Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for supplying paper strips for winding and tightening adjustment of slit coils. This invention relates to a slit coil winding adjustment paper strip feeding device capable of appropriately feeding paper strips into the coils in order to tightly wind each slit coil when winding them to form the same number of slit coils.

[Conventional technology]

When a metal strip such as a steel strip is slit into a plurality of metal strips, the amount of elongation of each strip often differs. Therefore, when these metal strips are wound by one recoiler drum, the winding tightness of each slit coil differs, and the outer diameter also differs. As the winding thickness of the coil increases, the difference becomes larger.As a result, when a slit coil that is not tightly wound is removed from the recoiler drum, the coil, which should maintain a cylindrical shape, becomes flat. transform. When such a coil is processed for a different purpose, it may become impossible to insert it into the uncoiler drum used, or it may become plastically deformed in places where it is severely deformed, making it impossible to use it for processing into secondary products. Sometimes.

Conventionally, the following solutions have been adopted to prevent such insufficiently tightened coils.
A looping pit is provided between the slitter stand and the recoiler to loop the slitted metal strip, absorbing the difference in winding length between the slit coils, and allowing the operator to adjust the slit coil as needed during winding. For example, a piece of paper such as a strip of cardboard is inserted into the coil. In the former case, space and a looper are required, which increases equipment costs, and if the metal strip is thick, there are drawbacks such as the inability to loop it. On the other hand, when a pull-cut method is adopted to obtain the necessary tension, a looper is often not provided, so the latter method is often adopted. In this case, at least two workers are placed close to the side of the recoiler drum on the left and right, and while observing the looseness of the moving metal strip and the tightness of the slit coil, The work involves inserting a piece of paper into the winding position of the slit coil. This process has the advantage of being simple and easily achieving the desired results.

[The problem that the idea aims to solve]

The above-mentioned paper strip insertion operation is performed in a small gap between a number of metal strips moving in parallel and the winding position of each slit coil. Since this is a manual process, there are several problems in terms of workability and safety. Including the person who inserts the paper strips and the person who operates the device, at least three workers are required at all times.
Labor saving is strongly desired.

By the way, Japanese Unexamined Patent Publication No. 53-3947 describes a device for mechanically inserting a cushioning cardboard sheet when winding a slit coil. According to this device, the stacked cardboard sheets can be taken out one by one using a spike roller or the like as necessary, placed on a sliding table or guide plate, and sent out at the winding position of the slit coil. However, since the cardboard sheet moves under its own weight, it has the disadvantage that it may change its position diagonally during delivery or may not be able to be fed to the winding position at a desired timing.

On the other hand, Japanese Utility Model Application Publication No. 56-36660 proposes a device in which a cardboard sheet is brought into contact with the back surface of a metal strip just before the winding position and can be guided to the winding position. In this device, unless the winding thickness of the slit coil is detected and the winding position is confirmed, the cardboard sheet on the free conveyor cannot be brought into reliable contact with the metal strip. For this purpose, a proximity switch is attached to the tip of the free conveyor facing the winding position to detect the position of the surface of the wound slit coil. In addition, a belt conveyor is used to supply the cardboard sheets from the case storing the cardboard sheets to the free conveyor, and the free conveyor is attached to the tip of the movable frame bent from the upper end of the belt conveyor. Because of this, there are the following difficulties.

First, since the proximity switch is always in contact with the surface of the slit coil, the detection part is worn out by the slit coil being wound, and cannot withstand long-term operation. On the other hand, since the cardboard sheet is conveyed by a belt conveyor, the movement of the cardboard sheet is not necessarily guaranteed, as in the case described in the above-mentioned publication. That is, the sheet may change its position during movement, causing the sheet to be biased within the wound slit coil, or a portion of the sheet may protrude from the end surface of the coil. In addition, since the belt conveyor and free conveyor are fixedly attached to a single movable frame bent in a dogleg shape, the relative installation angle of both conveyors is constant, and the amount of roll thickening can be adjusted. When the angle of the movable frame is changed accordingly, the entire surface of the cardboard sheet on the free conveyor does not necessarily come into uniform contact with the moving metal strip, and the position at which the cardboard sheet is rolled in is moved by the frictional force with the metal strip. supply will not be ensured.

