Definitions

  • the invention relates to a device for feeding slivers - or the like in particular from cans.
  • Stacking vessels are weighed - via conveying devices of an infeed table to a textile processing machine, with the conveying path of the sliver being assigned a reserve belt in a standby position, which can be switched on via a control device in the event of breakage or running out of the sliver so that the beginning of the reserve association comes to the end of the leaking sliver is attached.
  • the sliver to be processed is drawn from the spinning can via take-off rollers and placed on a conveyor belt for further transport.
  • Each so-called working jug is assigned in pairs a so-called reserve jug, the sliver of which is taken up as a reserve sliver via a pair of take-off rollers and kept ready.
  • the pairs of take-off rolls of the fiber sliver and the reserve sliver are - seen in the conveying direction - arranged one behind the other in a line.
  • the take-off device of the assigned reserve sliver is started by a control. This ensures the automatic tracking of a reserve bandage if a sliver breaks or runs out.
  • the inventor set himself the task of avoiding the existing disadvantages of known devices, improving the merging of belt ends at any angle between the feed and discharge directions, and the controlled tracking of a reserve belt.
  • the reliable infeed table should be manufactured and maintained in a particularly simple manner.
  • the separately designed conveying paths of the sliver and reserve belt being assigned a common pressure gap, the sliver and the beginning of the reserve belt being able to be fed to the pressure gap lying next to one another.
  • the pressure nip should be designed as a roller nip delimited by rollers, which are arranged on roller axes running approximately vertically to the conveying path of the sliver.
  • one of the rollers is a reversal for a rotating belt conveyor which overlaps the conveying paths of the sliver and the associated reserve belt at an approximately horizontal setting angle.
  • One of the rollers can rest against the strand of the belt conveyor pointing against the conveying direction as a pressure roller.
  • a plurality of pairs of rollers are arranged side by side and their nips are spaced apart in the conveying direction.
  • the axes of the pressure rollers can also be at a distance from one another in the running direction.
  • lateral guides arranged upstream of the roll gap which form a funnel-shaped surface that covers both conveying paths.
  • the invention allows a free band end to be deflected at any angle and the band end to be attached during this deflection; the accelerated reserve belt fed through the infeed table is pressed together with the outgoing belt by the pressure force of the pressure rollers on the conveyor belt.
  • the angle between the inlet and outlet can be freely selected.
  • by using the tangential deflection conveyor it is possible to dispense the belt in all directions or to swap the outgoing end and reserve belt.
  • the conveying devices or conveying paths of the infeed table consist of individual guide elements, in particular conveyor belts assigned to each sliver and each reserve belt and drivable individually or in groups, in particular conveyor belts, which are connected at an angle to at least one conveying transport element.
  • the conveyor belts for the fiber belts and the reserve belts should be arranged parallel to one another and in pairs. It has also proven to be advantageous to connect these conveyor belts, which are combined in pairs, to one another in terms of control.
  • the conveyor belt mass to be moved is limited to a necessary minimum, resulting in lower drive power and less dust.
  • the individual carrier has a drive roller at one end and a deflection roller at the other end, the latter - but also the drive roller - preferably being axially movable on the carrier as a tension roller for the conveyor belt.
  • the carrier can be made from a tubular profile and a U-profile can be placed on it; the upper run of the conveyor belt is stored in its profile space and can be moved in a protected manner.
  • a tube or channel attachment is provided below the tube profile, and at least one support roller in this, in order to prevent sagging.
  • the support roller can also be present outside the channel insert in a cross member holding the carrier; Several parallel beams are gripped by at least one common cross beam as part of the frame of the infeed table, so that this frame needs only a few individual parts.
  • the carrier can be composed of axial carrier sections that are spanned by the conveyor belt; these carrier sections are prefabricated in a predetermined grid dimension with different lengths, preferably a basic basis and one and a half times and twice its size should be present.
  • the drive of the conveyor belt is provided in a drive unit attached to the carrier as a module, which also contains the drive roller engaging in the loop of the endless conveyor belt.
  • a drive unit attached to the carrier as a module, which also contains the drive roller engaging in the loop of the endless conveyor belt.
  • at least one pressure roller can be swiveled on its circumference, which in turn is part of the drive unit or else is articulated outside the drive unit to its support or to the adjacent support - the latter across the conveying direction.
  • An infeed table 10 of a textile machine for the treatment of slivers 12 is arranged above so-called cans 14, from which the slivers 12 are guided onto the infeed table 10 by means of rollers 16.
  • cans 14 reserve cans 14 a are arranged, from which reserve slivers are guided to a run-in table 10 12th
  • the in the conveying direction x front end 12 e of the reserve tapes 12 a are attached to the rear end 12 i of an adjacent sliver 12 to avoid interruptions in the tape feeds.
  • the individual fiber belts 12 and the reserve belts 12 a arrive on separate conveyor belts 18 and 18 a , which - as can be seen for example in FIG. 1 - are of a staggered length and are attached to a dispensing head 20 with their end ends.
  • Fig. 3 at 19 lateral guides are indicated, which flank the belts 12, 12 a over the entire length of the conveyor belts 18, 18 a or parts thereof.
