Description

Technical Field

[0001] The present invention relates to a beverage vending machine, and more particularly to a capsule conveying structure of a beverage intelligent extraction machine. Background Art

[0002] A beverage extraction machine based on beverage capsules is an extraction device that extracts corresponding juices from the contents in a container by quickly heating water under high pressure. It is suitable for processing containers (capsules) packed with ingredients. After the ingredients interact with a liquid such as hot pressurized water introduced into the capsule, beverages or edible juices can be produced. The capsule is a frustum-shaped ring, and ingredients such as coffee powder, tea leaves or the like can be filled in the ring. It is closed by a foil tearing surface cover welded or crimped on a ring-shaped edge radially extending from the side wall of the ring. A common extraction machine is a capsule coffee machine. The technology of capsule coffee machines has been relatively mature, but it can only be used at home. Each time coffee is prepared, first take out the capsule from the packaging box, pull the handle to open the coffee machine, manually insert a coffee capsule, then pull the handle again to close the mechanism, and the machine starts to extract the beverage. After the extraction is completed, pull the handle again to remove the capsule. Existing coffee machines cannot achieve the function of automatic vending.

[0003] Existing beverage vending machines are not machine devices based on beverage capsules.

[0004] For this reason, the applicant has applied for a Chinese utility model patent "Intelligent Beverage Extraction Machine Based on Beverage Capsules" with the patent number ZL201920574008.7 (publication number CN210276889U). It discloses a capsule conveying structure. The beverage capsule falls out from the capsule drop outlet below the capsule storage rack and enters the storage hole of the capsule transition storage device. The pre-positioning structure locks the beverage capsule in the storage hole. When the pre-positioning structure is in the released positioning state, the beverage capsule falls out from below the storage hole and is received by the capsule conveying device below. That is, the ring-shaped edge of the beverage capsule is placed on the two slide rails of the capsule conveying device. The first belt drive structure acts, and the pushing member moves along with the first transmission belt to push the beverage capsule forward along the slide rail until the beverage capsule falls into the concave cavity of the capsule receiving cup.

[0005] The foregoing extraction machine also has the following defects:

[0006] 1. The beverage capsule that falls out from below the storage hole needs to be conveyed to the front end by the foregoing conveying structure before it can enter the concave cavity of the capsule receiving cup, and the capsule receiving cup then slides left and right to complete the extraction, with a complex structure.

[0007] 2. After the gear structure is released, the lower ports of each capsule receiving groove are all in an open state, and the weights of all the beverage capsules on each capsule receiving groove are all accumulated and act on the capsule located in the storage hole, resulting in the pre-positioning structure being unable to firmly lock the beverage capsule in the storage hole, and it is easy to have the situation of dropping multiple beverage capsules at once.

[0008] Therefore, the capsule storage rack structure of the aforementioned patent still needs further improvement. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to provide a capsule conveying structure for a beverage intelligent extraction machine with a more reasonable structural layout in view of the current situation of the above-mentioned prior art.

[0010] The technical solution adopted by the present invention to solve the above technical problem is as follows: A capsule conveying structure for a beverage intelligent extraction machine, including a capsule storage rack, on the end face of the capsule storage rack, there are provided a plurality of capsule accommodation grooves that are spaced front and rear and vertically penetrate. Each capsule accommodation groove can sequentially place a plurality of beverage capsules that can slide up and down relative to the capsule accommodation groove from top to bottom. On the front and rear side walls of the capsule accommodation groove, there are provided chutes for inserting the annular edges of the beverage capsules, and the bottom of the capsule accommodation groove is open for the beverage capsules to fall out; a capsule transition storage rack is provided below the capsule storage rack, and a plurality of storage holes corresponding to the bottom openings are provided on the capsule transition storage rack. In each storage hole, there is a pre-positioning structure for restricting the beverage capsules; it is characterized in that: it further includes a capsule receiving cup that moves along a track below the capsule transition storage rack. The capsule receiving cup can be driven by a first driving structure to move back and forth, and the capsule receiving cup has a concave cavity for receiving the capsules; a plurality of guiding structures corresponding to the storage holes one by one are provided below the capsule transition storage rack. In the state where the capsule receiving cup moves to a position corresponding to one of the storage holes, the beverage capsules falling from the storage hole can be guided to the concave cavity of the capsule receiving cup through the guiding structure at the corresponding position.

