Cardboard Box Stacking Guide Device for High-Speed Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed production of cardboard boxes leads to unstable behavior, causing tilting and damage during stacking, as lightweight large-sized boxes lack sufficient rigidity, resulting in collisions and improper stacking postures.
Innovation Solution
A sheet stacking device with a guide device featuring a first guide part for horizontal support and a second guide part for vertical support, positioned between the ejection unit and hopper unit, to stabilize the cardboard boxes and prevent tilting and damage during high-speed transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If production rate is increased, then productivity is improved, but stability of cardboard box behavior deteriorates causing tilting and damage
Solution Approach 1:
A guide device is introduced as an intermediary component between the ejection unit and the hopper unit. This guide device includes a first guide part that guides the lower surface of the cardboard box in a horizontal direction and a second guide part that guides the rear end of the cardboard box in a vertical direction, preventing tilting and damage during high-speed transport
Solution Approach 2:
The guide device performs preliminary guidance action on the cardboard box immediately after ejection, before the box reaches the hopper unit. By establishing proper orientation and position in advance, the system prevents tilting and collision damage that would occur during high-speed transport to the hopper
2Productivity
If production rate is increased, then productivity is improved, but manufacturing precision of stacking posture deteriorates
Solution Approach 1:
The guide device serves as an intermediary mechanism that ensures precise stacking posture by guiding the cardboard box through specific horizontal and vertical paths. The first guide part ensures horizontal alignment while the second guide part ensures vertical alignment, maintaining precision even at high production rates
Solution Approach 2:
The guidance function is segmented into two independent components: the first guide part for horizontal guidance of the lower surface and the second guide part for vertical guidance of the rear end. This segmentation allows each component to specialize in one direction, improving overall precision while maintaining high speed
3Adaptability or versatility
If lightweight large-sized cardboard boxes are used, then adaptability is improved, but strength deteriorates causing tilting and damage during transport
Solution Approach 1:
The guide device acts as a protective intermediary that compensates for the insufficient rigidity of lightweight large-sized cardboard boxes. By providing external guidance through the first and second guide parts, the system prevents tilting and collision damage that would otherwise occur during high-speed transport
Solution Approach 2:
The guide device applies preliminary anti-action by preventing tilting and collision before they can occur. The horizontal guidance from the first guide part and vertical guidance from the second guide part counteract the natural tendency of lightweight boxes to tilt during high-speed transport

AI summary
Provided are a sheet stacking device, a counter ejector and a box making machine, wherein: a hopper unit stacks sheet-like cardboard boxes; feeding rolls feed a cardboard box to the hopper unit; and a guiding device is disposed between the feeding rolls and the hopper unit and includes a first guide part that extends in a horizontal direction and guides a lower surface of the cardboard box and a second guide part that extends in a vertical direction and guides a rear end of the cardboard box. Due to this configuration, the occurrence of damage to box making sheets in high-speed conveying of the box making sheets can be suppressed and the box making sheets can be appropriately stacked in a prescribed posture.
