Definitions

  • the invention relates to a textile machine with several spinning devices having an inlet opening for a sliver to be spun, in particular air spinning devices and a spinning hood for a spinning device of a textile machine.
  • Textile machines of the type mentioned have a plurality of spinning devices for the production of a yarn, to which a fiber material is supplied, with the spinning device producing a yarn from the fiber material supplied to the spinning device, which yarn leaves the spinning device via an outlet, where it is with the help a winding device is wound onto a tube.
  • the spinning devices of generic textile machines can be designed, for example, as air-jet spinning machines, in which a yarn is produced from a strand-like fiber material (e.g. a sliver) with the aid of a vortex air flow generated by air nozzles within a vortex chamber.
  • a strand-like fiber material is conveyed in the direction of an inlet opening of a spinneret with the aid of a delivery device, which is preferably formed by a pair of output rollers of a drafting device upstream of the spinneret in the spinning direction, and is sucked in or sucked in by this by vacuum.
  • the fiber material finally reaches the interior of the spinneret and there into the area of an inlet opening of a spindle-shaped yarn-forming element.
  • the fiber material is fed into the inlet opening of the spinning device, in particular an air-jet spinning machine, without contamination.
  • Contaminants in the vicinity of the inlet opening such as, for example, dirt particles, paraffins, oils or the like, can be conveyed unhindered into the inlet opening with the fiber material and have a negative effect on the yarn quality.
  • the invention is based on the object of providing a textile machine with several spinning devices having an inlet opening for a sliver to be spun, in which a supply of contaminants into the inlet opening is largely prevented.
  • the invention solves the problem by a textile machine with the features of claim 1 and by a spinning hood for a spinning device of a textile machine with the features of claim 6.
  • Advantageous developments of the textile machine are in the dependent claims 2 to 5, advantageous developments of the spinning hood in the dependent Claims 7 and 8 specified.
  • the textile machine according to the invention is characterized by a spinning hood which delimits a spinning space around the inlet opening from the environment.
  • the spinning hood is a cover enclosing an area around the inlet opening, which can be detachably arranged on the spinning device in the area of the inlet opening so that with the components of the spinning device adjoining the spinning hood, a space delimited from the surroundings of the spinning device with a Access opening for the sliver to be fed to the inlet opening of the spinning device is created.
  • the spinning hood delimits the surroundings of the spinning device from the spinning space and thus prevents the penetration of contaminants from the surroundings as well as interference with the spinning space.
  • the spinning hood can also prevent the spread of fires if it is made of a refractory material for this purpose.
  • the spinning hood can, for example, be designed as a box-shaped housing having an opening, the contour of the edge surrounding the opening being adapted to the contour of the spinning device and its components in their installation position on the spinning device in order to ensure a circumferential contact with the spinning device.
  • the spinning hood can be secured in position on the spinning device in any way, for example by means of suitable fastening screws. According to an advantageous development of the invention, however, it is provided that the spinning hood can be locked in an operating position on the spinning device. Fixing the spinning hood on the spinning device ensures its particularly good alignment with respect to the inlet opening. In addition, additional fastening elements on the spinning device can be dispensed with, so that no adaptation of the spinning device is necessary in order to be able to use the spinning hood.
  • the design of the releasable locking of the spinning hood on the spinning device is basically freely selectable. According to a particularly advantageous embodiment of the invention, however, it is provided that the spinning hood has a locking element which is adjustable, in particular pivotable, with respect to a hood base body between a locking position and a removal position and which is in engagement with the spinning device in the locking position.
  • the locking element is between a locking position in which it locks the spinning hood on the spinning device and a removal position in which the locking element is out of engagement with the spinning device and the spinning hood is released from the spinning device or positioned on it can, adjustable.
  • the locking element brings about a particularly reliable, positionally secure arrangement of the spinning hood on the spinning device, the locking element for this purpose preferably being designed in such a way that in the locking position it produces a non-positive and / or positive connection between the spinning hood and the spinning device.
  • the use of tools for fastening the spinning hood to the spinning device can thus be dispensed with.
  • the locking element can also be designed in such a way that in the locking position it forms a housing section of the spinning hood that delimits the spinning chamber. This makes it possible to dispense with separate locking elements on the spinning hood.
  • access to the spinning chamber is provided, which enables any maintenance and inspection work that may be required within the spinning chamber without complete dismantling of the spinning hood.
  • the locking element can in principle be designed for connection to any components of the spinning device. According to an advantageous further development of the invention, however, it is provided that the locking element is designed to fix the spinning hood on a drafting system of the spinning device, in particular a supporting frame of a drafting system.
  • Fixing the spinning hood to the drafting system, in particular the support frame of the drafting system, ensures particularly good alignment of the spinning hood with respect to the inlet opening and the sliver fed from the drafting system. Malfunctions due to an incorrectly aligned spinning hood can thus be avoided particularly reliably.
  • the locking element which is advantageously provided, can be secured in position on the hood base body in the locking position in any way. According to an advantageous embodiment of the invention, however, it is provided that the locking element is releasably lockable on the hood base body, in particular has a detent body that can be releasably engaged with a locking mark on the hood base body in the locking position.
  • the locking element is locked in the locking position on the hood base body, the locking being implemented particularly advantageously via a connection by means of a locking body engaging a locking mark in the locking position.
