Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a paper roll that is installed in the transport path of paper rolls from a paper storage to a rotary press, and whose outer circumferential surface and both end faces are covered with a wamp and paper sheets, respectively. The present invention relates to a leaf cutting and peeling device for a roll of paper that automatically cuts and peels the paper.

(Prior Art) Generally, the newspaper roll 6 used in a rotary press has a wamp 7 (low-grade paper) on its outer circumferential surface to prevent it from being damaged during handling or from loosening. So, again,
Both end faces are covered and protected with paper sheets 8, respectively.

That is, as shown in FIG. 23, the roll paper 6 is coated with Hatron paper (not shown) and cardboard 8a on one end surface, and Hatron paper (not shown) on the other end surface, and has a wamp on the outer peripheral surface. By winding the paper and folding both edges inward, and pasting the outer wrapping paper 8b on this part, the paper is completely wrapped, and when stacked vertically, the end face containing the cardboard 8a faces downward. , the end face can be protected by cardboard 8a.

In addition, in FIG. 23, 44 is a cylindrical core material of the web 6;
Reference numeral 5 designates cylindrical metal fittings fitted to both ends of the core material 44.

On the other hand, in a printing factory for newspapers, etc., the web 6 that is attached to a three-pronged web paper supply reel is pretreated for splicing so that it can be continuously fed to a rotary press. This paper splicing pretreatment is performed after the sheets 8 and wamps 7 are cut and peeled, respectively, and before they are attached to the reel.

Conventionally, the cutting and peeling of the paper 8 has been done manually. That is, a worker manually pierces the center of the paper 8 on the web 6 that is supported horizontally with a forklift or the like, and then moves his hand from the center of the paper to the periphery to move the paper 8 in the radial direction. The sheets are sequentially torn, and then the sheets 8 are pulled to tear the peripheral edge portions into a circular shape, thereby cutting and peeling the sheets.

(Problem to be Solved by the Invention) However, there is a problem in that manual cutting and peeling of paper sheets is inefficient and leads to a rise in labor costs.

Another problem is that since it is made of a leaf or multiple sheets of paper, it cannot be easily cut by hand. In particular, the periphery of the paper,
Since the edge of the wamp was folded over, it was even more difficult to cut it by hand.

Furthermore, when cutting and peeling paper by hand, the paper may be completely removed, or a portion of the periphery of the paper may remain on the edge of the web, making it difficult to cut the paper in a constant shape at all times. Could not be peeled off.

However, if the state of cutting and peeling of the paper sheets varies, a problem has arisen in that when cutting and peeling the wamp, it becomes difficult to cut and peel the wamp. In particular, when automatically cutting and peeling the wamp of a web paper using the wamp cutting and peeling processing device disclosed in JP-A No. 63-277161, if the paper is completely removed, there will be no gripping allowance for the wamp. , the wamp could not be cut and peeled.

The present invention was created to solve the above-mentioned problems, and its purpose is to automate the cutting and peeling of paper sheets on a web, and to cut and peel the paper sheets in a constant shape always and reliably. The present invention provides a sheet cutting and peeling device for web paper.

(Means for Solving the Problems) In order to achieve the above object, the paper web cutting and peeling device of the present invention is provided with a web paper sheet cutting and peeling device of the present invention, which uses a web paper sheet whose outer peripheral surface is a wamp and whose both end surfaces are covered with paper sheets. A web support mechanism that supports the web rotatably around its axis; a core detection mechanism that detects the core of the web supported by the web support mechanism; A cutter guide mechanism that is capable of changing the direction and includes a gap forming member that forms an opening in the center of the paper and that slips between the end face of the web and the paper to lift the paper from the end face of the web, and the position of the end face of the web. It is movable in the radial direction and can change direction, cutting the floating part of the paper from the center to the periphery, and cutting the entire periphery of the paper. This device is composed of a cutter mechanism equipped with a cutter that cuts the paper, and a gripping mechanism that captures the paper by grasping the peripheral edge of an opening formed in the center of the paper.

The core detection mechanism is equipped with a piston rod that can come into contact with the paper web, and a fluid pressure cylinder that is movable along the surface of the paper. It is preferable to include a reet switch for detection and a space forming member provided at the tip of the piston rod.

Furthermore, the probe mechanism is arranged to be movable up and down along the edge of the paper, and has a horizontal arm with a cutter guide mechanism and a cutter mechanism arranged on the center line of the paper, and a vertical arm on the arm. The mounting plate, which can be pivoted to the arm and movable along the arm, may also be composed of a pair of upper and lower links that pivot at equal angles with respect to the arm to measure the diameter of the web.

