DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a web paper manufacturing facility disposed in a paper mill, and more particularly to a paper splicing preparation apparatus provided as a web paper manufacturing facility.

[0002]

2. Description of the Related Art FIG. 20 is a diagram showing a typical layout of rolled paper manufacturing equipment installed in a paper mill. As shown in FIG. The apparatus 1 is arranged to take up paper continuously produced in a paper machine on a core called a reel spool 9 to produce a large-diameter wide-width web.

A large-diameter wide-width paper roll made by the reel part 1 is called a main roll 6, and the size of the main roll 6 is, for example, a large one having a diameter of 3200 mm, a width of 8300 mm, and a weight of 58 tons. is there. A paper winder 2 called a winder is provided adjacent to the reel part 1. The winder 2 has a winding paper of a size required by a printing company from a parent winding 6 (hereinafter, referred to as a shipping roll).
101 is manufactured.

The winder 2 is provided with a device 3 called an unwinder, which is one of the winder constituting devices. The unwinder 3 receives a master winding 6, and unwinds paper from the master winding 6 on the unwinder 3 for shipping. The roll 101 is manufactured. There is almost no use of the master winding 6 made of the reel part 1 as it is in the unwinder 3, and usually at least the following work is performed on the master winding 6 between the reel part 1 and the unwinder 3. It is done.

[0005] An operation for removing loose paper having wrinkles on the outer layer portion of the parent roll 6 generated at the time of frame change in the reel part is performed. This operation is performed by the operator directly near the exit of the reel part 1 as shown in part A of FIG. The work of transporting the defective paper (broke) removed from the master roll 6 to a dissolving device called pulper 7 is performed.
This operation is also performed as shown in part A of FIG.
This is done by the operator directly near the exit.
Since the pulp 7 is normally arranged below the reel part 1, the operator carries the broke on the floor of the reel part 1 and drops the broke into the pulp 7 from the input port.

[0006] The master winding 6 after such an operation is performed.
Is transported to the unwinder 3, and the leading end of the paper of the rear parent roll 6 is sent into various devices constituting the winder 2,
Core (winding core) 10 by winder drum 102
The winding of the shipping roll 101 is started by being adhered to the surface of a small-diameter paper tube referred to as 3. In the conventional paper roll manufacturing equipment arrangement as shown in FIG. 20, the operation from the unwinder 3 to bonding the paper end of the parent roll 6 to the core 103 on the winder drum 102 is usually performed by two or more operators. The working time requires 5 to 6 minutes.

Recently, the papermaking speed of a paper machine has been increased to 1500 m.
/ Min, and the master winding 6 to 1 produced in such a high speed paper machine.
Production efficiency has been demanded such that a single winder operator manufactures a shipping roll 101 for one winder 2. In order to satisfy this demand, the time required by the conventional two or more operators (the time during which the winder stops, usually 5
〜6 minutes) within the winder by one operator within 200 seconds. Tokuhei 2
The -11493 unwinder has been widely applied in the industry to various types of winders as well as super calenders as a means of satisfying a substantial part of this demand.

[0008]

However, in order to use the technique disclosed in Japanese Patent Publication No. 2-11493, an adhesive is previously applied to the surface of the leading end of a new parent roll (new web roll) brought into the unwinder. Must be applied. FIG. 21 is a diagram showing a relatively recent arrangement of the web production equipment. As shown in FIG. 21, the reel part 1 and the unwinder 3 are connected by the down-sloped rail 12, and are formed by the reel part 1. Unwinder 3
A method of automatically transporting to In addition, 1
Reference numeral 00 denotes a spool unloader that unwinds the paper and rewinds the empty reel by the unwinder 3 and carries the reel upward.

