【発明の詳細な説明】 受取りコンベヤに接着剤薄層を含。[Detailed description of the invention] Contains a thin layer of adhesive on the receiving conveyor.
浸した鉱滓綿の非硬化−次薄板を 送給する方法ならびにその装置 本発明は受取りコンベヤに接着剤薄層を含浸した鉱滓綿の非硬化−次薄板を送給 する工程に関し、請求の範囲第1項及び第9項の前文に記載の工程を実施する装 置にも関する。Uncured thin sheets of soaked slag cotton Delivery method and device The present invention feeds a receiving conveyor with uncured sheets of slag cotton impregnated with a thin layer of adhesive. With respect to the step of performing It also concerns the location.
鉱滓綿シートを製作する場合、高度の絶縁性能を生ずるので、なるべく均一にし がも均質に製品を仕上げることはむずかしい、なおその上、低密度においてなる べく弾性をもたせるべきであり、繊維が主にシート面に延ばされる必要がある0 弾性により、このシートは、充填及び移送の段階のために圧縮される。When manufacturing a mineral wool sheet, it should be made as uniform as possible because it produces a high degree of insulation performance. However, it is difficult to finish the product uniformly, and on top of that, the density is low. The material should be as elastic as possible, and the fibers should be stretched primarily on the sheet surface. Due to its elasticity, this sheet is compressed for the filling and transport stages.
この事を達成するために、その坪量が110ないし450 g / m 2の範 囲内で変動する薄い一次薄板は、好ましくはlOOないし200 g / m 2が、繊維解体後直ちに集合コンベヤに集められる。−次薄板が薄いほど仕上り 製品の品質は良い、薄い一次薄板を生産する場合に爺力を所望の水準に保持する には、−次薄板の速さは搬送装置の速さと同様に早くなければならない、普通で は、−次薄板の速さは100 m 7分以上であるが、−次薄板の坪量は、単に 100ないし200 g / m 2の範囲にあり、所望の水準に能力を保持す るためには一定な高速が要求される。In order to achieve this, the basis weight is in the range 110 to 450 g/m2 The thin primary lamina varying within the range preferably has a thickness of lOO to 200 g/m. 2 are collected on a collection conveyor immediately after fiber disassembly. −Next, the thinner the thin plate, the better the finish. The product quality is good, keeping the force at the desired level when producing thin primary sheets. In order to The speed of the −th sheet is more than 100 m 7 minutes, but the basis weight of the −th sheet is simply in the range of 100 to 200 g/m2 and maintain the capacity at the desired level. A constant high speed is required to achieve this.
鉱滓綿を折りたたむ各種の方法について、1948年からのアメリカ特許NO, 2,450,916に開示されており、またその他の特許の中でこれより新らし いイギリス特許NO,772,828に開示されている。これらの特許は振り子 式コンベヤにより一次薄板を折りたたむ方法について次に完成をしている。US Patent No. 1 from 1948 on various methods of folding slag cotton, No. 2,450,916, and more recent patents among other patents. It is disclosed in British Patent No. 772,828. These patents are a pendulum Next, we completed a method for folding primary thin plates using a type conveyor.
振り子式コンベヤが一次薄板の送出に用いられると、送出端部の速さは一次薄板 の速さと同一でありかくして送出の瞬間における薄板の折りたたみ、もしくは引 き伸ばしを回避するようになっている。ということが重要である。When a pendulum type conveyor is used to deliver the primary sheet, the speed at the sending end is faster than the primary sheet. is the same as the speed and thus the folding or pulling of the sheet at the moment of delivery. It is designed to avoid stretching. That is important.
