Description

本発明は、頭部と棒状のネジ部を有した金属製ネジ類やこれと類似の金属製リベットや鋲等を多数収容して、これらを分離整列して一個ずつ排出し供給するネジ類供給装置に関し、特に、大型の金属製ネジ類のネジ類供給装置に関する。   The present invention accommodates a large number of metal screws having a head portion and a rod-like screw portion or a similar metal rivet, rivet, etc., and supplies and supplies them by separating and arranging them one by one. More particularly, the present invention relates to a screw supply device for large metal screws.

従来、この種のネジ類供給機としては、本発明者らは特許文献1としてネジ類送給装置を提供している。このネジ類送給装置は、ネジ類Sが多数収容される収容部を設け、収容部の内部から外部に突出しネジ類Sが挿入される溝を有し、排出されるネジ類Sを案内するレールを設け、収容部内のレールにネジ類Sを供給する供給部を設けたもので、ネジ類Sは前記レールの排出側端部のストッパ部材に整列して待機するようにしたものである。
上記のネジ類Sを供給する供給部は、上下動するスクイ板を設けてネジ類Sを押し上げてレール上に載置する構成であり、スクイ板の容量に限度があるので余り多くのネジ類Sを収容できず、すなわち、収容部を大きくしてもスクイ板にネジ類Sを載置できる個数に限度があった。
Conventionally, as a screw feeder of this type, the present inventors have provided a screw feeder as Patent Document 1. This screw feeding device is provided with a housing portion in which a large number of screws S are housed, has a groove that protrudes from the inside of the housing portion to the outside and into which the screws S are inserted, and guides the ejected screws S. A rail is provided, and a supply portion for supplying screws S to the rail in the housing portion is provided. The screws S are arranged in a standby state on the stopper member at the discharge side end portion of the rail.
The supply unit for supplying the screws S has a configuration in which a squeeze plate that moves up and down is provided and the screws S are pushed up and placed on the rail. Since the capacity of the squeeze plate is limited, there are too many screws. S cannot be accommodated, that is, there is a limit to the number of screws S that can be placed on the squeeze plate even if the accommodation portion is enlarged.

また、スクイ板から一挙に多くのネジ類がレール上に落下するので、複数のネジ類Sが重なって絡み合い、分離整列が不十分で複数のネジ類Sが一緒に排出してしまうという不都合があり、確実性に問題点があった。
一方、少量の金属製部材を、収容部の外側に往復動するプレートを設け、このプレートに磁石をとりつけ、磁石の磁力で少量の金属製部材を収容部から取り出し、収容部の上部のスクレーパで金属部材を掻き取って、金属部材を1個ずつ供給する部品供給装置が、特許文献2として提案されている。この供給装置は、部品を一個ずつ供給できるが、プレートが往復動するので機構が複雑になり、部品の摩耗が多いうえ、スクレーパで金属部材を掻き取って分離するので、部材に傷がつくことがあるという問題点もあり、そのため、部品の受け渡し部材を種々用意する必要もあった。
In addition, since many screws fall on the rail at a time from the squeeze plate, the plurality of screws S overlap each other and become intertwined, and the separation and alignment are insufficient, and the plurality of screws S are discharged together. There was a problem with certainty.
On the other hand, a plate that reciprocates a small amount of metal member is provided on the outside of the housing portion, a magnet is attached to this plate, a small amount of metal member is taken out of the housing portion by the magnetic force of the magnet, and a scraper above the housing portion is used. Patent Document 2 proposes a component supply device that scrapes metal members and supplies metal members one by one. This supply device can supply parts one by one, but the plate reciprocates, the mechanism becomes complicated, parts wear much, and the scraper scrapes and separates the metal parts, which can damage the parts. For this reason, it is necessary to prepare various parts transfer members.

ここで、本発明者らは、磁石を用いてネジ類Sを汲み上げて、収容部を深くしてネジ類Sを収納する容積を大きくするネジ類供給装置として、特許文献3を提案しており、このネジ類を収容部から汲取機構は、ネジ類の収容部の外壁の壁面に沿って回転する回転腕部を設け先端に磁石を固着し、回転腕部は収容部の外壁から収納部に積載されたネジ類を磁石による吸着力により、ネジ類を汲み上げ誘導し、回転腕部の磁石が上方で外壁から外側に離反させ、搬送機構に送り込む構成を採用している。   Here, the present inventors have proposed Patent Document 3 as a screw supply device that pumps up the screws S using a magnet and deepens the storage portion to increase the volume for storing the screws S. The mechanism for fetching the screws from the housing portion is provided with a rotating arm portion that rotates along the wall surface of the outer wall of the screw housing portion, and a magnet is fixed to the tip, and the rotating arm portion is moved from the outer wall of the housing portion to the housing portion. A configuration is adopted in which the loaded screws are pumped up and guided by the attraction force of the magnet, and the magnet of the rotating arm part is separated upward from the outer wall and sent to the transport mechanism.

