Japanese Examined Patent Publication No. 53-22345

  Such a medicine packaging machine is small and has a small installation space, is easy to handle, and is inexpensive. Therefore, it is widely used in small and medium-sized hospitals, clinics, and clinics. .

  In such a conventional small medicine packaging machine, in order to divide the powder according to the prescription in the powder dividing unit, first, a total amount of powder according to the number of the medicines to be dispensed is put into an elongated dividing basket having a V-shaped cross section. After that, the surface is leveled so that the powder is uniform in the divided cage. After that, when the lid opening / closing mechanism is operated to open the opening / closing plate, the powder put in the split basket falls into a plurality of powder storage bodies located below and is divided into the number according to the prescription. In this way, in order to divide the powder charged in the divided basket, in order to match the number of divided packages, the powder can be divided and measured in advance in a range corresponding to the number of powder storage bodies located immediately below the divided basket. Is set to

  The number of divisions (packaging) is set by dividing the length of the divided basket in the width direction and adding a scale. For example, the contents of the divided basket according to the number of packages such as 42 packs and 21 packs. A partition plate for setting the product is configured to be able to move in accordance with a scale set in advance in the divided cage. The setting of the measurement section according to the number of packages by such a partition plate is generally divided into 42 packages for a maximum of 14 days in order to package the whole number of packages as an integral multiple of 3 packages per day. However, as a special case, in the case of medication to a long-term user, a prescription for 30 days may be made.

  For this reason, it is required to package as 45 packages × 2 = 90 packages in order to rationally package special cases. Currently, there is a dividing bag with the maximum number of divisions per operation being 45. Is provided. However, in this type of sachet, the powder put in the split basket is manually leveled and split, so as described above, it is generally divided into 42 sachets for 3 days per day up to 14 days. Many wrapping operations are performed. For this reason, normally three packages are extraneous, and the input powder cannot be accurately packaged unless the partition plate is correctly aligned with the scale position corresponding to 42 packages. Therefore, it is necessary to pay close attention to the position setting of the partition plate, and there is a problem that it is easy to make an error and is inconvenient.

  This invention was made in order to eliminate such a problem, and it aims at providing the packaging machine provided with the function which can partition correctly the excessive part at the time of normal use in a powder division | segmentation dividing pot. Is.

In order to achieve the object, a packaging machine according to the present invention comprises:
A powder container for dividing accommodating the powder, a dispersion agent split squares to drop the powder was accepted by opening the opening and closing plate in the upper position of the powder container in the powder storage body, that is provided on the inside of the powder dividing squares In a packaging machine comprising a partition plate movable in the longitudinal direction of the powder dividing basket, and enclosing the powder in a bag by a predetermined amount,
Division regulation means for regulating movement of the partition plate is provided, and the division regulation means is configured to be capable of taking a first operation mode and a second operation mode, and the division regulation unit is configured to have the first regulation mode. When in the operation mode, the division restricting means prevents movement of the partition plate at a position corresponding to the normal maximum number of divisions, and when the division restricting means is in the second operation mode, the partition plate Movement is permitted up to a position corresponding to the maximum number of divisions of the special case greater than the normal maximum number of divisions .

  In the present invention, when the partition plate is moved toward one end in the longitudinal direction of the powder dividing rod, when the split regulating means is in the first operation mode, one end in the longitudinal direction of the powder dividing rod. When the dividing restricting means is prevented from moving before the dividing restricting means, and the dividing restricting means is in the second operation mode, the partition plate is allowed to move to one end in the longitudinal direction of the powder dividing split. It is preferable.

  In the above invention, the division restricting means includes a restricting piece, and when the dividing restricting means is in the first operation mode, the restricting piece comes into contact with the divider plate to move the divider plate. Is preferably prevented.

  Here, it is preferable that the restricting piece is disposed between an end plate on one end side of the powder dividing rod and the partition plate.

According to the present invention, when the partition plate is operated in the dividing basket as a preparation means for setting the number of divided powders, the division restricting means takes the first operation mode when setting the normal maximum number of divisions. If the partition plate is moved to the maximum normal packaging position, the partition plate cannot be moved further by the division restricting means, and the maximum number of packages (for example, 42 packages) can be automatically set. Thus, the packaging operation can be performed without being overdivided. On the other hand, when it becomes necessary to divide into a special maximum division number (for example, 45 pieces ) that is larger than the normal maximum division number , if the division regulation means takes the second operation mode, The plate can be moved to the extreme end position in the split basket, and can be divided into 45 packages for packaging. In this way, with a simple configuration, it is possible to accurately partition the surplus portion during normal use in the powder divided basket.

  Next, specific embodiments of the packaging machine according to the present invention will be described with reference to the drawings.

  FIG. 1 is an overall outline view of a packaging machine according to an embodiment of the present invention. In FIG. 2, the principal part expansion external appearance perspective view of the powder splitting basket in the packaging machine of this embodiment is shown, in FIG. 3, the principal part sectional view of the packaging machine of this embodiment is shown in FIG. FIG. 4B shows a front view of the division restricting means, and FIG. 4B shows a sectional view showing the operation mode.

