Abstract

PURPOSE:To wind all strings uniformly and tightly by forcibly rotating a partition board through an outercircumferential drive belt to transmit rotary force to a winding board and rotating a winding board having small winding diameter while slipping the rotation of winding board having large winding diameter. CONSTITUTION:Plural friction boards 24 are secured to the outercircumference of a sleeve 23 fixed to main winding shaft 6 then a partition board 8 and a winding board 7 are arranged while pressure contacting between said boards 24 to couple a pair of partition board 8 and winding board 7 respectively. Wide drive belt 26 at the outercircumference of the partition board 8 is rotated to apply rotary torque onto the partition board 8. When winding the coil 5 continuously, the winding diameter of the central winding board 7 will increase to produce winding tensile force while the winding diameter will decrease toward the opposite sides to cause loosening. Here, the pressurizing bolts 48, 48 are operated to pressure contact the machining pulley 25 against the partition board 8 through the belt 26 where said belt 26 is rotated with higher speed than the circumferential speed of the partition board 8 to slide the tight central partition board 8 and to wind all strings uniformly and tightly.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) This invention cuts a wide original coil into a plurality of narrow product coils, and simultaneously cuts the coils into a uniform diameter k.

Moreover, it belongs to the technical field of tight winding methods and devices. Providing the product coil to demand while it is still softly wound will cause it to come loose.
This is a major inconvenience when transporting, storing, and disposing it in the next process.
The purpose is to wind multiple threads simultaneously and evenly and tightly.

(Prior Art) A series of conventional devices for passing an original coil through a slitter and winding it into a product coil are shown in FIGS. 14 and 15. That is, the original coil 2 placed on the uncoiler 1 is wound and uncoiled, passed through the slitter main body 8, and cut into a plurality of strips by the round blade cutter 4. The cut product coil 5 is wound around the winding plate 7 as a core while being restrained by the winding plate 7 and partition plate 8 fixed to the winding main shaft 6. After passing through the slitter main body 8, both sides of the original coil 20 are sent to the winder 1 as scrap 9.9.
It is wound up to 0.10.

In this way, in the conventional winding device, the partition plate 8 and the winding plate 7 are alternately fixed to the winding main shaft 6, so that both always rotate together with the winding main shaft 6 in the same direction and at the same speed. The winding plate 7 merely functions as the core of the product coil 5, and the partition plate 8 merely functions as a partition wall to keep the winding width constant. on the other hand,
The thickness of the original coil 2 is thick at the center portion 11 as shown in FIG. 16 due to the rolling process, and becomes thinner toward both side portions 12 and 13. Therefore, when this is cut by the slitter main body 8 and the individual product coils are wound around the winding plate 7, as each coil becomes thicker,
The product coil 5 of the central part 11 which is gradually thicker has both side parts 12 ,
It is wound up faster than the thin product coil 5 of 13, and its winding diameter is larger. Therefore, the product coil 5 on the center winding plate 7 is pulled and wound tightly, but as the product coils 5 on both sides of the product coil 5 are stretched, slack 14 is generated as shown in FIG. , it hangs down to the floor surface and comes into contact with it, causing damage to the product coil 5 and causing inconvenience as a product.

Conventionally, in order to prevent such slackening 14 of the product coil 5,
As shown in FIG. 17, when winding the product coil 5, a paper tape 15 was inserted between the product coils 5 each time, and the paper tape 15 was wound together with the product coil 5 on the winding plate 7 to overcome an emergency situation. However, inserting the paper tape 15 takes extra time and effort, and the paper tape 15 itself contains moisture, which causes rust on the product coil 5. In addition, the user has to use a separate unwinding machine to harden each strip one by one. The process of re-rolling was required and was complicated. In addition, after winding in the conventional loose state, the product coil 5 is cut from the original coil 2,
In some cases, one end of the product coil 5 is fixed to the machine and winding is performed one by one with the product coil 5 attached to the winding spindle 6, but in this case, the product coils 5 rub against each other and the winding tightens. There was a risk that smudge would stick to the surface.

