[0005] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2020-043899 Summary of the Invention

[0006] Problems to be Solved by the Invention

[0007] Although not explicitly stated in Patent Document 1 above, the extractor includes an extraction unit for performing a beverage extraction operation and a drive unit for driving the extraction unit, and the extraction unit is detachably provided on the drive unit. In such an extractor, the extraction unit is attached to the drive unit by meshing a transmission gear of the drive unit with a gear to be transmitted of the extraction unit.

[0008] Further, in this extractor, if the gear to be transmitted is not disposed at the origin position, the extraction unit cannot be attached to the drive unit, but the drive unit has a characteristic that the extraction unit can be attached even if the transmission gear is not at the origin position.

[0009] Therefore, by meshing the gear to be transmitted disposed at the origin position with the transmission gear not at the origin position, the extraction unit is attached to the drive unit in a state where so-called gear misalignment occurs, whereby the extractor can be configured in appearance.

[0010] However, in an extractor configured in a state where such gear misalignment occurs, an abnormality is caused during beverage extraction, and as a result, it may be impossible to supply the beverage.

[0011] In view of the above actual situation, an object of the present invention is to provide a beverage supply device capable of suppressing the extraction unit from being attached to the drive unit in a state where gear misalignment occurs.

[0012] Means for Solving the Problems

[0013] To achieve the above object, the present invention provides a beverage supply device, which includes an extractor for extracting a beverage by inputting crushed raw materials and hot water into the extractor. The beverage supply device supplies the beverage extracted by the extractor to a container. The beverage supply device is characterized in that the extractor includes: an extraction unit for performing the extraction operation of the beverage; and a drive unit for driving the extraction unit. The extractor is constituted by engaging a transmission gear of the drive unit with a gear to be transmitted of the extraction unit. The beverage supply device includes: a detection component for detecting whether the extraction unit has disengaged from the drive unit; and a control component for rotating the transmission gear to a specified origin position when the detection component detects that the extraction unit has disengaged from the drive unit.

[0014] In addition, the present invention is characterized in that, in the above beverage supply device, when an abnormality occurs, the control component rotates the transmission gear to the origin position, and then when the detection component detects that the extraction unit has disengaged from the drive unit, the control component rotates the transmission gear to a specified origin position.

[0015] In addition, the present invention is characterized in that, in the above beverage supply device, when the control component has rotated the transmission gear to the origin position when the abnormality occurs, the control component performs a notification operation for notifying that the extraction unit can be taken out from the drive unit.

[0016] Effects of the Invention

[0017] According to the present invention, the extractor includes: an extraction unit for performing the extraction operation of the beverage; and a drive unit for driving the extraction unit. The extractor is constituted by engaging a transmission gear of the drive unit with a gear to be transmitted of the extraction unit. The detection component detects whether the extraction unit has disengaged from the drive unit. When the detection component detects that the extraction unit has disengaged from the drive unit, the control component rotates the transmission gear to a specified origin position. Therefore, it has the effect of suppressing the extraction unit from being installed in the drive unit in a state where gear misalignment has occurred. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Figure 1 and Figure 2 are respectively diagrams showing the beverage supply device according to the implementation mode of the present invention. Figure 1 is a perspective view showing the external structure. Figure 2 is a schematic diagram schematically showing each component.

[0037] The beverage supply device illustrated herein is a coffee machine installed in a store such as a convenience store. For example, it extracts coffee powder and drip liquid and supplies beverages such as coffee to a cup C as a container. Such a beverage supply device includes a device main body 1.

[0038] The device main body 1 is configured to include a main body cabinet 10 and a front surface door 20. The main body cabinet 10 has a substantially rectangular parallelepiped shape with an opening (hereinafter also referred to as a front surface opening) not shown on the front surface. Inside the main body cabinet 10, a control part 60 and a beverage generation part 30 for generating beverages (such as coffee) are provided.

[0039] The front surface door 20 is a door body having a size sufficient to close the front surface opening of the main body cabinet 10. The front surface door 20 is provided at the left edge portion on the front side of the main body cabinet 10 so as to be able to swing around the central axis of a shaft portion not shown extending in the vertical direction, and can open and close the front surface opening of the main body cabinet 10.

