[0046] Embodiments of the present application will be described with reference to the accompanying drawings.

[0047] <1. Coffee bean grinding device>

[0048] The coffee bean grinding device 1 will be described with reference to Figure 1 Figure 1 is a perspective view of the coffee bean grinding device 1. The coffee bean grinding device 1 includes a storage device 4, a pulverizing device 5, and a control device 11 (not shown in the drawing) that controls them. Further, as shown in Figure 1 , an information display device 12 is provided at a hopper 40 of the storage device 4. This information display device 12 is connected to the control device 11, and is a touch panel type display for various controls of the coffee bean grinding device 1, and in addition to displaying various information, can also accept input from a manager, a demander of a beverage. Figure 1

[0049] <1-1. Storage device>

[0050] ​​The storage device 4 includes a hopper 40 for accommodating the roasted coffee beans. Further, one hopper 40 is provided in the present embodiment, but a structure in which a plurality of hoppers 40 are provided can also be adopted. In addition, in the case where a plurality of hoppers 40 are provided, roasted coffee beans of different kinds and roasting degrees can be separately accommodated. The hopper 40 is provided with a delivery mechanism (not shown) for delivering the roasted coffee beans to the downstream side, and the roasted coffee beans are supplied to the pulverizing device 5 by the delivery mechanism.

[0051] <1-2. Pulverizing device>

[0052] The pulverizing device 5 will be described with reference to FIGS. 1 and 2. Figure 1 and Figure 2 The pulverizing device 5 will be described with reference to FIGS. 1 and 2. Figure 2 is a longitudinal sectional view of the pulverizing device 5. The pulverizing device 5 includes a grinder 5A, a grinder 5B, and a separation device 6. The grinder 5A and the grinder 5B are mechanisms that grind the roasted coffee beans supplied from the storage device 4. The grinder 5A is a grinder for breaking the coffee beans to a certain degree (for example, about 1 / 4) so as to easily separate the impurities adhering to the coffee beans. In addition, the grinder 5B is a grinder for making the coffee beans in the state broken by the grinder 5A to a desired particle size of coffee ground beans. Therefore, the particle sizes at which the coffee beans are ground by these grinders 5A and 5B are different, and the grinder 5B is a finer grinder than the grinder 5A. Further, the particle size of the ground beans in the grinder 5B sometimes has an error (about ±5 μm), but can be adjusted by adjusting the interval between the rotating blade 58b and the fixed blade 57b.

[0053] <1-2-1. Grinder>

[0054] The grinder 5A includes a motor 52a and a main body 53a. The motor 52a is a driving source of the grinder 5A. The main body 53a is a unit that accommodates the blades, and the rotating shaft 54a is built in the main body 53a. The gear 55a is provided to the rotating shaft 54a, and the driving force of the motor 52a is transmitted to the rotating shaft 54a via the gear 55a.

[0055] The rotating blade 58a as a blade is provided to the rotating shaft 54a. In addition, the fixed blade 57a as a blade is provided around the rotating blade 58a. The inside of the main body 53a communicates with the inlet 50a and the outlet 51a. The roasted coffee beans supplied from the storage device 4 enter the main body 53a from the inlet 50a formed in the side of the main body 53a, are sandwiched between the rotating blade 58a and the fixed blade 57a, and are pulverized. The suppression plate 56a is provided to the position of the rotating shaft 54a on the upper side than the rotating blade 58a, and the suppression plate 56a suppresses the roasted coffee beans from escaping to the upper side. In the grinder 5A, the roasted coffee beans are pulverized to, for example, about 1 / 4. The ground beans after the pulverization are discharged from the outlet 51a to the separation device 6.

[0056] Further, the roast coffee beans supplied to the supply inlet 50a can also be supplied not from above the rotary blade 58a but to a height that will come into contact with the side surface. In this case, since the escape of the roast coffee beans upward is suppressed by the rotary blade 58a, the suppression plate 56a can also not be provided.

[0057] The grinder 5A can change the size of the roast coffee beans discharged after being pulverized by changing the rotation speed of the rotary blade 58a. Alternatively, the size of the roast coffee beans can also be changed by manually adjusting the distance between the rotary blade 58a and the fixed blade 57a.

[0058] The separation device 6 is a mechanism for separating impurities from the ground beans. The separation device 6 is disposed between the grinder 5A and the grinder 5B. That is, in the case of the present embodiment, the roast coffee beans supplied from the storage device 4 are first coarsely ground by the grinder 5A, and impurities are separated from the coarsely ground beans by the separation device 6. The coarsely ground beans from which the impurities have been separated are finely ground by the grinder 5B. The impurities separated by the separation device 6 are represented by silver skin and fine particles. These impurities sometimes deteriorate the taste of coffee beverages. The separation device 6 is a mechanism for separating impurities by the suction force of air, the details of which will be described later.

[0059] The grinder 5B includes a motor 52b and a main body 53b. The motor 52b is a driving source of the grinder 5B. The main body 53b is a unit that houses the blades, and the main body 53b has a rotary shaft 54b built therein. A belt wheel 55b is provided to the rotary shaft 54b, and the driving force of the motor 52b is transmitted to the rotary shaft 54b via a belt 59b and the belt wheel 55b.

