The present invention relates to an automatic roll paper tailoring device that automatically adjusts the winding paper.

[Conventional technology]

In machines such as newspaper rotary presses that use webs to perform specified processing (printing), in order to continuously feed the webs (rolled base paper), new paper is added to the old base paper (preceding paper) during printing. Base paper(
It is desirable to be able to automatically connect the following paper. For this reason, when connecting the webs, it is necessary to prepare the leading end of the new web, which is the succeeding paper, for splicing, a so-called tailoring operation.

As shown in Figures 8 and 9, this tailoring work includes:
Rolled paper that has scratches, stains, wrinkles, etc. mainly at paper mills or during transportation (6) Cutting and removing defective paper from the main part of the surface layer, and applying side tape (4-force pasting) to the tip of good paper after removing the surface layer. , Cutting the side tape (approximately ■-shaped along 471, cutting the front edge of the paper in the width direction of the ■-shaped top, removing unnecessary paper generated at the leading edge of the good paper section, and cutting the tip adhesive tape (41J or central tab (T-tab)) ( There are various work processes such as pasting of 4z etc.An automatic tailoring device that automatically processes each step or a part of these series of tailoring work has been proposed and put into practical use. The tailoring work that used to be done has also been simplified and labor-saving to a large extent.

FIG. 8 is an explanatory diagram of an example of a conventional automatic tailoring device.
As shown in the figure, in the previous apparatus, the apparatus for carrying out each of the above-mentioned processes was arranged flat with a sewing table (40 marks) as a reference, and the tip of the web (6) was attached to the sewing table (4 marks). Processing (tailoring) in a state where it is fed upward and held.
A format in which this was done was adopted. In other words, the structure and operation of the conventional tailoring device can be briefly explained as follows. First, the paper roll (6) is transported to a predetermined position below the tailoring device by a transport cart, and then axially clamped by chuck end fittings from both sides, and set to a predetermined [tj] via a lifting device decoy. . Next, the skin layer cutting device 40 cuts about 7 to 8 sheets of skin layer paper with dirt, scratches, etc. in the direction of the roll paper axis, and the defective paper portion is cut by a delivery belt (49 and It is discharged to the downstream paper discharge section by the roll 5I, and then the front end of the fasting paper section that has appeared is paid out and fixed onto the tailoring table (A).Then, the tape pasting/cutting device 52 is used to cut the fastening paper section into a substantially V-shaped site 9.
Attach tape (4n) and cut the outside along the side tape pattern.

In addition, the remaining top portion of the tip is cut in the width direction by another unit (not shown), and is also cut by a tab pasting device 53.
Attach the tip adhesive tape (41) and the center tab (421).After the above work is completed, the tip of the first roll will be the delivery bell.
(While being pressed by the roller 491, it is wound onto the paper roll side and fixed to the paper roll side by the central tab (4). With the above steps, the work of making the paper roll is completed.

On the other hand, the cut unnecessary paper is wound up by a winding device (not shown) and discharged out of the apparatus. The conventional roll paper tailoring device performs the above-described series of tailoring operations on a tailoring table (461) installed in a substantially horizontal direction, which requires a large installation area due to the structure of the device. There are various problems that will be explained in the section "Issues to be solved".

[Problem to be solved by the invention]

As explained in the above [Prior Art] section, conventional tailoring devices fix the leading edge of the fasting paper portion onto the tailoring table in a substantially horizontal direction after cutting and removing the skin layer.
A series of tasks related to tailoring, such as pasting tape and cutting, are performed, and structurally, (1) it requires a tailoring table installed approximately horizontally in the direction in which the paper roll runs, which increases the length of the machine. Therefore, a large installation area is required.

(2) Since a wide installation area is required to install the tailoring device, a large paper storage is required, or due to the limitation on the number of machines installed, the amount of prepared winding paper (number) cannot keep up with consumption. There were other problems.

SUMMARY OF THE INVENTION In order to solve these problems, it is an object of the present invention to provide an automatic roll paper finishing device that can achieve smaller size and higher speed.

