However, in the method of operating the mixer disclosed in Patent Document 1, as can be confirmed from the automatic operation flow charts of FIGS. Alternatively, whole eggs and granulated sugar are prepared in advance, and no additional materials are added during operation.

In that case, the vertical mixer itself disclosed in Patent Document 1 is used for whipping (whipping), stirring (beating), and mixing (mixing) for fresh cream, sponge dough, cake dough, and other viscous materials. ), etc., but the addition of additional materials during operation is actually done manually by the operator.

The necessary amount of the additional material is measured in advance, and the operator puts the weighed additional material into the food dough storage container of the mixer without interrupting the operation of the mixer. As a result, the efficiency of making various fabrics is very low, and it is easy to miss the timing of adding additional materials.

The object of the present invention is to solve such problems. To the peripheral part of a food mixer equipped with a material storage container, a stirrer that revolves while rotating inside the material storage container, and an electric heater for the material storage container,

By rotating the motor for driving the screw conveyor in the powder/granule material feeder, the necessary powder/granule additional mixed material to be charged is strained out into the material storage container of the food mixer. While cutting and transporting

By opening the automatic cutout valve for opening and closing the flow pipe in the liquid/viscous material feeder, the necessary liquid/viscous material to be added is cut out and put into the material storage container of the food mixer. as much as possible, and

The load cell provided in the powder/granule material feeder functions as a subtraction weighing scale to detect that the predetermined target input amount of the necessary powder/granule additional mixed material to be charged has been reached. Based on the output signal, the rotation of the screw conveyor drive motor is stopped to stop cutting and conveying the additional mixed material to the material storage container of the food mixer,

Output of detecting that the load cell provided in the liquid/viscous material charging machine has reached a preset target charging amount of the necessary additional mixed material of the liquid/viscous material to be charged as a subtraction weighing scale. Based on the signal, the automatic cut-out valve for opening and closing the flow pipe is closed, thereby automatically controlling to stop cutting out and charging the additional mixed material into the material storage container of the food mixer.

Materials necessary for making various kinds of dough are stored in advance, and additional mixed materials to be put into the material storage container during operation of the mixer are stored in the material input machine, respectively, and Western confectionery is prepared by operating the food mixer. In creating the target dough, in addition to the stirring power and heating power that are the operation process data for each dough, the necessary numerical values such as the target heating temperature, the target conductivity, and the target timer operation time are specified above. By setting and inputting to the control panel (sequencer) by touch operation of the input switch part on the operation panel for automatic operation of the food mixer, the necessary additional mixed material to be put into the above material storage container during the operation of the mixer can be automatically and mechanically fed from each material feeder with good timing, instead of manual work. All kinds of fabrics can be obtained fully automatically and efficiently.

In addition, since the powder/granule material feeder consisting of the screw feeder of the above configuration is adopted, the necessary powder/granule additional mixed material is transferred from the material feeder to the material storage container of the food mixer at the timing. In addition, it is possible to quickly cut out and convey wheat flour and other powder materials to the material storage container while surely straining them naturally so that so-called lumps do not occur.

Measurement and detection are performed, and based on the detection output signal, a specified amount of material is put into the material storage container (T), and the stirring power and heating power are automatically stopped.

The stirring mechanism (A) revolves around the center main shaft (60) rotationally driven by the geared motor (48) in the same direction (F) as the center main shaft (60) and at the same time moves in the opposite direction to the revolving motion. It is provided with first and second eccentric stirring shafts (61) and (62) that automatically operate in the direction (R) and the same direction (F) respectively, and the pair of first and second eccentric stirring shafts (61) (62) The first and second stirrers (P1) and (P2) are detachably connected to the lower ends of the. The first and second stirrers (P1) and (P2) will be described later.

That is, as is clear from FIGS. 6 and 8 to 11 showing details of the stirring mechanism (A), the horizontal fixed base (45) crossing the upper space in the stirring box (Ab) has A geared motor (48) for driving the stirring mechanism (A) is mounted from above through a motor mounting plate (47) and a plurality of pedestals (46). A fixing case (64) for a radial bearing (63) that rotatably supports a center main shaft (60) that hangs down from a geared motor (48) is inserted into the part from the reverse downward direction. (65) is a thrust bearing that separately supports the center main shaft (60).

