A guide groove that fits into the fixed rail 31 (see FIG. 1) is provided, and a pair of coupling portions 2c each having an internal gear formed inside is provided outside the guide groove. In addition, a rotational driving force for winding the paper 10 is transmitted to the spool 2 by forming an external gear of a rotation driving device (not shown) in the coupling portion 2c to form a gear joint.

The fixed rail 31 is inclined slightly downward toward the downstream side (the left side in FIG. 1), and as shown in FIG. The rolled base paper 11 is moved by the bearing 2b (see FIG. 3) of the spool 2 on the roll 2 to the roll base paper transporting unit 30, which is an extension of the fixed rail 31.
In this part 30, the fixed rail 31 is provided with a U-shaped stopper 13 at an appropriate interval.
Is rotated by the cylinder 14 to stop or pay out the roll base paper 11 on the stopper 13 to regulate its position. Thus, the roll base paper 11 sequentially moves to the downstream side.

Downstream of the roll base paper transport section 30, there is an unwinder 15. The unwinder 15 receives the roll base paper 11 moved from the roll base paper transport section 30, rewinds the paper, and winds the paper (not shown). To supply. Between the roll paper transport unit 30 and the unwinder 15,
A remaining paper processing device 70 is provided, and a spool collection line 50 is provided above the remaining paper processing device 70. Further, in the middle of the spool collection line 50, a fixed rail 3
1, a spool elevating device 60 that supplies the spool 22 with remaining paper to the remaining paper processing device 70 is provided.

The spool 22 that has been spliced by the unwinder 15 moves to a spool collection line 50 and is moved by a spool elevating device 60 to a lower roll base paper transport section 30.
After the remaining paper is removed by the remaining paper processing device 70, the returned paper is returned to the spool collection line 50 and moved to the reel stand 1 side. In the present embodiment, the spool collection line 50 also serves as the spool storage unit 3 (see FIG. 6) of the conventional example.

A support base 16 is provided downstream of the roll base paper transport section 30. On the support base 16, the roll base paper 11 is received from the roll base paper transport section 30 and rewound. A support 17 is erected adjacent to the support 16.
A lifting frame 62 (see FIG. 2) that can be raised and lowered
The support arm 18 supports the coupling portion 2c (see FIG. 3) of the spool 2 via the lifting frame 62. When the rewinding of the roll base paper 11 is completed, the paper 21 is lifted up by the support arm 18 while being fed out (see the roll base paper 20 in FIG. 1).
The succeeding new roll base paper 11 is placed on the empty support 16.
Supply. Then, the paper 21 unwound from the roll base paper 20 immediately before the end of the rewinding by the web joining means 19.
Then, the leading end of a new roll base paper 11 is connected, and the paper 21 on the roll base paper 20 side is cut by a cutter (not shown).
In this way, the new and old base papers are connected to form the roll base paper 11.
Continue rewinding. The vertical movement of the support arm 18 can be moved up and down to a position higher than the paper splicing position.
2 can be handed over.

The spool collection line 50 basically has the same function as the roll base paper transport section 30, and has a fixed rail 51 which is slightly inclined downward in the direction of the reel stand 1. The stoppers 13 are provided on the fixed rail 51 at appropriate intervals in the same manner as the roll base paper transport unit 30.
(Not shown). At an appropriate timing, the spools 22, 2 are sequentially sent to the downstream side. At the end of the fixed rail 51 on the paper joining portion side, as shown in FIGS.
A rotatable rail 52 that can be rotated by degrees is supported by a hinge 53. In the middle of the fixed rail 51, a similar rotating rail 54 is provided at the position of the spool elevating device 60 so as to be rotatable inward about the hinge 55.

The spool lifting device 60 will be described.
The support columns 61 are erected on both sides of the roll base paper transport section 30 and the spool collection line 50, and support the lifting frame 62 so as to be slidable in the vertical direction. Also, on the support 61,
As shown in FIGS. 4 and 5, an upper sprocket 64 and a lower sprocket 65 are attached to the upper and lower sides, respectively, and a chain 63 connected to an elevating frame 62 is wound around both. An elevating motor 66 is mounted on the upper surface of the column 61, and the driving force of the motor 66 is transmitted to sprockets 64 and 65 via a chain, and the elevating frame 6 is moved.
2 up and down. The lifting frame 62 is provided with a spool receiver 67 made of a rotatable roller.
It supports two or two coupling parts 2c (see FIG. 3).

