Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic beverage stirring method and an automatic beverage stirring device, and particularly to an automatic beverage stirring method that can automatically stir a beverage safely and uniformly. and its equipment.

[Conventional technology]

In recent years, bumpers have been developed to meet the diversification of tastes.

BACKGROUND ART Light restaurants such as gar shops are increasingly selling shakes and the like that are served after stirring the ingredients.

Shake beverages lose their flavor if left for a long time, so they are usually not made in advance, but are made according to the number of orders received from customers.

Traditionally, the method for making shakes is to put various ingredients into a cup-shaped container, have a store employee hold the container, and use the hanging stirring blades of a mixer rotating in a fixed position to raise and lower the container from below. At the same time, the raw materials in the container are being stirred.

[Problem to be solved by the invention]

However, with the conventional beverage stirring method, in which the store clerk holds the container and raises and lowers it from the bottom of the mixer's stirring blades,
Since the container is lifted and lowered by hand against the exposed rotating stirring blade, there is a risk that the rotating stirring blade may come into contact with the thin container wall, which is extremely dangerous. In addition, the amount of operation for raising and lowering the container and the stirring time vary, resulting in problems such as over-shaking causing the shake to jump out of the container, and under-shaking resulting in an unsatisfactory flavor.

The shake flying out of the container can be prevented to some extent by covering the top opening of the container with a lid that has a relatively small opening on the top surface through which a stirring blade can be inserted. However, in this case, since the lid makes it difficult to see the inside of the container, variations in the amount of operation for raising and lowering the container are more likely to occur, and variations in the degree of shake production become even more noticeable.

[Means to solve the problem]

In order to solve the above-mentioned problems, the automatic beverage stirring method and device according to the present invention are capable of automatically stirring a beverage contained in a container, and are capable of safely and uniformly stirring this beverage. The object of the present invention is to provide a method and apparatus for achieving this.

That is, in the automatic beverage stirring method of claim 1, raw materials are placed in a container having an opening through which a vertical stirring blade placed at a fixed position can be inserted, and this container is positioned at a container attachment/detachment position below the stirring blade. During the preparatory stage of loading the container holder, the lifting drive device, which is started by giving a start command, moves the container and container holder from the container attachment/detachment position to the position where the stirring blade is at a predetermined depth within the container. a lifting stage in which the container and the container holder that have reached the top dead center are folded back and returned to the container attachment/detachment position by a lifting drive device;
It is characterized in that the raw material in the container is automatically stirred through a stirring stage in which a stirring blade is driven by a stirring drive device during a predetermined period of the lifting stage.

Further, in the automatic beverage stirring method of claim 2, in the automatic beverage stirring method, the lifting step includes closing an energization holding switch provided in the power supply circuit of the lifting drive device by giving a start command. a start command stage in which the lift drive device is maintained in operation by keeping the energization hold switch open for a predetermined short period of time after the start of the lift stage; After the container holding part moves to a predetermined lifting control position, the lifting drive switch connected in parallel with the energization holding switch is closed until the container holding part turns around at top dead center and descends to the lifting control position. and a termination stage in which the lifting drive switch is opened (thereby terminating the lifting stage) when the lowering container holder has been lowered to the lifting control position.
The above-mentioned stirring stage is started by closing the stirring drive switch inserted in the power supply circuit of the stirring drive device when the rising container holder moves to the elevation control position or a higher stirring control position. and then, when the container holding part turns back at the top dead center and descends to a stirring control position higher than the above-mentioned elevation control position, the stirring drive switch is opened to end the operation. There is. Further, the automatic beverage stirring device according to claim 3 includes a stirring blade having a vertical axis arranged at a fixed position, a stirring drive motor for rotationally driving the stirring blade, and an opening through which the stirring blade can be inserted. a container holding part that supports a container and is movable up and down between a container attachment/detachment position where the container is located below a stirring blade and a top dead center where the stirring blade is located at a predetermined depth within the container; It is equipped with a lifting drive motor for driving the container holder up and down, and a control circuit for controlling the stirring drive motor and the lifting drive motor, and the control circuit is interposed in the power supply circuit of the lifting drive motor and connected to the start switch. An energization holding switch that closes the power supply circuit for a predetermined short period of time upon a starting operation, and an energization holding switch that is connected to the power supply circuit of the lifting drive motor in parallel with the energization holding switch, and the container is positioned above a predetermined lifting control position. a lift drive switch that is closed when the lift is in the lower position and opened when the lift is in a lower position;
Interposed in the power supply circuit of the stirring drive motor, it is closed when the container placed is at the above-mentioned lifting control position or a higher stirring control position, and is closed when the container is placed at a position lower than the stirring control position higher than the lifting control position. It is characterized by being equipped with an agitation drive switch that is opened when the device is in the position.

