Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention receives, from an automatic printing machine, a card-type single piece of paper such as a quality display tag, a price tag, a packing tag, or a seat tag which is printed and discharged by an automatic printing machine.
The present invention relates to an auto stacker for a single piece of paper for vertically stacking and storing.

[0002]

2. Description of the Related Art A conventional auto stacker is shown in FIG.
Also, as shown in FIG. 5, for feeding the single piece of paper 16 printed by the automatic printer 15 or the single piece of paper 16 which is printed on a continuous sheet and cut into a predetermined length with a cutter, which is composed of a belt conveyor. After being placed on the conveyor 8 and pressed by the pressing roller 9 from above to be forcibly discharged, it is configured to be sequentially inserted from below and stacked vertically on the inclined chute 40 (hereinafter, Also referred to as a single piece of paper, including the case of continuous sheets).

On the other hand, there are the following two methods of conveying the single-sheet piece 16 printed by the automatic printer 15 in the width direction depending on the difference in the printing method. One of them is a method of printing while conveying so that the center line of the single piece of paper 16 coincides with the center line of the print head. When the width of the single piece of paper 16 changes, it can be moved to the left and right relative to each other. The pair of guide plates 41 is relatively moved left and right, and the single sheet piece 16 is conveyed along both sides of the guide plate 41. The other is (not shown) even if the width of the single sheet piece 16 is different. In this method, only one side of the single-sheet paper piece 16 is always conveyed along a fixed guide plate attached to one side.

Therefore, when the single sheet 16 having a different width is used, the receiving auto stacker having the structure of the two transfer methods is prepared and attached in order to correspond to the above two transfer methods. I was

[0005]

That is, in the conventional auto stacker, the means for forcibly feeding the single sheet pieces received as described above and the means for aligning and loading the fed single sheet pieces are separated. Is configured. Therefore,
The single piece of paper is opened until the single piece of paper is completely fed onto the chute, and thereafter, it is discharged onto the chute with the momentum utilizing the inertia of the conveying speed of the feeding conveyor. For this reason, as the pieces of single paper become heavier as they are piled up, the weight increases the frictional resistance with the chute, which causes the frictional resistance to slip and cause slippage, which makes it impossible to completely feed the paper to the home position. It caused a situation of stopping. When the single-sheet paper pieces are fed one after another in such a state, there is a problem that they are caught with each other, jammed, or are inserted at an angle.

Further, since two types of auto stackers having the same conveying method as the automatic printer having a structure for conveying a single piece of paper have to be prepared, the equipment cost is high.

The present invention has been made in order to solve the above-mentioned conventional problems, and slips, is obliquely fed, is jammed, or is jammed with each other during the feeding of printed single-sheet pieces. Stack them on the stocker by aligning the front, back, left and right without getting caught.
Another object of the present invention is to provide an automatic stocker for a single-sheet piece that can be used with the same structure even for automatic printers having different conveyance methods.

[0008]

In order to achieve the above object, the present invention endlessly hangs a plurality of round belts between a driving roller and a driven roller. Then, an intermediate roller is arranged between the rollers, the round belt located on the upper side is pushed up from the bottom, bent in a dogleg shape, and a pressing roller is attached on the driven roller to form a feeding conveyor. .

Therefore, the feeding area is defined between the driven roller and the intermediate roller, and the stacking alignment area is defined between the intermediate roller and the main driving roller. It is configured so that the single-sheet pieces can be forcibly conveyed until they are aligned, without opening the single-sheet pieces on the way.

On the other hand, a fixed guide plate is provided on one side of the feeding conveyor, and a lifting portion for the single sheet piece that can be moved up and down is provided above the feeding conveyor, and the head of the fed single sheet piece is applied. A stop guide plate for stopping the positioning is attached movably back and forth.

Further, all of these constituent elements are arranged on a pedestal, the pedestal is mounted on a slide base so as to be movable in the direction perpendicular to the feed direction, and the pedestal is fixed at a predetermined position. Install the screws.

When the continuous sheet is printed and then discharged to the auto stocker without being cut to a predetermined length by the cutter, the printing position is displaced if the continuous sheet is pressed by the pressing roller. It is necessary to release the pressing of the roller. For this purpose, a tension release spring or a compression spring is applied to the shaft of the pressing roller to press the driven roller, and the pressing roller is pulled up against the spring pressure of the spring so that the pressing of the driven roller can be released. It is good to attach. This pressing release member can also be used to adjust the pressing pressure of the pressing roller to an appropriate pressing pressure corresponding to the thickness of the single sheet.

[0013]

The operation will be described. When a single sheet piece is discharged from the automatic printing machine, it is inserted between the pressing roller and the driven roller of the feeding conveyor. The head of the single sheet is sandwiched between a driven roller and a pressing roller arranged thereon, and is placed on a round belt in the feeding area of the feeding conveyor to be fed. The single-sheet pieces that have already been sent to the stacking alignment area are stacked by hitting the stop guide plate on the feeding conveyor. At this time, the bottom piece of the single-sheet paper is placed on the stacking alignment area of the feeding conveyor inclined to the dogleg, and the rear part thereof is lifted up, and its lower surface and the conveying surface of the round belt in the feeding area are arranged. It stands by with a V-shaped open mouth.

Next, when the single piece of paper is fed in by the feeding conveyor, its head is inserted below the lowermost piece of single paper and is fed until it hits the stop guide plate.

When a single sheet of paper having a different width is used, the gantry is moved so that its fixed guide plate is aligned with one side of the single sheet of paper discharged from the automatic printer. Also, if the length of the single piece of paper changes, the stop guide plate is moved back and forth to align with the alignment position. In this way, the individually fed single-sheet sheets are aligned and loaded on the loading alignment area of the feed-in conveyor.
