Literature Review
 Pouch packing machines are commonly known as Form Fill and Seal Machines. There are classified as two main types– Vertical Form Fill and Seal Machines and Horizontal Form Fill and Seal Machines. Vertical Form Fill and Seal Machines (VFFS Machine) are used to pack regular shaped solid products or liquids while, Horizontal Form Fill and Seal Machines are used to pack irregular shaped products. In this paper we focus on the Vertical Form Fill and Seal Machines. VFFS machines are widely used in most of the industries to pack products of various sizes (depending on their weights).
Tumblr media
The VFFS Machines are again classified in two waysAccording to their type of motion (Continuous motion and Intermittent motion) and According to their type of automation (Fully automated and Semi automated). In making of the pouch two seals have to be made horizontal and vertical as it will be further explained in detail. Intermittent motion machine makes the vertical seal while the film is in motion but for the horizontal seal the film stops whereas, the continuous motion machine makes the vertical and the horizontal seal without stopping the film. Hence, higher production rates can be achieved by the continuous motion machine. On the other hand, Fully automated machine requires no human intervention while Semi automated machines require humans to perform some part of packing operation. The machine discussed in the paper can be classified as an intermittent motion machine or fully Automatic machine.

Need of Automation
Pouch packing involves a number of steps like bag forming, weighing, and sealing the bag. If all these processes are to be done manually, the time required is more. The production rates will be slow. In order to achieve higher production rates use of automated machines is necessary. Automated machines are time savvy which gives the entrepreneurs to gain a competitive edge. The quality of the work is high and is repetitive. Automated machines can help reduce the waste generated hence, leading to proper utilization of the resources. Workers may suffer from fatigue which might lead to improper job quality. Use of an automated machine lessens the labour dependency of the enterprise. The key to achieve all of the above stated advantages while keeping the cost to be minimum is Low Cost Automation.
Tumblr media
A pouch packing machine can be automated in different ways. The three main types of automation techniques are Relay Logic control, Programmable Logic Control (PLC) and Microcontroller technique. Relay Logic Control uses relays interconnected to each other by wires to operate. A relay logic control panels are very large, sometimes large enough to occupy a wall. The life of a relay is limited so some of them need to be replaced, in order to replace a relay the machine needs to be stopped and eventually the production. To discover an error is very tedious as it is a very complex system. Electricians need to be very skillful in finding errors. The control system is very inflexible so changes cannot be done easily. Due to all such reasons, relay logic control is obsolete.
A Programmable Logic Controller, PLC or Programmable Controller is a digital computer used for automation of electromechanical processes, such a control of machinery on factory assembly lines, amusement rides, or light fixtures. PLCs are used in many industries and machines. Unlike general-purpose computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed-up or non-volatile memory.
Tumblr media
Microcontroller is commonly used term for a small computer on a single chip, which contains the microprocessor, memory and other accessories. Microcontroller has reduced size and price in comparing with other devices. Microcontrollers very frequently have amount of accessories like analog-todigital converter, digital-to-analog converter, programmable timer and counter etc. Powerful and carefully chosen electronics embedded in the microcontrollers can.PLC requires programming software, PLC control console and a computer to operate, whereas a microcontroller combined with some accessories can complete the job of automating a machine.The cost of PLC control is more than that of a microcontroller unit. PLCs are more flexible than microcontroller units but in this case, flexibility required is very less. Due to all such reasons, the microcontroller technique is much more suitable to achieve Low cost automated packing machine. Hence, in this case microcontroller technique is used.

