Description

本発明は、作業者が乗って部品組付け作業を行う連続した作業床を形成することができるコンベア装置に関するものである。   The present invention relates to a conveyor device capable of forming a continuous work floor on which an operator rides and performs a part assembling operation.

被搬送物を搭載した搬送用台車を搬送経路に沿って搬送しながら作業者が乗って部品組付け作業を行う連続した作業床(作業平面)を形成することができるコンベア装置として、搬送用台車の端部同士を互いに当接させて連続した作業床を形成する直線状の作業ラインでは、台車連結装置により前後の搬送用台車を連結した状態として後押し駆動手段により定速搬送し、作業ラインから出た搬送用台車を作業ラインの入り口まで返送するリターンラインでは、作業ラインから出た搬送用台車の連結を解除して高速駆動手段により高速で搬送するものがある(例えば、特許文献1参照。)。
また、搬送用台車(可動体)の相対向した前後部間を連結装置を介して横方向で相対回動自在に連結し、搬送用台車群(可動体群)と連結装置群とにより列車状の無端連続体を形成し、この無端連続体を送り装置により駆動するものがある(例えば、特許文献2参照。)。
さらに、搬送用台車(パレット)を、搬送方向に対して複数に分割し、各分割搬送用台車(分割パレット)を水平面内において相互に回動可能になるよう連結するとともに、搬送用台車の搬送方式を、前方を進行する搬送用台車に対して後続する搬送用台車が突き当たると、後続する搬送用台車が後押しするようなフリーフロー方式としたものがある(例えば、特許文献3参照。)。
Carriage cart as a conveyor device that can form a continuous work floor (working plane) on which an operator rides and carries parts assembling work while carrying a transport cart carrying an object to be transported along the transport path In a linear work line that forms a continuous work floor with the ends of the two abutting each other, the front and rear transport carts are connected by a cart connecting device and transported at a constant speed by a boost drive means. There is a return line that returns the transporting carriage to the entrance of the work line and disconnects the transporting carriage that has come out of the work line and transports it at high speed by high-speed driving means (see, for example, Patent Document 1). ).
In addition, the front and rear portions of the transporting carriage (movable body) facing each other are connected to each other through a connecting device so as to be relatively rotatable in the lateral direction, and the transporting carriage group (movable body group) and the connecting device group form a train shape. The endless continuous body is formed, and this endless continuous body is driven by a feeding device (see, for example, Patent Document 2).
In addition, the transport carriage (pallet) is divided into a plurality of parts in the transport direction, and the divided transport carriages (split pallets) are connected to each other so as to be rotatable in a horizontal plane. There is a system in which the system is a free flow system in which the succeeding transport cart is pushed when the succeeding transport cart hits the transport cart traveling forward (see, for example, Patent Document 3).

特許文献1のようなコンベア装置は、直線状の作業ライン以外(リターンライン)では搬送用台車の連結を解除して高速駆動手段により高速で搬送する構成であることから、直線状の作業ライン以外に作業者が乗って部品組付け作業を行う連続した作業床(作業平面)を形成することができないため、作業効率及びスペース効率が悪くなる。
また、特許文献2のようなコンベア装置は、列車状の無端連続体全体を送り装置により駆動する構成であることから、搬送用台車に対して被搬送物の積み卸しを行う際には無端連続体全体を停止させる必要があるため、作業効率が悪くなる。
さらに、特許文献3のようなコンベア装置は、前後の搬送用台車を連結せずに後続する搬送用台車により後押しするフリーフロー方式の構成であることから、前後の搬送用台車間に隙間が生じる場合があるため、作業者が乗る連続した作業床(作業平面)を確実に形成することが困難である。
Since the conveyor apparatus like patent document 1 is the structure which cancels | releases connection of the conveyance trolley | bogie and conveys at high speed by a high-speed drive means except a linear work line (return line), it is other than a linear work line Therefore, it is not possible to form a continuous work floor (work plane) on which an operator rides and performs parts assembling work, so work efficiency and space efficiency deteriorate.
Moreover, since the conveyor apparatus like patent document 2 is the structure which drives the whole train-like endless continuous body with a feeder, it is endless continuous when unloading a to-be-conveyed object with respect to the conveyance trolley | bogie. Since it is necessary to stop the whole body, work efficiency worsens.
Furthermore, since the conveyor apparatus like patent document 3 is a structure of the free flow system which backs up with the subsequent conveyance trolley | bogies, without connecting the front and rear conveyance trolleys, a clearance gap arises between the front and rear conveyance trolleys. In some cases, it is difficult to reliably form a continuous work floor (work plane) on which an operator rides.

そこで本発明が前述の状況に鑑み、解決しようとするところは、曲線状経路においても作業者が乗って部品組付け作業を行う連続した作業床(作業平面)を形成することができ、被搬送物の積み卸しを行う際に作業ラインを停止させる必要がなく、作業者が乗る連続した作業床(作業平面)を確実に形成することができるコンベア装置を提供する点にある。   Therefore, in view of the above-described situation, the present invention intends to solve the problem that a continuous work floor (work plane) on which a worker gets on a curved path and performs a part assembling work can be formed. The object of the present invention is to provide a conveyor device that can reliably form a continuous work floor (work plane) on which an operator rides without having to stop the work line when loading and unloading objects.

