Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a sheet-fed imprinting device for imprinting a plurality of stacked imprinted objects. Here, the imprinted material means a label, a card, a postcard, a certificate, various tickets, tickets or bags made of paper, plastic, plastic film or the like.

[0002]

2. Description of the Related Art A conventional general sheet-fed type imprinting device comprises a feeding device for feeding a plurality of stacked imprinted products one by one, and a printing device for imprinting each of the delivered imprinted products. ing. As the supply device, there are a friction type in which a delivery belt and a reverse rotation roller are combined and a suction type in which suction is performed by negative pressure. The friction type has an advantage that the structure is simple and the cost is low. Further, as a printing device in the stamping device, a rotary type is generally used.

[0003]

However, although the conventional single-wafer type imprinting device has the advantage that the imprinting is easier and cheaper than the roll type imprinting device, the imprinted products are not supplied one by one. There was a drawback that they were supplied in multiple overlapping states. This has been a major factor in that the imprinted object is not imprinted, the imprint position is displaced, and imperfect imprinting occurs. In particular, in the case of pharmaceutical labels, etc., the label and its contents must match exactly, and it is necessary to check the number of labels and thoroughly manage them so that they will not be lost or confused. Therefore, the conventional single-wafer stamping device has a drawback that although it is simple and easy to stamp, it takes a lot of labor and time to judge the quality of the stamped stamped item.

[0004]

Therefore, the present inventor has achieved the present invention as a result of earnest research in view of the above problems, and is characterized in that a plurality of imprinted articles are stacked. In a stamping device comprising a feeding device for feeding sheets one by one and a printing device for stamping on each of the stamped items fed out, a plurality of multiple stamped items among the stamped items fed from the feeding device are overlapped. Between the feeding device and the printing device, and a multi-imprint detection device for detecting a multi-imprint detection device, and a multi-imprint discharge device that operates in response to signals from the multi-imprint detection sensor to discharge the multi-imprint to the outside of the system. A printing detection sensor for detecting a defective printing imprint among the imprints imprinted by the printing device, and a print operating by the signal of the printing detection sensor to eject the defective imprint imprint out of the system Bad seal The discharge device, to the rear of the indicia shaped device,
There is each one.

As used herein, the term "supply device" refers to a device for feeding a plurality of stacked sheet-fed seals one by one. This device is composed of a loading unit for loading a plurality of stacked sheet-shaped imprints, and a feeding unit for feeding the imprints one by one from the loading unit. The structure of the feeding portion includes the friction type and the suction type as described above, but the friction type may be simple and inexpensive. In the case of the friction type, an adjusting device for adjusting the gap of the reverse rotation roller is provided depending on the thickness and material of the imprint.

The "printing device" refers to a device for printing on imprints supplied one by one from a supply device. The printing mechanism is not particularly limited, and may have a structure in which printing is performed by rotating a hub, a holder or the like loaded with general metal or rubber type characters.

The "multi-imprinted object detection sensor" is a sensor for detecting the overlap of a plurality of imprinted articles fed from the supply device. The method of identifying the multiple stamped items is based on the thickness, the amount of light transmission, and the like. Since the detection accuracy depends on the thickness of the imprint in the case of thickness and the color, thickness, and degree of printing of the imprint in the case of the amount of transmission,
An appropriate type may be adopted depending on the type of the imprint. In addition, a method of detecting the length may be used.

The "multi-imprinted object ejecting device" means that when a multi-imprinted object detection sensor detects that a multi-imprinted object in which a plurality of imprinted objects overlap is sent out, the multi-imprinted object is sent to the printing device. It is a device for eliminating. This device operates in response to signals from multiple stamped article detection sensors.For example, by operating a guide or slide plate for ejection, the stamped article is removed from the normal route, that is, outside the system. It is to be discharged. Therefore, for this purpose, in addition to actuating a guide or the like, any means such as blowing with air may be used.

The "print detection sensor" is for detecting a printing defect of the imprinted matter which is fed one by one from the supply device and printed by the printing device, and is provided behind the printing device. As the detecting means, for example, the printing length or the number of digits of printing is checked, and it is performed by a photoelectric sensor or a laser. The improperly printed imprint detected by the print detection sensor is ejected outside the system by the improper imprint ejector. This improperly printed imprint ejecting device operates in response to a signal from the printing detection sensor and has the same function as the multiple imprint ejecting device described above.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings.