現在のところ、この振り子機構は一般にその操作は、その遠位点が受取りコンベ ヤの上方で最も高い位置であり、振り子の下死点は受取りコンベヤに最も接近し ている。薄い一次薄板に所望の能力を与えるには、振り子式コンベヤの送出速さ を増すべきであり、しかしこのことは公知の装置では不可能である。実際に、軽 量の薄板を送出しまた振り子の高い周期をもった高速振り子式コンベヤは一次薄 板の配置に不正確さが生じている。連結棒により公知の方法で駆動されまた円弧 に沿って振動される振り子式コンベヤは、速さをそのコンベヤの送出端に加え、 このコンベヤは振り子がその中央位置にあるときには最高点にあり、遠位点にお いてはシヌソイド関数的に低減し零になり、この遠位点からはシヌンイド関数的 加速が再び生ずる。振り子式コンベヤの送出端は、その最低点において、−次薄 板を引き伸ばされることなく受取りコンベヤ上に均一な層に載置するには、送出 された綿薄板上方に、送出部の約0.2倍、これは一般に2mであるが、これだ け配置されねばならない、振り子と受取りコンベヤとの間の距離は、40cmも しくはそれ以上の長さであり、送出薄板の端部は平らでない、送出速さは約13 0m/分であり、形成される二次薄板の不揃い程度は送出部の約±5%である。Currently, this pendulum mechanism generally operates only when its distal point is connected to the receiving conveyor. the highest point above the conveyor, and the bottom dead center of the pendulum is closest to the receiving conveyor. ing. To provide the desired capacity for thin primary sheets, the delivery speed of the pendulum conveyor must be should be increased, but this is not possible with the known device. In fact, light A high-speed pendulum type conveyor with a high period of pendulum conveys a large amount of thin plate and There are inaccuracies in the placement of the plates. Driven in a known manner by connecting rods and arc A pendulum conveyor that is oscillated along adds velocity to the delivery end of the conveyor, This conveyor is at its highest point when the pendulum is in its central position, and at its distal point. , it decreases to zero in a sinusoidal manner, and from this distal point it decreases in a sinusoidal manner. Acceleration occurs again. At its lowest point, the delivery end of a pendulum conveyor is -thin To place the boards in an even layer on the receiving conveyor without being stretched, The length of the thin cotton board is approximately 0.2 times the length of the sending section, which is generally 2 m, but this is the case. The distance between the pendulum and the receiving conveyor, which must be placed or longer, the edges of the delivery lamina are uneven, and the delivery speed is approximately 13 0 m/min, and the degree of irregularity of the formed secondary thin plate is about ±5% of the sending part.
この事実は、二次薄板は所望幅をもつ無欠陥薄板を達成するために従属的に大き い幅を与えられねばならない、その理由は望まない材料がすでに切断し終ってい るからである。これは著しい材料の損失を意味する。This fact indicates that the secondary sheet must be made dependently larger in order to achieve a defect-free sheet with the desired width. A wide width must be provided because the undesired material has already been cut. This is because that. This represents a significant loss of material.
振り子送出機構は、公知であって、この機構では、折りたたみ工程が実施され、 それは連続的に一定高さを支持体上に保持しながら一次薄板を送出する。受取り コンベヤ上に一定高さを保って振り子式コンベヤの送出端を維持する1つの関節 システムが設けられ、しかも鎖/連結棒機構により、遊#/接近運動が得られる 。この振動運動の速さの状態を見ると、中央部分で一定速さであり、両端におい てシノイダル減速と加速相とが生ずる。Pendulum delivery mechanisms are known in which a folding process is carried out, It continuously delivers the primary sheet while maintaining a constant height on the support. Receipt One joint that maintains the delivery end of a pendulum conveyor at a constant height above the conveyor. system is provided, and the chain/connecting rod mechanism provides free movement/approach movement. . Looking at the speed of this vibration movement, it is constant in the center and at both ends. Therefore, a synoidal deceleration and acceleration phase occur.
振り子は迅速に減速されねばならず、しかも端部で加速されねばならない、これ は機械構造内に大きいひずみを生じながら単位時間当りの一次薄板の送出量に振 り子運動が呼応するためである。従って、この機構は大体100m7分以下の送 出速さにおいてのみ用いられる。The pendulum must be decelerated quickly and then accelerated at the end; this is a change in the feed rate of the primary thin plate per unit time while creating a large strain in the machine structure. This is because the Riko movement responds. Therefore, this mechanism can be used for transport of approximately 100 m or less in 7 minutes. Used only for exit speed.
高度な振り子振動数を有する振り子機構のもう1つの欠点は、大きい表面積もも つ振り子機構の迅速な前後進運動により生ずる強い空気流である。この空気流は 基盤面に薄い一次薄板が析着するのを妨害する。Another disadvantage of pendulum mechanisms with high pendulum frequencies is the large surface area of the thighs. This is a strong airflow caused by the rapid back and forth movement of the pendulum mechanism. This air flow Prevents deposition of thin primary plates on the substrate surface.
従来技術ではこのように掘り子機構を用いて受取りコンベヤ上に重なり合う層状 にして薄い一次薄板を送給している。しかし、これらの従来技術は全てかなり欠 点がある:端部が平れでなく、材料の損失が大きい、また速さが遅すぎて所望の 能力を満足しない、減速力と加速力とが強く構成上大きい機械的応力を生ずる; 空気流の問題は一次薄板の析着を危くする。In conventional technology, the digging mechanism is used to collect overlapping layers on the receiving conveyor. A thin primary sheet is then fed. However, all these conventional techniques are quite lacking. There are points: the edges are not flat, there is a lot of material loss, and the speed is too slow for the desired The deceleration and acceleration forces are strong and cause large mechanical stresses due to the structure; Air flow problems compromise the deposition of the primary sheet.
