    Device for cleaning an open-end spinning turbine comprises a bell (24) which can be fitted to a container (7) holding the spinning rotor (9) and which is mounted on an arm (26) operated by a jack (27). Said bell (24) bears a piston (30) of which the fronttapered end probesthe bottom of the throat for uniting the fibres in the rotor (9) when the bell (24) is joined to the container (17). The procedure consists in letting a certain quantity of fibres enter after breakage of the yarn so as to form a ring of fibres in the rotor and then to halt this ring by means of the piston (30) until the rotor (9) stops, while the scraping or rubbing of the ring of fibres enables the impurities stuck in the area of the throat for uniting the fibres to be detached.

    The invention relates to the textile industry and relates to multiple spinning machines, namely the cleaning of their spinning chambers.
    A known method of cleaning the spinning chamber 5 of the spinless spinning machine is to disconnect the spinning chamber from the drive to rotate it when the spinning process is terminated in it, to form a rotating fiber ring on the collecting surface of the chamber and to separate the weed impurities from the chamber with their subsequent withdrawal together with the fiber ring from the chamber by means of a suction 15 air flow [1
    It is also known a device for cleaning the spinning chamber of a spinless spinning machine, comprising a head 20 mounted on a carriage with a funnel communicating with its hole with an air suction system and mounted on the head by means of a lever with the possibility of connecting with the end face to the stationary housing 25 of the drive spinning chamber mounted with the possibility of removal from drive its rotation, and a node for supplying fibers to the camera, connected to the sensor of breakage of yarn and placed on 30 of its cover, pivotally mounted on the camera body with POSSIBILITY retraction from it [1].
    The disadvantages of the known technical solutions are the low cleaning efficiency and the possibility of damage to the assembly surface of the spinning chamber with a cleaning agent.
    The purpose of the invention is to increase the cleaning efficiency without damaging the inner surface of the chamber.
    This goal is achieved by the fact that in the method of cleaning the spinning chamber of a non-spinning spinning machine, which consists in disconnecting the spinning chamber from the drive of its rotation when the spinning process is terminated in it> forming a rotating fiber ring on the collecting surface of the chamber and separating the weed impurities from the chamber with their subsequent withdrawal together with a fiber ring from the chamber by means of a suction air stream, a fiber ring is formed in the chamber by feeding fibers into it after the spinning process in the chamber is stopped e, a separation of trash from the chamber is effected by pressing the fiber ring to its modular surface.
    holding it against rotation using. rod to a complete stop of the camera.
    Moreover, a device for cleaning the spinning chamber of a non-spinning spinning machine, comprising a head mounted on the carriage with a funnel communicating with its hole to the air suction system and mounted on the head by means of a lever with the ability to connect the end to the stationary housing of the drive spinning chamber, which is rotatable away from the drive a unit for supplying fibers to the chamber associated with the sensor of breakage of yarn and placed on its lid pivotally mounted on the camera body the outlet from it contains a rod with a conical head at the end, while a hole is made in the funnel wall and a rod is installed in it with the possibility of axial movement by means of a power cylinder with an engine and placement of the conical head of the rod on the assembly surface of the chamber, and the fiber supply unit is connected. with a yarn break sensor via a time relay.
    In FIG. 1 shows a spinning position of a multiple-spinning spinning machine, operating position -, in FIG. 2 - the same, the cleaning position of the spinning chamber; in FIG. 3 is a circuit diagram for controlling the operation of the fiber supply unit of the machine.
    The spinning place of the multiple-spinning spinning machine comprises a cover 1 mounted on the bed 2 of the machine, on the drive shaft 3 and by means of a hinge 4 connected to the housing 5 of the spinning chamber 6, placed in the hole 7 of the bed 2 with the possibility of movement relative to it; In the lid 1 there is a node 8 for supplying fibers 9 to the spinning chamber, connected by an electromagnet 10 with a breakage sensor 11 of yarn installed in the lid 1 at the outlet of the channel 12 for outputting yarn. The electromagnet 10 is connected to the clutch 13 on the shaft of the wheel 14 of the worm pair, the worm 15 of which is mounted on the shaft 3.
    In the cover 1, a hollow fiber separator 16 connected to the channel 12 is installed, which is located coaxially with the spinning chamber b, the shaft 1.7 of which is mounted by bearings in the cylindrical part 18 of the housing 5. The cover 1 is fixed during the operation of the spinning chamber by a spring-loaded latch 19, fixed with a protrusion 20 on the bed 2.
    On the carriage mounted on rails with the possibility of moving along the machine (not shown), the head of the device for cleaning the spinning chamber is mounted, having a funnel 21 communicating with its openings 22 using pipelines 23 with an air suction system (not shown). Pipelines 23 are levers mounted on an axis 24 mounted on a device carriage. By means of levers, the funnel has the ability to be connected by an end face to the fixed body 5 (Fig. 2).
    A hole is made in the wall of the funnel 21, in which a rod 25 is installed with a conical head 26 at one end and connected to the other end with a piston 27, a spring-loaded spring 28, located between the thrust disc 29 at the end of the piston and the force cylinder 30 having an engine, providing fluid to the cylinder.
    The yarn breakage sensor 11 has a permanent magnet 31, which controls the operation of the relay 32 and the time relay 33, which controls the operation of the switch 34, connected in series to the electromagnet 10, which controls the operation of the clutch 13 (Fig. 3).
    To supply the funnel with its end to the housing 5, a traction element 35 is provided.
    In the process of operation of the spinning machine, the spinning chamber forms yarn from it entering the rotationally driven drive belt 36 and forms yarn in it, which, through the hollow separator 15 and channel 12, is withdrawn from the chamber and wound onto the package.
    Upon termination of the spinning process due to a break in the yarn, a sensor 11 is activated, which sends a signal to turn off the fiber supply unit. Relay 33 after a specified period of time gives a command to operate the electromagnet 10, which disables the drive unit fiber supply.
    In this period of time after the termination of the spinning process, fibers are fed into the rotating spinning chamber and a rotating fiber ring is formed from them on its prefabricated surface. After turning off the fiber supply unit, the spinning chamber is disconnected from its drive when the cover 1 is opened, it is tilted and the housing 5 is shifted together with the shaft 16 in the hole of the bed 2, which leads to the removal of the shaft 16 from the belt 36. Next, weed impurities are separated from the camera by pressing the rotary - * * inertia of the fibrous ring inertia to its prefabricated surface with the help of the rod 25, moved by the piston of the power cylinder, and holding this layer from rotation until the camera stops completely. Then, through the pipelines 23 by means of suction air flows weed impurities together s
    with a fiber ring from the chamber. The gap between the ends of the rod head and the assembly surface of the chamber during the separation of weed impurities from it is approximately 1 mm.
    After the spinning chamber is stopped, the piston with the rod is loaded into the idle position.
    The proposed cleaning method and device for its implementation can improve the cleaning efficiency of the spinning chamber without damaging its collection surface, prevent the possibility of accumulation of weed impurities on it, and eliminate the need for special means for rotating the spinning chamber.
