Description

【0001】
【発明の属する技術分野】
本発明は、小物部品整列装置に関するものである。
【0002】
【従来の技術】
例えば、プレス機でプレス成形されて搬送コンベヤによりプレス型内から連続的に搬出されてくる小物部品(プレス成形品)等は、向きを一方向に整えた上で所定の数量に揃えて収納容器に積み込む必要がある。
【0003】
ところが、搬送コンベヤ上の小物部品は、まちまちな姿勢のまま流れてくる為、搬送コンベヤ上から作業者が直接的に取り上げて収納容器に積み込むような作業を搬送速度に合わせて行うことは不可能であり、小物部品を一旦大きなパレットに収容させた後に、作業者が手作業で数を数えながら小物部品の向きを一方向に整えて所定の収納容器に積み替えるようにしている。
【0004】
【発明が解決しようとする課題】
しかしながら、大きなパレットに無造作に収容された多数の小物部品を一つ一つ手作業で取り出し、数を数えながら向きを一方向に整えて所定の収納容器に積み替える作業は非常に手間のかかる作業であり、多くの時間と労力を要するという問題があった。
【0005】
本発明は上述の実情に鑑みてなしたもので、多数の小物部品を搬送しながら同じ向きに整列し得るようにして、所定の収納容器に小物部品を積み込む作業に関する作業者の負担を軽減することを目的としている。
【0006】
【課題を解決するための手段】
本発明は、前端側の幅より後端側の幅の方が広く形成された小物部品を搬送コンベヤで搬送しながら同じ向きに整列させる小物部品整列装置であって、搬送コンベヤの搬送面上で該搬送コンベヤの送り方向上流側に向けハの字状に開いて小物部品を搬送コンベヤの幅方向中央付近に寄せる案内ゲートと、該案内ゲートの下流側で搬送コンベヤの左右の幅端部から中央側へ互い違いに張り出し且つその先端部に搬送面に対し直立させた丸棒を有する複数の方向転換ガイドアームと、該方向転換ガイドアームの下流側で搬送コンベヤの左右の幅端部から中央側へ互い違いに張り出し且つその先端部に搬送コンベヤの送り方向に沿う起立面を成して該起立面の前後端部を搬送コンベヤの反中央側へ反らせた平板を有する複数の方向規制ガイドアームとを備え、案内ゲート、方向転換ガイドアーム、方向規制ガイドアームの夫々が、搬送コンベヤの送り方向及び幅方向に位置調整可能に設けられていることを特徴とするものである。
【0007】
従って、本発明では、搬送コンベヤ上を搬送されてきた小物部品が、案内ゲートにより案内されて搬送コンベヤの幅方向中央付近に寄せられ、次いで、搬送コンベヤの左右の幅端部から中央側へ互い違いに張り出す方向転換ガイドアームの夫々と干渉しつつ各小物部品が搬送され、該各小物部品のうちの前端側を搬送コンベヤの送り方向に向けていないものが、その前端側が搬送コンベヤの送り方向に向かうように徐々に方向を転換される。
【0008】
即ち、小物部品の後端側は、その前端側より幅が広くなっていることから各方向転換ガイドアームの先端部の丸棒と干渉し易く、該丸棒と干渉した際には、その干渉位置を支点として反対側が搬送コンベヤの送り方向へ先行して流れる結果、小物部品の姿勢が前端側を搬送コンベヤの送り方向に向けた正しい姿勢に段階的に方向転換されていく。
【0009】
ここで、方向転換ガイドアームの先端部が、搬送面に対し直立させた丸棒となっていることは、小物部品と干渉した際における干渉位置を支点とした小物部品の方向転換性を高める上で非常に効果的である。
【0010】
そして、これら方向転換ガイドアームにより大まかに正しい姿勢に方向転換された各小物部品は、次の方向規制ガイドアームの夫々と干渉しつつ搬送され、該各方向規制ガイドアームの先端部の平板により、該平板の起立面に沿うように更に姿勢を整えられ、最終的に全ての小物部品が前端側を搬送コンベヤの送り方向に向けた正しい姿勢に修正されて整列される。
【0011】
ここで、方向規制ガイドアームの先端部が、搬送コンベヤの送り方向に沿う起立面を成して該起立面の前後端部を搬送コンベヤの反中央側へ反らせた平板となっていることは、既に大まかに正しい姿勢に方向転換されてしまっている各小物部品の姿勢を円滑に整える上で非常に効果的である。
【0013】
また、案内ゲート、方向転換ガイドアーム、方向規制ガイドアームの夫々が、搬送コンベヤの送り方向及び幅方向に位置調整可能に設けられているので、左右の案内ゲートを搬送コンベヤの送り方向に若干ずらして配置したり、左右の案内ゲートの相互間隔を調整したりすることが可能となり、しかも、方向転換ガイドアームや方向規制ガイドアームにおける先端部の丸棒や平板の張り出し位置や搬送コンベヤの送り方向における配置位置を任意に調整することが可能となる。
【0014】
【発明の実施の形態】
以下本発明の実施の形態を図面を参照しつつ説明する。
【0015】
図1〜図7は本発明の小物部品整列装置を実施する形態の一例を示すもので、図中1は作業台車2の上にフレーム3を介して搭載された搬送コンベヤを示し、この搬送コンベヤ1は、図示しないプレス機のプレス型内から連続的に搬出されてくる図4に示す如き小物部品4(前端側の幅xより後端側の幅yの方が広く形成された小物部品)を先端側(図1中における右側)で受けて基端側(図1中における左側)へ搬送するようになっており、搬送コンベヤ1の基端側まで搬送された小物部品4は、最終的に後述する部品回収装置5に回収されるようにしてある。