本発明の目的はこれらの欠点を減らすか全く除くにあり、特に平らな端部をもつ 設定を正確に行なうこと、しかも高度に均質な薄板を設定すること、そしてまた その主要な特徴が特許請求の範囲第1項ならびに第9項に記載しであるその方法 ならびに装置を提供することによって、このことが達成されている。The object of the invention is to reduce or eliminate these disadvantages, in particular to It is important to perform the setting accurately and to set a highly homogeneous thin plate, and also to The method whose main features are as set out in claims 1 and 9 This has been achieved by providing a device as well.
本発明に係る好適実施態様においては、公知の駆動装置が用いられ、以後振り子 と称される振動式振り子コンベヤに対して、振り子運動の中央において一定の運 動速度を、そして振り子運動の両遠位端部においてはそれぞれシヌソイダル関数 的減少と増加をその速度に生ぜしめている。一定速さの期間は振り子の全揺動工 程の30ないし60%の範囲である。中央部分でも振り子の一定した速さは一次 薄板の送出速さに全面的にあるいはほとんより与えられる距離の約半分において 受取りコンベヤ面に接近して振り子が設定できる原因となっており、その結果、 受取りコンベヤ上に一次薄板の析着と固定とをかなりよ〈実施することを保証し ている。In a preferred embodiment of the invention, a known drive device is used, hereinafter the pendulum For a vibrating pendulum conveyor called a and the sinusoidal function at both distal ends of the pendulum motion, respectively. This is causing a decline and an increase in the rate of decline. During the period of constant speed, the pendulum oscillates completely. It is in the range of 30 to 60%. Even in the center, the constant speed of the pendulum is linear At approximately half of the distance given entirely or mostly to the sheet delivery speed. This causes the pendulum to be set close to the receiving conveyor surface, resulting in It is guaranteed that the deposition and fixing of the primary sheet on the receiving conveyor will be carried out in a very good manner. ing.
一定速さをもつ運動相の外側望城では、振り子はそれぞれシヌソイダル関数的に 駆動され増大する割合を減じ、一方では、振り子は振り子運動を続ける。振り子 の揺動運動の遠位端におけるそれぞれの増加割合の減少時における運動中に、少 なくとも、振り子の送出端は振り子運動の最終的運動相内で上昇するように設け られ立上り運動相では沈降するように設けられる。加速運動相のそれぞれの減速 時における振り子高さの変化により、位振り子の送出端が振り子の全揺動工程に わたって水平経路を画く場合に生ずる応力よりも小さい応力をこの機構に生ずる 。In the outer wall of the motion phase with constant speed, each pendulum has a sinusoidal function. Reduce the rate at which it is driven to increase, while the pendulum continues its pendulum motion. pendulum During the movement, at the distal end of the rocking movement the respective increase rate decreases, At least the delivery end of the pendulum is arranged to rise during the final phase of the pendulum movement. It is arranged so that it sinks during the rising motion phase. Deceleration of each phase of acceleration motion Due to the change in the pendulum height over time, the sending end of the pendulum changes over the entire swinging process of the pendulum. This creates a stress in the mechanism that is less than that created when drawing a horizontal path across the .
一定速さをもつ中央部分と減速ならびに加速の両速さをもつ2つの遠位部分とか ら成る振り子運動は、29aの共面すきまチェーン車の上を走る無端駆動チェー ンを用いて適切に得られる。かくして連結棒は振り子を駆動用チェーン上の搬送 体に連結する。チェーン車の中心距離は一定速さをもつ振り子運動の一部に呼応 し、しかも各車の半周長さは減速と加速の速さをもつ振り子運動に対応している 。A central part with a constant speed and two distal parts with both deceleration and acceleration speeds. The pendulum motion consisting of the endless drive chain running on the coplanar clearance chain wheel 29a can be obtained appropriately using The connecting rod thus transports the pendulum on the driving chain. Connect to the body. The center distance of the chain wheel corresponds to part of the pendulum motion with constant speed. Moreover, the half circumference length of each car corresponds to pendulum motion with deceleration and acceleration speeds. .
一定速さをもつ中央部分と減速ならびに加速の両速さをもつ2つの遠位部分とか ら成る振り子運動は、いわゆるフェルグソン歯車を用いて生ぜしめられ、この場 合、回転運動は楕円状歯車ホイールで伝達される。A central part with a constant speed and two distal parts with both deceleration and acceleration speeds. The pendulum motion consisting of the In this case, the rotational movement is transmitted by an elliptical gear wheel.