(Problems to be Solved by the Invention) As mentioned above, in the conventional winding device for the slitter line, the winding hardness is uneven due to the simultaneous winding of the -axis. As shown in FIG. 18, there is a method in which a priddle roll 17 equipped with a brake and a tension pad device 18 are arranged in front of a winding device 16, and each strip is played during play to tightly wind it. However, in this method, if a slack 14 is formed in the strip, it is necessary to dig out a corresponding bit 19 to absorb it, and in addition, the photocell is It is also necessary to provide a device 2 to prevent this. Furthermore, as shown in Figure 19, there is also a single-shaft, single-thread winding device n.In this case, it is fine for winding up to a few threads, but when it comes to winding up to about I thread as in this line, this device is unable to do so. The installation area is large and the cost is also high.

In order to correct the drawbacks of the conventional slitter line as described above, a large-scale table device is required and the cost is extremely high. Therefore, in the present invention, the winding plate 7, partition plate 8, etc. of the conventional slitter line are devised. However, it is possible to wind the entire number of threads evenly using a simple and inexpensive device similar to the conventional one.

(Means for Solving the Problems) In view of the above-mentioned drawbacks of the conventional art, the present invention adopts the following technical means to meet the purpose. This is shown in Figure 9.

That is, in the first invention of the present application, when the product coil 5, which is obtained by cutting the original coil 2 into multiple strips by the slitter main body 8, is simultaneously wound by a plurality of winding plates 7, the outer periphery of the partition plate 8 is forcibly cut. While rotating the winding plate 7 to transmit its rotational force to the winding plate 7, and slipping the rotation of the winding plate 7, which increases the winding diameter, the winding plate 7, which has a small winding diameter, is rotated and wound. The product is characterized by a uniform coil winding method.

Further, the second invention of the present application is an apparatus that specifically implements the invention of the first method. That is, a plurality of friction plates are fixed to the outer periphery of the sleeve B fixed to the winding main shaft 6, and the partition plate 8 and the winding plate 7 are interposed by pressure between the friction plates, and the partition plate 8 and A product coil characterized in that a pair of winding plates 7 are connected to each other, and a wide drive bell 2B having a pressure pulley 5 on a part of the outer periphery of the partition plate 8 is pressed into contact with the product coil. To provide an even winding device. As shown in FIGS. 2 and 8, the sleeve n has a stopper n fixed to one end of the cylindrical body, a threaded portion 4 at the other end, and key grooves 29 and 30 carved on the inner and outer surfaces. This is what I did. As shown in FIGS. 4 and 5, the friction plate has a hole 31 drilled in the center of the disk and a key 32 that protrudes into the hole 31.The hole 31 is connected to the sleeve. When inserted into the sleeve B, the key 32 matches the key blanking and is fixed to the sleeve B. In addition, as shown in FIGS. 6 and 7, the partition plate 8 is a circular plate with a hole in the center, the outer circumference of which is rounded, and a reinforcing plate is provided on the side of the hole. M
A pin part 35 is provided in close contact with one direction, and when the hole (sleeve 23)'C is inserted, the small hole 3 of the winding plate 7
6 and 36, forming a pair. The winding plate 7 is also a circular plate with a hole drilled in the center, and the pin portion of the partition plate 8, 35
A small hole (A, 36) matching the above is bored, and a groove (A, 38) is carved on the circumferential surface.

By the way, if holes 39 and 39 are made on this disk surface,
Helps reduce weight.

