Definitions

  • the invention relates to a flexible transport system according to the features of the preamble of the first claim.
  • Such flexible transport systems basically have the advantage over fixed composite systems, for example between a spinning and a winding machine, that there are neither rigid transport routes, nor are there any restrictions with regard to intermediate storage, intermediate treatment or rigid coordination of the machine capacities.
  • Such a flexible transport system is known for example from the generic DE-OS 26 56 811.
  • trays for bobbins and bobbin tubes are placed on a transport carrier between textile machines of successive processing stages in yarn production, which can be designed, for example, as a carriage and can be moved on any transport routes.
  • a transport carrier has at least one support surface for the trays and has partitions for dividing the rows of trays within which they can slide. The transport carrier is first completely unloaded on the respective textile machine in order to then be fully loaded again. A different can be done by means of lifts Height level between the unloading and loading side.
  • Modern spinning machines or winding machines work with transport circuits for trays that carry cops or sleeves. In such textile machines, it is necessary to load and unload the known transport carrier at the same time.
  • the distance between the end of the partition walls and the end of the respective contact surface allows the trays to be moved transversely to the partition walls. This makes it possible to start unloading the transport carrier before the trays have to be moved along the partition walls. If the respective support surface on both sides of the dividing walls protrudes beyond the ends of the dividing walls by the amount corresponding to the tray width, after unloading a row of trays on the unloading side, the trays can be pushed through one division before the new trays are fed on the feed side is done. The inserted row of trays can then be unloaded beforehand. This means that two rows of trays can be unloaded on one support surface before the trays start to be fed to the transport carrier. With this system, intermediate storage of trays with cops or sleeves is not necessary when changing batches. The system is thus much more flexible than the known system.
  • the arrangement of support surfaces on several floors increases the transport capacity of the transport carrier many times over.
  • the use of lifts, particularly when using transport carriers with support surfaces on several floors, is not tied to their synchronous movement, as is the case, for example, in the solution according to EP 03 44 507 A1. Rather, the loading and unloading of the respective support surface can take place separately according to the present invention. All that is required is that the trays cannot be pushed along the partition walls until a row of trays on the unloading side has been removed beforehand.
  • the corresponding arrangement of lifts and stores in connection with the independent vertical movement of the lifts allows an almost continuous loading and unloading process of the textile machine. The required length of stay of the transport carrier on the respective textile machine can thus be minimized. In this way, the number of transport carriers required, for example, for a spinning complex can be minimized.
  • Bevels of the dividing walls on the loading side form leading edges for base-like elevations of the trays, which are required, for example, when the division of the trays by the dividing walls changes compared to the denser arrangement that results on the feed side without dividing walls.
  • the partition walls can be dimensioned such that they only guide the trays in this area.
  • the base plates with their outer lateral surface also meet in the area the partitions directly against each other, so that there is no difference in division.
  • FIG. 1 shows that a loading and unloading device 2 for trays 4 with cops 5 or sleeves 6 is arranged at the head end of a ring spinning machine 1 (not shown for reasons of clarity).
  • a transport carrier 3 which is designed here as an example, is inserted.
  • This transport carrier 3 consists of a frame 7, on which wheels 16 are attached. These wheels 16 are provided with locking means, but their representation has been omitted.
  • additional locking means such as bolts, locks and the like, are to be provided.
  • Such locking means are well known in mechanical engineering, which is why they are not shown in the drawings.
  • the contact surfaces 8 to 11 have partitions 12 to 15, between which the trays 4 can slide parallel to one another. These partitions 12 to 15 each end at a distance from the outer edges of the support surfaces, which corresponds to the diameter of a base plate of a tray 4. As a result, the bearing surfaces form slideways 8 ′ to 11 ′ on the loading side and 8 ′′ to 11 ′′ on the unloading side.
  • boundary edges (not shown here) on the outer sides of the contact surfaces 8 to 11. These boundary edges must be designed so flat that slide 22 to 25 can slide over them, but still have a sufficient contact area with the trays 4 when moving. However, it is also possible that these slides 22 to 25 guide the trays 4 on their base-like structure.
