Further, one end 68a of the tab 68 is provided on both sides of the tab 68 for the paper roll 1.
A triangular notch 86 is formed so that the two shapes substantially match each other when attached to the tip of the substantially V-shaped starting end portion.

The protective paper container 70 for tabs is a protective paper box 7 with an open top for storing the protective paper 84 on the back side of the peeled tab 68.
0 ', etc., and is attached to the traveling body 76 at a position below one side of the tab box 73. Protective paper box 70 '
Has a side wall or a bottom wall that can be opened and closed so that the stored protective paper 84 can be easily taken.

As shown in FIG. 14, the protective paper stripper 71 is composed of a plate-shaped scraper 71 'having elasticity, and its base end is fixed to the upper side wall of the protective paper box 70'. Also, scraper
71 'has a wedge-shaped tip,
The tab 68 whose suction end is held by the vacuum suction plate 91 of the tab holding and pasting device 72 to be described later when the wedge-shaped tip of the scraper 71 'is moved when the 76 is moved.
And the protective paper 84 on the back side are inserted.

As shown in FIG. 10, the tab holding and pasting device 72 includes a drive shaft 88 rotatably supported by a bracket 87 fixed to a fixed plate 57.
A swing arm 89 having one end fixed to the drive shaft 88, and a driven shaft 90 rotatably supported on the other end of the swing arm 89.
And the tab 68 in the tab box 73 attached to the driven shaft 90.
A vacuum suction plate 91 for sucking each of the sheets, a vacuum pump (not shown) connected to the vacuum suction plate 91, and a swing arm 89 to rotate the vacuum suction plate 91 to the tab suction position (broken line in FIG. 10). position)
And the tab attaching position (the position indicated by the alternate long and short dash line in FIG. 10). The driving device 92 and the like displace the tab holding and attaching device 72.
One piece of 68 is sucked and held, and this is moved to the substantially V-shaped starting end side of the paper roll 1 fed on the table 2, and one end 68a of the tab 68 is attached to the upper surface of the leading end of the starting end. .

Further, the vacuum suction disk 91 has a stepped suction surface for sucking the tab 68, that is, a lower surface, as shown in FIG.
It is devised so that the other end 68b of the tab 68 does not adhere to the table 2 when the one end 68a of the 68 is pressed against the substantially V-shaped starting end of the web 1. Therefore, in the case of rewinding the leading end portion of the paper roll 1 to which the tab 68 is adhered, the other end portion 68b of the tab 68 adheres to the table 2 in combination with the floating action of the air ejection device described above. There is no such inconvenience.

Further, the drive device 92 is provided between the bracket 87 and the drive shaft 88 to rotate the swing arm 89 by a predetermined amount.
And the vacuum suction board 91 reaches the tab suction position and the tab sticking position in a predetermined posture (horizontal posture).
It is composed of a chain transmission mechanism 94 for rotating the vacuum suction plate 91 with respect to the swing arm 89 by a predetermined amount when the 89 is rotated.

Incidentally, in FIGS. 10 and 11, 95 is a guide bar of the mount,
96 is a position detection switch, 97 is a protective cover, and 98 is a tension sprocket.

Then, in the tab attaching device 5, the approximate V of the paper roll 1 is
When the tab 68 is attached to the character-shaped starting end, the tab box 73 is first moved by the drive device 79 from the tab replenishment position to the tab supply position (see FIG. 14).

When the tab box 73 reaches the tab feeding position, the tab box
The tab 68 in 73 is pushed upward by the cylinder 75,
Only the topmost tab 68 is suction-held by the vacuum suction disc 91 located at the tab suction position (see FIG. 15). At this time,
The wedge-shaped tip of the scraper 71 ′ is located on the upper surface of one end of the protective paper 84 on the back surface side protruding from the one end 68 a of the tab 68.

When the vacuum suction board 91 sucks and holds the tab 68, the traveling body 76, the tab box 73 and the like are moved from the tab supply position to the tab supply position by the drive device 79 in this state. Along with this, the scraper 71 'moves and its wedge-shaped tip is inserted between the tab 68 and the protective paper 84 on the back surface side, and the protective paper 84 is sequentially peeled off by the scraper 71' (see FIG. 16). ). still,
The peeled protective paper 84 falls into the protective paper box 70 'and is stored (see FIG. 17).

When the protective paper 84 of the tab 68 is peeled off, the swing arm 89 is rotated by the driving device 92 to displace the vacuum suction plate 91 from the tab suction position to the tab attachment position.

When the tab 68 reaches the tab attaching position, the one end portion 68a is attached to the upper surface of the tip of the substantially V-shaped starting end portion of the web 1 on the table 2 by the pressing action of the vacuum suction disk 91 (see FIG. 17). .
At this time, since the suction surface (lower surface) of the vacuum suction disk 91 is formed with steps, the other end portion 68b of the tab 68 does not adhere to the table 2.

In this way, the tab 68 is attached to the substantially V-shaped starting end of the web 1.

Next, a case where the automatic splicing pretreatment device performs a splicing pretreatment on the web 1 will be described.

