Description

Technical Field

[0001] The invention relates to the technical field of beer barrels, and in particular to an automatic beer barrel vending device. Background Art

[0002] After the customer purchases the goods, the vending machine needs to deliver the goods to the pickup port so that the customer can take the goods away. The existing vending machine structures are generally divided into four types: 1. Locker type, the vending machine is composed of many grid cabinets, and the goods are placed in the corresponding grids. After the customer purchases, the door of the cabinet for the purchased goods will be unlocked by the electromagnetic lock. The customer needs to open the cabinet door to take out the goods and then close the cabinet door; 2. Drop type, the vending machine is composed of multiple aisles, and different goods are placed in different aisles. After the customer purchases, the goods are transported to the aisle by the transmission mechanism in the aisle. The product is pushed out and falls into the pickup area. The customer opens the pickup door and takes out the product; 3. Lifting platform type, the vending machine consists of multiple aisles and a lifting platform. When shipping, the lifting platform is driven by a stepper or servo motor to move to the aisle corresponding to the product. The product is transported to the lifting platform by the conveying mechanism in the aisle. The lifting platform transports the product to the pickup port of the machine and opens the pickup door; 4. Weighing visual recognition type, the vending machine consists of multiple aisles, each aisle has a weighing sensor, and there is a camera in the machine to identify the customer's behavior of taking and putting back the product. The machine requires the customer to scan the code with his mobile phone before opening the cabinet door. After the cabinet door is opened, the customer can choose and buy at will. After the purchase is completed, close the cabinet door and the system automatically deducts the money.

[0003] The existing vending machines on the market sell goods with relatively small weight and volume, or goods that only need to be sold and do not need to be returned. However, for stainless steel barrels of craft beer, each barrel of beer is large in volume and weight (beer barrel diameter 237.5mm, height 326.5mm, weight 10kg), and the stainless steel barrel itself is a recyclable container with high manufacturing cost, so the vending machine needs to be able to sell barrels of craft beer and also recycle the empty barrels after customers drink the beer. Then, if traditional vending machines are used to sell stainless steel barrels of craft beer, there will be the following disadvantages:

[0004] 1. Disadvantages of using locker-type vending machines:

[0005] ① The structure of the machine itself is relatively simple. It only needs to install an electromagnetic lock on each grid and cooperate with the control system to realize the sales function. However, due to the need to recycle beer barrels, each barrel needs to be bound to the user. Therefore, a barrel number recognition module must be installed in each grid to read the number of the barrel sold and the number of the barrel returned by the user. In this way, since many recognition modules are required, the manufacturing cost of the machine is increased; ② Since the barrels are heavy, it may be difficult for customers to pick up and return the barrels. Either the position is too high and difficult to pick up, or the position is too low and they need to squat down to operate. In short, the user experience is not very friendly; ③ Since there are partitions between each grid of the grid machine, the fine-ground beer needs to be refrigerated and stored, the refrigeration effect of the machine will be greatly reduced; ④ There are cases where users do not close the cabinet door by themselves, resulting in the machine being unable to refrigerate, and subsequent maintenance is more difficult.

[0006] 2. Disadvantages of using drop-type vending machines:

[0007] ① As barrels are heavy, if they fall from the aisle into the pickup area, it is likely to cause damage to the barrels and the machine. If customers put their hands into the pickup area during delivery, their hands may be injured, posing a safety hazard. ② Adding a power system to the aisle, such as a conveyor belt or a screw propulsion mechanism, will increase the size of the aisle, complicate the structure, and increase costs. ③ Empty barrels cannot be recycled.

[0008] 3. Disadvantages of using lifting platform vending machines:

[0009] ① Adding a power system to the cargo aisle, such as a conveyor belt or a screw propulsion mechanism, will increase the size of the cargo aisle, complicate the structure, and increase costs; ② There is a waste of space, resulting in a larger machine size.

[0010] 4. Disadvantages of using weighing and visual recognition vending machines:

[0011] ① Since the appearance of wine barrels is consistent, but the taste of the wine inside the barrels is different, it is impossible to identify the goods taken by the user well; ② Since each barrel has a unique number, the customer and the barrel need to be bound when the customer purchases, which makes it difficult to identify the barrel number; ③ It is possible that customers will put the goods and empty barrels in the wrong place on the shelf after opening the cabinet door, disrupting the order, etc., and the equipment is poorly maintainable. Summary of the invention

[0012] 1. Technical issues to be resolved

[0013] The technical problem to be solved by the present invention is to provide an automatic beer keg vending device, whose locking mechanism can realize the locking and unlocking states of the beer keg on the cargo aisle, and when unlocked, the beer keg can be rolled out to the placement platform along the inclined cargo aisle; its conveying mechanism can convey the beer keg sent out from the cargo aisle to the pickup port for users to pick up; at the same time, a recycling shelf is also provided for recycling beer kegs, and the selling process is simplified, convenient, and safe.