[Means to solve the problem]

The overall structure is such that the tip of the web after cutting and removing the skin layer paper is reciprocated in a substantially vertical direction while sequentially applying predetermined tailoring to the edges of the paper, making the device more compact and faster (reducing the tailoring time). Plan.

Under the above-mentioned preconditions, the present invention provides the following means (mechanism), particularly regarding the side tape application device and the approximately V-shaped cutting device along the tape.

(1) Roll paper moving means that freely moves the roll paper in the horizontal and vertical directions while maintaining the axis of the roll paper horizontally.

(2) A web rotating means for rotating the web around the axis of the web.

(3) A pair of running bodies that are close to the paper roll and relatively move parallel to the roll axis, and a drive means for the running bodies.

(4) A cutting means that is mounted on the traveling body of item (3) above and whose blade direction is set at a predetermined angle in a substantially vertical plane.

(6) Disposed substantially below the traveling body of item (3) above, grips the leading end of the web, applies a predetermined tension to the front end of the unreeled paper, and unwinds the web and winds it toward the roll side. Paper edge gripping means configured to expand and contract in response to return.

(7) A control means for synchronously controlling the running conditions of the front end of the web by the rotating means in item (2) and the running conditions of the traveling body in item (3).

[For production]

By providing the above means, it becomes possible to automatically perform predetermined paper splicing preparation (tailoring) at the leading end of the web with a small installation space. In other words, the leading edge of the web, which has been transferred and placed in a predetermined device via the web moving means, is moved up and down in the vertical direction by the web rotating means and paper edge gripping means, eliminating the need for a conventional (horizontally installed) tailoring table. Become.

Also, one pair (two sets) each of which is equipped with a rotating means for the roll paper that controls the traveling distance and stopping of the paper edge, a side tape pasting means, and a paper cutting means that cuts along the tape.
By installing a traveling body driving means for relatively moving the traveling body in the width direction of the web, and a synchronization control means for synchronously controlling the traveling body, the traveling body can be moved oppositely to the outside in conjunction with the total unwinding speed of the web. Then, the approximately V-shaped left and right side tapes are tied together, and then the traveling body is moved inward in conjunction with the winding of the paper web back to the roll side, thereby cutting along the side tapes. can.

In this way, the present invention is configured so that the V-shaped left and right side tapes can be applied and cut simultaneously in conjunction with the feeding and rewinding of the paper, so that it is possible to miniaturize the apparatus due to the omission of the tailoring table. Become.

In addition, in contrast to conventional tailoring machines, which unwind the web onto a tailoring table, apply side tape, cut along the tape, perform other processing, and then unwind the tailoring section, In the present invention, side tape is applied to the left and right sides simultaneously while the paper web is being fed out, and cutting along the tape is simultaneously performed on the left and right sides while the tailoring section is being rewound, thereby making it possible to shorten the cycle time of the tailoring work.

FIGS. 2 to 7 show an embodiment of each of the above-mentioned tailoring working means, and the structure and function of each part will be briefly explained below based on the figures.

The web moving device 1 is shown in FIG. 2, tJ! As shown in Fig. J3, the paper roll 60 is suspended on the moving carriage 10 via linear guides arranged in parallel in the direction perpendicular to the axis, and a moving carriage 10 attached to the frame 9, and two sets of linear guides arranged in parallel in the axial direction. A pair of lifting and lowering devices 13 each having a chuck end fitting 12 at the lower end are attached to each moving table 118 and 111). The chuck end fitting 12 is connected to a lifting device 13 and a moving table 11.
They are configured so that they can each be moved in the axial direction through them, and the core tube of the web 6 can be held or removed.

Next, the roll paper rotating device 2 is as shown in FIG. 3, and has a drive device 14 equipped with a pulse motor directly connected to the chuck tip fitting 12 or a detector capable of detecting the rotation angle such as an encoder. Based on the diameter of No. 6 and the rotational speed NO, the sheet end feeding length and rewinding length So can be set as So=πD−No.

