Abstract

A feeder includes a discharge guide member which is provided on a feeder main body to communicate with a tape discharging section and guides such that a carrier tape which is discharged from the tape discharging section heads downward, a peeling member which is provided on the feeder main body and peels a cover tape from the carrier tape before the carrier tape which is conveyed by a front side sprocket reaches the tape discharging section, and a contacting and positioning member which is provided on the feeder main body, causes the cover tape which covers the carrier tape which is conveyed by the front side sprocket to contact the peeling member, and positions the carrier tape from which the cover tape is peeled and which is discharged from the tape discharging section at a regular position inside the discharge guide member.

First claim

The invention claimed is:

1. A feeder comprising:
a feeder main body in which a tape insertion section for inserting a carrier tape which stores multiple components and is covered by a cover tape is formed at a rear portion of the feeder main body and a tape discharging section for discharging the carrier tape is formed at a front portion of the feeder main body;
a tape conveyance path which is provided on the feeder main body to communicate the tape insertion section and the tape discharging section and is for conveying the carrier tape from a rear toward a front;
a rear side sprocket which is provided on the feeder main body to be capable of rotating, includes engagement protrusions which are capable of engaging with engagement holes of the carrier tape which is inserted from the tape insertion section, and sequentially conveys a current carrier tape and a next carrier tape along the tape conveyance path;
a front side sprocket which is provided on the feeder main body to be capable of rotating, includes engagement protrusions which are capable of engaging with the engagement holes of the carrier tape which is conveyed by the rear side sprocket, and once conveyance of the current carrier tape to the tape discharging section is completed, conveys the next carrier tape which is conveyed thereto by the rear side sprocket to the tape discharging section;
a discharge guide member which is provided on the feeder main body to communicate with the tape discharging section and guides such that the carrier tape which is discharged from the tape discharging section heads downward;
a peeling member which is provided on the feeder main body and peels the cover tape from the carrier tape before the carrier tape which is conveyed by the front side sprocket reaches the tape discharging section; and
a contacting and positioning member which is provided on the feeder main body between the peeling member and the tape conveyance path, the contacting and positioning member pushes a lower face of the carrier tape to cause the cover tape to contact the peeling member and positions the carrier tape from which the cover tape is peeled to be discharged from the tape discharging section.

2. The feeder according to claim 1 ,
wherein the discharge guide member guides an upper face of the carrier tape, and
wherein the contacting and positioning member positions the carrier tape inside the discharge guide member by pushing up the lower face of the carrier tape to push the upper face of the carrier tape onto the discharge guide member.

3. The feeder according to claim 1 ,
wherein the contacting and positioning member is formed in a plate shape, and the contacting and positioning member causes the cover tape to contact the peeling member at a portion of a tape conveyance upstream side, and positions the carrier tape inside the discharge guide member at a portion of a tape conveyance downstream side.

4. The feeder according to claim 3 ,
wherein the contacting and positioning member is formed such that an upstream side end portion of the tape conveyance upstream side is locked in the tape conveyance path and a downstream side end portion of the tape conveyance downstream side extends more to the front than the tape discharging section to enter into the discharge guide member; and
wherein the contacting and positioning member pushes up the lower face of the carrier tape using a portion of the tape conveyance upstream side and using the upstream side end portion as a fulcrum, causes the cover tape to contact the peeling member, pushes up the lower face of the carrier tape using the downstream side end portion, and positions the carrier tape inside the discharge guide member.

5. The feeder according to claim 1 , further comprising:
a first pair of springs that bias the contacting and positioning member towards the peeling member.

6. The feeder according to claim 5 ,
wherein the peeling member includes a blade that peels the cover tape from the carrier tape, and
wherein a first spring of the first pair of springs is upstream of the blade and a second spring of the first pair of springs is downstream of the blade.

7. The feeder according to claim 6 , further comprising:
a second pair of springs that bias the contacting and positioning member towards the peeling member,
wherein the second pair of springs are downstream of the first pair of springs, and
wherein an elastic force of the second pair of springs is greater than an elastic force of the first pair of springs.

8. The feeder according to claim 1 ,
wherein an upstream side end portion of the contacting and positioning member is locked inside a groove provided in the tape conveyance path.
