Tape Feeder Downward Waste Tape Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tape feeders face challenges in effectively discharging waste tape after lead components are separated from a carrier tape, leading to inefficient disposal and potential jamming issues.
Innovation Solution
A tape feeder design that includes a path for linear feeding of taped components and waste tape in opposite directions, a discharge port for downward disposal, and a pushing section to intersectively guide the waste tape, along with slit-shaped openings in the wall surface to expose feeding holes, facilitating proper waste tape discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the waste tape is discharged horizontally from the tape feeder, then the discharge structure is simple, but the waste tape may entangle or jam during discharge
Solution Approach 1:
The discharge port is configured to discharge the waste tape downwardly from the tape feeder, changing the discharge direction from horizontal to vertical. This dimensional change in discharge orientation prevents the waste tape from entangling or jamming during discharge, while maintaining structural simplicity through the use of a pushing section to guide the tape into the discharge port.
2Ease of operation
If the pushing section pushes the waste tape in the direction of the path, then the discharge path is clear, but the waste tape cannot be properly oriented for discharge
Solution Approach 1:
The pushing section is divided into multiple pushing sections that push the waste tape at different positions and directions. The first pushing section pushes the waste tape in the direction of the path to clear the discharge path, while the second pushing section pushes the waste tape in a direction intersecting the path to properly orient it for downward discharge. This segmentation of pushing functions resolves both requirements.
3Adaptability or versatility
If the carrier tape width is reduced to accommodate smaller components, then the feeder can handle smaller components, but the waste tape becomes more prone to jamming
Solution Approach 1:
The discharge port discharges the waste tape downwardly from the tape feeder, changing the discharge orientation to vertical. This dimensional change in discharge direction prevents narrower waste tapes from jamming during horizontal discharge, while allowing the feeder to accommodate smaller components through reduced carrier tape width.

AI summary
A tape feeder configured to supply lead components removed from a carrier tape by cutting leads of a taped component, and discharge a waste tape outside of the tape feeder, the taped component being composed of the lead components, each having the leads, and the carrier tape holding the leads of the lead components, the waste tape being composed of remaining leads, which remain on the carrier tape after the leads are cut, and the carrier tape holding the remaining leads in a protruded state; wherein, the tape feeder further comprises: a path, inside the tape feeder, which is used for linearly feeding the taped component before cutting the leads and linearly feeding the waste tape after cutting the leads in a first direction, and then reversing to a second direction opposite to the first direction and linearly feeding in the second direction; a discharge port configured to discharge the waste tape, being fed from the downstream end of the path, downwardly from the tape feeder; and a pushing section, being provided between the downstream end of the path and the discharge port, configured to push a portion of the carrier tape of the waste tape fed from the downstream end of the path in a direction intersecting the path.
