Description

この発明は、柱部材と梁部材を有する複数の架構を備えた収容棚の制震構造に関する。   The present invention relates to a vibration control structure for a storage shelf including a plurality of frames having column members and beam members.

収容棚の制震構造に関する従来技術としては、例えば、特許文献１に開示された制振ラックと制振方法が知られている。
特許文献１に開示された制振ラックでは、制振ラックの長辺方向において間隔を空けて２本の柱が設置されており、この２本の柱が短辺方向に一対設けられている。
長辺方向における両側の柱に腕木がそれぞれ取り付けられており、腕木には棚受け本体がそれぞれ設けられている。
棚受け本体と腕木との間には制振部材として粘弾性体が介在されている。 For example, a damping rack and a damping method disclosed in Patent Document 1 are known as conventional techniques related to the damping structure of the storage shelf.
In the vibration control rack disclosed in Patent Document 1, two pillars are provided at intervals in the long side direction of the vibration suppression rack, and a pair of these two pillars is provided in the short side direction.
Arms are respectively attached to the pillars on both sides in the long side direction, and the shelf support main body is provided on each arm.
A viscoelastic body is interposed as a damping member between the shelf support body and the arm.

特許文献１に開示された制振ラックと制振方法によれば、一対の棚受け本体に荷物が支えられている場合、制振ラックの振動エネルギーを荷物の振動エネルギーに変換する間に振動エネルギーを吸収散逸し、荷物を制振するとしている。   According to the vibration suppression rack and the vibration suppression method disclosed in Patent Document 1, when a load is supported on a pair of shelf support bodies, vibration energy is converted while the vibration energy of the vibration suppression rack is converted into vibration energy of the load. It is said that it will absorb and dissipate and dampen the luggage.

特開２００３−１１８８１８号公報JP 2003-118818 A

しかしながら、特許文献１に開示された制振ラックは、荷を支える一対の棚受け本体の両側に制振部材がそれぞれ設けられた構造である。
このため、制振部材の変形量は、地震により脚部から制振ラックが揺れた際に、荷がその場所に位置し続けようとする力（荷の慣性力）によらざるを得ず、荷の質量や、棚受け本体との摩擦係数によっては効果を発揮できないという問題がある。
また、特許文献１に開示された制振ラックと制振方法では、荷を支える一対の棚受け本体の両側に制振部材がそれぞれ設けられることから、製造コストが増大する。 However, the damping rack disclosed in Patent Document 1 has a structure in which damping members are provided on both sides of a pair of shelf support bodies that support a load.
For this reason, the amount of deformation of the damping member is inevitably dependent on the force (load inertial force) that keeps the load in place when the damping rack swings from the leg due to the earthquake. There is a problem that the effect cannot be exhibited depending on the mass of the load and the coefficient of friction with the shelf support body.
Further, in the vibration damping rack and the vibration damping method disclosed in Patent Document 1, since the vibration damping members are provided on both sides of the pair of shelf support bodies that support the load, the manufacturing cost increases.

本発明は上記の問題点に鑑みてなされたもので、本発明の目的は、地震時にワークを支える一対の支持部材を備えた架構同士において位相の異なる揺れを発生させ、制振部材による地震エネルギーの効率的な吸収を可能とする収容棚の制震構造の提供にある。   The present invention has been made in view of the above problems, and an object of the present invention is to generate vibrations having different phases between frames having a pair of support members that support a workpiece during an earthquake, and the seismic energy generated by the damping member. It is in the provision of the vibration control structure of the storage rack that enables efficient absorption of the storage.

上記の課題を解決するために、本発明は、柱部材と梁部材により囲まれた構面を有する一対の架構が、前記構面を互いに平行にして配設され、前記一対の架構の間にワークを収容可能とする架構空間が形成され、前記一対の架構における一方の前記架構は、前記架構空間へ向けて設置された第１支持部材を備え、前記一対の架構における他方の前記架構は、前記架構空間へ向けて設置され、前記第１支持部材と対向する第２支持部材を備え、前記第１支持部材および前記第２支持部材により前記ワークを支持する収容棚の制震構造において、前記第２支持部材に備えられ、前記ワークと前記第２支持部材との水平方向の相対変位を規制する変位規制部材と、前記一方の前記架構と前記他方の架構を連結する連結部材と、前記連結部材に設けた制振部材とを有することを特徴とする。   In order to solve the above-described problems, the present invention provides a pair of frames having a structure surface surrounded by a column member and a beam member, the structure surfaces being arranged in parallel to each other, and the pair of frames between the pair of frames. A frame space capable of accommodating workpieces is formed, and one of the frames in the pair of frames includes a first support member installed toward the frame space, and the other frame in the pair of frames is: In the vibration control structure of a storage shelf that is installed toward the frame space, includes a second support member that faces the first support member, and supports the workpiece by the first support member and the second support member, A displacement regulating member provided in a second support member for regulating a relative displacement in a horizontal direction between the workpiece and the second support member; a coupling member for coupling the one frame to the other frame; and the coupling Provided in the member And having a vibration member.

本発明では、収容棚において第１支持部材と第２支持部材により受承されるワークが存在する場合、収容棚が地震エネルギーを受けると、一方の架構および他方の架構ではそれぞれ揺れが生じる。
このとき、他方の架構側では、変位規制部材により第２支持部材に対するワークの変位が規制され易く、ワークは他方の架構の揺れとともに揺れ易い。
一方の架構側では、第１支持部材に対するワークの変位は積極的に規制されないため、ワークは第１支持部材に対して他方の架構の揺れに応じて変位する。
ワークと一体となって揺れ易い他方の架構は、負担する水平荷重の違いにより、一方の架構よりも揺れが大きくなることから、一方の架構と他方の架構は異なる位相の揺れを生じる。
このとき、一方の架構と他方の架構との間の連結部材に設けた制振部材が地震エネルギーを吸収し、収容棚の揺れを減衰する。
本発明によれば、第２支持部材に変位規制部材を設けることで、例えば、一方の架構および他方の架構が同じ構造であっても、ワークを利用して一方の架構と他方の架構に互いに異なる位相の揺れを生じさせることができ、制振部材による地震エネルギーの効率的な吸収が可能である。
また、既設の収容棚であっても、第２支持部材に変位規制部材を設けるとともに制振部材を設けてワークを搭載すれば、制震機能を収容棚に付加させることができる。
なお、ここでいう制震機能は構造物の揺れを積極的に抑制する機能を意味し、揺れに対抗する耐震機能とは区別される機能である。 In the present invention, when there is a work received by the first support member and the second support member in the storage shelf, if the storage shelf receives seismic energy, the one frame and the other frame are swayed.
At this time, on the other frame side, the displacement of the workpiece with respect to the second support member is easily regulated by the displacement regulating member, and the workpiece is easily shaken with the shaking of the other frame.
On one frame side, since the displacement of the workpiece with respect to the first support member is not positively regulated, the workpiece is displaced with respect to the first support member in accordance with the shaking of the other frame.
The other frame, which is easy to swing together with the workpiece, swings more than the other frame due to the difference in the horizontal load to be borne, so that one frame and the other frame have different phases.
At this time, the damping member provided in the connecting member between the one frame and the other frame absorbs the seismic energy and attenuates the shaking of the storage shelf.
According to the present invention, by providing the displacement regulating member on the second support member, for example, even if one frame and the other frame have the same structure, the one frame and the other frame are mutually connected using the workpiece. Different phase fluctuations can be generated and seismic energy can be efficiently absorbed by the damping member.
Moreover, even if it is an existing storage shelf, if a displacement control member is provided on the second support member and a vibration control member is provided and a workpiece is mounted, a vibration control function can be added to the storage shelf.
In addition, the seismic control function here is a function that actively suppresses the shaking of the structure, and is a function that is distinguished from the seismic function that resists the shaking.

