Abstract

PURPOSE:To automatically carry out a steel plate piling-up process including the step of removing defective steel plates to aim at speeding up the piling process, by lifting up a steel plate conveyed on a conveyor table with the use of electromagnets so that the thus lifted-up steel plate is piled on a steel plate which is introduced. CONSTITUTION:A steel plate piling-up device 10 lowers a movable beam 14 by means of wind-up motors 13 so that electromagnets 15 attract a steel plate 20 conveyed on a conveyor table 16, and then elevates the movable beam 14 to lift up the steel plate. Then the lifted-up steel plate is lowered and piled on a succeeding steel plate 21 which is introduced into the device 10, and the thus two steel plates 20 are lifted up together to enable a third steel to be introduced. The similar steps as mentioned above are thereafter repeated to pile up a plurality of steel plates. In this arrangement there is provided a data processor 31 which receives data concerning whether each steel plate is defective or not, and so forth, from a computer 30 and issues a control signal. However, control is made to allow a steel plate to pass while a preceding steel plate is left to be lifted up when no piling-up is carried out or the steel plate is fed forward.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to an automatic steel plate pile device that stacks a plurality of steel plates, particularly thick plates, conveyed from an upstream side and carries them out to a downstream side.

Conventional technology and problems The plate finishing process consists of inspection processes, shot blasting processes, care processes, painting processes, shipping processes, etc. Unlike the rolling process, there are many lines and logistics management is complicated. In addition, there are many overhead cranes, piling cranes, etc. in the finishing process, and these are important for logistics management. A piling crane is used for moving to and from other areas, and the operating rate of this crane is high during the finishing process.

Cranes are mainly controlled manually by operators, making automation difficult. However, automation is essential to speed up processing. For example, in the ultrasonic flaw detection line used in the finishing process, the flaw detector can detect four steel plates in a few seconds per sheet, but manually operated pile/ring cranes cannot perform pile operations in such a short time. ,
The piling crane controls the speed of the flaw detection line and becomes a bottleneck for the line. The reason why the manually operated piling crane has a long operating cycle is that when it comes to piling, it is determined whether or not the transported steel plate can be piled. This is because it requires processing such as deciding whether to However, if this is to be processed automatically, a time cycle is possible.

There are restrictions on the steel materials that can be piled using a piling crane, such as those that are of the same type and those that have passed inspection results. It's not good. In automation, the selection of materials to be piled and the processing method for non-target materials are important.

OBJECTS OF THE INVENTION The present invention aims to solve the above problems, automate the piling crane, that is, the steel plate piling device, and increase the speed of the steel plate conveyance line.

Structure of the Invention The present invention provides a steel plate that is installed on a conveying table, lifts up each group of electromagnets that are conveyed through the table, and stacks the steel plates downwardly on top of the steel plate that has been brought in, so that a predetermined number of steel plates are stacked. In the steel plate pile device that carries out the steel plate using the table, 1. Receiving the steel plate information by computer, such as whether the steel plate that is being conveyed is the material to be piled or whether it has passed the inspection, and whether it is "C pile completed, pile execution, forward" or not. A data processing device that generates control signals such as If the steel plate is lifted by a group of electromagnets set to a predetermined current value, the steel plate is brought in, and then the lifted steel plate is lowered onto the steel plate. The present invention is characterized in that it includes a control device for controlling the steel plate to pass through the pile device after being lifted by the steel plate.Next, this will be explained in detail with reference to Examples.

Reference numeral 17 is a running love, 18 is a running motor, and the hoisting electric motor 13 and the like are attached to the running love. Reference numeral 19 designates a conveyor table, 16 a drive motor, and 22 a steel plate detector. 1st
The above-mentioned ultrasonic flaw detector is located on the right side of the steel plate pile device 10 in the figure, and the detected steel plates are piled up in the pile device 10, and the stacked steel plates are sent to the left side of the figure 1, and then the paper It is sent vertically to the shipping yard.

Steel plate pile conditions include the material to be piled, pile type, inspection results, etc. Some rope wedges do not pile and are excluded from piles. Also, there are restrictions on the number of items that can be piled, such as up to 3 items, up to 5 items, etc., so they are divided into classes such as A type, type 0, and type 0, and items that can be piled are of the same type. The check item is whether they are from the same lot. In addition, items with poor inspection results are not piled even if they are of a type that is OK to pile, are passed through the pile device, and are followed by a detailed inspection process by the inspector, which is connected to the square line perpendicular to the page. carry it to

The various factors mentioned above regarding whether or not each steel plate can be piled are registered in the memory of the computer system, and managed (tracked) in correspondence with the current position of each steel plate, and the pile equipment 1
0 is controlled according to this information, and the conveyed steel plate is piled or not piled and sent out as is.

FIG. 3 shows the control system of the steel plate pile device 109, where 3O is a process management computer, 31 is a data processing device for the piling machine, that is, the automatic steel plate pile device 10, 32 is a control device for the piling machine, and 33 is a transfer table control device. . The information on the opening and throat of the steel plate, the test results, etc. are sent to the data processing device 31 via the process control machine 30, which determines whether piles can be piled or not, and issues commands to the control devices 32 and 33.

When piling with the steel plate pile device 10, the steel plate 20 in this example that has been transported directly under the lifting electromagnet 15 is attracted to the electromagnet 15 by lowering the beam 14, and the vinyl 14 is hoisted by the electric motor 13 from Therefore, lift the steel plate 20 adsorbed to it, and in this state move on to the next steel plate 2.
1 is carried into the pile device 10, and then the beam 14 is lowered and the steel plate 20 is placed on the steel plate 21. In this way steel plate 2
Piling of sheets is performed. For the third sheet, lift the two sheets together, carry the third sheet into the pile device, and lift it up f2.
This is done by lowering the third steel plate. The same applies below. If the steel plate is not piled due to a poor inspection result, if there is a steel plate in the pile device, the steel plate is attracted to the electromagnet 15, the beam 14 is lifted, and in this state, the roller i6 is driven until it rises to the conveying table roller 16.

