Definitions

  • the invention relates to a method for cutting cables from a cable supply for processing the cable ends, in which the front cable end is first pushed into a certain intermediate position and then bent to form a loop and brought into a certain starting position, in which it points in the opposite direction to the feed and is held substantially parallel to the rear cable end with the same orientation as this, then the cable loop is enlarged to the predetermined length by a further cable feed and finally the rear cable end is cut off from the supply in a predetermined starting position.
  • the invention further relates to an apparatus for performing this method.
  • GB-A 2 049 500 It is also already known from GB-A 2 049 500 to provide a rotatable deflection device with two semicircular shaped bodies arranged at an interval between them, between which guide and clamping devices and a cutting device are arranged in order to form a cable loop.
  • the front cable end is first advanced by a feed device into a certain intermediate position next to a molded body.
  • the feed device stops while the front cable end is clamped and a loop is formed by rotating the deflection device by 180 ° by means of one of the shaped bodies.
  • the feed device is then switched on again in order to enlarge the loop to a certain size, and finally the cable is cut off at the rear end of the cable and the finished loop is transferred to the clamp holder for further transport.
  • the disadvantage of this method is that the conveying of the cable is stopped and started again with each work cycle.
  • the decelerations to standstill and the accelerations from a standstill cost a relatively long time, measured by the short cycle time, and cause slippage between the feed device and the cable, which affects the accuracy of the dimensioning of the cable length.
  • the invention is therefore based on the object of providing a method and a device of the type mentioned at the outset, in which precise positioning of the cable ends and also a relatively precise dimensioning of the cable length are achieved with simple means within a shorter cycle time.
  • the above object is achieved procedurally in that the cable is continuously advanced until it is cut off, the front cable end pushing against the stop in the intermediate position and thereby triggering the bending and the transfer into its starting position.
  • the new method has the advantage that the cable is continuously fed during each working cycle, so that optimally short cycle times are achieved. Slip is also minimized as there are no interruptions in the conveying movement.
  • a device which has a feed and length measuring device, a cutting device and a positioning device for inserting the cable ends into clamp holders, through which they can be transported to processing stations, the front cable end being rotatably supported by the feed device Swivel part can be advanced to a certain position and then the swivel part can be rotated with the front cable end so that it points with a directional component against the feed direction, and the cutting device is arranged between the feed device and the swivel part, which device differs from known designs, that the feed and length measuring device is followed by a guide channel for the cable, the rear part of which is viewed from the feed device and is arranged in the swivel part, which is preloaded by a spring and about 1 Is pivotable 80 ° as soon as it has been pivoted over a dead center by the front cable end pushing against a stop in the guide channel with the feed force. Even during the latter phase, the feed device runs continuously until the loop at the rear end of the cable is cut off.
  • the proposed construction has the advantage of an automatic mechanical functioning, without the need for monitoring and control devices which are susceptible to malfunction. It is not possible to position more precisely than with a simple stop, and furthermore there is no safer indicator for the correct moment of bending the cable by means of the swivel part than if it were advanced cable itself moves the swivel part over the dead center and thus starts the further swivel movement by means of spring force.
  • barbs In order to ensure that the front cable end remains in contact with the stop during the pivoting movement and thus reaches the predetermined starting position for further transport to the processing stations at the end of the pivoting movement, barbs, e.g. B. in the form of obliquely against the cable spring tongues attached, which prevent retraction of the cable in the guide channel.
  • the feed device consists of a pair of conveyor belts arranged in parallel, between which guide strips are arranged for lateral guidance of the cable. Following the guide strips, the mentioned guide channel then takes over the guiding of the cable during feed.
  • the guide strips and the parts with the guide channel should expediently be easily replaced or be adjustable in such a way that the clear cross section between the guide strips and in the guide channel can be adapted to the cable cross section being processed, so that each cable is guided with as little play as possible.
  • the cable ends should protrude more or less from the clamp holders that support them during processing.
  • This adaptation to the different manufacturing tasks can be achieved in an expedient embodiment of the invention in that on the one hand the length of the rear part of the guide channel can be changed by adjusting the stop or by changing the swivel part, and on the other hand the cutting device in the feed direction of the cable is adjustable on the front part of the guide channel is arranged.
