## Abstract

The invention relates to a method for inserting inserts (cores) into female molds of a rotary tableting press. The inserts are inserted individually into one female mold each of a rotating rotor of the rotary tableting press by separating the inserts from a nonspecific quantity by means of a feeder mechanism, feeding them to a core distributor and aligning them from there with the female molds in a precisely defined position and delivering the inserts to the female molds in this position.

## Claims

### Claim 1

A method for inserting inserts into female molds of a rotary tableting press, whereby the inserts are inserted individually into one female mold each of a rotating rotor of the rotary tableting press, the method comprising:
separating the cores by means of a feeder mechanism from a nonspecific quantity,
feeding them to a core distributor and directing them from there into the female molds in a precisely definable position and
depositing the inserts in the female molds in this position.

### Claim 2

A device for inserting inserts into female molds in a rotary tableting press, having a feeder mechanism by means of which the single-fed inserts are brought into alignment with a female mold of the rotary tableting press, wherein the feeder mechanism comprises a core distributor; the core distributor has a drivable rotor comprising over its circumference at least one core receptacle; and a path of movement of the core distributor of at least one core receptacle and a path of movement of the female molds of the rotary tableting press intersect in a partial circle, whereby the at least one core receptacle comprises restraining means which allow holding of the inserts, conveyance of the inserts and delivery of the inserts.

### Claim 3 (depends on 2)

The device according to claim 2, wherein the core receptacle comprises gripper elements for receiving the inserts, for centering the inserts, for conveying the inserts and for ejecting the inserts.

### Claim 4 (depends on 2)

The device according to claim 2, wherein the gripper elements are pneumatically controllable.

### Claim 5 (depends on 2)

The device according to claim 2, wherein the core distributor comprises a pneumatic connection, which is operatively connected to valves controlling the gripper elements.

### Claim 6 (depends on 2)

The device according to claim 2, wherein the valves can be controlled by a stationary control cam of the core distributor.

### Claim 7 (depends on 2)

The device according to claim 2, wherein four valves are assigned to each gripper element for opening or closing gripper tongs and for receiving and ejecting the inserts.

### Claim 8 (depends on 2)

The device according to claim 2, wherein the rotor of the core distributor can be driven by a controllable drive.

### Claim 9 (depends on 8)

The device according to claim 8, wherein the rotor is drivable by a stepping motor.

### Claim 10 (depends on 2)

The device according to claim 2, wherein the feeder mechanism comprises a core feeder mechanism which together with the core separator and the core distributor forms a feeder chain for the inserts.

### Claim 11 (depends on 2)

The device according to claim 2, wherein the core feeder mechanism comprises a rotary conveyor which supplies the inserts individually to the core distributor in a defined manner.

### Claim 12 (depends on 11)

The device according to claim 11, wherein the conveyor has positioning pockets for self-positioning of the single-fed inserts.
