Definitions
- the invention relates to a process for the production of pharmaceutical tablets, in which tablet pellets are pressed and provided with a coating, and a system for carrying out the method.
- a generic method and systems for carrying out the method are known from practice.
- the tablet pellets are removed immediately after the pressing process a coater to provide the pellets with the coating.
- This product-specific properties of compacts can not be considered, which can cause quality defects in the tablets produced.
- the object of the invention is to provide a method and a system for carrying out the method with which high-quality tablets can be produced.
- This object is achieved by a method in which the tablet pressings, before they are provided with the coating, are stored for a product-specific curing time in an intermediate storage and are then automatically removed from the intermediate storage for further processing.
- a system controller in which product-specific curing times are stored or can be stored, records the time of introduction of the tablet compacts into the intermediate store and, after the curing time has elapsed, causes the automatic removal of the tablet tenpresslinge.
- tablet compacts can still be relatively unstable after being pressed and / or undergo dimensional changes due to expansion or shrinkage. This poses a problem for continuous or quasi-continuous production of pharmaceutical tablets in which the tablet compacts are to be coated after being pressed. On the one hand, these tablet compacts can not yet be sufficiently stable after being pressed for further processing, so that they break or even completely disintegrate. On the other hand, after they have been coated, the tablet compacts could experience expansion or shrinkage. If the changes in the dimensions of the tablet pellets which form the tablet core in the coated pharmaceutical tablets are greater than the change which can be compensated for by the elasticity of the coating, cracks may form in the coating. Such cracks are particularly problematic in functional coatings, which are intended to release an active ingredient of the tablet, for example, only in the small intestine instead of in the stomach of a living being to be treated.
- the tablet pellets are stored for a curing time in an intermediate storage facility.
- the tablet pellets can be completely cure dig. They reach their final size and then have the necessary mechanical strength.
- the necessary curing time can be a few minutes to several hours. The curing times are thus product-specific.
- the tablet pellets are removed from the interim storage and fed to further processing. This takes place automatically controlled by a plant control.
- the product-specific curing times are stored or entered there. Furthermore, it is conceivable that the originally deposited curing times for a specific product are changed as part of an adaptation or optimization.
- the system controller records the time of insertion of the tablet pellets into the interim storage facility and initiates the automatic removal of the tablet pellets at the end of the curing time. In this case, and / or plant-specific operating parameters such as occupancy condition coater, occupancy status intermediate storage and the like. Be taken into account.
- tablet pellets are spent with matching curing time in a container and the container transferred by a handling system in the intermediate storage.
- the summary of tablet compacts with consistent curing time in a container simplifies the process. Thus, it is not necessary to keep track of the curing time of the individual tablets, but it can be a common curing time for the tablet compacts are kept in a container in the plant control.
- the automatic transfer of tablet pellets to the intermediate storage facility as well as the automatic removal are also facilitated if the tablets are combined in one container.
- An automatic handling system can thus be optimized for the handling of a defined object, here a container.
- the method provides that the container is transferred to one of at least two storage bins in the intermediate storage, wherein the system control detects the container contents and the parking space in the interim storage. After expiry of the stored product-specific curing time of the container, controlled by the plant control, automatically removed from the handling system from its parking space in the interim storage.
- the fact that the container contents and the parking space of a container is recorded in the intermediate storage in the plant control several containers can be stored in a temporary storage.
- the necessary size of the intermediate storage results from the speed with which the tablet pellets are pressed, or the speed with which the tablet pellets are provided with a coating, as well as the product-specific curing time.
- the container taken from the intermediate storage is docked to an inlet opening of a coater and the tablet pellets are emptied from the container into the coater.
- emptying a container into a coaster can also be done automatically.
- tablet pressings with different curing time are stored in the intermediate storage at the same time.
- the method enables the processing of different types of tablet pellets. In each case those compacts whose curing time has expired, removed from the warehouse and fed to the subsequent processing. On the one hand, this increases the flexibility and, on the other hand, the utilization of a corresponding process or a system implementing the process. This is particularly valuable when different products are to be manufactured and there is a change.
- tablets of a product are still present in the interim storage in the interim storage, while already pressed tablet pellets for another type of tablets and also stored in the interim storage. Furthermore, this is advantageous if a plurality of tablet presses and / or a plurality of coaters is assigned a common intermediate storage. Particularly advantageous are the different tablet pellets for different lengths of curing in the interim storage.
- the preparation of tablet pressings is at least partially continuous.
- the pressing of the tablets can take place continuously or, on the other hand, the coating of the tablet compacts with a coating. It is also possible that both pressing and coating with a coating are continuous. This applies at least until it comes to a change of the corresponding product to be processed when pressing the tablets or when providing the tablet pellets with a coating.
