Description

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 various continuous forms into individual forms, that is, a cutting device for processing continuous forms into single forms.

[0002]

2. Description of the Related Art Up to now, a cutting device for cutting a continuous form having continuous feed holes at both edges into individual forms has been widely used, for example, in an enclosing and sealing device and other devices. However, this type of cutting device generally used conventionally has a structure as shown in FIG. That is, in the known cutting device 1, after passing through processes such as printing and writing, it is wound into a roll or alternately 1 as shown in the drawing.
The claws 5 of the transport unit 4 are fitted into the transport holes 3 continuously provided on both side edges (FIG. 4) of the continuous form 2 folded in the opposite direction one by one, and the continuous form 2 is sequentially drawn out. For example, send this to the OMR device 6 that reads a bar code,
Then, the continuous form 2 was sent to the slitter unit 7. In the slitter unit 7, first, a slitter device 8 such as a rotary slitter is provided with a continuous form 2 as shown in FIG.
A vertical cut is made to act in parallel with the traveling direction of the continuous form so as to separate the transporting hole portions 3 on both side edges of the continuous form, and then the continuous form 2 is further fed from the slitter device 8 by a predetermined size and provided there. A cutter device 9 such as a rotary cutter or a blade cutter acts in a direction orthogonal to the traveling direction of the continuous form 2 to perform a horizontal cut for cutting the continuous form 2 into a predetermined length one by one, while a slitter from the continuous form 2 is used. The transport holes 3 on both side edges of the continuous form vertically cut by the device 8 were shredded by the dedicated shredding blades 10 and thus individual forms were cut off from the continuous form.

[0003]

The known cutting device 1 as described above greatly improves the processing of the continuous form 2. But,
Poor conveyance of the continuous form 2 or read error of the OMR device 6 may occur. In such a case, it is necessary to immediately stop the conveyance of the continuous form 2 when it is determined that a defect has occurred and correct the defect or error.

However, in the known cutting device shown in FIGS. 3 and 4, even if the continuous form 2 is to be supplied to the slitter unit 7 again after the defect or error is corrected, in many cases the transport hole 3 is already formed. I couldn't retry because it was cut off. In order to solve such a problem, it is necessary to position the OMR device 6 and the slitter unit 7 sufficiently apart from each other. However, in order to install the OMR device at the upstream position of the transport section, there is a problem with reading accuracy and the like, which requires a separate assist device, which not only increases the cost but also increases the size of the entire device,
It gets complicated.

Further, in the known apparatus, when cutting a continuous form into a single form, in addition to a slitter for vertical cutting and a cutter for horizontal cutting, a dedicated shredding blade 10 for further cutting the transport hole 3 is provided. Was needed. This has led to an increase in the number of parts, and has been one of the factors that prevent the miniaturization of the device.

[0006]

In order to solve these problems, the present invention replaces the position of the vertical cutting device and the position of the horizontal cutting device of the conventional cutting device, and does not require a shredding blade. It is what

[0007]

[Function] In order to cut the continuous form fed through the conveying section into single sheets, first the continuous form is cut horizontally along with the conveying holes, and then the conveying hole is longitudinally cut. Form a single vote. Since the transport hole is slit after the lateral cut, it is easy to retry when the continuous form is re-sent after adjusting the defective feeding of the continuous form. In addition, since the transport hole is cut at the same time during the horizontal cutting, the blade for shredding the transport hole is not necessary.

[0008]

1 and 2 are views similar to FIGS. 3 and 4 showing a continuous form cutting device according to the present invention.

In the cutting device 20 of the present invention, as in the known cutting device 1 shown in FIG. 3 and FIG.
After passing through a predetermined process such as printing or writing, 2 is wound into a roll or alternately folded one by one in the opposite direction as shown. The continuous form 22 has elongated transporting hole pieces 24 continuously formed at one side edge or both side edges (FIG. 4). In the transport hole piece 24, the claw 28 provided on the feed belt constituting the transport section 26 is provided.
Are fitted. When the feed belt of the transport unit 26 is rotated by the drive motor 30, the claw 28 sequentially feeds out the continuous form 22, pulls it out to the OMR device 32 for reading a bar code, and then the continuous form 22.
Is sent to the cutting section 34. The above is the same as that of the known cutting device 1.

In the cutting unit 34, the continuous form 22 sent from the conveying unit 26 is first of all the cutter device 3
6 and then enter slitter device 38, then
Enter the advance roller 40 and the scrap roller 42. The continuous form 22 passes between upper and lower cutter blades of the cutter device 36, and a pair of upper and lower feed rollers 40 on the downstream side.
It is sandwiched between and further flows down slightly from the continuous form 2
When the OMR device 32 senses that the tip of 2 has advanced from the cutter device 36 by a predetermined dimension corresponding to the length of a single-cut sheet, the upper cutter blade of the cutter device 36 moves toward the lower fixed cutter blade. By descending, a horizontal cut is performed to cut the continuous form 22 one by one in a direction perpendicular to the advancing direction of the continuous form 22 into a predetermined length. At this time, the cutter device 36 simultaneously cuts the transporting hole portion 24 at the side edge portion of the continuous form 22.

Next, the form 22 is cut into a predetermined length, and at the same time, a slitting device 38 such as a rotary slitter acts in parallel with the advancing direction of the form 22 as shown in FIG. Transport hole piece 24
Make a vertical cut to separate.

In the present invention, when the cutter 36 cuts the continuous form 22 into a single form, the slitter 38 which is always in the cut state while the leading end of the form 22 is already held by the feed roller 40. Transport hole piece 2 for form 22
Cut off 4. Therefore, in practice, the portion of the form 22 held by the feed roller 40 is in a state where the transport hole piece 24 has already been cut off. Therefore, after the cutter 36 operates on the continuous form 22, the feed roller 40 holds the cut sheet, which is cut to the predetermined size in the front, rear, left and right, and sends the cut sheet to a downstream enclosing and sealing device, for example.

On the other hand, the transport hole piece 24 cut off by the slitter 38 hangs downward from there and is sandwiched by the scrap rollers 42 and guided onto the scrap conveyor or the like. Of course, since this scrap has already been cut into a predetermined length, it can be dropped directly onto the scrap conveyor or the like.

[0014]

According to the present invention, the vertical cutting mechanism 38 for cutting off the carrying hole piece is located downstream of the horizontal cutting mechanism 36. For this reason, when the continuous form is conveyed by a predetermined amount, the OMR
Even if a read error occurs in the mechanism 32, the continuous form can be retried by conveying the continuous form in the opposite direction before performing the horizontal cutting, and the occurrence of defective products can be minimized. ..

Further, in the conventional cutting apparatus, after the vertical cutting, the tape-shaped scrap-carrying hole piece for cutting is cut and a cutter dedicated to the scrap is installed in order to reduce the bulk of the scrap. According to the invention, the lateral cutting mechanism 36
Since the piece is cut, the dedicated cutter is unnecessary, and the device can be downsized because of the egg.
