Abstract

A floating member 41 floating near the liquid level L of a material M in a material tank 10 is descended as the height of the material liquid level L is decreased. The descending movement is converted into rotational movement of an outer cylinder portion in a double cylinder portion 51. The rotational movement automatically changes the size of a communication hole which is constituted by the overlaid portions of a through hole provided in an inner cylinder portion and a through hole provided in the outer cylinder portion in the double cylinder portion 51. This change can be optimized through the shapes of the through holes, which enables maintaining the ratio between the material M supplied from the material tank 10 to a cylinder portion 20 and air supplied from a vertical pipe 61 to the cylinder portion 20 at a constant value within a required range.

Second arm 158 also forms has the shape that is essentially Y shape, and an end that is similar to the first arm 157, the second arms 158 has forked section 158a, and also has pair of parallel linear segment 158b in the part relative with forked section 158a.

An end at forked section 158a is formed with the tri-angle-holed 158c as the pivot coupling part; This tri-angle-holed 158c will be assembled to the second trunnion axis 156b of the shape with isosceles triangle post; And also be formed with axis hole 158d as the pivot coupling part in the other end of forked section 158a; This axis hole 158d makes time second trunnion axis 1156b can pass this axis hole 158d and inserts, thereby the inferior second trunnion axis 1156b can be with respect to the other end rotation of forked section 158a.Forked section 158a prevents that urceolus part 52 is drawn out inner cylindrical portion 53.

In addition; Be formed with hole shape pivot coupling part 158e in this end to parallel linear part 158b; This hole shape pivot coupling part 158e makes axle shape pivot coupling part 156 can pass this hole shape pivot coupling part 158e and inserts; Make that an axle shape pivot coupling part 156c can be with respect to the end rotation of parallel linear part 158b, thereby this is clipped in the middle this pivot coupling part 156c with the mode of the pivot coupling part 156c that supports the first arm 157 pivotly to parallel linear part 158b.In addition; In being provided with this apparent surface of pivot coupling part 158e to the end of parallel linear part 158b; Be formed with a pair of cone tank 158f, the degree of depth of this cone tank 158f is along with increasing and increase gradually along the distance of leaving pivot coupling part 158e perpendicular to the upwards direction of parallel linear part 158b.Pivot coupling part 156c is being installed in the process of pivot coupling part 158e; When the shaft end of pivot coupling part 156c moves along corresponding cone tank 158f; Owing to its strain increases, this makes pivot coupling part 156c can easily insert pivot coupling part 158e to the gap between the parallel linear part 158b for this.

In the linkage with aforementioned structure 155; The material M that fills in material tank as depicted in figs. 1 and 2 10 reach its top and therefore floating part 41 be present under the state of upper position, the one 157 and second arm 158 presents the form of L shaped bending when being coupled to each other.

When the material M in the material tank 10 was supplied to a tin part 20, liquid level L reduced gradually.In this process, floating part 41 descends as illustrated in fig. 6 gradually, and this makes second arm 158 swing with respect to the second trunnion axis 156b downward (in the direction of arrow A), thereby makes the first arm 157 and second arm 158 closer to each other.

Because second arm 158 is to lower swing; Therefore the urceolus part 52 that is connected to the bitubular part 51 of second arm 158 is rotated in the direction of arrow A; This makes the through hole 52a that wins move to the state of Fig. 5 with respect to the second through hole 53a from the state of Fig. 4, thereby increases the size of intercommunicating pore 51a gradually.In addition, Fig. 6 is the side view that is illustrated in the state that floating part has descended in this embodiment.

In addition; As shown in Figure 6; The sweep 157b of linkage 155 prevents that the first arm 157 and second arm 158 from interfering with each other; And in addition, recessed portion 42b provides the space so that prevent the bottom contact bitubular part 51 of floating part 41, and this allows floating part 41 to drop near the bottom of material tank 10 or drops to its bottom.

