Definitions

  • the invention relates to a sensor system, in particular for a ring spinning machine with a ring frame.
  • the invention is particularly concerned with the design of components which are intended to enable the so-called single spindle sensor system to be implemented.
  • Optical sensors are known from EP-A-480 898 and DE-A-2334389.
  • EP-A-480898 shows in a schematic diagram (FIG. 1) a sensor design which is intended to detect light reflected by the runner, and two sensor designs (FIGS. 2 and 3) which are triggered by the interruption of a light beam by a moving element (e.g. runner or thread) work in a spinning station.
  • a moving element e.g. runner or thread
  • FIG. 1 For the designs that work on the basis of the interruption of a light beam, not only basic sketches but also construction details have been shown and described. For the arrangement according to FIG. 1, however, only the schematic diagram is given in EP-A-480898.
  • FIGS. 4 to 6 of EP-A-480 898 show an assembly unit for the embodiment according to FIG. 2 in the same document.
  • This unit comprises a U-shaped hollow profile, which should grip the individual sensor heads elastically.
  • the heads
  • EP-A-480898 also mentions DE-A-2334389 as a previous publication of an optical sensor, which can be provided in the form of a light barrier or a reflection head.
  • DE-A-2334389 does not primarily deal with the sensors, but rather with a speed control for a ring spinning machine.
  • An optical sensor is only mentioned as a variant among others and it is already clear from the schematic illustration (FIG. 3) of such a sensor that hardly any serious thought has been given to the implementation.
  • the claimed solution offers the advantage that the (mutual) geometric relationships of the transmitter and receiver elements of a spinning station can be predetermined and the final assembly can thereby be facilitated.
  • the present invention can be used in combination with the invention according to EP-A-1052314 and / or EP-A-1074645. Certain details of the exemplary embodiments in these applications must be adapted for this purpose.
  • FIG. 1 shows a cross section through a ring frame with the surrounding parts of a ring spinning machine according to DE-A-195 42 802,
  • FIG. 2 shows a copy of FIG. 11 from EP-A-1074645
  • FIG. 3 schematically shows a perspective illustration of a solution according to the present invention, parts being broken away in order to be able to show the parts underneath;
  • FIG. 3a shows a modification of the arrangement according to FIG. 3;
  • Fig. 4 shows a detail (a housing) from Fig. 3 viewed in the direction of arrow P (Fig. 3) with part removed from the housing to show the cavity within the housing;
  • FIG. 5 shows the housing of FIG. 4 viewed from below
  • FIGS. 4 and 5 shows the housing of FIGS. 4 and 5 viewed from the side;

  • FIGS. 10A to 10D different variants of a lens optic for a housing according to FIGS. 4 to 7.
  • the ring frame 110 in FIG. 1 has a horizontal support part 113 for a spinning ring 112, further to the inside of the spinning machine a support part 111, to which a rail 120 is fastened, which carries a holder 122 and a ring 124 for constricting the thread balloon.
  • each spindle 116 with its cop 118 is assigned a spinning ring 112, a holder 122 and a further ring 124 in a bore 125 of the ring frame 110.
  • a spinning ring 112 is held on the ring frame 110 by a holder 114.
  • openings 126 are provided in the support part 111 and strips 128 are provided, which extend below the support part 113 from the support part 111.
  • the openings 126 enable the air flowing along the cops according to arrows 140a, 14Ob to be diverted.
  • the ring frame according to FIG. 1 is only shown as an example - the actual construction plays no essential role for this invention.
  • the ring frame 150 in Fig. 2 carries a spinning ring 180, with a rotor 190, and ring holder 184.
  • the spinning ring 180 shown in Fig. 2 is formed as a so-called "inclined flange ring" (eg according to EP-B-528 056).
  • the invention can but can also be used with other ring types (for example with the conventional ring cross section according to FIG. 1.)
  • a base part 330 is fastened to the front side 156 of the ring frame by suitable means (not shown).
  • the base part comprises two walls 334, 336 protruding from the ring frame. each wall being provided with an inner bead 338 at the end distant from the ring frame.

  • the holder 344 can be formed from plastic. It also includes a bezel 352 for a signal lamp 348.
  • the connecting elements 340, 342 also serve as fastening elements for a signal evaluation unit SA, which is connected to the display 348 and to the sensor 346 by means of conductors 354, 356.
  • the bracket 344 therefore also serves as a partial cover for the channel within the base 330.
