Description

[Detailed description of the invention] (Field of industrial application) This invention is a method of printing continuous paper having a row of pin holes for feeding along both left and right edges, printed out using a computer, etc., to a predetermined size. The present invention relates to a continuous paper feeding device with a slitter device for cutting off the margin portion of a device for cutting paper into single sheets.

(Prior Art) Conventionally, in this type of continuous paper cutting device, the paper feeding device and the slitter device are set individually according to the paper width of the continuous paper and the position of the paper margin.

In addition, a device in which a paper feeding device and a cutting device are integrated so that their positions can be adjusted in the width direction of the paper is disclosed in Japanese Patent Application Laid-open No.
It is known from Publication No. 53-25107.

(Problem to be solved by the invention) When the above-mentioned settings were performed individually, the operator wasted both time and effort.

Furthermore, although the device disclosed in Japanese Patent Application Laid-Open No. 53-25107 can respond to changes in paper width, the relative relationship between the cutting device and the paper feeding device cannot be adjusted. Therefore, the margin part of the paper cannot be cut properly, and it is not used when cutting the margin part is not necessary.

The present invention was devised to solve these problems, and its purpose is to save the operator's time and effort by easily setting continuous paper on the cutting device. This eliminates wasted paper and allows the margins of the paper to be cut appropriately.

(Means for Solving the Problems) In order to achieve the above object, the present invention has a paper pin feeding device having rows of feeding pin holes along both left and right edges, A frame including a slitter device for dropping the margin portion downward and arranged side by side with the slitter device first in the paper feeding direction is installed to be adjustable and fixed to the cutting device body in the width direction of the paper, and The present invention provides a continuous paper feeding device with a slitter device, which further comprises a slitter device fixed and adjustable in the width direction of the paper to the frame.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. FIG. 1 is a schematic diagram of a continuous paper feeding device A with a slitter device of the present invention incorporated into a cutting device main body B.

At the front and back of the cutting device main body B in the direction in which the continuous paper P flows, there are stacking sections C for folded continuous paper P.
and a receiving part d for cut paper, that is, a cut sheet P', and the cutting device main body B includes a paper feed device a, a slitter device b, an infeed roller e, a blade f, and a buster in the flow direction of the continuous paper P. A roller g is provided.

Continuous paper P is fed by paper feed device a from stacking section c, its margin part P'' is cut off by slitter device b, and after passing through infeed roller e, burster roller g is fed from infeed roller e. Since the rotation speed is slightly increased, tension is applied to the continuous paper P, and at this time the blade f
descends and presses the continuous paper P to cut the transverse perforation, and discharges the continuous paper P as a cut P' to the receiving part d.

In the present invention, out of such a series of devices, the paper feeding device a and the slitter device b are mounted on the same frame that is adjustable in the sheet width direction with respect to the cutting device main body B, as shown in FIG. It is something.

That is, in the continuous sheet feeding device A with a slitter device of the present invention, as shown in FIG.
It is attached to the same key-shaped frame 1
is adjustable in the sheet width direction with respect to the cutting device main body B. A key-shaped frame 1 is shown in FIG.

Since the apparatus A of the present invention has margins on both sides of the continuous paper,
As shown in FIG. 4, it is also provided on the opposite side.

The paper feeding device a includes a feeding portion of a pin belt 3 stretched inside the case 2, and a paper guide plate 4.
and a paper holding plate 5. The pin belt 3 is stretched over a rotating plate (not shown) provided on a spline drive shaft 6 and an adjusting screw 7, and the pins of the pin belt 3 are attached to the case. It protrudes above 2. Case 2 has its upper mounting plate 8
The paper guide plate 4 is fixed to the lower surface of the paper guide plate 4 with screws 9, and the paper guide plate 4 is attached to the upper surface of the frame 1 with screws 10. Further, the paper holding plate 5 is pivotally attached to a protruding piece 11 protruding from the upper mounting plate 8 of the case 2, and a spring 12 is stretched between the paper holding plate 8 and the upper mounting plate 8. There is.

In FIGS. 2 and 3, the paper presser plate 5 is shown in an open state.

Frame 1 to which this paper feeder a is attached
A hexagonal shaft stay 13 and a spline drive shaft 6 extending from the cutting device main body B pass through the cutter body B, and these also pass through the case 2.

The lower end of an eccentric fixing lever 14 rotatably provided on the upper mounting plate 8 comes into contact with the stay 13.

In FIG. 2, the fixed lever 14 is in an upright state, and its lower end is in contact with the surface of the stay 13 of the hexagonal shaft, and the paper feed device a is in a fixed state with respect to the stay 13, and it can be moved to either the left or right side. When the stay 13 is laid down, it can slide together with the frame 1 in the axial direction of the stay 13, allowing adjustment in the paper width direction.

