Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for automatically transporting a workpiece such as a coil.

For example, coils made by winding strips produced at steel mills, etc.
A crane is used to transport materials within the workshop (hereinafter simply referred to as Yaze). i.e. truck or 7
The π coils are transported to the entrance of the yard V using wire ropes or special lifting equipment, and are then manually slung and hoisted by a crane.The worker then selects the location according to the type of coil. During processing, a method is adopted in which a predetermined coil is searched again and then left unused.

However, this transportation operation requires poor visibility from the crane room (sometimes it is difficult to see), and a large number of coils are separated by type, and in order to manage them, a worker other than the crane operator is required. It must be managed on the ground, and the slings must be handled by the workers.

It is necessary to move between a large number of coils and select a predetermined coil for slinging, which is a labor-intensive and dangerous task.

The present invention has been made in view of the above points, and it is possible to remotely control a crane in a yard R based on a predetermined program by a control device, and to control workpieces such as coils carried into a yard V by the crane. The object of the present invention is to store the workpieces classified by type in a predetermined place, store them, and manage the workpieces in the place using the control device.

The present invention will be described below based on the embodiment shown on page 1.

The figure shows an example in which the present invention is applied to coil handling in a steelworks, etc. Yer V has a processing line M that continuously performs a series of operations such as welding, annealing, and pickling 1 for each coil number.
A coil Wa is installed near the entrance of the Yar Y.
There is also a temporary storage stand 1 near the supply side of the processing line μ, and a coil storage area 2 for coils Wa and In< for each type.
n are provided respectively.

In addition, on the yard tB entrance side, there is a product coil storage area 3 for storing the product coils wb sent out from the processing line U by type, and a temporary storage stand 4 for transporting them by a 7-o-lift or the like. is provided.

A plurality of the above-mentioned temporary storage tables 1.4 are provided as necessary, and each temporary storage table 1.4 is provided with a detector 5.6 such as a Mitsutwitch (for example, +) in order to determine the presence or absence of a coil. It is being The stiffness detectors 5 and 6 are respectively connected to a loading crane control device 13 and a loading crane control device 14, which will be described later.

A loading crane 7 and an unloading crane 8 are installed on the supply side and unloading side of the processing line U, respectively, and a coil W is installed in each lane.

It is equipped with gripping claws 9.107/ for gripping.

In addition, in the operation room provided at the appropriate location, there are lane control devices 13 and 14 on both sides of the south entrance that operate the respective cranes 7 and 8 mentioned above.

A host control device 12 is provided to control the crane 7.
．． 8, each lane control device 7f 13
, 14 using a guided radio system.

As shown in 2.
It consists of a management control section 15, a crane control section 16, and a guidance radio transmission section 17. The yard management control unit 15 deciphers the type of the coil Wa from the number, operates a carry-in crane, classifies it by type, and transports it to the coil storage area 2, and stores the coil Wa by type. In this way, inventory management is performed, and a transport command is applied to the noisy lane control section 16 to be sent to a predetermined coil 91aG"e" based on a command from the upper control table N12.

The lane controlling section 16 is equipped with a coil number display panel 18 for displaying the type or number of the conveying coil Wa and a coil confirmation operation panel 19, which are provided near the supply side of the processing line M.

In the figure, 20 is a printer, 21 is an automatic setting panel for switching to automatic operation, and 22 is a guide line.

The loading crane 7 is equipped with a guidance radio receiver 25, an interface panel 26, and a crane operation WJ 27. A coil measurement sensor 28 is installed on the interface panel 26.
, a proximity switch 29 , a position detection sensor 30 , an insert detection sensor 31 , and the like. The coil measurement sensor 28 is composed of means for detecting the outer diameter, width, and weight of the coil Wa, and the numerical values measured by the measurement sensor 28 are physically backed to the carry-in crane control device W13. This allows the actual lifted coil to be compared with the expected coil number.

The crane operating section 27 selectively operates the traveling of the girder and the club, the lifting and lowering of the gripping claws 9, and the grasping operation based on the applied signal.
2 is provided, and if necessary, the carry-in crane 7 is operated by a portable transmitter 33 independently of the carry-in crane control device 13.

In the figure, numeral 34 indicates a manual controller.

Note that the unloading crane control device 14 and the unloading crane 8 are the same as those on the injection side, and a description thereof will be omitted.

However, 35 is a coil destination display panel.

40 and 41 in Ig indicate a delivery vehicle and a delivery vehicle, respectively, and the delivery vehicle 40 is equipped with a radio 42,
The number of the coil Wa to be carried in is transmitted wirelessly to the carrying crane control device @13.

But that's fine.

