Definitions

  • the invention relates to a sample warping machine with a warping drum, which is connected to a winding drive, at least one yarn guide which is movable parallel to the axis of the warping drum, and a plurality of sub-rods which are fixed to the warping drum.
  • Such a pattern warping machine serves to produce a so-called pattern chain or short chain.
  • the warping drum is rotated.
  • the yarn guides (usually several yarn guides are present at the same time) then either pass the yarns around the circumference of the warping drum, where they are usually stored on conveyor belts, or they lead a thread in front of the front side of the warping drum, where he on a " Soul ", so an auxiliary transport device, is stored when it is not needed for the formation of the pattern chain.
  • crosshairs or sizing divisions are part bars intended.
  • the threads, which are wound on the circumference of the warping drum, are thereby partially guided radially outside and partly radially inside the part rods. Since the warping drum rotates, the part rods must be rotated with the warping drum. For this purpose they are attached to the warping drum or at least rotatably connected to the warping drum.
  • the threads are positioned relative to the part bars.
  • the partial rods are provided at their end face, at which the threads are fed, facing end with so-called fishing hooks. These fishing hooks, if a thread is to be performed radially outside the sub-bar, extended, otherwise they are retracted.
  • Another possibility is to use the thread guide to pass the corresponding thread at the tip of the dipstick when it is to be deposited below the dipstick, or to deposit directly on the dipstick.
  • the warping drum slowed down relatively quickly.
  • the partial rods and the already wound on the warping drum chain but have a certain mass, which opposes a rapid deceleration. It may therefore happen that in a rapid deceleration of the warping drum, the part rods leave their position and are no longer arranged at the intended in itself angular position. This can lead to problems when restarting the warping drum, because the threads are then no longer placed correctly in the part bars.
  • the invention has for its object to ensure reliable operation of the sample warping machine.
  • This object is achieved in a sample warping machine of the type mentioned above in that a sensor arrangement is provided which detects a position of the partial rods on the circumference of the warping drum.
  • the sensor arrangement thus determines at which angular position the partial bars are respectively arranged. It can thus determine whether the part-bars are arranged at the "right" angular position or whether the part-bars have left their intended angular position.
  • the sensor arrangement preferably determines the position individually for each partial rod, because the partial rods do not necessarily shift in a similar way in the case of a fault. Accordingly, the sensor arrangement for each partial rod can determine the angular position relative to the warping drum. In this case, it is preferable for the sensor arrangement to be opposite an end face of the warping drum. Thus, the sensor arrangement also "looks" at the end face of the part rods, which is released during archiving, that is not covered by wound threads. This makes it easy for the sensor assembly to recognize the part bars and to leave their position.
  • the sensor arrangement is opposite a peripheral surface of the warping drum.
  • the sensor arrangement detects the position of the part rods where the winding forms. In a combination of the two positions, the sensor arrangement can also look "obliquely" on the part rods.
  • the sensor arrangement is arranged stationary in the direction of rotation of the warping drum. So you only need a single sensor assembly to detect the positions of all the partial rods on the warping drum. This keeps the cost and burden of signal processing low.
  • the sensor arrangement is connected to a warning device.
  • the sensor assembly may generate a warning.
  • the warning device may, for example, generate an acoustic or an optical signal so that an operator can bring the corresponding partial rod back to its correct position.
  • a marker be mounted where the sub-rod should be located.
  • the sensor arrangement is connected to a control device which controls movements of yarn guides with the aid of which threads can be wound on the warping drum.
  • the thread guides can therefore take into account the angular deviations and deflect the guided thread at the correct angular momentum and place it in the part bars. A correction of the position of the partial rods is then not or not required with too great accuracy.
  • This embodiment has an advantage, especially when a change in the angular position of the partial rods can also result during operation, for example in the case of a rapid start-up of the warping drum.
  • the partial rods have markings which can be detected by the sensor arrangement.
  • a marking can thus be designed so that it is specially adapted to the sensor arrangement.
  • a light-emitting diode or another light source can be arranged on the partial rod, which can then be detected relatively easily by an optical receiver.
  • the marking may also have a special reflection behavior, which is tuned to a signal emitted by the sensor arrangement. It is then possible to configure the sensor arrangement relatively simply because it no longer has to recognize the partial rods per se, but can restrict itself to detecting the marking.
  • the sensor arrangement is designed as an active sensor arrangement.
  • the sensor arrangement thus has, for example, a transmitter and a receiver.
  • the transmitter emits a signal that can be reflected by the sub-bar or an associated element so that the receiver can detect it.
  • An active sensor arrangement can be relatively sensitive in many cases, so that the position of the partial bars can be detected with a higher accuracy.
  • the sensor arrangement preferably has a light source or an ultrasound source.
  • the light source may be formed, for example, as a laser source. With such signal sources, a contactless determination of the position of the partial rods on the circumference of the warping drum can be performed.
  • the sensor arrangement may have an image-giving device.
  • an image-giving device may for example comprise a camera which generates at certain times an image of a section of the front side of the warping drum. In such an image, one can then determine whether the partial rod is at the desired position or whether it has changed its position. In the latter case, one can also determine the degree of change.
  • the sensor arrangement detects an application height of threads on the warping drum.
  • the sensor arrangement can then additionally be used in order to make a statement about the structure of the forming on the warping drum To allow Wickels. For example, if you can see the current order level, you can control the thread feed so that there is a desired cone angle on the front side of the forming coil. This allows a similar operation to a section archipelago.
  • the sensor arrangement is connected to a drive device with which at least one partial rod can be displaced radially relative to the axis of the warping drum. You can then adjust the position of this partial bar relatively accurately to the maximum order height. This ensures that, on the one hand, sufficient space is available radially below the partial rod in order to accommodate the winding as such. On the other hand, you can then position the partial rod relatively close to the outer circumference of the coil, so that relatively little thread material is wasted and no excessively large free trains of threads are passed over the part of the rod.
