Definitions

  • the invention relates to a method and a device for feeding a plurality of sleeves or windings wound with textile material on a winding processing machine, the windings being at an axial distance on a receptacle of a transport carriage positioned at the delivery or receptacle point of the machine to be provided.
  • This overhead conveyor system and others offer a very safe, comfortable and material-saving transport device, but it requires larger investments and a corresponding room height.
  • a transport trolley which is provided with a longitudinal receptacle or a transport trough, is automatically loaded at four times on the winding-forming machine (Super Lap), which come to rest in the transport trough.
  • the transport trolley is guided by a guide device on the winding-forming machine and is positioned in time with the delivery point via a displacement device.
  • the wadding rolls are placed at a predetermined distance according to the division of the comb heads of the following combing machine.
  • the positioning device is released and the carriage can be moved manually to the combing machine.
  • the carriage is brought into position on the combing machine via a further guide device, so that the expired sleeves can be exchanged for the full reels.
  • This change is carried out manually, a number of cores corresponding to the supplied windings having to be removed first, in order then to enable the windings to be inserted manually into the unwinding position of the combing machine.
  • the empty tubes are then placed on the loading trough of the trolley and transported back to the winding machine.
  • a transport device for the cotton wrap for transfer to a comber can be found.
  • the windings are brought individually to the respective transfer point on the combing machine via a movable transport carriage and are transferred there to the pick-up point of the combing machine by means of a tiltable trough.
  • the empty sleeves or coils are ejected by a device.
  • This publication does not show how the cores are transported back to a winding-forming machine.
  • the transport trolley is only designed for the tracking of only one roll.
  • the object of the invention is therefore to improve such a system to such an extent that it is possible to change the expired sleeves against the full reels in a partially or fully automatic manner in the shortest possible time.
  • a combing head is to be understood as one of several units which is provided with a combing device for combing out a lap wadding.
  • the pivotable roll plate protrudes upward on its pivoting path into the release mechanism for locking the receptacle. This makes it possible to automatically unlock the receptacle, and at the same time, after the unlocking process, the rolling surface assumes a position which leads to the formation of an approximately closed and obliquely downwardly directed to the combing machine for the automatic feeding of the rolls stored on the transport trolley.
  • the winding rollers are the support rollers on which the windings rest in the combing machine and over which the windings can roll for combing out.
  • the rolling plate or the ejection device can be actuated via a cylinder or an adjustment motor, these actuating devices being controlled by the control of a positioning element and a locking device of the transport carriage, as well as by a sensor for the winding detection a control unit are interconnected.
  • the trolley 1 shows a transport carriage 1, which is in a fixed position on a schematically illustrated delivery table 2 of a winding-forming machine 3.
  • the trolley 1 consists essentially of a frame 10 which is supported on the floor by wheels 11 or steering wheels 12.
  • the transport carriage is provided with a receptacle 6, which is formed by longitudinal pipes 16, 17 attached in the longitudinal direction of the transport carriage, which are connected to one another via rocker arms 14, 14a.
  • the longitudinal tube 16 is mounted on the pivot axis 15 so as to be pivotable about the longitudinal tube 17 via the rocker arms 14, 14a.
  • the coils 7 rest on the two longitudinal tubes 16, 17 during transport. In this position, the two rocker arms 14, 14a are held in their transport position by a lock 22.
  • a spring 18 or 18a is attached to the two rocker arms 14, 14a, which cause a pivoting against the direction of force of the winding weight.
  • a bottom plate 13 which is inclined at an angle to the transfer direction, is fastened, onto which the windings 7 only reach after releasing the lock 22 and when the longitudinal tube 16 tilts.
  • the latch 22 is supported in the position shown on a stop 19 of the frame 10.
  • a receiving groove 21 is provided in parallel for receiving the empty sleeves 20.
  • the length of the receiving channel 21 corresponds to the length of the receiving channel 6.
  • the receiving channel 21 is provided with a feed plate 23 directed obliquely outwards and upwards.
