Multi Head Packing Machine

What is Multi Head Packing Machine?

Frankly speaking, the multi head packing machine should be called the multi head packing line, because it is composed of a variety of different equipment.

Weighing and packaging are the most important processes of a multihead weigher packing machine, the multihead weigher is responsible for weighing, and the VFFS machine is responsible for packaging.

The weigher packing machine can not only accurately weigh the products, but also automatically package the weighed products, it is very efficient and easy to use.

Working Principle of Multihead Weigher Packing Machine

According to the below picture:

multihead-weigher-packing-machine-workflow

The basic workflow of the multihead weigher packing machine is:

  • Material Feeding
  • Weighing
  • Bag Making
  • Filling
  • Sealing
  • Date Coding
  • Discharging
  • Checkweighing
  • Cartoning

Next, let me introduce the multihead weigher packing machine’s working principle in details.

  • Material Feeding

Generally speaking, the upstream production line’s outfeed conveyor transports materials to the hopper automatically, or workers manually add materials to the hopper.

The materials in the hopper directly fall onto the feeder, the feeder vibrates the material into the infeed conveyor’s buckets.

vibrating-feeder-2

The infeed conveyor lifts the material upward, and then dumps the material into the multihead weigher’s infeed chute.

  • Weighing

The multihead weigher is responsible for the task of weighing.

The materials enter the multi weigher’s dispersion feeder from the infeed funnel.

Multihead-Weigher-2

The dispersion feeder distributes the material to each radial feeder through vibration, and the radial feeder disperses the material to each pool hopper through vibration.

Multihead-Weigher-4

After the last weighing is completed, the material in the pool hopper enters the weight hopper for the next weighing cycle, the load cell in the weight hopper feeds back the weight to the PLC.

After the PLC runs the combination calculation, it determines the weight hopper combination that is closest to the target weight, and sends a command to the corresponding weight hopper, release the materials to the discharge chute.Multihead-Weigher-5

When the timing hopper receives the release command, it will open the discharge chute and outfeed the materials to the VFFS machine’s inlet.

Multihead-Weigher-6

  • Vertical Form Fill Seal (VFFS)

While the timing hopper is waiting for command to release the material, the vertical packaging machine starts to work according to the steps of form, fill, and seal.

As shown in the figure below, the vertical packaging machine is mainly composed of a film pulling system, a former, a horizontal sealing device, a vertical sealing device, a cutting device, and a photoelectric monitoring system.

vffs-machine-schematic

The film is transmitted to the forming tube through the film pulling system, passes through the collar, and is stretched down by two sets of high-quality pulling belts.

film-reel

Film Reel

film-pulling-system

Film Pulling System

When the machine first starts, it will manually make one pouch first. After the manual bag making is completed, the bottom bag is cut off, and the upper bag’s bottom is also sealed into shape.

During the down-stretching process, the sealed bottom goes down, and the vertical sealing bar first melt the vertical edges on the film’s both sides, bond the film until the bond length reaches the preset value.

vertical-sealing-bar

Vertical Sealing Bar

At this time, a pouch with only the top opening is formed, the timing hopper receives a command to release the material to the open pouch.

After the filling reaches the preset gross weight, the filling stops, and the horizontal sealing jaws seal the top of the bag and forms the upper bag’s bottom at the same time.

horizontal-sealing-jaws

Horizontal Sealing Jaws

In this way, the form, film and seal of the pouch are completed cyclically.

If it is a pre made pouch packing machine, the product packaging process mainly includes the following steps:

  • Pick-up Doypack

The doypack is picked to the gripper, no pouch warning, reducing the labor intensity;

  • Print Date Code

Ribbon detection, alarm when the ribbon is used up, touch screen display to ensure the normal date coding;

  • Open Pouch

Open the pouch to detect, if bag is not open, no filling, avoids wasting material;

rotary-pouch-packing-machine-1

Rotary Pouch Packing Machine

  • Fill Material

Inspection, if no material, no filling and no heat-sealing, to ensure that the bag is not wasted;

  • Heat Sealing

Alarm for abnormal temperature to ensure sealing quality;

  • Cooling, Shaping and Discharging

Ensure that the seal is beautiful.

  • Discharging

After the pouch is cut off from the forming tube, it is a packed pouch, which drops directly onto the outfeed conveyor belt and forward to the downstream equipment.

outfeed-conveyor-3

  • Metal Detection & Checkweighing

Generally speaking, the packed food pouches will first be conveyed to the metal detector, and the metal detector will detect whether the food pouches contain metal.

If metal is detected in a certain food pouch, the pneumatic push rod will remove it to the waste collection box.

metal-detector-1

Metal Detector

The food pouches passed by the metal detector will forward to the checkweigher, check whether the packaging weight is within a reasonable range of the target weight.

checkweigher-1

Checkweigher

Food pouches that do not meet the target weight will also be rejected into the waste collection box.

  • Cartoning

After food pouches pass metal detection and checkweighing, they go ahead to the case packer or cartoner machine for cartoning.