  • the partial rods are connected at several axial positions via radial support arms with the warping drum, wherein the connection between a partial rod and a support arm is releasable and the support arm is movable away from the part of rod.
  • the threads are wound in the region of one end face on the circumference of the warping drum. They are moved with the help of conveyor belts or other movable transport surfaces parallel to the axis of the warping drum away from the front side. This creates space for new turns of the threads on the front side. This is repeated until the desired width the chain is reached. Since the part bars must be suitable for all possible warp widths, they must in principle go over the axial length of the warping drum.
  • a sample warping machine 1 has a warping drum 2, which is connected to a winding drive 3 shown schematically.
  • the winding drive 3 is able to turn the warping drum 2 during winding in the direction of an arrow 4.
  • a plurality of coils is arranged in a creel (not shown) in a creel (not shown). In the present embodiment, up to 128 coils can be arranged in the gate.
  • the yarn guides 6 can be moved so that the yarn guide eyelets 5 are guided over the warping drum 2 in the axial direction. There, the yarns guided by the yarn guide eyelets 5 are then deposited on conveyor belts 8, which form transport surfaces which move parallel to the axis of the warping drum 2 away from the end face on which the yarn laying unit 7 is arranged. If threads are not to be stored on the circumference of the warping drum 2, then the corresponding yarn guide eyelets 5 are moved in front of the end face of the warping drum 2. The threads not required for the production of the pattern chain are wound on a central cord (not shown).
  • part rods 9 are provided, which are arranged between conveyor belts 8.
  • Each partial rod 9 has at its end facing the yarn laying unit 7 end a tip 10, which has substantially radially outward.
  • the tip 10 is immovably arranged here on the partial rod 9.
  • the corresponding yarn guide eyelet 5 is moved in the axial direction so that the yarn comes to rest on the partial rod 9 on the side of the tip facing away from the yarn laying unit 7.
  • the thread guide eyelet 5 After passing the partial rod, the thread guide eye is moved back to its original position, so that the winding process can continue to progress.
  • a sensor assembly 11 is provided, which is arranged in front of the end face of the warping drum 2 and there "looks" at the end face of the warping drum 2, where the part rods 9 are arranged with their tips 10.
  • the sensor assembly 11 is held stationary, i. it does not rotate with the warping drum 2, but may for example be connected to a machine frame 12.
  • the sensor arrangement 11 can be designed such that it only ascertains that the angular position of the partial bars 9 has changed or not. If it detects a change in the angular position of a single sub-rod 9, it can trigger an alarm signal, such as an acoustic or an optical signal. In this case, an operator can restore the part bars before restarting the warping drum bring to the starting position.
  • This starting position may be marked, for example, by markings on the warping drum 2, so that the operator only has to bring the partial rods 9 back into conformity with the marking (not shown).
  • the sensor arrangement 11 can also be connected to the control, not shown, of the yarn guides 6.
  • the controller can take into account the deviation between the desired position and the actual position of the partial rods 9 determined by the sensor arrangement 11 when it actuates the yarn guides 6.
  • the partial rods 9 may be provided at their top 10 with a marker.
  • the sensor assembly 11 only has to recognize the marking and no longer the tip 10 of the partial rods 9 per se.
  • a marking may, for example, have a particularly well-reflecting behavior or it may even be a light-emitting diode or another signal generator whose signal is detected by the sensor arrangement 11.
  • the sensor arrangement 11 is preferably an active sensor arrangement.
  • the sensor arrangement 11 has a transmitter (not shown) which sends a signal, for example a light beam, such as laser light, or a sound beam, such as ultrasound, in the direction of the end face of the warping drum 2.
  • the sensor arrangement 11 has a suitable receiver which reflects the reflected light or the reflected light Sound is received. Since the tip 10 of the partial rods 9 has a different reflection behavior than the remaining region of the front side of the warping drum 2, a perfect detection of the angular position of the partial rods 9 on the circumference of the warping drum 2 is possible in this way.
  • the sensor arrangement 11 can be used to detect the application height of a coil forming on the warping drum 2.
  • This order level can be used to adjust the yarn advance, i. the movement of the yarn guide 6, so to control that results in an end face of the coil with a desired cone angle.
  • Such a cone angle is known per se and is therefore not explained in detail.
  • each arm is detachably connected to a partial rod 9. If you want to create a pattern chain with a large length, the order height will be correspondingly larger and you have to arrange the outer part of the bar with a correspondingly greater distance from the circumference of the warping drum 2, so that the corresponding part of the forming coil fits under this bar.
  • Each partial rod is held distributed over the axial length of the warping drum 2 at a plurality of positions on the warping drum 2. Since the conveyor belts 9 transport the wound yarns away from the end face of the warping drum 2 adjacent to the yarn laying unit 7, after a certain time the yarn winding comes into the area where the part bars are first connected to the warping drum, i. to the connection adjacent to the face. Before the winding reaches this connection, the connection between the holding arms and the part bars 9 is released and the holding arms are moved radially inwards, so that they do not obstruct the further advance of the roll away from the end face.
  • the sensor assembly 11 is in some way synchronized with the rotational movement of the warping drum 2, so that the sensor assembly can always detect at the "right" moment whether the part rods 9 are in the correct position or not.
  • the sensor arrangement 11 can also be embodied as an image-giving device which generates an image of a section of the end face of the warping drum 2 at specific times. In this picture, there is then a target position for the tips If the tip 10 of a sub-rod 9 is not at this target position, not only can one recognize that there is an error, but one can also see how large the deviation between the target position and the actual position is.