As a result, the heavy master winding 6 can be transported safely, reliably, and automatically without using a crane. Therefore, there are already operating examples in the industry, and standardization is expected in the future as labor and labor are reduced. It is expected that this will be adopted. Further, in the arrangement example of FIG.
The technique of No. 11493 is applied in a slightly modified form.
That is, in the case of Japanese Patent Publication No. 2-11493, the master winding 6 made of the reel part 1 is unwound by the crane 3
Since it is possible to apply the adhesive to the surface of the leading end portion of the paper of the master winding 6 before carrying the material into the unwinder 3, in the arrangement example of FIG. Since the master roll 6 is automatically conveyed to the unwinder 3, it is impossible to apply an adhesive beforehand to the surface of the leading end portion of the paper of the master roll 6 before being carried into the unwinder 3.

Therefore, in the arrangement example of FIG. 21, it is possible to apply an adhesive to the surface of the leading end portion of the paper of the master winding 6 somewhere in the middle of the transport path of the master winding 6 from the reel part 1 to the unwinder 3. Will be needed. However, it is obvious from the viewpoint of safety that it is not preferable for the operator to enter the conveying device in which the master winding 6 moves from the upstream and apply the adhesive.

[0011] By the way, as the kind of the adhesive, it is necessary that the adhesive strength is strong and the adhesive strength is maintained for a long time, but in order to satisfy them, it is preferable to use a double-sided adhesive tape. However, it is impossible for a single operator to adhere the double-sided adhesive tape to the large-diameter and wide roll surface having a diameter of 3 m and a width of 8 m as described above in a short time.

In other words, with the equipment arrangement as shown in FIG. 21, the demand for increasing the production efficiency of a paper mill having the above-described high-speed paper machine can be satisfied both in terms of safety and the number of required operators. It can not be said. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and in a parent winding transport system from a reel part to an unwinder, a paper splicing preparation operation required by the unwinder can be automatically performed on the parent winding.

As shown in FIGS. 1 and 2, the paper splicing preparation device includes a parent winding storage stand (support table) 4 two upstream (ie, closer to the reel part) than a stand (unwinder stand) 3A of the unwinder 3. It is arranged near. By selecting such an installation position, the unwinder stand 3 is one
The parent winding 6 ready for splicing can be made to stand by in the parent winding storage stand 5 immediately upstream. It is provided on the second floor of a papermaking room having an unwinder 3 and a reel part.

An important splicing preparation operation in the splicing preparation device is to attach a double-sided adhesive tape 84 as a bonding material to the paper fed from the parent roll 6, and therefore, the splicing preparation device requires a double-sided adhesive tape. A device (bonding material sticking device) 20 for sticking the tape 84 is provided. The bonding material sticking apparatus 20 is installed on the floor (2FL) of the second floor of the papermaking room below the parent roll 6.

Therefore, the knife 29 can be pushed and pulled by extending and contracting the air cylinder 25. Then, if the knife 29 is pushed while the paper W is sandwiched between the web guide beam 21 and the paper holding beam 31, the paper W can be cut. In other words, when the knife 29 is pushed out of the retracted state as shown in FIG. 17B, it can protrude as shown in FIG. 18B and cut the paper W.

After the adhesive layer 84G of the double-sided adhesive tape 84 is transferred to the paper W in this manner, an unnecessary portion of the leading end W1 of the paper W is cut by the knife 29, and thereafter, as shown in FIG. Then, the web guide beam 21 and the paper holding beam 31 are opened, and the master winding 6 is reversed. The state shown in FIG. 19 is a state in which a series of paper splicing preparation steps has been completed, and the position of the adhesive layer 84G is controlled to the 8 o'clock position of the clock.

The master roll 6 prepared for splicing is sent to the winder 2 which is the next step. Since the splicing preparation device according to an embodiment of the present invention is configured as described above, splicing preparation is performed as follows. That is, first, as shown in FIG. 1, while the master winding 6 travels on the rail 12 from the reel part 1 toward the unwinder 3, the master winding storage stand 4
Transported to At this time, in the master winding storage stand 4, the shock when the master winding 6 is transferred is absorbed by the air-operated link mechanism 10 including a hydraulic shock absorber, and the master winding 6 is stopped on the master winding storage stand 4.

