Description

Description: TECHNICAL FIELD The present invention relates to a continuous paper cutting device used in computers and the like having perforations along the edges.

TECHNICAL BACKGROUND Continuous paper with perforations along both edges is used as paper for printing computer output.

In such paper, after printing, the perforated portion (edge portion where the perforation is provided) is separated along pre-provided perforations.

In addition, such paper is provided with perforations for cutting in the transverse direction at regular intervals along its length, and the continuous paper is cut along the perforations to form paper of a predetermined length. It is now possible to do so.

However, after such paper is printed, the operator manually cuts the perforations and the crosswise mint lines in the perforations, for example, when the paper is used as a payment slip. There is a problem in that when a large number of slips are created, the task of separating them becomes extremely complicated.

Therefore, it is desirable to be able to perform such a separation operation automatically, but a device for this purpose has not yet been developed.

OBJECTS OF THE INVENTION In view of the above, an object of the present invention is to provide an apparatus that can automatically or semi-automatically cut continuous paper as described above.

In other words, the first device according to the present invention cuts the portion of continuous paper provided with perforations and longitudinal perforations for separation along the edge into the perforations. A feeding device for feeding one of the perforated portion and the paper main body portion inside the perforated portion (perforated portion P in the embodiment described below) along a certain plane. means (in the same example,
(Composed of chain conveyor 22 and holding cover 24)
and a means for separating the two parts by pulling the other part of the one part being fed by the feeding means in a direction forming an angle with the plane (in the same embodiment, the holding cover 24 edge 24' and tension roller pair 2
6);

In the above device, one of the perforation portion and the main body portion of the paper is fed along a certain plane, and
Since the other part is pulled at a certain angle, a shearing force is applied to the perforation, thereby shearing the perforation and separating the two parts from each other.

Further, a second device according to the present invention is provided in a continuous sheet of paper having perforations and vertical perforations for separation along the edge thereof, which are provided in the transverse direction at predetermined intervals in the length direction of the sheet. A device for separating the paper at a cutting perforation in which the paper is separated, comprising a tenth roller means (implemented as a pair of drive rollers 16 in the same embodiment) for feeding the paper at a predetermined speed; a first pair of roller portions (in this implementation, they are implemented as large diameter portions of conical rollers 46 and 48) that rotate to sandwich one edge of the sheet fed by the means and send the same edge; and a second pair of roller parts (the small diameter of the rollers 46 and 48 (embodied as parts), and the first pair of roller parts is made to have a faster circumferential speed than the second pair of roller parts, giving a difference in the feed speed of said two parts, thereby and second roller means (implemented as a pair of conical rollers 20 in the same embodiment) for performing the above-described separation.

In this device, one edge of the paper is pulled relative to the rest of the paper, thus exerting a shearing force on the transverse perforation provided in the paper, which causes The paper will be separated at the perforation. It is preferable that this cutting is carried out over the entire perforation, but even if it is carried out only partially, it will be much easier to carry out the subsequent manual cutting operation.

EXAMPLES Hereinafter, the present invention will be explained in detail based on examples shown in the accompanying drawings.

FIG. 1 shows a cutting device 1 according to the present invention, which separates continuous paper Y after it has been printed and output from a computer.

As shown in the figure, this device includes an idler roller 10° 12, a device 14 set between both idler rollers for separating the perforated portion P of the paper from the paper main body H at the longitudinal perforation M1, and the paper main body A pair of driving rollers 16 for driving and conveying the paper by sandwiching the paper, and a pair of conical rollers 20 for cutting the sheet passed through the rollers along the transverse perforation M2 in cooperation with the pair of rollers. ing.

Device 14 for separating the perforation part P;
consists of a pair of chain conveyors 22 installed along both sides of the paper to engage with the bottom surface of the perforation and convey it, a restraining cover 24 to prevent the paper from floating up, and a chain conveyor 22 located at the center of the paper. It is provided with a pair of tension rollers 26 that apply tension to separate the main body portion H from the perforation portion P.

The chain conveyor 22 is provided along the lower side of the perforated portion of the paper to support the lower side, and protrusions 28 that are inserted into each perforation of the perforated portion are provided at regular intervals on the outer periphery of the chain conveyor 22. ing.

As can be seen from FIG. 3, the holding cover 24 has both side edge portions facing the chain conveyor 22 and sandwiching the perforation portion P between them, and also receives the protrusion of the chain conveyor. A groove 30 is provided. Further, the center portion between the above-mentioned both side edge portions of the holding cover is recessed so that a recess 32 is formed on the downstream side with respect to the sheet conveyance direction when viewed from above. Also, on the upstream side, it is set so as to come into contact with the upper surface of the paper being conveyed.

The tension roller pair 26 is composed of a pair of rollers 40 and 42 arranged above and below the paper, and these rollers have a length that approximately corresponds to the width of the main body portion H of the paper. It is set within the recess 32. As can be seen from FIG. 2, these rollers 40.4.
The nip (that is, the portion that pinches the paper) formed by the presser cover 2 is located above the downstream lower edge 24' of the central portion of the presser cover. One of these rollers is connected to a motor (not shown) and acts to pull the sandwiched paper body upward.

Next, a device for cutting the paper along the transverse perforation M2 will be described.

That is, this device is composed of a drive roller pair 16 and a conical roller pair 20. The driving roller pair 16 is composed of a pair of rollers 43 and 44 set to sandwich the paper, one of which is connected to a motor (not shown) so as to send out the sandwiched paper at a constant speed. .

The conical roller pair 20 is composed of a pair of conical rollers 46 and 48 arranged above and below the paper, and as shown, these conical rollers are of the same size and have the same diameter. The parts are arranged in correspondence with each other. One of these conical rollers is connected to a motor (not shown) and is driven to rotate to drive and eject the sandwiched paper, and the conveying speed of the paper portion that engages with the smaller diameter portion is The portion of the paper that engages the slower, larger diameter portion will have a faster transport speed. Preferably, the slow portion of the paper is at approximately the same speed as the speed delivered by the pair of drive rollers. Therefore, the paper between the drive roller pair 16 and the conical roller pair 20 will be under greater tension closer to the edge that is engaged with the larger diameter portion of the conical roller, and therefore the paper will be under greater tension. will be separated along the transverse perforation M2. Furthermore, the setting between the roller pair 16 and 20 is as follows:
A belt conveyor 50 conveys the paper body being sheared between both pairs of rollers. Further, reference numeral 52 indicates a guide member for guiding the paper main body that is separated and discharged.

To operate the above device, first, the operator manually separates the perforation portion P from the paper main body portion H over a certain length from the leading edge of the paper, and then puts the paper in the state shown in Figure 1 and then uses the device. Pass it through. In this case, it is preferable to bend the perforation portion P of the paper portion to be applied to the idler roller 10 as shown in the figure.

By doing so, when the device is activated and the paper is advanced, the perforated portion P of the paper passed over the idler roller 10 is folded following the folded perforated portion, and then the paper is folded back to its original position. It will be returned to the state of 1 and move forward. This makes the perforation easier to shear, and is particularly preferred when the paper is formed by stacking a plurality of sheets, such as paper for slips.