[0040] The front surface of the front surface door 20 constitutes a customer-facing surface, and a display part 21, a beverage supply part 22, and an opening / closing door 23 are provided.

[0041] The display unit 21 is constituted by, for example, a liquid crystal touch panel, displays various information according to instructions provided by the control unit 60, and can perform input operations such as touch operations. When an input operation such as a touch operation is performed, the display unit 21 sends a sales signal to the control unit 60.

[0042] The beverage supply unit 22 is provided at a position below the display unit 21 and has a mounting table 22a. The mounting table 22a is for mounting the cup C and is provided with an arc-shaped stopper (not shown).

[0043] The opening and closing door 23 is made of a transmissive material such as transparent resin and has a size sufficient to cover the beverage supply unit 22. The left end of the opening and closing door 23 is pivotally supported on the front surface door 20 and can swing in the front-rear direction. That is, the opening and closing door 23 can swing in the front-rear direction in a form approaching and separating from the beverage supply unit 22. When swinging backward in a form approaching the beverage supply unit 22, the beverage supply unit 22 can be closed, and when swinging forward in a form separating from the beverage supply unit 22, the beverage supply unit 22 can be opened.

[0044] The beverage generation unit 30 will be described below. The beverage generation unit 30 is configured to include a raw material box 31, a grinder 33, a hot water supply unit 35, an extractor 37, a storage barrel 39, a compressed air supply pipeline 41, a drainage pipeline 43, and a nozzle 45.

[0045] The raw material box 31 is for storing roasted coffee beans as beverage raw materials and is provided in a form that partially protrudes upward from the top plate portion 12 of the main cabinet 10. The raw material box 31 is provided with a raw material supply drive unit 311. The raw material supply drive unit 311 is driven when a drive instruction is provided by the control unit 60. The raw material supply drive unit 311 is for discharging a specified amount of coffee beans included in the drive instruction.

[0046] The grinder 33 is a machine called a so-called mill and is driven when a drive instruction is provided by the control unit 60. The grinder 33 is provided in the lower area of the raw material box 31 and is connected to the raw material box 31 via a raw material chute 32.

[0047] When the grinder 33 is driven, the coffee beans discharged from the raw material box 31 and guided by the raw material chute 32 are ground, and the ground coffee beans (hereinafter also referred to as coffee ground beans) are put into the extractor 37 through a powder chute 34. Here, the powder chute 34 is configured to integrate each component with resin.

[0048] The hot water supply unit 35 is for supplying hot water to the extractor 37 and is configured such that a hot water tank 351, a metering pump 352, an auxiliary tank 353, a hot water supply pump 354, and a check valve 355 are sequentially connected in a hot water supply pipeline 356 constituted by a hot water supply pipe.

[0049] The hot water tank 351 is used to heat water such as tap water supplied from a water supply unit (not shown) using a heater 351a and store it as hot water. The metering pump 352 is driven according to an instruction provided by the control unit 60. When driven, a fixed amount of hot water is delivered from the hot water tank 351 to the auxiliary tank 353. The volume of the auxiliary tank 353 is smaller than that of the hot water tank 351, and temporarily stores the hot water delivered by the metering pump 352. The hot water supply pump 354 is driven according to an instruction provided by the control unit 60. When driven, the hot water in the auxiliary tank 353 is pressurized and delivered to the extractor 37. The delivery volume of the hot water supply pump 354 is made larger than that of the metering pump 352. The check valve 355 is a valve element that allows the hot water delivered from the hot water supply pump 354 to pass through toward the extractor 37 but restricts the hot water from passing through from the extractor 37 toward the auxiliary tank 353. The check valve 355 is arranged in a state of being thermally connected to the hot water tank 351, which is not clearly shown in the drawings.

[0050] The extractor 37 is used to extract coffee from the ground coffee beans put in via the powder chute 34 from the grinder 33 and the hot water supplied from the hot water supply unit 35.

[0051] A beverage supply pipeline 38 is connected to such an extractor 37. The beverage supply pipeline 38 is composed of a single beverage supply pipe or is formed by connecting a plurality of beverage supply pipes, and is used to supply the coffee extracted by the extractor 37 to the nozzle 45.