  The medicine packaging machine shown in FIG. 1 has a box-shaped machine body 1, and a powder packaging unit 2 and a tablet packaging unit 6 (see FIG. 3) are provided inside the machine body 1, The powder / tablet dispensed sequentially from the powder packaging unit 2 and the tablet packaging unit 6 is sent out through a chute (not shown) and packaged by a wrapping paper in a packaging means (not shown). Has been. The powder packaging unit 2 is pivotally attached at one end around the endless belt 3 (see FIG. 3) so as to be adjacent to each other over almost a half circumference (for example, as known from JP-A-7-61402). The powder storage body 4 is arranged in such a manner that the powder fallen from a powder dividing basket, which will be described later, is divided and received, and the opening / closing lid 5 that is attached to the bottom and is always closed by the magnet 5a is provided directly on the chute (not shown). When opened sequentially at the top, the powder is put into the wrapping paper that moves from the chute to the packaging part.

  Further, the tablet dividing unit 6 has a tablet dividing board 7 in which a required number of tablet storage baskets 7a are arranged, intermittently moves toward the upper part of the chute, and sequentially opens and closes the opening / closing lid 7b provided at the bottom. A tablet is dropped onto the chute from inside the storage basket 7a and is put into a wrapping paper that moves from the chute to the packaging part. The supply of tablets to the tablet storage basket 7a can be visually selected with the same distribution just above the stop position of the tablet storage basket 7a on the lid 8 covering the upper surface of the machine body 1. 6A is provided.

  At the front position (operating side) of the upper surface of the lid 8 of the machine body 1, the powder dividing rod 10 is required to have a total length in the longitudinal direction corresponding to the arrangement of the powder container 4 of the powder packaging unit 2. It is arranged at a position directly above the powder packaging unit 2 so that it can be divided into 45-packs, for example, with a volume that can be divided into numbers.

  The powder dividing rod 10 is provided between a support block 11 extending in the longitudinal direction of the machine body 1, end plates 12 and 12 disposed at both ends of the support block 11, and the end plates 12 and 12. The opening / closing plate 13 that forms a V-shaped split rod by the support block 11 and the partition plate 14 that is provided inside the split rod and is movable in the longitudinal direction. The opening / closing plate 13 is connected to the end plates 12 and 12 with a pin 15 and is normally kept in contact with the front surface of the support block 11 with the lower end facing and closed. The support pin 15 is made pivotable from the closed position as indicated by a two-dot chain line. In addition, what is shown by the code | symbol 17 in FIG. 3 is a stopper which prevents rotation of the opening-and-closing plate 13 more than the predetermined angle.

  A dividing restriction means 20 for restricting the movement of the partition plate 14 along the one end plate 12 is attached to the inside of the powder dividing rod 10 thus formed. The division restricting means 20 is fitted along the inner surface of one end plate 12 and is fitted into a slightly thicker support portion piece 21 and a groove portion 22 provided on the support portion piece 21 in the vertical direction. Is provided with a pin 24 supported by the support piece 21 so as to be tilted up and down, and a locking mechanism 25 (for example, a magnet) that holds the state when the restriction piece 23 stands up and fits into the groove 22. Adsorption holding).

  The length of the restricting portion 23 is set to a length that restricts the space for three divisions when the length of the restricting portion 23 falls on the support pin 24 with respect to the support piece 21 at the base portion 23a. Is protruded and attached so that it can be manually picked from the upper end of the support piece 21 and rotated (raised). And the magnet 25a is inserted in the intermediate part of the restriction | limiting part piece 23, for example, the steel piece 25b is distribute | arranged to the position facing the magnet 25a in the state accommodated in the standing groove part 22, and both A locking mechanism 25 is provided that is attracted and held by magnetic force. When the restricting piece 23 is raised and fits in the groove 22 of the support piece 21, the partition plate 14 is set so that the outer surface matches or falls below the surface of the support piece 23. Is preferably moved to the inner end of the powder dividing basket 10 because it does not hinder the maximum number of divisions (45 packets).

  By configuring in this way, the powder dividing rod 10 is a rod in which the V-shaped interior surrounded by the other end plate 12, the partition plate 14, the support block 11 and the opening / closing plate 13 divides the powder. Therefore, if an opening operation of the opening / closing plate 13 is performed after a required amount of powder is put into the space that becomes the dividing rod and the surface is leveled, the opening / closing plate 13 is rotated to a position indicated by a two-dot chain line. Therefore, the powder falls into the powder storage body 4 below and is divided at the same time. Thereafter, it is sequentially discharged from the chute to the packaging part by a well-known means, enclosed in wrapping paper, and packaged.

  Therefore, at the time of general packaging operation, the number of divisions is set in accordance with the scale 17 displayed by dividing the partition plate 14 into the upper edge on the support block 11 side in the dividing basket 10. Often used, it is divided into three packs per day for one week (21 packs) or two weeks (42 packs). Therefore, for example, when working as a single package of 42 packages, if the regulating part 23 of the division regulating means 20 is tilted, the partition plate 14 can be moved when setting the normal maximum number of divisions. The movement of the partition plate 14 is prevented by the tip of the restricting piece 23, and if the divider plate 14 is stopped at a position where it abuts on the restricting piece 23, it can be divided into 42 packages, and further divided. There is nothing. Accordingly, errors in division can be prevented in advance.

