Definitions

  • the present invention relates to a device and to a method for determining a contact state of a compactor roller with a base to be compacted representing a rump.

  • information is provided which, for example, based on a complete revolution of the compressor roller, in association with a detection circumferential region, represents that portion in which a detection peripheral region is in contact with the substrate to be compacted.
  • This proportion ie the greater the distance between contact start and contact end, the greater the extent of contact between the compactor roller and the substrate to be compacted, which indicates that the compactor roller penetrates comparatively deep into the material of the substrate to be compacted and this Therefore, it is relatively compact.
  • the compactor roller penetrates less deeply into the building material of the substrate to be compacted, which means that, relative to an entire revolution or the entire circumference of the compactor roller, that portion in which contact with the substrate to be compacted decreases.
  • the contact patch to be determined with the device according to the invention therefore permits a conclusion as to the degree of compaction of the substrate to be compacted and can thus be used to define further compaction or machining measures on the substrate to be compacted.
  • a plurality of detection peripheral areas each having at least one contact sensor distributed around the roller axis of the compressor preferably in the same axial area of the compactor roller is provided. It is particularly advantageous if the detection peripheral areas are arranged with substantially the same circumferential distance, preferably about 90 ° to each other. By a uniform spacing of the detection perimeter areas, a periodic detection pattern of the various detection perimeter areas can be provided with a defined time offset and used for the evaluation.
  • sensors which, with a comparatively simple structure, reliably permit a conclusion as to whether or not the region in which a respective contact sensor is positioned, that is to say a respective detection peripheral region, is in contact with the substrate to be compacted.

  • that duration during which a respective detection peripheral area moves in contact with the substrate to be compacted is set in relation to the time period in which such a contact does not exist or at the time of one complete revolution of the compactor roller.
  • the contact patch is composed of a first contact patch part between the start of contact of at least one detection peripheral area with the ground to be compacted and a contact reference position and a second contact patch part between the contact reference position and the contact end.
  • this contact reference position may represent a deepest positioning of the detection peripheral area in the course of the circumferential movement of a detection peripheral area with respect to a perpendicularly orthogonal to the substrate to be compacted, where the first footprint is a bow-sided part of the barrier and the second pad is a rear-side part of the pad.
  • a contact reference position may comprise a contact region located substantially directly below the axis of rotation of the compactor roller in the vertical direction.
  • the preceding part in the direction of movement is considered to be bow-side and will generally have a greater extension than the trailing rear-side part due to the presence of the above-mentioned bow wave.
  • the contact reference position is determined based on at least one Wheelposition istsreferenz.
  • a rotational positioning reference may be generated, for example, by interaction of at least one detection perimeter area with a rotational positioning reference area.
  • a first detection coverage area essentially generates a rotational positioning reference by interaction with a rotational positioning reference area when a second detection peripheral area is in the contact reference position.
  • the contact patch which can be determined by the method according to the invention, can represent a peripheral region of the compactor roller that is in contact with the substrate to be compacted.

  • a rotational positioning reference region 30 formed, for example, as a reference wheel 28 abutting the outer circumference of the roll mantle 13 can be used in the manner described below to generate a rotational positioning reference for the compactor roll 12 in cooperation with the contact sensors 1, 2, 3, 4. Whenever one of these contact sensors 1, 2, 3, 4 moves past the rotation positioning reference area 30, a change indicating this movement will occur in the contact signal S1, S2, S3, S4 of the respective contact sensor 1, 2, 3, 4, which indicates that at this time, this contact sensor generating a respective contact signal has moved past the rotation positioning reference area 30. It should be noted that this rotational positioning reference region 30 need not necessarily be formed as a reference wheel.

  • This contact reference position K divides the between the two lines A and E.
  • the Fig. 2 shows the time course of the generated by the contact sensors 1, 2, 3, 4 contact signals S1, S2, S3, S4.
  • These contact signals S1, S2, S3, S4 are only examples of a variety of waveforms, which respectively indicate whether one of the detection scope in question 18, 20, 22, 24 in contact with the substrate 14 to be compacted or, for example, past the rotational positioning reference 30 moved or not.

  • the signal level of the contact signal S3 drops significantly.
  • the point in time at which the contact signal S3 assumes its minimum value can be selected as the time for the contact to occur.
  • the detection scope 22 reaches the area or to the line E, so that at the time t E of the detection peripheral area 22 out of contact with the substrate to be compacted 14 occurs and consequently the signal level increases again.
  • the timing of the rise of the signal level may be taken as the timing of the termination of the contact between the detection scope 22 and the ground 14 to be compacted. This means that between the two times t A and t E, the detection perimeter area 22 was in contact with the material to be compacted.

  • three detection perimeter areas could be provided with an angular spacing of 120 °. It would also be possible to work with, for example, only two detection perimeter ranges which have an arbitrary circumferential distance from each other. It should be noted in each case that, advantageously, when one of the detection perimeter areas is in the contact reference position K, another detection perimeter area cooperates with the rotational positioning reference area 30 to generate the rotational positioning reference. Also, a single detection perimeter area could result in the desired result by interacting with a rotational positioning reference area.
  • the rotational positioning reference area 30 about the compressor roller rotational axis D can be shifted forwards or backwards by 90 ° so that, for example, the contact signal S4 or S2 of the contact sensor 4 or of the contact sensor 2 could be used in association with the detection circumference area 22 or the contact sensor 3.
  • the Fig. 3 illustrates a simplified example that, or as in the case of a represented by the angle ⁇ Aufstands conducting a riot width b can be determined.

That's how it shows Fig. 5 a known as a pipe sensor acoustic contact sensor 1. this is fed via an air line 30 with air L, which generates a whistling sound in the contact sensor 1. This in turn can be picked up by a microphone 32.
  • the contact sensor 1 is open to the environment via an opening 34 in the roll shell 14, so that depending on whether the opening 34 is covered or not, different frequencies of the sound generated in the contact sensor 1 will adjust, whereby a passing of the detection scope 18, for example on Rotational positioning reference region 30 or can be detected on the substrate 14 to be compacted.
  • the Fig. 6 shows the configuration of the contact sensor 1 as an ultrasonic sensor. This generates an ultrasonic signal which, depending on whether or not the detection peripheral region 18 is covered with material, is reflected differently and received in a corresponding receiver, for example also provided in the contact sensor 1, at a different level.
  • the Fig. 7 shows a constructed as a mechanical tact sensor contact sensor 1. This has an opening 34 in the roll shell 14 passing through the push-button 36, which, when the detection peripheral region 18 is covered by material, is displaced inwards.