  • a drive roller 23 coupled to a drive 22 for the conveyor belts 18, 18 a . It is not shown that the conveyor belts 18 and 18 a can each be driven separately or in groups via the drive roller 23. Clutches and braking devices (not shown) are assigned to the drive roller 23 and connected to a control unit 24.
  • the delivery head 20 formed by the drive roller 23 and the deflected conveyor belts 18, 18 a is gripped by a relatively short conveyor belt 32 common to the conveyor belts 18, 18 a , the width of which corresponds at least to the width of the delivery head 20.
  • a relatively short conveyor belt 32 common to the conveyor belts 18, 18 a , the width of which corresponds at least to the width of the delivery head 20.
  • two mutually inclined flank guides 34 are attached in such a way that they grip the external fiber belts 12 and deflect them to a conveyor roller 39 - which forms a nip 37 with the rear reversing roller 33 of the conveyor belt 32.
  • intermediate guides 36 are in turn provided inclined to the longitudinal axis A of the conveyor.
  • Each of the guide members 34, 36 is assigned a fiber sliver 12 with an adjacent reserve sliver 12 a .
  • the fiber tapes 12 in FIGS. 3, 4 are guided through the guide members 34, 36 to the roller nip 37 and brought together in the area of a stretch 40 to form a nonwoven fabric 42.
  • two infeed tables 10 for two slivers 12 and two reserve belts 12 a are set at setting angles w, w 1 to the longitudinal axis A of the conveyor and abut a central guide 35 in the area of the dispensing head 20.
  • This straight line G includes the longitudinal axis of conveyance A - in the exemplary embodiment shown at an entry angle t of 90 ° - an angle of incidence t 1 of 130 ° to 140 °.
  • a placed around the two belt rolls 44, 44 a, for example with 2,600 rpm rotating belt conveyor 46 affects the conveyor belt 18 in that setting angle t 1 and takes the fiber belt 12 into a roller gap 47, which is limited by the belt conveyor 46 and a lateral pressure roller 48.
  • a conveyor belt 50 for the running sliver 12 z adjoins the roller gap 47 in the direction of the y.
  • the reserve belt 12 a is fed to the nip 47 and its free end 12 e is pressed together with the outgoing sliver 12 by the pressing force of the pressure roller 48.
  • This connection point 12 i / 12 e receives sufficient strength to the like or the like sliver 12 z in a drafting system. to be able to introduce. It is of no importance whether the conveyor belt 18 for the sliver 12 or the conveyor belt 18 a for the reserve belt 12 a is closer to the pressure roller 48.
  • Both the distances e of the band rollers 44, 44a of deflecting devices assigned to one another in the direction of the discharge y and the distances q of the nips 47 directed transversely thereto can be changed in accordance with FIG. 6.
  • the nips 47 are formed by the rollers 44, 48 without the interposition of a deflection belt conveyor.
  • the short clamping path leads here to less adhesion of the reserve belt 12 a to the fiber belt 12.
  • Figs. 8 to 11 provide details of another embodiment of the run-in table 10 with its separated from each other over separate deflecting rollers 30 run, as well as in the conveying direction x by individual drive rollers 23 a moving conveyor belts 18, 18 a an exemplary width of 40 mm again.
  • the drive roller 23 a is not provided at the transfer point 11 near the motor 12, but rather is part of a modular drive unit 25, in which a separate drive is integrated.
  • This drive unit 35 sits at the feed end 11 of an iw horizontal support 38, which is assembled from a plurality of support sections 38 a , 38 b , 38 c ; 8 are used, for example, in three different lengths n 1, n 2, n 3 in order to be able to produce as many different total lengths n as possible for the carrier 38.
  • the length n1 of the support section 38 corresponds to half the length n3 of the support section 38 c , the length n2 of the support section 38 b of one and a half times the length n1.
  • the beams 38 composed of those beam sections 38 a , 38 b , 38 c in staggered overall lengths n rest on common cross beams 52, which in turn are connected to vertical supports 54.
  • Each carrier 38 forms with its drive unit 25 and the deflection roller 30 attached at the other end an exchange unit and is part of a frame 56 of the inlet table 10 with the cross members 52 and the vertical supports 54 - the foot regions of which are neglected in the drawing.
  • the lower run 18 t of between deflection roller 30 and drive roller 23 a spanned conveyor belt 18 or 18 a is located on support rollers 31 which prevent slack.
  • the carrier 38 or the carrier sections 38 a , 38 b , 38 c have, according to FIG. 12, a supporting tube profile 58, under which a tube or channel attachment 60 receiving those support rollers 31 is riveted or screwed.
  • a tube or channel attachment 60 receiving those support rollers 31 is riveted or screwed.
  • the drive unit 25 is attached to the feed end 11 of a tubular profile 58.
  • a pressure roller is on-hook 68 and is hinged by means of a rocker arm on a bracket of the adjacent carrier 38th
  • a sensor integrated in the drive unit 25 or arranged in the feed area in another way controls the belt movement as a function of the passage of the sliver 12.
  • the carrier 38 is lifted from its cross members 40 and the portable deflection roller 30, which serves as a tensioning roller, is released. After applying a new conveyor belt 18 or 18 a , this is tensioned by the deflection roller 30, and the carrier 38 is used again.
