Definitions

  • the invention relates to a bobbin changing and transport system for sleeves and cops with pallets.
  • DE-OS 32 35 442 describes a spinning winder combination in which the pallets, which carry cops or sleeves, circulate in a closed loop between the two machines. It is necessary that both machines are matched to a given pallet size. The system is rigidly defined with this uniform pallet size. In particular if the manufacturer of the spinning machine and the manufacturer of the winding machine do not match, different pallet sizes and types are used. In this case, the transport system mentioned can no longer be used.
  • EP-A-0 402 762 (state of the art according to Art. 54.3 EPC) has already described a machine network between spinning and winding machines, which provides separate transport loops for winding machine-specific and spinning machine-specific pallets. These two transport loops have a contact area in which both types of pallets are arranged adjacent. This contact area has transfer devices for exchanging the cops and sleeves between the different types of pallets.
  • the contact area consists of a mixing section common to the two transport loops, in which both types of pallets are alternately arranged and which is delimited by a feed-in and discharge-side junction of the transport loop for the spinning machine-specific pallets.
  • the object of the present invention is to propose a spool changing and transport system for sleeves and cops with pallets on which the cops and sleeves are placed, which enables a quick and safe exchange of the cops and sleeves between the two types of pallets.
  • a mixing section in which the two types of pallets are arranged “nested”, allows a very quick and safe exchange of the cops and sleeves between the two types of pallets.
  • the mixing and, after the changing process, the separation of the two types of pallets is carried out by arranging them in different levels in a simple and also very safe manner.
  • the mixing section can also be adjusted to different pallet dimensions without great effort.
  • the spool change and transport system is not only tailored to a direct machine network, but is also suitable, for example, for a flexible transport system with a transport trolley, as described, for example, in German patent application P 39 35 627.2. In this case, the mixing section would be between to arrange the trolley and the closed transport system of the spinning or winding machine.
  • the form-fitting transport of the winding machine-specific pallets allows exact positioning within the mixing section.
  • the nested arrangement of both types of pallet ensures an equally exact positioning of the spinning machine-specific pallets between the winding machine-specific pallets.
  • the shoulders of the plug-in mandrels of the two types of pallet serving as a support for the sleeve base of the cops or sleeves are arranged at approximately the same height in the mixing section, the cops or sleeves can be pushed back onto the new plug-in mandrels after each change. It is particularly advantageous if the arbors are designed so that the cops or sleeves are relatively tight.
  • a feed pivot lever should be provided at least for the feeding of the last pallets, where the lack of back pressure no longer generates such a large thrust force become. However, this may already be necessary if the system is operated at high speed.
  • the form-fitting tensioning of the feed swivel lever by the following pallet ensures precise movement coordination.
  • controlling an ejector at the end of the mixing section for the spinning machine-specific pallets by means of positive clamping against the force of a spring has the same advantage.
  • the nested arrangement of the two types of pallets in connection with a stepped transport channel allows the two types of pallets to be safely separated without the use of sensors.
  • the transfer device must be able to lift the cops or sleeves vertically to such an extent that unhindered transfer is possible.
  • the horizontal movement required for the transfer process can take place either from the transfer device itself or from the pallets arranged under the lifted cops or sleeves.
  • the first variant is advantageous for gripping devices that grip the cops or sleeves approximately in the middle
  • the second variant is suitable for relocating devices that grip the sleeve tips. This results in particular from the fact that with a rapid horizontal movement of the cops and sleeves gripped at the tips of the sleeves, high moments of inertia occur.
  • the priority for the winding machine-specific pallets and the insertion of the spinning machine-specific pallets between them was specified as the primary solution.
  • the invention does not include a, that is, a forced guidance of spinning machine-specific pallets, between which winding machine-specific pallets are inserted, is also covered by the present invention.
  • dishwasher-specific pallets 1 which are covered with sleeves 4 are fed to the transport area of a chain 5 by a conveyor belt 8 along a transport path 7.
  • the conveyor belt 8 is deflected by a deflection roller 8 '.
  • the pallets 1 are guided along the transport path 7 on their base plates.
  • the supply of the pallets 1 to the transport area of the chain 5 takes place in the deflection area of the chain 5 formed by the chain wheel 5 '.
  • Carriers 6 attached to the chain 5 at the same distance from one another protrude into the transport path of the pallets 1 and guide them in a form-fitting manner through the transport section 7'.
  • the transport sections have slot guides 7 ′′, 17 ′ and 9 ′′, which allow the drivers 6 to pass through.