As shown in FIG. 4, the pair of traveling bodies 3a and 3b are supported via linear guides 919 on a beam 18 horizontally suspended between both supports 17 of the frame 9, and are formed in opposite directions. One conveyance screw 21 is screwed together. Therefore, both running bodies 3a.

3b can be relatively reciprocated in the width direction (axial direction) of the paper roll using a conveyance screw 21 which is rotated forward and reverse by motor application. The motor can be controlled by using a motor equipped with an encoder or the like, or by using a pulse motor to adjust the Leahy pitch P and rotational speed N of the conveying screw 21.
The moving distance S of the traveling body 3 can be set by (S=P, N).

FIG. 5 is an explanatory diagram of the side tape applying device 7 and the approximately V-shaped cutting device 8 along the tape. The side tape pasting device 7 and the approximately V-shaped cutting device 8 cut the approximately ■-shaped slope (
They are attached to each of the traveling bodies 3a, 3b at a predetermined angle θ with respect to the vertical line in order to match the gradient) angle. The side tape applicator 7 has a tape reel 1
5. It is composed of a tape feeding device 16, a tape pressing roll, a tape cutting device, etc., and the main body plate 24 to which these are attached is attached to the back amplifier table 25 via a moving means (not shown) fixed to the traveling body 3. It moves forward to a predetermined position on the side and then stops. The tip of the adhesive tape 26 attached to the tape reel 15 is wound around a guide roll as an initial condition, and the tape feeding device 1
In this state, the tape feeding device 16 is lowered to insert the tape end into the gap between the paper roll 6 and the tape presser roll. Next, operate the tape presser roll (
forward) to adhere the tip of the tape to the sheet surface via the backup table b. Subsequently, the web 6 is fed out, and in synchronization with this, the traveling bodies 3a and 3b, and therefore the tape applicator 7 on the traveling body, are moved toward the end of the web 6, diagonally relative to the paper. By running it, the adhesive tape is pasted to the front end of the roll 6 in a roughly ■ shape. During this time, the tape feed device 16 moves up and back and waits at the initial position.

Now, a predetermined tension is applied by the braking force of the brake (not shown) of the pressure roll n and the tape reel 15, which is attached to the adhesive tape in a substantially V shape by unwinding it to a predetermined length, and the momentary tension of the knife path is applied. The tape is cut by the forward motion, and is then reliably affixed to the tip by a tape presser roll that moves in the same direction. After applying the adhesive tape, the tape presser roll returns to its original retracted tfL position and waits. Incidentally, the cut end of the adhesive tape 26 on the side of the tape applicator is held as it is in the tape feeding device 16.

As shown in FIG. 5, the approximately V-shaped cutting device 8 is located below the side tape applying device 7 and is attached to the main body plate. The cutter is a disc-shaped rotary cutter 4 that rotates through the application of a motor, and is normally stored in the actual @ position, but by the operation of the cylinder 31, it is pushed out to the position indicated by the dotted chain line in Fig. 5 and engaged. It is now possible to cut paper. After pasting the side tape 47, the traveling bodies 3a, 31), which are stopped at both width ends of the web 6,
It is transferred to the center side in conjunction with the winding of the roll 0111, passes through a path parallel to and opposite to the side tape 47, and is applied to the outside of the tape 47 by a rotary blade supported by the traveling bodies 3a and 3b. Cut along the line.

Next, FIG. 6 shows a paper edge gripping device 4, which is installed at both width ends of the device and moves relatively in the sheet width direction. At the tips of the pair of arms 32, there are provided shafts that can be rotated and stopped, and the tips of the shafts are provided with grips for gripping the sheet. The image in FIG. 6 is a tension roll, which is a dancer that absorbs fluctuations in sheet length due to winding and unwinding of the tip during winding and winding by swinging a pair of arms 36 pivotally connected to the base frame. -It functions as a roll.

As shown in FIG. 7, this lf device is equipped with a control device 37 that synchronously controls the rotation of the web 6 and the movement of the traveling body 3a13b, and the control device 37 controls the running conditions of the leading edge of the web and the width direction of the traveling body. By simultaneously controlling the movement conditions, the relative positions of the running sheets 13a and 3b relative to the fed running paper can be moved diagonally at a predetermined angle.