  • the ring spinning machine 1 Around the ring spinning machine 1, of which only a base 76 arranged at its head end is shown, runs a chain 72 which has drivers 73 at regular intervals which serve to guide the trays 4.
  • the trays 4 slide on slideways 77 and 78, respectively.
  • These slideways 77 and 78 of which only the front end is shown, run along the spindle rows of the ring spinning machine and are connected to one another at the rear end of the spinning machine.
  • trays 4 with sleeves 6, which are fed to the ring spinning machine on one side can also reach the spindles on the other side of the spinning machine.
  • the spindles At the time of the doffing process on the ring spinning machine, the spindles must consistently face trays 4 with empty sleeves 6. These are then exchanged for freshly spun cops 5.
  • the chain 72 which is deflected by chain wheels 74 and 75 and two further chain wheels, not shown here and located at the other end of the spinning machine, is driven by a motor 43 which drives the chain wheel 74.
  • This drive must be controlled very precisely in order to ensure that the trays 4 for the doffing process are exactly opposite the respective spindles, of which they are the new cops 5 should take over.
  • synchronization with the activity of the loading and unloading device 2 is required. Further details are given below.
  • the drivers 73 Due to the deflection of the chain 72 on the sprockets 74 and 75, the drivers 73 each open like a pair of pliers, which makes it possible to discharge or insert the trays 4.
  • the subsequent trays 4 move the trays already released along a further slideway 59 adjoining the slideway 77 in the direction of the transport carrier 3.
  • a stop 59 ' which may be coupled to a touch sensor (not shown), which immediately stops driving the motor 43 when it is energized.
  • a lift 48 can be positioned, whose capacity for trays 4 matches that of the slideway 59.
  • a row of trays 4 can be shifted from the slideway 59 directly onto the lift 48 by a slide 39 'of a shifting device 39.
  • This lift 48 is suspended on ropes 44 'and 45' which are wound on rope pulleys 44 and 45 when the lift 48 is moved upwards.
  • a motor 40 which acts on the cable pulley 44, is provided for driving the cable pulleys.
  • a connection, not shown, via a bevel gear shaft or a chain drive transmits this rotary movement to the rope pulley 45.
  • the ropes 44 'and 45' can be guided in guide rails 82, in which the fastening eyes for the ropes (not shown) are simultaneously guided slide on the lift. This provides safe lateral guidance of the lift 48.
  • the drive of the lift by means of a known spindle drive would be conceivable, but much more complex.
  • locks could be attached to the guide rails 82 at the respective floor height, which also act as switches and switch off the motor 40 when the elevator 48 arrives on the intended floor.
  • a slip clutch would have to be connected between the motor and the pulley 44, which slips when a predeterminable load is exceeded.
  • the locks / switches arranged on the respective floors are controlled by a central control unit 80, which will be described later, and have a feedback which reports the arrival of the lift on the intended floor to the central control unit.
  • the displacement device 39 is activated, controlled by the central control unit 80.
  • the slide 39 'moves a series of 7 trays 4 onto the lift 48.
  • the stroke of the slide 39 'can also be doubled for loading the conveyor belt 30.
  • this is only provided if the bottom floor of the transport carrier 3, the support surface 11, is to be loaded.
  • a prerequisite for pushing the trays 4 from the slideway 59 to the conveyor belt 30 is, of course, that this conveyor belt 30, in contrast to the illustration in FIG. 1, is already unloaded.
  • the conveyor belts 27 to 30 are fastened to a frame 26 via brackets 27 'to 30'. These brackets 27 'to 30' carry deflection rollers for the conveyor belts 27 to 30 at their two ends. Their upper edge projects above the upper trumes of these conveyor belts in order to form a stop for the trays 4 which are moved by the lift 48 onto the conveyor belts. Furthermore, all four conveyor belts 27 to 30 have edge reinforcements 27 ′′ to 30 ′′ on the side facing the lift 48. These edge reinforcements 27 ′′ to 30 ′′ are chamfered at least on the side facing the lift 48 in order to allow the trays 4 to slide on. The width of the conveyor belts 27 to 30 is chosen so that the trays 4 between the edge reinforcements 27 '' to 30 '' and the edges of the brackets 27 'to 30' with their base plates can be stable and horizontal and at the same time are securely guided.
