Reversible Rotor Sorting for In-Line Conductor Rod Rejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sorting processes for stator bars in electrodynamic machine production are time-consuming, particularly when retracting chutes to sort out faulty conductor rods, which reduces the cycle rate of conductor rod manufacturing.
Innovation Solution
A sorting machine with a rotor that can rotate in two opposite directions, equipped with receptacles for conductor rods, a feed device, a guide device, and an ejection device, allowing for efficient sorting by rotating the rotor to either transfer or eject conductor rods without interrupting the production cycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a chute is retracted to sort out faulty conductor rods, then faulty rods can be removed from the production process, but the cycle rate at which conductor rods are manufactured must be reduced
Solution Approach 1:
The rotor is designed to rotate dynamically in both clockwise and counterclockwise directions based on the sorting requirements. This dynamic reversibility allows the system to adapt its rotation direction to achieve both transfer and ejection functions without mechanical reconfiguration, resolving the contradiction between sorting capability and production cycle rate
Solution Approach 2:
The rotor serves multiple functions: it can transfer conductor rods to the transfer point, eject faulty rods to the collection device, and do both operations within a single production cycle. This multi-functionality eliminates the need for separate sorting mechanisms that would slow down production
2Productivity
If the rotor rotates to transfer conductor rods to the transfer point, then conductor rods can be passed to subsequent processing, but faulty rods cannot be sorted out
Solution Approach 1:
The rotor's rotation direction is dynamically controlled based on the status of conductor rods. When all rods are good, it rotates to transfer them efficiently. When faulty rods are detected, it reverses direction to eject them, achieving both high transfer efficiency and reliable sorting capability

AI summary
The invention relates to a sorting machine (10) for extension ladders (14) comprising: - a rotor (42) rotatable in two opposite directions about a rotational axis (40) with at least two circumferentially offset receptacles (38) for each extension ladder (14); - a feeding device (32), in particular a gripper (34), for moving one extension ladder (14) to a receptacle (38) of the rotor (42) located at a receiving point (36); - a guiding device (66) for guiding the extension ladder (14) picked up at the receiving point (36) by one of the receptacles (38) from the receiving point (36) to a transfer point (52) when the rotor (42) rotates in a first direction (48); - a discharge device (78) for discharging the extension ladder picked up at the receiving point (36) by one of the receptacles (38) when the rotor (42) rotates in a second direction (50). (14) can be seen from the recording (38).The sorting machine enables the accelerated sorting of pole ladders that are not to be passed on to a subsequent process.
