[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in a printing factory for newspapers, magazines, books and the like, and is used for winding paper from a paper storage to a rotary press for printing (paper winding for newspaper printing and paper winding for commercial printing). The present invention relates to an improvement in an apparatus for treating a mirror surface of a roll of paper, which is automatically removed from the roll of paper provided on the transport path of (1) and whose outer peripheral surface and both end surfaces are covered with a bump and a mirror paper, respectively.

[0002]

2. Description of the Related Art In general, newspaper printing paper and commercial printing paper that are carried into a printing factory are provided with a bump on the outer peripheral surface thereof to prevent damage during transport and loosening of the tightening.
In addition, both end surfaces are protected by being respectively covered with mirror paper.

[0003] For example, a newspaper printing roll is not shown, but one end face is provided with haptron paper and cardboard.
Completely wrapping by applying haptron paper to the other end surface, winding a wamp (low grade paper) on the outer peripheral surface, bending both end edges toward the end surface side of the rolled paper, and attaching a circular outer paper to the folded portion When stacking webs vertically, the end face of the cardboard is facing down,
The end face of the web is protected by cardboard. Incidentally, in the case of web paper for commercial printing, it may be double-covered with both the paper and the vinyl sheet.

[0004] On the other hand, in a printing factory for newspapers or the like, the web mounted on the web supply reel provided in the paper feeding section of the printing rotary press is preliminarily controlled so as to be continuously fed to the rotary press. A splicing pretreatment has been performed, and the splicing pretreatment is started by cutting and peeling off the mirror paper and the wamp of the web paper, respectively.

[0005] Conventionally, cutting and peeling of the mirror paper covering the end face of the web has been performed manually. That is,
An operator breaks through the center of the roll paper supported horizontally by a forklift or the like with a hand or a cutter, cuts the mirror paper from the center to the outer peripheral edge, and then circles the outer peripheral edge of the mirror paper. By cutting into a shape, the mirror paper is cut and peeled from the web paper. However, the cutting and peeling of the mirror paper by hand causes inefficiencies in work efficiency and causes a rise in labor costs. In addition, since the mirror paper is formed from a plurality of sheets of paper, the mirror paper cannot be easily cut and peeled. was there.

In order to solve the above-mentioned problem of the manual cutting and peeling of the mirror paper of the web paper, the applicant of the present invention first automatically cuts and peels the paper mirror of the web paper. Developed a paper cutting and peeling device.
No.4851 has been published.

That is, in the mirror paper cutting and peeling apparatus, first, the center of the mirror paper covering the end surface of the web is pierced by a triangular void forming member, and the void forming member is inserted into the cylindrical core material of the web. . Next, the gap forming member is pulled back, a part of the member is engaged with the opening peripheral portion formed in the center of the mirror paper, and the mirror paper is floated outward from the end surface of the web. afterwards,
The gap forming member is moved in the radial direction along the end face of the web, and the mirror paper raised from the end face of the web by the gap forming member is cut in the radial direction by a cutter.
Finally, the direction of the gap forming member and the cutter is turned by 90 ° at the outer peripheral edge of the mirror paper, and the mirror paper is cut into a circular shape by rotating the winding paper, and the circular shape is formed by the clamp of the gripping mechanism. The cut paper is clamped and discharged to a predetermined position. This mirror paper cutting / separating apparatus can automatically cut and peel a mirror paper of a rolled paper, and has an excellent practical effect.

