Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a paper attached to a bundle of newspapers which is counted, accumulated and conveyed on a conveyor after printing in a shipping factory such as a newspaper company. The present invention relates to a paper slip producing apparatus for printing slips.

[Conventional technology]

The paper form is printed using continuous paper. The content printed at this time is important transportation information such as the number of copies of a newspaper bundle, which shop it is sent to, and by what route.

In this type of device, a paper roll is pulled out, the above information is printed on the paper, and then cut by a cutter. However, in a device equipped with one cutter, the cutting size is different without reducing the paper-sheet making speed. It was not possible to continuously produce paper slips.

[Problems to be Solved by the Invention]

By the way, in shipping factories such as newspaper companies, not only "standard paper sheets" with specific dimensions but also different sizes, such as "paper sheets with notice" 1.5 times the above paper sheet size, It uses a paper form called "paper form" to save labor,
Recently, there has been a strong demand for an apparatus capable of producing paper sheets having different sizes at high speed, randomly, and in real time, which is aimed at automation.

Under such an environment, it is not possible to produce paper slips of different sizes at the same speed as the "standard paper slip" production speed by the conventional technology as described above. , I have been preprinted and prepared in advance to deal with the actual work, but with such a method, not only is there a limit to improving the work efficiency, but also on the newspaper bundle conveyed on the conveyor. You can manually attach a paper slip that matches the stack, or you can install a separate paper slip supply device and mechanically attach it.
I was forced to perform a very troublesome work process.

The present invention has been conceived in view of the above, and it is possible to fabricate paper sheets having different sizes randomly and continuously in real time, without slowing down the paper sheet production speed, Therefore, of course, it is not necessary to separately preprint different sizes of paper slips and prepare them for storage, and it is not necessary to separately install a dedicated supply device for paper slips and to control each operating member. It is an object of the present invention to provide a paper sheet making apparatus capable of easily performing the above.

[Means for Solving the Problems]

In order to achieve the above object, the paper form manufacturing apparatus according to the present invention is provided with a plurality of print heads along a running path of continuous paper and a plurality of cutters on the downstream side thereof,
At least two adjacent print heads, including the most downstream side, are operated at the same time to perform printing, and cut at a predetermined print area length to create paper slips of different lengths. A plurality of print heads are provided at equal intervals so that each printing operation position is l ₁ pitch, and each of the plurality of cutters is arranged so that each cutting operation position is at the same pitch as the print head interval l _1. The print operation position of the print head on the most downstream side and the cutting position of the cutter on the most upstream side are provided with a distance of an integer multiple of 2 or more of the print head interval l ₁ , and the fast-forward means for fast-forwarding the continuous sheet is provided, after the continuous paper to complete the printing area by the printing run by intervals l ₁ of the print head, at least, it causes fast forward only the distance l ₁ It has a structure in which a controller for selectively actuating one of a plurality of cutters according to the mutual relationship between the length of the fast-forward length and the preceding operation a paper form to be cut and the position of the cutter.

[Work]

A command from a control unit (not shown) that totally controls this system causes a plurality of print heads to share and print the form information of a predetermined size on the continuous paper that is pulled out from the web and runs. Randomize at least two different sizes of paper without slowing down the paper making speed by selecting one of the cutters and operating it after fast-forwarding for the length related to the paper size. Are continuously manufactured.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 schematically shows the overall configuration of the paper-sheet making apparatus according to the present invention. A continuous paper 1 in the form of a roll is pulled out from a paper feed unit and printed by a printing unit 2, and then a cutting unit 3 is used. It is designed to be cut into a predetermined size.

In this embodiment, referring to FIGS. 1 and 3, two types of address paper slips shown in FIGS. 2A and 2B, that is, the length in the printing direction is the standard dimension L ₁ (= 2l) ₁ ) Standard address paper form A
Then, a flow of producing the notice-addressed form B having a length L ₂ (= 3l ₁ ) which is 1.5 times the standard address-form A will be described.

The printing unit 2 has an interval l _{1 that} is 1/2 the printing length L ₁ of the standard form A.
Therefore, the three print heads 4a, 4b, 4c are arranged at equal intervals in order from the downstream side in the traveling direction. Each of the print heads 4a, to 4c faces the rollers 5a, 5b, and 5c so that they can come into contact with and separate from the rollers, and by pressing the rollers 5a to 5c, the rollers 5a can be pressed. , ~
Predetermined printing is performed on the continuous paper 1 running on the 5c. Further, one roller 5a among the above-mentioned three rollers 5a, 5c is a paper feed roller and is connected to a motor (for example, a pulse motor) 6 so that the motor 6 can perform fast feed. .

