Abstract

A component supplying apparatus includes a main tape entering port, a component supply port through which components are picked up from a carrier tape, a main tape path extending in a body part from the main tape entering port to the underside of the component supply port, a top tape removing part removing the top tape from the carrier tape on the main tape path upstream of the component supply port, a sub tape entering port, a sub tape path meeting a slope path portion of the main tape path at a meeting point upstream of the top tape removing part, and at least one sprocket wheels engaging with the carrier tape on the main tape path downstream of the meeting point. A length of the sub tape path is shorter than a length of the main tape path from the main tape entering port to the meeting point.

First claim

The invention claimed is:

1. A component supplying apparatus for feeding in a tape length direction a carrier tape having a base tape having recesses for accommodating components and feed holes arranged thereon in the tape length direction and a top tape pasted on the base tape so as to cover the recesses, the component supplying apparatus comprising:
a body part,
a main tape entering port formed on the body part,
a component supply port formed on an upper surface of the body part and through which nozzles of a transfer head of a component mounting apparatus pick up the components in the recesses of the carrier tape having been entered from the main tape entering port,
a main tape path extending in the body part from the main tape entering port to under the component supply port,
a tape feeding device feeding the carrier tape toward the component supply port along the main tape path,
a top tape removing part removing the top tape from the base tape of the carrier tape on the main tape path upstream in a tape feeding direction of the component supply port so as to expose the components in the recesses, and
a sub tape entering port formed on the upper surface of the body part and adapted to be entered by the carrier tape so as to enter the carrier tape into the main tape path,
wherein a path length from the sub tape entering port to the component supply port is shorter than a path length from the main tape entering port to the component supply port.

2. The component supplying apparatus according to claim 1 , wherein the tape feeding device feeds the carrier tape having been entered in the sub tape entering port from the top tape removing part to the component supply port.

3. The component supplying apparatus according to claim 1 , wherein the tape feeding device has at least one sprocket wheel engaging with the feed holes of the carrier tape on the main tape path and feeding the carrier tape in the tape feeding direction.

4. The component supplying apparatus according to claim 1 , further comprising a sub tape path extending in the body part from the sub tape entering port and meeting the main tape path at a meeting point midstream of the main tape path.

5. The component supplying apparatus according to claim 1 , wherein the main tape entering port has a size enough for two carrier tapes overlapping each other in a thickness direction to enter, and
further comprising an automatic feeding device that, until a rear end in the tape feeding direction of one of the two carrier tapes having been entered into the main tape entering port and overlapped with each other passes beyond a front end in the tape feeding direction of another of the two carrier tapes, keeps the other carrier tape waiting in the main tape path between the main tape entering port and a meeting point.

6. The component supplying method for feeding in a tape length direction a carrier tape having a base tape having recesses accommodating components and feed holes respectively arranged thereon in the tape length direction and a top tape pasted on the base tape so as to cover the recesses, the component supplying method comprising:
entering the carrier tape into a body part of a component supplying apparatus through a main tape entering port,
feeding the carrier tape having been entered into the body part in a tape feeding direction along a main tape path extending in the body part from the main tape entering port to under a component supply port,
removing the top tape from the base tape of the carrier tape on the main tape path upstream in the tape feeding direction of the component supply port so as to expose the components in the recesses, and
picking up the components in the recesses of the carrier tape with the top tape removed through the component supply port by using nozzles of a transfer head of a component mounting apparatus, and
further comprising, in case that the carrier tape has a length shorter than a distance of the main tape path from the main tape entering port to the component supply port:
entering the shorter carrier tape into the main tape path from a sub tape entering port formed on an upper surface of the body part,
feeding the shorter carrier tape having been entered into the main tape path from the sub tape entering port along the main tape path in the tape feeding direction,
removing the top tape from the base tape of the shorter carrier tape on the main tape path upstream in the tape feeding direction of the component supply port so as to expose the components in the recesses, and
picking up the components in the recesses of the shorter carrier tape with the top tape removed through the component supply port by using the nozzles of the transfer head of the component mounting apparatus.
