BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll attaching / detaching apparatus for a roll grinder, which is easily automated for attaching / detaching a roll to be ground to / from a roll grinder for grinding a roll used in a rolling mill.

[0002]

2. Description of the Related Art Various rolls used for rolling are used repeatedly for re-use.
The roll surface must be ground each time after use for the purpose of removing metal oxides attached to the roll surface, metal fatigue layers on the roll surface, and the like.

A roll grinder is generally used for grinding the roll surface. The outline of roll grinding by this roll grinder will be described with reference to FIG. Roll grinding machine 1
Is provided with a fixed frame 3 on the driving side fixed on the base 2 for maintaining the grinding accuracy, and a sliding frame 4. Rotation centers 3 a and 4 a are attached to each other to face each other, and Configured for accuracy. In order to mount the roll 6 which is the object to be ground on such a roll grinder 1, first, the sliding frame 4 is separated from the fixed frame 3 by a length equal to or longer than the length of the roll 6, and is usually provided in advance horizontally. The roll 6 is supplied so that the center positions of the center holes on both end faces of the roll 6 are located on a line connecting the centers of the rotating centers 3a and 4a, and then the roll 6 is moved toward the fixed frame 3 to fix the fixed frame. The center hole of one end face of the roll 6 is externally fitted to the rotation center 3a of the roller 3, and then the sliding frame 4 is slid toward the fixed frame 3 so that the rotation center 4a of the sliding frame 4 is It fits into the center hole on the other end. At this time, the position at which the roll 6 is mounted on the roll grinder 1 is
As will be described later, this is also the position where the roll 6 that has been ground is removed, and is referred to as the roll attaching / detaching position of the roll grinder 1 in the following description.

However, such a roll grinder 1
, The fixed frame 3 is not stationary but is of a sliding type, and the roll 6 mounted between the fixed frame 3 and the sliding type frame 4 is moved (feeded) in the direction of the roll axis to grind it. On the other hand, the grinder 5 has a fixed position, or a grinding method of various combinations such as grinding while moving (feeding) in the axial direction thereof. May be substantially the same as at least the grinding position of the roll 6 actually ground by the grinder 5 at least on the roll axis, or may be completely different and have no direct relationship.

[0005] When the mounting of the roll 6 on the roll grinder 1 is completed in this way, the roll 6 at the roll attaching / detaching position, that is, the grinding position shown in FIG.
A jig (not shown) connected to a driving source provided on the fixed frame 3 is attached to one end of the roll 6 to rotate the roll 6 and to rotate the grinder 5 on the axis of the roll 6. While moving (feeding) in parallel with the direction of the core line and rotating and driving, it is pressed against the surface of the roll 6 for grinding. Conversely, on the other hand, when the roll 6 is ground while moving in the direction of its axis, the roll attaching / detaching position is not necessarily the same as the grinding position of the roll, and as an example,
The grinder 5 fixedly arranged is driven to rotate, and at the same time, the roll 6 on which the keray is attached is moved in parallel to the axial direction of the shaft (feeding) while rotating and pressing the grinder 5 rotating on the surface of the roll 6. One that can be applied and ground can be given. In any case, after the grinding is performed in this manner, the roll 6 attached to the roll attaching / detaching position may be removed and moved out of the roll grinder 1 by performing a procedure reverse to the above-described procedure. It is.