The remaining sheet processing device 70 will be described. An arm 73 having one end rotatably supported and a two-row sprocket 77 are coaxially connected to a column shaft 71 provided on the side surface of the column 61 and rotatably mounted. A shaft 74 is rotatably attached to the other end of the arm 73.
4, a sprocket 75 and a driving roller 76 are coaxially connected and mounted. On the side of the support 61, a support shaft 7
1, a drive motor 80 having a sprocket
(See FIGS. 2 and 5). A chain 79 is wound around this sprocket and one of the sprockets 77, and the other of the sprocket 77 and the sprocket 7
5 and the chain 78 are wound around. The driving force of the driving motor 80 is transmitted from the sprocket to the chain 79 and the chain 78, and serves as a rotation driving source of the driving roller 76.
The drive roller 74 is connected to the spool 2 positioned by the stopper 13 on the fixed rail 31 of the roll base paper transport unit 30.
In contact with the second and second coupling portions 2c, they are driven to rotate.
A pit 81 for accommodating the discarded remaining paper 22a is disposed below the pit 81 (see FIG. 1). Arm 73
Is connected to the cylinder 72 at an intermediate portion near the shaft 74, and the cylinder 72 swings around the support shaft 71 by the projecting / retracting operation of the cylinder 72 as shown in FIG. Due to this swing, the drive transmission to the coupling portion 2c can be interrupted.

Next, the operation of the present embodiment will be described. By raising the support arm 18, as shown in FIG. 4, the spool 22 that has completed the splicing is lifted to a position slightly higher than the entrance rotating rail 52 of the spool collection line 50. At this time, the rotating rail 52 is rotated outward by 90 degrees so as not to interfere (indicated by a dashed line in FIG. 2). When the spool 22 is lifted to a predetermined position and is aligned with the fixed rail 51, the rotating rail 5
2 is returned to the original position, and after the spool 22 is moved onto the rotating rail 52, the support arm 18 is lowered. The spool 22 rolls on the rotating rail 52 and the fixed rail 51 to the downstream side (the right side in FIG. 4), and sequentially moves toward the spool elevating device 60 while being restricted by the stopper 13 (see FIG. 1). Go. The lifting frame 6 slightly below the rotating rail 54
2 is on standby, and the spool 22 is
0 and reaches a predetermined position on the rotating rail 54, the elevating frame 62 rises, and the spool receiver 67 receives the coupling portion 2c of the spool 22 and
Lift from 4. Thereafter, the rotating rail 54 is rotated inward by 90 degrees and retracted so as not to hinder the lowering of the spool 22 (see FIG. 2). The elevating frame 62 is lowered until the spool 22 rides on the fixed rail 31 of the roll paper transport unit 30. When the user rides on the fixed rail 31, the position is fixed by the stopper 13, so that the spool 22 does not move (see FIG. 5). In this position, the arm 72 is swung by operating the cylinder 72, the drive roller 76 of the remaining sheet processing device 70 is brought into contact with the outer periphery of the coupling portion 2c of the spool 22, and the spool 22 is moved by the motor 80 to the remaining sheet 22a. It rotates in the direction opposite to the winding direction. Thus, the remaining sheet 22a is rewound and discarded in the pit 81 (see FIG. 1). When the remaining paper processing is completed, the empty spool 2 is lifted by the elevating frame 62, returned to the spool collection line 50 by an operation reverse to the above-described operation, and sequentially sent to the reel stand 1.

As described above, according to the present invention, the winding from the reel stand 1 to the unwinder 15
The roll base paper 11 is conveyed until rewinding, and the remaining paper of the spool 22 is processed after the splicing is completed, and a series of processes from returning the empty spool 2 to the reel stand 1 can be automated. Yes, can be omitted. Since the remaining paper processing device 70 is provided not in the middle of the spool collection line 50 arranged in the upper part of the facility but in the middle of the roll base paper transport unit 30 arranged in the lower part of the facility, the spool collection line 50 and the roll The space partitioned by the transport unit 30 can be effectively used, and the size of the facility itself can be reduced. Further, the pit 81 for discarding the remaining paper 22a can be arranged below the equipment, and handling such as maintenance of the pit 81 becomes easy.

The arrangement according to the invention has yet another advantage. According to the specification change of the paper 10 manufactured on the upstream side, for example, a change in the basis weight, a considerable amount of defective paper is inevitably generated in the transition process, but according to the present embodiment, only the defective portion is replaced by another paper. It is possible to employ a method in which the spool is wound on a spool (hereinafter referred to as a defective reel), and when good paper starts to be output, the spool is further wound on another spool 2. In the conventional case shown in FIG. 6, immediately after the defective reel is taken up, it is detached from the machine by a crane or the like, and is rewound by a remaining sheet processing device provided outside the machine. The work of returning was necessary. But,
According to the present embodiment, even such a defective reel can be handled in the same manner as the normal roll base paper 11. That is, the defective reels of the reel stand 1 are sequentially transported on the roll base paper transporting section 30 and, when they reach the position of the remaining paper processing device 70, the remaining paper is processed by the remaining paper processing device 70 and the spool is moved up and down in the same manner as the spool 22. The operation of returning to the spool collection line 50 can be performed by the device 60, and there is no need to separately perform useless work such as removal by a crane, and the defective reel can be processed in an orderly manner.
