Description

Description: TECHNICAL FIELD The present invention relates to a cutting device that cuts a continuous form after printing to form a unit form, a decorator that disassembles a continuous form set into parts, or a postcard. The present invention relates to a processing device that constitutes a part of a continuous paper processing machine such as a sealer for making envelopes and booklets, a bookbinding machine, and the like, and more particularly to a processing device for processing a continuous marginal portion that has been cut and separated.

2. Description of the Related Art Conventionally, in a series of processes performed by a continuous paper processing machine, the above-described division into continuous paper such as a fed continuous form,
Prior to performing processing such as disassembling, it is usual to cut and remove marginal portions at the left and right ends of the continuous paper, which usually have a width of 1.27 cm or more. Then, the marginal part that has been cut and removed becomes a continuous strip of paper with a width of 1.27 cm to 2.54 cm, which falls by its own weight into the storage box placed below the continuous paper processing machine and is removed at an appropriate time. Abandoned

However, with the recent increase in speed of continuous paper processing machines, the number of times of discarding work has increased, and there has been a demand for reducing the number of times of this complicated work.

In order to meet this demand, conventionally, as a means for reducing the bulk of marginal waste in a storage box, firstly,
A method in which marginal waste in the storage box is sucked by a blower and then conveyed to a waste paper collection place through a duct. Secondly, a winding mechanism is provided in the storage box to wind up the marginal waste (US Pat. No. 3,857557). And Japanese Utility Model Laid-Open No. 60-50643), and thirdly, a method in which marginal scraps are cut into pieces each having a length of about 10 cm (see JP-A-57-126344).
Is proposed.

Problems to be Solved by the Invention However, according to the first method, the processing apparatus becomes large and accompanied by noise, so that it is not suitable for offices, etc. which are general use facilities for continuous paper processing machines. There is an inconvenience. According to the second method,
There is an inconvenience that the device is larger than the third system in terms of mechanical structure including the drive mechanism of the device.
Furthermore, according to the third method, small pieces of marginal waste stick to the inside of the machine due to the influence of static electricity or spill from the storage box, which complicates cleaning work and cuts the marginal part from continuous paper. Immediately after doing the cutting work for fragmentation, it is necessary to cut while changing the traveling direction of the cut marginal part downward,
There is an inconvenience that a jam easily occurs at the transfer tractor portion of the continuous paper and the cutting and separating portion of the marginal portion.

The present invention eliminates these inconveniences, while the advantage of being superior to the storage efficiency of the cutting method is left, the cleaning work is easy, the jam is hardly generated, and the marginal portion cut and separated from the continuous paper is processed. It is an object of the present invention to provide a processing device for doing so.

A means for solving the problems: a transfer unit composed of a tractor and rollers for transferring continuous paper such as continuous forms, and a marginal cutting unit composed of a slitter and a cutter blade for continuously cutting the marginal part of the continuous paper, A rotary conveying unit, which is provided below the marginal cutting unit, and which conveys the cut continuous marginal unit downward at a speed lower than the conveying speed of the transfer unit, and a rotary conveying unit including a pair of rollers or the like. It comprises a slitter provided on the rotary shaft of the transport section, a cutter blade, or a cutting section made of a spiral blade provided on the peripheral surface of the rotating body.

By setting the conveying speed of the cut marginal portion to be lower than the transfer speed of the continuous paper, the cut marginal portion cuts at a cutting portion such as a cutter blade in a loose and meandering state, so that the cutting is performed. The marginal part is cut into smaller pieces than before, for example, 20 to 30 cm pieces. In this way, by cutting the marginal portion into small pieces that are, for example, 2 to 3 times as long as the conventional one, it is less likely to be affected by static electricity, less likely to spill from the storage box, and the traveling direction changes completely downward. Jam is less likely to occur because it is cut from the

Practical Examples Hereinafter, preferred embodiments in which the present invention is applied to the processing of continuous forms will be described in detail with reference to the accompanying drawings.

Here, FIG. 1 is a schematic side view with a part of the continuous paper processing device taken as a cross section, and FIG. 2 is a schematic front view of the same with a part taken as a cross section.

As shown in FIGS. 1 and 2, the marginal portions 3a and 3b provided at the left and right ends of the continuous form 1 are cut forward of the tractor 2, which is a transfer unit for transferring the continuous form 1, in the transfer direction. The slitters 4a and 4b, which are marginal cutting portions, are provided. A pair of low speed rollers 14a, 14b and a pair of high speed rollers 15 are provided further forward of the slitters 4a, 4b in the transfer direction.
The continuous form 1 in which the transfer rollers composed of a and 15 are provided and the marginal portions 3a and 3b are cut and separated by the slitters 4a and 4b is the pair of low speed rollers 14a and 14b and the pair of high speed rollers. In the process of being transferred by 15a, 15, the cutter blade 16 divides into a single sheet. Although not shown, the continuous paper processing machine is further configured to transfer the single-cut forms and stack them on the stacker unit.

