【産業上の利用分野】[Industrial applications]

本考案は天井レールの交差部へ移動壁の吊車が侵入する場合、該吊車が交差部 にて横振れしないようにした誘導装置に関するものである。 The present invention relates to a guide device for preventing a suspension vehicle from swinging laterally at an intersection when a suspension vehicle on a moving wall enters the intersection of ceiling rails.

【0002】[0002]

【従来の技術】[Prior art]

移動壁を配列して間仕切りを構成する場合、該移動壁の上端には吊車が取着さ れ、該吊車は天井レールに内装されて移動することが出来る。よって、移動壁は 吊車に吊設された状態で天井レールに沿って移動し、所定の場所に配列され、ま た不必要な場合には部屋の片隅に設けた収納部に収納される。 When the moving walls are arranged to form a partition, a suspension vehicle is attached to the upper end of the moving wall, and the suspension vehicle can be moved by being installed in a ceiling rail. Therefore, the moving wall moves along the ceiling rail while being suspended from the suspension vehicle, is arranged in a predetermined place, and is housed in a storage unit provided at one corner of the room when unnecessary.

【0003】 ところで、このように移動壁を所定の場所へ移動させるためには、天井レール は単に一直線を成しているのみならず、T字型や十字型にクロスした交差部を所 々に有している。したがって、吊車はこれら各交差部を通過して所定の場所へ移 動することになるが、該交差部へ侵入した吊車は多少横振れをして交差部の角に 衝突する等し、スムーズな通過を行い得ないのが実状である。吊車の型式にも色 々あって、垂直車輪を取着した型式の吊車は上記のような横振れ現象はほとんど 発生しないが、水平車輪型式の吊車において著しい。By the way, in order to move the moving wall to a predetermined place in this way, the ceiling rail is not only a straight line, but also T-shaped or cross-shaped crossed portions are sometimes found. Have Therefore, the suspension vehicle will move to a predetermined place after passing through each of these intersections, but the suspension vehicle that has entered the intersection will shake slightly and collide with the corners of the intersection, resulting in a smooth movement. The reality is that it cannot be passed. There are various types of suspension vehicles, and the type of suspension vehicle to which the vertical wheels are attached hardly causes the above-mentioned lateral vibration phenomenon, but it is remarkable in the suspension vehicle of the horizontal wheel type.

【0004】 図6は従来から使用されている2層水平車輪型式の吊車であるが、天井レール (イ) には上走行片(ロ) と下走行片(ハ) を水平に突出し、上・下走行片(ロ) 、(ハ) の走行面は傾斜していて、上車輪(ニ) 及び下車輪(ホ) の下端外周が接触している 。上下車輪(ニ) 、(ホ) は外周が接触することで互いに反対方向にバランスして回 転し、吊車は移動するが、交差部では車輪の外側をガイドするものがなく、特に 該交差部レールは鋳造加工品が用いられることもあって、その加工精度は悪く、 そのために上・下車輪(ニ) 、(ホ) のいずれかが走行面に接しない場合が発生する 。すなわち、片当り状態となる。FIG. 6 shows a two-layer horizontal wheel type suspension vehicle that has been conventionally used. An upper traveling piece (b) and a lower traveling piece (c) are horizontally projected on the ceiling rail (a), and The traveling surfaces of the lower traveling pieces (b) and (c) are inclined, and the lower end outer circumferences of the upper wheel (d) and the lower wheel (e) are in contact with each other. The upper and lower wheels (d) and (e) rotate in balance with each other in the opposite directions due to the contact of the outer peripheries, and the suspension vehicle moves, but there is no guide to the outside of the wheels at the intersection, especially at the intersection. Since the rails are cast products, the machining accuracy is poor, and therefore the upper / lower wheels (d) or (e) may not come into contact with the running surface. That is, it is a one-sided contact state.

