Definitions

  • the invention relates to a device with the features of the preamble of the first claim.
  • the throughput of such pullers can be improved, for example, by arranging a plurality of grippers. As described in CH-PS 424 568, for example, the grippers are moved over a certain distance section in synchronism with the arbors of the cops on a spinning machine. Such a device is also relatively expensive and also tied to a dense and divisional arrangement of the cops, as is given within the spinning machine on the spinning spindles.
  • the object of the invention is therefore to propose a device of the type mentioned at the outset, which is of simple construction and ensures a high throughput.
  • the solution according to the invention permits continuous, continuous operation. No additional measures are required, for example to precisely cycle the stripping means depending on the delivery of the sleeves. Rather, the invention allows full functional reliability of the removal of the sleeves, regardless of the distance at which the sleeves are transported along the transport path. This means that this device is also less prone to failure and uncomplicated to set up.
  • the resilient arrangement of the pulling means also allows the easy removal of sleeves of different diameters, since the gap width between the pulling means is determined by the sleeves themselves.
  • the form-fitting transport of the individual carriers in the region of the transport section along the pull-off means permits a relatively strong clamping of the coil sleeve by the pull-off means without the transport of the individual carriers being slowed down or even stopped.
  • the transport direction of the pulling means is a result of the transport and pulling direction of the bobbin tubes, the pulling takes place very evenly and largely without slippage.
  • an orderly placement of the coil sleeves is facilitated.
  • the invention can also be implemented with a pair of rollers whose longitudinal axes can be arranged parallel to the direction of transport of the bobbin tubes.
  • the tapered design of the inlet side of the bobbin tubes allows the bobbin tubes to easily enter the roll gap.
  • the clamping point of the sleeves runs spirally around the circumference of the rollers, which advantageously have a rubberized surface.
  • the device according to the invention is arranged on a transport section on which the plug-on mandrels with the attached coil sleeves assume a horizontal position, the coil sleeves, after being pulled off, can fall directly into a collecting device arranged under the removal means by their own weight. As a result, additional transport means, which transport the bobbin tubes from the removal means to a tube store, are not required.
  • This transport section can be arranged, for example, on a bridging of an operating aisle.
  • the pulling device according to the invention is arranged on a cop and sleeve bridge 101, which forms a so-called service aisle.
  • Individual carriers 2 are guided over this cop and sleeve bridge 101 in the vertical orientation of their base plates 5.
  • the respective plug-on mandrel 3 of the individual carrier 2 and the respective sleeve 1 plugged onto it assume a horizontal position in space.
  • the individual carriers 2 are guided through guide plates 9 during their transport over the cop and sleeve bridge 101 on a base 6 arranged between the arbor 3 and the base plate 5, so that they always assume a defined position during their transport.
  • the underside of the base plates 5 lies on a support plate 10 during transport.
  • the base plate 5 of the individual carriers 2 each has a plurality of webs 5 ′′, which connect the base 6 to a casing ring 5 ′. Between these webs 5 ′′ there are openings in the base plates 5, through which driver pins 8 fastened to a chain 7 at equal intervals These driver pins ensure a form-fitting transport of the individual carriers 2 via the cop and sleeve bridge 101. Further explanations of the transport system for the individual carriers 2 are given below in connection with FIG.
  • FIG. 1 and 2 show a device according to the invention, in which the winding of the bobbin tubes 1 takes place essentially by means of two pairs of belts 11/24 and 12/25, which are arranged approximately at an angle of 45 degrees to the transport direction of the individual carriers 2.
  • the transport speed of the belts 11, 12, 24 and 25 is chosen so that the movement component parallel to Transport direction of the individual carriers 2 corresponds to the transport speed of the chain 7. This results in a very even draw-off, which takes place with almost no slippage of the bobbin tube 1 between the two pairs of belts.
  • the spool sleeves 1 are guided by the two pairs of belts 11/24 and 12/25 over their entire length so that they keep their orientation in space up to the downstream end of the two pairs of belts.
  • the coil sleeves 1 can be deposited in an orderly manner.
  • the individual carriers 2 maintain their continuous movement during the removal.
  • a high transport capacity of the cop and sleeve bridge 101 can be ensured, which is not impaired by the removal of the coil sleeves 101.
  • a spring cage 4 is arranged on the arbor 3 of the individual carrier 2, which rests against the inside of the bobbin tube 1 and fixes it so that it can be used in all upstream machining operations, such as in one Not shown cop preparation station or in the respective winding position of the winding machine assumes the required stable position.
  • the pulling device shown also overcomes this holding force of the spring cage 4 when the coil sleeve 1 has sufficient clamping force.
  • compression springs 37 are provided, for example, which act on a holder 19 which is connected to support plates 15 and 18. Pulleys 13 and 14 for the belts 11 and 16 and 17 for the belt 12 are mounted in these support plates 15 and 18.