  • the chain 5 is deflected by the sprocket 5 ', by the sprocket 5'', by a tension pulley 12 and a drive sprocket 11.
  • the drive sprocket 11 is connected to a motor 15, which is connected via a control line 15 ' is controlled by a central control unit 16.
  • a tension spring 13 acts on the tensioning roller 12 and is attached to a holder 14 at its other end. In this way, the chain 5 is always kept under tension.
  • the transport path 20 is arranged at a height level which corresponds at least to that of the upper sides of the base plates of the pallet 1 specific to the winding machine.
  • These pallets 1 have base-like structures 1 'which form an intermediate space into which the spinning machine-specific pallets 2 can enter. This space results from the dimension of the base plates of the dishwasher-specific pallets 1, the dimensions of the drivers 6 and the diameter of the base-like structures 1 '.
  • An adaptation to the dimensions of the spinning machine-specific pallets is easily possible, for example, by changing the base-like structures 1 'if pallets with exchangeable structures are used. However, it is also possible to place differently dimensioned removable rings on the base-like structures 1 '.
  • Such interchangeable rings or structures for the pallets can serve different purposes, such as differentiating the pallets for different parts of the spools
  • the adaptation to different diameters of the base plates of the pallets 1 can be achieved by replacing the drivers 6. However, it is usually also necessary to replace or adjust the lateral guides of the pallets, which will be described later.
  • an additional device for feeding the spinning machine-specific pallets 2 was dispensed with at the junction 18.
  • This waiver is possible if either the conveyor belt 21 runs so fast that a sufficiently fast feeding of the pallets 2 between the base-like structures 1 'is ensured or the chain 5 is moved so clocked that it is between the foremost pallet 2 during insertion the dishwasher-specific pallets 1 stops at the junction 18.
  • the dynamic pressure is so great that a safe insertion into the mixing section 17 starting at the junction 18 is possible.
  • the dynamic pressure generated on the transport path 20 can be sufficient even if the chain 5 is moved continuously during the insertion.
  • FIG. 1 a feeding-in process of a pallet 2 specific to a spinning machine has just been completed at the junction 18. It can also be seen that the foremost pallet 2 on the conveyor track 20 is in contact with the already inserted pallet 2, which she has moved to the position shown.
  • the foremost pallet 2 standing on the transport track 20 already slides into the mixing section 17 in a first stage until it comes to rest against the base-like structure 1 'of the subsequent winding machine-specific pallet 1 . Then it slides on this base-shaped structure 1 'further into the mixing section 17 until it has reached its central position in the mixing section 17, as is shown in FIG. 1 using the preceding pallet 2.
  • the complete reaching of the intended position in the mixing section 17 extends to just behind the junction 18 when the last phase of the insertion movement by rounding off the cover plate 40 'shown in FIG. 4, for example is taken over with a leading edge 41.
  • a transfer device described later is arranged, which transfers the cops 3 and sleeves 4 to the respectively adjacent pallet of the other type.
  • a further junction 19 is provided, which is arranged at the same height level as the junction 18.
  • a conveyor track 22 leaves the mixing section 17 and has a conveyor belt 23 which returns the pallet 2 specific to the winder to the spinning machine.
  • a fluid cylinder 24 serving as an ejector is provided according to FIG. 1, which is connected to the central control unit 16 via a control line 24 ′.
  • This fluid cylinder 24 has a plunger 25 which is arranged at a height corresponding to the transport path 22. By means of this plunger 25 spinning machine-specific pallets 2 pushed out of the mixing section 17 and fed to the conveyor belt 23.
  • the control of the fluid cylinder 24 can instead of the central control unit 16 also be carried out by a switch, not shown, which is actuated by the incoming dishwasher-specific pallets 1. This allows a simple control of this fluid cylinder 24, which is also very precise.
  • winding machine-specific pallets 1 carried along the transport path 7 carry empty sleeves 4, while after leaving the mixing section 17 these pallets 1 carry 3 heads 3.
  • the spinning machine-specific pallets 2 brought up by the spinning machine on the transport track 20 initially carry cops 3, while after leaving the mixing section 17, that is to say after the transfer, onto the spinning machine-specific pallets 2 which are guided away from the mixing section on the transport track 22 4 are attached.
  • a detailed description of the conversion process is given below.
