DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings.

[0012] Reference numeral 1 is a tablet packaging machine intended for tablets among drugs. This packaging machine consists of a casing 4 having a drug storage section 2 at the top and a packaging machine section 3 at the bottom, and a casing 4 that is inserted into a grid-like partition plate 5 of the drug storage section 2 and arranged in a plane, elongated in the vertical direction. A plurality of formed tablet cases 6, a loading mechanism 7 that takes out a predetermined number of tablets from the lower part of a selected one of the tablet cases and puts them all at once into a packaging bag, and a tablet takeout operation and loading mechanism of the tablet case 6. 7 and a control device 8 for controlling the tablet loading operation etc., and the packaging bag into which the tablets are loaded is sealed and packaged.

The casing 4 has a sliding door 9 on the top surface.
is attached, and by sliding this door, the top surface is opened to expose the lattice-shaped partition plates 5 and the tops of the tablet cases 6 arranged between the partition plates. The partition plate has 12 columns in the depth direction, and is modularized with 10 rows as one unit. (However, these columns and rows are not limited to this.) Therefore, one module can accommodate 120 types of tablets, that is, 120 tablet cases 6, and multiple modules can be connected. Accordingly, 120,240,3
It can be configured to store 60,480 types. A stepped bottom plate 10 with a concave center is disposed below the grid-like partition plate 5, and an electrical connector 11 is attached to the portion of the bottom plate that contacts the tablet case 6.

The tablet case 6 is inserted into the electrical connector 11 to be electrically connected to the control device 8, and exchanges drive signals and detection signals.

[0015] Since the bottom plate 10 is formed in a stepped shape, it can accommodate two types of tablet cases 6A and 6B having different lengths, as shown by the dashed line in Fig. 4.
This makes it possible to store the appropriate number of tablets even with tablets of different sizes.

As mentioned above, the tablet case 6 is vertically elongated in the form of a column (length 300 mm), and the upper part contains a cylindrical (φ46 mm) transparent tablet case 12 for storing tablets, and the lower part has a prismatic shape. A mechanism section 13 is formed to be detachable.

The mechanism section 13 has a groove 60 for vertically arranging a plurality of tablets at one location on the side, a guide surface 61 sloped downward toward the groove 60, and a passage for the tablets on the outer periphery. an alignment body 59 formed with an alignment member 62 protruding circularly on the guide surface 61; and a semicircular plate-shaped bearing body 98 fixed to a case to support a drive shaft 99 of the alignment body. , a disk-shaped fixing plate 66 having a notch 63 on a part of its outer periphery through which the tablet falls, and a partition plate 65 interposed in a slit 64 formed in the middle of the groove 60; and a square column-shaped support. A stand 67, a connecting frame 100 that connects this support stand and the tablet case 12, and a connecting frame 100 that is attached to this support stand 67 and moves the alignment body 59 into the groove with a drive shaft 99 provided at the center of the alignment body as a fulcrum. A swinging mechanism 68 that swings between a position where the partition plate 65 is interposed (the position shown in FIG. 1) and a position where the partition plate 65 is not interposed (the position shown in FIG. 2), and a support for driving this swinging mechanism 68. A drive device 70 consisting of a gear reducer (not shown) built into the stand 67 and a DC motor 69
It consists of

The partition plate 65 mounted on the fixed plate 66 is supported by a support 72 through a long hole 71, and
It is constantly biased by a spring 73 in the direction shown by the arrow in FIG.

The swinging mechanism 68 includes an eccentric pin 74 connected to a DC motor 69 via a gear reducer, and one end connected to the support column 7.
6, the eccentric pin 74 is engaged in a long groove 77 provided on the central lower surface, and a swinging plate 79 having a swinging pin 78 (vertically extensible and retractable) protruding from the upper surface of the other end is formed at one end. The cut groove 80 is engaged with the swing pin 78, and the support 81 protruding from the upper surface of the other end is connected to the drive shaft 99 of the alignment body 59.
A fan-shaped connecting piece 84 is connected to the connecting piece 84.

