Abstract
Procedure and apparatus for controlling the barking process in a barking drum, which procedure uses measuring devices (13a,13b,14a,14b) placed in conjunction with the barking drum (1) to measure the weight of the drum. The measurement signals obtained from the weight measuring devices are used to calculate the degree of fullness of the drum, and this data is used to control the position of the delivery gate of the drum so as to achieve the desired degree of fullness. Moreover, the degree of barking of the logs is monitored, and the barking degree data is used as a basis for the control of the speed of rotation of the drum.
Claims9
A procedure for controlling a log barking process in a barking drum, said procedure comprising:
- calculating the degree of fullness of the drum by means of measurement signals obtained from at least one weight measuring device operably disposed in conjunction with said barking drum;
- controlling the position of a discharge gate of said drum in response to said calculated degree of fullness so as to achieve a predetermined degree of fullness;
- determining the degree of barking of the logs by monitoring the barking of the logs;
- and
- controlling the speed of rotation of said drum in response to the determined degree of barking.
An apparatus for controlling a barking process in a barking drum, said apparatus comprising:
- a barking drum having a discharge gate;
- means for supporting and rotating said drum;
- at least one device for measuring the weight of said drum, said at least one device disposed in conjunction with said barking drum;
- a computer having input and output means;
- position determining means for determining the position of said discharge gate of said drum;
- means for inputting to said computer measurement signals obtained from said at least one weight measuring device to permit calculation of the degree of fullness;
- means for outputting from said computer a control signal for controlling the position of said discharge gate of said drum;
- and
- means for controlling by said computer the rotation speed of said drum in response to data representing the degree of barking.
