Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a soft serve ice cream manufacturing machine, and more particularly to a device for detecting a sagging state peculiar to soft serve ice cream.

(b) The conventional Japanese Patent Publication No. 1987-7656 clearly describes the "sticky phenomenon" that occurs in soft-serve ice cream, and such invention
The present invention provides a technology that automatically prevents this sticky phenomenon, and the specific configuration for detecting the sticky phenomenon is a first timer device that operates continuously when the product supply of the unloading device is stopped. The timer device determines that the product is sticky when a predetermined period of time has continuously elapsed.

(/c) Problems to be Solved by the Invention In this prior art, when the set time is 3 hours as disclosed in the embodiment, when the soft serve ice cream is taken out from the takeout device slightly before the set time, the timer will be reset and start again from zero.This means that even if the business hours in a day are 10 hours, if the sample is taken out as described above, the sticky signal will never occur, and the sticky signal will not be accurate. There was a problem that the state could not be detected.

B) Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a switch that responds to the take-out operation of a take-out device, a timer circuit that outputs a wear-out signal when operated continuously for a predetermined period of time; a notification device that notifies the sagging state based on the sagging signal of the timer circuit; and a notification device that counts the number of ejections based on the ejection signal from the switch generated after the timer circuit starts;
A counter circuit is provided that generates an output when this reaches a predetermined number of times, and when the counter circuit outputs the fatigue signal before the timer circuit outputs the fatigue signal, the counter circuit is reset and the timer circuit is updated. This is a sagging detection device for a soft serve ice cream manufacturing machine.

(e) Effect In the above configuration, the timer circuit operates continuously unless an output is received from the counter circuit, and outputs a stagnation signal for operating the notification device after continuous operation for a predetermined period of time. On the other hand, if there is an output from the counter circuit before the tiredness signal is output from the timer circuit, the counter circuit is reset by this output and the timer circuit is updated, so that the tiredness signal is not output.

(11) is a mix supply device that appropriately supplies the mix mixed with air to the cooling cylinder (2), (Iz is the cooling cylinder (2)
Beater 1 (L dark I beater fi 6 drive motor, I is the soft serve ice cream take-out device attached to the front of the cooling cylinder (2) a cover (14B) forming a supply port (14A) that communicates with the inside of the cooling cylinder (2); a plunger (14C) that moves up and down inside the cover (14B) to open and close the supply port (14A);
) and an operation lever (14D) for raising and lowering the brush jar (14C). a-ha plunger (14C
) is a supply switch that closes when the soft serve ice cream that has risen is taken out, and (Le is a display LED serving as a notification device to notify that the soft serve ice cream has gone down).

FIG. 1 shows the stagnation detection circuit of the present invention (19 is the supply switch, αD is a timer circuit that starts when the cooling operation starts, T1 time (3 hours in the example) and Tt waiting time example 1 hour) operation is A input (17A
), when the A input (17A) is rLj, the operation is for time T1, and when the input (17A) is "H", the operation is for 17 hours.

α is a counter circuit that counts the number of times the soft serve ice cream is taken out, and it counts the predetermined number of clock pulses (10 times in the example) that are generated when the supply switch <1!19 is closed after the timer circuit (17) has started. When counted, an rHJ signal is output from the output terminal (18A). αS is an RS flip-flop.

Thus, the output terminal (17B) of the timer circuit (L7) is connected to the reset terminal (17C) of the timer circuit and the reset terminal (18B) of the counter circuit Cl8) via the diode (A), and also to the reset terminal (18B) of the counter circuit Cl8). ? P (L
Connected to 9 set input terminals (19 people). The output terminal (18A) of the counter circuit (18) is connected to the reset terminal (17C) of the timer circuit aη and the reset terminal (18B) of the counter circuit (18) via the diode Qυ, and is connected to the flip-flop α via the diode Qυ. It is connected to the value reset terminal (19B).The output terminal (19C) of the flip-flop (19) is connected to the timer circuit α.
It is connected to the A input (17A) of η and to the pace of the transistor example through a resistor. The LEDue is connected to the collector side of the transistor.

The cylinder is a heating switch, and when the switch (5) is closed and the cooling cylinder (2) is heated, the timer circuit (17) and counter circuit αa are connected via the diode 2.
and reset the flip-flop (19) through the diode.

Next, the operation will be explained based on the above configuration. First, when a cooling command is issued with an appropriate amount of mix supplied from the mix tank (1) to the cooling cylinder (2), the cooling pulp (5) opens, the electric compressor (3) operates, and the evaporation pipe ( The cold gas is circulated to the power and the cooling cylinder (2) is cooled to cool the mix supplied to the cylinder (2).The drive motor (IJ) is also operated to
2 stirs the mix in the cooling cylinder (2). Thus, the mix supplied to the cooling cylinder (2) gradually increases in viscosity and is finished as soft serve ice cream.

