Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll shop for servicing rolls, chocks, etc., which are the basis of rolling work.

[0002]

2. Description of the Related Art Conventionally, as a roll conveying method of a roll shop, for example, JP-A-5-111705, JP-A-5-111706, and JP-A-5-111707.
A roll shop described in Japanese Patent Publication is known. In these publications, in order to avoid roll or chock transport by crane transport that requires positioning time, rolls, chock, etc. are loaded on a trolley provided with wheels and moved along a guide rail. I am trying to carry it.

Then, for example, in the mill yard, a roll or chock is run along the guide rails and is transported to the loading / unloading port of the mill yard. Then, in the roll shop, a transverse carriage that can move in a direction perpendicular to the guide rail is arranged in advance, and a pull-in guide rail is laid parallel to the guide rail with the transverse carriage interposed therebetween. A maintenance device such as a roll grinder or a roll storage rack is arranged beside the side of the. Then, the rolls, chocks, etc. transported to the loading / unloading port of the mill yard are loaded on the traverse carriage together with the carriage, and the traverse carriage is moved in the direction perpendicular to the guide guide rail to face the pull-in guide rail corresponding to the desired maintenance device. The rolls, chocks, etc. are transported to the desired position.

Then, when it moves to a predetermined position,
Rolls, chocks, etc. on the traverse trolley are transferred onto the guide rails, moved to a predetermined position where they can be loaded on the maintenance device, moved along the guide rails, and then placed on the specified maintenance device. It is supposed to do.

[0005]

However, in the above-mentioned conventional roll shop, for example, when the rolls on the roll grinder have been subjected to the maintenance process and the rolls have been replaced, the rolls on the roll grinder can be replaced. Is placed on the pull-in guide rail, the roll after the regeneration treatment on this pull-in guide rail is placed on the traverse trolley, and, for example, it is conveyed to a position facing the pull-in guide rail corresponding to the roll storage rack, After transferring the roll on the traverse trolley to the pull-in guide rail of the roll storage rack, move the traverse trolley to a position facing the pull-in guide rail on which another roll to be regenerated next is placed, Place this roll on the traverse trolley and position it again facing the pull-in guide rail corresponding to the roll grinder. In moving the transverse trolley, in the same manner as described above, draw on the pull guide rails corresponding roles to roll grinder, so as to install the roll on the roll grinder.

Therefore, in order to replace the rolls to be regenerated by the roll grinder, the traverse carriage must reciprocate between the roll grinder and the roll storage rack, and it takes time for the traverse carriage to move. There is a problem that it takes time to switch rolls in the grinder. Further, since it takes time to replace the rolls, the roll grinder becomes empty during that time, and there is an unsolved problem that the operation efficiency of the roll grinder is poor.

Therefore, the present invention has been made in view of the above-mentioned unsolved problems of the prior art, and an object thereof is to provide a roll shop capable of improving the operating efficiency of a roll grinder.

[0008]

In order to achieve the above object, a roll shop according to a first aspect of the present invention is a roll shop that conveys a maintenance member to a predetermined placement area, and maintenance that is conveyed to the placement area. In a roll shop including a placement device for placing a member on a maintenance device, the roll shop is adjacent to the placement region, outside the movement region of the maintenance member between the transfer means and the maintenance device, and the maintenance device. It is characterized in that it has a standby area in which a member can temporarily stand by. Therefore, if the maintenance member is made to stand by in the standby area in advance, when the maintenance member is replaced with the maintenance device, the maintenance member placed in the placement area is transported from the maintenance device by the transport means, and the placement area is emptied. At this point, the maintenance member in the standby area is moved to the placement area, is placed on the maintenance device, and the maintenance process is started.

The roll shop according to claim 2 is
The standby area is provided on the back side of the placement area. Therefore, since the standby area is on the back side of the placement area, that is, on the extension of the maintenance member in the conveyance direction to the placement area of the conveyance means, the maintenance member is linearly transferred to the standby area. Further, the roll shop according to claim 3 is
It is characterized in that it has a sub-standby region capable of temporarily holding the maintenance member between the placement region and the movement region of the transport means. Therefore, if the maintenance member placed on the placement area from the maintenance device is transferred to the sub-standby area and is conveyed from the sub-standby area by the conveying means, the maintenance member in the standby area is irrespective of the conveyance state of the maintenance member by the conveying means. It is transferred to the mounting area, which is mounted on the maintenance device.

