Definitions

  • the invention relates to a method and a device for air conditioning a spinning material located in a container, which is further processed on a spinning machine surrounded by a room climate.
  • US Pat. No. 3,073,106 discloses the air conditioning of slivers and drafting devices for drawing the slivers.
  • the air conditioning takes place in an air-conditioned housing mounted on the ring spinning machine.
  • the housing is divided into an upper and a lower section, which are each closed with doors.
  • the problem with such a device becomes clear. Due to the simultaneous air conditioning of a large number of fiber slivers and drafting systems, the air-conditioned room must be opened very often in order to replace the fiber slivers or to clean the drafting systems, as a result of which the optimal climate is disturbed. In addition, such doors are a hindrance to the increasingly important automation of the spinning process.
  • the fiber material which is stored in a container, is exposed to a climate which is independent of the room climate surrounding the spinning machine, there are advantages both in terms of the quality of the product to be produced and also in that Energy expenditure required for air conditioning.
  • the fluid volume to be air-conditioned, which surrounds the spinning material is kept very low.
  • air conditioning of the spun material is made possible with regard to an optimal climatic condition without disturbing influences of the indoor climate. Because only that Spun material and not the larger environment and the containers have to be air-conditioned, a very exact setting of the climate, which is optimal for further processing of the spinning material, is made possible.
  • spun material Any material that has a certain water absorption capacity can be considered as spun material. This enables the climate to influence running behavior and yarn quality.
  • the different climates differ in terms of their temperature and humidity.
  • Spun material that differs climatically from the optimal climate gradually assumes the surrounding optimal climate asymptotically depending on the time. This means that a certain amount of time is required for optimal air conditioning of a spinning material.
  • the processing speed becomes ever faster, it is therefore necessary for the spinning material to be processed to be exposed to the optimum climate in good time. A sufficient exchange of moisture and temperature is only possible if the optimal climate has been in contact with the spun material for a sufficiently long time.
  • the spinning material and fluid are in a state of equilibrium. If the fluid already has an optimal climatic value, it is important that it is kept essentially constant at this value so that the spun material can adjust to this value. This is preferably done by continuously exchanging the fluid, which gradually deviates from the optimal state, for a fluid which in turn has the optimal climate.
  • an optimally conditioned fluid flows through the container that contains the spinning material, the entire spinning material is gradually brought into the optimum state.
  • the fluid flows along the layers of material and then escapes the container.
  • the open material layers adopt the optimal state faster than the hidden material layers of the spinning material. If the spinning material is removed from the open layers for further processing, this spinning material is in the optimally air-conditioned state and, after removal, releases the next previously hidden layers of the spinning material. These new layers are in turn contacted by the optimally air-conditioned fluid and an equilibrium state is established between the spinning material and the fluid.
  • the fluid flows through the container in the removal direction of the spinning material, the fluid is advantageously discharged from the container. If the fluid flows through the container counter to the removal direction of the spinning material, there is the advantage that the optimally air-conditioned fluid acts on the spinning material that is next removed from the container. The fluid which comes into contact with the spun material removed next is thus not changed by the air conditioning of other layers of the spinning material which can be removed later.
  • the flow rate of the fluid is advantageously selected as a function of the removal speed of the spinning material from the container. This has the advantage that when the spinning material is removed from the container more quickly, the transition from the original climate of the spinning material to the optimal climate of the fluid takes place more quickly.
  • the described method can be carried out in particular by means of a device in which outlet openings of at least one air conditioning duct of an air conditioning system are arranged on the container in such a way that a conditioned fluid flowing from the outlet openings acts at least on the spun material to be removed next.
  • the spinning material is influenced in such a way that, when it is processed further after the air conditioning, it has an optimal climatic state for this further processing.
  • the fact that the outlet openings of the air-conditioning duct are directed directly onto the spinning material and are arranged in the immediate vicinity of the spinning material ensures that the spinning material is advantageously air-conditioned, with a small fluid volume to be generated or maintained in an optimally air-conditioned state .
  • the spinning material is always in an optimally air-conditioned environment.
  • This device works particularly effectively when the outlet openings of the air-conditioning duct are arranged in such a way that the air-conditioned fluid acts on the exposed layers of the spinning material in the container.
  • the spinning material to be processed next assumes an equilibrium moisture content corresponding to the conditioned fluid.