本発明に係るコンベア装置は、前記課題解決のために、被搬送物を搭載した搬送用台車を搬送経路に沿って搬送しながら作業者が乗って部品組付け作業を行う連続した作業床を形成することができるコンベア装置であって、前記搬送用台車の各々を、単又は複数の台車体及び前記台車体の搬送方向前側又は後側に位置して前記台車体と垂直軸まわりに相対回動可能に連結された連結台車体により構成し、前記台車体の上面及び前記連結台車体の上面を略同一水平面とし、搬送方向前後に位置する前記搬送用台車間を連結する連結手段を設け、前記搬送用台車の複数を前記連結手段により連結して搬送用台車群として曲線状経路を含む搬送経路に配置し、前記搬送用台車群を定速で搬送しながら前記台車体及び連結台車体の上面を前記作業床とて前記部品組付け作業を行う作業ラインを構成するとともに、前記搬送用台車群の搬送方向前端の前記搬送用台車を分離して高速で搬送して前記搬送用台車群の後端に連結する返送ラインを設け、この返送ライン上で、前記搬送用台車群から分離した単体の前記搬送用台車に対する前記被搬送物の卸し作業及び新しい被搬送物の積込み作業を行うことを特徴とする。   In order to solve the above problems, the conveyor device according to the present invention forms a continuous work floor on which an operator rides a part assembling work while transporting a transport carriage carrying a transported object along a transport path. A conveyor device, wherein each of the transport carriages is positioned on the front or rear side in the transport direction of one or a plurality of carriages and relative to the carriage and about a vertical axis. It is constituted by a connecting pedestal body that is connected to each other, and the upper surface of the pedestal body and the upper surface of the connecting pedestal body are substantially the same horizontal plane, and provided with a connecting means for connecting between the transfer trolleys positioned before and after the transfer direction, A plurality of transfer carriages are connected by the connecting means and arranged as a transfer carriage group on a transfer path including a curved path, and while the transfer carriage group is transferred at a constant speed, the upper surfaces of the carriage and the connecting carriage bodies The work floor and A return line that constitutes a work line for performing the parts assembling work, and separates the transport carriage at the front end in the transport direction of the transport carriage group and transports it at a high speed to connect to the rear end of the transport carriage group And carrying out a work for wholesale of the object to be transported and a work for loading a new object to be transported to the single transport carriage separated from the group of transport carriages on the return line.

このような構成によれば、搬送用台車の各々を、単又は複数の台車体及び前記台車体の搬送方向前側又は後側に位置して前記台車体と垂直軸まわりに相対回動可能に連結された連結台車体により構成し、前記台車体の上面及び前記連結台車体の上面を略同一水平面としているので、搬送用台車の複数を連結手段により連結して搬送用台車群としたものの台車体及び連結台車体の上面を作業者が乗って部品組付け作業を行う連続した作業床とすることができるとともに、このような搬送用台車群を曲線状経路を含む搬送経路に配置することができる。
したがって、曲線状経路においても部品組付け作業を行うことができるため、作業効率及びスペース効率を向上することができる。
その上、被搬送物の積み卸し作業が、搬送用台車群から分離した単体の前記搬送用台車に対して返送ライン上で行われるので、被搬送物の積み卸し作業の際に作業ライン上の搬送用台車群を停止させる必要がなく、作業ライン上では搬送用台車群を定速で搬送しながら作業を行うことができるため、さらに作業効率が高くなる。
その上さらに、作業ラインにおける搬送用台車群は、前後の搬送用台車が連結手段により連結されているので、搬送速度の変動等があっても前後の搬送用台車間に隙間が生じることがないため、作業者が乗る連続した作業床(作業平面)を確実に形成することができる。
According to such a configuration, each of the transport carts is connected to the single or multiple cart bodies and the front or rear side in the transport direction of the cart bodies so as to be rotatable relative to the cart bodies around a vertical axis. Since the upper surface of the carriage body and the upper surface of the linkage carriage body are substantially on the same horizontal plane, the carriage body of the carriage carriage group is formed by connecting a plurality of carriage trucks with coupling means. In addition, the upper surface of the connecting pedestal vehicle body can be a continuous work floor on which an operator rides a part assembling work, and such a transportation carriage group can be arranged on a conveyance path including a curved path. .
Therefore, since the parts assembling work can be performed also in the curved path, the work efficiency and the space efficiency can be improved.
In addition, since the unloading work of the transported object is performed on the return line for the single transporting carriage separated from the transporting carriage group, the unloading work on the work line is performed during the unloading work of the transported object. Since it is not necessary to stop the transport carriage group and the work can be performed while transporting the transport carriage group at a constant speed on the work line, the work efficiency is further increased.
In addition, since the front and rear transport carts are connected by the connecting means in the transport line group on the work line, there is no gap between the front and rear transport carts even if there is a change in transport speed or the like. Therefore, it is possible to reliably form a continuous work floor (work plane) on which an operator rides.

ここで、前記搬送用台車を搬送経路に沿ってガイドするガイドレールが、前記搬送用台車の幅方向中央部下方に位置する水平ローラをガイドする搬送方向左右のガイド片であり、前記連結手段が、搬送方向前後に位置する前記搬送用台車の一方から他方に向かう連結ロッドの遊端部に水平揺動可能に取り付けられた揺動片に形成された鉤状係合部を、前記搬送用台車の他方に取り付けられた前記水平ローラの支軸に係合するものであり、前記作業ラインの少なくとも前記曲線状経路では、前記揺動片が前記左右のガイド片の間に位置すると好ましい。
このような構成によれば、少なくとも曲線状経路において、連結手段の揺動片が左右のガイド片の間に位置するので、揺動片の水平揺動が規制されることから、連結ロッドに振動や衝撃が作用した場合であっても揺動片の鉤状係合部と水平ローラの支軸との係合が外れることがないため、搬送方向前後に位置する搬送用台車間の連結手段による連結を安定かつ確実に行うことができる。
その上、連結手段が、連結ロッドの遊端部に水平揺動可能に取り付けられた揺動片に形成された鉤状係合部を水平ローラの支軸に係合する簡素な構成であるため、製造コストを低減することができる。
Here, the guide rail that guides the transport carriage along the transport path is a guide piece on the left and right in the transport direction that guides a horizontal roller located below the center in the width direction of the transport carriage, and the connecting means A hook-like engagement portion formed on a swinging piece attached to a free end portion of a connecting rod directed from one side to the other of the transporting cart located in the front and back in the transporting direction so as to be horizontally swingable. It is preferable that the swing piece is located between the left and right guide pieces in at least the curved path of the work line.
According to such a configuration, since the swing piece of the connecting means is located between the left and right guide pieces at least in the curved path, the horizontal swing of the swing piece is restricted, so that the connecting rod vibrates. Even when an impact is applied, the engagement between the hook-shaped engagement portion of the swinging piece and the support shaft of the horizontal roller is not disengaged. Connection can be performed stably and reliably.
In addition, the connecting means has a simple configuration in which the hook-shaped engaging portion formed on the swinging piece attached to the free end portion of the connecting rod so as to be horizontally swingable is engaged with the support shaft of the horizontal roller. The manufacturing cost can be reduced.

