Description

The present invention relates to an installation device and an installation method for a vibration damping device.

As an automated warehouse that contributes to the efficiency of distribution systems, we know that an automated warehouse is configured by arranging multiple racks side by side in parallel and installing stacker cranes on rails laid on the floor between the racks so that they can run. Has been done. The stacker crane is equipped with a loading platform that moves up and down along the main pillar and a fork that loads and unloads the load on the pallet. The rack is provided with an opening on the front surface on the crane side so that the load can be loaded and unloaded by the stacker crane. A cargo cradle overhanging from a support column is provided at this opening so that a pallet loaded with a load to be stored can be placed on the cargo cradle.

Many of such automated warehouses have a large tower ratio in order to secure a large amount of storage in a small area, and there is a risk that stored items may fall from the top of the rack during an earthquake. As a method of reducing the response of the rack during an earthquake and preventing the stored items from falling, a movable mass adjusted according to the natural frequency of the rack structure and a damper for damping the vibration of the movable mass are provided. There is a vibration control measure that installs a vibration control device at the top of the warehouse.

Japanese Patent No. 5925591

Since the installation structure of Patent Document 1 requires a drive mechanism for deploying the fixing member, there is a problem that the structure becomes complicated and the weight of the vibration damping device is increased. Further, with the fixing member described in Patent Document 1, it seems difficult to transmit the vibration damping force acting on the vibration damping device having a weight of several hundred kg to the pillar.

From such a viewpoint, it is an object of the present invention to provide an installation device and an installation method of a vibration damping device capable of reliably installing a vibration damping device in an automated warehouse with an easy and lightweight configuration.

The first invention for solving such a problem is an installation device for a vibration damping device for fixing a vibration damping device having a movable mass to a pallet accommodating portion whose four corners are surrounded by pillars. A base frame spanned between cargo receiving stands provided on both sides in the width direction of the pallet accommodating portion, a moving frame provided so as to be movable in the width direction of the pallet accommodating portion with respect to the base frame, and the moving frame.

According to the installation device of such a vibration damping device, if the first moving means and the second moving means are moved by separate driving devices, it is not necessary to provide the driving device in the vibration damping device. Therefore, the configuration of the vibration damping device is not complicated and weight reduction can be prevented. Further, the moving frame can be surely brought into contact with the pillar along the width direction, and the contact member can be brought into contact with the pillar along the depth direction. Further, since the moving frame and the abutting member abut on the pillar along the direction in which they intersect with each other, the fixing strength of the vibration damping device to the pillar can be increased.

In the installation device of the vibration damping device according to the present invention, it is preferable that the first moving means is a pantograph jack and the second moving means is a feed screw mechanism. According to such a configuration, the moving frame and the contact member can be moved with a simple configuration.

A second invention for solving the above-mentioned problems is a method for installing a vibration damping device for fixing a vibration damping device having a movable mass to a pallet housing portion whose four corners are surrounded by pillars, and the pallet housing.

The driving device includes a moving frame moving step of moving the moving frame to bring it into contact with the pillar, and a contact member moving step of moving the contact member with the driving device to bring it into contact with the pillar. It is characterized by that.

According to such an installation method of the vibration damping device, since the vibration damping device, the installation device and the drive device are conveyed by the stacker crane, it is not necessary to install and disassemble the temporary scaffolding. Further, since the moving frame and the contact member are moved by a drive device separate from the installation device, the moving frame can be reliably brought into contact with the pillar along the width direction, and the contact member can be brought into contact with the pillar. It can be brought into contact with the pillar along the depth direction. Further, since the moving frame and the abutting member abut on the pillar along the direction in which they intersect with each other, the fixing strength of the vibration damping device to the pillar can be increased.

According to the installation device and the installation method of the vibration damping device of the present invention, the vibration damping device can be reliably installed in the automated warehouse with an easy and lightweight configuration.

The installation method of the vibration damping device 1 according to the present embodiment includes a preparation process, a vibration damping device transporting process, a driving device moving process, a moving frame moving step, and a contact member moving step.

