Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for transversely feeding a steel billet such as a round steel billet from one conveyance line to another by shifting it in a direction orthogonal to the conveyance direction.

In the case of rolling equipment for steel billets, for example, as shown in FIG. Another conveyance line consisting of roller tables 4 is arranged in two rows with a traversing device 5 at each end. This is to make effective use of the limited area within the building. Then, the steel billet, which is the material to be rolled, rolled in the rolling mill 1 is conveyed by the roller table 2, then shifted and fed laterally by the traversing device 5, sent to another roller table 4, and further transported.

Now, here, the conventional transverse feed device and the like are as shown in FIG. That is, this feeding device includes a truck 7 with a dog 6, a fixed guide rail 8 for the truck 7, and a traction mechanism 9 for the truck 7. A falls off and falls to both sides, and trolley 7
In order to prevent it from hitting the skid beam, etc., a fixed guide 1 is installed on the side opposite to the roller table 4.
0, lifting mechanism 11 on the side of the roller table 4 side
An elevating guide 12 that is moved up and down by a was provided.

However, the following problems have been pointed out in this conventional example. In other words, first
Furthermore, when the truck 7 retreats toward the roller table 2, the dog 6 may collide with the steel piece A. Second, since the fixed guide 10, the lifting mechanism 11, the lifting guide 12, etc. are required as incidental equipment, the overall structure becomes complicated, failures are likely to occur, and the equipment cost becomes high. In particular, when the length of the steel billet A, which is a rolled product, becomes long, such as 100 m, the support mechanism for the lifting guide 12 becomes complicated and large-scale, and its installation may become extremely difficult.

In view of these circumstances, the present invention has been developed to solve the above-mentioned problems of the conventional example, and includes a shift cart that moves on a guide rail that can be raised and lowered and is provided with a predetermined protrusion. It is an object of the present invention to propose a transverse feeding device for steel billets in which the shift cart does not collide with the steel billets and the incidental equipment is simplified.

The present invention will be explained below based on the embodiments shown in the drawings from FIG. 3 onwards.

First, the basic configuration that characterizes the present invention will be explained.

This steel billet lateral feeding device relates to a device for transversely feeding a steel billet A from a conveyance line such as a certain roller table 2 to a conveyance line such as another roller table 4. A guide rail 14 is disposed between the conveyor lines such as between the roller table 2 and the roller table 4, and is movable up and down by an elevating mechanism 13.
The shift cart 17 is provided with protrusions 16, 16 facing each other on its upper surface ₁₇₁ with an interval sufficiently longer than the width of the steel piece A.

Next, the details of the configuration of this traversing device will be explained.

The guide rail 14 connects the end of a roller table 2, which is a certain conveyance line, and this roller table 2.
and the end of the roller table 4, which is another conveyance line, which is arranged in parallel at the same height level.
It is arranged in a direction perpendicular to these.

This guide rail 14 is raised and lowered by the raising and lowering mechanism 13. This elevating mechanism 13 includes a crankshaft 18 held at a predetermined height, and a crankshaft 18 held at a predetermined height.
Bell crank arm 19 whose central part is pivotally supported by 8
The upper end 20 of this bell crank arm 19 pivotally supports one end 21 of the guide rail 14 via a pin 22, and the lower end 23 of this bell crank arm 19 is pivotally supported on a stationary part. The piston rod is pivotally connected to the tip of the piston rod of an electric or hydraulic cylinder 24 which is a driving source. Also, lifting mechanism 13
In this case, the upper end 25 is connected to the other end 26 of the guide rail 14.
is pivotally supported via a pin 27, and the lower end portion 28
has a crank arm 30 which is pivotally supported by a crankshaft 29 held at the same height level as the crankshaft 18.

This crank arm 30 is connected to the guide rail 14
It follows the movement of the bell crank arm 19 via.

The operation of this lifting mechanism 13 will be explained with reference to Fig. 5. When the tip of the piston rod of the cylinder 24 advances from point a' to point b', the bell crank arm 1
As the upper end 20 of the bell crank arm 19 also rotates from point a to point b, the guide rail 14 rises by the vertical movement amount h/2. Next, when the piston rod of the cylinder 24 is retracted from point b' to point o, the upper end 20 rotates from point b to point o, and the guide rail 14 descends by an amount h. If the clockwise rotation angle from point b is θ, for example _θ1 , _θ2 , and the length from the crankshaft 18 of the bell crank arm 19 to the end of the upper end 20 is R, the vertical movement amount of the guide rail 14 is expressed as R(1-cosθ), so that the distance between b-a and between b-o can be expressed as any angle _θ1 , _θ2.
etc., the maximum height position, neutral position, and minimum height position of the guide rail 14 can be freely selected.

