[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape winding machine for binding paper rolls, and more specifically, a tape on a paper roll capable of winding tapes such as PP tape, craft tape and adhesive tape. Regarding winding machine.

[0002]

2. Description of the Related Art Generally, paper manufactured in a paper manufacturing factory is wound into a roll and shipped as a paper roll. Paper rolls such as newsprint paper and processed paper are wrapped in wrapping paper to maintain the roll state and prevent surface contamination and damage, but cardboard such as paperboard and corrugated cardboard is rolled into paper rolls. A metal band or tape is wrapped directly around the unity. That is, the paper made and dried is wound up on a take-up roll, the edges of the outer circumference are temporarily fixed with adhesive tape, then both ends are cut to a specified paper width, and a metal band or resin / paper tape is wrapped. There is.

The winding of a metal band around a paper roll is conventionally performed as follows. That is, the conventional metal band winding device, the conveyor for transporting the paper roll is connected in series, the band holding ring in the gap between the conveyor and the conveyor is erected in the direction orthogonal to the conveyor, further A connecting mechanism for connecting both ends of the band is provided on a side surface of the band holding ring. Then, when the metal band is wound around the paper roll, the metal band formed slightly larger than the circumferential size of the paper roll is held by the band holding ring in advance, and the band is held in the band holding ring holding the band. Bring in the paper roll and stop at the winding position of the band, then
The outer peripheral surface of the metal band is pressed by a pressing member provided on the band holding ring so as to be pressure-bonded to the paper roll, and both ends are overlapped and connected and fixed by a connecting mechanism.

On the other hand, the winding of the resin / paper tape is performed manually. That is, the end of the tape is pasted on the paper roll placed on the floor, the tape is rolled with both hands while rolling the paper roll, and when the tapes overlap, the tapes are quickly cut and pasted. is there.

[0005]

The conventional method as described above has the following problems. That is, in the case of a conventional metal band winding device, the band must be cut beforehand according to the size of the circumference of the paper roll, and the cut band is used as the band holding ring each time. Since it had to be set, it took time and effort for the preparation work, and it was dangerous. Further, at least both ends of the paper roll need to be bound, but since the conventional metal band winding device is provided with only one band holding ring, after winding one side, move the paper roll. I had to wind the other. For this,
It took a long time to wind the metal band.

Further, when the paper roll is used, the wound metal band must be cut and removed by a cutter. However, when cutting with the cutter, the metal band must be held down while being cut. There was a risk of injury. The metal band cut and removed from the paper roll is generated in a large amount but cannot be reused, so it must be treated as industrial waste, and there is a problem that the storage place and the treatment are expensive.

In the case of manual winding, a resin / paper tape can be used, but since the end of the tape is attached and the tape is rolled using the rolling of a paper roll, workability is reduced. Not only was it bad, but it was difficult to wind the tape along the edges without causing the tape to meander and to overlap the ends. Further, since the tape must be cut while the paper roll is rolling, it needs to be performed by two workers, resulting in high cost.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a tape winding machine for a paper roll which can use a resin / paper tape and can automatically wind both ends at the same time. To do.

[0009]

In order to achieve the above object, this invention has the following configuration. That is, a table plate attached to a pedestal, a paper roll rotating device using one of a pair of rolls provided between the table plates as a drive roll and the other as a kicking roll that can be raised and lowered, and the paper. It comprises a paper roll detection device provided on the side surface of the roll rotation device, and a tape sticking device in which a pair of tape attachment mechanisms are slidably suspended on a vertically movable elevating frame. The tape sticking device is disposed above the paper roll rotating device, and the tape mounting mechanism has at least a tape reel main body to which the tape is mounted, a tape sticking roller that can move up and down to stick the fed tape, and a tape. A tape cutter for cutting the paper, a detection mechanism for detecting the diameter and width of the paper roll, and an air pipe having a large number of small holes formed in the axial direction. It is preferable that the tape attachment mechanism is horizontally moved by a ball nut screwed to a pair of ball screws axially attached to the elevating frame, and encoders are attached to the outer ends of the ball screws. Further, it is preferable that the paper roll rotating device is provided with a stop roll that can be moved up and down between a driving roll and a kicking roll, and further that the tape attaching mechanism is provided with a tape pressing roller for pressing the wound tape. .