Next, the structure of the mounting device 21 will be described with reference to FIG. FIG. 3 shows details of the XX cross section of FIG. The placement device 21 includes a traveling frame 20 disposed in parallel with the traverse guide rail 7 on top of the roll grinders 10a and 10b including the pull-in guide rail 8b, and an upper carriage 45 traveling along the traveling frame 20. It consists of and.

A motor 46a and a bevel speed reducer 46b are arranged on the upper carriage 45, and the driving force of the motor 46a is transmitted to the drive wheels 46c so that the upper frame 45 travels on the traveling frame 20. Lifting arms 48a and 48b that are vertically movable with respect to the traveling frame 20 are fixed to the upper carriage 45, and are driven by a lifting arm driving device 49 provided in the upper carriage 45. ing.

The elevating arm driving device 49 is composed of, for example, a motor 50, a bevel speed reducer 51, a pinion 52, and a rack 53 fixed to the elevating arm 48. It is transmitted to the rack 53 via the bevel speed reducer 51 and the pinion 52, whereby the elevating arms 48a and 48b are formed to move in the vertical direction. A horizontal arm 55, which is horizontally driven by an electric cylinder 54, is disposed below each of the elevating arms 48a and 48b. Then, with the upper carriage 45 positioned on the retractable guide rail 8b, the elevating arms 48a, 48a.
8b is lowered, the horizontal arm 55 is driven in the horizontal direction, and the engagement pin 56 fixed to the tip of the horizontal arm 55 is engaged with the flange portion 11a formed on the upper roll chock 11 or the lower roll chock 12. The upper roll chock 11 or the lower roll chock 1 is lifted by raising the elevating arms 48a and 48b while engaging the lower surface.
It is designed to lift 2.

Two sets of the mounting devices 21 are arranged in parallel, and each mounting device 21 simultaneously supports the respective chocks 11a, 11b or 12a, 12b of the roll set 13, whereby the upper roll chock 11 is formed. Alternatively, the lower roll chock 12 is lifted and moved. Next, the operation of the above embodiment will be described with reference to FIG.

Now, for example, it is assumed that the roll grinder 10 is performing the reproduction process on the roll set 13M (state 1). In this state, for example, the roll set 13N stored in the roll storage rack 9 is next regenerated. First, the traverse carriage 14 is moved to a position facing the pull-in guide rail 8a in which the roll set 13N of the roll storage rack 9 is stored. Then, when the transverse carriage 14 comes to a predetermined position, it drives the transfer device 15 of the transverse carriage 14 to connect the transfer device 15 to the connection hole 12c of the roll set 13N stored on the pull-in guide rail 8a. The pin 41 is engaged and the roll set 13N is transferred onto the transverse carriage 14. Then, in this state, the transverse carriage 14
Is moved to move the transverse carriage 14 to a position facing the pulling guide rail 8b for the roll grinder.

Then, the transfer device 15 is driven again to place the roll set 13N on the traverse carriage 14 on the pull-in guide rail 8b. This allows roll set 1
3N is moved to the entry side position A on the pull-in guide rail 8b (state 2). From this state, the retracting device 17 is driven as shown in FIG. Then, the retracting carriage 32 is moved to the bearing unit 37a side, the electric cylinder 42 on the bearing unit 37a side is driven to project the connecting pin 41, and the connecting pin 41 is engaged with the connecting hole 12c on the side opposite to the entry side. In this state, the motor 34 is rotated in the reverse direction to move the pull-in carriage 32 in the direction C toward the non-entrance side and stop it at a predetermined position.

As a result, since the connecting pin 41a is engaged with the connecting hole 12c of the roll set 13N,
Along with the movement of the pulling carriage 32, the roll set 13N
Moves toward the counter-entrance side position C using the pull-in guide rail 8b as a guide, and stops at the counter-entrance side position C (state 3). In this state, when the regeneration processing for the roll set 13M by the roll grinder 10 is completed, the upper carriage 45 is driven to move the lower roll chock 1 as shown in FIG.
The upper carriage 45 is moved to the upper part of the roll grinder 10b on which 2 is placed. Next, the lifting arm drive device 49
To lower the elevating arms 48a and 48b,
When the lower portions of the arms 48a and 48b reach the lower surface of the lower roll chock 12, the electric cylinder 54
Is driven to project the horizontal arms 55 in the horizontal direction opposite to each other, and the engagement pin 56 fixed to the tip of the horizontal arm 55 supports a position on the lower surface of the lower roll chock 12 that does not hit the wheels. The elevating arms 48a and 48b are again raised to raise the lower roll chock 12. Then, in this state, the upper carriage 45 is driven to move the lower roll chock 12 to the upper part of the pull-in guide rail 8b, and the elevating arms 48a and 48b are lowered again to be placed on the pull-in guide rail 8b. Similarly, the upper roll chock 11 is pulled in from the roll grinder 10a, and the lower roll chock 12 on the guide rail 8b.
Place on top. As a result, as shown in state 4 of FIG. 4, the roll grinder 10 is in an empty state, and the roll set 13M after the regeneration processing is located at the mounting position B on the pull-in guide rail 8b. At this time, the roll set 13N before the regeneration process is located at the counter-entrance side position C.

