Description

本発明は、例えば、自動車用エンジン等のワークを、向きを変えつつ搬送するために用いられる搬送装置に関する。   The present invention relates to a transport device used for transporting a workpiece such as an automobile engine while changing its orientation.

従来より、自動車用エンジン等のワークの搬送に、ワークを保持した状態で軸まわりに回転可能である方向転換機と、この方向転換機を移動させる推進部（シリンダ・モータ等）とを備えたトラバーサ搬送装置が用いられている。   Conventionally, in order to transport a workpiece such as an automobile engine, a direction changing machine that can rotate around an axis while holding the workpiece and a propulsion unit (cylinder, motor, etc.) that moves the direction changing machine are provided. A traverser transport device is used.

そして、方向転換機を回転させるには、方向転換機の移動方向にラックを配置すると共に、方向転換機に前記ラックと噛み合うピニオンを設ける構成を採用することが考えられる。すなわち、前記ラックと噛み合うピニオンを有する方向転換機は、移動すると自動的に回転もすることになる。   And in order to rotate a direction change machine, while arranging a rack in the moving direction of a direction change machine, it is possible to employ | adopt the structure which provides the pinion which meshes with the said rack in a direction change machine. That is, the direction changing machine having the pinion that meshes with the rack automatically rotates when it moves.

しかし、上記搬送装置では、前記ラックとピニオンの歯車ピッチに起因して、方向転換機の停止時の向きあるいは位置がずれるおそれがある。また、方向転換機により搬送されるワークが方向転換機の停止時に所望の向きに向くようにするためには、方向転換機の移動距離や前記ラックの配置等を適切に調整する必要があるが、そのような調整を行うには労力や時間が非常にかかるという問題もある。そして、これらのことは、前記方向転換機を回転させるために、上述のラックとピニオンを組み合わせる構成に代えて、チェーンとスプロケットを組み合わせる構成を採用した場合でも同様である。   However, in the said conveying apparatus, there exists a possibility that the direction or position at the time of a stop of a direction change machine may shift | deviate due to the gear pitch of the said rack and pinion. Moreover, in order to make the work conveyed by the direction changer turn in the desired direction when the direction changer stops, it is necessary to appropriately adjust the moving distance of the direction changer, the arrangement of the racks, and the like. There is also a problem that it takes a lot of labor and time to make such an adjustment. And these things are the same also when adopting the structure which replaces with the structure which combines the above-mentioned rack and pinion in order to rotate the said direction change machine, and combines a chain and a sprocket.

本発明は上述の実情に鑑みてなされたもので、その目的は、ワークの搬送に際して、ワークを回転させて所定の向きに向かせた状態で所定の位置に停止させることができ、さらに、ワークを所定の向きに向かせるための調整が容易である搬送装置を提供することにある。   The present invention has been made in view of the above-described circumstances, and an object of the present invention is to stop a workpiece at a predetermined position in a state where the workpiece is rotated and oriented in a predetermined direction when the workpiece is transported.

また、前記搬送装置において、前記方向転換機が、ワークを保持する保持部と、この保持部に軸体を介して固定される回転ドラムとを有し、この回転ドラムに前記変換部材が巻かれていてもよい（請求項２）。   Further, in the transport apparatus, the direction changing machine includes a holding unit that holds a workpiece, and a rotating drum that is fixed to the holding unit via a shaft, and the conversion member is wound around the rotating drum. (Claim 2).

具体的には、前記搬送装置において、前記回転ドラムにおいて変換部材が巻かれる部分の直径が変更可能となるように構成されていてもよい（請求項３）。   Specifically, the conveying device may be configured such that a diameter of a portion around which the conversion member is wound in the rotating drum can be changed (Claim 3).

請求項１に係る発明では、ストッパによって方向転換機の軸まわりの回転角度を規制することができるので、ワークの搬送に際して、ワークを回転させて所定の向きに向かせた状態で所定の位置に停止させることができ、さらに、ワークを所定の向きに向かせるための調整が容易である搬送装置が得られる。   In the invention according to claim 1, since the rotation angle around the axis of the direction changer can be regulated by the stopper, when the workpiece is transported, the workpiece is rotated and directed to a predetermined position in a predetermined direction. Further, it is possible to obtain a transport device that can be stopped and that can be easily adjusted to direct the workpiece in a predetermined direction.

