Granular bag packing machines also known as bagging or bagging machines, this type of packaging equipment fills pre-made bags with product and then seals them. There are two main varieties of bagging and sealing machines: rotary and roll-on. This pellet bag packaging machine design saves valuable factory space and is designed with packaging simplicity in mind.
The granule bag packing machine first loads the prefabricated bags. There can be one, two or four "lanes" of prefabricated bag filling, with the single-lane (single lane) model being the most popular. When a single bag feed does not meet throughput needs, it is time to upgrade to a model with additional lanes. As the bags are fed into the packaging machine, they are clamped and held as the rotary table moves counterclockwise through different static machine "stations" arranged in a circular fashion around the perimeter of the device. Granular packing machines typically have 6-10 stations, the most popular configuration being 8 stations. Different steps of the bag filling and sealing process take place at each station.
Bagging: Automatic pouch filling and sealing machine robot feeding. PNG preformed bags are first loaded into the bag bank of the granular packing machine. This is a manual process done on a regular basis by careful human operators. The bags are then conveyed to the inside of the machine by feeding rollers.
Clamping Bags: When the proximity sensor detects a bag in the magazine, the bag is grabbed by the vacuum suction cups and lifted onto a set of bag clamps to prevent the bag from reaching every position of the bag along the way. A note on stand-up pouches with pour spouts: Some fluid bag packaging machine limitations mean that your spouted pouches must be within certain design parameters in order to be properly grasped by a pellet packaging machine.
Opening the bag: In this step, the vacuum cup grabs the outside of the fluid bag and gently opens the bag. If the bag is equipped with a zipper, the vacuum will open the bag and the top of the bag will be opened by the splayed jaws. In either case, a blast of clean air is used to ensure the bag is fully open and ready to fill. The bag area has sensors to detect the presence of the bag. If a bag is skewed or lost, these sensors transmit it to a filling and sealing station unrelated to that particular bag. This ensures that spills and product loss are virtually eliminated, and that empty bags can also be reused in future cycles.
Product Filling: Now, the predetermined dose of product is filled into the bag through the lower hopper filler, the settler will "shake" the bag to force the solid ingredients into the bottom of the bag in the granule packer.
