Description

Technical Field

[0001] This invention relates to the technical field of smart vending machines, and more particularly to an extraction device. Background Technology

[0002] Nowadays, with the development of beverage extraction technology, various styles of fully automatic or semi-automatic capsule coffee machines are being promoted and applied in shopping malls, milk tea shops, coffee shops, bakeries, and other places. However, the extraction base of the extraction device in existing fully automatic or semi-automatic capsule coffee machines is fixed and does not move. That is, after the extraction head injects water to extract the coffee capsule placed on the extraction base, the coffee capsule needs to be manually removed for waste disposal. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an extraction device that aims to solve the problem that after the extraction head of a capsule beverage machine extracts water from the capsule beverage placed on the extraction base, the capsule beverage needs to be manually removed for waste recycling.

[0004] This invention provides an extraction apparatus, comprising:

[0005] Extraction apparatus frame;

[0006] The extraction pressure motor is mounted on the frame of the extraction device;

[0007] An extraction head connected to the first rotating shaft of the extraction pressure motor via a first connecting rod structure;

[0008] The extraction base transmission motor is mounted on the frame of the extraction device;

[0009] The extraction base is connected to the second rotating shaft of the transmission motor of the extraction base via a second connecting rod structure;

[0010] An extraction base motion rail base is provided on the frame of the extraction device. An extraction base first motion rail group is provided on the extraction base motion rail base. The extraction base can slide along the extraction base first motion rail group. The extraction base transmission motor can drive the extraction base to move along the extraction base first motion rail group to below the extraction head, or to move along the extraction base first motion rail group to a distance away from the extraction head.

[0011] In the extraction device of this invention, the extraction pressure motor drives the extraction head downward to the processing position via a first linkage structure to extract the beverage capsules at the processing position. After extraction is completed, the extraction base transmission motor drives the extraction base to move away from the extraction head via a second linkage structure, thereby achieving material discharge.

Figures 1-4 As shown, the extraction device 30 includes:

[0024] Extraction unit frame 300;

[0025] An extraction pressure motor 310 is mounted on the frame 300 of the extraction device;

[0026] An extraction head 330 is connected to the first rotating shaft of the extraction pressure motor 310 via a first connecting rod structure 320.

[0027] An extraction base transmission motor 340 is mounted on the frame 300 of the extraction device;

[0028] An extraction base 360 ​​is connected to the second rotating shaft of the extraction base transmission motor 340 via a second connecting rod structure 350.

[0029] An extraction base motion rail base 370 is provided on the extraction device frame 300. An extraction base first motion rail group 371 is provided on the extraction base motion rail base 370. The extraction base 360 ​​can slide along the extraction base first motion rail group 371. The extraction base transmission motor 340 can drive the extraction base 360 ​​to move along the extraction base first motion rail group 371 to below the extraction head 330, or to move along the extraction base first motion rail group 371 away from the extraction head 330.

[0030] In this embodiment, the extraction device 30 is preferably installed in a smart vending machine, such as an automated beverage vending machine for brewing drinks. When it is necessary to extract beverage capsules for brewing, beverage capsules in the storage device of the smart vending machine move to the processing position on the extraction base 360. At this time, the extraction pressing motor 310 drives the extraction head 330 downward to the processing position through the first linkage structure 320 to extract the beverage capsules at the processing position. After extraction is completed, the extraction base transmission motor 340 drives the extraction base 360 ​​to move away from the extraction head 330 through the second linkage structure 350, thereby achieving material disposal. For example, if a waste recycling bin is set below the extraction device 30, the extraction base transmission motor 340 can drive the extraction base 360 ​​to achieve material disposal for waste recycling.

[0031] In one embodiment, such as Figures 1-4 As shown, the first link structure 320 includes:

[0032] A first connecting handle 321, one end of which is connected to the first rotating shaft;

[0033] The first fulcrum rod 322 is fixed at both ends to the frame 300 of the extraction device;

[0034] A first connecting rod 323, one end of which is connected to the other end of the first connecting handle 321 and the middle part of which is sleeved on the first fulcrum rod 322;

[0035] A second connecting rod 324, one end of which is connected to the other end of the first connecting rod 323;

[0036] An extraction head holder 325 is connected to the other end of the second connecting rod 324, and the extraction head holder 325 is used to fix the extraction head 330.