[0060] A rotary blade 58b is further provided to the rotary shaft 54b, and a fixed blade 57b is provided to the upper side of the rotary blade 58b. The inside of the main body 53b communicates with a supply inlet 50b and a discharge outlet 51b. The ground beans that fall from the separation device 6 enter the main body 53b from the supply inlet 50b, are pinched between the rotary blade 58b and the fixed blade 57b, and are further pulverized. The ground beans that have been pulverized into a powder are discharged from the discharge outlet 51b. Further, the particle size of the ground beans in the grinder 5B can be adjusted by adjusting the interval between the rotary blade 58b and the fixed blade 57b.

[0061] The pulverization of the roast coffee beans can also be performed by one grinder (one-stage pulverization). However, by being configured to be performed in two stages by the two grinders 5A and 5B as in the present embodiment, it is easy to make the particle size of the ground beans uniform, and it is possible to make the extraction degree of the coffee liquid constant. When the beans are pulverized, heat is sometimes generated due to the friction of the blades against the beans. By being configured to be pulverized in two stages, it is also possible to suppress the heat generation due to the friction at the time of pulverization, and to prevent the deterioration (such as the reduction in flavor) of the ground beans.

[0062] In addition, by having the stages of rough grinding → separation of impurities → fine grinding, when separating the silver skin and the like, the quality difference between the impurities and the ground beans (desired parts) can be made large. In this way, the separation efficiency of the impurities can be improved, and the ground beans (desired parts) can be prevented from being separated as impurities. In addition, the separation treatment of the impurities using suction by air is interposed between the rough grinding and the fine grinding, and thus the heating of the ground beans can be suppressed using air cooling. Thus, the deterioration (for example, flavor reduction) of the ground beans can also be prevented.

[0063] <1-2-2. Separation device>

[0064] Next, the separation device 6 will be described with reference to Figures 1-3 Figure 3 is a partial cross-sectional perspective view of the separation device 6. The separation device 6 includes a suction unit 6A and a formation unit 6B. The formation unit 6B is a hollow body that forms a separation chamber SC through which the ground beans that have fallen freely from the grinder 5A pass. The suction unit 6A is a unit that communicates with the separation chamber SC in a direction (in the case of the present embodiment, the left-right direction) that intersects the passing direction of the ground beans (in the case of the present embodiment, the up-down direction) and suctions the air in the separation chamber SC. By suctioning the air in the separation chamber SC, light objects such as silver skins and fine particles can be suctioned. Thus, the impurities can be separated from the ground beans.

[0065] The suction unit 6A is a mechanism of the centrifugal separation type. The suction unit 6A includes a blowing unit 60A and a recovery container 60B. In the case of the present embodiment, the blowing unit 60A is a fan motor that discharges the air in the recovery container 60B upward.

[0066] The recovery container 60B includes an upper portion 61 and a lower portion 62 that are engaged in a separable manner. The lower portion 62 is a bottomed cylindrical type that is open upward and forms a space for accumulating impurities. The upper portion 61 constitutes a lid portion that is fitted to the opening of the lower portion 62. The upper portion 61 includes a cylindrical outer peripheral wall 61a and an exhaust cylinder 61b that is coaxial with the outer peripheral wall 61a. The blowing unit 60A is fixed to the upper portion 61 above the exhaust cylinder 61b so as to suction the air in the exhaust cylinder 61b. The upper portion 61 also includes a cylindrical connection portion 61c that is provided extending in the radial direction. The connection portion 61c is connected to the formation unit 6B so as to communicate the separation chamber SC with the recovery container 60B. The connection portion 61c is open to the side of the exhaust cylinder 61b.

[0067] By driving the blowing unit 60A, air is suctioned from the separation chamber SC through the connection portion 61c and the exhaust cylinder 61b, and is discharged upward through the blowing unit 60A. Thus, the air in the separation chamber SC is suctioned, and the impurities are separated from the ground beans. Figure 3 ​The air flow is indicated by arrows dl to d3. By this air flow, the air containing the impurities is drawn from the separation chamber SC into the recovery container 60B through the connection portion 61c. Since the connection portion 61c opens to the side of the exhaust cylinder 61b, the air containing the impurities revolves around the exhaust cylinder 61b. The impurities D in the air fall down due to their weight, and concentrate in a portion of the recovery container 60B (piled on the bottom surface of the lower portion 62). The air is exhausted upward through the inside of the exhaust cylinder 61b.

[0068] A plurality of fins 61d are formed integrally with the peripheral surface of the exhaust cylinder 61b. The plurality of fins 61d are arranged in the peripheral direction of the exhaust cylinder 61b. Each of the fins 61d is inclined obliquely with respect to the axial direction of the exhaust cylinder 61b. By providing such fins 61, the revolving of the air containing the impurities D around the exhaust cylinder 61b is promoted. In addition, the separation of the impurities D is promoted by the fins 61. As a result, it is possible to suppress the length in the up-and-down direction of the suction unit 6A, and contribute to the downsizing of the device.

