Definitions
- the invention relates to a device for measuring the temperature of a roll Heating godet according to the preamble of the independent claim.
- the temperature of the roll of a heating godet is structured as follows.
- a sensor is attached to a probe carrier and protrudes into an air gap in the role, the rotating Part of the heating godet.
- a measuring element is arranged in the area of the tip of the sensor.
- the air gap is between the short-circuit ring, the actual heat generator and the roller jacket, which forms the looping area with its outer surface.
- the short-circuit ring is an optimal heat conductor, which the heat generated in it well conducts and releases well to the surrounding roller jacket. Since one is as accurate as possible Measuring the temperature of the roll, more precisely the roll jacket required, the air gap is sufficient from the side to almost in the middle of the wrapping area of the roll cover.
- the invention has for its object to provide a measuring device which this Accuracy significantly improved.
- the goal is that the new device can also be used for modern textile filaments, which are transported by means of heating godets, pre-stretched and for special procedures are prepared. These have to be accurate Own temperatures are brought.
- the roller 2 consists of an inner concentric short-circuit ring 21 and an outer concentric roller jacket 22. Take over the textile filaments the temperature only from the surface in the wrapping area 23 on the roller jacket 22 and therefore have at least approximately this temperature. But because in the material of the Roll 2 a heat flow from the heat-generating short-circuit ring 21 towards removed surface of the roll shell 22 takes place and also from the textile filament Thermal energy is absorbed, the temperature in the area of the air gap 3 after the prior art ( Figure 1) not the temperature at the surface in Wrapping area 23 correspond.
- the roller shell 22 is changed in its geometry such that the mounting side forth a cylindrical air gap 3 can be arranged so that it three sides of the same material of the roll shell 22 is encompassed. He is thus approximately the same radial distance from the shaft axis as the Wrapping area 23 of the roller jacket 22.
- the sensor 14 protrudes from the stationary one Part 11 of the heating godet laterally in this air gap 3. In the area of its free end is one Measuring probe 15 arranged.
- FIG. 2 shows the new device for measuring the temperature of a heating godet according to the present invention shown in the corresponding section.
- the Roller jacket 22 completely covers the short-circuit ring 21 here. This means that the Air gap 3, into which the sensor 14 protrudes, completely of the same material is embraced.
- the heat transfer (shown with small arrows) from the short-circuit ring 22 into the material of the roller jacket 22 has shorter paths and the contact area between both are bigger. The heat transfer is therefore better in and of itself. So that Sensor 14, the temperature of the surface of the roller jacket 22 im as accurate as possible Wrapping area 23 can capture appropriate conditions must be created become. This is done by ending the role itself, that is against the fixed mounting side of the heating godet is expanded.
- the role therefore instructs this point has a diameter which is larger than that in the Wrapping area 23. There is an almost even heat flow in the material instead of.
- the air gap 3 is now in this extension. It has a cylindrical shape on which is covered on three sides by the same material of the roll shell 22. The The geometric center of the cross section of the air gap 3 is approximately the same Height as the surface of the wrapping area 23. Both have approximately the same radius from the shaft axis of the heating godet.
- the sensor 14 is now arranged in such a way that its measuring probe 15 really approximates that Temperature detected on the surface of the wrapping area 23. This is through the described position and by the thermal uniformity of the air gap given surrounding material. Since the same material in the expanded area 24 of the Roller jacket 22 also limits the air gap on the outside, always finds a similar one Heat transport takes place in this outer extension. Here is due to the enlarged exterior Surface continuously emits a little more heat into the ambient air than it does in Looping area happens. This greater heat can now be released Enlargement of the outer surface in this area should be optimized so that the additional dissipation of heat to the ambient air approximately that of the filament amount of heat absorbed corresponds. This measure can Surface temperature of the roll shell 22 in the wrap area 23 even more precisely be measured. The actual temperature in the filament wrapping around the heating godet is better approximated. Due to the now possible regulation of the heating output, the temperature can be influenced more precisely in the filament, which ultimately also the desired end goal of Measurement is.
- the sensor 15 comprises a rod-shaped element which is fastened to a carrier 13 is.
- the carrier 13 is part of the fixed part 11 of the heating godet and thus with this together stationary against a mounting plate.
- the carrier can act as a heat sink be designed.
- the measuring accuracy of the measuring probe 15 is further increased by heat.
- the sensor 14 itself as a cylindrical part, which extends over the entire circumference. This cylindrical part now protrudes from outside into the likewise cylindrical air gap, of course without contact.
- One or more measuring probes 15 are regularly distributed over its entire circumference arranged. Partial separation slots 17 in can be formed between the individual measuring probes 15 Sensor 14 are arranged. By averaging the signals of the measuring probes 15 the measuring accuracy can be further increased.
- the new device for measuring the temperature of the roll jacket 22 of a heating godet now enables a significantly faster readjustment of the heating output, so that a Desired constancy of the temperature in the wrapping area 23 can be achieved. This is a decisive factor in obtaining better filaments or yarn qualities.
