Vertical bagger machines are being used today as an important component of modern packaging systems where high speed, accuracy in packaging in different types of packaging material and form of products whether it is powdery or granular, and some liquids is highly desirable. The basic elements and working of vertical bagger machines for enhancing packaging practice has been described in this article.
What is a Vertical Bagger Machine?
Form fill seal machine also known as vertical bagger machine, is specifically intended to package products in vertical manner. Contrary to horizontal bagging systems, it generates the bag from a roll of film, packs the product into it and seals it vertically. This makes them suitable for use with large products which experience free flow which is common with the food, pharmaceutical, and hardware industries.
Key Components of a Vertical Bagger Machine
To understand how a vertical bagger machine works, it’s essential to know its main components:
Film Roll: This is where the packaging process of the product begins as well. A roll of film can be made of Poly Ethylene, Poly Propylene or can be a Laminate material which is to be loaded in the machine. It most depends on what product is to be placed in the film and what properties the film should provide such as strength, barrier ability, or ease at which the pack can be sealed.
Forming Tube and Collar: During the running process, there are forming tube and collar which give the film tube like appearance. The collar ends shape the material for the bag in the beginning and it is wrapped around the entire film. It also controls the position of the film so that sealing can be well aligned based on the collar.
Vertical Sealing System: After the formation of the layer by layer in the form of a film tube, a vertical sealing system describes the edges to make the continuous tube. With regards to the type of material used, this seal may be created with heat or pressure. Sometimes, a particular method is employed when making the seal to make it stronger especially for the heavy products or large products.
Product Filling System: After the formation of the bag has reached a halfway, the final product is dropped down through the forming tube into the partially formed bag. Depending on the type of products it deals with, filling mechanisms are available in the form of auger fillers for bulk products, volumetric cups for granular products, and multi-head weight fillers for of irregular shaped products. Some machines have vacuum or gas flushing systems to worry about the product freshness in their hold.
Horizontal Sealing and Cutting System: Once the product is filled, airtight-sealing arrangement seals the top of the filled bag and the bottom of the next bag simultaneously. This make sure that the machine is running all the times thereby increasing on the speed and productivity of the machine. A cutting system then straps the sealed bag away from the tube in the manner of an individual package in preparation for the next process step.
Control System: The current vertical bagger machines have sophisticated control systems that are usually managed by a touch screen. These controls enable operators to get to choose on different elements including the length of the bag, the fill quantity, and the seal temperature. Engines enable consistent and accurate returns throughout the batches hence standardization.
How Vertical Bagger Machines Work?
The vertical bagger machine operates through a synchronized sequence of steps, all aimed at ensuring high efficiency and precision:
Film Unwinding and Forming: This forms the basis of the developing process when the film roll pulls and encircles the forming tube. The following apparatus of the machine helps to control the tension of the film and make a correction also:
Vertical Sealing and Bag Formation: The forming tube compresses the film to assume a cylindrical shape and the vertical sealing system welds the edges of the layer together to give a tube. This continuous tube then becomes the packs for the individual bags and with each bag being filled individually and sealed.
Product Filling: Another important control technique is the use of a sensor or timer to initiate the filling which in turn releases the correct volume of the product for packing in the formed bag. The possibility of controlling the rate of filling is another advantage depending on the kind of a product and the overall production capacity needed.
Horizontal Sealing and Cutting: Following filling, the horizontal sealing bar across the flow direction seals the end of the bag top and bottom and the cutting system cuts the filled bag. This action occurs almost concurrently with the formation of the next bag; this makes it possible to have the machine running at all times.
Advantages associated with Vertical Bagger Machines
Vertical bagger machines offer several benefits that make them a popular choice across industries:
Space Efficiency: Compared to horizontal baggers, vertical form fill seal machines adopt a vertical position and thus, remain compact to accommodate tight space production floors.
High Speed and Productivity: Vertical baggers are fast forming, filling, and sealing functions making it versatile for high demands and production. Most models are capable of processing up to 100 bags each minute.
Versatility: The machines can accommodate any type of product and bag, making it easy for businesses to package products of different nature. They can also change of the size of the bags and volume of fill making it convenient for various production requirements.
Cost-Effectiveness: In vertical bagging, roll stock film is used instead of bags and therefore bagging material costs are cut down. They also involve least amount of manpower with the use of the control systems hence it is inexpensive in the long run.
Conclusion
Expanding the knowledge of the vertical bagger machines will show that these are rather important elements of modern packaging. These machines offer possibilities of cost effective, fast and secure operations in several industries eliminating the packaging processes with high precision and quality. With time, innovation of vertical bagger machines is set to progressively experience integration of newer and more efficient features, making the machines more efficient in support of businesses planning to upgrade their packaging processes.