振り子の送出端は振り子運動の経路内で異なった形状の経路に沿って動くように 案内される。最も単純な実施態様は円弧状定角軌道であり、この軌道により軸受 の静止点周囲を振り子が揺動する。かかる実施態様においては、振り子の作動は 非常に正確で、約200m/分の送出速さを保つ、このことは、振り子の送出端 が非常に接近して受取りコンベヤに載置され、全姪動工程の中央点で最もコンベ ヤに近づき、その結果、送出された一次薄板は直ちに下層の送出綿薄板上に固定 され、かくして振り子運動で起される空気流の邪魔をうけずに留まる。という状 態を現出する。振り子運動の両遠位部分では、振り子の下方端は送出幅の約0. 1倍だけ上る。すなわち、送出端200cmの場合約20cm上り、端部の折れ 曲りに対して一層正確な位置にある。これは綿薄板の折り曲げ部が小さいことに よる。この実施態様のもう1つの利点は、振り子が比較的短かいことであって、 送出幅、すなわち約140ないし200cmに対してそのントの質量が小さく、 駆動装置内の応力が小さい、空気流による邪魔はまた振り子が短かいので軽減さ れる。The sending end of the pendulum moves along different shaped paths within the path of pendulum movement. You will be guided. The simplest implementation is an arcuate fixed-angle orbit, which allows the bearing to A pendulum swings around a stationary point. In such embodiments, the actuation of the pendulum is Very accurate and maintaining a delivery speed of approximately 200 m/min, this means that the delivery end of the pendulum are placed on the receiving conveyor very close together, with the most conveyor As a result, the delivered primary sheet is immediately fixed onto the lower delivered cotton sheet. and thus remains undisturbed by the airflow caused by the pendulum movement. situation manifest the state of affairs. In both distal portions of the pendulum motion, the lower end of the pendulum is approximately 0.0 mm of the delivery width. Only 1 times higher. In other words, if the sending end is 200 cm, there will be a rise of about 20 cm and a bend at the end. It is in a more accurate position relative to the bend. This is because the bent part of the cotton thin plate is small. evening. Another advantage of this embodiment is that the pendulum is relatively short, The mass of the tip is small relative to the delivery width, that is, about 140 to 200 cm, Stresses in the drive are low, and air flow disturbances are also reduced due to the short pendulum. It will be done.
この実施態様では、振り子は受取りコンベヤ上ゎづが5ないし10cmの接近点 において載置できるように調節可能であり、またこのように送出した綿−次薄板 が定角軌道の中央部分に入ると直ちに固定可使である。その結果、 1Is−次 薄板は平均化された端部となる。送出幅の約50%以上の一定速さにおいて、す なわち200cmでは、80%の最大振り子揺動及び送出幅の約75%の振り子 長さ、すなわち、150cmでは、振り子はその遠位点で約12%、すなわち2 4cm上る。In this embodiment, the pendulum has an approach point 5 to 10 cm above the receiving conveyor. It can be adjusted so that it can be placed on the As soon as it enters the central part of the fixed angle orbit, it becomes fixed and usable. As a result, 1Is-th The lamina will have an averaged edge. At a constant speed of approximately 50% or more of the delivery width, That is, at 200 cm, the maximum pendulum swing is 80% and the pendulum is approximately 75% of the delivery width. length, i.e. 150 cm, the pendulum at its distal point is about 12%, i.e. 2 Go up 4cm.
本発明のもう1つの好適実施態様では、振り子及びその送出端は、振り子揺動運 動の中央部分で、受取りコンベヤ上の一定高さで水平作動を強いられ、しかも最 外側位置においてこの位により上る。In another preferred embodiment of the invention, the pendulum and its delivery end are arranged in a pendulum oscillating motion. In the central part of the movement, horizontal movement is forced at a certain height above the receiving conveyor, and It rises more to this extent in the outer position.
上昇運動は振り子がその揺動運動の中央点を過ぎた後、何れの点におても始まる 、しかし振り子運動中減速相中最も遅れた位置で一次薄板にこのように実施れ、 この−次薄板は一定速さで振り子の送出端が送出され、この場合送出端の十分下 方位置で出され1次いでこの送出端は一次薄板の送出速さより遅い速さで作動さ れる。かくの如く上昇運動は、振り子運動の中央部分を過ぎた直後に最も早い時 点で開始され、振り子とその送出端とは次いで連続性円弧を画き、あるいは振り 子運動の遠位点に達する前の点において最も遅い時点で開始される。そして振り 子揺動には十分な空間が与えられていて上昇する振り子の下に空間がありこの空 間は制御下に堆積ループを置くためでありまた反転作動中に平らな端部を形成す るためである。The upward motion begins at any point after the pendulum passes the center point of its swinging motion. , but if carried out in this way on the primary plate at the most delayed position during the deceleration phase during the pendulum motion, The sending end of the pendulum is sent out at a constant speed, and in this case, the thin plate is placed well below the sending end. This delivery end is then operated at a speed slower than the delivery speed of the primary sheet. It will be done. As shown above, the upward movement is at its earliest just after passing the central part of the pendulum movement. starting at a point, the pendulum and its sending end then trace a continuous arc, or The child movement starts at the latest point before reaching the distal point. And swing There is enough space for the pendulum to swing, and there is space under the rising pendulum. The interval is to keep the deposition loop under control and also to form a flat end during the inversion operation. This is for the purpose of
送出端によって画かれた経路は直線状に上昇し、また円形の連続的な円弧状線、 もしくはこれらの各種の組合せである。The path drawn by the delivery end rises in a straight line, and also has a circular continuous arcuate line, Or various combinations of these.
