As shown in FIGS. 2 to 4, the liner check device 8 installs a vibration sensor 11 on the surface of the polyliner W above the set position χ of the roll 3 transferred by the transfer device 5. A front and back surface detection device 12 detects the front and back surfaces of the scroll W by bringing their tips into contact and detecting the uneven surface formed on at least one of the front and back surfaces, and a front and back surface detection device 12 that detects the color of the front and back surfaces of the polyliner W. a liner color discrimination device l3 for discriminating the color exposed on the surface of the scroll 3, and the scroll W

In the front and back surface detection device 12, as shown in FIG. are doing. Also,
In the liner color discrimination device 13, a color detection fiber sensor 23 is attached to a guide frame 24 attached to the lifting frame 17, and this color detection fiber sensor 23 is always attached toward the surface of the roll 3.

Further, the liner winding direction detection device 15 that determines the winding direction of the scroll 3 includes a reflective projector 25a for detecting left-hand winding and a reflective projector 25b for detecting right-hand winding below the set position X of the scroll 3.
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 checking device 8 is shown in FIG. 5(a). (b) - Figure 8 (a) (b)
This will be explained with reference to.

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 1l in contact with the surface of the polyliner W. , and a vibration sensor l 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 1l, 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 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 is formed with different colors on the front and back surfaces, and the polyliner W is wound up. When the rolled rolls 3 are conveyed in sequence, the rolled 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 (
As shown in a) and (b), 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. It is determined that the polyliner W is left-handed when the tip Wa of the hanging polyliner W is turned on by the reflective projector 25a for detecting left-handed winding.

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 designed to determine that it is right-handed.

In addition, in both right-handed and left-handed cases, the direction in which the tip Wa of the polyliner W is unwound is as shown in Fig. 7 (a) and (b).
) and Figure 8(a). As shown in (b) D, it is rotated to the left, and in the case of Fig. 8 (a) and (b),
This is the direction in which the polyliner is rewound once, but when the tip Wa of the polyliner W exceeds the apex, it falls apart, resulting in a state as shown in FIG. 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 on the end portions of the polyliner W already in stock. 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, is it possible to control the end portion of the polyliner W to a constant value? The need for IU will arise.

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 shown in FIGS. ，
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. 9(b), a right-handed detection reflective type projector 25
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.

(b). 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. ,
As shown in FIG. 10(b), the polyliner W is rotated clockwise and rewound until the left-handed detection reflection type projector 25a 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 PL, and the movement angle θ (rewind angle) at this time is stored in the storage device (not shown) of the transfer device 5. Leave it alone.

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 P1, and since the posture of the transfer device 5 is the same as the rewinding position and the storage position, it is stored in that state.

In addition, as shown in Fig. 9 et al., the polyliner W is rewound.
When storing the scrolls 3 in the left inner side of the scroll organizing and storing mechanism 9 of the polyliner supply center 4, the reference position P provided on the left side is moved counterclockwise to P1 as shown in FIG. 11(b). The transfer device 5 is moved by an angle of 1.theta. to the position shown in FIG.

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 1θ to the position of P1 in the counterclockwise direction, 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.

In addition, when storing the roll 3 of the polyliner W on the outer right side of the roll storage mechanism 9 of the polyliner supply center 4, the reference position P provided on the right side is Move the angle θ to the position in the direction P1,
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 storing position (the reference position is shifted by 18o), 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
a, 10b will be explained with reference to FIGS. 1 and 13. First, the scroll organizing and storing mechanism 9 stores the scroll 3 of the yellow polyliner W in the frame 18 configured in a frame shape. It is divided into a first zone S1 and a second zone s2 in which a roll 3 of white polyliner W is stored, and sprockets 26a and 26b are arranged above and below in the first zone SL and the second zone S2, respectively. And each sprocket 26
Chains 28a and 28b each having a plurality of pins 27 attached at predetermined intervals on which the scroll 3 is hung are hung around a 26b,
An actuator (not shown) is connected to one of the sprockets 26a, 26b to rotate the chains 28a, 28b, respectively.

The reversing device 10 corrects the winding direction of the polyliner W.
a, 10b, on both sides of the frame 18 of the scroll organizing and storing mechanism 9, inverting tables 29a, 29b which can be rotated horizontally by 180 degrees via a drive motor (not shown) are installed. , a pin 30a for hanging the scroll 3
, 30b are provided.

