Definitions

  • the invention relates to a device for generating different lengths of electrical cables to be unrolled from supply spools in the manufacture of cable branches consisting of several cables for the subsequent end contacting with electrical connectors for producing electrical cable connections, with a driven transport roller, across which the cables of the cable branch cross are guided parallel to each other to the axis of the transport roller, with the cables, in each case assigned, freely rotatable pressure rollers for the transport of the respective cable, if this is guided between the transport roller and the pressure roller lying against it, and with the control devices, which are respectively assigned and can be operated independently of one another for lifting the respective pressure roller from the transport roller and thus interrupting the transport of the respective cable, the predetermined cable length depending on the circulation of the transport roller starts.
  • the device consists of a transport roller which can be driven by an electric motor and via which the cables of the cable harness are guided parallel to one another.
  • the cables are each assigned a freely rotatable pressure roller, which is used to transport the respective cable when it is guided between the transport roller and the pressure roller lying against it.
  • the pressure rollers are each arranged on levers which can be pivoted by means of piston / cylinder units such that when the pressure roller is lifted off, the transport of the associated cable is interrupted in one pivoting position of the lever, while in the other lever position the pressure roller on the Transport roller rests and the cable located between them is transported.
  • the piston / cylinder units can be actuated independently of one another and the respectively predetermined cable length depends on the circulation of the transport roller.
  • the process sequence for generating the different lengths of the electrical cables is disadvantageous.
  • the pressure roller lies against the conductor that has the greatest length.
  • the electric motor for the transport roller is then switched on and runs until the conductor is advanced by a length which corresponds to the difference between this largest cable length and the second largest cable length.
  • the electric motor for the transport roller is switched off in order to then press the next pressure roller onto the cable with the second largest length using the corresponding piston / cylinder unit.
  • the electric motor for the transport roller is then switched on again and the process repeats itself until the cable with the shortest length.
  • This cable branch production which works discontinuously due to the intermediate stops, is time-consuming and therefore uneconomical.
  • the object of the invention is to further develop the known device in such a way that an improved process sequence for generating the different lengths of the electrical cables is possible.
  • the invention proposes that the transport roller can be driven continuously and that at the beginning of the cable branch production all pressure rollers are in the transport position in order to lift them one after the other when the predetermined cable length is reached to interrupt the further transport of the respective cable.
  • the transport roller is preferably driven by a servo or stepper motor. In this way, the corresponding cable can be transported to a predetermined length very easily by means of the transport roller control.
  • transport roller it is proposed that a plurality of transport rollers arranged one behind the other are provided, via which the cables of the cable branch are guided alternately, with each transport roller being assigned pressure rollers with associated control devices for the corresponding cables.
  • Two transport rollers are preferably provided, in a further development the transport rollers have the same diameter and preferably run at the same peripheral speed.
  • the use of several transport rollers has the advantage that electrical connectors with a narrow pitch of, for example, 2 mm can be contacted with the cables of different lengths following the device according to the invention, although the devices of the device according to the invention for producing the different lengths have a width, which is larger than the grid spacing, for example more than 2 mm.
  • the first, third, fifth etc. cable of the cable branch is guided over the one transport roller and the second, fourth, sixth etc. cable of the cable branch over the other transport roller, so that for the width of the corresponding devices for the generation of the different lengths of the corresponding cables remains twice the grid width. With three transport rollers, the width can be tripled accordingly.
  • the pressure rollers are each mounted on a pivotable about a common shaft Pressure lever arranged on which the associated control device acts.
  • the pressure rollers can be lifted from the transport roller in a technically very simple manner, in that the pressure lever is correspondingly pivoted by means of the control device and thus the pressure of the pressure rollers on the transport roller is interrupted.
  • a spring acts on each pressure lever, which presses the pressure lever and thus the associated pressure roller against the transport roller. Without actuation of the control device, when it is in the basic position, the spring thus presses the corresponding pressure lever into the working and thus into the transport position for the respective cable. To lift the pressure roller, only the control device then has to be actuated. If this is switched off again or returned to the basic position, the spring moves the pressure lever and thus the pressure roller back into the transport position.