At this time, the leading end portion W1 of the paper W being unwound from the main roll 6 usually hangs slightly from the main roll 6 as shown in FIG. When the portion W1 does not hang down slightly from the master roll 6, the position of the leading end portion W1 of the paper W is adjusted by operating the master roll rotating device 8 and rotating the master roll 6.

On the other hand, when the master winding 6 is transferred into the master winding storage stand 4, this is detected by a limit switch (not shown), and the main winding diameter detecting device 11 operates to measure the outer diameter of the master winding 6. PLC whose signal is not shown
Sent to In the PLC, upon receiving the measurement signal, a required operation signal is issued to the motor 48 of the moving mechanism 50 to rotate the motor 48 so that the web guide beam 21 and the paper pressing beam 31 of the bonding material attaching apparatus 2 are moved as shown in FIG. As shown in FIG. 3, the paper W is moved so as to be at the best position with respect to the transferred parent roll 6, that is, a position immediately below the leading end portion W1 of the paper W hanging from the parent roll 6.

Here, as shown in FIG. 5, the master winding 6 is rotated at a low speed through the master winding rotating device 8, and the paper (web) W fed from the master winding 6 is advanced into the broke pulper 7. The leading end W1 of the paper W is
When it reaches the water flow swirling inside, the leading end portion W1 of the paper W is dissolved while being pulled by the water flow. At this stage, parent roll 6
When the feeding speed is controlled so that a tensile tension is generated in the paper W fed from the web, a flat paper W without wrinkles or slack is eventually obtained in the section from the master roll 6 to the web guide beam 21. The rotation of the master roll 6 is stopped. At the time of feeding speed control, a change in the diameter of the master winding 6 is detected by the master winding diameter detecting device 11, so that the PLC feeds the paper W fed from the master winding 6 based on the detection signal of the master winding diameter. The rotation speed of the inverter motor 51 of the master winding rotating device 8 is controlled so that the speed becomes a constant appropriate speed.

When flat paper W is obtained in the section from the master roll 6 to the web guide beam 21, as shown in FIG.
The air cylinder 34 is operated to draw the paper holding beam 31 toward the web guide beam 21. Thereby, as shown in FIGS. 6 and 7, the web guide beam 21 and the paper holding beam 31 sandwich the paper W. That is, the paper W is
Over the entire width, the web guide 21A on the web guide beam 21 side and the paper press 36 on the paper press beam 31 side.
And sandwiched between. At this time, the paper W is supported by being in full contact with the web support 24 at the upper side of the web guide beam 21.

However, when the master winding 6 is rotated forward, reversely or stopped. Engages the gear coupling 60 and the reel spool 9 as shown in FIG. In addition, the parent roll storage stand 4 of the parent roll 6
As shown in FIG. 10 (a), when entering or leaving
The engagement between the gear coupling 60 and the reel spool 9 is released.

As described above, when the flat paper W having no wrinkles or slacks is sandwiched between the web guide beam 21 and the paper holding beam 31, in parallel with this step or next to this step, FIG. As shown, the tape applicator 37 is moved to the drive-side end of the paper holding beam 31. Of course, at this time, the tape applicator 37 is at the operation side end of the paper press beam 31 as shown in FIG. 11, and the double-sided adhesive tape 84 is not pressed against the paper W.

As described above, the state in which the tape applicator 37 has moved to the drive-side end of the paper presser beam 31 [FIG.
13 (a) and 13 (b)], the tape applicator 37 is slightly moved to the operation side by the air cylinder 85 as shown in FIGS. The double-sided adhesive tape fed from 82 is pressed onto the paper W (see FIG. 15).

Then, the tape applicator 37 is pressed out of the tape applicator 37 as shown in FIG. 13D while the double-sided adhesive tape 84 is fed out from the tape feeding reel 82 by the tape applying roller 81 and the double-sided adhesive tape 84 is pressed onto the paper W. The beam 31 is moved to the operation side end. At this time, a peeling layer called a separator of the double-sided adhesive tape 84 fed from the reel 82 by the reel 83 is continuously wound up.

