DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a folding web manufacturing machine for manufacturing a folding web folded in a zigzag manner such as a tissue paper, a towel paper, and the like, and more particularly to such a production. The present invention relates to a sorting mark attaching device for attaching a sorting mark that serves as a mark when sorting a predetermined number of folding webs to be sequentially manufactured by a machine.

(Prior Art) For example, as a manufacturing machine for manufacturing a folded web that is folded in a zigzag shape, such as a boxed tissue paper, a machine shown in FIG. 8 has been conventionally known.
The conventional folding web making machine shown in FIG. 8 cuts the continuous webs Q ₁ and Q ₂ continuously fed from two base paper rolls P ₁ and P ₂ through a pinch roll unit 9A and 9B, respectively. 2B portion, after cutting each continuous web Q ₁ , Q ₂ into short webs (product web length) by cutting devices 2A, 2B, respectively, the short webs on each side of the pair of folding rolls 31A, By the folding device 3 having 31B, the folding webs S are sequentially folded in zigzag.
Can be taken out on the table 11 in a continuous state from the outlet of the folding device 3 through the guide device 10. Further, _one roll of the pinch roll unit 9A is provided in the vicinity of the pinch roll unit 9A installation portion around which the web (continuous web) Q ₁ that constitutes the upper surface side of the folding web S taken out on the table 11 is wound. 9A ₂ is provided with a sorting mark attaching device 104 for instantaneously contacting the surface of the continuous web Q ₁ wound around the outer peripheral surface of the continuous web Q ₁ and coloring the continuous web Q ₁ during traveling for coloring the sorting mark. is set up.

The sorting marker attaching device 104 used in the conventional folding web making machine shown in FIG.
05, is the continuous web Q ₁ on one surface of the continuous web Q ₁ 1
The continuous web Q ₁ is brought into contact momentarily once each time it travels a unit length, and the continuous web Q ₁ has a predetermined short length range (for example, 5 to 10).
(about mm) is configured to be colored. Then, the colored marker portion colored and displayed by the sorting marker attaching device 104 is, after the continuous webs Q ₁ and Q ₂ on each side are sequentially cut into short webs, folded into a zigzag shape and taken out on the table 11. As shown in FIG. 9, the colored mark (reference numeral T) of the web can be visually discerned from the other parts, and the worker can manually distinguish the colored mark parts T, T ... As a guide, the folded web bundle can be separated by a predetermined amount U. In addition, the width of the folding web S manufactured by this type of folding web manufacturing machine is several times as long as the product dimension (6 times in this example), and the product amount U is divided into 1 unit. After taking the product, cut it into the final product dimensions in a separate process (6
Then, a folded web Sa having a final product size as shown in FIG. 9 is manufactured, and the folded web Sa is boxed to manufacture a boxed tissue paper.

(Problems to be solved by the invention) However, in the sorting mark made by using the marking marker attaching device 104 with an ink marker as shown in FIG. 8, the final product (reference numeral Sa in FIG. 10) is used. Although there is only one piece of the short web of 1 unit, which is said to be partly colored (reference numeral T), when the colored short web is used (particularly in FIG. When the short web Ra is spread as shown in FIG. 2), there is a problem that the colored portion T may cause discomfort or discomfort to the eyes. In addition, in the conventional marking device 104 for sorting, the ink marker 105 When the colorant (ink) inside becomes thin, the colorant must be replenished, which is troublesome.

In view of the above problems, the present invention proposes a sorting mark attaching device in a folding web making machine, which is capable of applying a non-coloring sorting mark to folding webs that are continuously taken out on a table. The purpose is to do.

(Means for Solving the Problems) The present invention is to cut each continuous web continuously fed from two base paper rolls by a cutting device to a predetermined size, and fold the cut short webs on each side. In the folding web making machine, the sorting web can be taken out from the exit of the folding section in a continuous state after being folded in a zigzag shape one after another by a continuous web from the installation position of the cutting device. A marker-attaching member that is capable of coming into contact with and separating from the continuous web at a position on the hand side in the traveling direction and that can give a non-colored marking mark such as a scratch or a die to the continuous web when contacting the continuous web, and the marker. An operating device for actuating the attached member and a detection device for detecting each time the continuous web travels within a predetermined length range. The control device outputs a control signal to the operating device in response to a signal from the knowing device and the detecting device to act as the marking attachment member, and the continuous web on the continuous web is processed into the folding web, and It is equipped with a control device that acts so as to attach a classification mark such as the scratch or the die by contacting the position visible from the outside only when it is taken out from the outlet within a predetermined short length range. I am trying.

(Operation) According to the sorting device for marking according to the present invention, the marking device is operated by the operating device every time the continuous web travels within the predetermined length range, and the sorting mark is applied to the running continuous web. It Further, the portion marked with the sorting mark is visually observed from the outside when the continuous web is sequentially cut by the cutting device and is folded in the zigzag shape by the folding device and is taken out from the exit of the folding part. The operator can sort the continuous folding webs, which are located at possible positions and are continuously taken out, by a predetermined amount in sequence using the marking portion for marking as a guide. Further, since the marking device is adapted to apply a non-colored marking mark to the web, the marking part formed by the marking member is not colored. Since the sorting mark applied to the web is marked by a scratch or a die, it can be sufficiently visually identified even if it is not colored.

(Effect of the Invention) Therefore, according to the sorting sign attaching device in the folding web making machine of the present invention, since the sorting mark applied to the web is not colored, the web on which the sorting mark is applied is used. When you do this (for example, when you unfold a folded web), you don't have to worry about the markings, and you can use them like any other web without markings. There is an effect that it can contribute to the improvement of product value. In addition, since the marking attachment member can apply a non-colored marking for marking such as a scratch or a die to the web, it is said that the coloring agent is replenished like a conventional marking means using an ink marker. There is also an effect that labor is unnecessary.
