Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a batch marker that attaches a mark for separating a continuous form every predetermined number of pages to the continuous form.

[0002]

[Prior art]

 In the production of continuous forms used in office processing by computers, etc., first, printing is performed on continuous paper according to the purpose of use, and then marginal punch holes are provided on both sides. Next, perforations are made at predetermined intervals, and folding is performed at the perforations. This continuous form in the folded state must be separated for each ordered page. For this reason, at the final stage of manufacturing continuous forms, a device called a batch marker is used to put marks on the continuous forms to separate them for each ordered page.

In the batch marker, marking is performed by bringing an ink roller into contact with a continuous form that continuously runs. That is, perforations can be recognized by setting the marking interval (how many pages are marked) and the number of pages (mark length) marked in one marking. The number of pages of the continuous form that is run by is counted by the ink roller for the continuous form of the set number of pages (for example, for every 10 sheets for every 510 sheets). Is attached. Incidentally, an electromagnet has been used in the past to bring the ink roller into contact with the continuous form.

[0004]

[Problems to be solved by the device]

 In order to be able to recognize the above-mentioned mark from the side surface of the folded continuous form, as shown in Fig. 2 (a), it is necessary to mark near the perforation 12a on the mountain side. However, the above-mentioned conventional batch marker only counts the number of pages by perforations, and recognizes whether each perforation is on the mountain side 12a or the valley side 12b when the continuous form is folded. I can't. For this reason, three or more sheets (usually about 5 to 10 sheets) are marked so that the mountain side 12a is surely marked. Pages marked with a mark in the continuous form cannot be used as products and are discarded.

In addition, since the ink roller is moved by the electromagnet during marking and its speed is constant, the starting position of the marking (the position where the ink roller starts contacting the continuous form) and the length of the mark are continuous form. It changes according to the traveling speed of. On the other hand, the operator can re-set the mark length (the number of pages to be marked) according to the traveling speed, but such a setting change is not only complicated, but continuous forms can be printed. Since the counting is done in units of pages, there is a limit to accuracy in the timing of marking start and adjustment of the mark length. Therefore, in order to make sure that the mountain side is marked and that the continuous form to be shipped does not become smaller than the number of ordered pages (to prevent loss), allow a sufficient margin for the marking interval and mark length. Was there. As a result, more pages will be discarded because they are marked in the continuous form, and the product will include extra pages that exceed the number of ordered pages. As a result, more raw paper is needed to produce a product with a certain number of pages.

The present invention has been made in order to solve such a problem, and an object of the present invention is to set a predetermined number of pages and a required minimum number of pages regardless of the running speed of a continuous form. The aim is to provide batch markers that can be reliably marked only on numbers.

[0007]

[Means for Solving the Problems]

 According to the present invention made to solve the above-mentioned problems, when a continuous form having a marginal punch hole and perforations for dividing a page is in a running state, the ink roller is brought into contact with the continuous form so that the continuous form is continuous. In a batch marker that marks every predetermined number of pages of a form, a) speed detection means for detecting the running speed of the continuous form, and b) distance detection for detecting the running distance of the continuous form by counting marginal punch holes. Means, c) driving means for bringing the ink roller into contact with the continuous form at a speed corresponding to the running speed, so that the mark attached to the continuous form has a predetermined length within two pages, and d) the running Drive control means for activating the drive means when the distance reaches a predetermined value.

[0008]

[Action]

 Before running the continuous form, the perforation on the mountain side is placed near the contact position of the ink roller, and the position (this is called the reference position) is stored in the drive control means. When the continuous form starts traveling, the speed detecting means detects the speed and the distance detecting means detects the traveling distance. The driving means brings the ink roller into contact with the continuous form so that the length of the mark attached to the continuous form becomes a predetermined value (however, within two pages of the continuous form) according to the traveling speed of the continuous form. The speed is decided beforehand. The term "speed" as used herein refers to the speed of the entire operation from the time when the driving means brings the ink roller into contact with the continuous form until it is released. , To release continuously, change the moving speed, move the ink roller at high speed to bring it into contact with the continuous form, hold it in that state for a specified time, and then release at high speed. , Change the time that the ink roller is in contact with the continuous form.

In the drive control means, the mark (applied to the continuous form by the operation of the drive means) crosses the perforations on the mountain side after the predetermined number of pages have passed, and does not exceed the pages on both sides of the perforation. The running distance of the continuous form from the reference position is calculated in advance, and the drive means is started when the running distance of the continuous form reaches the predetermined value. As a result, the incrawler reliably marks the mountain-side misses that divide the specified number of pages regardless of the running speed of the continuous form.

Embodiment A batch marker which is an embodiment of the present invention will be described below with reference to FIGS. 1 and 2. This batch marker is placed in the latter stage of the manufacturing device (not shown) for the continuous form 10 and receives the continuous form 10 sent from the continuous form manufacturing device at a speed of about 50 to 150 m / sec to perform the marking process described later. It is something to give. The continuous form 10 sent from the continuous form manufacturing apparatus is provided with marginal punch holes 16 and perforations 12.

