Description
本発明は、搬出装置の排出口を閉塞する閉塞位置と搬出装置の排出口を開放する開放位置との間を旋回自在に搬出装置に装着された蓋部材を閉塞位置に強制すると共に蓋部材の自重により蓋部材が開放位置に旋回することを許容する蓋部材開閉装置に関する。 The present invention forces the lid member mounted on the carry-out device to the closed position so as to be pivotable between a closed position where the discharge port of the carry-out device is closed and an open position where the discharge port of the carry-out device is opened. The present invention relates to a lid member opening / closing device that allows a lid member to turn to an open position by its own weight.
一般に、マシニングセンタや旋盤等の工作機械で発生する切粉は、チップコンベア等の搬出装置により工作機械から搬出され、搬出された切粉は搬出装置の排出口の下方に設置された可動回収容器に一旦回収される。そして、切粉を収容した可動回収容器は作業者により処理設備に運搬される。 In general, chips generated on a machine tool such as a machining center or a lathe are carried out of the machine tool by an unloading device such as a chip conveyor, and the unloaded chips are transferred to a movable recovery container installed below the discharge port of the unloading device. Once recovered. And the movable collection | recovery container which accommodated the chip is conveyed by a worker to processing equipment.
長時間にわたる工作機械の自動運転が行われる際は、可動回収容器の容量を超える大量の切粉が発生する場合がある。従来、このような場合に作業者は、（１）工作機械の自動運転を一時停止させた上で、切粉を収容した可動回収容器を処理設備に運搬するか、あるいは、（２）工作機械の自動運転を停止させずに、切粉を収容した可動回収容器を空の可動回収容器に入れ替えた上で、切粉を収容した可動回収容器を処理設備に運搬していた。しかし、上記（１）の場合には、工作機械の自動運転を一時停止させるため生産性が低下し、かつ作業者が工作機械の自動運転の再稼働を忘れてしまうおそれがある。一方、上記（２）の場合には、複数の可動回収容器を配備する必要があり、かつ可動回収容器を入れ替える際に切粉が散乱してしまう問題がある。 When automatic operation of a machine tool for a long time is performed, a large amount of chips exceeding the capacity of the movable collection container may be generated. Conventionally, in such a case, the operator either (1) temporarily stops the automatic operation of the machine tool and then transports the movable collection container containing the chips to the processing facility, or (2) the machine tool. Without stopping the automatic operation, the movable collection container containing the chips was replaced with an empty movable collection container, and the movable collection container containing the chips was transported to the processing facility. However, in the case of the above (1), since the automatic operation of the machine tool is temporarily stopped, the productivity is lowered, and the operator may forget to restart the automatic operation of the machine tool. On the other hand, in the case of (2), it is necessary to provide a plurality of movable collection containers, and there is a problem that chips are scattered when the movable collection containers are replaced.
この点、下記特許文献１には、長時間にわたる工作機械の自動運転が行われる場合でも、可動回収容器の入れ替えの際の切粉の散乱が防止され、したがって自動運転を停止させることなく切粉を処理することができる集塵機が開示されている。この集塵機は、工作機械で発生する切粉を取り込むための吸入口と、吸入口から取り込まれた切粉を吸引するためのブロアと、吸入口から取り込まれた切粉を下部に落とすように構成された漏斗状のホッパーと、ホッパーからの切粉を集めるための落し口と、落し口を開閉するための落し口扉とを有する。そして、この集塵機では、落し口の下方に設置された可動回収容器で落し口から落下する切粉を回収する場合には落し口扉を開け、可動回収容器内の切粉が所定量を超えると落し口扉が閉じるので、可動回収容器の入れ替えの際の切粉の散乱が防止され、したがって自動運転を停止させることなく切粉を処理することができる。 In this regard, in Patent Document 1 below, even when automatic operation of a machine tool is performed for a long time, scattering of chips during replacement of the movable recovery container is prevented, and thus chips without stopping automatic operation. A dust collector that can handle the above is disclosed. This dust collector is configured to suck the chips generated by the machine tool, the blower for sucking the chips taken from the suction port, and the chips taken from the suction port to the lower part And a funnel-shaped hopper, a spout for collecting chips from the hopper, and a spout door for opening and closing the spout. And in this dust collector, when collecting the chips falling from the dropper with a movable collection container installed below the dropper, the dropper door is opened, and the chips in the movable collection container exceed a predetermined amount. Since the spout door is closed, scattering of the chips when the movable collection container is replaced is prevented, and therefore the chips can be processed without stopping the automatic operation.
