Advanced Technical Features

Modern deblistering machines come equipped with PLC (Programmable Logic Controllers), touchscreens, and advanced automation features to improve efficiency and monitoring capabilities.

4. Manual vs. Semi-Automatic Deblistering Machines

There are two main categories of deblistering machines: manual and semi-automatic.

Semi-Automatic Machines

Semi-automatic deblistering machines involve partial human intervention. These machines often include:

• Rotating Blades that cut through the blister pack material, efficiently extracting the products.
• Electric Motors and Rollers that help move blister packs through the machine.
• Electronic Counting Systems to keep track of the number of items processed.
• Waste and Product Separation Chutes to ensure that recovered products are collected separately from waste materials.

Semi-automatic machines strike a balance between human effort and automation, making them ideal for medium-scale production where speed and efficiency are important but human involvement is still required.

Manual Machines

Manual deblistering machines are the most labor-intensive. Operators must manually feed the blister packs into the machine and extract the products by operating levers or handles. These machines are typically used for small-scale production or situations where only occasional deblistering is needed. Though cheaper to purchase and install, they can be slow and physically demanding, which makes them unsuitable for large-scale operations.

5. Components of a Deblistering Machine

A deblistering machine consists of several components that work together to ensure a smooth and effective operation. These include:

• Set of Rollers: Rollers help transport the blister packs from one station to another, guided by electric drives and motors.
• Set of Chutes: One chute is designated for waste materials, while another is used to collect the recovered products.
• Metal Rollers and Rubber Wheels: These components work together to gently remove products from their blister packs, minimizing the risk of damage.
• Collection Box: This is where the recovered products are deposited for further processing.
• Touchscreen HMI Panel: This interface allows operators to adjust settings such as speed, spacing, and operation mode. It also enables monitoring of the machine’s performance.