各種の案内装置により、振り子及びその送出端が円形の送出経路をもつ自然な振 り子運動から偏向させられる。その瞬間からそこには自然の振り子運動からの偏 向がみられ、振り子の振動点は垂直に移動可能かあるいは送出端の揺動半径が変 動可能でなければならない。Various guiding devices allow the pendulum and its delivery end to oscillate naturally with a circular delivery path. deflected from the riko motion. From that moment on, there is a deviation from the pendulum movement of nature. The pendulum's oscillation point can be moved vertically, or the oscillation radius of the sending end can be changed. Must be movable.
主に水平な中央部分と円弧状端末部分とから成る送出定角軌道が望まれ、*り千 円の軸受に設けた腕は例えば下方端から成り、この下方端は振り子爵側の軸受上 に錠軸結合され、かくして振り子をして大体水平の経路を画かす、この作動部分 中、振り子の振動点は沈降/上昇をする。振動点はその配設が停止点あるいは他 の停止点に達するようになっており、この他の停止点では振り子はその最外側領 域で上昇運動をし、反転作動中に同一領域で沈降運動をそれぞれ行なう、振り千 円の軸受、に対する腕の装着部の配設は、振り子がこの段階で腕に対して振動状 態となる如く例えばフォーク軸受などを用い設定する。振り子の連結棒頂部と振 り子の高さ位置案内用腕との間にばねが適当に設けられ、これにより加速と減速 の各力が、振り子の双方の遠位点で部分的に平行状態に保たれる。A fixed-angle delivery trajectory consisting of a mainly horizontal central portion and an arcuate terminal portion is desired; The arm provided on the circular bearing consists, for example, of a lower end, which lower end is attached to the upper part of the bearing on the pendulum side. This actuating part is connected to the lock shaft and thus pendulums in a generally horizontal path. During the period, the pendulum's oscillation point sinks/rises. The vibration point is located at a stop point or other The pendulum reaches a stopping point in its outermost region at any other stopping point. Furisen, which performs an upward movement in the area and a downward movement in the same area during the reversal operation. The arrangement of the arm attachment part relative to the circular bearing is such that the pendulum vibrates relative to the arm at this stage. For example, use a fork bearing or the like so that the The top of the pendulum connecting rod and the swing A spring is appropriately installed between the lever and the height position guide arm, which allows acceleration and deceleration. forces are kept partially parallel at both distal points of the pendulum.
振り子の作動はまた、例えば固定の案内により案内されるようになっていて、こ の案内は中実軸線に関して対称図形的に設けられ、この軸線に沿って振り千円の 軸受にホイールが装着され、あるいは摺動体が作動可能に設けられる。送出端の 定角軌道は、かくして、案内の形状に呼応する。送出端の上方にある案内の高さ は形状及び質量の大きさにより決められる。The operation of the pendulum can also be guided, for example by a fixed guide, The guide is provided symmetrically with respect to the solid axis, and the 1,000 yen guide is provided along this axis. A wheel is attached to the bearing, or a sliding body is movably provided. delivery end The constant angle trajectory thus corresponds to the shape of the guide. Height of the guide above the delivery end is determined by the shape and mass size.
振り子の振動点は交互に静止状態となり得るのであり、一方、送出端は振動点に 関して半径方向に可能である。The oscillating points of the pendulum can alternately be at rest, while the sending end can be at the oscillating point. radially possible.

