Description

竪型射出成形機の加熱筒交換方法及び加熱筒交換治具Heating tube replacement method and heating tube replacement jig for vertical injection molding machine
　本発明は、竪型射出成形機の加熱筒交換方法及び加熱筒交換治具に係り、特に、射出ユニットに備えられた加熱筒保持プレートに対する加熱筒の着脱作業を容易かつ安全に行う手段に関する。 The present invention relates to a heating cylinder replacement method and a heating cylinder replacement jig of a vertical injection molding machine, and more particularly to means for easily and safely attaching and detaching a heating cylinder to and from a heating cylinder holding plate provided in an injection unit.
　竪型射出成形機は、射出ユニットに備えられた加熱筒保持プレートに対して加熱筒が吊り下げられた形で取り付けられているため、加熱筒保持プレートから加熱筒を取り外すためには、加熱筒を支えながら加熱筒保持プレートに加熱筒を固定しているボルトを取り外し、ボルトを取り外した後は、加熱筒を所要の作業位置又は保管位置まで移送する必要がある。しかしながら、加熱筒は重量が大きいので、これを人力で支えながらボルトの取り外し作業を行うことは、作業者の肉体的負担が大きく、作業者に酷である。また、加熱筒を支えきれずに落としたり、他の機器に衝突させる恐れがあるので、安全上も問題である。勿論、加熱筒保持プレートに対して加熱筒を取り付ける場合にも、これと同様の問題が生じる。 The vertical injection molding machine is attached in such a manner that the heating cylinder is suspended from the heating cylinder holding plate provided in the injection unit. Therefore, in order to remove the heating cylinder from the heating cylinder holding plate, the heating cylinder It is necessary to remove the bolt that fixes the heating cylinder to the heating cylinder holding plate while supporting and to remove the bolt, and to transfer the heating cylinder to a required working position or storage position. However, since the heating cylinder is heavy, performing the bolt removing operation while supporting the heating tube with human power increases the physical burden on the operator and is severe to the operator. In addition, the heating cylinder may be dropped without being supported or may collide with other equipment, which is also a safety issue. Of course, the same problem occurs when the heating cylinder is attached to the heating cylinder holding plate.
　従来、上述の問題を解決するため、スクリュ駆動装置を上下動可能に取り付けるための加熱筒保持プレートである取付板の下方に、スクリュ駆動装置と一体的に上下動する保持装置を着脱可能に備え、この保持装置にスクリュ駆動装置から分離された可塑化ユニットを垂下した状態で保持して、縦型射出成形機の機械中心位置から離隔した位置までスライドさせる技術が提案されている（例えば、特許文献１参照。）。この特許文献１に記載の技術によれば、スクリュ駆動装置に対する可塑化ユニットの脱着作業に際して、可塑化ユニットを保持装置にて保持して所定の位置まで移送するので、大重量の可塑化ユニットを人力で支える必要がなく、作業を効率的かつ安全に行うことができる。 Conventionally, in order to solve the above-mentioned problem, a holding device that moves up and down integrally with the screw driving device is detachably provided below a mounting plate that is a heating cylinder holding plate for mounting the screw driving device so as to be movable up and down. A technology has been proposed in which the plasticizing unit separated from the screw driving device is held by the holding device in a suspended state and slid to a position separated from the machine center position of the vertical injection molding machine (for example, a patent Reference 1). According to the technique described in Patent Document 1, when the plasticizing unit is attached to or detached from the screw driving device, the plasticizing unit is held by the holding device and transferred to a predetermined position. There is no need to support it manually, and work can be done efficiently and safely.

　しかしながら、特許文献１に記載の技術は、保持装置として相対向に配置された２つのＬ字形のレールを用い、該レールの水平辺に可塑化ユニットに形成された係合段部を係合するというものであるので、所定の位置に所定の係合段部が形成された特定の可塑化ユニットにしか対応できず、係合段部を有しない可塑化ユニットの着脱に汎用的に応用できないという問題がある。 However, the technique described in Patent Document 1 uses two L-shaped rails arranged opposite to each other as a holding device, and engages an engaging step formed on the plasticizing unit on the horizontal side of the rail. Therefore, it can be applied only to a specific plasticizing unit in which a predetermined engagement step portion is formed at a predetermined position, and cannot be universally applied to attachment / detachment of a plasticizing unit having no engagement step portion. There's a problem.
