Definitions
- This invention relates to a vibration control rack for an automatic warehouse.
- Patent Document 1 JP2003-118819A
- JP2003-118819A a viscoelastic body
- each rack is basically the same structure and the natural period is almost equal, and even if the racks are connected by a damper, a sufficient vibration control effect cannot be obtained. Therefore, the inventor studied a vibration suppression structure that does not depend on the difference in natural period.
- An object of the present invention is to dampen a rack without depending on the difference in natural period.
- This invention is an automatic warehouse rack provided along the traveling space of the loading and unloading device,
- the rack has a structure including a front column closer to the traveling space, a rear column disposed away from the traveling space, a diagonal brace disposed between the front column and the rear column, and a tensile brace and a damper crossing each other.
- a front column closer to the traveling space a rear column disposed away from the traveling space
- a diagonal brace disposed between the front column and the rear column
- a tensile brace and a damper crossing each other.
- two types of structural units are provided by reversing the arrangement of the tensile brace and the damper.
- the front strut close to the traveling space, the rear strut at a position away from the traveling space, and the front strut and the rear strut are arranged obliquely and cross each other.
- the tensile bracelet is a brace that has different stiffness between tension and compression so that it does not deform with respect to tension but deforms with respect to compression.
- the normal breath is designed not to be deformed by both compression and tension.
- the damper is a viscoelastic damper that uses energy absorption by the viscoelastic body, an oil damper, or the like.
- the rack can withstand force in any direction along the short side of the rack and can absorb energy. . For these reasons, it is possible to reduce the shaking at the top of the structural unit, and to prevent the storage article from dropping and the automatic warehouse from being damaged.
- the description relating to the rack also applies to the rack damping method as it is, and the description relating to the rack damping method also applies to the rack itself.
- racks are provided on both sides of the traveling space and connected to each other, and two types of structural units are arranged symmetrically between the racks on both sides of the traveling space. If it does in this way, it can control with sufficient balance on both sides of a running space.
- two types of structural units are alternately arranged along the traveling space. In this way, vibration can be controlled in a well-balanced manner along the longitudinal direction of the traveling space.
- the two types of structural units have no bottom layer of the rack, and the rack is a truss structure on the top.
- the structural unit that combines the tension brace and the damper is a modified truss structure, so it can be connected naturally to the top of the truss structure, and can be controlled at the bottom of the rack to limit the top swing. .
- Front view of the automated warehouse of the example 1 is a perspective view of the automatic warehouse of FIG.
- the perspective view of the rack of a modification The figure which shows the deformation
- FIGS. 1 to 6 show an embodiment and its modifications.
- reference numeral 2 denotes an automatic warehouse, and a pair of racks 4 and 5 are provided on both the left and right sides of a traveling space 3 of a loading / unloading apparatus such as a stacker crane.
- the front strut 6 is provided near the traveling space 3
- the rear strut 7 is provided on the opposite side (the heel side when viewed from the traveling space 3)
- 8 is a beam.
- Reference numeral 12 denotes a normal brace, and a truss structure is formed by the support columns 6 and 7 and the brace 12 and the beam 8.
- Reference numeral 10 denotes a connecting portion of the racks 4 and 5, and the automatic warehouse 2 of the embodiment is a unit type automatic warehouse.
- Reference numeral 16 denotes a viscoelastic damper, which may be an oil damper.
- the structure of the damper 16 is shown in FIG. 40 is an inner steel plate, 42 is a viscoelastic plate such as rubber or synthetic resin, 44 is an outer steel plate, and when the viscoelastic body plate 42 is sandwiched between the steel plates 40 and 44 and the steel plates 40 and 44 are relatively displaced, the viscoelastic plate 42 expands and contracts to absorb kinetic energy.
- the damper 16 can absorb kinetic energy for both compression and extension. *
- the tension brace 14 and the damper 16 are crossed with each other so that the columns 6 and 7 are connected.
- the tensile brace 14 and the damper 16 are connected at the lower end to the base side and at the upper end to the columns 6 and 7, but the upper end may be connected to the beam 8 instead of the columns 6 and 7.
- Two types of combinations of the tension brace 14 and the damper 16 are provided by reversing the arrangement, one of which is an ⁇ portion 18 and the other is a ⁇ portion 19. As shown in FIGS. 1 and 2, the ⁇ part 18 and the ⁇ part 19 are arranged symmetrically on the left and right of the traveling space 3, and the ⁇ part 18 and ⁇ are arranged along the longitudinal direction of the traveling space 3 as shown in FIG. 2.
- the parts 19 are arranged alternately. However, only the ⁇ portion 18 may be provided in the rack 4 and only the ⁇ portion 19 may be provided in the rack 5. Moreover, it is not restricted to what arrange
- alpha part 18 and beta part 19 are arrange
- positioning Racks may be arranged on the left and right of the traveling space 3. In this case, combinations of ( ⁇ portion 18, ⁇ portion 18) and ( ⁇ portion 19, ⁇ portion 19) appear alternately on the left and right of the traveling space 3.
- the deformation of the racks 4 and 5 is limited and the vibration can be efficiently controlled regardless of the force applied from either side of the automatic warehouse 2 in the short side direction (left and right direction in FIG. 1).
- the rack is more rigid than the lowermost layer in the second layer or higher, so the vibration is absorbed in the lowermost layer, and the upper layer Can limit shaking.
- the support columns 6 and 7 can be shared by the lowermost layer and the upper layer.
- FIG. 3 shows a modified automatic warehouse, in which only the rack 4 is provided on one side of the traveling space 3.
- the racks 4 and 5 do not support each other, the ⁇ portions 18 and the ⁇ portions 19 are alternately arranged along the longitudinal direction of the traveling space 3. That is, the ⁇ portion 18 supports the rightward force in FIG. 3 and the ⁇ portion 19 supports the leftward force.
- FIG. 7 shows a comparative example in which the dampers 16 are arranged so as to cross each other and the tensile brace 14 is not provided.
- the energy from the earthquake can be absorbed by the damper 16, but the rack is greatly deformed and the shaking becomes intense.
- the deformation of the racks 4 and 5 can be limited by the tensile brace 14.
- the racks 4 and 5 can be damped without using the difference in natural period, and can be damped with only one rack. 2)
- the tensile brace 14 can absorb kinetic energy while limiting the swing of the racks 4 and 5.
- the deformation of the racks 4 and 5 can be limited even if a force is applied from any of the short sides of the racks 4 and 5.
- the ⁇ part 18 and ⁇ part 19 are provided in the lowermost layer, and the racks 4 and 5 are truss structures above the lowermost layer, the upper layer has high rigidity and the lowermost layer has low rigidity, so vibration is absorbed in the lowermost layer. This makes it difficult to reach the upper layer.
- the support columns 6 and 7 can be shared by the lowermost layer and the upper layer.
- the ⁇ portion 18 and the ⁇ portion 19 are provided in the lowermost layer, but the ⁇ portion 18 and the ⁇ portion 19 may be provided in the middle layer or the like. Further, it is not necessary to configure the lowermost layer of the rack entirely with the ⁇ part 18 and the ⁇ part 19. For example, a normal brace 12 may be provided in a part of the lowermost layer.
