[Embodiments of the invention]

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

FIG. 1 shows a schematic layout diagram of an automatic liner changing device according to the present invention. A rotatable transfer device 5 (robot) is installed to transfer the rolls 3 to the polyliner supply center 4 side.

The pin rack truck transport device 1 has the pin rack truck 2 movably placed on a guide rail 6, and the fork 2a of the pin rack truck 2 is wrapped with the polyliner W described above. A plurality of roll-shaped scrolls 3 (in this embodiment, two scrolls 3 on one fork 2a) are hung and transported.

The polyliner supply center 4 has a
As shown in the figure, the front and back surfaces of the polyliner W (in the embodiment of this invention, the surface with the uneven surface is the front surface and the smooth surface is the back surface), the color of the polyliner W (
In the embodiment of this invention, yellow and white) and winding direction (right-handed,

10b is provided.

As shown in FIGS. 2 to 4, the liner check device 8 installs a vibration sensor 1l on the surface of the polyliner W above the set position X 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 13 that discriminates the color exposed on the surface of the scroll 3; and a liner color discrimination device 13 that discriminates the color exposed on the surface of the scroll W;
A liner winding unit is installed below the sesoto position It is composed of a direction detection device 15.

The front and back surface detection device 12 and the liner color discrimination device 13
is attached to an elevating frame 17 equipped with a plurality of rotatable guide rollers 16, as shown in FIGS. 3 and 4, and this elevating frame 17 is attached to the frame l8 of the polyliner supply center 4. fixed frame l9
, a vertically slidable guide rod 20a. 20b
The guide rods 20a and 20b are equipped with coil springs 2l that absorb vibrations in the vertical direction.
is interposed.

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.
are disposed and the reflective projectors 25a. 25b is activated to determine whether the polyliner W is wound to the right or left.

Next, a specific check j-7 is performed using the liner check device 8.
The evening method is shown in Figures 5(a), (b) to 8(a), (
This will be explained with reference to b).

First, FIGS. 5(a) and 5(b) show the front and back surface detection device l2.
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 l1 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 l1, it is determined that the back side is exposed.

Furthermore, FIGS. 6(a) and 6(b) show a method for 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.

Then, at this predetermined position
1 in contact with the scroll 3 in the direction of the arrow shown in the figure, 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, as shown in FIGS. 6(a) and 6(b), the color detection fiber sensor 23, which is emitting light onto the surface of the scroll 3, detects the polygons exposed on the surface of the scroll 3. Determine the color of liner W.

In addition, Fig. 7(a), (b) and Fig. 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.

Also, FIG. 8(a). (b) is a case in which right-handed winding of the polyliner W is determined, and the roll 3 is rotated to the left to unwind the tip Wa of the polyliner W, and at this time, the polyliner W hanging from the roll 3 is When the reflective projector 25b whose tip Wa detects right-hand rotation is ONL, 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 as shown in Figures 8(a) and (b), it is rotated to the left, and in the case of Figures 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. A problem arises in that the end portion of the scroll 3 is unwound, and as a result, the end portion of the scroll 3 may be stained or torn, which may cause problems when the scroll 3 is being cented.

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 the state shown in FIG. 9(a), and the winding axis of the transfer device 5 is Assuming that the reference position is 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 PI,
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-hand winding 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 P1, and the movement angle θ (rewind angle) at this time is stored in the storage device (not shown) of the transfer device 5. I'll leave it to you.

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. In this state, it is stored in a predetermined position next to the roll organizing and storing machine 9 of the polyliner supply center 4.

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 if the orientation of the transfer device 5 is the same as the rewinding position and the storage position, it is stored as is. do.

In addition, as shown in FIG. 9(b), when storing the rewound roll 3 of the polyliner W 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 1θ to the position in the counterclockwise direction Pl, 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 rolls 3 of the polyliner W on the inside right side of the roll storage mechanism 9 of the polyliner supply center 4, as shown in FIG. The position P is moved by an angle of 1θ to the position in the counterclockwise 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
0" and store it in a state where it is inverted and matched.

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 storing position (the reference position is shifted by 180''), the reference position P2 is changed to 1.
Flip it 80 degrees and store it upside down.

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 horizontal scroll organizing and storing machine 9 stores the scrolls 3 of yellow polyliner W in the frame 18 configured in a frame shape. The first zone S1 is divided into a first zone S1 where the roll 3 of the white polyliner W is stored, and a second zone S2 where the roll 3 of the white polyliner W is stored. Set up each sprocket 2
6 a, 2'. Chains 28a, 28 with pins 27 for hanging the scroll 3 attached at predetermined intervals to 6b.
chain 28a by connecting an actuator (not shown) to one of the sprockets 26a and 26b.
, 28b are each rotated.

The reversing device 10 corrects the winding direction of the polyliner W.
a. 10b is provided on both sides of the frame 18 of the scroll organizing and storing mechanism 9, and is provided with inversion tables 29a. 29b is installed, and on these reversing tables 29a, 29b, there is a bin 30a for hanging the scroll 3.
30b is 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 Figure 4.

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 of the polyliner W (yellow, white) (step ■). They are each transferred to at least two types of storage zones St, 32.

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 containment zone SL or white liner containment zone S
If the winding direction is reversed, the rotatable reversing table 29a. Place it on 29b (stesobu■
) It is rotated by 180° using the actuator to set the winding direction to a predetermined direction (step ①).

Note that in the rotated state, the pins of the inversion table 10a10b and the pins 27 are in a state facing each other, so that the inversion table 10a10b is pushed into the pins 27 as is.

Then, a plurality of scrolls 3 with the same colors and winding directions are arranged and housed in the set storage zones S1 and S2, and in this state, the front and back sides of the scrolls 3 are placed in the storage zone S1. By storing the information in the undisclosed storage device of S2 (Stenob 3), the scrolls 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, which temporarily holds 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 winding machines 31a23lb, which will be described later.

This relay position device 32 is provided with a bin 33 on a support base 34 for hooking the cells 7 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 scroll body 3a wound up by the winder 31a, 3lb, and transfers it to a predetermined pin rack cart 2. This rehanging device 35 is movable for loading, and is movably mounted along a guide rail 36, and a support 39 with a pivotable arm 38 is erected on a machine stand 37. It is set up. The arm 38 is provided with a fork member 40 that can be inserted into the roll 3. The fork member 40 holds the roll 3 and connects the relay position device 32 and the winder 31a. 31b and
It is configured to rotate between it and the pinranok 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 demands of the winders 31a, 3lb is stored. For example, if the front and back sides of Polyliner W are reversed, it is fine.
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.