As shown in FIG. 6, the slitter device b has an upper slitter blade 16 and a lower slitter blade 17 installed inside a box-shaped case 15, and the drive shaft 18 of the lower slitter blade 17 is
It extends from the cutting device main body B and penetrates the frame 1 and the wall of the box-shaped case 15. Rotation of the upper slitter blade 16 is effected by a gear 19 located outside the box-shaped case 15 and meshing with a gear (not shown) on a drive shaft 18.

A gear (not shown) can slide on the drive shaft 18 using a keyway or the like.

Above the box-shaped case 15 is a frame 1.
A stay 20 fixed to the box-shaped case 15 extends through the guide bar 21.
pass through the frame 1 and are adapted to keep the slitter device b parallel to the stay 20 when sliding along it.

This slitter device b has a box case 15.
However, in FIG. 3, the fixed lever 22 and the rotating rod 22' provided above are at right angles,
When the fixed lever 22 is in the illustrated position, the rotating rod 22'
is fixed in contact with the stay 20 surface, and by rotating the fixed lever 15 to the right, the rotating rod 2
The contact from the stay 20 side of 2' is removed.

Further, reference numeral 23 in the box case 15 is a guide groove provided in the box-shaped case for guiding the cut-off and natural-falling margin portion P'' downward.

The continuous paper feeding device A with a slitter device of the present invention as described above is configured to move the cutting device main body B by the hexagonal shaft stay 13, the spline drive shaft 6, and the drive shaft 18 extending from the cutting device main body B. When the hexagonal shaft stay 13 is released from contact with the hexagonal shaft stay 13 by lowering the fixed lever 14, the entire device A can slide in the axial direction. When the rotation rod 22' is released from contact with the stay 20 by rotating it, the slitter device b can be slid along the stay 20.

That is, the paper feeding device a and the slitter device b, which are arranged in parallel on the frame 1, can be adjusted simultaneously with respect to the cutting device main body B, and the slitter device b can be adjusted with respect to the frame 1 separately.

First, when using the device A of the present invention, the continuous paper P
When cutting from the inside of the pin hole rows on both sides (the center side of the paper), the upper and lower slitter blades 16 of the slitter device b are cut in advance from the inside (center side of the paper) with respect to the pin rows of the pin belt 3 of the paper feeder a. , 17, and by rotating the fixed lever 22, the stay 20 is set with the rotating rod 22'.

In this state, if the device A is slid on the stay 13 of the hexagonal shaft and set on the stay 13 with the fixed lever 14 according to the width of the continuous paper P, the position of the slitter device B is also changed. inevitably determined.

In addition, if it is not necessary to cut off the margins P'' on both sides of the continuous paper P, cut off the slitter device b in advance.
The upper and lower slitter blades 16 and 17 may be set at positions away from the continuous paper P.

Furthermore, the device A of the present invention is
Even after being set up, the slitter device b can be moved if necessary.

(Effect of the invention) In general, when continuous paper printed out by a computer and having rows of pin holes for feeding along the left and right edges is cut into sheets of predetermined dimensions, the dimensions of the paper are changed. Rather than changing the dimensions of this paper, the pattern printed on the slip is often changed. Moreover, since the width of the margin part is not standardized, the margin part is often cut off along the printed pattern of the cut sheet, even if it has perforations.

The present invention provides a device that is effective in such cases, and the continuous paper feeding device with a slitter device of the present invention is such that the entire set of the paper feeding device and the slitter device, which are installed in parallel on a frame, is connected to the cutting device. Since sliding adjustment is possible with respect to the main body, and only the slitter device is configured so that sliding adjustment is possible with respect to the frame, the operator using this device must adjust the slitter device relative to the paper feed device. By setting the related positions in advance, the position of the slitter device is automatically determined just by setting the paper feed device according to the paper width, and the margin can be set accurately regardless of whether there are perforations or not. It can be cut, and continuous paper can be dealt with quickly, saving time and effort.

In other words, setting the relative position of the slitter device with respect to the paper feed device in advance means that the width of the margin section based on the paper pin hole can be determined and set in advance, and it is difficult to determine the setting position. The slitter device can be easily set up.

Further, when the margin portion does not need to be cut in order to use the pin holes of the continuous paper as binding holes, the slitter device can be set at a position away from the continuous paper.

Furthermore, even after setting the paper feed device, if it is necessary to finely adjust the cutting width of the margin portion along the printed pattern of the cut sheet, it is possible to make adjustments by moving only the slitter device relative to the paper feed device. You can also do it. Therefore, the margin portion can be appropriately cut.

However, the cut margin part naturally falls downward and falls in a place where it is gathered by the guide groove of the box-shaped case, so there is no direct need for a winding device, and therefore a winding device equipped with one is not necessary. The structure is simpler, and even if the slitter device is moved, the cut margins will fall downwards, so it is necessary to roll the paper along with the paper feeding device so that the winding position will not be disturbed like in the case of a device equipped with a winding device. The structure for moving the collecting device can be omitted.
