Description

本発明は、接続装置と、接続装置を介して混練装置と駆動装置とを接続した混練設備に関するものである。   The present invention relates to a connecting device and kneading equipment in which a kneading device and a driving device are connected via the connecting device.

従来より、ゴム，プラスチック等の混練物を混練する混練装置として特許文献１に開示されているものがある。この混練装置は双腕式であって、双腕式混練装置の近傍に配置された駆動装置によって駆動されるものである。
詳しくは、この混練装置には外部へ突出する入力軸が設けられ、駆動装置には外部へ突出する出力軸が設けられている。そして、混練装置の入力軸と駆動装置の出力軸とは、ギアカップリング部を有する接続装置によって接続されるようになっており、この接続によって混練装置を駆動している。 Conventionally, there is a device disclosed in Patent Document 1 as a kneading device for kneading a kneaded material such as rubber and plastic. This kneading apparatus is of a double arm type, and is driven by a driving device arranged in the vicinity of the double arm type kneading apparatus.
Specifically, the kneading device is provided with an input shaft that protrudes to the outside, and the drive device is provided with an output shaft that protrudes to the outside. The input shaft of the kneading device and the output shaft of the driving device are connected by a connecting device having a gear coupling portion, and the kneading device is driven by this connection.

JP 2004-313927 A

従来の接続装置は、ギアカップリング部のギアの摩耗などによって交換が必要になることがある。
しかしながら、混練装置ではカップリング部を交換する場合、入力軸と出力軸とが近接している状態においてはギアカップリング部を取り外すことができない構造であるために、一旦、混練装置又は駆動装置の少なくともどちらか一方を軸方向に動かして、入力軸と出力軸とを遠ざけた上でギアカップリング部を両軸から取り外すようにしなければならず、非常に交換作業が面倒であった。混練装置又は駆動装置を完全に元通りの位置に戻す作業も非常に煩雑であった。 The conventional connection device may need to be replaced due to wear of the gear of the gear coupling portion.
However, in the kneading device, when the coupling portion is replaced, the gear coupling portion cannot be removed when the input shaft and the output shaft are close to each other. At least one of them must be moved in the axial direction so that the input shaft and the output shaft are moved away from each other and the gear coupling portion must be removed from both shafts. The work of returning the kneading device or the driving device to the original position completely was also complicated.

そこで、本発明は、上記問題点に鑑み、混練装置等の被駆動装置又は駆動装置を移動させなくても簡単にギアカップリング部の交換が可能な接続装置と、接続装置を介して混練装置と駆動装置と接続した混練設備とを提供することを目的とする。   Therefore, in view of the above problems, the present invention provides a connection device that allows easy replacement of a gear coupling portion without moving a driven device such as a kneading device or a driving device, and a kneading device via the connection device. And a kneading facility connected to the driving device.

前記目的を達成するために、本発明は次の手段を講じた。即ち、駆動装置の出力軸と被駆動装置の入力軸とを接続するギアカップリング部を有する接続装置において、前記ギアカップリング部は、前記被駆動装置の入力軸及び前記駆動装置の出力軸に対してそれぞれ個別に嵌合され且つ外周面に第１ギアを有する一組の第１筒体と、この一組の第１筒体に遊嵌すると共に、一組の第１ギアにそれぞれ個別に噛合する第２ギアを内周面に有する一組の第２筒体と、この一組の第２筒体の間で着脱自在に設けられ且つ両第２筒体を連結する連結体とを有し、前記第２筒体及び前記連結体が入力軸及び出力軸の両端面間から抜き取り自在となるように、当該第２筒体及び連結体それぞれの軸方向長さが、両端面間の距離よりも短く設定されている点にある。   In order to achieve the above object, the present invention has taken the following measures. That is, in the connecting device having a gear coupling portion that connects the output shaft of the driving device and the input shaft of the driven device, the gear coupling portion is connected to the input shaft of the driven device and the output shaft of the driving device. A set of first cylinders that are individually fitted to each other and have a first gear on the outer peripheral surface, and are loosely fitted to the set of first cylinders, and individually to the set of first gears. A pair of second cylinders having a second gear to be engaged on the inner peripheral surface, and a connecting body that is detachably provided between the pair of second cylinders and connects the second cylinders. The axial length of each of the second cylinder and the connecting body is the distance between both end faces so that the second cylinder and the connecting body can be extracted from between both end faces of the input shaft and the output shaft. It is in the point set shorter than.

これによれば、混練装置又は駆動装置を動かず混練装置と駆動装置を所定の位置に固定している状態のままで、第２筒体及び連結体を抜き取ることができ、非常に簡単に第２筒体を交換することができる。言い換えれば、混練装置と駆動装置との相対位置を変えずに交換ができ、混練装置と駆動装置との再位置決めも不要である。
前記第１筒体が入力軸及び出力軸の両端面間から抜き取り自在となるように、当該第１筒体の軸方向長さが、両端面間の距離よりも短く設定されていることが好ましい。
これによれば、混練装置又は駆動装置を動かさなくても、第１筒体を抜き取ることができ、非常に簡単に第１筒体を交換することができる。 According to this, the second cylinder and the connecting body can be pulled out with the kneading device and the driving device fixed in place without moving the kneading device or the driving device. Two cylinders can be exchanged. In other words, the kneading device and the driving device can be exchanged without changing the relative positions, and repositioning of the kneading device and the driving device is not necessary.
It is preferable that the axial length of the first cylinder is set to be shorter than the distance between both end faces so that the first cylinder can be extracted from between both end faces of the input shaft and the output shaft. .
According to this, even if it does not move a kneading apparatus or a drive device, a 1st cylinder can be extracted and a 1st cylinder can be replaced | exchanged very easily.