[0008]

However, in the above-mentioned paper cutting and separating apparatus, the gap forming member inserted into the cylindrical core material of the paper roll is pulled back outward so that the peripheral edge of the opening of the paper is outward. Although a gap is formed between the end face of the web and the mirror paper by pulling, the gap between the gap forming member and the peripheral edge of the opening of the mirror paper because the gap forming member has a relatively small triangular shape. Failures often occur. Also, when the outer peripheral edge of the mirror paper is substantially cut, the gripping mechanism clamps the peripheral edge of the opening of the mirror paper, so that the mirror paper rolls from the end face of the web before hanging down before the paper is gripped by the clamp. Or something. Of course, since only one portion of the edge of the opening of the mirror paper is clamped by the plate-shaped clamp, the mirror paper may fall off the clamp when the cut and peeled paper is carried out. Was. As described above, in the conventional mirror paper cutting and peeling apparatus, there is a problem that the processing for cutting and peeling the mirror paper of the rolled paper cannot be performed smoothly.

The present invention has been made in view of such a problem, and an object of the present invention is to make it possible to smoothly and reliably perform continuous cutting and peeling processing of a mirror paper covering an end surface of a web. To provide a mirrored surface treatment device for web paper.

In this state, the elevating roller 16 of the web supporting device 2 is driven to rotate, and the web P is rotated about 1.3 times.
Then, the outer peripheral edge of the mirror paper P 'of the web P is sequentially cut over the entire circumference by the cutter blade 30 vibrating with a constant stroke in the vertical direction. At this time, since the cutter blade 30 is vibrating at a constant stroke in the vertical direction by the vibrating section 34, the cutting of the mirror paper P 'is performed extremely smoothly. Also, a part of the lower lifting table 29a is
, The cutter blade 30 cuts the outer peripheral edge of the mirror paper P 'while following the end face of the web P, and the cutter blade 30 is subjected to excessive force. The mirror paper P 'can be cut satisfactorily and smoothly without hanging. Further, during cutting of the mirror paper P ', the holding disc 59
As a result, the mirror paper P 'is pressed and held toward the end face side of the web P, so that the cut mirror paper P' does not roll up from the end face of the web P and hang down, and the cutting of the mirror paper P 'is good. It can be performed reliably. Needless to say, the presser disk 59 can be rotated together with the mirror paper P 'along with the rotation of the web P, so that there is no problem in cutting the mirror paper P'.

When the outer peripheral edge of the mirror paper P 'is cut over the entire circumference by the mirror paper peeling device 4, the driving of the web supporting device 2 is stopped, and the rotation of the web P is stopped, and the cutting is performed. The vibration part 34 of the mechanism 19 is stopped, and the vibration of the cutter blade 30 is stopped. Then, each member of the cutting mechanism 19 (each of the elevating tables 29a, 29b, 29c and the cutter blade 30)
Etc.) return to the home position, and the entire mirror paper peeling device 4 returns to the initial position by the fluid pressure cylinder 22 and the lifting frame 18 while the cutting mechanism 19 moves in the direction away from the web P.

That is, when the mirror paper P 'of the web P is cut and peeled, the gripping pawl 6 inserted into the cylindrical core material P "of the web P by the claw opening / closing fluid pressure cylinder 64 of the gripping mechanism 44.
1 is released, and the entire gripping mechanism 44 is moved by the moving frame 54 and the rodless cylinder 55 of the moving support mechanism 43.
Retreats in a direction away from the end face of the web P (FIG. 1).
4 (A)). Then, the gripper 61 moves toward the mirror paper P 'while the conical portion 61b slides on the inner peripheral surface of the cylindrical core material P "of the web P, and the conical portion 61b moves to the cylindrical core material P". When it comes out of the position, it becomes the open position. As a result, the gripper claws 61 that are completely opened are retracted by hooking the opening peripheral edge formed at the center of the mirror paper P ′ from the inner surface, and retreating several places of the opening peripheral edge of the mirror paper P ′. It is clamped between the presser disk 59 (see FIG. 14B). Since the gripping claw 61 is opened when it retreats, its conical portion 61b is securely locked to the peripheral edge of the opening of the mirror paper P '. As a result, the central portion of the mirror paper P 'is securely and satisfactorily held.