ところで、従来のネジ類供給装置は、磁石による吸着力を余り強くすることができず、ネジの直径が太さが1cm以上の重量のあるネジの汲み取りには不向きであった。また、ネジ類を吸着する位置の枠体の側壁の近傍に限られ、側壁から離れた位置はネジ類を汲み上げられないといった問題点もあった。
本発明は、このような問題点に鑑みてなされたもので、ネジ類供給装置において、大型の重量のあるネジ類Sを大量に供給可能としたネジ類供給装置を提供しようとするものである。
By the way, the conventional screw supply device cannot make the attraction force of the magnet so strong, and is unsuitable for pumping a screw having a screw diameter of 1 cm or more in weight. In addition, there is a problem that the screws are limited to the vicinity of the side wall of the frame at a position where the screws are adsorbed, and the screws cannot be pumped away from the side wall.
The present invention has been made in view of such a problem, and an object of the present invention is to provide a screw supply device that can supply a large amount of large and heavy screws S in a screw supply device. .

本発明のネジ類供給装置の発明によれば、ネジ類を直接電磁石部に吸着させる構成であるので、強力に磁力をネジ類に作用させることができ、且つ、収納部の上部から下降することができるので、電磁石部に大型の重量のあるネジ類Sを吸着して移動することができ、収納部さえ大容量にすれば供給回数を減らすことができる。
また、電磁石を採用することにより、金属ネジ類の吸着と離反との制御は電源のON/OFFだけでよく、不必要な箇所でのネジ類の吸着も防げ簡単な構成が可能になり、力が加わらず自然にネジが落下するので、ネジ類に傷を与えることがなく、ネジ類供給装置の収納部等の部材の摩耗も少ないという作用効果を有する。更に、電磁石部の移動に長尺のチェーン部材を用いることにより、大型の電磁石部を垂直及び水平方向に移動することができ、設計の自由度を増すことができる。

According to the invention of the screw supply device of the present invention, since the screws are directly attracted to the electromagnet portion, the magnetic force can be strongly applied to the screws and lowered from the upper portion of the storage portion. Therefore, the large and heavy screws S can be attracted and moved to the electromagnet part, and the number of times of supply can be reduced if the capacity of the storage part is increased.
In addition, by adopting an electromagnet, it is only necessary to turn on and off the power supply to control the adsorption and separation of the metal screws, and it is possible to prevent the adsorption of screws at unnecessary places and to make a simple configuration. Since the screws fall naturally without being added, there is an effect that the screws are not damaged and the members such as the storage portion of the screw supply device are less worn. Furthermore, by using a long chain member for moving the electromagnet portion, the large electromagnet portion can be moved in the vertical and horizontal directions, and the degree of design freedom can be increased.
Since the guide rail member which vibrates is used for the conveyance mechanism which conveys the screws, the screws can be supplied quickly and reliably.

図7乃至図12に示すように、汲取機構3はネジSを電源の投入及び切断により吸着又離反させて制御する電磁石311を用いた電磁石部31を設け、電磁石部31は移動する長尺のチェーン部材32の先端部321(図9参照)に設けられ、長尺のチェーン部材32の後端部322はネジ類供給装置1の枠体11の背面部15の適所の上部151(図6参照)に固定され、チェーン部材32の後端部322と先端部321との間にチェーン部材32を繰出し或いは引き揚げるチェーン駆動モータ33を設け、チェーン駆動モータ33と電磁石部31との間にはチェーン部材32をスプロケット341に係合しながら水平に移動するリアスライド部34が設けられている。
なお、チェーン駆動モータ33は、噛み合うギヤ331ギヤ332によって、両側面部18に設けた一対の駆動軸333及びスプロケット334を駆動し、このスプロケット334にチェーン部材32に噛み合い、これによって、チェーン部材32を巻き上げ及び繰り出し作用を行う。
リアスライド部34は収納部2とスクレーパ部41(図2参照)との上部の間を水平に移動するとともに収納部2の上部で停止する停止機構352と、スクレーパ部41の上部で停止する停止機構(ホームポジション)351(図8参照)とが設けられている。
[Drawing mechanism 3]
As shown in FIG. 7 to FIG. 12, the drawing mechanism 3 is provided with an electromagnet portion 31 using an electromagnet 311 that controls the screw S by attracting or separating it by turning on and off the power, and the electromagnet portion 31 is a long moving piece. The rear end 322 of the long chain member 32 is provided at the front end 321 (see FIG. 9) of the chain member 32, and the upper portion 151 (see FIG. 6) of the rear portion 15 of the frame 11 of the screw supply device 1 is placed. ) And a chain drive motor 33 is provided between the rear end portion 322 and the front end portion 321 of the chain member 32 to feed or lift the chain member 32, and the chain member is interposed between the chain drive motor 33 and the electromagnet portion 31. A rear slide portion 34 is provided that moves horizontally while engaging 32 with the sprocket 341.
The chain drive motor 33 drives a pair of drive shafts 333 and sprockets 334 provided on both side surface portions 18 by meshing gears 331 and gears 332, and meshes with the chain members 32 by the sprockets 334, thereby causing the chain members 32 to move. Performs hoisting and feeding operations.
The rear slide part 34 moves horizontally between the upper parts of the storage part 2 and the scraper part 41 (see FIG. 2) and stops at the upper part of the storage part 2 and stops stopped at the upper part of the scraper part 41 A mechanism (home position) 351 (see FIG. 8) is provided.

