Description

板材収納装置Board storage device
　この発明は、孔あけや成形加工などが行われたドア部材などの板材を積載して収納するとともに、組立装置や梱包作業に板材を供給する板材収納装置に関するものである。 The present invention relates to a plate material storage device that stacks and stores plate materials such as door members that have been subjected to drilling or forming processing, and that supplies the plate material to an assembling apparatus or packaging work.
　パンチプレスやレーザ加工機などの板材加工機に対して供給する板状のワークの搬入、供給を行うと共に、前記板材加工機によって加工された製品を搬出して格納するために板材収納装置が用いられる。 A plate material storage device is used to carry in and supply a plate-shaped workpiece to be supplied to a plate material processing machine such as a punch press or a laser processing machine, and to carry out and store a product processed by the plate material processing machine. It is done.
　この板材収納装置としては、従来、板材加工機に隣接して備えられた棚装置が知られている。この種の棚装置は、例えば、パレットを格納（収容）する収容棚を複数段備えた棚本体の前側に、前記各収容棚に対してパレットの出入りを行うエレベータ装置を上下動自在に備え、前記棚本体の後側に、パレット上に積載されている板状のワークの１枚取りを行う１枚取り装置を備えている。そして、前記棚本体の下部には、板材加工機に対してワークの搬入を行うと共に、板材加工機から加工後の製品の搬出を行うためのワーク搬入装置を備えた構成が一般的である（例えば、特許文献１参照）。 As this plate material storage device, a shelf device provided adjacent to a plate material processing machine is conventionally known. This type of shelf device includes, for example, an elevator device that allows a pallet to enter and exit from the front side of a shelf body that includes a plurality of storage shelves for storing (accommodating) pallets, and is movable up and down. On the rear side of the shelf main body, there is provided a single picking device that picks up a single plate-shaped workpiece loaded on the pallet. And the structure provided with the workpiece carrying-in apparatus for carrying out the workpiece | work carrying out with respect to a board | plate material processing machine and carrying out the processed product from a board | plate material processing machine is common at the lower part of the said shelf main body ( For example, see Patent Document 1).
　上記した棚装置においては、パレットの出入りを行う専用のエレベータ装置が必要となり、装置が大型化し、また、コストが嵩む等の難点がある。 In the above-described shelf device, a dedicated elevator device for entering and exiting the pallet is necessary, and there are problems such as an increase in size of the device and an increase in cost.
　棚の出し入れのための専用の装置を不要にした板材収納システムが提案されている（例えば、特許文献２参照）。この板材収納システムに用いられる板材ストッカにつき、図面を参照して説明する。 A plate material storage system that eliminates the need for a dedicated device for taking in and out of a shelf has been proposed (for example, see Patent Document 2). A plate stocker used in this plate material storage system will be described with reference to the drawings.
　図２３及び図２４に示すように、板材ストッカ１５０は、基台１５０の一端部に立設された立フレーム１５１を有し、この立フレーム１５１に複数段の棚１５２が跳ね上げ自在に設けられている。各段の棚１５２は、その基端の両側部が、立フレーム１５１から横向きに突出する左右一対の支持片１５３にヒンジ１５２ａで支持されることで、使用位置である水平位置と退避位置である跳ね上がった傾斜位置との間に回動自在とされている。 As shown in FIGS. 23 and 24, the plate stocker 150 has a standing frame 151 erected on one end of a base 150, and a plurality of stages of shelves 152 are provided on the standing frame 151 so as to be freely raised. ing. The shelf 152 of each stage has a horizontal position and a retracted position, which are used positions, by supporting both sides of the base end thereof with a pair of left and right support pieces 153 protruding laterally from the standing frame 151 by hinges 152a. It is possible to rotate between the inclined position where it jumps up.
　前記支持片１５３には、図２５及び図２６に示すように、棚１５２を水平姿勢に受け止めて保持する水平ストッパ１５３ａと、傾斜姿勢に受け止めて保持する傾斜ストッパ１５３ｂとがそれぞれ設けられている。 25 and 26, the support piece 153 is provided with a horizontal stopper 153a for receiving and holding the shelf 152 in a horizontal posture and an inclination stopper 153b for receiving and holding the shelf 152 in an inclined posture.