　また、可塑化ユニットの取り付け及び取り外しに際しては、スクリュ駆動装置及び保持装置を適宜上下動して、スクリュ駆動装置と可塑化ユニットの距離を調整する必要があるが、特許文献１には、これらスクリュ駆動装置及び保持装置の上下動を自動的に行う手段が開示されておらず、作業者が目視にて各装置間の距離を確認しながら手動にてスクリュ駆動装置及び保持装置を上下動しなくてはならないので、作業能率が十分に高いとは言い難い。 Further, when attaching and detaching the plasticizing unit, it is necessary to adjust the distance between the screw driving device and the plasticizing unit by appropriately moving the screw driving device and the holding device up and down. Means for automatically moving the drive device and the holding device up and down is not disclosed, and the operator does not manually move the screw drive device and the holding device while visually checking the distance between the devices. It is hard to say that work efficiency is high enough.
　加えて、上述のように可塑化ユニットの取り付け及び取り外しに際しては、スクリュ駆動装置及び保持装置を適宜のタイミングで上下動するなどの複雑な作業手順を実施する必要があるが、特許文献１には、作業手順を作業者に教示する手段が何ら開示されていないので、特別な知識や熟練を備えた者でなければ可塑化ユニットの交換作業を行うことが難しく、この点にも改善の余地がある。 In addition, when attaching and removing the plasticizing unit as described above, it is necessary to carry out complicated work procedures such as moving the screw drive device and the holding device up and down at an appropriate timing. Since no means for teaching the work procedure to the worker is disclosed, it is difficult for a person with special knowledge and skill to perform the plasticizing unit replacement work, and there is room for improvement in this respect as well. is there.
　本発明は、上述の点に鑑みてなされたものであり、その目的とするところは、既設の竪型射出成形機に汎用的に適用でき、かつ非熟練者であっても可塑化ユニットの着脱作業を容易かつ高能率に実施可能な加熱筒交換方法及び加熱筒交換治具を提供することにある。 The present invention has been made in view of the above-described points, and the object of the present invention is to be applied universally to existing vertical injection molding machines and to attach and detach the plasticizing unit even for non-experts. An object of the present invention is to provide a heating cylinder replacement method and a heating cylinder replacement jig capable of easily and efficiently performing work.

In the method of replacing the heating cylinder of the vertical injection molding machine, when performing the attaching / detaching operation of the heating cylinder, the control device causes the display device to drive the nozzle touch motor and to perform the heating cylinder replacement treatment for the die plate. The heating for the heating cylinder holding plate, including a procedure for attaching and detaching a tool, a procedure for holding the heating cylinder to the heating cylinder replacement jig, and a procedure for transferring the heating cylinder held by the heating cylinder replacement jig The cylinder attachment / detachment procedure is displayed, and the operator performs the attachment / detachment operation of the heating cylinder with respect to the heating cylinder holding plate in accordance with the attachment / detachment operation procedure displayed on the display device.
　このように、加熱筒保持プレートに対する加熱筒の着脱手順を表示装置に表示し、作業者がこの表示装置に表示された着脱手順に従って加熱筒の着脱作業を行うようにすると、特別な知識や熟練がない作業者でも加熱筒の交換が可能になるので、加熱筒の交換作業を随時かつ円滑に行うことができる。また、この場合において、加熱筒交換治具を用いた加熱筒の着脱作業手順を表示装置に表示し、作業者が所要の加熱筒交換治具を用いて加熱筒の着脱作業を行うようにすると、作業者は大重量の加熱筒を加熱筒交換治具にて保持することができ、これを人力で支える必要がないので、加熱筒の着脱作業を容易かつ安全なものにすることができる。 As described above, when the heating cylinder attaching / detaching procedure with respect to the heating cylinder holding plate is displayed on the display device, and the worker performs the attaching / detaching operation of the heating cylinder according to the attaching / detaching procedure displayed on the display device, special knowledge and skill are obtained. Even an operator who does not have the need to replace the heating cylinder can perform the replacement operation of the heating cylinder at any time and smoothly. Further, in this case, when the heating tube attaching / detaching work procedure using the heating tube replacement jig is displayed on the display device, the operator performs the attaching / detaching operation of the heating tube using the required heating tube replacing jig. An operator can hold a heavy heating cylinder with a heating cylinder replacement jig and does not need to support this manually, so that the heating cylinder can be attached and detached easily and safely.

