Description

本発明は、押出機によって押出成形されたゴム部材をテイクアウェイコンベア（以下、単に「コンベア」ともいう）にて搬送しながら冷却するゴム部材の冷却装置に関する。   The present invention relates to a rubber member cooling apparatus that cools a rubber member extruded by an extruder while being conveyed by a takeaway conveyor (hereinafter also simply referred to as a “conveyor”).

従来、押出機によって押出成形されたゴム部材は高温であるため、押出機から押し出された直後のゴム部材をコンベアを用いて次工程に搬送するに際して、冷却水が蓄えられた水槽を備えたゴム部材の冷却装置（以下、単に「冷却装置」ともいう）を経由させることにより、冷却している（例えば、特許文献１）。   Conventionally, since the rubber member extruded by the extruder has a high temperature, when the rubber member immediately after being extruded from the extruder is transported to the next process using a conveyor, the rubber provided with a water tank in which cooling water is stored Cooling is performed by passing through a cooling device for members (hereinafter, also simply referred to as “cooling device”) (for example, Patent Document 1).

図３に、このような従来の冷却装置の一例を示す。この冷却装置５０は、図３に示すように、押出機（図示せず）から押し出された直後のゴム部材Ｍを搬送するコンベア５２が水槽５１内に配置されている。水槽５１内には、シャワー支持部材５３に設けられた複数のシャワー５４から冷却水Ｗが常に散布されて供給されている。そして、供給された冷却水Ｗが蓄えられた水槽５１内のコンベア５２上をゴム部材Ｍが搬送されることにより、ゴム部材Ｍが充分に冷却されて、次工程へ搬送される。   FIG. 3 shows an example of such a conventional cooling device. As shown in FIG. 3, in the cooling device 50, a conveyor 52 that conveys a rubber member M immediately after being extruded from an extruder (not shown) is disposed in a water tank 51. In the water tank 51, the cooling water W is always sprayed and supplied from a plurality of showers 54 provided on the shower support member 53. And the rubber member M is fully cooled by being conveyed on the conveyor 52 in the water tank 51 in which the supplied cooling water W was stored, and is conveyed to the next process.

特開平８−９０５５８号公報JP-A-8-90558

しかしながら、上記した従来の冷却装置５０の場合、コンベア５２だけでなくローラー５５などの駆動部も水槽５１内に設置されているため、駆動部に腐食や錆が生じやすく、安定した潤滑性を維持することが難しく、駆動部の寿命が短くなるという問題があった。   However, in the case of the above-described conventional cooling device 50, not only the conveyor 52 but also the driving unit such as the roller 55 are installed in the water tank 51, so that the driving unit is easily corroded and rusted and maintains a stable lubricity. There is a problem that it is difficult to do so and the life of the drive unit is shortened.

また、水槽５１内では冷却水Ｗの水位が高いため、コンベア５２の移動に合わせて下流側に移動する冷却水Ｗが波打って下流側に移動し、その後、水槽５１の壁面に衝突して、跳ね上がることにより水槽５１の壁面を越えて、周囲を水浸しにしてしまう恐れがあった。   Moreover, since the water level of the cooling water W is high in the water tank 51, the cooling water W that moves downstream as the conveyor 52 moves undulates and moves downstream, and then collides with the wall surface of the water tank 51. There was a risk that the water would jump over the wall surface of the water tank 51 and the surrounding area would be flooded.

そこで、本発明は、駆動部の寿命が長く、周囲を水浸しにしてしまう恐れがないゴム部材の冷却装置を提供することを課題とする。   Therefore, an object of the present invention is to provide a rubber member cooling device that has a long drive life and does not cause the surroundings to be immersed in water.

以下、本発明を実施の形態に基づき、図面を参照して説明する。   Hereinafter, the present invention will be described based on embodiments with reference to the drawings.

１．第１の実施の形態
図１は第１の実施の形態に係るゴム部材の冷却装置を模式的に示す側面図である。 1. First Embodiment FIG. 1 is a side view schematically showing a cooling device for a rubber member according to a first embodiment.

図１に示すように、本実施の形態に係る冷却装置１は、第１の水槽１１と、その内側に配置された第２の水槽１２とを備えている。   As shown in FIG. 1, the cooling device 1 according to the present embodiment includes a first water tank 11 and a second water tank 12 disposed inside thereof.

