Definitions

  • the invention relates to a textile machine in the field of spinning preparation.
  • Such textile machines serve to separate fiber material (fiber tufts) coming from an upstream textile machine, such as a bale opener or heavy-part separator, which is intended to separate foreign material from the fiber material detached by the bale opener, which could cause damage to the downstream textile machine possibly with other foreign material) from that foreign material and to open the fiber tufts and to transport them to a downstream textile machine such as a mixer.
  • an upstream textile machine such as a bale opener or heavy-part separator
  • EP 2 554 726 B1 discloses an opener with a grate to separate foreign material in the form of shells and dirt from a fibrous material to be opened. It is therefore in the professional understanding of a cleaner.
  • This cleaner includes a feeder.
  • the feeder divides the incoming fiber-air flow so that both partial flows meet the first opening roller at a relatively small distance from the center of a first opening roller. Due to its rotation and the presence of guide elements along the outer circumference of this opening roller, the first opening roller transports the incoming fiber material outwards from these impingement points in mutually opposite directions along its axis of rotation to its two ends. The fiber material is then transferred to a respective opposite end of a second opening roller.
  • the second opening roller transports due to its rotation and in turn, guide elements present along the outer circumference of this opening roller guide the fiber material transferred from the first opening roller from its ends inwards towards its center in two mutually facing directions along its axis of rotation.
  • the fiber material that has been brought together in this way is then delivered via an outlet to a downstream textile machine.
  • a grate with a cellular wheel sluice arranged underneath is arranged below each opening roller in order to separate the foreign material that has been separated out.
  • the disadvantage of this cleaner is, firstly, that two transfer points are required between the pair of opening rollers, which complicates the structure and makes it expensive. Secondly, the division into two partial streams requires a divider, which further increases the cost of construction.
  • the object of the invention is to counteract the aforementioned disadvantages. This object is solved by the subject matter of the independent claims. Advantageous developments are specified in the dependent claims.
  • a device is provided on or in a textile machine. i.e. this device can be integrated into or attached to a textile machine as part of the latter.
  • the device has a plurality of cleaning sections, each with an associated opening roller.
  • Each cleaning section is designed so that when the associated opening roller rotates in a predetermined direction, fiber material is conveyed in a corresponding transport direction along the axis of rotation of the associated opening roller, thereby separating foreign materials.
  • the device includes an associated transfer section.
  • Each transfer section is designed so that the fiber material conveyed by an opening roller is transferred at one end of one opening roller to an opposite end of the other opening roller, seen transversely to the direction of transport, i.e.
  • the device also has an inlet which is arranged to convey incoming fiber material to an end of a first opening roller which is remote from the associated transfer section and on which only one opening roller is arranged directly adjacent. In this way, the fibre-air flow from an upstream textile machine such as a bale opener safely reaches the front end of the first opening roller in the cleaning direction. Furthermore, the device has an outlet which is arranged to transport fiber material away from an end of a last opening roller which is remote from the associated transfer section and on which only one opening roller is also arranged directly adjacent. Thus arrives the cleaned Fibrous material after passing through all opening rollers out of the device again.
  • the device according to the invention results in the fiber material covering at least the same cleaning distance as the cleaner disclosed in EP 2 554 726 B1, which means that the cleaning performance remains at least the same, but certainly over the entire operating time. Since there is only one transfer section between two directly adjacent opening rollers, the number of parts in the device is reduced and with it the costs and the structural design. Moreover, there is no need to provide a section for generating the partition air cushion, with the same advantages. In addition, the full volume flow can be used to transfer the material.
  • each cleaning section has a fiber guide section designed to guide the fibers along the axis of rotation of the associated opening roller and to release foreign materials from the transport path along the associated opening roller. This serves to prevent a material jam, which benefits operational safety.
  • At least one guide section can have a guide section, which is arranged at a distance along an outer peripheral surface of the associated opening roller and/or is designed such that the fiber material is pressed against the guide section and open due to the rotation of the associated opening roller and the centrifugal force acting on the fiber material - is deflected and/or intercepted in the corresponding transport direction due to the design of the guide section. This is for safety Transporting the material to be cleaned along the respective opening roller.
  • the guide section can have ribs.
  • the ribs each have a wall directed counter to the transport direction of the respective opening roller, which extends at least in sections in the direction of the opening roller and, viewed transversely to the corresponding transport direction, encloses an acute or right angle with the transport direction.
  • the ribs therefore form a kind of run-on slope for the material pushed outwards away from the opening roller due to the centrifugal force and can thus prevent a jam around the respective opening roller.
  • this wall extends at least partially in the direction of transport from a front end to the rear end with respect to a direction of rotation of the associated opening roller. i.e. the ribs run, for example, helically along the axis of rotation of the respective opening roller and thus support the movement of the material to be cleaned along the desired direction of movement along the associated opening roller.
