A controller for a drive motor (60) of a product conveyor belt at a checkout has a phase-start cutting and/or phase-end cutting controller (50) that controls the drive motor (60) in such a manner that the product conveyor belt is accelerated with reduced torque from a non-driven state. A start controller controls the drive motor (60) in such a manner that the drive motor (60) initially drives with a non-reduced torque when accelerating the product conveyor belt from the non-driven state before the phase-start cutting and/or phase-end cutting controller (50) further accelerates the product conveyor belt with reduced torque.

The present invention provides a pot seedling feeding system for a transplanter, including a conveyor unit, a detection sensor, a controller, a seedling separation unit, side plates, and support stands. The conveyor unit includes a step motor, a transmission shaft, a conveyor belt, a tensioning shaft, and bearings. The seedling separation unit includes a seedling separation rod, a reset spring, a guide post, and a support seat. The controller is used to control the step motor which drives the conveyor belt in order to move the pot seedling. When a seedling receiving barrel of the planter rises to a seedling receiving position, the planter is controlled by using a brake cable, the seedling separation rod is then ejected which in turn drives the step motor to carry a pot seedling to move forward. The pot seedling is then dropped in a seedling receiving cup of the planter. In order to improve the quality of pot seedling planting, the seedling separation rod corrects a feeding posture of the pot seedling at the moment when the pot seedling drops. The present invention is about a mechanical seedling feeding system adopting the conveyor unit and the seedling separation unit that move intermittently, where multiple pot seedlings can be placed at a time, so that the operation is simple and fast, labor is saved and the cost is reduced. Stress from missing seedlings and excessive fatigue from repetitive movement are also eliminated from the implementation of this device.

A control apparatus for a conveying system includes: a control module configured to control a power converter coupled to a motor, and a modification module. The modification module is configured to: estimate a size parameter of an item conveyed by the motor, determine if a hold command is received; and if a hold command is received, modify one or more parameters of the control module based on the estimated size parameter of the item to thereby hold a rotor of the motor at a rotor hold position.
