Description

[Detailed description of the invention] [Industrial application field] This invention relates to a small tablet packaging machine that can manually divide tablets into desired number of tablets and package them one by one. It is.

[Prior Art] Generally, as a result of examining a patient at a hospital, clinic, etc., it becomes necessary to provide tablets to the patient. Since it is sealed in sachets, it takes a long time for adjustment and patients are kept waiting for a long time.

To avoid this, automatic tablet packaging machines have been developed and put into practical use in recent years.

[Problems to be solved by the invention] However, all conventional automatic tablet packaging machines have a feeder that stores different tablets, a hopper and a feeding mechanism that can collect tablets selected from the feeder. , the basic configuration is a packaging mechanism connected to the loading mechanism and a computer system for automatically controlling the operation of each of the above mechanisms, so the device itself becomes large and
Due to its high price, although it can be used in large hospitals, it is difficult to use in small and medium-sized municipal hospitals, private hospitals, and clinics. Problems such as the fact that the above-mentioned work is currently being carried out by hand, regardless of the situation.

This invention solves the above-mentioned problems of the conventional methods, and is convenient for packaging tablets into desired sachets by hand-dividing them.In addition, it is small and lightweight, making it easy to handle. The purpose of this invention is to provide a small-sized tablet packaging machine that is inexpensive.

[Means for Solving the Problems] In order to achieve the above object, this invention has a plurality of tablet buckets connected to a rotating chain on a support plate so as to be able to rotate endlessly, and the bottom surface of the tablet buckets is A tablet drop hole is provided at a predetermined position of the supporting plate to allow the tablets to fall from the tablet bucket located at this position, and the tablets dropped from the tablet bucket are thrown into the lower part of the tablet drop hole via the input section. It is equipped with a packaging mechanism that allows

[Function] By adopting the above-mentioned means, this device manually divides the tablets into a plurality of tablet buckets, and then rotates the tablet buckets using a rotating chain.
The tablets in the bucket fall in order from the one that reaches the position of the tablet drop hole provided on the support plate, and are fed into the packaging mechanism via the feeding section where they are packaged one by one.

[Example] Hereinafter, an example of this invention shown in the drawings will be described.

The drawings show one embodiment of this invention, however,
The small tablet packaging machine shown in the drawing is configured to be able to pack not only tablets but also powders.

In FIG. 1, 1 is a machine casing, above which a plurality of tablet dividing cells 2 are fixedly installed, and a powder uniform dispersion mechanism 3 is arranged in parallel. 4 is a partition plate that determines the number of powder packages, and is set to be movable as desired. A packaging mechanism 5 is installed in the lower part of the machine casing 1, and, as will be described later, incorporates a mechanism for hermetically packaging loaded tablets one by one. A lid 6 is provided on the top surface of the machine casing 1, and is configured to be opened and closed together with a side lid 7.

In FIG. 3, both the lid 6 and the side lid 7 are opened to reveal the internal structure. That is, a common opening/closing shutter 8 (FIG. 2) is provided on the bottom of the divided tablet mass 2 fixedly installed as described above, and a plurality of tablet buckets 9 are connected to the rotary chain 1 under the shutter 8 (FIG. 2).
One end is connected to 0, and it is installed so that it can rotate endlessly. 11 is a support plate that supports the tablet bucket 9, and a tablet drop hole is provided near the center (position A in FIG. 2).

On the other hand, the uniform powder dispersion mechanism 3 includes a swinging opening/closing plate 12 as a swinging dropping mechanism, and a rotating chain 14 connecting a plurality of powder buckets 13 below the falling end of the swinging opening/closing plate 12 . Reference numeral 15 denotes a support plate that supports the uniform dispersion mechanism 3, and as in the case of the tablet bucket 9, the powder bucket 13 is installed so as to be able to rotate endlessly along the rotation chain 14, and in the vicinity of the tablet drop hole. A powder drop hole is provided.

Reference numeral 16 denotes an electric motor, whose rotating shaft changes the direction of rotation of the motor via an umbrella gear 17, and is connected to an opening/closing shutter 8 by a drive rod 18 for opening/closing operations. The rotational force of the rotating transmission shaft 19 is transmitted to the support rods 20 and 21 via a cam or gear, and the swinging opening/closing plate 12 is swinged to cause the powder to fall completely. .

The tablets stored in the tablet bucket 9 are placed on the support plate 1
Since there is no problem even if the top surface of 1 is directly moved, the bottom of the tablet bucket 9 can be left open without providing a bottom lid, but the bottom of the powder bucket 13 is equipped with a bottom lid that can be opened and closed. For example, a simple opening/closing mechanism using a magnet may be used to easily open above the powder drop hole and automatically close as the bucket moves. Note that the opening/closing mechanism described above can be realized very easily, so its details will be omitted. Further, the tablet bucket 9 can also have a similar configuration.

FIG. 4 shows the packaging mechanism portion from the front side, and the electric motor 22 drives the rotation chain 14 for endlessly rotating the powder bucket 13 via gears 22a and 22b. Reference numeral 23 indicates an input section for tablets and powders, and 24 indicates a roll for supporting wrapping paper, which together with the T-shaped thermocompression bonding mechanism 25 of the packaging mechanism 5 and the wrapping paper presser mechanism 26 constitute a packaging mechanism.
Additionally, the thermocompression bonding part is tilted at approximately 45 degrees to facilitate ease of operation. 27 is a wrapping paper sheeting mechanism.