Next, how to organize and store the scrolls 3 is shown in Figure 13 and Figure 1.
．． This will be explained with reference to FIG.

First, the rolls 3 that are randomly transported are checked by the liner checking device 8, which checks the front and back sides of the polyliner W.
After determining the color and winding direction (step ■), the polyliner supply center 4 is color-coded according to the color exposed on the surface of the roll 3, that is, the color (yellow, white) of the polyliner W (step ■). They are respectively transferred to at least two types of accommodation zones Sl and S2.

If the winding direction (step ■) of the polyliner W corresponds to the set winding direction (right-hand winding, left-hand winding, shown as right-hand winding in the embodiment of this invention), the yellow liner is directly storage zone S1 or white liner storage zone s
If the winding direction is reversed, place it on the rotatable reversing tables 29a and 29b of the reversing device 10a or lob (step ■).
) Rotate l80@ by the actuator to set the winding direction in a predetermined direction (step ■).

Note that in the rotated state, the pins of the inversion tables 10a and 10b and the pin 27 are in a state facing each other, so that the inversion tables 10a and 10b are pushed into the pin 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 31 and 32, 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 it for a while (step ①), the rolls 3 can be sequentially supplied in response to requests from the next process.

Next, the automatic liner changing device will be further explained with reference to FIG. 1. In the vicinity of the transfer device 5, there are:
A relay position device 32 is installed to temporarily hold the roll 3 taken out from the polyliner supply center 4 by the transfer device 5 in response to a request from a plurality of winders 31a, 3lb, which will be described later.

This relay position device 32 is provided with a pin 33 on a support base 34 for hooking the self of the scroll 3.

Further, numeral 35 transfers the scroll 3 set in the relay position device 32 to a predetermined winder 31a, 3lb, and removes the actual roll main body 3a wound up by the winder 31a, 3lb, and transfers it to a predetermined bin rack cart 2. This rehanging device 35 is movable for loading, and is movably placed along a guide rail 36. A support 39 with a pivotable arm 38 is mounted on the machine base 37. It is erected. The arm 38 is provided with a fork member 40 that can be inserted into the scroll 3. The fork member 40 holds the scroll 3 and connects the relay position device 32, winders 31a and 3lb,
It is configured to rotate between the bin rank truck 2 and the bin rank truck 2.

Further, when a predetermined roll 3 is taken out and supplied from the polyliner supply center 4 in response to a request from the winders 31a, 3lb, the roll 3 that satisfies the requirements of the winder 31a, 3lb is stored. For example, if the front and back sides of Polyliner W are reversed,
It is necessary to modify it so that it can meet the requirements of the winders 31a and 3lb.

A method of supplying the liner in such a case will now be described with reference to FIGS. 15(a) to (C) and FIGS. 16(a) to (d).

As described above, in the embodiment of the present invention, the surface of the polyliner W having an uneven surface is defined as the front surface Wx, and the smooth surface is defined as the back surface wy.

15(b) shows a state in which the scroll 3 is set on the winding shaft of the transfer device 5. Further, FIG. 15(C) shows the winding machine 31a,
It shows the state in which the polyliner W is set to 3lb.

When there is a request from the winding machine 31a or 3lb for the polyliner W with the front side Wx facing up, the roll 'jjyJ3 stored in the polyliner supply center 4 with the back side Wy exposed on the front side is As shown in FIG. 15(C), a plurality of guide rollers 41a, 4lb, 41c, 4 provided in the supply path from winding machine 3la to 3lb

Moreover, FIGS. 16(a) to 16(d) show a correction method when the winding direction of the polyliner W is different from the requirement of the winder 31a or 3lb. If a request is made from the winder 31a or 3lb for the winding vA3 stored in the center 4 with the back side Wy exposed on the front side, if the request is for the winding vA3 with the back side Wy exposed on the front side, the request is made as shown in FIG. From the state of (a), the reversing device 10
Use a or 10b to turn 180° and
The state shown in FIG. 16(b) is established, and in this state, the roll 3 is set on the winding shaft of the transfer device 5 as shown in FIG. 16(C).
