[0002]

2. Description of the Related Art Generally, a commercial printing paper roll or a newspaper printing paper roll that is carried into a printing plant has end plates on both end surfaces in order to prevent damage and loosening during transportation.
The outer peripheral surface is covered with a hump and protected. A cardboard or a vinyl sheet is usually used for the end plate and the wamp. Specifically, the paper roll is entirely covered with only the cardboard, or is double covered with the cardboard and the vinyl sheet to be completely packaged.

By the way, in a printing factory for magazines and newspapers,
In the preparatory process before feeding the web into the printing press, the removal process of the end plate and the wrap of the web is performed.

Thus, the removal process of the end plate and the wamp has hitherto been performed manually, but in recent years, there has been a growing demand for automation thereof, and development of an automatic end plate removing device and an automatic wamp removing device has been promoted. ing.

Conventionally, as this type of device, for example, a roll paper mirror surface treatment device disclosed in Japanese Patent Laid-Open No. 7-76329 and a paper roll protective paper removing device disclosed in Japanese Patent Laid-Open No. 5-139578 are known. ing.

That is, the former mirror surface processing apparatus, as shown in FIG. 37, has a supporting and rotating unit 110 for rotatably supporting the paper P and a diameter measuring unit 1 for measuring the diameter of the paper P.
11 and a cutting unit 112 for cutting the end plate of the paper roll P
And a gripping unloading unit 113 for unloading the cut mirror paper of the paper P to the outside of the machine, and a support traveling unit 114 for movably supporting the cutting unit 112, the gripping unloading unit 113, and the like. Motion unit 11
The outer peripheral edge portion of the end plate of the paper P supported by 0 is cut along the entire circumference by the cutting unit 112, and the cut end plate is held by the gripping carry-out unit 113 and discharged out of the machine. is there.

Further, in the latter protective paper removing device, as shown in FIG. 38, a paper roll support device 115 for rotatably supporting the paper web P, a frame 116 installed in the vicinity of the paper roll support device 115, and an elevating frame.

[0009]

However, since the mirror surface treating device and the protective paper removing device are separately installed in the transport path of the paper roll to the rotary press, the end plate removing process and the wamp removing process are performed. Since it has to be performed separately in different places, there is a problem that it is difficult to improve work efficiency. This is because the roll paper that has been subjected to the mirror plate removal processing by the mirror surface treatment device is transported to the protection paper removal device by using a conveyor or a roll transport vehicle, and supported by the roll support device of the protection paper removal device. This is because the wamp removal process is performed. However, if the mirror surface processing device and the protective paper removing device are separately installed, a supporting device for supporting the paper roll (a supporting and rotating unit or a paper roll supporting device) is also required, which causes a problem that the cost increases. is there.

The mirror surface processing device and the protective paper removing device are
Both of them are configured to cut and peel off the end plate and the wamp from the upper side of the roll paper supported by the support rotation unit and the roll paper support device. However, there is a problem in that the entire unit or the entire apparatus must be moved up and down to move up and down, which leads to an increase in the size of the apparatus itself and a complicated structure.

The present invention was created in order to solve the above problems, and its purpose is to efficiently remove the end plate and the wamp of the paper roll, and to greatly reduce the size and cost of the device itself. It is an object of the present invention to provide an end plate / wamp removing device for a paper roll, which is capable of reducing the number of windings.

