Description
本発明は、単一のコンベアの搬送面上に搬送面スペースを有効に利用して最大限にワークを貯蔵できるようにした、単一コンベアによるワーク一時貯蔵方法に関するものである。 The present invention relates to a method of temporarily storing a work by a single conveyor, which can effectively store a work surface on a transport surface of a single conveyor so that the work can be stored to the maximum extent.
乾式粉末成形装置は、水などの液体を圧力媒体とし、圧力容器内においてゴム型を介して粉体に通常１００ＭＰａ以上の高い等方圧力を加えて、粉体を種々の形状に成形する装置であり、セラミックスや粉末冶金の分野で広く用いられている。 A dry powder molding apparatus is an apparatus that uses a liquid such as water as a pressure medium and applies a high isotropic pressure of 100 MPa or more to the powder through a rubber mold in a pressure vessel to form the powder into various shapes. Yes, it is widely used in the field of ceramics and powder metallurgy.
この乾式粉末成形装置を備えた粉末成形品の製造ラインでは、乾式粉末成形装置の成形サイクル毎に、ワーク把持装置５２により、ワーク（成形品）５１を乾式粉末成形装置から取り出し、コンベア５３まで搬送し、図４に示すように、停止中のコンベア５３の搬送面上に載置することで、この単一のコンベア５３の搬送面上にワークを搬送面スペースの範囲内で一時的に貯蔵するようにしている。 In a powder molded product production line equipped with this dry powder molding device, a workpiece (molded product) 51 is taken out of the dry powder molding device by a workpiece gripping device 52 and conveyed to a conveyor 53 for each molding cycle of the dry powder molding device. Then, as shown in FIG. 4, the work is temporarily stored on the transport surface of the single conveyor 53 within the space of the transport surface by being placed on the transport surface of the stopped conveyor 53. I am doing so.
この場合、ワーク把持装置により、1つずつワークをコンベア５３の始端部位置の搬送面上に載置する際に、前回載置されたワークと今回載置するワークとが干渉して載置作業の邪魔にならないようにする必要がある。そのため、予め、前回に載置されたワークは、搬送面上に載置された後、コンベア５３を駆動して搬送面をコンベア始端部とは反対の方向へ所定距離だけ走行させて、ワーク把持装置５２の作業範囲外まで移動されるようになっている。 In this case, when the workpieces are placed one by one on the transport surface at the start end position of the conveyor 53 by the workpiece gripping device, the workpiece placed last time interferes with the workpiece placed this time. It is necessary not to get in the way. For this reason, the work previously placed in advance is placed on the transport surface, and then the conveyor 53 is driven to run the transport surface in a direction opposite to the conveyor start end by a predetermined distance to grip the work. The device 52 is moved out of the working range.
このように、従来の単一コンベアによるワーク一時貯蔵方法では、コンベアの搬送面上に貯蔵されるワーク間に大きな間隔距離が発生するものであった。このため、所定数のワークを一時貯蔵するために長尺のコンベアが必要で大きな設置スペースも必要となり、成形製品の生産量の増大にスムーズに対応できなかった。 Thus, in the conventional work temporary storage method using a single conveyor, a large distance is generated between the works stored on the transport surface of the conveyor. For this reason, in order to temporarily store a predetermined number of works, a long conveyor is required and a large installation space is also required, and it has not been possible to smoothly cope with an increase in the production amount of molded products.
なお従来、互いに連携して運転される複数のコンベアによるワーク一時貯蔵方法に関連する従来技術としては、例えば特開平５−１２４７２１号公報によるものが提案されている。
そこで本発明は、他コンベアとの連携なく単独運転される単一のコンベアの搬送面上に、1つずつ載置されるワークを順次貯えて一時的に貯蔵するに際し、それまでに貯蔵されている一時貯蔵中のワークと今回載置するワークとの干渉をなくして載置作業の邪魔にならないようにできるとともに、搬送面スペースを有効に利用して最大限にワークを貯蔵できるようにした、単一コンベアによるワーク一時貯蔵方法を提供することをその課題とする。 Therefore, in the present invention, when the workpieces placed one by one are sequentially stored and temporarily stored on the transport surface of a single conveyor that is independently operated without cooperation with other conveyors, The work that is temporarily stored and the work to be placed this time can be prevented from interfering with the work to be placed, and the work surface can be effectively used to store the work as much as possible.

