Accumulation system and method

An accumulator for receiving and collecting batches of items being dispensed for facilitating subsequent processing of collected batches, the accumulator comprising:

• a) a tubular body having spaced pairs of side and end walls delineating a through passage with input and output ends;
• b) a baffle member movably mounted in the passage and having a lateral dimension slightly less than but substantially equal to the width of the passage between the end walls;
• c) a baffle support pivotally mounted on the body at a mounting location above the outlet when the accumulator is in use;
• d) the baffle support pivotally supporting the baffle at a pivot location below the outlet when the accumulator is in use;
• e) a first prime mover mechanism operably connected to the body and the support for selectively shifting the support between a first position wherein the pivot location is near one of the side walls and a second position wherein the pivot location near the other of the side walls;
• and,
• f) a second prime mover mechanism for selectively causing pivotal movement of the baffle between a first position adjacent the one side wall and a second position across the passage and between a third position adjacent the other side wall and a fourth position across the passage.

A method of collecting dispensed items in batches of predetermined numbers comprising:

• a) serially and continuously dispensing and counting items;
• b) gravity feeding dispensed items into an accumulator;
• c) allowing dispensed items to pass through the accumulator until a first batch of a predetermined number of items has been counted;
• d) as a last item of the first batch is being fed, shifting a diverter from an at least one discharge position to a collection position to divert subsequently dispensed items into a collection location within the accumulator;
• e) collecting dispensed items in the collection location until a second batch of a predetermined number of items is collected;
• f) as items of the second batch are being fed, shifting the diverter from its collection position to one said an at least one discharge position;
• g) as the last item of the second batch is being fed shifting the diverter to a further collection position to divert subsequently dispensed items into another collection location within the accumulator;
• and,
• h) sequentially repeating steps (d), (e), (f) and (g).

A method of accumulating batches of items fed serially from a dispenser to sequentially supplied batch receiving receptacles comprising:

• a) discharging items sequentially from the dispenser into a tubular accumulator having a through passage and a diverter within the passage;
• b) positioning the diverter adjacent a first wall section of the accumulator to allow a first batch of items to pass through the accumulator to a positioned receptacle;
• c) as the last item of the first batch passes through the accumulator shifting the diverter to a position across the passage to accumulate a second batch within the accumulator;
• d) positioning a second receptacle to receive the second batch and thereafter shifting the diverter to position it adjacent another wall section and discharge the second batch into the second receptacle;
• e) as the last item of the second batch passes through the accumulator shifting the diverter to a further position across the passage to accumulate a third batch within the accumulator;
• f) positioning a third receptacle to receive the third batch and thereafter shifting the diverter to position it adjacent the first wall section and discharge the third batch into the third receptacle;
• and
• g) thereafter repeating steps (b), (c), (d), (e) and (f) to sequentially accumulate further batches.

A system for sequentially establishing batches of predetermined numbers of items comprising:

• a) a feeder for continuously dispensing items serially and one at a time;
• b) a counter for counting items as they are dispensed by the feeder and emitting a batch control signal each time a predetermined number of items has been dispensed by the feeder;
• c) a tubular item separator defining a through passage for separating items fed on a continuous basis into batches, the separator including a diverter being pivotally mounted externally of the passage and extending into the passage for diverting items forming each succeeding batch to collection locations within the passage but separated from items of the batch immediately preceding each separated batch while maintaining all items along a flow path from the feeder through the passage and through a single passage outlet to a collection station, the diverter being operative to establish diversion of items of a succeeding batch in response to each such batch control signal;
• and,
• d) collection means at the collection station for sequentially collecting such batches and maintaining them in such separated condition.

A batch separator for establishing batches of predetermined numbers of items dispensed serially from a feeder for sequential deposit in batches at a collection station, the improved separator comprising:

• a) an apertured tube defining a through passage, the tube being for positioning around a single item path of travel from the feeder to the station;
• b) a diverter mounted in the tube, the diverter being shiftable between a flow position out of the path and a collection position obstructing the path, the diverter when in the flow position permitting the flow of items to the station and when in the collection position interrupting such flow to accumulate a batch of a predetermined number of items within the tube;
• and,
• c) the diverter being connectable to a prime mover for shifting between its positions.

A separator for substantially continuously receiving serially dispensed items and separating the items into batches each containing a predetermined measure of items comprising:

• a) an open ended tubular housing having a through opening defined in part by a spaced pair of side walls;
• b) a diverter having at least a section positioned within the opening;
• and,
• c) the section having:
• i) a first position adjacent one of the side walls;
• ii) a second position adjacent the other of the side walls;
• iii) a third position extending across the opening from a location near a first end of the one side wall to a location near a second end of the other side wall;
• and,
• d) a fourth position extending across the opening from a location near a first end of the other side wall to a location near a second end of the one side wall.

• d) the baffle support pivotally supporting the baffle at a pivot location below the outlet when the accumulator is in use.