【0016】
そして、搬送コンベヤ1の左右の幅端部には、サポート6により搬送コンベヤ1の搬送面より高く支持されて該搬送コンベヤ1の送り方向へ延びる取付ロッド7が固定設置されており、この左右の取付ロッド7により、以下に詳述する如き案内ゲート8、方向転換ガイドアーム9、方向規制ガイドアーム10が夫々支持されて前記搬送コンベヤ1の搬送面上に浮上配置(搬送面にキズが付かない程度に摺接していても良い)されるようになっている。
【0017】
即ち、案内ゲート8は、搬送コンベヤ1の搬送面上で該搬送コンベヤ1の送り方向上流側に向けハの字状に開いて小物部品4を搬送コンベヤ1の幅方向中央付近に寄せるように対で配置されており、左右の取付ロッド7に対し基端部を取り付けたゲートアーム11の先端部により支持されるようになっている。
【0018】
また、方向転換ガイドアーム9は、前記案内ゲート8の下流側で搬送コンベヤ1の左右の幅端部から中央側へ互い違いに張り出すように配置され、その基端部を左右何れかの取付ロッド7に対し取り付けられており、その先端部には前記搬送コンベヤ1の搬送面に対し直立させた丸棒12(図6参照)が装着されている。
【0019】
更に、方向規制ガイドアーム10は、前述した方向転換ガイドアーム9の下流側で該各方向転換ガイドアーム9と同様に搬送コンベヤ1の左右の幅端部から中央側へ互い違いに張り出すように配置され、その基端部を左右何れかの取付ロッド7に対し取り付けられており、その先端部には前記搬送コンベヤ1の送り方向に沿う起立面を成して該起立面の前後端部を搬送コンベヤ1の反中央側へ反らせた平板13(図7参照)が装着されている。
【0020】
尚、先に説明したゲートアーム11の基端部、方向転換ガイドアーム9の基端部、方向規制ガイドアーム10の基端部の夫々と、左右の取付ロッド7との取り付け箇所の詳細は図5に示す通りであり、これらの何れの場合に関しても、互いに直角を成すように交差して上下二段に固着されたスリーブ部材14,15と、該各スリーブ部材14,15の円周方向適宜位置に半径方向に向け螺着されたロックねじ16,17とから成る位置調整手段18により相互の取り付けが行われるようにしてある。
【0021】
即ち、取付ロッド7に対し上段のスリーブ部材14を摺動自在に外嵌装着して適宜位置でロックねじ16を強く締め込むことにより搬送コンベヤ1の送り方向における位置を規定し、下段のスリーブ部材15に対しゲートアーム11の基端部、方向転換ガイドアーム9の基端部、方向規制ガイドアーム10の基端部の何れかを摺動自在に嵌挿して適宜位置でロックねじ17を強く締め込むことにより搬送コンベヤ1の幅方向への張り出し位置を規定するようにしてある。
【0022】
尚、左右の案内ゲート8の最下流位置における間口の間隔や、方向転換ガイドアーム9及び方向規制ガイドアーム10におけるジグザグ状に配置された相互の間隔については、小物部品4の詰まりを防止する観点から該小物部品4の最大寸法より大きく確保してある。
【0023】
更に、ここに図示している例では、搬送コンベヤ1の基端側となる作業台車2上に、前記小物部品4を回収する部品回収装置5が搭載されており、この部品回収装置5は、後述する如く、正しい姿勢に修正されて搬送コンベヤ1の基端側から送り出される小物部品4を、該小物部品4の孔4aに串棒19を挿し込んで回収し得るように構成されている。
【0024】
ここで、この串棒19は、搬送コンベヤ1の基端に対し若干離れた下方位置から斜め上方に立ち上がり、搬送コンベヤ1の基端から落下する寸前の小物部品4の孔4aに丁度挿し入れられるように形成されており、しかも、相互に約90゜向きを変えた位置に同様の串棒19を装備している。
【0025】
また、これらの対の串棒19はエアシリンダ20の伸縮作動により約90゜回転するようにした旋回台21の上に搭載されており、搬送コンベヤ1の基端下部に備えた光電管22(図2参照)により搬送コンベヤ1の基端から落ちる小物部品4の数を数え、その数が所定数に達した時に制御装置23により前記エアシリンダ20を駆動して串棒19を別の串棒19に切り換え且つ回転灯24を点灯させて作業者に知らせるようになっている。
【0026】
而して、以上に説明した如き小物部品整列装置によれば、搬送コンベヤ1上を搬送されてきた小物部品4が、案内ゲート8により案内されて搬送コンベヤ1の幅方向中央付近に寄せられ、次いで、搬送コンベヤ1の左右の幅端部から中央側へ互い違いに張り出す方向転換ガイドアーム9の夫々と干渉しつつ各小物部品4が搬送され、該各小物部品4のうちの前端側を搬送コンベヤ1の送り方向に向けていないものが、その前端側が搬送コンベヤ1の送り方向に向かうように徐々に方向を転換される(図1参照)。
【0027】
即ち、小物部品4の後端側は、その前端側より幅が広くなっていることから各方向転換ガイドアーム9の先端部の丸棒12と干渉し易く、該丸棒12と干渉した際には、その干渉位置を支点として反対側が搬送コンベヤ1の送り方向へ先行して流れる結果、小物部品4の姿勢が前端側を搬送コンベヤ1の送り方向に向けた正しい姿勢に段階的に方向転換されていく。
【0028】
ここで、方向転換ガイドアーム9の先端部が、搬送面に対し直立させた丸棒12となっていることは、小物部品4と干渉した際における干渉位置を支点とした小物部品4の方向転換性を高める上で非常に効果的である。
