Description

Detailed Description of the Invention (Field of Industrial Application) This invention is a rotary cored tablet for producing cored tablets for pharmaceuticals, etc., which can determine the presence or absence of cored tablets and completely eliminate non-core tablets. It concerns tablet machines.

(Prior art) Generally, in order to manufacture dry-coated tablets used for pharmaceuticals, etc., a first powder is placed in a large number of dies arranged on a rotary disk, and then a small tablet is placed on top of the powder. After filling the core tablet with a second powder to the length of 15 mm, the core tablet is compressed with an upper punch and a lower punch to form a cored tablet as a molded product. It comes out.

In the past, it was impossible to confirm that the core lock was fed into the mortar at all, but if you tried to confirm it,
After taking out the dry-coated tablets as a product from the tablet machine, all of them must be sorted to determine whether there are any non-coated tablets, based on weight differences, etc. In addition, the size of the tablets tends to become smaller; Since it is impossible to sort out the difference in weight, etc., the present invention is effective because it allows the core tablets placed in the mortar to be directly confirmed.

(Problems to be Solved by the Invention) In dry-coated tablets used for medicine, etc., the vertical and circumferential portions of the tablet are made of different types of drugs, and when the tablet is taken, two or more locations in the body may be affected. However, in a rotary dry-coated tablet machine that manufactures dry-coated tablets, it is necessary to supply a tangent into the mortar of a rotary disk that rotates at high speed, and the method for doing so is as follows: A circular plate with a large number of holes that synchronizes with the rotary disk is held vertically in advance, and the lock is dropped into the upper part of the mortar.

However, when the rotary cored tablet machine stops, the tangential edge pops out of the hole in the disc due to inertia, which indicates that the tangential edge is previously held in the hole in the disk. This may occur even after confirmation by, etc., and there is a risk that K, which has not actually been fed into the mortar, may be treated as a normal dry-coated tablet.

Unfortunately, due to the scratches on the IL lock and the effects of static electricity, the tangent that had been supplied to the disk in advance was not properly fed into the mortar, that is, it was not fed at all, and the timing of the feed was out of order, causing the contact. The vertical part is broken and pops out of the case, and such vertical force; if the unattached vertical part is mixed into the product, a dry-coated tablet, it is absolutely impossible to buy the dry-coated tablet. There was a moment when I had to do something.

(Means for Solving the Problems) In order to solve such problems, the configuration of the present invention is as follows.
Put the seventh powder (5) into the mortar hole of the mortar (2) installed in the rotating gl, and place 1 of the powder (7) vertically on top of the powder (5a).
! Place the second powder (5b) so as to cover the tangent (7).
) is filled and then compressed by an upper punch (17) and a lower punch (3) to produce a dry-coated tablet uD. After placing the powder (7) and before filling the second powder (5b), a color-specific sensor (4) is installed, and the color-specific sensor (■) detects the color difference between the powder (5a) and the tangent (7). This rotary tablet machine with tablets is characterized in that it detects the presence or absence of the clasp (7) and rejects tablets without a core.

(effect) The above technical means works as follows.

The mortar (2) containing the first powder (5a) and the K core vertical (7) are supplied or placed, and then the rotary disk (1) is rotated to supply the second powder (5b). However, the second powder (
At the position before powder 5b) is supplied, the color difference between the powder (5a) and the tangent (7) is determined by the color sensor 1fiK, and if there is a predetermined color difference, it is recognized as normal, and if the tangent is If it is not placed, the color difference is not present, so it is recognized and memorized as having no tangent, and it is discharged as a defective product separately from the good printed core tablets.

In addition, the color-coded sensor (4) feeds the powder in synchronization with the rotating mortar (2), even if the powder used for the vertical grinding (7) and the powder initially put into the mortar (2) are of the same color. Even if it happens, the color difference can be detected instantaneously because the tablets compressed with the vertical t'/)K are a little darker in color.

(Example) If an example of this invention is shown in the drawings and customs is carried out, (1)
is a rotary disk on which a large number of dies (2) are arranged at equal intervals on the circumference.

(6) is a lock-breaking supply disk synchronized with the rotary disk (69) for feeding the broken lock (7) into the hole of the mortar (2).
The lock-breaking supply disc (6) holds in its hole in advance the tangential length (7) sent from the feeder @ through the feeding pipe u3, and the tangential length (l) is held. It is detected by the broken lock detection phototube Uω, and if this tangent (7) is not held, the signal from the timing phototube u51 and the timing hole Um is memorized.
This vertical position of the die (2) is memorized, and the non-nucleated tablet is ejected into the vertical chute (c) by the removal damper u&.

(5a) is the first powder that is put into the hole of the mortar (2), and the powder (5a) melts down from the powder droplet U mark and is quantitatively determined by the first feeder (4). can be fed into the mortar (2).

(5) The first powder (5a) is put into the hole of the mortar (2), then one core tablet (°l) is supplied, and then the second powder (811c) is filled. This is the second powder.

(3) The lower punch, Uη is the upper punch, and (9) is the compression roll for vertically compressing the lower punch (8) and the upper punch υη.

till is a dry-coated tablet that is normally formed with a vertical axis (7), and the dry-coated tablet 11 is taken out of the rotary disk (1) by a damper uO) and a shoe)01). It falls into the Ude (support).

The circle is a color-coded sensor disposed at a position between 1, which is filled with the powder of the rear node 2, which is supplied with the vertical axis t'/J, and the color-coded sensor outputs a color-coded signal. Detection unit that sends and receives signals (

and a stabilized power supply (#i).

This color-coded sensor (A) normally
) is filled with the first powder (5a), and then the tangential and vertical holes ('
l) is fed by the tablet-breaking supply disc (6) onto the powder (5a), i.e., by illuminating the powder (5a) in the mortar (2) with a color-coded signal. It is determined based on the color difference between the tangent and vertical (7), and it recognizes that the tangent and vertical (7) are supplied. If the tangent and vertical (7) are not placed, there is no color difference. It is determined that the tangent (°7) is not supplied, and the memory device (2) K is stored.

Then, this non-tangential vertical chute is operated by operating the solenoid connected to the storage device (2), which activates the exclusion damper u81, and the non-tangential vertical chute (to) operates the rotary disk (
1) It can be excluded outside.

(Effect of light power) As explained above, Raikou (7) uses color-coded sensors to directly detect the inside of the mortar after the feeding process in which the tangent is supplied into the mortar of the rotary disk. It is possible to determine the presence or absence of a tangent by using the method, and since it can completely eliminate ungrafted grains, there is no need for any other device to separate the grainless grains from the hard-coated tablets. This has the effect of enabling quality control, which is important due to the nature of dry-coated tablets used for medicines, etc., which require no additional processing.
