、~用於冷卻材料貯槽1及圓筒部分2之冷卻部分、及一設 2 0 ;材料貯槽1中且能夠將材料Μ供應至圓筒部分2之材料 供應閥3。 此領域中，此“液體型冷凍甜點材料，，稱為“混合物”， 而此‘‘材料供應閥，，稱為“混合閥”。 材料貯槽1在其底部分處具有一材料導入路徑la。材料 5 200847932 導入路經la連接至圓筒部分2，而—材料 =路徑1a。並且，在__的底部;:底Γ面:材 二葉輪H用㈣崎料―的材 5 10 15 嶋分勒—躲齡及混合供應至圓筒部 刀内側的空氣及材料Μ之螺旋形授掉器以、 驅動攪拌器2a之馬達2c、及一用於抽取圓筒部分2中^迭 的^細點S之抽取部分2b。藉由驗抽取部分财的抽取 路徑且藉由授拌器旋轉來抽取圓筒部分2中的冷;東甜點s。 冷部部分係為-冷;東循環機構，其包括以經過硬管路 ㈣-迴路形狀依下述次序連接至彼此之_蒸發器、一壓 縮機、一冷凝器、一膨脹閥及類似物。 材料供應閥3具有由一外圓筒4及一内圓筒增成之一 雙重結構，如第19至21圖所示。 外圓筒4連接至材料貯槽丨中的材料導入路徑以且具有 位於材料貯槽1底部近處之一通孔4a。 、 自其上開口被插入外圓筒4之内圓筒5係在其下部分中 具有不同尺寸的複數個（圖中為兩個）通孔兄及北，其可導通 於外圓筒4中的通孔4a。通孔4a及通孔5a或5b形成一導通 孔。 並且外圓同4在其上端處具有定位切口槽扑及4C，而 且，内圓筒5在其上端處具有一突起件5c以接合於上述切口 槽4b或4c。並且，材料供應閥3在其上端開啟且亦作為一空 氣導入硬管以自其開口將空氣與材料M一起導入圓筒部分 20 200847932 2内0 具有上述結構的材料供應閥3係能夠改變外圓筒4與内 圓筒5之間的位置關係。藉由造成使各別圓筒内側與外侧相 互導通之通孔4a、5a及5b在位置中彼此呈重疊或位移，可 5 以開啟或關閉導通孔。 並且’可選擇内圓筒5中之較小通孔5a及較大通孔5b的 一者，且所選擇的通孔可重疊於外圓筒4中的通孔4a，其能 夠調整用於將材料貯槽丨及圓筒部分2彼此導通之導通孔的 尺寸。藉由調整導通孔的尺寸，流入圓筒部分2中之材料μ 10的流率可被調整至一預定範圍内，藉以將圓筒部分2中的材 料Μ及空氣之間的混合比值調整至一預定比值内，即便當 材料貯槽1中的材料Μ之液體位準L的高度改變時亦然。 當冷凍甜點S自圓筒部分2被抽取時，空氣及來自材料 貯槽1的材料Μ係經由材料供應閥3供應至圓筒部分2。 15 亦即，當導通孔尺寸維持在一恆定值時，由於材料貯 槽1中之材料Μ的液體位準L下降，施加於導通孔上之材料 Μ的壓力係減小。結果，經由導通孔流入圓筒部分2中之材 料Μ的流率減小。此外，被導入圓筒部分2中之材料供應閥 3中的材料Μ量減小，其使得空氣對於圓筒部分2中的材料“ 20之混合比值高於預定比值，故使冷凍甜點S的品質偏離一可 准許範圍。因此，由於材料液體位準L下降，可調整導通孔 的尺寸使其逐漸地增加，其可調整被供應至圓筒部分2之材 料Μ量藉以防止大幅改變。這可使圓筒部分2中的材料“及 空氣之間的混合比值維持在預定範圍内。 7 200847932

垂直硬管61並亦在其另一端開啟。並且，内圓筒部分53在 1〇其下部分處設有第二通孔53a並亦在其上部分的外周邊表 面上於其轴向方向中設有一突件53b。 另一方面，外圓筒部分52自其開啟端配合於内圓筒部 分53中並在其另一端關閉，而一第二水平軸15处係與外圓 筒部分52的關閉端部分一體地設置。 15 第二水平軸15汕係為一用於將稍後所述的連結機構 155的一第二臂158安裝至外圓筒部分52並用於將自連結機 構155轉移的力轉移至外圓筒部分52之軸。因此，第二水平 軸156b並非圓形軸且形成有具有譬如一等腰三角形柱形。 並且’外圓筒部分52在其下部分中具有可與内圓筒部 2〇分53中的第二通孔53&導通之第一通孔52a並亦在與第一通 孔52a相對之其内周邊表面中具有一凹形部分52b。凹形部

10孔52a及第二通孔53a之間的位置關係及導通孔5U的尺寸 變成上述者。 如第1至3圖所示，供應量調整部件5〇中，作為位移轉 移邛件之連結機構155係根據材料液體位準L高度將浮動構 件1的往上或往下運動轉換成外圓筒部分52及内圓筒部分 15 53繞一水平轴線相對於彼此的旋轉運動，其改變了雙重圓 筒部分51中之導通孔51a的尺寸（第4及5圖），如上述。亦即， 連結機構155的結構可改變導通孔51a的尺寸，如上述，以 調整被供應至圓筒部分20之材料μ量。 如第3圖所示，連結機構155包括在其相對端具有樞轉 20耦合部分之第一臂157及在其相對端具有樞轉耦合部分之 第二臂158。第一臂157在其一端處之樞轉耦合部分以及第 二臂158在其一端處之樞轉耦合部分係彼此樞轉式耦合使 其可搖擺。位於其另-端之第-臂157的樞轉柄合部分係柄

5樞轉耦合部分156c的轴梢端沿著各別推拔狀槽I58f移動 時，该對平行線性部分158b之間的間隙係由於其彈性變形 而增大，故能夠將樞轉耦合部分156c容易地插入樞轉耦合 部分158e中。 具有上述結構之連結機構155中，處於一其中使材料貯 10槽10充填有一材料Μ最高達到其上部分且因此使浮動構件 41在一上位置離開如第丨及2圖所示之狀態，第一及第二臂 157及158採取使其以一L形被彎折同時彼此耦合之姿態。 當材料貯槽10中的材料Μ供應至圓筒部分20時，液體 位準L逐漸下降。連帶地，浮動構件41如第6圖所示逐漸地 15下降’其造成第二臂158相對於第二水平軸156b往下搖擺 (在箭頭A方向中），藉以造成第一臂157及第二臂158彼此趨 近。 因為第二臂158往下搖擺，耦合至第二臂158之雙重圓

處於約7:3容積比值之一材料及空氣。並且，第1圖所示的 冷凍甜點製造機中，在一其中使材料貯槽10儲存一材料M 5最高達到其上限高度附近之狀態，材料…已流入垂直硬管 61中最高達到與材料貯槽1〇中的液體位準L高度相同之高 度，如第7(a)圖所示。在此時，在雙重圓筒部分51中彼此重 疊之由外圓筒部分52中的第〆通孔52a及内圓筒部分53中 的第二通孔53a所構成之導通孔51以系具有一較小尺寸，如 10 第4圖所示。 藉由開啟抽取部分23中的抽取路徑且藉由圓筒部分20 中的攪拌器旋轉來抽取一預定量的冷凍甜點S。在此時，如 第7(b)圖所示，一負壓力產生於圓筒部分20中，其由於圓筒 部分20中負壓力的吸力效應造成垂直硬管61的材料μ首先 15 流入圓筒部分20中。連帶地，垂直硬管61中之材料Μ的液 體位準L1係下降。 隨著垂直硬管61中之材料Μ的液體位準L1下降，，由 於材料貯槽10中材料Μ液體位準L高度與垂直硬管61中材 料L的液體位準L1南度之間差異及材料μ比重及類似因素 20之關係’材料貯槽10中的材料Μ施加至導通孔51a上之壓力 係逐漸變成大於雙重圓筒部分51中的材料Μ施加至導通孔 51a上之壓力。結果，材料貯槽1〇中的材料Μ逐漸地流入雙 重圓筒部分61的導通孔5la中（請見第8(a)圖）。 當冷凍甜點S被進一步抽取時，垂直硬管61中材料μ的 23

為此，即便當材料貯槽1〇中之材料…的液體位準L連續 地下降時，依此，材料貯槽1〇中材料M施加至導通孔5以上 的壓力逐漸地減小，可防止流過導通孔5U之材料觸流率 偏離-預定範圍。結果，可防止流人圓筒部分射的材料 Μ及空氣之間的混合比值偏離一預定範圍。 如上述，一預定量的冷凍甜點S係自圓筒部分20被抽取 複數次，其造成材料貯槽1〇中材料Μ的液體位準[高度逐漸

5料“加以設計。亦即，材料供應裝置中，將導通孔51a的尺 寸及其變化率設計成可使材料Μ與空氣之間的混合比值落 在一預定範圍内，即便若每當冷凍甜點8開始被抽取，材料 貯槽10中材料液體位準L的高度及垂直硬管61中材料液體 位準L1的高度在未進行冷凍甜點s抽取之時亦產生變動。這 Π)能夠自動地控制流入雙重圓筒部分51之材料M的流率成為 將造成材料Μ及空氣以一妥當比值供應至圓筒部分刈之一 流率。 藉由根據本發明的材料供應裝置及使用其之冷凍甜點 製造機，材料貯槽10中的材娜量係隨著冷;東甜點⑽上述 15逐漸地被抽取而減小，且當材料液體位準L下降至低於導通 孔51a時，材料Μ不再供應至圓筒部分2()。為此，較佳在液 體位準L高於導通孔51a時、諸如當雙重圓筒部扣曝露於 液體位準L上方的空氣之時使一操作者以材料糊充材料 貯槽10。並且，當材料貯槽10以材料州乍補充時，浮動構

INSTRUCTIONS: [Technical woven fabrics of the invention] Field of the Invention The present invention relates to a cold material manufacturing apparatus for a cold, east dessert manufacturing machine, and a cold-scented dessert manufacturing machine. More specifically, the present invention relates to a material supply apparatus for a cold bed dessert maker for producing a cold spot such as a soft ice fill or a milkshake. ί Previously, the winter standard] Background of the invention 10 f η is a schematic view of the dessert manufacturing machine from its side surface display. Figure 20 is a cross-sectional view showing the structure of a material supply valve used in a conventional cold-wheat dessert making machine. Figure 21 is a side cross-sectional view of a material supply valve used in a conventional East dessert making machine. With JP-A Νο. One of the machines described in 2002-65171, As a conventional frozen dessert system for the manufacture of frozen desserts such as soft ice cream and milkshakes & machine. As shown in Figure 19, The frozen dessert making machine includes a material storage tank for storage/night body type cold 'east dessert material 1、1 A cylinder for disturbing and cooling the cold bed dessert with the air into a cylindrical portion of the cold confectionery. , ~ used to cool the cooling portion of the material storage tank 1 and the cylindrical portion 2, And set a 2 0 ; The material sump 1 is capable of supplying the material enthalpy to the material supply valve 3 of the cylindrical portion 2. In this field, This "liquid type frozen dessert material, , Known as the "mixture", And this ‘‘material supply valve, , Known as the "mixing valve." The material storage tank 1 has a material introduction path la at its bottom portion. Material 5 200847932 The introduction path is connected to the cylinder portion 2 via la, And - material = path 1a. and, At the bottom of __; : Bottom page: Material 2 Impeller H (4) Raw material - 5 10 15 嶋 分 - 躲 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 及 a motor 2c that drives the agitator 2a, And an extraction portion 2b for extracting the fine points S of the cylindrical portion 2. Extracting the cold in the cylindrical portion 2 by extracting the partial extraction path and rotating by the agitator; East dessert s. The cold part is - cold; East Loop Agency, It includes an evaporator that is connected to each other in a hard pipe (four)-circuit shape in the following order, a compressor, a condenser, An expansion valve and the like. The material supply valve 3 has a double structure which is formed by an outer cylinder 4 and an inner cylinder. As shown in Figures 19-21. The outer cylinder 4 is connected to the material introduction path in the material sump and has a through hole 4a located near the bottom of the material sump 