Description

[Detailed description of the invention] This invention relates to a material transfer device, and more specifically, it is a walking beam type material transfer device that rotationally transfers material by relative motion between a fixed beam and a moving beam. It is suitable for cooling while rotating and feeding.

When manufacturing prismatic materials such as billets,
When cooling a material to improve its quality, it is necessary to uniformly cool each side of the material to equalize the material temperature, prevent bending during the cooling process, and correct the bending of the material itself. . Recently,
As the production volume of materials increased, work to improve the quality of materials, including the above processes, became more complicated.
The above-mentioned cooling work is performed without requiring as much manual labor as possible, and the cooling time of the material is shortened, that is,
There is a desire to speed up the cooling rate and downsize the equipment.

In order to meet the above-mentioned demands, technology has recently been developed to transport materials in a cooling bed, and in particular,
The most promising device is a walking beam type material feeding device that does not come into contact with others during the material feeding process and does not damage the material.

This invention is a walking beam type material transfer device that transfers material by relative movement between a fixed beam and a moving beam, in which a sawtooth-shaped chevron portion is continuously provided on the upper surfaces of the fixed beam and the moving beam. A V-shaped groove-shaped material support is formed between adjacent chevron-shaped parts, and the movable beam is moved in a circular or elliptical manner by a driving device, thereby rotating the material and transferring the next material from the material support of the fixed beam. It is an object of the present invention to provide a device for transferring material to a support.

This idea enables reliable rotational feeding of the material in a short time, prevents damage to the material by rotating it without applying excessive force, and furthermore, the rotational feeding operation of the material can be carried out using a moving beam. The purpose of this is to simplify the structure and reduce costs by providing only the motion of the motor.

This invention will be explained below with reference to the attached drawings which are one embodiment.

In the figure, 1 is a fixed beam, 2 is a moving beam, and a plurality of both beams 1 and 2 are arranged horizontally in parallel. The plurality of fixed beams 1 are fixed to a fixed support 4 via fixed beam receivers 3, and the fixed support 4 is fixed to a base 5. The plurality of moving beams 2 are connected to a moving support 7 via a moving beam receiver 6.
Roller supports 22, 22 having rotating rollers 23 are provided on the lower surface of the movable support 7.

On the upper surface of the fixed beam 1, substantially serrated chevron-shaped portions 8 are provided continuously in the longitudinal direction, and V-shaped material support portions 9 are formed between adjacent chevron-shaped portions 8. The chevron-shaped portion 8 has a right-angled triangular shape, and the right-angled apex 10 is cut off as shown in FIG. This cut allows the top portion 10 to be located within the circular motion locus of the moving beam 2, which will be described later.

On the other hand, substantially serrated chevron-shaped portions 11 are provided on the upper surface of the movable beam 2 continuously in the longitudinal direction, similar to the fixed beam 1, and a V-shaped material is transferred between adjacent chevron-shaped portions 11. A section 12 is configured. The chevron-shaped portion 11 has a right-angled triangular shape, with a right-angled apex 1
3 is formed in an arc shape. Then, the distance L ₁ between adjacent material transfer parts 12 of the moving beam 2
is equal to the distance L ₂ between adjacent material supports 9 of the fixed beam 1. Further, the chevron-shaped portions 8 and 11 are triangular in shape and tilted forward.

As shown in FIG. 3, the moving beam 2 has a horizontal line connecting the lower end point P 1 of the material support section 9 of the fixed beam ₁ and the lower end point P _{2 of the material transfer section 12 of the moving beam 2} .
The moving beam 2 rotates counterclockwise in the figure with a radius R around an intersection point P ₃ with a perpendicular line from , and the lower end point P ₂ of the moving beam 2 traces a circular motion locus 15 . During the upward stroke of the moving beam 2 due to this circular motion, the chevron-shaped top 13 of the moving beam 2 intersects the material support portion 9 of the fixed beam 1, and further the material support portion 9
As the material 14 rises further upward, the top 13 of the movable beam 2 lifts one end of the lower surface 14a of the material 14 placed on the material support portion 9 of the fixed beam 1, and rotates the material 14 using the other end of the lower surface 14a as a fulcrum. When the material transfer lower end point P ₂ of the moving beam 2 intersects the material support part 9 of the fixed beam 1 and further rises above the material support part 9, this rise causes the material 14 to
The material is transferred from the material support section 9 of the fixed beam 1 to the material transfer section 12 of the movable beam 2 while being rotated by .degree.
Due to the circular movement of the moving beam 2, the transferred material 14 moves to the lower end point _P2 of the material transfer section 12 on a circular movement locus 15.
When the lower end point _P2 of the material transfer section 12 passes through the uppermost point T, the material 14 is lowered. At this time, since the top 10 of the chevron-shaped portion of the fixed beam 1 is cut and positioned within the circular motion locus 15, the material 14 does not come into contact with the top 10 of the chevron-shaped portion of the fixed beam 1, and descends. .