【0005】 このように、片方の車輪(ニ) 又は(ホ) のみが走行片の走行面に接する場合、吊 車は直進することが出来ずして、接触している方向へ横振れする。上・下車輪(ニ ) 、(ホ) が共に接していても、走行面との間の接触圧が違う場合も同じように直 進不能となり、交差部へ侵入した吊車は該交差部の中心に向って進むことが出来 ない。As described above, when only one wheel (d) or (e) contacts the traveling surface of the traveling piece, the suspension vehicle cannot move straight and shakes laterally in the contacting direction. Even if the upper and lower wheels (d) and (e) are in contact with each other, if the contact pressure with the running surface is different, the vehicle will not be able to go straight, and the suspended vehicle that has entered the intersection will be in the center of the intersection. Can't move toward.

【0006】 図7は吊車の吊りボルト(ヘ) の軌跡を表わしているが、交差部(ト) へ侵入した 吊車は左方向へ横振れし、角(チ) に吊りボルト(ヘ) が衝突してから再びガイド溝 (リ) へ入り、該ガイド溝(リ) を直進移動する。このような軌跡は前記図6の上車 輪(ニ) が上走行片(ロ) の走行面に接しておらず、下車輪(ホ) のみにて支持してい る場合に発生する現象で、下車輪(ホ) は走行面との接触点を中心として回転する ことにより、同図のような左方向へ湾曲した軌跡を呈す。逆に下車輪(ホ) が接触 せず、上車輪(ニ) のみが走行面と接するならば、右方向へ横振れする。FIG. 7 shows the locus of the suspension bolt (f) of the suspension vehicle. The suspension vehicle that entered the intersection (g) laterally swings to the left, and the suspension bolt (f) collides with the corner (h). After that, it enters the guide groove (i) again and moves straight through the guide groove (i). Such a locus is a phenomenon that occurs when the upper wheel (d) in Fig. 6 is not in contact with the traveling surface of the upper traveling piece (b) and is supported only by the lower wheel (e). By rotating the lower wheel (e) around the point of contact with the running surface, a locus curved to the left as shown in the figure is exhibited. On the other hand, if the lower wheel (e) does not contact and only the upper wheel (d) contacts the running surface, it will shake to the right.

SUMMARY OF THE INVENTION The problems to be solved by the present invention are these problems, and provide a guiding device for a hanging vehicle that allows the hanging vehicle to enter the center of an intersection without lateral swing and improve straightness.

【課題を解決するための手段】[Means for Solving the Problems]

本考案の吊車誘導装置は天井レールの交差部中心へ吊車を導くようにしたもの であり、天井レールの交差部には誘導溝を形成している。ここで吊車は2層水平 車輪にて構成され、該吊車の上端には凸片を突出している。ここで凸片の形状は 特に限定しないが、該凸片は上記誘導溝に遊嵌するため、誘導溝の断面形状にな じむことのできる形状とする。誘導溝は交差部にのみ形成すればよく、その他の 天井レールでは水平車輪が側壁にてガイドされるため不必要であるが、該交差部 を別部材を用いないで天井レールを突き合わせて構成する場合には、天井レール 自体に誘導溝を形成する。そして、この誘導溝の幅は少なくとも吊りボルトをガ イドするガイド溝幅より小さくしている。以下、本考案に係る実施例を図面に基 づいて詳細に説明する。 The hoisting vehicle guidance device of the present invention is designed to guide the hoisting vehicle to the center of the intersection of the ceiling rails, and a guidance groove is formed at the intersection of the ceiling rails. Here, the suspension vehicle is composed of two-layer horizontal wheels, and a protruding piece projects from the upper end of the suspension vehicle. Here, the shape of the convex piece is not particularly limited, but since the convex piece is loosely fitted in the guide groove, the shape is such that it can conform to the cross-sectional shape of the guide groove. It is unnecessary to form the guide groove only at the intersection, and it is unnecessary in other ceiling rails because the horizontal wheels guide the horizontal wheels, but the intersection is constructed by abutting the ceiling rails without using a separate member. In some cases, guide grooves are formed on the ceiling rail itself. The width of the guide groove is at least smaller than the width of the guide groove that guides the suspension bolt. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

【0009】[0009]

