Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a drum device for winding a long body.Specifically, the present invention relates to a drum device of a new configuration suitable for use in a horizontal continuous annealing furnace, etc. This is related.

“Conventional technology” A horizontal continuous annealing furnace is used to process unannealed elongated bodies (hereinafter referred to as
An annealing furnace that sequentially and sequentially anneales an untreated elongated object (or simply referred to as an elongated object) while horizontally conveying the elongated object; An indispensable component is an annealing furnace or the like that is installed in the middle of the apparatus and sequentially anneals the elongated bodies that are transported.

By the way, the following two methods can be considered as methods of supplying the unprocessed elongate body to the transport device.

One is to cut a long body to a predetermined length in advance,
One method is to manually or mechanically place the unprocessed long body onto a predetermined position on the conveying device.The other method is to wind the unprocessed long body around a drum in advance, and then install this drum at the base end of the conveying device. In this method, the unprocessed long body wound around a drum is fed out to a conveying device at a predetermined speed.

``Problem that the invention aims to solve'' Of the two methods mentioned above, the former is a method that has been used more often than before, but the length of the unprocessed long object depends on the size of the conveyor and the It is limited by the ability to convey unprocessed lengths onto the conveyor. In other words, if you want to anneal a longer object, you will have to increase the length of the conveyor, and if the throughput increases, the number of times you will carry in and out the long object will increase accordingly. There was a problem that the burden on the workers increased.

On the other hand, in the latter method, the length of the conveying device only needs to be somewhat larger than the length of the annealing furnace, and is not related to the length of the elongated body itself to be annealed.
The problems in the former method can be solved.

Therefore, recently, various studies have been conducted on the use of the latter method, but in using this latter method, the following technical problems must be solved.

If the elongated body is a metal plate material (rolled material) or a filamentous body, and the unprocessed elongated body is wound around a drum and has curls, remove the curls and transfer it to the conveying device. that must be supplied.

Consideration should be given to prevent unnecessary tension from acting on the elongated object during annealing by preventing fluctuations in the conveyance speed of the elongated object by the conveying device.

When you start winding a long body on a drum for wrapping an untreated long body or a drum for wrapping an annealed long body, you can easily fix the tip of the long body. Take care to ensure that.

Regarding the above-mentioned problem, among the plurality of straightening rollers arranged in upper and lower stages, the center axis of the rollers in one stage is located between the adjacent rollers in the other stage, and the upper and lower rollers are This problem can be solved by installing a device called a leveler, which has a staggered arrangement.

However, if the elongated body wound around the drum has small dimensions such as thickness and diameter and is highly flexible, curling is unlikely to occur; With a leveler, it is not possible to properly feed out a long body from a drum. Therefore, in such cases, a device called a pinch roller, in which the central axes of the upper and lower rollers are set on the same vertical plane, is required, but it is necessary to have both a leveler and a pinch roller on hand. There is a lot of waste in terms of installation space and equipment costs.

On the other hand, the above-mentioned problem can be solved by synchronizing the feeding speed of the untreated long body by the leveler or pinch roller and the conveyance speed by the conveying device that feeds the untreated long body into the annealing furnace. Yes, but it takes a long time to anneal.
As a result, the conveyance speed itself becomes very slow, making it relatively difficult to synchronize accurately. An important requirement is to devise ingenuity to simplify the mechanism.

Furthermore, in order to solve the above-mentioned problem, the method of pasting the tip of the elongate body to the outer circumferential surface of the drum using adhesive tape has been implemented up to now, but with this method, the thickness and diameter of the elongate body cannot be adjusted. If the length of the object is large and the long object to be wrapped has low flexibility or high rigidity, it is difficult to securely fix the object. There were problems such as having to monitor the process until it was repeated twice.

This idea was made in view of the above circumstances, and allows the tip of the long body to be firmly and easily fixed without being affected by the flexibility of the long body when starting to wind the long body. The object of the present invention is to provide a drum device suitable for use in a continuous annealing furnace or the like.

"Means for Solving the Problems" In order to achieve the above-mentioned purpose, the drum device for a continuous annealing furnace according to this invention includes a cylindrical sleeve around which a long body is wound, and a radial direction within the sleeve. a sleeve holding mechanism that fixes the sleeve by moving a plurality of movable pawls arranged in a concentric circle and moving these pawls radially outward to bring them into close contact with the inner circumferential surface of the sleeve, and It is essential that the peripheral wall of the sleeve is provided with a through hole into which the tip of the elongated body is inserted.