【0029】
そして、これら方向転換ガイドアーム9により大まかに正しい姿勢に方向転換された各小物部品4は、次の方向規制ガイドアーム10の夫々と干渉しつつ搬送され、該各方向規制ガイドアーム10の先端部の平板13により、該平板13の起立面に沿うように更に姿勢を整えられ、最終的に全ての小物部品4が前端側を搬送コンベヤ1の送り方向に向けた正しい姿勢に修正されて整列される。
【0030】
ここで、方向規制ガイドアーム10の先端部が、搬送コンベヤ1の送り方向に沿う起立面を成して該起立面の前後端部を搬送コンベヤ1の反中央側へ反らせた平板13となっていることは、既に大まかに正しい姿勢に方向転換されてしまっている各小物部品4の姿勢を円滑に整える上で非常に効果的である。
【0031】
そして、正しい姿勢に修正されて搬送コンベヤ1の基端側から送り出される小物部品4は、前述した部品回収装置5の串棒19により串刺し状に吊り下げられて良好に回収され、小物部品4を回収した数が所定数に達した時点でエアシリンダ20により別の串棒19に切り換えられて回収が継続される一方、回転灯24の点灯に気づいた作業者により所定数の小物部品4が串棒19から取り外されて所定の収納容器に積み込まれることになる。
【0032】
従って、上記形態例によれば、多数の小物部品4を搬送コンベヤ1にて搬送しながら同じ向きに整列させることができ、あとは同じ向きに整列した小物部品4を部品回収装置5で支障なく集めて、所定数に達した小物部品4を所定の収納容器に積み込むだけで作業が済むことになるので、小物部品4を所定の収納容器に積み込むために要する作業時間や労力を著しく削減することができ、作業者の負担を大幅に軽減することができる。
【0033】
また、特に本形態例においては、案内ゲート8、方向転換ガイドアーム9、方向規制ガイドアーム10の夫々が、先に図5にて説明した位置調整手段18により搬送コンベヤ1の送り方向及び幅方向に位置調整可能に設けられているので、左右の案内ゲート8を搬送コンベヤ1の送り方向に若干ずらして配置したり、左右の案内ゲート8の相互間隔を調整したりすることができ、しかも、方向転換ガイドアーム9や方向規制ガイドアーム10における先端部の丸棒12や平板13の張り出し位置や搬送コンベヤ1の送り方向における配置位置についても任意に調整することができるので、これらの配置条件を適宜に調整しながら小物部品4を試験的に流して試行錯誤を繰り返すことにより、小物部品4の形状や大きさ等に応じた最適な配置条件を簡単に見つけ出すことができる。
【0034】
例えば、左右の案内ゲート8を搬送コンベヤ1の送り方向に若干ずらして配置すると、小物部品4を搬送コンベヤ1の幅方向中央付近に寄せるべく左右の案内ゲート8の間口を狭めながらも小物部品4の詰まりを回避できるようにする上で有効であり、また、方向転換ガイドアーム9や方向規制ガイドアーム10におけるジグザグ状に配置された相互の間隔を、搬送コンベヤ1の送り方向上流側で比較的大きくとり、下流側に向かうにつれて徐々に狭めていくようにすると、小物部品4の姿勢を効率良く修正していく上で有効であるという知見が本発明者らにより既に得られているので、これらの配置条件の調整を小物部品4の形状や大きさ等に応じて適切に決定していくことが実用上重要となるのである。
【0035】
尚、本発明の小物部品整列装置は、上述の形態例にのみ限定されるものではなく、部品回収装置の併用は任意に選定できる事項であること、また、小物部品の形状は図示する例に限定されないこと、作業台車上に搭載しない固定設置タイプであっても良いこと、その他、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。
【0036】
【発明の効果】

BACKGROUND OF THE INVENTION
The present invention relates to an accessory parts alignment apparatus.
[0002]
[Prior art]
For example, small parts (press-molded products) that have been press-molded by a press machine and continuously carried out from the press mold by a conveyor are arranged in a single direction and aligned in a predetermined quantity. Need to be loaded into.
[0003]
However, since small parts on the transport conveyor flow in various postures, it is impossible for the operator to pick up directly from the transport conveyor and load it into the storage container according to the transport speed. Then, after the small parts are once stored in a large pallet, the operator arranges the small parts in one direction while counting the number manually, and reloads them into a predetermined storage container.