Conventionally, a roll grinding operation using a roll grinder as described above is performed based on the type of the roll to be ground (the presence or absence of a roll chock, the roll material, the shape and dimensions, and the like).
Roll weight, etc.), roll grinding method (roll grinder type, rotary grindstone type or endless belt type, roll supply / removal mechanism, roll rotation drive mechanism, roll feed drive mechanism, rotation of rotary grindstone, etc.) Each drive mechanism for pressing and feeding to the roll surface, whether or not grinding water or grinding oil is used and its supply mechanism, etc., and grinding conditions for rolls (each rotation speed, each feed amount and feed speed, pressing force, supply method and supply) Amount, dressing of grinding wheel surface, etc.), grinding control method and control mechanism (various sensors and their arrangements, various computers, etc.), etc., and vary depending on various requirements. Of course, one roll grinder And try to grind as many types of rolls as possible under a wide range of conditions.
Since this operation itself must be performed smoothly and efficiently with high precision, it has been extremely difficult to automate the operation. Therefore, such a roll grinding operation itself has been carried out exclusively by a manual operation using a roll grinder. However, supply of a roll to a roll attaching / detaching position on the roll grinder accompanying the roll grinding operation or this roll grinding operation has been performed. The work of attaching and detaching the roll for removing the mounted roll at the attachment / detachment position and moving the roll out of the roll grinder has necessarily been performed manually.

In other words, such a roll attaching / detaching operation is usually performed manually only for a light roll, while a heavy roll is operated by using a crane and a suitable roll suspender, or a light-weight operation for transportation. In other words, humans mainly operated and worked in some way, such as carrying and manipulating them using a free balancer or the like that enabled the operation.
In addition, the work of attaching and detaching the rolls has a considerable effect on the grinding work that must finish the target roll with high precision, so it must be performed carefully and accurately, and it is not a very good work Since the work is performed in the vicinity of a heavy object such as a roll in an environment, the burden on the operator is heavy, and the workability is poor in a poor environment, which involves a risk. Therefore, recently, not only the roll grinding work difficult to automate, but also the work of attaching and detaching the rolls to and from a series of roll grinders incidental to this grinding work is automated, not only to improve workability and safety. It is being promoted to reduce the burden on workers, and to save labor and improve productivity.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art and to constitute a roll attaching / detaching apparatus for a roll grinder which can be easily automated for attaching / detaching a roll to / from a roll grinder. I do.

[0009]

Means for Solving the Problems As a result of various studies, the present inventors have found that although the roll attaching / detaching position on the roll grinder is not necessarily the roll grinding position by the grinder,
Paying attention to the fact that there is at least a roll grinding position on the roll axis center line of the roll mounting / dismounting position or that a roll grinding position is provided, this face even faces the roll mounting / dismounting position on such a roll grinder. Provide a base that is immovable with respect to the roll attachment / detachment position. At least one of the front and rear and up and down directions (the direction toward the roll grinder is the front, and the opposite direction is the back) The two types of frames that can move in the vertical direction perpendicular to the vertical direction are respectively movable in the left and right directions by further adding the horizontal direction (the horizontal direction perpendicular to the front and rear direction is the left and right). In addition to assembling each of the three types of frames, when the roll is gripped or opened at a certain height, the height of the roll axis is always constant regardless of the roll diameter. By combining rolls grasping member configured to be constant, regardless of the various roll grinding manner by roll grinder was completed to the present invention investigated can achieve the above objects.

Hereinafter, a roll attaching / detaching apparatus for a roll grinder according to the present invention, which can be easily automated, will be described in detail with reference to the drawings. FIG. 1 is a front view showing an embodiment of a roll attaching / detaching apparatus for a roll grinder according to the present invention, which is easy to automate, and FIG.

The apparatus according to the present invention supplies the roll 6 to the roll attaching / detaching position of the roll grinder 1, or the roll grinder 1
Is a roll attaching / detaching apparatus for a roll grinding machine, which is easily automated for removing the roll 6 attached to the roll attaching / detaching position and moving the roll 6 to the outside of the roll grinder 1, and includes the following components. Then, as described above, when the roll 6 mounted on the roll grinder 1 is ground, the device of the present invention grinds the roll 6 without moving the roll 6 in the axial direction of the roll. Is the roll grinding position, and the configuration changes depending on the case where the roll attaching / detaching position in the grinding mode of grinding while moving the roll 6 in the axial direction thereof is not necessarily the roll grinding position. In the following description, first, the configuration of the device of the present invention having the minimum necessary parts to make it pass in any case will be described, and then the present invention having the parts necessary to pass in the former case will be described. The configuration of the device will be described.