  • the belts 11 and 12 are arranged opposite the other belts 24 and 25.
  • the belts 24 and 25 are supported by pulleys 26 to 29, which are mounted in support plates 30 and 34.
  • the support plates 30 and 34 are on one Bracket 20 attached, which in turn is fixed to a frame 40.
  • This frame 40 has a vertical part and an angled horizontal part. While the vertical part is attached to a mounting plate 41 'of the machine frame 41 and directly supports the holder 20, a T-shaped rail 40' is attached to the horizontal part, which is overlapped by claw-shaped struts 19 'of the holder 19.
  • the claw-shaped struts 19 'fixedly connected to the holder 19 can slide vertically over the T-shaped rail 40'. Due to the force of the compression springs 37, the holder 19 is pressed in the direction of the holding plate 20, as a result of which the required clamping force for the coil sleeve 1 to be removed is achieved.
  • the angled part of the claw-shaped struts 19 ' forms a stop against the T-shaped rail 40'.
  • the cushioning can be used in the region of the deflecting rollers 13/14 and 16/17, as a result of which the width of the gap 38 along its longitudinal extent is different during the passage of the respective coil sleeve 1.
  • the gap on the entry side of the coil sleeve 1 can open, while it still has the smallest width at the downstream end of the gap 38.
  • the same construction of the cushioning can be used in the area of the gap ends as in the variant of the central cushioning already described.
  • the frame 40 has elongated holes 40 ′′ for fastening to the fastening plate 41 ′ of the machine frame 41, through which screws 39 are guided which can be screwed into the fastening plate 41 ′.
  • the Elongated holes 40 ′′ ensure an adjustment of the frame 40 in order to be able to adapt the entire pulling device to sleeve diameters that may differ considerably. Smaller variations in the sleeve diameters are automatically compensated for by the resilient arrangement of the holder 19.
  • the overlying arrangement of the parts of the trigger device carried by the bracket 19 can also be used to generate the contact pressure by pure weight loading. In the simplest case, this can be done through the weight of these components. If a higher load is required, additional weights can be attached. These can be metal disks, for example, which can be pushed onto a vertical bolt with a central hole. The bracket 19 can be attached directly to the vertical part of the frame 40 via known parallel guides, whereby tilting of the bracket 19 is avoided. For reasons of clarity, these constructions, which are common in mechanical engineering, have not been shown.
  • the belts on the belt pulleys carrying them can be designed as toothed belts, in which case the deflection rollers would also have teeth.
  • a belt thickness can be used which allows the surface of the belt to be adapted to the coil sleeve 1 to be removed.
  • the frame 40 is moved further towards the machine frame 41 in order to change over to a larger sleeve diameter.
  • the holder 20 and the support plates 30 and 34 fastened to it are displaced away from the gap axis.
  • the holder 19 is moved toward the gap axis of the gap 38.
  • the spring travel of the compression springs 37 is simultaneously increased during the passage of a coil sleeve 1 through the gap 38. Associated with this is an increase in the contact pressure and thus also pull-off force of the pulling device on the coil sleeves 1. It is assumed that the larger sleeves are also held more firmly on the arbor 3 or the spring cage 4 of the individual carrier 2 carrying them.
  • the belts 11 and 12 are driven by a motor 44, while the belts 24 and 25 are driven by a motor 44 '.
  • the motor 44 drives the pulley 16 for the belt 12 and a pulley 21 which is arranged on the same shaft.
  • a belt 22 is placed, which drives a drive shaft 36, which is mounted in the support plates 15 and 18 and is connected to the pulley 13.
  • the pulley 13 in turn drives the belt 11.
  • a corresponding drive is provided for the belts 24 and 25.
  • the motor 44 ' drives the belt 25 directly via the pulley 26.
  • a further pulley 33 lying on the same shaft with the pulley 26 is connected to a further pulley 34 via a belt 32. This is attached to the drive shaft 35, which drives the pulley 28 and thus the belt 24.
  • a drive of the entire pulling device which is derived from the chain 7 for the transport of the individual carriers 2, is also particularly advantageous. This not only saves a drive motor, but above all ensures completely synchronous operation. This could be achieved in a simple manner by removing the movement via a chain wheel engaging in the chain 7. The transfer to the individual belts of the pulling device could then take place in the manner described last.
  • the respective upstream pulleys 14, 17, 29 and 30 form, together with the belts 11, 12, 24 and 25 deflected by them, an enlarged gap width required for the jerk-free entry of the bobbin sleeves 1, which corresponds in the transport direction to the outer diameter of the bobbin sleeves 1 Gap width of the gap 38 merges.
