Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a steel strip coil turning device.

<Conventional technology> Conventionally, a rope coil (hereinafter simply referred to as a coil) that has been wound up with a winding machine is placed on a trolley or the like and conveyed linearly on rails while being subjected to various treatments. In a line, when coils are bound with a hoop, marked, or temporarily fixed with tape or the like at the tail end of the coil, the direction of the coil may have to be changed.

When changing the direction of the coil, it has been common practice to use an overhead crane installed in the line building to handle the coil each time.

<Problem to be solved by the invention> However, when using an overhead crane, manual labor is always required for operation, slinging, and signaling, and when there are few installed cranes, there are problems such as inefficiency as processing cannot be done in a timely manner. There is.

One way to solve this problem is to incorporate a turning device such as a turntable that turns the coil on a horizontal plane into the conveying line, as disclosed in Japanese Patent Application Laid-Open No. 63-220925. be.

As shown in FIG. 5, a skid 3 supporting a coil 1 is integrated with a ring gear 6 rotatably supported by a frame 5 erected on a floor 4.

Then, by driving the motor 7, the pinion gear 8
Since the ring gear 6 can be rotated through the coil 1, the direction of the coil 1 can be changed in any direction.

However, although this method can be applied when the coil is transported by a conveyor or a walking beam, there is a problem in that it is extremely difficult to apply when a transport vehicle (hereinafter simply referred to as a vehicle) is used.

The present invention has been made to solve the above-mentioned problems, and provides a steel strip coil turning device suitable for easily changing the direction of the coil even when the coil is transported using a trolley. The purpose is to capture and provide information.

Means for Solving the Problems> A first aspect of the present invention is a device for turning in a horizontal plane a steel strip coil conveyed by a conveyor truck running on a main rail laid in a straight line, A turntable is provided in the middle of the rail, two pairs of connection rails having the same width as the rails are provided orthogonally on the turntable, and two pairs of connection rails that are orthogonal to each other are provided on the turntable. This steel strip coil turning device is characterized in that a skid is provided on the outside of the rail to allow the mesh strip coil to move up and down.

In a second aspect of the present invention, the turntable is shaped like a doughnut, and a connection rail is fixedly provided on the inner peripheral surface of the turntable along an extension line of the main rail. This is a rotating device for band coils.

<Function> According to the first aspect of the present invention, a rotatable turntable is provided with a rail orthogonal to the linear rail, and a skid is provided that allows the coil to be moved up and down. Therefore, the direction of the coil can be changed easily and smoothly by a combination of the operation of moving the cart in and out of the turntable and the operation of raising and lowering the coil on the cart.

Further, according to the second aspect of the present invention, since the turntable has a donut shape, it is possible to suppress vibrations that the cart receives when the cart is put in and taken out from the turntable, thereby preventing surface flaws on the coil. It is also possible to prevent such occurrences.

<Example> Below, an example of the turning device of the present invention will be described in detail with reference to the drawings.

[Example I]

FIG. 1 is a plan view illustrating the outline of a first embodiment of a turning device according to the present invention, and FIG. 2 is a cross-sectional view taken along the line A-A.

As shown in the figure, a turntable IO is provided between the main rails 9 laid in a straight line, and two pairs of connection rails 11a, 11b orthogonal to each other are arranged on the turntable 10.

At the intersection of these rails 11a and 11b, the coil 1 is connected to the i! A gap g is provided through which the flange portion of the wheel of the placed cart 12 can pass.

Further, on the outside of the rails 11a and 11b on the turntable 10, four coil receivers 14 are provided that can be raised and lowered by a lifting device 13 such as a fluid pressure cylinder.

On the other hand, the turntable 10 is configured integrally with, for example, a ring gear I5, and is rotationally driven by a motor 17 via a pinion gear 16.

The operation of the swing device configured in this way will be explained below.

■ First, as shown in Fig. 2, the bogie 1 has the coil 1 placed on it with both side edges parallel to the longitudinal direction of the main rail 9.
2 is run from the left side with respect to the plane of the paper and stopped on the turntable 10.

(2) Next, the coil receiver raises the skid 14 by operating the lifting device 13, and lifts the coil 1 from above the truck 12.

(2) Then, the truck 12 is moved backward or forward, and is once placed outside the turntable 10 to wait on the main rail 9.

- Drive the motor 17 to rotate the turntable 10 by 90 degrees. This means that the direction of the coil 1 has been changed by 90 degrees.

(2) Then, the truck 12 is pulled onto the turntable 10 again and stopped, and the coil receiver lowers the skid 14 and places the coil 1 on the truck 12 again.

■ At this time, the direction of the coil 1 on the trolley 12 is T degree 9
Since the direction has been changed by 0°, the cart 12 is moved to the next process as it is.

(Example ■) In the above-mentioned Example I, a gap g is provided at the cross portion of the orthogonal rails 1a and 11b on the turntable 10, so that when the cart 12 moves in and out on the turntable 10, Since it generates a considerable amount of vibration, it may cause surface flaws when transporting extremely thin coils.

Therefore, in order to process such high-grade products, it is recommended to use a turntable 10A as shown in FIG. A connecting rail 11c is fixedly laid on the peripheral surface on an extension of the main rail 9.

By configuring the donut-shaped turntable IOA in this way, the cross portion shown in the above-mentioned embodiment I can be eliminated.
The direction of the coil 1 can be changed silently without causing vibration when moving it in and out.

In addition, in the case of this embodiment, if the distance between the front and rear wheels of the truck 12 is within the range of the length of the rail 11c, the truck 12 can be kept on standby on the rail 11c while the direction of the coil l is changed. This has the effect that the time required for handling the loading and unloading of the trolley 12 can be shortened.

<Effects of the Invention> As explained above, according to the first aspect of the present invention, since two pairs of orthogonal connection rails are arranged on the turntable, it is easy to change the direction of the coil orientation. conversion can be performed, and processing efficiency in the processing line can be increased.

Further, according to the second aspect of the present invention, since the turntable is formed in a donut shape, vibrations when the cart is moved in and out of the turntable can be suppressed, and furthermore, the quality of the product can be prevented from deteriorating. Contribute to prevention.
