Description

技術分野
本発明は、お茶、紅茶あるいはその他の被秤量物を所定量ずつ連続的に切り出す被秤量物の切り出し機構及び秤量装置に関する。
背景技術
従来より、インスタントラーメンの粉末スープや乾燥食品、お茶や紅茶等はパックに袋詰めされているが、これらのパックには一定量の製品を袋詰めする必要がある。このような粉粒状物の原料の袋詰めのための切り出し装置としては、小型のバケットコンベア上にバイブレータまたはスクリューフィーダ付きの供給フィーダを数台配置したものが一般的に知られている。
この切り出し装置においては、バイブレータによる振動を加えつつ供給フィーダより原料を連続的に排出し、それを供給フィーダの下方に配置されたバケットコンベアを連続で作動させることにより、原料はシュートを介して袋詰め装置に送られる。
しかしながら、従来の切り出し装置においては、バイブレータ付きの供給フィーダの場合は、運転時間に基づいて原料を切り出すようにしていたので、例えば電圧変動によって供給フィーダの排出速度が変化したり、あるいは、ホッパー内の被秤量物のストック量の多少により、切り出される被秤量物の量が変動してしまうという問題がある。
一方、スクリュー式の供給フィーダの場合は、被秤量物が粉体の時は良いが被秤量物に粒状物が多くなると、物を押しながら排出するので排出量がばらつき正確な切り出しが困難だった。
この対策として、作業者が常時装置について切り出し量のチェックや調整をする必要があること、また万が一にでも所定量より少ないことがないように所定量の１５〜２０％を常時多めに切り出すようにセットする必要があり被秤量物である原料の相当な無駄をしている。
また、本発明者等が先に上記の問題点を解決するために使用できる粉粒状物の連続秤量切り出し装置の一例として、特開平１０−３１８８２４号公報において図６に示す構成を有する粉粒状物の連続秤量切り出し装置Ａを提示した。
この装置は、正確な切り出しは可能であるが、回転筒１個の場合１分間に１５回程度の切り出し能力しかないため、高速な秤量切り出しを実現させるためには回転筒を多数横方向に並べる必要がある。
しかし、回転筒を列方向に多数並べると装置Ａの横幅が大きくなって、従来の切り出し装置とその後処理である袋詰めの装置のラインに乗らないという不都合があった。従来のラインは広範囲に使用されており、従来のラインを活用するためには装置を改造して省スペースな装置にする必要がある。
本発明はかかる事情に鑑みてなされたもので、被秤量物である粉粒状物等を正確に秤量して切り出し、従来の袋詰めラインに適用することが可能な被秤量物の連続秤量切り出し機構及び秤量装置を提供するものである。

発明を実施するための最良の形態
続いて、添付した図面を参照しつつ、本発明を具体化した実施の形態につき説明し、本発明の理解に供する。ここに、図１は本発明の一実施の形態に係る秤量装置の側断面図、図２は同装置の正面図、図３〜図５は同装置の部分詳細図である。
図１乃至図２に示すように、本発明の一実施の形態に係る秤量装置１は全体が丈夫な鉄又はステンレス等の素材からなって、底側部に２段に配置された２箇所の排出部２を有するホッパー３と、ホッパー３の排出部２に軸受４を介して連通され、ホッパー３から流出する粉粒状物を徐々に下方に移動させる２段に配置された２個の傾斜を持った細長の回転筒５と、回転筒５を回転させる２段に配置された２個のモーター機構６と、回転筒５から切り出される粉粒状物を一時収納する２段に配置された２個の受け容器７と、受け容器７に投入された粉粒状物を、その風袋と共に秤量する２個のロードセル８と、ロードセル８からの信号を基にして、受け容器７の排出ダンパー９を開く２段に配置された２個のダンパー開閉機構１０と、受け容器７から排出される所定量の粉粒状物を下方に排出する１つのシュート１１と、これらを支持する架台１２とを有している。以下、これらについて詳しく説明する。
前記ホッパー３は、上部を架台１２に固定され、下部は徐々に細くなり底側部に２段に配置された２箇所の排出部２が形成され、一方の底側部は開閉蓋１３が設けられ、残った被秤量物を外部に排出できるようになっている。
前記ホッパー３の２箇所の排出部２には、それぞれ軸受４が設けられ、２段に配置された２個の回転筒５の一端部が回転自在に支持されている。
２個の回転筒５のそれぞれの入り口側端部には、羽根板１４を備える被秤量物導入筒１５が交換可能に取付けられていて、ホッパー３の２箇所の排出部２近傍に溜まった被秤量物を攪拌して各回転筒５に徐々に導くようになっている。
各回転筒５の中間部は中間軸受１６によって回転自在に支持されていると共に、軸受４と中間軸受１６は傾斜支持板１７によって支持されており、各回転筒５は常時一定の角度（０〜１２度の範囲）の下り勾配となっている。尚、傾斜支持板１７は、架台１２底部の固定支持部材１８ａと調整ボルト１８によって所定角度で架台１２に固定されている。
前記２個の回転筒５の中間位置にはプーリー１９が設けられ、各回転筒５はタイミングベルト２０を介して傾斜支持板１７の下部に２段に配置された２個のモーターの出力軸３６と連結されている。
各モーター２１の回転に伴い各回転筒５は回転し、各被秤量物導入筒１５内を介して各回転筒５内に流れ込んだ被秤量物は、各回転筒５の勾配と回転によって徐々に下方に流れ出して、一定の速度で各回転筒排出口２３から排出される。
前記２個の回転筒排口２３から排出される被秤量物を受ける２個の受け容器７は、底部が傾斜底板２４となった２個のバケット２５と各バケット２５の上部にピン２６を介して開閉可能となるように各バケット２５の一方に配置される２個の排出ダンパー９とを備えている。
この２個の受け容器７は、架台１２の上部に固定された２個のロードセル８から図３のようにそれぞれつり下げられており、各ロードセル８によって、各受け容器７とその内部に溜まった被秤量物の重さを測定し、電気的信号を出すようになっている。このロードセル８からの信号によって、各回転筒５の高低速切り替え及び各排出ダンパー９の開閉タイミングが制御される。
