Abstract

A component supply system of the present disclosure includes a component supply unit automatically transfers a first carrier tape which stores components and is covered with a cover tape, exposes the components from the first carrier tape using a component exposing unit, and supplies the components which are exposed from the first carrier tape, a joining determination unit which determines whether or not a joining which joins a second carrier tape positioned behind the first carrier tape to the first carrier tape is present, and a controller which controls transferring of the first carrier tape by the component supply unit. The controller restricts the transferring of the first carrier tape in a case in which the joining determination unit determines that the joining is present.

First claim

What is claimed is:

1. A component supply system, comprising:
a component supply unit that automatically transfers a first carrier tape which stores components and is covered with a cover tape, exposes the components from the first carrier tape using a component exposing unit, and supplies the components which are exposed from the first carrier tape;
a joining determination unit which determines whether or not a joining is present, wherein the joining is a joint, formed by splicing, that joins the first carrier tape to a second carrier tape positioned behind the first carrier tape; and
a controller which controls transferring of the first carrier tape by the component supply unit,
wherein the controller restricts the transferring of the first carrier tape in a case in which the joining determination unit determines that the joining is present,
wherein the component supply unit includes a sensor which detects the joining mid way down a transfer path of the first carrier tape at a position in front of the component exposing unit,
wherein the joining determination unit determines whether or not the joining is present based on detection information of the sensor, and
wherein the controller stops transferring of the first carrier tape at a position at which the joining is in front of the component exposing unit in the case in which the joining determination unit determines that the joining is present.

2. The component supply system of claim 1 , further comprising:
a reader which reads identification information attached to a reel which stores the first carrier tape;
a storage which associates and stores the identification information attached to the reel with presence or absence of the joining; and
a notification unit which performs notification of an occurrence of an abnormality,
wherein the joining determination unit determines whether or not the joining is present based on the identification information which is read by the reader and information stored in the storage, and
wherein the controller causes the notification unit to perform notification of a warning in the case in which the joining determination unit determines that the joining is present.

3. The component supply system of claim 1 ,
wherein the joining is transferred to a visible position in the case in which the joining determination unit determines that the joining is present.

4. The component supply system of claim 1 ,
wherein the sensor is a transmitting sensor which detects a light blocking state of the first carrier tape,
wherein the component supply unit further includes a computer which computes a light blocking length in the case in which the light blocking state is detected by the sensor, and
wherein the joining determination unit determines that the joining is present in a the case in which the light blocking length exceeds a threshold.

5. The component supply system of claim 1 ,
wherein the controller inhibits the forward transferring of the first carrier tape in the case in which the joining determination unit determines that the joining is present.

6. The component supply system of claim 5 ,
wherein the controller restricts transfer of the first carrier tape such that the joining is not transferred to the component exposing unit in the case in which the joining determination unit determines that the joining is present.

7. The component supply system of claim 6 ,
wherein the joining is transferred using a reverse rotation mode to an upstream side of an insertion port of the component supply unit.

8. The component supply system of claim 6 ,
wherein the joining is transferred using a forward rotation mode to the position in front of the component exposing unit in the case in which the joining determination unit determines that the joining is present.

9. A component supply method in a component supply system including a component supply unit automatically transfers a first carrier tape which stores components and is covered with a cover tape, exposes the components from the first carrier tape using a component exposing unit, and supplies the components which are exposed from the first carrier tape, the method comprising:
determining whether or not a joining is present, wherein the joining is a joint, formed by splicing, that joins the first carrier tape to a second carrier tape positioned behind the first carrier tape; and
restricting transferring of the first carrier tape in a case in which the joining is determined to be present,
wherein the component supply unit includes a sensor which detects the joining mid way down a transfer path of the first carrier tape at a position in front of the component exposing unit,
wherein a joining determination unit determines whether or not the joining is present based on detection information of the sensor, and
wherein a controller stops transferring of the first carrier tape at a position at which the joining is in front of the component exposing unit in the case in which the joining determination unit determines that the joining is present.

10. The component supply method of claim 9 ,
wherein the component supply system further includes
a reader which reads identification information attached to a reel which stores the first carrier tape,
a storage which associates and stores the identification information of the reel with presence or absence of the joining, and
a notification unit which performs notification of a warning,
wherein it is determined whether or not the joining is present based on the identification information which is read by the reader and information stored in the storage, and
wherein the notification unit performs notification of the warning in a the case in which the joining is determined to be present.

11. The component supply method of claim 9 ,
wherein the joining is transferred to a visible position in the case in which the joining is determined to be present.

12. The component supply method of claim 9 ,
wherein forward transfer of the first carrier tape is inhibited in the case in which the joining is determined to be present.

13. The component supply method of claim 12 ,
wherein transfer of the first carrier tape is restricted such that the joining is not transferred to the component exposing unit in the case in which the joining is determined to be present.

14. The component supply method of claim 13 ,
wherein the joining is transferred using a reverse rotation mode to an upstream side of an insertion port of the component supply unit in the case in which the joining is determined to be present.

15. The component supply method of claim 13 ,
wherein the joining is transferred using a forward rotation mode to the position in front of the component exposing unit in the case in which the joining is determined to be present.