The shape of the container used in the present invention is not particularly limited as long as it has an opening through which a stirring blade can be inserted.
The container may be formed into a cup shape, or may consist of a cup-shaped container body and a lid that covers the top opening of the container body and has an opening on the top surface through which a stirring blade can be inserted. You can. By using a container with such a lid, it is possible to prevent raw materials, etc. that rise along the inner peripheral surface of the container body due to centrifugal force during stirring from scattering around.

Further, the container holding portion may be configured to prevent the container from falling and rolling, for example, the tapered outer circumferential surface of the container, the lower surface of the outer flange formed at the upper end of the container, A structure of a container holding part consisting of a container mounting having a locking part such as a through hole, a U-shaped groove, or a bottomed hole for receiving a stepped surface formed in the middle of the outer circumferential surface of the container from below; The structure of a container holding part is composed of a container holder and a rocking device that prevents the container from swaying above or below the container holder; A structure of a container holder consisting of a container holder that simply receives and holds a container from below and a container presser that presses the container downward is used.

In the case where the container holding section is composed of only a container placement, the container placement prevents the container from falling and rolling, and the container is stabilized by the weight of the container and the raw material in the container.

When the container holder consists of a container holder and a rocking device,
The container is prevented from falling by the container mounting, and the container is prevented from rolling by the container mounting and the rocker.

In addition, when the container holding part is composed of a container holder and a container presser, the container can be prevented from falling by the container holder, and the container can be prevented from rolling by holding the container between the container holder and the container holder. This is prevented by

When the container holder is composed of a container placement and a rocking device or a container holding device, the rocking device or container holding device becomes effective at the end of the preparatory stage, that is, when loading of containers is completed. This is not necessary, and it is sufficient that the action of the seeding stopper or the container holding device is started after the lifting stage starts and the container placement starts to rise, but before the stirring stage starts. Therefore, for example, the rocking stop may be constructed of a plate material curved to form a semi-cylindrical surface or a U-shaped surface having approximately the same height as the lifting stroke of the container, or the rocker may be positioned at a position that is in contact with the outline of the lifting space of the container. It is made up of a plurality of wires or rods arranged vertically in the vertical direction and has a length approximately the same as the lifting stroke of the container, and this rocking device is placed above the container loaded on the container mounting position located at the container attachment/detachment position. It can be fixed in place.

However, when the container holding part is composed of a container holder and a container holder, when loading a container, a space is formed between the container holder and the container holder to allow a small portion of the container to pass through. On the other hand, before the stirring stage starts, the space is narrowed and the container is held between the container holder and the container holder, and the container holder is moved up and down along with the container placement while the container is still being held. There is a need to.

For this purpose, for example, an elevating drive device may be constituted by a placement elevating drive device that drives the container placement up and down and a presser elevating drive device that drives the container presser up and down, but the mechanical configuration and control In order to simplify the method, the container holder is driven up and down by a lift drive device, and a restraining device is provided to limit the descending range of the container holder, so that the container holder is positioned at a predetermined height or higher from the bottom dead center. In some cases, the container holding device is configured to be stopped by a container placed on a container mount, and when the container mount is lowered below a predetermined height, the container holding device is stopped by a restraining device, It is possible to configure the container holder and the container holder to be attracted to each other by means of attracting means such as a spring or a magnet.

The elevating drive device may be configured to be able to move the container holder up and down within a predetermined stroke. Therefore, the actuator used in the elevating drive device may be an electric motor or the like that rotates in one direction or in both forward and reverse directions. It may be a rotary drive machine (or a linear drive machine such as a cylinder).

