The second cover 72 on the rear end side is provided so as to cover the fan-shaped portion 63 side which is the end portion side. The first cover 71 is formed in a vertically long and substantially rectangular plate shape, and is arranged so as to mainly cover the housing 2 from the left and right lateral sides. The second cover 72 is formed in a plate shape and is arranged so as to cover the housing member 5 from the left and right lateral sides. In the closed state of the main lid 4 shown in FIG. 1, substantially the entire fan-shaped portion 63 is covered by the second cover 72, and in the opened state of the main lid 4 shown in FIG. 6, the inclined edge 63a side of the fan-shaped portion 63 becomes the second cover 72. To be covered.

また、図４に示すように、主蓋４には、長尺板状のストッパ７３が配置される。ストッパ７３は、軸受７３１に挿通された支持軸４５により回動可能に支持されており、ストッパ７３の下端縁に複数形成された矩形状の切欠部７３２をスリット２５２の内縁に係止させることにより、主蓋４の開状態を維持させることができる。また、スリット２５２と係止させる切欠部７３２を選択することにより、主蓋４の開状態の開角度を選択的に設定することができる。主蓋４を回動軸２９により開方向へ回動させると、ストッパ７３の切欠部７３２側が自重で下がり切欠部７３２とスリット２５２とを係止させることができる。そのため、主蓋４を開状態に自動的に固定させることができる。また、ストッパ７３の端部には操作片７３３が延設される。操作片７３３は、主蓋４のスリット４２１に挿通されて、主蓋４の外方へ突出している。主蓋４が開状態で固定されているときに、操作片７３３を下方に操作すると、切欠部７３２とスリット２５２との係止が解除されて主蓋４を閉方向に回動させることができる。このようにストッパ７３を用いて主蓋４の開状態の固定又は解除を容易に切り替えることができる。 Further, as shown in FIG. 4, a long plate-shaped stopper 73 is arranged on the main lid 4. The stopper 73 is rotatably supported by the support shaft 45 inserted through the bearing 731, and by locking a plurality of rectangular cutouts 732 formed at the lower end edge of the stopper 73 to the inner edge of the slit 252. The main lid 4 can be kept open. Further, by selecting the cutout portion 732 to be engaged with the slit 252, the open angle of the open state of the main lid 4 can be selectively set. When the main lid 4 is rotated in the opening direction by the rotation shaft 29, the notch 732 side of the stopper 73 is lowered by its own weight and the notch 732 and the slit 252 can be locked. Therefore, the main lid 4 can be automatically fixed in the open state. Further, an operation piece 733 is extended at the end of the stopper 73. The operation piece 733 is inserted into the slit 421 of the main lid 4 and projects to the outside of the main lid 4. When the operation piece 733 is operated downward while the main lid 4 is fixed in the open state, the engagement between the cutout portion 732 and the slit 252 is released, and the main lid 4 can be rotated in the closing direction. .. In this way, the stopper 73 can be used to easily switch between fixing and releasing the open state of the main lid 4.

次に、主蓋４の開閉動作について主に図５（ａ）、図５（ｂ）及び図６を用いて説明する。まず、主蓋４を閉状態から開状態へ操作するには、図５（ａ）に示すようにキャッチクリップ５１２と係止突起２５３ａの係止を解除して副蓋２５３の固定を解除する。副蓋２５３は自重によりヒンジ部２５４を中心に開方向へ回動する。副蓋２５３の固定が解除されると、主蓋４の閉状態の固定も解除される。 Next, the opening/closing operation of the main lid 4 will be described mainly with reference to FIGS. 5(a), 5(b) and 6. First, to operate the main lid 4 from the closed state to the open state, as shown in FIG. 5A, the catch clip 512 and the locking projection 253a are unlocked and the sub-cover 253 is unlocked. The sub lid 253 rotates in the opening direction about the hinge portion 254 by its own weight. When the fixing of the sub lid 253 is released, the fixing of the main lid 4 in the closed state is also released.