  • the cable ends assume their starting positions when the rear cable end is cut off, in a further preferred embodiment of the invention they can at the same time be transferred essentially in the direction normal to the common plane of their central longitudinal axes to a conveyor element, from which they are then conveyed in their parallel position to the processing stations .
  • the guide channel behind the cutting device has a lowerable bottom with an opening, in the area of which the cable ends can be inserted into the clamp holders when the bottom is lowered.
  • the breakthrough in the area occupied by the rear cable end when the floor is lowered can be covered by a floor part that can be swiveled away laterally during the lowering.
  • the cable ends in the guide channel have a cross-sectional position predetermined by their cross-section, in which the wires in the cable lie in a certain way next to one another. So that the cable ends also reach the clamp holder in this predetermined cross-sectional position, it is provided in a further preferred embodiment of the invention that, before lowering the bottom of the guide channel, an upper tool part can be lowered, on which a knife of the cutting device and, via springs, several clamping plungers for pressing the cable are attached to the lowerable floor. Furthermore, actuating plungers for opening the clamp holders are preferably also attached to the upper part of the tool in order to perform as many functions as possible simultaneously with a single working stroke. Finally, this goal also serves the further preferred measure of attaching a control cam to the upper tool part, which cam cooperates with a guide roller connected to the laterally pivotable bottom part via a lever arm.
  • the wires In order to attach different terminals to the different wires, each with the color of their insulation, in the case of multi-core cables, the wires must be automatically located by means of electronic color detection and, if necessary, brought into a specific position for attaching the respectively assigned terminals.
  • electronic color detection there have been many malfunctions to date, which can be attributed to the talcum usually introduced between the cable sheath and the individual insulation wires, which is deposited in different thicknesses on the colored insulation of the wires and in some cases makes it impossible to carry out color detection at certain points. So far, attempts have been made with little success to shake off or wipe off the talc. However, it is usually too tight for this.
  • the wires are processed with rotating brushes at least one cable end after the removal of the cable sheath, the force of which acts essentially in the longitudinal direction on the wire ends.
  • a twisting that is to say essentially parallel alignment of the individual wires, is also achieved in a gentle manner.
  • the brushes preferably have cutouts on the circumference, so that the talc is also tapped off.
  • the cables hang in loops while the cable ends are being processed.
  • one of the two cable ends held by the conveying member is dropped and the other is transported so far that the cable is pulled over a shelf.
  • the procedure described above is suitable for cables and strands of all lengths if relatively short terminals or other parts are attached to the cable ends.
  • relatively long protective caps are used on relatively short cables, for example about 20 cm in length are to be applied.
  • the invention provides that the pivoting part remains in its initial position, in which the rear part of the guide channel is aligned with its front part, until the cable is cut off and transferred to a clamp holder, and the cable ends can be processed by machining stations arranged on opposite sides of the conveyor track of the clamp holders, it being possible for the cables to be axially displaceable by means of a gripper between two successively arranged machining stations but on opposite sides when the clamp holder is temporarily released.
  • z. B. protective caps which are to sit in the fully assembled state at one end of the cable, are pushed onto the cable from the other end of the cable.
  • a stop press 7 Shown for rotating and aligning the cable about its longitudinal axis, after which a stop press 7 follows, which strikes the terminals provided for this purpose at the end of the cable which will later be connected to an electrical device.
  • a twisting station 8 where the stranded wires of the wires are twisted at the other end of the cable, in order then to attach a plug bridge to the twisted wire ends in the subsequent station 9, the supply of which to the processing station 9 is indicated.
  • the next station 10 is a test station, and in the following stations 11 and 12 first an upper and then a lower half-shell of a plug is attached to the plug bridge and ultrasonically welded in the following processing station 13.
  • 14 is another test station, and then the ready-made cables are placed on a shelf 15.
  • the processing stations 11 to 14 are omitted or are switched off. Instead, several cable ends, to which a connector bridge is already attached and the connector housing is now to be injection molded, are gripped by a gripper 16 and transferred to a transfer device 17, which introduces these cable ends into a spray frame, not shown, where multiple connectors are then injected simultaneously will.