また、前記搬送用台車を搬送経路に沿ってガイドするガイドレールが、前記搬送用台車の幅方向中央部下方に位置する水平ローラをガイドする搬送方向左右のガイド片であり、前記連結手段が、搬送方向前後に位置する前記搬送用台車の一方に設けられた上下方向にスライド可能な連結ピンを前記搬送用台車の他方に形成された係合穴に挿入するものであり、前記連結手段による連結位置を前記搬送用台車の一方の前記水平ローラの真上とし、前記連結位置に近い前記搬送用台車の他方の水平ローラの位置を上側に転位させ、前記曲線状経路では、前記上側に転位させた水平ローラと干渉しないように前記ガイドレールの内側のガイド片の上部を切り欠いてなると好ましい。
このような構成によれば、連結手段の上下方向にスライド可能な連結ピンを係合穴に挿入した状態で前後の搬送用台車が安定かつ確実に連結されるとともに、前後の搬送用台車を1本の連結ピンで繋ぐ構成であることから、連結部の強度を大きくすることが容易であるため、特に、搬送用台車群を構成する搬送用台車の数が多く、前端の搬送用台車に駆動力を付与して搬送用台車群を牽引駆動する場合において、非常に大きな強度が必要になる前端の搬送用台車と後続の搬送用台車との連結部の強度確保が容易になる。
その上、連結ピン及び係合穴の連結位置が前後の搬送用台車の一方の水平ローラの真上であることから、この水平ローラの軸芯まわりに前後の搬送用台車が相対的に回動するため、作業床(作業平面)における水平方向に相対的に回動する部分の隙間を小さくすることができるとともに、搬送用台車の側面を被駆動面としてフリクションローラ式駆動装置により駆動する際における前記被駆動面の繋がりを良くすることができる。
その上さらに、前記連結位置の真下の水平ローラ近くの水平ローラを上側に転位させるとともに、曲線状経路ではガイドレールの内側のガイド片の上部を切り欠いているため、曲線状経路においても、連結位置の真下の水平ローラをガイドレールによりガイドしながら、上側に転位させた水平ローラとガイドレールとの干渉を防止して搬送用台車群の安定かつ確実な搬送が可能になる。
Further, the guide rail that guides the transport carriage along the transport path is a guide piece on the left and right in the transport direction that guides a horizontal roller located below the center in the width direction of the transport carriage, and the connecting means is A connecting pin provided on one side of the transporting carriage located in the front and rear of the transporting direction and slidable in the vertical direction is inserted into an engagement hole formed on the other side of the transporting carriage, and connected by the connecting means. The position is set directly above one of the horizontal rollers of the transfer carriage, the position of the other horizontal roller of the transfer carriage close to the connection position is shifted upward, and the position is shifted upward in the curved path. It is preferable to cut out the upper part of the guide piece inside the guide rail so as not to interfere with the horizontal roller.
According to such a configuration, the front and rear transport carts are connected stably and reliably with the connecting pin slidable in the vertical direction of the connecting means inserted into the engagement hole, and the front and rear transport carts are Since it is easy to increase the strength of the connecting part because it is connected with the connecting pins of the book, the number of transfer carriages that make up the transfer carriage group is particularly large, and it is driven to the transfer carriage at the front end. In the case of pulling and driving the transport carriage group by applying force, it is easy to secure the strength of the connecting portion between the front end transport carriage and the subsequent transport carriage, which requires very high strength.
In addition, since the connecting position of the connecting pin and the engagement hole is directly above one horizontal roller of the front and rear transport carts, the front and rear transport carts rotate relatively around the axis of the horizontal roller. Therefore, it is possible to reduce the gap of the part that rotates relatively in the horizontal direction on the work floor (work plane) and to drive the side surface of the transport carriage with the friction roller type driving device as the driven surface. The connection of the driven surfaces can be improved.
In addition, the horizontal roller near the horizontal roller just below the connection position is shifted upward, and the upper part of the guide piece on the inner side of the guide rail is cut out in the curved path. While the horizontal roller just below the position is guided by the guide rail, the horizontal roller shifted to the upper side and the guide rail are prevented from interfering with each other, so that the transport carriage group can be stably and reliably transported.

以上のように、本発明に係るコンベア装置によれば、曲線状経路を含む搬送経路に搬送用台車群を配置して、曲線状経路においても部品組付け作業を行うことができるため、作業効率及びスペース効率を向上することができ、被搬送物の積み卸し作業を搬送用台車群から分離した単体の搬送用台車に対して返送ライン上で行われるので、作業ライン上では搬送用台車群を定速で搬送しながら作業を行うことができるため、さらに作業効率が高くなり、作業ラインにおける搬送用台車群は、前後の搬送用台車が連結手段により連結されているので、搬送速度の変動等があっても前後の搬送用台車間に隙間が生じることがないため、作業者が乗る連続した作業床(作業平面)を確実に形成することができるという顕著な効果を奏する。   As described above, according to the conveyor apparatus according to the present invention, since the transportation carriage group can be arranged on the conveyance path including the curved path and the parts assembling work can be performed also on the curved path, the work efficiency is improved. And the space efficiency can be improved, and the unloading work of the object to be transported is performed on the return line with respect to the single transport cart separated from the transport cart group. Since the work can be performed while transporting at a constant speed, the work efficiency is further improved, and the transport carriage group in the work line is connected to the front and rear transport carriages by the connecting means, so the fluctuation of the transport speed, etc. Even if there is a gap, there is no gap between the front and rear transport carriages, so that it is possible to reliably form a continuous work floor (work plane) on which an operator rides.