[0012]

In order to achieve the above-mentioned object, a device for removing end plate / wamp of a paper roll according to the present invention comprises a paper roll whose both end surfaces are covered with end plates and whose outer peripheral surface is covered with a wamp. A roll paper support device having two parallel support rollers that are rotatably supported around it, and a mirror plate cutting device that is disposed in the vicinity of the support rollers and cuts and peels the roll paper end plate supported by the support rollers from below. A peeling device, and a one-p cutting and peeling device that is disposed in the vicinity of the support roller and cuts and peels the one-punch of the paper roll supported by the support roller from the lower side. It is inserted between the end surface of the paper roll main body and the end plate at the lower part, and is movable in the radial direction and the width direction of the paper roll that cuts the outer peripheral edge portion of the end plate around the entire circumference by rotation of the paper roll by the paper roll support device. Mosquito End plate cutter mechanism having a cutting blade, and an end plate processing mechanism that holds the cut end plate and discharges the end plate, and the one-punch cutting and peeling device is provided with a main body of the web at the lower part of the web. A gap forming mechanism that forms a gap between the end of the wamp, and a cutter mechanism for a wamp that includes a cutter blade that is inserted in the gap and that cuts the wamp across the width direction and that can travel in the width direction of the web. The cut wamp is wound up in a round shape, and then crushed into a flat shape and discharged.

[0013]

[Operation] The roll of paper with the end plate / wamp that has rolled from the exit of the paper storage to the end plate / wamp removing device side rides on the support roller of the paper support device and then collides with the roller of the stopper / pusher mechanism to receive it. And is placed on the support roller. When the paper roll is supported by the support roller, the end plate cutter mechanism of the end plate cutting and peeling device and the paper roll support device are activated, and the outer edge of the end plate on both end faces of the web end is covered by the cutter blade of the end plate cutter mechanism over the entire circumference. Be disconnected.
When the end plate is completely cut, the end plate cutting mechanism of the end plate cutting / peeling device is activated, and the end plate cut by the clamp is pinched and separated from the web main body, and then delivered to the discharge roller to be discharged to the discharge roller. Is discharged by. After the end plate of the paper roll is removed, the gap forming mechanism of the one-piece cutting and peeling device is activated to form a gap between the main body of the paper roll and the end of the one-piece web in the lower portion of the paper roll. When a gap is formed between the main body of the paper roll and the end of the wipe, the cutter mechanism for the wipe of the wipe cutting and peeling device is activated, and the wipe is cut by the cutter blade across the width. When the wamp is cut, the wamp processing mechanism is actuated, and the wamp cut by the winding mechanism is rolled up into a round shape and then crushed into a flat shape by the pressing mechanism and discharged. In this way,
The end plate that covers both end surfaces of the web and the wamp that covers the outer peripheral surface are removed.

In the end plate / wamp removing device of the present invention, since the end plate removing process and the wamp removing process can be performed continuously at the same place, the work efficiency can be greatly improved. Further, since the end plate cutting / peeling device and the wamp cutting / peeling device are configured to cut the end plate and the wamp at the lower portion of the paper roll supported on the support roller, the end plate and the wamp are cut regardless of the diameter of the web paper. The cutting positions are substantially constant. As a result, it is not necessary to move the entire apparatus up and down according to the diameter of the paper roll, and the apparatus itself can be made significantly compact and the cost can be reduced. Needless to say, only one roll supporting device is required, and the cost can be further reduced.

This is a positioning roller that can be brought into contact with the end plate Pa.

