The top cylindrical roller w is stopped by a stopper 2a in front of the following cylindrical roller w to be dropped, and also the dragged rotations of the following cylindrical rollers w are stopped in order. A chute port 4a is shifted from the position just above the central axis c of the central shaft 1 in the rotational direction of the central shaft. Nearly half of the definite number of the cylindrical rollers are supplied into the annular space 3 at the time to start the rotation of the central shaft 1. As a result, the definite number of the cylindrical rollers are efficiently placed in an annular row. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

この発明は、ニードル軸受、ピニオンギヤ等の総ころ入れ軸受機構の組立に際し、定数の円筒ころを予め円環状に整列させた状態で内外の軌道面間に挿入するために利用される総ころ入れ軸受機構の組立装置に関する。   The present invention relates to a full-roller bearing used to insert a constant number of cylindrical rollers between inner and outer raceways in a state where they are aligned in advance in an annular shape when assembling a full-roller bearing mechanism such as a needle bearing and a pinion gear. The present invention relates to a mechanism assembly apparatus.

この種の総ころ軸受機構の組立装置として、中心軸とハウジングとで円環状空間を形成し、その円環状空間に供給された円筒ころを前記中心軸の回転で軸回りに連れ回すことにより定数の円筒ころを円環状に整列させ、その定数の円筒ころを前記円環状空間と軸方向に連通するころ挿入空間に対して一斉挿入するプッシャーを設けたものが利用されている(例えば、特許文献1参照)。   As an assembly device for this kind of full roller bearing mechanism, an annular space is formed by a central shaft and a housing, and a cylindrical roller supplied to the annular space is rotated around the axis by rotation of the central shaft, thereby generating a constant number. A cylindrical roller is arranged in an annular shape, and a pusher is provided for simultaneously inserting the constant number of cylindrical rollers into a roller insertion space communicating with the annular space in the axial direction (for example, Patent Document 1). reference).

中心軸は、縦軸になっている。円環状空間の下方にころ挿入空間が形成され、定数の円筒ころを整列させ終えるまでの間、円環状空間ところ挿入空間の間は、シャッターで閉塞されている。円筒ころは、概ね縦向きでシュート口から1つずつ漏斗状のガイドに落下させられ、円環状空間に導かれるようになっている。円環状空間の径方向隙間は、円筒ころの外径より僅かに大きくなっている。このため、円環状空間に落ち込んだ円筒ころは、殆ど傾かず、中心軸に連れ回される。順次に供給される後続の円筒ころは、円環状空間において既に連れ回されている円筒ころ間の間隙に落ち込み、やがて定数の円筒ころが円環状に整列させられる。   The central axis is the vertical axis. A roller insertion space is formed below the annular space, and the space between the annular space and the insertion space is closed by a shutter until the constant number of cylindrical rollers are aligned. The cylindrical rollers are generally dropped vertically and are dropped one by one from the chute into a funnel-shaped guide and guided to the annular space. The radial clearance in the annular space is slightly larger than the outer diameter of the cylindrical roller. For this reason, the cylindrical roller that has fallen into the annular space hardly tilts and is rotated around the central axis. Subsequent cylindrical rollers that are sequentially supplied fall into the gaps between the already-rolled cylindrical rollers in the annular space, and the constant number of cylindrical rollers is eventually aligned in an annular shape.

特開平5−329721号公報Japanese Patent Laid-Open No. 5-329721

しかしながら、前掲の特許文献1に開示されたように中心軸が縦軸の総ころ軸受機構の組立装置では、円筒ころを円環状空間に導入する漏斗状のガイドがあり、ハウジングが大きくなってしまう。また、各円筒ころは、定数に近づく程、円環状空間に入り難くなる問題がある。
また、上下に連通する円環状空間ところ挿入空間の間を開閉するシャッターが必要であり、装置が複雑な点で改良の余地がある。
However, as disclosed in the above-mentioned Patent Document 1, in the assembly apparatus of the full roller bearing mechanism having the central axis as the vertical axis, there is a funnel-shaped guide for introducing the cylindrical roller into the annular space, and the housing becomes large. . Moreover, each cylindrical roller has a problem that it becomes difficult to enter the annular space as it approaches a constant.
In addition, a shutter that opens and closes between the annular space and the insertion space communicating with each other in the vertical direction is necessary, and there is room for improvement in that the apparatus is complicated.

上述の事情に鑑み、この発明は、中心軸とハウジングとで円環状空間を形成し、その円環状空間に供給された円筒ころを前記中心軸の回転で軸回りに連れ回す総ころ軸受機構の組立装置において、装置を単純かつコンパクトにしつつ、定数の円筒ころを効率よく整列させることにある。   In view of the circumstances described above, the present invention provides an assembly of a full roller bearing mechanism in which an annular space is formed by a central shaft and a housing, and a cylindrical roller supplied to the annular space is rotated around the shaft by rotation of the central shaft. In the apparatus, a simple and compact apparatus is used, and a constant number of cylindrical rollers are efficiently aligned.

上記の課題を達成するため、この発明は、中心軸とハウジングとで円環状空間を形成し、その円環状空間に供給された円筒ころを前記中心軸の回転で軸回りに連れ回すことにより定数の円筒ころを円環状に整列させるようにした総ころ軸受機構の組立装置において、前記中心軸を水平軸とし、前記ハウジングに、前記中心軸の上方から前記円筒ころを軸方向に平行な向きで落下させるシュート口を開放させ、先に落下した円筒ころが前記シュート口の下方から軸回転方向に移動すると後続の円筒ころが前記中心軸に落下するようにし、連れ回される先頭の円筒ころを前記シュート口から落下する後続の円筒ころの手前で停止させるストッパを備えたことを特徴とする構成を採用したものである。   In order to achieve the above object, the present invention forms an annular space with a central shaft and a housing, and rotates a cylindrical roller supplied to the annular space around the axis by the rotation of the central shaft. In an assembly apparatus for a full roller bearing mechanism in which cylindrical rollers are arranged in an annular shape, the central axis is a horizontal axis, and the cylindrical roller is dropped onto the housing from above the central axis in a direction parallel to the axial direction. The chute opening is opened, and when the previously dropped cylindrical roller moves in the axial rotation direction from below the chute opening, the subsequent cylindrical roller is dropped to the central axis, and the leading cylindrical roller to be rotated is A configuration is provided in which a stopper is provided that stops before the subsequent cylindrical roller falling from the chute opening.

