Description

[Detailed Description of the Invention] [Industrial field of application] The present invention does not cause various defects or defects in the coil surface layer when transferring a coil wound with a thin metal band. Moreover, the present invention relates to a coil car capable of efficient transfer processing.

[Conventional technology]

To attach a metal strip coil (hereinafter simply referred to as a coil) to the unwind reel of the unwinder in the metal strip processing equipment, or to extract the coil from the take up reel of the winder,
Generally, a coil car is used. As shown in FIG. 4, the conventional coil car has a concave coil so that the wheel 5 driven by the drive device 4 can support the trolley 6 traveling on the rail 10 by directly abutting the coil C on the outer peripheral surface thereof. A support base 14 and a hydraulic cylinder for moving the coil support base 14 up and down are provided. When this coil C is mounted on the reel 11 of the unwinder, it is carried by a coil lifter operated by an overhead crane. The coil C that came back is once placed on the coil skid 13, and then this coil skid
After moving the coil car directly below the coil C supported by the coil 13, the hydraulic cylinder provided in the carriage 6 is operated to raise the coil support base 14 above the coil skid 13 to move the coil C to the coil support base. The coil C is mounted on the reel 11 again, and then the coil car is moved to mount the coil C on the reel 11. And the mounted coil C
The sleeve S left on the reel 11 after being unwound into the processing equipment is taken out from the reel 11 by the coil car or the sleeve charger (discharger) which can be moved without confusion with the coil car as described above, and is used in the processing equipment. I am carrying it out. Further, in order to remove the coil C, which has been wound up on the sleeve S mounted on the winding reel of the winding machine, from the winding reel together with the sleeve S, the operation opposite to the operation for the unwinding reel is performed.

[Problems to be solved by the device]

In the structure and operation of the conventional coil car as described above, there was little problem when the plate thickness of the metal strip forming the coil was large. As the coil becomes larger in order to improve retention and productivity, the metal strip itself becomes weak and the weight of the coil becomes large, which causes contact with the coil skid of the coil and the coil support of the coil car. The part to be contacted becomes linear or nearly linear, and since a very large local force acts on this part, there are scratches or indented defects on the surface of the metal strip on the coil surface part of this contacting part. There is a problem in that stacking line defects occur in a substantially continuous state or a pitched state. And the thin metal strip is used for high-tech materials, for example, and it is required to have a strict quality without various flaws and surface defects in comparison with the thick metal strip in view of its application. This is the current situation. Therefore, when mounting the coil on the coil skid and the coil support, more inconvenient work is inevitably carried out by taking the latest precautions more slowly than before and loading it slowly and slowly. Even so, it was not possible to prevent the occurrence of the flaws and surface defects, and furthermore, the defective shape was also induced.

Therefore, the problem to be solved by the present invention is to solve the above-mentioned problems and to transfer the coil efficiently and efficiently so as not to cause various flaws and surface defects on the surface of the metal strip of the coil surface layer. It is to provide a coil car of a metal strip coil that can be processed.

[Means for Solving the Problems]

As a result of various studies by the present inventors in order to solve such a problem, when coiling a thin metal strip, various defects and surface defects as described above are prevented from occurring in the coil central portion. In order to keep the coil shape once it is transferred or transported, it is wound directly onto the reel of the winder as in the case of a thick metal strip. It is very rare to pay attention to the fact that the coil car is usually wound on the reel of the winder through the sleeve, and the coil car structure can support both ends of the sleeve protruding from both sides of the coil, The present invention has been completed focusing on the fact that the above-mentioned problems can be solved by constructing the apparatus so that a predetermined position can be vertically moved up and down in a synchronized manner so that transfer processing can be performed.

Hereinafter, the coil car according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a front view of one embodiment of a coil car according to the present invention,
FIG. 2 is a partial cross-sectional explanatory view of FIG. 1, and FIG. 3 is a schematic side view when a coil is mounted on a coil support base of a coil car from an overhead crane.

