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 which 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 in the body part,
a main tape path extending in the 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 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,
a sub tape entering port formed on the body part and different from the main tape entering port,
a sub tape path extending in the body port from the sub tape entering port and meeting the main tape path at a meeting point in the main tape path located upstream in the tape feeding direction of the top tape removing part, and
at least one first sprocket wheel engaging with the feed holes of the carrier tape on the main tape path downstream in the tape feeding direction of the meeting point and feeding the carrier tape in the tape feeding direction,
wherein the main tape path includes a horizontal path portion passing under the component supply port in a horizontal direction and a slope path portion extending in an obliquely upward direction toward the horizontal path portion,
wherein the sub tape path extends in an obliquely downward direction and meets the slope path portion of the main tape path, and
wherein 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.

2. The component supplying apparatus according to claim 1 , further comprising a second sprocket wheel engaging with the feed holes of the carrier tape on the main tape path between the main tape entering port and the meeting point and feeding the carrier tape in the tape feeding direction,
wherein the length of the sub tape path is shorter than a length of the main tape path from the second sprocket wheel to the meeting point.

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

4. The component supplying apparatus according to claim 1 , wherein the first sprocket wheel engages with the feed holes of the carrier tape on the main tape path between the top tape removing part and the meeting point.

5. 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 in to the body part in the tape feeding direction along a main tape path which extending in the body part from the main tape entering port to the underside of a component supply port and which including a horizontal path portion passing under the component supply port in a horizontal direction and a slope path portion extending in an obliquely upward direction toward the horizontal path portion,
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,
further comprising, in case that the carrier tape has a length shorter than the distance in the main tape path from main tape entering port to the component supply port,
feeding the shorter carrier tape in the tape feeding direction toward the component supply port along a sub tape path which extends in the body part in an obliquely downward direction from a sub tape entering port different from the main tape entering port and which meets the main tape path at a meeting point on the slope path portion of the main tape path located upstream in the tape feeding direction of the top tape removing part, by using at least one sprocket wheel engaging with the feed holes of the carrier tape on the main tape path downstream in the tape feeding direction of the meeting point,
wherein a length of the sub tape path from the sub tape entering port to the meeting point is shorter than a length of the main tape path from the main tape entering port to the meeting point.
