Abstract
A parts mounting system includes a plurality of mounting units and a parts distributor unit for distributing parts to the mounting units. The parts distributor unit includes a specifying section for specifying types of parts that can be mounted by each of the mounting units, as division-specified parts, and a distributor section for sequentially distributing parts, based on the types of parts, from the parts other than the division-specified parts, to the mounting units. The distributor section sequentially distributes the division-specified parts to the mounting units so that the division-specified parts are divided thereby to reduce a difference in mounting time by each mounting unit after the parts other than division-specified parts are distributed.
Claims6
A parts mounting system, comprising:
- at least one high-speed parts mounting unit;
- at least one multi-function mounting unit for mounting parts having a plurality of different forms, said multi-function unit having a parts mounting speed less than a parts mounting speed of the high-speed parts mounting unit;
- and
- a parts distributor unit for preparing distribution data indicating parts to be distributed to each mounting unit, said parts distributor unit comprising:
- an input section for inputting parts data corresponding to parts to be distributed to each parts mounting unit;
- a first memory for storing data received from the input section;
- a second memory for storing distribution data;
- and
- a distributor section connected to said at least one high-speed mounting unit and said at least one multi-function mounting unit, said distributor section comprising:
- means for detecting data identifying division-specified parts;
- first means for storing in said second memory, distribution data for batch distribution of non-division-specified parts of a same type to each parts mounting unit;
- means for calculating a difference in mounting time among the mounting units;
- second means for storing in said second memory, distribution data for distributing division-specified parts sequentially one at a time to a parts mounting units having a shortest mounting time according to the calculated difference;
- and
- means for repeating operation of said means for calculating a difference and said second means for storing distribution data, until no division-specified parts data remain.