The present invention was developed to solve the above-mentioned problems, and its purpose is to remotely and automatically insert paper strips into the slit coil being wound, thereby avoiding the need for an operator to insert the paper strip into the slit coil being wound. It is possible to reliably feed the slit coil at the desired timing while maintaining the orientation of the winding adjustment paper to the slit coil being removed, and a non-contact detection device is used to detect the amount of winding thickness of the slit coil, ensuring stable operation over a long period of time. It is an object of the present invention to provide a feeding device for adjusting paper strips for winding and tightening a slit coil.

[Means to solve the problem]

As shown in FIG. 1, the slit coil winding adjustment paper strip supply device of the present invention supplies the winding adjustment paper strip 4 to the metal strip 3 being wound by the recoiler drum 2.
The present invention is applied to a paper strip supply device 1 that is capable of feeding paper strips 4 to a winding position while detecting the amount of winding thickening of paper strips b. Its features are as follows.

The first moving means 13 moves the paper strip supply means 5 in the axial direction of the recoiler drum 2 by the rotation of the threaded rod 13a, and the paper strip supply means 5 is moved to the winding position of the slit coils 3a, 3a, etc. by the rotation of the threaded rod 14a. To move to 3B (see Figure 3),
Second moving means 14 that raises and lowers the first moving means 13
is provided. And the first moving means 13
The paper strip supply means 5 attached to the paper strip supply means 5 includes an extruder 11 that pushes out the paper strips 4 in the storage case 8 that accommodates the rolled-up adjustment paper strips 4 in a stacked manner in the paper strip supply direction.
and a supply roll 12 that feeds the extruded tightening adjustment paper piece to the winding position 3B of the slit coils 3a, 3b, . . . while sandwiching the sheet. In addition, the wound slit coil 3a,
A non-contact type winding thickening amount detection sensor 17 that detects the distance from the surface of the slit coils 3a, 3b... is held at a constant distance from the surface of the slit coils 3a, 3b... by the sensor displacement motor 18, and the second moving means 14
is provided with a roll thickening following motor 19 that is driven in conjunction with the sensor displacement motor 18 in order to cause the paper strip supply means 5 to face the winding position 3B.

[Function] The metal strip 3 forms several slit coils 3a, 3b.
While being rolled up as..., they all thicken in almost the same way. The coil surface position at that time is detected by the winding thickening amount detection sensor 17. The winding thickening amount detection sensor 17 instructs the sensor displacement motor 18 to be driven so as to maintain a substantially constant distance from the coil surface position, and sequentially moves upward in the radial direction of the recoiler drum 2. Along with this movement, the first moving means 13 to which the paper strip supply means 5 is attached is moved by the winding thickening following motor 19, and the delivery position of the winding adjustment paper strip 4 of the paper strip supply means 5 is adjusted to the slit coils 3a, 3b. It is adjusted so that it faces each winding position 3B of....

As the recoiler drum 2 rotates, if any of the metal strips 3 becomes loose, the winding tightness of the slit coil 3b becomes weaker. The first moving means 13 moves the paper supply means 5 in the axial direction of the recoiler drum 2 so that the paper supply means 5 faces the winding position 3B of the metal strip 3.

The extruder 11 in the storage case 8 is driven and the supply roll 12 is rotated. The pushed out piece of paper 4 is sent to the winding position 3B while being held between the supply rolls 12.

[Effect of idea]

According to the present invention, in order to make all the slit coils wound around one recoiler drum tight, it is possible to remotely supply winding adjustment paper strips to desired slit coils at any time. Then, the winding adjustment paper strips are supplied to the slit coils accurately and quickly at the desired timing while maintaining the same position, and the winding adjustment is performed almost equally on all slit coils, thereby maintaining the quality of the coils. can be held. Furthermore, the amount of winding thickening of the slit coil can be detected without employing a device that comes into contact with the coil, and stable operation with little trouble can be maintained over a long period of time.