具体的には、中心軸を水平軸としたため、円環状空間も水平になり、円筒ころが水平軸回りに連れ回されるようになる。このため、円環状空間を閉じるシャッターが不要になる。
また、水平に向いた中心軸と円環状空間にすれば、前記ハウジングに、前記中心軸の上方から前記円筒ころを軸方向に平行な向きで落下させるシュート口を開放させることが可能になる。これにより、シュート口から落下した円筒ころは、概ね円筒ころの外径寸法を落下すると、その転動面が軸方向に平行な向きで前記中心軸の外周に接触し、速やかに中心軸で連れ回されるようになる。すなわち、ハウジングに漏斗状のガイドを設ける必要がない。
ここで、先に落下した円筒ころが前記シュート口の下方から軸回転方向に移動すると後続の円筒ころが中心軸に落下するため、後続の円筒ころが先の円筒ころの直後に落下し、大きく離間することなく連れ回される。
連れ回される先頭の円筒ころは、落下する後続の円筒ころの手前でストッパにより停止させられ、その場で自転する。後続の円筒ころも先の円筒ころとの接触で順次に連れ回りを停止させられ、その場で自転する。このため、定数の円筒ころは、効率よく円環状に整列させられる。
Specifically, since the central axis is a horizontal axis, the annular space is also horizontal, and the cylindrical roller is rotated around the horizontal axis. For this reason, a shutter for closing the annular space becomes unnecessary.
Further, if the center axis and the annular space that are horizontally oriented are used, it is possible to open a chute opening that allows the cylindrical roller to fall in a direction parallel to the axial direction from above the center axis. As a result, when the cylindrical roller dropped from the chute opening generally falls outside the outer diameter of the cylindrical roller, its rolling surface comes into contact with the outer periphery of the central shaft in a direction parallel to the axial direction, and quickly follows the central shaft. It will be turned. That is, it is not necessary to provide a funnel-shaped guide in the housing.
Here, when the previously dropped cylindrical roller moves in the axial rotation direction from below the chute opening, the subsequent cylindrical roller falls to the central axis, so the subsequent cylindrical roller falls immediately after the previous cylindrical roller, It is carried around without leaving.
The leading cylindrical roller to be rotated is stopped by a stopper in front of the falling subsequent cylindrical roller and rotates on the spot. The subsequent cylindrical rollers are also sequentially stopped by contact with the previous cylindrical roller, and rotate on the spot. For this reason, the constant cylindrical rollers are efficiently aligned in an annular shape.

上記構成においては、前記シュート口から落下した円筒ころが前記中心軸の中心線直上から軸回転方向側に外れた位置に接触するようにし、前記中心軸が停止する状態で前記シュート口に先の円筒ころが停止するまで後続の円筒ころが供給されるようにした構成を採用することが好ましい。
中心軸が停止する状態でシュート口から落下した円筒ころは、軸回転方向側に転がり落ちる。後続の円筒ころは、同様に転がって先の円筒ころに接触することになる。このため、前記中心軸が停止する状態で前記シュート口に先の円筒ころが停止するまで後続の円筒ころが供給されるように構成することができる。この構成の採用により、シュート口の下方から円環状空間の底を過ぎた範囲に亘って隣り合う円筒ころ同士が接触し、互いに周方向に押し合った状態で停止する。
ここで、円環状空間の径方向寸法が円筒ころの外径より僅かに大きいため、円筒ころは、円環状空間で僅かに傾くことができる。円筒ころは、傾き状態で中心軸側からの摩擦を受けて回転すると、中心軸の回りを螺旋様に回ろうとする。すなわち、連れ回される円筒ころは、軸方向に移動しようとする。この構成によれば、上述のように、隣り合う円筒ころ同士が接触し、互いに周方向に押し合った状態となり、その結果、各円筒ころの傾きが抑制される条件を予め作り出した状態で中心軸の回転を開始させることが可能になる。したがって、この構成によれば、整列中に円筒ころが円環状空間から抜け出ることを防止することができる。
また、この構成によれば、先頭の円筒ころが円環状空間の底を過ぎた位置に停止するため、その先走りが防止される。先走りした先頭の円筒ころは、傾いて螺旋様に回り易くなるため、その防止は円滑な整列に有利である。
また、この構成によれば、定数の円筒ころの一部が予め円環状空間に整列された状態で中心軸の回転が開始されるため、中心軸の回転時間が短縮される。その結果、省エネルギ化を図ることができる。
In the above-described configuration, the cylindrical roller that has dropped from the chute is in contact with a position that is off the axial rotation direction from directly above the central line of the central axis, and the chute is in front of the chute while the central axis is stopped. It is preferable to adopt a configuration in which subsequent cylindrical rollers are supplied until the cylindrical rollers are stopped.
The cylindrical roller that has fallen from the chute while the central axis is stopped rolls down in the axial direction. The succeeding cylindrical roller rolls in the same manner and comes into contact with the previous cylindrical roller. For this reason, it can comprise so that the following cylindrical roller may be supplied to the said chute | shoot opening until the previous cylindrical roller stops in the state which the said center axis | shaft stops. By adopting this configuration, adjacent cylindrical rollers come into contact with each other over a range past the bottom of the annular space from below the chute opening, and stop in a state where they are pressed against each other in the circumferential direction.
Here, since the radial dimension of the annular space is slightly larger than the outer diameter of the cylindrical roller, the cylindrical roller can be slightly inclined in the annular space. When the cylindrical roller rotates in response to friction from the central axis side in an inclined state, the cylindrical roller tends to rotate in a spiral manner around the central axis. That is, the cylindrical roller that is rotated tends to move in the axial direction. According to this configuration, as described above, adjacent cylindrical rollers are in contact with each other and pressed against each other in the circumferential direction, and as a result, the condition in which the inclination of each cylindrical roller is suppressed is created in advance. It becomes possible to start the rotation of the shaft. Therefore, according to this configuration, it is possible to prevent the cylindrical rollers from coming out of the annular space during alignment.
In addition, according to this configuration, the leading cylindrical roller stops at a position past the bottom of the annular space, so that the preceding run is prevented. Since the leading cylindrical roller that has run ahead is inclined and easily turns like a spiral, prevention thereof is advantageous for smooth alignment.
Further, according to this configuration, since the rotation of the central axis is started in a state where a part of the constant cylindrical rollers are previously aligned in the annular space, the rotation time of the central axis is shortened. As a result, energy saving can be achieved.