[0014] (II) Technical solution

[0015] The solution adopted by the present invention to solve the above technical problems is a beer barrel automatic vending device, comprising

[0016] The fuselage has a cargo receiving port connecting the inside and the outside;

[0017] A cargo aisle shelf, used for placing beer barrels, comprising an inclined cargo aisle, wherein the delivery port of the cargo aisle is located at a low position;

[0018] A locking mechanism is provided at a delivery port on one side of the cargo aisle close to the cargo pickup port, so as to realize a locked state and an unlocked state of the beer barrel on the cargo aisle;

[0019] A conveying mechanism, used for receiving the beer kegs delivered from the cargo channel and conveying them to a place near the pickup port, comprising a placement platform for accommodating the beer kegs, wherein a side of the placement platform away from the delivery port is a free end, and the free end can rotate along a side of the placement platform close to the delivery port;

[0020] The recycling rack is used to place the recycled beer kegs, and includes a receiving port arranged near the side of the conveying mechanism. The free end of the placing platform makes a relatively upward rotational motion along the side of the placing platform near the shipping port, so as to recycle the recycled beer kegs along the placing platform through the receiving port to the recycling rack.

[0021] Preferably, the recovery rack is arranged below the material channel rack.

[0022] Preferably, the inclination angle of the cargo channel is 5°; the beer barrels are cylindrical and can roll out of the cargo channel by themselves under the action of gravity.

[0023] Specifically, according to needs, a plurality of material channel shelves arranged vertically can be set in the fuselage, and correspondingly, the delivery port of each material channel shelf is provided with the locking mechanism; when in use, the conveying mechanism performs lifting and lowering movement along the distribution direction of the material channel shelves, slides to the delivery port of any material channel shelf, and is used to receive the beer kegs taken out after being unlocked, and conveys them to the pickup port for customers to take them out; when returning the kegs, the beer kegs are placed from the pickup port to the placement platform of the conveying mechanism, and are recovered to the recovery shelf.

[0024] Furthermore, the locking mechanism includes a connecting rod assembly for locking and unlocking the beer keg on the cargo aisle, and a locking assembly for realizing the locking and unlocking of the beer keg by the connecting rod assembly; wherein, the connecting rod assembly includes a front connecting rod arranged transversely relative to the delivery port of the cargo aisle, and both ends of the front connecting rod are rotatably connected to the material aisle shelves on both sides of the cargo aisle; the locking assembly can lock the front connecting rod in a first use position located in front of the delivery port to lock the beer keg located in the cargo aisle; the locking assembly can lock the front connecting rod in a second use position located above the delivery port to unlock the beer keg located in the cargo aisle so that it can be shipped from the delivery port to the conveying mechanism.

[0025] Preferably, since the beer keg has a force tending to move toward the delivery port on the inclined cargo aisle, the beer keg will give a thrust to the front connecting rod, causing the front connecting rod to rotate around the first rotating axis and rotate in the direction of rotating open until it contacts the locking assembly and is locked, so that the connecting rod assembly is locked, thereby achieving the locking of the beer keg on the cargo aisle; when the connecting rod assembly and the locking piece are unlocked, the front connecting rod continues to rotate upward around the first rotating axis, so that the beer keg can roll out of the cargo aisle.

[0026] Furthermore, the connecting rod assembly includes a first connecting rod rotatably connected to the cargo aisle at the rotating connection of the front connecting rod, a second connecting rod hinged to the first connecting rod, and a third connecting rod hinged to the other end of the second connecting rod; the locking assembly includes a locking member used in conjunction with the third connecting rod, and an unlocking member that disengages the third connecting rod from the locking member; when the front connecting rod is rotated downward to the first use position under force, the third connecting rod is locked to the locking member to lock the beer keg to the cargo aisle; when the unlocking member applies a force to the third connecting rod to disengage it from the locking member, the front connecting rod is rotated upward to the second use position to unlock the beer keg from the cargo aisle.

[0027] Furthermore, a reset member for resetting the connecting rod assembly is provided on the cargo channel, so that the connecting rod assembly is reset to the point where the front connecting rod is in the first use position; specifically, one end of the reset member is connected to the cargo channel shelf, and the other end is connected to the other end of the first connecting rod away from the first rotating shaft.