前記第２ギアの硬度が前記第１ギアの硬度よりも低く設定されていることが好ましい。
これによれば、第２筒体の第２ギアよりも第１筒体の第１ギアの摩耗を抑制することによって、第１筒体の交換頻度を減らすことができる。
前記ギアカップリング部は、第１ギア及びこれと噛合する第２ギアが回転に伴って歯幅方向に相対的に摺動自在とすべく、前記第１ギアの頂部が歯幅方向に曲線的に形成されていることが好ましい。
前述した接続装置を介して、入力軸を有し且つ被駆動装置の１つである混練装置と前記入力軸に対応する出力軸を有する前記駆動装置とが接続され、当該対応する入力軸及び出力軸に前記ギアカップリング部が設けられていることが好ましい。 It is preferable that the hardness of the second gear is set lower than the hardness of the first gear.
According to this, the replacement frequency of a 1st cylinder can be reduced by suppressing abrasion of the 1st gear of a 1st cylinder rather than the 2nd gear of a 2nd cylinder.
The gear coupling portion is configured such that the top portion of the first gear is curved in the tooth width direction so that the first gear and the second gear meshing therewith can be relatively slidable in the tooth width direction as the gear rotates. It is preferable to be formed.
The kneading device having an input shaft and one of the driven devices is connected to the driving device having the output shaft corresponding to the input shaft via the connecting device, and the corresponding input shaft and output are connected. It is preferable that the gear coupling portion is provided on the shaft.

前記混練装置が２本の入力軸を有し、前記駆動装置が前記２本の入力軸のそれぞれに対応する２本の出力軸を有しており、当該対応する入力軸及び出力軸毎に前記ギアカップリング部が設けられていることが好ましい。   The kneading device has two input shafts, and the driving device has two output shafts corresponding to the two input shafts. It is preferable that a gear coupling portion is provided.

本発明によれば、混練装置等の被駆動装置又は駆動装置を移動させなくても簡単にギアカップリング部の交換をすることができる。   According to the present invention, the gear coupling portion can be easily replaced without moving a driven device such as a kneading device or a driving device.

以下、本発明の実施の形態を図面を参照して説明する。
図１は、駆動装置と被駆動装置とを接続した設備の正面図である。図２は、駆動装置と被駆動装置とを接続した設備の平面図である。図１、２に示す被駆動装置は、例えば、ゴム，プラスチック等の混練物を混練する混練装置１であって、同図に示す設備は混練設備Ａである。
混練設備Ａは、混練装置１と、駆動装置２と、混練装置１と駆動装置２とを接続する接続装置６を有している。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of equipment in which a driving device and a driven device are connected. FIG. 2 is a plan view of equipment in which a driving device and a driven device are connected. The driven apparatus shown in FIGS. 1 and 2 is, for example, a kneading apparatus 1 for kneading a kneaded material such as rubber and plastic, and the equipment shown in FIG.
The kneading equipment A includes a kneading device 1, a driving device 2, and a connecting device 6 that connects the kneading device 1 and the driving device 2.

図１，２に示すように、混練装置１の一例である密閉式混練装置は設置床Ｆ等に設置される定置型ものである。また、駆動装置２は設置床Ｆ等に設置される定置型ものである。
図２に示すように、例えば、設置床Ｆでは、密閉式混練装置１を設置する第１設置エリア３が決められ、駆動装置２を設置する第２設置エリア４が決められている。
そして、密閉式混練装置１は第１設置エリア３内に収まるように設置され、駆動装置２は第２設置エリア４内に収まるように設置される。設置床Ｆにおいて、第１設置エリア３と第２設置エリア４とは並列に設けられている。 As shown in FIGS. 1 and 2, the closed kneading apparatus as an example of the kneading apparatus 1 is a stationary type installed on the installation floor F or the like. The driving device 2 is a stationary type installed on the installation floor F or the like.
As shown in FIG. 2, for example, on the installation floor F, a first installation area 3 in which the closed kneading device 1 is installed is determined, and a second installation area 4 in which the drive device 2 is installed is determined.
The closed kneading device 1 is installed so as to be accommodated in the first installation area 3, and the driving device 2 is installed so as to be accommodated in the second installation area 4. In the installation floor F, the first installation area 3 and the second installation area 4 are provided in parallel.

第１設置エリア３に設置された密閉式混練装置１と第２設置エリア４に設置された駆動装置２とはギアカップリング部５を有する接続装置６によって接続される。
図３に示すように、密閉式混練装置１は、ゴム，プラスチック等の混練物を混練するもので、密閉状となる混練室１０と、この混練室１０内に収容された混練物を回転により混練する２本のロータ１１と、前記混練室１０の上方に設けられ混練物を投入するホッパー１２とを有している。
ホッパー１２には被混練物を添加剤等と共に投入可能な投入口１３が設けられている。ホッパー１２内には、被混練物を混練室１０側へ押し込むフローティングウエイト１４が昇降自在に設けられている。混練室１０には、混練物を外部へ取り出すためのドロップドア１５が設けられている。 The closed kneading device 1 installed in the first installation area 3 and the drive device 2 installed in the second installation area 4 are connected by a connection device 6 having a gear coupling portion 5.
As shown in FIG. 3, the closed kneading apparatus 1 kneads a kneaded product such as rubber and plastic, and rotates the kneaded chamber 10 in a sealed state and the kneaded product stored in the kneading chamber 10 by rotation. It has two rotors 11 for kneading and a hopper 12 provided above the kneading chamber 10 for charging the kneaded material.
The hopper 12 is provided with an insertion port 13 through which an object to be kneaded can be added together with additives. A floating weight 14 for pushing the material to be kneaded toward the kneading chamber 10 is provided in the hopper 12 so as to be movable up and down. The kneading chamber 10 is provided with a drop door 15 for taking out the kneaded material to the outside.

