Description

[Detailed description of the invention] This invention relates to a fully automatic tablet packaging machine, which mainly uses a tablet case that utilizes a vertical drawer that juxtaposes tablet feeders for storing tablets. The present invention relates to a device that facilitates exchange and increases the number of drug types.

As a result of examining patients in hospitals, clinics, etc., it has been found that when giving tablets according to symptoms, it is often necessary to package multiple types of tablets in the same package, which makes the process complicated and difficult for patients. This can easily result in a long wait time.

In order to deal with the above problems, various automatic tablet packaging machines have been developed.
These base structures have been put into practical use, but tablet feeders that store multiple types of tablets are sequentially arranged in tablet shelves with multiple stages, and a hopper and a hopper that can collect the tablets discharged from all the tablet feeders are installed. It is dropped into a packaging mechanism via an input mechanism to automatically create sachets.

In small-scale devices, the tablet racks mentioned above are provided with one row for each stage, and in medium-sized devices, a structure is adopted in which tablet feeders are placed side by side on the front and rear sides with a partition in the center. has been done.

However, if we expand the number of medicines and increase the shelf dimensions,
Since the opening/closing lid must be correspondingly large, the packaging machine is not necessarily perfect in terms of packaging speed, installation space, airtightness, and dust-proofing, especially when controlling the temperature and humidity of chemicals. If the temperature and humidity adjustment units are provided close to each other, the deterioration of the airtightness has the disadvantage of being fatal to the temperature and humidity adjustment effect.

The present invention was developed in view of the above, and aims to provide a fully automatic tablet packaging machine that not only increases the number of medicines, but also has perfect airtightness and dust-proofing properties, and allows the entire device to be configured compactly. It is something to do.

Although the configuration and operation mode of the fully automatic tablet packaging machine according to the present invention have been described in detail above, the present invention has various advantages described below and brings about effects in use.

In other words, by adopting a so-called cabinet-type pill shelf system using vertical drawers instead of the conventional medicine shelf system, it is possible to increase the number of tablet types and tablets, and the overall device can be made more compact. It is.

Furthermore, when the tablets are stored, the airtightness is perfect and the effect of blocking them from the outside air is great, and when replacing or filling tablets, it is only necessary to mist each drawer, so it can be operated with minimal exposure. It is also advantageous in terms of dust resistance.

Even during operation, all work can be done from one side of the vertical drawer, improving work efficiency.

By increasing the airtightness and dustproofness as described above, the effect of controlling the internal temperature and humidity by attaching the temperature and humidity control unit 7 shown in FIG. 1 is extremely large.

Furthermore, tablets based on special prescriptions, easily destroyed tablets that cannot be removed from the tablet feeder, tablets with special shapes, etc. are pre-distributed by the action of the hand-dividing dispenser 12 and the conveyor 13, and the intermittent movement of the conveyor 13 is performed. Since the operation of sequentially dropping the tablets into the common hopper 11 can also be used, any combination of tablets is possible and can be stored and packaged in the same sachet.

Furthermore, if the input device (not shown) is equipped with various input keys, 1 kana character key, and a function key on the operation desk, as well as a CRT display for checking input signals, it is possible to prevent operational errors. .

Furthermore, the use of a memory allows input signals to be input continuously, which improves work efficiency, and has the effect of allowing extremely high-speed packaging to be carried out in conjunction with the operation of the continuous packaging mechanism.

This device is constructed as described above, so when replacing or replenishing tablets, all you have to do is pull out each vertical drawer unit toward you.
Compared to opening the lid that covers the entire surface of a conventional tablet shelf, the amount of exposure inside the case can be minimized, making it highly effective against dust and suitable for controlling temperature and humidity inside the case. In addition, all tablet replacement and replenishment work can be done on one side of the vertical drawer.
Work efficiency can be improved compared to when working from both the front and back sides of a conventional tablet shelf.

Furthermore, since the large number of distribution cells partitioned along the insertion/removal direction of the hand-splitting device can be turned upside down by rotation, there is no need for sliding space, which is required when sliding the bottom plate, and the hand-splitting The width of the distributor can be reduced to the minimum necessary, so it can be easily applied to narrow vertical drawers, and if necessary, it can be installed independently in two or more vertical drawers. It has excellent effects such as:
