Abstract

PURPOSE:To allow the winding direction of a coil coincident with the fastening direction of a binder and to tightly bind a coil at all times by arranging the revolving device revolving a coil on a horizontal plane to a transfer route. CONSTITUTION:A coil is taken off from a winder 3 by a coil car 2 first and transferred to the position of a revolving device 8. In the case of the winding direction of the coil being coincident with the fastening direction of the hoop of a binder, it is bound by transferring to the position of the binder by a walking beam 5 as it is. However, in the case of the coil winding direction being differed from the hoop fastening direction, the revolving device 8 is revolved 180 deg. in the state of loading the coil to allow the coil winding direction coincident with the hoop fastening direction. Thereafter, it is bound by transferring to the position of the binder 6 by the walking beam 5. Consequently the coil always bound tightly can be fed to the succeeding stage.

Description

[Detailed Description of the Invention] <Object of the Invention> Industrial Application Field The present invention relates to a conveying facility for steel strip coils, and more specifically, the present invention relates to a conveying facility for steel strip coils, and more specifically, the present invention relates to conveying equipment for steel strip coils, and more specifically, in a process line for surface treatment, etc. Concerning conveyance equipment for band coils.

Conventional technology In a surface treatment process line that performs plating, etc. on steel strip, different treatments may be applied to the front and back surfaces of the steel strip. For example, if we take a plating line as an example,
Depending on the user's request, a different plating layer may be formed on the i-plane or a difference may be provided in the plating thickness. When the processing specifications for the front and back surfaces are different in this way, the method of winding the processed coil may also be specified by the user's request. Specifically, as shown in Fig. 3(a), the steel strip is rolled so that the top surface is on the outside.
There are two types of winding methods: "lower winding" and "lower winding", in which the coil is wound inward.The coil shape with slow winding is shown in Figure 3 (b).
(in the case of upper winding), (C) (in the case of lower winding). The coil wound in this way is received by the lifting frame 2a of the coil car 2, and is sent to the winding machine 3a.
It is pulled out more toward the front of the page.

FIG. 4(a) shows an example of equipment for conveying the wound coil, and the operation of each device will be explained below.

``The coil 1 is pulled out from the winder roll 3a by the coil car 2 and transferred to the coil conveyor 4 arranged parallel to the line. The coils 1 transferred to the coil conveyor 4 are conveyed one after another at a constant pitch, and are conveyed to the taking-in position of the walking beam 5. The method of capturing by the walking beam 5 is as follows.

The movable beam 5a moves forward to the lower part of the coil 1 with respect to the waiting coil 1, and after stopping F, lifts up the coil by a lift mechanism (not shown), and in that state retreats by a predetermined stroke and places it on the fixed skid 5b. The coils are taken in one by one through a series of transfer operations. Figure 4 (old,
(cl and (d) show the connection relationship of each device. In the example of FIG. 4, the bundle I (3) is installed at the first position taken into the walking beam 5.

The outer periphery of the transported coil 1 is hoop bound by this binding machine 6, but in cases where there are two ways to wind the coil: top winding and bottom winding, the current method is as follows. This is causing problems.

First, the method of bundling the coils will be explained with reference to FIG. The binding hoop 7 is pinched by a hoop feeding pinch roll 6a, and is sent out by driving the pinch roll 6a. The fed hoop goes around the outer periphery of the coil once along a hoop guide (not shown), and the tip of the hoop is clamped by a clamp built into the binding head 6b. In this state, the pinch roll 6a is rotated in the opposite direction to pull back the hoop, and the binding head 6b is lowered by a lifting device (not shown) until it contacts the tip of the coil, and the hoop is wound around the outer periphery of the coil. Furthermore, in order to increase the adhesion of the hoop to the outer periphery of the coil, the hoop is pulled back by the pinch roll 6a to apply a predetermined tension, and the hoop tips are spot welded by overlapping the hoops that are close to the upper surface. (built-in to the binding head) and completes the binding (sometimes crimped with grip metal fittings). In this case, if the tightening direction of the hoop 7 is the same as the winding direction of the coil as shown in FIGS. If the tightening direction of the hoop is different from the coil winding direction as shown in FIGS. 6(al) and (b), in the case of a thin steel strip, the tail end of the coil will be folded and folded, as shown in FIG. 7(a). This may cause wrinkles and cause surface flaws on the steel strip directly below.Also, in the case of relatively thick steel strips, the tail end may bend as shown in Figure 7(b), causing gaps to be filled. This may occur.

If this gap occurs, when handling with coil tongs, etc., several turns on the outer circumference of the coil may become loose, and when tension is applied to the steel strip during unwinding during the erosion process, the windings become tighter, causing overlapping Slip may occur between the steel strips, resulting in surface flaws. in this way,
When binding the outer circumference of a coil using a binding machine, it is necessary that the tightening direction of the hoop and the winding direction of the coil match. In cases where the hoop is tied with a conventional equipment configuration in which the coil is conveyed horizontally as it is wound with a winder as shown in Figure 4, there is no option other than installing two tying machines with different hoop tightening directions. It was impossible to deal with it.

Problems to be Solved by the Invention The present invention aims to solve these problems, and specifically, the coil is wound at an angle of 18 degrees on a horizontal plane during the coil conveyance path from the winding machine to the binding machine.

An object of the present invention is to provide coil conveyance equipment having a turning device that turns.

<Structure of the Invention> Means for Solving the Problems and Their Effects The present invention provides a means for solving the problem and its operation in a steel strip coil conveying facility for conveying a coil extracted from a winding machine on the exit side of a process line for steel strips, etc. to a binding machine. The present invention is characterized in that a turning device for turning the coil on a horizontal plane is disposed on the transfer route of the transfer equipment.

FIGS. 1(a) and (b) are a plan view and a vertical cross-sectional view in the direction of arrow A-A in FIG. 2(a) and (formerly 3(a) are plan views showing other examples of the conveyance equipment according to the present invention, and FIG.
1 is an explanatory diagram showing the coil winding method, and FIGS. (C) and (di) are a plan view showing an example of conventional conveyance equipment and longitudinal cross-sectional views in the directions of arrows B-B, CC, and D-D in (a); and (bl) are explanatory diagrams when the coils are bundled (when the hoop tightening direction is the same as the coil winding direction), and in Fig. 6 1a) and (b), the hoop tightening direction is the coil winding direction. FIG. 7 fa'l and fb) are explanatory diagrams showing trouble situations during bundling, respectively.

That is, in the present invention, during the coil conveyance path from the winding machine to the binding machine, every time the wound coil is rotated 1806 times in the horizontal plane F, the wound coil is transported in a direction different from the winding direction of the coil binding machine. This is a steel strip coil conveying equipment that can always tightly bind coils even if the winding direction is made to match the winding direction of the binding machine.

Hereinafter, the configuration of the conveyance equipment according to the present invention will be explained with reference to FIGS. 1(at and 1b).

Fig. 1 (a'+ is the coil 1 wound by the winding machine 3.
was taken out by the coil car 2, the coil was transferred directly to the turning device @ 8 provided on the extension line in the direction of movement of the coil car, and the coil was turned. After that, the coil car 2 was slowly retreated, and the coil was taken in by the walking beam 5. This is an embodiment in which the binding machine 6 is placed at the initial position taken in by the walking beam 5. When transporting a coil wound in a top-wound state by a winding machine, first, the coil car 2 takes it out from the winding machine 3 and transports it to the position of the turning device @8. Here, if the winding direction of the coil matches the hoop tightening direction of the binding machine, the coil is directly transported by the walking beam to the binding machine of the binding machine and bound.

However, if the winding direction of the coil is different from the hoop tightening direction, the swivel @8 should be rotated 180° with the coil loaded.
Rotate the coil so that the winding direction of the coil matches the hoop tightening direction. Then, the walking beam 5 transports it to the position of binding @a and bundles it. In this way, the coil conveyance equipment from the winding position 113 to the binding position 13G (
If a device is installed to rotate the winding coil 180 degrees at the location (including the bundling position), tightly bound coils can always be supplied to the subsequent process, and there is no risk of surface flaws. Since there is no need to install two machines, equipment costs can be reduced, space can be used effectively, and equipment can be configured simply.

FIG. 1(b) shows the equipment configuration of the turning device @8 used in the coil conveyance equipment according to the present invention.
FIG. 1 is a longitudinal cross-sectional view taken along arrow A-A of FIG.

In the figure, 88 is a skid that supports the coil 1, and 8b is a ring gear, which is integrated with 88. A pinion gear 8C driven by a motor 8d meshes with one location on the circumference of the ring gear 8b. Further, a turn bearing that rotatably supports the skid 8a and the ring gear 8b is incorporated in the frame 8e, and the skid portion 8a is configured to rotate when the motor 8d is driven.

Fig. 2 (al shows two swivel units M8 on the way to binding machine G.
In this example, the winding direction of the coil and the direction of tightening the hoop are made to match each other by rotating the hoop by 90' using each rotating device.

In FIG. 2(b), a cart 8' with a swivel device (hereinafter referred to as a cart) is arranged in place of the swivel device 8 in FIG. 1 (al), and further,
A conveyor 5' is placed in place of the walking beam 5. At a position where the cart 8' is shifted to the left side of the paper, empty barre I/cart 01\11 is transferred from the conveyor 5'', and after the transfer, the cart 8 is moved to the left side. ' is shifted to the right side of the paper] When the coil 1 is received from the coil car 2, the cart 8' is rotated 180 degrees to match the winding direction of the coil and the hoop tightening direction.

The pallet carts are transferred from the conveyor 5'' to the cart 8' and from the cart 8' to the conveyor 5' by feeders 12 installed on the respective conveyors.

Although the case of a binding machine has been described above, the equipment according to the present invention can also be applied to the installation of a device for temporarily fixing the tail ends of coils by pasting tape, a device for marking coils, and the like.

<Effects of the Invention> As explained above, the present invention provides a steel strip coil transportation facility that transports coils handled from a process line exit winder for steel strips, etc. to a binding machine. A conveying equipment for steel strip coils, characterized in that a conveying path is provided with a turning device for rotating the coil on a horizontal plane, and according to the present invention, even if the winding direction of the coil binding machine is Even if coils wound in different directions are transported, the winding direction of the coil can be matched with the tightening direction of the binding machine by rotating the coil receiving skid on which the coil is transferred, so the coil can always be wound. We are now able to unite closely.