なお、本明細書においては、被搬送物の搬送方向(図中矢印F参照。)を前、その反対側を後とし、前方へ向かって左右をいうものとし、左方から見た図を正面図とする。
Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments shown in the accompanying drawings, and includes all the embodiments that satisfy the requirements described in the claims. It is a waste.
In the present specification, the transport direction (see arrow F in the figure) of the object to be transported is the front, the opposite side is the rear, the left and right are the front, and the view seen from the left is the front. The figure.

図1の概略レイアウト図に示すように、本発明の実施の形態に係るコンベア装置は、被搬送物Wを搭載した非自走式の搬送用台車1,1,…を、フリクションローラ式駆動装置である送り装置T1,T2,T3により、直線状経路S1,S2及び曲線状経路C1,C2からなる無端状の搬送経路に沿って搬送するものであり、後述する連結手段C(図2及び図8の平面図参照。)により前後の搬送用台車1,1を連結してなる搬送用台車群Aを、曲線状経路C1を含む搬送経路に配置し、作業者が乗って部品組付け作業を行う連続した作業床(作業平面)B(図3及び図9の正面図参照。)を形成するようにして作業ラインL1としている。
また、搬送用台車群Aの前端の搬送用台車1は、搬送用台車群Aから分離され、分離された搬送用台車1を高速で搬送して搬送用台車群Aの後端に連結する返送ラインL2を、直線状経路S2の一部、曲線状経路C2及び直線状経路S1の一部により構成している。
さらに、返送ラインL2上に、被搬送物Wの積み卸し作業を行う積込ステーションST1及び卸しステーションST2を備えており、卸しステーションST2では、搬送用台車群Aから分離した単体の搬送用台車1から被搬送物Wを卸す作業が行われ、積込ステーションST1では、空荷になった単体の搬送用台車1に新しい被搬送物Wを積み込む作業が行われる。
As shown in the schematic layout diagram of FIG. 1, the conveyor apparatus according to the embodiment of the present invention includes a friction roller type driving device that includes a non-self-propelled transport carriage 1, 1. Are transported along an endless transport path composed of linear paths S1, S2 and curved paths C1, C2 by a feeding device T1, T2, T3. 8)), the transport carriage group A formed by connecting the front and rear transport carriages 1 and 1 is arranged on the transport path including the curved path C1, and the operator gets on the parts assembly work. A work line L1 is formed so as to form a continuous work floor (work plane) B (see the front views of FIGS. 3 and 9) to be performed.
In addition, the transfer carriage 1 at the front end of the transfer carriage group A is separated from the transfer carriage group A, and the separated transfer carriage 1 is transferred at high speed and connected to the rear end of the transfer carriage group A. The line L2 is configured by a part of the linear path S2, a curved path C2, and a part of the linear path S1.
In addition, on the return line L2, a loading station ST1 and a wholesale station ST2 for loading and unloading the articles W to be conveyed are provided. In the wholesale station ST2, a single conveyance carriage 1 separated from the conveyance carriage group A is provided. The work to unload the transported object W is performed, and at the loading station ST1, the work of loading the new transported object W onto the single transport cart 1 that has become empty is performed.

ここで、搬送用台車群Aの搬送は、定速搬送用送り装置T1により行われる。すなわち、定速搬送用送り装置T1のバックアップローラ17B,…により反力を受け止めながら、定速搬送用送り装置T1のフリクションローラ17A,…を前端の搬送用台車1の側面(図2及び図8の被駆動面H参照。)に圧接して前端の搬送用台車1を駆動することにより、後続の搬送用台車1,1,…が牽引され、搬送用台車群Aは一体となって定速で搬送される。
また、定速搬送用送り装置T1よりも僅かに低速とされたブレーキ用送り装置T3のフリクションローラ17Aを搬送用台車群Aの後端の搬送台車1の側面に圧接することにより、搬送用台車群A全体に引張力が作用することで、台車群A内の搬送用台車1同士のがたつきが発生しない効果がある。
さらに、上述のように搬送用台車群Aから分離された単体の搬送用台車1の搬送は、高速搬送用送り装置T2により、そのフリクションローラ17Aを搬送用台車1の側面に圧接することにより行われ、積込ステーションST1及び卸しステーションST2では、これらの所定位置で搬送用台車1を停止させた状態にして被搬送物Wの積み卸し作業を行う。
さらにまた、積込ステーションST1で新しい被搬送物Wの積み込み作業が行われた搬送用台車1を高速搬送用送り装置T2により高速で搬送して搬送用台車群Aの後端に連結する際には、高速搬送用送り装置T2を低速運転に変速することで、高速で搬送された搬送用台車1を減速させながら後述する連結手段Cにより搬送用台車群Aの後端に連結する。
Here, the conveyance carriage group A is conveyed by a constant-speed conveyance feeder T1. That is, while the reaction force is received by the backup rollers 17B of the constant-speed conveyance feeder T1, the friction rollers 17A of the constant-speed conveyance feeder T1 are moved to the side surface of the conveyance carriage 1 at the front end (FIGS. 2 and 8). .. Are driven in contact with the driven surface H, and the subsequent transport carts 1, 1,... Are pulled, and the transport cart group A is integrated at a constant speed. It is conveyed by.
Further, the friction roller 17A of the brake feeding device T3, which is slightly lower in speed than the constant-speed conveying feeder T1, is brought into pressure contact with the side surface of the conveying cart 1 at the rear end of the conveying cart group A, whereby the conveying cart. Since the tensile force acts on the entire group A, there is an effect that the transport carts 1 in the cart group A do not rattle.
Further, the conveyance of the single conveyance carriage 1 separated from the conveyance carriage group A as described above is performed by pressing the friction roller 17A against the side surface of the conveyance carriage 1 by the high-speed conveyance feeder T2. At the loading station ST1 and the wholesale station ST2, the unloading work of the transported object W is performed with the transport carriage 1 stopped at these predetermined positions.
Furthermore, when the transport carriage 1 on which the new work W has been loaded at the loading station ST1 is transported at a high speed by the high-speed transport feeder T2 and connected to the rear end of the transport carriage group A. Shifts the high-speed conveyance feeder T2 to a low-speed operation, thereby connecting the conveyance carriage 1 conveyed at high speed to the rear end of the conveyance carriage group A by connection means C described later.

