Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for spreading containers apart are limited in application and cost-effective production, primarily designed for cylindrical objects with complex designs and high production costs due to specialized belts and mechanisms.
Innovation Solution
A device featuring a single-track feed conveyor with lateral guide railings and a multi-track discharge conveyor with endless flat-top chains, driven by synchronized motors, and a transfer station with a pivoting sectional beam and pushrod mechanism to adjust and separate upright containers of various diameters, allowing for efficient spreading without altering transport velocity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If serpentine belts with special cams are used to spread containers, then containers can be offset laterally, but production costs become high and application area is limited to cylindrical shapes
Solution Approach 1:
The transport channel with flat belts is designed to handle multiple container types (cylindrical, rectangular, irregular shapes) through a single universal mechanism. The flat-top chains and guide railings create a versatile system that can accommodate various container geometries without requiring specialized components for each shape type.
Solution Approach 2:
The invention replaces expensive serpentine belts and specially shaped cams with simpler, cheaper flat belts and guide railings. The flat-top chains and basic mechanical components are more economical to manufacture and replace, reducing overall production costs while maintaining functionality.
2Productivity
If oppositely driven belts with variable speed are used to increase back-pressure, then containers can be spread apart, but device complexity increases significantly
Solution Approach 1:
The invention extracts the speed control mechanism from the transport belts themselves and replaces it with a passive mechanical spreading system using guide railings and a single pusher element. This removes the complexity of variable speed drives while maintaining spreading functionality through geometric constraints and single-point contact.
Solution Approach 2:
A single pusher element acts as an intermediary between the transport channel and containers, providing the spreading force without requiring complex multi-speed belt systems. The pusher, guided by simple railings, mediates the interaction between containers and achieves separation through a straightforward mechanical action.
3Device complexity
If single-track feed conveyor with guide railings is used, then containers can be guided through transfer station, but spreading capability is limited without complex mechanisms
Solution Approach 1:
The invention introduces lateral spreading capability through guide railings that constrain containers in the horizontal plane, adding a dimensional aspect to the spreading process. The multi-track discharge conveyor arranged side-by-side provides lateral separation, achieving spreading through spatial arrangement rather than complex mechanical manipulation.
Solution Approach 2:
Containers are preliminarily guided and positioned by the guide railings in the feed conveyor before reaching the transfer station. This preliminary alignment and constraint setup enables efficient spreading at the discharge end without requiring complex mechanisms during the actual separation process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the cost-effective spreading of a wide range of container shapes at high output rates, maintaining transport velocity and ensuring containers are separated and aligned correctly for further processing, with adjustable conveyor belts accommodating different bottle sizes.
Implementation Method 1
These surfaces form a single-file transport channel K for the bottles F adjoining the feed conveyor 2. By means of the threaded spindles 20, the retaining brackets 21 and thus the conveyor belts 5, 6 can be adjusted symmetrically to the center of the feed conveyor 2 and adapted to bottles of various diameters. The conveyor belts 5, 6 are adjusted so that they rest with slight pressure against the bottles F and thus carry them along by frictional contact.

AI summary
Device for spreading apart a single-file stream of upright containers, with a single-track feed conveyor, a multi-track discharge conveyor, and a transfer station, which comprises two oppositely driven belts, which form a transport channel for the containers and which can be driven at essentially the same transport velocity as the feed conveyor, where the transport channel formed by the belts is straight and releases the containers with excess velocity onto the discharge conveyor, which can be driven at a slower transport velocity than the feed conveyor.