　また、各棚１５２の両側部のヒンジ１５２ａに近接した位置と、各棚１５２に対応する前記支持片１５３の中間位置とは、例えば、引っ張りコイルばねからなる棚位置規制手段１５４で連結されている。棚位置規制手段１５４は、棚１５２を使用位置である水平位置と、跳ね上げられた退避位置との２位置の規制する手段である。 Further, the positions close to the hinges 152a on both sides of each shelf 152 and the intermediate position of the support piece 153 corresponding to each shelf 152 are connected by a shelf position restricting means 154 made of, for example, a tension coil spring. . The shelf position restricting means 154 is a means for restricting the shelf 152 at two positions, ie, a horizontal position that is a use position and a retreated position that is flipped up.
　引っ張りコイルばね１５４の中心線は、図２５のように、棚１５２が傾斜ストッパ１５３ｂに受け止められて跳ね上がった退避位置にある状態でヒンジ１５２ａの回転中心より上側に位置し、図２６のように、棚１５２が水平ストッパ１５３ａに受け止められた使用位置にある状態でヒンジ１５２ａの回転中心より下側に位置するようにされている。これにより、引っ張りコイルばね１５４の中心線がヒンジ１５２ａの中心より上側に移動するまで棚１５２が跳ね上がると、引っ張りコイルばね１５４の引っ張り力が棚１５２を傾斜ストッパ１５３ｂに押し付け、また、引っ張りコイルばね１５４の中心線が前記ヒンジ１５２ａの中心より下側に移動するまで棚１５２が水平姿勢側に回動すると、引っ張りコイルばね１５４の引っ張り力が棚１５２を水平ストッパ１５３ｂに押し付けるように構成されている。 As shown in FIG. 25, the center line of the tension coil spring 154 is located above the rotation center of the hinge 152a in a state where the shelf 152 is received by the inclined stopper 153b and is in a retracted position, as shown in FIG. The shelf 152 is positioned below the center of rotation of the hinge 152a in the use position received by the horizontal stopper 153a. Thus, when the shelf 152 jumps up until the center line of the tension coil spring 154 moves upward from the center of the hinge 152a, the tension force of the tension coil spring 154 presses the shelf 152 against the inclined stopper 153b, and the tension coil spring 154 When the shelf 152 rotates to the horizontal posture side until the center line of the hinge 152a moves downward from the center of the hinge 152a, the pulling force of the tension coil spring 154 presses the shelf 152 against the horizontal stopper 153b.
　板材Ｍは、搬出入用ロボットアーム等を用いて板材ストッカ１５０から取り出し、または収納させる。板材Ｍをストッカ１５０から取り出す時や収納させる時には、棚１５２の水平位置と退避位置との切換えが行われる。この切り替えは、搬出入用ロボットアーム等で、棚５２を退避位置側から使用位置側へ、または使用位置側から退避位置側へ押すことにより行われる。 The plate material M is taken out from or stored in the plate material stocker 150 using a carrying-in / out robot arm or the like. When the plate material M is taken out from the stocker 150 or stored, the horizontal position of the shelf 152 and the retreat position are switched. This switching is performed by pushing the shelf 52 from the retracted position side to the used position side or from the used position side to the retracted position side by a carrying-in / out robot arm or the like.
　次に、上記の装置の動作について説明する。図示しない板材加工機で加工された板材製品Ｍは、搬出入用ロボットアームの吸着パッドで吸着して搬出される。この搬出に先立ち、搬出入用ロボットアームが板材ストッカ１５０において、図２４のように各棚１５２が跳ね上がり姿勢である退避位置にある棚１５２のうち、最下段の棚１５２を鎖線で示すように水平姿勢である使用位置に切り換える。その位置切換えは、搬出入用ロボットアームで棚１５２の先端を使用位置側に押すことにより行われる。 Next, the operation of the above apparatus will be described. A plate product M processed by a plate processing machine (not shown) is sucked and carried out by a suction pad of a carry-in / out robot arm. Prior to this unloading, the loading / unloading robot arm in the plate stocker 150 is horizontal as shown by the chain line in the lowermost shelf 152 of the shelves 152 in the retracted position in which each shelf 152 is in the jumping position as shown in FIG. Switch to the use position that is the posture. The position is switched by pushing the tip of the shelf 152 to the use position side by the carry-in / out robot arm.
