Description
_ 2 - ~9675 The invention relates to a device for determining the position of the cutting head of a drift advarlcing machine or winning machine (Langley shearing machine or heading machine). For determining the position of the cutting head of a drift advancing machine or of a winning machine rota-live to a nominal profile to be cut it is already known to arrange on the frame of the cutting machine radiation receivers which permit to determine in cooperation with signals of a transmitter stationarily arranged in the drift to determine the space coordinates of the longitu-dial axis of the cutting machine. sawed on the space coordinates of the frame of the cutting machine and, no-spectively, the longitudinal axis of the cutting machine determined in this manner, the coordinates of the cutting head were determined with -the aid of additional signals and, above all, by using signals of further means for determining the pivotal position of the cutting arm rota-live to the cutting machine. It is known to pro-vise in such machines indicating devices in which the cutting head was pictured in a spatial or plane represent station relative -to the nominal profile. It is common or all known constructions that the position of the cutting head itself could never be directly determined and-that the actual space coordinates of the cutting head are con-eluded from parallel deviations from the horizontal and the vertical direction, from the inclined position and the inclination relative to the drift axis as well as the roll angle of the machine with considerable technical ~;''~ \
~L2Z9~;75i expenditure. On account of the great number of the no-- squired constructional parts such devices showed a high sustains to failures.
The invention now alms at directly determining with-out determining the position of the chassis of the cutting machine the position of a cutting head and, respectively, the cutting heads of partial cut cutting machines relative to the drift. For solving this task, the device according to the invention is characterized by a receiver oriented relative to the longitudinal axis of the drift and adapted to be mounted within the drift, a transmitter for electron magnetic radiation within the wave range of 1 em to 10 cm arranged on the cutting head and/or on a cutting arm and a telemeter for determining the distance of at least one reference point on the cutting head and/or on the cutting arm from the receiver as well as, preferably, an India acting device for the position of the cutting head relative to a nominal profile to be cut. On account of a trays-miller for electromagnetic radiation being now provided on the cutting head or at a reference point on the cutting arm, the position of the cutting head can exactly be expressed in polar coordinates by one single determination of angle with simultaneous consideration of the distance of said point from the receiver stationarily arranged with-in the drift, and said position expression can be used inn indicating device and, respectively, as the control signal for automatically controlling the drift advancing or winning machine. With consideration of the dust-loaden ~22~67S
atmosphere encountered at the area of the drift face and thus immediately adjacent the cutting head, for this pun-pose there are selected radiations which are scattered -to a lower degree than visible light and have a higher penes treating capacity, i.e. preferably electromagnetic radian lion within the wave range of 1 jut to 10 cm which includes longer waves as visible light. In a particularly ad van-tageous manner, the heat generated during cutting work can be made use of because the bits and the cutting head Jo have a substantially higher temperature than their environ-mint and thus act as transmitters of infrared radiation.
The high temperature difference between the hot bits of the cutting heads and their environment allows the use of relatively insensible receivers, noting that, as a rule, expensive cooling equipment of the receiver can be omitted Preferably, the receiver is designed as a heat picture camera being stationarily arranged within the drift and being oriented relative to the longitudinal axis of the drift by means of, for example, a conducting ray being a laser beam commonly used. Such heat picture cameras have a horizontal line scanning and the video signal thus ox-twined can directly be used in known electronic equipment, be made visible on telescreens and/or supplied to a control equipment. However, the arrangement can also be such, that the receiver is arranged for swiveling movement and can, for the purpose of determining the angle between a line puerilely extending relative to the longitudinal axis of the drift and (the position vector of) the 967~;
reference point of the cutting head, be oriented against at least one reference point, formed of the transmitter, of -the cutting head. Follow-up by means of a servo motor of such a swivel able receiver and its orientation in direction to the transmitter directly supplies a dime-soon figure for the angle to be measured. In combination with the distance measured in a manner known per so, for - example by using infrared radiation, the position of the cutting head can directly be representated.
If only one reference point is used as the transmitter it is to recommend to arrange same close to the axis of rotation of the cutting head because then it becomes possible to determine the exact position of the cutting arm in any of its pivotal positions on account of the known size of a cutting head and the known geometry of the cutting head and in combination with the measured distance. The distance can also be measured between the stationarily arranged receiver and the drift face itself on account of the cutting head engaging the drift face.
Particularly when using a heat picture camera it is of particular advantage if the transmitter designed as a transmitter for infrared radiation is formed of the cutting head itself having attained operating temperature.