Therefore, for this embodiment, can increase the oscillating stroke of second arm 158, the situation that has smooth basal surface with floating part 41 is compared, and this has increased urceolus part 52 rotatable scopes.As a result,, can guarantee the longer movement travel of the first through hole 52a, therefore make the size of intercommunicating pore 51a change lenitively along with the decline of liquid level rather than suddenly change with respect to the second through hole 53a for this embodiment.

In addition; Because floating part 41 can drop near the bottom of material tank 10 or drop to its basal surface, and in addition, intercommunicating pore 51a is placed on the bottom of bitubular part 51; Even therefore the liquid level L of the material in the material tank 10 drops near the bottom, also can material be fed to a part 20.

Material feeding mechanism F1 with aforementioned structure can be by such as the plastics of polyacetals or such as stainless made.

To describe below from supplying the state of materials to tube part 20 according to the material tank the frozen-dessert making machine of first embodiment 10.

Fig. 7 representes that material is supplied to the key diagram according to the tube state partly of first embodiment, and Fig. 8 is that expression material and air are supplied to the key diagram according to the tube state partly of first embodiment.

In frozen-dessert making machine shown in Figure 1; The storage of tube part 20 through under freezing state with preset range in blending ratio stirring and composite material and air and the frozen confectionery S that processes of (for example under the situation of soft ice cream, the volume ratio of material and air is approximately 7: 3).In addition, in frozen-dessert making machine shown in Figure 1, under near the state of material tank 10 storage medium M its upper limit height, material M flowed into VERTICAL TUBE 61 reach with material tank 10 in the identical height of height of liquid level L, shown in Fig. 7 (a).At this moment, the intercommunicating pore 51a that is made up of first through hole 52a in the urceolus part 52 that in bitubular part 51, overlaps each other and the second through hole 53a in the inner cylindrical portion 53 has less size, and is as shown in Figure 4.

Through opening the extraction path of extracting in the part 23 and passing through the agitator rotation in the tube part 20, extract the frozen confectionery S of scheduled volume.At this moment, shown in Fig. 7 (b), in tube part 20, producing negative pressure, this negative pressure makes the material M in the VERTICAL TUBE 61 at first flow into a tube part 20 owing to the swabbing effect of the negative pressure in the tube part 20.Simultaneously, the liquid level L1 of the material M in the VERTICAL TUBE 61 descends.

Liquid level L1 decline along with the material M in the VERTICAL TUBE 61; Because the relation of the difference between the height of the height of the liquid level L of the material M in the material tank 10 and the liquid level L1 of the material M in the VERTICAL TUBE 61 and proportion of material M or the like, the material M in the material tank 10 is applied to pressure on the intercommunicating pore 51a and becomes gradually and be applied to the pressure on the intercommunicating pore 51a greater than the material M in the bitubular part 51.As a result, the material M in the material tank 10 flows among the intercommunicating pore 51a of bitubular part 61 (referring to Fig. 8 (a)) gradually.

When further extraction frozen confectionery S, the liquid level L1 of the material M in the VERTICAL TUBE 61 descends to reach the inside of a part 20.Simultaneously, shown in Fig. 8 (a), flow into tube part 20 through intercommunicating pore 51a from material M and the air the VERTICAL TUBE 61 that material tank 10 flows out, then, material M and air are stirred in tube part 20 under the state of cooling and mix, thereby form frozen confectionery.At this moment, the air of inflow tube part 20 is introduced into frozen confectionery through mixing with material M.

Then, after the extraction of frozen confectionery S was accomplished, shown in Fig. 8 (b), material M and air no longer flowed into a part 20, and material inflow VERTICAL TUBE 61 highly reaches the liquid level L of the material M in the material tank 10 up to it.

During the extraction of frozen confectionery, when the liquid level L of the material M in material tank 10 descended, the floating part 41 shown in Fig. 1 also descended.Along with floating part 41 descends, urceolus part 52 is owing to the amount corresponding to the oscillating quantity of second arm 158 is rotated in the running of aforementioned linkage 155, and this has increased the size of intercommunicating pore 51a continuously.