The first connecting base body 2A and the second connecting base body 2B are connected to the base bodies 1A and 1B so as to be rotatable relative to the base bodies 1A and 1B. The upper surface and the upper surfaces of the connecting base vehicle bodies 2A and 2B are substantially the same horizontal plane.
In the first vehicle body 1A and the second vehicle body 1B, a frame body is fixed to the lower surface of a plate member having a generally oval shape in plan view with arcs in the front and rear, and traveling wheels 6A, 6A,. It is done.
In addition, the first connecting base body 2A and the second connecting base body 2B have a frame fixed to the lower surface of a substantially drum-shaped plate member in plan view with front and rear arc-shaped concave portions, and traveling wheels 6B and 6B on the left and right. Is attached to the lower surface of the plate member on the first connecting base vehicle body 2A on the front side, and the second connecting base vehicle body 2B on the rear side is attached to the lower surface of the plate member. A long connecting rod 4 is fixed in the front-rear direction.

第1連結台車体2Aの連結ロッド3の前端部は第1台車体1Aの後部幅方向中央と、連結ロッド3の後端部は第2台車体1Bの前部幅方向中央と、それぞれ垂直軸まわりに相対回動可能に連結され、第2連結台車体2Bの連結ロッド4の前端部は第2台車体1Bの後部幅方向中央と垂直軸まわりに相対回動可能に連結される。
また、第1台車体1Aの前部幅方向中央下方には水平ローラ5Aが取り付けられ、第1連結台車体2Aの連結ロッド3の前後端部下方には、それぞれ水平ローラ5B,5Cが取り付けられ、第2連結台車体2Bの連結ロッド4の前後端部下方には、それぞれ水平ローラ5D,5Eが取り付けられる。
さらに、第2連結台車体2Bの連結ロッド4の後端部には揺動片8が取り付けられ、この揺動片8と第1台車体1Aの前部幅方向中央下方の水平ローラ5Aの支軸Eとが、前後の搬送用台車1,1を連結する連結手段Cを構成する。
The front end of the connecting rod 3 of the first connecting vehicle body 2A is the vertical center of the first vehicle body 1A, and the rear end of the connecting rod 3 is the vertical center of the second vehicle body 1B. The front end of the connecting rod 4 of the second connecting vehicle body 2B is connected so as to be relatively rotatable around the center of the rear width direction of the second vehicle body 1B and the vertical axis.
In addition, a horizontal roller 5A is attached below the center of the front width direction of the first vehicle body 1A, and horizontal rollers 5B and 5C are attached below the front and rear ends of the connecting rod 3 of the first connection vehicle body 2A. Horizontal rollers 5D and 5E are respectively attached below the front and rear end portions of the connecting rod 4 of the second connecting base vehicle body 2B.
Further, a swing piece 8 is attached to the rear end portion of the connecting rod 4 of the second connecting base vehicle body 2B. The swing piece 8 and the horizontal roller 5A below the center in the front width direction of the first base car body 1A are supported. The shaft E constitutes a connecting means C that connects the front and rear transport carts 1, 1.

図3の正面図及び図4の前方から見た縦断正面図に示すように、床面FLに固定されたヨークY,Y,…により左右の走行レールR,R及びガイドレールGが固定され、走行レールR,R上を走行車輪6A,6A,…及び6B,6B,…が転動するとともに、ガイドレールGの左右のガイド片7A,7Bにより水平ローラ5A,5B,5C,5D,5Eがガイドされるため、第1台車体1A上方の被搬送物支持台Dに被搬送物Wが搭載された搬送用台車1,1,…(搬送用台車群A)は、前記搬送経路に沿って移動する。   As shown in the front view of FIG. 3 and the longitudinal front view seen from the front of FIG. 4, the left and right traveling rails R, R and the guide rail G are fixed by yokes Y, Y,. The rolling wheels 6A, 6A,... And 6B, 6B,... Roll on the traveling rails R, R, and the horizontal rollers 5A, 5B, 5C, 5D, 5E are moved by the left and right guide pieces 7A, 7B of the guide rail G. Since the guided vehicle 1 is guided, the transporting carriages 1, 1,... (The transporting carriage group A) in which the transported object W is mounted on the transported object support base D above the first car body 1A are along the transport path. Moving.

次に、連結手段Cの構成の詳細について説明する。
図2の平面図、図5及び図6の横断平面図並びに図7の縦断正面図に示すように、第2連結台車体2Bの連結ロッド4の後端部には、垂直軸(水平ローラ5Eの軸芯)まわりに揺動可能な揺動片8が取り付けられ、揺動片8には鉤状係合部8Aが形成されており、揺動片8はねじりコイルばね9により弾性付勢されているため、当止片8Dがストッパ10により当て止めされて揺動片8が後方に延びた状態が保持される。
したがって、例えば図2の搬送用台車1に対して、後方から搬送用台車1が接近すると、水平ローラ5Aの支軸Eが揺動片8の斜面に当接して前記弾性付勢力に抗して揺動片8を揺動させ、揺動片8の鉤状係合部8Aに支軸Eが係合するため、前後の搬送用台車1,1が連結された図6及び図7の状態になる。
また、このような連結手段Cの連結は、図6に示す被操作片8B先端の被操作ローラ8Cを図示しないカムレール等により操作して二点鎖線のように揺動させることにより解除することができる。
Next, details of the configuration of the connecting means C will be described.
As shown in the plan view of FIG. 2, the cross-sectional plan views of FIGS. 5 and 6, and the longitudinal front view of FIG. 7, the rear end portion of the connecting rod 4 of the second connecting base body 2B has a vertical shaft (horizontal roller 5E). Oscillating piece 8 is attached to the oscillating piece 8, and a hook-like engaging portion 8 A is formed on the oscillating piece 8. The oscillating piece 8 is elastically biased by a torsion coil spring 9. Therefore, the state where the stopper piece 8D is stopped by the stopper 10 and the swing piece 8 extends rearward is maintained.
Therefore, for example, when the carriage 1 approaches from the rear with respect to the carriage 1 shown in FIG. 2, the support shaft E of the horizontal roller 5A comes into contact with the inclined surface of the swing piece 8 and resists the elastic biasing force. Since the swing piece 8 is swung and the support shaft E is engaged with the hook-like engagement portion 8A of the swing piece 8, the front and rear transport carriages 1, 1 are connected to each other as shown in FIGS. Become.
Further, such connection of the connecting means C can be released by operating the operated roller 8C at the tip of the operated piece 8B shown in FIG. 6 with a cam rail or the like (not shown) and swinging like a two-dot chain line. it can.

