Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a DP bag conveying device used in an automatic print photo bagging system.

[0002]

2. Description of the Related Art When a DP reception shop accepts the simultaneous printing of a photographed photo film, it fills in a predetermined item on a DP bag, puts a patrone in the DP bag, and hands it to a large-scale development laboratory. At this large-scale photo lab, the film cartridge is taken out from the DP bag, and then the photographed film is taken out from the film cartridge. These photographic films are spliced together to form a long film. This long film is developed by a film processor, and then a film inspection by a skilled operator is performed. In this film test, a notch is formed on a frame to be printed, and an exposure correction amount for obtaining an appropriate printed photograph is determined.

Next, the long film is set in an automatic photo printer. The notched frame is printed and exposed on a paper (photographic printing paper) in consideration of the exposure correction amount designated at the film certification. The exposed paper is developed by a paper processor, and then the print inspection is performed with the paper being long. In this print test, re-printing prints that give good results by performing re-printing with different exposures have re-burning marks consisting of, for example, one diagonal line, and uncorrectable unnecessary images such as shooting failures. On the print photograph, an unnecessary mark composed of, for example, two diagonal lines is written on the image with a felt pen or the like.

The roll paper, which has been subjected to the print verification, is loaded into a cutter / sorter, and is cut into each frame here, and is also grouped into one for each case. In this cutter / sorter, a reprint mark or unnecessary mark is detected by a sensor, and based on this mark, one print photograph is sorted into a pass print photograph, a reprint print photograph, and an unnecessary print photograph. The unnecessary print photographs are put in a waste box, and the pass print photographs and the reprint print photographs are discharged to two trays that are inclined. In addition, depending on the width of the paper set in the photo printer, 82.5 × 1 is included in one print photograph.
In addition to the E size of 17 mm and the L size of 89 × 127 mm, there is a panoramic size that is twice as long as these sizes.

On the other hand, the long film which has undergone the printing process is cut into a predetermined number of frames in one photographic film,
The obtained film piece is inserted into the film storage sheet. The operator manually takes out the pass print photograph and the reprint print photograph discharged to each tray and superimposes them. Next, the printed prints that have been put together are collated with the photo film in the film storage sheet, and these are put in a print bag. At this time, advertisement leaflets that print various print services are also put in the print bag together. After inserting this print bag into the original DP bag, only the print photos that have passed are sent to the shipping process. And
The one containing the reprint print photograph is sent to the reprint print step.

[0006]

In the printing system currently in operation, the sorting of print photographs is automated, but the work thereafter is performed manually. Therefore, it requires a considerable amount of manpower to insert a print photograph, a leaflet or the like into a print bag, or to insert the print bag into a DP bag.

Further, an automatic bagging system for printed photographs is disclosed in Japanese Patent Publication Nos. 56-768, 56-35862, 4-70832, and 4-76542.
It is described in Japanese Patent Publication No. These publications describe a device for automatically inserting a leaflet, a print photograph, a film storage sheet, or the like into a print bag, a DP bag, or the like. However, these devices do not describe a specific configuration for laterally conveying the DP bag in an upright state. Moreover, since the thickness of the DP bag changes depending on the contents of the print bag inserted in the DP bag, the DP bag in which the print bag is inserted is vertically conveyed by the conveyance roller pair or the belt pair. In that case, there is a problem in that the DP bag cannot be conveyed properly due to the variation in the thickness of the DP bag. Further, when a thick DP bag is forcibly transported, the negative film or print photograph in the print bag may be damaged and pinched.

The present invention has been made to solve the above-mentioned problems, and even if the thickness of the DP bag fluctuates, the DP bag can be transported in a reliable manner without damaging the contents. The purpose is to provide a device.

FIG. 2 is a schematic view showing an automatic bagging system for printed photographs using the collecting apparatus of the present invention. The paper cutter 10 pulls out the certified paper 11a from the roll paper 11 and conveys it toward the cutting position. During this conveyance, the cut mark sensor detects a cut mark formed of a small hole formed in the side edge portion of the paper 11a. The cutter is operated based on the detection signal of the cut mark to cut the paper 11a and separate it as one print photograph 12. Further, the paper cutter 10 is provided with a sort mark sensor, detects the sort mark indicating the division of each case, and temporarily suspends the cutting operation based on this to sort each print photograph 12 for each case.

The finished state of each print photograph of the paper 11a is verified in advance in the print verification process. In this print test, the pass print photograph with a good finish remains as it is, but if the exposure amount is corrected and the finish is good, for example, the re-baking mark 13 consisting of one diagonal line is an image of the print photograph. It is written on the surface. Further, if the exposure amount is not corrected, the finish is not good, for example, in a defocused print photograph, an unnecessary mark 14 composed of two diagonal lines is written.

The print photo sorting device 17 detects the re-baking mark 13 or the unnecessary mark 14, and based on this, operates each branch guide arranged in the middle of the transport path to change the transport destination of the print photo 12. Thus, the reprint print photograph 12a, the pass print photograph 12b, and the unnecessary print photograph 12c are sorted. The reprinted and passed print photographs 15a and 15b are separately collected.
