Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and in particular to a roller-type multi-functional capsule coffee machine with large capacity. Background Technology

[0002] Capsule coffee machines are a type of coffee machine that makes coffee extraction simpler and more convenient. To operate the machine, simply insert a coffee capsule into the capsule compartment, and coffee is extracted with a single touch. Compared to semi-automatic or fully automatic coffee machines that use ground coffee, this is much simpler to use. Capsule coffee machines work by having manufacturers pre-fill plastic capsules with ground coffee and then filling them with nitrogen to preserve freshness. When you want to drink coffee, simply insert the capsule into the dedicated machine, and you can quickly enjoy a cup of aromatic coffee.

[0003] Structurally, existing capsule coffee machines use a single or single-row partition or cabinet to store coffee capsules. When brewing is needed, the capsules are pushed out by built-in mechanical grippers or multi-axis guide rails, and finally extracted into a cup by the extraction mechanism.

[0004] However, these traditional capsule machines can only hold a small number of coffee capsules at a time. If used as commercial self-service machines, maintenance personnel need to frequently refill the capsules. In addition, single-use, single-head extraction machines can only dispense one cup of coffee per extraction (which also involves removing waste capsules), and subsequent capsules enter a long queue. Therefore, brewing efficiency is also a problem that urgently needs to be solved.

[0005] In view of this, this technical solution proposes a roller-type multi-functional capsule coffee machine with large capacity. It adopts a rotatable roller structure to hold more capsules, achieving all-weather maintenance-free operation. Combined with a double-sided gripper mechanism with automatic rotation, it can achieve a fast double-cup dispensing effect and shorten the waiting time. Utility Model Content

[0006] The present invention aims to at least partially solve one of the technical problems in the related art. Therefore, the main objective of this invention is to provide a roller-type multi-functional capsule coffee machine with large capacity, addressing the issues of low dispensing efficiency, limited capsule capacity, and frequent maintenance required by traditional capsule coffee equipment in the prior art.

[0007] To achieve the above objectives, this utility model provides a roller-type multi-functional capsule coffee machine with large capacity, comprising a cabinet, an internal cup holder, an extraction mechanism, a roller-type feeding assembly, an electrical control unit, and a feeding transfer assembly, forming the capsule machine body.

[0008] The cup holder is disposed between the roller loading assembly and the extraction mechanism body. The roller loading assembly includes a vertically placed cylindrical roller body. A motor is located at the bottom of the roller body, and vertically arranged limiting frames are provided on the surface of the roller body. The limiting frames limit the two sides of the capsules placed inside. Near the bottom of the limiting frames, there are tumblers for ejecting the capsules. A tumbler drive is connected to the rear end of the tumblers, located inside the roller body.

[0009] The material transfer assembly includes a material discharge extraction position located below the roller loading assembly and the main body of the extraction mechanism. The extraction head of the extraction mechanism is directly above the material discharge extraction position. An openable clamping frame is provided outside the material discharge extraction position. A first material picking head and a second material picking head are respectively provided on both sides of the bottom of the material discharge extraction position. The first material picking head and the second material picking head are respectively connected to a first rotating mechanism and a second rotating mechanism. The material transfer assembly moves back and forth at the bottom of the extraction mechanism main body and the roller loading assembly via a lead screw.

[0010] As a further embodiment of this utility model, the cabinet is provided with an automatic compartment door at the facing end, and a cup holder connected to a slide is provided at the bottom rear of the automatic compartment door. The bottom of the slide is set on a guide rail in the X-axis direction.

[0011] As a further embodiment of this utility model, the first rotating mechanism and the second rotating mechanism are resettable rotating mechanisms that combine gears and cams.

[0012] As a further embodiment of this utility model, the roller loading assembly also includes a bottom frame located at the bottom end of the limiting frame. The bottom frame is an upward-opening arc-shaped frame, and the opening contour corresponds to the outer contour of the capsule.

[0013] As a further embodiment of this utility model, the top of the material transfer assembly is framed by an outer frame, and the two ends of the lead screw pass through the two ends of the outer frame via movable bushings.

[0014] As a further improvement of this utility model, the cabinet is also equipped with a milk foaming mechanism.

[0015] As a further improvement of this utility model, the bottom of the material transfer assembly is provided with a waste bin.

[0016] As a further improvement of this utility model, a cover area is provided on one side of the exterior of the cabinet.

[0017] As a further improvement of this invention, the number of cup holders is at least four.

