Automatic Packaging Systems are increasingly being used by packaging and food manufacturing industries, they are simple, easy to use and provide a good quality of finished products. If you are planning to add pre-made pouch packaging to your product line up or else you are new to packaging automation. In this article, we have explained a simplified process of bag filling equipment and sealing machines. There are mainly two types of the bag filling and sealing machines, inline and rotary layout. We have discussed the rotary layout below.
- Bag Loading.
First of all, Operator puts manually preformed pouches or bags into the bag magazine in the front of the automatic bag filling and sealing machines. There is a bag feeding roller below the bags, which takes the bags to the machine in a serial manner.
- Bag Gripping.
The proximity sensor detects the bag and vacuum bag loader then picks up the bag, and place it to the pair of grippers, which ensures to hold the bag around the rotary unit. The best bag filling equipment and sealing machines grippers can support up to 10 kg of weight.
- Printing/ Embossing.
The packaging date or lot codes can be printed using thermal or inkjet printers, Bag is placed in front of inkjet printers, which prints the desired date and optional information at the Specified location on the product pouches.
- Zipper and Bag Opening Detection.
If there is a zipper to the bag, then the vacuum suction pad opens the lower part of the bag and top side with opening jaws. The bags are then inflated by the air blower, the vacuum suction pads can still open the bag if the zipper is not present. There are two sensors present at below the bag to detect its presence, however, if the bag is not placed correctly and is not detected below it, then filing and sealing spots will not use them, instead, it will stay in the rotator, until the next cycle.
- Bag Filing.
The products are filled into the bag with the help of funnel attached to the machine. The bag filling equipment ensures the quantity and measurement of the product to be packed in the pouches. They release a specified quantity of product into the pre-made pouches.
- Bag Sealing and Deflation.
Before sealing, the two deflators squeeze out the extra air from the bag and then a hot seal closer bar uses heat and pressure to close the upper part of the pouch and ensures the sealant layer to bond together strongly.
- Cooling and Discharge.
After sealing the pouches, they are passed over the cooling bars, to strengthen the seals and these finished bags are passed onto a conveyor and transported to check weight machines or any other options equipment and then finally discharged to pack them into a Cartons and Boxes for transport.