  • Each of the aforementioned opening rollers can have pins which, viewed transversely to the corresponding transport direction, enclose an acute or right angle with the transport direction. i.e. this type of pins can also serve to support the material transport and to avoid a material jam. Alternatively or additionally, these pins also extend in relation to a direction of rotation of the at least one opening roller from a front end to the rear end at least partially in the transport direction, i.e. run helically, associated with the advantages specified in relation to the ribs. Alternatively or additionally, the transfer section can be straight, kink-free and/or curved in the direction of the opening rollers, at least on a side facing the associated two opening rollers. This helps to avoid material jams, since it is known that fiber material in particular tends to accumulate at edges and in kinks.
  • one opening roller is at a greater distance from a floor on which the textile machine is set up than the respective other opening roller. i.e. the opening rollers decrease in height from the inlet towards the outlet. This supports the transfer of the material to be cleaned from one opening roller to the immediately following one by using gravity. Due to the air flow, the material to be cleaned "falls" into the area of action of the subsequent opening roller.
  • an internal cross section of the associated transfer section can decrease from one opening roller to the other opening roller.
  • the air flowing through accelerates along with the material carried along. This reduces the risk of material jamming or sticking, in particular of fiber material, to the walls of this transfer section, for example.
  • Each of the aforementioned devices can have an associated chamber surrounding the opening roller for each opening roller.
  • the transfer section is designed as a tunnel and opens with one end into the one chamber enclosing the one opening roller in such a way that that of the one opening roller transported fiber material due to the rotation of this opening roller and the resulting centrifugal force acting on the transported fiber material and an existing volume flow (moving air and fiber and foreign material contained therein) automatically reaches one end of the transfer section.
  • the other end of the transfer section opens into the other chamber enclosing the other opening roller in such a way that the fiber material coming from the one opening roller automatically reaches this other chamber due to its speed. This ensures that the fiber material gets safely from one opening roller to the following opening roller.
  • the chambers also prevent material from getting outside the effective range of the opening roller.
  • a transition between an inner side of at least one of the two chambers, which faces the respectively enclosed opening roller, and the transfer section is preferably designed without kinks, combined with the advantages with regard to the aforementioned possibility of designing the transfer section without kinks.
  • the freedom from kinks can be achieved by means of rounded edges, which is easy and inexpensive to produce.
  • the device has a discharge section.
  • the discharge section includes one discharge chamber per chamber. One end of each discharge chamber opens into a discharge pipe which is common to at least two immediately adjacent chambers. At the respective other end of the respective discharge chamber, opposite the one end, a grating section is arranged, which separates the respective discharge chamber from the associated, enclosed opening roller.
  • the discharge pipe has a discharge opening, which is followed by a discharge pipe, and a transport section. Of the Transport section is designed and arranged to transport material coming from the connected discharge chambers to the discharge opening. Because of the grate section, the removal section is provided for removing separated material from the fiber-air stream that is guided over the opening roller that is accommodated in an associated chamber. This arrangement has the advantage that the excreted material can be discharged centrally from the device. This reduces the costs compared to two cellular wheel sluices and simplifies the entire structure.
  • one of the ends of the discharge chambers is closer to the ground than the other ends.
  • the separated material thus falls in the direction of the discharge pipe.
  • At least one discharge section is designed to taper from its other end to its one end. This safely guides the separated material towards the discharge pipe.
  • the discharge pipe can be designed as a tube open at both ends, in whose wall forming the tubular cross-section the associated discharge chambers open at one end.
  • a tube is a space-saving and inexpensive way of conveying the separated material out of the device.
  • the discharge section can have a conveyor wheel.
  • the feed wheel is arranged in the discharge pipe in such a way that its axis of rotation extends along the longitudinal extent and transversely to the outlet openings to the connected chambers.
  • the discharge section also includes a drive section.
  • the drive section is designed to set the impeller in rotation.
  • the discharge section can be designed as a cellular wheel sluice.
  • the discharge pipe is preferably open at both ends, that is to say at both end faces, and the feed wheel is designed as a cellular wheel. This enables the excreted material to be safely transported away.
  • the discharge section can also be designed as a screw lock.
  • the discharge pipe is closed at least at one end and the feed wheel is designed as a worm wheel. This enables an additional degree of freedom with regard to the arrangement of the discharge opening, it can also be arranged on the front side.
  • a textile machine according to the invention has one of the aforementioned devices.
  • the textile machine can be designed as a cleaner, stage cleaner or feeder.
  • the invention can therefore be used universally.
  • the device has the chambers specified above, provision is preferably made for one chamber to be delimited on one side by a housing wall of the textile machine.
  • This housing wall is closest to a transfer section and has at least one through opening.
  • This at least one passage opening is formed in the region of the opening roller that is accommodated in each case. Since the material to be cleaned is moved by vacuum through the textile machine at the opening rollers and through the at least one transfer section, the through-opening means that, from a physical point of view, the resulting overpressure in the surrounding area of the relevant chamber leads to this that through this at least one passage opening air is pressed into the interior of this chamber.
  • the at least one through-opening thus forms a type of secondary air opening.
  • the compressed air can come from air that has been taken from the incoming material flow on the inlet side of the textile machine, for example by means of a condenser.
  • the transfer section can also be arranged at a distance from this inner wall without running the risk of material being deposited between the transfer section and this inner wall. This gives more freedom in arranging the transfer section in the textile machine.
