Description

DETAILED DESCRIPTION OF THE INVENTION The basic configuration of a web winding device conventionally used in paper mills etc. is shown in FIG. 1, and FIG.
It also shows the state of the winding operation in which the next winding is started after the steps shown in FIGS. 4 and 5 have been completed.

In FIG. 1, the web 2 is rewound from the rewound roll 1.
is vertically cut into a predetermined width by a slitter 3 and placed in a winder drum 4.
is guided between the take-up roll 5 and the rider wheel 6 and wound up.

The winding roll 5, which has been completely wound, is pushed out by a dump roll 7, passes through a winder table 8, and is lowered onto a cradle 9. Reference numeral 10 designates a core shaft with a core attached, which is stored in a shaft pocket.

Here, the conventional winding method will be explained with reference to FIGS. 1 to 7. The web 2 from the unwinding roll 1 is vertically cut into a predetermined width by a slitter 3, and the web 2 is cut into a predetermined width by a predetermined take-up roll 5 on a winder drum 4. When completed, the rotation of each roll is stopped in the state shown in FIG.

FIG. 2 shows a state in which, after lifting the rider roll 6 vertically upward, the operator climbs onto the winder table 8 and tears the outer layer of the take-up roll 5 in the width direction.

FIG. 3 shows a state in which the dump roll 7 is rotated around the four axes of the wine drum on the right side and the take-up roll 5 is pushed onto the cradle 9.

Thereafter, the dump roll 7 retreats to its original position, and the core shaft 10, which had been previously stored in the shaft pocket, is transferred to the V-groove formed by the two winder drums 4 using a conventionally known shaft bringing device (not shown). ) brought in by 1.

Next, FIG. 4 shows the core chuck (
The operator 12 carries out the work of holding the web 2 by the web 2 (not shown) and lifting it in the vertical direction, and then equalizing the tension of the web 2 in the width direction between the unwinding roll 1, the roll 11, and the core shaft 10. This indicates the state of being.

Thereafter, another operator lowers the core shaft 10 onto the winder drums 4, 4 again, and when the tip of the web 2 is bonded to the core shaft 10 with adhesive tape 13, the excess web is removed manually by the operator in the width direction. and is removed from the winder 4.

FIG. 5 shows a state in which the leading end of the web 2 is adhered to the core shaft 10 by the adhesive tape 13 as shown in FIG. 6 by the operator 12's direct manual operation.

Figure 7 shows the operator leaving the top of the winder drum 4.
The rider roll 6 is in a state where it is pressurized downward onto the core shaft 10, and after this, each roll of the winder starts rotating again by a drive motor (not shown), and a web 2 is formed on the outer periphery of the core.
are rolled up to form the state shown in Figure 1.

However, in the conventional web winding device described above,
Immediately before the state shown in FIG. 2, an operator had to climb onto the winder and manually tear the outer layer of the take-up roll 5 directly in the width direction.

Next, at the beginning of winding, the operator climbs onto the winder again and
The work to equalize the tension distribution of the web 2 from the unwinding roll 1 to the core shaft 10 had to be carried out directly by hand.

Moreover, this operation requires skill, and in the event that the tension distribution is not uniform, it is necessary to proceed to the 11th step and start winding...At the beginning of the main winding, the web is easily cut, which is critical for winding. There were some drawbacks that were a hindrance.

Further, as shown in FIG. 5, the operator had to directly and manually adhesively fix the leading end of the web to the core shaft using adhesive tape on the winder.

Although the above-mentioned direct manual work by the operator is required due to the lack of equipment and functions of the winder, it is completely preferable from the viewpoints of labor, safety, and work capacity. It wasn't.

The present invention has been proposed in order to solve the above-mentioned drawbacks of the conventional winder, and it does not require major changes to the work procedures normally carried out in conventional winders, nor does it require major changes to the mechanical structure of the winder. , by simply adding some equipment, we can mechanize all the manual manual work done by traditional operators,
It is an object of the present invention to provide a web winding device that is safe and can improve work efficiency.

Embodiments of the present invention will be described below with reference to the drawings.

In other words, the winder showing the embodiment of the present invention shown in Figs. 8 to 11 is equipped with each device shown in Figs. 12 to 19. Since this would complicate the drawings, the same device is not shown in FIGS. 8 to 11.

