is arranged, and one of the reflection type projectors 25a and 25b is activated with respect to the tip Wa of the polyliner W hanging from the scroll 3, and it is determined whether the polyliner W is wound right-handed or left-handed. It has become.

Next, a specific checking method using the liner check device 8 will be explained with reference to FIGS. 5(a) and Φ) to FIGS. 8(a) and (b).

First, Fig. 5(a). (b) shows the front and back surface detection device 12
This shows a method for determining the front and back sides of the scroll 3 by moving the scroll 3 in the direction of the arrow shown in the figure using the transfer device 5 with the tip of the vibration sensor 11 in contact with the surface of the polyliner W. , and a vibration sensor 1 is mounted on the uneven surface formed on at least one of the front and back surfaces of the polyliner W.
If the tip of the vibration sensor 11 contacts and causes vertical vibration, the polyliner W detects and determines that the front side is exposed, and if the tip of the vibration sensor 11 is in contact with a smooth surface. Since no vertical vibration occurs in the vibration sensor 11, it is determined that the back side is exposed.

Furthermore, FIGS. 6(a) and 6(b) show a method of determining the color of the polyliner W by the liner color determining device 13. In the embodiment of the present invention, two colors, yellow and white, are used. , and is configured to be discriminated by a color detection fiber sensor 23.

The liner check and drying device 8 is configured as described above, and the polyliner W has an uneven surface formed in advance on at least one of the front and back surfaces, and the front and back surfaces are formed in different colors. When the rolled up rolls 3 are conveyed one after another, the rolls 3 are gripped by the transfer device 5 and transferred to the liner check device 8 to a predetermined position X.

At this predetermined position X, a vibration sensor 11 is placed on the surface of the scroll 3 as shown in FIGS.
The scroll 3 is moved in the direction of the arrow shown in the figure while in contact with the scroll 3, the uneven surface of the scroll 3 is detected, and the front and back sides of the scroll 3 are determined. At the same time, the fiber sensor 23 for color detection, which is emitting light onto the surface of the scroll 3, is used as shown in Fig. 6 (
a) As shown in CD>, the color of the polyliner W exposed on the surface of the scroll 3 is determined.

Also, FIGS. 7(a), (b) and 8(a). (
b) shows a method for determining the winding direction of the scroll 3,
7(a) and (b) show the case of determining whether the polyliner W is wound to the left. The scroll 3 is rotated to the left to unwind the tip Wa of the polyliner W, and at this time, the tip Wa of the polyliner W is unwound. When the tip Wa of the hanging polyliner W is turned on by the reflective projector 25a for detecting left-handed winding, it is determined that the polyliner W is left-handed.

In addition, FIGS. 8(a) and 8(b) show the case where right-handed winding of the polyliner W is determined, and the scroll 3 is rotated to the left to unwind the tip Wa of the polyliner W, and at this time the scroll When the tip Wa of the polyliner W hanging from the polyliner W is turned ONL by the reflection type projector 25b for detecting right-handed winding, it is determined that the polyliner W is right-handed.

In addition, in both cases of right-hand winding and left-hand winding, the direction in which the tip Wa of the polyliner W is unwound is to the left, as shown in Fig. 7 (a), (out) and Fig. 8 (a), (b). In the case of Figures 8(a) and (b), the polyliner W is rotated in the direction in which it is unwound once, but when the tip Wa of the polyliner W exceeds the apex, it breaks apart and rotates in the direction shown in Figure 8(b). ).

Next, when the winding direction of the polyliner W is determined as described above, the end portion of the polyliner W must be rewound and stored in the polyliner supply center 4, which will be described later, in an aligned state. That is, when the roll organizing and storing mechanism 9 of the polyliner supply center 4 rotates, if the end portions of the polyliner W are not aligned, the end portions of the polyliner W may become entangled or caught, and the polyliner W The end portion of the scroll 3 is unwound, and this causes a problem in that the scroll 3 is stained or torn, causing problems when setting the scroll 3.

Therefore, after determining the winding direction of the polyliner W, it becomes necessary to control the end portion of the polyliner W to be constant.

For this reason, in the present invention, a method of controlling the end portion of the polyliner W to a constant value is used.Next, this method of controlling the end portion of the polyliner W to a constant value is described in FIGS. 9(a), (b) to 12(a). ),
This will be explained with reference to (b).