〔Example〕

Hereinafter, the present invention will be described in detail based on examples thereof. FIG. 1 shows an embodiment of the slit coil winding adjustment paper strip supply device 1 of the present invention, in which the winding adjustment paper strip 4 is supplied to the metal strip 3 being wound by the recoiler drum 2.
While detecting the amount of roll thickness of a, 3b..., paper strip 4
It is designed so that it can be rolled up and sent out to the position. That is, several slit coils 3a, 3b wound on the recoiler drum 2
One of them is a paper strip supply means 5 for supplying the winding adjustment adjustment paper strip 4, a moving body 6 for moving this paper strip supply means 5, and a recoiler drum 2 for detecting the surface position of any one of the slit coils. A winding thickening amount detecting means 7 that is movable upward in the radial direction is provided.

The moving body 6 includes a first moving means 13 that moves the paper piece supply means 5 in the axial direction of the recoiler drum 2 by rotating a threaded rod 13a with a horizontal movement motor 21, and a first moving means 13 that moves the paper strip supply means 5 in the axial direction of the recoiler drum 2 by rotating a threaded rod 14a.
The second moving means 14 moves the first moving means 13 upward in the radial direction of the recoiler drum 2. A paper strip supplying means 5 is attached to the tip of the first moving means 13, and even when the slit coil 3b is wound thickest as shown by the imaginary line in FIG. The movable body 6 serves to hold the paper strip supply means 5 such that the direction substantially corresponds to its winding position 3B'.

As shown in FIG. 2, the paper strip supply means 5 has a storage case 8 that stores the winding adjustment paper strips 4 in a stacked manner. This storage case 8 includes a paper strip shifting device 9 such as a cylinder that presses the paper strips 4 to stably maintain the stacked state of the paper strips 4 for tightening, and an extruder 11 such as a cylinder that pushes out the paper strips 4 in the paper strip supply direction 10. , and a pair of upper and lower supply rolls 12 are attached which feed the extruded paper piece 4 to the winding position 3B (see FIG. 3) of the metal strip 3 while sandwiching it. This supply roll 12 has a winding adjustment paper piece 4
The piece of paper 4 is held between the ends of the paper 4 until it reaches the winding position 3B of the slit coil 3b, for example. Although only one paper strip supply means 5 is shown in the drawing, a plurality of paper strip supply means 5 may be provided in the axial direction of the recoiler drum 2 depending on the scale of the slitter line.

The above-mentioned second moving means 14 is the first moving means 13
The paper strip supply means 5 mounted on the paper strip supply means 5 is raised and lowered according to the winding thickness of the slit coils 3a, 3b.
Although not shown, it is erected at a certain inclination angle in order to hold 2. On the other hand, an arm 15 is attached to the first moving means 13 so as to be parallel to the threaded rod 13a, and the paper strip supply position indicator 16 is located at the same position as the paper strip supply means 5 in the axial direction of the recoiler drum 2. The paper strip supply means 5 feeds the paper strips 4 to either slit coil.
Care has been taken to ensure that it is easy to confirm from the outside whether the company is supplying the necessary products.

The winding thickening amount detection means 7 is a slit coil 3
It detects the amount of winding thickening of slit coils a, 3b, . The winding thickening amount detection sensor 17 is for instructing how much the paper strip supply means 5 should be moved in the vertical direction. An optical sensor or the like is employed for this, and is always maintained at a substantially constant distance from the surface of the slit coil 3b by the sensor displacement motor 18. The second moving means 14 is driven in conjunction with the sensor displacement motor 18 to move the paper strip supply means 5 upward in the radial direction of the recoiler drum 2 and move it to the winding position 3.
Rolling thickness tracking motor 1 facing B, 3B'
9 is provided.

According to the embodiment having such a configuration, the winding adjustment paper piece 4 can be supplied to the slit coil remotely or automatically as necessary in the following manner.