Therefore, though the liquid level L of the material M in the material tank 10 descends continuously and therefore the pressure that is applied on the intercommunicating pore 51a of the material M in the material tank 10 reduce gradually, the flow rate that also can prevent to flow through the material M of intercommunicating pore 51a departs from preset range.As a result, prevented that the material M of inflow tube part 20 and the blending ratio between the air from departing from preset range.

As stated, repeatedly extract the frozen confectionery S of scheduled volumes from tube part 20, this makes the height of liquid level L of the material M in the material tank 10 descend gradually.During this period; When the extraction of frozen confectionery S stopped, material flowed into VERTICAL TUBE 61 and highly reaches in the preceding text height with reference to the liquid level L of the material in the described material tank 10 of figure 8 (b) up to it, still; When extracting frozen confectionery S, the height of the liquid level L1 of the material in the VERTICAL TUBE 61 all reduces at every turn.In other words, when extracting frozen confectionery S, the amount that when extracting frozen confectionery, is introduced into the material M in the VERTICAL TUBE 61 of a part 20 all reduces at every turn.

The amount of the material M in the VERTICAL TUBE 61 has been considered in the design of material according to the invention feeding mechanism.In other words; In the material feeding mechanism; The size of intercommunicating pore 51a and the speed of change thereof are designed to; Even when beginning to extract frozen confectionery S, variation has taken place in the height of the height of the material liquid level L in the material tank 10 when not carrying out the extraction of frozen confectionery S and the material liquid level L1 in the VERTICAL TUBE 61, and the blending ratio between material M and the air also drops in the preset range.This flow rate that has realized flowing into the material M of bitubular part 51 is controlled to be the flow rate that makes the material M that must be supplied to a part 20 and air be in adequate rate automatically.

Through material according to the invention feeding mechanism and the frozen-dessert making machine that uses this material feeding mechanism; As stated; The amount of material M in the material tank 10 is extracted gradually along with frozen confectionery S and is reduced; And when material liquid level L drops to when being lower than intercommunicating pore 51a, material M no longer is supplied to a part 20.Therefore, preferably, when liquid level L was above intercommunicating pore 51a, when being exposed in the air of liquid level L top such as bitubular part 51, the operator was to material tank 10 supplementary material M.In addition; When material tank 10 supplementary material M; Floating part 41 rises; And simultaneously, the performed opposite operation of operation when supply adjusting device 50 is carried out and descended with floating part 41, make intercommunicating pore 51a from the recovering state with large-size as shown in Figure 5 to the state with reduced size as shown in Figure 4.

In addition; Usually in such frozen-dessert making machine; Cooling segment can operate according to heat cycles (this heat cycles is the inverse process of kind of refrigeration cycle); Be used for coming heating material jar 10 and tube part 20 with uniform temperature, so that material M and frozen confectionery S are carried out hot pasteurize, this temperature can not cause going bad of material M.At this moment, for example, can the shielded-plate tube that the upper end has an outer back-up ring be inserted in the VERTICAL TUBE 61, to prevent the connection between VERTICAL TUBE 61 and the bitubular part 51.Carry out this shielding, thereby, can prevent that also the material M in the material tank 10 from flowing into a part 20 through intercommunicating pore 51a even in tube part 20, form the space with air because the frozen confectionery S of tube in the part 20 melts and be separated into material M.

The material feeding mechanism F1 with aforementioned structure through according to first embodiment can provide following advantage.

(effect 1-1)

The height of liquid level L through the material M in the floating part 41 detecting material jars 10, and the height of the linkage 155 liquid level L that combines to detect turns round.In addition, urceolus part 52 to regulate the size of intercommunicating pore 51a, is regulated the amount of the material M that is supplied to a part 20 with respect to inner cylindrical portion 53 rotations thus.Thereby can material M in the tube part 20 and the blending ratio between the air be adjusted in the preset range automatically, thereby can make the frozen confectionery of hope.

