Automatic feeder exchanging system

1. An automatic feeder exchanging system that automatically exchanges a feeder for which exchange is necessary from multiple feeders set in a feeder setting area of a component mounter, the automatic feeder exchanging system comprising:

a feeder stocking area at which a feeder to be exchanged with the feeder for which exchange is necessary stands by;

an exchange robot that pulls out the feeder for which exchange is necessary from the feeder setting area and pulls out a feeder that supplies the same components as the feeder for which exchange is necessary from the multiple feeders standing by at the feeder stock area;

a storage means that, in a case in which the feeder pulled out from the feeder setting area is a feeder with components remaining, stores a link between the component remaining quantity and the feeder; and

an exchange period setting means that sets an exchange period of each feeder set in the feeder setting area such that the exchange period of each feeder does not overlap with the exchange period of another feeder,

wherein

the exchange robot, at the exchange period set by the exchange period setting means, pulls out the feeders from the feeder setting area for which the exchange period has arrived, collects at least the feeders with components remaining into the feeder stock area, pulls out feeders that supply the same components as the feeders for which the exchange period has arrived from the multiple feeders standing by in the feeder stock area, and sets the feeders pulled out from the feeder stock area in the feeder setting area, and

the exchange period setting means, when the exchange robot sets the feeders with components remaining in the feeder setting area, sets the exchange period of the feeders with components remaining using the component remaining quantity stored in the storage means.

2. The automatic feeder exchanging system according to claim 1 , wherein

the exchange period setting means calculates the time at which components will run out for each of the feeders set in the feeder setting area, sets the exchange period of each feeder for which a component run-out time does not overlap with another feeder as the component run-out time for those feeders, sets the exchange period of only one feeder for which the component run-out time overlaps as the component run-out time, and sets the exchange period for other feeders to a time earlier than the component run-out time such that the exchange periods for each feeder do not overlap.

3. The automatic feeder exchanging system according to claim 1 , further provided with

a used feeder collection area in which used feeders for which components have been completely used up are collected,

wherein

the exchange robot, in a case in which the feeder pulled out from the feeder setting area is a used feeder, collects the used feeder in the used feeder collection area.

4. The automatic feeder exchanging system according to claim 1 , further provided with

a feeder monitoring means that monitors whether feeders that supply the same components as each of the feeders set in the feeder setting area are present in the feeder stock area, and

a guidance means that guides an operator with at least one of a display or a sound to replenish the feeder stock area with feeders that supply components for feeders of components that the feeder monitoring means has determined are not present in the feeder stock area.

5. The automatic feeder exchanging system according to claim 1 , wherein

an identification information recording section on which feeder identification information is recorded or stored is provided on the feeders,

an identification information reading section that reads the feeder identification information from the identification recording section of the feeders standing by in the feeder stock area is provided in the feeder stock area, and

a control means that controls the exchange robot identifies the feeders based on the feeder identification information sent from the identification information reading section.

6. The automatic feeder exchanging system according to claim 1 , further provided with

a feeder transport conveyor that performs loading of feeders for replenishment to the feeder stock area and unloading of used feeders, and

a switching robot that switches feeders between the conveyor and the feeder stock area.

7. The automatic feeder exchanging system according to claim 1 , wherein

the feeders are cassette-type feeders provided with

a tape loading section that loads wound component supply tape,

a tape feed mechanism that feeds component supply tape pulled out from the tape loading section to a component pickup position,

a cover tape peeling mechanism that exposes components in the component supply tape by peeling cover tape from the component supply tape forward of the component pickup position, and

a cassette case built into which are the tape loading section, the tape feed mechanism, and the cover tape peeling mechanism.