請求項２に係る発明では、シンプルな構造で上記の効果を奏する搬送装置が得られる。さらに、請求項３に係る発明では、上記の効果に加えて、方向転換機の角度変更を簡単に行えるという効果を奏する搬送装置が得られる。   In the invention according to claim 2, a transport device having the above effects can be obtained with a simple structure. Furthermore, in the invention according to claim 3, in addition to the above-described effect, there can be obtained a transport device that has an effect that the angle of the direction changing machine can be easily changed.

図１は、本発明の一実施の形態に係る搬送装置の構成を概略的に示す説明図である。この実施形態に係る搬送装置は、例えば自動車用エンジン等のワークを搬送し、その搬送中にワークが方向転換（回転）するように構成されたものである。そして、ワークを回転させるために、前記搬送装置は、ワークを保持した状態で上下方向の軸まわりに回転可能である方向転換機１（図１参照）を備えている。   FIG. 1 is an explanatory view schematically showing a configuration of a transport apparatus according to an embodiment of the present invention. The transport apparatus according to this embodiment is configured to transport a work such as an automobile engine, for example, and the work is turned (rotated) during the transport. And in order to rotate a workpiece | work, the said conveying apparatus is provided with the direction change machine 1 (refer FIG. 1) which can be rotated to the surroundings of an up-down direction axis | shaft in the state holding the workpiece | work.

すなわち、前記方向転換機１は、図１に示すように、ワークを保持するほぼ直方体形状の保持部２と、この保持部２のほぼ中央から垂下する軸体３と、前記保持部２に軸体３を介して固定される回転ドラム４とを有し、保持部２、軸体３および回転ドラム４は一体的に回転するように構成されている。   That is, as shown in FIG. 1, the direction changing machine 1 includes a substantially rectangular parallelepiped-shaped holding portion 2 that holds a workpiece, a shaft body 3 that hangs down from the substantially center of the holding portion 2, and a shaft that is The holding part 2, the shaft body 3, and the rotating drum 4 are configured to rotate integrally.

また、前記保持部２に載置（保持）されたワークを搬送するために、前記搬送装置は、ワークを方向転換機１ごと移動させる推進部５を備え、この推進部５は、台車によって構成されている。具体的に説明すると、推進部５は、前記保持部２の下方に配置され平面視ほぼ円形状の台車本体６と、この台車本体６の下部に設けられた複数（例えば四つ）の車輪７と、これら車輪７のうち少なくとも一つの車輪を駆動回転させる例えばモータ等の駆動源（図示していない）とを備えている。そして、台車本体６において前記軸体３に挿通される部分には、軸体３をその軸まわりの回転が可能な状態で保持するベアリング部８が設けられており、台車本体６が方向転換機１と共回りしないように構成されている。   Moreover, in order to convey the workpiece placed (held) on the holding unit 2, the conveying device includes a propulsion unit 5 that moves the workpiece together with the direction changer 1, and the propulsion unit 5 is constituted by a carriage. Has been. More specifically, the propulsion unit 5 includes a cart body 6 that is disposed below the holding unit 2 and has a substantially circular shape in plan view, and a plurality of (for example, four) wheels 7 that are provided at the bottom of the cart body 6. And a drive source (not shown) such as a motor for driving and rotating at least one of the wheels 7. And the bearing part 8 which hold | maintains the shaft body 3 in the state which can be rotated to the periphery of the axis | shaft 3 is provided in the part penetrated by the said shaft body 3 in the trolley | bogie main body 6, and the trolley | bogie main body 6 is a direction change machine. 1 is configured so as not to rotate together.