  • These can be spring-loaded or elastically displaceable latching bodies arranged on the locking element, which in the locking position engage in corresponding latching marks on the hood base body. Unlocking can take place by directly actuating the locking body.
  • the connection between the latching body and the latching mark can be designed in such a way that, when a defined force is applied to the locking element, the latching bodies are moved out of the latching marks.
  • the spinning hood according to the invention for a spinning device of a textile machine is characterized by a hood base body and a locking element which is adjustable between a locking position and a removal position, in particular a pivotable locking element, which is designed such that the spinning hood is in locked in the locking position on the spinning device.
  • the hood base body and the locking element form a closed spinning hood with an access opening for the sliver to be fed to the entry opening of the spinning device.
  • the installation position of the spinning hood is adjacent to the spinning device with the components of the spinning device adjoining the spinning hood, a spinning space around the inlet opening largely relative to the environment, so that the ingress of contaminants into the inlet opening is largely prevented.
  • the locking element comes into engagement with the spinning device, for example a housing section, in such a way that the spinning hood is non-positively and / or positively locked on the spinning device, so that additional fastening elements can be dispensed with.
  • the spinning device for example a housing section
  • the hood base body and the locking element are particularly advantageously formed from a fireproof material, as a result of which the spread of fires in the area of the inlet opening can be prevented.
  • connection between the locking element and the hood base body can in principle be freely selected. According to a development of the invention, however, it is provided that the locking element is arranged on the base body in such a way that an access opening to a hood interior is released in the removal position. This refinement makes it possible to inspect the spinning chamber and, if necessary, to carry out maintenance work without removing the spinning hood.
  • the locking element can be secured in position in the locking position in any way. According to a further development of the invention, however, it is provided that the locking element can be locked in the locking position on the hood base body, in particular has a detent body which can be releasably engaged with a locking mark on the hood base body in the locking position.
  • an open position for the locking element is preferably provided between the locking position and the removal position, between which the locking element can be pivoted.
  • the spinning hood has a swivel joint for this purpose.
  • the open position enables easy release from the locked position by applying pressure at a suitable point on the locking element, the locking element being easily pivotable in such a way that an upper edge section is accessible and open as a grip element for moving the locking element out of the open position the removal position can function.
  • the swivel joint is particularly preferably formed from a latching recess and a complementary latching bolt which can be brought into engagement with the latching recess, the latching recess being rotatable about the latching bolt in the engaged state.
  • Such a swivel joint can be implemented in a structurally simple and inexpensive manner.
  • the latching recess can be arranged either on the locking element or on the hood base body, the latching bolt being arranged accordingly on the other component.
  • the configuration of the invention represents a particularly simple, inexpensive and reliable way of releasably locking the locking element on the hood base body.
  • the actuating force required for unlocking can be determined in a particularly simple manner by selecting the preferably provided locking body. This can be generated directly on the latching body or by a sufficient actuation pressure applied to the locking element at a suitable point, as a result of which the locking element is preferably pivoted into the unlocked position.
  • a spinning device 11 is shown with a spinning unit designed as an air spinning unit 1 of a textile machine, not shown here.
  • a strand-like fiber material (not shown here) is conveyed in the direction of an inlet opening of a spinning nozzle with the aid of an output roller pair of a drafting system 3 of the spinning device 11 upstream of a spinning nozzle of the air spinning unit 1 in the spinning direction and is sucked in or sucked in by this by negative pressure.
  • a spinning hood 2 is the Spinning device 11 arranged in an operating position.
  • the spinning hood 2 delimits a spinning space around the inlet opening from the surroundings, for this purpose it rests circumferentially on the drafting system 3 and the air-jet spinning unit 1 without hindering the feed of the sliver from the drafting system 3 into the inlet opening.
  • the spinning hood 2 shown in a removal position has a hood base 4 and a flap-shaped locking element 5 which is pivotably connected to the hood base 4.
  • the locking element 5 In the operating position of the spinning hood 2, the locking element 5 is arranged in its locking position, in which it forms a closed hood together with the hood base 4.
  • In the locking position there are locking elements 6a, 6b on the locking element 5 with corresponding sections on the air-jet spinning unit 1 and the drafting system 3 in engagement and thus lock the spinning hood 2 in the operating position on the air-jet spinning unit 1, a bulge 9 on the locking element 5 being an unobstructed one Supply of the sliver into the air-jet spinning unit 1 guaranteed.
  • the locking element 5 is in its Fig. 2 locking position shown in its in Fig. 3
  • the removal position shown relative to the hood base 4 can be brought via an intermediate open position.
  • the locking elements 6a, 6b are out of engagement with the spinning device 11, so that the spinning hood 2 can be dismantled and assembled.
  • the locking element 5 enables access to the spinning chamber, via which maintenance and inspection work can be carried out.
  • the locking element 5 is still pivotably coupled to the hood base 4 via a swivel joint.
  • the swivel joint is formed by a semicircular latching recess 12 and a complementary, not visible, latching bolt, the latching recess 12, as in FIG Figure 3 shown, protruding laterally on the locking element 5 in the direction of the hood base 4 and the associated locking bolt are arranged on a corresponding inner side of the hood base 4.