The web 1 conveyed to the vicinity of the table 2 by the truck 9 is rotatably supported by the support device 3, and the outer surface layer of the web 1 is adsorbed upward by the suction disc 99 provided on the support frame 30 above the web 1. After that, the surface layer portion is cut in the width direction by the cutter blade 100 also provided on the support frame 30 (see FIG. 18).

When the surface layer portion of the paper roll 1 is cut in the width direction, the surface layer portion is removed, and the paper roll 1 is rotated by the support device 3 so that the starting end portion is extended to the mounting surface of the table 2 and the starting end portion is vacuum-sucked. It is suction-fixed to the mounting surface of the table 2 by the device (see FIG. 19).

When the start end of the paper roll 1 is sucked and fixed to the table 2, the pair of main processors 4 move along the guide body 29, and the substantially V-shaped cut 101 and the adhesive layer (double-sided adhesive tape 37) are provided at the start end. Are formed (see FIG. 20).

After that, the apex portion of the substantially V-shaped starting end portion of the paper roll 1 is cut by the cross cutting cutter device 56 (see FIG. 20).

Then, the starting end portion of the paper roll 1 is cut off along the cut line 101 (see FIG. 21). The separated starting end is collected by a damaged paper collection cart (not shown).

When the start end is cut off, the tab attaching device 5
One end portion 68a of 68 is attached to the top surface of the tip of the substantially V-shaped starting end portion (see FIG. 22). At this time, since the suction surface (lower surface) of the vacuum suction disk 91 is formed with steps, one end of the tab 68 is
Only 68a is attached to the starting end portion, and the other end portion 68b is not attached to the table 2.

When the tab 68 is attached to the front end of the web 1, the support frame
The start end of the paper roll 1 is unwound and rewound while being squeezed in the winding direction by the compressed air ejected from the nozzle 102 provided at 30, and the other end 68b of the tab 68 is attached to the outer surface of the body of the web 1 ( (See Figure 23). When the starting end portion of the paper roll 1 is rewound, air is ejected upward from the table 2 to prevent the other end portion 68b of the tab 68 from adhering to the upper surface of the table 2.

In this way, the pretreatment for splicing the web 1 is performed.

The operation of each device is automatically performed according to a preset signal from a control device (not shown).

Thus, the web 1 that has been subjected to the pre-processing for paper splicing is rotated at a speed equal to the feeding speed of the web 1 that is being supplied to the rotary press, and the end of the web 1 that is being fed is replaced with a new web 1. When pressed to the start end of the paper, both webs 1 are adhesively connected by the adhesive layer and the adhesive layer 67 on the surface side of the tab 68, and the tab 68
Is cut along the cut 85 formed in the tab 68 as shown in FIG. 25, and the starting end of the new web 1 is continuously fed to the rotary press. At this time, it goes without saying that the protective paper of each adhesive layer is peeled off.

(Effects of the Invention) The present invention, having the above-mentioned configuration, has the following advantages.

(1) A pair of main processors for forming a substantially V-shaped cut and an adhesive layer at the starting end of the paper roll are arranged above the table.
Since both main processors form the cuts and the adhesive layer, compared to the conventional automatic paper splicing pretreatment device that uses one main processor to form the cuts and the adhesive layer The layers can be formed quickly. As a result, the work efficiency of pretreatment for paper splicing can be significantly improved.

(2) Since the table is equipped with a vacuum suction device that suction-fixes the starting end of the paper roll on the table, when the main processor forms a cut and an adhesive layer on the starting end of the paper roll, the starting end may be misaligned. Alternatively, there is no wrinkling at the starting end portion, and the notch and the adhesive layer can be satisfactorily and reliably formed at a predetermined position of the starting end portion.

Further, since the vacuum suction device has a plurality of suction zones,
Only suitable suction zones can be used depending on the width of the web. That is, since only the suction zone located below the starting end of the web can be used, air will not leak from the small holes in the suction zone. As a result, regardless of the width of the paper roll, the starting end portion of the paper roll can be reliably sucked and fixed onto the table.

(3) Since the table is provided with the air ejecting device that floats the starting end of the paper roll from the mounting surface, when the starting end of the paper roll fed to the mounting surface of the table is rewound, one end is added to the starting end. It is possible to prevent the other end of the tab to which is attached from adhering to the mounting surface of the table. As a result, there is no possibility that the other end of the tab is adhered to the table and the web or tab is damaged when the web is rewound.

(4) Since the supporting device for the paper roll is arranged at the lower position of the table, the device itself can be made compact as compared with the conventional automatic paper joint pretreatment device using the gate-shaped supporting device. The installation space is small.

(5) Since the vacuum suction board of the tab attaching device has a stepped suction surface for sucking the tab, when the one end of the tab is pressed against the substantially V-shaped starting end of the paper roll, the other end of the tab is pressed. The part can be prevented from adhering to the table. As a result, in the case of rewinding the leading end portion of the paper roll to which the tab is adhered, in combination with the floating action by the air ejection device described above,
There is no inconvenience that the other end of the tab adheres to the table.

(6) Since the tabs placed in the laminated form have the adhesive layer and the protective paper on the front and back surfaces, even if these tabs are placed in the laminated form, one sheet can be surely addressed by the vacuum suction board. Can be adsorbed. As a result, there is no mistake in tab holding and holding by the vacuum sucker.