[0010]

Since one of the paper roll rotating devices is a driving roll and the other is a kicking roll that can be raised and lowered,
When the paper roll is placed, the drive roll rotates the paper roll, and after the tape winding is completed, the kick roll is raised to eject the roll. Further, since the tape attaching mechanism is hung down on the elevating frame so as to be horizontally movable, it is possible to correspond to the diameter height of the paper roll by elevating the elevating frame and to correspond to the width dimension by the horizontal movement. . Further, the tape can be reliably adhered to the predetermined position of the paper roll blown in the direction of the tape application roller by the air pipe. Further, since the tape applying roller can be raised and lowered, it can be reliably cut without damaging the paper roll by raising it when the tape cutter operates.

[0011]

And a carry-out plate 11 for carrying out the paper roll around which the tape is wound. The carry-in plate 10 and the carry-out plate 11 are inclined in the same direction and are attached to the gantry 1 at regular intervals, and the inclination is formed so that the paper roll rolls in the carry-out direction. Therefore, the paper roll is rolled using the inclination of the carry-in plate 10 and carried into the paper roll rotating device 5, and is similarly carried out utilizing the tilt of the carry-out plate 11. The paper roll rotating device 5 is arranged between the carry-in plate 10 and the carry-out plate 11. Figure 3 shows a flat surface view of the table plate 3 and the paper roll rotating device 5 shown by cutting a central portion of the table plate 3, 4 is positive elevational view of a roll rotating device 5, the same operating state FIG 5 described It is a side view for use.

The paper roll rotating device 5 is provided with auxiliary rolls 15 on both sides of a drive roll 13 for rotating the paper roll, and a kicking roll 19 is mounted on a support rod 17 rotatably attached to the rotary shaft of the drive roll 13. The auxiliary rolls 20 are provided on both sides of the kicking roll 19. Further, the drive roll 13 and the kicking roll 1
Between 9 and 9, a stop roll 21 that temporarily receives the rolling of the paper roll is provided so as to be able to move up and down. The drive roll 13 is axially mounted on a bearing provided on the frame of the gantry 1, and is provided between a sprocket 23 fixed to the rotation shaft of the drive roll 13 and a sprocket 27 of a geared motor 25 with a brake installed below. The chain 29 is wound. The auxiliary roll 15 is axially attached to the frame of the gantry 1 on the same axis as the drive roll 13, and when the width of the paper roll is larger than that of the drive roll 13, the paper roll is placed and rotated.

The support rod 17 on which the kicking roll 19 is axially attached is formed in a substantially U-shape in a plane, and the tip ends thereof are rotatably attached to both sides of the drive roll 13 by bearings to form a central portion. The rod 31 of the air cylinder 30 is connected to the lower surface. Therefore, when the air cylinder 30 is driven, the connecting rod 17 rotates about the rotation axis of the drive roll 13, and the kicking roll 19 is lifted upward. In this manner, the kick roll 19 is lifted to push out the paper roll and eject it from the paper roll rotating device 5. The auxiliary roll 20 is axially attached to the frame of the pedestal 1 on the same axis as the kick roll 19, and when the width of the paper roll is larger than that of the kick roll 19, the paper roll is mounted on the frame. It is placed and rotated.
In the above embodiment, the support rod 17 having the kicking roll 19 attached thereto is attached to the rotary shaft of the drive roll 13.
It is of course possible to rotatably attach to another shaft.

As is clear from the above description, the paper rolls mounted on the drive roll 13, the auxiliary roll 15, the kicking roll 19 and the auxiliary roll 20 are driven by the geared motor 25 to rotate the drive roll 13.
It will rotate in the opposite direction to the drive roll 13. Further, a stop roll 21 is provided between the drive roll 13 and the kick-out roll 19 to stop the rolling of the paper roll during loading. That is, the stopping roll 2
1 is rotatably attached to the tip of a U-shaped arm 35 which is rotatably attached to a shaft 33 fixed to the frame of the gantry 1. The arm 35 is formed in a substantially U shape so as to avoid contact with the kicking roll 19 when it rises, and is provided below the kicking roll 19.

Further, a rod 39 of an air cylinder 37 is fixed to the arm 35. Therefore, when the arm 35 rotates about the shaft 33 by the driving of the air cylinder 37 , the stop roll 21 is lifted upward and protruded from the drive roll 13 and the kick roll 19. When the stopping roll 21 projects, the rolling paper roll is temporarily stopped. At this time,
Since the stopping roll 21 is rotatably attached, the rolling of the paper roll is absorbed together with the kicking roll 19 and the paper roll can be prevented from jumping over the stopping roll 21 by inertia.
Although the stopping roll 21 is attached to the rotatable arm 35, the stopping roll 21 may be simply moved up and down in the vertical direction.

