Abstract
In the processing of a band of fiber material at a plurality of processing locations in a textile machine which operates while periodically being unattended and receives the fiber material band to be processed from supply containers, a sufficient supply of fiber material to the machine is assured by automatically monitoring the quantity of fiber material in each container, and producing an output signal when the monitoring indicates that the quantity of fiber material in a container has reached a lower limit value.
Claims16
In the processing of a band of fiber material at a plurality of processing locations in a textile machine which operates while periodically being unattended and receives the fiber material band to be processed from supply containers, the improvement comprising continuously determining the fill level of the fiber material in each of the supply containers by means of an automatic monitoring device, and producing an output signal when the monitoring device indicates that the fill level of the fiber material in the container has reached a predetermined lower limit value which is at least equal to the fill level required for the subsequent attendance free period of operation to thereby permit maintenance of a sufficient supply of fiber material to the machine during said period of operation.
In a textile machine which operates while periodically being unattached for processing a band of textile material and including at least one supply container filled with the band of textile material and means conducting the material from the container for processing, the improvement comprising means for continuously determining the extent to which said supply container is filled with fiber material, said means including automatic monitoring means connected for monitoring the quantity of fiber material in said container, and indicator means connected to said monitoring means for producing an output signal when the monitoring performed by said monitoring means indicates that the quantity of fiber material in said container has reached a predetermined lower limit value;
- said value being at least equal to the fill level required for the subsequent attendance free period of operation.
In a textile machine which operates while periodically being unattended for processing a band of textile material and including at least one supply container filled with the band of textile material and means conducting the material from the container for processing, the improvement comprising means for continuously determining the extent to which said supply container is filled with fiber material, said means including automatic monitoring means comprising a weighing unit having a vertically movable weighing platform supporting said supply container, said monitoring means connected for monitoring the quantity of fiber material in said container, and indicator means comprising a variable height control switch connected to said monitoring means to be actuated by a magnet fastened to said weighing platform for producing an output signal when the monitoring performed by said monitoring means indicates that the quantity of fiber material in said container has reached a predetermined lower limit value.
In a textile machine which operates while periodically being unattended for processing a band of textile material and including at least one supply container filled with the band of textile material and means conducting the material from the container for processing, the improvement comprising means for continuously determining the extent to which said supply container is filled with fiber material, said means including automatic monitoring means comprising an ultrasonic transmitting receiving unit connected for monitoring the quantity of fiber material in said container, and indicator means connected to said monitoring means for producing an output signal when the monitoring performed by said monitoring means indicates that the quantity of fiber material in said container has reached a predetermined lower limit value.
In a textile machine which operates while periodically being unattended for processing a band of textile material and including at least one supply container filled with the band of textile material and means conducting the material from the container for processing, the improvement comprising means for continuously determining the extent to which said supply container is filled with fiber material, said means including automatic monitoring means comprising an inductive sensor connected for monitoring the quantity of fiber material in said container, and indicator means connected to said monitoring means for producing an output signal when the monitoring performed by said monitoring means indicates that the quantity of fiber material in said container has reached a predetermined lower limit value.
In a textile machine which operates while periodically being unattended for processing a band of textile material and including at least one supply container filled with the band of textile material and means conducting the material from the container for processing, the improvement comprising means for continuously determining the extent to which said supply container is filled with fiber material, said means including automatic monitoring means comprising a pressure measuring box which operates according to the magnetic-elastic principle which is disposed in the intake area of said supply container and is connected for monitoring the quantity of fiber material in said container, and indicator means connected to said monitoring means for producing an output signal when the monitoring means indicates that the quantity of fiber material in said container has reached a predetermined lower limit value.
In a textile machine which operates while periodically being unattended for processing a band of textile material and including at least one supply container filled with the band of textile material and means conducting the material from the container for processing, the improvement comprising means for continuously determining the extent to which said supply container is filled with fiber material, said means including automatic monitoring means connected for monitoring the quantity of fiber material in said container, and indicator means connected to said monitoring means for producing an output signal when the monitoring performed by said monitoring means indicates that the quantity of fiber material in said container has reached a predetermined lower limit value;
- and wherein said monitoring means comprises a transmitting unit disposed to one side of said container for emitting radioactive radiation toward the interior of said container, a radioactive radiation receiver disposed to the side of said container opposite to said one side for receiving radiation which has been emitted by said transmitting unit and passed through the fiber material in said container and for producing a monitoring signal proportional to the intensity of the radiation it receives, which is inversely proportional to the quantity of fiber material in said container, and a comparison unit connected between said receiver and said indicator means for receiving the monitoring signal from said receiver and causing said indicator means to produce its said output signal.
