Definitions

  • the invention relates to a method and a spinning machine according to The preamble of claims 1 and 4.
  • From DE 31 51 063 A1 is a spinning machine with a pneumatic Feeding of fiber flakes, here a multi-chamber mixer from a blow room known.
  • the mixer has six filling chutes in a row on, which are connected to a transport channel through which the fibers in Direction to the filling shafts are conveyed by air.
  • the chambers are separated from each other by walls. In the area of the upper end of this Air outlet openings are provided on the walls, which are those of the fibers separated transport air through the remaining chambers from the Machine leads out.
  • Each of the filling chutes is at its upper end through a butterfly valve closable, the rest of the channel in its open position closes.
  • the fibers are specifically introduced into a shaft when the level in a shaft has dropped. After a certain one The flap becomes the height determined by a photocell closed again and the fiber stream fed to another filling shaft.
  • the disadvantage of this system is that it requires complex control is required to control the flaps. Since the flaps against the Transport air and fiber stream must be moved to keep the fiber stream in Redirecting the desired filling shaft is a robust design of the Flaps, as well as the control mechanism required.
  • EP 0 731 194 A2 describes an exhaust air flap of a filling shaft for a Carding machine or a similar memory known to operate with fiber flakes is supplied from a pneumatic flock transport system.
  • the shaft, or the storage unit separates the flakes from the transport air flow, which is the exhaust air is forwarded.
  • a valve which includes a flap that under the Dead weight assumes a predetermined rest position when there is no air through the valve flows.
  • EP 0 485 014 A1 shows a multi-chamber mixer which is in one of the outward-facing side walls has screen surfaces. Fiber flakes are transported together with the transport air via a transport channel into the promoted upper area of the filling shafts.
  • the entrance of the individual Filling chutes are arranged higher from filling chute to filling chute, whereby an even distribution of the fiber flakes among the individual, successively arranged chambers is to be effected.
  • About in the middle The height of the chambers is an exhaust air duct on the outside of the filling shafts arranged.
  • Each of the individual chambers is connected to the Exhaust duct connected.
  • the corresponding one Chamber does not continue to be supplied with fiber flakes because the transport air along with the fiber flakes the way across the chambers with lower fill level and thus free screen area in the exhaust air duct.
  • the object of the present invention is therefore that shown Avoid disadvantages of the prior art and be structurally simple and without complex control technology or adjustment work Device for uniform feeding of filling shafts in To create spinning machines.
  • the object is achieved by a method for filling an several chambers divided flake storage, in particular one Multi-chamber mixer or the like, solved with fiber flakes, fiber flakes fed to the chambers by means of a pneumatic transport air flow will.
  • the level in the individual chambers is essentially kept at the same level by adding a valve and a air-permeable surface are assigned, the valve when sinking the level on the air-permeable surface to increase the level opens in this chamber and a separation of transport air flow and Fiber flakes take place on the air-permeable surface of this chamber.
  • This Chamber is fed more fiber flakes that at The level on the air-permeable surface rises to one Reducing the level in this chamber closes the valve again, and this chamber gets fewer fiber flakes.
  • the system steers on simple way the level of the fiber flakes in a chamber and adjusts their fill level to the fill level of the neighboring chambers.
  • the process works particularly simply when the valve is through the changed air pressure in the individual chamber, which is caused by the change of the level in the chamber is caused to open independently or is closed.
  • the valve and the air-permeable surface can in the Chamber must be arranged, but at least in an active connection with stand in the chamber and thus be assigned to it.
  • a self-adjusting valve has the opposite to a driven valve Advantage that the valve closes and opens without the action of an actuator Depends on the fill level in the chamber. Such a valve responds the operating pressure or the air flow. These parameters need to be change as a function of fill level.
  • the invention also works with one driven valve very well.
  • the valve remains fully open as long as the air flow openings between the Mixing chamber and the air discharge unit are not (partially) covered. At the same time there is only a small difference between the pressure in the Mixing chamber and the pressure downstream of the valve. Both transport air as flakes also flow into the mixing chamber.
  • the fill levels are balanced among the Chambers instead as the air / flake flow the way with the minimum Seeking resistance, that is the mixing chamber with the largest uncovered Flow area and with the lowest filling level. In every mixing chamber the filling level oscillates within a through the flow area (sieve area) defined bandwidth up and down.
  • the speed of the upward movement depends not only on the filling level in your own Mixing chamber, but also from the filling levels of all other mixing chambers from. If all chambers have the same filling level, they all become the same replenished quickly. If a chamber has a particularly low fill level it is filled particularly quickly.