Next, the retraction device 17 is driven to move the retraction carriage 32 to an intermediate position between the mounting position B and the counter-entry side position C, and in this state, the coupling device 31 is driven to the bearing unit 37a side. Roll set 1 connecting pin 41 of
The connection pin 42 on the side of the bearing unit 37b is engaged with the connection hole 12c on the side opposite to the 3M side, and the connection pin 42 on the side of the bearing unit 37b.
The connection hole 12c on the N entry side position side is engaged. Then, in this state, the pull-in carriage 32 is mounted on the bearing unit 3
Move in 7b direction. As a result, the retractable carriage 3
As the roll set 13 moves, the roll sets 13M and 13N move together on the pull-in guide rail 8b and the transverse guide rail 7
The roll set 13M that has been regenerated is moved to the entry side value A, and the roll set 13N that has not been regenerated is moved to the mounting position B (state 5).

Therefore, the loading device 21 is driven, and the lifting arms 48a and 48b are driven and the upper carriage 45 is moved repeatedly in the same manner as described above to set the upper roll chock 11 of the roll set 13N on the loading position B. The lower roll chock 12 is placed at a predetermined position of the roll grinder 10a, and the lower roll chock 12 is placed at a predetermined position of the roll grinder 10b. As a result, the processing by the roll grinder 10 is started (state 6).

Then, for example, while driving the placing device 21, the transverse carriage 14 is driven to move the transverse carriage 14 to a position facing the pull-in guide rail 8b for the roll grinder, and when the carriage reaches a predetermined position. The transfer device 15 of the carriage 14 is driven to transfer the regenerated roll set 13N at the entrance position A onto the traverse carriage 14 (state 7). Then, the traverse carriage 14 is driven, and the traverse carriage 14 is moved to, for example, a position facing a predetermined guide guide rail 27 on the mill yard 2 side or a position facing a predetermined pull-in guide rail 8a of the roll storage rack 9. Let Then, when it comes to a predetermined position, the transverse carriage 1
The roll set 13N on 4 is transferred onto the guide guide rail 27 or the pull-in guide rail 8a. As a result, the reproduction process for the roll set 13M ends.

Then, for example, when there is a roll set 13 that needs to be newly regenerated, the roll set 13 is placed on the traverse carriage 14 and the traverse carriage 14 is driven in the same manner as above. And pull in guide rail 8b
To the position opposite to the pull-in guide rail 8b
The roll set 13 is transferred on top. Then, the retraction device 17 is driven to move the roll set 13 to the reverse entrance side position C.
It is moved to, and is made to stand by at this position, and thereafter the same processing is performed.

Therefore, according to the above-described embodiment, the roll sets of the roll grinder 10 can be exchanged on the pull-in guide rail 8b. Therefore, the time required for the exchange of the roll sets is the roll set 13 being regenerated. From the time when the paper is transferred to the mounting position B on the pull-in guide rail 8b, the roll set 13 before the regenerating process, which is waiting at the counter-entry side position C, is moved to the mounting position B, and the roll set 13 is moved to the predetermined position of the roll grinder 10. It is only until it is placed in the position, and the time required to replace the roll set can be greatly shortened.

Further, since the roll set replacement time can be shortened, the operating rate of the roll grinder 10 can be improved, and the number of roll grinders 10 can be reduced. Therefore, the cost can be reduced, and the space of the roll shop can be reduced by the amount of the reduced roll grinder. Further, since the operation rate of the roll grinder is improved, it is possible to reduce the number of spare roll sets to be held, and thus it is possible to reduce the cost.

Incidentally, when comparing the conventional roll set replacement method in which the traverse carriage 14 reciprocates between the roll grinder 10 and, for example, the roll storage rack, the conventional roll set replacement method is compared. In the method, the replacement time is 7 minutes and the operation rate of the roll grinder 10 is 89%, whereas in the roll set replacement method according to the present invention, the replacement time is 2 minutes and the operation rate is 96%. It can be seen that the operating rate can be greatly improved while being shortened to.