Now, FIG. 8 shows a state in which the take-up roll 15 has been wound onto the winder drum 14, 14', and then the rider roll 16 is lifted vertically upward by the operation of a switch by an operator located on a control desk (not shown). The unwinding roll 17 independently rotates at a low speed to feed out the web 18, and the roll stopper 19 further rises.

FIG. 9 shows the state after this operation.

The operation of the rider roll 16, the low-speed rotation of the rewind roll 17, and the operation of the slitter 20 are performed by conventional, well-known methods, and are not directly related to the present invention, so a detailed explanation will be omitted.

FIG. 10 shows that the take-up roll 15 is pushed onto the winder table 22 by the dump roll 21, and the roll stopper 19
When the take-up roll 15 comes into contact with the roll 23, the roll stopper 19 automatically retreats at a low speed, and in the process, tension is again generated in the web 18 previously unwound from the unwind roll 17.

Further, the dump roll 21 is also conventionally known and is not directly related to the present invention, so a detailed description thereof will be omitted.

The roll stopper 19 is a part of the gist of the present invention, and will be described in detail below. FIG. 12 is a plan view of the roll stopper 19, and FIG. 13 is a front view of the same, both of which show parts unrelated to the main parts. is omitted.

In the figure, a foundation 25 is raised on the building floor 24, and a hydraulically operated swing motor 26 for operating the roll stopper 19 is fixed to the foundation with foundation bolts.

As this swing motor 26, a conventionally known swing motor is used.

Further, the output shaft of the swing motor 26 is connected to a shaft 29 supported by a bearing 28 via a coupling 27 so as to be capable of transmitting torque.

An arm 30 is fixed to the shaft 29 via a key, and a bearing 31 is fixed to the tip of the arm 30 with a screw or the like, and the bearing 31 rotatably supports the roll 23. .

When the hydraulic pressure generated by a hydraulic unit (not shown) passes through an appropriate control device and acts on the hydraulically operated swing motor 26, the roll 23 rotates around the shaft 29, and the roll 23 has a winding section. The power to receive the roll 15 is obtained.

Now, when the roll stopper 19 is installed on the winder table 22 and the roll 23 is swung up on the table 22, the winding roll 1 pushed out by the dump roll 21
5 is in contact with the roll 23, and the same roll 15 is in contact with the cradle 3.
By reducing the operating speed when being rolled out toward the winder table 22, the take-up roll 15 can be quietly stopped on the winder table 22 so that the web 18 does not break during the rolling out process.

Further, the upper surface of the winder table 22 has a slope necessary for the winding roll 15 to roll toward the cradle 32 without receiving external force, but the web 18 of the winding roll 15 is connected by the unwinding roll 171. If so, the web 18 has a suitably limited slope to prevent breakage of the web 18.

FIG. 11 shows a state where the winding roll 15 is stopped on the winder table 22 and the web 18 is connected from the winding roll 15 to the unwinding roll 17, but the state shown in the drawing is the winder drum 14.14. In FIG. 10, the core shaft 33 that was in the shaft pocket is brought into the groove (pocket) formed by ', and the rider roll 16 is moved into the web 1.
8 and descends onto the core shaft 33 to apply pressure.

In addition, in the process of transitioning from the state shown in FIG. 10 to FIG. It is moved to the position shown in FIG. 11 by a shaft bringing-in device which will be described later.

Next, the tape pasting device will be explained with reference to FIGS. 14 to 17. FIG. 14 is an enlarged sectional view of the shaft pocket while the tape is pasted, and FIG. 15 shows the adhesive tape 34 pasted on the outer surface of the core shaft 33. It is the same sectional view after completion of attachment.

In the figure, reference numeral 35 denotes a cylindrical shaft having a length sufficient to perform the tape sticking function in the width direction of the winder, and is attached to the winder table 22 by a threaded rod 36.

37 is a linear motion bearing into which the cylindrical shaft 35 is inserted, and S6゜38 is a frame which incorporates the linear motion bearing 37, is movable smoothly in the direction of the cylindrical shaft 35, and is movable in the circumferential direction of the cylindrical shaft 350. A slight swing is also possible.

