Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tablet identification device for identifying the shape of a tablet.

[Prior Art] In general, when tablets are packaged into single doses using various tablet packaging machines at a hospital pharmacy, for example, the tablets contained in each packaging bag are not properly packed according to the prescription. To confirm that there are no mistakes, pharmacists are conducting an audit of the tablets contained in each sachet.

[Problems to be Solved by the Invention] However, tablets come in extremely diverse shapes, colors, and sizes, and in particular, there are dozens of shapes, so only a highly skilled pharmacist can handle them. It is difficult to accurately identify the tablets contained in sachets, and there are very few highly skilled pharmacists, even in large hospital pharmacies where a considerable number of pharmacists work. The reality is that it is limited, and therefore,
Even if the tablet packaging process is automated using various tablet packaging machines, the task of auditing the packaged tablets must be left to a small number of highly skilled pharmacists; Problems such as increasing the processing capacity of tablet packaging operations increased the burden of tablet inspection work on the small number of highly skilled pharmacists.

This invention solves the above-mentioned problems of the conventional methods and can identify the shape of a tablet. Therefore, if it is applied to, for example, tablet inspection work, it can reduce the burden of tablet inspection work on pharmacists. The object of the present invention is to provide a tablet identification device.

[Means for Solving the Problems] In order to achieve the above object, the present invention accepts data regarding the shape of a tablet and divides it into first data viewed from a predetermined direction and second data viewed from another direction. a means for dividing a first
means for receiving data and classifying the data into a plurality of types according to contour shapes;
The apparatus is equipped with means for receiving data and classifying the data into a plurality of types according to contour shapes, and means for receiving data classified from both of the classification means and processing the data in combination with each other.

[Function] By employing the above means, the present invention includes means for classifying the first data viewed from a predetermined direction according to the outline shape;
The second data viewed from another direction is classified according to the contour shape, and then combined with each other by the processing means, so that the second data is classified according to the shape of the tablet. For example, if applied to tablet inspection work, the burden on pharmacists of tablet audit work will be significantly reduced.

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

FIG. 1 shows an embodiment of the present invention, in which data 1 receives data regarding the shape of a tablet having length a, width b, and thickness c, and converts it into data regarding a and b.
This is a dividing device that divides data into data related to b and c. 2 receives data regarding a and b from the dividing device 1, and determines whether the surface containing a and b is circular (for example, the abbreviation is O) or where a > b and a straight line portion along a. (for example, the abbreviation is LF), those that have a>b and no straight line along a (for example, the abbreviation is LR), and regular polygons or similar things (for example, the abbreviation is N). ).

3 receives the data regarding b and c from the dividing device 1, and divides the surface including b and c into a straight line along b and c (for example, the abbreviation is F) and a straight line along c. There are three types: one that has only a part (for example, the abbreviation is M), one that has an elliptical shape that does not have a straight part (for example, the abbreviation is R), and one that is circular (for example, the abbreviation is O). It is a classification device that classifies each.

A processing device 4 receives the classified data from both the classification devices 2 and 3, and processes the data by combining them with each other.

That is, the processing device 4 receives the information from the classification device 2 such as a,
If data (i.e. O) in which the surface including b is circular is received, and data (i.e. F) in which the surface including b and c is straight along b and c is received from the classification device 3, the two are combined. data (abbreviated as OF) is output, and the classification device 2 outputs data whose surface including a and b is circular (i.e., O).
is accepted, and from the classification device 3 the surface containing b and c is c
If it receives data that has only a straight line part along ), and if the classification device 3 receives elliptical data (i.e. R) in which the surface including b and c does not have a straight line, it outputs data (abbreviated as OR) that is a combination of both, and then 2 to a,
If data in which the surface including b is circular (i.e. O) is received, and data in which the surface including b and c is circular (i.e. O) is received from the classification device 3, data that is a combination of both (abbreviated as OO) is output. It's becoming like that.