また、上記の収容棚の制震構造において、前記変位規制部材は、前記ワークの前記第２支持部材に対する水平方向の相対変位を許容しない係止片とする構成としてもよい。
この場合、係止片が第２支持部材に対するワークの相対変位を許容しないため、第２支持部材を設けた他方の架構はワークと共に揺れる。
その結果、一方の架構の揺れと他方の架構の揺れとの位相差をより大きくすることができ、制震部材よる地震エネルギーの吸収をより効率的に行うことができる。 In the vibration control structure of the storage shelf, the displacement restricting member may be a locking piece that does not allow a horizontal relative displacement of the work with respect to the second support member.
In this case, since the locking piece does not allow relative displacement of the work with respect to the second support member, the other frame provided with the second support member swings together with the work.
As a result, the phase difference between the shaking of one frame and the shaking of the other frame can be increased, and the seismic energy can be absorbed more efficiently by the damping member.

また、上記の収容棚の制震構造において、前記一方の前記架構は、主柱部材と主梁部材により囲まれた主構面を有する主架構であり、前記他方の前記架構は、従属柱部材と従属梁部材により囲まれた従属構面を有し、前記主架構より変形しやすい従属架構である構成としてもよい。
この場合、ワークを利用して架構空間を形成する架構間に互いに異なる位相の揺れを生じさせるだけでなく、架構の構造上の相違により互いに異なる位相の揺れを生じさせることができる。
第２支持部材を設けた他方の架構は従属架構であるから、従属架構はワークと共により揺れ易く、主架構の揺れと従属架構の揺れとの位相差をさらに大きくすることができる。 Further, in the vibration control structure for the storage shelf, the one frame is a main frame having a main frame surface surrounded by a main column member and a main beam member, and the other frame is a dependent column member. It is good also as a structure which has a subordinate frame surrounded by the subordinate beam member, and is a subordinate frame which is easier to deform | transform than the said main frame.
In this case, it is possible not only to cause different phase fluctuations between the frames forming the frame space using the workpiece, but also to cause different phase fluctuations due to the structural differences of the frames.
Since the other frame provided with the second support member is a subordinate frame, the subordinate frame is more likely to swing with the work, and the phase difference between the main frame and the subordinate frame can be further increased.

また、本発明は、柱部材と梁部材により囲まれた構面を有する一対の架構が、前記構面を互いに平行にして配設され、前記一対の架構の間にワークを収容可能とする架構空間が形成され、前記一対の架構における一方の前記架構は、前記架構空間へ向けて設置された第１支持部材を備え、前記一対の架構における他方の前記架構は、前記架構空間へ向けて設置され、前記第１支持部材と対向する第２支持部材を備え、前記第１支持部材および前記第２支持部材により前記ワークを支持する収容棚の制震構造において、前記ワークと前記第１支持部材との間の摩擦係数は、前記ワークと前記第２支持部材との間の摩擦係数よりも小さく設定され、前記一方の前記架構と前記他方の架構を連結する連結部材と、前記連結部材に設けた制振部材とを有することを特徴とする。   Further, according to the present invention, a pair of frames having a structure surface surrounded by a column member and a beam member are disposed with the structure surfaces parallel to each other, and a structure that can accommodate a workpiece between the pair of frames. A space is formed, and one of the frames in the pair of frames includes a first support member installed toward the frame space, and the other frame of the pair of frames is installed toward the frame space. And a second support member facing the first support member, wherein the work and the first support member are arranged in a vibration control structure of a storage shelf that supports the work by the first support member and the second support member. Is set to be smaller than the friction coefficient between the workpiece and the second support member, and is provided in the connecting member for connecting the one frame to the other frame, and the connecting member Vibration damping member Characterized in that it.

本発明では、収容棚において第１支持部材と第２支持部材により受承されるワークが存在する場合、収容棚が地震エネルギーを受けると、一方の架構および他方の架構ではそれぞれ揺れが生じる。
ワークと第２支持部材との間の摩擦係数は、ワークと第１支持部材との間の摩擦係数よりも大きく設定されているから、ワークは第２支持部材とともに揺れ易く、第１支持部材に対して変位しやすい。
一方の架構と他方の架構が負担する水平荷重の違いにより、一方の架構の揺れよりも他方の架構の揺れが大きくなり、一方の架構と他方の架構は異なる位相の揺れを生じる。
このとき、一方の架構と他方の架構との間の連結部材に設けた制振部材が地震エネルギーを吸収し、収容棚の揺れを減衰する。
本発明によれば、ワークと第２支持部材との間の摩擦係数をワークと第１支持部材との間の摩擦係数よりも大きく設定することで、例えば、一方の架構および他方の架構が同じ構造であっても、ワークを利用して一方の架構と他方の架構に互いに異なる位相の揺れを生じさせることができ、制振部材による地震エネルギーの効率的な吸収が可能である。 In the present invention, when there is a work received by the first support member and the second support member in the storage shelf, if the storage shelf receives seismic energy, the one frame and the other frame are swayed.
Since the coefficient of friction between the workpiece and the second support member is set to be larger than the coefficient of friction between the workpiece and the first support member, the workpiece easily shakes together with the second support member, and the first support member On the other hand, it is easily displaced.
Due to the difference in the horizontal load borne by one frame and the other frame, the vibration of the other frame becomes larger than the vibration of one frame, and the one frame and the other frame have different phases.
At this time, the damping member provided in the connecting member between the one frame and the other frame absorbs the seismic energy and attenuates the shaking of the storage shelf.
According to the present invention, by setting the friction coefficient between the workpiece and the second support member to be larger than the friction coefficient between the workpiece and the first support member, for example, one frame and the other frame are the same. Even if it is a structure, it is possible to cause different phases of shaking in one frame and the other frame using a workpiece, and it is possible to efficiently absorb seismic energy by the damping member.