[0004]
[Problems to be solved by the invention]
However, it is very time-consuming to manually take out a large number of small parts stored on a large pallet one by one, arrange the direction in one direction while counting the number, and transfer them to the specified storage container. There was a problem that much time and labor were required.
[0005]
The present invention has been made in view of the above-described circumstances, and reduces the burden on the operator regarding the work of loading small parts into a predetermined storage container so that the small parts can be aligned in the same direction while being conveyed. The purpose is that.
[0006]
[Means for Solving the Problems]
The present invention relates to a small component aligning apparatus for aligning small components having a width wider on the rear end side than the width on the front end side in the same direction while being conveyed on the conveyance conveyor, on the conveyance surface of the conveyance conveyor. A guide gate that opens in the shape of a letter C toward the upstream side in the feed direction of the conveyor, and moves small parts to the vicinity of the center in the width direction of the conveyor, and the center from the left and right width ends of the conveyor on the downstream side A plurality of direction-changing guide arms that protrude alternately to the side and have a round bar that stands upright with respect to the conveying surface at the tip, and from the left and right width end portions of the conveying conveyor to the center side downstream of the direction-changing guide arm A plurality of direction regulating guide arms having flat plates extending alternately and having standing surfaces along the feeding direction of the transport conveyor at the leading ends thereof, and warping the front and rear ends of the rising surfaces toward the anti-center side of the transport conveyor The provided guidance gates, diverting guide arms, each of the direction restricting guide arm, is characterized in that is provided to be position adjustment in the feeding direction and the width direction of the conveyor.