The processing of the leading end of the web (adhering side tape and cutting along the tape) to form a substantially V-shape is performed by the synchronized running control function, the side tape applying device 7 described above, and the cutting device 8 which cuts the leading end of the good paper portion of the sheet. can.

Further, due to the structure in which two sets of running bodies 3a*3b are installed, processing on the left and right sides of the V shape can be carried out in parallel and at the same time.

Based on the above structure, the tailoring procedure and the functions (actions) of each device will be explained next. The web 6 is carried to the lower center of the automatic web tailoring device via a conveyance trolley, and the lifting device 1
The shaft center of both width ends of the web paper is clamped by the chuck end fittings 12 lowered by the chuck 3, and after being lifted up to a predetermined height, the movable cart 10 is moved to the right side in FIG. 1, and the outer peripheral surface of the web paper is It moves forward until it reaches a predetermined position and then stops.

Next, the sliding arm is lowered and the paper pressing roll 39 pivoted at the tip presses the outer circumferential surface of the paper roll, and in this state, the skin layer cutting device 40, which is waiting at one end of the device, is brought into contact with the outer circumference of the paper roll 1. After that, seven to eight sheets of skin layer paper are cut by running the paper in the axial direction of the web. The skin layer paper (defective paper) cut in this way hangs down as it rotates clockwise in the figure by the drive of the roll rotating device 2, passes between pinch rolls, and is held by the paper leading edge gripping device 4 located below. Chucked and wound. By the above operation, the skin layer paper is wound up, and the continuously unwound paper (good paper portion) is held by the gripping device 4 under a predetermined tension. In this state, the tip adhesive tape 41 (
9) to the center of the sheet. Next, a pair of side tape applicators 3 and presser rolls n, which are waiting at the center of the web, are brought into contact with each other, and the web 6 is fed out, and the traveling bodies 3a and 3b are synchronously moved to both width ends of the sheet. At the same time, side tapes 47 on both sides of the approximately ■ shape are attached.

Subsequently, the web 6 is wound toward the roll side, and the traveling bodies 3a and 3b, which are waiting at both width ends of the web, are caused to travel toward the center in synchronization with the winding speed, contrary to when applying the side tape. The sheet is cut on both sides in a substantially V shape. After cutting the front end of the sheet into a substantially square shape, the remaining square top portion is cut by moving the web front end cutting device in the width direction of the web.

A central tag (T-tab) 42 (9th
(see figure) is attached, and the leading end of the web is stuck to the outer peripheral surface of the roll part by the pressure of the paper pressing roll 39 as the web is wound, thereby preventing the paper edge from coming undone.

Incidentally, the unnecessary paper portion cut off by the trimming of the leading edge of the web is transported together with the skin layer to the position B in FIG. After being clamped by the paper, the chuck 0 of the gripping device 4 is pulled out to both width ends, and the rear skin layer paper falls through the chute 43 to the paper discharge bucket container 45 and is transferred to a predetermined processing vehicle, etc. It will be discharged to. It should be noted that there are various methods other than the above-mentioned embodiments regarding the tailoring procedure, means for driving each part, etc.

Although the angle θ shown in FIG. 7 is the same angle on the left and right sides, it may not be possible to make the angles on the left and right sides the same due to paper passing in a rotary press or the like in a subsequent process. In this case, the transport screw 21
The left and right ratio of -19 may be selected as the tangent ratio of the left and right angles.

Alternatively, it is also possible to provide a reduction gear such as a pulley or a gear between the left and right conveyance screws.

Although the cutting means 8 shown in FIG. 5 is of a rotary knife type, the cutting means is not limited to the rotary knife type and may be modified such as a knife type or a laser type.

The guide for the traveling bodies 3a, 3b shown in FIG. 4 is a υ near guide 919, but is not limited to the linear guide 9.

The roll paper moving means shown in the first cause and FIG. 2 moves the moving means using a linear guide as a guide, but this is also not limited to the linear guide #.
