- Fig. 1 shows only the elements necessary for understanding the invention a textile machine, here a spinning machine 1, the work or spinning positions 10 empty tubes 2 are each fed in a precisely defined position.
- Each Work station 10 has two coil arms 11 and 110, between which the delivered Empty sleeve 2 is to be positioned (see dashed line), so that afterwards the spun thread can be wound on it.
- For the Transport of the empty tubes 2 along a variety of similar work or spinning stations 10 of the spinning machine 1 serves a sleeve conveyor device, which according to FIG. 1 two continuous endless belts or bands arranged parallel to each other 12 and 13 (see also Fig. 3), on the upper runs 120 and 130 the Empty tubes 2 rest, while the lower runs 121 and 131 the two returning ones Trums of endless straps or bands 12 and 13 are.
- the two upper runs 120 and 130 are in a guide 140 and the two lower runs 121 and 131 guided and supported in a guide 141.
- the guides 140 and 141 with the help of holders 14 from the machine frame 15 Spinning machine 1 worn.
- a maintenance device 3 which runs along the spinning stations 10 Spinning machine 1 is movable. Depending on your wishes, that the maintenance device 3 only one long side or both long sides operated the spinning machine 1.
- the maintenance device 3 carries a suitable gripping device 30, with the help of which the empty tube 2, which is shut down relative to the spinning station 10, is received in the usual way and transported between the two coil arms 11 and 110 and to this is transferred (see dashed line in Fig. 1).
- the defined stopping of the empty tube fed through the two bands 12 and 13 2 takes place with the aid of a stop carried by the maintenance device 3 4, from a swung-up rest position (see dashed illustration in Fig. 3) can be pivoted down into its working position in which it is in the transport path of the empty sleeve 2 fed on the belts 12 and 13.
- the stop 4 is carried by means of a holder 5.
- Of the Holder 5 is parallel to the transport direction of the empty sleeve 2 adjustable hinge pin 50 on a part 310 of the frame 31 of the maintenance device 3 stored.
- the holder 5 is at a distance from this hinge pin 50 with a rod 51 in connection, which in turn the extension of a piston 52nd a pneumatic or hydraulic cylinder 53 forms.
- the cylinder 53 is in known manner using a conventional and therefore not shown control device controlled to the stop 4 when necessary in the transport path of the empty tube 2nd to swing in or out of this transport route.
- Cylinder 53 can also use an engine.
- the stop 4 has a stop surface 40 which is opposite the sleeve conveying device 12, 13, seen in the sleeve feed direction (arrow f), an acute angle ⁇ includes (reversed in Fig. 2).
- the stop surface 40 a sleeve pressing device, with the help of the empty sleeve 2 against the tapes 12 and 13 of the sleeve conveyor is pressed.
- 1 spools can usually be different on spinning machines Form.
- cylindrical sleeves 25 see Fig. 6 or solid line in Fig. 3
- conical sleeves 26 see Fig. 2 or dashed line in Fig. 3
- the angle ⁇ between the Stop surface 40 and the transport direction of the sleeve conveyor is generally smaller than the angle ⁇ oriented in the same direction between the leading end face 21 of the empty sleeve 2, 25 or 26 and the bands 12 and 13 of the sleeve conveyor (see Figs. 2 and 6). In this way remains in any case, d. H.
- the empty tube 2, 25 or 26 is monitored. This can be done directly with the aid of a monitoring device 6 (see FIG. 1) or done indirectly.
- a light barrier is provided, which the front end face 21 or the trailing end face of the empty sleeve 2, 25 or 26 monitors and triggers a signal when the empty tube 2, 25 or 26 the desired Has reached position. This signal then does not cause the above mentioned shown control device of the spinning machine 1, the stopping of the sleeve conveyor 12, 13.
- the holder 5 is flexible and For this purpose, for example, consists of spring plate.
- a monitoring device designed as a touch device 6 for direct monitoring of the position of the empty tube 2, 25 or 26 arranged, which scans the position of the holder 5 and at each by the emergence the empty sleeve 2, 25 or 26 caused deviation of the holder 5 or his Stop 4, d. H. if its lower end, which forms a switch flag, in the Scanning area of the monitoring device 6 arrives, triggers a signal to the sleeve conveyor 12, 13 to stop or at least to the work of the gripping device 30 initiate.