1. , The inner cylinder 5 from which the upper opening is inserted into the outer cylinder 4 has a plurality of (two in the figure) through-hole brothers and norths having different sizes in the lower portion thereof. It can be conducted through the through hole 4a in the outer cylinder 4. The through hole 4a and the through hole 5a or 5b form a through hole. And the outer circle and the 4 have a positioning slit slot and 4C at the upper end thereof, And, The inner cylinder 5 has a projecting piece 5c at its upper end to be engaged with the above-described slit groove 4b or 4c. and, The material supply valve 3 is opened at its upper end and also introduced as an air into the hard pipe to introduce air from the opening thereof into the cylindrical portion 20 together with the material M. 200847932 2 0 The material supply valve 3 having the above structure can change the outer cylinder 4 The positional relationship with the inner cylinder 5. By causing the through holes 4a to conduct the inner and outer sides of the respective cylinders, 5a and 5b overlap or displace each other in position, Can be 5 to open or close the via. And 'selecting one of the smaller through hole 5a and the larger through hole 5b in the inner cylinder 5, And the selected through hole may overlap the through hole 4a in the outer cylinder 4, It is capable of adjusting the size of the via hole for conducting the material storage tank and the cylindrical portion 2 to each other. By adjusting the size of the via holes, The flow rate of the material μ 10 flowing into the cylindrical portion 2 can be adjusted to a predetermined range, Thereby adjusting the mixing ratio between the material Μ and the air in the cylindrical portion 2 to a predetermined ratio, This is true even when the height of the liquid level L of the material 材料 in the material storage tank 1 is changed. When the frozen dessert S is extracted from the cylindrical portion 2, The air and the material from the material sump 1 are supplied to the cylindrical portion 2 via the material supply valve 3. 15 that is, When the via size is maintained at a constant value, Since the liquid level L of the material 中 in the material sump 1 decreases, The pressure of the material applied to the via holes is reduced. result, The flow rate of the material enthalpy flowing into the cylindrical portion 2 via the through holes is reduced. In addition, The amount of material in the material supply valve 3 introduced into the cylindrical portion 2 is reduced, It causes the mixing ratio of air to the material "20" in the cylindrical portion 2 to be higher than a predetermined ratio, Therefore, the quality of the frozen dessert S deviates from a permissible range. therefore, Due to the drop in the liquid level of the material, The size of the via hole can be adjusted to gradually increase, It can adjust the amount of material supplied to the cylindrical portion 2 to prevent a large change. This maintains the mixing ratio between the material "and the air in the cylindrical portion 2 within a predetermined range. 7 200847932 [No. 5] The invention solves the problem solved by the present invention. ¥知的冷_点制造机 needs to enable the operator to monitor the height of the liquid level of the material as needed. The money is selected according to the liquid level L of the material —. The inner diameter of the towel is the same as that of the towel. The inner cylinder is operated by the human body. That is, the operator needs to adjust the material supplied from the material storage tank 圆筒 to the cylindrical portion a. the amount. To do this, you need such complicated operations, And because the operator uses his/her hand to access the material, it also has concerns about hygiene. and, As above, As the liquid level of the material drops, The size of the via hole is increased in a 13⁄4 manner. Thereby, the resultant ratio between the material enthalpy and the air in the cylinder 2 is maintained within a predetermined ratio. however, Has the following problems. As shown in Figure 22, Until the size of the via hole is changed to the next size, the flow rate of the material μ flowing into the material supply valve 3 decreases as the liquid level l of the material 中 in the material sump decreases. This gradually increases the mixing ratio of the air supplied to the cylindrical portion 2 to the material enthalpy. and, The timing of the change in the size of the via hole depends on the operator. therefore, As shown by the broken line in Fig. 22, there is a case in which the mixing ratio between the material Μ and the air deviates from the predetermined ratio if the timing is greatly changed. As above, Conventional cold-sweet dessert making machines have the following problems, because the size of the via holes changes in a first-order manner, And because the via size is manually changed by an operator, The mixing ratio between the material Μ and the air supplied to the cylindrical portion 2 is not stable. Means for Solving the Problem 8 200847932 The present invention is produced by the above problems and is intended to provide a material supply device for a dessert making machine, It eliminates the need for operator operation based on the material level of the material.

In a state in which the liquid level L of the material Μ in the material storage tank 10 is at a higher position of 18 200847932, as shown in Fig. 1, The positional relationship between the first through hole 52a and the second through hole 53a is such that the size of the through hole V through hole 51a is small as shown in Fig. 4, Another aspect is that the liquid level has been lowered to the vicinity of the bottom portion of the material storage tank, The through hole 51 is ancient "丄σ 1 , 札)^ has a larger size, As shown in Fig. 5, FIG. 5 shows that the shape and size of the second through hole 53a in the inner cylindrical portion 53 and the width of the projection 53b are considered. The position of the first through hole, The shape and size of the first through hole 52a in the outer cylindrical portion 52 and the size of the concave portion 52b, And similar factors, The positional relationship between the first through hole 52a and the second through hole 53a according to the height of the material liquid and the size of the through hole 5U are changed to the above. As shown in Figures 1 to 