Description

本発明は製茶揉捻機に関するものであり、詳しくは製茶揉捻機の揉盤のうち、中心の茶葉取出部の構造に関するものである。 The present invention relates to a tea making machine and, more particularly, to the structure of a central tea leaf take-out part of a board of the tea making machine.

製茶揉捻機は、茶葉をまとめて揉圧しながら混合し、粗揉の揉み不足をおぎなうと同時に茶葉の水分をならす機械であり、茶葉をのせる揉盤、茶葉を入れて回転する揉捻鉢、それを加圧する揉圧盤などで構成している。さらに揉盤には、揉みの効率を向上させるために、ヒルと呼ばれる複数本の弧状凸状の金属棒が備えられている。 The tea making machine is a machine that mixes tea leaves together under pressure, removes the kneading of the coarse koji, and at the same time smooths the water of the tea leaves. It is composed of a rolling platen that pressurizes Further, the grid is provided with a plurality of arc-shaped metal bars called hills in order to improve the efficiency of stagnation.

揉みの効率を考慮するとヒルは多いことが望まれる一方、常に強い揉捻作用がかかることで茶葉に細かく粉砕されてしまい、茶葉の性状としては好ましくない場合もある。また、ヒルによって茶葉がうまく転がらず水分が均一にならないこともある。 Considering the efficiency of kneading, it is desirable that there are many leeches, but since a strong twisting action is always applied, the tea leaves are finely pulverized, which is not preferable as the properties of the tea leaves. In addition, tea leaves do not roll well due to leeches, and moisture may not be uniform.

従来、揉盤の中心にある茶葉取出部はヒルが備えられた鋳物で製造されている。特許文献１ではこれら背景をもとに揉盤ヒル（本明細書ではヒル）の本数、揉圧錘（本明細書では揉圧盤）双方の改善を進めている。これは、摘採時期、場所、日時によって茶葉の状態は異なるためヒルの数を状況に応じて変更するものであり、ヒルが揉盤に対してネジにより付替え自在になっているものである。 Conventionally, the tea leaf takeout part at the center of the grid is manufactured by a casting provided with a hill. In Patent Document 1, based on these backgrounds, improvements are being made to both the number of spar board hills (in this specification, hills) and the squeezing weights (in this specification, squeezing plates). This is because the state of the tea leaves varies depending on the picking time, place, date and time, and the number of hills is changed according to the situation, and the hills can be freely attached to the board with screws.

特開２００８−９２８４３号公報JP 2008-92843 A

従来、ヒルの本数を変えるには茶葉取出部の鋳物の交換となり、交換には時間を要したり、面倒だったりして交換をしないままになっていた。しかし、茶葉の性状に応じて、ヒルの本数を変更する方が、茶葉の製品の品質は向上する。 Conventionally, changing the number of hills requires replacement of the casting at the tea leaf extraction part, which takes time or is cumbersome and does not require replacement. However, the quality of the tea leaf product is improved by changing the number of leeches according to the properties of the tea leaf.

特許文献１の場合は、ヒルを揉盤に対してネジで付け替えるものであり、揉盤上に多数のネジ孔を開口して、そこに閉塞プラグをねじ込む。ネジ孔に閉塞プラグをねじ込むと、ネジ孔から閉塞プラグが外れて加工中の茶葉に混入する恐れがあり、更にネジ孔に加工中の茶葉が入り込む可能性がある。また、どこか１箇所のヒルをつけたり外したりするのではなく、ヒルをバランスよく増減することが必要である。 In the case of Patent Document 1, the hill is replaced with a screw with respect to the board, and a number of screw holes are opened on the board and a closing plug is screwed therein. If the plug is screwed into the screw hole, the plug may be removed from the screw hole and mixed into the tea leaf being processed, and the tea leaf being processed may enter the screw hole. In addition, it is necessary to increase or decrease the hills in a balanced manner, instead of attaching or removing one hill somewhere.