- An elastic design of the holder 5 also has the advantage that the empty sleeve 2, 25 or 26 is slowed down in a progressive manner, reducing the impact of the Empty sleeve 2, 25 or 26 mitigates and thus further to a quiet shutdown of the Empty sleeve 2, 25 or 26 and thus also contributes to the fact that the empty sleeve 2, 25 or 26 remains securely on the belts 12 and 13 of the sleeve conveyor.
- the attack 4 is in this way due to the elastic bracket by means of the elastic Holder 5 designed as a damping device.
- the torque or tilting moment triggered when the braking process begins with respect to the empty sleeve 2, 25 or 26, and continues to be produced until the belts 12 and 13 of the sleeve conveyor are stopped. If the empty sleeve 2 strikes the stop surface 40, so initially increases due to the elastic design of the holder 5 Angle ⁇ and in this way causes an increase in the torque or tilting moment. Only if due to lower acting forces, e.g.
- the entire holder 5 is not necessary for the entire holder 5 to be elastic.
- an elastic element for example in Form a compression spring or two compression springs or the like., The or which allows the holder 5 to yield (within specified tolerances) or allow, so that in this way the elastically mounted holder 5 in turn Damping device that brakes and stops the accruing Empty sleeve 2 causes in a depreciated manner.
- the monitoring device can also be used here 6 be assigned to the holder 5 and scan its position, what in each usual way (mechanical, optical, inductive, etc.) can happen. In this case can also be dispensed with the stop 4 when the holder 5 itself the angled Has shape in relation to the face of the sleeve and the function of the stop 4 takes over.
- the stop surface 40 train elastic. Due to the high stress on the stop surface 40 it is more advantageous, however, between a rigidly designed and mounted holder 5 and its stop 4 to arrange an elastic element or the stop surface 40 resiliently in the stop 4.
- a piezoelectric element in the Holder 5 a piezoelectric element can be integrated, which due to deformation, which causes an empty sleeve 2, 25 or 26 to run onto the stop 4, emits a corresponding control signal - either only to activate the gripping device 30 (see Fig. 1) or for braking or stopping the sleeve conveyor, before the gripping device 30 becomes active.
- the monitoring device 6 does not necessarily need the position of the empty sleeve 2 to feel directly. Rather, the control device mentioned can be the position the empty tube 2 also due to the time of placing the empty tube 2 on the belts 12 and 13 of the sleeve conveying device depending on their Calculate the speed and the position of the maintenance device 3 mathematically and trigger the individual work steps accordingly.
- the device described is not on limited the training explained; rather, there are numerous modifications in the Possible scope of the invention. So individual characteristics of different Examples exchanged with each other or in other combinations Find application or be replaced by equivalents. For example it is not absolutely necessary, the tilting moment at the leading end 24 of the empty sleeve 2, 25 or 26 to produce by between the stop surface 40 of the stop 4 and the end face 21 of the empty sleeve 2, 25 or 26 an acute angle ⁇ is provided. Rather, it can also be during braking and stopping the empty sleeve 2, 25 and 26, a sleeve pressing device can be provided brought to bear on the trailing end 23 of the empty sleeve 2, 25 or 26 becomes. Such a design of the device for positioning the empty sleeve 2, 25 or 26 compared to that to be equipped with an empty sleeve 2, 25 or 26 Spinning station 10 of the spinning machine 1 is described below.
- Stop 4 still a second holder 5a with a second, also a stop surface 40a provided stop 4a, the two stop surfaces 40 and 40a face each other.
- Direction of transport (arrow f or fa) of the sleeve conveyor (belts 12 and 13) one time the stop 4 and the other time the stop 4a is used, while the stop 4a or 4 not required in each case in its rest position remains (see FIG. 3).
- a monitoring device for the holder 5a 6 can be provided for scanning the position of the holder 5a, which depending on a deflection of the holder 5a, with the usual interposition a corresponding control device (not shown), the tapes 12 and 13 of the sleeve conveyor stops.
- the stop that is not required 4 or 4a remains, as mentioned, with its holder 5 or 5a in its swiveled up position Rest position (see Fig. 3).
- stop surfaces 40a and 40 together in this case are a sleeve pressing device to generate a directed against the sleeve conveyor 12, 13 Torque or tilting moment. It is of secondary importance that the trailing end 23 of the empty sleeve 2 effective stop surface 40th is only used after a delay, because the desired torque and tilting torque already exist by cooperating with the leading end 24 of the empty tube 2 Stop surface 40a is generated.