[0069] In addition, in the present embodiment, the forming unit 6B is arranged on the falling path of the ground coffee ground by the grinder 5A and the grinder 5B, and on the other hand, the suction unit 6A of the centrifugal separation type is arranged to the side of the falling path. The mechanism of the centrifugal separation type tends to be long in the up-and-down direction, but by arranging the suction unit 6A to the side in a manner that is offset from the falling path, it is possible to arrange the suction unit 6A in parallel with the grinder 5A and the grinder 5B in the lateral direction. This contributes to the suppression of the length in the up-and-down direction of the device. In particular, in the case where two-stage pulverization is performed by the grinder 5A and the grinder 5B as in the present embodiment, there is a tendency for the length in the up-and-down direction of the device to be long, and therefore such arrangement of the suction unit 6A is effective for the downsizing of the device.

[0070] The forming unit 6B will be described with reference to Figures 1-6 Figure 4 is a longitudinal sectional view of the forming unit 6B. Figure 5 is a perspective view and a partially enlarged view of the forming unit 6B. Figure 6 is a plan view of the forming unit 6B, and is a comparative explanatory view of the cross-sectional area.

[0071] In the case of the present embodiment, the forming unit 6B is formed by joining two members that are divided in half in the up-and-down direction. The forming unit 6B includes a tube portion 63 and a separation chamber forming portion 64, and has a scoop shape in plan view. The tube portion 63 is a cylinder that forms a communication path 63a with the suction unit 6A, and is provided extending in the lateral direction (a direction that intersects the center line CL described later). The separation chamber forming portion 64 is connected to the tube portion 63, and is a hollow body of a circular ring shape that opens in the up-and-down direction at the center, which forms the separation chamber SC.

[0072] ​In the present embodiment, when separating the impurities from the ground coffee, a method of attracting the impurities by applying a lateral air pressure to the ground coffee falling from the grinder 5A is adopted. This is advantageous in that the length in the vertical direction can be shortened as compared with the centrifugal separation method.

[0073] The separation chamber forming portion 64 includes a cylindrical portion 65 provided so as to extend in the vertical direction. The cylindrical portion 65 protrudes into the separation chamber SC from a central portion thereof in the vertical direction to a lower portion. The cylindrical portion 65 has an opening portion 65a at one end thereof on the upper side, and the opening portion 65a forms a drop inlet for the ground coffee that communicates with the separation chamber SC. The opening portion 65a is located outside the separation chamber SC and is connected to the discharge port 51a of the grinder 5A. Thus, the ground coffee falling from the discharge port 51a is introduced into the separation chamber forming portion 64 without omission. The cylindrical portion 65 has an opening portion 65b at the other end thereof on the lower side. The opening portion 65b is located inside the separation chamber SC. Since the opening portion 65b faces the separation chamber SC, the ground coffee falling from the discharge port 51a is introduced into the separation chamber SC without omission.

[0074] In the case of the present embodiment, the cylindrical portion 65 has a circular cylindrical shape, and the opening portion 65a and the opening portion 65b have circular shapes that are concentric with respect to the center line CL. Thus, the ground coffee falling from the discharge port 51a easily passes through the cylindrical portion 65. The cylindrical portion 65 has a tapered shape in which the cross-sectional area of the internal space gradually decreases from the opening portion 65a side toward the opening portion 65b side. Since the inner wall of the cylindrical portion 65 has a mortar shape, the falling ground coffee easily collides with the inner wall. The ground coffee falling from the grinder 5A sometimes falls in a state in which the coffee beans are stuck together in a lump. When the ground coffee is in the state of a lump, the separation efficiency of the impurities sometimes decreases. In the case of the present embodiment, the ground coffee in a lump collides with the inner wall of the cylindrical portion 65, whereby the lump can be broken, and the impurities can be easily separated.

[0075] Further, in terms of breaking the lump of the ground coffee, the inner wall of the cylindrical portion 65 is not limited to a mortar shape. As long as there is a portion in which the cross-sectional area of the internal space is smaller than the opening portion 65a at an intermediate position of the cylindrical portion 65, and there is an inner wall that is inclined (non-horizontal) with respect to the center line CL, collision with the lump can be promoted, and the ground coffee can be smoothly caused to fall. In addition, the cylindrical portion 65 can not necessarily protrude into the separation chamber SC, but can have only a portion that protrudes upward from the outer surface of the separation chamber forming portion 64. However, by causing the cylindrical portion 65 to protrude into the separation chamber SC, the wind speed around the cylindrical portion 65 can be increased. Thus, the separation effect of the impurities by the air pressure in the region R1 that is relatively far from the pipe portion 63 can be improved.

[0076] The separation chamber forming section 64 has a discharge port 66 communicating with the separation chamber SC for discharging the ground beans after impurities have been separated. In this embodiment, the discharge port 66 is located below the opening 65b, and the ground beans, after passing through the cylindrical section 65, pass through the separation chamber SC and fall freely from the discharge port 66. In this embodiment, the discharge port 66 is a circular opening located on the center line CL, and is an opening concentric with the openings 65a and 65b. Therefore, the ground beans can easily pass through the separation chamber forming section 64 by falling freely, preventing the ground beans from accumulating inside the separation chamber forming section 64.

[0077] like Figure 6 As shown, in this embodiment, the cross-sectional area SC2 of the outlet 66 is larger than the cross-sectional area SC1 of the opening 65b. In this embodiment, when viewed from the vertical direction, the opening 65b and the outlet 66 overlap. Therefore, when the opening 65b is projected onto the outlet 66 in the vertical direction, the opening 65b converges to the inside of the outlet 66. In other words, the opening 65b converges within the region formed by extending the outlet 66 in the vertical direction. It is also possible to employ a structure in which the opening 65b and the outlet 66 are not on the same center line but overlap, or a structure in which at least one is not circular but overlaps.