次に、リアスライド部34の移動は、ネジSを収納部2から汲み取る工程で、リアスライド部34にチェーン部材32で引き揚げられ、電磁石部31がスクレーパ部41の上部の停止機構(ホームポジション)351の位置に停止しているが、リアスライド部34に接触した状態の電磁石部31は、チェーン駆動モータ33によってチェーン部材32が繰り出され、チェーン部材32の引っ張り力が無くなると、リアスライド部34が収納部2側に引っ張る引張機構36により前面部16(図3参照)側の前方に水平に移動する。
リアスライド部34は停止機構352により収納部2の上部で停止し、なおも繰り出されるチェーン部材32によって電磁石部31は、停止機構352の位置でリアスライド部34のスプロケット341で移動方向を変えて収納部2のネジ部S1が存在する位置まで降下し、下降した状態で電磁石31の電源を投入してネジS類を吸着する。
Next, the movement of the rear slide part 34 is a process of drawing the screw S from the storage part 2, and is pulled up to the rear slide part 34 by the chain member 32, and the electromagnet part 31 is a stop mechanism (home position) above the scraper part 41. The electromagnet 31 that is stopped at the position 351 but is in contact with the rear slide 34 is fed out by the chain drive motor 33, and when the tension of the chain 32 is lost, the rear slide 34 is removed. Is moved horizontally in front of the front surface portion 16 (see FIG. 3) by the pulling mechanism 36 that pulls toward the storage portion 2 side.
The rear slide portion 34 is stopped at the upper portion of the storage portion 2 by the stop mechanism 352, and the electromagnet portion 31 is changed in the moving direction by the sprocket 341 of the rear slide portion 34 at the position of the stop mechanism 352 by the chain member 32 that is drawn out. The storage part 2 descends to a position where the screw part S1 exists, and in the lowered state, the electromagnet 31 is turned on to attract the screws S.

その後、ネジSの吸着作動を終了すると、吸着した電磁石部31はチェーン駆動モータ33で駆動されるスプロケット334によりチェーン部材32を引き揚げることにより上方に移動する。ここで、停止機構352の位置でリアスライド部34が収納部2の上部まで上昇を完了すると、チェーン駆動モータ33のでチェーン部材32を引き揚げ力が引張機構36の引張力よりも大きいので、リアスライド部34は停止機構352から背面部15(図3参照)側の後方に水平に移動する。
そして、チェーン駆動モータ33によるチェーン部材32を引き揚げ力によりリアスライド部34が収納部2からスクレーパ部41の上部まで引張機構36の引張力に抗して移動して、停止機構(ホームポジション)351により停止し、停止と同時に電磁石311の電源を切断してネジSを離反してスクレーパ部41に落下させ、落下したネジSはスクレーパ部41から搬送機構4(図13参照)に載置する工程を適宜繰り返す。
Thereafter, when the suction operation of the screw S is finished, the attracted electromagnet portion 31 moves upward by lifting the chain member 32 by the sprocket 334 driven by the chain drive motor 33. Here, when the rear slide part 34 completes the raising to the upper part of the storage part 2 at the position of the stop mechanism 352, the chain drive motor 33 pulls up the chain member 32 and the pulling force of the pulling mechanism 36 is larger. The part 34 moves horizontally from the stop mechanism 352 to the rear side on the back face part 15 (see FIG. 3) side.
Then, the rear slide portion 34 moves from the storage portion 2 to the upper portion of the scraper portion 41 against the pulling force of the pulling mechanism 36 due to the pulling force of the chain member 32 by the chain drive motor 33, and a stop mechanism (home position) 351. The power supply of the electromagnet 311 is cut off simultaneously with the stop, the screw S is separated and dropped onto the scraper unit 41, and the dropped screw S is placed on the transport mechanism 4 (see FIG. 13) from the scraper unit 41. Repeat as appropriate.