FIG. 5 shows the packaging mechanism part from the back side, and the electric motor 28 is connected to the main shaft 31 by gears 29 and 30.
The shift mechanism driving section 23 and wrapping paper holding mechanism driving section 33 connected to the main shaft 31 are operated, and the tablet bucket 9 is rotated through an umbrella gear 34.
It is designed to rotate endlessly. That is, by the operation of the known intermittent shifter mechanism 35, the tablet bucket 9 is configured to move along the rotation chain 10 by only one tablet per rotation of the rotation shaft 36.

Next, the operation of the above will be explained.

First, according to the desired packaging order, for example, the order of taking tablets or powders to be taken three times a day in the morning, noon, and evening, and the combination thereof, the tablets are manually divided into the tablet dividing squares 2, and at the same time. Alternatively, after setting the number of packages of powder to be separately sealed using the partition plate 4, the powder is spread evenly within the swinging opening/closing plate 12.

Next, when the switch of the electric motor 16 is turned on, the drive rod 18 is operated and the opening/closing shutter 8 is opened, and all the divided tablets are transferred to the tablet bucket 9.
fall inside. In parallel with the above operation, the rotational force of the transmission shaft 19 is applied to the support rod 2 for the uniform powder spreading mechanism 3.
0 and 21, the swinging opening/closing plate 12 is appropriately swung, and the evenly spread powder is completely dropped into the powder bucket 13.

Next, when the electric motors 28 and 22 are operated, the tablet bucket 9 and the powder bucket 13 start rotating, respectively. At this time, in order to adjust the timing at which tablets and powders start falling into the packaging mechanism 5, each of the tablet bucket 9 and powder bucket 13 is removed from the intermittent drive mechanism, and the tablet and powder drop holes, that is, the input portions, are removed from the intermittent drive mechanism. 23
It can also be positioned directly above. Tablet bucket 9 reached above the tablet drop hole
The tablets then fall into the input section 23, and the bottom cover of the powder bucket 13 that reaches above the powder drop hole is automatically opened and the powder drops into the input section 23. Such falling tablets and powders can be
This continues intermittently as the powder bucket 13 circulates.

On the other hand, the shift mechanism 27 in the packaging mechanism 5 is
Since the power is taken in from a shift mechanism drive unit 32 connected to a main shaft 31 rotated by an electric motor 28, wrapping is performed continuously while shifting the wrapping paper at the same timing as the medicine falls into the bucket. The wrapping paper is made of paper that can be bonded by thermocompression, such as laminate or parchment paper, which is folded in half and rolled up, and after the direction is changed by the roll 24, it is bonded by thermocompression by the T-shaped thermocompression bonding mechanism 25. The wrapping paper holding mechanism 26 functions to firmly grip the paper while preventing scattering of the powder agent to ensure packaging, and then the shifting mechanism 27 sequentially sends out the paper while the packaging operation progresses.

A control system 37 shown in FIG. 5 incorporates a control mechanism that can automatically proceed with the operation after manually dividing the tablet or powder. The switch group 38 shown in FIG. 1 incorporates a power supply, a start switch, a shift mechanism speed changeover, an automatic manual changeover switch, etc. For example, when switching to manual mode, the above operations can be performed as desired. The output of the control system 37 is controlled so as to perform an intermittent operation such that only one package is produced.

In the above embodiment, a device capable of handling not only tablets but also powders has been shown, but this invention can of course be configured as a packaging machine that handles only tablets, in which case it can be configured to be smaller than the one shown in the above embodiment.

On the other hand, the device shown in the above example can be used for dividing and packaging not only tablets but also powders. Packaging can also be done. The distribution of the powder can be set using the partition plates 4, but if a plurality of partition plates 4 are used, an arbitrary distribution state can be obtained. In addition, if a proximity switch that responds to the movement of each bucket is installed at an arbitrary location, it is easy to count the number of separate packages. In addition, the tablets and powders are distributed to the tablet dividing mass 2 or the powder uniform distribution mechanism 3, and the tablets and powders are distributed to each bucket by opening the opening/closing shutter 8 and swinging the swinging opening/closing plate 12. 9, 13, the opening/closing shutter 8 and the swinging opening/closing plate 12 can be opened immediately to proceed to the next step of distributing the medicine, so there is no need to wait until all the distributed medicines have been packaged. This has the advantage that it is possible to proceed with work extremely efficiently.

In addition, when carrying out complex packaging operations, such as cases in which the tablets administered to a patient are different in the morning, noon, and evening according to a doctor's prescription, predetermined tablets are distributed manually into the tablet dividing squares in advance. If the machine is then started and driven, it is possible to obtain successive sachets in the order in which they were distributed. Each of the tablet division squares has a number or a symbol “Morning” corresponding to the dosing time.
If you write "day", "evening", etc., you can effectively use it as a guideline when allocating.

Furthermore, in the above embodiment, the tablet dividing square 2 is provided above the tablet bucket 9, and the tablet dividing square 2 is provided above the tablet bucket 9.
Although the tablets are manually divided in the above embodiment, the tablets may be manually divided directly into the tablet bucket 9 without providing the tablet dividing space 2. In addition, in the above embodiment, the tablet bucket 9 is connected to the rotary chain 10. Although the rotating chain 10 may be, for example, in the form of a suitable endless belt, it goes without saying that this invention can be modified in various ways to the above-described embodiment.

[Effects of the invention] Since this invention is configured as described above, it is possible to automate operations other than hand-dividing operations such as tablet selection and bagging, which were conventionally performed only manually. , the time for dispensing and packaging tablets based on a doctor's prescription at hospitals, etc. is extremely shortened, patients no longer have to wait for long periods of time, and the device itself is small and lightweight, easy to handle, and is fully automated compared to conventional methods. It is cheaper in price than the automatic tablet packaging machines of In particular, it has excellent effects such as being able to realize a compact mechanism.
