In the above-described conventional article storage rack, when the interval between the upper end portions of the pair of frame structures changes due to an earthquake, the damping mechanism is deformed in the horizontal direction, whereby the deformation vibration of the frame structure is attenuated. When the interval between the upper end portions of the pair of frame structures does not change, the damping mechanism does not function, and the vibration of the frame structure cannot be effectively attenuated.

For example, as in the article storage rack in the automatic storage device having the storage crane, each of the frame members is configured to have the same height and the same length in the width direction of the frame. In this case, the vibration characteristics of each of the pair of frame structures are The same characteristics. In addition, the vibration characteristics of the pair of frame structures may be the same due to the storage state of the objects housed in the frame structure.

When the vibration characteristics are the same, when an earthquake occurs, the upper end portions of the pair of frame structures vibrate in a state in which the phases are aligned, and therefore, there is a There is no change in the interval between the upper end portions of the opposing frame structures.

As described above, when the interval between the upper end portions of the shelf structure does not change, the attenuation mechanism that attenuates the deformation vibration in the horizontal direction does not function as the above-described attenuation mechanism. Therefore, it is difficult to make the frame structure. Vibration attenuation.

In view of the above, an object of the present invention is to provide an article storage rack capable of appropriately attenuating deformation vibration of a frame structure.

In order to achieve the object, a first feature of the article storage rack according to the present invention is characterized in that a pair of frame structures are provided in a state in which they are arranged side by side in the front-rear direction of the frame, and the frame structure is configured to be disposed on the frame. A pair of front and rear pillars on the front side and the back side of the rack are provided with a damping mechanism for attenuating the deformation vibration of the rack structure.

In the article storage rack, each of the front side pillars of the pair of frame structures and the back side pillars of the racks are pivotally connected to the front and rear width directions of the beam members arranged along the front and rear width directions of the rack. In the different positions, the attenuating mechanism is disposed at a position different from the beam member and the frame structure at a position different from the beam member and the pivotal connection position of the column in the front-rear direction.

According to the present feature, each of the front side pillars and each of the back side pillars of each of the pair of frame structures are pivotally connected to the beam members disposed along the front and rear width directions of the frame, and the damping mechanism is For example, in a position different from the beam member and the pivotal connection position of the pillar, the upper portion and the beam member are joined, and the lower portion and the frame member are connected, and the frame is set to span the beam member and the frame. Composition. Therefore, the frame structure is shaken by the earthquake, When the pair of pillars before and after the frame structure are deformed and vibrated, the beam member is pivotally connected to the horizontal axis by the position at which the pillars of the respective frame members are pivotally connected to each other, and vibrates. Thereby, the force in the compression direction and the force in the pulling direction act on a pair of attenuation mechanisms in the direction of the shelf in a position different from the position at which the beam member and the column pivotally connect. The damping mechanism is deformed by the traction force and the compressive force, whereby the deformation vibration of the frame structure can be attenuated.

As described above, according to the present configuration, the deformation vibration in the horizontal direction of the upper end portion of the pair of frame structures is converted into the deformation vibration in the vertical direction of the beam member, whereby the upper end portions of the pair of frame structures are The rocking phase of the deformation vibration in the horizontal direction is uniform, and the vibration deformation of the frame structure can be attenuated, and the deformation vibration of the frame structure can be appropriately attenuated.

According to a second aspect of the article storage rack of the present invention, the pillar on the front side of the rack of each of the pair of rack structures is pivotally connected to the beam member, and the damping mechanism is in the front and rear direction of the rack. In the paired state, the frame is set to each of the both end portions of the beam member and the back side pillars of the pair of frame members.

According to this characteristic configuration, when the pair of frame structures are deformed and vibrated by the shaking of the earthquake, the pivotal connection position of the upper end portion of each of the pair of frame structures is a fulcrum, and the force in the up and down direction acts on the beam. The location where the member and the attenuation mechanism are connected. In other words, the force in the compression direction acts on the damping mechanism of the upper end portion of the pillar on the back side of the one frame structure, and the force in the pulling direction acts on the upper end portion of the pillar on the back side of the shelf structure in the other frame structure. Attenuating mechanism, or vibration is carried out while traction and compression are The opposite combination acts on the attenuation mechanism. In this way, the deformation vibration in the horizontal direction of the upper end portion of the pair of frame structures is converted into the deformation vibration in the vertical direction of the beam member, whereby the deformation vibration of the horizontal direction of the upper end portions of the pair of frame structures is shaken. When the phases are the same, the vibration deformation of the frame structure can be attenuated, and the deformation vibration of the frame structure can be appropriately attenuated.

According to a third aspect of the present invention, the article storage rack is configured such that a plurality of pairs of the paired frame structures are provided in a state in which the back side of the rack is adjacent to each other, and the beam member is configured to span the plurality of pairs in the front-rear direction. a continuous form of the body, wherein the pillars on the back side of the shelf in the plurality of pairs of frames are pivotally connected to the beam member, and the attenuation mechanism frame is disposed across each of the plurality of frame members The pillar on the front side and the beam member.

