Solution Overview

Problem

Conventional apparatuses for aligning and positioning triangular-shaped food dough pieces, such as croissant dough, face challenges in achieving high dimensional accuracy and speed due to pin vibration and misalignment issues with pantograph type mechanisms, leading to poor formation of dough pieces.

Innovation Solution

An apparatus comprising an upstream and downstream conveyor system with a separating apparatus and a laying-out and rotating apparatus, equipped with a detecting device using optical or image sensors to accurately position and rotate dough pieces, and a shutter apparatus for aligning bases, ensuring precise alignment and rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a pantograph type mechanism is used to expand and contract the laying-out apparatus, then the pieces of food dough can be separated and laid out in the perpendicular direction, but the pins of the laying-out apparatus vibrate largely in a horizontal plane, making it difficult to position the pins stably and with high accuracy

Engineering Contradiction:
Improvelayout speedVSAvoidpin positioning accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

A guide plate is introduced as an intermediary component between the pantograph mechanism and the pins. The guide plate has through holes that guide the pins, constraining their movement to a vertical path and preventing horizontal vibration. This mediator absorbs the vibratory effects of the pantograph mechanism while maintaining precise pin positioning for accurate dough piece placement.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the center of the pin of the laying-out apparatus does not correspond to the center line of the triangular-shaped food dough, then the apparatus can operate, but the pieces of food dough are located off the position where they should be located, causing poor formation

Engineering Contradiction:
Improveoperational flexibilityVSAvoiddough piece positioning accuracy
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

A detecting device (optical sensor or image sensor) is positioned to detect the center line of each triangular-shaped dough piece as it moves along the conveyer. This detection information is fed back to the control system, which adjusts the lateral position of the pins to correspond with the detected center lines. This feedback mechanism ensures accurate positioning regardless of variations in dough piece placement or orientation.

Inventive Principle:
Principle #23Feedback

3Productivity

If the downstream conveyer moves faster than the upstream conveyer to achieve high speed laying out, then productivity increases, but the pieces of food dough move by slipping on the conveyer surface, requiring complex separating and laying-out mechanisms to maintain precision

Engineering Contradiction:
Improveconveyer speedVSAvoidseparating and laying-out mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The guide plate serves as a mediator that simplifies the separating and laying-out mechanisms. By providing fixed lateral guidance through its through holes, the guide plate eliminates the need for complex lateral positioning mechanisms. The pins simply move vertically through the guide plate holes, and the controlled slipping on the conveyer surface is sufficient for operation, reducing overall system complexity while maintaining precision.

Inventive Principle:
Principle #24Intermediary (Mediator)
