Definitions
- Galette for guiding and promoting a thread
- the invention relates to a godet according to the preamble of the claim
- the invention is therefore based on the object, the causes of the weakening of the godet casing and the occurrence of heated godets eliminate unbalance.
- the object is achieved in a generic godet by the characterizing part of claim 1.
- this measure eliminates the time-consuming processing of the godet casing required in the prior art. It is also important, however, that the temperature sensors of a godet that adapt to the curvature of the godet jacket and are in contact with one another without space, have the same distance from the axis of rotation in all temperature measurement zones, which is why the temperature gradient to the thread overflow surface of the godet jacket in all temperature sensors of a godet is or can be the same.
- the attachment to the inner godet jacket should be full-surface. An adhesive or clamp connection has proven to be favorable for this.
- Heated godets are usually divided into several heating zones over their length, especially in the case of large lengths.
- the temperature sensor can expediently be divided in the longitudinal direction into a plurality of measuring regions of the same type, which may also be interconnected, each having associated measuring value taps which are assigned to the heating zones of the godet.
- the measured value taps are expediently combined at one end of the strip and are connected to the measuring ranges assigned to them by conductor tracks. It is also possible to divide the band-shaped temperature sensor extending over the length of the godet jacket into a number of independent temperature sensors with the same number of heating zones in the godet jacket, each with its own measuring lines.
- the measured value taps of the temperature sensor or sensors which circulate with the godet jacket, are arranged circumferentially distributed on a circle. They are assigned, for example, a scanner held in position at the front end of a hollow, stationary carrier, which scanner in turn is equipped with tap contacts.
- the carrier extends from the bearing side of the godet through a central hole in the godet shaft to the front end of the godet and carries the measuring lines which connect the tapping contacts to an electronic evaluation device.
- Such mechanical scanning is essentially used for low speeds.
- a contactless transmission of the measured values determined on the godet casing to the evaluation device is provided, as is the case, for example, in principle from the
- FIG. 1 shows the longitudinal section through a godet according to the invention with a common multiple temperature sensor.
- Fig. 2 shows the basic drawing of a band-shaped temperature sensor.
- Fig. 3 shows the longitudinal section through a further embodiment of the
- FIG. 3A shows an enlarged detail from FIG. 3; 4 shows the circuit diagram of a godet heater according to the invention. tongue.
- the godet casing 3 is connected in a conventional manner to the godet shaft 6 in a rotationally fixed manner via the godet end wall 4.
- a tubular holder 11 attached to the machine frame 1 extends close to the godet end wall 4, but without touching it.
- Annular heating elements 7-10 for example induction coils, are applied to the holder 11 and supplied with current in a manner not shown.
- an axially parallel temperature sensor 12 is fastened, preferably glued flat. It is common to all heaters 7-10 and divided into corresponding sections (see Fig. 2).
- the temperature sensor 12 is guided from the outside of the end wall 4 through one of the slit-shaped openings 5 provided in the end wall 4, for example into the interior of the godet casing.
- the part 13 of the temperature sensor 12 carrying the tapping contacts is guided on the outside of the end wall 4 to the center thereof. Its structure and function are explained below.
- FIG. 2 shows an example of an embodiment of the temperature sensor 12 used according to the invention. It is divided into individual measuring sections - in adaptation to the galette shown in FIG. 1 and having four heating zones 7 to 10 and four measuring sections 14 to 17 - which are connected via conductor tracks 20 are connected to the tapping contacts 18 arranged on the contact disk 13.
- the entire switching arrangement is provided on both sides with a cover, for example covered with a film 19, which only leaves the tap contacts 18 free.
- the cover is preferably made of polyimide; for example, it can also consist of a Fiberglass silicone rubber supporting foil nid 'with a top layer of Po, embedded in a ceramic layer silicate fiber or (a) another material or combination of materials, provided the latter to the process-related Galettentemperaturen, for example 25O ° C to 350 ° C is heat-resistant.
- the contact disk 13 is placed in such a way that when the godet casing 3 rotates, all of the tapping contacts 18 run in a circle concentric with the godet shaft 6.
- the godet shaft 6 is designed as a hollow shaft and is provided with a coaxial longitudinal bore which continues in the fastening screw (not specified in more detail) and opens into the head thereof.
- the surface of the scanner 21 facing the contact disk 13 is equipped with at least one, preferably with two or more scanning elements 22, which are individually connected via measuring lines 24 to an evaluation unit (not shown).
- FIGS. 3 and 3A show a further embodiment of the godet (2) according to the invention with a temperature sensor 12 which is divided into individual measuring sections which are assigned to the individual heaters 7-10.
- Their structure is essentially the same as that of the above-described embodiment shown in FIG. 1, but the forwarding of the signals picked up by the temperature sensor 12 and its measuring sections 14-17 is solved differently.
- the embodiment according to FIG. 1 with its part 13 carrying the tapping contacts 18, it leads to the godet shaft 6 temperature sensor
- the measuring line bundle 24 ends here at the rear shaft end 6A (see in particular Fig. 3A) in a disk 13A, which is equipped with tapping contacts 22 and is fixed on the end face of the shaft, and which is opposite a scanner 27A connected to the machine frame 1 as part of a measured value converter explained below 27 is arranged.
- Protective tube 23, measuring line bundle 24 and the contact disks 13A, 28 run together with the godet casing 3 and the end-side godet cover 29, while the holder 11 projecting out of the machine stand 1 and the heaters 7-10 attached thereon are stationary. Drive and *. Storage of the godet shaft 6 are carried out in a known manner and are therefore not shown in detail.
- the program to be driven is selected by appropriate programming of a control center 31.
- the induction coils 30 are supplied with a base load by the high-frequency supplies 32, 33 in accordance with this program.
- the temperature sensors 12 or the individual measuring sections of a multiple temperature sensor 12 generate signals corresponding to the godet temperatures which are transmitted via the line Bundle 24 get into a transducer 27, where they are converted into digital signals and from there via a transducer 35 to the temperature control 34.
- the actual values are compared with the target values specified by the central unit 31 and the corresponding correction signals are generated.
- the HF supply units 32, 33 are equipped with the values from the actual value setpoint. acted upon compared control signals obtained and the power supply to the induction coils 30 modified accordingly.
- the invention is not limited to the use of a temperature sensor 12 as shown in FIG. 2; this represents only one example.
- the embodiment of the measured value transmission from the rotating part of the godet to the stationary part of the machine frame described and shown in the drawing should in no way limit the invention. Rather, other solutions are also possible which are familiar to the person skilled in the art who deals with such measurement problems or are described in the specialist literature. the.
- measuring unit 14 measuring section, measuring unit
- measuring unit 16 measuring section
- measuring unit 17 measuring section, measuring unit