[0007]
Therefore, in the present invention, the small parts that have been transported on the transport conveyor are guided by the guide gate and brought close to the center in the width direction of the transport conveyor, and then alternately shifted from the left and right width ends of the transport conveyor toward the center. Each small part is transported while interfering with each of the direction change guide arms protruding to the front, and the front end of each small part is not directed to the transport direction of the transport conveyor. The direction is gradually changed to head toward.
[0008]
That is, the rear end side of the accessory part is wider than the front end side thereof, so that it easily interferes with the round bar at the tip of each direction changing guide arm. As a result of the opposite side flowing in advance in the feed direction of the transport conveyor with the position as a fulcrum, the posture of the small parts is gradually changed to the correct posture with the front end side facing the feed direction of the transport conveyor.
[0009]
Here, the tip of the direction change guide arm is a round bar that stands upright with respect to the conveyance surface. This improves the direction changeability of the small part with the interference position as a fulcrum when it interferes with the small part. It is very effective.
[0010]
Then, each accessory component whose direction is roughly changed to a correct posture by these direction change guide arms is conveyed while interfering with each of the next direction restriction guide arms, and by the flat plate at the tip of each direction restriction guide arm, The posture is further adjusted so as to follow the upright surface of the flat plate, and finally, all small parts are corrected and aligned in a correct posture with the front end facing the feed direction of the conveyor.
[0011]
Here, the tip portion of the direction regulation guide arm is a flat plate in which the front and rear end portions of the rising surface are warped to the anti-center side of the conveying conveyor by forming the rising surface along the feeding direction of the conveying conveyor. This is very effective in smoothly adjusting the posture of each small component that has already been roughly changed to the correct posture.
[0013]
In addition, each of the guide gate, direction change guide arm, and direction regulation guide arm is provided so that its position can be adjusted in the transport conveyor feed direction and width direction, so the left and right guide gates are slightly shifted in the transport conveyor feed direction. And the distance between the left and right guide gates can be adjusted, and the protruding position of the round bar and flat plate at the tip of the direction change guide arm and direction control guide arm and the feed direction of the conveyor It is possible to arbitrarily adjust the arrangement position at.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0015]
FIGS. 1 to 7 show an example of an embodiment for carrying out the accessory component aligning apparatus of the present invention. In FIG. 1, reference numeral 1 denotes a transport conveyor mounted on a work carriage 2 via a frame 3. 1 is a small component 4 as shown in FIG. 4 continuously conveyed from a press die of a press machine (not shown) (small component having a width y on the rear end side wider than a width x on the front end side). 1 is received at the front end side (the right side in FIG. 1) and conveyed to the base end side (the left side in FIG. 1). The parts are collected by a parts collection device 5 described later.
[0016]
At the left and right width ends of the transfer conveyor 1, mounting rods 7 that are supported by the support 6 higher than the transfer surface of the transfer conveyor 1 and extend in the feed direction of the transfer conveyor 1 are fixedly installed. The mounting rod 7 supports a guide gate 8, a direction changing guide arm 9, and a direction regulating guide arm 10 as will be described in detail below, and floats on the conveying surface of the conveying conveyor 1 (the conveying surface is not damaged). It may be slid to the extent).
[0017]
That is, the guide gate 8 is opened in a C shape on the transport surface of the transport conveyor 1 toward the upstream side in the feed direction of the transport conveyor 1 so that the accessory part 4 is brought close to the center in the width direction of the transport conveyor 1. And is supported by the distal end portion of the gate arm 11 with the proximal end portion attached to the left and right attachment rods 7.
[0018]
Further, the direction change guide arms 9 are arranged so as to alternately protrude from the left and right width end portions of the transport conveyor 1 to the center side on the downstream side of the guide gate 8, and the base end portions thereof are attached to either the left or right mounting rods. 7, a round bar 12 (see FIG. 6) that is upright with respect to the transport surface of the transport conveyor 1 is mounted at the tip.
[0019]
Further, the direction regulation guide arms 10 are arranged so as to alternately protrude from the left and right width end portions of the conveyor 1 to the center side on the downstream side of the above-described direction change guide arms 9 in the same manner as the direction change guide arms 9. The base end portion is attached to either the left or right mounting rod 7, and the front end portion forms a rising surface along the feeding direction of the transfer conveyor 1, and the front and rear end portions of the rising surface are transferred. A flat plate 13 (see FIG. 7) bent to the opposite center side of the conveyor 1 is mounted.