前記２個の受け容器７は、図４乃至図５に示すように、それぞれダンパー開閉機構１０が設けられて、各ロードセル８からの所定の信号によって、各排出ダンパー９を作動させて各受け容器７内に溜まった所定重量の被秤量物を下部のシュート１１に排出するようになっている。
ダンパー開閉機構１０は、排出ダンパー９の突起部２７を持ち上げるために一端を回転可能なピン２８を介して固定された作動アーム２９と、その中間部をピン３０を介して回転自在に作動アーム２９と連結した連結アーム３１と、連結アーム３１の上部に回転可能にピン３２を介して連結された回転アーム３３と、回転アーム３３を３６０度回転させるモーター３４と、回転アーム３３の原位置、即ち排出ダンパー９の開の位置を検知する近接センサー３５と、モーター３４の支持部材３６とを有している。
前記ロードセル８から所定の信号があった場合には、モーター３４が回転して回転アーム３３が図４の矢印のように回転し、連結アーム３１が持ち上がり、作動アーム２９は点Ｂを支点として点Ｃが上昇し、排出ダンパー９の突起部２７を持ち上げ、その結果排出ダンパー９が開く。
これによって、指定された受け容器７内に溜まった被秤量物は下方のシュート１１に排出されるが、回転アーム３３が一回転すると作動アーム２９が元の位置に戻って排出ダンパー９は閉じる。
ここで、回転アーム３３の動作を確実に行うために回転アーム３３が３６０度回転して、再度原点位置にあることを検出する近接センサー３５が設けられている。
被秤量物を排出するシュート１１は断面が角形となって、下方に縮幅し２個の受け容器７から排出された被秤量物を確実に下部のシュート排出口３７から排出するようになっている。
以上の構成となっているので、粉粒状物の被秤量物はホッパー３の底側部の２箇所の排出部２から２個の被秤量物導入筒１５を経て２個の回転筒５を通って２個の受け容器７に流れ込む。
ここで、各回転筒５はロードセル８の測重信号が目標値の９０％までは１００〜１５０ｒｐｍの高速で回転し、測重信号が目標値の９０％になった時点で１０〜１５ｒｐｍの速度の低速回転に変わり、各回転筒５から徐々に受け容器７に被秤量物を排出して正確な秤量を行うようになっている。
そして、本構成では、後処理である袋詰めラインのサイクルタイムに間に合うように、秤量が完了した受け容器７の排出ダンパー９の開閉を制御するようになっている。
指定された受け容器７から排出された被秤量物は、１つのシュート１１を通って袋詰めラインへ送られる。
本実施の形態では、回転筒５を上下方向に２段にしたものについて説明したが、必ずしも２段に限定されるものではない。即ち、上下方向に回転筒５を複数段設けるようにすれば、従来のラインをそのまま利用でき、しかもより高速に秤量切り出しを実現できるからである。また、ホッパー３に設けた排出部２についても同様に上下方向に２段にしたものに限られることなく、複数段の排出部２を設けるようにすればより効率的に回転筒５へ被秤量物を送り出すことができるようになる。
そして、これら複数段設けられた各回転筒５をホッパ３ーに設けられた複数個の排出部２にそれぞれ連通するようにしてもよい。さらに、排出部２を上下方向だけでなく左右方向に複数列設け、それぞれに回転筒５を連通すればさらなる高速化を図ることができる。例えば、２段２個の回転筒を１つのユニットとすると、１ユニットあたり３０回／分の秤量切り出し能力を持つので、このユニットを１０個並べると合計３０回／分の能力を持つ高速秤量切り出し装置を構成することができる。
また、被秤量物が粉粒状物のときには、供給フィーダ等から送り出される粉粒状物の量のばらつき等に影響されることなく正確な切り出しが可能となる。
産業上の利用可能性
秤量機構は、以上の説明からも明らかなように、複数段分並べることによりより高速かつ正確な秤量を可能にし、高速な秤量装置を構成することができる。
これにより、従来からの問題であった常時１５乃至２０％の原料を多く投入している点、及び常時作業者が監視しなければならないという点が改善されて、大きな合理化につながる。

As shown in FIGS. 1 and 2, the weighing device 1 according to an embodiment of the present invention is made of a material such as a strong iron or stainless steel as a whole, and is arranged at two locations arranged in two stages on the bottom side. A hopper 3 having a discharge part 2 and two inclinations arranged in two stages that are communicated with the discharge part 2 of the hopper 3 through a bearing 4 and gradually move the powder particles flowing out of the hopper 3 downward. A long and narrow rotating cylinder 5, two motor mechanisms 6 arranged in two stages for rotating the rotating cylinder 5, and two arranged in two stages for temporarily storing the powder and particulate matter cut out from the rotating cylinder 5 Receiving container 7, two load cells 8 for weighing together with the tare of the granular material charged in receiving container 7, and opening discharge damper 9 of receiving container 7 based on a signal from load cell 8 2 Two damper opening / closing mechanisms 10 arranged in a step, and a receiving container It has a single chute 11 for discharging a predetermined amount of particulate matter downwardly discharged, and a frame 12 for supporting them from. These will be described in detail below.