(Function) The core of the paper web supported rotatably around the axis by the paper web support mechanism is detected by the core detection mechanism.

When the core of the web is detected, the gap forming member of the cutter guiding mechanism forms an opening in the center of the paper, and then slips between the opening periphery of the paper and the end face of the web to move the paper to the end face of the web. make it float from the top.

Then, the gap forming member moves from the center of the paper to the periphery, and sequentially lifts the paper from the edge of the web from the center to the periphery, and as a result, the cutter of the cutter mechanism moves the paper from the center to the periphery. The floating portion of the paper is cut off, and the paper is then cut from the center to the periphery.

When the sheet is cut in the radial direction, the gap forming member and the canter change direction by 90 degrees at the peripheral edge of the sheet, and the web rotates once around the axis.

Then, the gap forming member gradually lifts the peripheral edge of the paper from the end surface of the web over the entire circumference, and the cutter cuts off the lifted part of the paper, leaving the peripheral edge of the paper with an edge. Cut around the entire circumference.

Therefore, the paper can always be cut in a constant shape in a good and reliable manner, and complete automation can be achieved.

Furthermore, when the paper is cut by the canter, the gripping mechanism is operated as appropriate to grasp and hold the paper to be cut into discs, so that the cutting can be performed satisfactorily.

Then, when the fluid pressure cylinder 20 is extended and the gap forming member 31 is lightly pressed against the surface of the sheet 8 and the gap forming member 31 is moved to the surface of the paper 8 in this state, the gap forming member 31 is moved. When the sheet 8 reaches the position of the hole in the core material 44 of the web 6, the center of the sheet 8 is pushed and recessed inward, and the piston rod 20a further protrudes accordingly, and this protrusion is detected by the lead switch 21. By this, the core of the web 6 can be detected.

Each arm 19 is disposed on the frame 18 via a drive mechanism 22 so as to be able to reciprocate in the axial direction of the web 6 and to swing up and down as well as in the front and back directions, and when swinging, the tip of the arm 19 passes through the core of the web 6. The drive mechanism 22 also includes a horizontal guide 1-23 disposed on the frame 18 along the web 6, and a horizontal guide 23.

The expanding and contracting action causes the web 6 to reciprocate in the axial direction, the opening of the movable body 27 causes the web 6 to reciprocate in the radial direction, and the direction is changed by 90 degrees when the turntable 29 is driven.

Further, the gap forming member 31 is provided with a plurality of nozzle holes 31a for ejecting compressed air outward in a conical or curved shape when the gap forming member 31 is positioned in the core material 44. Compressed air is supplied to the hole 31a via the flexible pipe 32, etc.! (not shown).

Further, the gap forming member 3 is held under a slight bias by a spring (not shown) so that its long side can take a position parallel to the surface of the sheet 6 as shown in FIG.

Note that the movement stroke of the gap forming member 31 in the axial direction and radial direction of the web 6 allows it to be completely inserted into the core material 44 of the web 6 and to move from the center of the sheet 8 to the periphery. It is set as follows.

The cutter mechanism 4 is disposed on the inner surface of each arm 19, and cuts the floating portion of the paper 8 to cut the paper 8 from the center to the periphery, and also cuts the paper 8 from the center to the periphery. The peripheral edge is cut all the way around.

The direction of the cavity forming portion is changed by 90 degrees in synchronization with the rotational movement of the shaft 31.

The grasping mechanism 5 is disposed on the inner surface of each arm 9 and holds the paper 8 by grasping the opening formed in the center of the paper 8;

Specifically, as shown in FIG. 3, the gripping mechanism 5 is provided on the inner surface of the arm 19, and includes a rotless cylinder 36 mounted on the arm 19 and a movable portion 36 of the rotless cylinder 36.
It consists of a fluid pressure cylinder 37 that is attached to a and expands and contracts in the axial direction of the paper roll 6, and a clamp 38 that is attached to the fluid pressure cylinder 37.

The clamp 38 is fixed to the fluid pressure cylinder 37 via a support piece 39, and includes a fixed clamp plate 38a whose tip end is close to the surface near the center of the sheet, and a fixed clamp plate 38a that can swing and come into contact with the fixed clamp plate 38a. A movable clamp plate 38 is pivotally supported and connected to the piston rod 37a of the hydraulic cylinder 37.
It consists of b.

