DESCRIPTION:
BRIEF SUMMARY
The invention relates to a system for arranging and binding an elongated object, especially a cable harness. The system has an arranging device with whose aid the harness is arranged in a layer which is ready for binding. In the case of the cable harness, this arranging device is a layout table which has holders for constructing the desired structure of the cable harness, especially at bending points and junctions which are provided, and on which the cables are laid together. A further component of the system is a binding device for making loops around said harness and binding it by means of a lace, which device consists of a loop guide and a closing device. The loop guide guides the lace, emerging for example from a supply magazine, around the object and to the closing device, which contains apparatuses for connecting the lace ends. In the prior art, on the one hand the binding device forms an independent unit (U.S. Pat. No. 4,337,934) and, on the other hand, the loop guide and the closing device are combined in one tool (EP-A-0,264,142, DE-U-8,913,514, DE-U-9,004,993) which is sorted out by the arranging device. A normal embodiment of the loop guide is tongs which are disposed at the front end of a binding tool, are opened for gripping around and releasing the harness, are closed for carrying out the binding process and contain suitable guide devices for the lace. These known systems have the disadvantage that the reproducibility of the positioning of the tool relative to the object which is to be bound and is located in the arranging device is not guaranteed. Looking for suitable binding points is, rather, left to the operating personnel; the bindings thus turn out differently. When binding cable harnesses it is also possible for the abovementioned holders preferably to be disposed at the bending and junction points of the cable harness which are provided, thus not allowing the loop guide to surround the cable harness at these points. Using the known tools, no bindings can thus be made where they would secure the structure of a cable harness particularly effectively. A further disadvantage of the known tools is that the required opening and closing of the same in order to surround the object with the loop guide necessitate complex movement control.
The invention is based on the object of providing a system of the type mentioned initially, which does not have these disadvantages or has them only to a relatively minor extent.
The solution according to the invention has at least a part of the loop guide disposed on the arranging device. It is often adequate to dispose only a part of the apparatuses, which are used for guiding the lace on the arranging device, while other parts of the same are disposed on the tool. In the following text and in the claims, the term loop guide is thus intended also to mean parts of the complete lace guide apparatus, to the extent that they are disposed on the arranging device.
For harnessing a group of elongated objects at a single point by means of an adhesive strip, it is known (FR-A-1,367,018) for a lower holding device for the harness and an upper feed device for the adhesive strip to be disposed one above the other in a fixed spatial assignment, the holding device and the feed device each being equipped with one half of a rotating guide for the holding device. At the start of the binding process, the lower half of the rotating guide is raised with the holding device to the upper half of the rotating guide and to the adhesive strip feed device. In the rotating guide, which is combined in this way, the holding device is rotated with the harness, and the adhesive strip is at the same time looped around the harness. It is furthermore known, for harnessing a group of relatively short elongated objects at a single point (U.S. Pat. No. 4,561,234) to provide under a stationary binding tool a conveyor device on which a multiplicity of harness holders are arranged which are fitted with the harnesses in front of the tool, are held in the tool position for binding and are emptied be