[0028] Preferably, the front connecting rod includes a cross rod arranged laterally at the delivery port, and a connecting rod connected to both ends of the cross rod and rotatably connected to the material channel shelf at both sides of the cargo channel; and the connecting rod is rotatably connected to the material channel cargo channel through a first rotating shaft; the first connecting rod is integrally formed at the connection between the connecting rod and the first rotating shaft, and moves synchronously with the front connecting rod; one end of the second connecting rod is hinged at the center of the first connecting rod; one end of the third connecting rod is hinged at the other end of the second connecting rod, and the third connecting rod is rotatably connected to the material channel shelf through a second rotating shaft, and the locking member is provided on the material channel shelf, and is relatively provided on the second rotating shaft The axis is far away from the rear of the delivery port; a locking fitting piece that cooperates with the locking piece and is locked is hinged on the other end of the third connecting rod, and the locking fitting piece is hinged to the third connecting rod through a third rotating shaft, and a reset spring that enables the locking fitting piece to reset relative to the third connecting rod is connected between the locking fitting piece and the third connecting rod; wherein the locking fitting piece includes a locking portion and a force-bearing portion that cooperate with the locking piece and are distributed at both ends of the third connecting rod, and the third connecting rod is provided with a limiting space for limiting the locking portion, and the limiting space is formed by the cooperation of a first limiting portion that limits the clockwise rotation of the locking portion and a second limiting portion that limits the counterclockwise rotation of the locking portion;

[0029] When the beer keg gives the front connecting rod a thrust, the front connecting rod rotates around the first rotating shaft in the direction of rotating and opening (clockwise rotation); then the first connecting rod rotates around the first rotating shaft in the clockwise direction, thereby driving the second connecting rod and the end connected to the third connecting rod to move upward relatively, thereby driving the third connecting rod to rotate counterclockwise around the second rotating shaft, so that the locking fitting moves in the direction close to the locking fitting until it contacts and locks with the locking fitting, then the entire connecting rod assembly is locked, and the beer keg is locked on the cargo aisle. Specifically, when the locking fitting contacts the locking fitting, it will be subjected to a reverse force f of the locking fitting, and the reverse force f will generate a component force f1 that tends to rotate the locking fitting around the third rotating shaft. Then, the counterclockwise rotation of the third connecting rod and the clockwise rotation of the locking fitting cause the locking portion of the locking fitting to be restricted on the first limiting portion of the third connecting rod, forming a lock, so that the locking mechanism cannot rotate, and the connecting rod assembly is locked.

[0030] When a thrust is applied to the force-bearing portion of the locking fitting, causing it to rotate counterclockwise around the third rotating shaft, thereby disengaging from the locking fitting, the locking portion of the locking fitting abuts against the second limiting portion of the third connecting rod, thereby driving the third connecting rod to rotate counterclockwise around the second rotating shaft, and driving the first connecting rod and the front connecting rod to rotate clockwise around the first rotating shaft, thereby lifting the front connecting rod, so that the beer barrel can roll out of the cargo channel;

[0031] When the force applied to the force-bearing part of the locking fitting is cancelled, the reset member will give a force to the first connecting rod, so that the first connecting rod and the front connecting rod will reset by moving counterclockwise around the first rotating axis, and the reset spring will give a force to the locking fitting, so that the locking fitting will reset, and then another beer keg will be unlocked and roll down until it is locked by the front connecting rod.

[0032] Furthermore, the connecting rod assembly also includes a rear connecting rod arranged on a side of the rotation axis of the connecting rod assembly away from the front connecting rod. When the front connecting rod rotates and moves downward to a first use position, the rear connecting rod rotates and moves upward to above the beer barrel on the cargo aisle; when the front connecting rod rotates and moves upward to a second use position, the rear connecting rod rotates and moves downward until it abuts against and locks the beer barrel behind it.

[0033] Preferably, the connecting rod extends away from one side of the front connecting rod, so that the center of the connecting rod is rotatably connected to the first rotating shaft, and the other end of the connecting rod is connected to the rear connecting rod; the front connecting rod and the rear connecting rod are a seesaw structure relative to the first rotating shaft; when the front connecting rod is locked in the first use position, the rear connecting rod is relatively located above the cargo aisle; when the front connecting rod is unlocked and rotated to the second use position, the rear connecting rod rotates downward around the first rotating shaft and blocks the beer keg located at the rear so that it does not roll; when the beer keg in the front rolls out, the connecting rod assembly is reset under the action of the reset member, and the rear connecting rod detaches from the beer keg, then, the beer keg at the rear continues to roll until it pushes the front connecting rod until the connecting rod assembly is locked by the cooperation of the locking mating member and the locking member.