  • sensor 346 is preferably designed as a magnetic sensor.
  • This version has proven itself technically. However, it turned out that this choice of sensor element has a decisive influence on the total costs and that it is very difficult to offer the end product (1000+ sensors with evaluation electronics, cabling and operator guidance) at a price that is attractive to the buyer of the ring spinning machine is. Optical sensors can be bought cheaper. However, as has already been shown in the introduction, there is currently no version known to the applicant with reflection heads as rotor sensors.

  • the parts 117 are the so-called “separators", which shield the surroundings of a spindle 116 (a "spinning station") from the surroundings of the neighboring spindles 116 ("spinning stations") as far as possible.
  • Parts of the spinning rings 180 for five spinning positions can also be seen in this figure.
  • a U-shaped profile 200 is attached to the front side 156 (only visible on the left) of the ring frame and, like the base part 330 (FIG. 2), forms part of a channel.
  • the profile 200 has broken away at the left end in order to show the ring frame underneath.
  • the type of attachment is not particularly important because the system to be described is insensitive to small tolerance errors.
  • the attachment of the profile should be carried out in such a way that the upper (free) edge of the profile 200 lies in one plane with the contact surface 113.
  • the profile 200 is open at the top, the channel is therefore closed by cover elements (“sensor carrier”) 202 according to the present invention, two cover elements being partially shown in FIG.
  • Each cover element 202 comprises a cover plate 204, an edge strip 206 of which rests on the support surface 113, and two elastic fastening strips 208, 210 which project downward into the channel and form a snap connection with the side walls of the profile 200.
  • the fastening strip 208 forms the lower part of a wall which has a stop 207
  • the strip 210 forms the lower part of a wall 211 which has a stop 209.
  • the stops 207, 209 come into contact with the free edges of the profile 200 and thus define the angular position of the cover plate 204 with respect to the contact surface 113.
  • Each cover plate 204 carries four housings 212, only one housing 212 of the left cover element 202 and three housings 212 of the right cover element 202 being visible in FIG.
  • the angular positions of the housings relative to the support surface 113, or relative to the spinning rings mounted on the support surface, are given by the angular position of the respective cover plate 204.
  • the housings 212 are described in more detail below with reference to FIGS. 4 to 7, wherein they are all identical, so that the description of one housing applies to all others.
  • Each housing 212 comprises two side walls 214 and 216 (FIG. 4) and a roof part 218.
  • the housing is designed without a floor, ie it is completely open to the cavity of the channel.
  • the side walls 214, 216 protrude beyond the edge strip 206 and are connected in this protruding area (in the “front part” of the housing) by a base 220 (FIG. 5), so that the housing 212 is closed off from the outside.
  • the “end face” 224 that is to say the housing wall, which faces a spinning ring 180 assigned to this housing, is formed and is specially designed according to the teaching of certain subclaims explained in more detail below. For now, however, the description of the general construction of the housing will be completed.
  • housing 212 i.e. the housing wall, which faces the service alley between two adjacent machines, is formed by a curved wall part 226, which has been removed in FIG. 4 in order to allow an insight into the cavity of the housing.
  • the wall 211 is provided with a suspension 228 and two stops 230.
  • an electronic board 232 according to FIG. 8 can be mounted in a predetermined position opposite the front side 224 of the housing.
  • the electronics board 232 is similar in basic concept to the board that was described in connection with EP 1074645 (FIGS. 12 and 13), ie it comprises a carrier with a computer and conduction paths between the computer and other electrical elements of the electronics. Since these elements or the lines themselves are not essential for this invention, they have not been shown.
  • this circuit board 232 is provided with an opening 234 which can accommodate the suspension 228 when the circuit board 232 is printed "forward" (in the direction of the end face 224). The board 232 should be pushed forward so far that it abuts the stops 230.
  • the opening 234 and the suspension 228 are constructed in such a way that a certain clamping force is generated between them when the board 232 is in contact with the stops 230.
  • the board 232 differs from the boards of EP-A-107645 in that it has a light transmitter element 236 (FIG. 7), a light receiver element 238 (FIGS. 7 and 8) and a light-emitting diode LED as a signal transmitter for the operator guidance is equipped.
  • the transmitter element 236 is accommodated in a "pocket” 240 provided for this purpose in the front part of the housing when the board 232 is in contact with the stops 230, while the receiver element 238 is accommodated in an adjacent "pocket” 242 becomes.

