Description

Detailed Description of the Invention (Field of Industrial Application) This invention provides a method for supplying core tablets to the mortar hole of a rotary core tablet machine for producing core tablets for pharmaceuticals, etc. The present invention relates to a core tablet supply position adjusting device for a rotary core tablet machine that can adjust the supply position even during operation of the tablet machine.

(Prior art) Generally, in order to manufacture dry-coated tablets used for pharmaceuticals, etc., a first powder is placed in a number of dies arranged on a rotary disk, and then a cored tablet is placed on top of the powder. The core tablet is fed or placed by a core tablet feeding device, and after the second powder is further filled from above the core tablet, it is compressed with an upper punch and a lower punch to obtain a cored tablet as a molded product.

However, in such a rotary core tablet machine, the core tablet must be fed into the mortar of a rotary disk that rotates at high speed, and moreover, it must be fed to the center of the mortar. be.

Therefore, conventionally, the core lock supply device holds the core locks in advance in a disk having many holes that synchronizes with the rotary disk, and drops the held core locks one by one from above the mortar. However, the feeding position into the mortar cannot be adjusted at all while the tablet machine is in operation; by changing the installation position of the core tablet feeding device while the tablet machine is slightly stopped, It could only be adjusted in the circumferential direction.

(Problems to be Solved by the Invention) In a core tablet used for medicine, etc., the core tablet and the surrounding tablet portion are made of different types of drugs, and when the core tablet is taken, two or more locations in the body may be affected. However, if the core tablet is not located at the center of the tablet part and the core tablet is eccentric,
These tablets have important problems due to the nature of dry-coated tablets, such as changes in the temporal action when taken and the possibility of cracking.

In other words, in recent years, rotary core tablet machines that manufacture such core tablets have been becoming faster and faster, and the types of core tablets in terms of properties and sizes have also become more diverse. It is difficult to adjust the supply of tablets to the center of the die while the tablet machine is stopped, assuming that the tablet machine is in operation, and the supply position changes even while the tablet machine is in operation. There was a problem in that the position had to be adjusted easily and reliably even during operation.

(Means for Solving the Problems) In order to solve such problems, the configuration of the present invention is such that the first powder 26a is put into the mortar hole of the mortar 2 disposed on the rotary disk 1, and the first powder 26a is The core tablet 14 previously held on the disc 13 is supplied onto the powder 26a, and the second powder 26b is filled so as to cover the core tablet 14, and then compressed with the upper punch and the lower punch 3. A rotary dry-coated tablet machine for producing dry-coated tablets includes: a drive gear 4 that rotates together with a rotary disk 1; a first gear 5 that meshes with the drive gear 4 and is rotatably attached to a first shaft 8; ,
A second gear 6 is rotatably attached to a second shaft 9 which meshes with the first gear 5 and is arranged to be swingable from the first shaft 8; 1st axis 8
A disk gear 7 is attached to a rotatable disk shaft 10 which is arranged to be more swingable and is arranged on an extension of a straight line connecting the first shaft 8 and the second shaft 9.
and a disk 13 attached to the disk shaft 10.
A rotary core tablet machine characterized in that the supply position of the core tablet 14 supplied from the die to the mortar hole of the mortar 2 can be adjusted by swinging the second shaft 9 and the disc shaft 10, respectively. This is a nuclear lock supply position adjustment device.

In the above configuration, each gear 4, 5,
6 and 7 may be spur gears, helical gears, or a combination thereof.

(effect) The above technical means works as follows.

First, the rotation of the driving gear 4 that rotates together with the rotary disk 1 is sequentially transmitted to the first gear 5, the second gear 6, and the disc gear 7, and the core lock is held in advance on the disc 13, which is a core lock supply device. 14 is automatically supplied by falling in synchronization with the mortar hole of the rotating mortar 2.

Therefore, if the condition of the supply position of the core tablet before being filled with the second powder is inspected using a stroboscope or the like during destructive inspection of the core tablet, which is a molded product, or during operation, if the core tablet is in the center of the mortar. If it is determined that the position is not located, move the first connecting plate 11 to the circumferential adjustment handle 17
etc., the second shaft 9 swings about the first shaft 8 and is attached to the second gear 6 and the disk shaft 10, which are rotatably attached to the second shaft 9. The meshing of the disc gear 7 changes around the disc axis 10, and the feeding position of the core lock 14 held on the disc 13 can be adjusted in the circumferential direction of the disc 13. That is, it can be adjusted in the circumferential direction of the rotary disk 1.

In addition, the second connecting plate 12 is
etc., the disc shaft 10 swings around the first shaft 8, and the engagement between the second gear 6 and the disc gear 7 is as follows.
Since the core lock 14 is moved toward the center of the rotary disk 1, the supply position of the core lock 14 can be adjusted in the front and rear directions of the rotary disk 1, that is, in the direction of the center line.

Each of the above adjustments requires only a small adjustment range because the hole diameter of the die 2 is relatively small. Since the adjustment operation can be performed independently of the rotating gears, etc., the position can be adjusted even while the tablet machine is in operation.