上記特許文献１に開示された集塵機では制御盤の起動スイッチが操作されると開閉機構が落し口扉を開閉する構成となっており、開閉機構は流体圧駆動又は電動のアクチュエータから構成される。したがって、上記特許文献１に開示された集塵機では、制御盤やアクチュエータ等の設備導入のためのイニシャルコストに加えて、流体圧又は電力によってアクチュエータを作動させるためのランニングコストもかかるという問題がある。 In the dust collector disclosed in Patent Document 1, when the start switch of the control panel is operated, the opening / closing mechanism drops to open / close the mouth door, and the opening / closing mechanism is configured by a fluid pressure drive or an electric actuator. Therefore, the dust collector disclosed in Patent Document 1 has a problem in that in addition to the initial cost for introducing equipment such as a control panel and an actuator, there is also a running cost for operating the actuator by fluid pressure or electric power.
上記事実に鑑みてなされた本発明の課題は、流体圧又は電力等の動力ではなく、作業者による可動回収容器の運搬動作や重力を利用して蓋部材を開閉させることができる蓋部材開閉装置を提供することである。 An object of the present invention made in view of the above-described fact is that a lid member opening and closing device capable of opening and closing a lid member by using a transporting operation and gravity of a movable recovery container by an operator, instead of power such as fluid pressure or electric power.

It is. The movable collection container guide means 114 may be composed of a first guide member 116 and a second guide member 118 each extending substantially parallel to the rod guide means 112. In the illustrated embodiment, as shown in FIG. 6, the first guide member 116 is made of angle steel extending from the substrate 94 of the weight guide means 90 in the X direction at a distance from the rod guide means 112 in the Y direction. The second guide member 118 is made of angle steel that extends in the X direction at a distance from the first guide member 116 on the opposite side of the rod guide means 112 in the Y direction. The distance in the Y direction between the first guide member 116 and the second guide member 118 corresponds to the width of the movable collection container 142 described later. The first guide member 116 is connected to the rod guide means 112 via a connecting piece 120, and the connecting piece 120 is fixed to the floor by anchor bolts 122. At one end of the second guide member 118 that is shorter than the first guide member 116 (the end on the front side in FIG. 6), an inclined piece 124 that is inclined in a direction away from the first guide member 116 is disposed. Attached, and a fixed piece 128 fixed to the floor by anchor bolts 126 is attached. The inclined piece 124 can be made of angle steel. Further, the other end portion of the second guide member 118 (the end portion on the back side in FIG. 6) is connected to the substrate 94 of the weight guide means 90 via a gate-shaped member 130 that can be formed from a metal square pipe material. ing. The gate-shaped member 130 includes a first column 132 extending upward from the upper surface of the substrate 94 of the weight guide means 90, a second column 134 extending upward from the other end of the second guide member 118, and an upper end of the first column 132. And a beam 136 that extends across the upper end of the second support post 134 and extends in the Y direction. A fixing piece 140 fixed to the floor by an anchor bolt 138 is attached to the lower end portion of the second support column 134. The Y direction is a direction indicated by an arrow Y in FIG. 6 and is orthogonal to the X direction. The plane defined by the X direction and the Y direction is substantially horizontal.