The shift cart 17 running on this guide rail 14 is equipped with wheels 31 at the bottom, and
Opposing protrusions 16, 16 are provided at the front and rear of the upper surface ₁₇₁ . This protrusion 16 has an inclined surface formed toward the opposing inner side.

The drive mechanism 15 that pulls and runs the shift cart 17 is a chain wheel or a grooved drum (hereinafter referred to as a drum) disposed on the outside of one end 21 and the other end 26 of the guide rail 14, respectively.
33, a chain wheel or grooved wheel (hereinafter referred to as a wheel) 32, a motor, a speed reducer, etc. (not shown) for rotating this drum 33, and a rope stretched between this drum 33 and the wheel 32; It consists of a tension rod 34 such as a wire or chain, and one end 35 of this tension rod 34 connects to the shift cart 17.
, the other end 36 is at the rear of the shift truck 17,
Each is connected.

The steel billet lateral feeding device according to the present invention is configured as described above.

Next, its operation will be explained.

For example, a steel billet A, which is a material to be rolled, is conveyed on a conveyance line with a roller table 2 or the like, and stops at a predetermined position at its terminal end. The relationship between the roller table 2 and the shift cart 17 at this time is shown in FIG.
As shown, the upper surface ₁₇ of the shift truck 17
is located at a position slightly lower than the upper surface ₂₁ of the roller table 2, so the steel piece A is placed on the roller table 2. That is, the guide rail 14 is at the height of a predetermined neutral position. In this case, the protrusions 16, 16 of the shift cart 17 are in a state of protruding higher than the upper surface ₂₁ of the roller table 2, so they function as a guide and prevent the steel piece A from falling off or falling from the roller table 2 during transportation etc. Accidents that occur will be definitely prevented.

Next, by operating the elevating mechanism 13, the guide rail 14 and the shift truck 17 are raised to their highest height positions, and the relationship between the roller table 2 and the shift truck 17 becomes as shown in FIG. 62.

That is, since the top surface 17 ₁ of the shift cart 17 is located higher than the top surface 2 ₁ of the roller table 2,
The steel piece A is moved from the roller table 2 to the shift trolley 1.
Transferred to 7.

Thereafter, the drive mechanism 15 is activated, and the shift cart 17 on which the steel piece A is placed is moved forward from the roller table 2 side to the roller table 4 side (third
(see figure). In this way, the steel billet A is transversely fed in a direction perpendicular to the conveyance direction of the roller table 2. At this time, the protrusion 16 functions as a dog that pushes the steel piece A, and also functions as a guide to prevent it from falling off or falling.

When the shift truck 17 reaches the position of the roller table 4, the drive mechanism 15 is stopped to stop the movement of the shift truck 17, and the lifting mechanism 13 is activated to lower the guide rail 14 and the shift truck 17.
As shown in FIG. 6, the upper end of the protrusion 16 stops at the lowest height position below the upper surface ₄₁ of the roller table 4. As a result, the steel piece A is placed on the roller table 4 from the shift cart 17.

Next, the drive mechanism 15 operates again, and the shift truck 1
7 is moved backward and returned to the position of the roller table 2. At this time, the protrusion 16 of the shift cart 17
Since the upper end is lower than the upper surface ₂₁ of the roller table 2, the situation where the next steel piece A placed and conveyed on the roller table 2 collides with this shift cart 17, especially its protrusion 16, will be avoided. This is definitely prevented.

Then, the shift truck 17 is raised by the lifting mechanism 13 to the neutral position shown in FIG. 6.

This lateral feed device repeats this operation,
The steel pieces A are successively fed laterally from the roller table 2 to the roller table 4.

As explained above, the steel billet lateral feeding device according to the present invention is equipped with a shift cart that moves on a guide rail that can be raised and lowered and is provided with a predetermined protrusion, so that the shift cart can be moved to the appropriate minimum height position. Because of this, it is possible to reliably prevent collisions with the steel pieces being conveyed by the conveyor line, and the protrusions function as guides to prevent the steel pieces conveyed by the conveyor line from falling. Fixed guides, lifting guides, lifting mechanisms, etc.
It does not require incidental equipment such as a support mechanism, the mechanism is simple, the operation is reliable, the equipment cost is low, and the problems that existed in conventional examples of this type are eliminated. There is something remarkable and great about it.