第１の水槽１１には、テイクアウェイコンベア１３のローラー１４や図示しないスプロケットやテイクアップ（コンベア１３のテンションを調整する機構）などの駆動部が配置されていると共に、コンベア１３のリターン側１３ｂが収納されている。   The first water tank 11 is provided with a drive unit such as a roller 14 of the takeaway conveyor 13, a sprocket (not shown) and a take-up (mechanism for adjusting the tension of the conveyor 13), and a return side 13 b of the conveyor 13. It is stored.

また、第２の水槽１２には、コンベア１３のキャリア側１３ａが収納されており、第２の水槽１２の上方に配置されたシャワー支持部材１６に設けられた複数のシャワー１５から散布された冷却水Ｗが第２の水槽１２の内部に蓄えられている。   Moreover, the carrier side 13a of the conveyor 13 is accommodated in the 2nd water tank 12, and the cooling sprayed from the several shower 15 provided in the shower support member 16 arrange | positioned above the 2nd water tank 12 is carried out. Water W is stored inside the second water tank 12.

押出機（図示せず）から押し出されたゴム部材Ｍは、第２の水槽１２内でコンベア１３のキャリア側１３ａにより下流側に向けて搬送され、第２の水槽１２内に蓄えられた冷却水Ｗを経由することにより冷却される。   The rubber member M pushed out from an extruder (not shown) is conveyed toward the downstream side by the carrier side 13a of the conveyor 13 in the second water tank 12, and is stored in the second water tank 12. It is cooled by going through W.

このように、本実施の形態に係る冷却装置１は、ローラー１４などの駆動部が第１の水槽１１内に配置されて、冷却水とは接触しないようにされているため、駆動部に腐食や錆が生じることが抑制されて、安定した潤滑性を長期間に亘って維持することができ、駆動部の寿命を長期化させることができ、メンテナンス間隔も長期化させることができる。   Thus, the cooling device 1 according to the present embodiment corrodes the driving unit because the driving unit such as the roller 14 is disposed in the first water tank 11 so as not to contact the cooling water. Occurrence of rust and rust can be suppressed, stable lubricity can be maintained over a long period of time, the life of the drive unit can be extended, and the maintenance interval can also be extended.

そして、第２の水槽１２内において、従来のように、冷却水Ｗが下流側の壁面に衝突して跳ね上がって第２の水槽１２の壁面を越えても、越えた冷却水Ｗを第１の水槽１１内に蓄えることができるため、冷却装置１の周囲を水浸しにしてしまう恐れがない。   In the second water tank 12, the cooling water W collides with the wall surface on the downstream side and jumps up and exceeds the wall surface of the second water tank 12 as in the conventional case. Since it can be stored in the water tank 11, there is no fear that the periphery of the cooling device 1 will be immersed in water.

また、前記したように、コンベア１３のリターン側１３ｂは、駆動部と共に、第１の水槽１１内に配置されているため、キャリア側１３ａからリターン側１３ｂへと移動したコンベア１３に付着した冷却水Ｗの水滴も第１の水槽１１の外へ漏れることがなく、第２の水槽１２の壁面を越えた上記の冷却水と併せて、回収、排水することができるため、この面からも、周囲を水浸しにしてしまう恐れがない。   Further, as described above, since the return side 13b of the conveyor 13 is disposed in the first water tank 11 together with the drive unit, the cooling water adhered to the conveyor 13 moved from the carrier side 13a to the return side 13b. Since water droplets of W do not leak out of the first water tank 11 and can be collected and drained together with the above cooling water beyond the wall surface of the second water tank 12, this surface also There is no risk of immersing

そして、これら第１の水槽１１内に蓄えられた冷却水Ｗは、容易に回収、排水することができるため、運転コストの低減を図ることができる。   And since the cooling water W stored in these 1st water tank 11 can be collect | recovered and drained easily, it can aim at reduction of an operating cost.

２．第２の実施の形態
図２は第２の実施の形態に係る冷却装置の構成、および機能を説明する側面図である。 2. Second Embodiment FIG. 2 is a side view for explaining the configuration and function of a cooling device according to a second embodiment.

