Description

本発明は、コンベア搬送されるパレットを、搬送途中で回転させる機構を備えたパレット搬送装置に関する。   The present invention relates to a pallet conveying apparatus provided with a mechanism for rotating a pallet conveyed on a conveyor in the middle of conveyance.

搬送装置におけるパレットの回転機構は、工場の生産効率化が進むにつれ、益々重要になってきており、機構の簡略化、搬送速度の向上は、省エネやメンテナンス性において有利に働くことから、特に重要視されている。   The pallet rotation mechanism in the transport equipment is becoming more and more important as the production efficiency of factories progresses, and the simplification of the mechanism and the improvement in the transport speed are particularly important because they work in energy saving and maintainability. Is being viewed.

例えば、特許文献1には、チェーンコンベアによるパレット搬送において、パレットを搬送途中で押し上げ、チェーン駆動に使用しているモータの回転をクラッチにより回転装置の駆動につなげ、使用するモータの数を減らしパレット回転機構の簡略化を図った技術が開示されている。   For example, in Patent Document 1, in pallet transport by a chain conveyor, the pallet is pushed up in the middle of transport, the rotation of the motor used for chain drive is connected to the drive of the rotating device by a clutch, and the number of motors used is reduced. A technique that simplifies the rotation mechanism is disclosed.

特開平07−291449号公報JP 07-291449 A

しかしながら、特許文献1の技術は、パレット回転装置の駆動を、モータからクラッチに置き換えることで、装置全体のコストを下げるとともに、モータの制御数を減らしてはいるが、モータの代わりにクラッチを使用していることから、パレットを回転させるときには、駆動回転軸とクラッチの噛み合わせといった制御が必要になる。   However, the technology of Patent Document 1 replaces the drive of the pallet rotating device from a motor to a clutch, thereby reducing the overall cost of the device and reducing the number of motor controls, but using a clutch instead of a motor. Therefore, when the pallet is rotated, it is necessary to perform control such as meshing of the drive rotating shaft and the clutch.

更に、特許文献1の技術でパレットを回転させる一連の動作は、パレットを押し上げる、パレットを回転させる、パレットを降ろすとった流れであり、パレットを回転させる際は搬送路から一旦パレットを切り離す必要があり、パレット搬送を停止させることになるため、搬送速度全体を低下させることになる。   Furthermore, a series of operations for rotating the pallet by the technique of Patent Document 1 is a flow of pushing up the pallet, rotating the pallet, and lowering the pallet. When rotating the pallet, it is necessary to temporarily disconnect the pallet from the conveyance path. Yes, since pallet conveyance is stopped, the entire conveyance speed is reduced.

本発明は、上記の従来技術の問題点を解決するもので、パレット搬送装置において搬送途中でパレットを回転させる際の回転機構の簡略化かつ搬送速度向上を提供することを目的とする。   An object of the present invention is to solve the above-described problems of the prior art, and to provide a simplified rotation mechanism and an improved conveyance speed when a pallet is rotated during conveyance in a pallet conveyance device.

(2) The pallet transport device according to item (1), wherein the transport device has a plurality of support guides and slide guides.

本発明によれば、パレットの回転動作に必要な駆動装置としては、搬送用のモータのみでありコストを抑えることができ、搬送用のモータを制御するだけで回転動作を行えるためパレット回転機構を簡略化することもできる。   According to the present invention, the drive device necessary for the rotation operation of the pallet is only a conveyance motor, and the cost can be suppressed. Since the rotation operation can be performed only by controlling the conveyance motor, the pallet rotation mechanism is provided. It can also be simplified.

また、パレットは、ガイドに沿って回転し搬送しながら回転することになり、パレットは、搬送路から切り離されることなく常に搬送され続けるため、平均搬送速度を向上させることができる。   Further, the pallet is rotated while being conveyed along the guide and is rotated, and the pallet is always conveyed without being separated from the conveying path, so that the average conveying speed can be improved.