The preparatory step is a step of fixing the installation device 8 to the vibration damping device 1. Further, in the preparatory step, the pantograph jack of the first moving means 30 is in a folded state, and the moving frame 20 is kept close to the connecting member 13. Further, each contact member 40 is moved toward the center in the depth direction so as not to come into contact with each support column 2.

As shown in FIG. 6, the vibration damping device transporting process is a step of transporting the vibration damping device 1 provided with the installation device 8 to the pallet accommodating portion S at the installation position of the vibration damping device 1 by using the stacker crane C. .. In the vibration damping device transfer process, the base frame 10 provided at the lower part of the vibration damping device 1 is bridged over the receiving bars 4 and 4 of the load receiving stands 5 and 5 provided on the front, rear, left and right columns 2, respectively.

As shown in FIG. 7, the drive device moving step is a step of moving the drive device 60 for driving the first moving means 30 and the second moving means 50 to a position facing the vibration damping device 1 by the stacker crane C. be. The drive device 60 controls to drive the first drive shaft 61 for driving the first moving means, the second drive shaft 62 for driving the second moving means, and the first drive shaft 61 and the second drive shaft 62. It is equipped with a device 63.

The first drive shaft 61 is provided at two locations facing each first moving means 30. The first drive shaft 61 is formed so as to be expandable and contractible with respect to the first moving means 30. The first drive shaft 61 expands and contracts between the accommodation position in the casing of the drive device 60 and the connection position connected to the first moving means 30. A connecting portion 64 to the first moving means 30 is formed at the tip of the first drive shaft 61. The connecting portion 64 rotates by engaging with the receiving member 36a that fits into the hole of the hexagon socket head cap screw 36 provided at one end of the screw rod 35 of the first moving means 30.

As shown in FIG. 9, the connecting portion 64 is formed in a weight shape in which the tip is narrowed, and a plurality of grooves along the axial direction are formed radially on the surface thereof. The groove of the connecting portion 64 and the claw portion of the receiving member 36a mesh with each other, and the connecting portion 64 and the receiving member 36a are locked to the rear of the rotation. The connecting portion 64 is formed thinner than the concave receiving portion of the receiving member 36a, and maintains the locked state even when the axial direction of the first drive shaft 61 and the axial direction of the hexagon socket head cap screw 36 are inclined. It is configured so that the rotational force can be transmitted.

The first drive shaft 61 tilts so that the tip portion moves outward in the left-right direction while rotating. Specifically, the first drive shaft 61 is attached to the motor 67, and the rear end portion of the motor 67 is pin-coupled to a slide base 68 that can move in the front-rear direction. The motor 67 and the first drive shaft 61 are configured so that the tip portion of the first drive shaft 61 is swung left and right.

The second drive shaft 62 is provided at a total of four locations, two on the left and one on the right, facing each second moving means 50. The second drive shaft 62 is formed so as to be expandable and contractible with respect to the second moving means 50. The second drive shaft 62 expands and contracts between the accommodation position in the casing of the drive device 60 and the connection position connected to the second moving means 50. A connecting portion 65 to the second moving means 50 is formed at the tip of the second drive shaft 62. The connecting portion 65 is fitted into a hole of a hexagon socket head cap screw 54 provided at one end of a screw member 51 of the second moving means 50 and rotates. The second drive shaft 62 is configured so that the connecting portion 65 rotates without moving left and right.

In the drive device moving step, the drive device 60 is placed on the stacker crane C and moved in front of the vibration damping device 1 installed in the pallet accommodating portion S. In this state, the first drive shaft 61 and the second drive shaft 62 are degenerate into the casing of the drive device 60 (a state in which the shafts 61 and 62 are degenerate into the drive device 60 is not shown).

