A cable depositing device for processing a plurality of cables includes at least one receiving transport band having a length and an entry end, a partition that extends above the upper driving strand of the receiving transport band along the length of the receiving transport band, and a swivel arm. The receiving transport band defines a cable entry region and includes an upper driving strand. The upper driving strand and the partition define two receiving and stretching regions on either side of the partition. The swivel arm is disposed in the cable entry region, defines a swivelling-out range and includes a cable gripper.

Cable depositing device

The conductor end to be worked is clamped behind the conductor end section (5) to be stripped and is held in its axial position. Subsequently a scanning arrangement displaceable relative to the free end in longitudinal direction of the conductor end section (5) is used to determine the free end of this conductor end section (5), then the cutting knives (12, 13) are advanced into cutting contact with the conductor end section (5) by a distance (x) corresponding to the severing and/or insulation stripping length previously determined from the end position, and after cutting off the requested layer by means of cutting knives (12, 13) the latter are used to push the cut-off layer towards the end, and this cut-off and/or insulation stripping process can be repeated once or several times with graduated cutting depths, if need be.

Appliance for cutting-off and/or stripping insulation

At least two transporting and take-off rollers (2, 2') interact for the gripping of a cable (1) to be transported. The axes of rotation (3, 3') of the transporting and take-off rollers are each rotatably arranged on a cantilever arm (7, 7') capable of swivelling together about a second turning axis (6) arranged on a turning platform (10) and running perpendicular to the former axis and parallel to a common straight line (5) connecting the said two rollers (2, 2'). At least one of the two transporting and take-off rollers (2, 2') is arranged laterally adjustable in relation to its distance (a) from the second transporting and take-off roller (7). Further, first drive devices (25) connected so that they can swivel together with the turning platform (10), are provided for driving the two transporting and take-off rollers (2, 2'). Second drive devices (16) drive-connected to the turning platform (10) are provided for obtaining a precisely defined rotational movement of the turning platform (10) about the first turning axis (4).

A cable-feeding and cable-changing apparatus, whereby a cable change can be performed in an optimized time manner in cable-processing machines which include a stationary pivotable gripper and treatment stations arranged within the pivotal range of a gripper. For this purpose, two cable feeders are provided which are arranged at an acute angle to each other in their cable transport direction and symmetrically to a main transport axis. Displaceable cable-stepping devices are provided between the two sets of belt drives and a v-shaped cable-guiding part is connected by a respective limb to the cable exit side of the cable feeders and the cable-stepping devices, wherein the intersection of the limbs coincides with the main transport axis. During a cable change, and before the retraction of the one cable by the one limb, the other cable is advanced to the intersection by the other limb.

Cable-feeding and cable-changing apparatus for a cable processing machine

The apparatus for infeeding a cable in a predetermined infeed direction to an automatic cable processing machine enables moving standard cables and cables of reduced wall thickness at high velocities between the drive surfaces of two revolvingly contacting or confronting drive belts of two belt drives. By separating a drive roller synchronously driven with respect to the two belt drives from the measurement drive roller of a cable length measurement device it is possible to vary the diameter and thus the peripheral velocity of such drive roller. Consequently, there can be continuously applied to the cable a tension between the belt drives and the drive roller in accordance with the direction of movement of the cable. This cable tension prevents dam-up of the cable at this region of the cable infeeding apparatus, precludes any possible lateral departure of the cable from the belt drives and affords an exact length measurement of cable sections of the cable.

An apparatus for fitting of grommets onto ends of electric cables. The shape of the grommet is independent of the manner in which it is fitted, by which it is pushed onto an electrical cable, and the characteristics of the electrical cable is not important for the exact positioning of the grommet. For this purpose, a conveying rail of a feed apparatus includes a buffer, in which the grommets are stored in correct position. In alignment with the axis of a vertical bore arranged below the first grommet in the buffer, a singling cylinder with a punch, which is movable up and down, is arranged above the conveying rail and a pivotable fitting cylinder with a grommet-receiving part positioned on a piston rod is arranged beneath the conveying rail, wherein the grommet is pushed by means of the punch through the vertical bore into the grommet-receiving part and the fitting cylinder is pivoted into a horizontal position. Pivotable gripper elements thereafter surround and hold the grommet-receiving part and are moved together with the piston rod against the cable, while the grommet is pushed onto the cable and its position thereon is assisted by an excess pressure that builds up in the grommet-receiving part.

Cable-bundling equipment for cable-processing machines, wherein, a first cable slack can be finally bundled and withdrawn already properly oriented, while the bundling operation for a second cable slack continues to proceed and is not interrupted when a faulty cable is ascertained, with this equipment including a rotatable cable receptacle unit having first and second bundle clamps, wherein the first bundle clamps are associated with the reception of fault-free cables and the second bundle clamps with the reception of faulty cables; a first gripper, pivotable into three operative settings, which, in the first operative setting takes the cable from a second gripper provided for cable transport; the cable in the second operative setting of the first gripper is transferred to a first bundle clamp, or in the third operative setting of the first gripper to a second bundle clamp; the cable end to be transferred to the respective bundle clamp being transported extending perpendicular to the direction of movement of the second gripper, while the other end, according to cable slack, is guided in a first or second channel of a cable trough extending parallel to the direction of movement of the second gripper.

Cable-bundling equipment for cable-processing machines

With the apparatus there can be cut an electrical cable in a minimum amount of time and the cable can have selectively different electrical insulation lengths stripped therefrom, without requiring exchange of the cutting and insulation stripping tool upon switching over to a different insulation stripping length and/or to a different cable cross-section. For this purpose, two respective insulation stripping blades are arranged at a predetermined fixed distance from a cutting blade in each of two cutter holders. The insulation stripping blades are shorter in length in relation to the length of the cutting blades by an amount such that during a first part of a work or working cycle only the cable is cut. A retraction drive retracts the cable ends from the cutting location through the desired insulation stripping length, whereafter, during a second part of the work cycle there is cut into the electrical insulation, and during a further retraction movement of the cable ends the insulation waste is pulled off with the insulation stripping blades closed.

