Definitions

  • the invention relates to a device for feeding cables from a rotatingly drivable supply roll to an intermittently pulling cable assembly machine.
  • Buffer stores in the form of so-called dancer rolls are already known in the processing of threads, wires and tapes (cf. DE 30 13 203 A1), but these should also be used Sudden, violent pulling of cables under the conditions mentioned still accelerates the mass of the dancer rolls very much, with the result that the cable is also heavily stressed, different slippage occurs when measuring certain cable lengths and the conveyor elements attacking the cable quickly wear out.
  • the invention is therefore based on the object of creating a device of the type mentioned which, with relatively weak drives and simple means with only a small space requirement, ensures a trouble-free cable feed to the cable assembly machine.
  • the above object is achieved in that in the conveying direction of the cable behind the supply roll one after the other, the cable in the form of tensioned windings with variable circumference receiving the first buffer store, a controllable conveying device and a second buffer store loosely holding the cable.
  • buffer stores of different types and in the order given are combined with one another because, in cooperation, they mutually eliminate their specific disadvantages, because otherwise they would not have been possible for the application of interest here.
  • a buffer storage which loosely holds the cable for example in the form of a loop, can be used in the invention, since this only has one even in the case of long cable sections to be produced needs to have relatively small memory content.
  • a cable length is sufficient for this, despite the high take-off speed is only a fraction of the length of the cable sections to be produced.
  • the compensation takes place by means of the first buffer memory, which would be unsuitable as the sole intermediate memory for the reasons mentioned above, but which in connection with the second buffer memory can now bring out its specific advantages. It is able to store a sufficient length of cable in a small space in order to alternately dispense and resume several meters of cable if the consumer unplugs and stops cables of 6 m length, for example, at intervals of the order of 1-2 seconds. Since the cable is kept taut in the first buffer store, it can be guided precisely despite the high take-off speed and is prevented from being entangled.
  • the mass contained in the first buffer store is minimal in comparison to the storage drum, so that a weak, quickly accelerated drive for the controllable conveying device arranged between the first buffer store and the consumer is sufficient to pull cables out of the first buffer store just as or at least almost as quickly and to be delivered to the second buffer store as it is withdrawn from there by the consumer.
  • the low-mass controllable conveyor can be braked very quickly again when the consumer stops the cable pull abruptly, so that one can manage with a comparatively small loose cable length in the form of a single loosely hanging cable loop between the first buffer store and the consumer does not devour itself in front of the consumer at this point despite the whipping movement of the cable.
  • the first buffer storage in the manner of a pulley system consisting of two groups of rotatably mounted rollers with variable spacing between the groups.
  • the unit consisting of the last-mentioned group of rollers and the weight can be guided on a vertical guide of the stand.
  • the controllable conveying device can be set down from the first buffer store and can be arranged at an intermediate distance therefrom.
  • the controllable conveying device consists of one of the fixedly mounted rollers of the first buffer store and a cooperating, rotatable pressure element, for. B. a pressure roller or a pressed belt, at least one of these two parts pressed against each other can be driven.
  • the first buffer memory can store about 10 to 15 m of cable at a height of about 2 to 3 m, and this length can be controlled by the controllable conveyor if necessary can be quickly fed to the second buffer memory, which only needs to contain a cable length of about 1 to 2.5 m in the form of a loose, freely sagging cable loop. For such a short loop, lateral movement of the cable between vertical walls is sufficient despite violent movement. It is understood that the loose cable loop in the second buffer store can be shorter, the more precisely the controllable conveying device between the first and the second buffer store is coordinated with the conveying device of the consumer.
  • the invention offers the guarantee that the consumer conveyor, running at maximum acceleration and speed, can pull cables out of a loose loop in every phase.
  • the controllable conveying device between this loop and the first buffer store is also the time in which the cable conveyor device of the consumer is at a standstill for conveying cables from the first buffer store into the loop, so that, depending on the cable lengths required, the controllable conveyor device between the first Ideally, the buffer memory and the loop should run evenly, but in any case can be operated with gentler changes in speed, which do not lead to undesired voltage peaks at the output of the first buffer memory loading the cable.
  • the above-mentioned advantage of the buffer store proposed according to the invention can already be achieved if the controllable conveying device arranged behind it is controlled by means of a simple on / off control. You can see a finely adjustable speed control for the conveyor arranged behind the first buffer store, depending on the cable length to be manufactured and the available length of the cable loop in the second buffer store, the acceleration of the cable can be reduced to the minimum value to be calculated in each individual case and a completely uniform cable feed from the first Buffer memory in the cable loop of the second buffer memory are largely approximated.
  • the unwinding speed of the supply roll and / or the conveying speed of the conveying device behind the first buffer store is controlled as a function of the cable withdrawal speed of said or another consumer.
  • monitoring devices must also be provided as a rule, which monitor the cable supply in the first and second buffer storage and, if necessary, provide corrections in the cable feed depending on the storage filling.
  • an optimal control of the drive speed of the storage drum and of the conveying device arranged behind the first buffer store can therefore be dispensed with, calculated from the characteristic of the cable requirement of the consumer.
  • FIG. 1 shows a cable 10, which is fed from a supply roll 12 to a consumer 14, of which only one cable feed device 16, which can be driven by a controllable drive motor A, and a cutting device 18 are shown for the sake of simplicity.
  • the feed device 16 pushes a certain cable length through the cutting device 18 in each work cycle, where it is then cut off, in order to be subsequently processed further.