3, Supply adjustment component 5, The coupling mechanism 155 as the displacement transfer member converts the upward or downward movement of the floating member 1 into the outer cylindrical portion 52 and the inner cylindrical portion 15 53 with respect to each other about a horizontal axis according to the material liquid level L height. Rotating motion, It changes the size of the via hole 51a in the double cylindrical portion 51 (Figs. 4 and 5), As above. that is, The structure of the link mechanism 155 can change the size of the via hole 51a. As above, The amount of material μ supplied to the cylindrical portion 20 is adjusted. As shown in Figure 3, The link mechanism 155 includes a first arm 157 having a pivoting coupling portion at its opposite end and a second arm 158 having a pivot coupling portion at its opposite end. The pivotal coupling portion of the first arm 157 at one end thereof and the pivot coupling portion of the second arm 158 at one end thereof are pivotally coupled to each other such that it can swing. The pivoting shank portion of the other end arm 157 is stalked to the first horizontal shaft 156a to allow the first arm rest 57 to swing. The second arm 158 is coupled to the second horizontal shaft 156b at the other end of the pivotal coupling portion at 19 200847932 to make the outer cylindrical portion 52 rotatable. The first arm 157 is formed to have a substantially domed shape, It has a minute portion 157a at one end and an orthogonally bent portion 157b at the other end portion thereof. In the part 157_ opposite end, An axial hole 157c as a pivotal coupling portion that can be rotatably inserted through the pair of horizontal shafts 156 is formed. In the end portion of the reading portion l57b, A shaft-shaped pivot coupling portion 156c is formed integrally with the body. The first #158 is also formed to have a quality? shape, It has a part and a part at one end, Similar to the first arm 157, Also, there is a parallel parallax of the pair at the portion opposite to the tearing of the bifurcation portion 1. At the end portion of the divided portion 158a, Formed with a - triangular hole as - will be fitted to the shank of the second horizontal axis with the shape of "isometric three Xiaoxian" And also in the part of the 5_ other end, An axial hole cut capable of being inserted through the second horizontal shaft 丨 (10) is formed as a huddle portion so that the second second horizontal shaft output is rotatable relative to the other end portion of the divided 4 minutes 158a. The partial and partial plates prevent the outer cylindrical portion 52 from being pulled out from the inner cylindrical portion 53. and, At the end portion of the pair of parallel linear portions, Forming a hole-shaped hinge portion l58e, It can be inserted into the shaft-combined portion i56c so that the ___ joint portion 156e can feed the end portion _ of the parallel linear portion (4), The transfer portion 15 (4) is clamped to the pivoting portion 156c of the first arm 157 by means of its pivotal support. And in the opposite surface of the end portion of the parallel linear portion 20 200847932 158b of the sister-in-part The push-out groove 158f' formed with a pair has a depth which gradually increases as the distance from the pivot coupling portion 158e in the upward direction perpendicular to the rib of the parallel linear portion 15 increases. Mounting the pivot coupling portion 156c to the pivot coupling portion 158ef, When the tip end of the pivotal coupling portion 156c moves along the respective push-out grooves I58f, The gap between the pair of parallel linear portions 158b is increased due to its elastic deformation. Therefore, the pivot coupling portion 156c can be easily inserted into the pivot coupling portion 158e. In the connection mechanism 155 having the above structure, In a state in which the material reservoir 10 is filled with a material Μ up to the upper portion thereof and thus the floating member 41 is separated from the upper position as shown in FIGS. 2 and 2, The first and second arms 157 and 158 assume a posture in which they are bent in an L shape while being coupled to each other. When the material 中 in the material storage tank 10 is supplied to the cylindrical portion 20, The liquid level L gradually decreases. Jointly, The floating member 41 is gradually lowered 15 as shown in Fig. 6 which causes the second arm 158 to swing downward with respect to the second horizontal axis 156b (in the direction of the arrow A), Thereby, the first arm 157 and the second arm 158 are brought closer to each other. Because the second arm 158 swings down, The outer cylindrical portion 52 coupled to the double cylindrical portion 51 of the second arm 158 is rotated in the direction of the arrow a, It causes the 20th through hole 52& The size of the via hole 51a is gradually increased by moving from the state of Fig. 4 to the state of Fig. 5 with respect to the second through hole 53a. and, Fig. 6 is a side view showing a state in which the floating member has been lowered in the embodiment. And as shown in Figure 6, The bent portion 157b of the joint mechanism 155 is 21 200847932 to prevent the first arm 157 and the second arm 158 from interfering with each other, And further, The concave portion 42b provides a gap for preventing the bottom portion of the floating member 41 from coming into contact with the double cylindrical portion 51, It can allow the floating member 41 to descend to the vicinity of the bottom portion of the material $slot 10 or to the bottom portion thereof. 