Definitions

  • the invention relates to a winder according to the preamble of claim 1.
  • the round magazines are not emptied evenly. For example, residual bobbins or also bobbins whose thread end could not be detected are ejected several times at a winding unit. This circular magazine is then empty faster than the neighboring magazines. This can mean that the associated winding unit is empty before the end of the manual refilling cycle, as a result of which the winding activity of this winding unit is interrupted.
  • a bobbin distribution device which consists of a conveyor belt with pockets attached to it at the same distance from one another.
  • the pockets of the conveyor belt forming the distribution device are automatically filled on a head side of the winding machine when the arrival of an empty pocket is detected by a sensor.
  • This device only offers an easily supplementable and sortable supply of payout spools in an easy-to-reach position for the operator.
  • the problem of the distribution of This device does not solve supply bobbins on the individual bobbins depending on the bobbin requirements.
  • the object of the invention is to propose a winding machine which can be loaded manually with little physical strain on the operator and which has a distribution device which distributes the waste bodies onto the winding units as required.
  • a memory for independent individual carriers of the pay-off spools within a transport system which supplies a plurality of winding units with pay-off spools, allows sufficient supply to all of the pay-off units, even under different or changing unwinding conditions.
  • the operator only needs to populate a memory for a large number of winding units with payout bobbins.
  • the structure of the memory is considerably simplified compared to the round magazines provided at each winding station.
  • FIG. 1 Nine spoolers 2 are installed within the frame walls of the machine frame 16.
  • the winding devices are shown in simplified form.
  • Casserole bodies in the form of cross-wound coils 8 are each rotatably supported in a coil frame 7 and rest on a drive drum 9 which drives them by friction.
  • the drive drum is advantageously designed as a reversing thread roller, which thus simultaneously carries out the thread laying.
  • the individual thread guide elements have been omitted in the illustration. Only an electronic thread cleaner 10 and a splicing device 11 for connecting the thread ends in the event of thread breakage or a bobbin change can be seen in the thread path. Above the unwinding point of the respective cop 4, a suction device 12 is shown, which sucks the running thread.
  • a longitudinally divided sleeve 13 is arranged, in which the respective Single carrier 3 with cops 4 stands during unwinding.
  • This sleeve 13 is provided with tangentially opening blowing nozzles (not shown here), through which the beginning of the thread is uncovered and fed to a gripper, also not shown, before the unwinding begins.
  • the sleeve 13 can be opened so that the respective individual carrier 3 with cop 4 or sleeve 5 can be inserted and exported so that it clears the way along a transverse conveyor belt 15.
  • the individual carriers 3 with sleeves 5 or residual copes 6 released from the sleeves 13 are fed through the transverse conveyor belts 15 to a common return belt 18.
  • Guide rails 17 ensure compliance with the transport route.
  • the individual carriers 3 with sleeves 5 or residual copes 6 reach an elevator 22 on the return belt 18 at the end of the winding section. These individual carriers are branched off from the return belt 18 by guide plates 28 and fed to the elevator.
  • a sensor 27 is arranged on this elevator 22, which will be described in more detail below with reference to FIG. 2, which detects residual cops 6, that is to say cops with a winding residue which can still be processed.
  • the sensor 27 is connected to a hydraulic cylinder 23 which actuates a lifting wedge 24 designed as a two-armed lever. If the sensor 27 has recognized a residual cop 6, the lifting wedge 24 remains in FIG. 1 shown rest position when the corresponding individual carrier 3 passes. Thus, this individual carrier 3 with residual cops 6 arrives on a conveyor belt 19.
  • the sensor 27 activates the hydraulic cylinder 23, which pulls a piston and the lever arm of the lifting wedge 24 connected to it to the rear.
  • the front part of the lifting wedge 24 is moved forward, that is, away from the elevator.
  • the incoming sleeve 5 is stripped from the individual carrier 3 carrying it and falls into a ready-made sleeve container 66. So that the sleeves 5 can safely get into this container 66, a slide can be arranged, which was not shown here for reasons of clarity, but the Fig. 2 can be seen.
