Abstract

A component supply management system includes a threshold setting portion, a remaining-amount detection portion, a determination portion, and a notification portion. The threshold setting portion sets a threshold with respect to a remaining amount capable of being supplied by the carrier tape, for each of the tape feeders, depending on types of the tape feeders. The remaining-amount detection portion detects a remaining amount of components capable of being supplied by the carrier tape, for each of the tape feeders. The determination portion determines whether the remaining amount detected by the remaining-amount detection portion is lower than the threshold set in the threshold setting portion, for each of the tape feeders. The notification portion issues a warning for recommending replenishment of a carrier tape for the tape feeder in which the determination portion determines that the remaining amount is lower than the threshold.

First claim

What is claimed is:

1. A component supply management system managing a component supply state of a tape feeder that allows a carrier tape inserted from a tape insertion port to travel so as to supply a component held in the carrier tape to a component supply position, the system comprising:
a threshold input screen that sets a respective threshold with respect to a remaining amount of components capable of being supplied by the carrier tape, for each of the tape feeders, depending on types of the tape feeders, each different type of the tape feeders having different respective thresholds;
a remaining-amount detection portion that detects a remaining amount of components capable of being supplied by the carrier tape, based on a remaining length of the tape, for each of the tape feeders;
a control device that determines whether the remaining amount of components capable of being supplied, based on the detection of the remaining-amount detection portion, is lower than the respective threshold set in the threshold input screen, for each of the tape feeders, depending on types of the tape feeders; and
a notification portion that issues a warning for recommending replenishment of the carrier tape for the tape feeder in which the control device determines that the remaining amount of components capable of being supplied is lower than the threshold.

2. The component supply management system of claim 1 ,
wherein the types of the tape feeders include:
a splicing feeder that requires splicing of a following carrier tape among the carrier tapes, which follows into a preceding carrier tape among the carrier tapes, when the following carrier tape is allowed to travel continuously to the preceding carrier tape; and
a non-splicing feeder that does not require splicing of a following carrier tape among the carrier tapes, which follows into a preceding carrier tape among the carrier tapes, when the following carrier tape is allowed to travel continuously to the preceding carrier tape.

3. The component supply management system of claim 2 ,
wherein the threshold input screen sets both a threshold of the splicing feeder and a threshold of the non-splicing feeder.

4. The component supply management system of claim 1 ,
wherein the remaining amount of components capable of being supplied by the carrier tape and the threshold are defined by a remaining number of the components held in the carrier tape or a remaining length of the carrier tape.

5. The component supply management system of claim 1 , further comprising a tape presence detector that detects whether the carrier tape is present at a position of the tape insertion port,
wherein the notification portion notifies a warning for recommending replenishment of the carrier tape when the tape presence detector detects that the carrier tape is not present at the position of the tape insertion port.

6. A component supply management method for managing a component supply state of a tape feeder that allows a carrier tape inserted from a tape insertion port to travel so as to supply a component held in the carrier tape to a component supply position, the method comprising:
a threshold setting step of setting a respective threshold with respect to a remaining amount of components capable of being supplied by the carrier tape, for each of the tape feeders, depending on types of the tape feeders on a threshold input screen, each different type of the tape feeders having different respective thresholds;
a remaining amount detection step of detecting a remaining amount of components capable of being supplied by the carrier tape, based on a remaining length of the tape, for each of the tape feeders by a remaining-amount detection portion;
a determination step of determining whether the remaining amount of components capable of being supplied by a control device, based on the detection of the remaining-amount detection step, is lower than the threshold set in the threshold setting step, for each of the tape feeders, depending on types of the tape feeders; and
a tape replenishment notification step of issuing a warning for recommending replenishment of the carrier tape with respect to the tape feeder by a notification portion in which it is determined in the determination step that the remaining amount of components capable of being supplied is lower than the threshold.

7. The component supply management method of claim 6 ,
wherein the types of the tape feeders include:
a splicing feeder that requires splicing of a following carrier tape among the carrier tapes, which follows into a preceding carrier tape among the carrier tapes, when the following carrier tape is allowed to travel continuously to the preceding carrier tape; and
a non-splicing feeder that does not require splicing of a following carrier tape among the carrier tapes, which follows into a preceding carrier tape among the carrier tapes, when the following carrier tape is allowed to travel continuously to the carrier tape.

8. The component supply management method of claim 7 ,
wherein the threshold input screen sets both a threshold of the splicing feeder and a threshold of the non-splicing feeder.

9. The component supply management method of claim 6 ,
wherein the remaining amount of components capable of being supplied by the carrier tape and the threshold are defined by a remaining number of the components held in the carrier tape or a remaining length of the carrier tape.

10. The component supply management method of claim 6 , further comprising:
a tape presence detection step of detecting whether the carrier tape is present at a position of the tape insertion port, and
a component depletion notification step of notifying component depletion when the tape presence detection step detects that the carrier tape is not present at the position of the tape insertion port.

11. A component supply management system managing a component supply state of a tape feeder that allows a carrier tape inserted from a tape insertion port to travel so as to supply a component held in the carrier tape to a component supply position, the system comprising:
a threshold input screen that sets a threshold with respect to a remaining amount capable of being supplied by the carrier tape, for each of the tape feeders, depending on types of the tape feeders;
a remaining-amount detection portion that detects a remaining amount of components capable of being supplied by the carrier tape, based on a remaining number of components, for each of the tape feeders, depending on types of the tape feeders;
a control device that determines whether the remaining amount of components capable of being supplied, detected by the remaining-amount detection portion, is lower than the threshold set in the threshold input screen, for each of the tape feeders;
a notification portion that issues a warning for recommending replenishment of the carrier tape for the tape feeder in which the control device determines that the remaining amount of components capable of being supplied is lower than the threshold further comprising a tape presence detector that detects whether the carrier tape is present at a position of the tape insertion port, wherein the notification portion notifies a warning for recommending replenishment of the carrier tape when the tape presence detector detects that the carrier tape is not present at the position of the tape insertion port.

12. A component supply management method for managing a component supply state of a tape feeder that allows a carrier tape inserted from a tape insertion port to travel so as to supply a component held in the carrier tape to a component supply position, the method comp