連結手段Cの連結は、図1の作業ラインL1の上流側(搬送用台車群Aの後端)で行えばよく、連結手段Cの連結の解除は、図1の作業ラインL1の下流側(搬送用台車群Aの前端)で行えばよいため、例えば作業ラインL1(作業ラインL1の経路全体ではなく、曲線状経路C1のみ等の一部であってもよい。)では、図6及び図7のように揺動片8をガイドレールGの左右のガイド片7A,7Bの間に位置させるように、左右のガイド片7A,7Bの高さを高くしておくことができる。
このようにすれば、揺動片8の水平揺動が規制されることから、連結ロッド4に振動や衝撃が作用した場合であっても揺動片8の鉤状係合部8Aと水平ローラ5Aの支軸Eとの係合が外れることがないため、前後に位置する搬送用台車1,1間の連結手段Cによる連結を安定かつ確実に行うことができる。
また、連結手段Cの連結の解除を行う箇所では、ガイド片7Aの高さを低くして図6の二点鎖線のように揺動片8を揺動させることができるようにすればよい。
以上のような連結手段Cの構成によれば、連結ロッド4の遊端部に水平揺動可能に取り付けられた揺動片8に形成された鉤状係合部8Aを水平ローラ5Aの支軸Eに係合する簡素な構成であるため、製造コストを低減することができる。
The connection of the connection means C may be performed on the upstream side of the work line L1 in FIG. 1 (the rear end of the transport carriage group A), and the connection of the connection means C is released on the downstream side of the work line L1 in FIG. For example, in the work line L1 (may be a part of only the curved path C1 instead of the entire path of the work line L1), it may be performed at the front end of the transport carriage group A. FIG. The height of the left and right guide pieces 7A and 7B can be increased so that the swing piece 8 is positioned between the left and right guide pieces 7A and 7B of the guide rail G as shown in FIG.
In this way, since the horizontal swing of the swing piece 8 is restricted, the hook-like engagement portion 8A of the swing piece 8 and the horizontal roller are applied even when vibration or impact is applied to the connecting rod 4. Since the engagement with the support shaft E of 5A is not disengaged, the connection by the connecting means C between the transport carriages 1 and 1 positioned in the front and rear can be performed stably and reliably.
Further, at the place where the connection of the connecting means C is released, the height of the guide piece 7A may be lowered so that the swing piece 8 can be swung as shown by the two-dot chain line in FIG.
According to the structure of the connecting means C as described above, the hook-like engaging portion 8A formed on the swinging piece 8 attached to the free end portion of the connecting rod 4 so as to be horizontally swingable is used as the support shaft of the horizontal roller 5A. Since it is a simple structure which engages with E, manufacturing cost can be reduced.

実施の形態2.
図8の平面図、図9の正面図及び図10(a)の前方から見た縦断正面図に示すように、本発明の実施の形態2に係る搬送用台車1の基本構成は実施の形態1と同様であるため、実施の形態1と同一又は実施の形態1に相当する部分には図2〜図4と同じ符号を付すことにより、これらの説明を省略する。実施の形態2において実施の形態1と構成が異なる主要な部分は、連結手段Cであるため、以下において、連結手段Cの構成の詳細について説明する。
Embodiment 2. FIG.
As shown in the plan view of FIG. 8, the front view of FIG. 9 and the longitudinal front view seen from the front of FIG. 10 (a), the basic configuration of the transport carriage 1 according to the second embodiment of the present invention is the embodiment. 1 are the same as those in the first embodiment, or parts corresponding to those in the first embodiment are denoted by the same reference numerals as those in FIGS. The main part of the second embodiment that differs from the first embodiment in the configuration is the connecting means C, and therefore the details of the configuration of the connecting means C will be described below.

図8の平面図、図11及び図12の横断平面図並びに図13の縦断正面図に示すように、搬送用台車1の第1台車体1Aの前部幅方向中央下方の水平ローラ5Aの上方(水平ローラ5Aの支軸の軸芯の真上)には、ガイド穴11Aによりガイドされて上下方向にスライド可能な連結ピン11が設けられており、連結ピン11は、第2連結台車体2Bの連結ロッド4の後端部に形成された上下方向の係合穴12に係合するため、連結手段Cによる前後の搬送用台車1,1の連結位置は、後方の搬送用台車1の第1台車体1Aの前部幅方向中央下方の水平ローラ5Aの真上となっている。
また、前端部が第1台車体1Aの枠体に固定され、略前後方向に延びて上下方向へ揺動する第1リンク13Aの後端部には、略上下方向へ延びる第2リンク13Bの下端部が連結され、第2リンク13Bの上端部には、前後方向に延びてその中間部が左右方向の水平支軸14により支持されて上下方向に揺動する第3リンク13Cの後端部が連結され、第3リンク13Cの前端部が連結ピン11の上端部に連結される。
As shown in the plan view of FIG. 8, the cross-sectional plan views of FIGS. 11 and 12, and the longitudinal front view of FIG. 13, above the horizontal roller 5A below the center in the front width direction of the first vehicle body 1A of the transport carriage 1 A connecting pin 11 that is guided by the guide hole 11A and is slidable in the vertical direction is provided (above the axis of the support shaft of the horizontal roller 5A). The connecting pin 11 is connected to the second connecting base body 2B. In order to engage with the vertical engagement hole 12 formed at the rear end of the connecting rod 4, the connecting position of the front and rear transport carts 1, 1 by the connecting means C is the same as that of the rear transport cart 1. It is directly above the horizontal roller 5A below the center in the front width direction of the single vehicle body 1A.
Further, the front end portion is fixed to the frame body of the first vehicle body 1A, and the rear end portion of the first link 13A that extends substantially in the front-rear direction and swings in the up-down direction has the second link 13B extending in the substantially up-down direction. The lower end is connected, and the rear end of the third link 13C that extends in the front-rear direction and is supported by the horizontal support shaft 14 in the left-right direction and swings in the up-down direction at the upper end of the second link 13B. Are connected, and the front end of the third link 13 </ b> C is connected to the upper end of the connecting pin 11.