In the above embodiment, the case where the roll set before and after the regeneration process is made to stand by at the entrance side position A and the counter entrance side position C with the placing position B sandwiched is explained. However, for example, only when the anti-entry side position C is provided and the roll set before the regenerating process is on standby, and at the same time when the roll set after the regenerating process is moved by the transfer device 15 of the traverse carriage 14, Even when the retracting device 17 is used to move the roll set at the non-entrance side position C to the mounting position B, it is possible to reduce the time required to replace the roll set in the roll grinder 10 as in the above. . However, since the roll set is made to stand by at the entry side position A and the counter entry side position C with the placement position B interposed therebetween, it is irrelevant to the placement state of the roll set after the regeneration processing on the transverse carriage 14. In addition, the roll set can be replaced according to only the processing state of the roll grinder.

In the above embodiment, the case where one roll set 13 is set to stand by at the entrance side position A and the counter entrance side position C on the pull-in guide rail 8b has been described. A plurality of roll sets 13 are provided at the side position A and the counter-entry side position C, respectively.
It is also possible to make the roll grinder 10 stand by, even if the traverse carriage 14 cannot immediately convey the roll set 13 to be next subjected to the regeneration processing, the roll grinder 10 will not be in an empty state and will be more effective. The roll grinder can be operated.

Further, in the above embodiment, two sets of connecting devices 31 are arranged in the retracting device 17 before and after the retracting carriage 32 in the traveling direction, and in the state of state 4 in FIG.
The case where the roll sets at the mounting position B and the counter-entry side position C are moved at the same time has been described. For example, after the roll set at the mounting position B is moved to the entrance side position A, the rolls at the counter-entry side position C are moved. Although it is possible to move the set to the mounting position B, it is possible to replace the roll sets in the roll grinder by simultaneously moving the roll sets at the mounting position B and the counter-entry side position C. The time required can be further shortened.

Further, in the above embodiment, the case where the roll chock is conveyed to the roll grinder has been described, but the present invention is not limited to this, and is the same as in the case where the roll chock is conveyed to another maintenance device such as a chock remover. The effect of can be obtained. Further, in the above embodiment, the case where the entrance side position A, the placement position B, and the counter entrance side position C are provided on a straight line and the roll set 13 is linearly moved has been described, but the present invention is not limited to this. It is sufficient that the roll set 13 located at the counter-entry side position C can be moved to the mounting position B when the position B becomes empty. For example, the traverse guide rail 7 of the roll grinder can be used. The adjacent position on the opposite side to is set as the counter entrance side position C so that the roll set 13 is made to stand by here, and the roll set 13 is pulled in and the guide rail 8
It is also possible to move in an oblique direction with respect to b. Further, for example, when the roll grinder is provided only on one side of the pull-in guide rail 8b, it is possible to set the counter-entry side position C on the opposite side of the roll grinder with the pull-in guide rail 8b sandwiched therebetween. . However, if the roll set 13 is provided on a straight line as in the present embodiment, the moving distance of the roll set 13 is the shortest, and the pull-in guide rail 8b may be the shortest length, which can be realized at low cost and requires a small space. Is the best.

As described above, according to the roll shop of the first aspect, the standby area adjacent to the placing area is formed in the area other than the moving area of the maintenance member between the conveying means and the maintenance device. Therefore, when the processing is completed, the maintenance member transferred from the maintenance device is conveyed from the placement area by the conveying means, and when the placement area is empty, the maintenance member in the standby area is transferred to the placement area and the maintenance device is moved. Can be installed in
Therefore, the maintenance members can be replaced in a short time, and the operating rate of the maintenance device can be improved.

Further, according to the roll shop of the second aspect, since there is the standby area on the inner side of the placement area, that is, on the extension of the maintenance member in the carrying direction to the placement area of the carrying means, the maintenance member is provided. Can be transferred to the standby area by linear movement, the maintenance member can be transferred to the standby area with a shorter transfer distance, and the maintenance member can be replaced in a shorter time.

Further, according to the roll shop of the third aspect, the maintenance member after the maintenance by the maintenance device is made to stand by in the sub-standby area formed between the placing area and the moving area of the conveying means. For example, since the placement area becomes an empty area and the next maintenance member can be transferred to the maintenance device, the maintenance member can be replaced regardless of the transportation state of the transportation means, and the transportation means waits for transportation. Since the time can be reduced, the operating rate of the maintenance device can be further improved.
