Description

TECHNICAL FIELD The present invention relates to a powdered medicine scraping device and a powdered medicine packaging device for scraping out a predetermined amount of powdered medicine contained in a groove of a powdered medicine containing member, and more particularly to an automatic centering mechanism for the powdered medicine scraping member.

Conventionally, powdered medicine packaging apparatuses uniformly supply powdered medicine to a powdered medicine containing member (also referred to as an R disc or a distribution plate) having an annular groove with an arcuate cross section, and rotate a rotating plate having a scraping plate to feed the powdered medicine in the annular groove. A powder medicine scraping device is provided for dispensing and scraping out one package at a time (see Patent Documents 1 and 2).

In such a powdered medicine scraping device, if the outer peripheral surface of the rotating plate of the powdered medicine scraping member is not in close contact with the annular groove of the powdered medicine containing member, the powdered medicine will not contact the rotating plate when the powdered medicine is scraped out or when the powdered medicine containing member is rotated. Since it leaks from the gaps between the annular grooves, the amount of packaging varies, and scrape leakage occurs. For this reason, alignment work (alignment work) is performed to align the center of rotation of the rotating plate of the powdered medicine scraping member with the center of curvature of the annular groove of the powdered medicine containing member for each powdered medicine dispensing and packaging device. In practice, the center of rotation of the rotary plate is set lower than the center of curvature of the annular groove, and silicon rubber provided on the outer periphery of the rotary plate is pressed against the annular groove.

However, the powdered drug containing member has a structure in which the annular groove rotates, and the rotating plate is supported by the rotating shaft at the tip of the arm so as to be rotatable, and also has a structure that moves up and down with respect to the annular groove of the powdered drug containing member. Therefore, the alignment work is difficult, time-consuming, and requires a great deal of labor. In addition, due to differences in each powdered drug packaging device, the adjustment allowance can only be used for devices that have been centered. Furthermore, if the silicon rubber of the rotating plate is pressed too much against the annular groove, the silicon rubber and the annular groove will wear out, generating abrasion powder. I had to pay and adjust the amount of pressure.

The elastic edges 28 such as are integrated by heat sealing. A triangular mounting hole 23a is formed in the central portion of the rotary plate 23, and long positioning holes 23b are formed on both sides of the mounting hole 23a. A scraping plate 29 is integrally provided on the surface of the rotating plate 23 . The scraping plate 29 is formed by bending a plate-like body such as stainless steel to form a scraping portion 29a and a partition portion 29b. An elastic piece 29c made of silicon or the like is integrated with the tip of the raking portion 29a. A portion of the outer edge of the partition portion 29b is formed in an arc shape along the annular groove 8a of the powdered medicine containing member 8. As shown in FIG.

As shown in FIG. 6(b), the mounting substrate 24 is made of a disc made of stainless steel. Four screw through holes 24c are provided at separated positions. A triangular pyramid-shaped protrusion 30 that engages with the mounting hole 23a of the rotating plate 23 is attached to the rotating plate side surface of the mounting substrate 24 with a nut 31 by inserting the male screw 30a into the screw through hole 24b. . At symmetrical positions on both sides of the protruding portion 30, conical mounting pins 32 that engage with the positioning holes 23b of the rotary plate 23 are attached. The mounting pin 32 is radially slidably accommodated in a notch 24 d formed at a position 180 degrees apart from the outer peripheral edge of the mounting board 24 , and biased radially outward by a spring 33 . The notch 24 d of the mounting board 24 is covered with a stop plate 35 attached with screws 34 . A positioning plate 36 having positioning protrusions 36a is attached to the stopping plate 35 so as to overlap it.