　すなわち、退避位置にある棚５２は、図２５のように、引っ張りコイルばね１５４で傾斜ストッパ１５３ｂに押し付けられて退避位置に保持されているが、棚１５２が搬出入用ロボットアームで使用位置側に押されて、引っ張りコイルばね５４の中心線が棚ヒンジ１５２ａの中心より下側に移動すると、棚１５２は引っ張りコイルばね１５４の引っ張り力で水平ストッパ１５３ａに押し付けられて、図２６のように、水平姿勢となる使用位置に保持される。この使用位置の棚１５２の上に、搬出入用ロボットアームで搬出された板材製品Ｍが載置される。 That is, as shown in FIG. 25, the shelf 52 in the retracted position is pressed against the inclined stopper 153b by the tension coil spring 154 and held in the retracted position, but the shelf 152 is moved to the use position side by the loading / unloading robot arm. When pushed, the center line of the tension coil spring 54 moves downward from the center of the shelf hinge 152a, the shelf 152 is pressed against the horizontal stopper 153a by the tension force of the tension coil spring 154, and as shown in FIG. It is held at the use position that becomes the posture. On the shelf 152 at the use position, the plate material product M carried out by the carrying-in / out robot arm is placed.
　板材製品Ｍを載置した搬出入用ロボットアームは、板材製品Ｍを載置した棚１５２の上段の棚１５２を、先の場合と同様に、退避位置から使用位置に切り換えてから、次の板材製品Ｍを板材加工機に取りに行く。このようにして、板材ストッカ１５０の下段の棚１５２から上段の棚１５２へと順次、板材製品Ｍが載置される。 The carrying-in / out robot arm on which the plate material M is placed switches the upper shelf 152 on the shelf 152 on which the plate material product M is placed from the retracted position to the use position, and then the next plate material is placed. Go to the plate processing machine for product M. In this manner, the plate material products M are sequentially placed from the lower shelf 152 of the plate stocker 150 to the upper shelf 152.
　板材ストッカ１５０からの板材製品Ｍの取り出しは、板材製品Ｍを取り出した棚１５２を作業員の手作業などにより、跳ね上げて、図２５の状態にする。そして、棚１５２を待避位置にし、その下の板材製品Ｍを取り出す。板材製品Ｍを取り出した棚１５２を作業員の手作業などにより、跳ね上げる。このようにして、棚板１５１の上段の棚板１５２から順次下段の棚板１５２に載置された板材製品Ｍを取り出す。 To remove the plate material product M from the plate material stocker 150, the shelf 152 from which the plate material product M has been taken out is flipped up by an operator's manual work or the like to the state shown in FIG. Then, the shelf 152 is set in the retracted position, and the plate material product M below it is taken out. The shelf 152 from which the plate product M has been taken out is flipped up manually by an operator. In this manner, the plate product M placed on the lower shelf 152 is sequentially taken out from the upper shelf 152 of the shelf 151.
　この板材ストッカ１５０を用いれば、各段の棚１５２ごとに板材製品Ｍが載置されるので、板材製品Ｍ同士が直接接触せず傷や潰れを生じさせることがない。また、板材製品Ｍが積み重ねにより崩れることがない。 If this plate material stocker 150 is used, the plate material products M are placed on the shelves 152 of each stage, so that the plate material products M are not in direct contact with each other and are not damaged or crushed. Moreover, the plate material product M does not collapse due to stacking.

　上記した板材ストッカ１５０を用いたシステムであれば、搬出入用ロボットアーム等で棚位置を切り替えるだけで、板材製品を積載できるので、構成が簡略化することができる。しかしながら、板材製品を積載するためには、棚板１５２を退避位置から使用位置に切り換えるという動作が必要になり、その分作業性が悪くなる。また、板材製品を載置するための棚板１５２を必要とし、その分材料費が嵩むという難点もあった。 In the system using the above-described plate stocker 150, the plate product can be loaded only by switching the shelf position with a loading / unloading robot arm or the like, so that the configuration can be simplified. However, in order to load a plate product, an operation of switching the shelf board 152 from the retracted position to the use position is required, and workability is deteriorated accordingly. Moreover, the shelf board 152 for mounting a board | plate material product is required, and there also existed a difficulty that material cost increased correspondingly.