また、上記の収容棚の制震構造において、前記一方の前記架構は、主柱部材と主梁部材により囲まれた主構面を有する主架構であり、前記他方の前記架構は、従属柱部材と従属梁部材により囲まれた従属構面を有し、前記主架構より変形しやすい従属架構である。
この場合、ワークを利用して架構空間を形成する架構間に互いに異なる位相の揺れを生じさせるだけでなく、架構の構造上の相違により互いに異なる位相の揺れを生じさせることができる。
第２支持部材を設けた他方の架構は従属架構であるから、従属架構はワークと共により揺れ易く、主架構の揺れと従属架構の揺れとの位相差をさらに大きくすることができる。 Further, in the vibration control structure for the storage shelf, the one frame is a main frame having a main frame surface surrounded by a main column member and a main beam member, and the other frame is a dependent column member. And a subordinate frame surrounded by subordinate beam members, which is more easily deformed than the main frame.
In this case, it is possible not only to cause different phase fluctuations between the frames forming the frame space using the workpiece, but also to cause different phase fluctuations due to the structural differences of the frames.
Since the other frame provided with the second support member is a subordinate frame, the subordinate frame is more likely to swing with the work, and the phase difference between the main frame and the subordinate frame can be further increased.

本発明によれば、地震時にワークを支える一対の支持部材を備えた架構同士において位相の異なる揺れを発生させ、制振部材による地震エネルギーの効率的な吸収を可能とする収容棚の制震構造を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the vibration control structure of the storage shelf which generate | occur | produces the shaking from which a phase differs in frames provided with a pair of support member which supports a workpiece | work at the time of an earthquake, and enables efficient absorption of the earthquake energy by a damping member Can be provided.

The height from the connecting portion 37 to the upper end of the inclined surface 41 is set to a height that does not hinder the loading and unloading of the workpiece W by the stacker crane 13.
Since the locking piece 40 includes the inclined surface 41, when the work W is lowered when the work W is accommodated in the work accommodating space S, the inclined surface 41 causes the bottom portion of the work W to be moved to the second support member 25. It functions as a guide part to guide to.

大地震が発生し、主架構１５および従属架構２０の前後方向の振動（主構面１８および従属構面２３と平行な揺れ）が生じると、十分な強度が設定されている主架構１５と、主架構１５と比べると変形し易い従属架構２０には、互いに位相の異なる揺れが発生する。
剛性の大きい主架構１５では変形の小さい揺れであり、従属架構２０は外力に対して変形し易いため変形の大きい揺れとなる。
特に、収容棚１１の上部は下部と比べて揺れが大きくなる傾向がある。 Next, the vibration control effect of the storage shelf 11 according to this embodiment will be described.
In this embodiment, it is assumed that the workpiece W is accommodated in the workpiece accommodating space S for convenience of explanation.
The workpiece W is supported by the first support member 24 and the second support member 25 in the first frame space R1, and is supported by the pair of second support members 25 and 25 in the second frame space R2.
When a large earthquake occurs and vibrations in the front-rear direction of the main frame 15 and the sub frame 20 (shake parallel to the main frame 18 and the sub frame 23) occur, the main frame 15 having a sufficient strength, The sub-frame 20 that is easily deformed as compared with the main frame 15 generates vibrations having different phases.
The main frame 15 having high rigidity has a small deformation, and the sub frame 20 easily deforms with respect to an external force, resulting in a large deformation.
In particular, the upper part of the storage shelf 11 tends to swing more than the lower part.

上下方向において水平架材２６と水平架材２６との間に存在する複数のワーク収容空間Ｓでは、主柱部材１６における上側の水平架材２６と下側の水平架材２６との間の部位と、従属柱部材２１における上側の水平架材２６と下側の水平架材２６との間との変形は互いに異なる。
例えば、主柱部材１６における２、３段目のワーク収容空間Ｓに対応する部位は、従属柱部材２１における２、３段目のワーク収容空間Ｓに対応する部位と比べて変形は少ない。
同様に、主柱部材１６における４、５段目のワーク収容空間Ｓに対応する部位は、従属柱部材２１における４、５段目のワーク収容空間Ｓに対応する部位と比べて変形は少ない。 In a plurality of work accommodating spaces S existing between the horizontal frame member 26 and the horizontal frame member 26 in the vertical direction, a portion between the upper horizontal frame member 26 and the lower horizontal frame member 26 in the main pillar member 16. And the deformation between the upper horizontal member 26 and the lower horizontal member 26 in the dependent column member 21 are different from each other.
For example, the portion of the main pillar member 16 corresponding to the second and third stages of the work accommodation space S is less deformed than the portion of the dependent pillar member 21 corresponding to the second and third stages of the work accommodation space S.
Similarly, the portion of the main column member 16 corresponding to the fourth and fifth stages of the work accommodating space S is less deformed than the portion of the subordinate column member 21 corresponding to the fourth and fifth stages of the workpiece accommodating space S.

