement of 17 is not devised, the scattered powder is scattered with the support ring 6roller17 includes a condition that bites between 17 and generates noise that could not be considered in the past. (Conventionally, R distribution tray5SupportIn structure, The rotation speed is lower than the falling position of the powder distribution tray,rollerEven if you don't care much about the arrangement of the powder,rollerThe problem of biting in between does not occur. )
[0061]
  From these, the support ring 6 androllerBetween 17PowderBiteWhen,In order to vibrate the R distribution tray 5, the powder powder is distributed on the concentric circle at the lowest point 5 b of the R-shaped depression during distribution.FromThis causes problems such as meandering, eccentric distribution, or concentration of powder on a part of the circumference.TheIn the present invention, as shown in FIG.roller17 is located below the position of the ridge 5d of the R distribution tray 5 and in the substantially inner radial direction of the outer diameter of the ridge 5d, so that the powder is being distributed. When the splashes, the support ring 6 androllerIt does not bite into the contact portion with 17.
[0062]
  Also, the support ring 6rollerWhen the contact portion with 17 is positioned below the position of the ridge 5d of the R distribution tray 5 and in a position substantially in the outer radial direction of the outer diameter of the ridge 5d, the powder scattered from the R distribution tray 5 under conditions such as centrifugal force In the rare case where it is provided inside the flying parabolic range, the support ring 6 androllerHowever, this is not a problem, and even in such a case, the support ring 6rollerIf the powder powder sticking to the support ring 6 is removed by pinching the contact portion with the brush 17 as shown in FIG. 6, continuous vibration can be generated.
[0063]
  However, the support ring 6roller17 is the same or above the position of the ridge 5d of the R distribution tray 5, and the position of the outer peripheral diameter of the ridge 5d in the substantially outer radial direction, or under conditions such as centrifugal force from the R distribution tray 5, When it is provided outside the flying parabolic range of the scattered powder,rollerSince the powder will frequently bite into the contact portion with 17, even if the support ring 6rollerEven if the powder that is stuck to the support ring 6 is removed by sandwiching the contact portion with the brush member 36 as shown in FIG. 6, the powder that sticks without being removed in a short time accumulates, and continuous vibration occurs. This is not preferable.
[0064]
  (A), (b), and (c) of FIG.rollerIt is a figure which shows the support form of 17.
[0065]
  The support ring 6 of FIG.rollerThe support form 17 presses the inner diameter side of the support ring 6 downward in the outer peripheral direction.roller17 and the support ring 6Roller installed17And byIt is designed to support from two directions, with a support ring 6 on the back side of the R distribution tray 5 androller17Is arranged.

  The support ring 6 of FIG.rollerThe support form 17 presses the outer diameter side of the support ring 6 downward in the inner circumferential direction.roller17 and the support ring 6Roller installed17And byThe support ring guide 6a is supported from two directions and extends from the support ring toward the upper side from the outer side of the flange 5d provided on the outer peripheral portion of the R distribution tray 5.
[0067]
  For this reason, the powder scattered from the surface of the R distribution tray 5 is less likely to be scattered to the outer peripheral side of the R distribution tray 5 by the support ring guide 6a.rollerAlmost no powder is sandwiched between 17.
[0068]
  Here, the shape of the support ring guide 6a is a support ring extending upward,roller17 may be a support ring guide 6a that extends in the outer peripheral direction so as to cover the upper portion of 17 and, instead of the support ring guide 6a, by a flange 5d provided on the outer peripheral portion of the R distribution tray 5,rollerYou may make it cover on 17 upper part.
[0069]
  The support ring 6 of FIG.rollerThe support form 17 presses the outer diameter side of the support ring 6 downward in the inner circumferential direction.roller17 and the support ring 6Roller installed17And bySupporting from two directions, a gap is provided between the flange 5d and the support ring 6 on the back surface of the flange 5d provided on the outer peripheral portion of the R distribution tray 5, and this gap is the starting point.roller17 by a cover member 18 provided so as to cover above 17roller17 covers the periphery that does not contact the support ring 6.
[0070]
  thislikeBy the cover member 18roller17 is covered, so it happens that the support ring 6 androllerAlmost no powder is sandwiched between 17.
[0071]
  Also,Roller 17The contact surface may be made of a material such as resin, and a soft material that can absorb vibrations may be fixed to the support ring.rollerBy using a resin or rubber-related material for the surface material 17, it is possible to cope with an increase in the speed of the R distribution tray 5.
[0072]
  Furthermore,roller17 can be as large as possible,Roller 17The rotation speed of the machine is reduced, and durability, noise, and vibration can be suppressed.
[0073]
  It is disclosed hereFIG.(A), (b), and (c) are the means shown in the implementation, and were scattered by the centrifugal force of the R-distribution dish on the rotation support ring of the powder distribution dish and the contact part of the roller that contacts the rotation support ring.

  FIG. 12 shows a form in which the form for attaching the R distribution tray 5 is different.
[0075]
  The eaves 5d of the R distribution tray 5 raised here does not have a screw hole for tightening with the support ring 6, and the eaves 5d of the R distribution tray 5 are bent in an annular shape downward from the horizontal line.
[0076]
  By bending the flange 5d downward in this way, the bending strength of the R distribution tray 5 improves as the bending angle becomes tighter from the horizontal direction to the vertical direction.6Difficulties arise in the structure to be attached to

  In addition, a flange provided outside the outer diameter edge of the R-shaped depression, a rotation support ring is provided along the flange on the concentric axis with the rotation axis of the powder distribution tray, and the rotation support ring includes the flange While being fixed, it was set as the structure which supports the rotation support ring of the said powder distribution tray rotatably.
[0091]
  By this, when the powder distribution dish is actually rotated, the accuracy of the R-shaped hollow portion diameter of the powder distribution dish and the rotation axis when the powder distribution dish is rotated and the rotation of the powder distribution dish It is possible to solve problems such as easy assembly and adjustment with respect to required accuracy such as reduction of noise and vibration when rotating the shaft or the powder distribution tray at high speed.
  In addition, a guide groove is provided at the tip of the trough that supplies powder to the powder distribution tray, and the powder is scattered from the powder distribution tray because the powder is supplied from the guide groove while vibrating the trough. There is no.
  Since the guide groove is arranged on the inner and outer peripheral sides with the lowest point of the depression part of the powder distribution tray, the powder falling from the guide groove jumps in the direction of the lowest point of the depression part, As a result, the powder is not scattered from the powder distribution tray.
  Since the tip of the trough is lowered in two stages and the drop height of the powder onto the powder distribution tray is suppressed, the drug becomes difficult to jump on the powder distribution tray, and the powder can be dispersed and deposited.