Base (base or gantry): corresponding to the roll grinder 1 installed at a predetermined position,
The base of the whole roll attaching / detaching apparatus for the roll grinder which can be easily automated according to the present invention must be provided. A base provided as a base of the entire apparatus faces a substantially horizontal roll attaching / detaching position on the roll grinding machine 1 and has a fixed positional relationship to the roll attaching / detaching position. Such a base is related to other parts (other frames and members) to be described later, provided that it is configured so that the functions of the related other parts can be smoothly and sufficiently exerted. Good, specifically, various configurations are possible. As the base, a configuration of a lower frame 7 described later is preferable.

Upper frame 9: The upper frame 9 moves on a base that is immovable with respect to the roll attaching / detaching position in a horizontal direction perpendicular to the axis of the roll 6 at the roll attaching / detaching position. It is configured so that it can be stopped at a predetermined position so as to be movable by means 9e. Therefore, the upper frame 9 will be described in more detail by adding a lower frame 7 and a roll mounting table 8 which will be described later. The upper frame 9 preferably has a larger width than the roll mounting table 8 and 7, and is configured to be movable by the moving means 9 e on the lower frame 7 in a direction perpendicular to the roll axis center line direction of the roll attaching / detaching position and in a horizontal direction. In the illustrated example, the upper frame 9 is a side frame 9 on both sides which are vertically and parallelly erected at the same interval as the width of the lower frame 7.
a is fixed to both ends of the upper horizontal frame 9b and the lower horizontal frame 9c on the side of the roll grinding machine 1 and integrally formed, and sliders 9d attached to the lower surfaces of the side frames 9a on both sides are provided on both sides of the lower frame 7. It is slidably engaged with a slide bed 7e attached to the upper surface of the horizontal beam 7a. As shown in FIG. 2, as the moving means 9 e, for example, the end of the piston rod of the hydraulic double-acting cylinder is attached to the rear cross beam 7 b of the lower frame 7, and the cylinder outer cylinder is attached to the upper frame 9. Slide bed 7e mounted on horizontal beam 7a of lower frame 7
, That is, so as to be movable in the horizontal direction perpendicular to the axis of the roll 6 at the roll attaching / detaching position.

Elevating frame 11: The elevating frame 11 is a frame that is mounted on the roll frame 1 side of the upper frame 9 so that it can only move up and down. Roll gripping and releasing device mounting portion 11a for 12
Are provided in parallel with the axis of the roll 6 at the roll attaching / detaching position and at an interval substantially equal to or less than the length of the roll 6, and the both roll gripping and releasing device mounting portions 11a can be vertically moved by moving means 11f. It is configured to be able to stop at a predetermined position. This lifting frame 11 is
As described above, the shift frame 10 is not only attached to the upper frame 9 so that it can only move up and down, but also has a function different from that of the upper frame 9 as shown in FIGS. It can be mounted only up and down. Therefore, the lifting frame 11 will be described in more detail when the shift frame 10 is described later.

Roll gripping and releasing device 12: The roll gripping and releasing device 12 is attached to the lower part of each roll gripping and releasing device mounting portion 11 a of the elevating frame 11 at the same height, and the roll 6 at a predetermined position.
It is a device for gripping or releasing a device, and has the following configuration. In other words, the roll 6 is provided with two roll grippers 12a for gripping the roll 6 from both sides. As shown in FIG. 2, the roll gripper 12a has a concave portion 12aa opened in the vertical direction. 12aa is formed in a V-shape in which the opening end side is substantially evenly converged from the opening end to the deepest point 12ab, and the opening end side is wide. In the illustrated example, the concave portion 12aa of the roll gripper 12a converges linearly, but it is not always necessary and may be curved. Such a pair of roll grippers 12a are attached with their open ends facing each other in a direction perpendicular to the roll axis direction of the roll attaching / detaching position, and are moved by a moving unit 12e (for example, a rotary driving unit such as a hydraulic motor). The rolls 6 are gripped or released by moving toward or away from each other.