操作突起５１１を把持して主蓋４を開方向へ操作すると、主蓋４は自重による閉方向への閉じ力に抗して回動軸２９を中心に開方向へ回動する（図５（ｂ）参照）。このとき、モータ５ａの回転軸の駆動歯５ａ２と、スクリュー９の従動歯９２とにより構成される伝達機構の接続が離間して解除される。また、バリア部材６の回動軸受６３２には、主蓋４に対して固定された収容部材５の回動軸５２１,５３１が挿通されているため、バリア部材６の後端側は主蓋４の開方向への移動とともに上方へ引き上げられるように移動する。バリア部材６の前端側は、摺動突起６２１がスリット２３１，２４１に案内されながら上方へ移動する。従って、バリア部材６は、主蓋４の開方向へ回動とともに主蓋４のヒンジ部である回動軸２９側へ移動する。 When the operation protrusion 511 is gripped and the main lid 4 is operated in the opening direction, the main lid 4 rotates in the opening direction about the rotation shaft 29 against the closing force in the closing direction due to its own weight (see FIG. See b)). At this time, the connection of the transmission mechanism constituted by the drive tooth 5a2 of the rotating shaft of the motor 5a and the driven tooth 92 of the screw 9 is separated and released. Further, since the rotary shafts 521 and 531 of the housing member 5 fixed to the main lid 4 are inserted into the rotary bearing 632 of the barrier member 6, the rear end side of the barrier member 6 is located on the main lid 4 side. It moves so that it can be pulled upward as it moves in the opening direction. On the front end side of the barrier member 6, the sliding protrusion 621 moves upward while being guided by the slits 231 and 241. Therefore, the barrier member 6 moves toward the rotating shaft 29, which is the hinge portion of the main lid 4, as the main lid 4 rotates in the opening direction.

主蓋４をさらに開方向へ操作すると、図６の側面視において、バリア部材６は上縁６１ａが回動軸２９よりも上方に位置する程度にさらに上昇し、主蓋４やバリア部材６がスクリュー９の後方から上方側へ移動する（図４も参照）。したがって、スクリュー９の後方側の空間を広く確保することができる。また、図４に示すように、ストッパ７３の切欠部７３２を、スリット２５２に係止させることにより、主蓋４が閉方向へ回動しないように支持させておくことができる。よって、スクリュー９の挿抜などの作業を安全で容易に行うことができる。 When the main lid 4 is further operated in the opening direction, the barrier member 6 further rises to the extent that the upper edge 61a is located above the rotating shaft 29 in the side view of FIG. The screw 9 moves from the rear side to the upper side (see also FIG. 4). Therefore, a wide space on the rear side of the screw 9 can be secured. Further, as shown in FIG. 4, by locking the notch 732 of the stopper 73 in the slit 252, the main lid 4 can be supported so as not to rotate in the closing direction. Therefore, the work such as insertion/removal of the screw 9 can be performed safely and easily.

一方、図６の状態から図５（ｂ）の状態へ遷移するように、ストッパ７３を解除して、主蓋４を閉じていくと、摺動突起６２１がスリット２３１，２４１に案内されてバリア部材６が回動軸２９とは反対側の方向である下方へ下降する。したがって、主蓋４側の側板４４（４３）の前縁４４ａ（４３ａ）と、第一カバー７１の後縁７１ａ又は側板２８（２７）の後縁２８ａ（２７ａ）との間に、指等の障害物を入れても、下降するバリア部材６によりその障害物が下方へ排除されて、主蓋４とハウジング２の間に障害物が挟まれることを防止することができる。 On the other hand, when the stopper 73 is released and the main lid 4 is closed so that the state shown in FIG. 6 transits to the state shown in FIG. 5B, the sliding protrusion 621 is guided by the slits 231 and 241 to cause the barrier. The member 6 descends downward, which is the direction opposite to the rotating shaft 29. Therefore, between the front edge 44a (43a) of the side plate 44 (43) on the main lid 4 side and the rear edge 71a of the first cover 71 or the rear edge 28a (27a) of the side plate 28 (27), a finger or the like is provided. Even if an obstacle is put in, it can be prevented from being caught between the main lid 4 and the housing 2 by removing the obstacle downward by the descending barrier member 6.

また、バリア部材６の下縁６１ｂ（開口側の縁部）と、第一カバー７１の後縁７１ａ又はハウジング２の後縁２８ａ（２７ａ）（主蓋４側の縁部）との角度θを、略直角又は鈍角となるように設定することができる。したがって、バリア部材６の下縁６１ｂと、後縁７１ａ又は後縁２８ａ（２７ａ）と間により障害物を挟んでしまうことも防止できる。なお、バリア部材６の下縁６１ｂと、後縁７１ａ又は後縁２８ａ（２７ａ）の傾斜角度を適宜変更して、角度θを図５（ｂ）よりもさらに広角となるように設定できる。角度θは、主蓋４の開閉動作の移動中は常時鈍角となるよう設定することができる。 In addition, an angle θ between the lower edge 61b of the barrier member 6 (edge on the opening side) and the rear edge 71a of the first cover 71 or the rear edge 28a (27a) of the housing 2 (edge on the main lid 4 side) is defined as follows. , Can be set to be substantially right angle or obtuse angle. Therefore, it is possible to prevent the obstacle from being sandwiched between the lower edge 61b of the barrier member 6 and the rear edge 71a or the rear edge 28a (27a). The angle θ between the lower edge 61b of the barrier member 6 and the trailing edge 71a or the trailing edge 28a (27a) can be appropriately changed to set the angle θ to be wider than that in FIG. 5B. The angle θ can be set so that it is always an obtuse angle during the movement of the opening/closing operation of the main lid 4.