曰 To this end, With this embodiment, Compared to the case in which the floating member 41 has a flat bottom surface, The swinging stroke of the second arm 158 is um + " JL 9 , It will: The extent to which the outer cylindrical portion 52 is rotatable. result, With the present embodiment, the process of the first through hole 52a with respect to the second through hole 53a can be ensured. Oh, Only the line 10 15 20 建 is created to cause the size of the via hole 51a to be accompanied by a drop in the liquid level rather than abruptly changing. , Again and because the floating member 4i can be lowered to the bottom of the material storage tank 1 (), surface, And further, The through hole 51a is placed in the double cylindrical portion y 4 knife, Even if the material liquid in the material storage tank 1 is only near the bottom neighbor, It is still possible to supply the material to the cylindrical portion 2〇. The material supply device F1 of the above-described structure may be made of a metal such as polyethylene or a metal such as stainless steel. The system is 4 in the cold according to the first embodiment; East Dessert away. The η ^ diagram of a material supplied from the material storage tank 至 to the cylindrical portion 20 is not shown - the material is supplied to the explanatory diagram according to the state of the first embodiment and the portion, And Fig. 8 is a view showing the state in which the material is supplied to the cylindrical portion according to the first embodiment. The cylinder 20 is stored in the frozen dessert manufacturing machine shown in Fig. 1, 22 200847932 A mixing ratio within a predetermined range to agitate and mix a material and air to make one of the frozen desserts, For example, in the case of cooling, in the case of soft ice cream, at about 7: 3 volume ratio material and air. and, In the frozen dessert making machine shown in Fig. 1, In a state in which the material storage tank 10 stores a material M 5 up to a vicinity of its upper limit height, The material... has flowed into the vertical hard tube 61 up to the same height as the liquid level L in the material storage tank 1〇, As shown in Figure 7(a). currently, The through holes 51 formed by the second through holes 52a of the outer cylindrical portion 52 and the second through holes 53a of the inner cylindrical portion 53 which overlap each other in the double cylindrical portion 51 have a small size. As shown in Figure 4, Figure 4. A predetermined amount of frozen dessert S is extracted by opening the extraction path in the extraction portion 23 and rotating by the agitator in the cylindrical portion 20. currently, As shown in Figure 7(b), A negative pressure is generated in the cylindrical portion 20, The material μ of the vertical rigid tube 61 first flows into the cylindrical portion 20 due to the suction effect of the negative pressure in the cylindrical portion 20. Jointly, The liquid level L1 of the material Μ in the vertical tube 61 is lowered. As the liquid level L1 of the material 垂直 in the vertical rigid tube 61 drops, , Due to the difference between the material Μ liquid level L height in the material storage tank 10 and the liquid level L1 south degree of the material L in the vertical hard tube 61 and the relationship between the material μ specific gravity and the similar factor 20, the material 材料 in the material sump 10 is applied to The pressure on the via hole 51a gradually becomes larger than the pressure applied to the via hole 51a by the material 中 in the double cylindrical portion 51. result, The material 〇 in the material reservoir 1 Μ gradually flows into the via hole 51a of the double cylinder portion 61 (see Fig. 8(a)). When the frozen dessert S is further extracted, The material μ of the vertical hard tube 61 23 200847932 The liquid level U is lowered to reach the inside of the cylindrical portion 20. Jointly, As shown in Figure 8(8), From (4) storage _ flow scale fox 51a read _ and vertical air tube 61 in the air system flow cylinder part 2 (), And then in the cooling condition, the material enthalpy and the working gas are authorized and mixed in the cylindrical portion 2〇, Therefore, the guide is reduced to ~/East dessert. currently, The air flowing into the cylinder portion is cooled by being mixed with the material crucible; East dessert. After the lamb's frozen dessert S is finished, As shown in the figure, Material 工 and work gas are no longer *in the cylinder 2〇, The material flows into the vertical tube 1 until its height reaches the material in the material reservoir 1G to close the liquid level. ~/ East dessert during the extraction period, The floating member 第 of the material in the material storage tank 1 [the liquid level L 卩 + ” 1 is also lowered. As the floating member 4丨 drops, The outer cylindrical portion η is rotated by the amount of the swing of the second arm 158 by the operation of the above-described joint mechanism I%, It continuously increases the size of the via hole 51a. to this end, Even when the liquid level L of the material in the material storage tank 1 is continuously decreased, Accordingly, The pressure applied to the conductive via 5 by the material M in the material storage tank 1 逐渐 gradually decreases. The flow rate of the material flowing through the via hole 5U can be prevented from deviating from the predetermined range. result, It is possible to prevent the mixing ratio between the material and the air which is partially injected by the flow cylinder from deviating from a predetermined range. As above, A predetermined amount of frozen dessert S is extracted from the cylindrical portion 20 a plurality of times, It causes the liquid level of the material Μ in the material storage tank 1 [the height gradually decreases. During this period, When the extraction of frozen dessert 8 is stopped, The material flows into the vertical rigid tube 61 until its height reaches the liquid level L height of the material in the material storage tank 1 as shown in Fig. 8(b). However, the liquid level LU 々 height of the material in the vertical tube 61 decreases as the frozen dessert s is extracted by 24 200847932. that is, Whenever the frozen dessert s is taken, The amount of material μ introduced into the vertical rigid tube 61 in the cylindrical portion 20 at the time of extracting the frozen dessert is reduced. The material supply device according to the present invention considers that the material in the vertical rigid tube 61 is "designed. that is, In the material supply device, The size of the via hole 51a and its rate of change are designed such that the mixing ratio between the material Μ and the air falls within a predetermined range. Even if the frozen dessert 8 starts to be extracted, The height of the material liquid level L in the material storage tank 10 and the height of the material liquid level L1 in the vertical hard tube 61 also vary when the frozen dessert s is not taken. This can automatically control the flow rate of the material M flowing into the double cylindrical portion 51 to a flow rate which will cause the material helium and air to be supplied to the cylindrical