A detector 85 is connected to a tablet falling path 86 provided on the side of the support base 67 and is detachably attached to the upper surface of the support base 67. It has a structure in which a light receiving element 88 and a light receiving element 89 face each other, and a signal is generated by the tablet passing through the recess 87 and blocking light.

[0021] Inside the tablet case 12, an alignment body 59 and a fixing plate 66 constituting the mechanism section 13 are fixed.
The structure is such that the parts above the connection piece 84 in FIG. 3, the parts below the swing plate 79, and the connecting frame 100 are separated.

Tablet case 6 configured as described above
When a tablet ejection signal is input from the control device 8, the DC motor 69 constituting the drive device 70 rotates, and the eccentric pin 74 and the swing plate 79 convert the rotational motion into a swinging motion. This oscillating motion is transmitted to the alignment body 59 via the connecting piece 84, and the alignment body 59 moves to the position where the partition plate 65 is interposed in the groove 60 with the drive shaft 99 of the alignment body as a fulcrum as described above (see FIG. 1) and a non-intervening position (the position shown in FIG. 2).

The tablets housed in the tablet case 12 enter the groove 60 by the guide surface 61, but when the alignment body 59 is in the position shown in FIG. At rest.

Thereafter, when the alignment body 59 swings to the position shown in FIG.
The lowermost tablet, which was stopped on 5, falls onto the fixing plate 66. Then, the alignment body 59 starts to swing again toward the position shown in FIG.
3. It is discharged through the falling passage 86.

At this time, since the falling tablet passes through the recess 87 of the detector 85, a signal indicating that one tablet has been ejected from the tablet case 6 is detected, and this signal is sent to the control device 8. .

Here, the gear reducer in the support base 67 is set to reduce the rotation of the DC motor 69 to about 1/100, and when the eccentric pin 74 rotates once, the swing plate 79 rotates once. One tablet is ejected by swinging (movement from the position of FIG. 1 to the position of FIG. 2 and back to the position of FIG. 1 again). The time required for one reciprocating swing is 0.4 to 0.5 seconds, and the tablets aligned in the grooves 60 and placed on the partition plate 65 instantly fall onto the fixing plate 66 and are then removed by the partition plate 65. It is separated and falls downward.

Further, as shown in FIG. 3, on the guide surface 61 of the alignment body 59, an alignment member 62 that defines a tablet alignment groove 102 between the circumferential surface of the alignment member 61 and the tablet case 12 is removably attached. It is installed. That is, the alignment member 62 is attached by fitting the legs 103 protruding from the lower surface into the holes 101 of the guide surface 61.

According to this configuration, it is possible to form the optimal alignment groove 102 for the stored tablets by a simple operation of appropriately replacing the alignment members 62 of different sizes depending on the size and shape of the tablets. , the groove 60 from above the guide surface 61
Tablets can be guided smoothly to improve performance and convenience.

Furthermore, since the series of operations of aligning, separating, and ejecting the tablets can be reliably performed by the swinging mechanism 68 with small displacement, the mechanical part 13 is smaller than the conventional rotating mechanism.
can be made smaller, and the tablet case 6 can be made more compact.

Furthermore, since the swing mechanism 68 can be constructed with simple and small parts such as the swing plate 79 and the partition plate 65, the structure of the tablet case 6 can be simplified.

Furthermore, the tablet case 6 is similar to the tablet case 1.
2, the connecting frame 100, and the support stand 67 can be separated, so that workability such as cleaning the tablet case 12 can be improved. In addition,
Support stand 67 and connection frame 1 already set in the tablet packaging machine
When setting the tablet case 12 on the tablet case 12, simply rotate the connecting piece 84 on the side of the tablet case 12 manually to engage the groove 80 of the connecting piece and the swing pin 78 of the swing plate 79. Moreover, since the lower outer peripheral surface of the tablet case 12 is guided by the protrusions 95 provided on all sides of the connecting frame 100, the tablet case can be easily and smoothly inserted. .

Furthermore, since the partition plate 65 mounted on the fixed plate 66 is constantly biased by the spring 73 in the direction shown by the arrow in FIG. 65, the partition plate 65 slides in the horizontal direction against the force of the spring 73, protecting the tablet and ensuring that the next swinging motion will allow the tablet to be properly restored. Tablets can be dropped.