If the actuator of the lifting drive device is a rotary drive machine, a mechanism is required to convert the rotational movement of the actuator into lifting movement. A mechanism for changing the direction of movement is, for example, an eccentric pin linked to the output shaft of the actuator, one end of which is swingably connected to the eccentric pin, and the other end of which swings to the container holder. It is possible to employ a slider-crank mechanism having a connecting member that can be connected together and a guide means for guiding the container holder up and down. The cam mechanism includes an eccentric pin interlocked with the output shaft of the actuator, a horizontal cam groove in which the eccentric pin is slidably fitted and fixed to the container holding part, and a guide means for guiding the container holding part up and down. It is also possible to adopt Furthermore, it is also possible to employ a cam mechanism having an eccentric cam interlocked with the output shaft of the actuator, a cam follower fixed to the container holder, and a guide means for guiding the container holder up and down. Furthermore, a drive sprocket interlocked with the output shaft of the actuator, an idler disposed above or below the drive sprocket, an endless chain wrapped around the drive sprocket and the idler, and a bin fixed at one point of the endless chain. It is also possible to employ a chain transmission mechanism having a horizontal cam groove into which the bottle is slidably fitted and fixed to the container holder, and a guide means for guiding the container holder up and down.

When using a reversible rotary drive machine, a rack and pinion mechanism consisting of a pinion that is linked to the output shaft of the actuator and a rank that is linked to the container holder, a drive sprocket that is linked to the output shaft of the actuator, and a A chain transmission mechanism consisting of an idler placed below, an endless chain wrapped around the drive sprocket and the idler, and a bottle fixed to one point of the endless chain and fixed to the container holder, and an actuator. A screw/nut mechanism, etc., consisting of a threaded rod that rotates in conjunction with the threaded rod and a nand that appears to be able to be screwed forward and backward into the threaded rod and is interlocked and connected to the container holding part, is used as a mechanism that converts rotation into vertical motion. It is possible to use it.

If the actuator of the lifting drive device is a linear drive machine, it is also possible to link the container holding part directly to the output part of the actuator via a bracket, etc., and it is also possible to connect a chain or steel belt between the actuator and the container holding part. ,
It is also possible to interlock them via a transmission means such as a link rond.

In the automatic beverage stirring method of the present invention, the lifting and lowering steps include:
For example, it is started by a start command consisting of an electric signal given by a user or by a detection means for detecting that a container containing raw materials is loaded into the container holder from the outside.

When a user gives a starting command, for example, a push button switch that can output a starting command with one touch operation,
A momentary type snap switch or the like may be provided. When the detection means for detecting that a container is loaded into the container holder issues a start command, for example, a switch circuit that is turned on in response to the weight of the container and raw materials loaded in the container holder; It is sufficient to include a command signal output circuit including a one-shot pulse output circuit that outputs a one-shot pulse as a starting command when this switch is turned on.

As a method of controlling the elevating drive means after inputting the starting command, various methods corresponding to the actuators of the elevating drive device can be adopted.

For example, if the actuator of the lifting drive device is configured with a motor that rotates in one direction, it will start when a start command is input, and the container holder will rise to top dead center and then return to the container attachment/detaching position. A timer is provided for setting the required time as a set time, and a lift control switch is provided that is switched to close the power supply circuit of the motor in response to a start command and switched to open the power supply circuit when the set time of the timer elapses, A method may be adopted in which the elevating drive device is continuously operated from the start command until the container holding portion rises to the top dead center and returns to the container attachment/detachment position.

In this case, the above-mentioned lifting/lowering stage may be divided into, for example, a starting command stage in which a starting command is given to close an energization holding switch installed in the power supply circuit of the lifting drive device to start the lifting/lowering stage, and a lifting/lowering stage. A transient stage in which the operation of the lifting drive device is maintained by keeping the energization holding switch closed for a predetermined short period of time after the start of A driving stage in which the lifting drive switch connected in parallel with the energization holding switch is closed to maintain the operation of the lifting drive device after the container holding part turns back at top dead center and descends to the lifting control position. and a termination step in which the raising/lowering step is ended by opening the raising/lowering drive switch when the lowering container holder has descended to the raising/lowering control position. Here, the energization holding switch is configured with a simple push button switch, and the user can, for example,
．． The pushbutton switch may be kept pressed for a required period of about 5 seconds, or the energization holding switch that can be turned on with a one-touch operation may be a self-holding relay switch or a timer relay switch.

If a linear drive device such as a motor or cylinder that rotates in both forward and reverse directions is used as the actuator of the lifting drive, in addition to the above configurations, a switch or It is detected by a detection means such as a sensor, or it is determined that the container holding part has risen to the top dead center due to time-up of a timer, and at the time of detection or judgment, the rotation direction of the motor or the driving direction of the linear drive machine is reversed by the reversing means. A procedure is required to do so.