[0018] The beneficial effects of this utility model are as follows:

[0019] This technical solution utilizes vertically arranged limiting frames on the roller body surface, combined with a bottom frame structure, to increase capsule capacity several times over and achieve precise dispensing via ball-driven mechanisms, significantly reducing maintenance frequency. The dispensing assembly employs a screw-driven dual-station system, with the first and second dispensing heads operating synchronously via a gear-cam rotary mechanism. After extraction at the dispensing extraction station, the second dispensing head immediately removes the waste capsule cap to the waste bin, while the first dispensing head pours the coffee liquid into cups on the cup holder, achieving synchronous circulation, shortening single-cup preparation time, and supporting continuous double-cup dispensing. Overall, this solution is based on the large-capacity roller feeding system, with efficient dispensing via dual dispensing heads as its core, supplemented by automatic waste bin collection, multi-cup holder circulation, milk frothing, and capping value-added functions, forming a commercial-grade capsule coffee solution. While maintaining 24 / 7 maintenance-free operation, it improves dispensing efficiency and expands beverage diversity. Attached Figure Description

[0034] as follows:

[0035] Please see the appendix Figure 1-11 ,

[0036] The capsule coffee machine of this technical solution consists of a cabinet (10), a cup holder (12), an extraction mechanism (13), a roller loading assembly (16), an electrical control unit (18), and a material transfer assembly (19). The cup holder (12) is located between the roller loading assembly (16) and the extraction mechanism body (13). The roller loading assembly (16) includes a vertically placed cylindrical roller body (161), with a motor (160) installed at the bottom to drive its rotation. A series of vertically arranged limiting frames (162) are provided on the surface of the roller body (161). These limiting frames (162) can firmly limit the two sides of the capsule (2), allowing the capsule (2) to move downward only when it needs to work. Each limiting frame (162) is provided with a ball (1620) near the bottom. The rear end of the ball (1620) is connected to the ball drive (1621) inside the roller body (161). When the capsule (2) moves to the bottom of the limiting frame (162), the ball drive (1621) will drive the ball (1620) to quickly eject the capsule (2). The material transfer assembly (19) is located below the roller loading assembly (16) and the main body of the extraction mechanism (13). It includes a material dropping extraction position (193). The material dropping extraction position (193) is directly aligned with the extraction head of the main body of the extraction mechanism (13). The material dropping extraction position (193) is equipped with an openable clamping frame (191) for fixing its position. A first material picking head (194) and a second material picking head (196) are respectively set on both sides of the bottom of the material dropping extraction position (193). The first material picking head (194) is connected to the first rotating mechanism (195), and the second material picking head (196) is connected to the second rotating mechanism (197). The entire material transfer assembly (19) moves back and forth at the bottom of the main body of the extraction mechanism (13) and the roller loading assembly (16) through a lead screw to achieve precise displacement.

[0037] Specifically, the cylindrical structure of the roller body (161) can accommodate more capsules (2) than the traditional box-shaped design. Combined with the vertical arrangement of the limiting frame (162) and the ejection mechanism of the ball (1620), the capsules (2) are efficiently transported to the extraction position (193) for extraction, greatly reducing the frequency of manual addition of capsules (2). The dual-head design of its transfer component (19) allows the second head (196) to quickly remove and discard the waste capsule cap through the second rotating mechanism (197), while the first head (194) moves the capped coffee to the dispensing position through the first rotating mechanism (195). With the flexible displacement driven by the screw, multiple actions can be performed synchronously and cyclically, avoiding queuing for single extraction, thereby greatly improving the dispensing efficiency, achieving a fast double dispensing effect, shortening the user's waiting time, and solving the problems of slow dispensing, low capsule (2) loading, and frequent maintenance of traditional equipment. The entire system operates smoothly without frequent intervention and is suitable for commercial self-service scenarios.

[0038] Reference Appendix Figure 2In a preferred embodiment of this utility model, the capsule machine designed in this scheme has a cup compartment structure with an automatic compartment door (14). The cup compartment is located at the front of the cabinet (10) and is used to stack cups. The compartment door in front of it can be opened and closed automatically, and the opening and closing is controlled by the drive device connected to it. A cup clamp (130) is provided below the cup compartment, which is used to automatically and securely clamp the cup when it needs to be taken out. The bottom of the cup clamp (130) is connected to a movable slide (131). The slide (131) moves along the guide rail (132) set horizontally along the X-axis, so as to smoothly transport the clamped cup from the cup compartment position to the cup dispensing position outside the cabinet (10), realizing the fully automated cup taking and cup delivery process.

[0039] Specifically, when the user gives the instruction, the compartment door will open automatically, and the cup clamp (130) mechanism will automatically clamp the cup at the bottom of the cup compartment. Then, the slide (131) will immediately drive the cup clamp (130) to move steadily along the guide rail (132) in the X-axis direction until it reaches the designated external position. Only then will the cup clamp (130) release the cup for the user to take. This avoids the steps of manually taking and placing the cup required by the traditional machine. At the same time, the stable clamping of the cup clamp (130) and the smooth movement of the slide (131) ensure that the cup conveying process is safe, reliable and does not spill. This improves the automation level and ease of operation of the whole machine. Especially during continuous cup dispensing or peak periods, it can seamlessly connect the coffee extraction and cup dispensing actions.

