Description

この発明は有軌道台車システムに関し、特に位置決め用の被検出体の配置に関する。   The present invention relates to a tracked bogie system, and more particularly to the arrangement of an object to be detected for positioning.

スタッカークレーンその他の有軌道台車では、走行レールと平行に位置決め用のドグレールを設け、ドグレール内に位置決め用の被検出体として、ドグを配置することが知られている（特許文献１）。このようなドグレールを図５に示すと、６０は走行レール、６２はドグレールで、例えばラックに沿って走行レール６０に平行に配置されている。６３は櫛歯などのマークを用いたドグ、６５は給電板で、非接触給電やブラシによる給電などで、有軌道台車に電力を供給する。   In stacker cranes and other tracked carriages, it is known that a dog for positioning is provided in parallel with the traveling rail, and a dog is arranged as a detected body for positioning in the dog rail (Patent Document 1). FIG. 5 shows such a dogleil. Reference numeral 60 denotes a travel rail, and reference numeral 62 denotes a dogleil, which are arranged in parallel to the travel rail 60 along a rack, for example. 63 is a dog using marks such as comb teeth, and 65 is a power feeding plate, which supplies power to the tracked carriage by non-contact power feeding or power feeding by a brush.

図５のドグ配置では、メンテナンス時などに有軌道台車の走行経路を人が通行すると、ドグ６３がむき出しのため、人の足で踏まれて損傷することがある。即ち走行レール６０の両側にラックがあり、その間のスペースは広くはない。また走行レール６０は歩行の障害となるので、これを避けるように歩くと、ドグ６３を足で踏みやすい。ドグ６３が損傷すると、スタッカークレーンなどの有軌道台車は停止位置の位置決めができず、走行不能になる。ここでドグ６３を肉厚にして強度を増すと損傷を避けることはできるが、ドグ６３の加工が難しくなり、櫛歯のピッチを小さくし難くなる。
特開平７−２４２１３９号 In the dog arrangement of FIG. 5, when a person passes along the travel route of the tracked carriage during maintenance or the like, the dog 63 may be exposed and damaged by being stepped on by a person. That is, there are racks on both sides of the running rail 60, and the space between them is not wide. Moreover, since the running rail 60 becomes an obstacle to walking, if the user walks to avoid this, it is easy to step on the dog 63. When the dog 63 is damaged, the tracked carriage such as a stacker crane cannot be positioned at the stop position and cannot travel. If the thickness of the dog 63 is increased to increase the strength, damage can be avoided, but the processing of the dog 63 becomes difficult, and it becomes difficult to reduce the pitch of the comb teeth.

この発明の課題は、有軌道台車の位置決め用の被検出体が、人の足で踏まれて損傷することを防止することにある。
請求項２の発明での追加の課題は、被検出体の設置を容易にすることにある。
請求項３の発明での追加の課題は、被検出体の設置に伴う、レール幅の増加を最小限にすることにある。 An object of the present invention is to prevent a detected object for positioning a tracked carriage from being damaged by being stepped on by a person's foot.
An additional problem in the invention of claim 2 is to facilitate installation of the detection object.
An additional problem in the invention of claim 3 is to minimize the increase in rail width accompanying the installation of the detected object.

この発明は、有軌道台車の走行車輪を走行レールの走行面で支持するようにした有軌道台車システムであって、
前記走行レールは、走行面の下部の左右にくぼみを備え、
前記くぼみ内で走行レールに被検出体を取り付けて、該被検出体が平面視で前記走行面により覆われ、走行面の外側に露出しないようにすると共に、
前記有軌道台車に前記被検出体を検出するためのセンサを設けた、ことを特徴とする。 This invention is a tracked carriage system that supports the running wheels of the tracked carriage on the running surface of the running rail,
The running rail has indentations on the left and right of the lower part of the running surface,
A detected object is attached to the traveling rail in the recess so that the detected object is covered by the traveling surface in a plan view and is not exposed to the outside of the traveling surface.
The tracked carriage is provided with a sensor for detecting the detected object.

