Abstract

A non-splicing feeder for which new carrier tape can be set safely is provided. The feeder includes a third sprocket rotatably provided on the insertion section of a main body, a fourth sprocket rotatably provided upstream from the third sprocket in the conveyance direction; third engaging protrusions which engage with engaging holes which are formed at a fixed angle on the outer circumference of a first sprocket, and fourth engaging protrusions which engage with engaging holes which are formed at only a portion of the outer circumference of the fourth sprocket.

First claim

The invention claimed is:

1. A feeder for inserting carrier tape, in which many components are successively stored in a conveyance direction and in which engaging holes which have a prescribed relationship with the components are formed at a regular pitch interval in the conveyance direction, into an insertion section, and feeding the carrier tape such that the components are sequentially supplied to a supply position on a side opposite to the insertion section, the feeder comprising:
a main body;
a downstream sprocket rotatably provided on the insertion section of the main body; and
an upstream sprocket rotatably provided further upstream in the conveyance direction than the downstream sprocket;
wherein downstream engaging protrusions that engage with the engaging holes are formed at a fixed angle around an entire outer circumference of the downstream sprocket; and
wherein upstream engaging protrusions that engage with the engaging holes are formed at a fixed angle around a first portion of an outer circumference of the upstream sprocket, a second portion of the outer circumference of the upstream sprocket is free of the upstream engaging protrusions, and a circumferential distance of the second portion of the outer circumference of the upstream sprocket is greater than a circumferential distance of the first portion of the outer circumference of the upstream sprocket.

2. The feeder according to claim 1 , wherein a motor is provided on the main body, the motor synchronously rotating the downstream sprocket and the upstream sprocket.

3. The feeder according to claim 2 , further comprising a gear which is driven by the motor, the gear meshing with both a sprocket gear of the downstream sprocket and a sprocket gear of the upstream sprocket.
