とんどが磁性体であることを利用したもので、その一例
を第２図及び第３図で説明すると次の通りである。Further, the magnet feeder utilizes the fact that most of the lead wires 2 of the shaft-shaped component 3 are made of magnetic material, and an example thereof will be explained below with reference to FIGS. 2 and 3.

第２図及び第３図において、４及び５は板厚方向に着磁
された２枚の矩形の磁石板、６は２枚の磁石板４，５の
異なる極性面を部品送り方向に幅狭にして対向させて保
持する底板である。In Figures 2 and 3, 4 and 5 are two rectangular magnet plates magnetized in the plate thickness direction, and 6 is a narrow magnet plate with different polarity surfaces of the two magnet plates 4 and 5 in the component feeding direction. It is a bottom plate that is held facing each other.

この各磁石板４，５の幅狭側端部４ｍ、５ｍの間隔は軸
状部品３の全長１と同一か若干太き目に設定しである。The spacing between the narrow end portions 4m and 5m of each of the magnet plates 4 and 5 is set to be equal to or slightly thicker than the overall length 1 of the shaft-shaped component 3.

また７は磁石板４，５の幅広側端部４ｎ。５ｎの間に任

ンベアである。Further, reference numeral 7 designates the wide end portions 4n of the magnet plates 4 and 5. a supply chute for supplying the shaft-shaped part 3 in any state during 5n; 8 a rotating drum disposed at an intermediate position between the ends 4m and 5m; 9 disposed on both sides of the upper part of the rotating drum 8; This is a take-out conveyor.

回転ドラム８は外周上に等間隔で複数個の点磁石１０を
埋設したもので、図面矢印方向に適宜連続回転する。The rotating drum 8 has a plurality of dot magnets 10 embedded at equal intervals on its outer periphery, and continuously rotates as appropriate in the direction of the arrow in the figure.

上記装置は軸状部品３を次のように整列して、１個ずつ
コンベア９へ切出す。The above-mentioned apparatus arranges the shaft-like parts 3 as follows and cuts them out one by one onto the conveyor 9.

即ち、供給シュート７から複数の軸状部品３を各磁石板
４，５の間隔が広に一端部４ｎｔ ５ｎ間へ移送すると

４に、他方が磁石板５に磁気吸引されて、軸状部品３は
軸方向が磁石板４，５間の磁界方向に並び、自動的に整
列される。That is, when a plurality of shaft-shaped parts 3 are transferred from the supply chute 7 to one end portion 4nt to 5n of each magnet plate 4, 5 with a wide interval, one of the two lead wires 2, 2 of each shaft-shaped part 3 is transferred. The shaft-like parts 3 are magnetically attracted by the magnet plate 4 and the other by the magnet plate 5, so that the shaft-like parts 3 are automatically aligned so that their axial directions are aligned in the direction of the magnetic field between the magnet plates 4 and 5.

その軸状部品３は磁石板４，５の間で浮いた状態で整列
する。The shaft-shaped parts 3 are aligned in a floating state between the magnet plates 4 and 5.

ここで各磁石板４，５間の磁界強度は一端部４ｎ、５ｎ
から他の端部４ｍｖ５ｍに向う程に強くなっているので
、端部４ｎ、５ｎ間に整列した軸状部品３は整列した状
態でより磁界の強い方向に移動、つまり磁石板４，５の
幅狭な方向へと徐々に移動していく。Here, the magnetic field strength between each magnet plate 4, 5 is at one end 4n, 5n
Since the strength increases as the magnetic field increases from 4 m to 5 m toward the other end, the shaft-shaped parts 3 aligned between the ends 4n and 5n move in the direction of the stronger magnetic field while remaining aligned, that is, the width of the magnetic plates 4 and 5 increases. Gradually move in a narrow direction.

そして、軸状部品３が回転している回転ドラム８のとこ

ム８と共に上方へと移動して磁石板４，５の間から離れ
、コンベア９上へと切出されていく。When the shaft-shaped part 3 moves to the rotating drum 8, the lead wires 2, 2 are attracted to the point magnet 10 of the rotating drum 8, and the shaft-shaped parts 3 are moved one by one along with the rotating drum 8. It moves upward, separates from between the magnet plates 4 and 5, and is cut out onto the conveyor 9.