また、上記構成においては、外側の軌道面を有する外方部材の内方に前記中心軸を前進させてころ挿入空間を形成し、そのころ挿入空間に前記定数の円筒ころを一斉挿入するプッシャーを設け、一斉挿入された円筒ころの後退が前記プッシャーにより規制された状態で、前記中心軸を後退させると共に、内側の軌道面を有する内方部材を挿入するようにした構成を採用することが好ましい。
外側の軌道面を有する外方部材の内方に前記中心軸を前進させてころ挿入空間を形成する構成により、円環状空間ところ挿入空間が軸方向に平行かつ水平に連通することになる。そのころ挿入空間には、プッシャーにより前記定数の円筒ころが一斉挿入される。
一斉挿入された円筒ころの後退が前記プッシャーにより規制された状態で、前記中心軸を後退させると共に、内側の軌道面を有する内方部材を挿入するため、一斉挿入された円筒ころが中心軸の後退に引き摺られてころ挿入空間から抜け落ちることを防止することができる。
Further, in the above configuration, a roller insertion space is formed by advancing the central shaft inward of an outer member having an outer raceway surface, and a pusher for simultaneously inserting the constant number of cylindrical rollers into the roller insertion space. It is preferable to adopt a configuration in which an inner member having an inner raceway surface is inserted while the central shaft is retracted in a state where the retraction of the cylindrical rollers that are simultaneously inserted is regulated by the pusher. .
With the configuration in which the central shaft is advanced inward of the outer member having the outer raceway surface to form the roller insertion space, the insertion space communicates horizontally and horizontally in the axial direction. The constant number of cylindrical rollers are simultaneously inserted into the roller insertion space by a pusher.
In the state where the retraction of the simultaneously inserted cylindrical rollers is regulated by the pusher, the central shaft is retracted and the inner member having the inner raceway surface is inserted. It can be prevented that the roller is pulled back and falls out of the roller insertion space.

上述のように、この発明は、中心軸とハウジングとで円環状空間を形成し、その円環状空間に供給された円筒ころを前記中心軸の回転で軸回りに連れ回す総ころ軸受機構の組立装置において、上述の特徴的構成を採用することにより、円環状空間を閉じるシャッターや漏斗状のガイドが不要になり、装置を単純かつコンパクトにしつつ、定数の円筒ころが効率よく円環状に整列させることができる。   As described above, the present invention forms an annular space with a central shaft and a housing, and an assembly device for a full roller bearing mechanism in which a cylindrical roller supplied to the annular space is rotated around the shaft by the rotation of the central shaft. By adopting the above-mentioned characteristic configuration, a shutter or funnel-shaped guide for closing the annular space becomes unnecessary, and a constant number of cylindrical rollers can be efficiently aligned in an annular shape while making the device simple and compact. Can do.

この発明の第1実施形態に係る総ころ軸受機構の組立装置を添付図面に基づいて説明する。
図1に示すように、第1実施形態に係る総ころ軸受機構の組立装置は、中心軸1とハウジング2とで円環状空間3を形成し、その円環状空間3に供給された円筒ころw、w、w・・・を中心軸1の回転で軸回りに連れ回すことにより定数の円筒ころを円環状に整列させるようにしたものである。
An assembly apparatus for a full roller bearing mechanism according to a first embodiment of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1, the assembly apparatus for a full roller bearing mechanism according to the first embodiment forms an annular space 3 with a central shaft 1 and a housing 2, and cylindrical rollers w supplied to the annular space 3. , W,... Are rotated around the axis by the rotation of the central shaft 1 so that constant cylindrical rollers are aligned in an annular shape.

この第1実施形態に係る円筒ころwは、ニードルからなる。この第1実施形態に係る総ころ軸受機構の組立装置は、総ころ入れのニードル軸受の組立用に構成されている。   The cylindrical roller w according to the first embodiment is a needle. The assembly apparatus for a full roller bearing mechanism according to the first embodiment is configured for assembling a needle bearing with a full roller holder.

上記中心軸1は水平軸とされている。上記ハウジング2は、固定側に嵌合支持されたスリーブで構成されている。中心軸1の先端部外周が、円筒面となっており、ハウジング2の円筒状内壁と同心に挿通されている。これにより、円環状空間3が水平に形成される。   The central axis 1 is a horizontal axis. The housing 2 is composed of a sleeve fitted and supported on the fixed side. The outer periphery of the tip of the central shaft 1 is a cylindrical surface, and is inserted concentrically with the cylindrical inner wall of the housing 2. Thereby, the annular space 3 is formed horizontally.