When the attenuating mechanism is placed on the rack back side pillar of the beam member and the rack structure, for example, a configuration in which the back sides of the adjacent rack structures are coupled to each other or a pair of rack members is placed on the back side of the rack. In the configuration in which the pillars are shared by the common pillars, when the plurality of frame structures connected by the two members are deformed and vibrated by the earthquake in the upper portion, the beam members are simultaneously generated: a pair of the pair of frame members The pivotal connection position is a change in the posture of the fulcrum, and a posture change of the pivotal connection position of the pair of frame members adjacent to the fulcrum is a position at which the back side of the frame body is adjacent to the frame member in the front-rear direction of the frame member. The force acting on both sides: the force in the pulling direction caused by the change of the posture of the beam member which is connected to the one side of each of the pillars on the back side of the joined frame and the beam member The force in the compression direction (or the force in the traction direction) caused by the change in the posture of the beam member constituting the body side portion of the other pair of frames, makes the beam member difficult Since it is displaced up and down, there is a possibility that the deformation vibration of the frame structure cannot be appropriately attenuated.

In this regard, the present configuration is such that the connection between the pair of front and rear pillars in the beam member and the frame structure is changed to the above-described configuration, whereby the pillars on the back side of the rack are used as fulcrums, and are placed in the front-rear direction of the rack. At the position where the pillar on the front side is located, the force acting in the direction in which the beam member is changed in position causes the pillars and the attenuating mechanism of the beam member which are mounted on the front side of the rack to be deformed, and the deformation of the frame body can be deformed. The vibration is reduced.

As described above, according to the present configuration, when the pair of frame structures are deformed and vibrated by the shaking of the earthquake, the frame and the beam member are attenuated by the abutment on the front side of the frame, and the frame structure can be appropriately deformed. Vibration attenuation.

The beam member is coupled to the beam member, and the attenuating mechanism is formed in a paired state in the front-rear direction of the frame, and the frame is provided at each end portion of the beam member and the back side of each frame connecting the pair of frame members The horizontal pillars of the pillars and the pillars on the front side of the frame.

According to this characteristic configuration, when the pair of frame structures are deformed and vibrated by the shaking of the earthquake, the pivotal connection position of the upper end portion of each of the pair of frame structures is a fulcrum, and the force in the up and down direction acts on the beam. Both ends of the member. In other words, the force in the compression direction acts on the attenuation mechanism that is connected to the intermediate portion of the frame structure in the front-rear direction of the frame structure, and the force in the traction direction acts on the attenuation mechanism that is coupled to the other frame structure. In this way, the horizontal deformation vibration of the upper end portion of the pair of frame structures is converted into a beam structure. By the deformation vibration of the material in the vertical direction, even when the rocking phases of the deformation vibrations in the horizontal direction of the upper end portions of the pair of frame structures are matched, the vibration deformation of the frame structure can be attenuated, and the frame can be appropriately formed. The deformation vibration of the body is attenuated.

Since the damper mechanism is connected to the intermediate portion in the front-rear direction of the frame structure, even if the frame constituting body has a plurality of article accommodating portions arranged in parallel in the front-rear direction of the frame, the frame is calculated from the fulcrum of the front side pillar. The distance in the direction is shorter than the distance to the back side pillar, whereby the excessive weight applied to the pivotal connection position of the front side pillar and the beam member and the force applied to the damping mechanism can be excessively suppressed.

According to a fifth aspect of the article storage rack of the present invention, the upper end portions of the pair of front and rear pillars have the same height, and the damping mechanism is disposed in a state in which the beam member is in a posture along the horizontal direction.

Most of the frame structures in the conventional article storage rack are configured such that the heights of the pillars are the same height. According to this characteristic configuration, in the conventional frame structure, the damping mechanism is placed in a state in which the beam member is in the horizontal direction. Therefore, the present invention can be suitably applied to the conventional frame structure.

According to a sixth aspect of the article storage rack of the present invention, the beam member and the damping mechanism are coupled to each other in a state in which the upper side portion of the damping mechanism is received in the upper and lower webs of the beam member.

According to this characteristic configuration, since the beam member can be disposed in the vertical direction with respect to the upper end portion of the frame structure, the increase in the height of the article storage rack caused by the installation of the beam member can be made as small as possible, and Enough to achieve intensive up and down direction.

According to a seventh aspect of the article storage rack of the present invention, the beam member is a beam of a building provided with the pair of frame structures.

According to this characteristic configuration, since the upper end portions of the pair of frame structures can be connected by the beam of the building in which the pair of frame structures are provided, the configuration can be simplified by using the components, and The beam connects the pair of frame structures and the building, and the strength of the frame structure can be improved.

According to an eighth aspect of the article storage rack of the present invention, a plurality of the beam members are disposed at intervals in the direction of the shelf.

According to this characteristic configuration, since a plurality of the beam members are arranged at intervals in the direction of the shelf, the upper portions of the pair of frame structures are coupled to a plurality of positions in the direction of the shelf. Therefore, the strength of the article storage rack is improved, and the deformation vibration of the frame structure can be effectively attenuated by the damping mechanism connected to the plurality of beam members.