Further, as shown in FIG. 4, reference numeral 35 denotes a hopper having a triangular cross section that is high at the front and back and low at the center, and the tablets discharged from the tablet case 6 are guided by this hopper 35 to the center of the hopper in the front and back direction. Ru. This hopper has a structure that is simply locked to the casing 4, and can be removed without using any special tools, making cleaning such as removing powder powder easy. A pair of conveyors (not shown) are installed at the bottom of the hopper 35, and the tablets dropped at the center of the hopper 35 in the front and back direction are transferred to the center in the left and right direction.

The charging mechanism 7 is a movable container 39 which is movable in the front-back direction and whose bottom plate is opened when it moves forward.
and a paper opening device that widens the entrance of the container before it is inserted into the medicine packaging paper. When the tablets collected in the movable container 39 by the conveyors 36 and 37 are collected for one package, the container is moved forward. It moves horizontally, the bottom plate is opened, and the tablets are placed in the drug wrapper.

The packaging machine section 3 includes a roller 42 around which a packaging sheet 41 which can be thermally welded and which has been folded in half in advance is wound around, a tension arm 43, and a tension arm 43 that heat-seals the packaging sheet into a T-shape to form a continuous pouch. a T-shaped heat-sealing mechanism 44, a printer device 45 that prints predetermined items such as prescription data on each sachet, a feed roller 46 that intermittently feeds the sheet-shaped sachet, and a The conveyor 48 conveys the sachets to the medicine package outlet 47. Then, the feed roller 46 is intermittently driven by a drive motor (not shown) to feed the packaging sheet 41, and when the feeding is stopped, the heat sealing mechanism 44 heat-welds the compartment of each sachet and the lower half of the opening side. A sachet with the upper half of the opening side open is formed, and the opening of the sachet is pushed open by the paper opening device, and a movable container 39 is opened to accommodate one package of tablets. is inserted, the bottom plate of the container is opened, and one package of tablets is put into the sachet. After this,
By the operation of the heat sealing mechanism 44 accompanying the next sachet forming operation, the opening of the upper half of the sachet is thermally welded, and the sachet containing the tablets is sealed. Here, simultaneously with the operation of inserting tablets into the sachets by the above-described loading mechanism 7, prescription data is printed onto the sachets by the printer device 45. Finally, the conveyor 48 delivers the sachets in a continuous sheet to the medicine package outlet 47 located above. It should be noted that the packaging sheet 41 passing through the feeding mechanism 7 is fed vertically downward with the fold line facing toward you, as shown in FIG.

As described above, the drug supply device of the present invention, that is, the tablet case 6, has a vertically elongated columnar shape and has a small bottom area. Therefore, when the drug supply device is mounted on the drug packaging machine 1, it is arranged in a plane. Therefore, the height of the drug packaging machine 1 can be significantly reduced even if the capacity and number of devices arranged are the same as in the past. As a result, usability for the user can be improved. In addition, all of the drug discharge ports 31 of the tablet case 6 are also located in a plane at the bottom of the supply device, so the drug discharged from the tablet case 6 to the hopper 35 is discharged from a considerably low position. , it is possible to significantly reduce damage caused by falling drugs, and also to shorten the falling time, contributing to faster packaging operations.

Furthermore, since the tablet cases 6 can be arranged in a flat plane, there is no need for a conventional drop path shared by each tablet case 6, and the cases 6 can be pulled out while the drug packaging machine 1 is in operation. There is no possibility that the medicine will jump out of the machine from this extraction part, and even if the medicine is not extracted, there is a medicine case 12 on top of the tablet case 6, so there is no possibility that the medicine will be thrown into the tablet case 6 even when the medicine packaging machine is in operation. Medicines can be easily replenished and the user's work efficiency can be improved.

[0038]

As described above, according to the present invention, alignment grooves suitable for the stored drugs can be formed by the simple operation of changing the alignment member according to the size and shape of the drug. It is possible to provide a convenient drug supply device with good performance and smooth guide of the drug from the groove to the hole.