The upper part of the hopper 3 is fixed to the gantry 12, and the lower part is gradually thinned to form two discharge parts 2 arranged in two steps on the bottom side part, and one bottom side part is provided with an opening / closing lid 13. The remaining weighing object can be discharged to the outside.
Two discharge portions 2 of the hopper 3 are provided with bearings 4, respectively, and one end portions of two rotary cylinders 5 arranged in two stages are rotatably supported.
A weighed material introduction cylinder 15 having a blade 14 is replaceably attached to the inlet side end of each of the two rotary cylinders 5, and is covered in the vicinity of the two discharge parts 2 of the hopper 3. The weighed material is agitated and gradually guided to each rotating cylinder 5.
An intermediate portion of each rotary cylinder 5 is rotatably supported by an intermediate bearing 16, and the bearing 4 and the intermediate bearing 16 are supported by an inclined support plate 17, and each rotary cylinder 5 is always at a constant angle (0 to 0). It is a downward slope of 12 degrees). The inclined support plate 17 is fixed to the gantry 12 at a predetermined angle by a fixed support member 18 a at the bottom of the gantry 12 and an adjusting bolt 18.
A pulley 19 is provided at an intermediate position between the two rotary cylinders 5, and each rotary cylinder 5 is provided with two motor output shafts 36 arranged in two stages below the inclined support plate 17 via a timing belt 20. It is connected with.
Each rotating cylinder 5 rotates with the rotation of each motor 21, and the weighed material flowing into each rotating cylinder 5 through each weighed material introducing cylinder 15 is gradually caused by the gradient and rotation of each rotating cylinder 5. It flows downward and is discharged from each rotary cylinder discharge port 23 at a constant speed.
The two receiving containers 7 that receive the objects to be weighed discharged from the two rotary cylinder outlets 23 are provided with two buckets 25 whose bottom portions are inclined bottom plates 24 and pins 26 on the upper portions of the buckets 25. And two discharge dampers 9 arranged on one side of each bucket 25 so as to be openable and closable.