  • only empty individual carriers 3 or individual carriers 3 with residual copers 6 arrive on the conveyor belt 19.
  • the conveyor belt 19 runs in a guide channel 20 which is inclined at an angle of approximately 10 degrees to the operator and is arranged approximately at table height.
  • the height of the arrangement depends on ergonomic considerations, that is, on ease of use by an operator.
  • a detector 25 is arranged, which has two sensors arranged one above the other, whereby it can detect whether individual carriers 3 transported past are empty or carry a cop 4 or residual cop 6.
  • the lower sensor detects the passage of an individual carrier 3, while the upper sensor arranged above the height of the plug-in mandrel detects whether the individual carrier is occupied or empty. If only the lower sensor of the detector 35 detects the passage of a single carrier, while the upper sensor does not signal a cop 4 or residual cop 6, a downstream line is connected via a line (not shown here)
  • Arranged electromagnetic stopper 33 is actuated, which introduces a plunger 34 into the transport path formed by the conveyor belt 19 and thus stops this individual carrier 3.
  • a Kopswagen 32 is shown only as an example, which can be replaced by other containers, for example a coil container according to DE-OS 15 60 558, which is mounted to be movable along the machine.
  • an elevator 31 which conveys the individual carriers 3 occupied with fresh cops 4 or residual cops 6 back into the lower transport plane.
  • the corresponding individual carriers 3 then arrive on a conveyor belt 29, which conveys them to the rear of the winding machine and thus to feed paths to the winding stations which will be described in more detail later.
  • guide plates 21 With the help of guide plates 21, the individual carriers are fed to the elevator 31, while guide plates 30 ensure the transfer to the conveyor belt 29. In this case, the conveyor belt 29 must have its upper run over the return belt 18 be guided.
  • the guide plates 21 must be designed in such a way that they vertically align the cops 4 or residual copes 6, which are initially inclined slightly forward, before transfer to the elevator 31, in order to avoid a reliable transfer without contacts of the winding surfaces with components of the machine or other cops.
  • FIG. 2 shows the elevator arranged at the end of the respective return path of the return belt 18, designated 22 in FIG. 1.
  • the operation of the elevator can be regulated here with the aid of a switch 40.
  • the sleeve pulling device 49 is designed differently here.
  • the individual carriers 3 fed to the elevator on the return belt 18 along the guide rails 17 are transferred in the illustrated position of the switch 40 from the return belt 18 to drivers 38 fastened to a belt 37 at corresponding intervals from one another. These drivers 38 can engage between the spokes, which connect an outer ring of the base plates of the pallets 3 to a base carrying the plug-on mandrel.
  • the individual carriers 3, after being moved by means of the switch 40 in the direction of the belt 37, are gripped by the next driver 38 and tilted into a vertical position under the guidance of guide surfaces 39.
  • the specific arrangement of belt rolls 44 and 45, which guide the belt 37 together with further belt rolls 46, 47 and 48, results in an inclined transport section before the transition to vertical transport. This oblique transport section prevents 38 adjacent sleeves 5 from interfering with one another in the tilting phase at relatively small distances between the drivers.
  • the guide surfaces 39 merge into c-shaped guide rails 36 in the vertical part.
  • This sleeve pulling device consists of a pair of rollers 50, 51, the roller axes of which are arranged perpendicular to the direction of transport of the sleeves 5.
  • the pair of rollers 50, 51 forms a nip which lies in the plane which is formed by the transport direction of the longitudinal axes of the sleeve.
  • the rollers 50, 51 have 5 conical lugs 50 'and 51' on the inlet side of the sleeves. As a result, the sleeves 5 can easily run into the nip.
  • the rollers 50 and 51 are connected to scissor levers 54 and 55 via bearing bushes 50 ′′ and 51 ′′.
  • Motors 52 and 53 are also fastened to the scissor levers 54 and 55. These motors 52 and 53 form the rotary drive for the rollers 50 and 51, the drive shafts (not shown) of which are mounted in the bearing bushes 50 ′′ and 51 ′′.