The driven member 25 is composed of a disk portion 25a and a cylindrical portion 25b projecting from the outer peripheral edge of the disk portion 25a toward the rotating plate, and is large enough to engage with the inside of the positioning rib 24a and the positioning projection 36a of the mounting substrate 24. It has a A central hole 25c through which the rotary shaft 21 passes is formed in the center of the disk portion 25a. As shown in FIG. 5, four bosses 25d protrude from the rotating plate side of the disk portion 25a at positions spaced apart from the center by a predetermined distance. Four screw holes 25e are formed at corresponding positions. The driving member 22 is accommodated inside the cylindrical portion 25b. Four protrusions 25f are provided inside the cylindrical portion 25b, and spring accommodating recesses 25g are formed in the respective protrusions 25f at positions facing the respective spring receiving holes 22f of the driving member 22. As shown in FIG.

The elastic member 26 consists of a coil spring, one end of which is inserted into and supported by the spring receiving hole 22f of the drive member 22, and the other end of which is inserted and supported by the spring receiving recess 25g of the driven member 25 via a flanged pin 37, and is compressed. installed in the state As shown in FIG. 7, the elastic member 26 can expand and contract in the tangential direction of a virtual circle C centered on the rotation shaft 21. As shown in FIG. The expansion and contraction direction of the elastic member 26 may deviate from the tangential direction to some extent, as long as it is different from the radial direction.

The mounting board 24 and the driven member 25 are integrally fixed by inserting the fixing screw 38 into the screw through hole 24c of the mounting board 24 and screwing it into the screw hole 25e of the driven member 25 . The rotating plate 23 is attached by engaging the triangular pyramid-shaped protrusion 30 of the mounting board 24 with the mounting hole 23a and engaging the mounting pin 32 of the mounting board 24 with the positioning hole 23b. As a result, the rotating plate 23, the mounting substrate 24, and the driven member 25 can rotate integrally. Further, as shown in FIG. 8, the rotating shaft side member and the rotating plate side member are rendered immovable in the axial direction by sandwiching the driving member 22 between the mounting substrate 24 and the driven member 25 .

Returning to FIG. 2, the packaging unit 4 receives the powdered medicine scraped out from the powdered medicine scraping unit 3 into the wrapping paper 41 that is drawn out from the paper roll 40 and folded in two through the packaging hopper 42. Heater rollers 43a, 43b is configured to seal and discharge one package at a time.

Next, the operation of the powder drug scooping device 1 having the above configuration will be described.

First, in a state in which the powdered medicine is evenly supplied to the annular groove 8a of the powdered medicine containing member 8, the arm 12 is lowered by the elevating motor 15 of the powdered medicine scraping device 9 to press the rotating plate 23 against the annular groove 8a, thereby circularly Separate the powdered medicine in the groove 8a. Subsequently, the powdered medicine containing member 8 is rotated by a predetermined angle, and the powdered medicine is scraped by the rotating plate 23 .

Next, when the rotating shaft 21 is driven by the rotating motor 14 of the powdered drug scraping device 9 , the driving member 22 rotates integrally with the rotating shaft 21 . As shown in FIG. 7, of the two elastic members 26 positioned on both sides of the projecting portion 22b of the drive member 22, the elastic member 26 on the front side in the rotational direction is compressed and pushes the projecting portion 25f of the driven member 25, The elastic member 26 on the rear side is pulled to draw the protrusion 25f of the driven member 25 closer. As a result, the rotational force of the driving member 22 is transmitted to the driven member 25 via the elastic member 26, so that the driven member 25 rotates. The rotation of the driven member 25 causes the mounting substrate 24 and the rotating plate 23 to rotate.

When the rotating plate 23 rotates, the powdered medicine between the rotating plate 23 and the partition portion 29b of the scraping plate 29 is scraped out by the scraping portion 29a from the annular groove 8a of the powdered medicine accommodating member 8 into the packaging hopper 42, and is then sent to the packaging portion 4. It is packed in one package.