[0078] The ratio of the cross-sectional area SC1 to the cross-sectional area SC2 is, for example, 95% or less or 85% or less, and, in addition, for example, 60% or more or 70% or more. Since the opening portion 65b and the discharge port 66 are concentric circles, they overlap each other when viewed in the center line CL direction. Therefore, the ground coffee that freely falls from the opening portion 65b is easily discharged from the discharge port 66. In addition, it is possible to prevent the fallen ground coffee from bouncing to the tube portion 63 side by colliding with the edge of the discharge port 66, and it is also possible to suppress the desired ground coffee from being attracted by the attraction unit 6A. It is exemplified that the opening area of the one-end opening portion (for example, 65a) is smaller than the opening area of the discharge port (for example, 66), but the opening area of the discharge port (for example, 66) and the opening area of the one-end opening portion (for example, 65a) can be the same, and the opening area of the one-end opening portion (for example, 65a) can be larger than the opening area of the discharge port (for example, 66). It is exemplified that the opening area of the other-end opening portion (for example, 65b) is smaller than the opening area of the discharge port (for example, 66), but the opening area of the discharge port (for example, 66) and the opening area of the other-end opening portion (for example, 65b) can be the same, and the opening area of the other-end opening portion (for example, 65b) can be larger than the opening area of the discharge port (for example, 66). It is exemplified that air is sucked from the discharge port 66 and the inlet port (for example, 65a, 65a') by the attraction unit (for example, 6A), but the amount of air sucked from the discharge port 66 can be larger than the amount of air sucked from the inlet port (for example, 65a, 65a'). This can be achieved by the other-end opening portion (for example, 65b) protruding into the separation chamber, the size of the cross-sectional area of the discharge port 66 being larger than the size of the opening area of the one-end opening portion (for example, 65a), the size of the cross-sectional area of the discharge port 66 being larger than the size of the opening area of the other-end opening portion (for example, 65b), the distance from the discharge port 66 to the separation chamber being closer than the distance from the one-end opening portion (for example, 65a) to the separation chamber, the distance from the discharge port 66 to the exhaust cylinder 61b being closer than the distance from the one-end opening portion (for example, 65a) to the exhaust cylinder 61b, or the distance from the discharge port 66 to the air supply unit 60A being closer than the distance from the one-end opening portion (for example, 65a) to the air supply unit 60A. With respect to any one of the inner wall portions of the members (63 to 65) that constitute the forming unit 6B and the separation chamber SC, the tubular portion 65, and the other-end opening portion (for example, 65b), it is possible to be configured to directly contact or indirectly contact via other members the grinder (at least one of 5A and 5B) to transmit the vibration generated by the rotation of the grinder, thereby vibrating.For example, in the case of the coffee bean grinding device 1 in the embodiment, since they directly or indirectly contact, in the operation of the grinder, any one of the inner wall portions of the members (63 to 65) constituting the forming unit 6B, the separation chamber SC, the cylindrical portion 65, the other end opening portion (e.g., 65b) vibrates, and the light impurities that have entered the separation chamber SC from the other end opening portion (e.g., 65b) are subjected to braking by the turbulent air generated in the separation chamber SC by the vibration, so that the impurities are easily attracted by the attraction unit (e.g., 6A). In particular, as in the coffee bean grinding device 1 in the embodiment, the forming unit 6B directly contacts the grinder 5A and the grinder 5A among the grinders 5A and 5B, and the forming unit 6B is subjected to moderate vibration by directly contacting one of the grinders, so that the light impurities are easily attracted.

[0079] In the case of the present embodiment, the air attracted by the attraction unit 6A is mainly attracted from the discharge port 66. Therefore, a gap is provided between the discharge port 66 and the throw-in port 50b of the grinder 5B to promote the attraction of air. The arrow d4 schematically indicates the direction of the air flow of the air attracted by the attraction unit 6A. By attracting the air from the discharge port 66, the impurities are less likely to be discharged from the discharge port 66, and the separation performance of the ground beans and the impurities can be improved. In addition, the air attracted by the attraction unit 6A is also attracted from the opening portion 65a.

[0080] A turbulent flow promoting portion 67 is formed in the peripheral wall that demarcates the discharge port 66. The turbulent flow promoting portion 67 causes the air attracted from the discharge port 66 toward the separation chamber SC to generate turbulent flow. By forming the turbulent flow promoting portion 67, turbulent flow is easily generated in the region R2, in particular, between the opening portion 65b and the discharge port 66. In addition, in the case of the present embodiment, the peripheral wind speed is increased in the cylindrical portion 65, so that the generation of turbulent flow at the region R2 can be promoted complementarily.

[0081] The ground beans thrown into the throw-in port 65a are stirred by the influence of the turbulent flow when passing through the region R2. In the case of the present embodiment, in particular, since the cross-sectional area SC2 of the discharge port 66 is larger than the cross-sectional area SCI of the opening portion 65b as described above, the ground beans necessarily pass through the region R2. Due to the turbulent flow, the impurities such as silver skins and fine particles are easily separated from the ground beans. Thus, even if the separation chamber SC is a small space, the separation efficiency of the impurities can be improved, and it is particularly effective to reduce the length of the separation chamber SC in the vertical direction, which is advantageous for the downsizing of the device in the case of two-stage pulverization by the grinders 5A and 5B as in the present embodiment.