In the present invention, first, the friction plate is inserted into the sleeve B, and then the partition plate 8, the friction plate M, the winding plate 7, the friction plate 8, the partition plate 8, and the friction plate U are repeatedly inserted into the sleeve B, respectively. , and the pins 35 of the partition plate 8 are aligned with the small holes 36 of the winding plate 7, and then several disc springs 41, 41 are connected via the holding ring 40 depending on the degree of tightness of the winding.
, and screw the nut 42 into the threaded part. Therefore,
Due to the elasticity of the disc spring 41 and the tightening of the nut 42, all of the above-mentioned parts, together with the stopper on the sleeve n, are closely interposed between the presser rings 40. At this time, the friction plate 2 is fixed to the sleeve O because its key 32 matches the keyway I of the sleeve O, but the partition plate 8 and the winding plate 7 are penetrated by the sleeve O. However,
It is not fixed, but is sandwiched between the friction plates 24 by pressure contact. The required number of friction plates is provided as appropriate to suit the width of the product coil 50. As can be seen in each figure, the diameter of these parts is that the partition plate 8 is the thickest (the friction plate is the smallest, and the winding plate 7 is medium in diameter.
, 37 are the same. In this way, the winding main shaft 6 is passed through the center of the through hole of the sleeve B in which each part is assembled into the sleeve B, and the key is aligned with the key in the sleeve B, and the protruding end 44 of the winding main shaft 6 is connected to the collar. 45
is fixed to form a winding device 46.

On the other hand, one wide drive belt 26 is brought into contact with the outer periphery of each partition plate 8 from the direction opposite to the direction in which the product coil 5 is inserted. As shown in FIGS. 1 and 10, this contact is made within a range of approximately 20 degrees from the outer circumference L of each partition plate 8.
Two pressurizing booms IJ-25, 25, which move in a cursor shape from the center, are pressed against the inner side of the winding device 47, which is in contact with the winding device 47.

The present invention consists of a mechanical connection between the winding device 46 and this winding device.

＼＼、U (Operation) According to the present invention, the product coil 5 obtained by cutting the original coil 2 into a plurality of narrow strips by the slitter main body 8 is formed between the kerfs of each winding plate 7 at the ends thereof. Insert and lock.

At this time, when the partition plate 8 is turned several times, the winding plate 7 also rotates.
The product coil 5 is tightly wound around the winding plate 7. in fact,
This operation is performed sequentially each time the winding plate 7 is inserted into the sleeve B. and wide drive bell) 2
6 to apply rotational torque to the partition plate 8. At the beginning of winding, if the entire winding force is [100, J], the winding device 46
Start winding with a winding force of about 40. At this time, the wide drive bell 26 rotates nine times without being in pressure contact with the partition plate 8. When winding is started, the wide drive bell 26 is also rotated at the same speed as the outer circumferential speed of the partition plate 8. As the product is wound over time, the winding diameter of the central winding plate 7 rapidly increases, and the product coil 5 between the winding plate 7 and the slitter main body 8 is stretched, creating winding tension. Further, the winding diameter of the winding plate 7 becomes smaller toward both sides, and slack 14 appears in the product coil 5 between the slitter main bodies 8. This is because the original coil 2 is rolled so that the center part 11 is thicker and the side parts 12 and 13 are thinner as shown in FIG. When the rotation speed of the wide drive belt 50 is slightly faster than the peripheral speed of the partition plate 8, the pressure pulley 5 is pressed against the partition plate 8 via the wide drive belt 26 by operating the pressure bolts 48 and 48. The partition plate 8 of the winding plate 7 with more slack 14 is rotated faster than the partition plate with less slack 14, and at the same time the partition plate 8 of the winding plate 7 with more slack 14 is rotated.
While slipping the product coil 5, the product coil 5 is wound up faster (winding) toward the side parts 12 and 13 than that of the central part 11, absorbing the slack 14, making the total number of threads equal, and making it possible to wind tightly. The reason for this is that the rotation of the wide drive belt is faster due to the rotation of the winding main shaft 6, and although the partition plate 8 and the winding plate 7 are interlocked, both are fixed to the winding main shaft 6 and the sleeve device. The friction plate acts like a clutch, and when the product coil 5 between the slitter main body 8 and the winding plate 7 is slack, it is wound by the slack 14. It is supplied to the removal plate 7, and
When the product coil 5 is stretched, the product fill is not supplied to the winding plate 7. Therefore, when the product coil 5 is slack, no slip occurs between the partition plate 8 and the wide drive bell 26, whereas when the product coil 5 is stretched, slip occurs. The degree of this slip is determined by the number of disc springs 41 tightened ffK, which determines the pressing force of the friction plates, which affects the stiffness when the product coil 5 is wound around the winding plate 7.