図２に示すように、それぞれのロータ１１には当該ロータ１１を回転させるための入力軸１６が設けられている。各入力軸１６は、混練室１０の側方から外部に向けて同一方向に突出している。
駆動装置２は、密閉式混練装置１を駆動するもので、減速機１７と駆動モータ１８とにより構成されている。減速機１７は、駆動モータ１８の動力を２系統に分けて密閉式混練装置１のそれぞれのロータ１１を互いに異なる方向に回転させるものである。詳しくは、減速機１７の一方からは２本の出力軸１９が外部へと突出しており、２本の出力軸１９の回転方向が異なる。 As shown in FIG. 2, each rotor 11 is provided with an input shaft 16 for rotating the rotor 11. Each input shaft 16 projects in the same direction from the side of the kneading chamber 10 toward the outside.
The driving device 2 drives the hermetic kneading device 1, and includes a speed reducer 17 and a driving motor 18. The speed reducer 17 divides the power of the drive motor 18 into two systems and rotates the respective rotors 11 of the closed kneading apparatus 1 in different directions. Specifically, two output shafts 19 protrude from one side of the speed reducer 17 to the outside, and the rotation directions of the two output shafts 19 are different.

以上、密閉式混練装置１及び駆動装置２で混練物を混練するには、まず、投入口１３から被混練物を添加剤等とともに投入し、フローティングウエイト１４の押し込み作用によって、被混練物及び添加剤等を密閉状態の混練室１０内に圧入する。
次に、混練室１０を密閉した状態で駆動装置２を駆動させる。このとき、駆動装置２の出力軸１９の動力が接続装置６を介して入力軸１６に伝達され、ロータ１１が回転する。各ロータ１１は、混練室１０の内壁を掃くようにして回転することで、当該混練室１０内に圧入された被混練物を添加剤等とともに混練する。密閉式混練装置１では、混練終了後は、ドロップドア１５を開き、混練物を外部に排出することができる。 In order to knead the kneaded material with the closed kneading device 1 and the driving device 2, first, the material to be kneaded is added together with the additive from the charging port 13, and the material to be kneaded and the added material are added by the pushing action of the floating weight 14. An agent or the like is press-fitted into the sealed kneading chamber 10.
Next, the driving device 2 is driven with the kneading chamber 10 sealed. At this time, the power of the output shaft 19 of the drive device 2 is transmitted to the input shaft 16 via the connection device 6, and the rotor 11 rotates. Each rotor 11 rotates so as to sweep the inner wall of the kneading chamber 10, thereby kneading the material to be kneaded that has been press-fitted into the kneading chamber 10 with an additive or the like. In the closed kneading apparatus 1, after the kneading is completed, the drop door 15 can be opened and the kneaded material can be discharged to the outside.

以下、密閉式混練装置１と駆動装置２とを接続する接続装置６について詳しく説明する。
図４〜６に示すように、接続装置６は、密閉式混練装置１の入力軸１６と駆動装置２の出力軸１９とを接続するギアカップリング部５と、このギアカップリング部５のギア２４に対して潤滑する潤滑部４６とを有している。
ギアカップリング部５は歯車形継手で構成され、密閉式混練装置１の入力軸１６と駆動装置２の出力軸１９とが互いに偏心している状態で互いの軸を接続することができる。 Hereinafter, the connection device 6 that connects the closed kneading device 1 and the driving device 2 will be described in detail.
As shown in FIGS. 4 to 6, the connection device 6 includes a gear coupling portion 5 that connects the input shaft 16 of the hermetic kneading device 1 and the output shaft 19 of the drive device 2, and the gear of the gear coupling portion 5. And a lubricating portion 46 that lubricates 24.
The gear coupling portion 5 is constituted by a gear-type joint, and can connect the shafts in a state where the input shaft 16 of the closed kneading device 1 and the output shaft 19 of the drive device 2 are eccentric from each other.

ギアカップリング部５は、２つに分割されるような構成を有していて、第１分割体２０と、第２分割体２１と、この第１分割体２０と第２分割体２１とを連結する連結体２２とを有したものとなっている。
第１分割体２０及び第２分割体２１は、それぞれ筒状の第１筒体２５と、筒状の第２筒体２６とを有している。第１筒体２５の外周面には第１のギア２７（以降、外歯２７ということがある）が形成されており、内周面にはキー溝２８が形成されている。
第１分割体２０の第１筒体２５には、駆動装置２の出力軸１９を挿入する挿入孔２９が形成されており、当該挿入孔２９に出力軸１９が嵌め込まれている。出力軸１９の外周面に形成されているキー溝２８’及びキー溝２８に固定具２８ａを嵌め込むことで出力軸１９は第１筒体２５と共に一体回転自在に固定されている。また、第１分割体２０の軸方向一方（連結体２２側）には、挿入孔２９を塞ぐようにプレート３０が締結具３０ａを介して取り付けられている。 The gear coupling portion 5 has a configuration that is divided into two parts. The first divided body 20, the second divided body 21, and the first divided body 20 and the second divided body 21 are divided into two parts. It has the connection body 22 to connect.
Each of the first divided body 20 and the second divided body 21 has a cylindrical first cylindrical body 25 and a cylindrical second cylindrical body 26. A first gear 27 (hereinafter sometimes referred to as an external tooth 27) is formed on the outer peripheral surface of the first cylinder 25, and a key groove 28 is formed on the inner peripheral surface.
An insertion hole 29 for inserting the output shaft 19 of the drive device 2 is formed in the first cylinder 25 of the first divided body 20, and the output shaft 19 is fitted in the insertion hole 29. The output shaft 19 is fixed together with the first cylinder 25 so as to be integrally rotatable by fitting a fixing tool 28 a into the key groove 28 ′ and the key groove 28 formed on the outer peripheral surface of the output shaft 19. Moreover, the plate 30 is attached to one axial direction side (connecting body 22 side) of the 1st division body 20 via the fastener 30a so that the insertion hole 29 may be plugged up.