第1図において1図の右側に(A)の場合を示し、この(A)では、一定速ささ の周期中及び減速及び加速速さの周期の双方の周期中にある振り子が点Pの周囲 を振動しており、P点はこの(A)では静止しており、送出端は円弧を画く、振 り子は低速チェーンにより案内装置りを用いて駆動される。連結棒■は搬送体上 の軸受に装着されT点で駆動チェーンに連結され、KA点で振り子機構に連結さ れる。駆動チェーン内に1〜12の各点がマークされており、これにより点1と 7とは振り子の中央の点を示し、4とlOとは振り子の遠位点、モして12と2 とは、それぞれ6と8と共に定速領域の限界を示す、連結棒のT点が1の位置に あると、振り子は振動点Pと1 (A)で示される送出端の位置にて懸架される 。連結棒が定速で1から2へ動くと、振動点Pは静止しているので送出端は円弧 を画く、振り子が2から4へ、減速して動くと点4で運動方向が変化し1点4か ら6へ加速し、送出端が上昇及び沈降の円弧を画いて動く間、点6から7に動く 、振り子上の締め付は部KAの駆動装HDに関する位置に依り、多かれ少なかれ 対称図形が形成される。すなわち1点3と5それから2と6とはそれぞれ互いに 若干偏向する。これは大ざっばな図に見られる。振り子は遠位点4で約24cm 上昇する。これは、また1/10の縮尺で画かれた図から明らかであり折り返し 点での一次薄板の制御されたループを形成する。送出端と受取りコンベヤSAと の間の距離が小さいことにより、また、送出端の送出速さと振動速さとにより、 送出された一次薄板は迅速に基盤に固定・され、この基盤は、また、大ざっばな 図に見られる0点7から1への振り子の運動は点lから7への運動の反転と考え られるので、示していない。In Figure 1, case (A) is shown on the right side of Figure 1, and in this (A), the speed is constant. The pendulum during both the period of , and the period of deceleration and acceleration speed is around point P. The point P is stationary in this (A), and the sending end draws an arc and is oscillating. The rover is driven by a low speed chain using a guiding device. The connecting rod ■ is on the conveyor It is attached to the bearing and connected to the drive chain at point T, and connected to the pendulum mechanism at point KA. It will be done. Each point from 1 to 12 is marked in the drive chain, which allows points 1 and 12 to be marked. 7 indicates the center point of the pendulum, 4 and lO are the distal points of the pendulum, and 12 and 2 means that the T point of the connecting rod is at position 1, which together with 6 and 8 respectively indicate the limit of the constant speed region. , the pendulum is suspended at the vibration point P and the sending end position indicated by 1 (A). . When the connecting rod moves from 1 to 2 at a constant speed, the vibration point P remains stationary, so the delivery end forms an arc. When the pendulum moves from 2 to 4 and decelerates, the direction of movement changes at point 4, and 1 point 4. accelerates from point 6 to point 6 and moves from point 6 to point 7 while the delivery end moves in an arc of rise and fall. , the tightening on the pendulum may be more or less depending on the position of part KA with respect to drive unit HD. A symmetrical figure is formed. That is, 1 point 3 and 5, and 2 and 6 are each other. Slightly deflected. This can be seen in the rough diagram. The pendulum is approximately 24 cm at distal point 4 Rise. This is also clear from the figure drawn at a scale of 1/10, and the Forming controlled loops of the primary lamina at points. Sending end and receiving conveyor SA Due to the small distance between them, and due to the delivery speed and vibration speed of the delivery end, The delivered primary thin plate is quickly fixed to the base, and this base is also roughly The movement of the pendulum from point 0 7 to 1 seen in the figure is considered to be the reversal of the movement from point l to 7. It is not shown because it can be
第1図の左側は(B)の場合を示しており、この場合は、振り子はその定速周期 中振り子の送出端が受取りコンベヤl上一定の高さで作動し、減速ならびに加速 運動中は、円形経路に沿って動く、振り子の中央点、7においては、振り子の振 動点は、P′にあるが、点8まで動かされる間に点Pまで沈み、かくして、送出 端は水平線に沿って動く0点8から10への減速相及び点10から12への加速 相においては、振動点Pは静止して保たれ、送出端は円弧を画く0図から分るよ うに、受取りコンベヤSRは(A)の場合より高く位置しており、これは振り子 の振動点が(B)の場合の中心位置よりも高いからである。The left side of Figure 1 shows the case (B), in which the pendulum has a constant speed period of The sending end of the middle pendulum operates at a constant height above the receiving conveyor, causing deceleration and acceleration. During the motion, the center point of the pendulum, 7, moves along a circular path. The moving point is at P', but while being moved to point 8, it sinks to point P, thus sending The edges move along the horizontal line 0 Deceleration phase from point 8 to 10 and acceleration from point 10 to 12 In the phase, the vibration point P is kept stationary, and the sending end is an arc, as can be seen from the diagram 0. uni, the receiving conveyor SR is located higher than in case (A), and this is due to the pendulum. This is because the vibration point of is higher than the center position in case (B).
振り子はその最高位において約16cm上昇する。この位置は図に示すとおりで ある。薄板のループ化はこの場合具合よく制御されるのであって、それは−次薄 板の基盤に到る距離が短いためであり、特に点7〜8及び12〜lの間が短く、 しかもこれらの距離における送出端の送出速さと振動速さとの間の同期化による からである。The pendulum rises approximately 16 cm at its highest point. This position is as shown in the diagram. be. The looping of the thin plate is well controlled in this case, and it is This is because the distance to the base of the board is short, especially between points 7 and 8 and 12 and l. Furthermore, due to the synchronization between the delivery speed and vibration speed of the delivery end at these distances, It is from.