以下、図面を参照して本発明の実施の形態について説明する。図１は本発明の一実施形態による単一コンベアによるワーク一時貯蔵方法の実施に用いられる装置の概略構成を示す平面図、図２は図１の側面図である。 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing a schematic configuration of an apparatus used for carrying out a method for temporarily storing workpieces by a single conveyor according to an embodiment of the present invention, and FIG. 2 is a side view of FIG.
図１及び図２において、１はワーク一時貯蔵用コンベア（以下、単にコンベアともいう）であり、乾式粉末成形装置で成形された成形品（ワーク）を一時的に貯蔵するためのものである。コンベア１は、フレーム３，３の一端（始端）に取り付けた駆動プーリ４と、フレーム３，３の他端（終端）に取り付けたテールプーリ５とによってベルト２を巻装し、ベルト２を無端回転させるものである。駆動プーリ４には、コンベア１の駆動、停止を行うモータ６が連結されている。コンベア１は正逆駆動可能となっている。このコンベア１の図における左側の始端位置には、ベルト２の搬送面上を横切るように当接板７が配置されている。また、コンベア１の図における右側の終端位置には、板状のストッパ８が配置されている。 1 and 2, reference numeral 1 denotes a workpiece temporary storage conveyor (hereinafter, also simply referred to as a conveyor), which temporarily stores a molded product (work) formed by a dry powder molding apparatus. The conveyor 1 winds the belt 2 with a drive pulley 4 attached to one end (starting end) of the frames 3 and 3 and a tail pulley 5 attached to the other end (terminal) of the frames 3 and 3, and rotates the belt 2 endlessly. It is something to be made. A motor 6 that drives and stops the conveyor 1 is connected to the drive pulley 4. The conveyor 1 can be driven forward and backward. An abutment plate 7 is disposed at the starting end position on the left side of the conveyer 1 so as to cross the conveying surface of the belt 2. A plate-like stopper 8 is disposed at the right end position of the conveyor 1 in the drawing.
そして、コンベア１に対して、当接板７を起点としてベルト搬送面の走行方向に沿って順にワーク受取り領域位置Ａ１とワーク一時貯蔵領域位置Ａ２とが設定されている。後述するように、図示しないワーク把持装置により、図１に示すように、ワーク受取り領域位置Ａ１に対応するベルト搬送面上の中央部に、矩形のワークが搬送面の走行方向と直交する方向に延びる姿勢で水平に載置されるようになっている。このワーク受取り領域位置Ａ１の中央に、コンベア１を挟むようにようにして第１のワーク検出センサ９が配置されている。第１のワーク検出センサ９は、ワーク受取り領域位置Ａ１に対応するベルト搬送面上にワークが載置されたことを検出するためのものである。第１のワーク検出センサ９は、発光器９ａと、この発光器９ａからの光がワークによって遮られることを検出する受光器９ｂとからなる透過型光電スイッチで構成されている。 For the conveyor 1, a workpiece receiving area position A1 and a workpiece temporary storage area position A2 are set in order along the traveling direction of the belt conveying surface with the contact plate 7 as a starting point. As will be described later, by a workpiece gripping device (not shown), as shown in FIG. 1, a rectangular workpiece is placed in a direction perpendicular to the traveling direction of the conveying surface at the center on the belt conveying surface corresponding to the workpiece receiving area position A1. It is placed horizontally in an extended posture. A first work detection sensor 9 is arranged at the center of the work receiving area position A1 so as to sandwich the conveyor 1 therebetween. The first workpiece detection sensor 9 is for detecting that a workpiece is placed on the belt conveyance surface corresponding to the workpiece receiving area position A1. The first workpiece detection sensor 9 includes a transmissive photoelectric switch including a light emitter 9a and a light receiver 9b that detects that the light from the light emitter 9a is blocked by the workpiece.
