JP 2006-190238 A

  Although not explicitly described in Patent Literature 1 described above, in the beverage supply device, the cleaning operation of each part is periodically performed, and also in the extractor, the cylinder is removed from the device main body and cleaned. Therefore, there is a possibility that the cleaning operator may forget to install the cylinder removed from the apparatus main body and cleaned at a predetermined position. If the cylinder is not provided, the crushed raw material and hot water will be scattered inside the apparatus body, which is not preferable.

  In order to prevent such forgetting to install the cylinder, it is conceivable to provide a dedicated sensor or the like for detecting the presence or absence of the installation of the cylinder. However, this is not preferable because it leads to an increase in manufacturing cost due to an increase in the number of parts.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a beverage supply device capable of satisfactorily determining the installation of a cylinder while suppressing an increase in manufacturing cost.

  In order to achieve the above object, a beverage supply device according to the present invention is an extractor that extracts a beverage by pulverized raw materials and hot water being charged, and a paper used when extracting the beverage with the extractor. A storage unit that rotatably supports and stores a filter roll that winds a filter, a rotation detection unit that detects rotation of the filter roll in the storage unit, and a cylinder and a filter block that constitute the extractor. And a paper roller unit that pulls out the paper filter from the filter roll when a feeding command is given when the paper filter is pulled out from the filter roll in a manner to pass through the gap. A beverage supply device for supplying a beverage to a container, the cylinder being close to the filter block at a predetermined timing. The paper filter is fed out by the paper roller unit while the extracting operation is performed by the extractor, and when the rotation detecting unit does not detect the rotation of the filter roll, it is determined that the installation of the cylinder is normal, while the rotation is determined. When the detection unit detects the rotation of the filter roll, the control unit determines that the installation of the cylinder is abnormal.

  Further, in the beverage supply device according to the present invention, when the control unit determines that the installation of the cylinder is abnormal, the control unit notifies the user of the abnormality.

  According to the present invention, the control means causes the paper roller unit to feed out the paper filter while causing the extractor to move the cylinder and the filter block close to each other at a predetermined timing, and the rotation detecting means detects the rotation of the filter roll. If not, it is determined that the installation of the cylinder is normal.On the other hand, if the rotation detection unit detects the rotation of the filter roll, it is determined that the installation of the cylinder is abnormal, so the rotation detection unit that detects the rotation of the filter roll is used. It is possible to determine whether or not the cylinder is installed, and it is not necessary to provide a dedicated sensor or the like for detecting whether or not the cylinder is installed. Therefore, there is an effect that the installation of the cylinder can be satisfactorily determined while suppressing an increase in manufacturing cost.

  The control unit 40 controls the operation of each unit of the beverage supply device 1 in accordance with programs and data stored in the storage unit 50.

  The control unit 40 may be realized, for example, by causing a processing device such as a CPU (Central Processing Unit) to execute a program, that is, by software, or by hardware such as an IC (Integrated Circuit). Alternatively, it may be realized by using software and hardware together.

  The control unit 40 includes a sales control unit 41, a supplyable number determination control unit 42, and a cylinder determination control unit 43. The sales control unit 41 controls the generation and supply of the beverage by the beverage generation unit 10. The suppliable number determination control unit 42 calculates the suppliable number until the storage box 20 becomes full, and performs a suppliable number determination process described later. The cylinder determination control unit 43 determines whether or not the installation of the cylinder 141 is normal, and performs a cylinder installation determination process described later.

  In the beverage supply device 1 having the above configuration, a coffee beverage can be supplied to the container C as follows. It is assumed that hot water at a predetermined temperature is generated and stored in hot water tank 131, and filter block 142 is moving upward in a manner close to cylinder 141.

  When the display section 30 is touch-operated by the user, the sales control section 41 of the control section 40 to which the sales signal has been given gives a drive command to the raw material supply driving section 11a and outputs the amount of coffee beans corresponding to the sales signal.

The amount of coffee beans paid out from the raw material box 11 by driving the raw material supply driving unit 11a is stored in the storage unit 50 by the sales control unit 41. Further, the sales control unit 41 gives a drive command to the hot water supply pump 132 to cause a predetermined amount of hot water corresponding to the sales signal to be poured into the extractor 14 from the hot water tank 131.

  In the extractor 14, a coffee beverage is extracted from hot water and ground coffee beans, and the extracted coffee beverage is supplied to a nozzle 17 via a beverage supply line 16, and is placed on the bend stage S from the nozzle 17. The coffee beverage is supplied to the container C by discharging the coffee beverage to the container C.

  Thereafter, the sales control unit 41 moves the filter block 142 downward in a manner away from the cylinder 141, gives an operation command to the paper roller unit 22, causes the paper filter PF to pay out a predetermined amount, and extracts the coffee beverage. The generated extraction residue is stored in the storage box 20 together with the paper filter PF.

  When such a coffee beverage is supplied, the supply possible number determination control unit 42 of the control unit 40 performs the following supply possible number determination processing.

  FIG. 3 is a flowchart showing the process of the suppliable number determination process performed by the suppliable number determination control unit 42 shown in FIG.

  In the suppliable number determination process, the suppliable number determination control unit 42 calculates an integrated value of the payout amounts stored in the storage unit 50 (step S101). The suppliable number determination control unit 42 that has calculated the integrated value of the payout amount reads the upper limit predetermined from the storage unit 50 assuming that the storage box 20 is full (step S102), and determines the suppliable number. It is calculated (step S103).