本発明は、揉盤のヒルの本数を状況に応じて容易に変更できるようにするものである。 The present invention makes it possible to easily change the number of hills on the board depending on the situation.

請求項１記載の製茶揉捻機は、複数のヒルを備えた揉盤と、揉盤上を回転する揉捻鉢と、揉捻鉢内の茶葉に加圧するための揉圧盤とよりなる製茶揉捻機において、揉盤の中心部に設けた開閉自在な茶葉取出部を、茶葉に接する取出揉盤と開閉機構を有する取出扉に分割し、取出揉盤と取出扉を着脱自在にするものである。 The tea making machine according to claim 1 is a tea making machine comprising a board with a plurality of hills, a rice bowl that rotates on the board, and a rice bowl that presses the tea leaves in the bowl. An openable and closable tea leaf take-out section provided at the center of the slat is divided into a take-out slat and a take-out door having an opening and closing mechanism that are in contact with the tea leaves, so that the take-out slab and the take-out door are detachable.

請求項２記載の製茶揉捻機は、請求項１において、ヒルの本数が異なる取出揉盤を複数用意し、取出扉に付替え自在とするものである。 According to a second aspect of the present invention, there is provided a tea making and twisting machine according to the first aspect, wherein a plurality of take-out grinders having different numbers of hills are prepared, and the take-out door can be replaced with a take-out door.

請求項１では、茶葉取出部の取出揉盤と取出扉が着脱自在なので、必要に応じて取出揉盤を交換することが可能である。茶葉の茶渋が取出揉盤にべったりついた場合、取出揉盤だけ取り外して洗浄したり、新品に付け替えたりすることができる。 In claim 1, since the takeout board and the takeout door of the tea leaf takeout part are detachable, it is possible to replace the takeout board as necessary. If the tea leaves of tea leaves stick to the takeout board, it can be removed and washed, or replaced with a new one.

請求項２では、ヒルの本数を変更したい場合に、揉盤の取出部の取出揉盤のみの交換となり、交換作業が容易で、交換部品も軽量で、交換に要する時間も短縮される。揉盤全体のヒルの本数を変更しなくても、取出揉盤のヒルの本数を変更するだけで、茶葉の揉み込み不足の解消、または、粉茶の発生の解消に効果的である。 In claim 2, when it is desired to change the number of hills, only the take-out board of the take-out part of the board is replaced, the replacement work is easy, the replacement parts are lightweight, and the time required for replacement is shortened. Even if the number of hills in the entire board is not changed, the change in the number of hills in the take-out board is effective in eliminating the shortage of tea leaves or the occurrence of powdered tea.

図１〜４を参照して、製茶揉捻機について説明する。１は製茶揉捻機であり、主に揉盤２、揉捻鉢３、揉圧盤４で構成されている。揉捻鉢３は３箇所のクランク式のクランクアーム５により支持しており、モータ（図示しない）によってクランクアーム５を駆動することにより、揉捻鉢３は揉盤２上を回転運動する。クランクアーム５が駆動して危険なため、アームカバー６を備えている。揉捻鉢３の裾には掃き込みブラシ７を設けている。揉圧盤４の上には分銅８、分銅レール９があり、分銅８はモータの動力又は手動ハンドル（図示しない）を手動で動かすことにより、分銅レール９上を前後に移動する。分銅８を前へ移動すると茶葉への加圧が強くなり、後ろへ移動すると茶葉への加圧が弱くなる。１０は揉盤２上へ設けたヒルであり、茶葉を中央へ集めたり、揉捻効果を高めたりするものである。１１は揉盤２の中央へ設けた茶葉取出部であり、取出時には茶葉取出部１１が下方へ開き、茶葉を下のコンベヤ２２へ落下させる。コンベヤ２２はこの落下した茶葉を次の装置へ搬送する。２１はシュートであり、バケットコンベヤ（図示しない）などから落下する茶葉を揉捻鉢３へ導く。 The tea making machine will be described with reference to FIGS. Reference numeral 1 denotes a tea making machine, which mainly includes a board 2, a bowl 3, and a platen 4. The pestle bowl 3 is supported by three crank-type crank arms 5, and the pestle bowl 3 rotates on the board 2 by driving the crank arm 5 by a motor (not shown). Since the crank arm 5 is dangerous to drive, an arm cover 6 is provided. A sweeping brush 7 is provided at the hem of the bowl 3. There are a weight 8 and a weight rail 9 on the pressure platen 4, and the weight 8 moves back and forth on the weight rail 9 by manually moving the power of the motor or a manual handle (not shown). When the weight 8 is moved forward, the pressure on the tea leaves is increased, and when the weight 8 is moved rearward, the pressure on the tea leaves is weakened. Reference numeral 10 denotes a hill provided on the grid 2, which collects tea leaves in the center and enhances the twisting effect. Reference numeral 11 denotes a tea leaf take-out section provided at the center of the grid 2. The tea leaf take-out section 11 opens downward at the time of take-out, and drops the tea leaves onto the lower conveyor 22. The conveyor 22 conveys the dropped tea leaves to the next device. Reference numeral 21 denotes a chute that guides tea leaves falling from a bucket conveyor (not shown) or the like to the bowl 3.

