Abstract

A tape feeder includes a tape guideway that has an insertion port, a first tape transporter that transports a leading tape to a component extraction position in the tape guideway, a second tape transporter that transports the following tape from the insertion port to the first tape transporter, a following tape holder that has a first supporter that supports one side of an uninserted portion of the following tape in a width direction from a lower side, and a second supporter that supports the other side of the uninserted portion in a width direction from the lower side, and holds the uninserted portion of the following tape, and a displacer that displaces the uninserted portion of the following tape from the following tape holder. A width of one end portion of the second supporter decreases toward the insertion port.

First claim

What is claimed is:

1. A tape feeder that is used in a component mounting device for installing a component on a board, the component being held by a mounting head, transports a carrier tape containing the component, and supplies the component to a component extraction position by the mounting head, the tape feeder comprising:
a tape guideway that has an insertion port into which a leading tape and a following tape can be inserted, the following tape being a carrier tape fed after the leading tape;
a first tape transporter that is provided on a downstream side of the tape guideway, and transports the leading tape to the component extraction position in the tape guideway;
a second tape transporter that is provided on an upstream side of the tape guideway, and transports the following tape from the insertion port to the first tape transporter;
a following tape holder that has a first supporter that supports one side of an uninserted portion of the following tape not inserted into the insertion port in a width direction from a lower side, and a second supporter that supports the other side of the uninserted portion in a width direction from the lower side, and holds the uninserted portion of the following tape at a position separated upward from an uninserted portion of the leading tape; and
a displacer that displaces a position of the second supporter upward with respect to the first supporter, and displaces the uninserted portion of the following tape from the following tape holder,
wherein a width of one end portion of the second supporter decreases toward the insertion port.

2. The tape feeder of claim 1 ,
wherein the following tape holder has a guide surface that guides one side surface of the following tape in the width direction, and a plate-shaped member in which the first supporter is formed, and
wherein the displacer has a guide surface that guides the other side surface of the following tape in the width direction, and a movable member that has the second supporter formed therein and is vertically displaceable with respect to the plate-shaped member.

3. The tape feeder of claim 2 ,
wherein the movable member is swingable about a horizontal shaft, and
wherein the displacer has a spring for urging the movable member downward, and a stopper that positions the second supporter at the same height as a height of the first supporter by regulating downward displacement of the movable member.

4. The tape feeder of claim 2 ,
wherein the plate-shaped member has a protrusion that is formed at a position separated upward from the first supporter.

5. The tape feeder of claim 4 ,
wherein a width of a lower end portion of the protrusion in a horizontal direction decreases as the protrusion goes downward.

6. The tape feeder of claim 2 ,
wherein the movable member has a one-way clutch, and a sprocket mounted on a shaft through the one-way clutch, and
wherein the one-way clutch permits rotation of the sprocket when the following tape moves on the following tape holder in a direction toward the insertion port, but does not permit rotation of the sprocket when the following tape moves on the following tape holder in an opposite direction to the direction toward the insertion port.