When the center of the mirror paper P 'is clamped between the holding disk 59 and the gripper 61, the revolving arm 41 is horizontally revolved by the hydraulic cylinder 51 of the arm support mechanism 42, and the gripper mechanism 44 is moved. Move from working position to standby position. At this time, since the pressing disc 59 and the gripping claws 61 are used to clamp several places around the opening edge formed in the center of the mirror paper P ', when the cut and peeled mirror paper P' is taken out. Mirror paper P '
Does not fall out of the gripping mechanism 44.

Thereafter, the gripping mechanism 44 is caused to move from the position caused by the link 65 and the oscillating fluid pressure cylinder 66 to the inclined position in the standby position, and the holding disk 59 and the gripping claw 61 are transported to the lower position. Turn to car 9 (Fig. 1
5 (A)).

In this state, the pawl opening / closing hydraulic cylinder 64 is operated to close the gripper 61 at the open position to the closed position, and the pawl forward / backward hydraulic cylinder 62 is operated to operate the bracket 60 and the gripper. The claws 61 are retracted (see FIG. 15B). Then, the mirror paper P ′ held between the holding disk 59 and the gripper 61 becomes the gripper 6.
1 and fall into the mirror paper carrier 9 to be discharged. At this time, the holding disc 59 is in a horizontal posture with respect to the floor surface, and the conical portion 61b of the holding claw 61 enters the opening 59a of the holding disc 59, so that the entire holding claw 61 has a rod shape.
The mirror paper P 'comes off the gripping claws 61 reliably and satisfactorily. In this manner, both the mirror papers P 'of the web P carried into the mirror processing device by the slat conveyor 1 are automatically and simultaneously cut and peeled.

In the above-described embodiment, the mirror paper P 'is cut by the cutter blade 30. However, the mirror paper P' of the rolled paper P double-packed with paper and a vinyl sheet is used. In the case of cutting, the outer peripheral edge of the mirror paper P ′ may be cut by the mirror-surface cutter 39. That is,
When the cutting mechanism 19 moves to the mirror side of the web P and stops at a predetermined position by the mirror stop sensor 35, the mirror cutter 39 is brought into contact with the outer peripheral edge of the mirror paper P 'by the fluid pressure cylinder 40. Then, the web P is rotated by the web support device 2. Then, the outer peripheral edge of the mirror paper P '
The mirror surface cutter 39 cuts the entire circumference.

[0052]

As described above, the mirror surface treating apparatus of the present invention cuts the outer peripheral edge of the mirror paper while pressing and holding the mirror paper covering the end surface of the roll paper toward the end surface side of the roll paper by the pressing disk. Therefore, it is possible to perform the cutting of the mirror paper satisfactorily and reliably without the end plate being rolled up from the end face of the paper roll and sagging when the mirror paper is cut. Needless to say, since the presser disc is rotatable, it rotates together with the web with the rotation of the web, which does not hinder the cutting process of the mirror paper. In addition, the mirror surface treatment apparatus for a paper roll according to the present invention is characterized in that the center portion of the mirror paper is pierced from the opening of the holding disk by a gripper that can be opened and closed, and several positions around the opening peripheral portion formed in the center portion of the mirror paper are pressed. Since the paper is held between the plate and the gripping claws, it is possible to prevent the paper from dropping off during the removal of the cut and peeled paper.
Of course, if the gripping pawl that has broken through the center of the mirror paper is retracted in an open state, the gripping pawl will be securely and satisfactorily locked to the peripheral edge of the opening of the mirror paper. This makes it possible to securely and satisfactorily hold the mirror paper between the holding plate and the gripping claws. Furthermore, the mirror surface treatment apparatus of the web according to the present invention,
Since the holding disc and the gripping claw are configured to be vertically swingable between a raising position facing the mirror paper covering the end surface of the web and a tilting position facing the floor, If the gripper is closed with the disk and the gripper in the tilted position, the mirror paper sandwiched between the holding disk and the gripper will easily come off the gripper and the mirror paper will be removed. Can be reliably and satisfactorily dropped and discharged.
