Abstract

PROBLEM TO BE SOLVED: To surely and automatically charge a saw-cut product into a cooling bed by simultaneously carrying a rod steel at the predecided interval between the tail end part and the front end part of adjacent saw-cut products after saw-cutting the rod steel and stopping the front end part of the forefront saw-cut product at the predecided stopping position. SOLUTION: On a table faced to an equipment, two pieces of saw-cut products are treated such as one piece of material, and while keeping the interval between both pieces, these pieces are automatically stopped at the pre- decided stopping position of the product on the downstream side. In such a way, at the point of stopping time, since the front end part and the rear end part of both products on the upstream side and on the downstream side can have the suitable positional relation with just near the carriage 18, these products are laid on the carriages 18 as they are. At the time of charging onto the cooling bed by shifting these carriages 18 in the orthogonal direction to the carrying direction, it can surely be prevented that these carriages 18 are derailed from the shifting rails and also, the filling ratio of the products can always be sufficient.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a plurality of sawing products obtained by hot-cutting a bar steel product such as an H-section steel, a sheet pile or a billet. The present invention relates to a method and an apparatus for automatically installing a cooling floor for sawing products, which are preferably applied when the cooling floor is charged by a carriage.

[0002]

2. Description of the Related Art Generally, strip steel products such as H-section steel, sheet pile or billet are rolled by a rolling mill 10 and then cut by a sawing machine 12 as schematically shown in FIG. Is then cut into a plurality of pieces having a predetermined length, and then conveyed to a cooling bed (cooling floor) 14 by a conveying table (table roll), and charged into the cooling bed 14 for cooling.

FIG. 12 shows an outline of charging equipment installed on the entrance side of the cooling bed 14. For convenience, here, a case of a double-size product in which one steel bar is cut into two saw products will be described.

[0004] The two products sawn by the sawing equipment 12 are placed in a table roll 1 at a position (A) in the figure.
The stop is controlled to the charging position on the cooling bed entrance side by the table transfer by 6. Thereafter, these products are separated at intervals in the transport direction (table transport direction indicated by the arrow) of the cooling bed (CB) by the ascending operation of the loading equipment (CB entry transfer in the figure). After being placed on a plurality of carriages (carts) 18 arranged orthogonally in the same direction, the cooling bed is traversed in a direction orthogonal to the table transfer direction (indicated as a traverse in the figure) to move the cooling bed. After being sent downstream (toward the CB exit side), the carriage 18 is erected at the position (B) in the figure to change the loading posture of the product 90 ° from horizontal to vertical, and then at the position (C). By lowering the equipment at a traversing position that is at a predetermined distance from other products already loaded as shown, a series of cooling bed loading operations is completed.

[0005] As described above, when the charging operation by the cooling bed charging equipment is completed, the walking beam (indicated by CBWB in the figure) in the cooling bed repeats a series of operations of ascending, advancing, descending, and retreating. This allows the product to be transported to the cooling bed exit side while cooling.

In the cooling bed charging equipment, each carriage 18 constituting the charging means is structured to run on a traversing rail (not shown), and the entire rail is raised and lowered. Thus, the sawed product can be raised and lowered as described above.
At this time, the control of the traversing operation is performed by transmitting the rotation of a drive shaft (not shown) to each carriage 18 on the table by a chain. Therefore, this equipment has a structural feature that the restraint of each carriage 18 in the thrust direction (the direction of transporting the product) is weak.

When carrying out the work of loading the cooling bed with such a facility, after raising the product on the carriage 18, or when the loading posture is changed by 90 ° by raising the carriage 18, etc. At the portion where the product end contacts the carriage 18, a moment in the direction of the arrow as shown in FIG. 13 is applied, and as a result, the trouble that the carriage 18 derails on the traversing rail is likely to occur.

In order to avoid this, the stop position of the table roll 16 for transporting the sawed product so that the operator does not touch the product while checking the length of the sawed product and the positional relationship between the carriages is conventionally viewed by an operator. Was going to decide.

Conventionally, in order to automate the charging operation while avoiding the above-mentioned troubles in such a cooling bed charging equipment, the cooling bed entrance side table is divided into two sections, an upstream side and a downstream side. Divide and 2
A method has been used in which a plurality of saw products are transported one by one to a table, and are stopped at their respective optimal stopping positions and charged.

