Abstract

PURPOSE:To make a cutter guide port surely formable in desired depth irrespective of tightness of winding and existence of surface irregularity of roll paper sheet by allowing a cavity forming member to get into the roll paper sheet from a no-stop end part. CONSTITUTION:In the point of time a cutter guide port is formed, rotation of roll paper sheet 1 is stopped. Next, in a cutter member 39 provided with a guide part 39a possible in contact with a roll paper sheet surface and a cutting blade part 39b vertically rising up from a base end side location of the guide part 39a, a point end part of the guide part 39a is inserted below the second layer part 12 or the third layer part 13 and further the cutting blade part 39b is crossed with a cut layer part 1e which is a roll paper sheet part on the guide part 39a. Under this condition, the cut layer part 1e is cut over the total width by moving the cutter in a width direction of the roll paper sheet 1.

Description

[Detailed description of the invention]

[Industrial Application Field] Generally, in order to continuously feed paper into a rotary press, it is necessary to pre-process the web for paper splicing. The present invention is a method for carrying out a waste paper process for rolled paper, which is an initial step in such pretreatment, in which a rolled paper whose starting end is fixed with an adhesive tape or the like except for at least the side edge part is lined. It is about the method. [Prior Art] In general, pretreatment for paper splicing is a waste paper process (19 Figure), a cutting process in which an appropriate amount of the waste paper end portion of the web 1 is pulled out, the soiled part 1' is removed, and a substantially V-shaped paper splicing end 1c is formed (
(Fig. 20), a tape pasting step (Fig. 21) in which a tab 3 and adhesive tape 4 for paper splicing are pasted to this paper splicing end 1c, and this tab 3 fixes the paper splicing end 1c to the surface of the web 1. This process is carried out through the paper splicing end fixing process (Fig. 22), which is the initial process of waste paper process, as described in Japanese Patent Publication No. 1-2.
The technique disclosed in Japanese Patent No. 4698 is well known. In other words, the paper waste paper method disclosed in the publication is as follows:
By suctioning a suitable part of the first layer portion of the web paper over its entire width, it is lifted from the second layer portion, and by pressing a saw blade-shaped cutter member over the entire width of the lifted layer to be cut. , so that they can be separated.

[Problem to be solved by the invention]

However, since the winding tightness of each roll of paper is not constant, if the first winding tightness is high, the first layer cannot be kept sufficiently floating, which may damage the paper roll below the layer to be cut or There is a possibility that the layer portion cannot be cut properly. On the other hand, if the winding is not tightly tightened, there is a risk that not only the first layer but also the layer below it will be sucked in. If there are multiple layers to be cut, the saw blade-like cutter The method of pressing the member cannot reliably cut the layer to be cut. Incidentally, depending on handling such as unloading, unevenness may occur on the surface layer of the paper roll. In such cases, even if the seaming tightness is appropriate, the amount of lifting of the layer to be cut may be uniform in the width direction. Otherwise, there is a risk that cutting across the entire width may not be performed satisfactorily. As described above, in the conventional waste paper method, depending on the properties of the paper roll, the layer to be cut cannot be reliably cut, and complete automation cannot be expected. The present invention has been made in view of this point. It is an object of the present invention to provide a completely automated scrap paper method that can reliably line a web regardless of the properties of the web.