上記中心軸1は、軸方向に進退可能に設けられている。中心軸1が後退位置にある状態で上記円環状空間3が形成されるようになっている。   The central shaft 1 is provided so as to advance and retract in the axial direction. The annular space 3 is formed with the central shaft 1 in the retracted position.

上記ハウジング2には、中心軸1の上方から1つの円筒ころwを軸方向に平行な向きで落下させるシュート口4aが開放させられている。シュート口4aは、重力シュート4の出口となっている。重力シュート4は、少なくとも定数の円筒ころwを各円筒ころwが軸方向に平行な向きに揃った状態で一列に収納可能なものが利用されている。なお、重力シュート4の供給口4bは、図示省略のフィーダに接続されている。   The housing 2 is opened with a chute 4a for dropping one cylindrical roller w from above the central shaft 1 in a direction parallel to the axial direction. The chute 4a is an outlet of the gravity chute 4. As the gravity chute 4, one that can store at least a fixed number of cylindrical rollers w in a row with the cylindrical rollers w aligned in a direction parallel to the axial direction is used. The supply port 4b of the gravity chute 4 is connected to a feeder (not shown).

先に落下した円筒ころwがシュート口4aの下方から軸回転方向に移動すると、重力シュート4に予め収納された後続の円筒ころwがシュート口4aから中心軸1に落下するようになっている。より詳細には、先に落下した円筒ころwが軸方向回転側に移動するに連れて後続の円筒ころwが徐々に落ち始め、先に落下した円筒ころwが完全にシュート口4aの下方から外れると略同時に後続の円筒ころwが中心軸1に接触するようになっている。   When the previously dropped cylindrical roller w moves in the axial direction from below the chute 4a, the subsequent cylindrical roller w stored in advance in the gravity chute 4 falls from the chute 4a onto the central shaft 1. . More specifically, as the previously dropped cylindrical roller w moves to the axial rotation side, the subsequent cylindrical roller w begins to gradually fall, and the previously dropped cylindrical roller w completely disappears from below the chute 4a. Subsequent cylindrical rollers w come into contact with the central shaft 1 substantially at the same time.

なお、重力シュート4を用いたものに限定されず、先の円筒ころwがシュート口4aの下方から移動するまでに後続の円筒ころwがシュート口4aに準備される限り、適宜の供給装置をシュート口4aに接続することができる。   In addition, it is not limited to the thing using the gravity chute 4, As long as the subsequent cylindrical roller w is prepared in the chute 4a until the previous cylindrical roller w moves from the lower side of the chute 4a, an appropriate supply device is used. It can be connected to the chute 4a.

この第1実施形態においては、上記のシュート口4aが中心軸1の中心線cの直上から軸回転方向側にオフセットされた位置にある。これにより、シュート口4aから落下した円筒ころwの転動面は、前記の中心線cの直上から軸回転方向側に水平距離lだけ外れた位置の外周上に接触するようになっている。このため、中心軸1が回転を停止している状態で落下した円筒ころwは、自然と軸回転方向側に転がり落ちる。   In the first embodiment, the chute 4a is located at a position offset from the position directly above the center line c of the central shaft 1 toward the axial direction. As a result, the rolling surface of the cylindrical roller w dropped from the chute 4a comes into contact with the outer periphery at a position deviated from the position directly above the center line c by the horizontal distance l in the axial direction. For this reason, the cylindrical roller w that has fallen in a state where the central shaft 1 has stopped rotating naturally rolls down in the axial rotation direction.

上記円環状空間3の径方向寸法は、円筒ころwの外径寸法精度を見越してこれよりも僅かに大きく設けられている。このため、円筒ころwは、円環状空間3において中心軸1の回転により軸回りに円滑に連れ回される。   The radial dimension of the annular space 3 is slightly larger than this in anticipation of the accuracy of the outer diameter of the cylindrical roller w. For this reason, the cylindrical roller w is smoothly rotated around the axis by the rotation of the central shaft 1 in the annular space 3.

上記ハウジング2は、連れ回される先頭の円筒ころwをシュート口4aから落下する後続の円筒ころwの手前で停止させるストッパ2aを備えている。   The housing 2 is provided with a stopper 2a for stopping the leading cylindrical roller w to be rotated before the subsequent cylindrical roller w falling from the chute 4a.

ストッパ2aは、シュート口4aの直前で円環状空間3に入り込んで楔空間を形成している。   The stopper 2a enters the annular space 3 just before the chute 4a to form a wedge space.

先頭の円筒ころwは、ストッパ2aに受けられることでその連れ回りをシュート口4aの直前で停止させられ、その場で自転する。先頭の円筒ころwの連れ回りが停止させられると、後続の円筒ころwが先の円筒ころwに接触することで連れ回りを順次に停止させられる。このため、定数の円筒ころw、w、w・・・は、効率よく円環状に整列させられる。なお、ストッパ2aは、円環状空間3に定数の円筒ころw、w、w・・・を円環状に整列させることができる限り、その配置、構成等を任意に変更することができる。   The leading cylindrical roller w is stopped by the stopper 2a just before the chute 4a and is rotated on the spot. When the leading cylindrical roller w is stopped, the subsequent cylindrical roller w comes into contact with the preceding cylindrical roller w to sequentially stop the accompanying rotation. Therefore, the constant cylindrical rollers w, w, w... Are efficiently aligned in an annular shape. The stopper 2a can be arbitrarily changed in its arrangement, configuration, etc., as long as the constant cylindrical rollers w, w, w... Can be aligned in the annular space 3 in an annular shape.