FIG. 1 shows an embodiment of a stamping device 1 according to the present invention, which is for printing on a sheet-fed label L. The imprinting device 1 is for checking whether or not a plurality of sheet feeding labels L loaded in a stacked state and fed one by one, and two or more sheet feeding labels L fed out from the feeding device 2 are overlapped. Of the multi-imprinted object detection sensor 3, and when the multi-imprinted object detection sensor 3 detects the multi-labeled material LL which is a multi-imprinted material in which two or more sheet labels L are overlapped, the multi-labeled material LL is installed outside the system. And a printing device 4 for printing on the non-overlapping sheet labels L fed out from the feeding device 2, and a printing device 4 for printing on the non-overlapping sheet label L fed from the feeding device 2. A print detection sensor 5 for checking print, and a print defect label NL which is a print defect imprint in which a print defect is detected by the print detection sensor 5.
It is composed of a defective print imprint receiving device 51 which is a defective print imprint ejecting device for ejecting the improperly printed product, and a conveyor 6 for sending out the imprinted label GL on which good printing has been performed.

In the operation state of the stamping device 1 shown in this example, first, a plurality of stacked sheet labels L are loaded in the loading section 21 of the feeding device 2. The sheet label L located at the lowermost end is delivered by the delivery belt 22 and the reverse rotation roller 2
In step 3, the single-wafer labels L that overlap the single-wafer labels L are eliminated, so that the single-wafer labels L are sent out one by one. Reverse roller 2
Reference numeral 3 is provided so that it can be adjusted according to the thickness of the imprint by an adjusting knob 24 for changing the gap with the feeding belt 22. The sheet-fed label L is further taken out by the take-out roller 2.
5 is sent to the multiple stamped object detection sensor 3.
The multiple stamped object detection sensor 3 checks the overlap of the sheet labels L. Next, the single-wafer label L is transferred onto the transfer belt 33.
The label leading edge detection sensor 34 provided on the way further detects the label. The label leading edge detection sensor 34 determines the printing position of the sheet label L, and the timing of activation of the printing device 4 is determined by this detection.

The sheet label L is sent from the transfer belt 33 to the printing device 4. When the multiple label imprint detection sensor 3 detects multiple overlapping label LL, it is provided at the exit of the transport belt 33. The external discharge guide 32 is operated to discharge the sheet to the tray 31 before the sheet is sent to the printer 4. In this case, in this example, the outside-system ejection guide 32 is detected by the label tip detection sensor 34.
Is working. In other words, when the multiple-marked object detection sensor 3 detects the multiple-label LL, the label tip detection sensor 34 is switched so as to activate the outside system ejection guide 32 without activating the printing device 4.

The non-overlapping sheet labels L are sent from the transfer belt 34 to the printer 4 for printing. The printing device 4 includes a type roller 41 provided with a type to be printed,
It is composed of a character pressing roller 42, an ink roller 43, and an ink transfer roller 44. Printed sheet-fed label L
While being conveyed by the imprint label transfer belt 52, the print detection sensor 5 checks whether the printing is good or bad. The print detection sensor 5 shown in this example is for checking the number of print digits, and has a structure in which the number of digits read is checked against the number of digits read in advance by the reflected light of the laser. The improperly printed label NL determined to be improperly printed by the imprint sensor 5 is the imprinted label GL on which good printing has been performed.
So that it is not sent to the conveyor 6 for sending out
The imperfect print imprint receiving tray 51 is lowered by the signal from the printing detecting sensor 5 and is stocked on the imprint imprint imprint receiving receptacle 51.

Here, the multi-label LL which is the main part of the present invention
The detection mechanism is a multi-label L with two sheets stacked from the supply device 2.
When L is fed out, the multiple label LL passes through the detection roller 35 of the multiple imprint detection sensor 3 as shown in FIGS. , The actuator 37 is actuated and the detection signal is transmitted. By this signal, the operation of the supply device 2 is stopped, and the multiple label LL is directly conveyed by the transfer belt 33. Then, as described above, when the multiple label LL being conveyed is detected by the label leading edge detection sensor 34,
In response to this signal, the external discharge guide 32 is operated by the guide operating solenoid 39 as shown in FIG. 3, and is discharged to the tray 31. As in this example, the label front end detection sensor 34
The external discharge guide 32 is operated by means of the single label L and the multiple label L that do not overlap on the transfer belt 33.
Since both L exist, it is necessary to discharge the multi-label LL after sending the sheet label L to the printer 4. Therefore, when the length of the sheet label L is long, or when the feeding pitch from the feeding device 2 is large and the interval between the sheet labels L is large,
Directly ejected from the system 3 by the signal from the multiple stamped object detection sensor 3
2 may be activated.