【実施例】【Example】

図1は本考案の吊車誘導装置を示す実施例である。吊車1は上車輪2と下車輪 3が所定の間隔をおいて水平に軸支され、下方へは吊りボルト4を垂下し、該吊 りボルト4には移動壁(図示なし)が連結される。一方の天井レール5は側壁6 、6から上走行片7と下走行片8をそれぞれ水平に突出し、上・下走行片7、8 は僅かに傾斜した走行面を形成し、上・下車輪2、3の下端外周はこれら上・下 走行片7、8の走行面に接している。吊車1が移動すれば上・下車輪2、3はそ れぞれ反対方向にバランスして回転し、吊りボルト4はガイド溝9を動く。 FIG. 1 is an embodiment showing a hoisting vehicle guiding device of the present invention. An upper wheel 2 and a lower wheel 3 of a suspension vehicle 1 are horizontally supported at a predetermined interval, a suspension bolt 4 is suspended downward, and a moving wall (not shown) is connected to the suspension bolt 4. . One of the ceiling rails 5 horizontally projects the upper traveling piece 7 and the lower traveling piece 8 from the side walls 6 and 6, respectively, and the upper and lower traveling pieces 7 and 8 form a slightly inclined traveling surface. The outer circumference of the lower end of 3 is in contact with the running surfaces of these upper and lower running pieces 7, 8. When the suspension vehicle 1 moves, the upper and lower wheels 2 and 3 rotate in balance in opposite directions, and the suspension bolt 4 moves in the guide groove 9.

【0010】 そして天井レール5の交差部上板10には誘導溝11が形成され、この誘導溝 11には吊車1の上端に突出した凸片12が遊嵌している。交差部は他の直線レ ールとは別部材として鋳造加工され、十字型にクロスした交差部であるならば均 等に4分割した部品として鋳造したものを組合わせたもので、直線レール部に接 続して交差部を構成している。上記誘導溝11は直線レール部にはなく、交差部 にのみ形成され、これは吊りボルト4が移動するためのガイド溝9と同一方向に 設けている。A guide groove 11 is formed in the upper plate 10 at the intersection of the ceiling rail 5, and a convex piece 12 protruding from the upper end of the suspension vehicle 1 is loosely fitted in the guide groove 11. The intersecting part is cast as a separate member from other linear rails, and if it is a cross-shaped intersecting part, it is a combination of parts that are cast as four equally divided parts. To form an intersection. The guide groove 11 is not formed in the linear rail portion but is formed only in the intersection portion, which is provided in the same direction as the guide groove 9 for moving the suspension bolt 4.

【0011】 上記凸片12は誘導溝11に遊嵌して移動することが出来、該誘導溝11の幅 は上記ガイド溝9の幅に比べて小さく、また、誘導溝11に遊嵌する凸片12と の間には大きな隙間を残していない。上記凸片12はベアリングを用いて構成し 、誘導溝11の内側面に当接するならば転がり移動することになるが、該交差部 での吊車1の横振れを抑制する。The convex piece 12 can be loosely fitted and moved in the guide groove 11, the width of the guide groove 11 is smaller than the width of the guide groove 9, and the convex piece 12 is loosely fitted in the guide groove 11. No large gap is left between the strip 12 and the strip 12. The convex piece 12 is formed by using a bearing, and if it comes into contact with the inner surface of the guide groove 11, it will roll and move, but it suppresses lateral shake of the suspension vehicle 1 at the intersection.

【0012】 すなわち、前記図6に示すように、吊りボルト(ヘ) がガイド溝に遊嵌している 間は、該ガイド溝に拘束されるため吊車の振れはほとんどないが、この振れはガ イド溝が切れてクロスしている箇所で生じる訳で、該ガイド溝の幅を小さくする ならば、この振れも小さくなる。しかし、実際には移動壁を吊設するに必要な吊 りボルト(ヘ) の太さがあって、該吊りボルト(ヘ) を遊嵌するためのガイド溝はあ る程度の溝幅となってしまう。That is, as shown in FIG. 6, while the suspension bolt (f) is loosely fitted in the guide groove, it is restrained by the guide groove, so that there is almost no runout of the hoist vehicle, but this runout does not occur. This occurs at the position where the id groove is cut and crosses, and if the width of the guide groove is reduced, this deflection also becomes small. However, in reality, the suspension bolt (f) is thick enough to suspend the moving wall, and the guide groove for loosely fitting the suspension bolt (f) has a certain groove width. Will end up.