好ましくは、前記くぼみ内で、走行レールにその長尺方向に平行な溝を設けて、該溝を利用して前記被検出体を走行レールに固定する。   Preferably, a groove parallel to the longitudinal direction is provided in the traveling rail in the recess, and the detected body is fixed to the traveling rail using the groove.

また好ましくは、前記有軌道台車の走行車輪の左右にガイドローラを設けると共に、走行レールの走行面の左右に鉛直なガイド面を設けて、該左右のガイド面で前記左右のガイドローラをガイドする。   Preferably, guide rollers are provided on the left and right of the traveling wheels of the tracked carriage, and vertical guide surfaces are provided on the left and right of the traveling surface of the traveling rail, and the left and right guide rollers guide the left and right guide rollers. .

この発明では、被検出体を走行面の下部のくぼみ内に配置して、平面視で走行面により被検出体が覆われるようにするので、メンテナンス時などに走行レールに沿って人が歩行しても、踏みつけられて損傷することがない。また被検出体は走行レールの走行面により隠されるので、丈夫な部材にする必要がない。   In this invention, since the detected object is arranged in the recess below the traveling surface so that the detected object is covered by the traveling surface in plan view, a person walks along the traveling rail during maintenance or the like. However, it will not be trampled and damaged. Further, since the detected object is hidden by the traveling surface of the traveling rail, it is not necessary to use a strong member.

走行レールの長尺方向に平行な溝を設けて、この溝を利用して被検出体を走行レールに固定すると、被検出体の取付が容易になる。さらに溝は走行レールの製造時に容易に形成することができる。   When a groove parallel to the longitudinal direction of the traveling rail is provided and the detected body is fixed to the traveling rail using this groove, the detected body is easily attached. Furthermore, the groove can be easily formed when the traveling rail is manufactured.

有軌道台車の走行車輪の左右にガイドローラを設けると共に、走行レールの走行面の左右にガイド面を設けてガイドすると、ガイドローラ間に間隔が必要なため、走行面も幅広になり、これに伴って被検出体を配置するだけのスペースを容易に得ることができる。従って、走行レールのくぼみ内に被検出体を設けることに伴う、走行レール幅の増加を最小限にできる。   When guide rollers are provided on the left and right sides of the running wheels of the tracked carriage, and guide surfaces are provided on the left and right sides of the running surface of the running rail, the distance between the guide rollers is required, so the running surface becomes wider. Accordingly, it is possible to easily obtain a space for arranging the detection object. Accordingly, an increase in the width of the traveling rail accompanying the provision of the detected object in the recess of the traveling rail can be minimized.

以下に本発明を実施するための最適実施例を示す。   In the following, an optimum embodiment for carrying out the present invention will be shown.

図１〜図４に、スタッカークレーンを例に実施例を示す。なおスタッカークレーンの走行レール２の両側に図示しないラックがあり、ラック間のスペースをスタッカークレーンの走行スペースとするものとする。各図において、２は走行レールで、鉛直方向断面形状はＩ字状もしくはＴ字状であり、走行レール２の上面は水平な走行面４で、その左右両側に鉛直なガイド面５，６がある。走行レール２の下部には、水平な取付部８があり、ガイド面５，６と取付部８の間は左右のくぼみ１０，１０となっている。くぼみ１０内で走行レール２に左右の取付溝１２，１３を設け、取付部８の上部で走行レール２に左右一対の取付溝１４，１５を設ける。走行レール２は鋼材の押し出しや引き抜きにより形成され、その形状は走行レール２の長尺方向位置が変化しても一定で、くぼみ１０や取付溝１２〜１５の形状も長尺方向位置が変化しても一定である。   1 to 4 show an embodiment of a stacker crane as an example. Note that there are racks (not shown) on both sides of the travel rail 2 of the stacker crane, and the space between the racks is used as the travel space of the stacker crane. In each figure, 2 is a traveling rail, and the vertical cross-sectional shape is I-shaped or T-shaped. The upper surface of the traveling rail 2 is a horizontal traveling surface 4, and vertical guide surfaces 5, 6 are provided on the left and right sides thereof. is there. At the lower part of the traveling rail 2, there is a horizontal mounting portion 8, and the left and right recesses 10 are formed between the guide surfaces 5 and 6 and the mounting portion 8. Left and right mounting grooves 12 and 13 are provided in the traveling rail 2 within the recess 10, and a pair of left and right mounting grooves 14 and 15 are provided in the traveling rail 2 above the mounting portion 8. The traveling rail 2 is formed by extruding or pulling out a steel material, and its shape is constant even if the longitudinal direction position of the traveling rail 2 changes, and the shape of the recess 10 and the mounting grooves 12 to 15 also changes in the longitudinal direction. It is constant.

