Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for controlling the end of a liner at a constant level, and more specifically, by controlling the end of a polyliner stored in a polyliner supply center at a constant level, The present invention relates to a liner terminal constant control method that facilitates automatic centing of scrolls.

[Prior Art] Conventionally, in a winding device that winds a strip material such as an unvulcanized comb sheet into cells, a thin polyethylene sheet called a polyliner is used to prevent the strip materials from coming into close contact with each other. The material is wound up while being interposed between the strips of material.

By the way, conventionally, when rehanging a roll of polyliner to a winding machine, the terminal part of the polyliner is adjusted to a certain level and then rehanging is set on the winding machine, and the strip material and polyliner are removed from the winding machine. They were removing small rolls of wood and loading them onto a trolley.

[Problem that the invention seeks to solve]

However, when automatically rehanging the poly liner, the ends of the poly liner must be aligned in a constant manner, which requires a lot of effort and time, and reduces the ability to cast rolls. Furthermore, there was a problem in that a great deal of labor was required to rehang the scrolls, which placed a heavy burden on the operator.

[Purpose of the invention]

This invention was devised by focusing on the conventional problem, and when storing the rolls in a predetermined position of the roll organizing and storing mechanism of the polyliner supply center, the end portions are stored in a constant state, and the rolls are stored in a fixed position. To provide a constant control method for a liner end, which can automatically and reliably supply a liner according to a request from a take-up machine, improve the productivity of rolls, and further reduce the labor of an operator. The purpose is to

[Means for Solving the Problems] In order to achieve the above object, the present invention uses an angle storage device provided in a transfer device and an optical detection means of a liner tick device for detecting the end portion of a polyliner. Detecting the unwinding position of the polyliner, storing the value in the storage device, storing the roll in a predetermined position of the roll organizing and storing mechanism of the polyliner supply center with the polyliner unwinding, The gist of this is that it can be automatically supplied in response to requests from the winding machine.

[Action of the invention]

This invention is constructed as described above, and the transfer device transfers and sets the roll to the roll setting position where the liner linking device is installed, and in this state, the polyliner unwound from the roll is transferred. The winding shaft of the loading device is used to rewind the liner ticking device until the liner winding direction side light of the left-hand winding detection reflection type illuminator and the right-hand winding detection reflection type phototube of the optical detection means of the liner ticking device passes through. At this time, the movement angle of the winding shaft from the unwinding start reference position to the position after unwinding is stored in a storage device installed in the transfer device, and the movement angle is stored in the storage device in response to a storage command from the polyliner supply center. By using the value as it is or using the value that has been processed, the rotation of the winding shaft of the transfer device can be controlled, and the rolls can be organized and stored at the polyliner supply center while the polyliner remains rewound. It is characterized by being housed in a predetermined position of the mechanism.

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.

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 in FIGS. 5(a), (b) to 8(a), (b).
).

First, FIGS. 5(a) and 5(b) show 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 l on the uneven surface formed on at least one of the front and back surfaces of the polyliner W.
When the tip of the vibration sensor 1 contacts and causes vertical vibration, the polyliner W detects and determines that the surface side is exposed, and when the tip of the vibration sensor 1l 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 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 30 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 (b), the color of the polyliner W exposed on the surface of the scroll 3 is determined.

In addition, Fig. 7(a), (b) and Fig. 8(a), (
b) shows a method for determining the winding direction of the scroll 3,
FIGS. 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 cases of right-hand winding and left-hand winding, the direction in which the tip Wa of the polyliner W is unwound is as shown in FIG. 7(a). (b
) and as shown in FIGS. 8(a) and (b), it is rotated to the left, and as shown in FIG. 8(a). (In the case of bj,
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 W0) is unwound, and
They must be 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 with or caught on the end portions of the polyliner W that have already been stretched. 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 a certain degree.

For this reason, in the present invention, a method of controlling the end portion of the polyliner W to a constant value is used.
1k[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 As shown in FIG. 9 (bl), the reference position of
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 50 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 the state shown in No. 10II (a), where the reference position of the winding shaft of the transfer device 5 is P, As shown in FIG. 10(b), the polyliner W is rotated clockwise until it is rewound until the reflective light projection B 25a for left-hand winding detection is turned off. 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 stored in the storage device (not shown) of the transfer device 5. I'll keep it in mind.

As described above, when the unwinding angle θ of a right-handed liner or a left-handed liner is stored in the storage device and the roll storage mechanism 9 of the polyliner supply center 4 is placed at a predetermined position, the polyliner supply center By using the value stored in the storage bag holder according to the storage command from 4 or using the calculated value, the rotation of the winding shaft of the transfer device 5 is controlled and the polyliner W is rewound. The rolls are stored in a predetermined position in the roll organizing and storing mechanism 9 of the polyliner supply center 4 while remaining in the same state.

For example, when storing the rewound roll 3 of polyliner W on the left outer side of the roll storage mechanism 9 of the polyliner supply center 4 as shown in FIG. As shown in a), move the reference position P provided on the left side by an angle θ to the position in the clockwise direction P1, 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 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 10 degrees to the position PI in the counterclockwise direction. 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 1.theta. 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 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
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 the roll 3 of white Bolliner W is stored, and the first zone S1 and the second zone S2 have upper and lower sprockets 26a. 26b are arranged respectively, and each sprocket 26
Chains 28a and 28b, each having a plurality of pins 27 on which the scroll 3 is attached with predetermined spacing, are hung around a and 26b, and an actuator (not shown) is connected to one of the subrokets 26a and 26b. 28b are each rotated.

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 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 FIG.

First, the rolls 3 that are randomly conveyed are transferred to the front and back sides of the polyliner W using the liner chenok device 8 mentioned above.
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 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 light is directly Storage zone SL for Yo- or storage zone S for white liner
If the winding direction is reversed, place it on the rotatable reversing tables 29a, 29b of the reversing device 10a or 10b (step ■).
) Rotate 180° using the actuator to set the winding direction to the specified direction (Step ■).

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 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 it for a while (Stenob ■), the rolls 3 can be sequentially supplied in response to requests from the next process.