さらに、前記方向転換機１を回転させるために、前記搬送装置は、前記方向転換機１の移動経路に沿って張設され移動中の方向転換機１に接触して方向転換機１の推進力の一部を方向転換機１の軸まわりの回転力に変換するほぼ線状またはロープ状または帯状の変換部材９を備えている。この実施の形態の変換部材９はワイヤーにより構成されている。そして、変換部材９は、前記回転ドラム４に一重に巻かれた状態で、前記推進部５を構成する台車が走行する走行台１０の下方に張設されている。   Further, in order to rotate the direction changing machine 1, the conveying device is stretched along the movement path of the direction changing machine 1 and comes into contact with the moving direction changing machine 1 so that the propulsive force of the direction changing machine 1 Is provided with a substantially linear, rope-like or belt-like conversion member 9 for converting a part of the rotation into a rotational force around the axis of the direction changer 1. The conversion member 9 of this embodiment is composed of a wire. The conversion member 9 is stretched under the traveling base 10 on which the carriage constituting the propulsion unit 5 travels while being wound around the rotating drum 4 in a single layer.

なお、前記走行台１０には、前記方向変換機１の軸体３を挿通させるための溝（図示していない）が方向変換機１の移動経路に沿って設けられている。ここで、推進部５は、図１に示す走行台１０の左端（始点）から右端（終点）までの間を往復走行するのであり、この実施の形態では、以下、符号Ａで示す方向に走行することを前進、符号Ｂで示す方向にすることを後退という。   The traveling platform 10 is provided with a groove (not shown) through which the shaft 3 of the direction changer 1 is inserted along the movement path of the direction changer 1. Here, the propulsion unit 5 reciprocates from the left end (start point) to the right end (end point) of the traveling platform 10 shown in FIG. 1. In this embodiment, the propulsion unit 5 travels in the direction indicated by reference sign A below. This is called forward, and the direction indicated by B is called backward.

また、図２（Ａ）および（Ｂ）は、始点および終点に位置するときの前記搬送装置の構成を概略的に示す平面図であり、図１および図２に示すように、搬送装置は、前記方向転換機１の軸まわりの回転角度を規制する二つのストッパ１１，１２を備えている。これらのストッパ１１，１２は、上下方向の軸まわりに回転する保持部２の側面に当接して保持部２の回転を方向転換機１ごと停止させるように構成されており、前記台車本体６の上面の適宜の位置に設けられている。そして、これに対して、前記保持部２の左右側面における前記ストッパ１１，１２が当接する位置に、ストッパ１１，１２が当接しても傷がつかないあるいは傷がつきにくい材料からなるストッパ受け部１３が設けられている。なお、図２（Ａ）および（Ｂ）において、Ｘは保持部２の回転軸である。   2 (A) and 2 (B) are plan views schematically showing the configuration of the transport device when positioned at the start point and the end point. As shown in FIGS. 1 and 2, the transport device Two stoppers 11 and 12 for restricting the rotation angle around the axis of the direction changing machine 1 are provided. These stoppers 11 and 12 are configured to contact the side surface of the holding unit 2 that rotates about the vertical axis and stop the rotation of the holding unit 2 together with the direction changer 1. It is provided at an appropriate position on the upper surface. On the other hand, a stopper receiving portion made of a material that is not scratched or hardly scratched even when the stoppers 11, 12 come into contact with the stoppers 11, 12 on the left and right side surfaces of the holding portion 2. 13 is provided. 2A and 2B, X is the rotation axis of the holding unit 2.