The overall configuration of the roll gripping and releasing device 12 in the illustrated example is as follows. As shown in FIGS. 1, 2 and 3, two roll grippers 12 a are arranged in such a manner that concave portions 12 aa each having an open end formed in a wide V shape are opposed to each other, and an upper portion opposite to the concave portion 12 aa. Base 12ac
Is attached to the roll holding and releasing device mounting portion 1 of the lifting frame 11.
The lower surface of the substrate 12b fixed to the lower part of the roll 1a is penetrated by two guide rods 12c fixed vertically and horizontally to the roll axis center line direction of the roll attaching / detaching position and slidably mounted. And both sides rotatably mounted between the two guide rods 12c are respectively screwed into screw portions on both sides of a screw rod 12d having opposite threads, and one end of the screw rod 12d is provided. Are connected to, for example, a hydraulic motor as a rotary drive source which constitutes the moving means 12e. In such a configuration, the interval between the roll grippers 12a of the roll gripping and releasing devices 12 on both sides is designed to be different from the interval between the two roll supporting portions 8a of the roll mounting table 8. In this configuration, a screw rod 12d is used as the moving means 12e by, for example, a hydraulic motor.
Is rotated in a certain direction, the two roll grippers 12a
Can approach each other and can be driven apart by rotating in opposite directions.

If the above-described base (base or gantry), upper frame 9, elevating frame 11, and roll holding / opening device 12 are provided at a minimum, the system can be used in any case as described above. Although it is possible to be a roll attaching / detaching device, it is very desirable to provide the necessary parts and pass each other in the former case where the roll attaching / detaching position of the roll grinder as described above is almost the roll grinding position. Go.

Lower frame 7: The lower frame 7 serving as a base of the entire apparatus is slightly touched in the description of the base (base or gantry) and each part of the upper frame 9. The positional relationship with respect to the position is fixed immovably. The configuration only needs to be such that the functions of the other frames and members are sufficiently exhibited, and various configurations are specifically possible.
In the illustrated example, the horizontal beam 7a on both sides, which is vertical and horizontal to the roll axis when the roll 6 is placed in the roll attaching / detaching position, and the center and rear cross beams 7b perpendicular to the horizontal beam 7a Between the four pillars 7c and the pillar 7c on the side of the roll grinder 1 in parallel with the roll attaching / detaching position and the cross beam 7b.
And a front cross beam 7d provided at a lower position at the same height.

Roll mounting table 8: The roll mounting table 8 is provided on a portion of the lower frame 7 on the side of the roll grinder 1, in the illustrated example, on a front cross beam 7 d, and substantially parallel to the roll attaching / detaching position. Roll support portions 8a for supporting both ends of the roll 6 at positions are provided at both ends thereof. The roll mounting table 8 is preferably provided at a lower position, that is, at least lower than the roll attaching / detaching position. The reason for this is to prevent the roll gripping and releasing device 12 and the elevating frame 11 and the shift frame 10 to which the roll 6 is mounted from hindering the movement of the roll 6 to the roll attaching / detaching position as described later. is there. The shape of the roll supporting portion 8a is substantially uniformly inclined from both sides toward the center as shown in the drawing.
Is stable at the lowest position, it is preferable that the distance between the roll axis on the horizontal projection plane and the roll axis at the roll attaching / detaching position is always substantially constant regardless of the roll diameter. If a necessary number of spare roll mounting tables 8 'are provided on the central cross beam 7b as shown in FIG. 3, for example, as a temporary roll storage place, the mounting place of the roll 6 removed from the roll grinder 1 can be determined. Since there is provided a place where the roll 6 is transferred from the roll storage site by an appropriate transfer device and is mounted on the roll grinder 1 and the transfer device is not restrained as much as possible, the operation rate can be increased. preferable.