- a dedusting of the tablet pellets takes place. This makes it easier to reliably provide the tablets with a coating. Furthermore, dedusting the tablet pellets prevents dust from causing defects in the coating.
- the object is further achieved by a plant for the production of pharmaceutical tablets, wherein the plant has containers which are set up for receiving the tablet presses issued from the tablet press.
- the system comprises an intermediate storage facility with at least two storage locations, a handling system which transports the containers into the intermediate storage facility and a system control system controlling the handling system, product-specific curing times being storable or deposited in the facility control system and the facility control unit storing the content of a container detects a container in the storage facility assigned storage space and the beginning of the curing time and after the curing time, the handling system for removal of the corresponding container from the intermediate storage and supply for further processing controls.
- the system thus comprises a handling system which, under the control of a system controller, automatically transports or removes containers to or from the temporary storage facility.
- the containers filled with tablet pellets remain in the interim storage facility during the respective product-specific curing time, which is stored in the plant control.
- the tablet pellets can harden during a certain curing time in the interim storage. Only in the hardened Condition when the tablets have a high mechanical strength and no size changes due to shrinkage or expansion, they are removed from the handling system from the intermediate storage and fed to the coater.
- the handling system allows fully automatic handling of the container. A manual intervention is not necessary.
- the corresponding system thus ensures that for the tablet pellets in a container, the curing time is maintained before the tablet pellets are provided in the coater with a coating.
- the system comprises a detection unit which determines the quantity of tablet pellets in a container by number or weight.
- a detection unit which determines the quantity of tablet pellets in a container by number or weight.
- the tablet press is followed by a switch, which directs the output from the tablet press tablet pellets either to one of two or more filling stations, the filling stations are equipped with a container.
- a container can be connected at each filling place.
- a container arranged on a filling station can be filled, while a second empty container is arranged at a further filling station.
- the switch is preferably provided by the system control unit. It is redirected so that it redirects the tablet pellets to another filling station where a second empty container is connected.
- the handling system now removes, controlled by the plant control, the first filled container from the filling station and transfers it to a storage location in the storage facility.
- the tablet pellets can now be cured in the interim storage facility for the curing time stored in the system control.
- the number of storage bins to be provided in the interim storage facility is determined by the necessary curing time and the processing speed of the coater or tablet press.
- a container In order to enable continuous operation of the coater or the tablet press, a container must be removed from the intermediate storage facility on a regular basis, connected to the coater and emptied into the coater. The curing time of tablet pellets in the interim storage thus determines the necessary number of storage bins.
- the handling system takes the filled container of cured tablet pellets from its storage location in the interim storage and docks the container to an inlet opening of the coater.
- the handling system is configured such that it can actuate a closure device connected to the container and / or the coater, for example a pivotable flap, in order to open the relevant closure and thus initiate the filling process automatically.
- a closure device connected to the container and / or the coater, for example a pivotable flap
- the handling system closes the mentioned closure device and docks the container from the coater.
- the empty container ner is now ready to be filled with pressed tablets.
- the handling system can spend this empty container to an empty filling station in the area of the tablet press. Alternatively, the container can be parked on a parking space in the interim storage, until it is spent for refilling on a filling place.
- the container has an automatically optionally dust-tight opening or closing inlet opening.
- This is preferably designed operable by the handling system.
- the container can be opened or closed automatically.
- the dust-tight openings By using the dust-tight openings to be opened or closed, contact of the tablet pellets with the environment is prevented. There is no contact with an operator, so that the system can be operated in an automatic, closed operation.
- the plant preferably has a dedusting device for dedusting the tablet pellets.
- the tablet pellets can be dedusted and ensure that only completely shaped tablet pellets get into the further processing of the plant. This increases the reliability of the system.
- the deduster between the tablet press and switch is arranged. Thus, only one deduster is required for a tablet press, as dedusting of tablet pellets takes place before the flow of tablet pellets is directed through the diverter to different filling stations.
- the container In favor of a simple and thus economic design of the container can be provided that it has only a single opening. This serves on the one hand as an inlet opening when the container is placed on the filling station and filled with tablet pellets, and on the other hand as an outlet opening when the container is connected to the coater and the hardened tablet pellets are emptied from the container into the coater.
- the container particularly preferably has, in addition to the inlet opening, an outlet opening which can be automatically closed or opened in an optionally dust-tight manner.
- an outlet opening which can be automatically closed or opened in an optionally dust-tight manner.
- the outlet port is configured to connect to the coater inlet port.
