What items should we consider counting via a Bullet system and a standard Vacuum system?
Light Frame
A frame approximately two feet (can be in several different shapes) made of various steel or plastic materials that houses a infrared light bar which registers a count each time an item passes through the frame.
Light frames come in several configurations from the Super Basic, which only registers a count, to a system that will file a report into a spreadsheet via a PLC controller, to a system that can be connected directly to port information in both directions over a computer network. This latter system is normally used with large system of five light frames and larger.
Tube (sometimes called a Lane)
A PVC pipe normally 4" to 8" in diameter that is connected between the count station and the receiving container. Three (3) tubes are considered the maximum for a single table/operator.
Dump
The action of a receiving container (vacuum bin, bulk bin, or Bullet) dumping into a sling/cart or onto a flat belt conveyor.
A system of vacuum tubes connecting a sorting platform usually a table or conveyor, to a vacuum bin. The bin normally sits above a flat belt conveyor. These vacuum tubes house a series of infrared eyes for counting by being connected to a control panel, which is connected to a computer, which is connected to a host server computer. One standard system is considered to be one table with two bins.
Count Station Table (normally called the "Table")
A table, conveyor or other platform where items are placed (by various means) and then sorted, inspected and thrown into a suction tube or light frame device.
Count Station Operator
The person who operates the count station.
Standard Vacuum Bin
A vacuum container that receives items after sorting them on the count station. Normally the vacuum chamber in this container holds about 20 lbs of a specific item. Items going into the vacuum bin are of "like type" for each dump. Most often a vacuum bin is located over a flat belt conveyor, which receives the items dumping from the vacuum bin. Normally a 5 HP motor mounted on the bin per bin drives the vacuum.
Vacuum Buffer Bin
The "Buffer" stands for a non-vacuum secondary container mounted directly onto or beneath a Standard Vac Bin This is used to allow the operator additional space to place the current load, awaiting the conveyor to become clear under the vac bin and to free the main vac bin to begin counting the next item or account.
Vacuum Bulk Bin
This is very similar to a vacuum bin only much larger. This container houses approximately 100 lbs. (depending on the size of the item). This bin normally does not dump onto a conveyor but rather dumps directly into a sling/cart and is used for one specific item. A 10 or 15 HP motor mounted off the bin normally drives this vacuum bin.
The normal operation is to place a sling/cart below this bin and leave the bin door closed while the items being counted are vacuumed into the bin. Once the maximum quantity of pieces or pounds are reached, the bulk bin door opens, dumping the items into the awaiting sling/cart. If this dump fills the sling/cart, an alarm sounds and/or a light flashes notifying the director to replace the "full" sling/cart with an empty one.
Bullet Classifier System (the transfer backbone of a large vac system)
This is a patented product of Automation Dynamics and is very unique in its ability to have a vacuum at the count station tube, (like a standard vacuum bin) but then transfers the item inside the tube into a "blow or positive air stream." This allows the item being transported inside the tube to be "blown" directly into a sling/cart without using a vacuum bin, flat belt conveyor or sweeper. A 10 or 15 HP motor, floor or roof, normally drives this deliver/counting device.
The ability to have one operator use one vacuum tube, at their normal count station, that can deliver into any bin, out of a series of bins, connected to this one tube.
This means that one tube can be used to carry and sort several items without the need for each item to have its own dedicated tube and without dropping these items onto a conveyor belt.
Bullet Collector Bin
A non-vacuum holding bin used specifically with the Bullet Classifier System. This collector bin is used to collect and hold items of like type from each and every count station connected to this bin.
There are normally four to six (and could be as many as 99) of these bins laid out in series (or a set) one in front of the other, connected by one tube from each count station.
The normal operation is to place a sling/cart below this collector bin and leave the bin door open, while the items being counted go directly into the sling/cart. Once the required quantity of pieces or pounds are reached the collector bin door closes, an alarm sounds and a light flashes notifying the director to replace the full sling/cart with an empty one.
The count operator does not need to wait or stop counting as the items being counted begin filling the collector bin until the sling/cart is removed and replaced with an empty one.
Bullet Transition
This is the flapper style valve that directs the items into the proper Bullet Collector Bin. There is one for every table times the total number of Collector Bins (a 5 table X 4 collector bins = 20 transitions).
Sweeper
The person who removes the items from a flat belt conveyor and places them into a sling/cart.
Director
The person who moves the full sling/carts into a holding area or onto a monorail system and replaces the full sling/cart with an empty one.
