5 Key Variations Between Palletizing and Depalletizing


We frequently put the duties of palletizing and depalletizing collectively after we speak about automation. However, there are some key variations between these two logistical duties.

Do you have to deal with palletizing and palletizing duties in a different way?

Is one activity more durable to realize with a robotic than the opposite?

Might the identical robotic carry out each duties?

Once you perceive the particular necessities of palletizing and depalletizing, you can also make higher choices about including automation to your manufacturing workflow. It can provide help to to organize your facility for robotic palletizing and get probably the most out of your new funding.

Let us take a look at the similarities and variations between these two robotic duties…

The that means of palletizing

Palletizing means putting or stacking gadgets onto a picket, plastic, or steel pallet for transport or storage. It’s a important activity for logistics because it helps to keep away from harm or lack of merchandise throughout transportation. Billions of pallets are used worldwide every single day.

The normal method to carry out palletizing is to do it manually. A employee takes containers or different types of packaged merchandise from the manufacturing line and stacks them onto the empty pallet.

Extra lately, collaborative robots have turn into a preferred method to obtain palletizing. Robots are extra constant than human employees and assist to scale back the variety of accidents which can be frequent for palletizing employees.

The that means of depalletizing

Depalletizing means systematically eradicating containers, baggage, or different packaged gadgets from a loaded pallet. It’s usually the primary stage in a producing course of, the place uncooked supplies have arrived right into a facility loaded onto a pallet.

In comparison with palletizing, depalletizing is commonly a extra advanced activity. Nevertheless, robotic techniques can nonetheless carry out depalletizing with the proper setup.

A associated activity is “repalletizing.” Right here, gadgets are faraway from one loaded pallet and positioned onto a second pallet for additional cargo.

The similarities between palletizing and depalletizing

Earlier than we take a look at the variations between these two duties, it is price reminding ourselves of the similarities. Palletizing and depalletizing are clearly very related duties.

Some clear similarities between the 2 duties are:

  • They’re usually achievable with the identical robotic. The Robotiq Palletizing Resolution, for instance, works equally nicely for both activity.
  • They each contain transferring containers, baggage, or different gadgets between a set level (e.g. the top of a conveyor) and a recurrently organized sample on a pallet.
  • They’re each repetitive, boring jobs that individuals do not wish to carry out manually.
  • They’re usually a bottleneck to manufacturing in amenities, particularly when palletizing operators carry out a number of roles.

These similarities are essential if you end up deploying a robotic. They imply that you would be able to usually deal with palletizing and depalletizing collectively. The deployment and integration work that you just do for, say, palletizing will apply on to the deployment of a depalletizing activity, and vice versa.

5 Key variations between palletizing and depalletizing

There are additionally some essential variations between palletizing and depalletizing. Despite the fact that the duties look related, you’ll possible encounter distinctive challenges with one which may not come up — or would come up in a unique kind — with the opposite.

Some key variations between the 2 duties are:

1. Unloading challenges

With a palletizing activity, you management all the things concerning the gadgets on the pallet. The robotic picks up the field from a conveyor, for instance, and locations it in a exact location on the pallet.

With depalletizing, you’re unloading gadgets from a pallet that anyone else loaded. There’s at all times a chance that gadgets shall be in surprising positions on the pallet or the distribution of things is inconsistent.

2. Objects moved in transit

Pallets transfer lots throughout transit. Securing the load with insufficient shrinkwrap is without doubt one of the commonest errors in palletizing.

If you end up depalletizing, it isn’t unusual for gadgets to have moved in transit. Your depalletizing robotic should have the ability to account for such motion or it can make errors.

3. Robotic imaginative and prescient

A standard method to deal with the uncertainty of unloading pallets is to add robotic imaginative and prescient to depalletizing functions.

Imaginative and prescient sensing provides to the complexity of your robotic utility, nevertheless it improves the system’s flexibility to modifications. With palletizing, you may usually get away with out including any imaginative and prescient sensing to your robotic.

4. Totally different upstream and downstream processes

A transparent distinction between palletizing and depalletizing is that they work together with totally different processes in your manufacturing workflow.

Palletizing duties normally come after upstream packaging duties, similar to sealing, labeling, and case erecting.

Depalletizing duties normally come firstly of your workflow and can work together with duties like selecting, sorting, and unpacking.

5. Location in your facility

Possible, a palletizing and depalletizing robotic will sit in numerous places in your facility. It would be best to find the robotic near whichever upstream or downstream processes come earlier than or after it in your workflow.

In case your manufacturing portions are low, you may have the ability to use the identical robotic for each palletizing and depalletizing. In that case, you have to to take this into consideration whenever you design your robotic cell and determine the way it will match into the structure of your facility.

The best way to determine in the event you want a palletizing or depalletizing robotic

Do you want a palletizing or depalletizing robotic in your personal facility? Perhaps you want each?

There are some questions you may ask your self that will help you discover the most effective palletizing resolution in your distinctive state of affairs.

Ask your self questions like:

  • Do now we have most bottlenecks in the beginning or on the finish of our workflow?
  • The place within the facility can we need to place the robotic?
  • Can we need to attempt to carry out each duties with the identical robotic or have a number of robots?
  • What could be our throughput of product for both of the duties?
