Description:
We need a box stacker designed

We want you to build a simple box stacker that goes over a conveyor belt. We are willing to purchase a few of these, we will purchase a top labeler to install on top of the conveyor. We will not purchase the ocnveyor from you.

Here are two video you can look at

#4 Fully adjustable box stacker (rev1) by Akang Igun
For all box, effective size range; W= 3~6 , L = 6~14.5. If you want to use bigger box, just replace each adjuster by longer one

#3 Modular box stacker with cartridges by Bogdan Andrei
The system comprises in a main frame attached to the T-slots on the conveyor, on which different sized cartridges will fit - accordingly with the box dimansions required for work-shift. Hving multiple cartridges for each box dimension/size, will allow operators to fill the stacker with empty boxes apart from the feeding line/conveyor. This way, the changing time is reduced substantialy, increasing productivity.
The model is designed to be made from almost any kind of material (ABS, plastic sheet, metal sheet) requiring only cutting, bending and assembling (by thermal gluing, point welding or riveting).

#7 Simple Box Stacker by Dominique
Simple and rigid design.
Uses 2 kind of materials, L angles and threaded rod, No welding required and no laser cut parts reducing the cost of fabrication to its minimal
Can easily be made by any machine shop
Can contain up to 45 boxes
Attaches to the conveyor T-Slot

I don't have AUTOCAD and primarily use Solidworks. I can send you and IGES/STEP file. Will that suffice?

Hi Ash,

Several questions:
- do you use just 3 standardized boxes type? or it is possible in time to have other dimensions?
- how many boxes are used per work shift?
- how the stacker is filled with empty boxes?
- how long it takes the conveyor to empty the stacker (as you rectify - for 45 boxes)?
- this stacker is for retrofitting your conveyor or for mass production? (for retrofitting you'll need a cheaper solution, while for mass production you may optin for a bettersolution, which could be a little more expensive than the retrofitting)
- if the conveyor belt is cleated, could interfere with the bottom bends of the stacker - is better to have a different solution then cleated belt (flat belt with an adjustable guide on the side which to align the boxes)
(Could you open a private msg channel - there are several few questions which I'd like to ask)

Yes at 70 boxes it is hard for operator to fill the stacker, lets make it 45.
If you can think of a way you can stack more boxes without increasing the height , please let me know that is definitely something we would like to add but cant figure it out. Otherwise just keep it at 45

Hi, ashpdx
Just wish to confirm that the stacker need to hold 70 boxes? 1.25" x 70 = 87.5"(2.222m) total height? I guess it is not practical for the operator manual loading for that high. Kindly consider giving us the max and min weight for a box.

OK, I'll try realize the idea....
and.. when will you realize the good news "increasing the payout for this project". the number has not changed yet :)

The conveyor we will use will be 144 inches long and 12 inches wide, so the stacker base will need to be a little larger than 12 inches. something like 13.5 inches so it can hook onto the t-slot. http://screencast.com/t/H6SeyeD5T5
Also, you should be able to raise and lower the stacker by 4 inches, that way it can be adjusted so it can scoop the box with the cleats of the conveyor.

The Stacker should site on top of the conveyor and will be attached via a tslot like on this image http://screencast.com/t/riTxPWy45F
. The belt on the conveyor will be cleated, like this one http://www.mini-mover.com/images/low_profile-lp-series/lp-belt-options.jpg but the cleats will be shorter, 1.5" H by 2" W. So the cleats will go under the stacker and grab a box put it on the conveyor and the next box will be ready to get scooped

Hi ashpdx, thank you for your response
how do you want to place the stacker over the conveyor? just put it on the top frame? fixed to the frame using fastener? or ....??

I will be increasing the payout for this project.
Here is additional info that needs to be included in this project
1, size of box that goes into the stacker needs to be adjustable
size box # 1 : 6 L x 3 W x 1.25 H
size box # 2 : 7.5 L x 6 W X 1.25 H
size box # 3 : 14.5 L x 3 W x 1.25 H
2, At the bottom of the box, there should be a 90 deg bent like what Akang Igun did http://screencast.com/t/2JpK8tUxMgmX

Hi, I am interested to know more:
1) Any pneumatic cylinder brand you preferred?
2) Any sensor brand you preferred?
3) How much is the belt conveyor width (Body width) for mounting purpose?

Design a new Step Stool
The challenge is to design a new and improved Step Stool than those in the market place. Pls note: Step Stools are different from Step Ladders. Step Stools usually have 2-Steps or 3-Steps, are lightweight, slim in profile, used inside the home, are usually kept in the kitchen or closet. Ladders often have more than 3 steps, are more heavy, used for big projects, and are stored in the garage or outdoor shed. Attached is a PDF showing some of step stools now selling in the market. The best selling ones are on the first page, and they are 1) lower cost, 2) basic & simple in design and construction (that's how they are low cost), 3) but they usually have boring white frame with black steps. The better designed step stools on page-2 are 1) stylish looking, 2) some are very slim (take up less storage space), 3) some have handles that extend to help balance the user to prevent falls, while others 4) include cut outs on the step to help user "lean" to keep balance, and still others 5) include trays to hold tools. A key concern with Step Stools is SAFETY. Many injuries occur due to poor quality/design/engineer or user lose their balance when over reaching. The winning design will help prevent falls and injuries.
Design A New Way to Wring A Sponge Mop Dry
We're looking for a new and smart way to wring out water from a sponge mop. Currently, there are several methods in the market, including two popular solutions: the Butterfly Sponge Mop folds the sponge head in half to squeeze out water, and the Roller Sponge Mop pushes a round mop heap between two sets of rollers. Reference images of these two methods are included. There are endless versions of these two methods selling all over the world. We're looking for a better and smarter solution that's not only fresh looking but superior in effectiveness than these existing methods.