　かかる構成の加熱筒交換治具を用いると、加熱筒挿入保持部を加熱筒保持プレートに吊り下げられた加熱筒の直下まで移動することによって、加熱筒保持プレートから取り外された加熱筒の先端部を加熱筒挿入保持部内に挿入して保持することが可能となり、その状態から、スライダ本体に対して加熱筒挿入保持部が固定されたスライダ板をスライドさせることにより、加熱筒を竪型射出成形機の側方部分まで安全かつ容易に移動することができる。また、加熱筒保持プレートに対する加熱筒の取り付け時には、竪型射出成形機の側方部分において加熱筒交換治具の加熱筒挿入保持部内に加熱筒の先端部を挿入し、その状態から、スライダ本体に対して加熱筒挿入保持部が固定されたスライダ板をスライドさせることにより、加熱筒を加熱筒保持プレートの加熱筒取付位置の直下まで安全かつ容易に移動することができる。このように、本構成の加熱筒交換治具は、スライダ板に備えられた加熱筒挿入保持部内に加熱筒の先端部を挿入することによって加熱筒を保持するので、加熱筒に特別な加工を施す必要がなく、一般的な構成の加熱筒の交換作業に汎用的に適用することができる。 When the heating tube replacement jig having such a configuration is used, the tip of the heating tube removed from the heating tube holding plate is moved by moving the heating tube insertion holding portion to just below the heating tube suspended from the heating tube holding plate. Can be inserted and held in the heating cylinder insertion holding section, and from that state, the heating cylinder is formed into a vertical injection molding by sliding the slider plate with the heating cylinder insertion holding section fixed to the slider body. It can be moved safely and easily to the side of the machine. Also, when the heating cylinder is attached to the heating cylinder holding plate, the tip of the heating cylinder is inserted into the heating cylinder insertion holding portion of the heating cylinder replacement jig in the side portion of the vertical injection molding machine, and from this state, the slider body On the other hand, by sliding the slider plate to which the heating tube insertion holding portion is fixed, the heating tube can be safely and easily moved to just below the heating tube mounting position of the heating tube holding plate. In this way, the heating cylinder replacement jig of this configuration holds the heating cylinder by inserting the tip of the heating cylinder into the heating cylinder insertion holding section provided on the slider plate, so that the heating cylinder is specially processed. This is not necessary, and can be applied universally to replacement work of a heating cylinder having a general configuration.
　また本発明は、前記構成の竪型射出成形機の加熱筒交換方法において、前記加熱筒保持プレートに対する前記加熱筒の取り付け時には、竪型射出成形機の側方に引き出された前記加熱筒挿入保持部に前記加熱筒の先端部を挿入した後、前記スライダ板を前記スライダ本体に対して摺動させて、前記加熱筒挿入保持部に保持された前記加熱筒を前記加熱筒保持プレートの下方の所定位置まで移送し、前記加熱筒保持プレートからの前記加熱筒の取り外し時には、前記加熱筒保持プレートから取り外された前記加熱筒の先端部を前記加熱筒挿入保持部に挿入した後、前記スライダ板を前記スライダ本体に対して摺動させて、前記加熱筒挿入保持部に保持された前記加熱筒を竪型射出成形機の側方の所定位置まで移送することを特徴とする。 According to the present invention, in the heating cylinder replacement method for the vertical injection molding machine having the above-described configuration, when the heating cylinder is attached to the heating cylinder holding plate, the heating cylinder is inserted and held by the side of the vertical injection molding machine.

　かかる構成によると、スライダ板をスライダ本体に対して摺動させるだけで、加熱筒を１の所定位置から他の所定位置まで移送することができるので、加熱筒の交換作業を容易なものにすることができる。 According to such a configuration, the heating cylinder can be transferred from one predetermined position to another predetermined position simply by sliding the slider plate with respect to the slider body, so that the heating cylinder can be easily replaced. be able to.
　また本発明は、前記構成の竪型射出成形機の加熱筒交換方法において、前記制御装置は、作業者からの前記ノズルタッチ用モータの駆動指令を受けたとき、前記ノズルタッチ用モータの駆動を制御し、前記加熱筒の先端部を前記加熱筒交換治具と干渉しない適宜の位置まで上昇又は下降させ、当該適宜の位置で停止させることを特徴とする。 According to the present invention, in the heating cylinder replacement method of the vertical injection molding machine having the above-described configuration, when the control device receives a drive command for the nozzle touch motor from an operator, the control device drives the nozzle touch motor.

And a cylindrical heating tube insertion holding portion fixed to the upper surface of the slider plate.