収納部2とスクレーパ部41との上部の間を水平移動するリアスライド部34は、リアスライド部34を常に引張機構36によって前方の収納部2及び排出部6側(図3参照)に引っ張られているが、この引張機構36は巻き取りバネやエヤーシリンダー等の一定の推力を有する機構によって構成されるが、本実施例では巻取りバネを用いた引張機構36で説明する。なお、エヤーシリンダーを用いた引張機構36の場合は高価であるが推力の設定を可変とすることが容易であり、耐久性も向上する。
本実施例においては、引張機構36は巻き取りバネ361によって構成されが、引っ張り力はチェーン駆動モータ33の引き揚げ(巻上げ)力よりは弱く設定されている。
リアスライド部34はネジ類供給装置1の枠体11の上部に背面部15から前面部16に亘って掛け渡されたレール部材35に沿って移動するように設けられている。
したがって、チェーン駆動モータ33のチェーン部材32の繰り出しに伴い、ネジ類供給装置1のレール部材35に沿って水平移動し、収納部2の上部のレール部材35にはリアスライド部34が移動するのを阻止する停止機構352が設けられ、そこからは電磁石部31は下降するようになっている。また、逆方向の搬送機構4のスクレーパ部41の上部にもリアスライド部34を移動を阻止する停止機構(ホームポジション)351が設けられ、この停止機構351はネジ類供給装置1が稼働しない場合の電磁石部31のがホームポジションとなる。
The rear slide part 34 that horizontally moves between the upper part of the storage part 2 and the scraper part 41 is always pulled by the pulling mechanism 36 toward the front storage part 2 and the discharge part 6 (see FIG. 3). However, the tension mechanism 36 is constituted by a mechanism having a constant thrust such as a winding spring or an air cylinder. In this embodiment, the tension mechanism 36 using a winding spring will be described. The tension mechanism 36 using an air cylinder is expensive, but it is easy to make the thrust setting variable, and the durability is improved.
In the present embodiment, the pulling mechanism 36 is constituted by a take-up spring 361, but the pulling force is set to be weaker than the pulling (winding) force of the chain drive motor 33.
The rear slide portion 34 is provided so as to move along a rail member 35 that extends from the back surface portion 15 to the front surface portion 16 on the upper portion of the frame body 11 of the screw supply device 1.
Therefore, as the chain member 32 of the chain drive motor 33 is extended, it moves horizontally along the rail member 35 of the screw supply device 1, and the rear slide portion 34 moves to the rail member 35 on the upper portion of the storage portion 2. A stop mechanism 352 is provided to prevent the electromagnet 31 from descending. Further, a stop mechanism (home position) 351 for preventing the rear slide part 34 from moving is also provided on the upper part of the scraper part 41 of the transport mechanism 4 in the reverse direction, and this stop mechanism 351 is used when the screw supply device 1 is not operated. The electromagnet part 31 is the home position.

なお、図2及び図4の枠体11の収納部2がある側面部18には、収納部2の積載されたネジSの積載山の高さを測定し、電磁石部31の下降位置を制御するためのネジ残量センサー181が設けられ、また、ネジ残量センサー181は対向する側面部18にも設けられている。また、スクレーパ部41がある側面部18には、電磁石部31が稼働しない場合等に、電磁石部31が待機する停止機構(ホームポジション)351になる位置に制御するために、原点センサー3511が設けられている。
主に図4、図6に示されるように、長尺のチェーン部材32の背面部15の適所に固定された後端部322(図10参照)とチェーン駆動モータ33との間には、チェーン部材32を係合しながら上下に移動するバランサーウェイト37が設けられ、チェーン駆動モータ33で引き揚げ(巻上げ)ることにより弛んだチェーン部材32を収納する。バランサーウェイト37の上下によりチェーン部材32の弛みを吸収するようにしたのは、軸に巻き取った場合には大きな巻径になり巻取り装置の扱い場所が困難であるが、バランサーウェイト37であると枠体11の背面部15の薄い箱体スペースを利用できるからである。
2 and 4, the height of the piles of the screws S loaded in the storage unit 2 is measured on the side surface 18 where the storage unit 2 of the frame 11 is located, and the lowered position of the electromagnet unit 31 is controlled. The screw remaining amount sensor 181 is provided for the purpose, and the screw remaining amount sensor 181 is also provided on the opposite side surface portion 18. In addition, an origin sensor 3511 is provided on the side surface portion 18 where the scraper portion 41 is provided in order to control the electromagnet portion 31 to a stop mechanism (home position) 351 when the electromagnet portion 31 is not operated. It has been.
As shown mainly in FIGS. 4 and 6, there is a chain between the rear end 322 (see FIG. 10) fixed in place on the back surface 15 of the long chain member 32 and the chain drive motor 33. A balancer weight 37 that moves up and down while engaging the member 32 is provided, and the chain member 32 that is slackened by being pulled up (wound up) by the chain drive motor 33 is stored. The reason why the slack of the chain member 32 is absorbed by the balancer weight 37 is that the balancer weight 37 has a large winding diameter when it is wound around the shaft and the handling place of the winding device is difficult. This is because a thin box space on the back surface 15 of the frame 11 can be used.