次に、上記の構成からなる搬送装置の作動について説明する。なお、図３および図４は、前進時および後退時の搬送装置に保持されたワークＷの状態を概略的に示す平面図であり、図３および図４において、方向転換機１および推進部５はワークＷに隠れて見えておらず、また、軸体３を挿通させるために走行台１０に設けられている前記溝の図示は省略してある。まず、図３（Ａ）に示すように、始点にある搬送装置の保持部２にワークＷが載置（保持）される。そして、この状態から、前記推進部５の走行により搬送装置が前進すると、方向転換機１の回転ドラム４に変換部材９が巻かれているため、方向転換機１の推進力の一部が方向転換機１の軸まわりの回転力に変換され、方向転換機１は軸まわりに回転することになる。   Next, the operation of the transport apparatus having the above configuration will be described. 3 and 4 are plan views schematically showing the state of the workpiece W held by the transport device during forward movement and backward movement. In FIGS. 3 and 4, the direction changer 1 and the propulsion unit 5 are shown. Is not visible behind the workpiece W, and the grooves provided in the carriage 10 for inserting the shaft body 3 are not shown. First, as shown in FIG. 3A, the workpiece W is placed (held) on the holding unit 2 of the transfer device at the starting point. From this state, when the transport device advances by traveling of the propulsion unit 5, the conversion member 9 is wound around the rotating drum 4 of the direction changer 1. It is converted into a rotational force around the axis of the changer 1, and the direction changer 1 rotates around the axis.

その後、搬送装置により搬送されるワークＷは、図３（Ｂ）に示す状態を経て、図３（Ｃ）に示すように、搬送装置が始点にあったときの状態から平面視において約９０°だけ反時計まわり（左まわり）に回転した状態となる。すなわち、ワークＷは、図３（Ａ）に示すように、始点にある搬送装置の保持部２に載置された状態では、その前部Ｆが図中下側、後部Ｒが図中上側に位置する場合、図３（Ｃ）に示す状態では、前部Ｆは図中右側、後部Ｒは図中左側に位置することとなる。そして、このとき、図２（Ｂ）に示すように、保持部２のストッパ受け部１３にストッパ１２が当接し、保持部２を有する方向転換機１の回転が停止する。従って、この後は、方向転換機１の回転ドラム４と変換部材９とはスリップし、方向転換機１は回転せずに終点まで前進するのであり、ワークＷは最終的に図３（Ｄ）に示す状態となる。なお、図３（Ｄ）において、Ｓは方向転換機１が回転せずにスリップ移動した区間を示している。   Thereafter, the workpiece W transported by the transport device passes through the state shown in FIG. 3 (B) and, as shown in FIG. 3 (C), about 90 ° in plan view from the state when the transport device is at the starting point. Only counterclockwise (left-handed). That is, as shown in FIG. 3A, when the workpiece W is placed on the holding unit 2 of the transfer device at the starting point, the front portion F is on the lower side in the drawing and the rear portion R is on the upper side in the drawing. In the state shown in FIG. 3C, the front portion F is located on the right side in the drawing, and the rear portion R is located on the left side in the drawing. At this time, as shown in FIG. 2B, the stopper 12 comes into contact with the stopper receiving portion 13 of the holding portion 2, and the rotation of the direction change machine 1 having the holding portion 2 stops. Accordingly, after this, the rotating drum 4 and the conversion member 9 of the direction changing machine 1 slip, and the direction changing machine 1 advances to the end point without rotating, and the workpiece W is finally moved to FIG. It will be in the state shown in In addition, in FIG.3 (D), S has shown the area where the direction change machine 1 slipped without rotating.

また、終点にある搬送装置の保持部２にワークＷを載置して、搬送装置を始点へと後退させてもよい。この場合、具体的には、図４（Ａ）に示すように、終点にある搬送装置の保持部２にワークＷが載置（保持）される。そして、この状態から、前記推進部５の走行により搬送装置は後退し、この後退とともに方向転換機１は軸まわりに回転することになる。   Alternatively, the workpiece W may be placed on the holding unit 2 of the transfer device at the end point, and the transfer device may be retracted to the start point. In this case, specifically, as shown in FIG. 4A, the workpiece W is placed (held) on the holding unit 2 of the transfer device at the end point. Then, from this state, the conveying device is moved backward by the traveling of the propulsion unit 5, and the direction changer 1 rotates around the axis along with the backward movement.