In this case, the whole contour of the cutting head is received by the receiver and telemetering could in this case be effected by considering the fact that with a given size of the cutting head its contour gives a greater or, respectively, smaller picture in the heat ~L%29~;7~:;
picture camera with varying distance of the cutting head from the heat picture camera. Any reduction of the size of the cutting head contour as measured with fixed focal length of the heat picture camera corresponds to a greater distance from the heat picture camera.
In an advantageous manner, the indicating device has .
a telescreen on which the relative position of the cutting head and the nominal profile can be represented, noting that the representation of the nominal profile or the represent station of the cutting head can be changed in size independence on the distance of the cutting head from a no-sever for infrared radiation or, respectively, the heat picture camera. In this manner, the scale of the represent station on the telescreen can remain unchanged. This can, in a simple manner be realized if the heat picture camera has a variable-focus lens the focal length ox which is adjustable in dependence on the distance of the cutting head.
The preferred embodiment of the device according to the invention consists in that the heat picture camera is stationarily arranged within the drift in an oriented manner, in that the heat picture is in a manner known per so scanned along lines and in that the video signal thus obtained is supplied to the indicating device and/or to a control ecluipment controlling the movement of the cutting head.
In -the following/the invention is further explained with reverence to embodiments shown in the drawing.
~ZZ9~7~;
In -the drawing Figure 1 shows a schematic representation of the device being arranged within a drift, Figures 2 and 3 show a representation of the geometric conditions applicable for determining the space coordinates, Figure 4 schematically shows the device according to Figure 1 in a side elevation, Figure 5 shows the picture in an indicating device being connected to the arrangement of Figure 1 and Figure 6 schematically shows the circuitry required for evaluating the received signals.
In Figure 1 there is shown a partial cut cutting machine 1 within a drift 2. The cutting arm of this partial cutting machine is designated 3 and has at its end two rotatable supported cutting heads which are rotatable supported for rotation around an axis 5 transversely extending relative to the axis of the cutting arm. A
reference point 6 formed of an infrared transmitter is arranged in closed proximity to said axis 5 on the cutting arm 3. A heat picture camera 8 is stationarily arranged on a consolidating frame 7 and is oriented in suitable manner relative to a drift conducting ray 9 formed of a laser beam. The stationary receiver 8 determines the distance between the receiver 8 and the reference point 6, formed of an infrared transmitter, on the cutting arm.
The Cartesian coordinates of the reference system of the receiver are designated x, y and z, and two angles are measured relative to this coordinate system as - 122967~
is explained by Figures 2 and 3.
In Figure 2, the Cartesian reference system is shown as having its origin point at the measuring point of the heat picture camera 8. The x-y-plane is in a simple manner oriented in parallel relation to the drift conducting ray 9. Based on such an orientation of the reference system of the heat picture camera, the reference point 6 of the cutting arm and, respectively, cutting head is expressed in polar coordinates by the angles I, y and the distance r. Two angles and the distance between the point of origin of the reference system of the heat picture camera 8 and -the reference point on the cutting head or, respectively, cutting arm are measured In an equally well suitable manner also the outer contour, designated 10 in Figure 1, of the cutting heads can as a whole be scanned by means of a heat picture camera. In Figure 3 there are shown the angles to be measured.
Also in Figure 4, the receiver 8 is stationarily arranged and oriented relative to the lGn~itudinal axis of the drift, the receiver being fixedly mounted on a con-solidating frame 7. In this case, the angle is measured relative to the x-y-plane of the reference system of the receiver and is therefore reduced for 90 over the-angle in Figure 3. In an analogous manner, the angle results, in the top plan view not shown, starting from the x-axis of the reference system of the receiver. In place of the distance r between the reference point 6 on the cutting arm and the measuring point of the receiver 8/there can be _ 9 _ ~22~6~
measured the distance a between the receiver 8 and the drift face 11, because this distance is, with a greater distance of the receiver 8 from the reference point 6, only insignificantly different from the distance r.
If now, in place of a certain reference point 6 lo-acted on the cutting arm or on the cutting head and formed of an infrared transmitter, the whole outer contour I of the cutting heads 4 is depicted by the heat picture camera, there can immediately be obtained the representation, shown in Figure 5, on the telescreen from the video signal of the heat picture camera. The screen of the monitors 12 is designated 13 and shows the nominal profile 14 of the drift to be advanced. The pictures of the cutting heads 4 are seen within this nominal profile 14, the tracks ox the no-toting bits being clearly depicted as substantially Yen-tidal extending strokes.
- A circuitry suitable for scanning the video signal of the heat picture camera is schematically shown in Figure 6.