portion at a proper ratio. With the material supply device according to the present invention and the frozen dessert manufacturing machine using the same, The amount of material in the material storage tank 10 is followed by cold; East Dessert (10) The above 15 is gradually extracted and reduced, And when the material liquid level L falls below the conduction hole 51a, The material Μ is no longer supplied to the cylindrical portion 2(). to this end, Preferably, when the liquid level L is higher than the via hole 51a, An operator fills the material reservoir 10 with a material paste, such as when the double cylinder buckle is exposed to air above the liquid level L. and, When the material storage tank 10 is supplemented by the material state, The floating structure 20 pieces 41 rises and is connected, The supply amount adjusting unit 5 〇 performs an operation opposite to that when the floating member ^ is lowered, Therefore, the via hole is restored from its larger size to the state of Fig. 4 having a smaller size. and, - in general, This type of cold rolling dessert making machine, Cooling can be performed according to the heating cycle opposite to the refrigerating cycle—the temperature of the material Μ 〇 and the cylindrical portion is not heated to cause the material Μ and the cold rolling dessert to be thermally sterilized. currently, for example, A shield tube having an outer collar at its upper end can be inserted into the vertical rigid tube 61 to prevent conduction between the vertical tube 61 and the double cylindrical portion 51. This shielding is performed to prevent the material 中 in the material sump 10 from flowing into the cylindrical portion 2 through the via hole 51a, Even if the frozen dessert s in the cylindrical portion 2 is melted and separated into a material Μ and air, a space is formed in the cylindrical portion 2 。. Since the material supply device F has the above structure according to the first embodiment, The following advantages can be provided. 10 (Effect M) 15 20 The material level l of the material in the material slot 10 is detected by the floating member 41. Linkage mechanism 155 operates in conjunction with the detected height of liquid level L. and, The outer cylindrical portion 52 is rotated relative to the inner cylindrical portion 53 = the size of the through hole 5U is adjusted, In order to adjust the material supplied to the cylinder part. This can automatically adjust the value of the material river and the door of the air in the cylindrical portion 2〇 to a predetermined range. By means of Lord ^ Cold Ling dessert. One wants, in addition, It also provides a liquid level L height that is no longer required by the operator for complex operations and according to the liquid level [Dish ^ ^ Manually adjusting the amount of material μ supplied to the cylindrical portion 20 by a fine valve, , Second, black account. Still, For the operator, there is no need to insert his/her hand into the material storage tank 〇 /, This provides the advantage of improved hygiene. To operate the valve and, As shown in Figure 9, The size of the via hole is the material level L of the material in the product #, and the liquid level L of the material is continuously increased, and the material groove 10 is continuously increased. It can be 26 200847932 to stabilize the flow rate of the material 流入 flowing into the double circle 1 ^ portion 51. This prevents the mixing ratio between the material Μ and the air supplied to the cylinder 2 from deviating from the predetermined range. and, In Figure 9, For ease of description, The graphic representing the mixing ratio is marked as a line representing the ratio of hate ’. If the graphic line is not a straight line, there is no problem. As long as it falls within the predetermined range. (effect 1-2) and, The liquid level detecting member is a floating member 41 which floats on the material liquid level L in the material storage tank 1 and can be manufactured in a simple structure and at low cost without using an electric component. 10 and, The supply adjusting member used herein is a mechanical transfer of the displacement of the floating member 41 of the material sump 10 via a displacement transfer member to the double cylindrical portion 52 such that the outer cylindrical portion 52 and the inner cylindrical portion ^ Mechanisms that rotate relative to each other, A power source such as a motor for rotating the outer cylinder portion 52 and the inner cylinder portion 53 relative to each other is not employed. 5 is also 15 The supply of the wetting member may be constituted by a mechanism capable of utilizing the movement of the floating member 41 which moves with the change in the level of the material liquid level L in the material storage tank 1 as a motor power. to this end, The supply adjustment component can be manufactured in a simple structure and at low cost without using electrical components. (Effects 1-3) 20 and, The displacement transfer member is the joint mechanism 155 and thus can smoothly and smoothly shift the upward or downward displacement of the floating member 41 into a rotational force and reliably transfer it to the outer cylindrical portion 52. , and, Since the vertical rigid tube 61 is inserted into the hole of the floating member 41, The floating member 41 can be prevented from floating freely on the material liquid level, It may place the 27th 200847932 horizontal axis 156a_ at a position substantially above the second horizontal axis. This enables the coupling mechanism 155 to be operated such that the outer cylindrical portion 52 is rotated with high precision by an amount corresponding to the upward or downward displacement of the material liquid level L. (Effects 1-4) 5 Since the vertical rigid tube 61 is used as an air introduction member, It is no longer necessary to provide a separate component for introducing air into the cylindrical portion 2〇, This simplifies the structure of the material supply device F1. (Effect 1-5) Since the via hole 51a is placed in the lower portion of the double cylindrical portion 51, That is, when the liquid level L of the material in the material storage tank 1 is lowered to the vicinity of the bottom portion, the material can be stably supplied to the cylindrical portion. The following variations can be made to the first embodiment.

