Channel bale press for agricultural harvest crop and device and method for controlling operation of the bale press
First Claim
1. A bale press for agricultural harvest crops, comprising a pressuring channel having at least a portion of one side thereof formed by a pivotal rail section;
- hydraulic means for applying pressure to the rail section;
a plunger displaceable in the pressure channel for compressing a harvest crop therein; and
a control device for controlling operation of the bale press, the control device including a load sensor for sensing loading of the plunger, with the loading representing a first controlled variable, a pressure sensor for sensing pressure in the hydraulic means with the pressure representing a second controlled variable, and means for changing the pressure applied to the rail section upon deviation of at least one of the first and second controlled variables from a respective set value.

Abstract
A bale press for agricultural harvest crops including a pressure channel having at least a portion of one of its sides formed by a pivotal rail section, a hydraulic device for applying pressure to the rail section, a plunger displaceable in the pressure channel for compressing a harvest crop therein, and a control device for controlling operating of the bale press and including a load sensor for sensing loading of the plunger with the loading representing a first controlled variable, a pressure sensor for sensing pressure in the hydraulic device with the pressure representing a second controlled variable, and an operator unit for changing the pressure applied to the rail section upon deviation of at least one of the controlled variables from a predetermined set value.

6. A method of controlling operation of a bale press for agricultural harvest crop including a pressuring channel having at least a portion of one side thereof formed by a pivotal rail section;
- hydraulic means for applying pressure to the rail section;
a plunger displaceable in the pressure channel for compressing a harvest crop therein; and
a control device for controlling operation of the bale press, the method comprising the steps of;sensing loading of the plunger and inputting a loading signal into the control device as a first controlled variable; sensing pressure in the hydraulic means, which apply pressure to the rail section, and inputting a pressure signal into the control device as a second controlled variable; and changing the pressure applied to the rail section upon deviation of at least one of the first and second controlled variables from a respective set value. - View Dependent Claims (7, 8, 9, 10)