  If the restricting piece 23 is raised and returned to the support piece 21, the restriction of the partition plate 14 is released by the dividing restricting means 20, so that the inside of the dividing rod 10 becomes the maximum space and is divided into 45 packages. It can be packaged.

  FIG. 5 is a cross-sectional view showing another embodiment of the division regulating means in the powder divided basket. In this embodiment, as the division restriction means 20A, a restriction piece 23a is attached to the holding piece 14A of the partition plate 14. In the same manner as in the above-described embodiment, the restricting piece 23a has a length that restricts the space of three divisions when the length dimension of the restricting piece 23a falls on the support pin 24a with respect to the holding piece 14A at the base. The upper end of the holding part piece 14A is attached so as to protrude by hand from the upper edge of the holding part piece 14A. In addition, the restricting piece 23a is adapted to be accommodated in the groove 14b provided in the holding piece 14A in a standing state, and a magnet 25a is fitted in the intermediate portion, and faces the magnet 25a in the standing state. For example, when the partition plate 14 is normally moved by the locking mechanism 25 that is attracted and held by a magnetic force with, for example, a steel piece 25b arranged at a position, there is no problem.

  According to the division restricting means 20A thus configured, with the restricting portion 23a to be attached to the holding portion piece 14A of the partition plate 14 being tilted, the partition plate 14 is directed to the maximum movement position in the powder dividing rod 10. If the movement is stopped, the movement is stopped at the position where the restricting piece 23a is in contact with the inner end of the powder dividing rod 10, so that it is prevented from moving beyond the normal maximum number of divisions as in the above embodiment. The number is correctly set to 42 packets. When the restricting piece 23a is erected and stored in the groove 14b of the holding piece 14A, it is locked by the locking mechanism 25, so there is no problem in moving the partition plate 14, and the final end of the powder dividing rod 10 When it is moved to 45, it is possible to divide 45 packages, which is the maximum number of divisions.

  Further, if the partition block 30 shown in FIG. 6 is used in a state in which the regulation by the division regulation means 20 is released, the number of powders divided into the division basket 10 can be divided into two blocks. . The partition block 30 is a block body having a width corresponding to, for example, three divisions so that the lower half is in contact with both sides of the support block 11 and the opening / closing plate 14 of the split cage 10, and is detachable. It is a thing. Although such a partition block 30 is not shown in the drawing, for example, when the number of divisions of the dividing basket 10 is set to 45 packets and arranged at an intermediate position thereof, a measurement compartment for 21 packages is formed on the right and left. It will be. Accordingly, the powder for patient A and the powder for patient B are put in one of them, and the powder for patient B is put in and smoothed, and when the opening and closing plate 14 is opened, both powders are simultaneously divided into the powder container 4. It is dropped and divided, and it becomes possible to divide 21 packets by a series of operations without mixing two kinds of medicines. The partition block 30 is kept stationary even if the opening / closing plate 14 is opened, and there is no problem. Of course, once it has been used, removing it does not interfere with the subsequent packaging work.

  As described above, the dividing machine according to the present invention has a simple structure and can rationally regulate the number of divisions when the powder is packaged. Therefore, in a busy pharmacy, it eliminates the inconvenience during the packaging operation. Therefore, it can be said that the effect of preventing the occurrence of errors is great.

  In the above description, when the regulation part of the required length pivotally supported by the base part on the support part piece or the holding part piece of the partition plate provided at the split collar end part as the division regulation means is configured to regulate the number of packages In addition to this, as shown in FIGS. 7 (a) and 7 (b), the support block 11 in the above-described embodiment constituting the powder divided cage 10 or the inner surface of the opening / closing plate 13 (forming the divided cage) In the normal state, it fits on the same surface along the surface at one end, and protrudes from the surface by standing up (corresponding to the defeat of the present invention) at the time of regulation (in FIG. A restriction piece 20B is provided so as to be able to be tilted by a pin 26. Alternatively, as shown in FIG. 7B, the restriction piece 20 </ b> C is provided so as to be tilted by being supported by the pin 27 so as to protrude toward the inner surface side of the opening / closing plate 13 during restriction. And if these control pieces 20B or 20C are made to protrude to the inner surface side, the movement of the partition plate 14 can be prevented and the number of divisions can be controlled. Of course, when the regulating piece 20B or 20C is tilted, the partition plate 14 can be moved. The restricting pieces 20B and 20C are preferably provided at positions where there is no hindrance to the powder leveling operation.

  Also, a base piece is supported on the support piece and a piece that protrudes from above into the split cage is provided to restrict the movement of the partition plate, or a groove is provided in the support piece or end plate as described above. Thus, it is also possible to use a restricting piece that engages the base end with this groove and inserts it into the inside of the bag. These also belong to the category of the present invention.