"Operation" In a drum device having such a configuration, the sleeve is inserted into the sleeve so that the diameter of the circle formed by the plurality of pawls is reduced and these pawls are inserted into the sleeve. The sleeve is held by attaching it to the retaining mechanism and then moving each of the pawls radially outward, but before moving the pawls radially outward, If the tip of the elongated body is inserted through the through hole of the sleeve so that the tip protrudes into the sleeve, the strong force applied to the pawl will push the elongated body into place when the sleeve is held. The distal end of the elongated body is held between the pawl and the inner circumferential surface of the sleeve, and the distal end of the elongated body is firmly fixed at the same time as the sleeve holding operation is completed.

In other words, the work of fixing the elongated body to the sleeve is simply to insert the tip of the elongated body into the through hole provided in the sleeve, and the operation of holding the sleeve in the sleeve holding mechanism simultaneously fixes the elongated body to the sleeve. Since the fixing work is completed, no extra work time is required, and the tip of the long object can be firmly fixed to the sleeve very easily and in a short time. For example, horizontal continuous annealing By using it in an apparatus, etc., it becomes possible to replace the elongated body easily and in a short time, and it becomes possible to construct a horizontal continuous annealing furnace that is easier to use.

In the above explanation, it has been mentioned that the upper support stands 14 and 15 were provided with screw insertion holes 20 at five places, and the intermediate support stand 17 was provided with female screws 21 at six places. The reason for this is that the feeding device 4 can be easily switched and used both as a leveler and as a pinch roller.

33 etc. serve as a power transmission mechanism to the conveying device 5, and this power transmission mechanism further includes sprockets 26, 30.
A, 30b, 31, etc. are added to form a power transmission mechanism to the feeding device 4. As the motor 9, a variable speed motor that can stably perform low speed operation is selected to stabilize the conveying speed and feeding speed.

The winding drum device 6 is rotationally driven by a dedicated motor, and the rotation speed of this motor is controlled by the winding control device 8 according to the transport speed of the transport device 5. Ru.

Briefly, this winding control device 8 has a roller 41 provided at the tip of an arm 40 whose base end is rotatably supported, as shown in FIG. The conveying device 5 and the winding drum device 6
When the conveyance speed changes, the angle of the arm 40 is detected. If the angle of the arm 40 changes due to the change in the conveyance speed, , the rotation speed of the motor that drives the drum 6 is changed accordingly, and the rotation speed detector 4 detects the rotation speed of the aforementioned motor 9.

As mentioned above, the drum device 6 is related to the present invention, and as shown in FIGS. 7 and 8,
Cylindrical sleeve 50 around which the elongated body is wrapped
The sleeve holding mechanism 51 holds the sleeve 50 and transmits rotational force to the sleeve 50 during winding, and flanges 52 are detachably provided on both sides of the sleeve 50.

The sleeve holding mechanism 51 connects a plurality of (three in this embodiment) pawls 53, which are arranged concentrically and can be inserted into the sleeve 50, to a central shaft 55 through a kind of parallel link mechanism 54, respectively. By connecting the central shaft 55 in the axial direction (the direction indicated by the arrow H in the figure), the pawls 53 can be moved back and forth in the radial direction at the same time. Each nail inserted 5
The sleeve 50 is held by enlarging the diameter of the circle 3 and pressing the pawl 53 against the inner peripheral surface of the sleeve 50. The force of each pawl 53 pressing against the inner circumferential surface of the sleeve 50 is sufficiently strong;
The strength of the parallel link mechanism 54 and the central shaft 55 and the forward and backward force transmitted to the central shaft 55 are set so that the sleeve 50 can be firmly fixed.

On the peripheral wall of the sleeve 50, each pawl 5 described above is provided.
3, a through hole 56 into which the tip of the elongated body 3 is inserted is provided. This through hole 56 is
As shown in FIG. 8, it is provided at an angle of 45 degrees with respect to the normal line.

In such a drum device 6, the diameter of the circle formed by the three pawls 53 is reduced so that these pawls 53 are connected to the sleeve 5.
By attaching the sleeve 50 to the sleeve holding mechanism 51 so that the sleeve 50 is inserted into the sleeve 0, and then moving each pawl 53 radially outward,
The sleeve 50 is held, but before moving the pawl 53 radially outward, the distal end of the elongated body 3 is moved so that the distal end of the elongated body 3 protrudes into the sleeve 50. If the sleeve 50 is inserted into the through-hole 56 of the sleeve 50 by pushing it along the arrow t in FIG. is held between the pawl 53 and the inner circumferential surface of the sleeve 50, and at the same time as the holding operation of the sleeve 50 is completed, the tip of the elongated body 3 becomes firmly fixed.

In other words, the work of fixing the elongated body 3 to the sleeve 50 is simply to insert the tip of the elongated body 3 into the through hole 56 provided in the sleeve 50, and the sleeve 50 is held in the sleeve holding mechanism 51. Since the work of fixing the elongated body 3 is completed at the same time, the tip of the elongated body 3 can be attached to the sleeve 50 very easily, in a short time, and firmly, without requiring any extra work time. This makes it possible to increase the working efficiency in the horizontal continuous annealing furnace 1.