　この発明は、上記した従来の問題点を解消するためになされたものにして、簡素化した構成で作業性の良好な板材収納装置を提供することを目的とする。 The present invention has been made to solve the above-described conventional problems, and an object of the present invention is to provide a plate material storage device having a simple structure and good workability.

A plurality of receiving plates are rotatably mounted at predetermined intervals, and the receiving plates are obliquely placed on a mounting portion for placing a plate material on a front portion and a rear portion with a mounting hole for attachment to the support member as a center. The receiving plate has a rear end portion extending upward, and the receiving plate rotates in a first direction in which the front end of the mounting portion faces upward by the weight of the receiving plate, and the receiving plate is positioned below and below the rear end portion. When the tip of the rear end of the plate is not in contact, the plate moves to an escape position where the plate can move up and down, and when the lower receiving plate holds the plate, the lower side and lower side of the rear end of the receiving plate Position The rear end of the receiving plate abuts against the dead weight of the receiving plate, rotates in a second direction opposite to the first direction, and moves to a calling position for guiding the plate material. did.
　また、前記支持部材に前記受けプレートの先端部と当接する第１ストッパが設けられ、前記受けプレートの先端が当接すると受けプレートが、前記逃がしの位置にセットされるように構成することができる。 Further, the support member may be provided with a first stopper that abuts against the tip of the receiving plate, and the receiving plate is set at the escape position when the tip of the receiving plate abuts. .
　また、前記呼び込みの位置の受けプレートの載置部に板材が載置されると、板材の自重により、受けプレートが第２の方向に回転し、板材保持位置に到達するように構成した。 In addition, when the plate material is placed on the receiving portion of the receiving plate at the calling position, the receiving plate rotates in the second direction due to the weight of the plate material, and reaches the plate material holding position.
　また、前記支持部材に、板材保持位置に前記受けプレートが位置する際の載置部の下側の支持部と当接する第２ストッパを設ければよい。 Further, the support member may be provided with a second stopper that comes into contact with the lower support portion of the placement portion when the receiving plate is positioned at the plate material holding position.
　また、最下段の受けプレートは、板材が載置されていない状態では、板材を案内する呼び込みの位置に移動するように構成すればよい。 Further, the lowermost receiving plate may be configured to move to a calling position for guiding the plate material when the plate material is not placed.
　また、前記支持部材は、一方に少なくとも２つ所定の間隔を隔てて配置されるとともに、他方に対向するように少なくとも２つ所定の間隔を隔てて配置されるように構成することができる。 Further, at least two of the support members may be arranged at a predetermined interval on one side, and at least two of the support members may be arranged at a predetermined interval so as to face the other.
　また、前記受けプレートの載置部の先端は半円状に形成され、前記受けプレートの載置部の後端には、板材端部が当接する段部を形成するように構成できる。 Further, the front end of the receiving portion of the receiving plate is formed in a semicircular shape, and a step portion with which the end of the plate material abuts can be formed at the rear end of the receiving portion of the receiving plate.
　この発明の板材収納装置によれば、板材加工機によって加工されたドアパネルやエンジンフードなどの板材を上から下へ移動させることで、板材収納装置に収納状態と取り出し状態を特別に変更させることなく、受けプレートと板材の自重により、下段から順次上段に板材を収納保管できる。そして、板材収納装置に収納された板材を上段から順次上へ移動させることで、板材収納装置に収納状態と取り出し状態を特別に変更させることなく受けプレートと板材の自重により、板材を取り出し可能状態にして加工機への搬送、板材の梱包などの作業を効率よく行うことができる。 According to the plate material storage device of the present invention, the plate material storage device is moved from top to bottom without moving the plate material storage device from the storage state and the take-out state specially by moving the plate material such as the door panel and engine hood processed by the plate material processing machine. By the weight of the receiving plate and the plate material, the plate material can be stored and stored sequentially from the lower stage to the upper stage. And, by moving the plate material stored in the plate material storage device sequentially from the upper stage, the plate material can be taken out by the weight of the receiving plate and the plate material without causing the plate material storage device to change the storage state and the pickup state specially.