[0010] Further, even when two products are transported simultaneously, these two products may be located in the middle of the table leading to the cooling bed.
A method has been used in which the product of the book is divided and controlled so that the stop control is individually performed for the upstream product and the downstream product.

[0011]

However, in order to automate the work of loading the cooling bed, when the above-mentioned conventional method of transporting the two products after cutting into a table one by one is adopted, the cutting method is difficult. Since the residence time of the product in the cutting line including the equipment becomes longer, the waiting time for the next cut product becomes longer, and there is a problem that the processing capacity of the cutting line is reduced.

In the case of employing the above-described method of simultaneous transport division control, the time required for the two products to stop on the table on the entrance side of the cooling bed becomes long. However, there is a problem that the processing capacity of the device is reduced.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional problems, and a cutting machine capable of surely automatically loading a cutting product into a cooling bed without lowering the processing capacity of a cutting line. An object of the present invention is to provide a method and an apparatus for automatically charging a cooling floor of a product.

[0014]

SUMMARY OF THE INVENTION The present invention is directed to a method for sawing a steel bar into a plurality of products of a predetermined length, and then cutting each of the cut products along the longitudinal direction of the product on the downstream side of the cooling bed. Simultaneously transported to the charging equipment arranged in the, after stopping at a predetermined position, the stopped sawed products, the charging equipment has, spaced in the transport direction, perpendicular to the same direction A plurality of carriages arranged in a row, the carriage is moved in a direction perpendicular to the transport direction, and the automatic cooling floor loading method for the sawing products loaded on the cooling floor is performed. Assuming a case where the products are arranged in the cutting direction in the longitudinal direction and transported to the loading equipment, for each of the cutting products from the earliest to the final, each of the leading end and the tail end, with respect to the nearest carriage, To prevent the carriage from entering the danger area where derailment may occur, The stop position of the sawed product, and the respective intervals between the front end of each succeeding sawed product and the tail end of the forwardly adjacent sawed product are determined in advance, and after cutting the bar steel, , And simultaneously conveyed by the transfer table at the predetermined intervals between the tail end and the tip of each adjacent saw product, and the tip of the earliest saw product is stopped at the predetermined stop. This problem has been solved by stopping the motor so as to match the position.

[0015] The present invention also provides a sawing facility for sawing a steel bar into a plurality of products of a predetermined length, and distributing each of the sawed products along the longitudinal direction to an inlet side of a downstream cooling bed. Transport means for simultaneously transporting to the installed charging equipment and stopping at a predetermined position,
The stopped sawed products are placed on a plurality of carriages, which are arranged at right angles to each other in the carrying direction and are arranged perpendicularly to each other in the carrying direction, and the carriages are perpendicular to the carrying direction. In the automatic cooling floor loading apparatus for sawing products provided with charging means for charging the cooling floor by moving the sawing products in the longitudinal direction in the sawing order and transporting them to the charging facility. Assuming the case where the carriage is stopped, the leading end and the tail end of each of the cut products from the earliest to the last are within the danger range where the carriage may derail with respect to the nearest carriage. Calculation means for determining in advance the stop position of the earliest saw product and the respective intervals between the leading end of each succeeding saw product and the tail end of the forwardly adjacent saw product, so as not to enter. And after cutting the bar, the tail end of each adjacent cut product Table control means for simultaneously transporting by the transport table with the predetermined intervals between the leading end and the leading edge of the earliest saw product stopped so as to match the predetermined stopping position; With the provision of the above, the above-mentioned problem is solved similarly.

[0016]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram corresponding to FIG. 11 showing a schematic configuration of an automatic cooling floor charging apparatus according to an embodiment of the present invention.

The automatic charging device of this embodiment is the same as that of FIG.
1. The basic equipment configuration is the same as that of the die steel mill described with reference to FIG. 12, and a sawing equipment for converting a steel bar rolled by the rolling mill 10 into two products of a predetermined length downstream and upstream. 12
A transport table (table roll) 16 for simultaneously transporting each of these cut products along the longitudinal direction to the inlet side of the cooling floor 14 on the downstream side and stopping at a predetermined position. The carriage 18 is placed on a plurality of carriages 18 arranged on the entrance side of the cooling floor 14 and arranged at right angles to the conveyance direction at intervals in the conveyance direction, and the carriages 18 are moved in a direction perpendicular to the conveyance direction. And a charging unit similar to that shown in FIG. 12 described above, having charging means for charging the cooling floor 14.