次に、リアスライド部34及び電磁石部31の移動工程を、主に、図7から図12を参照して説明する。
[電磁石部31の待機状態、スタート位置]
先ず、電磁石部31が待機状態、或いは、スタートの停止機構351でホームポジションにある斜視図の図7とその側面図の図10で説明する。
図7、図10において、チェーン駆動モータ33でチェーン部材32が引き揚げ(巻上げ)られリアスライド部34及び電磁石部31は、原点センサー3511の検知により停止機構351が作動しホームポジション(351)で停止している。この停止機構351でありホームポジションは、待機状態或いはスタート位置でもあるが、搬送機構4(図13参照)を構成するスクレーパ41の上部に位置する。
この位置では、電磁石部31の電磁石311の電源はOFFされており、ネジSの吸着がなくネジSを離反しており、自然にネジSが落下している。電磁石部31の電源のON/OFFで吸着/離反を行うのでネジSに傷を与えることがなく、ネジ類供給装置1の部材の摩耗も少ない。
また、チェーン駆動モータ33により引き揚げられたチェーン部材32は、背面部15のチェーン部材32を下降するバランサーウェイト37の両端のスプロケット371に嵌合しながら下方に垂れ下がり背面部15に形成される空間に貯留される。バランサーウェイト37は両側面部18(図1,2参照)に沿った一対のレール部材372に沿って上下動してチェーン部材32を案内するが、このバランサーウェイト37は必ずしも無くても良いが、チェーン部材32が互いに接触して絡み合うのを防ぐためにはスプロケット371付のバランサーウェイト37を設けた方が良い。
Next, the movement process of the rear slide part 34 and the electromagnet part 31 is demonstrated mainly with reference to FIGS.
[Standby state of electromagnet 31 and start position]
First, FIG. 7 of a perspective view in which the electromagnet portion 31 is in a standby state or at a home position with a start stop mechanism 351 and FIG. 10 of a side view thereof will be described.
7 and 10, the chain member 32 is lifted (wound up) by the chain drive motor 33, and the rear slide part 34 and the electromagnet part 31 are stopped at the home position (351) by operating the stop mechanism 351 upon detection of the origin sensor 3511. doing. The home position of the stop mechanism 351 is a standby state or a start position, but is positioned above the scraper 41 constituting the transport mechanism 4 (see FIG. 13).
At this position, the power source of the electromagnet 311 of the electromagnet portion 31 is turned off, the screw S is not attracted and the screw S is separated, and the screw S is naturally dropped. Since the adsorption / separation is performed by turning on / off the power supply of the electromagnet portion 31, the screw S is not damaged and the wear of the members of the screw supply device 1 is small.
Further, the chain member 32 pulled up by the chain drive motor 33 hangs down while being fitted to the sprockets 371 at both ends of the balancer weight 37 that descends the chain member 32 of the back surface portion 15, and is formed in the space formed in the back surface portion 15. Stored. The balancer weight 37 moves up and down along the pair of rail members 372 along the side surface portions 18 (see FIGS. 1 and 2) to guide the chain member 32. However, the balancer weight 37 is not necessarily provided, In order to prevent the members 32 from coming into contact with each other and entangled, it is better to provide a balancer weight 37 with a sprocket 371.

[リアスライド部34の前進水平移動]
ここで、汲み取り動作を開始する指令が、汲取機構3に指示されると、リアスライド部34は前面部16(図1参照)の収納部2に向かって前進水平移動するが、これを図8、図11で説明する。
チェーン駆動モータ33でチェーン部材32が繰り出されると、リアスライド部34を常に引張機構36によって前方の収納部2側に引っ張られているので、この引張機構36によって、両側面部18まで掛け渡されたリアスライド部34が、両側面部18の上部に設けられた一対のレール部材35に沿って、収納部2に向かって前進水平移動する。
前進水平移動したリアスライド部34が収納部2の真上まで移動すると、レール部材35に設けられた停止機構(図7参照)352のストッパー3521によってリアスライド部34は前進を阻止される。
また、チェーン駆動モータ33により引き揚げられていたチェーン部材32の一部が繰り出され、背面部15のチェーン部材32をバランサーウェイト37も中間部まで上昇する。
[Rear slide part 34 moves forward and horizontally]
Here, when a command to start the pumping operation is instructed to the pumping mechanism 3, the rear slide portion 34 moves forward and horizontally toward the storage portion 2 of the front surface portion 16 (see FIG. 1). This will be described with reference to FIG.
When the chain member 32 is fed out by the chain drive motor 33, the rear slide part 34 is always pulled to the front storage part 2 side by the pulling mechanism 36, so that it is stretched to the side surface parts 18 by the pulling mechanism 36. The rear slide portion 34 moves forward and horizontally toward the storage portion 2 along a pair of rail members 35 provided on the upper portions of the side surface portions 18.
When the rear slide part 34 that has moved forward and moved to a position directly above the storage part 2, the rear slide part 34 is prevented from moving forward by a stopper 3521 of a stop mechanism (see FIG. 7) 352 provided on the rail member 35.
Further, a part of the chain member 32 pulled up by the chain drive motor 33 is fed out, and the balancer weight 37 of the chain member 32 on the back surface portion 15 is also raised to the middle portion.

