Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting device for cutting a wide paper into a predetermined size, and more particularly to a continuous wide paper after recording in an electrostatic recording device and the like in both the vertical and horizontal directions. The present invention relates to a cutting device for cutting into a cut sheet of a predetermined size.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 4 and 5, a device of this type has a conveying roller 2 for feeding a paper 1 to be cut.
And the pressing roller 3 and Y for cutting the paper 1 in the width direction.
A cutting device 4, an X-cutting device 5 for cutting the paper 1 in the conveying direction, a discharge roller 6 and a pressing roller 7 for discharging the cut paper, and a discharging roller 6 and a pressing roller for the paper that has left the X-cutting device 5. It is provided with upper and lower guide plates 8a, 8b, etc. for guiding between 7. The Y-cut device 4 includes a fixed blade 9 and a rotary blade 10 that runs along the fixed blade 9. Further, the X-cut device 5 includes a lower blade roller 12 attached to the rotary shaft 11 and an upper blade 13 provided so as to partially contact the lower blade roller 12. Furthermore, the rotating shaft 11
Includes a feed roller 14 having an outer diameter substantially equal to that of the lower blade roller 12.
Is attached, and a pressing roller 15 is also provided above it.

In the cutting device having this structure, the long and wide paper 1 to be cut is taken up by the conveying roller 2 and the pressing roller 3, and is conveyed further downstream by the feeding roller 14 and the pressing roller 15 of the X-cut device 5, At that time, the lower blade roller 1
2 and the upper blade 13 to cut in the conveying direction, and by cutting at a suitable timing in the width direction by the Y-cut device 4, a plurality of cut sheets 1a of a predetermined size,
After that, it was guided by the guide plates 8a and 8b, and discharged by the discharge roller 6 and the pressing roller 7. Here, if inch-type roll paper is used as the paper 1 and is cut into an ISO (JIS) size cut sheet, unnecessary portions (edge paper) 1b are generated at both ends, and the edge paper 1b is also required. Like the cut sheet 1a, it is guided by the guide plates 8a and 8b and discharged by the discharge roller 6 and the press roller 7.

[0004]

However, in such a structure, the necessary cut sheet 1a and the unnecessary selvage paper 1b are simultaneously ejected to the same position by the ejection roller 6, which is confusing. There was a problem that 1b got in the way. Further, since the edge paper 1b is usually thin, there is a problem that a jam easily occurs between the X-cut device 5 and the discharge roller 6. Further, when the edge paper 1b is thin, there is a problem that the conveying force (tension) at the discharge roller 6 may affect the X-cut and bend and cut.

In order to separate the cut sheet 1a and the edge paper 1b, a guide 17 is provided downstream of the discharge roller 6 to separate the cut sheet 1a and the edge paper 1b as shown in FIG. There are things, but in this configuration guide 1
7 is necessary, and when the selvage 1b gets on the cut sheet 1a between the X-cutting device 5 and the discharge roller 6, the guide 17 cannot separate it, which is a satisfactory solution. I couldn't say that.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a cutting device capable of separating the edge paper from the cut sheet with a simple structure.

[0007]

In order to solve the above-mentioned problems, the present invention provides a discharge roller provided downstream of the X-cutting device only at a position for guiding a necessary cut sheet.
At the traveling position of the edge paper downstream of the cutting device, a guide is provided to guide the edge paper coming out of the X-cut device below the traveling path of the cut sheet from the X-cut device to the discharge roller. Is.

[0008]

According to the present invention, with the above-described structure, after the paper is cut by the X-cutting device into the required cut sheet and the unnecessary ear paper, the running path between the cut sheet and the ear paper is immediately separated, and the cut sheet is Although it is sent to the discharge roller and discharged through the discharge roller, the edge paper is sent below the cut sheet by the guide and discharged. For this reason, the edge paper is not mixed in the cut sheet and is not sent to the discharge roller, so that a jam is not generated and the cut sheet does not get on the cut sheet. Furthermore, since the ear paper is not subjected to tension after cutting, it does not affect the X cut.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic side view showing a cutting device according to an embodiment of the present invention provided for cutting electrostatic recording paper in an electrostatic recording device, and FIG. FIG. 3 is a schematic perspective view of a part thereof, and the same parts as those of the conventional example shown in FIGS. 4 and 5 are designated by the same reference numerals. 1 to 3, 1 is a paper to be cut (electrostatic recording paper), 2 is a conveying roller, 3 is a pressing roller, 4 is a Y-cutting device,
It consists of a fixed blade 9 and a rotary blade 10. 5A is an X-cutting device that cuts the paper 1 in the transport direction, and has a lower blade roller 12 attached to the rotating shaft 11 and an upper blade 13 provided so as to partially contact the lower blade roller 12. Furthermore,
A feed roller 14A having an outer diameter substantially equal to that of the lower blade roller 12 is attached to the rotary shaft 11, and a pressing roller 15 is also provided above the feed roller 14A. A circumferential groove (not shown) is formed on the feed roller 14A so that the round belt 20 can be hung on the groove. A drive unit (not shown) is connected to the rotary shaft 11.