また、後述するように、前記ワーク一時貯蔵領域位置Ａ２に対応するベルト搬送面上には、図１に示すように、ワークが貯えられて一時貯蔵されるようになっている。このワーク一時貯蔵領域位置Ａ２の始端（ワーク一時貯蔵領域位置Ａ２における当接板７側端）には、コンベア１を挟むようにようにして第２のワーク検出センサ１０が配置されている。この第２のワーク検出センサ１０は、発光器１０ａと受光器１０ｂとからなる透過型光電スイッチで構成されている。さらに、このワーク一時貯蔵領域位置Ａ２の終端（ワーク一時貯蔵領域位置Ａ２における反当接板７側端）には、コンベア１を挟むようにようにして、発光器１１ａと受光器１１ｂとからなる透過型光電スイッチで構成される第３のワーク検出センサ１１が配置されている。 Further, as will be described later, the work is stored and temporarily stored on the belt conveying surface corresponding to the work temporary storage area position A2, as shown in FIG. A second workpiece detection sensor 10 is disposed at the starting end of the workpiece temporary storage area position A2 (the contact plate 7 side end at the workpiece temporary storage area position A2) so as to sandwich the conveyor 1 therebetween. The second workpiece detection sensor 10 includes a transmissive photoelectric switch including a light emitter 10a and a light receiver 10b. Further, at the end of the work temporary storage area position A2 (the end on the side opposite to the abutting plate 7 at the work temporary storage area position A2), a light emitter 11a and a light receiver 11b are arranged so as to sandwich the conveyor 1. A third workpiece detection sensor 11 composed of a transmissive photoelectric switch is disposed.
また、シーケンサからなる図示しない制御装置が備えられており、この制御装置は、ワーク検出センサ９，１０，１１からの検出信号に基づいてモータ６の駆動回路に信号を送って、コンベア１の駆動、停止を制御するようになっている。 Further, a control device (not shown) composed of a sequencer is provided. This control device sends a signal to the drive circuit of the motor 6 on the basis of detection signals from the workpiece detection sensors 9, 10, and 11 to drive the conveyor 1. It comes to control the stop.
次に、本実施形態のワーク一時貯蔵方法について、図３を参照しながら説明する。図３は本発明のワーク一時貯蔵方法を説明するための図であって、その（ａ）は第１工程の説明図、その（ｂ）は第２工程の説明図、その（ｃ）は第３工程の説明図である。 Next, the work temporary storage method of this embodiment will be described with reference to FIG. FIG. 3 is a diagram for explaining the work temporary storage method of the present invention, in which (a) is an explanatory diagram of the first step, (b) is an explanatory diagram of the second step, and (c) is the first diagram. It is explanatory drawing of 3 processes.
まず、図３（ａ）を参照しながら第１工程について説明する。なおここでは、最初（１つ目）のワークに対するワーク一時貯蔵処理動作が完了し、停止中のコンベア１のワーク一時貯蔵領域位置Ａ２に対応するベルト搬送面上に、前記最初のワークである１個の一時貯蔵中ワークＷｏ（ｏ：ｏｌｄ）が貯えられているものとする。さて、図示しないワーク把持装置により、ワーク受取り領域位置Ａ１に対応するベルト搬送面上に１個の新たなワークＷｎ（ｎ：ｎｅｗ）が載置されると、このことが第１のワーク検出センサ９によって検出される。 First, the first step will be described with reference to FIG. Here, the workpiece temporary storage processing operation for the first (first) workpiece is completed, and the first workpiece is 1 on the belt conveyance surface corresponding to the workpiece temporary storage area position A2 of the conveyor 1 being stopped. It is assumed that the workpiece Wo (o: old) during temporary storage is stored. When a new workpiece Wn (n: new) is placed on the belt conveyance surface corresponding to the workpiece receiving area position A1 by a workpiece gripping device (not shown), this is the first workpiece detection sensor. 9 is detected.