The diagram shows the flow chart. FIG. 5 shows a six-file procedure, in which the aforementioned product data processing device 31 receives data regarding the next steel plate (21 in FIG. 1) from the process control calculation machine 30, and first checks 7 whether or not the steel plate is a material to be piled. I will If the material is not to be piled (N), the pile end operation is instructed, and the pile device 1
The steel plate in 0 is driven together with the conveyance roller 16 on which the plate 21 is placed. Therefore, the steel sheet in the pile device is discharged from the pile device, and the next steel sheet enters the pile device. What to do in this case! The area is shown in Figure 4+al. For materials to be piled (Y)
Next, check whether the materials are from the same lot.

Here, the same lot material refers to the type of material that can be stacked on the steel plates in the pile device, and the first steel plates to be piled are of the same loft material. If the materials are not from the same lot, the pile end operation is instructed, the steel plate is discharged from the pile device as described above, and the next steel plate is carried into the pile device. If the materials are from the same two lots, the next step is to check whether they pass the inspection, and if they fail (N), they are instructed to move forward (pass through the pile device). The processing procedure in this case is shown in FIG. 4(b). If it passes (Y), check whether the target steel plate is too heavy or too long for installation inside the pile device,
If YES (Y), a pile binding operation is instructed, and if 1-(N), a pile execution is instructed. In other words, the steel plates to be piled must be pile target materials, be from the same lot, pass inspection, and not be too long or overloaded.
Otherwise, the pile ends or postpones. Figure 6(b) shows the □ pile procedure.

Figure 146 □(a) □ is a flowchart following the 4th mcb+.

Five zeros pile up. When there is no steel plate in the pipe JLt device and two steel plates are transported in this state, the process i1 is as follows.

That is, first, the first steel plate is detected and the following judgments are made: ■ There is a steel plate in the pile device (NO) ■ Is the steel plate the material to be piled (YES) ■ Does it pass the inspection (YES)? ■ Dimensional abnormality (No) When the result in parentheses is obtained, enter the pile execution mode and traverse the 61st steel plate. Perform beam settings. Next, the second steel plate is detected and the following judgments are made: ■ Is there a steel plate in the pile device? (YES) 0 ■ Is the steel plate a material to be piled (YES)? ■ Does the inspection result pass (YES)? ■ Abnormal dimensions (No) When the result in parentheses is obtained, the system enters the pile execution mode, and if the next judgment is YES (1 steel plate present), the lifting electromagnet current is set, the first steel plate is lifted, the second steel plate is carried into the pile device, Waiting for the first steel.

If the inspection result of the 2nd sheet-plate fails, the mode will be postponed and the 5th judgment will be made. ■ If the first steel plate is present is YES, the hanging electromagnet current setting, the first steel plate will be raised, and the second steel plate will be checked. Passing through the pile device, hanging the first steel plate onto the conveyor tape, or not, waiting for the next material to be conveyed.

Each of these operations is performed by the data processing device 31 in FIG. 3 generating command signals to the control device 3.2.33. To summarize the functions of these devices, those of the data processing device 31 are: ■Table racking, ■Front-filling automatic conveyance control, ■Pile execution, end of pile, determination of advance mode, ■Addition of number of pile sheets, ■Table stop position calculation, ■Pile execution status monitoring. The functions of the piling machine control device 32 are: ■ Selection of the number of lifting electromagnets, ■ Current calculation of the electromagnets, ■ Calculation of beam traverse position, ■ Steel plate lifting management (sequence control), and the functions of the conveyance table control device 33 are: These are speed control for each table, and (1) length needle error correction calculation.

In the piling machine control device 32, the data processing device 31
When a command signal is received from the motor 13, the motor 13 is driven to move the movable beam 14 up and down, and the excitation current of the electromagnet 15 is set, energized, and deenergized. The excitation current of the electromagnet 15 is different depending on, for example, when lifting one steel plate and when lifting two steel plates, so it is changed depending on the number of plates to be lifted. Also, which of the many electromagnets is energized and which is not energized is selected depending on the dimensions of the steel plate to be lifted. When controlling the steel plate pile device manually, it takes time to look at the data and make these selections and settings. With automatic setting, the required time is very short and the period can be made small.Since the electromagnet has a large inductance, when a constant electric current is applied, the current rises slowly and reaches a constant value. It takes time to reach this point.In this regard, it is possible to take measures such as energizing an electromagnetic front right constant current source to hasten the rise of the rain hat and shorten the front cycle.

When performing a pie motion with a pie device, it is important that the electromagnet securely lifts and raises the steel plate before bringing in the next steel plate. If the next steel plate is brought in with the steel plate not lifted or fully lifted, it will collide and cause damage to the front. There is a risk of destroying process facilities and ultrasonic flaw detection equipment. For this purpose, the steel plate detector 22 and the like are used to detect one plate on the roll 16 and to control the steel plate position and conveyance.
Outputs a signal. . Whether or not the electromagnet has reliably lifted a plate is detected by an i-plate detector (not shown) and a change in the excitation current of the electric stone.

Effect of the invention.

3. As explained above, according to the present invention, pies and nori are installed on the conveyance line. Since the equipment has been automated, it is possible to increase the steel plate feeding rate of the conveyance line and improve productivity. Moreover, it is possible to appropriately process steel plates that do not pile up, and there is an advantage that distribution is not hindered by the presence of non-piled materials.