Smart Food Packaging Bag
Function Change face Andrew Mills, a professor at the University of Strathclyde in the United Kingdom, is leading researchers to develop this smart packaging bag. If foods such as meat, fish, and vegetables exceed their shelf life or are stored outside the refrigerator for too long, their freshness will be impaired. According to the vision of the Mills team, when the freshness drops to a certain limit, this smart plastic packaging bag will change its color. This also reminds people to store sealed food in the refrigerator. If the packaging is damaged and the food quality is endangered, this plastic bag also has a warning. Researchers say that it can also help people distinguish between the “best eating period” and the “quality shelf life” without worrying about eating up their stomachs.
Tumblr media
Can ventilate The “freshness indicator” that people usually use is a label placed in a food packaging bag, and the cost is not low. Mills and others hope to develop a new indicator to integrate it with plastic bags, thereby reducing costs. Mills said: “The principle of the “air-conditioning packaging bags” currently promoted is mainly to inhibit organic matter from decomposing food, but the price is considerable. We plan to develop new plastic products to reduce prices.”
The new food packaging bag will have a “ventilation” function like an air conditioner, extending the shelf life of food. “Air conditioning” is not to adjust the temperature, but to reduce the amount of oxygen in the sealed bag, and fill it with nitrogen and carbon dioxide to reduce the natural spoilage rate of food.
Help save Official statistics show that each person in the UK throws away about 830 tons of food. Every year, 36.4 tons of edible food are thrown away because they exceed the “best eating period”. Among them, 3.9 tons of large amounts of food are opened. Mills said: “People today throw away junk food. No matter what or development, this is a kind of ocean.” Mills said that this smart packaging bag will be on the market within two years. Will help housewives reduce waste.

Principle of the System
The material is fed into the hopper whichis situated on top of the machine. The hopper has a pipe attached to it at the bottom through which the material passes. The pipe  has  a  flap  arrangement  to  allow  or  prohibit  thefurther  flow of  the material.  The flap is actuated by a pneumatic cylinder, when the flap is open the material falls into a bowl. A load cell is placed beneath the bowl to measure the weight of the material falling in it.
When a specific amount of material falls into the bowl, flap is closed and the bowl rotates thus emptying it into the  forming  tube.  The  forming  collar  shapes  the  flat film into a   round  film tube.  Low  friction rollers guide the film to the forming area and maintain tension in the film  thus   preventing  it   from  slagging.   Vertical  heat sealers  seal  the  edges  of   the  round  film  tube.  Draw rollers  pull  the  bag  downwards  after  the  vertical  seal has been done which also unwinds the plastic film from the roll. Cross sealing jaws create top and bottom seals in the pouches. A cutter separates the pouches which is placed   between  the   cross   sealing   jaws.  Finally,   an accurately weighed pouch is made.
Tumblr media
In   the   design   shown    above,   a   separate   weighing mechanism is added. Load cell arrangement allows for accurate measurement of the material to be filled in the pouch.   Load   cell   arrangement   allows   for   accurate measurement of the material to be filled in the pouch. When  the  bowl  is  filled  with  the  specific  amount   of material, it rotates and the material falls in the forming tube.   A  pneumatic   cylinder   and   disc   arrangement rotates  the   bowl.   The  forming   collar  is   a   uniquely designed  structure   by  which   the  flat  plastic   film  is turned into a vertical round film.  
Heat sealers are mounted vertically and horizontally to make   vertical  and   horizontal  seals.   Two   horizontal sealers are placed to make the bottom and top seals of the    pouch.    These   heat    sealers    are    actuated    by pneumatic cylinders. A set of draw rollers are mounted vertically  on  the  forming  tube  which  pull  the  formed plastic downwards. These rollers are rotated with the help   of   a   motor.   A   cutter   is   placed   between   the horizontal seals to separate two consecutive bags from each other.