  The calculation of the supplyable number in step S103 will be described. The suppliable number determination control unit 42 obtains a subtraction value by subtracting the integrated value calculated in step S101 from the read upper limit value, and divides the subtraction value by the usage amount of the maximum consumption beverage to determine the supply possible number. calculate.

  The suppliable number determination control unit 42 having calculated the suppliable number in this way sends a display command of the suppliable number to the display unit 30 (step S104), and thereafter returns the procedure to end the current process. .

  According to this, the number of drinks that can be supplied until the storage box 20 becomes full is displayed on the display unit 30. Therefore, the worker such as an employee of the store can remove the extracted residue until the number of drinks that can be supplied becomes zero. There is no need to perform collection work.

  By the way, in the beverage supply device 1, a cleaning operation and a rinsing operation for distributing only hot water to the beverage generating unit 10 are performed according to a predetermined time schedule. Then, when a sales signal is given after the cleaning operation or when the rinsing operation is performed, the cylinder determination control unit 43 of the control unit 40 performs the following cylinder operation before the supply of the beverage and the rinsing operation described above. Perform the installation determination process.

  FIG. 4 is a flowchart showing the processing contents of the cylinder installation determination processing performed by the cylinder determination control unit 43 shown in FIG.

  In the cylinder installation determination process, the cylinder determination control unit 43 sends a proximity command to the motor 142 a of the filter block 142 to move the filter block 142 upward in a manner to approach the cylinder 141, and the paper roller unit 22. Is transmitted (steps S201 and S202), and an input of a rotation signal from the rotation detection unit 151 is waited for (step S203).

  When the rotation signal is not input from the rotation detection unit 151 even after the predetermined time has elapsed (step S203: No), the cylinder determination control unit 43 places the paper filter PF between the cylinder 141 and the filter block 142. As a result, it is determined that the filter roll FR does not rotate, the installation of the cylinder 141 is determined to be normal (step S204), an operation stop command is sent to the paper roller unit 22, and the filter block 142 is sent to the motor 142a of the filter block 142. Is transmitted (step S205, step S206), and the procedure is returned to end the current processing.

  On the other hand, when the rotation signal is input from the rotation detection unit 151 (Step S203: Yes), the cylinder determination control unit 43 determines that the installation of the cylinder 141 is abnormal (Step S207), and indicates that an abnormality has occurred. Is displayed on the display unit 30 (step S208). Then, the cylinder determination control unit 43 sends an operation stop command to the paper roller unit 22 and sends a separation command to the motor 142a of the filter block 142 to move the filter block 142 downward (step S209). (Step S210) Then, the procedure is returned to end the current processing.

  As described above, according to the beverage supply device 1 according to the embodiment of the present invention, the control unit 40 integrates the amount of the raw material dispensed in the raw material box 11 to obtain an integrated value, and the storage box 20 is fully filled. The available number of drinks is calculated by dividing the subtracted value obtained by subtracting the integrated value from the predetermined upper limit value by the amount of use of the maximum amount of beverage, and displaying the number of available supplies on the display unit 30. , It is not necessary for the worker such as an employee of the store to perform the work of collecting the extracted slag until the supply number becomes zero, and prompts the work of collecting the extracted slag after the storage box 20 is full. As a result, it is possible to reduce the work of collecting the extraction slag.

  According to the beverage supply device 1 described above, the control unit 40 causes the paper roller unit 22 to feed out the paper filter PF while causing the extractor 14 to move the cylinder 141 and the filter block 142 closer to each other at a predetermined timing, and rotate the paper filter PF. If the detection unit 151 does not detect the rotation of the filter roll FR, it is determined that the installation of the cylinder 141 is normal, while if the rotation detection unit 151 detects the rotation of the filter roll FR, it is determined that the installation of the cylinder 141 is abnormal. Therefore, the presence or absence of the installation of the cylinder 141 can be determined using the existing rotation detection unit 151, and there is no need to provide a dedicated sensor or the like for detecting the presence or absence of the installation of the cylinder 141. Therefore, the installation of the cylinder 141 can be determined satisfactorily while suppressing an increase in manufacturing cost.

  Although the preferred embodiment of the present invention has been described above, the present invention is not limited to this, and various changes can be made.

  In the above-described embodiment, the control unit 40 calculates the supplyable number by dividing the subtraction value obtained by subtracting the integrated value from the upper limit value by the usage amount of the maximum consumption beverage, In the present invention, the supply amount may be calculated by dividing the subtraction value by the consumption amount of the beverage having the smallest amount of the raw material used per supply, or the subtraction value may be calculated per supply. The suppliable number may be calculated by dividing by the average value of the raw material usage. That is, in the present invention, the number of drinks that can be supplied may be calculated until the integrated value obtained by integrating the dispensed amounts of the raw materials in the raw material box 11 reaches the predetermined upper limit assuming that the storage box 20 is full. .

  In the above-described embodiment, in the cylinder installation determination process, when it is determined that the installation of the cylinder 141 is abnormal, the fact that an abnormality has occurred is displayed on the display unit 30. If it is determined that the installation is abnormal, an alarm such as a buzzer sound may be output by the notification unit to urge the worker such as an employee of the store to re-install the cylinder.

  In the above-described embodiment, the motor 142a of the filter block 142 is driven to move the filter block 142 up and down so as to approach and separate from the cylinder 141. However, in the present invention, the cylinder holding the cylinder The holding unit may move the cylinder in the vertical direction such that the cylinder approaches and separates from the filter block.