On the other hand, with the start of the cooling operation, the sag detection circuit of the present invention also starts its detection operation. In the initial state, the output of the 7-resop flop α9 is rLJ, so the eight power (17A) on the timer circuit side is rLJ, and the output of the timer circuit (17A) is rLJ.
) operates for time T1, the reset inputs of the timer circuit side and the counter circuit (18) are both rLJ, the timer circuit (17) starts, and the counter circuit αυ enters the state of receiving the clock.

Then, when the soft serve ice cream is taken out by the take-out device I after the timer circuit (17) is started, the supply switch C151 is closed, and the counter circuit α 1 is thereby closed.
Count the number of times one take out. When the number of extractions is counted a predetermined number of times, the output of the counter circuit α~ becomes rHJ, and at this time, if the predetermined time of the timer circuit Llη has not been reached, the output rHJ of the counter circuit end is passed through the diode Cυ to the timer circuit αD and the counter circuit (
With the IQ reset input as rHJ, the timer circuit αη
is updated and the counter circuit 0 is reset. That is, no fatigue signal is output from the timer circuit side.

In this way, the fact that the soft serve ice cream is taken out a predetermined number of times within T1 time means that the residence time of the soft serve ice cream in the cooling cylinder (2) is short, and the structure of the soft serve ice cream is removed by the beader (13). The soft serve ice cream does not go bad without being decomposed.Therefore, in this case, the above-mentioned detection operation is repeated.

On the other hand, if the timer circuit αη elapses T1 time before the counter circuit a mallet counts the predetermined number of extractions, the timer circuit (17) outputs the fatigue signal rHJ, and the set input of the flip-flop a9 is Let it be rHJ. As a result, the output of the flip-flop α9 becomes rHJ, turning on the transistor Q4, and the LED (16) lights up to indicate the failure.

In this way, if the soft-serve ice cream is not taken out a predetermined number of times after T1 time has elapsed, it means that the residence time of the soft-serve ice cream in the cooling cylinder (2) is long.
The structure of the soft serve ice cream is broken down by beads-nz, and the soft serve ice cream becomes stale.

Further, when the fatigue signal rHJ is output from the timer circuit α, the timer circuit αη and the counter circuit end are reset through the diode wire and operate from the beginning again. However, the one hour timer at this time is a flip-flop (
The output rHJ of L9 is connected to the A input (1) of the timer circuit (17).
7A) is received, the operation is switched to time T1. Therefore, from now on, unless there is an output from the counter circuit end, 12
The timer circuit αD and the counter circuit α barrel are reset repeatedly every time. Furthermore, if there is no output from the counter circuit α barrel, the reset input of the flip-flop through the diode @ holds "L", and the output of the flip-flop (19) holds rHJ. Therefore, the transistor (2) It continues to be turned on, and the LED (16) continues to light up.

In order to cancel the stale display, the soft serve ice cream must be taken out a predetermined number of times within 12 hours and the output of the counter circuit α to be set to "H". Timer circuit α
If the output is output from the counter circuit a before the output is output from η, the cylinder 7 Cl tube (1
The reset input of 9 becomes "H", and the flip-flop (
The output of 19 becomes rLJ.

Follow me, transistor c! 4) +-! , OF F L,
, L E D (Ie) turns off and cancels the fatigue display.

In this way, by taking out the soft-serve ice cream a predetermined number of times in a short 12 hours, the stale soft-serve ice cream staying in the cooling cylinder (2) is replaced with a large amount of fresh mix, and the soft-serve ice cream in the cooling cylinder (2) is replaced with a large amount of fresh mix. The sagging display is canceled because the organization of the product is improved. Then, the output of the counter circuit unit resets the timer circuit α and the kakuntar circuit α machiya, and the output rLJ of the flip-flop α9 causes the A input (17A) of the timer circuit αη to become “L”, causing the timer circuit unit to operate for T8 time. The switch returns to the initial state and the sag detection operation is performed again.

Another method for canceling the stagnation display is when the heating switch (c) is closed to heat the cooling cylinder (2). When the heating switch (c) closes, the reset input of the flip-flop (19) becomes "H" through the diode □□□, and the output of the flip-flop 9 becomes "L".
"become. Therefore, the transistor turns off and the L
EDC1l19 turns off and cancels the fatigue display. In addition, the timer circuit αη and the counter circuit σ are reset through the diode 2, so that they cease to function during the heating period. When the heating operation is completed and the heating switch (c) is opened, the cooling operation is restarted, and at the same time, the stagnation detection operation is performed again.

Through such heating and recooling operations, the stale soft serve ice cream is regenerated into a good soft serve serve.

Note that although the present invention uses an LED (le) as a notification device, other notification means such as a buzzer or voice may be used.

(g) Effects of the Invention As described above, the present invention has a counter circuit that counts how many times soft serve ice cream has been taken out during one predetermined period of time, and when the number of times that soft serve ice cream has been taken out does not reach a predetermined number of times, a timer circuit sends a stale signal. Since this is a sagging detection device that outputs and displays the sagging state of the soft-serve ice cream using an LED, it is not impossible to detect the sagging state even if the soft serve ice cream is sagging like in the past, and it is accurate. This system has an extremely excellent advantage of being able to detect and notify the sagging state of the soft serve ice cream in the cooling cylinder.