Scale Feed Shakers
Scale feed shakers are specialized vibratory conveyors that feature either mechanical drives or electromagnetic drives. While horizontal motion can be used to feed scales, vibratory shakers offer the advantage of spreading and smoothing the product uniformly across the pan, which improves feed. The goal of this shaker is to evenly feed the scale so it is never overfed or underfed.
The most basic relationship between the scale and the scale feed shaker uses the scale’s infeed funnel as an accumulation device and a load cell or a level eye at the top cone of the scale that sends a digital on/off signal to the upstream scale feed shaker to stop and start, as needed. This method of integration, referred to as “plop and drop” or “flood feeding,” is less than optimal. This highly ineffective strategy has a tendency to overfeed the scale at the start and then starve the scale before turning back on, which hurts accuracy and speed and thus, has a significantly negative impact on the output of the FFS machine. Unfortunately, this method of scale feeding is widely used. Fortunately, there are several options available
for processors to optimize scale feeding and scale operations, which increase FFS machine efficiency and ultimately profitability, by providing a steady stream of product from the scale feed shaker at the proper flow rate.
Tumblr media
One way to achieve this is to utilize a load cell or optical sensor at the top cone of the scale to send an analog signal to the scale feed shaker based on the weight or the height of product on the weigher’s top cone. The analog signal will speed up or slow down the flow rate of product from the scale feed shaker. This is designed to maintain a constant weight or height of product on the scale.
Slight changes in speed may be required to adjust for bulk density changes in the product. Maintaining a constant weight or height of available product on the weigher’s top cone assures good product distribution to each bucket, which optimizes weights and speed.
An additional improvement, called volumetric flow control, integrates the analog scale signal with a photo eye on the scale feed shaker, which monitors the volume of product and controls the distribution shaker upstream to feed a specific amount of product to the scale feed shaker. Since bags are filled by weight, not volume, volumetric flow can be improved upon, especially when the density of the product varies.
The most accurate way to achieve a steady stream is called mass flow control. It integrates the analog scale signal with a load cell on the scale feed shaker, which monitors the weight of product and regulates the distribution shaker upstream to feed the perfect amount of product to the scale feed shaker.
Product flow from the upstream distribution shaker to the scale feed shaker are regulated by either a standard gate or a proportional gate. Standard gates simply open and close.
Proportional gates allow the aperture to vary and thus, better control the amount of product flowing to the next stage. Using a proportional gate upstream of the scale feed shaker is an ideal way to control product flow. Snack food processors with a seasoning application drum between the shaker and the scale often settle on mass flow and proportional gates since these systems maintain the most constant feed rates, which will achieve the most uniform seasoning.

Distribution Shakers
Distribution shakers transport product from the processing line to the scale feed shakers. Typically, each processing line leads to one distribution system that features multiple shakers and gates that discharge product to multiple scale feed shakers, each of which feed a scale and FFS machine. Depending on the type of distribution shaker used, the configuration of the system, and the controls, line efficiency and product quality are both affected at this stage.
The distribution shaker can be a traditional vibratory shaker or a horizontal motion shaker. Horizontal motion shakers are ideal for many fragile, seasoned, coated, and frozen foods because they offer gentle, quiet, and sanitary conveying. Both conveyor types can be fitted with standard slide gates, flip gates, pivot gates, or proportional-control gates to discharge product to downstream equipment.
Tumblr media
If the downstream scale feed shakers have sensors – either a photo eye that monitors the depth of product or a load cell that measures the weight of product – each gate on the distribution shaker can be controlled to feed the ideal amount of product to each scale feed shaker. Distribution systems can rely on data from volumetric or mass flow controlled feed shakers or unique optical sensors to control gates.On the most basic lines with the fewest sensors and the least integration, if the FFS machine goes down, the FFS machine signal causes a cascading effect on the slave systems, shutting them down. However, this basic line is incapable of making more minor adjustments to compensate for constant changes in line flow. Systems operated in this manner can often be identified by overfeed conditions at the first scales in the line, which choke the scales and reduce the accuracy of fills and cause bags to break, followed by underfeed conditions atthe subsequent scales, which stave the scales and reduce the output of these FFS machines.
On more sophisticated lines with more integration, each FFS machine controls its scale, which controls its scale feed shaker, which controls the gate on the distribution system so each machine is optimized individually as well as in combination. Each FFS machine can operate at different rates, producing different size bags, and the distribution shaker opens and closes each gate to discharge the exact amount of product to each scale feed shaker to optimize each scale and maximize the output of saleable bags being produced by every FFS machine.

