AI Technical Summary
In existing chain-recirculation sorting systems, when the placement mechanism returns to the receiving state, the locking hook may open incorrectly due to inertia or vibration, and cannot close again. This causes the placement mechanism to collide with and damage the equipment components, and prevents the timely acceptance of new sorted items.
Design an operational safety device for a chain-loop sorting system. The device uses an internal limit track in conjunction with the transmission chain structure, and through a guide ramp and a reset structure, ensures that the material tray of the placement mechanism does not collide with equipment components during the reset process, and maintains reliable closure of the locking hook.
It achieves reliable reset of the placement mechanism, avoids impact damage to equipment components, and ensures continuous operation and high sorting efficiency of the sorting system.