  • the conveyor belts 27 to 30 each have two driver strips 31 to 34, which are attached at the same distance on the top of the conveyor belts. These carrier bars serve to move the trays arranged on the respective conveyor belt to the adjacent displacement area of the respective support surface of the transport carrier 3 arranged on this floor. Since the number of trays already moved in the transport carrier 3 increases the frictional resistance of these trays on the corresponding support surface also on the respective conveyor belt 27 to 30 the risk of sideways deflection of trays from the row increases. However, as already mentioned, this evasion is effectively prevented by the reinforcements 27 '' to 30 '' and the raised edges of the brackets 27 'to 30'.
  • the belts 27 to 30 are preferably driven separately on the side facing the transport carrier 30 by motors (not shown for reasons of clarity). These motors are also controlled by the central control unit 80.
  • hydraulic cylinders 18 to 21 Adjacent to the transport carrier 3, hydraulic cylinders 18 to 21, in which slides 22 to 25 are arranged to be longitudinally displaceable, are attached to a stand 17 at the level of the respective support surfaces 8 to 11. These hydraulic cylinders 18 to 21 are also controlled by the central control unit 80. A prerequisite for their operation is that the adjacent transverse displacement area of one of the support surfaces 8 'to 11' is fully occupied with trays 4 which are in the idle state. A further prerequisite is that the transverse displacement area of the same support surface arranged on the unloading side has already been emptied.
  • slidable slides 68 'to 71' are provided in pneumatic cylinders 68 to 71 on the unloading side. These slides 68 'to 71' have drivers 68 '' to 71 '' at their front ends. The slides 68 'to 71' are held against rotation in their respective pneumatic cylinders 68 to 71.
  • the pneumatic cylinders 68 to 71 are rotatably mounted within drive blocks 64 to 67. As shown in FIG. 2 using the example of the drive block 67, an output gear 86 is attached to the pneumatic cylinder 71, which meshes with a drive gear 87. This drive wheel 87 is driven by a motor 84.
  • a gear 87 ' is connected, which reduces the engine revolutions.
  • the motor is controlled by the central control unit 80 via a control line 84 'so that it can transmit a rotation of 90 degrees to the pneumatic cylinder 71 in each case.
  • Motor 84 is operated alternately in different directions.
  • valves 85 and 88 show, using the example of the pneumatic cylinder 71, that it can be actuated by valves 85 and 88. These valves are then connected to the central control unit 80 via control lines 85 'and 88'. Likewise conceivable, but not shown here, is the use of a reversing valve, which acts alternately on the two inputs of the pneumatic cylinder 71 with compressed air.
  • the slide 71 ′ which is held in the pneumatic cylinder in a manner secured against rotation, is also rotated by the same amount.
  • a driver 71 ′′ can assume a vertical position during the retraction of the transport carrier 3 (FIG. 3). This avoids a collision of the driver 71 ′′ with the first row of trays 4 while the transport carrier 3 is being moved into the loading and unloading device 2.
  • the central control unit 80 controls the motor 84, which rotates the pneumatic cylinder 71 with the slide 71 'by 90 degrees via the transmission 87', the drive wheel 87 and the driven wheel 86.
  • the driver 71 ′′ assumes a horizontal position. Since it is in its rearmost position, as can be seen from FIG. 1, the last row of trays can be moved along the transverse displacement region 11 ′′ from the support surface 11 onto a conveyor belt 53, which is aligned with this transverse displacement region 11 ′′.
  • the pneumatic cylinders 68 to 71 are also controlled by the central control unit 80. Since a control of the motors of the drive blocks 64 to 67 is also provided by the central control unit 80, it is ensured that the drivers 68 '' to 71 '' assume their horizontal position during the unloading activity of the slides 68 'to 71'.
  • the pneumatic cylinders and drive blocks are matched to one another in such a way that always when changing the direction of movement, the sliders are rotated by 90 degrees.