Next, we will discuss the operating instructions.

The coil Wa carried in by a carrying vehicle (e.g. 4), +17 40 is first placed on the temporary storage stand 1, and at the same time the number of the coil Wa is transmitted to the Haruto crane control device 13 by the radio 42. do.

The coils Wa are classified by numbers in terms of the outer diameter, width, weight, etc. of the coils.

The carry-in lane control device 13 stores the required coil number manually from the host control device 12 in advance based on the production plan of the processing line M, and based on this, it is determined whether the coil Wa to be carried is necessary or not. This may be due to a mistake in keying the coil number as well as a transport error.
13 is determined to be a necessary coil, and by inputting the acceptance signal from the detector 5 of the temporary storage table 1, it is determined which receiving table it is, an activation signal is issued to the loading crane 7C, and the coil storage area 2 The storage location (address) is specified. As a result, the loading crane 7 is activated, and the coil W on the temporary storage stand 1 is
aG and transported to a designated predetermined position (address) in the coil storage area 2. in this case.

When the same type of coil is already placed in the coil storage area 2, the carry-in crane control device 13 memorizes this and issues a command to unload the coil to an adjacent position (address).

At the same time, this information is stored in the carry-in crane control device 13, and therefore, if necessary, the number of coils in operation on the fill storage area 2 can be displayed by type using the printer 20.

Next, when the upper control device 12 transmits the coil supply command to the machining line M and the coil number to the incoming crane control device f13, the incoming crane control device f13
A carp 7 with the corresponding number is detected, and an activation signal is issued to the incoming crane 7 along with the address of the coil storage area 2. As a result, the crane 7 grasps the fill Wa having a predetermined number. In this case, by providing the fill measurement sensor 28 on the carry-in crane 13 as described above, it is possible to prevent the supply from being overheard.

The loading crane 7 runs while gripping the coil Wa,
When reaching the upper part of the supply side of the processing line M, it is temporarily stopped. At the same time, the coil number is displayed on the coil number display board 18.

The operator actually compares the coil number attached to the coil Wa and thoroughly checks whether the force 1 matches or not. If there is a mismatch, by pressing the return button on the coil confirmation operation panel 19, the carry-in crane 7 is activated and the abnormal coil is automatically returned to a predetermined abnormal coil storage area (not shown).

When the winding direction of the coil is reverse winding, the coil gripping claw 9 is supplied onto the supply cart T of the processing line M after aligning the winding direction of the coil by 180 degrees with the predetermined direction.

When the coil Wa can be supplied as is to the supply cart T, the coil Wa is supplied as it is to the supply cart T by pressing the supply button.

Thereafter, the supply coil Wa is subjected to necessary processing in the processing line U by the host control device 12 and delivered to the delivery port 6.

Processed product coil being discharged from processing line M
The transportation method of b is almost the same as the above-mentioned input side! The material is supplied to the unloading truck 41 through the reverse process.

That is, when a payout request signal from the machining line is applied to the higher-level control device 12, the higher-level control device 12 transmits an operation signal together with the coil number to be paid out to the unloading crane control device 14. At this point, the control device 14 operates the unloading crane 8, picks up the product coil wb at the outlet of the processing line M, and transports it to a predetermined location in the product storage area B.

The product coil wb placed on the temporary storage stand 4 for dark storage is carried out M
When it is detected that the storage 41 has melted the liquid at Ifl' and the detector 6 has activated, the host controller 1
Based on a predetermined program, the higher-level control device 12 transmits the coil number to be carried out to the next cage and the carrying-out signal to the carrying-out crane control device. Based on this, the quality crane device 14 operates the unloading crane 8, grasps the designated address of the product coil storage area 6, that is, the required coil, and transports it to the temporary storage table 4. The simultaneous image destination display board 354 displays the destination number.

It goes without saying that the unloading crane control device 1i14 also stores the product coils wb remaining in the product coil storage area 3 for each type.

In addition, in the event that the host control device 12 malfunctions, both the loading crane 7 and the loading crane 8 will become inoperable, so the loading crane control device 13 and the loading crane 8 are used as backup devices. The control device 14 includes a device 1 that can input the coil number and coil number supply order, and a proxy control device 50, 51, such as a character display, etc.
This will allow the loading crane control device at13 to be installed.
, li) The crane control device 14 can be operated independently.

As described above, according to the present invention, each of the loading and unloading crane control devices includes a yard management control section that classifies and stores workpieces such as coils by type, and a crane operation control section. In addition, the crane can be operated by the crane control device to sort the workpieces by type and store them in storage areas, and to select and transport the workpieces, thereby making the operation work safer and improving the work efficiency. It has many advantages such as:
