After the marking is completed, the marker 1
Is returned horizontally by the restoring force of the tension spring 18 of the holder 3, the parallel link 7 is returned backward by the rod compression operation of the cap removal cylinder 8, and the cap part 6 is attached to the tip of the marking. And markers of different colors (1 ₁
In order to position (1 ₂ -1 ₄ ) on the work receiving table 10, the selection rotary cylinder 5 is operated to move the slider 4, the holder 3 and the marker 1 integrally.

FIGS. 5 to 7 show a second embodiment of the marking device according to the present invention. This apparatus holds a plurality of (four) markers 51 in parallel in the horizontal direction, and a holder 54 having a pair of rollers 52, 53 arranged side by side in the marker longitudinal direction, and a pair of rollers 52, 53. A vertical swing plate 56 having a guide groove 55 formed by linking a straight portion 55a and an upward curved portion 55b from the front to the rear, and a cap portion 57 protruding forward and fixed to the plate 56. A horizontal linear cylinder 59 for marking, which moves the holder 54 along the guide groove 55 by pressing the holder 54 with a reciprocating rod 58 in the guide groove 55, and the swing plate 56 via a slider 60 in the orthogonal direction. A pair of long and short horizontal cylinder cylinders 61 and 62 for selecting markers, which are moved in the direction in which the markers are arranged, and a horizontal work support 63 arranged in the swinging direction of the markers 51. Generally composed of Ri.

The holder 54 has a cylindrical holding portion 65 into which a rear portion of the marker 51 is inserted and fixed with a thumbscrew 64, a rear end of the holding portion 65 is fixed downward, and a pair of the front and rear rollers 52 , 53 are a pair of left and right side plates 66 having a substantially inverted trapezoidal shape.
a and 66a, are integrally supported by a shaft 67 of the front roller 52, and are rotatably installed in front of the moving unit 66 so as to be rotatable.
And a joint portion 68 (FIGS. 5 and 6) connected to the first portion. The holder 54 is provided in parallel for each marker. When the marker is not used, the pair of rollers 52, 53 is positioned within the straight portion 55a of the guide groove 55 of the swinging plate 56 to support the marker 51 horizontally.

The oscillating plate 56 fixes the marking cylinder 59 horizontally at the front end thereof.
Of the reciprocating rod 58 can enter the straight portion 55a of the guide groove 55. The guide groove 55 forms a horizontal straight portion 55 a having a length substantially the same as the length in the front-rear direction of the moving portion 66 from the front end of the swing plate 56, and the straight portion 5 a.
Upward curved portion 55b from 5a to the rear end of the plate
Is formed. The swing plate 56
The cap portion 57 is fixed in front of the cap via a horizontal protruding plate 69. The cap portion 57 is attached to the tip of the marker 51 positioned horizontally.

When the rod 58 of the marking cylinder 59 is extended, the holder 54 is pressed via the joint portion 68, and the rear roller 53 is raised along the curved portion 55a of the guide groove 55 so that the holder 54 is raised. It inclines to the front. As a result, the marker 51 swings downward integrally, and marks the terminal with electric wire 63 on the work receiving base 63. The work receiving base 63 is disposed on the front wall portion 70 of the apparatus main body, and rotates downward around the support shaft 72 against the tension spring 71 for buffering, as in the previous example, to buffer the impact at the time of marking.

When the markers 51 of different colors are used, the pair of long and short linear cylinders 61 and 62 for selecting the markers are used.
Drives the swinging plate 56 via the slider 60. The slider 60 has a vertical plate portion 60a fixed perpendicular to the rear end of the swinging plate 56, and a vertical plate portion 60a.
And a connecting portion 60b fixed to the rear surface of the vehicle.
The vertical plate portion 60a engages with a pair of upper and lower horizontal guide rails 74 of the apparatus main body support portion 73, and the connecting portion 60b.
Is connected to the body 62a of the shorter movable cylinder 62 by passing through the horizontal slot 75 of the support portion 73.
And can be slid in the marker side-by-side direction.

On the lower side of the movable cylinder 62, a long fixed cylinder 61 is fixedly provided on the support 73 of the apparatus main body. The distal ends of the reciprocating rods 76 and 77 between the fixed cylinder 61 and the movable cylinder 62 are connected by a movable connecting plate 78. The stroke ratio between the fixed cylinder 61 and the movable cylinder 62 is set to two to one. Then, as shown in FIG. 7, the movable cylinder 62 is fully extended or compressed in the most compressed state of the fixed cylinder 61, or the movable cylinder 62 is fully extended or compressed in the most extended state of the fixed cylinder 61, so that the movable cylinder 62 can be moved in four ways. The position of the cylinder body 62a is obtained (in FIGS. 6 and 7, the dashed line indicates the movement). By moving the position of the body 62a in the horizontal direction, each holder 54, that is, each marker 51 is moved horizontally, whereby a desired marker 51 is automatically selected.

[0025]

As described above, according to the present invention, the marker
ー Selection drive means selects the marker and puts it on the work cradle
Since it is accurately positioned at the opposing position, a marker of a desired color is automatically selected from a plurality of markers and positioned.
Then, the marking driving means can oscillate the marker to automatically perform marking on the terminal with electric wire, etc., so that the marking is performed accurately and efficiently.
This significantly reduces the number of marking steps.
In addition, since the work receiving table absorbs the impact at the time of marking with the buffer spring , smooth and clear marking is achieved.