  • the drivers always assume a vertical position, while for unloading, that is to say before the slider is retracted, they are pivoted into a horizontal position. That’s it possible that during the movement of the slide to the right, the trays can already be moved on the respective support surface from the loading side to the unloading side. This is particularly important when the support surfaces are completely reloaded one after the other. This procedure requires a rapid sequence of all loading and unloading steps, which, as already mentioned, must all be coordinated with one another.
  • conveyor belts 50 to 53 arranged at the levels of the support surfaces 8 to 11 also form a buffer on the unloading side. These conveyor belts 50 to 53 are attached to a storage rack 99 (FIG. 3) via holders 50 'to 53'. These brackets each carry two pulleys of the conveyor belts.
  • a motor 42 acting on the front deflection roller is shown as an example in the conveyor belt 50.
  • the motors can be controlled by the central control unit 80 in such a way that they drive the conveyor belts as long as the assigned slide carries out its unloading activity.
  • the trays 4 are moved against an edge 50 ′′ to 53 ′′ arranged at the front end of the conveyor belts 50 to 53. This movement of the conveyor belts is intended to support the unloading activity and to avoid the escape of trays 4 from the row.
  • the two deflection rollers in each case can be rotated very smoothly and the conveyor belt is only driven by the displacement movement of the trays.
  • the conveyor belts are replaced by sliding surfaces, which is also possible within the scope of the invention, it would be advantageous to provide these sliding surfaces with guide edges on their long sides, similarly to the loading side, at least to the side of a lift 49 must be chamfered and flat to ensure unloading onto the lift without problems.
  • the individual conveyor belts 50 to 53 are unloaded onto the lift 49, analogously to the loading side, by means of slides 55 'to 58' which are actuated by hydraulic cylinders 55 to 58. These slides 55 'to 58' each shift a whole row of trays 4 transversely to their previous feed direction.
  • the hydraulic cylinders 55 to 58 are attached to a stand 54.
  • the slides 55 'to 58' are arranged between the upper runs of the conveyor belts 50 to 53 and the slides 68 'to 71'. While the drivers 68 ′′ to 71 ′′ act on the base-like structures of the trays 4, the slides 55 ′ to 58 ′ act on the base plates of the trays 4. This prevents mutual disability.
  • a limiting edge 81 is provided on the unloading side.
  • the support surfaces are provided with boundary edges on their entire circumference, in order to prevent the trays 4 from falling down, in particular during the transport of the transport carrier 3.
  • the boundary edges at the entrance opening on the loading side and at the exit opening on the unloading side would have to be removable or in the form of a barrier.
  • a guide edge 79 is provided in the transverse displacement area 11 ′′, opposite the boundary edge 81, which can consist of a slight step. This means that the transverse displacement area 11 ′′ is slightly lowered compared to the rest of the contact surface 11. Since it is only a minor paragraph, the trays 4 are pushed out of their The position between the partition walls 15 in this transverse displacement area 11 ′′ is only tilted very slightly, as a result of which the displacement process is not impaired. In addition, the trays 4 are still held by the T-shaped carriers while they are entering the displacement region 11 ′′.
  • the horizontal parts of the T-shaped partition walls 15 have inclined leading edges 15 '. These leading edges can be necessary if the division of the trays 4 in the transverse displacement area 11 'is smaller than in the area of the partition walls 15. This results from the fact that the partition walls keep the base plates of the trays 4 at a slight distance from one another. In contrast, the trays 4 with their base plates abut one another in the transverse displacement region 11 '.
  • the slide 25 On its contact surface with the trays 4, the slide 25 has a profiled shape adapted to the spacing of the trays, as a result of which the division of the trays into the individual guideways between the partition walls 15 is additionally supported. Analogous conditions exist for the support surfaces 8 to 10 arranged above the support surface 11.
  • the lift 49 is actuated analogously to the lift 48 by means of ropes 46 'and 47' which run onto rope pulleys 46 and 47.
  • a motor 41 drives the pulley 47, which is coupled to the pulley 46 via a bevel gear shaft or a chain drive.