  • the order of magnitude of the cycle times and the cable sections was mentioned at the beginning. In order to achieve these values with great accuracy and as little stress on the cable as possible, it is provided in front of the feed device 16 in the form of a loosely hanging loop 20 and, in the example, via a deflection roller 22 of the feed device 16 is supplied.
  • the cable loop 20 should not be chosen too large, because otherwise not only an inappropriately large amount of space is required, but also the tensile force to be overcome by the feed device 16 increases.
  • a cable length in the loop 20 of approximately 1 to 2.5 m has proven to be expedient.
  • a buffer store Arranged in the conveying direction of the cable 10 in front of the cable loop 20 is a buffer store, designated overall by 24, for a cable length of approximately 8 to 15 m.
  • This buffer memory 24 consists of an upper roller group 26 mounted on a fixed common axis and a lower, coaxial roller group 28 hanging in the cable windings formed.
  • both roller groups 26 and 28 each consist of 3 of the same size, independently rotatable on the axis of the Roller group of mounted rollers, which are designated 30, 32 and 34 in the case of the upper roller group 26 shown in plan view in FIG. 3.
  • another roller 36 In addition to the upper roller group 26 there is another roller 36, which in the example is somewhat larger and is also mounted coaxially.
  • the rollers 30-36 are mounted on a stand 38 fixed to the floor, which on the side of the rollers with a vertical guide, not shown, for. B. in the form of a dovetail groove, in which a carriage, also not shown, is displaceable in the vertical direction, which is firmly connected to the axis on which the three rollers of the roller group 28 are rotatably mounted.
  • the mentioned carriage not only has a guiding function for the roller group 28, but also represents a weight load for the cable windings which are guided around the rollers of the roller groups 26 and 28.
  • the cable coming from the supply roll 12 is initially via the outermost upper roll 30 out, then runs down over the outermost lower roller of the roller group 28, up over the middle roller 32, down over the middle roller of the roller group 28, up over the roller 34, down again over the inner of the three rollers the roller group 28, back up over the larger roller 36 and from there to the cable loop 20.
  • the larger roller 36 of the upper, fixedly mounted roller group 26 is designed as part of a controllable conveying device, designated overall by 40. It consists of the roll 36 z. B. from one or more pressure rollers 42 or preferably a belt guided over a plurality of deflection rollers, which rests on a larger circumferential area against the circumference of the roller 36 under pressure, the cable 10 between the roller 36 and the pressure roller or rollers 42 or said belt or another pressure element and is driven frictionally in the conveying direction towards the cable loop 20.
  • the drive motor of the conveying device 40 designated B, can drive the roller 36, as shown in the example according to FIG. 1, but it can also, as indicated in FIG. 3, drive one of two pulleys, via which one is pressed against the roller 36 Driving belt runs.
  • the controllable conveyor 40 with its drive motor B simultaneously forms a backstop, which prevents cables from being pulled back from the loose cable loop 20 under the weight load by the roller group 28 and the guide carriage connected thereto into the buffer store 24.
  • this weight load is not sufficient to pull cables from the supply roll 12 when the drive motor C is stopped. Accordingly, only to the extent that the drive motor C drives the supply roll 12, the cable length unwound as a result of the weight load caused by the lower one Coil group 28 and its guide carriage pulled into the buffer store 24, while the cable length conveyed from the buffer store 24 into the cable loop 20 is determined by the control of the drive B of the conveyor device 40.
  • the cable length currently contained in the cable loop 20 is registered in the example by a plurality of light barriers 44 arranged one above the other and additionally by a contact 46 actuated at a maximum cable loop. B. be provided that whenever the lowermost light barrier 44 no longer registers the cable loop 20, the drive motor B of the conveyor device 40 starts up and its conveying speed is accelerated, the shorter the cable loop 20 as a result of the cable being pulled off by the feed device 14 is what is indicated by the fact that the higher light barriers 44 no longer register the cable loop.
  • the drive motor B of the conveyor device 40 thus runs at a different speed depending on which of the light barriers 44 arranged one above the other are currently responding, namely until the contact 46 is actuated when the maximum cable length in the loop 20 is reached and the drive B is thereby switched off.
  • light barriers or contacts 48 are mounted one above the other on the stator 38 of the buffer memory 24, the bottom light barrier or the bottom contact 48 corresponding in function to the contact 46.
  • the drive motor C of the supply roll 12 switches to an increasingly higher speed. Only when the lower roller group 28 or the guide carriage connected to it again reaches the lowest light barrier or the lowest contact 48, is the drive motor C switched off.
  • the running or conveying speeds of drives A, B and C are shown one above the other on the time axis.
  • the feed device 16 works with a cycle time of 1.5 seconds, whereby it stands still for about a quarter of this time. With gradual acceleration, braking and the conveying speed, high values are achieved because the conveyed cable consists of a short, i.e. H. light, loose cable loop 20 is pulled off.
  • the drive motor B of the conveyor 40 starts with a certain time delay compared to the drive motor A, namely only after the lowermost light barrier 44 has given the start signal.
  • the increase in the speed curve, i. H. the acceleration is less steep than in the case of the drive A.
  • the speed of the drive motor B oscillates between two speed levels and only returns to zero after a delay after the feed device 16 has been finally switched off.
  • stepless control of the drive motor B it can also run during the ongoing cable production at an essentially constant, average speed which only needs to be readjusted slightly when unpredictable accidents occur in the cable transport.
  • role groups 26 and 28 can each consist of fewer or more than three roles.
  • the number of rolls depends on the available height of the buffer memory 24 and on the desired memory content.
  • the current level of role group 28 can e.g. measure continuously with ultrasound so that a change upwards or downwards is detected immediately and thus the drive motor C of the supply roll 12 can be regulated.