[電磁石部31の垂直下降移動(ネジ吸着)]
前進水平移動したリアスライド部34が収納部2の真上まで移動し、主に、図9、図12に示すように、停止機構352のストッパー3521によってリアスライド部34は前進を阻止され、なおもチェーン駆動モータ33でチェーン部材32を繰り出されると、チェーン部材32は下方に方向を変えて、先端部321(図12参照)に取り付けられている電磁石部31が下降する。
この下降する距離は、収納部2の側面部18の上部に設けられたネジ残量センサー181(図2参照)の検出値から算出される。この場合にネジ残量センサー181は複数設けてその平均値を採用してもよい。なお、このネジ残量センサー181は稼働開始時にだけ作動させ、誤作動を防ぐため電磁石部31の下降時は作動しないようにしている。
このように、繰り出されるチェーン部材32によって電磁石部31は、リアスライド部34で移動方向を変えて収納部2で積載させるネジSが存在する頂部の位置まで降下する。ここで、電磁石部31が下降した状態で電磁石311の電源を投入して磁力でネジSを電磁石311に吸着する。
このとき、チェーン駆動モータ33によりチェーン部材32の一部が繰り出され、背面部15のチェーン部材32のバランサーウェイト37も上部まで上昇する。なお、バランサーウェイト37が作用したことにより、収納については単に末端をたれ下げた場合よりも、折りたたみ状態となって半分の距離ですみ、チェーン部材32の後端部322、及び電磁石311のリード線の末端部(図示せず)を、背面部15のチェーン部材32の収納空間の上部に固定することができる。
[Vertical downward movement of electromagnet 31 (screw adsorption)]
The rear slide part 34 that has moved forward and moved to a position directly above the storage part 2. As shown mainly in FIGS. 9 and 12, the rear slide part 34 is prevented from moving forward by a stopper 3521 of the stop mechanism 352. When the chain member 32 is fed out by the chain drive motor 33, the direction of the chain member 32 is changed downward, and the electromagnet portion 31 attached to the tip portion 321 (see FIG. 12) is lowered.
This descending distance is calculated from the detection value of the remaining screw amount sensor 181 (see FIG. 2) provided on the upper portion of the side surface portion 18 of the storage portion 2. In this case, a plurality of remaining screw sensors 181 may be provided and the average value thereof may be adopted. The screw remaining amount sensor 181 is activated only at the start of operation, and is not activated when the electromagnet portion 31 is lowered to prevent malfunction.
In this way, the electromagnet portion 31 is lowered to the position of the top where the screw S to be loaded on the storage portion 2 is changed by changing the moving direction at the rear slide portion 34 by the chain member 32 that is fed out. Here, the electromagnet 311 is turned on while the electromagnet portion 31 is lowered, and the screw S is attracted to the electromagnet 311 by a magnetic force.
At this time, a part of the chain member 32 is fed out by the chain drive motor 33, and the balancer weight 37 of the chain member 32 on the back surface 15 is also raised to the upper part. Since the balancer weight 37 is actuated, the folded state is only half the distance when the end is simply lowered, and the rear end 322 of the chain member 32 and the lead wire of the electromagnet 311 are required. Can be fixed to the upper part of the storage space of the chain member 32 of the back surface portion 15.

[電磁石部31の垂直上昇移動(ネジ吸着移動)]
電磁石部31の電磁石311に電源を投入して磁力でネジSを電磁石311に吸着させると、チェーン駆動モータ33は逆転してチェーン部材32の引き揚げを開始する。以後は電磁石部31の挙動は逆になり、図9(図12)→図8(図11)→図7(図10)の順に移動する。
これを説明するが、チェーン部材32の引き揚げを開始すると、リアスライド部34を常に引張機構36によって前方の収納部2側に引っ張られているので、先ず、電磁石部31が上昇してレール部材35上で停止しているリアスライド部34まで移動する。
このとき、チェーン駆動モータ33によりチェーン部材32の一部が引き揚げられ、背面部15のチェーン部材32のバランサーウェイト37も中間部まで下降する。
[Vertical upward movement of electromagnet part 31 (screw adsorption movement)]
When power is turned on to the electromagnet 311 of the electromagnet portion 31 and the screw S is attracted to the electromagnet 311 by a magnetic force, the chain drive motor 33 rotates in the reverse direction and starts to lift the chain member 32. Thereafter, the behavior of the electromagnet unit 31 is reversed and moves in the order of FIG. 9 (FIG. 12) → FIG. 8 (FIG. 11) → FIG. 7 (FIG. 10).
Although this will be described, when the lifting of the chain member 32 is started, the rear slide portion 34 is always pulled to the front storage portion 2 side by the pulling mechanism 36. Therefore, first, the electromagnet portion 31 is raised and the rail member 35 is lifted. It moves to the rear slide part 34 stopped above.
At this time, a part of the chain member 32 is pulled up by the chain drive motor 33, and the balancer weight 37 of the chain member 32 of the back surface part 15 is also lowered to the intermediate part.