In the drawing, reference numeral 1 denotes a sleeve support base for supporting a sleeve S protruding from both sides of a coil C, and a rectangular sleeve support base guide 1a and this sleeve support base guide 1a.
It is composed of a sleeve pedestal 1b which is fixed to both sides of the upper end of 1a and supports both ends of the sleeve S, respectively. Reference numeral 2 denotes a hydraulic cylinder whose upper end is connected to the sleeve support base 1 via a bracket 3 and whose lower end is connected to a carriage 6 equipped with a drive device 4 and wheels 5, and the sleeve is operated by the hydraulic cylinder 2. The support base 1 can be raised and lowered. Reference numeral 7 denotes a cylindrical central guide such as a prism, which has a guide body 7a forming a wall portion and a bottom plate 7b to form a cup shape, and the guide body 7a is fixed to the carriage 6. There is. The guide body 7a of the central guide 7 is configured to guide the sleeve support base guide 1a of the sleeve support base 1 on its outer surface. Reference numeral 8 denotes a rectangular coil support base provided inside the cylindrical center guide 7, which is composed of a coil support base guide 8a forming a wall portion and a coil base 8b forming a ceiling portion. It is shaped like an inverted cup. The coil pedestal 8b is moved up and down with respect to the position of the coil C by a hydraulic cylinder 9 whose lower end is fixed to the bottom plate 7b of the central guide 7 at the center of the coil support pedestal 8 and the coil support pedestal The guide 8a is configured such that the outer surface thereof is guided by the guide body 7a of the central guide 7. The coil support base 8 has a thick metal strip that constitutes the coil C, so that the sleeve S is not used, or when the hydraulic cylinder 2 for raising and lowering the sleeve support base 1 of the coil car is malfunctioning, the sleeve support base 8 can be used. Since it is for directly supporting the coil C on its surface instead of 1, it may not be installed. Thus, in the illustrated embodiment, when the coil support base 8 does not exist, a double cylinder shape is formed outside the guide body 7a of the central guide 7 for guiding the sleeve support base guide 1a of the sleeve support base 1. Then
When the coil support base 8 is present, the sleeve support base guide 1a of the sleeve support base 1 is guided outside the guide main body 7a of the central guide 7 and the guide main body 7a of the central guide 7 is provided.
The coil supporting base guide 8a of the coil supporting base 8 is formed in the inside of this to form a triple cylindrical shape. In addition, 10 is a rail for running wheels 5 driven by a drive device 4 for running a dolly 6, 11 is a reel of a winder or an unwinder, and a metal strip plate forming a coil C. When the thickness is thin, the sleeve S is attached. 12 is a coil lifter suspended by an overhead crane.

[Action]

In order to mount the coil C with the sleeve S having a very thin metal band on the reel 11 of the unwinder by the coil car according to the present invention having the above-described structure, the hydraulic cylinder 2 is activated in advance to the center. The guide body 7a of the guide 7 guides the inner surface of the sleeve support base guide 1a of the sleeve support base 1 to raise the sleeve base 1b of the sleeve support base 1 to a level higher than the height of the coil skid. In this state, as shown in FIG. 3, the sleeve S protruding from both ends of the coil C suspended by the coil lifter 12 suspended by the overhead crane is placed and supported on the sleeve pedestal 1b. At this time, the coil support base 8 is made to stand by at the lowest position by the hydraulic cylinder 9 as shown in FIG. After that, the hydraulic cylinder 2 is operated to raise the center of the sleeve S supported by the sleeve pedestal 1b of the sleeve support 1 to a height substantially matching the center of the reel 11 of the unwinder and drive the drive unit 4. Then, when the wheels 5 are run on the running rails 10 and the dolly 6 is moved to directly below the reel 11 of the unwinder, the sleeve S is mounted on the reel 11.

On the other hand, in order to extract the coil C with the sleeve S having a very thin metal band wound up from the reel 11 from the reel 11 of the winding machine and perform the transfer process, the sleeve pedestal 1b of the sleeve support base 1 is used.
Also, with the coil pedestal 8b of the coil support base 8 standing by at the lowest position by the hydraulic cylinders 2 and 9, the drive device 4 is driven to cause the wheels 5 to travel on the travel rails 10 and the dolly 6 to be wound. The reel 11 of the machine is moved to a position immediately below, and then the hydraulic cylinder 2 is operated to guide the inner surface of the sleeve support base guide 1a of the sleeve support base 1 by the guide main body 7a of the central guide 7 to move the sleeve support base 1a. The sleeve pedestal 1b is raised above the height of the coil skid to a height at which it abuts the sleeve S mounted on the reel 11 of the winder, and in this state the diameter of the reel 11 of the winder is reduced. And sleeve S
Since the attached coil C is in a state in which the sleeve S is completely supported by the sleeve pedestal 1b of the sleeve support base 1, the drive device 4 is driven again to cause the wheels 5 to travel on the traveling rails 10 and the dolly. The coil C can be pulled out from the reel 11 by moving 6 in a direction away from directly below the reel 11 of the winding machine.