さらに、第3リンク13Cの前端部と水平支軸14との間に引張コイルばね15の一端部が掛止され、引張コイルばね15の他端部は第1台車体1Aの枠体に固定されるため、引張コイルばね15の弾性付勢力により連結ピン11が係合穴12に係合した状態が保持され、第1リンク13A及び第2リンク13Bの連結軸に取り付けられた被操作ローラ16を操作することにより、連結ピン11をガイド穴11Aに沿って昇降させることができる。
したがって、例えば図8の搬送用台車1に対して、後方から搬送用台車1が接近する際に、図示しないカムレール等により被操作ローラ16を押し下げて、図13の二点鎖線のように引張コイルばね15の弾性付勢力に抗して連結ピン11を上昇させた状態にしておき、連結ピン11とガイド穴11Aとの上下方向位置が合った状態で、カムレール等による被操作ローラ16の操作を解除することにより、引張コイルばね15の弾性付勢力により連結ピン11が下降して係合穴12に係合した状態、すなわち前後の搬送用台車1,1が連結された図12及び図13の状態になる。
また、このような連結手段Cの連結は、図12及び図13に示す被操作片16を上述のように操作して図13の二点鎖線のように連結ピン11を上昇させることにより解除することができる。
Further, one end portion of the tension coil spring 15 is hooked between the front end portion of the third link 13C and the horizontal support shaft 14, and the other end portion of the tension coil spring 15 is fixed to the frame body of the first vehicle body 1A. Therefore, the state in which the connecting pin 11 is engaged with the engaging hole 12 by the elastic biasing force of the tension coil spring 15 is maintained, and the operated roller 16 attached to the connecting shaft of the first link 13A and the second link 13B is moved. By operating, the connecting pin 11 can be moved up and down along the guide hole 11A.
Therefore, for example, when the transportation carriage 1 approaches from the rear side with respect to the transportation carriage 1 of FIG. 8, the operated roller 16 is pushed down by a cam rail or the like (not shown), and the tension coil as shown by a two-dot chain line in FIG. The operation of the operated roller 16 by a cam rail or the like is performed with the connecting pin 11 raised against the elastic biasing force of the spring 15 and the vertical position of the connecting pin 11 and the guide hole 11A being aligned. By releasing, the connecting pin 11 is lowered by the elastic biasing force of the tension coil spring 15 and engaged with the engagement hole 12, that is, the front and rear transport carriages 1, 1 are connected as shown in FIGS. It becomes a state.
Further, such connection of the connecting means C is released by operating the operated piece 16 shown in FIGS. 12 and 13 as described above and raising the connecting pin 11 as shown by a two-dot chain line in FIG. be able to.

ここで、第2連結台車体2Bの連結ロッド4の後端部に形成された上下方向の係合穴12の前側の水平ローラ5E(連結手段Cによる前記連結位置に近い水平ローラ5E)の位置を、図9及び図13に示すように上側に転位させているとともに、曲線状経路C1ではガイドレールGの内側のガイド片7Aの上部を図10(b)の前方から見た要部拡大縦断正面図に示すように切り欠いているため、図11に示す曲線状経路C1においても、前後の搬送用台車1,1の連結位置の真下の水平ローラ5AをガイドレールGによりガイドしながら、上側に転位させた水平ローラ5EとガイドレールGとの干渉を防止して搬送用台車群Aの安定かつ確実な搬送が可能になる。   Here, the position of the horizontal roller 5E on the front side of the vertical engagement hole 12 formed in the rear end portion of the connecting rod 4 of the second connecting base vehicle body 2B (the horizontal roller 5E close to the connecting position by the connecting means C). 9 and FIG. 13 is shifted upward, and in the curved path C1, the upper part of the guide piece 7A on the inner side of the guide rail G is viewed from the front of FIG. Since it is notched as shown in the front view, the horizontal roller 5A just below the connection position of the front and rear transport carriages 1 and 1 is guided by the guide rail G in the curved path C1 shown in FIG. The horizontal roller 5E that has been shifted to the guide rail G and the guide rail G are prevented from interfering with each other, so that the transport carriage group A can be transported stably and reliably.