[0082] In the case of the present embodiment, the turbulence promoting portion 67 includes a plurality of turbulence promoting elements 67a. The turbulence promoting element 67a is a protrusion that protrudes downward in the up-down direction. The protruding direction of the turbulence promoting element 67a can be an arbitrary direction, but in terms of making it easier to generate turbulence in the separation chamber SC, a direction ranging from the downward direction to the radially inward direction is preferable. If the protruding direction is the downward direction as in the present embodiment, it is more preferable because the ground coffee that falls down does not get caught.

[0083] The cross-sectional shape of the turbulence promoting element 67a is a shape in which a trapezoidal-shaped quadrangular prism is disposed with the upper base of the cross section facing the center line CL direction, and a chamfer 67b is implemented on the inner side of the tip end portion. The shape of the turbulence promoting element 67a is not limited to the shape of the present embodiment, and it is preferable to make the shape of the discharge port 66 a complex shape in three dimensions.

[0084] In the case of the present embodiment, the turbulence promoting elements 67a are repeatedly formed in the surrounding direction d5 of the discharge port 66. Thereby, air is blown into the region R from a plurality of directions to promote the generation of turbulence. The pitch of adjacent turbulence promoting elements 67a is different, but in the present embodiment, it is equidistant. In addition, 12 are formed, but the number of turbulence promoting elements 67a is arbitrary.

[0085] <1-2-3. Other structural examples>

[0086] Referring Figure 7 other structural examples of the separation chamber forming portion 64 will be described. The turbulence promoting element 67a can be a protrusion, but can also be a notch or a hole. Figure 7 The example of EX1 illustrates an example in which the turbulence promoting element 67a is provided as a through hole formed in the surrounding wall of the discharge port 66. Such a hole also enables the generation of turbulence in the region R2.

[0087] Figure 7 The example of EX2 illustrates an example in which the cylindrical portion 65 is not provided. In this case, it is also preferable to make the cross-sectional area SC2 of the discharge port 66 larger than the cross-sectional area SC1' of the inlet port 65a'.

[0088] The opening portion 65b of the cylindrical portion 65 can also be an opening on an inclined surface rather than an opening on a horizontal surface. Figure 7 The example of EX3 illustrates an example in which the lower end of the tube portion 63 side of the cylindrical portion 65 protrudes more in the downward direction than the lower end of the side of the cylindrical portion 65 opposite the tube portion 63. By thus providing, it is easy to guide the ground coffee to the region R1 side, and thus it is possible to make the residence time of the ground coffee in the separation chamber SC long, and it is possible to improve the separation effect.

[0089] <2. Control device>

[0090] Referring to Figure 8 the control device 11 of the coffee bean grinding device 1 will be described. Figure 8 is a block diagram of the control device 11.

[0091] The control device 11 controls the entire coffee bean grinding device 1. The control device 11 includes a processing section 11a, a storage section 11b, and an I / F (interface) section 11c. The processing section 11a is, for example, a processor such as a CPU. The storage section 11b is, for example, a RAM, a ROM. The I / F section 11c includes an input and output interface for inputting and outputting signals between an external device and the processing section 11a. The I / F section 11c also includes a communication interface capable of performing data communication with a server 16, a portable terminal 17 via a communication network 15 such as the Internet. The server 16 is capable of communicating with the portable terminal 17 such as a smartphone via the communication network 15, and is capable of receiving, for example, a reservation for the manufacture of ground coffee, information of an impression, and the like from the portable terminal 17 of a demander. The system for grinding coffee beans is configured in a manner including the coffee bean grinding device 1, the server 16, and the portable terminal 17.

[0092] The processing section 11a executes a program stored in the storage section 11b, and controls an actuator group 14 based on an instruction from an information display device 12 or a detection result of a sensor group 13 or an instruction from the server 16. The sensor group 13 is various sensors provided to the coffee bean grinding device 1 (for example, an action position detection sensor of a mechanism, and the like). The actuator group 14 is various actuators provided to the coffee bean grinding device 1 (for example, a motor, and the like).

[0093] <3. Action Control Example>

[0094] Referring to Figure 9 a control processing example of the coffee bean grinding device 1 executed by the processing section 11a will be described. Figure 9 A control processing example of manufacturing ground coffee will be described. Further, this processing is an example of a case where the grinding processing is executed in accordance with order information from the outside (for example, the server 16, the portable terminal 17) of the coffee grinding device 1.

[0095] In step S1, it is determined whether or not order information of ground coffee is received. In a case where the order information is not received, this step S1 is repeatedly executed. Also, in a case where the order information is received, the processing proceeds to step S2. Further, the specific content of the order information will be described later.

[0096] In step S2, the received order information is displayed in the information display device 12, and the processing proceeds to step S3.

[0097] In step S3, it is determined whether or not the grinding start operation of the coffee beans has been accepted. In the case where the grinding start operation has not been accepted, step S4 is entered, and in the case where the grinding start operation has been accepted, step S6 is entered.

[0098] In step S4, it is determined whether or not the change operation of the order information has been accepted. In the case where the change operation of the order information has been accepted, step S5 is entered, and in the case where the change operation of the order information has not been accepted, step S3 is returned to.

