The laser marker shown at 400 in FIG. 2 is a place for laser marking a serial number (N) and a bar code (BC) designated through a computer in advance on a designated portion of the strip 10 supplied along the guide rail 310. As the laser marker 400 itself uses a known one, a detailed structure thereof is omitted, except that the serial number (N) and the bar code (BC) marked by the laser marker 400 are stored in a computer, which will be described later. The computer system 600 is combined together for this purpose because it must be programmed to match and use the inspection data of the inspection apparatus 500.

Meanwhile, the laser marked strip 10 is transferred to the position where the inspection apparatus 500 is installed by the pusher 350L, and the inspection apparatus 500 photographs the package 30 formed on the strip 10 and is input in advance. Compared with the reference image of the defective product detects whether the defect is stored in the computer system 600 as data.

Therefore, the data obtained from the laser marker 400 and the inspection apparatus 500 is stored in the computer system 600 to perform the process work necessary only for the good package by using the data in the next process of processing the strip 10, Since the product does not need to perform the next process work, it gives a sorting function to exclude the process application.

Inspected strip 10 is sequentially stacked in the empty magazine of the strip mounting portion 700 by being pushed to the rear end of the transfer channel portion 300 by the pusher 800, the magazine on which the strip 10 is mounted is a conveyor Iterative process is withdrawn and the new magazine is supplied, but these methods are well known and thus the description is omitted.

Next, the process of marking the strip using the present invention will be described.

As shown in FIG. 5, when the magazine 20 loaded with the strip 10 is placed in the magazine supply unit 100 and transferred to the home position, the locking bar 22 of the magazine 20 is opened by the proximity sensor 900. If it is closed (if it is in the locked state), a warning device (for example, a buzzer or flashing of a tower lamp, etc.) connected to the proximity sensor 900 notifies the operator to release the locking state.

The strips 10 stacked in the magazine 20 are pushed up by the pusher 200 in order from the top to the first zone of the conveying channel part 300, and by the draw picker 50 the first zone 300A. Is drawn). The magazine 20 rises one space by a separate means, causing the pusher 200 to sequentially push the strip 10.

When the transfer position is detected by a sensor (not shown), the strip 10 is moved to the position of the laser marker 400 by the pusher 350, and a predetermined serial number (set by the operator at a portion of the strip 10) The bar code BC, into which N) and necessary information are input, is printed with a laser and the data is stored in the computer system 600.

Strip (10), the marking operation is completed is pushed to the inspection device 500 by a separate pusher (350L).

Pushers (350, 350L) installed in the conveying channel unit 300 for the pushing operation is left in the lower position than the pushing position except for pushing the strip 10, it is raised again for the pushing operation It is designed to not interfere with the transport of the strip 10 is given to the appearance.

The strip 10, which has been transferred to the inspection apparatus 500, is used to determine whether there is an external defect for each package 30 (for example, missing or incorrect printing of package classification, as well as screening damaged packages, etc.). After comparing the predetermined base image and the photographed package (30) to distinguish between good and bad goods and stores this data in the computer system 600.

Therefore, it is possible to determine which package of a particular strip is defective based on the data in a later step, and control the computer system 600 so as not to perform a subsequent step operation on the defective package. In addition, it is possible to reduce economic and time waste by not performing post-processing on the defective package.

In particular, the strips 10 supplied to the first zone 300A to the third zone 300C on the transfer channel part 300 may be simultaneously transferred, thereby preventing work delay due to the transfer.