The figure 10(e) shows a case in which the first through hole 10 552a in the outer cylindrical portion 552 and the second through hole 553a in the inner cylindrical portion 553 have the same circular shape. Figure 10(f) shows a first through hole 652a in the outer cylindrical portion 652 and a second through hole 653a in the inner cylindrical portion 653 extending in the circumferential direction and arranged in the direction of the cylinder axis. The same two longer holes case. 15 and, The number of individual through holes can be appropriately changed to three or more. and, The size of the individual through holes can be made different from each other. and, Although not shown, The first and second through holes may be placed in the end surface of the double cylindrical portion. In this case, The end portion of the inner cylindrical portion is similar to the outer cylindrical portion, And the first and second through holes are formed in the closed end wall of the inner cylindrical portion 2〇 and the outer cylindrical portion, Located around the second horizontal axis. The shapes of the first and second through holes are curved as described above, And triangles, rectangle, Round and similar shapes. Ya, The shapes and combinations of the first and second through holes are not limited to the above. And can also be combined with; ί; The first and second through holes of the same shape and the first and second through holes of different numbers 29 200847932. (Second Modified Example of First Embodiment) FIG. 11 is a view showing a second modified example of the first embodiment. The second horizontal shaft 156b of the joint mechanism according to the first embodiment can be placed in the inner cylindrical portion 753 of the double 5-cylinder portion, As shown in Figure 11. In this case, A cylindrical portion 752 having an open opposite end is electrically connected at one end thereof and connected to a vertical rigid tube. and, An inner cylindrical portion 753 is closed at one end thereof with an end wall 753a having an outer diameter larger than the inner diameter of the outer cylindrical portion 753, The second horizontal shaft 156b is formed integrally with the end wall 753a. and, The open end portion of the inner cylindrical portion 10 753 is inserted and mounted to the outer cylindrical portion 752. And, A first through hole 752a and a second through hole 753a are formed in the lower portion of the outer cylindrical portion 752 and the inner cylindrical portion 753. and, Preferably, A concave portion and a protruding member as described with reference to Fig. 3 are disposed in the outer cylindrical portion 752 near the opening portion and on the inner cylindrical portion 753 15 near the end wall 753a, Thereby, the range of rotation of the inner cylindrical portion 753 is restricted. (Third Modified Example of First Embodiment) FIG. 12 is a view showing a third modified example of the first embodiment. Fig. 13 is a side view showing a material supply device according to a third modified example of the first embodiment. 20 As shown in Figure 12, The link mechanism may be provided with a plurality of first horizontal axes 156a in the vertical direction. With this, A pair of first horizontal axes 156a may be selected from the first horizontal axis 156a of the complex pair at different vertical positions, And the first arm 157 can be pivoted with it; the horse is as shown in Fig. 13, It is capable of changing the height of the axial hole 157c relative to the floating member 41 (see Fig. 3) and the mounting angle between the first arm 157 and the second arm 158 of 30 200847932 in the coupling mechanism 155. result, For the same height position of the floating member 41, The size of the via holes in the double cylindrical portion 51 can vary with the position of the first horizontal axis 15 selected. for example, When the material used here has a higher viscosity, It is possible to take measures to make the size of the via hole slightly larger than the case where the viscosity is low. In addition, the position of the horizontal axis 156a of the younger brother is used by the hunter. Variations in the size of the vias relative to the amount of drop in the floating member can be varied. (Fourth modified example of the first embodiment) The floating member 41 shown in Fig. 2 and the like is only required to have a hole sufficient to prevent the floating member 41 from being horizontally broken from the vertical rigid tube 61. therefore, The floating member 41 may have a C shape, Horseshoe or similar shape, And ring. and, The floating member 41 may be made of a foamed material such as foamed plastic. and, The buoyancy applied to the floating member 41 floating on the material liquid level 1 in the material reservoir 1 depends on the weight of the floating member 41, The amount of air in the floating member 15 41 and the like. therefore, The method of adjusting the weight of the ampoule to the floating member 4i or introducing the water into the floating member body portion π by a buoyancy force, The same effect as the third modified example described above can be provided, That is, the effect of the position of the first horizontal axis 156a relative to the liquid level of the material is changed. (Fifth Modified Example of First Embodiment) 20 Although the description has been made with reference to Figs. 1 to 3 and Fig. 6 - in which the 157th portion of the joint mechanism 155 is provided with a bent portion (four), The bent portion may be disposed in the first arm 158 or the folded portion may be disposed in the first arm 157 and the second arm 158. and, The bent portion may have a curved shape, And - a folded shape at right angles. 31 200847932 (Sixth Modification of First Embodiment) Although the case where the first arm 157 and the second arm 158 are used as the link mechanism has been described with reference to FIGS. 1 to 3 and FIG. A single _ arm can be used. In adopting this one-armed case, The single arm is provided with a sleeve at its opposite end in the longitudinal direction while preventing sliding relative to the vertical rigid tube 61, and the axial direction (four) side, (d) (4) The length of the opposite end is substantially equal to the sum of the distance from the third horizontal axis 156c to the axial hole and the distance from the axial hole and the axial hole 1586. In this case, when the floating member 41 is lowered, the floating member q is required to be self-verting from the vertical. Therefore, The floating member 41 does not have a cylindrical portion 42a and a concave portion 42b. (Second Embodiment) The second embodiment is similar to the first embodiment in that the material supply device in the frozen dessert maker includes a liquid level detecting member, a supply adjustment member and an air introduction member, However, it differs from the first embodiment in its structure. The second embodiment will be described below, Mainly related to the difference from the first embodiment. Fig. 14 is a view showing the material supply device according to the second embodiment, and Fig. 15 is a conceptual view for explaining the following facts. If a pin 85 drops, This causes a first through hole 81a to rotate, Thereby, the size of a via 20 is gradually increased. In the material supply device F2, The liquid level detecting member is an annular floating member 241 that floats on the liquid level of one of the frozen food materials in the material storage tank 10. The floating member 241 has a flat bottom portion and does not have the concave portion 4 2 b as in the floating member 41 according to the first embodiment (see Figs. 1 and 3 32 200847932).

The via holes % are formed from portions of the first via holes and the second via holes 82a which are laid on each other. The displacement transfer member shifts the upward and downward displacement of the floating member 241 to the double cylindrical portion 80 such that the outer cylindrical portion 81 and the inner cylindrical portion are called to rotate relative to each other' which changes the size of the above-described through hole 86, In order to adjust the amount of material supplied to the round part. Ya, Fig. 14 shows a state in which the outer cylindrical portion 81 has been pulled out from the inner cylindrical portion 82. Wherein the inner cylindrical portion 82 is in a liquid-tight state: 15 is connected to the material introduction path in the bottom portion of the material storage tank 1Q. More precisely, The outer cylindrical portion 81 is a vertical rigid tube extending from the bottom portion of the material reservoir 1 to the upper portion thereof. The inner cylindrical portion 82 is also - vertical: The official' has a flange at the lower end that will contact the bottom portion of the material storage tank 1 And also has a concave peripheral groove under the outer flange to fit therein; § The material inserted into the material storage tank acts as an ankle ring when it is introduced into the path. ^ ί 猎 The cone assembled by inserting the inner cylindrical portion 82 into the outer cylindrical portion 81 has an outer air introduction bee at its upper portion and is at: The straight direction is installed in the material storage tank. 33 200847932 installed in the material storage tank 1 by the inner circular double cylindrical portion 82 cylindrical portion 80 = heavy cylindrical portion 80, The external air introduction tether is connected to the inside of the cylindrical portion by ^I, And therefore, Also as an air introduction part. The rotation mechanism of the transfer mechanism ^ moving side up or down is converted into each other. Mouth 邛 / knife 82 relative