Next, the paper roll detecting device 7 provided on the gantry 1 on both sides of the paper roll rotating device 5 will be described. As shown in FIGS. 1 and 3, the paper roll detection device 7 includes a photoelectric tube 40 provided on the side of the kick roll 19 for confirming the existence of the paper roll, and a paper roll provided on the side of the stop roll 21 for driving the paper roll 13.

03 is slidably inserted into the through hole of the base 110 fixed between the upper and lower ends of the base 03, and the upper end of the support arm 109 is supported by a retaining ring. Further, a coil spring 111 for urging the tape pressing roller 105 downward is mounted on the support arm 109 between the roller shaft 107 and the base 110. Therefore, when the tape pressing roller 105 is pressed against the paper roll and pushed up, the support arm 109 slides in the through hole of the base 110, but the coil spring 111 works downward by the biasing force.

Further, a tape reel main body 113 with a reverse rotation prevention is attached to the hanger frame 99, and the bracket 1 is provided on the upper surface of the central portion of the side plate 100.
15 are erected. A guide roller 117 for guiding the tape and a photoelectric tube 119 for detecting a cutout portion of the guide roller 117 are attached to an upper portion of the bracket 115. The photoelectric tube 119 detects the tape break by detecting the rotation state of the guide roller 117. Further, an air cylinder 120 is suspended from the bracket 115, and a rod 121 of the air cylinder 120 is fixed to a roller bracket 127 having a roller shaft 125 of a tape applying roller 123 attached thereto.

As shown in FIGS. 9 and 13 , the roller shaft 125 has a link arm 129 rotatably attached to a shaft 128 having the other end fixed between the side plates 100 and 103.
And an arm 130 is provided inside the link arm 129. The arm 130

They are connected by 31. The guide roller 13 3 to the lower end of the arm 130 which is knurled
And the reverse rotation prevention roller 135 is axially attached. Therefore,
At the same time as the tape applying roller 123 moves up and down by the driving of the air cylinder 120, the link arm 129 rotates about the shaft 128, so the guide roller 133 and the reverse rotation preventing roller 1 attached to the arm 130 are rotated.
35 also goes up and down integrally.

A tape cutter 137 is arranged between the side plates 100 and 103. That is, the rear end of the air cylinder 139 is rotatably attached to the hanger frame 99 to which the tape reel body 113 is attached, and the rod 140 of the air cylinder 139 is attached to the shaft 142 fixed between the side plates 100 and 103. It is connected to the end of a cutter arm 141 rotatably attached to the shaft. At the end of the cutter arm 141, a cutter retainer 14
The tape cutter 137 is detachably attached via the connector 3. Therefore, when the rod 140 moves back and forth by driving the air cylinder 139, the cutter arm 1
Since 41 rotates about the shaft 142, the tape cutter 137 can be retracted between the tape applying roller 123 and the tape pressing roller 105.

Further, a photoelectric switch 147 is attached to the outer surface of the bracket 115 provided upright on the side plate 100 as a device for detecting the end of the paper roll. When the slide plate 80 moves horizontally and the end of the paper roll is detected by the photoelectric switch 147, the slide plate 80 stops moving horizontally. When the horizontal movement of the slide plate 80 is stopped, the paper roll is rotated by the drive roll 13 and the tape application roller 1
The winding of the tape by 23 is started.

Between the pair of tape mounting mechanisms 47,
As shown in FIG. 7, the paper roll height detection mechanism 14
9 are provided. That is, a hanger plate 153 having a cylindrical body 151 erected on the lower end of a hanger bracket 150 hanging from the lower surface of a central frame 83 that axially supports the ball screw 87 is installed, and the lower end portion of the hanger plate 153 has the hanger plate 153 inside. A shaft 155 penetrating and projecting downward is hung, and a proximity switch and a limit switch that are activated when the shaft 155 rises are provided. When the proximity switch is activated, the lowering of the lifting frame 45 is stopped and the ball screw 87 is driven.
Then, the tape attachment mechanism 47 is moved horizontally. The limit switch lowers the elevating frame 45 again for winding the tape, and stops the lowering of the elevating frame 45 when the tape applying roller 123 and the tape pressing roller 105 come into contact with the paper roll.

Next, a method of using the tape winding machine having the above structure will be described. First, the tape to be wound is attached to the tape reel body 113, the drawn tape is hung on the upper surface of the counter roller 117, then wound around the guide roller 134 and placed on the reverse rotation prevention roller 135 from the lower side of the guide roller 133, and the leading end portion thereof. Is hung and placed by such a length that the tape can be attached by the tape application roller 123. Next, the elevating frame 45 is raised, the tape attachment mechanism 47 is moved closer to the central frame 83 side to stand by, and the tape applying roller 123 is moved to the air cylinder 12.
Activate 0 and pull up. Further, in the roll rotating mechanism 5, the air cylinder 37 is operated to pull up the stopping roll 21.

