DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bar code marker, and in particular, draws a thin plate-like work stored in a cassette from the cassette, reads characters printed on the work, and displays a bar code label corresponding to the characters. The present invention relates to a barcode marker that is attached to a work and then stored in the same cassette again.

[0002]

2. Description of the Related Art In a conventional bar code marker, for example,
A conveying _mechanism as disclosed in Japanese Utility Model Application _No. 01-087039 _.
Is used.

[0003] A conventional barcode marker will be described in detail with reference to the drawings. FIG. 9 is a front view showing an example of the related art. FIG. 10 is a side view of FIG. The barcode marker shown in FIG. 9 and FIG. 10 has a pair of guides 401 which have a horizontal conveying surface and are installed horizontally and parallel at a certain interval, and a flat plate-shaped member which is located between the pair of guides 401 and which can be opened and closed. A chuck 402 having a claw 403 and movable in a direction parallel to the guide 401; a uniaxial stage 404 for driving the chuck 402; A movable cassette elevator 405, a CCD camera 407 installed above the pair of guides 401, and a CCD
An illumination optical system 408 fixed to the tip of the camera 407;
And a bar code label printing / applying device 409 installed above the end of the guide 401 opposite to the cassette elevator 405.

Next, the operation of the conventional bar code marker will be described. The uniaxial stage 404 is driven into the cassette 350 set on the cassette installation surface 406 of the cassette elevator 405 to insert the claw 403 of the chuck 402 to grip the thin plate-shaped work 360. Work 3 after gripping
60, the one-axis stage 404 is driven to
1 and slide it out of the cassette 350 by a certain amount. Next, the character 361 printed on the work is read by the CCD camera 407, and the barcode label 362 corresponding to the read character is printed and attached to the work 360 by the barcode label printing and pasting device 409. After the attachment, the one-axis stage 404 is placed in the cassette 3
The work 360 is driven in the direction of 50 to house the work 360 in the cassette. After the storage, the grip of the chuck 402 is released, and the one-axis stage 404 is driven to move the claw 403 out of the cassette 350. Next, the cassette elevator 405 is driven to send the next work to a position at the height of the guide 401, and the same operation is performed up to the last work in the cassette.

FIG. 11 is a front view showing _another conventional example. The conventional barcode marker shown in FIG.
02, and a pair of take-out guides 601 that are horizontally and parallelly installed at regular intervals, and a take-out guide 601.
And a pair of storage guides 603 disposed horizontally and parallel to the take-out guide 601 at the same interval above the take-out guide 601, and having a horizontal transport surface and having a minute space at one end of the take-out guide 601. A vertically movable stage 605 having a guide 604 located at a connected position and horizontally and parallel to the take-out guide 601 and a pair of take-out guides 601
A chuck 606 having a flat claw 607 that can be opened and closed and movable in a direction parallel to the guide, a uniaxial stage 608 for driving the chuck 606, and a tip portion between the pair of storage guides 603. A pusher 609 which is movable in the guide direction, a rodless cylinder 610 for driving the pusher 609, and a pair of extraction guides 601
A cassette elevator 611 having a flat cassette installation surface 612 and being able to be driven up and down is located at an end face opposite to the stage 605, a CCD camera 613 installed above the stage 605, and fixed to the tip of the CCD camera 613. An illumination optical system 614 and a bar code label printing / pasting device 615 installed above the stage 605 are included.

[0006] Next, the operation of the bar code marker of _this will be explained. The uniaxial stage 608 is driven into the cassette 550 set on the cassette installation surface 612 of the cassette elevator 611 to insert the claw 607 of the chuck 606 to hold the thin plate-shaped first work 551. After the holding, the first work 551 is driven on the one-axis stage 608, slides on the transfer surface 602 of the pair of take-out guides 601, and is transferred from the inside of the cassette 550 to the drawer guide 604. After the transfer, the chuck 606 releases the grip and retreats backward.
Next, the first work 551 is lifted to the height of the storage guide 603 by the stage 605. After completion of the lifting, the characters printed on the work are read by the CCD camera 613, and the barcode label corresponding to the read characters and the sticking to the first work 551 are performed by the barcode label printing / pasting device 615.

[0007] chuck 606, lifting ends and moved to simultaneously one-axis stage 608 by the _Rica set 550 direction of the first workpiece 551, second in the cassette 550 after sending the cassettes 550 one pitch by the cassette elevator 611 The work 552 is gripped, the uniaxial stage 608 is driven, and the work 552 is pulled out onto the pair of extraction guides 601. Second
After confirming that the work 552 has been pulled out, the first work 551 of the cassette 550 is operated by the cassette elevator 611.
Is moved to the height of the storage guide 603. The first work 551 is stored in the cassette 550 by moving the pusher 609 in the direction of the work cassette 550 by the rodless cylinder 610 after the barcode label has been attached. After storage, the stage 605 is lowered to the height of the take-out guide 601 and the chuck 606 is
Conveys the second work 552 onto the guide 604.

[SUMMARY OF THE INVENTION Conventional bar code markers described above, the withdrawal of the workpiece from the cassette, because _that going by drawing by grasping the one axis stage the workpiece tip by a chuck at the time of loading and unloading of the workpiece disadvantage behavior or to open gripping the work or is required every time there _Ru. In addition, _Ru drawback there that the bar code pasting of the finished work of the label is tact time many take for accommodating the cassette every time.

[0009] Another conventional barcode marker described above is:
When transporting a thin plate-like work from the take-out guide to the storage guide, the stage is used to move the guide up and down. Therefore, the work transfer space is at least the space where the work is drawn from the cassette and the space where the work is moved up and down by the stage. There is a drawback that a space for each unit is required, and the device becomes large.