Shift frame 10: The shift frame 10 is a frame necessary when the roll attaching / detaching position in the grinding mode for grinding without moving the roll 6 in the axial direction as described above is the roll grinding position, The upper frame 9 is fixed to a portion of the upper frame 9 on the side of the roll grinder 1, and is a predetermined position movably by a moving means 10e (for example, a hydraulic cylinder) in a direction parallel to the roll axis direction of the roll attaching / detaching position. It is configured to be able to stop. As shown in FIGS. 2 and 3, the shift frame 10 in the illustrated example has a horizontal upper horizontal frame 10a.
The lower portions of both vertical frames 10b are projected by a vertical frame 10b fixed vertically to the lower surface of the edge portion on the side of the roll grinder 1 and a lower horizontal frame 10c having both ends fixed to the vertical frame 10b. The upper horizontal frame 10a is placed on the upper horizontal frame 9b with the vertical frame 10b facing the roll grinder 1 and the upper horizontal frame 10b as shown in FIG. The slider 10d attached to the lower surface of the lower frame 10a and the lower portion of the side surface of the vertical frame 10b is fixed to the slide bed 9f attached to the upper and lower frames 9b and 9c of the lower frame 9c. It has a configuration of being detained. As shown in FIGS. 1 and 3, the end of the cylinder outer cylinder of the hydraulic cylinder and the tip of the cylinder rod as the moving means 10e are moved by the operation of the shift frame 10e.
The upper frame 9 along the upper horizontal frame 9b and the lower horizontal frame 9c, that is, in a direction parallel to the roll axis direction of the roll attaching / detaching position so as to be able to stop and move to a predetermined position, respectively. It is attached to the upper frame 9 and the shift frame 10.

Elevating frame 11 attached to shift frame 10: Elevating frame 11 is attached not only to upper frame 9 but also to shift frame 10 as described above, and roll grinding of shift frame 10 can be performed only in the vertical direction. Panel 1
A frame attached to a side portion of the frame, and two roll holding / opening device mounting portions 11a provided on both lower ends of the frame in parallel with a roll axis center line direction of the roll attaching / detaching position and a roll 6

1, the upper end of the rods 11b which are vertically arranged at intervals substantially equal to or less than the length of the roll 6 is connected to the connecting frame 1;
1c, the rods 11b are configured to be movable only in the vertical direction by a vertical guide 11d fixed to the side surface of the vertical frame 10b of the shift frame 10 on the roll grinding machine 1 side. In this case, the rod 11b
Is a roll gripping and releasing device mounting portion 11a. For example, a hydraulic cylinder is used as the moving means 11f, and the cylinder outer cylinder is connected to the vertical frame 10 of the shift frame 10.
b is fixed to the side surface of the lower horizontal frame 10c whose both ends are fixed to the connecting frame 1
1c is connected to the lower surface of the central portion.

Each moving means 9 used in each of the above parts
e, 10e, 11f, and 12e (specifically, for example, a hydraulic cylinder and a hydraulic motor as a rotary drive unit) stop operating when their respective frames and roll gripping members move to predetermined positions. By doing so, each can be stopped at that position. The present invention is configured as described above. Then, the roll 6 is driven to move to the roll attaching / detaching position of the roll grinder 1 and supplied, or is detached from the attaching / detaching position to perform attachment / detachment, as described in the next operation section. The automation of the roll attachment / detachment is performed by the upper frame 9, the shift frame 10,
Each movement of the elevating frame 11 and the roll gripper 12a of the roll gripper release device 12 is performed at an appropriate timing from a certain fixed position or from a certain pressed state to another fixed position described in the next section of operation. In addition, the proximity sensor 13 is installed at a necessary place, for example, at a position illustrated in each drawing, and further, although not shown and described, each control mechanism is provided, and each moving means 9e, 10e, The operation order of 11f and 12e can be easily realized by incorporating a program.