Each of the clamp plates 38a, 38b is formed in an oval shape, as shown in FIG.

Further, in the clamp 38, the movable clamp plate 38b comes into contact with the fixed clamp plate 38a due to the extension operation of the fluid pressure cylinder 37, and the rolling paper of the gap forming member 31 and the cutter 34 is moved by the beating of the movable portion 36a of the rodless cylinder 36. It moves to the center of the sheet 8 following the movement of the sheet 6 in the radial direction.

Next, the operation of the paper cutting and peeling device will be explained.

The roll 6 completely wrapped with the wamp 7 and the leaf 8 is transferred to the trolley 9 and conveyed between the rollers 12 of the roll support mechanism 1. At this time, the roller 12 has been lowered to a position 4 where it does not prevent the roll paper 6 from entering, and the arm 19 is also at a position where it does not prevent the roll paper 6 from entering (FIG. 2 - dot-dashed line position).
is rising.

The paper roll 6 that has been conveyed between the rollers 12 is moved to the elevating plate 10.
It is rotatably supported and placed between the rollers 12 by the upward movement.

When the web 6 is supported by the web support mechanism 1, the left and right arms J9 are swung downward at a certain angle by the motor 25 to face the sheet 8, and in this state, the arms J9 are further rotated.
9 moves to a certain paper 8 side by the drive of the cart 24, and the paper 8
(See Figure 6). At this time, the cutter 34 and the clamp 38 are in close proximity to the surface of the sheet 8.

Note that the approach of the arm 19 to the paper 8 is controlled by the fluid pressure cylinder 2.
Detected by a proximity switch 46 located at 0.

When the air 419 approaches the paper 8, the hydraulic cylinder 20
Due to the extension operation of , the gap forming member 31 comes into light contact with the surface of the mirror paper 8, and in this state, the arm 19 swings downward and presses the surface of the sheet 8 lightly with the gap forming member 3j- while pressing the core of the web 6. (See Figure 7).

When the gap forming member 31 comes to the position of the holes 1 and 4 of the core material of the paper web 6, the center of the paper 8 is pushed and recessed inward, and the piston rod 20a protrudes accordingly. 2] is detected (see Fig. 8). This allows the core of the web C to be detected.

When the core of the web 6 is detected, high-pressure working fluid is supplied to the hydraulic cylinder 20, which further extends and inserts the gap forming member 31 into the core material 14. At this time, the gap forming member 31
Since it is attached in a biased state at 0a, the core material 4 pierces the center of the paper 8 from the acute-angled base end side while swinging.
Form an opening in the center of the silver paper 8 (see Figure 9).

When the gap forming member 3] completely enters the core material '44,
The fluid pressure cylinder 2o is shortened and the gap forming portion 143!
Return the paper so that its long side is 1° between the end surface of the paper roll 6 and the road surface. In addition, when returning the gap forming member 31, compressed air is ejected outward from the nozzle hole 31a in a conical or curved shape, and the opening periphery of the silver paper 8, which is bent inward by the thrust of the gap forming member 31, is 9 to the outside as shown by the dashed line in FIG. 9, so that the opening periphery of the paper 8 is surely caught on the gap forming member 3.

Then, when the gap forming member 31 returns to the end surface position of the web 6, the cutter 34 is rotated by the drive unit 35, and the sheet 8 is rotated by the drive unit 35.
(See Figure 10). At this time,
When the cutter 34'4 cuts a part of the peripheral edge or the opening peripheral edge of the V-shaped paper 8 located within the forks of the gap forming member 31, the cutter 34'4
The cutter 344 is moved from the center of the mirror paper 8 to the periphery by driving the movable body 27 in the state shown in FIG. At this time, the gap forming member 31 enters between the opening periphery of the paper 8 and the end surface of the paper roll 6, and the claw 52 slides on the end face of the paper roll 6 to sequentially move the paper 8 from the end mf of the paper roll 6 to the seventh skein and the paper roll 6. paper 8
The cutter 34 cuts off the 1-dimension part in one jet (see LIJ and FIG. 12). Therefore, the sheets 8 can be cut in the radial direction without damaging the 6 ends of one roll of paper.

Further, when the gap forming member 31 moves in the radial direction of the web 8, compressed air is ejected from the nozzle hole 3 ], a,
The peripheral edge of the opening of the sheet 8 may be raised from the end surface of the web 8. In this way, the gap forming member 3
1. You can reliably sneak into the room. Furthermore, a gap forming member:
32 and the cutter 34, the central part of the paper 8 is moved by the clamp 38 or cutter 36, and the opening periphery of the silver paper 8 is lifted from the edge of the web 6 by the gap-type one-man member 31. A part of the part is inserted between the nationally specified clamp plate 38,j and the movable clamp plate 38b (
(See Figures 12 and 13).