図１に示すとおり、ウエイト案内手段９０の一対の案内部材９６の間にはウエイト部材８が配置されている。そして、ウエイト部材８の被案内ローラー３４が通るローラー通路を案内部材９６の内面が規定することによって、ウエイト部材８の昇降経路をウエイト案内手段９０が規定している。これによって、ウエイト部材８はワイヤー６に張力を作用させる下降位置とワイヤー６の張力を解除する上昇位置との間を昇降自在となっている。図示の実施形態では、ウエイト部材８が下降位置に位置する時に下降制限部材１０２の上端部がウエイト本体２６の下面に接触し、下降位置を越えてウエイト部材８が下降するのが下降制限部材１０２によって制限されている。また、図示の実施形態では、ウエイト部材８が上昇位置から下降位置に移動した際には下降制限部材１０２の上端部にウエイト本体２６の下面が接触してウエイト部材８の下降が停止されるため、ウエイト部材８が上昇位置から下降位置に移動する際にワイヤー６に過剰な張力が発生するのが抑制され、したがってウエイト部材８の昇降の繰り返しによるワイヤー６の損傷が防止される。 As shown in FIG. 1, the weight member 8 is disposed between the pair of guide members 96 of the weight guide means 90. The weight guide means 90 defines the lifting path of the weight member 8 by the inner surface of the guide member 96 defining a roller passage through which the guided roller 34 of the weight member 8 passes. As a result, the weight member 8 can move up and down between a lowered position where the tension is applied to the wire 6 and a raised position where the tension of the wire 6 is released. In the illustrated embodiment, when the weight member 8 is located at the lowered position, the upper end portion of the lowering restriction member 102 contacts the lower surface of the weight body 26, and the lowering of the weight member 8 beyond the lowering position is caused by the lowering restriction member 102. Limited by. In the illustrated embodiment, when the weight member 8 moves from the raised position to the lowered position, the lower surface of the weight main body 26 comes into contact with the upper end portion of the lowering restricting member 102 and the lowering of the weight member 8 is stopped. When the weight member 8 moves from the raised position to the lowered position, excessive tension is prevented from being generated in the wire 6, and therefore damage to the wire 6 due to repeated lifting and lowering of the weight member 8 is prevented.
図１を参照して説明を続けると、ウエイト部材８のブラケット３６に旋回自在に連結されたロッド部材１０は、一対の走行手段６２によって下端部が後退位置と前進位置との間を進退自在となっている。ロッド部材１０は、ロッド部材１０の下端部が図１に示す後退位置に位置する時には、下方に向かって排出管１２の排出口１２ａから離隔する方向に傾斜して延在する。すなわち、ロッド部材１０は実質上水平な床面に対して傾斜して延在する。ロッド部材１０の下端部が後退位置から前進位置に向かって前進されると、ロッド部材１０と床面とで規定される傾斜角度が次第に増大する。また、ロッド部材１０の下端部に連結された一対の走行手段６２はロッド案内手段１１２を跨って配置されているので、ロッド部材１０の下端部が進退する時には走行手段６２がＸ方向に沿ってロッド案内手段１１２によって案内され、したがってロッド部材１０の下端部の進退経路がロッド案内手段１１２によってＸ方向に規定されている。 1, the rod member 10 that is pivotably connected to the bracket 36 of the weight member 8 has a lower end portion that can be moved back and forth between a retracted position and an advanced position by a pair of traveling means 62. It has become. When the lower end portion of the rod member 10 is located at the retracted position shown in FIG. 1, the rod member 10 extends downward and inclines in a direction away from the discharge port 12 a of the discharge pipe 12. That is, the rod member 10 extends with an inclination with respect to a substantially horizontal floor surface. When the lower end portion of the rod member 10 is advanced from the retracted position toward the advanced position, the inclination angle defined by the rod member 10 and the floor surface gradually increases. Further, since the pair of travel means 62 connected to the lower end portion of the rod member 10 is disposed across the rod guide means 112, the travel means 62 moves along the X direction when the lower end portion of the rod member 10 advances and retreats. Guided by the rod guiding means 112, the forward / backward path of the lower end portion of the rod member 10 is defined in the X direction by the rod guiding means 112.