第２分割体２１の第１筒体２５には、密閉式混練装置１の入力軸１６を挿入する挿入孔４９が形成されており、当該挿入孔４９に入力軸１６が嵌め込まれている。入力軸１６の外周面に形成されているキー溝２８’及びキー溝２８に固定具を嵌め込むことで、入力軸１６は第１筒体２５と共に一体回転自在に固定されている。また、入力軸１６の軸方向先端（連結体２２側）には、プレート３２が締結具３２ａを介して取り付けられている。
第２筒体２６は、第１筒体２５よりも外径が大なるもので、第２筒体２６の内周面には外歯２７と噛合う第２のギア（以降、内歯３３ということがある）が形成されている。 An insertion hole 49 into which the input shaft 16 of the hermetic kneading apparatus 1 is inserted is formed in the first cylindrical body 25 of the second divided body 21, and the input shaft 16 is fitted into the insertion hole 49. The input shaft 16 is fixed together with the first cylinder 25 so as to be integrally rotatable by fitting a fixing tool into the key groove 28 ′ and the key groove 28 formed on the outer peripheral surface of the input shaft 16. Moreover, the plate 32 is attached to the axial direction front-end | tip (connecting body 22 side) of the input shaft 16 via the fastener 32a.
The second cylindrical body 26 has an outer diameter larger than that of the first cylindrical body 25, and a second gear (hereinafter referred to as an internal tooth 33) that meshes with the external teeth 27 on the inner peripheral surface of the second cylindrical body 26. May be formed).

第２筒体２６の内歯３３の硬度は第１筒体２５の外歯２７の硬度よりも低く設定されている。これにより、第２筒体２６の内歯３３を第１筒体２５の外歯２７よりも早く摩耗させることができる。即ち、抜き取りをする第２筒体２６を選択的に摩耗させている（言い換えれば、第１筒体２５の外歯２７の摩耗を遅らせる）。
外歯２７及び内歯３３の形状は入力軸１６と出力軸１９との偏心による外歯２７と内歯３３の摺動を考慮した形状とされている。例えば、外歯２７は、図５に示す断面側面視で山部、即ち、頂部が歯幅方向に円弧状等となっている。 The hardness of the inner teeth 33 of the second cylinder 26 is set lower than the hardness of the outer teeth 27 of the first cylinder 25. Thereby, the inner teeth 33 of the second cylinder 26 can be worn faster than the outer teeth 27 of the first cylinder 25. That is, the second cylinder 26 to be extracted is selectively worn (in other words, the wear of the external teeth 27 of the first cylinder 25 is delayed).
The external teeth 27 and the internal teeth 33 are shaped in consideration of the sliding of the external teeth 27 and the internal teeth 33 due to the eccentricity of the input shaft 16 and the output shaft 19. For example, the external tooth 27 has a peak portion, that is, a top portion formed in an arc shape or the like in the tooth width direction in a sectional side view shown in FIG.

また、内歯３３は、外歯２７が摺動しながら接触箇所が歯幅方向に移動することができるように摺動分（移動代）を考慮した幅とされている。この実施の形態においては、内歯３３は、外歯２７より幅広に形成されている。詳しくは、内歯３３の歯幅Ｌ４，Ｌ４’は、外歯２７の歯幅Ｌ５,Ｌ５’よりも大きく設定されている。
第１分割体２０の第２筒体２６は、第１分割体２０の第１筒体２５に遊嵌されていて、当該第２筒体２６の内歯３３と第１筒体２５の外歯２７とが噛合している。第２分割体２１の第２筒体２６は、第２分割体２１の第１筒体２５に遊嵌されていて、当該第２筒体２６の内歯３３と第１筒体２５の外歯２７とが噛合している。 Further, the inner teeth 33 have a width in consideration of a sliding portion (movement allowance) so that the contact portion can move in the tooth width direction while the outer teeth 27 slide. In this embodiment, the inner teeth 33 are formed wider than the outer teeth 27. Specifically, the tooth widths L4 and L4 ′ of the inner teeth 33 are set larger than the tooth widths L5 and L5 ′ of the outer teeth 27.
The second cylinder 26 of the first divided body 20 is loosely fitted to the first cylinder 25 of the first divided body 20, and the inner teeth 33 of the second cylinder 26 and the outer teeth of the first cylinder 25. 27 is engaged. The second cylinder 26 of the second divided body 21 is loosely fitted to the first cylinder 25 of the second divided body 21, and the inner teeth 33 of the second cylinder 26 and the outer teeth of the first cylinder 25. 27 is engaged.