[0023]

The operation of the device according to the present invention will be described with reference to the example shown in FIG. In order to mount the roll 6, which is the object to be ground, on the roll grinder 1 by the device of the present invention, first, the moving means (hydraulic cylinder) 9e is operated to move the upper frame 9 laid on the lower frame 7 as a base. Is retracted to a position sufficiently distant from the roll mounting table 8 (hereinafter, this position is referred to as an upper frame first fixed position), and a predetermined roll 6 is moved from a roll storage such as a roll rack, for example. It is transported by a suitable transport device and is placed on the roll mounting table 8. At this time, when the roll attaching / detaching position of the roll grinder 1 is substantially the roll grinding position, the position of the center hole at the end of the roll 6 facing the fixed frame 3 side of the roll grinder 1 is set to the rotation center of the fixed frame 3. The position is slightly shifted to the sliding frame 4 side from the tip of 3a. Although the description of automating such mounting is omitted, it can also be performed by the transfer device side.

Next, the shift frame 10 is actuated by the moving means (hydraulic cylinder) 10e, and the roll gripping and releasing device 1 is moved.
The second roll gripper 12a is moved to a position where the roll 6 can be gripped as the position in the roll axis direction (this position may be a fixed position; hereinafter, referred to as a shift frame first fixed position). Thereafter, the upper frame 9 is moved to a sufficiently high position (hereinafter, referred to as the first fixed position of the elevating frame) by operating the moving means (hydraulic cylinder) 11f to move the upper frame 9 to the moving means (hydraulic cylinder). 9e is operated to advance the roll grinder 1 side, and the two roll gripping tools 1 of the roll gripping and releasing device 12 facing each other.
The center point of 2a is stopped at a position directly above a line connecting the lowest positions of the inclinations of the two roll supporting portions 8a of the roll mounting table 8 (this position is also a fixed position; hereinafter, referred to as an upper frame second fixed position). Let it. Since the roll supporting portion 8a of the roll mounting table 8 generally forms a concave portion having the lowest position as shown in the figure,
The roll axis of the placed roll 6 is substantially the lowest position on the horizontal projection surface regardless of the roll diameter, and thus the roll gripping and releasing device 12 faces when the upper frame 9 is at the upper frame second fixed position. It substantially coincides with a line connecting the center points of the roll grippers 12a. This match need not be exact.

Next, two opposing roll grippers 12a of each roll gripper releasing device 12 are in a position (hereinafter referred to as a roll gripper fixed position) sufficiently separated by the operation of the moving means (hydraulic motor) 12e. In this state, the elevating frame 11 is lowered by operating the moving means (hydraulic cylinder) 11f, and the deepest point 12a of the concave portion 12aa of the two opposing roll grippers 12a of the roll gripper opening device 12
b is stopped at a position (determined by the diameter of the roll; hereinafter, referred to as a second position of the lifting frame) at the same height as the roll axis of the roll 6 placed on the roll mounting table 8. The coincidence of the heights does not have to be exact.

Thereafter, the moving means (hydraulic motor) 12e is operated for each of the roll holding / opening devices 12 to bring the roll holding tools 12a closer to each other so as to be mounted on the roll mounting table 8 between the concave portions 12aa. The roll 6 is held.
At this time, since the upper and lower shapes of the concave portions 12aa are formed in a V-shape with a wide open end, the position of the roll axis is accurately positioned in the middle between the concave portions 12aa of the two roll grippers 12a facing each other. Can be held between the concave portions 12aa even if the rolls 6 do not coincide with each other.
In the middle between 2a, the height is the deepest point 1 of each recess 12aa.
Exactly matches 2ab. In other words, the position of the axis of the roll 6 held by the roll gripping and releasing device 12 is a fixed position on the roll gripping and releasing device 12 parallel to the roll axis at the roll attaching / detaching position regardless of the roll diameter. This will be referred to as the roll gripper axis center position). The parallelism between the two is not necessarily required to be accurate.

