Description

[Detailed explanation of the device] This device simultaneously fills multiple holes with powder and granules, and simultaneously compresses the tablets using a pair of upper and lower pins that correspond to each hole. This invention relates to a means for filling the holes in a tablet machine with powder and granules, and its purpose is to provide a means for compressing a plurality of tablets without any variation.

FIG. 1 shows a conventional reciprocating stroke filling type tablet press.

That is, in this reciprocating stroke filling type tablet press, a filling tool C intermittently slides relative to a bellow (d) bored through a plurality of holes e, and the filling tool C is inserted through a flexible tube. Connected to hopper a.

This filling tool C is a box with an open bottom, and when the filling tool C slides back and forth on the surface of the bed d by power, when the filling tool C moves forward, a hole is inserted into the bed d from the open bottom. The holes are filled with eK powder.

In order to improve the production efficiency of tablets, the number of holes e is made plural,
It is extremely difficult to equalize the filling amount because all of these holes are filled at the same time, so this type of tablet machine with multiple holes is especially useful for making uniform amounts of tablets for pharmaceuticals and other products. It cannot be used in the field where it is required.

When filling multiple holes eVC at the same time from the above-mentioned filling tool C, the filling amount becomes uneven because there is a large amount of powder in the hopper a and the filling tool c, which causes a bridging phenomenon between particles. In addition, the accumulation pressure of particles on the open bottom surface of the filling tool C is uneven depending on the location, and the classification effect due to the back and forth stroke of the filling tool C also affects the unevenness.

This invention eliminates the disadvantages of simultaneously filling multiple holes in the conventional tablet press as described above, and provides a means for evenly filling those holes. This invention will be explained by an example.

An embodiment of this invention is shown in FIGS. 2 and 3, and the features of this invention include that the filling tool intermittently slides relative to the bed 7 bored through the hole 1, and It is different from the conventional tableting machine described above in that the slotted hole 1 is simultaneously filled at the first relative position where the tool engages with the slotted hole, and the tablet is compressed at the second relative position where the filling tool leaves the slotted hole. The same is true.

4 is a horizontal sliding toy in this invention, and hopper 6
so that it can receive powder and granular material and flow out two small amounts continuously.
It is driven by a suitable power such as a motor 42.

When the vibration direction includes both a front-rear component and a left-right component, it is more effective to equalize the fineness of the powder in the width direction of the vibrating toy 4.

Reference numeral 5 denotes a composite toy according to this invention, in which individually divided vertical toys 51 are arranged in parallel.

Each vertical toy 51 corresponds to each hole 1Vc bored in the bed 7, respectively.

The socket 52 of the composite toy 5 is arranged below and opposite to the outlet 41 of the vibrating toy 4.

Reference numeral 8 denotes a powder filling tool in this invention, which consists of a plate with a plurality of supply holes 81 provided corresponding to the slotted holes 1, and is similar to the filling tool of the conventional tablet press described above. , can be slid back and forth on the bed 7.

The supply holes 81 are connected to the respective vertical toys 51 via flexible tubes 53.

FIGS. 2 and 3 show the retracted position of the filling tool 8. In this position, the powder and granules that have been filled into each of the holes 1 are compressed into tablets by the upper and lower pins 2 and 3. Ru.

In addition, in the forward position (not shown) of the filling tool 8, the supply hole 81 engages with the slotted hole IK, and the powder and granules entering the supply hole 81 are sucked into the slotted hole IK when the lower barrel 3 descends. is filled with.

That is, the forward position in this example is the first relative position between the filling tool 8 and the propeller 7, and filling is performed at this position.

Further, the retracted position in the above example is also the second relative position, and tableting is performed at this position.

In addition, according to another embodiment not shown, the filling tool 8
The relative intermittent sliding between and bet I can be achieved by other means.

That is, contrary to the embodiment described above, the position of the filling tool 8 is fixed, and the bed I is moved intermittently.

What is most suitable for this purpose is a design in which the bed I is a turret disk with a mechanism that rotates intermittently horizontally, and the filling position of the slotted hole 1 and the tableting position by the upper and lower pins 2 and 3 are separated. is possible.

Such tabletting by rotating the bed turret is known for individual tablet presses.

Now, as mentioned above, this idea consists of paralleling one horizontal vibrating toy 4 that continuously flows powder and granules in small quantities, and the vertical toy 51 that is individually divided according to the plurality of holes 1. Since the socket 52 of the composite toy 5 is disposed opposite to the outlet 41 of the vibrating toy 4, the powder and granules flow out from the outlet 41 of the vibrating toy 4 along the width of its mouth. On average, the water flows down to the socket 52 of the composite toy.

Since the sockets 52 of the composite toy are arranged in a row, the amount of powder and granular material supplied to each vertical toy 5 is approximately equal, and therefore, at the second relative position between the bed 7 and the filling tool 8. During a certain retraction of the filling tool 8, the supply hole 81 closes on the surface of the bed 7, and powder is therefore accumulated in each vertical toy 5.

In order to prevent this accumulated amount from becoming excessive, it is preferable to provide a mechanism (not shown) that adjusts the amount flowing from the hopper 6 to the vibrating toy 4 to an appropriate amount.

As mentioned above, the powder and granules accumulated between the vertical toy 51 and the supply hole 811 during the non-filling period are almost constant in density, and the density is almost constant, even though it cannot be said to be absolutely uniform. The heights are also approximately the same.

Therefore, since the amount of powder and granular material filled into each hole 1 during the above-mentioned filling period is substantially equal, there is almost no variation in the tableted molded product.

Thus, according to this invention, a plurality of uniform tablets can be obtained in each tableting process, so pharmaceuticals, other products, etc.
Production efficiency can be significantly improved in the field of tablet production, where uniformity of tablet quantities is particularly required.