[0052] A first pinch valve 381 is provided in the middle of the beverage supply pipeline 38. The first pinch valve 381 is opened and closed according to an instruction provided by the control unit 60. When in the open state, it allows the fluid to pass through, and when in the closed state, it restricts the fluid from passing through.

[0053] Also as Figure 3 shown, the extractor 37 is configured to include an extraction unit 37a and a drive unit 37b. The extraction unit 37a is used to perform the extraction operation of coffee as a beverage. The extraction unit 37a has a transmitted gear 37c. When the transmitted gear 37c is arranged at the origin position, the extraction unit 37a can be installed on the drive unit 37b.

[0054] The drive unit 37b has a transmission gear 37d. By meshing the transmission gear 37d with the transmitted gear 37c, the extraction unit 37a is installed to form the extractor 37. That is, the extraction unit 37a is detachably installed on the drive unit 37b.

[0055] The drive unit 37b is configured to drive a built-in drive source (not shown) according to an instruction provided by the control unit 60, thereby transmitting power from the transmission gear 37d to the driven gear 37c, driving the extraction unit 37a to perform an extraction operation.

[0056] The extraction unit 37a is configured to include a cylinder block 371, a lid 372, and a filter assembly (Japanese: フィルタブロック) 373. The cylinder block 371 has a substantially cylindrical shape. By driving the drive unit 37b according to an instruction provided by the control unit 60, the lid 372 moves in a manner of approaching and separating from the upper surface opening of the cylinder block 371 to open and close the upper surface opening of the cylinder block 371. A hole allowing the coffee ground beans supplied through the powder chute 34 to be introduced into the cylinder block 371 and a hole allowing the hot water supplied by the hot water supply unit 35 to be introduced into the cylinder block 371 are formed in the lid 372, and this structure is not clearly shown in the figure.

[0057] The filter assembly 373 is provided in the lower region of the cylinder block 371 and is connected to the beverage supply pipe 38. By driving the drive unit 37b according to an instruction provided by the control unit 60, the filter assembly 373 moves in the vertical direction in a manner of approaching and separating from the cylinder block 371.

[0058] In addition to the above drive source, the drive unit 37b, as Figure 3 and Figure 4 shown, further includes a home position detection unit 374 and a paper roller unit 375. The home position detection unit 374 is configured to detect whether the transmission gear 37d is in the home position and provide the detection result to the control unit 60.

[0059] The paper roller unit 375 is configured to hold the filter paper PF drawn out from the filter roller FR and guided by the guide roller GR. The filter roller FR is accommodated in the filter housing 47 in a rotatable manner. Here, the filter roller FR winds the filter paper PF. That is, the filter housing 47 supports and accommodates the filter roller FR that winds the filter paper PF used when extracting a beverage by the extractor 37 in a rotatable manner.

[0060] Such a paper roller unit 375 is configured to include a drive roller 3751 and a driven roller 3752.

[0061] The drive roller 3751 is a pair of left and right disk-shaped rollers that are connected to a common rotating shaft 3751a with their inner surfaces facing each other. The drive roller 3751 has a first tooth portion 3751b protruding radially outward on its outer peripheral portion. In addition, when the control unit 60 provides an operation instruction to the drive unit 37b, the drive roller 3751 rotates around the central axis of the rotating shaft 3751a.

[0062] The driven roller 3752 is located relatively lower than the driving roller 3751. Figure 5 As shown, the driven rollers 3752 are a pair of left and right rollers provided separately from each other on the stopper member 376 constituting the driving unit 37b with their inner surfaces facing each other. The driven rollers 3752 have second teeth 3752b protruding radially outward formed on the outer circumference.

[0063] A portion of the second tooth portion 3752b of the driven roller 3752 meshes with a portion of the first tooth portion 3751b of the corresponding driving roller 3751 to sandwich the filter paper PF, whereby the driven roller 3752 rotates around its own central axis as the driving roller 3751 rotates.

