Definitions
- the method is characterized by the following steps: b) directly or indirectly determining and storing the radial distance of the segment in the operating position with respect to a fixed reference position at different times during the period of use; c) evaluating the distances stored at the different times with regard to whether they exceed a predetermined upper threshold value or fall below a predetermined lower threshold value during the period of use of the reel device; and d) indirectly detecting a state of wear of the reel device if the recorded radial distances exceed the upper threshold value or fall below the lower threshold value from one of the times.
- the controlled operating positions at the later time of use no longer correspond to the operating positions as they were controlled at the first time of use, e.g. when the reel dome was in new condition.
- the difference in the controlled operating positions is reflected in changing distances between the controlled operating positions and fixed reference positions over the service life of the reel dome.
- determining ... the radial distance is to be interpreted broadly. “Determining” includes in particular measuring and/or simulating the radial distance.
- the present invention assumes that the compression spring unit is not subject to wear.
- the present invention provides for an at least temporary intelligent evaluation of the distances between the segments in an operating position compared to a fixed reference position during their service life, preferably starting with the new state or a comparable fault-free state after maintenance.
- the method according to the present invention allows an accurate statement to be made on the basis of these stored distances regarding the wear pattern of the main wear parts of the reel mandrel.
- the user of the reel mandrel can recognize a gradual wear of internal components of the reel mandrel quite precisely and thus carry out a targeted change or a targeted Schedule maintenance of the coiler mandrel during an upcoming downtime of the coiler mandrel without having to take the system out of operation excessively.
- the first operating position is a pre-spread winding position of the segment without wound band. If, over the course of the service life of the reeling device, when approaching the winding position, an increasing increase in the distance of the segment in the winding position compared to the fixed reference position is determined, then according to the invention, a conclusion is drawn about the state of wear in the form of an undesirable elongation of the lashing and/or a deflection of joint holes on the lashings and/or wear on the fastening bolt with which the lashings are articulated on the control rod. This applies in particular if the stored distances exceed the specified upper threshold value, or vice versa.
- the second operating position is a winding position of the segment in which at least one turn, preferably a plurality of turns of the strip are already wound onto the segment and the reel mandrel. If, for this operating position, an increasing reduction in the distance of the segment compared to the stationary reference position located radially further inside is determined over the period of use of the reel device, the method according to the invention provides that the state of wear is inferred in the form of undesirable abrasion on the surface of the ramp on the outside of the control rod and/or on the underside of the housing of the compression spring unit. This applies in particular if the distances stored over the period of use fall below the predetermined lower threshold value.
- the distance of the segment in the discharge position compared to a reference position located further radially inward is still minimal. Due to an undesirable elongation of the tabs and/or an undesirable deflection of the joint holes on the tab and/or wear of the fastening bolt with which the tab is hinged to the control rod, this distance becomes larger and larger as the reel mandrel is used for longer. If the stored distances exceed a predetermined upper threshold value over time, then this is an indication within the meaning of the invention that at least the tabs may exhibit the aforementioned signs of wear and should therefore be replaced.
- Fig. 1 a reeling device
- Fig. 2 a compression spring unit with its characteristic curve
- Fig. 3 is a longitudinal section through a reel mandrel with the segments in a first operating position without wear;
- Fig. 4 shows the longitudinal sectional view according to Fig. 3 with the extended segments in the first operating position with existing wear
- Fig. 6 a longitudinal section through the coiler mandrel with the segments in a second operating position without wear
- Fig. 8 is a diagram illustrating the temporal change of the distances A2 during the service life of the reel dome
- Fig. 9 is a longitudinal sectional view of the reel mandrel with the segments in a third operating position without wear
- Fig. 10 the longitudinal section according to Fig. 9 with existing wear.
- Fig. 11 shows the change of the distance A3 during the service life of the reel dome.
- Fig. 3 shows a longitudinal section through the reel mandrel 120 in detail.
- the compression spring unit 150 can be seen, which presses against the segment 124 from below with the pressure force FD exerted by it and in this way holds the segment under a radial preload.
- the compression spring unit 150 is guided in the radial direction R and slides with the sloping underside of its housing 153 on a ramp 123 of the control rod 122.
- the control rod 122 is moved in the axial direction L, the aforementioned sliding movement occurs and the compression spring unit 150 is thus moved in the radial direction.
- the surface or top of the housing 153 of the compression spring unit 150 forms an upper or inner stop for the compression of the compression spring unit. This means that at maximum compression, the segment 124 rests on the surface of the housing 153 of the compression spring unit 150.
- Figs. 3, 6 and 9 each show the coiler mandrel in a wear-free state, while Figs. 4, 7 and 10 show the coiler mandrel with wear.
- the method according to the invention provides that the segment 124 is moved several times over the service life of the reel device into a first operating position P1, also called the start-up position.
- the radial movement takes place under the preload applied by the compression spring unit 150.
- the segment 124 is moved a little way in the radial direction compared to the collapsed state of the reel mandrel, specifically to a distance A1 compared to the fixed reference position PO.
- the radial distance A1 is determined and stored at different times over the service life.
- Fig. 5 illustrates the temporal development of the distances A1 over the course of the service life of the reel mandrel 120. It can be seen that the measured distances A1 at an early point in time, when the tabs 125, 126 are not subject to any or only slight wear, are smaller than at a later point in time, when the tabs are subject to wear.
- Fig. 5 shows schematically the distances determined at different points in time, with each black dot corresponding to the distance determined at a specific point in time. Over time or over the service life of the reel mandrel, a shift of such a cluster of measured values towards larger distances can be seen. In practice, it is advisable to determine average values of the distances A1 in certain time windows and to evaluate these instead of the large number of individual measured values.
- the radial extension state represented by the distance A2 of the segment 124 compared to the fixed reference position PO, decreases continuously over the service life of the coiler mandrel, see Fig. 8. As soon as the wear has reached a certain level, the radial distance A2 to the lower distance threshold value S2 or below. If the evaluation of the radial distances according to the method according to the invention detects this situation, it is concluded that there is severe wear on the said sliding surfaces and a corresponding recommendation is issued to replace the control rod 122 and/or the housing 153.
- Fig. 9 to 11 relate to a third operating position for the reel mandrel, the so-called discharge position.
- Fig. 9 shows a wear-free state;
- Fig. 10 and 11 relate to the state with wear.
- This position of the segments is the discharge position mentioned, represented in Fig. 9 to 11 by the radial distance A3 from the fixed reference position PO.
- the distance A3 recorded at various times during the service life of the reel mandrel 120 is also suitable for indirectly detecting a state of wear of the tabs 125, 126, of their joint holes 127 and/or of the fastening bolts 121.
- the control rod 122 is moved to the right, whereby the compression spring unit 150 is slidably lowered on the ramp 123 to the distance A3.
- the radial distance A3 or the third operating position is below a predetermined second upper threshold value S3.
- this radial distance A3 increases over the service life of the reel mandrel 120 with increasing wear.