The two receiving containers 7 are suspended from the two load cells 8 fixed to the upper part of the gantry 12 as shown in FIG. 3, and are accumulated in each receiving container 7 and inside thereof by each load cell 8. The weight of the object to be weighed is measured and an electric signal is output. The signal from the load cell 8 controls the high / low speed switching of each rotary cylinder 5 and the opening / closing timing of each discharge damper 9.
As shown in FIGS. 4 to 5, each of the two receiving containers 7 is provided with a damper opening / closing mechanism 10, and each discharging damper 9 is operated in response to a predetermined signal from each load cell 8. 7 is discharged to the lower chute 11.
The damper opening / closing mechanism 10 has an operation arm 29 fixed at one end via a pin 28 that can be rotated to lift the protrusion 27 of the discharge damper 9, and an operation arm 29 that is rotatable at an intermediate portion via a pin 30. A connecting arm 31 connected to the connecting arm 31, a rotating arm 33 rotatably connected to the upper portion of the connecting arm 31 via a pin 32, a motor 34 for rotating the rotating arm 33 by 360 degrees, and an original position of the rotating arm 33, that is, A proximity sensor 35 for detecting the open position of the discharge damper 9 and a support member 36 for the motor 34 are provided.
When there is a predetermined signal from the load cell 8, the motor 34 rotates and the rotating arm 33 rotates as shown by the arrow in FIG. 4, the connecting arm 31 is lifted, and the operating arm 29 is pointed with the point B as a fulcrum. C rises and raises the protrusion 27 of the discharge damper 9, so that the discharge damper 9 opens.
As a result, the object to be weighed in the designated receiving container 7 is discharged to the lower chute 11, but when the rotating arm 33 makes one rotation, the operating arm 29 returns to the original position and the discharge damper 9 is closed.
Here, in order to reliably perform the operation of the rotary arm 33, a proximity sensor 35 that detects that the rotary arm 33 has rotated 360 degrees and is at the origin position again is provided.
The chute 11 for discharging the object to be weighed has a square cross section, and is reduced in width downward so that the object to be weighed discharged from the two receiving containers 7 is surely discharged from the lower chute discharge port 37. Yes.
With the above configuration, the weighed material of the granular material passes from the two discharge parts 2 on the bottom side of the hopper 3 through the two weighed substance introduction cylinders 15 and the two rotating cylinders 5. Into the two receiving containers 7.
Here, each rotating cylinder 5 rotates at a high speed of 100 to 150 rpm until the weight signal of the load cell 8 reaches 90% of the target value, and the speed of 10 to 15 rpm when the weight signal reaches 90% of the target value. In place of the low-speed rotation, the objects to be weighed are gradually discharged from the rotating cylinders 5 to the receiving container 7 for accurate weighing.
In this configuration, the opening / closing of the discharge damper 9 of the receiving container 7 whose weighing has been completed is controlled so as to be in time for the cycle time of the bagging line as post-processing.
The object to be weighed discharged from the designated receiving container 7 is sent to the bagging line through one chute 11.
In the present embodiment, the rotary cylinder 5 has been described as having two stages in the vertical direction, but is not necessarily limited to two stages. That is, if a plurality of rotating cylinders 5 are provided in the vertical direction, the conventional line can be used as it is, and weighing out can be realized at a higher speed. Similarly, the discharge portion 2 provided in the hopper 3 is not limited to the one having two stages in the vertical direction, and if the plurality of discharge portions 2 are provided, the weight to be measured is more efficiently measured on the rotary cylinder 5. You can send things out.
Then, the rotating cylinders 5 provided in a plurality of stages may be communicated with a plurality of discharge portions 2 provided in the hopper 3. Furthermore, if the discharge portions 2 are provided in a plurality of rows not only in the vertical direction but also in the horizontal direction, and the rotary cylinder 5 is communicated with each of the rows, the speed can be further increased. For example, if two rotating cylinders are used as one unit, it has the ability to weigh out 30 times / minute per unit, so if you put 10 units in this unit, you will be able to weigh out at a high speed with a total capacity of 30 times / minute. A device can be configured.
In addition, when the object to be weighed is a granular material, accurate cutting can be performed without being affected by variations in the amount of the granular material delivered from a supply feeder or the like.
As is apparent from the above description, the industrial applicability weighing mechanism enables a high-speed and accurate weighing by arranging a plurality of stages, and a high-speed weighing device can be configured.
As a result, the point that a large amount of the raw material of 15 to 20%, which has been a problem in the past, is constantly added and the point that the worker must always monitor is improved, leading to a great rationalization.
