Modern medical technology advances, new dosage form and route of administration allows the continuous development of medicine. In the solid preparation, the tablets because of its ease of taking, is still the most widely used dosage forms.
The high-speed packaging technology can effectively improve efficiency and meet the requirements of large-scale production and GMP. General tablet is one of the main forms of packaging bottling,glue stick bottled linkage device in the number of tablets machine is the key to the whole line. Currently, the number of tablets usually a few grains of multi-channel electronic means. Tablets and other drugs through the hopper vibrator vibration level by the transfer of materials to the feed channel, following the vibration after the feeding, so that even turn into pharmaceutical combination of optical and shattering the cylinder port, then a few grains of photoelectric sensor signal acquisition time feedback to the PLC control device, the PLC controls the internal operation cylinder, respectively, compared to the implementation of a few grains of functions. Among them,glue gun the feed directly to determine the good and bad channel quality pharmaceutical packaging.
Recently, the Italian Marchesini company designed a new, ergonomic tablet channel feeders MT1000, can effectively solve the feeding problems during the tablet overlay, and a significant reduction in feed length.
1 characteristics.
The equipment was installed in the channel net for catching rabbits feeding machine, enter the feed channel in the tablet using a new type of active location and arrangement of technology to control, which uses an intelligent screw feed technology to solve the channel overlap tablet provides a simple way, and a significant reduction in the length of feeding.
The new MT1000 channel feeders do not undermine the quality of the sharp edge tablet, blind cleaning, and easy to gather dust or debris and other shortcomings. Therefore, the design to meet the clean, pollution-free environment GMP requirements.
2 Structure and principle.
2.1 structure.
Channel feeders Chenglu desktop structure, all sports have been set in the electrical panel on the back of the machine to work with regional isolated products, and its electrical cabinet with mobile convenience features. The lower part of channel-type feed system is designed to open style, so that dust generated automatically fall into the bottom, and there is a centralized dust collection system. All major mechanical drive machines are used to drive the brushless motor.
2.2 Principle.
The channel-type feed system, feed and positioning with the existing number of tablets Feeding electronic parts compared to more compact.
The principle: the feed channel feed using a loose manner, tablets into the tube through its orientation by the automated processing system to control, the system uses a conveyor belt into the seat with a piece correctly predicted directional feed. Once the system is not properly placed piece seat tablet, this time with a patented built-in recovery system will be automatically directed to the tablet. The set arrived in the channel between the conveyor belts and directional devices can spiral feeding body tablet to reach the correct channel position to the feed, there will not be owned or overlapping different tablet shown in Figure 2. Then, the tablets directly in the channel selection classification, and safely transported to the packaging container.
In the channel with two parallel conveyor belts, each conveyor belt is equipped with a separate engine, equipped with 4 sets of the top 12 channels corresponding to the container. 4 sets of containers that are set in a unit, mainly for the following: feeding, feeding, orientation, placement. Because the two conveyor belts have their own engine, making them independent of each other, respectively, for feeding, the tablet to move to their respective holders pairing channel. The system with synchronous dynamic movement to eliminate their mutual jamming, making the process more smooth and continuous.
Subsequently, the channel of the conveyor belt will be sent to the bottling tablet down the channel so that it can be vertical feed. 12 tip with a mechanical hand to a group of 12 tablets while inhaling, and 90 ° rotating the bottle directly into the packaging shown in Figure 3.
3 advantage.
The channel-type feeder is completely innovative inventions, which is a reliable feeding system, has the following advantages: (1) tablet sustainable manner feeding, non-stop delivery of legacy and monolithic; (2) tablets not pressure or friction, so as to maintain the integrity of the tablet; (3) direct control through the computer system to ensure that the selection of films and counting operations; (4) parameter can be set through the computer, the process The impact of changes can be automatically calculated, reducing friction and impact.
Now, all of these features make the tablet channel feeders MT1000 level of technology is more advanced, able to effectively meet the number of films for pharmaceutical packaging market in the specific packaging requirements.
4 more to meet the GMP.
Because of its lower channel-type feed system is designed as an open style, so that the resulting dust can fall into the bottom, and there is a centralized dust collection system. Therefore, the device greatly reduced pollution of the environment, avoiding the tablet before the dust generated during packaging, thus reducing cross-contamination. In addition, the aircraft are all major mechanical work to drive the brushless motor, so the motor will greatly reduce the pollution.
Loose open feeder, in reducing environmental pollution, but also greatly reduces the difficulty of cleaning and disinfection of equipment. In addition, the operating system control on the selection of films through the computer and count parameters, while monitoring the feed by the impact when the tablet, thereby reducing friction to ensure that the tablet film parameters and process re-order differences in conformity to the standard .