  • the diode LED is attached to the other side of the board and faces the wall part 226.
  • a separate (i.e. a respective, associated with this element) "window” 240, 242 (FIGS. 4 and 7) is provided in the front side 224 for both the transmitter 236 and the receiver 238.
  • These windows 240, 242 are at least selectively "translucent", i.e. they let through the radiation that should be emitted by the transmitter and collected by the receiver.
  • the term "light” is not restricted to visible electromagnetic vibrations
  • the term here also includes the low-energy radiation, which can also be used in the monitoring of machines operated by humans, in particular the regions of the infrared and ultraviolet spectra adjacent to the visible range.
  • the transmitter 236 in the embodiment according to FIGS. 4 to 7 preferably emits in the infrared range, for example with a wavelength in the order of 850 nm to 950 nm.
  • translucent does not necessarily mean absolute transparency here. A certain damping (absorption) of the emitted energy is permissible if the receiver shows sufficient sensitivity.
  • the material of the window can be selected in such a way that it produces a filter effect and is therefore selective transmits certain wavelengths (predetermined by the choice of the transmitter). For example, the material could be chosen such that it is practically opaque for wavelengths outside the infrared range. However, this additional measure is not essential to the invention.
  • the wall parts adjacent to the windows preferably have a relatively low light transmission. This applies not only to the side walls 212, 214 and roof part 218, but also to the partition 244 between the "pockets" which accommodate the transmitter 236 and receiver 238. This measure counteracts a "short circuit" (crosstalk) between the transmitter 236 and the receiver 238.
  • the relative permeability of the wall parts does not have to be achieved by the selection of the material, but can (also) be determined by the wall thickness. Both measures (selection of the material and selection of the wall thickness) are preferably used in order to achieve the required effect.
  • the front part of the housing is preferably formed from a single material and expediently in one piece. The preferred material is a plastic, for example a polycarbonate.
  • the windows can have a wall thickness in the range of 0.5 to 1.5 mm, while the relatively impermeable wall parts have a much greater thickness.
  • the diode LED should emit visible light, as this element serves as part of the operator guidance.
  • the concept of the operator guidance system has already been explained in EP-A-1074645 (FIGS. 8 to 10) and the description is not repeated here. What is important for this system is a visually perceptible signal that indicates that an error has occurred at an affected spinning position.
  • the housing 212 is also intended to serve as a display means.
  • the signal is generated by the diode LED lighting up.
  • the rear wall 226 must therefore be translucent - for visible light.
  • the alarm or call signal that is output by a specific spinning station should only be perceptible by an operator within a predetermined space around this spinning station - the side walls 214, 216 in the rear part of the housing 212 are therefore also essentially for the radiation impermeable, which emanates from the diode LED.
  • the shape of the side walls 214, 216, especially in the rear part of the housing, is selected in relation to the position of the diode LED within the housing such that an operator only perceives the signal when he enters the predetermined detection field near the spinning position.
  • the “geometry" of the sensors in a spinning station according to FIG. 3 will now be explained with reference to FIG.
  • the board 232, the transmitter 236 and the receiver 238 are also shown in FIG.
  • the housing 212 has been omitted because it is assumed that the windows 240, 242 are transparent to radiation, while the partition wall is radiation-opaque.
  • the transmitter is provided with its own optics by the manufacturer, so that this element generates a beam 250 (indicated by dashed lines), which spreads out conically and symmetrically about an axis 251.
  • the receiver 238 naturally does not generate a beam, but has one assigned to it "Touch field", which also spreads conically with increasing distance from the receiver, namely symmetrically about an axis 253 - the conical spread of this touch field is indicated by dashed lines in FIG. 9 with 252. It is first assumed that the axes 251, 253 are mutually parallel with a distance s. The figure does not show the angular position of the axes 251, 253 with respect to the contact surface 113 - it is assumed that the axes run parallel to the surface 113.
  • a segment of the "surface" of the spinning ring 180 is indicated by F in FIG. According to FIG. 9, this segment is located at a distance A both from the transmitter 236 and from the receiver 238.
  • Reference numeral 254 indicates a leg of the rotor 190 which moves in the direction of the arrow R, guided by the spinning ring 180. It is assumed that the runner 190 penetrates the touchpad of the receiver 238 at the time To. This intrusion will not change the state of the Trigger receiver 238, or the sensor system, because the peripheral area RG, in which the rotor 190 first penetrates the touch pad 252, is not irradiated by the transmitter 236. Only and if the leg 254 penetrates into the area U, in which the touch pad 252 of the receiver 238 overlaps the cone 250 of the transmitter 236, will the sensor system react to the rotor 190.