- the maintenance device 3 carries two stops 7 and 7a, which, however, in each case in mirror image in comparison to the stops 4 and 4a according to FIG. 5 are arranged, d. that is, their inclined abutment surfaces 70 and 70a, respectively wear on the opposite sides of the holder 5 and 5a.
- a monitoring device 6 (not shown) assigned, for example of piezoelectric integrated in the holders 5 and 5a Elements, the emergence of an empty tube 2 on one or the other Register stop 7 or 7a due to the deformation caused thereby and then a pulse to stop or brake the bands 12 and 13 of the Generate sleeve conveyor and to initiate the work of the gripping device 30.
- These piezoelectric elements form the monitoring device mentioned above 6 for monitoring the position of the empty tube to be delivered 2.
- both stops 7 and 7a together brought into the working position shown in the transport path of the empty tube 2.
- the empty sleeve 2 is fed from the right side in the direction of the arrow f, so it runs first, d. H. before reaching their defined stop position, on the stop surface 70a of the stop 7. It causes an if also slight, deformation of the holder 5a, so that the integrated in the holder 5a piezoelectric element triggers a pulse that reduces the transport speed the belts 12 and 13 of the sleeve conveyor device.
- the elastic design of the holder 5a also gently brakes the empty sleeve 2.
- the oblique arrangement of the abutment surface 70a causes a torque or tilting moment on the empty sleeve 2 while it is being braked acts, which reinforces the empty tube 2 against the belts 12 and 13 of the tube conveyor presses. Since the empty sleeve 2 is still the driving effect of the slowing bands 12 and 13 is subject, the empty tube 2 will continue pressed against the stop surface 70a of the stop 7a, so that the tilting moment towards the two bands 12 and 13 continues to be generated continuously becomes.
- the holder 5a is raised so that the stop 7a carried by it from the Transport path of the empty tube 2 is pulled away and the empty tube 2 releases.
- the Empty sleeve 2 can now follow the tapes 12 and 13 again. However, since this only are still driven at a reduced speed, the danger is that the Empty sleeve 2, which is still in its working position within of the transport path of the empty sleeve 2 located stop 7, uncontrolled Movements on belts 12 and 13 are carried out and fall off them, negligible.
- a stop 7 is provided with an inclined stop surface 70.
- the holder 5 shown as an elastic element there is one when the empty sleeve 2 runs up, so that the one not shown in FIG. 4 Angle ⁇ (see Fig. 1) increased so that now a second time during the shutdown the empty sleeve 2 an increasing torque or tilting moment is generated that holds the empty tube 2 securely on the tapes 12 and 13.
- the probe element assigned to the holder 5 for example one on the deformation of the holder 5 responsive piezoelectric element, addressed, the impulse to stop the two belts 12 and 13 of the sleeve conveyor and to activate the gripping device 30.
- the empty tube 2 which is in reverse Direction, d. H. from the left in the direction of the arrow fa, the defined stop position is fed.
- the empty tube 2 first runs on the outside of the Holder 5, d. H. on the side facing away from the stop position of the empty sleeve 2, arranged stop surface 70 of the stop 7, whereupon the reduction the transport speed for the empty tube 2, d. H. of speed of the belts 12 and 13 of the sleeve conveyor. Then will by lifting the stop 7 released the empty tube 2, which is now reduced Speed continues until it passes through the back of the stop 7a is stopped, the holder 5a of the stop 7 stopping the belts 12 and 13 and initiating the work of the gripping device 30.
- the holder 5a carries a stop 7a with a outer stop surface 70a for pre-stopping those fed in the direction of arrow f Empty sleeve 2, while the stop surface 40 carried by the holder 5 des Stop 4 (see Fig. 5) the final stopping of the empty tube 2 in the defined Stop position for their takeover by the gripping device 30 effected.
- the holder 5 carries an inner stop 7 with a stop surface 70 for pre-stopping an empty sleeve 2 fed in the direction of arrow fa, which after renewed release by the stop 7, definitely by the stop surface 70a of the stop 7a is stopped.
- the function of such a modified device is as described above with the difference that in any case if the Empty sleeve 2 runs onto one of the stops 4a, 4 or 7, 7a, but the empty sleeve 2 does not is only braked, but also always the effect of a high tipping moment is subjected, by which it can be safely on the tapes 12 and 13 or in other Formed transport elements of the sleeve conveyor device held becomes.
- the sleeve pressing device forms with their help during the speed reduction of the empty tube 2, 25 and 26 compared to the still higher speed Belts 12 and 13 or the like.