Thus, the pressure-sensitive adhesive layer 84 G of the double-sided adhesive tape 84 is linearly transferred onto the paper W in a band shape. When the tape applicator 37 moves to the operation side end of the paper holding beam 31, the tape application roller 81 is separated from the paper W surface by the air cylinder 86 as shown in FIG.
A series of tape attaching processes ends. Next, FIGS.
As shown in (1), the cutting device 30 cuts an unnecessary portion of the leading end portion W1 of the paper W before the portion where the adhesive layer 84G of the double-sided adhesive tape 84 is attached. That is, by controlling the operating air of the air cylinder 25 and moving the platform 27, the knife 29 in the state shown in FIG. 17 is pushed out as shown in FIG. An unnecessary portion of the cut paper W falls into the lower broke pulpper 7 and is subjected to a dissolving process.

Then, the adhesive layer 8 of the double-sided adhesive tape is applied to the paper W.
After the transfer of 4G, as shown in FIG. 19, the web guide beam 21 and the paper holding beam 31 are opened, the master winding 6 is reversed, and the position of the adhesive layer 84G is controlled to the position of 8 o'clock of the clock. This completes the splicing preparation process. The master winding 6 for which the paper splicing preparation is completed is sent to the next step, the winder 2, and is adhered to the core (winding core) 103 by the winder drum 102, and is wound around the shipping roll 101 (FIG. 20). reference).

In the splicing preparation apparatus, the splicing preparation can be performed in this manner, and the following effects can be obtained. That is, the diameter of the master winding formed by the reel part of the paper machine is, for example, 3200 mm to 2000 m.
m, the diameter of the parent roll 6 is measured at the beginning of the splicing preparation process, and based on this measurement signal,
The position of a related device such as a web guide beam and a paper holding beam for removing defective paper from the master roll 6 and attaching a double-sided adhesive tape can be moved to an optimum position.

Further, by using the measurement signal of the diameter of the master wrap 6, the paper W is fed out from the master wrap 6, or the master wrap 6 is reversed in the last step and transferred to the leading end W1 of the paper W. In order to control the adhesive position to the optimum position, the parent winding rotation speed can be controlled to the optimum value. Further, since the configuration is such that the web guide beam and the paper holding beam can be moved to the optimum position by one motor shared, there is an advantage that the configuration of the apparatus can be simplified and the control of the apparatus can be simplified.

Further, since the paper holding hem is pressed against or separated from the web guide beam, defective paper can be fed from the master winding 6 to the broke pulp 7, Adhesion of the double-sided adhesive tape and cutting of an unnecessary portion of the leading end portion W1 of the paper W can be easily performed. In addition,
The arrangement of the broke pulper as shown in FIG. 1 does not mean that an arrangement for pulling the paper unwound from the parent roll by the air jet effect and removing wrinkles is not considered as an alternative. It most efficiently satisfies the need in the splicing preparation process compared to alternatives.

Further, the entire splicing preparation device can be made compact without requiring a special arrangement space or shape for a device for transporting a master winding from a reel part to an unwinder using a gradient rail which has been widely used in the past. Since they are co-located, it is possible to carry in and carry out the parent roll that runs into the paper splicing preparation process efficiently and safely. The description of the control device for the movement of the device is omitted, but if the above-described device configuration is understood and a control device such as a commercially available standardized sensor or PLC is used, the operator is disposed on the operation panel. It is possible at the ordinary technical level to be able to operate all movements by simply pressing a switch.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the spirit of the present invention. Only the section may be applied. For example, the bonding material is not limited to the double-sided adhesive tape 84, and for example, an adhesive may be used. In this case, instead of the tape applicator 37, a roller or the like for applying an adhesive is provided, and the roller or the like is moved along the paper holding beam 31 similarly to the tape applicator 37. The adhesive can be automatically applied to the paper W surface.