その後、搬送装置により搬送されるワークＷは、図４（Ｂ）に示す状態を経て、図４（Ｃ）に示すように、搬送装置が終点にあったときの状態から平面視において約９０°だけ時計まわり（右まわり）に回転した状態となる。すなわち、ワークＷは、図４（Ａ）に示すように、終点にある搬送装置の保持部２に載置された状態では、その前部Ｆが図中右側、後部Ｒが図中左側に位置する場合、図４（Ｃ）に示す状態では、前部Ｆは図中下側、後部Ｒは図中上側に位置することとなる。そして、このとき、図２（Ａ）に示すように、保持部２のストッパ受け部１３にストッパ１１が当接し、保持部２を有する方向転換機１の回転が停止する。従って、この後は、方向転換機１の回転ドラム４と変換部材９とはスリップし、方向転換機１は回転せずに始点まで前進するのであり、ワークＷは最終的に図４（Ｄ）に示す状態となる。なお、図４（Ｄ）において、Ｔは方向転換機１が回転せずにスリップ移動した区間を示し、この実施の形態では、区間Ｓと区間Ｔとはほぼ同じ距離である。   Thereafter, the workpiece W transported by the transport device passes through the state shown in FIG. 4B, and as shown in FIG. 4C, it is about 90 ° in plan view from the state when the transport device is at the end point. It will be in the state rotated only clockwise (clockwise). That is, as shown in FIG. 4A, when the work W is placed on the holding unit 2 of the transfer device at the end point, the front F is positioned on the right side in the drawing and the rear R is positioned on the left side in the drawing. In this case, in the state shown in FIG. 4C, the front part F is located on the lower side in the figure and the rear part R is located on the upper side in the figure. At this time, as shown in FIG. 2A, the stopper 11 comes into contact with the stopper receiving portion 13 of the holding portion 2, and the rotation of the direction changing machine 1 having the holding portion 2 is stopped. Therefore, after this, the rotating drum 4 and the conversion member 9 of the direction changing machine 1 slip, and the direction changing machine 1 advances to the starting point without rotating, and the workpiece W is finally moved to FIG. 4 (D). It will be in the state shown in In FIG. 4D, T indicates a section in which the direction changer 1 slips without rotating. In this embodiment, the section S and the section T are substantially the same distance.

上記の構成からなる搬送装置では、ワークＷの向きを任意の角度（この実施の形態では９０°）だけ変えて搬送することができる。そして、始点と終点との間を往復する方向転換機１は、始点、終点に到着するまでに所定の角度の回転を終え、その後はスリップ移動するのであり、このようにいわゆる遊びを設けてあることから、搬送装置自体はシンプルな構造でありながら、方向転換機１に上記所定角度の回転を確実に行わせることができる。   In the transport apparatus having the above-described configuration, the work W can be transported while being changed by an arbitrary angle (90 ° in this embodiment). And the direction change machine 1 which reciprocates between the start point and the end point finishes rotation of a predetermined angle by the time it reaches the start point and the end point, and then slips and moves, so-called play is provided in this way. For this reason, the direction changing device 1 can reliably rotate the predetermined angle while the transport device itself has a simple structure.

また、従来の搬送装置では、方向転換機の回転角度の調整に非常に時間がかかっていたが、この実施の形態の搬送装置では、前記ストッパ１１，１２の位置によって方向転換機１の回転角度が決定されるため、回転ドラム４に変換部材９を巻き付ける際等に微調整が不要であることから、短時間で簡単に組み立てることができる。   Further, in the conventional transfer device, it takes a very long time to adjust the rotation angle of the direction changer. In the transfer device of this embodiment, the rotation angle of the direction changer 1 depends on the positions of the stoppers 11 and 12. Therefore, fine adjustment is not required when the conversion member 9 is wound around the rotary drum 4, and therefore, it can be easily assembled in a short time.

なお、本発明は上記実施の形態に限られず、種々に変形して実施することができる。例えば、保持部２は直方体形状に限られず、ワークを保持（載置）しやすい適宜の形状をしていればよい。   The present invention is not limited to the above embodiment, and can be implemented with various modifications. For example, the holding unit 2 is not limited to a rectangular parallelepiped shape, and may have an appropriate shape that can easily hold (place) the workpiece.

