Stacking Apparatus Compact Driving Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stacking apparatuses require a large and inefficient driving mechanism to move the stacking stage both vertically and horizontally, leading to a bulky design that complicates the stacking process.
Innovation Solution
A compact driving mechanism that includes a main body part and an arm part, where the arm part extends between the stacking stage and the correction mechanism, allowing independent movement perpendicular to the stacking surface while constraining movement parallel to it, connected via a linear-motion mechanism, enabling precise positioning and reduced size.

Engineering Contradiction Analysis
1Ease of operation
If the stage up-and-down mechanism is configured to cause both the stacking stage and stage correction mechanism to ascend and descend together, then the stacking stage can be moved in the vertical direction, but the driving mechanism becomes large in size due to the increased driving force requirement
Solution Approach 1:
The patent divides the movement control into two independent mechanisms: a stage up-and-down mechanism that moves only the stacking stage vertically, and a stage correction mechanism that moves horizontally independently. This segmentation allows each mechanism to be sized appropriately for its specific function rather than requiring one large mechanism to handle all movements
Solution Approach 2:
The patent separates vertical and horizontal movements into different operational dimensions. The stacking stage moves vertically on a up-and-down mechanism, while the correction mechanism handles horizontal positioning. This dimensional separation enables compact design of individual mechanisms while achieving full two-dimensional positioning capability
2Volume of stationary object
If a compact driving mechanism is used to move only the stacking stage vertically, then the mechanism size is reduced, but the stage correction mechanism must operate independently without vertical movement support
Solution Approach 1:
The stacking stage acts as an intermediary platform that receives vertical movement from the compact up-and-down mechanism, then transfers objects to the correction mechanism for horizontal positioning. This intermediary role allows the system to achieve full positioning capability while keeping each mechanism compact and simple

AI summary
A stacking apparatus includes a stacking stage, a correction mechanism, a driving mechanism, and a linear-motion mechanism. The stacking stage has a stacking surface, on which objects are to be stacked in layers. The correction mechanism moves the stacking stage in a direction parallel to the stacking surface. The driving mechanism moves the stacking stage in a direction perpendicular to the stacking surface. The linear-motion mechanism connects the stacking stage and the correction mechanism, gives freedom of movement in the direction perpendicular to the stacking surface and constrains movement in the direction parallel to the stacking surface. The driving mechanism includes a main body part that does not overlap the stacking stage when viewed in the direction perpendicular to the stacking surface, and an arm part that extends from the main body part and between the stacking stage and the correction mechanism and supports the stacking stage.