[0037] In this embodiment, the first connecting rod structure 320 is configured as described above, which can effectively transmit the driving force of the extraction pressure motor 310 to the extraction head 330. The first fulcrum rod 322 functions similarly to a fulcrum in a lever structure, and the first connecting rod 323 can rotate around the first fulcrum rod 322 as a pivot point. Specifically, when the first rotating shaft of the extraction pressure motor 310 rotates, it drives the first connecting handle 321 to rotate. Since one end of the first connecting rod 323 is connected to the first connecting handle 321, and the middle part of the first connecting rod 323 is sleeved on the first fulcrum rod 322, the rotation of the first connecting handle 321 drives the first connecting rod 323 to rotate around the first fulcrum rod 322 as a pivot point. Since one end of the second connecting rod 324 is connected to the other end of the first connecting rod 323, the second connecting rod 324 can also move under the influence of the first connecting rod 323. Since the extraction head holder 325 is connected to the other end of the second connecting rod 324, when the second connecting rod 324 moves, it can also drive the extraction head holder 325 to move downwards or downwards, thereby driving the extraction head 330 to approach or move away from the processing position on the extraction base 360.

[0038] In one embodiment, such as Figures 1-4 As shown, a first sensing element group 3231 is also provided at one end of the first connecting rod 323 near the first connecting handle 321. Correspondingly, a first photoelectric sensor 301a and a second photoelectric sensor 301b are provided on the extraction device frame 300. The position of the first photoelectric sensor 301a on the extraction device frame 300 is denoted as the first position, and the position of the second photoelectric sensor 301b on the extraction device frame 300 is denoted as the second position. When the first photoelectric sensor 301a detects that the first sensing element group 3231 has moved to the first position, it generates a first sensing signal. When the second photoelectric sensor 301b detects that the first sensing element group 3231 has moved to the second position, it generates a second sensing signal.

[0039] In this embodiment, a first photoelectric sensor 301a and a second photoelectric sensor 301b are provided on the extraction device frame 300 to detect the current movement state of the first connecting rod structure 320, and more specifically, to detect the current position of the first sensing plate group 3231 on the first connecting handle 321. For example, the first photoelectric sensor 301a is located at a first position on the extraction device frame 300 and the second photoelectric sensor 301a is located at a second position on the extraction device frame 300. Figure 3 .

[0040] When the first photoelectric sensor 301a detects that the first sensing plate group 3231 has moved to the first position, it generates a first sensing signal, indicating that the driving force of the extraction pressing motor 310 has been transmitted to the extraction head 330 through the first linkage structure 320, causing the extraction head 330 to move to the working position of the extraction base 360.

[0041] When the second photoelectric sensor 301b detects that the first sensing plate group 3231 has moved to the second position, it generates a second sensing signal, indicating that the driving force of the extraction pressing motor 310 has been transmitted to the extraction head 330 through the first linkage structure 320, causing the extraction head 330 to move to the initial position of the extraction head away from the extraction base 360.

[0042] By setting the first photoelectric sensor 301a and the second photoelectric sensor 301b, the movement of the extraction head 330 driven by the extraction head holder 325 can be effectively limited within a defined range.

[0043] In one embodiment, such as Figures 1-4 As shown, the extraction head holder 325 includes:

[0044] The upper end fixing rod 3252 is fixed at both ends to the frame of the extraction device;

[0045] The upper end 3254 of the extraction head fixing bracket is sleeved on the upper end fixing rod 3252 at one end;

[0046] An extraction head fixing frame connecting rod 3251 extends through the other end of the upper end 3254 of the extraction head fixing frame, and the end of the second connecting rod 324 away from the first connecting rod 323 is sleeved on the extraction head fixing frame connecting rod 3251; wherein, the extraction head fixing frame connecting rod 3251 is located below the upper end fixing rod 3252;

[0047] One end of the extraction head fixing bracket is sleeved on the lower end 3253 of the extraction head fixing bracket connecting rod 3251, and the other end of the lower end 3253 of the extraction head fixing bracket is sleeved on the extraction head 330.