  • a feed pivot lever 29 is used at the mouth 18. This feed pivot lever is intended to support the rapid feeding of the spinning machine-specific pallets 2 available on the transport path 20 into the mixing section 17. With relatively fast, continuous movement of the chain 5 in the in / out phase, that is, between the transfer operations, the pushing force of the conveyor belt 21 or the pallets 2 accumulated thereon may not be large enough to ensure safe and fast infeed. In this case, the feed pivot lever 29 is in operation during the entire bobbin changing phase, that is, until the ring spinning machine has been completely cleared.
  • the feed pivot lever 29 is rotatable about a pivot pin 30 arranged in a holder 31.
  • a torsion spring is placed around this pivot pin 30, one leg 36 of which is attached to the holder 31, while the other leg 37 engages the feed pivot lever 29 (see also FIG. 3b).
  • the torsion spring with the spring legs 36 and 37 transmits a torque in the clockwise direction to the feed pivot lever 29.
  • FIG. 2 after a pallet 2 has been introduced, it is pivoted the farthest in this direction, since the pallet 2 specific to the inserted spinning machine-specific pallet 1 and upstream in the transport direction has passed a deflection curve 29 ′ of the feed pivot lever. At this point in time, the subsequent winding machine-specific pallet 1 already reaches the deflection curve 29 '.
  • the feed swiveling lever 29 has a tilting lug 32 at this front end.
  • This tilting lug 32 is connected to the feed swiveling lever 29 via a pivot pin 39 appropriate.
  • a torsion spring which has the spring legs 33 and 34, normally holds the tilting lug 32 in the extended position, as shown in FIGS 2 and 4 can be seen. In this extended position, the tipping nose strikes with its straight rear edge on a stop edge 35 of the feed pivot lever 29. This limits their swivel path in this direction.
  • the tilting nose 32 is pivoted counterclockwise against the spring force in the return movement of the feed pivot lever 29, whereby it can easily pass through the pallet 2 waiting on the conveyor belt 21. It is advantageous if the spring force is not too great so that the pallet 2 is not pushed back against the transport direction of the conveyor belt 21. However, the spring force must be sufficient to move the tilting lug 32 back into its starting position after passing through this pallet 2. Since the tilting lug 32 strikes against the stop edge 35 in the working phase of the feed pivot lever 29, that is to say when a pallet 2 is being fed into the mixing section 17, this cannot tip backwards. Sufficient thrust is thus exerted on the pallet 2 to be introduced.
  • the phase shown in FIG. 4 is then followed again by the phase shown in FIG. 2, that is to say that the named dishwasher-specific pallet 1 leaves the deflection curve 29 ', as a result of which the spring having the spring legs 36 and 37 extends the feed pivot lever 29 into the position shown in 2 recognizable position swiveled.
  • the point in time of the pivoting is precisely due to the positive control of the feed pivoting lever 29 on the arrival of the base structures 1 'from matched two dishwasher-specific pallets 1 formed gap at the mouth 18. This exact coordination also enables the chain 5 to run relatively quickly. This results in high productivity of the entire cop changing process.
  • an ejector lever 26 can also be pivoted about the axis of rotation of a pivot pin 28.
  • the pivot pin 28 is mounted in a holder 27.
  • a torsion spring 38 acts on the ejector lever 26 and is anchored in the holder 27 with its other spring leg (see also FIG. 3a). This torsion spring works counterclockwise.
  • the ejector lever 26 is constantly spring-loaded in the direction of the junction 19.
  • Fig. 2 it can be seen that the ejector lever 26 just loses contact with the base 1 'of a winding machine-specific pallet 1. As a result, as can be seen from FIG.
  • the pallet 2 specific to the spinning machine can be ejected into the transport path 22, on which it is then fed back to the spinning machine by means of the conveyor belt 23.
  • Fig. 3 it can already be seen that after ejecting the spinning machine-specific pallet 2 from the mixing section 17, the next winding machine-specific pallet transported by means of the chain 5 begins with its base-like structure 1 ', the ejector lever 26 again against the force of the torsion spring 38 To pivot clockwise. 4 then shows a later phase of pivoting, but the ejector lever 26 is still resting on the base-like structure 1 'of the mentioned dishwasher-specific pallet 1. This position is then followed by the phase shown in FIG. 2 and already described.
  • stepped guide edges 40 and 41 each for the winding machine-specific pallets 1 and the spinning machine-specific pallets 2 intended.
  • These guide edges are each arranged at such a distance from one another that they guide the respective pallets on the lateral surface of their base plates.
  • a cover plate 40 ' is arranged, which connects the two guide plates 40 and 41.
  • a further inwardly facing cover plate 42 connects to the guide plate 41.