[0099] In step S5, the received order information is updated in accordance with the change operation of the order information, and step S3 is returned to.

[0100] During the period from the reception of the order information until the grinding start operation is accepted, the received order information can be changed by steps S4 and S5. The grinding start operation and the change operation of the order information are not limited to the operations of the information display device 12, and can be configured to accept operations from the portable terminal 17, and the information of the operations can be transmitted to the coffee bean grinding device 1, and the transmission path can be an arbitrary path.

[0101] In step S6, the grinding process of the coffee beans is executed. First, the roasted coffee beans of the amount specified by the order information are supplied from the storage device 4 to the grinder 5A. The coffee beans that are crushed by the grinder 5A are separated from the impurities by the separating device 6, and then supplied to the grinder 5B. In this grinder 5B, the coffee beans are ground while changing the interval between the fixed blade 57b and the rotating blade 58b at a predetermined interval (for example, 50 μm pitch) in accordance with the order information, and the ground coffee beans are discharged from the discharge port 51b. When the grinding process is completed, the manufacturing process of the ground coffee beans is completed.

[0102] In the above example, the case where the grinding process is executed in accordance with the order information from the outside of the coffee grinding bean device 1 is described, but it can also be configured to directly input the order information to the coffee grinding bean device 1 using the information display device 12. In the case of this configuration, it can also be configured to delete Figure 9 steps S2, S4, and S5 after the configuration.

[0103] In addition, in the above example, the order information can be changed during the period from the reception of the order information until the grinding start operation is accepted, but such a change opportunity can not be provided, and the grinding process can be started directly after the reception of the order information.

[0104] <4. Order and Action Example>

[0105] Next, the flow of the control process described using Figure 9 will be described, and the flow of the control process described using Figures 10-15An example of the order information will be described. Figures 10-12 is a diagram showing a case at the time of input of order information. Figure 13 is a diagram showing a case at the time of change of order information. Figure 14 is a diagram showing an example of control parameters of the grinder 5B for an order. Figure 15 is a diagram showing an example of display in execution of the grinding process.

[0106] In this example, it is assumed that the portable terminal 17 is installed with an application program for transmitting order information on coffee ground. In Figure 10 an example of an input screen of order information using the application program is shown. In this input screen, a title input field 171 of an order, an input table 172 for specifying a ratio of a particle size at the time of grinding coffee beans, a fine→coarse grinding button 173a indicating a grinding method of changing from a fine grinding state to a coarse grinding state, and a coarse→fine grinding button 173b indicating a grinding method of changing from a coarse grinding state to a fine grinding state, a chart area 174 for displaying the contents input to the input table 172 by a chart, and a transmission button 175 for transmitting order information are displayed.

[0107] In Figure 11 an example of an input screen of a state in which order information is input is shown. In this input screen, a character such as "Rice Summer suitable for French press" is input in the title input field 171. In addition, in the input table 172, "40" indicating a ratio of a particle size of 200 μm and "60" indicating a ratio of a particle size of 800 μm are input and the total ratio thereof is "100"%. In addition, a comment corresponding to each of the particle sizes of 200 μm, 800 μm, and the total is input. In addition, the coarse→fine grinding button 173b is selected. In the chart area 174, the contents input to the input table 172 are displayed in the form of a chart. In this chart, two peaks are shown, in which the left peak indicates a case where the particle size of 200 μm is 40% of the ratio, and the right peak indicates a case where the particle size of 800 μm is 60% of the ratio.

[0108] In the chart area 174, by dragging a part of the chart, the contents input to the input table 172 can be indirectly changed. In Figure 12 an example in which the right peak of the chart area 174 shown in Figure 11 is moved to the left is shown. Also, a case in which "60" indicating a ratio of a particle size of 800 μm input to the input table 172 is changed to "0" and "0" indicating a ratio of a particle size of 600 μm is changed to "60" by this operation is shown. By such an input method based on dragging of the chart, not only the particle size but also the ratio can be changed. For example, it can be configured that by up and down dragging of a part of the chart, the ratio of the corresponding particle size can be increased or decreased.

[0109] In addition, Figure 12 In the example shown, after a value is entered into input table 172, the value entered into input table 172 is changed by dragging a portion of the chart. However, this structure is not limited to this; it could also be a chart displaying the initial state (a flat line, in the chart area 174) from the state before values ​​were entered into input table 172 (the initial state). Figure 10 (Represented by thick lines in the middle), the value of input table 172 can be set by dragging this chart.

[0110] By using the chart input method described above, users can more intuitively set the granularity ratio.

[0111] Alternatively, the size of one peak can be increased or decreased in such a way that increasing the size of one peak relatively decreases the size of another peak, thereby relatively increasing or decreasing the size of the other peak. This allows for more efficient use of the chart area 174 when its size is limited.

[0112] After setting the title, particle size ratio, grinding method, and amount of coffee beans (in... Figures 10-12 (Not shown in the diagram) After clicking the send button 175, the order information is sent to the control device 11 of the coffee bean grinding device 1 via the communication network 15. Alternatively, it can be temporarily sent to the server 16 and then sent to the control device 11 of the coffee bean grinding device 1 via the server 16 and the communication network 15.