A discharge roller 6A is arranged downstream of the X-cut device 5A and is rotatably held by the support shaft 21. The support shaft 21 is held by a rotatable arm 22 on the rotary shaft 11, and the arm 22 is fixed so as not to move by an appropriate support tool (not shown). A circumferential groove (not shown) is also formed on the discharge roller 6A,
The round belt 20 is hung using the groove. The round belt 20 has a function of transmitting the rotation of the feed roller 14A to the discharge roller 6A and a function of guiding the cut sheet 1a. A flat belt may be used instead of the round belt 20, and in that case, the feed roller 14
Grooves may not be provided in A and the discharge roller 6A. The discharge roller 6A and the round belt 20 are provided only at the traveling position of the cut sheet 1a and are not arranged at the conveying position of the edge paper 1b. A pressing roller 7 is provided above each discharge roller 6A.

At the running position of the edge paper downstream of the X-cutting device 5A, the edge paper 1b exiting the X-cutting device 5A is guided below the path of the cut sheet 1a extending from the X-cutting device 5A to the discharge roller 6A. A guide 23 is provided. Normally, the discharge roller 6A is arranged at the same level as the feed roller 14A of the X-cut device 5A,
The cut sheet 1a that exits is fed horizontally, and the edge paper 1b is fed obliquely downward by the guide 23.

The operation of the cutting device configured as described above will be described below. The long and wide paper 1 to be cut is taken up by the conveying roller 2 and the pressing roller 3, and is conveyed further downstream by the feed roller 14A and the pressing roller 15 of the X-cutting device 5A, at that time, the lower blade roller 12 and It is cut in the carrying direction by the upper blade 13. Further, the Y-cutting device 4 is activated at an appropriate timing, whereby the paper 1 is laterally cut. This allows the paper 1
Is cut into a cut sheet 1a of a predetermined size and the tabs 1b at both ends. Cut sheet 1 exiting X-cut device 5A
The a is guided by the round belt 20 and the upper guide plate 8a, is fed between the discharge roller 6A and the pressing roller 7, is discharged to the outside of the apparatus by the discharge roller 6A, and the tray, the receiving box provided at that position, It is stored in a stacker or the like (not shown). On the other hand, the edge paper 1b is guided by the downwardly inclined guide 23 as soon as it leaves the X-cut device 5A, and is discharged to the outside of the device through a traveling route different from that of the cut sheet 1a.
It is placed in an ear paper receiver (not shown). Thus, since the cut sheet 1a and the edge paper 1b are discharged separately from each other, the discharged cut sheet 1a can be accumulated separately from the edge paper, and the accumulated cut sheets 1a can be easily taken out. Also, it becomes easy to design a stacker or the like for receiving the cut sheet. Further, unlike the conventional example shown in FIG. 6, it is not necessary to provide the guide 17 downstream of the discharge roller 6. Further, since the edge paper 1b does not pass between the narrow guide plates 8a and 8b as in the conventional case, and is simply guided and discharged on the inclined guide 23, no jam occurs and tension is maintained. Since it is not affected, it does not affect the X-cut.

In the above embodiment, the discharge roller 6A is driven by the round belt 20 hung between the discharge roller 6A and the feed roller 14A, and the cut sheet 1a is guided by the round belt 20. Not limited to this,
The discharge roller 6A may be fixed to the support shaft 21 and the support shaft 21 thereof may be driven by an appropriate means, or as a guide means for guiding the cut sheet 1a from the X-cut device 5 to the discharge roller 6A. Instead of the round belt 20, a guide plate fixedly provided at a fixed position may be used as in the conventional case.

[0014]

As is apparent from the above description, according to the present invention, the discharge roller provided on the downstream side of the X-cut device is provided only at the position for guiding the necessary cut sheet, and the edge paper running on the downstream side of the X-cut device is run. At the position, a guide is provided to guide the edge paper coming out of the X-cut device below the traveling path of the cut sheet from the X-cut device to the discharge roller. Immediately separates the edge paper and sends it to the downstream side, the cut sheet is ejected by the ejection roller, and the edge paper can be ejected by a guide along a traveling route different from that of the cut sheet. Since it is possible to separate and stack the cut sheets, it is easy to take out the cut sheets that have been stacked, and the edge paper is sent to the discharge roller through between narrow guide plates. It therefore is not without jamming, yet there is no effect on the X-cut undergoes no tension has the effect of such may be carried out a good X-cut.
