Furthermore, when there are a plurality of types of elements to be inserted into the card material 1, there is a drawback that the work of inserting the element sheet 4 into the card material 1 becomes complicated.

The present invention eliminates the drawbacks of the prior art as described above.

Embodiments of the present invention will be described below with reference to FIGS. 7 to 12.

First, the present invention will be explained in detail based on the block diagram of FIG.

36 is a card 1 driving track, 1 is a card material, 37 is a supply means for card material 1, 11 is a base tape, 8 is a cover tape, 38 is a forming means for forming the dome 9 on the cover tape 8, 39 is a base A driving means for the tape 11 and the cover tape 8; 40 a tape punching and inserting means for punching out the base tape 11 and the cover tape 8 and inserting them into the card material 1; 6 a fixing ring; 41 a supply means for the fixing ring 6; 42 is the fixing ring 6 attached to the card material 1
43 is a tightening means for tightening the fixing ring 6; 44 is a means for ejecting the completed element card I from the device; After the card material 1 is supplied, the base tape 11 and cover tape 8 are punched out and fixed in the element insertion hole 2. Next, the fixing ring 6 is press-fitted and fixed, and finally the completed element card 7 is formed. The process of ejecting is repeated, and element cards 7 are continuously manufactured.

The above is the general configuration of the device card manufacturing apparatus for a thermoluminescent dosimeter of the present invention, and next, the specific configuration of the apparatus will be explained based on FIGS. 8 to 12.

45 is a supply reel for the cover tape 8, 46 is a supply reel for the base tape 11, and 47 is a supply reel for the cover tape 8 and the dome 9.
48 is a molding die; 49 is a sprocket in which sprocket pins that engage with sprocket holes 10 of the cover tape 8 are implanted on the circumference in order to drive the formed cover tape 8; is a wheel,
Arrows B and C indicate the tape feeding direction.

Reference numeral 50 denotes a plurality of card materials 1, which are supplied by the card material 1 supplying means 37 onto the card drive track 36 (above A-A' in FIG. 8).

51 is a punching punch for punching out the base tape 11 and cover tape 8 in an overlapping manner; 52 is a punching die;
Since the punch 51 is inserted into the hole up to the lower end of the punch die 52, a relief portion 53 is provided below.

54 is a press-fitting punch, and a plurality of fixing rings 6 are stacked.
The fixing rings 6 supplied one by one by the fixing ring supplying means 41 are hot press-fitted into the element insertion hole 2 from below.

Reference numeral 55 denotes a constriction punch, which tightens approximately the center of the fixing ring 6 to firmly fix the fixing ring 6.

A sprocket wheel 56 is driven simultaneously with the base tape 11 and the cover tape 8 stacked on top of each other, and sprocket pins that engage with the sprocket holes 10 of both tapes 8 and 11 are provided on the circumference.

Next, the operation will be explained.

First, a plurality of stacked card materials 1 are supplied onto the card drive track 36 as shown by the arrow.

The supplied card material 1 is transferred below the punching die 52, the punch 51 descends in the direction of arrow G, and the cover tape 8 and base tape 11 are simultaneously punched out.
is inserted into the element insertion hole 2.

At this time, for each punching, the forming punch 47 moves once to the arrow F.
The sprocket wheel 49 is lowered as shown in FIG.
drives both tapes 8 and 11 one pitch.

Such an operation is repeated, and the element sheet 4 and the cap sheet 5 are sequentially inserted into the element insertion hole 2.

After the insertion is completed, the card material 1 is driven below the press-fitting means 42 of the fixing ring 6, and the lower one of the stacked fixing rings 6 is pushed over the element insertion hole 2 as shown by arrow E. Then, the press-fitting punch 54 descends as shown by arrow H to hot-press-fit the element sheet 4° and the cap sheet 5.

When the heat press-fitting of the fixing ring 6 is completed, the card material 1 is transferred to a position below the shark punch 55, and the shark punch 55 descends as shown by the arrow (2), thereby tightening the fixing ring 6.

This improves the sealing properties of the thermoluminescent element 3 and the fixing properties of the fixing ring 6.

After that, the element card 7 is sent again from the J position and is ejected from the card drive track 36 by the ejecting means 44 in the direction of, for example, by an air cylinder or a spring (not shown).

As described above, the element cards 7 are manufactured one after another.

In the explanation of the configuration, the tape supply and punching means are explained in one row, but when the inoculation element tape is incorporated into one card material 1, the tape supply and punching means can be arranged in multiple rows. It is possible to implement.

Further, in the present invention, the element card 7 having four element insertion holes 2 has been described, but the configuration of the element card 7 and the number of element insertion holes 2 can be easily changed.

Since the device card manufacturing apparatus for a thermoluminescent dosimeter according to the present invention is configured as described above, it has the following effects.

(1) Element cards for thermofluorescent dosimeters can be manufactured continuously in a single hour.

(2) Mechanization reduces the variation in measured values due to the adhesion of oil and dust to the sheet during manual manufacturing, improving the measurement accuracy and reliability of thermoluminescent elements.

(3) Element card manufacturing that requires various manufacturing processes,
By adopting a punching and inserting method in which tapes are overlapped and inserted into a punched card material, the number of processes can be reduced and the product can be made more compact.

(4) The complexity of work caused by an increase in the number of element types can be eliminated.

As described above, the present invention has various advantages and is of great industrial value.