図７には、排出管１２の排出口１２ａから排出される切粉（排出物）を回収する可動回収容器１４２が示されている。可動回収容器１４２は、上端部が開放された箱形状の容器本体１４４と、容器本体１４４が搭載された台車１４６と、台車１４６の搭載部１４８の幅方向片端部から幅方向外方に突出する押圧板１５０とを備える。容器本体１４４に切粉を収容する可動回収容器１４２は、作業者によって台車１４６のハンドル部１５２が把持されて運搬される。 FIG. 7 shows a movable recovery container 142 that recovers chips (discharged matter) discharged from the discharge port 12 a of the discharge pipe 12. The movable collection container 142 protrudes outward in the width direction from one end in the width direction of the box-shaped container main body 144 having an open upper end, the carriage 146 on which the container main body 144 is mounted, and the mounting portion 148 of the carriage 146. And a pressing plate 150. The movable collection container 142 that stores the chips in the container main body 144 is transported while the handle portion 152 of the carriage 146 is gripped by the operator.
図１を参照して、排出管１２の排出口１２ａを閉塞する閉塞位置に蓋部材４が強制されている状態について説明する。排出口１２ａの下方から可動回収容器１４２が離隔している場合には、ウエイト部材８の自重、又はウエイト部材８及びロッド部１０材の双方の自重によって、ウエイト部材８は下降位置に位置すると共に、ロッド部材１０の下端部は後退位置に位置する。このため、ウエイト部材８がワイヤー６の他端部を引っ張りワイヤー６に張力を作用させることによって、図１に示すとおり、蓋部材４が閉塞位置に強制される。したがって、排出口１２ａの下方に位置づけられた可動回収容器１４２に収容された切粉が所定量を超えた場合などであって、排出口１２ａの下方から処理設備へと可動回収容器１４２が作業者によって運搬される際は、蓋部材開閉装置２によって蓋部材４が閉塞位置に強制されるので、排出口１２ａの下方から可動回収容器１４２が離隔していても切粉が散乱することはない。 With reference to FIG. 1, a state in which the lid member 4 is forced to the closing position for closing the discharge port 12a of the discharge pipe 12 will be described. When the movable recovery container 142 is separated from the lower side of the discharge port 12a, the weight member 8 is positioned at the lowered position by the weight of the weight member 8 or by the weight of both the weight member 8 and the rod portion 10 material. The lower end portion of the rod member 10 is located at the retracted position. For this reason, the weight member 8 pulls the other end portion of the wire 6 to apply tension to the wire 6, thereby forcing the lid member 4 to the closed position as shown in FIG. 1. Therefore, when the amount of chips stored in the movable recovery container 142 positioned below the discharge port 12a exceeds a predetermined amount, the movable recovery container 142 is moved from the lower side of the discharge port 12a to the processing facility. Since the lid member 4 is forced to the closed position by the lid member opening / closing device 2, chips are not scattered even if the movable recovery container 142 is separated from the lower side of the discharge port 12 a.