[0064] The stopper member 376 is a member formed of, for example, a resin material. Figure 6 As shown, the cutter section 377 and the rear connecting section 378 are provided. The cutter section 377 has a blade 377a for cutting the filter paper PF formed at the lower edge in the region below the pair of left and right driven rollers 3752. The cutter section 377 has a left component 3771 and a right component 3772.

[0065] The left component 3771 is connected to the portion where the left driven roller 3752 is provided. The right component 3772 is connected to the portion where the right driven roller 3752 is provided. The boundary between the left component 3771 and the right component 3772 is biased toward one side in the left-right direction, and in this embodiment, is biased toward the right side.

[0066] An engaging recess 3771a is formed at the right end of the left component 3771, and an engaging protrusion 3772a formed at the left end of the right component 3772 enters the engaging recess 3771a. The upper and lower dimensions of the engaging recess 3771a are larger than the upper and lower dimensions of the engaging protrusion 3772a, and a gap is formed between the lower surface of the upper edge 3771b of the engaging recess 3771a and the upper end surface of the engaging protrusion 3772a, and between the upper surface of the lower edge 3771c of the engaging recess 3771a and the lower end surface of the engaging protrusion 3772a. In addition, a gap is also formed between the left surface of the left edge 3771d of the engaging recess 3771a and the left end surface of the engaging protrusion 3772a.

[0067] Furthermore, a first engaging piece 3773 is provided on the upper edge 3771b of the engaging recess 3771a. Figure 7 As shown, the first engaging piece 3773 is formed on the rear surface of the upper edge portion 3771b and is a block-shaped portion extending downward to the rear area of the engaging protrusion 3772a.

[0068] The engaging protrusion 3772a is provided with a second engaging piece 3774. The second engaging piece 3774 is formed on the rear surface of the engaging protrusion 3772a and is a block-shaped portion extending downward to the rear region of the lower edge 3771c of the engaging recess 3771a.

[0069] Thus, the left component 3771 and the right component 3772 can be displaced in the up-down direction in accordance with the size of the gap between the engaging protrusion 3772a and the engaging recess 3771a. In addition, the left component 3771 is restricted to be displaced forward by the first engaging piece 3773 abutting against the engaging protrusion 3772a, and is restricted to be displaced backward by the lower edge 3771c of the engaging recess 3771a abutting against the second engaging piece 3774. On the other hand, the right component 3772 is restricted to be displaced forward by the second engaging piece 3774 abutting against the lower edge 3771c of the engaging recess 3771a, and is restricted to be displaced backward by the engaging protrusion 3772a abutting against the first engaging piece 3773.

[0070] Therefore, the cutter part 377 is configured such that the left component 3771 and the right component 3772 are engaged with each other in a state where they can be displaced up and down and displacement in the thickness direction of the cutter part 377, that is, the front-rear direction, is restricted.

[0071] The rear connecting portion 378 extends in the left-right direction on the rear side of the cutter portion 377 in a manner that connects the rear end of the portion where the left driven roller 3752 is provided and the rear end of the portion where the right driven roller 3752 is provided. The rear connecting portion 378 is provided in a manner that can sufficiently ensure the front-rear dimension between the rear connecting portion 378 and the cutter portion 377. Notches 378a are formed at the lower ends of the left and right end portions of the rear connecting portion 378.

[0072] Figure 8 Yes means Figure 2 The three-dimensional view of the storage bucket 39 shown in FIG. Figure 9 As shown, the storage bucket 39 is provided in the lower area of the extractor 37, and is used to store the extraction residue K (refer to Figure 14 ) together with the filter paper PF.

[0073] The storage barrel 39 illustrated here is in the form of a bottomed cylinder, and is formed in such a way that the front wall portion 391 is higher than the rear wall portion 392. In addition, a handle 393 is provided on the front surface of the front wall portion 391, and a protrusion 392a protruding upward is formed on the upper end surface of the rear wall portion 392 in the form of a pair of left and right.

[0074] The pressurized air supply pipeline 41 is formed by connecting a plurality of pressurized air supply pipes, with one end connected to the lid 372 and the other end connected to a middle portion of the beverage supply pipeline 38. An air pump 411, a second pinch valve 412, and a third pinch valve 413 are provided in the pressurized air supply pipeline 41.