[0020]
The details of the attachment positions of the proximal end portion of the gate arm 11, the proximal end portion of the direction changing guide arm 9, the proximal end portion of the direction regulating guide arm 10, and the left and right attachment rods 7 described above are shown in FIG. In any of these cases, the sleeve members 14 and 15 that cross each other at right angles and are fixed in two upper and lower stages, and the circumferential direction of the sleeve members 14 and 15 are appropriately determined. The mutual attachment is performed by the position adjusting means 18 comprising lock screws 16 and 17 screwed in the radial direction at the positions.
[0021]
That is, the upper sleeve member 14 is slidably fitted on the mounting rod 7 and the lock screw 16 is tightened firmly at an appropriate position to define the position in the feed direction of the conveyor 1 and the lower sleeve member. 15, the base end of the gate arm 11, the base end of the direction changing guide arm 9, or the base end of the direction restricting guide arm 10 is slidably inserted, and the lock screw 17 is firmly tightened at an appropriate position. The overhanging position in the width direction of the conveyor 1 is defined by inserting.
[0022]
In addition, as for the interval between the front ends at the most downstream position of the left and right guide gates 8 and the interval between the direction change guide arm 9 and the direction restricting guide arm 10 arranged in a zigzag shape, the viewpoint of preventing clogging of the small parts 4 is achieved. Therefore, it is secured larger than the maximum dimension of the accessory part 4.
[0023]
Furthermore, in the example illustrated here, a parts collection device 5 that collects the small parts 4 is mounted on the work carriage 2 that is the base end side of the transport conveyor 1. As will be described later, the small component 4 that has been corrected to the correct posture and fed from the base end side of the conveyor 1 can be recovered by inserting a skewer bar 19 into the hole 4a of the small component 4.
[0024]
Here, the skewer bar 19 rises obliquely upward from a lower position slightly away from the base end of the transport conveyor 1 and is just inserted into the hole 4a of the accessory component 4 just before dropping from the base end of the transport conveyor 1. In addition, the same skewer bar 19 is provided at a position where the directions are changed by about 90 ° with respect to each other.
[0025]
The pair of skewers 19 are mounted on a swivel base 21 that is rotated about 90 ° by the expansion and contraction of the air cylinder 20, and a photoelectric tube 22 (see FIG. 2), the number of small parts 4 falling from the base end of the conveyor 1 is counted, and when the number reaches a predetermined number, the air cylinder 20 is driven by the control device 23 and the skewer 19 is moved to another skewer 19 And the rotating lamp 24 is lit to notify the operator.
[0026]
Thus, according to the accessory part aligning apparatus as described above, the accessory part 4 that has been transported on the transport conveyor 1 is guided by the guide gate 8 and brought close to the center in the width direction of the transport conveyor 1. Next, each small component 4 is conveyed while interfering with each of the direction change guide arms 9 protruding alternately from the left and right width end portions of the conveyor 1 to the center side, and the front end side of each small component part 4 is conveyed. What is not directed to the feed direction of the conveyor 1 is gradually changed in direction so that the front end side thereof is directed to the feed direction of the conveyor 1 (see FIG. 1).
[0027]
That is, since the rear end side of the accessory part 4 is wider than the front end side thereof, it easily interferes with the round bar 12 at the tip of each direction changing guide arm 9, and when it interferes with the round bar 12. As a result, the posture of the accessory part 4 is gradually changed to the correct posture with the front end side facing the feed direction of the transport conveyor 1 as a result of the opposite side flowing in the feed direction of the transport conveyor 1 with the interference position as a fulcrum. To go.
[0028]
Here, the fact that the tip of the direction changing guide arm 9 is a round bar 12 that stands upright with respect to the conveying surface means that the direction of the small part 4 is changed using the interference position when it interferes with the small part 4 as a fulcrum. It is very effective in enhancing sex.
[0029]
Then, each accessory part 4 whose direction is roughly changed to a correct posture by these direction change guide arms 9 is conveyed while interfering with each of the next direction restriction guide arms 10, and the distal end portion of each direction restriction guide arm 10. The flat plate 13 further adjusts the posture so as to follow the upright surface of the flat plate 13, and finally all the small parts 4 are corrected and aligned in the correct posture with the front end side facing the feed direction of the conveyor 1. The
[0030]
Here, the distal end portion of the direction regulating guide arm 10 forms a flat plate 13 which forms an upstanding surface along the feeding direction of the transport conveyor 1 and warps the front and rear end portions of the upright surface toward the anti-center side of the transport conveyor 1. This is very effective in smoothly adjusting the posture of each small component 4 that has already been turned into a roughly correct posture.