係止片４０を有する第２支持部材２５では、係止片４０により第２支持部材２５に対して変位が規制されるワークＷが、従属柱部材２１における第２支持部材２５と一体になって前後方向に揺れる。
ワークＷが前後方向に揺れるとき、ワークＷに生じる水平方向の荷重は、第１支持部材２４および第２支持部材２５がそれぞれ負担するが、第１支持部材２４が負担する水平荷重と第２支持部材２５が負担する水平荷重は異なる。
本実施形態では、係止片４０を有する第２支持部材２５が負担する水平荷重は、第１支持部材２４が負担する水平荷重よりも大きい。
従って、主柱部材１６における係止片４０を有する第２支持部材２５と対向する第１支持部材２４付近の部位は、従属柱部材２１における第２支持部材２５付近の部位と異なる位相にて揺れ、この従属柱部材２１より揺れは小さい。
第２支持部材２５とワークＷが一体となって大きく揺れ、さらに、第１支持部材２４では、第１支持部材２４とワークＷとの摩擦力以上の水平荷重がワークＷに作用する場合、ワークＷは第１支持部材２４に対して前後方向へ相対変位する。 In the second support member 25 having the locking piece 40, the workpiece W whose displacement is regulated with respect to the second support member 25 by the locking piece 40 is integrated with the second support member 25 in the dependent column member 21. Shake back and forth.
When the work W swings in the front-rear direction, the horizontal load generated on the work W is borne by the first support member 24 and the second support member 25, respectively, but the horizontal load borne by the first support member 24 and the second support The horizontal load borne by the member 25 is different.
In the present embodiment, the horizontal load borne by the second support member 25 having the locking piece 40 is larger than the horizontal load borne by the first support member 24.
Accordingly, the portion near the first support member 24 facing the second support member 25 having the locking piece 40 in the main column member 16 sways at a phase different from that of the portion near the second support member 25 in the dependent column member 21. The shaking is smaller than that of the dependent column member 21.
When the second support member 25 and the workpiece W are greatly shaken integrally, and the first support member 24 has a horizontal load greater than the frictional force between the first support member 24 and the workpiece W acting on the workpiece W, the workpiece W is displaced relative to the first support member 24 in the front-rear direction.

図７は、ワークＷが従属柱部材２１と一体となって距離ｄだけ前方へ変位するとともに、ワークＷが第１支持部材２４に対して距離ｄだけ前方へ相対変位した状態を示す。
ワークＷと従属柱部材２１は、一体となって前方へ変位するだけでなく、後方へも変位する。
また、ワークＷは、第１支持部材２４に対する前方への相対変位だけでなく、第１支持部材２４に対して後方へも相対変位する。
第１支持部材２４に対するワークＷの相対変位と、ワークＷと従属柱部材２１との一体となった変位により、図５に示すように、連結部材２９に設けたダンパー３５が変形される。
ダンパー３５が変形することにより地震エネルギーがダンパー３５に吸収され、ダンパー３５において熱エネルギーに変換される。
負担するワークＷの水平荷重の違いにより、ワークＷの従属柱部材２１と一体となった前後方向への変位が大きいほど、第１支持部材２４に対するワークＷの相対変位が大きくなる。
第１支持部材２４に対するワークＷの相対変位が大きいほど、ダンパー３５の変形も大きくなり、ダンパー３５による地震エネルギーの吸収も多くなる。 FIG. 7 shows a state in which the workpiece W is integrally displaced with the dependent column member 21 and moved forward by a distance d, and the workpiece W is relatively displaced forward by a distance d with respect to the first support member 24.
The workpiece W and the dependent column member 21 are displaced not only forward but also backward.
Further, the workpiece W is not only displaced forward relative to the first support member 24 but also displaced backward relative to the first support member 24.
As shown in FIG. 5, the damper 35 provided on the connecting member 29 is deformed by the relative displacement of the workpiece W with respect to the first support member 24 and the displacement in which the workpiece W and the dependent column member 21 are integrated.
When the damper 35 is deformed, the seismic energy is absorbed by the damper 35 and converted into heat energy by the damper 35.
Due to the difference in the horizontal load of the work W to be borne, the relative displacement of the work W with respect to the first support member 24 increases as the displacement in the front-rear direction integrated with the dependent column member 21 of the work W increases.
The greater the relative displacement of the workpiece W with respect to the first support member 24, the greater the deformation of the damper 35 and the greater the absorption of earthquake energy by the damper 35.

なお、本実施形態では、架構空間Ｒ２において第２支持部材２５にのみにより支持されるワークＷは、係止片４０による規制を受け架構空間Ｒ２を形成する従属架構２０と一体となって揺れる。
従って、架構空間Ｒ１において負担するワークＷの水平荷重に対して架構空間Ｒ２におけるワークＷの水平荷重が加算され、第２支持部材２５側の従属架構２０はより大きく揺れることができる。 In the present embodiment, the workpiece W supported only by the second support member 25 in the frame space R2 is shaken integrally with the subframe 20 that is restricted by the locking piece 40 and forms the frame space R2.
Therefore, the horizontal load of the workpiece W in the frame space R2 is added to the horizontal load of the workpiece W borne in the frame space R1, and the dependent frame 20 on the second support member 25 side can be shaken more greatly.

本実施形態の収容棚１１の制震構造は以下の作用効果を奏する。
（１）第１支持部材２４と第２支持部材２５により受承されるワークＷが存在する場合、収容棚１１が地震エネルギーを受けると、主架構１５および従属架構２０ではそれぞれ揺れが生じる。このとき、従属架構２０では、ワークＷが係止片４０により第２支持部材２５と一体となって従属架構２０とともに揺れる。ワークＷと一体となって揺れる従属架構２０では、負担するワークＷの水平荷重の違いにより、主架構１５よりも揺れが大きくなることから、主架構１５と従属架構２０は異なる位相の揺れを生じる。このため、主架構１５では、ワークＷが第１支持部材２４に対して従属架構２０の揺れに応じて変位する。このとき、連結部材２９に設けたダンパー３５が変形して地震エネルギーを吸収し、収容棚１１の揺れを減衰する。主架構１５と従属架構２０との間の連結部材２９にダンパー３５を設け、第２支持部材２５に係止片４０を設けることで、ワークＷを利用して主架構１５と従属架構２０に互いに異なる位相の揺れを生じさせることができ、ダンパー３５による地震エネルギーの効率的な吸収が可能である。 The vibration control structure of the storage shelf 11 of the present embodiment has the following effects.
(1) When there is a workpiece W received by the first support member 24 and the second support member 25, when the storage shelf 11 receives seismic energy, the main frame 15 and the subframe 20 are swayed. At this time, in the dependent frame 20, the work W is shaken together with the dependent frame 20 together with the second support member 25 by the locking piece 40. In the subordinate frame 20 that swings integrally with the work W, the main frame 15 and the subordinate frame 20 cause fluctuations of different phases because the vibration is larger than that of the main frame 15 due to the difference in the horizontal load of the work W to be borne. . For this reason, in the main frame 15, the workpiece W is displaced with respect to the first support member 24 in accordance with the shaking of the dependent frame 20. At this time, the damper 35 provided on the connecting member 29 is deformed to absorb the seismic energy and attenuate the shaking of the storage rack 11. By providing a damper 35 on the connecting member 29 between the main frame 15 and the sub frame 20 and providing a locking piece 40 on the second support member 25, the main frame 15 and the sub frame 20 can be connected to each other using the workpiece W. Different phase fluctuations can be generated, and the damper 35 can efficiently absorb the seismic energy.

