Pallet Station and Nested Cart Layout for Compact Product Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product sorting apparatuses require extensive installation space and carrying-out work space, complicating worker and forklift movement due to parallel arrangement of collecting stations and the need for adjacent carrying-out spaces.
Innovation Solution
A product sorting apparatus with a pallet station that moves up and down, allowing for transfer of products to multiple collecting pallets via movable carts, optimizing space usage and enabling both carts to pass through the pallet station at different heights, thus reducing overall installation and carrying-out space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If collecting stations are arranged in parallel on a plane, then product sorting capability is improved, but installation space requirement increases
Solution Approach 1:
The invention transitions from a two-dimensional parallel arrangement of collecting stations to a three-dimensional configuration by stacking collecting pallets vertically. The pallet station moves up and down between a base position and a raised position, enabling multiple collecting pallets to be arranged in the vertical dimension rather than requiring parallel horizontal arrangement, thus reducing installation space while maintaining sorting capability
Solution Approach 2:
The invention implements nesting by allowing the second cart to pass through the inside of the first cart, and enabling one collecting pallet to be positioned within or alongside another. This nested arrangement allows multiple collecting stations to occupy overlapping spatial volumes, significantly reducing the total installation footprint compared to parallel arrangement
2Ease of operation
If carrying-out work space is secured adjacent to collecting station, then product removal is facilitated, but installation space and worker movement paths are compromised
Solution Approach 1:
The invention relocates the carrying-out work space from a horizontal adjacent position to a vertical position. The pallet station's vertical movement between base and raised positions enables product removal from the front side rather than requiring back side access, facilitating worker and forklift movement paths while eliminating the need for additional horizontal carrying-out space
Solution Approach 2:
The invention inverts the conventional arrangement by placing the carrying-out work space on the front side of the apparatus rather than the back side. This inversion is achieved through the vertical movement mechanism that brings collecting pallets to accessible positions, reversing the traditional spatial relationship and improving both space utilization and operational convenience

AI summary
A product sorting apparatus includes a pallet station supporting a pallet on which a product is placed and moves up and down between a base position and a raised position, a transfer device transferring the product to a first area that is on a first side of the pallet station, a first cart movable between the first area and a second area that is on a second side of the pallet station, and a second cart movable between the first area and the second area and able to pass through the inside of the first cart. Through the inside of the pallet station set at the base position, the first cart is unable to pass and the second cart is able to pass, and through the inside of the pallet station set at the raised position, both the first and second carts are able to pass.