Further, the processing device 4 receives data (i.e. LF) in which the plane including a and b has a straight line portion along a where a>b and the plane including b and c from the classification device 3. When receiving data (that is, F) that has straight line portions along c, outputs data that combines both (abbreviated as LFF), and also outputs data (abbreviated as LFF) that is a combination of both, and the classification device 2 also outputs data that includes a and b when a>b and a It receives data (i.e. LF) having a straight line part along
When receiving data (i.e. M) in which the surface containing only a straight line part along c, outputs data that combines both (abbreviated as LFM), and
The classification device 2 accepts data (i.e. LF) in which the surface containing a and b has a straight line portion along a where a>b, and the data (i.e. LF) in which the surface including b and c has an elliptical shape with no straight line portion is received from the classification device 3. When data (i.e. R) is received, data (abbreviated as LFR) which is a combination of both is outputted, and further a,
When receiving data (i.e. LF) in which the surface including b has a linear portion along a where a>b and data (i.e. O) in which the surface including b and c is circular from the classification device 3, both are It is designed to output combined data (abbreviated as LFO).

Further, the processing device 4 receives data (i.e. LR) in which the surface including a and b is larger than b and does not have a straight line along a from the classification device 2, and the data from the classification device 3 in which the surface including b and c is b. , c (i.e., F), data that is a combination of both (abbreviated as LRF) is received.
It also outputs data (i.e. LR) in which the plane containing a and b has a > b and does not have a straight line along a from the classification device 2, and outputs b,
When receiving data in which the surface including c has only a straight line portion along c (i.e. M), outputs data that combines both (abbreviated as LRM), and
Data from classification device 2 where the plane containing a and b has no straight line section along a where a>b (i.e. LR)
is received from the classification device 3, and the surface including b and c has elliptical data (i.e. R) with no straight line parts.
If it receives data that combines both (abbreviated as LRR), the classification device 2 outputs data where the plane including a and b has a > b and does not have a straight line along a (i.e. LR). When receiving and classifying data from the classification device 3 (ie, O) with a circular surface including b and c, data that is a combination of both (abbreviated as LRO) is output.

Further, the processing device 4 receives, for example, “3” from the classification device 2 as a regular polygon or similar data (i.e. N), and receives from the classification device 3 that the surface including b and c is a straight line portion. When receiving elliptical data (that is, R) that does not have a
Further, the classification device 2 accepts, for example, “4” as a regular polygon or similar data (i.e. N), and the classification device 3 accepts that the surface including b and c is along b and c, respectively. When data having a straight line part (i.e., F) is received, data that is a combination of both (abbreviated as 4F) is output, and the classification device 2 outputs data that includes a and b in a regular polygon or similar data (i.e., N ), and if the classification device 3 receives data (i.e. M) in which the plane including b and c only has a straight line along c, then outputs data that is a combination of both (abbreviated as 4M). In addition, the classification device 2 accepts, for example, “6” as a regular polygon or similar data (i.e. N), and the classification device 3 accepts “6” as the surface including b and c, respectively. When data that has a straight line along the line (i.e. F) is received, data that combines both (abbreviated as 6F) is output, and the classification device 2 outputs data that includes a regular polygon or similar data (abbreviated as 6F) including a and b. In other words, accept "6" as N),
When data (i.e. M) in which the plane including b and c has only a straight line along c is received from the classification device 3, data that is a combination of both (abbreviated as 6) is received from the classification device 3.
M) is output, and the classification device 2 outputs a square whose surface including a and b is a regular polygon or similar data (i.e. N), for example, a square shaped like a flower petal with each side protruding in an arc shape. If the classification device 3 receives data (i.e., F) in which the plane including b and c has a straight line portion along b and c, respectively, the data combining the two (abbreviated as ROU F) is output. It's becoming like that.

Therefore, if applied to, for example, tablet auditing, not only highly skilled pharmacists but also relatively inexperienced pharmacists can reliably identify tablets. This has excellent effects such as being able to significantly reduce the burden of tablet inspection work on pharmacists, especially highly skilled pharmacists.