The apparatus for transporting cable sections enables transporting the cable sections cyclically or intermittently along a cable section processing line by means of double grippers which grasp opposite ends of an associated cable section. These double grippers are arranged at a substantially uniform spacing from one another at the outer periphery of a transport element. The double grippers are rotationally mounted perpendicular to the direction of movement of the transport element and perpendicular to the lengthwise axis of the grasped opposite ends of the cable sections. At least at two locations of the transport element there are stationarily arranged gripper actuators for opening each closed double gripper which has been closed under the action of the force of an associated spring, once in order to receive an infed cable section, and once to release the finished-processed cable section. The opposite ends of each engaged cable section are moved past cable work stations and during a work cycle, after having previously centered the related double gripper, processed or fitted with a terminal. By incorporating a pivot device or a rotary device each double gripper together with the grasped cable section, can be latchably rotated about its axis of rotation through predetermined angles.

With this device for an automatic mounting of connector shells (5) and electric conductors, in each case, a connector shell (5) is mounted, with the aid of an industrial robot (1), onto both contact parts (8.1, 8.2) of an electrical conductor at the end of a cable-processing line. Each end of the electric conductors is gripped by the first double gripper (11) of an additional transfer module (40) and, in a mounting position (32), is transferred to a stationary gripper (20). Before this transfer, if the electric conductor is gripped by the first double gripper (11) alone, then the conductor shells are mounted onto the contact parts and the mounting force is tested. After the stationary gripper (20) takes over the electric conductor, the first double gripper carries out a reverse cycle motion into a transfer position (30) in order to grip a new electric conductor. At the same time, after the mounting pressure has been checked, the robot gripper of the industrial robot (1) mounts the connector shell (5) completely onto the contact part (8.1, 8.2) and the perfect mounting is determined by a checking of the withdrawal pressure. The electric conductor (8), equipped with the connector shell (5), is placed by a separating motion of the robot gripper (3) of the industrial robot (1) under the fixed separator element (18).

Method for automatically connecting electric conductors with contact

The method and the apparatus for the performance of the method for feeding cable into an automatic cable-processing machine allows to move normal cables (18) and cables of reduced wall thickness at high speeds. The cable (18) is driven by the driving surfaces (3.1, 8.1) of two belts, (3, 8), where the belts (3. 8) of two belt drives (b 1.2), roll off one another. The first belt drive (1) is stationary, while the second belt drive (2) is arranged to be parallel displaceable and disposed perpendicular to its driving surface (8.1). The second belt drive (2) can be pressed onto a laid-in cable (18) by at least one pneumatic piston-cylinder unit (24). In order to assure a clean passage of a cable (18) through the belt drives (1, 2), a cable clamping and tightening device (19) is arranged on the cable feed side (16), and a cable-clamping device (20) is arranged on the cable exit side (17). Thereby, the laid-in cable (18 ) is tightened and precisely aligned before the start of operations. The driving surface (8.1) of the displaceable belt drive (2) projects beyond the driving surface (3.1) of the stationary belt drive (1) and serves for the reception of a driving roller (21) of an adjustable cable length-measuring apparatus (22).

The invention method and device for the automatic mounting of connector shells (5) and electric conductors (8) discloses that connector shells (5) are put on with the aid of an industrial robot (1) onto the contact parts (8.1, 8.2) of an electric conductor (8). A gripper tool (4) of the industrial robot (1) is capable to grip simultaneously several connector shells (5). Each contact part (8.1, 8.2) of the electric conductor (8) is maintained in rest position by two independently controllable gripper pairs (11.1, 11.2) of a double gripper (11) at the end of a cable-processing line (9), after a centering module (19) has set the desired position of the contact parts (8.1, 8.2). Depending on the intended device, the two contact parts (8.1, 8.2) of the electric conductor (8) can be simultaneously equipped with connector shells (5) by respectively one industrial robot (1), or successively by only one single industrial robot (1), with the aid of a transfer module (10), coordinated to the double gripper (11) and rotating the rotatable electric conductor (8). The error-free put-on of the connector shells, as well as a withdrawal motion required for the testing of the perfect contact seat, are surveyed by sensors. The finished, plugged-together cable harnesses (13) are for example transferred by two industrial robots (1), in a stretched state, individually, to a transport device (14) adapted to the length of the cable harness (13).

Method for automatically connecting electrical conductors to contact

A device for the transporting of cable sections is provided where cables (19), with a length of up to about 10 meters, are transported step by step from processing station to processing station along a cable-processing line with a processing station disposed on the two sides of the cable-processing line. A cable (19), gripped on one side by a stationary gripper (15), is discharged with a cable feed device with the aid of an insertable deflector (49) into a receiver provision (11) for forming a cable bundle (20). The receiver device (11), with the cable bundle (20) on the one hand, and the two cable ends (21, 22) gripped by a gripper (18) on the other hand, are moving in a forward direction independent of each other cyclically in like fashion. The gripper (18) of a rotatably disposed transfer module (17) can be rotated during a transfer cycle by 180 degrees such that the two cable ends (21, 22) as desired can be directed toward one or toward a second side of the processing line. Instead of the conventionally required pair-wise provided processing stations for the processing of the two cable ends (21, 22), only one such station is sufficient, which is disposed either on one and/or on the second side of the processing line. The finished processed cable is discharged or pulled out of the transport container (1) at the end of the processing line.