The lower end point _P2 of the material transfer section 12 of the moving beam 2 rotates so that the material support section 9 of the fixed beam 1 rotates on the horizontal line L.
When the material 14 intersects the lower end point P ₁ of the moving beam 2, the material 14 is transferred from the material transfer section 12 of the moving beam 2 to the next material support section 9 of the fixed beam 1 adjacent to the front on the conveyance side.

In order to move the moving beam 2 in a circular motion, the first
As shown in FIG. 2, a motor 16 is provided at a lateral intermediate portion of the moving beam 2, and the drive shaft of the motor 16 is connected to an intermediate shaft 18 provided parallel to the moving beam 2 via a speed reducer 17. , 18. The intermediate shaft 18 is connected via reduction gears 20, 20 to drive shafts 19, 19, which are provided below the moving beam 2 and in orthogonal directions. is provided. A rotating roller 23 of a roller support base 22 provided on the lower surface of the movable support 7 is in contact with the upper surface of the eccentric shaft 21 . The eccentric shaft 21 is rotated by the drive of the motor 16, and this rotation causes the moving beam 2 to rotate in the direction of the arrow 24 in FIG.

Next, the operation of the material transfer device having the above configuration will be explained.

First, a prismatic material 14 with a square cross section is fixed with its longitudinal direction, positioned in a direction perpendicular to the longitudinal direction of the moving beams 1 and 2, and placed and supplied to the material support section 9 behind the fixed beam 1 in the conveyance direction. . At this time,
The chevron-shaped top portion 13 of the movable beam 2 is located near the bottom of the material support portion 9 of the fixed beam 1.

Next, the drive shaft 19 is rotated by starting the motor 16, and this rotation causes the moving beam 2 to move circularly in the direction of the arrow 24 in FIG. Due to this circular movement of the moving beam 2, the material 14 is moved by 90° as described above.
゜ Fixed beam 1 adjacent in the conveying direction while rotating
The material is transferred to the material support section 9 of. Above moving beam 2
Each time the circular motion of the material 14 rotates once, the material 14 is rotated by 90 degrees, sequentially transferred to the material support portion 9 of the fixed beam 1, and rotated in the conveying direction. Due to this rotational transfer, the material 14 is alternately supported by the material support section 9 of the fixed beam 1 and the material transfer section 12 of the movable beam 2, and the supported surface of the material 14 is sequentially displaced. Due to this displacement, the bending in the longitudinal direction that originally occurred in the material 14 is gradually reduced by the weight of the material 14, and each surface of the material 14 is evenly cooled by a cooling means (not shown). As a result, cooling time is short and
In addition, bending of the material 14 due to temperature differences is also reduced.

In the above embodiment, the cross-sectional shape of the material is a square prism, but it is not limited to this, and it may be circular or rectangular, and the moving beam 2 may be driven in an ellipse.

As is clear from the above explanation, according to the device of the present invention, the material can be reliably rotated and transferred by the circular or elliptical motion of the moving beam, and even if the material is curved in the longitudinal direction, it can be transferred smoothly. It can be transferred while being corrected. In addition, since the moving beam is simply moved in a circular motion, the structure is extremely simple and can be manufactured at low cost, and there is little contact surface with the material during rotation, and no excessive force is applied, so there is no possibility of scratches. In addition, each surface can be uniformly cooled while rotating and transferring the material, and quality can be improved.