上記ハウジング2の軸方向前側に、外側の軌道面を有する外方部材5が搬送されるようになっている。この第1実施形態における外方部材5は、外輪からなり、中心軸1の中心線cと同心に、かつその内径がハウジング2の円筒状内壁と概ね隙間なく連続するように配置される。中心軸1が前進位置にある状態で、その先端部外周と外方部材5の内径とにより、円環状空間3と軸方向に平行かつ水平に連通するころ挿入空間が形成されるようになっている。   An outer member 5 having an outer raceway surface is conveyed on the front side in the axial direction of the housing 2. The outer member 5 in the first embodiment is composed of an outer ring, and is arranged so as to be concentric with the center line c of the central shaft 1 and to have an inner diameter that is substantially continuous with the cylindrical inner wall of the housing 2. With the central shaft 1 in the forward position, a roller insertion space communicating with the annular space 3 parallel to the axial direction and in the horizontal direction is formed by the outer periphery of the front end portion and the inner diameter of the outer member 5. Yes.

上記中心軸1と独立に円環状空間3に対して軸方向に進退可能なプッシャー6が設けられている。円環状に整列させられた定数の円筒ころw、w、w・・・は、上記ころ挿入空間に一斉挿入されるようになっている。この第1実施形態では、プッシャー6が円筒状に設けられており、その内方に中心軸1が挿通されている。これにより、装置のコンパクト化が図られている。   A pusher 6 capable of moving forward and backward in the axial direction with respect to the annular space 3 is provided independently of the central shaft 1. A fixed number of cylindrical rollers w, w, w... Aligned in an annular shape are inserted into the roller insertion space all at once. In the first embodiment, the pusher 6 is provided in a cylindrical shape, and the central shaft 1 is inserted through the inside thereof. Thereby, the apparatus is made compact.

搬送された外方部材5の内方には、内側の軌道面を有する内方部材7が中心軸1と反対側から挿入されるようになっている。この第1実施形態における内方部材7は、内輪からなり、その内周に受け治具8の先端部が嵌合されるようになっている。受け治具8は、軸方向に進退可能になっている。受け治具8は、中心軸1の中心線cと同心に、かつ内方部材7の外径が中心軸1の先端部外周と概ね隙間なく連続する状態を保つように前進させられる。その結果、内方部材7が外方部材5の内方に同心に挿入され、両部材5、7の軌道面間に定数の円筒ころが挿入されるようになっている。   An inner member 7 having an inner raceway surface is inserted from the opposite side of the central shaft 1 into the inner side of the conveyed outer member 5. The inner member 7 in the first embodiment is composed of an inner ring, and the front end portion of the receiving jig 8 is fitted to the inner periphery thereof. The receiving jig 8 can advance and retreat in the axial direction. The receiving jig 8 is advanced so as to be concentric with the center line c of the central shaft 1 and to maintain a state in which the outer diameter of the inner member 7 is substantially continuous with the outer periphery of the distal end portion of the central shaft 1. As a result, the inner member 7 is inserted concentrically inside the outer member 5, and a fixed number of cylindrical rollers are inserted between the raceway surfaces of both members 5, 7.

次に、この第1実施形態の動作を述べる。
図1は、動作の一サイクルの初期段階を示している。この初期段階では、中心軸1が、回転を停止した状態で後退位置にあり、円環状空間3が形成される。このとき、プッシャー6は、シュート口4aよりも後方に退避させられており、シュート口4aが円環状空間3に開放される。このシュート口4aが開放したとき、重力シュート4に予め定数以上の円筒ころw、w、w・・・が収納されている。シュート口4aから落下した先頭の円筒ころwは、中心線cの直上から軸回転方向側に水平距離lだけ外れて中心軸1に接触するため、軸回転方向側に転がり落ち、後続の円筒ころwがシュート口4aから順次に落下していく。
Next, the operation of the first embodiment will be described.
FIG. 1 shows the initial stage of one cycle of operation. In this initial stage, the central shaft 1 is in the retracted position with the rotation stopped, and the annular space 3 is formed. At this time, the pusher 6 is retracted rearward from the chute 4a, and the chute 4a is opened to the annular space 3. When this chute opening 4a is opened, cylindrical rollers w, w, w... The leading cylindrical roller w that has fallen from the chute 4a comes off the horizontal distance l from the position directly above the center line c in the axial rotation direction and comes into contact with the central axis 1, so that it rolls down in the axial rotation direction, and the subsequent cylindrical roller w falls sequentially from the chute 4a.

各円筒ころwは、シュート口4aから軸方向に平行な向きでその外径程度を落下するだけであり、しかも停止する水平な中心軸1やハウジング2の円筒状内壁に接触しながら転がり落ちるため、円環状空間3から外れる恐れはない。   Each cylindrical roller w only falls about the outer diameter in a direction parallel to the axial direction from the chute 4a, and also rolls down while making contact with the horizontal central shaft 1 that stops and the cylindrical inner wall of the housing 2. There is no fear of coming off the annular space 3.