　かかる構成によると、スライダ板に備えられた加熱筒挿入保持部内に加熱筒の先端部を挿入することによって加熱筒の保持及び移送を行うことができるので、加熱筒保持プレートに対する加熱筒の着脱作業を容易化できると共に、加熱筒に特別な加工を施す必要がないので、一般的な構成の加熱筒の交換作業に汎用的に適用することができる。 According to this configuration, the heating cylinder can be held and transferred by inserting the tip of the heating cylinder into the heating cylinder insertion holding section provided in the slider plate, so that the heating cylinder can be attached to and detached from the heating cylinder holding plate.

　まず、本発明が適用される竪型射出成形機の射出ユニット周りの構成を、図１を用いて説明する。 First, a configuration around an injection unit of a vertical injection molding machine to which the present invention is applied will be described with reference to FIG.
　この図から明らかなように、本例の竪型射出成形機においては、竪型に構成された射出ユニット１が、竪型に構成された型開閉ユニットの最上部に位置するダイプレート２の上面に、中空のベースブラケット３を介して取り付けられている。なお、ダイプレート２の下面側には、図示しない上金型が取り付けられる。 As is apparent from this figure, in the vertical injection molding machine of this example, the upper surface of the die plate 2 in which the injection unit 1 configured in a vertical pattern is positioned at the top of the mold opening / closing unit configured in a vertical pattern. Are attached via a hollow base bracket 3. An upper mold (not shown) is attached to the lower surface side of the die plate 2.
　射出ユニット１は、相対向に配置され、ダイプレート２に対して互いに所定の範囲で上下動する加熱筒保持プレート４及び直動プレート５と、加熱筒保持プレート４から吊り下げられた加熱筒ユニット６と、加熱筒ユニット６を上下動するノズルタッチ用ボールネジ機構７及びノズルタッチ用電動サーボモータ８と、加熱筒ユニット６内に回転可能かつ上下動可能に収納され、基端部が直動プレート５に回転可能に保持されたスクリュ９と、スクリュ９を回転駆動する計量用電動サーボモータ１０と、直動プレート５及びスクリュ９を一体として前後進させる射出用ボールネジ機構１１及び射出用電動サーボモータ１２とを備えている。加熱筒ユニット６は、加熱筒６ａと、その先端部に取り付けられたノズル６ｂと、加熱筒６ａの基端部に取り付けられたホッパブロック６ｃとからなり、ノズル６ｂは、ダイプレート２に開設された加熱筒挿入孔２ａを通して、図示しない上金型に開設された樹脂注入穴に押し付けられる。また、射出用ボールネジ機構１１は、加熱筒保持プレート４に回転可能に取り付けられたナット体１１ａと、該ナット体１１ａに螺合されたネジ軸１１ｂとからなる。なお、本実施形態においては、ノズルタッチ用のモータとして電動サーボモータ８を用いているが、これに代えて通常の電動モータを用いることもできる。本明細書においては、これらを総称して「ノズルタッチ用モータ」ということがある。 The injection unit 1 is arranged opposite to each other, and the heating cylinder holding plate 4 and the linear motion plate 5 that move up and down with respect to the die plate 2 within a predetermined range, and the heating cylinder unit suspended from the heating cylinder holding plate 4 6, a nozzle touch ball screw mechanism 7 that moves up and down the heating cylinder unit 6 and an electric servo motor 8 for nozzle touch, and is housed in the heating cylinder unit 6 so as to be rotatable and movable up and down, and the base end portion is a direct acting plate 5, a screw 9 rotatably held by the motor 5, a metering electric servomotor 10 that rotationally drives the screw 9, an injection ball screw mechanism 11 that moves the linear motion plate 5 and the screw 9 forward and backward, and an electric servomotor for injection 12. The heating cylinder unit 6 includes a heating cylinder 6a, a nozzle 6b attached to the distal end portion thereof, and a hopper block 6c attached to the proximal end portion of the heating cylinder 6a. The nozzle 6b is opened on the die plate 2. Through the heating cylinder insertion hole 2a, it is pressed against a resin injection hole provided in an upper mold (not shown). The injection ball screw mechanism 11 includes a nut body 11a that is rotatably attached to the heating cylinder holding plate 4, and a screw shaft 11b that is screwed into the nut body 11a. In the present embodiment, the electric servo motor 8 is used as a nozzle touch motor, but a normal electric motor may be used instead. In the present specification, these may be collectively referred to as “nozzle touch motor”.