Further, the frame 38 can be easily moved in the direction of the cylindrical shaft 35 by rotating a chain wheel 40 provided in the loop of a roller chain 39 connected to the frame 38 using a reduction AC motor with a flake (not shown). will be visited.

The rotation of the AC motor is easily performed by the operator operating a switch in an electric circuit (not shown), and the movement of the frame 38 is detected at a limited position using a microswitch, etc., and the rotation of the motor is controlled by the signal. It is also possible to start or stop it.

The swing motion of the frame 38 around the cylindrical shaft 35 is performed by pushing a cam follower 41 attached to the lower part of the frame 38 with a rail 42 (FIG. 15).

The rail 42 is provided parallel to the cylindrical shaft 35 over the entire thickness of the winder, and can be slid horizontally.The sliding movement is achieved by connecting the air cylinder or oil cylinder rod and the rail 42 with a connecting fitting. This can easily be done by applying pressurized air or oil pressure to the cylinder.

A tape support shaft 43 is attached to the frame 38, and a double-sided adhesive tape 34 wound in a cylindrical shape is attached to the same shaft 43.
' is rotatably fitted.

Here, in the first stage of the tape pasting work, the frame 38 is further removed from the operating measuring end of the core shaft 33 by the winder operation shout.
is placed on standby at the outside of the winder, and in this state the tape 3 is removed from the adhesive tape 34' wound in a cylindrical shape.
4 is manually fed out and passed through the outer periphery of rollers 44 and 45 along the path shown in FIG. It passes through the nip between rollers 46 and 47 and is guided to a basket 48.

The roller 46 is pressed against the roller 47 by the coil spring 49, but by lifting the lever 50, a gap necessary for passing the separator can be obtained.

Further, there are no obstacles under the rollers 45 and 46 at this stage because the work is performed at a position away from the core shaft 33 in the axial direction as described above.

Next, in the second step of the tape application operation, the sprocket 40 is rotated by a motor, the frame 38 is guided onto the core shaft 33 to the state shown in FIG. 14, and is further moved toward the first drive end of the winder.

This movement causes the adhesive tape 34' to move away from the tape 3.
4 is continuously pulled out, leaving an adhesive layer of adhesive tape 34 on the outer surface of core shaft 33.

In this case, the tape separator is continuously separated from the adhesive layer and collected in a basket 48 as shown in FIG.

The guide plate 51 is for making it easier for the separator to enter the basket 48.

Next, the operation of the third stage of the tape pasting work will be explained with reference to FIG. It collides with the tape cutting unit 54 pushed out to the appropriate i position of the terminal end.

FIG. 17 shows the state immediately before this collision.

Further, the one-dot chain line shown in FIG. 17 indicates that the tape sticking unit 52 further retreats the tape cutting unit 54 after the collision.

Also, a tape pasting unit 52 and a tape cutting unit 54
At the moment of the collision, a bumper 55 provided on the tape cutting unit 54 presses the tape 34 against the roller 44, and a sawtooth cutter blade 56 bites into the tape 34 and cuts the tape.

Further, the movement of the tape sticking unit 52 after the tape 34 is cut due to the collision as described above is caused by the movement of the tape sticking unit 52.
This is necessary in order to completely adhere the tape 34 left inside onto the core shaft 33.

Also, in the fourth stage of the tape application work, the tape application unit 5
2 rises away from the core shaft 33 as shown in FIG. 15, and returns to the standby position of the operating end again by the reverse rotation of the sprocket wheel 40.

At this stage, the tape cutting unit 54 is almost retracted to the 1 drive end, and the new core shaft 33
After the air cylinder 53 is brought into the shaft pocket part
The tape is extruded at the tape cutting position 1.

The air cylinder 53 immediately retreats after pushing out the tape cutting unit 54.

Next, the core shaft bringing-in device will be explained with reference to FIG. 18. FIG. 18 shows the core shaft 33 on which the double-sided adhesive tape 34 has been adhered to the upper surface by the tape pasting device.
1 shows a conveyor shaft conveying device using a known conveyor chain with an attachment, and an arm-type shaft bringing device that rotates around the winder drum 14 axis. 583 chain sprockets are rotatably assembled in the 1st state. 01 of the sprockets 58 has a sprocket shaft 59 protruding outside the frame, and a driving roller chain sprocket 60 is attached to the shaft end. is attached with a key 61 so that torque can be transmitted.

