Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an automatic wiring apparatus equipped with a wire breakage detector for detecting wire breakage during cable harness wiring.

Computers and automatic telephone exchanges are equipped with a large number of wires to connect various devices, and a cable harness is a group of wires formed into various patterns and tied together in a suitable place.

As the size of the equipment increases, this cable harness requires the use of a huge number of conductors.As a result, it takes a considerable amount of time to do this wiring by hand, and incorrect wiring can occur in the completed cable harness. This easily occurs, and it takes a great deal of effort and time to correct it.

Therefore, in recent years, some automatic wiring apparatuses have been devised and put into practice that automatically form the cable harness on a work table.

As shown in Fig. 1, this automatic wiring device includes a control box 1 that inputs magnetic tape or perforated tape recording the wiring pattern of the cable harness and exchanges it into electrical signals to control the operation of each mechanism. A wire storage cart 4 carrying a large number of wire supply reels 3 wound with various wires 2 for automatic wiring, and pins 5 corresponding to the cable harness pattern are arranged in advance, and set on a work table 6. a separate wiring board 7, a beam 8 that is slidable by a linear motor along the longitudinal direction on the work table 6, and a beam 8 that is slidably arranged on the beam 8 by an air motor and vertically There is also a movable wiring head 9, and various wires 2, 2... whose ends are fixed to the work table 6.
and the parking par 1 of the vertical frame 10.
It consists of feeders 12, 12, . . . moored on top of the feeder 1.

In this configuration, the wiring head 9 is connected to a plurality of feeders 12 moored on the parking park 11 of the vertical frame 10 according to control signals from the control box 1.
．． Select only one from 12... and keep it,
By traveling along a predetermined route over the separate wiring board 7, the wire 2 suspended from the feeder 12 is engaged with the pin 5 of the separate wiring board 7, thereby performing wiring.

By the way, if excessive tension is applied to the wires and the wires break during the wiring of the cable harness, there will be a huge number of wires, and it will be extremely difficult to find them after forming the cable harness. It took a long time.

Therefore, this idea was created in view of the above problems.
The present invention provides an automatic wiring device that is equipped with a wire breakage detector, applies current to various wires to form an electrical loop, and detects wire breaks during cable harness wiring. be.

An embodiment of this invention will be described below with reference to the drawings.

FIG. 2 is an explanatory diagram showing an embodiment of detecting a line break in the automatic wiring apparatus shown in FIG. 1 using the line break detector according to the present invention.

In the figure, a large number of wire supply reels 3, 3... are placed on a wire storage cart 4, and the wire 2 wound on these wire supply reels 3, 3... After passing through an unwinding device 3b that prevents bending, it is introduced into and suspended by a tension control 13 disposed on a vertical frame 10, and further includes an excessive tension detection mechanism 14 consisting of a microswitch, a reel, etc. The capstan 12a, which is rotatably provided inside the feeder 12, is introduced into the feeder 12 moored on the parking parlor 11 through the wire guide 15, which is a semicircular bush.
It is sent out downward from the guide tube 12b, and its tip 2a is fixed to the work table 6 while being electrically connected to the work table 6 by, for example, soldering or screwing.

Reference numeral 16 denotes an automatic wiring device having the above configuration, in which current is applied to various wires 2, 2, .
The address signal corresponding to ``line breakage detection signal'' is
This is a line breakage detector that sends out data to the control box 1, and is composed of an OR gate 17 and a gate circuit 18.

The base ends 3a of the wires 2, 2, . . . wound on the wire supply reels 3, 3, .
, 2... are all grounded.

The input terminals a, b, . Even if the wire is disconnected, the output of the OR gate 11 becomes logic "1" and is introduced into the input terminal of the gate circuit 18, and the gate circuits 1 and 8
will be opened.

On the other hand, an address signal corresponding to the wiring head 9 during wiring is constantly supplied to the input terminal ◎ of the gate circuit 18 from the control box 1, and when the gate circuit 18 is opened, this address signal is It is supplied to the control box 1 as a "line breakage detection signal".

That is, since a break in the wire 2 occurs when the wire 2 is being wired, it is possible to know which wire 2 is broken based on the address signal at this time.

Further, when the control box 1 is supplied with a "wire breakage detection signal" from the wire breakage detector 16, it interrupts the wiring operation and displays which wire 2 is broken.

As is clear from the above description, the automatic wiring device of this invention reliably supplies current to the wires by energizing multiple wire supply reels and pins for fixing the ends of multiple wires. A wire breakage detector is provided to form an electrical loop and detect wire breakage.
Since it is possible to immediately detect wire breaks during cable harness wiring, it is possible to omit the conventional wire breakage check test after forming cable harnesses, greatly improving work efficiency, and making it possible to prevent wires from being wound on reels. Even if the wire used up is used up, the detector's electrical loop is broken, so it can be detected in the same way as a wire breakage, and unmanned operation is also possible.
