Design / Blueprint Resorting recycled Scrap Inserter friendly

Somehow my train station were struggling to process recycle belts and until 2 days ago, I was bothered, but did not understand why. Turns out the item randomness turns Bulk and Fast inserters into single item inserters. So I wanted to reorganize the belts to be inserter friendly.

Task: Resort a random (blue) belt into matching chunks.

Sidenotes:

  • The Quality of sorting could be measured by the numbers of bulk inserters emptying the sorted belt. E.g. unsorterted it might be around 20 - a belt of Iron would only need 4. So the lower the better
  • A priority splitter at the start checks for backlog. If the belt stalls
  • Chests should either be filled XOR emptied - as both can lead to items getting stuck - Inserters seem to LIFO (last in first out).
  • Mods: I used Nixie Tubes for numbers and AAI Containers & Warehouses to gain a larger chests.

First Iternation

Plan seemed straight forward - use 2 somewhat large chests and swap insert/empty cycles.

You can still see the 2x 4x4 Storehouses (A/B) with whom I started out and then it sent a bit further. Turns out that 12 Fast Inserters are not enough to empty a blue belt. I tried using filters on the most common items and reducing the stacksize to 1/2 for the rest, but still in bad constellations, items got past and would clog up the belt. So I added a 2x2 Strongbox (C) - which postponed trouble as the belt would run over if the box was getting emptied. So 2x alternating Storehouses (A/B) and 2 alternating Strongboxes (C/D).

Problem was I never was able to saturate the outgoing belt at all times. At least two boxes would need to empty, but sometimes it was only one resulting in a slow buildup, but it will overflow.

  • Alternating lane filler. The idea was that a lane gets filled, once it exceeds a threshold it gets emptied and the other lane gets filled. Worked semi well, but It was the idea for a second attempt to use Splitters instead of inserters

Splitters and alternating Lanes

So I used Splitters with filters set to the Recyling product - left the lowest - right the highest. Due Stalling I needed a bypass lane. Idea was for each double land one would be filled up and when it empties- the other lane fills - so each item gets released as one massive block as inserters work best the lower the variety is. The double lane to prevent stalling. Problem is releasing the sorted bunch as one continuous stream - this setup has a hickup maybe every 30 minutes.

--------------

V3 was Train Wagons - messy as you have to copy them with trains and not useful as you cannot monitor the Wagon via circuit network by default. I tried with continous insertion / removal, but this results in an item swamp(?) - items stuck that never get removed as new stuff is piled on top.

-------------------

V4 Double Warehouse

I did not want to use Warehouses (6x6 Chests) because they were so big. But as you can see the other tries were not merely small.

Top left fail indicator - simple Item detection on the overflow. The Chests are either filling or emptying. On the top the inserters are switched off - on the bottom just the belt. This was necessary as during transition - A loading and B emptying - the inserters at B are turned off thus the belt fills up and when A switches to B the belt is full and it causes a backlash. Even with empty belts there is a 4-5 item backlash - thus the "overpass" on the top right.

The items come out mostly homogenous. But still it is somewhat a large footprint.

P.S.: I thought the spoiler tags would collapse the blueprint strings... Sorry.

Scrap from miner on belt and train, comes to 2 recyclers that feeds out into a single train wagon. 12 filtered stack inserters, 6 per side, waits till they have a stack of same items, then place them on a belt. So 12 belts with sorted recycled scrap in stacks.

u/TheCryptomancer 16h ago

This is how I do it, except instead of train wagon into belt, it's train wagon into provider chests* (*And a secondary chest-to-belt that goes right into more recyclers).

u/Mhdamas 22h ago

In the variant where you used filter splitters to sort the recycled products wouldnt it be easier to use bulk inserters fed wit the filtered lanes and just have the output merge?.

Id use a clock to time the inserters to make sure nothing gets mixed should be a bit easier than the other methods.

u/alrun 10h ago

You might get a similar result. Each lane is sorted (except quality) and released in burts of about 60 items. Problem is merging them into a single bus without gaps. Bulk inserters will wait for an open spot, so they spread the sorted items again.

Priority merging was the stuff that might preserve the lanes as good as possible. Maybe there is a better way. But the feedback seems that this was not a useful excercise.

u/Mhdamas 8h ago

Id be surprised if a clock doesnt allow you to time the inserters so theres no gaps but maybe the blue belt moves too fast.

I can see why some people would rather just use the sorted lanes directly instead of a single sushi belt but this is far more compact and fun.
