Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a web winding device for paper, plastic film, metal foil, etc.

[Prior Art] Conventionally, a web winding device as described in Japanese Patent Publication No. 62-60337 has been proposed. This web winding device has a first
and a second pair of winding drums are placed side by side, and have cores that are carried in and out of the upper surface valleys of both winding drums, and the cores are moved by rotating both winding drums in the winding direction. The core is rotated, and the web introduced from the web introduction section sandwiched between the lower surfaces of both winding drums is wound around the core.

[The problem that the invention tries to solve! I] However, the above-mentioned prior art has the following problems (1) to (2).

■In the conventional technology, after the winding roll that has finished winding the web around the core is discharged onto the cradle from both winding drums, the web that continues to the end of the winding roll (the starting end for the next winding) is discharged onto the cradle. The part) is pressed against the adhesive layer on the new core and bonded, and then the terminal end of the winding roll is cut at a position close to the bonded part.

Therefore, before the new core is carried into the upper surface troughs of both winding drums, the winding start end of the web is glued, and as a result, the new core is carried into the upper surface troughs of both winding drums. In some cases, a complicated control operation is required to pull the web back toward the original roll while the new core is being carried in.

Further, the end portions of the winding roll are cut off after being discharged onto the cradle from both winding drums. The work of gluing this end portion onto the take-up roll must be done manually off-line, resulting in poor workability and operability.

■The conventional technology does not include a waste paper processing device within the winding device. When a web of a certain diameter has been wound around the core and the winding roll is discharged from both winding drums onto the cradle, the remaining diameter of the web roll becomes less than a certain level, and the web roll is If the remaining web (terminal web) cannot be formed into a winding roll with a predetermined constant diameter, the remaining web is continuously pulled out manually from both winding drums to the cradle side. Paper processing is required, resulting in poor workability and operability.

Incidentally, since the cradle-side space serves as a discharge path for the take-up roll, it is extremely difficult to install a mechanical waste paper processing device here in terms of space.

(2) In the prior art, as mentioned in (2) above, paper waste is manually processed online at the final stage when the original roll is used up in each country.

Therefore, it is impossible to realize automatic operation of the winding device, which automatically replenishes raw rolls one after another, continuously winds up winding rolls of a constant diameter one after another, and unloads the winding rolls.

An object of the present invention is to easily adhere the winding start end of a web to a core, and to easily adhere the terminal end of a winding roll to the winding roll online.

An object of the present invention is to mechanically process defective webs, such as residual webs below a certain level on a raw roll, in a winding device.

The web 1 is slit from the raw roll 2 to a predetermined width by a slitter 16 disposed in the web feeding line 15, and then passed through the web introducing section 14 to the core 13.
When a certain amount of winding is completed, it is discharged to the cradle 17 side.

At this time, both winding drums 11 and 12 are supported by the pedestal 10A and driven by a drive motor (not shown).

Further, the core 13 is attached to a core holder 1 fixed to a swing arm 18 that swings around the rotation axis of the first winding drum 11.
The core holder 19 is held in the core holder 9 and is transferred by the swing of the swing arm 18 toward the valleys on the upper surfaces of both winding drums 11 and 12, and then carried into the valleys from the core holder 19 by opening the holder cylinder 20.

Further, both end shaft portions of the core 13 carried into the upper surface troughs of both winding drums 11 and 12 are chucked by a core chuck 21. The core chuck 21 is configured to move the mount 10 according to the thickness of the winding roll 3 generated around the core 13.
It is raised along the slight guide 22 provided at A. The lifting operation of the core chuck 21 is performed by a chuck lifting cylinder 23 operated via a group of pulleys.

Furthermore, a rider roll 24 is provided on the upper surface of the core 13. The rider roll 24 applies nip pressure to the take-up roll 3 wound around the core 13. The rider roll 24 is mounted on the frame 10 according to the thickness of the take-up roll 3 around the core 13.
It is made to rise within A. The lifting motion of the rider roll 24 is performed by a rider lifting cylinder 25 operated via a group of pulleys.

Further, the pedestal 10A is provided with a take-up roll discharge cylinder 26. The take-up roll discharge cylinder 26 drives the discharge arm 27 and pushes out the take-up roll 3, which has been completely wound around the core 13, from the upper surface troughs of both the winding drums 11 and 12 toward the cradle 17. Discharge.