[0011] For further improvement, below each capsule accommodation groove, there is a blocking column that can be driven by a second driving structure to quickly extend and retract; in the state where the blocking column extends out, the blocking column blocks the annular edge of the lowermost beverage capsule located in the capsule accommodation groove to prevent the beverage capsule from passing downward through the bottom opening; in the state where the blocking column retracts, the blocking column releases the blocking of the annular edge of the lowermost beverage capsule. After the lowermost beverage capsule falls downward, the second driving structure drives the blocking column to quickly extend out to block the next beverage capsule located at the lowermost position.

[0012] Below each capsule accommodation groove, there is a blocking column that can be quickly telescoped by a second driving structure. During operation, the blocking column quickly retracts, and the lowermost beverage capsule drops downward and passes through the bottom opening of the capsule accommodation groove. After that, the second driving structure drives the blocking column to quickly extend outward to block the next beverage capsule located at the lowermost position, effectively ensuring that only one capsule drops at a time. At the same time, the capsules located in the capsule accommodation groove are prevented from exerting a downward pressure on the beverage capsules that have dropped or are about to drop onto the capsule transition storage rack, thus effectively preventing multiple beverage capsules from falling out of the capsule transition storage rack.

[0013] Preferably, the second driving structure is a first solenoid iron. The blocking column is connected to the iron core of the first solenoid iron so as to move along with the iron core. When the first solenoid iron is energized, the iron core of the first solenoid iron drives the blocking column to retract. When the first solenoid iron is de-energized, the iron core of the first solenoid iron drives the blocking column to extend outward. Using the first solenoid iron as the second driving structure is conducive to control. Through programming, the first solenoid iron can be quickly de-energized and energized, and then the telescoping of the blocking column can be quickly controlled. An installation box is fixed to the rear of the capsule storage rack, and each of the first solenoid irons is installed in the installation box at intervals. During assembly, the first solenoid irons can be pre-assembled into the installation box, and then the blocking column can be connected to the first solenoid iron to form an independent module, and then the installation box can be fixed to the back of the capsule storage rack to complete the assembly.

[0014] Further improvement: A plurality of through holes are formed on the surface of the capsule storage rack. The through holes correspond to one of the sliding grooves on the capsule accommodation groove, and each through hole is correspondingly provided with a blocking column. This can hide the blocking column inside the sliding groove and avoid exposure.

[0015] Due to the certain weight of the beverage capsule, the beverage capsule placed from above the capsule accommodation groove will quickly move downward, which will form a large impact force on the blocking column and is likely to damage the blocking column. To solve this technical problem, further improvement: A clamping plate that can slide back and forth relative to the capsule storage rack is provided at the bottom of the capsule storage rack. The clamping plate is located below the capsule accommodation groove, and a plurality of supporting portions for supporting the body of the lowermost beverage capsule are provided at intervals on the clamping plate. The clamping plate has two position states. During the process of loading beverage capsules, the clamping plate moves to the first position state, and each supporting portion simultaneously supports the body of the lowermost beverage capsule in each capsule accommodation groove. During operation, the clamping plate moves to the second position state, and each of the supporting portions simultaneously releases the support for the body of the lowermost beverage capsule in each capsule accommodation groove.

[0016] When placing the beverage capsule, the pallet moves to the first position state, and each support portion simultaneously supports the body of the lowermost beverage capsule in each capsule receiving groove. The beverage capsules entering the capsule receiving grooves will be simultaneously supported by the support portions, greatly reducing the impact on the blocking columns, thereby effectively preventing the downward-moving beverage capsules from damaging the blocking columns or the notches of the driving structure. During normal operation, when the pallet moves to the second position state, each support portion simultaneously releases the support on the body of the lowermost beverage capsule in each capsule receiving groove, without affecting the downward passage of the beverage capsules through the bottom opening of the capsule receiving groove.

