Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a printing method and apparatus for a plurality of electric wires. In addition, in this specification, a printing means the thing attached | subjected in order to identify the electric wire which is a character, a symbol, a mark etc. which are given to the electric wire surface.
[0002]
[Prior art]
For example, a wire harness used for wiring in an automobile is a bundle of a large number of electric wires, and each electric wire is printed for electric wire identification.
[0003]
Conventionally, the printing applied to the electric wire is performed at the time of manufacturing the electric wire, and the assembly of the wire harness is performed using the electric wire on which the printing has been performed in advance.
[0004]
However, preparing each of the pre-printed electric wires has the problem of increasing the types of electric wires and increasing the inventory.
[0005]
[Problems to be solved by the invention]
Therefore, in recent years, it has been considered to print a plurality of electric wires during the processing of the wire harness. This method has the advantage that it is possible to reduce the types of electric wires and the inventory because it is not necessary to prepare each of the electric wires that have been printed in advance.
[0006]
In order to print on a plurality of electric wires during the processing of the wire harness, it is only necessary to put a plurality of electric wires in a parallel state and to perform the printing, but there is a problem that the electric wires have bending flaws and the work is difficult. is there.
[0007]
An object of the present invention is to provide a printing method and apparatus for a plurality of electric wires that solve the above-described problems.
[0008]
[Means for Solving the Problems]
The method for printing on the plurality of electric wires according to the present invention is to fix the plurality of electric wires in a parallel state, and then correct these electric wires, and then form a wall between the arranged electric wires and at the outermost ends of the plurality of electric wires. In this state, printing is performed on a plurality of electric wires.
[0009]
Moreover, the printing device for a plurality of electric wires according to the present invention includes a fixing device that fixes the plurality of electric wires in a parallel state, comb teeth inserted between the plurality of electric wires and the outermost ends of the plurality of electric wires, and Printing is performed on a straightening comb device that moves in the longitudinal direction, a wall combing device that forms walls between the straightened wires and the outermost ends of the plurality of wires, and a plurality of wires located between the walls. And a printing unit.
[0010]
By adopting the printing method and apparatus for a plurality of electric wires as described above, printing on a plurality of electric wires can be easily performed. That is, since the plurality of electric wires are printed after the electric wires fixed in parallel are arranged, the printing on the plurality of electric wires can be reliably performed. In addition, since printing is performed in a state where a wall is formed between a plurality of electric wires, it is possible to prevent a printing mistake between the electric wires.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a state in which a plurality of electric wires 1 are connected in parallel to a connector 2 (usually a pressure contact connector is used), which is in the process of processing a wire harness.
[0012]
Hereinafter, the case where printing is performed on the plurality of electric wires 1 connected in parallel to the connector 2 as described above will be described in the order of steps.
[0013]
First, as shown in FIG. 2, the connector 2 is fixed to the fixing device 3. The fixing device 3 includes a connector receiving jig 3A and a connector pressing jig 3B. The connector 2 is set on the connector receiving jig 3A and the connector 2 set on the connector receiving jig 3 is connected to the connector pressing jig 3A. It will be held down by 3B. As a result, the plurality of electric wires 1 are fixed in parallel at predetermined positions.
[0014]
Next, as shown in FIG. 3, the straightening comb device 10 is inserted between the plurality of electric wires 1 located in the vicinity of the connector 2 and at the outermost ends of the plurality of electric wires . This straightening comb device 10 has comb teeth 11 inserted between the plurality of electric wires 1 and at the outermost ends of the plurality of electric wires, and is inserted from below the electric wires 1.
[0015]
Next, as shown in FIG. 4, the straightening comb device 10 is moved in the longitudinal direction of the electric wire 1. As a result, the electric wires 1 are bent and the wrinkles are corrected and straightened. That is, it is trimmed. When the straightening comb device 10 is moved in the longitudinal direction of the electric wire 1, it is preferable that the interval between the comb teeth 11 for applying tension to each electric wire 1 is substantially the same as the electric wire diameter.
In FIG. 4 and FIGS. 5 and 6 to be described later, illustration of the connector receiving jig 3A and the connector pressing jig 3B for fixing the connector 2 is omitted.
[0016]
Next, as shown in FIG. 5, the under plate 20 is positioned on the lower surface of each electric wire 1 that has been trimmed. The under plate 20 has a support portion 21 for supporting a plurality of electric wires 1 on the upper surface, and a comb-tooth receiving hole 22 for receiving a comb tooth 31 of a wall comb device 30 described later. It is. The support portion 21 is formed at a position corresponding to the gap between the plurality of electric wires 1 and the outermost ends of the plurality of electric wires .
[0017]
Next, as shown in FIG. 6, the comb teeth 31 of the wall comb-tooth device 30 are inserted into the comb-tooth receiving holes 22 of the under plate 20 in the direction of arrow A from the upper surface side of each electric wire 1. Thus, walls can be formed between the plurality of electric wires 1 and at the outermost ends of the plurality of electric wires, and the plurality of electric wires 1 can be fixed. A printing hole 32 is provided at a position corresponding to the electric wire 1 on the upper surface of the wall comb device 30.
[0018]
Finally, the printing unit 40 shown in FIG. 6 is positioned on the upper surface portion of the wall comb-tooth device 30, and printing is collectively performed on the plurality of electric wires 1 positioned between the comb teeth 31 through the printing holes 32. Apply. As the printing unit 40, a commercially available printing device using a laser beam can be used. Note that printing is usually performed on all of the plurality of electric wires 1 positioned between the comb teeth 31, but depending on the case, not all of the plurality of electric wires 1 positioned between the comb teeth 31, but an arbitrary plurality of wires. Also good.
[0019]
In the above-described embodiment, the case where the present invention is applied to a plurality of electric wires connected in parallel to the connector has been described. However, the present invention can be similarly applied to a plurality of electric wires that are not connected to the connector.
[0020]
Further, the fixing device for fixing the plurality of electric wires in a parallel state is not limited to the connector receiving jig and the connector pressing jig as in the embodiment, and for example, a clamp member having a shape for holding the electric wires may be used.
[0021]
Further, the straightening comb device 10 may be inserted between the plurality of wires and the outermost ends of the plurality of wires from above the parallel wires.
[0022]
In the above embodiment, the under plate is used. However, the under plate can be omitted.
[0023]
As described above, according to the present invention, since the plurality of electric wires fixed in parallel are arranged and then the plurality of electric wires are printed, it is possible to reliably perform the printing on the electric wires, and between the plurality of electric wires and Since printing is performed in a state where walls are formed at the outermost ends of the plurality of electric wires, there is an advantage that troubles of printing mistakes between the plurality of electric wires can be prevented.