また、推進部５は、車輪によって自動走行する台車に限られず、例えば、牽引等によって走行する台車でもよく、また、レールに沿って移動するように構成されていてもよい。その他、ロープに吊り下げられた状態で移動するいわゆるロープウエー構造や、いわゆるケーブルカー構造のものなどであってもよい。   Further, the propulsion unit 5 is not limited to a cart that automatically travels by wheels, and may be a cart that travels by towing, for example, or may be configured to move along a rail. In addition, a so-called ropeway structure that moves while suspended from a rope, a so-called cable car structure, or the like may be used.

さらに、前記回転ドラム４において変換部材９が巻かれる部分の直径が変更可能となるように構成されていてもよく、この場合には、回転ドラム４を有する方向転換機１の回転角度を９０°に限らず、例えば１８０°等に簡単に変更することができる。そのために、例えば、回転ドラム４に、変換部材９が巻かれる部分として径の異なる部分を複数設けてもよく、また、径の異なる回転ドラム４を複数用意し、回転ドラム４を交換可能としてもよい。   Furthermore, the diameter of the portion around which the conversion member 9 is wound in the rotating drum 4 may be changeable. In this case, the rotation angle of the direction changer 1 having the rotating drum 4 is set to 90 °. For example, the angle can be easily changed to 180 ° or the like. For this purpose, for example, the rotary drum 4 may be provided with a plurality of portions having different diameters as the portion around which the conversion member 9 is wound. Alternatively, a plurality of rotary drums 4 having different diameters may be prepared and the rotary drum 4 can be replaced. Good.

また、変換部材９は、回転ドラム４に一重に巻かれている構成に限られず、二重以上に巻かれていてもよい。反対に、変換部材９が回転ドラム４に巻かれていなくてもよく、この場合には、張設された変換部材９に回転ドラム４が接触するように構成しておけばよい。すなわち、変換部材９が回転ドラム４に巻かれているか否かに拘わらず、方向転換機１の移動に伴って回転ドラム４が回転するように変換部材９が回転ドラム４に接触していればよい。   Moreover, the conversion member 9 is not restricted to the structure wound around the rotating drum 4, and may be wound more than double. On the contrary, the conversion member 9 does not have to be wound around the rotating drum 4, and in this case, the rotating drum 4 may be configured to contact the tensioned conversion member 9. That is, regardless of whether or not the conversion member 9 is wound around the rotary drum 4, the conversion member 9 is in contact with the rotary drum 4 so that the rotary drum 4 rotates as the direction change machine 1 moves. Good.

また、前記ベアリング部８はなくてもよく、台車本体６にベアリング部８に代えて貫通孔を設けてこの貫通孔に軸体３を挿通させてあってもよい。   Further, the bearing portion 8 may not be provided, and the through hole may be provided in the cart body 6 in place of the bearing portion 8, and the shaft body 3 may be inserted into the through hole.

また、前記ストッパ１１，１２を設ける位置が変更可能であるように構成しておくことが、方向転換機１が始点および終点に到着したときの保持部２の向きを簡単に調整することができる点で望ましい。   In addition, by configuring the position where the stoppers 11 and 12 are provided to be changeable, it is possible to easily adjust the direction of the holding unit 2 when the direction changer 1 arrives at the start point and the end point. Desirable in terms.

また、例えば、方向転換機１の回転角度を９０°より大きい１８０°等とする場合、保持部２の回転が、保持部２におけるストッパ受け部１３以外の部分にストッパ１１，１２が当接することによって妨げられないように、保持部２の形状やストッパ１１，１２の配置・形状を適宜に設定しておかなければならないことはいうまでもない。   Further, for example, when the rotation angle of the direction changer 1 is set to 180 ° larger than 90 °, the stoppers 11 and 12 come into contact with portions other than the stopper receiving portion 13 in the holding portion 2 when the holding portion 2 rotates. Needless to say, the shape of the holding portion 2 and the arrangement and shape of the stoppers 11 and 12 must be set appropriately so as not to be hindered by the above.