振り子の送出端をその大部分において水平に作動させるには、図示の場合は振り 子の揺動の50%であるが、振動点はPoからP点に移らねばならない、つまり 特別な寸法が必要である。かかる構成における好適実施態様2つを第2図及び@ 3図の各図にそれぞれ示しである。To operate the pendulum delivery end horizontally over most of its length, the pendulum For 50% of the child's oscillation, the oscillation point must move from Po to P point, that is. Special dimensions required. Two preferred embodiments of such a configuration are shown in FIG. Each figure in FIG. 3 is shown.
f:t42図及び第3図の各図は鉱滓綿薄板生産用機械の振り子部分ならびに関 連の駆動機構を示す、−次薄板の受取りコンベヤは1であり、関連の振り子穴コ ンベヤは2であり、2つの相対するコンベヤは2aと2bであり、送出端の伝導 ローラは3aと3bでそれぞれ示す。Figure f:t42 and Figure 3 show the pendulum part and related parts of the machine for producing slag cotton sheets. The receiving conveyor for the next thin plate is 1, and the associated pendulum hole The conveyor is 2, the two opposing conveyors are 2a and 2b, and the conduction at the delivery end is The rollers are designated 3a and 3b respectively.
受取りコンベヤは4で示してあり、駆動機構は5で、駆動機構の2つの車は5a と5bで、また連結棒は6で示す、工ないし6までの部品は多賀位に第2図及び 第3図の各図に対応し、同じ番号で指示しである。The receiving conveyor is shown at 4, the drive mechanism is at 5, and the two wheels of the drive mechanism are at 5a. and 5b, and the connecting rod is shown as 6. Parts from 1 to 6 are shown in Figure 2 and at Taga position. They correspond to each of the figures in FIG. 3 and are designated by the same number.
第2図において、振り子の運動を案内装数内に伝える輪は7で示してあり、振り 子コンベヤに固定される輪の軸線は7aで示す0輪7が沿って走り、しかも送出 端の定角軌道を決定する案内は9で示す、振り子穴コンベヤの送出端は10とし である。In Figure 2, the ring that transmits the motion of the pendulum to the guide gear is shown as 7, and The axis of the wheels fixed to the child conveyor is along which the zero wheel 7 shown as 7a runs, and The guide for determining the constant angular trajectory at the end is indicated by 9, and the delivery end of the pendulum hole conveyor is indicated by 10. It is.
鉱滓綿薄板を生産する場合、−次薄板は受取りコンベヤl上に送出されて更にコ ンベヤ2aと2bとの間を走行して振り子機構2内に入り、送出端1oから出さ れる。−次薄板が伝導ローラ3aと3bとの間に送入されるとき、振り子は前後 方向に揺動する。連結棒が駆動輪5aと5bとの間の距#blを動くとき、車7 は定速運動をうけ、同時に、案内9の平坦部分を作動する。これにより、伝導ロ ーラ3aと3bとは受取りコンベヤ上一定の高さにおいて距離Blを覆う、連結 棒が駆動輪の円周上を距#b2に等しい長さだけ動くとき、輪7は案内9の上方 へ曲った端部を越えて動き、振り子の送出端は距#B2にわたって対応する円弧 を画く、案内9の位置は所望の運動学的幾何学により決められる。振り子の振動 点22は中央の振り子運動の軌跡を示す線に沿って変換可能であり、−次薄板の 受取りコンベヤlは、振り子の送出端の運動に従って垂直に作動できるように関 節により軸受上に装着される。When producing slag cotton sheets, the second sheet is sent onto a receiving conveyor and further coated. It travels between the conveyors 2a and 2b, enters the pendulum mechanism 2, and comes out from the delivery end 1o. It will be done. - When the next thin plate is fed between the conduction rollers 3a and 3b, the pendulum swings back and forth. swing in the direction. When the connecting rod moves the distance #bl between the drive wheels 5a and 5b, the car 7 is subjected to constant velocity movement and at the same time actuates the flat part of the guide 9. This allows conduction The rollers 3a and 3b are connected to cover a distance Bl at a certain height above the receiving conveyor. When the rod moves on the circumference of the drive wheel by a length equal to distance #b2, the wheel 7 is above the guide 9. moving over the bent end, the sending end of the pendulum follows the corresponding arc over distance #B2 , the position of the guide 9 is determined by the desired kinematic geometry. pendulum vibration Point 22 is transformable along the line indicating the locus of the central pendulum motion, and is The receiving conveyor l is connected so that it can operate vertically according to the movement of the delivery end of the pendulum. It is mounted on the bearing by a knot.