- the sleeve conveyor a tilting moment in Direction to the sleeve conveyor is generated, an integrated part of a or two stops 4, 4a, 7 and 7a, but the sleeve pressing device also deviate from it.
- Sleeve pressing device brought to rest on the empty sleeve 2, 25 or 26 will, because of their resting on the empty tube 2, 25 or 26 working surface and their arrangement and inclination the lagging side of the empty tube 2, 25 and 26 presses more strongly against the belts 12 and 13 than the leading side.
- This sleeve pressing device can by the on the stop 4, 4a, 7 and 7a Bulging empty sleeve 2, 2a or 2b this function mechanically via a linkage or by activating a monitoring device arranged at a suitable point 6 trigger.
- Training and control can be such a sleeve pressing device that the trailing end 23 of the empty sleeve 2, 25 or 26 is brought to rest, are controlled so that they coincide with or substantially simultaneously with the impact of the empty sleeve 2, 25 or 26 on the stop surface 40 or 40a Effect comes what is accordingly by the or another monitoring device 6 can be controlled.
- the holder or holders 5 and / and 5a along the transport path of the empty tube 2, 25 and 26 can be set can or can. This can be done in several ways, for example by adjusting the hinge pin 50 relative to the part 310 of the frame 31 the maintenance device 3 (see FIG. 1). Adjustments along a guide slot can be provided in an alternative manner. This setting option is important especially also when two stops 4 and 4a in pairs for generation of a torque or tilting moment work together.
- the drive of the holder 5 and 5a or the holder 5 can also be different be trained. So instead of a rotary actuator, there is also a linear actuator conceivable (cylinder or rack drive, etc.), the holder 5 and / or 5a each after task (generation of the overturning moment at the front and / or at the rear End of the empty tube 2, 25 or 26, based on their feed direction) horizontally or moved vertically or on an inclined path.
- the invention ensures that the tilting moment, the safe position when braking is always the greatest possible effect. This is achieved in that the stop of the sleeves, whether cylindrical or conical, always at the upper end of the Face of the sleeve is done and thus has the largest possible lever arm around Tilt sleeve.
- the inventive device or the method is not on a movable maintenance device but arranged or carried out stationary at a work station. They are here too To take advantage of the invention as described above. Instead of the im
- tapes 12, 13 is of course for the sleeve transport another means of transport, for example a single, wide band where the sleeve lies, can be used.
- Figures 7a to 7e show a representation with pneumatically operated stops.
- Figure 7a shows the basic position of a stop 4.
- the stop 4 is outside the center line l, on which the sleeves are conveyed. He's on one Pneumatic cylinder 8 attached. This cylinder 8 is substantially parallel to Center line l arranged.
- the pneumatic cylinder 8 is fastened to the pneumatic cylinder 85.
- the pneumatic cylinder 85 acts essentially at right angles to the center line 1.
- the left sleeve stopper is extended. It is shown schematically like the pneumatic cylinder 8 on a rod 86 of the pneumatic cylinder 85 is attached. For its part, the pneumatic cylinder 8 has the stop on a rod 80 4 arranged, which is also shown in the extended position. The The extended position is determined by pressurizing the pneumatic cylinder 8 or 85 causes. After the pneumatic cylinder 8 the stop 4 in this Has reached position, the pneumatic cylinder 8 is depressurized. So that will causes the approaching sleeve 2, as shown in Figure 7c, a damping Effect is experienced when it is promoted against the stop 4. This will make the Sleeve 2 damped so that it is on the sleeve conveyor belt, not shown remains. Due to the impulse of the transported sleeve 2, the pressure-free one is switched off Pneumatic cylinder 8 inserted.
- the pneumatic cylinder 8 which was first depressurized, is restored pressurized, thereby extending the rod 80.
- the one at the Rod 80 attached stop 4 thus pushes the sleeve 2 back into one predetermined position.
- This predetermined position is suitable for the others Takeover units on the robot.
- the Sleeve stopper moved back to its starting position, in which the rod 80 and the rod 86 are retracted.
- the sleeve conveyor belt runs until the Sleeve 2 is in its predetermined position according to Figure 7d.
- the pneumatic cylinder with a low pressure, e.g. 0.5 bar too press while the pneumatic cylinder is 6 Bar is charged.
- the lower pressure which the sleeve exerts on the cylinder can be chosen so that the sleeve does not falls off the conveyor belt.