  • a generic spinning machine with the features of claim 4 causes in the manner according to the invention that the individual chambers, especially in a multi-chamber mixer, a card, card or one Cleaners are filled essentially uniformly. This will do so causes an exhaust unit to be assigned a valve flap. Due to the Pressure ratios in the chamber assigned to it changes Exhaust air flow in the corresponding chamber. The amount of in the chamber supplied fibers depends on the extent to which the screen surface of the chamber is open or closed. If the sieve surface is open, the Transport air from this chamber and it takes place on the air-permeable Surface, which is in particular a sieve surface, which is assigned to this chamber a separation of transport air and fiber flakes takes place. The severed Fiber flakes remain in the chamber and increase the Level of this chamber.
  • the transport air is through the open valve discharged as exhaust air. If the screen surface is closed, the Transport air is not routed through the chamber and the valve into the exhaust air duct. This prevents the transport air flow from being separated from the fiber flakes done and fiber flakes are therefore not in the appropriate chamber introduced.
  • the valve is closed in this state. Valve and air-permeable surface can be arranged in the chamber, they must but are at least in operative connection with the chamber.
  • the device according to the invention can be designed in a very simple manner and is therefore very easy to maintain. After the valve is not in the immediate area of the fiber flakes is soiled of the valve due to fiber flakes not possible. Special maintenance of the Valve due to contamination is therefore not necessary.
  • the exhaust air duct is advantageously common to several chambers assigned, creating a simple construction of the spinning machine is possible.
  • valve or the valve flap designed such that the amount of Exhaust air from a chamber depending on a flake level in the chamber independently changed, so is an extremely inexpensive training Invention enables.
  • valve flap is advantageously designed in such a way that, despite closed state releases a small amount of exhaust air. This will make one quick control of the valve flap causes the existing Exhaust air flow only needs to be increased in pressure to the To move the valve flap to an open position.
  • the valve flap is thus can be controlled faster than if an exhaust air flow is only in the range of Valve flap must be fed, or a standing air column only in Movement must be set.
  • valve flap by means of a Pivot bearing is rotatably mounted. Is the pivot bearing arranged so that the Valve flap generates a torque in its rest position due to its own weight, so that it is essentially closed, so there are no additional ones Components, such as springs, are required to make the valve flap independent to bring it into a closed position.
  • the valve flap is advantageously bent along its axis of rotation, so that it has two wing-like sections. It is also used in the closed Condition causes a certain flow of exhaust air through the valve.
  • the Sections of different sizes so is a balanced flow through the Valve allows.
  • the smaller section can be for one Stop that defines the maximum opening of the larger section, be provided. It is also possible that the smaller section is such is dimensioned that a flow takes place in the closed state.
  • at least one of the sections, in particular that of the exhaust air flow releasing section is designed trapezoidal. This makes fewer Flow losses to be expected when flowing through the valve.
  • the unit is attached to the chamber in a modular manner. So that's it for example possible with a multi-chamber mixer, the identical unit accordingly the required number of chambers in the multi-chamber mixer to grow. It is also possible with the modules that they are for assembly prepared and equipped with the appropriate valves and in be attached to the chamber in this condition. Are the modules on the Side wall of a chamber and the neighboring modular unit arranged, so connecting pieces in the exhaust air ducts are to be avoided, which additionally brings about the simplicity of the construction. To one To achieve correct functioning of the unit are the modules of two Adjacent chambers only in the area of the exhaust air duct connected with each other.
  • the calming rooms of two neighboring modules are separated from each other by a partition, so that the on Exhaust air flows or overpressures in the valve flaps neighboring chambers does not act on the valve of the neighboring chamber. This would cause the chambers to be filled incorrectly.
  • the calming space is from the outside a door is accessible. It is possible to use the screen surface and the Clean the relaxation room if necessary. Whether a cleaning is possible through an inspection window arranged in the door be assessed. Only when it has been determined by the visual inspection that Cleaning work is required, then the door must be opened and the To interrupt the flow process in the chamber or through the open Influence door.
  • valve flap is arranged in the upper area of the module.
  • a particularly great advantage of the invention is that one essentially identical exhaust unit is arranged on each side of a chamber. In order to is a uniform distribution of the width of the chamber Causes flakes of fiber. The individual chamber is thus at the maximum with Fillable fiber flakes.
  • Figure 1 shows a multi-chamber mixer 1, which the simplicity of Representation because of only four chambers. It goes without saying also multi-chamber mixer with more than four chambers for the invention applicable.
  • the multi-chamber mixer 1 fiber flakes 6 are on the Feed 3 fed to the individual chambers 2a, 2b, 2c and 2d.