Here, a hot-saw strip steel product such as an H-section steel, a sheet pile, a billet, etc. is taken as a double-size product, cut into two pieces of a predetermined product length, and these two products are simultaneously cut. The cooling bed is moved up and down and traversed by loading and unloading equipment comprising a plurality of carriages arranged on the entrance side of a cooling bed (cooling floor), which is arranged on a cooling bed (cooling floor) and arranged orthogonally to the carrying direction. The case of charging into a container will be described as a specific example.

In this embodiment, the operation of the entire equipment is controlled by a control device 20 composed of a host computer, and a control signal from the control device 20 is input to a table control device 22, The control device 22 controls the drive of the transfer table 16 constituting a sawing line for transferring the sawed product from the sawing equipment 12 to the cooling floor 14.

In the present embodiment, the control device (arithmetic means) 20 arranges the cut products in the cutting order, that is, the downstream products and then the upstream products in the longitudinal direction, conveys the cut products to the charging equipment, and stops. Assuming a case where the carriage 18 is located, the leading end and the trailing end of each of these products are the nearest carriages 18.
In order to prevent the carriage 18 from entering a dangerous area where the carriage 18 may derail, a stop position of the downstream product, and
It has an arithmetic function for determining in advance the distance between the leading end of the succeeding upstream product and the tail end of the downstream product (the front adjacent cutting product).

As will be described in detail later, when the stop position of the downstream product and the distance between the tail end of the downstream product and the tip of the upstream product are determined in advance, the tip of the downstream product is determined. A reference position at which the unit is stopped, based on known information such as the distance from the reference position to each carriage, the width of the carriage, the danger range preset for each carriage, and the length of each product. An operation to be automatically determined is executed.

Further, the table control device 22 cuts the bar steel and then determines a predetermined value inputted from the control device 20 between the rear end of the downstream product and the front end of the upstream product. It has a function of simultaneously transporting by the transport table 16 at the interval, and stopping the downstream product so that the leading end of the downstream product coincides with the predetermined stop position.

In the table controller 22, specifically, the simultaneous conveyance performed at the predetermined interval between the rear end of the downstream product and the front end of the upstream product is performed by sawing. The transfer is started by shifting the start timing of the transfer table on which the subsequent upstream product is loaded and the start timing of the transfer table on which the downstream product is loaded by a time difference corresponding to the same interval.

FIG. 2 is a diagram conceptually showing the features of the cooling floor automatic charging method of the present embodiment.

In the present embodiment, a downstream product (first product in the figure) located on the downstream side in the transport direction is transported simultaneously with two upstream products (second product in the figure) located on the upstream side. This is a method for automatically loading these products into the cooling bed without causing derailment of the carriage 18 of the loading facility on the cooling bed entry side.

To explain this in detail, as shown in FIG. 2, when two sawn products are simultaneously conveyed, the front end position and the tail end position of the downstream product, and the front end position and the tail end of the upstream product are transferred. Assuming a case where each of the positions is conveyed to the cooling bed charging equipment and stopped, the derailment is set in advance by comparing the positions of the carriages 18 arranged in the equipment at positions surrounded by an ellipse. The stop position of the downstream product (stop target in the figure) and
Interval between downstream product and upstream product (target between materials in the figure)
Is automatically determined in advance by the control device 20 which is a charging control computer.

Then, after actually cutting the target steel bar to the predetermined product length, the downstream product is separated by a time difference corresponding to the interval between the downstream product and the upstream product determined as described above. By delaying the start timing between the transfer by the transfer table on which the product is loaded and the transfer by the transfer table on which the product is mounted, the start of transfer of the product on the upstream side is delayed to keep the two control intervals constant. Automatic control to do.