次に、図３（ｂ）を参照しながら第２工程について説明する。第１工程で新たなワークＷｎが載置されたことが検出されると、コンベア１を逆転駆動してそのベルト搬送面を当接板７の側の方向へ走行させる。そして、新たなワークＷｎと、ワーク一時貯蔵領域位置Ａ２に対応する搬送面上に貯えられていた前記一時貯蔵中ワークＷｏとは、当接板７によって移動を阻止されてその距離が詰められ、隙間無しで整列させられて１つのワーク群として纏められる。この場合、ベルト２の走行速度は、当接板７とワークＷｎとの接触や、ワークＷｎ，Ｗｏ同士の接触による衝撃を抑制できる低速度に設定されている。そして、ワークＷｎ，Ｗｏが隙間無しで整列した１つのワーク群として纏められると、コンベア１の駆動が一時停止される。この実施形態では、コンベア１の前記逆転駆動からこの一時停止までの時間は、予めタイマで設定されるようになっている。 Next, the second step will be described with reference to FIG. When it is detected that a new work Wn is placed in the first step, the conveyor 1 is driven in reverse to run the belt conveying surface in the direction toward the contact plate 7. Then, the new workpiece Wn and the temporary storage workpiece Wo stored on the transport surface corresponding to the workpiece temporary storage area position A2 are blocked from moving by the contact plate 7, and the distance is reduced. Aligned with no gaps and grouped together as one work group. In this case, the traveling speed of the belt 2 is set to a low speed that can suppress the impact caused by the contact between the contact plate 7 and the workpiece Wn or the contact between the workpieces Wn and Wo. Then, when the workpieces Wn and Wo are grouped as one workpiece group aligned without a gap, the driving of the conveyor 1 is temporarily stopped. In this embodiment, the time from the reverse rotation driving of the conveyor 1 to this temporary stop is set in advance by a timer.
次に、図３（ｃ）を参照しながら第３工程について説明する。次に、コンベア１を正転駆動してそのベルト搬送面を当接板７の側と反対方向へ走行させる。そして、隙間無しで整列したワークＷｎ，Ｗｏからなる一纏まりのワーク群のうちの走行方向に関して最後尾のワークであるワークＷｎが、ワーク一時貯蔵領域位置Ａ２に対応する搬送面上に到達すると、このことが第２のワーク検出センサ１０によって検出される。この実施形態では、第２のワーク検出センサ１０において受光器１０ｂが発光器１０ａからの光が一旦遮られた後に再度入射することで、最後尾のワークＷｎがワーク一時貯蔵領域位置Ａ２に対応する搬送面上に到達したと判断するようにしている。この最後尾のワークＷｎの到達を検出すると、コンベア１の駆動が停止される。なお、この場合、コンベア１の前記正転駆動開始からその停止までを、予めタイマで時間設定して行うようにしてもよい。ここで、前述した最後尾のワークＷｎの判断に際し、第２のワーク検出センサ１０において受光器１０ｂが発光器１０ａからの光が一旦遮られた後に再度入射すると、タイマによる計時を開始し、予め定められた設定時間の経過後に、コンベア１の駆動を停止するようにしてもよい。これにより、何らかの理由でワーク間に隙間が生じた場合に、最後尾のワークＷｎがワーク一時貯蔵領域位置Ａ２に対応する搬送面上に到達する前にコンベア１の駆動が停止されることを回避することができる。 Next, the third step will be described with reference to FIG. Next, the conveyor 1 is driven to rotate forward so that the belt conveyance surface travels in the direction opposite to the contact plate 7 side. Then, when the workpiece Wn which is the last workpiece in the traveling direction among the group of workpieces composed of the workpieces Wn and Wo aligned without a gap reaches the conveyance surface corresponding to the workpiece temporary storage area position A2, This is detected by the second workpiece detection sensor 10. In this embodiment, in the second workpiece detection sensor 10, the light receiver 10b is incident again after the light from the light emitter 10a is interrupted, so that the last workpiece Wn corresponds to the workpiece temporary storage area position A2. It is determined that it has reached the conveyance surface. When the arrival of the last workpiece Wn is detected, the driving of the conveyor 1 is stopped. In this case, the time from the start of the forward rotation drive to the stop of the conveyor 1 may be set in advance with a timer. Here, in determining the last workpiece Wn described above, when the light receiver 10b in the second workpiece detection sensor 10 is incident again after the light from the light emitter 10a is once interrupted, the time measurement by the timer is started. You may make it stop the drive of the conveyor 1 after progress of the defined setting time. This prevents the drive of the conveyor 1 from being stopped before the last workpiece Wn reaches the conveyance surface corresponding to the workpiece temporary storage area position A2 when a gap is generated between the workpieces for some reason. can do.