As shown in FIG. 1, the batch marker of the present embodiment includes a roller 34 with a sprocket that engages with the marginal punch hole 16 of the continuous form 10 and a rotary connected to the rotary shaft of the sprocket roller 34. An encoder 36, a roller 32, an ink roller 20 for attaching the mark 14 to the continuous form 10, a stepping motor 24 for reciprocating the ink roller 20, and a controller 30 are provided. The rotary encoder 36 generates a pulse corresponding to the marginal punch hole 16 of the continuous form 10 and sends it to the control unit 30. The ink roller 20 reciprocates by the cam 22 and the crank mechanism 26, and the stepping motor 24 rotates the cam 22 in response to a signal from the control unit 30. Normally, the cam 22 is at the position shown in FIG. 1, and the ink roller 20 is separated from the continuous form 10. When the cam 22 makes a half rotation, the ink roller 20 comes into contact with the continuous form 10 and marks 14 are formed on the continuous form 10. When the cam 22 rotates a further half turn, the ink roller 20 separates from the continuous form 10 and the marking ends.

The continuous form 10 that has passed the roller 32 is folded at the perforations 12 by the folder 40.

The method of using the batch marker of this embodiment is as follows. Before running the continuous form 10 continuously, the value of the interval L between the perforations 12 of the continuous form 10 (see FIG. 2B) sent, the number of pages Pn of the continuous form 10 to be secured during marking , The length Lm of the mark 14 is input to the control unit 30, the perforation 12a on the mountain side is placed on the roller 32 by the folder 40, and a predetermined button is pressed to make the control unit 30 the standard of the continuous form 10. Teach the point. The length Lm of the mark to be input is set to 2 × L or less (for example, Lm = L) so that the marking does not extend over three pages or more.

When the continuous form 10 is continuously run, the control unit 30 detects the running speed Vf and the running distance Lf of the continuous form 10 by the pulse signal from the rotary encoder 36. The control unit 30 calculates the rotational speed Vr of the stepping motor 24 from the detected running speed Vf of the continuous form 10 as follows. First, the length Lm of the mark 14 is divided by the traveling speed Vf to obtain the time tm at which the ink roller 20 should be in contact with the continuous form 10. From the positional relationship between the cam 22 and the crank mechanism 26, the rotation angle range Ar of the cam 22 on which the mark 14 is attached to the continuous form 10 is known. Therefore, the rotation speed Vr of the cam 22 (that is, the stepping motor 24) is calculated so that the cam 22 rotates in this rotation angle range Ar at the time tm.

The control unit 30 also calculates a running distance (predetermined distance) Lp from the reference point of the continuous form 10 for determining the timing of activating the stepping motor 24 as follows. First, it is determined whether the predetermined page number Pn is an odd number or an even number. If it is an even number, 2 is added to Pn, and if it is an odd number, a value obtained by adding 3 to Pn is set as the marking interval page number Pm. A value (Pm × L-Lm-α) obtained by multiplying the number of pages Pm by the length L of one page of the continuous form 10 and then subtracting the marking length Lm + α is set as the predetermined distance Lp. This α is a distance that takes into consideration the time from the start of the stepping motor 24 to the start of marking, and the time from the end of marking to the end of one rotation of the stepping motor 24 and the stop.

The control unit 30 compares the running distance Lf from the reference point (or after the end of the previous marking) of the continuous form 10 detected by the pulse from the rotary encoder 36 with the above predetermined distance Lp, When Lf = Lp, the stepping motor 24 is rotated once at the above speed Vr. As a result, after the predetermined number of pages Pn of the continuous form 10 is secured, the mountain side perforation 12a sandwiching the next two pages (or the next two pages with one page left) is reliably marked. After the cam 22 completes one revolution, the value of the traveling distance Lf is initialized to zero.

When the predetermined number of pages Pn is an odd number, marking is not performed within 2 pages but is performed over 3 pages (in this case, the marking length Lm is not less than L, for example, 2 × L). However, you may specify the pages to be discarded.

Although the traveling speed of the continuous form 10 is detected by the pulse of the rotary encoder 36 in the above embodiment, it may be detected separately. For example, a speed signal provided from the continuous form manufacturing device preceding the batch marker may be used. Further, although the cam 22 is continuously rotated by 360 ° in the above-described embodiment, it is initially rotated by 180 ° at a high speed and then stopped to bring the ink roller 20 into contact with the continuous form 10 for a predetermined time tm. After the lapse of time, the ink roller 20 may be further rotated by 180 ° to be separated from the continuous form 10. In this case, the control unit 30 calculates the time tm during which the ink roller 20 is kept in contact with the continuous form 10 as Lm / Vf based on the length Lm of the mark 14 and the traveling speed Vf of the continuous form 10. Then, the running distance Lf of the continuous form 10 becomes (Pm × L−Lm−α) (α in this case is the running distance of the continuous form 10 corresponding to the time required for the cam 22 to rotate 180 ° back and forth). At this time, the stepping motor 24 is started.

[Effect of device]

 As described above, according to the present invention, a mark including a perforation can be provided in two adjacent pages on the mountain side perforation every predetermined number of pages, and thus the number of pages to be marked. Is the minimum necessary. Moreover, regardless of the running speed of the continuous form, since it is possible to reliably attach such marks on two pages for each specified number of pages, it is necessary to provide a margin for the marking interval and mark length, unlike the conventional method. There is no. As a result, there will always be only two pages discarded due to the mark, and there will be no extra pages in the product beyond the number ordered. Therefore, products with the same number of pages can be manufactured with less raw paper than in the past. Another advantage is that we can offer products exactly as many as the number of order pages. The batch marker of the present invention is particularly effective in the case of stacking a plurality of continuous forms into one product, because the effect of saving the number of discarded papers is great.