  • the pressure levers are each designed with two arms with respect to the shaft, the pressure roller being arranged on one lever arm and a braking device being arranged on the other lever arm, which fixes the respective cable when the pressure roller is lifted off.
  • the brake is thus simultaneously actuated, which holds the corresponding cable in the position reached.
  • the braking device preferably has a spring-loaded braking element arranged on the pressure lever, which can be a spring-loaded pressure pin, for example. Since that Brake element is spring-loaded, a substantially constant braking force is exerted on the respective cable, which is independent of the pivoting position of the pressure lever. Damage to the cable is therefore excluded by the braking device.
  • a brake shoe which can be pivoted on the housing of the device is arranged between the brake element and the associated cable. This brake shoe improves the braking properties of the braking device and can be optimally set up for the cable.
  • pivotable pawls are provided for fixing the pressure levers in each case by snapping them into the raised position of the pressure rollers.
  • the pawls ensure that the pressure rollers are held in this raised position.
  • control devices In a constructive configuration of the control devices, they each consist of a lever which interacts with the respective pressure lever by means of an actuating cam and can be pivoted about a common lever shaft. Pneumatically actuated cylinder / piston units are provided for the pivoting movement of the levers. This represents a structurally simple possibility for pivoting the levers carrying the pressure rollers.
  • control devices for the lifting movements of the pressure rollers from the transport roller are arranged on a common moving device which, together with the control devices, can be moved into a position in which, despite actuation of the Control devices for lifting the pressure rollers, these cannot be lifted off.
  • This has the advantage that when the traversing device moves back into the starting position and when the control devices are acted upon, the corresponding pressure rollers are lifted at the same time, while the pressure rollers with unactuated control devices remain in their transport positions adjacent to the transport roller and continue to transport the corresponding cables. This makes it possible for several cables to have exactly the same length in a cable branch without length differences occurring within this very specific length.
  • the actuating device is preferably actuated by means of an eccentric shaft which can be actuated by a pneumatic cylinder / piston unit.
  • the device for generating different cable lengths in the manufacture of cable branches 2 consisting of several cables 1 consists of a frame 3 of a housing. As can be seen in FIG. 2, a shaft 4 is fixedly arranged between two frame parts of the frame 3. On this shaft 4, according to the number of cables 1, two-armed pressure levers 5, which can be pivoted next to one another, are supported, each cable 1 of the cable branch 2 being assigned a pressure lever 5. Each of these pressure lever 5 carries on a lever arm 5 'a freely rotatable pressure roller 6th
  • This transport roller 7 is driven by means of a servo or stepper motor.
  • the cables 1 are each guided between the pressure roller 6 assigned to them and the transport roller 7.
  • the cables 1 are guided over a table 9 of the housing lying thereon.
  • a spring 10 is arranged in the form of a compression spring, which tries to pivot the pressure lever 5 clockwise and thereby presses the corresponding pressure roller 6 against the transport roller 7 with the corresponding cable 1 arranged therebetween.
  • a braking device 11 On this lever arm 5 ⁇ of the pressure lever 5, a braking device 11 is also arranged. This consists of a brake pin 12 mounted in the pressure lever 5, which is pressed down by means of a spring 13 and is supported on a brake shoe 14, between which and the table 9 of the housing the corresponding cable 1 of the cable branch 2 runs. This brake shoe 14 is pivotally mounted.
  • a guide shaft 15 is arranged, which is responsible for the lateral guidance of the pressure levers 5. Furthermore, a pivotable pawl 16 is arranged behind the pressure levers 5 in the region of the lever arm 5 ⁇ on the left in the drawing, a compression spring 17 arranged between the housing and the pawl 16 trying to pivot the pawl 16 clockwise in order to be in a recess 18 in Lever arm 5 ⁇ of the pressure lever 5 engage.
  • a pneumatically actuated cylinder / piston unit 19 by means of which a shaft 20 for the pawls 16 can be pivoted, serves to pivot the pawl 16 back from the latching position into the starting position shown in FIG. This shaft 20 carries driver pins 21 which engage in corresponding recesses in the pawl 16.