第１筒体２５の外歯２７と第２筒体２６の内歯３３とが噛合している状態では、第１筒体２５の外周面と第２筒体２６の内周面との間に第１隙間３４が形成されており、第１筒体２５及び第２筒体２６の基端側の第１隙間３４は潤滑油３５が流入する流入口３６とされている。後述するオイルケース３７内の潤滑油３５は流入口３６を通過して内歯３３や外歯２７に流れるようになっている。
連結体２２は、第１分割体２０と第２分割体２１とを連結するもので、第１分割体２０と第２分割体２１との間に配置されている。この連結体２２は第２筒体２６の外径よりも小さな円柱状の小径部３８ａと、この小径部３８ａの左右方向両端部から径外方向に突出するフランジ部３８ｂとで構成されている。 In a state where the external teeth 27 of the first cylindrical body 25 and the internal teeth 33 of the second cylindrical body 26 are engaged, the gap between the outer peripheral surface of the first cylindrical body 25 and the inner peripheral surface of the second cylindrical body 26 is between. A first gap 34 is formed, and the first gap 34 on the base end side of the first cylinder 25 and the second cylinder 26 is an inlet 36 into which the lubricating oil 35 flows. Lubricating oil 35 in an oil case 37 which will be described later passes through the inlet 36 and flows to the inner teeth 33 and the outer teeth 27.
The connecting body 22 connects the first divided body 20 and the second divided body 21, and is disposed between the first divided body 20 and the second divided body 21. The connecting body 22 includes a cylindrical small-diameter portion 38a that is smaller than the outer diameter of the second cylindrical body 26, and a flange portion 38b that protrudes radially outward from both left and right ends of the small-diameter portion 38a.

また、連結体２２は、左右方向両端面の中央部に突端が球面状をなし、プレート３０又はプレート３２に当接したときに第１筒体２５と当該ギアカップリング部５との軸方向の相対移動を規制するスラストピン２２ａを有している。
図５に示すように、入力軸１６及び出力軸１９の両端面間に形成された間隙部分の長さ（距離）をＬ０としたとき、第１筒体２５の軸方向の長さＬ１，Ｌ１’及び第２筒体２６の軸方向の長さＬ２,Ｌ２’及び連結体２２の軸方向の長さＬ３（スラストピン２２ａを含む）は、両端面間の距離Ｌ０よりも短く設定されている。即ち、Ｌ０＞Ｌ１，Ｌ１’、Ｌ０＞Ｌ２，Ｌ２’となっている。この実施の形態では、入力軸１６と出力軸１９との各端面間の距離よりも第１筒体２５の軸方向の長さＬ１，Ｌ１’，第２筒体２６の軸方向の長さＬ２,Ｌ２’及び連結体２２の軸方向の長さＬ３は小さくなっているが、プレート３０とプレート３２との距離（プレート間距離）よりも、第１筒体２５の軸方向の長さＬ１，Ｌ１’，第２筒体２６の軸方向の長さＬ２,Ｌ２’及び連結体２２の軸方向の長さＬ３は小さくするようにしてもよい。 Further, the connecting body 22 has a spherical tip at the center of both end faces in the left-right direction, and the axial direction between the first cylinder 25 and the gear coupling part 5 when contacting the plate 30 or the plate 32. A thrust pin 22a for restricting relative movement is provided.
As shown in FIG. 5, when the length (distance) of the gap formed between the both end faces of the input shaft 16 and the output shaft 19 is L0, the axial lengths L1, L1 of the first cylinder 25 are shown. 'And the axial lengths L2 and L2' of the second cylindrical body 26 and the axial length L3 (including the thrust pin 22a) of the coupling body 22 are set to be shorter than the distance L0 between both end faces. . That is, L0> L1, L1 ′, L0> L2, L2 ′. In this embodiment, the axial lengths L1, L1 ′ of the first cylindrical body 25 and the axial length L2 of the second cylindrical body 26 are larger than the distance between the end faces of the input shaft 16 and the output shaft 19. , L2 ′ and the axial length L3 of the connecting body 22 are smaller than the distance between the plates 30 and 32 (the distance between the plates). L1 ′, the axial lengths L2 and L2 ′ of the second cylindrical body 26, and the axial length L3 of the coupling body 22 may be reduced.

密閉式混練装置１の入力軸１６と駆動装置２の出力軸１９とを連結するには、まず、入力軸１６及び出力軸１９の両端面間に形成された間隙部分から入力軸１６及び出力軸１９に、前記間隙部分の距離Ｌ０より長さＬ１，Ｌ１’が短く設定された第１筒体２５を嵌め込み、この第１筒体２５に、間隙部分の距離Ｌ０より長さＬ２，Ｌ２’が短く設定された第２筒体２６を嵌め込んでそれぞれ外歯２７と内歯３３とを噛合する。
そして、第１分割体２０と第２分割体２１との間に、入力軸１６及び出力軸１９の両端面間より短い長さＬ３に設定された連結体２２（スラストピン２２ａを含む）の小径部３８ａ（連結体２２）を配置してフランジ部３８ｂを第２筒体２６の先端側に当接し、フランジ部３８ｂと第２筒体２６とをボルト等の締結具３１により締結する。 In order to connect the input shaft 16 of the closed kneading apparatus 1 and the output shaft 19 of the driving device 2, first, the input shaft 16 and the output shaft are formed from the gap portions formed between both end surfaces of the input shaft 16 and the output shaft 19. 19, a first cylinder 25 having a length L1, L1 ′ set to be shorter than the distance L0 of the gap portion is fitted, and the length L2, L2 ′ is set to the first cylinder 25 from a distance L0 of the gap portion. The second cylindrical body 26 set to be short is fitted and the external teeth 27 and the internal teeth 33 are engaged with each other.
And between the 1st division body 20 and the 2nd division body 21, the small diameter of the connection body 22 (thrust pin 22a is included) set to length L3 shorter than between the both end surfaces of the input shaft 16 and the output shaft 19. The portion 38a (connecting body 22) is arranged, the flange portion 38b is brought into contact with the distal end side of the second cylindrical body 26, and the flange portion 38b and the second cylindrical body 26 are fastened by a fastener 31 such as a bolt.