A conveyor chain 62 is hung on the sprocket 58, and one link of this chain is equipped with an attachment.

A shaft holder 63 is fixed to this attachment.

When the rotation of the mold motive is transmitted to the 1-driving roller chain sprocket 60 by a chino, the core shaft 33 is scooped up by the shaft receiver 63 and conveyed by the top 1 of the winder drum 14.

During this conveyance process, the conveyor chain 62 is routed so that the core shaft 33 does not come into contact with anything other than the shaft support 63 supporting the operating part 11 and the ends of the first drive shaft.

Therefore, the core shaft 33 does not roll many times during transportation.

The core shaft 33 is passed to a pivoting shaft-feeding arm 64 at the top of the winder drum 14 and then
rotates and the winder drum 14 and the winder drum 14'
The core shaft 33 is carried into the groove (pocket) formed by the winder drum 3, but even during this operation process, the core shaft 33 is
3, the core shaft 33 hardly rotates.

The adhesive tape 34 can therefore be introduced between the drums 14, 14' without coming into contact with the web 18.

In other words, the rotating shaft carry-in arm 64 has a conventionally known structure, but the shape of the tip of the arm has been devised so that the core shaft 33 does not come into contact with the drum during the carry-in process. There is.

Further, the shaft receiver 63 is returned to the standby position shown in FIG. 18 by reversing the chain sprocket shaft 59.

The steps leading to FIG. 11 have been described above, and next, the web cutting operation in the next step performed from the state shown in FIG. 11 will be described with reference to FIGS. 19 to 22.

When the winder is in the state shown in FIG. 11, the web cutting device 65 is in the state shown in FIG. 19.

Reference numeral 66 is a rider roll beam whose main function is to support the rider roll 16 via a bearing device, which is conventionally known.

The web cutting device 65 changes the web 18 and the web cutting device 6 from the state shown in FIG. 19 to the state shown in FIG.
You can change the relative position of 5.

The winder is started in the state shown in FIG. 20, the winder drums 14, 14', rider roll 16 and core shaft 33 start rotating, and the adhesive tape 34 adhered onto the core shaft 33 reaches just before the cutting device. 21 and 22, the cutting knife 70 shown in FIGS.
It pops out from the slit part of 1 by the solenoid 72,
Web 18 is cut.

After the cutting knife 70 instantaneously performs the cutting operation, it retreats again into the slit portion of the web presser plate 71 by the force of the coil spring 73, and then the air cylinder 68 is activated to prevent the web presser plate 71 from coming into contact with the take-up roll 15. In position 1 the entire web cutting device 65 is lifted.

In this case, the cutting operation and the lowering and raising operations of the entire cutting device are electrically controlled by detecting the rotation angle of the shaft of the winder drum 14 with a pulse transmitter, which is a conventionally known method. Detailed explanation will be omitted.

As explained in detail above, since the present invention is provided with a roll stopper, the operating speed when the take-up roll is rolled out toward the cradle is weakened, and the web is taken up quietly to prevent breakage of the web during the rolling process. The roll can be stopped on the winder table.

In addition, since the present invention is equipped with a device for pasting adhesive tape, it has a very large effect in terms of labor saving in modern winders whose core shaft length usually reaches 3000 to 8500 mm. By using the device, it is possible to safely perform a tape application operation in parallel with the winding operation being carried out on the wine drum at high speed.

Furthermore, when transferring the core shaft of the present invention to the pocket between the winder drums, it is unnecessary for the core shaft to rotate during conveyance as in the case of conventional core shaft conveyance devices, so it is necessary to cut the web. The core shaft can be brought in without having to attach the adhesive tape to the web.

Furthermore, the apparatus for cutting the web of the present invention includes a winder drum,
The shape of the core shaft and rider roll has been designed to be strong and compact so that it can be accommodated in the limited space available as the conventional standard size 11, and the cutting operation can be performed by direct solenoid operation, so the response is quick. , the purpose of cutting can be achieved without interrupting operation immediately after the winder is started.

Therefore, according to the present invention, conventional manual work can be mechanized to significantly save labor, work becomes safer, and work efficiency can be greatly improved.

Hiko, this invention can be applied to paper winding machines.