１６は取付プレートで、ボルト１８等により床面２０に走行レール２を取り付ける。位置決めドグ２２は長尺状で、走行レール２の長尺方向（走行方向）のほぼ全長に渡って取り付け、減速ドグ２４はスタッカークレーンを減速させてオーバーランさせたないためのドグで、例えば走行レール２の走行方向の両端付近に設ける。位置決めドグ２２や減速ドグ２４は断面Ｌ字状の形状の部材で、Ｌ字の１辺をボルト２６とナット２７で取付溝１２，１３に取り付ける。なおナット２７は取付溝１２，１３内に収容したインサートナットである。ドグ２２，２４のＬ字の他辺を所定のピッチで切り欠いて、櫛歯２８，２９とする。   Reference numeral 16 denotes an attachment plate, which attaches the traveling rail 2 to the floor surface 20 with bolts 18 or the like. The positioning dog 22 is long and is attached over almost the entire length of the traveling rail 2 in the longitudinal direction (traveling direction), and the deceleration dog 24 is a dog for decelerating the stacker crane so as not to overrun, for example, traveling Provided near both ends of the rail 2 in the traveling direction. The positioning dog 22 and the speed reduction dog 24 are members having an L-shaped cross section, and one side of the L shape is attached to the mounting grooves 12 and 13 with bolts 26 and nuts 27. The nut 27 is an insert nut accommodated in the mounting grooves 12 and 13. The other sides of the L-shape of the dogs 22 and 24 are cut out at a predetermined pitch to form comb teeth 28 and 29.

３０は原点ドグ、３２はオーバーランドグで、断面形状はＬ字状で、原点ドグ３０は走行レール２の原点付近に設けて原点位置を示し、オーバーランドグ３２は走行レール２の走行方向両端に設けて、スタッカークレーンのオーバーランを防止する。原点ドグ３０は取付溝１４に、オーバーランドグ３２は取付溝１５に、それぞれボルト３４とインサートナットなどのナット３５で固定する。   Reference numeral 30 is an origin dog, 32 is an overland, and the cross-sectional shape is L-shaped. The origin dog 30 is provided near the origin of the traveling rail 2 to indicate the origin position, and the overland 32 is provided at both ends of the traveling rail 2 in the traveling direction. Prevent overrun of the stacker crane. The origin dog 30 is fixed to the mounting groove 14 and the overland 32 is fixed to the mounting groove 15 with bolts 34 and nuts 35 such as insert nuts.