[0048] In this embodiment, when the second connecting rod 324 moves under the driving force of the extraction pressure motor 310, it can drive the extraction head fixing bracket connecting rod 3251 to move, causing the upper end 3254 and the lower end 3253 of the extraction head fixing bracket to swing, thereby causing the extraction head 330 to move within the movement range between the initial position of the extraction head and the working position of the extraction base 360.

[0049] In specific implementation, when the extraction head 330 and the lower end 3253 of the extraction head fixing frame are connected to the extraction head 330, they can slide along the extraction head guide rail (which is a straight guide rail) set on the extraction device frame 300 to ensure that the extraction head 330 moves in a straight line along the extraction head guide rail.

[0050] More specifically, when the first photoelectric sensor 301a detects that the first sensing plate group 3231 has moved to the first position and generates a first sensing signal, both the upper end 3254 and the lower end 3253 of the extraction head holder swing to a swing angle of 0° (at this time, the swing angle is the angle between the upper end 3254 or the lower end 3253 of the extraction head holder and the vertical reference plane). When the second photoelectric sensor 301b detects that the first sensing plate group 3231 has moved to the second position and generates a second sensing signal, both the upper end 3254 and the lower end 3253 of the extraction head holder swing to a swing angle greater than 0°.

[0051] In one embodiment, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the second link structure 350 includes:

[0052] A transmission link structure 351 is connected at one end to the second rotating shaft. The transmission link structure 351 can move along the extraction base motion rail base 370, and the extraction base 360 ​​is engaged with the transmission link structure 351.

[0053] The second sensing element group 352 is disposed on one end of the transmission link structure 351 near the second rotating shaft.

[0054] The transmission link structure 351 includes:

[0055] A first side swing rod 3511 is provided on the side near the extraction base transmission motor 340; the top of the first side swing rod is provided with a first through groove (not shown in the figure);

[0056] A second side swing rod 3512 is provided on the side away from the extraction base transmission motor 340; the top of the second side swing rod is provided with a second through groove (not shown in the figure);

[0057] A first transverse connecting rod 3513, with one end fixed through the bottom end of the first side swing rod 3511 and connected to the second rotating shaft of the extraction base transmission motor 340, and the other end fixed to the bottom end of the second side swing rod 3512;

[0058] A second transverse connecting rod 3514, one end of which is fixed to the middle of the first side swing rod 3511 and the other end of which is fixed to the middle of the second side swing rod 3512; wherein, the end of the second transverse connecting rod 3514 fixed to the middle of the first side swing rod 3511 is lower than the first through groove, and the end of the second transverse connecting rod 3514 fixed to the middle of the second side swing rod 3512 is lower than the second through groove;

[0059] A first spring (not shown in the figure) is disposed in the first through groove on the first side swing rod;

[0060] A second spring (not shown in the figure) is disposed in the second through groove on the second side swing rod.

[0061] In this embodiment, the transmission linkage structure 351 is configured as described above, allowing it to move along the extraction base motion rail base 370 under the driving force of the extraction base transmission motor 340. Since the extraction base 360 ​​is connected to the second rotating shaft of the extraction base transmission motor 340 via the second linkage structure 350, the extraction base 360 ​​also moves along the extraction base motion rail base 370 when the transmission linkage structure 351 moves. This allows the beverage capsules at the processing position of the extraction base 360 ​​to move along the first motion rail group 371 of the extraction base to below the extraction head 330, or to move along the first motion rail group 371 of the extraction base away from the extraction head 330. When the beverage capsules at the processing position of the extraction base 360 ​​move along the first motion rail group 371 of the extraction base to below the extraction head 330, extraction processing can be performed; when the extraction base 360 ​​moves along the first motion rail group 371 of the extraction base to the end away from the extraction head 330, the beverage capsules can be thrown into the waste recycling bin.

[0062] In one embodiment, such as Figure 1 , Figure 5 and Figure 6 As shown, the extraction base motion track base 370 also includes:

[0063] The extraction base second motion rail group 372 is disposed below the first motion rail group of the extraction base; wherein, the second transverse connecting rod 3514 can slide along the extraction base second motion rail group 372;

[0064] A raised guide platform assembly is disposed on the inner wall of the extraction base motion rail base 370 and located between the first motion rail group 371 and the second motion rail group 372 of the extraction base; wherein, each raised guide platform in the raised guide platform assembly is provided with a concave guide groove on the side away from the first motion rail group of the extraction base.

