Definitions

  • the invention relates to a device and a method for storing a thread of limited length spun on a spinning machine with a suction pipe connected to a vacuum line for detecting and guiding the thread by means of suction air and a thread storage chamber arranged between the vacuum line and suction pipe, into which the thread can be sucked in and against Suction direction is removable, as well as for cleaning the device mentioned and to shut off the suction air flow from the suction pipe.
  • Thread stores of a known type are used, for example, in spinning machines with high thread take-off speeds, as is the case with rotor, friction or air spinning machines. These spinning machines require a thread storage device that can accommodate a large length of thread when piecing or removing a broken thread. A large length of thread is produced during the preparation time for piecing or thread breakage elimination, which must be stored temporarily.
  • the thread must be stored in the smallest possible space, since only limited space is available on the spinning unit or in the piecing carriage. When storing the thread, make sure that the thread can be removed easily, without curling and without breaking the thread at the required time. Thread breakage can occur during the pull-off process if the friction on the wall of the thread accumulator becomes too great, or if tangled thread layers have formed which prevent the thread from being pulled off due to overlaps and ball formation.
  • Known thread stores consist of suction tubes that capture the thread through the suction air flow and absorb it.
  • the suction pipe must have the same length as the thread to be stored. Curvatures in this suction tube, which would significantly reduce the space requirement, have a disadvantageous effect on the retaining force that acts on the thread and increase the risk of thread breakage already mentioned.
  • the object of the present invention is therefore to provide a method and a device, whereby in a simple manner and without the disadvantages described, a thread of greater length can be ordered in a small space and this thread can be pulled back against the recorded direction without problems.
  • the thread storage chamber 11 is arranged in a body 1 which is rotatably mounted, and by a method according to claim 12.
  • the advantage is achieved that the thread storage chamber can be sucked in in different directions from a suction pipe. This has the effect that impurities or thread remnants which are no longer to be used can be removed from the thread storage chamber and thus do not impair the storage capacity of the thread storage chamber.
  • the advantage is also achieved that thread that is no longer mechanically, e.g. can be detected at at least one end, can be removed pneumatically from the thread storage chamber.
  • the thread to be stored can thus always be stored on a cleaned collecting surface, which on the one hand reduces the risk of damage and on the other hand essentially the same thread length can be stored with each storage process.
  • the storage area in the thread storage chamber is advantageously on the base of the conical thread storage chamber. This provides a large area on which a large length of the thread can be stored. If the thread storage chamber is delimited at one end by a screen surface, it is ensured that the thread receives an orderly deposit on the screen surface. The thread is stored on the sieve surface until the sieve surface is completely occupied and therefore no suction air sucks the thread. If the thread storage chamber is delimited at its conically widened end by a sieve surface, a large thread length can advantageously be stored, since a large storage surface is available. Both a thread end and a thread loop can be stored on the storage area.
  • An orderly depositing of the thread on the sieve surface without the risk of the thread becoming tangled can advantageously be achieved through openings in the sieve surface, the cross section of which is less than or equal to the thread cross section. If the openings were larger than the thread cross-section, thread loops would form through the openings of the sieve surface, which could result in damage to the thread when removed from the thread store.
  • the screen surface can be moved from a storage position into a cleaning position by rotating the body. This has the advantage that the screen surface can be sucked from different directions without the suction pipe having to be moved. The storage side of the screen surface can thus be sucked on the one hand from the bottom and on the other hand from the top. In this way, thread residues and impurities are removed from the screen surface in the cleaning position and suctioned off through the suction pipe.
  • the body serves both for receiving the storage chamber and as a closure member for the suction pipe.
  • the suction air can be switched off in the suction pipe by rotating the body into a blocking position.
  • the body lies completely against a sealing surface and thereby blocks the connection between the intake manifold and the vacuum line.
  • the rotatably mounted body can be locked in at least one of the positions for storing, cleaning or locking, then it is ensured that the respective function of the body is reliably maintained. If the suction air flows at least in the storage position through the thread storage chamber into the vacuum line, it is ensured that the thread to be stored is sucked into the thread storage chamber only. A deposit of the thread outside the thread storage chamber, possibly due to incorrect air that would flow along the side of the body, can thereby be avoided.
  • the suction air advantageously flows exclusively through the thread storage chamber and not since not along the outer surface of the body into the vacuum line.
  • suction pipe reaches right up to the body, it is advantageously ensured that the thread is passed directly from the suction pipe into the thread storage chamber. A lateral depositing of the thread outside the thread storage chamber is avoided.
  • the thread storage chamber By designing the thread storage chamber in such a way that the suction air flows through the thread storage chamber in the storage position of the body without swirling, an orderly depositing of the thread in the thread storage chamber is advantageously achieved.
  • the formation of eddies in the thread storage chamber would lead to the risk that unintentional loops would form before being deposited on the storage surface, as a result of which the pulling of the thread from the storage chamber in an orderly manner could lead to thread damage or thread breaks.