(66) is a large-diameter circular gear-supporting ceiling that is firmly attached to the lower surface of the fixing base (45) and the body surface of the fixed bearing case (64) by welding with a plurality of fixing bolts (67). It is a plate, and an internal gear (internal gear) (68) is attached to the lower surface of the peripheral portion of the ceiling plate (66) by a plurality of fixing bolts (69).

(71) is a fixing nut for retaining the rotating bowl (70), which is screwed and fastened to the lower end of the center main shaft (60).

The pair of the first and second eccentric stirring shafts (61) and (62) both hang down toward the eccentric portion in the material storage container (T), and the first eccentric stirring shaft (61) is The other second eccentric stirring shaft (62) is also at a long distance from the center main shaft (60), while being parallel to the main main shaft (60) with a short distance (L1) (for example, about 83.75 mm). Radial bearings (72) (73) in the first and second bearing cases (70c) (70d) provided at corresponding positions of the rotary bowl (70), in a parallel state maintaining a distance (L2) (for example, about 115 mm) ) are rotatably (rotatably) supported.

In addition, a relatively large diameter first pinion gear (74), which is inscribed in the internal gear (68) on the side of the gear supporting ceiling plate (66) in the fixed installation state and can mesh and rotate with it, is provided with the first pinion gear (74). 1 It is fitted and integrated with the upper end of the eccentric stirring shaft (61) via a key, spline, or the like.

Furthermore, an idle gear (intermediate gear) (75), which is inscribed in the internal gear (68) on the side of the gear-supporting ceiling plate (66) and can rotate in mesh with it, is arranged parallel to the center main shaft (60).

(77) is also fitted and integrated with the upper end of the second eccentric stirring shaft (62).

Moreover, the idle gear (75) has approximately the same diameter as the first pinion gear (74), but the second pinion gear (77) is sized smaller in diameter than the first pinion gear (74). The relationship is set so that the second eccentric stirring shaft (62) rotates (rotates) faster than (61). (78) is a radial bearing interposed between the idle gear (75) and its support shaft (76); ) is attached to the eccentric part in a locking state.

In this regard, in the illustrated embodiment, the first eccentric stirring shaft (61) rotates at about 4 times the revolution speed, and the second eccentric stirring shaft (62) rotates at about 6 times the revolution speed. However, this rotation gear ratio can be freely changed and adjusted according to the type of dough in the pastry and the purpose of its processing and action (mixing, beating, whipping, etc.). be able to.

Therefore, when the center main shaft (60) of the stirring mechanism (A) is rotationally driven in the direction of the arrow (F) in FIG. The first and second eccentric stirring shafts (61) (62) and the idle gear support shaft (76) slowly revolve around the center main shaft (60) in the same direction (F).

Simultaneously with the orbital motion, the first eccentric stirring shaft (61) rotates in engagement with the first pinion gear (74) at its upper end and the internal gear (68), and the direction (F) in which the orbital motion is performed. while the second eccentric stirring shaft (62) engages and rotates between the second pinion gear (77) at its upper end and the idle gear (75) and the idle gear Through meshing rotation between (75) and the internal gear (68), the direction (F) opposite to the direction (R) in which the first eccentric stirring shaft (61) rotates (same as the direction in which it revolves) ), and rotate faster than the rotation (rotation) speed of the first eccentric stirring shaft (61).

In that case, the center main shaft (60) and the pair of first and second eccentric stirring shafts (61) and (62) are driven by the geared motor (48) as the rotational drive source in the direction of the arrow (F) in FIG. ), but the second eccentric stirring shaft (62) rotating through the idle gear (75) and the second pinion gear (77 ) is inserted into the fitting surface of the one-way clutch (80). Due to the sliding action of the one-way clutch (80), the transmission from the second pinion gear (77) to the second eccentric stirring shaft (62) is cut off, and the second eccentric stirring shaft (62) is automatically stopped. there is

The lower ends of the first and second eccentric stirring shafts (61) and (62) in the stirring mechanism (A) are notched as interlocking hooks (81) as shown in FIGS. (82) is a connection sleeve inserted into the eccentric stirring shafts (61) and (62) from below, and (83) is a retainer attached to the connection sleeve (82) via a fixing bolt (84). It is a piece that engages with the lifting guide groove rails (85) arranged in rows on the circumferential surfaces of the eccentric stirring shafts (61) and (62), and falls off the eccentric stirring shafts (61) and (62). It is designed not to.