[0017] To facilitate the assembly of the capsule storage rack and the formation of the chute, the above-mentioned capsule storage rack includes a base plate. A plurality of strip-shaped profiles are detachably fixed on the front end surface of the base plate at intervals in the front-rear direction. The side of the profile has an L-shaped folded edge. The two folded edges that are spaced apart from each other in adjacent profiles and the front end surface of the base plate together form the capsule receiving groove.

[0018] For further improvement, the above-mentioned pre-positioning structure includes a positioning block, which can slide left and right under the push of a second solenoid iron provided in the capsule transition storage rack. A through hole for the positioning block to enter and exit is opened on the inner hole wall of the storage hole; in the state where the positioning block extends into the storage hole through the through hole, the positioning block forms a block on the annular edge of the beverage capsule that is about to slide into the storage hole but is still located in the capsule receiving groove, realizing positioning; in the state where the positioning block exits the storage hole through the through hole, the positioning block no longer forms a block on the annular edge of the beverage capsule, releasing the positioning. The beverage capsule that is about to fall out of the storage hole is jointly affected by the positioning block and the chute on the capsule receiving groove for the annular edge of the beverage capsule to be inserted, and the beverage capsule is transitionally stored on the capsule transition storage rack, so that the beverage capsule will not immediately fall out of the storage hole. When the positioning block retracts, the beverage capsule will then fall out of the storage hole onto the guiding structure.

[0019] To achieve automatic and precise control of the dropping of the beverage capsule from the capsule receiving groove, a detection switch for detecting whether the body of the beverage capsule enters therein is provided on the side wall of the above-mentioned storage hole. Since a part of the body of the beverage capsule enters the storage hole, the detection switch will detect it, and the detection switch will give a signal to control whether the capsule drops from the corresponding capsule receiving groove on the capsule storage rack.

[0020] Preferably, the above-mentioned first driving structure is a belt drive structure with a stepping motor as the driving source. The capsule receiving cup is fixed on the transmission belt of the belt drive structure. The belt drive structure is arranged on the installation track, and a guide rail extending along the preset track direction is further provided on the installation track. A guide wheel cooperating with the guide rail is provided on the capsule receiving cup. The stepping motor can effectively control the number of rotation turns of the stepping motor, that is, it can precisely control the sliding stroke of the capsule receiving cup. The setting of the guide wheel and the guide rail can make the sliding of the mounting seat easy and with little resistance.

[0021] Preferably, each of the guiding structures includes two guiding inclined plates fixed below the capsule transition storage rack. The two guiding inclined plates are arranged at the front and rear sides below the storage holes at intervals. The distance between the two guiding inclined plates satisfies the following condition: the annular edge of the beverage capsule falling from the storage hole is placed on the top inclined surfaces of the two guiding inclined plates, and the body of the beverage capsule is located within the distance between the two guiding inclined plates. When the capsule receiving cup moves to a position corresponding to one of the storage holes, the end of the guiding inclined plate at this position is located above the concave cavity of the capsule receiving cup. The aforementioned guiding structure is simple and reasonable. The guiding inclined plates have a constraining effect on the sliding of the beverage capsule, ensuring that it slides obliquely along a predetermined trajectory. The inclination angle should be appropriate. If it is too large, the downward inertia of the beverage capsule is large; if it is too small, the beverage capsule cannot slide smoothly.

[0022] Compared with the prior art, the advantages of the present invention are as follows: After the beverage capsule in this application falls from the capsule storage rack to the capsule transition storage rack and then falls out of the capsule transition storage rack, it directly falls into the concave cavity of the capsule receiving cup via the guiding structure. The capsule receiving cup is driven by the first driving structure and can move back and forth, that is, in the same direction as the arrangement direction of the capsule accommodating grooves in the capsule storage rack, so as to realize extraction and de-capsulation in the front-back movement direction of the capsule receiving cup. Therefore, compared with the previous generation design, the conveying structure is omitted, and at the same time, the capsule extraction device and the de-capsule structure can be arranged in the front-back direction, thereby making the layout of the entire beverage intelligent extraction machine more reasonable and compact.