Next, the lifting frame 11 is raised by operating the moving means (hydraulic cylinder) 11f, and the axis position of the roll gripper is the same height as the position of the roll axis line at the roll attaching / detaching position (this is the third position of the lifting frame 3). Stop at the position where it has been called (fixed position). Then, the moving means (hydraulic cylinder) 9e is operated to move the upper frame 9 forward on the lower frame 7 toward the roll grinder 1, so that the axis position of the roll gripper is higher than the position of the roll axis at the roll attaching / detaching position. And stop at a position where the front and rear positions coincide (this coincident and overlapping position is referred to as an upper frame third position) (before this forward operation, the sliding frame 4 of the roll grinding machine 1 is sufficiently moved from the fixed frame 3). Of course).

In this state, the moving means (hydraulic cylinder) 10
e, the shift frame 10 of the present invention is moved to the fixed frame 3 side of the roll grinding machine 1, and the center hole of the end face of the roll 6 is fitted to the rotation center 3a (at this time, the shift frame 10 The position is referred to as a shift frame second fixed position). Next, the sliding frame 4 is slid toward the fixed frame 3, and the rotation center 4 a is fitted into the center hole of the end face of the roll 6. The operation of the sliding frame 4 can be automated on the roll grinding machine 1 side.

The operation of the apparatus of the present invention described above is an operation required when the roll attaching / detaching position of the roll grinder 1 is almost the roll grinding position. In some cases, the frame 3 does not move but slides in the same manner as the sliding frame 4, and the roll 6 mounted between the frames 3 and 4 is moved while moving in the direction of the roll axis. In this case, in the above-described operation of the present invention, the shift frame 10 itself and the operation of the shift frame 10 are unnecessary, and the operation of the shift frame 10 is performed by sliding the shift frame 10 in the roll axis direction. What is necessary is just to perform on the roll grinding machine 1 side which has 3 and 4. The operation of the fixed frame 3 and the sliding frame 4 that substantially slide can be automated on the roll grinding machine 1 side.

Since the mounting of the roll 6 on the roll grinder 1 has been completed, the roll 6 is released by separating the roll gripper 12a of the roll gripper releasing device 12 to the roll gripper fixed position. The roll 6 is still mounted on the roll grinder 1), and the upper frame 9 is returned to the first upper frame fixed position with the elevating frame 11 raised to the first fixed position of the elevating frame. In addition, the operation order of each frame or member does not necessarily have to be the procedure described above,
For example, the lifting frame 11 may first be raised to the lifting frame first fixed position, then the upper frame 9 may be advanced to the upper frame second fixed position, and then the shift frame 10 may be moved to the shift frame first fixed position.

In order to remove the roll 6 mounted on the roll grinder 1 and finished grinding, and to move the roll 6 to the outside of the roll grinder 1, basically, the operation in the reverse procedure described above may be performed. For example, first, the lifting frame 11 is moved to the first lifting frame.
The upper frame 9 is moved up to the home position, and then the upper frame 9 is advanced to the upper frame third home position.
To the shift frame second fixed position, then move each roll gripping tool 12a of the roll gripping and releasing device 12 to the roll gripping tool fixed position, and then lower the lifting frame to the lifting frame third fixed position, Then two opposing
After the two roll grippers 12a are brought close to each other to hold the roll 6 between the grippers 12e, the sliding frame 4 of the roll grinder 1 is slid and separated from the roll 6 so that the rotation center 4a is located at the end face of the roll 6. Release from the center hole, move the shift frame 10 to the shift frame first fixed position, then raise the lifting frame 11 to the lifting frame first fixed position, and then move the upper frame 9
Is retracted to the second fixed position of the upper frame, then the elevating frame 11 is lowered to the second fixed position of the elevating frame, and the roll 6 is mounted on the roll mounting table 8. The roll 6 is opened by separating the roll 12 from the roll holding member 12a to the fixed position, and then the upper frame is retracted to the first fixed position of the upper frame with the lifting frame 11 raised to the first fixed position of the lifting frame.