以上のような連結手段Cの構成によれば、連結手段Cの上下方向にスライド可能な連結ピン11を係合穴12に挿入した状態で前後の搬送用台車1,1が安定かつ確実に連結されるとともに、前後の搬送用台車1,1を1本の連結ピン11で繋ぐ構成であることから、連結部の強度を大きくすることが容易であるため、特に、搬送用台車群Aを構成する搬送用台車1,1,…の数が多く、定速搬送用送り装置T1により前端の搬送用台車1に駆動力を付与して搬送用台車群Aを牽引駆動する場合において、非常に大きな強度が必要になる前端の搬送用台車1と後続の搬送用台車1との連結部の強度確保が容易になる。
また、連結ピン11及び係合穴12の連結位置が前後の搬送用台車1,1の一方の水平ローラ5Aの真上であることから、この水平ローラ5Aの軸芯まわりに前後の搬送用台車1,1が相対的に回動するため、作業床(作業平面)における水平方向に相対的に回動する部分の隙間を小さくすることができるとともに、搬送用台車1,1,…の側面を被駆動面H,H,…としてフリクションローラ式駆動装置により駆動する際における被駆動面H,H,…の繋がりを良くすることができる。
According to the configuration of the connecting means C as described above, the front and rear transport carriages 1 and 1 are connected stably and reliably with the connecting pin 11 slidable in the vertical direction of the connecting means C inserted into the engagement hole 12. In addition, since the front and rear transport carts 1 and 1 are connected by a single connecting pin 11, it is easy to increase the strength of the connecting portion. The number of transport carts 1, 1,... Is large, and in the case of driving the transport cart group A by applying a driving force to the transport cart 1 at the front end by the constant speed transport feeder T 1, it is very large. It is easy to ensure the strength of the connecting portion between the front-end transfer carriage 1 and the subsequent transfer carriage 1 that require strength.
Since the connecting position of the connecting pin 11 and the engagement hole 12 is directly above one horizontal roller 5A of the front and rear transport carts 1, 1, the front and rear transport carts around the axis of the horizontal roller 5A. 1 and 1 relatively rotate, so that the gap between the relatively rotating portions in the horizontal direction on the work floor (work plane) can be reduced, and the side surfaces of the transport carriages 1, 1,. It is possible to improve the connection of the driven surfaces H, H,... When driven by the friction roller type driving device as the driven surfaces H, H,.

以上の説明においては、搬送用台車1が、図2及び図8のように、2個の台車体(第1台車体1A及び第2台車体1B)と、2個の連結台車体(第1連結台車体2A及び第2連結台車体2B)により構成される場合を示したが、搬送用台車1を1個の台車体及び連結台車体により構成してもよく、3個以上の台車体及び連結台車体により構成してもよい。
また、前後の搬送用台車1,1に備える連結手段Cは、前後の搬送用台車1,1を連結するための相対的なものであるため、搬送用台車1の前部に備える連結手段の構成と後部に備える連結手段を入れ替えて実施することもできるとともに、例えば図2及び図8に示す搬送用台車1の搬送方向を逆方向としてもよい。
In the above description, as shown in FIGS. 2 and 8, the transport carriage 1 includes two carriage bodies (first carriage 1A and second carriage 1B) and two connection carriage bodies (first Although the case where it is configured by the connecting base body 2A and the second connecting base body 2B) is shown, the transporting carriage 1 may be configured by one base body and a connecting base body, and three or more base bodies and You may comprise a connection stand vehicle body.
Further, since the connecting means C provided in the front and rear transport carts 1 and 1 are relative for connecting the front and rear transport carts 1 and 1, the connecting means C provided in the front portion of the transport cart 1 While the configuration and the connecting means provided at the rear part can be exchanged, for example, the transport direction of the transport carriage 1 shown in FIGS. 2 and 8 may be reversed.

以上のような構成のコンベア装置の構成によれば、搬送用台車1の各々を、単又は複数の台車体(例えば、台車体1A,1B)及び前記台車体の搬送方向前側又は後側に位置して前記台車体と垂直軸まわりに相対回動可能に連結された連結台車体(例えば、連結台車体2A,2B)により構成し、前記台車体の上面及び前記連結台車体の上面を略同一水平面としているので、搬送用台車1の複数を連結手段Cにより連結して搬送用台車群Aとしたものの台車体及び連結台車体の上面を作業者が乗って部品組付け作業を行う連続した作業床(作業平面)Bとすることができるとともに、このような搬送用台車群Aを曲線状経路を含む搬送経路に配置することができる。
したがって、曲線状経路においても部品組付け作業を行うことができるため、作業効率及びスペース効率を向上することができる。
また、被搬送物Wの積み卸し作業が、搬送用台車群Aから分離した単体の搬送用台車1に対して返送ラインL2上で行われるので、被搬送物Wの積み卸し作業の際に作業ラインL1上の搬送用台車群Aを停止させる必要がなく、作業ラインL1上では搬送用台車群Aを定速で搬送しながら作業を行うことができるため、さらに作業効率が高くなる。
さらに、作業ラインL1における搬送用台車群Aは、前後の搬送用台車1,1が連結手段Cにより連結されているので、搬送速度の変動等があっても前後の搬送用台車間に隙間が生じることがないため、作業者が乗る連続した作業床(作業平面)Bを確実に形成することができる。
According to the configuration of the conveyor apparatus configured as described above, each of the transport carriages 1 is positioned on one or a plurality of carriage bodies (for example, the carriage bodies 1A and 1B) and on the front side or the rear side in the conveyance direction of the carriage bodies. And a connecting base body (for example, connecting base bodies 2A and 2B) connected to the base body so as to be rotatable about a vertical axis, and the upper surface of the base body and the upper surface of the connecting base body are substantially the same. Since it is a horizontal plane, a plurality of transport carts 1 are connected by a connecting means C to form a transport cart group A, and a continuous operation in which an operator rides parts on the top surface of the cart body and the connecting cart body is performed. The floor (working plane) B can be used, and such a transport carriage group A can be arranged on a transport path including a curved path.
Therefore, since the parts assembling work can be performed also in the curved path, the work efficiency and the space efficiency can be improved.
In addition, since the unloading work of the transported object W is performed on the return line L2 with respect to the single transporting carriage 1 separated from the transporting carriage group A, the work is performed during the unloading work of the transported object W. There is no need to stop the transport carriage group A on the line L1, and the work can be performed while transporting the transport carriage group A at a constant speed on the work line L1, so that the work efficiency is further increased.
Further, since the front and rear transport carts 1 and 1 are connected by the connecting means C in the work line L1, the gap between the front and rear transport carts is maintained even if the transport speed varies. Since it does not occur, a continuous work floor (work plane) B on which an operator rides can be reliably formed.