In addition, the coil C not coiled to the sleeve S
In the case where the sleeve pedestal 1b of the sleeve support 1 cannot be raised to the height at which the sleeve S can be attached / detached to / from the reel 11 of the unwinder or winder due to a failure of the hydraulic cylinder 2 or the like, the sleeve support 1 With the sleeve pedestal 1b and the coil pedestal 8b of the coil support 8 kept waiting at the lowest position by the hydraulic cylinders 2 and 9, the drive unit 4 is driven to drive the wheels 5 on the rails 10 for traveling. The carriage 6 directly below the reel 11 of the winder, and then the hydraulic cylinder 9 is operated to guide the outer surface of the coil support base guide 8a of the coil support base 8 by the guide body 7a of the central guide 7 to form the coil. The coil pedestal 8b of the support base 8 is raised above the height of the coil skid to a height at which it comes into contact with the coil C or the sleeve S mounted on the reel 11, and the coil C or the sleeve S is moved in the same manner as the conventional coil car. Is the it is sufficient to desorb direct support to.

[Effect of device]

As described in detail above, the coil car according to the present invention includes a sleeve support base that is fixed to the carriage by a hydraulic guide cylinder whose lower end is connected to the carriage. Since the structure is provided with the sleeve pedestal that supports both ends of the sleeve that is guided by the guide for the coil and projects from both sides of the coil, it does not come into contact with the metal strip surface of the coil from both sides of the coil. Since the coil can be supported and transferred by directly supporting the protruding sleeve, not only the work efficiency and transfer efficiency can be improved more efficiently than before, but also various surface defects on the metal strip surface of the coil surface layer can be achieved. It is possible to eliminate the disadvantage that the coil shape is lost or the coil shape is destroyed during the transfer process.

And, the sleeve support base guide of the sleeve support base and the guide body of the central guide are both formed in a tubular shape, and the sleeve support base is located outside the central guide to form a double tubular shape. Not only does the central guide have greater rigidity and stability as a guide, but it also eliminates the use of complicated structures such as dovetail grooves to ensure the engagement of the sleeve support with the guide for the sleeve support. Even if the sleeve support is lifted and lowered stably, the hydraulic cylinder and various connecting parts are not subjected to excessive force, and the transfer process such as coil attachment / detachment can be performed with almost no failure.

A coil pedestal that directly supports the coil on its upper surface by a cylinder whose bottom end is fixed to the bottom plate of the central guide and which is guided up and down by a guide body of the central guide. When the coil is provided, it can be used in the same manner as before even when transporting a coil of a metal strip having a relatively large plate thickness, which often does not use a sleeve, and versatility occurs. At the same time, even if the sleeve support cannot move up and down due to a failure, the coil support can be used temporarily, so that it is not necessary to immediately stop the line and the productivity is improved.

The sleeve support base guide of the sleeve support base, the guide body of the central guide, and the coil support base guide of the coil support base form a tubular shape, and the sleeve support base is located outside the central guide, and the central guide In the case where the coil supporting base is present inside the to form a triple cylindrical shape, in addition to the effect in the case where the sleeve supporting base is located outside the central guide to form the double cylindrical shape, The vertical movement of the coil support base in the center is more stable, and even if one of the coil support bases moves up and down from the sleeve support base, the sleeve support base guide of the sleeve support base, the center guide guide body, and the coil support base Due to the three-layer structure of the coil support base guide, the moving guide is held by the two layers of the guide body of the central guide and other non-moving guides. Since safety in degrees surface is higher is the response to large and heavy reduction of the coil is facilitated.

Thus, the practical value of the present invention having various effects is extremely great.