　なお、射出ユニット１に備えられる各モータ８，１０，１２の駆動・停止は、竪型射出成形機に備えられた制御装置２１によって制御される。また、この制御装置２１には表示装置２２が付設されており、射出ユニット１の設定条件、駆動状況及び加熱筒保持プレート４に対する加熱筒ユニット６の着脱手順等が表示される。 The driving / stopping of the motors 8, 10, 12 provided in the injection unit 1 is controlled by a control device 21 provided in the vertical injection molding machine. In addition, a display device 22 is attached to the control device 21, and the setting conditions of the injection unit 1, the driving condition, the attaching / detaching procedure of the heating cylinder unit 6 with respect to the heating cylinder holding plate 4 and the like are displayed.
　加熱筒保持プレート４には、ノズルタッチ用のボールネジ機構７のナット体７ａが回転可能に保持されており、該ナット体７ａには、ボールネジ機構７のネジ軸７ｂが螺合されている。該ボールネジ機構７は、加熱筒ユニット６を中心として１２０°角度間隔で３つ設けられており、各ボールネジ機構７のネジ軸７ｂの下端部は、ベースブラケット３の上面側にそれぞれ固定され、各ネジ軸７ｂの上端側は、連結ブラケット１３に固定されている。本実施形態では、ボールネジ機構７のネジ軸７ｂには、ボールネジ機構用の螺旋溝とボールスプライン機構用の直線溝とがクロスするように形成されていて、ネジ軸７ｂは、ネジ軸の機能とボールスプライン軸としての機能を兼ね備えるようになっている。各ネジ軸７ｂは、加熱筒保持プレート４に固定されたスプライン外筒体１４及び後記する直動プレート５に固定されたスプライン外筒体１５に、それぞれボールスプライン結合されており、これにより、加熱筒保持プレート４及び直動プレート５は、ネジ軸７ｂの軸方向には移動可能で、回転は不能となる。 A nut body 7a of a ball screw mechanism 7 for nozzle touch is rotatably held on the heating cylinder holding plate 4, and a screw shaft 7b of the ball screw mechanism 7 is screwed to the nut body 7a. Three ball screw mechanisms 7 are provided at an angular interval of 120 ° with the heating cylinder unit 6 as the center. The lower ends of the screw shafts 7b of the ball screw mechanisms 7 are fixed to the upper surface side of the base bracket 3, respectively. The upper end side of the screw shaft 7 b is fixed to the connection bracket 13. In the present embodiment, the screw shaft 7b of the ball screw mechanism 7 is formed so that the spiral groove for the ball screw mechanism and the linear groove for the ball spline mechanism cross, and the screw shaft 7b has the function of the screw shaft. It also has a function as a ball spline shaft. Each screw shaft 7b is connected to a spline outer cylinder 14 fixed to the heating cylinder holding plate 4 and a spline outer cylinder 15 fixed to a linear motion plate 5 to be described later by ball spline coupling. The cylinder holding plate 4 and the linear motion plate 5 are movable in the axial direction of the screw shaft 7b and cannot be rotated.
　ノズルタッチ用サーボモータ８の回転は、ボールネジ機構７のナット体７ａと一体回転する被動プーリ７ｃに伝達され、ナット体７ａが回転することで、ナット体７ａと一体となって加熱筒保持プレート４が下降駆動若しくは上昇駆動される。これにより、ノズルが図示しない上金型の樹脂注入孔に当接する位置と後に説明する加熱筒交換治具と干渉しない所定の位置との間で往復駆動される。 The rotation of the nozzle touch servomotor 8 is transmitted to a driven pulley 7c that rotates integrally with the nut body 7a of the ball screw mechanism 7, and the nut body 7a rotates, so that the heating cylinder holding plate 4 is integrated with the nut body 7a. Is driven down or up. Thus, the nozzle is reciprocated between a position where the nozzle abuts a resin injection hole of the upper mold (not shown) and a predetermined position where the nozzle does not interfere with a heating cylinder replacement jig described later.
　直動プレート５には、計量用電動サーボモータ１０が搭載されており、該計量用電動サーボモータ１０の回転は、スクリュ９と一体回転する回転部材に固定された被動プーリ１６に伝達されていて、これによりスクリュ９が回転駆動されるようになっている。 The linear motion plate 5 is equipped with a metering electric servo motor 10, and the rotation of the metering electric servo motor 10 is transmitted to a driven pulley 16 fixed to a rotating member that rotates integrally with the screw 9. Thereby, the screw 9 is rotationally driven.