[0031]
Then, the small parts 4 that are corrected to the correct posture and are sent out from the base end side of the conveyor 1 are hung in a skewered manner by the skewer bar 19 of the above-described parts collecting device 5 and are recovered satisfactorily. When the collected number reaches the predetermined number, the air cylinder 20 switches to another skewer bar 19 and the collection is continued. On the other hand, an operator who notices the turning on of the rotating lamp 24 causes the predetermined number of small parts 4 to be skewered. It is removed from the bar 19 and loaded into a predetermined storage container.
[0032]
Therefore, according to the above-described embodiment, a large number of small component parts 4 can be aligned in the same direction while being conveyed by the conveyer 1, and the small component parts 4 aligned in the same direction can be used without any trouble by the component collecting device 5. The work is completed simply by collecting and loading the small parts 4 that have reached the predetermined number into the predetermined storage container. Therefore, the work time and labor required to load the small parts 4 into the predetermined storage container are significantly reduced. And the burden on the operator can be greatly reduced.
[0033]
Particularly in this embodiment, each of the guide gate 8, the direction changing guide arm 9, and the direction regulating guide arm 10 is moved in the feed direction and the width direction of the transport conveyor 1 by the position adjusting means 18 described above with reference to FIG. The left and right guide gates 8 can be arranged slightly shifted in the feed direction of the conveyor 1 and the distance between the left and right guide gates 8 can be adjusted. The projecting position of the round bar 12 and the flat plate 13 at the tip of the direction changing guide arm 9 and the direction regulating guide arm 10 and the arrangement position in the feed direction of the conveyor 1 can be arbitrarily adjusted. The optimal arrangement condition according to the shape, size, etc. of the small parts 4 is obtained by repeating the trial and error by flowing the small parts 4 on a trial basis while adjusting appropriately It is possible to find easily.
[0034]
For example, if the left and right guide gates 8 are arranged slightly shifted in the feed direction of the conveyor 1, the accessory parts 4 are reduced while narrowing the gap between the left and right guide gates 8 to bring the accessory parts 4 close to the center in the width direction of the conveyor 1. This is effective in avoiding the clogging of the direction change guide arm 9 and the direction restricting guide arm 10, and the distance between the zigzag-shaped arrangements of the direction change guide arm 9 and the direction restriction guide arm 10 is relatively high on the upstream side in the feed direction of the conveyor 1. Since the present inventors have already obtained the knowledge that it is effective to efficiently correct the posture of the accessory part 4 if it is made larger and gradually narrowed toward the downstream side. It is practically important to appropriately determine the adjustment of the arrangement conditions according to the shape, size, etc. of the accessory part 4.
[0035]
The accessory parts aligning device of the present invention is not limited to the above-described embodiments. The combined use of the parts collecting device is an item that can be arbitrarily selected, and the shape of the accessory parts is shown in the example shown in the drawing. Of course, it is not limited, it may be a fixed installation type that is not mounted on a work carriage, and various changes can be made without departing from the scope of the present invention.
[0036]

According to the accessory component aligning apparatus of the present invention described above, various excellent effects as described below can be obtained.
[0037]
(I) According to the invention described in claim 1 of the present invention, since a large number of small parts can be conveyed and aligned in the same direction, the small parts aligned in the same direction are collected and counted. However, the work can be completed simply by loading it into the predetermined storage container, and this significantly reduces the work time and labor required to load small parts into the predetermined storage container, greatly reducing the burden on the operator. be able to.
[0038]
(II) According to the invention described in claim 2 of the present invention, the left and right guide gates can be arranged slightly shifted in the feed direction of the conveyor, and the mutual interval between the left and right guide gates can be adjusted. In addition, the protruding position of the round bar and the flat plate at the tip of the direction change guide arm and the direction regulation guide arm and the arrangement position in the feed direction of the conveyor can be arbitrarily adjusted. It is possible to easily find the optimum arrangement condition according to the shape and size of the small parts by repeating the trial and error by flowing the small parts on a trial basis while adjusting.