[Means for Solving the Problem 1] The waste paper method of the present invention that solves this problem involves rolling paper whose starting end is fixed except for at least the side end portion.
By rotating the gap forming member in the lined paper direction opposite to the winding direction while holding the gap forming member in a relatively slidable manner on the peripheral surface of the side end portion, the gap forming member is attached to the circumferential surface of the side end portion. Insert it from the stuck end under the first layer of the web,
By further rotating the web by a predetermined amount in the ruled paper direction from the time when this penetration is completed, the gap forming member is moved between the second layer portion and the third layer portion of the web paper or between the third layer portion and the fourth layer portion. A cutter guide opening opening at the side end surface of the web is formed between the layer parts by the presence of a gap forming member, and the rotation of the web is stopped at the time when the cutter guide opening is formed. Above, a cutter member having a guide part that can be attached to the paper roll surface and a cutting blade part rising vertically from the proximal part of the cutter member is inserted so that the tip part of the guide part is inserted from the cutter guide opening to the bottom of the second layer part or the cutter member. By inserting the cutting blade under the third layer and moving it in the width direction of the first roll with the cutting blade intersecting the layer to be cut, which is the roll of paper on the guiding part, the layer to be cut can be made to have the full width. This is to cut across the entire length. When the gap forming member starts to slip under the non-fastened end portion, it is preferable to blow gas onto the non-fastened end portion so as to turn it up. [Function] Since the gap forming member is inserted into the web from the non-attached end portion, the cutter guiding opening can be reliably formed at the desired depth regardless of the winding tightness of one roll of paper or the presence or absence of surface irregularities. You can keep it. In particular, if the non-fastened end portion is turned up by gas injection, the gap forming member can be inserted more reliably. In this way, the cutter guide port can be reliably formed, the guide portion of the cutter member can be inserted through the cutter guide port, and the portion of the layer to be cut that is subjected to the cutting action by the cutting blade portion and the portion of the paper web immediately below the cut portion can be separated. Since separation is performed by the guide section prior to the cutting action, only the layer to be cut portion can be reliably cut regardless of the degree of winding of the paper web. Moreover, even if the surface layer of one roll of paper has irregularities, the layer to be cut on the guiding section forms two or three layers, so the tip of the guiding section will not break through the layer to be cut due to the unevenness. Therefore, the layer to be cut can be reliably cut over its entire width. Therefore, regardless of the properties of the paper roll, it is possible to always properly and reliably scrape paper, and complete automation can be achieved. [Example] An example of the present invention will be described below. First, the configuration of a thin paper device for implementing the present invention will be described. As shown in FIGS. 11 and 12, this thin paper device 11 forms a part of a paper splicing pre-processing machine. That is, in this pre-processing machine, after the thin paper device 11 performs waste paper (thin paper process) on the web 1, the paper splicing edge forming device 12 subsequently scrapes the thin paper end portion of the web 1 onto the processing table 1.
3, to separate the soiled portion 1' and form the paper splicing end 1c (cutting process).
The tab 3 and adhesive tape 4 for paper splicing are attached to c (tape attachment process), and at the same time, the soiled portion 1' is disposed of by the waste paper processing device 14, and finally, the web 1 is attached to the tab. The device 15 fixes the paper splicing end 1c using the tab 3 (
It is configured to carry out the paper splicing end proper attachment process). Note that each device is automatically controlled by a control device 16. The thin paper device 11 includes a one-roll paper support mechanism 21, a cutter guide mechanism 22, and a cutter mechanism 23, as shown in FIGS. 11 to 13. As shown in FIGS. 11 to 13, the paper roll support mechanism 21 includes a pair of left and right arms 24.24 that can swing up and down, and a rotating mechanism that is provided at the tip of the arms 24.24 and that can move forward and backward in opposite directions. It is provided with a support shaft 25.25 and a roll drive mechanism (not shown) that drives the rotation support shaft 25 in forward and reverse directions. According to this support mechanism 21, one roll of paper 1 can be supported by the rotating spindles 25 and 25 fitted into the core from both sides, and by driving the one-turn spindle 25, it can be forcibly rotated in forward and reverse directions. It has become. Note that the supporting position of the web 1 by the support mechanism 21 can be freely adjusted by swinging the arm 24°24. The adjustment is made according to the diameter of the web 1. Also. When transporting the web 1 that has been pretreated for paper splicing into a rotary press, the arm 24 is lowered to a position where one web 1 is placed on the trolley 26, and then the arm 24 is lowered to the position where one web 1 is placed on the trolley 26, and then the arm 24 is moved to the rotating support shaft 25. 