図２に、走行レール２に対するドグ２２，２４，３０，３２の配置を模式的に示す。実際には走行方向の同じ位置に４種類のドグ２２，２４，３０，３２が並べて配置されることはないが、図２ではこれらの左右方向位置（平面視で走行方向に直角な方向での位置）を示すため並べて配置する。ドグ２２，２４は平面視で走行面４により覆われ、図４に示すようにくぼみ１０内に配置されて、人が足を踏み下ろしても走行面４やガイド面５，６などのために、足が接触しない位置にある。位置決めドグ２２は走行レール２の長尺方向のほぼ全長に渡って設けられ、１箇所でも損傷するとスタッカークレーンの走行が不能になるため、くぼみ１０内に配置して踏まれないようにする。減速ドグ２４は走行レール２の走行方向両端にしかない部材なので、保護の必要性は位置決めドグ２２よりも低いが、走行面４の下側に左右一対のくぼみ１０，１０が存在するので、その一方を利用して配置する。これらのため、位置決めドグ２２や減速ドグ２４を肉薄にし、櫛歯２８，２９を切り欠くピッチを小さくできるため、高精度な位置決めができる。原点ドグ３０やオーバーランドグ３２は走行レール２の端部にのみ存在する部材で、例えば肉厚の丈夫な部材としてくぼみ１０の外側に配置する。   FIG. 2 schematically shows the arrangement of the dogs 22, 24, 30 and 32 with respect to the traveling rail 2. Actually, the four types of dogs 22, 24, 30, 32 are not arranged side by side at the same position in the traveling direction, but in FIG. 2, these left and right positions (in a direction perpendicular to the traveling direction in plan view) Position). The dogs 22 and 24 are covered with the running surface 4 in a plan view, and are disposed in the recess 10 as shown in FIG. 4, so that even if a person steps down, the dogs 22 and 24 are used for the running surface 4 and the guide surfaces 5 and 6. , The position where the foot does not touch. The positioning dog 22 is provided over substantially the entire length of the traveling rail 2 in the longitudinal direction, and if it is damaged even at one place, the traveling of the stacker crane becomes impossible. Therefore, the positioning dog 22 is arranged in the recess 10 so as not to be stepped on. Since the deceleration dog 24 is a member only at both ends of the traveling rail 2 in the traveling direction, the necessity for protection is lower than that of the positioning dog 22, but there is a pair of left and right depressions 10, 10 below the traveling surface 4. Place using. For this reason, the positioning dog 22 and the speed reduction dog 24 can be made thin and the pitch at which the comb teeth 28 and 29 are cut out can be reduced, so that highly accurate positioning can be performed. The origin dog 30 and the overland 32 are members that exist only at the end of the traveling rail 2, and are disposed outside the indentation 10 as, for example, thick and strong members.

図３に、走行レール２とスタッカークレーン３８の走行車輪４０等の関係を示す。４２，４３は左右のガイドローラで、ガイド面５，６によりガイドされ、ガイドローラ４２，４３間にある程度の間隔が必要なため、走行面４は必然的に幅が広くなり、この結果大きなくぼみ１０を得ることができる。４５は走行モータ、４６はブレーキで、その配置は任意である。   FIG. 3 shows the relationship between the traveling rail 2 and the traveling wheels 40 of the stacker crane 38. Reference numerals 42 and 43 are left and right guide rollers, which are guided by the guide surfaces 5 and 6 and require a certain distance between the guide rollers 42 and 43, so that the running surface 4 is necessarily widened, resulting in a large depression. 10 can be obtained. 45 is a traveling motor, 46 is a brake, and the arrangement thereof is arbitrary.

４８はスタッカークレーン３８側に設けたブラケットで、ガイドローラ４２，４３の走行方向前後の位置でスタッカークレーン本体に取り付けられている。５０は位置決めセンサで、５１は減速センサ、５２は原点センサ、５３はオーバーランセンサで、ここではセンサ５０〜５３はいずれも光電センサとし、櫛歯の櫛による透過光のオン／オフを利用して、櫛歯をカウントする。なおセンサの種類は任意で、ドグ２２，２４，３０，３２には櫛歯以外に、所定のピッチで色彩が変化するカラーテープや磁気マークなどを用い、センサ５０〜５３には光電センサの他に他の光学センサや磁気センサなどを用いてもよい。   A bracket 48 is provided on the stacker crane 38 side, and is attached to the stacker crane main body at positions before and after the guide rollers 42 and 43 in the traveling direction. 50 is a positioning sensor, 51 is a deceleration sensor, 52 is an origin sensor, and 53 is an overrun sensor. Here, each of the sensors 50 to 53 is a photoelectric sensor and uses on / off of transmitted light by a comb-like comb. Count the comb teeth. The type of sensor is arbitrary, and the dogs 22, 24, 30, and 32 use color tapes or magnetic marks that change in color at a predetermined pitch in addition to comb teeth, and the sensors 50 to 53 include photoelectric sensors. In addition, other optical sensors or magnetic sensors may be used.

