Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dental X-ray film package numbering device for assigning numbers to dental X-ray films.

[Conventional technology]

When taking an X-ray photograph of an affected area in dentistry, a dental X-ray film package is used. This will be explained with reference to FIGS. 3a and 3b.

FIG. 3a is a plan view of the dental X-ray film package, and FIG. 3b is a sectional view taken along line b--b in FIG. 3a. In the figure, 1 is dental X-ray film, 2
is a package that seals and stores the X-ray film 1.
The package 2 is made of a material that transmits X-rays but blocks light, such as an opaque thin synthetic resin sheet. 2a, 2b are both sides of the package 2, 2c, 2
d indicates the upper and lower bent portions of the package 2, and 2e indicates the overlapping portions of both ends of the package 2. Reference numeral 3 denotes an adhesive portion that adheres the overlapping sheets to each other in the overlapping portion 2e. By welding the front and back sheets at each side 2a, 2b and gluing the overlapping sheets together at the adhesive part 3, the X-ray film 1 can be attached to the packaging body 2.
sealed and shielded from external light.

When performing X-ray photography of the affected area of a tooth, first, the above-mentioned dental X-ray film package is brought into contact with the affected area in the oral cavity,
X-rays are irradiated from the side opposite to the side where the dental X-ray film package is held. As a result, an X-ray image of the affected area is captured on the X-ray film 1. When this X-ray photography is completed, the dental X-ray film package is taken out from inside the oral cavity, and a developer is injected into the package 2 with a syringe or the like to perform development.
After removing the developer, a fixer is injected to perform fixing. After the above processing is completed, by peeling off the package 2 and taking out the X-ray film 1, an X-ray film 1 (X-ray photograph) on which an X-ray image of the affected area is taken can be obtained.

Incidentally, such X-ray imaging is performed not only on one patient but on many patients, and in many cases, multiple X-ray imaging is performed on one patient. Therefore, it is necessary for dentists to distinguish these X-ray films by patient, by affected area, etc.
In order to make this distinction, means are employed for assigning a specific number to each X-ray film. In this way, a number sheet is used to assign a specific number to the X-ray film 1. This will be explained with reference to FIG.

FIG. 4 is a plan view of a dental X-ray film package to which a number sheet is attached. In the figure, the same parts as those shown in FIG. 3a are given the same reference numerals.
5 is a number sheet affixed to the corner of the dental X-ray film package 2. In the illustrated case, the number sheet 5 has the number "50" formed of a material that does not transmit X-rays. Therefore, when this dental X-ray film package is irradiated with X-rays during X-ray photography,
The number "50" is photographed at the lower right corner of the X-ray film 1 after the development and fixing processes have been completed.

Next, details of the number sheet 5 will be explained. FIG. 5a is a plan view of the number sheet, and FIG. 5b is a sectional view taken along line b-Vb in FIG. 5a. In the figure, 6
is a transparent sheet, for example, a synthetic resin material is used. Reference numeral 7 is ink that is applied by printing or the like to the back surface of the sheet 6, and the number is displayed using this ink 7. The ink 7 is made of a material that does not transmit X-rays, such as ordinary pigment mixed with an appropriate amount of lead powder. 8 is an adhesive layer applied to the back surface of the sheet 6, and 9 is a release paper attached to the adhesive layer 8.

Such a number sheet 5 is affixed to the surface of the dental X-ray film package (the lower right end in FIG. 4) with the release paper 9 peeled off prior to the X-ray imaging. When X-ray photography is performed after that, the ink 7 formed on the number sheet 5 does not transmit X-rays, so the number ("50" in the figure) is taken on the X-ray film 1 together with the X-ray image of the tooth. will be done. By associating this number with a specific patient, the X-ray film that has been taken can be distinguished by patient, by affected area, etc. In addition, lead-containing ink7
is printed on the bottom surface of the sheet 6 and is not exposed on the surface, so even if the dental X-ray film package to which this number sheet 5 is attached is placed in the oral cavity, the patient will not be harmed by lead.

[Problem that the invention attempts to solve]

By the way, the size of the above-mentioned dental X-ray film package is very small compared to the size of general X-ray film because it is inserted into the oral cavity.
It is made to approximately 45mm x 33mm. The number sheet 5 is also small accordingly, for example, 7mm x 7mm.
That's about it. Therefore, it is very difficult to take out the dental X-ray film packages one by one from the storage location and then peel off the small number sheet 5 as described above from the release paper 9 and stick it to a predetermined location. However, the drawback was that it required careful attention and a considerable amount of time and effort.

The purpose of the present invention is to eliminate the drawbacks of the above-mentioned prior art,
To provide a number attaching device for a dental X-ray film package capable of automatically attaching a number sheet when taking out the dental X-ray film package from a storage location without requiring any effort or time. be.