このようにすることで、入力軸１６と出力軸１９とを連結することができる。また、連結の際に、密閉式混練装置１と駆動装置２とを定置されている状態から移動する必要がなく、入力軸１６や出力軸１９に連結する前に予めカップリング部５を装着しておく必要もない。
図４に示すように、入力軸１６と出力軸１９とを接続する際、入力軸１６の軸芯と出力軸１９の軸芯とが平面視で偏心している場合であっても、ギアカップリング部５によって入力軸１６と出力軸１９とを接続することができる。 By doing in this way, the input shaft 16 and the output shaft 19 can be connected. Further, it is not necessary to move the closed kneading device 1 and the drive device 2 from the fixed state when connecting, and the coupling portion 5 is mounted in advance before connecting to the input shaft 16 or the output shaft 19. There is no need to keep it.
As shown in FIG. 4, when the input shaft 16 and the output shaft 19 are connected, even if the axis of the input shaft 16 and the axis of the output shaft 19 are eccentric in plan view, the gear coupling The input shaft 16 and the output shaft 19 can be connected by the unit 5.

第１分割体２０と第２分割体２１とを接続している状態では、第２筒体２６とプレート３０及びプレート３２との間に、第１筒体２５と第２筒体２６との間に形成された第１隙間３４に連通する第２隙間４８が形成されている。
一方で、入力軸１６と出力軸１９とをカップリング部５で接続した後に、第２筒体２６を取り外す場合には、まず、連結体２２の締結具３１を緩めて第２筒体２６から連結体２２を取り外す。このとき、内歯３３が外歯２７に対して歯幅方向にスライド可能であるので、第２筒体２６を軸方向にスライドさせることにより、連結体２２を取り外し易い構成となっている。 In a state where the first divided body 20 and the second divided body 21 are connected, between the second cylindrical body 26 and the plate 30 and the plate 32, between the first cylindrical body 25 and the second cylindrical body 26. A second gap 48 that communicates with the first gap 34 is formed.
On the other hand, when the second cylinder 26 is removed after the input shaft 16 and the output shaft 19 are connected by the coupling portion 5, first, the fastener 31 of the coupling body 22 is loosened from the second cylinder 26. The coupling body 22 is removed. At this time, since the inner teeth 33 can slide in the tooth width direction with respect to the outer teeth 27, the connecting body 22 can be easily removed by sliding the second cylindrical body 26 in the axial direction.

連結体２２を取り外した後、一方（例えば、第１分割体２０側）の第２筒体２６を出力軸１９から離れる方向に移動することで、第１筒体２５から第２筒体２６を取り外す。また、締結具３２ａ及びプレート３２を取り外し、他方（例えば、第２分割体２１側）の第２筒体２６を入力軸１６から離れる方向に移動することで、第１筒体２５から第２筒体２６を取り外す。
このとき、第２筒体２６の軸方向の長さＬ２，Ｌ２’が両端面間の距離Ｌ０よりも短く設定されているので、両端面間から第１分割体２０及び第２分割体２１の第２筒体２６をそれぞれ外部へ取り外すことができる。 After removing the connecting body 22, the second cylindrical body 26 is moved from the first cylindrical body 25 to the second cylindrical body 26 by moving one (for example, the first divided body 20 side) second cylindrical body 26 in a direction away from the output shaft 19. Remove. Further, the fastener 32 a and the plate 32 are removed, and the second cylinder 26 on the other side (for example, the second divided body 21 side) is moved in a direction away from the input shaft 16, whereby the second cylinder is moved from the first cylinder 25. Remove the body 26.
At this time, since the lengths L2 and L2 ′ in the axial direction of the second cylindrical body 26 are set to be shorter than the distance L0 between the both end faces, the first divided body 20 and the second divided body 21 are located between the both end faces. The second cylinders 26 can be removed to the outside.

第１筒体２５を取り外す場合には、第２筒体２６を取り外した後、一方の第１筒体２５を出力軸１９から離れる方向に移動することで、出力軸１９から第１筒体２５を取り外す。
また、同様に、他方の第１筒体２５を入力軸１６から離れる方向に移動することで、入力軸１６から第１筒体２５を取り外す。
このとき、第１筒体２５の軸方向の長さＬ１,Ｌ１’が両端面間の距離Ｌ０よりも短く設定されているので、両端面間から第１分割体２０及び第２分割体２１の第１筒体２５をそれぞれ外部へ取り外すことができる。 When removing the first cylinder 25, after removing the second cylinder 26, one of the first cylinders 25 is moved away from the output shaft 19, so that the first cylinder 25 is removed from the output shaft 19. Remove.
Similarly, the first cylinder 25 is removed from the input shaft 16 by moving the other first cylinder 25 in a direction away from the input shaft 16.
At this time, since the lengths L1 and L1 ′ in the axial direction of the first cylindrical body 25 are set to be shorter than the distance L0 between the both end faces, the first divided body 20 and the second divided body 21 are formed between both the end faces. The first cylinders 25 can be removed to the outside.