ここで、後続の円筒ころwは、シュート口4aから落下して同様に転がり、やがて先の円筒ころwに接触することになる。先頭の円筒ころwは、後続の円筒ころw、w、w・・・から軸回転方向に押されて自重とバランスする位置で停止する。すなわち、先頭の円筒ころwは、円環状空間3の底を過ぎたところに停止し、中心軸1が停止する状態では、シュート口4aに先の円筒ころwが停止するまで後続の円筒ころwが供給される。その結果、シュート口4aの下方から円環状空間3の底を過ぎた範囲に亘って隣り合う円筒ころw、w同士が接触し、互いに周方向に押し合った状態で停止する。したがって、円筒ころw、wの傾きが抑制される条件を予め作り出した状態で中心軸1の回転を開始させられる。これにより、整列中に、各円筒ころwが傾き難くなり、円環状空間3から抜け出ることを防止することができる。   Here, the subsequent cylindrical roller w falls from the chute 4a and rolls in the same manner, and eventually comes into contact with the previous cylindrical roller w. The leading cylindrical roller w is pushed in the axial rotation direction from the subsequent cylindrical rollers w, w, w. That is, the leading cylindrical roller w stops after the bottom of the annular space 3, and when the central shaft 1 is stopped, the subsequent cylindrical roller w is stopped until the preceding cylindrical roller w stops at the chute 4 a. Is supplied. As a result, the adjacent cylindrical rollers w and w come into contact with each other over a range past the bottom of the annular space 3 from below the chute opening 4a, and stop in a state where they are pressed against each other in the circumferential direction. Therefore, the rotation of the central shaft 1 can be started in a state in which conditions for suppressing the inclination of the cylindrical rollers w and w are created in advance. Thereby, it becomes difficult to incline each cylindrical roller w during alignment, and can be prevented from coming out of the annular space 3.

この第1実施形態においては、円筒ころwの円環状空間3からの抜け出しを確実に防止するため、定数の円筒ころwの約半分が予め円環状空間3に供給される。これら予備供給ころ群w、w、w・・・が停止した状態で、中心軸1の回転が開始させられるので、中心軸1の回転時間が短縮される。その結果、省エネルギ化を図ることができる。また、先頭の円筒ころwが単独で連れ回されることもなく、その螺旋様の連れ回しも防止される。   In the first embodiment, about half of the constant number of cylindrical rollers w is supplied to the annular space 3 in advance in order to reliably prevent the cylindrical rollers w from coming out of the annular space 3. Since the rotation of the central shaft 1 is started in a state where these preliminary supply roller groups w, w, w... Are stopped, the rotation time of the central shaft 1 is shortened. As a result, energy saving can be achieved. Further, the leading cylindrical roller w is not rotated alone, and the spiral rotation is also prevented.

なお、上記予備供給ころ群の停止を検知するセンサ(図示省略)の出力に基づいて中心軸1の回転が開始されるようになっている。なお、上記予備供給ころ群w、w、w・・・の停止は先頭の円筒ころwの落下から概ね一定時間で生じるため、先頭の円筒ころwの落下検知、シュート口4aの開放検知等に基づく制御で中心軸1の回転を開始させるようにすることもできる。   The rotation of the central shaft 1 is started based on the output of a sensor (not shown) that detects the stop of the preliminary supply roller group. The stop of the preliminary supply roller group w, w, w... Occurs in a certain period of time from the fall of the leading cylindrical roller w, so that the leading cylindrical roller w is dropped, the chute 4a is opened, etc. It is also possible to start rotation of the central shaft 1 by the control based on the control.

図2に示すように、中心軸1が回転を開始すると、予備供給ころ群w、w、w・・・が互いに周方向に押し合った状態で連れ回される。シュート口4aの下方から円筒ころwが軸回転方向に移動し、重力シュート4に残る後続の円筒ころwが順次に中心軸1に落下していく。シュート口4aから落下した円筒ころwは、その転動面が軸方向に平行な向きで中心軸1の外周に接触し、速やかに中心軸1で連れ回される。   As shown in FIG. 2, when the central shaft 1 starts to rotate, the spare supply roller groups w, w, w... Are rotated in a state where they are pressed against each other in the circumferential direction. The cylindrical roller w moves from below the chute opening 4a in the axial rotation direction, and the subsequent cylindrical rollers w remaining on the gravity chute 4 are sequentially dropped onto the central shaft 1. The cylindrical roller w that has fallen from the chute 4a comes into contact with the outer periphery of the central shaft 1 with its rolling surface parallel to the axial direction, and is quickly rotated around the central shaft 1.

ここで、先に落下した円筒ころwがシュート口4aの下方から軸回転方向に移動すると後続の円筒ころwが中心軸1に落下するため、後続の円筒ころwが先の円筒ころwの直後に落下し、大きく離間することなく連れ回される。   Here, when the cylindrical roller w that has fallen first moves in the axial direction from below the chute 4a, the subsequent cylindrical roller w falls to the central shaft 1, so that the subsequent cylindrical roller w is immediately after the previous cylindrical roller w. It is dropped without being separated greatly.

先頭の円筒ころwの連れ回りは、ストッパ2aによりシュート口4aの直前で停止させられ、その場で先頭の円筒ころwが自転する。後続の円筒ころwも先の円筒ころwとの接触で連れ回りを停止させられ、その場で自転する。このため、定数の円筒ころは、効率よく円環状に整列させられる。   The rotation of the leading cylindrical roller w is stopped immediately before the chute 4a by the stopper 2a, and the leading cylindrical roller w rotates on the spot. The subsequent cylindrical roller w is also stopped by the contact with the previous cylindrical roller w, and rotates on the spot. For this reason, the constant cylindrical rollers are efficiently aligned in an annular shape.

通常、円筒ころwは、水平な軸回りに速やかに連れ回されるので、円環状空間3の外側に抜け出ることはないが、整列中、何らの原因で円筒ころwの一つが抜け出たとしても、ストッパ2aがあるため、抜け出た円筒ころwに後続する円筒ころwが間を詰めて整列させられる。重力シュート4には、予め定数以上の円筒ころw、w、w・・・が収納されており、円筒ころwが抜け出たとしても円筒ころの員数割れが防止される。要は、中心軸1の回転開始中に重力シュート4の円筒ころwが途切れないようにすればよい。   Normally, the cylindrical roller w is quickly swung around a horizontal axis, so it does not slip out of the annular space 3, but even if one of the cylindrical rollers w slips out for any reason during alignment, Since the stopper 2a is provided, the cylindrical roller w that follows the cylindrical roller w that has come out can be aligned in a short interval. The gravity chute 4 stores in advance cylindrical rollers w, w, w... Which are equal to or greater than a constant, and even if the cylindrical rollers w come out, the number of cylindrical rollers is prevented from breaking. In short, the cylindrical roller w of the gravity chute 4 may be prevented from being interrupted while the rotation of the central shaft 1 is started.