As shown in FIGS. 8 and 9, the moving frame moving step is a step of moving the moving frame 20 outward in the width direction to bring it into contact with the support column 2. In the moving frame moving step, the motor 67 and the first drive shaft 61 are moved rearward from the state of FIG. 9A, and the first drive shaft 61 is inserted into the opening 15 of the guide member 11. Then, the connecting portion 64 at the tip of the first drive shaft 61 is engaged with the receiving member 36a fitted to the hexagon socket head cap screw 36 provided at one end of the screw rod 35 of the first moving means 30 (FIG. 9). (B)). At this time, the first drive shaft 61 extends along the front-rear direction. After that, the first drive shaft 61 is rotated. As a result, the pantograph shaft expands and the moving frame 20 expands outward in the width direction. At the same time, since the screw rod 35 also moves outward in the width direction, the connecting portion 64 also moves outward. Along with this, the motor 67 and the first drive shaft 61 are tilted about the pin 69, and the first drive shaft 61 is tilted in the front-rear direction (see (c) in FIG. 9). At this time, the motor 67 and the first drive shaft 61 move slightly rearward to keep the connecting portion 64 and the receiving member 36a in a locked state. Here, since the opening 15 has a predetermined length in the width direction, even if the first drive shaft 61 is tilted, it does not interfere with the peripheral edge of the opening 15. The moving frame 20 is moved to a position where the outer surface abuts on the inner side surface of the support column 2. Then, the rotational torque is measured by the tightening device, and when the predetermined torque is reached, the rotation of the first drive shaft 61 is stopped. As a result, each moving frame 20 presses the support column 2 with a predetermined pressure.

The contact member moving step is a step of moving the contact member 40 in the front-rear direction to bring it into contact with the support column 2. In the abutting member moving step, each second drive shaft 62 is extended, and the connecting portion 65 at the tip of each second drive shaft 62 is inserted into the hole of the hexagon socket head bolt 54 provided at the front end portion of the screw member 51. Fit each one. After that, each second drive shaft 62 is rotated. As a result, each contact member 40 moves toward the adjacent column 2. The front contact member 40 is moved to a position where the contact surface abuts on the rear side surface of the front support column 2. The rear contact member 40 is moved to a position where the contact surface abuts on the front side surface of the rear column (see FIG. 3). Then, the rotational torque is measured by the tightening device, and when the predetermined torque is reached, the rotation of the second drive shaft 62 is stopped. As a result, each contact member 40 presses the column 2 with a predetermined pressure.

In the vibration damping device 1 installed by the above installation method, the moving frame 20 presses the support column 2 outward along the width direction from the inside of the pallet accommodating portion S, and the contact member 40 presses the support member 2 outward along the depth direction. Since the support column 2 is pressed outward, the moving frame 20 can be brought into contact with the support column 2 from the inside to the outside along the width direction, and the contact member 40 can be brought into contact with the support column 2 from the inside to the outside along the depth direction. It can be brought into contact with the support column 2 so as to face it. That is, since the columns 2 at the four corners can be pressed in four directions along the directions in which the moving frame 20 and the abutting member 40 intersect each other, the vibration damping device 1 can be firmly fixed to the columns 2. Therefore, the vibration damping force acting on the vibration damping device 1 can be reliably transmitted to the support column 2.

In particular, in the present embodiment, the moving frame 20 is moved via the pantograph jack, and the contact member 40 is moved via the feed screw mechanism, so that the moving frame 20 has a relatively simple structure and is in contact with the moving frame 20. It can move with the member 40. By controlling the rotational torques of the first drive shaft 61 and the second drive shaft 62, the vibration damping device 1 can be more firmly fixed to the support column 2.

Further, in the present embodiment, since the first moving means 30 and the second moving means 50 are driven by using the driving device 60 provided separately from the installation device 8, the vibration damping device 1 is used to drive the first moving means 30 and the second moving means 50. There is no need to provide means. Therefore, it is possible to prevent the configuration of the vibration damping device 1 from becoming complicated, and it is possible to prevent the vibration damping device 1 from becoming heavier.

Further, according to the installation method of the vibration damping device 1 according to the present embodiment, since the vibration damping device 1 and the drive device 60 are transported to a predetermined position by the stacker crane C, it is not necessary to install and disassemble the temporary scaffolding. Is. Therefore, the labor and time for installation work can be reduced.

Although the embodiment for carrying out the present invention has been described above, the present invention is not limited to the above-described embodiment and can be appropriately modified without departing from the spirit of the present invention.