主蓋４をさらに閉方向へ回動させると、側板４３，４４の回動軸２９側の前縁４３ｂ，４４ｂと、後板２２の左右端側の一部とが当接して（図３参照）、主蓋４がハウジング２に対して閉じられる。このとき、モータ５ａの駆動歯５ａ２と、スクリュー９の従動歯９２とが歯合する。そして、副蓋２５３を閉じてキャッチクリップ５１２により固定することにより、主蓋４を閉状態に固定するとともに、駆動歯５ａ２と従動歯９２の駆動部の周囲の空間を外部から囲うように閉塞させることができ、スクリューフィーダ１を安全に使用することができる。 When the main lid 4 is further rotated in the closing direction, the front edges 43b and 44b of the side plates 43 and 44 on the rotation shaft 29 side and a part of the left and right end sides of the rear plate 22 come into contact with each other (see FIG. 3). ), the main lid 4 is closed with respect to the housing 2. At this time, the drive teeth 5a2 of the motor 5a and the driven teeth 92 of the screw 9 mesh with each other. Then, by closing the sub lid 253 and fixing it by the catch clip 512, the main lid 4 is fixed in the closed state, and the space around the drive portion of the drive tooth 5a2 and the driven tooth 92 is closed so as to surround it from the outside. Therefore, the screw feeder 1 can be used safely.

以上、本実施形態によると、ハウジング２と、ハウジング２に対して回動軸２９により回動可能に接続される主蓋４と、一端側が主蓋４に対して回動軸５２１，５３１により回動可能に接続され、他端側がハウジング２に対して摺動可能に案内されるバリア部材６と、を備えたスクリューフィーダ１について説明した。バリア部材６は、主蓋４の開方向への回動により主蓋４及びハウジング２の回動軸２９側へ移動し、主蓋４の閉方向への回動により回動軸２９と反対側へ移動するように形成される。 As described above, according to the present embodiment, the housing 2, the main lid 4 rotatably connected to the housing 2 by the turning shaft 29, and one end side of the main lid 4 rotated by the turning shafts 521 and 531. The screw feeder 1 including the barrier member 6 which is movably connected and whose other end side is slidably guided with respect to the housing 2 has been described. The barrier member 6 moves to the rotation shaft 29 side of the main lid 4 and the housing 2 by the rotation of the main lid 4 in the opening direction, and the side opposite to the rotation shaft 29 by the rotation of the main lid 4 in the closing direction. Is formed to move to.

ボックス構造の蓋の部分にヒンジ旋回型の開閉構造を用いた開閉装置の場合、蓋を閉じる際、蓋と本体との間で手を挟む等の事故を防止するために、ストッパ等によって蓋が閉まることを抑制する方法もあるが、誤った操作や、複数人で作業をする場合などでは、危険部位に手を入れたまま他の人が蓋を閉じてしまうなどの可能性も想定される。一方で、蓋の左右両側をバリア部材で覆うことによって危険部位に手が入らないようにする方法もあるが、開閉装置が小さい場合は作業スペースが十分に確保できず作業性が悪くなる。 In the case of an opening/closing device that uses a hinge swivel type opening/closing structure for the lid of the box structure, the lid is closed by a stopper to prevent accidents such as pinching hands between the lid and the main body when closing the lid. There is also a method to prevent it from being closed, but in the case of incorrect operation or when multiple people work, there is a possibility that other people may close the lid while putting their hands on the dangerous part. .. On the other hand, there is also a method of covering the left and right sides of the lid with barrier members to prevent the hands from getting into the dangerous area, but if the opening/closing device is small, the work space cannot be sufficiently secured and the workability deteriorates.

しかし本実施形態では、主蓋４やハウジング２を側方から覆う可動式のバリア部材６を設けたため、危険リスクを下げつつ作業性を低下させない構成とすることができる。そして、主蓋４を閉じる際はバリア部材６により指等の障害物をワイピング動作で押しのけて、事故を防ぐことができる。 However, in this embodiment, since the movable barrier member 6 that covers the main lid 4 and the housing 2 from the side is provided, it is possible to reduce the risk of danger and the workability. When the main lid 4 is closed, the barrier member 6 pushes an obstacle such as a finger away by a wiping operation to prevent an accident.

また、副蓋２５３は、主蓋４が開状態のときには主蓋４とは反対方向に開いて開状態となるため、作業性を低下させないように構成される。また、副蓋２５３は、主蓋４を閉じた後に、主蓋４に対してロックされるため主蓋４とハウジング２との間の隙間を埋めて指等の挿入を防止することができる。 Further, the sub lid 253 is configured so as not to reduce workability because the sub lid 253 is opened in the opposite direction to the main lid 4 when the main lid 4 is in the open state and is in the open state. Further, since the sub lid 253 is locked with respect to the main lid 4 after the main lid 4 is closed, it is possible to fill the gap between the main lid 4 and the housing 2 and prevent the insertion of fingers or the like.

以上、本発明の実施形態を説明したが、本発明は実施形態により限定されることは無く、種々の変更を加えて実施することができる。例えば、本実施形態では、スクリュー９や流路Ｐを収容するハウジング２と、このハウジング２に対して回動軸２９により開閉する主蓋４と、を備えたスクリューフィーダ１について説明したが、主蓋４とハウジング２には、本実施形態で説明したスクリューフィーダ１とは異なる機能や構造を設けて他の用途に用いられる開閉装置を構成してもよい。 Although the embodiment of the present invention has been described above, the present invention is not limited to the embodiment and can be implemented with various modifications. For example, in the present embodiment, the screw feeder 1 including the housing 2 that accommodates the screw 9 and the flow path P, and the main lid 4 that opens and closes with respect to the housing 2 by the rotation shaft 29 has been described. The lid 4 and the housing 2 may be provided with functions and structures different from those of the screw feeder 1 described in the present embodiment to configure an opening/closing device used for other purposes.

例えば、主蓋４、ハウジング２及びバリア部材６を開閉扉に適用させてもよい。この場合、ハウジング２は扉の枠体とし、主蓋４をハウジング２対してヒンジ部を介して回動可能な扉として配置して、扉の閉状態では枠体内の空間を遮蔽して人や物の出入りを規制し、扉の開状態では枠体内の空間を開口させて人や物の出入りを可能とするように切り替えることができる。また、扉と枠体とのヒンジ部を覆うように、本実施形態で説明したバリア部材６と同様にヒンジ部に対して遠近移動可能なバリア部材を設けることができる。 For example, the main lid 4, the housing 2, and the barrier member 6 may be applied to the opening/closing door. In this case, the housing 2 is a door frame, and the main lid 4 is arranged as a door that is rotatable with respect to the housing 2 via a hinge portion. It is possible to regulate the entry and exit of the object, and open the space in the frame body in the opened state of the door to switch the entry and exit of people and objects. Further, a barrier member that can move far and far with respect to the hinge portion can be provided so as to cover the hinge portion between the door and the frame body, similarly to the barrier member 6 described in the present embodiment.

また、本実施形態において、バリア部材６は主蓋４の閉方向への移動のときに自重によりヒンジ部である回動軸２９とは反対側へ移動したが、バリア部材６はコイルばね等の弾性部材により回動軸２９とは反対側へ付勢されており主蓋４の閉方向への移動のときにその弾性部材の弾発力により回動軸２９とは反対側へ移動する構成としてもよい。従って、主蓋４の開方向は、本実施形態とは逆の下方向や水平方向等の他の方向となるように開閉装置の機能に応じて適宜構成することができる。 Further, in the present embodiment, the barrier member 6 moves to the side opposite to the pivot shaft 29 which is the hinge portion due to its own weight when the main lid 4 moves in the closing direction, but the barrier member 6 is a coil spring or the like. The elastic member is urged to the side opposite to the rotating shaft 29, and when the main lid 4 moves in the closing direction, the elastic force of the elastic member moves to the side opposite to the rotating shaft 29. Good. Therefore, the opening direction of the main lid 4 can be appropriately configured according to the function of the opening/closing device such that the main cover 4 is opened in the other direction, such as the downward direction or the horizontal direction, which is the reverse of the present embodiment.

また、バリア部材６の一端側を、ハウジング２に対して回動軸により回動可能に接続され、バリア部材６の他端側を、主蓋４に対して摺動可能に案内させる構成としてもよい。 Alternatively, one end of the barrier member 6 may be rotatably connected to the housing 2 by a rotation shaft, and the other end of the barrier member 6 may be slidably guided with respect to the main lid 4. Good.