Hereinafter, a case where the elongated body 3 is annealed using the annealing furnace 1 will be briefly described.

In advance, considering the plate thickness of the elongated body 3 to be annealed,
Whether the feeding device 4 functions as a leveler,
It is selected whether or not to function as a pinch roller, and the mutual positional relationship between the upper and lower rollers 11 and 12 of the feeding device 4 is set accordingly.

Then, the tip of the elongated body 3 wound around the feeding drum device 2 is attached to the upper and lower rollers 11 and 12.
If the motor 9 is operated during this period, the feeding device 4 and the conveying device 5 are operated synchronously, and the elongated body 3 is fed into the annealing furnace 7 at a predetermined speed, and annealing is performed continuously. The ones that have been annealed are sequentially sent to the winding drum device 6 side. The tip of the elongated body 3 sent to the drum device 6 side can be easily fixed to the sleeve 50 by simply inserting it into the through hole 56 of the sleeve 50, and the sleeve 50 can be rotated according to the conveyance speed. By driving, the sleeve 50 is wound up in order.

In this way, in the annealing furnace 1, the feeding device 4 and the conveying device 5 are operated by a single motor 9.
As shown in the embodiment, a simple transmission mechanism consisting of a combination of simple members such as a sprocket and a chain is sufficient to control the feeding speed by the feeding device 4 and the conveying speed by the conveying speed 5. It is possible to perform annealing continuously by accurately synchronizing the elements, and therefore, it is possible to prevent excessive tension from being applied to the elongated body 3 during annealing work. Complication of mechanisms and control mechanisms can be avoided.

Further, the feeding device 4 has an upper support base 14,1
5 and the intermediate support base 17, the elongated body wound on the feeding drum device 2 can be easily functioned as both a leveler and a pinch roller. 3 can be fed out and supplied to the conveying device 5 without being affected by the flexibility etc. of the elongated body 3,
Furthermore, compared to the case where both a dedicated leveler machine and a dedicated pinch roller machine are simply installed side by side, installation space and production costs can be significantly reduced.

Further, in the annealing furnace 1, when annealing is started, the work of fixing the tip of the elongated body 3 that has passed through the annealing furnace 7 to the sleeve 50 of the winding drum device 6 is simply to fix the tip of the elongated body 3 to the sleeve 50 of the winding drum device 6. It is only necessary to insert the sleeve 50 into the through hole 56 provided in the sleeve 50, and the operation of holding the sleeve 50 in the sleeve holding mechanism 51 completes the work of fixing the elongated body 3 at the same time, so extra work time is required. The distal end of the elongated body 3 can be firmly fixed to the sleeve 50 very easily, in a short time, and without any problems.
As a result, the working efficiency in the horizontal continuous annealing furnace 1 is also improved.

In addition, in the above-mentioned annealing furnace 1, only the drum device for winding 6 is a drum device according to the present invention, but the drum device for feeding 2 may also have a similar configuration.

"Effects of the Invention" As is clear from the above explanation, the drum device of the present invention includes a cylindrical sleeve around which a long body is wound, and a plurality of concentric pawls movable in the radial direction within the sleeve. and a sleeve holding mechanism for fixing the sleeve by moving these pawls radially outward and bringing them into close contact with the inner circumferential surface of the sleeve. The sleeve is held in such a way that the diameter of the circle formed by the plurality of pawls is reduced and these pawls are inserted into the sleeve, with a through hole into which the tip is inserted. The sleeve is held in place by mounting it on the mechanism and then moving each of the pawls radially outward;
Before moving the pawl radially outward, the sleeve can be held by inserting the distal end of the elongated body through the through hole of the sleeve so that the distal end of the elongated body projects into the sleeve. At this time, the tip of the elongated body is held between the pawl and the inner peripheral surface of the sleeve due to the strong force applied to the pawl, and at the same time the sleeve holding operation is completed, the tip of the elongated body is firmly held. It will be fixed at .

In other words, the work of fixing the elongated body to the sleeve is simply to insert the tip of the elongated body into the through hole provided in the sleeve, and the operation of holding the sleeve in the sleeve holding mechanism simultaneously fixes the elongated body to the sleeve. Since the fixing work is completed, no extra work time is required, and the tip of the long object can be firmly fixed to the sleeve very easily and in a short time. For example, horizontal continuous annealing By using it in furnaces, etc., you can easily replace long objects.
In addition, it can be completed in a short time, and excellent effects such as being able to construct a horizontal continuous annealing furnace that is easier to use can be obtained.
