Each operation can also be performed manually.

Operating means such as push buttons are provided.

Next, the operation of the apparatus having the above configuration will be explained.

The roll material 5 prepared for gluing is placed on the pallet 6 on the fixing station 7 in advance.

As shown in FIG. 11 (-), the web is being fed into the printing press from the roll material 5a held at one end of the turret arm 17 of the paper feeding device.At this time, the lifting platform 50 of the table lifter 3 is lowered. It is in the waiting position.

Moreover, the lifting platform 50 is held at the center by a centering device 63 (see FIG. 7).

The roll material supply operation is started at an appropriate timing while the web is being fed from the roll material 5a.

Note that this operation may be started by the operator pressing a start button.

First, the unmanned cart 4 transports a new roll material 5 from the fixed station 7 to the front of the paper feeder 2 (Fig. 11 (al.
), this transport is performed as follows. Namely.

The unmanned cart 4 stops next to the fixing station 7, and then, as shown in FIG. 10B, the air cylinder 13B is operated to engage the cup-shaped member 13A with the positioning member 14, thereby positioning the two carts 4. In this state, the roller conveyors 8 and 12 rotate in the same direction, and the roll material 5 on the fixing station 7 is transferred, together with the pallet 6, onto the unmanned cart 4. Next, the unmanned cart 4 carrying the roll material 5 travels in front of the table lifter 3 of the paper feeder 2, stops at a predetermined position, and is positioned and fixed as shown in FIG. 10B.

Next, as shown in FIG. 11 (al), the turret arm 17 rotates to a position where the center of the roll material can be detected, and the lifting platform 50 of the table lifter 3 transfers the pallet to the same height as the unmanned cart 4. When the lifting platform 50 rises to the pallet transfer position and stops, the unmanned cart 4 and the lifting platform 5
The roller conveyor 12.52 on the top rotates in the same direction and transfers the pallet 6 holding the roll material 5 onto the lifting platform 50 as shown in FIG.
When it hits the upper pallet stopper 54 and stops,
The roller conhair 12.52 stops rotating. At the same time, the pallet fixing means 54 (see FIG. 6) operates to hold the pallet 6 against the pallet stopper 54. As a result, the pallet 6 and the roll material 5 on it
is positioned and fixed at a predetermined position on the lifting platform 50.

Next, as shown in FIG. 11, the lifting platform 50 descends, and the center of the roll material 5 is placed between the light emitter 53A and the light receiver 53B.
At the point in time when the roll material center detecting means (see FIG. 3) detects the center, the lifting platform 50 stops. Due to this.

After the roll material 5 is positioned at a predetermined chucking position, the centering device 63 (see FIG. 7) is opened to enable horizontal movement of the lifting table 50, and the web guide tuning device W70 is opened. (see FIG. 3) operates to restrain the lifting platform 50. As a result, the lifting platform 50 moves together with the web guide device 39 supporting the turret arm 17, and even though the turret arm 17 is moving left and right to control the web edge, the lifting platform 50 moves in unison with the web guide device 39 supporting the turret arm 17. A constant positional relationship is maintained in the left-right direction (in the axial direction of the roll material) with respect to the turret arm 17.

Next, as shown in FIG. 11+d+, the turret arm 17 rotates and stops at a horizontal position (chucking position). Then, the chucking device 7 operates to chuck the roll material 5.

After chunking, the lifting platform 50 is lowered by a certain amount and the pallet 6 is separated from the roll material 5 2 Then, the remaining core rotation motor 2
7 (see FIG. 4) rotates the roll material 5 and stops the glue at a fixed position. At this time, the position of the glue can be detected by a photoelectric device (not shown) provided on the lifting platform 50. Note that this operation may be performed after the pallet is returned to the unmanned cart 4.

Thereafter, the turret arm 17 rotates again, and as shown in FIG. And centering device 6
3 operates and positions the lifting platform 50 at the center position,
The lifting platform 50 rises to the pallet transfer position.

Next, as shown in FIG. 11 ffl, the roller conveyor 12
52 rotates in the opposite direction to the previous time and returns the balent 6 on the lifting platform 5o to the unmanned cart 4.