The heat picture camera is designated 8 as is the receiver.
Signals for vertical and horizontal beam deflection are supplied to the camera via conduits 15 and, respectively, 16. The video signal arrives, via a line 17 and a differential element 18 to a comparator 19 and can immedia-tell be supplied to the monitor 12.
For the purpose of automatically controlling the operating movement of the cutting head and, respectively, the cutting arm, this signal can, however, also be supplied to a picture evaluating circuit 20. Thus, separate actuating l 12Z~675 signals for the three space coordinates of the position - of the cutting head can be derived via lines 21.

In -the following/the invention is further explained with reverence to embodiments shown in the drawing.
~ZZ9~7~;
In -the drawing Figure 1 shows a schematic representation of the device being arranged within a drift, Figures 2 and 3 show a representation of the geometric conditions applicable for determining the space coordinates, Figure 4 schematically shows the device according to Figure 1 in a side elevation, Figure 5 shows the picture in an indicating device being connected to the arrangement of Figure 1 and Figure 6 schematically shows the circuitry required for evaluating the received signals.
In Figure 1 there is shown a partial cut cutting machine 1 within a drift 2. The cutting arm of this partial cutting machine is designated 3 and has at its end two rotatable supported cutting heads which are rotatable supported for rotation around an axis 5 transversely extending relative to the axis of the cutting arm. A
reference point 6 formed of an infrared transmitter is arranged in closed proximity to said axis 5 on the cutting arm 3. A heat picture camera 8 is stationarily arranged on a consolidating frame 7 and is oriented in suitable manner relative to a drift conducting ray 9 formed of a laser beam. The stationary receiver 8 determines the distance between the receiver 8 and the reference point 6, formed of an infrared transmitter, on the cutting arm.
The Cartesian coordinates of the reference system of the receiver are designated x, y and z, and two angles are measured relative to this coordinate system as - 122967~
is explained by Figures 2 and 3.
In Figure 2, the Cartesian reference system is shown as having its origin point at the measuring point of the heat picture camera 8. The x-y-plane is in a simple manner oriented in parallel relation to the drift conducting ray 9. Based on such an orientation of the reference system of the heat picture camera, the reference point 6 of the cutting arm and, respectively, cutting head is expressed in polar coordinates by the angles I, y and the distance r. Two angles and the distance between the point of origin of the reference system of the heat picture camera 8 and -the reference point on the cutting head or, respectively, cutting arm are measured In an equally well suitable manner also the outer contour, designated 10 in Figure 1, of the cutting heads can as a whole be scanned by means of a heat picture camera. In Figure 3 there are shown the angles to be measured.
Also in Figure 4, the receiver 8 is stationarily arranged and oriented relative to the lGn~itudinal axis of the drift, the receiver being fixedly mounted on a con-solidating frame 7. In this case, the angle is measured relative to the x-y-plane of the reference system of the receiver and is therefore reduced for 90 over the-angle in Figure 3. In an analogous manner, the angle results, in the top plan view not shown, starting from the x-axis of the reference system of the receiver. In place of the distance r between the reference point 6 on the cutting arm and the measuring point of the receiver 8/there can be _ 9 _ ~22~6~
measured the distance a between the receiver 8 and the drift face 11, because this distance is, with a greater distance of the receiver 8 from the reference point 6, only insignificantly different from the distance r.
If now, in place of a certain reference point 6 lo-acted on the cutting arm or on the cutting head and formed of an infrared transmitter, the whole outer contour I of the cutting heads 4 is depicted by the heat picture camera, there can immediately be obtained the representation, shown in Figure 5, on the telescreen from the video signal of the heat picture camera. The screen of the monitors 12 is designated 13 and shows the nominal profile 14 of the drift to be advanced. The pictures of the cutting heads 4 are seen within this nominal profile 14, the tracks ox the no-toting bits being clearly depicted as substantially Yen-tidal extending strokes.
- A circuitry suitable for scanning the video signal of the heat picture camera is schematically shown in Figure 6.
The heat picture camera is designated 8 as is the receiver.
Signals for vertical and horizontal beam deflection are supplied to the camera via conduits 15 and, respectively, 16. The video signal arrives, via a line 17 and a differential element 18 to a comparator 19 and can immedia-tell be supplied to the monitor 12.
For the purpose of automatically controlling the operating movement of the cutting head and, respectively, the cutting arm, this signal can, however, also be supplied to a picture evaluating circuit 20. Thus, separate actuating l 12Z~675 signals for the three space coordinates of the position - of the cutting head can be derived via lines 21.