In the automatic beverage stirring method of the present invention, the timing of the start and end of the stirring stage is arbitrary as long as the stirring blade is inserted into the raw material in the container during that time and the time required to sufficiently stir the raw material is secured. Can be set.

As a method for setting the timing of the start or end of the stirring stage, for example, when the container placed in the rising position moves to the lift control position or a higher stirring control position, the power supply circuit of the stirring drive device is set. The process is started by closing the agitation drive switch installed. After that, when the container mounting table turns around at the top dead center and returns to the stirring control position higher than the lifting position, the stirring drive switch is opened. Alternatively, when the lifting drive device is started, the container is held A method of using one or two timers whose starting point is when the top dead center of the unit is reached, and starting or ending the stirring stage when the set time of the timer has elapsed from the starting point, or an elevator drive. A method of detecting the amount of movement of a device or container holding part, integrating the amount of movement based on an electrical signal corresponding to the amount of movement, and starting or ending the stirring stage when the accumulated amount reaches a predetermined reference value. Alternatively, a method is adopted in which the usage of driving sources such as electric power and flow rate of working fluid supplied to the lifting drive device is integrated, and the stirring stage is started or ended when the integrated amount reaches a predetermined reference value. can do.

The stirring drive device may be configured to rotate the stirring blade in one direction or in both forward and reverse directions, and the actuator thereof is not limited to a rotary drive machine, but a linear drive machine can also be used.

When using a linear drive machine, a mechanism is required to convert the linear motion into rotational motion. It is possible to use an inverted mechanism. However, in order to omit such a mechanism and simplify the configuration of the stirring drive and the control method for the stirring drive, it is advantageous to use a rotary drive that rotates in one direction.

Various energy sources such as electricity, hydraulic pressure, and pneumatic pressure can be used as the driving source for the lifting drive device and stirring drive device, but commercial power sources that are usually installed in light restaurants such as hamburger shops can be used. Using the supplied electricity as the drive source is advantageous in terms of ease of handling and simplification of the configuration of the lifting drive device and the stirring drive device.

Finally, the lift drive switch or stirring drive switch of the present invention is not particularly limited as long as it is switched on and off when the container holding part or the lift drive device passes a specific position. It is possible to use mechanical contact switches such as switches and seesaw switches, non-contact switches such as proximity switches, non-contact switches such as electromagnetic sensors and photo switches, and also compares slideac resistors with standard resistances. It is also possible to use a switch circuit with a circuit, a timer switch, etc.

[For production]

According to the present invention, by loading a container into the container holder and giving a manual or automatic start command, the container is automatically moved from the container attachment/detachment position below the stirring blade to a predetermined depth within the container. It is raised to the top dead center located at the top dead center, then turned back at the top dead center and returned to the container loading/unloading position.The stirring blade is rotated for a predetermined period during the raising and lowering, so that the raw materials placed in the container are automatically is stirred.

Then, the container and the container holding part are raised by the lifting drive device from the container attachment/detachment position to the top dead center where the stirring blade is located at a predetermined depth within the container, so that the container is raised and lowered with respect to the stirring blade. In addition, since the stirring blade is driven by the stirring drive device over a predetermined period of time to raise the container and the container holder from the container mounting/dismounting position and return to the container mounting/dismounting position by folding back at the top dead center, the stirring time becomes constant. It becomes constant.

As a result, the degree of agitation of the raw materials can be made uniform, and it is possible to prevent the raw materials from scattering around due to over-shaking and the loss of flavor due to insufficient shaking. Further, according to the present invention, the user holds the container by hand only in the preparation stage of loading the container into the container holder and when removing the container from the container holder after stirring is completed,
It is safe because there is no need to touch the container during stirring. Furthermore, during the above-mentioned stirring, there is almost no need for store staff to be involved in such stirring work, so they can do it in one hand while carrying out other tasks.

2 is narrowed and the mold presser 1 is attached to the fitting part 10b.
The second receiver is stopped, and after this time, the mold presser 12 is lifted from the restraint vi, 24 by the container holder 11 via the container 6, and rises while maintaining a constant distance from the container holder 11.