When the paper 8 is cut to the peripheral edge, the gap forming member 31 and the canter 3.1 are rotated by the turntable 29 to change direction by 90 degrees, and the paper web 6 is rotated in one direction by the paper web support mechanism 1 (the first rotation). (See Figures 12 and 10)
5° Note that when the gap forming member 31 and the cutter 34 change direction, the web 6 also begins to rotate, so the cutter 34 cuts the vicinity of the peripheral edge of the silver paper 8 in an arc shape.

As a result, the gap forming member 31 and the cutter 34 can change direction smoothly.

After the gap forming member 31 and the cutter 34 change direction, the peripheral edge of the paper 8 (at a position of 40 to 5QrrrrI from the circumferential surface of the paper web) is spread around the entire circumference with the edges remaining. Cut across (see Figure 15). At this time, since the gap forming member 31° sequentially lifts the peripheral edge of the sheet 8 from the end surface of the web 6 and cuts it with the cutter 34, there is no possibility that the end surface of the web 6 will be damaged. Further, the leaf 8 is attached to the fixed clamp plate 38a and the movable clamp plate 38 at the peripheral edge of the opening.
It rotates while being interposed between it and b. Furthermore, compressed air may be ejected from the nozzle hole 31a of the gap forming member 31 to lift the peripheral edge of the paper 8 from the end surface of the paper roll 8.

When the peripheral edge of the paper 8 is cut by about 300 degrees, the hydraulic cylinder 37 is extended, and the clamp 38 opens the paper 8.
(See FIGS. 16 and 17) 4 This holds the paper 8 on the end surface of the web 6, making it easier to cut the peripheral edge of the paper 8. In addition, since the paper 8 is grabbed just before the cutting of the paper 8 is finished, even if the paper 8 rotates, the gripping mechanism 5
There is almost no burden on the person.

When the paper 8 is cut along the entire circumference, the web 6
, each arm 19 moves in the direction away from the end surface of the web 6 to completely peel off the silver paper 8 from the web 6, and then the arm 19 swings backward and the clamp 3
8 releases the clamped state of the paper 8 (see FIG. 18). 29, the sheets 8 fall from the arm 19 and are stocked at a predetermined position.

In this way, the paper sheets 8 on both ends of the web 6 are automatically and simultaneously cut and peeled off in a predetermined shape leaving edges.

The operations of each mechanism IT213+4T are all controlled by a control device (not shown), depending on the set beliefs.

I. In the above embodiment, the probe mechanism 2 (, the fluid cylinder 20, the reed switch 21, and the gap forming member 31 were constructed, but the present invention is not limited to this).
As long as it is possible to detect the core of the web (3), it may be of any structure and type.

For example, the core probe mechanism 2 may be configured as shown in FIG. 19 and FIG. 2C. That is, this probe mechanism 2 is j)
) It is supported so that it can be lowered freely on a rail 40 installed in an upright position, and when lowered along the surface of the sheet 8, a gap forming member 31 and a canter 3 are located at a location on the center line of the silver paper 8.
4 and classic: horizontal arm 19' with 38
and 2. A pair of upper and lower links 41 are attached to the arm 19' so as to be able to swing downwardly and be movably fixed to the arm co 9', and swing at equal angles with respect to the arm 19'. The tip of the lower link 41 is pivoted by an appropriate means to the lower end position of the web 6 supported by the roller 12, and the fluid pressure cylinder 42 is expanded and retracted. When operated, each link 41 swings synchronously at equal angles with respect to the arm 19', and the base end of the link 41 slides on the arm 19', and as a result, the arm 19' moves onto the rail 4o. It is designed to go up and down along the way.

Therefore, when the tip of the lower link 4F is pivoted to the lower end 1 of the web 6 and the tip of the upper link 41 is brought into contact with the upper end of the web 6, the tip of the arm 19' automatically
It will come to the position of the core.

Note that the gap forming member 31. Of course, the cutter 34 and the clamp 38 are movable relative to the arm 19'. In addition, the core probe mechanism 2 has a left and right pair, and is raised to a position that does not obstruct the loading and unloading of the web 6 when loading and unloading the web 6. In the above embodiment, the gap forming member 31 is used to hold the sheet 8. Although the core of the web 6 is searched for by swinging the arm 19 while pressing lightly on the surface, the present invention is not limited to 29; for example, a gap forming member; 7.1
Alternatively, the arm 11] may be fixed at a position r facing the core of the winding paper 6, and the empty β: , ;,
: Forming member; 3] may be moved along the arm 19 to search for the core, or the gap forming member; You may also press lightly.