In addition, following advantage also is provided: need not keep watch on material M liquid level L height and be fed to operators' such as amount the complex operations of the material M of a part 20 through the valve manual adjustments according to the height of liquid level L.In addition, operate valve, the advantage that aspect health, makes moderate progress also is provided thus because the operator need not insert material tank 10 with his or her hand.

In addition, as shown in Figure 9, the size of intercommunicating pore is along with the liquid level L of the material M in the material tank 10 reduces and increases automatically and continuously, and this can stablize the flow rate of the material M that flows into bitubular part 51.This has prevented to be fed to the material M of a part 20 and the blending ratio between the air departs from preset range.In addition, in Fig. 9, describe for ease, represent the figure line of blending ratio to be designated as the straight line of representing constant ratio, undoubtedly, as long as this figure line drops in the preset range, this figure line can not be a straight line.

(effect 1-2)

In addition, liquid level detector is a floating part 41, and this floating part floats on the material liquid level L in the material tank 10, and can become original the manufacturing and do not make power device with lower with simple structure.

In addition; Supply adjusting device used herein is a kind of mechanism; This mechanism is used for the displacement of the floating part 41 of material tank 10 mechanically is delivered to bitubular part 52 through the displacement transfer device; So that urceolus part 52 is rotated with inner cylindrical portion 53 relative to each other, urceolus part 52 and inner cylindrical portion 53 are rotated relative to each other and do not use such as power sources such as motors.In other words, the supply adjusting device can be utilized along with the change of the height of the material liquid level L in the material tank 10 and the motion of the floating part 41 that moves constitutes as the mechanism of power source by a kind of.Therefore, the supply adjusting device can become original the manufacturing and not make power device with lower with simple structure.

(effect 1-3)

In addition, the displacement transfer device is a linkage 155, therefore can the displacement up or down of floating part 41 be converted reposefully into revolving force and natch it is delivered to urceolus part 52.

In addition, because VERTICAL TUBE 61 is inserted in the hole of floating part 41, therefore prevent floating part 41 free floating on material liquid level L, this can remain on the position that is positioned at the top of the second trunnion axis 156b basically just with the first trunnion axis 156a.Thereby the running of linkage 155 can make urceolus part 52 with the amount of high precision rotation corresponding to the displacement up or down of material liquid level L.

(effect 1-4)

Owing to use VERTICAL TUBE 61 as the air introducing device, therefore can provide independent device that air is introduced tube part 20, thereby simplify the structure of material feeding mechanism F1.

(effect 1-5)

Because intercommunicating pore 51a is arranged in the bottom of bitubular part 51,, also can stably material be fed to a part even the liquid level L of the material therefore in the material tank 10 drops near the bottom.

(the 3rd of first embodiment is revised embodiment)

Figure 12 is the view that the 3rd of expression first embodiment is revised embodiment.Figure 13 is the material feeding mechanism of embodiment is revised in expression according to the 3rd of first embodiment a side view.

Shown in figure 12, linkage can vertically be provided with a plurality of first paired trunnion axis 156a.Thus; Can select a pair of first trunnion axis 156a from a plurality of first paired trunnion axis 156a that are arranged in different vertical positions; And the first arm 157 can be connected to this on the first trunnion axis 156a by pivot; Shown in figure 13, this makes axis hole 157c (see figure 3) can change with respect to the height of floating part 41 and the setting angle between the first arm 157 in the linkage 155 and second arm 158.

As a result, for the height and position of identical floating part 41, the size of the intercommunicating pore in the bitubular part 51 can change with the position of the first selected trunnion axis 156a.For example, when the material M that here uses had higher viscosity, the countermeasure that can take was that the size that makes intercommunicating pore is slightly greater than the size when material M viscosity is low.In addition, under the said position of the first selected trunnion axis 156a, can change of the variation of the size of intercommunicating pore with respect to the slippage of floating part.

(the 4th of first embodiment is revised embodiment)

Only need have at the floating part 41 shown in Fig. 1, Fig. 2 etc. is enough to prevent that floating part 41 flatly breaks away from the hole of VERTICAL TUBE 61.Therefore, except annular, floating part 41 can be C shape, the shape of a hoof etc.And floating part 41 can be processed by the foam element such as foamed plastics.