定数の円筒ころw、w、w・・・が円環状に整列させられた後、中心軸1の回転が停止させられ、図3に示すように、予め定位置に搬送された外方部材5の内方に向けて中心軸1とプッシャー6とが並行に前進する。これにより、ころ挿入空間が形成されつつ、その既形成部分にはプッシャー6の筒先端部に押された定数の円筒ころw、w、w・・・が一斉挿入されていく。シュート口4aに残った円筒ころwは、上記プッシャー6があるため、落下することができない。これを利用して、次サイクル用の円筒ころwが重力シュート4に補給され始める。   After the constant cylindrical rollers w, w, w... Are aligned in an annular shape, the rotation of the central shaft 1 is stopped, and the outer member 5 that has been conveyed to a predetermined position in advance as shown in FIG. The central shaft 1 and the pusher 6 advance in parallel toward the inside. As a result, while the roller insertion space is formed, a constant number of cylindrical rollers w, w, w... Pushed by the cylindrical tip of the pusher 6 are simultaneously inserted into the formed portion. The cylindrical roller w remaining in the chute 4a cannot fall because of the pusher 6. Utilizing this, the cylindrical roller w for the next cycle starts to be supplied to the gravity chute 4.

なお、シュート口4aにおける円筒ころwの詰りを検知するセンサの出力に基づいて中心軸1の回転停止と上記の一斉挿入が開始されるようになっている。整列完了の検知は、他の検知手段に基づくものでもよい。   The rotation stop of the central shaft 1 and the simultaneous insertion are started based on the output of a sensor that detects clogging of the cylindrical rollers w in the chute 4a. The detection of the completion of alignment may be based on other detection means.

また、上記ころ挿入空間が完全に形成された後にプッシャー6を前進させて一斉挿入を実施することも可能であるが、この第1実施形態のように並行することでサイクル時間を短縮することができる。   Further, after the roller insertion space is completely formed, the pusher 6 can be moved forward to perform simultaneous insertion. However, the cycle time can be shortened by performing parallel insertion as in the first embodiment. it can.

中心軸1とプッシャー6の前進位置は、外方部材5の軌道面と中心軸1の先端部外周の間に定数の円筒ころw、w、w・・・が位置するように調整されている。中心軸1は、前進位置に達した後、後退を開始する。この後退の間、プッシャー6は前進位置に停止しており、一斉挿入された円筒ころw、w、w・・・の後退がプッシャー6により規制された状態にある。   The forward movement positions of the central shaft 1 and the pusher 6 are adjusted so that constant cylindrical rollers w, w, w... Are positioned between the raceway surface of the outer member 5 and the outer periphery of the distal end portion of the central shaft 1. . The central shaft 1 starts to move backward after reaching the forward movement position. During this backward movement, the pusher 6 is stopped at the forward movement position, and the backward movement of the cylindrical rollers w, w, w... Inserted simultaneously is regulated by the pusher 6.

そして、中心軸1の後退と共に、受け治具8が、中心軸1の先端部外周と内方部材7の外径とが概ね隙間なく連続する状態を保つように前進する。これにより、内方部材7が中心軸1と反対側から外方部材5の内方に挿入され、両部材5、7の軌道面間に定数の円筒ころが円環状に整列された状態で挿入される。この挿入の間、プッシャー6が停止しているため、一斉挿入された円筒ころw、w、w、は、中心軸1の後退に引き摺られてころ挿入空間から抜け落ちることがない。   Then, as the central shaft 1 moves backward, the receiving jig 8 moves forward so that the outer periphery of the tip end portion of the central shaft 1 and the outer diameter of the inner member 7 are maintained substantially without any gap. As a result, the inner member 7 is inserted into the outer member 5 from the opposite side to the central shaft 1, and a constant number of cylindrical rollers are inserted between the raceways of the members 5 and 7 in an annular shape. Is done. Since the pusher 6 is stopped during this insertion, the cylindrical rollers w, w, w inserted simultaneously are not pulled out of the roller insertion space by being pulled back by the central shaft 1.

上記の一斉挿入後、図5に示すように、プッシャー6が後退する。このとき、先行して後退する中心軸1とハウジング2間に円環状空間3が既に形成されている。プッシャー6の後退により、シュート口4aが円環状空間3に開放され、既に補給を終えている次サイクルの円筒ころwの落下が始まり、図1の状態になる。また、受け治具8が後退し、組立体が後流側に搬送される。   After the simultaneous insertion, the pusher 6 moves backward as shown in FIG. At this time, an annular space 3 has already been formed between the central shaft 1 and the housing 2 that are retracted in advance. As the pusher 6 is retracted, the chute 4a is opened to the annular space 3, and the cylindrical roller w in the next cycle that has already been replenished starts to fall into the state shown in FIG. Further, the receiving jig 8 is retracted, and the assembly is conveyed to the downstream side.

なお、この第1実施形態においては、ストッパ2aがハウジング2に固定されており、プッシャー6は回転しないようになっている。図6に示すように、プッシャー6の筒壁に、その進退を可能にするため、ストッパ2aを通過させる空間6aが形成されている。空間6aは、溝状、スリット状など一斉挿入に支障がない限り適宜の形状にすることができる。また、ストッパ2aを昇降式にしてプッシャー6の進退時に上昇させるように構成することもできるが、装置の単純化を考慮すると固定式がよい。   In the first embodiment, the stopper 2a is fixed to the housing 2 so that the pusher 6 does not rotate. As shown in FIG. 6, a space 6 a through which the stopper 2 a passes is formed in the cylindrical wall of the pusher 6 in order to enable advancement and retraction. The space 6a can have an appropriate shape as long as there is no hindrance to simultaneous insertion, such as a groove shape or a slit shape. Further, the stopper 2a can be lifted and lowered so as to be raised when the pusher 6 advances and retreats. However, in view of simplification of the apparatus, a fixed type is preferable.