25 is withdrawn from the core of the web 1, and the arm 24 is further raised to a position where it does not interfere with the movement of the web 1 by the trolley 26 (the chain line position in FIG. 12). By the way, the starting end 1a of one roll of paper 1 is shown in FIGS. 11 and 1.
As shown in FIG. 3, it has a trapezoidal shape with both side ends cut off, and is fixed with adhesive tape 2 at several points in the center except for the two side ends 1b and 1b. In addition, in the following explanation. The first layer portion 11 of the web 1 refers to the portion of the web extending from the starting end 1a to the point where it is fixed with the tape 2, and the second layer portion 1□ refers to the portion that extends entirely below the first layer portion 11. The overlapping web portion, and the third layer portion 13 refer to the web portion that completely overlaps under the second layer portion 1□. As shown in FIGS. 13 to 15, the cutter guiding mechanism 22 is disposed directly above one end of the web 1, and includes a cylinder 28 attached to an upper frame 27 in a hanging manner, and a lower end of the cylinder 28. A gap forming member 32 is attached to the bracket 29 via a hinge 30 and an adjustment bolt 31, and a penetration detector 33 and a nozzle 34 are attached to the bracket 29. As shown in FIGS. 14 and 15, the gap forming member 32 has a sinking action portion 3 that can be attached to the curved side end portion of the web 1.
2a, a gap forming effect part 32b that gently continues and bulges out from the diving effect part 32a, and the gap forming effect part 32b.
It has a cutter guide portion 32c continuous from the cutter guide portion 32c. The penetrating action portion 32a is formed into a thin blade shape so that it can easily slip under the non-fastening end portion lb, which is the side end portion of the starting end portion 1a of one roll of paper. The cutter guide portion 32c is slightly curved along the surface of the paper roll 1. Gap formation action section 32
The amount of protrusion from the surface of the cutter guide portion 32c (b) is generally approximately 1.5 to 2 cm. This gap forming member 32 is lowered by the extension operation of the cylinder 28, and the slip-in action section 32a and the cutter guide section 32c are inserted into the web 1.
It is adapted to be attached to the surface of one end of the. As shown in FIGS. 3 and 14, the penetration detector 33 is composed of a phototube disposed directly above the cutter guide portion 32c, and the gap forming member 32 is inserted between the non-attached end portion 1b and the first layer portion. 11 Detects that the robot has crawled under the ground. In order to ensure such detection, the gap forming member 32 is painted black. When the penetration detector 33 detects that the gap forming member 32 has penetrated, a timer is activated by the detection signal.
The web drive mechanism, and therefore the rotation of the web 1, is stopped after a predetermined period of time. In this example,
1 from the time when the web 1 completes insertion into the gap forming member 32
The timer time is set so that the rotation is made by an appropriate amount within the range of more than 2 rotations but not more than 2 rotations. As shown in FIGS. 1, 2, and 14, the nozzle 34 is configured to lift the non-attached end portion 1b of one roll of paper 1 by ejecting pressurized gas such as compressed air toward it. ing. As shown in FIGS. 13, 16, and 17, the cutter mechanism 23 includes a movable body 35 supported by an upper frame 27 so as to be able to reciprocate in the axial direction of the web 1, and a movable body 35 attached to the movable body 35 in a hanging manner. , a cylinder 36 attached thereto, and a cutter member 39 attached to the lower end of the cylinder 36 via a bracket 37 and a hinge 38. The cutter member 39, as shown in FIGS. 16 and 17,
It has a tapered guide section 39a and a cutting blade section 39b vertically rising from the proximal end of the guide section 39a, and the movable body 35 is driven by an appropriate driving means to cut the web 1. It can be moved in the width direction. Further, the cutter member 39 is configured to be lowered by the extension operation of the cylinder 36 to a position where the guide portion 39a comes into contact with the paper roll surface. Note that the cutter member 39