Thus, the end plate cutter mechanism 16 is
The outer peripheral edge portion of the end plate Pa of the paper roll P is cut around the entire circumference by being drive-controlled as follows. That is, when the paper roll P is supported by the support rollers 7 of the paper roll support device 1, the traveling base 20 moves to the end surface side of the paper roll P, and the entire end plate cutter mechanism 16 waiting at the outer position of the paper roll P is removed. The paper P is moved to the end surface side (see FIG. 5). When the end plate cutter mechanism 16 moves to the web P side and the positioning roller 46 contacts the end plate Pa of the web P, the traveling platform 2
0 stops moving (dashed line position in FIG. 5). At this time, the cutter blade 29 is several mm from the end plate Pa of the paper roll P.
Is located only inside and is located at a position apart from the end of the outer peripheral surface of the paper P by a certain distance (see FIG. 10). Next, the cutter blade 29 is inserted into the gap while detecting the gap between the end face of the web main body P ′ and the end plate Pa by the cutter blade 29, the end face detection fluid pressure cylinder 30 and the like. That is, the end face detection fluid pressure cylinder 30 is used for the upper cutter table 2
8a is moved up and down and the cutter blade 29 is pierced to the outer peripheral surface of the paper roll P (see FIG. 11). When the reed switch of the end face detection fluid pressure cylinder 30 is not turned on due to the stab of the cutter blade 29, the traveling frame 20 is moved by a slight amount to move the cutter blade 29 toward the end plate Pa side of the paper roll P.
After moving 5 mm, the cutter blade 29 is again moved up and down by the end face detection fluid pressure cylinder 30 in this state to wind the paper P.
Pierce the outer peripheral surface of. In this way, the cutter blade 29 is moved toward the end plate Pa side of the paper roll P by 0.5 mm until the reed switch of the end face detection fluid pressure cylinder 30 is turned on, and the outer peripheral surface of the paper roll P is sequentially stabbed and the paper roll main body is inserted. The gap between the end surface of P'and the end plate Pa is detected. When the reed switch of the end face detection fluid pressure cylinder 30 is turned on by the piercing operation of the cutter blade 29, the cutter blade 29 is inserted between the web main body P ′ and the end plate Pa (FIG. 12 (A)). And (B)). When the cutter blade 29 penetrates between the web main body P ′ and the end plate Pa, the fluid pressure cylinder 31 causes the upper cutter table 28a and the intermediate cutter table 28b to move upward, and the cutter blade 29 moves to the web main body P. ′ And the end plate Pa are penetrated further deeply (see FIGS. 13A and 13B). afterwards,
The tilting fluid pressure cylinder 32 operates, and the cutter blade 29 is tilted at 45 ° while penetrating between the end surface of the paper roll body P ′ and the end plate Pa (see FIG. 14). As a result, the cut portion of the portion where the cutter blade 29 has penetrated becomes large. When the cutter blade 29 tilts, the crank mechanism 33 operates to reciprocate the cutter bases 28a, 28b, 28c in the vertical direction, and the cutter blade 29 reciprocates with a constant stroke. Further, the engagement between the piston rod of the fixing fluid pressure cylinder 25 and the support base 26 is released, and the support base 26 becomes free (swingable). In this state, the support roller 7 of the paper roll support device 1 rotates to slowly rotate the paper roll P in the direction of the arrow in FIG. As a result, the outer peripheral edge of the end plate Pa is sequentially cut by the cutter blade 29. At this time, since the cutter blade 29 is swung by the crank mechanism 33, the end plate Pa is cut very smoothly. Further, since the support base 26 is in a free state (swingable), the cutter blade 29 cuts the outer peripheral edge portion of the end plate Pa while following the end surface of the web main body P '. End plate P
A will be cut well. When the outer peripheral edge portion of the end plate Pa is cut by about 3/4, the support frame 26 is fixed by the fixing fluid pressure cylinder 25 in a position parallel to the traveling frame 20, and the traveling frame 20 is slightly removed from the web P. It moves in the direction of separating, and the cutter blade 29 is moved to the winding paper body P ′.
5 mm away from the end surface of the end plate, and in this state, the end plate Pa is continuously cut by the cutter blade 29. As a result, an ear is formed at the end of the one-pitch Pb (see FIG. 15). When the web P rotates about one revolution, the traveling base 20
Is moved to the side of the paper roll P by a slight amount, and the cutter blade 29 is brought closer to the end face side of the paper roll body P ′ by about 5 mm so that the cut end being cut matches the first cut end. When the outer peripheral edge of the end plate Pa is cut by the cutter blade 29 over the entire circumference, the rotation of the support roller 7 and the reciprocating motion of the cutter blade 29 are stopped, and the cutter bases 28a, 28b, 28c are returned to the return fluid. It is returned to the fixed position by the pressure cylinder 44 and the stopper 45. In addition, an end plate processing mechanism 17 described later
After the clamp 48 holds the cut end plate Pb, the traveling base 20 moves in the direction away from the web P, and the whole end plate cutter mechanism 16 returns to its original position. The web P is stopped at a position where the ears formed at the end of the one-pitch Pb face a cutter blade 78 of a one-punch cutter mechanism 59 described later. In this way, the outer peripheral edge portion of the end plate Pa is cut along the entire circumference by the end plate cutter mechanism 16.