[0113] When order information is received, the content of the received order information is displayed on the information display device 12. Figure 9 In step S1, the answer is "Yes"; in step S2... Figure 13 (A) shows that the control device 11 receives a signal from the controller. Figure 12 The example shown is an order information sent and displayed on the information display device 12. Specifically, the information entered into the receiving table 121 is displayed. Figure 12 The title of the title input field 171, and the rows in the input table 172 with a granularity other than a scale of 0 and an empty remarks column (in Figure 12 The content excluding the rows for particle sizes of 400μm and 1000μm. Furthermore, the grinding method indicator column 122 shows the content obtained by... Figure 12 The selection of the coarse → fine grind button 173b indicates the grinding mode, switching from coarse to fine grind. Additionally, the amount of beans received (60g in this example) is displayed in the bean quantity field 123. Alternatively, the bean quantity can be set separately by the store.

[0114] When the "Start Grinding" button 124 is clicked in this state, the coffee bean grinding process will begin (details will be described later). However, in the state before clicking the "Start Grinding" button 124, it is possible to change the order information (in...). Figure 9 In step S3, the answer is "No," in step S4, the answer is "Yes," and in step S5... If the order information has been changed, the coffee beans will be ground according to that information. The particle size of the coffee beans may sometimes be finer (or coarser) depending on the temperature and humidity during grinding, but this can be adjusted by changing the order information at the store.

[0115] For example, consider the following situation: Although received Figure 13 The order information for (A) is provided, but due to the low humidity, the coffee beans are ground into finer particles. At this time, for example... Figure 13 As shown in (B), in receiving table 121, changing "40" representing the proportion of 200μm particle size to "45" and changing "60" representing the proportion of 600μm particle size to "55" allows the particle size of the coffee beans to be coarsened to the desired size. Furthermore, in this... Figure 13 In example (B), the note column adds the note "low humidity → percentage increase". By having such a note, information such as the reason for the correction can sometimes be conveyed.

[0116] Next, in Figure 13 Let's take the case shown in (B) where the "Start Grinding" button 124 has been clicked as an example to illustrate the actions after clicking the "Start Grinding" button 124. When the "Start Grinding" button 124 is clicked, the coffee beans are ground according to the order information. Figure 9 In step S3, the answer is "Yes" (step S6). Figure 14 (A) shows that Figure 13 The particle size and its proportion specified in (B).

[0117] In this grinding process, the following control is performed: coffee beans are ground while the blade spacing (the spacing between the fixed blade 57b and the rotating blade 58b) of the grinder 5B is changed at predetermined intervals (e.g., 50 μm scales) to expand the particle size distribution of the produced coffee beans to a certain range (in this embodiment, ±100 to 150 μm) relative to the particle size of the coffee beans specified in the order information. For example, in Figure 14 (B) shows the target in Figure 14 In (A), the specified particle size of 200 μm is set with an operating time for changing the blade spacing of the grinder 5B within the range of 50 to 350 μm. Additionally, in Figure 14 (B) shows the target in Figure 14In (A), the specified particle size of 600 μm is set with an operating time for changing the blade spacing of the grinder 5B within the range of 450 to 700 μm. Furthermore, in Figure 14 In (D), the diagram is shown. Figure 14 The length of the operating time of each interval of the blades of the grinder 5B shown in (B) is shown. Furthermore, the interval of the blades of the grinder 5B and its operating time set here correspond to the particle size distribution of the coffee beans to be ground, so it can also be said that the particle size distribution is set.

[0118] In the example above, it is assumed that it takes a total of 30 seconds to grind the coffee beans to produce the 60g quantity specified in the order information. Furthermore, 45% (13.5 seconds) of this action time is allocated to the action targeting a 200μm particle size. In the example above, the action is performed while varying the blade spacing of the grinder 5B within the range of 50 to 350μm, thus allocating 13.5 seconds of action time to the grinder action within this range, specifically targeting a 200μm particle size. Furthermore, in... Figure 14 In (B), the total operating time of the grinder within the range of 50–350 μm is 13.5 seconds. Furthermore, 55% (16.5 seconds) of the total 30-second operating time is allocated to the operation targeting a particle size of 600 μm. In the example above, for the specified particle size of 600 μm, the grinder 5B operates while varying the blade spacing within the range of 450–700 μm; therefore, 16.5 seconds of operating time is allocated to the grinder operation within this range. Furthermore, in Figure 14 In (B), the total operating time of the grinder within the range of 450–700 μm is 16.5 seconds. As explained above, Figure 14 The action time shown in (B) is derived from the time required to grind coffee beans. Furthermore, in Figure 14 (B) illustrates an example where the range of blade spacing for the two grit sizes specified by the grinder 5B does not overlap, but in cases where these ranges overlap, the action times of that part are added together.

[0119] As in Figure 14 As illustrated in example (B), by varying the blade spacing of the grinder 5B while grinding coffee beans, the particle size of the coffee beans can be dispersed. Coffee extracted from dispersed coffee beans can contain a wider range of flavors compared to coffee extracted from undispersed coffee beans. Furthermore, settings can be configured for those who dislike such flavors, for example... Figure 14 The action time is as shown in (C). Figure 14In (C), the operation time of the grinder 5B is set only for the operation at the interval of the knife for which the value of the grain size specified by the order information is the same, and the operation time corresponds to the grain size distribution in which the dispersion of the grain size is suppressed. These structures are one example, and it is also possible to set a range of the grain size distribution that can be specified when the grain size is specified.

