Baler with start-up control system

摘要

A baler has a flywheel, a plunger connected to the flywheel via a crank, an auxiliary motor for rotating the flywheel in a reverse direction and a start-up control system comprising a sensor for providing a signal indicative for the position of the crank and a control unit for controlling the auxiliary motor for rotating the flywheel in reverse direction to a predetermined launch position for enabling the flywheel to gain sufficient kinetic energy before the first plunger impact, at the next start-up.

主权项

1. A baler comprising:
a shaft, and a flywheel connected to the shaft and adapted for rotating in a forward direction for producing bales; a plunger connected to the flywheel via a crank, the plunger adapted for performing a reciprocal movement between a near position in which crop material may be added in a bale chamber, and a distal position in which the crop material is compressed in the bale chamber; an auxiliary motor connectable to the flywheel for starting up rotation of the flywheel; a start-up control system, comprising: at least one sensor indicative for a position of the crank and a control unit connected to the at least one sensor and adapted for controlling the auxiliary motor for rotating the flywheel in a reverse direction to a predetermined launch position.