  • the thread for storing is captured by the suction air flow, sucked through the suction pipe into the thread storage chamber and attached to a collecting surface of the thread storage chamber. If the suction air flow in the suction pipe is weakened by the thread layer accumulating on the collecting surface, further suction of additional thread is gradually prevented. Following the storage process, the thread is drawn out of the suction tube and the thread storage chamber through the suction tube in the direction opposite to the thread suction direction. If a rotatably mounted body containing the thread storage chamber is rotated in such a way that the suction air flow flows through the thread storage chamber counter to the thread suction direction, the thread storage chamber and the collecting surface are thereby cleaned of thread remnants and dirt.
  • the thread is stored in a very small area.
  • the length of the thread to be stored is predetermined by the size of the collecting area that is vacuumed. There is therefore no need for an additional device which prevents suction of the thread after a certain thread length.
  • the quilt is turned by the Body sucked from the back, whereby the thread remnants and dirt are released from the collecting surface and directed into the suction.
  • the next storage process on the collection surface is in turn carried out on a cleaned collection surface, which ensures that each storage process has the same capacity after cleaning.
  • the rotatably mounted body is rotated in such a way that the suction air flow in the suction pipe is interrupted, energy savings are advantageously ensured since the suction can be limited to the storage and cleaning process. In addition, no additional devices for shutting off the suction air flow are required.
  • FIG. 1 The position of a thread storage chamber 11 shown in FIG. 1, which is located within a rotatably mounted body 1, causes a thread 2 that has reached the mouth region of the suction tube 3 to be sucked through the suction tube if the vacuum in the suction tube 3, thread storage chamber 11 and vacuum line 4 is sufficiently strong 3 into the thread storage chamber 11.
  • An air flow through the thread storage chamber 11 takes place in the longitudinal direction from the mouth of the thread storage chamber 11 to a screen surface 12.
  • the thread 2 collects on the Sieve surface 12 which delimits the thread storage chamber 11 in the flow direction D until the sieve surface 12 is completely covered by the thread 2.
  • the size of the screen surface 12 has an influence on the thread length to be stored.
  • the sieve surface 12 is located on the largest cross section of the conical thread storage chamber 11.
  • the conical thread storage chamber 11 creates a connection between the sieve surface 12 and the suction pipe 3.
  • the suction pipe 3 has a substantially smaller cross-sectional area than the sieve surface 12. This causes a large suction force in the suction pipe 3, whereby the gripping and vacuuming of the thread 2 from e.g. a spool is facilitated.
  • the end of the suction pipe 3 located on the rotatably mounted body 1 is arranged in the immediate vicinity of the inflow opening of the thread storage chamber 11. This prevents the thread 2 from accidentally entering the space between the suction pipe 3 and body 1 and breaking when it is pulled off. This is further supported by the fact that a suction air flow must always flow through the screen surface 12 and the thread storage chamber 11, since the rotatably mounted body 1 and the suction pipe 3 are each sealed at the outer diameter by seals 52, 53 with respect to the vacuum line 4.
  • the seals 52, 53 are fastened in a carrier 5 which is movably mounted in one direction.
  • the support 5 with the seal 52 is pressed against the body 1 by a spring 51 which is supported in the cover 41 of the vacuum line 4, the seal 52 preventing suction air from entering the thread storage chamber 11 from the side.
  • the seal 53 prevents suction air from entering between the carrier 5 and the suction pipe 3.
  • the body 1 is connected to an axis of rotation 14.
  • the flow direction D of the suction air through the thread storage chamber runs essentially at right angles to this axis of rotation 14 in the storage position shown in FIG. 1.
  • the screen surface 12 is arranged parallel to this axis of rotation 14 and connected to the body 1 by screws 13.
  • the axes of rotation 14 of the rotatably mounted body 1 are mounted in the housing of the vacuum line 4.
  • the bearings 15 must ensure a largely sealing effect to the outside so that the pressure losses are low.
  • a handwheel 6 Connected to the axis of rotation 14 is a handwheel 6, on which there are three ball pressure pins 61 as locking means, of which only two are shown in FIG. 1.
  • the ball pressure pins 61 snap into a recess of a locking element 62 and lock the rotatably mounted body 1 in three positions.
  • the ball pressure pins 61 are adjustable in their pressure strength, so that a secure locking of the body 1 is ensured in each of the three positions.
  • the three lockable positions essentially correspond to the positions of the rotatably mounted body 1 shown in FIGS. 1 to 3.
  • the rotatably mounted body 1 is not actuated by a handwheel 6, but is driven by a motor or pneumatic element.
  • Another option for the drive is actuation via a lever mechanism.
  • the position of the rotatably mounted body 1 can thus be controlled at a location other than directly on the vacuum line 4, for example by a movable piecing machine.
  • each drive element is to be regarded as suitable, which is able to assume various operating positions, also with the aid of gears, and to hold the body 1 in the respective position over a certain period of time.
  • the handwheel 6 is pressed with a nut 18 onto an annular collar 17, as a result of which it is fastened on the axis 14.