Next, the operation of this embodiment will be explained with reference to FIGS. 2a, b, and c. When the first drive wheel 14 is rotated once by the handle 14b, this rotation is caused by the rotation of the gear 14.
It is transmitted to the second drive wheel 15 via the chain CH and the gear 15a, causing it to rotate once. This rotation causes the pin 15b to move to the position at the start of rotation.
From P ₁ , through position P ₂ and back again to position P ₁ . pin 1
5b moves from the position P ₁ to the position P ₂ , the take-out table 13 is moved to the left by the connecting rod 16 mounted on the pin 15b, and when the pin 15b reaches the position P ₂ , it moves to the position shown in FIG. 2a. The state shown is as shown, and the extraction platform 1
The supporting portion 13a of No. 3 is removed from the container 11, and the container 11
The take-out portion 13b of the take-out table 13 is opposed to the lower part of the take-out table 13. Therefore, the film package 12n stored at the lowermost end of the container 11 is removed from the take-out section 1.
It falls onto 3b. At this time, the surface of the take-out portion 13b and the surface of the support portion 13a are approximately the same as that of the film package 1.
Since the difference is only in the thickness of film packaging body 1.
The film package 12n _-1 next to the film package 2n is placed on the film package 12n, and its lower surface is flush with the support portion 13a. Then, while the pin 15b moves from the position _P2 to the original position _P1 again, the take-out table 13 now moves to the right in the figure, and the support part 13a
enters the lower part of the container 11, and the pin 15b is in position.
When P ₁ is reached, the state returns to the original state shown in FIG.

During the above operation, the rotation of the first drive wheel 14 or the rotation of the second drive wheel 15 is transmitted to the transfer roller 17, tension roller 27, pressure roller 28, etc. by a drive transmission means (not shown). and rotate these by a predetermined number of rotations. Therefore, the release tape 20 is moved a predetermined distance. In addition, although it is desirable that the drive transmission means be constituted by a gear mechanism in order to accurately rotate each part, other mechanisms may also be employed.

As described above, when the first drive wheel 14 completes one rotation, the take-out table 13 returns to its original position as shown in FIG. The paper is taken out upward and is sandwiched between the transfer rollers 17.

Next, the first drive wheel 1 is moved again by the handle 14b.
4 rotates once, the take-out table 13 reciprocates as described above and takes out the next film package 12n _-1 onto the take-out portion 13b. On the other hand, the film package 12n that has already been taken out is transferred to the right in the figure by this one rotation. That is, when the first drive wheel 14 rotates once, a drive transmission means (not shown) is driven, and the transfer roller 17 and the pressure roller 28 rotate at a predetermined rotational speed. Therefore, the film package 12n, which has been clamped by the transfer roller 17 due to the previous operation, is transferred to the right at a speed corresponding to the rotational speed of the transfer roller 17, and is slid on the support base 18 while being transferred to the press roller 28. sandwiched between. At this time,
Since the pressure roller 28 is also rotating, the film package 12n is further sent to the right and the pressure roller 28 is rotated.
8 and falls into the receiving part 29. As a result, the film package 12n is taken out of the container 11 by the first rotation of the first driving wheel 14, and is transferred and dropped into the receiving portion 29 by the next rotation.

By the way, as described above, the rotation of the first drive wheel 14 is also transmitted to the tension roller 27 by the drive transmission mechanism, causing it to rotate at a predetermined speed. As a result, the release tape 20 is pulled out from the roll 22 by a length corresponding to the number of rotations of the tension roller 27. Then, as the release tape 20 passes through the separation column 26, the number sheet 5 is separated from the release tape 20 as described above. This release tape 20
The pulling-out operation is performed at the same time as the film package 12n is transferred to the right. In this case, the time point at which the number sheet 5 is separated from the release tape 20 is
The drive transmission means adjusts the location where the number sheet 5 of the film package 12n is to be attached to coincide with the point in time when the tip 26c of the separating column 26 passes. Therefore, the number sheet 5 separated from the release tape 20n is attached to the transferred film package 12.
n is pressed onto a predetermined location by a pressing roller 28, as shown in FIG. 2c, and adhered by the adhesive layer 8. Therefore, the film package 12n with the number attached thereto is transferred to the receiving portion 29. Thereafter, by the same operation, a film package with a number attached every rotation of the first drive wheel 14 can be obtained.

In this way, in this embodiment, the first drive wheel is
The numbered film package can be taken out from the container simply by rotating it.

Note that what is displayed on the number sheet is not limited to numbers, but may also be letters, symbols, etc., or a combination of these.
It is also possible to connect a motor to the second drive wheel, and drive the motor to rotate the second drive wheel once each time the switch is closed. Furthermore, the entire device is
If it is stored in a transparent case made of line-opaque material,
Even when the device is placed near the location where X-ray photography is performed, the X-ray film can be protected, the film package and the number sheet can be stored together, and the number sheet can be It will also be possible to observe the state of attachment and the remaining amount of film packaging and number sheets. Furthermore, the transfer roller can be omitted by positioning the separating column and the pressing roller closer to the tip of the take-out portion of the take-out table.

〔Effect of the invention〕

As described above, in the present invention, the take-out stand is driven to take out the film packages one by one from the container, and during the transfer, the number sheet separated from the release tape by the separation column is attached. The numbered film package can be taken out with just one action of taking out the film package from the container without requiring any effort or time.