[0065] The extraction base first motion rail group 371 includes a first side motion rail 3711 near the first side swing rod and a second side motion rail 3712 away from the first side swing rod 3511; both the first side motion rail 3711 and the second side motion rail 3712 include a horizontal part motion rail 371a and an annular part motion rail 371b.

[0066] The raised guide platform assembly includes a first raised guide platform 3731 on the side close to the first side swing rod 3511, and a second raised guide platform on the side away from the first side swing rod 3511 (not marked due to viewing angle, but the specific structure can be referred to the first raised guide platform 3731); wherein, the concave guide groove provided on the side of the first raised guide platform 3731 away from the first side motion rail 3711 is denoted as the first concave guide groove 3732, and the concave guide groove provided on the side of the second raised guide platform away from the second side motion rail is denoted as the second concave guide groove (not marked due to viewing angle, but the specific structure can be referred to the first concave guide groove 3732).

[0067] In this embodiment, the extraction base motion rail base 370 is configured as described above, which facilitates the extraction base 360 ​​to move along the extraction base motion rail base 370 when the transmission linkage structure 351 moves. This allows the beverage capsule on the processing position of the extraction base 360 ​​to move along the first motion rail group 371 of the extraction base to below the extraction head 330, or to move along the first motion rail group 371 of the extraction base to a position away from the extraction head 330.

[0068] Furthermore, the first side protruding guide platform 3731 and the second side protruding guide platform can lift the extraction base 360 ​​and guide it during the movement of the extraction base 360.

[0069] The reason why both the first side motion rail 3711 and the second side motion rail 3712 include a horizontal motion rail 371a and an annular motion rail 371b (wherein the annular motion rail 371b is the side of the first side motion rail 3711 or the second side motion rail 3712 away from the extraction head 330) is because the extraction base 360 ​​needs to flip over to throw material when it moves to the annular motion rail 371b. Setting the annular motion rail 371b as an annular track at a certain angle facilitates the flipping of the extraction base 360 ​​when it moves to the annular motion rail 371b.

[0070] In one embodiment, such as Figure 6As shown, the first-side concave guide groove 3732 includes a first horizontal portion 3732a of the concave guide groove and a first enlarged diameter portion 3732b of the concave guide groove located at the end of the first horizontal portion 3732a away from the extraction head 330; the second-side concave guide groove includes a second horizontal portion of the concave guide groove (not marked due to viewing angle) and a second enlarged diameter portion of the concave guide groove located at the end of the second horizontal portion of the concave guide groove away from the extraction head (not marked due to viewing angle); wherein, the inner diameter of the first enlarged diameter portion 3732b of the concave guide groove is greater than the width of the first horizontal portion 3732a of the concave guide groove, and the inner diameter of the second enlarged diameter portion of the concave guide groove is greater than the width of the second horizontal portion of the concave guide groove.

[0071] In this embodiment, the first side concave guide groove 3732 is configured to include a first horizontal portion 3732a and a first enlarged diameter portion 3732b of the concave guide groove, while the second side concave guide groove is configured to include a second horizontal portion and a second enlarged diameter portion of the concave guide groove. This is to facilitate the horizontal guiding function of the first horizontal portion 3732a and the second horizontal portion of the concave guide groove when the extraction base 360 ​​moves towards the direction close to the extraction head 330; it is also to facilitate the flipping guiding function of the first enlarged diameter portion 3732b and the second enlarged diameter portion of the concave guide groove when the extraction base 360 ​​moves away from the extraction head 330.

[0072] In one embodiment, such as Figure 1 and Figure 7 As shown, the extraction base 360 ​​includes:

[0073] Extract base 361; wherein, the extract base 361 is provided with a processing position 3611;

[0074] A base connecting rod assembly is formed by a first-side connecting rod 3621 located on the side of the extract base 361 near the extraction base transmission motor 340, and a second-side connecting rod 3622 located on the side of the extract base away from the extraction base transmission motor; wherein, one end of the first-side connecting rod 3621 passes through the first-side motion rail 3711 and can slide along the first-side motion rail 3711, and one end of the second-side connecting rod 3622 passes through the second-side motion rail 3712 and can slide along the second-side motion rail 3712; the top end of the first spring contacts the first-side connecting rod 3621, and the top end of the second spring contacts the second-side connecting rod 3622.