When the wide drive bell) 26 works in this way, the winding tension at the winding device 47km produces a force of ``ω'', so
When combined with the winding tension provided by the winding device 46, uniform winding can be achieved with a tension of 100J.

(Example) FIGS. 10 to 13 show specific examples of the present invention. Note that the symbols 1 to 48 \ to -1 have the same structure and operation as described above, so their explanation will be omitted.

The winding device 47 guides a slide main body 51 on a main body bed 49 by a slide give gloss, attaches a percentage motor 52 to the upper part of the slide main body 51 via a continuously variable speed motor, and transfers the driving force of the motor 52 to a V-belt. V via 68
The signal is transmitted to the pulleys 53 and 54, and the wide drive belt is rotated by the one-way clutch and the drive pulley.

When the winding main shaft 6 initially starts winding with the "off" force, the one-way clutch 55 presses the wide drive bell (26) of the winding device 47 against the partition plate 8 and rotates it 9 times to turn the motor. It functions so that no strain is added to the 52. Further, this regular winding device 47 has the function of moving the slide main body 51 rearward using the attachment/detachment handle 57 to take out the product coil 5 when performing tight winding and after the completion of tight winding. In addition, in order to press the wide drive bell (26) against the partition plate 8 with the attachment/detachment handle 57, the attachment/detachment handle 57
If you tilt it to the left, force will be transmitted to the bracket 62 through the lever group, bottle 59, link mark, and slide adjustment handle 61, and the belt frame 68 will move forward, causing the wide drive bell) 2
6 contacts the partition plate 8. When the motor 52 rotates, the wide drive belt rotates, and the partition plate 8 rotates. The degree to which the wide drive bell (26) is pressed against the partition plate 8 is controlled by the slide adjustment handle 61. If slack 14 occurs due to some inconvenience among the total multipliers, apply the auxiliary pressure welding device to the partition plate 8 in that part, turn the adjustment screw 65, and tighten the roller 66 to the wide drive belt. The slack 14 is adjusted by applying pressure and winding the threads faster than other thread numbers. Therefore, this roller 66 has a narrow width, so that the pressing force against each partition plate 8 can be adjusted. In addition, the code 67ft and the tension pulley are:
This is to adjust the tension of the wide drive belt.

(Effects of the Invention) According to the present invention, the winding device winds the winding plate with a force of “Tochi” so that each winding plate can slip, and the winding device applies a force of “60” to the outside of the partition plate. The winding plate is rotated and this force is transmitted to the winding plate so that each one slips appropriately and a total of 1
Since it is wound with a force of 0.00 J, slack can be easily absorbed. In addition, since the outer periphery of the partition plate with the largest diameter is rotated, similar to the principle of leverage and torque, a large force can be transmitted to the winding plate with a small force, which is extremely rational.

Furthermore, the wide drive belt is not limited by the product width, and is particularly effective for winding up narrow products. The wide drive belt is in pressure contact with the outer periphery of the partition plate so as to wrap it over a range of 120 degrees (+), so even if the partition plate is thin, it can transmit a large rotational force. Furthermore, since the operation is simple and the winding is sufficient, there is no need for the complicated process of inserting paper tape and winding it, and there is no need for the winding process of the product coil, so there is no need for time-consuming defects on the product coil. does not occur. In addition, there is no need for bits, plies)/L/a-rules, tension pad devices, etc., contributing to lower costs.
It can be incorporated into conventional slitter lines.