In addition, float over the buoyancy that applied on the floating part 41 on the material liquid level L in the material tank 10 by the weight of floating part 41, amount or the like the decision of air in the floating part 41.Therefore, perhaps water is introduced the method for floating part main body 42 on floating part 41, can be provided with the aforementioned the 3rd and revise the identical effect of embodiment, promptly change the effect of the position of the first trunnion axis 156a with respect to material liquid level L through the buoyancy adjustment weight is installed.

(the 5th of first embodiment is revised embodiment)

axis hole

158c and 158d to the distance of axis hole 158e from the 3rd trunnion axis 156c to axis hole 157c.In this case, necessary is, when floating part 41 descends, is preventing floating part 41 when VERTICAL TUBE 61 is slided, and floating part 41 separates with VERTICAL TUBE 61.Therefore, floating part 41 need not have a part 42a and recessed portion 42b.

(second embodiment)

The similar part of second embodiment and first embodiment is; Material feeding mechanism in the frozen-dessert making machine comprises liquid level detector, supply adjusting device and air introducing device, but the difference of second embodiment and first embodiment is their structure.Hereinafter, will describe second embodiment, relate generally to difference with first embodiment.

Figure 14 is the key diagram of expression according to the material feeding mechanism F2 of second embodiment, and Figure 15 is the conceptual view that is used for explaining the following fact: descend if sell 85, then cause first through hole 81a rotation, thereby increase the size of intercommunicating pore 86 gradually.

In material feeding mechanism F2, liquid level detector is the floating part 241 of annular, and this floating part 241 floats on the liquid level of the frozen confectionery material in the material tank 10.Floating part 241 has smooth bottom and does not have as according to the recessed portion 42b (referring to Fig. 1 and Fig. 3) of the floating part 41 of first embodiment.

The supply adjusting device comprises bitubular part 80 and displacement transfer device, like Figure 14 and shown in Figure 15.

Bitubular part 80 is made up of urceolus part with first through hole 81a 81 and the inner cylindrical portion 82 with the second through hole 82a that can be communicated to the first through hole 81a, and wherein inner cylindrical portion 82 can be with respect to 81 rotations of urceolus part.Intercommunicating pore 86 is formed by the part that overlaps each other of the first through hole 81a and the second through hole 82a.

The displacement transfer device is delivered to bitubular part 80 so that urceolus part 81 is rotated with inner cylindrical portion 82 relative to each other with the displacement up or down of floating part 241, and this will change the size of aforementioned intercommunicating pore 86, therefore regulates the amount of the material that is fed to the tube part.

In addition, Figure 14 representes that urceolus part 81 has been drawn out the state of inner cylindrical portion 82, and wherein the material that is connected to the state of liquid sealing in the bottom of material tank 10 of the lower end of inner cylindrical portion 82 is introduced the path.

More specifically, urceolus part 81 is the VERTICAL TUBE that extend to its top from the bottom of material tank 10.Inner cylindrical portion 82 also is a VERTICAL TUBE; The lower end of this inner cylindrical portion 82 has the outward flange that will contact with the bottom of material tank 10; And below outward flange, also has recessed circumferential groove; So that assembling O shape ring in this circumferential groove, thereby, the material that is inserted in material tank 10 seals when introducing in the path.

Be assembled into bitubular part 80 in the urceolus part 81 through inner cylindrical portion 82 is inserted into, the top of this bitubular part 80 has the extraneous air intake, and vertically is installed in the material tank 10.In the bitubular part 80 in being installed in material tank 10, the extraneous air intake is communicated with through inner cylindrical portion 82 and is connected to tube inside partly, and therefore, bitubular part 80 is also as the air introducing device.

In addition; Displacement transfer device according to second embodiment is direction of motion switching mechanism, and this direction of motion switching mechanism will convert urceolus part 81 and inner cylindrical portion 82 rotatablely moving relative to each other according to the motion up or down of the floating part 241 of the height of material liquid level into.

