In pharmaceutical packaging, changing from tablets to capsules is more than a simple product switch. Different shapes, dimensions, surface characteristics, and flow behaviors can affect feeding and counting performance. For operations using an automatic pill counter, the changeover process needs to be controlled carefully to maintain counting accuracy, reduce downtime, and support consistent filling.
At Pharmapack, we design tablet and capsule counting equipment with practical changeover requirements in mind. Our LF series uses vibratory feeding, multiple counting channels, sensors, and a control system to move products into bottles according to preset quantities.
Why Tablets and Capsules Require Different Checks
Tablets and capsules may differ significantly even when they have similar dimensions. Tablets can be round, oval, or caplet shaped, while capsules have a longer cylindrical profile and may behave differently as they travel through feeding channels.
An automatic pill counter must therefore provide stable product separation before the products reach the detection area. Pharmapack counters use multi-grade vibratory plates to guide products into single-file channels before they pass through detection tunnels. This allows the counting system to identify individual products as they move through the machine.
Before changing products, operators should confirm the applicable product size range, feeding behavior, preset count, and bottle specifications. These checks help determine whether adjustments are required before production resumes.
Check Product Dimensions Before Changeover
Product dimensions are one of the first factors to verify when switching between tablets and capsules. A machine configured for one product should not automatically be assumed to perform identically with another.
For example, Pharmapack's LF-12 supports products with a thickness of 3 to 10 mm, diameter of 3 to 13 mm, and length of 3 to 21 mm. Its filling quantity can be set from 1 to 1,000 pieces.
Operators should compare the dimensions of the new product with the machine's specifications before starting the next batch. If the product falls outside the applicable range, a different counter configuration or additional engineering assessment may be required.
Inspect Feeding and Counting Settings
Once the product dimensions have been confirmed, the feeding system should be checked. Vibratory frequency has a direct role in how products move through the channels. Excessive or insufficient vibration can affect product separation and create unstable feeding conditions.
For the LF-12, products are fed through 24 channels and then enter 24 detection tunnels. Sensors work together with the control system to count the products before the preset quantity is released into each bottle.
During a tablet to capsule changeover, operators should therefore verify the vibration settings and observe whether products are moving individually and consistently. The counting result should also be checked against the preset quantity before normal production begins.
Review the Bottle and Filling Interface
Changing the product may also require attention to the filling side of the machine. Bottle diameter, height, neck configuration, and product quantity can affect the filling process.
Pharmapack's LF-12 accommodates containers with diameters from 20 to 100 mm and heights from 40 to 240 mm. The system uses a nozzle gate and filling nozzle to transfer the counted products into the bottle once the preset count is reached.
In practical operation, the nozzle should be checked after a product changeover, particularly when tablets and capsules have different shapes or lengths. A suitable filling interface helps reduce product accumulation and supports stable transfer into containers.
Cleaning and Product Contact Parts Matter
Cleaning is another important part of tablet and capsule changeover. Residual products from the previous batch can create cross-product contamination risks and interfere with the next production run.
The LF-12 uses Type 316 stainless steel for product contact parts, and these parts can be disassembled for cleaning. The machine is also designed to require relatively few change parts for different container sizes, with the nozzle being the primary adjustment point specified by Pharmapack.
After cleaning, operators should inspect product contact areas, feeding channels, detection tunnels, and filling components before introducing the next product. The goal is to confirm that no previous product or debris remains in the product path.
Verify Counting Accuracy Before Full Production
A changeover should not be considered complete immediately after the machine starts running. A short verification run provides an opportunity to confirm that the new product is being fed and counted correctly.
The operator can check several consecutive filled containers against the programmed quantity and observe product movement through the counting channels. If the count is unstable, the feeding conditions, sensor settings, and product flow should be reviewed before continuing production.
For facilities looking for a pill counter for pharmacy or a larger pharmaceutical packaging line, these verification steps are particularly useful when multiple product formats are processed on the same equipment.
A Practical Approach to Tablet and Capsule Changeovers
For Pharmapack, an effective changeover combines suitable machine configuration, controlled product feeding, accessible cleaning, and counting verification. Our LF-12, for example, provides a maximum output of 12,000 pieces per minute depending on product characteristics and is designed for tablet and capsule counting applications.
When selecting an automatic pill counter, buyers should look beyond maximum speed. Product compatibility, changeover requirements, cleaning access, container range, counting technology, and integration with the existing packaging line all deserve consideration.
A well-planned changeover helps maintain stable production when moving between tablets and capsules while reducing unnecessary adjustment time. Pharmapack provides tablet and capsule counting solutions designed around these practical production requirements, from individual counting machines to integrated packaging systems.