[0034] Furthermore, the transport mechanism includes a lifting platform that can perform lifting and lowering movements along the height direction of the fuselage, and a first driving component that provides power to the lifting platform; wherein the lifting platform includes a supporting platform, and a placing platform whose one end is rotatably connected to an end of the supporting platform close to the shipping port; a second driving component is provided on the supporting platform for driving the free end of the placing platform to perform rotational movement along the connection between the placing platform and the supporting platform.

[0035] Preferably, the first driving assembly includes a stepper motor, a worm reducer, a synchronous wheel, and a synchronous belt. The stepper motor adopts an 86 stepper motor with a maximum torque of 12N.M. The synchronous belt is connected to the lifting platform, and the lifting platform is provided with a slider. The fuselage is provided with a vertically arranged slide rail. The stepper motor drives the synchronous wheel and the synchronous belt to move after being decelerated by the worm reducer, so that the lifting platform is lifted and lowered along the slide rail through the synchronous belt, so as to drive the lifting platform to run to the delivery port to receive the rolled beer kegs.

[0036] Furthermore, the second driving assembly includes a second driving member, a rotating shaft connected to the second driving member and capable of rotating around its own axis, and a platform support rod member connected to the rotating shaft at one end and in conflict with the supporting platform at the other end, and the second driving member is a worm reduction motor; the second driving member drives the rotating shaft to rotate forward or reversely, so as to drive the end of the platform support rod member connected to the rotating shaft to perform a lifting movement relative to the supporting platform, so as to realize the rotational rising and rotating falling movement of the free end of the placement platform.

[0037] Furthermore, the platform support rod member includes a matching shaft that matches the rotating shaft, wherein a cavity for the rotating shaft to extend into is provided in the matching shaft, and the inner wall portion of the cavity extends inward to form a protrusion, and correspondingly, the rotating shaft includes an insertion shaft that extends into the cavity and can rotate along the inner wall of the protrusion, and the outer wall of the insertion shaft extends outward to form a convex rib that can rotate along the inner wall of the cavity; when the convex rib rotates until it abuts against the protrusion, the rotating shaft drives the matching shaft to move synchronously, and when the convex rib rotates along the inner wall of the cavity, the matching shaft will not be driven.

[0038] Furthermore, an unlocking member for realizing an unlocked state of the beer keg on the cargo aisle is connected to the rotating shaft, and the unlocking member rotates synchronously with the rotating shaft.

[0039] Preferably, a synchronous wheel is connected to the rotating shaft, and the synchronous wheel is connected to another synchronous wheel on the other side through a synchronous belt, and the synchronous wheel there is connected to a universal joint for synchronous movement, and the unlocking member is connected to the other side of the universal joint;

[0040] When the second driving member is started, it drives the rotating shaft to rotate in the forward direction (counterclockwise), and there is a section of the stroke in which the convex rib on the rotating shaft rotates along the inner wall of the cavity. At this time, the mating shaft and the rotating shaft are in a disengaged state, that is, the mating shaft will not be driven; then, in this process, the rotating shaft will drive the universal joint to rotate synchronously, thereby driving the unlocking member to rotate in the direction close to the locking mating member, thereby applying force to the force-bearing part of the locking mating member, thereby unlocking the locking mechanism; after the beer barrel rolls from the cargo channel to the platform, the NFC card reader module of the platform reads the barrel number, and after binding it with the customer's account, the lifting platform will move to the delivery port of the cargo channel, receive the rolled beer barrel, and deliver it to the pickup port for customers to pick up;

[0041] When the keg needs to be returned, the lifting platform is close to the receiving port of the recycling rack, and the second driving member is started, driving the rotating shaft to rotate in the forward direction (counterclockwise). Then, when the rib on the rotating shaft rotates along the inner wall of the cavity until it abuts against the raised portion, the rotating shaft will drive the matching shaft to rotate, thereby driving the platform support rod to make a supporting movement relative to the supporting platform, and driving the free end of the placing platform to rotate and rise around the connection between the placing platform and the supporting platform, so that the beer keg will roll into the recycling rack in the receiving port; after that, the second driving member is started, driving the rotating shaft to rotate in the opposite direction (clockwise), so that the placing platform is reset.