以上、この接続装置によれば、第２筒体２６及び連結体２２それぞれの軸方向長さＬ２，Ｌ２’，Ｌ３,が、両端面間の距離Ｌ０よりも短く設定されているので、密閉式混練装置１又は駆動装置２を定置されている状態から動かさなくても、第２筒体２６及び連結体２２を抜き取ることができる。
また、第１筒体２５の軸方向長さＬ１，Ｌ１’が、両端面間の距離Ｌ０よりも短く設定されているので、密閉式混練装置１又は駆動装置２を定置されている状態から動かさなくても、第１筒体２５を抜き取ることができる。 As described above, according to this connection device, the axial lengths L2, L2 ′, L3 of the second cylindrical body 26 and the coupling body 22 are set to be shorter than the distance L0 between both end faces. Even if the kneading device 1 or the driving device 2 is not moved from the stationary state, the second cylindrical body 26 and the connecting body 22 can be extracted.
Further, since the axial lengths L1 and L1 ′ of the first cylindrical body 25 are set to be shorter than the distance L0 between both end faces, the closed kneading device 1 or the driving device 2 is moved from the stationary state. Even if it does not exist, the 1st cylinder 25 can be extracted.

さて、潤滑部４６は、ギアカップリング部５のギア２４、即ち、第１筒体２５の外歯２７や第２筒体２６の内歯３３に対して潤滑するもので潤滑油３５を貯留するオイルケース３７を有している。

As shown in FIGS. 5 and 6, when the oil case 37 stores the lubricating oil 35 in the oil case 37, the gear 24 of the gear coupling portion 5 located above the oil case 37 is lubricated. It is for immersing in 35. The side wall 40 of the oil case 37 is raised from the bottom 41 to a height sufficient to allow the gear 24 of the gear coupling portion 5 to be immersed in the lubricating oil 35.

具体的には、オイルケース３７の前後の側壁４０（以降、前後側壁４０Ａ，４０Ｂということがある）の上縁部及び左右の側壁４０（以降、左右側壁４０Ｃ,４０Ｄということがある）の上縁部は、少なくとも断面視で底部４１に最も近い第１筒体２５の外周部よりも高い位置に設定されている。
オイルケース３７の左右側壁４０Ｃ,４０Ｄには、入力軸１６及び出力軸１９を通すための円弧状の切り欠き部４３が設けられている。入力軸１６や出力軸１６を接続する際に、入力軸１６又は出力軸１９がオイルケース３７に干渉しないように、切り欠き部４３は、入力軸１６又は出力軸１９の外径よりも大きく形成されている。 Specifically, the upper edge of the front and rear side walls 40 (hereinafter may be referred to as front and rear side walls 40A and 40B) and the left and right side walls 40 (hereinafter also referred to as left and right side walls 40C and 40D) of the oil case 37. The edge portion is set at a position higher than the outer peripheral portion of the first cylinder 25 closest to the bottom portion 41 in at least a sectional view.
The left and right side walls 40 </ b> C and 40 </ b> D of the oil case 37 are provided with arc-shaped cutout portions 43 through which the input shaft 16 and the output shaft 19 are passed. The notch 43 is formed to be larger than the outer diameter of the input shaft 16 or the output shaft 19 so that the input shaft 16 or the output shaft 19 does not interfere with the oil case 37 when the input shaft 16 or the output shaft 16 is connected. Has been.

オイルケース３７の上側には、カバー体４４が開閉自在に取り付けられている。詳しくは、オイルケース３７の後側壁４０Ｂにカバー体４４の一端がヒンジ４５を介して枢支され、カバー体４４を閉じた状態ではオイルケース３７の前側壁４０Ａにカバー体４４の他端が当接している。
カバー体４４は、板状の部材を円弧状すると共に、左右に入力軸１６又は出力軸１９が干渉しないように円弧状の切り欠き部を有する側壁を設けることで構成されており、このカバー体４４とオイルケース３７の側壁４０によって、ギアカップリング部５の外周側、即ち、第２筒体２６の外周を覆っている。 A cover body 44 is attached to the upper side of the oil case 37 so as to be freely opened and closed. Specifically, one end of the cover body 44 is pivotally supported on the rear side wall 40B of the oil case 37 via a hinge 45, and the other end of the cover body 44 is in contact with the front side wall 40A of the oil case 37 in a state where the cover body 44 is closed.

The cover body 44 is configured by forming a plate-shaped member in an arc shape and providing side walls having arc-shaped cutout portions so that the input shaft 16 or the output shaft 19 do not interfere with the left and right sides. 44 and the side wall 40 of the oil case 37 cover the outer peripheral side of the gear coupling portion 5, that is, the outer periphery of the second cylindrical body 26.

前記潤滑部４６は、オイルケース３７に貯留された潤滑油３５のレベルを検出するレベル検出手段５１と、このレベル検出手段５１で検出された潤滑油３５のレベルに基づき警報を出す警報手段５２とを有している。
レベル検出手段５１は静電式又は磁力式の液面センサなど液面レベル（油面レベル）を検出するセンサで構成されている。このセンサ５１は、例えば、オイルケース３７の後側壁４０Ｂに２つ設けられている。上側センサ５１Ａは、オイルケース３７内の潤滑油３５の油面レベルの上限（以降、上限レベルということがある）を検出する。下側センサ５１Ｂは、潤滑油の油面レベルの下限（以降、下限レベルということがある）を検出する。 The lubrication unit 46 includes a level detection unit 51 that detects the level of the lubricating oil 35 stored in the oil case 37, and an alarm unit 52 that issues an alarm based on the level of the lubricating oil 35 detected by the level detection unit 51. have.
The level detection means 51 includes a sensor for detecting a liquid level (oil level) such as an electrostatic or magnetic liquid level sensor. For example, two sensors 51 are provided on the rear side wall 40 </ b> B of the oil case 37. The upper sensor 51A detects the upper limit of the oil level of the lubricating oil 35 in the oil case 37 (hereinafter sometimes referred to as the upper limit level). The lower sensor 51B detects the lower limit (hereinafter sometimes referred to as the lower limit level) of the oil level of the lubricating oil.