and a lock 85 is attached to the floating member 241 and inserted into each other. The guide slit in the outer cylindrical portion 81 is, for example, a longitudinal guide slit extending in the longitudinal direction of the cylinder and also serving as the first through hole described above. The guide slit 84 formed in the inner portion 82 is, for example, a spiral guide slit and also serves as the second through hole. That is, the first through hole and the second through hole 82a also have a function of guiding the direction of movement of the pin 85. The _L-shaped member which can be disposed on the bottom surface of the floating member 241 is formed by forming a threaded hole in a mounting portion 87 and also by detachably screwing the pin 85 having a male thread to the threaded hole. The pin 85 is mounted to the floating member 2〇241. By this action, after the double cylindrical portion 80 is inserted into the hole of the floating member 241, the pin 85 can be attached to the mounting portion 87 and inserted into the first and second through holes 81a and 82a to assemble it. And, as shown in Figs. 14 and 15, the second through hole 82a has a width which gradually increases toward the lower side. If the pin 85 descends along the first through hole § ia and the second through 34 200847932 hole 82a as the floating member 241 descends, this will rotate the outer cylindrical portion 81 and the inner cylindrical portion 82 relative to each other. This will gradually increase the size of the via hole 86 which is constituted by the portions of the first through hole 81a and the second through hole 82a which are laid on each other, wherein the pin 85 is inserted into the covering portion. In the second embodiment, as shown in Figures 15 and 15, the inner cylindrical portion 82 is fixed to the material sump 10 and, therefore, with the lowering of the floating member 241, the outer cylindrical portion 81 and the floating member for mounting the pin 85 241 rotate together. With the rotation of the outer cylindrical portion 81, the position of the via hole % is lowered, and the size of the via hole 86 is gradually increased. Referring to Figures 1, 14 and 15 for the description, in the second embodiment having the above structure, the distance from the material liquid level L in the material reservoir 10 to the via hole 86 present at the position of the pin 85 is maintained at A constant value, even if the material liquid level L height changes. For this reason, even if the height of the material liquid level L changes, the via hole 86 exists at a position substantially maintaining a constant distance from the via hole 86 to the body material L level L. When cold; the east dessert S is withdrawn from the frozen dessert making machine according to the second embodiment, the material 〇 in the double cylindrical portion 8〇 first flows into the space in the cylindrical portion 2〇. Then, when the material liquid level L in the double cylindrical portion 8〇 is lowered to the vicinity of the via hole 86, the material Μ in the material reservoir 1〇 starts flowing into the double cylindrical portion 80 via the 20 via hole 86. When the material liquid level L in the material introduction path 11 reaches the inside of the cylindrical portion 2, air is also supplied to the inside of the cylinder 20, and the material μ and air are actuated and cooled therein. Then, when the frozen dessert S is completely extracted, the liquid level L of the material which continuously flows into the double cylindrical portion 8 is raised to the same height as the material level of the material storage tank 1 2008 35 200847932. During this period, the pin 85 is rotated along the spiral second through hole 82a and the linear first through hole 81& and is gradually rotated by the lowering of the material liquid level l in the material storage tank 1 (), which gradually increases the through hole. The size of 86 is thereby gradually increased by 5 plus the flow rate of the material μ flowing into the material reservoir 10 in the double cylindrical portion 80. In the second embodiment, the material level L from the material reservoir 10 to the via 86 is obtained. The distance between them is rarely changed, and therefore even when the material liquid level L in the material storage tank 1 改变 changes, the material in the material storage tank 1 “ "the pressure applied to the 10 via holes 86 is maintained at a constant quality." The mutual value. However, the amount of material in the double cylindrical portion 80 varies depending on the height of the material liquid level L in the material storage tank 1 。. That is, whenever the frozen dessert 8 is extracted, and thus the material storage tank 10 When the material liquid level L height is lowered, the amount of material in the double cylindrical portion 80 flowing into the cylindrical portion 2 is reduced. 15 In order to compensate for the material enthalpy reduction in the double cylindrical portion 80, the second embodiment In the middle of the 'brother ^ one through hole 82a visibility is down The direction gradually increases, which increases the material flow rate of material flowing into the material reservoir 1 in the double cylindrical portion 80, whereby the mixing ratio between the material and the air supplied to the cylindrical portion 20 is maintained at a predetermined rate. In the second embodiment, in consideration of the fact that the mixing ratio between the material enthalpy and the air supplied to the cylindrical portion 20 is maintained within a predetermined range, the design is designed as a spiral guiding slit. The width of the second through hole 82a, the width of the first through hole 81a, the diameter of the pin 85, and the like increase rate. With the second embodiment, in addition to the above-described effect 第一 of the first embodiment and 1_2 36 200847932, The following effects (Effect 2-1) The double cylindrical portion 8〇 also functions as an air introduction member. Further, the displacement transfer member is formed by the pin 85 attached to the floating member 241 and the outer ring 5 and the inner circle 81 and the inner circle The different guiding slits in the peripheral wall of the barrel portion 82 are formed. For this reason, the material supply device can be made with a smaller number of components, a simpler structure, and lower cost. The following variations can be made for the second embodiment. (First modified example of the conventional embodiment) 10 A plurality of threaded holes may be vertically formed in an attachment portion 87 having an L-shaped member to mount the pin 85 to the floating member 241, which is capable of changing the position at which the pin 85 can be mounted. Thereby, for the same height position of the floating member 241, the size of the through hole 86 in the double cylindrical portion 80 can vary depending on the height of the selected position 15 at which the pin 85 can be mounted. For example, in the material ¥ has a higher In the case of high viscosity, it is known that the size of the via hole is slightly larger than when the viscosity is low. And, as in the fourth modification of the first embodiment, a weight or water can be introduced into the floating member. The buoyancy is adjusted in 241 to change the position of the pin 85 relative to the material level L of the material in the 20 material reservoir 10. (Second Modification of Second Embodiment) The pin may be formed of a coiled elastic or elastic member made of a rubber or an elastic plastic and may be fixed to the floating member (4). Thereby, when the floating member 241 is assembled and disconnected from the double cylindrical portion 8G, the pin is elastically deformed and thus will not interfere with assembly and disconnection. Also, in this example, the other through hole which is the same as the first through hole 81a may be formed at the same position as the first through hole 81a in the outer cylindrical portion 81 by a deviation of 18 degrees from the same as the one through hole 82a. The other through hole is also formed at a position offset from the second through hole 82a in the inner circular cylindrical portion 82 by 180 degrees and further, the pair of pins may be disposed at positions opposite to each other by 180 degrees. Thereby, the load applied to a single pin can be reduced. Further, if a through hole is not added to the inner cylindrical portion 82, a through hole pin guiding groove formed in the peripheral wall of the inner cylindrical portion may be employed. Also, the structure can be applied to a pin made of a gold genus or a hard plastic. (Third Modification of Second Embodiment) The second through hole 82a in the inner cylindrical portion 82 may have a constant width, and the first through hole 81a in the