Next, when the paper roll is placed on the carry-in plate 10 and rolled, it abuts against the stopping roll 21 and stops. At this time, the rotational force of the paper roll is absorbed by the stopping roll 21 so that the paper roll can be stopped without jumping over. When it is confirmed by the photoelectric tube 40 that the paper roll is stopped and is present on the kick roll 19, the air cylinder 37 is activated again to pull down the stop roll 21. Next, when it is confirmed by the photoelectric tube 41 that the paper roll is placed on the drive roll 13 by pulling down the stop roll 21, the geared motor 57 is activated to lower the elevating frame 45. When the height position of the paper roll is detected by the height detection mechanism 149 that the elevating frame 45 descends and hangs down on the central frame 83, the elevating frame 45 stops descending.

When the lowering of the elevating frame 45 is stopped, the motor 93 of the tape mounting mechanism 47 is operated to drive the ball screw 87 via the chain 97. The slide plate 80 horizontally moves outward by driving the ball screw 87, and the photoelectric switch 147 mounted on the bracket 115 is moved.
Detects the end of the paper roll and stops driving the motor 93. Next, when the geared motor 57 is actuated again to lower the elevating frame 45, the height detection mechanism 14
Since the shaft 155 of 9 is pushed up, the geared motor 57 is stopped by the limit switch. This completes the preparation for tape winding.

Then, the geared motor 25 is operated to rotate the drive roll 15 to rotate the paper roll. At the same time, the air cylinder 120 is operated to pull down the tape application roller 123 and press it against the paper roll. At this time, the tape is made to flutter toward the tape pressing roller 105 side by the air ejected from the small holes of the air pipe 145. When the end portion is attached to the paper roll and pressed by the tape application roller 123, the tape can be automatically wound because the paper roll itself is rotating.

When the paper roll makes one revolution, the air cylinder 120 is activated to operate the tape application roller 12
At the same time when 3 is pulled up, the air cylinder 139 is operated to push down the tape cutter 137 to cut the tape. The tape application roller 123 when cutting the tape
Since a slight gap is provided between the tape and the paper roll by pulling up, the tape cutter 137 can cut only the tape without damaging the paper roll. At the same time as cutting the tape, the rotation of the paper roll by the drive roll 13 is stopped.
After that, the air cylinder 30 is operated to pull up the kicking roll 19 to push out the paper roll. The extruded paper roll is unrolled by rolling on the inclined unloading plate 11.

The motor, air cylinder and the like as the drive mechanism in the above embodiment may be changed to other known drive mechanisms. In addition, the auxiliary roll 1 of the roll rotating device 5
5 and the auxiliary roll 20 can be omitted. Further, in the embodiment, the table plate 3 is tilted to be carried in by rolling the paper roll, but the table plate 3 may be horizontally mounted and the paper roll may be carried in by other means. When the table plate 3 is mounted horizontally, the stopping roll 21 can be omitted.

As is clear from the above description, the following effects can be obtained in the above embodiment. That is, the tape sticking device 9 is composed of a pair of tape mounting mechanisms 47 provided so as to be vertically movable and horizontally movable.
Since a device for measuring the diameter (height) and width dimension of the paper roll is attached to, the diameter and width dimension of the paper roll are automatically identified and the tape winding length is automatically determined. Therefore, it is possible to prevent excessive consumption of the tape and improve the working efficiency. Further, by automatically measuring the width dimension of the paper roll, both ends can be wound at the same time, and it is also possible to wind three rolls or four rolls. Further, since both end positions are automatically measured together with the width dimension, it is not necessary to perform centering each time the paper roll is loaded, and all the loading and unloading can be performed automatically.

Since it is possible to use PP tape, kraft tape, etc., the product is not damaged as compared with the conventional metal band, and the cost can be greatly reduced. Further, since the tape only needs to be attached to the reel unit, the tape replacement work and cutting work can be performed safely and easily. Furthermore, the working environment can be improved without the problems of storage space and disposal such as metal bands.

[0037]

As described above, according to the present invention, the resin tape and the paper tape can be used, and the tape can be automatically and simultaneously wound at both ends, so that the tape winding can be performed efficiently and safely. It can be carried out. Further, not only can the cost be greatly reduced as compared with the metal band, but the problem of storage and disposal of the band removed by cutting can be solved.