Further, the web feeding line 15 includes a first pinch roll 31,
and a second pinch roll 32, and these pinch rolls 31 and 32 apply an unwinding force to the web 1 being unwound from the raw roll 2.

Further, the web feeding line 15 is provided with an under-drum sheet passing conveyor 33 and a comb-shaped guide 34 in the web introduction section 14 around the first winding tram 11 .

Then, the starting end of the web 1 that is started to be wound around the core 13 from the web introducing section 14 is passed through the paper passing conveyor 33 and the comb-shaped guide 34 so as to be wound around the first winding tram 11. The starting end is guided to a pressure point between the first winding drum 11 and the core 13 (as described later, an adhesive point where the adhesive supplied to the starting end adheres to the core 13).

In addition, the drum lower paper passing conveyor 33 has a swing center 33A.
It swings around and waits at a position away from the first winding drum 11 except when winding the web 1 around the core 13 starts and ends.

Furthermore, the web feed line 15 is equipped with a web cutting device 35. The web cutting device 35 has a disc-shaped cutting blade 36
The starting end or the ending end of the web 1 is cut and formed on the inlet side of the under-drum paper passing conveyor 33 and the comb-shaped guide 34. When the web cutting device 35 cuts, the web feeding line 15 stops feeding the web 1. however,
When the web cutting bag [35 is of a traveling cutting type, the web cutting device 35 can cut the web 1 without stopping the feeding of the web 1 by the web feeding line 15.

Furthermore, a web cutting device 3 in the web feeding line 15
A waste paper slitter 41 and a waste paper conveyor 42 constituting a defective web processing device are disposed downstream of the waste paper conveyor 5 . That is, at the stage where the web 1 of a constant diameter has been wound around the core 13 and the winding end portion of the web 1 is cut by the web cutting device 35, the remaining web of the raw roll 2 has a predetermined constant diameter. When the following occurs, the under-drum paper passing conveyor 33 swings around the swing center 33A from the normal guide position around the first winding drum 11 to the input side of the waste paper slitter 41, and as a result, the original paper roll The second remaining web is continuously fed to a waste paper slitter 41, slit, and then discharged by a waste paper conveyor 42.

Furthermore, a splicing device 51 is disposed at the most upstream side of the web feeding line 15. Splice device 5
1 has a known structure, in which the tip of the new roll 2B is automatically connected to the end of the old roll 2A, and the webs 1 of the rolls 2A and 2B are continuously fed. It is drawn out to the feed line 15. In the figure, reference numeral 2C indicates a new roll of fabric on standby, which is set at the splice position by a carry-in arm 53 driven by a carry-in cylinder 52. In addition, in the figure, 54 is a web cutting device, and 55 is a press roll, which move to the new fabric roll 2B side when the remaining diameter of the old fabric roll 2A becomes the minimum, and removes the old fabric roll. The web 1 still being unwound from the web 2A is cut by the web cutting device 54, and the web 1 is pressed against the new fabric roll 2B by the press roll 55, and the end portion of the web 1 is preliminarily cut at the starting end of the new fabric roll 2B. The splice is performed by pressing the double-sided adhesive tape 56 on the part.

However, the web winding device 10 has the following effects (1) to (2).

■The web 1 fed into the web introduction section 14 between the rewinding trams 11 and 12 on the web feeding line 15 is cut off at its starting end by a web cutting device 35 disposed on the line 15, if necessary. The adhesive nozzle 39 supplies adhesive to the starting end. The starting end of the web 1 supplied with this adhesive is supplied around the core 13 from the web introducing section 14 and is easily adhered to the core 13 via the adhesive.

Furthermore, the end portion of the winding roll 3 that has been completely wound around the core 13 on the rewinding drum 11.12 is subjected to the above-mentioned process before being introduced into the web introduction section 14 of the winding drum 11.12. The web cutting device f35 cuts the following web 1 on the roll side, and the adhesive nozzle 39 supplies adhesive to the end portion thereof. The end portion of the web 1 supplied with this adhesive is supplied around the core 13 from the web introduction section 14 and easily adhered to the winding roll 3 via the adhesive.
