Rotatable Transport Guides for Continuous Sheet Path Alignment

Solution Overview

Problem

Conventional automatic teller machines face issues with the bill delivery transport path not being adequately connected to the in-mechanism bill transport path, leading to potential jamming or breaking of bills due to differences in cross-sectional depth when the transport paths are displaced.

Innovation Solution

A sheet transport apparatus with a first pair of parallel transport guides and a second pair of transport guides, where the second pair is rotatable to engage with the first pair, maintaining the same transverse cross-sectional depth, ensuring reliable connection of the transport paths regardless of displacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the in-mechanism transport unit is displaced from immediately above the delivery transport unit toward the mechanism pull-out side or installation side, then the transport paths can accommodate displacement, but the cross-sectional depth of the transport paths becomes inconsistent, causing steps or hollows that lead to bill jamming or breaking

Engineering Contradiction:

Improvetransport path displacement accommodationVSAvoidbill transport reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The movable guides (220, 221) are designed to be rotatable about rotational shafts, allowing them to dynamically adjust their positions and orientations to accommodate displacement of the in-mechanism transport unit. This dynamic adjustment capability enables the delivery transport path to maintain proper alignment and consistent cross-sectional depth with the in-mechanism bill transport path regardless of displacement, thereby preventing bill jamming or breaking while accommodating transport path displacement.

Inventive Principle:

Principle #15Dynamics

2Device complexity

If fixed transport guides are used to form the transport path, then the structure is simple, but the transport path cannot accommodate displacement between the delivery transport unit and in-mechanism transport unit

Engineering Contradiction:

Improvetransport guide structure simplicityVSAvoidtransport path displacement accommodation

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The movable guides (220, 221) are designed to be rotatable about rotational shafts, allowing them to dynamically adjust their positions and orientations to accommodate displacement of the in-mechanism transport unit. This dynamic adjustment capability enables the delivery transport path to maintain proper alignment and consistent cross-sectional depth with the in-mechanism bill transport path regardless of displacement, thereby preventing bill jamming or breaking while accommodating transport path displacement.

Inventive Principle:

Principle #15Dynamics

3Measurement precision

If the front ends of the movable guides are made perpendicular to the mechanism pull-out direction, then the guides are in their reference position, but the transport paths cannot connect when the in-mechanism transport unit is displaced

Engineering Contradiction:

Improveguide positioning precisionVSAvoidtransport path connection under displacement

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The movable guides (220, 221) are designed to be rotatable about rotational shafts, allowing them to dynamically adjust their positions and orientations to accommodate displacement of the in-mechanism transport unit. This dynamic adjustment capability enables the delivery transport path to maintain proper alignment and consistent cross-sectional depth with the in-mechanism bill transport path regardless of displacement, thereby preventing bill jamming or breaking while accommodating transport path displacement.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The movable guides (220, 221) can change their orientation parameters by rotating about the rotational shafts. This parameter change allows the guides to adjust their angles relative to the mechanism pull-out direction, enabling the transport paths to connect properly even when the in-mechanism transport unit is displaced from its reference position, thus maintaining adaptability while preserving precise positioning capability.

AI summary

In a sheet transport apparatus, first transport guides are provided in pair in parallel to, and spaced from, each other to form a first transport path to convey sheets. The transport guides have one ends engageable with the ends of second transport guides, which are provided in pair to be parallel to, and spaced from, each other to form a second transport path. A supporting member rotatably supports the second transport guides in response to the position of the first transport guides. When the ends of the first and second transport guides are brought into engagement with each other with the one ends of the second transport guides inclined against the first transport guides to displace the ends from each other, both transport paths can be connected to each other without changing the transverse cross-sectional depth thereof, thereby preventing a step or hollow from being formed in the connecting section.