In the following, the range necessary for the description for achieving the object of the present invention is schematically shown, and the operation of rotating the pallet from the transfer position 1 to the transfer position 2 and from the transfer position 2 to the transfer position 3 is described. To do.

パレットの軸aが軸受けガイドAの窪みA1に接触するまで、パレットが直進し(図面にて上方向への移動)、接触するとパレットの軸aがパレットの回転軸となりパレットが反時計回りに回転し始める。
パレットが回転していくと、パレットの軸dが滑りガイドBの傾斜部B1に接触し、滑りガイドBに沿うように回転を続け、やがてパレットの軸bが軸受けガイドAの直線部A2に接触しパレットの回転角度が90°になったところでパレットの回転が止まり、回転の止まったパレットは各軸が、各ガイドの直線部A2、B2に沿いながら搬送位置2に搬送される。搬送位置2においてパレットは搬送位置1に置かれた状態から90°回転したことになる。
The pallet moves straight (moves upward in the drawing) until the pallet shaft a contacts the recess A 1 of the bearing guide A. When the pallet touches, the pallet shaft a becomes the pallet rotation axis and the pallet rotates counterclockwise. Start spinning.
As the pallet rotates, the pallet shaft d comes into contact with the inclined portion B 1 of the sliding guide B and continues to rotate along the sliding guide B. Eventually, the pallet shaft b becomes the straight portion A 2 of the bearing guide A. When the rotation angle of the pallet reaches 90 ° in contact with the pallet, the rotation of the pallet stops, and the pallet that has stopped rotating is transported to the transport position 2 along each axis along the straight portions A 2 and B 2 of each guide. . At the transfer position 2, the pallet is rotated 90 ° from the state where it is placed at the transfer position 1.

搬送位置2にあるパレットの軸bが軸受けガイドCの窪みC1に接触するまで、パレットが直進し接触すると、パレットの軸bがパレットの回転軸となりパレットが反時計回りに回転し始める。
パレットが回転していくとパレットの軸cが滑りガイドDの傾斜部D1に接触し、滑りガイドDに沿うように回転を続け、やがてパレットの軸d が軸受けガイドCの直線部C2に接触しパレットの回転角度が90°になったところでパレットの回転が止まり、回転の止まったパレットは各軸が、各ガイドの直線部C2、D2に沿いながら搬送位置3に搬送される。搬送位置3においてパレットは搬送位置1に置かれた状態から180°回転したことになる。
To the axis b of the pallet in the transport position 2 is in contact with the recess C 1 bearing guide C, and the pallet contacts straight, pallet axis b of the pallet is the rotation axis of the pallet starts to rotate counterclockwise.
As the pallet rotates, the pallet shaft c comes into contact with the inclined portion D 1 of the sliding guide D and continues to rotate along the sliding guide D. Eventually, the pallet shaft d contacts the linear portion C 2 of the bearing guide C. When the contact and the rotation angle of the pallet reach 90 °, the rotation of the pallet stops, and each axis of the pallet that has stopped rotating is transferred to the transfer position 3 along the straight portions C 2 and D 2 of each guide. At the transfer position 3, the pallet is rotated 180 ° from the state where it is placed at the transfer position 1.

このように本発明によれば、パレットの搬送力のみを動力源とし構造を簡略化した機構でパレットを90°ないし180°回転させて搬送することができる。   As described above, according to the present invention, the pallet can be conveyed by being rotated by 90 ° to 180 ° with a mechanism having a simplified structure using only the conveying force of the pallet as a power source.

またパレットは、いずれも搬送されながら回転するため、パレットは常に搬送方向に向かって動き続けることになり、パレットの搬送を一旦止める回転機構に比べ搬送速度の向上ができる。   In addition, since the pallets rotate while being transported, the pallet always continues to move in the transport direction, and the transport speed can be improved compared to a rotating mechanism that temporarily stops transport of the pallet.