  • the feed plate 23 and the bottom plate 13 are arranged converging to one another.
  • the dispensing table 2 is provided with a trough 4, in which the winding comes to rest when it is dispensed.
  • the transport carriage 1 Since only one winding is delivered in each case in the winding-forming machine, the transport carriage 1 must be shifted in the longitudinal direction by at least one winding width in each case for loading. The shift is usually carried out by the degree of division which the comb heads of the following combing machine have. This is done via an adjusting mechanism 8, which will not be discussed in more detail here.
  • the transport carriage 1 is guided in the longitudinal direction via a guide 9 via guide elements (not shown) attached to the transport carriage at the delivery point of the winding-forming machine.
  • the winding transport carriage 1 is designed to accommodate four windings 7. After the fourth winding has been brought onto the transport carriage 1, the adjusting mechanism 8 disengages and the carriage 1 can be moved with the windings 7 to a subsequent winding processing machine, 25 for example a combing machine. This shift can take place either manually or automatically via a control system if the carriage 1 as indicated in FIG. 2 by dash-dotted lines, has its own drive unit 24.
  • the transport carriage 1 is brought on the back of a schematically indicated combing machine 25 via guide rollers 26 into a guide rail 27 which extends along the combing machine 25 into a fixed changing position. If the trolley 1, e.g. 3, the corresponding position to the individual combing heads is reached, so it is automatically or manually fixed or locked in this position via a positioning element 28.
  • FIG. 3 shows two transport carriages 1 in use, which are already in a positioned change position on the combing machine 25, both transport carriages 1 being connected to one another via a coupling 29.
  • guide plates 52 are attached between the windings 7.
  • Fig. 2 also shows the winding rollers 32 and 33 of a combing head of the combing machine on which the coils 7 are placed for unrolling for the combing process.
  • the direction of arrow A shows schematically the unwinding direction of the winding wadding from the winding 7, which is then combed out by means of a combing device, not shown in detail.
  • a swiveling roll plate 30 is attached behind the winding roller 33.
  • the rolling plate 30 is adjustable via a cylinder 34, for example a pneumatic cylinder.
  • an ejection device 35 which consists of a two-armed lever 36 which is pivotably mounted about an axis of rotation 37.
  • a cylinder 38 is articulated, which causes the pivoting movement.
  • the arm 36a of the lever 36 arrives between the two winding rollers 32, 33 and thereby removes the empty sleeves 20.
  • the corresponding arrangement of the axis of rotation 37 of the lever 36 simultaneously causes the empty sleeves 20 to be lifted in the direction of the rolling plate 30.
  • a sensor 39 is attached below the winding roller 32, which signals when the winding tube has no more cotton or has expired.
  • the actuation or actuation of the cylinder 38 takes place via a valve 40 and that of the cylinder 34 via a valve 41.
  • the valves 40, 41 are connected to a central control unit 44 via a line 42, 43.
  • the sensor 39 is connected via a line 45 and a sensor 46 via a line 47 to the central control unit 44.
  • the sensor 46 is used for the longitudinal positioning of the transport carriage 1 on the combing machine 25, it cooperating with a contact surface 48 of the transport carriage 1. This sensor 46 could also be designed as a switch actuated mechanically from the transport carriage 1.
  • the transport carriage 1 In fully automatic operation, as indicated by dash-dotted lines, the transport carriage 1 is provided with its own drive 24.
  • the trolley 1 is guided over a predetermined guide track via a sensor, not shown in detail.
  • the self-propulsion 24, or its control, are then linked to the control unit 44 via a control computer 49 in terms of control.
  • the drive control 50 of the drive units for the combing machine is also connected to the master computer.
  • the transport trolley 1 is loaded with four coils via the ejection ram 5, it is brought manually or automatically to the rear or feed side for the full reel of the combing machine 25 via a control system.
  • two transport carriages 1, which are connected to one another via a coupling 29, can also be fed to the rear of the combing machine 25.