[0075] The air pump 411 is driven according to an instruction provided by the control unit 60 and is used to compress and transport air. The second pinch valve 412 is provided at a position closer to one end side (the lid 372 side) than the air pump 411. The second pinch valve 412 opens and closes according to an instruction provided by the control unit 60. In the open state, it allows fluid to pass through, and in the closed state, it restricts fluid from passing through. The third pinch valve 413 is provided at a position closer to the other end side (the beverage supply pipeline 38 side) than the air pump 411. The third pinch valve 413 opens and closes according to an instruction provided by the control unit 60. In the open state, it allows fluid to pass through, and in the closed state, it restricts fluid from passing through.

[0076] The drainage pipeline 43 is composed of a single drainage pipe or formed by connecting a plurality of drainage pipes, and is arranged in a form that branches from a middle portion of the beverage supply pipeline 38 and extends to an upper region of the storage bucket 39. A fourth pinch valve 431 is provided in the drainage pipeline 43. The fourth pinch valve 431 opens and closes according to an instruction provided by the control unit 60. In the open state, it allows fluids such as waste liquid to pass through, and in the closed state, it restricts fluids such as waste liquid from passing through.

[0077] Thus, the storage bucket 39 stores the extraction residue K generated by the extractor 37 for extracting the beverage, the filter paper PF used in the extraction of the beverage, and the waste liquid generated by the cleaning of the extractor 37.

[0078] The nozzle 45 can be detached from and attached to a nozzle mounting portion (not shown) provided on the front surface door 20. By being mounted on the nozzle mounting portion, the nozzle 45 is arranged in a form facing the beverage supply portion 22. That is, the nozzle 45 is detachably arranged in a form facing the beverage supply portion 22. Such a nozzle 45 sprays the beverage supplied through the beverage supply pipeline 38 onto the cup C placed on the placement table 22a.

[0079] The control unit 60 is electrically connected to each part of the above-mentioned beverage generation unit 30, and is also electrically connected to the detachment detection unit 51 and the light source 52. Here, the detachment detection unit 51 is used to detect whether the extraction unit 37a has detached from the drive unit 37b and provides its detection result to the control unit 60. The light source 52 is composed of, for example, an LED or the like and is provided on or near the extractor 37. The light source 52 lights up, for example, in a flashing manner according to an instruction provided by the control unit 60.

[0080] The above control unit 60 uniformly controls the operations of the respective parts of the beverage supply device according to programs and data stored in a storage unit (not shown).

[0081] In addition, the control unit 60 can be implemented, 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), or by both software and hardware.

[0082] In the beverage supply device having the above structure, coffee can be supplied to the cup C placed on the placement table 22a of the beverage supply unit 22 in the following manner. In addition, as a prerequisite, hot water at a specified temperature is generated and stored in the hot water tank 351, the first pinch valve 381, the second pinch valve 412, and the fourth pinch valve 431 are in a closed state, and the third pinch valve 413 is in an open state.

[0083] By the user touching and operating the display unit 21, as Figure 10 shown, the control unit 60 that has received the sales signal of the selected beverage provides an instruction to the drive unit 37b to move the filter assembly 373 upward, and then provides a drive instruction to the raw material supply drive unit 311 to cause the grinder 33 to discharge an amount of coffee beans corresponding to the beverage, provides a drive instruction to the grinder 33 to grind the coffee beans and input them into the extractor 37. Then, the drive of the raw material supply drive unit 311 is stopped.

[0084] The control unit 60 drives the metering pump 352 to convey a fixed amount of hot water from the hot water tank 351 to the auxiliary tank 353, and drives the hot water supply pump 354 to pressurize the hot water in the auxiliary tank 353 and convey it to the extractor 37, thereby inputting hot water into the extractor 37. Then, the drives of the metering pump 352 and the hot water supply pump 354 are stopped.

[0085] Then, the control unit 60 drives the air pump 411, as Figure 11 shown, so as to supply pressurized air (pressurized air for stirring) to the cylinder 371 through a part of the beverage supply pipeline 38 to stir (forcefully stir) the ground coffee beans and hot water. Then, the drive of the air pump 411 is stopped.