  • Guide rails 83 ensure precise guidance of the lift 49.
  • the conveyor belt 60 like the conveyor belts 27 to 30, has two carrier strips 61 which are arranged at the same distance on the surface and which are intended to ensure reliable feeding of the trays 4 to the ring spinning machine.
  • a fixed boundary edge 62 and a reinforcement 62 'on the surface of the conveyor belt 60 here also ensure lateral guidance of the trays during the unloading of the conveyor belt 60.
  • the reinforcement 62' is again beveled at least on the side facing the lift 49 in order to be problem-free Ensure feeding.
  • the conveyor belt 60 is driven by a motor 91, which is actuated by the central control unit 80 via a control line 91 '.
  • the chain 72 'deflected by the sprockets 74 and 75 which represents a variant of the chain 72, has driver pins 73' which protrude into the transport path of the trays 4 through slits 77 'and 78' formed on both sides with boundary edges.
  • FIG. 3 in contrast to FIGS. 1 and 2, the level of the transport tracks on the ring spinning machine is arranged below the lowermost support surface 11 of the transport carrier 3. Out for this reason, additional hydraulic cylinders 89 and 98, which have slides 89 'and 98', are required.

  • 5 to 7 show variants of the design of lifts which are to be explained below using the example of the feed side.
  • 5 and 6 in two different working positions has two platforms 128 and 129, which, however, can be moved separately. They are operated by four drawstrings 142, 143, 146 and 147. These drawstrings are guided over belt rolls 142 ', 143', 146 'and 147', on which they are wound up during their upward movement. These belt rolls can be driven separately via shafts 142 ′′, 143 ′′, 146 ′′ and 147 ′′ by means of a gear 148.
  • This transmission has a motor 149. It is controlled by a central control unit 150 in order to convert the rotary movement introduced by the motor 149 into separate rotary movements of the shafts 142 ′′, 143 ′′, 146 ′′ and 147 ′′.
  • Platform 128 is attached to straps 143 and 146 by brackets 132 and 139.
  • This attachment can consist of a clamp connection, which can be released by means of a clamp screw, not shown, in order to be able to carry out a corresponding adjustment.
  • Sliding shoes 131 and 138 allow the platform 128 to slide along the belts 142 and 147. These belts 142 and 147 therefore only provide the platform 128 with a guide, by means of which the platform 128 is constantly held in a horizontal position.
  • the platform 129 is fastened to these two belts 142 and 147 by means of brackets 134 and 140, while it is only guided through the belts 143 and 146 by means of sliding shoes 135 and 141.
  • This mutual attachment to the belts allows the two platforms 128 and 129 to be actuated separately. Accordingly, the shafts 143 ′′ and 146 ′′ and 142 ′′ and 147 ′′ are driven synchronously.
  • the four belts are kept under constant tension by additional belt rolls 142 ''',143''', 146 ''and147'''.
  • the tape 142 is unwound from the tape roll 142 ', it is simultaneously removed from the Tape roll 142 ''', which is under spring action, rewound.
  • the band 142 like the other three bands, remains constantly tensioned.
  • the lower band rolls are all under appropriate spring action and are supported by corresponding shafts in bearing blocks 144 and 145.
  • the trays with cops 5 are fed by a conveyor belt 127, which receives the trays from the carriers 73 of the chain 72.
  • a pressure roller is at this height at the other end of the platform 136 arranged, which is supported by a roller holder 137.
  • FIG. 5 shows that the separate movement of the platforms 128 and 129 also allows the platforms 128 to be brought closer to one another in practice until they come into contact with one another. It should be noted, however, that loading of the lower platform 128 is only possible when the loaded upper platform 129 is already at a sufficient distance from the lower platform 128 in order to allow the unimpeded entry of cops 5 plugged onto the trays 4 between the two platforms to enable.