  • the container is closed by means of a cover in such a way that it prevents the fluid from escaping from the container without resistance, on the one hand the advantage is achieved that the fluid can act on the spun material for a long time without having to be renewed.
  • the cover ensures that flying and dirt parts from the surroundings of the spinning machine fall onto the uppermost layers of the spinning material and thus deteriorate the running behavior during further processing.
  • the conditioned fluid essentially extends to the volume between the uppermost layer of the spinning material and the cover of the container. This enables the fluid to be conditioned to be restricted to a small volume.
  • the cover is arranged on the container, there are advantages when transporting the container to the spinning machine.
  • the cover protects the spun material from contamination and from changes in the climate specific to the spinning material. It is also possible that the spun material is already prepared for removal from the container. If, for example, the spinning material is a sliver, it can be prepared apart from the spinning machine in that it is passed through the cover and an introduction into the spinning machine is facilitated.
  • the cover has openings for the removal of the spinning material and for the escape of the fluid, it is advantageously achieved that the fluid essentially passes through other openings gives way than the spinning git. In this way, a gentle removal of the spinning material from the container is achieved, since a fraying of the spinning material during removal from the container is avoided by the fluid flowing along.
  • the size of the openings is adjustable, on the one hand the fluid flow and on the other hand the gentle removal of the sliver or the threading of the sliver into the removal opening is made possible.
  • the regulation of the air flow makes it possible to set the renewal rate of the fluid.
  • the container can be connected to a central air-conditioning duct on the spinning machine, the total volume of the fluid to be air-conditioned on the spinning machine is reduced. All containers which result in the same spinning material or the same processing of the spinning material can be supplied from an air conditioning system. If the central air conditioning duct is arranged on a double-sided spinning machine, it supplies both sides of the spinning machine by connecting the containers on both sides of the spinning machine according to the division of the further processing points.
  • the container is a supply can for fiber sliver and the conditioned fluid flows through the supply can in its air spaces, the lower layers of the spun material are pre-conditioned in addition to the air conditioning of the uppermost layers of the spinning material.
  • the shape of the reference jug is not only limited to round jugs, but also applies to oval jugs, for example.
  • the air conditioning takes place in the removal direction of the sliver, it is advantageous if openings are provided in the can plate on which the sliver is stored, through which openings the fluid flows into the air spaces of the stored fiber band entry. With a tape delivery of about 3 cm / sec, the top 3 to 5 layers of the fiber tape are exposed to the conditioned fluid for at least 20 minutes. This is sufficient to air-condition the fiber material appropriately before it enters the spinning unit. The optimum moisture and temperature content of the fiber material can be maintained.
  • the container has a shape which tightly encloses the storage shape of the spinning material. It should be noted that at least the spinning material to be removed next from the container is stored in exposed positions in the container and the fluid can flow around it.
  • the method and the device are therefore suitable for all spinning materials in which the removal from the container takes place so slowly on the one hand that an air-conditioned fluid can act on the spinning material for a sufficiently long time and which can be exposed to the fluid with the largest possible surface area.
  • FIG. 1 shows one half of a double-sided OE rotor spinning machine 1, on which a dissolving device, a rotor and a winding device are shown as a schematic diagram.
  • a sliver 3 stored in a can 2 is drawn into this spinning machine.
  • the sliver 3 used as spinning material is deposited cycloidally in the can 2. This creates an air space 21 in the middle of the can 2, which is surrounded by the stored fiber material 31.
  • the cans 2 are placed on an air conditioning duct 4 in FIG. 1.
  • Recesses are provided in the bottom of the can and in the plate on which the fiber material 31 rests, through which a fluid flows.
  • the air conditioning duct 4 is penetrated by a fluid in the flow direction S. flows.
  • the fluid In terms of temperature and humidity, the fluid has an optimal climate for the further processing of the sliver 3.
  • the fluid sweeps along the sliver 3 in the air space 21, as a result of which there is an exchange of temperature and moisture between the sliver 3 and the fluid. This exchange takes place until the sliver 3 is in a state of equilibrium with regard to temperature and humidity with the fluid flowing through.
  • the sliver 3 there is thus a gradual adaptation of the sliver 3 to an optimal climatic state for the further processing of the respective sliver 3.