（２）収容棚１１が主架構１５と従属架構２０との組み合わせにより構成されるから、ワークＷを利用して互いに異なる位相の揺れを複数の架構に生じさせるだけでなく、主架構１５と従属架構２０の構造上の相違を利用して、主架構１５と従属架構２０において互いに異なる位相の揺れを生じさせることができる。従って、主架構１５と従属架構２０の揺れの位相差をより大きくすることができる。 (2) Since the storage shelf 11 is constituted by a combination of the main frame 15 and the sub frame 20, the workpiece W is not only used to cause different phase fluctuations in a plurality of frames but also dependent on the main frame 15. By utilizing the structural difference of the frame 20, the main frame 15 and the sub frame 20 can cause different phase fluctuations. Therefore, the phase difference of shaking between the main frame 15 and the sub frame 20 can be further increased.

（３）第２支持部材２５とワークＷとの前後方向の相対変位が係止片４０により規制されるから、ワークＷと第１支持部材２４との相対変位が確実にダンパー３５に入力され、ダンパー３５を変形させることができる。従って、ダンパー３５の変形による地震エネルギーの確実で効率的な吸収が可能である。また、係止片４０が第２支持部材２５とワークＷとの前後方向の相対変位を確実に規制することから、第２支持部材２５が負担するワークＷの水平荷重を、第１支持部材２４が負担するワークＷの水平荷重よりも大きくすることができ、ワークＷを利用して主架構１５と従属架構２０に互いに異なる位相の揺れを確実に生じさせることができる。 (3) Since the relative displacement in the front-rear direction between the second support member 25 and the workpiece W is regulated by the locking piece 40, the relative displacement between the workpiece W and the first support member 24 is reliably input to the damper 35, The damper 35 can be deformed. Therefore, reliable and efficient absorption of seismic energy due to the deformation of the damper 35 is possible. Further, since the locking piece 40 reliably restricts the relative displacement in the front-rear direction between the second support member 25 and the work W, the horizontal load of the work W borne by the second support member 25 is used as the first support member 24. Therefore, the main frame 15 and the subordinate frame 20 can be surely caused to have different phases from each other.

（４）主架構１５の第１支持部材２４に対してワークＷを相対変位可能とするとともに、主架構１５よりも変形しやすい従属架構２０の第２支持部材２５に係止片４０を設けたことにより、ワークＷは従属架構２０と一体となって揺れる。このため、従属架構２０は主架構１５に対してより大きな揺れを発生させることができ、より効率的にダンパー３５に地震エネルギーを吸収させることができる。 (4) The workpiece W can be relatively displaced with respect to the first support member 24 of the main frame 15, and the locking piece 40 is provided on the second support member 25 of the subframe 20 that is more easily deformed than the main frame 15. As a result, the workpiece W shakes integrally with the subordinate frame 20. For this reason, the subordinate frame 20 can generate a greater shaking with respect to the main frame 15, and the damper 35 can absorb the seismic energy more efficiently.

（５）ダンパー３５を備える第１支持部材２４と係止片４０を備える第２支持部材２５を有するワーク収容空間Ｓに必ずワークＷが収容されていれば、収容棚１１の制震機能を最大限に活用することができる。従って、ダンパー３５を備える第１支持部材２４と係止片４０を備える第２支持部材２５を有するワーク収容空間Ｓに優先的にワークＷを収容すれば、収容可能なワークＷの数が限られている場合でも、収容棚１１の制震機能を発揮させることができる。 (5) If the workpiece W is always stored in the workpiece storage space S having the first support member 24 including the damper 35 and the second support member 25 including the locking piece 40, the vibration control function of the storage rack 11 is maximized. It can be used as much as possible. Therefore, if the work W is accommodated preferentially in the work accommodation space S having the first support member 24 having the damper 35 and the second support member 25 having the locking piece 40, the number of work W that can be accommodated is limited. Even if it is, the vibration control function of the storage shelf 11 can be exhibited.

（６）ワークＷは荷およびパレットを有するが、パレットのみのワークＷとしてもよい。この場合、第１支持部材２４と係止片４０を備える第２支持部材２５を有するワーク収容空間ＳにパレットのみのワークＷを収容しても収容棚１１の制震機能を発揮することができる。 (6) Although the workpiece W has a load and a pallet, the workpiece W may be a pallet-only workpiece W. In this case, the vibration control function of the storage shelf 11 can be exhibited even when the workpiece W having only the pallet is stored in the workpiece storage space S having the first support member 24 and the second support member 25 including the locking piece 40. .

（７）全てのワーク収容空間ＳにワークＷが収容されている状態であっても、収容棚１１に制震機能を発揮させることができる。従って、ワークＷのない空のワーク収容空間Ｓを積極的に設定する必要がなく、空のワーク収容空間Ｓを設定するためにスタッカクレーン１３による制御やその制御のためのプログラムが不要となる。 (7) Even if the workpieces W are accommodated in all the workpiece accommodating spaces S, the accommodation shelf 11 can exhibit the vibration control function. Therefore, there is no need to positively set an empty work accommodation space S without a work W, and control by the stacker crane 13 and a program for the control are not required to set the empty work accommodation space S.

（第２の実施形態）
次に、第２の実施形態に係る収容棚の制震構造について説明する。

本実施形態の収容棚１１では、第１の実施形態と同様に３組の対角線状のブレース２７が上中下に位置するように配置されている。
なお、スタッカクレーン１３によりワーク収容空間Ｓに対するワークＷの出し入れを行うことから、収容棚５１における前部の垂直構面にはブレース２７は設けられない。 The four main pillar members 16 and the upper and lower horizontal frames 26 that are provided in series at the front and rear of the storage shelf 51 form a vertical plane on the front and rear of the storage shelf 51.

In the storage shelf 11 of the present embodiment, three sets of diagonal braces 27 are arranged so as to be positioned in the upper, middle, and lower sides as in the first embodiment.
In addition, since the workpiece | work W is taken in / out by the stacker crane 13 with respect to the workpiece | work accommodation space S, the brace 27 is not provided in the vertical structure of the front part in the accommodation shelf 51. FIG.