上述のように、この第1実施形態においては、各円筒ころwが水平軸回りに連れ回されるため、円環状空間3を閉じるシャッターが不要になる。
また、この第1実施形態においては、シュート口4aから落下した円筒ころwは、その転動面が軸方向に平行な向きで中心軸1の外周に接触し、速やかに中心軸で連れ回されるので、ハウジング2に漏斗状のガイドを設ける必要がない。
また、この第1実施形態においては、後続の円筒ころwが先の円筒ころwの直後に落下し、速やかに連れ回されるため、中心軸1をみそすり運動させなくとも、定数の円筒ころw、w、w・・・は、効率よく円環状に整列させられる。
As described above, in the first embodiment, since each cylindrical roller w is rotated around the horizontal axis, a shutter for closing the annular space 3 becomes unnecessary.
In the first embodiment, the cylindrical roller w dropped from the chute 4a contacts the outer periphery of the central shaft 1 with its rolling surface parallel to the axial direction, and is quickly rotated along the central shaft. Therefore, it is not necessary to provide a funnel-shaped guide in the housing 2.
In the first embodiment, the subsequent cylindrical roller w falls immediately after the previous cylindrical roller w and is quickly rotated, so that a constant number of cylindrical rollers can be obtained without causing the center shaft 1 to shave. w, w, w... are efficiently aligned in an annular shape.

したがって、この第1実施形態においては、シャッターやガイドが不要になり、装置を単純かつコンパクトにしつつ、定数の円筒ころを効率よく整列させることができる。   Therefore, in the first embodiment, a shutter and a guide are not required, and a constant number of cylindrical rollers can be efficiently aligned while making the apparatus simple and compact.

上述の第1実施形態において装置の単純化を優先する場合、中心軸1とプッシャー6とを一体に設けることができる。例えば、第2実施形態として図7、図8に示すように、中心軸1の先端部外周に連続するように形成された肩部をプッシャー6とした構成を採用することができる。   When priority is given to simplification of the apparatus in the first embodiment, the central shaft 1 and the pusher 6 can be provided integrally. For example, as shown in FIGS. 7 and 8 as the second embodiment, it is possible to employ a configuration in which a shoulder portion formed so as to be continuous with the outer periphery of the distal end portion of the central shaft 1 is a pusher 6.

この第2実施形態においては、プッシャー6が中心軸1と一体に進退及び回転することになる。このため、中心軸1の進退時にプッシャー6がストッパ2aと干渉しないようにする必要がある。この第2実施形態においては、プッシャー6の外径を第1実施形態より小径にすることで干渉が回避されている。   In this second embodiment, the pusher 6 advances and retreats and rotates integrally with the central shaft 1. For this reason, it is necessary to prevent the pusher 6 from interfering with the stopper 2a when the central shaft 1 advances and retreats. In the second embodiment, interference is avoided by making the outer diameter of the pusher 6 smaller than that of the first embodiment.

中心軸1の後退速度は、挿入された円筒ころw、w、wが勢いよく引き摺られて抜け落ちないようにするため、第1実施形態より遅めに調整される。   The retraction speed of the central shaft 1 is adjusted later than that of the first embodiment in order to prevent the inserted cylindrical rollers w, w, w from being dragged vigorously.

また、上述の第1実施形態及び第2実施形態においては、シュート口4aから落下した円筒ころwが中心軸1の中心線cの直上から軸回転方向側に外れた位置に接触するようにしたが、中心線cの直上に接触するように構成することも可能である。   Further, in the first and second embodiments described above, the cylindrical roller w dropped from the chute 4a is brought into contact with a position deviated from the position directly above the center line c of the central shaft 1 to the axial rotation direction side. However, it is also possible to configure so as to contact directly above the center line c.

係る構成の採用した例を第3実施形態として図9、図10に示す。この第3実施形態においては、シュート口4aから落下した円筒ころwが中心線cの直上に接触する。このため、サイクル初期段階において、先頭の円筒ころwは、予め重力シュート4に収納された円筒ころw、w、w・・・に押されて中心軸1と後続の円筒ころwとの間に挟まれ、転がり落ちることなく停止するようになっている。このため、重力シュート4における円筒ころwの収納数の管理を容易に行うことができる。   An example in which such a configuration is adopted is shown in FIGS. 9 and 10 as a third embodiment. In the third embodiment, the cylindrical roller w that has fallen from the chute 4a is in contact with the center line c. For this reason, at the initial stage of the cycle, the leading cylindrical roller w is pushed between the cylindrical rollers w, w, w... It is sandwiched and stops without rolling down. For this reason, the number of cylindrical rollers w stored in the gravity chute 4 can be easily managed.

中心軸1の回転が開始させられると、先頭の円筒ころwが勢いよく走り、後続の円筒ころwと離れる先走り現象が起こり、円環状空間3から抜け出ることがあり得るが、ストッパ2aがあり、また、抜け出た分の円筒ころwを供給可能なため、定数の円筒ころw、w、w・・・を支障なく整列させることができる。   When the rotation of the central shaft 1 is started, the leading cylindrical roller w runs vigorously, and a pre-run phenomenon that separates from the subsequent cylindrical roller w may occur, and may escape from the annular space 3, but there is a stopper 2a. Further, since it is possible to supply the cylindrical rollers w that have slipped out, it is possible to align constant cylindrical rollers w, w, w.