実施例の動作を示す。スタッカークレーン３８はその原点位置を認識するため、原点ドグ３０を用い、オーバーランを防止するためオーバーランドグ３２と減速ドグ２４とを用いる。そして各ステーションやラックの棚との間での物品の移載のため、位置決めドグ２２の櫛歯をカウントして現在位置を認識し、走行制御を行う。   The operation of the embodiment will be described. The stacker crane 38 uses the origin dog 30 to recognize the origin position, and uses the overland 32 and the speed reduction dog 24 to prevent overrun. Then, in order to transfer articles between stations and rack shelves, the comb teeth of the positioning dog 22 are counted to recognize the current position, and travel control is performed.

ここで走行レール２とラックの間にはスタッカークレーンの車体幅分の隙間があり、スタッカークレーンやラックのメンテナンスが必要な場合、人が走行レール２に沿って歩行する。狭いスペースを歩行するので、図５の従来例の場合、ドグ６３を踏みつけて破損することがある。これに対して実施例では、位置決めドグ２２と減速ドグ２４が走行面４の下部に隠され、踏み下ろした足と接触して損傷することがない。このためメンテナンス時の位置決めドグ２２の損傷を防止できる。またドグ２２，２４を肉薄にして、精細な櫛歯を設けることができる。ドグ２２，２４，３０，３２の取付は、取付溝１２〜１５とボルト２６，３４、ナット２７，３５で簡単に行うことができる。例えば図４の上部の円内に拡大して示すように、溝１２等の入口幅をｗ１、奧側の幅をｗ２とする。次にナット２７等として平面形状が長方形ないしは楕円形のものを用い、ナット２７等の長辺が入口幅ｗ１超で奧側の幅ｗ２未満、短辺が入口幅ｗ１未満としておく。するとナット２７等の長辺を溝１２等の長手方向に平行にすると、走行レール２の中間位置でもナット２７等を溝１２等の内部に挿入でき、次いでナット２７等を例えば９０°回動させてドグ２２等を固定すると良い。なおこの点は溝１３〜１５やナット３５についても同様である。そして取付溝１２〜１５は走行レール２の押し出し時や引き抜き時に簡単に形成できる。さらに図５のドグ６３のようなむき出しのドグがないので、メンテナンス時の歩行が容易になる。   Here, there is a gap corresponding to the vehicle width of the stacker crane between the traveling rail 2 and the rack. When maintenance of the stacker crane or the rack is necessary, a person walks along the traveling rail 2. Since it walks in a narrow space, in the case of the conventional example in FIG. On the other hand, in the embodiment, the positioning dog 22 and the deceleration dog 24 are concealed in the lower part of the running surface 4 and do not come into contact with the stepped-down foot and are damaged. For this reason, damage to the positioning dog 22 during maintenance can be prevented. Further, the dogs 22 and 24 can be made thin to provide fine comb teeth. The dogs 22, 24, 30, and 32 can be easily attached with the mounting grooves 12 to 15, the bolts 26 and 34, and the nuts 27 and 35. For example, as shown in the enlarged circle in the upper part of FIG. Next, the nut 27 or the like having a rectangular or elliptical plan shape is used, and the long side of the nut 27 or the like is greater than the entrance width w1 and less than the heel side width w2, and the short side is less than the entrance width w1. Then, when the long sides of the nut 27 and the like are made parallel to the longitudinal direction of the groove 12 and the like, the nut 27 and the like can be inserted into the groove 12 and the like even at an intermediate position of the traveling rail 2, and then the nut 27 and the like are rotated by 90 °, for example. The dog 22 or the like may be fixed. This also applies to the grooves 13 to 15 and the nut 35. The mounting grooves 12 to 15 can be easily formed when the traveling rail 2 is pushed out or pulled out. Further, since there is no exposed dog like the dog 63 in FIG. 5, walking during maintenance becomes easy.

実施例ではスタッカークレーンを用いたシステムを説明したが、地上走行の他の有軌道台車の場合も全く同様に実施できる。
In the embodiment, a system using a stacker crane has been described. However, the present invention can be implemented in the same manner in the case of other tracked carriages that are traveling on the ground.