  • the axes 251, 253 could e.g. Approach in the direction of the spinning ring and cut at a point on segment F if necessary.
  • the distance s should be kept as small as possible without risking the "short circuit" (direct transmission from the transmitter to the receiver).
  • the distance A would also have to be kept small.
  • the distance A must not be chosen too small in terms of spinning technology.
  • the approach of the housing 212 to the spinning ring 180 could cause a disruption in the yarn path, further this approach is limited by the need to be able to operate the spinning station.
  • a distance A of less than 10 mm is therefore problematic in all cases and should therefore preferably be avoided.
  • This distance is preferably more than 15 mm, a distance of 20 mm or more is expedient.
  • the importance of the angular position of the axes 251, 253 relative to the contact surface 113 increases. The larger the distance A is chosen, the more precisely this angular position must be determined in order to avoid that the beam 250 either falls on the surface 113 in front of the spinning ring or spreads uselessly above the spinning ring in the area of the thread balloon.
  • the diameter of the spinning ring in a ring spinning machine for processing short staple fibers can normally be selected in the range from 35 to 50 mm by the end user.
  • the machines that process long staple fibers work with larger ring diameters.
  • the radiation-emitting surface of the transmitter 236 should be brought as close as possible to the window 240 (FIG. 7) without coming into contact with the window 240. No substantial distance should be left between the transmitter 236 and the inner surface T1 (FIG. 4) of the transmitter pocket. It is therefore advantageous to design the surface T1 with a small taper, so that the transmitter 236 comes into contact with the surface T1 just before it would touch the window. Such a conical shape of the surface. T1 is indicated schematically in FIG. 4 with a dashed circle.
  • the light-sensitive area of the receiver 238 preferably has a somewhat greater distance from the overlap area U than the distance A of the transmitter 236. This can be ensured by a small distance a (FIG. 7) between the light-sensitive area of the receiver and the window 242 is released. This can also be ensured in that the receiver 238 comes into contact with a conical surface T2 (indicated schematically in dashed lines, FIG. 4) of the receiving pocket and / or that the receiver 238 is provided with a hood 256 (FIG. 7) which comes into contact with the window 242.
  • the window 242 and / or the window 240 can be designed as a lens. Different lenses are possible, with FIG. 10 showing the following examples:
  • 10A - convex outer surface the inner surface lies in one plane (plano-convex lens); 10B - outer surface convex, inner surface also convex;
  • Fig. 10D concave outer surface, inner surface lies in one plane (Plano-concave lens).
  • outer surface refers to the surface that is on the outside of the housing 212.
  • the “inner surface” lies within the cavity of the housing 212.
  • the curvature of the outer surface can, but does not have to, for the two lenses (windows) 240, 242 - i.e. for the sender as well as for the receiver - be the same.
  • housing 212 forms a so-called multifunctional monolithic housing. At least the protection and / or positioning and / or light-bundling functions can be integrated in this monolithic housing, but preferably also the display function, which shows a defective spinning position.
  • the display can be designed in such a way that it shows both a thread break as well as a spindle which indicates the wrong speed (for example a creep spindle, cf. EP-A-1074645)
  • the preferred manufacturing process is to form the plastic cover elements 202 entirely in one piece in an injection molding process. This is also possible if the rear wall 226 has to be formed from a different material than the side walls 214, 216 and roof part 218, for example in order to give a specific color of the alarm or call signal.
  • the housings 212 could, for example, be manufactured individually and connected by intermediate pieces to form a cover element. Such housings could be glued to the spacers, for example.
  • the invention is not restricted to use in the ring spinning machine and also not, in the ring spinning machine, to scanning the rotor.
  • FIG. 3A shows schematically in plan another embodiment of the principle of the selective delivery of an optical signal for operator support.
  • the optical signal In the case of the housing 212, provision is made for the optical signal to be delivered selectively within a limited space in the vicinity of the spinning station. Under certain circumstances, however, it is necessary to emit a signal "over a wide area", the signal generation in the immediate vicinity of the light source no longer being important because at least one other signal transmitter is present in this room.
  • These requirements apply to the "section lamp”.
