The three units of the blister line are the blister unit, connection unit, and cartoning unit. Due to the current production mode of the blister packaging line, there are more varieties and fewer batches. To improve production efficiency, the requirements for engineers on the blister line are to quickly change the format, thereby enabling rapid switching between production products.
Blister unit.
When pharmaceutical companies use blister packaging for drugs, they design blister cards of various sizes and blister shapes for different medications. When producing multiple blister cards on the blister machine, the corresponding blister format must be used. When changing the format, the traditional blister machine generally uses a screw and a nut or a slide and manually rotates the thread to move the corresponding workstations and parts that need to be adjusted; when the variety increases and the batch decreases, the adjustment becomes very frequent, which significantly increases the workload and reduces production efficiency. By using the Servo positioning system, the position adjustment actions related to format changeover are no longer done manually but by servo system, and the position data is stored in the system; when the blister machine has many sets of formats, the position data of each format is stored in the control system of the machine in the form of a recipe. When a specific format needs to be used, it is only necessary to select the corresponding position data in the system, and the position of the corresponding parts can be automatically set in place.
Cartoning unit.
Cartoning machines are similar to blister machines. When the size of the carton changes, the positions of many parts need to be adjusted. Traditional cartoning machines are generally adjusted by manually moving the screw, nut, and the position of the slide. When many carton sizes are produced on the same cartoning machine, it means that the production varieties need to be switched frequently, and format changes are often required.
To improve production efficiency and quickly switch between production varieties, the latest generation of cartoning machines has also begun to utilize the Servo positioning system. The Servo positioning system uses servo motors to adjust the adjustment position of mechanical parts. After adjustment, this set of data can be stored in the system. When there are many carton sizes, the system stores various data in the form of recipes. When a carton size specification needs to be produced, you only need to select the corresponding formula from the list, and the system will automatically adjust the position of the parts without manual adjustment. The high degree of automation and intelligence has dramatically improved the production efficiency of the cartoning machine.
The connection unit.
The connection unit transmits blister cards to the cartoning unit.
The connection unit is a crucial component in ensuring the stable operation of the blister line. When the product variety changes, the size of the blister card will also change, as will the number of blister cards in a carton, which can range from one to more. Consequently, the connection unit must be adjusted accordingly. Most traditional connection units are in the form of conveyor belts, and when adjusted, the specifications of the conveyor belts often need to be changed. The latest Servo positioning system’s connection unit has dramatically improved the automation of the system. The size of the blister card and the carton loading (one blister card per carton or multiple) can be automatically adjusted by the Servo positioning system. When multiple production varieties need to be switched frequently, the parameters of each array can also be saved in the form of a formula. When a particular parameter is required, just select it in the formula list, and the system will automatically adjust the position parameters of the connection unit.
In summary, the Servo positioning system has greatly enhanced the flexibility and production efficiency of the blister line. This improvement is particularly significant in today’s environment of multi-variety and small-batch production, making it a game changer.