  • the drive of the motors 52 and 53 can be influenced by a central control unit via control lines 52 'and 53'.
  • the scissor levers 54 and 55 are held in a closed position by a coil spring 57. However, a stop (not shown) can be provided between the scissor levers in order to avoid that each incoming sleeve 5 to be removed has to completely open the nip itself.
  • the rollers 50 and 51 remain in their illustrated basic position, forming a roller gap, in order to pull them off by the rotary movement of the rollers while the respective tube 5 passes through the roller gap .
  • the removed sleeve 5 then falls on a slide 64 which is connected to the machine frame via a holder 65.
  • the slide 64 then leads directly into the collecting container 66 shown in FIG. 1.
  • the sensor 27 If the sensor 27 detects a residual cop 6, it issues a control command via the line 27 ′ to the hydraulic cylinder 62, which is connected to the machine frame via a holder 63.
  • This hydraulic cylinder extends an actuating rod 61, by means of which a two-armed lever 59 is pivoted about an axis 60 which is also mounted in the machine frame.
  • a roller 58 is fastened, which is pushed between the two scissor levers 54 and 55, but on the other side of the pin 56 forming the fulcrum for these scissor levers.
  • the bolt 56 is also anchored in the machine frame.
  • the pulling device 49 can also be controlled in connection with the sensor 27 via a central control unit (not shown here). It is also possible to put the motors into operation via the lines 52 'and 53' only when a sleeve 5 to be removed is being transported.
  • the individual carrier 3 After passing the pulling device 49, the individual carrier 3 arrives again on a vertical transport path and at the same time on lifting profiles 26, which feed it to the conveyor belt 19.
  • Guide plates 25 are arranged at such a distance above the lifting profiles 26 that they allow the base plates of the individual carriers 3 to pass freely.
  • a guide profile 25 ′ can additionally be worked on, which guides the incoming individual carrier 3 even further onto the conveyor belt 19 on its base carrying the arbor. That is especially then important if the guide channel 20 only begins at a certain distance from the deflection roller 19 'of the conveyor belt 19.
  • the guide channel 20 has an extension 20 ′ at its beginning in order to ensure a bumpless transfer of the individual carrier 3.
  • the storage and the drive of the deflection roller 19 'of the conveyor belt 19 described later are much easier to solve if the axis of rotation of the deflection roller 19' is horizontal.
  • the conveyor belt 19 is slightly interleaved between the deflection roller 19 'and the guide channel 20. This can be solved in a simple manner in that the guide channel 20 is at least with its elevated side a little higher than the upper edge of the deflection roller 19 '. If the conveyor belt 19 lifts something with its upper run on the opposite side of the guide channel 20 at the beginning, it is pressed onto the bottom of the guide channel 20 when an individual carrier 3 is fed in at the extension 20 '.
  • the functionality is not affected in any way.
  • the configuration at the other end of the conveyor belt 19 on the elevator 31 is analogous. However, it is advantageous to connect guide plates 21 there directly to the guide channel 20, which form a positive guide for the individual carriers until they are taken over by the elevator 31.
  • the design of the elevator 31 is analogous to the elevator described above, wherein an inclined guide is also provided in particular by five deflecting rollers for a belt carrying the carriers when the individual carriers 3 are transferred to the conveyor belt 29 in order to prevent the cops 4 from touching one another.
  • the switch 40 can be operated via a hydraulic cylinder 43 with a plunger 42 via a linkage 41.
  • the hydraulic cylinder is controlled via a control line 43 'by a central control unit (not shown).
  • This central control unit can be provided, for example, if all switching steps are to be initiated centrally, in order to switch from section-by-hand operation to central automatic bobbin delivery.
  • FIG. 3 Such a system is shown in FIG. 3.
  • Turnouts 100 and 101 are opened on a return path 102, so that they do not feed individual carriers 3 with sleeves 5 or residual copes 6 located on the return path 102 to the elevators 96 and 98 via guide plates 97 and 99.