(a). In the case of a right-handed liner When the winding direction of the polyliner W is right-handed, the unwinding position of the polyliner W is as shown in FIG. 9(a), and the reference position of the winding shaft of the transfer device 5 is As P, as shown in FIG.
The polyliner W is rotated counterclockwise and rewound until b is in the OFF state. At this time, the reference position P of the winding shaft of the transfer device 5 has moved to the position P1,
The movement angle θ at this time is stored in a storage device (not shown) of the transfer device 5.

O)), In the case of a left-handed liner When the winding direction of the polyliner W is left-handed, the unwinding position of the polyliner W is as shown in FIG. Setting the reference position as P, as shown in FIG. 10(b), the polyliner W is rotated clockwise and rewound until the reflective projector 25a for left-hand winding detection is in the OFF state. At this time, the reference position P of the winding shaft of the transfer device 5 has moved to the position P1, and the movement angle θ (unwinding angle) at this time is
The information is stored in a storage device (not shown).

As described above, when setting the unwinding angle θ of a right-handed liner or a left-handed liner in a storage device and setting it at a predetermined position in the roll organizing and storage mechanism 9 of the polyliner supply center 4, the polyliner supply center The polyliner W was rewound by controlling the rotation of the winding shaft of the transfer device 5 by using the value stored in the storage device as it is or by using the calculated value according to the storage command from 4. The rolls are stored in a predetermined position in the roll organizing and storing mechanism 9 of the polyliner supply center 4 as they are.

For example, when storing the rewound roll 3 of polyliner W on the left outer side of the roll organizing and storing mechanism 9 of the polyliner supply center 4 as shown in FIG. 10(b), as shown in FIG. As shown in a), the reference position P provided on the left side is moved by an angle θ to the position in the clockwise direction Pi, and if the posture of the transfer device 5 is the same as the rewinding position and the storage position, it is stored as is. do.

Further, as shown in FIG. 9(b), when storing the rewound polyliner W roll 3 in the left inner side of the roll organizing and storing mechanism 9 of the polyliner supply center 4, the 11th
As shown in Figure (b), move the reference position P provided on the left side by an angle of 10 degrees to the position in the counterclockwise direction Pi, and if the posture of the transfer device 5 is the same as the rewinding position and the storage position, leave it as it is. Store it in this condition.

Next, when storing the roll 3 of the polyliner W in the right inner side of the roll organizing and storing mechanism 9 of the polyliner supply center 4, the reference position provided on the right side as shown in FIG. P is moved by an angle of 1θ in the counterclockwise direction to the position P1, and in this state, the reference position P2 is reversely moved by 180°.

Since the posture of the transfer device 5 is different between the rewinding position and the storage position (the reference position is shifted by 180 degrees), the reference position P2 is changed to 18
Flip it 0 degrees and store it so that it matches. In addition, when storing the roll 3 of the polyliner W on the right outer side of the roll organizing and storing mechanism 9 of the polyliner supply center 4, the reference position P provided on the right side is used as shown in FIG. 12(b). is moved by an angle θ to a position in the clockwise direction P1, and in this state, the reference position P2 is reversely moved by 180°.

Since the posture of the transfer device 5 is different between the rewinding position and the storage position (the reference position is shifted by 180 degrees), the reference position P2 is changed to 18
Flip it 0 degrees and store it in a matching state.

By controlling the end portion of the polyliner W in a constant manner as described above, automatic setting of the scroll 3 can be easily performed.
Moreover, it is possible to prevent the polyliner W from getting caught during handling.

Next, the roll organizing storage mechanism 9 of the polyliner supply center 4 and the reversing device 10 for correcting the winding direction of the polyliner W

Note that in the rotated state, the reversing tables 10a, 1. O
Since the pin b and the pin 27 are in a state facing each other, they are pushed into the bottle 27 as they are.

Then, a plurality of scrolls 3 with the same color and winding direction are arranged and stored in the set storage zones Sl and S2, and in this state, the front and back sides of the scrolls 3 are stored in storage devices (not shown) in the storage zones Sl and S2. By leaving the winding proboscis 3 (step ①), the winding proboscis 3 can be sequentially supplied in response to requests from the next process.
