(Example) Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, (11 is an unwinding machine, (2) is a winding machine with a slitter, (3) is a roll product take-out device,
The sheet material (S) unwound from the unwinding machine (1) is cut into equal lengths by the slitter of the winding machine (2), and then cut into core tubes (5 ) is wound around a predetermined length to obtain a roll product (R).

The structure of the winding section of the winding machine (2) utilizes a conventionally known device, and the details are omitted from illustration, but as shown in the main part in Fig. 4, there are two A pair of winding chucks +6), (6) are connected to an air cylinder (9), (
The winding shaft (4) is connected to the winding shaft (4) so that they are coaxially opposed to each other and movable toward and away from each other.
Both ends of the chuck (6
) has a structure in which a shaft with a drive gear 01 is connected to the rod supporting the chuck (6), and rotational force is applied to this chuck (6), while the other chuck (6) rotates around its own axis. It is formed to rotate freely.

The winding shaft (4) gripped by the winding chucks (6), (6) having the above-mentioned structure is a winding shaft (4) generally known as an air shaft, which is a hollow shaft into which an air bag is inserted. 4
) is used, and this winding shaft (4) has a plurality of holes bored in the outer periphery of the core tube (5) into which a paper tube, for example, is inserted, and the winding shaft (4) has a plurality of holes formed on the outer circumference in which a core tube (5), for example, a paper tube, is inserted. It has a structure in which a lug aD, which is retracted by contraction caused by compressed air extraction, is disposed in relation to each hole, and when the lug αυ protrudes, the winding shaft (4) and the core pipe (5) are connected to each other. Tighten and integrate the winding shaft (4)
The rotation of the lug αD is directly transmitted to the core tube (5), and winding can be performed without any slippage.On the other hand, when the lug αD is retracted, the winding shaft (4) and the core tube (5) are The core tube (5) is formed in a loosely fitted state so that the core tube (5) can be easily removed.

Note that the winding shaft (4) is not limited to such a structure, and may have a structure that allows the core tube (5) to be fitted under tight conditions, and that allows the core tube (5) to be loosely fitted when loosened. Needless to say, it can be applied if it is.

Next, the main structure of the roll product take-out device (3) is shown in Figs. The components are moved forward and backward in a synchronized manner between the take-out position (0) behind the winding position (A) and the take-down position (C) further behind the winding position (A). It is arranged so that it can move back and forth.

The roll product take-out device (3) is configured to carry out the repositioning (I
I) A pair of rails (12^), (12 m) installed at a high position extending from left to right on both sides between I) and (A) and extending parallel to the front and rear directions, and each rail (12 m).
There are sliding bodies (13A) and (13m) that move back and forth in synchronization guided by (12,), and an arm Q extending linearly from one sliding body (13A).
4) is installed vertically, and two bearings α are attached to this arm (14).
One is fixed.

The bearing QJ has one shaft hole in the center, and this shaft hole Qll has a horizontal hole structure that opens forward on the winding machine (2) side and supports the winding shaft (4). The center line lies horizontally in the left-right direction perpendicular to the longitudinal movement direction of the bearing (5), and is provided so as to be at the same level as the winding center of the upper and lower two-stage arrangement at the winding position W<4).

Furthermore, a shaft restraining mechanism (17) is attached to the bearing α, and this shaft restraining mechanism aη is connected to the shaft hole ae of the bearing Q.
It is formed from a roller (2) that is eccentrically fitted into a support bottle installed near the surrounding opening, and a handle α with its end fixed to the support bottle, as shown in Fig. 5 ( As shown in (a) to (c), when the handle QJ is tilted backward, the roller Ql enters the cavity formed in the bearing 051 and is in a position where it escapes from the shaft hole αe, while the handle Q18)
When the roller agr is rotated and tilted forward, the roller agr comes out of the space and is in a position where it partially protrudes into the shaft hole Q[9, and the protrusion shown in Fig. 5(C) In this state, the roller α acts to restrict the movement of the end of the winding shaft (4) inserted in the shaft hole α so that the roller α cannot be pulled out from the opening side. The state shown in (<) and (b) is the released state, and the state shown in FIG. 5 (c) is the restrained state.

Thus arm 04J1 bearing a! 9 and shaft restraint mechanism a
η constitutes a winding shaft holder (7).

1 is installed vertically so that it can swing in the front and back direction, and this four-bar link C
Hooks (21) are attached to the lower end of 211 in two stages, upper and lower.

The hook (21) is connected to the lower end of the vertically extending base and has a hook shape with a curved portion extending forward toward the winder (2), and similarly to the bearing α, it is moved by forward movement. The winding shaft (41), which is fixed horizontally on the left and right sides, can be supported so as to embrace it, and by swinging the four-bar link (A) rearward as shown in Figure 7. , the fixed winding can be moved relative to the shaft (4) from a supported position to a released position.

Therefore, the two hooks (21) have a support center line of 4
In the state where the joint QΦ is hanging down, each bearing 09
It is positioned so that it is concentric with the support center line of the 4-bar link (2I).

Note that (25) in FIG. 2 indicates an actuator for swinging the four-bar link QΦ.

Next, air is removed from the air bag of the winding shaft (4), and the core tube (
5) into a loosely fitted state in preparation for the operation of removing and removing the winding shaft (4) (see FIG. 10).

After that, 4 verses c! The winder is swung backwards to release the support of the winding shaft (4) by the hook (21) and move the hook (21) to the retracted position.

In this way, the winding shaft (4) is supported on one side by the bearing Q9, and when the carrier (22) is then moved, the rolled product (R) is transferred to the carrier (22) as shown in FIG.
) is removed from the take-up shaft (4) while still being mounted on the cradle (23).

The carrier (22) is moved in a straight line to the front of the packaging table (24) and then transferred onto the table.

On the other hand, fit the broken core tube (5) into the winding shaft (4) with the bearing QSI supported on one side (see Figure 12), then swing the four-bar link (A) to its original hanging position and hook it up. (21)
At the same time, air is injected into the air bag of the winding shaft (4) to fit the core tube (5) (see FIG. 13).

After that, the take-up shaft holder (7) and the take-up bearing are attached to the body (8).
is moved forward to the take-out position (u), the winding chuck (61, (6) is gripped, and the winding shaft holder (7) and the winding bearing move the body (8) backward. Then, the winding shaft (4) is in the state shown in Fig. 14 with both ends gripped by both chucks (6) and +61, and is ready for the next winding, while the winding shaft holder (7) and winding The bearing is body (
8) retreats to the unloading position (c) and waits in preparation for the next unloading process.

Thus, the series of roll product unloading operations is completed.

(Effect of the invention) Continuing on, the effects of the present invention are as follows.
