Systems and methods are disclosed for a shuttle sortation system having linear actuators for unloading items from shuttles and deposing the items into totes. For example, an item shuttle may transport items in an item holder which may contain an item and that is removable from a base of the item shuttle. The item holder may be constrained from moving with respect to the base and a depositing area may unlock the item holder from the base, permitting the item holder to separate from the base. An upper linear actuator may engage the item holder and may move the item over a tote receiving the area having a tote. The item holder may not have a bottom portion, such that once the item holder is separated from the based, the item is free to fall through to the tote below.

Systems and methods are disclosed for rapid braking of shuttles powered by electromagnets. An example system may include a first brake coupled to a track at a first location, the first brake including a first housing, a first retractable pin, a second retractable pin, a first actuator configured to actuate one or more of the first retractable pin and the second retractable pin from a retracted position to an extended position, a second actuator configured to actuate one or more of the first retractable pin and the second retractable pin from the extended position to the retracted position, and a first controller configured to control operation of the first brake.

Systems and methods are disclosed for seamless disengagement of shuttles powered by electromagnets. An example system may include a frame coupled to a track, a first conveyor disposed along the first side of the track, a second conveyor disposed along the second side of the track, and an actuator configured to drive the first conveyor and the second conveyor, where the first conveyor and the second conveyor are configured to engage a first bar disposed on a lower surface of the shuttle. The system may be configured to (i) move the shuttle from a first location along the track to a second location along the track, and (ii) pause movement of the shuttle between the first location and the second location.

An automated trimming system is provided that includes a vision system identifying the number of rings positioned within a coil and sheared positions where the rings need to be cut. One or more trimming mechanisms receive the sheared positions and proceed to cut the rings at the sheared positions. A hook arrangement interfaces with the coil for transferring the coil to a trimming area. Moreover, an automated trimming system is provided that includes a coil having a plurality of rings. One or more trimming mechanisms select a number of rings from the coil and proceed to form a sample of desired length, by cutting a portion of the rings. A receiver unit receives the sample from the one or more trimming mechanisms to evaluate the quality of the sample.