After that, the unmanned trolley 4 returns to the side of the fixed station run 7,
The held valent is returned to the fixing station 7.

On the other hand, as shown in FIG. 11fgl, the elevator platform 50 is lowered to the standby position, and the turret arm 17 is returned to the paper feeding position.

The web is continuously supplied from the roll material 5a.

With this, the operation of supplying the new roll material to the paper feeding device is completed.

When the remaining amount of the roll material 5a reaches a predetermined amount, a one-sheet splicing operation is performed. That is, the shaft left arm 17 is
The paper splicing device f41 rotates to the paper splicing position shown in Figure fhl.
After approaching the circumferential surface of the new roll material 5, the predrive device causes the circumferential speed of the roll material 5 to match the running web speed, and the touch roller 43 of the paper splicing device 24 is activated by the 1 paper splicing signal. The running web is pressed against the circumferential surface of the new roll material 5 and bonded (see FIG. 11 0)).

The cutter 45 operates to cut the web (see Figure 11).
)) 1 Paper splicing is performed. As a result, the web from a new roll 5 is supplied to the printing machine (hereinafter, this roll is indicated by reference numeral 5a), and the web has been fed out until now. The roll material becomes a residual core (this residual core is hereinafter referred to as 5b).

Next, the turret arm 17 further rotates and stops at the residual core discharge position shown in FIG. After that, the chucking device opens and discharges the remaining core 5b.The cone at the tip of the cone shaft of the chucking device F1B, 19 (see Fig. 4)
supports the roll material by pressing the tapered surface against the inner surface of the paper tube, but the taper ratio of these cones is different on the left and right, so that the paper tube always remains on one cone when the chucking is released. I have to. Further, the turret arm 17 is provided with a protrusion (not shown) that interferes with the paper tube near the retracting limit of the cone.

This makes it possible to reliably discharge the remaining core of the old roll material.

After the remaining core is discharged, as shown in FIG. 11(E), the normal paper feeding state is restored, and the web is fed from the roll material 5a to the printing machine.

In two or more embodiments, the paper feeding device 2 is provided with a web guide device! ! 39 is provided, and is configured to move the roll material being fed and the turret arm 17 holding it left and right in order to control the edge of the running web.

However, the present invention is not limited to this case, but can also be applied to a paper feeding device that is not provided with the web guide device 39, and in that case, it is not necessary to make the lifting platform 50 movable left and right. Needless to say.

Furthermore, in the above embodiment, a conveyor is provided in each of the unmanned cart 4 and the lifting platform 50 as a means for transferring the pallet 6 between the unmanned cart 4 and the lifting platform 50 of the table lifter 3. It is also possible to use alternative means. 12 and 13 show an embodiment in which a fork device is used to transfer the pallet 6. The unmanned trolley 4a is equipped with a fork device having a fork 80 that can protrude laterally, and the lifting platform 50a has a groove 81 through which the fork 80 passes. In this embodiment, the pallet 6 is held by the fork 80, and the fork 80 is inserted into the groove 81 of the lifting table 50a to transport the pallet 6 onto the lifting table 50a.Then, the lifting table 50a is slightly raised. by holding the pallet 6 on the lifting platform 50a and then retracting the fork 80.

The pallet 6 can be transferred onto the lifting platform 50a.

Further, by performing the reverse operation, it is possible to transfer the pallet from the lifting platform 50a onto the unmanned cart 4a. In addition,
The other configurations are the same as those of the embodiment described above.

Furthermore, FIGS. 14 and 15 show another embodiment, and in this embodiment, the unmanned trolley 4b is provided with a fork device having a fork 82 with a shallow V-shaped recess formed on the upper surface. On the other hand, the elevating table 50b is formed with a groove 83 for passing the fork 82 therethrough, and a shallow 7-shaped recess is formed on the upper surface. In this case, a pallet is not used to transport the roll material 5, and the roll material 5 is directly transferred to the fork 82.
and can be placed on the lifting platform 50b. Here, the recess on the top surface of the lifting platform 50b is as follows.

It also serves as a means for positioning the roll material 5 at a predetermined position, so there is no need to provide a pallet stopper in this embodiment.