Next, when the two cut products are actually conveyed to a cooling bed charging facility, the two products are treated as if they were a single material on a table facing the facility. The product is automatically stopped at a predetermined stop position of the downstream product while maintaining the interval between the two products.
By doing so, the leading and trailing ends of both the downstream and upstream products can be brought into an appropriate positional relationship with the nearest carriage 18 at the time of stopping, so that these two products can be used as they are. When the carriage 18 is placed on a carriage (carriage) 18 and is moved (transversely moved) in a direction perpendicular to the conveying direction and is loaded on the cooling bed, it is ensured that these carriages derail from the moving rail. This can prevent the cooling bed from lowering the product filling rate.

As described above, according to the present embodiment, two cut products at predetermined intervals are treated as if they were one material, and the cut products are set at the stop position of the downstream product. The automatic stop allows automatic conveyance from the sawing line to the cooling bed charging table and automatic charging of the cooling bed without derailing the carriage.

Next, the cooling floor automatic charging method of the present embodiment applied to a cooling bed charging line in a steel mold factory will be specifically described with reference to the flowchart of FIG.

As described above, in this embodiment, two cut products are conveyed together in a table. At this time, the stop position of the leading end of the downstream product is determined based on the positional relationship between the tail end and the carriage. The distance between the two materials is determined based on the relationship between the front end portion and the carriage and the relationship between the tail end portion and the carriage. This determination is made by the control device 20 for controlling the cooling bed charging according to the flowchart shown in FIG.

First, a preset stop reference position of the downstream product (first) is temporarily determined as a stop target position (step 1). Next, assuming that the first product is stopped at the target position, the positional relationship between the tail end portion and the nearest carriage is checked (step 2). This check is performed as follows. As shown in FIG. 4, the specifications of the cooling bed charging equipment are such that each carriage 18 is positioned at a distance L1, L2,..., L10 from an initial stop position SN which is a stop reference position of the downstream product. When the first product on the downstream side is checked, the length of the first product is checked by the following formula (1), where LD is the length, DG is the danger area where the carriage may be derailed, and W is the equipment width of the carriage. It is determined by determining whether there is a carriage that satisfies the relation of each inequality.

L1-W ≦ LD ≦ L1-W + DG L2-W ≦ LD ≦ L2-W + DG L3-W ≦ LD ≦ L3-W + DG L4-W ≦ LD ≦ L4-W + DG L5-W ≦ LD ≦ L5-W + DG L6- W ≦ LD ≦ L6-W + DG L7−W ≦ LD ≦ L7−W + DG L8−W ≦ LD ≦ L8−W + DG L9−W ≦ LD ≦ L9−W + DG L10−W ≦ LD ≦ L10−W + DG (1)

When either of the above expressions (1) is satisfied, if the first product conveyed from the right side (upstream) to the left side (downstream) in the figure is A1 shown in FIG. Since the contact is made in the danger area DG on the downstream side (left side in the figure) on the carriage 18 on the right side in the figure, it is determined that there is a possibility of derailment as shown by the mark x in the figure (NG in step 2). Then, the target stop position of the downstream product is corrected by changing by the amount SN 'obtained by the following equation (2) (step 3). In this manner, the stop target position is changed to the product position indicated by A2 in the same figure, and the correction is performed as indicated by the circle.

SN ′ = Li−W + DG−LD (2)

Here, Li represents that the inequality group of the equation (1) that satisfies the condition is the i-th equation.

After the correction of the position of the first product, which is the downstream product, is completed, then the upstream product (second product: length LU)
Are checked stepwise according to steps 4 to 7. That is, the tip position of the second product is set by the following equation (3).

TOP = LD + S0 (S0: Initially set material interval) (3)

Next, this tip position TOP is determined by the following (4).
Check whether any of the expressions is satisfied.

L1-DG≤TOP≤L1 + DG L2-DG≤TOP≤L2 + DG L3-DG≤TOP≤L3 + DG L4-DG≤TOP≤L4 + DG L5-DG≤TOP≤L5 + DG L6-DG≤TOP≤L6 + DG L7-DG≤TOP ≦ L7 + DG L8−DG ≦ TOP ≦ L8 + DG L9−DG ≦ TOP ≦ L9 + DG L10−DG ≦ TOP ≦ L10 + DG (4)

At the same time, the tail end position of the second product is set by the following equation (5).