図８に示すように、本実施形態の収容棚５１は、架構空間Ｒｂでは、主架構１５の最上部に水平斜材としての連結部材２８を備えているほか、２段目、４段目のワーク収容空間Ｓの下部において連結部材２８が備えられている。
連結部材２８は、第１架構空間Ｒｂにおいて水平に架設されている。
架構空間Ｒｂでは、連結部材２８は、前部の主柱部材１６と後部の主柱部材１６との間を連結する。
つまり、連結部材２８は、架構空間Ｒｂにおける主架構１５同士を連結する。
連結部材２８の長手方向は、主梁部材１７の長手方向に対して傾斜していることから、連結部材２８は主構面１８に対して傾斜している。 As shown in FIG. 8, the storage shelf 51 of the present embodiment includes a connecting member 28 as a horizontal diagonal member at the top of the main frame 15 in the frame space Rb, as well as the second and fourth stages. A connecting member 28 is provided in the lower part of the work accommodating space S.
The connecting member 28 is installed horizontally in the first frame space Rb.
In the frame space Rb, the connecting member 28 connects the front main column member 16 and the rear main column member 16.
That is, the connecting member 28 connects the main frames 15 in the frame space Rb.
Since the longitudinal direction of the connecting member 28 is inclined with respect to the longitudinal direction of the main beam member 17, the connecting member 28 is inclined with respect to the main construction surface 18.

本実施形態の収容棚１１における架構空間Ｒａでは、主架構１５の最上部にダンパー３５を備えた連結部材２９が設けられている。

次に、本実施形態に係る収容棚５１の制震作用について説明する。
収容棚５１にワークＷが全く収容されていない状態にて大地震が発生すると、収容棚５１の各主架構１５はほぼ同じ位相の揺れが発生する。
一方、一部又は全てのワーク収容空間ＳにワークＷが収容された状態にて大地震が発生すると、架構空間ＲａにおいてワークＷが収容されているワーク収容空間Ｓでは、第２支持部材２５側の主架構１５は、第１支持部材２４側の主架構１５よりも大きく揺れる。
つまり、係止片４０を備えた第２支持部材２５側の主架構１５と第１支持部材２４側の主架構１５とは互いに異なる位相の揺れを生じる。 Next, the vibration control action of the storage shelf 51 according to this embodiment will be described.
When a large earthquake occurs in a state where no work W is stored in the storage shelf 51, the main frames 15 of the storage shelf 51 are shaken with substantially the same phase.
On the other hand, when a large earthquake occurs in a state where the workpiece W is accommodated in a part or all of the workpiece accommodating spaces S, the second supporting member 25 side in the workpiece accommodating space S in which the workpiece W is accommodated in the frame space Ra. The main frame 15 swings more greatly than the main frame 15 on the first support member 24 side.
That is, the main frame 15 on the second support member 25 side provided with the locking piece 40 and the main frame 15 on the first support member 24 side cause different phase fluctuations.

その理由は、係止片４０を備えた第２支持部材２５側の主架構１５は、負担するワークＷの水平荷重の違いにより、係止片４０によりワークＷと一体となって揺れ、第１支持部材２４側の主架構１５では、ワークＷが第１支持部材２４に対して相対変位するためである。
従って、架構空間Ｒａにおいて係止片４０を備えた第２支持部材２５側の主架構１５は、第１支持部材２４側の主架構１５よりも大きく揺れる。
第２支持部材２５側の主架構１５と第１支持部材２４側の主架構１５とは互いに異なる位相の揺れを生じることから、架構空間Ｒａにおいて配設された連結部材２９のダンパー３５は揺れに応じて変形し、変形に応じて地震エネルギーを吸収し、熱エネルギーに変換する。 The reason is that the main frame 15 on the second support member 25 side provided with the locking piece 40 swings integrally with the work W by the locking piece 40 due to the difference in the horizontal load of the work W to be borne, and the first This is because the workpiece W is relatively displaced with respect to the first support member 24 in the main frame 15 on the support member 24 side.
Therefore, the main frame 15 on the second support member 25 side having the locking piece 40 in the frame space Ra swings more greatly than the main frame 15 on the first support member 24 side.
Since the main frame 15 on the second support member 25 side and the main frame 15 on the first support member 24 side have different phases, the damper 35 of the connecting member 29 disposed in the frame space Ra is shaken. It deforms accordingly, absorbs seismic energy according to the deformation, and converts it into thermal energy.

なお、本実施形態では、架構空間Ｒｂにおいて第２支持部材２５にのみにより支持されるワークＷは、係止片４０による規制を受け架構空間Ｒｂを形成する主架構１５と一体となって揺れる。
従って、架構空間Ｒａにおいて負担するワークＷの水平荷重に対して架構空間ＲｂにおけるワークＷの水平荷重が加算され、第２支持部材２５側の主架構１５はより大きく揺れることができる。 In the present embodiment, the workpiece W supported only by the second support member 25 in the frame space Rb is shaken integrally with the main frame 15 that is restricted by the locking piece 40 and forms the frame space Rb.
Therefore, the horizontal load of the work W in the frame space Rb is added to the horizontal load of the work W borne in the frame space Ra, and the main frame 15 on the second support member 25 side can be shaken more greatly.

本実施形態によれば、主架構１５により構成され、従属架構を備えない収容棚５１であっても、負担するワークＷの水平荷重の違いにより、互いに隣り合う主架構１５について異なる位相の揺れを生じさせることができ、連結部材２９が備えるダンパー３５による地震エネルギーの吸収を図ることができる。
また、既存の収容棚が第１支持部材２４と第２支持部材２５を備える構成であれば、第２支持部材２５に係止片４０を追加し、架構空間Ｒａにダンパー３５を備えた連結部材２９を配設することにより、既存の収容棚の制震性能を向上させることができる。 According to the present embodiment, even if the storage shelf 51 is configured by the main frame 15 and does not have a subordinate frame, different phases of the main frame 15 adjacent to each other are shaken due to the difference in the horizontal load of the work W to be borne. It is possible to cause the earthquake energy to be absorbed by the damper 35 provided in the connecting member 29.
Moreover, if the existing storage shelf is the structure provided with the 1st support member 24 and the 2nd support member 25, the connection piece which added the latching piece 40 to the 2nd support member 25, and was equipped with the damper 35 in frame space Ra. By arranging 29, the vibration control performance of the existing storage shelf can be improved.