[0042] Furthermore, the support platform includes a fixed plate, and a support plate slidably connected to the fixed plate and connected to the placement platform; the support plate slides along the fixed plate toward or away from the pickup port, and the support plate can drive the placement platform to extend out of the pickup port to facilitate user pickup, wherein the sliding movement of the support plate is driven by a planetary reduction motor.

[0043] Specifically, after the beer barrel is purchased, it rolls from the cargo aisle to the platform, and the NFC card reader module of the platform reads the barrel number. After binding with the customer's account, the lifting platform moves to the delivery port of the cargo aisle to receive the rolled beer barrel; then, the support plate and the placement platform are driven by the planetary reduction motor to slide along the support plate to the delivery port, and the beer barrel is sent out of the machine body for the convenience of customers to take;

[0044] After the customer takes the beer keg away, the support plate drives the placement platform to automatically retract;

[0045] After the customer clicks the return barrel button on the vending machine screen, the support plate drives the placement platform to extend out of the pickup port, making it convenient for the customer to place the empty beer barrel on the placement platform; when the customer places the beer barrel on the placement platform, the NFC card reader module recognizes the barrel number, and the support plate and the placement platform are driven by the planetary reduction motor to reset; after resetting, they descend to the receiving port of the bottom recycling shelf to return the barrel.

[0046] (III) Beneficial effects

[0075] This embodiment:

[0076] like Figure 1-Figure 24As shown, an automatic beer keg vending device of this embodiment includes a body 1, which has a pickup port 11 communicating with the inside and outside; a channel shelf 2, which is used to place beer kegs, including an inclined cargo channel 21, and the delivery port 211 of the cargo channel 21 is located at a low position; a locking mechanism 3, which is arranged at the delivery port 211 of the cargo channel 21 close to the pickup port 11, so as to realize the locking state and unlocking state of the beer keg on the cargo channel 21; a conveying mechanism 4, which is used to receive the beer kegs delivered by the cargo channel 21 and convey them to a place close to the pickup port 11, and includes a placement platform for accommodating beer kegs. The platform 41 is a free end, wherein the side of the placing platform 41 away from the delivery port 211 is a free end, and the free end can rotate along the side of the placing platform 41 close to the delivery port 211; the recycling shelf 5 is used to place the recycled beer barrels, including a receiving port 51 arranged close to the side of the conveying mechanism 4, and the free end of the placing platform 41 rotates relatively upward along the side of the placing platform 41 close to the delivery port 211, so as to recycle the recycled beer barrels along the placing platform 41 through the receiving port 51 to the recycling shelf 5. Preferably, the recycling shelf 5 is arranged below the material channel shelf 2. Preferably, the inclination angle of the cargo channel 21 is 5°; taking advantage of the rolling characteristics of the beer barrels as cylindrical bodies, the beer barrels are allowed to roll out of the cargo channel 21 by themselves under the action of gravity. Specifically, according to needs, a plurality of material channel shelves 2 arranged up and down can be set in the fuselage 1, and correspondingly, the delivery port 211 of each of the material channel shelves 2 is provided with the locking mechanism 3; when in use, the conveying mechanism 4 performs lifting and lowering movement along the distribution direction of the material channel shelves 2, and slides to the delivery port 211 of any material channel shelf 2, and is used to receive the beer kegs taken out after being unlocked, and convey them to the pickup port 11 for customers to take them out; when returning the kegs, the beer kegs are placed from the pickup port 11 to the placement platform 41 of the conveying mechanism 4, and are recovered to the recovery shelf 5.

[0077] like Figure 2 , Figure 4 , Figure 18-Figure 24As shown, further, the locking mechanism 3 includes a connecting rod assembly 31 for locking and unlocking the beer keg on the cargo aisle 21, and a locking assembly 32 for realizing the locking and unlocking of the beer keg by the connecting rod assembly 31; wherein, the connecting rod assembly 31 includes a front connecting rod 311 arranged transversely relative to the delivery port 211 of the cargo aisle 21, and both ends of the front connecting rod 311 are rotatably connected to the aisle shelf 2 on both sides of the cargo aisle 21; the locking assembly 32 can lock the front connecting rod 311 in a first use position located in front of the delivery port 211 to lock the beer keg located in the cargo aisle 21; the locking assembly 32 can lock the front connecting rod 311 in a second use position located above the delivery port 211 to unlock the beer keg located in the cargo aisle 21, so that it can be shipped from the delivery port 211 to the conveying mechanism 4.