  • supports for these belts can be arranged along the gap 38 between the respective pulleys for the belts 11, 12, 24 and 25 for reasons of clarity. These supports can be attached directly to the support plates 15, 18, 30 and 34 and extend from these support plates to below the belt trumes which are adjacent to the gap 38.
  • the surfaces of these supports facing the belts must be smooth in order to keep the coefficient of friction low when they come into contact with the respective belt. They should be at such a distance from the respective adjacent belt that they are only in contact with it when a spool sleeve 1 passes this area of the gap 38.
  • a collecting and collecting device for the bobbin tubes 1, which cooperates with the pulling device, is shown.
  • the spool sleeves 1 are guided by the pairs of belts during the entire pull-off process in such a way that they maintain their orientation in space and can be transferred to the collecting device with this orientation.
  • a baffle plate 47 is arranged adjacent to the downstream end of the pulling device and merges downwards into a shaft 48.
  • the length of the shaft 48 is dimensioned such that the respective spool sleeve largely retains its horizontal orientation when there is no obstacle in the shaft until it meets a conveyor belt 49.
  • the conveyor belt 49 which is driven by a motor 83, transports the respective bobbin tube 1 through an arrangement of a plurality of collecting funnels 51 to 53.
  • a deflecting edge 50 which projects obliquely into the region of the conveyor belt 49, ensures that the respective bobbin tube 1 is dropped from this conveyor belt 49 into the uppermost collecting funnel 51 without changing its orientation.
  • the deflecting edge it is of course also possible to use a known slide which interacts, for example, with a fluid cylinder or a rotating wing.
  • a plunger 46 Arranged in the shaft 48 is a plunger 46 which is displaceable in a fluid cylinder 45 and is intended to turn every second coil sleeve 1.
  • the fluid cylinder 45 is actuated via a control line 42 ′ by the switch 42 already mentioned.
  • This switch 42 transmits to the fluid cylinder 45 each passage of a coil sleeve 1, whereby the plunger 46 is shifted between two dead centers.
  • the switch 42 has caused the plunger 46 to be moved out of the fluid cylinder 45.
  • the plunger 46 which is then arranged outside the center of gravity of the incoming bobbin tube 1, as shown in FIG. 4, ensures the turning of every second bobbin tube 1. Since the bobbin tubes 1 are conical, the turning of every second bobbin tube results a closer arrangement of the same, whereby the storage capacity of a coil container 56 available for receiving the coil sleeves 1 is increased.
  • a sensor in particular a light barrier, above the collecting funnel 51, which causes the two plates of the collecting funnel 51 to pivot in a controlled manner.
  • the control line or the light barrier has not been shown, since the components are known.
  • a further larger collecting funnel 52 is arranged under the collecting funnel 51, the capacity of which is three times that of the first collecting funnel 51, that is to say six bobbin tubes 1.
  • the plates forming this collecting funnel can be pivoted by motors 58 and 61. However, these plates can also be driven by a motor, as already shown. The control of these plates is advantageously effected by the first collecting funnel 51.
  • a third collecting funnel 53 is arranged under the collecting funnel 52, the capacity of which corresponds to four times the capacity of the collecting funnel 52.
  • the emptying of the 24 bobbin tubes 1 collecting hopper 53 is consequently carried out after the collecting funnel 52 has been emptied four times.
  • the collecting funnels 51 and 52 are opened by pivoting each of the two plates, while in the collecting funnel 53 a pivoting path is only shown on one side. The two plates of the collecting funnel 53 are pivoted alternately into the position 53 '.
  • the guide wedge 55 is arranged between two guide plates 54 and fastened to them. These guide plates extend over all three collecting funnels 51 to 53 and form a guide for the coil sleeves 1 at their respective two ends.
  • the guide plates 54 are arranged and dimensioned such that a coil container 56 provided can be pushed over these guide plates 54.
  • the two pivotable plates of the collecting funnel 53 are actuated by motors 57 and 62. If only one motor were used here, a gearbox would have to be interposed, by means of which the pivotable plates could be actuated alternately.
  • the motors 57 and 62 can also be controlled by the collecting funnel, here 52, arranged above them.
  • a counter would only have to activate the motor 57 or 62 after eight emptying of the collecting funnel 52. The control would have to take place alternately. This can be achieved by a counter which actuates one of the two motors 57 and 62 after four emptying of the collecting funnel 52.
  • the arrangement of three collecting funnels it is also possible to provide two collecting funnels. It is crucial that the free fall height of the sleeves does not become too large and that a change in orientation can be expected. In addition, it is also possible to make only one plate pivotable in the one or more collecting funnels arranged above the lowest collecting funnel.
  • the arrangement of the collecting funnels is also not tied to the attachment of the swivel plates in a horizontal plane. So swivel plates below can also be stored in an underlying horizontal plane.
