Definitions
- the invention relates to a device according to the preamble of patent claim 1.
- DE-PS 2 716 024 is a device for measuring the on a rolling bearing acting radial force by means of elastically deformable members and an electrical Signal generator known. These devices are known as “force measuring bearings” available (brochure “Force transducers for FMS web tension measuring and control systems” from FMS Force Measuring Systems AG, Oberglatt / Switzerland). In the patent mentioned also referred to other devices for measuring radial bearing forces.
- the invention has for its object a device with the features of Preamble of claim 1 to improve, so that a more uniform ripple is reached and an adjustment of the force with which the second roller is acted upon, when changing the pressing force is not necessary.
- Two rollers 1, 2 which can be driven in the sense indicated by arrows are at the entrance a stuffer box 3 arranged.
- the axes of the two rollers 1, 2 are mutually parallel.
- the bearings of the first roller 1 are immovable with a machine frame 4 connected, which is only hinted at in the drawing.
- the bearings of the second roller 2 sit on a swivel arm 5, the swivel bracket 6 on the machine frame is articulated. By pivoting the swivel arms 5, the width of the between Rolls 1, 2 located gap 7 changeable.
- the stuffer box 3 has a rectangular cross section. It is made up of four wall panels enclosed, namely a pressure plate 9, a counter plate 10 and two side plates. These are parallel to the plane of the drawing and are not in the drawing shown. Like the counter plate 10, they are fixed to the machine frame connected.
- the pressure plate 9 is on each side with a rocker 11 to form a rigid unit connected. This is articulated on the swivel arm 5, so that the hinge axis with the Axis of the roller 2 coincides.
- a longitudinally extending lateral groove 12 of the pressure plate 9 serves as Guide for a sliding block 13.
- a rod 14 engages on this Press device on, for. B. the piston rod of a not shown, with the Machine frame connected piston-cylinder unit.
- At the output end of the Pressure plate 9 is laterally attached to an actuator 15 which by a coupling member 16th is connected to the slide block 13.
- a force sensor 17 is on the joint between the rocker 11 and the Swivel arm 5 arranged so that it acts on a perpendicular to the swivel arm 5 Responsiveness appeals.
- the sensor 17 is through a measurement signal transmission line 18 connected to the input of a controller 19.
- the controller 19 To transmit one of those Controller 19 formed control signal, the controller 19 through a line 20 to the Actuator 15 connected.
- the control signal of the controller 19 causes the control element 15 such a displacement of the sliding block 13 that the reaction force to one predetermined fixed value is adjusted.
- the sliding block 13 is always in one by the actuator 15 Positioned that there is a balance between that of the enclosed Thread material exerted on the pressure plate 9 back pressure on the one hand and the resulting force from the dead weight of the pressure plate 9 and the Piston rod 8 initiated pressing force on the other hand. In this way the Reactive force kept essentially at zero.
- the on the incoming bundle of threads normal force or band is therefore - apart from small Control fluctuations - constant, regardless of changes in the operating state.
- FIGS. 2 to 5 there is one Base plate 21 a machine housing 22, which has approximately the shape of a lying L. On the longer, horizontally lying leg is closely next to the vertically a bearing 23 for the lower roller 24 attached to the upper leg. At the the bearing of a swivel arm 25 sits at the upper end of the vertical leg.
- This has the shape of a hood with a sloping roof surface 26 and vertical Sidewalls 27. On the two sidewalls 27 are bearings 28 for the upper roller 29 attached. At the front end of the swivel arm 25 are on the two Sidewalls 27 tie rods 30 articulated. They are with piston rods 31 from Cylinder 32 articulated.
- swivel arm 25 With the swivel arm 25 is a rocker arm 33, which is similar to the swivel arm 25 hood-shaped with a slightly inclined roof 34 and vertical side parts 35 (FIG. 4) is articulated in a manner described in detail below connected.
- a pressure plate 36 is attached to the underside of the rocker 33. Is located between the pressure plate 36 and an opposing counter plate 37 the compression chamber 38. It is laterally limited by side plates 39.
- the force measuring bearing 41 consists of an inner ring 43, which is a Rolling bearing 44 for the shaft journal 42 receives, and an outer ring 45, which is fixed is connected to the bearing block 40.
- a gap 46 extends between the inner Ring 43 and the outer ring 45 over an arc of more than 300 °.
- To the Both ends of the gap 46 opens into a bore 47, the axis of which is parallel to Axis of the force measuring bearing 41 is aligned.
- the diameter of the bore 47 is significantly larger than the width of the gap 46.
- the web 48 is arranged horizontally, that is. he is in the Nine o'clock position. At two points in a vertical plane, i. H. in the Six o'clock position and in the twelve o'clock position, the gap 46 has two opposite semicircular recesses. In it sit with game bolt 49.
- a pull rod 50 on both sides connected by a hinge 51, consisting of a hinge pin 52 and one the tie rod 50 attached hinge eyelet 53.
- the two tie rods 50 are in essentially directed vertically and connected to piston rods 54 of cylinders 55, who sit under the base plate 21.
- the pivot pin 52 is in a horizontal groove in the side parts 35 of the rocker arm 33 guided so that it is displaceable in the horizontal direction. On the pivot pin 52 attacks a piston rod of a double-acting cylinder 56 on the underside the rocker 33 is articulated approximately in the middle.
- Strain gauges 57 are glued to the two sides of the web 48. This are integrated in an electrical measuring bridge in a known manner. If on the Shaft journal 42 acts a reaction force in the vertical direction, the web 48 on Bending stressed and deformed accordingly. The deformation causes one Strain on the strain gauges 57. This causes a strain on the measuring bridge generated electrical measurement signal, which is a measure of the deformation and thus for the Reaction force is.
- the measurement signal is fed to the input of a controller.
- the regulator compares the measurement signal with a specified reference variable and generates it corresponding to the determined difference, control signals for valves that control the pressure medium supply to the double-acting cylinder 56 in the sense of negative feedback influence, so that the determined difference between the measurement signal and the command variable is reduced. This makes the reaction force depending on the choice of the command variable adjusted to zero or to a desired fixed value.
- the bolts 49 protect the web 48 from permanent deformations by Overload act as stops