[0033] The present invention will be further described in detail below in conjunction with the embodiments with reference to the accompanying drawings.

[0034] As Figures 1 to 10 shown, it is a preferred embodiment of the present invention.

[0035] A capsule conveying structure of a beverage intelligent extraction machine, comprising

[0036] A capsule storage rack 1. In this embodiment, there are two sets of capsule storage racks 1. A plurality of capsule accommodation grooves 2 are provided on the end surface of the capsule storage rack 1 at intervals in the front-back direction and vertically penetrating. Each capsule accommodation groove 2 can successively place a plurality of beverage capsules 4 that can slide up and down relative to the capsule accommodation groove 2 from top to bottom. Sliding grooves 22 for inserting the annular edges 41 of the beverage capsules 4 are formed on the front and rear side walls of the capsule accommodation groove 2, and the bottom opening 21 of the capsule accommodation groove 2 allows the beverage capsules 4 to fall out. The capsule storage rack 1 includes a base plate 11. A plurality of strip-shaped profiles 12 are detachably fixed on the front end surface of the base plate 11 at intervals in the front-back direction. The side of the profile 12 has an L-shaped folded edge 121. The two folded edges 121 that are spaced apart from each other in two adjacent profiles 12 and the front end surface of the base plate 11 together form the capsule accommodation groove 2.

[0037] A blocking column 3 that can be quickly extended and retracted by a second driving structure is provided below each capsule accommodation groove 2; in the state where the blocking column 3 extends out, the blocking column 3 blocks the annular edge 41 of the lowermost beverage capsule 4 located in the capsule accommodation groove 2 to prevent the beverage capsule 4 from passing downward through the bottom opening 21; in the state where the blocking column 3 retracts, the blocking column 3 releases the blocking of the annular edge 41 of the lowermost beverage capsule 4. After the lowermost beverage capsule 4 falls downward, the second driving structure drives the blocking column 3 to quickly extend out to block the next beverage capsule 4 located at the bottom.

[0038] The second driving structure is the first solenoid iron 5. The first solenoid iron 5 generally includes components such as a coil, an iron core 51, and a spring, and it has a conventional structure. The blocking column 3 is connected to the iron core 51 of the first solenoid iron 5 so as to move with the iron core 51. When the first solenoid iron 5 is energized, the iron core 51 of the first solenoid iron 5 drives the blocking column 3 to retract. When the first solenoid iron 5 is de-energized, the iron core 51 of the first solenoid iron 5 drives the blocking column 3 to extend. An installation box 6 is fixed to the rear part of the capsule storage rack 1, and the first solenoid irons 5 are spaced apart and installed in the installation box 52.

[0039] A plurality of through holes 111 are formed on the surface of the capsule storage rack 1, and the through holes 111 correspond to one of the sliding grooves 22 on the capsule accommodation groove 2. Each through hole 111 is correspondingly provided with a blocking column 3 inserted therein.

[0040] A clamping plate 7 capable of sliding back and forth relative to the capsule storage rack 1 is provided at the bottom of the capsule storage rack 1. The clamping plate 7 is located below the capsule accommodation groove 2, and a plurality of supporting parts 71 for supporting the body of the lowermost beverage capsule 4 are provided at intervals on the clamping plate 7. The clamping plate 7 has two position states. During the process of loading the beverage capsules 4, the clamping plate 7 moves to the first position state, and each of the supporting parts 31 simultaneously supports the body of the lowermost beverage capsule 4 in each capsule accommodation groove 2. During the working process, the clamping plate 7 moves to the second position state, and each of the supporting parts 71 simultaneously releases the support for the body of the lowermost beverage capsule 4 in each capsule accommodation groove 2.

[0041] A capsule transition storage rack 6 is provided below the capsule storage rack 2. A plurality of storage holes 61 corresponding to the bottom openings 21 are formed on the capsule transition storage rack 6, and a pre-positioning structure for limiting the beverage capsule 4 is provided in each storage hole 61.