（第３の実施形態）
次に、第３の実施形態に係る収容棚の制震構造について説明する。
本実施形態は、従属架構が備える第２支持部材が変位規制部材を備えず、主架構が備える第１支持部材とワークとの間との摩擦係数が、第２支持部材とワークとの摩擦係数より小さく設定された収容棚である点で第１の実施形態と異なる。
また、本実施形態の収容棚における主架構および従属架構の基本構成は、第１の実施形態と同じであるため、第１の実施形態の説明を援用し、符号を共通して用いる。 (Third embodiment)
Next, the vibration control structure of the storage shelf according to the third embodiment will be described.
In this embodiment, the second support member included in the subframe does not include the displacement restricting member, and the friction coefficient between the first support member and the workpiece included in the main frame is the friction coefficient between the second support member and the workpiece. This is different from the first embodiment in that the storage shelf is set smaller.
Moreover, since the basic structure of the main frame and the subordinate frame in the storage shelf of this embodiment is the same as that of the first embodiment, the description of the first embodiment is used and the reference numerals are used in common.

図９に示す本実施形態の収容棚６１では、第１の実施形態と同様に、主架構１５に第１支持部材２４が設けられ、従属架構２０に第２支持部材２５が設けられている。
ワークＷと第１支持部材２４との間の摩擦係数は、ワークＷと第２支持部材２５との間の摩擦係数よりも小さく設定されている。
図１０に示すように、本実施形態の第１支持部材２４は、第１の実施形態と同様に、腕部３６および接続部３７を有する。
ワークＷを支持する腕部３６および接続部３７の受け面となる上面には、ワークＷと第１支持部材との摩擦係数を低減する摩擦低減フィルム６２がそれぞれ貼着されている。
一方、第２支持部材２５は、第１の実施形態と同様に、腕部３８および接続部３９を有するが、係止片４０は備えられていない。 In the storage shelf 61 of the present embodiment shown in FIG. 9, the first support member 24 is provided on the main frame 15 and the second support member 25 is provided on the dependent frame 20, as in the first embodiment.
The coefficient of friction between the workpiece W and the first support member 24 is set to be smaller than the coefficient of friction between the workpiece W and the second support member 25.
As shown in FIG. 10, the first support member 24 of the present embodiment has an arm portion 36 and a connection portion 37 as in the first embodiment.
Friction reducing films 62 for reducing the friction coefficient between the workpiece W and the first support member are attached to the upper surfaces serving as the receiving surfaces of the arm portion 36 and the connection portion 37 that support the workpiece W, respectively.
On the other hand, the 2nd support member 25 has the arm part 38 and the connection part 39 similarly to 1st Embodiment, However, The latching piece 40 is not provided.

ワークＷは、第１支持部材２４および第２支持部材２５により支持される。
本実施形態では、ワークＷと第１支持部材２４との間の摩擦係数は、摩擦低減フィルム６２によりワークＷと第２支持部材２５との間の摩擦係数よりも小さく設定されている。
このため、ワークＷと第１支持部材２４との間の摩擦力は、ワークＷと第２支持部材２５との間の摩擦力よりも小さい。 The workpiece W is supported by the first support member 24 and the second support member 25.
In the present embodiment, the friction coefficient between the work W and the first support member 24 is set to be smaller than the friction coefficient between the work W and the second support member 25 by the friction reduction film 62.
For this reason, the frictional force between the workpiece W and the first support member 24 is smaller than the frictional force between the workpiece W and the second support member 25.

本実施形態では、大地震が発生し前後方向の揺れが生じると、ワークＷとの摩擦力が第２支持部材２５の摩擦力よりも小さい第１支持部材２４側では、ワークＷの第１支持部材２４に対する変位は、第２支持部材２５に対する変位よりも大きくなる。
従って、第１架構空間Ｒ２におけるワークＷは、従属柱部材２１における第２支持部材２５と一体になって前後方向に揺れ易くなる。
ワークＷが前後方向に揺れるとき、ワークＷに生じる水平方向の荷重は、第１支持部材２４および第２支持部材２５がそれぞれ負担する。
本実施形態では、ワークＷと第１支持部材との摩擦力、ワークＷと第２支持部材との摩擦力との相違から、第１支持部材２４が負担する水平荷重と第２支持部材２５が負担する水平荷重は異なる。 In the present embodiment, when a large earthquake occurs and shaking in the front-rear direction occurs, the first support member 24 side where the friction force with the workpiece W is smaller than the friction force of the second support member 25 is the first support of the workpiece W. The displacement with respect to the member 24 is larger than the displacement with respect to the second support member 25.
Therefore, the work W in the first frame space R2 is integrated with the second support member 25 in the dependent column member 21 and easily shakes in the front-rear direction.
When the workpiece W swings in the front-rear direction, the first support member 24 and the second support member 25 bear the horizontal load generated on the workpiece W, respectively.
In the present embodiment, due to the difference between the frictional force between the workpiece W and the first support member and the frictional force between the workpiece W and the second support member, the horizontal load borne by the first support member 24 and the second support member 25 are The horizontal load to be borne is different.

ワークＷとの摩擦力が第１支持部材２４よりも大きい第２支持部材２５が負担する水平荷重は、第１支持部材２４が負担する水平荷重よりも大きい。
従って、第１支持部材２４を備えた主架構１５は、第２支持部材２５を備えた従属架構２０と異なる位相にて揺れ、主架構１５の揺れは従属架構２０の揺れよりも小さい。
ワークＷの水平荷重の負担が大きい第２支持部材２５側では、第１支持部材２４側に対してワークＷと一体になるように揺れる。 The horizontal load borne by the second support member 25 whose frictional force with the workpiece W is greater than that of the first support member 24 is greater than the horizontal load borne by the first support member 24.
Therefore, the main frame 15 including the first support member 24 swings at a phase different from that of the sub frame 20 including the second support member 25, and the main frame 15 swings less than the sub frame 20.
On the second support member 25 side where the horizontal load of the workpiece W is large, the workpiece W swings so as to be integrated with the workpiece W relative to the first support member 24 side.

