ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to equipment for making up a cable, consisting of subassemblies for holding fast and processing the cable.
2. Discussion of the Prior Art
Automated machines or semi-automated machines are used for making up and processing cables, wherein in the case of semi-automated machines the cable feed is carried out automatically. The cable ends are mechanically stripped of insulation and subsequently a contact is connected with the cable end by crimping. The cable is laid in by hand and held by a gripper during the processing, wherein the cable is kept in the hand during the short processing time. Further processing steps, such as for example trimming and/or equipping with nozzles or sockets, can be done in similar manner.
The expensive insulation-stripping process and the qualitatively inadequate stripping of insulation from the cable end are unsatisfactory in the known equipment. Insulation which is not fully cut into makes difficult or impossible the following pulling-off step or insulation which is cut into too deeply has the consequence of damage of the conductor strands. Faulty crimp connections are not recognized. Moreover, the costly adjusting work in the case of converting the production equipment to different cables is disadvantageous.
SUMMARY OF THE INVENTION
Here the invention will provide a remedy. The invention meets the object of avoiding the disadvantages of the known equipment and of providing equipment, for making up cables, which improves the manufacture qualitatively and in terms of production. Pursuant to this object, and others which will become apparent hereafter, one aspect of the present invention resides in an apparatus for making up a cable, which includes a gripper unit for holding the cable fast during processing so that the cable is transportable to at least one processing region.
In another embodiment of the invention the gripper unit includes a guide module for guiding the cable and a gripper module with cable grippers for gripping the cable. The cable grippers include two drivable cable gripper jaws.
In another embodiment of the invention the gripper module is vertically displaceable for adaptation to a processing height and/or rotatable about an axis for transportation of the cable. The guide module includes guides for the vertical displacement of the gripper module and drive means for rotating the gripper module about the axis.
In still a further embodiment the apparatus includes a gripping device operative to vertically displace the gripper module and a force storage device that is operatively arranged to reset the gripper module. Preferably, the force storage device is a spring.
The advantages achieved by the invention are substantially to be seen in that the laying in of the cable is simplified and at the same time the triggering of the processing procedure is accelerated. It is further advantageous that faulty crimp connections are recognized and cut off. Moreover, several different processing steps can be carried out by the same subassembly, which in turn has a cost-reducing effect on the manufacturing costs of the production equipment.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of the disclosure. For a better understanding of the invention, its operating advantages, and specific objects attained by its use, reference should be had to the drawing and descriptive matter in which there are illustrated and described preferred embodiments of the invention.