Below the slitters 4a and 4b, the marginal parts 3a and 3b are cut and separated from the continuous form 1 and descend in a continuous state so as to be positioned slightly ahead of the continuous form 1 in the transfer direction.
The folding guide 5 in the shape of a rectangular tube, in which the gap in the transfer direction is set to about 5 cm by the pair of side plates 5a, 5b, for folding in a meandering manner, is inclined so that the lower part thereof is located in the front in the transfer direction. It is arranged. This folding guide 5
A pair of rotating shafts 6 and 7 are located close to each other under the continuous form 1
It is rotatably provided so as to extend in a direction perpendicular to the transfer direction of. These rotary shafts 6 and 7 are metal rollers 8a, 8b and 9 each having a knurling process on a pair of circumferential surfaces that are rotationally transporting portions and are spaced apart in the axial direction (however, one of the pair is not shown). ) Is provided. The pair of metal rollers 8a, 8b and 9 are rotated so as to convey the separated continuous marginal portions 3a and 3b at a speed lower than the transfer speed of the tractor 2. A pair of cutter blades 10 (only one of which is shown) serving as a cutting portion are provided on the rotary shafts 6 and 7 of the pair of metal rollers 8a, 8b and 9 located at these intervals. In addition, each metal roller 8a, 8
Below the b and 9, the marginal parts 3a, 3b are the cutter blades 10
A storage box 17 for storing the marginal waste 13 cut into small pieces by is installed.

The rotational drive force of the tractor 2 and the rotary shafts 6 and 7 is transmitted from a rotary drive source (not shown) of a continuous sheet processing machine through an appropriate rotation transmission mechanism.

 Next, the processing operation of this embodiment will be described.

Continuous form 1 transferred horizontally by tractor 2
The marginal parts 3a, 3b are cut and separated when passing through the slitters 4a, 4b, and the separated marginal parts 3a, 3b are guided into the rectangular tubular folding guide 5 and sequentially descended. Then, the metal rollers 8a, 8b and 9 are pulled in in a state where the direction is changed in the vertical direction. Here, since the transport speed of each of the metal rollers 8a, 8b and 9 is set to be lower than the transport speed of the tractor 2, the cut and separated marginal portions 3a and 3b are shown in FIG. As you can see, it becomes loose, meandering and folded. In this state, the cut and separated marginal portions 3a, 3b are further drawn into the respective metal rollers 8a, 8b and 9 and transported downward, and at the same time, the portion corresponding to the cutter blade 10 is cut and the length is reduced.
Marginal scraps 13 of 20 to 30 cm are dropped into the storage box 17 one after another.

In addition, the length of the marginal waste 13 in the present embodiment is 20 ~
Although it was explained as 30 cm, this length is the side plates 5a, 5 of the guide 5.
It can be adjusted by the distance between b and the speed of reduction of each brush roller 8a, 8b and 9 with respect to the transfer speed of the tractor 2. Further, the transfer unit may employ a pair of rollers in place of the tractor 2, and the marginal cutting unit may be a slitter 4
Not only a and 4b, but also continuous paper with perforations for cutting in the marginal parts 3a and 3b, the transfer force in the direction of separating from the continuous paper is applied to the marginal parts 3a and 3b, and A means for continuously separating along the perforations or a cutter blade that moves up and down may be adopted.
Further, as the rotary conveying unit, instead of the metal rollers 8a, 8b and 9, a pair of rollers such as a rubber roller, a sponge roller and a brush roller may be appropriately used, or a rotating body having an uneven peripheral surface may be used. Furthermore, instead of the cutter blade 10, the cutting portion may be a slitter or a cutting member having an appropriate shape formed on the peripheral surface of the rotating body. further,
The shape of the folding guide 5 is not limited to the rectangular tube shape, and the side plates 5a and 5b are set so as to gradually face each other so as to gradually face each other, and the marginal portions 3a and 3b are guided to the central portion. Alternatively, an oscillating plate that oscillates so as to distribute the marginal portions 3a and 3b in the axial direction of the rotary transport unit may be provided, and the oscillating plate may also serve as the side plates 5a and 5b.

Effect As is clear from the above description, according to the present invention, the transfer direction of the marginal portion cut from the continuous paper such as the continuous form is changed from the horizontal direction to the vertical direction, and then the marginal portion is slackened. Since it is cut into marginal scraps, the bulk of the marginal scraps in the storage box can be prevented, the continuous operation time of the continuous paper processing device can be extended, and the length of the marginal scraps can be increased within the non-bulky range. In addition, it is possible to obtain an effect that it is hard to be affected by static electricity, is hard to spill from the storage box, and prevents a jam, and enables a smooth processing operation.