次に、上記のような製茶揉捻機１の動作を説明する。シュート２１により茶葉を揉盤２上の揉捻鉢３の中へ投入する。このとき、分銅８は分銅レール９の一番後ろに位置しており、揉圧盤４に圧力がかからないようにしている。揉圧盤４は円錐形をしており、加圧がされていないため、投入された茶葉は、揉捻鉢３の中、かつ揉圧盤４の下に入る。揉捻鉢３、揉圧盤４などは揉盤２上を水平運動しており、茶葉は回転移動しながら加圧により揉み込まれる。茶葉の様子を見ながら、分銅８を移動して加圧力を変え、茶葉の内部の水分が表面ににじみ出て、茶葉全体の水分が均一になるように揉み込む。この分銅８の移動は人が行なってもよいが、分銅８の位置と時間を設定しておいて制御すると便利である。茶葉が揉盤２上を移動するとき、揉圧盤４により加圧されるにもかかわらず、揉捻鉢３と揉盤２の間に隙間があるので、茶葉はその隙間から出てきてしまいそうになり、そのときに、揉捻鉢３の外側に位置して、揉捻鉢３と一緒に揉盤上を回転している掃き込みブラシ７で茶葉を揉捻鉢３へ掃いて、戻す。掃き込みブラシ７の先端は揉盤２と略接するように設置してあるため、掃き込みブラシ７により揉盤２上を掃くことが可能である。茶葉の水分が均一になり、製茶揉捻機１での揉み込みが完了すると、分銅８を再び一番後ろへ移動し、茶葉取出部１１を開いて、茶葉の取出しを行なう。取出した茶葉はコンベヤ２２上に落下し、次の製茶装置へ搬送される。 Next, the operation of the tea making machine 1 will be described. The chute 21 puts the tea leaves into the bowl 3 on the board 2. At this time, the weight 8 is located at the rearmost side of the weight rail 9 so that no pressure is applied to the saddle platen 4. Since the culvert platen 4 has a conical shape and is not pressurized, the charged tea leaves enter the pestle 3 and under the crease platen 4. The pestle mortar 3 and the crushed platen 4 move horizontally on the laid platen 2, and the tea leaves are swallowed by pressure while rotating. While observing the state of the tea leaves, the weight 8 is moved to change the pressure, and the water inside the tea leaves oozes out to the surface, so that the water in the whole tea leaves is evenly mixed. Although the movement of the weight 8 may be performed by a person, it is convenient to set and control the position and time of the weight 8. When tea leaves move on the board 2, there is a gap between the rice bowl 3 and the board 2 even though the tea board is pressurized, so the tea leaves are likely to come out of the gap. At that time, the tea leaves are swept back to the mortar and mortar 3 with the sweeping brush 7 which is located outside the mortar and mortar 3 and rotating on the mortar together with the mortar and mortar 3. Since the tip of the sweeping brush 7 is installed so as to be substantially in contact with the board 2, the sweeping brush 7 can sweep the board 2. When the water content of the tea leaves becomes uniform and the brewing by the tea making machine 1 is completed, the weight 8 is moved back to the rear again, the tea leaf takeout part 11 is opened, and the tea leaves are taken out. The extracted tea leaves fall on the conveyor 22 and are conveyed to the next tea making apparatus.