Further, (86) is a cover plate that blinds the rotating bowl opening (not shown) of the upper bottom plate (44) of the stirring action box (Ab), and is attached to the periphery of the rotating bowl opening. A large-diameter ring-shaped rotating guide rail (87) surrounding the surrounding cover (70b) of the rotary bowl (70) is attached to the lower surface of the rotary bowl (70) by a plurality of fixing bolts (88). It is

The rotation guide rail (87) has a substantially U-shaped cross section, and a separate synthetic resin hanger hook (89) is engaged in the recessed circumferential groove. The hanger hook (89) has an arc shape that is curved by about 240 degrees in plan view, and a plurality of horizontal locking pins (90) are planted on it.

(91) is an opening/closing cover formed by bending a stainless steel plate in an arc shape at the same angle as the hanger hook (89), and has a handle (92), and a plurality of hanging plate pieces (93) of the handle (92). It is detachably locked to the locking pin (90) of the hanger hook (89).

In addition, (94) is a rear cover that is closed in a circular shape (360 degrees) in a plan view together with the opening/closing cover (91), and is also curved from the stainless steel plate by the remaining approximately 120 degrees.
A mounting stay (95), which forms a curved arc shape and integrally protrudes rearward from it, is integrally attached to the front surface of the lower space of the agitating box (Ab) with a fixing bolt (96) as shown in FIG. ing.

Therefore, an operator grips the handle (92) of the opening/closing cover (91), and manually rotates the opening/closing cover (91) along the rotation guide rail (87) to thereby rotate the container receiving arm (11). The open top surface of the material container (T), which is received and suspended in the container (T), can be closed into a generally circular (360 degree) enclosure with its rear cover (94).

However, in that case, as shown in FIGS. 8 and 12, the open upper surface of the material storage container (T) is surrounded by a circle (360 degrees) in a plan view together with its rear cover (94) in a normally closed state. From the suspension plate piece (93) of the opening/closing cover (91) in the above, the detection piece (97) of the metal material is integrally projected laterally, and the detection piece (97) can be detected. A proximity sensor (98) is mounted and fixed at a corresponding position on the upper bottom plate (44) of the agitation action box (Ab) or its rotary bowl escape inlet cover plate (86).

Based on the output electric signal of the proximity sensor (98) detected from the piece (97) to be detected when the opening/closing cover (91) closes the open upper surface of the material storage container (T) in a normal enveloping state. , the geared motor (48), which is the drive source of the stirring mechanism (A), is rotated, otherwise the geared motor (48) is automatically controlled so as not to start rotating. The proximity sensor (98) can function as a power switch for the stirring mechanism (A).

Needless to say, by appropriately rotating the opening/closing cover (91) to open it, various pastry doughs and their ingredients can be taken in and out of the ingredient storage container (T) without any trouble.

It has already been explained that the rotary bowl (70), which rotatably (rotates) the first and second eccentric stirring shafts (61) and (62), rotates integrally with the central main shaft (60) of the stirring mechanism (A). However, from the eccentric part of the horizontal disk (70a) in the rotating bowl (70), the sensor holder (100) as shown in FIGS. 13 and 14 hangs integrally.

(101) is a receiving ring provided at the lower end of the sensor holder (100). While slowly orbiting together with a pair of 1, 2 eccentric stirring shafts (61) (62), the conductivity and temperature of the dough during whipping in the material storage container (T) are detected in real time ( Measure.