  • the cover plates 40 'and 42 are provided for a secure guidance of the two types of pallets in the mixing section 17, especially for the transfer process of the cops and sleeves. These cover plates absorb the vertical forces, for example when the cops and sleeves are removed.
  • the cover plates 40 ' also serve to guide the dishwasher-specific pallets 1 outside the mixing section 17, in particular to prevent them from tipping over.
  • the guide edges 40 are continuous and extend beyond the mixing section 17 on both sides. In this way, the dishwasher-specific pallets are always guided in a form-fitting manner and therefore always assume defined positions. Particularly in the area of the mouths 18 and 19, it is important that the vertical guide plates 40 are present when the winding machine-specific pallets 1 are used for the positive movement transmission to the ejector lever 26 and the feed pivot lever 29.
  • support plates 40 ′′ adjoin the guide plates 40 above the cover plates 40 ′ and serve as supports for the dishwasher-specific pallets 1 and a guide slot, respectively form slot-shaped passage opening 17 'for the drivers 6 of the chain 5 (Fig. 8a / 8b).
  • FIG. 5 a The starting point for the conversion process is shown in FIG. 5 a, a conversion device 43 being shown here only schematically at first. 5a, there is an empty pallet 1 specific to the winder, as shown in FIG. 5a.
  • the relocating device 43 has already been lowered in order to grip the cops 3 and sleeves 4 at their tips.
  • the captured cops 3 and sleeves 4 are lifted over the mandrels of both types of pallets. It should be noted that the lifting is only necessary to a height at which the sleeve feet are arranged above a plane intended by the tips of the mandrels of both types of pallet.
  • Fig. 5c shows that the chain 5 has been moved back by half a division, whereby the raised cops 3 and sleeves 4 are positioned over the adjacent pallets of the other type.
  • the conversion device 43 does not need to carry out a horizontal movement for this.
  • 5d shows the step of lowering and attaching the cops 3 and sleeves 4 to the other type of pallet. This now results in an empty pallet 1 specific to the winding machine at the end of the transfer path.
  • the transfer device 43 then releases the cops and sleeves and returns to their upper position, that is to say the rest position.
  • FIG. 5e the renewed forward transport of the pallets by half a division is already shown, as a result of which the introduction and removal of spinning machine-specific pallets 2 at the mouths 18 and 19 is initiated.
  • the Chain 5 is moved in its normal transport direction until the empty dishwasher-specific pallet 1 has reached the position according to FIG. 5a.
  • All of these movements are coordinated via the central control unit 16, which also drives the chain 5 in its normal transport direction until this position according to FIG. 5a is reached.
  • This can be controlled very precisely with the help of the chain 5, which is driven by the drive sprocket 11.
  • the drive sprocket 11 can be rotated for further transport by a pitch that corresponds to the distance between the drivers 6.
  • the duration of the movement of the chain 5 in its normal transport direction depends on the size of the transfer device 43, that is, the number of gripping devices.

  • the conversion device 43 is attached to the machine frame 60 via supports 49 and 49 '.
  • a crossmember 50 is mounted on the two supports, on which holders 51 for grippers 44 are fastened.

  • the brackets 51 have two legs 51 'and 51' ', which are arranged in parallel and guide shift rods 52 and 53 longitudinally. Grippers 44 are fastened to the shift rods 52. These shift rods consequently serve for the direct transmission of the vertical movement of the grippers 44.
  • a shift rail 54 is provided for transmitting this movement and has contact with all shift rods 52 of the individual grippers 44.
  • the shift rods 52 are held against the shift rail 54 by the force of compression springs 57, which are each supported on the leg 51 ′′, via the collar 52 ′.

  • This transfer device differs from those previously described in that the cops or sleeves laterally approximately in the middle of it Longitudinal expansion can be detected. Since this position also corresponds approximately to the center of gravity of the cops or sleeves, no or hardly any moments of inertia occur in the event of a horizontal offset. As a result, such a transfer device is also suitable for transmitting a very rapid horizontal movement to the cops and sleeves without problems.
  • the backward movement of the chain 5 by half a division during the transfer process can be replaced by a forward movement of the transfer device in the transport direction of the chain 5.

Analogously to the brackets 51, these fluid cylinders 79 and 80 can also be fastened detachably or displaceably to the cross members. For this purpose, the traverses 78 could have elongated holes, not shown here, through which fastening screws for the fluid cylinders 79 and 80 could protrude.

However, it is also possible to choose a larger stroke for the grippers 82 than that of the grippers 81.
