Printed Open-Source Product Supply Counting Line - This repository contains all the STL files needed to recreate Lunchbox Electronics Fulfillment Line POPSCL In addition to the STL files: STL files for the convayor belt pullies can be found here: http://www.andymark.com/product-p/am-2234.htm STL files for the screws and nuts can be found here: http://www.mcmaster.com
All parts were printed on a Lulzbot Taz 5 with PLA or N-Gen filament
POPSCL was created to aid in the counting and packaging of Build Upons by Lunchbox Electronics. Instead of counting out a certain number of bricks and bagging them for hours, POPSCL will take bricks from a large hopper and put them one by one onto a conveyor belt to be counted. These bricks are then dropped into a bucket to be dumped into a bag by the operator.
The basic workflow of POPSCL is:
- A bunch of bricks get dumped into the hopper
- The cleated belt runs through the hopper picking bricks up one by one
- The cleated belt drops the individual bricks onto the prefeeder which is the transition to the conveyor belt.
- Once on the conveyor belt the bricks pass through a IR gate (this break of the IR beam is registered and each brick is counted as it goes by)
- The bricks then fall off the conveyor belt in a bucket on the carousel
- When the determined number of bricks per bag is reached all motors stop and the carousel rotates to fill an empty bucket with more bricks
- This process continues till there are no more bricks to bag
- All supplied 3D printed STL files