Direction of motion switching mechanism comprises: the different directional slits that in each perisporium of urceolus part 81 and inner cylindrical portion 82, form; With the pin of being processed by metal or duroplasts 85, this pin 85 is installed on the floating part 241 and is inserted in each directional slit.

The directional slit that in urceolus part 81, forms is for example along the longitudinal guide slit of tube longitudinal extension and also as the aforementioned first through hole 81a.The directional slit 84 that in inner cylindrical portion 82, forms is spiral guiding slits and also as the aforementioned second through hole 82a for example.That is, the first through hole 81a and the second through hole 82a also have the function of the direction of motion of directing pin 85.

Form screwed hole in the mounting portion 87 through the L shaped parts on having the basal surface that is arranged in floating part 241, and be screwed to this screwed hole removably, can pin 85 be installed on the floating part 241 through having externally threaded pin 85.Thus, after bitubular part 80 is inserted in the hole of floating part 241, pin 85 can be installed on the mounting portion 87 and insert the first through hole 81a and the second through hole 82a so that assemble them.

In addition, like Figure 14 and shown in Figure 15, the second through hole 82a has the width that increases gradually along downward direction.Descend along the first through hole 81a and the second through hole 82a together along with the decline of floating part 241 if sell 85, this will make urceolus part 81 and inner cylindrical portion 82 rotate relative to each other.This will increase the size of the intercommunicating pore 86 that the lap by the first through hole 81a and the second through hole 82a constitutes gradually, wherein sell 85 and insert these laps.

In second embodiment, like Figure 14 and shown in Figure 15, inner cylindrical portion 82 is fixed on the material tank 10, and therefore, along with the decline of floating part 241, urceolus part 81 is with floating part 241 rotations of mount pin 85.Along with the rotation of urceolus part 81, the position of intercommunicating pore 86 descends, and the size of intercommunicating pore 86 also increases gradually.

So that describe, in having second embodiment of aforementioned structure, even the Level Change of material liquid level L, the material liquid level L from material tank 10 also remains on steady state value to the distance of the intercommunicating pore 86 of the position that is present in pin 85 with reference to figure 1, Figure 14 and Figure 15.Therefore, even the Level Change of material liquid level L, intercommunicating pore 86 also is present in from intercommunicating pore 86 and keeps constant position basically near the distance the material liquid level L.

When extracting frozen confectionery S according to the frozen-dessert making machine of second embodiment, the material M in the bitubular part 80 at first flows into the space in the part 20.Then, in the time of near the material liquid level L in the bitubular part 80 drops to intercommunicating pore 86, the material M in the material tank 10 begins to flow into bitubular part 80 through intercommunicating pore 86.When material was introduced material liquid level L in the path 11 and reached in the part 20, air also was supplied in the part 20, and material M and air are stirred in tube part 20 and cool off.Then, when accomplishing the extraction of frozen confectionery S, the liquid level L that continuously flows into the material M of bitubular part 80 rise to material tank 10 in the identical height of height of material liquid level L.

During this period; Decline along with the material liquid level L in the material tank 10; Pin 85 descends along spirality second through hole 82a and the first straight through hole 81a in rotation, and this has increased the size of intercommunicating pore 86 gradually, thereby increases the flow rate of the material M inflow bitubular part 80 in the material tank 10 gradually.

In second embodiment; Material liquid level L from material tank 10 changes to the distance of intercommunicating pore 86 hardly; Therefore, even during the Level Change of the material liquid level L in the material tank 10, the pressure that is applied on the intercommunicating pore 86 by the material M in the material tank 10 also remains essentially in steady state value.Yet the amount of the material M in the bitubular part 80 changes according to the height of the material liquid level L in the material tank 10.Therefore that is, extract frozen confectionery S and when the height of the material liquid level L in the material tank 10 descends, the amount that flows into the material M in the bitubular part 80 of tube part 20 reduces at every turn.