[0120] In addition, in Figure 14 In the example of (B), the operation time at the interval of the knife for which the value of the grain size specified by the order information is the same is the longest, and as the difference between the specified grain size and the interval of the knife of the grinder 5B becomes larger, the operation time becomes shorter, but for example, it is also possible to set the operation time to the same value for the operation at the interval of the knife of the grinder 5B for ±50 μm with respect to the specified grain size, and it is also possible to set a plurality of modes of the grain size distribution and be able to select from among them.

[0121] In addition, it is also possible to be able to input information such as Figure 14 the operation time of (B) at the time of making the order information, and in the case where the information of the operation time is included in the order information, the grinding processing can be performed in accordance with the information.

[0122] Further, in Figure 14 (A), the values of two grain sizes are set, but as for the number of kinds of grain sizes for which the values are specified, it is also possible to be not a plurality but one. For example, in the case where the value of one grain size is set, the operation time is set based on the value.

[0123] Further, the grinding method of the grinder 5B in the present embodiment has two kinds of a grinding method in which the fine grinding state is changed to the coarse grinding state and a grinding method in which the coarse grinding state is changed to the fine grinding state, and a certain grinding method is specified using the fine→coarse grinding button 173a and the coarse→fine grinding button 173b described in Figure 10-12 In the case where the grinding method in which the fine grinding state is changed to the coarse grinding state is specified, the interval of the knife of the grinder 5B is expanded from 50 μm to 1000 μm, and the grinder 5B is caused to operate at the operation time set for each interval. On the other hand, in the case where the grinding method in which the coarse grinding state is changed to the fine grinding state is specified, the interval of the knife of the grinder 5B is reduced from 1000 μm to 50 μm, and the grinder 5B is caused to operate at the operation time set for each interval. The grain size distribution of the coffee ground beans manufactured sometimes has a subtle difference depending on the grinding method, and thus the taste can have a difference, and therefore a structure in which these grinding methods can be set is adopted in the present embodiment.

[0124] In Figure 13In (B) of FIG. 6, since the grinding mode in which the coffee beans are ground from the coarse grinding state to the fine grinding state is specified, the interval of the knives of the grinder 5B is narrowed from 1000 μm to 50 μm, and the grinder 5B is caused to operate with the operation time set for each interval. At this time, the graph shown in (D) of FIG. 6 is displayed in the information display device 12, and the color of the area within the graph changes according to the progress of the operation. In (D) of FIG. 6, the color of the area on the right side of the 550 μm is changed. This is an example in which the grinding processing of the area is completed. In (B) of FIG. 6, the case where 30 seconds have passed from the start of the grinding and the grinding processing is completed is shown. In this (B) of FIG. 6, all of the areas are marked with a hatching, which is an example in which all of the grinding processing is completed. As in the examples of (A), (B) of FIG. 6, by displaying the progress of the grinding processing, the waiting time of the customer can be made less boring, or the work of the clerk during this period can be made efficient. Figure 14 Figure 15 Figure 15 Figure 15 Figure 15 Figure 15

[0125] In addition, in the examples of (A), (B) of FIG. 6, a display example in which the hatching gradually expands from the right side of the graph is explained in the case where the grinding mode in which the coffee beans are ground from the coarse grinding state to the fine grinding state is specified, but in the case where the grinding mode in which the coffee beans are ground from the fine grinding state to the coarse grinding state is specified, the hatching is displayed so as to gradually expand from the left side of the graph, unlike the examples of (A), (B) of FIG. 6. Figure 15 Figure 15

[0126] In addition, in the above examples, a structure in which the progress of the grinding processing is displayed in the information display device 12 is explained, but a structure in which the progress of the grinding processing is displayed in the portable terminal 17 from which the order information is transmitted can also be employed.

[0127] <5. Other Structures>

[0128] In the coffee bean grinding device 1 explained above, a structure in which the pulverizing device 5 grinds the coffee beans in two stages using the grinder 5A and the grinder 5B is employed. However, when the operation explained using FIG. 6 is performed, the structure is not limited to this, and a structure in which one grinder is used can also be employed, and the mechanism of the grinder is not limited to the mechanism explained above. Figures 9-15

[0129] In addition, as in the case where the coffee bean grinding device 1 explained using FIG. 6 is employed, the portable terminal 17 can be used as the order information input device 14. Figure 14 ​​​​​​​​​As explained, when dispersing the particle size of coffee beans, the structure can be configured as follows: Two grinders are used, one for a particle size range of 50μm and smaller than 500μm, and the other for a particle size range of 500μm and larger to 1000μm. These two grinders are used alternately based on order information, or both can be used simultaneously. That is, the structure can be configured to use multiple grinders alternately or simultaneously. Furthermore, the multiple grinders are not limited to a structure where each grinder is responsible for a different particle size range; they can also be a structure where these ranges overlap, or they can be the same.

[0130] Furthermore, in the example described above, an information display device 12 was used to display coffee bean order information or initiate the grinding operation. However, it is also possible for such a task to be performed by an external device such as a portable terminal 17 or a server 16. That is, a coffee bean grinding system including a coffee bean grinding device 1 and a server 16 or a portable terminal 17 can also be constructed.