一方、排出口１２ａの下方に可動回収容器１４２が進入する際には、可動回収容器１４２の台車１４６が可動回収容器案内手段１１４によってＸ方向に案内されるため、可動回収容器１４２の進入経路が可動回収容器案内手段１１４によって、ロッド部材１０の進退経路に実質上平行なＸ方向に規定される。また、図示の実施形態では、可動回収容器案内手段１１４の第２案内部材１１８の片端部に傾斜片１２４が付設されているため、可動回収容器案内手段１１４によって規定された可動回収容器１４２の進入経路から若干ずれた状態で可動回収容器１４２が排出口１２ａの下方へと進入した場合でも、規定された可動回収容器１４２の進入経路に可動回収容器１４２が傾斜片１２４によって案内される。そして、排出口１２ａの下方に可動回収容器１４２が進入すると、図８に示すとおり、可動回収容器１４２の押圧板１５０がロッド部材１０の被押圧部材４８を押圧してロッド部材１０の下端部を後退位置から前進位置に向けて前進させる。そうすると、ワイヤー６に張力を作用させる下降位置からワイヤー６の張力を解除する上昇位置に向かってウエイト部材８が上昇されてワイヤー６の張力が解除される。これによって図９に示すとおり、蓋部材４の自重により蓋部材４が閉塞位置から開放位置に旋回する。さらに、図示の実施形態では、可動回収容器１４２の進入経路の奥側に門型部材１３０が配置されているから、排出口１２ａの下方を可動回収容器１４２が通過することがなく、これによって、ロッド部材１０の下端部が前進位置を越えて前進することがないと共に、ウエイト部材８が上昇位置を越えて上昇することがないようになっている。 On the other hand, when the movable collection container 142 enters the lower side of the discharge port 12a, the carriage 146 of the movable collection container 142 is guided in the X direction by the movable collection container guiding means 114. The movable collection container guiding means 114 defines the X direction substantially parallel to the advance / retreat path of the rod member 10. In the illustrated embodiment, since the inclined piece 124 is attached to one end portion of the second guide member 118 of the movable collection container guide unit 114, the movable collection container 142 defined by the movable collection container guide unit 114 enters. Even when the movable recovery container 142 enters the lower side of the discharge port 12a in a state slightly deviated from the path, the movable recovery container 142 is guided by the inclined piece 124 to the defined entrance path of the movable recovery container 142. When the movable recovery container 142 enters below the discharge port 12a, the pressing plate 150 of the movable recovery container 142 presses the pressed member 48 of the rod member 10 as shown in FIG. Advance from the reverse position to the forward position. Then, the weight member 8 is raised from the lowered position where the tension is applied to the wire 6 to the raised position where the tension of the wire 6 is released, and the tension of the wire 6 is released. As a result, as shown in FIG. 9, the lid member 4 turns from the closed position to the open position by the weight of the lid member 4. Furthermore, in the illustrated embodiment, since the gate-shaped member 130 is disposed on the back side of the entry path of the movable recovery container 142, the movable recovery container 142 does not pass below the discharge port 12a. The lower end portion of the rod member 10 does not advance beyond the advance position, and the weight member 8 does not rise beyond the lift position.
以上のとおり、蓋部材開閉装置２においては、流体圧又は電力等の動力ではなく、作業者による可動回収容器１４２の運搬動作や重力（ウエイト部材８やロッド部材１０、蓋部材４等の自重）を利用して蓋部材４を開閉させることができ、したがって制御盤やアクチュエータ等のコストが抑制される。また、蓋部材開閉装置２においては、排出口１２ａの下方から可動回収容器１４２が離隔されることにより蓋部材４を閉塞位置に強制し、排出口１２ａの下方に可動回収容器１４２が進入することにより蓋部材４が開放位置に旋回することを許容するから、作業者は、可動回収容器１４２を運搬する際に工作機械の自動運転の停止及び再稼働のためのスイッチ操作や蓋部材４開閉のためのスイッチ操作をする必要がなく、したがってスイッチ操作ミスの発生が防止される。 As described above, in the lid member opening / closing device 2, not the power such as fluid pressure or electric power, but the operation of carrying the movable recovery container 142 by the operator and gravity (the weight of the weight member 8, the rod member 10, the lid member 4, etc.) Thus, the lid member 4 can be opened and closed, so that the cost of the control panel, actuator, etc. can be suppressed. Further, in the lid member opening / closing device 2, the movable recovery container 142 is separated from the lower side of the discharge port 12a to force the lid member 4 to the closed position, and the movable recovery container 142 enters under the discharge port 12a. Therefore, when the movable collection container 142 is transported, the operator can operate the switch for automatic operation stop and restart of the machine tool, and open / close the lid member 4. Therefore, it is not necessary to perform a switch operation for this purpose, and therefore occurrence of a switch operation error is prevented.