Then, when a timer (not shown) detects that the 3 minutes in the fifth step has expired, the control panel (54) of the food mixer that has received the detection output signal switches to the next sixth step. In the step (quantitative egg feeding step), the automatic air valve (air valve) (146) for opening and closing the flow pipe of the third material feeder (K3) is opened, and the whole eggs in the hopper (144) are discharged into the flow pipe (145). ) into the material storage container (T) of the food mixer so that it naturally flows down.

Then, when the temperature sensor (116) of the wireless transmitter (S) detects that the target heating temperature of 106° C. in the third step has been reached, the control of the food mixer that received the detection output signal is performed. The board (54) rotates the screw conveyor drive motor (129) of the second material feeder (K2) in the next fourth step (quantitative sugar feeding step) to convey the sugar in the hopper (130). By doing so, the material is automatically put into the material storage container (T) of the food mixer.

The amount of sugar input to the material storage container (T) is measured (detected) by the load cell (subtractive weight scale) (127) of the second material input machine (K2), and a preset input amount (for example 1.2 kg) is detected by the load cell (127), the control panel (54) receiving the detection output signal stops the rotation of the screw conveyor drive motor (129).

When the above set amount of sugar is added, in the next step 5 (timer operation step), heating is not performed, and only stirring at 30% stirring power is performed for 1 minute. (illustration omitted), the control panel (54) of the food mixer receives the detection output signal, and the screw By rotating the conveyor drive motor (129), the wheat flour in the hopper (130) is conveyed while being strained, and automatically put into the material storage container (T) of the food mixer.

The amount of flour input to the material storage container (T) is measured by the load cell (127) of the first material input machine (K1), and it is detected that the preset input amount (for example, 0.5 kg) has been reached. As soon as this is done, the rotation of the screw conveyor drive motor (129) is controlled to stop by the control panel (54).

After the set amount of flour has been added, in the seventh step (timer operation step), as in the fifth step, stirring is performed for one minute at a stirring power of 30% without heating.

When one minute has passed, the control panel (54), which has received the detection output signal of the timer (not shown), in the subsequent eighth step (quantitative feeding step of egg white), the fourth ingredient feeder (K4). An automatic valve (air valve) (146) for opening and closing the flow pipe is opened so that the egg white in the hopper (144) naturally flows down from the flow pipe (145) to the material storage container (T) of the food mixer. throw into.

The amount of egg white input to the material storage container (T) is measured by the load cell (142) of the fourth material input machine (K4), and it is detected that the preset input amount (eg, 1.2 kg) has been reached. Then, the control panel (54), which receives the detection output signal from the load cell (142), closes the automatic opening/closing valve (146) for opening and closing the flow pipe (145), and stops feeding the egg white. .

When the set amount of egg white is added, in the final step 9 (timer operation step), similarly to the 5th and 7th steps, no heating is performed, and only stirring at a stirring power of 30% is performed for 1 minute, The operation is terminated when the time is up.

It is automatically controlled to put into the material storage container (T) of the mixer, and in the 5th, 7th and 9th steps (all are timer operation steps), the timer detects that the target operation time has expired. Based on this, in the 6th, 8th, and 10th steps (each of which is a quantitative egg charging step), a preset amount of whole eggs is added from a separate third material charging machine (K3) to the food mixer's material storage container (T ) is automatically controlled.

In the example of making the financier in FIG. 27, the temperature detection sensor (116) of the wireless transmitter (S) detects the target heating temperature of the dough in the third step (target temperature designation operation step). Based on the output signal, In the next fourth step (quantitative sugar charging step), a preset amount of sugar to be charged from another second material charging device (K2) is automatically controlled to be charged into the material storage container (T) of the food mixer. Also, in the fifth step (timer operation step), based on the output signal that the timer has detected that the target operation time has expired, in the following sixth step (powder quantitative addition step), the first material charging machine (K1) It is automatically controlled so that a preset amount of wheat flour to be put into the food mixer is put into the material storage container (T) of the food mixer. Furthermore, in the seventh step (timer operation step), based on the output signal that the timer has detected that the target operation time has expired, in the next eighth step (egg white quantitative addition step), another fourth material charging machine (K4 ) is automatically controlled to feed a preset amount of egg white into the material storage container (T) of the food mixer.