As a result, since the roll 6 has been moved from the roll grinder 1 to the roll mounting table 8 of the device of the present invention, the roll 6 is thereafter transported to a roll storage place by an appropriate transport device. If the preliminary roll mounting table 8 ′ is provided, while the roll 6 is being ground by the roll grinder 1, the transport device transports the next predetermined roll 6 to the roll mounting table 8. After mounting, the device of the present invention transfers the roll 6 placed on the roll mounting table 8 to the preliminary roll mounting table 8 ′ so that the roll 6 after grinding can be moved to the roll mounting table 8 at any time. If the roll 6 that has been ground cannot be immediately conveyed by the conveying device, the next roll 6 mounted on the preliminary roll mounting table 8 ′ is mounted on the roll grinder 1. Or the roll 6 that has been ground is suddenly moved from the roll grinder 1 to the preliminary roll mounting table 8 ′, and the next roll 6 that has been transported in advance and is mounted on the mounting table 8 continues to be used. To be attached to Both mounting tables 8,
The grounded roll 6 can be selectively moved to an empty mounting table in 8 '. In this manner, the grinding operation rate of the roll grinder 1 can be improved as much as possible, and the transport device for transporting the rolls 6 and the like can be prevented from being excessively restrained from being carried into and out of the roll grinder 1. Other conveyance can be performed in large quantities with margin. In other words, in the case where the auxiliary roll mounting table 8 'is provided, in any case, it is only necessary to operate each of the frames and members described above in accordance with the work described above. What is necessary is just to automate in response to.

In order to stop the movement of each part composed of each frame and member at each fixed position, each moving means 9e, 10e, 11f, 12e (for example, a hydraulic cylinder or a hydraulic motor as a rotary driving means) Proximity sensor 13 is installed at each required fixed position, including the use of the moving end (stroke end) of, and for confirming whether or not it is stopped reliably, and each control mechanism is disposed. If the start of the movement is operated by a switch, the work of attaching and detaching the roll 6 can be automated by avoiding the vicinity of the roll grinder 1 and the device of the present invention.

As described above in detail, the easily attachable / detachable apparatus for a grinding machine according to the present invention faces a roll attaching / detaching position on a roll grinding machine, and has a fixed positional relationship with respect to the roll attaching / detaching position. A base as a base is provided, and a lower frame as such a base is provided with two types of frames that are movable in each of the front and rear directions and up and down directions, and a frame that is movable in the left and right directions. Movable 3
In addition to combining different types of frames, in the state where the roll is gripped or opened at a certain height corresponding to the mounting / detaching position of the roll, the height of the axis of the roll regardless of the roll diameter is large. By properly operating a roll gripper configured so as to be always constant, the roll is reliably positioned at the roll attaching / detaching position on the roll grinder, that is, the roll grinder of the center hole of the roll both end faces. The centering with the rotating center can be performed accurately and the necessary parts and the operation of each part can be set and minimized in accordance with the roll grinding mode of the roll grinder.

Therefore, it is easy to automate the entire apparatus, and this automation eliminates the work of attaching and detaching the rolls to and from the roll grinder, which has been mainly operated and operated by humans in some form, and reduces the heavy burden on the operator. In addition to eliminating the danger associated with this work, a series of roll grinding processes can be automated by combining robots with transport devices such as rolls and combining them with an automated NC roll grinder. Therefore, not only safety but also high productivity can be secured at the same time, and the industrial value of the device of the present invention is very large.