If the center of curvature of the cross-section of the annular groove 8a of the powdered medicine containing member 8 does not coincide with the center of the rotating plate 23, gaps or uneven contact may occur between the rotating plate 23 and the annular groove 8a, leaving the powdered medicine unscraped. Problems such as a decrease in rotational force of the rotating plate 23 due to pressure contact of the rotating plate 23 with the annular groove 8a occur. Therefore, before operating the powdered medicine scraping device 1, the positions of the base 11 of the powdered medicine scraping device 9 and the powdered medicine containing member 8 are adjusted so that the center of rotation of the rotary plate 23 coincides with the center of curvature of the annular groove 8a. centering work is required. In this embodiment, since the elastic member 26 is mounted between the shaft-side member and the plate-side member, the center of rotation of the rotating plate 23 does not need to be precisely aligned with the center of curvature of the annular groove 8a. , the center of rotation of the rotary plate 23 is automatically aligned with the center of curvature of the annular groove 8a.

That is, as shown in FIG. 7, when the rotation center of the rotating plate 23 and the driven member 25, which is a rotating plate side member, deviates from the center of curvature of the annular groove 8a, while the rotating plate 23 rotates, the annular When the rotating plate 23 contacts the groove 8a, the elastic member 26 is deformed, and the driven member 25 that rotates together with the rotating plate 23 elastically moves with respect to the rotating shaft 21, so that the center of the rotating plate 23 forms the annular groove. It is aligned with the center of curvature of 8a. In this case, the rotating plate 23 rotates eccentrically with respect to the rotating shaft 21 . Since the center of the rotating plate 23 is automatically aligned with the center of curvature of the annular groove 8a, it is possible to simplify the work of aligning the annular groove 8a of the powdered medicine containing member 8 and the powdered medicine scraping device 9, and to separate the powdered medicine. There is no variation in the amount of packaging and no scraping leftovers. In this embodiment, since the elastic member 26 is arranged in the tangential direction of the virtual circle C centered on the rotating shaft 21 , the rotating plate 23 follows the rotating shaft 21 well.

The elastic member 65 is made of an annular rubber material, has an inner peripheral surface fixed to the outer peripheral surface of the annular projection 62 c of the second driving member 62 with an adhesive or the like, and has an outer peripheral surface attached to the inner peripheral surface of the driven member 64 . It is attached by being fixed with an adhesive or the like.

In the rotating member 13 b of the third embodiment, the first driving member 62 and the second driving member 62 rotate together with the rotating shaft 21 . When the second driving member 62 rotates, the elastic member 65 is displaced in the circumferential direction with respect to the driven member 64. As a result, the rotational force of the second driving member 62 is transmitted to the driven member 64 via the elastic member 65, and the mounting substrate is mounted. 24 and rotating plate 23 rotate.

Also in the rotating member 13b of the third embodiment, as in the first embodiment, as shown in FIG. 15, the rotation center of the mounting substrate 24, which is the rotating plate side member, is deviated from the center of curvature of the annular groove 8a. In this case, the elastic member 65 is deformed while the rotating plate 23 rotates, and the mounting substrate 24 rotating integrally with the rotating plate 23 elastically moves with respect to the rotating shaft 21, so that the center of the rotating plate 23 is annular. It is aligned with the center of curvature of the groove 8a. As a result, it is possible to simplify the work of aligning the annular groove 8a of the powdered medicine containing member 8 with the powdered medicine scraping device 9, and eliminate variations in the amount of packaging and scraping leftovers.

The present invention is not limited to the above-described embodiments, and variations and modifications are possible without changing the gist of the invention. For example, the elastic member may be provided between the rotating shaft side member and the rotating plate side member, and its mounting position can be changed arbitrarily. However, it may be a leaf spring or a torsion spring. In particular, the elastic member may be provided directly between the rotating plate and the rotating shaft instead of between the rotating shaft side member and the rotating plate side member. For example, an elastic member made of a coil spring may be arranged in the axial direction, one end of which is fixed to the rotating shaft, and the other end of which is fixed to the rotating plate.