  • the axis 14, to which no handwheel 6 is attached, is secured with a locking ring 16 against unintentional axial displacement.
  • Fig. 2 shows a position of the thread storage chamber 11, in which the screen surface 12 and the thread storage chamber 11 are cleaned.
  • the flow direction D in the thread storage chamber 11 and on the screen surface 12 is opposite to the flow direction D of the position shown in FIG. 1, whereby thread residues and contaminants 21 are released from the screen surface 12 and sucked into the vacuum line 4. From here they get into known and therefore not shown filters or waste containers.
  • the seal 52 acts on the rotatably mounted body 1, so that the screen surface 12, as in the position in FIG. 1, is only sucked from one side. This ensures that the thread remnants and dirt 21 can quickly detach from the screen surface 12, since a large suction force acts on them.
  • Fig. 3 shows the locked position of the thread storage chamber 11, in which the suction pipe 3 is blocked by the suction air flow.
  • the seal 52 encloses the rotatably mounted body 1 in such a way that no suction connection between the suction pipe 3 and the vacuum line 4 is established by the thread storage chamber 11 and the screen surface 12.
  • Thread storage chamber 11 and screen surface 12 in the illustrated embodiment on the side of the vacuum line 4.
  • the rotatably mounted body 1 is in a position between the position shown in FIGS. 2 and 3, so that the screen surface 12 or the mouth of the thread storage chamber 11 extends over the seal 53 such that a direct connection between the suction channel 3 and the vacuum line 4 exists, thread remnants and dirt 21 which have accumulated in the space between the suction pipe 3 and the rotatably mounted body 1 are removed.
  • the shape of the rotatably mounted body 1 is not limited to the embodiment shown. However, it must be coordinated with the seal 52 and the axis of rotation 14 in such a way that, at least in the storage position and the blocking position, the seal 52 lies tightly against the body 1.
  • the thread storage chamber 11 must be designed in such a way that in the storage position the suction air flowing through it is so strong that it can grip the thread, but does not generate any eddies in the thread storage chamber 11.
  • the suction air must lie well on the side of the wall. This prevents the thread 2 to be stored from curling and being damaged or from breaking when pulled off.
  • Thread storage chambers 11 of a shape other than the one shown are also suitable, which allow a vortex-free flow with sufficient suction power.
  • the design of the mouth opening and the widening of the chamber cross section in relation to its length are decisive for a swirl-free flow through the thread storage chamber 11.
  • the thread storage chamber 11 is expanded too much, that is, if the angle between the tangent to the wall of the thread storage chamber 11 and the direction of flow is too large, the flow can no longer be against the wall and thus generates vortices that capture the thread 2 and in can negatively influence the manner described above.
  • the sieve surface 12 must ensure that the thread 2 is placed in an orderly manner on the sieve surface 12 and can be removed again without damage. If the screen surface 12 is not curved, as in the exemplary embodiment, but is curved, it is possible, if the screen surface does not necessarily enlarge the rotatable body 1, to store an even greater thread length without increasing the installation space of the device. Instead of the screw connection shown, the screen surface can of course also be fastened to the body 1 by clamping, gluing or other connections.
  • the described device works according to the following procedure:
  • the thread 2 to be stored is detected by the suction air flow acting at the end of the suction pipe 3 and sucked through the suction pipe 3 into the thread storage chamber 11, which is locked in the position according to FIG. 1.
  • the sucked thread 2 is deposited on the screen surface 12 of the thread storage chamber 11 and thereby increasingly reduces the effective suction surface.
  • the thread layer building up in front of the sieve surface 12 reduces the suction air flow in the suction pipe 3 and also gradually reduces the flow force that is required for sucking in further thread 2.
  • the amount of thread stored remains constant until the thread 2 is withdrawn from the suction pipe 3 and the thread storage chamber 11.
  • the withdrawal direction is opposite to the storage direction of the thread.
  • the rotatably mounted body 1, in which the thread storage chamber 11 is located is rotated such that the thread storage chamber 11 and the screen surface 12 are flowed through counter to the storage direction. Remaining thread residues and dirt 21 are removed from the screen surface 12 and the thread storage chamber 11.
  • the rotatably mounted body is not locked in this position, but is slowly moved through this position. If this procedure is sufficient for cleaning the screen surface, the device is simplified in that only two ball pressure pins 61 or two lockable positions according to FIGS. 1 and 2 are required.
  • Stubborn dirt can only be removed by locking the rotatably mounted body 1 in this position and remaining there until the screen surface 12 is cleaned.
  • the rotatably mounted body 1 is rotated into a position in which it separates the suction air flow applied to the vacuum line 4 from the suction pipe 3 until a renewed thread storage is to be carried out.
  • This method ensures in a simple manner that a thread end of a certain length can be stored and released again and that the thread storage chamber 11 is fully ready for use again after a short cleaning time. If the thread storage chamber 11 is not required, the suction air flow can be switched off in an energy-saving manner without additional devices being required.
