Palletizer Infeed Orientation and Spacing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Palletizing systems face inefficiencies due to the frequent misorientation and improper spacing of boxes, leading to defective layers and operational slowdowns, posing safety concerns and reducing throughput.
Innovation Solution
The infeed system, comprising a metering belt, case turner, and pusher bar sections, uses computerized processors and electro-optical sensors to ensure boxes are correctly oriented and spaced according to a predefined build menu, automatically correcting out-of-bounds situations to prevent defective layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If boxes are delivered to the palletizer without orientation and spacing control, then the infeed system is simple and fast, but boxes are frequently misoriented and improperly spaced causing defective layers and operational slowdowns
Solution Approach 1:
The infeed system performs preliminary orientation and spacing adjustment of boxes before they reach the palletizer. The apparatus includes orientation adjustment mechanisms that correct box orientation and spacing in advance, preventing defective layers and operational slowdowns downstream.
Solution Approach 2:
The system incorporates sensors and control mechanisms that monitor box orientation and spacing in real-time, providing feedback to adjust the infeed system parameters dynamically. This ensures boxes are consistently delivered in the correct orientation and spacing.
2Reliability
If operator intervention is used to correct misoriented boxes, then orientation accuracy can be maintained, but productivity decreases due to shutdowns and safety concerns
Solution Approach 1:
The infeed system is designed to automatically detect and correct misoriented boxes without requiring operator intervention. The apparatus includes self-adjusting mechanisms that maintain orientation accuracy while keeping the palletizer running continuously, eliminating shutdowns and improving safety.
3Manufacturing precision
If the infeed system includes orientation adjustment equipment, then box orientation and spacing are improved, but the system speed and throughput are reduced
Solution Approach 1:
The infeed system uses dynamically adjustable orientation and spacing mechanisms that can quickly adapt to different box configurations. The system adjusts parameters in real-time based on detected box positions, maintaining high throughput while ensuring precise orientation and spacing.

AI summary
An infeed apparatus includes an item manipulator that orients items such as cases in a desired orientation as determined by a build menu, and a row build apparatus that is synchronized with the manipulator to space items pursuant to the build menu. The manipulator uses a pusher to push items across a friction belt to thereby orient the items, and includes sensors for determining when an item is in an incorrect orientation. The row build receives items from the pusher and is selectively advanced to locate items in a desired relative orientation so that rows of items are built correctly.