In the above embodiment, the cutter blade 2
9 is used to cut the end plate Pa, but when the end plate Pa of the paper roll P that is doubly packed by the cardboard inside and the vinyl sheet outside is cut, the end plate Pa is cut by the side cutter blade 42. The outer peripheral edge may be cut. That is, when the end plate cutter mechanism 16 moves to the web P side and stops at a predetermined position by the positioning roller 46, the fluid pressure cylinder 43 causes the side surface cutter blade 42 to abut against the outer peripheral edge portion of the end plate Pa. Then, the paper roll P is rotated by the paper roll support device 1. As a result, the end plate P
The outer peripheral edge portion of a is cut along the entire circumference by the side cutter blade 42. Since the end plate Pa of the web P is a thick vinyl sheet, the side cutter blade 4 is used.
The end plate Pa can be smoothly cut without swinging 2.

On the other hand, the end plate processing mechanisms 17 are arranged at the outer positions of both end surfaces of the paper roll P supported by the paper roll support device 1, respectively, and as shown in FIGS.
Fixed clamp plate 48a and movable clamp plate 48, which are provided at the tip of 0 and hold the lower end of the cut end plate Pa.

A fluid pressure cylinder 52, an air jet nozzle 53 provided at the tip of the clamp 48, blowing air toward the lower end of the cut end plate Pa to turn up the lower end of the end plate Pa, and outside both end surfaces of the web P. A plurality of discharge rollers 54, which are rotatably provided at the respective positions, receive the end plate Pa from the clamp 48, hold the end plate Pa, and discharge the end plate; and a motor 55 and a belt transmission mechanism 56 that rotate and drive the discharge roller 54. It is configured.
The discharge roller 54 is composed of an upper roller 54a rotatably arranged at the outer positions of both end surfaces of the paper P, and a lower roller 54b vertically movably arranged below the upper roller 54a. The lower roller 54b is moved up and down by a fluid pressure cylinder 57 so as to come into contact with the upper roller 54a, and is rotationally driven by a motor 55 and a belt transmission mechanism 56.

The end plate processing mechanism 17 is driven and controlled as follows to eject the cut end plate Pa. The clamp 48 of the end plate processing mechanism 17 is
At the time of cutting the end plate Pa, it moves to the end face side of the web P together with the traveling base 20, and the tip end thereof is located near the lower end of the end plate Pa (see FIG. 18). At this time, the clamp 48 is open in the tilted position. Further, the lower roller 54b descends downward. When the end plate Pa is completely cut by the end plate cutter mechanism 16, air is blown from the air ejection nozzle 53 toward the lower end of the end plate Pa, and the lower end of the end plate Pa is turned up (see the alternate long and short dash line in FIG. 18). When the lower end of the end plate Pa is flipped up, the movable clamp plate 48b is swung in the closing direction by the fluid pressure cylinder 52, and the lower end of the end plate Pa is fixed.
It is held between a and the movable clamp plate 48b. Clamp 48
When the user holds the end plate Pa, the traveling platform 20 moves in this state in the direction away from the end face of the paper roll P to separate the end plate Pa from the end face of the web main body P ′ (see FIG. 19), and then the clamp 48 causes the fluid pressure cylinder to move. It is swung from the tilted position to the standing position by 49 or the like, and a part of the end plate Pa is interposed between the upper roller 54a and the lower roller 54b (FIG. 2).
