Hereinafter, the configuration of the roll stand and the position data delivery device will be described in detail with reference to FIGS. 1 and 2.
Each roll stand 1 is provided with an upper roll, a lower roll, and left and right side rolls [working side roll (WS), drive side roll (DS)] and for adjusting the position of each roll. Drive device for adjustment (not shown, but a motor or the like is used), and the position of each roll, that is, the height position of the upper roll and the lower roll, the left and right positions of the work side roll and the drive side roll A position detector (an example of a position detector, specifically, a pulse generator or the like is used) 11 and a zero point position detector of an upper and lower roll (an example of a position detector, A load cell that detects the mutual pressing force to know the contact state is used. For the lower roll, the height from the floor surface is detected as an absolute position, and for the upper roll, the center-to-center height with respect to the lower roll is obtained as a relative distance. Is required. In the zero point adjustment, the distance between the centers of the two rolls is obtained based on the position of the upper and lower rolls at that time based on the signal from the zero point position detector 12. This calculation is performed by, for example, a calculation unit provided in the zero point position detector 12. However, this zero point adjustment is performed only in the assembly line K.
[0013]
Further, each roll stand 1 (1a, 1b) is provided with a stand discriminator (an example of stand discriminating means) 13 (13a, 13b) for identifying the roll stand itself. In the present embodiment, it is only necessary to distinguish between the A roll stand 1a arranged on the production line L and the B roll stand 1b arranged on the assembly line K. Therefore, the stand identifier 12 has three terminals 14 (14a). , 14b, 14c) and a jumper wire 15 for connecting two of the three terminals.
[0014]
For example, when recognizing the B roll stand 1b arranged in the assembly line K, the second and third terminals 14b and 14c are connected to each other by the jumper wire 15, and the A roll arranged in the production line L is used. In order to recognize the stand 1a, the first and third terminals 14a and 14c may be connected by the jumper wire 15.

Since the stand discriminator 13 itself has a jumper wire structure, it may be provided in the connector portion 17.
[0016]
Further, in this rolling facility, the adjustment position data (relative position data for the upper roll and absolute position data for the lower roll) of each roll adjusted in the assembly line K is stored for each roll stand 1. When the roll stand 1 is moved to the production line L, a data delivery device 21 is provided for delivering the adjustment position data to the production side.
[0017]
This data delivery device 21 includes an assembly-side connector portion (assembly-side connection portion) 22 that can be connected to and separated from, for example, a connector portion 17b on the B-roll stand 1b side that is arranged on the assembly line K, and an A that is arranged on the production line L The manufacturing side connector part (manufacturing side connection part) 23 that can be connected to and separated from the connector part 17a on the roll stand 1a side, and the adjustment position data of each roll inputted via the assembly side connector part 22 are input line switching. The circuit 24 includes a first adjustment data storage unit 25 and a second adjustment data storage unit 26 which are separately input and stored in accordance with the A roll stand 1a and the B roll stand 1b, respectively, and the manufacturing side connector unit 23. And a rolling data storage unit 27 for storing the rolling position data at the time of rolling of each roll input via the roll, and the assembly line K. In response to an identification signal from the stand discriminator 13 of the roll stand 1, the input line switching circuit 24 is operated to input the data input destination to the first adjustment data storage unit 25 or the second adjustment data storage unit 26. A switching signal for switching is generated, and based on the identification signal by the stand discriminator 13 from the roll stand 1 moved to the production line L, the adjustment position data of the roll stand 1 is stored in the first adjustment data storage unit. 25 or a data control unit (data control circuit) 28 for transferring from the second adjustment data storage unit 26 to the rolling data storage unit 27.
[0018]
For the connector parts 17a and 17b, the assembly side connector part 22 and the manufacturing side connector part 23, auto couplers that can be automatically connected and disconnected are used from the viewpoint of speed of operation. For example, the assembly side connector part 22 and the manufacturing-side connector 23 can be moved relative to each roll stand 1 by the cylinder devices 29 and 30. Of course, a simple one that can be connected and disconnected manually can be used.
[0019]
Next, the mold changing operation will be described.
First, in the assembly line K, the connector part 17b of the B-roll stand 1b is connected to the assembly-side connector part 22, and at the same time, the B-roll stand 1b is sent to the data controller 28 by the identification signal of the stand discriminator 13b.

[0020]
And after incorporating the new roll which should be changed in B roll stand 1b, the drive device for adjustment is driven and each roll is moved to an appropriate position.
Specifically, first, the position (height) of the lower roll from the floor surface is determined, and then the upper roll is brought into contact with the lower roll, and zero adjustment is performed so that the gap between the two rolls becomes zero.
[0021]
Next, after determining the position (height) of the upper roll by raising the upper roll by a predetermined dimension from the position at the time of the zero point adjustment, the positions of the left and right side rolls are determined.
Therefore, the position data of each roll, that is, the position data at the time of adjustment is stored in the second adjustment time data storage unit 26, respectively.
[0022]
When the adjustment work of the roll in the assembly line K is completed, the connector part 17b of the B roll stand 1b is separated from the assembly side connector part 22, and the production line L is stopped to connect the connector part 17a of the A roll stand 1a to the production side. After separating from the connector part 23, the A roll stand 1a is moved to an empty place on the assembly line K.
[0023]
Next, the B roll stand 1 b of the assembly line K is moved to the production line L side (indicated by an arrow a), and the connector portion 17 b is connected to the production side connector portion 23.
[0024]
Then, based on the signal from the stand discriminator 13b, the data control unit 28 recognizes that the stand moved to the production line L is the B roll stand 1b, and from the second adjustment time data storage unit 26, The position data at the time of adjustment of the stand is transferred to the rolling data storage unit 27 to be an initial value of each roll, and used for subsequent rolling control.
[0025]
In this way, the position data at the time of adjustment obtained on the assembly line K side can be used as it is on the production line L side, and therefore a roll stand incorporating a new roll is moved to the production line as before. When this is done, there is no need to adjust the position of each roll, that is, zero point adjustment in this production line, so the production line is not stopped for a long time.
[0026]
By the way, in the said embodiment, although the delivery of the position data at the time of adjustment of a roll in the case of moving the B roll stand where the adjustment of the roll was completed in the assembly side line to the production side line, Also, when the A roll stand that has been rolled is moved to the assembly side line (indicated by the arrow b), on the contrary, the rolling position data stored in the rolling data storage unit 27 is also Based on the identification signal from the stand discriminator 13a, it is transferred to the first adjustment data storage unit 25 according to an instruction from the data control unit 28, and the subsequent roll adjustment operation can be performed easily and quickly. ing. Therefore, the data control unit 28 incorporates an instruction for bidirectionally transferring data between the rolling data storage unit 27 and the adjustment data storage units 25 and 26.
[0027]
Moreover, in the said embodiment, although the case where two roll stands were replaced | exchanged was demonstrated, for example, three roll stands can also be used. In this case, three adjustment position data storage units provided in the data delivery device are provided, and an input line switching circuit capable of switching three units is used.
[0028]
【The invention's effect】
As described above, according to the data delivery device of the present invention, the position data at the time of adjustment obtained on the assembly line side can be used as it is on the production line side. Therefore, the manufacturing line is not stopped for a long time. That is, the roll stand can be replaced quickly.