  • Control devices 22 for pivoting the pressure lever 5 are arranged above the lever arms 5 ⁇ of the pressure lever 5. These control devices 22 are on a common one Process device 23 is arranged, which consists of two slides 24, between which a common for all control devices 22 lever shaft 25 is fixed. The slides 24 are operatively connected to an eccentric shaft 26 which can be actuated by means of a cylinder / piston unit 27 and which can be moved up and down.
  • levers 28 are pivotably mounted on the lever shaft 25. These each have actuating cams 29 which each engage the lever arms 5 ⁇ of the pressure lever 5.
  • Pneumatically actuated cylinder / piston units 30 are used to pivot the levers 28, each of which engages at the free end of the levers 28. These cylinder / piston units 30 are carried by cylinder shafts 31, which are mounted between the slides 24.
  • the cables 1 are unrolled from supply spools and fed parallel to each other in one guide track of the device, each of the cables 1 being passed between the pressure roller 6 assigned to it and the transport roller 7 common to all cables 1.
  • the device is in the position shown in Fig. 1, i.e. the pressure rollers 6 are pressed against the transport roller 7 by the springs 10 assigned to them. Since this is driven by the servo or stepper motor, the respective cable 1 is transported.
  • the corresponding pressure lever 5 is pivoted to interrupt the further transport of this cable 1.
  • the corresponding cylinder / piston unit 30 is pressurized with air, so that the associated lever 28 is pivoted about the lever shaft 25, as shown in FIG. 3.
  • the actuating cam 29 of the lever 28 presses the lever arm 5 ⁇ of the pressure lever 5 downward, so that the pressure roller 6 lifts off the transport roller 7 and the further transport of the cable 1 is interrupted.
  • the brake pin 12 is moved downwards by the spring 13 and moved onto the brake shoe 14, so that the cable 1 is clamped between the latter and the table 9 of the housing for fixing it.
  • the cable 1 with its desired length can now be cut off and sent for further processing.
  • Fig. 3 it can also be seen that when the pressure roller 6 is raised, the pawl 16 engages in the recess 18 in the pressure lever 5 due to the force of the compression spring 17. As a result, the pressure lever 5 is held securely in its raised position.
  • all the pressure rollers 6 must be brought back into the pressing position on the transport roller 7.
  • the levers 28 are pivoted back into their starting position and, by actuating the cylinder / piston unit 19, the shaft 20 is pivoted such that the driving pins 21 pivot the pawls 16 to the left, so that the pressure levers 5 are released.
  • the slide 24 is moved upwards by means of the cylinder / piston unit 27 via the eccentric shaft 26, as shown in FIG. 4.
  • the corresponding levers 28 with their cylinder / piston units 30 are pivoted into the supposed lifting position for the pressure rollers 6.
  • the levers 28 remain in their initial positions, as shown in FIG. 1.
  • the levers 28 with their actuating cams 29 are in the position in which the pressure levers 5 could be pressed down, but due to the raised position they are outside the effective range.
  • FIG. 5 shows a modified embodiment of the device for producing different cable lengths shown in FIGS. 1 to 4.
  • the difference is that instead of using only a single transport roller 7 in this embodiment, two transport rollers 7 are provided and these are arranged one behind the other, as can be seen in FIG. 5.
  • the parallel cables 1 of the cable branch 2 are guided over both transport rollers 7 in such a way that the first, third, fifth etc. cables 1 are each assigned a device for generating the different cable lengths, which interacts with the one transport roller 7, and that second, fourth, sixth etc. cable 1 is assigned a device behind it for generating the different cable lengths, which interacts with the other transport roller 7, so that the one transport roller 7 has the devices for generating the different cable lengths for the first, third, fifth etc.
  • cables 1 of the cable branch 2 and the other transport roller 7 are assigned the devices for generating the different cable lengths for the second, fourth, sixth etc. cables 1 of the cable branch 2, so that essentially twice the grid width can be provided for these devices, without having a side space problem e there.