[0075] A base guide block assembly is formed by a base first side guide block 3631 disposed on the side of the extract base 361 near the extraction base transmission motor 340, and a base second side guide block 3632 disposed on the side of the extract base 361 away from the extraction base transmission motor 340; wherein the base guide block assembly is in contact with the outer wall of the raised guide platform assembly, and the base guide block assembly can slide along the raised guide platform assembly.

[0076] A base guide post assembly is formed by a first-side guide post 3641 disposed on the side of the extract base 361 near the extraction base transmission motor 340, and a second-side guide post 3642 disposed on the side of the extract base 361 away from the extraction base transmission motor 340; both the first-side guide post 3641 and the second-side guide post 3642 are adapted to the concave guide groove, and the first-side guide post 3641 can slide along the first-side concave guide groove 3732, and the second-side guide post 3642 can slide along the second-side concave guide groove.

[0077] Wherein, the first width corresponding to the first guide post 3641 of the base is greater than the first height corresponding to the first guide post 3641 of the base, the first height is less than or equal to the height of the first horizontal part 3732a of the concave guide groove, and the first width is less than or equal to the inner diameter of the first enlarged part 3732b of the concave guide groove; the second width corresponding to the second guide post 3642 of the base is greater than the second height corresponding to the second guide post 3642 of the base, the second height is less than or equal to the height of the second horizontal part of the concave guide groove, and the second width is less than or equal to the inner diameter of the second enlarged part of the concave guide groove.

[0078] In this embodiment, the extraction base 360 ​​is configured with the above-described structure, allowing it to slide flexibly on the extraction base motion rail base 370 and to rotate flexibly. The reason why the first height is less than or equal to the height of the first horizontal portion 3732a of the concave guide groove, and the first width is less than or equal to the inner diameter of the first enlarged diameter portion 3732b of the concave guide groove, is that when the first side guide post 3641 of the base moves to the annular portion motion rail 371b in the first side motion rail 3711, the first side guide post 3641 of the base needs to rotate along with the extraction base 360. If the first enlarged diameter portion 3732b of the concave guide groove (or the second enlarged diameter portion of the concave guide groove) and the corresponding shape of the first side guide post 3641 of the base (or the second side guide post 3642 of the base) are not provided at this time, it will cause jamming during the rotation process, preventing the material from being ejected.

[0079] Furthermore, when the extraction base 360 ​​moves from a horizontal state to a flipped state, the first spring is compressed by the first side connecting rod 3621 of the base, and the second spring is compressed by the second side connecting rod 3622 of the base. When the extraction base 360 ​​moves from a flipped state to a horizontal state, the first and second springs, needing to recover their deformation, provide elastic force to the first side connecting rod 3621 and the second side connecting rod 3622 of the base on the extraction base 360, making the process of the extraction base 360 ​​moving from a flipped state to a horizontal state easier.

[0080] In one embodiment, such as Figure 1 and Figure 5 As shown, the extraction device frame 300 is further equipped with a third photoelectric sensor 302a, a fourth photoelectric sensor 302b, and a fifth photoelectric sensor 302c. The position of the third photoelectric sensor 302a on the extraction device frame 300 is designated as the third position, the position of the fourth photoelectric sensor 302b on the extraction device frame 300 is designated as the fourth position, and the position of the fifth photoelectric sensor 302c on the extraction device frame 300 is designated as the fifth position. The third photoelectric sensor 302a generates a third sensing signal when it detects that the second sensing plate group 352 has moved to the third position, the fourth photoelectric sensor 302b generates a fourth sensing signal when it detects that the second sensing plate group 352 has moved to the fourth position, and the fifth photoelectric sensor 302c generates a fifth sensing signal when it detects that the second sensing plate group 352 has moved to the fifth position.