Adding a Buffer
To maximize line efficiency and product quality, the distribution system must accommodate a constant flow of product coming off the processing line even when a FFS machine is down. This can be accomplished by either recirculating product or accumulating product.
If it is important to package the freshest product, as is the case with many snack foods, frozen poultry and seafood products, and fresh-cut produce, recirculation is not advisable because product could recirculate multiple times and then substandard product will be packaged and shipped. For these products, accumulation is preferred.
Product can be accumulated in different ways at various points along the line. If the distribution shaker is a horizontal motion conveyor that allows the flow direction to be controlled, the conveyor itself can be used for storage as well as distribution. The speed at which the distribution conveyors operate can also buffer the flow of product. Alternatively, a storeveyor or binveyor can be added to the line to provide bulk storage.
In some applications, select areas along the processing line can accumulate product without negatively affecting product quality. For example, a freezer could accumulate product without hurting product quality – a fryer could not.
Tumblr media
Control Systems
Each machine has its own control system. Among other things, the FFS machine controls how fast it pulls film and the time, temperature, and pressure of the sealing jaws; the scale controls the weight per charge; the scale feed shaker controls the product feed rate; and the distribution shaker controls its gates and product flow rates. The key to maximizing the performance of the line is linking these independent machines so they communicate with the others to improve the efficiency of the system.
On a fully integrated packaging line with integrated controls, one change on one machine or one point of input on one user interface automatically triggers all the necessary adjustments on other machines on the line. If a FFS machine goes down, upstream equipment automatically adjusts to accommodate it and continues to maximize the efficiency of the line, given the situation. If one FFS machine is changing over from a 14-gram bag to a 14-ounce bag, one point of input at one human machine interface (HMI) changes all the components on the line.
Typically, this high level of integration is achieved through a PLC at the distribution system level. If desired, data can be fed into a SCADA network so the system can be accessed from any computer on the network. Additionally, the network can be programmed to alert personnel via smart phones, tablet computers, emails, and/or text messages, regarding machine and system performance and conditions.
Conclusion
The benefits of optimizing a packaging line are numerous. Maximizing each FFS machine’s output of saleable product and eliminating product giveaway by producing on-weight packages goes straight to the bottom line. Maintaining high product quality promotes customer loyalty, and easing operations reduces training requirements
and helps the line operate at peak performance. Selecting right-size equipment that handles a specific product and produces the desired package is only the beginning of integrating a highly effective production line. To optimize the packaging operation, food processors – or their line integrators – must understand the interaction of the components and consider the line holistically rather than as separate machines that are connected. Fully integrating the controls costs more initially, but the added cost is quickly recovered by increases in overall equipment effectiveness (OEE) and the increased output of the FFS machine producing
saleable bags.

Packaging distribution systems
Packaging distribution systems that take solid food products from the processing line to form-fill-seal (FFS) packaging machines typically include conveyors with gates, scale feed shakers, and multihead weighers that feed either vertical- or horizontal-form-fill-seal machines. By understanding the interaction of these components and considering the system as a whole, processors can maximize the output of the FFS machine while maintaining the highest product quality and easing operations.
In this white paper, we will explore the physical relationship of the FFS machine to the upstream equipment. We will cover analog versus digital call signals, flood feeding versus steady state feeding, mass flow versus volumetric flow,proportional gates versus standard gates, integrated control systems, and more.The objective is to help food processors optimize their packaging operation by selecting machines that work harmoniously as a system and integrating the controls so the machines communicate seamlessly.Snack food processors arguably have the most challenging situation when integrated seasoning application systems are added to the line and small packages are produced at the fastest line speeds possible. However, the benefits of fully integrating the distribution system apply to all types of food processors. Whether the company is packaging snacks or baked goods, cereals, confections,shredded cheese, fresh-cut produce, frozen fruits and vegetables, nuts, poultry,seafood, or pet foods into flexible bags, the same considerations exist in lineoptimization.

Form-Fill-Seal Machines
A vertical-form-fill-seal (VFFS) or horizontal-form-fill-seal (HFFS) packaging machine is the anchor of the packaging distribution system. A processor’s preference in bag style and need for line speed mandate the decision to choose one type of FFS machine over the other, and upstream and downstream machines must complement it. Optimizing the output of the FFS machine is the goal of the packaging line because the quantity of saleable bags produced has a direct effect on the processor’s bottom line.
The FFS machine must pull film and achieve good seals with jaws that maintain the correct temperature, dwell time, and pressure while the ideal amount of product is filling each bag at a rate that optimizes the line. Thus, the success of the operation is dependent, in part, on the ability of upstream equipment to deliver the ideal amount of product to the FFS machine at the perfect speed with the necessary separation between product charges that allows the jaws to seal properly without product interfering and compromising the quality of the seal. To achieve this, the FFS machine and the scale upstream are integrated – the FFS machine is the system “master” because its demand for product controls the upstream equipment. For most solid food products, a multihead weigher, often called a radial combination is used in conjunction with a FFS machine because of its speed, accuracy, and reliability.