図５は茶葉取出部１１の側面図であり、図６は茶葉取出部１１の取出揉盤１２と取出扉１４の取付図である。取出揉盤１２上には、ヒル１３が複数本溶接されており、取出扉１４は茶葉を取出すための開閉機構（図示しない）を備えている。取出揉盤１２と取出扉１４には、予めネジ孔１６、１７をあけておき、ネジ１５で装着する。 FIG. 5 is a side view of the tea leaf takeout part 11, and FIG. 6 is an installation view of the takeout board 12 and the takeout door 14 of the tea leaf takeout part 11. A plurality of hills 13 are welded on the takeout bar 12 and the takeout door 14 is provided with an opening / closing mechanism (not shown) for taking out the tea leaves. Screw holes 16 and 17 are made in advance in the takeout board 12 and the takeout door 14 and attached with screws 15.

図７はヒル１３が３本の取出揉盤１２Ａの平面図である。図８は図７の取出揉盤１２Ａを取出扉１４に装着し、茶葉取出部１１を閉じた場合の揉盤２全体図である。 FIG. 7 is a plan view of the takeout board 12 A having three hills 13. FIG. 8 is an overall view of the board 2 when the takeout board 12A of FIG. 7 is mounted on the takeout door 14 and the tea leaf extraction part 11 is closed.

図９はヒル１３が５本の取出揉盤１２Ｂの平面図である。図１０は図９の取出揉盤１２Ｂを取出扉１４に装着し、茶葉取出部１１を閉じた場合の揉盤２全体図である。 FIG. 9 is a plan view of the takeout board 12 B having five hills 13. FIG. 10 is an overall view of the board 2 when the takeout board 12B of FIG. 9 is attached to the takeout door 14 and the tea leaf extraction part 11 is closed.

図９のヒル１３を５本備えた取出揉盤１２Ｂから、図１０のヒル１３を３本備えた取出揉盤１２Ａに付替える場合を説明する。製茶揉捻機１に茶葉が入っていないとき、ネジ１５を外して、ヒル１３を５本備えた取出揉盤１２Ｂを取出扉１４から外し、ヒル１３を３本備えた取出揉盤１２Ａを取出扉１４にネジ１５で装着する。揉盤２全体は、図１０から図８へ変化する。 A case will be described in which the takeout board 12B having five hills 13 in FIG. 9 is replaced with the takeout board 12A having three hills 13 in FIG. When tea leaves are not contained in the tea making machine 1, the screws 15 are removed, the takeout board 12 B having five hills 13 is removed from the takeout door 14, and the takeout board 12 A having three hills 13 is taken out. 14 is attached with screws 15. The entire board 2 changes from FIG. 10 to FIG.

本実施例では取出揉盤１２、ヒル１３はステンレスであり、溶接してある。取出揉盤１２、ヒル１３をステンレスにすることにより、茶渋が付着しにくくなり、衛生的で、掃除の手間が省ける。本実施例ではステンレスであるが、その他茶渋が付着しにくい素材などでもよい。また、取出扉１４は従来どおり鋳物にすることにより、コストを下げることができる。 In the present embodiment, the takeout board 12 and the hill 13 are stainless steel and are welded. By making the takeout board 12 and the hill 13 stainless, it becomes difficult for the tea astringent to adhere, and it is hygienic and can save the labor of cleaning. In this embodiment, it is made of stainless steel, but may be other materials that are difficult to adhere to tea astringency. Further, the cost can be reduced by making the extraction door 14 as a conventional casting.