[0081] When the third photoelectric sensor 302a detects that the second sensing plate group 352 has moved to the third position, the end of the transmission link structure 351 away from the extraction base transmission motor 340 moves to the end of the horizontal motion rail 371a near the extraction head 330; when the fourth photoelectric sensor detects that the second sensing plate group 352 has moved to the fourth position, the end of the transmission link structure 351 away from the extraction base transmission motor moves to the end of the horizontal motion rail 371a away from the extraction head 330, and the end of the transmission link structure 351 away from the extraction base transmission motor 340 is located at the starting end of the annular motion rail 372a; when the fifth photoelectric sensor detects that the second sensing plate group has moved to the fifth position, the end of the transmission link structure away from the extraction base transmission motor 340 is located at the ending end of the annular motion rail 372a.

[0082] In this embodiment, when the second sensing plate group 352 moves to the third position, the corresponding processing position 3611 is located below the extraction head 330, that is, the processing position 3611 is in the extraction position at this time; when the second sensing plate group 352 moves to the fourth position, the corresponding processing position 3611 has moved away from the extraction head 330 and the processing position 3611 is below the storage device storing beverage capsules in the smart vending device, that is, the processing position 3611 is in the capsule dropping position at this time; when the second sensing plate group 352 moves to the fifth position, the corresponding processing position 3611 is in the flipped state, that is, the processing position 3611 is in the capsule discarding position at this time. Therefore, during one extraction process, the processing position 3611 first stays in the capsule dropping position, moves to the extraction position after receiving the dropped beverage capsule, and finally moves to the capsule discarding position after completing the extraction process. After completing the capsule discarding, it returns to the capsule dropping position until the next extraction process begins.

[0083] Furthermore, the first spring and the second spring are provided in the transmission linkage structure 351 to provide elastic force during the process of the extraction base 360 ​​flipping and resetting (i.e., restoring the movement from the capsule throwing position to the capsule dropping position), so that the flipping and resetting process of the extraction base 360 ​​is not easily jammed.

[0084] In one embodiment, such as Figure 1 , Figure 2 ,and Figure 5 As shown, the extraction device frame 300 is also provided with an annular channel 303 on the side near the extraction head 330, and the annular channel 303 is located above the extraction base 360; it also includes a feeding rod 304 with one end connected to a fixing plate 3031 on the outer wall of the annular channel 303, and the feeding rod 304 can rotate around the fixing plate 3031; it also includes a baffle 305 fixedly installed on the extraction device frame 300 and located on the side of the extraction base 360 ​​away from the extraction head 330.

[0085] In one embodiment, an annular channel 303 is provided on the side of the extraction device frame 300 near the extraction head 330 to facilitate the guidance of the beverage capsules as they fall from the storage device containing the beverage capsules in the smart vending device to the processing position 3611, thereby preventing them from deviating.

[0086] A feeding rod 304 is connected to a fixed plate 3031 on the outer wall of the annular channel 303. Its function is to apply external force to the beverage capsules that failed to be thrown at the processing position 3611, so that the beverage capsules can successfully fall off the processing position 3611. As the extraction base 360 ​​moves from the extraction position to the capsule throwing position, it will flip, which will cause the feeding rod 304 to swing together. When the extraction base 360 ​​flips and moves to the end of the transmission linkage structure 351 away from the extraction base transmission motor 340, which is located at the end of the annular movement rail 372a, the beverage capsules that failed to be thrown at the processing position 3611 have not fallen into the waste recycling bin. At this time, when the extraction base 360 ​​moves back to the capsule dropping position, the bottom end of the feeding rod 304 moves along the outer wall of the beverage capsule until it abuts the top of the beverage capsule, causing it to fall off the processing position 3611 into the waste recycling bin.

[0087] A baffle 305 is also provided on the frame 300 of the extraction device and on the side of the extraction base 360 ​​away from the extraction head 330. This is to prevent the beverage capsule from moving too far after being thrown. By blocking it, the beverage capsule bounces off the baffle and falls into the waste recycling bin.

[0088] This invention provides an extraction device in which an extraction pressure motor drives an extraction head downward to a processing position via a first linkage structure to extract beverage capsules at the processing position. After extraction, an extraction base transmission motor drives the extraction base away from the extraction head via a second linkage structure, thereby achieving material discharge.