[リアスライド部34の後退水平移動]
電磁石部31がリアスライド部34まで上昇し、なおもチェーン駆動モータ33によりチェーン部材32が引き揚げられると、図8、図11、図13に示すように、リアスライド部34は引張機構36の引っ張り力に抗して、背面部15(図3参照)側でスクレーパ部41側(図13参照)に後退し水平移動する。そして、電磁石部31が待機状態、或いは、スタートの位置である停止機構351のホームポジションの位置まで後退し、図7、図10に示すように、原点センサー3511が電磁石部31(リアスライド部34でも良い)の位置を検知し、停止機構(ホームポジション)351(図8参照)が稼働して、チェーン駆動モータ33の駆動を停止する。
このとき、チェーン駆動モータ33によりチェーン部材32が引き揚げられ、背面部15のチェーン部材32をバランサーウェイト37も背面部15の下部まで下降する。
リアスライド部34の停止と同時に、電磁石部31の電磁石311への電源供給を切断して、ネジSを電磁石部31から離反させ、全てのネジSを搬送機構4のスクレーパ部41に落下させ、落下したネジSはスクレーパ部41に積載するとともに、搬送機構4の案内レール部材43に案内され、以後の工程に移行する。
以後は、汲取機構3は必要により、以上の工程を繰り返して、ネジSの汲み取り作業を繰り返す。
[Reverse horizontal movement of rear slide part 34]
When the electromagnet portion 31 rises to the rear slide portion 34 and the chain member 32 is pulled up by the chain drive motor 33, the rear slide portion 34 is pulled by the tension mechanism 36 as shown in FIGS. Against the force, the rear part 15 (see FIG. 3) side moves backward to the scraper part 41 side (see FIG. 13) and moves horizontally. Then, the electromagnet unit 31 is in a standby state or retreats to the home position of the stop mechanism 351 that is the start position, and the origin sensor 3511 is moved to the electromagnet unit 31 (rear slide unit 34) as shown in FIGS. However, the stop mechanism (home position) 351 (see FIG. 8) is activated to stop the drive of the chain drive motor 33.
At this time, the chain member 32 is pulled up by the chain drive motor 33, and the balancer weight 37 of the chain member 32 on the back surface portion 15 is lowered to the lower portion of the back surface portion 15.
Simultaneously with the stop of the rear slide part 34, the power supply to the electromagnet 311 of the electromagnet part 31 is cut off, the screws S are separated from the electromagnet part 31, and all the screws S are dropped on the scraper part 41 of the transport mechanism 4, The dropped screw S is loaded on the scraper unit 41 and is guided by the guide rail member 43 of the transport mechanism 4 to proceed to the subsequent steps.
Thereafter, the pumping mechanism 3 repeats the above-described process to repeat the pumping operation of the screw S as necessary.

[搬送機構4]
次に、搬送機構4を主に図13を参照して説明するが、公知の搬送機構4であるので、詳細な説明は省略するが、ネジSは汲取機構3から搬送機構4のスクレーパ部41に落下し、スクレーパ部41の案内レール部材43を底部とする傾斜する一対の羽根部411で案内され、羽根部411に連なる案内レール部材43に案内される。
このスクレーパ部41及び案内レール部材43は振動しネジSに前進するように作用する慣性力付与機構42より駆動され、この慣性力付与機構42は電磁コイル(ソレノイド)422に矩形波や交流を加電することによって、振動板423及び振動アーム431を介して案内レール部材43の全体が長手方向の前後に振動して、対向する案内レール部材43の隙間の嵌合レール溝44にネジSのボルト部が案内され、ネジSの頭部S2が嵌合レール溝44の溝の上に引っかかるように位置し、順次嵌合して整列して排出部6側に進行する。
[Conveyance mechanism 4]
Next, the transport mechanism 4 will be mainly described with reference to FIG. 13, but since it is a known transport mechanism 4, detailed description is omitted, but the screw S is removed from the scooping mechanism 3 to the scraper portion 41 of the transport mechanism 4. And is guided by a pair of inclined blade portions 411 having the guide rail member 43 of the scraper portion 41 as a bottom portion and guided by the guide rail member 43 connected to the blade portion 411.
The scraper portion 41 and the guide rail member 43 are driven by an inertial force applying mechanism 42 that vibrates and moves forward to the screw S. The inertial force applying mechanism 42 applies a rectangular wave or an alternating current to the electromagnetic coil (solenoid) 422. By electrifying, the entire guide rail member 43 vibrates back and forth in the longitudinal direction via the vibration plate 423 and the vibration arm 431, and the screw S of the screw S is inserted into the fitting rail groove 44 in the gap between the opposing guide rail members 43.

[ネジ取出装置7(カートリッジ取出し方式)]
前記排出部6にネジSを1本ずつ切り出して排出するが、これを取り出す取出し形態は、Sを1本ずつ所定位置に空気等で搬送するネジ取り出し方式、所定数をボックスに取り出すボックス取り出し方式、図17に示すように、供給装置を兼ねるカートリッジに整列して詰め込むカートリッジ取出し方式があるが、本実施例では、本発明者らが改良を加えたカートリッジ取出し方式を採用している。
このネジ取出し方式において、排出部6に設けたカートリッジステーション7は、カートリッジステーション7の固定部71の上面のベース部72が、ネジSに排出方向と直交する方向に交互にスライドシリンダー73で移動する構成で、左右に移動するベース部72の前面部721の排出口62に接する位置に、一方のカートリッジボックス74を置き、この一方のカートリッジボックス74のネジS挿入口741に整列しつつ切り出されたネジSを詰め込み、設定本数の詰め込みを完了したカートリッジボックス74を作業者がカートリッジステーション7のベース部72から取り出し、このカートリッジボックス74を作業する場所に移動する。
[Screw removal device 7 (cartridge removal system)]
The screw S is cut out and discharged one by one to the discharge unit 6, and the take-out form for taking out the screw S is a screw take-out method in which S is conveyed to a predetermined position by air or the like, and a box take-out method in which a predetermined number is taken out into a box As shown in FIG. 17, there is a cartridge take-out method in which the cartridge that also serves as the supply device is aligned and packed, but in this embodiment, the present inventors have adopted a cartridge take-out method that has been improved.
In this screw take-out method, in the cartridge station 7 provided in the discharge unit 6, the base portion 72 on the upper surface of the fixing unit 71 of the cartridge station 7 is moved by the slide cylinder 73 alternately in a direction perpendicular to the discharge direction with respect to the screw S. In the configuration, one cartridge box 74 is placed at a position in contact with the discharge port 62 of the front surface portion 721 of the base portion 72 that moves to the left and right, and is cut out while being aligned with the screw S insertion port 741 of this one cartridge box 74. The operator pulls out the cartridge box 74 that has been filled with the set number of screws S from the base portion 72 of the cartridge station 7 and moves the cartridge box 74 to a work place.