outer cylindrical portion 81 may have a gradual downward direction Increase one width. Further, both of the second through hole 82a and the first through hole 81a may have a width which gradually increases in the downward direction. (Third Embodiment) Fig. 16 is a view showing a material supply device according to a third embodiment. The difference between the third embodiment and the second embodiment is that a spiral first through hole 181a is also formed as a guide slit in the outer cylindrical portion 181 of the double cylindrical portion 18A, and also serves as A linear second through hole 182a of a guide slit is formed in the inner cylindrical portion 182, but other structures are substantially similar to those of the second embodiment. Further, in Fig. 16, the same components as those of the second embodiment 38 200847932 are denoted by the same reference numerals. In this example, as shown in Fig. 16, at least one of the first through hole 181a and the second through hole 182a is formed to have a width which gradually increases in the downward direction. According to the material supply device F3 of the third embodiment, a pin 85 linearly descends along the second through hole 182a in the inner cylindrical portion 182, and the first through hole 181a which is in contact with the pin 85 and slides relative thereto The edge portion receives one of the forces in the circumferential direction, thereby causing the outer cylindrical portion 181 to rotate. Further, the size of the through hole 86 into which the pin 85 is inserted (see Fig. 15) is gradually increased, whereby the flow rate of the material enthalpy flowing into the double cylindrical portion 180 from the material 10 sump 10 is gradually increased, similarly In the second embodiment. With the third embodiment, the same effects as the above-described effects 1-1 and 1-2 of the first embodiment and the above-described effect 2-1 of the second embodiment can be provided. (Modified Example of Third Embodiment) The first, second and third modified examples of the second embodiment can be applied to the third embodiment. (Fourth Embodiment) The fourth embodiment is similar to the second and third embodiments in that the structure of the material introduction path 20 for connecting the double cylindrical portion to the material reservoir (not shown) is different from that of the 14th and Figure 16 shows the second and third embodiments. That is, with the second embodiment (similar to the third embodiment) as described, in the second embodiment, the inner cylindrical portion 82 of the double cylindrical portion 80 is connected and fixed to the material storage tank 10. The material introduction path 11 rotates the outer cylindrical portion 81, but in the fourth embodiment, the outer cylindrical portion 81 is joined and fixed 39 200847932 to the material introduction path u in the material reservoir 以 to rotate the inner cylindrical portion 82 In the fourth embodiment, a flange which is to be in contact with the bottom portion of the material reservoir 1 and a concave peripheral groove for a loop are formed in the lower portion of the outer cylindrical portion 581. Further, the respective through holes 81a and 82a formed in the outer cylindrical portion and the inner cylindrical portion, and the structure and the like for attaching the pin 85 to the floating member 241 are similar to those of the second embodiment. With the fourth embodiment, the same effects as those of the above-described effects 1-1 and 1-2 of the first embodiment and the second embodiment can be provided. The first and third modified examples of the second embodiment can be applied to the fourth embodiment. (Fifth Embodiment) Fig. 17 is an explanatory view showing a material supply device F5 according to the fifth embodiment. The fifth embodiment is similar to the second and third embodiments including the floating member 241 and the pin 85, but differs from the second and third embodiments in that the floating member 241 is used together with the material liquid level L height. Upward or downward movement is converted into a structure of a moving direction changing mechanism of the rotational movement of the outer cylindrical portion 281 and the inner cylindrical portion 282 with respect to each other, and a first through hole 281a of the double cylindrical portion 280 and The second through hole 282a. Further, in Fig. 17, the same components as those of the second and third embodiments are denoted by the same reference numerals. The fifth embodiment will be mainly described below with respect to differences from the second and third embodiments. The motion direction changing mechanism according to the fifth embodiment includes a longitudinal guide slit 283 formed in an axial direction in the peripheral wall of the outer cylinder portion 281 of 40 200847932, and is formed diagonally in the peripheral wall of the inner cylindrical portion 282. The diagonal guide groove 285 and a pin 185 detachably mounted to the floating member 241. The pin 185 is inserted into the longitudinal guide slit 283 and is slidable along the diagonal guide groove 5 285 at its tip end. In the double cylindrical portion 280, the circumferential range in which the diagonal guide slits 285 are formed in the inner cylindrical portion 282 is the range of rotation of the outer cylindrical portion 281 and the inner cylindrical portion 282 with respect to each other. Further, the first through hole 28la is formed to have a long hole shape elongated in the circumferential direction at a position where the slit 10 is not present in the longitudinal direction, and is located in the lower portion of the peripheral arm of the outer cylindrical portion 281. The second through hole 282a is formed to have a long hole shape which is long in the circumferential direction at a position where the diagonal guide slit 285 is absent, and is located in the lower portion of the peripheral wall of the inner cylindrical portion 282. The first through hole 281a and the second through hole 282a are placed at the same height and also at positions where the outer cylindrical portion 281 and the inner cylindrical portion 282 are rotated relative to each other. Fig. 18 is a conceptual diagram for explaining the fact that if the pin 85 is lowered, this causes the outer cylindrical portion 281 to rotate, thereby gradually increasing the size of the via hole 286 in the fifth embodiment. 20, by the fifth embodiment having the above structure, as shown in FIGS. 17 and 18, when the pin 85 is lowered along the longitudinal guiding slit 283 and the diagonal guiding groove 285 as the floating member 241 is lowered, the pin 185 is The one side edge of the longitudinal guiding slit 283 is pushed in the circumferential direction, thereby causing the outer cylindrical portion 281 phase f to rotate about the inner cylindrical portion 282: 41 200847932 The first through hole 28h of the mouth moves in the circumferential direction with respect to the second through hole 282a, thereby gradually increasing the size of the through hole 286 formed by the first through hole 28u and the first through hole 282a which are overlapped with each other. This increases the material flow rate into the material reservoir in the dual barrel portion 80. With the fifth embodiment, the same effects as the above-described effects 1-1 and 1-2 of the first embodiment and the above-described effect 2_丨 of the second embodiment can be provided. (Sixth embodiment) In the fifth embodiment shown in Fig. 17, the inner cylindrical portion 282 of the double cylindrical portion 28 is connected and fixed to the material introduction path 10 in the material tank 1 后 to be rotated The outer cylindrical portion 28 is, but in the sixth embodiment, the outer cylindrical portion 281 is joined and fixed to the material introduction path n in the material reservoir 1 to rotate the inner cylindrical portion 282 (not shown). In the sixth embodiment, a flange which is to be in contact with the bottom portion of the material reservoir 1 and a concave peripheral groove for a ring are formed in the lower portion of the outer cylindrical portion 15 281. Further, the guide slits and guide grooves respectively formed in the outer cylindrical portion 281 and the inner cylindrical portion 282, the structure for mounting the pin to the floating member, and the like are similar to those of the fifth embodiment. With the sixth embodiment, it is possible to provide the same effects as the above-described effects 1 _ 1 and 1-2 of the first embodiment and the above-described effect 2-1 of the conventional embodiment. 20 (Modified Examples of Fifth and Sixth Embodiments) The first and second modified examples of the second embodiment can be applied to the fifth and sixth embodiments. Moreover, the shapes and combinations of the first through hole and the second through hole according to the fifth and sixth embodiments can be properly modified as in the first modification of the first embodiment. 42 200847932 ο and the fifth and sixth implementations In the example, a pair of angular guiding slits may be formed in the outer cylindrical portion, and a longitudinal guiding groove may be formed in the inner cylindrical portion.