[0086] The control unit 60 that has forcefully stirred the ground coffee beans and hot water in this way provides an instruction to the drive unit 37b to move the lid 372 downward to close the upper surface opening of the cylinder 371, makes the third pinch valve 413 in a closed state, makes the first pinch valve 381 and the second pinch valve 412 in an open state, and drives the air pump 411. In addition, the fourth pinch valve 431 remains in a closed state.

[0087] Thus, as Figure 12 shown, by supplying pressurized air (pressurized air for extraction) to the cylinder body 371, coffee is extracted. The extracted coffee is supplied to the nozzle 45 via the beverage supply pipeline 38 and is ejected from the nozzle 45 into the cup C.

[0088] After ejecting and supplying a predetermined amount of coffee into the cup C, the control unit 60 stops the driving of the metering pump 352, the hot water supply pump 354, and the air pump 411. Thus, the user swings the opening / closing door 23 in the opening direction, enabling the cup C to be taken out from the beverage supply unit 22.

[0089] After that, the control unit 60 moves the lid body 372 upward by providing an instruction to the drive unit 37b to open the upper surface opening of the cylinder body 371, thereby releasing the internal pressure of the cylinder body 371. Then, the control unit 60 supplies hot water from the hot water supply unit 35 to the extractor 37 to clean the inside of the cylinder body 371, and makes the fourth pinch valve 431 in an open state. As Figure 13 shown, the water remaining in the extractor 37 is discharged as waste liquid to the storage bucket 39 via the drain pipeline 43.

[0090] After discharging the waste liquid in this way, the control unit 60 makes the fourth pinch valve 431 in a closed state. As Figure 14 shown, an instruction is provided to the drive unit 37b to move the filter assembly 373 downward. Then, the control unit 60 provides an instruction to the drive unit 37b to operate the paper roll unit 375 to discharge a predetermined amount of filter paper PF, and the extraction residue K generated by the extraction of coffee is stored in the storage box 39 together with the filter paper PF, ending the coffee supply for this time.

[0091] Figure 15 It shows Figure 2 a flowchart showing the processing content of the drive unit origin alignment process implemented by the control unit 60 as shown.

[0092] While explaining the processing content of this drive unit origin alignment process, the operation of the beverage supply device will be explained. In addition, this process is performed when coffee is being extracted in the extractor 37.

[0093] In this drive unit origin alignment process, when an abnormality occurs in the extractor 37 (step S101: Yes), the control unit 60 provides an instruction to the drive unit 37b to stop the coffee extraction performed by the extractor 37 (step S102).

[0094] After stopping the coffee extraction in this way, the control unit 60 issues a drive instruction for the transmission gear 37d to the drive unit 37b (step S103), and enters a waiting state for waiting for the origin detection unit 374 to detect that the transmission gear 37d has been arranged at the origin position (step S104).

[0095] When the origin detection unit 374 detects that the transmission gear 37d is configured at the origin position (step S104: yes), the control unit 60 issues a drive stop instruction to the drive unit 37b to stop the transmission gear 37d (step S105), and lights up the light source 52 in a flashing manner, thereby performing a take-out display of the extraction unit 37a (step S106).

[0096] After displaying the removal of the extraction unit 37a in this way, the control unit 60 enters a waiting state for the separation detection unit 51 to detect that the extraction unit 37a is separated from the driving unit 37b (step S107).

[0097] When the detachment detection unit 51 detects that the extraction unit 37a has detached from the driving unit 37b (step S107: yes), the control unit 60 issues a drive instruction to the driving unit 37b for the transmission gear 37d (step S108), and enters a waiting state in which the origin detection unit 374 detects that the transmission gear 37d has been configured at the origin position (step S109).

[0098] When the origin detection unit 374 detects that the transmission gear 37d is configured at the origin position (step S109: yes), the control unit 60 issues a drive stop instruction to the drive unit 37b for the transmission gear 37d (step S110), and enters a waiting state (step S111) in which the detachment detection unit 51 detects that the extraction unit 37a is installed on the drive unit 37b.