For example, when the upper surface of the raw material in the container 6 is lifted to the vicinity of the lower surface of the agitator 1 and the container 6 and the container holding part 7 reach the stirring control position, the operation input part 38d of the stirring drive switch 38 is activated from the switch driving part 40. Away, movable contact 38
a comes into contact with the fixed contact 38c. As a result, the movable contact 37c of the relay switch 37 changes from the fixed contact 37c to the fixed contact 37c.
d, the stirring drive motor 8 is started and the stirring stage begins. At the same time, the power to the second opening/closing part 29°C of the energization hold switch 29 is stopped, so the relay coil 29a is turned off, and the energization hold switch 29 is turned off.
The first opening/closing operation section 29b of is also opened. Furthermore, a relay coil 32b for setting the latching relay 32
is turned on, and the opening/closing operation section 32c is latched in the closed state.

In the stirring stage, the container 6 is further raised while rotating the agitator 1, and after the agitator 1 stirs to the bottom inside the container 6, the container 6 turns back at the top dead center and descends to a position lower than the stirring control position. The operation input section 38d of the stirring drive switch 38 is pressed by the switch drive section 40,
The movable contact 38a is switched to a position where it contacts the fixed contact 38b. As a result, the movable contact 37c of the relay switch 37 is switched to a position where it contacts the fixed contact 37e, the power supply circuit 34 of the stirring drive motor 8 is opened, the stirring stage is completed, and the buzzer 47 starts sounding.

Further, the container 6 and the container holding part 7 are lowered, but the mold presser 1
2 is restrained by the restraining device 24 to the position before starting to rise, and only the container 6 and the container holding part 7 are further lowered.

Eventually, when the container 6 and the container holder 7 descend to the elevation control position, the operation input section 31d of the elevation drive switch 31 is pressed by the switch drive section 40, and the movable contact 31a is switched to a position where it contacts the fixed contact 31c. . As a result, the power supply circuit 30 of the lifting drive motor 15 is opened.
Power to the lifting drive motor 15 is stopped, the reset relay coil 32a is energized, the opening/closing part 32c of the latching relay 32 is opened, and the buzzer 47 is stopped from sounding. After the power supply to the lifting drive motor 15 is stopped, the container 6 and the container holding part 7 move by inertia to the container attachment/detachment position and stop, thereby completing the lifting stage.

According to this embodiment, the container 6 is loaded into the container holding part 7,
By manually giving a start command, the container 6 is automatically raised from the container attachment/detachment position 7 below the agitator 1 to the top dead center where the agitator 1 is located at a predetermined depth within the container 6, and then further raised. The agitator 1 is turned back at the dead center and returned to the container attachment/detachment position, and the agitator 1 is rotated for a predetermined period during the ascent and descent, so that the raw material placed in the container 6 is automatically stirred. Then, the container 6 and the container holding part 7 are raised from the container attachment/detachment position to the top dead center where the agitator 1 is located at a predetermined depth inside the container 6 by the lifting drive device 5. The agitator 1 is driven by the agitation drive motor 8 over a predetermined period in which the lifting stroke is constant, and the container 6 and the container holding part 7 are raised from the container attachment/detachment position, turned back at the top dead center, and returned to the container attachment/detachment position. Since it is driven, the stirring time is constant.

As a result, the degree of stirring of the raw materials can be made uniform, and it is possible to prevent the raw materials from scattering around due to over-shaking, and from spoiling the flavor due to insufficient shaking. Furthermore, the user holds the container 6 by hand during the preparatory stage of loading the container 6 into the container holder 7 and after the stirring is completed.
This is done only when taking out the liquid from the container holding part 7, and there is no need to touch the container during stirring, so it is safe.

After this, the user can take out the container 6 from the container holder 7.

In the above embodiment, the agitator 1 as the stirring blade is
Although the agitator 1 is configured to be driven by the agitation drive motor 8 as an agitation drive device in the agitation stage, the agitator 1 may be driven in synchronization with the container holder 7 and the like.

Furthermore, it is desirable that the agitation end timing in the agitator 1 be set at a position where the container holder 7 is higher than the elevation control position. As a result, the driving of the agitator 1 is stopped when the container holding part 7 is on the way down, and the driving of the agitator 1 is stopped before the agitator 1 is removed from the inside of the container 6. It is possible to prevent the shaken beverage or the like adhering to the agitator 1 from scattering to the outside of the container 6, which tends to occur due to the agitator 1 rotating even after being removed from the container.