BOT = LD + S0 + LU (5)

Then, similarly, it is checked whether or not the tail end position BOT satisfies one of the following equations (6).

L1-W-DG ≦ BOP ≦ L1-W + DG L2-W-DG ≦ BOP ≦ L2-W + DG L3-W-DG ≦ BOP ≦ L3-W + DG L4-W-DG ≦ BOP ≦ L4-W + DG L5-W -DG≤BOP≤L5-W + DG L6-W-DG≤BOP≤L6-W + DG L7-W-DG≤BOP≤L7-W + DG L8-W-DG≤BOP≤L8-W + DG L9-W-DG≤BOP≤L9 −W + DG L10−W−DG ≦ BOP ≦ L10−W + DG (6)

6 to 10 conceptually show a method of correcting the initial intermaterial setting S0 as a result of checking by the inequality groups of the above equations (4) and (6). Note that, here, B1, B2, and B3 indicate the order of changing the product position, and NG is indicated by an X mark and OK is indicated by a O mark.

FIG. 6 shows an example in which the tip of the second product is NG, the tail is NG, and the target between the materials is corrected to S0 + S1, and FIG.
When the tip of the second product is NG at the tip and OK at the tail end, an example in which the target between materials is corrected to S0 + S2. FIG. 8 shows a case where the tail end is NG after the tip correction, and finally the target between materials is S0 + S2 + S3.
FIG. 9 shows an example in which the tip of the second product is OK and the tail end is NG, and the target between materials is corrected to S0 + S4.
FIG. 10 shows an example in which the front end becomes NG after the tail end correction, and the target between the materials is finally corrected to S0 + S4 + S5, respectively.

In FIGS. 6 and 7, the result of the first check performed in step 4 of the flowchart of FIG. 3 is OK for the second product at the position indicated by B1.
In the case of (1), the target between materials is not changed. Conversely, if the result is NG, the target between materials is changed in step 5 to the position B2.

In step B2, the position B2 is
As a result of checking the tail end of the same product for the second time, the result is OK in FIGS. 6, 7 and 9, and the target between materials is determined at that position. However, in FIG. 8 and FIG. Since it is NG, it is further changed in step 7 to the position of B3.

In the second check of step 6 executed here, the tip position of the second product is set as TOP = LD + S (S: material interval after the first correction) (7), and the tail end position of the same product BOT = LD + S + LU (8) Similarly, S3 and S5 are additionally corrected in accordance with the equations (4) and (6) as shown in FIGS. In this way, the end stop position SN ′ of the downstream product finally reaches the distance S ′ between the upstream product and the downstream product.
To determine. The above processing is performed before actually cutting the steel bar.

On the other hand, in the present embodiment, the transport table of the sawing equipment can be controlled independently of the upstream table and the downstream table of the saw (saw). And the distance S ′ between the downstream product and
By starting the upstream side table with a delay corresponding to the time corresponding to the interval S ', the interval between the materials is controlled at a constant interval to execute automatic conveyance.

According to the embodiment described above, the two products downstream and upstream that have been cut by the sawing equipment can be derailed from the carriage of the equipment on the cooling bed entrance side only by carrying the table. The automatic operation from the sawing line to the cooling bed line is now possible because the two can be automatically transported simultaneously to a position where there is no gap.

As a result, the number of operating personnel involved in cooling bed lines and cooling bed charging could be significantly reduced.

Although the present invention has been specifically described above, the present invention is not limited to the above-described embodiment, and can be variously modified without departing from the gist thereof.

For example, in the above embodiment, the case where the bar steel is a double-size product is shown, but the present invention is not limited to this, and the product may be a triple-size product or more. Also, even in the case of triple-size products,
If only the first piece is first sawed and only one piece is transported, and the rest is treated as a double-size product, the above-described embodiment can be applied as it is. However, a triple-size product can be fixed with a fixed saw or a moving saw. In the case of simultaneous sawing and transporting, the present invention can be applied as long as there is equipment capable of separating the table drive between the upstream side and the downstream side of these fixed saws and moving saws.

According to the present invention described in detail above, a sawed product can be automatically charged into a cooling bed without lowering the processing capacity of a sawing line.