  • Each transport carriage 1 is provided in the lower side area with spaced-apart guide rollers 26 which are inserted into a guide rail 27 of the combing machine 25.
  • the or the trolley 1 is aligned parallel to the combing machine or to the individual combing heads.
  • the alignment in the longitudinal direction or in the transfer position to the individual combing heads takes place via a sensor 46, which cooperates with a contact surface 48 of the transport carriage 1. If a signal is picked up by the sensor 46, the transport carriage 1 is acted upon by a positioning element 28, which is connected to the control unit 44 via a line 51, and fixes this position. Simpler solutions are also conceivable here, the transport carriage 1 being positioned via an end stop which is connected to a locking element.
  • the transport carriage 1 is now in a fixed change position for the winding 7 or the sleeves 20.
  • This sensor 39 is a light / dark sensor which emits a signal when the white wad of cotton has run off the dark or black sleeve surface.
  • the rolling plate 30 is then controlled automatically or manually via the pneumatic cylinder 34 via the valve 41 and swivels into a lower position shown in dot-dash lines. If this position is reached, this can also be sensed by a sensor, the cylinder 38 is actuated manually or automatically via the valve 40 and causes the arm 36a to pivot, as a result of which the sleeves 20 are released onto the rolling plate 30. In the example shown, four sleeves are ejected simultaneously. The sleeves automatically roll over the rolling plate 30 and the feed plate 23 into a receiving channel 21 of the transport carriage 1 and come to rest there.
  • the rolling plate 30 is then pivoted via the pneumatic cylinder 34 into an illustrated upper position, releasing the lock 22 of the receptacle 6 or the rocker arm 14, 14a.
  • the lock is raised from the stop 19 and released.
  • Due to the winding weight of the winding 7 (up to 25 kg), the rocker arms 14, 14a and the transverse shaft 16 are pivoted against the spring force of the springs 18, 18a about the pivot axis 15 into a lower position shown in dot-dash lines. Since the windings do not rest on the bottom plate 13 arranged below in their transport position, an acceleration is obtained until they rest on this plate when the longitudinal tube 16 is lowered. This ensures that the coils 7 also roll safely from the trolley 1 to the combing machine during the transfer process.
  • the rolls 7 roll into the receptacle between the two winding rollers 32 and 33.
  • the arm 36a of the ejection device is brought back into a lower position.
  • the rolling plate 30 is pivoted again into a lower position shown in broken lines, as a result of which the lock 22, which is likewise acted upon by a spring (not shown), is returned to a locking position can. This is done by returning the rocker arms 14, 14a via the springs 18, 18a to the solid position, one arm of the lock 22 coming to rest on the stop 19 and thus assuming a fixed locking position.
  • the exchange process of the empty sleeves 20 against the full rolls 7 has already taken place in the transport carriage 1 arranged on the left, while it still has to be carried out in the right transport carriage.
  • the triggering or the carrying out of the change process can be carried out either manually via a control panel, semi-automatically via a control unit 44 or fully automatically via a control computer 49. If a master computer 49 is used, the drive control 50 of the drive units of the combing machine 25 is also included, i.e. the operator is only assigned monitoring tasks.
  • a basic prerequisite for this fully automatic operation is the automatic setting of the outgoing with the newly introduced wadding, which is not shown here.
  • the positioning element 28 is released, i.e. the or the trolleys 1 are released again and can be guided out of the guide rail 27 manually or automatically.
  • the empty tubes 20 are then returned to the winding-forming machine 3, in which they are delivered to the machine by hand or automatically.
  • the transport or change process of the winding 7 can now begin again.
  • the proposed transport and changing system considerably simplifies the process, ie the manual operations are reduced to a minimum, and in the case of fully automatic operation even limited to very few monitoring interventions. It will be a simultaneous recording guaranteed by several winding sleeves 20, intermediate storage of the sleeves when placing the winding 7 is no longer necessary. In addition, it is possible for the operator to carry out the entire changing process from a central point in front of the combing machine 25.
