Why Vacuum Grippers Are Actually the Greatest Choice for Robotic Palletizing


Vacuum grippers are a very fashionable finish effector for robotic palletizing. What makes them such a superb choice and the way do they examine to the options?

When you have been to go looking for images of palletizing robots, you’d see loads of pictures of vacuum grippers. They’re one of the standard finish effectors for palletizing robots, and with good motive! Vacuums grippers are very nicely suited to the wants of most palletizing duties.

Collaborative robots are simply as able to palletizing because the extra conventional industrial robots. With customizable vacuum grippers, cobots are the proper choice for light-weight packing duties.

Why are vacuum grippers so nicely suited to palletizing?

What different gripper choices are there?

How are you going to get began?

Let’s discover out!

5 necessities of a palletizing gripper

Packing is likely one of the most well-established duties for automation. Palletizing usually entails heavy payloads, personalized pallet layouts, and lengthy working hours — excellent for a robotic!

Palletizing additionally has slightly particular wants in the case of your robotic finish effector. Listed below are 5 of them:

1. Parallel Load

Most palletizing duties require that the objects are lifted from above — in different phrases, the lifting drive is parallel and reverse to the drive of gravity. In actual fact, there are an entire class of commercial “palletizing robots” which obtain this by all the time retaining their finish effector parallel with the ground.

2. Distributed payload

Many robotic duties solely require objects to be grasped by a single level. With palletizing, nevertheless, it’s extra widespread that objects are supported throughout their entire floor. This avoids twisting and deformation of the objects, and ensures that they’re packaged in precisely the fitting orientation.

three. Customizable

Each palletizing process is as totally different because the vary of objects which may be packaged. In consequence, it’s usually essential to customise the gripper in order that it completely fits the wants of the duty. Robots are sometimes required to vary between packages to permit for palletizing of various product traces.

four. Throughput

Palletizing is a excessive demand process and robots are sometimes labored constantly. This is sensible as a result of each product which leaves the enterprise must be packaged. Something which may improve the throughput of the packaging course of may additionally improve the throughput of the entire enterprise.

5. Light dealing with

After we consider palletizing robots, we regularly consider big robotic arms stacking trays of heavy packing containers. Nevertheless, many palletizing duties require a extra mild method. Light handing is especially essential with collaborative robots as they’re extra seemingly for use to pack smaller, fragile objects.

Why vacuum grippers are the best choice for robotic palletizing

Once you have a look at the properties of vacuum grippers, it is clear why they’re so nicely suited to palletizing duties. Their options match the necessities nearly precisely! The nice good thing about that is it means you do not have to fiddle round to get the gripper to work together with your process — every thing ought to simply work simply out of the field.

1. Orientation

Vacuum grippers can work in any orientation. Nevertheless, they are most effective when the lifting force is directly opposite to the force of gravity. That is excellent for palletizing as a result of it means that you’re utilizing the gripper at its most optimum.

2. Distributed payload

Though vacuum grippers can be utilized with a single suction cup, it’s extra widespread for them to incorporate a number of suction cups organized in an everyday sample. This permits them to distribute the payload over the whole floor of the thing, which is precisely what you want for palletizing.

three. Customizable

The association of suction cups is completely as much as you. For instance, our EPick and AirPick grippers include a couple of default configurations however you’ll be able to customise these very simply to precisely go well with the structure of the objects that you could palletize.

four. Quick response

Vacuum grippers are likely to have quicker response instances than comparable fingered grippers. It is because you need not look ahead to the gripper fingers to shut to select up the thing. This speedy response time will scale back the cycle time, which finally improves the throughput of the whole robotic cell.

5. Light dealing with

There’s a motive why vacuum grippers are so widespread within the meals business — they’re extraordinarily mild. Suction cups can simply deal with any delicate and fragile objects, e.g. cookies, digital chips, or glass. As this one of many key necessities for palletizing duties, it makes vacuum grippers the proper choice.

Different choices and the way they stack up

After all, vacuum grippers aren’t the one robotic finish effectors that are appropriate for palletizing duties.

Listed below are a couple of different widespread choices:

  • Fingered grippers — You are able to do most issues with a fingered gripper. Nevertheless, the primary downside for palletizing duties is you could solely elevate one object at a time, which considerably slows down the duty. A dual gripper can help however the throughput can nonetheless be fairly low.
  • Clawed grippers — A typical gripper for big industrial palletizing is the claw gripper (e.g. this one from ABB). It permits the robotic to help the burden of heavy, deformable objects with very porous surfaces (e.g. baggage of grain). Nevertheless, it is not so helpful for small palletizing duties with gentle objects.
  • Magnetic grippers — Magnetic grippers share some of the same benefits of vacuum grippers (e.g. they solely require one floor and have a quick response time). Nevertheless, a serious drawback is that they’ll solely be used with ferromagnetic supplies.
  • Customized grippers — Numerous palletizing duties use closely personalized or custom-built grippers that are designed for the precise utility. Though which means the gripper completely fits the duty, it may be expensive and time-consuming, and they are often laborious to change when the wants of the duty change.

Find out how to get began with vacuum gripper palletizing

Palletizing is de facto the proper process for vacuum grippers. To get began your self, it may be useful to be taught a bit extra about vacuum grippers and the way they work.