潤滑油３５の下限レベルＤ１は、潤滑油３５でギアカップリング部５のギア２４を浸すことができる限界の位置であって、例えば、底部４１に最も近い内歯３３の山部からオイルケース３７の底部４１までの垂直距離とされている。
潤滑油３５の上限レベルＤ２は、潤滑油３５がオイルケース３７から漏れ出ない限界のの位置であって、例えば、底部４１に最も近い切り欠き部４３からオイルケース３７の底部４１までの垂直距離とされている。
警報手段５２はブザーやランプ又はディスプレイ上での画面表示等で警報を出すように構成されている。警報手段５２は、センサ５１によって潤滑油３５の油面レベルが上限レベルＤ２に達したときや下限レベルＤ１に達したときにレベル検出手段５１の検出信号に基づいて警報を出すように構成されている。 The lower limit level D1 of the lubricating oil 35 is the limit position where the gear 24 of the gear coupling portion 5 can be immersed with the lubricating oil 35. For example, the oil case 37 extends from the peak portion of the inner teeth 33 closest to the bottom portion 41. The vertical distance to the bottom 41 of the.
The upper limit level D2 of the lubricating oil 35 is a limit position where the lubricating oil 35 does not leak from the oil case 37. For example, the vertical distance from the notch 43 closest to the bottom 41 to the bottom 41 of the oil case 37. It is said that.
The alarm means 52 is configured to output an alarm by a screen display on a buzzer, a lamp, or a display. The alarm means 52 is configured to issue an alarm based on the detection signal of the level detection means 51 when the oil level of the lubricating oil 35 reaches the upper limit level D2 or the lower limit level D1 by the sensor 51. Yes.

以上の構成によれば、潤滑油が少なくなり過ぎて潤滑油の油面レベルが、ギアカップリング部５のギア２４を浸すことができる限界になったとき、即ち、前記下限レベルと同じとなったことを、レベル検出手段５１で検出して警報手段５２で作業者に知らせることができる。
また、潤滑油が多くなり過ぎて潤滑油の油面レベルが、オイルケース３７から漏れ出ない限界の位置になったとき、即ち、前記上限レベルと同じとなったことを、レベル検出手段５１で検出して警報手段５２で作業者に知らせることができる。 According to the above configuration, when the lubricating oil becomes too small and the oil level becomes the limit at which the gear 24 of the gear coupling portion 5 can be immersed, that is, the same as the lower limit level. This can be detected by the level detection means 51 and the warning means 52 can notify the operator.
Further, the level detecting means 51 indicates that the lubricating oil amount has increased so that the oil level of the lubricating oil has reached a limit position where it does not leak from the oil case 37, that is, the same as the upper limit level. It is possible to detect and notify the operator by the alarm means 52.

したがって、ギアカップリング部５のギア２４が潤滑油によって浸されなくなったり、潤滑油がオイルケース３７から漏れ出ることを事前に防ぐことができる。
なお、レベル検出手段５１は、下側センサ５１Ｂだけとしてもよく、潤滑油の液面までの距離を液面の上方から検出するセンサであってもよい。
本発明は上記の実施の形態に限定されない。
即ち、上記の実施の形態では、オイルケース３７に潤滑油３５を入れて、ギアカップリング部５のギア２４を潤滑油３５に浸す油浴式にしているが、これに代え、ギアカップリング部５のギア２４に粘度の高いグリースを塗り、前記流入口３６にシールを設けることで、グリースが外部に出ないようにしてもよい。 Accordingly, it is possible to prevent the gear 24 of the gear coupling unit 5 from being soaked by the lubricating oil or to prevent the lubricating oil from leaking from the oil case 37 in advance.
The level detection means 51 may be the lower sensor 51B alone, or may be a sensor that detects the distance to the liquid level of the lubricating oil from above the liquid level.
The present invention is not limited to the above embodiment.
That is, in the above embodiment, the oil case 37 is filled with the lubricating oil 35 and the gear 24 of the gear coupling portion 5 is immersed in the lubricating oil 35. However, instead of this, the gear coupling portion No. 5 may be coated with grease having high viscosity and a seal is provided at the inflow port 36 so that the grease does not go out.

また、連結体２２がスラストピン（スラスト受部）２２ａを有する構成としているが、入力軸１６側（プレート３２側）や出力軸１９側（プレート３０側）にスラスト受部を設けるようにしてもよい。
ギアカップリング部５は、当該ギアカップリングと一体となって回転しながらオイルケース内に貯留する潤滑油を汲み上げると共に、ギアカップリング部のギアに対して潤滑油を案内する案内部材５０を有することが好ましい。
図６に示すように、案内部材５０は、ギアカップリング５（例えば、第２筒体２６）の端面に周方向に沿って複数設けられている。それぞれの案内部材５０は、オイルケース３７内の潤滑油を掬う（汲み上げる）ことができる形状に形成されている。また、同じ端面側に設けられている案内部材５０は、左右の軸に対応するそれぞれの形状が左右勝手反対に形成されていることが好ましい。 Further, although the connecting body 22 has a thrust pin (thrust receiving portion) 22a, the thrust receiving portion may be provided on the input shaft 16 side (plate 32 side) or the output shaft 19 side (plate 30 side).