is biased in the direction of adhering to the paper roll 1 by a leaf spring 40, and is designed so that even if the surface layer of the paper roll 1 has irregularities, it can be slid while following the irregularities well. Next, the method of the present invention will be specifically explained using the ruled paper device [11]. First, with the gap forming member 32 attached to the side edge curve of the web 1, the web 1 is moved in the waste paper direction opposite to the tightening direction (
direction). Due to the rotation of the web 1, the gap forming member 32 slides relatively on the surface of the first layer portion 11, so that the gap forming member 32 slides under the surface of the first layer portion 11.
a slips into the first layer portion 11 from the non-fastened end portion 1b (FIGS. 1 and 2). At this time, by injecting gas from the nozzle 34 to flip up the non-locking end portion 1b, the sinking action portion 32a can sink more easily. When the diving action portion 32a sinks in, the gap forming portion 32b and the cutter guide portion 32c subsequently sink in (FIGS. 3 and 4). At this time, the void forming part 32b expands from the surface of the web 1, but since it is connected to the submergence acting part 32a, it smoothly submerges under the first layer portion 1□. When the gap forming member 32 has completely penetrated under the first layer portion 11, the penetration detector 33 detects this and the timer is activated, and the rotation of the web 1 in the direction of waste paper continues until a predetermined period of time elapses. Continued. As the web 1 continues to rotate, the gap forming member 32 moves relatively from below the first layer portion 11 to below the first layer portion 1□, and when the first web 1 is stopped, it moves to the second layer portion 1□. A cutter guiding port 1d that opens at the side end surface of the web 1 is formed by the gap forming portion 32b at a distance from the third layer portion 13 (FIGS. 5 and 6). When the cutter guiding port 1d is formed and the web 1 is stopped, the cutter member 39 is lowered and the guiding portion 39a is placed on the upper surface of the cutter guide portion 32c of the gap forming member 32 and outside the web 1. It is attached onto the exposed portion (FIGS. 7 and 8). In this state, when the cutter member 39 is moved in the width direction of the web 1, the guiding portion 39a first slides on the cutter guide portion 32c and is inserted under the second layer portion 1□ from the cutter guiding opening 1d. At this time, gas may be ejected from the nozzle 34 toward the cutter guide port 1d. The layer portion 1e to be cut on the cutter guide portion 32c and the third layer portion 13 therebelow are reliably separated, and the subsequent cutting action can be performed better. And cutter member 3
9, the layer portion 1e to be cut is cut by the cutting blade portion 39b that intersects with the layer portion 1e (FIGS. 9 and 10).
figure). At this time, as shown in FIG. 10, the guide portion 39a advances under the uncut layer portion le prior to the cutting action by the cutting blade portion 39b.
The cutting action is performed in a state where e and the third layer portion 13 directly below are reliably separated. Therefore, regardless of the winding tightness of the web 1, only the layer portion 1e to be cut can be reliably cut without damaging the third layer portion 13. By the way, since the guide portion 39a slides on the third layer portion 13, if the sliding surface is uneven, the guide portion 39a slides on the third layer portion 13.
There is a possibility that it may break through the portion 1e and come out on top of the portion 1e. In this state, cutting by the cutting blade portion 39b is not performed. However, the layer portion 1e to be cut is not one layer but two layers 1□, 1
2, there is no such possibility. Therefore, regardless of the winding tightness of the web 1 or the presence or absence of irregularities in the surface layer portion, the layer portion 1e to be cut can be reliably cut over its entire width, and the web 1 can be made into a thin paper in good condition. Note that the cutter guide port 1d is formed at the third layer portion 13.
and the fourth layer portion, and may be set as appropriate depending on conditions such as the properties of the web 1. The adjustment can be made by changing the time set by the timer. [Effects of the Invention] As can be easily understood from the above explanation, according to the present invention, thin paper can always be produced in a good and reliable manner regardless of the properties of the web, and complete automation can be achieved. In addition, since the soiled part that is separated in the cutting process generally extends from the first layer to the second or third layer, when cutting only the first layer as in the conventional method, In comparison, the amount of pulling out of the banknote end portion in the cutting step performed subsequent to the lined paper step can be reduced, and the efficiency of the entire preprocessing can be improved.