  • the adaptation to the optimal state takes place up to a degree of saturation, the better the longer the fluid acts on the sliver 3.
  • This method is therefore particularly suitable for use on spinning machines, on which the spinning material can be exposed to the influence of the conditioned fluid for a sufficiently long time.
  • the advantage of the invention is that the cans 2 can stand in any climate in a spinning room and the spun material is processed in an optimally air-conditioned state.
  • Another advantage results from the fact that the present invention can process different qualities of the spinning material on a spinning machine with several processing stations. Spun materials that are delivered to the processing site in different climatic conditions are subjected to different climates, which means that they have the same climatic condition at the time of processing. It is also possible with the present invention to produce different qualities on a spinning machine with several processing stations. In particular in spinning machines 1 with a plurality of spinning stations 11, spinning of the same type becomes the same goods produced different thread numbers. Different climatic conditions of the spun material are optimal for the individual thread numbers. With the present invention it is possible to generate different climatic conditions of the spinning material to be processed by supplying a spinning machine 1 with a plurality of mutually independent climatic channels 4.
  • FIG. 2 shows the device according to FIG. 1 in a preferred embodiment of the invention, in which the cans 2 are provided with a cover 5.
  • This has the advantage that the conditioned fluid introduced into the cans 2 does not escape without resistance. It is thereby ensured that the optimal climate, especially on the uppermost layers of the sliver 3 in the can 2, acts for a sufficiently long time so that the spun material which is processed next assumes the optimal climatic condition of the fluid.
  • the covers 5 are plastic hoods which are placed over the individual cans 2. Through an opening in the plastic hood, the fiber sliver 3 is guided outwards to the processing point on the spinning machine 1. The plastic hood prevents the inflated, conditioned fluid from escaping unhindered. An air-conditioned area, which may differ significantly from the room climate, spreads over the uppermost layers of the fiber slivers 3 in the can 2.
  • the conditioned fluid acts on the spun material for a considerably longer time, as a result of which there is a longer time available for the temperature and moisture exchange between the fluid and the fiber sliver.
  • the temperature and humidity level The exchange between spinning material and fluid is essentially asymptotic. This means that initially a very rapid adaptation of the climatic condition of the spinning material to the approximate climatic condition of the fluid takes place. With increasing time, the adaptation to the actual climatic condition of the spinning material to the fluid becomes ever slower.
  • Fig. 3 shows a spinning machine 1 with a central air duct 4 '.
  • the central air conditioning duct 4 ' supplies both sides of the double-sided spinning machine with the air-conditioned fluid. Both the construction effort and the total amount of the conditioned fluid used on a spinning machine 1 are reduced compared to the exemplary embodiments in FIGS. 1 and 2, since the total volume of the line system through which the conditioned fluid is conveyed is reduced.
  • the cans 2 stand on a platform 6 provided with outlet openings 41, through which the fluid which is branched off from the central air conditioning duct 4 'is supplied to the cans 2 in lines 60 and flow through them.
  • the platform 6 is arranged at ground level in the embodiment of FIG. 3.
  • Fig. 4 shows a spinning machine 1 with central air conditioning channels 4 'and 4 ⁇ .
  • a mobile platform 61 is coupled to the air conditioning duct 4 '.
  • a cover 51 is arranged on the mobile platform 61 net, which in this embodiment extends over two cans 2.
  • the air-conditioned fluid flows from the central air-conditioning duct 4 'through a coupling 62 into the mobile platform 61 and from there into the cans 2.
  • the coupling 62 allows the mobile platform 61 to be flanged onto the air-conditioning duct 4' after changing the cans.
  • the cans 2 are delivered to the spinning station on the platform 61 and connected to the air conditioning duct 4 '.
  • On the clutch 62 a closure is advantageously arranged, which closes the air conditioning duct 4 'at the location of the clutch 62 as soon as the platform 61 is removed. This prevents the conditioned air from escaping into the spinning room.
  • a two-part, central air conditioning duct 4 ', 4 ⁇ is shown. This ensures that the spinning machine 1 can be supplied with two different climates. This enables optimal air conditioning of different qualities of spinning materials and / or products that are processed or produced on the machine.
  • the cover 51 prevents the fluid from escaping unhindered. It therefore also acts on the uppermost layers of the sliver 3 in the can 2 for a longer time.
