DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal crimping applicator automatic exchanging apparatus for automatically exchanging an applicator for crimping a terminal to an electric wire.

[0002]

2. Description of the Related Art As a terminal crimping apparatus for crimping a terminal to an electric wire, for example, a wire supplied from an electric wire supply reel is measured and cut to a predetermined length, and a covering portion at an end of the electric wire is peeled off. There is a device for crimping a terminal to the end of the wire.

When the type of the terminal to be crimped to the end of the electric wire is changed, it is necessary to replace a press die (applicator) or the like corresponding to the terminal to be crimped set in the press. In order to facilitate the replacement work, various types of automated apparatuses have been proposed.

[0004] That is, a plurality of movable mounting tables are arranged side by side in a predetermined direction at an appropriate interval on one side of the terminal crimping apparatus, and each of the movable mounting tables corresponds to a different type of terminal. While the applicator is mounted, each movable mounting table is reciprocally movable in the predetermined direction, and the moving operation moves the applicator on the movable mounting table positioned at the predetermined position to the set position below the press. It was configured to be transferred, set, and crimped the terminals.

When replacing the applicator, the applicator set at the set position is returned to the movable mounting table at the predetermined position, and then the desired applicator is mounted by the moving operation in the predetermined direction. The movable mounting table is positioned at the predetermined position, the applicator on the positioned movable mounting table is transferred to and set at a set position below the press, and different types of terminals are crimped.

[0006] As this type of terminal crimping applicator automatic exchanging apparatus, for example, apparatuses disclosed in Japanese Patent Application Laid-Open Nos. 61-99288 and 9-136199 are known.

[0007]

However, as disclosed in the above-mentioned Japanese Patent Application Laid-Open No. Hei 9-136199, when a plurality of movable mounting tables are reciprocated in a predetermined direction and positioned at a predetermined position corresponding to a press, each of the plurality of movable mounting tables is required. This is a moving method of moving the movable mounting table by an intermittent feeding method, and has a problem that it takes a long time to move the required movable mounting table to a predetermined position, resulting in poor efficiency.

On the other hand, as disclosed in Japanese Patent Application Laid-Open No. 61-99288, when a plurality of movable mounting tables are reciprocated in a predetermined direction and positioned at a predetermined position corresponding to a press, a rack and a pinion are used. If the moving method is such that the moving can be performed continuously, the moving time can be shortened. However, when identifying each movable mounting table and controlling the movement of the required movable mounting table to a predetermined position, if a servomotor is employed as a drive source, the origin must be adjusted each time power is supplied to the servomotor. Is required. The power to the servomotor is frequently turned off due to setup change, etc., but it is a wasteful time to move each movable mounting table in the reciprocating direction for each stroke in order to adjust the origin each time. And the problem of poor efficiency arises.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a terminal crimping applicator automatic exchanging apparatus capable of efficiently exchanging an applicator.

Space saving for installation can be achieved.

In addition, when the applicator unit 13 is transferred between the movable mounting table 17 and the mounting fixed table 23, the intermittent feed method is used in which the transfer is performed by reciprocating the locking member 26 two times. As the transfer cylinder 27, one having a short operating range can be adopted, and compactness can be achieved.

Further, in a state where the slide substrate 13a of the applicator unit 13 is transferred onto the mounting and fixing base 23, the slide substrate 13a is held in a fixed state by the stopper 23d and the lock piece 30. , The displacement of the applicator 13b in the terminal crimping operation or the like can be effectively prevented.

In the above embodiment, the automatic applicator changing device 14 has a structure having seven movable mounting tables 17, but the number of the movable mounting tables 17 may be increased or decreased as necessary. It is not limited to the number of embodiments.

In the above-described embodiment, the origin slitters 36a, 36b, 36c, 36d, 36e, and 3e are used as the detection unit and the identification unit, and the origin detector and the identification detector.
6f, 36g and identification slitters 34a, 34b, 34c,
34d, 34e, 34f, and 34g, and a structure using the origin photosensor 37 and the identification photosensor 35, the detection may be performed by a combination of limit switches or the like. Not limited.

[0067]

As described above, according to the terminal crimping applicator automatic exchanging apparatus of the present invention, the applicator moving means includes a screw shaft arranged along the horizontal direction below each movable mounting table, A nut body screwed to the screw shaft and fixed to the movable mounting table side, and a servomotor for driving the screw shaft to rotate forward and reverse, and each movable mounting table has a detection unit for detecting the origin of the servomotor. An identification unit for identifying each of the movable mounting tables is provided, and a detector for the origin and an identification unit for detecting the detection unit and the identification unit respectively provided on the movable mounting table located at the transfer position are provided. A detector is provided and when power is supplied to the servomotor,
The origin is adjusted by the detection of the detection unit by the origin detector, and the movable mounting table at the transfer position is identified by the detection of the identification unit by the identification detector. This has the advantage that the moving time can be shortened, the time required for origin adjustment can be shortened, and the applicator can be exchanged efficiently.

An applicator unit having an applicator is mounted on each movable mounting table, and each applicator unit is provided with a terminal supply reel for supplying a terminal to the applicator, and is mounted on the movable mounting table side. The terminal supply reel of the applied applicator unit and the terminal supply reel of the applicator unit transferred to the mounting fixed base are arranged in an overlapping manner in the reciprocating direction of each movable mounting base. This has the advantage that the installation space can be saved.