コンベア９は整列した軸状部品３を１個ずつ捺印機等へ
搬送する。The conveyor 9 conveys the aligned shaft-like parts 3 one by one to a stamping machine or the like.

軸状部品３を空中で整列して搬送するため、部品同士の
接触による事故が少なくて動作が比較的スムーズに行え
、而も部品の損傷が少ないといったメリットを有する。Since the alignment and conveyance device using such a magnetic feeder aligns and conveys the shaft-shaped parts 3 in the air, there are fewer accidents caused by contact between parts, and the operation is relatively smooth, with less damage to the parts. It has the following advantages.

ところで上記装置において回転ドラム８で軸状部品３を
１個ずつ確実に切出すためには各磁石板４，５の間にあ
る部品ストック量を少なく制限しておく必要があった。By the way, in order to reliably cut out the shaft-shaped parts 3 one by one using the rotating drum 8 in the above-mentioned apparatus, it was necessary to limit the amount of parts stocked between the respective magnet plates 4 and 5 to a small amount.

つまり、部品ストック量を多くすると一度に多数の軸状
部品３が回転ドラム８に向うため、回転ドラム８が軸状
部品３を２個同時に切出したりすることがある。In other words, when the amount of parts stock is increased, a large number of shaft-shaped components 3 are directed toward the rotating drum 8 at one time, so that the rotating drum 8 may cut out two shaft-shaped components 3 at the same time.

また各磁石板４，５の対向角度を小さくして磁石板４，
５の部品送り方向の長さを長くすることにより、両者間

では部品送りがスムーズにできす、回転ドラム８を移動
させたりする必要があって好ましくない。In addition, the opposing angle of each magnet plate 4, 5 is made smaller so that the magnet plate 4,
It may be possible to increase the amount of parts stocked between the two by increasing the length in the part feeding direction of 5, but this would not allow parts to be fed smoothly and would require moving the rotating drum 8. I don't like it.

そこで現状は部品ストック量を少なくして動作の安定化
を図っているが、部品ストック量が少ないと部品供給を
少量ずつ頻繁に行う必要があり、改善策が要望されてい
た。Therefore, current efforts are being made to stabilize operation by reducing the amount of parts in stock, but when the amount of parts in stock is small, it is necessary to frequently supply parts in small quantities, and improvements have been desired.

本考案はかかる従来の問題点に鑑みてなされたもので、

送り方向に幅狭に対向させる。What is different is the following two magnet plates 11 and 12. For example, each is formed into an L-shaped integral piece, and the lower portions 11a and 12a extending in the horizontal direction are the same as the magnet plates 4.5 above. narrowly facing the part feeding direction.

b and 12b are opposed to each other, and the supply chute 7 is disposed above between the upper parts 11b and 12b.

尚、各磁石板１１．１２は板厚方向に着磁され、各々の
対向面は極性を異にする。Note that each magnet plate 11, 12 is magnetized in the thickness direction, and each opposing surface has a different polarity.

2.

つまり、磁石板１１，１２の上部１１ａ、１２ａは対向
するから、空間Ｆ１での軸状部品３は磁気による送り作
用は受けずに自重のみで落下しようとする。That is, since the upper portions 11a and 12a of the magnet plates 11 and 12 face each other, the shaft-shaped component 3 in the space F1 tends to fall only by its own weight without being subjected to magnetic feeding action.

例えば空間Ｆ１に軸状部品３が飽和するまでに大量に供
給されたとすると、その大部分は空間Ｆ１内に停留して
下のものから順次に空間Ｆ２に落下していく。For example, if a large amount of shaft-shaped parts 3 are supplied to the space F1 until the shaft-like parts 3 are saturated, most of them stay in the space F1 and fall into the space F2 one after another starting from the bottom.

すると空間Ｆ２に入った軸状部品３は磁石板下部１１ａ
