DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of accurately managing, for example, a storage place where a large number of members are centrally stored, without the need to manually confirm the storage situation.
The present invention relates to a member yard management facility capable of quickly moving members.

[0002]

2. Description of the Related Art Conventionally, a housing (hereinafter referred to as a roll housing) in which rolling rolls used in a rolling mill, such as a stretch reducer, a sizer, etc., for rolling a seamless steel pipe or the like are concentrated in one place. Then, a roll housing (hereinafter, referred to as a necessary roll housing) in which necessary rolling rolls are stored is selected from the storage space.

[0003] If a roll housing is selected incorrectly and supplied to a mill line, a rolling trouble may be caused and the machine may be stopped for a long time. Conventionally, the place of the roll housing has been managed as follows.

[0004] The roll housing is colored with a different paint for each type of roll, or a mark is imprinted on the roll housing. In this method, the required roll housing is selected by specifying the required roll housing from the entire storage space based on the color and the stamp of the paint. Also,
When returning the roll housing to the storage area, the roll housing is placed in an empty area of the storage area.

[0005] The place where the roll housing is placed is attached with a number tag of the place. In this method, in order to select the required roll housing, from a list in which the numbers of the yards where the roll housings are arranged are recorded one by one, the number of the premises where the required roll housings are currently located is specified and performed. I have. When the roll housing is to be returned to the storage space, the roll housing is placed in a vacant space of the storage space, and the number of the place where the roll housing is placed is recorded in the above list.

The housing H can be replaced according to the arrangement, and the storage situation changed by the arrangement can be accurately recorded.

In this case, it is determined whether the storage space is empty or the housing H matching the storage space is placed. If the storage space is empty, the housing H matching the storage space is detected. And put it in the yard.
On the other hand, when the housing H that does not match the place is placed, the housing H is temporarily moved from the place, the housing H that matches the place is detected, and the housing H is placed in the place. Rearrangement is performed by repeating such processing.

Of course, the preferred mode of using the management equipment 1 is not only the management of the storage space of the housing H storing the rolls and the like as described above, but also the management of the storage space of various members. In addition, in order to contribute to factory automation in recent years, it is also possible to incorporate and use it in an automation line, and to perform receipt / shipment management and inventory management based on recording information of the recording device 4C.

As described above, the management facility 1 of the present invention identifies a specific housing H among a plurality of housings H,
The necessary movement amount of the housing H and the required holding / mounting operation are detected, and these states are recorded one by one by the recording device 4C, so that the movement state of the housing H can be recorded. In addition, the storage status can always be updated accurately with the latest information, so that the confirmation work by humans, which was performed to improve the reliability of the storage management, becomes unnecessary, and the storage is managed with high efficiency and high accuracy. can do.

The management equipment 1 of the present invention is not limited to the above embodiment, but can be variously modified. For example, the method of reading the identification number of the housing H
May be provided with a bar code of an identification number, and this may be optically read by the moving device 3 side. However, in the case of this method, in a place where there is a lot of dust, the barcode becomes dirty,
If dirt adheres to the scanner as the optical reading device, it may not be possible to read accurately, so it is necessary to consider a place and a place situation.

In the management facility 1 of the present invention, the travel distance detector 31A and the traverse distance detector 32A detect the position in the travel range from the travel cable 31b and the traverse cable 32b in the above embodiment. I tried to do
For example, you may make it detect the rotation amount of the motor for driving | running | moving and traverse drive.

Similarly, the holding / placement detecting unit 34A detects a load when the housing H is held or placed in the holding / placement mechanism 34, for example, in addition to the detection method described in the above embodiment. Alternatively, the state of holding and placing may be detected. Further, in the management facility 1 of the present invention, the communication between the mobile device 3 and the management device 4 is performed wirelessly in the above embodiment, but may be performed by wire.