このような第１工程から第３工程までからなるワーク一時貯蔵処理動作が繰り返される。そして、隙間無しで整列した一纏まりのワーク群のうちの走行方向に関して最前列のワークが、ワーク一時貯蔵領域位置Ａ２の前記終端位置に到達すると、このことが第３のワーク検出センサ１１によって検出されて、コンベア１の駆動が停止される。同時に、ワーク一時貯蔵領域位置Ａ２に対応する搬送面上のワークが満載状態である旨がディスプレイ表示され、あるいは音声報知されるようになっている。なお、ストッパ８は、第３のワーク検出センサ１１などの故障による満載状態のワークのコンベア１からの万が一の落下を防止するためのものである。このようにしてコンベア１に一時的に貯えられたワークは、例えば人手により、次の機械加工工程に送られることとなる。 The workpiece temporary storage processing operation including the first to third steps is repeated. Then, when the work in the foremost row in the group of work groups arranged without gaps reaches the terminal position of the work temporary storage area position A2, this is detected by the third work detection sensor 11. Thus, the driving of the conveyor 1 is stopped. At the same time, the fact that the work on the transport surface corresponding to the work temporary storage area position A2 is in a full state is displayed on the display or is notified by voice. Note that the stopper 8 is for preventing an accidental drop from the conveyor 1 of a fully loaded workpiece due to a failure of the third workpiece detection sensor 11 or the like. The workpieces temporarily stored in the conveyor 1 in this way are sent to the next machining process, for example, manually.
このように、本実施形態のワーク一時貯蔵方法は、コンベア１のワーク受取り領域位置Ａ１に対応する搬送面上にワークＷｎが載置される際に、それまでに貯蔵されている一時貯蔵中ワークＷｏがコンベア１のワーク一時貯蔵領域位置Ａ２に対応する搬送面上に位置しているようにしている。よって、単一のコンベア１の搬送面上に、1つずつ載置されるワークＷｎを順次貯えて一時的に貯蔵するに際し、前回までに載置された一時貯蔵中ワークＷｏと今回新たに載置するワークＷｎとの干渉をなくして載置作業の邪魔にならないようにすることができる。 As described above, the workpiece temporary storage method according to the present embodiment is a temporary storage workpiece that has been stored so far when the workpiece Wn is placed on the transport surface corresponding to the workpiece receiving area position A1 of the conveyor 1. Wo is positioned on the conveying surface corresponding to the workpiece temporary storage area position A2 of the conveyor 1. Therefore, when the workpieces Wn placed one by one are sequentially stored and temporarily stored on the transport surface of the single conveyor 1, the temporarily stored workpiece Wo placed up to the previous time and this time newly placed. The interference with the workpiece Wn to be placed can be eliminated so as not to interfere with the placement work.
また、搬送面上に載置された新たなワークＷｎと、それまでに貯蔵されている一時貯蔵中ワークＷｏとをその距離を詰めて隙間無しで整列させてなる１つのワーク群を形成し、しかる後、この１つのワーク群をコンベア１のワーク一時貯蔵領域位置Ａ２に対応する搬送面上に位置させて貯えるようにしている。よって、単一のコンベア１の搬送面上に、1つずつ載置されるワークを順次貯えて一時的に貯蔵するに際し、従来方法とは違って、搬送面スペースを有効に利用して最大限にワークを貯蔵することができる。 Further, to form a new workpiece Wn placed on the conveying surface, one work group and temporarily stores in the work Wo which is stored until it filled its length becomes align without gaps, Thereafter, this one work group is positioned and stored on the transport surface corresponding to the work temporary storage area position A2 of the conveyor 1. Therefore, when sequentially storing workpieces placed one by one on the transport surface of a single conveyor 1 and storing them temporarily, the space on the transport surface is effectively used and maximized. Can store workpieces.