In the above embodiment, the arm]-9 was arranged at the rear position of the paper roll 6, but the present invention is not limited to this.
For example, a pair of arms] 9 may be disposed above the web 6.

That is, as shown in FIGS. 21 and 22, the water screens 1 to 23 and the trolley 2.1 are arranged on two sides of the axis of one roll of paper 6, and the rails 2. , the deep center structure 2, the cutter guide machine groove], the six-cutter mechanism 4, and the gripping mechanism 5 may be mounted on the arm 19 so that it can move up and down and swing freely from a horizontal position to a vertical position. .

In this case, when the arm 19 is swung from the horizontal position to the vertical position, the arm 19 will be located on the center line of the sheet 8.

Therefore, when the arm 19 is lowered along the rail 43 in a vertical position, the arm 19 passes over the core of the web 6,
The core of the web 6 can be detected by the core probe mechanism 2, and the paper 8 can be cut and peeled by operating the cutter guiding mechanism 3, the cutter mechanism 1, and the gripping mechanism 5.

In the above embodiment, the cutter guiding mechanism 3 is connected to the gap forming member 3.

In the above embodiment, the cutter mechanism 4 is composed of a circular cutter 34, a drive unit 35, etc., but the present invention is not limited to this, and the cutter mechanism 4 is configured by cutting the floating portion of the paper 8 to cut the leaf. Any structure and type may be used as long as it can cut the paper 8 from the center to the periphery and also cut the entire periphery of the paper 8.

In the above embodiment, the gripping mechanism 5 is composed of the clamp 38, the fluid cylinder 37, etc., but the present invention is not limited to this, and the opening peripheral edge formed in the center of the sheet 8. It may be of any structure and type as long as it can grip and hold the silver paper 8.

In the above embodiment, after cutting the paper 8 in the radial direction, the web 6 is rotated to cut the entire circumference of the silver paper 8. However, since the web 6 is not rotated, the cutter 34
The silver paper 8 may be cut one step at a time by winding it up and moving it in the radial direction of the paper 6.3 In this way, the paper 8 is cut in a spiral shape from the center to the periphery. Cut off, go with f.

In the embodiment described above, the clamp 38 is used to grasp the opening periphery of the paper 8 when the periphery of the paper 8 is cut by about 300 degrees, but before that, the clamp 38 is used to grasp the opening periphery of the paper 8. You can also grab it.

In the above embodiment, the cutter guiding mechanism 3 and the cutter mechanism 4 are respectively disposed at both ends of the web 6 to simultaneously cut and peel off the sheets 8 at both ends of the web 6. However, the invention is not limited to this, and the cutter guide mechanism 3, cutter mechanism 4, etc. may be provided only on one side of the paper roll 6, and the paper 8 may be cut and peeled from one side. In this case, the web 6 must be rotatably supported, or the cutter guiding mechanism 3 etc. must be configured to be movable from one end surface side of the paper roll 6 to the other end surface side. Although the paper cutting and peeling device was installed by M, for example, it was installed in the wamp cutting and peeling processing device disclosed in Japanese Patent Application Laid-Open No. 63-277161, and cutting and peeling of the wamp 7 of the web 6 and the leaf paper 8 was carried out. You may choose to do it at the same location.

(Effects of the Invention) As mentioned above, the paper cutting and peeling device of the present invention can automate all the cutting and peeling of sheets, improving work efficiency and reducing the number of workers, thereby reducing personnel costs. It is possible to reduce the amount. In particular, when the cutter guide mechanism, cutter mechanism, etc. are arranged at both ends of the web, both sheets can be cut and peeled at the same time, further improving work efficiency.

In addition, because the cutting and peeling of the leaf paper has been mechanized, the leaf paper is one of the multiple attacks.
Even if it is made of paper, it can be cut well and reliably.

Furthermore, since the cutting and peeling of the leaf paper has been mechanized, it is possible to cut and peel the leaf paper in a constant shape at all times, compared to the manual cutting and peeling using rough sanding. It also becomes easier to do.

Particularly, when the paper is cut and peeled with the edges remaining, cutting and peeling of the wamp by a machine can also be performed reliably and favorably.