[0042] The pre-positioning structure includes a positioning block 91, which can slide left and right under the push of a second solenoid iron 9 provided in the capsule transition storage rack 3. A through opening 62 for the positioning block 91 to enter and exit is formed on the inner hole wall of the storage hole 61. In the state where the positioning block 91 extends into the storage hole 61 through the through opening 62, the positioning block 91 blocks the annular edge 41 of the beverage capsule 4 that is about to slide into the storage hole 61 but is still located in the capsule accommodation groove 2, realizing positioning. In the state where the positioning block 91 withdraws from the storage hole 61 through the through opening 62, the positioning block 91 no longer blocks the annular edge 41 of the beverage capsule 4, releasing the positioning. A detection switch 63 for detecting whether the body of the beverage capsule 4 enters therein is provided on the side wall of the storage hole 61.

[0043] A capsule receiving cup 8 that moves along a track below the capsule transition storage rack 3. The capsule receiving cup 8 is driven by a first driving structure to move back and forth, and the capsule receiving cup 8 has a concave cavity 81 for receiving the capsule 4.

[0044] The first driving structure is a belt driving structure 10 with a stepping motor 101 as the driving source. The capsule receiving cup 8 is fixed on the transmission belt 102 of the belt driving structure 10. The belt driving structure 10 is arranged on the installation track 13, and a guide rail 131 extending along the preset track direction is further arranged on the installation track 13. A guide wheel 82 cooperating with the guide rail 131 is arranged on the capsule receiving cup 8.

[0045] A plurality of guiding structures arranged in one-to-one correspondence with the storage holes 61 are arranged below the capsule transition storage rack 3. When the capsule receiving cup 8 moves to a position corresponding to one of the storage holes 61, the beverage capsule 4 falling from the storage hole 61 can be guided to the concave cavity 81 of the capsule receiving cup 8 through the guiding structure at the corresponding position.

[0046] The guiding structure includes two guiding inclined plates 14 fixed below the capsule transition storage rack 6. The two guiding inclined plates 14 are located on the front and rear sides below the storage hole 61 and are arranged at intervals. The distance D between the two guiding inclined plates 14 satisfies the following conditions: the annular edge 41 of the beverage capsule 4 falling from the storage hole rests on the top inclined surfaces of the two guiding inclined plates 14, and the body of the beverage capsule 4 is located within the distance D between the two guiding inclined plates 14. When the capsule receiving cup 8 moves to a position corresponding to one of the storage holes 61, the end of the guiding inclined plate 14 at this position is located above the concave cavity 81 of the capsule receiving cup 8.

[0047] The working process and principle of this embodiment are as follows.

[0048] The belt driving structure 10 drives the capsule receiving cup 8 to move to a position corresponding to one of the storage holes 61, that is, the end of the guiding inclined plate 14 at this position is located above the concave cavity 81 of the capsule receiving cup 8.

[0049] During operation, the first solenoid iron 5 drives the blocking column 3 to retract rapidly. The lowermost beverage capsule 4 drops downward and passes through the bottom opening 22 of the capsule accommodating groove 2. Then, the first solenoid iron 5 drives the blocking column 3 to extend rapidly to block the next beverage capsule 2 located at the lowermost position, effectively ensuring that only one beverage capsule 2 drops at a time. The positioning block 91 blocks the annular edge 41 of the beverage capsule 4 that is about to slide into the storage hole 61 but is still located in the capsule accommodating groove 2, and the beverage capsule 4 located in the capsule accommodating groove 2 avoids exerting a downward pressure on the beverage capsule 4 that is about to drop onto the capsule transition storage rack 8.

[0050] Next, the second solenoid iron 9 pulls the positioning block 91 to retract, and the beverage capsule 2 drops through the storage hole 61 only between the two guiding inclined plates 14. The annular edge 41 of the beverage capsule 4 is placed on the top inclined surfaces of the two guiding inclined plates 14 and slides down into the cavity 81 of the capsule receiving cup 8 under the action of gravity. The just-dropped beverage capsule 4 drives the belt transmission structure 10 to move the capsule receiving cup 8 to the extraction position for extraction. After the extraction is completed, the belt transmission structure 10 drives the capsule receiving cup 8 to move to the de-packaging position to complete de-packaging.