  • the upper platform 129 can be moved, for example, into one of the upper floors of the transport carrier 3, which has not been shown again here for reasons of clarity. Since the lower platform 128 is provided for the lower levels of the transport carrier, less time is required for the vertical movement. This ensures that the loading and unloading process runs smoothly, even if the lower platform 128 is inevitably fully loaded at a later time than the upper platform 129. In addition the lower platform 128 must have already arrived in the position below it again when the platform 129 is loaded again (FIG. 5). This lift, too, can advantageously be controlled with the lock / switch combinations already described on the respective floors, these being provided separately for each platform and being operable, for example, by the brackets 132 and 140.
  • stops 130 and 133 are arranged at the rear end of platforms 128 and 129, it can basically be dispensed with if a pressure roller 136 is used, which likewise reliably prevents the trays from being displaced beyond the end of the respective platform. It is also possible to provide a sensor on the roll holder 137 which detects the arrival of a tray at the end of the respective platform, reports it to the central control unit 150 and thus triggers the immediate stop of the subsequent delivery. In the normal case, however, it can be assumed that the trays, as already described, are only ever discharged in batches which correspond to the receiving capacity of a platform, which in turn is matched to the width of the receiving surfaces of the transport carrier.
  • FIG. 7 shows a further variant of a lift, in which two platforms 152 and 153 are firmly connected to one another via a frame 151.
  • the distance between the two platforms corresponds to that of the receiving surfaces of the transport carrier.
  • This variant is simplified compared to the one shown above in that the platforms can only be moved together.
  • Bands 156 through 159 are adjustably attached to the four corners of frame 151.
  • the belts 156 to 159 are guided over belt rollers 156 'to 159' which are driven via shafts 156 '' to 159 ''. They are arranged in a common gear 161, which receives its drive from a motor 160.
  • the shafts 156 '' to 159 '' are always driven synchronously. For this reason, it is also sufficient if there is a common return spring 163 which is attached to platform 152 and bracket 164.
  • several tension springs can also be arranged symmetrically.
  • the invention is not tied to the use of a specific type of lifts, stores and loading and unloading devices.
  • Central control units can be used to implement loading and unloading programs which are adapted to the particular intended use and the specific design of the textile machine, the loading and unloading device and the transport carrier.
  • Appropriate sensors must be used to monitor that all steps are graded accordingly.
  • the arrangement of stores and possibly also lifts with several, in particular separately movable platforms, increases the flexibility of the system so that the total loading and unloading time is considerably reduced.
  • the readiness for loading of a support surface can be monitored by completing the unloading stroke of a slide on the unloading side.
  • the readiness for receiving a support surface on the loading side according to FIG. 1 is given, for example, when the adjacent slide has completed the displacement of trays in the direction of the partition walls.
  • the central control unit receives a signal that this bearing surface is ready for loading again.
  • the unloading of the storage tapes onto the support surfaces can also be monitored accordingly.
  • a sensor can be provided, for example, which detects the arrival of a driver bar at the deflection point of the conveyor belt. The same applies to the unloading side, which is also the loading side for the ring spinning machine.
  • the central control unit provided can have a shift register which is matched to the loading capacity of a support surface. When completely replaced, this shift register blocks further loading and unloading processes for the respective contact surface.
  • the loading and unloading device was only explained in connection with a ring spinning machine in the exemplary embodiments, this device can also be used analogously on other textile machines, for example winding machines.
  • the timing which is present on the ring spinning machine by means of the chain 72 and the drivers 73 fastened to it at equal intervals, can be achieved in another transport system which does not have any positive guides for the trays by a stopper / sensor combination.
  • the passage of a predetermined number of trays is registered by the sensor and, after this number has been reached, the stopper prevents further transport of the following trays.
  • the respective support surfaces from the transport carrier for the loading and unloading process. These are advantageously provided at the height at which the transport system of the respective textile machine is arranged. In this case there is no need for lifts.
  • a lifting device can also be used according to the model of German patent application P 39 35 627.2, which vertically moves the transport carrier in its entirety. As a result, the individual contact surfaces can be set in succession to the height level of the loading and unloading device.
  • the essential advantage of the invention can be used in that rapid loading and unloading can take place without, for example, having to wait for the provision of trays when changing the batch before the loading and unloading process can be started.