The cutting unit 3 is set to the position whose 2l ₁ to the downstream side from the most downstream side of the printhead 4a of the printing unit 2, the two cutters 7a disposed further respectively now to the position of the l ₁ on the downstream side, 7
It consists of b.

Then, the separation / contact operation of each print head 4a, 4c of the printing unit 2, the motor for driving the paper feed roller, and each cutter
The operations of 7a and 7b are controlled by commands from a control unit (not shown).

In the above structure, the continuous paper 1 pulled out from the paper roll is printed by the print heads 4a to 4c of the printing unit 2, and then cut into a predetermined size by the cutting unit 3. The print heads 4a, 4c of the printing unit 2 and the cutters 7a, 7b of the cutting unit 3 are operated by commands from a control unit (not shown).

Now, the print head 4 is the starting point of the first shared printing area for paper forms A and B.
When the first print point P ₁ where a is located and the second and third shared print area start points are the second and third print points P ₂ and P ₃ where print heads 4b and 4c are located, standard As an example of the order in which the form A and the form B with notice are printed at random, it is assumed that they are input in advance in the order of A-B-B-A-A ... The actual operation will be described with reference to (A) to (N) shown in FIG. (B) of FIG.
In (N), the dotted line indicates the length of the standard form A, the dashed-dotted line indicates the length of the notice form B, and the double line with the solid line along these lines completes printing in the printing unit 2. Each of the parts is shown.

FIG. 3B shows a state in which the print heads 4a and 4b are in contact with the continuous paper 1 in order to print the standard paper form A.

Of FIG. 3 (C) travels a distance l ₁ at the continuous paper 1 is printed feedrate, during which the print head 4a on the continuous paper 1, by sharing at _{4b L 1/2 (= l} 1) by A standard paper form A having a length L ₁ is printed, and the print heads 4 a and 4 b are separated from the continuous paper 1.

FIG. 3D shows the state of FIG. 3C, in which the pulse motor 6 fast-forwards by l ₁ to send out the printed portion from the printing unit 2, and the cutter 7a operates to feed the continuous paper 1. Is in a state in which the tip portion of is cut.

Further, FIG. 3D shows a state in which the print heads 4a to 4c are in contact with the continuous paper 1 in order to print the next notice paper sheet B.

Figure 3 of the (E) is the third view of the state of (D) traveled by l _1, the respective print heads 4a, L _2/3 by sharing to inform with paper length L ₂ at ~4c The state in which the slip B is printed and the print heads 4a to 4c are separated from each other is shown.

From the state of FIG. 3 (F) is in the FIG. 3 (E), after the fast-forward the continuous sheet 1 in _{2L 2/3 (= l 2} ) by the motor 6, the cutter 7b is operated, wherein Standard paper form A printed earlier
The rear end is cut off. Note that l ₂ = 2l ₁ .

After that, in (G) to (N) of FIG. 3, printing, fast-forwarding, and cutting operations are performed for each paper sheet A-B-B-A- by repeating the above operation.
A ... Each paper slip is produced in order without fail and reliably repeated.

As described above, the three print heads 4a, 4a, 4a of the printing unit 2 are
when c is printed working after the completion of printing, each print head 4a immediately, at the same time allowed to separated from the continuous sheet 1 in unison ～4C, the continuous paper 1 in the spaced 2L _2/3 (=
l ₂ ) Fast-forward by the amount and when two print heads of the printing unit 2 work to print, immediately after the completion of printing, both print heads 4a and 4b are simultaneously separated from the continuous paper 1 and at the same time. , controls the motor 6 receives a command of the continuous paper 1 in this spaced from _{L 1/2 (= l 1} ) the amount by not shown to fast-forward control.

And, as the cutters 7a and 7b of the cutting unit 3 always work, as is easily understood from the changing states of (B) to (N) in FIG. When the rapid feed amount is l ₁ , the cutter 7a
When it is l ₂ (= 2 × l ₁ ), the cutter 7b operates.

From the above, whether the cutter 7a operates or the cutter 7b operates even if subsequent paper sheets with different cutting dimensions are randomly input is determined by the rapid feed amount after printing is completed, and this is surely printed. It is cut into paper sheets with dimensions that match the area.

〔The invention's effect〕