ここで、一方のカートリッジボックス74の取り出し移行を完了させると、他方のカートリッジボックス74のネジSの挿入口741を前記排出口62に接するようにスライドシリンダー73でセットし、ネジSのカートリッジボックス74の詰め込みを開始し、次の新たな空のカートリッジボックス74にネジSの詰め込み作業を行せるために、空のカートリッジボックス74を詰め込みを開始したカートリッジボックス74の横に並べてセットし、ネジSの次のカートリッジボックス74への詰め込み作業に備える。   Here, when the removal transfer of one cartridge box 74 is completed, the insertion port 741 of the screw S of the other cartridge box 74 is set by the slide cylinder 73 so as to contact the discharge port 62, and the cartridge box 74 of the screw S is set. In order to start the packing operation of the screw S into the next new empty cartridge box 74, the empty cartridge box 74 is set next to the cartridge box 74 which has started the packing, and the screw S In preparation for the next packing operation into the cartridge box 74.

次に、図18に示すように、別の実施例として、所定数のネジSを収納ボックス8に取り出すボックス取り出し方式を説明する。
この取り出し方式は、前記のカートリッジボックス取り出し方式のカートリッジボックス74に変えて、収納ボックス8を配置したもので、排出部6で所定数のネジSを取り出して、収納ボックス8に所定数のネジSを落下させて、作業する場所に移動する。
このボックス取り出し方式では、作業に必要な所定数のネジSが過不足無く収納ボックス8に収納されているので、使用者(作業者)は収納ボックス8にネジSが残っていれば、ネジSの締め忘れがあることに気付くことになる。
Next, as shown in FIG. 18, a box take-out method for taking out a predetermined number of screws S into the storage box 8 will be described as another embodiment.
In this take-out method, the storage box 8 is arranged in place of the cartridge box 74 of the above-described cartridge box take-out method, and a predetermined number of screws S are taken out by the discharge unit 6 and a predetermined number of screws S are taken into the storage box 8. Drop it and move it to the work place.
In this box take-out method, since a predetermined number of screws S required for the work are stored in the storage box 8 without excess or shortage, the user (operator) can remove the screws S if the screws S remain in the storage box 8. You will notice that you forgot to tighten.

以上のように、本発明のこれら実施例によれば、収納部2への上部からの電磁石部31の下降であるので、ネジS類を直接的に電磁石部31に吸着させることができ、強力に磁力をネジ類に作用させることができるので、大型の重量のあるネジSを吸着して移動することができ、収納部2さえ大容量にすれば供給回数を減らすことができる。
また、電磁石部31を採用することにより、金属ネジSの吸着と離反との制御が電源のON/OFFだけでよく、不必要な箇所でのネジ類の吸着も防げ、しかも簡単な構成が可能になり、力が加わらず自然にネジが落下するので、ネジに傷を与えることがなく、装置の部材の摩耗も少ないという作用を有する。
更に、電磁石部31の移動に長尺のチェーン部材32を用いることにより、大型の電磁石部31を垂直及び水平方向に移動することができ、設計の自由度を増すことができる。
なお、本発明の特徴を損なうものでなければ、前述した実施例に限定されないことは勿論である。
As described above, according to these embodiments of the present invention, since the electromagnet part 31 is lowered from the upper part to the storage part 2, the screws S can be directly attracted to the electromagnet part 31 and are powerful. Since the magnetic force can be applied to the screws, the large and heavy screw S can be attracted and moved, and the number of times of supply can be reduced if the storage unit 2 has a large capacity.
In addition, by adopting the electromagnet 31, it is only necessary to turn on and off the power supply to control the adsorption and separation of the metal screw S, and it is possible to prevent the adsorption of screws at unnecessary places, and a simple configuration is possible. Since the screw falls naturally without applying force, the screw is not damaged and the wear of the members of the apparatus is reduced.
Furthermore, by using the long chain member 32 to move the electromagnet portion 31, the large electromagnet portion 31 can be moved in the vertical and horizontal directions, and the degree of freedom in design can be increased.
Needless to say, the present invention is not limited to the above-described embodiments as long as the features of the present invention are not impaired.

ネジS類の移送に磁石を用いたので、磁性体であればネジS以外の類似形状の鋲・リベット等のネジ類等の用途にも適用できる。また、磁石に変えて真空吸引機構を取り付ければ、磁性体以外の真空吸着が可能な部材であれば、適用が可能である。   Since the magnet is used for transferring the screws S, the magnetic material can be applied to the use of screws such as hooks and rivets having similar shapes other than the screw S. In addition, if a vacuum suction mechanism is attached instead of a magnet, any member other than a magnetic material capable of vacuum suction can be applied.