  • the conditioned fluid flows out of the cover 51 either through the open underside or through exhaust air openings which are arranged on the top of the cover 51.
  • the cover 51 includes openings on the top for removing the sliver 3 from the can 2.
  • the platform 61 is either manually transported to the respective coupling point 62 of the central or a decentralized air conditioning duct 4 ', or it is automatically driven, for example, in the Type of driverless transport system assigned to its place.
  • FIG. 5 shows an air conditioning of the spun material against the removal direction.
  • the air conditioning duct 4 is arranged above the can 2 on the spinning machine 1.
  • the climate outlet openings 41 are arranged on the air conditioning duct 4 in such a way that the outflowing climate acts on the uppermost layers of the fiber sliver 3.
  • the cover 52 like the cover 51 in FIG. 4, contains openings for removing the sliver 3 and, in an advantageous embodiment, openings for regulating the climate exchange below the cover 52.
  • the cover 52 is on the air-conditioning duct 4 or the spinning machine 1 arranged stationary.
  • an embodiment is also advantageous in which the cover 52 is arranged on a can 2 and is coupled to the outlet opening 41 of the air conditioning duct 4.
  • the embodiment according to FIG. 6 shows spinning cans 2 through which the conditioned fluid flows in the countercurrent principle.
  • the air-conditioned fluid which flows out of the air conditioning duct 4 first acts on the upper layers of the sliver 3 in the can 2 and flows through the air space 21 which is formed in the middle of the can 2.
  • the fluid is passed through the air space 21 and through the bottom of the can 2 into a platform 6, through which it flows outwards.
  • an adjustable cover of the outflow openings in the pedestal 6 is advantageous, by which the flow rate can be influenced.
  • the underside of the cover 50 advantageously closes tightly with the circumference of the cans 2, for example with rubber lips. This ensures the intended direction of flow of the fluid through the air flow 21.
  • the cans 2 are replaced by opening a side surface of the cover 50.
  • the cover 50 is designed such that the space between the can 2 and the point of further processing, in this case a opening roller 11, can be air-conditioned. This ensures that the sliver 3 is exposed to the optimal climate until immediately before it is processed, without the supplied optimal climate being sucked into the spinning machine 1 by the negative pressure prevailing in the spinning machine 1 and thus air conditioning the spinning material insufficiently.
  • FIG. 7 shows a front view of a spinning machine 1 with spinning stations 11 arranged side by side.
  • Each spinning station is assigned a can 2, which is arranged on an air conditioning duct 4.
  • the cans 2 covered with a cover 52 are flowed through independently of one another by an air-conditioned fluid.
  • Each can 2 is individually covered by a cover 52.
  • the cover 52 is advantageously also arranged during the transport of the can 2 on the can 2, as a result of which a change in the climate of the fiber sliver 3 is delayed in contrast to an open storage.
  • the sliver is already subjected to an air-conditioned fluid and thus extends the time in which the optimally air-conditioned fluid can act on the sliver 3 as a whole becomes. If the can 2 is covered during transport from the warehouse to the processing station, the stressed climate lasts longer ger in the can 2. In addition, the first processed fiber sliver 3 is supplied to the processing site in an already optimally conditioned condition.
  • FIG. 8 shows the cover 52 in a top view.
  • An opening 53 is arranged centrally on the cover 52, through which the sliver is removed from the can.
  • an elongated slot 54 leads in the direction of the opening 53.
  • the slot 54 facilitates removal of the fiber sliver 3 from the can 2 and insertion of the fiber sliver 3 into the opening 53.
  • the sliver 3 is removed from the can 2 and threaded into the slot 54.
  • the slot 54 is closed. This is done, for example, by rotating a disk that is mounted centrally to the opening 53. This ensures that the sliver 3 is not automatically threaded during removal from the can 2 for further processing and is damaged thereby.
  • outflow openings 55 are arranged on the surface of the cover 52, through which the fluid introduced into the can 2 flows out.
  • a change in the cross section of the openings 55 influences the flow velocity and thus the rate of renewal of the fluid. This takes place as a function of the removal speed of the sliver and the difference between the optimal climate and the initial climate of the sliver 3.
  • the outflow openings 55 can also be closed by rotating a disk arranged below the cover 52. 8, the round outflow openings 55 are shown approximately half closed.
  • the outflow openings 55 can of course also be arranged laterally from the cover 52.