[0099] When the detachment detector 51 detects that the extraction unit 37a is attached to the driving unit 37b (step S110: Yes), the control unit 60 turns off the flashing light source 52 to resolve the abnormality (step S112), and then returns to the step to end the current processing.

[0100] According to the beverage supply device of the embodiment of the present invention described above, since the cutter portion 377 of the stopper member 376 is configured by engaging the left component 3771 and the right component 3772 in a manner that they can be displaced up and down, even if a part of the extraction residue K dropped from the filter paper PF falls on the driven roller 3752 or a part of the extraction residue K attached to the filter paper PF is separated from the portion sandwiched between the driving roller 3751 and the driven roller 3752 and falls on the driven roller 3752 and accumulates between the second tooth portion 3752b of the driven roller 3752 on either side to separate the driven roller 3752 from the corresponding driving roller 3751, it is possible to suppress the separation of the other driven roller 3752 from the corresponding driving roller 3751. Thus, the filter paper PF can be well sandwiched by the other driven roller 3752 and the corresponding driving roller 3751, and a reduction in the amount of the filter paper PF conveyed can be suppressed.

[0101] With the above beverage supply device, since the cutting tool part 377 is constituted by engaging a left-side component 3771 and a right-side component 3772 in a state where they can be displaced vertically with respect to each other and their displacement in the thickness direction of the cutting tool part 377, i.e., the front-rear direction, is restricted, the filter paper PF can be cut well at the cutting edge 377a. In particular, the boundary part between the left-side component 3771 and the right-side component 3772 is biased to the right. For the cutting tool part 377, since the engaging part of the left-side component 3771 and the right-side component 3772 is biased to the right, most of the cutting edge 377a can be constituted by the left-side component 3771, and the filter paper PF can be cut well.

[0102] With the above beverage supply device, since the rear connecting part 378 of the stopper member 376 is provided in such a manner that the front-rear dimension between it and the cutting tool part 377 can be sufficiently ensured, the gap between the rear connecting part 378 and the cutting tool part 377 can be sufficiently increased, the space in the upper region of the storage barrel 39 can be sufficiently increased, and the filter paper PF can be prevented from being stored in the storage barrel 39 in a dense state. In particular, by providing a protrusion 392a on the upper end surface of the rear wall part 392 of the storage barrel 39, the filter paper PF temporarily stored when the storage barrel 39 is pulled forward can be prevented from falling by the protrusion 392a.

[0103] With the above beverage supply device, when an abnormality occurs, the control component 60 rotates the transmission gear 37d to the origin position. After that, when the detachment detection part 51 detects that the extraction unit 37a has detached from the drive unit 37b, the control component 60 rotates the transmission gear 37d to a specified origin position. Therefore, it is possible to prevent the extraction unit 37a from being installed on the drive unit 37b in a state where gear misalignment has occurred.

[0104] As described above, the preferred embodiments of the present invention have been described, but the present invention is not limited thereto, and various modifications can be made.

[0105] In the above embodiment, the left-side component 3771 and the right-side component 3772 of the cutting tool part 377 are engaged in a state where they can be displaced vertically with respect to each other and their displacement in the thickness direction of the cutting tool part 377 is restricted. However, in the present invention, the left-side component and the right-side component of the cutting tool part may also be configured to be engaged in a manner that they can be displaced vertically with respect to each other.

[0106] In the above-described embodiment, an engaging recess 3771a is formed in the left-side component 3771 of the tool unit 377, and an engaging protrusion 3772a is formed in the right-side component 3772. However, in the present invention, it may also be that an engaging protrusion is formed in the left-side component and an engaging recess is formed in the right-side component.

[0107] In the above-described embodiment, when an abnormality occurs, the control unit 60 rotates the transfer gear 37d to the origin position. Thereafter, when the detachment detection unit 51 detects that the extraction unit 37a has detached from the drive unit 37b, the control unit 60 rotates the transfer gear 37d to a specified origin position. However, in the present invention, it may also be that when the detection component detects that the extraction unit has detached from the drive unit, the control unit rotates the transfer gear to a specified origin position.