  • the spring 40 is arranged with respect to the axis of rotation 26 such that the spring force in the position of the swivel part 38 shown in FIG. 2 tends to rotate the swivel shaft 36 counterclockwise with respect to FIG. 2, so that the pivoting part 28 is held in contact with the guide block 24.
  • the pin 44 with the spring 40 passes through the dead center position, and then the spring 40 pulls the pivot shaft 36 with the pivot member 28 clockwise into that shown in FIGS. 3 and 4 position rotated by 180 ° .
  • a front cable end contained in the guide channel 34 in the pivoting part 28 is bent backwards, ie counter to the cable feed direction, so that a U-shaped cable loop is formed, which can be enlarged as desired by further cable feed by means of the conveyor belts 20, 22, as shown in FIG 3 is shown using the example of a cable loop 46.
  • a reversible pneumatic motor 48 is provided, on the output shaft (not shown) of which a crank 50 is mounted , on which a hook 52 is pivotally mounted eccentrically to the output shaft.

  • plungers 76 are attached to the tool upper part 58 via compression springs (not shown), which are intended to press the cable ends firmly against the base 30 according to FIG. 4 and thus hold them against displacement and twisting. Furthermore, two actuating plungers 78 with rollers 80 are attached to the upper part 58 of the tool, by means of which the clamp holders 56, as shown in FIG. 4, are opened.

  • the knife 82 is adjustable in the feed direction of the cable by means of a clamping bracket 84. Since the knife 82 penetrates the guide block 24, another guide block 24 also belongs to a different position of the knife 82. Depending on the position of the knife 82, there is a more or less large protrusion of the rear cable end designated by 86 over the gripping holder 56 The protrusion of the front cable end 88 over the clamp holder 56 engaging it is determined by the length of the guide channel in the swivel part 28.

  • the individual reference numbers 1 to 5 again refer to the same units as in the embodiment according to FIG. 1. Otherwise, 6 'means a stripping and twisting station, 7' a plug-in jumper stop station, 8 'a test station, 9' and 10 'assembly devices for a lower or upper connector half-shell, 11 'an ultrasonic welding station for connecting the connector half-shells and 12' a test station.
  • the cable part is manufactured which carries a plug at one end and is connected to the line switch at the other end.
  • the cable part which leads from the switch to the lamp is assembled.
  • 18 ' is a test station and 19' denotes a storage of the finished, switch-provided cables.
  • a system for the production of ignition cables with distributor and Ker zenstecker is shown.
  • the reference numerals 1, 2 and 3 have the same meaning as in the embodiment according to FIG. 1. Otherwise: 4 "a stop press for terminals, 5" a test device, 6 "a glycerine metering device, 7" an assembly station for straight distributor plugs, 8 "an assembly station for spark plug connectors, 9” an assembly station for angular distributor plugs that can be switched on as an alternative to station 7 ", 10" a swivel gripper, which detects two ignition cables at a time and transfers them to a circular conveyor with three workstations, 11 "representing two screwing stations, in which two plugs are screwed simultaneously, so that the cycle time can take eight seconds for a screwing process, for example, while the processing stations 2 to 9 “work with a cycle time of four seconds. Finally, 12 “denotes a test station.
  • the short ignition cable on the cutting and positioning device 2 is not bent into a loop and clamped with clamp ends 56 in both ends of the cable, but the swivel part 28 remains in the position according to FIG. 2, and the short cable is only on one End inserted in a clamp holder 56.
  • the clamped cable end is then fed to a stripping station 3 '' and a terminal impact press 4 ''.
  • An assembly station 5 "'follows in the processing step, where a candle plug with a protective cap is applied to the held cable end.
  • next work station 6' there is a gripper which, with the clamp holder 56 temporarily open, the cable in the longitudinal direction through the pliers mouth 110 pulls, after which the other end of the cable is clamped in the clamp holder 56.
  • the next following processing stations are arranged on the opposite side of the cable conveyor. It is an assembly station 7 "'for the pre-assembly of an angular distributor plug protective cap, a stripping station 8"', a terminal stop press 9 '"and an assembly station 10" "for assembly of the distributor plug.
  • a gripper then lifts the hanging end of the cable, which is fed to a test station 12'" and finally placed on a shelf 13 '".
  • the sequence of the processing stations described results from the fact that the last processed cable end is only stripped can, after the angle cap has been placed at the processing station 7 "'.
  • the exemplary embodiments show how variably the devices can be adapted to a wide variety of manufacturing tasks, since following the very quickly and precisely working cutting and positioning station 2, which brings the cables into an optimal position to be transported and processed, the following processing stations in each case the best possible location and mutual arrangement, easily accessible from both sides, easily detachable and replaceable can be attached to a rail, along which the cable holder carrying the cables are guided. It can also be seen that the cleaning and cleaning of the vein ends of talc by means of rotating brushes 116, the formation of the clamp holders 56, the arrangement of an accompanying conveyor 120 supporting the cable loops 46 and the methods and arrangements described in connection with Figs other types of devices for cable assembly can be used.