[0040] Reference Appendix Figure 10 , 11 In a preferred embodiment of this utility model, the first rotating mechanism (195) and the second rotating mechanism (197) of this solution can be resettable rotating mechanisms with gears and cams. When the first picking head (194) and the second picking head (196) perform actions, they can achieve stable and controllable rotational motion through the precise cooperation of gears and cams. After completing the action (such as picking up waste capsule caps or pouring coffee powder), they can automatically and accurately reset to the initial position, ensuring the consistency of each action, improving the efficiency of the material transfer component (19), avoiding jamming or deviation during the action of the picking head, ensuring the success rate of picking up waste capsule caps and pouring coffee powder, and at the same time, the reset function prepares for the continuous and rapid next round of picking and transferring actions, seamlessly connecting the feeding rhythm of the roller, and the circulation speed is fast and smooth.

[0041] Reference Appendix Figure 7 , 9 In a preferred embodiment of the present invention, a bottom frame (164) structure is provided at the bottom of the limiting frame (162). The bottom frame (164) is an arc-shaped frame with an upward opening, and its opening contour is completely matched with the external shape of the capsule (2). It is mainly used for attitude correction during the descent of the capsule (2).

[0042] In practice, when the ball drive (1621) ejects the capsule (2) from the bottom of the limiting frame (162), the capsule (2) will naturally fall into the lower arc-shaped bottom frame (164). The arc surface of the bottom frame (164) will guide the capsule (2) to slide along a specific trajectory and automatically adjust to a positive posture, ensuring that the capsule (2) always maintains a vertical and centered ideal position in the material extraction position (193), further improving the overall efficiency.

[0043] Reference Appendix Figure 10 , 11 In a preferred embodiment of this utility model, an outer frame (198) is provided outside the material assembly, and the two ends of the lead screw (192) that drives the displacement assembly (19) pass through the movable bushings on both sides of the outer frame (198). The frame structure of the outer frame (198) provides support for the material assembly (19), limiting the vibration or offset generated by the first picking head (194) and the second picking head (196) during high-speed rotation and movement. The lead screw (192) is flexibly connected to the outer frame (198) through the movable bushing, ensuring that the lead screw (192) moves back and forth along the guide rail (132) when driving the material assembly (19). The material extraction position (193) remains stable during movement. The first picking head (194) and the second picking head (196) can accurately perform the actions of clamping and pouring capsules (2) or waste caps, reducing the slippage of capsules (2) and material misalignment caused by mechanical vibration.

[0044] Reference Appendix Figure 2 , 3 In a preferred embodiment of this utility model, the capsule machine is also equipped with an independent milk foaming mechanism (17). This mechanism is connected to the milk storage container through an independent pipeline and is equipped with a dedicated steam generator and milk foam nozzle. This technical solution, while maintaining the core advantages of the roller capsule coffee machine in terms of large capacity and high efficiency, significantly expands the diversity of beverage preparation. That is, the milk foaming mechanism (17) can be automatically started during or after the capsule coffee extraction process. The steam generator heats the milk and froths it into dense milk foam, which is then precisely injected into the cup by the milk foam nozzle. Users can make milk-containing coffee drinks such as cappuccino and latte with one click without additional equipment.

[0045] Reference Appendix Figure 2 In a preferred embodiment of this utility model, a waste bin (15) structure is provided directly below the transfer component (19). The waste bin (15) directly receives the waste capsule caps thrown down by the second material receiving head (196) during its rotation. The top of the waste bin is designed to accurately receive the falling waste caps, and the bottom is provided with a horizontally pull-out collection compartment. The side is equipped with buckles for fixing and snapping, thus realizing the automated centralized processing and efficient cleaning of waste.

[0046] Reference Appendix Figure 2In a preferred embodiment of this utility model, the capsule machine of this solution also adds a capping area (11) on the outside of the cabinet (10). This area is equipped with an automatic capping device, which is connected to the end of the cup dispensing path of the cup holder (12). When the cup clamp (130) sends the cup containing coffee to the capping area (11) along the guide rail (132) through the slide (131), the capping device can automatically identify the position of the cup mouth and complete the precise locking and sealing of the cup lid, realizing the full closed-loop automation of the beverage dispensing process. Users do not need to manually put on the cup lid. After the cup clamp (130) transports the extracted coffee cup to the capping area (11), the capping device immediately acts and automatically locks the pre-set cup lid on the cup mouth through the mechanical clamp arm or negative pressure suction cap mechanism. No manual intervention is required throughout the process, avoiding the problem of hot drinks burning hands and spillage. It is especially suitable for self-service scenarios such as shopping malls and office areas where people need to pick up and leave immediately.

[0047] Reference Appendix Figure 2 , 3 In a preferred embodiment of this utility model: Preferably, the number of cup holders (12) in this solution is at least 4, which improves the continuous cup dispensing capacity of the equipment. Multiple cup holders (12) form a circular queue, so that after the first feeding head (194) pours out the coffee powder, it can quickly move the empty cup to the idle cup holder (12) for temporary storage. At the same time, the second feeding head (196) can simultaneously transfer the extracted coffee cup to the waiting area. In practice, when the user takes away the finished product, the cup clamp (130) can immediately retrieve a new cup from the spare cup holder (12) to replenish the extraction station, realizing the rapid cycle of roller feeding, double feeding head material transfer, cup holder (12) buffering, and cup dispensing process.

[0048] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the present utility model's technical concept and the contents of the present utility model's technical solution specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