主架構１５と従属架構２０との相対変位により、連結部材２９に設けたダンパー３５が変形され、ダンパー３５が変形することにより地震エネルギーがダンパー３５に吸収され、ダンパー３５において熱エネルギーに変換される。
負担するワークＷの水平荷重の違いにより、第１支持部材２４に対するワークＷの相対変位が大きくなるが、第１支持部材２４に対するワークＷの相対変位が大きいほど、ダンパー３５の変形も大きくなり、ダンパー３５による地震エネルギーの吸収も多くなる。 Due to the relative displacement between the main frame 15 and the subframe 20, the damper 35 provided on the connecting member 29 is deformed, and when the damper 35 is deformed, the seismic energy is absorbed by the damper 35 and converted into heat energy at the damper 35. .
The relative displacement of the work W with respect to the first support member 24 increases due to the difference in the horizontal load of the work W to be borne, but the greater the relative displacement of the work W with respect to the first support member 24, the greater the deformation of the damper 35. Absorption of earthquake energy by the damper 35 increases.

本発明は、上記の実施形態に限定されるものではなく発明の趣旨の範囲内で種々の変更が可能であり、例えば、次のように変更してもよい。   The present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the gist of the invention. For example, the following modifications may be made.

○ 上記の実施形態では、自動倉庫における収容棚に本発明の収容棚の制震構造を適用した例であったが、自動倉庫以外の収容棚であってもよい。
○ 上記の実施形態では、制振部材として粘弾性材料であるゴム系材料によるダンパーを用いたが、制振部材は粘弾性材料のダンパーに代えて、例えば、前後方向に伸縮するオイルダンパーを用いてもよい。制振部材がオイルダンパーの場合、オイルの抵抗を利用して振動を減衰することができる。この場合も粘弾性材料のダンパーと同等の作用効果を奏する。
○ 上記の第１、第２の実施形態では、変位規制部材として金属板の打ち抜きにより形成された係止片としたが、変位規制手段は第２支持部材に対するワークの前後方向の変位を規制することができる構成であればよく、変位規制部材の具体的構成は特に制限されない。また、変位規制部材は、係止片のように、第２支持部材に対するワークの相対移動を完全に規制する場合だけでなく、第２支持部材に対するワークの相対移動を不完全に規制する場合であってもよく、少なくとも、第２支持部材が第１支持部材よりもワークの水平荷重を負担することができるように相対移動の規制を図ることができればよい。
○ 第２の実施形態では、従属架構を備えず主架構を備えた収容棚とし、係止片を設けた第２支持部材が互いに隣り合う架構空間Ｒｂを形成したがこれに限定されない。例えば、第１支持部材２４および第２支持部材２５によりワークＷが支持される架構空間Ｒａのみを形成するように、第１支持部材を備えた主架構１５と、係止片４０を備えた第２支持部材を備えた主架構１５を交互に配設し、さらに、主架構１５と従属架構２０との間にダンパー３５付きの連結部材２９を備えた収容棚としてもよい。この場合でも、ワークＷを収容される架構空間Ｒａを構成する一対の主架構１５において互いに位相の異なる揺れを生じることができる。
○ 第３の実施形態では、第１支持部材とワークとの間との摩擦係数が、第２支持部材とワークとの摩擦係数より小さく設定するために、摩擦低減フィルムを第１支持部材に貼着したが、これに限定されない。第１支持部材とワークとの間との摩擦係数は、第２支持部材とワークとの摩擦係数より相対的に小さく設定すればよい。例えば、第１支持部材には何も設けず、ワークと第２支持部材との摩擦係数が第１支持部材の摩擦係数よりも大きくなるように、第２支持部材におけるワークの支持面を粗面に形成し、第１支持部材とワークとの間との摩擦係数を第２支持部材とワークとの摩擦係数より相対的に小さく設定してもよい。また、第１支持部材に摩擦低減フィルムを設けるとともに、ワークと第２支持部材摩擦係数を大きくするためのフィルムを併用してもよい。また、摩擦係数を低減又は増大させるためのフィルムを用いるほかに、第１支持部材の鏡面加工又は第２支持部材の粗面加工により摩擦係数の低減又は増大を図るようにしてもよい。 In the above-described embodiment, the vibration control structure of the storage shelf of the present invention is applied to the storage shelf in the automatic warehouse, but a storage shelf other than the automatic warehouse may be used.
In the above embodiment, a damper made of a rubber-based material, which is a viscoelastic material, is used as the damping member, but the damping member uses, for example, an oil damper that expands and contracts in the front-rear direction instead of the damper of the viscoelastic material. May be. When the damping member is an oil damper, vibration can be damped by utilizing the resistance of oil. In this case, the same effect as the damper of the viscoelastic material can be obtained.
In the above first and second embodiments, the displacement regulating member is a locking piece formed by punching a metal plate, but the displacement regulating means regulates the displacement of the workpiece in the front-rear direction with respect to the second support member. The specific configuration of the displacement regulating member is not particularly limited. Further, the displacement restricting member is not only for completely restricting the relative movement of the work with respect to the second support member, as in the case of the locking piece, but for when incompletely restricting the relative movement of the work with respect to the second support member. It is sufficient that at least the second support member can regulate the relative movement so that the second support member can bear the horizontal load of the workpiece more than the first support member.
In the second embodiment, the housing shelf is provided with the main frame without the sub frame and the second support member provided with the locking pieces forms the frame space Rb adjacent to each other. However, the present invention is not limited to this. For example, the main frame 15 provided with the first support member and the first piece provided with the locking piece 40 so as to form only the frame space Ra in which the work W is supported by the first support member 24 and the second support member 25. The main frame 15 provided with two support members may be alternately arranged, and a storage shelf including a connecting member 29 with a damper 35 between the main frame 15 and the sub frame 20 may be used. Even in this case, the pair of main frames 15 constituting the frame space Ra in which the workpiece W is accommodated can be shaken with different phases.
○ In the third embodiment, in order to set the friction coefficient between the first support member and the workpiece to be smaller than the friction coefficient between the second support member and the workpiece, the friction reduction film is pasted on the first support member. I wore it, but it is not limited to this. The coefficient of friction between the first support member and the work may be set relatively smaller than the coefficient of friction between the second support member and the work. For example, nothing is provided on the first support member, and the work support surface of the second support member is rough so that the coefficient of friction between the work and the second support member is greater than the coefficient of friction of the first support member. The friction coefficient between the first support member and the workpiece may be set to be relatively smaller than the friction coefficient between the second support member and the workpiece. Moreover, while providing a friction reduction film in a 1st supporting member, you may use together the film for enlarging a workpiece | work and a 2nd supporting member friction coefficient. In addition to using a film for reducing or increasing the friction coefficient, the friction coefficient may be reduced or increased by mirror finishing of the first support member or roughening of the second support member.