図２（ａ）に示すように、本実施の形態に係る冷却装置１は、第２の水槽１２の側壁１７の一部１７ａの高さが調節可能に構成されている点において、第１の実施の形態に示した冷却装置と異なっている。なお、図２（ａ）では、第２の水槽１２の左側に第２の水槽１２の外部を、右側に第２の水槽１２の内部を示している。   As shown to Fig.2 (a), the cooling device 1 which concerns on this Embodiment is 1st in the point that the height of the part 17a of the side wall 17 of the 2nd water tank 12 is adjustable. It is different from the cooling device shown in the embodiment. In FIG. 2A, the outside of the second water tank 12 is shown on the left side of the second water tank 12, and the inside of the second water tank 12 is shown on the right side.

第２の水槽１２の側壁１７の一部１７ａを上下させるなどして、第２の水槽１２における高さを調節することにより、側壁１７の一部１７ａの高さを超える水位の冷却水Ｗを排出して、第２の水槽１２における冷却水Ｗの水位Ｐを容易に調整することができる。   By adjusting the height of the second water tank 12 by moving the part 17a of the side wall 17 of the second water tank 12 up and down, the cooling water W having a water level exceeding the height of the part 17a of the side wall 17 is supplied. By discharging, the water level P of the cooling water W in the second water tank 12 can be easily adjusted.

例えば、図２（ｂ）に示すように、第２の水槽１２の側壁１７の一部１７ａを上げた場合には、冷却水Ｗの水位Ｐを第２の水槽１２の上面近くの高さに設定することができ、一方、図２（ｃ）に示すように、第２の水槽１２の側壁１７の一部１７ａを下げた場合には、冷却水Ｗの水位Ｐを低く設定することができる。   For example, as shown in FIG. 2B, when a part 17 a of the side wall 17 of the second water tank 12 is raised, the water level P of the cooling water W is set to a height near the upper surface of the second water tank 12. On the other hand, as shown in FIG. 2C, when the portion 17a of the side wall 17 of the second water tank 12 is lowered, the water level P of the cooling water W can be set low. .

このように、本実施の形態によれば、ゴム部材Ｍが適切に浸るように第２の水槽１２中の冷却水Ｗの水位を適宜調整することができるため、キャリア側１３ａを搬送されるゴム部材Ｍにより発生する冷却水Ｗの波打ちを抑制して、冷却水Ｗの跳ね上がりによって冷却装置１の周囲が水浸しになることを防止することができる。   As described above, according to the present embodiment, since the water level of the cooling water W in the second water tank 12 can be adjusted as appropriate so that the rubber member M is appropriately immersed, the rubber conveyed on the carrier side 13a. The undulation of the cooling water W generated by the member M can be suppressed, and the surroundings of the cooling device 1 can be prevented from being flooded by the splashing of the cooling water W.

また、ゴム部材Ｍに合わせて適切な水位Ｐに容易に調整することが可能となるため、１台の冷却装置で種々の厚みのゴム部材に対応することができ、冷却装置のより効率的な運用を図ることができる。   In addition, since it is possible to easily adjust the water level P to an appropriate level according to the rubber member M, it is possible to cope with rubber members having various thicknesses with a single cooling device. Operation can be planned.

本発明者が、図２に示した冷却装置を用いてゴム部材の冷却を行ったところ、従来の冷却装置では、状況によって短期間で駆動部に腐食や錆が生じて交換せざるを得なかったのに対し、稼働開始後１カ年を経過しても駆動部に腐食や錆が生じることがなく、駆動部を構成する各部品の寿命が大幅に長期化され、メンテナンス回数も大幅に低減された。また、冷却水の飛び跳ねによる水槽周りが水浸しになる回数も、従来に比べて大きく低減させることができた。   When the present inventor cooled the rubber member using the cooling device shown in FIG. 2, the conventional cooling device has to be replaced due to corrosion or rust in the drive part in a short period of time depending on the situation. On the other hand, even if one year has passed since the start of operation, the drive unit will not be corroded or rusted, the life of each component of the drive unit will be greatly prolonged, and the number of maintenance will be greatly reduced. It was. In addition, the number of times that the periphery of the water tank is flooded due to jumping of the cooling water can be greatly reduced as compared with the conventional case.

以上、本発明を実施の形態に基づいて説明したが、本発明は、上記の実施の形態に限定されるものではない。本発明と同一および均等の範囲内において、上記の実施の形態に対して種々の変更を加えることが可能である。   While the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments. Various modifications can be made to the above-described embodiment within the same and equivalent scope as the present invention.