第3図は本発明に係る振り子のもう1つの好適実施態様を示す、腕20の下端は 振動の中心線上の振り子の外側にある軸受上に固定され、その上端部は振り子上 の連結棒6の軸受点8に設けたフォーク軸受上に装着される。軸受点8は腕の上 端においてフォーク21内で走行するように設けられる。振り子の振動点22は その運動の中心線に沿って垂直に交換可能であり、−次薄板の受取りコンベヤl は、前出の場合と同様に、振り子の運動に垂直に従うことができるように関節に よって軸受上に装着される。連結棒が、駆動輪の間の水平部分にわたって作動す るときに、振り子は1つの角度的位置に引き込まれ、一方、振動点は下方に動き 、定速周期の絆点にある停止点23に到達するまで動く、この停止点は振動点が 更に下るのを防止し、振り子はこれまで固定されていた振動点Pの周りに揺動を 強いられる。この減速運動中、締めつけ点8はフォーク21内を上方に変位され 、かくして、振り子が円弧状線に沿って上昇するのを防ぐことがなくなる。統〈 加速相中に振り子は下方に揺動し送出端lOは同様な円弧を画き、一方では、締 めつけ点8が同時にフォーク21の底部に向って変位させられる。同様な運動が 相対向する位置において繰り返される。FIG. 3 shows another preferred embodiment of the pendulum according to the invention, in which the lower end of the arm 20 is It is fixed on a bearing on the outside of the pendulum on the center line of vibration, and its upper end is placed on the pendulum. is mounted on the fork bearing provided at the bearing point 8 of the connecting rod 6. Bearing point 8 is on the arm It is provided to run within the fork 21 at the end. The pendulum's vibration point 22 is It is exchangeable vertically along the center line of its movement, and - the receiving conveyor of the next thin plate l , as in the previous case, at the joints so that they can follow the pendulum motion perpendicularly Therefore, it is mounted on the bearing. The connecting rod runs across the horizontal section between the drive wheels. When the pendulum is pulled into one angular position, the point of oscillation moves downward. , moves until it reaches the stopping point 23 at the bond point of the constant speed cycle, this stopping point is the vibration point. To prevent the pendulum from falling further, the pendulum is allowed to oscillate around the previously fixed oscillation point P. Be strong. During this deceleration movement, the tightening point 8 is displaced upward within the fork 21. , thus preventing the pendulum from rising along the arcuate line. Tong〈 During the acceleration phase, the pendulum swings downward and the delivery end lO traces a similar arc, while the tightening The plating point 8 is simultaneously displaced towards the bottom of the fork 21. A similar movement Repeated in opposite positions.
ばねを中心軸線と腕20との間に設は振り子の振動により生じた減速及び加速の 部分を取り出すことは有益である。A spring is installed between the central axis and the arm 20 to prevent deceleration and acceleration caused by the vibration of the pendulum. It is beneficial to take out the pieces.
第2図及び3の各図に示す実施態様のそれぞれが示す振り子運動では、水平もし くは実質上水平に近い送出運動が定速をもつ運動相と合致しており、しかも上昇 及び沈降のそれぞれの運動が減速及び加速のそれぞれの速さの相と合致している 。送出端の制御された定角軌道は円形の定角軌道から偏しているが、定速b1の 周期あるいは減速もしくは加速運動b2の周期を通じて如何なる点においても開 始されるようにもちろん調節される。In the pendulum motion shown in each of the embodiments shown in FIGS. 2 and 3, the horizontal In particular, the nearly horizontal delivery motion coincides with a motion phase with constant velocity, and and the respective motions of sedimentation are consistent with the respective velocity phases of deceleration and acceleration. . The controlled constant angle trajectory of the delivery end deviates from the circular constant angle trajectory, but the constant speed b1 open at any point throughout the period or period of deceleration or acceleration motion b2. Of course adjusted to start.
上述した如く、減速力と加速力とは先行技術で用いた方法におけるよりも小さい 、そしてこれは部分的に送出側における上昇運動に依るものであり、また部分的 に質量の小さい小形の振り子に起因している。As mentioned above, the deceleration and acceleration forces are smaller than in the methods used in the prior art. , and this is partly due to the upward movement on the delivery side, and partly due to the upward movement on the delivery side. This is caused by a small pendulum with a small mass.
出業者は、上述の実施態様にいくつかの異なる方法を追加することによって、最 高位において上昇させ、拙勤の中央部分の運動相においては一定速度をもつよう に振り子の運動をさせるという本発明の考えを実施することは回部であるという ことは明らかである。By adding several different methods to the implementation described above, the It rises at a high level and has a constant speed during the movement phase of the central part of the movement. It is said that implementing the idea of the present invention of making a pendulum move is a rotation part. That is clear.