First, the tip of the metal strip 3, which has been slit into a plurality of strips by a slitter installed on a slitter line, is inserted into an open notch (not shown) of the recoiler drum 2. After clamping and fixing it, the third
As shown in the figure, the recoiler drum 2 is rotated in the direction of arrow 20. The metal strips 3 adjacent to each other are ordered by a plurality of separators (not shown), and as shown in FIG.
It is wound up as... During this time, all the slit coils 3a, 3b, . That is, since the optical sensor 17 instructs the sensor displacement motor 18 to be driven so as to maintain a substantially constant distance from the coil surface position, the optical sensor 17 sequentially moves upward in the radial direction of the recoiler drum 2. Along with this movement, the first moving means 13 to which the paper strip supply means 5 is attached is moved upward by the bottom winding thickening following motor 19, and the delivery position of the winding adjustment adjustment paper strip 4 of the paper strip supply means 5 is adjusted. , slit coil 3a, 3
b... is adjusted so as to face each winding position 3B.

As the recoiler drum 2 rotates, if any of the metal strips 3 becomes loose during the winding process, the winding tightness of the slit coil becomes weaker. Visually confirming this condition,
A horizontal movement command lever on the operation panel is used to command the paper strip supplying means 5 located near the slit coil to move to the position 3B where the metal strip 3 is wound. The horizontal movement motor 21 is driven, and the first movement means 13 moves the paper piece supply means 5 to the recoiler drum 2.
is moved in the axial direction, and the paper strip supply means 5 is stopped at a desired slit coil position.

The extruder 11 in the storage case 8 is driven by the paper strip supply command lever on the operation panel, and the slit coil 3 is driven while holding the extruded paper strips 4.
A pair of supply rolls 12 to be delivered to the winding positions 3B of a, 3b, . . . are rotated by a roll drive motor 22. The winding adjustment paper piece 4 is supplied from the storage case 8 to the winding position, but at this time,
By setting the paper strip supply speed by the supply roll 12 to be slightly slower than the coil winding speed, the paper strip 4 can be smoothly inserted into the coil. As described above, if the supply roll 12 holds the paper strip 4 until the leading end of the paper strip 4 reaches the winding position of the slit coil, for example 3B in the figure, the supply direction of the winding adjustment paper strip 4 will be almost the same as that of the slit coil. It can be held in the winding direction. Therefore, it is possible to avoid the situation where the paper strip 4 deviates from the winding direction and the winding adjustment becomes insufficient.

As mentioned above, if the moving means 6 is provided with the paper strip supply position indicator 16, the light emitted from the indicator 16 will intensively illuminate a part of the surface of the slit coil as shown in FIG. You can check under which metal strip 3 the paper strip feeding means 5 is located, and if you want to move it to another slit coil, set the stop position while operating the horizontal movement command lever on the operation panel. You can know.

Incidentally, a plurality of winding thickness detection means 7 may be provided, but since the slit coil in the center of the recoiler drum 2 is often tight, it is sufficient to provide one above the slit coil. It is enough. Even if the winding thickening amount detected thereby is applied to other slit coils, there will be no problem in supplying the winding adjustment paper strip to the winding position.

FIG. 4 shows a different example in which the paper supply means 5 is positioned above the metal strip 3 and the direction of rotation of the recoiler drum 2 is reversed. In this case, since it can be easily confirmed which metal strip 3 the paper strip supply means 5 is located above, the paper strip supply position indicator 16 described above may be omitted.

As can be seen from the description of the embodiments above, in order to make all the slit coils wound around one recoiler drum tight, it is possible to remotely supply winding adjustment paper strips to desired slit coils at any time. Therefore, manual work at the winding site where the metal strip is moved is avoided, and the number of workers involved in operating the device can be reduced and rationalization can be achieved. Of course, it is possible to accurately and quickly supply the winding adjustment paper strip to the slit coil being wound at the required timing while maintaining the desired posture, and it is possible to obtain almost the same winding adjustment for all slit coils. It is possible to ensure constant quality. In addition, the amount of winding thickness of the slit coil is detected in a non-contact manner, and there is no wear and tear on the detection device due to wear etc., making it possible to realize stable operation over a long period of time.