【0013】 本考案の誘導溝11及び凸片12は移動壁を吊設することに関与せず、したが って、誘導溝11の幅を小さくすることが出来、その分だけ吊車1の振れは抑制 される。図2は本考案の吊車の誘導装置を備えた場合の吊りボルト4の軌跡を表 わしている。同図のLはガイド溝幅を、また、Mは誘導溝幅を示しており、小幅 の誘導溝11に遊嵌している凸片12は、勿論、同図のごとく振れは生じるが、 その振幅はいたって小さくなる。このことは吊車の直進移動がスムーズに行われ ることに結び付く。The guide groove 11 and the convex piece 12 of the present invention are not involved in suspending the moving wall, and therefore, the width of the guide groove 11 can be reduced, and the swinging of the suspension vehicle 1 is correspondingly reduced. Is suppressed. FIG. 2 shows the locus of the suspension bolt 4 in the case where the suspension vehicle guiding device of the present invention is provided. In the figure, L indicates the guide groove width, and M indicates the guide groove width. Of course, the convex piece 12 loosely fitted in the guide groove 11 having a small width has a runout as shown in the figure, but The amplitude is very small. This leads to the smooth straight movement of the suspension vehicle.

【0014】 ところで、図1に示した実施例では、上記凸片12としてベアリングを用いて いるが、図3に示すように円柱状の凸片12であってもよい。また、図4、図5 は本考案の他の実施例であって、図4では凸片12として半球を用い、誘導溝1 1の断面は半円形としている。図5の凸片12は円錐形とし、誘導溝11の断面 は三角形となっている。このように、上記凸片12及び誘導溝11の形状は限定 しない。By the way, in the embodiment shown in FIG. 1, a bearing is used as the convex piece 12, but a cylindrical convex piece 12 may be used as shown in FIG. 4 and 5 show another embodiment of the present invention. In FIG. 4, a hemisphere is used as the convex piece 12, and the guide groove 11 has a semicircular cross section. The convex piece 12 in FIG. 5 has a conical shape, and the guide groove 11 has a triangular cross section. As described above, the shapes of the convex piece 12 and the guide groove 11 are not limited.

【0015】 一方、天井レール5の交差部を別部材として構成し、該交差部に直線レールを 連結するのが一般的であるが、直線レールを互いに突き合わせて交差部を形成す る場合もある。したがって、このような場合には直線レールそのものに上記誘導 溝を押出し成形してしまう。以上述べたように、本考案の吊車誘導装置は天井レ ールの交差部上板に細幅の誘導溝を形成し、吊車には該誘導溝に遊嵌する凸片を 突出したものであり、次のような効果を得ることが出来る。On the other hand, it is common to construct the intersection of the ceiling rails 5 as a separate member and connect the straight rails to the intersection, but there are also cases where the straight rails are butted against each other to form the intersection. . Therefore, in such a case, the guide groove is extruded on the straight rail itself. As described above, the hoisting vehicle guiding device of the present invention is one in which a narrow guiding groove is formed in the upper plate at the intersection of the ceiling rail, and the hoisting vehicle is provided with a protruding piece that is loosely fitted in the guiding groove. , The following effects can be obtained.

【0016】[0016]

【考案の効果】[Effect of device]

本考案の誘導装置を備えることで、吊車は天井レールの交差部をスムーズに通 過することが出来、その直進性が大きく向上する。すなわち、細幅の誘導溝に遊 嵌する吊車の凸片は、該吊車の振れを抑制し、移動壁は各交差部にて吊りボルト がガイド溝の角に当って引っ掛かることもなく、移動操作が滑らかとなる。 By providing the guidance device of the present invention, the suspension vehicle can smoothly pass through the intersection of the ceiling rails, and the straightness thereof is greatly improved. That is, the convex piece of the suspension vehicle that fits loosely in the narrow guide groove suppresses the swing of the suspension vehicle, and the moving wall does not move at each intersection without the suspension bolt hitting the corner of the guide groove and moving. Becomes smooth.
